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

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

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

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

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

682 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
684 * Added new configuration options and blocks:
685 keepalive_secs, reconnect_count, reconnect_interval,
686 reconnect_interval_max, reconnect_keep_trying and
687 require_reverser_lookup. Added ConnectionParam block, and
688 implemented the connection parameters when connecting as
689 initiator and when accepting connections as responder.

692 whether given configuration value has been given already.
694 Affected files silcd/serverconfig.[c], server.[c].
696 * Splitted the doc/example_silcd.conf.in. Separated the crypto
697 algorithm parts and created new file silcalgs.conf, that
698 is now included from the example_silcd.conf.in.
700 * Optimized the silc_server_connect_to_router_second to take
701 the connection configuration object from the SilcServerConnection
702 object instead of finding it during the connecting phase.
703 Added the configuration object to SilcServerConnection struct.
704 Affected files silcd/server_internal.h, server.c.

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

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

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

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

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

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

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

975 * Added server & router operator statistics updating. Affected
976 file silcd/packet_receive.c and silcd/command.c.
978 * Fixed the SERVER_SIGNOFF notify handling on normal server
979 not to save the history information for clients. Same was
980 fixed earlier in remove_clients_by_server function, but not
981 here. Affected file silcd/packet_receive.c.
983 * Raised the default connection-retry count from 4 to 7 in
984 server. Affected file silcd/server.h.
986 * Cancel any possible reconnect timeouts when we start the
987 key exchange. Affected file silcd/server.c.
989 * Do not reconnect on connection failure when SCONNECT was

994 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
996 * Fixed the NICK command to always give the unformatted
997 nickname to the one giving the NICK command. If unformatted
998 nickname is cached already it will be formatted and the
999 local entry will always get the unformatted nickname.
1000 Affected file lib/silcclient/idlist.c.
1002 * Fixed some double frees from client library commands.
1003 Affected file is lib/silcclient/command.c.
1005 * Fixed CUMODE command in server to assure that no one can
1006 change founder's mode than the founder itself, there was a
1007 little bug. Affected file silcd/command.c.
1009 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1011 * Removed the SilcClientCommandDestructor from the client
1012 libary, it is not needed anymore. Affected files are
1013 lib/silcclient/silcapi.h, command[_reply].[ch],
1014 client_notify, idlist.c.
1016 * Fixed GETKEY command to first resolve client, and then
1017 resolve the server only if the client was not found, instead
1018 of resolving both at the same time. Affected file is
1019 lib/silcclient/command.c.
1021 * Added silc_client_start_key_exchange_cb and lookup the
1022 remote hostname and IP address before starting the key
1023 exchange with server. The affected file is
1024 lib/silcclient/client.c.
1026 * The server's public key is now saved using the IP address
1027 of the server and not the servername for the filename.
1028 The hostname public key filename is checked as an fall back
1029 method if the IP address based filename is not found.
1031 Fixed the GETKEY command to save the fetched server key
1032 in correct filename.
1034 Print the remote server's hostname now when new key is
1035 received during connection process. Affected file is
1036 irssi/src/silc/core/client_ops.c.
1038 * Return always our own public key to the client if it asks
1039 for it with GETKEY command. Affected file silcd/command.c.
1041 * Removed the use_auto_addr variable from default config
1042 file since it was in wrong section. Affected file is
1045 * Fixed TOPIC_CHANGE notification to not route it when it
1046 was sent using silc_server_send_notify_to_channel function.
1047 Affected file silcd/command.c.
1049 * Fixed silc_server_send_notify_kicked to send the kicker's
1050 Client ID also, it was missing. Affected files are
1051 silcd/command.c, silcd/packet_send.[ch].
1053 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1055 * Do not save client history information in SERVER_SIGNOFF.
1056 Fixes the bug in normal server that it does not detect
1057 the client becoming valid after the server becomes back
1058 online. Affected file silcd/server_util.c.
1060 * Added `sock_error' field into the SilcSocketConnection
1061 context. When error occurs during socket operation (read
1062 or write) the error is saved. Added also new function
1063 silc_socket_get_error to return human readable socket error
1064 message. Affected files are lib/silcutil/silcsockconn.[ch],
1065 lib/silcutil/unix/silcunixsockconn.c, and
1066 lib/silcutil/win32/silcwin32sockconn.c.
1068 * The server now prints the socket error message in the
1069 signoff for client. Affected file silcd/server.c.
1071 * Fixed the `created' channel information sending from router
1072 to server in JOIN command. Checks now whether the channel
1073 really was created or not and set it according that.
1075 Fixed the JOIN command to use the client entry's current
1076 ID during the joining procedure instead of the one it sent
1077 in the command (it is checked though), since it can change
1078 between the packet processing and command processing, and
1079 would just case unnecessary pain in the client end. Affected
1080 file silcd/command.c.
1082 * Fixed a channel key payload sending to use correct channel
1083 ID when the server was forced to change the channel's ID by
1084 router. Router sent the key payload with the old Channel ID.
1085 Affected file silcd/packet_receive.c.
1087 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1089 * Call silc_server_save_channel_key only if the key payload
1090 was provided in the JOIN command's command reply. Affected
1091 file silcd/command_reply.c.
1093 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1095 * Fixed silc_mp_sizeinbase to return the value correctly with
1096 MPI. Affected file lib/silcmath/mp_mpi.c.
1098 * Fixed the stop_server signal to correctly stop the scheduler
1099 and gracefully stop the server when SIGTERM or SIGINT signals
1100 are received. Affected file silcd/silcd.c.
1102 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1104 * Simple handling of TERM and HUP signals. Also added some log
1105 flushing call around. Affected file is
1108 * Fixed small bugs in silclog.c. Now buffering output will take
1109 effect after 10 seconds since startup: This will ensure that
1110 no important startup messages are lost. Also output redirection
1111 will preserve original format ([Date] [Type] message).
1112 Affected file is lib/silcutil/silclog.c.
1114 * Added two options to the config file, in the logging section:
1115 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1116 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1118 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1120 * Do not print the warning about log files not being initialized
1121 more than once to avoid excess logging. Affected file is
1122 lib/silcutil/silclog.c.
1124 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1125 the SIM copying in make install in Makefile.am.pre.
1127 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1129 * Rewritten silclog APIs. Globally interesting changes follows:
1130 silc_log_set_files() changed to silc_log_set_file().
1131 silc_log_set_callbacks() changed to silc_log_set_callback().
1132 ROBOdoc documented silclog header file.
1133 SilcLogCb now returns bool to wether inihibit the default
1134 handler or not (to keep the old behaviour return always TRUE).
1135 The new APIs should also fix the problem of the
1136 silcd_error.log file that was written in the current directory.
1139 Log files streams will remain opened after silc_log_set_file()
1140 call, means less CPU usage notably on high traffic servers.
1141 File streams are now full buffered, and flushed to the disk
1142 every 5 minutes, lesses HD activity and CPU usage.
1143 Messages can be redirected, allowing admins to configure
1144 one single logfile for all server messages.
1145 the silc_log_quick global variable to activate fast-logging.
1146 Affected files lib/silcutil/silclog.[ch]
1148 * Changed some code to conform new silclog APIs. Affected
1149 files are doc/example_silcd.conf.in, silcd/server.c
1150 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1153 * Fixed a memory leak that could occur in some situations.
1154 Affected file silcd/serverconfig.c.
1156 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1158 * Added the silc_client_del_client to remove the client from
1159 all channels as well. Affected file lib/silcclient/idlist.c.
1161 * Fixed the client library to correctly remove the client
1162 from all channels when the client entry is being destroyed.
1163 Affected file lib/silcclient/client_notify.c, command.c.
1165 * Added auto-nicking support to the client library. If the
1166 applicatio now sets client->nickname it will be sent to the
1167 server after connecting by the library. This way for example
1168 SILCNICK (or IRCNICK) environment variables will have effect
1169 and always change the nickname automatically to whatever
1170 it is wanted. Affected file lib/silcclient/client.[ch].
1172 * Renamed silc_server_command_bad_chars to the
1173 silc_server_name_bad_chars and moved it to the
1174 silcd/server_util.[ch]. Added also new function
1175 silc_server_name_modify_bad to return nickname that
1176 includes bad characters as new nickname without those
1177 bad characters. This check and modify is now used in
1178 silc_server_new_client when the username is initially set
1179 as nickname, so it must be checked to be valid nickname.
1180 Affected file silcd/packet_receive.c.
1182 * The nickname length is now taken from the packet for real
1183 and not trusted to strlen() since it clearly can return
1184 wrong length for nickname including bad characters. This
1185 also applies to channel names. Affected file silcd/command.c.
1187 * Removed the lib/silcsilm/modules directory. Modules are now
1188 compiled into the lib/silcsim. Fixed the copying of the
1189 modules to follow symbolic links in Makefile.am.pre.
1191 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1193 * Fixed silc_string_regexify list creation. Fixes bugs with
1194 BAN and INVITE commands in server. The affected file is
1195 lib/silcutil/unix/silcunixutil.c.
1197 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1199 * Removed the command destructor entirely from the server's
1200 command and command reply routines. It is not needed, and
1201 its usage was buggy and caused crashes. Affected files are
1202 silcd/command[_reply].[ch].
1204 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1206 * Cancel protocol and NULL sock->protocol if timeout
1207 occurred during protocol. Affected file silcd/server.c.
1209 * Cancel protocol timeouts always before calling the final
1210 callback, to assure that after final callback is called
1211 no other state will be called for the protocol anymore.
1212 Affected file silcd/protocol.c.
1214 * Print error log if incoming connection configuration could
1215 not be found. Affected file silcd/server.c.
1217 * Fixed JOIN command to correctly save the founder mode
1218 to the client on normal SILC server, when the channel
1219 was created by the router. Affected file silcd/command.c.
1221 * Fixed LIST command (hopefully) to send correct reply
1222 packets. Affected file silcd/command.c.
1224 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1226 * The silc_packet_receive_process now returns FALSE if the
1227 read data was invalid packet, and TRUE if it was ok.
1229 The server now checks that if unauthenticated connection
1230 sends data and its processing fails the server will close
1231 the connection since it could be a malicious flooder.
1233 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1235 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1237 * Make sure the warning about error opening a log file is
1238 printed only once and not everytime it fails (produces
1239 too much useless log). Affected file lib/silcutil/silclog.c.
1241 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1243 * Made the silc_server_daemonise() function more readable.
1244 Affected file silcd/server.c.
1246 * Pid file is now optional, the user may comment it out from
1247 the config file. Removed define SILC_SERVER_PID_FILE, we
1248 don't need a default any longer. Affected file
1249 configure.in.pre, lib/Makefile.am.pre.
1251 * Make some use of the pid file. The server now dies at startup
1252 if it detects a valid pid file on his path. The server would
1253 die anyway in this circumstance, because of the bind() failure.
1254 Affected file silcd/silcd.c.
1256 * No longer compiling lib/dotconf.
1258 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1260 * Fixed JOIN command parsing not to crash. Affected file
1261 lib/silcclient/command.c.
1263 * Fied the NICK_CHANGE notify to add the new client entry
1264 even it is resolved. This removes an <[unknown]> nick
1265 thingy bug in the client. Affected file is
1266 lib/silcclient/client_notify.c.
1268 * Do not try to allocate 0 bytes (efence does not like it)
1269 in lib/silccore/silccomand.c when encoding payload.
1271 * Do not take IRCNICK as nickname in Irssi SILC client since
1272 it is not possible to set nickname before hand connecting
1273 the server (TODO has an entry about adding auto-nicking
1276 * Changed the silc_server_command_pending to check whether
1277 there already exists an pending entry with the specified
1278 command, command identifier and pending callback. This is
1279 to fix IDENTIFY and WHOIS related crashes that may register
1280 multiple pending commands with same identifier. Affected
1281 file silcd/command.c.
1283 * Fixed the server to reconnect to the router even if it
1284 was already reconnecting and EOF was received. This to
1285 fix a possibility that the server wouldn't ever try to
1286 auto-reconnect to the router. Affected file silcd/server.c.
1288 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1290 * Fixed the server's password authentication to use the
1291 length of the locally saved password, and not the one
1292 sent in the packet. Affected file silcd/protocol.c.
1294 * Fixed same password authentication problem in the
1295 Authentication Payload handling routines in
1296 lib/silccore/silcauth.c.
1298 * Yet another password authentication problem fixed with
1299 channel password handling in silcd/command.c.
1301 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1303 * If first character of string in silc_parse_userfqdn is '@'
1304 then do not parse it. Affected file is
1305 lib/silcutil/silcutil.c.
1307 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1309 * Fixed minor bug in IDENTIFY command reply sending, which
1310 caused various weird problems during JOIN when it was
1311 resolving names for users. Affected file silcd/command.c.
1313 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1315 * Fixed the IDENTIFY command reply sending to chech better valid
1316 clients. It was possible to send incomplete list of replies.
1317 Affected file silcd/command.c.
1319 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1321 * Added silc_client_command[s]_[un]register functions now to
1322 dynamically register the commands in client library. Removed
1323 the static table of commands. This allows the client library
1324 to call commands without causing the application to know about
1325 what commands library has called.
1327 Removed the INFO command reply kludge to detect when the command
1328 was called by library. Now library use its own command reply
1329 function for INFO command.
1331 Added function silc_client_command_call to call a command.
1332 Application can use it to call command, not access the structure
1335 Now all commands that are sent by the client library (not
1336 explicitly sent by application) use own command reply functions.
1338 Affected files around lib/silcclient/ and in
1339 irssi/src/silc/core/.
1341 * Fixed the WHOIS command reply sending to chech better valid
1342 clients. It was possible to send incomplete list of replies.
1344 Fixed the WHOIS and IDENTIFY to send the request to router
1345 if normal server did not do it and did not find any results.
1347 Affected file silcd/command.c.
1349 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1351 * Moved the internal data from SilcClient context into its
1352 own file, not accesible to application. Affected files
1353 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1354 and other files in client library.
1356 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1358 * Added doc/examples installation target in Makefile.am.pre.
1361 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1363 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1364 commands the found client entry will be removed from the
1365 cache, after notifying application about the error. Affected
1366 file lib/silcclient/command_reply.c.
1368 * Changed the /MSG to check for exact nickname user gave, and
1369 not let `nick' match `nick@host' if it is only one found. Now,
1370 user must type the exact nickname (like nick@host2) even if
1371 there are no more than one same nicks found. This is to avoid
1372 a possibility of sending nickname to wrong nickname since
1373 `nick' could match `nick@host'. Affected file is
1374 irssi/src/core/silc-servers.c.
1376 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1378 * Do not print "you are now server operator" or similar when
1379 giving /away command. Affected files are
1380 irssi/src/silc/core/client_ops.c, silc-servers.h.
1382 * Made the silc_server_command_pending_error_check to send
1383 the same command reply payload it received back to the
1384 original sender of the command. This way all arguments
1385 that was received by the server will be received by the
1386 client too. Affected file silcd/command.c.
1388 * Added the silc_idcache_add to return the created cache entry
1389 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1391 * Add global clients to expire if they are not on any channel.
1392 This is because normal server will never know if they signoff
1393 if they are not on any channel. The cache expiry will take
1394 case of these entries. This is done by normal servers only.
1395 The affected files are silcd/command_reply.c,
1396 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1398 * If server receives invalid ID notification for WHOIS or
1399 IDENTIFY and the ID exists in the lists, it is removed.
1400 Affected file silcd/command_reply.c.
1402 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1403 in client then client entry that it matches is searched and
1404 the nickname is printed on the screen for user. Affected
1405 file irssi/src/silc/core/client_ops.c.
1407 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1409 * Use cache entry expire time in the LIST command reply to
1410 purge old entries from the cache after the LIST command
1411 reply has been received. This way we don't have non-existent
1412 entries in the cache for too long. Affected file is
1413 silcd/command_reply.c.
1415 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1417 * If we are normal server, and we've not resolved client info
1418 in WHOIS or IDENTIFY from router, and it is global client,
1419 we'll check whether it is on some channel. If it is not
1420 then we cannot be sure about its validity and will resolve it
1421 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1422 file silcd/command.c.
1424 * Search channel by name (if possible) rather than by ID
1425 in IDENTIFY command's command reply. Affected file is
1426 silcd/command_reply.c.
1428 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1430 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1431 Updated specs and implemented it. Affected file silcd/command.c,
1432 silcd/packet_send.c and silcd/packet_receive.c.
1434 * Implemented the <founder auth> payload handling in the JOIN
1435 command. If provided all conditions for channel joining
1436 except requirement to provide correct passphrase can be
1437 overrided by the channel founder. Updated the protocol specs.
1438 Affected file silcd/command.c.
1440 Added support for founder auth in JOIN command in client
1441 library. Fixed the parsing of the JOIN command now to support
1442 all options as they should be. The affected file is
1443 lib/silcclient/command.c.
1445 * Optimized the WHOIS and IDENTIFY commands to send the request
1446 to router only if it includes nicknames or other names. If
1447 they include only IDs then check the local cache first before
1448 routing. Affected file is silcd/command.c.
1450 * Added channels topic announcements. Affected file is
1451 silcd/packet_receive.c and silcd/server.c.
1453 * Fixed the silc_server_send_notify_topic_set to really destine
1454 the packet to channel. Affected file silcd/packet_send.c.
1456 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1457 library. Affected file lib/silcclient/client_notify.c.
1459 * Added UMODE announcements. Affected file silcd/server.c.
1461 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1463 * Memory leak fixes in:
1465 lib/silcutil/silcsockconn.c
1466 lib/silcske/silcske.c
1467 lib/silcske/groups.c
1469 lib/silccrypt/silcpkcs.c
1470 lib/silccore/silccommand.c
1471 lib/silccore/silcidcache.c
1476 * ROBOdoc documented the lib/silcske/groups.h file and a
1477 bit changed the interface for better.
1479 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1481 * Update the client entry context in the ID cache after
1482 nick change. Affected file lib/silcclient/command.c.
1483 Fixes the CUMODE command when regaining founder privileges,
1484 and a little WHOIS problem.
1486 * Fixed silc_net_gethostbyname to correctly call the
1487 inet_ntop. Affected file lib/silcutil/silcnet.c.
1489 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1491 * Added IPv6 support checking to the configure.in.pre, added
1492 also --enable-ipv6 option to override the check. Affected
1493 file configure.in.pre.
1495 * The silc_thread_create now calls the start function
1496 directly if threads support is not compiled in. Removes
1497 ugly #ifdef's from generic code. Affected files are
1498 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1500 * Added silc_net_gethostby[name/addr]_async to asynchronously
1501 resolve. Affected files are lib/silcutil/silcnet.[ch].
1503 * Added support for rendering IPv6 based server, client and
1504 channel IDs. Affected file lib/silcutil/silcutil.c.
1506 * Added support for creating IPv6 based server IDs. Affected
1507 file is silcd/serverid.c.
1509 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1511 * Added silc_net_gethostby[addr/name] into the
1512 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1513 routines. Added silc_net_is_ip[4/6]. Affected file is
1514 lib/silcutil/unix/silcunixnet.c. All routines that take
1515 address as argument now supports both IPv4 and IPv6 addresses.
1517 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1519 * Fixed LIST command reply sending in server. Affected file
1522 * Server now sends the kicker's client ID in the KICK notify
1523 to the kicked client. Affected file silcd/command.c.
1525 * The client library now parses the kickers client ID and
1526 UI displays it. Affected files lib/silcclient/client_notify.c
1527 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1529 * Made all payload parsing function prototypes consistent.
1530 They all take now const unsigned char * and uint32 pair as
1531 the payload data instead of SilcBuffer. Changes all around
1532 the source tree. Other unsigned char* -> const unsigned char*
1533 changes around the tree as well.
1535 * Optimized SFTP client and server packet sending not to
1536 allocate new buffer for each packet but to recycle the
1537 first allocated buffer. Affected files are
1538 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1540 * Optimized the SFTP client to use SilcList instead of
1541 SilcDList for requests, because it is faster. Affected file
1542 is lib/silcsftp/sftp_client.c.
1544 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1545 into lib/silccore/silcid.[ch].
1547 Renamed silcpayload.[ch] into silcargument.[ch].
1549 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1551 * If client entry is deleted with active key agreement
1552 session, abort the session.
1554 The silc_client_abort_key_agreement now calls the completion
1555 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1557 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1560 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1562 * Don't use __restrict in older GCC's. Affected file is
1563 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1565 * silc_net_localhost now attempts to reverse lookup the
1566 IP/hostname. Affected file lib/silcutil/silcnet.c.
1568 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1569 command. It can be used to gain founder privileges at
1570 the same time when joining the channel.
1572 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1573 kicker's client ID as well. Updated protocol specs.
1575 Defined that the server must send SILC_COMMAND_IDENTIFY
1576 command reply with error status to client who sent
1577 private message with invalid client ID.
1579 Updated the protocol specification.
1581 * Added silc_server_send_command_reply to send any
1582 command reply. Affected file silcd/packet_send.[ch].
1584 * Added silc_id_payload_encode_data to encode ID payload
1585 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1587 * The server now send IDENTIFY command reply with error
1588 status if client ID in private message is invalid. Affected
1589 file silcd/packet_receive.c.
1591 * Save the server key file with server's IP address in
1592 the filename instead of hostname. The affected file is
1593 irssi/src/silc/core/client_ops.c.
1595 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1597 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1600 * Added libtool support for compiling shared objects in
1601 lib/silcsim. Affected file configure.in.pre and
1602 lib/silcsim/Makefile.am. Original patch by cras.
1604 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1606 * Pid file configuration, and server's config file fixes
1607 patch by toma. Updated CREDITS file.
1609 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1611 * Fixed silc_client_channel_message to not try to decrypt
1612 the message twice if it resolved the destination client
1613 information. This could cause of dropping one channel
1614 message. Affected file lib/silcclient/client_channel.c.
1616 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1618 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1619 lib/silcclient/client.c. This function is used when the SILC
1620 Client is run under some other scheduler, or event loop or
1621 main loop. On GUI applications, for example this may be
1622 desired to used to run the client under the GUI application's
1623 main loop. Typically the GUI application would register an
1624 idle task that calls this function multiple times in a second
1625 to quickly process the SILC specific data.
1627 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1629 * Fixed silc_server_drop() for dropping the supplementary
1630 groups as well, this could cause a security hole on some
1633 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1635 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1638 * Write PID file after dropping privileges. Added -F option
1639 to run server on foreground. A patch by debolaz.
1640 Affected files silcd/server.c, silcd/silcd.c.
1642 * Fixed MOTD to return the MOTD file server name. Affected
1643 file silcd/command.c.
1645 * Added INFO command reply handling to the Irssi SILC Client.
1646 Affected file irssi/src/silc/core/client_ops.c.
1648 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1650 * Fixed the silc_idcache_list_* routines to really support
1651 the dynamic list. Fixes a crash. Affected file is
1652 lib/silccore/silcidcache.c.
1654 * Fixed the LIST command reply to really call LIST command's
1655 pending callbacks. Affected file silcd/command_reply.c.
1657 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1659 * Update conn->local_entry->nickname after giving NICK
1660 command. Affected file lib/silcclient/command.c.
1662 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1664 * Added the [pid] option to the silcd configuration file
1666 Affected files: serverconfig.[ch] and silcd.c
1668 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1670 * Save fingerprint in WHOIS command reply in server.
1671 Affected file silcd/command_reply.c.
1673 * Fixed NICK commands pending callback registration.
1674 Affected file lib/silcclient/command.c.
1676 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1678 * Use ++server->cmd_ident when sending commands in server,
1679 instead of random number. Affected file silcd/command.c.
1681 * Fixed GETKEY command reply to call actually GETKEY pending
1682 command callbacks. Affected file silcd/command_reply.c.
1684 * A bit stricter check for nicknames. Check for same nickname
1685 in NICK command also. Affected file silcd/command.c.
1687 * Do not call INFO command everytime client ID changes, only
1688 during first connecting. Affected file lib/silcclient/client.c.
1690 * Set the new nickname only after successful command reply for
1691 NICK command is returned by server. Affected file
1692 lib/silcclient/command.c.
1694 * Remove nicknames from nicklist during server_signoff notify.
1695 Should fix /NAMES bit more. The affected file is
1696 irssi/src/silc/core/silc-channels.c.
1698 * Added `fingerprint' field to the SilcIDListData in the
1699 silcd/idlist.h to hold the fingerprint of the client's
1702 Send the fingerprint of the client's public key in WHOIS
1705 Affected files silcd/command.c, and silcd/idlist.[ch].
1707 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1708 create fingerprint from given data.
1710 * Show the fingerprint of the client's public key in WHOIS.
1711 Affected files irssi/src/module-formats.[ch] and
1712 irssi/src/silc/core/client_ops.c.
1714 * Format the multiple same nicknames also during JOIN and
1715 NICK_CHANGE notifys. Affected file is
1716 lib/silcclient/client_notify.c.
1718 * Do not print error on screen for invalid private message
1719 payload since it can come if someone is sending private
1720 messages with wrong key. Affected file
1721 lib/silccore/silcprivate.c.
1723 * Fixed multiple concurrent /PING crash. Affected file
1724 lib/silcclient/command.c.
1726 * Changed the wrong ID encoding. All IP addresses must be
1727 in MSB first order in encoded format. They were encoded
1728 wrong and was in LSB format. Affected files are
1729 silcd/serverid.c, lib/silcutil/silcutil.c.
1731 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1733 * Call the `connect' client operation through the scheduler
1734 in case of error. Affected file lib/silcclient/client.c.
1736 * Call the `failure' client operation even if the error
1737 occurred locally during a protocol. Affected file is
1738 lib/silcclient/protocol.c.
1740 * Added support of sending LIST command to router from normal
1741 server. This way normal server can get list of all channels
1742 in the network too. Fixed the channel list sending in the
1743 server too. Affected files are silcd/command.c, and
1744 silcd/command_reply.[ch].
1746 * Added silc_server_update_channels_by_server and
1747 silc_server_remove_channels_by_server. They are used during
1748 disconnection of primary router and in backup router protocol.
1749 Affected file silcd/server_util.[ch], silcd/server.c and
1750 silcd/server_backup.c.
1752 * Fixed channel adding to global list in IDENTIFY command
1753 reply in server. Affected file silcd/command_reply.c.
1755 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1757 * If the incoming packet type is REKEY or REKEY_DONE process
1758 that packet always synchronously. Fixes yet another MAC
1759 failed error on slow (dialup) connections. Affected file
1760 lib/silcclient/client.c and silcd/server.c.
1762 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1764 * Call check_version SKE callback for initiator too. Affected
1765 file lib/silcske/silcske.c.
1767 * Implemented fix for security hole found in the SKE that was
1768 fixed in the specification few days back; the initiator's
1769 public key is now added to the HASH value computation.
1770 Added backwards support for the old way of doing it too, for
1771 old clients and old servers. Affected file is
1772 lib/silcske/silcske.c.
1774 * Enabled mutual authentication by default in SKE. If initiator
1775 is not providing mutual authentication the responder will
1776 force it. This will provide the proof of posession of the
1777 private key for responder. The affected files are
1778 lib/silcclient/protocol.c and silcd/protocol.c.
1780 * Do not cache anymore the server's public key during SKE.
1781 We do mutual authentication so the proof of posession of
1782 private key is done, and if the server is authenticated in
1783 conn auth protocol with public key we must have the public
1784 key already. Affected file silcd/protocol.c.
1786 * Added new global debug variable: silc_debug_hexdump. If
1787 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1788 file lib/silcutil/silclog.[ch].
1790 * Fixed compilation warning due to char * -> const char *.
1791 Affected files lib/silcutil/silcnet.h, and
1792 lib/silccore/silcauth.[ch].
1794 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1796 * Fixed CMODE command when new channel key was created. If
1797 the creation failed the old key was removed. Next time giving
1798 same command would crash the server since the old key was
1799 freed already. Affected file silcd/command.c.
1801 * Fixed the silc_server_announce_get_channels to not crash
1802 on reconnect. Affected file silcd/server.c.
1804 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1806 * Added silc_log_set_debug_string function to set a regex
1807 string to match for debug output. Only the function names,
1808 or filenames matching the given debug string is actually
1809 printed. This way it is possible to filter out those debug
1810 strings that user is not interested in.
1812 Fixed a bug in silc_string_regexify.
1814 Affected files lib/silcutil/silclog.[ch], and
1815 lib/silcutil/unix/silcunixutil.c.
1817 * Changed the -d options in both server and Irssi SILC client
1818 to take the debug string as argument. Affected files
1819 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1821 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1823 * Added silc_hash_babbleprint to create a Bubble Babble
1824 Encoded fingerprint. The encoding is developed by Antti
1825 Huima (draft-huima-babble-01.txt), and it creates human
1826 readable strings out of binary data. Affected file
1827 lib/silccrypt/silchash.[ch].
1829 * Print the babble print now in addition of fingerprint as well
1830 in Irssi SILC client. Affected files are
1831 irssi/src/fe-common/silc/module-formats.[ch],
1832 irssi/src/fe-common/silc/core/client_ops.c.
1834 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1836 * Fixed a security problem found in SKE. The initiator's
1837 public key too is now added to the HASH hash value creation
1838 which is signed by the responder to create the SIGN value.
1839 This will prevent anyone in the middle to lie to the responder
1840 about the initiator's public key. If this is done now, the
1841 man in the middle will get caught. Updated the protocol
1844 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1846 * Better installation directory handling. Configure module
1847 paths and other paths automatically to example_silc* files
1848 in doc/. A patch by toma.
1850 * Fixed compiler warning from MPI library, and from SILC RNG.
1853 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1854 It can be configured with ./configure. A patch by toma.
1856 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1858 * Find correct make to use in prepare-clean. A patch by
1859 toma. Affected file prepare-clean.
1861 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1863 * Added irssi variables use_auto_addr, auto_bind_ip,
1864 auto_bind_port and auto_public_ip.
1866 * Changed the interface for silc_client_send_key_agreement
1867 in lib/silcclient/silcapi.h
1871 irssi/src/silc/core/silc-core.c
1873 lib/silcclient/silcapi.h
1874 irssi/src/silc/core/silc-channels.c
1875 lib/silcclient/client_keyagr.c
1878 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1880 * Added silc_pkcs_public_key_compare to compare two
1881 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1883 * Check that the client who set the founder mode on the
1884 channel is the same client that is giving the founder
1885 mode to itself. It is done by comparing the saved public
1886 key (it is saved even in the authentication is passphrase).
1887 Affected file silcd/command.c.
1889 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1891 * Do not process packet for disconnected socket connection.
1892 Affected file lib/silccore/silcpacket.c.
1894 * Process the DISCONNECT packet through scheduler in the
1895 client library. Affected file lib/silcclient/client.c.
1897 * Fixed the silc_client_packet_parse to not to increase
1898 the packet sequence number if the conn->sock and the
1899 current socket connection is not same. This can happen
1900 for example during key agreement when the conn includes
1901 multiple socket connections (listeners). Affected file
1902 lib/silcclient/client.c.
1904 * The sender of the file transfer request now provides also
1905 the pointer (listener) for the key exchange protocol. If
1906 the listener cannot be created then it sends empty key
1907 agreement and lets the receiver provide the listener.
1909 Added `local_ip' and `local_port' arguments to the
1910 silc_client_file_send. If they are provided they are used,
1911 if not then it will attempt to find local IP address, if
1912 not found or bind fails then the remote client will provide
1915 Affected files are lib/silcclient/client_ftp.c and
1916 lib/silcclient/silcapi.h.
1918 * Extended the FILE SEND command to support defining the
1919 local IP and port for key exchange listener. They are
1920 optional. Affected file irssi/src/silc/core/silc-servers.c.
1922 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1924 * Defined to WHOIS command reply the sending of fingerprint
1925 of the client's public key (if the proof of posession of the
1926 corresponding private key is verified by the server).
1927 Updated to the protocol specification.
1929 * Added support of receiving the client's public key's
1930 fingerprint in command reply in client library. Affected
1931 file is lib/silcclient/command_reply.c, and
1932 lib/silcclient/idlist.[ch].
1934 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1936 * Do not send over 128 chars long nickname to the server
1937 in NICK command. Affected file lib/silcclient/command.c.
1939 * Do not send over 256 chars long channel names to the server
1940 in JOIN command. Affected file lib/silcclient/command.c.
1942 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1944 * Assure that silc_server_close_connection cannot be called
1945 twice for same socket context. Affected file is
1948 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1950 * Send error message to application if opening file for
1951 writing during file transfer fails. Affected file is
1952 lib/silcclient/client_ftp.c.
1954 Remove all file transfer sessions for a client that we're
1955 removing from ID cache.
1957 Affected file is lib/silcclient/client_ftp.c.
1959 * Fixed silc_net_addr2bin to return correct address. Affected
1960 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1962 * Fixed file transfer session removing on signoff notify.
1963 Affected file irssi/src/silc/core/silc-servers.c.
1965 * Added the SilcClientFileError to be returned in the monitor
1966 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1967 Affected file lib/silcclient/silcapi.h.
1969 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1971 * Fixed a crash in silc_client_ftp_free_sessions and
1972 silc_client_ftp_session_free_client. Affected file
1973 lib/silcclient/client_ftp.c.
1975 * Added `disabled' field in the SilcChannelEntry in the server
1976 to indicate if the server entry is disabled. Affected file
1977 silcd/idlist.h, silcd/command[_reply].c.
1979 * SILC server adds now /var/run/silcd.pid everytime it is
1980 started. Affected file silcd/silcd.c.
1982 * Added silc_server_packet_send_clients to send a packet to
1983 the provided table of client entries. Affected file
1984 silcd/packet_send.[ch].
1986 * Fixed a crash in client resolving in client_prvmsg.c in
1987 client library. Affected file lib/silcclient/client_prvmsg.c.
1989 * Do not actually remove the client directly from ID cache
1990 during SERVER_SIGNOFF, but invalidate it. This way we
1991 preserve the WHOWAS info for the client. Affected file
1992 silcd/server_util.c.
1994 * Fixed SERVER_SIGNOFF notify handling in the server. The
1995 server is now able to process incoming SERVER_SIGNOFF notify
1996 for a server that it doesn't even know about. It will remove
1997 the clients provided in the notify. Affected file
1998 silcd/packet_receive.c.
2000 * Check for partial packet in data queue after every packet that
2001 was found from the queue. Return and wait for more data if
2002 there is partial data in queue. Affected file is
2003 lib/silccore/silcpacket.c.
2005 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2007 * Added SilcClietFileError enum to indicate error in
2008 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2009 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2010 Affected files lib/silcclient/silcapi.h and
2011 lib/silcclient/client_ftp.c.
2013 * Check that newsize in silc_buffer_realloc is larger than
2014 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2016 * Added better monitor of file transfers. It now monitors
2017 key agreement protocol during the file transfer too. Added
2018 error reporting too. Affected files
2019 irssi/src/silc/core/silc-servers.c,
2020 irssi/src/fe-common/silc/module-formats.[ch].
2022 * Wrote a help file for FILE command.
2024 * Added silc_rng_global_get_byte_fast to get not-so-secure
2025 random data as fast as possible. Random data is read from
2026 /dev/urandom if available and from the SILC RNG if not
2027 available. It is used in padding generation. Affected file
2028 lib/silccrypt/silcrng.[ch].
2030 * All packets in client library are now processed synchronously.
2031 Optimized packet processing a lot. Affected file
2032 lib/silcclient/client.c.
2034 * All server connection packets are processing synchronously
2035 now in server, to optimize packet processing. Affected file
2038 * Include files are installed now only in Toolkit distribution
2039 if make install is given. Affected files: all Makefile.am's.
2041 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2043 * Assure that silc_client_notify_by_server_resolve does not
2044 resolve the client information multiple times. If it cannot
2045 be found by the first it cannot be found at all. Affected
2046 file lib/silcclient/client_notify.c.
2048 * Fixed WHOWAS command reply calling. Affected file
2049 lib/silcclient/command_reply.c.
2051 * Removed all references to silc_idlist_get_client from the
2052 Irssi SILC client since that call is internal call used by
2053 the library. The Irssi SILC client will use now client
2054 retrieval functions found in silcapi.h.
2056 * Fixed a bug in resolving nickname info before sending
2057 private message. It used freed memory. Affected file
2058 irssi/src/silc/core/silc-servers.c.
2060 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2062 * Assure my_channels statistics cannot go negative in server.
2063 Affected files silcd/server.c, silcd/server_util.c.
2065 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2075 lib/sftp/sftp_fs_memory.c.
2077 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2079 * Added silc_net_localip to return local host's IP address.
2080 Affected file lib/silcutil/silcnet.[ch].
2082 * If key exchange or rekey protocol is active for a connection
2083 parse all packets syncronously since there might be packets
2084 in packet queue that we are not able to process without first
2085 processing packets before them. Affected file silcd/server,
2086 lib/silcclient/client.c.
2088 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2089 whether library should continue processing the packet.
2090 Affected file lib/silccore/silcpacket.h.
2092 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2093 SilcSFTPMonitorData to SFTP server to monitor various

