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

536 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
537 to avoid collisions with other libraries using same type names
540 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
542 * Added `prefer_ipv6' argument to the functions
543 silc_net_gethostbyname[_async]. If it is TRUE it will return
544 IPv6 address over IPv4. If FALSE IPv4 address is returned
545 even if IPv6 address was found. Affected files
546 lib/silcutil/silcnet.[ch].
548 * Added support silc_net_create_connection[_async] to fallback
549 to IPv4 address if IPv6 address could not be used (like if

562 application does not need to define them. Affected file
563 includes/silcincludes.h.
565 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
566 old name went against naming convention. Applications now
567 include "silcclient.h" instead of "clientlibincludes.h".
568 Removed includes/clientlibincludes.h, it is redundant now.
570 * Renamed includes/version.h to silcversion.h.
572 * Added really preliminary support for OS/2 into the util
573 library. Only thread & mutex API is implemented, others
574 are still to be implemented. Created the lib/silcutil/os2/
575 directory. Created also file includes/silcos2.h.
577 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

624 client_entry->channels hash table everytime nick is changed.
625 Affected file lib/silcclient/client.c.
627 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
629 * ROBOdoc documented the lib/silcske/silcske.h, and improved
630 the SKE interface a bit.
632 * Fixed padding problem in PKCS#1. The padding was not actually
633 random since the random number generator was used incorrectly.
634 This security bug affects only when encrypting with PKCS#1, and
635 it is not currently used at all in SILC. SILC only use signing
636 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
638 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

704 * Added new configuration options and blocks:
705 keepalive_secs, reconnect_count, reconnect_interval,
706 reconnect_interval_max, reconnect_keep_trying and
707 require_reverser_lookup. Added ConnectionParam block, and
708 implemented the connection parameters when connecting as
709 initiator and when accepting connections as responder.

712 whether given configuration value has been given already.
714 Affected files silcd/serverconfig.[c], server.[c].
716 * Splitted the doc/example_silcd.conf.in. Separated the crypto
717 algorithm parts and created new file silcalgs.conf, that
718 is now included from the example_silcd.conf.in.
720 * Optimized the silc_server_connect_to_router_second to take
721 the connection configuration object from the SilcServerConnection
722 object instead of finding it during the connecting phase.
723 Added the configuration object to SilcServerConnection struct.
724 Affected files silcd/server_internal.h, server.c.

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

806 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
808 * Fixed the file transfer's key agreement payload to include
809 zero port also if the hostname is NULL because it could not
812 Call file transfer monitor callback now also if error occurs
813 during key agreement protocol.
815 Changed the silc_client_file_send interface to return the
816 SilcClientFileError instead of session id. The session ID
817 is returned into pointer provided as argument.

834 file lib/silcutil/silclog.c.
836 * Fixed the channel message payload decryption in the function
837 silc_channel_message_payload_decrypt to not modify the original
838 buffer before it is verified that the message decrypted
839 correctly. Otherwise, next time it is called with correct
840 channel key it won't encrypt since the payload is corrupted.
841 Affected file lib/silccore/silcchannel.c.
843 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

857 become invalid in the callback but it was referenced after
858 the callback returned.
860 Do not allow auto rehashing of hash table during the
861 silc_hash_table_foreach operation, for same reasons as it is
862 not allowed for SilcHashTableList. Affected files are
863 lib/silcutil/silchashtable.[ch].
865 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>

886 users list to SilcHashTable. The affected files are
887 lib/silcclient/idlist.[ch].
889 * Fixed a bug in hash table tarversing. While the hash table
890 is traversed with SilcHashTableList the table must not be
891 rehashed. It is now guaranteed that auto rehashable tables
892 are not rehashed while tarversing the list. Also defined that
893 silc_hash_table_rehash must not be called while tarversing
894 the table. Added function silc_hash_table_list_reset that must
895 be called after the tarversing is over. The affected files are
896 lib/silcutil/silchashtable.[ch].
898 * Changed all hash table traversing to call the new
899 silc_hash_table_list_reset in server and in client library.
901 * Added function silc_client_on_channel to return the
902 SilcChannelUser entry if the specified client entry is joined
903 on the specified channel. This is exported to application as

918 sender's old command identifier was not saved back to the
919 sender's command context, fixed now. The affected file is
922 * Create the key in JOIN command of the router did not return
923 the channel key, added check for this. Affected file is
926 * Fixed a channel ID update bug in JOIN command reply. Do
927 not directly upgrade the ID but call the function
928 silc_idlist_replace_channel_id if the ID was changed.
929 Affected file silcd/command_reply.c.
931 * Fixed memory leaks from command calling if it would fail.
932 Affected file silcd/command.c.

958 * Fixed memory leaks in silc_server_create_new_channel*
959 functions. Affected file silcd/server.c.
961 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
962 which ID was changed. This way the router will send the
963 user list for the channel again, and server won't be in
964 desync in some rare circumstances. Affected file is
965 silcd/packet_receive.c.
967 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1038 of resolving both at the same time. Affected file is
1039 lib/silcclient/command.c.
1041 * Added silc_client_start_key_exchange_cb and lookup the
1042 remote hostname and IP address before starting the key
1043 exchange with server. The affected file is
1044 lib/silcclient/client.c.
1046 * The server's public key is now saved using the IP address
1047 of the server and not the servername for the filename.
1048 The hostname public key filename is checked as an fall back
1049 method if the IP address based filename is not found.
1051 Fixed the GETKEY command to save the fetched server key
1052 in correct filename.
1054 Print the remote server's hostname now when new key is
1055 received during connection process. Affected file is
1056 irssi/src/silc/core/client_ops.c.
1058 * Return always our own public key to the client if it asks

1075 * Do not save client history information in SERVER_SIGNOFF.
1076 Fixes the bug in normal server that it does not detect
1077 the client becoming valid after the server becomes back
1078 online. Affected file silcd/server_util.c.
1080 * Added `sock_error' field into the SilcSocketConnection
1081 context. When error occurs during socket operation (read
1082 or write) the error is saved. Added also new function
1083 silc_socket_get_error to return human readable socket error
1084 message. Affected files are lib/silcutil/silcsockconn.[ch],
1085 lib/silcutil/unix/silcunixsockconn.c, and
1086 lib/silcutil/win32/silcwin32sockconn.c.
1088 * The server now prints the socket error message in the
1089 signoff for client. Affected file silcd/server.c.
1091 * Fixed the `created' channel information sending from router
1092 to server in JOIN command. Checks now whether the channel
1093 really was created or not and set it according that.
1095 Fixed the JOIN command to use the client entry's current
1096 ID during the joining procedure instead of the one it sent
1097 in the command (it is checked though), since it can change
1098 between the packet processing and command processing, and
1099 would just case unnecessary pain in the client end. Affected
1100 file silcd/command.c.
1102 * Fixed a channel key payload sending to use correct channel
1103 ID when the server was forced to change the channel's ID by
1104 router. Router sent the key payload with the old Channel ID.
1105 Affected file silcd/packet_receive.c.
1107 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1109 * Call silc_server_save_channel_key only if the key payload
1110 was provided in the JOIN command's command reply. Affected
1111 file silcd/command_reply.c.
1113 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1115 * Fixed silc_mp_sizeinbase to return the value correctly with
1116 MPI. Affected file lib/silcmath/mp_mpi.c.
1118 * Fixed the stop_server signal to correctly stop the scheduler
1119 and gracefully stop the server when SIGTERM or SIGINT signals
1120 are received. Affected file silcd/silcd.c.
1122 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1124 * Simple handling of TERM and HUP signals. Also added some log
1125 flushing call around. Affected file is
1128 * Fixed small bugs in silclog.c. Now buffering output will take
1129 effect after 10 seconds since startup: This will ensure that
1130 no important startup messages are lost. Also output redirection
1131 will preserve original format ([Date] [Type] message).
1132 Affected file is lib/silcutil/silclog.c.
1134 * Added two options to the config file, in the logging section:
1135 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1136 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1138 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1140 * Do not print the warning about log files not being initialized
1141 more than once to avoid excess logging. Affected file is
1142 lib/silcutil/silclog.c.
1144 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1145 the SIM copying in make install in Makefile.am.pre.
1147 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1149 * Rewritten silclog APIs. Globally interesting changes follows:
1150 silc_log_set_files() changed to silc_log_set_file().
1151 silc_log_set_callbacks() changed to silc_log_set_callback().
1152 ROBOdoc documented silclog header file.
1153 SilcLogCb now returns bool to wether inihibit the default
1154 handler or not (to keep the old behaviour return always TRUE).
1155 The new APIs should also fix the problem of the
1156 silcd_error.log file that was written in the current directory.
1159 Log files streams will remain opened after silc_log_set_file()
1160 call, means less CPU usage notably on high traffic servers.
1161 File streams are now full buffered, and flushed to the disk
1162 every 5 minutes, lesses HD activity and CPU usage.
1163 Messages can be redirected, allowing admins to configure
1164 one single logfile for all server messages.
1165 the silc_log_quick global variable to activate fast-logging.
1166 Affected files lib/silcutil/silclog.[ch]
1168 * Changed some code to conform new silclog APIs. Affected
1169 files are doc/example_silcd.conf.in, silcd/server.c
1170 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1173 * Fixed a memory leak that could occur in some situations.
1174 Affected file silcd/serverconfig.c.
1176 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1178 * Added the silc_client_del_client to remove the client from
1179 all channels as well. Affected file lib/silcclient/idlist.c.
1181 * Fixed the client library to correctly remove the client
1182 from all channels when the client entry is being destroyed.
1183 Affected file lib/silcclient/client_notify.c, command.c.
1185 * Added auto-nicking support to the client library. If the
1186 applicatio now sets client->nickname it will be sent to the
1187 server after connecting by the library. This way for example
1188 SILCNICK (or IRCNICK) environment variables will have effect
1189 and always change the nickname automatically to whatever
1190 it is wanted. Affected file lib/silcclient/client.[ch].
1192 * Renamed silc_server_command_bad_chars to the
1193 silc_server_name_bad_chars and moved it to the
1194 silcd/server_util.[ch]. Added also new function
1195 silc_server_name_modify_bad to return nickname that
1196 includes bad characters as new nickname without those
1197 bad characters. This check and modify is now used in
1198 silc_server_new_client when the username is initially set
1199 as nickname, so it must be checked to be valid nickname.
1200 Affected file silcd/packet_receive.c.
1202 * The nickname length is now taken from the packet for real
1203 and not trusted to strlen() since it clearly can return
1204 wrong length for nickname including bad characters. This
1205 also applies to channel names. Affected file silcd/command.c.
1207 * Removed the lib/silcsilm/modules directory. Modules are now
1208 compiled into the lib/silcsim. Fixed the copying of the
1209 modules to follow symbolic links in Makefile.am.pre.
1211 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1213 * Fixed silc_string_regexify list creation. Fixes bugs with
1214 BAN and INVITE commands in server. The affected file is
1215 lib/silcutil/unix/silcunixutil.c.
1217 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1219 * Removed the command destructor entirely from the server's
1220 command and command reply routines. It is not needed, and
1221 its usage was buggy and caused crashes. Affected files are
1222 silcd/command[_reply].[ch].
1224 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1226 * Cancel protocol and NULL sock->protocol if timeout
1227 occurred during protocol. Affected file silcd/server.c.
1229 * Cancel protocol timeouts always before calling the final
1230 callback, to assure that after final callback is called
1231 no other state will be called for the protocol anymore.
1232 Affected file silcd/protocol.c.
1234 * Print error log if incoming connection configuration could
1235 not be found. Affected file silcd/server.c.
1237 * Fixed JOIN command to correctly save the founder mode
1238 to the client on normal SILC server, when the channel
1239 was created by the router. Affected file silcd/command.c.
1241 * Fixed LIST command (hopefully) to send correct reply
1242 packets. Affected file silcd/command.c.
1244 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1246 * The silc_packet_receive_process now returns FALSE if the
1247 read data was invalid packet, and TRUE if it was ok.
1249 The server now checks that if unauthenticated connection
1250 sends data and its processing fails the server will close
1251 the connection since it could be a malicious flooder.
1253 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1255 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1257 * Make sure the warning about error opening a log file is
1258 printed only once and not everytime it fails (produces
1259 too much useless log). Affected file lib/silcutil/silclog.c.
1261 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1263 * Made the silc_server_daemonise() function more readable.
1264 Affected file silcd/server.c.
1266 * Pid file is now optional, the user may comment it out from
1267 the config file. Removed define SILC_SERVER_PID_FILE, we
1268 don't need a default any longer. Affected file
1269 configure.in.pre, lib/Makefile.am.pre.
1271 * Make some use of the pid file. The server now dies at startup
1272 if it detects a valid pid file on his path. The server would
1273 die anyway in this circumstance, because of the bind() failure.
1274 Affected file silcd/silcd.c.
1276 * No longer compiling lib/dotconf.
1278 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1280 * Fixed JOIN command parsing not to crash. Affected file
1281 lib/silcclient/command.c.
1283 * Fied the NICK_CHANGE notify to add the new client entry
1284 even it is resolved. This removes an <[unknown]> nick
1285 thingy bug in the client. Affected file is
1286 lib/silcclient/client_notify.c.
1288 * Do not try to allocate 0 bytes (efence does not like it)
1289 in lib/silccore/silccomand.c when encoding payload.
1291 * Do not take IRCNICK as nickname in Irssi SILC client since
1292 it is not possible to set nickname before hand connecting
1293 the server (TODO has an entry about adding auto-nicking
1296 * Changed the silc_server_command_pending to check whether
1297 there already exists an pending entry with the specified
1298 command, command identifier and pending callback. This is
1299 to fix IDENTIFY and WHOIS related crashes that may register
1300 multiple pending commands with same identifier. Affected
1301 file silcd/command.c.
1303 * Fixed the server to reconnect to the router even if it
1304 was already reconnecting and EOF was received. This to
1305 fix a possibility that the server wouldn't ever try to
1306 auto-reconnect to the router. Affected file silcd/server.c.
1308 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1310 * Fixed the server's password authentication to use the
1311 length of the locally saved password, and not the one
1312 sent in the packet. Affected file silcd/protocol.c.
1314 * Fixed same password authentication problem in the
1315 Authentication Payload handling routines in
1316 lib/silccore/silcauth.c.
1318 * Yet another password authentication problem fixed with
1319 channel password handling in silcd/command.c.
1321 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1323 * If first character of string in silc_parse_userfqdn is '@'
1324 then do not parse it. Affected file is
1325 lib/silcutil/silcutil.c.
1327 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1329 * Fixed minor bug in IDENTIFY command reply sending, which
1330 caused various weird problems during JOIN when it was
1331 resolving names for users. Affected file silcd/command.c.
1333 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1335 * Fixed the IDENTIFY command reply sending to chech better valid
1336 clients. It was possible to send incomplete list of replies.
1337 Affected file silcd/command.c.
1339 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1341 * Added silc_client_command[s]_[un]register functions now to
1342 dynamically register the commands in client library. Removed
1343 the static table of commands. This allows the client library
1344 to call commands without causing the application to know about
1345 what commands library has called.
1347 Removed the INFO command reply kludge to detect when the command
1348 was called by library. Now library use its own command reply
1349 function for INFO command.
1351 Added function silc_client_command_call to call a command.
1352 Application can use it to call command, not access the structure
1355 Now all commands that are sent by the client library (not
1356 explicitly sent by application) use own command reply functions.
1358 Affected files around lib/silcclient/ and in
1359 irssi/src/silc/core/.
1361 * Fixed the WHOIS command reply sending to chech better valid
1362 clients. It was possible to send incomplete list of replies.
1364 Fixed the WHOIS and IDENTIFY to send the request to router
1365 if normal server did not do it and did not find any results.
1367 Affected file silcd/command.c.
1369 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1371 * Moved the internal data from SilcClient context into its
1372 own file, not accesible to application. Affected files
1373 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1374 and other files in client library.
1376 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1378 * Added doc/examples installation target in Makefile.am.pre.
1381 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1383 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1384 commands the found client entry will be removed from the
1385 cache, after notifying application about the error. Affected
1386 file lib/silcclient/command_reply.c.
1388 * Changed the /MSG to check for exact nickname user gave, and
1389 not let `nick' match `nick@host' if it is only one found. Now,
1390 user must type the exact nickname (like nick@host2) even if
1391 there are no more than one same nicks found. This is to avoid
1392 a possibility of sending nickname to wrong nickname since
1393 `nick' could match `nick@host'. Affected file is
1394 irssi/src/core/silc-servers.c.
1396 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1398 * Do not print "you are now server operator" or similar when
1399 giving /away command. Affected files are
1400 irssi/src/silc/core/client_ops.c, silc-servers.h.
1402 * Made the silc_server_command_pending_error_check to send
1403 the same command reply payload it received back to the
1404 original sender of the command. This way all arguments
1405 that was received by the server will be received by the
1406 client too. Affected file silcd/command.c.
1408 * Added the silc_idcache_add to return the created cache entry
1409 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1411 * Add global clients to expire if they are not on any channel.
1412 This is because normal server will never know if they signoff
1413 if they are not on any channel. The cache expiry will take
1414 case of these entries. This is done by normal servers only.
1415 The affected files are silcd/command_reply.c,
1416 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1418 * If server receives invalid ID notification for WHOIS or
1419 IDENTIFY and the ID exists in the lists, it is removed.
1420 Affected file silcd/command_reply.c.
1422 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1423 in client then client entry that it matches is searched and
1424 the nickname is printed on the screen for user. Affected
1425 file irssi/src/silc/core/client_ops.c.
1427 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1429 * Use cache entry expire time in the LIST command reply to
1430 purge old entries from the cache after the LIST command
1431 reply has been received. This way we don't have non-existent
1432 entries in the cache for too long. Affected file is
1433 silcd/command_reply.c.
1435 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1437 * If we are normal server, and we've not resolved client info
1438 in WHOIS or IDENTIFY from router, and it is global client,
1439 we'll check whether it is on some channel. If it is not
1440 then we cannot be sure about its validity and will resolve it
1441 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1442 file silcd/command.c.
1444 * Search channel by name (if possible) rather than by ID
1445 in IDENTIFY command's command reply. Affected file is
1446 silcd/command_reply.c.
1448 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1450 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1451 Updated specs and implemented it. Affected file silcd/command.c,
1452 silcd/packet_send.c and silcd/packet_receive.c.
1454 * Implemented the <founder auth> payload handling in the JOIN
1455 command. If provided all conditions for channel joining
1456 except requirement to provide correct passphrase can be
1457 overrided by the channel founder. Updated the protocol specs.
1458 Affected file silcd/command.c.
1460 Added support for founder auth in JOIN command in client
1461 library. Fixed the parsing of the JOIN command now to support
1462 all options as they should be. The affected file is
1463 lib/silcclient/command.c.
1465 * Optimized the WHOIS and IDENTIFY commands to send the request
1466 to router only if it includes nicknames or other names. If
1467 they include only IDs then check the local cache first before
1468 routing. Affected file is silcd/command.c.
1470 * Added channels topic announcements. Affected file is
1471 silcd/packet_receive.c and silcd/server.c.
1473 * Fixed the silc_server_send_notify_topic_set to really destine
1474 the packet to channel. Affected file silcd/packet_send.c.
1476 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1477 library. Affected file lib/silcclient/client_notify.c.
1479 * Added UMODE announcements. Affected file silcd/server.c.
1481 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1483 * Memory leak fixes in:
1485 lib/silcutil/silcsockconn.c
1486 lib/silcske/silcske.c
1487 lib/silcske/groups.c
1489 lib/silccrypt/silcpkcs.c
1490 lib/silccore/silccommand.c
1491 lib/silccore/silcidcache.c
1496 * ROBOdoc documented the lib/silcske/groups.h file and a
1497 bit changed the interface for better.
1499 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1501 * Update the client entry context in the ID cache after
1502 nick change. Affected file lib/silcclient/command.c.
1503 Fixes the CUMODE command when regaining founder privileges,
1504 and a little WHOIS problem.
1506 * Fixed silc_net_gethostbyname to correctly call the
1507 inet_ntop. Affected file lib/silcutil/silcnet.c.
1509 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1511 * Added IPv6 support checking to the configure.in.pre, added
1512 also --enable-ipv6 option to override the check. Affected
1513 file configure.in.pre.
1515 * The silc_thread_create now calls the start function
1516 directly if threads support is not compiled in. Removes
1517 ugly #ifdef's from generic code. Affected files are
1518 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1520 * Added silc_net_gethostby[name/addr]_async to asynchronously
1521 resolve. Affected files are lib/silcutil/silcnet.[ch].
1523 * Added support for rendering IPv6 based server, client and
1524 channel IDs. Affected file lib/silcutil/silcutil.c.
1526 * Added support for creating IPv6 based server IDs. Affected
1527 file is silcd/serverid.c.
1529 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1531 * Added silc_net_gethostby[addr/name] into the
1532 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1533 routines. Added silc_net_is_ip[4/6]. Affected file is
1534 lib/silcutil/unix/silcunixnet.c. All routines that take
1535 address as argument now supports both IPv4 and IPv6 addresses.
1537 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1539 * Fixed LIST command reply sending in server. Affected file
1542 * Server now sends the kicker's client ID in the KICK notify
1543 to the kicked client. Affected file silcd/command.c.
1545 * The client library now parses the kickers client ID and
1546 UI displays it. Affected files lib/silcclient/client_notify.c
1547 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1549 * Made all payload parsing function prototypes consistent.
1550 They all take now const unsigned char * and uint32 pair as
1551 the payload data instead of SilcBuffer. Changes all around
1552 the source tree. Other unsigned char* -> const unsigned char*
1553 changes around the tree as well.
1555 * Optimized SFTP client and server packet sending not to
1556 allocate new buffer for each packet but to recycle the
1557 first allocated buffer. Affected files are
1558 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1560 * Optimized the SFTP client to use SilcList instead of
1561 SilcDList for requests, because it is faster. Affected file
1562 is lib/silcsftp/sftp_client.c.
1564 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1565 into lib/silccore/silcid.[ch].
1567 Renamed silcpayload.[ch] into silcargument.[ch].
1569 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1571 * If client entry is deleted with active key agreement
1572 session, abort the session.
1574 The silc_client_abort_key_agreement now calls the completion
1575 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1577 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1580 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1582 * Don't use __restrict in older GCC's. Affected file is
1583 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1585 * silc_net_localhost now attempts to reverse lookup the
1586 IP/hostname. Affected file lib/silcutil/silcnet.c.
1588 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1589 command. It can be used to gain founder privileges at
1590 the same time when joining the channel.
1592 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1593 kicker's client ID as well. Updated protocol specs.
1595 Defined that the server must send SILC_COMMAND_IDENTIFY
1596 command reply with error status to client who sent
1597 private message with invalid client ID.
1599 Updated the protocol specification.
1601 * Added silc_server_send_command_reply to send any
1602 command reply. Affected file silcd/packet_send.[ch].
1604 * Added silc_id_payload_encode_data to encode ID payload
1605 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1607 * The server now send IDENTIFY command reply with error
1608 status if client ID in private message is invalid. Affected
1609 file silcd/packet_receive.c.
1611 * Save the server key file with server's IP address in
1612 the filename instead of hostname. The affected file is
1613 irssi/src/silc/core/client_ops.c.
1615 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1617 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1620 * Added libtool support for compiling shared objects in
1621 lib/silcsim. Affected file configure.in.pre and
1622 lib/silcsim/Makefile.am. Original patch by cras.
1624 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1626 * Pid file configuration, and server's config file fixes
1627 patch by toma. Updated CREDITS file.
1629 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1631 * Fixed silc_client_channel_message to not try to decrypt
1632 the message twice if it resolved the destination client
1633 information. This could cause of dropping one channel
1634 message. Affected file lib/silcclient/client_channel.c.
1636 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1638 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1639 lib/silcclient/client.c. This function is used when the SILC
1640 Client is run under some other scheduler, or event loop or
1641 main loop. On GUI applications, for example this may be
1642 desired to used to run the client under the GUI application's
1643 main loop. Typically the GUI application would register an
1644 idle task that calls this function multiple times in a second
1645 to quickly process the SILC specific data.
1647 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1649 * Fixed silc_server_drop() for dropping the supplementary
1650 groups as well, this could cause a security hole on some
1653 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1655 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1658 * Write PID file after dropping privileges. Added -F option
1659 to run server on foreground. A patch by debolaz.
1660 Affected files silcd/server.c, silcd/silcd.c.
1662 * Fixed MOTD to return the MOTD file server name. Affected
1663 file silcd/command.c.
1665 * Added INFO command reply handling to the Irssi SILC Client.
1666 Affected file irssi/src/silc/core/client_ops.c.
1668 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1670 * Fixed the silc_idcache_list_* routines to really support
1671 the dynamic list. Fixes a crash. Affected file is
1672 lib/silccore/silcidcache.c.
1674 * Fixed the LIST command reply to really call LIST command's
1675 pending callbacks. Affected file silcd/command_reply.c.
1677 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1679 * Update conn->local_entry->nickname after giving NICK
1680 command. Affected file lib/silcclient/command.c.
1682 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1684 * Added the [pid] option to the silcd configuration file
1686 Affected files: serverconfig.[ch] and silcd.c
1688 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1690 * Save fingerprint in WHOIS command reply in server.
1691 Affected file silcd/command_reply.c.
1693 * Fixed NICK commands pending callback registration.
1694 Affected file lib/silcclient/command.c.
1696 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1698 * Use ++server->cmd_ident when sending commands in server,
1699 instead of random number. Affected file silcd/command.c.
1701 * Fixed GETKEY command reply to call actually GETKEY pending
1702 command callbacks. Affected file silcd/command_reply.c.
1704 * A bit stricter check for nicknames. Check for same nickname
1705 in NICK command also. Affected file silcd/command.c.
1707 * Do not call INFO command everytime client ID changes, only
1708 during first connecting. Affected file lib/silcclient/client.c.
1710 * Set the new nickname only after successful command reply for
1711 NICK command is returned by server. Affected file
1712 lib/silcclient/command.c.
1714 * Remove nicknames from nicklist during server_signoff notify.
1715 Should fix /NAMES bit more. The affected file is
1716 irssi/src/silc/core/silc-channels.c.
1718 * Added `fingerprint' field to the SilcIDListData in the
1719 silcd/idlist.h to hold the fingerprint of the client's
1722 Send the fingerprint of the client's public key in WHOIS
1725 Affected files silcd/command.c, and silcd/idlist.[ch].
1727 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1728 create fingerprint from given data.
1730 * Show the fingerprint of the client's public key in WHOIS.
1731 Affected files irssi/src/module-formats.[ch] and
1732 irssi/src/silc/core/client_ops.c.
1734 * Format the multiple same nicknames also during JOIN and
1735 NICK_CHANGE notifys. Affected file is
1736 lib/silcclient/client_notify.c.
1738 * Do not print error on screen for invalid private message
1739 payload since it can come if someone is sending private
1740 messages with wrong key. Affected file
1741 lib/silccore/silcprivate.c.
1743 * Fixed multiple concurrent /PING crash. Affected file
1744 lib/silcclient/command.c.
1746 * Changed the wrong ID encoding. All IP addresses must be
1747 in MSB first order in encoded format. They were encoded
1748 wrong and was in LSB format. Affected files are
1749 silcd/serverid.c, lib/silcutil/silcutil.c.
1751 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1753 * Call the `connect' client operation through the scheduler
1754 in case of error. Affected file lib/silcclient/client.c.
1756 * Call the `failure' client operation even if the error
1757 occurred locally during a protocol. Affected file is
1758 lib/silcclient/protocol.c.
1760 * Added support of sending LIST command to router from normal
1761 server. This way normal server can get list of all channels
1762 in the network too. Fixed the channel list sending in the
1763 server too. Affected files are silcd/command.c, and
1764 silcd/command_reply.[ch].
1766 * Added silc_server_update_channels_by_server and
1767 silc_server_remove_channels_by_server. They are used during
1768 disconnection of primary router and in backup router protocol.
1769 Affected file silcd/server_util.[ch], silcd/server.c and
1770 silcd/server_backup.c.
1772 * Fixed channel adding to global list in IDENTIFY command
1773 reply in server. Affected file silcd/command_reply.c.
1775 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1777 * If the incoming packet type is REKEY or REKEY_DONE process
1778 that packet always synchronously. Fixes yet another MAC
1779 failed error on slow (dialup) connections. Affected file
1780 lib/silcclient/client.c and silcd/server.c.
1782 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1784 * Call check_version SKE callback for initiator too. Affected
1785 file lib/silcske/silcske.c.
1787 * Implemented fix for security hole found in the SKE that was
1788 fixed in the specification few days back; the initiator's
1789 public key is now added to the HASH value computation.
1790 Added backwards support for the old way of doing it too, for
1791 old clients and old servers. Affected file is
1792 lib/silcske/silcske.c.
1794 * Enabled mutual authentication by default in SKE. If initiator
1795 is not providing mutual authentication the responder will
1796 force it. This will provide the proof of posession of the
1797 private key for responder. The affected files are
1798 lib/silcclient/protocol.c and silcd/protocol.c.
1800 * Do not cache anymore the server's public key during SKE.
1801 We do mutual authentication so the proof of posession of
1802 private key is done, and if the server is authenticated in
1803 conn auth protocol with public key we must have the public
1804 key already. Affected file silcd/protocol.c.
1806 * Added new global debug variable: silc_debug_hexdump. If
1807 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1808 file lib/silcutil/silclog.[ch].
1810 * Fixed compilation warning due to char * -> const char *.
1811 Affected files lib/silcutil/silcnet.h, and
1812 lib/silccore/silcauth.[ch].
1814 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1816 * Fixed CMODE command when new channel key was created. If
1817 the creation failed the old key was removed. Next time giving
1818 same command would crash the server since the old key was
1819 freed already. Affected file silcd/command.c.
1821 * Fixed the silc_server_announce_get_channels to not crash
1822 on reconnect. Affected file silcd/server.c.
1824 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1826 * Added silc_log_set_debug_string function to set a regex
1827 string to match for debug output. Only the function names,
1828 or filenames matching the given debug string is actually
1829 printed. This way it is possible to filter out those debug
1830 strings that user is not interested in.
1832 Fixed a bug in silc_string_regexify.
1834 Affected files lib/silcutil/silclog.[ch], and
1835 lib/silcutil/unix/silcunixutil.c.
1837 * Changed the -d options in both server and Irssi SILC client
1838 to take the debug string as argument. Affected files
1839 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1841 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1843 * Added silc_hash_babbleprint to create a Bubble Babble
1844 Encoded fingerprint. The encoding is developed by Antti
1845 Huima (draft-huima-babble-01.txt), and it creates human
1846 readable strings out of binary data. Affected file
1847 lib/silccrypt/silchash.[ch].
1849 * Print the babble print now in addition of fingerprint as well
1850 in Irssi SILC client. Affected files are
1851 irssi/src/fe-common/silc/module-formats.[ch],
1852 irssi/src/fe-common/silc/core/client_ops.c.
1854 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Fixed a security problem found in SKE. The initiator's
1857 public key too is now added to the HASH hash value creation
1858 which is signed by the responder to create the SIGN value.
1859 This will prevent anyone in the middle to lie to the responder
1860 about the initiator's public key. If this is done now, the
1861 man in the middle will get caught. Updated the protocol
1864 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1866 * Better installation directory handling. Configure module
1867 paths and other paths automatically to example_silc* files
1868 in doc/. A patch by toma.
1870 * Fixed compiler warning from MPI library, and from SILC RNG.
1873 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1874 It can be configured with ./configure. A patch by toma.
1876 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1878 * Find correct make to use in prepare-clean. A patch by
1879 toma. Affected file prepare-clean.
1881 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1883 * Added irssi variables use_auto_addr, auto_bind_ip,
1884 auto_bind_port and auto_public_ip.
1886 * Changed the interface for silc_client_send_key_agreement
1887 in lib/silcclient/silcapi.h
1891 irssi/src/silc/core/silc-core.c
1893 lib/silcclient/silcapi.h
1894 irssi/src/silc/core/silc-channels.c
1895 lib/silcclient/client_keyagr.c
1898 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1900 * Added silc_pkcs_public_key_compare to compare two
1901 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1903 * Check that the client who set the founder mode on the
1904 channel is the same client that is giving the founder
1905 mode to itself. It is done by comparing the saved public
1906 key (it is saved even in the authentication is passphrase).
1907 Affected file silcd/command.c.
1909 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1911 * Do not process packet for disconnected socket connection.
1912 Affected file lib/silccore/silcpacket.c.
1914 * Process the DISCONNECT packet through scheduler in the
1915 client library. Affected file lib/silcclient/client.c.
1917 * Fixed the silc_client_packet_parse to not to increase
1918 the packet sequence number if the conn->sock and the
1919 current socket connection is not same. This can happen
1920 for example during key agreement when the conn includes
1921 multiple socket connections (listeners). Affected file
1922 lib/silcclient/client.c.
1924 * The sender of the file transfer request now provides also
1925 the pointer (listener) for the key exchange protocol. If
1926 the listener cannot be created then it sends empty key
1927 agreement and lets the receiver provide the listener.
1929 Added `local_ip' and `local_port' arguments to the
1930 silc_client_file_send. If they are provided they are used,
1931 if not then it will attempt to find local IP address, if
1932 not found or bind fails then the remote client will provide
1935 Affected files are lib/silcclient/client_ftp.c and
1936 lib/silcclient/silcapi.h.
1938 * Extended the FILE SEND command to support defining the
1939 local IP and port for key exchange listener. They are
1940 optional. Affected file irssi/src/silc/core/silc-servers.c.
1942 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1944 * Defined to WHOIS command reply the sending of fingerprint
1945 of the client's public key (if the proof of posession of the
1946 corresponding private key is verified by the server).
1947 Updated to the protocol specification.
1949 * Added support of receiving the client's public key's
1950 fingerprint in command reply in client library. Affected
1951 file is lib/silcclient/command_reply.c, and
1952 lib/silcclient/idlist.[ch].
1954 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1956 * Do not send over 128 chars long nickname to the server
1957 in NICK command. Affected file lib/silcclient/command.c.
1959 * Do not send over 256 chars long channel names to the server
1960 in JOIN command. Affected file lib/silcclient/command.c.
1962 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1964 * Assure that silc_server_close_connection cannot be called
1965 twice for same socket context. Affected file is
1968 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1970 * Send error message to application if opening file for
1971 writing during file transfer fails. Affected file is
1972 lib/silcclient/client_ftp.c.
1974 Remove all file transfer sessions for a client that we're
1975 removing from ID cache.
1977 Affected file is lib/silcclient/client_ftp.c.
1979 * Fixed silc_net_addr2bin to return correct address. Affected
1980 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1982 * Fixed file transfer session removing on signoff notify.
1983 Affected file irssi/src/silc/core/silc-servers.c.
1985 * Added the SilcClientFileError to be returned in the monitor
1986 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1987 Affected file lib/silcclient/silcapi.h.
1989 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1991 * Fixed a crash in silc_client_ftp_free_sessions and
1992 silc_client_ftp_session_free_client. Affected file
1993 lib/silcclient/client_ftp.c.
1995 * Added `disabled' field in the SilcChannelEntry in the server
1996 to indicate if the server entry is disabled. Affected file
1997 silcd/idlist.h, silcd/command[_reply].c.
1999 * SILC server adds now /var/run/silcd.pid everytime it is
2000 started. Affected file silcd/silcd.c.
2002 * Added silc_server_packet_send_clients to send a packet to
2003 the provided table of client entries. Affected file
2004 silcd/packet_send.[ch].
2006 * Fixed a crash in client resolving in client_prvmsg.c in
2007 client library. Affected file lib/silcclient/client_prvmsg.c.
2009 * Do not actually remove the client directly from ID cache
2010 during SERVER_SIGNOFF, but invalidate it. This way we
2011 preserve the WHOWAS info for the client. Affected file
2012 silcd/server_util.c.
2014 * Fixed SERVER_SIGNOFF notify handling in the server. The
2015 server is now able to process incoming SERVER_SIGNOFF notify
2016 for a server that it doesn't even know about. It will remove
2017 the clients provided in the notify. Affected file
2018 silcd/packet_receive.c.
2020 * Check for partial packet in data queue after every packet that
2021 was found from the queue. Return and wait for more data if
2022 there is partial data in queue. Affected file is
2023 lib/silccore/silcpacket.c.
2025 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2027 * Added SilcClietFileError enum to indicate error in
2028 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2029 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2030 Affected files lib/silcclient/silcapi.h and
2031 lib/silcclient/client_ftp.c.
2033 * Check that newsize in silc_buffer_realloc is larger than
2034 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2036 * Added better monitor of file transfers. It now monitors
2037 key agreement protocol during the file transfer too. Added
2038 error reporting too. Affected files
2039 irssi/src/silc/core/silc-servers.c,
2040 irssi/src/fe-common/silc/module-formats.[ch].
2042 * Wrote a help file for FILE command.
2044 * Added silc_rng_global_get_byte_fast to get not-so-secure
2045 random data as fast as possible. Random data is read from
2046 /dev/urandom if available and from the SILC RNG if not
2047 available. It is used in padding generation. Affected file
2048 lib/silccrypt/silcrng.[ch].
2050 * All packets in client library are now processed synchronously.
2051 Optimized packet processing a lot. Affected file
2052 lib/silcclient/client.c.
2054 * All server connection packets are processing synchronously
2055 now in server, to optimize packet processing. Affected file
2058 * Include files are installed now only in Toolkit distribution
2059 if make install is given. Affected files: all Makefile.am's.
2061 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2063 * Assure that silc_client_notify_by_server_resolve does not
2064 resolve the client information multiple times. If it cannot
2065 be found by the first it cannot be found at all. Affected
2066 file lib/silcclient/client_notify.c.
2068 * Fixed WHOWAS command reply calling. Affected file
2069 lib/silcclient/command_reply.c.
2071 * Removed all references to silc_idlist_get_client from the
2072 Irssi SILC client since that call is internal call used by
2073 the library. The Irssi SILC client will use now client
2074 retrieval functions found in silcapi.h.
2076 * Fixed a bug in resolving nickname info before sending
2077 private message. It used freed memory. Affected file
2078 irssi/src/silc/core/silc-servers.c.
2080 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2082 * Assure my_channels statistics cannot go negative in server.
2083 Affected files silcd/server.c, silcd/server_util.c.
2085 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2087 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2089 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * Win32 Toolkit changes. Affected files
2092 win32/silc.dsw, win32/libsilc/libsilc.def,
2093 win32/libsilcclient/libsilc.def,
2094 lib/silcutil/silcutil.c, and
2095 lib/sftp/sftp_fs_memory.c.
2097 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2099 * Added silc_net_localip to return local host's IP address.
2100 Affected file lib/silcutil/silcnet.[ch].
2102 * If key exchange or rekey protocol is active for a connection
2103 parse all packets syncronously since there might be packets
2104 in packet queue that we are not able to process without first
2105 processing packets before them. Affected file silcd/server,
2106 lib/silcclient/client.c.
2108 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2109 whether library should continue processing the packet.
2110 Affected file lib/silccore/silcpacket.h.
2112 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2113 SilcSFTPMonitorData to SFTP server to monitor various
2114 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

