3 * Upgraded the protocol version to 1.1, updated protocol specs
6 * Added the nickname as new argument to NICK_CHANGE notify and
7 added it to protocol specs and implemented it to client and
8 server. Protocol TODO #3. Affected files are silcd/idlist.[ch],
9 silcd/command.c, silcd/packet_receive.c, packet_send.[ch], and
10 lib/silcclient/client_notify.c.
12 * Added the killer's client ID to the KILLED notify and added
13 it to protocol specs and implemented it to client and server.
14 Protocol TODO #13. Affected files are silcd/command.c,
15 silcd/packet_receive.c, packet_send.[ch],
16 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
17 The killer's client entry is now returned to application in
18 the `notify' client operation.
20 * Fixed the Max Argument fields that had too large value set
21 in the protocol specs. Protocol TODO #14.
23 * Added the LEAVE command reply to return the ID of parted
24 channel. Updated protocol specs and implemented it to the
25 client and server. Protocol TODO #15. Affected files are
26 silcd/command.c, lib/silcclient/command_reply.c. The channel
27 entry is now returned to application in the `command_reply'
30 * Rewrote the version SKE version checking in client libary
31 and in server to use the silc_parse_version_string. Affected
32 files are lib/silcclient/protocol.c, silcd/protocol.c.
34 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
35 commands that was missing it, and updated protocol specs and
36 the server implementation. Protocol TODO #10. The affected
37 file is silcd/command.c.
39 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
40 generic reply to a generic request (REQUEST flag), and
41 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
42 way. A draft-riikonen-silc-flags-payloads-00.txt is written
43 to define the payload for DATA flag. Added the flags to
44 the implementation. Protocol TODO #9. Affected file is
45 lib/silccore/silcchannel.h.
47 Changed the client library to return the message length
48 to application as well in the channel_message and private_message
49 client operations. Affected files are
50 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
51 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
52 and lib/silcclient/client_ops_example.c.
54 * Added two new channel modes: SILC_CMODE_SILENCE_USERS

56 the channel. Updated protocol specs and impelemented this
57 to client and server. Protocol TODO #6. Affected files are
58 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
59 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
61 Added new options m and M to CMODE command in Irssi SILC
62 client to set these modes.
64 * Deprecated all administrative commands from SILC protocol
65 since they are highly implementation specific commands.
66 Updated protocol specs. Moved the old commands in
67 implementations to private range of command types. Affected
68 files are silcd/command.c, lib/silcclient/command.c and
69 lib/silcclient/command_reply.c. Protocol TODO #8.
71 * Fixed a bug in server where sending unknown command crashes
72 the server. Affected file silcd/command.c.
74 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
76 * Added SILC_PROTOCOLVERSION macro to check protocol version
77 of a socket connection. The affected file is
78 lib/silcutil/silcsockconn.h.
80 * Added better error logging in rekey protocol. Affected file

84 file lib/silcske/payload.c.
86 * Fixed the rekey protocol with PFS, which was totally broken.
87 Affected file silcd/protocol.c.
89 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
91 * Some client implementations quit network by doing first LEAVE
92 and then immediately SIGNOFF (like Bombyx). We now do check
93 after a short time after LEAVE notify and check whether the
94 client is still valid after LEAVE, and if not we remove it from
95 cache. Affected file is lib/silcclient/client_notify.c.
97 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
99 * Merged version 1.1.4 of zlib. Even if it not currently in use,
100 it's good not to have security holes here.
102 * Fixed a negative refcount situtuation for the config context.
103 Affected file is silcd/serverconfig.c.
105 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
107 * ROBOdoc documented lib/silcutil/silcutil.h.
109 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
111 * Optimized even more the SilcPacketContext structure. Now
112 totally saved 16 bytes of memory per context after optimization.
113 Affected files are lib/silccore/silcpacket.[ch].
115 * Made strict checks for valid SILC IDs. Affected file is
116 lib/silccore/silcid.c.
118 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
120 * Changed the object argument for silc_cipher_register,
121 silc_hash_register, silc_hmac_register and silc_pkcs_register
122 to const. Affected files are lib/silccrypt/silccipher.[ch],
123 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
125 * Changed the silc_get_username and silc_get_real_name to
126 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
128 * Fixed the Irssi SILC Client to use the silc_get_username and
129 silc_get_real_name insted of glib routines since the glib
130 routines only corrupt stack. Fixes the Irssi SILC to work in
131 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
133 * Fixed the Irssi to not use g_get_home_dir since it crashes
134 or returns garbage on cygwin and corrupts stack. Added function
135 get_home_dir to Irssi routines. Affected files are
136 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
138 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
140 * Made some structure optimizations. SFTP memory FS MemFSEntry
141 entry structure. Optimized SilcTask structure. Optimized
142 SilcPacketContext structure.
144 Affected files lib/silcsftp/sftp_fs_memory.c,
145 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
147 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
149 * And yet again reverted back the config thing since Johnny
150 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
153 * Fixed memory leaks from config object. Affected files are
154 silcd/serverconfig.[ch].
156 * Added support for adding new connections to the server in rehash.
157 After rehash they take effect.
159 Added support for changing the maximum allowed connections in
160 rehash. The number can grow but going smaller is not supported.
162 Added function silc_server_num_sockets_by_remote to the
163 silcd/server_util.[ch].
165 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
167 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
169 * Added preliminary checking during config parsing for a valid
170 public/private key and removed further checks in the code.
171 Affected files are silcd/serverconfig.[ch], server.c.
173 * Moved functions silc_server_drop() and silc_server_daemonise()
174 from server.c to silcd.c since they are stricly related to
175 the application activity.
177 * Reverted a small part of the automatic ref/unref since
178 it caused a double unref in some situations. Affected
179 files are silcd/silcd.[ch], server.c, serverconfig.c.
181 * Added some .cvsignore files in the lib directory.
183 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
185 * Fixed silc_net_gethostbyaddr to correctly resolve by
186 address. Affected file lib/silcutil/silcnet.c.
188 * Fixed the notify relaying to client. The HMAC to be used
189 with relayed packets ws wrong and caused decryption failure
190 at the client end. Affected file is silcd/packet_receive.c.
192 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
194 * Created new branch silc_protocol_1_0_branch.
196 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
198 * Changed the silc_server_config_* routines to be SilcServer
199 independent. They are now officially application specific code
200 and not part of generic server implementation. Affected files
201 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
203 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
205 * Added automatic referencing of config context in the
206 silc_server_config_alloc, and automatic unreferencing in the
207 silc_server_config_destroy. Affected files are
208 silcd/serverconfig.[ch], silcd/silcd.c.
210 * Fixed the silc_log_quick handling in the logging routines.
211 It didn't log quickly when it was TRUE. Affected file is
212 lib/silcutil/silclog.c. Also the flush delay was set even
213 if it was 0 in config file. Affected file is
214 silcd/serverconfig.c.
216 * Added support for changing key pair of the server in rehash.
217 Affected file silcd/server.c.
219 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
221 * Fixed the TOPIC_SET notify to not cras. It changed the topic
222 too early, before getting the channel entry. Affected file
223 is silcd/packet_receive.c.
225 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
227 * Added functions silc_server_config_[ref/unref], these are used
228 to prevent that the config object is destroyed.
230 No longer directly affect global variables silc_log_quick and
231 silc_log_delay, they are first cached inside the config object
232 and then applied with silc_server_config_setlogfiles().
234 silc_server_config_set_defaults() is now internal to
235 serverconfig.c, there are no reasons to show this internal stuff
238 Affected files are silcd/serverconfig.[ch].
240 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
241 fprintf's to stderr, since some code may be executed again after
242 the server went into the background. Affected files are
245 * Added rehash support. Added function silc_server_rehash() that
246 will perform all the basic tasks of the rehashing procedure.
248 * Added command line option `-x, --hexdump'. This will enable the
249 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
250 The option `--hexdump' implies `--debug'.
252 * Fixed a bad bug in the logging APIs (silcutil library) where
253 the application would crash after calling silc_log_reset_all().
255 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
257 * Fixed the KICKED notify handling in client library to
258 correctly remove the channel and all entries from the
259 channel when I was kicked. This bug crashed the client.
261 Fixed yet another but in KICKED notify handling to remove
262 the kicked client correctly from the channel.
264 Affected file is lib/silcclient/client_notify.c.
266 * Fixed a minor bug in looking up correct client entry
267 in KICKED notify in server. Affected file is
268 silcd/packet_receive.c.
270 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
271 sources correctly to distribution. Fixes --with-gmp option.
273 * Removed the manual rehashing from ID Cache, and changed it
274 to use the SILC Hash Table's auto rehash feature. Affected
275 file is lib/silccore/silcidcache.c.
277 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
279 * Fixed a bug in the silc_client_nickname_format function that
280 handles the multiple same nickname formatting. Two clients
281 with same nickname caused problems after the first one left
282 and rejoined. It didn't format the nickname correctly.
283 Affected file is lib/silcclient/idlist.c.
285 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
287 * Don't change the topic if olod topic is same as new one.
288 Affected file is silcd/packet_receive.c.
290 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
292 * Added cross-reference support to the SILC Documentation
293 generator. All types across all HTML files are now cross-
294 referenced. Affected files util/robodoc/generator.c and
295 scripts/silcdoc/silcdoc.
297 * Added file lib/silcutil/silctypes.h to include all the
298 arithmetic type definitions and some macros. Removed
299 includes/bitmove.h and moved macros to silctypes.h.
301 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
303 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
305 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
307 * Added `type' argument to silc_id_payload_parse_id function which
308 now returns the type of the ID to the sent pointer. Affected
309 file is lib/silccore/silcid.[ch].
311 * Added check for CMODE_CHANGE notify type that mode change is
312 allowed by the sender. Affected file silcd/packet_receive.c.
314 * Added check for CUMODE_CHANGE notify type that mode change is
315 allowed by the sender. Affected file silcd/packet_receive.c.
316 Added the ID type as CUMODE_CHANGE notify type as argument
317 to the `notify' client operation. Affected files are
318 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
320 * Added function silc_client_add_server to the client library.
321 Added support for resolving also channel and server info when
322 received unknown entity in notify packet. Affected files are
323 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
325 * Added function silc_command_get_status to return the command
326 status from the command reply's argument payload. Affected files
327 are lib/silccore/silccommand.[ch].
329 * Added check for KICKED notify type that the kicking is
330 allowed by the client. Affected file silcd/packet_receive.c.
332 * Created function silc_get_input which can be used to get input
333 (echo on or off) from user on command line. Affected files are
334 lib/silcutil/silcutil.[ch].
336 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
338 * Optimized silc_server_packet_relay_to_channel function.
339 Added new function silc_channel_message_payload_encrypt which
340 can be called directly if channel message payload needs to
341 be encrypted and is already encoded (no need to call _encode
342 function). Packet relaying is now done by router without any
343 extra memory allocations. Affected files are
344 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
347 * Fixed the INVITE notify handling. It took wrong arguments
348 as invite list and invite delete. Affected file is
349 silcd/packet_receive.c.
351 * Added check for TOPIC_SET notify type that the topic change is
352 allowed by the client. Affected file silcd/packet_receive.c.
354 * Added check for INVITE notify type that inviting is allowed by
355 the client. Affected file silcd/packet_receive.c.
357 * Changed the silc_server_client_on_channel to return the
358 SilcChannelClientEntry as well. Moved the function
359 silc_server_check_cmode_rights to server_util.[ch].
360 Affected files are silcd/server_util.[ch], silcd/command.c.
362 * Added function silc_server_check_umode_rights to check whether
363 changing client's user mode is allowed. Added check for
364 UMODE_CHANGE notify type that the umode change is allowed
365 by the client. Affected files are silcd/server_util.[ch],
366 silcd/packet_receive.c and silcd/command.c.
368 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
370 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
371 ID length. It ignored that ID can be IPv6 based as well.
372 Affected file lib/silccore/silcpacket.h.
374 * Fixed the silc_id_id2str and silc_id_str2id to take the
375 IPv6 address offset's into consideration. Affecte file is
376 lib/silccore/silcid.c.
378 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
380 * Fixed the internal Unix scheduler functions to check for
381 NULL context they may receive. The affected file is
382 lib/silcutil/unix/silcunixschedule.c.
384 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
386 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
387 can specify different directory with --home command line
388 parameter. Affected files irssi/src/silc/core/client_ops.c,
391 * SILC-specific commands aren't now executed if the active server
392 isn't of SILC-type, so there won't be problems with having
393 IRC and SILC protocol support in same client. Affected files
394 irssi/src/silc/core/silc-channels.c, silc-servers.c,
397 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
399 * Improved the signal support in SILC Schedule. Added new
400 function silc_schedule_signal_call which is used by application
401 to mark a signal to be called. It is now safe to perform
402 any kind of tasks in signal callbacks since it is guaranteed
403 that the application specified signal callback is called
404 after the signal is over. Affected files are
405 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
407 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
409 * Added `name' field to SilcChannelPrivateKey to represent
410 application given name for the key. Moved also the context from
411 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
412 Added the `name' argument also to the function
413 silc_client_add_channel_private_key.
415 Added function silc_client_current_channel_private_key to set the
416 current channel private key in use.
418 Added "change" command to KEY command which can be used to change
419 the current channel private key. Bound the command also to
422 Also affected files lib/silcclient/client_channel.c,
423 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
425 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
427 * Added silc_rng_get_byte_fast function in to the
428 lib/silccrypt/silcrng.[ch].
430 * Changed the interface of silc_packet_assemble and the
431 silc_packet_send_prepare. If silc_packet_assmble is now
432 called the application does not call silc_packet_send_prepare
433 because the library will call it automatically. These
434 interfaces now also return a reference to the outgoing buffer
435 which includes the assembled packet, which the application can
436 use to encrypt the packet.
438 Affected files are lib/silccore/silcpacket.[ch],
439 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
440 silcd/packet_send.c, server_backup.c and packet_receive.c.
442 * Fixed a packet sending bug on very high load, where outgoing
443 packet queue wasn't handled correctly and packets got corrupted.
444 Affected files are lib/silcutil/*/silc*sockconn.c,
445 lib/silcclient/client.c and silcd/server.c.
447 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
449 * Added macro SILC_PACKET_DATALEN which can be used during
450 packet assembling to check whether the data to be added to
451 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
452 len is truncated until it fits it.
454 Added checks for maximum length of channel message payload and
455 private message payload also.
457 Added checks for maximum packet length in server and in
460 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
461 lib/silcclient/client.c, lib/silccore/silcchannel.c and
462 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
463 lib/silcclient/client_prvmsg.c.
465 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
467 * Added silc_server_packet_queue_purge call to the
468 silc_server_disconnect_remote to assure that all data in the
469 queue before disconnecting is sent to the network. Affected
472 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
474 * Added the deleting of server's own ID cache entry to the
475 silc_server_free function. Free also everything else that
476 has been allocated in silc_server_init. The affected file
479 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
481 * Added functions silc_parse_version_string, silc_version_to_num,
482 and silc_ske_parse_version to parse SILC protocol style version
483 strings. Affected files lib/silcutil/silcutil.[ch] and
484 lib/silcske/silcske.[ch].
486 * Added new configuration params: version_protocol, version_software
487 and version_software_vendor to specify what version the remote
488 host must at least be to be able to connect to server. The vendor
489 string can be regex matched too. Added new function
490 silc_server_connection_allowed to check maximum number of allowed
491 connections, and allowed versions for incoming connections.
492 Affected files are silcd/server.c, server_util.[ch] and
495 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
497 * Added preliminary support for signals in scheduler. The
498 signals we care about are now blocked always when the scheduler
499 is locked. This way we can synchronise the use of signal with
500 scheduler. It is guaranteed that when signal occurs the scheduler
501 is not locked, and thus new tasks can be safely added to the
504 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
505 to silc_schedule_internal_init and silc_schedule_internal_uninit.
506 Added new platform specific routines
507 silc_schedule_internal_signals_[un]block and
508 silc_schedule_internal_signal_[un]register.
510 Added new functions to SILC Schedule API:
511 silc_schedule_signal_[un]register. Each signal that application
512 is going to use should be registered to the scheduler.
514 Affected files are lib/silcutil/silcschedule.[ch],
515 lib/silcutil/*/silc*schedule.c.
517 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
519 * Check for unauthenticated client and server in the
520 silc_server_new_client and silc_server_new_server functions.
521 Affected file silcd/packet_receive.c.
523 * Added function silc_string_is_ascii to check whether given
524 string is 7-bit ASCII string. Affected files are
525 lib/silcutil/silcutil.[ch].
527 * Added function silc_id_is_valid_server_id into the
528 silcd/serverid.c and added checking for valid Server ID's in
529 silc_server_new_server. The Server ID must always be based
530 on the server's public IP address.
532 * Added logging of DISCONNECT packet message in the server.
533 Affected file silcd/server.c.
535 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
537 * Changed all library interfaces that use Global RNG to also
538 accept SilcRng as argument. Affected files are
539 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
540 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
541 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
542 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
545 * Added function silc_pkcs_generate_key to the
546 lib/silccrypt/silcpkcs.[ch] for applications so that they
547 don't need to do pkcs->pkcs->init calls anymore.
549 * Remove SilcSocketConnection from the SFTP API since it really
550 wasn't needed there. The application has the information
551 saved in its contexts anyway and the SFTP layer doesn't need
552 know about it. Affected files lib/silcsft/silcsftp.h and
553 lib/silcsftp/sftp_[server/client].c.
555 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
556 The SilcSimContext is not SilcSim.
558 * Fixed possible buffer overflows in silc_id_render in the
559 lib/silcutil/silcutil.c.
561 * On EPOC the global crypto module lists are not used at all
562 in the crypto library. Added support for using the constant
563 algorithm list on EPOC. Affected files are
564 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
567 * Fixed the handling of third parameter of KICKED notify, since
568 it was mistakenly updated to SILC Protocol 1.0 even though it
569 is to be included in 1.1. Since it is not in 1.0 it is not
570 mandatory, and this fix now handles it only if it is provided,
571 and it is not error if it is not provided. Affected file
572 lib/silcclient/client_notify.c.
574 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
576 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
577 client. Affected file irssi/src/silc/core/client_ops.c.
579 * Merged with Irssi 0.8.4 from irssi.org CVS.
581 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
583 * Check for valid socket connection in client entries before
584 sending any messages. Fixes a crash, but doesn't fix some
585 other underlaying bug that is lurking there. Affected
586 file silcd/packet_send.c.
588 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
590 * $usermode, $cumode and $cumode_space expandos shouldn't do
591 anything with non-SILC server records. Affected file
592 irssi/src/silc/core/silc-expandos.c
594 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
596 * Fixed the silc_net_check_[host/local]_by_sock to support
597 IPv6 bound sockets as well. Now they can return IPv6 addresses
598 as well. Affected file lib/silcutil/silcnet.c.
600 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
601 Affected lib/silcutil/unix/silcunixnet.c.
603 * Fixed ID rendering (at least on some platforms, not NetBSD)
604 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
606 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
608 * Added silc_hash_public_key and silc_hash_public_key_compare
609 functions to be used with SilcHashTable. They can be used to
610 hash public keys and compare public keys in hash table. Affected
611 file lib/silcutil/silcutil.[ch].
613 * Added support for specifying multiple public keys for Client
614 connection section in server configuration file. This makes it
615 possible to accept multiple public keys from same host, or to
616 make a section that accepts any incoming host, and have the
617 accepted public keys listed in the section.
619 Added functions silc_sever_[find/get]_public_key, added the
620 support for this actually to all connection sections but only
621 the Client section is currently allowed to specify multiple
624 Affected files are silcd/server.c, server_internal.h,
625 command.c, protocol.c, server_util.[ch], packet_receive.c.
627 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

631 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
633 * If silc_debug is TRUE, also output standard logging messages
634 to stderr with the debug output.
636 Made silc_log_reset_all() flushing all channels before returning.
637 Also fixed some documentation typos.
639 Affected files are lib/silcutil/silclog.[ch].
641 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
643 * Fixed the server to check correctly the amount of connections
644 from single host, by checking also the type of the connection.
645 Fixed also the comparison of number of connections and number
646 of allowed connections. Affected files are silcd/server.c,
649 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
651 * Fixed the USERS command reply to save the user's mode on the
652 channel as well. Fixed JOIN command reply to check whether a
653 client is on channel already and not join it twice. Affected
654 file lib/silcclient/command_reply.c.
656 * Added new file silc-expandos.c into irssi/silc/core/ to return
657 various stuff for various signal for the statusbar etc. updating.
658 Now Irssi SILC client prints channel user modes etc. on the
661 * The user mode (like server/router operator changes) is now shown
662 on the Irssi SILC client's statusbar. The affected files are
663 irssi/src/silc/core/client_ops.c, silc-expandos.c.
665 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
667 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
668 to SILC_SCHEDULE_[UN]LOCK macros.

671 files silcd/server.c and silcd/protocol.c.
673 * Fixed -S option parsing in Irssi SILC Client. Affected file
674 irssi/src/silc/core/silc-core.c.
676 * Added silc_buffer_alloc_size function. Affected file is
677 lib/silcutil/silcbuffer.h.
679 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>

692 check the size of 64 bits types with sizeof(). Affected
693 file is lib/silcutil/silcbuffmt.c.
695 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
697 * Removed 0.6.x backwards support.
699 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
701 * Changed all integer type names:
702 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
703 to avoid collisions with other libraries using same type names
706 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
708 * Added `prefer_ipv6' argument to the functions
709 silc_net_gethostbyname[_async]. If it is TRUE it will return
710 IPv6 address over IPv4. If FALSE IPv4 address is returned
711 even if IPv6 address was found. Affected files
712 lib/silcutil/silcnet.[ch].
714 * Added support silc_net_create_connection[_async] to fallback
715 to IPv4 address if IPv6 address could not be used (like if
716 it doesn't work on a specific system). Affected file in
717 lib/silcutil/unix/silcunixnet.c.
719 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>

727 * Added automatic extern "C" { ... } for C++ compilers so the
728 application does not need to define them. Affected file
729 includes/silcincludes.h.
731 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
732 old name went against naming convention. Applications now
733 include "silcclient.h" instead of "clientlibincludes.h".
734 Removed includes/clientlibincludes.h, it is redundant now.
736 * Renamed includes/version.h to silcversion.h.
738 * Added really preliminary support for OS/2 into the util
739 library. Only thread & mutex API is implemented, others
740 are still to be implemented. Created the lib/silcutil/os2/
741 directory. Created also file includes/silcos2.h.
743 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
745 * Added preliminary BeOS support into the util library.
746 Created lib/silcutil/beos/, and implemented all the needed
747 functions to support SILC on BeOS. Created also file

752 * Added proper initializations to silc's irssi code, so it's
753 now possible to load it as module. Affected files
754 irssi/src/silc/core/silc-core.c,
755 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
757 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>

766 * ROBOdoc documented lib/silcutil/silcmemory.h.
767 Added also new function silc_memdup.
769 * Removed lib/silcutil/silcbufutil.h and moved those routines
770 to the lib/silcutil/silcbuffer.h.
772 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
774 * Added `user_count' to the SilcChannelEntry which now tells the
775 number of users on the channel. The user count is now saved
776 in normal server of global channels as well. Affected files
777 silcd/server.c, idlist.h, packet_receive.c and command.c.
779 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

786 KICKED notify printing in Irssi SILC Client. Affected file
787 irssi/src/silc/core/client_ops.c.
789 * Fixed a NICK change bug in client library, to not recreate the
790 client_entry->channels hash table everytime nick is changed.
791 Affected file lib/silcclient/client.c.
793 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
795 * ROBOdoc documented the lib/silcske/silcske.h, and improved
796 the SKE interface a bit.
798 * Fixed padding problem in PKCS#1. The padding was not actually
799 random since the random number generator was used incorrectly.
800 This security bug affects only when encrypting with PKCS#1, and
801 it is not currently used at all in SILC. SILC only use signing
802 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
804 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
806 * Rewrote the notify handling in Irssi SILC client to not call
807 the events as signals. Fixes problems with Perl support.
808 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
810 * Send the auto-nicking NICK command in client library with
811 little timeout after connecting. The affected file is

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

846 * Fixes to the silcd config template. Affected file is
847 doc/example_silcd.conf.in.
849 * Removed type casts from silc_calloc(), conforming to the
850 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
852 * Removed param_name member from client, server, and router
853 section structs, now identifying the param directly.
855 Added CONFIG_FREE_AUTH macro in config file parsing.
857 Affected files are silcd/serverconfig.[ch].
859 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
861 * Fixed command line parameter handling. All SILC initialization
862 is now done in silc_core_init() which also fixes autoconnecting
865 Affected files irssi/src/silc/core/silc-core.c,
866 irssi/src/fe-text/silc.c.
868 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
870 * Added new configuration options and blocks:
871 keepalive_secs, reconnect_count, reconnect_interval,
872 reconnect_interval_max, reconnect_keep_trying and
873 require_reverser_lookup. Added ConnectionParam block, and
874 implemented the connection parameters when connecting as
875 initiator and when accepting connections as responder.
877 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
878 whether given configuration value has been given already.
880 Affected files silcd/serverconfig.[c], server.[c].
882 * Splitted the doc/example_silcd.conf.in. Separated the crypto
883 algorithm parts and created new file silcalgs.conf, that
884 is now included from the example_silcd.conf.in.
886 * Optimized the silc_server_connect_to_router_second to take
887 the connection configuration object from the SilcServerConnection
888 object instead of finding it during the connecting phase.
889 Added the configuration object to SilcServerConnection struct.
890 Affected files silcd/server_internal.h, server.c.
892 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
894 * Add the client on channel after it was resolved at the
895 channel message receiving, and it was not already on the
896 channel. Affected file lib/silcclient/client_channel.c.
898 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
900 * Fixed the public key authentication to allocate always the
901 destination signature buffer instead of using static buffer.
902 Affected file silcd/protocol.c.
904 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
906 * Unified the serverconfig.[ch]'s helper function interface.
907 Affected file silcd/serverconfig.[ch].
909 * Removed doc/example_silc.conf.in since it is redundant.
910 The make install will now install irssi/silc.conf file.
912 * Added new Passphrase and Publickey authentication methods to
913 config file, allowing both public key and passphrase based
914 authentication to be set at the same time.
916 Added `prefer_passphrase_auth' setting in config file which
917 can be used to set to prefer passwd auth if both passwd and
918 public key is set. If not set, public key is preferred.
919 This has effect only when being initiator (responder will try
922 Added support for authentication with passphrase and public key
923 at the same time. The passphrase is tried first always since
924 it is faster to check.
926 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
928 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
930 * Merged the new SILC Config library, with the server parsing
931 support. Read the header file silcconfig.h or the toolkit
932 documentation for the news. Affected files are
933 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]

970 hash algorithm. Affected file lib/silccrypt/silcrng.c.
972 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
974 * Fixed the file transfer's key agreement payload to include
975 zero port also if the hostname is NULL because it could not
978 Call file transfer monitor callback now also if error occurs
979 during key agreement protocol.
981 Changed the silc_client_file_send interface to return the
982 SilcClientFileError instead of session id. The session ID
983 is returned into pointer provided as argument.
985 Check that the file exists locally before sending the
986 file transfer request at all.
988 Affected file lib/silcclient/client_ftp.c, silcapi.h.
990 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
991 error than can occur while key agreement protocol. Affected
992 file lib/silcclient/silcapi.h.

995 is changed and +k mode is set in the channel. Affected file
996 irssi/src/silc/core/silc-channels.c.
998 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
999 SILC_LOG_WARNING to give out Warning and not Error. Affected
1000 file lib/silcutil/silclog.c.
1002 * Fixed the channel message payload decryption in the function
1003 silc_channel_message_payload_decrypt to not modify the original
1004 buffer before it is verified that the message decrypted
1005 correctly. Otherwise, next time it is called with correct
1006 channel key it won't encrypt since the payload is corrupted.
1007 Affected file lib/silccore/silcchannel.c.
1009 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1011 * Do not constantly resize the window. A fix patch by cras.