2102 transmission. Affected file lib/silcclient/client_ftp.c,
2103 lib/silccilent/client.[ch].
2105 * Added new local command FILE to the Irssi SILC Client.
2106 It is used to perform the file transfer. It has subcommands
2107 SEND, RECEIVE, SHOW and CLOSE. Affected files
2108 irssi/src/silc/core/client_ops.c,
2109 irssi/src/silc/core/silc-server.[ch].

2118 * Renamed silc_file_read and silc_file_write to functions
2119 silc_file_readfile and silc_file_writefile. Added function
2120 silc_file_open and silc_file_close. Affected files
2121 lib/silcutil/silcutil.[ch].
2123 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2125 * Resolve the client info when received private message or
2126 channel message for a client which nickname we don't know.
2127 Affected files lib/silcclient/client_prvmsg.c and
2128 lib/silcclient/client_channel.c.
2130 * Do not crash in /KEY if client is not connected. Affected

2134 lib/silcclient/idlist.h.
2136 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2137 is incomplete and is being resolved, it won't be resolved
2140 Make sure also that USERS command reply does not resolve
2141 twice information. Affected file is
2142 lib/silcclient/command_reply.c.
2144 Make sure that silc_client_get_clients_by_list does not
2145 resolve twice same information.
2147 * Check for valid client->id in the silc_server_free_client_data.
2148 Affected file silcd/server.c.
2150 * Fixed /GETKEY nick@server not to crash if the server entry
2151 is not found. Affected file lib/silcclient/command.c.
2153 * Fixed the silc_server_check_cmode_rights to check the
2154 requested modes correctly. Affected file silcd/command.c.
2156 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2158 * Better checks for non-printable chars in nick added.
2159 Affected file silcd/command.c.
2161 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2163 * Call the silc_server_udpate_servers_by_server in the
2164 primary router that comes back online in the backup resuming
2165 protocol. Otherwise it routes packets wrong. Affected file
2166 silcd/server_util.[ch], silcd/server_backup.c.
2168 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2170 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2171 lib/silcutil/silcbuffmt.[ch].
2173 * Redefined the SILC packet header to include the padding
2174 length. Affected file lib/silccore/silcpacket.[ch].
2176 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2177 length for maximum padding up to 128 bytes). Affected
2178 file lib/silccore/silcpacket.h.
2180 * Removed all backwards support for old 0.5.x MAC thingies.
2181 The SILC packet header change makes it impossible to be
2182 backwards compatible.
2184 * Send the ENDING packet with timeout in the backup resuming
2185 protocol. This is to assure that all routers has connected
2186 to the primary router. Affected file silcd/server_backup.c.
2188 * Changed the RNG to take the first IV from random data. It
2189 used to take it from zero actually. Changed the RNG also
2190 to use /dev/urandom during session. /dev/random is used
2191 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2193 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2195 * Changed the SILC packet header to have the first two bytes
2196 (the packet length) encrypted. Affected files aroung the
2197 code tree, lib/silccore/silcpacket.[ch]. Removed the
2198 SilcPacketCheckDecrypt callback. It is not needed anymore
2199 since the silc_packet_receive_process will determine now
2200 whether the packet is normal or special.
2202 * Implemented the unidirectional MAC keys. Affected files
2203 lib/silcske/silcske.c, silcd/protocol.c and
2204 lib/silcclient/protocol.c.
2206 * Implemented the packet sequence number to the MAC computation.
2207 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2208 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2209 lib/silcclient/protocol.c.
2211 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2213 * Allow backup router to announce servers. All servers
2214 announced by backup router are added to the global list
2215 automatically. Update hte server's socket to our primary
2216 router also when backup router announces a server.
2217 Affected file silcd/packet_receive.c.
2219 * Do not update the client->router in the function
2220 silc_server_udpate_clients_by_server if the client is on
2221 global list. We might fail to find any specific server
2222 for locally connected clients and local cell clients. They
2223 should still use the `from' and not `to' as client->router.
2224 This fixes backup router resuming protocol. Affected file
2225 silcd/server_util.c.
2227 * Decrease channel statistics count only if the channel
2228 deletion worked. Affected files are silcd/server.c and
2229 silcd/server_util.c.
2231 * Added silc_server_update_servers_by_server to update origin
2232 of all server entries. Used during backup router protocol.
2233 Affected files silcd/server_util.[ch], silcd/server.c. and
2234 silcd/backup_router.c.
2236 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2237 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2238 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2239 lib/silccrypt/silchmac.c.
2241 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2243 * Assure that router cannot reroute the same channel message
2244 to the sender. Affected file silcd/packet_receive.c.
2246 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Made better checks that the channel message is not sent
2249 to the router it came from. Affected file is
2250 silcd/packet_send.c. Fixed memory leak too.
2252 * Announce informations for incoming router connection, but
2253 only after checking if it is replaced by backup router.
2254 Affected file silcd/packet_receive.c.
2256 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2258 * Fixed the backup resuming protocol to work in multiple
2259 router environment. Affected file silcd/server_backup.c.
2261 * Route packet only to one router in the function
2262 silc_server_packet_send_to_channel. Affected file is
2263 silcd/packet_send.c.
2265 * Fixed silc_server_send_notify_dest to set the broadcast
2266 flag. Fixed the silc_server_send_notify_topic to actually
2267 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2268 Affected file silcd/packet_send.c.
2270 * Changed the SFTP Filesystem interface. Changed the
2271 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2272 the filesystem operation function. The SilcSFTPFilesystem
2273 is now a context that is allocated by all filesystem allocation
2274 functions and it already includes the operations structure
2275 and filesystem specific context. It is given as argument
2276 now to the silc_sftp_server_start. This made the interface
2277 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2278 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2280 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * Changed the backup router adding and getting interfaces
2283 in the server. The router that will be replaced by the
2284 specified backup router is now sent as argument. Affected
2285 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2288 * Added silc_net_addr2bin_ne to return the binary form of
2289 the IP address in network byte order. Affected files
2290 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2292 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2294 * Check for existing server ID in silc_server_new_server
2295 and in silc_server_connect_to_router_final and remove the
2296 old entry if it exists. Affected file silcd/packet_receive.c,
2299 * Send the channel message always to only one router, either
2300 in upstream or downstream. Affected file is
2301 silcd/packet_send.c.
2303 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2305 * Wrote the definition of the backup resuming protocol to the
2306 protocol specification.
2308 * Removed one redundant channel key generation from normal
2309 server during joining procedure. Removed one redundant
2310 channel key sending from server to router during joining
2311 procedure. Affected file silcd/command.c.
2313 * Made minor bugfixes to the backup router resuming protocol.
2314 Affected file silcd/server_backup.c, server.c.
2316 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2318 * Added --disable-asm configuration option. Affected files
2319 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2322 * Implemented the backup resuming protocol that is used to
2323 resume the primary router position in the cell after the
2324 primary router comes back online. Affected files
2325 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2326 and silcd/server_util.[ch].
2328 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2330 * Sleep two (2) seconds after sending QUIT command to server.
2331 Affected file lib/silcclient/command.c.
2333 * Assure that if outgoing data buffer is pending do not force
2334 send any data. Affected file silcd/packet_send.c.
2336 * Assure that if outgoing data buffer is pending do not force
2337 send any data. Affected file lib/silcclient/client.c.
2339 * Implemented the backup router support when the primary router
2340 goes down. The servers and routers can now use the backup
2341 router as new primary router without loosing connectivity.
2343 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2345 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2346 in the server to indicate disabled entry. All data read
2347 from the connection will be ignored and no data is sent
2348 for entry that is disabled. Affected files are
2349 silcd/idlist.h, silcd/server.c.
2351 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2353 * Created SFTP client and server test programs in the
2354 lib/silcsftp/tests directory.
2356 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2358 * Implemented memory filesystem (virtual filesystem) for
2359 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2362 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * Implemented the SFTP (SSH File Transfer Protocol) to the
2365 lib/silcsftp. It includes SFTP client and SFTP server
2368 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2370 * Moved lib/silccore/silcprotocol.[ch] to the
2371 lib/silcutil library.
2373 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2374 take variable argument list pointer as argument. Affected
2375 file lib/silcutil/silcbuffmt.[ch].
2377 * Added silc_buffer_set function that is used to set data
2378 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2379 Affected file lib/silcutil/silcbuffer.h.
2381 * Changed various routines in the core library to use the new
2382 silc_buffer_set instead of allocating new buffer only for
2385 * Added 64-bit value formatting and unformatting support to the
2386 silc_buffer_[un]format routines. Affected file is
2387 lib/silcutil/silcbuffmt.[ch].
2389 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2390 to includes/bitmove.h.
2392 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2394 * Fixed channel user mode saving in client library. Affected
2395 file lib/silcclient/command[_reply].c.
2397 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Defined the file transfer to the SILC Protocol. Added
2400 new packet type SILC_PACKET_FTP and defined File Transfer
2401 Payload. The mandatory file transfer protocol is SFTP
2402 (SSH File Transfer Protocol). Affected file in addition
2403 of the internet draft is lib/silccore/silcpacket.h.
2405 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2406 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2407 is used as part of backup router protocol when the primary
2408 router of the cell is back online and wishes to resume
2409 the position as primary router.
2411 * Redefined the MAC generation keys in the protocol. The
2412 same key is not used anymore in both direction. Both
2413 direction will now use different keys for sending and
2414 receiving. This fixes a potential security flaw. This
2415 change causes incompatibilities in the protocol.
2417 * Redefined also the MAC computation from the packet.
2418 An packet sequence number is now added to the MAC
2419 computation. This prevents possible replay attacks against
2420 the protocol. This change too causes incompatibilities
2423 Added `sequence' field to the SilcPacketContext to hold
2424 the current sequence number for the packet.
2426 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2428 * Added `created' field to the SilcIDListData in the file
2429 silcd/idlist.h to indicate the time when the entry was
2432 * Added `created' field to the SilcChannelEntry too. Affected
2433 file silcd/idlist.h.
2435 * Added `creation_time' aguments to all the announcement functions
2436 in the server. If it is provided then only the entries that
2437 was created after the provided time frame are actually
2438 announced. Affected file silcd/server.[ch].
2440 * The protocol says that the Channel ID's IP address must be
2441 based on the router's IP address. Added check for this in
2442 the silc_server_new_channel when processing incoming New Channel
2443 Payload. Affected file silcd/packet_receive.c.
2445 * Print out the correct version with --version in SILC client.
2446 Affected file irssi/src/silc/core/silc-core.c.
2448 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2450 * Fixed WHOWAS command to check for completnes of the client
2451 entry always, not just when the command is coming from client.
2452 Affected file silcd/command.c.
2454 * Added new function silc_server_packet_queue_purge to purge the
2455 outgoing data queue to the network. After the function returns
2456 it is guaranteed that the outgoing packet queue is empty.
2457 Affected file silcd/packet_send.[ch].
2459 * Purge the outgoing packet queue in the rekey protocol's final
2460 callback to assure that all rekey packets go to the network
2461 before quitting the protocol. Affected file silcd/server.c.
2463 * Added silc_client_packet_queue_parse as similar function as
2464 in server to the client library. The affected file is
2465 lib/silcclient/client.c.
2467 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2469 * Splitted silcd/server.c and created silcd/server_util.[ch]
2470 for utility functions.
2472 * Added new socket flag SILC_SF_DISABLED to indicate that the
2473 connection is open but nothing can be sent to or received from
2474 the connection. Affected file lib/silcutil/silsockconn.[ch].
2475 The checking for disabled socket is checked in the low level
2476 silc_socket_write and silc_socket_read functions.
2478 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * Allow only nicknames and channel names that fits into the
2481 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2483 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2485 * When processing JOIN command reply in server check that if
2486 the channel exists in our global list we'll move it the local
2487 list. Affected file silcd/command_reply.c.
2489 * Fixed the check whether client is joined on the channel already
2490 in JOIN command. Affected file lib/silcclient/command.c.
2492 * Fixed the JOIN command reply to check whether the channel
2493 already exists. Affected file lib/silcclient/command_reply.c.
2495 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2497 * Added silc_ske_status_string to map the SKE error numbers
2498 to readable strings. The affected files are
2499 lib/silcske/silcske[_status].[ch].
2501 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2503 * Do not show the private channels on the WHOIS channel list
2504 as it is not allowed by the protocol. The affected file is
2507 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2509 * Assure that the packet length digged from the actual packet
2510 is something sensible in the silc_packet_decrypt_rest_special
2511 in lib/silccrypt/silcpacket.c.
2513 * Free and NULL the allocated pointer in silc_hmac_alloc if
2514 the HMAC allocation fails. The affected file is
2515 lib/silccrypt/silchmac.c.
2517 * Print the selected security properties to the log files in
2518 the server. Affected file silcd/protocol.c.
2520 * Add SKE's reference counter even if calling the completion
2521 callback manually. Otherwise it goes negative, although it
2522 does not cause any problems. The affected file is
2523 lib/silcske/silcske.c.
2525 * Remove the client entry with short timeout after giving the
2526 KILL command. Affected file lib/silcclient/command.c.
2528 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2529 case all found clients are already disconnected (WHOWAS would
2530 found them) in the server. Affected file silcd/command.c.
2532 * Update the last_receive (time of last data received) to be
2533 updated only when received private or channel message so that
2534 the idle time showed in WHOIS makes more sense.
2536 * Added boolean field `valid' in to the SilcClientEntry in the
2537 client library to indicate whether the entry is valid or not.
2538 This fixes the nickname change bug on channel when changing
2539 the nickname to be same than the old (like nick to Nick) the
2540 nickname formatter doesn't set the new nick anymore to Nick@host.
2541 Affected file lib/silcclient/idlist.[ch].
2543 * Now actually fixed the nickname changing on disconnection.
2544 Added new function silc_change_nick to the Irssi SILC Client.
2545 Affected file irssi/src/silc/core/client_ops.c,
2546 irssi/src/silc/core/silc-nicklist.[ch].
2548 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2550 * Check that the public key exists in the GETKEY command before
2551 trying to encode it. Affected file silcd/command.c.
2553 * Print some notifications on received public keys with GETKEY
2554 command in the Irssi SILC Client. Affected files are
2555 irssi/src/fe-common/silc/module-formats.[ch],
2556 irssi/src/silc/core/client_ops.c.
2558 * Use IDENTIFY command to resolve the server information in the
2559 GETKEY command instead of INFO command. Affected file
2560 lib/silcclient/command.c.
2562 * All command reply functions in the client library now calls
2563 the pending command reply callbacks even if an error has
2564 occurred. The server has done this a long time and now it was
2565 time to move the client library to this as well. Now all
2566 errors can be delivered back to the pending command reply
2567 callbacks if necessary. Affected files are
2568 lib/silcclient/command[_reply].[ch].
2570 * Change the nickname on disconnection back to the username
2571 because in reconnect the server will enforce it to it anyway.
2572 Affected file irssi/src/silc/core/silc-servers.c.
2574 * Fixed a config file parsing bug in the Irssi SILC client.
2575 Affected file irssi/src/silc/core/clientconfig.c.
2577 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2579 * When printing the channel mode on JOIN, verify that the
2580 channel key and channel's HMAC are valid. Affected file
2581 irssi/src/silc/core/client_ops.c.
2583 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2585 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2586 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2587 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2589 * Removed channel key rekey task deleting from the function
2590 silc_server_save_channel_key. Affected file silcd/server.c.
2591 Added explicit timeout task context instead that is used to
2592 delete the task if we are registering a new task before the
2593 new task has elapsed.
2595 * When channel key rekey occurs the client library now saves
2596 the old channel key for a short period of time (10 seconds) and
2597 is able to use it in case some is still sending channel
2598 messages encrypted with the old key after the rekey. Affected
2599 file lib/silcclient/[idlist.h|client_channel.c].
2601 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2603 * Added check to the silc_server_new_id_real to not accept
2604 new ID if it is the sender's own ID. Affected file is
2605 silcd/packet_receive.c.
2607 * Assure that we do not announce ourself or the one we've
2608 sending our announcements when we're router and are announcing
2609 servers to our primary router. Affected file silcd/server.c.
2611 * Fixed silc_server_command_identify_check_client to assemble
2612 correct WHOIS packet. It send corrupted WHOIS packet and
2613 caused problem with router to router connections. Affected
2614 file silcd/command.c.
2616 Fixed also silc_server_command_whois_check the same way
2617 as for the IDENTIFY command.
2619 * Added new SilcIDListStatus to the server in the SilcIDListData
2620 structure. The status now includes the current status of
2621 the entry (like registered, resolved etc.). Affected file
2622 silcd/idlist.[ch]. Defined a bunch of different status types
2623 as well. This replaced the old boolean registered field as well.
2625 Added resolve_cmd_ident field to the SilcClientEntry structure
2626 too so that if the entry is for example being resolved so
2627 another command may attach to the same pending command reply
2628 without requiring to resolve the same entry again. This concept
2629 should optimize the WHOIS and the IDENTIFY resolving under
2630 heavy load by taking away unnecessary resolving for entries
2631 that are being resolved already.
2633 Added support for adding multiple pending commands for one
2634 command idenfier. Affected file silcd/command[_reply].[ch].
2636 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2637 before deleting the data. Otherwise the hash table will have
2638 freed data in comparison functions. Affected file is
2639 silcd/command_reply.c.
2641 * Fixed silc_idlist_replace_client_id to add the new entry to
2642 the cache with NULL nickname. Otherwise there will be invalid
2643 memory as the nickname after the nickname is freed. Affected
2644 file silcd/packet_receive.c.
2646 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2647 saved into wrong slots because the previous number of entries
2648 was not taken into account. Affected file silcd/idlist.c.
2649 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2651 * If we are router and we receive JOIN notify to a channel that
2652 does not have any users then notified client is marked as the
2653 channel founder, as it is it. The affected file is
2654 silcd/packet_receive.c
2656 * Added to the extended hash table API's table_del_*ext functions
2657 the destructor as argument too, so that the caller can decide
2658 which destructor to use or whether to use destructor at all.
2659 Affected file lib/silcutil/silchashtable.[ch].
2661 * Fixed ID Cache purging. It actually deleted the entries from
2662 the hash table after the data was freed. The hash table ended
2663 up comparing freed memory. The affected file is
2664 lib/silccore/silcidcache.c.
2666 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * Fixed Irssi SILC client's KILL command's HELP syntax.
2670 * The USERS command now resolves the detailed user information
2671 if the userinfo field is missing. Affected file is
2672 lib/silcclient/command_reply.c.
2674 * Do not print error in silc_file_read if the read file does
2675 not exist. Just silently return NULL. Affected file is
2676 lib/silcutil/silcutil.c.
2678 * Fixed the silc_log_output to not wine about NULL filename
2679 and to not create some bogus " " filename. Affected file is
2680 lib/silcutil/silclog.c.
2682 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2684 * Fixed various printing bugs on the user interface in the
2685 Irssi SILC Client. Minor changes that were forgotten from
2688 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * Fixed the configure.in.pre and the compilation and distribution
2691 environment to support the new autoconf 2.52. That version is
2692 now required to compile the CVS trunk.
2694 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2697 to generally parse user@fqdn format strings. Affected file
2698 lib/silcutil/silcutil.c.
2700 * Added nickname_format and nickname_force_format fields to the
2701 SilcClientParams structure. The first one defines the format
2702 for the nicknames that the library will enforce if the receives
2703 multiple same nicknames. The second one is boolean value and
2704 can be used to force the library to always enforce the format
2705 to the nicknames regardles whether there are multiple nicknames
2706 or not. This configurable formatting was employed to flexibly
2707 support accessing multiple nicknames from the user interface.
2708 The userinterface can now set the nicknames to what ever format
2709 they prefer. Affected file lib/silcclient/silcapi.h.
2711 Added function silc_client_nickname_format to the file
2712 lib/silcclient/idlist.c. It performs the nickname formatting.
2714 Added new field `hostname´ to the SilcClientEntry context.
2715 It holds the hostname of the client. Affected file is
2716 lib/silcclient/idlist.h.
2718 * Irssi SILC Client sets the nicknames in nick@hostn format.
2719 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2720 irssi/src/silc/core/silc-core.c.
2722 The WHOIS printing now also shows both the real nickname and
2723 the formatted nickname so that user knows how to access the
2724 user if there are multiple same nicknames cached. Affected
2725 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2726 printing formatting too to take the hostname now as a separate
2727 argument. The Affected file is
2728 irssi/src/fe-common/silc/modules-formats.[ch].
2730 * Changed the silc_client_get_clients_local to accept the formatted
2731 nickname as argument. It accepts the real nickname too but the
2732 formatted nickname can be used to find the true entry from
2733 multiple entries. Affected file lib/silcclient/silcapi.h and
2734 lib/silcclient/idlist.c.
2736 * Added nickname_format_parse field to the SilcClientParams.
2737 It is a callback function provided by the application to parse
2738 the nickname out of the formatted nickname string. The library
2739 calls it to get the nickname from the formatted string. Since
2740 the application generally knows better the format of the nickname
2741 string it parses it instead of the library, even though library
2742 encodes the formatted string. If the callback function is not
2743 provided then the library will use the string as is. The
2744 affected file is lib/silcclient/silcapi.h.
2746 * All the nickname strings passed to the client library in
2747 commands are now expected to be formatted nickname strings.
2748 If the command does not support the formatted nickname string
2749 it will assume that the sent string is the actual nickname.
2750 Affected file lib/silcclient/command.c.
2752 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2754 * Added public key authentication support to OPER and SILCOPER
2755 commands in the client library. Affected file is
2756 lib/silcclient/command.c.
2758 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2760 * Changed the get_auth_methdod client operation to be asynchronous.
2761 It can be async if the application resolves the authentication
2762 method from the server during the negotiation. Added new
2763 SilcGetAuthMeth completion callback that the application will
2764 call after resolving the authentication method.
2766 Added function silc_client_request_authentication_method that
2767 the application can use to resolve the authentication method
2768 from the server. Added also SilcConnectionAuthRequest callback
2769 that the library will call after the server has replied. The
2770 application can call this function if it does not know the
2771 current authentication method.
2773 Affected files are lib/silcclient/client.c and
2774 lib/silcclient/silcapi.h.
2776 * The Irssi SILC client now automatically resolves the authentication
2777 method incase any configuration information is not present (and
2778 currently there never is). The affected file is
2779 irssi/src/silc/core/client_ops.c.
2781 * Fixed public key authentication from the client library.
2782 Affected file lib/silcclient/protocol.c. Changed also the
2783 protocol specification about the public key authentication in
2784 the connection authentication protocol. The actual data to be
2785 signed is now computed with a hash function before signing.
2787 * Fixed the public key authentication from the server as well.
2788 Affected file silcd/protocol.c.
2790 * Removed the mlock()'s from the memory allocation routines.
2791 Affected file lib/silcutil/silcmemory.c. The ./configure does
2792 not check anymore for the mlock(). Affected file is
2795 * Fixed USERS command in server to allow the execution of the
2796 command for private and secret channels if the client sending
2797 the command is on the channel. Affected file silcd/command.c.
2799 * Fixed silc_client_get_clients_local to return the clients
2800 count correctly. It could return wrong value. Affected file
2801 lib/silcclient/idlist.c.
2803 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2805 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2806 types. The assembler optimizations seemed not to like 64-bit
2807 data types. The assmebler optimizations thus are now enabled
2808 also for BSD systems as opposed to only enable them for Linux.
2810 * Do not check for threads at all on BSD systems. Affected
2811 file configure.in.pre.
2813 * Removed -n and -h options from the Irssi SILC Client since
2814 they are not used in silc.
2816 * Fixed the prime generation to assure that the first digit
2817 of the generated random number is not zero since our conversion
2818 routines does not like number strings that starts with zero
2819 digit. If zero digit is seen the random number is regenerated.
2820 This caused some corrupted RSA keys when the zero first digit
2821 was met. Affected file lib/silcmath/silcprimegen.c.
2823 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2825 * Fixed WIN32 configuration in the ./configure script.
2826 Fixed to include xti.h on environments that has it.
2827 Patches by Carsten Ilchmann and andrew.
2829 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2831 * Changed the silc_id_create_client_id to be collision
2832 resistant. It is now assured that there cannot be created
2833 two same client ID's. I suspect that some weird bugs in
2834 the server were actually caused by duplicate Client IDs.
2835 Affected file silcd/serverid.[ch]. A router receiving
2836 new ID now also assures and informs the sending server
2837 if the ID caused collision.
2839 * Changed the silc_id_create_channel_id to also assure that
2840 there are no collisions.
2842 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2844 * Statement about ignoring the Mutual Authentication flag when
2845 performing rekey with PFS was a bit misleading. It is ignored
2846 if it was set in the initial negotiation, it cannot be even
2847 set in the rekey. Fixed in the ke-auth draft. Started the
2848 new versions of the protocol drafts in the doc/.
2850 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2852 * Fixed a bug in silc_client_command_identify_save when saving
2853 new channel information. The channel name was no duplicated
2854 and caused crash on exit. Affected file is
2855 lib/silcclient/command_reply.c.
2857 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2859 * Fixed the getkey command handling in the server. Send just
2860 empty OK reply to the sender if the key could not be fetched
2861 (but everything else was ok, like the key just was not available).
2862 Changed the public key parameter to optional in the protocol
2863 specs so that empty OK reply can be sent. Affected file
2866 Added a message to Irssi SILC client to tell to user if the
2867 server did not return a public key.
2869 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2871 * Fixed a channel key regeneration bug. It registered new
2872 timeout tasks exponentially until all system resources were
2873 used. Affected file silcd/server.c.
2875 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2877 * Added the SILC Document generator to the scripts/silcdoc.
2878 It can be used to generate the Toolkit Reference Manual out
2879 of the source tree. Internally it will also use the RoboDoc
2880 generator now imported in util/robodoc.
2882 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2884 * Added couple of return's in rekey protocol if error orccurred
2885 during the protocol. The execution must be terminated.
2886 Affected file silcd/protocol.c. Also, terminate the protocol
2887 always with timeout.
2889 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2891 * The client's Client ID was created initally from the wrong
2892 nickname (it could have been in format nick@host) in the
2893 silc_server_new_client. Affected file silcd/packet_receive.c
2895 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2897 * Added some SILC_LOG_ERROR's to various error conditions
2898 if client could not be added to ID cache. Affected files
2899 silcd/packet_receive.c and silcd/server.c.
2901 * When client's sock->user_data is freed, NULL also the
2902 client->router and client->connection pointers. Added check
2903 for these pointers being NULL to various places around the
2904 code. Affected file silcd/server.c.
2906 * Added client->data.registered == TRUE checks to various
2907 places around the code to assure that unregistered client's
2908 are not handled when it is not allowed. Affected file
2911 * Added `bool registered' fields to all
2912 silc_idlist_[server|client]_get_* routines to indicate whether
2913 the fetched client needs to be registered or not. Affected
2914 file silcd/idlist.[ch].
2916 * Add your own entry as registered to the ID cache in the
2917 server. Affected file server.c.
2919 * Fixed a bug in silc_server_new_server. The SilcServer was
2920 set as the new server's context instead of SilcServerEntry.
2921 This naturally caused some weird bugs.
2923 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2925 * Do not delete the channel rekey task when adding it