2122 transmission. Affected file lib/silcclient/client_ftp.c,
2123 lib/silccilent/client.[ch].
2125 * Added new local command FILE to the Irssi SILC Client.
2126 It is used to perform the file transfer. It has subcommands
2127 SEND, RECEIVE, SHOW and CLOSE. Affected files
2128 irssi/src/silc/core/client_ops.c,
2129 irssi/src/silc/core/silc-server.[ch].
2131 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2133 * Relay the SILC_PACKET_FTP in the server. Affected files
2134 silcd/server.c and silcd/packet_receive.c.
2136 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2138 * Renamed silc_file_read and silc_file_write to functions
2139 silc_file_readfile and silc_file_writefile. Added function
2140 silc_file_open and silc_file_close. Affected files
2141 lib/silcutil/silcutil.[ch].
2143 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2145 * Resolve the client info when received private message or
2146 channel message for a client which nickname we don't know.
2147 Affected files lib/silcclient/client_prvmsg.c and
2148 lib/silcclient/client_channel.c.
2150 * Do not crash in /KEY if client is not connected. Affected
2151 file irssi/src/silc/core/silc-channels.c.
2153 * Added SilcClientStatus field to the SilcClientEntry in the
2154 lib/silcclient/idlist.h.
2156 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2157 is incomplete and is being resolved, it won't be resolved
2160 Make sure also that USERS command reply does not resolve
2161 twice information. Affected file is
2162 lib/silcclient/command_reply.c.
2164 Make sure that silc_client_get_clients_by_list does not
2165 resolve twice same information.
2167 * Check for valid client->id in the silc_server_free_client_data.
2168 Affected file silcd/server.c.
2170 * Fixed /GETKEY nick@server not to crash if the server entry
2171 is not found. Affected file lib/silcclient/command.c.
2173 * Fixed the silc_server_check_cmode_rights to check the
2174 requested modes correctly. Affected file silcd/command.c.
2176 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2178 * Better checks for non-printable chars in nick added.
2179 Affected file silcd/command.c.
2181 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2183 * Call the silc_server_udpate_servers_by_server in the
2184 primary router that comes back online in the backup resuming
2185 protocol. Otherwise it routes packets wrong. Affected file
2186 silcd/server_util.[ch], silcd/server_backup.c.
2188 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2191 lib/silcutil/silcbuffmt.[ch].
2193 * Redefined the SILC packet header to include the padding
2194 length. Affected file lib/silccore/silcpacket.[ch].
2196 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2197 length for maximum padding up to 128 bytes). Affected
2198 file lib/silccore/silcpacket.h.
2200 * Removed all backwards support for old 0.5.x MAC thingies.
2201 The SILC packet header change makes it impossible to be
2202 backwards compatible.
2204 * Send the ENDING packet with timeout in the backup resuming
2205 protocol. This is to assure that all routers has connected
2206 to the primary router. Affected file silcd/server_backup.c.
2208 * Changed the RNG to take the first IV from random data. It
2209 used to take it from zero actually. Changed the RNG also
2210 to use /dev/urandom during session. /dev/random is used
2211 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2213 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2215 * Changed the SILC packet header to have the first two bytes
2216 (the packet length) encrypted. Affected files aroung the
2217 code tree, lib/silccore/silcpacket.[ch]. Removed the
2218 SilcPacketCheckDecrypt callback. It is not needed anymore
2219 since the silc_packet_receive_process will determine now
2220 whether the packet is normal or special.
2222 * Implemented the unidirectional MAC keys. Affected files
2223 lib/silcske/silcske.c, silcd/protocol.c and
2224 lib/silcclient/protocol.c.
2226 * Implemented the packet sequence number to the MAC computation.
2227 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2228 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2229 lib/silcclient/protocol.c.
2231 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2233 * Allow backup router to announce servers. All servers
2234 announced by backup router are added to the global list
2235 automatically. Update hte server's socket to our primary
2236 router also when backup router announces a server.
2237 Affected file silcd/packet_receive.c.
2239 * Do not update the client->router in the function
2240 silc_server_udpate_clients_by_server if the client is on
2241 global list. We might fail to find any specific server
2242 for locally connected clients and local cell clients. They
2243 should still use the `from' and not `to' as client->router.
2244 This fixes backup router resuming protocol. Affected file
2245 silcd/server_util.c.
2247 * Decrease channel statistics count only if the channel
2248 deletion worked. Affected files are silcd/server.c and
2249 silcd/server_util.c.
2251 * Added silc_server_update_servers_by_server to update origin
2252 of all server entries. Used during backup router protocol.
2253 Affected files silcd/server_util.[ch], silcd/server.c. and
2254 silcd/backup_router.c.
2256 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2257 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2258 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2259 lib/silccrypt/silchmac.c.
2261 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2263 * Assure that router cannot reroute the same channel message
2264 to the sender. Affected file silcd/packet_receive.c.
2266 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2268 * Made better checks that the channel message is not sent
2269 to the router it came from. Affected file is
2270 silcd/packet_send.c. Fixed memory leak too.
2272 * Announce informations for incoming router connection, but
2273 only after checking if it is replaced by backup router.
2274 Affected file silcd/packet_receive.c.
2276 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2278 * Fixed the backup resuming protocol to work in multiple
2279 router environment. Affected file silcd/server_backup.c.
2281 * Route packet only to one router in the function
2282 silc_server_packet_send_to_channel. Affected file is
2283 silcd/packet_send.c.
2285 * Fixed silc_server_send_notify_dest to set the broadcast
2286 flag. Fixed the silc_server_send_notify_topic to actually
2287 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2288 Affected file silcd/packet_send.c.
2290 * Changed the SFTP Filesystem interface. Changed the
2291 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2292 the filesystem operation function. The SilcSFTPFilesystem
2293 is now a context that is allocated by all filesystem allocation
2294 functions and it already includes the operations structure
2295 and filesystem specific context. It is given as argument
2296 now to the silc_sftp_server_start. This made the interface
2297 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2298 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2300 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2302 * Changed the backup router adding and getting interfaces
2303 in the server. The router that will be replaced by the
2304 specified backup router is now sent as argument. Affected
2305 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2308 * Added silc_net_addr2bin_ne to return the binary form of
2309 the IP address in network byte order. Affected files
2310 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2312 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Check for existing server ID in silc_server_new_server
2315 and in silc_server_connect_to_router_final and remove the
2316 old entry if it exists. Affected file silcd/packet_receive.c,
2319 * Send the channel message always to only one router, either
2320 in upstream or downstream. Affected file is
2321 silcd/packet_send.c.
2323 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2325 * Wrote the definition of the backup resuming protocol to the
2326 protocol specification.
2328 * Removed one redundant channel key generation from normal
2329 server during joining procedure. Removed one redundant
2330 channel key sending from server to router during joining
2331 procedure. Affected file silcd/command.c.
2333 * Made minor bugfixes to the backup router resuming protocol.
2334 Affected file silcd/server_backup.c, server.c.
2336 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2338 * Added --disable-asm configuration option. Affected files
2339 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2342 * Implemented the backup resuming protocol that is used to
2343 resume the primary router position in the cell after the
2344 primary router comes back online. Affected files
2345 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2346 and silcd/server_util.[ch].
2348 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2350 * Sleep two (2) seconds after sending QUIT command to server.
2351 Affected file lib/silcclient/command.c.
2353 * Assure that if outgoing data buffer is pending do not force
2354 send any data. Affected file silcd/packet_send.c.
2356 * Assure that if outgoing data buffer is pending do not force
2357 send any data. Affected file lib/silcclient/client.c.
2359 * Implemented the backup router support when the primary router
2360 goes down. The servers and routers can now use the backup
2361 router as new primary router without loosing connectivity.
2363 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2365 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2366 in the server to indicate disabled entry. All data read
2367 from the connection will be ignored and no data is sent
2368 for entry that is disabled. Affected files are
2369 silcd/idlist.h, silcd/server.c.
2371 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2373 * Created SFTP client and server test programs in the
2374 lib/silcsftp/tests directory.
2376 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2378 * Implemented memory filesystem (virtual filesystem) for
2379 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2382 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2384 * Implemented the SFTP (SSH File Transfer Protocol) to the
2385 lib/silcsftp. It includes SFTP client and SFTP server
2388 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2390 * Moved lib/silccore/silcprotocol.[ch] to the
2391 lib/silcutil library.
2393 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2394 take variable argument list pointer as argument. Affected
2395 file lib/silcutil/silcbuffmt.[ch].
2397 * Added silc_buffer_set function that is used to set data
2398 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2399 Affected file lib/silcutil/silcbuffer.h.
2401 * Changed various routines in the core library to use the new
2402 silc_buffer_set instead of allocating new buffer only for
2405 * Added 64-bit value formatting and unformatting support to the
2406 silc_buffer_[un]format routines. Affected file is
2407 lib/silcutil/silcbuffmt.[ch].
2409 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2410 to includes/bitmove.h.
2412 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2414 * Fixed channel user mode saving in client library. Affected
2415 file lib/silcclient/command[_reply].c.
2417 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2419 * Defined the file transfer to the SILC Protocol. Added
2420 new packet type SILC_PACKET_FTP and defined File Transfer
2421 Payload. The mandatory file transfer protocol is SFTP
2422 (SSH File Transfer Protocol). Affected file in addition
2423 of the internet draft is lib/silccore/silcpacket.h.
2425 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2426 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2427 is used as part of backup router protocol when the primary
2428 router of the cell is back online and wishes to resume
2429 the position as primary router.
2431 * Redefined the MAC generation keys in the protocol. The
2432 same key is not used anymore in both direction. Both
2433 direction will now use different keys for sending and
2434 receiving. This fixes a potential security flaw. This
2435 change causes incompatibilities in the protocol.
2437 * Redefined also the MAC computation from the packet.
2438 An packet sequence number is now added to the MAC
2439 computation. This prevents possible replay attacks against
2440 the protocol. This change too causes incompatibilities
2443 Added `sequence' field to the SilcPacketContext to hold
2444 the current sequence number for the packet.
2446 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2448 * Added `created' field to the SilcIDListData in the file
2449 silcd/idlist.h to indicate the time when the entry was
2452 * Added `created' field to the SilcChannelEntry too. Affected
2453 file silcd/idlist.h.
2455 * Added `creation_time' aguments to all the announcement functions
2456 in the server. If it is provided then only the entries that
2457 was created after the provided time frame are actually
2458 announced. Affected file silcd/server.[ch].
2460 * The protocol says that the Channel ID's IP address must be
2461 based on the router's IP address. Added check for this in
2462 the silc_server_new_channel when processing incoming New Channel
2463 Payload. Affected file silcd/packet_receive.c.
2465 * Print out the correct version with --version in SILC client.
2466 Affected file irssi/src/silc/core/silc-core.c.
2468 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2470 * Fixed WHOWAS command to check for completnes of the client
2471 entry always, not just when the command is coming from client.
2472 Affected file silcd/command.c.
2474 * Added new function silc_server_packet_queue_purge to purge the
2475 outgoing data queue to the network. After the function returns
2476 it is guaranteed that the outgoing packet queue is empty.
2477 Affected file silcd/packet_send.[ch].
2479 * Purge the outgoing packet queue in the rekey protocol's final
2480 callback to assure that all rekey packets go to the network
2481 before quitting the protocol. Affected file silcd/server.c.
2483 * Added silc_client_packet_queue_parse as similar function as
2484 in server to the client library. The affected file is
2485 lib/silcclient/client.c.
2487 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * Splitted silcd/server.c and created silcd/server_util.[ch]
2490 for utility functions.
2492 * Added new socket flag SILC_SF_DISABLED to indicate that the
2493 connection is open but nothing can be sent to or received from
2494 the connection. Affected file lib/silcutil/silsockconn.[ch].
2495 The checking for disabled socket is checked in the low level
2496 silc_socket_write and silc_socket_read functions.
2498 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2500 * Allow only nicknames and channel names that fits into the
2501 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2503 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2505 * When processing JOIN command reply in server check that if
2506 the channel exists in our global list we'll move it the local
2507 list. Affected file silcd/command_reply.c.
2509 * Fixed the check whether client is joined on the channel already
2510 in JOIN command. Affected file lib/silcclient/command.c.
2512 * Fixed the JOIN command reply to check whether the channel
2513 already exists. Affected file lib/silcclient/command_reply.c.
2515 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2517 * Added silc_ske_status_string to map the SKE error numbers
2518 to readable strings. The affected files are
2519 lib/silcske/silcske[_status].[ch].
2521 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2523 * Do not show the private channels on the WHOIS channel list
2524 as it is not allowed by the protocol. The affected file is
2527 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2529 * Assure that the packet length digged from the actual packet
2530 is something sensible in the silc_packet_decrypt_rest_special
2531 in lib/silccrypt/silcpacket.c.
2533 * Free and NULL the allocated pointer in silc_hmac_alloc if
2534 the HMAC allocation fails. The affected file is
2535 lib/silccrypt/silchmac.c.
2537 * Print the selected security properties to the log files in
2538 the server. Affected file silcd/protocol.c.
2540 * Add SKE's reference counter even if calling the completion
2541 callback manually. Otherwise it goes negative, although it
2542 does not cause any problems. The affected file is
2543 lib/silcske/silcske.c.
2545 * Remove the client entry with short timeout after giving the
2546 KILL command. Affected file lib/silcclient/command.c.
2548 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2549 case all found clients are already disconnected (WHOWAS would
2550 found them) in the server. Affected file silcd/command.c.
2552 * Update the last_receive (time of last data received) to be
2553 updated only when received private or channel message so that
2554 the idle time showed in WHOIS makes more sense.
2556 * Added boolean field `valid' in to the SilcClientEntry in the
2557 client library to indicate whether the entry is valid or not.
2558 This fixes the nickname change bug on channel when changing
2559 the nickname to be same than the old (like nick to Nick) the
2560 nickname formatter doesn't set the new nick anymore to Nick@host.
2561 Affected file lib/silcclient/idlist.[ch].
2563 * Now actually fixed the nickname changing on disconnection.
2564 Added new function silc_change_nick to the Irssi SILC Client.
2565 Affected file irssi/src/silc/core/client_ops.c,
2566 irssi/src/silc/core/silc-nicklist.[ch].
2568 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Check that the public key exists in the GETKEY command before
2571 trying to encode it. Affected file silcd/command.c.
2573 * Print some notifications on received public keys with GETKEY
2574 command in the Irssi SILC Client. Affected files are
2575 irssi/src/fe-common/silc/module-formats.[ch],
2576 irssi/src/silc/core/client_ops.c.
2578 * Use IDENTIFY command to resolve the server information in the
2579 GETKEY command instead of INFO command. Affected file
2580 lib/silcclient/command.c.
2582 * All command reply functions in the client library now calls
2583 the pending command reply callbacks even if an error has
2584 occurred. The server has done this a long time and now it was
2585 time to move the client library to this as well. Now all
2586 errors can be delivered back to the pending command reply
2587 callbacks if necessary. Affected files are
2588 lib/silcclient/command[_reply].[ch].
2590 * Change the nickname on disconnection back to the username
2591 because in reconnect the server will enforce it to it anyway.
2592 Affected file irssi/src/silc/core/silc-servers.c.
2594 * Fixed a config file parsing bug in the Irssi SILC client.
2595 Affected file irssi/src/silc/core/clientconfig.c.
2597 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2599 * When printing the channel mode on JOIN, verify that the
2600 channel key and channel's HMAC are valid. Affected file
2601 irssi/src/silc/core/client_ops.c.
2603 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2606 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2607 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2609 * Removed channel key rekey task deleting from the function
2610 silc_server_save_channel_key. Affected file silcd/server.c.
2611 Added explicit timeout task context instead that is used to
2612 delete the task if we are registering a new task before the
2613 new task has elapsed.
2615 * When channel key rekey occurs the client library now saves
2616 the old channel key for a short period of time (10 seconds) and
2617 is able to use it in case some is still sending channel
2618 messages encrypted with the old key after the rekey. Affected
2619 file lib/silcclient/[idlist.h|client_channel.c].
2621 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2623 * Added check to the silc_server_new_id_real to not accept
2624 new ID if it is the sender's own ID. Affected file is
2625 silcd/packet_receive.c.
2627 * Assure that we do not announce ourself or the one we've
2628 sending our announcements when we're router and are announcing
2629 servers to our primary router. Affected file silcd/server.c.
2631 * Fixed silc_server_command_identify_check_client to assemble
2632 correct WHOIS packet. It send corrupted WHOIS packet and
2633 caused problem with router to router connections. Affected
2634 file silcd/command.c.
2636 Fixed also silc_server_command_whois_check the same way
2637 as for the IDENTIFY command.
2639 * Added new SilcIDListStatus to the server in the SilcIDListData
2640 structure. The status now includes the current status of
2641 the entry (like registered, resolved etc.). Affected file
2642 silcd/idlist.[ch]. Defined a bunch of different status types
2643 as well. This replaced the old boolean registered field as well.
2645 Added resolve_cmd_ident field to the SilcClientEntry structure
2646 too so that if the entry is for example being resolved so
2647 another command may attach to the same pending command reply
2648 without requiring to resolve the same entry again. This concept
2649 should optimize the WHOIS and the IDENTIFY resolving under
2650 heavy load by taking away unnecessary resolving for entries
2651 that are being resolved already.
2653 Added support for adding multiple pending commands for one
2654 command idenfier. Affected file silcd/command[_reply].[ch].
2656 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2657 before deleting the data. Otherwise the hash table will have
2658 freed data in comparison functions. Affected file is
2659 silcd/command_reply.c.
2661 * Fixed silc_idlist_replace_client_id to add the new entry to
2662 the cache with NULL nickname. Otherwise there will be invalid
2663 memory as the nickname after the nickname is freed. Affected
2664 file silcd/packet_receive.c.
2666 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2667 saved into wrong slots because the previous number of entries
2668 was not taken into account. Affected file silcd/idlist.c.
2669 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2671 * If we are router and we receive JOIN notify to a channel that
2672 does not have any users then notified client is marked as the
2673 channel founder, as it is it. The affected file is
2674 silcd/packet_receive.c
2676 * Added to the extended hash table API's table_del_*ext functions
2677 the destructor as argument too, so that the caller can decide
2678 which destructor to use or whether to use destructor at all.
2679 Affected file lib/silcutil/silchashtable.[ch].
2681 * Fixed ID Cache purging. It actually deleted the entries from
2682 the hash table after the data was freed. The hash table ended
2683 up comparing freed memory. The affected file is
2684 lib/silccore/silcidcache.c.
2686 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2688 * Fixed Irssi SILC client's KILL command's HELP syntax.
2690 * The USERS command now resolves the detailed user information
2691 if the userinfo field is missing. Affected file is
2692 lib/silcclient/command_reply.c.
2694 * Do not print error in silc_file_read if the read file does
2695 not exist. Just silently return NULL. Affected file is
2696 lib/silcutil/silcutil.c.
2698 * Fixed the silc_log_output to not wine about NULL filename
2699 and to not create some bogus " " filename. Affected file is
2700 lib/silcutil/silclog.c.
2702 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2704 * Fixed various printing bugs on the user interface in the
2705 Irssi SILC Client. Minor changes that were forgotten from
2708 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2710 * Fixed the configure.in.pre and the compilation and distribution
2711 environment to support the new autoconf 2.52. That version is
2712 now required to compile the CVS trunk.
2714 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2716 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2717 to generally parse user@fqdn format strings. Affected file
2718 lib/silcutil/silcutil.c.
2720 * Added nickname_format and nickname_force_format fields to the
2721 SilcClientParams structure. The first one defines the format
2722 for the nicknames that the library will enforce if the receives
2723 multiple same nicknames. The second one is boolean value and
2724 can be used to force the library to always enforce the format
2725 to the nicknames regardles whether there are multiple nicknames
2726 or not. This configurable formatting was employed to flexibly
2727 support accessing multiple nicknames from the user interface.
2728 The userinterface can now set the nicknames to what ever format
2729 they prefer. Affected file lib/silcclient/silcapi.h.
2731 Added function silc_client_nickname_format to the file
2732 lib/silcclient/idlist.c. It performs the nickname formatting.
2734 Added new field `hostname´ to the SilcClientEntry context.
2735 It holds the hostname of the client. Affected file is
2736 lib/silcclient/idlist.h.
2738 * Irssi SILC Client sets the nicknames in nick@hostn format.
2739 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2740 irssi/src/silc/core/silc-core.c.
2742 The WHOIS printing now also shows both the real nickname and
2743 the formatted nickname so that user knows how to access the
2744 user if there are multiple same nicknames cached. Affected
2745 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2746 printing formatting too to take the hostname now as a separate
2747 argument. The Affected file is
2748 irssi/src/fe-common/silc/modules-formats.[ch].
2750 * Changed the silc_client_get_clients_local to accept the formatted
2751 nickname as argument. It accepts the real nickname too but the
2752 formatted nickname can be used to find the true entry from
2753 multiple entries. Affected file lib/silcclient/silcapi.h and
2754 lib/silcclient/idlist.c.
2756 * Added nickname_format_parse field to the SilcClientParams.
2757 It is a callback function provided by the application to parse
2758 the nickname out of the formatted nickname string. The library
2759 calls it to get the nickname from the formatted string. Since
2760 the application generally knows better the format of the nickname
2761 string it parses it instead of the library, even though library
2762 encodes the formatted string. If the callback function is not
2763 provided then the library will use the string as is. The
2764 affected file is lib/silcclient/silcapi.h.
2766 * All the nickname strings passed to the client library in
2767 commands are now expected to be formatted nickname strings.
2768 If the command does not support the formatted nickname string
2769 it will assume that the sent string is the actual nickname.
2770 Affected file lib/silcclient/command.c.
2772 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2774 * Added public key authentication support to OPER and SILCOPER
2775 commands in the client library. Affected file is
2776 lib/silcclient/command.c.
2778 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * Changed the get_auth_methdod client operation to be asynchronous.
2781 It can be async if the application resolves the authentication
2782 method from the server during the negotiation. Added new
2783 SilcGetAuthMeth completion callback that the application will
2784 call after resolving the authentication method.
2786 Added function silc_client_request_authentication_method that
2787 the application can use to resolve the authentication method
2788 from the server. Added also SilcConnectionAuthRequest callback
2789 that the library will call after the server has replied. The
2790 application can call this function if it does not know the
2791 current authentication method.
2793 Affected files are lib/silcclient/client.c and
2794 lib/silcclient/silcapi.h.
2796 * The Irssi SILC client now automatically resolves the authentication
2797 method incase any configuration information is not present (and
2798 currently there never is). The affected file is
2799 irssi/src/silc/core/client_ops.c.
2801 * Fixed public key authentication from the client library.
2802 Affected file lib/silcclient/protocol.c. Changed also the
2803 protocol specification about the public key authentication in
2804 the connection authentication protocol. The actual data to be
2805 signed is now computed with a hash function before signing.
2807 * Fixed the public key authentication from the server as well.
2808 Affected file silcd/protocol.c.
2810 * Removed the mlock()'s from the memory allocation routines.
2811 Affected file lib/silcutil/silcmemory.c. The ./configure does
2812 not check anymore for the mlock(). Affected file is
2815 * Fixed USERS command in server to allow the execution of the
2816 command for private and secret channels if the client sending
2817 the command is on the channel. Affected file silcd/command.c.
2819 * Fixed silc_client_get_clients_local to return the clients
2820 count correctly. It could return wrong value. Affected file
2821 lib/silcclient/idlist.c.
2823 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2825 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2826 types. The assembler optimizations seemed not to like 64-bit
2827 data types. The assmebler optimizations thus are now enabled
2828 also for BSD systems as opposed to only enable them for Linux.
2830 * Do not check for threads at all on BSD systems. Affected
2831 file configure.in.pre.
2833 * Removed -n and -h options from the Irssi SILC Client since
2834 they are not used in silc.
2836 * Fixed the prime generation to assure that the first digit
2837 of the generated random number is not zero since our conversion
2838 routines does not like number strings that starts with zero
2839 digit. If zero digit is seen the random number is regenerated.
2840 This caused some corrupted RSA keys when the zero first digit
2841 was met. Affected file lib/silcmath/silcprimegen.c.
2843 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2845 * Fixed WIN32 configuration in the ./configure script.
2846 Fixed to include xti.h on environments that has it.
2847 Patches by Carsten Ilchmann and andrew.
2849 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * Changed the silc_id_create_client_id to be collision
2852 resistant. It is now assured that there cannot be created
2853 two same client ID's. I suspect that some weird bugs in
2854 the server were actually caused by duplicate Client IDs.
2855 Affected file silcd/serverid.[ch]. A router receiving
2856 new ID now also assures and informs the sending server
2857 if the ID caused collision.
2859 * Changed the silc_id_create_channel_id to also assure that
2860 there are no collisions.
2862 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2864 * Statement about ignoring the Mutual Authentication flag when
2865 performing rekey with PFS was a bit misleading. It is ignored
2866 if it was set in the initial negotiation, it cannot be even
2867 set in the rekey. Fixed in the ke-auth draft. Started the
2868 new versions of the protocol drafts in the doc/.
2870 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2872 * Fixed a bug in silc_client_command_identify_save when saving
2873 new channel information. The channel name was no duplicated
2874 and caused crash on exit. Affected file is
2875 lib/silcclient/command_reply.c.
2877 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2879 * Fixed the getkey command handling in the server. Send just
2880 empty OK reply to the sender if the key could not be fetched
2881 (but everything else was ok, like the key just was not available).
2882 Changed the public key parameter to optional in the protocol
2883 specs so that empty OK reply can be sent. Affected file
2886 Added a message to Irssi SILC client to tell to user if the
2887 server did not return a public key.
2889 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2891 * Fixed a channel key regeneration bug. It registered new
2892 timeout tasks exponentially until all system resources were
2893 used. Affected file silcd/server.c.
2895 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2897 * Added the SILC Document generator to the scripts/silcdoc.
2898 It can be used to generate the Toolkit Reference Manual out
2899 of the source tree. Internally it will also use the RoboDoc
2900 generator now imported in util/robodoc.
2902 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2904 * Added couple of return's in rekey protocol if error orccurred
2905 during the protocol. The execution must be terminated.
2906 Affected file silcd/protocol.c. Also, terminate the protocol
2907 always with timeout.
2909 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * The client's Client ID was created initally from the wrong
2912 nickname (it could have been in format nick@host) in the
2913 silc_server_new_client. Affected file silcd/packet_receive.c
2915 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2917 * Added some SILC_LOG_ERROR's to various error conditions
2918 if client could not be added to ID cache. Affected files
2919 silcd/packet_receive.c and silcd/server.c.
2921 * When client's sock->user_data is freed, NULL also the