1017 Affected file lib/silcutil/silcnet.c.
1019 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1021 * Fixed a bug in hash table internal routine for traversing
1022 the table with foreach callback. The current entry may
1023 become invalid in the callback but it was referenced after
1024 the callback returned.
1026 Do not allow auto rehashing of hash table during the
1027 silc_hash_table_foreach operation, for same reasons as it is
1028 not allowed for SilcHashTableList. Affected files are
1029 lib/silcutil/silchashtable.[ch].
1031 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1033 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1034 Win32 DLL. extern's in header files are now declared with
1037 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1039 * Fixed private message handling. It used some old code that
1040 caused the client to crash. Affecte file is
1041 lib/silcclient/client_prvmsg.c.
1043 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1045 * Added function silc_client_add_channel,
1046 silc_client_replace_channel_id, and removed functions
1047 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1048 from client library.
1050 * Added cross reference of the joined channels to the
1051 SilcClientEntry, and changed the SilcChannelEntry's
1052 users list to SilcHashTable. The affected files are
1053 lib/silcclient/idlist.[ch].
1055 * Fixed a bug in hash table tarversing. While the hash table
1056 is traversed with SilcHashTableList the table must not be
1057 rehashed. It is now guaranteed that auto rehashable tables
1058 are not rehashed while tarversing the list. Also defined that
1059 silc_hash_table_rehash must not be called while tarversing
1060 the table. Added function silc_hash_table_list_reset that must
1061 be called after the tarversing is over. The affected files are
1062 lib/silcutil/silchashtable.[ch].
1064 * Changed all hash table traversing to call the new
1065 silc_hash_table_list_reset in server and in client library.
1067 * Added function silc_client_on_channel to return the
1068 SilcChannelUser entry if the specified client entry is joined
1069 on the specified channel. This is exported to application as
1070 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1072 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1074 * Fixed founder regaining problem with JOIN command on normal
1075 server. The notify for mode change must be sent always and
1076 not only if !cmd->pending. Affected file silcd/command.c.
1078 * Fixed the WHOWAS command's reply sending to support the
1079 lists correctly. Affected file silcd/command.c.
1081 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1083 * When sending JOIN command to router for processing the
1084 sender's old command identifier was not saved back to the
1085 sender's command context, fixed now. The affected file is
1088 * Create the key in JOIN command of the router did not return
1089 the channel key, added check for this. Affected file is
1092 * Fixed a channel ID update bug in JOIN command reply. Do
1093 not directly upgrade the ID but call the function
1094 silc_idlist_replace_channel_id if the ID was changed.
1095 Affected file silcd/command_reply.c.
1097 * Fixed memory leaks from command calling if it would fail.
1098 Affected file silcd/command.c.
1100 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1102 * Applied patches from cras:
1104 Memory leak fixes around libaries, irssi window resize fix,
1105 new silclist.h and silcdlist.h, all extern inline changed to
1108 * Removed dotconf from lib/dotconf, not needed anymore.
1110 * Removed TRQ from lib/trq, not needed anymore.
1112 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1113 with server connections. Later this will be configurable
1114 in config file after new config file is done. Affected file
1117 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1119 * Fixed a crash in server related to channel announcements.
1120 Affected file silcd/server.c.
1122 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1124 * Fixed memory leaks in silc_server_create_new_channel*
1125 functions. Affected file silcd/server.c.
1127 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1128 which ID was changed. This way the router will send the
1129 user list for the channel again, and server won't be in
1130 desync in some rare circumstances. Affected file is
1131 silcd/packet_receive.c.
1133 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1135 * Check for NULL socket pointer in the function
1136 silc_server_packet_send_to_channel_real. Affected file
1137 silcd/packet_send.c.
1139 * Fixed the BAN notify handling to correctly remove ban
1140 list. Affected file silcd/packet_receive.c.
1142 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1144 * Fixed some header addition to Toolkit distribution in
1145 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1147 * Added lib/silcclient/client_ops_example.h as an template
1148 file for application programmers to quickly start using
1149 the SilcClientOperation functions in their application.
1150 Updated the lib/silcclient/README as well to tell about this
1151 nice file made available.
1153 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1155 * Call silc_server_remove_from_channels when removing client
1156 entry when NO_SUCH_CLIENT_ID was received. Affected file
1157 is silcd/command_reply.c.
1159 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1161 * Added server & router operator statistics updating. Affected
1162 file silcd/packet_receive.c and silcd/command.c.
1164 * Fixed the SERVER_SIGNOFF notify handling on normal server
1165 not to save the history information for clients. Same was
1166 fixed earlier in remove_clients_by_server function, but not
1167 here. Affected file silcd/packet_receive.c.
1169 * Raised the default connection-retry count from 4 to 7 in
1170 server. Affected file silcd/server.h.
1172 * Cancel any possible reconnect timeouts when we start the
1173 key exchange. Affected file silcd/server.c.
1175 * Do not reconnect on connection failure when SCONNECT was
1176 given. Affected files silcd/server.[ch].
1178 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1180 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1182 * Fixed the NICK command to always give the unformatted
1183 nickname to the one giving the NICK command. If unformatted
1184 nickname is cached already it will be formatted and the
1185 local entry will always get the unformatted nickname.
1186 Affected file lib/silcclient/idlist.c.
1188 * Fixed some double frees from client library commands.
1189 Affected file is lib/silcclient/command.c.
1191 * Fixed CUMODE command in server to assure that no one can
1192 change founder's mode than the founder itself, there was a
1193 little bug. Affected file silcd/command.c.
1195 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1197 * Removed the SilcClientCommandDestructor from the client
1198 libary, it is not needed anymore. Affected files are
1199 lib/silcclient/silcapi.h, command[_reply].[ch],
1200 client_notify, idlist.c.
1202 * Fixed GETKEY command to first resolve client, and then
1203 resolve the server only if the client was not found, instead
1204 of resolving both at the same time. Affected file is
1205 lib/silcclient/command.c.
1207 * Added silc_client_start_key_exchange_cb and lookup the
1208 remote hostname and IP address before starting the key
1209 exchange with server. The affected file is
1210 lib/silcclient/client.c.
1212 * The server's public key is now saved using the IP address
1213 of the server and not the servername for the filename.
1214 The hostname public key filename is checked as an fall back
1215 method if the IP address based filename is not found.
1217 Fixed the GETKEY command to save the fetched server key
1218 in correct filename.
1220 Print the remote server's hostname now when new key is
1221 received during connection process. Affected file is
1222 irssi/src/silc/core/client_ops.c.
1224 * Return always our own public key to the client if it asks
1225 for it with GETKEY command. Affected file silcd/command.c.
1227 * Removed the use_auto_addr variable from default config
1228 file since it was in wrong section. Affected file is
1231 * Fixed TOPIC_CHANGE notification to not route it when it
1232 was sent using silc_server_send_notify_to_channel function.
1233 Affected file silcd/command.c.
1235 * Fixed silc_server_send_notify_kicked to send the kicker's
1236 Client ID also, it was missing. Affected files are
1237 silcd/command.c, silcd/packet_send.[ch].
1239 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1241 * Do not save client history information in SERVER_SIGNOFF.
1242 Fixes the bug in normal server that it does not detect
1243 the client becoming valid after the server becomes back
1244 online. Affected file silcd/server_util.c.
1246 * Added `sock_error' field into the SilcSocketConnection
1247 context. When error occurs during socket operation (read
1248 or write) the error is saved. Added also new function
1249 silc_socket_get_error to return human readable socket error
1250 message. Affected files are lib/silcutil/silcsockconn.[ch],
1251 lib/silcutil/unix/silcunixsockconn.c, and
1252 lib/silcutil/win32/silcwin32sockconn.c.
1254 * The server now prints the socket error message in the
1255 signoff for client. Affected file silcd/server.c.
1257 * Fixed the `created' channel information sending from router
1258 to server in JOIN command. Checks now whether the channel
1259 really was created or not and set it according that.
1261 Fixed the JOIN command to use the client entry's current
1262 ID during the joining procedure instead of the one it sent
1263 in the command (it is checked though), since it can change
1264 between the packet processing and command processing, and
1265 would just case unnecessary pain in the client end. Affected
1266 file silcd/command.c.
1268 * Fixed a channel key payload sending to use correct channel
1269 ID when the server was forced to change the channel's ID by
1270 router. Router sent the key payload with the old Channel ID.
1271 Affected file silcd/packet_receive.c.
1273 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1275 * Call silc_server_save_channel_key only if the key payload
1276 was provided in the JOIN command's command reply. Affected
1277 file silcd/command_reply.c.
1279 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1281 * Fixed silc_mp_sizeinbase to return the value correctly with
1282 MPI. Affected file lib/silcmath/mp_mpi.c.
1284 * Fixed the stop_server signal to correctly stop the scheduler
1285 and gracefully stop the server when SIGTERM or SIGINT signals
1286 are received. Affected file silcd/silcd.c.
1288 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1290 * Simple handling of TERM and HUP signals. Also added some log
1291 flushing call around. Affected file is
1294 * Fixed small bugs in silclog.c. Now buffering output will take
1295 effect after 10 seconds since startup: This will ensure that
1296 no important startup messages are lost. Also output redirection
1297 will preserve original format ([Date] [Type] message).
1298 Affected file is lib/silcutil/silclog.c.
1300 * Added two options to the config file, in the logging section:
1301 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1302 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1304 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1306 * Do not print the warning about log files not being initialized
1307 more than once to avoid excess logging. Affected file is
1308 lib/silcutil/silclog.c.
1310 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1311 the SIM copying in make install in Makefile.am.pre.
1313 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1315 * Rewritten silclog APIs. Globally interesting changes follows:
1316 silc_log_set_files() changed to silc_log_set_file().
1317 silc_log_set_callbacks() changed to silc_log_set_callback().
1318 ROBOdoc documented silclog header file.
1319 SilcLogCb now returns bool to wether inihibit the default
1320 handler or not (to keep the old behaviour return always TRUE).
1321 The new APIs should also fix the problem of the
1322 silcd_error.log file that was written in the current directory.
1325 Log files streams will remain opened after silc_log_set_file()
1326 call, means less CPU usage notably on high traffic servers.
1327 File streams are now full buffered, and flushed to the disk
1328 every 5 minutes, lesses HD activity and CPU usage.
1329 Messages can be redirected, allowing admins to configure
1330 one single logfile for all server messages.
1331 the silc_log_quick global variable to activate fast-logging.
1332 Affected files lib/silcutil/silclog.[ch]
1334 * Changed some code to conform new silclog APIs. Affected
1335 files are doc/example_silcd.conf.in, silcd/server.c
1336 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1339 * Fixed a memory leak that could occur in some situations.
1340 Affected file silcd/serverconfig.c.
1342 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1344 * Added the silc_client_del_client to remove the client from
1345 all channels as well. Affected file lib/silcclient/idlist.c.
1347 * Fixed the client library to correctly remove the client
1348 from all channels when the client entry is being destroyed.
1349 Affected file lib/silcclient/client_notify.c, command.c.
1351 * Added auto-nicking support to the client library. If the
1352 applicatio now sets client->nickname it will be sent to the
1353 server after connecting by the library. This way for example
1354 SILCNICK (or IRCNICK) environment variables will have effect
1355 and always change the nickname automatically to whatever
1356 it is wanted. Affected file lib/silcclient/client.[ch].
1358 * Renamed silc_server_command_bad_chars to the
1359 silc_server_name_bad_chars and moved it to the
1360 silcd/server_util.[ch]. Added also new function
1361 silc_server_name_modify_bad to return nickname that
1362 includes bad characters as new nickname without those
1363 bad characters. This check and modify is now used in
1364 silc_server_new_client when the username is initially set
1365 as nickname, so it must be checked to be valid nickname.
1366 Affected file silcd/packet_receive.c.
1368 * The nickname length is now taken from the packet for real
1369 and not trusted to strlen() since it clearly can return
1370 wrong length for nickname including bad characters. This
1371 also applies to channel names. Affected file silcd/command.c.
1373 * Removed the lib/silcsilm/modules directory. Modules are now
1374 compiled into the lib/silcsim. Fixed the copying of the
1375 modules to follow symbolic links in Makefile.am.pre.
1377 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1379 * Fixed silc_string_regexify list creation. Fixes bugs with
1380 BAN and INVITE commands in server. The affected file is
1381 lib/silcutil/unix/silcunixutil.c.
1383 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1385 * Removed the command destructor entirely from the server's
1386 command and command reply routines. It is not needed, and
1387 its usage was buggy and caused crashes. Affected files are
1388 silcd/command[_reply].[ch].
1390 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1392 * Cancel protocol and NULL sock->protocol if timeout
1393 occurred during protocol. Affected file silcd/server.c.
1395 * Cancel protocol timeouts always before calling the final
1396 callback, to assure that after final callback is called
1397 no other state will be called for the protocol anymore.
1398 Affected file silcd/protocol.c.
1400 * Print error log if incoming connection configuration could
1401 not be found. Affected file silcd/server.c.
1403 * Fixed JOIN command to correctly save the founder mode
1404 to the client on normal SILC server, when the channel
1405 was created by the router. Affected file silcd/command.c.
1407 * Fixed LIST command (hopefully) to send correct reply
1408 packets. Affected file silcd/command.c.
1410 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1412 * The silc_packet_receive_process now returns FALSE if the
1413 read data was invalid packet, and TRUE if it was ok.
1415 The server now checks that if unauthenticated connection
1416 sends data and its processing fails the server will close
1417 the connection since it could be a malicious flooder.
1419 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1421 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1423 * Make sure the warning about error opening a log file is
1424 printed only once and not everytime it fails (produces
1425 too much useless log). Affected file lib/silcutil/silclog.c.
1427 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1429 * Made the silc_server_daemonise() function more readable.
1430 Affected file silcd/server.c.
1432 * Pid file is now optional, the user may comment it out from
1433 the config file. Removed define SILC_SERVER_PID_FILE, we
1434 don't need a default any longer. Affected file
1435 configure.in.pre, lib/Makefile.am.pre.
1437 * Make some use of the pid file. The server now dies at startup
1438 if it detects a valid pid file on his path. The server would
1439 die anyway in this circumstance, because of the bind() failure.
1440 Affected file silcd/silcd.c.
1442 * No longer compiling lib/dotconf.
1444 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1446 * Fixed JOIN command parsing not to crash. Affected file
1447 lib/silcclient/command.c.
1449 * Fied the NICK_CHANGE notify to add the new client entry
1450 even it is resolved. This removes an <[unknown]> nick
1451 thingy bug in the client. Affected file is
1452 lib/silcclient/client_notify.c.
1454 * Do not try to allocate 0 bytes (efence does not like it)
1455 in lib/silccore/silccomand.c when encoding payload.
1457 * Do not take IRCNICK as nickname in Irssi SILC client since
1458 it is not possible to set nickname before hand connecting
1459 the server (TODO has an entry about adding auto-nicking
1462 * Changed the silc_server_command_pending to check whether
1463 there already exists an pending entry with the specified
1464 command, command identifier and pending callback. This is
1465 to fix IDENTIFY and WHOIS related crashes that may register
1466 multiple pending commands with same identifier. Affected
1467 file silcd/command.c.
1469 * Fixed the server to reconnect to the router even if it
1470 was already reconnecting and EOF was received. This to
1471 fix a possibility that the server wouldn't ever try to
1472 auto-reconnect to the router. Affected file silcd/server.c.
1474 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1476 * Fixed the server's password authentication to use the
1477 length of the locally saved password, and not the one
1478 sent in the packet. Affected file silcd/protocol.c.
1480 * Fixed same password authentication problem in the
1481 Authentication Payload handling routines in
1482 lib/silccore/silcauth.c.
1484 * Yet another password authentication problem fixed with
1485 channel password handling in silcd/command.c.
1487 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1489 * If first character of string in silc_parse_userfqdn is '@'
1490 then do not parse it. Affected file is
1491 lib/silcutil/silcutil.c.
1493 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1495 * Fixed minor bug in IDENTIFY command reply sending, which
1496 caused various weird problems during JOIN when it was
1497 resolving names for users. Affected file silcd/command.c.
1499 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1501 * Fixed the IDENTIFY command reply sending to chech better valid
1502 clients. It was possible to send incomplete list of replies.
1503 Affected file silcd/command.c.
1505 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1507 * Added silc_client_command[s]_[un]register functions now to
1508 dynamically register the commands in client library. Removed
1509 the static table of commands. This allows the client library
1510 to call commands without causing the application to know about
1511 what commands library has called.
1513 Removed the INFO command reply kludge to detect when the command
1514 was called by library. Now library use its own command reply
1515 function for INFO command.
1517 Added function silc_client_command_call to call a command.
1518 Application can use it to call command, not access the structure
1521 Now all commands that are sent by the client library (not
1522 explicitly sent by application) use own command reply functions.
1524 Affected files around lib/silcclient/ and in
1525 irssi/src/silc/core/.
1527 * Fixed the WHOIS command reply sending to chech better valid
1528 clients. It was possible to send incomplete list of replies.
1530 Fixed the WHOIS and IDENTIFY to send the request to router
1531 if normal server did not do it and did not find any results.
1533 Affected file silcd/command.c.
1535 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1537 * Moved the internal data from SilcClient context into its
1538 own file, not accesible to application. Affected files
1539 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1540 and other files in client library.
1542 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1544 * Added doc/examples installation target in Makefile.am.pre.
1547 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1549 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1550 commands the found client entry will be removed from the
1551 cache, after notifying application about the error. Affected
1552 file lib/silcclient/command_reply.c.
1554 * Changed the /MSG to check for exact nickname user gave, and
1555 not let `nick' match `nick@host' if it is only one found. Now,
1556 user must type the exact nickname (like nick@host2) even if
1557 there are no more than one same nicks found. This is to avoid
1558 a possibility of sending nickname to wrong nickname since
1559 `nick' could match `nick@host'. Affected file is
1560 irssi/src/core/silc-servers.c.
1562 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1564 * Do not print "you are now server operator" or similar when
1565 giving /away command. Affected files are
1566 irssi/src/silc/core/client_ops.c, silc-servers.h.
1568 * Made the silc_server_command_pending_error_check to send
1569 the same command reply payload it received back to the
1570 original sender of the command. This way all arguments
1571 that was received by the server will be received by the
1572 client too. Affected file silcd/command.c.
1574 * Added the silc_idcache_add to return the created cache entry
1575 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1577 * Add global clients to expire if they are not on any channel.
1578 This is because normal server will never know if they signoff
1579 if they are not on any channel. The cache expiry will take
1580 case of these entries. This is done by normal servers only.
1581 The affected files are silcd/command_reply.c,
1582 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1584 * If server receives invalid ID notification for WHOIS or
1585 IDENTIFY and the ID exists in the lists, it is removed.
1586 Affected file silcd/command_reply.c.
1588 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1589 in client then client entry that it matches is searched and
1590 the nickname is printed on the screen for user. Affected
1591 file irssi/src/silc/core/client_ops.c.
1593 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1595 * Use cache entry expire time in the LIST command reply to
1596 purge old entries from the cache after the LIST command
1597 reply has been received. This way we don't have non-existent
1598 entries in the cache for too long. Affected file is
1599 silcd/command_reply.c.
1601 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1603 * If we are normal server, and we've not resolved client info
1604 in WHOIS or IDENTIFY from router, and it is global client,
1605 we'll check whether it is on some channel. If it is not
1606 then we cannot be sure about its validity and will resolve it
1607 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1608 file silcd/command.c.
1610 * Search channel by name (if possible) rather than by ID
1611 in IDENTIFY command's command reply. Affected file is
1612 silcd/command_reply.c.
1614 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1616 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1617 Updated specs and implemented it. Affected file silcd/command.c,
1618 silcd/packet_send.c and silcd/packet_receive.c.
1620 * Implemented the <founder auth> payload handling in the JOIN
1621 command. If provided all conditions for channel joining
1622 except requirement to provide correct passphrase can be
1623 overrided by the channel founder. Updated the protocol specs.
1624 Affected file silcd/command.c.
1626 Added support for founder auth in JOIN command in client
1627 library. Fixed the parsing of the JOIN command now to support
1628 all options as they should be. The affected file is
1629 lib/silcclient/command.c.
1631 * Optimized the WHOIS and IDENTIFY commands to send the request
1632 to router only if it includes nicknames or other names. If
1633 they include only IDs then check the local cache first before
1634 routing. Affected file is silcd/command.c.
1636 * Added channels topic announcements. Affected file is
1637 silcd/packet_receive.c and silcd/server.c.
1639 * Fixed the silc_server_send_notify_topic_set to really destine
1640 the packet to channel. Affected file silcd/packet_send.c.
1642 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1643 library. Affected file lib/silcclient/client_notify.c.
1645 * Added UMODE announcements. Affected file silcd/server.c.
1647 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1649 * Memory leak fixes in:

1656 lib/silccore/silccommand.c
1657 lib/silccore/silcidcache.c
1662 * ROBOdoc documented the lib/silcske/groups.h file and a
1663 bit changed the interface for better.
1665 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1667 * Update the client entry context in the ID cache after
1668 nick change. Affected file lib/silcclient/command.c.
1669 Fixes the CUMODE command when regaining founder privileges,
1670 and a little WHOIS problem.
1672 * Fixed silc_net_gethostbyname to correctly call the
1673 inet_ntop. Affected file lib/silcutil/silcnet.c.
1675 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1677 * Added IPv6 support checking to the configure.in.pre, added
1678 also --enable-ipv6 option to override the check. Affected
1679 file configure.in.pre.
1681 * The silc_thread_create now calls the start function
1682 directly if threads support is not compiled in. Removes
1683 ugly #ifdef's from generic code. Affected files are
1684 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1686 * Added silc_net_gethostby[name/addr]_async to asynchronously
1687 resolve. Affected files are lib/silcutil/silcnet.[ch].
1689 * Added support for rendering IPv6 based server, client and
1690 channel IDs. Affected file lib/silcutil/silcutil.c.
1692 * Added support for creating IPv6 based server IDs. Affected
1693 file is silcd/serverid.c.
1695 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1697 * Added silc_net_gethostby[addr/name] into the
1698 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1699 routines. Added silc_net_is_ip[4/6]. Affected file is
1700 lib/silcutil/unix/silcunixnet.c. All routines that take
1701 address as argument now supports both IPv4 and IPv6 addresses.
1703 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1705 * Fixed LIST command reply sending in server. Affected file
1708 * Server now sends the kicker's client ID in the KICK notify
1709 to the kicked client. Affected file silcd/command.c.
1711 * The client library now parses the kickers client ID and
1712 UI displays it. Affected files lib/silcclient/client_notify.c
1713 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1715 * Made all payload parsing function prototypes consistent.
1716 They all take now const unsigned char * and uint32 pair as
1717 the payload data instead of SilcBuffer. Changes all around
1718 the source tree. Other unsigned char* -> const unsigned char*
1719 changes around the tree as well.
1721 * Optimized SFTP client and server packet sending not to
1722 allocate new buffer for each packet but to recycle the
1723 first allocated buffer. Affected files are
1724 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1726 * Optimized the SFTP client to use SilcList instead of
1727 SilcDList for requests, because it is faster. Affected file
1728 is lib/silcsftp/sftp_client.c.
1730 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1731 into lib/silccore/silcid.[ch].
1733 Renamed silcpayload.[ch] into silcargument.[ch].
1735 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1737 * If client entry is deleted with active key agreement
1738 session, abort the session.
1740 The silc_client_abort_key_agreement now calls the completion
1741 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1743 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1746 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1748 * Don't use __restrict in older GCC's. Affected file is
1749 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1751 * silc_net_localhost now attempts to reverse lookup the
1752 IP/hostname. Affected file lib/silcutil/silcnet.c.
1754 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1755 command. It can be used to gain founder privileges at
1756 the same time when joining the channel.
1758 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1759 kicker's client ID as well. Updated protocol specs.
1761 Defined that the server must send SILC_COMMAND_IDENTIFY
1762 command reply with error status to client who sent
1763 private message with invalid client ID.
1765 Updated the protocol specification.
1767 * Added silc_server_send_command_reply to send any
1768 command reply. Affected file silcd/packet_send.[ch].
1770 * Added silc_id_payload_encode_data to encode ID payload
1771 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1773 * The server now send IDENTIFY command reply with error
1774 status if client ID in private message is invalid. Affected
1775 file silcd/packet_receive.c.
1777 * Save the server key file with server's IP address in
1778 the filename instead of hostname. The affected file is
1779 irssi/src/silc/core/client_ops.c.
1781 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1783 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1786 * Added libtool support for compiling shared objects in
1787 lib/silcsim. Affected file configure.in.pre and
1788 lib/silcsim/Makefile.am. Original patch by cras.
1790 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1792 * Pid file configuration, and server's config file fixes
1793 patch by toma. Updated CREDITS file.
1795 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1797 * Fixed silc_client_channel_message to not try to decrypt
1798 the message twice if it resolved the destination client
1799 information. This could cause of dropping one channel
1800 message. Affected file lib/silcclient/client_channel.c.
1802 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1804 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1805 lib/silcclient/client.c. This function is used when the SILC
1806 Client is run under some other scheduler, or event loop or
1807 main loop. On GUI applications, for example this may be
1808 desired to used to run the client under the GUI application's
1809 main loop. Typically the GUI application would register an
1810 idle task that calls this function multiple times in a second
1811 to quickly process the SILC specific data.
1813 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1815 * Fixed silc_server_drop() for dropping the supplementary
1816 groups as well, this could cause a security hole on some
1819 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1821 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1824 * Write PID file after dropping privileges. Added -F option
1825 to run server on foreground. A patch by debolaz.
1826 Affected files silcd/server.c, silcd/silcd.c.
1828 * Fixed MOTD to return the MOTD file server name. Affected
1829 file silcd/command.c.
1831 * Added INFO command reply handling to the Irssi SILC Client.
1832 Affected file irssi/src/silc/core/client_ops.c.
1834 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1836 * Fixed the silc_idcache_list_* routines to really support
1837 the dynamic list. Fixes a crash. Affected file is
1838 lib/silccore/silcidcache.c.
1840 * Fixed the LIST command reply to really call LIST command's
1841 pending callbacks. Affected file silcd/command_reply.c.
1843 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1845 * Update conn->local_entry->nickname after giving NICK
1846 command. Affected file lib/silcclient/command.c.
1848 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1850 * Added the [pid] option to the silcd configuration file
1852 Affected files: serverconfig.[ch] and silcd.c
1854 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1856 * Save fingerprint in WHOIS command reply in server.
1857 Affected file silcd/command_reply.c.
1859 * Fixed NICK commands pending callback registration.
1860 Affected file lib/silcclient/command.c.
1862 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1864 * Use ++server->cmd_ident when sending commands in server,
1865 instead of random number. Affected file silcd/command.c.
1867 * Fixed GETKEY command reply to call actually GETKEY pending
1868 command callbacks. Affected file silcd/command_reply.c.
1870 * A bit stricter check for nicknames. Check for same nickname
1871 in NICK command also. Affected file silcd/command.c.
1873 * Do not call INFO command everytime client ID changes, only
1874 during first connecting. Affected file lib/silcclient/client.c.
1876 * Set the new nickname only after successful command reply for
1877 NICK command is returned by server. Affected file
1878 lib/silcclient/command.c.
1880 * Remove nicknames from nicklist during server_signoff notify.
1881 Should fix /NAMES bit more. The affected file is
1882 irssi/src/silc/core/silc-channels.c.
1884 * Added `fingerprint' field to the SilcIDListData in the
1885 silcd/idlist.h to hold the fingerprint of the client's
1888 Send the fingerprint of the client's public key in WHOIS
1891 Affected files silcd/command.c, and silcd/idlist.[ch].
1893 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1894 create fingerprint from given data.
1896 * Show the fingerprint of the client's public key in WHOIS.
1897 Affected files irssi/src/module-formats.[ch] and
1898 irssi/src/silc/core/client_ops.c.
1900 * Format the multiple same nicknames also during JOIN and
1901 NICK_CHANGE notifys. Affected file is
1902 lib/silcclient/client_notify.c.
1904 * Do not print error on screen for invalid private message
1905 payload since it can come if someone is sending private
1906 messages with wrong key. Affected file
1907 lib/silccore/silcprivate.c.
1909 * Fixed multiple concurrent /PING crash. Affected file
1910 lib/silcclient/command.c.
1912 * Changed the wrong ID encoding. All IP addresses must be
1913 in MSB first order in encoded format. They were encoded
1914 wrong and was in LSB format. Affected files are
1915 silcd/serverid.c, lib/silcutil/silcutil.c.
1917 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1919 * Call the `connect' client operation through the scheduler
1920 in case of error. Affected file lib/silcclient/client.c.
1922 * Call the `failure' client operation even if the error
1923 occurred locally during a protocol. Affected file is
1924 lib/silcclient/protocol.c.
1926 * Added support of sending LIST command to router from normal
1927 server. This way normal server can get list of all channels
1928 in the network too. Fixed the channel list sending in the
1929 server too. Affected files are silcd/command.c, and
1930 silcd/command_reply.[ch].
1932 * Added silc_server_update_channels_by_server and
1933 silc_server_remove_channels_by_server. They are used during
1934 disconnection of primary router and in backup router protocol.
1935 Affected file silcd/server_util.[ch], silcd/server.c and
1936 silcd/server_backup.c.
1938 * Fixed channel adding to global list in IDENTIFY command
1939 reply in server. Affected file silcd/command_reply.c.
1941 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1943 * If the incoming packet type is REKEY or REKEY_DONE process
1944 that packet always synchronously. Fixes yet another MAC
1945 failed error on slow (dialup) connections. Affected file
1946 lib/silcclient/client.c and silcd/server.c.
1948 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1950 * Call check_version SKE callback for initiator too. Affected
1951 file lib/silcske/silcske.c.
1953 * Implemented fix for security hole found in the SKE that was
1954 fixed in the specification few days back; the initiator's
1955 public key is now added to the HASH value computation.
1956 Added backwards support for the old way of doing it too, for
1957 old clients and old servers. Affected file is
1958 lib/silcske/silcske.c.
1960 * Enabled mutual authentication by default in SKE. If initiator
1961 is not providing mutual authentication the responder will
1962 force it. This will provide the proof of posession of the
1963 private key for responder. The affected files are
1964 lib/silcclient/protocol.c and silcd/protocol.c.
1966 * Do not cache anymore the server's public key during SKE.
1967 We do mutual authentication so the proof of posession of
1968 private key is done, and if the server is authenticated in
1969 conn auth protocol with public key we must have the public
1970 key already. Affected file silcd/protocol.c.
1972 * Added new global debug variable: silc_debug_hexdump. If
1973 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1974 file lib/silcutil/silclog.[ch].
1976 * Fixed compilation warning due to char * -> const char *.
1977 Affected files lib/silcutil/silcnet.h, and
1978 lib/silccore/silcauth.[ch].
1980 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1982 * Fixed CMODE command when new channel key was created. If
1983 the creation failed the old key was removed. Next time giving
1984 same command would crash the server since the old key was
1985 freed already. Affected file silcd/command.c.
1987 * Fixed the silc_server_announce_get_channels to not crash
1988 on reconnect. Affected file silcd/server.c.
1990 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1992 * Added silc_log_set_debug_string function to set a regex
1993 string to match for debug output. Only the function names,
1994 or filenames matching the given debug string is actually
1995 printed. This way it is possible to filter out those debug
1996 strings that user is not interested in.
1998 Fixed a bug in silc_string_regexify.
2000 Affected files lib/silcutil/silclog.[ch], and
2001 lib/silcutil/unix/silcunixutil.c.
2003 * Changed the -d options in both server and Irssi SILC client
2004 to take the debug string as argument. Affected files
2005 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2007 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2009 * Added silc_hash_babbleprint to create a Bubble Babble
2010 Encoded fingerprint. The encoding is developed by Antti
2011 Huima (draft-huima-babble-01.txt), and it creates human
2012 readable strings out of binary data. Affected file
2013 lib/silccrypt/silchash.[ch].
2015 * Print the babble print now in addition of fingerprint as well
2016 in Irssi SILC client. Affected files are
2017 irssi/src/fe-common/silc/module-formats.[ch],
2018 irssi/src/fe-common/silc/core/client_ops.c.
2020 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2022 * Fixed a security problem found in SKE. The initiator's
2023 public key too is now added to the HASH hash value creation
2024 which is signed by the responder to create the SIGN value.
2025 This will prevent anyone in the middle to lie to the responder
2026 about the initiator's public key. If this is done now, the
2027 man in the middle will get caught. Updated the protocol
2030 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2032 * Better installation directory handling. Configure module
2033 paths and other paths automatically to example_silc* files
2034 in doc/. A patch by toma.
2036 * Fixed compiler warning from MPI library, and from SILC RNG.
2039 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2040 It can be configured with ./configure. A patch by toma.
2042 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2044 * Find correct make to use in prepare-clean. A patch by
2045 toma. Affected file prepare-clean.
2047 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2049 * Added irssi variables use_auto_addr, auto_bind_ip,
2050 auto_bind_port and auto_public_ip.
2052 * Changed the interface for silc_client_send_key_agreement
2053 in lib/silcclient/silcapi.h
2057 irssi/src/silc/core/silc-core.c
2059 lib/silcclient/silcapi.h
2060 irssi/src/silc/core/silc-channels.c
2061 lib/silcclient/client_keyagr.c
2064 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2066 * Added silc_pkcs_public_key_compare to compare two
2067 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2069 * Check that the client who set the founder mode on the
2070 channel is the same client that is giving the founder
2071 mode to itself. It is done by comparing the saved public
2072 key (it is saved even in the authentication is passphrase).
2073 Affected file silcd/command.c.
2075 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2077 * Do not process packet for disconnected socket connection.
2078 Affected file lib/silccore/silcpacket.c.
2080 * Process the DISCONNECT packet through scheduler in the
2081 client library. Affected file lib/silcclient/client.c.
2083 * Fixed the silc_client_packet_parse to not to increase
2084 the packet sequence number if the conn->sock and the
2085 current socket connection is not same. This can happen
2086 for example during key agreement when the conn includes
2087 multiple socket connections (listeners). Affected file
2088 lib/silcclient/client.c.
2090 * The sender of the file transfer request now provides also
2091 the pointer (listener) for the key exchange protocol. If
2092 the listener cannot be created then it sends empty key
2093 agreement and lets the receiver provide the listener.
2095 Added `local_ip' and `local_port' arguments to the
2096 silc_client_file_send. If they are provided they are used,
2097 if not then it will attempt to find local IP address, if
2098 not found or bind fails then the remote client will provide
2101 Affected files are lib/silcclient/client_ftp.c and
2102 lib/silcclient/silcapi.h.
2104 * Extended the FILE SEND command to support defining the
2105 local IP and port for key exchange listener. They are
2106 optional. Affected file irssi/src/silc/core/silc-servers.c.
2108 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2110 * Defined to WHOIS command reply the sending of fingerprint
2111 of the client's public key (if the proof of posession of the
2112 corresponding private key is verified by the server).
2113 Updated to the protocol specification.
2115 * Added support of receiving the client's public key's
2116 fingerprint in command reply in client library. Affected
2117 file is lib/silcclient/command_reply.c, and
2118 lib/silcclient/idlist.[ch].
2120 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2122 * Do not send over 128 chars long nickname to the server
2123 in NICK command. Affected file lib/silcclient/command.c.
2125 * Do not send over 256 chars long channel names to the server
2126 in JOIN command. Affected file lib/silcclient/command.c.
2128 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2130 * Assure that silc_server_close_connection cannot be called
2131 twice for same socket context. Affected file is

2177 preserve the WHOWAS info for the client. Affected file
2178 silcd/server_util.c.
2180 * Fixed SERVER_SIGNOFF notify handling in the server. The
2181 server is now able to process incoming SERVER_SIGNOFF notify
2182 for a server that it doesn't even know about. It will remove
2183 the clients provided in the notify. Affected file
2184 silcd/packet_receive.c.
2186 * Check for partial packet in data queue after every packet that
2187 was found from the queue. Return and wait for more data if
2188 there is partial data in queue. Affected file is
2189 lib/silccore/silcpacket.c.
2191 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>

2206 irssi/src/fe-common/silc/module-formats.[ch].
2208 * Wrote a help file for FILE command.
2210 * Added silc_rng_global_get_byte_fast to get not-so-secure
2211 random data as fast as possible. Random data is read from
2212 /dev/urandom if available and from the SILC RNG if not
2213 available. It is used in padding generation. Affected file
2214 lib/silccrypt/silcrng.[ch].
2216 * All packets in client library are now processed synchronously.
2217 Optimized packet processing a lot. Affected file
2218 lib/silcclient/client.c.