2926 for in silc_server_create_channel_key.
2928 * Changed the silc_server_create_channel_key to return
2929 TRUE or FALSE to indicate the success of the channel key
2932 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2934 * Fixed MSVC++ project files and added missing files to
2935 Makefiles under win32/.
2937 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2939 * Do not add TCP_NODELAY flag if the operating system
2940 does not have it defined. Affected files are
2941 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2943 * Fixed buffer overflow from Irssi SILC Client. Affected
2944 file irssi/src/fe-common/core/themes.c.
2946 * Fixed double free in client library in the file
2947 lib/silcclient/client.c when disconnecting from server.
2949 * Applied double free patch from cras to Irssi SILC client.
2950 Affected files irssi/src/core/[modules/expandos].c
2952 * Fixed the disconnection handling to Irssi SILC Client.
2953 The application must call silc_client_close_connection
2954 in ops->connect client operation in case of failure of
2955 the connection. Affected file is
2956 irssi/src/silc/core/client_ops.c.
2958 * Do not set sock->protocol to NULL in the function
2959 silc_client_close_connection after executing the protocol's
2960 final callback since the sock might not be valid anymore.
2961 Affected file lib/silcclient/client.c.
2963 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2965 * Do not enable SILC_THREADS if the linking with libpthread
2966 did not happen. Affected file configure.in.pre.
2968 * Added notion to protocol specification that server must
2969 verify the sent authentication payload with CMODE when
2970 setting the channel founder key. Implemented it to the
2971 server. Affected file silcd/command.c.
2973 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2975 * Added _EXTRA_DIST SILC distribution variable to the
2976 distributions file. It is used to conditionally add extra
2977 files or directories to the specific distribution. Affected
2978 files ./prepare, Makefile.am.pre and distributions.
2980 Removed the `_' from the start of the distribution names.
2983 * Added README.WIN32 for instructions to compile the Toolkit
2986 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2988 * Fixed a double free in disconnection in the server. Affected
2989 file is silcd/server.c.
2991 * Fixed the lib/silcske/groups.c to work now also with GMP
2992 MP library. The string conversion did not work when using
2993 specific base and the base is indicated in the string as well.
2995 * Created win32/ directory which now includes MSVC++ specific
2996 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2997 It will appear only in the toolkit distribution
2999 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * Changed the key material distribution function in case when
3002 the hash output is too short. The data is now concatenated
3003 a bit differently than it used to. Made the change to the
3004 SKE protocol specification.
3006 * Added better GMP detection to configure.in.pre. A patch
3009 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3011 * Fixed a minor bug in SKE that might cause some problem on
3012 some platforms. Affected file lib/silcske/silcske.c.
3014 * Added the cookie checking for initiator in the SKE. It checks
3015 that the responder returns the sent cookie unmodified. The
3016 affected file is lib/silcske/silcske.c. Added new SKE
3017 error type INVALID_COOKIE that can be sent during the
3018 negotiation. Fixed some memory leaks as well.
3020 * Added the "invalid cookie" error message to Irssi SILC client's
3023 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3025 * Added `task_max' field to the SilcClientParams to indicate
3026 the maximum tasks the scheduler can handle. If set to zero,
3027 default values are used. Affected file lib/silcclient/silcapi.h.
3029 * Fixed memory leaks in silc_client_close_connection. Affected
3030 file lib/silcclient/client.c.
3032 * Added silc_client_del_client_entry to client library to free
3033 all memory of given client entry. Affected file is
3034 lib/silcclient/idlist.[ch].
3036 * Added new functions silc_client_del_channel and
3037 silc_client_del_server to delete channel and server entries.
3038 Affected file lib/silcclient/[silcapi.h/idlist.c].
3040 * Removed silc_client_del_client_by_id from silcapi.h.
3042 * Fixed the INFO command to return the server's own info
3043 correctly when querying by Server ID. Affected file is
3046 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3048 * Removed the non-blocking settings in WIN32 code in the
3049 silc_sock_[read/write] and added SleepEx instead. Affected
3050 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3051 of input data is now checked with FIONREAD and ioctlsocket.
3053 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3055 * Call silc_schedule_task_del_by_context in the
3056 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3057 Affected file lib/silccore/silcprotocol.c.
3059 * Call silc_protocol_cancel for active protocols in the
3060 silc_server_close_connection if the funtion
3061 silc_server_free_sock_user_data has not been called.
3062 Affected file silcd/server.c.
3064 * Generic tasks cannot be deleted using the del_by_fd
3065 task deleting function since generic tasks does not match
3066 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3068 * Added a notion to SILCOPER help file that the SILCOPER works
3069 only on router server, not on normal server.
3071 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3073 * Added for WIN32 support for the new scheduler as well.
3074 Affected file lib/silcutil/win32/silcwin32schedule.c.
3076 * Fixed the SHA1 implementation to work on various platforms.
3078 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3080 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3081 API. It is part of the scheduler now. Everything else is
3082 as previously but some functions has changed their names.
3083 Checkout the lib/silcutil/silcschedule.h for the interface.
3084 Updated all applications to use the new interface. Affected
3085 files are lib/silcutil/silcschedule.[ch].
3087 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3089 * Found a bug in the SKE implementation. The HASH value,
3090 specified by the protocol, was not computed correctly. The
3091 public key of the responder was not added to the computation
3092 even though it is mandatory. Affected file lib/silcske/silcske.c.
3093 This unfortunately causes incompatibilities with older
3094 clients and servers.
3096 * Added WIN32 specific network init and uninit functions:
3097 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3098 the Winsock2. Affected file lib/silcutil/silcnet.h and
3099 lib/silcutil/win32/silcwin32net.c.
3101 * Set the socket always to nonblocking mode on WIN32 after
3102 reading data or writing data. Affected file is
3103 lib/silcutil/win32/silcwin32sockconn.c.
3105 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3107 * Fixed various compilation problems under WIN32. Affected
3108 files lib/silcutil/win32/silcwin32thread.c and
3109 lib/silcutil/win32/silcwin32schedule.c.
3111 * Removed all _internal.h #includes from public header
3112 files. Internal headers must never be included from
3115 Removed also the lib/silcske/payload_internal.h file.
3117 * All include files that may be needed (public and some others
3118 included by the public headers) by application developers are
3119 now copied to the ./includes directory. It does not copy any
3120 internal headers. Affected file Makefile.defines.pre and all
3121 Makefile.am's under lib/ and subdirs.
3123 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3125 * Do not change the ~/.silc directory's permissions automatically.
3126 Affected file irssi/src/silc/core/clientutil.c.
3128 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3130 * Do not cancel the protocol in silc_server_close_connection
3131 it might cause recursion. Now cancelled in the function
3132 silc_server_free_sock_user_data. Affected file silcd/server.c.
3134 * Fixed the silc_server_remove_clients_by_server to regenerate
3135 the channel keys correctly finally. Added also new function
3136 silc_server_remove_clients_channels to actually do it.
3137 Affected file silcd/server.c.
3139 * Fixed the silc_server_new_channel to not crash by giving
3140 wrong router to the new channel. Affected file is
3141 silcd/packet_receive.c.
3143 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3145 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3146 which is given as argument to the silc_client_alloc now.
3147 It can be used to configure the client and set various parameters
3148 that affect the function of the client.
3150 * The USERS command in server did not check whether the channel
3151 is private or secret. Affected file silcd/command.c.
3153 * Added new argument to the USERS command in protocol specification.
3154 The USERS command now can take the channel name as argument
3155 as well. Added support for this in client and server and
3156 updated the protocol specs.
3158 * Completed the GETKEY command in client. It can be now used
3159 to fetch also servers public key not only some clients.
3160 Affected files lib/silcclient/command[_reply].c.
3162 * Added silc_client_get_server to return server entry by the
3163 server name. Affected files lib/silcclient/silcapi.h and
3166 * Redefined the IDENTIFY command in protocol specification to be
3167 more generic. It now can be used to query information about
3168 any entity in the SILC Network, including clients, servers and
3169 channels. The query may be based either the entity's name
3170 or the ID. Added support for this in both client and server.
3172 Affected files silcd/command.c and lib/silcclient/command.c
3173 and command_reply.c.
3175 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3176 the _from_client and _from_server functions. Affected file
3179 * Added silc_client_get_channel_by_id_resolve to the file
3180 lib/silcclient/silcapi.h to resolve channel information by
3181 its ID. Added also silc_client_get_channel_by_id that
3182 does not resolve it from the server.
3184 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3186 * Added SilcServerEntry context into the client library
3187 to represent one server. The INFO command now allocates
3188 these to save the resolved server info. For now on the
3189 client library will also keep information about servers,
3190 connected and resolved with INFO.
3192 The INFO command now allocates the SilcServerEntry context
3193 and saves the server info there. The COMMAND_REPLY in
3194 the INFO now returns the parameters to application in
3195 same order as defined in the protocol specification.
3197 The entries are cached in the client->server_cache.
3199 * The INFO command is now issued after received the Client ID
3200 from the server. Affected file lib/silcclient/client.c.
3202 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3203 to the application as the mode changer might be server.
3204 It is guaranteed that NULL is not returned anymore to the
3205 application. Affected file lib/silcclient/client_notify.c.
3207 The ID Type is now also passed to the application so that
3208 it can check whether the returned entry is SilcClientEntry
3211 Added new function silc_client_get_server_by_id to return
3212 the server entry by ID. Affected files are the
3213 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3215 * Do not create the channel in the Irssi SILC Client when issuing
3216 the JOIN command but when received the sucessful JOIN command
3217 reply. Otherwise the channel might get created even though we
3218 could not join it. The Affected file is
3219 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3221 * Fixed a channel joining bug in router. The router must also
3222 check the channel modes, invite and ban lists etc. when serving
3223 the JOIN command sent by normal server. Affected file is
3224 silcd/command.c. The router now resolves the client's
3225 information from the server who sent the JOIN command if it
3226 does not know it, and processes the JOIN command only after
3229 * Changed the SilcCommandCb to take new argument; void *context2.
3230 Affected file lib/silccore/silccommand.h
3232 The second argument in the command callbacks in the server now
3233 includes the SilcServerCommandReplyContext if the command was
3234 called as pending command callback from the command reply.
3235 Otherwise it is NULL. When called as pending the status of the
3236 command reply will be checked and if it was erronous the
3237 error will be sent to the original sender of the command.
3238 This way the client always receives the error messages even
3239 though the server was actually the one who received the error
3240 when it resent the command to router, for example. Affected
3241 files silcd/command[_reply].[ch].
3243 * Fixed sending WHOWAS command's error message to client if
3244 the requested client could not be found. It was missing.
3247 * Changed the CMODE and CUMODE commands reply arguments in the
3248 protocol specification. The Channel ID is now sent in both
3249 of the commands to identify the channel. Implemented this
3250 new feature to the client and server. Affected files
3251 lib/silcclient/command_reply.c and silcd/command.c.
3253 * Made better checks for invite and ban lists in the JOIN
3254 command in server. Affected file silcd/command.c.
3256 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3258 * The server now performs the incoming host IP/DNS lookup
3259 using the silc_socket_host_lookup and thus does not block
3260 the server anymore. Affected file silcd/server.c.
3262 * Completed the multi-thread support for SILC Scheduler in
3263 the lib/silcutil/silcschedule.c.
3265 * Fixed the configure.in.pre to detect the pthread correctly
3268 * Fixed a deadlock in silc_task_queue_wakeup in the file
3269 lib/silcutil/silctask.c.
3271 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3273 * Added new function silc_schedule_wakeup that is used in
3274 multi-threaded environment to wakeup the main thread's
3275 schduler. It needs to be used when a thread adds a new task
3276 or removes a task from task queues. After waking up, the
3277 scheduler will detect the task queue changes. If threads
3278 support is not compiled in this function has no effect.
3279 Implemented the wakeup mechanism to both Unix and WIN32
3280 systems. Affected files are lib/silcutil/silcschedule.[ch],
3281 lib/silcutil/unix/silcunixschedule.c and the
3282 lib/silcutil/win32/silcwin32schedule.c.
3284 * Added new function silc_task_queue_wakeup to wakeup the
3285 scheduler by the specified task queue. Affected file
3286 lib/silcutil/silctask.[ch].
3288 * The silc_socket_host_lookup_start now wakes up the scheduler
3289 after adding the timeout task. Affected file is
3290 lib/silcutil/silcsockconn.c.
3292 * The silc_socket_host_lookup is synchronous now if the threads
3293 support is not compiled in. However, the callback is still
3294 called asyncronously through the scheduler, anyway. Affected
3295 file lib/silcutil/silcsockconn.c.
3297 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3299 * Added new function silc_socket_host_lookup to perform
3300 asynchronous IP and FQDN lookups for the socket connection.
3301 Affected files lib/silcutil/silcsockconn.[ch].
3303 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3305 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3306 that may or may not compile the mutex support in.
3308 Changed the silc_mutex_alloc interface. It allocates the
3309 mutex now to the sent pointer and returns TRUE or FALSE.
3311 Affected file lib/silcutil/silcmutex.h.
3313 * Wrote the SILC Task Queue interface to support multi-threads.
3314 Affected file lib/silcutil/silctask.[ch].
3316 * Wrote the SILC Scheduler to support multi-threads. Affected
3317 file lib/silcutil/silcschedule.c.
3319 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3321 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3322 in lib/silcutil/win32/.
3324 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3326 * Defined SILC Mutex API and SILC Thread API and implemented
3327 them for Unix. Affected files are
3328 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3329 lib/silcutil/unix/silcunixmutex.c and
3330 lib/silcutil/unix/silcunixthread.c.
3332 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3334 * Fixed the silc_server_remove_clients_by_server's channel
3335 key re-generation. The hash table handling was incorrect
3336 and would not work with many channels. Affected file is
3339 * Fixed some memory leaks around the server code.
3341 * Rewrote the silc_server_get_users_on_channel to support IPv6
3342 based Client ID's. Affected file silcd/server.c.
3344 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3345 specification. However, a separate document must be written
3346 to define the detailed signing procedure and the payload
3347 associated with the flag. Defined the flag to the
3348 lib/silccore/silcchannel.h as well.
3350 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3352 * Changed the dynamic tables to static size tables in the
3353 lib/silccrypt/silchmac.c.
3355 * Removed GCC dependencies from the code. A patch by cras.
3357 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3359 * Do not show the error "Error receiving packet bla bla"
3360 in server if it really was not an error (-2 means that reading
3361 is pending). Affected file silcd/server.c.
3363 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3365 * Fixed a possible crash in silc_server_remove_clients_by_server
3366 in silcd/server.c. Fixed there also some memory leaks.
3368 * Fixed the silc_idlist_replace_client_id. It could replace
3369 wrong key in the hash table. Affected file silcd/idlist.c.
3371 * Do not check whether there are global users on the channel
3372 if the channel->global_users is FALSE. Affected functions
3373 silc_server_remove_from_one_channel and
3374 silc_server_remove_from_channels in silcd/server.c. Also,
3375 do not check if the removed client is local as we can be
3376 sure that global client was not removed from the channel
3377 and checking for global users is not needed.
3379 * The silc_server_remove_clients_by_server now re-generates
3380 the channel keys correctly for those channels that had
3381 clients removed from them. Affected file silcd/server.c.
3383 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3385 * Found the reason of random crashes in the server. We weren't
3386 ignoring the SIGPIPE signal (which can be sent in write())
3387 and it crashed the server. Affected file silcd/silcd.c.
3389 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3391 * Assure that sock->user_data is not NULL in the function
3392 silc_server_packet_send in silcd/packet_send.c.
3394 * Disconnect the remote connection if it could not be added
3395 to any ID lists in the server. The affected file is
3398 * Check in silc_server_packet_send[_real/dest] that the
3399 socket is not disconnecting and ignore the data if it is.
3400 Affected file silcd/packet_send.c.
3402 * Define inline to __inline on native WIN32 compilation.
3403 Affected file includes/silcwin32.h.
3405 * Added some explicit type casts for inline code since MSVC
3406 require them. Affected files lib/silcutil/silcbuffer.h,
3407 lib/trq/silcdlist.h and lib/trq/silclist.h.
3409 * Print warning in log files from now on if the packet
3410 decryption fails. Affected file silcd/server.c.
3412 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3414 * Changed the `say' client operation's interface to accept
3415 new `type' argument to indicate the type of the message sent
3416 by the library. The application may filter the library's
3417 messages according the type. The affected file is the
3418 lib/silcclient/silcapi.h.
3420 * Added two new functions to lib/silcclient/silcapi.h:
3421 silc_client_del_client and silc_client_del_client_by_id.
3422 Affected file lib/silcclient/idlist.c.
3424 * Moved the clientincludes.h from includes/ to silc/ and
3425 serverincludes.h from includes/ to silcd/.
3427 * The modes for the CMODE and CUMODE are now passed as
3428 uint32 for application with COMMAND_REPLY. The affected
3429 file is lib/silcclient/command_reply.c.
3431 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3433 * /WHOIS without arguments shows client's own information.
3434 Affected file lib/silcclient/command.c.
3436 * Changed PING to not accept any arguments. The specs
3437 says that client can ping only the connected server so
3438 requiring an argument is not needed. Affected file is
3439 lib/silcclient/command.c.
3441 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3443 * Fixed a fatal bug in private message sending and reception
3444 encryption and decryption when using private message keys.
3445 The implementation was incorrect and did not follow the
3446 specification. It causd that some of the message were
3447 lost since it did not use the sending and receiving keys
3448 as the protocol suggests. This has been fixed and will cause
3449 incompatibilities with older clients when sending private
3450 message encrypted with private message keys. Affected files
3451 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3452 and various other in Irssi SILC Client.
3454 Added `responder' boolean argument to the functions
3455 silc_client_add_private_message_key[_ske] to indicate when
3456 the key is added as responder or initiator of the key
3459 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3461 * Removed the silc_ske_check_version function and created
3462 a SilcSKECheckVersion callback. Added also a function
3463 silc_ske_set_callbacks that is now used to set all SKE
3464 callbacks. The callback functions are not given to
3465 the SKE functions anymore, but this function is used to
3468 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3470 * Added `silc_version' argument to the silc_client_alloc
3471 to define the version of the application for the library.
3472 The library will use the version string to compare it
3473 against the remote host's (usually a server) version
3474 string. Affected file lib/silcclient/silcapi.h
3476 * Added the KE protocol context to Key Agreement context
3477 in client library so that we can abort the SKE if it
3478 is in process when we get timeout. Affected file is
3479 lib/silcclient/client_keyagr.c.
3481 * Do not resolve the client ID forever if it returns in the
3482 first time that such client does not exist. This was done
3483 for example with private message. Affected file is
3484 lib/silcclient/client_prvmsg.c.
3486 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3488 * Do not add regex.h for WIN32. The affected file
3489 includes/silcincludes.h.
3491 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3492 not work yet 100%. It generates the DLL's automatically
3493 when compiling with --with-win32 under cygwin.
3495 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3497 * lib/contrib/regex.c is not compiled on WIN32.
3499 * Added silc_net_get_socket_opt function to the
3500 lib/silcutil/silcnet.h.
3502 * Added includes/silcwin32.h for WIN32 specific includes
3505 * Do not use ptime structure or any of the posix process
3506 functions on WIN32 in lib/silccrypt/silrng.c.
3508 * Added silc_gettimeofday to provide generic function
3509 for struct timeval on all platforms. Added the function
3510 to lib/silcutil/silcutil.h.
3512 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3514 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3515 library as they clearly belong there. As a plus side we
3516 can make the actual socket connection routines platform
3519 Added also new generic function silc_socket_read and
3520 silc_socket_write (that used to be silc_packet_[read/write].
3521 The implementation of these are platform specific.
3523 * Added WIN32 specific routines of silc_socket_[read/write]
3524 to lib/silcutil/win32/silcwin32sockconn.c.
3526 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3528 * Added preliminary support for native WIN32 compilation under
3529 cygwin (using the -mno-cygwin option for GCC) to the
3530 ./configure.in.pre. The --with-win32 now prepares the
3531 compilation for native WIN32.
3533 * Rewrote the SILC Scheduler interface in the file
3534 lib/silcutil/silcschedule.h. The scheduler is now context
3535 based and does not have anymore any global static scheduler.
3536 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3537 and created lib/silcutil/win32 directory for WIN32 based
3540 * Added Unix specific network routines to the
3541 lib/silcutil/unix/silcunixnet.c and the old
3542 lib/silcutil/silcnet.c includes now only generic routines.
3544 Added WIN32 specific network routines to the
3545 lib/silcutil/win32/silcwin32net.c.
3547 * Added Unix specific utility functions from the
3548 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3550 * Added WIN32 SILC Scheduler to the file
3551 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3554 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3556 * Do not handle JOIN notify in the server if the target client
3557 is not registered (idata->registered == FALSE). The affected
3558 file is silcd/packet_receive.c.
3560 * Update the nickrec->founder in event_cumode in the Irssi SILC
3561 client. Affected file irssi/src/silc/core/silc-channels.c.
3563 * Fixed the CUMODE_CHANGE notify handling in the server when
3564 server and router are announcing their clients on channels.
3565 Now the mode changes are saved and notified correctly. The
3566 affected file is /silcd/packet_receive.c.
3568 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3569 They really did not replace the cache entry in the ID Cache.
3570 Now they do that. Affected file silcd/idlist.c.
3572 * Fixed the KICK notify handling in the Irssi SILC client to
3573 update the channel records so that the kicked client does not
3574 appear to be on the channel. The affected file is
3575 irssi/src/silc/core/silc-channels.c.
3577 * Always update the conn->current_channel when executing command
3578 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3580 * Fixed the KILL notify handling in Irssi SILC client to remove
3581 the killed client on all channels.
3583 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3585 * Fixed the silc_parse_command_line to remove extra spaces
3586 from the start and end of the arguments. Affected file is
3587 lib/silcutil/silcutil.c.
3589 * Cancel and free any active protocol in the function
3590 silc_server_close_connection. Affected file silcd/server.c.
3592 * Cancel and free any active protocol in the function
3593 silc_client_close_connction. Affected file is
3594 lib/silcclient/client.c.
3596 * Do not execute the KILL command for clients that are in
3597 history (ie. they are not in the network). Affected file is
3600 * Fixed KILL notify handling, client does not crash anymore.
3601 Affected file irssi/src/silc/core/silc-channels.c.
3603 * Reduced the default packet buffer size from 2048 to 1024 in
3604 lib/silccore/silcpacket.c.
3606 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3607 counter to the SKE context that is incresed when the SKE library
3608 performs async operation outside the library. If the outside
3609 process frees the SKE context and FREED status will be set
3610 and the library will detect after the sync operation that the
3611 libary is freed. The affected files are
3612 lib/silcske/silcske[_status].[ch].
3614 * Resolve the client entry information in the function
3615 silc_client_channel_message to assure that NULL pointer is not
3616 passed as client entry to the application. */
3618 * Fixed the task timeout calculation to assure that there is
3619 never negative timeouts. The affected file is
3620 lib/silcutil/silcschedule.c.
3622 * Fixed the channel user mode notification sending in server.
3623 It was sent point-to-point to the router (or to server by router)
3624 but it needs to be destined to a channel. The routines now
3625 supports sending the channel user mode notifys to the channels
3626 when announcing clients and channels. Affected files are
3627 silcd/server.c and silcd/packet_receive.c.
3629 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3630 It did not actually replace the old channel entry in the cache.
3631 Affected file lib/silcclient/client_notify.c.
3633 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3635 * Fixed a possible crash in silc_packet_send_prepare. It now
3636 assures always that there is enough space in the buffer and
3637 at the tail area of the buffer (for MAC).
3639 Fixed the inbound buffer reallocation in silc_packet_read.
3640 It was old code and did not handle the reallocation correctly.
3643 The affected file is lib/silccore/silcpacket.c.
3645 * Fixed buffer overflow in silc_parse_nickname in the file
3646 lib/silcutil/silcutil.c.
3648 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3650 * make install generates new server keys only if there is not
3653 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3656 Added check that if the NOREPLY is set then we will not send
3657 the away message. This avoids infinite loop of away messages
3658 if both clients are away. The affected file is
3659 lib/silcclient/client_prvmsg.c.
3661 * Fixed client crash if /NICK was given without arguments.
3662 Affected file lib/silcclient/command.c.
3664 * Server does not send the invite list in INVITE command back
3665 to the client if the list was not altered. Added this notion
3666 to the protocol spec as well. Affected file silcd/command.c.
3668 Fixed possible crash in INVITE command by checking the
3669 value of silc_server_get_client_route command.
3671 * Fixed the INVITE notify type handling. The arguments are now
3672 taken in correct order and client does not crash. The affected
3673 file is irssi/src/silc/core/silc-channels.c.
3675 Removed the "Inviting xxx to channel" message from the
3676 client library away and let the application handle it.
3677 Affected file lib/silcclient/command.c. Added that message
3678 to Irssi SILC client's message formats.
3680 * Fixed CMODE command crash in client. It now checks the
3681 amount of arguments correctly and does not crash. The affected
3682 file is lib/silcclient/command.c.
3684 * Do not create new channel automatically in silc_channels_join
3685 but check whether the channel by that name already exists.
3686 Affected file irssi/silc/core/silc-channels.c.
3688 * Do not send the SERVER_SIGNOFF to router if the disconnected
3689 entity was the router. Affected file silcd/server.c.
3691 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3692 SILC client as it was missing from there.
3694 Added the handling of the KICK notify to the Irssi SILC client
3695 as it was missing. Added "you have been kicked" message to
3696 Irssi SILC client's message modules formats.
3698 Added the handing of the KILL notify to the Irssi SILC client
3699 as it was missing. Added the kill message module formats
3702 The affected file is irssi/src/silc/core/silc-channels.c.
3704 * The router did not save the channel mode the server announced.
3705 Affected file silcd/packet_receive.c.
3707 * Fixed a possible crash in INFO command in server. If the
3708 server did not provide the server info it crashed. Affected
3709 file silcd/command.c.
3711 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3713 * Fixed the GETKEY command in the server to check also the
3714 global list. Otherwise the GETKEY would not work correctly
3715 in normal SILC server. Affected file silcd/command.c.
3717 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3719 * Fixed GETKEY crash, it crashed if the command did not succseed.
3721 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3723 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3724 is now real and not just an macro interface to GMP.
3726 Removed the entire GMP from the source tree and imported new
3727 NSS MPI library instead. Reason for removing GMP is that it is
3728 extremely large and compiles extremely slow. The NSS MPI
3729 is only a few files and compiles in less than 10 seconds.
3730 The speed is also about the same as GMP. The MPI is imported
3731 to lib/silcmath/mpi.
3733 If the system has GMP installed we will still use the GMP.
3734 If it is not then the NSS MPI will be compiled.
3736 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3738 * Merged a long nickname (127 characters long) crash bugfix from
3739 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3741 * Merged a freed memory reference bugfix from Irssi CVS tree.
3742 Affected file irssi/src/core/commands.c.
3744 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3746 * Added the server's public key sving and verification to the
3747 server when performing the SKE. This was missing and the
3748 remote server's (or router's) public key was accepted without
3749 checking whether we have it previously or trust it at all.
3750 Affected file silcd/protocol.c.
3752 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3754 * Check in the silc_server_timeout_remote if protocol is active
3755 and make sure that the protocol's final callback is called so
3756 that all memory if freed. Affected file silcd/server.c.
3758 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3760 * silc_server_whois_send_reply crashed the server if the nickname
3761 was 127 characters long. Affected file silcd/command.c.
3763 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3765 * Added sanity check to the silc_server_new_client. If the hostname
3766 is provided inside username then check that the provided hostname
3767 really is the same as the resolved one. If the hostname was not
3768 resolved then check it from the public key. Affected file is
3769 silcd/packet_receive.c.
3771 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3772 if the server disconnected us and the connection is not valid