2922 client->router and client->connection pointers. Added check
2923 for these pointers being NULL to various places around the
2924 code. Affected file silcd/server.c.
2926 * Added client->data.registered == TRUE checks to various
2927 places around the code to assure that unregistered client's
2928 are not handled when it is not allowed. Affected file
2931 * Added `bool registered' fields to all
2932 silc_idlist_[server|client]_get_* routines to indicate whether
2933 the fetched client needs to be registered or not. Affected
2934 file silcd/idlist.[ch].
2936 * Add your own entry as registered to the ID cache in the
2937 server. Affected file server.c.
2939 * Fixed a bug in silc_server_new_server. The SilcServer was
2940 set as the new server's context instead of SilcServerEntry.
2941 This naturally caused some weird bugs.
2943 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2945 * Do not delete the channel rekey task when adding it
2946 for in silc_server_create_channel_key.
2948 * Changed the silc_server_create_channel_key to return
2949 TRUE or FALSE to indicate the success of the channel key
2952 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2954 * Fixed MSVC++ project files and added missing files to
2955 Makefiles under win32/.
2957 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2959 * Do not add TCP_NODELAY flag if the operating system
2960 does not have it defined. Affected files are
2961 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2963 * Fixed buffer overflow from Irssi SILC Client. Affected
2964 file irssi/src/fe-common/core/themes.c.
2966 * Fixed double free in client library in the file
2967 lib/silcclient/client.c when disconnecting from server.
2969 * Applied double free patch from cras to Irssi SILC client.
2970 Affected files irssi/src/core/[modules/expandos].c
2972 * Fixed the disconnection handling to Irssi SILC Client.
2973 The application must call silc_client_close_connection
2974 in ops->connect client operation in case of failure of
2975 the connection. Affected file is
2976 irssi/src/silc/core/client_ops.c.
2978 * Do not set sock->protocol to NULL in the function
2979 silc_client_close_connection after executing the protocol's
2980 final callback since the sock might not be valid anymore.
2981 Affected file lib/silcclient/client.c.
2983 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2985 * Do not enable SILC_THREADS if the linking with libpthread
2986 did not happen. Affected file configure.in.pre.
2988 * Added notion to protocol specification that server must
2989 verify the sent authentication payload with CMODE when
2990 setting the channel founder key. Implemented it to the
2991 server. Affected file silcd/command.c.
2993 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2995 * Added _EXTRA_DIST SILC distribution variable to the
2996 distributions file. It is used to conditionally add extra
2997 files or directories to the specific distribution. Affected
2998 files ./prepare, Makefile.am.pre and distributions.
3000 Removed the `_' from the start of the distribution names.
3003 * Added README.WIN32 for instructions to compile the Toolkit
3006 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3008 * Fixed a double free in disconnection in the server. Affected
3009 file is silcd/server.c.
3011 * Fixed the lib/silcske/groups.c to work now also with GMP
3012 MP library. The string conversion did not work when using
3013 specific base and the base is indicated in the string as well.
3015 * Created win32/ directory which now includes MSVC++ specific
3016 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3017 It will appear only in the toolkit distribution
3019 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3021 * Changed the key material distribution function in case when
3022 the hash output is too short. The data is now concatenated
3023 a bit differently than it used to. Made the change to the
3024 SKE protocol specification.
3026 * Added better GMP detection to configure.in.pre. A patch
3029 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3031 * Fixed a minor bug in SKE that might cause some problem on
3032 some platforms. Affected file lib/silcske/silcske.c.
3034 * Added the cookie checking for initiator in the SKE. It checks
3035 that the responder returns the sent cookie unmodified. The
3036 affected file is lib/silcske/silcske.c. Added new SKE
3037 error type INVALID_COOKIE that can be sent during the
3038 negotiation. Fixed some memory leaks as well.
3040 * Added the "invalid cookie" error message to Irssi SILC client's
3043 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3045 * Added `task_max' field to the SilcClientParams to indicate
3046 the maximum tasks the scheduler can handle. If set to zero,
3047 default values are used. Affected file lib/silcclient/silcapi.h.
3049 * Fixed memory leaks in silc_client_close_connection. Affected
3050 file lib/silcclient/client.c.
3052 * Added silc_client_del_client_entry to client library to free
3053 all memory of given client entry. Affected file is
3054 lib/silcclient/idlist.[ch].
3056 * Added new functions silc_client_del_channel and
3057 silc_client_del_server to delete channel and server entries.
3058 Affected file lib/silcclient/[silcapi.h/idlist.c].
3060 * Removed silc_client_del_client_by_id from silcapi.h.
3062 * Fixed the INFO command to return the server's own info
3063 correctly when querying by Server ID. Affected file is
3066 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3068 * Removed the non-blocking settings in WIN32 code in the
3069 silc_sock_[read/write] and added SleepEx instead. Affected
3070 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3071 of input data is now checked with FIONREAD and ioctlsocket.
3073 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3075 * Call silc_schedule_task_del_by_context in the
3076 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3077 Affected file lib/silccore/silcprotocol.c.
3079 * Call silc_protocol_cancel for active protocols in the
3080 silc_server_close_connection if the funtion
3081 silc_server_free_sock_user_data has not been called.
3082 Affected file silcd/server.c.
3084 * Generic tasks cannot be deleted using the del_by_fd
3085 task deleting function since generic tasks does not match
3086 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3088 * Added a notion to SILCOPER help file that the SILCOPER works
3089 only on router server, not on normal server.
3091 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3093 * Added for WIN32 support for the new scheduler as well.
3094 Affected file lib/silcutil/win32/silcwin32schedule.c.
3096 * Fixed the SHA1 implementation to work on various platforms.
3098 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3100 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3101 API. It is part of the scheduler now. Everything else is
3102 as previously but some functions has changed their names.
3103 Checkout the lib/silcutil/silcschedule.h for the interface.
3104 Updated all applications to use the new interface. Affected
3105 files are lib/silcutil/silcschedule.[ch].
3107 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3109 * Found a bug in the SKE implementation. The HASH value,
3110 specified by the protocol, was not computed correctly. The
3111 public key of the responder was not added to the computation
3112 even though it is mandatory. Affected file lib/silcske/silcske.c.
3113 This unfortunately causes incompatibilities with older
3114 clients and servers.
3116 * Added WIN32 specific network init and uninit functions:
3117 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3118 the Winsock2. Affected file lib/silcutil/silcnet.h and
3119 lib/silcutil/win32/silcwin32net.c.
3121 * Set the socket always to nonblocking mode on WIN32 after
3122 reading data or writing data. Affected file is
3123 lib/silcutil/win32/silcwin32sockconn.c.
3125 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3127 * Fixed various compilation problems under WIN32. Affected
3128 files lib/silcutil/win32/silcwin32thread.c and
3129 lib/silcutil/win32/silcwin32schedule.c.
3131 * Removed all _internal.h #includes from public header
3132 files. Internal headers must never be included from
3135 Removed also the lib/silcske/payload_internal.h file.
3137 * All include files that may be needed (public and some others
3138 included by the public headers) by application developers are
3139 now copied to the ./includes directory. It does not copy any
3140 internal headers. Affected file Makefile.defines.pre and all
3141 Makefile.am's under lib/ and subdirs.
3143 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3145 * Do not change the ~/.silc directory's permissions automatically.
3146 Affected file irssi/src/silc/core/clientutil.c.
3148 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3150 * Do not cancel the protocol in silc_server_close_connection
3151 it might cause recursion. Now cancelled in the function
3152 silc_server_free_sock_user_data. Affected file silcd/server.c.
3154 * Fixed the silc_server_remove_clients_by_server to regenerate
3155 the channel keys correctly finally. Added also new function
3156 silc_server_remove_clients_channels to actually do it.
3157 Affected file silcd/server.c.
3159 * Fixed the silc_server_new_channel to not crash by giving
3160 wrong router to the new channel. Affected file is
3161 silcd/packet_receive.c.
3163 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3165 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3166 which is given as argument to the silc_client_alloc now.
3167 It can be used to configure the client and set various parameters
3168 that affect the function of the client.
3170 * The USERS command in server did not check whether the channel
3171 is private or secret. Affected file silcd/command.c.
3173 * Added new argument to the USERS command in protocol specification.
3174 The USERS command now can take the channel name as argument
3175 as well. Added support for this in client and server and
3176 updated the protocol specs.
3178 * Completed the GETKEY command in client. It can be now used
3179 to fetch also servers public key not only some clients.
3180 Affected files lib/silcclient/command[_reply].c.
3182 * Added silc_client_get_server to return server entry by the
3183 server name. Affected files lib/silcclient/silcapi.h and
3186 * Redefined the IDENTIFY command in protocol specification to be
3187 more generic. It now can be used to query information about
3188 any entity in the SILC Network, including clients, servers and
3189 channels. The query may be based either the entity's name
3190 or the ID. Added support for this in both client and server.
3192 Affected files silcd/command.c and lib/silcclient/command.c
3193 and command_reply.c.
3195 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3196 the _from_client and _from_server functions. Affected file
3199 * Added silc_client_get_channel_by_id_resolve to the file
3200 lib/silcclient/silcapi.h to resolve channel information by
3201 its ID. Added also silc_client_get_channel_by_id that
3202 does not resolve it from the server.
3204 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3206 * Added SilcServerEntry context into the client library
3207 to represent one server. The INFO command now allocates
3208 these to save the resolved server info. For now on the
3209 client library will also keep information about servers,
3210 connected and resolved with INFO.
3212 The INFO command now allocates the SilcServerEntry context
3213 and saves the server info there. The COMMAND_REPLY in
3214 the INFO now returns the parameters to application in
3215 same order as defined in the protocol specification.
3217 The entries are cached in the client->server_cache.
3219 * The INFO command is now issued after received the Client ID
3220 from the server. Affected file lib/silcclient/client.c.
3222 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3223 to the application as the mode changer might be server.
3224 It is guaranteed that NULL is not returned anymore to the
3225 application. Affected file lib/silcclient/client_notify.c.
3227 The ID Type is now also passed to the application so that
3228 it can check whether the returned entry is SilcClientEntry
3231 Added new function silc_client_get_server_by_id to return
3232 the server entry by ID. Affected files are the
3233 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3235 * Do not create the channel in the Irssi SILC Client when issuing
3236 the JOIN command but when received the sucessful JOIN command
3237 reply. Otherwise the channel might get created even though we
3238 could not join it. The Affected file is
3239 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3241 * Fixed a channel joining bug in router. The router must also
3242 check the channel modes, invite and ban lists etc. when serving
3243 the JOIN command sent by normal server. Affected file is
3244 silcd/command.c. The router now resolves the client's
3245 information from the server who sent the JOIN command if it
3246 does not know it, and processes the JOIN command only after
3249 * Changed the SilcCommandCb to take new argument; void *context2.
3250 Affected file lib/silccore/silccommand.h
3252 The second argument in the command callbacks in the server now
3253 includes the SilcServerCommandReplyContext if the command was
3254 called as pending command callback from the command reply.
3255 Otherwise it is NULL. When called as pending the status of the
3256 command reply will be checked and if it was erronous the
3257 error will be sent to the original sender of the command.
3258 This way the client always receives the error messages even
3259 though the server was actually the one who received the error
3260 when it resent the command to router, for example. Affected
3261 files silcd/command[_reply].[ch].
3263 * Fixed sending WHOWAS command's error message to client if
3264 the requested client could not be found. It was missing.
3267 * Changed the CMODE and CUMODE commands reply arguments in the
3268 protocol specification. The Channel ID is now sent in both
3269 of the commands to identify the channel. Implemented this
3270 new feature to the client and server. Affected files
3271 lib/silcclient/command_reply.c and silcd/command.c.
3273 * Made better checks for invite and ban lists in the JOIN
3274 command in server. Affected file silcd/command.c.
3276 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3278 * The server now performs the incoming host IP/DNS lookup
3279 using the silc_socket_host_lookup and thus does not block
3280 the server anymore. Affected file silcd/server.c.
3282 * Completed the multi-thread support for SILC Scheduler in
3283 the lib/silcutil/silcschedule.c.
3285 * Fixed the configure.in.pre to detect the pthread correctly
3288 * Fixed a deadlock in silc_task_queue_wakeup in the file
3289 lib/silcutil/silctask.c.
3291 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * Added new function silc_schedule_wakeup that is used in
3294 multi-threaded environment to wakeup the main thread's
3295 schduler. It needs to be used when a thread adds a new task
3296 or removes a task from task queues. After waking up, the
3297 scheduler will detect the task queue changes. If threads
3298 support is not compiled in this function has no effect.
3299 Implemented the wakeup mechanism to both Unix and WIN32
3300 systems. Affected files are lib/silcutil/silcschedule.[ch],
3301 lib/silcutil/unix/silcunixschedule.c and the
3302 lib/silcutil/win32/silcwin32schedule.c.
3304 * Added new function silc_task_queue_wakeup to wakeup the
3305 scheduler by the specified task queue. Affected file
3306 lib/silcutil/silctask.[ch].
3308 * The silc_socket_host_lookup_start now wakes up the scheduler
3309 after adding the timeout task. Affected file is
3310 lib/silcutil/silcsockconn.c.
3312 * The silc_socket_host_lookup is synchronous now if the threads
3313 support is not compiled in. However, the callback is still
3314 called asyncronously through the scheduler, anyway. Affected
3315 file lib/silcutil/silcsockconn.c.
3317 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3319 * Added new function silc_socket_host_lookup to perform
3320 asynchronous IP and FQDN lookups for the socket connection.
3321 Affected files lib/silcutil/silcsockconn.[ch].
3323 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3325 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3326 that may or may not compile the mutex support in.
3328 Changed the silc_mutex_alloc interface. It allocates the
3329 mutex now to the sent pointer and returns TRUE or FALSE.
3331 Affected file lib/silcutil/silcmutex.h.
3333 * Wrote the SILC Task Queue interface to support multi-threads.
3334 Affected file lib/silcutil/silctask.[ch].
3336 * Wrote the SILC Scheduler to support multi-threads. Affected
3337 file lib/silcutil/silcschedule.c.
3339 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3341 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3342 in lib/silcutil/win32/.
3344 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3346 * Defined SILC Mutex API and SILC Thread API and implemented
3347 them for Unix. Affected files are
3348 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3349 lib/silcutil/unix/silcunixmutex.c and
3350 lib/silcutil/unix/silcunixthread.c.
3352 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3354 * Fixed the silc_server_remove_clients_by_server's channel
3355 key re-generation. The hash table handling was incorrect
3356 and would not work with many channels. Affected file is
3359 * Fixed some memory leaks around the server code.
3361 * Rewrote the silc_server_get_users_on_channel to support IPv6
3362 based Client ID's. Affected file silcd/server.c.
3364 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3365 specification. However, a separate document must be written
3366 to define the detailed signing procedure and the payload
3367 associated with the flag. Defined the flag to the
3368 lib/silccore/silcchannel.h as well.
3370 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3372 * Changed the dynamic tables to static size tables in the
3373 lib/silccrypt/silchmac.c.
3375 * Removed GCC dependencies from the code. A patch by cras.
3377 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3379 * Do not show the error "Error receiving packet bla bla"
3380 in server if it really was not an error (-2 means that reading
3381 is pending). Affected file silcd/server.c.
3383 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3385 * Fixed a possible crash in silc_server_remove_clients_by_server
3386 in silcd/server.c. Fixed there also some memory leaks.
3388 * Fixed the silc_idlist_replace_client_id. It could replace
3389 wrong key in the hash table. Affected file silcd/idlist.c.
3391 * Do not check whether there are global users on the channel
3392 if the channel->global_users is FALSE. Affected functions
3393 silc_server_remove_from_one_channel and
3394 silc_server_remove_from_channels in silcd/server.c. Also,
3395 do not check if the removed client is local as we can be
3396 sure that global client was not removed from the channel
3397 and checking for global users is not needed.
3399 * The silc_server_remove_clients_by_server now re-generates
3400 the channel keys correctly for those channels that had
3401 clients removed from them. Affected file silcd/server.c.
3403 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3405 * Found the reason of random crashes in the server. We weren't
3406 ignoring the SIGPIPE signal (which can be sent in write())
3407 and it crashed the server. Affected file silcd/silcd.c.
3409 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3411 * Assure that sock->user_data is not NULL in the function
3412 silc_server_packet_send in silcd/packet_send.c.
3414 * Disconnect the remote connection if it could not be added
3415 to any ID lists in the server. The affected file is
3418 * Check in silc_server_packet_send[_real/dest] that the
3419 socket is not disconnecting and ignore the data if it is.
3420 Affected file silcd/packet_send.c.
3422 * Define inline to __inline on native WIN32 compilation.
3423 Affected file includes/silcwin32.h.
3425 * Added some explicit type casts for inline code since MSVC
3426 require them. Affected files lib/silcutil/silcbuffer.h,
3427 lib/trq/silcdlist.h and lib/trq/silclist.h.
3429 * Print warning in log files from now on if the packet
3430 decryption fails. Affected file silcd/server.c.
3432 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3434 * Changed the `say' client operation's interface to accept
3435 new `type' argument to indicate the type of the message sent
3436 by the library. The application may filter the library's
3437 messages according the type. The affected file is the
3438 lib/silcclient/silcapi.h.
3440 * Added two new functions to lib/silcclient/silcapi.h:
3441 silc_client_del_client and silc_client_del_client_by_id.
3442 Affected file lib/silcclient/idlist.c.
3444 * Moved the clientincludes.h from includes/ to silc/ and
3445 serverincludes.h from includes/ to silcd/.
3447 * The modes for the CMODE and CUMODE are now passed as
3448 uint32 for application with COMMAND_REPLY. The affected
3449 file is lib/silcclient/command_reply.c.
3451 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3453 * /WHOIS without arguments shows client's own information.
3454 Affected file lib/silcclient/command.c.
3456 * Changed PING to not accept any arguments. The specs
3457 says that client can ping only the connected server so
3458 requiring an argument is not needed. Affected file is
3459 lib/silcclient/command.c.
3461 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3463 * Fixed a fatal bug in private message sending and reception
3464 encryption and decryption when using private message keys.
3465 The implementation was incorrect and did not follow the
3466 specification. It causd that some of the message were
3467 lost since it did not use the sending and receiving keys
3468 as the protocol suggests. This has been fixed and will cause
3469 incompatibilities with older clients when sending private
3470 message encrypted with private message keys. Affected files
3471 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3472 and various other in Irssi SILC Client.
3474 Added `responder' boolean argument to the functions
3475 silc_client_add_private_message_key[_ske] to indicate when
3476 the key is added as responder or initiator of the key
3479 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3481 * Removed the silc_ske_check_version function and created
3482 a SilcSKECheckVersion callback. Added also a function
3483 silc_ske_set_callbacks that is now used to set all SKE
3484 callbacks. The callback functions are not given to
3485 the SKE functions anymore, but this function is used to
3488 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3490 * Added `silc_version' argument to the silc_client_alloc
3491 to define the version of the application for the library.
3492 The library will use the version string to compare it
3493 against the remote host's (usually a server) version
3494 string. Affected file lib/silcclient/silcapi.h
3496 * Added the KE protocol context to Key Agreement context
3497 in client library so that we can abort the SKE if it
3498 is in process when we get timeout. Affected file is
3499 lib/silcclient/client_keyagr.c.
3501 * Do not resolve the client ID forever if it returns in the
3502 first time that such client does not exist. This was done
3503 for example with private message. Affected file is
3504 lib/silcclient/client_prvmsg.c.
3506 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3508 * Do not add regex.h for WIN32. The affected file
3509 includes/silcincludes.h.
3511 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3512 not work yet 100%. It generates the DLL's automatically
3513 when compiling with --with-win32 under cygwin.
3515 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3517 * lib/contrib/regex.c is not compiled on WIN32.
3519 * Added silc_net_get_socket_opt function to the
3520 lib/silcutil/silcnet.h.
3522 * Added includes/silcwin32.h for WIN32 specific includes
3525 * Do not use ptime structure or any of the posix process
3526 functions on WIN32 in lib/silccrypt/silrng.c.
3528 * Added silc_gettimeofday to provide generic function
3529 for struct timeval on all platforms. Added the function
3530 to lib/silcutil/silcutil.h.
3532 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3534 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3535 library as they clearly belong there. As a plus side we
3536 can make the actual socket connection routines platform
3539 Added also new generic function silc_socket_read and
3540 silc_socket_write (that used to be silc_packet_[read/write].
3541 The implementation of these are platform specific.
3543 * Added WIN32 specific routines of silc_socket_[read/write]
3544 to lib/silcutil/win32/silcwin32sockconn.c.
3546 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3548 * Added preliminary support for native WIN32 compilation under
3549 cygwin (using the -mno-cygwin option for GCC) to the
3550 ./configure.in.pre. The --with-win32 now prepares the
3551 compilation for native WIN32.
3553 * Rewrote the SILC Scheduler interface in the file
3554 lib/silcutil/silcschedule.h. The scheduler is now context
3555 based and does not have anymore any global static scheduler.
3556 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3557 and created lib/silcutil/win32 directory for WIN32 based
3560 * Added Unix specific network routines to the
3561 lib/silcutil/unix/silcunixnet.c and the old
3562 lib/silcutil/silcnet.c includes now only generic routines.
3564 Added WIN32 specific network routines to the
3565 lib/silcutil/win32/silcwin32net.c.
3567 * Added Unix specific utility functions from the
3568 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3570 * Added WIN32 SILC Scheduler to the file
3571 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3574 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3576 * Do not handle JOIN notify in the server if the target client
3577 is not registered (idata->registered == FALSE). The affected
3578 file is silcd/packet_receive.c.
3580 * Update the nickrec->founder in event_cumode in the Irssi SILC
3581 client. Affected file irssi/src/silc/core/silc-channels.c.
3583 * Fixed the CUMODE_CHANGE notify handling in the server when
3584 server and router are announcing their clients on channels.
3585 Now the mode changes are saved and notified correctly. The
3586 affected file is /silcd/packet_receive.c.
3588 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3589 They really did not replace the cache entry in the ID Cache.
3590 Now they do that. Affected file silcd/idlist.c.
3592 * Fixed the KICK notify handling in the Irssi SILC client to
3593 update the channel records so that the kicked client does not
3594 appear to be on the channel. The affected file is
3595 irssi/src/silc/core/silc-channels.c.
3597 * Always update the conn->current_channel when executing command
3598 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3600 * Fixed the KILL notify handling in Irssi SILC client to remove
3601 the killed client on all channels.
3603 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Fixed the silc_parse_command_line to remove extra spaces
3606 from the start and end of the arguments. Affected file is
3607 lib/silcutil/silcutil.c.
3609 * Cancel and free any active protocol in the function
3610 silc_server_close_connection. Affected file silcd/server.c.
3612 * Cancel and free any active protocol in the function
3613 silc_client_close_connction. Affected file is
3614 lib/silcclient/client.c.
3616 * Do not execute the KILL command for clients that are in
3617 history (ie. they are not in the network). Affected file is
3620 * Fixed KILL notify handling, client does not crash anymore.
3621 Affected file irssi/src/silc/core/silc-channels.c.
3623 * Reduced the default packet buffer size from 2048 to 1024 in
3624 lib/silccore/silcpacket.c.
3626 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3627 counter to the SKE context that is incresed when the SKE library
3628 performs async operation outside the library. If the outside
3629 process frees the SKE context and FREED status will be set
3630 and the library will detect after the sync operation that the
3631 libary is freed. The affected files are
3632 lib/silcske/silcske[_status].[ch].
3634 * Resolve the client entry information in the function
3635 silc_client_channel_message to assure that NULL pointer is not
3636 passed as client entry to the application. */
3638 * Fixed the task timeout calculation to assure that there is
3639 never negative timeouts. The affected file is
3640 lib/silcutil/silcschedule.c.
3642 * Fixed the channel user mode notification sending in server.
3643 It was sent point-to-point to the router (or to server by router)
3644 but it needs to be destined to a channel. The routines now
3645 supports sending the channel user mode notifys to the channels
3646 when announcing clients and channels. Affected files are
3647 silcd/server.c and silcd/packet_receive.c.
3649 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3650 It did not actually replace the old channel entry in the cache.
3651 Affected file lib/silcclient/client_notify.c.
3653 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3655 * Fixed a possible crash in silc_packet_send_prepare. It now
3656 assures always that there is enough space in the buffer and
3657 at the tail area of the buffer (for MAC).
3659 Fixed the inbound buffer reallocation in silc_packet_read.
3660 It was old code and did not handle the reallocation correctly.
3663 The affected file is lib/silccore/silcpacket.c.
3665 * Fixed buffer overflow in silc_parse_nickname in the file
3666 lib/silcutil/silcutil.c.
3668 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3670 * make install generates new server keys only if there is not
3673 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3675 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3676 Added check that if the NOREPLY is set then we will not send
3677 the away message. This avoids infinite loop of away messages
3678 if both clients are away. The affected file is
3679 lib/silcclient/client_prvmsg.c.
3681 * Fixed client crash if /NICK was given without arguments.
3682 Affected file lib/silcclient/command.c.
3684 * Server does not send the invite list in INVITE command back
3685 to the client if the list was not altered. Added this notion
3686 to the protocol spec as well. Affected file silcd/command.c.
3688 Fixed possible crash in INVITE command by checking the
3689 value of silc_server_get_client_route command.
3691 * Fixed the INVITE notify type handling. The arguments are now
3692 taken in correct order and client does not crash. The affected
3693 file is irssi/src/silc/core/silc-channels.c.
3695 Removed the "Inviting xxx to channel" message from the
3696 client library away and let the application handle it.
3697 Affected file lib/silcclient/command.c. Added that message
3698 to Irssi SILC client's message formats.
3700 * Fixed CMODE command crash in client. It now checks the
3701 amount of arguments correctly and does not crash. The affected
3702 file is lib/silcclient/command.c.
3704 * Do not create new channel automatically in silc_channels_join
3705 but check whether the channel by that name already exists.
3706 Affected file irssi/silc/core/silc-channels.c.
3708 * Do not send the SERVER_SIGNOFF to router if the disconnected
3709 entity was the router. Affected file silcd/server.c.
3711 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3712 SILC client as it was missing from there.
3714 Added the handling of the KICK notify to the Irssi SILC client
3715 as it was missing. Added "you have been kicked" message to
3716 Irssi SILC client's message modules formats.
3718 Added the handing of the KILL notify to the Irssi SILC client
3719 as it was missing. Added the kill message module formats
3722 The affected file is irssi/src/silc/core/silc-channels.c.
3724 * The router did not save the channel mode the server announced.
3725 Affected file silcd/packet_receive.c.
3727 * Fixed a possible crash in INFO command in server. If the
3728 server did not provide the server info it crashed. Affected
3729 file silcd/command.c.
3731 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3733 * Fixed the GETKEY command in the server to check also the
3734 global list. Otherwise the GETKEY would not work correctly
3735 in normal SILC server. Affected file silcd/command.c.
3737 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3739 * Fixed GETKEY crash, it crashed if the command did not succseed.
3741 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3743 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3744 is now real and not just an macro interface to GMP.
3746 Removed the entire GMP from the source tree and imported new
3747 NSS MPI library instead. Reason for removing GMP is that it is
3748 extremely large and compiles extremely slow. The NSS MPI
3749 is only a few files and compiles in less than 10 seconds.
