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

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

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

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

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

713 * Added new configuration options and blocks:
714 keepalive_secs, reconnect_count, reconnect_interval,
715 reconnect_interval_max, reconnect_keep_trying and
716 require_reverser_lookup. Added ConnectionParam block, and
717 implemented the connection parameters when connecting as
718 initiator and when accepting connections as responder.

721 whether given configuration value has been given already.
723 Affected files silcd/serverconfig.[c], server.[c].
725 * Splitted the doc/example_silcd.conf.in. Separated the crypto
726 algorithm parts and created new file silcalgs.conf, that
727 is now included from the example_silcd.conf.in.
729 * Optimized the silc_server_connect_to_router_second to take
730 the connection configuration object from the SilcServerConnection
731 object instead of finding it during the connecting phase.
732 Added the configuration object to SilcServerConnection struct.
733 Affected files silcd/server_internal.h, server.c.

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

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

845 * Fixed the channel message payload decryption in the function
846 silc_channel_message_payload_decrypt to not modify the original
847 buffer before it is verified that the message decrypted
848 correctly. Otherwise, next time it is called with correct
849 channel key it won't encrypt since the payload is corrupted.
850 Affected file lib/silccore/silcchannel.c.
852 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

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

895 users list to SilcHashTable. The affected files are
896 lib/silcclient/idlist.[ch].
898 * Fixed a bug in hash table tarversing. While the hash table
899 is traversed with SilcHashTableList the table must not be
900 rehashed. It is now guaranteed that auto rehashable tables
901 are not rehashed while tarversing the list. Also defined that
902 silc_hash_table_rehash must not be called while tarversing
903 the table. Added function silc_hash_table_list_reset that must
904 be called after the tarversing is over. The affected files are
905 lib/silcutil/silchashtable.[ch].
907 * Changed all hash table traversing to call the new
908 silc_hash_table_list_reset in server and in client library.
910 * Added function silc_client_on_channel to return the
911 SilcChannelUser entry if the specified client entry is joined

931 * Create the key in JOIN command of the router did not return
932 the channel key, added check for this. Affected file is
935 * Fixed a channel ID update bug in JOIN command reply. Do
936 not directly upgrade the ID but call the function
937 silc_idlist_replace_channel_id if the ID was changed.
938 Affected file silcd/command_reply.c.
940 * Fixed memory leaks from command calling if it would fail.
941 Affected file silcd/command.c.

968 functions. Affected file silcd/server.c.
970 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
971 which ID was changed. This way the router will send the
972 user list for the channel again, and server won't be in
973 desync in some rare circumstances. Affected file is
974 silcd/packet_receive.c.
976 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1058 method if the IP address based filename is not found.
1060 Fixed the GETKEY command to save the fetched server key
1061 in correct filename.
1063 Print the remote server's hostname now when new key is
1064 received during connection process. Affected file is

1084 * Do not save client history information in SERVER_SIGNOFF.
1085 Fixes the bug in normal server that it does not detect
1086 the client becoming valid after the server becomes back
1087 online. Affected file silcd/server_util.c.
1089 * Added `sock_error' field into the SilcSocketConnection
1090 context. When error occurs during socket operation (read
1091 or write) the error is saved. Added also new function
1092 silc_socket_get_error to return human readable socket error
1093 message. Affected files are lib/silcutil/silcsockconn.[ch],
1094 lib/silcutil/unix/silcunixsockconn.c, and
1095 lib/silcutil/win32/silcwin32sockconn.c.
1097 * The server now prints the socket error message in the
1098 signoff for client. Affected file silcd/server.c.
1100 * Fixed the `created' channel information sending from router
1101 to server in JOIN command. Checks now whether the channel
1102 really was created or not and set it according that.
1104 Fixed the JOIN command to use the client entry's current
1105 ID during the joining procedure instead of the one it sent
1106 in the command (it is checked though), since it can change
1107 between the packet processing and command processing, and
1108 would just case unnecessary pain in the client end. Affected
1109 file silcd/command.c.
1111 * Fixed a channel key payload sending to use correct channel
1112 ID when the server was forced to change the channel's ID by
1113 router. Router sent the key payload with the old Channel ID.
1114 Affected file silcd/packet_receive.c.
1116 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1118 * Call silc_server_save_channel_key only if the key payload
1119 was provided in the JOIN command's command reply. Affected
1120 file silcd/command_reply.c.
1122 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1124 * Fixed silc_mp_sizeinbase to return the value correctly with
1125 MPI. Affected file lib/silcmath/mp_mpi.c.
1127 * Fixed the stop_server signal to correctly stop the scheduler
1128 and gracefully stop the server when SIGTERM or SIGINT signals
1129 are received. Affected file silcd/silcd.c.
1131 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1133 * Simple handling of TERM and HUP signals. Also added some log
1134 flushing call around. Affected file is
1137 * Fixed small bugs in silclog.c. Now buffering output will take
1138 effect after 10 seconds since startup: This will ensure that
1139 no important startup messages are lost. Also output redirection
1140 will preserve original format ([Date] [Type] message).
1141 Affected file is lib/silcutil/silclog.c.
1143 * Added two options to the config file, in the logging section:
1144 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1145 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1147 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1149 * Do not print the warning about log files not being initialized
1150 more than once to avoid excess logging. Affected file is
1151 lib/silcutil/silclog.c.
1153 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1154 the SIM copying in make install in Makefile.am.pre.
1156 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1158 * Rewritten silclog APIs. Globally interesting changes follows:
1159 silc_log_set_files() changed to silc_log_set_file().
1160 silc_log_set_callbacks() changed to silc_log_set_callback().
1161 ROBOdoc documented silclog header file.
1162 SilcLogCb now returns bool to wether inihibit the default
1163 handler or not (to keep the old behaviour return always TRUE).
1164 The new APIs should also fix the problem of the
1165 silcd_error.log file that was written in the current directory.
1168 Log files streams will remain opened after silc_log_set_file()
1169 call, means less CPU usage notably on high traffic servers.
1170 File streams are now full buffered, and flushed to the disk
1171 every 5 minutes, lesses HD activity and CPU usage.
1172 Messages can be redirected, allowing admins to configure
1173 one single logfile for all server messages.
1174 the silc_log_quick global variable to activate fast-logging.
1175 Affected files lib/silcutil/silclog.[ch]
1177 * Changed some code to conform new silclog APIs. Affected
1178 files are doc/example_silcd.conf.in, silcd/server.c
1179 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1182 * Fixed a memory leak that could occur in some situations.
1183 Affected file silcd/serverconfig.c.
1185 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1187 * Added the silc_client_del_client to remove the client from
1188 all channels as well. Affected file lib/silcclient/idlist.c.
1190 * Fixed the client library to correctly remove the client
1191 from all channels when the client entry is being destroyed.
1192 Affected file lib/silcclient/client_notify.c, command.c.
1194 * Added auto-nicking support to the client library. If the
1195 applicatio now sets client->nickname it will be sent to the
1196 server after connecting by the library. This way for example
1197 SILCNICK (or IRCNICK) environment variables will have effect
1198 and always change the nickname automatically to whatever
1199 it is wanted. Affected file lib/silcclient/client.[ch].
1201 * Renamed silc_server_command_bad_chars to the
1202 silc_server_name_bad_chars and moved it to the
1203 silcd/server_util.[ch]. Added also new function
1204 silc_server_name_modify_bad to return nickname that
1205 includes bad characters as new nickname without those
1206 bad characters. This check and modify is now used in
1207 silc_server_new_client when the username is initially set
1208 as nickname, so it must be checked to be valid nickname.
1209 Affected file silcd/packet_receive.c.
1211 * The nickname length is now taken from the packet for real
1212 and not trusted to strlen() since it clearly can return
1213 wrong length for nickname including bad characters. This
1214 also applies to channel names. Affected file silcd/command.c.
1216 * Removed the lib/silcsilm/modules directory. Modules are now
1217 compiled into the lib/silcsim. Fixed the copying of the
1218 modules to follow symbolic links in Makefile.am.pre.
1220 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1222 * Fixed silc_string_regexify list creation. Fixes bugs with
1223 BAN and INVITE commands in server. The affected file is
1224 lib/silcutil/unix/silcunixutil.c.
1226 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1228 * Removed the command destructor entirely from the server's
1229 command and command reply routines. It is not needed, and
1230 its usage was buggy and caused crashes. Affected files are
1231 silcd/command[_reply].[ch].
1233 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1235 * Cancel protocol and NULL sock->protocol if timeout
1236 occurred during protocol. Affected file silcd/server.c.
1238 * Cancel protocol timeouts always before calling the final
1239 callback, to assure that after final callback is called
1240 no other state will be called for the protocol anymore.
1241 Affected file silcd/protocol.c.
1243 * Print error log if incoming connection configuration could
1244 not be found. Affected file silcd/server.c.
1246 * Fixed JOIN command to correctly save the founder mode
1247 to the client on normal SILC server, when the channel
1248 was created by the router. Affected file silcd/command.c.
1250 * Fixed LIST command (hopefully) to send correct reply
1251 packets. Affected file silcd/command.c.
1253 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1255 * The silc_packet_receive_process now returns FALSE if the
1256 read data was invalid packet, and TRUE if it was ok.
1258 The server now checks that if unauthenticated connection
1259 sends data and its processing fails the server will close
1260 the connection since it could be a malicious flooder.
1262 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1264 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1266 * Make sure the warning about error opening a log file is
1267 printed only once and not everytime it fails (produces
1268 too much useless log). Affected file lib/silcutil/silclog.c.
1270 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1272 * Made the silc_server_daemonise() function more readable.
1273 Affected file silcd/server.c.
1275 * Pid file is now optional, the user may comment it out from
1276 the config file. Removed define SILC_SERVER_PID_FILE, we
1277 don't need a default any longer. Affected file
1278 configure.in.pre, lib/Makefile.am.pre.
1280 * Make some use of the pid file. The server now dies at startup
1281 if it detects a valid pid file on his path. The server would
1282 die anyway in this circumstance, because of the bind() failure.
1283 Affected file silcd/silcd.c.
1285 * No longer compiling lib/dotconf.
1287 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1289 * Fixed JOIN command parsing not to crash. Affected file
1290 lib/silcclient/command.c.
1292 * Fied the NICK_CHANGE notify to add the new client entry
1293 even it is resolved. This removes an <[unknown]> nick
1294 thingy bug in the client. Affected file is
1295 lib/silcclient/client_notify.c.
1297 * Do not try to allocate 0 bytes (efence does not like it)
1298 in lib/silccore/silccomand.c when encoding payload.
1300 * Do not take IRCNICK as nickname in Irssi SILC client since
1301 it is not possible to set nickname before hand connecting
1302 the server (TODO has an entry about adding auto-nicking
1305 * Changed the silc_server_command_pending to check whether
1306 there already exists an pending entry with the specified
1307 command, command identifier and pending callback. This is
1308 to fix IDENTIFY and WHOIS related crashes that may register
1309 multiple pending commands with same identifier. Affected
1310 file silcd/command.c.
1312 * Fixed the server to reconnect to the router even if it
1313 was already reconnecting and EOF was received. This to
1314 fix a possibility that the server wouldn't ever try to
1315 auto-reconnect to the router. Affected file silcd/server.c.
1317 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1319 * Fixed the server's password authentication to use the
1320 length of the locally saved password, and not the one
1321 sent in the packet. Affected file silcd/protocol.c.
1323 * Fixed same password authentication problem in the
1324 Authentication Payload handling routines in
1325 lib/silccore/silcauth.c.
1327 * Yet another password authentication problem fixed with
1328 channel password handling in silcd/command.c.
1330 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1332 * If first character of string in silc_parse_userfqdn is '@'
1333 then do not parse it. Affected file is
1334 lib/silcutil/silcutil.c.
1336 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1338 * Fixed minor bug in IDENTIFY command reply sending, which
1339 caused various weird problems during JOIN when it was
1340 resolving names for users. Affected file silcd/command.c.
1342 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1344 * Fixed the IDENTIFY command reply sending to chech better valid
1345 clients. It was possible to send incomplete list of replies.
1346 Affected file silcd/command.c.
1348 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1350 * Added silc_client_command[s]_[un]register functions now to
1351 dynamically register the commands in client library. Removed
1352 the static table of commands. This allows the client library
1353 to call commands without causing the application to know about
1354 what commands library has called.
1356 Removed the INFO command reply kludge to detect when the command
1357 was called by library. Now library use its own command reply
1358 function for INFO command.
1360 Added function silc_client_command_call to call a command.
1361 Application can use it to call command, not access the structure
1364 Now all commands that are sent by the client library (not
1365 explicitly sent by application) use own command reply functions.
1367 Affected files around lib/silcclient/ and in
1368 irssi/src/silc/core/.
1370 * Fixed the WHOIS command reply sending to chech better valid
1371 clients. It was possible to send incomplete list of replies.
1373 Fixed the WHOIS and IDENTIFY to send the request to router
1374 if normal server did not do it and did not find any results.
1376 Affected file silcd/command.c.
1378 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1380 * Moved the internal data from SilcClient context into its
1381 own file, not accesible to application. Affected files
1382 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1383 and other files in client library.
1385 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1387 * Added doc/examples installation target in Makefile.am.pre.
1390 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1393 commands the found client entry will be removed from the
1394 cache, after notifying application about the error. Affected
1395 file lib/silcclient/command_reply.c.
1397 * Changed the /MSG to check for exact nickname user gave, and
1398 not let `nick' match `nick@host' if it is only one found. Now,
1399 user must type the exact nickname (like nick@host2) even if
1400 there are no more than one same nicks found. This is to avoid
1401 a possibility of sending nickname to wrong nickname since
1402 `nick' could match `nick@host'. Affected file is
1403 irssi/src/core/silc-servers.c.
1405 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1407 * Do not print "you are now server operator" or similar when
1408 giving /away command. Affected files are
1409 irssi/src/silc/core/client_ops.c, silc-servers.h.
1411 * Made the silc_server_command_pending_error_check to send
1412 the same command reply payload it received back to the
1413 original sender of the command. This way all arguments
1414 that was received by the server will be received by the
1415 client too. Affected file silcd/command.c.
1417 * Added the silc_idcache_add to return the created cache entry
1418 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1420 * Add global clients to expire if they are not on any channel.
1421 This is because normal server will never know if they signoff
1422 if they are not on any channel. The cache expiry will take
1423 case of these entries. This is done by normal servers only.
1424 The affected files are silcd/command_reply.c,
1425 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1427 * If server receives invalid ID notification for WHOIS or
1428 IDENTIFY and the ID exists in the lists, it is removed.
1429 Affected file silcd/command_reply.c.
1431 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1432 in client then client entry that it matches is searched and
1433 the nickname is printed on the screen for user. Affected
1434 file irssi/src/silc/core/client_ops.c.
1436 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1438 * Use cache entry expire time in the LIST command reply to
1439 purge old entries from the cache after the LIST command
1440 reply has been received. This way we don't have non-existent
1441 entries in the cache for too long. Affected file is
1442 silcd/command_reply.c.
1444 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1446 * If we are normal server, and we've not resolved client info
1447 in WHOIS or IDENTIFY from router, and it is global client,
1448 we'll check whether it is on some channel. If it is not
1449 then we cannot be sure about its validity and will resolve it
1450 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1451 file silcd/command.c.
1453 * Search channel by name (if possible) rather than by ID
1454 in IDENTIFY command's command reply. Affected file is
1455 silcd/command_reply.c.
1457 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1459 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1460 Updated specs and implemented it. Affected file silcd/command.c,
1461 silcd/packet_send.c and silcd/packet_receive.c.
1463 * Implemented the <founder auth> payload handling in the JOIN
1464 command. If provided all conditions for channel joining
1465 except requirement to provide correct passphrase can be
1466 overrided by the channel founder. Updated the protocol specs.
1467 Affected file silcd/command.c.
1469 Added support for founder auth in JOIN command in client
1470 library. Fixed the parsing of the JOIN command now to support
1471 all options as they should be. The affected file is
1472 lib/silcclient/command.c.
1474 * Optimized the WHOIS and IDENTIFY commands to send the request
1475 to router only if it includes nicknames or other names. If
1476 they include only IDs then check the local cache first before
1477 routing. Affected file is silcd/command.c.
1479 * Added channels topic announcements. Affected file is
1480 silcd/packet_receive.c and silcd/server.c.
1482 * Fixed the silc_server_send_notify_topic_set to really destine
1483 the packet to channel. Affected file silcd/packet_send.c.
1485 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1486 library. Affected file lib/silcclient/client_notify.c.
1488 * Added UMODE announcements. Affected file silcd/server.c.
1490 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1492 * Memory leak fixes in:
1494 lib/silcutil/silcsockconn.c
1495 lib/silcske/silcske.c
1496 lib/silcske/groups.c
1498 lib/silccrypt/silcpkcs.c
1499 lib/silccore/silccommand.c
1500 lib/silccore/silcidcache.c
1505 * ROBOdoc documented the lib/silcske/groups.h file and a
1506 bit changed the interface for better.
1508 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1510 * Update the client entry context in the ID cache after
1511 nick change. Affected file lib/silcclient/command.c.
1512 Fixes the CUMODE command when regaining founder privileges,
1513 and a little WHOIS problem.
1515 * Fixed silc_net_gethostbyname to correctly call the
1516 inet_ntop. Affected file lib/silcutil/silcnet.c.
1518 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1520 * Added IPv6 support checking to the configure.in.pre, added
1521 also --enable-ipv6 option to override the check. Affected
1522 file configure.in.pre.
1524 * The silc_thread_create now calls the start function
1525 directly if threads support is not compiled in. Removes
1526 ugly #ifdef's from generic code. Affected files are
1527 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1529 * Added silc_net_gethostby[name/addr]_async to asynchronously
1530 resolve. Affected files are lib/silcutil/silcnet.[ch].
1532 * Added support for rendering IPv6 based server, client and
1533 channel IDs. Affected file lib/silcutil/silcutil.c.
1535 * Added support for creating IPv6 based server IDs. Affected
1536 file is silcd/serverid.c.
1538 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1540 * Added silc_net_gethostby[addr/name] into the
1541 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1542 routines. Added silc_net_is_ip[4/6]. Affected file is
1543 lib/silcutil/unix/silcunixnet.c. All routines that take
1544 address as argument now supports both IPv4 and IPv6 addresses.
1546 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1548 * Fixed LIST command reply sending in server. Affected file
1551 * Server now sends the kicker's client ID in the KICK notify
1552 to the kicked client. Affected file silcd/command.c.
1554 * The client library now parses the kickers client ID and
1555 UI displays it. Affected files lib/silcclient/client_notify.c
1556 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1558 * Made all payload parsing function prototypes consistent.
1559 They all take now const unsigned char * and uint32 pair as
1560 the payload data instead of SilcBuffer. Changes all around
1561 the source tree. Other unsigned char* -> const unsigned char*
1562 changes around the tree as well.
1564 * Optimized SFTP client and server packet sending not to
1565 allocate new buffer for each packet but to recycle the
1566 first allocated buffer. Affected files are
1567 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1569 * Optimized the SFTP client to use SilcList instead of
1570 SilcDList for requests, because it is faster. Affected file
1571 is lib/silcsftp/sftp_client.c.
1573 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1574 into lib/silccore/silcid.[ch].
1576 Renamed silcpayload.[ch] into silcargument.[ch].
1578 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1580 * If client entry is deleted with active key agreement
1581 session, abort the session.
1583 The silc_client_abort_key_agreement now calls the completion
1584 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1586 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1589 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1591 * Don't use __restrict in older GCC's. Affected file is
1592 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1594 * silc_net_localhost now attempts to reverse lookup the
1595 IP/hostname. Affected file lib/silcutil/silcnet.c.
1597 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1598 command. It can be used to gain founder privileges at
1599 the same time when joining the channel.
1601 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1602 kicker's client ID as well. Updated protocol specs.
1604 Defined that the server must send SILC_COMMAND_IDENTIFY
1605 command reply with error status to client who sent
1606 private message with invalid client ID.
1608 Updated the protocol specification.
1610 * Added silc_server_send_command_reply to send any
1611 command reply. Affected file silcd/packet_send.[ch].
1613 * Added silc_id_payload_encode_data to encode ID payload
1614 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1616 * The server now send IDENTIFY command reply with error
1617 status if client ID in private message is invalid. Affected
1618 file silcd/packet_receive.c.
1620 * Save the server key file with server's IP address in
1621 the filename instead of hostname. The affected file is
1622 irssi/src/silc/core/client_ops.c.
1624 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1626 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1629 * Added libtool support for compiling shared objects in
1630 lib/silcsim. Affected file configure.in.pre and
1631 lib/silcsim/Makefile.am. Original patch by cras.
1633 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1635 * Pid file configuration, and server's config file fixes
1636 patch by toma. Updated CREDITS file.
1638 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1640 * Fixed silc_client_channel_message to not try to decrypt
1641 the message twice if it resolved the destination client
1642 information. This could cause of dropping one channel
1643 message. Affected file lib/silcclient/client_channel.c.
1645 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1648 lib/silcclient/client.c. This function is used when the SILC
1649 Client is run under some other scheduler, or event loop or
1650 main loop. On GUI applications, for example this may be
1651 desired to used to run the client under the GUI application's
1652 main loop. Typically the GUI application would register an
1653 idle task that calls this function multiple times in a second
1654 to quickly process the SILC specific data.
1656 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1658 * Fixed silc_server_drop() for dropping the supplementary
1659 groups as well, this could cause a security hole on some
1662 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1664 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1667 * Write PID file after dropping privileges. Added -F option
1668 to run server on foreground. A patch by debolaz.
1669 Affected files silcd/server.c, silcd/silcd.c.
1671 * Fixed MOTD to return the MOTD file server name. Affected
1672 file silcd/command.c.
1674 * Added INFO command reply handling to the Irssi SILC Client.
1675 Affected file irssi/src/silc/core/client_ops.c.
1677 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1679 * Fixed the silc_idcache_list_* routines to really support
1680 the dynamic list. Fixes a crash. Affected file is
1681 lib/silccore/silcidcache.c.
1683 * Fixed the LIST command reply to really call LIST command's
1684 pending callbacks. Affected file silcd/command_reply.c.
1686 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Update conn->local_entry->nickname after giving NICK
1689 command. Affected file lib/silcclient/command.c.
1691 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1693 * Added the [pid] option to the silcd configuration file
1695 Affected files: serverconfig.[ch] and silcd.c
1697 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1699 * Save fingerprint in WHOIS command reply in server.
1700 Affected file silcd/command_reply.c.
1702 * Fixed NICK commands pending callback registration.
1703 Affected file lib/silcclient/command.c.
1705 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1707 * Use ++server->cmd_ident when sending commands in server,
1708 instead of random number. Affected file silcd/command.c.
1710 * Fixed GETKEY command reply to call actually GETKEY pending
1711 command callbacks. Affected file silcd/command_reply.c.
1713 * A bit stricter check for nicknames. Check for same nickname
1714 in NICK command also. Affected file silcd/command.c.
1716 * Do not call INFO command everytime client ID changes, only
1717 during first connecting. Affected file lib/silcclient/client.c.
1719 * Set the new nickname only after successful command reply for
1720 NICK command is returned by server. Affected file
1721 lib/silcclient/command.c.
1723 * Remove nicknames from nicklist during server_signoff notify.
1724 Should fix /NAMES bit more. The affected file is
1725 irssi/src/silc/core/silc-channels.c.
1727 * Added `fingerprint' field to the SilcIDListData in the
1728 silcd/idlist.h to hold the fingerprint of the client's
1731 Send the fingerprint of the client's public key in WHOIS
1734 Affected files silcd/command.c, and silcd/idlist.[ch].
1736 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1737 create fingerprint from given data.
1739 * Show the fingerprint of the client's public key in WHOIS.
1740 Affected files irssi/src/module-formats.[ch] and
1741 irssi/src/silc/core/client_ops.c.
1743 * Format the multiple same nicknames also during JOIN and
1744 NICK_CHANGE notifys. Affected file is
1745 lib/silcclient/client_notify.c.
1747 * Do not print error on screen for invalid private message
1748 payload since it can come if someone is sending private
1749 messages with wrong key. Affected file
1750 lib/silccore/silcprivate.c.
1752 * Fixed multiple concurrent /PING crash. Affected file
1753 lib/silcclient/command.c.
1755 * Changed the wrong ID encoding. All IP addresses must be
1756 in MSB first order in encoded format. They were encoded
1757 wrong and was in LSB format. Affected files are
1758 silcd/serverid.c, lib/silcutil/silcutil.c.
1760 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1762 * Call the `connect' client operation through the scheduler
1763 in case of error. Affected file lib/silcclient/client.c.
1765 * Call the `failure' client operation even if the error
1766 occurred locally during a protocol. Affected file is
1767 lib/silcclient/protocol.c.
1769 * Added support of sending LIST command to router from normal
1770 server. This way normal server can get list of all channels
1771 in the network too. Fixed the channel list sending in the
1772 server too. Affected files are silcd/command.c, and
1773 silcd/command_reply.[ch].
1775 * Added silc_server_update_channels_by_server and
1776 silc_server_remove_channels_by_server. They are used during
1777 disconnection of primary router and in backup router protocol.
1778 Affected file silcd/server_util.[ch], silcd/server.c and
1779 silcd/server_backup.c.
1781 * Fixed channel adding to global list in IDENTIFY command
1782 reply in server. Affected file silcd/command_reply.c.
1784 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1786 * If the incoming packet type is REKEY or REKEY_DONE process
1787 that packet always synchronously. Fixes yet another MAC
1788 failed error on slow (dialup) connections. Affected file
1789 lib/silcclient/client.c and silcd/server.c.
1791 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1793 * Call check_version SKE callback for initiator too. Affected
1794 file lib/silcske/silcske.c.
1796 * Implemented fix for security hole found in the SKE that was
1797 fixed in the specification few days back; the initiator's
1798 public key is now added to the HASH value computation.
1799 Added backwards support for the old way of doing it too, for
1800 old clients and old servers. Affected file is
1801 lib/silcske/silcske.c.
1803 * Enabled mutual authentication by default in SKE. If initiator
1804 is not providing mutual authentication the responder will
1805 force it. This will provide the proof of posession of the
1806 private key for responder. The affected files are
1807 lib/silcclient/protocol.c and silcd/protocol.c.
1809 * Do not cache anymore the server's public key during SKE.
1810 We do mutual authentication so the proof of posession of
1811 private key is done, and if the server is authenticated in
1812 conn auth protocol with public key we must have the public
1813 key already. Affected file silcd/protocol.c.
1815 * Added new global debug variable: silc_debug_hexdump. If
1816 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1817 file lib/silcutil/silclog.[ch].
1819 * Fixed compilation warning due to char * -> const char *.
1820 Affected files lib/silcutil/silcnet.h, and
1821 lib/silccore/silcauth.[ch].
1823 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1825 * Fixed CMODE command when new channel key was created. If
1826 the creation failed the old key was removed. Next time giving
1827 same command would crash the server since the old key was
1828 freed already. Affected file silcd/command.c.
1830 * Fixed the silc_server_announce_get_channels to not crash
1831 on reconnect. Affected file silcd/server.c.
1833 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1835 * Added silc_log_set_debug_string function to set a regex
1836 string to match for debug output. Only the function names,
1837 or filenames matching the given debug string is actually
1838 printed. This way it is possible to filter out those debug
1839 strings that user is not interested in.
1841 Fixed a bug in silc_string_regexify.
1843 Affected files lib/silcutil/silclog.[ch], and
1844 lib/silcutil/unix/silcunixutil.c.
1846 * Changed the -d options in both server and Irssi SILC client
1847 to take the debug string as argument. Affected files
1848 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1850 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1852 * Added silc_hash_babbleprint to create a Bubble Babble
1853 Encoded fingerprint. The encoding is developed by Antti
1854 Huima (draft-huima-babble-01.txt), and it creates human
1855 readable strings out of binary data. Affected file
1856 lib/silccrypt/silchash.[ch].
1858 * Print the babble print now in addition of fingerprint as well
1859 in Irssi SILC client. Affected files are
1860 irssi/src/fe-common/silc/module-formats.[ch],
1861 irssi/src/fe-common/silc/core/client_ops.c.
1863 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1865 * Fixed a security problem found in SKE. The initiator's
1866 public key too is now added to the HASH hash value creation
1867 which is signed by the responder to create the SIGN value.
1868 This will prevent anyone in the middle to lie to the responder
1869 about the initiator's public key. If this is done now, the
1870 man in the middle will get caught. Updated the protocol
1873 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1875 * Better installation directory handling. Configure module
1876 paths and other paths automatically to example_silc* files
1877 in doc/. A patch by toma.
1879 * Fixed compiler warning from MPI library, and from SILC RNG.
1882 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1883 It can be configured with ./configure. A patch by toma.
1885 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1887 * Find correct make to use in prepare-clean. A patch by
1888 toma. Affected file prepare-clean.
1890 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1892 * Added irssi variables use_auto_addr, auto_bind_ip,
1893 auto_bind_port and auto_public_ip.
1895 * Changed the interface for silc_client_send_key_agreement
1896 in lib/silcclient/silcapi.h
1900 irssi/src/silc/core/silc-core.c
1902 lib/silcclient/silcapi.h
1903 irssi/src/silc/core/silc-channels.c
1904 lib/silcclient/client_keyagr.c
1907 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1909 * Added silc_pkcs_public_key_compare to compare two
1910 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1912 * Check that the client who set the founder mode on the
1913 channel is the same client that is giving the founder
1914 mode to itself. It is done by comparing the saved public
1915 key (it is saved even in the authentication is passphrase).
1916 Affected file silcd/command.c.
1918 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1920 * Do not process packet for disconnected socket connection.
1921 Affected file lib/silccore/silcpacket.c.
1923 * Process the DISCONNECT packet through scheduler in the
1924 client library. Affected file lib/silcclient/client.c.
1926 * Fixed the silc_client_packet_parse to not to increase
1927 the packet sequence number if the conn->sock and the
1928 current socket connection is not same. This can happen
1929 for example during key agreement when the conn includes
1930 multiple socket connections (listeners). Affected file
1931 lib/silcclient/client.c.
1933 * The sender of the file transfer request now provides also
1934 the pointer (listener) for the key exchange protocol. If
1935 the listener cannot be created then it sends empty key
1936 agreement and lets the receiver provide the listener.
1938 Added `local_ip' and `local_port' arguments to the
1939 silc_client_file_send. If they are provided they are used,
1940 if not then it will attempt to find local IP address, if
1941 not found or bind fails then the remote client will provide
1944 Affected files are lib/silcclient/client_ftp.c and
1945 lib/silcclient/silcapi.h.
1947 * Extended the FILE SEND command to support defining the
1948 local IP and port for key exchange listener. They are
1949 optional. Affected file irssi/src/silc/core/silc-servers.c.
1951 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1953 * Defined to WHOIS command reply the sending of fingerprint
1954 of the client's public key (if the proof of posession of the
1955 corresponding private key is verified by the server).
1956 Updated to the protocol specification.
1958 * Added support of receiving the client's public key's
1959 fingerprint in command reply in client library. Affected
1960 file is lib/silcclient/command_reply.c, and
1961 lib/silcclient/idlist.[ch].
1963 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1965 * Do not send over 128 chars long nickname to the server
1966 in NICK command. Affected file lib/silcclient/command.c.
1968 * Do not send over 256 chars long channel names to the server
1969 in JOIN command. Affected file lib/silcclient/command.c.
1971 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1973 * Assure that silc_server_close_connection cannot be called
1974 twice for same socket context. Affected file is
1977 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Send error message to application if opening file for
1980 writing during file transfer fails. Affected file is
1981 lib/silcclient/client_ftp.c.
1983 Remove all file transfer sessions for a client that we're
1984 removing from ID cache.
1986 Affected file is lib/silcclient/client_ftp.c.
1988 * Fixed silc_net_addr2bin to return correct address. Affected
1989 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1991 * Fixed file transfer session removing on signoff notify.
1992 Affected file irssi/src/silc/core/silc-servers.c.
1994 * Added the SilcClientFileError to be returned in the monitor
1995 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1996 Affected file lib/silcclient/silcapi.h.
1998 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2000 * Fixed a crash in silc_client_ftp_free_sessions and
2001 silc_client_ftp_session_free_client. Affected file
2002 lib/silcclient/client_ftp.c.
2004 * Added `disabled' field in the SilcChannelEntry in the server
2005 to indicate if the server entry is disabled. Affected file
2006 silcd/idlist.h, silcd/command[_reply].c.
2008 * SILC server adds now /var/run/silcd.pid everytime it is
2009 started. Affected file silcd/silcd.c.
2011 * Added silc_server_packet_send_clients to send a packet to
2012 the provided table of client entries. Affected file
2013 silcd/packet_send.[ch].
2015 * Fixed a crash in client resolving in client_prvmsg.c in
2016 client library. Affected file lib/silcclient/client_prvmsg.c.
2018 * Do not actually remove the client directly from ID cache
2019 during SERVER_SIGNOFF, but invalidate it. This way we
2020 preserve the WHOWAS info for the client. Affected file
2021 silcd/server_util.c.
2023 * Fixed SERVER_SIGNOFF notify handling in the server. The
2024 server is now able to process incoming SERVER_SIGNOFF notify
2025 for a server that it doesn't even know about. It will remove
2026 the clients provided in the notify. Affected file
2027 silcd/packet_receive.c.
2029 * Check for partial packet in data queue after every packet that
2030 was found from the queue. Return and wait for more data if
2031 there is partial data in queue. Affected file is
2032 lib/silccore/silcpacket.c.
2034 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2036 * Added SilcClietFileError enum to indicate error in
2037 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2038 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2039 Affected files lib/silcclient/silcapi.h and
2040 lib/silcclient/client_ftp.c.
2042 * Check that newsize in silc_buffer_realloc is larger than
2043 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2045 * Added better monitor of file transfers. It now monitors
2046 key agreement protocol during the file transfer too. Added
2047 error reporting too. Affected files
2048 irssi/src/silc/core/silc-servers.c,
2049 irssi/src/fe-common/silc/module-formats.[ch].
2051 * Wrote a help file for FILE command.
2053 * Added silc_rng_global_get_byte_fast to get not-so-secure
2054 random data as fast as possible. Random data is read from
2055 /dev/urandom if available and from the SILC RNG if not
2056 available. It is used in padding generation. Affected file
2057 lib/silccrypt/silcrng.[ch].
2059 * All packets in client library are now processed synchronously.
2060 Optimized packet processing a lot. Affected file
2061 lib/silcclient/client.c.
2063 * All server connection packets are processing synchronously
2064 now in server, to optimize packet processing. Affected file
2067 * Include files are installed now only in Toolkit distribution
2068 if make install is given. Affected files: all Makefile.am's.
2070 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2072 * Assure that silc_client_notify_by_server_resolve does not
2073 resolve the client information multiple times. If it cannot
2074 be found by the first it cannot be found at all. Affected
2075 file lib/silcclient/client_notify.c.
2077 * Fixed WHOWAS command reply calling. Affected file
2078 lib/silcclient/command_reply.c.
2080 * Removed all references to silc_idlist_get_client from the
2081 Irssi SILC client since that call is internal call used by
2082 the library. The Irssi SILC client will use now client
2083 retrieval functions found in silcapi.h.
2085 * Fixed a bug in resolving nickname info before sending
2086 private message. It used freed memory. Affected file
2087 irssi/src/silc/core/silc-servers.c.
2089 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2091 * Assure my_channels statistics cannot go negative in server.
2092 Affected files silcd/server.c, silcd/server_util.c.
2094 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2096 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2098 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2100 * Win32 Toolkit changes. Affected files
2101 win32/silc.dsw, win32/libsilc/libsilc.def,
2102 win32/libsilcclient/libsilc.def,