3773 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3775 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3776 the library to the lib/silcutil/silcutil.[ch].
3778 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Close log file after open. Affected file
3781 lib/silcutil/silclog.c.
3783 * Check whether sock == NULL in silc_client_send_packet and return
3784 if it is. Affected file lib/silcclient/silcclient.c.
3786 * Check rec->entry == NULL in the Irssi SILC Client before
3787 sending the channel message. Affecte file is
3788 irssi/src/silc/core/silc-servers.c.
3790 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Merged a splitted window bugfix from Irssi CVS tree. The
3793 affected file is irssi/src/fe-text/textbuffer-view.c.
3795 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3796 It did not print nickname.
3798 * Improved the distributions system a bit.
3800 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3802 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3803 irssi/src/fe-text/gui-window.c.
3805 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3806 to in-active server. The affected file is
3807 irssi/src/silc/core/client_ops.c.
3809 * Resolve the client in USERS command reply if the entry does
3810 not have username resolved. The affected file is
3811 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3812 command to WHOIS command to really resolve stuff. The USERS
3813 is not used any more in any critical section so WHOIS can
3814 be used even though it might be slower than IDENTIFY.
3816 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3819 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Changed the protocol API a bit more consistent in the
3822 lib/silccore/silcprotocol.[ch].
3824 * Changed the following headers to ROBODoc format:
3826 lib/silccore/silcpayload.h
3827 lib/silccore/silcprotocol.h
3828 lib/silccore/silcsockconn.h
3830 All core library headers are now formatted.
3832 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3834 * Fixed a bug in Irssi SILC client; do not show that you are
3835 server/router operator if you really are not. Affected file is
3836 irssi/src/silc/core/client_ops.c.
3838 * Renamed silc_command_free_payload to silc_command_payload_free.
3839 Affected file lib/silccore/silccommand.h
3841 * Added silcmath.h to include the prototoypes of various routines
3842 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3845 * Changed the following headers to ROBODoc format:
3847 lib/silccore/silcchannel.h
3848 lib/silccore/silccommand.h
3849 lib/silccore/silcid.h
3850 lib/silccore/silcidcache.h
3851 lib/silccore/silcmode.h
3852 lib/silccore/silcnotify.h
3853 lib/silccore/silcpacket.h
3854 lib/silcmath/silcmath.h
3856 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3858 * Added checking to the server code not to start the server if
3859 ciphers and stuff are not configured properly. Affected files
3860 silcd/serverconfig.[h] and silcd/server.c.
3862 * Changed the layout of the header files of the public interfaces
3863 in the SILC libraries. The new layout supports ROBODoc
3864 documentation tool (and some others) so that it is easy to create
3865 a library reference manual. All the other headers and source
3866 code must still follow the CodingStyle document. Also source
3867 code must not include these ROBODoc stuffs, only the headers.
3868 Furthermore, all public interface headers must now be named
3869 by using `silc' prefix, example: silcapi.h, silccipher.h.
3870 Some files were renamed due to this. All the other headers
3871 must not be used as public interfaces. I will update the
3872 CodingStyle document later. Changed following headers, so far:
3874 lib/silcclient/silcapi.h
3875 lib/silccore/silcauth.h
3876 lib/silccore/silcprivate.h
3877 lib/silccrypt/silcdh.h
3879 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3883 * Removed silc_client_packet_send_flush from the client library
3884 as it is not needed. Affected file lib/silcclient/client.[ch].
3886 * Added printing of message of unresolved authentication method
3887 to the Irssi SILC client. Added it to the module formats.
3888 Removed the same message from the client library.
3890 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3892 * Added new distribution feature, DISTLABEL. Every distribution
3893 can define own preprocessor label that can be used in the
3894 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3895 file distributions, acconfig.h.pre and prepare.
3897 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Added Makefile.defines_int to include the actual definitions
3900 for Makefile.defines.in. Tested the new distribution system,
3901 created distributions and tested installation.
3903 * Added AWAY message printing to the Irssi SILC client. Added
3904 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3906 * Added SCONNECT command to call the SILC's CONNECT command.
3907 Cannot use CONNECT directly since Irssi uses that internally.
3908 Affected file irssi/src/silc/core/silc-servers.c.
3910 Added ACTION local command. It is same as ME command but takes
3911 the channel as mandatory argument.
3913 Rewrote some of the Irssi's help files to suite for SILC
3916 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Added Makefile.defines[.in] that should for now on be included
3919 in all Makefile.am file in the source tree. That file includes
3920 all common compilation definitions for SILC source tree.
3922 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3924 * Minor changes to the ./prepare script to change the package
3925 name according the distribution name to the configure.in.
3927 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3929 * Created new distribution system. Added file `distributions'
3930 that defines all the distributions that can be created out of
3931 the SILC source tree. The ./prepare script now reads that
3932 file to determine how to prepare the distributions. The
3933 first argument to the ./prepare is the name of the distribution
3934 and second is the version of the distribution. If given
3935 without arguments it creates the default (toolkit) distribution
3936 with the default version (defined in ./prepare).
3938 All Makefile.am files that are subject to the distributions
3939 are now named as Makefile.am.pre. These are ./Makefile.am
3940 and lib/Makefile.am. Others may be changed later.
3942 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3944 * Added invite list, ban list, some key management and connection
3945 error message printing to module formats in the Irssi SILC client.
3947 * Added new silc_client_set_away_message to set the away message
3948 that is back to the person who sent private message. The
3949 affected file lib/silcclient/silcapi.h and the
3950 lib/silcclient/client_prvmsg.c.
3952 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3954 * Fixed the private message sending in the Irssi SILC client,
3955 added local command KEY to the Irssi SILC client.
3957 Added key management and key agreement message formats to the
3958 irssi/src/fe-common/silc/module-formats.[ch].
3960 Added USERS (alias WHO) printing, server/router operator
3961 indication and LIST command printing to the module formats.
3963 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3965 * Fixed channel joining notify handling, cumode notify handling
3966 from Irssi SILC client.
3968 * Added SILC specific module-formats to the Irssi SILC client so
3969 that SILC specific message hilighting, colors etc is possible.
3970 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3972 Added channel mode, channel user mode, actions, notices,
3973 whois and whowas printing to the the module-formats.c.
3975 * Fixed a bug in channel deletion in the server. The channel
3976 is not left to the cache even if the channel founder auth mode
3977 is set when there are no users anymore on the channel. Affected
3978 file silcd/server.c.
3980 * The silc_net_localhost now resolves the entire hostname including
3981 the domain name. Affected file lib/silcutil/silcnet.c.
3983 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Changed the ask_passphrase client operation to be ascynchronous.
3986 It has now a completion callback and a context that the
3987 application must call after it has got the passphrase from
3988 the user. Affected files lib/silcclient/silcapi.h,
3989 lib/silcclient/protocol.c, lib/silcclient/command.c and
3992 Added SilcAskPassphrase callback that the application calls
3993 to deliver the passphrase to the library.
3995 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3996 The public key verification and especially a certificate
3997 verification is asynchronous procedure.
3999 Added new SILC_SKE_STATUS_PENDING status to indicate the
4000 request is pending and a callback will be called to finalize
4003 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4004 indicate that remote end did not send its public key (or
4005 certificate), even though we require it. Added check for this
4006 condition in the SKE. This was a security bug, now fixed.
4008 Defined new SilcSKEVerifyCbCompletion callback that is called
4009 when the verification process is completed.
4011 The affected files lib/silcske/silcske_status.h and
4012 lib/silcske/silcske.[ch].
4014 * Changed the verify_public_key client operation to be async
4015 as well. Defined SilcVerifyPublicKey callback that is used to
4016 indicate the success of the public key verification process.
4018 Changed the server and client to use the new async client
4021 * Changed the Irssi SILC client's internal scheduler to be called
4022 twice as many times as it used to be. As a result the client
4023 should be a bit faster now. Affected file is
4024 irssi/src/silc/core/silc-core.c.
4026 * Added support to Irssi SILC client of asynchronous public key
4027 verification and passphrase inquiry. Affected file is
4028 irssi/src/silc/core/silc-core.c.
4030 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Do not say "You have left channel %s" in client library.
4033 Moved it to the application. Affected files are
4034 lib/silcclient/command.c and silc/client_ops.c.
4036 * Fixed silc_client_get_clients. Command context was not
4037 duplicated and was freed memory in the callback. Affected
4038 file lib/silcclient/idlist.c.
4040 * Do not say "you are now talking..." on JOIN command in the
4041 client library. The appliation must handle it.
4043 * Do not say ".. changed topic to" in command reply in the
4044 client libary. The application must handle it.
4046 * Fixed TOPIC command sending in the client library.
4048 * Fixed a memory leak in silc_client_command_free in the file
4049 lib/silcclient/command.c.
4051 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4053 * Imported a modified version of Irssi client to the source tree.
4054 The Irssi will be used to create a new client called
4055 Irssi SILC. Imported to irssi/.
4057 Added silc_core_init_finish function to the Irssi. Affected
4058 file irssi/configure.in.
4060 A lot changes in the Makefile.ams around the irssi tree.
4062 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4064 * Do not rehash if the new size is same as the old size of the
4065 hash table, in the silc_hash_table_rehash*. The affected file
4066 lib/silcutil/silchashtable.c.
4068 * Replaced hash_table_del_by_context calls from the server
4069 (when channel->user_list and client->channels) to the
4070 hash_table_del as it is sufficient and faster.
4072 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4074 * Added silc_hash_table_list, silc_hash_table_get and the
4075 SilcHashTableList structure to provide an alternative way to
4076 traverse the hash table. The affected files are
4077 lib/silcutil/silchashtable.[ch].
4079 * Changed the server's idlist routines to use the hash table
4080 routines to optimize the code.
4082 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Replaced the client entry's `channel' list and channel entry's
4085 `user_list' list to hash tables for optimized lookup. Changed
4086 the code to use the hash table interface around the code.
4087 Affected file lib/silcd/idlist.[ch].
4089 * Added `auto_rehash' boolean argument to the function
4090 silc_hash_table_alloc to indicate whether the hash table should
4091 auto-rehash when it thinks is appropriate time. It will
4092 increase the hash table size if the there is twice as much
4093 entries in the table than the size of the table, and will
4094 decrease the size if there are twice as less entries than
4095 the size of the table.
4097 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4099 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4101 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * silc_idcache_purge_by_context deletes the entry now by context
4104 as it is supposed to do. Affected file lib/silccore/idcache.c.
4106 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4107 client is not anymore valid (WHOWAS givens the info) and not
4108 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4110 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4112 * Removed the `data' and `data_len' arguments from the ID Cache
4113 interfaces and added `name' argument. ID Cache does not handle
4114 anymore the binary data only a names associated with given ID.
4116 * When hashing a Client ID with silc_hash_id the entire ID is
4117 not hashed anymore, instead only the hash of the Client ID is
4118 hashed. This way we can access the Client ID from the cache
4119 with Client ID but with the hash of the ID (which is a hash of
4120 the nickname) as well without any difference in performance.
4122 Added also silc_idcache_find_by_id_one_ext to do one on one
4123 searching when we have the actual ID. Added also function
4124 silc_hash_client_id_compare. The affected files are
4125 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4127 * When hashing the name associated with a ID it is always done
4128 in lowercase. This way we can access the cache without worrying
4129 about case-sensitivity, even though, for example nicknames are
4132 * Fixed a bug in server with channel message sending. It put
4133 wrong ID type as destination ID. The affected file
4134 silcd/packet_send.c.
4136 * silc_idcache_del_by_context now deletes from all hash tables
4137 by context. Affected file lib/silccore/idcache.c.
4139 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4141 * Changed the client library to use the new ID Cache interface.
4142 Changes around the source tree.
4144 * Added silc_hash_table_rehash_ext to rehash with specific
4145 hash function. Affected file lib/silcutil/silchashtable.[ch].
4147 * Added silc_hash_string_compare to compare two strings in the
4148 hash table. Affected file lib/silcutil/silcutil.[ch].
4150 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4152 * Added new function silc_idcache_del_by_context into the
4153 lib/silccore/idcache.[ch].
4155 * Changed the server's ID list routines to use the new ID Cache
4156 interface. Changes around the source tree.
4158 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4160 * Added silc_hash_table_del[_by_context]_ext functions in to the
4161 lib/silcutil/silchashtable.[ch].
4163 Removed silc_hash_table_find_all* routines and added new
4164 silc_hash_table_find_foreach to replace them.
4166 Added silc_hash_table_replace_ext function as extended
4167 replacing function. Separated the simple hash table interface
4168 from the extended hash table interface in the file
4169 lib/silcutil/silchashtable.h.
4171 * Fixed minor bugs and changed it to use some of the new
4172 hash table functions in lib/silccore/idcache.c
4174 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4176 * Added new function silc_hash_table_find_all to return all keys
4177 in the hash table by the specified key. As the hash table is
4178 collision resistant it also makes it possible to have several
4179 duplicate keys in the hash table. This function may be used to
4180 find all of the keys from the hash.
4182 Added user_context arguments to the SilcHashFunction,
4183 SilcHashCompare and SilcHashDestructor to deliver user specified
4186 Added new fuctions silc_hash_table_find[_all]_ext to do
4187 extended lookup with specified hash and compare functions and
4188 specified user contexts.
4190 Added new function silc_hash_table_add_ext to add the key
4191 with specified hash function and user context.
4193 Added new function silc_hash_table_foreach to traverse all
4194 entrys in the hash table. Added SilcHashForeach callback
4197 Added new function silc_hash_table_del_by_context to delete
4198 the entry only if the context associated with the key matches.
4200 Affected files are lib/silcutil/silchashtable.[ch].
4202 * Removed silc_hash_[server/client/channel]_id and added just
4203 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4204 silc_hash_id_compare to compare two ID's using as the hash table
4205 comparison function. Added also silc_hash_data to hash
4206 binary data and silc_hash_data_compare to compare it.
4208 * Removed silc_idlist_find_client_by_hash as it is not needed
4209 anymore. Affected file silcd/idlist.[ch].
4211 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4212 to use internally the SilcHashTable. The new ID Cache is a lot
4213 faster than the old one. Some of the ID Cache interface was also
4214 rewritten and obsolete and stupid functions were removed.
4216 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4218 * Added entry_count field to the SilcHashTable to keep the number
4219 of the entries in the table. Implemented the function
4220 silc_hash_table_rehash. Added new function
4221 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4223 Fixed a minor bug in silc_hash_table_free.
4225 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4226 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4227 into the lib/silcutil/silcutil.[ch].
4229 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Implemented a collision resistant hash table into the
4232 lib/silcutil/silchashtable[ch]. See the header and the source
4233 for the SilcHashTable API.
4235 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4237 * Merged dotconf version 1.0.2 into lib/dotconf.
4239 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4241 * Do not compile anything in lib/silcsim/* if the SIM support
4242 is not enabled. The tree should now compile without problems
4245 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Compiled the SILC under cygwin. Compiled and tested briefly
4248 without problems. More tests needed. The SIMs didn't compile
4251 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4253 * Fixed possible crash in silc_get_username in the
4254 lib/silcutil/silcutil.c.
4256 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Fixed a va_arg in silc/client_ops.c.
4260 * Oops, RC5 routines were named AES and caused some problems
4261 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4263 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * Added new SilcIDIP structure into the lib/silccore/id.h and
4266 replaced the old `ip' fields from all SILC ID's to that type.
4267 This is a step towards IPv6 support.
4269 The silc_id_get_len takes now the ID as an extra argument.
4270 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4271 both IPv4 and IPv6 based ID's.
4273 The affected files are lib/silccore/id.[ch] and other files
4274 around the tree using these routines.
4276 * Removed the ID length arguments in server from various
4277 silc_server_send_notify_* routines -> they are not needed
4280 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4282 * Fixed memory leak in silc_encode_pem_file in the file
4283 lib/silcutil/silcutil.c.
4285 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Check minor version as well in the SKE. Affected files are
4288 silcd/protocol.c and lib/silcclient/protocol.c.
4290 * Added --identifier option to the server so that an identifier
4291 can be when creating the public key for the server. Affected
4292 file is silcd/silcd.c.
4294 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4295 lib/silccrypt/silcpkcs.c.
4297 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4299 * Register default ciphers and stuff when using -C option with
4300 the server. Affected file sildc/silcd.c.
4302 * Put back the servers public key filename format, it is better
4303 than the new one. For now, the client keys are saved with the
4304 new filename format. The affected file silc/client_ops.c.
4306 * Implemented the Cipher API for the rest of the ciphers that
4307 did not implement it or implemented it the wrong way.
4309 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Register default ciphers and stuff when using the -S option
4312 in the client. Affected file silc/silc.c. Same also when
4313 creating new key pair with -C option.
4315 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Fixed the silc_verify_public_key client operation function to
4318 save the public keys differently. The fingerprint is now
4319 used as filename and not the hostname. This way also the
4320 client keys are saved uniquely and not with hostnames. The
4321 affected file is silc/client_ops.c.
4323 * Trimmed the silc_hash_fingerprint function to remove extra
4324 whitespaces from the end of the fingerprint. The affected
4325 file is lib/silccrypt/silchash.c.
4329 * Added silc_cipher_register_default function to register all
4330 default ciphers. It can be used when configuration files
4331 does not exist and the application does not want any specific
4332 ciphers in any specific order.
4334 The SilcDList is now used as silc_cipher_list dynamically
4335 allocated cipher list. Removed the static list all together
4336 and now all ciphers must be allocated to the dynamic list.
4337 The silc_cipher_alloc routine was changed to check only the
4340 All silc_cipher_* routines that used to return int returns
4343 The affected files lib/silccrypt/silccrypt.[ch].
4345 * The same thing was done to silc_hash_* as for silc_cipher_*
4346 routines. Affected files lib/silccrypt/silchash.[ch].
4348 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4349 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4350 Added also silc_pkcs_[un]register[_default] functions.
4351 Removed the data_context from the PKCS API.
4353 * Added silc_hmac_register_default function to register default
4354 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4355 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4356 to unregister all hmacs at once.
4358 * Register the default ciphers, hash functions, PKCSs and HMACs
4359 if client's configuration file does not exist. The affected
4362 * The client did not load the hash functions from the SIM
4363 modules at all. Added support for this. Affected file is
4364 silc/clientconfig.c.
4366 * When decoding public key with silc_pkcs_public_key_decode, check
4367 the supported algorithm only if PKCS are registered. Affected
4368 file lib/silccrypt/silcpkcs.c. The same was done with the
4369 silc_pkcs_private_key_decode.
4371 * Fixed the SILC List routines to keep the list always in order.
4372 It used to change the list's order when traversing the list but
4373 not it preserves the order. Affected file lib/trq/silclist.h.
4375 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4377 * Added the client library to use the SilcSocketConnection's
4378 reference counter (by silc_socket_dup) to prevent the bug that
4379 the socket object may be freed underneath async operation.
4381 * The name resolv library checking fixes in the configure.in.pre.
4384 * Created new version of the protocol drafts for future
4385 development. The -03 drafts are the ones that will be changed
4386 in the trunk now and the -02 will remain as they are.
4388 * Send list of CUMODE notifys to the router when announcing
4389 the channel users to the router. Affected file silcd/server.c.
4390 If the router receiving channel founder CUMODE for a channel
4391 that already has channel founder it will send CUMODE notify
4392 to the sender to remove the channel founder rights from the
4393 announced client. Affected file silcd/packet_receive.c.
4395 * The CUMODE notify may now use Server ID as well as the entity
4396 who changes the mode. Updated protocool specs.
4398 * Updated INSTALL and README files.
4400 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4402 * New web pages in the http://silc.pspt.fi. The pages was
4407 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4409 * Implemented the [DenyConnectin] config section in the server.
4410 Added silc_server_config_denied_conn to check whether incoming
4411 connection is denied. Affected file silcd/serverconfig.[ch].
4413 * Do not check the ports when checking the incoming configuration
4414 data if the port is 0, meaning any. Affected file is
4415 silcd/serverconfig.c.
4417 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4419 * Fixed buffer overflow in silc_string_compare in the file
4420 lib/silcutil/silcutil.c.
4422 * Fixed double free in silc_server_command_leave in the file
4425 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Fixed the version checking in the server. Affected file is
4430 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4432 * Fixed the configuration data fetching when accepting new
4433 connections in the server. Affected file silcd/server.c.
4435 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4437 * Added `sender_entry' argument to the function
4438 silc_server_packet_relay_to_channel so that we can check
4439 whether some destination actually belongs to the same route
4440 the sender belongs (ie, we must not resend the packet to the
4441 sender). Affected file silcd/packet_send.[ch].
4443 * Added `servername' field to the SilcClientEntry in the server
4444 to hold the name of the server where client is from. Affected
4445 file is silcd/idlist.h.
4447 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4449 * Moved the channel message encrypting in the router betwen
4450 router connections from silc_server_channel_message to the
4451 silc_server_packet_relay_to_channel since we want to check
4452 whether we have anybody channel before encrypting anything.
4453 Affected files silcd/packet_[receive/send].c.
4455 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4457 * Fixed the [AdminConnection] server config section to support
4458 multiple entries. Affected file silcd/serverconfig.c.
4460 * Added support into the server to check the validity of the
4461 incoming connection before executing any KE or authentication
4464 * The connection configuration is now saved to the KE and
4465 connection auth protocol contexts and not fetched anymore in
4466 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4468 * The local hosts listenning address and port is also resolved
4469 now when starting the server. We want to have the socket object
4470 to include the real address and port for the listener. Added
4471 new function silc_net_check_local_by_sock into the files
4472 lib/silcutil/silcnet.[ch].
4474 * Fixed a broadcast bug in server -> do not broadcast if we
4477 * Fixed a routing bug. Do not route broadcast packets ever.
4478 Broadcast packets must be processed always and not routed since
4479 they may be destined to some other host than yourself and thus
4480 would get routed without no good reason. Affected file is
4483 * Added function silc_server_config_is_primary_route to check
4484 whether primary router connection has been configured (a router
4485 configuration that we are initiating). If there is not, we
4486 will assume that there is only two routers in the SILC network
4487 and we will use the incoming router connection as our primary
4488 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4490 * Changed the order of the broadcasting. Broadcast _after_ the
4491 packet has been processed not before. Affected file is
4494 * Fixed a [ClientConnection] parsing bug. The port was never
4495 parsed correctly thus resulting to port 0. Affected file
4496 silcd/serverconfig.c.
4498 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4499 argument and did not set the broadcast packet flag. Affected
4500 file silcd/packet_send.c. Fixed same bug in the function
4501 silc_server_send_notify as well.
4503 * If we receive NEW_ID packet for our own ID in the server, ignore
4506 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4510 * Removed the nickname from the Private Message Payload.
4511 Updated the code and the protocol specs.
4513 * Updated protocol specs for submitting to the IETF.
4515 * Tweaked the Random Number Generator a bit. Affected file
4516 lib/silccrypt/silcrng.c. Exported a new function
4517 silc_rng_[global]_add_noise which can be used to add more
4520 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Do not parse packets with different timeout when protocol
4523 is active -> may cause problem with rekey. Affected file
4526 * When server receives signoff notify it must not create
4527 new channel key if the client is on any channels since the
4528 sender of the signoff notify will create it.
4530 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Added printing of error messages during SKE protocol from the
4533 failure packet sent by server during SKE. Affected file
4536 * Removed the client's failure_callback handling with timeout
4537 and handle it immediately when received.
4539 * The SKE library returned wrong type in SUCCESS and FAILURE
4540 packets. They must be 32 bit MSB not 16 bit MSB.
4542 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4544 * Ok, rewrote the logic of the re-key and now it seems to work.
4545 I tested it on high traffic with frequent re-keys without
4546 problems. Added hmac_receive (and renamed hmac to hmac_send)
4547 in SilcClientConnection in lib/silcclient/client.h and
4548 in SilcIDListData in silcd/idlist.h. Also, removed the
4549 SilcPacketParserContext's cipher and hmac fields as they are
4550 not needed anymore and actually caused some problems when
4551 the ciphers and hmac's changed underneath the packet parser.
4553 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4555 * If re-key protocol is active then process the incoming packets
4556 synchronously since we must assure that icoming packets encrypted
4557 with the old key is processed before the new keys is set to
4558 use. This is true other packets than for REKEY packets.
4559 Affected file silcd/server.c. The same was done to client library
4560 as well, affected file lib/silcclient/client.c.
4562 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * Fixed bug in client and server to accept the force send if
4565 the packet is send from silc_[server/client]_packet_process
4566 function. Otherwise the packets are never delivered, oops.
4568 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Disable force sending of packets when REKEY protocol is active.
4571 We must assure that no packet is sent directly when rekey is
4572 performed. All packets must be sent through packet queue.
4573 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4574 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4575 function is silc_[server/client]_packet_send_real to check
4578 * Replaced the SIM paths from example config files to
4579 /usr/local/modules. Also, make install creates now
4580 /usr/local/silc/logs directory to hold all the SILC server
4583 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4585 * Made the configure.in.pre work on Solaris. Patch by salo.
4587 * Made all ciphers compatible with non-x86 machines. Defined
4588 CBC mode macros into lib/silccrypt/ciphers_def.h.
4590 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4592 * Fixed the make install.
4594 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4596 * When MAC computation fails the silc_packet_decrypt returned 0
4597 even though it was supposed to return -1. Fixed this. The
4598 affected file is lib/silccore/silcpacket.c.
4600 * Do not replace the config files in /etc/silc (in make install)
4601 if they already exist. Affected file ./Makefile.am.
4603 * Do not send re-key packets immediately but through packet queue.
4604 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4606 * Changed silc_net_check_host_by_sock to return FALSE if the
4607 IP/DNS could not be resolved. Though, it returns the IP address
4608 now even if it could not resolve it (but returns also FALSE).
4609 Affected file lib/silcutil/silcnet.[ch].
4611 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4613 * Added silc_pkcs_decode_identifier to decode the public key's
4614 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4615 Added also silc_pkcs_free_identifier. Added also new context
4616 SilcPublicKeyIdentifier.
4618 * Added -S option to the silc client. It is used to dump the
4619 contents of the specified public key file.
4621 * Changed the PKCS api to return the public key length when
4622 setting the public key.
4624 * Fixed a fatal bug in the public and private key file loading.
4625 Affected file lib/silccrypt/silcpkcs.c.
4627 * Execute the packet parsing for client with zero (0) timeout
4628 if the protocol is active. Affected file silcd/server.c.
4630 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4632 * Made the key generation options to the silcd program. Added
4633 -C option, equivalent to client's option.
4635 * Added new [ServerKeys] config section to the server. It
4636 configures the server's public and private key.
4638 * Defined generic Public Key Payload into the protocol
4639 specification to send specific type of public keys and
4642 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4643 public key or certificate.
4645 * Implemented the GETKEY command to the server and to the
4646 client library and on user interface.
4648 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4650 * Made preliminary `make install' work.