3750 The speed is also about the same as GMP. The MPI is imported
3751 to lib/silcmath/mpi.
3753 If the system has GMP installed we will still use the GMP.
3754 If it is not then the NSS MPI will be compiled.
3756 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * Merged a long nickname (127 characters long) crash bugfix from
3759 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3761 * Merged a freed memory reference bugfix from Irssi CVS tree.
3762 Affected file irssi/src/core/commands.c.
3764 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3766 * Added the server's public key sving and verification to the
3767 server when performing the SKE. This was missing and the
3768 remote server's (or router's) public key was accepted without
3769 checking whether we have it previously or trust it at all.
3770 Affected file silcd/protocol.c.
3772 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3774 * Check in the silc_server_timeout_remote if protocol is active
3775 and make sure that the protocol's final callback is called so
3776 that all memory if freed. Affected file silcd/server.c.
3778 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * silc_server_whois_send_reply crashed the server if the nickname
3781 was 127 characters long. Affected file silcd/command.c.
3783 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Added sanity check to the silc_server_new_client. If the hostname
3786 is provided inside username then check that the provided hostname
3787 really is the same as the resolved one. If the hostname was not
3788 resolved then check it from the public key. Affected file is
3789 silcd/packet_receive.c.
3791 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3792 if the server disconnected us and the connection is not valid
3793 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3795 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3796 the library to the lib/silcutil/silcutil.[ch].
3798 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3800 * Close log file after open. Affected file
3801 lib/silcutil/silclog.c.
3803 * Check whether sock == NULL in silc_client_send_packet and return
3804 if it is. Affected file lib/silcclient/silcclient.c.
3806 * Check rec->entry == NULL in the Irssi SILC Client before
3807 sending the channel message. Affecte file is
3808 irssi/src/silc/core/silc-servers.c.
3810 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3812 * Merged a splitted window bugfix from Irssi CVS tree. The
3813 affected file is irssi/src/fe-text/textbuffer-view.c.
3815 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3816 It did not print nickname.
3818 * Improved the distributions system a bit.
3820 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3822 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3823 irssi/src/fe-text/gui-window.c.
3825 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3826 to in-active server. The affected file is
3827 irssi/src/silc/core/client_ops.c.
3829 * Resolve the client in USERS command reply if the entry does
3830 not have username resolved. The affected file is
3831 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3832 command to WHOIS command to really resolve stuff. The USERS
3833 is not used any more in any critical section so WHOIS can
3834 be used even though it might be slower than IDENTIFY.
3836 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3839 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3841 * Changed the protocol API a bit more consistent in the
3842 lib/silccore/silcprotocol.[ch].
3844 * Changed the following headers to ROBODoc format:
3846 lib/silccore/silcpayload.h
3847 lib/silccore/silcprotocol.h
3848 lib/silccore/silcsockconn.h
3850 All core library headers are now formatted.
3852 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3854 * Fixed a bug in Irssi SILC client; do not show that you are
3855 server/router operator if you really are not. Affected file is
3856 irssi/src/silc/core/client_ops.c.
3858 * Renamed silc_command_free_payload to silc_command_payload_free.
3859 Affected file lib/silccore/silccommand.h
3861 * Added silcmath.h to include the prototoypes of various routines
3862 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3865 * Changed the following headers to ROBODoc format:
3867 lib/silccore/silcchannel.h
3868 lib/silccore/silccommand.h
3869 lib/silccore/silcid.h
3870 lib/silccore/silcidcache.h
3871 lib/silccore/silcmode.h
3872 lib/silccore/silcnotify.h
3873 lib/silccore/silcpacket.h
3874 lib/silcmath/silcmath.h
3876 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3878 * Added checking to the server code not to start the server if
3879 ciphers and stuff are not configured properly. Affected files
3880 silcd/serverconfig.[h] and silcd/server.c.
3882 * Changed the layout of the header files of the public interfaces
3883 in the SILC libraries. The new layout supports ROBODoc
3884 documentation tool (and some others) so that it is easy to create
3885 a library reference manual. All the other headers and source
3886 code must still follow the CodingStyle document. Also source
3887 code must not include these ROBODoc stuffs, only the headers.
3888 Furthermore, all public interface headers must now be named
3889 by using `silc' prefix, example: silcapi.h, silccipher.h.
3890 Some files were renamed due to this. All the other headers
3891 must not be used as public interfaces. I will update the
3892 CodingStyle document later. Changed following headers, so far:
3894 lib/silcclient/silcapi.h
3895 lib/silccore/silcauth.h
3896 lib/silccore/silcprivate.h
3897 lib/silccrypt/silcdh.h
3899 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3903 * Removed silc_client_packet_send_flush from the client library
3904 as it is not needed. Affected file lib/silcclient/client.[ch].
3906 * Added printing of message of unresolved authentication method
3907 to the Irssi SILC client. Added it to the module formats.
3908 Removed the same message from the client library.
3910 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3912 * Added new distribution feature, DISTLABEL. Every distribution
3913 can define own preprocessor label that can be used in the
3914 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3915 file distributions, acconfig.h.pre and prepare.
3917 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3919 * Added Makefile.defines_int to include the actual definitions
3920 for Makefile.defines.in. Tested the new distribution system,
3921 created distributions and tested installation.
3923 * Added AWAY message printing to the Irssi SILC client. Added
3924 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3926 * Added SCONNECT command to call the SILC's CONNECT command.
3927 Cannot use CONNECT directly since Irssi uses that internally.
3928 Affected file irssi/src/silc/core/silc-servers.c.
3930 Added ACTION local command. It is same as ME command but takes
3931 the channel as mandatory argument.
3933 Rewrote some of the Irssi's help files to suite for SILC
3936 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Added Makefile.defines[.in] that should for now on be included
3939 in all Makefile.am file in the source tree. That file includes
3940 all common compilation definitions for SILC source tree.
3942 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3944 * Minor changes to the ./prepare script to change the package
3945 name according the distribution name to the configure.in.
3947 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3949 * Created new distribution system. Added file `distributions'
3950 that defines all the distributions that can be created out of
3951 the SILC source tree. The ./prepare script now reads that
3952 file to determine how to prepare the distributions. The
3953 first argument to the ./prepare is the name of the distribution
3954 and second is the version of the distribution. If given
3955 without arguments it creates the default (toolkit) distribution
3956 with the default version (defined in ./prepare).
3958 All Makefile.am files that are subject to the distributions
3959 are now named as Makefile.am.pre. These are ./Makefile.am
3960 and lib/Makefile.am. Others may be changed later.
3962 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3964 * Added invite list, ban list, some key management and connection
3965 error message printing to module formats in the Irssi SILC client.
3967 * Added new silc_client_set_away_message to set the away message
3968 that is back to the person who sent private message. The
3969 affected file lib/silcclient/silcapi.h and the
3970 lib/silcclient/client_prvmsg.c.
3972 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3974 * Fixed the private message sending in the Irssi SILC client,
3975 added local command KEY to the Irssi SILC client.
3977 Added key management and key agreement message formats to the
3978 irssi/src/fe-common/silc/module-formats.[ch].
3980 Added USERS (alias WHO) printing, server/router operator
3981 indication and LIST command printing to the module formats.
3983 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Fixed channel joining notify handling, cumode notify handling
3986 from Irssi SILC client.
3988 * Added SILC specific module-formats to the Irssi SILC client so
3989 that SILC specific message hilighting, colors etc is possible.
3990 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3992 Added channel mode, channel user mode, actions, notices,
3993 whois and whowas printing to the the module-formats.c.
3995 * Fixed a bug in channel deletion in the server. The channel
3996 is not left to the cache even if the channel founder auth mode
3997 is set when there are no users anymore on the channel. Affected
3998 file silcd/server.c.
4000 * The silc_net_localhost now resolves the entire hostname including
4001 the domain name. Affected file lib/silcutil/silcnet.c.
4003 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Changed the ask_passphrase client operation to be ascynchronous.
4006 It has now a completion callback and a context that the
4007 application must call after it has got the passphrase from
4008 the user. Affected files lib/silcclient/silcapi.h,
4009 lib/silcclient/protocol.c, lib/silcclient/command.c and
4012 Added SilcAskPassphrase callback that the application calls
4013 to deliver the passphrase to the library.
4015 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4016 The public key verification and especially a certificate
4017 verification is asynchronous procedure.
4019 Added new SILC_SKE_STATUS_PENDING status to indicate the
4020 request is pending and a callback will be called to finalize
4023 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4024 indicate that remote end did not send its public key (or
4025 certificate), even though we require it. Added check for this
4026 condition in the SKE. This was a security bug, now fixed.
4028 Defined new SilcSKEVerifyCbCompletion callback that is called
4029 when the verification process is completed.
4031 The affected files lib/silcske/silcske_status.h and
4032 lib/silcske/silcske.[ch].
4034 * Changed the verify_public_key client operation to be async
4035 as well. Defined SilcVerifyPublicKey callback that is used to
4036 indicate the success of the public key verification process.
4038 Changed the server and client to use the new async client
4041 * Changed the Irssi SILC client's internal scheduler to be called
4042 twice as many times as it used to be. As a result the client
4043 should be a bit faster now. Affected file is
4044 irssi/src/silc/core/silc-core.c.
4046 * Added support to Irssi SILC client of asynchronous public key
4047 verification and passphrase inquiry. Affected file is
4048 irssi/src/silc/core/silc-core.c.
4050 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4052 * Do not say "You have left channel %s" in client library.
4053 Moved it to the application. Affected files are
4054 lib/silcclient/command.c and silc/client_ops.c.
4056 * Fixed silc_client_get_clients. Command context was not
4057 duplicated and was freed memory in the callback. Affected
4058 file lib/silcclient/idlist.c.
4060 * Do not say "you are now talking..." on JOIN command in the
4061 client library. The appliation must handle it.
4063 * Do not say ".. changed topic to" in command reply in the
4064 client libary. The application must handle it.
4066 * Fixed TOPIC command sending in the client library.
4068 * Fixed a memory leak in silc_client_command_free in the file
4069 lib/silcclient/command.c.
4071 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4073 * Imported a modified version of Irssi client to the source tree.
4074 The Irssi will be used to create a new client called
4075 Irssi SILC. Imported to irssi/.
4077 Added silc_core_init_finish function to the Irssi. Affected
4078 file irssi/configure.in.
4080 A lot changes in the Makefile.ams around the irssi tree.
4082 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4084 * Do not rehash if the new size is same as the old size of the
4085 hash table, in the silc_hash_table_rehash*. The affected file
4086 lib/silcutil/silchashtable.c.
4088 * Replaced hash_table_del_by_context calls from the server
4089 (when channel->user_list and client->channels) to the
4090 hash_table_del as it is sufficient and faster.
4092 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4094 * Added silc_hash_table_list, silc_hash_table_get and the
4095 SilcHashTableList structure to provide an alternative way to
4096 traverse the hash table. The affected files are
4097 lib/silcutil/silchashtable.[ch].
4099 * Changed the server's idlist routines to use the hash table
4100 routines to optimize the code.
4102 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Replaced the client entry's `channel' list and channel entry's
4105 `user_list' list to hash tables for optimized lookup. Changed
4106 the code to use the hash table interface around the code.
4107 Affected file lib/silcd/idlist.[ch].
4109 * Added `auto_rehash' boolean argument to the function
4110 silc_hash_table_alloc to indicate whether the hash table should
4111 auto-rehash when it thinks is appropriate time. It will
4112 increase the hash table size if the there is twice as much
4113 entries in the table than the size of the table, and will
4114 decrease the size if there are twice as less entries than
4115 the size of the table.
4117 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4121 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4123 * silc_idcache_purge_by_context deletes the entry now by context
4124 as it is supposed to do. Affected file lib/silccore/idcache.c.
4126 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4127 client is not anymore valid (WHOWAS givens the info) and not
4128 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4130 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * Removed the `data' and `data_len' arguments from the ID Cache
4133 interfaces and added `name' argument. ID Cache does not handle
4134 anymore the binary data only a names associated with given ID.
4136 * When hashing a Client ID with silc_hash_id the entire ID is
4137 not hashed anymore, instead only the hash of the Client ID is
4138 hashed. This way we can access the Client ID from the cache
4139 with Client ID but with the hash of the ID (which is a hash of
4140 the nickname) as well without any difference in performance.
4142 Added also silc_idcache_find_by_id_one_ext to do one on one
4143 searching when we have the actual ID. Added also function
4144 silc_hash_client_id_compare. The affected files are
4145 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4147 * When hashing the name associated with a ID it is always done
4148 in lowercase. This way we can access the cache without worrying
4149 about case-sensitivity, even though, for example nicknames are
4152 * Fixed a bug in server with channel message sending. It put
4153 wrong ID type as destination ID. The affected file
4154 silcd/packet_send.c.
4156 * silc_idcache_del_by_context now deletes from all hash tables
4157 by context. Affected file lib/silccore/idcache.c.
4159 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4161 * Changed the client library to use the new ID Cache interface.
4162 Changes around the source tree.
4164 * Added silc_hash_table_rehash_ext to rehash with specific
4165 hash function. Affected file lib/silcutil/silchashtable.[ch].
4167 * Added silc_hash_string_compare to compare two strings in the
4168 hash table. Affected file lib/silcutil/silcutil.[ch].
4170 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4172 * Added new function silc_idcache_del_by_context into the
4173 lib/silccore/idcache.[ch].
4175 * Changed the server's ID list routines to use the new ID Cache
4176 interface. Changes around the source tree.
4178 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * Added silc_hash_table_del[_by_context]_ext functions in to the
4181 lib/silcutil/silchashtable.[ch].
4183 Removed silc_hash_table_find_all* routines and added new
4184 silc_hash_table_find_foreach to replace them.
4186 Added silc_hash_table_replace_ext function as extended
4187 replacing function. Separated the simple hash table interface
4188 from the extended hash table interface in the file
4189 lib/silcutil/silchashtable.h.
4191 * Fixed minor bugs and changed it to use some of the new
4192 hash table functions in lib/silccore/idcache.c
4194 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Added new function silc_hash_table_find_all to return all keys
4197 in the hash table by the specified key. As the hash table is
4198 collision resistant it also makes it possible to have several
4199 duplicate keys in the hash table. This function may be used to
4200 find all of the keys from the hash.
4202 Added user_context arguments to the SilcHashFunction,
4203 SilcHashCompare and SilcHashDestructor to deliver user specified
4206 Added new fuctions silc_hash_table_find[_all]_ext to do
4207 extended lookup with specified hash and compare functions and
4208 specified user contexts.
4210 Added new function silc_hash_table_add_ext to add the key
4211 with specified hash function and user context.
4213 Added new function silc_hash_table_foreach to traverse all
4214 entrys in the hash table. Added SilcHashForeach callback
4217 Added new function silc_hash_table_del_by_context to delete
4218 the entry only if the context associated with the key matches.
4220 Affected files are lib/silcutil/silchashtable.[ch].
4222 * Removed silc_hash_[server/client/channel]_id and added just
4223 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4224 silc_hash_id_compare to compare two ID's using as the hash table
4225 comparison function. Added also silc_hash_data to hash
4226 binary data and silc_hash_data_compare to compare it.
4228 * Removed silc_idlist_find_client_by_hash as it is not needed
4229 anymore. Affected file silcd/idlist.[ch].
4231 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4232 to use internally the SilcHashTable. The new ID Cache is a lot
4233 faster than the old one. Some of the ID Cache interface was also
4234 rewritten and obsolete and stupid functions were removed.
4236 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4238 * Added entry_count field to the SilcHashTable to keep the number
4239 of the entries in the table. Implemented the function
4240 silc_hash_table_rehash. Added new function
4241 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4243 Fixed a minor bug in silc_hash_table_free.
4245 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4246 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4247 into the lib/silcutil/silcutil.[ch].
4249 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4251 * Implemented a collision resistant hash table into the
4252 lib/silcutil/silchashtable[ch]. See the header and the source
4253 for the SilcHashTable API.
4255 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4257 * Merged dotconf version 1.0.2 into lib/dotconf.
4259 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4261 * Do not compile anything in lib/silcsim/* if the SIM support
4262 is not enabled. The tree should now compile without problems
4265 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Compiled the SILC under cygwin. Compiled and tested briefly
4268 without problems. More tests needed. The SIMs didn't compile
4271 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4273 * Fixed possible crash in silc_get_username in the
4274 lib/silcutil/silcutil.c.
4276 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Fixed a va_arg in silc/client_ops.c.
4280 * Oops, RC5 routines were named AES and caused some problems
4281 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4283 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Added new SilcIDIP structure into the lib/silccore/id.h and
4286 replaced the old `ip' fields from all SILC ID's to that type.
4287 This is a step towards IPv6 support.
4289 The silc_id_get_len takes now the ID as an extra argument.
4290 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4291 both IPv4 and IPv6 based ID's.
4293 The affected files are lib/silccore/id.[ch] and other files
4294 around the tree using these routines.
4296 * Removed the ID length arguments in server from various
4297 silc_server_send_notify_* routines -> they are not needed
4300 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * Fixed memory leak in silc_encode_pem_file in the file
4303 lib/silcutil/silcutil.c.
4305 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4307 * Check minor version as well in the SKE. Affected files are
4308 silcd/protocol.c and lib/silcclient/protocol.c.
4310 * Added --identifier option to the server so that an identifier
4311 can be when creating the public key for the server. Affected
4312 file is silcd/silcd.c.
4314 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4315 lib/silccrypt/silcpkcs.c.
4317 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Register default ciphers and stuff when using -C option with
4320 the server. Affected file sildc/silcd.c.
4322 * Put back the servers public key filename format, it is better
4323 than the new one. For now, the client keys are saved with the
4324 new filename format. The affected file silc/client_ops.c.
4326 * Implemented the Cipher API for the rest of the ciphers that
4327 did not implement it or implemented it the wrong way.
4329 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4331 * Register default ciphers and stuff when using the -S option
4332 in the client. Affected file silc/silc.c. Same also when
4333 creating new key pair with -C option.
4335 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Fixed the silc_verify_public_key client operation function to
4338 save the public keys differently. The fingerprint is now
4339 used as filename and not the hostname. This way also the
4340 client keys are saved uniquely and not with hostnames. The
4341 affected file is silc/client_ops.c.
4343 * Trimmed the silc_hash_fingerprint function to remove extra
4344 whitespaces from the end of the fingerprint. The affected
4345 file is lib/silccrypt/silchash.c.
4349 * Added silc_cipher_register_default function to register all
4350 default ciphers. It can be used when configuration files
4351 does not exist and the application does not want any specific
4352 ciphers in any specific order.
4354 The SilcDList is now used as silc_cipher_list dynamically
4355 allocated cipher list. Removed the static list all together
4356 and now all ciphers must be allocated to the dynamic list.
4357 The silc_cipher_alloc routine was changed to check only the
4360 All silc_cipher_* routines that used to return int returns
4363 The affected files lib/silccrypt/silccrypt.[ch].
4365 * The same thing was done to silc_hash_* as for silc_cipher_*
4366 routines. Affected files lib/silccrypt/silchash.[ch].
4368 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4369 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4370 Added also silc_pkcs_[un]register[_default] functions.
4371 Removed the data_context from the PKCS API.
4373 * Added silc_hmac_register_default function to register default
4374 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4375 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4376 to unregister all hmacs at once.
4378 * Register the default ciphers, hash functions, PKCSs and HMACs
4379 if client's configuration file does not exist. The affected
4382 * The client did not load the hash functions from the SIM
4383 modules at all. Added support for this. Affected file is
4384 silc/clientconfig.c.
4386 * When decoding public key with silc_pkcs_public_key_decode, check
4387 the supported algorithm only if PKCS are registered. Affected
4388 file lib/silccrypt/silcpkcs.c. The same was done with the
4389 silc_pkcs_private_key_decode.
4391 * Fixed the SILC List routines to keep the list always in order.
4392 It used to change the list's order when traversing the list but
4393 not it preserves the order. Affected file lib/trq/silclist.h.
4395 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4397 * Added the client library to use the SilcSocketConnection's
4398 reference counter (by silc_socket_dup) to prevent the bug that
4399 the socket object may be freed underneath async operation.
4401 * The name resolv library checking fixes in the configure.in.pre.
4404 * Created new version of the protocol drafts for future
4405 development. The -03 drafts are the ones that will be changed
4406 in the trunk now and the -02 will remain as they are.
4408 * Send list of CUMODE notifys to the router when announcing
4409 the channel users to the router. Affected file silcd/server.c.
4410 If the router receiving channel founder CUMODE for a channel
4411 that already has channel founder it will send CUMODE notify
4412 to the sender to remove the channel founder rights from the
4413 announced client. Affected file silcd/packet_receive.c.
4415 * The CUMODE notify may now use Server ID as well as the entity
4416 who changes the mode. Updated protocool specs.
4418 * Updated INSTALL and README files.
4420 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4422 * New web pages in the http://silc.pspt.fi. The pages was
4427 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4429 * Implemented the [DenyConnectin] config section in the server.
4430 Added silc_server_config_denied_conn to check whether incoming
4431 connection is denied. Affected file silcd/serverconfig.[ch].
4433 * Do not check the ports when checking the incoming configuration
4434 data if the port is 0, meaning any. Affected file is
4435 silcd/serverconfig.c.
4437 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4439 * Fixed buffer overflow in silc_string_compare in the file
4440 lib/silcutil/silcutil.c.
4442 * Fixed double free in silc_server_command_leave in the file
4445 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4447 * Fixed the version checking in the server. Affected file is
4450 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Fixed the configuration data fetching when accepting new
4453 connections in the server. Affected file silcd/server.c.
4455 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4457 * Added `sender_entry' argument to the function
4458 silc_server_packet_relay_to_channel so that we can check
4459 whether some destination actually belongs to the same route
4460 the sender belongs (ie, we must not resend the packet to the
4461 sender). Affected file silcd/packet_send.[ch].
4463 * Added `servername' field to the SilcClientEntry in the server
4464 to hold the name of the server where client is from. Affected
4465 file is silcd/idlist.h.
4467 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * Moved the channel message encrypting in the router betwen
4470 router connections from silc_server_channel_message to the
4471 silc_server_packet_relay_to_channel since we want to check
4472 whether we have anybody channel before encrypting anything.
4473 Affected files silcd/packet_[receive/send].c.
4475 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4477 * Fixed the [AdminConnection] server config section to support
4478 multiple entries. Affected file silcd/serverconfig.c.
4480 * Added support into the server to check the validity of the
4481 incoming connection before executing any KE or authentication
4484 * The connection configuration is now saved to the KE and
4485 connection auth protocol contexts and not fetched anymore in
4486 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4488 * The local hosts listenning address and port is also resolved
4489 now when starting the server. We want to have the socket object
4490 to include the real address and port for the listener. Added
4491 new function silc_net_check_local_by_sock into the files
4492 lib/silcutil/silcnet.[ch].
4494 * Fixed a broadcast bug in server -> do not broadcast if we
4497 * Fixed a routing bug. Do not route broadcast packets ever.
4498 Broadcast packets must be processed always and not routed since
4499 they may be destined to some other host than yourself and thus
4500 would get routed without no good reason. Affected file is
4503 * Added function silc_server_config_is_primary_route to check
4504 whether primary router connection has been configured (a router
4505 configuration that we are initiating). If there is not, we
4506 will assume that there is only two routers in the SILC network
4507 and we will use the incoming router connection as our primary
4508 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4510 * Changed the order of the broadcasting. Broadcast _after_ the
4511 packet has been processed not before. Affected file is
4514 * Fixed a [ClientConnection] parsing bug. The port was never
4515 parsed correctly thus resulting to port 0. Affected file
4516 silcd/serverconfig.c.
4518 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4519 argument and did not set the broadcast packet flag. Affected
4520 file silcd/packet_send.c. Fixed same bug in the function
4521 silc_server_send_notify as well.
4523 * If we receive NEW_ID packet for our own ID in the server, ignore
4526 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Removed the nickname from the Private Message Payload.
4531 Updated the code and the protocol specs.
4533 * Updated protocol specs for submitting to the IETF.
4535 * Tweaked the Random Number Generator a bit. Affected file
4536 lib/silccrypt/silcrng.c. Exported a new function
4537 silc_rng_[global]_add_noise which can be used to add more
4540 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4542 * Do not parse packets with different timeout when protocol
4543 is active -> may cause problem with rekey. Affected file
4546 * When server receives signoff notify it must not create
4547 new channel key if the client is on any channels since the
4548 sender of the signoff notify will create it.
4550 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4552 * Added printing of error messages during SKE protocol from the
4553 failure packet sent by server during SKE. Affected file
4556 * Removed the client's failure_callback handling with timeout
4557 and handle it immediately when received.
4559 * The SKE library returned wrong type in SUCCESS and FAILURE
4560 packets. They must be 32 bit MSB not 16 bit MSB.
4562 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4564 * Ok, rewrote the logic of the re-key and now it seems to work.
4565 I tested it on high traffic with frequent re-keys without
4566 problems. Added hmac_receive (and renamed hmac to hmac_send)
4567 in SilcClientConnection in lib/silcclient/client.h and
4568 in SilcIDListData in silcd/idlist.h. Also, removed the
4569 SilcPacketParserContext's cipher and hmac fields as they are
4570 not needed anymore and actually caused some problems when
4571 the ciphers and hmac's changed underneath the packet parser.
4573 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4575 * If re-key protocol is active then process the incoming packets
4576 synchronously since we must assure that icoming packets encrypted
4577 with the old key is processed before the new keys is set to
4578 use. This is true other packets than for REKEY packets.
4579 Affected file silcd/server.c. The same was done to client library
4580 as well, affected file lib/silcclient/client.c.
4582 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4584 * Fixed bug in client and server to accept the force send if
4585 the packet is send from silc_[server/client]_packet_process
4586 function. Otherwise the packets are never delivered, oops.
4588 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Disable force sending of packets when REKEY protocol is active.
4591 We must assure that no packet is sent directly when rekey is
4592 performed. All packets must be sent through packet queue.
4593 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4594 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4595 function is silc_[server/client]_packet_send_real to check
4598 * Replaced the SIM paths from example config files to
4599 /usr/local/modules. Also, make install creates now
4600 /usr/local/silc/logs directory to hold all the SILC server
4603 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Made the configure.in.pre work on Solaris. Patch by salo.