2104 lib/sftp/sftp_fs_memory.c.
2106 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2108 * Added silc_net_localip to return local host's IP address.
2109 Affected file lib/silcutil/silcnet.[ch].
2111 * If key exchange or rekey protocol is active for a connection
2112 parse all packets syncronously since there might be packets
2113 in packet queue that we are not able to process without first
2114 processing packets before them. Affected file silcd/server,
2115 lib/silcclient/client.c.
2117 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2118 whether library should continue processing the packet.
2119 Affected file lib/silccore/silcpacket.h.
2121 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2122 SilcSFTPMonitorData to SFTP server to monitor various

2131 transmission. Affected file lib/silcclient/client_ftp.c,
2132 lib/silccilent/client.[ch].
2134 * Added new local command FILE to the Irssi SILC Client.
2135 It is used to perform the file transfer. It has subcommands
2136 SEND, RECEIVE, SHOW and CLOSE. Affected files
2137 irssi/src/silc/core/client_ops.c,
2138 irssi/src/silc/core/silc-server.[ch].

2142 * Relay the SILC_PACKET_FTP in the server. Affected files
2143 silcd/server.c and silcd/packet_receive.c.
2145 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2147 * Renamed silc_file_read and silc_file_write to functions
2148 silc_file_readfile and silc_file_writefile. Added function
2149 silc_file_open and silc_file_close. Affected files
2150 lib/silcutil/silcutil.[ch].
2152 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2154 * Resolve the client info when received private message or
2155 channel message for a client which nickname we don't know.
2156 Affected files lib/silcclient/client_prvmsg.c and
2157 lib/silcclient/client_channel.c.
2159 * Do not crash in /KEY if client is not connected. Affected
2160 file irssi/src/silc/core/silc-channels.c.
2162 * Added SilcClientStatus field to the SilcClientEntry in the
2163 lib/silcclient/idlist.h.
2165 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2166 is incomplete and is being resolved, it won't be resolved
2169 Make sure also that USERS command reply does not resolve
2170 twice information. Affected file is
2171 lib/silcclient/command_reply.c.
2173 Make sure that silc_client_get_clients_by_list does not
2174 resolve twice same information.
2176 * Check for valid client->id in the silc_server_free_client_data.
2177 Affected file silcd/server.c.
2179 * Fixed /GETKEY nick@server not to crash if the server entry
2180 is not found. Affected file lib/silcclient/command.c.
2182 * Fixed the silc_server_check_cmode_rights to check the
2183 requested modes correctly. Affected file silcd/command.c.
2185 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2187 * Better checks for non-printable chars in nick added.
2188 Affected file silcd/command.c.
2190 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2192 * Call the silc_server_udpate_servers_by_server in the
2193 primary router that comes back online in the backup resuming
2194 protocol. Otherwise it routes packets wrong. Affected file
2195 silcd/server_util.[ch], silcd/server_backup.c.
2197 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2199 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2200 lib/silcutil/silcbuffmt.[ch].
2202 * Redefined the SILC packet header to include the padding
2203 length. Affected file lib/silccore/silcpacket.[ch].
2205 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2206 length for maximum padding up to 128 bytes). Affected
2207 file lib/silccore/silcpacket.h.
2209 * Removed all backwards support for old 0.5.x MAC thingies.
2210 The SILC packet header change makes it impossible to be
2211 backwards compatible.
2213 * Send the ENDING packet with timeout in the backup resuming
2214 protocol. This is to assure that all routers has connected
2215 to the primary router. Affected file silcd/server_backup.c.
2217 * Changed the RNG to take the first IV from random data. It
2218 used to take it from zero actually. Changed the RNG also
2219 to use /dev/urandom during session. /dev/random is used
2220 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2222 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2224 * Changed the SILC packet header to have the first two bytes
2225 (the packet length) encrypted. Affected files aroung the
2226 code tree, lib/silccore/silcpacket.[ch]. Removed the
2227 SilcPacketCheckDecrypt callback. It is not needed anymore
2228 since the silc_packet_receive_process will determine now
2229 whether the packet is normal or special.
2231 * Implemented the unidirectional MAC keys. Affected files
2232 lib/silcske/silcske.c, silcd/protocol.c and
2233 lib/silcclient/protocol.c.
2235 * Implemented the packet sequence number to the MAC computation.
2236 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2237 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2238 lib/silcclient/protocol.c.
2240 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2242 * Allow backup router to announce servers. All servers
2243 announced by backup router are added to the global list
2244 automatically. Update hte server's socket to our primary
2245 router also when backup router announces a server.
2246 Affected file silcd/packet_receive.c.
2248 * Do not update the client->router in the function
2249 silc_server_udpate_clients_by_server if the client is on
2250 global list. We might fail to find any specific server
2251 for locally connected clients and local cell clients. They
2252 should still use the `from' and not `to' as client->router.
2253 This fixes backup router resuming protocol. Affected file
2254 silcd/server_util.c.
2256 * Decrease channel statistics count only if the channel
2257 deletion worked. Affected files are silcd/server.c and
2258 silcd/server_util.c.
2260 * Added silc_server_update_servers_by_server to update origin
2261 of all server entries. Used during backup router protocol.
2262 Affected files silcd/server_util.[ch], silcd/server.c. and
2263 silcd/backup_router.c.
2265 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2266 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2267 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2268 lib/silccrypt/silchmac.c.
2270 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2272 * Assure that router cannot reroute the same channel message
2273 to the sender. Affected file silcd/packet_receive.c.
2275 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2277 * Made better checks that the channel message is not sent
2278 to the router it came from. Affected file is
2279 silcd/packet_send.c. Fixed memory leak too.
2281 * Announce informations for incoming router connection, but
2282 only after checking if it is replaced by backup router.
2283 Affected file silcd/packet_receive.c.
2285 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2287 * Fixed the backup resuming protocol to work in multiple
2288 router environment. Affected file silcd/server_backup.c.
2290 * Route packet only to one router in the function
2291 silc_server_packet_send_to_channel. Affected file is
2292 silcd/packet_send.c.
2294 * Fixed silc_server_send_notify_dest to set the broadcast
2295 flag. Fixed the silc_server_send_notify_topic to actually
2296 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2297 Affected file silcd/packet_send.c.
2299 * Changed the SFTP Filesystem interface. Changed the
2300 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2301 the filesystem operation function. The SilcSFTPFilesystem
2302 is now a context that is allocated by all filesystem allocation
2303 functions and it already includes the operations structure
2304 and filesystem specific context. It is given as argument
2305 now to the silc_sftp_server_start. This made the interface
2306 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2307 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2309 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2311 * Changed the backup router adding and getting interfaces
2312 in the server. The router that will be replaced by the
2313 specified backup router is now sent as argument. Affected
2314 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2317 * Added silc_net_addr2bin_ne to return the binary form of
2318 the IP address in network byte order. Affected files
2319 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2321 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2323 * Check for existing server ID in silc_server_new_server
2324 and in silc_server_connect_to_router_final and remove the
2325 old entry if it exists. Affected file silcd/packet_receive.c,
2328 * Send the channel message always to only one router, either
2329 in upstream or downstream. Affected file is
2330 silcd/packet_send.c.
2332 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2334 * Wrote the definition of the backup resuming protocol to the
2335 protocol specification.
2337 * Removed one redundant channel key generation from normal
2338 server during joining procedure. Removed one redundant
2339 channel key sending from server to router during joining
2340 procedure. Affected file silcd/command.c.
2342 * Made minor bugfixes to the backup router resuming protocol.
2343 Affected file silcd/server_backup.c, server.c.
2345 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2347 * Added --disable-asm configuration option. Affected files
2348 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2351 * Implemented the backup resuming protocol that is used to
2352 resume the primary router position in the cell after the
2353 primary router comes back online. Affected files
2354 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2355 and silcd/server_util.[ch].
2357 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2359 * Sleep two (2) seconds after sending QUIT command to server.
2360 Affected file lib/silcclient/command.c.
2362 * Assure that if outgoing data buffer is pending do not force
2363 send any data. Affected file silcd/packet_send.c.
2365 * Assure that if outgoing data buffer is pending do not force
2366 send any data. Affected file lib/silcclient/client.c.
2368 * Implemented the backup router support when the primary router
2369 goes down. The servers and routers can now use the backup
2370 router as new primary router without loosing connectivity.
2372 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2374 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2375 in the server to indicate disabled entry. All data read
2376 from the connection will be ignored and no data is sent
2377 for entry that is disabled. Affected files are
2378 silcd/idlist.h, silcd/server.c.
2380 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2382 * Created SFTP client and server test programs in the
2383 lib/silcsftp/tests directory.
2385 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2387 * Implemented memory filesystem (virtual filesystem) for
2388 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2391 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2393 * Implemented the SFTP (SSH File Transfer Protocol) to the
2394 lib/silcsftp. It includes SFTP client and SFTP server
2397 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Moved lib/silccore/silcprotocol.[ch] to the
2400 lib/silcutil library.
2402 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2403 take variable argument list pointer as argument. Affected
2404 file lib/silcutil/silcbuffmt.[ch].
2406 * Added silc_buffer_set function that is used to set data
2407 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2408 Affected file lib/silcutil/silcbuffer.h.
2410 * Changed various routines in the core library to use the new
2411 silc_buffer_set instead of allocating new buffer only for
2414 * Added 64-bit value formatting and unformatting support to the
2415 silc_buffer_[un]format routines. Affected file is
2416 lib/silcutil/silcbuffmt.[ch].
2418 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2419 to includes/bitmove.h.
2421 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2423 * Fixed channel user mode saving in client library. Affected
2424 file lib/silcclient/command[_reply].c.
2426 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2428 * Defined the file transfer to the SILC Protocol. Added
2429 new packet type SILC_PACKET_FTP and defined File Transfer
2430 Payload. The mandatory file transfer protocol is SFTP
2431 (SSH File Transfer Protocol). Affected file in addition
2432 of the internet draft is lib/silccore/silcpacket.h.
2434 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2435 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2436 is used as part of backup router protocol when the primary
2437 router of the cell is back online and wishes to resume
2438 the position as primary router.
2440 * Redefined the MAC generation keys in the protocol. The
2441 same key is not used anymore in both direction. Both
2442 direction will now use different keys for sending and
2443 receiving. This fixes a potential security flaw. This
2444 change causes incompatibilities in the protocol.
2446 * Redefined also the MAC computation from the packet.
2447 An packet sequence number is now added to the MAC
2448 computation. This prevents possible replay attacks against
2449 the protocol. This change too causes incompatibilities
2452 Added `sequence' field to the SilcPacketContext to hold
2453 the current sequence number for the packet.
2455 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2457 * Added `created' field to the SilcIDListData in the file
2458 silcd/idlist.h to indicate the time when the entry was
2461 * Added `created' field to the SilcChannelEntry too. Affected
2462 file silcd/idlist.h.
2464 * Added `creation_time' aguments to all the announcement functions
2465 in the server. If it is provided then only the entries that
2466 was created after the provided time frame are actually
2467 announced. Affected file silcd/server.[ch].
2469 * The protocol says that the Channel ID's IP address must be
2470 based on the router's IP address. Added check for this in
2471 the silc_server_new_channel when processing incoming New Channel
2472 Payload. Affected file silcd/packet_receive.c.
2474 * Print out the correct version with --version in SILC client.
2475 Affected file irssi/src/silc/core/silc-core.c.
2477 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2479 * Fixed WHOWAS command to check for completnes of the client
2480 entry always, not just when the command is coming from client.
2481 Affected file silcd/command.c.
2483 * Added new function silc_server_packet_queue_purge to purge the
2484 outgoing data queue to the network. After the function returns
2485 it is guaranteed that the outgoing packet queue is empty.
2486 Affected file silcd/packet_send.[ch].
2488 * Purge the outgoing packet queue in the rekey protocol's final
2489 callback to assure that all rekey packets go to the network
2490 before quitting the protocol. Affected file silcd/server.c.
2492 * Added silc_client_packet_queue_parse as similar function as
2493 in server to the client library. The affected file is
2494 lib/silcclient/client.c.
2496 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2498 * Splitted silcd/server.c and created silcd/server_util.[ch]
2499 for utility functions.
2501 * Added new socket flag SILC_SF_DISABLED to indicate that the
2502 connection is open but nothing can be sent to or received from
2503 the connection. Affected file lib/silcutil/silsockconn.[ch].
2504 The checking for disabled socket is checked in the low level
2505 silc_socket_write and silc_socket_read functions.
2507 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2509 * Allow only nicknames and channel names that fits into the
2510 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2512 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2514 * When processing JOIN command reply in server check that if
2515 the channel exists in our global list we'll move it the local
2516 list. Affected file silcd/command_reply.c.
2518 * Fixed the check whether client is joined on the channel already
2519 in JOIN command. Affected file lib/silcclient/command.c.
2521 * Fixed the JOIN command reply to check whether the channel
2522 already exists. Affected file lib/silcclient/command_reply.c.
2524 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2526 * Added silc_ske_status_string to map the SKE error numbers
2527 to readable strings. The affected files are
2528 lib/silcske/silcske[_status].[ch].
2530 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2532 * Do not show the private channels on the WHOIS channel list
2533 as it is not allowed by the protocol. The affected file is
2536 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2538 * Assure that the packet length digged from the actual packet
2539 is something sensible in the silc_packet_decrypt_rest_special
2540 in lib/silccrypt/silcpacket.c.
2542 * Free and NULL the allocated pointer in silc_hmac_alloc if
2543 the HMAC allocation fails. The affected file is
2544 lib/silccrypt/silchmac.c.
2546 * Print the selected security properties to the log files in
2547 the server. Affected file silcd/protocol.c.
2549 * Add SKE's reference counter even if calling the completion
2550 callback manually. Otherwise it goes negative, although it
2551 does not cause any problems. The affected file is
2552 lib/silcske/silcske.c.
2554 * Remove the client entry with short timeout after giving the
2555 KILL command. Affected file lib/silcclient/command.c.
2557 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2558 case all found clients are already disconnected (WHOWAS would
2559 found them) in the server. Affected file silcd/command.c.
2561 * Update the last_receive (time of last data received) to be
2562 updated only when received private or channel message so that
2563 the idle time showed in WHOIS makes more sense.
2565 * Added boolean field `valid' in to the SilcClientEntry in the
2566 client library to indicate whether the entry is valid or not.
2567 This fixes the nickname change bug on channel when changing
2568 the nickname to be same than the old (like nick to Nick) the
2569 nickname formatter doesn't set the new nick anymore to Nick@host.
2570 Affected file lib/silcclient/idlist.[ch].
2572 * Now actually fixed the nickname changing on disconnection.
2573 Added new function silc_change_nick to the Irssi SILC Client.
2574 Affected file irssi/src/silc/core/client_ops.c,
2575 irssi/src/silc/core/silc-nicklist.[ch].
2577 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2579 * Check that the public key exists in the GETKEY command before
2580 trying to encode it. Affected file silcd/command.c.
2582 * Print some notifications on received public keys with GETKEY
2583 command in the Irssi SILC Client. Affected files are
2584 irssi/src/fe-common/silc/module-formats.[ch],
2585 irssi/src/silc/core/client_ops.c.
2587 * Use IDENTIFY command to resolve the server information in the
2588 GETKEY command instead of INFO command. Affected file
2589 lib/silcclient/command.c.
2591 * All command reply functions in the client library now calls
2592 the pending command reply callbacks even if an error has
2593 occurred. The server has done this a long time and now it was
2594 time to move the client library to this as well. Now all
2595 errors can be delivered back to the pending command reply
2596 callbacks if necessary. Affected files are
2597 lib/silcclient/command[_reply].[ch].
2599 * Change the nickname on disconnection back to the username
2600 because in reconnect the server will enforce it to it anyway.
2601 Affected file irssi/src/silc/core/silc-servers.c.
2603 * Fixed a config file parsing bug in the Irssi SILC client.
2604 Affected file irssi/src/silc/core/clientconfig.c.
2606 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2608 * When printing the channel mode on JOIN, verify that the
2609 channel key and channel's HMAC are valid. Affected file
2610 irssi/src/silc/core/client_ops.c.
2612 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2614 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2615 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2616 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2618 * Removed channel key rekey task deleting from the function
2619 silc_server_save_channel_key. Affected file silcd/server.c.
2620 Added explicit timeout task context instead that is used to
2621 delete the task if we are registering a new task before the
2622 new task has elapsed.
2624 * When channel key rekey occurs the client library now saves
2625 the old channel key for a short period of time (10 seconds) and
2626 is able to use it in case some is still sending channel
2627 messages encrypted with the old key after the rekey. Affected
2628 file lib/silcclient/[idlist.h|client_channel.c].
2630 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2632 * Added check to the silc_server_new_id_real to not accept
2633 new ID if it is the sender's own ID. Affected file is
2634 silcd/packet_receive.c.
2636 * Assure that we do not announce ourself or the one we've
2637 sending our announcements when we're router and are announcing
2638 servers to our primary router. Affected file silcd/server.c.
2640 * Fixed silc_server_command_identify_check_client to assemble
2641 correct WHOIS packet. It send corrupted WHOIS packet and
2642 caused problem with router to router connections. Affected
2643 file silcd/command.c.
2645 Fixed also silc_server_command_whois_check the same way
2646 as for the IDENTIFY command.
2648 * Added new SilcIDListStatus to the server in the SilcIDListData
2649 structure. The status now includes the current status of
2650 the entry (like registered, resolved etc.). Affected file
2651 silcd/idlist.[ch]. Defined a bunch of different status types
2652 as well. This replaced the old boolean registered field as well.
2654 Added resolve_cmd_ident field to the SilcClientEntry structure
2655 too so that if the entry is for example being resolved so
2656 another command may attach to the same pending command reply
2657 without requiring to resolve the same entry again. This concept
2658 should optimize the WHOIS and the IDENTIFY resolving under
2659 heavy load by taking away unnecessary resolving for entries
2660 that are being resolved already.
2662 Added support for adding multiple pending commands for one
2663 command idenfier. Affected file silcd/command[_reply].[ch].
2665 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2666 before deleting the data. Otherwise the hash table will have
2667 freed data in comparison functions. Affected file is
2668 silcd/command_reply.c.
2670 * Fixed silc_idlist_replace_client_id to add the new entry to
2671 the cache with NULL nickname. Otherwise there will be invalid
2672 memory as the nickname after the nickname is freed. Affected
2673 file silcd/packet_receive.c.
2675 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2676 saved into wrong slots because the previous number of entries
2677 was not taken into account. Affected file silcd/idlist.c.
2678 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2680 * If we are router and we receive JOIN notify to a channel that
2681 does not have any users then notified client is marked as the
2682 channel founder, as it is it. The affected file is
2683 silcd/packet_receive.c
2685 * Added to the extended hash table API's table_del_*ext functions
2686 the destructor as argument too, so that the caller can decide
2687 which destructor to use or whether to use destructor at all.
2688 Affected file lib/silcutil/silchashtable.[ch].
2690 * Fixed ID Cache purging. It actually deleted the entries from
2691 the hash table after the data was freed. The hash table ended
2692 up comparing freed memory. The affected file is
2693 lib/silccore/silcidcache.c.
2695 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2697 * Fixed Irssi SILC client's KILL command's HELP syntax.
2699 * The USERS command now resolves the detailed user information
2700 if the userinfo field is missing. Affected file is
2701 lib/silcclient/command_reply.c.
2703 * Do not print error in silc_file_read if the read file does
2704 not exist. Just silently return NULL. Affected file is
2705 lib/silcutil/silcutil.c.
2707 * Fixed the silc_log_output to not wine about NULL filename
2708 and to not create some bogus " " filename. Affected file is
2709 lib/silcutil/silclog.c.
2711 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2713 * Fixed various printing bugs on the user interface in the
2714 Irssi SILC Client. Minor changes that were forgotten from
2717 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2719 * Fixed the configure.in.pre and the compilation and distribution
2720 environment to support the new autoconf 2.52. That version is
2721 now required to compile the CVS trunk.
2723 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2725 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2726 to generally parse user@fqdn format strings. Affected file
2727 lib/silcutil/silcutil.c.
2729 * Added nickname_format and nickname_force_format fields to the
2730 SilcClientParams structure. The first one defines the format
2731 for the nicknames that the library will enforce if the receives
2732 multiple same nicknames. The second one is boolean value and
2733 can be used to force the library to always enforce the format
2734 to the nicknames regardles whether there are multiple nicknames
2735 or not. This configurable formatting was employed to flexibly
2736 support accessing multiple nicknames from the user interface.
2737 The userinterface can now set the nicknames to what ever format
2738 they prefer. Affected file lib/silcclient/silcapi.h.
2740 Added function silc_client_nickname_format to the file
2741 lib/silcclient/idlist.c. It performs the nickname formatting.
2743 Added new field `hostname´ to the SilcClientEntry context.
2744 It holds the hostname of the client. Affected file is
2745 lib/silcclient/idlist.h.
2747 * Irssi SILC Client sets the nicknames in nick@hostn format.
2748 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2749 irssi/src/silc/core/silc-core.c.
2751 The WHOIS printing now also shows both the real nickname and
2752 the formatted nickname so that user knows how to access the
2753 user if there are multiple same nicknames cached. Affected
2754 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2755 printing formatting too to take the hostname now as a separate
2756 argument. The Affected file is
2757 irssi/src/fe-common/silc/modules-formats.[ch].
2759 * Changed the silc_client_get_clients_local to accept the formatted
2760 nickname as argument. It accepts the real nickname too but the
2761 formatted nickname can be used to find the true entry from
2762 multiple entries. Affected file lib/silcclient/silcapi.h and
2763 lib/silcclient/idlist.c.
2765 * Added nickname_format_parse field to the SilcClientParams.
2766 It is a callback function provided by the application to parse
2767 the nickname out of the formatted nickname string. The library
2768 calls it to get the nickname from the formatted string. Since
2769 the application generally knows better the format of the nickname
2770 string it parses it instead of the library, even though library
2771 encodes the formatted string. If the callback function is not
2772 provided then the library will use the string as is. The
2773 affected file is lib/silcclient/silcapi.h.
2775 * All the nickname strings passed to the client library in
2776 commands are now expected to be formatted nickname strings.
2777 If the command does not support the formatted nickname string
2778 it will assume that the sent string is the actual nickname.
2779 Affected file lib/silcclient/command.c.
2781 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2783 * Added public key authentication support to OPER and SILCOPER
2784 commands in the client library. Affected file is
2785 lib/silcclient/command.c.
2787 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2789 * Changed the get_auth_methdod client operation to be asynchronous.
2790 It can be async if the application resolves the authentication
2791 method from the server during the negotiation. Added new
2792 SilcGetAuthMeth completion callback that the application will
2793 call after resolving the authentication method.
2795 Added function silc_client_request_authentication_method that
2796 the application can use to resolve the authentication method
2797 from the server. Added also SilcConnectionAuthRequest callback
2798 that the library will call after the server has replied. The
2799 application can call this function if it does not know the
2800 current authentication method.
2802 Affected files are lib/silcclient/client.c and
2803 lib/silcclient/silcapi.h.
2805 * The Irssi SILC client now automatically resolves the authentication
2806 method incase any configuration information is not present (and
2807 currently there never is). The affected file is
2808 irssi/src/silc/core/client_ops.c.
2810 * Fixed public key authentication from the client library.
2811 Affected file lib/silcclient/protocol.c. Changed also the
2812 protocol specification about the public key authentication in
2813 the connection authentication protocol. The actual data to be
2814 signed is now computed with a hash function before signing.
2816 * Fixed the public key authentication from the server as well.
2817 Affected file silcd/protocol.c.
2819 * Removed the mlock()'s from the memory allocation routines.
2820 Affected file lib/silcutil/silcmemory.c. The ./configure does
2821 not check anymore for the mlock(). Affected file is
2824 * Fixed USERS command in server to allow the execution of the
2825 command for private and secret channels if the client sending
2826 the command is on the channel. Affected file silcd/command.c.
2828 * Fixed silc_client_get_clients_local to return the clients
2829 count correctly. It could return wrong value. Affected file
2830 lib/silcclient/idlist.c.
2832 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2834 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2835 types. The assembler optimizations seemed not to like 64-bit
2836 data types. The assmebler optimizations thus are now enabled
2837 also for BSD systems as opposed to only enable them for Linux.
2839 * Do not check for threads at all on BSD systems. Affected
2840 file configure.in.pre.
2842 * Removed -n and -h options from the Irssi SILC Client since
2843 they are not used in silc.
2845 * Fixed the prime generation to assure that the first digit
2846 of the generated random number is not zero since our conversion
2847 routines does not like number strings that starts with zero
2848 digit. If zero digit is seen the random number is regenerated.
2849 This caused some corrupted RSA keys when the zero first digit
2850 was met. Affected file lib/silcmath/silcprimegen.c.
2852 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2854 * Fixed WIN32 configuration in the ./configure script.
2855 Fixed to include xti.h on environments that has it.
2856 Patches by Carsten Ilchmann and andrew.
2858 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2860 * Changed the silc_id_create_client_id to be collision
2861 resistant. It is now assured that there cannot be created
2862 two same client ID's. I suspect that some weird bugs in
2863 the server were actually caused by duplicate Client IDs.
2864 Affected file silcd/serverid.[ch]. A router receiving
2865 new ID now also assures and informs the sending server
2866 if the ID caused collision.
2868 * Changed the silc_id_create_channel_id to also assure that
2869 there are no collisions.
2871 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2873 * Statement about ignoring the Mutual Authentication flag when
2874 performing rekey with PFS was a bit misleading. It is ignored
2875 if it was set in the initial negotiation, it cannot be even
2876 set in the rekey. Fixed in the ke-auth draft. Started the
2877 new versions of the protocol drafts in the doc/.
2879 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2881 * Fixed a bug in silc_client_command_identify_save when saving
2882 new channel information. The channel name was no duplicated
2883 and caused crash on exit. Affected file is
2884 lib/silcclient/command_reply.c.
2886 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2888 * Fixed the getkey command handling in the server. Send just
2889 empty OK reply to the sender if the key could not be fetched
2890 (but everything else was ok, like the key just was not available).
2891 Changed the public key parameter to optional in the protocol
2892 specs so that empty OK reply can be sent. Affected file
2895 Added a message to Irssi SILC client to tell to user if the
2896 server did not return a public key.
2898 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2900 * Fixed a channel key regeneration bug. It registered new
2901 timeout tasks exponentially until all system resources were
2902 used. Affected file silcd/server.c.
2904 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2906 * Added the SILC Document generator to the scripts/silcdoc.
2907 It can be used to generate the Toolkit Reference Manual out
2908 of the source tree. Internally it will also use the RoboDoc
2909 generator now imported in util/robodoc.
2911 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2913 * Added couple of return's in rekey protocol if error orccurred
2914 during the protocol. The execution must be terminated.
2915 Affected file silcd/protocol.c. Also, terminate the protocol
2916 always with timeout.
2918 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2920 * The client's Client ID was created initally from the wrong
2921 nickname (it could have been in format nick@host) in the
2922 silc_server_new_client. Affected file silcd/packet_receive.c
2924 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2926 * Added some SILC_LOG_ERROR's to various error conditions
2927 if client could not be added to ID cache. Affected files
2928 silcd/packet_receive.c and silcd/server.c.
2930 * When client's sock->user_data is freed, NULL also the
2931 client->router and client->connection pointers. Added check
2932 for these pointers being NULL to various places around the
2933 code. Affected file silcd/server.c.
2935 * Added client->data.registered == TRUE checks to various