4679 SilcClientConnection structure; not needed. Affected file is
4680 lib/silcclient/client.h.
4684 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4686 * Do not ask whether user wants to use the negotiated private key
4687 for private messages, just use it. Affected file is
4688 silc/local_command.c.
4690 * Added `send_enc_key' and `enc_key_len' fields to the
4691 SilcIDListData structure since they are needed in the re-key
4692 phase. Affected file is silcd/idlist.[ch].
4694 * Implemented the simple re-key protocol into the server.

4706 the PFS is to be performed in the re-key. Affected file is
4709 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4711 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4712 int64 of at least the xintXX size. If void * is less that 4
4713 bytes uint32 * will be used. Defined bool as boolean.
4715 * Changed _ALL_ unsigned long and unsigned int to uint32,
4716 unsgined short to uint16 in the source tree.
4718 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4719 not handle clients that has entry->data.registered == FALSE.
4720 They are not in the network anymore. Affected file is
4723 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4725 * Implemented the sending of the SERVER_SIGNOFF notify in the
4726 server. Affected file is silcd/server.c.
4728 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4729 Added also silc_notify_payload_encode_args into the

4732 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4733 Affected file silcd/packet_receive.c.
4735 * Implemented the SERVER_SIGNOFF notify handling in the client
4736 library. Affected file lib/silcclient/client_notify.c. Also,
4737 implemnted the printing of the SERVER_SIGNOFF info to the
4738 application. Affected file silc/client_ops.c.
4740 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4741 if the deleting was successful. Affected file silcd/idlist.[ch].
4743 * Added support for public key authentication in the connection
4744 authentication protocol in the client library. Affected file
4745 lib/silcclient/protocol.c.
4747 * Changed the server's silc_idlist_get_clients_by_* interface
4748 to support already allocated array so that new entries may be
4749 added to pre-allocated array. Affected file silcd/idlist.[ch].
4750 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4751 and command replies.
4753 * All command reply functions in the server now calls the
4754 pending command callback even if error occured. This way the
4755 error will be delivered to the client as well. Affected files
4756 silcd/command.c and silcd/command_reply.c.
4758 * Fixed INFO command to return local server's info if no server
4759 was provided. Affected file lib/silcclient/command.c.
4761 * Removed RESTART command for good. Updated the code and the
4764 * Rewrote parts of the task system. It is a bit simpler now.
4765 Removed unsued task priorities. The affected files are
4766 lib/silcutil/silctask.[ch].
4768 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4770 * Moved the USERS printing from the library to the application.
4771 Affected files lib/silcclient/command.c and silc/client_ops.c.
4773 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4777 * Added channel key re-key support. The re-key is perfomed
4778 only by the router and is done once in an hour. Added `rekey'
4779 field to the SilcChannelEntry in the server. Affected files
4780 silcd/server.c and silcd/idlist.h.
4782 * Added silc_task_unregister_by_context into the file
4783 lib/silcutil/silctask.[ch].
4785 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4787 * Added SILC_UMODE_GONE mode to indicate when the client is not
4788 present in the SILC network. Added also support to the local
4789 command AWAY that will set this mode. Added support of showing
4790 "xxx is gone" in WHOIS command. The USERS command shows the
4791 gone status as well.
4793 * Fixed setting server and router operator privileges in the
4794 server's UMODE command. Affected file silcd/command.c.
4796 * Merged the SKE KE1 and KE2 payloads into one payload. The
4797 new KE payload is equivalent to the old KE2 payload.
4799 Cleaned up the SKE Start Payload parsing. It now uses the
4800 simple buffer unformatting to do the parsing. A lot faster
4803 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4804 to the SKE that is used to indicate whether both of the SKE
4805 parties should perform authentication. By default only the
4806 responder performs authentication. By setting this flag also
4807 the initiator must do authentication. By default it is unset
4808 since in normal SKE case, client to server connection, only
4809 the responder should do authentication. When doing SKE between
4810 two clients both should perform authentication. Updated the
4811 code and the protocol specs.
4813 * A little fix to IDENTIFY command in the server. Search the
4814 client first by hash not nickname. Affected file is
4817 * Fixed the silc_client_close_connection to support closing
4818 the client to client connections wihtout deleting too much
4819 data. Affected file lib/silcclient/client.c.
4821 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4822 are received if protocol used to be active but is not anymore
4823 the application would crash due to NULL pointer dereference.
4824 Affected files silcd/server.c and lib/silcclient/client.c.
4826 * Added `hash' field to the SilcClientConnection to include
4827 the hash function negotiated in the SKE protocol.
4829 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4830 to set the channel founder authentication data. A client can
4831 claim the founder rights later by providing the authentication
4832 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4833 This way the channel founder can regain the channel founder
4834 privileges even it is left the channel. This works only on
4835 local server and the client must be connected to the same
4836 server to be able to regain the founder rights. Updated the
4837 protocol specs accordingly.
4839 Added support to the CMODE command in the client to set the
4840 founder auth data. Read the README to see how to set it.
4842 Added support to the CUMODE command to claim the founder
4843 rights. Read the README to see how to do it.
4845 Added support for the founder authentication to the Channel
4846 Entry in the server. Affected file silcd/idlist.h.
4848 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4849 server's CMODE command. Affected file silcd/command.c.
4851 * Added the following new functions into lib/silccore/silcauth.[ch]:
4852 silc_auth_get_method and silc_auth_get_data.
4854 * The server now saves the remote hosts public key to the
4855 SilcIDListData pointer. Affected file silcd/protocol.c.
4857 * The normal server now does not remove the channel entry from
4858 the cache if the founder authentication data is set. It used
4859 to remove it if the founder was the last one on the channel on
4860 the server and left the channel. The auth data is saved and
4861 if the channel is re-joined later the old entry is used with
4862 the old auth data. Affected files silcd/command_reply.c and
4865 * Removed the `pkcs' field from the SilcIDListData structure
4866 in the server; it is not used. Affected file silcd/idlist.h.
4868 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4870 * Fixed packet processing on slow links. Partial packets were
4871 never re-processed because the incoming data buffer was cleared
4872 by the application. Application must not directly clear the
4873 sock->inbuf, the packet processing routines handle it. Fixed
4874 this in client library and in server.
4876 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4878 * Fixed the WHOIS and IDENTIFY send reply function to really
4879 check whether to send list or just one entry. Affected file
4882 * Cleaned up the LEAVE command's channel key distribution. The
4883 affected file silcd/command.c.
4885 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4886 can enforce the channel mode as well. In that case the ID
4887 includes the ID of the server. The code now enforces the
4888 mode change if the router have different mode than the server.
4890 * The notify client operation with CMODE_CHANGE notify can now
4891 return NULL client_entry pointer if the CMODE was not changed
4892 by client. Application must check for this.
4894 * Added <Server ID> argument to INFO command to support server
4895 info fetching by Server ID.
4897 * Added silc_server_announce_get_channel_users to get assembled
4898 packets of channel users of the specified channel. Affected
4899 file silcd/server.[ch].
4901 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4902 was freed underneath the ID Cache.
4904 * Re-announce clients when the server received CHANNEL_CHANGE
4905 notify from the router. Affected file silcd/packet_send.c.
4907 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4909 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4910 crashed since it did not handle the fact that there is no cipher
4911 called "3" and didn't check the error condition. Now fixed.
4913 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4914 flag. It can be used to send message requests.
4916 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4918 * Implemented the RESTART command in the client.
4920 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4921 notice type messages. Added notice printing to the user
4924 * The channel keys are not re-generated if the channel's mode
4925 is PRIVKEY, ie private key on the channel exists. Affected
4926 files silcd/server.c and silcd/command.c.
4928 * Fixed a little bug in channel message delivery when channel
4929 private keys are set in the server. Affected file is
4930 silcd/packet_send.c.
4932 * Changed the setting on channel->on_channel = TRUE from the
4933 silc_client_save_channel_key to the JOIN command reply. The
4934 key payload is not received if the private channel key is set.
4935 Affected file lib/silcclient/command_reply.c and the
4936 lib/silcclient/client_channel.c.
4938 * When the CMODE_CHANGE notify is sent and the channel private
4939 key mode is removed the channel key must be re-generated in
4940 other cells as well. Added this support for the router in the
4941 silcd/packet_receive.c.
4943 * Added new local command NOTICE to send notice message on
4944 channel. Affected file silc/local_command.[ch].
4946 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Added new local command ME to the client. It is used to send
4949 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4950 some action. Affected file silc/local_command.[ch].
4952 * Changed channel_message and private_message client operations
4953 to deliver the message flags to the application. Added also
4954 the `flags' arguments to the silc_client_send_channel_message
4955 and silc_client_send_private_message functions. Affected file
4958 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4960 * Redefined the Private Message Payload to support private message
4961 keys and to support the new private message flags. Updated
4962 the protocol specs. Flags makes it possible to have for example
4963 CTCP style messages.
4965 * Added new type SilcPrivateMessagePayload and defined an API
4966 for it in the lib/silcclient/silcprivate.[ch].
4968 * Tested private message private keys successfully. Tested the
4969 private message key set, unset and list commands with the new
4972 * Redefined the Channel Message Payload to include the channel
4973 message flags (equal with private message flags) to support
4974 for example CTCP style messages.
4976 * Defined some of the message (for channel and private message)
4977 flags. Updated the protocol specs and added the flags to the
4978 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4980 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4982 * Added SilcKeyAgreementStatus type to the key agreement routines
4983 to indicate the current status and error if one occured.
4984 The status types are defined in the lib/silcclient/silcapi.h.
4986 * Added new local command KEY that is used to set and unset private
4987 keys for channels, set and unset private keys for private messages
4988 with remote clients and to send key agreement requests and
4989 negotiate the key agreement protocol with remote client. The
4990 key agreement is supported only to negotiate private message keys,
4991 it currently cannot be used to negotiate private keys for channels,
4992 as it is not convenient for that purpose.
4994 * Fixed a minor pending callback setting bug in the function
4995 silc_client_get_client_by_id_resolve, now the function works.
4996 Affected file lib/silcclient/idlist.c.
4998 * Added function silc_net_get_local_port to get local bound
4999 port by socket. Added to lib/silcutil/silcnet.[ch].
5001 * Added `sockets' and `sockets_count' fields to the SilcClient
5002 object. They hold the sockets of the listenning sockets in
5003 the client. Listenning sockets may be for example the key
5004 agreement server. Affected file lib/silcclient/client.[ch].
5005 Added functions the silc_client_add_socket and the
5006 silc_client_del_socket. They are exported to the application
5009 * Added ~./silc/clientkeys to support other client's public keys.
5011 * Renamed verify_server_key client operation to verify_public_key
5012 and added one argument to indicate the type of the connection
5013 (server, client etc.).
5015 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5017 * Added silc_server_connection_auth_request to handle the
5018 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5019 silcd/packet_receive.[ch].
5021 * Added silc_server_send_connection_auth_request into the
5022 silcd/packet_send.c to send the connection auth request packet.
5024 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5027 * Fixed the public key authentication in responder side in the
5028 server. The `auth_data' pointer includes the SilcPublicKey
5029 not the path to the public key. Affected file silcd/protocol.c.
5031 * Implemented the public key authentication in the initiator side
5032 in the server. Affected file silcd/protocol.c.
5034 * Removed the [RedirectClient] config section from the server
5035 configuration. Is not needed and I don't want to implement it.
5037 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * Cleaned up the CMODE command in the server. It now works
5040 correctly and supports all the modes defined in the protocol.
5041 Affected file is silcd/command.c.
5043 * Added `hmac_name' field to the SilcChannelEntry in the server
5044 to hold the default HMAC of the channel. It can be set when
5045 creating the channel (with JOIN command). Affected files
5048 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5049 type to indicate the change of the current cipher and hmac
5050 on the channel. Client can safely ignore the <cipher> argument
5051 (if it chooses to do so) since the CHANNEL_KEY packet will
5052 force the channel key change anyway. The <hmac> argument is
5053 important since the client is responsible of setting the new
5054 HMAC and the hmac key into use.
5056 * Fixed the CMODE command in the client library as well.
5058 * Tested CMODE command in router environment successfully.
5060 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5062 * Show the version of the remote client (or server) when connecting
5063 to the server. It is logged to the log file. Affected file
5064 is silcd/protocol.c.
5066 * Fixed the KILLED notify handling in the client library. The
5067 client must be removed from all channels when receiving the
5070 Also, do not remove the client entry when giving the KILL
5071 command but when the KILLED notify is received.
5073 * Removed silc_idlist_find_client_by_nickname from the server.
5074 Not needed anymore. Affected files silcd/idlist.[ch].
5076 * Implemented the CHANNEL_CHANGE notify type handling to the
5077 server. Affected file silcd/server.c.
5081 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5083 * Added silc_server_send_notify_invite to send the INVITE
5084 notify between routers.
5086 * Implemented the INVITE command correctly to the server.
5088 * Implemented the INVITE notify type handling in the server.
5090 * Implemented the INVITE command to the client library and on the

