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

535 now possible to load it as module. Affected files
536 irssi/src/silc/core/silc-core.c,
537 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
539 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
541 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
544 * Fixed the silcdoc document generator to correct generate

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

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

650 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
652 * Added new configuration options and blocks:
653 keepalive_secs, reconnect_count, reconnect_interval,
654 reconnect_interval_max, reconnect_keep_trying and
655 require_reverser_lookup. Added ConnectionParam block, and
656 implemented the connection parameters when connecting as
657 initiator and when accepting connections as responder.

660 whether given configuration value has been given already.
662 Affected files silcd/serverconfig.[c], server.[c].
664 * Splitted the doc/example_silcd.conf.in. Separated the crypto
665 algorithm parts and created new file silcalgs.conf, that
666 is now included from the example_silcd.conf.in.
668 * Optimized the silc_server_connect_to_router_second to take
669 the connection configuration object from the SilcServerConnection
670 object instead of finding it during the connecting phase.
671 Added the configuration object to SilcServerConnection struct.
672 Affected files silcd/server_internal.h, server.c.
674 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

688 * Unified the serverconfig.[ch]'s helper function interface.
689 Affected file silcd/serverconfig.[ch].
691 * Removed doc/example_silc.conf.in since it is redundant.
692 The make install will now install irssi/silc.conf file.
694 * Added new Passphrase and Publickey authentication methods to
695 config file, allowing both public key and passphrase based
696 authentication to be set at the same time.
698 Added `prefer_passphrase_auth' setting in config file which
699 can be used to set to prefer passwd auth if both passwd and
700 public key is set. If not set, public key is preferred.
701 This has effect only when being initiator (responder will try
704 Added support for authentication with passphrase and public key
705 at the same time. The passphrase is tried first always since
706 it is faster to check.
708 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
710 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

749 correct client. Affected file lib/silcclient/client_notify.c.
751 * Make silc_rng_alloc fail if it cannot allocate the sha1
752 hash algorithm. Affected file lib/silccrypt/silcrng.c.
754 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
756 * Fixed the file transfer's key agreement payload to include
757 zero port also if the hostname is NULL because it could not
760 Call file transfer monitor callback now also if error occurs
761 during key agreement protocol.
763 Changed the silc_client_file_send interface to return the
764 SilcClientFileError instead of session id. The session ID
765 is returned into pointer provided as argument.
767 Check that the file exists locally before sending the
768 file transfer request at all.
770 Affected file lib/silcclient/client_ftp.c, silcapi.h.

781 SILC_LOG_WARNING to give out Warning and not Error. Affected
782 file lib/silcutil/silclog.c.
784 * Fixed the channel message payload decryption in the function
785 silc_channel_message_payload_decrypt to not modify the original
786 buffer before it is verified that the message decrypted
787 correctly. Otherwise, next time it is called with correct
788 channel key it won't encrypt since the payload is corrupted.
789 Affected file lib/silccore/silcchannel.c.
791 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

827 * Added function silc_client_add_channel,
828 silc_client_replace_channel_id, and removed functions
829 silc_client_new_channel_id and silc_idlist_get_channel_by_id
832 * Added cross reference of the joined channels to the
833 SilcClientEntry, and changed the SilcChannelEntry's
834 users list to SilcHashTable. The affected files are
835 lib/silcclient/idlist.[ch].
837 * Fixed a bug in hash table tarversing. While the hash table
838 is traversed with SilcHashTableList the table must not be
839 rehashed. It is now guaranteed that auto rehashable tables
840 are not rehashed while tarversing the list. Also defined that
841 silc_hash_table_rehash must not be called while tarversing
842 the table. Added function silc_hash_table_list_reset that must
843 be called after the tarversing is over. The affected files are
844 lib/silcutil/silchashtable.[ch].
846 * Changed all hash table traversing to call the new
847 silc_hash_table_list_reset in server and in client library.
849 * Added function silc_client_on_channel to return the
850 SilcChannelUser entry if the specified client entry is joined
851 on the specified channel. This is exported to application as
852 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
854 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
856 * Fixed founder regaining problem with JOIN command on normal
857 server. The notify for mode change must be sent always and
858 not only if !cmd->pending. Affected file silcd/command.c.
860 * Fixed the WHOWAS command's reply sending to support the
861 lists correctly. Affected file silcd/command.c.
863 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
865 * When sending JOIN command to router for processing the
866 sender's old command identifier was not saved back to the
867 sender's command context, fixed now. The affected file is
870 * Create the key in JOIN command of the router did not return
871 the channel key, added check for this. Affected file is
874 * Fixed a channel ID update bug in JOIN command reply. Do
875 not directly upgrade the ID but call the function
876 silc_idlist_replace_channel_id if the ID was changed.
877 Affected file silcd/command_reply.c.
879 * Fixed memory leaks from command calling if it would fail.
880 Affected file silcd/command.c.
882 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

943 * Added server & router operator statistics updating. Affected
944 file silcd/packet_receive.c and silcd/command.c.
946 * Fixed the SERVER_SIGNOFF notify handling on normal server
947 not to save the history information for clients. Same was
948 fixed earlier in remove_clients_by_server function, but not
949 here. Affected file silcd/packet_receive.c.
951 * Raised the default connection-retry count from 4 to 7 in
952 server. Affected file silcd/server.h.
954 * Cancel any possible reconnect timeouts when we start the
955 key exchange. Affected file silcd/server.c.
957 * Do not reconnect on connection failure when SCONNECT was
958 given. Affected files silcd/server.[ch].

962 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
964 * Fixed the NICK command to always give the unformatted
965 nickname to the one giving the NICK command. If unformatted
966 nickname is cached already it will be formatted and the
967 local entry will always get the unformatted nickname.
968 Affected file lib/silcclient/idlist.c.
970 * Fixed some double frees from client library commands.
971 Affected file is lib/silcclient/command.c.
973 * Fixed CUMODE command in server to assure that no one can
974 change founder's mode than the founder itself, there was a
975 little bug. Affected file silcd/command.c.
977 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
979 * Removed the SilcClientCommandDestructor from the client
980 libary, it is not needed anymore. Affected files are
981 lib/silcclient/silcapi.h, command[_reply].[ch],
982 client_notify, idlist.c.
984 * Fixed GETKEY command to first resolve client, and then
985 resolve the server only if the client was not found, instead
986 of resolving both at the same time. Affected file is
987 lib/silcclient/command.c.
989 * Added silc_client_start_key_exchange_cb and lookup the
990 remote hostname and IP address before starting the key
991 exchange with server. The affected file is
992 lib/silcclient/client.c.
994 * The server's public key is now saved using the IP address
995 of the server and not the servername for the filename.
996 The hostname public key filename is checked as an fall back
997 method if the IP address based filename is not found.
999 Fixed the GETKEY command to save the fetched server key
1000 in correct filename.
1002 Print the remote server's hostname now when new key is
1003 received during connection process. Affected file is
1004 irssi/src/silc/core/client_ops.c.
1006 * Return always our own public key to the client if it asks
1007 for it with GETKEY command. Affected file silcd/command.c.
1009 * Removed the use_auto_addr variable from default config
1010 file since it was in wrong section. Affected file is
1013 * Fixed TOPIC_CHANGE notification to not route it when it
1014 was sent using silc_server_send_notify_to_channel function.
1015 Affected file silcd/command.c.
1017 * Fixed silc_server_send_notify_kicked to send the kicker's
1018 Client ID also, it was missing. Affected files are
1019 silcd/command.c, silcd/packet_send.[ch].
1021 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1023 * Do not save client history information in SERVER_SIGNOFF.
1024 Fixes the bug in normal server that it does not detect
1025 the client becoming valid after the server becomes back
1026 online. Affected file silcd/server_util.c.
1028 * Added `sock_error' field into the SilcSocketConnection
1029 context. When error occurs during socket operation (read
1030 or write) the error is saved. Added also new function
1031 silc_socket_get_error to return human readable socket error
1032 message. Affected files are lib/silcutil/silcsockconn.[ch],
1033 lib/silcutil/unix/silcunixsockconn.c, and
1034 lib/silcutil/win32/silcwin32sockconn.c.
1036 * The server now prints the socket error message in the
1037 signoff for client. Affected file silcd/server.c.
1039 * Fixed the `created' channel information sending from router
1040 to server in JOIN command. Checks now whether the channel
1041 really was created or not and set it according that.
1043 Fixed the JOIN command to use the client entry's current
1044 ID during the joining procedure instead of the one it sent
1045 in the command (it is checked though), since it can change
1046 between the packet processing and command processing, and
1047 would just case unnecessary pain in the client end. Affected
1048 file silcd/command.c.
1050 * Fixed a channel key payload sending to use correct channel
1051 ID when the server was forced to change the channel's ID by
1052 router. Router sent the key payload with the old Channel ID.
1053 Affected file silcd/packet_receive.c.
1055 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1057 * Call silc_server_save_channel_key only if the key payload
1058 was provided in the JOIN command's command reply. Affected
1059 file silcd/command_reply.c.
1061 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1063 * Fixed silc_mp_sizeinbase to return the value correctly with
1064 MPI. Affected file lib/silcmath/mp_mpi.c.
1066 * Fixed the stop_server signal to correctly stop the scheduler
1067 and gracefully stop the server when SIGTERM or SIGINT signals

1070 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1072 * Simple handling of TERM and HUP signals. Also added some log
1073 flushing call around. Affected file is
1076 * Fixed small bugs in silclog.c. Now buffering output will take
1077 effect after 10 seconds since startup: This will ensure that
1078 no important startup messages are lost. Also output redirection
1079 will preserve original format ([Date] [Type] message).
1080 Affected file is lib/silcutil/silclog.c.
1082 * Added two options to the config file, in the logging section:
1083 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1084 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1086 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1088 * Do not print the warning about log files not being initialized
1089 more than once to avoid excess logging. Affected file is
1090 lib/silcutil/silclog.c.
1092 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1093 the SIM copying in make install in Makefile.am.pre.
1095 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1097 * Rewritten silclog APIs. Globally interesting changes follows:
1098 silc_log_set_files() changed to silc_log_set_file().
1099 silc_log_set_callbacks() changed to silc_log_set_callback().
1100 ROBOdoc documented silclog header file.
1101 SilcLogCb now returns bool to wether inihibit the default
1102 handler or not (to keep the old behaviour return always TRUE).
1103 The new APIs should also fix the problem of the
1104 silcd_error.log file that was written in the current directory.
1107 Log files streams will remain opened after silc_log_set_file()
1108 call, means less CPU usage notably on high traffic servers.
1109 File streams are now full buffered, and flushed to the disk
1110 every 5 minutes, lesses HD activity and CPU usage.
1111 Messages can be redirected, allowing admins to configure
1112 one single logfile for all server messages.
1113 the silc_log_quick global variable to activate fast-logging.
1114 Affected files lib/silcutil/silclog.[ch]
1116 * Changed some code to conform new silclog APIs. Affected
1117 files are doc/example_silcd.conf.in, silcd/server.c
1118 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1121 * Fixed a memory leak that could occur in some situations.
1122 Affected file silcd/serverconfig.c.
1124 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1126 * Added the silc_client_del_client to remove the client from
1127 all channels as well. Affected file lib/silcclient/idlist.c.
1129 * Fixed the client library to correctly remove the client
1130 from all channels when the client entry is being destroyed.
1131 Affected file lib/silcclient/client_notify.c, command.c.
1133 * Added auto-nicking support to the client library. If the
1134 applicatio now sets client->nickname it will be sent to the
1135 server after connecting by the library. This way for example
1136 SILCNICK (or IRCNICK) environment variables will have effect
1137 and always change the nickname automatically to whatever
1138 it is wanted. Affected file lib/silcclient/client.[ch].
1140 * Renamed silc_server_command_bad_chars to the
1141 silc_server_name_bad_chars and moved it to the
1142 silcd/server_util.[ch]. Added also new function
1143 silc_server_name_modify_bad to return nickname that
1144 includes bad characters as new nickname without those
1145 bad characters. This check and modify is now used in
1146 silc_server_new_client when the username is initially set
1147 as nickname, so it must be checked to be valid nickname.
1148 Affected file silcd/packet_receive.c.
1150 * The nickname length is now taken from the packet for real
1151 and not trusted to strlen() since it clearly can return
1152 wrong length for nickname including bad characters. This
1153 also applies to channel names. Affected file silcd/command.c.
1155 * Removed the lib/silcsilm/modules directory. Modules are now
1156 compiled into the lib/silcsim. Fixed the copying of the
1157 modules to follow symbolic links in Makefile.am.pre.
1159 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1161 * Fixed silc_string_regexify list creation. Fixes bugs with
1162 BAN and INVITE commands in server. The affected file is
1163 lib/silcutil/unix/silcunixutil.c.
1165 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1167 * Removed the command destructor entirely from the server's
1168 command and command reply routines. It is not needed, and
1169 its usage was buggy and caused crashes. Affected files are
1170 silcd/command[_reply].[ch].
1172 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1174 * Cancel protocol and NULL sock->protocol if timeout
1175 occurred during protocol. Affected file silcd/server.c.
1177 * Cancel protocol timeouts always before calling the final
1178 callback, to assure that after final callback is called
1179 no other state will be called for the protocol anymore.
1180 Affected file silcd/protocol.c.
1182 * Print error log if incoming connection configuration could
1183 not be found. Affected file silcd/server.c.
1185 * Fixed JOIN command to correctly save the founder mode
1186 to the client on normal SILC server, when the channel
1187 was created by the router. Affected file silcd/command.c.
1189 * Fixed LIST command (hopefully) to send correct reply
1190 packets. Affected file silcd/command.c.
1192 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1194 * The silc_packet_receive_process now returns FALSE if the
1195 read data was invalid packet, and TRUE if it was ok.
1197 The server now checks that if unauthenticated connection
1198 sends data and its processing fails the server will close
1199 the connection since it could be a malicious flooder.
1201 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1203 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1205 * Make sure the warning about error opening a log file is
1206 printed only once and not everytime it fails (produces
1207 too much useless log). Affected file lib/silcutil/silclog.c.
1209 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1211 * Made the silc_server_daemonise() function more readable.
1212 Affected file silcd/server.c.
1214 * Pid file is now optional, the user may comment it out from
1215 the config file. Removed define SILC_SERVER_PID_FILE, we
1216 don't need a default any longer. Affected file
1217 configure.in.pre, lib/Makefile.am.pre.
1219 * Make some use of the pid file. The server now dies at startup
1220 if it detects a valid pid file on his path. The server would
1221 die anyway in this circumstance, because of the bind() failure.
1222 Affected file silcd/silcd.c.
1224 * No longer compiling lib/dotconf.
1226 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1228 * Fixed JOIN command parsing not to crash. Affected file
1229 lib/silcclient/command.c.
1231 * Fied the NICK_CHANGE notify to add the new client entry
1232 even it is resolved. This removes an <[unknown]> nick
1233 thingy bug in the client. Affected file is
1234 lib/silcclient/client_notify.c.
1236 * Do not try to allocate 0 bytes (efence does not like it)
1237 in lib/silccore/silccomand.c when encoding payload.
1239 * Do not take IRCNICK as nickname in Irssi SILC client since
1240 it is not possible to set nickname before hand connecting
1241 the server (TODO has an entry about adding auto-nicking
1244 * Changed the silc_server_command_pending to check whether
1245 there already exists an pending entry with the specified
1246 command, command identifier and pending callback. This is
1247 to fix IDENTIFY and WHOIS related crashes that may register
1248 multiple pending commands with same identifier. Affected
1249 file silcd/command.c.
1251 * Fixed the server to reconnect to the router even if it
1252 was already reconnecting and EOF was received. This to
1253 fix a possibility that the server wouldn't ever try to
1254 auto-reconnect to the router. Affected file silcd/server.c.
1256 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1258 * Fixed the server's password authentication to use the
1259 length of the locally saved password, and not the one
1260 sent in the packet. Affected file silcd/protocol.c.
1262 * Fixed same password authentication problem in the
1263 Authentication Payload handling routines in
1264 lib/silccore/silcauth.c.
1266 * Yet another password authentication problem fixed with
1267 channel password handling in silcd/command.c.
1269 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1271 * If first character of string in silc_parse_userfqdn is '@'
1272 then do not parse it. Affected file is
1273 lib/silcutil/silcutil.c.
1275 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1277 * Fixed minor bug in IDENTIFY command reply sending, which
1278 caused various weird problems during JOIN when it was
1279 resolving names for users. Affected file silcd/command.c.
1281 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1283 * Fixed the IDENTIFY command reply sending to chech better valid
1284 clients. It was possible to send incomplete list of replies.
1285 Affected file silcd/command.c.
1287 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1289 * Added silc_client_command[s]_[un]register functions now to
1290 dynamically register the commands in client library. Removed
1291 the static table of commands. This allows the client library
1292 to call commands without causing the application to know about
1293 what commands library has called.
1295 Removed the INFO command reply kludge to detect when the command
1296 was called by library. Now library use its own command reply
1297 function for INFO command.
1299 Added function silc_client_command_call to call a command.
1300 Application can use it to call command, not access the structure
1303 Now all commands that are sent by the client library (not
1304 explicitly sent by application) use own command reply functions.
1306 Affected files around lib/silcclient/ and in
1307 irssi/src/silc/core/.
1309 * Fixed the WHOIS command reply sending to chech better valid
1310 clients. It was possible to send incomplete list of replies.
1312 Fixed the WHOIS and IDENTIFY to send the request to router
1313 if normal server did not do it and did not find any results.
1315 Affected file silcd/command.c.
1317 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Moved the internal data from SilcClient context into its
1320 own file, not accesible to application. Affected files
1321 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1322 and other files in client library.
1324 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1326 * Added doc/examples installation target in Makefile.am.pre.
1329 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1331 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1332 commands the found client entry will be removed from the
1333 cache, after notifying application about the error. Affected
1334 file lib/silcclient/command_reply.c.
1336 * Changed the /MSG to check for exact nickname user gave, and
1337 not let `nick' match `nick@host' if it is only one found. Now,
1338 user must type the exact nickname (like nick@host2) even if
1339 there are no more than one same nicks found. This is to avoid
1340 a possibility of sending nickname to wrong nickname since
1341 `nick' could match `nick@host'. Affected file is
1342 irssi/src/core/silc-servers.c.
1344 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1346 * Do not print "you are now server operator" or similar when
1347 giving /away command. Affected files are
1348 irssi/src/silc/core/client_ops.c, silc-servers.h.
1350 * Made the silc_server_command_pending_error_check to send
1351 the same command reply payload it received back to the
1352 original sender of the command. This way all arguments
1353 that was received by the server will be received by the
1354 client too. Affected file silcd/command.c.
1356 * Added the silc_idcache_add to return the created cache entry
1357 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1359 * Add global clients to expire if they are not on any channel.
1360 This is because normal server will never know if they signoff
1361 if they are not on any channel. The cache expiry will take
1362 case of these entries. This is done by normal servers only.
1363 The affected files are silcd/command_reply.c,
1364 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1366 * If server receives invalid ID notification for WHOIS or
1367 IDENTIFY and the ID exists in the lists, it is removed.
1368 Affected file silcd/command_reply.c.
1370 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1371 in client then client entry that it matches is searched and
1372 the nickname is printed on the screen for user. Affected
1373 file irssi/src/silc/core/client_ops.c.
1375 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1377 * Use cache entry expire time in the LIST command reply to
1378 purge old entries from the cache after the LIST command
1379 reply has been received. This way we don't have non-existent
1380 entries in the cache for too long. Affected file is
1381 silcd/command_reply.c.
1383 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1385 * If we are normal server, and we've not resolved client info
1386 in WHOIS or IDENTIFY from router, and it is global client,
1387 we'll check whether it is on some channel. If it is not
1388 then we cannot be sure about its validity and will resolve it
1389 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1390 file silcd/command.c.
1392 * Search channel by name (if possible) rather than by ID
1393 in IDENTIFY command's command reply. Affected file is
1394 silcd/command_reply.c.
1396 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1398 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1399 Updated specs and implemented it. Affected file silcd/command.c,
1400 silcd/packet_send.c and silcd/packet_receive.c.
1402 * Implemented the <founder auth> payload handling in the JOIN
1403 command. If provided all conditions for channel joining
1404 except requirement to provide correct passphrase can be
1405 overrided by the channel founder. Updated the protocol specs.
1406 Affected file silcd/command.c.
1408 Added support for founder auth in JOIN command in client
1409 library. Fixed the parsing of the JOIN command now to support
1410 all options as they should be. The affected file is
1411 lib/silcclient/command.c.
1413 * Optimized the WHOIS and IDENTIFY commands to send the request
1414 to router only if it includes nicknames or other names. If
1415 they include only IDs then check the local cache first before
1416 routing. Affected file is silcd/command.c.
1418 * Added channels topic announcements. Affected file is
1419 silcd/packet_receive.c and silcd/server.c.
1421 * Fixed the silc_server_send_notify_topic_set to really destine
1422 the packet to channel. Affected file silcd/packet_send.c.
1424 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1425 library. Affected file lib/silcclient/client_notify.c.
1427 * Added UMODE announcements. Affected file silcd/server.c.
1429 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1431 * Memory leak fixes in:
1433 lib/silcutil/silcsockconn.c
1434 lib/silcske/silcske.c
1435 lib/silcske/groups.c
1437 lib/silccrypt/silcpkcs.c
1438 lib/silccore/silccommand.c
1439 lib/silccore/silcidcache.c
1444 * ROBOdoc documented the lib/silcske/groups.h file and a
1445 bit changed the interface for better.
1447 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1449 * Update the client entry context in the ID cache after
1450 nick change. Affected file lib/silcclient/command.c.
1451 Fixes the CUMODE command when regaining founder privileges,
1452 and a little WHOIS problem.
1454 * Fixed silc_net_gethostbyname to correctly call the
1455 inet_ntop. Affected file lib/silcutil/silcnet.c.
1457 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1459 * Added IPv6 support checking to the configure.in.pre, added
1460 also --enable-ipv6 option to override the check. Affected
1461 file configure.in.pre.
1463 * The silc_thread_create now calls the start function
1464 directly if threads support is not compiled in. Removes
1465 ugly #ifdef's from generic code. Affected files are
1466 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1468 * Added silc_net_gethostby[name/addr]_async to asynchronously
1469 resolve. Affected files are lib/silcutil/silcnet.[ch].
1471 * Added support for rendering IPv6 based server, client and
1472 channel IDs. Affected file lib/silcutil/silcutil.c.
1474 * Added support for creating IPv6 based server IDs. Affected
1475 file is silcd/serverid.c.
1477 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1479 * Added silc_net_gethostby[addr/name] into the
1480 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1481 routines. Added silc_net_is_ip[4/6]. Affected file is
1482 lib/silcutil/unix/silcunixnet.c. All routines that take
1483 address as argument now supports both IPv4 and IPv6 addresses.
1485 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1487 * Fixed LIST command reply sending in server. Affected file
1490 * Server now sends the kicker's client ID in the KICK notify
1491 to the kicked client. Affected file silcd/command.c.
1493 * The client library now parses the kickers client ID and
1494 UI displays it. Affected files lib/silcclient/client_notify.c
1495 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1497 * Made all payload parsing function prototypes consistent.
1498 They all take now const unsigned char * and uint32 pair as
1499 the payload data instead of SilcBuffer. Changes all around
1500 the source tree. Other unsigned char* -> const unsigned char*
1501 changes around the tree as well.
1503 * Optimized SFTP client and server packet sending not to
1504 allocate new buffer for each packet but to recycle the
1505 first allocated buffer. Affected files are
1506 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1508 * Optimized the SFTP client to use SilcList instead of
1509 SilcDList for requests, because it is faster. Affected file
1510 is lib/silcsftp/sftp_client.c.
1512 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1513 into lib/silccore/silcid.[ch].
1515 Renamed silcpayload.[ch] into silcargument.[ch].
1517 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1519 * If client entry is deleted with active key agreement
1520 session, abort the session.
1522 The silc_client_abort_key_agreement now calls the completion
1523 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1525 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1528 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1530 * Don't use __restrict in older GCC's. Affected file is
1531 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1533 * silc_net_localhost now attempts to reverse lookup the
1534 IP/hostname. Affected file lib/silcutil/silcnet.c.
1536 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1537 command. It can be used to gain founder privileges at
1538 the same time when joining the channel.
1540 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1541 kicker's client ID as well. Updated protocol specs.
1543 Defined that the server must send SILC_COMMAND_IDENTIFY
1544 command reply with error status to client who sent
1545 private message with invalid client ID.
1547 Updated the protocol specification.
1549 * Added silc_server_send_command_reply to send any
1550 command reply. Affected file silcd/packet_send.[ch].
1552 * Added silc_id_payload_encode_data to encode ID payload
1553 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1555 * The server now send IDENTIFY command reply with error
1556 status if client ID in private message is invalid. Affected
1557 file silcd/packet_receive.c.
1559 * Save the server key file with server's IP address in
1560 the filename instead of hostname. The affected file is
1561 irssi/src/silc/core/client_ops.c.
1563 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1565 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1568 * Added libtool support for compiling shared objects in
1569 lib/silcsim. Affected file configure.in.pre and
1570 lib/silcsim/Makefile.am. Original patch by cras.
1572 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1574 * Pid file configuration, and server's config file fixes
1575 patch by toma. Updated CREDITS file.
1577 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1579 * Fixed silc_client_channel_message to not try to decrypt
1580 the message twice if it resolved the destination client
1581 information. This could cause of dropping one channel
1582 message. Affected file lib/silcclient/client_channel.c.
1584 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1586 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1587 lib/silcclient/client.c. This function is used when the SILC
1588 Client is run under some other scheduler, or event loop or
1589 main loop. On GUI applications, for example this may be
1590 desired to used to run the client under the GUI application's
1591 main loop. Typically the GUI application would register an
1592 idle task that calls this function multiple times in a second
1593 to quickly process the SILC specific data.
1595 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1597 * Fixed silc_server_drop() for dropping the supplementary
1598 groups as well, this could cause a security hole on some
1601 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1603 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1606 * Write PID file after dropping privileges. Added -F option
1607 to run server on foreground. A patch by debolaz.
1608 Affected files silcd/server.c, silcd/silcd.c.
1610 * Fixed MOTD to return the MOTD file server name. Affected
1611 file silcd/command.c.
1613 * Added INFO command reply handling to the Irssi SILC Client.
1614 Affected file irssi/src/silc/core/client_ops.c.
1616 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1618 * Fixed the silc_idcache_list_* routines to really support
1619 the dynamic list. Fixes a crash. Affected file is
1620 lib/silccore/silcidcache.c.
1622 * Fixed the LIST command reply to really call LIST command's
1623 pending callbacks. Affected file silcd/command_reply.c.
1625 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1627 * Update conn->local_entry->nickname after giving NICK
1628 command. Affected file lib/silcclient/command.c.
1630 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1632 * Added the [pid] option to the silcd configuration file
1634 Affected files: serverconfig.[ch] and silcd.c
1636 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1638 * Save fingerprint in WHOIS command reply in server.
1639 Affected file silcd/command_reply.c.
1641 * Fixed NICK commands pending callback registration.
1642 Affected file lib/silcclient/command.c.
1644 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1646 * Use ++server->cmd_ident when sending commands in server,
1647 instead of random number. Affected file silcd/command.c.
1649 * Fixed GETKEY command reply to call actually GETKEY pending
1650 command callbacks. Affected file silcd/command_reply.c.
1652 * A bit stricter check for nicknames. Check for same nickname
1653 in NICK command also. Affected file silcd/command.c.
1655 * Do not call INFO command everytime client ID changes, only
1656 during first connecting. Affected file lib/silcclient/client.c.
1658 * Set the new nickname only after successful command reply for
1659 NICK command is returned by server. Affected file
1660 lib/silcclient/command.c.
1662 * Remove nicknames from nicklist during server_signoff notify.
1663 Should fix /NAMES bit more. The affected file is
1664 irssi/src/silc/core/silc-channels.c.
1666 * Added `fingerprint' field to the SilcIDListData in the
1667 silcd/idlist.h to hold the fingerprint of the client's
1670 Send the fingerprint of the client's public key in WHOIS
1673 Affected files silcd/command.c, and silcd/idlist.[ch].
1675 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1676 create fingerprint from given data.
1678 * Show the fingerprint of the client's public key in WHOIS.
1679 Affected files irssi/src/module-formats.[ch] and
1680 irssi/src/silc/core/client_ops.c.
1682 * Format the multiple same nicknames also during JOIN and
1683 NICK_CHANGE notifys. Affected file is
1684 lib/silcclient/client_notify.c.
1686 * Do not print error on screen for invalid private message
1687 payload since it can come if someone is sending private
1688 messages with wrong key. Affected file
1689 lib/silccore/silcprivate.c.
1691 * Fixed multiple concurrent /PING crash. Affected file
1692 lib/silcclient/command.c.
1694 * Changed the wrong ID encoding. All IP addresses must be
1695 in MSB first order in encoded format. They were encoded
1696 wrong and was in LSB format. Affected files are
1697 silcd/serverid.c, lib/silcutil/silcutil.c.
1699 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1701 * Call the `connect' client operation through the scheduler
1702 in case of error. Affected file lib/silcclient/client.c.
1704 * Call the `failure' client operation even if the error
1705 occurred locally during a protocol. Affected file is
1706 lib/silcclient/protocol.c.
1708 * Added support of sending LIST command to router from normal
1709 server. This way normal server can get list of all channels
1710 in the network too. Fixed the channel list sending in the
1711 server too. Affected files are silcd/command.c, and
1712 silcd/command_reply.[ch].
1714 * Added silc_server_update_channels_by_server and
1715 silc_server_remove_channels_by_server. They are used during
1716 disconnection of primary router and in backup router protocol.
1717 Affected file silcd/server_util.[ch], silcd/server.c and
1718 silcd/server_backup.c.
1720 * Fixed channel adding to global list in IDENTIFY command
1721 reply in server. Affected file silcd/command_reply.c.
1723 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1725 * If the incoming packet type is REKEY or REKEY_DONE process
1726 that packet always synchronously. Fixes yet another MAC
1727 failed error on slow (dialup) connections. Affected file
1728 lib/silcclient/client.c and silcd/server.c.
1730 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1732 * Call check_version SKE callback for initiator too. Affected
1733 file lib/silcske/silcske.c.
1735 * Implemented fix for security hole found in the SKE that was
1736 fixed in the specification few days back; the initiator's
1737 public key is now added to the HASH value computation.
1738 Added backwards support for the old way of doing it too, for
1739 old clients and old servers. Affected file is
1740 lib/silcske/silcske.c.
1742 * Enabled mutual authentication by default in SKE. If initiator
1743 is not providing mutual authentication the responder will
1744 force it. This will provide the proof of posession of the
1745 private key for responder. The affected files are
1746 lib/silcclient/protocol.c and silcd/protocol.c.
1748 * Do not cache anymore the server's public key during SKE.
1749 We do mutual authentication so the proof of posession of
1750 private key is done, and if the server is authenticated in
1751 conn auth protocol with public key we must have the public
1752 key already. Affected file silcd/protocol.c.
1754 * Added new global debug variable: silc_debug_hexdump. If
1755 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1756 file lib/silcutil/silclog.[ch].
1758 * Fixed compilation warning due to char * -> const char *.
1759 Affected files lib/silcutil/silcnet.h, and
1760 lib/silccore/silcauth.[ch].
1762 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1764 * Fixed CMODE command when new channel key was created. If
1765 the creation failed the old key was removed. Next time giving
1766 same command would crash the server since the old key was
1767 freed already. Affected file silcd/command.c.
1769 * Fixed the silc_server_announce_get_channels to not crash
1770 on reconnect. Affected file silcd/server.c.
1772 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1774 * Added silc_log_set_debug_string function to set a regex
1775 string to match for debug output. Only the function names,
1776 or filenames matching the given debug string is actually
1777 printed. This way it is possible to filter out those debug
1778 strings that user is not interested in.
1780 Fixed a bug in silc_string_regexify.
1782 Affected files lib/silcutil/silclog.[ch], and
1783 lib/silcutil/unix/silcunixutil.c.
1785 * Changed the -d options in both server and Irssi SILC client
1786 to take the debug string as argument. Affected files
1787 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1789 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1791 * Added silc_hash_babbleprint to create a Bubble Babble
1792 Encoded fingerprint. The encoding is developed by Antti
1793 Huima (draft-huima-babble-01.txt), and it creates human
1794 readable strings out of binary data. Affected file
1795 lib/silccrypt/silchash.[ch].
1797 * Print the babble print now in addition of fingerprint as well
1798 in Irssi SILC client. Affected files are
1799 irssi/src/fe-common/silc/module-formats.[ch],
1800 irssi/src/fe-common/silc/core/client_ops.c.
1802 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1804 * Fixed a security problem found in SKE. The initiator's
1805 public key too is now added to the HASH hash value creation
1806 which is signed by the responder to create the SIGN value.
1807 This will prevent anyone in the middle to lie to the responder
1808 about the initiator's public key. If this is done now, the
1809 man in the middle will get caught. Updated the protocol
1812 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1814 * Better installation directory handling. Configure module
1815 paths and other paths automatically to example_silc* files
1816 in doc/. A patch by toma.
1818 * Fixed compiler warning from MPI library, and from SILC RNG.
1821 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1822 It can be configured with ./configure. A patch by toma.
1824 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Find correct make to use in prepare-clean. A patch by
1827 toma. Affected file prepare-clean.
1829 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1831 * Added irssi variables use_auto_addr, auto_bind_ip,
1832 auto_bind_port and auto_public_ip.
1834 * Changed the interface for silc_client_send_key_agreement
1835 in lib/silcclient/silcapi.h
1839 irssi/src/silc/core/silc-core.c
1841 lib/silcclient/silcapi.h
1842 irssi/src/silc/core/silc-channels.c
1843 lib/silcclient/client_keyagr.c
1846 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1848 * Added silc_pkcs_public_key_compare to compare two
1849 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1851 * Check that the client who set the founder mode on the
1852 channel is the same client that is giving the founder
1853 mode to itself. It is done by comparing the saved public
1854 key (it is saved even in the authentication is passphrase).
1855 Affected file silcd/command.c.
1857 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1859 * Do not process packet for disconnected socket connection.
1860 Affected file lib/silccore/silcpacket.c.
1862 * Process the DISCONNECT packet through scheduler in the
1863 client library. Affected file lib/silcclient/client.c.
1865 * Fixed the silc_client_packet_parse to not to increase
1866 the packet sequence number if the conn->sock and the
1867 current socket connection is not same. This can happen
1868 for example during key agreement when the conn includes
1869 multiple socket connections (listeners). Affected file
1870 lib/silcclient/client.c.
1872 * The sender of the file transfer request now provides also
1873 the pointer (listener) for the key exchange protocol. If
1874 the listener cannot be created then it sends empty key
1875 agreement and lets the receiver provide the listener.
1877 Added `local_ip' and `local_port' arguments to the
1878 silc_client_file_send. If they are provided they are used,
1879 if not then it will attempt to find local IP address, if
1880 not found or bind fails then the remote client will provide
1883 Affected files are lib/silcclient/client_ftp.c and
1884 lib/silcclient/silcapi.h.
1886 * Extended the FILE SEND command to support defining the
1887 local IP and port for key exchange listener. They are
1888 optional. Affected file irssi/src/silc/core/silc-servers.c.
1890 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1892 * Defined to WHOIS command reply the sending of fingerprint
1893 of the client's public key (if the proof of posession of the
1894 corresponding private key is verified by the server).
1895 Updated to the protocol specification.
1897 * Added support of receiving the client's public key's
1898 fingerprint in command reply in client library. Affected
1899 file is lib/silcclient/command_reply.c, and
1900 lib/silcclient/idlist.[ch].
1902 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1904 * Do not send over 128 chars long nickname to the server
1905 in NICK command. Affected file lib/silcclient/command.c.
1907 * Do not send over 256 chars long channel names to the server
1908 in JOIN command. Affected file lib/silcclient/command.c.
1910 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1912 * Assure that silc_server_close_connection cannot be called
1913 twice for same socket context. Affected file is
1916 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1918 * Send error message to application if opening file for
1919 writing during file transfer fails. Affected file is
1920 lib/silcclient/client_ftp.c.
1922 Remove all file transfer sessions for a client that we're
1923 removing from ID cache.
1925 Affected file is lib/silcclient/client_ftp.c.
1927 * Fixed silc_net_addr2bin to return correct address. Affected
1928 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1930 * Fixed file transfer session removing on signoff notify.
1931 Affected file irssi/src/silc/core/silc-servers.c.
1933 * Added the SilcClientFileError to be returned in the monitor
1934 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1935 Affected file lib/silcclient/silcapi.h.
1937 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1939 * Fixed a crash in silc_client_ftp_free_sessions and
1940 silc_client_ftp_session_free_client. Affected file
1941 lib/silcclient/client_ftp.c.
1943 * Added `disabled' field in the SilcChannelEntry in the server
1944 to indicate if the server entry is disabled. Affected file
1945 silcd/idlist.h, silcd/command[_reply].c.