2936 places around the code to assure that unregistered client's
2937 are not handled when it is not allowed. Affected file
2940 * Added `bool registered' fields to all
2941 silc_idlist_[server|client]_get_* routines to indicate whether
2942 the fetched client needs to be registered or not. Affected
2943 file silcd/idlist.[ch].
2945 * Add your own entry as registered to the ID cache in the
2946 server. Affected file server.c.
2948 * Fixed a bug in silc_server_new_server. The SilcServer was
2949 set as the new server's context instead of SilcServerEntry.
2950 This naturally caused some weird bugs.
2952 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2954 * Do not delete the channel rekey task when adding it
2955 for in silc_server_create_channel_key.
2957 * Changed the silc_server_create_channel_key to return
2958 TRUE or FALSE to indicate the success of the channel key
2961 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2963 * Fixed MSVC++ project files and added missing files to
2964 Makefiles under win32/.
2966 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2968 * Do not add TCP_NODELAY flag if the operating system
2969 does not have it defined. Affected files are
2970 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2972 * Fixed buffer overflow from Irssi SILC Client. Affected
2973 file irssi/src/fe-common/core/themes.c.
2975 * Fixed double free in client library in the file
2976 lib/silcclient/client.c when disconnecting from server.
2978 * Applied double free patch from cras to Irssi SILC client.
2979 Affected files irssi/src/core/[modules/expandos].c
2981 * Fixed the disconnection handling to Irssi SILC Client.
2982 The application must call silc_client_close_connection
2983 in ops->connect client operation in case of failure of
2984 the connection. Affected file is
2985 irssi/src/silc/core/client_ops.c.
2987 * Do not set sock->protocol to NULL in the function
2988 silc_client_close_connection after executing the protocol's
2989 final callback since the sock might not be valid anymore.
2990 Affected file lib/silcclient/client.c.
2992 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2994 * Do not enable SILC_THREADS if the linking with libpthread
2995 did not happen. Affected file configure.in.pre.
2997 * Added notion to protocol specification that server must
2998 verify the sent authentication payload with CMODE when
2999 setting the channel founder key. Implemented it to the
3000 server. Affected file silcd/command.c.
3002 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3004 * Added _EXTRA_DIST SILC distribution variable to the
3005 distributions file. It is used to conditionally add extra
3006 files or directories to the specific distribution. Affected
3007 files ./prepare, Makefile.am.pre and distributions.
3009 Removed the `_' from the start of the distribution names.
3012 * Added README.WIN32 for instructions to compile the Toolkit
3015 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * Fixed a double free in disconnection in the server. Affected
3018 file is silcd/server.c.
3020 * Fixed the lib/silcske/groups.c to work now also with GMP
3021 MP library. The string conversion did not work when using
3022 specific base and the base is indicated in the string as well.
3024 * Created win32/ directory which now includes MSVC++ specific
3025 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3026 It will appear only in the toolkit distribution
3028 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3030 * Changed the key material distribution function in case when
3031 the hash output is too short. The data is now concatenated
3032 a bit differently than it used to. Made the change to the
3033 SKE protocol specification.
3035 * Added better GMP detection to configure.in.pre. A patch
3038 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3040 * Fixed a minor bug in SKE that might cause some problem on
3041 some platforms. Affected file lib/silcske/silcske.c.
3043 * Added the cookie checking for initiator in the SKE. It checks
3044 that the responder returns the sent cookie unmodified. The
3045 affected file is lib/silcske/silcske.c. Added new SKE
3046 error type INVALID_COOKIE that can be sent during the
3047 negotiation. Fixed some memory leaks as well.
3049 * Added the "invalid cookie" error message to Irssi SILC client's
3052 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3054 * Added `task_max' field to the SilcClientParams to indicate
3055 the maximum tasks the scheduler can handle. If set to zero,
3056 default values are used. Affected file lib/silcclient/silcapi.h.
3058 * Fixed memory leaks in silc_client_close_connection. Affected
3059 file lib/silcclient/client.c.
3061 * Added silc_client_del_client_entry to client library to free
3062 all memory of given client entry. Affected file is
3063 lib/silcclient/idlist.[ch].
3065 * Added new functions silc_client_del_channel and
3066 silc_client_del_server to delete channel and server entries.
3067 Affected file lib/silcclient/[silcapi.h/idlist.c].
3069 * Removed silc_client_del_client_by_id from silcapi.h.
3071 * Fixed the INFO command to return the server's own info
3072 correctly when querying by Server ID. Affected file is
3075 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3077 * Removed the non-blocking settings in WIN32 code in the
3078 silc_sock_[read/write] and added SleepEx instead. Affected
3079 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3080 of input data is now checked with FIONREAD and ioctlsocket.
3082 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3084 * Call silc_schedule_task_del_by_context in the
3085 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3086 Affected file lib/silccore/silcprotocol.c.
3088 * Call silc_protocol_cancel for active protocols in the
3089 silc_server_close_connection if the funtion
3090 silc_server_free_sock_user_data has not been called.
3091 Affected file silcd/server.c.
3093 * Generic tasks cannot be deleted using the del_by_fd
3094 task deleting function since generic tasks does not match
3095 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3097 * Added a notion to SILCOPER help file that the SILCOPER works
3098 only on router server, not on normal server.
3100 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3102 * Added for WIN32 support for the new scheduler as well.
3103 Affected file lib/silcutil/win32/silcwin32schedule.c.
3105 * Fixed the SHA1 implementation to work on various platforms.
3107 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3109 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3110 API. It is part of the scheduler now. Everything else is
3111 as previously but some functions has changed their names.
3112 Checkout the lib/silcutil/silcschedule.h for the interface.
3113 Updated all applications to use the new interface. Affected
3114 files are lib/silcutil/silcschedule.[ch].
3116 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3118 * Found a bug in the SKE implementation. The HASH value,
3119 specified by the protocol, was not computed correctly. The
3120 public key of the responder was not added to the computation
3121 even though it is mandatory. Affected file lib/silcske/silcske.c.
3122 This unfortunately causes incompatibilities with older
3123 clients and servers.
3125 * Added WIN32 specific network init and uninit functions:
3126 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3127 the Winsock2. Affected file lib/silcutil/silcnet.h and
3128 lib/silcutil/win32/silcwin32net.c.
3130 * Set the socket always to nonblocking mode on WIN32 after
3131 reading data or writing data. Affected file is
3132 lib/silcutil/win32/silcwin32sockconn.c.
3134 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3136 * Fixed various compilation problems under WIN32. Affected
3137 files lib/silcutil/win32/silcwin32thread.c and
3138 lib/silcutil/win32/silcwin32schedule.c.
3140 * Removed all _internal.h #includes from public header
3141 files. Internal headers must never be included from
3144 Removed also the lib/silcske/payload_internal.h file.
3146 * All include files that may be needed (public and some others
3147 included by the public headers) by application developers are
3148 now copied to the ./includes directory. It does not copy any
3149 internal headers. Affected file Makefile.defines.pre and all
3150 Makefile.am's under lib/ and subdirs.
3152 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3154 * Do not change the ~/.silc directory's permissions automatically.
3155 Affected file irssi/src/silc/core/clientutil.c.
3157 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3159 * Do not cancel the protocol in silc_server_close_connection
3160 it might cause recursion. Now cancelled in the function
3161 silc_server_free_sock_user_data. Affected file silcd/server.c.
3163 * Fixed the silc_server_remove_clients_by_server to regenerate
3164 the channel keys correctly finally. Added also new function
3165 silc_server_remove_clients_channels to actually do it.
3166 Affected file silcd/server.c.
3168 * Fixed the silc_server_new_channel to not crash by giving
3169 wrong router to the new channel. Affected file is
3170 silcd/packet_receive.c.
3172 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3174 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3175 which is given as argument to the silc_client_alloc now.
3176 It can be used to configure the client and set various parameters
3177 that affect the function of the client.
3179 * The USERS command in server did not check whether the channel
3180 is private or secret. Affected file silcd/command.c.
3182 * Added new argument to the USERS command in protocol specification.
3183 The USERS command now can take the channel name as argument
3184 as well. Added support for this in client and server and
3185 updated the protocol specs.
3187 * Completed the GETKEY command in client. It can be now used
3188 to fetch also servers public key not only some clients.
3189 Affected files lib/silcclient/command[_reply].c.
3191 * Added silc_client_get_server to return server entry by the
3192 server name. Affected files lib/silcclient/silcapi.h and
3195 * Redefined the IDENTIFY command in protocol specification to be
3196 more generic. It now can be used to query information about
3197 any entity in the SILC Network, including clients, servers and
3198 channels. The query may be based either the entity's name
3199 or the ID. Added support for this in both client and server.
3201 Affected files silcd/command.c and lib/silcclient/command.c
3202 and command_reply.c.
3204 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3205 the _from_client and _from_server functions. Affected file
3208 * Added silc_client_get_channel_by_id_resolve to the file
3209 lib/silcclient/silcapi.h to resolve channel information by
3210 its ID. Added also silc_client_get_channel_by_id that
3211 does not resolve it from the server.
3213 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3215 * Added SilcServerEntry context into the client library
3216 to represent one server. The INFO command now allocates
3217 these to save the resolved server info. For now on the
3218 client library will also keep information about servers,
3219 connected and resolved with INFO.
3221 The INFO command now allocates the SilcServerEntry context
3222 and saves the server info there. The COMMAND_REPLY in
3223 the INFO now returns the parameters to application in
3224 same order as defined in the protocol specification.
3226 The entries are cached in the client->server_cache.
3228 * The INFO command is now issued after received the Client ID
3229 from the server. Affected file lib/silcclient/client.c.
3231 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3232 to the application as the mode changer might be server.
3233 It is guaranteed that NULL is not returned anymore to the
3234 application. Affected file lib/silcclient/client_notify.c.
3236 The ID Type is now also passed to the application so that
3237 it can check whether the returned entry is SilcClientEntry
3240 Added new function silc_client_get_server_by_id to return
3241 the server entry by ID. Affected files are the
3242 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3244 * Do not create the channel in the Irssi SILC Client when issuing
3245 the JOIN command but when received the sucessful JOIN command
3246 reply. Otherwise the channel might get created even though we
3247 could not join it. The Affected file is
3248 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3250 * Fixed a channel joining bug in router. The router must also
3251 check the channel modes, invite and ban lists etc. when serving
3252 the JOIN command sent by normal server. Affected file is
3253 silcd/command.c. The router now resolves the client's
3254 information from the server who sent the JOIN command if it
3255 does not know it, and processes the JOIN command only after
3258 * Changed the SilcCommandCb to take new argument; void *context2.
3259 Affected file lib/silccore/silccommand.h
3261 The second argument in the command callbacks in the server now
3262 includes the SilcServerCommandReplyContext if the command was
3263 called as pending command callback from the command reply.
3264 Otherwise it is NULL. When called as pending the status of the
3265 command reply will be checked and if it was erronous the
3266 error will be sent to the original sender of the command.
3267 This way the client always receives the error messages even
3268 though the server was actually the one who received the error
3269 when it resent the command to router, for example. Affected
3270 files silcd/command[_reply].[ch].
3272 * Fixed sending WHOWAS command's error message to client if
3273 the requested client could not be found. It was missing.
3276 * Changed the CMODE and CUMODE commands reply arguments in the
3277 protocol specification. The Channel ID is now sent in both
3278 of the commands to identify the channel. Implemented this
3279 new feature to the client and server. Affected files
3280 lib/silcclient/command_reply.c and silcd/command.c.
3282 * Made better checks for invite and ban lists in the JOIN
3283 command in server. Affected file silcd/command.c.
3285 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3287 * The server now performs the incoming host IP/DNS lookup
3288 using the silc_socket_host_lookup and thus does not block
3289 the server anymore. Affected file silcd/server.c.
3291 * Completed the multi-thread support for SILC Scheduler in
3292 the lib/silcutil/silcschedule.c.
3294 * Fixed the configure.in.pre to detect the pthread correctly
3297 * Fixed a deadlock in silc_task_queue_wakeup in the file
3298 lib/silcutil/silctask.c.
3300 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3302 * Added new function silc_schedule_wakeup that is used in
3303 multi-threaded environment to wakeup the main thread's
3304 schduler. It needs to be used when a thread adds a new task
3305 or removes a task from task queues. After waking up, the
3306 scheduler will detect the task queue changes. If threads
3307 support is not compiled in this function has no effect.
3308 Implemented the wakeup mechanism to both Unix and WIN32
3309 systems. Affected files are lib/silcutil/silcschedule.[ch],
3310 lib/silcutil/unix/silcunixschedule.c and the
3311 lib/silcutil/win32/silcwin32schedule.c.
3313 * Added new function silc_task_queue_wakeup to wakeup the
3314 scheduler by the specified task queue. Affected file
3315 lib/silcutil/silctask.[ch].
3317 * The silc_socket_host_lookup_start now wakes up the scheduler
3318 after adding the timeout task. Affected file is
3319 lib/silcutil/silcsockconn.c.
3321 * The silc_socket_host_lookup is synchronous now if the threads
3322 support is not compiled in. However, the callback is still
3323 called asyncronously through the scheduler, anyway. Affected
3324 file lib/silcutil/silcsockconn.c.
3326 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3328 * Added new function silc_socket_host_lookup to perform
3329 asynchronous IP and FQDN lookups for the socket connection.
3330 Affected files lib/silcutil/silcsockconn.[ch].
3332 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3334 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3335 that may or may not compile the mutex support in.
3337 Changed the silc_mutex_alloc interface. It allocates the
3338 mutex now to the sent pointer and returns TRUE or FALSE.
3340 Affected file lib/silcutil/silcmutex.h.
3342 * Wrote the SILC Task Queue interface to support multi-threads.
3343 Affected file lib/silcutil/silctask.[ch].
3345 * Wrote the SILC Scheduler to support multi-threads. Affected
3346 file lib/silcutil/silcschedule.c.
3348 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3350 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3351 in lib/silcutil/win32/.
3353 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3355 * Defined SILC Mutex API and SILC Thread API and implemented
3356 them for Unix. Affected files are
3357 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3358 lib/silcutil/unix/silcunixmutex.c and
3359 lib/silcutil/unix/silcunixthread.c.
3361 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3363 * Fixed the silc_server_remove_clients_by_server's channel
3364 key re-generation. The hash table handling was incorrect
3365 and would not work with many channels. Affected file is
3368 * Fixed some memory leaks around the server code.
3370 * Rewrote the silc_server_get_users_on_channel to support IPv6
3371 based Client ID's. Affected file silcd/server.c.
3373 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3374 specification. However, a separate document must be written
3375 to define the detailed signing procedure and the payload
3376 associated with the flag. Defined the flag to the
3377 lib/silccore/silcchannel.h as well.
3379 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3381 * Changed the dynamic tables to static size tables in the
3382 lib/silccrypt/silchmac.c.
3384 * Removed GCC dependencies from the code. A patch by cras.
3386 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3388 * Do not show the error "Error receiving packet bla bla"
3389 in server if it really was not an error (-2 means that reading
3390 is pending). Affected file silcd/server.c.
3392 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3394 * Fixed a possible crash in silc_server_remove_clients_by_server
3395 in silcd/server.c. Fixed there also some memory leaks.
3397 * Fixed the silc_idlist_replace_client_id. It could replace
3398 wrong key in the hash table. Affected file silcd/idlist.c.
3400 * Do not check whether there are global users on the channel
3401 if the channel->global_users is FALSE. Affected functions
3402 silc_server_remove_from_one_channel and
3403 silc_server_remove_from_channels in silcd/server.c. Also,
3404 do not check if the removed client is local as we can be
3405 sure that global client was not removed from the channel
3406 and checking for global users is not needed.
3408 * The silc_server_remove_clients_by_server now re-generates
3409 the channel keys correctly for those channels that had
3410 clients removed from them. Affected file silcd/server.c.
3412 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3414 * Found the reason of random crashes in the server. We weren't
3415 ignoring the SIGPIPE signal (which can be sent in write())
3416 and it crashed the server. Affected file silcd/silcd.c.
3418 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3420 * Assure that sock->user_data is not NULL in the function
3421 silc_server_packet_send in silcd/packet_send.c.
3423 * Disconnect the remote connection if it could not be added
3424 to any ID lists in the server. The affected file is
3427 * Check in silc_server_packet_send[_real/dest] that the
3428 socket is not disconnecting and ignore the data if it is.
3429 Affected file silcd/packet_send.c.
3431 * Define inline to __inline on native WIN32 compilation.
3432 Affected file includes/silcwin32.h.
3434 * Added some explicit type casts for inline code since MSVC
3435 require them. Affected files lib/silcutil/silcbuffer.h,
3436 lib/trq/silcdlist.h and lib/trq/silclist.h.
3438 * Print warning in log files from now on if the packet
3439 decryption fails. Affected file silcd/server.c.
3441 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3443 * Changed the `say' client operation's interface to accept
3444 new `type' argument to indicate the type of the message sent
3445 by the library. The application may filter the library's
3446 messages according the type. The affected file is the
3447 lib/silcclient/silcapi.h.
3449 * Added two new functions to lib/silcclient/silcapi.h:
3450 silc_client_del_client and silc_client_del_client_by_id.
3451 Affected file lib/silcclient/idlist.c.
3453 * Moved the clientincludes.h from includes/ to silc/ and
3454 serverincludes.h from includes/ to silcd/.
3456 * The modes for the CMODE and CUMODE are now passed as
3457 uint32 for application with COMMAND_REPLY. The affected
3458 file is lib/silcclient/command_reply.c.
3460 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3462 * /WHOIS without arguments shows client's own information.
3463 Affected file lib/silcclient/command.c.
3465 * Changed PING to not accept any arguments. The specs
3466 says that client can ping only the connected server so
3467 requiring an argument is not needed. Affected file is
3468 lib/silcclient/command.c.
3470 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3472 * Fixed a fatal bug in private message sending and reception
3473 encryption and decryption when using private message keys.
3474 The implementation was incorrect and did not follow the
3475 specification. It causd that some of the message were
3476 lost since it did not use the sending and receiving keys
3477 as the protocol suggests. This has been fixed and will cause
3478 incompatibilities with older clients when sending private
3479 message encrypted with private message keys. Affected files
3480 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3481 and various other in Irssi SILC Client.
3483 Added `responder' boolean argument to the functions
3484 silc_client_add_private_message_key[_ske] to indicate when
3485 the key is added as responder or initiator of the key
3488 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3490 * Removed the silc_ske_check_version function and created
3491 a SilcSKECheckVersion callback. Added also a function
3492 silc_ske_set_callbacks that is now used to set all SKE
3493 callbacks. The callback functions are not given to
3494 the SKE functions anymore, but this function is used to
3497 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3499 * Added `silc_version' argument to the silc_client_alloc
3500 to define the version of the application for the library.
3501 The library will use the version string to compare it
3502 against the remote host's (usually a server) version
3503 string. Affected file lib/silcclient/silcapi.h
3505 * Added the KE protocol context to Key Agreement context
3506 in client library so that we can abort the SKE if it
3507 is in process when we get timeout. Affected file is
3508 lib/silcclient/client_keyagr.c.
3510 * Do not resolve the client ID forever if it returns in the
3511 first time that such client does not exist. This was done
3512 for example with private message. Affected file is
3513 lib/silcclient/client_prvmsg.c.
3515 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3517 * Do not add regex.h for WIN32. The affected file
3518 includes/silcincludes.h.
3520 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3521 not work yet 100%. It generates the DLL's automatically
3522 when compiling with --with-win32 under cygwin.
3524 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3526 * lib/contrib/regex.c is not compiled on WIN32.
3528 * Added silc_net_get_socket_opt function to the
3529 lib/silcutil/silcnet.h.
3531 * Added includes/silcwin32.h for WIN32 specific includes
3534 * Do not use ptime structure or any of the posix process
3535 functions on WIN32 in lib/silccrypt/silrng.c.
3537 * Added silc_gettimeofday to provide generic function
3538 for struct timeval on all platforms. Added the function
3539 to lib/silcutil/silcutil.h.
3541 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3543 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3544 library as they clearly belong there. As a plus side we
3545 can make the actual socket connection routines platform
3548 Added also new generic function silc_socket_read and
3549 silc_socket_write (that used to be silc_packet_[read/write].
3550 The implementation of these are platform specific.
3552 * Added WIN32 specific routines of silc_socket_[read/write]
3553 to lib/silcutil/win32/silcwin32sockconn.c.
3555 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3557 * Added preliminary support for native WIN32 compilation under
3558 cygwin (using the -mno-cygwin option for GCC) to the
3559 ./configure.in.pre. The --with-win32 now prepares the
3560 compilation for native WIN32.
3562 * Rewrote the SILC Scheduler interface in the file
3563 lib/silcutil/silcschedule.h. The scheduler is now context
3564 based and does not have anymore any global static scheduler.
3565 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3566 and created lib/silcutil/win32 directory for WIN32 based
3569 * Added Unix specific network routines to the
3570 lib/silcutil/unix/silcunixnet.c and the old
3571 lib/silcutil/silcnet.c includes now only generic routines.
3573 Added WIN32 specific network routines to the
3574 lib/silcutil/win32/silcwin32net.c.
3576 * Added Unix specific utility functions from the
3577 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3579 * Added WIN32 SILC Scheduler to the file
3580 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3583 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3585 * Do not handle JOIN notify in the server if the target client
3586 is not registered (idata->registered == FALSE). The affected
3587 file is silcd/packet_receive.c.
3589 * Update the nickrec->founder in event_cumode in the Irssi SILC
3590 client. Affected file irssi/src/silc/core/silc-channels.c.
3592 * Fixed the CUMODE_CHANGE notify handling in the server when
3593 server and router are announcing their clients on channels.
3594 Now the mode changes are saved and notified correctly. The
3595 affected file is /silcd/packet_receive.c.
3597 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3598 They really did not replace the cache entry in the ID Cache.
3599 Now they do that. Affected file silcd/idlist.c.
3601 * Fixed the KICK notify handling in the Irssi SILC client to
3602 update the channel records so that the kicked client does not
3603 appear to be on the channel. The affected file is
3604 irssi/src/silc/core/silc-channels.c.
3606 * Always update the conn->current_channel when executing command
3607 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3609 * Fixed the KILL notify handling in Irssi SILC client to remove
3610 the killed client on all channels.
3612 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3614 * Fixed the silc_parse_command_line to remove extra spaces
3615 from the start and end of the arguments. Affected file is
3616 lib/silcutil/silcutil.c.
3618 * Cancel and free any active protocol in the function
3619 silc_server_close_connection. Affected file silcd/server.c.
3621 * Cancel and free any active protocol in the function
3622 silc_client_close_connction. Affected file is
3623 lib/silcclient/client.c.
3625 * Do not execute the KILL command for clients that are in
3626 history (ie. they are not in the network). Affected file is
3629 * Fixed KILL notify handling, client does not crash anymore.
3630 Affected file irssi/src/silc/core/silc-channels.c.
3632 * Reduced the default packet buffer size from 2048 to 1024 in
3633 lib/silccore/silcpacket.c.
3635 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3636 counter to the SKE context that is incresed when the SKE library
3637 performs async operation outside the library. If the outside
3638 process frees the SKE context and FREED status will be set
3639 and the library will detect after the sync operation that the
3640 libary is freed. The affected files are
3641 lib/silcske/silcske[_status].[ch].
3643 * Resolve the client entry information in the function
3644 silc_client_channel_message to assure that NULL pointer is not
3645 passed as client entry to the application. */
3647 * Fixed the task timeout calculation to assure that there is
3648 never negative timeouts. The affected file is
3649 lib/silcutil/silcschedule.c.
3651 * Fixed the channel user mode notification sending in server.
3652 It was sent point-to-point to the router (or to server by router)
3653 but it needs to be destined to a channel. The routines now
3654 supports sending the channel user mode notifys to the channels
3655 when announcing clients and channels. Affected files are
3656 silcd/server.c and silcd/packet_receive.c.
3658 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3659 It did not actually replace the old channel entry in the cache.
3660 Affected file lib/silcclient/client_notify.c.
3662 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3664 * Fixed a possible crash in silc_packet_send_prepare. It now
3665 assures always that there is enough space in the buffer and
3666 at the tail area of the buffer (for MAC).
3668 Fixed the inbound buffer reallocation in silc_packet_read.
3669 It was old code and did not handle the reallocation correctly.
3672 The affected file is lib/silccore/silcpacket.c.
3674 * Fixed buffer overflow in silc_parse_nickname in the file
3675 lib/silcutil/silcutil.c.
3677 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3679 * make install generates new server keys only if there is not
3682 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3684 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3685 Added check that if the NOREPLY is set then we will not send
3686 the away message. This avoids infinite loop of away messages
3687 if both clients are away. The affected file is
3688 lib/silcclient/client_prvmsg.c.
3690 * Fixed client crash if /NICK was given without arguments.
3691 Affected file lib/silcclient/command.c.
3693 * Server does not send the invite list in INVITE command back
3694 to the client if the list was not altered. Added this notion
3695 to the protocol spec as well. Affected file silcd/command.c.
3697 Fixed possible crash in INVITE command by checking the
3698 value of silc_server_get_client_route command.
3700 * Fixed the INVITE notify type handling. The arguments are now
3701 taken in correct order and client does not crash. The affected
3702 file is irssi/src/silc/core/silc-channels.c.
3704 Removed the "Inviting xxx to channel" message from the
3705 client library away and let the application handle it.
3706 Affected file lib/silcclient/command.c. Added that message
3707 to Irssi SILC client's message formats.
3709 * Fixed CMODE command crash in client. It now checks the
3710 amount of arguments correctly and does not crash. The affected
3711 file is lib/silcclient/command.c.
3713 * Do not create new channel automatically in silc_channels_join
3714 but check whether the channel by that name already exists.
3715 Affected file irssi/silc/core/silc-channels.c.
3717 * Do not send the SERVER_SIGNOFF to router if the disconnected
3718 entity was the router. Affected file silcd/server.c.
3720 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3721 SILC client as it was missing from there.
3723 Added the handling of the KICK notify to the Irssi SILC client
3724 as it was missing. Added "you have been kicked" message to
3725 Irssi SILC client's message modules formats.
3727 Added the handing of the KILL notify to the Irssi SILC client
3728 as it was missing. Added the kill message module formats
3731 The affected file is irssi/src/silc/core/silc-channels.c.
3733 * The router did not save the channel mode the server announced.
3734 Affected file silcd/packet_receive.c.
3736 * Fixed a possible crash in INFO command in server. If the
3737 server did not provide the server info it crashed. Affected
3738 file silcd/command.c.
3740 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3742 * Fixed the GETKEY command in the server to check also the
3743 global list. Otherwise the GETKEY would not work correctly
3744 in normal SILC server. Affected file silcd/command.c.
3746 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3748 * Fixed GETKEY crash, it crashed if the command did not succseed.
3750 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3752 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3753 is now real and not just an macro interface to GMP.
3755 Removed the entire GMP from the source tree and imported new
3756 NSS MPI library instead. Reason for removing GMP is that it is
3757 extremely large and compiles extremely slow. The NSS MPI
3758 is only a few files and compiles in less than 10 seconds.
3759 The speed is also about the same as GMP. The MPI is imported
3760 to lib/silcmath/mpi.
3762 If the system has GMP installed we will still use the GMP.
3763 If it is not then the NSS MPI will be compiled.
3765 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3767 * Merged a long nickname (127 characters long) crash bugfix from
3768 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3770 * Merged a freed memory reference bugfix from Irssi CVS tree.
3771 Affected file irssi/src/core/commands.c.
3773 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Added the server's public key sving and verification to the
3776 server when performing the SKE. This was missing and the
3777 remote server's (or router's) public key was accepted without
3778 checking whether we have it previously or trust it at all.
3779 Affected file silcd/protocol.c.
3781 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3783 * Check in the silc_server_timeout_remote if protocol is active
3784 and make sure that the protocol's final callback is called so
3785 that all memory if freed. Affected file silcd/server.c.
3787 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3789 * silc_server_whois_send_reply crashed the server if the nickname
3790 was 127 characters long. Affected file silcd/command.c.
