3 * Changed the UMODE's mode mask argument to be optional. If
4 not provided then the command merely returns the current mode
5 mask to the client. Updated protocol specs and the server.
6 Affected file is silcd/command.c.
8 * Added SILC session detachment/resuming support. It is possible
9 to detach by closing the network connection and then re-connect
10 and resume to the old client session. Added DETACHED user
11 mode that server will set for detached client. Added new
12 packet RESUME_CLIENT which is used to perform the resuming
13 process. Added DETACH command. Updated the protocol specs,
14 core library, client and server. Protocol TODO #22. Very
15 many affected files around the tree.
17 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
19 * Changed the CMODE's mode mask argument to be optional. If
20 not provided then the command merely returns the current mode
21 mask to the client. Updated protocol specs and the server.
22 Affected file is silcd/command.c.
24 * Changed the Killer's Client ID in KILLED notify to be just
25 any ID payload since router server is allowed to kill as well.
26 Updated protocol specs, client libary and server. Affected
27 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
28 and irssi/src/silc/core/client_ops.c.
30 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
32 * Added new user modes ANONYMOUS for special anonymous servers
33 that may set the mode for client, and BLOCK_PRIVMSG which
34 client may set to block incoming private messages unless the
35 Private Message Key flag is set (using private keys to protect
36 private messages). Updated protocol specs and code in client
37 and server and core library. Protocol TODO #23. Affected
38 files are lib/silccore/silcmode.h, silcd/server.[ch],

40 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
42 * Added new channel user mode BLOCK_MESSAGES which the client
43 may set to itself to tell server not send channel messages.
44 Other packets such as channel key packets are still sent.
45 Protocol TODO #23. Updated the protocol specs, client and
46 server. Affected files are lib/silccore/silcmode.h,
47 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,

51 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
53 * Redefined the Status Payload to include now two 8 bit fields,
54 instead of one 16 bit field. This now makes it possible to
55 send list of errors. Updated the protocol specs and the code
56 in core library, client library and server. Protocol TODO #1.
57 Affected files are lib/silccore/silccommand.[ch],
58 lib/silcclient/command_reply.[ch], silcd/command.c,

61 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
63 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
64 must be handled by the application and should tell the application
65 that an error message was already printed, and it should print the
66 config coords (line, filename, ...). Affected files are
67 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
69 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
70 server config parsing code more readable.
72 Fixed a bug in the fetch_logging() config callback.

88 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
90 * Added STATS command to the protocol after all, to return
91 various statistical information about the network. It can
92 be used by clients to retrieve statistical information, and
93 servers may use it to to fetch cell and network wide
94 statistics from router. Updated the protocol specs and
95 implemented it to the server. Protocol TODO #16.
96 Affected files are lib/silccore/silccommand, silcd/command.[ch],
97 silcd/command_reply.[ch].
99 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
101 * The LIST command reply in client libary now adds new channel
102 entry if the returned channel doesn't exist yet in cache,
103 and returns the channel entry to the application in the
104 command_reply client operation. Affected file is
105 lib/silcclient/command_reply.c.
107 * Changed the channel message payload's MAC generation to
108 include the IV in the MAC as well. This way all relevant
109 parts of the channel message payload are authenticated also
110 with the channel message MAC (and not only by packet MAC).
111 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
112 Affected file is lib/silccore/silcchannel.c.
114 * Fixed the SKE to save the remote version, since the
115 silc_ske_parse_version mistakenly checked wrong version,
116 after it replaced the start payload. Affected files are
117 lib/silcske/silcske.[ch].
119 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

126 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
127 files are lib/silcutil/silcstrutil.[ch].
129 * Defined that the security property fields in SKE SHOULD be
130 UTF-8 encoded, defined that version string MUST be US-ASCII
131 encoded, defined that passphrases sent in connection
132 authentication protocol MUST be UTF-8 encoded. Implemented
133 these to the client and server. Defined also that other
134 passphrases sent in the protocol MUST be UTF-8 encoded.
135 Affected files are lib/silcske/silcske.c,
136 lib/silcclient/protocol.c, silcd/protocol.c,
137 silcd/serverconfig.c, and lib/silccore/silcauth.c.
139 * Changed the silc_client_close_connection interface to not
140 need the SilcSocketConnection which should not be visible
141 to application. Affected files are lib/silcclient/client.c
142 and lib/silcclient/silcclient.h.
144 * Rewrote the text for Private Message Key Payload in the
145 protocol specification. Protocol TODO #11.
147 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
149 * Upgraded the protocol version to 1.1, updated protocol specs
152 * Added the nickname as new argument to NICK_CHANGE notify and

160 Protocol TODO #13. Affected files are silcd/command.c,
161 silcd/packet_receive.c, packet_send.[ch],
162 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
163 The killer's client entry is now returned to application in
164 the `notify' client operation.
166 * Fixed the Max Argument fields that had too large value set
167 in the protocol specs. Protocol TODO #14.
169 * Added the LEAVE command reply to return the ID of parted
170 channel. Updated protocol specs and implemented it to the
171 client and server. Protocol TODO #15. Affected files are
172 silcd/command.c, lib/silcclient/command_reply.c. The channel
173 entry is now returned to application in the `command_reply'
176 * Rewrote the version SKE version checking in client libary
177 and in server to use the silc_parse_version_string. Affected
178 files are lib/silcclient/protocol.c, silcd/protocol.c.
180 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
181 commands that was missing it, and updated protocol specs and
182 the server implementation. Protocol TODO #10. The affected
183 file is silcd/command.c.
185 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
186 generic reply to a generic request (REQUEST flag), and
187 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
188 way. A draft-riikonen-silc-flags-payloads-00.txt is written
189 to define the payload for DATA flag. Added the flags to
190 the implementation. Protocol TODO #9. Affected file is
191 lib/silccore/silcchannel.h.
193 Changed the client library to return the message length
194 to application as well in the channel_message and private_message
195 client operations. Affected files are
196 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
197 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
198 and lib/silcclient/client_ops_example.c.
200 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
201 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
202 the channel. Updated protocol specs and impelemented this
203 to client and server. Protocol TODO #6. Affected files are
204 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

207 Added new options m and M to CMODE command in Irssi SILC
208 client to set these modes.
210 * Deprecated all administrative commands from SILC protocol
211 since they are highly implementation specific commands.
212 Updated protocol specs. Moved the old commands in
213 implementations to private range of command types. Affected
214 files are silcd/command.c, lib/silcclient/command.c and
215 lib/silcclient/command_reply.c. Protocol TODO #8.
217 * Fixed a bug in server where sending unknown command crashes
218 the server. Affected file silcd/command.c.
220 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
222 * Added SILC_PROTOCOLVERSION macro to check protocol version
223 of a socket connection. The affected file is
224 lib/silcutil/silcsockconn.h.