1954 * Fixed a crash in client resolving in client_prvmsg.c in
1955 client library. Affected file lib/silcclient/client_prvmsg.c.
1957 * Do not actually remove the client directly from ID cache
1958 during SERVER_SIGNOFF, but invalidate it. This way we
1959 preserve the WHOWAS info for the client. Affected file
1960 silcd/server_util.c.
1962 * Fixed SERVER_SIGNOFF notify handling in the server. The
1963 server is now able to process incoming SERVER_SIGNOFF notify
1964 for a server that it doesn't even know about. It will remove
1965 the clients provided in the notify. Affected file
1966 silcd/packet_receive.c.
1968 * Check for partial packet in data queue after every packet that
1969 was found from the queue. Return and wait for more data if
1970 there is partial data in queue. Affected file is
1971 lib/silccore/silcpacket.c.
1973 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

1978 Affected files lib/silcclient/silcapi.h and
1979 lib/silcclient/client_ftp.c.
1981 * Check that newsize in silc_buffer_realloc is larger than
1982 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1984 * Added better monitor of file transfers. It now monitors
1985 key agreement protocol during the file transfer too. Added
1986 error reporting too. Affected files
1987 irssi/src/silc/core/silc-servers.c,
1988 irssi/src/fe-common/silc/module-formats.[ch].
1990 * Wrote a help file for FILE command.
1992 * Added silc_rng_global_get_byte_fast to get not-so-secure
1993 random data as fast as possible. Random data is read from
1994 /dev/urandom if available and from the SILC RNG if not
1995 available. It is used in padding generation. Affected file
1996 lib/silccrypt/silcrng.[ch].
1998 * All packets in client library are now processed synchronously.
1999 Optimized packet processing a lot. Affected file
2000 lib/silcclient/client.c.
2002 * All server connection packets are processing synchronously
2003 now in server, to optimize packet processing. Affected file
2006 * Include files are installed now only in Toolkit distribution
2007 if make install is given. Affected files: all Makefile.am's.
2009 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2011 * Assure that silc_client_notify_by_server_resolve does not
2012 resolve the client information multiple times. If it cannot
2013 be found by the first it cannot be found at all. Affected
2014 file lib/silcclient/client_notify.c.
2016 * Fixed WHOWAS command reply calling. Affected file
2017 lib/silcclient/command_reply.c.
2019 * Removed all references to silc_idlist_get_client from the
2020 Irssi SILC client since that call is internal call used by
2021 the library. The Irssi SILC client will use now client
2022 retrieval functions found in silcapi.h.
2024 * Fixed a bug in resolving nickname info before sending
2025 private message. It used freed memory. Affected file
2026 irssi/src/silc/core/silc-servers.c.
2028 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2030 * Assure my_channels statistics cannot go negative in server.
2031 Affected files silcd/server.c, silcd/server_util.c.
2033 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2047 * Added silc_net_localip to return local host's IP address.
2048 Affected file lib/silcutil/silcnet.[ch].
2050 * If key exchange or rekey protocol is active for a connection
2051 parse all packets syncronously since there might be packets
2052 in packet queue that we are not able to process without first
2053 processing packets before them. Affected file silcd/server,
2054 lib/silcclient/client.c.
2056 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2057 whether library should continue processing the packet.
2058 Affected file lib/silccore/silcpacket.h.
2060 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and