3792 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3794 * Added sanity check to the silc_server_new_client. If the hostname
3795 is provided inside username then check that the provided hostname
3796 really is the same as the resolved one. If the hostname was not
3797 resolved then check it from the public key. Affected file is
3798 silcd/packet_receive.c.
3800 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3801 if the server disconnected us and the connection is not valid
3802 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3804 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3805 the library to the lib/silcutil/silcutil.[ch].
3807 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Close log file after open. Affected file
3810 lib/silcutil/silclog.c.
3812 * Check whether sock == NULL in silc_client_send_packet and return
3813 if it is. Affected file lib/silcclient/silcclient.c.
3815 * Check rec->entry == NULL in the Irssi SILC Client before
3816 sending the channel message. Affecte file is
3817 irssi/src/silc/core/silc-servers.c.
3819 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Merged a splitted window bugfix from Irssi CVS tree. The
3822 affected file is irssi/src/fe-text/textbuffer-view.c.
3824 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3825 It did not print nickname.
3827 * Improved the distributions system a bit.
3829 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3831 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3832 irssi/src/fe-text/gui-window.c.
3834 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3835 to in-active server. The affected file is
3836 irssi/src/silc/core/client_ops.c.
3838 * Resolve the client in USERS command reply if the entry does
3839 not have username resolved. The affected file is
3840 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3841 command to WHOIS command to really resolve stuff. The USERS
3842 is not used any more in any critical section so WHOIS can
3843 be used even though it might be slower than IDENTIFY.
3845 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3848 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3850 * Changed the protocol API a bit more consistent in the
3851 lib/silccore/silcprotocol.[ch].
3853 * Changed the following headers to ROBODoc format:
3855 lib/silccore/silcpayload.h
3856 lib/silccore/silcprotocol.h
3857 lib/silccore/silcsockconn.h
3859 All core library headers are now formatted.
3861 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3863 * Fixed a bug in Irssi SILC client; do not show that you are
3864 server/router operator if you really are not. Affected file is
3865 irssi/src/silc/core/client_ops.c.
3867 * Renamed silc_command_free_payload to silc_command_payload_free.
3868 Affected file lib/silccore/silccommand.h
3870 * Added silcmath.h to include the prototoypes of various routines
3871 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3874 * Changed the following headers to ROBODoc format:
3876 lib/silccore/silcchannel.h
3877 lib/silccore/silccommand.h
3878 lib/silccore/silcid.h
3879 lib/silccore/silcidcache.h
3880 lib/silccore/silcmode.h
3881 lib/silccore/silcnotify.h
3882 lib/silccore/silcpacket.h
3883 lib/silcmath/silcmath.h
3885 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3887 * Added checking to the server code not to start the server if
3888 ciphers and stuff are not configured properly. Affected files
3889 silcd/serverconfig.[h] and silcd/server.c.
3891 * Changed the layout of the header files of the public interfaces
3892 in the SILC libraries. The new layout supports ROBODoc
3893 documentation tool (and some others) so that it is easy to create
3894 a library reference manual. All the other headers and source
3895 code must still follow the CodingStyle document. Also source
3896 code must not include these ROBODoc stuffs, only the headers.
3897 Furthermore, all public interface headers must now be named
3898 by using `silc' prefix, example: silcapi.h, silccipher.h.
3899 Some files were renamed due to this. All the other headers
3900 must not be used as public interfaces. I will update the
3901 CodingStyle document later. Changed following headers, so far:
3903 lib/silcclient/silcapi.h
3904 lib/silccore/silcauth.h
3905 lib/silccore/silcprivate.h
3906 lib/silccrypt/silcdh.h
3908 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3912 * Removed silc_client_packet_send_flush from the client library
3913 as it is not needed. Affected file lib/silcclient/client.[ch].
3915 * Added printing of message of unresolved authentication method
3916 to the Irssi SILC client. Added it to the module formats.
3917 Removed the same message from the client library.
3919 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * Added new distribution feature, DISTLABEL. Every distribution
3922 can define own preprocessor label that can be used in the
3923 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3924 file distributions, acconfig.h.pre and prepare.
3926 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3928 * Added Makefile.defines_int to include the actual definitions
3929 for Makefile.defines.in. Tested the new distribution system,
3930 created distributions and tested installation.
3932 * Added AWAY message printing to the Irssi SILC client. Added
3933 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3935 * Added SCONNECT command to call the SILC's CONNECT command.
3936 Cannot use CONNECT directly since Irssi uses that internally.
3937 Affected file irssi/src/silc/core/silc-servers.c.
3939 Added ACTION local command. It is same as ME command but takes
3940 the channel as mandatory argument.
3942 Rewrote some of the Irssi's help files to suite for SILC
3945 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3947 * Added Makefile.defines[.in] that should for now on be included
3948 in all Makefile.am file in the source tree. That file includes
3949 all common compilation definitions for SILC source tree.
3951 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3953 * Minor changes to the ./prepare script to change the package
3954 name according the distribution name to the configure.in.
3956 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3958 * Created new distribution system. Added file `distributions'
3959 that defines all the distributions that can be created out of
3960 the SILC source tree. The ./prepare script now reads that
3961 file to determine how to prepare the distributions. The
3962 first argument to the ./prepare is the name of the distribution
3963 and second is the version of the distribution. If given
3964 without arguments it creates the default (toolkit) distribution
3965 with the default version (defined in ./prepare).
3967 All Makefile.am files that are subject to the distributions
3968 are now named as Makefile.am.pre. These are ./Makefile.am
3969 and lib/Makefile.am. Others may be changed later.
3971 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3973 * Added invite list, ban list, some key management and connection
3974 error message printing to module formats in the Irssi SILC client.
3976 * Added new silc_client_set_away_message to set the away message
3977 that is back to the person who sent private message. The
3978 affected file lib/silcclient/silcapi.h and the
3979 lib/silcclient/client_prvmsg.c.
3981 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3983 * Fixed the private message sending in the Irssi SILC client,
3984 added local command KEY to the Irssi SILC client.
3986 Added key management and key agreement message formats to the
3987 irssi/src/fe-common/silc/module-formats.[ch].
3989 Added USERS (alias WHO) printing, server/router operator
3990 indication and LIST command printing to the module formats.
3992 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3994 * Fixed channel joining notify handling, cumode notify handling
3995 from Irssi SILC client.
3997 * Added SILC specific module-formats to the Irssi SILC client so
3998 that SILC specific message hilighting, colors etc is possible.
3999 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4001 Added channel mode, channel user mode, actions, notices,
4002 whois and whowas printing to the the module-formats.c.
4004 * Fixed a bug in channel deletion in the server. The channel
4005 is not left to the cache even if the channel founder auth mode
4006 is set when there are no users anymore on the channel. Affected
4007 file silcd/server.c.
4009 * The silc_net_localhost now resolves the entire hostname including
4010 the domain name. Affected file lib/silcutil/silcnet.c.
4012 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Changed the ask_passphrase client operation to be ascynchronous.
4015 It has now a completion callback and a context that the
4016 application must call after it has got the passphrase from
4017 the user. Affected files lib/silcclient/silcapi.h,
4018 lib/silcclient/protocol.c, lib/silcclient/command.c and
4021 Added SilcAskPassphrase callback that the application calls
4022 to deliver the passphrase to the library.
4024 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4025 The public key verification and especially a certificate
4026 verification is asynchronous procedure.
4028 Added new SILC_SKE_STATUS_PENDING status to indicate the
4029 request is pending and a callback will be called to finalize
4032 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4033 indicate that remote end did not send its public key (or
4034 certificate), even though we require it. Added check for this
4035 condition in the SKE. This was a security bug, now fixed.
4037 Defined new SilcSKEVerifyCbCompletion callback that is called
4038 when the verification process is completed.
4040 The affected files lib/silcske/silcske_status.h and
4041 lib/silcske/silcske.[ch].
4043 * Changed the verify_public_key client operation to be async
4044 as well. Defined SilcVerifyPublicKey callback that is used to
4045 indicate the success of the public key verification process.
4047 Changed the server and client to use the new async client
4050 * Changed the Irssi SILC client's internal scheduler to be called
4051 twice as many times as it used to be. As a result the client
4052 should be a bit faster now. Affected file is
4053 irssi/src/silc/core/silc-core.c.
4055 * Added support to Irssi SILC client of asynchronous public key
4056 verification and passphrase inquiry. Affected file is
4057 irssi/src/silc/core/silc-core.c.
4059 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4061 * Do not say "You have left channel %s" in client library.
4062 Moved it to the application. Affected files are
4063 lib/silcclient/command.c and silc/client_ops.c.
4065 * Fixed silc_client_get_clients. Command context was not
4066 duplicated and was freed memory in the callback. Affected
4067 file lib/silcclient/idlist.c.
4069 * Do not say "you are now talking..." on JOIN command in the
4070 client library. The appliation must handle it.
4072 * Do not say ".. changed topic to" in command reply in the
4073 client libary. The application must handle it.
4075 * Fixed TOPIC command sending in the client library.
4077 * Fixed a memory leak in silc_client_command_free in the file
4078 lib/silcclient/command.c.
4080 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4082 * Imported a modified version of Irssi client to the source tree.
4083 The Irssi will be used to create a new client called
4084 Irssi SILC. Imported to irssi/.
4086 Added silc_core_init_finish function to the Irssi. Affected
4087 file irssi/configure.in.
4089 A lot changes in the Makefile.ams around the irssi tree.
4091 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4093 * Do not rehash if the new size is same as the old size of the
4094 hash table, in the silc_hash_table_rehash*. The affected file
4095 lib/silcutil/silchashtable.c.
4097 * Replaced hash_table_del_by_context calls from the server
4098 (when channel->user_list and client->channels) to the
4099 hash_table_del as it is sufficient and faster.
4101 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4103 * Added silc_hash_table_list, silc_hash_table_get and the
4104 SilcHashTableList structure to provide an alternative way to
4105 traverse the hash table. The affected files are
4106 lib/silcutil/silchashtable.[ch].
4108 * Changed the server's idlist routines to use the hash table
4109 routines to optimize the code.
4111 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4113 * Replaced the client entry's `channel' list and channel entry's
4114 `user_list' list to hash tables for optimized lookup. Changed
4115 the code to use the hash table interface around the code.
4116 Affected file lib/silcd/idlist.[ch].
4118 * Added `auto_rehash' boolean argument to the function
4119 silc_hash_table_alloc to indicate whether the hash table should
4120 auto-rehash when it thinks is appropriate time. It will
4121 increase the hash table size if the there is twice as much
4122 entries in the table than the size of the table, and will
4123 decrease the size if there are twice as less entries than
4124 the size of the table.
4126 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4130 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4132 * silc_idcache_purge_by_context deletes the entry now by context
4133 as it is supposed to do. Affected file lib/silccore/idcache.c.
4135 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4136 client is not anymore valid (WHOWAS givens the info) and not
4137 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4139 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4141 * Removed the `data' and `data_len' arguments from the ID Cache
4142 interfaces and added `name' argument. ID Cache does not handle
4143 anymore the binary data only a names associated with given ID.
4145 * When hashing a Client ID with silc_hash_id the entire ID is
4146 not hashed anymore, instead only the hash of the Client ID is
4147 hashed. This way we can access the Client ID from the cache
4148 with Client ID but with the hash of the ID (which is a hash of
4149 the nickname) as well without any difference in performance.
4151 Added also silc_idcache_find_by_id_one_ext to do one on one
4152 searching when we have the actual ID. Added also function
4153 silc_hash_client_id_compare. The affected files are
4154 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4156 * When hashing the name associated with a ID it is always done
4157 in lowercase. This way we can access the cache without worrying
4158 about case-sensitivity, even though, for example nicknames are
4161 * Fixed a bug in server with channel message sending. It put
4162 wrong ID type as destination ID. The affected file
4163 silcd/packet_send.c.
4165 * silc_idcache_del_by_context now deletes from all hash tables
4166 by context. Affected file lib/silccore/idcache.c.
4168 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4170 * Changed the client library to use the new ID Cache interface.
4171 Changes around the source tree.
4173 * Added silc_hash_table_rehash_ext to rehash with specific
4174 hash function. Affected file lib/silcutil/silchashtable.[ch].
4176 * Added silc_hash_string_compare to compare two strings in the
4177 hash table. Affected file lib/silcutil/silcutil.[ch].
4179 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4181 * Added new function silc_idcache_del_by_context into the
4182 lib/silccore/idcache.[ch].
4184 * Changed the server's ID list routines to use the new ID Cache
4185 interface. Changes around the source tree.
4187 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4189 * Added silc_hash_table_del[_by_context]_ext functions in to the
4190 lib/silcutil/silchashtable.[ch].
4192 Removed silc_hash_table_find_all* routines and added new
4193 silc_hash_table_find_foreach to replace them.
4195 Added silc_hash_table_replace_ext function as extended
4196 replacing function. Separated the simple hash table interface
4197 from the extended hash table interface in the file
4198 lib/silcutil/silchashtable.h.
4200 * Fixed minor bugs and changed it to use some of the new
4201 hash table functions in lib/silccore/idcache.c
4203 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Added new function silc_hash_table_find_all to return all keys
4206 in the hash table by the specified key. As the hash table is
4207 collision resistant it also makes it possible to have several
4208 duplicate keys in the hash table. This function may be used to
4209 find all of the keys from the hash.
4211 Added user_context arguments to the SilcHashFunction,
4212 SilcHashCompare and SilcHashDestructor to deliver user specified
4215 Added new fuctions silc_hash_table_find[_all]_ext to do
4216 extended lookup with specified hash and compare functions and
4217 specified user contexts.
4219 Added new function silc_hash_table_add_ext to add the key
4220 with specified hash function and user context.
4222 Added new function silc_hash_table_foreach to traverse all
4223 entrys in the hash table. Added SilcHashForeach callback
4226 Added new function silc_hash_table_del_by_context to delete
4227 the entry only if the context associated with the key matches.
4229 Affected files are lib/silcutil/silchashtable.[ch].
4231 * Removed silc_hash_[server/client/channel]_id and added just
4232 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4233 silc_hash_id_compare to compare two ID's using as the hash table
4234 comparison function. Added also silc_hash_data to hash
4235 binary data and silc_hash_data_compare to compare it.
4237 * Removed silc_idlist_find_client_by_hash as it is not needed
4238 anymore. Affected file silcd/idlist.[ch].
4240 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4241 to use internally the SilcHashTable. The new ID Cache is a lot
4242 faster than the old one. Some of the ID Cache interface was also
4243 rewritten and obsolete and stupid functions were removed.
4245 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4247 * Added entry_count field to the SilcHashTable to keep the number
4248 of the entries in the table. Implemented the function
4249 silc_hash_table_rehash. Added new function
4250 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4252 Fixed a minor bug in silc_hash_table_free.
4254 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4255 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4256 into the lib/silcutil/silcutil.[ch].
4258 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4260 * Implemented a collision resistant hash table into the
4261 lib/silcutil/silchashtable[ch]. See the header and the source
4262 for the SilcHashTable API.
4264 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4266 * Merged dotconf version 1.0.2 into lib/dotconf.
4268 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * Do not compile anything in lib/silcsim/* if the SIM support
4271 is not enabled. The tree should now compile without problems
4274 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4276 * Compiled the SILC under cygwin. Compiled and tested briefly
4277 without problems. More tests needed. The SIMs didn't compile
4280 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4282 * Fixed possible crash in silc_get_username in the
4283 lib/silcutil/silcutil.c.
4285 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4287 * Fixed a va_arg in silc/client_ops.c.
4289 * Oops, RC5 routines were named AES and caused some problems
4290 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4292 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4294 * Added new SilcIDIP structure into the lib/silccore/id.h and
4295 replaced the old `ip' fields from all SILC ID's to that type.
4296 This is a step towards IPv6 support.
4298 The silc_id_get_len takes now the ID as an extra argument.
4299 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4300 both IPv4 and IPv6 based ID's.
4302 The affected files are lib/silccore/id.[ch] and other files
4303 around the tree using these routines.
4305 * Removed the ID length arguments in server from various
4306 silc_server_send_notify_* routines -> they are not needed
4309 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4311 * Fixed memory leak in silc_encode_pem_file in the file
4312 lib/silcutil/silcutil.c.
4314 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4316 * Check minor version as well in the SKE. Affected files are
4317 silcd/protocol.c and lib/silcclient/protocol.c.
4319 * Added --identifier option to the server so that an identifier
4320 can be when creating the public key for the server. Affected
4321 file is silcd/silcd.c.
4323 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4324 lib/silccrypt/silcpkcs.c.
4326 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4328 * Register default ciphers and stuff when using -C option with
4329 the server. Affected file sildc/silcd.c.
4331 * Put back the servers public key filename format, it is better
4332 than the new one. For now, the client keys are saved with the
4333 new filename format. The affected file silc/client_ops.c.
4335 * Implemented the Cipher API for the rest of the ciphers that
4336 did not implement it or implemented it the wrong way.
4338 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4340 * Register default ciphers and stuff when using the -S option
4341 in the client. Affected file silc/silc.c. Same also when
4342 creating new key pair with -C option.
4344 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4346 * Fixed the silc_verify_public_key client operation function to
4347 save the public keys differently. The fingerprint is now
4348 used as filename and not the hostname. This way also the
4349 client keys are saved uniquely and not with hostnames. The
4350 affected file is silc/client_ops.c.
4352 * Trimmed the silc_hash_fingerprint function to remove extra
4353 whitespaces from the end of the fingerprint. The affected
4354 file is lib/silccrypt/silchash.c.
4358 * Added silc_cipher_register_default function to register all
4359 default ciphers. It can be used when configuration files
4360 does not exist and the application does not want any specific
4361 ciphers in any specific order.
4363 The SilcDList is now used as silc_cipher_list dynamically
4364 allocated cipher list. Removed the static list all together
4365 and now all ciphers must be allocated to the dynamic list.
4366 The silc_cipher_alloc routine was changed to check only the
4369 All silc_cipher_* routines that used to return int returns
4372 The affected files lib/silccrypt/silccrypt.[ch].
4374 * The same thing was done to silc_hash_* as for silc_cipher_*
4375 routines. Affected files lib/silccrypt/silchash.[ch].
4377 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4378 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4379 Added also silc_pkcs_[un]register[_default] functions.
4380 Removed the data_context from the PKCS API.
4382 * Added silc_hmac_register_default function to register default
4383 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4384 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4385 to unregister all hmacs at once.
4387 * Register the default ciphers, hash functions, PKCSs and HMACs
4388 if client's configuration file does not exist. The affected
4391 * The client did not load the hash functions from the SIM
4392 modules at all. Added support for this. Affected file is
4393 silc/clientconfig.c.
4395 * When decoding public key with silc_pkcs_public_key_decode, check
4396 the supported algorithm only if PKCS are registered. Affected
4397 file lib/silccrypt/silcpkcs.c. The same was done with the
4398 silc_pkcs_private_key_decode.
4400 * Fixed the SILC List routines to keep the list always in order.
4401 It used to change the list's order when traversing the list but
4402 not it preserves the order. Affected file lib/trq/silclist.h.
4404 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Added the client library to use the SilcSocketConnection's
4407 reference counter (by silc_socket_dup) to prevent the bug that
4408 the socket object may be freed underneath async operation.
4410 * The name resolv library checking fixes in the configure.in.pre.
4413 * Created new version of the protocol drafts for future
4414 development. The -03 drafts are the ones that will be changed
4415 in the trunk now and the -02 will remain as they are.
4417 * Send list of CUMODE notifys to the router when announcing
4418 the channel users to the router. Affected file silcd/server.c.
4419 If the router receiving channel founder CUMODE for a channel
4420 that already has channel founder it will send CUMODE notify
4421 to the sender to remove the channel founder rights from the
4422 announced client. Affected file silcd/packet_receive.c.
4424 * The CUMODE notify may now use Server ID as well as the entity
4425 who changes the mode. Updated protocool specs.
4427 * Updated INSTALL and README files.
4429 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * New web pages in the http://silc.pspt.fi. The pages was
4436 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4438 * Implemented the [DenyConnectin] config section in the server.
4439 Added silc_server_config_denied_conn to check whether incoming
4440 connection is denied. Affected file silcd/serverconfig.[ch].
4442 * Do not check the ports when checking the incoming configuration
4443 data if the port is 0, meaning any. Affected file is
4444 silcd/serverconfig.c.
4446 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4448 * Fixed buffer overflow in silc_string_compare in the file
4449 lib/silcutil/silcutil.c.
4451 * Fixed double free in silc_server_command_leave in the file
4454 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4456 * Fixed the version checking in the server. Affected file is
4459 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4461 * Fixed the configuration data fetching when accepting new
4462 connections in the server. Affected file silcd/server.c.
4464 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4466 * Added `sender_entry' argument to the function
4467 silc_server_packet_relay_to_channel so that we can check
4468 whether some destination actually belongs to the same route
4469 the sender belongs (ie, we must not resend the packet to the
4470 sender). Affected file silcd/packet_send.[ch].
4472 * Added `servername' field to the SilcClientEntry in the server
4473 to hold the name of the server where client is from. Affected
4474 file is silcd/idlist.h.
4476 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Moved the channel message encrypting in the router betwen
4479 router connections from silc_server_channel_message to the
4480 silc_server_packet_relay_to_channel since we want to check
4481 whether we have anybody channel before encrypting anything.
4482 Affected files silcd/packet_[receive/send].c.
4484 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4486 * Fixed the [AdminConnection] server config section to support
4487 multiple entries. Affected file silcd/serverconfig.c.
4489 * Added support into the server to check the validity of the
4490 incoming connection before executing any KE or authentication
4493 * The connection configuration is now saved to the KE and
4494 connection auth protocol contexts and not fetched anymore in
4495 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4497 * The local hosts listenning address and port is also resolved
4498 now when starting the server. We want to have the socket object
4499 to include the real address and port for the listener. Added
4500 new function silc_net_check_local_by_sock into the files
4501 lib/silcutil/silcnet.[ch].
4503 * Fixed a broadcast bug in server -> do not broadcast if we
4506 * Fixed a routing bug. Do not route broadcast packets ever.
4507 Broadcast packets must be processed always and not routed since
4508 they may be destined to some other host than yourself and thus
4509 would get routed without no good reason. Affected file is
4512 * Added function silc_server_config_is_primary_route to check
4513 whether primary router connection has been configured (a router
4514 configuration that we are initiating). If there is not, we
4515 will assume that there is only two routers in the SILC network
4516 and we will use the incoming router connection as our primary
4517 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4519 * Changed the order of the broadcasting. Broadcast _after_ the
4520 packet has been processed not before. Affected file is
4523 * Fixed a [ClientConnection] parsing bug. The port was never
4524 parsed correctly thus resulting to port 0. Affected file
4525 silcd/serverconfig.c.
4527 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4528 argument and did not set the broadcast packet flag. Affected
4529 file silcd/packet_send.c. Fixed same bug in the function
4530 silc_server_send_notify as well.
4532 * If we receive NEW_ID packet for our own ID in the server, ignore
4535 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4539 * Removed the nickname from the Private Message Payload.
4540 Updated the code and the protocol specs.
4542 * Updated protocol specs for submitting to the IETF.
4544 * Tweaked the Random Number Generator a bit. Affected file
4545 lib/silccrypt/silcrng.c. Exported a new function
4546 silc_rng_[global]_add_noise which can be used to add more
4549 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4551 * Do not parse packets with different timeout when protocol
4552 is active -> may cause problem with rekey. Affected file
4555 * When server receives signoff notify it must not create
4556 new channel key if the client is on any channels since the
4557 sender of the signoff notify will create it.
4559 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Added printing of error messages during SKE protocol from the
4562 failure packet sent by server during SKE. Affected file
4565 * Removed the client's failure_callback handling with timeout
4566 and handle it immediately when received.
4568 * The SKE library returned wrong type in SUCCESS and FAILURE
4569 packets. They must be 32 bit MSB not 16 bit MSB.
4571 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Ok, rewrote the logic of the re-key and now it seems to work.
4574 I tested it on high traffic with frequent re-keys without
4575 problems. Added hmac_receive (and renamed hmac to hmac_send)
4576 in SilcClientConnection in lib/silcclient/client.h and
4577 in SilcIDListData in silcd/idlist.h. Also, removed the
4578 SilcPacketParserContext's cipher and hmac fields as they are
4579 not needed anymore and actually caused some problems when
4580 the ciphers and hmac's changed underneath the packet parser.
4582 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4584 * If re-key protocol is active then process the incoming packets
4585 synchronously since we must assure that icoming packets encrypted
4586 with the old key is processed before the new keys is set to
4587 use. This is true other packets than for REKEY packets.
4588 Affected file silcd/server.c. The same was done to client library
4589 as well, affected file lib/silcclient/client.c.
4591 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Fixed bug in client and server to accept the force send if
4594 the packet is send from silc_[server/client]_packet_process
4595 function. Otherwise the packets are never delivered, oops.
4597 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * Disable force sending of packets when REKEY protocol is active.
4600 We must assure that no packet is sent directly when rekey is
4601 performed. All packets must be sent through packet queue.
4602 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4603 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4604 function is silc_[server/client]_packet_send_real to check
4607 * Replaced the SIM paths from example config files to
4608 /usr/local/modules. Also, make install creates now
4609 /usr/local/silc/logs directory to hold all the SILC server
4612 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Made the configure.in.pre work on Solaris. Patch by salo.
4616 * Made all ciphers compatible with non-x86 machines. Defined
4617 CBC mode macros into lib/silccrypt/ciphers_def.h.
4619 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4621 * Fixed the make install.
4623 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4625 * When MAC computation fails the silc_packet_decrypt returned 0
4626 even though it was supposed to return -1. Fixed this. The
4627 affected file is lib/silccore/silcpacket.c.
4629 * Do not replace the config files in /etc/silc (in make install)
4630 if they already exist. Affected file ./Makefile.am.
4632 * Do not send re-key packets immediately but through packet queue.
4633 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4635 * Changed silc_net_check_host_by_sock to return FALSE if the
4636 IP/DNS could not be resolved. Though, it returns the IP address
4637 now even if it could not resolve it (but returns also FALSE).
4638 Affected file lib/silcutil/silcnet.[ch].
4640 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4642 * Added silc_pkcs_decode_identifier to decode the public key's
4643 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4644 Added also silc_pkcs_free_identifier. Added also new context
4645 SilcPublicKeyIdentifier.
4647 * Added -S option to the silc client. It is used to dump the
4648 contents of the specified public key file.
4650 * Changed the PKCS api to return the public key length when
4651 setting the public key.
4653 * Fixed a fatal bug in the public and private key file loading.
4654 Affected file lib/silccrypt/silcpkcs.c.
4656 * Execute the packet parsing for client with zero (0) timeout
4657 if the protocol is active. Affected file silcd/server.c.
4659 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Made the key generation options to the silcd program. Added
4662 -C option, equivalent to client's option.
4664 * Added new [ServerKeys] config section to the server. It
4665 configures the server's public and private key.
4667 * Defined generic Public Key Payload into the protocol
4668 specification to send specific type of public keys and
4671 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4672 public key or certificate.
4674 * Implemented the GETKEY command to the server and to the
4675 client library and on user interface.
4677 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4679 * Made preliminary `make install' work.