5095 * Added function silc_server_get_client_resolve to find the
5096 client entry by ID from all ID lists and then resolve it
5097 (using WHOIS) if it cannot be found. Affected file is
5100 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Implemented the BAN command to the client library.
5104 * The JOIN command in the server now checks the invite list
5107 * Changed the silc_command_reply_payload_encode_va and the
5108 silc_command_payload_encode_va to support that if argument is
5109 NULL it ignores and checks the next argument. Affected file
5110 lib/silccore/silccommand.c.
5112 * Added silc_server_send_notify_ban to send the BAN notify
5113 type between routers.
5115 * Chaned the silc_notify_payload_encode to support that if
5116 argument is NULL it ignores and checks the next argument.
5117 Affected file lib/silccore/silcnotify.c.
5119 * Tested ban lists in router environment successfully.
5121 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5123 * Implemented BAN command to the server, in silcd/command.[ch].
5125 * Removed the BAN and INVITE_LIST modes from the CMODE command
5128 * Added function silc_string_match to regex match two strings.
5129 Affected files lib/silcutil/silcutil.[ch].
5131 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5133 * Redefined parts of the SilcChannelEntry in the server to support
5134 the new ban and invite lists.
5136 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5138 * Redefined the INVITE command. The same command can be used to
5139 invite individuals to the channel but also to manage the invite
5140 list of the channel (to add to and remove from the invite list).
5141 Updated the protocol specs.
5143 * Added new command SILC_COMMAND_BAN that can be used to manage
5144 the ban list of the channel. Updated the protocol specs.
5146 * Removed the channel modes: the SILC_CMODE_BAN and the
5147 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5148 in the CMODE command. The equivalent features are now available
5149 using INVITE and BAN commands. Updated the protocol specs.
5151 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5152 in the network about change in the current ban list. The notify
5153 type is not used by the client.
5155 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5156 support the invite lists.
5158 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Added new function silc_string_regexify that converts string
5161 including wildcard characters into regex string that can
5162 be used by the GNU regex library. Added into the file
5163 lib/silcutil/silcutil.[ch].
5165 Added silc_string_regex_combine to combine to regex strings
5166 into one so that they can be used as one regex string by
5167 the GNU regex library. Added into the file
5168 lib/silcutil/silcutil.[ch].
5170 Added silc_string_regex_match to match two strings. It returns
5171 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5173 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5175 * Imported GNU regex to the soruce tree into lib/contrib.
5176 Fixed some compiler warning from the regex.c.
5178 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * Fixed MOTD command in the server to work in router environment.
5182 * Fixed the MOTD command in the client library to support
5183 the server argument in the command.
5185 * Added `nickname_len' argument to the silc_idlist_add_client
5186 in the server, as the `nickname' argument may be binary data
5189 * Added silc_idlist_get_channels to return all channels from
5192 * Implemented LIST command to the server. Affected file is
5195 * Implemented the LIST command to the client library and on the
5198 * Added [<user count>] argument to the LIST command reply.
5199 With private channels the user count is not shown.
5201 * Updated TODO and README.
5203 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5205 * The client entry's data.registered must be TRUE even with
5206 global client entry on global client list. The data.registered
5207 is used to check whether the client is anymore in the network,
5208 for example with WHOWAS command so it must be valid.
5210 * Fixed the WHOWAS command in the server. It now actually works
5211 in router environment. Added function into silcd/command_reply.c
5212 silc_server_command_reply_whowas_save.
5214 * Added silc_idlist_purge function to the silcd/idlist.c
5215 to periodically purge the ID Cache.
5217 * Fixed INFO command in the server. It works now in router
5218 environment. Added <server name> argument to the INFO command
5219 reply. Updated the protocol specs.
5221 * Fixed minor bug in silc_idcache_purge to not purge if the
5222 expire value is zero.
5224 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5225 they were buggy because of the WHOWAS information.
5227 * Fixed local command MSG to handle the async resolving of
5228 the remote client properly. It used to fail the first MSG.
5229 Affected file silc/local_command.c.
5231 * Added `data_len' field to SilcIDCache context.
5233 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5235 * Update TODO. Todo in commands in the server.
5237 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5239 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5240 used by routers as broadcast packet to inform other routers
5241 about the changed user mode.
5243 Implemented the notify handling in the server. Affected file is
5244 silcd/packet_receive.c. Added the function
5245 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5247 * Added new generic Channel Payload and deprecated the New Channel
5248 Payload. The New Channel Payload is now the generic Channel
5251 * Added new argument `mode' to the silc_server_send_new_channel
5252 as it is required in the Channel Payload now.
5254 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5255 and created a new and real SilChannelPayload to represent the
5256 new generic Channel Payload. Implemented the encode/decode
5257 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5259 * Added silc_server_get_client_channel_list to return the list
5260 of channels the client has joined for WHOIS command reply.
5261 Affected file silcd/server.[ch].
5263 * Implemented the channel list sending in the WHOIS command reply
5264 in server and in the client.
5266 Implemented the channel list displaying on the user interface
5267 as well. Affected file silc/client_ops.c.
5269 * Added silc_channel_payload_parse_list to parse list of Channel
5270 Payloads. It returns SilcDList list of SilcChannelPayloads.
5271 Client for example can use this function to parse the list of
5272 channels it receives in the WHOIS command reply. The caller
5273 must free the list by calling silc_channel_payload_list_free.
5274 Affected files lib/silccore/silcchannel.[ch].
5276 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5278 * Added one new argument <user mode> to the WHOIS command reply
5279 to return the mode of the user in SILC. Updated the protocol
5282 Implemented it to the server and client.
5284 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5286 * Fixed the mode printing on the user interface on joining.
5287 Affected file silc/client_ops.c.
5289 * Implemented the UMODE command and user modes in general to the
5290 client library and to the user interface.
5292 * Implemented the UMODE command to the server.
5294 * The server now sends UNKNOWN_COMMAND error status if client sends
5295 unknown command. Affected file silcd/command.c.
5297 * All server commands now handle the command identifier the right
5298 way when sending the command reply to the client. The client can
5299 use to identify the command replies with the identifier.
5301 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5303 * Added silc_server_get_client_route to resolve the route to
5304 the client indicated by the client ID. Affected file is
5307 * Added silc_server_relay_packet as general function to relay
5308 packet to arbitrary destination. This deprecates functions
5309 like _send_private_message_key, _relay_notify etc. Affected
5310 file is silcd/packet_send.[ch].
5312 Removed silc_server_send_key_agreement,
5313 silc_server_send_private_message_key and
5314 silc_server_packet_relay_notify functions from the file
5315 silcd/packet_send.[ch].
5319 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5320 server. Affected file silcd/packet_receive.[ch].
5322 * Implemented the KILL command to the client. Implemented the
5323 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5324 Affected files lib/silcclient/command[_reply].c and
5325 lib/silcclient/client_notify.c. Implemented the KILL notify
5326 printing in the user inteface.
5328 * Fixed a lot silc_parse_nick memory leaks from the client
5329 library in the file lib/silcclient/command.c.
5331 * Changed the silc_server_send_notify_on_channels's `sender'
5332 argument from SilcSocketConnection to SilcClientEntry to
5333 check the sender as entry and not as connection object and not
5334 to send to the client provided as argument. The affected file
5335 is silcd/packet_send.[ch].
5337 * The notify packets that are destined directly to the client used
5338 to not to be processed by the server. Now changed that and the
5339 server processes all notify packets. After relaying the packet
5340 to the client the notify packet is processed in the server.
5342 * The silc_server_free_client_data now checks whether there is
5343 pending outgoing traffic for the client and purges the data to
5344 the network before removing the client entry.
5346 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5348 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5349 an client is killed from the SILC Network. Updated the protocol
5352 Added new function silc_server_send_notify_killed to the
5353 silcd/packet_send.[ch].
5355 * Added function silc_server_packet_relay_notify to relay notify
5356 packets that are destined directly to a client. In this case
5357 the server does not process the notify packets but merely relays
5358 it to the client. Affected file silcd/packet_send.[ch].
5360 Added also silc_server_packet_process_relay_notify to check
5361 whereto relay the notify. Affected file is
5362 silcd/packet_receive.[ch].
5364 * Implemented the KILL command to the server.
5368 * Added the backup schema desgined last fall to the protocol
5369 specs for everyone to see. The specification is in the
5370 *-spec-xx.txt draft and the packet type definitions for the
5371 backup routers is in *-pp-xx.txt draft. Thusly, added also
5372 new packet type SILC_PACKET_CELL_ROUTERS.
5374 * A big security problem in the implementation discovered. The
5375 signoff of an client did not cause new channel key generation
5376 which it of course should've done. The channel keys must be
5377 always re-generated when client leaves (or signoffs) the channel.
5378 The silc_server_remove_from_channels funtion now handles
5379 the channel key re-generation.
5381 * Added `sender' argument to the silc_server_send_notify_on_channels
5382 to not to send the client provided as argument. Affected file
5383 silcd/packet_send.[ch].
5385 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Implemented OPER and SILCOPER commands into the server and
5390 * Added silc_auth_verify and silc_auth_verify_data to verify
5391 the authentication directly from the authentication payload.
5392 It supports verifying both passphrase and public key based
5393 authentication. Affected file lib/silccore/silcauth.[ch].
5395 * Added `hash' field to the SilcIDListData structure. It is the
5396 hash negotiated in the SKE protocol. Affected file is
5399 * Slight redesigning of the SilcAuthPayload handling routines.
5400 Do not send SilcPKCS but SilcPublicKey as argument.
5402 * Implemented the public key authentication support to the
5403 serverconfig. The public key is loaded from the provided path
5404 and saved as authentication data to void * pointer. Thus,
5405 changed the unsigned char *auth_data to void *auth_data;
5407 * Fixed SHUTDOWN command to send the reply before the server
5408 is shutdown. :) Affected file silcd/command.c.
5410 * Fixed fatal bug in CONNECT command. The hostname was invalid
5411 memory and server crashed. Affected file silcd/command.c.
5413 * Fixed fatal bug in CLOSE command. The server_entry became
5414 invalid but was referenced later in the command. Affected file
5417 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Fixed fatal bug in failure packet handling. Server ignored
5420 the failure and thus crashed when it came.
5424 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5426 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5427 that the command may be executed only once in (about) 2 seconds.
5428 The old SILC_CF_LAG flag is same but allows command bursts up
5429 to five before limiting.
5431 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5432 server code. Various commands now includes the CF_LAG_STRICT
5433 flag to disallow any kind of miss-use of the command.
5435 * Fixed the silc_buffer_unformat to not to allocate any data
5436 if the length of the data is zero. It used to allocate the
5437 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5439 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5441 * Changed the format of AdminConnection configuration section
5442 in the server. Added username of the admin to the format.
5443 Affected files silcd/serverconfig.[ch].
5445 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5446 to return admin configuration data by host, username and/or
5449 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5451 * Implemented WHOWAS command to the server. Added the functions:
5453 silc_server_command_whowas_parse,
5454 silc_server_command_whowas_send_reply,
5455 silc_server_command_whowas_from_client and
5456 silc_server_command_whowas_from_server
5458 * Added <Client ID> argument to the WHOWAS command reply. Updated
5459 the protocol specs accordingly.
5461 * Implemented WHOWAS command and command_reply to the client
5464 Implemented the WHOWAS printing on the user interface.
5466 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5468 * Added new argument to the WHOWAS command reply, the real name.
5469 It is an optional argument. Updated the protocol specs.
5471 * Added SilcIDCacheDestructor callback that is registered when
5472 the SilcIDCache is allocated. The callback is called when
5473 an cache entry in the ID Cache expires, or is purged from the
5474 cache. Added into lib/silccore/idcache.[ch].
5476 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5477 to destruct the client entries when the cache entry expires.
5478 Other ID Cache's in server and in the client library ignores
5481 * If the ID Cache entry's `expire' field is zero then the entry
5482 never expires. Added boolean `expire' argument to the
5483 silc_idcache_add function in the lib/silccore/idcache.[ch].
5484 If it is TRUE the default expiry value is used.
5486 * Added silc_server_free_client_data_timeout that is registered
5487 when client disconnects. By default for 5 minutes we preserve
5488 the client entry for history - for WHOWAS command.
5490 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5492 * Added support to the server to enforce that commands are not
5493 executed more than once in 2 seconds. If server receives
5494 commands from client more frequently, timeout is registered
5495 to process the commands. Affected file silcd/command.c.
5496 Added new function silc_server_command_process_timeout.
5498 * Changed NICK_NOTIFY handling in client library to check that
5499 if the client's nickname was changed, so there is no need to
5500 resolve anything from the server.
5502 * Removed error printing from the WHOIS and IDENTIFY commands.
5503 If error occurs then it is ignored silently in the client library.
5504 The application, however, may map the received error to
5505 human readable error string. The application currently maps
5506 the NO_SUCH_NICKNAME error to string.
5508 * Made the command status message public to the application. Moved
5509 them from lib/silcclient/command_reply.c to
5510 lib/silcclient/command_reply.h. The application can map the
5511 received command status to the string with the
5512 silc_client_command_status_message function.
5514 * Added check to the server to check that client's ID is same
5515 as the Source ID in the packet the client sent. They must
5518 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5520 * Added dist-bzip hook to the Makefile.am to make bzip2
5521 compressed distributions.
5523 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5525 * Server now enforces the maximum length for the nickname and
5526 the channel as protocol specification dictates. 128 bytes for
5527 nickname and 256 bytes for channel name.
5529 * Moved the WHOIS printing to the application. The client libary
5530 does not print out the WHOIS information anymore, the application
5531 must do it. Renamed silc_client_command_reply_whois_print to
5532 the silc_client_command_reply_whois_save.
5534 The client's idle time is also sent to the application now, and
5535 the idle is shown on screen.
5537 * Added silc_client_command_reply_identify_save to save the
5538 received IDENTIFY entries.
5540 * Do not check for channel private keys in message sending and
5541 reception if the channel does not have the PRIVKEY mode set.
5542 Affected file lib/silclient/client_channel.c.
5544 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5547 just surfaced after chaning the JOIN procedure.
5549 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5551 * Added silc_client_get_clients_by_list to get client entries
5552 from Client ID list, that is returned for example by JOIN
5553 and USERS command replies. The application should use this
5554 function for example when JOIN command reply is received to
5555 resolve the clients already on the channel (library does not
5556 do that anymore as USERS command reply is not used in the JOIN
5557 procedure anymore). Affected files lib/silcclient/silcapi.h and
5558 lib/silcclient/idlist.c.
5560 * JOIN command reply and USERS command reply returns now SilcBuffer
5561 pointers instead of unsigned char pointers when returning
5562 the client list and mode list.
5564 * Added <Client ID> argument to the JOIN command reply, mainly
5565 for the server to identify for which client the command was
5566 originally sent. Updated protocol specs accordingly.
5568 * Added SilcDlist private_key pointer to the SilcChannelEntry
5569 in the client to support the channel private keys. Affected
5570 file is lib/silcclient/idlist.h.
5572 * Added SilcChannelPrivateKey argument to the function
5573 silc_client_send_channel_message so that application can choose
5574 to use specific private ke if it wants to. If it is not provided,
5575 the normal channel key is used, unless private keys are set.
5576 In this case the first (key that was added first) is used
5577 as the encryption key.
5579 * Implemented the support for channel private key handling.
5580 Implemented the following functions:
5582 silc_client_add_channel_private_key,
5583 silc_client_del_channel_private_keys,
5584 silc_client_del_channel_private_key,
5585 silc_client_list_channel_private_keys and
5586 silc_client_free_channel_private_keys
5588 Affected file lib/silcclient/client_channel.c.
5590 * Added the support for the private keys in the channel message
5591 sending and encryption and in the message reception and
5592 decryption. Affected funtions are
5593 silc_client_send_channel_message and silc_client_channel_message.
5595 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5597 * Added SKE's key verify callback to the client library's
5598 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5600 * Removed the statement that server (or router) must send USERS
5601 command reply when joining to the channel so that the client
5602 knows who are on the channel. Instead, the client list and
5603 client's mode list is now sent in the JOIN command reply to the
5604 client who joined channel. This is better solution.
5606 * Added function silc_server_get_users_on_channel and function
5607 silc_server_save_users_on_channel to the silcd/server.[ch].
5609 * Removed function silc_server_command_send_users from the
5612 * Do not show topic on the client library anymore. The topic is
5613 sent in the command reply notify to the application and the
5614 application must show the topic now.
5616 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Added client searching by nickname hash into the IDENTIFY and
5619 WHOIS commands in the server as they were clearly missing from
5620 them. Affected file is silcd/command.c.
5622 * Fixed a bug in private message receiving in the client library.
5623 The remote ID was freed and it wasn't supposed, now it is
5626 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5628 * Minor fix to the channel payload; allocate the data area, as it
5629 needs to be of specific length.
5631 * If the key agreement port is zero then the operating
5632 system will define the bound port. Affected files are
5633 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5635 * Added new function silc_channel_payload_decrypt into the file
5636 lib/silccore/silcchannel.[ch].
5638 * Moved the channel message etc, check from silc_packet_decrypt
5639 to applications. The library calls now a generic
5640 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5641 when the packet is either normal or special. This was done to
5642 allow more wide range of checking that was not allowed when
5643 the code was in library. Now applications can do virtually any
5644 checks to the packet and return to the library the decision how
5645 the packet should be processed. Affected files are
5646 lib/silccore/silcpacket.[ch].
5648 Added silc_server_packet_decrypt_check to the server and
5649 silc_client_packet_decrypt_check to the client library.
5651 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5652 to send with specified source and destination information.
5654 * Channel message delivery between routers was broken after the
5655 channel key distribution was fixed earlier. The channel key
5656 was used be to distributed to other routers as well which is not
5657 allowed by the protocol. Now this is fixed and channel keys
5658 really are cell specific and the channel message delivery between
5659 routers comply with the protocol specification.
5661 * Fixed various commands in server to check also the global list
5662 for the channel entry and not just the local list. The affected
5663 file silcd/command.c.
5665 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5667 * Added assert()s to buffer formatting and unformatting routines
5668 to assert (if --enable-debug) when error occurs. Affected
5669 file: lib/silcutil/silcbuffmt.c.
5671 * Changed to auto-reconnect to check whether the remote host is
5672 router and register the re-connect timeout if it is. It used
5673 to check that whether we are normal server, but router must do
5674 auto-reconnect with another router as well. Affected file
5677 * Removed the [<key len>] option from CMODE command as the cipher
5678 name decides the key length, nowadays. See the defined ciphers
5679 from the protocol specification.
5681 * Added [<hmac>] option to the CMODE command to define the HMAC
5682 for the channel. Added SILC_CMODE_HMAC channel mode.
5684 * Added [<hmac>] option for the JOIN command so that user can
5685 select which HMAC is used to compute the MACs of the channel
5688 * Added Hmac field to the Channel Message Payload. The integrity
5689 of plaintext channel messages are now protected by computing
5690 MAC of the message and attaching the MAC to the payload. The
5691 MAC is encrypted. Now, it is clear that this causes some
5692 overhead to the size of the packet but rationale for this is that
5693 now the receiver can verify whether the channel message decrypted
5694 correctly and also when private keys are set for the channel the
5695 receiver can decrypt the packet with several keys and check from
5696 the MAC which key decrypted the message correctly.
5698 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5699 lib/silccrypt/silccipher.[ch].
5701 * Added silc_hash_len to return the digest length into the
5702 lib/silcrypt/silchash.[ch].
5704 * Rewrote parts of Silc Channel Payload interface in the
5705 lib/silccore/silcchannel.[ch]. The encode function now also
5706 encrypts the packet and parse function decrypts it.
5708 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5710 * Fixed a minor formatting bug in the SKE's key material processing.
5711 It actually might have processed the keys wrong way resulting
5714 * Redefined the mandatory HMAC algorithms and added new algorithms.
5715 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5716 and hmac-md5 truncated to 96 bits. The mandatory is now
5717 hmac-sha1-96. Rest are optional (including the one that used
5718 to be mandatory). Rationale for this is that the truncated HMAC
5719 length is sufficient from security point of view and can actually
5720 make the attack against the HMAC harder. Also, the truncated
5721 HMAC causes less overhead to the packets. See the RFC2104 for
5724 * Added new [hmac] configuration section. The SKE used to use
5725 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5726 is of course wrong. The official names that must be proposed in
5727 the SKE are the ones defined in the protocol specification
5728 (hmac-sha1-96 for example). The user can configure any hmac
5729 using any hash function configured in the [hash] section. At
5730 least, the mandatory must be configured.
5732 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5734 * Added HMAC list to the SKE proposal list. It has now both
5735 hash algorithm list and HMAC list. This makes the protocol
5736 incompatible with previous versions. The SKE now seems to work
5737 the way it is supposed to work, for the first time actually.
5739 * Defined plain Hash algorithms to the protocol specification.
5742 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5744 * Implemented support for key agreement packets into the server.
5745 Added functions silc_server_key_agreement and
5746 silc_server_send_key_agreement. Other than these functions,
5747 server has nothing to do with this packet.
5749 * Added support for private message key packets into the server.
5750 Added functions silc_server_private_message_key and
5751 silc_server_send_private_message_key.
5755 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5756 called in the protocol's final callback instead in the END
5757 protocol state. This makes a little more sense and in the same
5758 time in client we can use the same protocol routines for normal
5759 key exchange and to key agreement packet handling as well.
5761 * Added to both client's and server's KE protocol context the
5762 SilcSKEKeyMaterial pointer to save the key material. We will
5763 bring the key material to the protocol's final callback by doing
5764 this. The final callback must free the key material.
5766 * Added SKE's packet_send callback into client's KE protocol
5767 context so that the caller can choose what packet sending function
5768 is used. This way we can use different packet sending when
5769 doing normal SKE when doing key agreement packet handling (in
5770 the key agreement packet handling we do not want to encrypt
5773 * Implemented the responder side of the key agreement routines
5774 in the client. The client can now bind to specified port and
5775 accept incoming key negotiation. The key material is passed
5776 to the application after the protocol is over.
5778 * Implemented the processing of incoming Key Agreement packet
5779 in the client. Added function silc_client_key_agreement to
5782 * Implemented the intiator side of the key agreement routines
5783 in the client. The client can now initiate key agreement with
5784 another remote client. The key material is passed to the
5785 application after the protocol is over.
5787 * Created client_keyagr.c to include all the key agreement
5790 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5791 SILC_TASK_CALLBACK except that it is not static.
5793 * Created client_notify.c and moved the Notify packet handling
5794 from the client.[ch] into that file.
5796 * Created client_prvmsg.c and moved all private message and
5797 private message key routines from the client.[ch] into that file.
5799 * Create client_channel.c and moved all channel message and
5800 channel private key routines from the client.[ch] into that file.
5802 * Changed silc_client_get_client_by_id_resolve to resolve with
5803 WHOIS command instead of IDENTIFY command, in the file
5804 lib/silclient/idlist.c.
5806 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5808 * Implemented the SKE's responder side to the Client library.
5810 * When FAILURE is received to the protocol do not trust it
5811 blindly. Register a timeout to wait whether the remote closes
5812 the connection as it should do it, only after that process the
5813 actual failure. This was changed to both client and server.
5815 * Added client_internal.h to include some of the structures
5816 there instead of client.h in lib/silcclient/.
5818 * Added function silc_task_unregister_by_callback to unregister
5819 timeouts by the callback function.
5821 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5823 * Some "Incomplete WHOIS info" errors has been appearing on the
5824 log files. Took away the entry->userinfo check from WHOIS
5825 reply sending. The entry->userinfo is now " " if client did not
5826 provide one. I thought this was fixed earlier but something
5827 is wrong still. Let's see if the error still appears.
5829 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5831 * Fixed a minor bug in the login when the channel key is
5832 re-generated in the server. It used to generate the key in
5833 wrong order and thus caused problems in the channel traffic.
5835 * Fixed a minor bug in channel key distsribution after
5836 KICK command. The key was not sent to the router even though
5839 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5841 * Added silc_ske_process_key_material_data as generic routine
5842 to process any key material as the SILC protocol dictates. The
5843 function is used by the actual SKE library but can be used by
5844 applications as well. This relates to the private message keys
5845 and the channel private keys since they must be processed the
5846 same way the normal SILC session keys. The protocol dictates
5847 this. Affected files: lib/silcske/silcske.[ch].
5849 Added also silc_ske_free_key_material to free the
5850 SilcSKEKeyMaterial structure.
5852 * Defined silc_cipher_set_key function to set the key for
5853 cipher without using the object's method function. The affected
5854 files: lib/silccrypt/silccipher.[ch].
5856 * Implemented silc silc_client_add_private_message_key,
5857 silc_client_add_private_message_key_ske,
5858 silc_client_del_private_message_key,
5859 silc_client_list_private_message_keys and
5860 silc_client_free_private_message_keys functions in the
5863 Added functions silc_client_send_private_message_key to send
5864 the Private Message Key payload and silc_client_private_message_key
5865 to handle incoming Private Message Key payload.
5867 * Added Cipher field to the Private Message Key payload to set
5868 the cipher to be used. If ignored, the default cipher defined
5869 in the SILC protocol (aes-256-cbc) is used.
5871 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5873 * Removed lib/silcclient/ops.h file.
5875 Redefined parts of the SILC Client Library API. Created new
5876 file silcapi.h that deprecates the ops.h file and defines the
5877 published Client Library API. Defined also private message key
5878 API and channel private key API into the file.
5880 This is the file that the application must include from the
5881 SILC Client Library. Other files need not be included by
5882 the application anymore.
5884 * Added new key_agreement client operation callback and also
5885 defined the Key Agreement library API for the application.
5887 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5889 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5890 is used by clients to request key negotiation between another
5891 client in the SILC network. If the negotiation is started it
5892 is performed using the SKE protocol. The result of the
5893 negotiation, the secret key material, can be used for example
5894 as private message key.
5896 Implemented the Key Agreement payload into the files
5897 lib/silccore/silauth.[ch].
5899 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5901 * Redefined ciphers for the SILC protocol. Added some new ciphers
5902 and defined the key lengths for the algorithms. Changed the
5903 code accordingly. The default key length is now 256 bits.
5905 * Fixed SKE key distribution function silc_ske_process_key_material
5906 when the key length is more than 128 bits. The default key
5907 length in SILC is now 256 bits.
5909 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5910 to indicate unsupported algorithm.
5912 * Renamed rijndael.c to aes.c and all functions as well.
5914 * Fixed a long standing channel key setting bug in client library.
5915 Weird that it has never surfaced before.
5917 * Fixed bug in channel deletion. If the entire channel is removed
5918 then it must also delete the references of the channel entry
5919 from the client's channel list as the client's channel entry and
5920 the channel's client entry share same memory.
5922 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Implemented CONNECT and SHUTDOWN commands in the client.
5926 * Implemented CLOSE command to the client.
5928 * Added the function silc_idlist_find_server_by_name into the
5929 files silcd/idlist.[ch].
5931 Added the function silc_idlist_find_server_by_conn into the
5932 files silcd/idlist.[ch].
5934 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5936 * DIE command was renamed to SHUTDOWN. Updated the both code
5939 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5940 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5942 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5945 * Added function silc_server_create_connection function to create
5946 connection to remote router. My server implementation actually
5947 does not allow router to connect to normal server (it expects
5948 that normal server always initiates the connection to the router)
5949 so the CONNECT command is only good for connecting to another
5952 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5955 or some other client was kicked from the channel.
5957 Implemented the handling of the notify type to both client
5960 Implemented silc_server_send_notify_kicked to send the KICKED
5961 notify. It is used to send it to the server's primary router.
5963 * Implemented the KICK command into server and client.
5965 * Added `query' argument to the silc_idlist_get_client function
5966 to indicate whether to query the client from server or not if
5969 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5970 to indicate that the client is not channel founder.
5974 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5976 * Removed the rng context from SilcPacketContext structure and
5977 changed that the packet routine uses the Global RNG API.
5979 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5981 * Added support for quit message that client can "leave" on the
5982 channel when it quits the SILC. It is ditributed inside the
5983 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5985 Added silc_server_free_client_data that will take the
5986 signoff message as argument.
5988 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5990 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5992 * Updated parts of the protocol specification to keep it up
5995 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5997 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5998 payloads in one packet.
6000 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6001 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6002 use now the new List flag.
6004 * Also deprecated the following packet types: REPLACE_ID,
6005 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6007 * Added list support for Notify packet in server.
6009 * Added silc_server_send_notify_channel_change to send the
6010 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6011 the silc_server_send_replace_id.
6013 * Added silc_server_send_notify_nick_change to send the