2127 Affected file silcd/command.c.
2129 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2131 * Call the silc_server_udpate_servers_by_server in the
2132 primary router that comes back online in the backup resuming
2133 protocol. Otherwise it routes packets wrong. Affected file
2134 silcd/server_util.[ch], silcd/server_backup.c.
2136 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2138 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2139 lib/silcutil/silcbuffmt.[ch].
2141 * Redefined the SILC packet header to include the padding
2142 length. Affected file lib/silccore/silcpacket.[ch].
2144 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2145 length for maximum padding up to 128 bytes). Affected
2146 file lib/silccore/silcpacket.h.
2148 * Removed all backwards support for old 0.5.x MAC thingies.
2149 The SILC packet header change makes it impossible to be
2150 backwards compatible.
2152 * Send the ENDING packet with timeout in the backup resuming
2153 protocol. This is to assure that all routers has connected
2154 to the primary router. Affected file silcd/server_backup.c.
2156 * Changed the RNG to take the first IV from random data. It
2157 used to take it from zero actually. Changed the RNG also
2158 to use /dev/urandom during session. /dev/random is used
2159 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2161 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2163 * Changed the SILC packet header to have the first two bytes
2164 (the packet length) encrypted. Affected files aroung the
2165 code tree, lib/silccore/silcpacket.[ch]. Removed the
2166 SilcPacketCheckDecrypt callback. It is not needed anymore
2167 since the silc_packet_receive_process will determine now
2168 whether the packet is normal or special.
2170 * Implemented the unidirectional MAC keys. Affected files
2171 lib/silcske/silcske.c, silcd/protocol.c and
2172 lib/silcclient/protocol.c.
2174 * Implemented the packet sequence number to the MAC computation.
2175 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2176 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2177 lib/silcclient/protocol.c.
2179 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2181 * Allow backup router to announce servers. All servers
2182 announced by backup router are added to the global list
2183 automatically. Update hte server's socket to our primary
2184 router also when backup router announces a server.
2185 Affected file silcd/packet_receive.c.
2187 * Do not update the client->router in the function
2188 silc_server_udpate_clients_by_server if the client is on
2189 global list. We might fail to find any specific server
2190 for locally connected clients and local cell clients. They
2191 should still use the `from' and not `to' as client->router.
2192 This fixes backup router resuming protocol. Affected file
2193 silcd/server_util.c.
2195 * Decrease channel statistics count only if the channel
2196 deletion worked. Affected files are silcd/server.c and
2197 silcd/server_util.c.
2199 * Added silc_server_update_servers_by_server to update origin
2200 of all server entries. Used during backup router protocol.
2201 Affected files silcd/server_util.[ch], silcd/server.c. and
2202 silcd/backup_router.c.
2204 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2205 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2206 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2207 lib/silccrypt/silchmac.c.
2209 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2211 * Assure that router cannot reroute the same channel message
2212 to the sender. Affected file silcd/packet_receive.c.
2214 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2216 * Made better checks that the channel message is not sent
2217 to the router it came from. Affected file is
2218 silcd/packet_send.c. Fixed memory leak too.
2220 * Announce informations for incoming router connection, but
2221 only after checking if it is replaced by backup router.
2222 Affected file silcd/packet_receive.c.
2224 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2226 * Fixed the backup resuming protocol to work in multiple
2227 router environment. Affected file silcd/server_backup.c.
2229 * Route packet only to one router in the function
2230 silc_server_packet_send_to_channel. Affected file is
2231 silcd/packet_send.c.
2233 * Fixed silc_server_send_notify_dest to set the broadcast
2234 flag. Fixed the silc_server_send_notify_topic to actually
2235 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2236 Affected file silcd/packet_send.c.
2238 * Changed the SFTP Filesystem interface. Changed the
2239 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2240 the filesystem operation function. The SilcSFTPFilesystem
2241 is now a context that is allocated by all filesystem allocation
2242 functions and it already includes the operations structure
2243 and filesystem specific context. It is given as argument
2244 now to the silc_sftp_server_start. This made the interface
2245 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2246 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2248 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * Changed the backup router adding and getting interfaces
2251 in the server. The router that will be replaced by the
2252 specified backup router is now sent as argument. Affected
2253 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2256 * Added silc_net_addr2bin_ne to return the binary form of
2257 the IP address in network byte order. Affected files
2258 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2260 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2262 * Check for existing server ID in silc_server_new_server
2263 and in silc_server_connect_to_router_final and remove the
2264 old entry if it exists. Affected file silcd/packet_receive.c,
2267 * Send the channel message always to only one router, either
2268 in upstream or downstream. Affected file is
2269 silcd/packet_send.c.
2271 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2273 * Wrote the definition of the backup resuming protocol to the
2274 protocol specification.
2276 * Removed one redundant channel key generation from normal
2277 server during joining procedure. Removed one redundant
2278 channel key sending from server to router during joining
2279 procedure. Affected file silcd/command.c.
2281 * Made minor bugfixes to the backup router resuming protocol.
2282 Affected file silcd/server_backup.c, server.c.
2284 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2286 * Added --disable-asm configuration option. Affected files
2287 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2290 * Implemented the backup resuming protocol that is used to
2291 resume the primary router position in the cell after the
2292 primary router comes back online. Affected files
2293 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2294 and silcd/server_util.[ch].
2296 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2298 * Sleep two (2) seconds after sending QUIT command to server.
2299 Affected file lib/silcclient/command.c.
2301 * Assure that if outgoing data buffer is pending do not force
2302 send any data. Affected file silcd/packet_send.c.
2304 * Assure that if outgoing data buffer is pending do not force
2305 send any data. Affected file lib/silcclient/client.c.
2307 * Implemented the backup router support when the primary router
2308 goes down. The servers and routers can now use the backup
2309 router as new primary router without loosing connectivity.
2311 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2313 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2314 in the server to indicate disabled entry. All data read
2315 from the connection will be ignored and no data is sent
2316 for entry that is disabled. Affected files are
2317 silcd/idlist.h, silcd/server.c.
2319 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2321 * Created SFTP client and server test programs in the
2322 lib/silcsftp/tests directory.
2324 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2326 * Implemented memory filesystem (virtual filesystem) for
2327 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2330 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2332 * Implemented the SFTP (SSH File Transfer Protocol) to the
2333 lib/silcsftp. It includes SFTP client and SFTP server
2336 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2338 * Moved lib/silccore/silcprotocol.[ch] to the
2339 lib/silcutil library.
2341 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2342 take variable argument list pointer as argument. Affected
2343 file lib/silcutil/silcbuffmt.[ch].
2345 * Added silc_buffer_set function that is used to set data
2346 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2347 Affected file lib/silcutil/silcbuffer.h.
2349 * Changed various routines in the core library to use the new
2350 silc_buffer_set instead of allocating new buffer only for
2353 * Added 64-bit value formatting and unformatting support to the
2354 silc_buffer_[un]format routines. Affected file is
2355 lib/silcutil/silcbuffmt.[ch].
2357 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2358 to includes/bitmove.h.
2360 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2362 * Fixed channel user mode saving in client library. Affected
2363 file lib/silcclient/command[_reply].c.
2365 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2367 * Defined the file transfer to the SILC Protocol. Added
2368 new packet type SILC_PACKET_FTP and defined File Transfer
2369 Payload. The mandatory file transfer protocol is SFTP
2370 (SSH File Transfer Protocol). Affected file in addition
2371 of the internet draft is lib/silccore/silcpacket.h.
2373 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2374 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2375 is used as part of backup router protocol when the primary
2376 router of the cell is back online and wishes to resume
2377 the position as primary router.
2379 * Redefined the MAC generation keys in the protocol. The
2380 same key is not used anymore in both direction. Both
2381 direction will now use different keys for sending and
2382 receiving. This fixes a potential security flaw. This
2383 change causes incompatibilities in the protocol.
2385 * Redefined also the MAC computation from the packet.
2386 An packet sequence number is now added to the MAC
2387 computation. This prevents possible replay attacks against
2388 the protocol. This change too causes incompatibilities
2391 Added `sequence' field to the SilcPacketContext to hold
2392 the current sequence number for the packet.
2394 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Added `created' field to the SilcIDListData in the file
2397 silcd/idlist.h to indicate the time when the entry was
2400 * Added `created' field to the SilcChannelEntry too. Affected
2401 file silcd/idlist.h.
2403 * Added `creation_time' aguments to all the announcement functions
2404 in the server. If it is provided then only the entries that
2405 was created after the provided time frame are actually
2406 announced. Affected file silcd/server.[ch].
2408 * The protocol says that the Channel ID's IP address must be
2409 based on the router's IP address. Added check for this in
2410 the silc_server_new_channel when processing incoming New Channel
2411 Payload. Affected file silcd/packet_receive.c.
2413 * Print out the correct version with --version in SILC client.
2414 Affected file irssi/src/silc/core/silc-core.c.
2416 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2418 * Fixed WHOWAS command to check for completnes of the client
2419 entry always, not just when the command is coming from client.
2420 Affected file silcd/command.c.
2422 * Added new function silc_server_packet_queue_purge to purge the
2423 outgoing data queue to the network. After the function returns
2424 it is guaranteed that the outgoing packet queue is empty.
2425 Affected file silcd/packet_send.[ch].
2427 * Purge the outgoing packet queue in the rekey protocol's final
2428 callback to assure that all rekey packets go to the network
2429 before quitting the protocol. Affected file silcd/server.c.
2431 * Added silc_client_packet_queue_parse as similar function as
2432 in server to the client library. The affected file is
2433 lib/silcclient/client.c.
2435 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2437 * Splitted silcd/server.c and created silcd/server_util.[ch]
2438 for utility functions.
2440 * Added new socket flag SILC_SF_DISABLED to indicate that the
2441 connection is open but nothing can be sent to or received from
2442 the connection. Affected file lib/silcutil/silsockconn.[ch].
2443 The checking for disabled socket is checked in the low level
2444 silc_socket_write and silc_socket_read functions.
2446 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2448 * Allow only nicknames and channel names that fits into the
2449 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2451 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2453 * When processing JOIN command reply in server check that if
2454 the channel exists in our global list we'll move it the local
2455 list. Affected file silcd/command_reply.c.
2457 * Fixed the check whether client is joined on the channel already
2458 in JOIN command. Affected file lib/silcclient/command.c.
2460 * Fixed the JOIN command reply to check whether the channel
2461 already exists. Affected file lib/silcclient/command_reply.c.
2463 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2465 * Added silc_ske_status_string to map the SKE error numbers
2466 to readable strings. The affected files are
2467 lib/silcske/silcske[_status].[ch].
2469 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2471 * Do not show the private channels on the WHOIS channel list
2472 as it is not allowed by the protocol. The affected file is
2475 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2477 * Assure that the packet length digged from the actual packet
2478 is something sensible in the silc_packet_decrypt_rest_special
2479 in lib/silccrypt/silcpacket.c.
2481 * Free and NULL the allocated pointer in silc_hmac_alloc if
2482 the HMAC allocation fails. The affected file is
2483 lib/silccrypt/silchmac.c.
2485 * Print the selected security properties to the log files in
2486 the server. Affected file silcd/protocol.c.
2488 * Add SKE's reference counter even if calling the completion
2489 callback manually. Otherwise it goes negative, although it
2490 does not cause any problems. The affected file is
2491 lib/silcske/silcske.c.
2493 * Remove the client entry with short timeout after giving the
2494 KILL command. Affected file lib/silcclient/command.c.
2496 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2497 case all found clients are already disconnected (WHOWAS would
2498 found them) in the server. Affected file silcd/command.c.
2500 * Update the last_receive (time of last data received) to be
2501 updated only when received private or channel message so that
2502 the idle time showed in WHOIS makes more sense.
2504 * Added boolean field `valid' in to the SilcClientEntry in the
2505 client library to indicate whether the entry is valid or not.
2506 This fixes the nickname change bug on channel when changing
2507 the nickname to be same than the old (like nick to Nick) the
2508 nickname formatter doesn't set the new nick anymore to Nick@host.
2509 Affected file lib/silcclient/idlist.[ch].
2511 * Now actually fixed the nickname changing on disconnection.
2512 Added new function silc_change_nick to the Irssi SILC Client.
2513 Affected file irssi/src/silc/core/client_ops.c,
2514 irssi/src/silc/core/silc-nicklist.[ch].
2516 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2518 * Check that the public key exists in the GETKEY command before
2519 trying to encode it. Affected file silcd/command.c.
2521 * Print some notifications on received public keys with GETKEY
2522 command in the Irssi SILC Client. Affected files are
2523 irssi/src/fe-common/silc/module-formats.[ch],
2524 irssi/src/silc/core/client_ops.c.
2526 * Use IDENTIFY command to resolve the server information in the
2527 GETKEY command instead of INFO command. Affected file
2528 lib/silcclient/command.c.
2530 * All command reply functions in the client library now calls
2531 the pending command reply callbacks even if an error has
2532 occurred. The server has done this a long time and now it was
2533 time to move the client library to this as well. Now all
2534 errors can be delivered back to the pending command reply
2535 callbacks if necessary. Affected files are
2536 lib/silcclient/command[_reply].[ch].
2538 * Change the nickname on disconnection back to the username
2539 because in reconnect the server will enforce it to it anyway.
2540 Affected file irssi/src/silc/core/silc-servers.c.
2542 * Fixed a config file parsing bug in the Irssi SILC client.
2543 Affected file irssi/src/silc/core/clientconfig.c.
2545 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2547 * When printing the channel mode on JOIN, verify that the
2548 channel key and channel's HMAC are valid. Affected file
2549 irssi/src/silc/core/client_ops.c.
2551 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2553 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2554 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2555 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2557 * Removed channel key rekey task deleting from the function
2558 silc_server_save_channel_key. Affected file silcd/server.c.
2559 Added explicit timeout task context instead that is used to
2560 delete the task if we are registering a new task before the
2561 new task has elapsed.
2563 * When channel key rekey occurs the client library now saves
2564 the old channel key for a short period of time (10 seconds) and
2565 is able to use it in case some is still sending channel
2566 messages encrypted with the old key after the rekey. Affected
2567 file lib/silcclient/[idlist.h|client_channel.c].
2569 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2571 * Added check to the silc_server_new_id_real to not accept
2572 new ID if it is the sender's own ID. Affected file is
2573 silcd/packet_receive.c.
2575 * Assure that we do not announce ourself or the one we've
2576 sending our announcements when we're router and are announcing
2577 servers to our primary router. Affected file silcd/server.c.
2579 * Fixed silc_server_command_identify_check_client to assemble
2580 correct WHOIS packet. It send corrupted WHOIS packet and
2581 caused problem with router to router connections. Affected
2582 file silcd/command.c.
2584 Fixed also silc_server_command_whois_check the same way
2585 as for the IDENTIFY command.
2587 * Added new SilcIDListStatus to the server in the SilcIDListData
2588 structure. The status now includes the current status of
2589 the entry (like registered, resolved etc.). Affected file
2590 silcd/idlist.[ch]. Defined a bunch of different status types
2591 as well. This replaced the old boolean registered field as well.
2593 Added resolve_cmd_ident field to the SilcClientEntry structure
2594 too so that if the entry is for example being resolved so
2595 another command may attach to the same pending command reply
2596 without requiring to resolve the same entry again. This concept
2597 should optimize the WHOIS and the IDENTIFY resolving under
2598 heavy load by taking away unnecessary resolving for entries
2599 that are being resolved already.
2601 Added support for adding multiple pending commands for one
2602 command idenfier. Affected file silcd/command[_reply].[ch].
2604 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2605 before deleting the data. Otherwise the hash table will have
2606 freed data in comparison functions. Affected file is
2607 silcd/command_reply.c.
2609 * Fixed silc_idlist_replace_client_id to add the new entry to
2610 the cache with NULL nickname. Otherwise there will be invalid
2611 memory as the nickname after the nickname is freed. Affected
2612 file silcd/packet_receive.c.
2614 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2615 saved into wrong slots because the previous number of entries
2616 was not taken into account. Affected file silcd/idlist.c.
2617 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2619 * If we are router and we receive JOIN notify to a channel that
2620 does not have any users then notified client is marked as the
2621 channel founder, as it is it. The affected file is
2622 silcd/packet_receive.c
2624 * Added to the extended hash table API's table_del_*ext functions
2625 the destructor as argument too, so that the caller can decide
2626 which destructor to use or whether to use destructor at all.
2627 Affected file lib/silcutil/silchashtable.[ch].
2629 * Fixed ID Cache purging. It actually deleted the entries from
2630 the hash table after the data was freed. The hash table ended
2631 up comparing freed memory. The affected file is
2632 lib/silccore/silcidcache.c.
2634 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2636 * Fixed Irssi SILC client's KILL command's HELP syntax.
2638 * The USERS command now resolves the detailed user information
2639 if the userinfo field is missing. Affected file is
2640 lib/silcclient/command_reply.c.
2642 * Do not print error in silc_file_read if the read file does
2643 not exist. Just silently return NULL. Affected file is
2644 lib/silcutil/silcutil.c.
2646 * Fixed the silc_log_output to not wine about NULL filename
2647 and to not create some bogus " " filename. Affected file is
2648 lib/silcutil/silclog.c.
2650 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2652 * Fixed various printing bugs on the user interface in the
2653 Irssi SILC Client. Minor changes that were forgotten from
2656 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2658 * Fixed the configure.in.pre and the compilation and distribution
2659 environment to support the new autoconf 2.52. That version is
2660 now required to compile the CVS trunk.
2662 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2664 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2665 to generally parse user@fqdn format strings. Affected file
2666 lib/silcutil/silcutil.c.
2668 * Added nickname_format and nickname_force_format fields to the
2669 SilcClientParams structure. The first one defines the format
2670 for the nicknames that the library will enforce if the receives
2671 multiple same nicknames. The second one is boolean value and
2672 can be used to force the library to always enforce the format
2673 to the nicknames regardles whether there are multiple nicknames
2674 or not. This configurable formatting was employed to flexibly
2675 support accessing multiple nicknames from the user interface.
2676 The userinterface can now set the nicknames to what ever format
2677 they prefer. Affected file lib/silcclient/silcapi.h.
2679 Added function silc_client_nickname_format to the file
2680 lib/silcclient/idlist.c. It performs the nickname formatting.
2682 Added new field `hostname´ to the SilcClientEntry context.
2683 It holds the hostname of the client. Affected file is
2684 lib/silcclient/idlist.h.
2686 * Irssi SILC Client sets the nicknames in nick@hostn format.
2687 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2688 irssi/src/silc/core/silc-core.c.
2690 The WHOIS printing now also shows both the real nickname and
2691 the formatted nickname so that user knows how to access the
2692 user if there are multiple same nicknames cached. Affected
2693 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2694 printing formatting too to take the hostname now as a separate
2695 argument. The Affected file is
2696 irssi/src/fe-common/silc/modules-formats.[ch].
2698 * Changed the silc_client_get_clients_local to accept the formatted
2699 nickname as argument. It accepts the real nickname too but the
2700 formatted nickname can be used to find the true entry from
2701 multiple entries. Affected file lib/silcclient/silcapi.h and
2702 lib/silcclient/idlist.c.
2704 * Added nickname_format_parse field to the SilcClientParams.
2705 It is a callback function provided by the application to parse
2706 the nickname out of the formatted nickname string. The library
2707 calls it to get the nickname from the formatted string. Since
2708 the application generally knows better the format of the nickname
2709 string it parses it instead of the library, even though library
2710 encodes the formatted string. If the callback function is not
2711 provided then the library will use the string as is. The
2712 affected file is lib/silcclient/silcapi.h.
2714 * All the nickname strings passed to the client library in
2715 commands are now expected to be formatted nickname strings.
2716 If the command does not support the formatted nickname string
2717 it will assume that the sent string is the actual nickname.
2718 Affected file lib/silcclient/command.c.
2720 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2722 * Added public key authentication support to OPER and SILCOPER
2723 commands in the client library. Affected file is
2724 lib/silcclient/command.c.
2726 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2728 * Changed the get_auth_methdod client operation to be asynchronous.
2729 It can be async if the application resolves the authentication
2730 method from the server during the negotiation. Added new
2731 SilcGetAuthMeth completion callback that the application will
2732 call after resolving the authentication method.
2734 Added function silc_client_request_authentication_method that
2735 the application can use to resolve the authentication method
2736 from the server. Added also SilcConnectionAuthRequest callback
2737 that the library will call after the server has replied. The
2738 application can call this function if it does not know the
2739 current authentication method.
2741 Affected files are lib/silcclient/client.c and
2742 lib/silcclient/silcapi.h.
2744 * The Irssi SILC client now automatically resolves the authentication
2745 method incase any configuration information is not present (and
2746 currently there never is). The affected file is
2747 irssi/src/silc/core/client_ops.c.
2749 * Fixed public key authentication from the client library.
2750 Affected file lib/silcclient/protocol.c. Changed also the
2751 protocol specification about the public key authentication in
2752 the connection authentication protocol. The actual data to be
2753 signed is now computed with a hash function before signing.
2755 * Fixed the public key authentication from the server as well.
2756 Affected file silcd/protocol.c.
2758 * Removed the mlock()'s from the memory allocation routines.
2759 Affected file lib/silcutil/silcmemory.c. The ./configure does
2760 not check anymore for the mlock(). Affected file is
2763 * Fixed USERS command in server to allow the execution of the
2764 command for private and secret channels if the client sending
2765 the command is on the channel. Affected file silcd/command.c.
2767 * Fixed silc_client_get_clients_local to return the clients
2768 count correctly. It could return wrong value. Affected file
2769 lib/silcclient/idlist.c.
2771 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2773 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2774 types. The assembler optimizations seemed not to like 64-bit
2775 data types. The assmebler optimizations thus are now enabled
2776 also for BSD systems as opposed to only enable them for Linux.
2778 * Do not check for threads at all on BSD systems. Affected
2779 file configure.in.pre.
2781 * Removed -n and -h options from the Irssi SILC Client since
2782 they are not used in silc.
2784 * Fixed the prime generation to assure that the first digit
2785 of the generated random number is not zero since our conversion
2786 routines does not like number strings that starts with zero
2787 digit. If zero digit is seen the random number is regenerated.
2788 This caused some corrupted RSA keys when the zero first digit
2789 was met. Affected file lib/silcmath/silcprimegen.c.
2791 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2793 * Fixed WIN32 configuration in the ./configure script.
2794 Fixed to include xti.h on environments that has it.
2795 Patches by Carsten Ilchmann and andrew.
2797 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2799 * Changed the silc_id_create_client_id to be collision
2800 resistant. It is now assured that there cannot be created
2801 two same client ID's. I suspect that some weird bugs in
2802 the server were actually caused by duplicate Client IDs.
2803 Affected file silcd/serverid.[ch]. A router receiving
2804 new ID now also assures and informs the sending server
2805 if the ID caused collision.
2807 * Changed the silc_id_create_channel_id to also assure that
2808 there are no collisions.
2810 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2812 * Statement about ignoring the Mutual Authentication flag when
2813 performing rekey with PFS was a bit misleading. It is ignored
2814 if it was set in the initial negotiation, it cannot be even
2815 set in the rekey. Fixed in the ke-auth draft. Started the
2816 new versions of the protocol drafts in the doc/.
2818 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2820 * Fixed a bug in silc_client_command_identify_save when saving
2821 new channel information. The channel name was no duplicated
2822 and caused crash on exit. Affected file is
2823 lib/silcclient/command_reply.c.
2825 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2827 * Fixed the getkey command handling in the server. Send just
2828 empty OK reply to the sender if the key could not be fetched
2829 (but everything else was ok, like the key just was not available).
2830 Changed the public key parameter to optional in the protocol
2831 specs so that empty OK reply can be sent. Affected file
2834 Added a message to Irssi SILC client to tell to user if the
2835 server did not return a public key.
2837 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2839 * Fixed a channel key regeneration bug. It registered new
2840 timeout tasks exponentially until all system resources were
2841 used. Affected file silcd/server.c.
2843 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2845 * Added the SILC Document generator to the scripts/silcdoc.
2846 It can be used to generate the Toolkit Reference Manual out
2847 of the source tree. Internally it will also use the RoboDoc
2848 generator now imported in util/robodoc.
2850 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2852 * Added couple of return's in rekey protocol if error orccurred
2853 during the protocol. The execution must be terminated.
2854 Affected file silcd/protocol.c. Also, terminate the protocol
2855 always with timeout.
2857 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2859 * The client's Client ID was created initally from the wrong
2860 nickname (it could have been in format nick@host) in the
2861 silc_server_new_client. Affected file silcd/packet_receive.c
2863 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2865 * Added some SILC_LOG_ERROR's to various error conditions
2866 if client could not be added to ID cache. Affected files
2867 silcd/packet_receive.c and silcd/server.c.
2869 * When client's sock->user_data is freed, NULL also the
2870 client->router and client->connection pointers. Added check
2871 for these pointers being NULL to various places around the
2872 code. Affected file silcd/server.c.
2874 * Added client->data.registered == TRUE checks to various
2875 places around the code to assure that unregistered client's
2876 are not handled when it is not allowed. Affected file
2879 * Added `bool registered' fields to all
2880 silc_idlist_[server|client]_get_* routines to indicate whether
2881 the fetched client needs to be registered or not. Affected
2882 file silcd/idlist.[ch].
2884 * Add your own entry as registered to the ID cache in the
2885 server. Affected file server.c.
2887 * Fixed a bug in silc_server_new_server. The SilcServer was
2888 set as the new server's context instead of SilcServerEntry.
2889 This naturally caused some weird bugs.
2891 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2893 * Do not delete the channel rekey task when adding it
2894 for in silc_server_create_channel_key.
2896 * Changed the silc_server_create_channel_key to return
2897 TRUE or FALSE to indicate the success of the channel key
2900 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2902 * Fixed MSVC++ project files and added missing files to
2903 Makefiles under win32/.
2905 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2907 * Do not add TCP_NODELAY flag if the operating system
2908 does not have it defined. Affected files are
2909 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2911 * Fixed buffer overflow from Irssi SILC Client. Affected
2912 file irssi/src/fe-common/core/themes.c.
2914 * Fixed double free in client library in the file
2915 lib/silcclient/client.c when disconnecting from server.
2917 * Applied double free patch from cras to Irssi SILC client.
2918 Affected files irssi/src/core/[modules/expandos].c
2920 * Fixed the disconnection handling to Irssi SILC Client.
2921 The application must call silc_client_close_connection
2922 in ops->connect client operation in case of failure of
2923 the connection. Affected file is
2924 irssi/src/silc/core/client_ops.c.
2926 * Do not set sock->protocol to NULL in the function
2927 silc_client_close_connection after executing the protocol's
2928 final callback since the sock might not be valid anymore.
2929 Affected file lib/silcclient/client.c.
2931 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2933 * Do not enable SILC_THREADS if the linking with libpthread
2934 did not happen. Affected file configure.in.pre.
2936 * Added notion to protocol specification that server must
2937 verify the sent authentication payload with CMODE when
2938 setting the channel founder key. Implemented it to the
2939 server. Affected file silcd/command.c.
2941 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2943 * Added _EXTRA_DIST SILC distribution variable to the
2944 distributions file. It is used to conditionally add extra
2945 files or directories to the specific distribution. Affected
2946 files ./prepare, Makefile.am.pre and distributions.
2948 Removed the `_' from the start of the distribution names.
2951 * Added README.WIN32 for instructions to compile the Toolkit
2954 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2956 * Fixed a double free in disconnection in the server. Affected
2957 file is silcd/server.c.
2959 * Fixed the lib/silcske/groups.c to work now also with GMP
2960 MP library. The string conversion did not work when using
2961 specific base and the base is indicated in the string as well.
2963 * Created win32/ directory which now includes MSVC++ specific
2964 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2965 It will appear only in the toolkit distribution
2967 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2969 * Changed the key material distribution function in case when
2970 the hash output is too short. The data is now concatenated
2971 a bit differently than it used to. Made the change to the
2972 SKE protocol specification.
2974 * Added better GMP detection to configure.in.pre. A patch
2977 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2979 * Fixed a minor bug in SKE that might cause some problem on
2980 some platforms. Affected file lib/silcske/silcske.c.
2982 * Added the cookie checking for initiator in the SKE. It checks
2983 that the responder returns the sent cookie unmodified. The
2984 affected file is lib/silcske/silcske.c. Added new SKE
2985 error type INVALID_COOKIE that can be sent during the
2986 negotiation. Fixed some memory leaks as well.
2988 * Added the "invalid cookie" error message to Irssi SILC client's
2991 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2993 * Added `task_max' field to the SilcClientParams to indicate
2994 the maximum tasks the scheduler can handle. If set to zero,
2995 default values are used. Affected file lib/silcclient/silcapi.h.
2997 * Fixed memory leaks in silc_client_close_connection. Affected
2998 file lib/silcclient/client.c.
3000 * Added silc_client_del_client_entry to client library to free
3001 all memory of given client entry. Affected file is
3002 lib/silcclient/idlist.[ch].
3004 * Added new functions silc_client_del_channel and
3005 silc_client_del_server to delete channel and server entries.
3006 Affected file lib/silcclient/[silcapi.h/idlist.c].
3008 * Removed silc_client_del_client_by_id from silcapi.h.
3010 * Fixed the INFO command to return the server's own info
3011 correctly when querying by Server ID. Affected file is
3014 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3016 * Removed the non-blocking settings in WIN32 code in the
3017 silc_sock_[read/write] and added SleepEx instead. Affected
3018 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3019 of input data is now checked with FIONREAD and ioctlsocket.
3021 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3023 * Call silc_schedule_task_del_by_context in the
3024 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3025 Affected file lib/silccore/silcprotocol.c.
3027 * Call silc_protocol_cancel for active protocols in the
3028 silc_server_close_connection if the funtion
3029 silc_server_free_sock_user_data has not been called.
3030 Affected file silcd/server.c.
3032 * Generic tasks cannot be deleted using the del_by_fd
3033 task deleting function since generic tasks does not match
3034 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3036 * Added a notion to SILCOPER help file that the SILCOPER works
3037 only on router server, not on normal server.
3039 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3041 * Added for WIN32 support for the new scheduler as well.
3042 Affected file lib/silcutil/win32/silcwin32schedule.c.
3044 * Fixed the SHA1 implementation to work on various platforms.
3046 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3048 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3049 API. It is part of the scheduler now. Everything else is
3050 as previously but some functions has changed their names.
3051 Checkout the lib/silcutil/silcschedule.h for the interface.
3052 Updated all applications to use the new interface. Affected
3053 files are lib/silcutil/silcschedule.[ch].
3055 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * Found a bug in the SKE implementation. The HASH value,
3058 specified by the protocol, was not computed correctly. The
3059 public key of the responder was not added to the computation
3060 even though it is mandatory. Affected file lib/silcske/silcske.c.
3061 This unfortunately causes incompatibilities with older
3062 clients and servers.
3064 * Added WIN32 specific network init and uninit functions:
3065 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3066 the Winsock2. Affected file lib/silcutil/silcnet.h and
3067 lib/silcutil/win32/silcwin32net.c.
3069 * Set the socket always to nonblocking mode on WIN32 after
3070 reading data or writing data. Affected file is
3071 lib/silcutil/win32/silcwin32sockconn.c.
3073 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3075 * Fixed various compilation problems under WIN32. Affected
3076 files lib/silcutil/win32/silcwin32thread.c and
3077 lib/silcutil/win32/silcwin32schedule.c.
3079 * Removed all _internal.h #includes from public header
3080 files. Internal headers must never be included from
3083 Removed also the lib/silcske/payload_internal.h file.
3085 * All include files that may be needed (public and some others
3086 included by the public headers) by application developers are
3087 now copied to the ./includes directory. It does not copy any
3088 internal headers. Affected file Makefile.defines.pre and all
3089 Makefile.am's under lib/ and subdirs.
3091 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3093 * Do not change the ~/.silc directory's permissions automatically.
3094 Affected file irssi/src/silc/core/clientutil.c.
3096 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3098 * Do not cancel the protocol in silc_server_close_connection
3099 it might cause recursion. Now cancelled in the function
3100 silc_server_free_sock_user_data. Affected file silcd/server.c.
3102 * Fixed the silc_server_remove_clients_by_server to regenerate
3103 the channel keys correctly finally. Added also new function
3104 silc_server_remove_clients_channels to actually do it.
3105 Affected file silcd/server.c.
3107 * Fixed the silc_server_new_channel to not crash by giving
3108 wrong router to the new channel. Affected file is
3109 silcd/packet_receive.c.
3111 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3113 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3114 which is given as argument to the silc_client_alloc now.
3115 It can be used to configure the client and set various parameters
3116 that affect the function of the client.
3118 * The USERS command in server did not check whether the channel
3119 is private or secret. Affected file silcd/command.c.
3121 * Added new argument to the USERS command in protocol specification.
3122 The USERS command now can take the channel name as argument
3123 as well. Added support for this in client and server and
3124 updated the protocol specs.
3126 * Completed the GETKEY command in client. It can be now used
3127 to fetch also servers public key not only some clients.
3128 Affected files lib/silcclient/command[_reply].c.
3130 * Added silc_client_get_server to return server entry by the
3131 server name. Affected files lib/silcclient/silcapi.h and
3134 * Redefined the IDENTIFY command in protocol specification to be
3135 more generic. It now can be used to query information about
3136 any entity in the SILC Network, including clients, servers and
3137 channels. The query may be based either the entity's name
3138 or the ID. Added support for this in both client and server.
3140 Affected files silcd/command.c and lib/silcclient/command.c
3141 and command_reply.c.
3143 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3144 the _from_client and _from_server functions. Affected file
3147 * Added silc_client_get_channel_by_id_resolve to the file
3148 lib/silcclient/silcapi.h to resolve channel information by
3149 its ID. Added also silc_client_get_channel_by_id that
3150 does not resolve it from the server.
3152 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3154 * Added SilcServerEntry context into the client library
3155 to represent one server. The INFO command now allocates
3156 these to save the resolved server info. For now on the
3157 client library will also keep information about servers,
3158 connected and resolved with INFO.
3160 The INFO command now allocates the SilcServerEntry context
3161 and saves the server info there. The COMMAND_REPLY in
3162 the INFO now returns the parameters to application in
3163 same order as defined in the protocol specification.
3165 The entries are cached in the client->server_cache.
3167 * The INFO command is now issued after received the Client ID
3168 from the server. Affected file lib/silcclient/client.c.
3170 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3171 to the application as the mode changer might be server.
3172 It is guaranteed that NULL is not returned anymore to the
3173 application. Affected file lib/silcclient/client_notify.c.
3175 The ID Type is now also passed to the application so that
3176 it can check whether the returned entry is SilcClientEntry
3179 Added new function silc_client_get_server_by_id to return
3180 the server entry by ID. Affected files are the
3181 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3183 * Do not create the channel in the Irssi SILC Client when issuing
3184 the JOIN command but when received the sucessful JOIN command
3185 reply. Otherwise the channel might get created even though we
3186 could not join it. The Affected file is
3187 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3189 * Fixed a channel joining bug in router. The router must also
3190 check the channel modes, invite and ban lists etc. when serving
3191 the JOIN command sent by normal server. Affected file is
3192 silcd/command.c. The router now resolves the client's
3193 information from the server who sent the JOIN command if it
3194 does not know it, and processes the JOIN command only after
3197 * Changed the SilcCommandCb to take new argument; void *context2.
3198 Affected file lib/silccore/silccommand.h
3200 The second argument in the command callbacks in the server now
3201 includes the SilcServerCommandReplyContext if the command was
3202 called as pending command callback from the command reply.
3203 Otherwise it is NULL. When called as pending the status of the
3204 command reply will be checked and if it was erronous the
3205 error will be sent to the original sender of the command.
3206 This way the client always receives the error messages even
3207 though the server was actually the one who received the error
3208 when it resent the command to router, for example. Affected
3209 files silcd/command[_reply].[ch].
3211 * Fixed sending WHOWAS command's error message to client if
3212 the requested client could not be found. It was missing.
3215 * Changed the CMODE and CUMODE commands reply arguments in the
3216 protocol specification. The Channel ID is now sent in both
3217 of the commands to identify the channel. Implemented this
3218 new feature to the client and server. Affected files
3219 lib/silcclient/command_reply.c and silcd/command.c.
3221 * Made better checks for invite and ban lists in the JOIN
3222 command in server. Affected file silcd/command.c.
3224 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3226 * The server now performs the incoming host IP/DNS lookup
3227 using the silc_socket_host_lookup and thus does not block
3228 the server anymore. Affected file silcd/server.c.
3230 * Completed the multi-thread support for SILC Scheduler in
3231 the lib/silcutil/silcschedule.c.
3233 * Fixed the configure.in.pre to detect the pthread correctly
3236 * Fixed a deadlock in silc_task_queue_wakeup in the file
3237 lib/silcutil/silctask.c.
3239 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3241 * Added new function silc_schedule_wakeup that is used in
3242 multi-threaded environment to wakeup the main thread's
3243 schduler. It needs to be used when a thread adds a new task
3244 or removes a task from task queues. After waking up, the
3245 scheduler will detect the task queue changes. If threads
3246 support is not compiled in this function has no effect.
3247 Implemented the wakeup mechanism to both Unix and WIN32
3248 systems. Affected files are lib/silcutil/silcschedule.[ch],
3249 lib/silcutil/unix/silcunixschedule.c and the
3250 lib/silcutil/win32/silcwin32schedule.c.
3252 * Added new function silc_task_queue_wakeup to wakeup the
3253 scheduler by the specified task queue. Affected file
3254 lib/silcutil/silctask.[ch].
3256 * The silc_socket_host_lookup_start now wakes up the scheduler
3257 after adding the timeout task. Affected file is
3258 lib/silcutil/silcsockconn.c.
3260 * The silc_socket_host_lookup is synchronous now if the threads
3261 support is not compiled in. However, the callback is still
3262 called asyncronously through the scheduler, anyway. Affected
3263 file lib/silcutil/silcsockconn.c.
3265 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3267 * Added new function silc_socket_host_lookup to perform
3268 asynchronous IP and FQDN lookups for the socket connection.
3269 Affected files lib/silcutil/silcsockconn.[ch].
3271 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3273 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3274 that may or may not compile the mutex support in.
3276 Changed the silc_mutex_alloc interface. It allocates the
3277 mutex now to the sent pointer and returns TRUE or FALSE.
3279 Affected file lib/silcutil/silcmutex.h.
3281 * Wrote the SILC Task Queue interface to support multi-threads.
3282 Affected file lib/silcutil/silctask.[ch].
3284 * Wrote the SILC Scheduler to support multi-threads. Affected
3285 file lib/silcutil/silcschedule.c.
3287 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3289 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3290 in lib/silcutil/win32/.
3292 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3294 * Defined SILC Mutex API and SILC Thread API and implemented
3295 them for Unix. Affected files are
3296 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3297 lib/silcutil/unix/silcunixmutex.c and
3298 lib/silcutil/unix/silcunixthread.c.
3300 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3302 * Fixed the silc_server_remove_clients_by_server's channel
3303 key re-generation. The hash table handling was incorrect
3304 and would not work with many channels. Affected file is
3307 * Fixed some memory leaks around the server code.