2229 * Assure that silc_client_notify_by_server_resolve does not
2230 resolve the client information multiple times. If it cannot
2231 be found by the first it cannot be found at all. Affected
2232 file lib/silcclient/client_notify.c.
2234 * Fixed WHOWAS command reply calling. Affected file
2235 lib/silcclient/command_reply.c.
2237 * Removed all references to silc_idlist_get_client from the
2238 Irssi SILC client since that call is internal call used by
2239 the library. The Irssi SILC client will use now client
2240 retrieval functions found in silcapi.h.
2242 * Fixed a bug in resolving nickname info before sending
2243 private message. It used freed memory. Affected file
2244 irssi/src/silc/core/silc-servers.c.
2246 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2248 * Assure my_channels statistics cannot go negative in server.
2249 Affected files silcd/server.c, silcd/server_util.c.

2265 * Added silc_net_localip to return local host's IP address.
2266 Affected file lib/silcutil/silcnet.[ch].
2268 * If key exchange or rekey protocol is active for a connection
2269 parse all packets syncronously since there might be packets
2270 in packet queue that we are not able to process without first
2271 processing packets before them. Affected file silcd/server,
2272 lib/silcclient/client.c.
2274 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2275 whether library should continue processing the packet.
2276 Affected file lib/silccore/silcpacket.h.

2322 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2323 is incomplete and is being resolved, it won't be resolved
2326 Make sure also that USERS command reply does not resolve
2327 twice information. Affected file is
2328 lib/silcclient/command_reply.c.
2330 Make sure that silc_client_get_clients_by_list does not
2331 resolve twice same information.
2333 * Check for valid client->id in the silc_server_free_client_data.
2334 Affected file silcd/server.c.
2336 * Fixed /GETKEY nick@server not to crash if the server entry
2337 is not found. Affected file lib/silcclient/command.c.
2339 * Fixed the silc_server_check_cmode_rights to check the