233 Affected file silcd/protocol.c.
235 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
237 * Some client implementations quit network by doing first LEAVE
238 and then immediately SIGNOFF (like Bombyx). We now do check
239 after a short time after LEAVE notify and check whether the
240 client is still valid after LEAVE, and if not we remove it from
241 cache. Affected file is lib/silcclient/client_notify.c.
243 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
245 * Merged version 1.1.4 of zlib. Even if it not currently in use,
246 it's good not to have security holes here.
248 * Fixed a negative refcount situtuation for the config context.
249 Affected file is silcd/serverconfig.c.
251 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
253 * ROBOdoc documented lib/silcutil/silcutil.h.
255 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>

258 totally saved 16 bytes of memory per context after optimization.
259 Affected files are lib/silccore/silcpacket.[ch].
261 * Made strict checks for valid SILC IDs. Affected file is
262 lib/silccore/silcid.c.

269 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
271 * Changed the silc_get_username and silc_get_real_name to
272 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
274 * Fixed the Irssi SILC Client to use the silc_get_username and
275 silc_get_real_name insted of glib routines since the glib
276 routines only corrupt stack. Fixes the Irssi SILC to work in
277 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
279 * Fixed the Irssi to not use g_get_home_dir since it crashes
280 or returns garbage on cygwin and corrupts stack. Added function
281 get_home_dir to Irssi routines. Affected files are
282 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
284 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
286 * Made some structure optimizations. SFTP memory FS MemFSEntry
287 entry structure. Optimized SilcTask structure. Optimized
288 SilcPacketContext structure.
290 Affected files lib/silcsftp/sftp_fs_memory.c,
291 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
293 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
295 * And yet again reverted back the config thing since Johnny
296 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
299 * Fixed memory leaks from config object. Affected files are
300 silcd/serverconfig.[ch].
302 * Added support for adding new connections to the server in rehash.
303 After rehash they take effect.
305 Added support for changing the maximum allowed connections in
306 rehash. The number can grow but going smaller is not supported.
308 Added function silc_server_num_sockets_by_remote to the
309 silcd/server_util.[ch].
311 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
313 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
315 * Added preliminary checking during config parsing for a valid
316 public/private key and removed further checks in the code.
317 Affected files are silcd/serverconfig.[ch], server.c.
319 * Moved functions silc_server_drop() and silc_server_daemonise()
320 from server.c to silcd.c since they are stricly related to
321 the application activity.
323 * Reverted a small part of the automatic ref/unref since
324 it caused a double unref in some situations. Affected
325 files are silcd/silcd.[ch], server.c, serverconfig.c.
327 * Added some .cvsignore files in the lib directory.
329 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
331 * Fixed silc_net_gethostbyaddr to correctly resolve by
332 address. Affected file lib/silcutil/silcnet.c.
334 * Fixed the notify relaying to client. The HMAC to be used
335 with relayed packets ws wrong and caused decryption failure
336 at the client end. Affected file is silcd/packet_receive.c.
338 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
340 * Created new branch silc_protocol_1_0_branch.
342 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
344 * Changed the silc_server_config_* routines to be SilcServer
345 independent. They are now officially application specific code
346 and not part of generic server implementation. Affected files
347 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
349 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
351 * Added automatic referencing of config context in the
352 silc_server_config_alloc, and automatic unreferencing in the
353 silc_server_config_destroy. Affected files are
354 silcd/serverconfig.[ch], silcd/silcd.c.
356 * Fixed the silc_log_quick handling in the logging routines.
357 It didn't log quickly when it was TRUE. Affected file is
358 lib/silcutil/silclog.c. Also the flush delay was set even
359 if it was 0 in config file. Affected file is
360 silcd/serverconfig.c.
362 * Added support for changing key pair of the server in rehash.
363 Affected file silcd/server.c.
365 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
367 * Fixed the TOPIC_SET notify to not cras. It changed the topic
368 too early, before getting the channel entry. Affected file
369 is silcd/packet_receive.c.
371 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
373 * Added functions silc_server_config_[ref/unref], these are used
374 to prevent that the config object is destroyed.
376 No longer directly affect global variables silc_log_quick and
377 silc_log_delay, they are first cached inside the config object
378 and then applied with silc_server_config_setlogfiles().
380 silc_server_config_set_defaults() is now internal to
381 serverconfig.c, there are no reasons to show this internal stuff
384 Affected files are silcd/serverconfig.[ch].
386 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
387 fprintf's to stderr, since some code may be executed again after
388 the server went into the background. Affected files are
391 * Added rehash support. Added function silc_server_rehash() that
392 will perform all the basic tasks of the rehashing procedure.
394 * Added command line option `-x, --hexdump'. This will enable the
395 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
396 The option `--hexdump' implies `--debug'.
398 * Fixed a bad bug in the logging APIs (silcutil library) where
399 the application would crash after calling silc_log_reset_all().
401 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
403 * Fixed the KICKED notify handling in client library to
404 correctly remove the channel and all entries from the
405 channel when I was kicked. This bug crashed the client.
407 Fixed yet another but in KICKED notify handling to remove
408 the kicked client correctly from the channel.
410 Affected file is lib/silcclient/client_notify.c.
412 * Fixed a minor bug in looking up correct client entry
413 in KICKED notify in server. Affected file is
414 silcd/packet_receive.c.
416 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
417 sources correctly to distribution. Fixes --with-gmp option.
419 * Removed the manual rehashing from ID Cache, and changed it
420 to use the SILC Hash Table's auto rehash feature. Affected
421 file is lib/silccore/silcidcache.c.
423 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
425 * Fixed a bug in the silc_client_nickname_format function that
426 handles the multiple same nickname formatting. Two clients
427 with same nickname caused problems after the first one left
428 and rejoined. It didn't format the nickname correctly.
429 Affected file is lib/silcclient/idlist.c.
431 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
433 * Don't change the topic if olod topic is same as new one.
434 Affected file is silcd/packet_receive.c.

439 generator. All types across all HTML files are now cross-
440 referenced. Affected files util/robodoc/generator.c and
441 scripts/silcdoc/silcdoc.
443 * Added file lib/silcutil/silctypes.h to include all the
444 arithmetic type definitions and some macros. Removed
445 includes/bitmove.h and moved macros to silctypes.h.
447 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
449 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

476 allowed by the client. Affected file silcd/packet_receive.c.
478 * Created function silc_get_input which can be used to get input
479 (echo on or off) from user on command line. Affected files are
480 lib/silcutil/silcutil.[ch].
482 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
484 * Optimized silc_server_packet_relay_to_channel function.
485 Added new function silc_channel_message_payload_encrypt which
486 can be called directly if channel message payload needs to
487 be encrypted and is already encoded (no need to call _encode
488 function). Packet relaying is now done by router without any
489 extra memory allocations. Affected files are
490 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and