3309 * Rewrote the silc_server_get_users_on_channel to support IPv6
3310 based Client ID's. Affected file silcd/server.c.
3312 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3313 specification. However, a separate document must be written
3314 to define the detailed signing procedure and the payload
3315 associated with the flag. Defined the flag to the
3316 lib/silccore/silcchannel.h as well.
3318 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3320 * Changed the dynamic tables to static size tables in the
3321 lib/silccrypt/silchmac.c.
3323 * Removed GCC dependencies from the code. A patch by cras.
3325 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3327 * Do not show the error "Error receiving packet bla bla"
3328 in server if it really was not an error (-2 means that reading
3329 is pending). Affected file silcd/server.c.
3331 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3333 * Fixed a possible crash in silc_server_remove_clients_by_server
3334 in silcd/server.c. Fixed there also some memory leaks.
3336 * Fixed the silc_idlist_replace_client_id. It could replace
3337 wrong key in the hash table. Affected file silcd/idlist.c.
3339 * Do not check whether there are global users on the channel
3340 if the channel->global_users is FALSE. Affected functions
3341 silc_server_remove_from_one_channel and
3342 silc_server_remove_from_channels in silcd/server.c. Also,
3343 do not check if the removed client is local as we can be
3344 sure that global client was not removed from the channel
3345 and checking for global users is not needed.
3347 * The silc_server_remove_clients_by_server now re-generates
3348 the channel keys correctly for those channels that had
3349 clients removed from them. Affected file silcd/server.c.
3351 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3353 * Found the reason of random crashes in the server. We weren't
3354 ignoring the SIGPIPE signal (which can be sent in write())
3355 and it crashed the server. Affected file silcd/silcd.c.
3357 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3359 * Assure that sock->user_data is not NULL in the function
3360 silc_server_packet_send in silcd/packet_send.c.
3362 * Disconnect the remote connection if it could not be added
3363 to any ID lists in the server. The affected file is
3366 * Check in silc_server_packet_send[_real/dest] that the
3367 socket is not disconnecting and ignore the data if it is.
3368 Affected file silcd/packet_send.c.
3370 * Define inline to __inline on native WIN32 compilation.
3371 Affected file includes/silcwin32.h.
3373 * Added some explicit type casts for inline code since MSVC
3374 require them. Affected files lib/silcutil/silcbuffer.h,
3375 lib/trq/silcdlist.h and lib/trq/silclist.h.
3377 * Print warning in log files from now on if the packet
3378 decryption fails. Affected file silcd/server.c.
3380 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3382 * Changed the `say' client operation's interface to accept
3383 new `type' argument to indicate the type of the message sent
3384 by the library. The application may filter the library's
3385 messages according the type. The affected file is the
3386 lib/silcclient/silcapi.h.
3388 * Added two new functions to lib/silcclient/silcapi.h:
3389 silc_client_del_client and silc_client_del_client_by_id.
3390 Affected file lib/silcclient/idlist.c.
3392 * Moved the clientincludes.h from includes/ to silc/ and
3393 serverincludes.h from includes/ to silcd/.
3395 * The modes for the CMODE and CUMODE are now passed as
3396 uint32 for application with COMMAND_REPLY. The affected
3397 file is lib/silcclient/command_reply.c.
3399 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3401 * /WHOIS without arguments shows client's own information.
3402 Affected file lib/silcclient/command.c.
3404 * Changed PING to not accept any arguments. The specs
3405 says that client can ping only the connected server so
3406 requiring an argument is not needed. Affected file is
3407 lib/silcclient/command.c.
3409 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3411 * Fixed a fatal bug in private message sending and reception
3412 encryption and decryption when using private message keys.
3413 The implementation was incorrect and did not follow the
3414 specification. It causd that some of the message were
3415 lost since it did not use the sending and receiving keys
3416 as the protocol suggests. This has been fixed and will cause
3417 incompatibilities with older clients when sending private
3418 message encrypted with private message keys. Affected files
3419 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3420 and various other in Irssi SILC Client.
3422 Added `responder' boolean argument to the functions
3423 silc_client_add_private_message_key[_ske] to indicate when
3424 the key is added as responder or initiator of the key
3427 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3429 * Removed the silc_ske_check_version function and created
3430 a SilcSKECheckVersion callback. Added also a function
3431 silc_ske_set_callbacks that is now used to set all SKE
3432 callbacks. The callback functions are not given to
3433 the SKE functions anymore, but this function is used to
3436 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3438 * Added `silc_version' argument to the silc_client_alloc
3439 to define the version of the application for the library.
3440 The library will use the version string to compare it
3441 against the remote host's (usually a server) version
3442 string. Affected file lib/silcclient/silcapi.h
3444 * Added the KE protocol context to Key Agreement context
3445 in client library so that we can abort the SKE if it
3446 is in process when we get timeout. Affected file is
3447 lib/silcclient/client_keyagr.c.
3449 * Do not resolve the client ID forever if it returns in the
3450 first time that such client does not exist. This was done
3451 for example with private message. Affected file is
3452 lib/silcclient/client_prvmsg.c.
3454 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3456 * Do not add regex.h for WIN32. The affected file
3457 includes/silcincludes.h.
3459 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3460 not work yet 100%. It generates the DLL's automatically
3461 when compiling with --with-win32 under cygwin.
3463 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3465 * lib/contrib/regex.c is not compiled on WIN32.
3467 * Added silc_net_get_socket_opt function to the
3468 lib/silcutil/silcnet.h.
3470 * Added includes/silcwin32.h for WIN32 specific includes
3473 * Do not use ptime structure or any of the posix process
3474 functions on WIN32 in lib/silccrypt/silrng.c.
3476 * Added silc_gettimeofday to provide generic function
3477 for struct timeval on all platforms. Added the function
3478 to lib/silcutil/silcutil.h.
3480 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3482 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3483 library as they clearly belong there. As a plus side we
3484 can make the actual socket connection routines platform
3487 Added also new generic function silc_socket_read and
3488 silc_socket_write (that used to be silc_packet_[read/write].
3489 The implementation of these are platform specific.
3491 * Added WIN32 specific routines of silc_socket_[read/write]
3492 to lib/silcutil/win32/silcwin32sockconn.c.
3494 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3496 * Added preliminary support for native WIN32 compilation under
3497 cygwin (using the -mno-cygwin option for GCC) to the
3498 ./configure.in.pre. The --with-win32 now prepares the
3499 compilation for native WIN32.
3501 * Rewrote the SILC Scheduler interface in the file
3502 lib/silcutil/silcschedule.h. The scheduler is now context
3503 based and does not have anymore any global static scheduler.
3504 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3505 and created lib/silcutil/win32 directory for WIN32 based
3508 * Added Unix specific network routines to the
3509 lib/silcutil/unix/silcunixnet.c and the old
3510 lib/silcutil/silcnet.c includes now only generic routines.
3512 Added WIN32 specific network routines to the
3513 lib/silcutil/win32/silcwin32net.c.
3515 * Added Unix specific utility functions from the
3516 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3518 * Added WIN32 SILC Scheduler to the file
3519 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3522 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3524 * Do not handle JOIN notify in the server if the target client
3525 is not registered (idata->registered == FALSE). The affected
3526 file is silcd/packet_receive.c.
3528 * Update the nickrec->founder in event_cumode in the Irssi SILC
3529 client. Affected file irssi/src/silc/core/silc-channels.c.
3531 * Fixed the CUMODE_CHANGE notify handling in the server when
3532 server and router are announcing their clients on channels.
3533 Now the mode changes are saved and notified correctly. The
3534 affected file is /silcd/packet_receive.c.
3536 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3537 They really did not replace the cache entry in the ID Cache.
3538 Now they do that. Affected file silcd/idlist.c.
3540 * Fixed the KICK notify handling in the Irssi SILC client to
3541 update the channel records so that the kicked client does not
3542 appear to be on the channel. The affected file is
3543 irssi/src/silc/core/silc-channels.c.
3545 * Always update the conn->current_channel when executing command
3546 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3548 * Fixed the KILL notify handling in Irssi SILC client to remove
3549 the killed client on all channels.
3551 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3553 * Fixed the silc_parse_command_line to remove extra spaces
3554 from the start and end of the arguments. Affected file is
3555 lib/silcutil/silcutil.c.
3557 * Cancel and free any active protocol in the function
3558 silc_server_close_connection. Affected file silcd/server.c.
3560 * Cancel and free any active protocol in the function
3561 silc_client_close_connction. Affected file is
3562 lib/silcclient/client.c.
3564 * Do not execute the KILL command for clients that are in
3565 history (ie. they are not in the network). Affected file is
3568 * Fixed KILL notify handling, client does not crash anymore.
3569 Affected file irssi/src/silc/core/silc-channels.c.
3571 * Reduced the default packet buffer size from 2048 to 1024 in
3572 lib/silccore/silcpacket.c.
3574 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3575 counter to the SKE context that is incresed when the SKE library
3576 performs async operation outside the library. If the outside
3577 process frees the SKE context and FREED status will be set
3578 and the library will detect after the sync operation that the
3579 libary is freed. The affected files are
3580 lib/silcske/silcske[_status].[ch].
3582 * Resolve the client entry information in the function
3583 silc_client_channel_message to assure that NULL pointer is not
3584 passed as client entry to the application. */
3586 * Fixed the task timeout calculation to assure that there is
3587 never negative timeouts. The affected file is
3588 lib/silcutil/silcschedule.c.
3590 * Fixed the channel user mode notification sending in server.
3591 It was sent point-to-point to the router (or to server by router)
3592 but it needs to be destined to a channel. The routines now
3593 supports sending the channel user mode notifys to the channels
3594 when announcing clients and channels. Affected files are
3595 silcd/server.c and silcd/packet_receive.c.
3597 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3598 It did not actually replace the old channel entry in the cache.
3599 Affected file lib/silcclient/client_notify.c.
3601 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3603 * Fixed a possible crash in silc_packet_send_prepare. It now
3604 assures always that there is enough space in the buffer and
3605 at the tail area of the buffer (for MAC).
3607 Fixed the inbound buffer reallocation in silc_packet_read.
3608 It was old code and did not handle the reallocation correctly.
3611 The affected file is lib/silccore/silcpacket.c.
3613 * Fixed buffer overflow in silc_parse_nickname in the file
3614 lib/silcutil/silcutil.c.
3616 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3618 * make install generates new server keys only if there is not
3621 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3623 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3624 Added check that if the NOREPLY is set then we will not send
3625 the away message. This avoids infinite loop of away messages
3626 if both clients are away. The affected file is
3627 lib/silcclient/client_prvmsg.c.
3629 * Fixed client crash if /NICK was given without arguments.
3630 Affected file lib/silcclient/command.c.
3632 * Server does not send the invite list in INVITE command back
3633 to the client if the list was not altered. Added this notion
3634 to the protocol spec as well. Affected file silcd/command.c.
3636 Fixed possible crash in INVITE command by checking the
3637 value of silc_server_get_client_route command.
3639 * Fixed the INVITE notify type handling. The arguments are now
3640 taken in correct order and client does not crash. The affected
3641 file is irssi/src/silc/core/silc-channels.c.
3643 Removed the "Inviting xxx to channel" message from the
3644 client library away and let the application handle it.
3645 Affected file lib/silcclient/command.c. Added that message
3646 to Irssi SILC client's message formats.
3648 * Fixed CMODE command crash in client. It now checks the
3649 amount of arguments correctly and does not crash. The affected
3650 file is lib/silcclient/command.c.
3652 * Do not create new channel automatically in silc_channels_join
3653 but check whether the channel by that name already exists.
3654 Affected file irssi/silc/core/silc-channels.c.
3656 * Do not send the SERVER_SIGNOFF to router if the disconnected
3657 entity was the router. Affected file silcd/server.c.
3659 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3660 SILC client as it was missing from there.
3662 Added the handling of the KICK notify to the Irssi SILC client
3663 as it was missing. Added "you have been kicked" message to
3664 Irssi SILC client's message modules formats.
3666 Added the handing of the KILL notify to the Irssi SILC client
3667 as it was missing. Added the kill message module formats
3670 The affected file is irssi/src/silc/core/silc-channels.c.
3672 * The router did not save the channel mode the server announced.
3673 Affected file silcd/packet_receive.c.
3675 * Fixed a possible crash in INFO command in server. If the
3676 server did not provide the server info it crashed. Affected
3677 file silcd/command.c.
3679 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Fixed the GETKEY command in the server to check also the
3682 global list. Otherwise the GETKEY would not work correctly
3683 in normal SILC server. Affected file silcd/command.c.
3685 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3687 * Fixed GETKEY crash, it crashed if the command did not succseed.
3689 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3691 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3692 is now real and not just an macro interface to GMP.
3694 Removed the entire GMP from the source tree and imported new
3695 NSS MPI library instead. Reason for removing GMP is that it is
3696 extremely large and compiles extremely slow. The NSS MPI
3697 is only a few files and compiles in less than 10 seconds.
3698 The speed is also about the same as GMP. The MPI is imported
3699 to lib/silcmath/mpi.
3701 If the system has GMP installed we will still use the GMP.
3702 If it is not then the NSS MPI will be compiled.
3704 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3706 * Merged a long nickname (127 characters long) crash bugfix from
3707 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3709 * Merged a freed memory reference bugfix from Irssi CVS tree.
3710 Affected file irssi/src/core/commands.c.
3712 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3714 * Added the server's public key sving and verification to the
3715 server when performing the SKE. This was missing and the
3716 remote server's (or router's) public key was accepted without
3717 checking whether we have it previously or trust it at all.
3718 Affected file silcd/protocol.c.
3720 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Check in the silc_server_timeout_remote if protocol is active
3723 and make sure that the protocol's final callback is called so
3724 that all memory if freed. Affected file silcd/server.c.
3726 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3728 * silc_server_whois_send_reply crashed the server if the nickname
3729 was 127 characters long. Affected file silcd/command.c.
3731 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * Added sanity check to the silc_server_new_client. If the hostname
3734 is provided inside username then check that the provided hostname
3735 really is the same as the resolved one. If the hostname was not
3736 resolved then check it from the public key. Affected file is
3737 silcd/packet_receive.c.
3739 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3740 if the server disconnected us and the connection is not valid
3741 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3743 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3744 the library to the lib/silcutil/silcutil.[ch].
3746 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3748 * Close log file after open. Affected file
3749 lib/silcutil/silclog.c.
3751 * Check whether sock == NULL in silc_client_send_packet and return
3752 if it is. Affected file lib/silcclient/silcclient.c.
3754 * Check rec->entry == NULL in the Irssi SILC Client before
3755 sending the channel message. Affecte file is
3756 irssi/src/silc/core/silc-servers.c.
3758 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3760 * Merged a splitted window bugfix from Irssi CVS tree. The
3761 affected file is irssi/src/fe-text/textbuffer-view.c.
3763 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3764 It did not print nickname.
3766 * Improved the distributions system a bit.
3768 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3770 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3771 irssi/src/fe-text/gui-window.c.
3773 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3774 to in-active server. The affected file is
3775 irssi/src/silc/core/client_ops.c.
3777 * Resolve the client in USERS command reply if the entry does
3778 not have username resolved. The affected file is
3779 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3780 command to WHOIS command to really resolve stuff. The USERS
3781 is not used any more in any critical section so WHOIS can
3782 be used even though it might be slower than IDENTIFY.
3784 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3787 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * Changed the protocol API a bit more consistent in the
3790 lib/silccore/silcprotocol.[ch].
3792 * Changed the following headers to ROBODoc format:
3794 lib/silccore/silcpayload.h
3795 lib/silccore/silcprotocol.h
3796 lib/silccore/silcsockconn.h
3798 All core library headers are now formatted.
3800 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3802 * Fixed a bug in Irssi SILC client; do not show that you are
3803 server/router operator if you really are not. Affected file is
3804 irssi/src/silc/core/client_ops.c.
3806 * Renamed silc_command_free_payload to silc_command_payload_free.
3807 Affected file lib/silccore/silccommand.h
3809 * Added silcmath.h to include the prototoypes of various routines
3810 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3813 * Changed the following headers to ROBODoc format:
3815 lib/silccore/silcchannel.h
3816 lib/silccore/silccommand.h
3817 lib/silccore/silcid.h
3818 lib/silccore/silcidcache.h
3819 lib/silccore/silcmode.h
3820 lib/silccore/silcnotify.h
3821 lib/silccore/silcpacket.h
3822 lib/silcmath/silcmath.h
3824 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3826 * Added checking to the server code not to start the server if
3827 ciphers and stuff are not configured properly. Affected files
3828 silcd/serverconfig.[h] and silcd/server.c.
3830 * Changed the layout of the header files of the public interfaces
3831 in the SILC libraries. The new layout supports ROBODoc
3832 documentation tool (and some others) so that it is easy to create
3833 a library reference manual. All the other headers and source
3834 code must still follow the CodingStyle document. Also source
3835 code must not include these ROBODoc stuffs, only the headers.
3836 Furthermore, all public interface headers must now be named
3837 by using `silc' prefix, example: silcapi.h, silccipher.h.
3838 Some files were renamed due to this. All the other headers
3839 must not be used as public interfaces. I will update the
3840 CodingStyle document later. Changed following headers, so far:
3842 lib/silcclient/silcapi.h
3843 lib/silccore/silcauth.h
3844 lib/silccore/silcprivate.h
3845 lib/silccrypt/silcdh.h
3847 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Removed silc_client_packet_send_flush from the client library
3852 as it is not needed. Affected file lib/silcclient/client.[ch].
3854 * Added printing of message of unresolved authentication method
3855 to the Irssi SILC client. Added it to the module formats.
3856 Removed the same message from the client library.
3858 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Added new distribution feature, DISTLABEL. Every distribution
3861 can define own preprocessor label that can be used in the
3862 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3863 file distributions, acconfig.h.pre and prepare.
3865 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3867 * Added Makefile.defines_int to include the actual definitions
3868 for Makefile.defines.in. Tested the new distribution system,
3869 created distributions and tested installation.
3871 * Added AWAY message printing to the Irssi SILC client. Added
3872 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3874 * Added SCONNECT command to call the SILC's CONNECT command.
3875 Cannot use CONNECT directly since Irssi uses that internally.
3876 Affected file irssi/src/silc/core/silc-servers.c.
3878 Added ACTION local command. It is same as ME command but takes
3879 the channel as mandatory argument.
3881 Rewrote some of the Irssi's help files to suite for SILC
3884 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3886 * Added Makefile.defines[.in] that should for now on be included
3887 in all Makefile.am file in the source tree. That file includes
3888 all common compilation definitions for SILC source tree.
3890 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3892 * Minor changes to the ./prepare script to change the package
3893 name according the distribution name to the configure.in.
3895 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3897 * Created new distribution system. Added file `distributions'
3898 that defines all the distributions that can be created out of
3899 the SILC source tree. The ./prepare script now reads that
3900 file to determine how to prepare the distributions. The
3901 first argument to the ./prepare is the name of the distribution
3902 and second is the version of the distribution. If given
3903 without arguments it creates the default (toolkit) distribution
3904 with the default version (defined in ./prepare).
3906 All Makefile.am files that are subject to the distributions
3907 are now named as Makefile.am.pre. These are ./Makefile.am
3908 and lib/Makefile.am. Others may be changed later.
3910 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3912 * Added invite list, ban list, some key management and connection
3913 error message printing to module formats in the Irssi SILC client.
3915 * Added new silc_client_set_away_message to set the away message
3916 that is back to the person who sent private message. The
3917 affected file lib/silcclient/silcapi.h and the
3918 lib/silcclient/client_prvmsg.c.
3920 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3922 * Fixed the private message sending in the Irssi SILC client,
3923 added local command KEY to the Irssi SILC client.
3925 Added key management and key agreement message formats to the
3926 irssi/src/fe-common/silc/module-formats.[ch].
3928 Added USERS (alias WHO) printing, server/router operator
3929 indication and LIST command printing to the module formats.
3931 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3933 * Fixed channel joining notify handling, cumode notify handling
3934 from Irssi SILC client.
3936 * Added SILC specific module-formats to the Irssi SILC client so
3937 that SILC specific message hilighting, colors etc is possible.
3938 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3940 Added channel mode, channel user mode, actions, notices,
3941 whois and whowas printing to the the module-formats.c.
3943 * Fixed a bug in channel deletion in the server. The channel
3944 is not left to the cache even if the channel founder auth mode
3945 is set when there are no users anymore on the channel. Affected
3946 file silcd/server.c.
3948 * The silc_net_localhost now resolves the entire hostname including
3949 the domain name. Affected file lib/silcutil/silcnet.c.
3951 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Changed the ask_passphrase client operation to be ascynchronous.
3954 It has now a completion callback and a context that the
3955 application must call after it has got the passphrase from
3956 the user. Affected files lib/silcclient/silcapi.h,
3957 lib/silcclient/protocol.c, lib/silcclient/command.c and
3960 Added SilcAskPassphrase callback that the application calls
3961 to deliver the passphrase to the library.
3963 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3964 The public key verification and especially a certificate
3965 verification is asynchronous procedure.
3967 Added new SILC_SKE_STATUS_PENDING status to indicate the
3968 request is pending and a callback will be called to finalize
3971 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3972 indicate that remote end did not send its public key (or
3973 certificate), even though we require it. Added check for this
3974 condition in the SKE. This was a security bug, now fixed.
3976 Defined new SilcSKEVerifyCbCompletion callback that is called
3977 when the verification process is completed.
3979 The affected files lib/silcske/silcske_status.h and
3980 lib/silcske/silcske.[ch].
3982 * Changed the verify_public_key client operation to be async
3983 as well. Defined SilcVerifyPublicKey callback that is used to
3984 indicate the success of the public key verification process.
3986 Changed the server and client to use the new async client
3989 * Changed the Irssi SILC client's internal scheduler to be called
3990 twice as many times as it used to be. As a result the client
3991 should be a bit faster now. Affected file is
3992 irssi/src/silc/core/silc-core.c.
3994 * Added support to Irssi SILC client of asynchronous public key
3995 verification and passphrase inquiry. Affected file is
3996 irssi/src/silc/core/silc-core.c.
3998 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4000 * Do not say "You have left channel %s" in client library.
4001 Moved it to the application. Affected files are
4002 lib/silcclient/command.c and silc/client_ops.c.
4004 * Fixed silc_client_get_clients. Command context was not
4005 duplicated and was freed memory in the callback. Affected
4006 file lib/silcclient/idlist.c.
4008 * Do not say "you are now talking..." on JOIN command in the
4009 client library. The appliation must handle it.
4011 * Do not say ".. changed topic to" in command reply in the
4012 client libary. The application must handle it.
4014 * Fixed TOPIC command sending in the client library.
4016 * Fixed a memory leak in silc_client_command_free in the file
4017 lib/silcclient/command.c.
4019 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4021 * Imported a modified version of Irssi client to the source tree.
4022 The Irssi will be used to create a new client called
4023 Irssi SILC. Imported to irssi/.
4025 Added silc_core_init_finish function to the Irssi. Affected
4026 file irssi/configure.in.
4028 A lot changes in the Makefile.ams around the irssi tree.
4030 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4032 * Do not rehash if the new size is same as the old size of the
4033 hash table, in the silc_hash_table_rehash*. The affected file
4034 lib/silcutil/silchashtable.c.
4036 * Replaced hash_table_del_by_context calls from the server
4037 (when channel->user_list and client->channels) to the
4038 hash_table_del as it is sufficient and faster.
4040 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4042 * Added silc_hash_table_list, silc_hash_table_get and the
4043 SilcHashTableList structure to provide an alternative way to
4044 traverse the hash table. The affected files are
4045 lib/silcutil/silchashtable.[ch].
4047 * Changed the server's idlist routines to use the hash table
4048 routines to optimize the code.
4050 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4052 * Replaced the client entry's `channel' list and channel entry's
4053 `user_list' list to hash tables for optimized lookup. Changed
4054 the code to use the hash table interface around the code.
4055 Affected file lib/silcd/idlist.[ch].
4057 * Added `auto_rehash' boolean argument to the function
4058 silc_hash_table_alloc to indicate whether the hash table should
4059 auto-rehash when it thinks is appropriate time. It will
4060 increase the hash table size if the there is twice as much
4061 entries in the table than the size of the table, and will
4062 decrease the size if there are twice as less entries than
4063 the size of the table.
4065 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4067 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4069 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4071 * silc_idcache_purge_by_context deletes the entry now by context
4072 as it is supposed to do. Affected file lib/silccore/idcache.c.
4074 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4075 client is not anymore valid (WHOWAS givens the info) and not
4076 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4078 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4080 * Removed the `data' and `data_len' arguments from the ID Cache
4081 interfaces and added `name' argument. ID Cache does not handle
4082 anymore the binary data only a names associated with given ID.
4084 * When hashing a Client ID with silc_hash_id the entire ID is
4085 not hashed anymore, instead only the hash of the Client ID is
4086 hashed. This way we can access the Client ID from the cache
4087 with Client ID but with the hash of the ID (which is a hash of
4088 the nickname) as well without any difference in performance.
4090 Added also silc_idcache_find_by_id_one_ext to do one on one
4091 searching when we have the actual ID. Added also function
4092 silc_hash_client_id_compare. The affected files are
4093 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4095 * When hashing the name associated with a ID it is always done
4096 in lowercase. This way we can access the cache without worrying
4097 about case-sensitivity, even though, for example nicknames are
4100 * Fixed a bug in server with channel message sending. It put
4101 wrong ID type as destination ID. The affected file
4102 silcd/packet_send.c.
4104 * silc_idcache_del_by_context now deletes from all hash tables
4105 by context. Affected file lib/silccore/idcache.c.
4107 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4109 * Changed the client library to use the new ID Cache interface.
4110 Changes around the source tree.
4112 * Added silc_hash_table_rehash_ext to rehash with specific
4113 hash function. Affected file lib/silcutil/silchashtable.[ch].
4115 * Added silc_hash_string_compare to compare two strings in the
4116 hash table. Affected file lib/silcutil/silcutil.[ch].
4118 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4120 * Added new function silc_idcache_del_by_context into the
4121 lib/silccore/idcache.[ch].
4123 * Changed the server's ID list routines to use the new ID Cache
4124 interface. Changes around the source tree.
4126 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Added silc_hash_table_del[_by_context]_ext functions in to the
4129 lib/silcutil/silchashtable.[ch].
4131 Removed silc_hash_table_find_all* routines and added new
4132 silc_hash_table_find_foreach to replace them.
4134 Added silc_hash_table_replace_ext function as extended
4135 replacing function. Separated the simple hash table interface
4136 from the extended hash table interface in the file
4137 lib/silcutil/silchashtable.h.
4139 * Fixed minor bugs and changed it to use some of the new
4140 hash table functions in lib/silccore/idcache.c
4142 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4144 * Added new function silc_hash_table_find_all to return all keys
4145 in the hash table by the specified key. As the hash table is
4146 collision resistant it also makes it possible to have several
4147 duplicate keys in the hash table. This function may be used to
4148 find all of the keys from the hash.
4150 Added user_context arguments to the SilcHashFunction,
4151 SilcHashCompare and SilcHashDestructor to deliver user specified
4154 Added new fuctions silc_hash_table_find[_all]_ext to do
4155 extended lookup with specified hash and compare functions and
4156 specified user contexts.
4158 Added new function silc_hash_table_add_ext to add the key
4159 with specified hash function and user context.
4161 Added new function silc_hash_table_foreach to traverse all
4162 entrys in the hash table. Added SilcHashForeach callback
4165 Added new function silc_hash_table_del_by_context to delete
4166 the entry only if the context associated with the key matches.
4168 Affected files are lib/silcutil/silchashtable.[ch].
4170 * Removed silc_hash_[server/client/channel]_id and added just
4171 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4172 silc_hash_id_compare to compare two ID's using as the hash table
4173 comparison function. Added also silc_hash_data to hash
4174 binary data and silc_hash_data_compare to compare it.
4176 * Removed silc_idlist_find_client_by_hash as it is not needed
4177 anymore. Affected file silcd/idlist.[ch].
4179 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4180 to use internally the SilcHashTable. The new ID Cache is a lot
4181 faster than the old one. Some of the ID Cache interface was also
4182 rewritten and obsolete and stupid functions were removed.
4184 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Added entry_count field to the SilcHashTable to keep the number
4187 of the entries in the table. Implemented the function
4188 silc_hash_table_rehash. Added new function
4189 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4191 Fixed a minor bug in silc_hash_table_free.
4193 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4194 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4195 into the lib/silcutil/silcutil.[ch].
4197 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4199 * Implemented a collision resistant hash table into the
4200 lib/silcutil/silchashtable[ch]. See the header and the source
4201 for the SilcHashTable API.
4203 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Merged dotconf version 1.0.2 into lib/dotconf.
4207 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4209 * Do not compile anything in lib/silcsim/* if the SIM support
4210 is not enabled. The tree should now compile without problems
4213 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4215 * Compiled the SILC under cygwin. Compiled and tested briefly
4216 without problems. More tests needed. The SIMs didn't compile
4219 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4221 * Fixed possible crash in silc_get_username in the
4222 lib/silcutil/silcutil.c.
4224 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4226 * Fixed a va_arg in silc/client_ops.c.
4228 * Oops, RC5 routines were named AES and caused some problems
4229 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4231 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4233 * Added new SilcIDIP structure into the lib/silccore/id.h and
4234 replaced the old `ip' fields from all SILC ID's to that type.
4235 This is a step towards IPv6 support.
4237 The silc_id_get_len takes now the ID as an extra argument.
4238 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4239 both IPv4 and IPv6 based ID's.
4241 The affected files are lib/silccore/id.[ch] and other files
4242 around the tree using these routines.
4244 * Removed the ID length arguments in server from various
4245 silc_server_send_notify_* routines -> they are not needed
4248 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4250 * Fixed memory leak in silc_encode_pem_file in the file
4251 lib/silcutil/silcutil.c.
4253 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4255 * Check minor version as well in the SKE. Affected files are
4256 silcd/protocol.c and lib/silcclient/protocol.c.
4258 * Added --identifier option to the server so that an identifier
4259 can be when creating the public key for the server. Affected
4260 file is silcd/silcd.c.
4262 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4263 lib/silccrypt/silcpkcs.c.
4265 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Register default ciphers and stuff when using -C option with
4268 the server. Affected file sildc/silcd.c.
4270 * Put back the servers public key filename format, it is better
4271 than the new one. For now, the client keys are saved with the
4272 new filename format. The affected file silc/client_ops.c.
4274 * Implemented the Cipher API for the rest of the ciphers that
4275 did not implement it or implemented it the wrong way.
4277 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4279 * Register default ciphers and stuff when using the -S option
4280 in the client. Affected file silc/silc.c. Same also when
4281 creating new key pair with -C option.
4283 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Fixed the silc_verify_public_key client operation function to
4286 save the public keys differently. The fingerprint is now
4287 used as filename and not the hostname. This way also the
4288 client keys are saved uniquely and not with hostnames. The
4289 affected file is silc/client_ops.c.
4291 * Trimmed the silc_hash_fingerprint function to remove extra
4292 whitespaces from the end of the fingerprint. The affected
4293 file is lib/silccrypt/silchash.c.
4297 * Added silc_cipher_register_default function to register all
4298 default ciphers. It can be used when configuration files
4299 does not exist and the application does not want any specific
4300 ciphers in any specific order.
4302 The SilcDList is now used as silc_cipher_list dynamically
4303 allocated cipher list. Removed the static list all together
4304 and now all ciphers must be allocated to the dynamic list.
4305 The silc_cipher_alloc routine was changed to check only the
4308 All silc_cipher_* routines that used to return int returns
4311 The affected files lib/silccrypt/silccrypt.[ch].
4313 * The same thing was done to silc_hash_* as for silc_cipher_*
4314 routines. Affected files lib/silccrypt/silchash.[ch].
4316 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4317 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4318 Added also silc_pkcs_[un]register[_default] functions.
4319 Removed the data_context from the PKCS API.
4321 * Added silc_hmac_register_default function to register default
4322 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4323 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4324 to unregister all hmacs at once.
4326 * Register the default ciphers, hash functions, PKCSs and HMACs
4327 if client's configuration file does not exist. The affected
4330 * The client did not load the hash functions from the SIM
4331 modules at all. Added support for this. Affected file is
4332 silc/clientconfig.c.
4334 * When decoding public key with silc_pkcs_public_key_decode, check
4335 the supported algorithm only if PKCS are registered. Affected
4336 file lib/silccrypt/silcpkcs.c. The same was done with the
4337 silc_pkcs_private_key_decode.
4339 * Fixed the SILC List routines to keep the list always in order.
4340 It used to change the list's order when traversing the list but
4341 not it preserves the order. Affected file lib/trq/silclist.h.
4343 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4345 * Added the client library to use the SilcSocketConnection's
4346 reference counter (by silc_socket_dup) to prevent the bug that
4347 the socket object may be freed underneath async operation.
4349 * The name resolv library checking fixes in the configure.in.pre.
4352 * Created new version of the protocol drafts for future
4353 development. The -03 drafts are the ones that will be changed
4354 in the trunk now and the -02 will remain as they are.
4356 * Send list of CUMODE notifys to the router when announcing
4357 the channel users to the router. Affected file silcd/server.c.
4358 If the router receiving channel founder CUMODE for a channel
4359 that already has channel founder it will send CUMODE notify
4360 to the sender to remove the channel founder rights from the
4361 announced client. Affected file silcd/packet_receive.c.
4363 * The CUMODE notify may now use Server ID as well as the entity
4364 who changes the mode. Updated protocool specs.
4366 * Updated INSTALL and README files.
4368 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4370 * New web pages in the http://silc.pspt.fi. The pages was
4375 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4377 * Implemented the [DenyConnectin] config section in the server.
4378 Added silc_server_config_denied_conn to check whether incoming
4379 connection is denied. Affected file silcd/serverconfig.[ch].
4381 * Do not check the ports when checking the incoming configuration
4382 data if the port is 0, meaning any. Affected file is
4383 silcd/serverconfig.c.
4385 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4387 * Fixed buffer overflow in silc_string_compare in the file
4388 lib/silcutil/silcutil.c.
4390 * Fixed double free in silc_server_command_leave in the file
4393 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4395 * Fixed the version checking in the server. Affected file is
4398 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4400 * Fixed the configuration data fetching when accepting new
4401 connections in the server. Affected file silcd/server.c.
4403 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4405 * Added `sender_entry' argument to the function
4406 silc_server_packet_relay_to_channel so that we can check
4407 whether some destination actually belongs to the same route
4408 the sender belongs (ie, we must not resend the packet to the
4409 sender). Affected file silcd/packet_send.[ch].
4411 * Added `servername' field to the SilcClientEntry in the server
4412 to hold the name of the server where client is from. Affected
4413 file is silcd/idlist.h.
4415 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4417 * Moved the channel message encrypting in the router betwen
4418 router connections from silc_server_channel_message to the
4419 silc_server_packet_relay_to_channel since we want to check
4420 whether we have anybody channel before encrypting anything.
4421 Affected files silcd/packet_[receive/send].c.
4423 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4425 * Fixed the [AdminConnection] server config section to support
4426 multiple entries. Affected file silcd/serverconfig.c.
4428 * Added support into the server to check the validity of the
4429 incoming connection before executing any KE or authentication
4432 * The connection configuration is now saved to the KE and
4433 connection auth protocol contexts and not fetched anymore in
4434 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4436 * The local hosts listenning address and port is also resolved
4437 now when starting the server. We want to have the socket object
4438 to include the real address and port for the listener. Added
4439 new function silc_net_check_local_by_sock into the files
4440 lib/silcutil/silcnet.[ch].
4442 * Fixed a broadcast bug in server -> do not broadcast if we
4445 * Fixed a routing bug. Do not route broadcast packets ever.
4446 Broadcast packets must be processed always and not routed since
4447 they may be destined to some other host than yourself and thus
4448 would get routed without no good reason. Affected file is
4451 * Added function silc_server_config_is_primary_route to check
4452 whether primary router connection has been configured (a router
4453 configuration that we are initiating). If there is not, we
4454 will assume that there is only two routers in the SILC network
4455 and we will use the incoming router connection as our primary
4456 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4458 * Changed the order of the broadcasting. Broadcast _after_ the
4459 packet has been processed not before. Affected file is
4462 * Fixed a [ClientConnection] parsing bug. The port was never
4463 parsed correctly thus resulting to port 0. Affected file
4464 silcd/serverconfig.c.
4466 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4467 argument and did not set the broadcast packet flag. Affected
4468 file silcd/packet_send.c. Fixed same bug in the function
4469 silc_server_send_notify as well.
4471 * If we receive NEW_ID packet for our own ID in the server, ignore
4474 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Removed the nickname from the Private Message Payload.
4479 Updated the code and the protocol specs.
4481 * Updated protocol specs for submitting to the IETF.
4483 * Tweaked the Random Number Generator a bit. Affected file
4484 lib/silccrypt/silcrng.c. Exported a new function
4485 silc_rng_[global]_add_noise which can be used to add more
4488 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4490 * Do not parse packets with different timeout when protocol
4491 is active -> may cause problem with rekey. Affected file
4494 * When server receives signoff notify it must not create
4495 new channel key if the client is on any channels since the
4496 sender of the signoff notify will create it.
4498 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4500 * Added printing of error messages during SKE protocol from the
4501 failure packet sent by server during SKE. Affected file
4504 * Removed the client's failure_callback handling with timeout
4505 and handle it immediately when received.
4507 * The SKE library returned wrong type in SUCCESS and FAILURE
4508 packets. They must be 32 bit MSB not 16 bit MSB.
4510 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4512 * Ok, rewrote the logic of the re-key and now it seems to work.
4513 I tested it on high traffic with frequent re-keys without
4514 problems. Added hmac_receive (and renamed hmac to hmac_send)
4515 in SilcClientConnection in lib/silcclient/client.h and
4516 in SilcIDListData in silcd/idlist.h. Also, removed the
4517 SilcPacketParserContext's cipher and hmac fields as they are
4518 not needed anymore and actually caused some problems when
4519 the ciphers and hmac's changed underneath the packet parser.
4521 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * If re-key protocol is active then process the incoming packets
4524 synchronously since we must assure that icoming packets encrypted
4525 with the old key is processed before the new keys is set to
4526 use. This is true other packets than for REKEY packets.
4527 Affected file silcd/server.c. The same was done to client library
4528 as well, affected file lib/silcclient/client.c.
4530 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Fixed bug in client and server to accept the force send if
4533 the packet is send from silc_[server/client]_packet_process
4534 function. Otherwise the packets are never delivered, oops.
4536 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4538 * Disable force sending of packets when REKEY protocol is active.
4539 We must assure that no packet is sent directly when rekey is
4540 performed. All packets must be sent through packet queue.
4541 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4542 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4543 function is silc_[server/client]_packet_send_real to check
4546 * Replaced the SIM paths from example config files to
4547 /usr/local/modules. Also, make install creates now
4548 /usr/local/silc/logs directory to hold all the SILC server
4551 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4553 * Made the configure.in.pre work on Solaris. Patch by salo.