2347 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2349 * Call the silc_server_udpate_servers_by_server in the
2350 primary router that comes back online in the backup resuming
2351 protocol. Otherwise it routes packets wrong. Affected file
2352 silcd/server_util.[ch], silcd/server_backup.c.
2354 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2356 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2357 lib/silcutil/silcbuffmt.[ch].
2359 * Redefined the SILC packet header to include the padding
2360 length. Affected file lib/silccore/silcpacket.[ch].
2362 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2363 length for maximum padding up to 128 bytes). Affected
2364 file lib/silccore/silcpacket.h.
2366 * Removed all backwards support for old 0.5.x MAC thingies.
2367 The SILC packet header change makes it impossible to be
2368 backwards compatible.
2370 * Send the ENDING packet with timeout in the backup resuming
2371 protocol. This is to assure that all routers has connected
2372 to the primary router. Affected file silcd/server_backup.c.
2374 * Changed the RNG to take the first IV from random data. It
2375 used to take it from zero actually. Changed the RNG also
2376 to use /dev/urandom during session. /dev/random is used
2377 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2379 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2381 * Changed the SILC packet header to have the first two bytes
2382 (the packet length) encrypted. Affected files aroung the
2383 code tree, lib/silccore/silcpacket.[ch]. Removed the
2384 SilcPacketCheckDecrypt callback. It is not needed anymore
2385 since the silc_packet_receive_process will determine now
2386 whether the packet is normal or special.
2388 * Implemented the unidirectional MAC keys. Affected files
2389 lib/silcske/silcske.c, silcd/protocol.c and
2390 lib/silcclient/protocol.c.
2392 * Implemented the packet sequence number to the MAC computation.
2393 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2394 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2395 lib/silcclient/protocol.c.
2397 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Allow backup router to announce servers. All servers
2400 announced by backup router are added to the global list
2401 automatically. Update hte server's socket to our primary
2402 router also when backup router announces a server.
2403 Affected file silcd/packet_receive.c.
2405 * Do not update the client->router in the function
2406 silc_server_udpate_clients_by_server if the client is on
2407 global list. We might fail to find any specific server
2408 for locally connected clients and local cell clients. They
2409 should still use the `from' and not `to' as client->router.
2410 This fixes backup router resuming protocol. Affected file
2411 silcd/server_util.c.
2413 * Decrease channel statistics count only if the channel
2414 deletion worked. Affected files are silcd/server.c and
2415 silcd/server_util.c.
2417 * Added silc_server_update_servers_by_server to update origin
2418 of all server entries. Used during backup router protocol.
2419 Affected files silcd/server_util.[ch], silcd/server.c. and
2420 silcd/backup_router.c.
2422 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2423 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2424 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2425 lib/silccrypt/silchmac.c.
2427 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2429 * Assure that router cannot reroute the same channel message
2430 to the sender. Affected file silcd/packet_receive.c.
2432 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2434 * Made better checks that the channel message is not sent
2435 to the router it came from. Affected file is
2436 silcd/packet_send.c. Fixed memory leak too.
2438 * Announce informations for incoming router connection, but
2439 only after checking if it is replaced by backup router.
2440 Affected file silcd/packet_receive.c.
2442 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2444 * Fixed the backup resuming protocol to work in multiple
2445 router environment. Affected file silcd/server_backup.c.
2447 * Route packet only to one router in the function
2448 silc_server_packet_send_to_channel. Affected file is
2449 silcd/packet_send.c.
2451 * Fixed silc_server_send_notify_dest to set the broadcast
2452 flag. Fixed the silc_server_send_notify_topic to actually
2453 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2454 Affected file silcd/packet_send.c.
2456 * Changed the SFTP Filesystem interface. Changed the
2457 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2458 the filesystem operation function. The SilcSFTPFilesystem
2459 is now a context that is allocated by all filesystem allocation
2460 functions and it already includes the operations structure
2461 and filesystem specific context. It is given as argument
2462 now to the silc_sftp_server_start. This made the interface
2463 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2464 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2466 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2468 * Changed the backup router adding and getting interfaces
2469 in the server. The router that will be replaced by the
2470 specified backup router is now sent as argument. Affected
2471 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2474 * Added silc_net_addr2bin_ne to return the binary form of
2475 the IP address in network byte order. Affected files
2476 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2478 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2480 * Check for existing server ID in silc_server_new_server
2481 and in silc_server_connect_to_router_final and remove the
2482 old entry if it exists. Affected file silcd/packet_receive.c,
2485 * Send the channel message always to only one router, either
2486 in upstream or downstream. Affected file is
2487 silcd/packet_send.c.
2489 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2491 * Wrote the definition of the backup resuming protocol to the
2492 protocol specification.
2494 * Removed one redundant channel key generation from normal
2495 server during joining procedure. Removed one redundant
2496 channel key sending from server to router during joining
2497 procedure. Affected file silcd/command.c.
2499 * Made minor bugfixes to the backup router resuming protocol.
2500 Affected file silcd/server_backup.c, server.c.
2502 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2504 * Added --disable-asm configuration option. Affected files
2505 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2508 * Implemented the backup resuming protocol that is used to
2509 resume the primary router position in the cell after the
2510 primary router comes back online. Affected files
2511 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2512 and silcd/server_util.[ch].
2514 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2516 * Sleep two (2) seconds after sending QUIT command to server.
2517 Affected file lib/silcclient/command.c.
2519 * Assure that if outgoing data buffer is pending do not force
2520 send any data. Affected file silcd/packet_send.c.
2522 * Assure that if outgoing data buffer is pending do not force
2523 send any data. Affected file lib/silcclient/client.c.
2525 * Implemented the backup router support when the primary router
2526 goes down. The servers and routers can now use the backup
2527 router as new primary router without loosing connectivity.
2529 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2531 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2532 in the server to indicate disabled entry. All data read
2533 from the connection will be ignored and no data is sent
2534 for entry that is disabled. Affected files are
2535 silcd/idlist.h, silcd/server.c.
2537 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2539 * Created SFTP client and server test programs in the
2540 lib/silcsftp/tests directory.
2542 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2544 * Implemented memory filesystem (virtual filesystem) for
2545 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2548 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2550 * Implemented the SFTP (SSH File Transfer Protocol) to the
2551 lib/silcsftp. It includes SFTP client and SFTP server
2554 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2556 * Moved lib/silccore/silcprotocol.[ch] to the
2557 lib/silcutil library.
2559 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2560 take variable argument list pointer as argument. Affected
2561 file lib/silcutil/silcbuffmt.[ch].
2563 * Added silc_buffer_set function that is used to set data
2564 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2565 Affected file lib/silcutil/silcbuffer.h.
2567 * Changed various routines in the core library to use the new
2568 silc_buffer_set instead of allocating new buffer only for
2571 * Added 64-bit value formatting and unformatting support to the
2572 silc_buffer_[un]format routines. Affected file is
2573 lib/silcutil/silcbuffmt.[ch].
2575 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2576 to includes/bitmove.h.
2578 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2580 * Fixed channel user mode saving in client library. Affected
2581 file lib/silcclient/command[_reply].c.
2583 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2585 * Defined the file transfer to the SILC Protocol. Added
2586 new packet type SILC_PACKET_FTP and defined File Transfer
2587 Payload. The mandatory file transfer protocol is SFTP
2588 (SSH File Transfer Protocol). Affected file in addition
2589 of the internet draft is lib/silccore/silcpacket.h.
2591 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2592 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2593 is used as part of backup router protocol when the primary
2594 router of the cell is back online and wishes to resume
2595 the position as primary router.
2597 * Redefined the MAC generation keys in the protocol. The
2598 same key is not used anymore in both direction. Both
2599 direction will now use different keys for sending and
2600 receiving. This fixes a potential security flaw. This
2601 change causes incompatibilities in the protocol.
2603 * Redefined also the MAC computation from the packet.
2604 An packet sequence number is now added to the MAC
2605 computation. This prevents possible replay attacks against
2606 the protocol. This change too causes incompatibilities
2609 Added `sequence' field to the SilcPacketContext to hold
2610 the current sequence number for the packet.
2612 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2614 * Added `created' field to the SilcIDListData in the file
2615 silcd/idlist.h to indicate the time when the entry was
2618 * Added `created' field to the SilcChannelEntry too. Affected
2619 file silcd/idlist.h.
2621 * Added `creation_time' aguments to all the announcement functions
2622 in the server. If it is provided then only the entries that
2623 was created after the provided time frame are actually
2624 announced. Affected file silcd/server.[ch].
2626 * The protocol says that the Channel ID's IP address must be
2627 based on the router's IP address. Added check for this in
2628 the silc_server_new_channel when processing incoming New Channel
2629 Payload. Affected file silcd/packet_receive.c.
2631 * Print out the correct version with --version in SILC client.
2632 Affected file irssi/src/silc/core/silc-core.c.
2634 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2636 * Fixed WHOWAS command to check for completnes of the client
2637 entry always, not just when the command is coming from client.
2638 Affected file silcd/command.c.
2640 * Added new function silc_server_packet_queue_purge to purge the
2641 outgoing data queue to the network. After the function returns
2642 it is guaranteed that the outgoing packet queue is empty.
2643 Affected file silcd/packet_send.[ch].
2645 * Purge the outgoing packet queue in the rekey protocol's final
2646 callback to assure that all rekey packets go to the network
2647 before quitting the protocol. Affected file silcd/server.c.
2649 * Added silc_client_packet_queue_parse as similar function as
2650 in server to the client library. The affected file is
2651 lib/silcclient/client.c.
2653 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2655 * Splitted silcd/server.c and created silcd/server_util.[ch]
2656 for utility functions.
2658 * Added new socket flag SILC_SF_DISABLED to indicate that the
2659 connection is open but nothing can be sent to or received from
2660 the connection. Affected file lib/silcutil/silsockconn.[ch].
2661 The checking for disabled socket is checked in the low level
2662 silc_socket_write and silc_socket_read functions.
2664 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2666 * Allow only nicknames and channel names that fits into the
2667 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2669 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2671 * When processing JOIN command reply in server check that if
2672 the channel exists in our global list we'll move it the local
2673 list. Affected file silcd/command_reply.c.
2675 * Fixed the check whether client is joined on the channel already
2676 in JOIN command. Affected file lib/silcclient/command.c.
2678 * Fixed the JOIN command reply to check whether the channel
2679 already exists. Affected file lib/silcclient/command_reply.c.
2681 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2683 * Added silc_ske_status_string to map the SKE error numbers
2684 to readable strings. The affected files are
2685 lib/silcske/silcske[_status].[ch].
2687 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2689 * Do not show the private channels on the WHOIS channel list
2690 as it is not allowed by the protocol. The affected file is
2693 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2695 * Assure that the packet length digged from the actual packet
2696 is something sensible in the silc_packet_decrypt_rest_special
2697 in lib/silccrypt/silcpacket.c.
2699 * Free and NULL the allocated pointer in silc_hmac_alloc if
2700 the HMAC allocation fails. The affected file is
2701 lib/silccrypt/silchmac.c.
2703 * Print the selected security properties to the log files in
2704 the server. Affected file silcd/protocol.c.
2706 * Add SKE's reference counter even if calling the completion
2707 callback manually. Otherwise it goes negative, although it
2708 does not cause any problems. The affected file is
2709 lib/silcske/silcske.c.
2711 * Remove the client entry with short timeout after giving the
2712 KILL command. Affected file lib/silcclient/command.c.
2714 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2715 case all found clients are already disconnected (WHOWAS would
2716 found them) in the server. Affected file silcd/command.c.
2718 * Update the last_receive (time of last data received) to be
2719 updated only when received private or channel message so that
2720 the idle time showed in WHOIS makes more sense.
2722 * Added boolean field `valid' in to the SilcClientEntry in the
2723 client library to indicate whether the entry is valid or not.
2724 This fixes the nickname change bug on channel when changing
2725 the nickname to be same than the old (like nick to Nick) the
2726 nickname formatter doesn't set the new nick anymore to Nick@host.
2727 Affected file lib/silcclient/idlist.[ch].
2729 * Now actually fixed the nickname changing on disconnection.
2730 Added new function silc_change_nick to the Irssi SILC Client.
2731 Affected file irssi/src/silc/core/client_ops.c,
2732 irssi/src/silc/core/silc-nicklist.[ch].
2734 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2736 * Check that the public key exists in the GETKEY command before
2737 trying to encode it. Affected file silcd/command.c.
2739 * Print some notifications on received public keys with GETKEY
2740 command in the Irssi SILC Client. Affected files are
2741 irssi/src/fe-common/silc/module-formats.[ch],
2742 irssi/src/silc/core/client_ops.c.
2744 * Use IDENTIFY command to resolve the server information in the
2745 GETKEY command instead of INFO command. Affected file
2746 lib/silcclient/command.c.
2748 * All command reply functions in the client library now calls
2749 the pending command reply callbacks even if an error has
2750 occurred. The server has done this a long time and now it was
2751 time to move the client library to this as well. Now all
2752 errors can be delivered back to the pending command reply
2753 callbacks if necessary. Affected files are
2754 lib/silcclient/command[_reply].[ch].
2756 * Change the nickname on disconnection back to the username
2757 because in reconnect the server will enforce it to it anyway.
2758 Affected file irssi/src/silc/core/silc-servers.c.
2760 * Fixed a config file parsing bug in the Irssi SILC client.
2761 Affected file irssi/src/silc/core/clientconfig.c.
2763 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2765 * When printing the channel mode on JOIN, verify that the
2766 channel key and channel's HMAC are valid. Affected file
2767 irssi/src/silc/core/client_ops.c.
2769 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2771 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2772 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2773 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2775 * Removed channel key rekey task deleting from the function
2776 silc_server_save_channel_key. Affected file silcd/server.c.
2777 Added explicit timeout task context instead that is used to
2778 delete the task if we are registering a new task before the
2779 new task has elapsed.
2781 * When channel key rekey occurs the client library now saves
2782 the old channel key for a short period of time (10 seconds) and
2783 is able to use it in case some is still sending channel
2784 messages encrypted with the old key after the rekey. Affected
2785 file lib/silcclient/[idlist.h|client_channel.c].
2787 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2789 * Added check to the silc_server_new_id_real to not accept
2790 new ID if it is the sender's own ID. Affected file is
2791 silcd/packet_receive.c.
2793 * Assure that we do not announce ourself or the one we've
2794 sending our announcements when we're router and are announcing
2795 servers to our primary router. Affected file silcd/server.c.
2797 * Fixed silc_server_command_identify_check_client to assemble
2798 correct WHOIS packet. It send corrupted WHOIS packet and
2799 caused problem with router to router connections. Affected
2800 file silcd/command.c.
2802 Fixed also silc_server_command_whois_check the same way
2803 as for the IDENTIFY command.
2805 * Added new SilcIDListStatus to the server in the SilcIDListData
2806 structure. The status now includes the current status of
2807 the entry (like registered, resolved etc.). Affected file
2808 silcd/idlist.[ch]. Defined a bunch of different status types
2809 as well. This replaced the old boolean registered field as well.
2811 Added resolve_cmd_ident field to the SilcClientEntry structure
2812 too so that if the entry is for example being resolved so
2813 another command may attach to the same pending command reply
2814 without requiring to resolve the same entry again. This concept
2815 should optimize the WHOIS and the IDENTIFY resolving under
2816 heavy load by taking away unnecessary resolving for entries
2817 that are being resolved already.
2819 Added support for adding multiple pending commands for one
2820 command idenfier. Affected file silcd/command[_reply].[ch].
2822 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2823 before deleting the data. Otherwise the hash table will have
2824 freed data in comparison functions. Affected file is
2825 silcd/command_reply.c.
2827 * Fixed silc_idlist_replace_client_id to add the new entry to
2828 the cache with NULL nickname. Otherwise there will be invalid
2829 memory as the nickname after the nickname is freed. Affected
2830 file silcd/packet_receive.c.
2832 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2833 saved into wrong slots because the previous number of entries
2834 was not taken into account. Affected file silcd/idlist.c.
2835 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2837 * If we are router and we receive JOIN notify to a channel that
2838 does not have any users then notified client is marked as the
2839 channel founder, as it is it. The affected file is
2840 silcd/packet_receive.c
2842 * Added to the extended hash table API's table_del_*ext functions
2843 the destructor as argument too, so that the caller can decide
2844 which destructor to use or whether to use destructor at all.
2845 Affected file lib/silcutil/silchashtable.[ch].
2847 * Fixed ID Cache purging. It actually deleted the entries from
2848 the hash table after the data was freed. The hash table ended
2849 up comparing freed memory. The affected file is
2850 lib/silccore/silcidcache.c.
2852 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2854 * Fixed Irssi SILC client's KILL command's HELP syntax.
2856 * The USERS command now resolves the detailed user information
2857 if the userinfo field is missing. Affected file is
2858 lib/silcclient/command_reply.c.
2860 * Do not print error in silc_file_read if the read file does
2861 not exist. Just silently return NULL. Affected file is
2862 lib/silcutil/silcutil.c.
2864 * Fixed the silc_log_output to not wine about NULL filename
2865 and to not create some bogus " " filename. Affected file is
2866 lib/silcutil/silclog.c.
2868 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Fixed various printing bugs on the user interface in the
2871 Irssi SILC Client. Minor changes that were forgotten from
2874 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2876 * Fixed the configure.in.pre and the compilation and distribution
2877 environment to support the new autoconf 2.52. That version is
2878 now required to compile the CVS trunk.
2880 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2883 to generally parse user@fqdn format strings. Affected file
2884 lib/silcutil/silcutil.c.
2886 * Added nickname_format and nickname_force_format fields to the
2887 SilcClientParams structure. The first one defines the format
2888 for the nicknames that the library will enforce if the receives
2889 multiple same nicknames. The second one is boolean value and
2890 can be used to force the library to always enforce the format
2891 to the nicknames regardles whether there are multiple nicknames
2892 or not. This configurable formatting was employed to flexibly
2893 support accessing multiple nicknames from the user interface.
2894 The userinterface can now set the nicknames to what ever format
2895 they prefer. Affected file lib/silcclient/silcapi.h.
2897 Added function silc_client_nickname_format to the file
2898 lib/silcclient/idlist.c. It performs the nickname formatting.
2900 Added new field `hostname´ to the SilcClientEntry context.
2901 It holds the hostname of the client. Affected file is
2902 lib/silcclient/idlist.h.
2904 * Irssi SILC Client sets the nicknames in nick@hostn format.
2905 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2906 irssi/src/silc/core/silc-core.c.
2908 The WHOIS printing now also shows both the real nickname and
2909 the formatted nickname so that user knows how to access the
2910 user if there are multiple same nicknames cached. Affected
2911 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2912 printing formatting too to take the hostname now as a separate
2913 argument. The Affected file is
2914 irssi/src/fe-common/silc/modules-formats.[ch].
2916 * Changed the silc_client_get_clients_local to accept the formatted
2917 nickname as argument. It accepts the real nickname too but the
2918 formatted nickname can be used to find the true entry from
2919 multiple entries. Affected file lib/silcclient/silcapi.h and
2920 lib/silcclient/idlist.c.
2922 * Added nickname_format_parse field to the SilcClientParams.
2923 It is a callback function provided by the application to parse
2924 the nickname out of the formatted nickname string. The library
2925 calls it to get the nickname from the formatted string. Since
2926 the application generally knows better the format of the nickname
2927 string it parses it instead of the library, even though library
2928 encodes the formatted string. If the callback function is not
2929 provided then the library will use the string as is. The
2930 affected file is lib/silcclient/silcapi.h.
2932 * All the nickname strings passed to the client library in
2933 commands are now expected to be formatted nickname strings.
2934 If the command does not support the formatted nickname string
2935 it will assume that the sent string is the actual nickname.
2936 Affected file lib/silcclient/command.c.
2938 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2940 * Added public key authentication support to OPER and SILCOPER
2941 commands in the client library. Affected file is
2942 lib/silcclient/command.c.
2944 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2946 * Changed the get_auth_methdod client operation to be asynchronous.
2947 It can be async if the application resolves the authentication
2948 method from the server during the negotiation. Added new
2949 SilcGetAuthMeth completion callback that the application will
2950 call after resolving the authentication method.
2952 Added function silc_client_request_authentication_method that
2953 the application can use to resolve the authentication method
2954 from the server. Added also SilcConnectionAuthRequest callback
2955 that the library will call after the server has replied. The
2956 application can call this function if it does not know the
2957 current authentication method.
2959 Affected files are lib/silcclient/client.c and
2960 lib/silcclient/silcapi.h.
2962 * The Irssi SILC client now automatically resolves the authentication
2963 method incase any configuration information is not present (and
2964 currently there never is). The affected file is
2965 irssi/src/silc/core/client_ops.c.
2967 * Fixed public key authentication from the client library.
2968 Affected file lib/silcclient/protocol.c. Changed also the
2969 protocol specification about the public key authentication in
2970 the connection authentication protocol. The actual data to be
2971 signed is now computed with a hash function before signing.
2973 * Fixed the public key authentication from the server as well.
2974 Affected file silcd/protocol.c.
2976 * Removed the mlock()'s from the memory allocation routines.
2977 Affected file lib/silcutil/silcmemory.c. The ./configure does
2978 not check anymore for the mlock(). Affected file is
2981 * Fixed USERS command in server to allow the execution of the
2982 command for private and secret channels if the client sending
2983 the command is on the channel. Affected file silcd/command.c.
2985 * Fixed silc_client_get_clients_local to return the clients
2986 count correctly. It could return wrong value. Affected file
2987 lib/silcclient/idlist.c.
2989 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2991 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2992 types. The assembler optimizations seemed not to like 64-bit
2993 data types. The assmebler optimizations thus are now enabled
2994 also for BSD systems as opposed to only enable them for Linux.
2996 * Do not check for threads at all on BSD systems. Affected
2997 file configure.in.pre.
2999 * Removed -n and -h options from the Irssi SILC Client since
3000 they are not used in silc.
3002 * Fixed the prime generation to assure that the first digit
3003 of the generated random number is not zero since our conversion
3004 routines does not like number strings that starts with zero
3005 digit. If zero digit is seen the random number is regenerated.
3006 This caused some corrupted RSA keys when the zero first digit
3007 was met. Affected file lib/silcmath/silcprimegen.c.
3009 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3011 * Fixed WIN32 configuration in the ./configure script.
3012 Fixed to include xti.h on environments that has it.
3013 Patches by Carsten Ilchmann and andrew.
3015 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3017 * Changed the silc_id_create_client_id to be collision
3018 resistant. It is now assured that there cannot be created
3019 two same client ID's. I suspect that some weird bugs in
3020 the server were actually caused by duplicate Client IDs.
3021 Affected file silcd/serverid.[ch]. A router receiving
3022 new ID now also assures and informs the sending server
3023 if the ID caused collision.
3025 * Changed the silc_id_create_channel_id to also assure that
3026 there are no collisions.
3028 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3030 * Statement about ignoring the Mutual Authentication flag when
3031 performing rekey with PFS was a bit misleading. It is ignored
3032 if it was set in the initial negotiation, it cannot be even
3033 set in the rekey. Fixed in the ke-auth draft. Started the
3034 new versions of the protocol drafts in the doc/.
3036 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3038 * Fixed a bug in silc_client_command_identify_save when saving
3039 new channel information. The channel name was no duplicated
3040 and caused crash on exit. Affected file is
3041 lib/silcclient/command_reply.c.
3043 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3045 * Fixed the getkey command handling in the server. Send just
3046 empty OK reply to the sender if the key could not be fetched
3047 (but everything else was ok, like the key just was not available).
3048 Changed the public key parameter to optional in the protocol
3049 specs so that empty OK reply can be sent. Affected file
3052 Added a message to Irssi SILC client to tell to user if the
3053 server did not return a public key.
3055 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * Fixed a channel key regeneration bug. It registered new
3058 timeout tasks exponentially until all system resources were
3059 used. Affected file silcd/server.c.
3061 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3063 * Added the SILC Document generator to the scripts/silcdoc.
3064 It can be used to generate the Toolkit Reference Manual out
3065 of the source tree. Internally it will also use the RoboDoc
3066 generator now imported in util/robodoc.
3068 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3070 * Added couple of return's in rekey protocol if error orccurred
3071 during the protocol. The execution must be terminated.
3072 Affected file silcd/protocol.c. Also, terminate the protocol
3073 always with timeout.
3075 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3077 * The client's Client ID was created initally from the wrong
3078 nickname (it could have been in format nick@host) in the
3079 silc_server_new_client. Affected file silcd/packet_receive.c
3081 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3083 * Added some SILC_LOG_ERROR's to various error conditions
3084 if client could not be added to ID cache. Affected files
3085 silcd/packet_receive.c and silcd/server.c.
3087 * When client's sock->user_data is freed, NULL also the
3088 client->router and client->connection pointers. Added check
3089 for these pointers being NULL to various places around the
3090 code. Affected file silcd/server.c.
3092 * Added client->data.registered == TRUE checks to various
3093 places around the code to assure that unregistered client's
3094 are not handled when it is not allowed. Affected file
3097 * Added `bool registered' fields to all
3098 silc_idlist_[server|client]_get_* routines to indicate whether
3099 the fetched client needs to be registered or not. Affected
3100 file silcd/idlist.[ch].
3102 * Add your own entry as registered to the ID cache in the
3103 server. Affected file server.c.
3105 * Fixed a bug in silc_server_new_server. The SilcServer was
3106 set as the new server's context instead of SilcServerEntry.
3107 This naturally caused some weird bugs.
3109 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3111 * Do not delete the channel rekey task when adding it
3112 for in silc_server_create_channel_key.
3114 * Changed the silc_server_create_channel_key to return
3115 TRUE or FALSE to indicate the success of the channel key
3118 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3120 * Fixed MSVC++ project files and added missing files to
3121 Makefiles under win32/.
3123 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3125 * Do not add TCP_NODELAY flag if the operating system
3126 does not have it defined. Affected files are
3127 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3129 * Fixed buffer overflow from Irssi SILC Client. Affected
3130 file irssi/src/fe-common/core/themes.c.
3132 * Fixed double free in client library in the file
3133 lib/silcclient/client.c when disconnecting from server.
3135 * Applied double free patch from cras to Irssi SILC client.
3136 Affected files irssi/src/core/[modules/expandos].c
3138 * Fixed the disconnection handling to Irssi SILC Client.
3139 The application must call silc_client_close_connection
3140 in ops->connect client operation in case of failure of
3141 the connection. Affected file is
3142 irssi/src/silc/core/client_ops.c.
3144 * Do not set sock->protocol to NULL in the function
3145 silc_client_close_connection after executing the protocol's
3146 final callback since the sock might not be valid anymore.
3147 Affected file lib/silcclient/client.c.
3149 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3151 * Do not enable SILC_THREADS if the linking with libpthread
3152 did not happen. Affected file configure.in.pre.
3154 * Added notion to protocol specification that server must
3155 verify the sent authentication payload with CMODE when
3156 setting the channel founder key. Implemented it to the
3157 server. Affected file silcd/command.c.
3159 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3161 * Added _EXTRA_DIST SILC distribution variable to the
3162 distributions file. It is used to conditionally add extra
3163 files or directories to the specific distribution. Affected
3164 files ./prepare, Makefile.am.pre and distributions.
3166 Removed the `_' from the start of the distribution names.
3169 * Added README.WIN32 for instructions to compile the Toolkit
3172 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3174 * Fixed a double free in disconnection in the server. Affected
3175 file is silcd/server.c.
3177 * Fixed the lib/silcske/groups.c to work now also with GMP
3178 MP library. The string conversion did not work when using
3179 specific base and the base is indicated in the string as well.
3181 * Created win32/ directory which now includes MSVC++ specific
3182 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3183 It will appear only in the toolkit distribution
3185 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3187 * Changed the key material distribution function in case when
3188 the hash output is too short. The data is now concatenated
3189 a bit differently than it used to. Made the change to the
3190 SKE protocol specification.
3192 * Added better GMP detection to configure.in.pre. A patch
3195 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3197 * Fixed a minor bug in SKE that might cause some problem on
3198 some platforms. Affected file lib/silcske/silcske.c.
3200 * Added the cookie checking for initiator in the SKE. It checks
3201 that the responder returns the sent cookie unmodified. The
3202 affected file is lib/silcske/silcske.c. Added new SKE
3203 error type INVALID_COOKIE that can be sent during the
3204 negotiation. Fixed some memory leaks as well.
3206 * Added the "invalid cookie" error message to Irssi SILC client's
3209 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3211 * Added `task_max' field to the SilcClientParams to indicate
3212 the maximum tasks the scheduler can handle. If set to zero,
3213 default values are used. Affected file lib/silcclient/silcapi.h.
3215 * Fixed memory leaks in silc_client_close_connection. Affected
3216 file lib/silcclient/client.c.
3218 * Added silc_client_del_client_entry to client library to free
3219 all memory of given client entry. Affected file is
3220 lib/silcclient/idlist.[ch].
3222 * Added new functions silc_client_del_channel and
3223 silc_client_del_server to delete channel and server entries.
3224 Affected file lib/silcclient/[silcapi.h/idlist.c].
3226 * Removed silc_client_del_client_by_id from silcapi.h.
3228 * Fixed the INFO command to return the server's own info
3229 correctly when querying by Server ID. Affected file is
3232 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3234 * Removed the non-blocking settings in WIN32 code in the
3235 silc_sock_[read/write] and added SleepEx instead. Affected
3236 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3237 of input data is now checked with FIONREAD and ioctlsocket.
3239 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3241 * Call silc_schedule_task_del_by_context in the
3242 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3243 Affected file lib/silccore/silcprotocol.c.
3245 * Call silc_protocol_cancel for active protocols in the
3246 silc_server_close_connection if the funtion
3247 silc_server_free_sock_user_data has not been called.
3248 Affected file silcd/server.c.
3250 * Generic tasks cannot be deleted using the del_by_fd
3251 task deleting function since generic tasks does not match
3252 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3254 * Added a notion to SILCOPER help file that the SILCOPER works
3255 only on router server, not on normal server.
3257 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3259 * Added for WIN32 support for the new scheduler as well.
3260 Affected file lib/silcutil/win32/silcwin32schedule.c.
3262 * Fixed the SHA1 implementation to work on various platforms.
3264 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3266 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3267 API. It is part of the scheduler now. Everything else is
3268 as previously but some functions has changed their names.
3269 Checkout the lib/silcutil/silcschedule.h for the interface.
3270 Updated all applications to use the new interface. Affected
3271 files are lib/silcutil/silcschedule.[ch].
3273 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3275 * Found a bug in the SKE implementation. The HASH value,
3276 specified by the protocol, was not computed correctly. The
3277 public key of the responder was not added to the computation
3278 even though it is mandatory. Affected file lib/silcske/silcske.c.
3279 This unfortunately causes incompatibilities with older
3280 clients and servers.
3282 * Added WIN32 specific network init and uninit functions:
3283 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3284 the Winsock2. Affected file lib/silcutil/silcnet.h and
3285 lib/silcutil/win32/silcwin32net.c.
3287 * Set the socket always to nonblocking mode on WIN32 after
3288 reading data or writing data. Affected file is
3289 lib/silcutil/win32/silcwin32sockconn.c.
3291 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3293 * Fixed various compilation problems under WIN32. Affected
3294 files lib/silcutil/win32/silcwin32thread.c and
3295 lib/silcutil/win32/silcwin32schedule.c.
3297 * Removed all _internal.h #includes from public header
3298 files. Internal headers must never be included from
3301 Removed also the lib/silcske/payload_internal.h file.
3303 * All include files that may be needed (public and some others
3304 included by the public headers) by application developers are
3305 now copied to the ./includes directory. It does not copy any
3306 internal headers. Affected file Makefile.defines.pre and all
3307 Makefile.am's under lib/ and subdirs.
3309 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3311 * Do not change the ~/.silc directory's permissions automatically.
3312 Affected file irssi/src/silc/core/clientutil.c.
3314 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3316 * Do not cancel the protocol in silc_server_close_connection
3317 it might cause recursion. Now cancelled in the function
3318 silc_server_free_sock_user_data. Affected file silcd/server.c.
3320 * Fixed the silc_server_remove_clients_by_server to regenerate
3321 the channel keys correctly finally. Added also new function
3322 silc_server_remove_clients_channels to actually do it.
3323 Affected file silcd/server.c.
3325 * Fixed the silc_server_new_channel to not crash by giving
3326 wrong router to the new channel. Affected file is
3327 silcd/packet_receive.c.
3329 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3331 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3332 which is given as argument to the silc_client_alloc now.
3333 It can be used to configure the client and set various parameters
3334 that affect the function of the client.
3336 * The USERS command in server did not check whether the channel
3337 is private or secret. Affected file silcd/command.c.
3339 * Added new argument to the USERS command in protocol specification.
3340 The USERS command now can take the channel name as argument
3341 as well. Added support for this in client and server and
3342 updated the protocol specs.
3344 * Completed the GETKEY command in client. It can be now used
3345 to fetch also servers public key not only some clients.
3346 Affected files lib/silcclient/command[_reply].c.
3348 * Added silc_client_get_server to return server entry by the
3349 server name. Affected files lib/silcclient/silcapi.h and
3352 * Redefined the IDENTIFY command in protocol specification to be
3353 more generic. It now can be used to query information about
3354 any entity in the SILC Network, including clients, servers and
3355 channels. The query may be based either the entity's name
3356 or the ID. Added support for this in both client and server.
3358 Affected files silcd/command.c and lib/silcclient/command.c
3359 and command_reply.c.
3361 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3362 the _from_client and _from_server functions. Affected file
3365 * Added silc_client_get_channel_by_id_resolve to the file
3366 lib/silcclient/silcapi.h to resolve channel information by
3367 its ID. Added also silc_client_get_channel_by_id that
3368 does not resolve it from the server.
3370 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3372 * Added SilcServerEntry context into the client library
3373 to represent one server. The INFO command now allocates
3374 these to save the resolved server info. For now on the
3375 client library will also keep information about servers,
3376 connected and resolved with INFO.
3378 The INFO command now allocates the SilcServerEntry context
3379 and saves the server info there. The COMMAND_REPLY in
3380 the INFO now returns the parameters to application in
3381 same order as defined in the protocol specification.
3383 The entries are cached in the client->server_cache.
3385 * The INFO command is now issued after received the Client ID
3386 from the server. Affected file lib/silcclient/client.c.
3388 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3389 to the application as the mode changer might be server.
3390 It is guaranteed that NULL is not returned anymore to the
3391 application. Affected file lib/silcclient/client_notify.c.
3393 The ID Type is now also passed to the application so that
3394 it can check whether the returned entry is SilcClientEntry
3397 Added new function silc_client_get_server_by_id to return
3398 the server entry by ID. Affected files are the
3399 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3401 * Do not create the channel in the Irssi SILC Client when issuing
3402 the JOIN command but when received the sucessful JOIN command
3403 reply. Otherwise the channel might get created even though we
3404 could not join it. The Affected file is
3405 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3407 * Fixed a channel joining bug in router. The router must also
3408 check the channel modes, invite and ban lists etc. when serving
3409 the JOIN command sent by normal server. Affected file is
3410 silcd/command.c. The router now resolves the client's
3411 information from the server who sent the JOIN command if it
3412 does not know it, and processes the JOIN command only after
3415 * Changed the SilcCommandCb to take new argument; void *context2.
3416 Affected file lib/silccore/silccommand.h
3418 The second argument in the command callbacks in the server now
3419 includes the SilcServerCommandReplyContext if the command was
3420 called as pending command callback from the command reply.
3421 Otherwise it is NULL. When called as pending the status of the
3422 command reply will be checked and if it was erronous the
3423 error will be sent to the original sender of the command.
3424 This way the client always receives the error messages even
3425 though the server was actually the one who received the error
3426 when it resent the command to router, for example. Affected
3427 files silcd/command[_reply].[ch].
3429 * Fixed sending WHOWAS command's error message to client if
3430 the requested client could not be found. It was missing.
3433 * Changed the CMODE and CUMODE commands reply arguments in the
3434 protocol specification. The Channel ID is now sent in both
3435 of the commands to identify the channel. Implemented this
3436 new feature to the client and server. Affected files
3437 lib/silcclient/command_reply.c and silcd/command.c.
3439 * Made better checks for invite and ban lists in the JOIN
3440 command in server. Affected file silcd/command.c.
3442 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3444 * The server now performs the incoming host IP/DNS lookup
3445 using the silc_socket_host_lookup and thus does not block
3446 the server anymore. Affected file silcd/server.c.
3448 * Completed the multi-thread support for SILC Scheduler in
3449 the lib/silcutil/silcschedule.c.
3451 * Fixed the configure.in.pre to detect the pthread correctly
3454 * Fixed a deadlock in silc_task_queue_wakeup in the file
3455 lib/silcutil/silctask.c.
3457 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3459 * Added new function silc_schedule_wakeup that is used in
3460 multi-threaded environment to wakeup the main thread's
3461 schduler. It needs to be used when a thread adds a new task
3462 or removes a task from task queues. After waking up, the
3463 scheduler will detect the task queue changes. If threads
3464 support is not compiled in this function has no effect.
3465 Implemented the wakeup mechanism to both Unix and WIN32
3466 systems. Affected files are lib/silcutil/silcschedule.[ch],
3467 lib/silcutil/unix/silcunixschedule.c and the
3468 lib/silcutil/win32/silcwin32schedule.c.
3470 * Added new function silc_task_queue_wakeup to wakeup the
3471 scheduler by the specified task queue. Affected file
3472 lib/silcutil/silctask.[ch].
3474 * The silc_socket_host_lookup_start now wakes up the scheduler
3475 after adding the timeout task. Affected file is
3476 lib/silcutil/silcsockconn.c.
3478 * The silc_socket_host_lookup is synchronous now if the threads
3479 support is not compiled in. However, the callback is still
3480 called asyncronously through the scheduler, anyway. Affected
3481 file lib/silcutil/silcsockconn.c.
3483 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3485 * Added new function silc_socket_host_lookup to perform
3486 asynchronous IP and FQDN lookups for the socket connection.
3487 Affected files lib/silcutil/silcsockconn.[ch].
3489 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3491 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3492 that may or may not compile the mutex support in.
3494 Changed the silc_mutex_alloc interface. It allocates the
3495 mutex now to the sent pointer and returns TRUE or FALSE.
3497 Affected file lib/silcutil/silcmutex.h.
3499 * Wrote the SILC Task Queue interface to support multi-threads.
3500 Affected file lib/silcutil/silctask.[ch].
3502 * Wrote the SILC Scheduler to support multi-threads. Affected
3503 file lib/silcutil/silcschedule.c.
3505 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3507 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3508 in lib/silcutil/win32/.
3510 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3512 * Defined SILC Mutex API and SILC Thread API and implemented
3513 them for Unix. Affected files are
3514 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3515 lib/silcutil/unix/silcunixmutex.c and
3516 lib/silcutil/unix/silcunixthread.c.
3518 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3520 * Fixed the silc_server_remove_clients_by_server's channel
3521 key re-generation. The hash table handling was incorrect
3522 and would not work with many channels. Affected file is
3525 * Fixed some memory leaks around the server code.
3527 * Rewrote the silc_server_get_users_on_channel to support IPv6