511 by the client. Affected files are silcd/server_util.[ch],
512 silcd/packet_receive.c and silcd/command.c.
514 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
516 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
517 ID length. It ignored that ID can be IPv6 based as well.
518 Affected file lib/silccore/silcpacket.h.
520 * Fixed the silc_id_id2str and silc_id_str2id to take the
521 IPv6 address offset's into consideration. Affecte file is
522 lib/silccore/silcid.c.
524 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
526 * Fixed the internal Unix scheduler functions to check for
527 NULL context they may receive. The affected file is
528 lib/silcutil/unix/silcunixschedule.c.
530 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
532 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
533 can specify different directory with --home command line
534 parameter. Affected files irssi/src/silc/core/client_ops.c,
537 * SILC-specific commands aren't now executed if the active server
538 isn't of SILC-type, so there won't be problems with having
539 IRC and SILC protocol support in same client. Affected files
540 irssi/src/silc/core/silc-channels.c, silc-servers.c,
543 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
545 * Improved the signal support in SILC Schedule. Added new
546 function silc_schedule_signal_call which is used by application
547 to mark a signal to be called. It is now safe to perform
548 any kind of tasks in signal callbacks since it is guaranteed
549 that the application specified signal callback is called
550 after the signal is over. Affected files are
551 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
553 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
555 * Added `name' field to SilcChannelPrivateKey to represent
556 application given name for the key. Moved also the context from
557 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
558 Added the `name' argument also to the function
559 silc_client_add_channel_private_key.
561 Added function silc_client_current_channel_private_key to set the
562 current channel private key in use.
564 Added "change" command to KEY command which can be used to change
565 the current channel private key. Bound the command also to
568 Also affected files lib/silcclient/client_channel.c,
569 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
571 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
573 * Added silc_rng_get_byte_fast function in to the
574 lib/silccrypt/silcrng.[ch].
576 * Changed the interface of silc_packet_assemble and the
577 silc_packet_send_prepare. If silc_packet_assmble is now
578 called the application does not call silc_packet_send_prepare
579 because the library will call it automatically. These
580 interfaces now also return a reference to the outgoing buffer
581 which includes the assembled packet, which the application can
582 use to encrypt the packet.
584 Affected files are lib/silccore/silcpacket.[ch],
585 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
586 silcd/packet_send.c, server_backup.c and packet_receive.c.
588 * Fixed a packet sending bug on very high load, where outgoing
589 packet queue wasn't handled correctly and packets got corrupted.
590 Affected files are lib/silcutil/*/silc*sockconn.c,
591 lib/silcclient/client.c and silcd/server.c.
593 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
595 * Added macro SILC_PACKET_DATALEN which can be used during
596 packet assembling to check whether the data to be added to
597 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
598 len is truncated until it fits it.
600 Added checks for maximum length of channel message payload and
601 private message payload also.
603 Added checks for maximum packet length in server and in
606 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
607 lib/silcclient/client.c, lib/silccore/silcchannel.c and
608 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
609 lib/silcclient/client_prvmsg.c.
611 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
613 * Added silc_server_packet_queue_purge call to the
614 silc_server_disconnect_remote to assure that all data in the
615 queue before disconnecting is sent to the network. Affected
618 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
620 * Added the deleting of server's own ID cache entry to the
621 silc_server_free function. Free also everything else that
622 has been allocated in silc_server_init. The affected file
625 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
627 * Added functions silc_parse_version_string, silc_version_to_num,
628 and silc_ske_parse_version to parse SILC protocol style version
629 strings. Affected files lib/silcutil/silcutil.[ch] and
630 lib/silcske/silcske.[ch].
632 * Added new configuration params: version_protocol, version_software
633 and version_software_vendor to specify what version the remote
634 host must at least be to be able to connect to server. The vendor
635 string can be regex matched too. Added new function
636 silc_server_connection_allowed to check maximum number of allowed
637 connections, and allowed versions for incoming connections.
638 Affected files are silcd/server.c, server_util.[ch] and
641 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
643 * Added preliminary support for signals in scheduler. The
644 signals we care about are now blocked always when the scheduler
645 is locked. This way we can synchronise the use of signal with
646 scheduler. It is guaranteed that when signal occurs the scheduler
647 is not locked, and thus new tasks can be safely added to the
650 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
651 to silc_schedule_internal_init and silc_schedule_internal_uninit.
652 Added new platform specific routines
653 silc_schedule_internal_signals_[un]block and
654 silc_schedule_internal_signal_[un]register.
656 Added new functions to SILC Schedule API:
657 silc_schedule_signal_[un]register. Each signal that application
658 is going to use should be registered to the scheduler.
660 Affected files are lib/silcutil/silcschedule.[ch],
661 lib/silcutil/*/silc*schedule.c.
663 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
665 * Check for unauthenticated client and server in the
666 silc_server_new_client and silc_server_new_server functions.
667 Affected file silcd/packet_receive.c.
669 * Added function silc_string_is_ascii to check whether given
670 string is 7-bit ASCII string. Affected files are
671 lib/silcutil/silcutil.[ch].
673 * Added function silc_id_is_valid_server_id into the
674 silcd/serverid.c and added checking for valid Server ID's in
675 silc_server_new_server. The Server ID must always be based
676 on the server's public IP address.
678 * Added logging of DISCONNECT packet message in the server.
679 Affected file silcd/server.c.
681 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
683 * Changed all library interfaces that use Global RNG to also
684 accept SilcRng as argument. Affected files are
685 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
686 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
687 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
688 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
691 * Added function silc_pkcs_generate_key to the
692 lib/silccrypt/silcpkcs.[ch] for applications so that they
693 don't need to do pkcs->pkcs->init calls anymore.
695 * Remove SilcSocketConnection from the SFTP API since it really
696 wasn't needed there. The application has the information
697 saved in its contexts anyway and the SFTP layer doesn't need
698 know about it. Affected files lib/silcsft/silcsftp.h and
699 lib/silcsftp/sftp_[server/client].c.
701 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
702 The SilcSimContext is not SilcSim.
704 * Fixed possible buffer overflows in silc_id_render in the
705 lib/silcutil/silcutil.c.
707 * On EPOC the global crypto module lists are not used at all
708 in the crypto library. Added support for using the constant
709 algorithm list on EPOC. Affected files are
710 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
713 * Fixed the handling of third parameter of KICKED notify, since
714 it was mistakenly updated to SILC Protocol 1.0 even though it
715 is to be included in 1.1. Since it is not in 1.0 it is not
716 mandatory, and this fix now handles it only if it is provided,
717 and it is not error if it is not provided. Affected file
718 lib/silcclient/client_notify.c.
720 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
722 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
723 client. Affected file irssi/src/silc/core/client_ops.c.
725 * Merged with Irssi 0.8.4 from irssi.org CVS.
727 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
729 * Check for valid socket connection in client entries before
730 sending any messages. Fixes a crash, but doesn't fix some
731 other underlaying bug that is lurking there. Affected
732 file silcd/packet_send.c.
734 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
736 * $usermode, $cumode and $cumode_space expandos shouldn't do
737 anything with non-SILC server records. Affected file
738 irssi/src/silc/core/silc-expandos.c
740 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
742 * Fixed the silc_net_check_[host/local]_by_sock to support
743 IPv6 bound sockets as well. Now they can return IPv6 addresses
744 as well. Affected file lib/silcutil/silcnet.c.
746 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
747 Affected lib/silcutil/unix/silcunixnet.c.
749 * Fixed ID rendering (at least on some platforms, not NetBSD)
750 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
752 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
754 * Added silc_hash_public_key and silc_hash_public_key_compare
755 functions to be used with SilcHashTable. They can be used to
756 hash public keys and compare public keys in hash table. Affected
757 file lib/silcutil/silcutil.[ch].
759 * Added support for specifying multiple public keys for Client
760 connection section in server configuration file. This makes it
761 possible to accept multiple public keys from same host, or to
762 make a section that accepts any incoming host, and have the
763 accepted public keys listed in the section.
765 Added functions silc_sever_[find/get]_public_key, added the
766 support for this actually to all connection sections but only
767 the Client section is currently allowed to specify multiple
770 Affected files are silcd/server.c, server_internal.h,
771 command.c, protocol.c, server_util.[ch], packet_receive.c.
773 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
775 * Merged Irssi 0.8.2 from irssi.org CVS.
777 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
779 * If silc_debug is TRUE, also output standard logging messages
780 to stderr with the debug output.
782 Made silc_log_reset_all() flushing all channels before returning.
783 Also fixed some documentation typos.
785 Affected files are lib/silcutil/silclog.[ch].
787 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
789 * Fixed the server to check correctly the amount of connections
790 from single host, by checking also the type of the connection.
791 Fixed also the comparison of number of connections and number
792 of allowed connections. Affected files are silcd/server.c,
795 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