4562 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * When MAC computation fails the silc_packet_decrypt returned 0
4565 even though it was supposed to return -1. Fixed this. The
4566 affected file is lib/silccore/silcpacket.c.
4568 * Do not replace the config files in /etc/silc (in make install)
4569 if they already exist. Affected file ./Makefile.am.
4571 * Do not send re-key packets immediately but through packet queue.
4572 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4574 * Changed silc_net_check_host_by_sock to return FALSE if the
4575 IP/DNS could not be resolved. Though, it returns the IP address
4576 now even if it could not resolve it (but returns also FALSE).
4577 Affected file lib/silcutil/silcnet.[ch].
4579 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4581 * Added silc_pkcs_decode_identifier to decode the public key's
4582 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4583 Added also silc_pkcs_free_identifier. Added also new context
4584 SilcPublicKeyIdentifier.
4586 * Added -S option to the silc client. It is used to dump the
4587 contents of the specified public key file.
4589 * Changed the PKCS api to return the public key length when
4590 setting the public key.
4592 * Fixed a fatal bug in the public and private key file loading.
4593 Affected file lib/silccrypt/silcpkcs.c.
4595 * Execute the packet parsing for client with zero (0) timeout
4596 if the protocol is active. Affected file silcd/server.c.
4598 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4600 * Made the key generation options to the silcd program. Added
4601 -C option, equivalent to client's option.
4603 * Added new [ServerKeys] config section to the server. It
4604 configures the server's public and private key.
4606 * Defined generic Public Key Payload into the protocol
4607 specification to send specific type of public keys and
4610 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4611 public key or certificate.
4613 * Implemented the GETKEY command to the server and to the
4614 client library and on user interface.
4616 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4648 lib/silcclient/client.h.
4652 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4654 * Do not ask whether user wants to use the negotiated private key
4655 for private messages, just use it. Affected file is
4656 silc/local_command.c.
4658 * Added `send_enc_key' and `enc_key_len' fields to the
4659 SilcIDListData structure since they are needed in the re-key