4696 state of the protocol. Affected file is
4697 lib/silccore/silcprotocol.[ch].
4699 * Added the re-key support with and without PFS to the client
4700 library. Re-key is performed once in an hour, by default.
4702 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4703 Added silc_client_rekey_callback and silc_client_rekey_final.
4704 Affected files are lib/silcclient/protocol.[ch] and

4708 SilcClientConnection structure; not needed. Affected file is
4709 lib/silcclient/client.h.
4713 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4715 * Do not ask whether user wants to use the negotiated private key
4716 for private messages, just use it. Affected file is
4717 silc/local_command.c.
4719 * Added `send_enc_key' and `enc_key_len' fields to the
4720 SilcIDListData structure since they are needed in the re-key
4721 phase. Affected file is silcd/idlist.[ch].
4723 * Implemented the simple re-key protocol into the server.

4735 the PFS is to be performed in the re-key. Affected file is
4738 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4740 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4741 int64 of at least the xintXX size. If void * is less that 4
4742 bytes uint32 * will be used. Defined bool as boolean.
4744 * Changed _ALL_ unsigned long and unsigned int to uint32,
4745 unsgined short to uint16 in the source tree.
4747 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4748 not handle clients that has entry->data.registered == FALSE.
4749 They are not in the network anymore. Affected file is
4752 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4754 * Implemented the sending of the SERVER_SIGNOFF notify in the
4755 server. Affected file is silcd/server.c.
4757 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4758 Added also silc_notify_payload_encode_args into the
4759 lib/silccore/silcnotify.[ch].
4761 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4762 Affected file silcd/packet_receive.c.
4764 * Implemented the SERVER_SIGNOFF notify handling in the client
4765 library. Affected file lib/silcclient/client_notify.c. Also,
4766 implemnted the printing of the SERVER_SIGNOFF info to the
4767 application. Affected file silc/client_ops.c.
4769 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4770 if the deleting was successful. Affected file silcd/idlist.[ch].
4772 * Added support for public key authentication in the connection
4773 authentication protocol in the client library. Affected file
4774 lib/silcclient/protocol.c.
4776 * Changed the server's silc_idlist_get_clients_by_* interface
4777 to support already allocated array so that new entries may be
4778 added to pre-allocated array. Affected file silcd/idlist.[ch].
4779 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4780 and command replies.
4782 * All command reply functions in the server now calls the
4783 pending command callback even if error occured. This way the
4784 error will be delivered to the client as well. Affected files
4785 silcd/command.c and silcd/command_reply.c.
4787 * Fixed INFO command to return local server's info if no server
4788 was provided. Affected file lib/silcclient/command.c.
4790 * Removed RESTART command for good. Updated the code and the
4793 * Rewrote parts of the task system. It is a bit simpler now.
4794 Removed unsued task priorities. The affected files are
4795 lib/silcutil/silctask.[ch].
4797 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Moved the USERS printing from the library to the application.
4800 Affected files lib/silcclient/command.c and silc/client_ops.c.
4802 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4806 * Added channel key re-key support. The re-key is perfomed
4807 only by the router and is done once in an hour. Added `rekey'
4808 field to the SilcChannelEntry in the server. Affected files
4809 silcd/server.c and silcd/idlist.h.
4811 * Added silc_task_unregister_by_context into the file
4812 lib/silcutil/silctask.[ch].
4814 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Added SILC_UMODE_GONE mode to indicate when the client is not
4817 present in the SILC network. Added also support to the local
4818 command AWAY that will set this mode. Added support of showing
4819 "xxx is gone" in WHOIS command. The USERS command shows the
4820 gone status as well.
4822 * Fixed setting server and router operator privileges in the
4823 server's UMODE command. Affected file silcd/command.c.
4825 * Merged the SKE KE1 and KE2 payloads into one payload. The
4826 new KE payload is equivalent to the old KE2 payload.
4828 Cleaned up the SKE Start Payload parsing. It now uses the
4829 simple buffer unformatting to do the parsing. A lot faster
4832 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4833 to the SKE that is used to indicate whether both of the SKE
4834 parties should perform authentication. By default only the
4835 responder performs authentication. By setting this flag also
4836 the initiator must do authentication. By default it is unset
4837 since in normal SKE case, client to server connection, only
4838 the responder should do authentication. When doing SKE between
4839 two clients both should perform authentication. Updated the
4840 code and the protocol specs.
4842 * A little fix to IDENTIFY command in the server. Search the
4843 client first by hash not nickname. Affected file is
4846 * Fixed the silc_client_close_connection to support closing
4847 the client to client connections wihtout deleting too much
4848 data. Affected file lib/silcclient/client.c.
4850 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4851 are received if protocol used to be active but is not anymore
4852 the application would crash due to NULL pointer dereference.
4853 Affected files silcd/server.c and lib/silcclient/client.c.
4855 * Added `hash' field to the SilcClientConnection to include
4856 the hash function negotiated in the SKE protocol.
4858 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4859 to set the channel founder authentication data. A client can
4860 claim the founder rights later by providing the authentication
4861 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4862 This way the channel founder can regain the channel founder
4863 privileges even it is left the channel. This works only on
4864 local server and the client must be connected to the same
4865 server to be able to regain the founder rights. Updated the
4866 protocol specs accordingly.
4868 Added support to the CMODE command in the client to set the
4869 founder auth data. Read the README to see how to set it.
4871 Added support to the CUMODE command to claim the founder
4872 rights. Read the README to see how to do it.
4874 Added support for the founder authentication to the Channel
4875 Entry in the server. Affected file silcd/idlist.h.
4877 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4878 server's CMODE command. Affected file silcd/command.c.
4880 * Added the following new functions into lib/silccore/silcauth.[ch]:
4881 silc_auth_get_method and silc_auth_get_data.
4883 * The server now saves the remote hosts public key to the
4884 SilcIDListData pointer. Affected file silcd/protocol.c.
4886 * The normal server now does not remove the channel entry from
4887 the cache if the founder authentication data is set. It used
4888 to remove it if the founder was the last one on the channel on
4889 the server and left the channel. The auth data is saved and
4890 if the channel is re-joined later the old entry is used with
4891 the old auth data. Affected files silcd/command_reply.c and
4894 * Removed the `pkcs' field from the SilcIDListData structure
4895 in the server; it is not used. Affected file silcd/idlist.h.
4897 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Fixed packet processing on slow links. Partial packets were
4900 never re-processed because the incoming data buffer was cleared
4901 by the application. Application must not directly clear the
4902 sock->inbuf, the packet processing routines handle it. Fixed
4903 this in client library and in server.
4905 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4907 * Fixed the WHOIS and IDENTIFY send reply function to really
4908 check whether to send list or just one entry. Affected file
4911 * Cleaned up the LEAVE command's channel key distribution. The
4912 affected file silcd/command.c.
4914 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4915 can enforce the channel mode as well. In that case the ID
4916 includes the ID of the server. The code now enforces the
4917 mode change if the router have different mode than the server.
4919 * The notify client operation with CMODE_CHANGE notify can now
4920 return NULL client_entry pointer if the CMODE was not changed
4921 by client. Application must check for this.
4923 * Added <Server ID> argument to INFO command to support server
4924 info fetching by Server ID.
4926 * Added silc_server_announce_get_channel_users to get assembled
4927 packets of channel users of the specified channel. Affected
4928 file silcd/server.[ch].
4930 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4931 was freed underneath the ID Cache.
4933 * Re-announce clients when the server received CHANNEL_CHANGE
4934 notify from the router. Affected file silcd/packet_send.c.
4936 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4938 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4939 crashed since it did not handle the fact that there is no cipher
4940 called "3" and didn't check the error condition. Now fixed.
4942 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4943 flag. It can be used to send message requests.
4945 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4947 * Implemented the RESTART command in the client.
4949 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4950 notice type messages. Added notice printing to the user
4953 * The channel keys are not re-generated if the channel's mode
4954 is PRIVKEY, ie private key on the channel exists. Affected
4955 files silcd/server.c and silcd/command.c.
4957 * Fixed a little bug in channel message delivery when channel
4958 private keys are set in the server. Affected file is
4959 silcd/packet_send.c.
4961 * Changed the setting on channel->on_channel = TRUE from the
4962 silc_client_save_channel_key to the JOIN command reply. The
4963 key payload is not received if the private channel key is set.
4964 Affected file lib/silcclient/command_reply.c and the
4965 lib/silcclient/client_channel.c.
4967 * When the CMODE_CHANGE notify is sent and the channel private
4968 key mode is removed the channel key must be re-generated in
4969 other cells as well. Added this support for the router in the
4970 silcd/packet_receive.c.
4972 * Added new local command NOTICE to send notice message on
4973 channel. Affected file silc/local_command.[ch].
4975 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4977 * Added new local command ME to the client. It is used to send
4978 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4979 some action. Affected file silc/local_command.[ch].
4981 * Changed channel_message and private_message client operations
4982 to deliver the message flags to the application. Added also
4983 the `flags' arguments to the silc_client_send_channel_message
4984 and silc_client_send_private_message functions. Affected file
4987 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Redefined the Private Message Payload to support private message
4990 keys and to support the new private message flags. Updated
4991 the protocol specs. Flags makes it possible to have for example
4992 CTCP style messages.
4994 * Added new type SilcPrivateMessagePayload and defined an API
4995 for it in the lib/silcclient/silcprivate.[ch].
4997 * Tested private message private keys successfully. Tested the
4998 private message key set, unset and list commands with the new
5001 * Redefined the Channel Message Payload to include the channel
5002 message flags (equal with private message flags) to support
5003 for example CTCP style messages.
5005 * Defined some of the message (for channel and private message)
5006 flags. Updated the protocol specs and added the flags to the
5007 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5009 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Added SilcKeyAgreementStatus type to the key agreement routines
5012 to indicate the current status and error if one occured.
5013 The status types are defined in the lib/silcclient/silcapi.h.
5015 * Added new local command KEY that is used to set and unset private
5016 keys for channels, set and unset private keys for private messages
5017 with remote clients and to send key agreement requests and
5018 negotiate the key agreement protocol with remote client. The
5019 key agreement is supported only to negotiate private message keys,
5020 it currently cannot be used to negotiate private keys for channels,
5021 as it is not convenient for that purpose.
5023 * Fixed a minor pending callback setting bug in the function
5024 silc_client_get_client_by_id_resolve, now the function works.
5025 Affected file lib/silcclient/idlist.c.
5027 * Added function silc_net_get_local_port to get local bound
5028 port by socket. Added to lib/silcutil/silcnet.[ch].
5030 * Added `sockets' and `sockets_count' fields to the SilcClient
5031 object. They hold the sockets of the listenning sockets in
5032 the client. Listenning sockets may be for example the key
5033 agreement server. Affected file lib/silcclient/client.[ch].
5034 Added functions the silc_client_add_socket and the
5035 silc_client_del_socket. They are exported to the application
5038 * Added ~./silc/clientkeys to support other client's public keys.
5040 * Renamed verify_server_key client operation to verify_public_key
5041 and added one argument to indicate the type of the connection
5042 (server, client etc.).
5044 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Added silc_server_connection_auth_request to handle the
5047 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5048 silcd/packet_receive.[ch].
5050 * Added silc_server_send_connection_auth_request into the
5051 silcd/packet_send.c to send the connection auth request packet.
5053 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5056 * Fixed the public key authentication in responder side in the
5057 server. The `auth_data' pointer includes the SilcPublicKey
5058 not the path to the public key. Affected file silcd/protocol.c.
5060 * Implemented the public key authentication in the initiator side
5061 in the server. Affected file silcd/protocol.c.
5063 * Removed the [RedirectClient] config section from the server
5064 configuration. Is not needed and I don't want to implement it.
5066 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5068 * Cleaned up the CMODE command in the server. It now works
5069 correctly and supports all the modes defined in the protocol.
5070 Affected file is silcd/command.c.
5072 * Added `hmac_name' field to the SilcChannelEntry in the server
5073 to hold the default HMAC of the channel. It can be set when
5074 creating the channel (with JOIN command). Affected files
5077 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5078 type to indicate the change of the current cipher and hmac
5079 on the channel. Client can safely ignore the <cipher> argument
5080 (if it chooses to do so) since the CHANNEL_KEY packet will
5081 force the channel key change anyway. The <hmac> argument is
5082 important since the client is responsible of setting the new
5083 HMAC and the hmac key into use.
5085 * Fixed the CMODE command in the client library as well.
5087 * Tested CMODE command in router environment successfully.
5089 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5091 * Show the version of the remote client (or server) when connecting
5092 to the server. It is logged to the log file. Affected file
5093 is silcd/protocol.c.
5095 * Fixed the KILLED notify handling in the client library. The
5096 client must be removed from all channels when receiving the
5099 Also, do not remove the client entry when giving the KILL
5100 command but when the KILLED notify is received.
5102 * Removed silc_idlist_find_client_by_nickname from the server.
5103 Not needed anymore. Affected files silcd/idlist.[ch].
5105 * Implemented the CHANNEL_CHANGE notify type handling to the
5106 server. Affected file silcd/server.c.
5110 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Added silc_server_send_notify_invite to send the INVITE
5113 notify between routers.
5115 * Implemented the INVITE command correctly to the server.
5117 * Implemented the INVITE notify type handling in the server.
5119 * Implemented the INVITE command to the client library and on the
5122 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Added function silc_server_get_client_resolve to find the
5125 client entry by ID from all ID lists and then resolve it
5126 (using WHOIS) if it cannot be found. Affected file is
5129 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Implemented the BAN command to the client library.
5133 * The JOIN command in the server now checks the invite list
5136 * Changed the silc_command_reply_payload_encode_va and the
5137 silc_command_payload_encode_va to support that if argument is
5138 NULL it ignores and checks the next argument. Affected file
5139 lib/silccore/silccommand.c.
5141 * Added silc_server_send_notify_ban to send the BAN notify
5142 type between routers.
5144 * Chaned the silc_notify_payload_encode to support that if
5145 argument is NULL it ignores and checks the next argument.
5146 Affected file lib/silccore/silcnotify.c.
5148 * Tested ban lists in router environment successfully.
5150 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5152 * Implemented BAN command to the server, in silcd/command.[ch].
5154 * Removed the BAN and INVITE_LIST modes from the CMODE command
5157 * Added function silc_string_match to regex match two strings.
5158 Affected files lib/silcutil/silcutil.[ch].
5160 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5162 * Redefined parts of the SilcChannelEntry in the server to support
5163 the new ban and invite lists.
5165 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5167 * Redefined the INVITE command. The same command can be used to
5168 invite individuals to the channel but also to manage the invite
5169 list of the channel (to add to and remove from the invite list).
5170 Updated the protocol specs.
5172 * Added new command SILC_COMMAND_BAN that can be used to manage
5173 the ban list of the channel. Updated the protocol specs.
5175 * Removed the channel modes: the SILC_CMODE_BAN and the
5176 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5177 in the CMODE command. The equivalent features are now available
5178 using INVITE and BAN commands. Updated the protocol specs.
5180 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5181 in the network about change in the current ban list. The notify
5182 type is not used by the client.
5184 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5185 support the invite lists.
5187 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Added new function silc_string_regexify that converts string
5190 including wildcard characters into regex string that can
5191 be used by the GNU regex library. Added into the file
5192 lib/silcutil/silcutil.[ch].
5194 Added silc_string_regex_combine to combine to regex strings
5195 into one so that they can be used as one regex string by
5196 the GNU regex library. Added into the file
5197 lib/silcutil/silcutil.[ch].
5199 Added silc_string_regex_match to match two strings. It returns
5200 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5202 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Imported GNU regex to the soruce tree into lib/contrib.
5205 Fixed some compiler warning from the regex.c.
5207 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5209 * Fixed MOTD command in the server to work in router environment.
5211 * Fixed the MOTD command in the client library to support
5212 the server argument in the command.
5214 * Added `nickname_len' argument to the silc_idlist_add_client
5215 in the server, as the `nickname' argument may be binary data
5218 * Added silc_idlist_get_channels to return all channels from
5221 * Implemented LIST command to the server. Affected file is
5224 * Implemented the LIST command to the client library and on the
5227 * Added [<user count>] argument to the LIST command reply.
5228 With private channels the user count is not shown.
5230 * Updated TODO and README.
5232 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * The client entry's data.registered must be TRUE even with
5235 global client entry on global client list. The data.registered
5236 is used to check whether the client is anymore in the network,
5237 for example with WHOWAS command so it must be valid.
5239 * Fixed the WHOWAS command in the server. It now actually works
5240 in router environment. Added function into silcd/command_reply.c
5241 silc_server_command_reply_whowas_save.
5243 * Added silc_idlist_purge function to the silcd/idlist.c
5244 to periodically purge the ID Cache.
5246 * Fixed INFO command in the server. It works now in router
5247 environment. Added <server name> argument to the INFO command
5248 reply. Updated the protocol specs.
5250 * Fixed minor bug in silc_idcache_purge to not purge if the
5251 expire value is zero.
5253 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5254 they were buggy because of the WHOWAS information.
5256 * Fixed local command MSG to handle the async resolving of
5257 the remote client properly. It used to fail the first MSG.
5258 Affected file silc/local_command.c.
5260 * Added `data_len' field to SilcIDCache context.
5262 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Update TODO. Todo in commands in the server.
5266 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5268 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5269 used by routers as broadcast packet to inform other routers
5270 about the changed user mode.
5272 Implemented the notify handling in the server. Affected file is
5273 silcd/packet_receive.c. Added the function
5274 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5276 * Added new generic Channel Payload and deprecated the New Channel
5277 Payload. The New Channel Payload is now the generic Channel
5280 * Added new argument `mode' to the silc_server_send_new_channel
5281 as it is required in the Channel Payload now.
5283 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5284 and created a new and real SilChannelPayload to represent the
5285 new generic Channel Payload. Implemented the encode/decode
5286 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5288 * Added silc_server_get_client_channel_list to return the list
5289 of channels the client has joined for WHOIS command reply.
5290 Affected file silcd/server.[ch].
5292 * Implemented the channel list sending in the WHOIS command reply
5293 in server and in the client.
5295 Implemented the channel list displaying on the user interface
5296 as well. Affected file silc/client_ops.c.
5298 * Added silc_channel_payload_parse_list to parse list of Channel
5299 Payloads. It returns SilcDList list of SilcChannelPayloads.
5300 Client for example can use this function to parse the list of
5301 channels it receives in the WHOIS command reply. The caller
5302 must free the list by calling silc_channel_payload_list_free.
5303 Affected files lib/silccore/silcchannel.[ch].
5305 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5307 * Added one new argument <user mode> to the WHOIS command reply
5308 to return the mode of the user in SILC. Updated the protocol
5311 Implemented it to the server and client.
5313 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5315 * Fixed the mode printing on the user interface on joining.
5316 Affected file silc/client_ops.c.
5318 * Implemented the UMODE command and user modes in general to the
5319 client library and to the user interface.
5321 * Implemented the UMODE command to the server.
5323 * The server now sends UNKNOWN_COMMAND error status if client sends
5324 unknown command. Affected file silcd/command.c.
5326 * All server commands now handle the command identifier the right
5327 way when sending the command reply to the client. The client can
5328 use to identify the command replies with the identifier.
5330 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5332 * Added silc_server_get_client_route to resolve the route to
5333 the client indicated by the client ID. Affected file is
5336 * Added silc_server_relay_packet as general function to relay
5337 packet to arbitrary destination. This deprecates functions
5338 like _send_private_message_key, _relay_notify etc. Affected
5339 file is silcd/packet_send.[ch].
5341 Removed silc_server_send_key_agreement,
5342 silc_server_send_private_message_key and
5343 silc_server_packet_relay_notify functions from the file
5344 silcd/packet_send.[ch].
5348 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5349 server. Affected file silcd/packet_receive.[ch].
5351 * Implemented the KILL command to the client. Implemented the
5352 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5353 Affected files lib/silcclient/command[_reply].c and
5354 lib/silcclient/client_notify.c. Implemented the KILL notify
5355 printing in the user inteface.
5357 * Fixed a lot silc_parse_nick memory leaks from the client
5358 library in the file lib/silcclient/command.c.
5360 * Changed the silc_server_send_notify_on_channels's `sender'
5361 argument from SilcSocketConnection to SilcClientEntry to
5362 check the sender as entry and not as connection object and not
5363 to send to the client provided as argument. The affected file
5364 is silcd/packet_send.[ch].
5366 * The notify packets that are destined directly to the client used
5367 to not to be processed by the server. Now changed that and the
5368 server processes all notify packets. After relaying the packet
5369 to the client the notify packet is processed in the server.
5371 * The silc_server_free_client_data now checks whether there is
5372 pending outgoing traffic for the client and purges the data to
5373 the network before removing the client entry.
5375 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5377 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5378 an client is killed from the SILC Network. Updated the protocol
5381 Added new function silc_server_send_notify_killed to the
5382 silcd/packet_send.[ch].
5384 * Added function silc_server_packet_relay_notify to relay notify
5385 packets that are destined directly to a client. In this case
5386 the server does not process the notify packets but merely relays
5387 it to the client. Affected file silcd/packet_send.[ch].
5389 Added also silc_server_packet_process_relay_notify to check
5390 whereto relay the notify. Affected file is
5391 silcd/packet_receive.[ch].
5393 * Implemented the KILL command to the server.
5397 * Added the backup schema desgined last fall to the protocol
5398 specs for everyone to see. The specification is in the
5399 *-spec-xx.txt draft and the packet type definitions for the
5400 backup routers is in *-pp-xx.txt draft. Thusly, added also
5401 new packet type SILC_PACKET_CELL_ROUTERS.
5403 * A big security problem in the implementation discovered. The
5404 signoff of an client did not cause new channel key generation
5405 which it of course should've done. The channel keys must be
5406 always re-generated when client leaves (or signoffs) the channel.
5407 The silc_server_remove_from_channels funtion now handles
5408 the channel key re-generation.
5410 * Added `sender' argument to the silc_server_send_notify_on_channels
5411 to not to send the client provided as argument. Affected file
5412 silcd/packet_send.[ch].
5414 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5416 * Implemented OPER and SILCOPER commands into the server and
5419 * Added silc_auth_verify and silc_auth_verify_data to verify
5420 the authentication directly from the authentication payload.
5421 It supports verifying both passphrase and public key based
5422 authentication. Affected file lib/silccore/silcauth.[ch].
5424 * Added `hash' field to the SilcIDListData structure. It is the
5425 hash negotiated in the SKE protocol. Affected file is
5428 * Slight redesigning of the SilcAuthPayload handling routines.
5429 Do not send SilcPKCS but SilcPublicKey as argument.
5431 * Implemented the public key authentication support to the
5432 serverconfig. The public key is loaded from the provided path
5433 and saved as authentication data to void * pointer. Thus,
5434 changed the unsigned char *auth_data to void *auth_data;
5436 * Fixed SHUTDOWN command to send the reply before the server
5437 is shutdown. :) Affected file silcd/command.c.
5439 * Fixed fatal bug in CONNECT command. The hostname was invalid
5440 memory and server crashed. Affected file silcd/command.c.
5442 * Fixed fatal bug in CLOSE command. The server_entry became
5443 invalid but was referenced later in the command. Affected file
5446 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5448 * Fixed fatal bug in failure packet handling. Server ignored
5449 the failure and thus crashed when it came.
5453 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5455 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5456 that the command may be executed only once in (about) 2 seconds.
5457 The old SILC_CF_LAG flag is same but allows command bursts up
5458 to five before limiting.
5460 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5461 server code. Various commands now includes the CF_LAG_STRICT
5462 flag to disallow any kind of miss-use of the command.
5464 * Fixed the silc_buffer_unformat to not to allocate any data
5465 if the length of the data is zero. It used to allocate the
5466 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5468 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Changed the format of AdminConnection configuration section
5471 in the server. Added username of the admin to the format.
5472 Affected files silcd/serverconfig.[ch].
5474 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5475 to return admin configuration data by host, username and/or
5478 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5480 * Implemented WHOWAS command to the server. Added the functions:
5482 silc_server_command_whowas_parse,
5483 silc_server_command_whowas_send_reply,
5484 silc_server_command_whowas_from_client and
5485 silc_server_command_whowas_from_server
5487 * Added <Client ID> argument to the WHOWAS command reply. Updated
5488 the protocol specs accordingly.
5490 * Implemented WHOWAS command and command_reply to the client
5493 Implemented the WHOWAS printing on the user interface.
5495 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5497 * Added new argument to the WHOWAS command reply, the real name.
5498 It is an optional argument. Updated the protocol specs.
5500 * Added SilcIDCacheDestructor callback that is registered when
5501 the SilcIDCache is allocated. The callback is called when
5502 an cache entry in the ID Cache expires, or is purged from the
5503 cache. Added into lib/silccore/idcache.[ch].
5505 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5506 to destruct the client entries when the cache entry expires.
5507 Other ID Cache's in server and in the client library ignores
5510 * If the ID Cache entry's `expire' field is zero then the entry
5511 never expires. Added boolean `expire' argument to the
5512 silc_idcache_add function in the lib/silccore/idcache.[ch].
5513 If it is TRUE the default expiry value is used.