797 * Fixed the USERS command reply to save the user's mode on the
798 channel as well. Fixed JOIN command reply to check whether a
799 client is on channel already and not join it twice. Affected
800 file lib/silcclient/command_reply.c.
802 * Added new file silc-expandos.c into irssi/silc/core/ to return
803 various stuff for various signal for the statusbar etc. updating.
804 Now Irssi SILC client prints channel user modes etc. on the
807 * The user mode (like server/router operator changes) is now shown
808 on the Irssi SILC client's statusbar. The affected files are
809 irssi/src/silc/core/client_ops.c, silc-expandos.c.
811 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
813 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
814 to SILC_SCHEDULE_[UN]LOCK macros.
816 * Added more error printing to logs in server code. Affected
817 files silcd/server.c and silcd/protocol.c.
819 * Fixed -S option parsing in Irssi SILC Client. Affected file
820 irssi/src/silc/core/silc-core.c.
822 * Added silc_buffer_alloc_size function. Affected file is
823 lib/silcutil/silcbuffer.h.
825 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
827 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
828 constants. Affected files in
829 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
832 * Changed the internal SFTP Memory FS table to const. Affected
833 file lib/silcsftp/sftp_fs_memory.c.
835 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
837 * Fixed the buffer formatting and unformatting routines to
838 check the size of 64 bits types with sizeof(). Affected
839 file is lib/silcutil/silcbuffmt.c.
841 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
843 * Removed 0.6.x backwards support.
845 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
847 * Changed all integer type names:
848 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
849 to avoid collisions with other libraries using same type names
852 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
854 * Added `prefer_ipv6' argument to the functions
855 silc_net_gethostbyname[_async]. If it is TRUE it will return
856 IPv6 address over IPv4. If FALSE IPv4 address is returned
857 even if IPv6 address was found. Affected files
858 lib/silcutil/silcnet.[ch].
860 * Added support silc_net_create_connection[_async] to fallback
861 to IPv4 address if IPv6 address could not be used (like if
862 it doesn't work on a specific system). Affected file in
863 lib/silcutil/unix/silcunixnet.c.
865 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
867 * Added silc_schedule_reinit function to do the enlarging
868 of the max tasks handling capabilities of the scheduler.
869 Affected files lib/silcutil/silcschedule.[ch].
871 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
873 * Added automatic extern "C" { ... } for C++ compilers so the
874 application does not need to define them. Affected file
875 includes/silcincludes.h.
877 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
878 old name went against naming convention. Applications now
879 include "silcclient.h" instead of "clientlibincludes.h".
880 Removed includes/clientlibincludes.h, it is redundant now.
882 * Renamed includes/version.h to silcversion.h.
884 * Added really preliminary support for OS/2 into the util
885 library. Only thread & mutex API is implemented, others
886 are still to be implemented. Created the lib/silcutil/os2/
887 directory. Created also file includes/silcos2.h.
889 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
891 * Added preliminary BeOS support into the util library.
892 Created lib/silcutil/beos/, and implemented all the needed
893 functions to support SILC on BeOS. Created also file
896 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
898 * Added proper initializations to silc's irssi code, so it's
899 now possible to load it as module. Affected files
900 irssi/src/silc/core/silc-core.c,
901 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
903 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
905 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
908 * Fixed the silcdoc document generator to correct generate
909 docs from all kinds of filenames. Affected files are
910 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
912 * ROBOdoc documented lib/silcutil/silcmemory.h.
913 Added also new function silc_memdup.
915 * Removed lib/silcutil/silcbufutil.h and moved those routines
916 to the lib/silcutil/silcbuffer.h.
918 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
920 * Added `user_count' to the SilcChannelEntry which now tells the
921 number of users on the channel. The user count is now saved
922 in normal server of global channels as well. Affected files
923 silcd/server.c, idlist.h, packet_receive.c and command.c.
925 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
926 include file utility functions.
928 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
929 instead of calling directly OS routines.
931 * Fixed NICK change printing in Irssi SILC Client. Fixed
932 KICKED notify printing in Irssi SILC Client. Affected file
933 irssi/src/silc/core/client_ops.c.
935 * Fixed a NICK change bug in client library, to not recreate the
936 client_entry->channels hash table everytime nick is changed.
937 Affected file lib/silcclient/client.c.
939 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
941 * ROBOdoc documented the lib/silcske/silcske.h, and improved
942 the SKE interface a bit.
944 * Fixed padding problem in PKCS#1. The padding was not actually
945 random since the random number generator was used incorrectly.
946 This security bug affects only when encrypting with PKCS#1, and
947 it is not currently used at all in SILC. SILC only use signing
948 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
950 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
952 * Rewrote the notify handling in Irssi SILC client to not call
953 the events as signals. Fixes problems with Perl support.
954 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
956 * Send the auto-nicking NICK command in client library with
957 little timeout after connecting. The affected file is
958 lib/silcclient/client.c.
960 * Added following new config file settings:
961 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
962 key_exchange_timeout, conn_auth_timeout, connections_max,
965 Implemented all the new config settings handling in the server.
967 Optimized the use of SKE Mutual flag usage. Use it only
968 if connection authentication protocol is not based in public
971 Renamed all SilcServerConfigSection* to SilcServerConfig*
972 to have a bit shorter names.
974 Affected files silcd/serverconfig.[ch], server.[ch], and
977 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
979 * Cleaned up the listening sockets code, preparing for the rehash
980 support. Affected file is silcd/server.c.
982 * Fixed some output messages. Affected files are silcd/silcd.c,
985 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
987 * Create lib/doc/silcrng_intro.html document as introduction
988 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
990 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
992 * Fixes to the silcd config template. Affected file is
993 doc/example_silcd.conf.in.
995 * Removed type casts from silc_calloc(), conforming to the
996 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
998 * Removed param_name member from client, server, and router
999 section structs, now identifying the param directly.
1001 Added CONFIG_FREE_AUTH macro in config file parsing.
1003 Affected files are silcd/serverconfig.[ch].
1005 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1007 * Fixed command line parameter handling. All SILC initialization
1008 is now done in silc_core_init() which also fixes autoconnecting
1011 Affected files irssi/src/silc/core/silc-core.c,
1012 irssi/src/fe-text/silc.c.
1014 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1016 * Added new configuration options and blocks:
1017 keepalive_secs, reconnect_count, reconnect_interval,
1018 reconnect_interval_max, reconnect_keep_trying and
1019 require_reverser_lookup. Added ConnectionParam block, and
1020 implemented the connection parameters when connecting as
1021 initiator and when accepting connections as responder.
1023 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1024 whether given configuration value has been given already.
1026 Affected files silcd/serverconfig.[c], server.[c].
1028 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1029 algorithm parts and created new file silcalgs.conf, that
1030 is now included from the example_silcd.conf.in.
1032 * Optimized the silc_server_connect_to_router_second to take
1033 the connection configuration object from the SilcServerConnection
1034 object instead of finding it during the connecting phase.
1035 Added the configuration object to SilcServerConnection struct.
1036 Affected files silcd/server_internal.h, server.c.
1038 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1040 * Add the client on channel after it was resolved at the
1041 channel message receiving, and it was not already on the
1042 channel. Affected file lib/silcclient/client_channel.c.
1044 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1046 * Fixed the public key authentication to allocate always the
1047 destination signature buffer instead of using static buffer.
1048 Affected file silcd/protocol.c.
1050 Wed Feb 13 20:51:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1052 * Unified the serverconfig.[ch]'s helper function interface.
1053 Affected file silcd/serverconfig.[ch].
1055 * Removed doc/example_silc.conf.in since it is redundant.
1056 The make install will now install irssi/silc.conf file.
1058 * Added new Passphrase and Publickey authentication methods to
1059 config file, allowing both public key and passphrase based
1060 authentication to be set at the same time.
1062 Added `prefer_passphrase_auth' setting in config file which
1063 can be used to set to prefer passwd auth if both passwd and
1064 public key is set. If not set, public key is preferred.
1065 This has effect only when being initiator (responder will try
1068 Added support for authentication with passphrase and public key
1069 at the same time. The passphrase is tried first always since
1070 it is faster to check.
1072 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1074 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1076 * Merged the new SILC Config library, with the server parsing
1077 support. Read the header file silcconfig.h or the toolkit
1078 documentation for the news. Affected files are
1079 doc/example_silcd.conf.in lib/silcutil/silcconfig.[ch]
1080 silcd/command.c silcd/packet_receive.c silcd/packet_send.c
1081 silcd/protocol.c silcd/server.c silcd/server_backup.c
1082 silcd/serverconfig.[ch] silcd/silcd.c.
1084 * Fixed some silclog documentation. Affected file is
1085 lib/silcutil/silclog.h.
1087 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1089 * The silc_cipher_register, silc_hash_register and
1090 silc_hmac_register now checks if the object to be registered
1091 is registered already. Affected files are
1092 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
1094 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1096 * Merged new irssi from irssi.org's CVS, the version 0.7.99.