4679 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4680 int64 of at least the xintXX size. If void * is less that 4
4681 bytes uint32 * will be used. Defined bool as boolean.
4683 * Changed _ALL_ unsigned long and unsigned int to uint32,
4684 unsgined short to uint16 in the source tree.
4686 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4687 not handle clients that has entry->data.registered == FALSE.
4688 They are not in the network anymore. Affected file is
4691 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4693 * Implemented the sending of the SERVER_SIGNOFF notify in the
4694 server. Affected file is silcd/server.c.
4696 * Added silc_server_send_notify_args into silcd/packet_send.[ch].

4705 implemnted the printing of the SERVER_SIGNOFF info to the
4706 application. Affected file silc/client_ops.c.
4708 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4709 if the deleting was successful. Affected file silcd/idlist.[ch].
4711 * Added support for public key authentication in the connection
4712 authentication protocol in the client library. Affected file
4713 lib/silcclient/protocol.c.
4715 * Changed the server's silc_idlist_get_clients_by_* interface
4716 to support already allocated array so that new entries may be
4717 added to pre-allocated array. Affected file silcd/idlist.[ch].
4718 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4719 and command replies.
4721 * All command reply functions in the server now calls the
4722 pending command callback even if error occured. This way the
4723 error will be delivered to the client as well. Affected files
4724 silcd/command.c and silcd/command_reply.c.
4726 * Fixed INFO command to return local server's info if no server
4727 was provided. Affected file lib/silcclient/command.c.