4614 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4616 * When MAC computation fails the silc_packet_decrypt returned 0
4617 even though it was supposed to return -1. Fixed this. The
4618 affected file is lib/silccore/silcpacket.c.
4620 * Do not replace the config files in /etc/silc (in make install)
4621 if they already exist. Affected file ./Makefile.am.
4623 * Do not send re-key packets immediately but through packet queue.
4624 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4626 * Changed silc_net_check_host_by_sock to return FALSE if the
4627 IP/DNS could not be resolved. Though, it returns the IP address
4628 now even if it could not resolve it (but returns also FALSE).
4629 Affected file lib/silcutil/silcnet.[ch].
4631 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4633 * Added silc_pkcs_decode_identifier to decode the public key's
4634 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4635 Added also silc_pkcs_free_identifier. Added also new context
4636 SilcPublicKeyIdentifier.
4638 * Added -S option to the silc client. It is used to dump the
4639 contents of the specified public key file.
4641 * Changed the PKCS api to return the public key length when
4642 setting the public key.
4644 * Fixed a fatal bug in the public and private key file loading.
4645 Affected file lib/silccrypt/silcpkcs.c.
4647 * Execute the packet parsing for client with zero (0) timeout
4648 if the protocol is active. Affected file silcd/server.c.
4650 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4652 * Made the key generation options to the silcd program. Added
4653 -C option, equivalent to client's option.
4655 * Added new [ServerKeys] config section to the server. It
4656 configures the server's public and private key.
4658 * Defined generic Public Key Payload into the protocol
4659 specification to send specific type of public keys and
4662 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4663 public key or certificate.
4665 * Implemented the GETKEY command to the server and to the
4666 client library and on user interface.
4668 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4670 * Made preliminary `make install' work.