1100 * Allow zero length channel messages inside the Channel Message
1101 Payload. Affected file lib/silccore/silcchannel.c.
1103 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1104 as header filenames.
1106 * Removed lib/silcclient/README and created HTML file
1107 lib/silcclient/silcclient_using.html, which is now included
1108 as part of Toolkit documentation.
1110 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1112 * Fixed CUMODE_CHANGE notify handling to change the mode of
1113 correct client. Affected file lib/silcclient/client_notify.c.
1115 * Make silc_rng_alloc fail if it cannot allocate the sha1
1116 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1118 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1120 * Fixed the file transfer's key agreement payload to include
1121 zero port also if the hostname is NULL because it could not
1124 Call file transfer monitor callback now also if error occurs
1125 during key agreement protocol.
1127 Changed the silc_client_file_send interface to return the
1128 SilcClientFileError instead of session id. The session ID
1129 is returned into pointer provided as argument.
1131 Check that the file exists locally before sending the
1132 file transfer request at all.
1134 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1136 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1137 error than can occur while key agreement protocol. Affected
1138 file lib/silcclient/silcapi.h.
1140 * Fixed the event_mode CMODE handler to not crash when mode
1141 is changed and +k mode is set in the channel. Affected file
1142 irssi/src/silc/core/silc-channels.c.
1144 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1145 SILC_LOG_WARNING to give out Warning and not Error. Affected
1146 file lib/silcutil/silclog.c.
1148 * Fixed the channel message payload decryption in the function
1149 silc_channel_message_payload_decrypt to not modify the original
1150 buffer before it is verified that the message decrypted
1151 correctly. Otherwise, next time it is called with correct
1152 channel key it won't encrypt since the payload is corrupted.
1153 Affected file lib/silccore/silcchannel.c.
1155 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1157 * Do not constantly resize the window. A fix patch by cras.
1158 Affected file irssi/src/fe-text/screen.c.
1160 Sat Feb 2 16:54:18 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1162 * Applied IPv6 fix patch from Jun-ichiro itojun Hagino.
1163 Affected file lib/silcutil/silcnet.c.
1165 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1167 * Fixed a bug in hash table internal routine for traversing
1168 the table with foreach callback. The current entry may
1169 become invalid in the callback but it was referenced after
1170 the callback returned.
1172 Do not allow auto rehashing of hash table during the
1173 silc_hash_table_foreach operation, for same reasons as it is
1174 not allowed for SilcHashTableList. Affected files are
1175 lib/silcutil/silchashtable.[ch].
1177 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1179 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1180 Win32 DLL. extern's in header files are now declared with
1183 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1185 * Fixed private message handling. It used some old code that
1186 caused the client to crash. Affecte file is
1187 lib/silcclient/client_prvmsg.c.
1189 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1191 * Added function silc_client_add_channel,
1192 silc_client_replace_channel_id, and removed functions
1193 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1194 from client library.
1196 * Added cross reference of the joined channels to the
1197 SilcClientEntry, and changed the SilcChannelEntry's
1198 users list to SilcHashTable. The affected files are
1199 lib/silcclient/idlist.[ch].
1201 * Fixed a bug in hash table tarversing. While the hash table
1202 is traversed with SilcHashTableList the table must not be
1203 rehashed. It is now guaranteed that auto rehashable tables
1204 are not rehashed while tarversing the list. Also defined that
1205 silc_hash_table_rehash must not be called while tarversing
1206 the table. Added function silc_hash_table_list_reset that must
1207 be called after the tarversing is over. The affected files are
1208 lib/silcutil/silchashtable.[ch].
1210 * Changed all hash table traversing to call the new
1211 silc_hash_table_list_reset in server and in client library.
1213 * Added function silc_client_on_channel to return the
1214 SilcChannelUser entry if the specified client entry is joined
1215 on the specified channel. This is exported to application as
1216 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1218 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1220 * Fixed founder regaining problem with JOIN command on normal
1221 server. The notify for mode change must be sent always and
1222 not only if !cmd->pending. Affected file silcd/command.c.
1224 * Fixed the WHOWAS command's reply sending to support the
1225 lists correctly. Affected file silcd/command.c.
1227 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1229 * When sending JOIN command to router for processing the
1230 sender's old command identifier was not saved back to the
1231 sender's command context, fixed now. The affected file is
1234 * Create the key in JOIN command of the router did not return
1235 the channel key, added check for this. Affected file is
1238 * Fixed a channel ID update bug in JOIN command reply. Do
1239 not directly upgrade the ID but call the function
1240 silc_idlist_replace_channel_id if the ID was changed.
1241 Affected file silcd/command_reply.c.
1243 * Fixed memory leaks from command calling if it would fail.
1244 Affected file silcd/command.c.
1246 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1248 * Applied patches from cras:
1250 Memory leak fixes around libaries, irssi window resize fix,
1251 new silclist.h and silcdlist.h, all extern inline changed to
1254 * Removed dotconf from lib/dotconf, not needed anymore.
1256 * Removed TRQ from lib/trq, not needed anymore.
1258 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1259 with server connections. Later this will be configurable
1260 in config file after new config file is done. Affected file
1263 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1265 * Fixed a crash in server related to channel announcements.
1266 Affected file silcd/server.c.
1268 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1270 * Fixed memory leaks in silc_server_create_new_channel*
1271 functions. Affected file silcd/server.c.
1273 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1274 which ID was changed. This way the router will send the
1275 user list for the channel again, and server won't be in
1276 desync in some rare circumstances. Affected file is
1277 silcd/packet_receive.c.
1279 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1281 * Check for NULL socket pointer in the function
1282 silc_server_packet_send_to_channel_real. Affected file
1283 silcd/packet_send.c.