4755 * Added SILC_UMODE_GONE mode to indicate when the client is not
4756 present in the SILC network. Added also support to the local
4757 command AWAY that will set this mode. Added support of showing
4758 "xxx is gone" in WHOIS command. The USERS command shows the
4759 gone status as well.
4761 * Fixed setting server and router operator privileges in the
4762 server's UMODE command. Affected file silcd/command.c.
4764 * Merged the SKE KE1 and KE2 payloads into one payload. The
4765 new KE payload is equivalent to the old KE2 payload.
4767 Cleaned up the SKE Start Payload parsing. It now uses the
4768 simple buffer unformatting to do the parsing. A lot faster
4771 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4772 to the SKE that is used to indicate whether both of the SKE
4773 parties should perform authentication. By default only the
4774 responder performs authentication. By setting this flag also
4775 the initiator must do authentication. By default it is unset
4776 since in normal SKE case, client to server connection, only
4777 the responder should do authentication. When doing SKE between
4778 two clients both should perform authentication. Updated the
4779 code and the protocol specs.
4781 * A little fix to IDENTIFY command in the server. Search the
4782 client first by hash not nickname. Affected file is
4785 * Fixed the silc_client_close_connection to support closing
4786 the client to client connections wihtout deleting too much
4787 data. Affected file lib/silcclient/client.c.
4789 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4790 are received if protocol used to be active but is not anymore
4791 the application would crash due to NULL pointer dereference.
4792 Affected files silcd/server.c and lib/silcclient/client.c.
4794 * Added `hash' field to the SilcClientConnection to include
4795 the hash function negotiated in the SKE protocol.
4797 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4798 to set the channel founder authentication data. A client can
4799 claim the founder rights later by providing the authentication
4800 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4801 This way the channel founder can regain the channel founder
4802 privileges even it is left the channel. This works only on
4803 local server and the client must be connected to the same
4804 server to be able to regain the founder rights. Updated the
4805 protocol specs accordingly.
4807 Added support to the CMODE command in the client to set the
4808 founder auth data. Read the README to see how to set it.
4810 Added support to the CUMODE command to claim the founder
4811 rights. Read the README to see how to do it.
4813 Added support for the founder authentication to the Channel
4814 Entry in the server. Affected file silcd/idlist.h.
4816 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4817 server's CMODE command. Affected file silcd/command.c.
4819 * Added the following new functions into lib/silccore/silcauth.[ch]:
4820 silc_auth_get_method and silc_auth_get_data.
4822 * The server now saves the remote hosts public key to the
4823 SilcIDListData pointer. Affected file silcd/protocol.c.
4825 * The normal server now does not remove the channel entry from
4826 the cache if the founder authentication data is set. It used
4827 to remove it if the founder was the last one on the channel on
4828 the server and left the channel. The auth data is saved and
4829 if the channel is re-joined later the old entry is used with
4830 the old auth data. Affected files silcd/command_reply.c and
4833 * Removed the `pkcs' field from the SilcIDListData structure
4834 in the server; it is not used. Affected file silcd/idlist.h.
4836 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4838 * Fixed packet processing on slow links. Partial packets were
4839 never re-processed because the incoming data buffer was cleared
4840 by the application. Application must not directly clear the
4841 sock->inbuf, the packet processing routines handle it. Fixed
4842 this in client library and in server.
4844 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Fixed the WHOIS and IDENTIFY send reply function to really
4847 check whether to send list or just one entry. Affected file
4850 * Cleaned up the LEAVE command's channel key distribution. The
4851 affected file silcd/command.c.
4853 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4854 can enforce the channel mode as well. In that case the ID
4855 includes the ID of the server. The code now enforces the
4856 mode change if the router have different mode than the server.
4858 * The notify client operation with CMODE_CHANGE notify can now
4859 return NULL client_entry pointer if the CMODE was not changed
4860 by client. Application must check for this.
4862 * Added <Server ID> argument to INFO command to support server
4863 info fetching by Server ID.
4865 * Added silc_server_announce_get_channel_users to get assembled
4866 packets of channel users of the specified channel. Affected
4867 file silcd/server.[ch].
4869 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4870 was freed underneath the ID Cache.
4872 * Re-announce clients when the server received CHANNEL_CHANGE
4873 notify from the router. Affected file silcd/packet_send.c.
4875 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4877 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4878 crashed since it did not handle the fact that there is no cipher
4879 called "3" and didn't check the error condition. Now fixed.
4881 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4882 flag. It can be used to send message requests.
4884 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4886 * Implemented the RESTART command in the client.
4888 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4889 notice type messages. Added notice printing to the user
4892 * The channel keys are not re-generated if the channel's mode
4893 is PRIVKEY, ie private key on the channel exists. Affected
4894 files silcd/server.c and silcd/command.c.
4896 * Fixed a little bug in channel message delivery when channel
4897 private keys are set in the server. Affected file is
4898 silcd/packet_send.c.
4900 * Changed the setting on channel->on_channel = TRUE from the
4901 silc_client_save_channel_key to the JOIN command reply. The
4902 key payload is not received if the private channel key is set.
4903 Affected file lib/silcclient/command_reply.c and the
4904 lib/silcclient/client_channel.c.
4906 * When the CMODE_CHANGE notify is sent and the channel private
4907 key mode is removed the channel key must be re-generated in
4908 other cells as well. Added this support for the router in the
4909 silcd/packet_receive.c.
4911 * Added new local command NOTICE to send notice message on
4912 channel. Affected file silc/local_command.[ch].
4914 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4916 * Added new local command ME to the client. It is used to send
4917 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4918 some action. Affected file silc/local_command.[ch].
4920 * Changed channel_message and private_message client operations
4921 to deliver the message flags to the application. Added also
4922 the `flags' arguments to the silc_client_send_channel_message
4923 and silc_client_send_private_message functions. Affected file
4926 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * Redefined the Private Message Payload to support private message
4929 keys and to support the new private message flags. Updated
4930 the protocol specs. Flags makes it possible to have for example
4931 CTCP style messages.
4933 * Added new type SilcPrivateMessagePayload and defined an API
4934 for it in the lib/silcclient/silcprivate.[ch].
4936 * Tested private message private keys successfully. Tested the
4937 private message key set, unset and list commands with the new
4940 * Redefined the Channel Message Payload to include the channel
4941 message flags (equal with private message flags) to support
4942 for example CTCP style messages.
4944 * Defined some of the message (for channel and private message)
4945 flags. Updated the protocol specs and added the flags to the
4946 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4948 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4950 * Added SilcKeyAgreementStatus type to the key agreement routines
4951 to indicate the current status and error if one occured.
4952 The status types are defined in the lib/silcclient/silcapi.h.
4954 * Added new local command KEY that is used to set and unset private
4955 keys for channels, set and unset private keys for private messages
4956 with remote clients and to send key agreement requests and
4957 negotiate the key agreement protocol with remote client. The
4958 key agreement is supported only to negotiate private message keys,
4959 it currently cannot be used to negotiate private keys for channels,
4960 as it is not convenient for that purpose.
4962 * Fixed a minor pending callback setting bug in the function
4963 silc_client_get_client_by_id_resolve, now the function works.
4964 Affected file lib/silcclient/idlist.c.
4966 * Added function silc_net_get_local_port to get local bound
4967 port by socket. Added to lib/silcutil/silcnet.[ch].
4969 * Added `sockets' and `sockets_count' fields to the SilcClient
4970 object. They hold the sockets of the listenning sockets in
4971 the client. Listenning sockets may be for example the key
4972 agreement server. Affected file lib/silcclient/client.[ch].
4973 Added functions the silc_client_add_socket and the
4974 silc_client_del_socket. They are exported to the application
4977 * Added ~./silc/clientkeys to support other client's public keys.
4979 * Renamed verify_server_key client operation to verify_public_key
4980 and added one argument to indicate the type of the connection
4981 (server, client etc.).
4983 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4985 * Added silc_server_connection_auth_request to handle the
4986 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4987 silcd/packet_receive.[ch].
4989 * Added silc_server_send_connection_auth_request into the
4990 silcd/packet_send.c to send the connection auth request packet.
4992 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4995 * Fixed the public key authentication in responder side in the
4996 server. The `auth_data' pointer includes the SilcPublicKey
4997 not the path to the public key. Affected file silcd/protocol.c.
4999 * Implemented the public key authentication in the initiator side
5000 in the server. Affected file silcd/protocol.c.
5002 * Removed the [RedirectClient] config section from the server
5003 configuration. Is not needed and I don't want to implement it.
5005 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5007 * Cleaned up the CMODE command in the server. It now works
5008 correctly and supports all the modes defined in the protocol.
5009 Affected file is silcd/command.c.
5011 * Added `hmac_name' field to the SilcChannelEntry in the server
5012 to hold the default HMAC of the channel. It can be set when
5013 creating the channel (with JOIN command). Affected files
5016 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5017 type to indicate the change of the current cipher and hmac
5018 on the channel. Client can safely ignore the <cipher> argument
5019 (if it chooses to do so) since the CHANNEL_KEY packet will
5020 force the channel key change anyway. The <hmac> argument is
5021 important since the client is responsible of setting the new
5022 HMAC and the hmac key into use.
5024 * Fixed the CMODE command in the client library as well.
5026 * Tested CMODE command in router environment successfully.
5028 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Show the version of the remote client (or server) when connecting
5031 to the server. It is logged to the log file. Affected file
5032 is silcd/protocol.c.
5034 * Fixed the KILLED notify handling in the client library. The
5035 client must be removed from all channels when receiving the
5038 Also, do not remove the client entry when giving the KILL
5039 command but when the KILLED notify is received.
5041 * Removed silc_idlist_find_client_by_nickname from the server.
5042 Not needed anymore. Affected files silcd/idlist.[ch].
5044 * Implemented the CHANNEL_CHANGE notify type handling to the
5045 server. Affected file silcd/server.c.
5049 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Added silc_server_send_notify_invite to send the INVITE
5052 notify between routers.
5054 * Implemented the INVITE command correctly to the server.
5056 * Implemented the INVITE notify type handling in the server.
5058 * Implemented the INVITE command to the client library and on the
5061 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5063 * Added function silc_server_get_client_resolve to find the
5064 client entry by ID from all ID lists and then resolve it
5065 (using WHOIS) if it cannot be found. Affected file is
5068 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Implemented the BAN command to the client library.
5072 * The JOIN command in the server now checks the invite list
5075 * Changed the silc_command_reply_payload_encode_va and the
5076 silc_command_payload_encode_va to support that if argument is
5077 NULL it ignores and checks the next argument. Affected file
5078 lib/silccore/silccommand.c.
5080 * Added silc_server_send_notify_ban to send the BAN notify
5081 type between routers.
5083 * Chaned the silc_notify_payload_encode to support that if
5084 argument is NULL it ignores and checks the next argument.
5085 Affected file lib/silccore/silcnotify.c.
5087 * Tested ban lists in router environment successfully.
5089 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5091 * Implemented BAN command to the server, in silcd/command.[ch].
5093 * Removed the BAN and INVITE_LIST modes from the CMODE command
5096 * Added function silc_string_match to regex match two strings.
5097 Affected files lib/silcutil/silcutil.[ch].
5099 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5101 * Redefined parts of the SilcChannelEntry in the server to support
5102 the new ban and invite lists.
5104 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Redefined the INVITE command. The same command can be used to
5107 invite individuals to the channel but also to manage the invite
5108 list of the channel (to add to and remove from the invite list).
5109 Updated the protocol specs.
5111 * Added new command SILC_COMMAND_BAN that can be used to manage
5112 the ban list of the channel. Updated the protocol specs.
5114 * Removed the channel modes: the SILC_CMODE_BAN and the
5115 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5116 in the CMODE command. The equivalent features are now available
5117 using INVITE and BAN commands. Updated the protocol specs.
5119 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5120 in the network about change in the current ban list. The notify
5121 type is not used by the client.
5123 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5124 support the invite lists.
5126 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Added new function silc_string_regexify that converts string
5129 including wildcard characters into regex string that can
5130 be used by the GNU regex library. Added into the file
5131 lib/silcutil/silcutil.[ch].
5133 Added silc_string_regex_combine to combine to regex strings
5134 into one so that they can be used as one regex string by
5135 the GNU regex library. Added into the file
5136 lib/silcutil/silcutil.[ch].
5138 Added silc_string_regex_match to match two strings. It returns
5139 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5141 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5143 * Imported GNU regex to the soruce tree into lib/contrib.
5144 Fixed some compiler warning from the regex.c.
5146 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Fixed MOTD command in the server to work in router environment.
5150 * Fixed the MOTD command in the client library to support
5151 the server argument in the command.
5153 * Added `nickname_len' argument to the silc_idlist_add_client
5154 in the server, as the `nickname' argument may be binary data
5157 * Added silc_idlist_get_channels to return all channels from
5160 * Implemented LIST command to the server. Affected file is
5163 * Implemented the LIST command to the client library and on the
5166 * Added [<user count>] argument to the LIST command reply.
5167 With private channels the user count is not shown.
5169 * Updated TODO and README.
5171 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5173 * The client entry's data.registered must be TRUE even with
5174 global client entry on global client list. The data.registered
5175 is used to check whether the client is anymore in the network,
5176 for example with WHOWAS command so it must be valid.
5178 * Fixed the WHOWAS command in the server. It now actually works
5179 in router environment. Added function into silcd/command_reply.c
5180 silc_server_command_reply_whowas_save.
5182 * Added silc_idlist_purge function to the silcd/idlist.c
5183 to periodically purge the ID Cache.
5185 * Fixed INFO command in the server. It works now in router
5186 environment. Added <server name> argument to the INFO command
5187 reply. Updated the protocol specs.
5189 * Fixed minor bug in silc_idcache_purge to not purge if the
5190 expire value is zero.
5192 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5193 they were buggy because of the WHOWAS information.
5195 * Fixed local command MSG to handle the async resolving of
5196 the remote client properly. It used to fail the first MSG.
5197 Affected file silc/local_command.c.
5199 * Added `data_len' field to SilcIDCache context.
5201 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5203 * Update TODO. Todo in commands in the server.
5205 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5208 used by routers as broadcast packet to inform other routers
5209 about the changed user mode.
5211 Implemented the notify handling in the server. Affected file is
5212 silcd/packet_receive.c. Added the function
5213 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5215 * Added new generic Channel Payload and deprecated the New Channel
5216 Payload. The New Channel Payload is now the generic Channel
5219 * Added new argument `mode' to the silc_server_send_new_channel
5220 as it is required in the Channel Payload now.
5222 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5223 and created a new and real SilChannelPayload to represent the
5224 new generic Channel Payload. Implemented the encode/decode
5225 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5227 * Added silc_server_get_client_channel_list to return the list
5228 of channels the client has joined for WHOIS command reply.
5229 Affected file silcd/server.[ch].
5231 * Implemented the channel list sending in the WHOIS command reply
5232 in server and in the client.
5234 Implemented the channel list displaying on the user interface
5235 as well. Affected file silc/client_ops.c.
5237 * Added silc_channel_payload_parse_list to parse list of Channel
5238 Payloads. It returns SilcDList list of SilcChannelPayloads.
5239 Client for example can use this function to parse the list of
5240 channels it receives in the WHOIS command reply. The caller
5241 must free the list by calling silc_channel_payload_list_free.
5242 Affected files lib/silccore/silcchannel.[ch].
5244 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5246 * Added one new argument <user mode> to the WHOIS command reply
5247 to return the mode of the user in SILC. Updated the protocol
5250 Implemented it to the server and client.
5252 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5254 * Fixed the mode printing on the user interface on joining.
5255 Affected file silc/client_ops.c.
5257 * Implemented the UMODE command and user modes in general to the
5258 client library and to the user interface.
5260 * Implemented the UMODE command to the server.
5262 * The server now sends UNKNOWN_COMMAND error status if client sends
5263 unknown command. Affected file silcd/command.c.
5265 * All server commands now handle the command identifier the right
5266 way when sending the command reply to the client. The client can
5267 use to identify the command replies with the identifier.
5269 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5271 * Added silc_server_get_client_route to resolve the route to
5272 the client indicated by the client ID. Affected file is
5275 * Added silc_server_relay_packet as general function to relay
5276 packet to arbitrary destination. This deprecates functions
5277 like _send_private_message_key, _relay_notify etc. Affected
5278 file is silcd/packet_send.[ch].
5280 Removed silc_server_send_key_agreement,
5281 silc_server_send_private_message_key and
5282 silc_server_packet_relay_notify functions from the file
5283 silcd/packet_send.[ch].
5287 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5288 server. Affected file silcd/packet_receive.[ch].
5290 * Implemented the KILL command to the client. Implemented the
5291 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5292 Affected files lib/silcclient/command[_reply].c and
5293 lib/silcclient/client_notify.c. Implemented the KILL notify
5294 printing in the user inteface.
5296 * Fixed a lot silc_parse_nick memory leaks from the client
5297 library in the file lib/silcclient/command.c.
5299 * Changed the silc_server_send_notify_on_channels's `sender'
5300 argument from SilcSocketConnection to SilcClientEntry to
5301 check the sender as entry and not as connection object and not
5302 to send to the client provided as argument. The affected file
5303 is silcd/packet_send.[ch].
5305 * The notify packets that are destined directly to the client used
5306 to not to be processed by the server. Now changed that and the
5307 server processes all notify packets. After relaying the packet
5308 to the client the notify packet is processed in the server.
5310 * The silc_server_free_client_data now checks whether there is
5311 pending outgoing traffic for the client and purges the data to
5312 the network before removing the client entry.
5314 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5316 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5317 an client is killed from the SILC Network. Updated the protocol
5320 Added new function silc_server_send_notify_killed to the
5321 silcd/packet_send.[ch].
5323 * Added function silc_server_packet_relay_notify to relay notify
5324 packets that are destined directly to a client. In this case
5325 the server does not process the notify packets but merely relays
5326 it to the client. Affected file silcd/packet_send.[ch].
5328 Added also silc_server_packet_process_relay_notify to check
5329 whereto relay the notify. Affected file is
5330 silcd/packet_receive.[ch].
5332 * Implemented the KILL command to the server.
5336 * Added the backup schema desgined last fall to the protocol
5337 specs for everyone to see. The specification is in the
5338 *-spec-xx.txt draft and the packet type definitions for the
5339 backup routers is in *-pp-xx.txt draft. Thusly, added also
5340 new packet type SILC_PACKET_CELL_ROUTERS.
5342 * A big security problem in the implementation discovered. The
5343 signoff of an client did not cause new channel key generation
5344 which it of course should've done. The channel keys must be
5345 always re-generated when client leaves (or signoffs) the channel.
5346 The silc_server_remove_from_channels funtion now handles
5347 the channel key re-generation.
5349 * Added `sender' argument to the silc_server_send_notify_on_channels
5350 to not to send the client provided as argument. Affected file
5351 silcd/packet_send.[ch].
5353 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Implemented OPER and SILCOPER commands into the server and
5358 * Added silc_auth_verify and silc_auth_verify_data to verify
5359 the authentication directly from the authentication payload.
5360 It supports verifying both passphrase and public key based
5361 authentication. Affected file lib/silccore/silcauth.[ch].
5363 * Added `hash' field to the SilcIDListData structure. It is the
5364 hash negotiated in the SKE protocol. Affected file is
5367 * Slight redesigning of the SilcAuthPayload handling routines.
5368 Do not send SilcPKCS but SilcPublicKey as argument.
5370 * Implemented the public key authentication support to the
5371 serverconfig. The public key is loaded from the provided path
5372 and saved as authentication data to void * pointer. Thus,
5373 changed the unsigned char *auth_data to void *auth_data;
5375 * Fixed SHUTDOWN command to send the reply before the server
5376 is shutdown. :) Affected file silcd/command.c.
5378 * Fixed fatal bug in CONNECT command. The hostname was invalid
5379 memory and server crashed. Affected file silcd/command.c.
5381 * Fixed fatal bug in CLOSE command. The server_entry became
5382 invalid but was referenced later in the command. Affected file
5385 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5387 * Fixed fatal bug in failure packet handling. Server ignored
5388 the failure and thus crashed when it came.
5392 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5395 that the command may be executed only once in (about) 2 seconds.
5396 The old SILC_CF_LAG flag is same but allows command bursts up
5397 to five before limiting.
5399 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5400 server code. Various commands now includes the CF_LAG_STRICT
5401 flag to disallow any kind of miss-use of the command.
5403 * Fixed the silc_buffer_unformat to not to allocate any data
5404 if the length of the data is zero. It used to allocate the
5405 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5407 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5409 * Changed the format of AdminConnection configuration section
5410 in the server. Added username of the admin to the format.
5411 Affected files silcd/serverconfig.[ch].
5413 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5414 to return admin configuration data by host, username and/or
5417 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5419 * Implemented WHOWAS command to the server. Added the functions:
5421 silc_server_command_whowas_parse,
5422 silc_server_command_whowas_send_reply,
5423 silc_server_command_whowas_from_client and
5424 silc_server_command_whowas_from_server
5426 * Added <Client ID> argument to the WHOWAS command reply. Updated
5427 the protocol specs accordingly.
5429 * Implemented WHOWAS command and command_reply to the client
5432 Implemented the WHOWAS printing on the user interface.
5434 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5436 * Added new argument to the WHOWAS command reply, the real name.
5437 It is an optional argument. Updated the protocol specs.
5439 * Added SilcIDCacheDestructor callback that is registered when
5440 the SilcIDCache is allocated. The callback is called when
5441 an cache entry in the ID Cache expires, or is purged from the
5442 cache. Added into lib/silccore/idcache.[ch].
5444 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5445 to destruct the client entries when the cache entry expires.
5446 Other ID Cache's in server and in the client library ignores
5449 * If the ID Cache entry's `expire' field is zero then the entry
5450 never expires. Added boolean `expire' argument to the
5451 silc_idcache_add function in the lib/silccore/idcache.[ch].
5452 If it is TRUE the default expiry value is used.
5454 * Added silc_server_free_client_data_timeout that is registered
5455 when client disconnects. By default for 5 minutes we preserve
5456 the client entry for history - for WHOWAS command.
5458 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5460 * Added support to the server to enforce that commands are not
5461 executed more than once in 2 seconds. If server receives
5462 commands from client more frequently, timeout is registered
5463 to process the commands. Affected file silcd/command.c.
5464 Added new function silc_server_command_process_timeout.
5466 * Changed NICK_NOTIFY handling in client library to check that
5467 if the client's nickname was changed, so there is no need to
5468 resolve anything from the server.
5470 * Removed error printing from the WHOIS and IDENTIFY commands.
5471 If error occurs then it is ignored silently in the client library.
5472 The application, however, may map the received error to
5473 human readable error string. The application currently maps
5474 the NO_SUCH_NICKNAME error to string.
5476 * Made the command status message public to the application. Moved
5477 them from lib/silcclient/command_reply.c to
5478 lib/silcclient/command_reply.h. The application can map the
5479 received command status to the string with the
5480 silc_client_command_status_message function.
5482 * Added check to the server to check that client's ID is same
5483 as the Source ID in the packet the client sent. They must
5486 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5488 * Added dist-bzip hook to the Makefile.am to make bzip2
5489 compressed distributions.
5491 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5493 * Server now enforces the maximum length for the nickname and
5494 the channel as protocol specification dictates. 128 bytes for
5495 nickname and 256 bytes for channel name.
5497 * Moved the WHOIS printing to the application. The client libary
5498 does not print out the WHOIS information anymore, the application
5499 must do it. Renamed silc_client_command_reply_whois_print to
5500 the silc_client_command_reply_whois_save.
5502 The client's idle time is also sent to the application now, and
5503 the idle is shown on screen.
5505 * Added silc_client_command_reply_identify_save to save the
5506 received IDENTIFY entries.
5508 * Do not check for channel private keys in message sending and
5509 reception if the channel does not have the PRIVKEY mode set.
5510 Affected file lib/silclient/client_channel.c.
5512 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5514 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5515 just surfaced after chaning the JOIN procedure.
5517 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5519 * Added silc_client_get_clients_by_list to get client entries
5520 from Client ID list, that is returned for example by JOIN
5521 and USERS command replies. The application should use this
5522 function for example when JOIN command reply is received to
5523 resolve the clients already on the channel (library does not
5524 do that anymore as USERS command reply is not used in the JOIN
5525 procedure anymore). Affected files lib/silcclient/silcapi.h and
5526 lib/silcclient/idlist.c.
5528 * JOIN command reply and USERS command reply returns now SilcBuffer
5529 pointers instead of unsigned char pointers when returning
5530 the client list and mode list.
5532 * Added <Client ID> argument to the JOIN command reply, mainly
5533 for the server to identify for which client the command was
5534 originally sent. Updated protocol specs accordingly.
5536 * Added SilcDlist private_key pointer to the SilcChannelEntry
5537 in the client to support the channel private keys. Affected
5538 file is lib/silcclient/idlist.h.
5540 * Added SilcChannelPrivateKey argument to the function
5541 silc_client_send_channel_message so that application can choose
5542 to use specific private ke if it wants to. If it is not provided,
5543 the normal channel key is used, unless private keys are set.
5544 In this case the first (key that was added first) is used
5545 as the encryption key.
5547 * Implemented the support for channel private key handling.
5548 Implemented the following functions:
5550 silc_client_add_channel_private_key,
5551 silc_client_del_channel_private_keys,
5552 silc_client_del_channel_private_key,
5553 silc_client_list_channel_private_keys and
5554 silc_client_free_channel_private_keys
5556 Affected file lib/silcclient/client_channel.c.
5558 * Added the support for the private keys in the channel message
5559 sending and encryption and in the message reception and
5560 decryption. Affected funtions are
5561 silc_client_send_channel_message and silc_client_channel_message.
5563 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5565 * Added SKE's key verify callback to the client library's
5566 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5568 * Removed the statement that server (or router) must send USERS
5569 command reply when joining to the channel so that the client
5570 knows who are on the channel. Instead, the client list and
5571 client's mode list is now sent in the JOIN command reply to the
5572 client who joined channel. This is better solution.
5574 * Added function silc_server_get_users_on_channel and function
5575 silc_server_save_users_on_channel to the silcd/server.[ch].
5577 * Removed function silc_server_command_send_users from the
5580 * Do not show topic on the client library anymore. The topic is
5581 sent in the command reply notify to the application and the
5582 application must show the topic now.
5584 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5586 * Added client searching by nickname hash into the IDENTIFY and
5587 WHOIS commands in the server as they were clearly missing from
5588 them. Affected file is silcd/command.c.
5590 * Fixed a bug in private message receiving in the client library.
5591 The remote ID was freed and it wasn't supposed, now it is
5594 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5596 * Minor fix to the channel payload; allocate the data area, as it
5597 needs to be of specific length.
5599 * If the key agreement port is zero then the operating
5600 system will define the bound port. Affected files are
5601 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5603 * Added new function silc_channel_payload_decrypt into the file
5604 lib/silccore/silcchannel.[ch].
5606 * Moved the channel message etc, check from silc_packet_decrypt
5607 to applications. The library calls now a generic
5608 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5609 when the packet is either normal or special. This was done to
5610 allow more wide range of checking that was not allowed when
5611 the code was in library. Now applications can do virtually any
5612 checks to the packet and return to the library the decision how
5613 the packet should be processed. Affected files are
5614 lib/silccore/silcpacket.[ch].
5616 Added silc_server_packet_decrypt_check to the server and
5617 silc_client_packet_decrypt_check to the client library.
5619 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5620 to send with specified source and destination information.
5622 * Channel message delivery between routers was broken after the
5623 channel key distribution was fixed earlier. The channel key
5624 was used be to distributed to other routers as well which is not
5625 allowed by the protocol. Now this is fixed and channel keys
5626 really are cell specific and the channel message delivery between
5627 routers comply with the protocol specification.
5629 * Fixed various commands in server to check also the global list
5630 for the channel entry and not just the local list. The affected
5631 file silcd/command.c.
5633 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Added assert()s to buffer formatting and unformatting routines
5636 to assert (if --enable-debug) when error occurs. Affected
5637 file: lib/silcutil/silcbuffmt.c.
5639 * Changed to auto-reconnect to check whether the remote host is
5640 router and register the re-connect timeout if it is. It used
5641 to check that whether we are normal server, but router must do
5642 auto-reconnect with another router as well. Affected file
5645 * Removed the [<key len>] option from CMODE command as the cipher
5646 name decides the key length, nowadays. See the defined ciphers
5647 from the protocol specification.
5649 * Added [<hmac>] option to the CMODE command to define the HMAC
5650 for the channel. Added SILC_CMODE_HMAC channel mode.
5652 * Added [<hmac>] option for the JOIN command so that user can
5653 select which HMAC is used to compute the MACs of the channel
5656 * Added Hmac field to the Channel Message Payload. The integrity
5657 of plaintext channel messages are now protected by computing
5658 MAC of the message and attaching the MAC to the payload. The
5659 MAC is encrypted. Now, it is clear that this causes some
5660 overhead to the size of the packet but rationale for this is that
5661 now the receiver can verify whether the channel message decrypted
5662 correctly and also when private keys are set for the channel the
5663 receiver can decrypt the packet with several keys and check from
5664 the MAC which key decrypted the message correctly.
5666 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5667 lib/silccrypt/silccipher.[ch].
5669 * Added silc_hash_len to return the digest length into the
5670 lib/silcrypt/silchash.[ch].
5672 * Rewrote parts of Silc Channel Payload interface in the
5673 lib/silccore/silcchannel.[ch]. The encode function now also
5674 encrypts the packet and parse function decrypts it.
5676 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5678 * Fixed a minor formatting bug in the SKE's key material processing.
5679 It actually might have processed the keys wrong way resulting
5682 * Redefined the mandatory HMAC algorithms and added new algorithms.
5683 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5684 and hmac-md5 truncated to 96 bits. The mandatory is now
5685 hmac-sha1-96. Rest are optional (including the one that used
5686 to be mandatory). Rationale for this is that the truncated HMAC
5687 length is sufficient from security point of view and can actually
5688 make the attack against the HMAC harder. Also, the truncated
5689 HMAC causes less overhead to the packets. See the RFC2104 for
5692 * Added new [hmac] configuration section. The SKE used to use
5693 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5694 is of course wrong. The official names that must be proposed in
5695 the SKE are the ones defined in the protocol specification
5696 (hmac-sha1-96 for example). The user can configure any hmac
5697 using any hash function configured in the [hash] section. At
5698 least, the mandatory must be configured.
5700 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5702 * Added HMAC list to the SKE proposal list. It has now both
5703 hash algorithm list and HMAC list. This makes the protocol
5704 incompatible with previous versions. The SKE now seems to work
5705 the way it is supposed to work, for the first time actually.
5707 * Defined plain Hash algorithms to the protocol specification.
5710 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5712 * Implemented support for key agreement packets into the server.
5713 Added functions silc_server_key_agreement and
5714 silc_server_send_key_agreement. Other than these functions,
5715 server has nothing to do with this packet.
5717 * Added support for private message key packets into the server.
5718 Added functions silc_server_private_message_key and
5719 silc_server_send_private_message_key.
5723 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5724 called in the protocol's final callback instead in the END
5725 protocol state. This makes a little more sense and in the same
5726 time in client we can use the same protocol routines for normal
5727 key exchange and to key agreement packet handling as well.
5729 * Added to both client's and server's KE protocol context the
5730 SilcSKEKeyMaterial pointer to save the key material. We will
5731 bring the key material to the protocol's final callback by doing
5732 this. The final callback must free the key material.
5734 * Added SKE's packet_send callback into client's KE protocol
5735 context so that the caller can choose what packet sending function
5736 is used. This way we can use different packet sending when
5737 doing normal SKE when doing key agreement packet handling (in
5738 the key agreement packet handling we do not want to encrypt
5741 * Implemented the responder side of the key agreement routines
5742 in the client. The client can now bind to specified port and
5743 accept incoming key negotiation. The key material is passed
5744 to the application after the protocol is over.
5746 * Implemented the processing of incoming Key Agreement packet
5747 in the client. Added function silc_client_key_agreement to
5750 * Implemented the intiator side of the key agreement routines
5751 in the client. The client can now initiate key agreement with
5752 another remote client. The key material is passed to the
5753 application after the protocol is over.
5755 * Created client_keyagr.c to include all the key agreement
5758 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5759 SILC_TASK_CALLBACK except that it is not static.
5761 * Created client_notify.c and moved the Notify packet handling
5762 from the client.[ch] into that file.
5764 * Created client_prvmsg.c and moved all private message and
5765 private message key routines from the client.[ch] into that file.
5767 * Create client_channel.c and moved all channel message and
5768 channel private key routines from the client.[ch] into that file.
5770 * Changed silc_client_get_client_by_id_resolve to resolve with
5771 WHOIS command instead of IDENTIFY command, in the file
5772 lib/silclient/idlist.c.
5774 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5776 * Implemented the SKE's responder side to the Client library.
5778 * When FAILURE is received to the protocol do not trust it
5779 blindly. Register a timeout to wait whether the remote closes
5780 the connection as it should do it, only after that process the
5781 actual failure. This was changed to both client and server.
5783 * Added client_internal.h to include some of the structures
5784 there instead of client.h in lib/silcclient/.
5786 * Added function silc_task_unregister_by_callback to unregister
5787 timeouts by the callback function.
5789 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5791 * Some "Incomplete WHOIS info" errors has been appearing on the
5792 log files. Took away the entry->userinfo check from WHOIS
5793 reply sending. The entry->userinfo is now " " if client did not
5794 provide one. I thought this was fixed earlier but something
5795 is wrong still. Let's see if the error still appears.
5797 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5799 * Fixed a minor bug in the login when the channel key is
5800 re-generated in the server. It used to generate the key in
5801 wrong order and thus caused problems in the channel traffic.
5803 * Fixed a minor bug in channel key distsribution after
5804 KICK command. The key was not sent to the router even though
5807 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5809 * Added silc_ske_process_key_material_data as generic routine
5810 to process any key material as the SILC protocol dictates. The
5811 function is used by the actual SKE library but can be used by
5812 applications as well. This relates to the private message keys
5813 and the channel private keys since they must be processed the
5814 same way the normal SILC session keys. The protocol dictates
5815 this. Affected files: lib/silcske/silcske.[ch].
5817 Added also silc_ske_free_key_material to free the
5818 SilcSKEKeyMaterial structure.
5820 * Defined silc_cipher_set_key function to set the key for
5821 cipher without using the object's method function. The affected
5822 files: lib/silccrypt/silccipher.[ch].
5824 * Implemented silc silc_client_add_private_message_key,
5825 silc_client_add_private_message_key_ske,
5826 silc_client_del_private_message_key,
5827 silc_client_list_private_message_keys and
5828 silc_client_free_private_message_keys functions in the
5831 Added functions silc_client_send_private_message_key to send
5832 the Private Message Key payload and silc_client_private_message_key
5833 to handle incoming Private Message Key payload.
5835 * Added Cipher field to the Private Message Key payload to set
5836 the cipher to be used. If ignored, the default cipher defined
5837 in the SILC protocol (aes-256-cbc) is used.
5839 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5841 * Removed lib/silcclient/ops.h file.
5843 Redefined parts of the SILC Client Library API. Created new
5844 file silcapi.h that deprecates the ops.h file and defines the
5845 published Client Library API. Defined also private message key
5846 API and channel private key API into the file.
5848 This is the file that the application must include from the
5849 SILC Client Library. Other files need not be included by
5850 the application anymore.
5852 * Added new key_agreement client operation callback and also
5853 defined the Key Agreement library API for the application.
5855 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5858 is used by clients to request key negotiation between another
5859 client in the SILC network. If the negotiation is started it
5860 is performed using the SKE protocol. The result of the
5861 negotiation, the secret key material, can be used for example
5862 as private message key.
5864 Implemented the Key Agreement payload into the files
5865 lib/silccore/silauth.[ch].
5867 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5869 * Redefined ciphers for the SILC protocol. Added some new ciphers
5870 and defined the key lengths for the algorithms. Changed the
5871 code accordingly. The default key length is now 256 bits.
5873 * Fixed SKE key distribution function silc_ske_process_key_material
5874 when the key length is more than 128 bits. The default key
5875 length in SILC is now 256 bits.
5877 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5878 to indicate unsupported algorithm.
5880 * Renamed rijndael.c to aes.c and all functions as well.
5882 * Fixed a long standing channel key setting bug in client library.
5883 Weird that it has never surfaced before.
5885 * Fixed bug in channel deletion. If the entire channel is removed
5886 then it must also delete the references of the channel entry
5887 from the client's channel list as the client's channel entry and
5888 the channel's client entry share same memory.
5890 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5892 * Implemented CONNECT and SHUTDOWN commands in the client.
5894 * Implemented CLOSE command to the client.
5896 * Added the function silc_idlist_find_server_by_name into the
5897 files silcd/idlist.[ch].
5899 Added the function silc_idlist_find_server_by_conn into the
5900 files silcd/idlist.[ch].
5902 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5904 * DIE command was renamed to SHUTDOWN. Updated the both code
5907 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5908 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5910 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5913 * Added function silc_server_create_connection function to create
5914 connection to remote router. My server implementation actually
5915 does not allow router to connect to normal server (it expects
5916 that normal server always initiates the connection to the router)
5917 so the CONNECT command is only good for connecting to another
5920 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5922 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5923 or some other client was kicked from the channel.
5925 Implemented the handling of the notify type to both client
5928 Implemented silc_server_send_notify_kicked to send the KICKED
5929 notify. It is used to send it to the server's primary router.
5931 * Implemented the KICK command into server and client.
5933 * Added `query' argument to the silc_idlist_get_client function
5934 to indicate whether to query the client from server or not if
5937 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5938 to indicate that the client is not channel founder.
5942 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Removed the rng context from SilcPacketContext structure and
5945 changed that the packet routine uses the Global RNG API.
5947 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Added support for quit message that client can "leave" on the
5950 channel when it quits the SILC. It is ditributed inside the
5951 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5953 Added silc_server_free_client_data that will take the
5954 signoff message as argument.
5956 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5958 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Updated parts of the protocol specification to keep it up
5963 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5965 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5966 payloads in one packet.
5968 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5969 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5970 use now the new List flag.
5972 * Also deprecated the following packet types: REPLACE_ID,
5973 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5975 * Added list support for Notify packet in server.
5977 * Added silc_server_send_notify_channel_change to send the
5978 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5979 the silc_server_send_replace_id.
5981 * Added silc_server_send_notify_nick_change to send the
5982 NICK_CHANGE notify type. Deprecates the function
5983 silc_server_send_replace_id.
5985 * Added silc_server_send_notify_join to send the JOIN notify type.
5986 Deprecates the function silc_server_send_new_channel_user.
5988 * Added silc_server_send_notify_leave to send LEAVE notify type.
5989 Deprecates the function silc_server_send_remove_channel_user.
5991 * Added silc_server_send_notify_cmode and
5992 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5993 types. Deprecates the silc_server_send_set_mode function.
5995 * Added SERVER_SIGNOFF notify type to indicate that server has
5996 quit. This means that all clients on the channel from that
5997 server will drop. This can be also used when netsplit happens.
5999 Deprecated REMOVE_ID packet type since it is not needed anymore
6002 Added silc_server_send_notify_server_signoff to send the
6003 SERVER_SIGNOFF notify type. Deprecates the function
6004 silc_server_send_remove_id.
6006 Added also silc_server_send_notify_signoff to send the
6007 SIGNOFF notify type.
6009 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6010 SILC protocol from this day on. Changed the protocol
6011 specification as well.
6013 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6014 notify type. It is used between routers to notify about
6015 topic changes on a channel.
6017 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6020 * Partly updated the protocol specification to comply with the
6021 changes now made. It is still though a bit outdated.
6023 * The JOIN notify type now takes one extra argument <Channel ID>.
6024 The packet used to be destined to the channel but now the
6025 JOIN type may be sent as list thus it is impossible to
6026 destine it to any specific channel. By adding this argument
6027 it is again possible.
6029 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6031 * Added CREDITS file. The CHANGES and CREDITS file will appear
6032 in the distribution as well.
6034 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6036 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6037 types in the server's silcd/packet_receive.c.
6039 * Implemented CMODE and CUMODE to work in router environment.
6041 * Fixed minor encoding and decoding buglet from the
6042 lib/silccore/silcmode.c.
6044 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6047 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6049 * Changed all SilcConfigServer* and silc_config_server* to
6050 SilcServerConfig* and silc_server_config*, respectively.
6053 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6055 * Associated the ID (client or server ID) to the Authentication
6056 Payload to avoid any possibility of forging. Updated the
6057 protocol specification and the code accordingly.
6059 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6061 * The RSA key length is now save to the RsaKey context in the
6062 key generation process in lib/silccrypt/rsa.c. The key length
6063 is now used to figure out the maximum size of the block allowed
6064 to be encrypted/signed.
6066 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6067 is equivalent to the silc_mp_mp2bin but does not allocate any
6070 * Changed silc_mp_mp2bin API to take length argument. If it is
6071 non-zero then the buffer is allocated that large. If zero, then
6072 the size is approximated using silc_mp_sizeinbase, which however
6075 * Created Global RNG API which is global RNG that application can
6076 initialize. After initializing, any routine anywhere in the
6077 code (including library) can use RNG without allocating a new
6078 RNG object. This was done to allow this sort of use of the
6079 RNG in code that has no chance to allocate RNG object. All
6080 applications currently allocate this and many routines in the
6081 library use this. Affected file lib/silccrypt/silcrng.[ch].
6083 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6084 it to use the Global RNG API.
6086 * Defined Authentication Payload into protocol specification that
6087 is used during SILC session to authenticate entities. It is
6088 used for example by client to authenticate itself to the server
6089 to obtain server operator privileges.
6091 Implemented this payload into the lib/silccore/silcauth.[ch].
6092 Implemented also routines for public key based authentication
6093 as the new protocol specification dictates.
6095 Moved definitions of different authentication methods from
6096 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6098 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6099 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6100 silc_pkcs_verify_with_hash functions into the file
6101 lib/silccrypt/silcpkcs.[ch].
6103 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6105 * The client entry's userinfo pointer must be always valid.
6106 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6107 will fail since it requires the userinfo. Now, the userinfo
6108 is allocated as "" if actual userinfo does not exist. Actually,
6109 it must exist and it is totally Ok to drop client connections
6110 that does not announce the userinfo. However, we will make
6111 this workaround for now.
6113 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6114 to return the remote port by socket.
6116 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6118 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6119 SILC_SERVER_PENDING_EXEC and added an new macro
6120 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6121 data or when error occurs while processing the pending command.
6123 Added new argument `destructor' into silc_server_command_pending
6124 and to the SilcServerCommandPending object. This destructor is
6125 now called after calling the pending callback or if error occurs
6126 immediately. If error occurs the actual pending callback won't
6127 be called at all - only the destructor. The destructor may be
6128 NULL if destructor is not needed.
6130 All this applies for client library code as well. Similar
6131 changes were made there as well for the pending commands.
6133 In the client, the application must now allocate the
6134 SilcClientCommandContext with the silc_client_command_alloc
6137 * Added reference counter to the SilcServerCommandContext. Added
6138 function silc_server_command_alloc and silc_server_command_dup
6141 Same type of functions added to the client library for the same
6144 * Removed the cmd_ident from IDListData away since it is now
6145 global for all connections. It is the command identifier used
6146 in command sending and with pending commands. The affected file
6149 * Added reference counter to the SilcSocketConnection objecet to
6150 indicate the usage count of the object. The object won't be
6151 freed untill the reference counter hits zero. Currently only
6152 server uses this, and client ignores it. The client must be
6153 set to use this too later. The affected files are
6154 lib/silccore/silcsockconn.[ch]. Added also the function
6155 silc_socket_dup to increase the reference counter.
6157 This was mainly added because it is possible that the socket
6158 is removed underneath of pending command or other async
6159 operation. Now it won't be free'd and proper DISCONNECTING
6160 flags, etc. can be set to avoid sending data to connection that
6161 is not valid anymore.
6163 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6164 the connection. After that it sets SILC_SET_DISCONNECTED.
6165 It is, however, possible that the socket data is not still freed.
6166 The silc_server_packet_process now checks that data is not
6167 read or written to connection that is DISCONNECTED. The socket
6168 get's freed when the reference counter hits zero.
6170 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6172 * Changed the client operation API: channel_message operation's
6173 `sender' is now the client entry of the sender, not the nickname
6174 and the `channel' is the channel entry, not the channel name.
6176 In the private_message operation the `sender' is now also the
6177 client entry of the sender not the nickname.
6179 Affected file is lib/silcclient/ops.h and all applications
6180 using the client operations.
6182 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6184 * Moved the calling of ops->connect() from connect_to_server_final
6185 into receive_new_id functin since that is the point when the
6186 client is actually allowed to send traffic to network. The
6187 affected file is lib/silcclient/client.c.
6189 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6191 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6192 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6193 (if needs broadcasting) instead of broadcasting the packets one
6194 by one which would make a burst in the network traffic.
6196 * Added `broadcast' argument to the functions in silcd/server.[ch]
6197 silc_server_create_new_channel[_with_id] to indicate whether
6198 to send New Channel packet to primary router.
6200 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6202 * Added new function into the silcd/server.[ch] files:
6203 silc_server_create_new_channel_with_id to create new channel with
6204 already existing Channel ID.
6206 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6207 lib/silccore/silcpacket.h. This packet is used t send list of
6208 Set Mode payloads inside one packet. Server uses this to set
6209 the modes for the channels and clients on those channels, that it
6210 announced to the router when it connected to it. The protocol
6211 specification has been updated accordingly.
6213 * The silc_server_new_channel did not handle the packet coming
6214 from normal server as it normally does not send that. However,
6215 when it announces its channels it does send it. Implemented
6216 the support for that.
6218 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6219 into the file lib/silccore/id.h.
6221 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6223 * Fixed memory leaks in the functions silc_idlist_del_client,
6224 silc_idlist_del_channel and silc_idlist_del_server in the file
6225 silcd/idlist.c. All of those leaked like a sieve.
6227 * Fixed some small memory leaks in the client's function
6228 silc_client_notify_by_server.
6230 * Added functions into silcd/server.c: silc_server_announce_clients,
6231 silc_server_announce_channels and silc_server_announce_server.
6232 These functions are used by normal and router server to announce
6233 to its primary router about clients, channels and servers (when
6234 router) that we own. This is done after we've connected to the
6237 These functions effectively implements the following packet types:
6238 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6239 and SILC_PACKET_NEW_ID_LIST.
6241 * Added new functions into the silcd/packet_receive.[ch]:
6242 silc_server_new_id_list, silc_server_new_channel_list and
6243 silc_server_new_channel_user_list to handle the incoming
6244 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6246 * Added support of changing Channel ID in the function
6247 silc_server_replace_id. If the server that announces a channel
6248 to the router already exists in the router (with same name but
6249 with different Channel ID), router is responsible to send
6250 Replace ID packet to the server and force the server to change
6251 the Channel ID to the one router has.
6253 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6254 client that the Channel ID has been changed by the router. The
6255 normal server sends this to the client. Client must start using
6256 the new Channel ID as the channel's ID.
6258 Implemented handling of this new type into lib/silcclient/client.c
6259 into the function silc_client_notify_by_server.
6261 * Added new function silc_idlist_replace_channel_id into the files
6262 silcd/idlist.[ch] to replace the Channel ID.
6264 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6266 * Call silc_server_command_identify_check always when processing
6267 the IDENTIFY command in silcd/command.c