4699 SilcClientConnection structure; not needed. Affected file is
4700 lib/silcclient/client.h.
4704 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4706 * Do not ask whether user wants to use the negotiated private key
4707 for private messages, just use it. Affected file is
4708 silc/local_command.c.
4710 * Added `send_enc_key' and `enc_key_len' fields to the
4711 SilcIDListData structure since they are needed in the re-key

4735 * Changed _ALL_ unsigned long and unsigned int to uint32,
4736 unsgined short to uint16 in the source tree.
4738 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4739 not handle clients that has entry->data.registered == FALSE.
4740 They are not in the network anymore. Affected file is
4743 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4757 implemnted the printing of the SERVER_SIGNOFF info to the
4758 application. Affected file silc/client_ops.c.
4760 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4761 if the deleting was successful. Affected file silcd/idlist.[ch].
4763 * Added support for public key authentication in the connection
4764 authentication protocol in the client library. Affected file
4765 lib/silcclient/protocol.c.
4767 * Changed the server's silc_idlist_get_clients_by_* interface
4768 to support already allocated array so that new entries may be
4769 added to pre-allocated array. Affected file silcd/idlist.[ch].
4770 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4771 and command replies.
4773 * All command reply functions in the server now calls the
4774 pending command callback even if error occured. This way the
4775 error will be delivered to the client as well. Affected files
4776 silcd/command.c and silcd/command_reply.c.
4778 * Fixed INFO command to return local server's info if no server
4779 was provided. Affected file lib/silcclient/command.c.
4781 * Removed RESTART command for good. Updated the code and the
4784 * Rewrote parts of the task system. It is a bit simpler now.
4785 Removed unsued task priorities. The affected files are
4786 lib/silcutil/silctask.[ch].
4788 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4790 * Moved the USERS printing from the library to the application.
4791 Affected files lib/silcclient/command.c and silc/client_ops.c.
4793 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Added channel key re-key support. The re-key is perfomed
4798 only by the router and is done once in an hour. Added `rekey'
4799 field to the SilcChannelEntry in the server. Affected files
4800 silcd/server.c and silcd/idlist.h.
4802 * Added silc_task_unregister_by_context into the file
4803 lib/silcutil/silctask.[ch].
4805 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4807 * Added SILC_UMODE_GONE mode to indicate when the client is not
4808 present in the SILC network. Added also support to the local
4809 command AWAY that will set this mode. Added support of showing
4810 "xxx is gone" in WHOIS command. The USERS command shows the
4811 gone status as well.
4813 * Fixed setting server and router operator privileges in the
4814 server's UMODE command. Affected file silcd/command.c.
4816 * Merged the SKE KE1 and KE2 payloads into one payload. The
4817 new KE payload is equivalent to the old KE2 payload.
4819 Cleaned up the SKE Start Payload parsing. It now uses the
4820 simple buffer unformatting to do the parsing. A lot faster
4823 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4824 to the SKE that is used to indicate whether both of the SKE
4825 parties should perform authentication. By default only the
4826 responder performs authentication. By setting this flag also
4827 the initiator must do authentication. By default it is unset
4828 since in normal SKE case, client to server connection, only
4829 the responder should do authentication. When doing SKE between
4830 two clients both should perform authentication. Updated the
4831 code and the protocol specs.
4833 * A little fix to IDENTIFY command in the server. Search the
4834 client first by hash not nickname. Affected file is
4837 * Fixed the silc_client_close_connection to support closing
4838 the client to client connections wihtout deleting too much
4839 data. Affected file lib/silcclient/client.c.
4841 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4842 are received if protocol used to be active but is not anymore
4843 the application would crash due to NULL pointer dereference.
4844 Affected files silcd/server.c and lib/silcclient/client.c.
4846 * Added `hash' field to the SilcClientConnection to include
4847 the hash function negotiated in the SKE protocol.
4849 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4850 to set the channel founder authentication data. A client can
4851 claim the founder rights later by providing the authentication
4852 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4853 This way the channel founder can regain the channel founder
4854 privileges even it is left the channel. This works only on
4855 local server and the client must be connected to the same
4856 server to be able to regain the founder rights. Updated the
4857 protocol specs accordingly.
4859 Added support to the CMODE command in the client to set the
4860 founder auth data. Read the README to see how to set it.
4862 Added support to the CUMODE command to claim the founder
4863 rights. Read the README to see how to do it.
4865 Added support for the founder authentication to the Channel
4866 Entry in the server. Affected file silcd/idlist.h.
4868 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4869 server's CMODE command. Affected file silcd/command.c.
4871 * Added the following new functions into lib/silccore/silcauth.[ch]:
4872 silc_auth_get_method and silc_auth_get_data.
4874 * The server now saves the remote hosts public key to the
4875 SilcIDListData pointer. Affected file silcd/protocol.c.
4877 * The normal server now does not remove the channel entry from
4878 the cache if the founder authentication data is set. It used
4879 to remove it if the founder was the last one on the channel on
4880 the server and left the channel. The auth data is saved and
4881 if the channel is re-joined later the old entry is used with
4882 the old auth data. Affected files silcd/command_reply.c and
4885 * Removed the `pkcs' field from the SilcIDListData structure
4886 in the server; it is not used. Affected file silcd/idlist.h.
4888 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4890 * Fixed packet processing on slow links. Partial packets were
4891 never re-processed because the incoming data buffer was cleared
4892 by the application. Application must not directly clear the
4893 sock->inbuf, the packet processing routines handle it. Fixed
4894 this in client library and in server.
4896 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4898 * Fixed the WHOIS and IDENTIFY send reply function to really
4899 check whether to send list or just one entry. Affected file
4902 * Cleaned up the LEAVE command's channel key distribution. The
4903 affected file silcd/command.c.
4905 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4906 can enforce the channel mode as well. In that case the ID
4907 includes the ID of the server. The code now enforces the
4908 mode change if the router have different mode than the server.
4910 * The notify client operation with CMODE_CHANGE notify can now
4911 return NULL client_entry pointer if the CMODE was not changed
4912 by client. Application must check for this.
4914 * Added <Server ID> argument to INFO command to support server
4915 info fetching by Server ID.
4917 * Added silc_server_announce_get_channel_users to get assembled
4918 packets of channel users of the specified channel. Affected
4919 file silcd/server.[ch].
4921 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4922 was freed underneath the ID Cache.
4924 * Re-announce clients when the server received CHANNEL_CHANGE
4925 notify from the router. Affected file silcd/packet_send.c.
4927 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4929 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4930 crashed since it did not handle the fact that there is no cipher
4931 called "3" and didn't check the error condition. Now fixed.
4933 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4934 flag. It can be used to send message requests.
4936 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4938 * Implemented the RESTART command in the client.
4940 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4941 notice type messages. Added notice printing to the user
4944 * The channel keys are not re-generated if the channel's mode
4945 is PRIVKEY, ie private key on the channel exists. Affected
4946 files silcd/server.c and silcd/command.c.
4948 * Fixed a little bug in channel message delivery when channel
4949 private keys are set in the server. Affected file is
4950 silcd/packet_send.c.
4952 * Changed the setting on channel->on_channel = TRUE from the
4953 silc_client_save_channel_key to the JOIN command reply. The
4954 key payload is not received if the private channel key is set.
4955 Affected file lib/silcclient/command_reply.c and the
4956 lib/silcclient/client_channel.c.
4958 * When the CMODE_CHANGE notify is sent and the channel private
4959 key mode is removed the channel key must be re-generated in
4960 other cells as well. Added this support for the router in the
4961 silcd/packet_receive.c.
4963 * Added new local command NOTICE to send notice message on
4964 channel. Affected file silc/local_command.[ch].
4966 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4968 * Added new local command ME to the client. It is used to send
4969 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4970 some action. Affected file silc/local_command.[ch].
4972 * Changed channel_message and private_message client operations
4973 to deliver the message flags to the application. Added also
4974 the `flags' arguments to the silc_client_send_channel_message
4975 and silc_client_send_private_message functions. Affected file
4978 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4980 * Redefined the Private Message Payload to support private message
4981 keys and to support the new private message flags. Updated
4982 the protocol specs. Flags makes it possible to have for example
4983 CTCP style messages.
4985 * Added new type SilcPrivateMessagePayload and defined an API
4986 for it in the lib/silcclient/silcprivate.[ch].
4988 * Tested private message private keys successfully. Tested the
4989 private message key set, unset and list commands with the new
4992 * Redefined the Channel Message Payload to include the channel
4993 message flags (equal with private message flags) to support
4994 for example CTCP style messages.
4996 * Defined some of the message (for channel and private message)
4997 flags. Updated the protocol specs and added the flags to the
4998 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5000 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5002 * Added SilcKeyAgreementStatus type to the key agreement routines
5003 to indicate the current status and error if one occured.
5004 The status types are defined in the lib/silcclient/silcapi.h.
5006 * Added new local command KEY that is used to set and unset private
5007 keys for channels, set and unset private keys for private messages
5008 with remote clients and to send key agreement requests and
5009 negotiate the key agreement protocol with remote client. The
5010 key agreement is supported only to negotiate private message keys,
5011 it currently cannot be used to negotiate private keys for channels,
5012 as it is not convenient for that purpose.
5014 * Fixed a minor pending callback setting bug in the function
5015 silc_client_get_client_by_id_resolve, now the function works.
5016 Affected file lib/silcclient/idlist.c.
5018 * Added function silc_net_get_local_port to get local bound
5019 port by socket. Added to lib/silcutil/silcnet.[ch].
5021 * Added `sockets' and `sockets_count' fields to the SilcClient
5022 object. They hold the sockets of the listenning sockets in
5023 the client. Listenning sockets may be for example the key
5024 agreement server. Affected file lib/silcclient/client.[ch].
5025 Added functions the silc_client_add_socket and the
5026 silc_client_del_socket. They are exported to the application
5029 * Added ~./silc/clientkeys to support other client's public keys.
5031 * Renamed verify_server_key client operation to verify_public_key
5032 and added one argument to indicate the type of the connection
5033 (server, client etc.).
5035 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5037 * Added silc_server_connection_auth_request to handle the
5038 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5039 silcd/packet_receive.[ch].
5041 * Added silc_server_send_connection_auth_request into the
5042 silcd/packet_send.c to send the connection auth request packet.
5044 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5047 * Fixed the public key authentication in responder side in the
5048 server. The `auth_data' pointer includes the SilcPublicKey
5049 not the path to the public key. Affected file silcd/protocol.c.
5051 * Implemented the public key authentication in the initiator side
5052 in the server. Affected file silcd/protocol.c.
5054 * Removed the [RedirectClient] config section from the server
5055 configuration. Is not needed and I don't want to implement it.
5057 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Cleaned up the CMODE command in the server. It now works
5060 correctly and supports all the modes defined in the protocol.
5061 Affected file is silcd/command.c.
5063 * Added `hmac_name' field to the SilcChannelEntry in the server
5064 to hold the default HMAC of the channel. It can be set when
5065 creating the channel (with JOIN command). Affected files
5068 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5069 type to indicate the change of the current cipher and hmac
5070 on the channel. Client can safely ignore the <cipher> argument
5071 (if it chooses to do so) since the CHANNEL_KEY packet will
5072 force the channel key change anyway. The <hmac> argument is
5073 important since the client is responsible of setting the new
5074 HMAC and the hmac key into use.
5076 * Fixed the CMODE command in the client library as well.
5078 * Tested CMODE command in router environment successfully.
5080 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5082 * Show the version of the remote client (or server) when connecting
5083 to the server. It is logged to the log file. Affected file
5084 is silcd/protocol.c.
5086 * Fixed the KILLED notify handling in the client library. The
5087 client must be removed from all channels when receiving the
5090 Also, do not remove the client entry when giving the KILL
5091 command but when the KILLED notify is received.
5093 * Removed silc_idlist_find_client_by_nickname from the server.
5094 Not needed anymore. Affected files silcd/idlist.[ch].
5096 * Implemented the CHANNEL_CHANGE notify type handling to the
5097 server. Affected file silcd/server.c.
5101 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5103 * Added silc_server_send_notify_invite to send the INVITE
5104 notify between routers.
5106 * Implemented the INVITE command correctly to the server.
5108 * Implemented the INVITE notify type handling in the server.
5110 * Implemented the INVITE command to the client library and on the
5113 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5115 * Added function silc_server_get_client_resolve to find the
5116 client entry by ID from all ID lists and then resolve it
5117 (using WHOIS) if it cannot be found. Affected file is
5120 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5122 * Implemented the BAN command to the client library.
5124 * The JOIN command in the server now checks the invite list
5127 * Changed the silc_command_reply_payload_encode_va and the
5128 silc_command_payload_encode_va to support that if argument is
5129 NULL it ignores and checks the next argument. Affected file
5130 lib/silccore/silccommand.c.
5132 * Added silc_server_send_notify_ban to send the BAN notify
5133 type between routers.
5135 * Chaned the silc_notify_payload_encode to support that if
5136 argument is NULL it ignores and checks the next argument.
5137 Affected file lib/silccore/silcnotify.c.
5139 * Tested ban lists in router environment successfully.
5141 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5143 * Implemented BAN command to the server, in silcd/command.[ch].
5145 * Removed the BAN and INVITE_LIST modes from the CMODE command
5148 * Added function silc_string_match to regex match two strings.
5149 Affected files lib/silcutil/silcutil.[ch].
5151 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5153 * Redefined parts of the SilcChannelEntry in the server to support
5154 the new ban and invite lists.
5156 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5158 * Redefined the INVITE command. The same command can be used to
5159 invite individuals to the channel but also to manage the invite
5160 list of the channel (to add to and remove from the invite list).
5161 Updated the protocol specs.
5163 * Added new command SILC_COMMAND_BAN that can be used to manage
5164 the ban list of the channel. Updated the protocol specs.
5166 * Removed the channel modes: the SILC_CMODE_BAN and the
5167 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5168 in the CMODE command. The equivalent features are now available
5169 using INVITE and BAN commands. Updated the protocol specs.
5171 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5172 in the network about change in the current ban list. The notify
5173 type is not used by the client.
5175 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5176 support the invite lists.
5178 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * Added new function silc_string_regexify that converts string
5181 including wildcard characters into regex string that can
5182 be used by the GNU regex library. Added into the file
5183 lib/silcutil/silcutil.[ch].
5185 Added silc_string_regex_combine to combine to regex strings
5186 into one so that they can be used as one regex string by
5187 the GNU regex library. Added into the file
5188 lib/silcutil/silcutil.[ch].
5190 Added silc_string_regex_match to match two strings. It returns
5191 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5193 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5195 * Imported GNU regex to the soruce tree into lib/contrib.
5196 Fixed some compiler warning from the regex.c.
5198 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5200 * Fixed MOTD command in the server to work in router environment.
5202 * Fixed the MOTD command in the client library to support
5203 the server argument in the command.
5205 * Added `nickname_len' argument to the silc_idlist_add_client
5206 in the server, as the `nickname' argument may be binary data
5209 * Added silc_idlist_get_channels to return all channels from
5212 * Implemented LIST command to the server. Affected file is
5215 * Implemented the LIST command to the client library and on the
5218 * Added [<user count>] argument to the LIST command reply.
5219 With private channels the user count is not shown.
5221 * Updated TODO and README.
5223 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * The client entry's data.registered must be TRUE even with
5226 global client entry on global client list. The data.registered
5227 is used to check whether the client is anymore in the network,
5228 for example with WHOWAS command so it must be valid.
5230 * Fixed the WHOWAS command in the server. It now actually works
5231 in router environment. Added function into silcd/command_reply.c
5232 silc_server_command_reply_whowas_save.
5234 * Added silc_idlist_purge function to the silcd/idlist.c
5235 to periodically purge the ID Cache.
5237 * Fixed INFO command in the server. It works now in router
5238 environment. Added <server name> argument to the INFO command
5239 reply. Updated the protocol specs.
5241 * Fixed minor bug in silc_idcache_purge to not purge if the
5242 expire value is zero.
5244 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5245 they were buggy because of the WHOWAS information.
5247 * Fixed local command MSG to handle the async resolving of
5248 the remote client properly. It used to fail the first MSG.
5249 Affected file silc/local_command.c.
5251 * Added `data_len' field to SilcIDCache context.
5253 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5255 * Update TODO. Todo in commands in the server.
5257 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5259 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5260 used by routers as broadcast packet to inform other routers
5261 about the changed user mode.
5263 Implemented the notify handling in the server. Affected file is
5264 silcd/packet_receive.c. Added the function
5265 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5267 * Added new generic Channel Payload and deprecated the New Channel
5268 Payload. The New Channel Payload is now the generic Channel
5271 * Added new argument `mode' to the silc_server_send_new_channel
5272 as it is required in the Channel Payload now.
5274 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5275 and created a new and real SilChannelPayload to represent the
5276 new generic Channel Payload. Implemented the encode/decode
5277 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5279 * Added silc_server_get_client_channel_list to return the list
5280 of channels the client has joined for WHOIS command reply.
5281 Affected file silcd/server.[ch].
5283 * Implemented the channel list sending in the WHOIS command reply
5284 in server and in the client.
5286 Implemented the channel list displaying on the user interface
5287 as well. Affected file silc/client_ops.c.
5289 * Added silc_channel_payload_parse_list to parse list of Channel
5290 Payloads. It returns SilcDList list of SilcChannelPayloads.
5291 Client for example can use this function to parse the list of
5292 channels it receives in the WHOIS command reply. The caller
5293 must free the list by calling silc_channel_payload_list_free.
5294 Affected files lib/silccore/silcchannel.[ch].
5296 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Added one new argument <user mode> to the WHOIS command reply
5299 to return the mode of the user in SILC. Updated the protocol
5302 Implemented it to the server and client.
5304 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5306 * Fixed the mode printing on the user interface on joining.
5307 Affected file silc/client_ops.c.
5309 * Implemented the UMODE command and user modes in general to the
5310 client library and to the user interface.
5312 * Implemented the UMODE command to the server.
5314 * The server now sends UNKNOWN_COMMAND error status if client sends
5315 unknown command. Affected file silcd/command.c.
5317 * All server commands now handle the command identifier the right
5318 way when sending the command reply to the client. The client can
5319 use to identify the command replies with the identifier.
5321 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5323 * Added silc_server_get_client_route to resolve the route to
5324 the client indicated by the client ID. Affected file is
5327 * Added silc_server_relay_packet as general function to relay
5328 packet to arbitrary destination. This deprecates functions
5329 like _send_private_message_key, _relay_notify etc. Affected
5330 file is silcd/packet_send.[ch].
5332 Removed silc_server_send_key_agreement,
5333 silc_server_send_private_message_key and
5334 silc_server_packet_relay_notify functions from the file
5335 silcd/packet_send.[ch].
5339 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5340 server. Affected file silcd/packet_receive.[ch].
5342 * Implemented the KILL command to the client. Implemented the
5343 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5344 Affected files lib/silcclient/command[_reply].c and
5345 lib/silcclient/client_notify.c. Implemented the KILL notify
5346 printing in the user inteface.
5348 * Fixed a lot silc_parse_nick memory leaks from the client
5349 library in the file lib/silcclient/command.c.
5351 * Changed the silc_server_send_notify_on_channels's `sender'
5352 argument from SilcSocketConnection to SilcClientEntry to
5353 check the sender as entry and not as connection object and not
5354 to send to the client provided as argument. The affected file
5355 is silcd/packet_send.[ch].
5357 * The notify packets that are destined directly to the client used
5358 to not to be processed by the server. Now changed that and the
5359 server processes all notify packets. After relaying the packet
5360 to the client the notify packet is processed in the server.
5362 * The silc_server_free_client_data now checks whether there is
5363 pending outgoing traffic for the client and purges the data to
5364 the network before removing the client entry.
5366 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5369 an client is killed from the SILC Network. Updated the protocol
5372 Added new function silc_server_send_notify_killed to the
5373 silcd/packet_send.[ch].
5375 * Added function silc_server_packet_relay_notify to relay notify
5376 packets that are destined directly to a client. In this case
5377 the server does not process the notify packets but merely relays
5378 it to the client. Affected file silcd/packet_send.[ch].
5380 Added also silc_server_packet_process_relay_notify to check
5381 whereto relay the notify. Affected file is
5382 silcd/packet_receive.[ch].
5384 * Implemented the KILL command to the server.
5388 * Added the backup schema desgined last fall to the protocol
5389 specs for everyone to see. The specification is in the
5390 *-spec-xx.txt draft and the packet type definitions for the
5391 backup routers is in *-pp-xx.txt draft. Thusly, added also
5392 new packet type SILC_PACKET_CELL_ROUTERS.
5394 * A big security problem in the implementation discovered. The
5395 signoff of an client did not cause new channel key generation
5396 which it of course should've done. The channel keys must be
5397 always re-generated when client leaves (or signoffs) the channel.
5398 The silc_server_remove_from_channels funtion now handles
5399 the channel key re-generation.
5401 * Added `sender' argument to the silc_server_send_notify_on_channels
5402 to not to send the client provided as argument. Affected file
5403 silcd/packet_send.[ch].
5405 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5407 * Implemented OPER and SILCOPER commands into the server and
5410 * Added silc_auth_verify and silc_auth_verify_data to verify
5411 the authentication directly from the authentication payload.
5412 It supports verifying both passphrase and public key based
5413 authentication. Affected file lib/silccore/silcauth.[ch].
5415 * Added `hash' field to the SilcIDListData structure. It is the
5416 hash negotiated in the SKE protocol. Affected file is
5419 * Slight redesigning of the SilcAuthPayload handling routines.
5420 Do not send SilcPKCS but SilcPublicKey as argument.
5422 * Implemented the public key authentication support to the
5423 serverconfig. The public key is loaded from the provided path
5424 and saved as authentication data to void * pointer. Thus,
5425 changed the unsigned char *auth_data to void *auth_data;
5427 * Fixed SHUTDOWN command to send the reply before the server
5428 is shutdown. :) Affected file silcd/command.c.
5430 * Fixed fatal bug in CONNECT command. The hostname was invalid
5431 memory and server crashed. Affected file silcd/command.c.
5433 * Fixed fatal bug in CLOSE command. The server_entry became
5434 invalid but was referenced later in the command. Affected file
5437 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5439 * Fixed fatal bug in failure packet handling. Server ignored
5440 the failure and thus crashed when it came.
5444 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5446 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5447 that the command may be executed only once in (about) 2 seconds.
5448 The old SILC_CF_LAG flag is same but allows command bursts up
5449 to five before limiting.
5451 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5452 server code. Various commands now includes the CF_LAG_STRICT
5453 flag to disallow any kind of miss-use of the command.
5455 * Fixed the silc_buffer_unformat to not to allocate any data
5456 if the length of the data is zero. It used to allocate the
5457 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5459 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5461 * Changed the format of AdminConnection configuration section
5462 in the server. Added username of the admin to the format.
5463 Affected files silcd/serverconfig.[ch].
5465 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5466 to return admin configuration data by host, username and/or
5469 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5471 * Implemented WHOWAS command to the server. Added the functions:
5473 silc_server_command_whowas_parse,
5474 silc_server_command_whowas_send_reply,
5475 silc_server_command_whowas_from_client and
5476 silc_server_command_whowas_from_server
5478 * Added <Client ID> argument to the WHOWAS command reply. Updated
5479 the protocol specs accordingly.
5481 * Implemented WHOWAS command and command_reply to the client
5484 Implemented the WHOWAS printing on the user interface.
5486 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5488 * Added new argument to the WHOWAS command reply, the real name.
5489 It is an optional argument. Updated the protocol specs.
5491 * Added SilcIDCacheDestructor callback that is registered when
5492 the SilcIDCache is allocated. The callback is called when
5493 an cache entry in the ID Cache expires, or is purged from the
5494 cache. Added into lib/silccore/idcache.[ch].
5496 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5497 to destruct the client entries when the cache entry expires.
5498 Other ID Cache's in server and in the client library ignores
5501 * If the ID Cache entry's `expire' field is zero then the entry
5502 never expires. Added boolean `expire' argument to the
5503 silc_idcache_add function in the lib/silccore/idcache.[ch].
5504 If it is TRUE the default expiry value is used.
5506 * Added silc_server_free_client_data_timeout that is registered
5507 when client disconnects. By default for 5 minutes we preserve
5508 the client entry for history - for WHOWAS command.
5510 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * Added support to the server to enforce that commands are not
5513 executed more than once in 2 seconds. If server receives
5514 commands from client more frequently, timeout is registered
5515 to process the commands. Affected file silcd/command.c.
5516 Added new function silc_server_command_process_timeout.
5518 * Changed NICK_NOTIFY handling in client library to check that
5519 if the client's nickname was changed, so there is no need to
5520 resolve anything from the server.
5522 * Removed error printing from the WHOIS and IDENTIFY commands.
5523 If error occurs then it is ignored silently in the client library.
5524 The application, however, may map the received error to
5525 human readable error string. The application currently maps
5526 the NO_SUCH_NICKNAME error to string.
5528 * Made the command status message public to the application. Moved
5529 them from lib/silcclient/command_reply.c to
5530 lib/silcclient/command_reply.h. The application can map the
5531 received command status to the string with the
5532 silc_client_command_status_message function.
5534 * Added check to the server to check that client's ID is same
5535 as the Source ID in the packet the client sent. They must
5538 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5540 * Added dist-bzip hook to the Makefile.am to make bzip2
5541 compressed distributions.
5543 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5545 * Server now enforces the maximum length for the nickname and
5546 the channel as protocol specification dictates. 128 bytes for
5547 nickname and 256 bytes for channel name.
5549 * Moved the WHOIS printing to the application. The client libary
5550 does not print out the WHOIS information anymore, the application
5551 must do it. Renamed silc_client_command_reply_whois_print to
5552 the silc_client_command_reply_whois_save.
5554 The client's idle time is also sent to the application now, and
5555 the idle is shown on screen.
5557 * Added silc_client_command_reply_identify_save to save the
5558 received IDENTIFY entries.
5560 * Do not check for channel private keys in message sending and
5561 reception if the channel does not have the PRIVKEY mode set.
5562 Affected file lib/silclient/client_channel.c.
5564 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5566 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5567 just surfaced after chaning the JOIN procedure.
5569 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5571 * Added silc_client_get_clients_by_list to get client entries
5572 from Client ID list, that is returned for example by JOIN
5573 and USERS command replies. The application should use this
5574 function for example when JOIN command reply is received to
5575 resolve the clients already on the channel (library does not
5576 do that anymore as USERS command reply is not used in the JOIN
5577 procedure anymore). Affected files lib/silcclient/silcapi.h and
5578 lib/silcclient/idlist.c.
5580 * JOIN command reply and USERS command reply returns now SilcBuffer
5581 pointers instead of unsigned char pointers when returning
5582 the client list and mode list.
5584 * Added <Client ID> argument to the JOIN command reply, mainly
5585 for the server to identify for which client the command was
5586 originally sent. Updated protocol specs accordingly.
5588 * Added SilcDlist private_key pointer to the SilcChannelEntry
5589 in the client to support the channel private keys. Affected
5590 file is lib/silcclient/idlist.h.
5592 * Added SilcChannelPrivateKey argument to the function
5593 silc_client_send_channel_message so that application can choose
5594 to use specific private ke if it wants to. If it is not provided,
5595 the normal channel key is used, unless private keys are set.
5596 In this case the first (key that was added first) is used
5597 as the encryption key.
5599 * Implemented the support for channel private key handling.
5600 Implemented the following functions:
5602 silc_client_add_channel_private_key,
5603 silc_client_del_channel_private_keys,
5604 silc_client_del_channel_private_key,
5605 silc_client_list_channel_private_keys and
5606 silc_client_free_channel_private_keys
5608 Affected file lib/silcclient/client_channel.c.
5610 * Added the support for the private keys in the channel message
5611 sending and encryption and in the message reception and
5612 decryption. Affected funtions are
5613 silc_client_send_channel_message and silc_client_channel_message.
5615 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5617 * Added SKE's key verify callback to the client library's
5618 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5620 * Removed the statement that server (or router) must send USERS
5621 command reply when joining to the channel so that the client
5622 knows who are on the channel. Instead, the client list and
5623 client's mode list is now sent in the JOIN command reply to the
5624 client who joined channel. This is better solution.
5626 * Added function silc_server_get_users_on_channel and function
5627 silc_server_save_users_on_channel to the silcd/server.[ch].
5629 * Removed function silc_server_command_send_users from the
5632 * Do not show topic on the client library anymore. The topic is
5633 sent in the command reply notify to the application and the
5634 application must show the topic now.
5636 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5638 * Added client searching by nickname hash into the IDENTIFY and
5639 WHOIS commands in the server as they were clearly missing from
5640 them. Affected file is silcd/command.c.
5642 * Fixed a bug in private message receiving in the client library.
5643 The remote ID was freed and it wasn't supposed, now it is
5646 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5648 * Minor fix to the channel payload; allocate the data area, as it
5649 needs to be of specific length.
5651 * If the key agreement port is zero then the operating
5652 system will define the bound port. Affected files are
5653 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5655 * Added new function silc_channel_payload_decrypt into the file
5656 lib/silccore/silcchannel.[ch].
5658 * Moved the channel message etc, check from silc_packet_decrypt
5659 to applications. The library calls now a generic
5660 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5661 when the packet is either normal or special. This was done to
5662 allow more wide range of checking that was not allowed when
5663 the code was in library. Now applications can do virtually any
5664 checks to the packet and return to the library the decision how
5665 the packet should be processed. Affected files are
5666 lib/silccore/silcpacket.[ch].
5668 Added silc_server_packet_decrypt_check to the server and
5669 silc_client_packet_decrypt_check to the client library.
5671 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5672 to send with specified source and destination information.
5674 * Channel message delivery between routers was broken after the
5675 channel key distribution was fixed earlier. The channel key
5676 was used be to distributed to other routers as well which is not
5677 allowed by the protocol. Now this is fixed and channel keys
5678 really are cell specific and the channel message delivery between
5679 routers comply with the protocol specification.
5681 * Fixed various commands in server to check also the global list
5682 for the channel entry and not just the local list. The affected
5683 file silcd/command.c.
5685 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5687 * Added assert()s to buffer formatting and unformatting routines
5688 to assert (if --enable-debug) when error occurs. Affected
5689 file: lib/silcutil/silcbuffmt.c.
5691 * Changed to auto-reconnect to check whether the remote host is
5692 router and register the re-connect timeout if it is. It used
5693 to check that whether we are normal server, but router must do
5694 auto-reconnect with another router as well. Affected file
5697 * Removed the [<key len>] option from CMODE command as the cipher
5698 name decides the key length, nowadays. See the defined ciphers
5699 from the protocol specification.
5701 * Added [<hmac>] option to the CMODE command to define the HMAC
5702 for the channel. Added SILC_CMODE_HMAC channel mode.
5704 * Added [<hmac>] option for the JOIN command so that user can
5705 select which HMAC is used to compute the MACs of the channel
5708 * Added Hmac field to the Channel Message Payload. The integrity
5709 of plaintext channel messages are now protected by computing
5710 MAC of the message and attaching the MAC to the payload. The
5711 MAC is encrypted. Now, it is clear that this causes some
5712 overhead to the size of the packet but rationale for this is that
5713 now the receiver can verify whether the channel message decrypted
5714 correctly and also when private keys are set for the channel the
5715 receiver can decrypt the packet with several keys and check from
5716 the MAC which key decrypted the message correctly.
5718 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5719 lib/silccrypt/silccipher.[ch].
5721 * Added silc_hash_len to return the digest length into the
5722 lib/silcrypt/silchash.[ch].
5724 * Rewrote parts of Silc Channel Payload interface in the
5725 lib/silccore/silcchannel.[ch]. The encode function now also
5726 encrypts the packet and parse function decrypts it.
5728 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5730 * Fixed a minor formatting bug in the SKE's key material processing.
5731 It actually might have processed the keys wrong way resulting
5734 * Redefined the mandatory HMAC algorithms and added new algorithms.
5735 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5736 and hmac-md5 truncated to 96 bits. The mandatory is now
5737 hmac-sha1-96. Rest are optional (including the one that used
5738 to be mandatory). Rationale for this is that the truncated HMAC
5739 length is sufficient from security point of view and can actually
5740 make the attack against the HMAC harder. Also, the truncated
5741 HMAC causes less overhead to the packets. See the RFC2104 for
5744 * Added new [hmac] configuration section. The SKE used to use
5745 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5746 is of course wrong. The official names that must be proposed in
5747 the SKE are the ones defined in the protocol specification
5748 (hmac-sha1-96 for example). The user can configure any hmac
5749 using any hash function configured in the [hash] section. At
5750 least, the mandatory must be configured.
5752 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5754 * Added HMAC list to the SKE proposal list. It has now both
5755 hash algorithm list and HMAC list. This makes the protocol
5756 incompatible with previous versions. The SKE now seems to work
5757 the way it is supposed to work, for the first time actually.
5759 * Defined plain Hash algorithms to the protocol specification.
5762 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5764 * Implemented support for key agreement packets into the server.
5765 Added functions silc_server_key_agreement and
5766 silc_server_send_key_agreement. Other than these functions,
5767 server has nothing to do with this packet.