1286 list. Affected file silcd/packet_receive.c.
1288 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1290 * Fixed some header addition to Toolkit distribution in
1291 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1293 * Added lib/silcclient/client_ops_example.h as an template
1294 file for application programmers to quickly start using
1295 the SilcClientOperation functions in their application.
1296 Updated the lib/silcclient/README as well to tell about this
1297 nice file made available.
1299 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1301 * Call silc_server_remove_from_channels when removing client
1302 entry when NO_SUCH_CLIENT_ID was received. Affected file
1303 is silcd/command_reply.c.
1305 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1307 * Added server & router operator statistics updating. Affected
1308 file silcd/packet_receive.c and silcd/command.c.
1310 * Fixed the SERVER_SIGNOFF notify handling on normal server
1311 not to save the history information for clients. Same was
1312 fixed earlier in remove_clients_by_server function, but not
1313 here. Affected file silcd/packet_receive.c.
1315 * Raised the default connection-retry count from 4 to 7 in
1316 server. Affected file silcd/server.h.
1318 * Cancel any possible reconnect timeouts when we start the
1319 key exchange. Affected file silcd/server.c.
1321 * Do not reconnect on connection failure when SCONNECT was
1322 given. Affected files silcd/server.[ch].
1324 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1326 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1328 * Fixed the NICK command to always give the unformatted
1329 nickname to the one giving the NICK command. If unformatted
1330 nickname is cached already it will be formatted and the
1331 local entry will always get the unformatted nickname.
1332 Affected file lib/silcclient/idlist.c.
1334 * Fixed some double frees from client library commands.
1335 Affected file is lib/silcclient/command.c.
1337 * Fixed CUMODE command in server to assure that no one can
1338 change founder's mode than the founder itself, there was a
1339 little bug. Affected file silcd/command.c.
1341 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1343 * Removed the SilcClientCommandDestructor from the client
1344 libary, it is not needed anymore. Affected files are
1345 lib/silcclient/silcapi.h, command[_reply].[ch],
1346 client_notify, idlist.c.
1348 * Fixed GETKEY command to first resolve client, and then
1349 resolve the server only if the client was not found, instead
1350 of resolving both at the same time. Affected file is
1351 lib/silcclient/command.c.
1353 * Added silc_client_start_key_exchange_cb and lookup the
1354 remote hostname and IP address before starting the key
1355 exchange with server. The affected file is
1356 lib/silcclient/client.c.
1358 * The server's public key is now saved using the IP address
1359 of the server and not the servername for the filename.
1360 The hostname public key filename is checked as an fall back
1361 method if the IP address based filename is not found.
1363 Fixed the GETKEY command to save the fetched server key
1364 in correct filename.
1366 Print the remote server's hostname now when new key is
1367 received during connection process. Affected file is
1368 irssi/src/silc/core/client_ops.c.
1370 * Return always our own public key to the client if it asks
1371 for it with GETKEY command. Affected file silcd/command.c.
1373 * Removed the use_auto_addr variable from default config
1374 file since it was in wrong section. Affected file is
1377 * Fixed TOPIC_CHANGE notification to not route it when it
1378 was sent using silc_server_send_notify_to_channel function.
1379 Affected file silcd/command.c.
1381 * Fixed silc_server_send_notify_kicked to send the kicker's
1382 Client ID also, it was missing. Affected files are
1383 silcd/command.c, silcd/packet_send.[ch].
1385 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1387 * Do not save client history information in SERVER_SIGNOFF.
1388 Fixes the bug in normal server that it does not detect
1389 the client becoming valid after the server becomes back
1390 online. Affected file silcd/server_util.c.
1392 * Added `sock_error' field into the SilcSocketConnection
1393 context. When error occurs during socket operation (read
1394 or write) the error is saved. Added also new function
1395 silc_socket_get_error to return human readable socket error
1396 message. Affected files are lib/silcutil/silcsockconn.[ch],
1397 lib/silcutil/unix/silcunixsockconn.c, and
1398 lib/silcutil/win32/silcwin32sockconn.c.
1400 * The server now prints the socket error message in the
1401 signoff for client. Affected file silcd/server.c.
1403 * Fixed the `created' channel information sending from router
1404 to server in JOIN command. Checks now whether the channel
1405 really was created or not and set it according that.
1407 Fixed the JOIN command to use the client entry's current
1408 ID during the joining procedure instead of the one it sent
1409 in the command (it is checked though), since it can change
1410 between the packet processing and command processing, and
1411 would just case unnecessary pain in the client end. Affected
1412 file silcd/command.c.
1414 * Fixed a channel key payload sending to use correct channel
1415 ID when the server was forced to change the channel's ID by
1416 router. Router sent the key payload with the old Channel ID.
1417 Affected file silcd/packet_receive.c.
1419 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1421 * Call silc_server_save_channel_key only if the key payload
1422 was provided in the JOIN command's command reply. Affected
1423 file silcd/command_reply.c.
1425 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1427 * Fixed silc_mp_sizeinbase to return the value correctly with
1428 MPI. Affected file lib/silcmath/mp_mpi.c.
1430 * Fixed the stop_server signal to correctly stop the scheduler
1431 and gracefully stop the server when SIGTERM or SIGINT signals
1432 are received. Affected file silcd/silcd.c.
1434 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1436 * Simple handling of TERM and HUP signals. Also added some log
1437 flushing call around. Affected file is
1440 * Fixed small bugs in silclog.c. Now buffering output will take
1441 effect after 10 seconds since startup: This will ensure that
1442 no important startup messages are lost. Also output redirection
1443 will preserve original format ([Date] [Type] message).
1444 Affected file is lib/silcutil/silclog.c.
1446 * Added two options to the config file, in the logging section:
1447 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1448 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1450 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1452 * Do not print the warning about log files not being initialized
1453 more than once to avoid excess logging. Affected file is
1454 lib/silcutil/silclog.c.
1456 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1457 the SIM copying in make install in Makefile.am.pre.
1459 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1461 * Rewritten silclog APIs. Globally interesting changes follows:
1462 silc_log_set_files() changed to silc_log_set_file().
1463 silc_log_set_callbacks() changed to silc_log_set_callback().
1464 ROBOdoc documented silclog header file.
1465 SilcLogCb now returns bool to wether inihibit the default
1466 handler or not (to keep the old behaviour return always TRUE).
1467 The new APIs should also fix the problem of the