6269 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6271 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6272 send keepalive packets. The packet can be sent by clients,
6273 servers and routers.
6275 Added function silc_socket_set_heartbeat into the file
6276 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6277 If not set, the heartbeat is not performed. The actual
6278 heartbeat is implemented in the low level socket connection
6279 library. However, application is responsible of actually
6282 Added silc_server_send_heartbeat to send the actual heartbeat
6283 packet into silcd/packet_send.[ch]. Server now performs
6284 keepalive with all connections.
6286 * Added silc_task_get_first function into lib/silcutil/silctask.c
6287 to return the timeout task with shortest timeout. There was a bug
6288 in task unregistration that caused problems. TODO has been
6289 updated to include that task system must be rewritten.
6291 * The client library will now resolve the client information when
6292 receiving JOIN notify from server for client that we know but
6293 have incomplete information.
6295 * Rewrote parts of silc_server_remove_from_channels and
6296 silc_server_remove_from_one_channel as they did not remove the
6297 channel in some circumstances even though they should've.
6299 * Encryption problem encountered in server:
6301 The LEAVE command used to send the Channel Key packet to the
6302 router immediately after generating it. However, the code
6303 had earlier sent Remove Channel user packet but not immediately,
6304 ie. it was put to queue. The order of packets in the router
6305 was that Channel Key packet was first and Remove Channel User
6306 packet was second, even though they were encrypted in the
6307 reverse order. For this reason, MAC check failed. Now, this
6308 is fixed by not sending the Channel Key packet immediately but
6309 putting it to queue. However, this is more fundamental problem:
6310 packets that are in queue should actually not be encrypted
6311 because packets that are sent immediately gets encrypted
6312 actually with wrong IV (and thus MAC check fails). So, packets
6313 that are in queue should be encrypted when they are sent to
6314 the wire and not when they put to the queue.
6316 However, the problem is that the current system has not been
6317 designed to work that way. Instead, the packet is encrypted
6318 as soon as possible and left to the queue. The queue is then
6319 just purged into wire. There won't be any fixes for this
6320 any time soon. So, the current semantic for packet sending
6323 o If you send packet to remote host and do not force the send
6324 (the packet will be in queue) then all subsequent packets to the
6325 same remote host must also be put to the queue. Only after the
6326 queue has been purged is it safe again to force the packet
6329 o If you send all packets immediately then it safe to send
6330 any of subsequent packets through the queue, however, after
6331 the first packet is put to queue then any subsequent packets
6332 must also be put to the queue.
6334 Follow these rules and everything works fine.
6336 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6338 * Added new function silc_server_remove_clients_by_server to
6339 remove all client entries from ID list when the server connection
6340 is lost. In this case it is also important to invalidate all
6341 client entires as they hold the invalid server entry. This
6342 fixes fatal bug when server has lost connection and will reconnect
6345 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6347 * Made some sanity checks to silc_server_daemonise like to check
6348 whether the requested user and group actually exists.
6350 * Added sanity check to SKE's silc_ske_responder_finish to check
6351 that the public and private key actually is valid.
6353 * Invalidate the client's nickname when receiving Replace ID
6354 packet and the Client ID is being replaced. This means that the
6355 server will query the nickname if someone needs it (client)
6358 * Sort the ID Cache in client library when the ID Cache data
6359 has changed (needs sorting).
6361 * Do not allow for SILC client to create several connections to
6362 several servers. The client does not support windows right now
6363 and generating multiple connections causes weird behaviour.
6365 Irssi-silc client does support windows and can handle several
6366 connections without problems, see: www.irssi.org and SILC plugin.
6368 * Fixed some places where client was added to the IDList. The
6369 rule of thumb is following (in order to get everything right):
6370 If the client is directly connected local client then the
6371 `connection' argument must be set and `router' argument must be
6372 NULL to silc_idlist_add_client function. If the client is not
6373 directly connected client then the `router' argument must
6374 bet set and the `connection' argument must be NULL to the
6375 silc_idlist_add_client function.
6377 * The funtion silc_server_packet_send_local_channel actually did
6378 not check whether the client was locally connected or not. It
6379 does that now. Fixed a bug related to LEAVE command.
6381 * Fixed Remove Channel User payload parsing bug in server's
6382 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6384 * The server's silc_server_save_channel_key now checks also the
6385 global ID list for the channel as it might not be in the local
6386 list. Fixed a bug related to LEAVE command.
6388 * Is this the end of the [<unknown>] buglet that has been lurking
6389 around for a long time? A little for loop fix in server's
6390 silc_server_command_whois_parse that is used by both IDENTIFY
6391 and WHOIS command. At least, this was a clear bug and a cause
6392 of one type of [<unknown>] buglet.
6394 * WHOIS and IDENTIFY commands call the function
6395 silc_server_command_[whois/identify]_check function even if
6396 we are not router server.
6398 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * Added --with-gmp configuration option. If set the GMP
6401 is always compiled in the SILC source tree. If not set then
6402 it is checked whether the system has the GMP3 installed. If
6403 it has then the GMP won't be compiled (the system's headers
6404 and library is used), if it doesn't have it then the GMP is
6405 compiled in the SILC source tree.
6407 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6409 * Changed RSA private exponent generation to what PKCS #1
6410 suggests. We try to find the smallest possible d by doing
6411 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6412 not security fix but optimization.
6414 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6416 * Added new config entry [Identity] to fork the server and run
6417 it as specific user and group. A patch from Bostik.
6419 * Imported Dotconf configuration library into lib/dotconf.
6420 This will be used to create the SILC configuration files later.
6421 It will appear in the distsribution after this commit.
6423 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * A big code auditing weekend happening. Auditing code for
6426 obvious mistakes, bugs and errors. Also, removing any code
6429 Removed files for being obsolete:
6431 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6432 inline in the file lib/silcutil/silcbuffer.h)
6434 o lib/silcutil/silcbufutil.c (the header has inline versions)
6436 Changed code to fix possible error conditions:
6438 o The buffer formatting routines now check that the destination
6439 buffer really has enough space to add the data. This applies for
6440 both buffer formatting and unformatting
6441 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6442 unformatting was changed to accomodate following rules:
6443 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6444 sent to the function while XXX_*STRING will not allocate or copy
6445 the data into the buffer. Instead it sets the pointer from the
6446 buffer into the pointer sent as argument (XXX_*STRING used to
6447 require that the pointer must be allocated already). This change
6448 makes this whole thing a bit more consistent and more optimized
6449 (note that the data returned in the unformatting with XXX_*STRING
6450 must not be freed now). The routines return now -1 on error.
6452 o Tried to find all code that use buffer_format and buffer_unformat
6453 and added return value checking to prevent formatting and
6454 especially unformatting errors and possible subsequent fatal
6457 o Changed ske->x and ske->KEY to mallocated pointers in
6458 lib/silcske/silcske.h. Fixed possible data and memory leak.
6460 o Added return value checking to all *_parse* functions. Fixed
6461 many memory leaks as well.
6463 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6464 so that buffer overflows would not happen. All code now also
6465 checks the return value as it can fail.
6467 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6469 * Added reconnection support to server if the normal server looses
6470 its connection to the router (for example if router is rebooted).
6471 The server performs normal reconnection strategy implemented
6472 to the server. Affected file silcd/server.c.
6474 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6476 * Added new packet type SILC_PACKET_SET_MODE that is used to
6477 distribute the information about changed modes (for clients,
6478 channels and clients channel modes) to all routers in the
6479 network. Updated the protocol specification accordingly.
6481 Added functions into silcd/packet_send.c and
6482 silcd/packet_receive.c: silc_server_send_set_mode,
6483 silc_server_set_mode.
6485 Added new files silcmode.[ch] into lib/silccore that implements
6486 the encoding and decoding of Set Mode Payload. Added new type
6487 SilcSetModePayload. Moved the definitions of different modes
6488 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6490 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6492 * Oops, a little mistake in server's connection authentication
6493 protocol. The protocol is not ended with FAILURE but with
6494 SUCCESS if the authentication is Ok. :) Affected file is
6497 * Implemented NICK_CHANGE notify handling in server in the file
6498 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6499 the local clients on the channel. After the changing nickname
6500 in router environment snhould work and the [<unknown>] nickname
6501 should appear no more.
6503 The silc_server_replace_id function that receives the Replace ID
6504 payload now sends the NICK_CHANGE notify type also in the file
6505 silcd/packet_receive.c
6507 * Changed WHOIS and IDENTIFY command to support the maximum amount
6508 of arguments defined in protocol specs (3328 arguments). This
6509 fixed a bug that caused problems when there were more than three
6512 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6514 * Added extra parameter, command identifier, to the
6515 silc_client_send_command so that explicit command identifier
6518 Changed that ID list routines uses specific command identifier
6519 when sending WHOIS/IDENTIFY requests to the server so that they
6520 can be identified when the reply comes back.
6522 Affected files lib/silcclient/command.[ch],
6523 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6525 * Added `sender' argument to silc_server_packet_send_to_channel
6526 to indicaet the sender who originally sent the packet to us
6527 that we are now re-sending. Ignored if NULL. Affected file
6528 silcd/packet_send.[ch].
6530 * Added some server statistics support in silcd/server_internal.h
6531 SilcServerStatistics structure and around the server code. Also
6532 send some nice statistics information when client is connecting
6535 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6537 * Fixed channel ID decoding in server's JOIN command reply in
6538 silcd/command_reply.c
6540 * Fixed braodcasting of replace ID payload to not to send it if
6541 we are standalone server in silcd/packet_receive.c.
6543 * Fixed all channel message sending routines to not to send
6544 packets to clients that has router set, since they are routed
6545 separately in the same function earlier. Affects file
6546 silcd/packet_send.c and all channel packet sending functions.
6548 * In USERS reply, res_argv[i] are not allocated, the table
6549 is allocated. Thus changed that free the table, not its
6552 * In server's whois_check and identify_check if the client is
6553 locally connected do not send any WHOIS commands - they are not
6556 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6558 * Fixed some minor bugs in client when sending WHOIS command. The
6559 arguments was in wrong order.
6561 * Removed statis function add_to_channel from server in
6562 silcd/command.c that was previously used with the joining but
6565 * Tested USERS command in router environment successfully with two
6566 routers, two servers and two clients.
6568 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6570 * Reorganized the USERS command and command reply in client library
6571 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6572 When the command is given by user we register a pending command
6573 callback that will reprocess the command after the reply has been
6574 received from the server. When reprocessing the packet we then
6575 display the information. Thus, the USERS information is displayed
6576 now in the command callback instead of in the command reply
6577 callback. The processing of the command is same as previously
6578 when server has sent the command reply in the JOINing process.
6580 * Added to USERS command in silcd/command_reply.c to join the client,
6581 we didn't use to know about, to the channel after we've created
6582 a client entry for it. Also, for clienet we did know already still
6583 check whether it is on the channel or not and add it if not.
6585 * Removed silc_server_command_join_notify as the function and its
6588 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6590 * Changed the client's pending command handling to the same as the
6591 server's pending command handling. It is also now possible to
6592 execute command reply functions from other command reply
6593 function as the function callbacks for commands and command
6594 replies are one and same. The pending commands are not static
6595 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6596 in client connection context. Thus, pending commands are server
6597 connection specific as it is convenient.
6599 Changed the function silc_client_command_pending and
6600 silc_client_command_pending_del and added new function
6601 silc_client_command_pending_check. Removed the
6602 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6605 * Added cmd_ident, current command identifier, to the client
6606 connection context in lib/silcclient/client.h to keep track on
6607 command identifiers used in command sending. Client's command reply
6608 function handling now supports the mandatory command identifiers.
6610 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6611 funtions in client to fully support pending command callbacks.
6613 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6614 as one of the arguments to the application in the command reply
6617 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6618 before first releasing SILC but came back. Now it is removed again
6619 and should come back nomore. The FORWARDED flag was used only
6620 by the JOINing procedure by forwarding the command packet to router.
6621 Now, the JOINing procedure has been changed to more generic (due
6622 to various router environment issues) and FORWARDED is not needed
6623 anymore for anything. The protocol specification is yet to be
6626 Now, removed silc_server_packet_forward from server and the flag
6627 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6629 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6631 * Renamed NAMES command to USERS command. The NAMES was named that
6632 due to historical reasons. Now it is renamed. Also, rewrote
6633 parts of the USERS command. The nickname list is not sent anymore
6634 by the server. Only Client ID and mode lists are sent in the USERS
6635 command. Changed this also to the protocol specification.
6637 The client now resolves the names and stuff after it receives
6638 the USERS list from the server when joining to the channel.
6640 * WHOIS and IDENTIFY commands has been changed to support multiple
6641 Client ID's per command. One can now search for multiple users
6642 in the network by sending only one WHOIS or IDENTIFY command.
6643 Changed the code and the protocol specifications.
6645 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6646 uses silc_server_command_whois_parse to parse the request. */
6648 * If normal server, do not parse the WHOIS and IDENTIFY requests
6649 before sending it to the router. Saves some time.
6651 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6653 * Fixed JOIN command on client library. Wrong number of arguments
6654 used to crash the client.
6656 * Added silc_server_channel_has_global function to check whether
6657 channel has global users or not.
6659 * Added silc_server_channel_has_local function to check whether channel
6660 has locally connected clients on the channel.
6662 * The silc_server_remove_from_one_channel now checks whether the
6663 channel has global users or not after given client was removed from
6664 the channel. It also checks whether the channel has local clients
6665 on the channel anymore. If it does not have then the channel entry
6666 is removed as it is not needed anymore.
6668 * The silc_server_notify now checks on JOIN notify whether the joining
6669 client is one of locally connected or global. If it is global then
6670 the channel has now global users on the channel and that is marked
6671 to the channel entry. Also, it now saves the global client to
6672 global list who is joining and JOINs it to the channel. This is
6673 for normal server, that is.
6675 Changed silc_server_send_notify_on_channel,
6676 silc_server_packet_relay_to_channel and
6677 silc_server_packet_send_to_channel check if we are normal server
6678 and client has router set (ie. global client) do not send the
6679 message to that client, as it is already routed to our router.
6681 * Implemented LEAVE notify type handling in silc_server_notify
6684 * Tested LEAVE command in router environment successfully. Tested
6685 with two routers, two servers and two clients.
6689 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6691 * Implemented SIGNOFF notify type handling in silc_server_notify
6694 * silc_server_remove_id now removes the client entry from all channels
6695 it has joined and thusly sends SIGNOFF notify type.
6697 * Rewrote the NAMES list generation in server by removing two excess
6698 loops. The lists are created now inside one loop.
6700 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6702 * silc_server_remove_channel_user checks now also global list
6703 for channel and client.
6705 * silc_server_new_channel_user checks now both local and global
6706 list for channel and client. Fixed a bug in client id decoding.
6707 Used to decode wrong buffer.
6709 * silc_server_channel_message checks now both local and global
6710 list for channel entry.
6712 * Tested channel joining (hence JOIN) in router environment
6713 successfully. Tested with two routers, two servers and two
6716 * Tested channel message sending in router environment successfully.
6718 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6720 * Added silc_server_save_channel_key into server.[ch] to save the
6721 received channel key in Channel Key payload processing. It is
6722 also used in JOIN command reply handling.
6724 Equivalent function silc_client_save_channel_key added into
6725 client.[ch] into client library.
6727 * Changed JOIN command reply to send information whether the channel
6728 was created or not (is existing already) and the channel key
6729 payload. Changed protocol specs accordingly.
6731 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6732 the request was sent by ID and not by nickname. Crashed on
6735 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6737 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6738 now correctly save the received data.
6740 * silc_server_free_sock_user_data now notifies routers in the
6741 network about entities leaving the network.
6743 At the same time implemented functions silc_server_remove_id
6744 and silc_server_send_remove_id to receive and send REMOVE_ID
6745 packets. The packet is used to notify routers in the network
6746 about leaving entities. The ID removed will become invalid in
6749 * Added function silc_idlist_del_server into server. Removes and
6750 free's server entry from ID list.
6752 * silc_server_private_message function now checks, if we are router,
6753 that the destination ID really is valid ID, naturally.
6755 * In router when NEW_ID packet is received (for new client) the
6756 hash of the Client ID is saved in the ID Cache but the
6757 client->nickname is set to NULL, instead of putting the hash
6760 IDENTIFY command now also checks that client->nickname must be
6761 valid. If it is not if will request the data from the server who
6762 owns the client. Added new function
6763 silc_server_command_identify_check.
6765 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6766 to set the command to already allocated Command Payload.
6768 * Tested private message sending in router environment with two
6769 routers, two servers and two clients. Fixed minor bugs and now
6772 * Fixed segfault from client's NAMES command. Used to crash if
6775 * Forwarded packets must not be routed even if it is not destined
6776 to the receiver. Changed server code comply with this.
6778 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6780 * Added `require_reverse_mapping' boolean value to ServerParams
6781 structure. If TRUE (not default) the server will require that
6782 the connecting host has fully qualified domain name.
6784 If the reverse mapping is not required and hostname could not be
6785 found the IP address is used as hostname.
6787 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6789 * Implemented version string checking to both client and server.
6790 The check is incomplete currently due to the abnormal version
6791 strings used in development version of SILC.
6793 * Changed all command functions in server to use the new
6796 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6798 * Changed char *data to unsigned char *data in ID Cache system to
6799 support binary data as ID Cache data. Changed code to support
6800 binary data in lib/silccore/idcache.c.
6802 * Renamed silc_server_packet_relay_command_reply to
6803 silc_server_command_reply as it is normal packet receiving
6804 function. Rewrote the function to accept command replys for
6805 servers and not only for clients.
6807 * Mark remote router always as registered server if we are connecting
6808 to it. Otherwise, commands sent by the router to us are ignored.
6810 * All ID List find routines now returns the ID Cache Entry pointer
6811 as well if requested.
6813 * WHOIS command works now in router environment, tested with two
6814 routers, two servers and two clients.
6816 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6817 in router environment (as it is almost equivalent to WHOIS) but
6818 hasn't been tested thoroughly. Added new functions:
6820 silc_server_command_identify_parse
6821 silc_server_command_identify_send_reply
6822 silc_server_command_identify_from_client
6823 silc_server_command_identify_from_server
6825 * Disabled route cache adding because adding two different ID's with
6826 same IP replaces the old cache entry thus giving wrong route.
6827 The entry->router->connection is always the fastest route anyway
6828 so route cache may not be needed. Of course, new routes maybe
6829 established after receiving the ID when the entry->router->connection
6830 might not be anymore the most optimal.
6832 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6834 * Add route cache for received ID for fast routing.
6836 * Added silc_server_packet_route to route received packet on router
6837 that is not destined to us.
6839 * Renamed silc_server_get_route to silc_server_route_get.
6841 * Added id_string and id_string_len fields into SilcServer to
6842 include encoded ServerID for fast comparing without excess
6843 encoding of the ID's.
6845 * Cleaned up WHOIS command on server side. Added following static
6848 silc_server_command_whois_parse
6849 silc_server_command_whois_check
6850 silc_server_command_whois_send_reply
6851 silc_server_command_whois_from_client
6852 silc_server_command_whois_from_server
6854 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6855 arguments in command replies. All command functions should be
6856 updated to use this macro.
6858 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6860 * Minor typo fixes on command reply handling on server.
6862 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6864 * Added silc_server_command_add_to_channel internal routine to add
6865 the client to the channel after router has created the channel and
6866 sent command reply to the server.
6868 * Added generic silc_server_send_command to send any command from
6871 * Use static buffer with ID rendering instead of duplicating data.
6873 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6875 * Fixed a channel user mode bug when joining to a channel server gave
6876 everybody channel founder rights, oops.
6878 * We mark ourselves as the router of the incoming server connection
6879 if we are router ourselves. This way we can check in some packet
6880 sending functions whether it is locally connected server. For
6881 incoming router connections we put NULL.
6883 * For router sending packets locally means now always sending the
6884 packet cell wide; to local clients and local servers. For normal
6885 server sending packet locally means sending it to only local
6888 * Fixed the JOIN command to really work in router environment. If the
6889 channel is created it is always created by the router. Router is
6890 also responsible of making the initial joining to the channel,
6891 sending JOIN notify to the sending server and distributing
6892 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6893 does not exist server doesn't do anything else but forward the
6894 command to the router which performs everything.
6896 * Added silc_server_send_channel_key function to send the Channel Key
6899 * Added silc_server_create_channel_key to create new channel key. The
6900 channel key is now re-generated everytime someone joins or leaves
6901 a channel, as protocol dictates. Note: channel->key_len is the
6904 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6906 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6907 packet_receive.[ch] to separate packet sending and receiving
6908 routines. The server.[ch] now includes everything else including
6909 actual packet processing (writing and reading data) and other
6912 Renamed silc_server_private_message_send_internal to
6913 silc_server_send_private_message. The routine is still though
6914 used only to relay private messages as server does not send
6915 private messages itself.
6917 Renamed silc_server_new_channel to silc_server_create_new_channel
6918 and added new function sicl_server_new_channel that handles the
6919 incoming New Channel packet. Added also new sending function
6920 silc_server_send_new_channel to send New Channel Payload.
6922 * Added new function silc_server_notify to process incoming notify
6923 packet to the server/router. Server may then relay the notify
6924 to clients if needed.
6926 * Added new function silc_server_new_channel_user to process incoming
6927 New Channel User packet. Router will redistribute the packet and
6928 send JOIN notify to its local clients and locally connected servers
6929 if needed. Normal server will send JOIN notify to its local client
6930 on same channel when received this packet. Added also corresponding
6931 sending function silc_server_send_new_channel_user to sent the
6934 * Added boolean route argument to send_notif_to_channel and
6935 packet_send_to_channel functions to attempt to route the packet
6936 if it is TRUE and send only locally if it is FALSE.
6938 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6940 * silc_server_replace_id now broadcasts the received replace ID
6941 packet if it is not broadcast packet already. The router must
6942 broadcast to inform other routers about changed ID.
6944 * Added backpointer to server's router into SilcServer context in
6945 silcd/server_internal.h.
6947 * Fixed silc_server_packet_broadcast to send correct broadcast
6950 * The channel key is now distributed to the local client as soon
6951 as it is received from the router (in router environment) so that
6952 no other packet may be sent for the channel until client has
6955 * silc_server_remove_channel_user now broadcasts the received
6956 Remove Channel User packet if it is not broadcast packet already.
6957 The router must broadcast to inform other routers about removed
6960 * Added users field into SilcPacketContext that is a reference count
6961 of the context. One can increase the reference count by calling
6962 silc_packet_context_dup which is now changed to just increase the
6963 reference count instead of duplicating the data. The reference
6964 count is decresed by calling silc_packet_context_free that will
6965 free the data after the reference count hits zero.
6967 For now on the packet context and everything allocated into it
6968 (including the raw packet from network) must be freed by calling
6969 the new silc_packet_context_free function. Added also new function
6970 silc_packet_context_alloc that must be used now to allocate the
6971 context. This also means that if a routine is asynchronous from
6972 silc_[client/server]_packet_parse_type the packet context must
6973 be duplicated by calling silc_packet_context_dup. Otherwise it
6974 gets free'd after silc_[client/server]_packet_parse_type returns.
6975 Also, one must remember that if packet is duplicated then its
6976 reference count must be decresed by calling the free function as
6977 many times as it was duplicated.
6979 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6980 from both client and server.
6982 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6984 * Made joining to a channel working in router environment.
6986 * Cleaned up JOIN command on server side and create function
6987 silc_server_command_join_channel internal routine to make the
6990 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6992 * Changed silc_command_pending list to SilcDList. Also, added
6993 `ident' field to SilcServerCommandPending structure to identify
6994 the reply and to call correct callback.
6996 Added silc_server_command_pending_check function to replace the
6997 corresnponding macro. The silc_command_pending list is not
7000 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7001 to set identifier to previously allocated Command Payload. It
7002 is used to set identifier for command when resending Command
7005 * Added silc_command_payload_encode_payload to encode Command
7006 Payload buffer from SilcCommandPayload structure.
7008 * Added silc_argument_payload_encode_payload to encode Argument
7009 payload buffer from SilcArgumentPayload structure.
7011 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7013 * Changed WHOIS command to support router connection on server side.
7014 The whois request is always sent to router unless the server is
7015 standalone server. After server has received the reply from the
7016 router will it send the reply to the client.
7018 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7019 broadcast received broadcast packet. The function is used only
7020 by router. The broadcast packet is always sent to the router's
7023 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7024 render given ID to printable string, for log files for example.
7026 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7028 * Made basic router to router connections working. At least they
7029 can now connect to each other but nothing really works the way
7030 they are supposed - yet.
7032 * Added new initiator token to RouterConnection configuration
7033 file in silcd/serverconfig.[ch]. It is used to tell whether we
7034 are the initiator to the remote router or whether we'll expect
7035 the other end to connect.
7037 * Moved registering of listener task to silc_server_init, hence
7038 the server starts listenning as soon as it is run, even if it
7039 does not have connections to other routers. Let's see how well
7042 * Changed default connection retry timeouts for more suitable in
7045 * Removed cipher and such arguments from silc_idlist_add_client
7046 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7047 Added new function silc_idlist_add_data to add the keys and stuff
7050 * Added SilcIDListData structure and added it to SilcClientEntry
7051 and SilcServerEntry as their first field in the structure. This
7052 way we can explicitly cast the ID entries to the SilcIDListData
7053 structure and get common data for the entries. In past, we had
7054 to first check what type of connection it is and then cast it to
7055 correct ID entry type. Now, we can directly cast the opaque
7056 pointer to the SilcIDListData (no matter what ID entry it actually
7057 is) and get the data needed.
7059 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7061 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7062 in some circumstances even if threre were timeout tasks, though not
7063 IO tasks, but tasks anyway. Now fixed.
7065 * Defined SilcServerConnection structure to hold connection specific
7066 stuff about directly connected servers and routers. The definition
7067 is currently in silcd/server_internal.h. I thought about having
7068 a bit more important role fro this struct but for now it is used
7069 only when connecting to other server (or router actually).
7071 * Added connecting retry support in server when connecting to
7072 router(s). The retry feature implement exponential backoff
7073 algorithm. Also, added SilcServerParams structure to hold default
7074 parameters for server. For now, it include these retry settings
7075 and are hard coded. After server is moded to be as Silc Server
7076 Library this structure will be more important.
7078 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7080 * Changed client librarys channel->clients table to SilcList and
7081 changed code accordingly.
7083 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7085 * Changed client's channel table to SilcList and changed code
7086 accordingly. Also changed SilcChannelClientEntry to include back-
7087 pointer to the channel so that client entry can use that structure
7088 as list as well and we have fast cross-reference to the channel.
7089 This change dramatically decreased the complexity of channel
7090 handling with client entry and vice versa (removed one extra
7091 loop when searching for channel entry from many functions).
7093 * Changed server->sim from table to SilcDList and changed code
7096 * NAMES command can now be used from user interface. It will show
7097 the user list on the channel, neatly.
7099 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7100 Code now saves realname of the user if it becomes available.
7102 * Renamed configure.in to configure.in.pre and made ./prepare
7103 script to automatically add correct version string to
7104 configure.in which it creates from configure.in.pre.
7106 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7108 * NAMES command reply now shows users mode with the nickname when
7111 * Moved silc_client_ch[u]mode[_char] functions from
7112 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7113 place sucks, they are utility functions and should be in some
7116 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7118 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7121 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7125 * Added TRQ (efficient deque and list library) into lib/trq. This is
7126 a very good list library that is currently used in the SILC. Defined
7127 SilcList API over the library because I didn't like the API very
7128 much. See lib/trq/silclist.h for the API and examples of how to
7129 use the API. Fixed various places in the code to use the new
7130 SilcList API. The SilcList is meant for lists that has a structure
7131 already defined as a list. It is not suitable to add just some
7132 context to the list (in TRQ, the context is the list actually).
7134 So, I defined SilcDList that can be used for the purpose where
7135 predefined list structure does not exit. This can be used as
7136 such list. Now some context just can be added to the SilcDList.
7137 Currently this list is not used in the SILC just yet, though there
7138 are a lot places where this can replace dynamically allocated
7139 tables and I will fix these places, later, to use SilcDList.
7140 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7141 and use TRQ internally).
7143 Also fixed some annoying warning messages that the original TRQ
7144 code generated. Also minor changes to TRQ's Makefile.in.
7146 * Added support for querying by Client ID to both WHOIS and
7147 IDENTIFY commands into server, as required by the protocol.
7149 * Removed method function pointers from SilcBuffer structure. They
7150 weren't used to anything and just increased the context size for
7151 no good reason. This change also made silc_buffer_alloc and
7152 silc_buffer_free functions inline functions.
7154 * Disabled command flooding detection support until it's fixed so
7155 that it accepts commands in but does not execute them more than once
7158 * Added silc_net_localhost(), to return local hostname, into
7159 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7160 that must be initialized before calling silc_client_init.
7162 * Added new function: silc_server_send_notify_on_channels to send
7163 notify messages to all channels client has joined. It is assured
7164 that the message is sent only once per client.
7166 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7167 lib/silcutil/silcutil.[ch] as silc_format function. The new
7168 function is generic and is used by server as well, not only by
7169 the logging routines.
7171 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7172 the provided version string was not acceptable. Added new function:
7173 silc_ske_check_version into lib/silcske/silcske.h. The function
7174 must be implemented by the application (client or server) and it
7175 does not reside in the SKE library. The function checks the version
7176 string remote end sent.
7178 * Added back pointers (to opaque context and to SilcSocketConnection)
7179 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7181 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7182 duplicate packet context structure.
7184 * Changed `notify' client operation to send same arguments as client
7185 receives from server except for ID's. ID's are mapped to correct
7186 ID entry and that is returned. Also, if channel entry is not sent
7187 by server but the notify is for channel the channel entry is sent
7188 to application (otherwise application doesn't know that it is for
7189 channel (library gets it from packet's Destination ID)).
7191 * Added silc_client_remove_from_channels into client library to
7192 remove a client from all channels it has joined to. Used when
7193 received SIGNOFF notify from server. Added also new function
7194 silc_client_replace_from_channels to replace old ID entry with
7195 new ID entry on all channels. Used when received NICK_CHANGE
7198 * Fixed ID Cache list handling in silc_idlist_get_client in
7199 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7200 to get (or query) client by ID.
7202 * Updated TODO list.
7204 * Added connection authentication status message defined by the
7205 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7206 support for these into the code in client and server side.
7208 * Added generic function silc_client_send_command to send any command
7209 with variable argument list. Application should use this function
7210 to send commands if the command functions provided by the library
7211 does not suite for the application's user interface needs.
7213 * Added new `failure' client operation. Application is notified about
7214 received failure packet if client is executing a protocol. In this
7215 case the protocol's execution has failed.
7217 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7218 is required by the protocol.
7220 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7221 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7224 * Added status flag to SilcSKE object to indicate realtime status
7225 of the SKE protocol.
7227 * Application receives now exactly same command reply arguments as
7228 the library receives from server. However, if ID is received the
7229 corresponding ID entry is returned to the application (eg. Client
7230 ID is mapped to correct SilcClientEntry entry and that is returned).
7231 Changed command_reply client operation due to this change.
7233 * Changed all ID's in commands and in command replys as ID Payloads.
7234 Change affected both client and server side codes.
7236 All ID's sent in SILC network (with execption of ID's in SILC
7237 Packet header) are sent in ID Payload to support variable length
7240 * Server now notifies nick changes and notifies all clients on
7241 the channels about the new nickname (about the new Client ID,
7244 * Implemented CMODE command to change channel modes. Supports all
7245 channel modes defined by the protocol specs except ban and invite
7246 lists. (Also, private channel key mode is supported but support for
7247 setting private channel key in client is missing, thus, this mode
7248 has no effect on client side (except that server requires that the
7249 client uses private channel key and normal channel traffic does not
7252 Also, invite mode works per se, but INVITE command does not work
7253 yet correctly, so you can set channel as invite only channel but
7254 inviting clients to the channel does not work (it is yet to be
7255 thought what's the best way to do it).
7257 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7258 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7259 Implemented CUMODE command to change user's mode on the channel.
7260 Supports all modes defined by the protocol specs.
7262 * Added NAMES command reply to return users modes on the channel.
7264 * Removed unnecessary and slow ciphers from lib/silccrypt.
7266 * Set SO_KEEPALIVE option to connection sockets by default.
7268 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7270 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7271 redefined the Notify Payload into protocol specs.
7273 * Added silc_id_payload_parse_id to get ID directly from raw
7276 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7278 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7279 accept searching by Client ID as well.
7281 * Added support for LEAVE and SIGNOFF notify types in client library.
7283 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7284 to parse ID Payload from raw data.
7286 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7288 * Added flags parameter into silc_ske_assemble_security_properties
7289 function in lib/silcske/silcske.[ch].
7291 * Changed notify client operation to fit better for notify messages
7292 sent by server. The notify payload received from server is now
7293 passed to the application (after parsing it to SilcNotifyPayload).
7294 It is application's responsibility to retrieve the arguments
7295 from the payload and show the message the way it wants. The message
7296 sent by server is implementation specific.
7298 * Changed public keys to comply with the protocol specification.
7299 Old public keys are not supported anymore and are not compatible.
7301 * Removed nickname from Channel Payload as the latest draft removed
7302 it. The client must resolve the nickname from the NAMES command
7303 reply received when it joined the channel.
7305 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7307 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7309 * Fixed some errors in protocol specification drafts.
7311 * Created lib/silccore/silcnotify.c to implement Notify Payload
7312 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7313 generic payloads described by protocol specifications. The file
7314 includes implementations for ID Payload and Argument Payload.
7316 * Changed Command Payload implementation to use the new Argument
7317 Payload. Changed command_xxxx_payload to command_payload_xxxx
7318 to comply with SILC coding conventions.
7320 * Added suppport for Argument Payload handling in Notify Payload
7321 implementation as protocol requires it. Added the new support
7322 into server and client lib as well.
7324 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7326 * Added support for multiple nicknames on same channel. [n] is
7327 added locally to the nickname if there are more than one same
7328 nicknames on the channel.
7330 * Server now sends all nicknames that matched WHOIS request.
7331 Client also shows the list received from server.
7333 * Added TOPIC command to client side. User can now set and show
7334 current topic on channel.
7336 * Added MOTD command to client and server. Also, server sends the
7337 motd when client connects to the server.
7339 * Changed version strings to comply ISO 8601.
7341 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7343 * Fixed protocol error handling in client library. It should now
7344 cope even if the SKE fails for some reason.
7346 * Made new protocol specification drafts for submitting to IETF.
7348 * Implemented TOPIC command to server in silcd/command.c.
7350 * Added two new notify types into lib/silccore/silcnotify.h:
7351 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7352 notify nickname change and topic setting/change on a channel.
7354 * API change of command_reply operation in client library. The
7355 application gets now the status type received from server as well.
7357 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7359 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7361 * Cras fixed and optimized the packet handling even further and
7362 it should work now. Minor change to the prototype of function
7363 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7365 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7367 * Added new function into lib/silcutil/silcschedule.[ch]:
7368 silc_schedule_with_fd to select() a specified fd. The function
7369 returns after timeout expires or data arrives or goes. The
7370 function is used by packet routines to wait that all data is
7371 received from network.
7373 * Fixed data reading from network in lib/silccore/silcpacket.c.
7374 The code now assures that all data is read from the fd and then
7375 continues packet processing. This was a bug fix since the code
7376 used to drop some data in some circumstances.
7378 * Added new function into lib/silcclient/client.[ch]:
7379 silc_client_start_key_exchange to start key exchange after
7380 connection has been established to server. The code internally
7381 now uses this funtion but its main purpose was to provide it
7382 for applications that perform their own connecting. After
7383 application has created a connection it merely calls this
7384 function to start the key exchange between client and server.
7385 The library takes care of everything else after that.
7387 Updated also lib/silcclient/README to explain the usage of
7390 * Do not send to application information that connection has
7391 been established. Application gets notified it by connect
7394 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7396 * Applied cras's patch to add silc_schedule_one function. The
7397 function runs scheduler once and returns.
7399 * Fixed the scheduler after cras messed it up. The timeout
7400 handling works now as it's supposed to work.
7402 * Added into lib/silccore/ silcnotify.h to include notify
7403 message types support. Changed silc_server_send_notify*
7404 functions, in server.[ch], to support those new notify types.
7405 Added the support for the notify types into client library,
7406 as well. Added new notify client operation into ops.h in
7409 * Changed silc_server_packet_send_to_channel to send normal
7410 packets instead of just channel message packets. The function
7411 is now used to send the notify packets to channels. It is not
7412 used to send channel message packets anymore, as server never
7415 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7416 va_arg()s as it seems to require it nowadays. I guess, if SILC
7417 is compiled with older va_arg() the new code should work anyway.
7419 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7421 * Splitted core library. Core library (lib/silccore) includes
7422 now only SILC protocol specific core (and common) components.
7423 Created new utility library (lib/silcutil) that includes more
7424 generic purpose stuff. The stuff for util library was taken
7425 from the old core library. This was minor and easy split.
7427 * Created SILC Client Library (lib/silcclient) that includes
7428 implementation of the SILC client without user interface. This
7429 was major move from silc/ directory. The code has been changed
7430 so that it is transparent towards the user interface. The
7431 silc/ directory includes now the same user interface as before
7432 and it uses the new client library. Read lib/silcclient/README.
7433 Basicly, the client library performs everything else related
7434 to SILC except user interface handling. Also, configuration
7435 files are considered to be part of user interface and library
7436 does not handle them.
7438 This change also changed a lot of structures, function naming etc.
7439 Most important change was that SilcClientWindow object was
7440 renamed to SilcClientConnection in the client library. Created
7441 also new file lib/silcclient/ops.h. Also added new files
7442 silc/local_command.[ch] and silc/client_ops.[ch].
7444 All these changes were made to make it easier for user interface
7445 designers to create what ever user interface for the SILC client
7448 It is also expected that the server will be moved to lib
7449 directory as well and SILC Server Library will be created;
7450 sometimes in the future.
7452 * Removed Local commands from lib/silccore/silccommand.h as
7453 they are application specific and new client library does not
7454 handle any of those anymore.
7456 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7457 old client implementation in silc/.
7459 * Added support for callback functions in SILC_LOG_* macros.
7460 Application can now set its own callbacks that will be called
7461 instead of using the default functions that will always print
7462 the debug messages to stderr (or stdout). Also, debugging can
7463 now be disabled by setting silc_debug to FALSE and re-enabled by
7464 setting it to TRUE. Note, that logging will still work even
7465 if debugging is disabled.
7467 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7468 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7469 silc_log_reset_debug_callbacks.
7471 * To enable debugging in silc client one must give now -d
7472 option on command line.
7474 * Changed silc_schedule_init to automatically allocate task queues
7475 if they are not allocated before calling it.
7477 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7479 * Added GMP 3.1 into math library.
7481 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7483 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7484 a channel in SILC network. The packet is used by servers and
7485 routers to notify other routers that user has left a channel.
7486 This little feature was missing until now. Added the feature
7487 to protocol specification as well.
7489 Added functions: silc_server_send_remove_channel_user and
7490 silc_server_remove_channel_user into server.[ch].
7492 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7493 lib/silccore/silcpacket.h. However, they are not implemented
7496 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7498 * Fixed joining to a channel and sending channel messages
7499 between server and router. The channel message sending should
7500 now work inside a cell.
7502 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7504 * Fixed the private message sending between server and router.
7505 The private message sending should now work inside a cell.
7507 * Added silc_server_replace_id into server.[ch] to replace
7508 existing ID in the SILC network.
7510 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7511 and silc_idlist_replace_server_id into idlist.[ch] in server.
7513 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7515 * Fixed the server to server connections. Server can again now
7516 connect to router. Router to router connections probably does
7519 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7521 * Added dynamic protocol registering support. Now protocols can
7522 registered and unregistered on the fly. Patch by cras.
7524 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7526 * Added lib/contrib directory to hold routines that some platforms
7527 don't have but are needed by SILC.
7529 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7530 into lin/contrib to provide getopt() and getopt_long() for
7531 those who don't have it.
7533 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7535 * Added AWAY command to client. When away message is set and
7536 client receives a private message packet the client automatically
7537 replies to the sender with the away message.
7539 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7540 bug seemed to be the cause of recent problems when compiling
7543 * Added version detection support to SKE protocol specification
7544 and added the new changes to the SKE implementation as well.
7545 There were other minor changes in the SKE protocol as well.
7547 Many changes in lib/silcske/silcske.[ch] and in
7548 lib/silcske/payload.[ch].
7550 * Added ^U functionality, clear input line. Patch from cras.
7552 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7554 * Mainly small bugfixes on core library. Fixed some debugging
7555 logging and buffer overflow in silclog.c.
7557 * Updated config.sub and config.guess on the distribution tree.
7559 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7561 * Added command lagging support in server. Client may execute
7562 commands now only once in two seconds.
7564 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7566 * Optimized packet reception. MAC computation and checking is now
7567 also more optimized. A lot previously duplicated code is now
7568 used as generic by both client and server.
7570 * Fixed key pair generation in clientutil.c
7572 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7574 * Added into lib/silccore/silcbufutil.[ch] new function;
7575 silc_buffer_realloc.
7577 * Moved generic packet sending/encryption functions to
7578 lib/silccore/silcpacket.[ch] from client and server. Some
7579 rewriting of the functions.
7581 * Moved all generic packet reception/decryption functions to
7582 lib/silccore/silcpacket.[ch] from client and server. The
7583 packet processing is now much cleaner in both client and server.
7584 These were major changes in both client and server.
7586 * Created many common functions in server to do packet sending.
7587 Previously code were duplicated a lot, this has been removed
7590 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7592 * Rewrote major parts of the ID cache system. Don't know
7593 whether it is better now or not but at least the API is more
7596 * Major rewrite on ID cache stuff on client because of the ID
7597 cache API changes. Added idlist.c to client.
7599 * Also major rewrite on ID cache stuff on server as well.
7600 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7601 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7602 in hand, instead they are all put into the ID cache system now.
7603 All server_idlist_* routines uses ID cache now instead of
7604 traversing its own lists (those lists does not exist anymore).
7605 SilcIDList though still exists. Also, SilcXXXEntry's are
7608 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7610 * Finally made the SKE implementation compliant to the protocol
7611 specification. All mp integers are now binary encoded as
7612 opposed being HEX encoded.
7614 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7617 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7618 functions: silc_[encode/decode]_pem. Also added function
7619 silc_encode_pem_file to PEM encode with newlines ('\n') for
7622 * SILC public keys are now encoded either PEM or binary. Same
7623 option is for private keys as well. By default private keys
7624 are binary encoded and public keys PEM encoded. Silly HEX
7625 encoding were removed.
7627 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7628 function to create fingerprints.
7630 * Fixed a bug in SHA1; does not change the original data anymore.
7632 * Partly implemented INFO command on client and server side.
7633 Fixed CLEAR command. Changes to SERVER command; show current
7634 server(s) when giving command without arguments. Added
7635 VERSION command to client.
7637 * Added check to server that unregistered connections cannot
7638 execute commands (unless it is specificly allowed).
7640 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7642 * Fixed screen refresh.
7644 * Fixed channel joining bug from client. On some circumstances
7645 client tried to join to a channel it had already joined.
7647 * Added public key verification process into client's protocol.c.
7648 The client now verifies the public key from user and saves
7649 it into ~./silc/serverkeys/ directory.
7651 Added into: clientutil.[ch]: silc_client_verify_server_key.
7653 * Changed SKE protocol's silc_ske_initiator_finish function
7654 to accept callback function that verifies the received public
7655 key. Removed old silc_ske_verify_public_key function.
7657 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7659 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7660 silc_pkcs_private_key[_data]_set.
7662 * Made the password and public authentication more cleaner in
7663 server's protocol.c.
7665 * Removed historic and obsolete protocol `channel_auth' from
7666 both client and server.
7668 * Removed wrong way of sending command status messages from
7669 server to client in server's command.c. The old way violated
7670 protocol specification.
7672 Changes to silccore/silccommand.[ch]: removed
7673 silc_command_encode_status_payload -> not needed anymore,
7674 changed silc_command_encode_payload_va to accept extra
7675 argument on variable argument list. The argument type must
7676 now be provided to the function. Also, added new function:
7677 silc_command_encode_reply_payload_va which is same as
7678 normal command_encode_payload_va except command status type
7679 is provided as extra argument.
7681 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7683 * Added ~./silc directory handling. The directory includes the
7684 public and private keys for the client.
7686 Added silc_client_check_silc_dir, silc_client_create_identifier
7687 and silc_client_load_keys.
7689 * Implemented SILC protocol compliant public key. Added public
7690 and private key saving to and loading from files.
7692 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7693 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7694 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7695 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7696 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7698 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7699 silc_pkcs_load_[public/private]_key.
7701 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7703 * Added silc_server_get_route (route.[ch]) to get connection
7704 data for the fastest route for given ID.
7706 * Implemented INVITE command on client and server. The command
7707 were re-defined in the SILC Protocol Specification and the
7708 implementation now complies with the specification.
7710 * Implemented PING command on client and server.
7712 * Implemented NAMES command on client and server. The server side
7713 supports currently only normal server not router server yet.
7714 Some changes to NAMES definition in SILC protocol specification.
7716 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7718 * Implemented LEAVE command on client and server.
7720 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7721 again. This change was made to the protocol as well. Server
7722 should not violate the protocol specification anymore.
7724 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7726 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7727 was tested. SOCKS4 was not but should work anyway.