3528 based Client ID's. Affected file silcd/server.c.
3530 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3531 specification. However, a separate document must be written
3532 to define the detailed signing procedure and the payload
3533 associated with the flag. Defined the flag to the
3534 lib/silccore/silcchannel.h as well.
3536 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3538 * Changed the dynamic tables to static size tables in the
3539 lib/silccrypt/silchmac.c.
3541 * Removed GCC dependencies from the code. A patch by cras.
3543 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3545 * Do not show the error "Error receiving packet bla bla"
3546 in server if it really was not an error (-2 means that reading
3547 is pending). Affected file silcd/server.c.
3549 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3551 * Fixed a possible crash in silc_server_remove_clients_by_server
3552 in silcd/server.c. Fixed there also some memory leaks.
3554 * Fixed the silc_idlist_replace_client_id. It could replace
3555 wrong key in the hash table. Affected file silcd/idlist.c.
3557 * Do not check whether there are global users on the channel
3558 if the channel->global_users is FALSE. Affected functions
3559 silc_server_remove_from_one_channel and
3560 silc_server_remove_from_channels in silcd/server.c. Also,
3561 do not check if the removed client is local as we can be
3562 sure that global client was not removed from the channel
3563 and checking for global users is not needed.
3565 * The silc_server_remove_clients_by_server now re-generates
3566 the channel keys correctly for those channels that had
3567 clients removed from them. Affected file silcd/server.c.
3569 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3571 * Found the reason of random crashes in the server. We weren't
3572 ignoring the SIGPIPE signal (which can be sent in write())
3573 and it crashed the server. Affected file silcd/silcd.c.
3575 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3577 * Assure that sock->user_data is not NULL in the function
3578 silc_server_packet_send in silcd/packet_send.c.
3580 * Disconnect the remote connection if it could not be added
3581 to any ID lists in the server. The affected file is
3584 * Check in silc_server_packet_send[_real/dest] that the
3585 socket is not disconnecting and ignore the data if it is.
3586 Affected file silcd/packet_send.c.
3588 * Define inline to __inline on native WIN32 compilation.
3589 Affected file includes/silcwin32.h.
3591 * Added some explicit type casts for inline code since MSVC
3592 require them. Affected files lib/silcutil/silcbuffer.h,
3593 lib/trq/silcdlist.h and lib/trq/silclist.h.
3595 * Print warning in log files from now on if the packet
3596 decryption fails. Affected file silcd/server.c.
3598 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3600 * Changed the `say' client operation's interface to accept
3601 new `type' argument to indicate the type of the message sent
3602 by the library. The application may filter the library's
3603 messages according the type. The affected file is the
3604 lib/silcclient/silcapi.h.
3606 * Added two new functions to lib/silcclient/silcapi.h:
3607 silc_client_del_client and silc_client_del_client_by_id.
3608 Affected file lib/silcclient/idlist.c.
3610 * Moved the clientincludes.h from includes/ to silc/ and
3611 serverincludes.h from includes/ to silcd/.
3613 * The modes for the CMODE and CUMODE are now passed as
3614 uint32 for application with COMMAND_REPLY. The affected
3615 file is lib/silcclient/command_reply.c.
3617 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3619 * /WHOIS without arguments shows client's own information.
3620 Affected file lib/silcclient/command.c.
3622 * Changed PING to not accept any arguments. The specs
3623 says that client can ping only the connected server so
3624 requiring an argument is not needed. Affected file is
3625 lib/silcclient/command.c.
3627 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3629 * Fixed a fatal bug in private message sending and reception
3630 encryption and decryption when using private message keys.
3631 The implementation was incorrect and did not follow the
3632 specification. It causd that some of the message were
3633 lost since it did not use the sending and receiving keys
3634 as the protocol suggests. This has been fixed and will cause
3635 incompatibilities with older clients when sending private
3636 message encrypted with private message keys. Affected files
3637 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3638 and various other in Irssi SILC Client.
3640 Added `responder' boolean argument to the functions
3641 silc_client_add_private_message_key[_ske] to indicate when
3642 the key is added as responder or initiator of the key
3645 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3647 * Removed the silc_ske_check_version function and created
3648 a SilcSKECheckVersion callback. Added also a function
3649 silc_ske_set_callbacks that is now used to set all SKE
3650 callbacks. The callback functions are not given to
3651 the SKE functions anymore, but this function is used to
3654 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3656 * Added `silc_version' argument to the silc_client_alloc
3657 to define the version of the application for the library.
3658 The library will use the version string to compare it
3659 against the remote host's (usually a server) version
3660 string. Affected file lib/silcclient/silcapi.h
3662 * Added the KE protocol context to Key Agreement context
3663 in client library so that we can abort the SKE if it
3664 is in process when we get timeout. Affected file is
3665 lib/silcclient/client_keyagr.c.
3667 * Do not resolve the client ID forever if it returns in the
3668 first time that such client does not exist. This was done
3669 for example with private message. Affected file is
3670 lib/silcclient/client_prvmsg.c.
3672 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3674 * Do not add regex.h for WIN32. The affected file
3675 includes/silcincludes.h.
3677 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3678 not work yet 100%. It generates the DLL's automatically
3679 when compiling with --with-win32 under cygwin.
3681 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3683 * lib/contrib/regex.c is not compiled on WIN32.
3685 * Added silc_net_get_socket_opt function to the
3686 lib/silcutil/silcnet.h.
3688 * Added includes/silcwin32.h for WIN32 specific includes
3691 * Do not use ptime structure or any of the posix process
3692 functions on WIN32 in lib/silccrypt/silrng.c.
3694 * Added silc_gettimeofday to provide generic function
3695 for struct timeval on all platforms. Added the function
3696 to lib/silcutil/silcutil.h.
3698 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3700 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3701 library as they clearly belong there. As a plus side we
3702 can make the actual socket connection routines platform
3705 Added also new generic function silc_socket_read and
3706 silc_socket_write (that used to be silc_packet_[read/write].
3707 The implementation of these are platform specific.
3709 * Added WIN32 specific routines of silc_socket_[read/write]
3710 to lib/silcutil/win32/silcwin32sockconn.c.
3712 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3714 * Added preliminary support for native WIN32 compilation under
3715 cygwin (using the -mno-cygwin option for GCC) to the
3716 ./configure.in.pre. The --with-win32 now prepares the
3717 compilation for native WIN32.
3719 * Rewrote the SILC Scheduler interface in the file
3720 lib/silcutil/silcschedule.h. The scheduler is now context
3721 based and does not have anymore any global static scheduler.
3722 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3723 and created lib/silcutil/win32 directory for WIN32 based
3726 * Added Unix specific network routines to the
3727 lib/silcutil/unix/silcunixnet.c and the old
3728 lib/silcutil/silcnet.c includes now only generic routines.
3730 Added WIN32 specific network routines to the
3731 lib/silcutil/win32/silcwin32net.c.
3733 * Added Unix specific utility functions from the
3734 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3736 * Added WIN32 SILC Scheduler to the file
3737 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3740 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3742 * Do not handle JOIN notify in the server if the target client
3743 is not registered (idata->registered == FALSE). The affected
3744 file is silcd/packet_receive.c.
3746 * Update the nickrec->founder in event_cumode in the Irssi SILC
3747 client. Affected file irssi/src/silc/core/silc-channels.c.
3749 * Fixed the CUMODE_CHANGE notify handling in the server when
3750 server and router are announcing their clients on channels.
3751 Now the mode changes are saved and notified correctly. The
3752 affected file is /silcd/packet_receive.c.
3754 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3755 They really did not replace the cache entry in the ID Cache.
3756 Now they do that. Affected file silcd/idlist.c.
3758 * Fixed the KICK notify handling in the Irssi SILC client to
3759 update the channel records so that the kicked client does not
3760 appear to be on the channel. The affected file is
3761 irssi/src/silc/core/silc-channels.c.
3763 * Always update the conn->current_channel when executing command
3764 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3766 * Fixed the KILL notify handling in Irssi SILC client to remove
3767 the killed client on all channels.
3769 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3771 * Fixed the silc_parse_command_line to remove extra spaces
3772 from the start and end of the arguments. Affected file is
3773 lib/silcutil/silcutil.c.
3775 * Cancel and free any active protocol in the function
3776 silc_server_close_connection. Affected file silcd/server.c.
3778 * Cancel and free any active protocol in the function
3779 silc_client_close_connction. Affected file is
3780 lib/silcclient/client.c.
3782 * Do not execute the KILL command for clients that are in
3783 history (ie. they are not in the network). Affected file is
3786 * Fixed KILL notify handling, client does not crash anymore.
3787 Affected file irssi/src/silc/core/silc-channels.c.
3789 * Reduced the default packet buffer size from 2048 to 1024 in
3790 lib/silccore/silcpacket.c.
3792 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3793 counter to the SKE context that is incresed when the SKE library
3794 performs async operation outside the library. If the outside
3795 process frees the SKE context and FREED status will be set
3796 and the library will detect after the sync operation that the
3797 libary is freed. The affected files are
3798 lib/silcske/silcske[_status].[ch].
3800 * Resolve the client entry information in the function
3801 silc_client_channel_message to assure that NULL pointer is not
3802 passed as client entry to the application. */
3804 * Fixed the task timeout calculation to assure that there is
3805 never negative timeouts. The affected file is
3806 lib/silcutil/silcschedule.c.
3808 * Fixed the channel user mode notification sending in server.
3809 It was sent point-to-point to the router (or to server by router)
3810 but it needs to be destined to a channel. The routines now
3811 supports sending the channel user mode notifys to the channels
3812 when announcing clients and channels. Affected files are
3813 silcd/server.c and silcd/packet_receive.c.
3815 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3816 It did not actually replace the old channel entry in the cache.
3817 Affected file lib/silcclient/client_notify.c.
3819 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3821 * Fixed a possible crash in silc_packet_send_prepare. It now
3822 assures always that there is enough space in the buffer and
3823 at the tail area of the buffer (for MAC).
3825 Fixed the inbound buffer reallocation in silc_packet_read.
3826 It was old code and did not handle the reallocation correctly.
3829 The affected file is lib/silccore/silcpacket.c.
3831 * Fixed buffer overflow in silc_parse_nickname in the file
3832 lib/silcutil/silcutil.c.
3834 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3836 * make install generates new server keys only if there is not
3839 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3841 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3842 Added check that if the NOREPLY is set then we will not send
3843 the away message. This avoids infinite loop of away messages
3844 if both clients are away. The affected file is
3845 lib/silcclient/client_prvmsg.c.
3847 * Fixed client crash if /NICK was given without arguments.
3848 Affected file lib/silcclient/command.c.
3850 * Server does not send the invite list in INVITE command back
3851 to the client if the list was not altered. Added this notion
3852 to the protocol spec as well. Affected file silcd/command.c.
3854 Fixed possible crash in INVITE command by checking the
3855 value of silc_server_get_client_route command.
3857 * Fixed the INVITE notify type handling. The arguments are now
3858 taken in correct order and client does not crash. The affected
3859 file is irssi/src/silc/core/silc-channels.c.
3861 Removed the "Inviting xxx to channel" message from the
3862 client library away and let the application handle it.
3863 Affected file lib/silcclient/command.c. Added that message
3864 to Irssi SILC client's message formats.
3866 * Fixed CMODE command crash in client. It now checks the
3867 amount of arguments correctly and does not crash. The affected
3868 file is lib/silcclient/command.c.
3870 * Do not create new channel automatically in silc_channels_join
3871 but check whether the channel by that name already exists.
3872 Affected file irssi/silc/core/silc-channels.c.
3874 * Do not send the SERVER_SIGNOFF to router if the disconnected
3875 entity was the router. Affected file silcd/server.c.
3877 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3878 SILC client as it was missing from there.
3880 Added the handling of the KICK notify to the Irssi SILC client
3881 as it was missing. Added "you have been kicked" message to
3882 Irssi SILC client's message modules formats.
3884 Added the handing of the KILL notify to the Irssi SILC client
3885 as it was missing. Added the kill message module formats
3888 The affected file is irssi/src/silc/core/silc-channels.c.
3890 * The router did not save the channel mode the server announced.
3891 Affected file silcd/packet_receive.c.
3893 * Fixed a possible crash in INFO command in server. If the
3894 server did not provide the server info it crashed. Affected
3895 file silcd/command.c.
3897 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3899 * Fixed the GETKEY command in the server to check also the
3900 global list. Otherwise the GETKEY would not work correctly
3901 in normal SILC server. Affected file silcd/command.c.
3903 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3905 * Fixed GETKEY crash, it crashed if the command did not succseed.
3907 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3909 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3910 is now real and not just an macro interface to GMP.
3912 Removed the entire GMP from the source tree and imported new
3913 NSS MPI library instead. Reason for removing GMP is that it is
3914 extremely large and compiles extremely slow. The NSS MPI
3915 is only a few files and compiles in less than 10 seconds.
3916 The speed is also about the same as GMP. The MPI is imported
3917 to lib/silcmath/mpi.
3919 If the system has GMP installed we will still use the GMP.
3920 If it is not then the NSS MPI will be compiled.
3922 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3924 * Merged a long nickname (127 characters long) crash bugfix from
3925 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3927 * Merged a freed memory reference bugfix from Irssi CVS tree.
3928 Affected file irssi/src/core/commands.c.
3930 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Added the server's public key sving and verification to the
3933 server when performing the SKE. This was missing and the
3934 remote server's (or router's) public key was accepted without
3935 checking whether we have it previously or trust it at all.
3936 Affected file silcd/protocol.c.
3938 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3940 * Check in the silc_server_timeout_remote if protocol is active
3941 and make sure that the protocol's final callback is called so
3942 that all memory if freed. Affected file silcd/server.c.
3944 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3946 * silc_server_whois_send_reply crashed the server if the nickname
3947 was 127 characters long. Affected file silcd/command.c.
3949 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3951 * Added sanity check to the silc_server_new_client. If the hostname
3952 is provided inside username then check that the provided hostname
3953 really is the same as the resolved one. If the hostname was not
3954 resolved then check it from the public key. Affected file is
3955 silcd/packet_receive.c.
3957 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3958 if the server disconnected us and the connection is not valid
3959 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3961 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3962 the library to the lib/silcutil/silcutil.[ch].
3964 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3966 * Close log file after open. Affected file
3967 lib/silcutil/silclog.c.
3969 * Check whether sock == NULL in silc_client_send_packet and return
3970 if it is. Affected file lib/silcclient/silcclient.c.
3972 * Check rec->entry == NULL in the Irssi SILC Client before
3973 sending the channel message. Affecte file is
3974 irssi/src/silc/core/silc-servers.c.
3976 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3978 * Merged a splitted window bugfix from Irssi CVS tree. The
3979 affected file is irssi/src/fe-text/textbuffer-view.c.
3981 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3982 It did not print nickname.
3984 * Improved the distributions system a bit.
3986 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3988 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3989 irssi/src/fe-text/gui-window.c.
3991 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3992 to in-active server. The affected file is
3993 irssi/src/silc/core/client_ops.c.
3995 * Resolve the client in USERS command reply if the entry does
3996 not have username resolved. The affected file is
3997 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3998 command to WHOIS command to really resolve stuff. The USERS
3999 is not used any more in any critical section so WHOIS can
4000 be used even though it might be slower than IDENTIFY.
4002 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4005 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4007 * Changed the protocol API a bit more consistent in the
4008 lib/silccore/silcprotocol.[ch].
4010 * Changed the following headers to ROBODoc format:
4012 lib/silccore/silcpayload.h
4013 lib/silccore/silcprotocol.h
4014 lib/silccore/silcsockconn.h
4016 All core library headers are now formatted.
4018 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4020 * Fixed a bug in Irssi SILC client; do not show that you are
4021 server/router operator if you really are not. Affected file is
4022 irssi/src/silc/core/client_ops.c.
4024 * Renamed silc_command_free_payload to silc_command_payload_free.
4025 Affected file lib/silccore/silccommand.h
4027 * Added silcmath.h to include the prototoypes of various routines
4028 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4031 * Changed the following headers to ROBODoc format:
4033 lib/silccore/silcchannel.h
4034 lib/silccore/silccommand.h
4035 lib/silccore/silcid.h
4036 lib/silccore/silcidcache.h
4037 lib/silccore/silcmode.h
4038 lib/silccore/silcnotify.h
4039 lib/silccore/silcpacket.h
4040 lib/silcmath/silcmath.h
4042 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4044 * Added checking to the server code not to start the server if
4045 ciphers and stuff are not configured properly. Affected files
4046 silcd/serverconfig.[h] and silcd/server.c.
4048 * Changed the layout of the header files of the public interfaces
4049 in the SILC libraries. The new layout supports ROBODoc
4050 documentation tool (and some others) so that it is easy to create
4051 a library reference manual. All the other headers and source
4052 code must still follow the CodingStyle document. Also source
4053 code must not include these ROBODoc stuffs, only the headers.
4054 Furthermore, all public interface headers must now be named
4055 by using `silc' prefix, example: silcapi.h, silccipher.h.
4056 Some files were renamed due to this. All the other headers
4057 must not be used as public interfaces. I will update the
4058 CodingStyle document later. Changed following headers, so far:
4060 lib/silcclient/silcapi.h
4061 lib/silccore/silcauth.h
4062 lib/silccore/silcprivate.h
4063 lib/silccrypt/silcdh.h
4065 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Removed silc_client_packet_send_flush from the client library
4070 as it is not needed. Affected file lib/silcclient/client.[ch].
4072 * Added printing of message of unresolved authentication method
4073 to the Irssi SILC client. Added it to the module formats.
4074 Removed the same message from the client library.
4076 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4078 * Added new distribution feature, DISTLABEL. Every distribution
4079 can define own preprocessor label that can be used in the
4080 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4081 file distributions, acconfig.h.pre and prepare.
4083 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4085 * Added Makefile.defines_int to include the actual definitions
4086 for Makefile.defines.in. Tested the new distribution system,
4087 created distributions and tested installation.
4089 * Added AWAY message printing to the Irssi SILC client. Added
4090 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4092 * Added SCONNECT command to call the SILC's CONNECT command.
4093 Cannot use CONNECT directly since Irssi uses that internally.
4094 Affected file irssi/src/silc/core/silc-servers.c.
4096 Added ACTION local command. It is same as ME command but takes
4097 the channel as mandatory argument.
4099 Rewrote some of the Irssi's help files to suite for SILC
4102 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Added Makefile.defines[.in] that should for now on be included
4105 in all Makefile.am file in the source tree. That file includes
4106 all common compilation definitions for SILC source tree.
4108 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4110 * Minor changes to the ./prepare script to change the package
4111 name according the distribution name to the configure.in.
4113 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4115 * Created new distribution system. Added file `distributions'
4116 that defines all the distributions that can be created out of
4117 the SILC source tree. The ./prepare script now reads that
4118 file to determine how to prepare the distributions. The
4119 first argument to the ./prepare is the name of the distribution
4120 and second is the version of the distribution. If given
4121 without arguments it creates the default (toolkit) distribution
4122 with the default version (defined in ./prepare).
4124 All Makefile.am files that are subject to the distributions
4125 are now named as Makefile.am.pre. These are ./Makefile.am
4126 and lib/Makefile.am. Others may be changed later.
4128 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4130 * Added invite list, ban list, some key management and connection
4131 error message printing to module formats in the Irssi SILC client.
4133 * Added new silc_client_set_away_message to set the away message
4134 that is back to the person who sent private message. The
4135 affected file lib/silcclient/silcapi.h and the
4136 lib/silcclient/client_prvmsg.c.
4138 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4140 * Fixed the private message sending in the Irssi SILC client,
4141 added local command KEY to the Irssi SILC client.
4143 Added key management and key agreement message formats to the
4144 irssi/src/fe-common/silc/module-formats.[ch].
4146 Added USERS (alias WHO) printing, server/router operator
4147 indication and LIST command printing to the module formats.
4149 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Fixed channel joining notify handling, cumode notify handling
4152 from Irssi SILC client.
4154 * Added SILC specific module-formats to the Irssi SILC client so
4155 that SILC specific message hilighting, colors etc is possible.
4156 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4158 Added channel mode, channel user mode, actions, notices,
4159 whois and whowas printing to the the module-formats.c.
4161 * Fixed a bug in channel deletion in the server. The channel
4162 is not left to the cache even if the channel founder auth mode
4163 is set when there are no users anymore on the channel. Affected
4164 file silcd/server.c.
4166 * The silc_net_localhost now resolves the entire hostname including
4167 the domain name. Affected file lib/silcutil/silcnet.c.
4169 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Changed the ask_passphrase client operation to be ascynchronous.
4172 It has now a completion callback and a context that the
4173 application must call after it has got the passphrase from
4174 the user. Affected files lib/silcclient/silcapi.h,
4175 lib/silcclient/protocol.c, lib/silcclient/command.c and
4178 Added SilcAskPassphrase callback that the application calls
4179 to deliver the passphrase to the library.
4181 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4182 The public key verification and especially a certificate
4183 verification is asynchronous procedure.
4185 Added new SILC_SKE_STATUS_PENDING status to indicate the
4186 request is pending and a callback will be called to finalize
4189 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4190 indicate that remote end did not send its public key (or
4191 certificate), even though we require it. Added check for this
4192 condition in the SKE. This was a security bug, now fixed.
4194 Defined new SilcSKEVerifyCbCompletion callback that is called
4195 when the verification process is completed.
4197 The affected files lib/silcske/silcske_status.h and
4198 lib/silcske/silcske.[ch].
4200 * Changed the verify_public_key client operation to be async
4201 as well. Defined SilcVerifyPublicKey callback that is used to
4202 indicate the success of the public key verification process.
4204 Changed the server and client to use the new async client
4207 * Changed the Irssi SILC client's internal scheduler to be called
4208 twice as many times as it used to be. As a result the client
4209 should be a bit faster now. Affected file is
4210 irssi/src/silc/core/silc-core.c.
4212 * Added support to Irssi SILC client of asynchronous public key
4213 verification and passphrase inquiry. Affected file is
4214 irssi/src/silc/core/silc-core.c.
4216 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4218 * Do not say "You have left channel %s" in client library.
4219 Moved it to the application. Affected files are
4220 lib/silcclient/command.c and silc/client_ops.c.
4222 * Fixed silc_client_get_clients. Command context was not
4223 duplicated and was freed memory in the callback. Affected
4224 file lib/silcclient/idlist.c.
4226 * Do not say "you are now talking..." on JOIN command in the
4227 client library. The appliation must handle it.
4229 * Do not say ".. changed topic to" in command reply in the
4230 client libary. The application must handle it.
4232 * Fixed TOPIC command sending in the client library.
4234 * Fixed a memory leak in silc_client_command_free in the file
4235 lib/silcclient/command.c.
4237 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4239 * Imported a modified version of Irssi client to the source tree.
4240 The Irssi will be used to create a new client called
4241 Irssi SILC. Imported to irssi/.
4243 Added silc_core_init_finish function to the Irssi. Affected
4244 file irssi/configure.in.
4246 A lot changes in the Makefile.ams around the irssi tree.
4248 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4250 * Do not rehash if the new size is same as the old size of the
4251 hash table, in the silc_hash_table_rehash*. The affected file
4252 lib/silcutil/silchashtable.c.
4254 * Replaced hash_table_del_by_context calls from the server
4255 (when channel->user_list and client->channels) to the
4256 hash_table_del as it is sufficient and faster.
4258 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4260 * Added silc_hash_table_list, silc_hash_table_get and the
4261 SilcHashTableList structure to provide an alternative way to
4262 traverse the hash table. The affected files are
4263 lib/silcutil/silchashtable.[ch].
4265 * Changed the server's idlist routines to use the hash table
4266 routines to optimize the code.
4268 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4270 * Replaced the client entry's `channel' list and channel entry's
4271 `user_list' list to hash tables for optimized lookup. Changed
4272 the code to use the hash table interface around the code.
4273 Affected file lib/silcd/idlist.[ch].
4275 * Added `auto_rehash' boolean argument to the function
4276 silc_hash_table_alloc to indicate whether the hash table should
4277 auto-rehash when it thinks is appropriate time. It will
4278 increase the hash table size if the there is twice as much
4279 entries in the table than the size of the table, and will
4280 decrease the size if there are twice as less entries than
4281 the size of the table.
4283 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4285 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4287 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4289 * silc_idcache_purge_by_context deletes the entry now by context
4290 as it is supposed to do. Affected file lib/silccore/idcache.c.
4292 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4293 client is not anymore valid (WHOWAS givens the info) and not
4294 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4296 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4298 * Removed the `data' and `data_len' arguments from the ID Cache
4299 interfaces and added `name' argument. ID Cache does not handle
4300 anymore the binary data only a names associated with given ID.
4302 * When hashing a Client ID with silc_hash_id the entire ID is
4303 not hashed anymore, instead only the hash of the Client ID is
4304 hashed. This way we can access the Client ID from the cache
4305 with Client ID but with the hash of the ID (which is a hash of
4306 the nickname) as well without any difference in performance.
4308 Added also silc_idcache_find_by_id_one_ext to do one on one
4309 searching when we have the actual ID. Added also function
4310 silc_hash_client_id_compare. The affected files are
4311 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4313 * When hashing the name associated with a ID it is always done
4314 in lowercase. This way we can access the cache without worrying
4315 about case-sensitivity, even though, for example nicknames are
4318 * Fixed a bug in server with channel message sending. It put
4319 wrong ID type as destination ID. The affected file
4320 silcd/packet_send.c.
4322 * silc_idcache_del_by_context now deletes from all hash tables
4323 by context. Affected file lib/silccore/idcache.c.
4325 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4327 * Changed the client library to use the new ID Cache interface.
4328 Changes around the source tree.
4330 * Added silc_hash_table_rehash_ext to rehash with specific
4331 hash function. Affected file lib/silcutil/silchashtable.[ch].
4333 * Added silc_hash_string_compare to compare two strings in the
4334 hash table. Affected file lib/silcutil/silcutil.[ch].
4336 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4338 * Added new function silc_idcache_del_by_context into the
4339 lib/silccore/idcache.[ch].
4341 * Changed the server's ID list routines to use the new ID Cache
4342 interface. Changes around the source tree.
4344 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4346 * Added silc_hash_table_del[_by_context]_ext functions in to the
4347 lib/silcutil/silchashtable.[ch].
4349 Removed silc_hash_table_find_all* routines and added new
4350 silc_hash_table_find_foreach to replace them.
4352 Added silc_hash_table_replace_ext function as extended
4353 replacing function. Separated the simple hash table interface
4354 from the extended hash table interface in the file
4355 lib/silcutil/silchashtable.h.
4357 * Fixed minor bugs and changed it to use some of the new
4358 hash table functions in lib/silccore/idcache.c
4360 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4362 * Added new function silc_hash_table_find_all to return all keys
4363 in the hash table by the specified key. As the hash table is
4364 collision resistant it also makes it possible to have several
4365 duplicate keys in the hash table. This function may be used to
4366 find all of the keys from the hash.
4368 Added user_context arguments to the SilcHashFunction,
4369 SilcHashCompare and SilcHashDestructor to deliver user specified
4372 Added new fuctions silc_hash_table_find[_all]_ext to do
4373 extended lookup with specified hash and compare functions and
4374 specified user contexts.
4376 Added new function silc_hash_table_add_ext to add the key
4377 with specified hash function and user context.
4379 Added new function silc_hash_table_foreach to traverse all
4380 entrys in the hash table. Added SilcHashForeach callback
4383 Added new function silc_hash_table_del_by_context to delete
4384 the entry only if the context associated with the key matches.
4386 Affected files are lib/silcutil/silchashtable.[ch].
4388 * Removed silc_hash_[server/client/channel]_id and added just
4389 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4390 silc_hash_id_compare to compare two ID's using as the hash table
4391 comparison function. Added also silc_hash_data to hash
4392 binary data and silc_hash_data_compare to compare it.
4394 * Removed silc_idlist_find_client_by_hash as it is not needed
4395 anymore. Affected file silcd/idlist.[ch].
4397 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4398 to use internally the SilcHashTable. The new ID Cache is a lot
4399 faster than the old one. Some of the ID Cache interface was also
4400 rewritten and obsolete and stupid functions were removed.
4402 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4404 * Added entry_count field to the SilcHashTable to keep the number
4405 of the entries in the table. Implemented the function
4406 silc_hash_table_rehash. Added new function
4407 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4409 Fixed a minor bug in silc_hash_table_free.
4411 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4412 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4413 into the lib/silcutil/silcutil.[ch].
4415 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4417 * Implemented a collision resistant hash table into the
4418 lib/silcutil/silchashtable[ch]. See the header and the source
4419 for the SilcHashTable API.
4421 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4423 * Merged dotconf version 1.0.2 into lib/dotconf.
4425 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Do not compile anything in lib/silcsim/* if the SIM support
4428 is not enabled. The tree should now compile without problems
4431 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4433 * Compiled the SILC under cygwin. Compiled and tested briefly
4434 without problems. More tests needed. The SIMs didn't compile
4437 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4439 * Fixed possible crash in silc_get_username in the
4440 lib/silcutil/silcutil.c.
4442 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Fixed a va_arg in silc/client_ops.c.
4446 * Oops, RC5 routines were named AES and caused some problems
4447 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4449 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4451 * Added new SilcIDIP structure into the lib/silccore/id.h and
4452 replaced the old `ip' fields from all SILC ID's to that type.
4453 This is a step towards IPv6 support.
4455 The silc_id_get_len takes now the ID as an extra argument.
4456 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4457 both IPv4 and IPv6 based ID's.
4459 The affected files are lib/silccore/id.[ch] and other files
4460 around the tree using these routines.
4462 * Removed the ID length arguments in server from various
4463 silc_server_send_notify_* routines -> they are not needed
4466 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4468 * Fixed memory leak in silc_encode_pem_file in the file
4469 lib/silcutil/silcutil.c.
4471 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Check minor version as well in the SKE. Affected files are
4474 silcd/protocol.c and lib/silcclient/protocol.c.
4476 * Added --identifier option to the server so that an identifier
4477 can be when creating the public key for the server. Affected
4478 file is silcd/silcd.c.
4480 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4481 lib/silccrypt/silcpkcs.c.
4483 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4485 * Register default ciphers and stuff when using -C option with
4486 the server. Affected file sildc/silcd.c.
4488 * Put back the servers public key filename format, it is better
4489 than the new one. For now, the client keys are saved with the
4490 new filename format. The affected file silc/client_ops.c.
4492 * Implemented the Cipher API for the rest of the ciphers that
4493 did not implement it or implemented it the wrong way.
4495 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4497 * Register default ciphers and stuff when using the -S option
4498 in the client. Affected file silc/silc.c. Same also when
4499 creating new key pair with -C option.
4501 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4503 * Fixed the silc_verify_public_key client operation function to
4504 save the public keys differently. The fingerprint is now
4505 used as filename and not the hostname. This way also the
4506 client keys are saved uniquely and not with hostnames. The
4507 affected file is silc/client_ops.c.
4509 * Trimmed the silc_hash_fingerprint function to remove extra
4510 whitespaces from the end of the fingerprint. The affected
4511 file is lib/silccrypt/silchash.c.
4515 * Added silc_cipher_register_default function to register all
4516 default ciphers. It can be used when configuration files
4517 does not exist and the application does not want any specific
4518 ciphers in any specific order.
4520 The SilcDList is now used as silc_cipher_list dynamically
4521 allocated cipher list. Removed the static list all together
4522 and now all ciphers must be allocated to the dynamic list.
4523 The silc_cipher_alloc routine was changed to check only the
4526 All silc_cipher_* routines that used to return int returns
4529 The affected files lib/silccrypt/silccrypt.[ch].
4531 * The same thing was done to silc_hash_* as for silc_cipher_*
4532 routines. Affected files lib/silccrypt/silchash.[ch].
4534 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4535 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4536 Added also silc_pkcs_[un]register[_default] functions.
4537 Removed the data_context from the PKCS API.
4539 * Added silc_hmac_register_default function to register default
4540 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4541 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4542 to unregister all hmacs at once.
4544 * Register the default ciphers, hash functions, PKCSs and HMACs
4545 if client's configuration file does not exist. The affected
4548 * The client did not load the hash functions from the SIM
4549 modules at all. Added support for this. Affected file is
4550 silc/clientconfig.c.
4552 * When decoding public key with silc_pkcs_public_key_decode, check
4553 the supported algorithm only if PKCS are registered. Affected
4554 file lib/silccrypt/silcpkcs.c. The same was done with the
4555 silc_pkcs_private_key_decode.
4557 * Fixed the SILC List routines to keep the list always in order.
4558 It used to change the list's order when traversing the list but
4559 not it preserves the order. Affected file lib/trq/silclist.h.
4561 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Added the client library to use the SilcSocketConnection's
4564 reference counter (by silc_socket_dup) to prevent the bug that
4565 the socket object may be freed underneath async operation.
4567 * The name resolv library checking fixes in the configure.in.pre.
4570 * Created new version of the protocol drafts for future
4571 development. The -03 drafts are the ones that will be changed
4572 in the trunk now and the -02 will remain as they are.
4574 * Send list of CUMODE notifys to the router when announcing
4575 the channel users to the router. Affected file silcd/server.c.
4576 If the router receiving channel founder CUMODE for a channel
4577 that already has channel founder it will send CUMODE notify
4578 to the sender to remove the channel founder rights from the
4579 announced client. Affected file silcd/packet_receive.c.
4581 * The CUMODE notify may now use Server ID as well as the entity
4582 who changes the mode. Updated protocool specs.
4584 * Updated INSTALL and README files.
4586 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4588 * New web pages in the http://silc.pspt.fi. The pages was
4593 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4595 * Implemented the [DenyConnectin] config section in the server.
4596 Added silc_server_config_denied_conn to check whether incoming
4597 connection is denied. Affected file silcd/serverconfig.[ch].
4599 * Do not check the ports when checking the incoming configuration
4600 data if the port is 0, meaning any. Affected file is
4601 silcd/serverconfig.c.
4603 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4605 * Fixed buffer overflow in silc_string_compare in the file
4606 lib/silcutil/silcutil.c.
4608 * Fixed double free in silc_server_command_leave in the file
4611 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4613 * Fixed the version checking in the server. Affected file is
4616 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Fixed the configuration data fetching when accepting new
4619 connections in the server. Affected file silcd/server.c.
4621 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Added `sender_entry' argument to the function
4624 silc_server_packet_relay_to_channel so that we can check
4625 whether some destination actually belongs to the same route
4626 the sender belongs (ie, we must not resend the packet to the
4627 sender). Affected file silcd/packet_send.[ch].
4629 * Added `servername' field to the SilcClientEntry in the server
4630 to hold the name of the server where client is from. Affected
4631 file is silcd/idlist.h.
4633 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4635 * Moved the channel message encrypting in the router betwen
4636 router connections from silc_server_channel_message to the
4637 silc_server_packet_relay_to_channel since we want to check
4638 whether we have anybody channel before encrypting anything.
4639 Affected files silcd/packet_[receive/send].c.
4641 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Fixed the [AdminConnection] server config section to support
4644 multiple entries. Affected file silcd/serverconfig.c.
4646 * Added support into the server to check the validity of the
4647 incoming connection before executing any KE or authentication
4650 * The connection configuration is now saved to the KE and
4651 connection auth protocol contexts and not fetched anymore in
4652 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4654 * The local hosts listenning address and port is also resolved
4655 now when starting the server. We want to have the socket object
4656 to include the real address and port for the listener. Added
4657 new function silc_net_check_local_by_sock into the files
4658 lib/silcutil/silcnet.[ch].
4660 * Fixed a broadcast bug in server -> do not broadcast if we
4663 * Fixed a routing bug. Do not route broadcast packets ever.
4664 Broadcast packets must be processed always and not routed since
4665 they may be destined to some other host than yourself and thus
4666 would get routed without no good reason. Affected file is
4669 * Added function silc_server_config_is_primary_route to check
4670 whether primary router connection has been configured (a router
4671 configuration that we are initiating). If there is not, we
4672 will assume that there is only two routers in the SILC network
4673 and we will use the incoming router connection as our primary
4674 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4676 * Changed the order of the broadcasting. Broadcast _after_ the
4677 packet has been processed not before. Affected file is
4680 * Fixed a [ClientConnection] parsing bug. The port was never
4681 parsed correctly thus resulting to port 0. Affected file
4682 silcd/serverconfig.c.
4684 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4685 argument and did not set the broadcast packet flag. Affected
4686 file silcd/packet_send.c. Fixed same bug in the function
4687 silc_server_send_notify as well.
4689 * If we receive NEW_ID packet for our own ID in the server, ignore
4692 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4696 * Removed the nickname from the Private Message Payload.
4697 Updated the code and the protocol specs.
4699 * Updated protocol specs for submitting to the IETF.
4701 * Tweaked the Random Number Generator a bit. Affected file
4702 lib/silccrypt/silcrng.c. Exported a new function
4703 silc_rng_[global]_add_noise which can be used to add more
4706 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4708 * Do not parse packets with different timeout when protocol
4709 is active -> may cause problem with rekey. Affected file
4712 * When server receives signoff notify it must not create
4713 new channel key if the client is on any channels since the
4714 sender of the signoff notify will create it.
4716 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4718 * Added printing of error messages during SKE protocol from the
4719 failure packet sent by server during SKE. Affected file
4722 * Removed the client's failure_callback handling with timeout
4723 and handle it immediately when received.
4725 * The SKE library returned wrong type in SUCCESS and FAILURE
4726 packets. They must be 32 bit MSB not 16 bit MSB.
4728 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4730 * Ok, rewrote the logic of the re-key and now it seems to work.
4731 I tested it on high traffic with frequent re-keys without
4732 problems. Added hmac_receive (and renamed hmac to hmac_send)
4733 in SilcClientConnection in lib/silcclient/client.h and
4734 in SilcIDListData in silcd/idlist.h. Also, removed the
4735 SilcPacketParserContext's cipher and hmac fields as they are
4736 not needed anymore and actually caused some problems when
4737 the ciphers and hmac's changed underneath the packet parser.
4739 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * If re-key protocol is active then process the incoming packets
4742 synchronously since we must assure that icoming packets encrypted
4743 with the old key is processed before the new keys is set to
4744 use. This is true other packets than for REKEY packets.
4745 Affected file silcd/server.c. The same was done to client library
4746 as well, affected file lib/silcclient/client.c.
4748 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * Fixed bug in client and server to accept the force send if
4751 the packet is send from silc_[server/client]_packet_process
4752 function. Otherwise the packets are never delivered, oops.
4754 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Disable force sending of packets when REKEY protocol is active.
4757 We must assure that no packet is sent directly when rekey is
4758 performed. All packets must be sent through packet queue.
4759 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4760 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4761 function is silc_[server/client]_packet_send_real to check
4764 * Replaced the SIM paths from example config files to
4765 /usr/local/modules. Also, make install creates now
4766 /usr/local/silc/logs directory to hold all the SILC server
4769 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4771 * Made the configure.in.pre work on Solaris. Patch by salo.