6014 NICK_CHANGE notify type. Deprecates the function
6015 silc_server_send_replace_id.
6017 * Added silc_server_send_notify_join to send the JOIN notify type.
6018 Deprecates the function silc_server_send_new_channel_user.
6020 * Added silc_server_send_notify_leave to send LEAVE notify type.
6021 Deprecates the function silc_server_send_remove_channel_user.
6023 * Added silc_server_send_notify_cmode and
6024 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6025 types. Deprecates the silc_server_send_set_mode function.
6027 * Added SERVER_SIGNOFF notify type to indicate that server has
6028 quit. This means that all clients on the channel from that
6029 server will drop. This can be also used when netsplit happens.
6031 Deprecated REMOVE_ID packet type since it is not needed anymore
6034 Added silc_server_send_notify_server_signoff to send the
6035 SERVER_SIGNOFF notify type. Deprecates the function
6036 silc_server_send_remove_id.
6038 Added also silc_server_send_notify_signoff to send the
6039 SIGNOFF notify type.
6041 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6042 SILC protocol from this day on. Changed the protocol
6043 specification as well.
6045 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6046 notify type. It is used between routers to notify about
6047 topic changes on a channel.
6049 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6052 * Partly updated the protocol specification to comply with the
6053 changes now made. It is still though a bit outdated.
6055 * The JOIN notify type now takes one extra argument <Channel ID>.
6056 The packet used to be destined to the channel but now the
6057 JOIN type may be sent as list thus it is impossible to
6058 destine it to any specific channel. By adding this argument
6059 it is again possible.
6061 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6063 * Added CREDITS file. The CHANGES and CREDITS file will appear
6064 in the distribution as well.
6066 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6068 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6069 types in the server's silcd/packet_receive.c.
6071 * Implemented CMODE and CUMODE to work in router environment.
6073 * Fixed minor encoding and decoding buglet from the
6074 lib/silccore/silcmode.c.
6076 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6079 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6081 * Changed all SilcConfigServer* and silc_config_server* to
6082 SilcServerConfig* and silc_server_config*, respectively.
6085 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * Associated the ID (client or server ID) to the Authentication
6088 Payload to avoid any possibility of forging. Updated the
6089 protocol specification and the code accordingly.
6091 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6093 * The RSA key length is now save to the RsaKey context in the
6094 key generation process in lib/silccrypt/rsa.c. The key length
6095 is now used to figure out the maximum size of the block allowed
6096 to be encrypted/signed.
6098 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6099 is equivalent to the silc_mp_mp2bin but does not allocate any
6102 * Changed silc_mp_mp2bin API to take length argument. If it is
6103 non-zero then the buffer is allocated that large. If zero, then
6104 the size is approximated using silc_mp_sizeinbase, which however
6107 * Created Global RNG API which is global RNG that application can
6108 initialize. After initializing, any routine anywhere in the
6109 code (including library) can use RNG without allocating a new
6110 RNG object. This was done to allow this sort of use of the
6111 RNG in code that has no chance to allocate RNG object. All
6112 applications currently allocate this and many routines in the
6113 library use this. Affected file lib/silccrypt/silcrng.[ch].
6115 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6116 it to use the Global RNG API.
6118 * Defined Authentication Payload into protocol specification that
6119 is used during SILC session to authenticate entities. It is
6120 used for example by client to authenticate itself to the server
6121 to obtain server operator privileges.
6123 Implemented this payload into the lib/silccore/silcauth.[ch].
6124 Implemented also routines for public key based authentication
6125 as the new protocol specification dictates.
6127 Moved definitions of different authentication methods from
6128 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6130 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6131 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6132 silc_pkcs_verify_with_hash functions into the file
6133 lib/silccrypt/silcpkcs.[ch].
6135 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6137 * The client entry's userinfo pointer must be always valid.
6138 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6139 will fail since it requires the userinfo. Now, the userinfo
6140 is allocated as "" if actual userinfo does not exist. Actually,
6141 it must exist and it is totally Ok to drop client connections
6142 that does not announce the userinfo. However, we will make
6143 this workaround for now.
6145 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6146 to return the remote port by socket.
6148 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6150 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6151 SILC_SERVER_PENDING_EXEC and added an new macro
6152 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6153 data or when error occurs while processing the pending command.
6155 Added new argument `destructor' into silc_server_command_pending
6156 and to the SilcServerCommandPending object. This destructor is
6157 now called after calling the pending callback or if error occurs
6158 immediately. If error occurs the actual pending callback won't
6159 be called at all - only the destructor. The destructor may be
6160 NULL if destructor is not needed.
6162 All this applies for client library code as well. Similar
6163 changes were made there as well for the pending commands.
6165 In the client, the application must now allocate the
6166 SilcClientCommandContext with the silc_client_command_alloc
6169 * Added reference counter to the SilcServerCommandContext. Added
6170 function silc_server_command_alloc and silc_server_command_dup
6173 Same type of functions added to the client library for the same
6176 * Removed the cmd_ident from IDListData away since it is now
6177 global for all connections. It is the command identifier used
6178 in command sending and with pending commands. The affected file
6181 * Added reference counter to the SilcSocketConnection objecet to
6182 indicate the usage count of the object. The object won't be
6183 freed untill the reference counter hits zero. Currently only
6184 server uses this, and client ignores it. The client must be
6185 set to use this too later. The affected files are
6186 lib/silccore/silcsockconn.[ch]. Added also the function
6187 silc_socket_dup to increase the reference counter.
6189 This was mainly added because it is possible that the socket
6190 is removed underneath of pending command or other async
6191 operation. Now it won't be free'd and proper DISCONNECTING
6192 flags, etc. can be set to avoid sending data to connection that
6193 is not valid anymore.
6195 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6196 the connection. After that it sets SILC_SET_DISCONNECTED.
6197 It is, however, possible that the socket data is not still freed.
6198 The silc_server_packet_process now checks that data is not
6199 read or written to connection that is DISCONNECTED. The socket
6200 get's freed when the reference counter hits zero.
6202 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6204 * Changed the client operation API: channel_message operation's
6205 `sender' is now the client entry of the sender, not the nickname
6206 and the `channel' is the channel entry, not the channel name.
6208 In the private_message operation the `sender' is now also the
6209 client entry of the sender not the nickname.
6211 Affected file is lib/silcclient/ops.h and all applications
6212 using the client operations.
6214 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6216 * Moved the calling of ops->connect() from connect_to_server_final
6217 into receive_new_id functin since that is the point when the
6218 client is actually allowed to send traffic to network. The
6219 affected file is lib/silcclient/client.c.
6221 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6223 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6224 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6225 (if needs broadcasting) instead of broadcasting the packets one
6226 by one which would make a burst in the network traffic.
6228 * Added `broadcast' argument to the functions in silcd/server.[ch]
6229 silc_server_create_new_channel[_with_id] to indicate whether
6230 to send New Channel packet to primary router.
6232 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6234 * Added new function into the silcd/server.[ch] files:
6235 silc_server_create_new_channel_with_id to create new channel with
6236 already existing Channel ID.
6238 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6239 lib/silccore/silcpacket.h. This packet is used t send list of
6240 Set Mode payloads inside one packet. Server uses this to set
6241 the modes for the channels and clients on those channels, that it
6242 announced to the router when it connected to it. The protocol
6243 specification has been updated accordingly.
6245 * The silc_server_new_channel did not handle the packet coming
6246 from normal server as it normally does not send that. However,
6247 when it announces its channels it does send it. Implemented
6248 the support for that.
6250 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6251 into the file lib/silccore/id.h.
6253 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6255 * Fixed memory leaks in the functions silc_idlist_del_client,
6256 silc_idlist_del_channel and silc_idlist_del_server in the file
6257 silcd/idlist.c. All of those leaked like a sieve.
6259 * Fixed some small memory leaks in the client's function
6260 silc_client_notify_by_server.
6262 * Added functions into silcd/server.c: silc_server_announce_clients,
6263 silc_server_announce_channels and silc_server_announce_server.
6264 These functions are used by normal and router server to announce
6265 to its primary router about clients, channels and servers (when
6266 router) that we own. This is done after we've connected to the
6269 These functions effectively implements the following packet types:
6270 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6271 and SILC_PACKET_NEW_ID_LIST.
6273 * Added new functions into the silcd/packet_receive.[ch]:
6274 silc_server_new_id_list, silc_server_new_channel_list and
6275 silc_server_new_channel_user_list to handle the incoming
6276 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6278 * Added support of changing Channel ID in the function
6279 silc_server_replace_id. If the server that announces a channel
6280 to the router already exists in the router (with same name but
6281 with different Channel ID), router is responsible to send
6282 Replace ID packet to the server and force the server to change
6283 the Channel ID to the one router has.
6285 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6286 client that the Channel ID has been changed by the router. The
6287 normal server sends this to the client. Client must start using
6288 the new Channel ID as the channel's ID.
6290 Implemented handling of this new type into lib/silcclient/client.c
6291 into the function silc_client_notify_by_server.
6293 * Added new function silc_idlist_replace_channel_id into the files
6294 silcd/idlist.[ch] to replace the Channel ID.
6296 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6298 * Call silc_server_command_identify_check always when processing
6299 the IDENTIFY command in silcd/command.c
6301 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6303 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6304 send keepalive packets. The packet can be sent by clients,
6305 servers and routers.
6307 Added function silc_socket_set_heartbeat into the file
6308 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6309 If not set, the heartbeat is not performed. The actual
6310 heartbeat is implemented in the low level socket connection
6311 library. However, application is responsible of actually
6314 Added silc_server_send_heartbeat to send the actual heartbeat
6315 packet into silcd/packet_send.[ch]. Server now performs
6316 keepalive with all connections.
6318 * Added silc_task_get_first function into lib/silcutil/silctask.c
6319 to return the timeout task with shortest timeout. There was a bug
6320 in task unregistration that caused problems. TODO has been
6321 updated to include that task system must be rewritten.
6323 * The client library will now resolve the client information when
6324 receiving JOIN notify from server for client that we know but
6325 have incomplete information.
6327 * Rewrote parts of silc_server_remove_from_channels and
6328 silc_server_remove_from_one_channel as they did not remove the
6329 channel in some circumstances even though they should've.
6331 * Encryption problem encountered in server:
6333 The LEAVE command used to send the Channel Key packet to the
6334 router immediately after generating it. However, the code
6335 had earlier sent Remove Channel user packet but not immediately,
6336 ie. it was put to queue. The order of packets in the router
6337 was that Channel Key packet was first and Remove Channel User
6338 packet was second, even though they were encrypted in the
6339 reverse order. For this reason, MAC check failed. Now, this
6340 is fixed by not sending the Channel Key packet immediately but
6341 putting it to queue. However, this is more fundamental problem:
6342 packets that are in queue should actually not be encrypted
6343 because packets that are sent immediately gets encrypted
6344 actually with wrong IV (and thus MAC check fails). So, packets
6345 that are in queue should be encrypted when they are sent to
6346 the wire and not when they put to the queue.
6348 However, the problem is that the current system has not been
6349 designed to work that way. Instead, the packet is encrypted
6350 as soon as possible and left to the queue. The queue is then
6351 just purged into wire. There won't be any fixes for this
6352 any time soon. So, the current semantic for packet sending
6355 o If you send packet to remote host and do not force the send
6356 (the packet will be in queue) then all subsequent packets to the
6357 same remote host must also be put to the queue. Only after the
6358 queue has been purged is it safe again to force the packet
6361 o If you send all packets immediately then it safe to send
6362 any of subsequent packets through the queue, however, after
6363 the first packet is put to queue then any subsequent packets
6364 must also be put to the queue.
6366 Follow these rules and everything works fine.
6368 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6370 * Added new function silc_server_remove_clients_by_server to
6371 remove all client entries from ID list when the server connection
6372 is lost. In this case it is also important to invalidate all
6373 client entires as they hold the invalid server entry. This
6374 fixes fatal bug when server has lost connection and will reconnect
6377 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6379 * Made some sanity checks to silc_server_daemonise like to check
6380 whether the requested user and group actually exists.
6382 * Added sanity check to SKE's silc_ske_responder_finish to check
6383 that the public and private key actually is valid.
6385 * Invalidate the client's nickname when receiving Replace ID
6386 packet and the Client ID is being replaced. This means that the
6387 server will query the nickname if someone needs it (client)
6390 * Sort the ID Cache in client library when the ID Cache data
6391 has changed (needs sorting).
6393 * Do not allow for SILC client to create several connections to
6394 several servers. The client does not support windows right now
6395 and generating multiple connections causes weird behaviour.
6397 Irssi-silc client does support windows and can handle several
6398 connections without problems, see: www.irssi.org and SILC plugin.
6400 * Fixed some places where client was added to the IDList. The
6401 rule of thumb is following (in order to get everything right):
6402 If the client is directly connected local client then the
6403 `connection' argument must be set and `router' argument must be
6404 NULL to silc_idlist_add_client function. If the client is not
6405 directly connected client then the `router' argument must
6406 bet set and the `connection' argument must be NULL to the
6407 silc_idlist_add_client function.
6409 * The funtion silc_server_packet_send_local_channel actually did
6410 not check whether the client was locally connected or not. It
6411 does that now. Fixed a bug related to LEAVE command.
6413 * Fixed Remove Channel User payload parsing bug in server's
6414 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6416 * The server's silc_server_save_channel_key now checks also the
6417 global ID list for the channel as it might not be in the local
6418 list. Fixed a bug related to LEAVE command.
6420 * Is this the end of the [<unknown>] buglet that has been lurking
6421 around for a long time? A little for loop fix in server's
6422 silc_server_command_whois_parse that is used by both IDENTIFY
6423 and WHOIS command. At least, this was a clear bug and a cause
6424 of one type of [<unknown>] buglet.
6426 * WHOIS and IDENTIFY commands call the function
6427 silc_server_command_[whois/identify]_check function even if
6428 we are not router server.
6430 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6432 * Added --with-gmp configuration option. If set the GMP
6433 is always compiled in the SILC source tree. If not set then
6434 it is checked whether the system has the GMP3 installed. If
6435 it has then the GMP won't be compiled (the system's headers
6436 and library is used), if it doesn't have it then the GMP is
6437 compiled in the SILC source tree.
6439 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * Changed RSA private exponent generation to what PKCS #1
6442 suggests. We try to find the smallest possible d by doing
6443 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6444 not security fix but optimization.
6446 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6448 * Added new config entry [Identity] to fork the server and run
6449 it as specific user and group. A patch from Bostik.
6451 * Imported Dotconf configuration library into lib/dotconf.
6452 This will be used to create the SILC configuration files later.
6453 It will appear in the distsribution after this commit.
6455 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6457 * A big code auditing weekend happening. Auditing code for
6458 obvious mistakes, bugs and errors. Also, removing any code
6461 Removed files for being obsolete:
6463 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6464 inline in the file lib/silcutil/silcbuffer.h)
6466 o lib/silcutil/silcbufutil.c (the header has inline versions)
6468 Changed code to fix possible error conditions:
6470 o The buffer formatting routines now check that the destination
6471 buffer really has enough space to add the data. This applies for
6472 both buffer formatting and unformatting
6473 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6474 unformatting was changed to accomodate following rules:
6475 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6476 sent to the function while XXX_*STRING will not allocate or copy
6477 the data into the buffer. Instead it sets the pointer from the
6478 buffer into the pointer sent as argument (XXX_*STRING used to
6479 require that the pointer must be allocated already). This change
6480 makes this whole thing a bit more consistent and more optimized
6481 (note that the data returned in the unformatting with XXX_*STRING
6482 must not be freed now). The routines return now -1 on error.
6484 o Tried to find all code that use buffer_format and buffer_unformat
6485 and added return value checking to prevent formatting and
6486 especially unformatting errors and possible subsequent fatal
6489 o Changed ske->x and ske->KEY to mallocated pointers in
6490 lib/silcske/silcske.h. Fixed possible data and memory leak.
6492 o Added return value checking to all *_parse* functions. Fixed
6493 many memory leaks as well.
6495 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6496 so that buffer overflows would not happen. All code now also
6497 checks the return value as it can fail.
6499 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6501 * Added reconnection support to server if the normal server looses
6502 its connection to the router (for example if router is rebooted).
6503 The server performs normal reconnection strategy implemented
6504 to the server. Affected file silcd/server.c.
6506 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6508 * Added new packet type SILC_PACKET_SET_MODE that is used to
6509 distribute the information about changed modes (for clients,
6510 channels and clients channel modes) to all routers in the
6511 network. Updated the protocol specification accordingly.
6513 Added functions into silcd/packet_send.c and
6514 silcd/packet_receive.c: silc_server_send_set_mode,
6515 silc_server_set_mode.
6517 Added new files silcmode.[ch] into lib/silccore that implements
6518 the encoding and decoding of Set Mode Payload. Added new type
6519 SilcSetModePayload. Moved the definitions of different modes
6520 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6522 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6524 * Oops, a little mistake in server's connection authentication
6525 protocol. The protocol is not ended with FAILURE but with
6526 SUCCESS if the authentication is Ok. :) Affected file is
6529 * Implemented NICK_CHANGE notify handling in server in the file
6530 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6531 the local clients on the channel. After the changing nickname
6532 in router environment snhould work and the [<unknown>] nickname
6533 should appear no more.
6535 The silc_server_replace_id function that receives the Replace ID
6536 payload now sends the NICK_CHANGE notify type also in the file
6537 silcd/packet_receive.c
6539 * Changed WHOIS and IDENTIFY command to support the maximum amount
6540 of arguments defined in protocol specs (3328 arguments). This
6541 fixed a bug that caused problems when there were more than three
6544 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6546 * Added extra parameter, command identifier, to the
6547 silc_client_send_command so that explicit command identifier
6550 Changed that ID list routines uses specific command identifier
6551 when sending WHOIS/IDENTIFY requests to the server so that they
6552 can be identified when the reply comes back.
6554 Affected files lib/silcclient/command.[ch],
6555 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6557 * Added `sender' argument to silc_server_packet_send_to_channel
6558 to indicaet the sender who originally sent the packet to us
6559 that we are now re-sending. Ignored if NULL. Affected file
6560 silcd/packet_send.[ch].
6562 * Added some server statistics support in silcd/server_internal.h
6563 SilcServerStatistics structure and around the server code. Also
6564 send some nice statistics information when client is connecting
6567 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6569 * Fixed channel ID decoding in server's JOIN command reply in
6570 silcd/command_reply.c
6572 * Fixed braodcasting of replace ID payload to not to send it if
6573 we are standalone server in silcd/packet_receive.c.
6575 * Fixed all channel message sending routines to not to send
6576 packets to clients that has router set, since they are routed
6577 separately in the same function earlier. Affects file
6578 silcd/packet_send.c and all channel packet sending functions.
6580 * In USERS reply, res_argv[i] are not allocated, the table
6581 is allocated. Thus changed that free the table, not its
6584 * In server's whois_check and identify_check if the client is
6585 locally connected do not send any WHOIS commands - they are not
6588 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * Fixed some minor bugs in client when sending WHOIS command. The
6591 arguments was in wrong order.
6593 * Removed statis function add_to_channel from server in
6594 silcd/command.c that was previously used with the joining but
6597 * Tested USERS command in router environment successfully with two
6598 routers, two servers and two clients.
6600 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6602 * Reorganized the USERS command and command reply in client library
6603 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6604 When the command is given by user we register a pending command
6605 callback that will reprocess the command after the reply has been
6606 received from the server. When reprocessing the packet we then
6607 display the information. Thus, the USERS information is displayed
6608 now in the command callback instead of in the command reply
6609 callback. The processing of the command is same as previously
6610 when server has sent the command reply in the JOINing process.
6612 * Added to USERS command in silcd/command_reply.c to join the client,
6613 we didn't use to know about, to the channel after we've created
6614 a client entry for it. Also, for clienet we did know already still
6615 check whether it is on the channel or not and add it if not.
6617 * Removed silc_server_command_join_notify as the function and its
6620 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6622 * Changed the client's pending command handling to the same as the
6623 server's pending command handling. It is also now possible to
6624 execute command reply functions from other command reply
6625 function as the function callbacks for commands and command
6626 replies are one and same. The pending commands are not static
6627 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6628 in client connection context. Thus, pending commands are server
6629 connection specific as it is convenient.
6631 Changed the function silc_client_command_pending and
6632 silc_client_command_pending_del and added new function
6633 silc_client_command_pending_check. Removed the
6634 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6637 * Added cmd_ident, current command identifier, to the client
6638 connection context in lib/silcclient/client.h to keep track on
6639 command identifiers used in command sending. Client's command reply
6640 function handling now supports the mandatory command identifiers.
6642 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6643 funtions in client to fully support pending command callbacks.
6645 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6646 as one of the arguments to the application in the command reply
6649 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6650 before first releasing SILC but came back. Now it is removed again
6651 and should come back nomore. The FORWARDED flag was used only
6652 by the JOINing procedure by forwarding the command packet to router.
6653 Now, the JOINing procedure has been changed to more generic (due
6654 to various router environment issues) and FORWARDED is not needed
6655 anymore for anything. The protocol specification is yet to be
6658 Now, removed silc_server_packet_forward from server and the flag
6659 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6661 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6663 * Renamed NAMES command to USERS command. The NAMES was named that
6664 due to historical reasons. Now it is renamed. Also, rewrote
6665 parts of the USERS command. The nickname list is not sent anymore
6666 by the server. Only Client ID and mode lists are sent in the USERS
6667 command. Changed this also to the protocol specification.
6669 The client now resolves the names and stuff after it receives
6670 the USERS list from the server when joining to the channel.
6672 * WHOIS and IDENTIFY commands has been changed to support multiple
6673 Client ID's per command. One can now search for multiple users
6674 in the network by sending only one WHOIS or IDENTIFY command.
6675 Changed the code and the protocol specifications.
6677 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6678 uses silc_server_command_whois_parse to parse the request. */
6680 * If normal server, do not parse the WHOIS and IDENTIFY requests
6681 before sending it to the router. Saves some time.
6683 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6685 * Fixed JOIN command on client library. Wrong number of arguments
6686 used to crash the client.
6688 * Added silc_server_channel_has_global function to check whether
6689 channel has global users or not.
6691 * Added silc_server_channel_has_local function to check whether channel
6692 has locally connected clients on the channel.
6694 * The silc_server_remove_from_one_channel now checks whether the
6695 channel has global users or not after given client was removed from
6696 the channel. It also checks whether the channel has local clients
6697 on the channel anymore. If it does not have then the channel entry
6698 is removed as it is not needed anymore.
6700 * The silc_server_notify now checks on JOIN notify whether the joining
6701 client is one of locally connected or global. If it is global then
6702 the channel has now global users on the channel and that is marked
6703 to the channel entry. Also, it now saves the global client to
6704 global list who is joining and JOINs it to the channel. This is
6705 for normal server, that is.
6707 Changed silc_server_send_notify_on_channel,
6708 silc_server_packet_relay_to_channel and
6709 silc_server_packet_send_to_channel check if we are normal server
6710 and client has router set (ie. global client) do not send the
6711 message to that client, as it is already routed to our router.
6713 * Implemented LEAVE notify type handling in silc_server_notify
6716 * Tested LEAVE command in router environment successfully. Tested
6717 with two routers, two servers and two clients.
6721 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6723 * Implemented SIGNOFF notify type handling in silc_server_notify
6726 * silc_server_remove_id now removes the client entry from all channels
6727 it has joined and thusly sends SIGNOFF notify type.
6729 * Rewrote the NAMES list generation in server by removing two excess
6730 loops. The lists are created now inside one loop.
6732 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6734 * silc_server_remove_channel_user checks now also global list
6735 for channel and client.
6737 * silc_server_new_channel_user checks now both local and global
6738 list for channel and client. Fixed a bug in client id decoding.
6739 Used to decode wrong buffer.
6741 * silc_server_channel_message checks now both local and global
6742 list for channel entry.
6744 * Tested channel joining (hence JOIN) in router environment
6745 successfully. Tested with two routers, two servers and two
6748 * Tested channel message sending in router environment successfully.
6750 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6752 * Added silc_server_save_channel_key into server.[ch] to save the
6753 received channel key in Channel Key payload processing. It is
6754 also used in JOIN command reply handling.
6756 Equivalent function silc_client_save_channel_key added into
6757 client.[ch] into client library.
6759 * Changed JOIN command reply to send information whether the channel
6760 was created or not (is existing already) and the channel key
6761 payload. Changed protocol specs accordingly.
6763 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6764 the request was sent by ID and not by nickname. Crashed on
6767 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6769 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6770 now correctly save the received data.
6772 * silc_server_free_sock_user_data now notifies routers in the
6773 network about entities leaving the network.
6775 At the same time implemented functions silc_server_remove_id
6776 and silc_server_send_remove_id to receive and send REMOVE_ID
6777 packets. The packet is used to notify routers in the network
6778 about leaving entities. The ID removed will become invalid in
6781 * Added function silc_idlist_del_server into server. Removes and
6782 free's server entry from ID list.
6784 * silc_server_private_message function now checks, if we are router,
6785 that the destination ID really is valid ID, naturally.
6787 * In router when NEW_ID packet is received (for new client) the
6788 hash of the Client ID is saved in the ID Cache but the
6789 client->nickname is set to NULL, instead of putting the hash
6792 IDENTIFY command now also checks that client->nickname must be
6793 valid. If it is not if will request the data from the server who
6794 owns the client. Added new function
6795 silc_server_command_identify_check.
6797 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6798 to set the command to already allocated Command Payload.
6800 * Tested private message sending in router environment with two
6801 routers, two servers and two clients. Fixed minor bugs and now
6804 * Fixed segfault from client's NAMES command. Used to crash if
6807 * Forwarded packets must not be routed even if it is not destined
6808 to the receiver. Changed server code comply with this.
6810 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6812 * Added `require_reverse_mapping' boolean value to ServerParams
6813 structure. If TRUE (not default) the server will require that
6814 the connecting host has fully qualified domain name.
6816 If the reverse mapping is not required and hostname could not be
6817 found the IP address is used as hostname.
6819 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6821 * Implemented version string checking to both client and server.
6822 The check is incomplete currently due to the abnormal version
6823 strings used in development version of SILC.
6825 * Changed all command functions in server to use the new
6828 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6830 * Changed char *data to unsigned char *data in ID Cache system to
6831 support binary data as ID Cache data. Changed code to support
6832 binary data in lib/silccore/idcache.c.
6834 * Renamed silc_server_packet_relay_command_reply to
6835 silc_server_command_reply as it is normal packet receiving
6836 function. Rewrote the function to accept command replys for
6837 servers and not only for clients.
6839 * Mark remote router always as registered server if we are connecting
6840 to it. Otherwise, commands sent by the router to us are ignored.
6842 * All ID List find routines now returns the ID Cache Entry pointer
6843 as well if requested.
6845 * WHOIS command works now in router environment, tested with two
6846 routers, two servers and two clients.
6848 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6849 in router environment (as it is almost equivalent to WHOIS) but
6850 hasn't been tested thoroughly. Added new functions:
6852 silc_server_command_identify_parse
6853 silc_server_command_identify_send_reply
6854 silc_server_command_identify_from_client
6855 silc_server_command_identify_from_server
6857 * Disabled route cache adding because adding two different ID's with
6858 same IP replaces the old cache entry thus giving wrong route.
6859 The entry->router->connection is always the fastest route anyway
6860 so route cache may not be needed. Of course, new routes maybe
6861 established after receiving the ID when the entry->router->connection
6862 might not be anymore the most optimal.
6864 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6866 * Add route cache for received ID for fast routing.
6868 * Added silc_server_packet_route to route received packet on router
6869 that is not destined to us.
6871 * Renamed silc_server_get_route to silc_server_route_get.
6873 * Added id_string and id_string_len fields into SilcServer to
6874 include encoded ServerID for fast comparing without excess
6875 encoding of the ID's.
6877 * Cleaned up WHOIS command on server side. Added following static
6880 silc_server_command_whois_parse
6881 silc_server_command_whois_check
6882 silc_server_command_whois_send_reply