1468 silcd_error.log file that was written in the current directory.
1471 Log files streams will remain opened after silc_log_set_file()
1472 call, means less CPU usage notably on high traffic servers.
1473 File streams are now full buffered, and flushed to the disk
1474 every 5 minutes, lesses HD activity and CPU usage.
1475 Messages can be redirected, allowing admins to configure
1476 one single logfile for all server messages.
1477 the silc_log_quick global variable to activate fast-logging.
1478 Affected files lib/silcutil/silclog.[ch]
1480 * Changed some code to conform new silclog APIs. Affected
1481 files are doc/example_silcd.conf.in, silcd/server.c
1482 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1485 * Fixed a memory leak that could occur in some situations.
1486 Affected file silcd/serverconfig.c.
1488 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1490 * Added the silc_client_del_client to remove the client from
1491 all channels as well. Affected file lib/silcclient/idlist.c.
1493 * Fixed the client library to correctly remove the client
1494 from all channels when the client entry is being destroyed.
1495 Affected file lib/silcclient/client_notify.c, command.c.
1497 * Added auto-nicking support to the client library. If the
1498 applicatio now sets client->nickname it will be sent to the
1499 server after connecting by the library. This way for example
1500 SILCNICK (or IRCNICK) environment variables will have effect
1501 and always change the nickname automatically to whatever
1502 it is wanted. Affected file lib/silcclient/client.[ch].
1504 * Renamed silc_server_command_bad_chars to the
1505 silc_server_name_bad_chars and moved it to the
1506 silcd/server_util.[ch]. Added also new function
1507 silc_server_name_modify_bad to return nickname that
1508 includes bad characters as new nickname without those
1509 bad characters. This check and modify is now used in
1510 silc_server_new_client when the username is initially set
1511 as nickname, so it must be checked to be valid nickname.
1512 Affected file silcd/packet_receive.c.
1514 * The nickname length is now taken from the packet for real
1515 and not trusted to strlen() since it clearly can return
1516 wrong length for nickname including bad characters. This
1517 also applies to channel names. Affected file silcd/command.c.
1519 * Removed the lib/silcsilm/modules directory. Modules are now
1520 compiled into the lib/silcsim. Fixed the copying of the
1521 modules to follow symbolic links in Makefile.am.pre.
1523 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1525 * Fixed silc_string_regexify list creation. Fixes bugs with
1526 BAN and INVITE commands in server. The affected file is
1527 lib/silcutil/unix/silcunixutil.c.
1529 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1531 * Removed the command destructor entirely from the server's
1532 command and command reply routines. It is not needed, and
1533 its usage was buggy and caused crashes. Affected files are
1534 silcd/command[_reply].[ch].
1536 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1538 * Cancel protocol and NULL sock->protocol if timeout
1539 occurred during protocol. Affected file silcd/server.c.
1541 * Cancel protocol timeouts always before calling the final
1542 callback, to assure that after final callback is called
1543 no other state will be called for the protocol anymore.
1544 Affected file silcd/protocol.c.
1546 * Print error log if incoming connection configuration could
1547 not be found. Affected file silcd/server.c.
1549 * Fixed JOIN command to correctly save the founder mode
1550 to the client on normal SILC server, when the channel
1551 was created by the router. Affected file silcd/command.c.
1553 * Fixed LIST command (hopefully) to send correct reply
1554 packets. Affected file silcd/command.c.
1556 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1558 * The silc_packet_receive_process now returns FALSE if the
1559 read data was invalid packet, and TRUE if it was ok.
1561 The server now checks that if unauthenticated connection
1562 sends data and its processing fails the server will close
1563 the connection since it could be a malicious flooder.
1565 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1567 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1569 * Make sure the warning about error opening a log file is
1570 printed only once and not everytime it fails (produces
1571 too much useless log). Affected file lib/silcutil/silclog.c.
1573 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1575 * Made the silc_server_daemonise() function more readable.
1576 Affected file silcd/server.c.
1578 * Pid file is now optional, the user may comment it out from
1579 the config file. Removed define SILC_SERVER_PID_FILE, we
1580 don't need a default any longer. Affected file
1581 configure.in.pre, lib/Makefile.am.pre.
1583 * Make some use of the pid file. The server now dies at startup
1584 if it detects a valid pid file on his path. The server would
1585 die anyway in this circumstance, because of the bind() failure.
1586 Affected file silcd/silcd.c.
1588 * No longer compiling lib/dotconf.
1590 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1592 * Fixed JOIN command parsing not to crash. Affected file
1593 lib/silcclient/command.c.
1595 * Fied the NICK_CHANGE notify to add the new client entry
1596 even it is resolved. This removes an <[unknown]> nick
1597 thingy bug in the client. Affected file is
1598 lib/silcclient/client_notify.c.
1600 * Do not try to allocate 0 bytes (efence does not like it)
1601 in lib/silccore/silccomand.c when encoding payload.
1603 * Do not take IRCNICK as nickname in Irssi SILC client since
1604 it is not possible to set nickname before hand connecting
1605 the server (TODO has an entry about adding auto-nicking
1608 * Changed the silc_server_command_pending to check whether
1609 there already exists an pending entry with the specified
1610 command, command identifier and pending callback. This is
1611 to fix IDENTIFY and WHOIS related crashes that may register
1612 multiple pending commands with same identifier. Affected
1613 file silcd/command.c.
1615 * Fixed the server to reconnect to the router even if it
1616 was already reconnecting and EOF was received. This to
1617 fix a possibility that the server wouldn't ever try to
1618 auto-reconnect to the router. Affected file silcd/server.c.
1620 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1622 * Fixed the server's password authentication to use the
1623 length of the locally saved password, and not the one
1624 sent in the packet. Affected file silcd/protocol.c.
1626 * Fixed same password authentication problem in the
1627 Authentication Payload handling routines in
1628 lib/silccore/silcauth.c.
1630 * Yet another password authentication problem fixed with
1631 channel password handling in silcd/command.c.
1633 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1635 * If first character of string in silc_parse_userfqdn is '@'
1636 then do not parse it. Affected file is
1637 lib/silcutil/silcutil.c.
1639 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1641 * Fixed minor bug in IDENTIFY command reply sending, which
1642 caused various weird problems during JOIN when it was
1643 resolving names for users. Affected file silcd/command.c.
1645 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1647 * Fixed the IDENTIFY command reply sending to chech better valid
1648 clients. It was possible to send incomplete list of replies.
1649 Affected file silcd/command.c.