4780 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * When MAC computation fails the silc_packet_decrypt returned 0
4783 even though it was supposed to return -1. Fixed this. The
4784 affected file is lib/silccore/silcpacket.c.
4786 * Do not replace the config files in /etc/silc (in make install)
4787 if they already exist. Affected file ./Makefile.am.
4789 * Do not send re-key packets immediately but through packet queue.
4790 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4792 * Changed silc_net_check_host_by_sock to return FALSE if the
4793 IP/DNS could not be resolved. Though, it returns the IP address
4794 now even if it could not resolve it (but returns also FALSE).
4795 Affected file lib/silcutil/silcnet.[ch].
4797 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Added silc_pkcs_decode_identifier to decode the public key's
4800 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4801 Added also silc_pkcs_free_identifier. Added also new context
4802 SilcPublicKeyIdentifier.
4804 * Added -S option to the silc client. It is used to dump the
4805 contents of the specified public key file.
4807 * Changed the PKCS api to return the public key length when
4808 setting the public key.
4810 * Fixed a fatal bug in the public and private key file loading.
4811 Affected file lib/silccrypt/silcpkcs.c.
4813 * Execute the packet parsing for client with zero (0) timeout
4814 if the protocol is active. Affected file silcd/server.c.
4816 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4818 * Made the key generation options to the silcd program. Added
4819 -C option, equivalent to client's option.
4821 * Added new [ServerKeys] config section to the server. It
4822 configures the server's public and private key.
4824 * Defined generic Public Key Payload into the protocol
4825 specification to send specific type of public keys and
4828 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4829 public key or certificate.
4831 * Implemented the GETKEY command to the server and to the
4832 client library and on user interface.
4834 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4836 * Made preliminary `make install' work.
4838 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4840 * Added SilcServerRekey context into silcd/idlist.h.
4842 * Added the PFS support as defined in the specification to the
4843 SKE protocol. Affected files lib/silcske/*.c.
4845 * Added `ske_group' field to the SilcServerRekey context to hold
4846 the number of the SKE group that is used with PFS in re-key.
4847 Affected file silcd/idlist.h.
4849 * Added PFS re-key support to the server. Affected file is
4852 * Added silc_protocol_cancel to cancel execution of the next
4853 state of the protocol. Affected file is
4854 lib/silccore/silcprotocol.[ch].
4856 * Added the re-key support with and without PFS to the client
4857 library. Re-key is performed once in an hour, by default.
4859 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4860 Added silc_client_rekey_callback and silc_client_rekey_final.
4861 Affected files are lib/silcclient/protocol.[ch] and
4862 lib/silcclient/client.[ch].
4864 * Removed the `hmac_key' and `hmac_key_len' fields from the
4865 SilcClientConnection structure; not needed. Affected file is
4866 lib/silcclient/client.h.
4870 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4872 * Do not ask whether user wants to use the negotiated private key
4873 for private messages, just use it. Affected file is
4874 silc/local_command.c.
4876 * Added `send_enc_key' and `enc_key_len' fields to the
4877 SilcIDListData structure since they are needed in the re-key
4878 phase. Affected file is silcd/idlist.[ch].
4880 * Implemented the simple re-key protocol into the server.
4881 Affected files silcd/server.c and silcd/protocol.[ch]. The
4882 re-key will be performed once in an hour, by default.
4884 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4885 Added silc_server_rekey, silc_server_rekey_callback and
4886 silc_server_rekey_final.
4888 * Removed Tunneled flag from the protocol. Updated the code
4889 and the specifications.
4891 * Adde `pfs' field to the SilcIDListData to indicate whether
4892 the PFS is to be performed in the re-key. Affected file is
4895 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4898 int64 of at least the xintXX size. If void * is less that 4
4899 bytes uint32 * will be used. Defined bool as boolean.
4901 * Changed _ALL_ unsigned long and unsigned int to uint32,
4902 unsgined short to uint16 in the source tree.
4904 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4905 not handle clients that has entry->data.registered == FALSE.
4906 They are not in the network anymore. Affected file is
4909 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4911 * Implemented the sending of the SERVER_SIGNOFF notify in the
4912 server. Affected file is silcd/server.c.
4914 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4915 Added also silc_notify_payload_encode_args into the
4916 lib/silccore/silcnotify.[ch].
4918 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4919 Affected file silcd/packet_receive.c.
4921 * Implemented the SERVER_SIGNOFF notify handling in the client
4922 library. Affected file lib/silcclient/client_notify.c. Also,
4923 implemnted the printing of the SERVER_SIGNOFF info to the
4924 application. Affected file silc/client_ops.c.
4926 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4927 if the deleting was successful. Affected file silcd/idlist.[ch].
4929 * Added support for public key authentication in the connection
4930 authentication protocol in the client library. Affected file
4931 lib/silcclient/protocol.c.
4933 * Changed the server's silc_idlist_get_clients_by_* interface
4934 to support already allocated array so that new entries may be
4935 added to pre-allocated array. Affected file silcd/idlist.[ch].
4936 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4937 and command replies.
4939 * All command reply functions in the server now calls the
4940 pending command callback even if error occured. This way the
4941 error will be delivered to the client as well. Affected files
4942 silcd/command.c and silcd/command_reply.c.
4944 * Fixed INFO command to return local server's info if no server
4945 was provided. Affected file lib/silcclient/command.c.
4947 * Removed RESTART command for good. Updated the code and the
4950 * Rewrote parts of the task system. It is a bit simpler now.
4951 Removed unsued task priorities. The affected files are
4952 lib/silcutil/silctask.[ch].
4954 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4956 * Moved the USERS printing from the library to the application.
4957 Affected files lib/silcclient/command.c and silc/client_ops.c.
4959 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4963 * Added channel key re-key support. The re-key is perfomed
4964 only by the router and is done once in an hour. Added `rekey'
4965 field to the SilcChannelEntry in the server. Affected files
4966 silcd/server.c and silcd/idlist.h.
4968 * Added silc_task_unregister_by_context into the file
4969 lib/silcutil/silctask.[ch].
4971 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4973 * Added SILC_UMODE_GONE mode to indicate when the client is not
4974 present in the SILC network. Added also support to the local
4975 command AWAY that will set this mode. Added support of showing
4976 "xxx is gone" in WHOIS command. The USERS command shows the
4977 gone status as well.
4979 * Fixed setting server and router operator privileges in the
4980 server's UMODE command. Affected file silcd/command.c.
4982 * Merged the SKE KE1 and KE2 payloads into one payload. The
4983 new KE payload is equivalent to the old KE2 payload.
4985 Cleaned up the SKE Start Payload parsing. It now uses the
4986 simple buffer unformatting to do the parsing. A lot faster
4989 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4990 to the SKE that is used to indicate whether both of the SKE
4991 parties should perform authentication. By default only the
4992 responder performs authentication. By setting this flag also
4993 the initiator must do authentication. By default it is unset
4994 since in normal SKE case, client to server connection, only
4995 the responder should do authentication. When doing SKE between
4996 two clients both should perform authentication. Updated the
4997 code and the protocol specs.
4999 * A little fix to IDENTIFY command in the server. Search the
5000 client first by hash not nickname. Affected file is
5003 * Fixed the silc_client_close_connection to support closing
5004 the client to client connections wihtout deleting too much
5005 data. Affected file lib/silcclient/client.c.
5007 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5008 are received if protocol used to be active but is not anymore
5009 the application would crash due to NULL pointer dereference.
5010 Affected files silcd/server.c and lib/silcclient/client.c.
5012 * Added `hash' field to the SilcClientConnection to include
5013 the hash function negotiated in the SKE protocol.
5015 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5016 to set the channel founder authentication data. A client can
5017 claim the founder rights later by providing the authentication
5018 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5019 This way the channel founder can regain the channel founder
5020 privileges even it is left the channel. This works only on
5021 local server and the client must be connected to the same
5022 server to be able to regain the founder rights. Updated the
5023 protocol specs accordingly.
5025 Added support to the CMODE command in the client to set the
5026 founder auth data. Read the README to see how to set it.
5028 Added support to the CUMODE command to claim the founder
5029 rights. Read the README to see how to do it.
5031 Added support for the founder authentication to the Channel
5032 Entry in the server. Affected file silcd/idlist.h.
5034 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5035 server's CMODE command. Affected file silcd/command.c.
5037 * Added the following new functions into lib/silccore/silcauth.[ch]:
5038 silc_auth_get_method and silc_auth_get_data.
5040 * The server now saves the remote hosts public key to the
5041 SilcIDListData pointer. Affected file silcd/protocol.c.
5043 * The normal server now does not remove the channel entry from
5044 the cache if the founder authentication data is set. It used
5045 to remove it if the founder was the last one on the channel on
5046 the server and left the channel. The auth data is saved and
5047 if the channel is re-joined later the old entry is used with
5048 the old auth data. Affected files silcd/command_reply.c and
5051 * Removed the `pkcs' field from the SilcIDListData structure
5052 in the server; it is not used. Affected file silcd/idlist.h.
5054 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Fixed packet processing on slow links. Partial packets were
5057 never re-processed because the incoming data buffer was cleared
5058 by the application. Application must not directly clear the
5059 sock->inbuf, the packet processing routines handle it. Fixed
5060 this in client library and in server.
5062 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Fixed the WHOIS and IDENTIFY send reply function to really
5065 check whether to send list or just one entry. Affected file
5068 * Cleaned up the LEAVE command's channel key distribution. The
5069 affected file silcd/command.c.
5071 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5072 can enforce the channel mode as well. In that case the ID
5073 includes the ID of the server. The code now enforces the
5074 mode change if the router have different mode than the server.
5076 * The notify client operation with CMODE_CHANGE notify can now
5077 return NULL client_entry pointer if the CMODE was not changed
5078 by client. Application must check for this.
5080 * Added <Server ID> argument to INFO command to support server
5081 info fetching by Server ID.
5083 * Added silc_server_announce_get_channel_users to get assembled
5084 packets of channel users of the specified channel. Affected
5085 file silcd/server.[ch].
5087 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5088 was freed underneath the ID Cache.
5090 * Re-announce clients when the server received CHANNEL_CHANGE
5091 notify from the router. Affected file silcd/packet_send.c.
5093 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5096 crashed since it did not handle the fact that there is no cipher
5097 called "3" and didn't check the error condition. Now fixed.
5099 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5100 flag. It can be used to send message requests.
5102 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Implemented the RESTART command in the client.
5106 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5107 notice type messages. Added notice printing to the user
5110 * The channel keys are not re-generated if the channel's mode
5111 is PRIVKEY, ie private key on the channel exists. Affected
5112 files silcd/server.c and silcd/command.c.
5114 * Fixed a little bug in channel message delivery when channel
5115 private keys are set in the server. Affected file is
5116 silcd/packet_send.c.
5118 * Changed the setting on channel->on_channel = TRUE from the
5119 silc_client_save_channel_key to the JOIN command reply. The
5120 key payload is not received if the private channel key is set.
5121 Affected file lib/silcclient/command_reply.c and the
5122 lib/silcclient/client_channel.c.
5124 * When the CMODE_CHANGE notify is sent and the channel private
5125 key mode is removed the channel key must be re-generated in
5126 other cells as well. Added this support for the router in the
5127 silcd/packet_receive.c.
5129 * Added new local command NOTICE to send notice message on
5130 channel. Affected file silc/local_command.[ch].
5132 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5134 * Added new local command ME to the client. It is used to send
5135 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5136 some action. Affected file silc/local_command.[ch].
5138 * Changed channel_message and private_message client operations
5139 to deliver the message flags to the application. Added also
5140 the `flags' arguments to the silc_client_send_channel_message
5141 and silc_client_send_private_message functions. Affected file
5144 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5146 * Redefined the Private Message Payload to support private message
5147 keys and to support the new private message flags. Updated
5148 the protocol specs. Flags makes it possible to have for example
5149 CTCP style messages.
5151 * Added new type SilcPrivateMessagePayload and defined an API
5152 for it in the lib/silcclient/silcprivate.[ch].
5154 * Tested private message private keys successfully. Tested the
5155 private message key set, unset and list commands with the new
5158 * Redefined the Channel Message Payload to include the channel
5159 message flags (equal with private message flags) to support
5160 for example CTCP style messages.
5162 * Defined some of the message (for channel and private message)
5163 flags. Updated the protocol specs and added the flags to the
5164 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5166 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5168 * Added SilcKeyAgreementStatus type to the key agreement routines
5169 to indicate the current status and error if one occured.
5170 The status types are defined in the lib/silcclient/silcapi.h.
5172 * Added new local command KEY that is used to set and unset private
5173 keys for channels, set and unset private keys for private messages
5174 with remote clients and to send key agreement requests and
5175 negotiate the key agreement protocol with remote client. The
5176 key agreement is supported only to negotiate private message keys,
5177 it currently cannot be used to negotiate private keys for channels,
5178 as it is not convenient for that purpose.
5180 * Fixed a minor pending callback setting bug in the function
5181 silc_client_get_client_by_id_resolve, now the function works.
5182 Affected file lib/silcclient/idlist.c.
5184 * Added function silc_net_get_local_port to get local bound
5185 port by socket. Added to lib/silcutil/silcnet.[ch].
5187 * Added `sockets' and `sockets_count' fields to the SilcClient
5188 object. They hold the sockets of the listenning sockets in
5189 the client. Listenning sockets may be for example the key
5190 agreement server. Affected file lib/silcclient/client.[ch].
5191 Added functions the silc_client_add_socket and the
5192 silc_client_del_socket. They are exported to the application
5195 * Added ~./silc/clientkeys to support other client's public keys.
5197 * Renamed verify_server_key client operation to verify_public_key
5198 and added one argument to indicate the type of the connection
5199 (server, client etc.).
5201 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5203 * Added silc_server_connection_auth_request to handle the
5204 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5205 silcd/packet_receive.[ch].
5207 * Added silc_server_send_connection_auth_request into the
5208 silcd/packet_send.c to send the connection auth request packet.
5210 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5213 * Fixed the public key authentication in responder side in the
5214 server. The `auth_data' pointer includes the SilcPublicKey
5215 not the path to the public key. Affected file silcd/protocol.c.
5217 * Implemented the public key authentication in the initiator side
5218 in the server. Affected file silcd/protocol.c.
5220 * Removed the [RedirectClient] config section from the server
5221 configuration. Is not needed and I don't want to implement it.
5223 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5225 * Cleaned up the CMODE command in the server. It now works
5226 correctly and supports all the modes defined in the protocol.
5227 Affected file is silcd/command.c.
5229 * Added `hmac_name' field to the SilcChannelEntry in the server
5230 to hold the default HMAC of the channel. It can be set when
5231 creating the channel (with JOIN command). Affected files
5234 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5235 type to indicate the change of the current cipher and hmac
5236 on the channel. Client can safely ignore the <cipher> argument
5237 (if it chooses to do so) since the CHANNEL_KEY packet will
5238 force the channel key change anyway. The <hmac> argument is
5239 important since the client is responsible of setting the new
5240 HMAC and the hmac key into use.
5242 * Fixed the CMODE command in the client library as well.
5244 * Tested CMODE command in router environment successfully.
5246 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5248 * Show the version of the remote client (or server) when connecting
5249 to the server. It is logged to the log file. Affected file
5250 is silcd/protocol.c.
5252 * Fixed the KILLED notify handling in the client library. The
5253 client must be removed from all channels when receiving the
5256 Also, do not remove the client entry when giving the KILL
5257 command but when the KILLED notify is received.
5259 * Removed silc_idlist_find_client_by_nickname from the server.
5260 Not needed anymore. Affected files silcd/idlist.[ch].
5262 * Implemented the CHANNEL_CHANGE notify type handling to the
5263 server. Affected file silcd/server.c.
5267 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5269 * Added silc_server_send_notify_invite to send the INVITE
5270 notify between routers.
5272 * Implemented the INVITE command correctly to the server.
5274 * Implemented the INVITE notify type handling in the server.
5276 * Implemented the INVITE command to the client library and on the
5279 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5281 * Added function silc_server_get_client_resolve to find the
5282 client entry by ID from all ID lists and then resolve it
5283 (using WHOIS) if it cannot be found. Affected file is
5286 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5288 * Implemented the BAN command to the client library.
5290 * The JOIN command in the server now checks the invite list
5293 * Changed the silc_command_reply_payload_encode_va and the
5294 silc_command_payload_encode_va to support that if argument is
5295 NULL it ignores and checks the next argument. Affected file
5296 lib/silccore/silccommand.c.
5298 * Added silc_server_send_notify_ban to send the BAN notify
5299 type between routers.
5301 * Chaned the silc_notify_payload_encode to support that if
5302 argument is NULL it ignores and checks the next argument.
5303 Affected file lib/silccore/silcnotify.c.
5305 * Tested ban lists in router environment successfully.
5307 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5309 * Implemented BAN command to the server, in silcd/command.[ch].
5311 * Removed the BAN and INVITE_LIST modes from the CMODE command
5314 * Added function silc_string_match to regex match two strings.
5315 Affected files lib/silcutil/silcutil.[ch].
5317 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5319 * Redefined parts of the SilcChannelEntry in the server to support
5320 the new ban and invite lists.
5322 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5324 * Redefined the INVITE command. The same command can be used to
5325 invite individuals to the channel but also to manage the invite
5326 list of the channel (to add to and remove from the invite list).
5327 Updated the protocol specs.
5329 * Added new command SILC_COMMAND_BAN that can be used to manage
5330 the ban list of the channel. Updated the protocol specs.
5332 * Removed the channel modes: the SILC_CMODE_BAN and the
5333 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5334 in the CMODE command. The equivalent features are now available
5335 using INVITE and BAN commands. Updated the protocol specs.
5337 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5338 in the network about change in the current ban list. The notify
5339 type is not used by the client.
5341 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5342 support the invite lists.
5344 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5346 * Added new function silc_string_regexify that converts string
5347 including wildcard characters into regex string that can
5348 be used by the GNU regex library. Added into the file
5349 lib/silcutil/silcutil.[ch].
5351 Added silc_string_regex_combine to combine to regex strings
5352 into one so that they can be used as one regex string by
5353 the GNU regex library. Added into the file
5354 lib/silcutil/silcutil.[ch].
5356 Added silc_string_regex_match to match two strings. It returns
5357 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5359 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5361 * Imported GNU regex to the soruce tree into lib/contrib.
5362 Fixed some compiler warning from the regex.c.
5364 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5366 * Fixed MOTD command in the server to work in router environment.
5368 * Fixed the MOTD command in the client library to support
5369 the server argument in the command.
5371 * Added `nickname_len' argument to the silc_idlist_add_client
5372 in the server, as the `nickname' argument may be binary data
5375 * Added silc_idlist_get_channels to return all channels from
5378 * Implemented LIST command to the server. Affected file is
5381 * Implemented the LIST command to the client library and on the
5384 * Added [<user count>] argument to the LIST command reply.
5385 With private channels the user count is not shown.
5387 * Updated TODO and README.
5389 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5391 * The client entry's data.registered must be TRUE even with
5392 global client entry on global client list. The data.registered
5393 is used to check whether the client is anymore in the network,
5394 for example with WHOWAS command so it must be valid.
5396 * Fixed the WHOWAS command in the server. It now actually works
5397 in router environment. Added function into silcd/command_reply.c
5398 silc_server_command_reply_whowas_save.
5400 * Added silc_idlist_purge function to the silcd/idlist.c
5401 to periodically purge the ID Cache.
5403 * Fixed INFO command in the server. It works now in router
5404 environment. Added <server name> argument to the INFO command
5405 reply. Updated the protocol specs.
5407 * Fixed minor bug in silc_idcache_purge to not purge if the
5408 expire value is zero.
5410 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5411 they were buggy because of the WHOWAS information.
5413 * Fixed local command MSG to handle the async resolving of
5414 the remote client properly. It used to fail the first MSG.
5415 Affected file silc/local_command.c.
5417 * Added `data_len' field to SilcIDCache context.
5419 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5421 * Update TODO. Todo in commands in the server.
5423 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5425 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5426 used by routers as broadcast packet to inform other routers
5427 about the changed user mode.
5429 Implemented the notify handling in the server. Affected file is
5430 silcd/packet_receive.c. Added the function
5431 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5433 * Added new generic Channel Payload and deprecated the New Channel
5434 Payload. The New Channel Payload is now the generic Channel
5437 * Added new argument `mode' to the silc_server_send_new_channel
5438 as it is required in the Channel Payload now.
5440 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5441 and created a new and real SilChannelPayload to represent the
5442 new generic Channel Payload. Implemented the encode/decode
5443 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5445 * Added silc_server_get_client_channel_list to return the list
5446 of channels the client has joined for WHOIS command reply.
5447 Affected file silcd/server.[ch].
5449 * Implemented the channel list sending in the WHOIS command reply
5450 in server and in the client.
5452 Implemented the channel list displaying on the user interface
5453 as well. Affected file silc/client_ops.c.
5455 * Added silc_channel_payload_parse_list to parse list of Channel
5456 Payloads. It returns SilcDList list of SilcChannelPayloads.
5457 Client for example can use this function to parse the list of
5458 channels it receives in the WHOIS command reply. The caller
5459 must free the list by calling silc_channel_payload_list_free.
5460 Affected files lib/silccore/silcchannel.[ch].
5462 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5464 * Added one new argument <user mode> to the WHOIS command reply
5465 to return the mode of the user in SILC. Updated the protocol
5468 Implemented it to the server and client.
5470 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5472 * Fixed the mode printing on the user interface on joining.
5473 Affected file silc/client_ops.c.
5475 * Implemented the UMODE command and user modes in general to the
5476 client library and to the user interface.
5478 * Implemented the UMODE command to the server.
5480 * The server now sends UNKNOWN_COMMAND error status if client sends
5481 unknown command. Affected file silcd/command.c.
5483 * All server commands now handle the command identifier the right
5484 way when sending the command reply to the client. The client can
5485 use to identify the command replies with the identifier.
5487 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5489 * Added silc_server_get_client_route to resolve the route to
5490 the client indicated by the client ID. Affected file is
5493 * Added silc_server_relay_packet as general function to relay
5494 packet to arbitrary destination. This deprecates functions
5495 like _send_private_message_key, _relay_notify etc. Affected
5496 file is silcd/packet_send.[ch].
5498 Removed silc_server_send_key_agreement,
5499 silc_server_send_private_message_key and
5500 silc_server_packet_relay_notify functions from the file
5501 silcd/packet_send.[ch].
5505 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5506 server. Affected file silcd/packet_receive.[ch].
5508 * Implemented the KILL command to the client. Implemented the
5509 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5510 Affected files lib/silcclient/command[_reply].c and
5511 lib/silcclient/client_notify.c. Implemented the KILL notify
5512 printing in the user inteface.
5514 * Fixed a lot silc_parse_nick memory leaks from the client
5515 library in the file lib/silcclient/command.c.
5517 * Changed the silc_server_send_notify_on_channels's `sender'
5518 argument from SilcSocketConnection to SilcClientEntry to
5519 check the sender as entry and not as connection object and not
5520 to send to the client provided as argument. The affected file
5521 is silcd/packet_send.[ch].
5523 * The notify packets that are destined directly to the client used
5524 to not to be processed by the server. Now changed that and the
5525 server processes all notify packets. After relaying the packet
5526 to the client the notify packet is processed in the server.
5528 * The silc_server_free_client_data now checks whether there is
5529 pending outgoing traffic for the client and purges the data to
5530 the network before removing the client entry.
5532 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5534 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5535 an client is killed from the SILC Network. Updated the protocol
5538 Added new function silc_server_send_notify_killed to the
5539 silcd/packet_send.[ch].
5541 * Added function silc_server_packet_relay_notify to relay notify
5542 packets that are destined directly to a client. In this case
5543 the server does not process the notify packets but merely relays
5544 it to the client. Affected file silcd/packet_send.[ch].
5546 Added also silc_server_packet_process_relay_notify to check
5547 whereto relay the notify. Affected file is
5548 silcd/packet_receive.[ch].
5550 * Implemented the KILL command to the server.
5554 * Added the backup schema desgined last fall to the protocol
5555 specs for everyone to see. The specification is in the
5556 *-spec-xx.txt draft and the packet type definitions for the
5557 backup routers is in *-pp-xx.txt draft. Thusly, added also
5558 new packet type SILC_PACKET_CELL_ROUTERS.
5560 * A big security problem in the implementation discovered. The
5561 signoff of an client did not cause new channel key generation
5562 which it of course should've done. The channel keys must be
5563 always re-generated when client leaves (or signoffs) the channel.
5564 The silc_server_remove_from_channels funtion now handles
5565 the channel key re-generation.
5567 * Added `sender' argument to the silc_server_send_notify_on_channels
5568 to not to send the client provided as argument. Affected file
5569 silcd/packet_send.[ch].
5571 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5573 * Implemented OPER and SILCOPER commands into the server and
5576 * Added silc_auth_verify and silc_auth_verify_data to verify
5577 the authentication directly from the authentication payload.
5578 It supports verifying both passphrase and public key based
5579 authentication. Affected file lib/silccore/silcauth.[ch].
5581 * Added `hash' field to the SilcIDListData structure. It is the
5582 hash negotiated in the SKE protocol. Affected file is
5585 * Slight redesigning of the SilcAuthPayload handling routines.
5586 Do not send SilcPKCS but SilcPublicKey as argument.
5588 * Implemented the public key authentication support to the
5589 serverconfig. The public key is loaded from the provided path
5590 and saved as authentication data to void * pointer. Thus,
5591 changed the unsigned char *auth_data to void *auth_data;
5593 * Fixed SHUTDOWN command to send the reply before the server
5594 is shutdown. :) Affected file silcd/command.c.
5596 * Fixed fatal bug in CONNECT command. The hostname was invalid
5597 memory and server crashed. Affected file silcd/command.c.
5599 * Fixed fatal bug in CLOSE command. The server_entry became
5600 invalid but was referenced later in the command. Affected file
5603 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5605 * Fixed fatal bug in failure packet handling. Server ignored
5606 the failure and thus crashed when it came.
5610 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5612 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5613 that the command may be executed only once in (about) 2 seconds.
5614 The old SILC_CF_LAG flag is same but allows command bursts up
5615 to five before limiting.
5617 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5618 server code. Various commands now includes the CF_LAG_STRICT
5619 flag to disallow any kind of miss-use of the command.
5621 * Fixed the silc_buffer_unformat to not to allocate any data
5622 if the length of the data is zero. It used to allocate the
5623 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5625 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5627 * Changed the format of AdminConnection configuration section
5628 in the server. Added username of the admin to the format.
5629 Affected files silcd/serverconfig.[ch].
5631 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5632 to return admin configuration data by host, username and/or
5635 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5637 * Implemented WHOWAS command to the server. Added the functions:
5639 silc_server_command_whowas_parse,
5640 silc_server_command_whowas_send_reply,
5641 silc_server_command_whowas_from_client and
5642 silc_server_command_whowas_from_server
5644 * Added <Client ID> argument to the WHOWAS command reply. Updated
5645 the protocol specs accordingly.
5647 * Implemented WHOWAS command and command_reply to the client
5650 Implemented the WHOWAS printing on the user interface.
5652 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Added new argument to the WHOWAS command reply, the real name.
5655 It is an optional argument. Updated the protocol specs.
5657 * Added SilcIDCacheDestructor callback that is registered when
5658 the SilcIDCache is allocated. The callback is called when
5659 an cache entry in the ID Cache expires, or is purged from the
5660 cache. Added into lib/silccore/idcache.[ch].
5662 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5663 to destruct the client entries when the cache entry expires.
5664 Other ID Cache's in server and in the client library ignores
5667 * If the ID Cache entry's `expire' field is zero then the entry
5668 never expires. Added boolean `expire' argument to the
5669 silc_idcache_add function in the lib/silccore/idcache.[ch].
5670 If it is TRUE the default expiry value is used.
5672 * Added silc_server_free_client_data_timeout that is registered
5673 when client disconnects. By default for 5 minutes we preserve
5674 the client entry for history - for WHOWAS command.
5676 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5678 * Added support to the server to enforce that commands are not
5679 executed more than once in 2 seconds. If server receives
5680 commands from client more frequently, timeout is registered
5681 to process the commands. Affected file silcd/command.c.
5682 Added new function silc_server_command_process_timeout.
5684 * Changed NICK_NOTIFY handling in client library to check that
5685 if the client's nickname was changed, so there is no need to
5686 resolve anything from the server.
5688 * Removed error printing from the WHOIS and IDENTIFY commands.
5689 If error occurs then it is ignored silently in the client library.
5690 The application, however, may map the received error to
5691 human readable error string. The application currently maps
5692 the NO_SUCH_NICKNAME error to string.
5694 * Made the command status message public to the application. Moved
5695 them from lib/silcclient/command_reply.c to
5696 lib/silcclient/command_reply.h. The application can map the
5697 received command status to the string with the
5698 silc_client_command_status_message function.
5700 * Added check to the server to check that client's ID is same
5701 as the Source ID in the packet the client sent. They must
5704 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5706 * Added dist-bzip hook to the Makefile.am to make bzip2
5707 compressed distributions.
5709 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5711 * Server now enforces the maximum length for the nickname and
5712 the channel as protocol specification dictates. 128 bytes for
5713 nickname and 256 bytes for channel name.
5715 * Moved the WHOIS printing to the application. The client libary
5716 does not print out the WHOIS information anymore, the application
5717 must do it. Renamed silc_client_command_reply_whois_print to
5718 the silc_client_command_reply_whois_save.
5720 The client's idle time is also sent to the application now, and
5721 the idle is shown on screen.
5723 * Added silc_client_command_reply_identify_save to save the
5724 received IDENTIFY entries.
5726 * Do not check for channel private keys in message sending and
5727 reception if the channel does not have the PRIVKEY mode set.
5728 Affected file lib/silclient/client_channel.c.
5730 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5732 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5733 just surfaced after chaning the JOIN procedure.
5735 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5737 * Added silc_client_get_clients_by_list to get client entries
5738 from Client ID list, that is returned for example by JOIN
5739 and USERS command replies. The application should use this
5740 function for example when JOIN command reply is received to
5741 resolve the clients already on the channel (library does not
5742 do that anymore as USERS command reply is not used in the JOIN
5743 procedure anymore). Affected files lib/silcclient/silcapi.h and
5744 lib/silcclient/idlist.c.
5746 * JOIN command reply and USERS command reply returns now SilcBuffer
5747 pointers instead of unsigned char pointers when returning
5748 the client list and mode list.
5750 * Added <Client ID> argument to the JOIN command reply, mainly
5751 for the server to identify for which client the command was
5752 originally sent. Updated protocol specs accordingly.
5754 * Added SilcDlist private_key pointer to the SilcChannelEntry
5755 in the client to support the channel private keys. Affected
5756 file is lib/silcclient/idlist.h.
5758 * Added SilcChannelPrivateKey argument to the function
5759 silc_client_send_channel_message so that application can choose
5760 to use specific private ke if it wants to. If it is not provided,
5761 the normal channel key is used, unless private keys are set.
5762 In this case the first (key that was added first) is used
5763 as the encryption key.
5765 * Implemented the support for channel private key handling.
5766 Implemented the following functions:
5768 silc_client_add_channel_private_key,
5769 silc_client_del_channel_private_keys,
5770 silc_client_del_channel_private_key,
5771 silc_client_list_channel_private_keys and
5772 silc_client_free_channel_private_keys
5774 Affected file lib/silcclient/client_channel.c.
5776 * Added the support for the private keys in the channel message
5777 sending and encryption and in the message reception and
5778 decryption. Affected funtions are
5779 silc_client_send_channel_message and silc_client_channel_message.
5781 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5783 * Added SKE's key verify callback to the client library's
5784 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5786 * Removed the statement that server (or router) must send USERS
5787 command reply when joining to the channel so that the client
5788 knows who are on the channel. Instead, the client list and
5789 client's mode list is now sent in the JOIN command reply to the
5790 client who joined channel. This is better solution.
5792 * Added function silc_server_get_users_on_channel and function
5793 silc_server_save_users_on_channel to the silcd/server.[ch].
5795 * Removed function silc_server_command_send_users from the
5798 * Do not show topic on the client library anymore. The topic is
5799 sent in the command reply notify to the application and the
5800 application must show the topic now.
5802 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5804 * Added client searching by nickname hash into the IDENTIFY and
5805 WHOIS commands in the server as they were clearly missing from
5806 them. Affected file is silcd/command.c.
5808 * Fixed a bug in private message receiving in the client library.
5809 The remote ID was freed and it wasn't supposed, now it is
5812 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Minor fix to the channel payload; allocate the data area, as it
5815 needs to be of specific length.
5817 * If the key agreement port is zero then the operating
5818 system will define the bound port. Affected files are
5819 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5821 * Added new function silc_channel_payload_decrypt into the file
5822 lib/silccore/silcchannel.[ch].
5824 * Moved the channel message etc, check from silc_packet_decrypt
5825 to applications. The library calls now a generic
5826 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5827 when the packet is either normal or special. This was done to
5828 allow more wide range of checking that was not allowed when
5829 the code was in library. Now applications can do virtually any
5830 checks to the packet and return to the library the decision how
5831 the packet should be processed. Affected files are
5832 lib/silccore/silcpacket.[ch].
5834 Added silc_server_packet_decrypt_check to the server and
5835 silc_client_packet_decrypt_check to the client library.
5837 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5838 to send with specified source and destination information.
5840 * Channel message delivery between routers was broken after the
5841 channel key distribution was fixed earlier. The channel key
5842 was used be to distributed to other routers as well which is not
5843 allowed by the protocol. Now this is fixed and channel keys
5844 really are cell specific and the channel message delivery between
5845 routers comply with the protocol specification.
5847 * Fixed various commands in server to check also the global list
5848 for the channel entry and not just the local list. The affected
5849 file silcd/command.c.
5851 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5853 * Added assert()s to buffer formatting and unformatting routines
5854 to assert (if --enable-debug) when error occurs. Affected
5855 file: lib/silcutil/silcbuffmt.c.
5857 * Changed to auto-reconnect to check whether the remote host is
5858 router and register the re-connect timeout if it is. It used
5859 to check that whether we are normal server, but router must do
5860 auto-reconnect with another router as well. Affected file
5863 * Removed the [<key len>] option from CMODE command as the cipher
5864 name decides the key length, nowadays. See the defined ciphers
5865 from the protocol specification.
5867 * Added [<hmac>] option to the CMODE command to define the HMAC