6883 silc_server_command_whois_from_client
6884 silc_server_command_whois_from_server
6886 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6887 arguments in command replies. All command functions should be
6888 updated to use this macro.
6890 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6892 * Minor typo fixes on command reply handling on server.
6894 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6896 * Added silc_server_command_add_to_channel internal routine to add
6897 the client to the channel after router has created the channel and
6898 sent command reply to the server.
6900 * Added generic silc_server_send_command to send any command from
6903 * Use static buffer with ID rendering instead of duplicating data.
6905 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6907 * Fixed a channel user mode bug when joining to a channel server gave
6908 everybody channel founder rights, oops.
6910 * We mark ourselves as the router of the incoming server connection
6911 if we are router ourselves. This way we can check in some packet
6912 sending functions whether it is locally connected server. For
6913 incoming router connections we put NULL.
6915 * For router sending packets locally means now always sending the
6916 packet cell wide; to local clients and local servers. For normal
6917 server sending packet locally means sending it to only local
6920 * Fixed the JOIN command to really work in router environment. If the
6921 channel is created it is always created by the router. Router is
6922 also responsible of making the initial joining to the channel,
6923 sending JOIN notify to the sending server and distributing
6924 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6925 does not exist server doesn't do anything else but forward the
6926 command to the router which performs everything.
6928 * Added silc_server_send_channel_key function to send the Channel Key
6931 * Added silc_server_create_channel_key to create new channel key. The
6932 channel key is now re-generated everytime someone joins or leaves
6933 a channel, as protocol dictates. Note: channel->key_len is the
6936 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6938 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6939 packet_receive.[ch] to separate packet sending and receiving
6940 routines. The server.[ch] now includes everything else including
6941 actual packet processing (writing and reading data) and other
6944 Renamed silc_server_private_message_send_internal to
6945 silc_server_send_private_message. The routine is still though
6946 used only to relay private messages as server does not send
6947 private messages itself.
6949 Renamed silc_server_new_channel to silc_server_create_new_channel
6950 and added new function sicl_server_new_channel that handles the
6951 incoming New Channel packet. Added also new sending function
6952 silc_server_send_new_channel to send New Channel Payload.
6954 * Added new function silc_server_notify to process incoming notify
6955 packet to the server/router. Server may then relay the notify
6956 to clients if needed.
6958 * Added new function silc_server_new_channel_user to process incoming
6959 New Channel User packet. Router will redistribute the packet and
6960 send JOIN notify to its local clients and locally connected servers
6961 if needed. Normal server will send JOIN notify to its local client
6962 on same channel when received this packet. Added also corresponding
6963 sending function silc_server_send_new_channel_user to sent the
6966 * Added boolean route argument to send_notif_to_channel and
6967 packet_send_to_channel functions to attempt to route the packet
6968 if it is TRUE and send only locally if it is FALSE.
6970 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6972 * silc_server_replace_id now broadcasts the received replace ID
6973 packet if it is not broadcast packet already. The router must
6974 broadcast to inform other routers about changed ID.
6976 * Added backpointer to server's router into SilcServer context in
6977 silcd/server_internal.h.
6979 * Fixed silc_server_packet_broadcast to send correct broadcast
6982 * The channel key is now distributed to the local client as soon
6983 as it is received from the router (in router environment) so that
6984 no other packet may be sent for the channel until client has
6987 * silc_server_remove_channel_user now broadcasts the received
6988 Remove Channel User packet if it is not broadcast packet already.
6989 The router must broadcast to inform other routers about removed
6992 * Added users field into SilcPacketContext that is a reference count
6993 of the context. One can increase the reference count by calling
6994 silc_packet_context_dup which is now changed to just increase the
6995 reference count instead of duplicating the data. The reference
6996 count is decresed by calling silc_packet_context_free that will
6997 free the data after the reference count hits zero.
6999 For now on the packet context and everything allocated into it
7000 (including the raw packet from network) must be freed by calling
7001 the new silc_packet_context_free function. Added also new function
7002 silc_packet_context_alloc that must be used now to allocate the
7003 context. This also means that if a routine is asynchronous from
7004 silc_[client/server]_packet_parse_type the packet context must
7005 be duplicated by calling silc_packet_context_dup. Otherwise it
7006 gets free'd after silc_[client/server]_packet_parse_type returns.
7007 Also, one must remember that if packet is duplicated then its
7008 reference count must be decresed by calling the free function as
7009 many times as it was duplicated.
7011 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7012 from both client and server.
7014 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7016 * Made joining to a channel working in router environment.
7018 * Cleaned up JOIN command on server side and create function
7019 silc_server_command_join_channel internal routine to make the
7022 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7024 * Changed silc_command_pending list to SilcDList. Also, added
7025 `ident' field to SilcServerCommandPending structure to identify
7026 the reply and to call correct callback.
7028 Added silc_server_command_pending_check function to replace the
7029 corresnponding macro. The silc_command_pending list is not
7032 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7033 to set identifier to previously allocated Command Payload. It
7034 is used to set identifier for command when resending Command
7037 * Added silc_command_payload_encode_payload to encode Command
7038 Payload buffer from SilcCommandPayload structure.
7040 * Added silc_argument_payload_encode_payload to encode Argument
7041 payload buffer from SilcArgumentPayload structure.
7043 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7045 * Changed WHOIS command to support router connection on server side.
7046 The whois request is always sent to router unless the server is
7047 standalone server. After server has received the reply from the
7048 router will it send the reply to the client.
7050 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7051 broadcast received broadcast packet. The function is used only
7052 by router. The broadcast packet is always sent to the router's
7055 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7056 render given ID to printable string, for log files for example.
7058 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7060 * Made basic router to router connections working. At least they
7061 can now connect to each other but nothing really works the way
7062 they are supposed - yet.
7064 * Added new initiator token to RouterConnection configuration
7065 file in silcd/serverconfig.[ch]. It is used to tell whether we
7066 are the initiator to the remote router or whether we'll expect
7067 the other end to connect.
7069 * Moved registering of listener task to silc_server_init, hence
7070 the server starts listenning as soon as it is run, even if it
7071 does not have connections to other routers. Let's see how well
7074 * Changed default connection retry timeouts for more suitable in
7077 * Removed cipher and such arguments from silc_idlist_add_client
7078 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7079 Added new function silc_idlist_add_data to add the keys and stuff
7082 * Added SilcIDListData structure and added it to SilcClientEntry
7083 and SilcServerEntry as their first field in the structure. This
7084 way we can explicitly cast the ID entries to the SilcIDListData
7085 structure and get common data for the entries. In past, we had
7086 to first check what type of connection it is and then cast it to
7087 correct ID entry type. Now, we can directly cast the opaque
7088 pointer to the SilcIDListData (no matter what ID entry it actually
7089 is) and get the data needed.
7091 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7093 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7094 in some circumstances even if threre were timeout tasks, though not
7095 IO tasks, but tasks anyway. Now fixed.
7097 * Defined SilcServerConnection structure to hold connection specific
7098 stuff about directly connected servers and routers. The definition
7099 is currently in silcd/server_internal.h. I thought about having
7100 a bit more important role fro this struct but for now it is used
7101 only when connecting to other server (or router actually).
7103 * Added connecting retry support in server when connecting to
7104 router(s). The retry feature implement exponential backoff
7105 algorithm. Also, added SilcServerParams structure to hold default
7106 parameters for server. For now, it include these retry settings
7107 and are hard coded. After server is moded to be as Silc Server
7108 Library this structure will be more important.
7110 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7112 * Changed client librarys channel->clients table to SilcList and
7113 changed code accordingly.
7115 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7117 * Changed client's channel table to SilcList and changed code
7118 accordingly. Also changed SilcChannelClientEntry to include back-
7119 pointer to the channel so that client entry can use that structure
7120 as list as well and we have fast cross-reference to the channel.
7121 This change dramatically decreased the complexity of channel
7122 handling with client entry and vice versa (removed one extra
7123 loop when searching for channel entry from many functions).
7125 * Changed server->sim from table to SilcDList and changed code
7128 * NAMES command can now be used from user interface. It will show
7129 the user list on the channel, neatly.
7131 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7132 Code now saves realname of the user if it becomes available.
7134 * Renamed configure.in to configure.in.pre and made ./prepare
7135 script to automatically add correct version string to
7136 configure.in which it creates from configure.in.pre.
7138 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7140 * NAMES command reply now shows users mode with the nickname when
7143 * Moved silc_client_ch[u]mode[_char] functions from
7144 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7145 place sucks, they are utility functions and should be in some
7148 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7150 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7153 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7157 * Added TRQ (efficient deque and list library) into lib/trq. This is
7158 a very good list library that is currently used in the SILC. Defined
7159 SilcList API over the library because I didn't like the API very
7160 much. See lib/trq/silclist.h for the API and examples of how to
7161 use the API. Fixed various places in the code to use the new
7162 SilcList API. The SilcList is meant for lists that has a structure
7163 already defined as a list. It is not suitable to add just some
7164 context to the list (in TRQ, the context is the list actually).
7166 So, I defined SilcDList that can be used for the purpose where
7167 predefined list structure does not exit. This can be used as
7168 such list. Now some context just can be added to the SilcDList.
7169 Currently this list is not used in the SILC just yet, though there
7170 are a lot places where this can replace dynamically allocated
7171 tables and I will fix these places, later, to use SilcDList.
7172 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7173 and use TRQ internally).
7175 Also fixed some annoying warning messages that the original TRQ
7176 code generated. Also minor changes to TRQ's Makefile.in.
7178 * Added support for querying by Client ID to both WHOIS and
7179 IDENTIFY commands into server, as required by the protocol.
7181 * Removed method function pointers from SilcBuffer structure. They
7182 weren't used to anything and just increased the context size for
7183 no good reason. This change also made silc_buffer_alloc and
7184 silc_buffer_free functions inline functions.
7186 * Disabled command flooding detection support until it's fixed so
7187 that it accepts commands in but does not execute them more than once
7190 * Added silc_net_localhost(), to return local hostname, into
7191 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7192 that must be initialized before calling silc_client_init.
7194 * Added new function: silc_server_send_notify_on_channels to send
7195 notify messages to all channels client has joined. It is assured
7196 that the message is sent only once per client.
7198 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7199 lib/silcutil/silcutil.[ch] as silc_format function. The new
7200 function is generic and is used by server as well, not only by
7201 the logging routines.
7203 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7204 the provided version string was not acceptable. Added new function:
7205 silc_ske_check_version into lib/silcske/silcske.h. The function
7206 must be implemented by the application (client or server) and it
7207 does not reside in the SKE library. The function checks the version
7208 string remote end sent.
7210 * Added back pointers (to opaque context and to SilcSocketConnection)
7211 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7213 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7214 duplicate packet context structure.
7216 * Changed `notify' client operation to send same arguments as client
7217 receives from server except for ID's. ID's are mapped to correct
7218 ID entry and that is returned. Also, if channel entry is not sent
7219 by server but the notify is for channel the channel entry is sent
7220 to application (otherwise application doesn't know that it is for
7221 channel (library gets it from packet's Destination ID)).
7223 * Added silc_client_remove_from_channels into client library to
7224 remove a client from all channels it has joined to. Used when
7225 received SIGNOFF notify from server. Added also new function
7226 silc_client_replace_from_channels to replace old ID entry with
7227 new ID entry on all channels. Used when received NICK_CHANGE
7230 * Fixed ID Cache list handling in silc_idlist_get_client in
7231 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7232 to get (or query) client by ID.
7234 * Updated TODO list.
7236 * Added connection authentication status message defined by the
7237 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7238 support for these into the code in client and server side.
7240 * Added generic function silc_client_send_command to send any command
7241 with variable argument list. Application should use this function
7242 to send commands if the command functions provided by the library
7243 does not suite for the application's user interface needs.
7245 * Added new `failure' client operation. Application is notified about
7246 received failure packet if client is executing a protocol. In this
7247 case the protocol's execution has failed.
7249 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7250 is required by the protocol.
7252 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7253 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7256 * Added status flag to SilcSKE object to indicate realtime status
7257 of the SKE protocol.
7259 * Application receives now exactly same command reply arguments as
7260 the library receives from server. However, if ID is received the
7261 corresponding ID entry is returned to the application (eg. Client
7262 ID is mapped to correct SilcClientEntry entry and that is returned).
7263 Changed command_reply client operation due to this change.
7265 * Changed all ID's in commands and in command replys as ID Payloads.
7266 Change affected both client and server side codes.
7268 All ID's sent in SILC network (with execption of ID's in SILC
7269 Packet header) are sent in ID Payload to support variable length
7272 * Server now notifies nick changes and notifies all clients on
7273 the channels about the new nickname (about the new Client ID,
7276 * Implemented CMODE command to change channel modes. Supports all
7277 channel modes defined by the protocol specs except ban and invite
7278 lists. (Also, private channel key mode is supported but support for
7279 setting private channel key in client is missing, thus, this mode
7280 has no effect on client side (except that server requires that the
7281 client uses private channel key and normal channel traffic does not
7284 Also, invite mode works per se, but INVITE command does not work
7285 yet correctly, so you can set channel as invite only channel but
7286 inviting clients to the channel does not work (it is yet to be
7287 thought what's the best way to do it).
7289 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7290 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7291 Implemented CUMODE command to change user's mode on the channel.
7292 Supports all modes defined by the protocol specs.
7294 * Added NAMES command reply to return users modes on the channel.
7296 * Removed unnecessary and slow ciphers from lib/silccrypt.
7298 * Set SO_KEEPALIVE option to connection sockets by default.
7300 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7302 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7303 redefined the Notify Payload into protocol specs.
7305 * Added silc_id_payload_parse_id to get ID directly from raw
7308 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7310 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7311 accept searching by Client ID as well.
7313 * Added support for LEAVE and SIGNOFF notify types in client library.
7315 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7316 to parse ID Payload from raw data.
7318 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7320 * Added flags parameter into silc_ske_assemble_security_properties
7321 function in lib/silcske/silcske.[ch].
7323 * Changed notify client operation to fit better for notify messages
7324 sent by server. The notify payload received from server is now
7325 passed to the application (after parsing it to SilcNotifyPayload).
7326 It is application's responsibility to retrieve the arguments
7327 from the payload and show the message the way it wants. The message
7328 sent by server is implementation specific.
7330 * Changed public keys to comply with the protocol specification.
7331 Old public keys are not supported anymore and are not compatible.
7333 * Removed nickname from Channel Payload as the latest draft removed
7334 it. The client must resolve the nickname from the NAMES command
7335 reply received when it joined the channel.
7337 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7339 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7341 * Fixed some errors in protocol specification drafts.
7343 * Created lib/silccore/silcnotify.c to implement Notify Payload
7344 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7345 generic payloads described by protocol specifications. The file
7346 includes implementations for ID Payload and Argument Payload.
7348 * Changed Command Payload implementation to use the new Argument
7349 Payload. Changed command_xxxx_payload to command_payload_xxxx
7350 to comply with SILC coding conventions.
7352 * Added suppport for Argument Payload handling in Notify Payload
7353 implementation as protocol requires it. Added the new support
7354 into server and client lib as well.
7356 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7358 * Added support for multiple nicknames on same channel. [n] is
7359 added locally to the nickname if there are more than one same
7360 nicknames on the channel.
7362 * Server now sends all nicknames that matched WHOIS request.
7363 Client also shows the list received from server.
7365 * Added TOPIC command to client side. User can now set and show
7366 current topic on channel.
7368 * Added MOTD command to client and server. Also, server sends the
7369 motd when client connects to the server.
7371 * Changed version strings to comply ISO 8601.
7373 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7375 * Fixed protocol error handling in client library. It should now
7376 cope even if the SKE fails for some reason.
7378 * Made new protocol specification drafts for submitting to IETF.
7380 * Implemented TOPIC command to server in silcd/command.c.
7382 * Added two new notify types into lib/silccore/silcnotify.h:
7383 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7384 notify nickname change and topic setting/change on a channel.
7386 * API change of command_reply operation in client library. The
7387 application gets now the status type received from server as well.
7389 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7391 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7393 * Cras fixed and optimized the packet handling even further and
7394 it should work now. Minor change to the prototype of function
7395 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7397 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7399 * Added new function into lib/silcutil/silcschedule.[ch]:
7400 silc_schedule_with_fd to select() a specified fd. The function
7401 returns after timeout expires or data arrives or goes. The
7402 function is used by packet routines to wait that all data is
7403 received from network.
7405 * Fixed data reading from network in lib/silccore/silcpacket.c.
7406 The code now assures that all data is read from the fd and then
7407 continues packet processing. This was a bug fix since the code
7408 used to drop some data in some circumstances.
7410 * Added new function into lib/silcclient/client.[ch]:
7411 silc_client_start_key_exchange to start key exchange after
7412 connection has been established to server. The code internally
7413 now uses this funtion but its main purpose was to provide it
7414 for applications that perform their own connecting. After
7415 application has created a connection it merely calls this
7416 function to start the key exchange between client and server.
7417 The library takes care of everything else after that.
7419 Updated also lib/silcclient/README to explain the usage of
7422 * Do not send to application information that connection has
7423 been established. Application gets notified it by connect
7426 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7428 * Applied cras's patch to add silc_schedule_one function. The
7429 function runs scheduler once and returns.
7431 * Fixed the scheduler after cras messed it up. The timeout
7432 handling works now as it's supposed to work.
7434 * Added into lib/silccore/ silcnotify.h to include notify
7435 message types support. Changed silc_server_send_notify*
7436 functions, in server.[ch], to support those new notify types.
7437 Added the support for the notify types into client library,
7438 as well. Added new notify client operation into ops.h in
7441 * Changed silc_server_packet_send_to_channel to send normal
7442 packets instead of just channel message packets. The function
7443 is now used to send the notify packets to channels. It is not
7444 used to send channel message packets anymore, as server never
7447 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7448 va_arg()s as it seems to require it nowadays. I guess, if SILC
7449 is compiled with older va_arg() the new code should work anyway.
7451 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7453 * Splitted core library. Core library (lib/silccore) includes
7454 now only SILC protocol specific core (and common) components.
7455 Created new utility library (lib/silcutil) that includes more
7456 generic purpose stuff. The stuff for util library was taken
7457 from the old core library. This was minor and easy split.
7459 * Created SILC Client Library (lib/silcclient) that includes
7460 implementation of the SILC client without user interface. This
7461 was major move from silc/ directory. The code has been changed
7462 so that it is transparent towards the user interface. The
7463 silc/ directory includes now the same user interface as before
7464 and it uses the new client library. Read lib/silcclient/README.
7465 Basicly, the client library performs everything else related
7466 to SILC except user interface handling. Also, configuration
7467 files are considered to be part of user interface and library
7468 does not handle them.
7470 This change also changed a lot of structures, function naming etc.
7471 Most important change was that SilcClientWindow object was
7472 renamed to SilcClientConnection in the client library. Created
7473 also new file lib/silcclient/ops.h. Also added new files
7474 silc/local_command.[ch] and silc/client_ops.[ch].
7476 All these changes were made to make it easier for user interface
7477 designers to create what ever user interface for the SILC client
7480 It is also expected that the server will be moved to lib
7481 directory as well and SILC Server Library will be created;
7482 sometimes in the future.
7484 * Removed Local commands from lib/silccore/silccommand.h as
7485 they are application specific and new client library does not
7486 handle any of those anymore.
7488 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7489 old client implementation in silc/.
7491 * Added support for callback functions in SILC_LOG_* macros.
7492 Application can now set its own callbacks that will be called
7493 instead of using the default functions that will always print
7494 the debug messages to stderr (or stdout). Also, debugging can
7495 now be disabled by setting silc_debug to FALSE and re-enabled by
7496 setting it to TRUE. Note, that logging will still work even
7497 if debugging is disabled.
7499 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7500 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7501 silc_log_reset_debug_callbacks.
7503 * To enable debugging in silc client one must give now -d
7504 option on command line.
7506 * Changed silc_schedule_init to automatically allocate task queues
7507 if they are not allocated before calling it.
7509 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7511 * Added GMP 3.1 into math library.
7513 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7515 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7516 a channel in SILC network. The packet is used by servers and
7517 routers to notify other routers that user has left a channel.
7518 This little feature was missing until now. Added the feature
7519 to protocol specification as well.
7521 Added functions: silc_server_send_remove_channel_user and
7522 silc_server_remove_channel_user into server.[ch].
7524 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7525 lib/silccore/silcpacket.h. However, they are not implemented
7528 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7530 * Fixed joining to a channel and sending channel messages
7531 between server and router. The channel message sending should
7532 now work inside a cell.
7534 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7536 * Fixed the private message sending between server and router.
7537 The private message sending should now work inside a cell.
7539 * Added silc_server_replace_id into server.[ch] to replace
7540 existing ID in the SILC network.
7542 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7543 and silc_idlist_replace_server_id into idlist.[ch] in server.
7545 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7547 * Fixed the server to server connections. Server can again now
7548 connect to router. Router to router connections probably does
7551 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7553 * Added dynamic protocol registering support. Now protocols can
7554 registered and unregistered on the fly. Patch by cras.
7556 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7558 * Added lib/contrib directory to hold routines that some platforms
7559 don't have but are needed by SILC.
7561 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7562 into lin/contrib to provide getopt() and getopt_long() for
7563 those who don't have it.
7565 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7567 * Added AWAY command to client. When away message is set and
7568 client receives a private message packet the client automatically
7569 replies to the sender with the away message.
7571 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7572 bug seemed to be the cause of recent problems when compiling
7575 * Added version detection support to SKE protocol specification
7576 and added the new changes to the SKE implementation as well.
7577 There were other minor changes in the SKE protocol as well.
7579 Many changes in lib/silcske/silcske.[ch] and in
7580 lib/silcske/payload.[ch].
7582 * Added ^U functionality, clear input line. Patch from cras.
7584 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7586 * Mainly small bugfixes on core library. Fixed some debugging
7587 logging and buffer overflow in silclog.c.
7589 * Updated config.sub and config.guess on the distribution tree.
7591 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7593 * Added command lagging support in server. Client may execute
7594 commands now only once in two seconds.
7596 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7598 * Optimized packet reception. MAC computation and checking is now
7599 also more optimized. A lot previously duplicated code is now
7600 used as generic by both client and server.
7602 * Fixed key pair generation in clientutil.c
7604 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7606 * Added into lib/silccore/silcbufutil.[ch] new function;
7607 silc_buffer_realloc.
7609 * Moved generic packet sending/encryption functions to
7610 lib/silccore/silcpacket.[ch] from client and server. Some
7611 rewriting of the functions.
7613 * Moved all generic packet reception/decryption functions to
7614 lib/silccore/silcpacket.[ch] from client and server. The
7615 packet processing is now much cleaner in both client and server.
7616 These were major changes in both client and server.
7618 * Created many common functions in server to do packet sending.
7619 Previously code were duplicated a lot, this has been removed
7622 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7624 * Rewrote major parts of the ID cache system. Don't know
7625 whether it is better now or not but at least the API is more
7628 * Major rewrite on ID cache stuff on client because of the ID
7629 cache API changes. Added idlist.c to client.
7631 * Also major rewrite on ID cache stuff on server as well.
7632 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7633 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7634 in hand, instead they are all put into the ID cache system now.
7635 All server_idlist_* routines uses ID cache now instead of
7636 traversing its own lists (those lists does not exist anymore).
7637 SilcIDList though still exists. Also, SilcXXXEntry's are
7640 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7642 * Finally made the SKE implementation compliant to the protocol
7643 specification. All mp integers are now binary encoded as
7644 opposed being HEX encoded.
7646 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7649 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7650 functions: silc_[encode/decode]_pem. Also added function
7651 silc_encode_pem_file to PEM encode with newlines ('\n') for
7654 * SILC public keys are now encoded either PEM or binary. Same
7655 option is for private keys as well. By default private keys
7656 are binary encoded and public keys PEM encoded. Silly HEX
7657 encoding were removed.
7659 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7660 function to create fingerprints.
7662 * Fixed a bug in SHA1; does not change the original data anymore.
7664 * Partly implemented INFO command on client and server side.
7665 Fixed CLEAR command. Changes to SERVER command; show current
7666 server(s) when giving command without arguments. Added
7667 VERSION command to client.
7669 * Added check to server that unregistered connections cannot
7670 execute commands (unless it is specificly allowed).
7672 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7674 * Fixed screen refresh.
7676 * Fixed channel joining bug from client. On some circumstances
7677 client tried to join to a channel it had already joined.
7679 * Added public key verification process into client's protocol.c.
7680 The client now verifies the public key from user and saves
7681 it into ~./silc/serverkeys/ directory.
7683 Added into: clientutil.[ch]: silc_client_verify_server_key.
7685 * Changed SKE protocol's silc_ske_initiator_finish function
7686 to accept callback function that verifies the received public
7687 key. Removed old silc_ske_verify_public_key function.
7689 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7691 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7692 silc_pkcs_private_key[_data]_set.
7694 * Made the password and public authentication more cleaner in
7695 server's protocol.c.
7697 * Removed historic and obsolete protocol `channel_auth' from
7698 both client and server.
7700 * Removed wrong way of sending command status messages from
7701 server to client in server's command.c. The old way violated
7702 protocol specification.
7704 Changes to silccore/silccommand.[ch]: removed
7705 silc_command_encode_status_payload -> not needed anymore,
7706 changed silc_command_encode_payload_va to accept extra
7707 argument on variable argument list. The argument type must
7708 now be provided to the function. Also, added new function:
7709 silc_command_encode_reply_payload_va which is same as
7710 normal command_encode_payload_va except command status type
7711 is provided as extra argument.
7713 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7715 * Added ~./silc directory handling. The directory includes the
7716 public and private keys for the client.
7718 Added silc_client_check_silc_dir, silc_client_create_identifier
7719 and silc_client_load_keys.
7721 * Implemented SILC protocol compliant public key. Added public
7722 and private key saving to and loading from files.
7724 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7725 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7726 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7727 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7728 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7730 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7731 silc_pkcs_load_[public/private]_key.
7733 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7735 * Added silc_server_get_route (route.[ch]) to get connection
7736 data for the fastest route for given ID.
7738 * Implemented INVITE command on client and server. The command
7739 were re-defined in the SILC Protocol Specification and the
7740 implementation now complies with the specification.
7742 * Implemented PING command on client and server.
7744 * Implemented NAMES command on client and server. The server side
7745 supports currently only normal server not router server yet.
7746 Some changes to NAMES definition in SILC protocol specification.
7748 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7750 * Implemented LEAVE command on client and server.
7752 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7753 again. This change was made to the protocol as well. Server
7754 should not violate the protocol specification anymore.
7756 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7758 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7759 was tested. SOCKS4 was not but should work anyway.