5769 * Added support for private message key packets into the server.
5770 Added functions silc_server_private_message_key and
5771 silc_server_send_private_message_key.
5775 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5776 called in the protocol's final callback instead in the END
5777 protocol state. This makes a little more sense and in the same
5778 time in client we can use the same protocol routines for normal
5779 key exchange and to key agreement packet handling as well.
5781 * Added to both client's and server's KE protocol context the
5782 SilcSKEKeyMaterial pointer to save the key material. We will
5783 bring the key material to the protocol's final callback by doing
5784 this. The final callback must free the key material.
5786 * Added SKE's packet_send callback into client's KE protocol
5787 context so that the caller can choose what packet sending function
5788 is used. This way we can use different packet sending when
5789 doing normal SKE when doing key agreement packet handling (in
5790 the key agreement packet handling we do not want to encrypt
5793 * Implemented the responder side of the key agreement routines
5794 in the client. The client can now bind to specified port and
5795 accept incoming key negotiation. The key material is passed
5796 to the application after the protocol is over.
5798 * Implemented the processing of incoming Key Agreement packet
5799 in the client. Added function silc_client_key_agreement to
5802 * Implemented the intiator side of the key agreement routines
5803 in the client. The client can now initiate key agreement with
5804 another remote client. The key material is passed to the
5805 application after the protocol is over.
5807 * Created client_keyagr.c to include all the key agreement
5810 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5811 SILC_TASK_CALLBACK except that it is not static.
5813 * Created client_notify.c and moved the Notify packet handling
5814 from the client.[ch] into that file.
5816 * Created client_prvmsg.c and moved all private message and
5817 private message key routines from the client.[ch] into that file.
5819 * Create client_channel.c and moved all channel message and
5820 channel private key routines from the client.[ch] into that file.
5822 * Changed silc_client_get_client_by_id_resolve to resolve with
5823 WHOIS command instead of IDENTIFY command, in the file
5824 lib/silclient/idlist.c.
5826 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5828 * Implemented the SKE's responder side to the Client library.
5830 * When FAILURE is received to the protocol do not trust it
5831 blindly. Register a timeout to wait whether the remote closes
5832 the connection as it should do it, only after that process the
5833 actual failure. This was changed to both client and server.
5835 * Added client_internal.h to include some of the structures
5836 there instead of client.h in lib/silcclient/.
5838 * Added function silc_task_unregister_by_callback to unregister
5839 timeouts by the callback function.
5841 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5843 * Some "Incomplete WHOIS info" errors has been appearing on the
5844 log files. Took away the entry->userinfo check from WHOIS
5845 reply sending. The entry->userinfo is now " " if client did not
5846 provide one. I thought this was fixed earlier but something
5847 is wrong still. Let's see if the error still appears.
5849 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5851 * Fixed a minor bug in the login when the channel key is
5852 re-generated in the server. It used to generate the key in
5853 wrong order and thus caused problems in the channel traffic.
5855 * Fixed a minor bug in channel key distsribution after
5856 KICK command. The key was not sent to the router even though
5859 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Added silc_ske_process_key_material_data as generic routine
5862 to process any key material as the SILC protocol dictates. The
5863 function is used by the actual SKE library but can be used by
5864 applications as well. This relates to the private message keys
5865 and the channel private keys since they must be processed the
5866 same way the normal SILC session keys. The protocol dictates
5867 this. Affected files: lib/silcske/silcske.[ch].
5869 Added also silc_ske_free_key_material to free the
5870 SilcSKEKeyMaterial structure.
5872 * Defined silc_cipher_set_key function to set the key for
5873 cipher without using the object's method function. The affected
5874 files: lib/silccrypt/silccipher.[ch].
5876 * Implemented silc silc_client_add_private_message_key,
5877 silc_client_add_private_message_key_ske,
5878 silc_client_del_private_message_key,
5879 silc_client_list_private_message_keys and
5880 silc_client_free_private_message_keys functions in the
5883 Added functions silc_client_send_private_message_key to send
5884 the Private Message Key payload and silc_client_private_message_key
5885 to handle incoming Private Message Key payload.
5887 * Added Cipher field to the Private Message Key payload to set
5888 the cipher to be used. If ignored, the default cipher defined
5889 in the SILC protocol (aes-256-cbc) is used.
5891 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5893 * Removed lib/silcclient/ops.h file.
5895 Redefined parts of the SILC Client Library API. Created new
5896 file silcapi.h that deprecates the ops.h file and defines the
5897 published Client Library API. Defined also private message key
5898 API and channel private key API into the file.
5900 This is the file that the application must include from the
5901 SILC Client Library. Other files need not be included by
5902 the application anymore.
5904 * Added new key_agreement client operation callback and also
5905 defined the Key Agreement library API for the application.
5907 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5909 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5910 is used by clients to request key negotiation between another
5911 client in the SILC network. If the negotiation is started it
5912 is performed using the SKE protocol. The result of the
5913 negotiation, the secret key material, can be used for example
5914 as private message key.
5916 Implemented the Key Agreement payload into the files
5917 lib/silccore/silauth.[ch].
5919 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5921 * Redefined ciphers for the SILC protocol. Added some new ciphers
5922 and defined the key lengths for the algorithms. Changed the
5923 code accordingly. The default key length is now 256 bits.
5925 * Fixed SKE key distribution function silc_ske_process_key_material
5926 when the key length is more than 128 bits. The default key
5927 length in SILC is now 256 bits.
5929 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5930 to indicate unsupported algorithm.
5932 * Renamed rijndael.c to aes.c and all functions as well.
5934 * Fixed a long standing channel key setting bug in client library.
5935 Weird that it has never surfaced before.
5937 * Fixed bug in channel deletion. If the entire channel is removed
5938 then it must also delete the references of the channel entry
5939 from the client's channel list as the client's channel entry and
5940 the channel's client entry share same memory.
5942 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5944 * Implemented CONNECT and SHUTDOWN commands in the client.
5946 * Implemented CLOSE command to the client.
5948 * Added the function silc_idlist_find_server_by_name into the
5949 files silcd/idlist.[ch].
5951 Added the function silc_idlist_find_server_by_conn into the
5952 files silcd/idlist.[ch].
5954 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5956 * DIE command was renamed to SHUTDOWN. Updated the both code
5959 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5960 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5962 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5965 * Added function silc_server_create_connection function to create
5966 connection to remote router. My server implementation actually
5967 does not allow router to connect to normal server (it expects
5968 that normal server always initiates the connection to the router)
5969 so the CONNECT command is only good for connecting to another
5972 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5974 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5975 or some other client was kicked from the channel.
5977 Implemented the handling of the notify type to both client
5980 Implemented silc_server_send_notify_kicked to send the KICKED
5981 notify. It is used to send it to the server's primary router.
5983 * Implemented the KICK command into server and client.
5985 * Added `query' argument to the silc_idlist_get_client function
5986 to indicate whether to query the client from server or not if
5989 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5990 to indicate that the client is not channel founder.
5994 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5996 * Removed the rng context from SilcPacketContext structure and
5997 changed that the packet routine uses the Global RNG API.
5999 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6001 * Added support for quit message that client can "leave" on the
6002 channel when it quits the SILC. It is ditributed inside the
6003 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6005 Added silc_server_free_client_data that will take the
6006 signoff message as argument.
6008 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6010 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6012 * Updated parts of the protocol specification to keep it up
6015 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6017 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6018 payloads in one packet.
6020 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6021 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6022 use now the new List flag.
6024 * Also deprecated the following packet types: REPLACE_ID,
6025 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6027 * Added list support for Notify packet in server.
6029 * Added silc_server_send_notify_channel_change to send the
6030 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6031 the silc_server_send_replace_id.
6033 * Added silc_server_send_notify_nick_change to send the
6034 NICK_CHANGE notify type. Deprecates the function
6035 silc_server_send_replace_id.
6037 * Added silc_server_send_notify_join to send the JOIN notify type.
6038 Deprecates the function silc_server_send_new_channel_user.
6040 * Added silc_server_send_notify_leave to send LEAVE notify type.
6041 Deprecates the function silc_server_send_remove_channel_user.
6043 * Added silc_server_send_notify_cmode and
6044 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6045 types. Deprecates the silc_server_send_set_mode function.
6047 * Added SERVER_SIGNOFF notify type to indicate that server has
6048 quit. This means that all clients on the channel from that
6049 server will drop. This can be also used when netsplit happens.
6051 Deprecated REMOVE_ID packet type since it is not needed anymore
6054 Added silc_server_send_notify_server_signoff to send the
6055 SERVER_SIGNOFF notify type. Deprecates the function
6056 silc_server_send_remove_id.
6058 Added also silc_server_send_notify_signoff to send the
6059 SIGNOFF notify type.
6061 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6062 SILC protocol from this day on. Changed the protocol
6063 specification as well.
6065 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6066 notify type. It is used between routers to notify about
6067 topic changes on a channel.
6069 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6072 * Partly updated the protocol specification to comply with the
6073 changes now made. It is still though a bit outdated.
6075 * The JOIN notify type now takes one extra argument <Channel ID>.
6076 The packet used to be destined to the channel but now the
6077 JOIN type may be sent as list thus it is impossible to
6078 destine it to any specific channel. By adding this argument
6079 it is again possible.
6081 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Added CREDITS file. The CHANGES and CREDITS file will appear
6084 in the distribution as well.
6086 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6088 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6089 types in the server's silcd/packet_receive.c.
6091 * Implemented CMODE and CUMODE to work in router environment.
6093 * Fixed minor encoding and decoding buglet from the
6094 lib/silccore/silcmode.c.
6096 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6099 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6101 * Changed all SilcConfigServer* and silc_config_server* to
6102 SilcServerConfig* and silc_server_config*, respectively.
6105 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6107 * Associated the ID (client or server ID) to the Authentication
6108 Payload to avoid any possibility of forging. Updated the
6109 protocol specification and the code accordingly.
6111 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6113 * The RSA key length is now save to the RsaKey context in the
6114 key generation process in lib/silccrypt/rsa.c. The key length
6115 is now used to figure out the maximum size of the block allowed
6116 to be encrypted/signed.
6118 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6119 is equivalent to the silc_mp_mp2bin but does not allocate any
6122 * Changed silc_mp_mp2bin API to take length argument. If it is
6123 non-zero then the buffer is allocated that large. If zero, then
6124 the size is approximated using silc_mp_sizeinbase, which however
6127 * Created Global RNG API which is global RNG that application can
6128 initialize. After initializing, any routine anywhere in the
6129 code (including library) can use RNG without allocating a new
6130 RNG object. This was done to allow this sort of use of the
6131 RNG in code that has no chance to allocate RNG object. All
6132 applications currently allocate this and many routines in the
6133 library use this. Affected file lib/silccrypt/silcrng.[ch].
6135 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6136 it to use the Global RNG API.
6138 * Defined Authentication Payload into protocol specification that
6139 is used during SILC session to authenticate entities. It is
6140 used for example by client to authenticate itself to the server
6141 to obtain server operator privileges.
6143 Implemented this payload into the lib/silccore/silcauth.[ch].
6144 Implemented also routines for public key based authentication
6145 as the new protocol specification dictates.
6147 Moved definitions of different authentication methods from
6148 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6150 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6151 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6152 silc_pkcs_verify_with_hash functions into the file
6153 lib/silccrypt/silcpkcs.[ch].
6155 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6157 * The client entry's userinfo pointer must be always valid.
6158 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6159 will fail since it requires the userinfo. Now, the userinfo
6160 is allocated as "" if actual userinfo does not exist. Actually,
6161 it must exist and it is totally Ok to drop client connections
6162 that does not announce the userinfo. However, we will make
6163 this workaround for now.
6165 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6166 to return the remote port by socket.
6168 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6170 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6171 SILC_SERVER_PENDING_EXEC and added an new macro
6172 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6173 data or when error occurs while processing the pending command.
6175 Added new argument `destructor' into silc_server_command_pending
6176 and to the SilcServerCommandPending object. This destructor is
6177 now called after calling the pending callback or if error occurs
6178 immediately. If error occurs the actual pending callback won't
6179 be called at all - only the destructor. The destructor may be
6180 NULL if destructor is not needed.
6182 All this applies for client library code as well. Similar
6183 changes were made there as well for the pending commands.
6185 In the client, the application must now allocate the
6186 SilcClientCommandContext with the silc_client_command_alloc
6189 * Added reference counter to the SilcServerCommandContext. Added
6190 function silc_server_command_alloc and silc_server_command_dup
6193 Same type of functions added to the client library for the same
6196 * Removed the cmd_ident from IDListData away since it is now
6197 global for all connections. It is the command identifier used
6198 in command sending and with pending commands. The affected file
6201 * Added reference counter to the SilcSocketConnection objecet to
6202 indicate the usage count of the object. The object won't be
6203 freed untill the reference counter hits zero. Currently only
6204 server uses this, and client ignores it. The client must be
6205 set to use this too later. The affected files are
6206 lib/silccore/silcsockconn.[ch]. Added also the function
6207 silc_socket_dup to increase the reference counter.
6209 This was mainly added because it is possible that the socket
6210 is removed underneath of pending command or other async
6211 operation. Now it won't be free'd and proper DISCONNECTING
6212 flags, etc. can be set to avoid sending data to connection that
6213 is not valid anymore.
6215 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6216 the connection. After that it sets SILC_SET_DISCONNECTED.
6217 It is, however, possible that the socket data is not still freed.
6218 The silc_server_packet_process now checks that data is not
6219 read or written to connection that is DISCONNECTED. The socket
6220 get's freed when the reference counter hits zero.
6222 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6224 * Changed the client operation API: channel_message operation's
6225 `sender' is now the client entry of the sender, not the nickname
6226 and the `channel' is the channel entry, not the channel name.
6228 In the private_message operation the `sender' is now also the
6229 client entry of the sender not the nickname.
6231 Affected file is lib/silcclient/ops.h and all applications
6232 using the client operations.
6234 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6236 * Moved the calling of ops->connect() from connect_to_server_final
6237 into receive_new_id functin since that is the point when the
6238 client is actually allowed to send traffic to network. The
6239 affected file is lib/silcclient/client.c.
6241 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6243 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6244 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6245 (if needs broadcasting) instead of broadcasting the packets one
6246 by one which would make a burst in the network traffic.
6248 * Added `broadcast' argument to the functions in silcd/server.[ch]
6249 silc_server_create_new_channel[_with_id] to indicate whether
6250 to send New Channel packet to primary router.
6252 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6254 * Added new function into the silcd/server.[ch] files:
6255 silc_server_create_new_channel_with_id to create new channel with
6256 already existing Channel ID.
6258 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6259 lib/silccore/silcpacket.h. This packet is used t send list of
6260 Set Mode payloads inside one packet. Server uses this to set
6261 the modes for the channels and clients on those channels, that it
6262 announced to the router when it connected to it. The protocol
6263 specification has been updated accordingly.
6265 * The silc_server_new_channel did not handle the packet coming
6266 from normal server as it normally does not send that. However,
6267 when it announces its channels it does send it. Implemented
6268 the support for that.
6270 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6271 into the file lib/silccore/id.h.
6273 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6275 * Fixed memory leaks in the functions silc_idlist_del_client,
6276 silc_idlist_del_channel and silc_idlist_del_server in the file
6277 silcd/idlist.c. All of those leaked like a sieve.
6279 * Fixed some small memory leaks in the client's function
6280 silc_client_notify_by_server.
6282 * Added functions into silcd/server.c: silc_server_announce_clients,
6283 silc_server_announce_channels and silc_server_announce_server.
6284 These functions are used by normal and router server to announce
6285 to its primary router about clients, channels and servers (when
6286 router) that we own. This is done after we've connected to the
6289 These functions effectively implements the following packet types:
6290 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6291 and SILC_PACKET_NEW_ID_LIST.
6293 * Added new functions into the silcd/packet_receive.[ch]:
6294 silc_server_new_id_list, silc_server_new_channel_list and
6295 silc_server_new_channel_user_list to handle the incoming
6296 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6298 * Added support of changing Channel ID in the function
6299 silc_server_replace_id. If the server that announces a channel
6300 to the router already exists in the router (with same name but
6301 with different Channel ID), router is responsible to send
6302 Replace ID packet to the server and force the server to change
6303 the Channel ID to the one router has.
6305 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6306 client that the Channel ID has been changed by the router. The
6307 normal server sends this to the client. Client must start using
6308 the new Channel ID as the channel's ID.
6310 Implemented handling of this new type into lib/silcclient/client.c
6311 into the function silc_client_notify_by_server.
6313 * Added new function silc_idlist_replace_channel_id into the files
6314 silcd/idlist.[ch] to replace the Channel ID.
6316 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6318 * Call silc_server_command_identify_check always when processing
6319 the IDENTIFY command in silcd/command.c
6321 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6323 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6324 send keepalive packets. The packet can be sent by clients,
6325 servers and routers.
6327 Added function silc_socket_set_heartbeat into the file
6328 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6329 If not set, the heartbeat is not performed. The actual
6330 heartbeat is implemented in the low level socket connection
6331 library. However, application is responsible of actually
6334 Added silc_server_send_heartbeat to send the actual heartbeat
6335 packet into silcd/packet_send.[ch]. Server now performs
6336 keepalive with all connections.
6338 * Added silc_task_get_first function into lib/silcutil/silctask.c
6339 to return the timeout task with shortest timeout. There was a bug
6340 in task unregistration that caused problems. TODO has been
6341 updated to include that task system must be rewritten.
6343 * The client library will now resolve the client information when
6344 receiving JOIN notify from server for client that we know but
6345 have incomplete information.
6347 * Rewrote parts of silc_server_remove_from_channels and
6348 silc_server_remove_from_one_channel as they did not remove the
6349 channel in some circumstances even though they should've.
6351 * Encryption problem encountered in server:
6353 The LEAVE command used to send the Channel Key packet to the
6354 router immediately after generating it. However, the code
6355 had earlier sent Remove Channel user packet but not immediately,
6356 ie. it was put to queue. The order of packets in the router
6357 was that Channel Key packet was first and Remove Channel User
6358 packet was second, even though they were encrypted in the
6359 reverse order. For this reason, MAC check failed. Now, this
6360 is fixed by not sending the Channel Key packet immediately but
6361 putting it to queue. However, this is more fundamental problem:
6362 packets that are in queue should actually not be encrypted
6363 because packets that are sent immediately gets encrypted
6364 actually with wrong IV (and thus MAC check fails). So, packets
6365 that are in queue should be encrypted when they are sent to
6366 the wire and not when they put to the queue.
6368 However, the problem is that the current system has not been
6369 designed to work that way. Instead, the packet is encrypted
6370 as soon as possible and left to the queue. The queue is then
6371 just purged into wire. There won't be any fixes for this
6372 any time soon. So, the current semantic for packet sending
6375 o If you send packet to remote host and do not force the send
6376 (the packet will be in queue) then all subsequent packets to the
6377 same remote host must also be put to the queue. Only after the
6378 queue has been purged is it safe again to force the packet
6381 o If you send all packets immediately then it safe to send
6382 any of subsequent packets through the queue, however, after
6383 the first packet is put to queue then any subsequent packets
6384 must also be put to the queue.
6386 Follow these rules and everything works fine.
6388 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6390 * Added new function silc_server_remove_clients_by_server to
6391 remove all client entries from ID list when the server connection
6392 is lost. In this case it is also important to invalidate all
6393 client entires as they hold the invalid server entry. This
6394 fixes fatal bug when server has lost connection and will reconnect
6397 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6399 * Made some sanity checks to silc_server_daemonise like to check
6400 whether the requested user and group actually exists.
6402 * Added sanity check to SKE's silc_ske_responder_finish to check
6403 that the public and private key actually is valid.
6405 * Invalidate the client's nickname when receiving Replace ID
6406 packet and the Client ID is being replaced. This means that the
6407 server will query the nickname if someone needs it (client)
6410 * Sort the ID Cache in client library when the ID Cache data
6411 has changed (needs sorting).
6413 * Do not allow for SILC client to create several connections to
6414 several servers. The client does not support windows right now
6415 and generating multiple connections causes weird behaviour.
6417 Irssi-silc client does support windows and can handle several
6418 connections without problems, see: www.irssi.org and SILC plugin.
6420 * Fixed some places where client was added to the IDList. The
6421 rule of thumb is following (in order to get everything right):
6422 If the client is directly connected local client then the
6423 `connection' argument must be set and `router' argument must be
6424 NULL to silc_idlist_add_client function. If the client is not
6425 directly connected client then the `router' argument must
6426 bet set and the `connection' argument must be NULL to the
6427 silc_idlist_add_client function.
6429 * The funtion silc_server_packet_send_local_channel actually did
6430 not check whether the client was locally connected or not. It
6431 does that now. Fixed a bug related to LEAVE command.
6433 * Fixed Remove Channel User payload parsing bug in server's
6434 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6436 * The server's silc_server_save_channel_key now checks also the
6437 global ID list for the channel as it might not be in the local
6438 list. Fixed a bug related to LEAVE command.
6440 * Is this the end of the [<unknown>] buglet that has been lurking
6441 around for a long time? A little for loop fix in server's
6442 silc_server_command_whois_parse that is used by both IDENTIFY
6443 and WHOIS command. At least, this was a clear bug and a cause
6444 of one type of [<unknown>] buglet.
6446 * WHOIS and IDENTIFY commands call the function
6447 silc_server_command_[whois/identify]_check function even if
6448 we are not router server.
6450 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6452 * Added --with-gmp configuration option. If set the GMP
6453 is always compiled in the SILC source tree. If not set then
6454 it is checked whether the system has the GMP3 installed. If
6455 it has then the GMP won't be compiled (the system's headers
6456 and library is used), if it doesn't have it then the GMP is
6457 compiled in the SILC source tree.
6459 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Changed RSA private exponent generation to what PKCS #1
6462 suggests. We try to find the smallest possible d by doing
6463 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6464 not security fix but optimization.
6466 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6468 * Added new config entry [Identity] to fork the server and run
6469 it as specific user and group. A patch from Bostik.
6471 * Imported Dotconf configuration library into lib/dotconf.
6472 This will be used to create the SILC configuration files later.
6473 It will appear in the distsribution after this commit.
6475 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6477 * A big code auditing weekend happening. Auditing code for
6478 obvious mistakes, bugs and errors. Also, removing any code
6481 Removed files for being obsolete:
6483 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6484 inline in the file lib/silcutil/silcbuffer.h)
6486 o lib/silcutil/silcbufutil.c (the header has inline versions)
6488 Changed code to fix possible error conditions:
6490 o The buffer formatting routines now check that the destination
6491 buffer really has enough space to add the data. This applies for
6492 both buffer formatting and unformatting
6493 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6494 unformatting was changed to accomodate following rules:
6495 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6496 sent to the function while XXX_*STRING will not allocate or copy
6497 the data into the buffer. Instead it sets the pointer from the
6498 buffer into the pointer sent as argument (XXX_*STRING used to
6499 require that the pointer must be allocated already). This change
6500 makes this whole thing a bit more consistent and more optimized
6501 (note that the data returned in the unformatting with XXX_*STRING
6502 must not be freed now). The routines return now -1 on error.
6504 o Tried to find all code that use buffer_format and buffer_unformat
6505 and added return value checking to prevent formatting and
6506 especially unformatting errors and possible subsequent fatal
6509 o Changed ske->x and ske->KEY to mallocated pointers in
6510 lib/silcske/silcske.h. Fixed possible data and memory leak.
6512 o Added return value checking to all *_parse* functions. Fixed
6513 many memory leaks as well.
6515 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6516 so that buffer overflows would not happen. All code now also
6517 checks the return value as it can fail.
6519 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6521 * Added reconnection support to server if the normal server looses
6522 its connection to the router (for example if router is rebooted).
6523 The server performs normal reconnection strategy implemented
6524 to the server. Affected file silcd/server.c.
6526 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6528 * Added new packet type SILC_PACKET_SET_MODE that is used to
6529 distribute the information about changed modes (for clients,
6530 channels and clients channel modes) to all routers in the
6531 network. Updated the protocol specification accordingly.
6533 Added functions into silcd/packet_send.c and
6534 silcd/packet_receive.c: silc_server_send_set_mode,
6535 silc_server_set_mode.
6537 Added new files silcmode.[ch] into lib/silccore that implements
6538 the encoding and decoding of Set Mode Payload. Added new type
6539 SilcSetModePayload. Moved the definitions of different modes
6540 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6542 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6544 * Oops, a little mistake in server's connection authentication
6545 protocol. The protocol is not ended with FAILURE but with
6546 SUCCESS if the authentication is Ok. :) Affected file is
6549 * Implemented NICK_CHANGE notify handling in server in the file
6550 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6551 the local clients on the channel. After the changing nickname
6552 in router environment snhould work and the [<unknown>] nickname
6553 should appear no more.
6555 The silc_server_replace_id function that receives the Replace ID
6556 payload now sends the NICK_CHANGE notify type also in the file
6557 silcd/packet_receive.c
6559 * Changed WHOIS and IDENTIFY command to support the maximum amount
6560 of arguments defined in protocol specs (3328 arguments). This
6561 fixed a bug that caused problems when there were more than three
6564 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6566 * Added extra parameter, command identifier, to the
6567 silc_client_send_command so that explicit command identifier
6570 Changed that ID list routines uses specific command identifier
6571 when sending WHOIS/IDENTIFY requests to the server so that they
6572 can be identified when the reply comes back.
6574 Affected files lib/silcclient/command.[ch],
6575 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6577 * Added `sender' argument to silc_server_packet_send_to_channel
6578 to indicaet the sender who originally sent the packet to us
6579 that we are now re-sending. Ignored if NULL. Affected file
6580 silcd/packet_send.[ch].
6582 * Added some server statistics support in silcd/server_internal.h
6583 SilcServerStatistics structure and around the server code. Also
6584 send some nice statistics information when client is connecting
6587 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6589 * Fixed channel ID decoding in server's JOIN command reply in
6590 silcd/command_reply.c
6592 * Fixed braodcasting of replace ID payload to not to send it if
6593 we are standalone server in silcd/packet_receive.c.
6595 * Fixed all channel message sending routines to not to send
6596 packets to clients that has router set, since they are routed
6597 separately in the same function earlier. Affects file
6598 silcd/packet_send.c and all channel packet sending functions.
6600 * In USERS reply, res_argv[i] are not allocated, the table
6601 is allocated. Thus changed that free the table, not its
6604 * In server's whois_check and identify_check if the client is
6605 locally connected do not send any WHOIS commands - they are not
6608 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6610 * Fixed some minor bugs in client when sending WHOIS command. The
6611 arguments was in wrong order.
6613 * Removed statis function add_to_channel from server in
6614 silcd/command.c that was previously used with the joining but
6617 * Tested USERS command in router environment successfully with two
6618 routers, two servers and two clients.
6620 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6622 * Reorganized the USERS command and command reply in client library
6623 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6624 When the command is given by user we register a pending command
6625 callback that will reprocess the command after the reply has been
6626 received from the server. When reprocessing the packet we then
6627 display the information. Thus, the USERS information is displayed
6628 now in the command callback instead of in the command reply
6629 callback. The processing of the command is same as previously
6630 when server has sent the command reply in the JOINing process.
6632 * Added to USERS command in silcd/command_reply.c to join the client,
6633 we didn't use to know about, to the channel after we've created
6634 a client entry for it. Also, for clienet we did know already still
6635 check whether it is on the channel or not and add it if not.
6637 * Removed silc_server_command_join_notify as the function and its
6640 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6642 * Changed the client's pending command handling to the same as the
6643 server's pending command handling. It is also now possible to
6644 execute command reply functions from other command reply
6645 function as the function callbacks for commands and command
6646 replies are one and same. The pending commands are not static
6647 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6648 in client connection context. Thus, pending commands are server
6649 connection specific as it is convenient.
6651 Changed the function silc_client_command_pending and
6652 silc_client_command_pending_del and added new function
6653 silc_client_command_pending_check. Removed the
6654 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6657 * Added cmd_ident, current command identifier, to the client
6658 connection context in lib/silcclient/client.h to keep track on
6659 command identifiers used in command sending. Client's command reply
6660 function handling now supports the mandatory command identifiers.
6662 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6663 funtions in client to fully support pending command callbacks.
6665 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6666 as one of the arguments to the application in the command reply
6669 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6670 before first releasing SILC but came back. Now it is removed again
6671 and should come back nomore. The FORWARDED flag was used only
6672 by the JOINing procedure by forwarding the command packet to router.
6673 Now, the JOINing procedure has been changed to more generic (due
6674 to various router environment issues) and FORWARDED is not needed
6675 anymore for anything. The protocol specification is yet to be
6678 Now, removed silc_server_packet_forward from server and the flag
6679 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6681 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6683 * Renamed NAMES command to USERS command. The NAMES was named that
6684 due to historical reasons. Now it is renamed. Also, rewrote
6685 parts of the USERS command. The nickname list is not sent anymore
6686 by the server. Only Client ID and mode lists are sent in the USERS
6687 command. Changed this also to the protocol specification.
6689 The client now resolves the names and stuff after it receives
6690 the USERS list from the server when joining to the channel.
6692 * WHOIS and IDENTIFY commands has been changed to support multiple
6693 Client ID's per command. One can now search for multiple users
6694 in the network by sending only one WHOIS or IDENTIFY command.
6695 Changed the code and the protocol specifications.
6697 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6698 uses silc_server_command_whois_parse to parse the request. */
6700 * If normal server, do not parse the WHOIS and IDENTIFY requests
6701 before sending it to the router. Saves some time.
6703 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6705 * Fixed JOIN command on client library. Wrong number of arguments
6706 used to crash the client.
6708 * Added silc_server_channel_has_global function to check whether
6709 channel has global users or not.
6711 * Added silc_server_channel_has_local function to check whether channel
6712 has locally connected clients on the channel.
6714 * The silc_server_remove_from_one_channel now checks whether the
6715 channel has global users or not after given client was removed from
6716 the channel. It also checks whether the channel has local clients
6717 on the channel anymore. If it does not have then the channel entry
6718 is removed as it is not needed anymore.
6720 * The silc_server_notify now checks on JOIN notify whether the joining
6721 client is one of locally connected or global. If it is global then
6722 the channel has now global users on the channel and that is marked
6723 to the channel entry. Also, it now saves the global client to
6724 global list who is joining and JOINs it to the channel. This is
6725 for normal server, that is.
6727 Changed silc_server_send_notify_on_channel,
6728 silc_server_packet_relay_to_channel and
6729 silc_server_packet_send_to_channel check if we are normal server
6730 and client has router set (ie. global client) do not send the
6731 message to that client, as it is already routed to our router.
6733 * Implemented LEAVE notify type handling in silc_server_notify
6736 * Tested LEAVE command in router environment successfully. Tested
6737 with two routers, two servers and two clients.
6741 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6743 * Implemented SIGNOFF notify type handling in silc_server_notify
6746 * silc_server_remove_id now removes the client entry from all channels
6747 it has joined and thusly sends SIGNOFF notify type.
6749 * Rewrote the NAMES list generation in server by removing two excess
6750 loops. The lists are created now inside one loop.
6752 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6754 * silc_server_remove_channel_user checks now also global list
6755 for channel and client.
6757 * silc_server_new_channel_user checks now both local and global
6758 list for channel and client. Fixed a bug in client id decoding.
6759 Used to decode wrong buffer.
6761 * silc_server_channel_message checks now both local and global
6762 list for channel entry.
6764 * Tested channel joining (hence JOIN) in router environment
6765 successfully. Tested with two routers, two servers and two
6768 * Tested channel message sending in router environment successfully.