5868 for the channel. Added SILC_CMODE_HMAC channel mode.
5870 * Added [<hmac>] option for the JOIN command so that user can
5871 select which HMAC is used to compute the MACs of the channel
5874 * Added Hmac field to the Channel Message Payload. The integrity
5875 of plaintext channel messages are now protected by computing
5876 MAC of the message and attaching the MAC to the payload. The
5877 MAC is encrypted. Now, it is clear that this causes some
5878 overhead to the size of the packet but rationale for this is that
5879 now the receiver can verify whether the channel message decrypted
5880 correctly and also when private keys are set for the channel the
5881 receiver can decrypt the packet with several keys and check from
5882 the MAC which key decrypted the message correctly.
5884 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5885 lib/silccrypt/silccipher.[ch].
5887 * Added silc_hash_len to return the digest length into the
5888 lib/silcrypt/silchash.[ch].
5890 * Rewrote parts of Silc Channel Payload interface in the
5891 lib/silccore/silcchannel.[ch]. The encode function now also
5892 encrypts the packet and parse function decrypts it.
5894 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5896 * Fixed a minor formatting bug in the SKE's key material processing.
5897 It actually might have processed the keys wrong way resulting
5900 * Redefined the mandatory HMAC algorithms and added new algorithms.
5901 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5902 and hmac-md5 truncated to 96 bits. The mandatory is now
5903 hmac-sha1-96. Rest are optional (including the one that used
5904 to be mandatory). Rationale for this is that the truncated HMAC
5905 length is sufficient from security point of view and can actually
5906 make the attack against the HMAC harder. Also, the truncated
5907 HMAC causes less overhead to the packets. See the RFC2104 for
5910 * Added new [hmac] configuration section. The SKE used to use
5911 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5912 is of course wrong. The official names that must be proposed in
5913 the SKE are the ones defined in the protocol specification
5914 (hmac-sha1-96 for example). The user can configure any hmac
5915 using any hash function configured in the [hash] section. At
5916 least, the mandatory must be configured.
5918 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5920 * Added HMAC list to the SKE proposal list. It has now both
5921 hash algorithm list and HMAC list. This makes the protocol
5922 incompatible with previous versions. The SKE now seems to work
5923 the way it is supposed to work, for the first time actually.
5925 * Defined plain Hash algorithms to the protocol specification.
5928 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5930 * Implemented support for key agreement packets into the server.
5931 Added functions silc_server_key_agreement and
5932 silc_server_send_key_agreement. Other than these functions,
5933 server has nothing to do with this packet.
5935 * Added support for private message key packets into the server.
5936 Added functions silc_server_private_message_key and
5937 silc_server_send_private_message_key.
5941 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5942 called in the protocol's final callback instead in the END
5943 protocol state. This makes a little more sense and in the same
5944 time in client we can use the same protocol routines for normal
5945 key exchange and to key agreement packet handling as well.
5947 * Added to both client's and server's KE protocol context the
5948 SilcSKEKeyMaterial pointer to save the key material. We will
5949 bring the key material to the protocol's final callback by doing
5950 this. The final callback must free the key material.
5952 * Added SKE's packet_send callback into client's KE protocol
5953 context so that the caller can choose what packet sending function
5954 is used. This way we can use different packet sending when
5955 doing normal SKE when doing key agreement packet handling (in
5956 the key agreement packet handling we do not want to encrypt
5959 * Implemented the responder side of the key agreement routines
5960 in the client. The client can now bind to specified port and
5961 accept incoming key negotiation. The key material is passed
5962 to the application after the protocol is over.
5964 * Implemented the processing of incoming Key Agreement packet
5965 in the client. Added function silc_client_key_agreement to
5968 * Implemented the intiator side of the key agreement routines
5969 in the client. The client can now initiate key agreement with
5970 another remote client. The key material is passed to the
5971 application after the protocol is over.
5973 * Created client_keyagr.c to include all the key agreement
5976 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5977 SILC_TASK_CALLBACK except that it is not static.
5979 * Created client_notify.c and moved the Notify packet handling
5980 from the client.[ch] into that file.
5982 * Created client_prvmsg.c and moved all private message and
5983 private message key routines from the client.[ch] into that file.
5985 * Create client_channel.c and moved all channel message and
5986 channel private key routines from the client.[ch] into that file.
5988 * Changed silc_client_get_client_by_id_resolve to resolve with
5989 WHOIS command instead of IDENTIFY command, in the file
5990 lib/silclient/idlist.c.
5992 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5994 * Implemented the SKE's responder side to the Client library.
5996 * When FAILURE is received to the protocol do not trust it
5997 blindly. Register a timeout to wait whether the remote closes
5998 the connection as it should do it, only after that process the
5999 actual failure. This was changed to both client and server.
6001 * Added client_internal.h to include some of the structures
6002 there instead of client.h in lib/silcclient/.
6004 * Added function silc_task_unregister_by_callback to unregister
6005 timeouts by the callback function.
6007 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6009 * Some "Incomplete WHOIS info" errors has been appearing on the
6010 log files. Took away the entry->userinfo check from WHOIS
6011 reply sending. The entry->userinfo is now " " if client did not
6012 provide one. I thought this was fixed earlier but something
6013 is wrong still. Let's see if the error still appears.
6015 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6017 * Fixed a minor bug in the login when the channel key is
6018 re-generated in the server. It used to generate the key in
6019 wrong order and thus caused problems in the channel traffic.
6021 * Fixed a minor bug in channel key distsribution after
6022 KICK command. The key was not sent to the router even though
6025 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6027 * Added silc_ske_process_key_material_data as generic routine
6028 to process any key material as the SILC protocol dictates. The
6029 function is used by the actual SKE library but can be used by
6030 applications as well. This relates to the private message keys
6031 and the channel private keys since they must be processed the
6032 same way the normal SILC session keys. The protocol dictates
6033 this. Affected files: lib/silcske/silcske.[ch].
6035 Added also silc_ske_free_key_material to free the
6036 SilcSKEKeyMaterial structure.
6038 * Defined silc_cipher_set_key function to set the key for
6039 cipher without using the object's method function. The affected
6040 files: lib/silccrypt/silccipher.[ch].
6042 * Implemented silc silc_client_add_private_message_key,
6043 silc_client_add_private_message_key_ske,
6044 silc_client_del_private_message_key,
6045 silc_client_list_private_message_keys and
6046 silc_client_free_private_message_keys functions in the
6049 Added functions silc_client_send_private_message_key to send
6050 the Private Message Key payload and silc_client_private_message_key
6051 to handle incoming Private Message Key payload.
6053 * Added Cipher field to the Private Message Key payload to set
6054 the cipher to be used. If ignored, the default cipher defined
6055 in the SILC protocol (aes-256-cbc) is used.
6057 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6059 * Removed lib/silcclient/ops.h file.
6061 Redefined parts of the SILC Client Library API. Created new
6062 file silcapi.h that deprecates the ops.h file and defines the
6063 published Client Library API. Defined also private message key
6064 API and channel private key API into the file.
6066 This is the file that the application must include from the
6067 SILC Client Library. Other files need not be included by
6068 the application anymore.
6070 * Added new key_agreement client operation callback and also
6071 defined the Key Agreement library API for the application.
6073 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6075 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6076 is used by clients to request key negotiation between another
6077 client in the SILC network. If the negotiation is started it
6078 is performed using the SKE protocol. The result of the
6079 negotiation, the secret key material, can be used for example
6080 as private message key.
6082 Implemented the Key Agreement payload into the files
6083 lib/silccore/silauth.[ch].
6085 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * Redefined ciphers for the SILC protocol. Added some new ciphers
6088 and defined the key lengths for the algorithms. Changed the
6089 code accordingly. The default key length is now 256 bits.
6091 * Fixed SKE key distribution function silc_ske_process_key_material
6092 when the key length is more than 128 bits. The default key
6093 length in SILC is now 256 bits.
6095 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6096 to indicate unsupported algorithm.
6098 * Renamed rijndael.c to aes.c and all functions as well.
6100 * Fixed a long standing channel key setting bug in client library.
6101 Weird that it has never surfaced before.
6103 * Fixed bug in channel deletion. If the entire channel is removed
6104 then it must also delete the references of the channel entry
6105 from the client's channel list as the client's channel entry and
6106 the channel's client entry share same memory.
6108 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6110 * Implemented CONNECT and SHUTDOWN commands in the client.
6112 * Implemented CLOSE command to the client.
6114 * Added the function silc_idlist_find_server_by_name into the
6115 files silcd/idlist.[ch].
6117 Added the function silc_idlist_find_server_by_conn into the
6118 files silcd/idlist.[ch].
6120 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6122 * DIE command was renamed to SHUTDOWN. Updated the both code
6125 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6126 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6128 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6131 * Added function silc_server_create_connection function to create
6132 connection to remote router. My server implementation actually
6133 does not allow router to connect to normal server (it expects
6134 that normal server always initiates the connection to the router)
6135 so the CONNECT command is only good for connecting to another
6138 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6141 or some other client was kicked from the channel.
6143 Implemented the handling of the notify type to both client
6146 Implemented silc_server_send_notify_kicked to send the KICKED
6147 notify. It is used to send it to the server's primary router.
6149 * Implemented the KICK command into server and client.
6151 * Added `query' argument to the silc_idlist_get_client function
6152 to indicate whether to query the client from server or not if
6155 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6156 to indicate that the client is not channel founder.
6160 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6162 * Removed the rng context from SilcPacketContext structure and
6163 changed that the packet routine uses the Global RNG API.
6165 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6167 * Added support for quit message that client can "leave" on the
6168 channel when it quits the SILC. It is ditributed inside the
6169 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6171 Added silc_server_free_client_data that will take the
6172 signoff message as argument.
6174 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6176 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6178 * Updated parts of the protocol specification to keep it up
6181 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6183 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6184 payloads in one packet.
6186 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6187 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6188 use now the new List flag.
6190 * Also deprecated the following packet types: REPLACE_ID,
6191 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6193 * Added list support for Notify packet in server.
6195 * Added silc_server_send_notify_channel_change to send the
6196 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6197 the silc_server_send_replace_id.
6199 * Added silc_server_send_notify_nick_change to send the
6200 NICK_CHANGE notify type. Deprecates the function
6201 silc_server_send_replace_id.
6203 * Added silc_server_send_notify_join to send the JOIN notify type.
6204 Deprecates the function silc_server_send_new_channel_user.
6206 * Added silc_server_send_notify_leave to send LEAVE notify type.
6207 Deprecates the function silc_server_send_remove_channel_user.
6209 * Added silc_server_send_notify_cmode and
6210 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6211 types. Deprecates the silc_server_send_set_mode function.
6213 * Added SERVER_SIGNOFF notify type to indicate that server has
6214 quit. This means that all clients on the channel from that
6215 server will drop. This can be also used when netsplit happens.
6217 Deprecated REMOVE_ID packet type since it is not needed anymore
6220 Added silc_server_send_notify_server_signoff to send the
6221 SERVER_SIGNOFF notify type. Deprecates the function
6222 silc_server_send_remove_id.
6224 Added also silc_server_send_notify_signoff to send the
6225 SIGNOFF notify type.
6227 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6228 SILC protocol from this day on. Changed the protocol
6229 specification as well.
6231 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6232 notify type. It is used between routers to notify about
6233 topic changes on a channel.
6235 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6238 * Partly updated the protocol specification to comply with the
6239 changes now made. It is still though a bit outdated.
6241 * The JOIN notify type now takes one extra argument <Channel ID>.
6242 The packet used to be destined to the channel but now the
6243 JOIN type may be sent as list thus it is impossible to
6244 destine it to any specific channel. By adding this argument
6245 it is again possible.
6247 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6249 * Added CREDITS file. The CHANGES and CREDITS file will appear
6250 in the distribution as well.
6252 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6254 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6255 types in the server's silcd/packet_receive.c.
6257 * Implemented CMODE and CUMODE to work in router environment.
6259 * Fixed minor encoding and decoding buglet from the
6260 lib/silccore/silcmode.c.
6262 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6265 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6267 * Changed all SilcConfigServer* and silc_config_server* to
6268 SilcServerConfig* and silc_server_config*, respectively.
6271 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6273 * Associated the ID (client or server ID) to the Authentication
6274 Payload to avoid any possibility of forging. Updated the
6275 protocol specification and the code accordingly.
6277 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6279 * The RSA key length is now save to the RsaKey context in the
6280 key generation process in lib/silccrypt/rsa.c. The key length
6281 is now used to figure out the maximum size of the block allowed
6282 to be encrypted/signed.
6284 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6285 is equivalent to the silc_mp_mp2bin but does not allocate any
6288 * Changed silc_mp_mp2bin API to take length argument. If it is
6289 non-zero then the buffer is allocated that large. If zero, then
6290 the size is approximated using silc_mp_sizeinbase, which however
6293 * Created Global RNG API which is global RNG that application can
6294 initialize. After initializing, any routine anywhere in the
6295 code (including library) can use RNG without allocating a new
6296 RNG object. This was done to allow this sort of use of the
6297 RNG in code that has no chance to allocate RNG object. All
6298 applications currently allocate this and many routines in the
6299 library use this. Affected file lib/silccrypt/silcrng.[ch].
6301 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6302 it to use the Global RNG API.
6304 * Defined Authentication Payload into protocol specification that
6305 is used during SILC session to authenticate entities. It is
6306 used for example by client to authenticate itself to the server
6307 to obtain server operator privileges.
6309 Implemented this payload into the lib/silccore/silcauth.[ch].
6310 Implemented also routines for public key based authentication
6311 as the new protocol specification dictates.
6313 Moved definitions of different authentication methods from
6314 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6316 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6317 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6318 silc_pkcs_verify_with_hash functions into the file
6319 lib/silccrypt/silcpkcs.[ch].
6321 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6323 * The client entry's userinfo pointer must be always valid.
6324 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6325 will fail since it requires the userinfo. Now, the userinfo
6326 is allocated as "" if actual userinfo does not exist. Actually,
6327 it must exist and it is totally Ok to drop client connections
6328 that does not announce the userinfo. However, we will make
6329 this workaround for now.
6331 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6332 to return the remote port by socket.
6334 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6336 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6337 SILC_SERVER_PENDING_EXEC and added an new macro
6338 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6339 data or when error occurs while processing the pending command.
6341 Added new argument `destructor' into silc_server_command_pending
6342 and to the SilcServerCommandPending object. This destructor is
6343 now called after calling the pending callback or if error occurs
6344 immediately. If error occurs the actual pending callback won't
6345 be called at all - only the destructor. The destructor may be
6346 NULL if destructor is not needed.
6348 All this applies for client library code as well. Similar
6349 changes were made there as well for the pending commands.
6351 In the client, the application must now allocate the
6352 SilcClientCommandContext with the silc_client_command_alloc
6355 * Added reference counter to the SilcServerCommandContext. Added
6356 function silc_server_command_alloc and silc_server_command_dup
6359 Same type of functions added to the client library for the same
6362 * Removed the cmd_ident from IDListData away since it is now
6363 global for all connections. It is the command identifier used
6364 in command sending and with pending commands. The affected file
6367 * Added reference counter to the SilcSocketConnection objecet to
6368 indicate the usage count of the object. The object won't be
6369 freed untill the reference counter hits zero. Currently only
6370 server uses this, and client ignores it. The client must be
6371 set to use this too later. The affected files are
6372 lib/silccore/silcsockconn.[ch]. Added also the function
6373 silc_socket_dup to increase the reference counter.
6375 This was mainly added because it is possible that the socket
6376 is removed underneath of pending command or other async
6377 operation. Now it won't be free'd and proper DISCONNECTING
6378 flags, etc. can be set to avoid sending data to connection that
6379 is not valid anymore.
6381 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6382 the connection. After that it sets SILC_SET_DISCONNECTED.
6383 It is, however, possible that the socket data is not still freed.
6384 The silc_server_packet_process now checks that data is not
6385 read or written to connection that is DISCONNECTED. The socket
6386 get's freed when the reference counter hits zero.
6388 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6390 * Changed the client operation API: channel_message operation's
6391 `sender' is now the client entry of the sender, not the nickname
6392 and the `channel' is the channel entry, not the channel name.
6394 In the private_message operation the `sender' is now also the
6395 client entry of the sender not the nickname.
6397 Affected file is lib/silcclient/ops.h and all applications
6398 using the client operations.
6400 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6402 * Moved the calling of ops->connect() from connect_to_server_final
6403 into receive_new_id functin since that is the point when the
6404 client is actually allowed to send traffic to network. The
6405 affected file is lib/silcclient/client.c.
6407 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6409 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6410 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6411 (if needs broadcasting) instead of broadcasting the packets one
6412 by one which would make a burst in the network traffic.
6414 * Added `broadcast' argument to the functions in silcd/server.[ch]
6415 silc_server_create_new_channel[_with_id] to indicate whether
6416 to send New Channel packet to primary router.
6418 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6420 * Added new function into the silcd/server.[ch] files:
6421 silc_server_create_new_channel_with_id to create new channel with
6422 already existing Channel ID.
6424 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6425 lib/silccore/silcpacket.h. This packet is used t send list of
6426 Set Mode payloads inside one packet. Server uses this to set
6427 the modes for the channels and clients on those channels, that it
6428 announced to the router when it connected to it. The protocol
6429 specification has been updated accordingly.
6431 * The silc_server_new_channel did not handle the packet coming
6432 from normal server as it normally does not send that. However,
6433 when it announces its channels it does send it. Implemented
6434 the support for that.
6436 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6437 into the file lib/silccore/id.h.
6439 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * Fixed memory leaks in the functions silc_idlist_del_client,
6442 silc_idlist_del_channel and silc_idlist_del_server in the file
6443 silcd/idlist.c. All of those leaked like a sieve.
6445 * Fixed some small memory leaks in the client's function
6446 silc_client_notify_by_server.
6448 * Added functions into silcd/server.c: silc_server_announce_clients,
6449 silc_server_announce_channels and silc_server_announce_server.
6450 These functions are used by normal and router server to announce
6451 to its primary router about clients, channels and servers (when
6452 router) that we own. This is done after we've connected to the
6455 These functions effectively implements the following packet types:
6456 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6457 and SILC_PACKET_NEW_ID_LIST.
6459 * Added new functions into the silcd/packet_receive.[ch]:
6460 silc_server_new_id_list, silc_server_new_channel_list and
6461 silc_server_new_channel_user_list to handle the incoming
6462 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6464 * Added support of changing Channel ID in the function
6465 silc_server_replace_id. If the server that announces a channel
6466 to the router already exists in the router (with same name but
6467 with different Channel ID), router is responsible to send
6468 Replace ID packet to the server and force the server to change
6469 the Channel ID to the one router has.
6471 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6472 client that the Channel ID has been changed by the router. The
6473 normal server sends this to the client. Client must start using
6474 the new Channel ID as the channel's ID.
6476 Implemented handling of this new type into lib/silcclient/client.c
6477 into the function silc_client_notify_by_server.
6479 * Added new function silc_idlist_replace_channel_id into the files
6480 silcd/idlist.[ch] to replace the Channel ID.
6482 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6484 * Call silc_server_command_identify_check always when processing
6485 the IDENTIFY command in silcd/command.c
6487 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6489 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6490 send keepalive packets. The packet can be sent by clients,
6491 servers and routers.
6493 Added function silc_socket_set_heartbeat into the file
6494 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6495 If not set, the heartbeat is not performed. The actual
6496 heartbeat is implemented in the low level socket connection
6497 library. However, application is responsible of actually
6500 Added silc_server_send_heartbeat to send the actual heartbeat
6501 packet into silcd/packet_send.[ch]. Server now performs
6502 keepalive with all connections.
6504 * Added silc_task_get_first function into lib/silcutil/silctask.c
6505 to return the timeout task with shortest timeout. There was a bug
6506 in task unregistration that caused problems. TODO has been
6507 updated to include that task system must be rewritten.
6509 * The client library will now resolve the client information when
6510 receiving JOIN notify from server for client that we know but
6511 have incomplete information.
6513 * Rewrote parts of silc_server_remove_from_channels and
6514 silc_server_remove_from_one_channel as they did not remove the
6515 channel in some circumstances even though they should've.
6517 * Encryption problem encountered in server:
6519 The LEAVE command used to send the Channel Key packet to the
6520 router immediately after generating it. However, the code
6521 had earlier sent Remove Channel user packet but not immediately,
6522 ie. it was put to queue. The order of packets in the router
6523 was that Channel Key packet was first and Remove Channel User
6524 packet was second, even though they were encrypted in the
6525 reverse order. For this reason, MAC check failed. Now, this
6526 is fixed by not sending the Channel Key packet immediately but
6527 putting it to queue. However, this is more fundamental problem:
6528 packets that are in queue should actually not be encrypted
6529 because packets that are sent immediately gets encrypted
6530 actually with wrong IV (and thus MAC check fails). So, packets
6531 that are in queue should be encrypted when they are sent to
6532 the wire and not when they put to the queue.
6534 However, the problem is that the current system has not been
6535 designed to work that way. Instead, the packet is encrypted
6536 as soon as possible and left to the queue. The queue is then
6537 just purged into wire. There won't be any fixes for this
6538 any time soon. So, the current semantic for packet sending
6541 o If you send packet to remote host and do not force the send
6542 (the packet will be in queue) then all subsequent packets to the
6543 same remote host must also be put to the queue. Only after the
6544 queue has been purged is it safe again to force the packet
6547 o If you send all packets immediately then it safe to send
6548 any of subsequent packets through the queue, however, after
6549 the first packet is put to queue then any subsequent packets
6550 must also be put to the queue.
6552 Follow these rules and everything works fine.
6554 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6556 * Added new function silc_server_remove_clients_by_server to
6557 remove all client entries from ID list when the server connection
6558 is lost. In this case it is also important to invalidate all
6559 client entires as they hold the invalid server entry. This
6560 fixes fatal bug when server has lost connection and will reconnect
6563 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6565 * Made some sanity checks to silc_server_daemonise like to check
6566 whether the requested user and group actually exists.
6568 * Added sanity check to SKE's silc_ske_responder_finish to check
6569 that the public and private key actually is valid.
6571 * Invalidate the client's nickname when receiving Replace ID
6572 packet and the Client ID is being replaced. This means that the
6573 server will query the nickname if someone needs it (client)
6576 * Sort the ID Cache in client library when the ID Cache data
6577 has changed (needs sorting).
6579 * Do not allow for SILC client to create several connections to
6580 several servers. The client does not support windows right now
6581 and generating multiple connections causes weird behaviour.
6583 Irssi-silc client does support windows and can handle several
6584 connections without problems, see: www.irssi.org and SILC plugin.
6586 * Fixed some places where client was added to the IDList. The
6587 rule of thumb is following (in order to get everything right):
6588 If the client is directly connected local client then the
6589 `connection' argument must be set and `router' argument must be
6590 NULL to silc_idlist_add_client function. If the client is not
6591 directly connected client then the `router' argument must
6592 bet set and the `connection' argument must be NULL to the
6593 silc_idlist_add_client function.
6595 * The funtion silc_server_packet_send_local_channel actually did
6596 not check whether the client was locally connected or not. It
6597 does that now. Fixed a bug related to LEAVE command.
6599 * Fixed Remove Channel User payload parsing bug in server's
6600 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6602 * The server's silc_server_save_channel_key now checks also the
6603 global ID list for the channel as it might not be in the local
6604 list. Fixed a bug related to LEAVE command.
6606 * Is this the end of the [<unknown>] buglet that has been lurking
6607 around for a long time? A little for loop fix in server's
6608 silc_server_command_whois_parse that is used by both IDENTIFY
6609 and WHOIS command. At least, this was a clear bug and a cause
6610 of one type of [<unknown>] buglet.
6612 * WHOIS and IDENTIFY commands call the function
6613 silc_server_command_[whois/identify]_check function even if
6614 we are not router server.
6616 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6618 * Added --with-gmp configuration option. If set the GMP
6619 is always compiled in the SILC source tree. If not set then
6620 it is checked whether the system has the GMP3 installed. If
6621 it has then the GMP won't be compiled (the system's headers
6622 and library is used), if it doesn't have it then the GMP is
6623 compiled in the SILC source tree.
6625 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6627 * Changed RSA private exponent generation to what PKCS #1
6628 suggests. We try to find the smallest possible d by doing
6629 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6630 not security fix but optimization.
6632 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6634 * Added new config entry [Identity] to fork the server and run
6635 it as specific user and group. A patch from Bostik.
6637 * Imported Dotconf configuration library into lib/dotconf.
6638 This will be used to create the SILC configuration files later.
6639 It will appear in the distsribution after this commit.
6641 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6643 * A big code auditing weekend happening. Auditing code for
6644 obvious mistakes, bugs and errors. Also, removing any code
6647 Removed files for being obsolete:
6649 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6650 inline in the file lib/silcutil/silcbuffer.h)
6652 o lib/silcutil/silcbufutil.c (the header has inline versions)
6654 Changed code to fix possible error conditions:
6656 o The buffer formatting routines now check that the destination
6657 buffer really has enough space to add the data. This applies for
6658 both buffer formatting and unformatting
6659 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6660 unformatting was changed to accomodate following rules:
6661 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6662 sent to the function while XXX_*STRING will not allocate or copy
6663 the data into the buffer. Instead it sets the pointer from the
6664 buffer into the pointer sent as argument (XXX_*STRING used to
6665 require that the pointer must be allocated already). This change
6666 makes this whole thing a bit more consistent and more optimized
6667 (note that the data returned in the unformatting with XXX_*STRING
6668 must not be freed now). The routines return now -1 on error.
6670 o Tried to find all code that use buffer_format and buffer_unformat
6671 and added return value checking to prevent formatting and
6672 especially unformatting errors and possible subsequent fatal
6675 o Changed ske->x and ske->KEY to mallocated pointers in
6676 lib/silcske/silcske.h. Fixed possible data and memory leak.
6678 o Added return value checking to all *_parse* functions. Fixed
6679 many memory leaks as well.
6681 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6682 so that buffer overflows would not happen. All code now also
6683 checks the return value as it can fail.
6685 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6687 * Added reconnection support to server if the normal server looses
6688 its connection to the router (for example if router is rebooted).
6689 The server performs normal reconnection strategy implemented
6690 to the server. Affected file silcd/server.c.
6692 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6694 * Added new packet type SILC_PACKET_SET_MODE that is used to
6695 distribute the information about changed modes (for clients,
6696 channels and clients channel modes) to all routers in the
6697 network. Updated the protocol specification accordingly.
6699 Added functions into silcd/packet_send.c and
6700 silcd/packet_receive.c: silc_server_send_set_mode,
6701 silc_server_set_mode.
6703 Added new files silcmode.[ch] into lib/silccore that implements
6704 the encoding and decoding of Set Mode Payload. Added new type
6705 SilcSetModePayload. Moved the definitions of different modes
6706 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6708 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6710 * Oops, a little mistake in server's connection authentication
6711 protocol. The protocol is not ended with FAILURE but with
6712 SUCCESS if the authentication is Ok. :) Affected file is
6715 * Implemented NICK_CHANGE notify handling in server in the file
6716 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6717 the local clients on the channel. After the changing nickname
6718 in router environment snhould work and the [<unknown>] nickname
6719 should appear no more.
6721 The silc_server_replace_id function that receives the Replace ID
6722 payload now sends the NICK_CHANGE notify type also in the file
6723 silcd/packet_receive.c
6725 * Changed WHOIS and IDENTIFY command to support the maximum amount
6726 of arguments defined in protocol specs (3328 arguments). This
6727 fixed a bug that caused problems when there were more than three
6730 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6732 * Added extra parameter, command identifier, to the
6733 silc_client_send_command so that explicit command identifier
6736 Changed that ID list routines uses specific command identifier
6737 when sending WHOIS/IDENTIFY requests to the server so that they
6738 can be identified when the reply comes back.
6740 Affected files lib/silcclient/command.[ch],
6741 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6743 * Added `sender' argument to silc_server_packet_send_to_channel
6744 to indicaet the sender who originally sent the packet to us
6745 that we are now re-sending. Ignored if NULL. Affected file
6746 silcd/packet_send.[ch].
6748 * Added some server statistics support in silcd/server_internal.h
6749 SilcServerStatistics structure and around the server code. Also
6750 send some nice statistics information when client is connecting
6753 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6755 * Fixed channel ID decoding in server's JOIN command reply in
6756 silcd/command_reply.c
6758 * Fixed braodcasting of replace ID payload to not to send it if
6759 we are standalone server in silcd/packet_receive.c.
6761 * Fixed all channel message sending routines to not to send
6762 packets to clients that has router set, since they are routed
6763 separately in the same function earlier. Affects file
6764 silcd/packet_send.c and all channel packet sending functions.
6766 * In USERS reply, res_argv[i] are not allocated, the table
6767 is allocated. Thus changed that free the table, not its
6770 * In server's whois_check and identify_check if the client is
6771 locally connected do not send any WHOIS commands - they are not
6774 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6776 * Fixed some minor bugs in client when sending WHOIS command. The
6777 arguments was in wrong order.
6779 * Removed statis function add_to_channel from server in
6780 silcd/command.c that was previously used with the joining but
6783 * Tested USERS command in router environment successfully with two
6784 routers, two servers and two clients.
6786 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6788 * Reorganized the USERS command and command reply in client library
6789 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6790 When the command is given by user we register a pending command
6791 callback that will reprocess the command after the reply has been
6792 received from the server. When reprocessing the packet we then
6793 display the information. Thus, the USERS information is displayed
6794 now in the command callback instead of in the command reply
6795 callback. The processing of the command is same as previously
6796 when server has sent the command reply in the JOINing process.
6798 * Added to USERS command in silcd/command_reply.c to join the client,
6799 we didn't use to know about, to the channel after we've created
6800 a client entry for it. Also, for clienet we did know already still
6801 check whether it is on the channel or not and add it if not.
6803 * Removed silc_server_command_join_notify as the function and its
6806 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6808 * Changed the client's pending command handling to the same as the
6809 server's pending command handling. It is also now possible to
6810 execute command reply functions from other command reply
6811 function as the function callbacks for commands and command
6812 replies are one and same. The pending commands are not static
6813 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6814 in client connection context. Thus, pending commands are server
6815 connection specific as it is convenient.
6817 Changed the function silc_client_command_pending and
6818 silc_client_command_pending_del and added new function
6819 silc_client_command_pending_check. Removed the
6820 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6823 * Added cmd_ident, current command identifier, to the client
6824 connection context in lib/silcclient/client.h to keep track on
6825 command identifiers used in command sending. Client's command reply
6826 function handling now supports the mandatory command identifiers.
6828 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6829 funtions in client to fully support pending command callbacks.
6831 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6832 as one of the arguments to the application in the command reply
6835 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6836 before first releasing SILC but came back. Now it is removed again
6837 and should come back nomore. The FORWARDED flag was used only
6838 by the JOINing procedure by forwarding the command packet to router.
6839 Now, the JOINing procedure has been changed to more generic (due
6840 to various router environment issues) and FORWARDED is not needed
6841 anymore for anything. The protocol specification is yet to be
6844 Now, removed silc_server_packet_forward from server and the flag
6845 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6847 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6849 * Renamed NAMES command to USERS command. The NAMES was named that
6850 due to historical reasons. Now it is renamed. Also, rewrote
6851 parts of the USERS command. The nickname list is not sent anymore
6852 by the server. Only Client ID and mode lists are sent in the USERS
6853 command. Changed this also to the protocol specification.
6855 The client now resolves the names and stuff after it receives
6856 the USERS list from the server when joining to the channel.
6858 * WHOIS and IDENTIFY commands has been changed to support multiple
6859 Client ID's per command. One can now search for multiple users
6860 in the network by sending only one WHOIS or IDENTIFY command.
6861 Changed the code and the protocol specifications.
6863 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6864 uses silc_server_command_whois_parse to parse the request. */
6866 * If normal server, do not parse the WHOIS and IDENTIFY requests
6867 before sending it to the router. Saves some time.
6869 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6871 * Fixed JOIN command on client library. Wrong number of arguments
6872 used to crash the client.
6874 * Added silc_server_channel_has_global function to check whether
6875 channel has global users or not.
6877 * Added silc_server_channel_has_local function to check whether channel
6878 has locally connected clients on the channel.
6880 * The silc_server_remove_from_one_channel now checks whether the
6881 channel has global users or not after given client was removed from
6882 the channel. It also checks whether the channel has local clients
6883 on the channel anymore. If it does not have then the channel entry
6884 is removed as it is not needed anymore.
6886 * The silc_server_notify now checks on JOIN notify whether the joining
6887 client is one of locally connected or global. If it is global then
6888 the channel has now global users on the channel and that is marked
6889 to the channel entry. Also, it now saves the global client to
6890 global list who is joining and JOINs it to the channel. This is
6891 for normal server, that is.