5515 * Added silc_server_free_client_data_timeout that is registered
5516 when client disconnects. By default for 5 minutes we preserve
5517 the client entry for history - for WHOWAS command.
5519 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5521 * Added support to the server to enforce that commands are not
5522 executed more than once in 2 seconds. If server receives
5523 commands from client more frequently, timeout is registered
5524 to process the commands. Affected file silcd/command.c.
5525 Added new function silc_server_command_process_timeout.
5527 * Changed NICK_NOTIFY handling in client library to check that
5528 if the client's nickname was changed, so there is no need to
5529 resolve anything from the server.
5531 * Removed error printing from the WHOIS and IDENTIFY commands.
5532 If error occurs then it is ignored silently in the client library.
5533 The application, however, may map the received error to
5534 human readable error string. The application currently maps
5535 the NO_SUCH_NICKNAME error to string.
5537 * Made the command status message public to the application. Moved
5538 them from lib/silcclient/command_reply.c to
5539 lib/silcclient/command_reply.h. The application can map the
5540 received command status to the string with the
5541 silc_client_command_status_message function.
5543 * Added check to the server to check that client's ID is same
5544 as the Source ID in the packet the client sent. They must
5547 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5549 * Added dist-bzip hook to the Makefile.am to make bzip2
5550 compressed distributions.
5552 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5554 * Server now enforces the maximum length for the nickname and
5555 the channel as protocol specification dictates. 128 bytes for
5556 nickname and 256 bytes for channel name.
5558 * Moved the WHOIS printing to the application. The client libary
5559 does not print out the WHOIS information anymore, the application
5560 must do it. Renamed silc_client_command_reply_whois_print to
5561 the silc_client_command_reply_whois_save.
5563 The client's idle time is also sent to the application now, and
5564 the idle is shown on screen.
5566 * Added silc_client_command_reply_identify_save to save the
5567 received IDENTIFY entries.
5569 * Do not check for channel private keys in message sending and
5570 reception if the channel does not have the PRIVKEY mode set.
5571 Affected file lib/silclient/client_channel.c.
5573 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5575 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5576 just surfaced after chaning the JOIN procedure.
5578 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5580 * Added silc_client_get_clients_by_list to get client entries
5581 from Client ID list, that is returned for example by JOIN
5582 and USERS command replies. The application should use this
5583 function for example when JOIN command reply is received to
5584 resolve the clients already on the channel (library does not
5585 do that anymore as USERS command reply is not used in the JOIN
5586 procedure anymore). Affected files lib/silcclient/silcapi.h and
5587 lib/silcclient/idlist.c.
5589 * JOIN command reply and USERS command reply returns now SilcBuffer
5590 pointers instead of unsigned char pointers when returning
5591 the client list and mode list.
5593 * Added <Client ID> argument to the JOIN command reply, mainly
5594 for the server to identify for which client the command was
5595 originally sent. Updated protocol specs accordingly.
5597 * Added SilcDlist private_key pointer to the SilcChannelEntry
5598 in the client to support the channel private keys. Affected
5599 file is lib/silcclient/idlist.h.
5601 * Added SilcChannelPrivateKey argument to the function
5602 silc_client_send_channel_message so that application can choose
5603 to use specific private ke if it wants to. If it is not provided,
5604 the normal channel key is used, unless private keys are set.
5605 In this case the first (key that was added first) is used
5606 as the encryption key.
5608 * Implemented the support for channel private key handling.
5609 Implemented the following functions:
5611 silc_client_add_channel_private_key,
5612 silc_client_del_channel_private_keys,
5613 silc_client_del_channel_private_key,
5614 silc_client_list_channel_private_keys and
5615 silc_client_free_channel_private_keys
5617 Affected file lib/silcclient/client_channel.c.
5619 * Added the support for the private keys in the channel message
5620 sending and encryption and in the message reception and
5621 decryption. Affected funtions are
5622 silc_client_send_channel_message and silc_client_channel_message.
5624 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5626 * Added SKE's key verify callback to the client library's
5627 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5629 * Removed the statement that server (or router) must send USERS
5630 command reply when joining to the channel so that the client
5631 knows who are on the channel. Instead, the client list and
5632 client's mode list is now sent in the JOIN command reply to the
5633 client who joined channel. This is better solution.
5635 * Added function silc_server_get_users_on_channel and function
5636 silc_server_save_users_on_channel to the silcd/server.[ch].
5638 * Removed function silc_server_command_send_users from the
5641 * Do not show topic on the client library anymore. The topic is
5642 sent in the command reply notify to the application and the
5643 application must show the topic now.
5645 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5647 * Added client searching by nickname hash into the IDENTIFY and
5648 WHOIS commands in the server as they were clearly missing from
5649 them. Affected file is silcd/command.c.
5651 * Fixed a bug in private message receiving in the client library.
5652 The remote ID was freed and it wasn't supposed, now it is
5655 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5657 * Minor fix to the channel payload; allocate the data area, as it
5658 needs to be of specific length.
5660 * If the key agreement port is zero then the operating
5661 system will define the bound port. Affected files are
5662 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5664 * Added new function silc_channel_payload_decrypt into the file
5665 lib/silccore/silcchannel.[ch].
5667 * Moved the channel message etc, check from silc_packet_decrypt
5668 to applications. The library calls now a generic
5669 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5670 when the packet is either normal or special. This was done to
5671 allow more wide range of checking that was not allowed when
5672 the code was in library. Now applications can do virtually any
5673 checks to the packet and return to the library the decision how
5674 the packet should be processed. Affected files are
5675 lib/silccore/silcpacket.[ch].
5677 Added silc_server_packet_decrypt_check to the server and
5678 silc_client_packet_decrypt_check to the client library.
5680 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5681 to send with specified source and destination information.
5683 * Channel message delivery between routers was broken after the
5684 channel key distribution was fixed earlier. The channel key
5685 was used be to distributed to other routers as well which is not
5686 allowed by the protocol. Now this is fixed and channel keys
5687 really are cell specific and the channel message delivery between
5688 routers comply with the protocol specification.
5690 * Fixed various commands in server to check also the global list
5691 for the channel entry and not just the local list. The affected
5692 file silcd/command.c.
5694 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5696 * Added assert()s to buffer formatting and unformatting routines
5697 to assert (if --enable-debug) when error occurs. Affected
5698 file: lib/silcutil/silcbuffmt.c.
5700 * Changed to auto-reconnect to check whether the remote host is
5701 router and register the re-connect timeout if it is. It used
5702 to check that whether we are normal server, but router must do
5703 auto-reconnect with another router as well. Affected file
5706 * Removed the [<key len>] option from CMODE command as the cipher
5707 name decides the key length, nowadays. See the defined ciphers
5708 from the protocol specification.
5710 * Added [<hmac>] option to the CMODE command to define the HMAC
5711 for the channel. Added SILC_CMODE_HMAC channel mode.
5713 * Added [<hmac>] option for the JOIN command so that user can
5714 select which HMAC is used to compute the MACs of the channel
5717 * Added Hmac field to the Channel Message Payload. The integrity
5718 of plaintext channel messages are now protected by computing
5719 MAC of the message and attaching the MAC to the payload. The
5720 MAC is encrypted. Now, it is clear that this causes some
5721 overhead to the size of the packet but rationale for this is that
5722 now the receiver can verify whether the channel message decrypted
5723 correctly and also when private keys are set for the channel the
5724 receiver can decrypt the packet with several keys and check from
5725 the MAC which key decrypted the message correctly.
5727 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5728 lib/silccrypt/silccipher.[ch].
5730 * Added silc_hash_len to return the digest length into the
5731 lib/silcrypt/silchash.[ch].
5733 * Rewrote parts of Silc Channel Payload interface in the
5734 lib/silccore/silcchannel.[ch]. The encode function now also
5735 encrypts the packet and parse function decrypts it.
5737 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5739 * Fixed a minor formatting bug in the SKE's key material processing.
5740 It actually might have processed the keys wrong way resulting
5743 * Redefined the mandatory HMAC algorithms and added new algorithms.
5744 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5745 and hmac-md5 truncated to 96 bits. The mandatory is now
5746 hmac-sha1-96. Rest are optional (including the one that used
5747 to be mandatory). Rationale for this is that the truncated HMAC
5748 length is sufficient from security point of view and can actually
5749 make the attack against the HMAC harder. Also, the truncated
5750 HMAC causes less overhead to the packets. See the RFC2104 for
5753 * Added new [hmac] configuration section. The SKE used to use
5754 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5755 is of course wrong. The official names that must be proposed in
5756 the SKE are the ones defined in the protocol specification
5757 (hmac-sha1-96 for example). The user can configure any hmac
5758 using any hash function configured in the [hash] section. At
5759 least, the mandatory must be configured.
5761 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5763 * Added HMAC list to the SKE proposal list. It has now both
5764 hash algorithm list and HMAC list. This makes the protocol
5765 incompatible with previous versions. The SKE now seems to work
5766 the way it is supposed to work, for the first time actually.
5768 * Defined plain Hash algorithms to the protocol specification.
5771 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Implemented support for key agreement packets into the server.
5774 Added functions silc_server_key_agreement and
5775 silc_server_send_key_agreement. Other than these functions,
5776 server has nothing to do with this packet.
5778 * Added support for private message key packets into the server.
5779 Added functions silc_server_private_message_key and
5780 silc_server_send_private_message_key.
5784 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5785 called in the protocol's final callback instead in the END
5786 protocol state. This makes a little more sense and in the same
5787 time in client we can use the same protocol routines for normal
5788 key exchange and to key agreement packet handling as well.
5790 * Added to both client's and server's KE protocol context the
5791 SilcSKEKeyMaterial pointer to save the key material. We will
5792 bring the key material to the protocol's final callback by doing
5793 this. The final callback must free the key material.
5795 * Added SKE's packet_send callback into client's KE protocol
5796 context so that the caller can choose what packet sending function
5797 is used. This way we can use different packet sending when
5798 doing normal SKE when doing key agreement packet handling (in
5799 the key agreement packet handling we do not want to encrypt
5802 * Implemented the responder side of the key agreement routines
5803 in the client. The client can now bind to specified port and
5804 accept incoming key negotiation. The key material is passed
5805 to the application after the protocol is over.
5807 * Implemented the processing of incoming Key Agreement packet
5808 in the client. Added function silc_client_key_agreement to
5811 * Implemented the intiator side of the key agreement routines
5812 in the client. The client can now initiate key agreement with
5813 another remote client. The key material is passed to the
5814 application after the protocol is over.
5816 * Created client_keyagr.c to include all the key agreement
5819 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5820 SILC_TASK_CALLBACK except that it is not static.
5822 * Created client_notify.c and moved the Notify packet handling
5823 from the client.[ch] into that file.
5825 * Created client_prvmsg.c and moved all private message and
5826 private message key routines from the client.[ch] into that file.
5828 * Create client_channel.c and moved all channel message and
5829 channel private key routines from the client.[ch] into that file.
5831 * Changed silc_client_get_client_by_id_resolve to resolve with
5832 WHOIS command instead of IDENTIFY command, in the file
5833 lib/silclient/idlist.c.
5835 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5837 * Implemented the SKE's responder side to the Client library.
5839 * When FAILURE is received to the protocol do not trust it
5840 blindly. Register a timeout to wait whether the remote closes
5841 the connection as it should do it, only after that process the
5842 actual failure. This was changed to both client and server.
5844 * Added client_internal.h to include some of the structures
5845 there instead of client.h in lib/silcclient/.
5847 * Added function silc_task_unregister_by_callback to unregister
5848 timeouts by the callback function.
5850 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5852 * Some "Incomplete WHOIS info" errors has been appearing on the
5853 log files. Took away the entry->userinfo check from WHOIS
5854 reply sending. The entry->userinfo is now " " if client did not
5855 provide one. I thought this was fixed earlier but something
5856 is wrong still. Let's see if the error still appears.
5858 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5860 * Fixed a minor bug in the login when the channel key is
5861 re-generated in the server. It used to generate the key in
5862 wrong order and thus caused problems in the channel traffic.
5864 * Fixed a minor bug in channel key distsribution after
5865 KICK command. The key was not sent to the router even though
5868 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5870 * Added silc_ske_process_key_material_data as generic routine
5871 to process any key material as the SILC protocol dictates. The
5872 function is used by the actual SKE library but can be used by
5873 applications as well. This relates to the private message keys
5874 and the channel private keys since they must be processed the
5875 same way the normal SILC session keys. The protocol dictates
5876 this. Affected files: lib/silcske/silcske.[ch].
5878 Added also silc_ske_free_key_material to free the
5879 SilcSKEKeyMaterial structure.
5881 * Defined silc_cipher_set_key function to set the key for
5882 cipher without using the object's method function. The affected
5883 files: lib/silccrypt/silccipher.[ch].
5885 * Implemented silc silc_client_add_private_message_key,
5886 silc_client_add_private_message_key_ske,
5887 silc_client_del_private_message_key,
5888 silc_client_list_private_message_keys and
5889 silc_client_free_private_message_keys functions in the
5892 Added functions silc_client_send_private_message_key to send
5893 the Private Message Key payload and silc_client_private_message_key
5894 to handle incoming Private Message Key payload.
5896 * Added Cipher field to the Private Message Key payload to set
5897 the cipher to be used. If ignored, the default cipher defined
5898 in the SILC protocol (aes-256-cbc) is used.
5900 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5902 * Removed lib/silcclient/ops.h file.
5904 Redefined parts of the SILC Client Library API. Created new
5905 file silcapi.h that deprecates the ops.h file and defines the
5906 published Client Library API. Defined also private message key
5907 API and channel private key API into the file.
5909 This is the file that the application must include from the
5910 SILC Client Library. Other files need not be included by
5911 the application anymore.
5913 * Added new key_agreement client operation callback and also
5914 defined the Key Agreement library API for the application.
5916 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5918 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5919 is used by clients to request key negotiation between another
5920 client in the SILC network. If the negotiation is started it
5921 is performed using the SKE protocol. The result of the
5922 negotiation, the secret key material, can be used for example
5923 as private message key.
5925 Implemented the Key Agreement payload into the files
5926 lib/silccore/silauth.[ch].
5928 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Redefined ciphers for the SILC protocol. Added some new ciphers
5931 and defined the key lengths for the algorithms. Changed the
5932 code accordingly. The default key length is now 256 bits.
5934 * Fixed SKE key distribution function silc_ske_process_key_material
5935 when the key length is more than 128 bits. The default key
5936 length in SILC is now 256 bits.
5938 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5939 to indicate unsupported algorithm.
5941 * Renamed rijndael.c to aes.c and all functions as well.
5943 * Fixed a long standing channel key setting bug in client library.
5944 Weird that it has never surfaced before.
5946 * Fixed bug in channel deletion. If the entire channel is removed
5947 then it must also delete the references of the channel entry
5948 from the client's channel list as the client's channel entry and
5949 the channel's client entry share same memory.
5951 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5953 * Implemented CONNECT and SHUTDOWN commands in the client.
5955 * Implemented CLOSE command to the client.
5957 * Added the function silc_idlist_find_server_by_name into the
5958 files silcd/idlist.[ch].
5960 Added the function silc_idlist_find_server_by_conn into the
5961 files silcd/idlist.[ch].
5963 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5965 * DIE command was renamed to SHUTDOWN. Updated the both code
5968 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5969 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5971 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5974 * Added function silc_server_create_connection function to create
5975 connection to remote router. My server implementation actually
5976 does not allow router to connect to normal server (it expects
5977 that normal server always initiates the connection to the router)
5978 so the CONNECT command is only good for connecting to another
5981 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5983 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5984 or some other client was kicked from the channel.
5986 Implemented the handling of the notify type to both client
5989 Implemented silc_server_send_notify_kicked to send the KICKED
5990 notify. It is used to send it to the server's primary router.
5992 * Implemented the KICK command into server and client.
5994 * Added `query' argument to the silc_idlist_get_client function
5995 to indicate whether to query the client from server or not if
5998 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5999 to indicate that the client is not channel founder.
6003 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6005 * Removed the rng context from SilcPacketContext structure and
6006 changed that the packet routine uses the Global RNG API.
6008 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6010 * Added support for quit message that client can "leave" on the
6011 channel when it quits the SILC. It is ditributed inside the
6012 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6014 Added silc_server_free_client_data that will take the
6015 signoff message as argument.
6017 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6019 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6021 * Updated parts of the protocol specification to keep it up
6024 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6026 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6027 payloads in one packet.
6029 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6030 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6031 use now the new List flag.
6033 * Also deprecated the following packet types: REPLACE_ID,
6034 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6036 * Added list support for Notify packet in server.
6038 * Added silc_server_send_notify_channel_change to send the
6039 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6040 the silc_server_send_replace_id.
6042 * Added silc_server_send_notify_nick_change to send the
6043 NICK_CHANGE notify type. Deprecates the function
6044 silc_server_send_replace_id.
6046 * Added silc_server_send_notify_join to send the JOIN notify type.
6047 Deprecates the function silc_server_send_new_channel_user.
6049 * Added silc_server_send_notify_leave to send LEAVE notify type.
6050 Deprecates the function silc_server_send_remove_channel_user.
6052 * Added silc_server_send_notify_cmode and
6053 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6054 types. Deprecates the silc_server_send_set_mode function.
6056 * Added SERVER_SIGNOFF notify type to indicate that server has
6057 quit. This means that all clients on the channel from that
6058 server will drop. This can be also used when netsplit happens.
6060 Deprecated REMOVE_ID packet type since it is not needed anymore
6063 Added silc_server_send_notify_server_signoff to send the
6064 SERVER_SIGNOFF notify type. Deprecates the function
6065 silc_server_send_remove_id.
6067 Added also silc_server_send_notify_signoff to send the
6068 SIGNOFF notify type.
6070 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6071 SILC protocol from this day on. Changed the protocol
6072 specification as well.
6074 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6075 notify type. It is used between routers to notify about
6076 topic changes on a channel.
6078 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6081 * Partly updated the protocol specification to comply with the
6082 changes now made. It is still though a bit outdated.
6084 * The JOIN notify type now takes one extra argument <Channel ID>.
6085 The packet used to be destined to the channel but now the
6086 JOIN type may be sent as list thus it is impossible to
6087 destine it to any specific channel. By adding this argument
6088 it is again possible.
6090 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6092 * Added CREDITS file. The CHANGES and CREDITS file will appear
6093 in the distribution as well.
6095 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6097 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6098 types in the server's silcd/packet_receive.c.
6100 * Implemented CMODE and CUMODE to work in router environment.
6102 * Fixed minor encoding and decoding buglet from the
6103 lib/silccore/silcmode.c.
6105 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6108 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6110 * Changed all SilcConfigServer* and silc_config_server* to
6111 SilcServerConfig* and silc_server_config*, respectively.
6114 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6116 * Associated the ID (client or server ID) to the Authentication
6117 Payload to avoid any possibility of forging. Updated the
6118 protocol specification and the code accordingly.
6120 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6122 * The RSA key length is now save to the RsaKey context in the
6123 key generation process in lib/silccrypt/rsa.c. The key length
6124 is now used to figure out the maximum size of the block allowed
6125 to be encrypted/signed.
6127 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6128 is equivalent to the silc_mp_mp2bin but does not allocate any
6131 * Changed silc_mp_mp2bin API to take length argument. If it is
6132 non-zero then the buffer is allocated that large. If zero, then
6133 the size is approximated using silc_mp_sizeinbase, which however
6136 * Created Global RNG API which is global RNG that application can
6137 initialize. After initializing, any routine anywhere in the
6138 code (including library) can use RNG without allocating a new
6139 RNG object. This was done to allow this sort of use of the
6140 RNG in code that has no chance to allocate RNG object. All
6141 applications currently allocate this and many routines in the
6142 library use this. Affected file lib/silccrypt/silcrng.[ch].
6144 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6145 it to use the Global RNG API.
6147 * Defined Authentication Payload into protocol specification that
6148 is used during SILC session to authenticate entities. It is
6149 used for example by client to authenticate itself to the server
6150 to obtain server operator privileges.
6152 Implemented this payload into the lib/silccore/silcauth.[ch].
6153 Implemented also routines for public key based authentication
6154 as the new protocol specification dictates.
6156 Moved definitions of different authentication methods from
6157 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6159 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6160 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6161 silc_pkcs_verify_with_hash functions into the file
6162 lib/silccrypt/silcpkcs.[ch].
6164 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6166 * The client entry's userinfo pointer must be always valid.
6167 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6168 will fail since it requires the userinfo. Now, the userinfo
6169 is allocated as "" if actual userinfo does not exist. Actually,
6170 it must exist and it is totally Ok to drop client connections
6171 that does not announce the userinfo. However, we will make
6172 this workaround for now.
6174 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6175 to return the remote port by socket.
6177 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6179 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6180 SILC_SERVER_PENDING_EXEC and added an new macro
6181 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6182 data or when error occurs while processing the pending command.
6184 Added new argument `destructor' into silc_server_command_pending
6185 and to the SilcServerCommandPending object. This destructor is
6186 now called after calling the pending callback or if error occurs
6187 immediately. If error occurs the actual pending callback won't
6188 be called at all - only the destructor. The destructor may be
6189 NULL if destructor is not needed.
6191 All this applies for client library code as well. Similar
6192 changes were made there as well for the pending commands.
6194 In the client, the application must now allocate the
6195 SilcClientCommandContext with the silc_client_command_alloc
6198 * Added reference counter to the SilcServerCommandContext. Added
6199 function silc_server_command_alloc and silc_server_command_dup
6202 Same type of functions added to the client library for the same
6205 * Removed the cmd_ident from IDListData away since it is now
6206 global for all connections. It is the command identifier used
6207 in command sending and with pending commands. The affected file
6210 * Added reference counter to the SilcSocketConnection objecet to
6211 indicate the usage count of the object. The object won't be
6212 freed untill the reference counter hits zero. Currently only
6213 server uses this, and client ignores it. The client must be
6214 set to use this too later. The affected files are
6215 lib/silccore/silcsockconn.[ch]. Added also the function
6216 silc_socket_dup to increase the reference counter.
6218 This was mainly added because it is possible that the socket
6219 is removed underneath of pending command or other async
6220 operation. Now it won't be free'd and proper DISCONNECTING
6221 flags, etc. can be set to avoid sending data to connection that
6222 is not valid anymore.
6224 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6225 the connection. After that it sets SILC_SET_DISCONNECTED.
6226 It is, however, possible that the socket data is not still freed.
6227 The silc_server_packet_process now checks that data is not
6228 read or written to connection that is DISCONNECTED. The socket
6229 get's freed when the reference counter hits zero.
6231 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6233 * Changed the client operation API: channel_message operation's
6234 `sender' is now the client entry of the sender, not the nickname
6235 and the `channel' is the channel entry, not the channel name.
6237 In the private_message operation the `sender' is now also the
6238 client entry of the sender not the nickname.
6240 Affected file is lib/silcclient/ops.h and all applications
6241 using the client operations.
6243 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6245 * Moved the calling of ops->connect() from connect_to_server_final
6246 into receive_new_id functin since that is the point when the
6247 client is actually allowed to send traffic to network. The
6248 affected file is lib/silcclient/client.c.
6250 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6252 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6253 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6254 (if needs broadcasting) instead of broadcasting the packets one
6255 by one which would make a burst in the network traffic.
6257 * Added `broadcast' argument to the functions in silcd/server.[ch]
6258 silc_server_create_new_channel[_with_id] to indicate whether
6259 to send New Channel packet to primary router.
6261 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6263 * Added new function into the silcd/server.[ch] files:
6264 silc_server_create_new_channel_with_id to create new channel with
6265 already existing Channel ID.
6267 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6268 lib/silccore/silcpacket.h. This packet is used t send list of
6269 Set Mode payloads inside one packet. Server uses this to set
6270 the modes for the channels and clients on those channels, that it
6271 announced to the router when it connected to it. The protocol
6272 specification has been updated accordingly.
6274 * The silc_server_new_channel did not handle the packet coming
6275 from normal server as it normally does not send that. However,
6276 when it announces its channels it does send it. Implemented
6277 the support for that.
6279 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6280 into the file lib/silccore/id.h.