6770 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6772 * Added silc_server_save_channel_key into server.[ch] to save the
6773 received channel key in Channel Key payload processing. It is
6774 also used in JOIN command reply handling.
6776 Equivalent function silc_client_save_channel_key added into
6777 client.[ch] into client library.
6779 * Changed JOIN command reply to send information whether the channel
6780 was created or not (is existing already) and the channel key
6781 payload. Changed protocol specs accordingly.
6783 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6784 the request was sent by ID and not by nickname. Crashed on
6787 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6789 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6790 now correctly save the received data.
6792 * silc_server_free_sock_user_data now notifies routers in the
6793 network about entities leaving the network.
6795 At the same time implemented functions silc_server_remove_id
6796 and silc_server_send_remove_id to receive and send REMOVE_ID
6797 packets. The packet is used to notify routers in the network
6798 about leaving entities. The ID removed will become invalid in
6801 * Added function silc_idlist_del_server into server. Removes and
6802 free's server entry from ID list.
6804 * silc_server_private_message function now checks, if we are router,
6805 that the destination ID really is valid ID, naturally.
6807 * In router when NEW_ID packet is received (for new client) the
6808 hash of the Client ID is saved in the ID Cache but the
6809 client->nickname is set to NULL, instead of putting the hash
6812 IDENTIFY command now also checks that client->nickname must be
6813 valid. If it is not if will request the data from the server who
6814 owns the client. Added new function
6815 silc_server_command_identify_check.
6817 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6818 to set the command to already allocated Command Payload.
6820 * Tested private message sending in router environment with two
6821 routers, two servers and two clients. Fixed minor bugs and now
6824 * Fixed segfault from client's NAMES command. Used to crash if
6827 * Forwarded packets must not be routed even if it is not destined
6828 to the receiver. Changed server code comply with this.
6830 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6832 * Added `require_reverse_mapping' boolean value to ServerParams
6833 structure. If TRUE (not default) the server will require that
6834 the connecting host has fully qualified domain name.
6836 If the reverse mapping is not required and hostname could not be
6837 found the IP address is used as hostname.
6839 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Implemented version string checking to both client and server.
6842 The check is incomplete currently due to the abnormal version
6843 strings used in development version of SILC.
6845 * Changed all command functions in server to use the new
6848 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6850 * Changed char *data to unsigned char *data in ID Cache system to
6851 support binary data as ID Cache data. Changed code to support
6852 binary data in lib/silccore/idcache.c.
6854 * Renamed silc_server_packet_relay_command_reply to
6855 silc_server_command_reply as it is normal packet receiving
6856 function. Rewrote the function to accept command replys for
6857 servers and not only for clients.
6859 * Mark remote router always as registered server if we are connecting
6860 to it. Otherwise, commands sent by the router to us are ignored.
6862 * All ID List find routines now returns the ID Cache Entry pointer
6863 as well if requested.
6865 * WHOIS command works now in router environment, tested with two
6866 routers, two servers and two clients.
6868 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6869 in router environment (as it is almost equivalent to WHOIS) but
6870 hasn't been tested thoroughly. Added new functions:
6872 silc_server_command_identify_parse
6873 silc_server_command_identify_send_reply
6874 silc_server_command_identify_from_client
6875 silc_server_command_identify_from_server
6877 * Disabled route cache adding because adding two different ID's with
6878 same IP replaces the old cache entry thus giving wrong route.
6879 The entry->router->connection is always the fastest route anyway
6880 so route cache may not be needed. Of course, new routes maybe
6881 established after receiving the ID when the entry->router->connection
6882 might not be anymore the most optimal.
6884 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6886 * Add route cache for received ID for fast routing.
6888 * Added silc_server_packet_route to route received packet on router
6889 that is not destined to us.
6891 * Renamed silc_server_get_route to silc_server_route_get.
6893 * Added id_string and id_string_len fields into SilcServer to
6894 include encoded ServerID for fast comparing without excess
6895 encoding of the ID's.
6897 * Cleaned up WHOIS command on server side. Added following static
6900 silc_server_command_whois_parse
6901 silc_server_command_whois_check
6902 silc_server_command_whois_send_reply
6903 silc_server_command_whois_from_client
6904 silc_server_command_whois_from_server
6906 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6907 arguments in command replies. All command functions should be
6908 updated to use this macro.
6910 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6912 * Minor typo fixes on command reply handling on server.
6914 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6916 * Added silc_server_command_add_to_channel internal routine to add
6917 the client to the channel after router has created the channel and
6918 sent command reply to the server.
6920 * Added generic silc_server_send_command to send any command from
6923 * Use static buffer with ID rendering instead of duplicating data.
6925 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6927 * Fixed a channel user mode bug when joining to a channel server gave
6928 everybody channel founder rights, oops.
6930 * We mark ourselves as the router of the incoming server connection
6931 if we are router ourselves. This way we can check in some packet
6932 sending functions whether it is locally connected server. For
6933 incoming router connections we put NULL.
6935 * For router sending packets locally means now always sending the
6936 packet cell wide; to local clients and local servers. For normal
6937 server sending packet locally means sending it to only local
6940 * Fixed the JOIN command to really work in router environment. If the
6941 channel is created it is always created by the router. Router is
6942 also responsible of making the initial joining to the channel,
6943 sending JOIN notify to the sending server and distributing
6944 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6945 does not exist server doesn't do anything else but forward the
6946 command to the router which performs everything.
6948 * Added silc_server_send_channel_key function to send the Channel Key
6951 * Added silc_server_create_channel_key to create new channel key. The
6952 channel key is now re-generated everytime someone joins or leaves
6953 a channel, as protocol dictates. Note: channel->key_len is the
6956 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6958 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6959 packet_receive.[ch] to separate packet sending and receiving
6960 routines. The server.[ch] now includes everything else including
6961 actual packet processing (writing and reading data) and other
6964 Renamed silc_server_private_message_send_internal to
6965 silc_server_send_private_message. The routine is still though
6966 used only to relay private messages as server does not send
6967 private messages itself.
6969 Renamed silc_server_new_channel to silc_server_create_new_channel
6970 and added new function sicl_server_new_channel that handles the
6971 incoming New Channel packet. Added also new sending function
6972 silc_server_send_new_channel to send New Channel Payload.
6974 * Added new function silc_server_notify to process incoming notify
6975 packet to the server/router. Server may then relay the notify
6976 to clients if needed.
6978 * Added new function silc_server_new_channel_user to process incoming
6979 New Channel User packet. Router will redistribute the packet and
6980 send JOIN notify to its local clients and locally connected servers
6981 if needed. Normal server will send JOIN notify to its local client
6982 on same channel when received this packet. Added also corresponding
6983 sending function silc_server_send_new_channel_user to sent the
6986 * Added boolean route argument to send_notif_to_channel and
6987 packet_send_to_channel functions to attempt to route the packet
6988 if it is TRUE and send only locally if it is FALSE.
6990 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6992 * silc_server_replace_id now broadcasts the received replace ID
6993 packet if it is not broadcast packet already. The router must
6994 broadcast to inform other routers about changed ID.
6996 * Added backpointer to server's router into SilcServer context in
6997 silcd/server_internal.h.
6999 * Fixed silc_server_packet_broadcast to send correct broadcast
7002 * The channel key is now distributed to the local client as soon
7003 as it is received from the router (in router environment) so that
7004 no other packet may be sent for the channel until client has
7007 * silc_server_remove_channel_user now broadcasts the received
7008 Remove Channel User packet if it is not broadcast packet already.
7009 The router must broadcast to inform other routers about removed
7012 * Added users field into SilcPacketContext that is a reference count
7013 of the context. One can increase the reference count by calling
7014 silc_packet_context_dup which is now changed to just increase the
7015 reference count instead of duplicating the data. The reference
7016 count is decresed by calling silc_packet_context_free that will
7017 free the data after the reference count hits zero.
7019 For now on the packet context and everything allocated into it
7020 (including the raw packet from network) must be freed by calling
7021 the new silc_packet_context_free function. Added also new function
7022 silc_packet_context_alloc that must be used now to allocate the
7023 context. This also means that if a routine is asynchronous from
7024 silc_[client/server]_packet_parse_type the packet context must
7025 be duplicated by calling silc_packet_context_dup. Otherwise it
7026 gets free'd after silc_[client/server]_packet_parse_type returns.
7027 Also, one must remember that if packet is duplicated then its
7028 reference count must be decresed by calling the free function as
7029 many times as it was duplicated.
7031 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7032 from both client and server.
7034 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7036 * Made joining to a channel working in router environment.
7038 * Cleaned up JOIN command on server side and create function
7039 silc_server_command_join_channel internal routine to make the
7042 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7044 * Changed silc_command_pending list to SilcDList. Also, added
7045 `ident' field to SilcServerCommandPending structure to identify
7046 the reply and to call correct callback.
7048 Added silc_server_command_pending_check function to replace the
7049 corresnponding macro. The silc_command_pending list is not
7052 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7053 to set identifier to previously allocated Command Payload. It
7054 is used to set identifier for command when resending Command
7057 * Added silc_command_payload_encode_payload to encode Command
7058 Payload buffer from SilcCommandPayload structure.
7060 * Added silc_argument_payload_encode_payload to encode Argument
7061 payload buffer from SilcArgumentPayload structure.
7063 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7065 * Changed WHOIS command to support router connection on server side.
7066 The whois request is always sent to router unless the server is
7067 standalone server. After server has received the reply from the
7068 router will it send the reply to the client.
7070 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7071 broadcast received broadcast packet. The function is used only
7072 by router. The broadcast packet is always sent to the router's
7075 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7076 render given ID to printable string, for log files for example.
7078 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7080 * Made basic router to router connections working. At least they
7081 can now connect to each other but nothing really works the way
7082 they are supposed - yet.
7084 * Added new initiator token to RouterConnection configuration
7085 file in silcd/serverconfig.[ch]. It is used to tell whether we
7086 are the initiator to the remote router or whether we'll expect
7087 the other end to connect.
7089 * Moved registering of listener task to silc_server_init, hence
7090 the server starts listenning as soon as it is run, even if it
7091 does not have connections to other routers. Let's see how well
7094 * Changed default connection retry timeouts for more suitable in
7097 * Removed cipher and such arguments from silc_idlist_add_client
7098 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7099 Added new function silc_idlist_add_data to add the keys and stuff
7102 * Added SilcIDListData structure and added it to SilcClientEntry
7103 and SilcServerEntry as their first field in the structure. This
7104 way we can explicitly cast the ID entries to the SilcIDListData
7105 structure and get common data for the entries. In past, we had
7106 to first check what type of connection it is and then cast it to
7107 correct ID entry type. Now, we can directly cast the opaque
7108 pointer to the SilcIDListData (no matter what ID entry it actually
7109 is) and get the data needed.
7111 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7113 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7114 in some circumstances even if threre were timeout tasks, though not
7115 IO tasks, but tasks anyway. Now fixed.
7117 * Defined SilcServerConnection structure to hold connection specific
7118 stuff about directly connected servers and routers. The definition
7119 is currently in silcd/server_internal.h. I thought about having
7120 a bit more important role fro this struct but for now it is used
7121 only when connecting to other server (or router actually).
7123 * Added connecting retry support in server when connecting to
7124 router(s). The retry feature implement exponential backoff
7125 algorithm. Also, added SilcServerParams structure to hold default
7126 parameters for server. For now, it include these retry settings
7127 and are hard coded. After server is moded to be as Silc Server
7128 Library this structure will be more important.
7130 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7132 * Changed client librarys channel->clients table to SilcList and
7133 changed code accordingly.
7135 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7137 * Changed client's channel table to SilcList and changed code
7138 accordingly. Also changed SilcChannelClientEntry to include back-
7139 pointer to the channel so that client entry can use that structure
7140 as list as well and we have fast cross-reference to the channel.
7141 This change dramatically decreased the complexity of channel
7142 handling with client entry and vice versa (removed one extra
7143 loop when searching for channel entry from many functions).
7145 * Changed server->sim from table to SilcDList and changed code
7148 * NAMES command can now be used from user interface. It will show
7149 the user list on the channel, neatly.
7151 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7152 Code now saves realname of the user if it becomes available.
7154 * Renamed configure.in to configure.in.pre and made ./prepare
7155 script to automatically add correct version string to
7156 configure.in which it creates from configure.in.pre.
7158 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7160 * NAMES command reply now shows users mode with the nickname when
7163 * Moved silc_client_ch[u]mode[_char] functions from
7164 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7165 place sucks, they are utility functions and should be in some
7168 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7170 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7173 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7177 * Added TRQ (efficient deque and list library) into lib/trq. This is
7178 a very good list library that is currently used in the SILC. Defined
7179 SilcList API over the library because I didn't like the API very
7180 much. See lib/trq/silclist.h for the API and examples of how to
7181 use the API. Fixed various places in the code to use the new
7182 SilcList API. The SilcList is meant for lists that has a structure
7183 already defined as a list. It is not suitable to add just some
7184 context to the list (in TRQ, the context is the list actually).
7186 So, I defined SilcDList that can be used for the purpose where
7187 predefined list structure does not exit. This can be used as
7188 such list. Now some context just can be added to the SilcDList.
7189 Currently this list is not used in the SILC just yet, though there
7190 are a lot places where this can replace dynamically allocated
7191 tables and I will fix these places, later, to use SilcDList.
7192 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7193 and use TRQ internally).
7195 Also fixed some annoying warning messages that the original TRQ
7196 code generated. Also minor changes to TRQ's Makefile.in.
7198 * Added support for querying by Client ID to both WHOIS and
7199 IDENTIFY commands into server, as required by the protocol.
7201 * Removed method function pointers from SilcBuffer structure. They
7202 weren't used to anything and just increased the context size for
7203 no good reason. This change also made silc_buffer_alloc and
7204 silc_buffer_free functions inline functions.
7206 * Disabled command flooding detection support until it's fixed so
7207 that it accepts commands in but does not execute them more than once
7210 * Added silc_net_localhost(), to return local hostname, into
7211 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7212 that must be initialized before calling silc_client_init.
7214 * Added new function: silc_server_send_notify_on_channels to send
7215 notify messages to all channels client has joined. It is assured
7216 that the message is sent only once per client.
7218 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7219 lib/silcutil/silcutil.[ch] as silc_format function. The new
7220 function is generic and is used by server as well, not only by
7221 the logging routines.
7223 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7224 the provided version string was not acceptable. Added new function:
7225 silc_ske_check_version into lib/silcske/silcske.h. The function
7226 must be implemented by the application (client or server) and it
7227 does not reside in the SKE library. The function checks the version
7228 string remote end sent.
7230 * Added back pointers (to opaque context and to SilcSocketConnection)
7231 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7233 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7234 duplicate packet context structure.
7236 * Changed `notify' client operation to send same arguments as client
7237 receives from server except for ID's. ID's are mapped to correct
7238 ID entry and that is returned. Also, if channel entry is not sent
7239 by server but the notify is for channel the channel entry is sent
7240 to application (otherwise application doesn't know that it is for
7241 channel (library gets it from packet's Destination ID)).
7243 * Added silc_client_remove_from_channels into client library to
7244 remove a client from all channels it has joined to. Used when
7245 received SIGNOFF notify from server. Added also new function
7246 silc_client_replace_from_channels to replace old ID entry with
7247 new ID entry on all channels. Used when received NICK_CHANGE
7250 * Fixed ID Cache list handling in silc_idlist_get_client in
7251 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7252 to get (or query) client by ID.
7254 * Updated TODO list.
7256 * Added connection authentication status message defined by the
7257 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7258 support for these into the code in client and server side.
7260 * Added generic function silc_client_send_command to send any command
7261 with variable argument list. Application should use this function
7262 to send commands if the command functions provided by the library
7263 does not suite for the application's user interface needs.
7265 * Added new `failure' client operation. Application is notified about
7266 received failure packet if client is executing a protocol. In this
7267 case the protocol's execution has failed.
7269 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7270 is required by the protocol.
7272 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7273 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7276 * Added status flag to SilcSKE object to indicate realtime status
7277 of the SKE protocol.
7279 * Application receives now exactly same command reply arguments as
7280 the library receives from server. However, if ID is received the
7281 corresponding ID entry is returned to the application (eg. Client
7282 ID is mapped to correct SilcClientEntry entry and that is returned).
7283 Changed command_reply client operation due to this change.
7285 * Changed all ID's in commands and in command replys as ID Payloads.
7286 Change affected both client and server side codes.
7288 All ID's sent in SILC network (with execption of ID's in SILC
7289 Packet header) are sent in ID Payload to support variable length
7292 * Server now notifies nick changes and notifies all clients on
7293 the channels about the new nickname (about the new Client ID,
7296 * Implemented CMODE command to change channel modes. Supports all
7297 channel modes defined by the protocol specs except ban and invite
7298 lists. (Also, private channel key mode is supported but support for
7299 setting private channel key in client is missing, thus, this mode
7300 has no effect on client side (except that server requires that the
7301 client uses private channel key and normal channel traffic does not
7304 Also, invite mode works per se, but INVITE command does not work
7305 yet correctly, so you can set channel as invite only channel but
7306 inviting clients to the channel does not work (it is yet to be
7307 thought what's the best way to do it).
7309 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7310 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7311 Implemented CUMODE command to change user's mode on the channel.
7312 Supports all modes defined by the protocol specs.
7314 * Added NAMES command reply to return users modes on the channel.
7316 * Removed unnecessary and slow ciphers from lib/silccrypt.
7318 * Set SO_KEEPALIVE option to connection sockets by default.
7320 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7322 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7323 redefined the Notify Payload into protocol specs.
7325 * Added silc_id_payload_parse_id to get ID directly from raw
7328 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7330 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7331 accept searching by Client ID as well.
7333 * Added support for LEAVE and SIGNOFF notify types in client library.
7335 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7336 to parse ID Payload from raw data.
7338 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7340 * Added flags parameter into silc_ske_assemble_security_properties
7341 function in lib/silcske/silcske.[ch].
7343 * Changed notify client operation to fit better for notify messages
7344 sent by server. The notify payload received from server is now
7345 passed to the application (after parsing it to SilcNotifyPayload).
7346 It is application's responsibility to retrieve the arguments
7347 from the payload and show the message the way it wants. The message
7348 sent by server is implementation specific.
7350 * Changed public keys to comply with the protocol specification.
7351 Old public keys are not supported anymore and are not compatible.
7353 * Removed nickname from Channel Payload as the latest draft removed
7354 it. The client must resolve the nickname from the NAMES command
7355 reply received when it joined the channel.
7357 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7359 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7361 * Fixed some errors in protocol specification drafts.
7363 * Created lib/silccore/silcnotify.c to implement Notify Payload
7364 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7365 generic payloads described by protocol specifications. The file
7366 includes implementations for ID Payload and Argument Payload.
7368 * Changed Command Payload implementation to use the new Argument
7369 Payload. Changed command_xxxx_payload to command_payload_xxxx
7370 to comply with SILC coding conventions.
7372 * Added suppport for Argument Payload handling in Notify Payload
7373 implementation as protocol requires it. Added the new support
7374 into server and client lib as well.
7376 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7378 * Added support for multiple nicknames on same channel. [n] is
7379 added locally to the nickname if there are more than one same
7380 nicknames on the channel.
7382 * Server now sends all nicknames that matched WHOIS request.
7383 Client also shows the list received from server.
7385 * Added TOPIC command to client side. User can now set and show
7386 current topic on channel.
7388 * Added MOTD command to client and server. Also, server sends the
7389 motd when client connects to the server.
7391 * Changed version strings to comply ISO 8601.
7393 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7395 * Fixed protocol error handling in client library. It should now
7396 cope even if the SKE fails for some reason.
7398 * Made new protocol specification drafts for submitting to IETF.
7400 * Implemented TOPIC command to server in silcd/command.c.
7402 * Added two new notify types into lib/silccore/silcnotify.h:
7403 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7404 notify nickname change and topic setting/change on a channel.
7406 * API change of command_reply operation in client library. The
7407 application gets now the status type received from server as well.
7409 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7411 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7413 * Cras fixed and optimized the packet handling even further and
7414 it should work now. Minor change to the prototype of function
7415 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7417 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7419 * Added new function into lib/silcutil/silcschedule.[ch]:
7420 silc_schedule_with_fd to select() a specified fd. The function
7421 returns after timeout expires or data arrives or goes. The
7422 function is used by packet routines to wait that all data is
7423 received from network.
7425 * Fixed data reading from network in lib/silccore/silcpacket.c.
7426 The code now assures that all data is read from the fd and then
7427 continues packet processing. This was a bug fix since the code
7428 used to drop some data in some circumstances.
7430 * Added new function into lib/silcclient/client.[ch]:
7431 silc_client_start_key_exchange to start key exchange after
7432 connection has been established to server. The code internally
7433 now uses this funtion but its main purpose was to provide it
7434 for applications that perform their own connecting. After
7435 application has created a connection it merely calls this
7436 function to start the key exchange between client and server.
7437 The library takes care of everything else after that.
7439 Updated also lib/silcclient/README to explain the usage of
7442 * Do not send to application information that connection has
7443 been established. Application gets notified it by connect
7446 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7448 * Applied cras's patch to add silc_schedule_one function. The
7449 function runs scheduler once and returns.
7451 * Fixed the scheduler after cras messed it up. The timeout
7452 handling works now as it's supposed to work.
7454 * Added into lib/silccore/ silcnotify.h to include notify
7455 message types support. Changed silc_server_send_notify*
7456 functions, in server.[ch], to support those new notify types.
7457 Added the support for the notify types into client library,
7458 as well. Added new notify client operation into ops.h in
7461 * Changed silc_server_packet_send_to_channel to send normal
7462 packets instead of just channel message packets. The function
7463 is now used to send the notify packets to channels. It is not
7464 used to send channel message packets anymore, as server never
7467 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7468 va_arg()s as it seems to require it nowadays. I guess, if SILC
7469 is compiled with older va_arg() the new code should work anyway.
7471 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7473 * Splitted core library. Core library (lib/silccore) includes
7474 now only SILC protocol specific core (and common) components.
7475 Created new utility library (lib/silcutil) that includes more
7476 generic purpose stuff. The stuff for util library was taken
7477 from the old core library. This was minor and easy split.
7479 * Created SILC Client Library (lib/silcclient) that includes
7480 implementation of the SILC client without user interface. This
7481 was major move from silc/ directory. The code has been changed
7482 so that it is transparent towards the user interface. The
7483 silc/ directory includes now the same user interface as before
7484 and it uses the new client library. Read lib/silcclient/README.
7485 Basicly, the client library performs everything else related
7486 to SILC except user interface handling. Also, configuration
7487 files are considered to be part of user interface and library
7488 does not handle them.
7490 This change also changed a lot of structures, function naming etc.
7491 Most important change was that SilcClientWindow object was
7492 renamed to SilcClientConnection in the client library. Created
7493 also new file lib/silcclient/ops.h. Also added new files
7494 silc/local_command.[ch] and silc/client_ops.[ch].
7496 All these changes were made to make it easier for user interface
7497 designers to create what ever user interface for the SILC client
7500 It is also expected that the server will be moved to lib
7501 directory as well and SILC Server Library will be created;
7502 sometimes in the future.
7504 * Removed Local commands from lib/silccore/silccommand.h as
7505 they are application specific and new client library does not
7506 handle any of those anymore.
7508 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7509 old client implementation in silc/.
7511 * Added support for callback functions in SILC_LOG_* macros.
7512 Application can now set its own callbacks that will be called
7513 instead of using the default functions that will always print
7514 the debug messages to stderr (or stdout). Also, debugging can
7515 now be disabled by setting silc_debug to FALSE and re-enabled by
7516 setting it to TRUE. Note, that logging will still work even
7517 if debugging is disabled.
7519 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7520 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7521 silc_log_reset_debug_callbacks.
7523 * To enable debugging in silc client one must give now -d
7524 option on command line.
7526 * Changed silc_schedule_init to automatically allocate task queues
7527 if they are not allocated before calling it.
7529 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7531 * Added GMP 3.1 into math library.
7533 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7535 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7536 a channel in SILC network. The packet is used by servers and
7537 routers to notify other routers that user has left a channel.
7538 This little feature was missing until now. Added the feature
7539 to protocol specification as well.
7541 Added functions: silc_server_send_remove_channel_user and
7542 silc_server_remove_channel_user into server.[ch].
7544 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7545 lib/silccore/silcpacket.h. However, they are not implemented
7548 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7550 * Fixed joining to a channel and sending channel messages
7551 between server and router. The channel message sending should
7552 now work inside a cell.
7554 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7556 * Fixed the private message sending between server and router.
7557 The private message sending should now work inside a cell.
7559 * Added silc_server_replace_id into server.[ch] to replace
7560 existing ID in the SILC network.
7562 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7563 and silc_idlist_replace_server_id into idlist.[ch] in server.
7565 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7567 * Fixed the server to server connections. Server can again now
7568 connect to router. Router to router connections probably does
7571 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7573 * Added dynamic protocol registering support. Now protocols can
7574 registered and unregistered on the fly. Patch by cras.
7576 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7578 * Added lib/contrib directory to hold routines that some platforms
7579 don't have but are needed by SILC.
7581 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7582 into lin/contrib to provide getopt() and getopt_long() for
7583 those who don't have it.
7585 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7587 * Added AWAY command to client. When away message is set and
7588 client receives a private message packet the client automatically
7589 replies to the sender with the away message.
7591 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7592 bug seemed to be the cause of recent problems when compiling
7595 * Added version detection support to SKE protocol specification
7596 and added the new changes to the SKE implementation as well.
7597 There were other minor changes in the SKE protocol as well.
7599 Many changes in lib/silcske/silcske.[ch] and in
7600 lib/silcske/payload.[ch].
7602 * Added ^U functionality, clear input line. Patch from cras.
7604 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7606 * Mainly small bugfixes on core library. Fixed some debugging
7607 logging and buffer overflow in silclog.c.
7609 * Updated config.sub and config.guess on the distribution tree.
7611 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7613 * Added command lagging support in server. Client may execute
7614 commands now only once in two seconds.
7616 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7618 * Optimized packet reception. MAC computation and checking is now
7619 also more optimized. A lot previously duplicated code is now
7620 used as generic by both client and server.
7622 * Fixed key pair generation in clientutil.c
7624 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7626 * Added into lib/silccore/silcbufutil.[ch] new function;
7627 silc_buffer_realloc.
7629 * Moved generic packet sending/encryption functions to
7630 lib/silccore/silcpacket.[ch] from client and server. Some
7631 rewriting of the functions.
7633 * Moved all generic packet reception/decryption functions to
7634 lib/silccore/silcpacket.[ch] from client and server. The
7635 packet processing is now much cleaner in both client and server.
7636 These were major changes in both client and server.
7638 * Created many common functions in server to do packet sending.
7639 Previously code were duplicated a lot, this has been removed
7642 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7644 * Rewrote major parts of the ID cache system. Don't know
7645 whether it is better now or not but at least the API is more
7648 * Major rewrite on ID cache stuff on client because of the ID
7649 cache API changes. Added idlist.c to client.
7651 * Also major rewrite on ID cache stuff on server as well.
7652 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7653 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7654 in hand, instead they are all put into the ID cache system now.
7655 All server_idlist_* routines uses ID cache now instead of
7656 traversing its own lists (those lists does not exist anymore).
7657 SilcIDList though still exists. Also, SilcXXXEntry's are
7660 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7662 * Finally made the SKE implementation compliant to the protocol
7663 specification. All mp integers are now binary encoded as
7664 opposed being HEX encoded.
7666 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7669 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7670 functions: silc_[encode/decode]_pem. Also added function
7671 silc_encode_pem_file to PEM encode with newlines ('\n') for
7674 * SILC public keys are now encoded either PEM or binary. Same
7675 option is for private keys as well. By default private keys
7676 are binary encoded and public keys PEM encoded. Silly HEX
7677 encoding were removed.
7679 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7680 function to create fingerprints.
7682 * Fixed a bug in SHA1; does not change the original data anymore.
7684 * Partly implemented INFO command on client and server side.
7685 Fixed CLEAR command. Changes to SERVER command; show current
7686 server(s) when giving command without arguments. Added
7687 VERSION command to client.
7689 * Added check to server that unregistered connections cannot
7690 execute commands (unless it is specificly allowed).
7692 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7694 * Fixed screen refresh.
7696 * Fixed channel joining bug from client. On some circumstances
7697 client tried to join to a channel it had already joined.
7699 * Added public key verification process into client's protocol.c.
7700 The client now verifies the public key from user and saves
7701 it into ~./silc/serverkeys/ directory.
7703 Added into: clientutil.[ch]: silc_client_verify_server_key.
7705 * Changed SKE protocol's silc_ske_initiator_finish function
7706 to accept callback function that verifies the received public
7707 key. Removed old silc_ske_verify_public_key function.
7709 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7711 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7712 silc_pkcs_private_key[_data]_set.
7714 * Made the password and public authentication more cleaner in
7715 server's protocol.c.
7717 * Removed historic and obsolete protocol `channel_auth' from
7718 both client and server.
7720 * Removed wrong way of sending command status messages from
7721 server to client in server's command.c. The old way violated
7722 protocol specification.
7724 Changes to silccore/silccommand.[ch]: removed
7725 silc_command_encode_status_payload -> not needed anymore,
7726 changed silc_command_encode_payload_va to accept extra
7727 argument on variable argument list. The argument type must
7728 now be provided to the function. Also, added new function:
7729 silc_command_encode_reply_payload_va which is same as
7730 normal command_encode_payload_va except command status type
7731 is provided as extra argument.
7733 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7735 * Added ~./silc directory handling. The directory includes the
7736 public and private keys for the client.
7738 Added silc_client_check_silc_dir, silc_client_create_identifier
7739 and silc_client_load_keys.
7741 * Implemented SILC protocol compliant public key. Added public
7742 and private key saving to and loading from files.
7744 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7745 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7746 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7747 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7748 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7750 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7751 silc_pkcs_load_[public/private]_key.
7753 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7755 * Added silc_server_get_route (route.[ch]) to get connection
7756 data for the fastest route for given ID.
7758 * Implemented INVITE command on client and server. The command
7759 were re-defined in the SILC Protocol Specification and the
7760 implementation now complies with the specification.
7762 * Implemented PING command on client and server.
7764 * Implemented NAMES command on client and server. The server side
7765 supports currently only normal server not router server yet.
7766 Some changes to NAMES definition in SILC protocol specification.
7768 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7770 * Implemented LEAVE command on client and server.
7772 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7773 again. This change was made to the protocol as well. Server
7774 should not violate the protocol specification anymore.
7776 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7778 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7779 was tested. SOCKS4 was not but should work anyway.