6893 Changed silc_server_send_notify_on_channel,
6894 silc_server_packet_relay_to_channel and
6895 silc_server_packet_send_to_channel check if we are normal server
6896 and client has router set (ie. global client) do not send the
6897 message to that client, as it is already routed to our router.
6899 * Implemented LEAVE notify type handling in silc_server_notify
6902 * Tested LEAVE command in router environment successfully. Tested
6903 with two routers, two servers and two clients.
6907 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6909 * Implemented SIGNOFF notify type handling in silc_server_notify
6912 * silc_server_remove_id now removes the client entry from all channels
6913 it has joined and thusly sends SIGNOFF notify type.
6915 * Rewrote the NAMES list generation in server by removing two excess
6916 loops. The lists are created now inside one loop.
6918 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6920 * silc_server_remove_channel_user checks now also global list
6921 for channel and client.
6923 * silc_server_new_channel_user checks now both local and global
6924 list for channel and client. Fixed a bug in client id decoding.
6925 Used to decode wrong buffer.
6927 * silc_server_channel_message checks now both local and global
6928 list for channel entry.
6930 * Tested channel joining (hence JOIN) in router environment
6931 successfully. Tested with two routers, two servers and two
6934 * Tested channel message sending in router environment successfully.
6936 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6938 * Added silc_server_save_channel_key into server.[ch] to save the
6939 received channel key in Channel Key payload processing. It is
6940 also used in JOIN command reply handling.
6942 Equivalent function silc_client_save_channel_key added into
6943 client.[ch] into client library.
6945 * Changed JOIN command reply to send information whether the channel
6946 was created or not (is existing already) and the channel key
6947 payload. Changed protocol specs accordingly.
6949 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6950 the request was sent by ID and not by nickname. Crashed on
6953 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6955 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6956 now correctly save the received data.
6958 * silc_server_free_sock_user_data now notifies routers in the
6959 network about entities leaving the network.
6961 At the same time implemented functions silc_server_remove_id
6962 and silc_server_send_remove_id to receive and send REMOVE_ID
6963 packets. The packet is used to notify routers in the network
6964 about leaving entities. The ID removed will become invalid in
6967 * Added function silc_idlist_del_server into server. Removes and
6968 free's server entry from ID list.
6970 * silc_server_private_message function now checks, if we are router,
6971 that the destination ID really is valid ID, naturally.
6973 * In router when NEW_ID packet is received (for new client) the
6974 hash of the Client ID is saved in the ID Cache but the
6975 client->nickname is set to NULL, instead of putting the hash
6978 IDENTIFY command now also checks that client->nickname must be
6979 valid. If it is not if will request the data from the server who
6980 owns the client. Added new function
6981 silc_server_command_identify_check.
6983 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6984 to set the command to already allocated Command Payload.
6986 * Tested private message sending in router environment with two
6987 routers, two servers and two clients. Fixed minor bugs and now
6990 * Fixed segfault from client's NAMES command. Used to crash if
6993 * Forwarded packets must not be routed even if it is not destined
6994 to the receiver. Changed server code comply with this.
6996 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6998 * Added `require_reverse_mapping' boolean value to ServerParams
6999 structure. If TRUE (not default) the server will require that
7000 the connecting host has fully qualified domain name.
7002 If the reverse mapping is not required and hostname could not be
7003 found the IP address is used as hostname.
7005 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7007 * Implemented version string checking to both client and server.
7008 The check is incomplete currently due to the abnormal version
7009 strings used in development version of SILC.
7011 * Changed all command functions in server to use the new
7014 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7016 * Changed char *data to unsigned char *data in ID Cache system to
7017 support binary data as ID Cache data. Changed code to support
7018 binary data in lib/silccore/idcache.c.
7020 * Renamed silc_server_packet_relay_command_reply to
7021 silc_server_command_reply as it is normal packet receiving
7022 function. Rewrote the function to accept command replys for
7023 servers and not only for clients.
7025 * Mark remote router always as registered server if we are connecting
7026 to it. Otherwise, commands sent by the router to us are ignored.
7028 * All ID List find routines now returns the ID Cache Entry pointer
7029 as well if requested.
7031 * WHOIS command works now in router environment, tested with two
7032 routers, two servers and two clients.
7034 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7035 in router environment (as it is almost equivalent to WHOIS) but
7036 hasn't been tested thoroughly. Added new functions:
7038 silc_server_command_identify_parse
7039 silc_server_command_identify_send_reply
7040 silc_server_command_identify_from_client
7041 silc_server_command_identify_from_server
7043 * Disabled route cache adding because adding two different ID's with
7044 same IP replaces the old cache entry thus giving wrong route.
7045 The entry->router->connection is always the fastest route anyway
7046 so route cache may not be needed. Of course, new routes maybe
7047 established after receiving the ID when the entry->router->connection
7048 might not be anymore the most optimal.
7050 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7052 * Add route cache for received ID for fast routing.
7054 * Added silc_server_packet_route to route received packet on router
7055 that is not destined to us.
7057 * Renamed silc_server_get_route to silc_server_route_get.
7059 * Added id_string and id_string_len fields into SilcServer to
7060 include encoded ServerID for fast comparing without excess
7061 encoding of the ID's.
7063 * Cleaned up WHOIS command on server side. Added following static
7066 silc_server_command_whois_parse
7067 silc_server_command_whois_check
7068 silc_server_command_whois_send_reply
7069 silc_server_command_whois_from_client
7070 silc_server_command_whois_from_server
7072 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7073 arguments in command replies. All command functions should be
7074 updated to use this macro.
7076 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7078 * Minor typo fixes on command reply handling on server.
7080 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7082 * Added silc_server_command_add_to_channel internal routine to add
7083 the client to the channel after router has created the channel and
7084 sent command reply to the server.
7086 * Added generic silc_server_send_command to send any command from
7089 * Use static buffer with ID rendering instead of duplicating data.
7091 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7093 * Fixed a channel user mode bug when joining to a channel server gave
7094 everybody channel founder rights, oops.
7096 * We mark ourselves as the router of the incoming server connection
7097 if we are router ourselves. This way we can check in some packet
7098 sending functions whether it is locally connected server. For
7099 incoming router connections we put NULL.
7101 * For router sending packets locally means now always sending the
7102 packet cell wide; to local clients and local servers. For normal
7103 server sending packet locally means sending it to only local
7106 * Fixed the JOIN command to really work in router environment. If the
7107 channel is created it is always created by the router. Router is
7108 also responsible of making the initial joining to the channel,
7109 sending JOIN notify to the sending server and distributing
7110 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7111 does not exist server doesn't do anything else but forward the
7112 command to the router which performs everything.
7114 * Added silc_server_send_channel_key function to send the Channel Key
7117 * Added silc_server_create_channel_key to create new channel key. The
7118 channel key is now re-generated everytime someone joins or leaves
7119 a channel, as protocol dictates. Note: channel->key_len is the
7122 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7124 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7125 packet_receive.[ch] to separate packet sending and receiving
7126 routines. The server.[ch] now includes everything else including
7127 actual packet processing (writing and reading data) and other
7130 Renamed silc_server_private_message_send_internal to
7131 silc_server_send_private_message. The routine is still though
7132 used only to relay private messages as server does not send
7133 private messages itself.
7135 Renamed silc_server_new_channel to silc_server_create_new_channel
7136 and added new function sicl_server_new_channel that handles the
7137 incoming New Channel packet. Added also new sending function
7138 silc_server_send_new_channel to send New Channel Payload.
7140 * Added new function silc_server_notify to process incoming notify
7141 packet to the server/router. Server may then relay the notify
7142 to clients if needed.
7144 * Added new function silc_server_new_channel_user to process incoming
7145 New Channel User packet. Router will redistribute the packet and
7146 send JOIN notify to its local clients and locally connected servers
7147 if needed. Normal server will send JOIN notify to its local client
7148 on same channel when received this packet. Added also corresponding
7149 sending function silc_server_send_new_channel_user to sent the
7152 * Added boolean route argument to send_notif_to_channel and
7153 packet_send_to_channel functions to attempt to route the packet
7154 if it is TRUE and send only locally if it is FALSE.
7156 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7158 * silc_server_replace_id now broadcasts the received replace ID
7159 packet if it is not broadcast packet already. The router must
7160 broadcast to inform other routers about changed ID.
7162 * Added backpointer to server's router into SilcServer context in
7163 silcd/server_internal.h.
7165 * Fixed silc_server_packet_broadcast to send correct broadcast
7168 * The channel key is now distributed to the local client as soon
7169 as it is received from the router (in router environment) so that
7170 no other packet may be sent for the channel until client has
7173 * silc_server_remove_channel_user now broadcasts the received
7174 Remove Channel User packet if it is not broadcast packet already.
7175 The router must broadcast to inform other routers about removed
7178 * Added users field into SilcPacketContext that is a reference count
7179 of the context. One can increase the reference count by calling
7180 silc_packet_context_dup which is now changed to just increase the
7181 reference count instead of duplicating the data. The reference
7182 count is decresed by calling silc_packet_context_free that will
7183 free the data after the reference count hits zero.
7185 For now on the packet context and everything allocated into it
7186 (including the raw packet from network) must be freed by calling
7187 the new silc_packet_context_free function. Added also new function
7188 silc_packet_context_alloc that must be used now to allocate the
7189 context. This also means that if a routine is asynchronous from
7190 silc_[client/server]_packet_parse_type the packet context must
7191 be duplicated by calling silc_packet_context_dup. Otherwise it
7192 gets free'd after silc_[client/server]_packet_parse_type returns.
7193 Also, one must remember that if packet is duplicated then its
7194 reference count must be decresed by calling the free function as
7195 many times as it was duplicated.
7197 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7198 from both client and server.
7200 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7202 * Made joining to a channel working in router environment.
7204 * Cleaned up JOIN command on server side and create function
7205 silc_server_command_join_channel internal routine to make the
7208 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7210 * Changed silc_command_pending list to SilcDList. Also, added
7211 `ident' field to SilcServerCommandPending structure to identify
7212 the reply and to call correct callback.
7214 Added silc_server_command_pending_check function to replace the
7215 corresnponding macro. The silc_command_pending list is not
7218 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7219 to set identifier to previously allocated Command Payload. It
7220 is used to set identifier for command when resending Command
7223 * Added silc_command_payload_encode_payload to encode Command
7224 Payload buffer from SilcCommandPayload structure.
7226 * Added silc_argument_payload_encode_payload to encode Argument
7227 payload buffer from SilcArgumentPayload structure.
7229 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7231 * Changed WHOIS command to support router connection on server side.
7232 The whois request is always sent to router unless the server is
7233 standalone server. After server has received the reply from the
7234 router will it send the reply to the client.
7236 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7237 broadcast received broadcast packet. The function is used only
7238 by router. The broadcast packet is always sent to the router's
7241 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7242 render given ID to printable string, for log files for example.
7244 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7246 * Made basic router to router connections working. At least they
7247 can now connect to each other but nothing really works the way
7248 they are supposed - yet.
7250 * Added new initiator token to RouterConnection configuration
7251 file in silcd/serverconfig.[ch]. It is used to tell whether we
7252 are the initiator to the remote router or whether we'll expect
7253 the other end to connect.
7255 * Moved registering of listener task to silc_server_init, hence
7256 the server starts listenning as soon as it is run, even if it
7257 does not have connections to other routers. Let's see how well
7260 * Changed default connection retry timeouts for more suitable in
7263 * Removed cipher and such arguments from silc_idlist_add_client
7264 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7265 Added new function silc_idlist_add_data to add the keys and stuff
7268 * Added SilcIDListData structure and added it to SilcClientEntry
7269 and SilcServerEntry as their first field in the structure. This
7270 way we can explicitly cast the ID entries to the SilcIDListData
7271 structure and get common data for the entries. In past, we had
7272 to first check what type of connection it is and then cast it to
7273 correct ID entry type. Now, we can directly cast the opaque
7274 pointer to the SilcIDListData (no matter what ID entry it actually
7275 is) and get the data needed.
7277 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7279 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7280 in some circumstances even if threre were timeout tasks, though not
7281 IO tasks, but tasks anyway. Now fixed.
7283 * Defined SilcServerConnection structure to hold connection specific
7284 stuff about directly connected servers and routers. The definition
7285 is currently in silcd/server_internal.h. I thought about having
7286 a bit more important role fro this struct but for now it is used
7287 only when connecting to other server (or router actually).
7289 * Added connecting retry support in server when connecting to
7290 router(s). The retry feature implement exponential backoff
7291 algorithm. Also, added SilcServerParams structure to hold default
7292 parameters for server. For now, it include these retry settings
7293 and are hard coded. After server is moded to be as Silc Server
7294 Library this structure will be more important.
7296 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7298 * Changed client librarys channel->clients table to SilcList and
7299 changed code accordingly.
7301 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7303 * Changed client's channel table to SilcList and changed code
7304 accordingly. Also changed SilcChannelClientEntry to include back-
7305 pointer to the channel so that client entry can use that structure
7306 as list as well and we have fast cross-reference to the channel.
7307 This change dramatically decreased the complexity of channel
7308 handling with client entry and vice versa (removed one extra
7309 loop when searching for channel entry from many functions).
7311 * Changed server->sim from table to SilcDList and changed code
7314 * NAMES command can now be used from user interface. It will show
7315 the user list on the channel, neatly.
7317 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7318 Code now saves realname of the user if it becomes available.
7320 * Renamed configure.in to configure.in.pre and made ./prepare
7321 script to automatically add correct version string to
7322 configure.in which it creates from configure.in.pre.
7324 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7326 * NAMES command reply now shows users mode with the nickname when
7329 * Moved silc_client_ch[u]mode[_char] functions from
7330 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7331 place sucks, they are utility functions and should be in some
7334 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7336 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7339 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7343 * Added TRQ (efficient deque and list library) into lib/trq. This is
7344 a very good list library that is currently used in the SILC. Defined
7345 SilcList API over the library because I didn't like the API very
7346 much. See lib/trq/silclist.h for the API and examples of how to
7347 use the API. Fixed various places in the code to use the new
7348 SilcList API. The SilcList is meant for lists that has a structure
7349 already defined as a list. It is not suitable to add just some
7350 context to the list (in TRQ, the context is the list actually).
7352 So, I defined SilcDList that can be used for the purpose where
7353 predefined list structure does not exit. This can be used as
7354 such list. Now some context just can be added to the SilcDList.
7355 Currently this list is not used in the SILC just yet, though there
7356 are a lot places where this can replace dynamically allocated
7357 tables and I will fix these places, later, to use SilcDList.
7358 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7359 and use TRQ internally).
7361 Also fixed some annoying warning messages that the original TRQ
7362 code generated. Also minor changes to TRQ's Makefile.in.
7364 * Added support for querying by Client ID to both WHOIS and
7365 IDENTIFY commands into server, as required by the protocol.
7367 * Removed method function pointers from SilcBuffer structure. They
7368 weren't used to anything and just increased the context size for
7369 no good reason. This change also made silc_buffer_alloc and
7370 silc_buffer_free functions inline functions.
7372 * Disabled command flooding detection support until it's fixed so
7373 that it accepts commands in but does not execute them more than once
7376 * Added silc_net_localhost(), to return local hostname, into
7377 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7378 that must be initialized before calling silc_client_init.
7380 * Added new function: silc_server_send_notify_on_channels to send
7381 notify messages to all channels client has joined. It is assured
7382 that the message is sent only once per client.
7384 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7385 lib/silcutil/silcutil.[ch] as silc_format function. The new
7386 function is generic and is used by server as well, not only by
7387 the logging routines.
7389 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7390 the provided version string was not acceptable. Added new function:
7391 silc_ske_check_version into lib/silcske/silcske.h. The function
7392 must be implemented by the application (client or server) and it
7393 does not reside in the SKE library. The function checks the version
7394 string remote end sent.
7396 * Added back pointers (to opaque context and to SilcSocketConnection)
7397 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7399 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7400 duplicate packet context structure.
7402 * Changed `notify' client operation to send same arguments as client
7403 receives from server except for ID's. ID's are mapped to correct
7404 ID entry and that is returned. Also, if channel entry is not sent
7405 by server but the notify is for channel the channel entry is sent
7406 to application (otherwise application doesn't know that it is for
7407 channel (library gets it from packet's Destination ID)).
7409 * Added silc_client_remove_from_channels into client library to
7410 remove a client from all channels it has joined to. Used when
7411 received SIGNOFF notify from server. Added also new function
7412 silc_client_replace_from_channels to replace old ID entry with
7413 new ID entry on all channels. Used when received NICK_CHANGE
7416 * Fixed ID Cache list handling in silc_idlist_get_client in
7417 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7418 to get (or query) client by ID.
7420 * Updated TODO list.
7422 * Added connection authentication status message defined by the
7423 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7424 support for these into the code in client and server side.
7426 * Added generic function silc_client_send_command to send any command
7427 with variable argument list. Application should use this function
7428 to send commands if the command functions provided by the library
7429 does not suite for the application's user interface needs.
7431 * Added new `failure' client operation. Application is notified about
7432 received failure packet if client is executing a protocol. In this
7433 case the protocol's execution has failed.
7435 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7436 is required by the protocol.
7438 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7439 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7442 * Added status flag to SilcSKE object to indicate realtime status
7443 of the SKE protocol.
7445 * Application receives now exactly same command reply arguments as
7446 the library receives from server. However, if ID is received the
7447 corresponding ID entry is returned to the application (eg. Client
7448 ID is mapped to correct SilcClientEntry entry and that is returned).
7449 Changed command_reply client operation due to this change.
7451 * Changed all ID's in commands and in command replys as ID Payloads.
7452 Change affected both client and server side codes.
7454 All ID's sent in SILC network (with execption of ID's in SILC
7455 Packet header) are sent in ID Payload to support variable length
7458 * Server now notifies nick changes and notifies all clients on
7459 the channels about the new nickname (about the new Client ID,
7462 * Implemented CMODE command to change channel modes. Supports all
7463 channel modes defined by the protocol specs except ban and invite
7464 lists. (Also, private channel key mode is supported but support for
7465 setting private channel key in client is missing, thus, this mode
7466 has no effect on client side (except that server requires that the
7467 client uses private channel key and normal channel traffic does not
7470 Also, invite mode works per se, but INVITE command does not work
7471 yet correctly, so you can set channel as invite only channel but
7472 inviting clients to the channel does not work (it is yet to be
7473 thought what's the best way to do it).
7475 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7476 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7477 Implemented CUMODE command to change user's mode on the channel.
7478 Supports all modes defined by the protocol specs.
7480 * Added NAMES command reply to return users modes on the channel.
7482 * Removed unnecessary and slow ciphers from lib/silccrypt.
7484 * Set SO_KEEPALIVE option to connection sockets by default.
7486 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7488 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7489 redefined the Notify Payload into protocol specs.
7491 * Added silc_id_payload_parse_id to get ID directly from raw
7494 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7496 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7497 accept searching by Client ID as well.
7499 * Added support for LEAVE and SIGNOFF notify types in client library.
7501 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7502 to parse ID Payload from raw data.
7504 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7506 * Added flags parameter into silc_ske_assemble_security_properties
7507 function in lib/silcske/silcske.[ch].
7509 * Changed notify client operation to fit better for notify messages
7510 sent by server. The notify payload received from server is now
7511 passed to the application (after parsing it to SilcNotifyPayload).
7512 It is application's responsibility to retrieve the arguments
7513 from the payload and show the message the way it wants. The message
7514 sent by server is implementation specific.
7516 * Changed public keys to comply with the protocol specification.
7517 Old public keys are not supported anymore and are not compatible.
7519 * Removed nickname from Channel Payload as the latest draft removed
7520 it. The client must resolve the nickname from the NAMES command
7521 reply received when it joined the channel.
7523 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7525 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7527 * Fixed some errors in protocol specification drafts.
7529 * Created lib/silccore/silcnotify.c to implement Notify Payload
7530 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7531 generic payloads described by protocol specifications. The file
7532 includes implementations for ID Payload and Argument Payload.
7534 * Changed Command Payload implementation to use the new Argument
7535 Payload. Changed command_xxxx_payload to command_payload_xxxx
7536 to comply with SILC coding conventions.
7538 * Added suppport for Argument Payload handling in Notify Payload
7539 implementation as protocol requires it. Added the new support
7540 into server and client lib as well.
7542 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7544 * Added support for multiple nicknames on same channel. [n] is
7545 added locally to the nickname if there are more than one same
7546 nicknames on the channel.
7548 * Server now sends all nicknames that matched WHOIS request.
7549 Client also shows the list received from server.
7551 * Added TOPIC command to client side. User can now set and show
7552 current topic on channel.
7554 * Added MOTD command to client and server. Also, server sends the
7555 motd when client connects to the server.
7557 * Changed version strings to comply ISO 8601.
7559 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7561 * Fixed protocol error handling in client library. It should now
7562 cope even if the SKE fails for some reason.
7564 * Made new protocol specification drafts for submitting to IETF.
7566 * Implemented TOPIC command to server in silcd/command.c.
7568 * Added two new notify types into lib/silccore/silcnotify.h:
7569 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7570 notify nickname change and topic setting/change on a channel.
7572 * API change of command_reply operation in client library. The
7573 application gets now the status type received from server as well.
7575 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7577 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7579 * Cras fixed and optimized the packet handling even further and
7580 it should work now. Minor change to the prototype of function
7581 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7583 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7585 * Added new function into lib/silcutil/silcschedule.[ch]:
7586 silc_schedule_with_fd to select() a specified fd. The function
7587 returns after timeout expires or data arrives or goes. The
7588 function is used by packet routines to wait that all data is
7589 received from network.
7591 * Fixed data reading from network in lib/silccore/silcpacket.c.
7592 The code now assures that all data is read from the fd and then
7593 continues packet processing. This was a bug fix since the code
7594 used to drop some data in some circumstances.
7596 * Added new function into lib/silcclient/client.[ch]:
7597 silc_client_start_key_exchange to start key exchange after
7598 connection has been established to server. The code internally
7599 now uses this funtion but its main purpose was to provide it
7600 for applications that perform their own connecting. After
7601 application has created a connection it merely calls this
7602 function to start the key exchange between client and server.
7603 The library takes care of everything else after that.
7605 Updated also lib/silcclient/README to explain the usage of
7608 * Do not send to application information that connection has
7609 been established. Application gets notified it by connect
7612 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7614 * Applied cras's patch to add silc_schedule_one function. The
7615 function runs scheduler once and returns.
7617 * Fixed the scheduler after cras messed it up. The timeout
7618 handling works now as it's supposed to work.
7620 * Added into lib/silccore/ silcnotify.h to include notify
7621 message types support. Changed silc_server_send_notify*
7622 functions, in server.[ch], to support those new notify types.
7623 Added the support for the notify types into client library,
7624 as well. Added new notify client operation into ops.h in
7627 * Changed silc_server_packet_send_to_channel to send normal
7628 packets instead of just channel message packets. The function
7629 is now used to send the notify packets to channels. It is not
7630 used to send channel message packets anymore, as server never
7633 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7634 va_arg()s as it seems to require it nowadays. I guess, if SILC
7635 is compiled with older va_arg() the new code should work anyway.
7637 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7639 * Splitted core library. Core library (lib/silccore) includes
7640 now only SILC protocol specific core (and common) components.
7641 Created new utility library (lib/silcutil) that includes more
7642 generic purpose stuff. The stuff for util library was taken
7643 from the old core library. This was minor and easy split.
7645 * Created SILC Client Library (lib/silcclient) that includes
7646 implementation of the SILC client without user interface. This
7647 was major move from silc/ directory. The code has been changed
7648 so that it is transparent towards the user interface. The
7649 silc/ directory includes now the same user interface as before
7650 and it uses the new client library. Read lib/silcclient/README.
7651 Basicly, the client library performs everything else related
7652 to SILC except user interface handling. Also, configuration
7653 files are considered to be part of user interface and library
7654 does not handle them.
7656 This change also changed a lot of structures, function naming etc.
7657 Most important change was that SilcClientWindow object was
7658 renamed to SilcClientConnection in the client library. Created
7659 also new file lib/silcclient/ops.h. Also added new files
7660 silc/local_command.[ch] and silc/client_ops.[ch].
7662 All these changes were made to make it easier for user interface
7663 designers to create what ever user interface for the SILC client
7666 It is also expected that the server will be moved to lib
7667 directory as well and SILC Server Library will be created;
7668 sometimes in the future.
7670 * Removed Local commands from lib/silccore/silccommand.h as
7671 they are application specific and new client library does not
7672 handle any of those anymore.
7674 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7675 old client implementation in silc/.
7677 * Added support for callback functions in SILC_LOG_* macros.
7678 Application can now set its own callbacks that will be called
7679 instead of using the default functions that will always print
7680 the debug messages to stderr (or stdout). Also, debugging can
7681 now be disabled by setting silc_debug to FALSE and re-enabled by
7682 setting it to TRUE. Note, that logging will still work even
7683 if debugging is disabled.
7685 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7686 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7687 silc_log_reset_debug_callbacks.
7689 * To enable debugging in silc client one must give now -d
7690 option on command line.
7692 * Changed silc_schedule_init to automatically allocate task queues
7693 if they are not allocated before calling it.
7695 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7697 * Added GMP 3.1 into math library.
7699 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7701 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7702 a channel in SILC network. The packet is used by servers and
7703 routers to notify other routers that user has left a channel.
7704 This little feature was missing until now. Added the feature
7705 to protocol specification as well.
7707 Added functions: silc_server_send_remove_channel_user and
7708 silc_server_remove_channel_user into server.[ch].
7710 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7711 lib/silccore/silcpacket.h. However, they are not implemented
7714 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7716 * Fixed joining to a channel and sending channel messages
7717 between server and router. The channel message sending should
7718 now work inside a cell.
7720 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7722 * Fixed the private message sending between server and router.
7723 The private message sending should now work inside a cell.
7725 * Added silc_server_replace_id into server.[ch] to replace
7726 existing ID in the SILC network.
7728 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7729 and silc_idlist_replace_server_id into idlist.[ch] in server.
7731 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7733 * Fixed the server to server connections. Server can again now
7734 connect to router. Router to router connections probably does
7737 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7739 * Added dynamic protocol registering support. Now protocols can
7740 registered and unregistered on the fly. Patch by cras.
7742 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7744 * Added lib/contrib directory to hold routines that some platforms
7745 don't have but are needed by SILC.
7747 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7748 into lin/contrib to provide getopt() and getopt_long() for
7749 those who don't have it.
7751 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7753 * Added AWAY command to client. When away message is set and
7754 client receives a private message packet the client automatically
7755 replies to the sender with the away message.
7757 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7758 bug seemed to be the cause of recent problems when compiling
7761 * Added version detection support to SKE protocol specification
7762 and added the new changes to the SKE implementation as well.
7763 There were other minor changes in the SKE protocol as well.
7765 Many changes in lib/silcske/silcske.[ch] and in
7766 lib/silcske/payload.[ch].
7768 * Added ^U functionality, clear input line. Patch from cras.
7770 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7772 * Mainly small bugfixes on core library. Fixed some debugging
7773 logging and buffer overflow in silclog.c.
7775 * Updated config.sub and config.guess on the distribution tree.
7777 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7779 * Added command lagging support in server. Client may execute
7780 commands now only once in two seconds.
7782 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7784 * Optimized packet reception. MAC computation and checking is now
7785 also more optimized. A lot previously duplicated code is now
7786 used as generic by both client and server.
7788 * Fixed key pair generation in clientutil.c
7790 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7792 * Added into lib/silccore/silcbufutil.[ch] new function;
7793 silc_buffer_realloc.
7795 * Moved generic packet sending/encryption functions to
7796 lib/silccore/silcpacket.[ch] from client and server. Some
7797 rewriting of the functions.
7799 * Moved all generic packet reception/decryption functions to
7800 lib/silccore/silcpacket.[ch] from client and server. The
7801 packet processing is now much cleaner in both client and server.
7802 These were major changes in both client and server.
7804 * Created many common functions in server to do packet sending.
7805 Previously code were duplicated a lot, this has been removed
7808 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7810 * Rewrote major parts of the ID cache system. Don't know
7811 whether it is better now or not but at least the API is more
7814 * Major rewrite on ID cache stuff on client because of the ID
7815 cache API changes. Added idlist.c to client.
7817 * Also major rewrite on ID cache stuff on server as well.
7818 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7819 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7820 in hand, instead they are all put into the ID cache system now.
7821 All server_idlist_* routines uses ID cache now instead of
7822 traversing its own lists (those lists does not exist anymore).
7823 SilcIDList though still exists. Also, SilcXXXEntry's are
7826 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7828 * Finally made the SKE implementation compliant to the protocol
7829 specification. All mp integers are now binary encoded as
7830 opposed being HEX encoded.
7832 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7835 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7836 functions: silc_[encode/decode]_pem. Also added function
7837 silc_encode_pem_file to PEM encode with newlines ('\n') for
7840 * SILC public keys are now encoded either PEM or binary. Same
7841 option is for private keys as well. By default private keys
7842 are binary encoded and public keys PEM encoded. Silly HEX
7843 encoding were removed.
7845 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7846 function to create fingerprints.
7848 * Fixed a bug in SHA1; does not change the original data anymore.
7850 * Partly implemented INFO command on client and server side.
7851 Fixed CLEAR command. Changes to SERVER command; show current
7852 server(s) when giving command without arguments. Added
7853 VERSION command to client.
7855 * Added check to server that unregistered connections cannot
7856 execute commands (unless it is specificly allowed).
7858 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7860 * Fixed screen refresh.
7862 * Fixed channel joining bug from client. On some circumstances
7863 client tried to join to a channel it had already joined.
7865 * Added public key verification process into client's protocol.c.
7866 The client now verifies the public key from user and saves
7867 it into ~./silc/serverkeys/ directory.
7869 Added into: clientutil.[ch]: silc_client_verify_server_key.
7871 * Changed SKE protocol's silc_ske_initiator_finish function
7872 to accept callback function that verifies the received public
7873 key. Removed old silc_ske_verify_public_key function.
7875 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7877 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7878 silc_pkcs_private_key[_data]_set.
7880 * Made the password and public authentication more cleaner in
7881 server's protocol.c.
7883 * Removed historic and obsolete protocol `channel_auth' from
7884 both client and server.
7886 * Removed wrong way of sending command status messages from
7887 server to client in server's command.c. The old way violated
7888 protocol specification.
7890 Changes to silccore/silccommand.[ch]: removed
7891 silc_command_encode_status_payload -> not needed anymore,
7892 changed silc_command_encode_payload_va to accept extra
7893 argument on variable argument list. The argument type must
7894 now be provided to the function. Also, added new function:
7895 silc_command_encode_reply_payload_va which is same as
7896 normal command_encode_payload_va except command status type
7897 is provided as extra argument.
7899 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7901 * Added ~./silc directory handling. The directory includes the
7902 public and private keys for the client.
7904 Added silc_client_check_silc_dir, silc_client_create_identifier
7905 and silc_client_load_keys.
7907 * Implemented SILC protocol compliant public key. Added public
7908 and private key saving to and loading from files.
7910 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7911 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7912 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7913 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7914 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7916 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7917 silc_pkcs_load_[public/private]_key.
7919 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7921 * Added silc_server_get_route (route.[ch]) to get connection
7922 data for the fastest route for given ID.
7924 * Implemented INVITE command on client and server. The command
7925 were re-defined in the SILC Protocol Specification and the
7926 implementation now complies with the specification.
7928 * Implemented PING command on client and server.
7930 * Implemented NAMES command on client and server. The server side
7931 supports currently only normal server not router server yet.
7932 Some changes to NAMES definition in SILC protocol specification.
7934 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7936 * Implemented LEAVE command on client and server.
7938 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7939 again. This change was made to the protocol as well. Server
7940 should not violate the protocol specification anymore.
7942 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7944 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7945 was tested. SOCKS4 was not but should work anyway.