6282 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6284 * Fixed memory leaks in the functions silc_idlist_del_client,
6285 silc_idlist_del_channel and silc_idlist_del_server in the file
6286 silcd/idlist.c. All of those leaked like a sieve.
6288 * Fixed some small memory leaks in the client's function
6289 silc_client_notify_by_server.
6291 * Added functions into silcd/server.c: silc_server_announce_clients,
6292 silc_server_announce_channels and silc_server_announce_server.
6293 These functions are used by normal and router server to announce
6294 to its primary router about clients, channels and servers (when
6295 router) that we own. This is done after we've connected to the
6298 These functions effectively implements the following packet types:
6299 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6300 and SILC_PACKET_NEW_ID_LIST.
6302 * Added new functions into the silcd/packet_receive.[ch]:
6303 silc_server_new_id_list, silc_server_new_channel_list and
6304 silc_server_new_channel_user_list to handle the incoming
6305 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6307 * Added support of changing Channel ID in the function
6308 silc_server_replace_id. If the server that announces a channel
6309 to the router already exists in the router (with same name but
6310 with different Channel ID), router is responsible to send
6311 Replace ID packet to the server and force the server to change
6312 the Channel ID to the one router has.
6314 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6315 client that the Channel ID has been changed by the router. The
6316 normal server sends this to the client. Client must start using
6317 the new Channel ID as the channel's ID.
6319 Implemented handling of this new type into lib/silcclient/client.c
6320 into the function silc_client_notify_by_server.
6322 * Added new function silc_idlist_replace_channel_id into the files
6323 silcd/idlist.[ch] to replace the Channel ID.
6325 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * Call silc_server_command_identify_check always when processing
6328 the IDENTIFY command in silcd/command.c
6330 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6332 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6333 send keepalive packets. The packet can be sent by clients,
6334 servers and routers.
6336 Added function silc_socket_set_heartbeat into the file
6337 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6338 If not set, the heartbeat is not performed. The actual
6339 heartbeat is implemented in the low level socket connection
6340 library. However, application is responsible of actually
6343 Added silc_server_send_heartbeat to send the actual heartbeat
6344 packet into silcd/packet_send.[ch]. Server now performs
6345 keepalive with all connections.
6347 * Added silc_task_get_first function into lib/silcutil/silctask.c
6348 to return the timeout task with shortest timeout. There was a bug
6349 in task unregistration that caused problems. TODO has been
6350 updated to include that task system must be rewritten.
6352 * The client library will now resolve the client information when
6353 receiving JOIN notify from server for client that we know but
6354 have incomplete information.
6356 * Rewrote parts of silc_server_remove_from_channels and
6357 silc_server_remove_from_one_channel as they did not remove the
6358 channel in some circumstances even though they should've.
6360 * Encryption problem encountered in server:
6362 The LEAVE command used to send the Channel Key packet to the
6363 router immediately after generating it. However, the code
6364 had earlier sent Remove Channel user packet but not immediately,
6365 ie. it was put to queue. The order of packets in the router
6366 was that Channel Key packet was first and Remove Channel User
6367 packet was second, even though they were encrypted in the
6368 reverse order. For this reason, MAC check failed. Now, this
6369 is fixed by not sending the Channel Key packet immediately but
6370 putting it to queue. However, this is more fundamental problem:
6371 packets that are in queue should actually not be encrypted
6372 because packets that are sent immediately gets encrypted
6373 actually with wrong IV (and thus MAC check fails). So, packets
6374 that are in queue should be encrypted when they are sent to
6375 the wire and not when they put to the queue.
6377 However, the problem is that the current system has not been
6378 designed to work that way. Instead, the packet is encrypted
6379 as soon as possible and left to the queue. The queue is then
6380 just purged into wire. There won't be any fixes for this
6381 any time soon. So, the current semantic for packet sending
6384 o If you send packet to remote host and do not force the send
6385 (the packet will be in queue) then all subsequent packets to the
6386 same remote host must also be put to the queue. Only after the
6387 queue has been purged is it safe again to force the packet
6390 o If you send all packets immediately then it safe to send
6391 any of subsequent packets through the queue, however, after
6392 the first packet is put to queue then any subsequent packets
6393 must also be put to the queue.
6395 Follow these rules and everything works fine.
6397 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6399 * Added new function silc_server_remove_clients_by_server to
6400 remove all client entries from ID list when the server connection
6401 is lost. In this case it is also important to invalidate all
6402 client entires as they hold the invalid server entry. This
6403 fixes fatal bug when server has lost connection and will reconnect
6406 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6408 * Made some sanity checks to silc_server_daemonise like to check
6409 whether the requested user and group actually exists.
6411 * Added sanity check to SKE's silc_ske_responder_finish to check
6412 that the public and private key actually is valid.
6414 * Invalidate the client's nickname when receiving Replace ID
6415 packet and the Client ID is being replaced. This means that the
6416 server will query the nickname if someone needs it (client)
6419 * Sort the ID Cache in client library when the ID Cache data
6420 has changed (needs sorting).
6422 * Do not allow for SILC client to create several connections to
6423 several servers. The client does not support windows right now
6424 and generating multiple connections causes weird behaviour.
6426 Irssi-silc client does support windows and can handle several
6427 connections without problems, see: www.irssi.org and SILC plugin.
6429 * Fixed some places where client was added to the IDList. The
6430 rule of thumb is following (in order to get everything right):
6431 If the client is directly connected local client then the
6432 `connection' argument must be set and `router' argument must be
6433 NULL to silc_idlist_add_client function. If the client is not
6434 directly connected client then the `router' argument must
6435 bet set and the `connection' argument must be NULL to the
6436 silc_idlist_add_client function.
6438 * The funtion silc_server_packet_send_local_channel actually did
6439 not check whether the client was locally connected or not. It
6440 does that now. Fixed a bug related to LEAVE command.
6442 * Fixed Remove Channel User payload parsing bug in server's
6443 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6445 * The server's silc_server_save_channel_key now checks also the
6446 global ID list for the channel as it might not be in the local
6447 list. Fixed a bug related to LEAVE command.
6449 * Is this the end of the [<unknown>] buglet that has been lurking
6450 around for a long time? A little for loop fix in server's
6451 silc_server_command_whois_parse that is used by both IDENTIFY
6452 and WHOIS command. At least, this was a clear bug and a cause
6453 of one type of [<unknown>] buglet.
6455 * WHOIS and IDENTIFY commands call the function
6456 silc_server_command_[whois/identify]_check function even if
6457 we are not router server.
6459 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6461 * Added --with-gmp configuration option. If set the GMP
6462 is always compiled in the SILC source tree. If not set then
6463 it is checked whether the system has the GMP3 installed. If
6464 it has then the GMP won't be compiled (the system's headers
6465 and library is used), if it doesn't have it then the GMP is
6466 compiled in the SILC source tree.
6468 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6470 * Changed RSA private exponent generation to what PKCS #1
6471 suggests. We try to find the smallest possible d by doing
6472 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6473 not security fix but optimization.
6475 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6477 * Added new config entry [Identity] to fork the server and run
6478 it as specific user and group. A patch from Bostik.
6480 * Imported Dotconf configuration library into lib/dotconf.
6481 This will be used to create the SILC configuration files later.
6482 It will appear in the distsribution after this commit.
6484 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6486 * A big code auditing weekend happening. Auditing code for
6487 obvious mistakes, bugs and errors. Also, removing any code
6490 Removed files for being obsolete:
6492 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6493 inline in the file lib/silcutil/silcbuffer.h)
6495 o lib/silcutil/silcbufutil.c (the header has inline versions)
6497 Changed code to fix possible error conditions:
6499 o The buffer formatting routines now check that the destination
6500 buffer really has enough space to add the data. This applies for
6501 both buffer formatting and unformatting
6502 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6503 unformatting was changed to accomodate following rules:
6504 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6505 sent to the function while XXX_*STRING will not allocate or copy
6506 the data into the buffer. Instead it sets the pointer from the
6507 buffer into the pointer sent as argument (XXX_*STRING used to
6508 require that the pointer must be allocated already). This change
6509 makes this whole thing a bit more consistent and more optimized
6510 (note that the data returned in the unformatting with XXX_*STRING
6511 must not be freed now). The routines return now -1 on error.
6513 o Tried to find all code that use buffer_format and buffer_unformat
6514 and added return value checking to prevent formatting and
6515 especially unformatting errors and possible subsequent fatal
6518 o Changed ske->x and ske->KEY to mallocated pointers in
6519 lib/silcske/silcske.h. Fixed possible data and memory leak.
6521 o Added return value checking to all *_parse* functions. Fixed
6522 many memory leaks as well.
6524 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6525 so that buffer overflows would not happen. All code now also
6526 checks the return value as it can fail.
6528 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6530 * Added reconnection support to server if the normal server looses
6531 its connection to the router (for example if router is rebooted).
6532 The server performs normal reconnection strategy implemented
6533 to the server. Affected file silcd/server.c.
6535 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6537 * Added new packet type SILC_PACKET_SET_MODE that is used to
6538 distribute the information about changed modes (for clients,
6539 channels and clients channel modes) to all routers in the
6540 network. Updated the protocol specification accordingly.
6542 Added functions into silcd/packet_send.c and
6543 silcd/packet_receive.c: silc_server_send_set_mode,
6544 silc_server_set_mode.
6546 Added new files silcmode.[ch] into lib/silccore that implements
6547 the encoding and decoding of Set Mode Payload. Added new type
6548 SilcSetModePayload. Moved the definitions of different modes
6549 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6551 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6553 * Oops, a little mistake in server's connection authentication
6554 protocol. The protocol is not ended with FAILURE but with
6555 SUCCESS if the authentication is Ok. :) Affected file is
6558 * Implemented NICK_CHANGE notify handling in server in the file
6559 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6560 the local clients on the channel. After the changing nickname
6561 in router environment snhould work and the [<unknown>] nickname
6562 should appear no more.
6564 The silc_server_replace_id function that receives the Replace ID
6565 payload now sends the NICK_CHANGE notify type also in the file
6566 silcd/packet_receive.c
6568 * Changed WHOIS and IDENTIFY command to support the maximum amount
6569 of arguments defined in protocol specs (3328 arguments). This
6570 fixed a bug that caused problems when there were more than three
6573 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6575 * Added extra parameter, command identifier, to the
6576 silc_client_send_command so that explicit command identifier
6579 Changed that ID list routines uses specific command identifier
6580 when sending WHOIS/IDENTIFY requests to the server so that they
6581 can be identified when the reply comes back.
6583 Affected files lib/silcclient/command.[ch],
6584 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6586 * Added `sender' argument to silc_server_packet_send_to_channel
6587 to indicaet the sender who originally sent the packet to us
6588 that we are now re-sending. Ignored if NULL. Affected file
6589 silcd/packet_send.[ch].
6591 * Added some server statistics support in silcd/server_internal.h
6592 SilcServerStatistics structure and around the server code. Also
6593 send some nice statistics information when client is connecting
6596 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6598 * Fixed channel ID decoding in server's JOIN command reply in
6599 silcd/command_reply.c
6601 * Fixed braodcasting of replace ID payload to not to send it if
6602 we are standalone server in silcd/packet_receive.c.
6604 * Fixed all channel message sending routines to not to send
6605 packets to clients that has router set, since they are routed
6606 separately in the same function earlier. Affects file
6607 silcd/packet_send.c and all channel packet sending functions.
6609 * In USERS reply, res_argv[i] are not allocated, the table
6610 is allocated. Thus changed that free the table, not its
6613 * In server's whois_check and identify_check if the client is
6614 locally connected do not send any WHOIS commands - they are not
6617 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6619 * Fixed some minor bugs in client when sending WHOIS command. The
6620 arguments was in wrong order.
6622 * Removed statis function add_to_channel from server in
6623 silcd/command.c that was previously used with the joining but
6626 * Tested USERS command in router environment successfully with two
6627 routers, two servers and two clients.
6629 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6631 * Reorganized the USERS command and command reply in client library
6632 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6633 When the command is given by user we register a pending command
6634 callback that will reprocess the command after the reply has been
6635 received from the server. When reprocessing the packet we then
6636 display the information. Thus, the USERS information is displayed
6637 now in the command callback instead of in the command reply
6638 callback. The processing of the command is same as previously
6639 when server has sent the command reply in the JOINing process.
6641 * Added to USERS command in silcd/command_reply.c to join the client,
6642 we didn't use to know about, to the channel after we've created
6643 a client entry for it. Also, for clienet we did know already still
6644 check whether it is on the channel or not and add it if not.
6646 * Removed silc_server_command_join_notify as the function and its
6649 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6651 * Changed the client's pending command handling to the same as the
6652 server's pending command handling. It is also now possible to
6653 execute command reply functions from other command reply
6654 function as the function callbacks for commands and command
6655 replies are one and same. The pending commands are not static
6656 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6657 in client connection context. Thus, pending commands are server
6658 connection specific as it is convenient.
6660 Changed the function silc_client_command_pending and
6661 silc_client_command_pending_del and added new function
6662 silc_client_command_pending_check. Removed the
6663 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6666 * Added cmd_ident, current command identifier, to the client
6667 connection context in lib/silcclient/client.h to keep track on
6668 command identifiers used in command sending. Client's command reply
6669 function handling now supports the mandatory command identifiers.
6671 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6672 funtions in client to fully support pending command callbacks.
6674 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6675 as one of the arguments to the application in the command reply
6678 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6679 before first releasing SILC but came back. Now it is removed again
6680 and should come back nomore. The FORWARDED flag was used only
6681 by the JOINing procedure by forwarding the command packet to router.
6682 Now, the JOINing procedure has been changed to more generic (due
6683 to various router environment issues) and FORWARDED is not needed
6684 anymore for anything. The protocol specification is yet to be
6687 Now, removed silc_server_packet_forward from server and the flag
6688 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6690 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6692 * Renamed NAMES command to USERS command. The NAMES was named that
6693 due to historical reasons. Now it is renamed. Also, rewrote
6694 parts of the USERS command. The nickname list is not sent anymore
6695 by the server. Only Client ID and mode lists are sent in the USERS
6696 command. Changed this also to the protocol specification.
6698 The client now resolves the names and stuff after it receives
6699 the USERS list from the server when joining to the channel.
6701 * WHOIS and IDENTIFY commands has been changed to support multiple
6702 Client ID's per command. One can now search for multiple users
6703 in the network by sending only one WHOIS or IDENTIFY command.
6704 Changed the code and the protocol specifications.
6706 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6707 uses silc_server_command_whois_parse to parse the request. */
6709 * If normal server, do not parse the WHOIS and IDENTIFY requests
6710 before sending it to the router. Saves some time.
6712 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6714 * Fixed JOIN command on client library. Wrong number of arguments
6715 used to crash the client.
6717 * Added silc_server_channel_has_global function to check whether
6718 channel has global users or not.
6720 * Added silc_server_channel_has_local function to check whether channel
6721 has locally connected clients on the channel.
6723 * The silc_server_remove_from_one_channel now checks whether the
6724 channel has global users or not after given client was removed from
6725 the channel. It also checks whether the channel has local clients
6726 on the channel anymore. If it does not have then the channel entry
6727 is removed as it is not needed anymore.
6729 * The silc_server_notify now checks on JOIN notify whether the joining
6730 client is one of locally connected or global. If it is global then
6731 the channel has now global users on the channel and that is marked
6732 to the channel entry. Also, it now saves the global client to
6733 global list who is joining and JOINs it to the channel. This is
6734 for normal server, that is.
6736 Changed silc_server_send_notify_on_channel,
6737 silc_server_packet_relay_to_channel and
6738 silc_server_packet_send_to_channel check if we are normal server
6739 and client has router set (ie. global client) do not send the
6740 message to that client, as it is already routed to our router.
6742 * Implemented LEAVE notify type handling in silc_server_notify
6745 * Tested LEAVE command in router environment successfully. Tested
6746 with two routers, two servers and two clients.
6750 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6752 * Implemented SIGNOFF notify type handling in silc_server_notify
6755 * silc_server_remove_id now removes the client entry from all channels
6756 it has joined and thusly sends SIGNOFF notify type.
6758 * Rewrote the NAMES list generation in server by removing two excess
6759 loops. The lists are created now inside one loop.
6761 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6763 * silc_server_remove_channel_user checks now also global list
6764 for channel and client.
6766 * silc_server_new_channel_user checks now both local and global
6767 list for channel and client. Fixed a bug in client id decoding.
6768 Used to decode wrong buffer.
6770 * silc_server_channel_message checks now both local and global
6771 list for channel entry.
6773 * Tested channel joining (hence JOIN) in router environment
6774 successfully. Tested with two routers, two servers and two
6777 * Tested channel message sending in router environment successfully.
6779 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6781 * Added silc_server_save_channel_key into server.[ch] to save the
6782 received channel key in Channel Key payload processing. It is
6783 also used in JOIN command reply handling.
6785 Equivalent function silc_client_save_channel_key added into
6786 client.[ch] into client library.
6788 * Changed JOIN command reply to send information whether the channel
6789 was created or not (is existing already) and the channel key
6790 payload. Changed protocol specs accordingly.
6792 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6793 the request was sent by ID and not by nickname. Crashed on
6796 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6798 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6799 now correctly save the received data.
6801 * silc_server_free_sock_user_data now notifies routers in the
6802 network about entities leaving the network.
6804 At the same time implemented functions silc_server_remove_id
6805 and silc_server_send_remove_id to receive and send REMOVE_ID
6806 packets. The packet is used to notify routers in the network
6807 about leaving entities. The ID removed will become invalid in
6810 * Added function silc_idlist_del_server into server. Removes and
6811 free's server entry from ID list.
6813 * silc_server_private_message function now checks, if we are router,
6814 that the destination ID really is valid ID, naturally.
6816 * In router when NEW_ID packet is received (for new client) the
6817 hash of the Client ID is saved in the ID Cache but the
6818 client->nickname is set to NULL, instead of putting the hash
6821 IDENTIFY command now also checks that client->nickname must be
6822 valid. If it is not if will request the data from the server who
6823 owns the client. Added new function
6824 silc_server_command_identify_check.
6826 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6827 to set the command to already allocated Command Payload.
6829 * Tested private message sending in router environment with two
6830 routers, two servers and two clients. Fixed minor bugs and now
6833 * Fixed segfault from client's NAMES command. Used to crash if
6836 * Forwarded packets must not be routed even if it is not destined
6837 to the receiver. Changed server code comply with this.
6839 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6841 * Added `require_reverse_mapping' boolean value to ServerParams
6842 structure. If TRUE (not default) the server will require that
6843 the connecting host has fully qualified domain name.
6845 If the reverse mapping is not required and hostname could not be
6846 found the IP address is used as hostname.
6848 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6850 * Implemented version string checking to both client and server.
6851 The check is incomplete currently due to the abnormal version
6852 strings used in development version of SILC.
6854 * Changed all command functions in server to use the new
6857 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6859 * Changed char *data to unsigned char *data in ID Cache system to
6860 support binary data as ID Cache data. Changed code to support
6861 binary data in lib/silccore/idcache.c.
6863 * Renamed silc_server_packet_relay_command_reply to
6864 silc_server_command_reply as it is normal packet receiving
6865 function. Rewrote the function to accept command replys for
6866 servers and not only for clients.
6868 * Mark remote router always as registered server if we are connecting
6869 to it. Otherwise, commands sent by the router to us are ignored.
6871 * All ID List find routines now returns the ID Cache Entry pointer
6872 as well if requested.
6874 * WHOIS command works now in router environment, tested with two
6875 routers, two servers and two clients.
6877 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6878 in router environment (as it is almost equivalent to WHOIS) but
6879 hasn't been tested thoroughly. Added new functions:
6881 silc_server_command_identify_parse
6882 silc_server_command_identify_send_reply
6883 silc_server_command_identify_from_client
6884 silc_server_command_identify_from_server
6886 * Disabled route cache adding because adding two different ID's with
6887 same IP replaces the old cache entry thus giving wrong route.
6888 The entry->router->connection is always the fastest route anyway
6889 so route cache may not be needed. Of course, new routes maybe
6890 established after receiving the ID when the entry->router->connection
6891 might not be anymore the most optimal.
6893 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6895 * Add route cache for received ID for fast routing.
6897 * Added silc_server_packet_route to route received packet on router
6898 that is not destined to us.
6900 * Renamed silc_server_get_route to silc_server_route_get.
6902 * Added id_string and id_string_len fields into SilcServer to
6903 include encoded ServerID for fast comparing without excess
6904 encoding of the ID's.
6906 * Cleaned up WHOIS command on server side. Added following static
6909 silc_server_command_whois_parse
6910 silc_server_command_whois_check
6911 silc_server_command_whois_send_reply
6912 silc_server_command_whois_from_client
6913 silc_server_command_whois_from_server
6915 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6916 arguments in command replies. All command functions should be
6917 updated to use this macro.
6919 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6921 * Minor typo fixes on command reply handling on server.
6923 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6925 * Added silc_server_command_add_to_channel internal routine to add
6926 the client to the channel after router has created the channel and
6927 sent command reply to the server.
6929 * Added generic silc_server_send_command to send any command from
6932 * Use static buffer with ID rendering instead of duplicating data.
6934 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6936 * Fixed a channel user mode bug when joining to a channel server gave
6937 everybody channel founder rights, oops.
6939 * We mark ourselves as the router of the incoming server connection
6940 if we are router ourselves. This way we can check in some packet
6941 sending functions whether it is locally connected server. For
6942 incoming router connections we put NULL.
6944 * For router sending packets locally means now always sending the
6945 packet cell wide; to local clients and local servers. For normal
6946 server sending packet locally means sending it to only local
6949 * Fixed the JOIN command to really work in router environment. If the
6950 channel is created it is always created by the router. Router is
6951 also responsible of making the initial joining to the channel,
6952 sending JOIN notify to the sending server and distributing
6953 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6954 does not exist server doesn't do anything else but forward the
6955 command to the router which performs everything.
6957 * Added silc_server_send_channel_key function to send the Channel Key
6960 * Added silc_server_create_channel_key to create new channel key. The
6961 channel key is now re-generated everytime someone joins or leaves
6962 a channel, as protocol dictates. Note: channel->key_len is the
6965 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6967 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6968 packet_receive.[ch] to separate packet sending and receiving
6969 routines. The server.[ch] now includes everything else including
6970 actual packet processing (writing and reading data) and other
6973 Renamed silc_server_private_message_send_internal to
6974 silc_server_send_private_message. The routine is still though
6975 used only to relay private messages as server does not send
6976 private messages itself.
6978 Renamed silc_server_new_channel to silc_server_create_new_channel
6979 and added new function sicl_server_new_channel that handles the
6980 incoming New Channel packet. Added also new sending function
6981 silc_server_send_new_channel to send New Channel Payload.
6983 * Added new function silc_server_notify to process incoming notify
6984 packet to the server/router. Server may then relay the notify
6985 to clients if needed.
6987 * Added new function silc_server_new_channel_user to process incoming
6988 New Channel User packet. Router will redistribute the packet and
6989 send JOIN notify to its local clients and locally connected servers
6990 if needed. Normal server will send JOIN notify to its local client
6991 on same channel when received this packet. Added also corresponding
6992 sending function silc_server_send_new_channel_user to sent the
6995 * Added boolean route argument to send_notif_to_channel and
6996 packet_send_to_channel functions to attempt to route the packet
6997 if it is TRUE and send only locally if it is FALSE.
6999 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7001 * silc_server_replace_id now broadcasts the received replace ID
7002 packet if it is not broadcast packet already. The router must
7003 broadcast to inform other routers about changed ID.
7005 * Added backpointer to server's router into SilcServer context in
7006 silcd/server_internal.h.
7008 * Fixed silc_server_packet_broadcast to send correct broadcast
7011 * The channel key is now distributed to the local client as soon
7012 as it is received from the router (in router environment) so that
7013 no other packet may be sent for the channel until client has
7016 * silc_server_remove_channel_user now broadcasts the received
7017 Remove Channel User packet if it is not broadcast packet already.
7018 The router must broadcast to inform other routers about removed
7021 * Added users field into SilcPacketContext that is a reference count
7022 of the context. One can increase the reference count by calling
7023 silc_packet_context_dup which is now changed to just increase the
7024 reference count instead of duplicating the data. The reference
7025 count is decresed by calling silc_packet_context_free that will
7026 free the data after the reference count hits zero.
7028 For now on the packet context and everything allocated into it
7029 (including the raw packet from network) must be freed by calling
7030 the new silc_packet_context_free function. Added also new function
7031 silc_packet_context_alloc that must be used now to allocate the
7032 context. This also means that if a routine is asynchronous from
7033 silc_[client/server]_packet_parse_type the packet context must
7034 be duplicated by calling silc_packet_context_dup. Otherwise it
7035 gets free'd after silc_[client/server]_packet_parse_type returns.
7036 Also, one must remember that if packet is duplicated then its
7037 reference count must be decresed by calling the free function as
7038 many times as it was duplicated.
7040 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7041 from both client and server.
7043 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7045 * Made joining to a channel working in router environment.
7047 * Cleaned up JOIN command on server side and create function
7048 silc_server_command_join_channel internal routine to make the
7051 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7053 * Changed silc_command_pending list to SilcDList. Also, added
7054 `ident' field to SilcServerCommandPending structure to identify
7055 the reply and to call correct callback.
7057 Added silc_server_command_pending_check function to replace the
7058 corresnponding macro. The silc_command_pending list is not
7061 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7062 to set identifier to previously allocated Command Payload. It
7063 is used to set identifier for command when resending Command
7066 * Added silc_command_payload_encode_payload to encode Command
7067 Payload buffer from SilcCommandPayload structure.
7069 * Added silc_argument_payload_encode_payload to encode Argument
7070 payload buffer from SilcArgumentPayload structure.
7072 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7074 * Changed WHOIS command to support router connection on server side.
7075 The whois request is always sent to router unless the server is
7076 standalone server. After server has received the reply from the
7077 router will it send the reply to the client.
7079 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7080 broadcast received broadcast packet. The function is used only
7081 by router. The broadcast packet is always sent to the router's
7084 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7085 render given ID to printable string, for log files for example.
7087 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7089 * Made basic router to router connections working. At least they
7090 can now connect to each other but nothing really works the way
7091 they are supposed - yet.
7093 * Added new initiator token to RouterConnection configuration
7094 file in silcd/serverconfig.[ch]. It is used to tell whether we
7095 are the initiator to the remote router or whether we'll expect
7096 the other end to connect.
7098 * Moved registering of listener task to silc_server_init, hence
7099 the server starts listenning as soon as it is run, even if it
7100 does not have connections to other routers. Let's see how well
7103 * Changed default connection retry timeouts for more suitable in
7106 * Removed cipher and such arguments from silc_idlist_add_client
7107 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7108 Added new function silc_idlist_add_data to add the keys and stuff
7111 * Added SilcIDListData structure and added it to SilcClientEntry
7112 and SilcServerEntry as their first field in the structure. This
7113 way we can explicitly cast the ID entries to the SilcIDListData
7114 structure and get common data for the entries. In past, we had
7115 to first check what type of connection it is and then cast it to
7116 correct ID entry type. Now, we can directly cast the opaque
7117 pointer to the SilcIDListData (no matter what ID entry it actually
7118 is) and get the data needed.
7120 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7122 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7123 in some circumstances even if threre were timeout tasks, though not
7124 IO tasks, but tasks anyway. Now fixed.
7126 * Defined SilcServerConnection structure to hold connection specific
7127 stuff about directly connected servers and routers. The definition
7128 is currently in silcd/server_internal.h. I thought about having
7129 a bit more important role fro this struct but for now it is used
7130 only when connecting to other server (or router actually).
7132 * Added connecting retry support in server when connecting to
7133 router(s). The retry feature implement exponential backoff
7134 algorithm. Also, added SilcServerParams structure to hold default
7135 parameters for server. For now, it include these retry settings
7136 and are hard coded. After server is moded to be as Silc Server
7137 Library this structure will be more important.
7139 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7141 * Changed client librarys channel->clients table to SilcList and
7142 changed code accordingly.
7144 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7146 * Changed client's channel table to SilcList and changed code
7147 accordingly. Also changed SilcChannelClientEntry to include back-
7148 pointer to the channel so that client entry can use that structure
7149 as list as well and we have fast cross-reference to the channel.
7150 This change dramatically decreased the complexity of channel
7151 handling with client entry and vice versa (removed one extra
7152 loop when searching for channel entry from many functions).
7154 * Changed server->sim from table to SilcDList and changed code
7157 * NAMES command can now be used from user interface. It will show
7158 the user list on the channel, neatly.
7160 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7161 Code now saves realname of the user if it becomes available.
7163 * Renamed configure.in to configure.in.pre and made ./prepare
7164 script to automatically add correct version string to
7165 configure.in which it creates from configure.in.pre.
7167 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7169 * NAMES command reply now shows users mode with the nickname when
7172 * Moved silc_client_ch[u]mode[_char] functions from
7173 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7174 place sucks, they are utility functions and should be in some
7177 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7179 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7182 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7186 * Added TRQ (efficient deque and list library) into lib/trq. This is
7187 a very good list library that is currently used in the SILC. Defined
7188 SilcList API over the library because I didn't like the API very
7189 much. See lib/trq/silclist.h for the API and examples of how to
7190 use the API. Fixed various places in the code to use the new
7191 SilcList API. The SilcList is meant for lists that has a structure
7192 already defined as a list. It is not suitable to add just some
7193 context to the list (in TRQ, the context is the list actually).
7195 So, I defined SilcDList that can be used for the purpose where
7196 predefined list structure does not exit. This can be used as
7197 such list. Now some context just can be added to the SilcDList.
7198 Currently this list is not used in the SILC just yet, though there
7199 are a lot places where this can replace dynamically allocated
7200 tables and I will fix these places, later, to use SilcDList.
7201 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7202 and use TRQ internally).
7204 Also fixed some annoying warning messages that the original TRQ
7205 code generated. Also minor changes to TRQ's Makefile.in.
7207 * Added support for querying by Client ID to both WHOIS and
7208 IDENTIFY commands into server, as required by the protocol.
7210 * Removed method function pointers from SilcBuffer structure. They
7211 weren't used to anything and just increased the context size for
7212 no good reason. This change also made silc_buffer_alloc and
7213 silc_buffer_free functions inline functions.
7215 * Disabled command flooding detection support until it's fixed so
7216 that it accepts commands in but does not execute them more than once
7219 * Added silc_net_localhost(), to return local hostname, into
7220 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7221 that must be initialized before calling silc_client_init.
7223 * Added new function: silc_server_send_notify_on_channels to send
7224 notify messages to all channels client has joined. It is assured
7225 that the message is sent only once per client.
7227 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7228 lib/silcutil/silcutil.[ch] as silc_format function. The new
7229 function is generic and is used by server as well, not only by
7230 the logging routines.
7232 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7233 the provided version string was not acceptable. Added new function:
7234 silc_ske_check_version into lib/silcske/silcske.h. The function
7235 must be implemented by the application (client or server) and it
7236 does not reside in the SKE library. The function checks the version
7237 string remote end sent.
7239 * Added back pointers (to opaque context and to SilcSocketConnection)
7240 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7242 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7243 duplicate packet context structure.
7245 * Changed `notify' client operation to send same arguments as client
7246 receives from server except for ID's. ID's are mapped to correct
7247 ID entry and that is returned. Also, if channel entry is not sent
7248 by server but the notify is for channel the channel entry is sent
7249 to application (otherwise application doesn't know that it is for
7250 channel (library gets it from packet's Destination ID)).
7252 * Added silc_client_remove_from_channels into client library to
7253 remove a client from all channels it has joined to. Used when
7254 received SIGNOFF notify from server. Added also new function
7255 silc_client_replace_from_channels to replace old ID entry with
7256 new ID entry on all channels. Used when received NICK_CHANGE
7259 * Fixed ID Cache list handling in silc_idlist_get_client in
7260 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7261 to get (or query) client by ID.
7263 * Updated TODO list.
7265 * Added connection authentication status message defined by the
7266 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7267 support for these into the code in client and server side.
7269 * Added generic function silc_client_send_command to send any command
7270 with variable argument list. Application should use this function
7271 to send commands if the command functions provided by the library
7272 does not suite for the application's user interface needs.
7274 * Added new `failure' client operation. Application is notified about
7275 received failure packet if client is executing a protocol. In this
7276 case the protocol's execution has failed.
7278 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7279 is required by the protocol.
7281 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7282 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7285 * Added status flag to SilcSKE object to indicate realtime status
7286 of the SKE protocol.
7288 * Application receives now exactly same command reply arguments as
7289 the library receives from server. However, if ID is received the
7290 corresponding ID entry is returned to the application (eg. Client
7291 ID is mapped to correct SilcClientEntry entry and that is returned).
7292 Changed command_reply client operation due to this change.
7294 * Changed all ID's in commands and in command replys as ID Payloads.
7295 Change affected both client and server side codes.
7297 All ID's sent in SILC network (with execption of ID's in SILC
7298 Packet header) are sent in ID Payload to support variable length
7301 * Server now notifies nick changes and notifies all clients on
7302 the channels about the new nickname (about the new Client ID,
7305 * Implemented CMODE command to change channel modes. Supports all
7306 channel modes defined by the protocol specs except ban and invite
7307 lists. (Also, private channel key mode is supported but support for
7308 setting private channel key in client is missing, thus, this mode
7309 has no effect on client side (except that server requires that the
7310 client uses private channel key and normal channel traffic does not
7313 Also, invite mode works per se, but INVITE command does not work
7314 yet correctly, so you can set channel as invite only channel but
7315 inviting clients to the channel does not work (it is yet to be
7316 thought what's the best way to do it).
7318 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7319 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7320 Implemented CUMODE command to change user's mode on the channel.
7321 Supports all modes defined by the protocol specs.
7323 * Added NAMES command reply to return users modes on the channel.
7325 * Removed unnecessary and slow ciphers from lib/silccrypt.
7327 * Set SO_KEEPALIVE option to connection sockets by default.
7329 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7331 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7332 redefined the Notify Payload into protocol specs.
7334 * Added silc_id_payload_parse_id to get ID directly from raw
7337 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7339 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7340 accept searching by Client ID as well.
7342 * Added support for LEAVE and SIGNOFF notify types in client library.
7344 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7345 to parse ID Payload from raw data.
7347 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7349 * Added flags parameter into silc_ske_assemble_security_properties
7350 function in lib/silcske/silcske.[ch].
7352 * Changed notify client operation to fit better for notify messages
7353 sent by server. The notify payload received from server is now
7354 passed to the application (after parsing it to SilcNotifyPayload).
7355 It is application's responsibility to retrieve the arguments
7356 from the payload and show the message the way it wants. The message
7357 sent by server is implementation specific.
7359 * Changed public keys to comply with the protocol specification.
7360 Old public keys are not supported anymore and are not compatible.
7362 * Removed nickname from Channel Payload as the latest draft removed
7363 it. The client must resolve the nickname from the NAMES command
7364 reply received when it joined the channel.
7366 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7368 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7370 * Fixed some errors in protocol specification drafts.
7372 * Created lib/silccore/silcnotify.c to implement Notify Payload
7373 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7374 generic payloads described by protocol specifications. The file
7375 includes implementations for ID Payload and Argument Payload.
7377 * Changed Command Payload implementation to use the new Argument
7378 Payload. Changed command_xxxx_payload to command_payload_xxxx
7379 to comply with SILC coding conventions.
7381 * Added suppport for Argument Payload handling in Notify Payload
7382 implementation as protocol requires it. Added the new support
7383 into server and client lib as well.
7385 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7387 * Added support for multiple nicknames on same channel. [n] is
7388 added locally to the nickname if there are more than one same
7389 nicknames on the channel.
7391 * Server now sends all nicknames that matched WHOIS request.
7392 Client also shows the list received from server.
7394 * Added TOPIC command to client side. User can now set and show
7395 current topic on channel.
7397 * Added MOTD command to client and server. Also, server sends the
7398 motd when client connects to the server.
7400 * Changed version strings to comply ISO 8601.
7402 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7404 * Fixed protocol error handling in client library. It should now
7405 cope even if the SKE fails for some reason.
7407 * Made new protocol specification drafts for submitting to IETF.
7409 * Implemented TOPIC command to server in silcd/command.c.
7411 * Added two new notify types into lib/silccore/silcnotify.h:
7412 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7413 notify nickname change and topic setting/change on a channel.
7415 * API change of command_reply operation in client library. The
7416 application gets now the status type received from server as well.
7418 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7420 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7422 * Cras fixed and optimized the packet handling even further and
7423 it should work now. Minor change to the prototype of function
7424 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7426 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7428 * Added new function into lib/silcutil/silcschedule.[ch]:
7429 silc_schedule_with_fd to select() a specified fd. The function
7430 returns after timeout expires or data arrives or goes. The
7431 function is used by packet routines to wait that all data is
7432 received from network.
7434 * Fixed data reading from network in lib/silccore/silcpacket.c.
7435 The code now assures that all data is read from the fd and then
7436 continues packet processing. This was a bug fix since the code
7437 used to drop some data in some circumstances.
7439 * Added new function into lib/silcclient/client.[ch]:
7440 silc_client_start_key_exchange to start key exchange after
7441 connection has been established to server. The code internally
7442 now uses this funtion but its main purpose was to provide it
7443 for applications that perform their own connecting. After
7444 application has created a connection it merely calls this
7445 function to start the key exchange between client and server.
7446 The library takes care of everything else after that.
7448 Updated also lib/silcclient/README to explain the usage of
7451 * Do not send to application information that connection has
7452 been established. Application gets notified it by connect
7455 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7457 * Applied cras's patch to add silc_schedule_one function. The
7458 function runs scheduler once and returns.
7460 * Fixed the scheduler after cras messed it up. The timeout
7461 handling works now as it's supposed to work.
7463 * Added into lib/silccore/ silcnotify.h to include notify
7464 message types support. Changed silc_server_send_notify*
7465 functions, in server.[ch], to support those new notify types.
7466 Added the support for the notify types into client library,
7467 as well. Added new notify client operation into ops.h in
7470 * Changed silc_server_packet_send_to_channel to send normal
7471 packets instead of just channel message packets. The function
7472 is now used to send the notify packets to channels. It is not
7473 used to send channel message packets anymore, as server never
7476 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7477 va_arg()s as it seems to require it nowadays. I guess, if SILC
7478 is compiled with older va_arg() the new code should work anyway.
7480 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7482 * Splitted core library. Core library (lib/silccore) includes
7483 now only SILC protocol specific core (and common) components.
7484 Created new utility library (lib/silcutil) that includes more
7485 generic purpose stuff. The stuff for util library was taken
7486 from the old core library. This was minor and easy split.
7488 * Created SILC Client Library (lib/silcclient) that includes
7489 implementation of the SILC client without user interface. This
7490 was major move from silc/ directory. The code has been changed
7491 so that it is transparent towards the user interface. The
7492 silc/ directory includes now the same user interface as before
7493 and it uses the new client library. Read lib/silcclient/README.
7494 Basicly, the client library performs everything else related
7495 to SILC except user interface handling. Also, configuration
7496 files are considered to be part of user interface and library
7497 does not handle them.
7499 This change also changed a lot of structures, function naming etc.
7500 Most important change was that SilcClientWindow object was
7501 renamed to SilcClientConnection in the client library. Created
7502 also new file lib/silcclient/ops.h. Also added new files
7503 silc/local_command.[ch] and silc/client_ops.[ch].
7505 All these changes were made to make it easier for user interface
7506 designers to create what ever user interface for the SILC client
7509 It is also expected that the server will be moved to lib
7510 directory as well and SILC Server Library will be created;
7511 sometimes in the future.
7513 * Removed Local commands from lib/silccore/silccommand.h as
7514 they are application specific and new client library does not
7515 handle any of those anymore.
7517 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7518 old client implementation in silc/.
7520 * Added support for callback functions in SILC_LOG_* macros.
7521 Application can now set its own callbacks that will be called
7522 instead of using the default functions that will always print
7523 the debug messages to stderr (or stdout). Also, debugging can
7524 now be disabled by setting silc_debug to FALSE and re-enabled by
7525 setting it to TRUE. Note, that logging will still work even
7526 if debugging is disabled.
7528 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7529 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7530 silc_log_reset_debug_callbacks.
7532 * To enable debugging in silc client one must give now -d
7533 option on command line.
7535 * Changed silc_schedule_init to automatically allocate task queues
7536 if they are not allocated before calling it.
7538 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7540 * Added GMP 3.1 into math library.
7542 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7544 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7545 a channel in SILC network. The packet is used by servers and
7546 routers to notify other routers that user has left a channel.
7547 This little feature was missing until now. Added the feature
7548 to protocol specification as well.
7550 Added functions: silc_server_send_remove_channel_user and
7551 silc_server_remove_channel_user into server.[ch].
7553 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7554 lib/silccore/silcpacket.h. However, they are not implemented
7557 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7559 * Fixed joining to a channel and sending channel messages
7560 between server and router. The channel message sending should
7561 now work inside a cell.
7563 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7565 * Fixed the private message sending between server and router.
7566 The private message sending should now work inside a cell.
7568 * Added silc_server_replace_id into server.[ch] to replace
7569 existing ID in the SILC network.
7571 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7572 and silc_idlist_replace_server_id into idlist.[ch] in server.
7574 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7576 * Fixed the server to server connections. Server can again now
7577 connect to router. Router to router connections probably does
7580 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7582 * Added dynamic protocol registering support. Now protocols can
7583 registered and unregistered on the fly. Patch by cras.
7585 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7587 * Added lib/contrib directory to hold routines that some platforms
7588 don't have but are needed by SILC.
7590 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7591 into lin/contrib to provide getopt() and getopt_long() for
7592 those who don't have it.
7594 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7596 * Added AWAY command to client. When away message is set and
7597 client receives a private message packet the client automatically
7598 replies to the sender with the away message.
7600 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7601 bug seemed to be the cause of recent problems when compiling
7604 * Added version detection support to SKE protocol specification
7605 and added the new changes to the SKE implementation as well.
7606 There were other minor changes in the SKE protocol as well.
7608 Many changes in lib/silcske/silcske.[ch] and in
7609 lib/silcske/payload.[ch].
7611 * Added ^U functionality, clear input line. Patch from cras.
7613 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7615 * Mainly small bugfixes on core library. Fixed some debugging
7616 logging and buffer overflow in silclog.c.
7618 * Updated config.sub and config.guess on the distribution tree.
7620 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7622 * Added command lagging support in server. Client may execute
7623 commands now only once in two seconds.
7625 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7627 * Optimized packet reception. MAC computation and checking is now
7628 also more optimized. A lot previously duplicated code is now
7629 used as generic by both client and server.
7631 * Fixed key pair generation in clientutil.c
7633 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7635 * Added into lib/silccore/silcbufutil.[ch] new function;
7636 silc_buffer_realloc.
7638 * Moved generic packet sending/encryption functions to
7639 lib/silccore/silcpacket.[ch] from client and server. Some
7640 rewriting of the functions.
7642 * Moved all generic packet reception/decryption functions to
7643 lib/silccore/silcpacket.[ch] from client and server. The
7644 packet processing is now much cleaner in both client and server.
7645 These were major changes in both client and server.
7647 * Created many common functions in server to do packet sending.
7648 Previously code were duplicated a lot, this has been removed
7651 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7653 * Rewrote major parts of the ID cache system. Don't know
7654 whether it is better now or not but at least the API is more
7657 * Major rewrite on ID cache stuff on client because of the ID
7658 cache API changes. Added idlist.c to client.
7660 * Also major rewrite on ID cache stuff on server as well.
7661 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7662 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7663 in hand, instead they are all put into the ID cache system now.
7664 All server_idlist_* routines uses ID cache now instead of
7665 traversing its own lists (those lists does not exist anymore).
7666 SilcIDList though still exists. Also, SilcXXXEntry's are
7669 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7671 * Finally made the SKE implementation compliant to the protocol
7672 specification. All mp integers are now binary encoded as
7673 opposed being HEX encoded.
7675 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7678 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7679 functions: silc_[encode/decode]_pem. Also added function
7680 silc_encode_pem_file to PEM encode with newlines ('\n') for
7683 * SILC public keys are now encoded either PEM or binary. Same
7684 option is for private keys as well. By default private keys
7685 are binary encoded and public keys PEM encoded. Silly HEX
7686 encoding were removed.
7688 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7689 function to create fingerprints.
7691 * Fixed a bug in SHA1; does not change the original data anymore.
7693 * Partly implemented INFO command on client and server side.
7694 Fixed CLEAR command. Changes to SERVER command; show current
7695 server(s) when giving command without arguments. Added
7696 VERSION command to client.
7698 * Added check to server that unregistered connections cannot
7699 execute commands (unless it is specificly allowed).
7701 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7703 * Fixed screen refresh.
7705 * Fixed channel joining bug from client. On some circumstances
7706 client tried to join to a channel it had already joined.
7708 * Added public key verification process into client's protocol.c.
7709 The client now verifies the public key from user and saves
7710 it into ~./silc/serverkeys/ directory.
7712 Added into: clientutil.[ch]: silc_client_verify_server_key.
7714 * Changed SKE protocol's silc_ske_initiator_finish function
7715 to accept callback function that verifies the received public
7716 key. Removed old silc_ske_verify_public_key function.
7718 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7720 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7721 silc_pkcs_private_key[_data]_set.
7723 * Made the password and public authentication more cleaner in
7724 server's protocol.c.
7726 * Removed historic and obsolete protocol `channel_auth' from
7727 both client and server.
7729 * Removed wrong way of sending command status messages from
7730 server to client in server's command.c. The old way violated
7731 protocol specification.
7733 Changes to silccore/silccommand.[ch]: removed
7734 silc_command_encode_status_payload -> not needed anymore,
7735 changed silc_command_encode_payload_va to accept extra
7736 argument on variable argument list. The argument type must
7737 now be provided to the function. Also, added new function:
7738 silc_command_encode_reply_payload_va which is same as
7739 normal command_encode_payload_va except command status type
7740 is provided as extra argument.
7742 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7744 * Added ~./silc directory handling. The directory includes the
7745 public and private keys for the client.
7747 Added silc_client_check_silc_dir, silc_client_create_identifier
7748 and silc_client_load_keys.
7750 * Implemented SILC protocol compliant public key. Added public
7751 and private key saving to and loading from files.
7753 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7754 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7755 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7756 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7757 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7759 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7760 silc_pkcs_load_[public/private]_key.
7762 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7764 * Added silc_server_get_route (route.[ch]) to get connection
7765 data for the fastest route for given ID.
7767 * Implemented INVITE command on client and server. The command
7768 were re-defined in the SILC Protocol Specification and the
7769 implementation now complies with the specification.
7771 * Implemented PING command on client and server.
7773 * Implemented NAMES command on client and server. The server side
7774 supports currently only normal server not router server yet.
7775 Some changes to NAMES definition in SILC protocol specification.
7777 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7779 * Implemented LEAVE command on client and server.
7781 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7782 again. This change was made to the protocol as well. Server
7783 should not violate the protocol specification anymore.
7785 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7787 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7788 was tested. SOCKS4 was not but should work anyway.