1651 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1653 * Added silc_client_command[s]_[un]register functions now to
1654 dynamically register the commands in client library. Removed
1655 the static table of commands. This allows the client library
1656 to call commands without causing the application to know about
1657 what commands library has called.
1659 Removed the INFO command reply kludge to detect when the command
1660 was called by library. Now library use its own command reply
1661 function for INFO command.
1663 Added function silc_client_command_call to call a command.
1664 Application can use it to call command, not access the structure
1667 Now all commands that are sent by the client library (not
1668 explicitly sent by application) use own command reply functions.
1670 Affected files around lib/silcclient/ and in
1671 irssi/src/silc/core/.
1673 * Fixed the WHOIS command reply sending to chech better valid
1674 clients. It was possible to send incomplete list of replies.
1676 Fixed the WHOIS and IDENTIFY to send the request to router
1677 if normal server did not do it and did not find any results.
1679 Affected file silcd/command.c.
1681 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1683 * Moved the internal data from SilcClient context into its
1684 own file, not accesible to application. Affected files
1685 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1686 and other files in client library.
1688 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1690 * Added doc/examples installation target in Makefile.am.pre.
1693 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1695 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1696 commands the found client entry will be removed from the
1697 cache, after notifying application about the error. Affected
1698 file lib/silcclient/command_reply.c.
1700 * Changed the /MSG to check for exact nickname user gave, and
1701 not let `nick' match `nick@host' if it is only one found. Now,
1702 user must type the exact nickname (like nick@host2) even if
1703 there are no more than one same nicks found. This is to avoid
1704 a possibility of sending nickname to wrong nickname since
1705 `nick' could match `nick@host'. Affected file is
1706 irssi/src/core/silc-servers.c.
1708 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1710 * Do not print "you are now server operator" or similar when
1711 giving /away command. Affected files are
1712 irssi/src/silc/core/client_ops.c, silc-servers.h.
1714 * Made the silc_server_command_pending_error_check to send
1715 the same command reply payload it received back to the
1716 original sender of the command. This way all arguments
1717 that was received by the server will be received by the
1718 client too. Affected file silcd/command.c.
1720 * Added the silc_idcache_add to return the created cache entry
1721 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1723 * Add global clients to expire if they are not on any channel.
1724 This is because normal server will never know if they signoff
1725 if they are not on any channel. The cache expiry will take
1726 case of these entries. This is done by normal servers only.
1727 The affected files are silcd/command_reply.c,
1728 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1730 * If server receives invalid ID notification for WHOIS or
1731 IDENTIFY and the ID exists in the lists, it is removed.
1732 Affected file silcd/command_reply.c.
1734 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1735 in client then client entry that it matches is searched and
1736 the nickname is printed on the screen for user. Affected
1737 file irssi/src/silc/core/client_ops.c.
1739 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1741 * Use cache entry expire time in the LIST command reply to
1742 purge old entries from the cache after the LIST command
1743 reply has been received. This way we don't have non-existent
1744 entries in the cache for too long. Affected file is
1745 silcd/command_reply.c.
1747 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1749 * If we are normal server, and we've not resolved client info
1750 in WHOIS or IDENTIFY from router, and it is global client,
1751 we'll check whether it is on some channel. If it is not
1752 then we cannot be sure about its validity and will resolve it
1753 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1754 file silcd/command.c.
1756 * Search channel by name (if possible) rather than by ID
1757 in IDENTIFY command's command reply. Affected file is
1758 silcd/command_reply.c.
1760 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1762 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1763 Updated specs and implemented it. Affected file silcd/command.c,
1764 silcd/packet_send.c and silcd/packet_receive.c.
1766 * Implemented the <founder auth> payload handling in the JOIN
1767 command. If provided all conditions for channel joining
1768 except requirement to provide correct passphrase can be
1769 overrided by the channel founder. Updated the protocol specs.
1770 Affected file silcd/command.c.
1772 Added support for founder auth in JOIN command in client
1773 library. Fixed the parsing of the JOIN command now to support
1774 all options as they should be. The affected file is
1775 lib/silcclient/command.c.
1777 * Optimized the WHOIS and IDENTIFY commands to send the request
1778 to router only if it includes nicknames or other names. If
1779 they include only IDs then check the local cache first before
1780 routing. Affected file is silcd/command.c.
1782 * Added channels topic announcements. Affected file is
1783 silcd/packet_receive.c and silcd/server.c.
1785 * Fixed the silc_server_send_notify_topic_set to really destine
1786 the packet to channel. Affected file silcd/packet_send.c.
1788 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1789 library. Affected file lib/silcclient/client_notify.c.
1791 * Added UMODE announcements. Affected file silcd/server.c.
1793 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1795 * Memory leak fixes in:
1797 lib/silcutil/silcsockconn.c
1798 lib/silcske/silcske.c
1799 lib/silcske/groups.c
1801 lib/silccrypt/silcpkcs.c
1802 lib/silccore/silccommand.c
1803 lib/silccore/silcidcache.c
1808 * ROBOdoc documented the lib/silcske/groups.h file and a
1809 bit changed the interface for better.
1811 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1813 * Update the client entry context in the ID cache after
1814 nick change. Affected file lib/silcclient/command.c.
1815 Fixes the CUMODE command when regaining founder privileges,
1816 and a little WHOIS problem.
1818 * Fixed silc_net_gethostbyname to correctly call the
1819 inet_ntop. Affected file lib/silcutil/silcnet.c.
1821 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1823 * Added IPv6 support checking to the configure.in.pre, added
1824 also --enable-ipv6 option to override the check. Affected
1825 file configure.in.pre.
1827 * The silc_thread_create now calls the start function
1828 directly if threads support is not compiled in. Removes
1829 ugly #ifdef's from generic code. Affected files are
1830 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1832 * Added silc_net_gethostby[name/addr]_async to asynchronously
1833 resolve. Affected files are lib/silcutil/silcnet.[ch].
1835 * Added support for rendering IPv6 based server, client and
1836 channel IDs. Affected file lib/silcutil/silcutil.c.
1838 * Added support for creating IPv6 based server IDs. Affected
1839 file is silcd/serverid.c.
1841 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1843 * Added silc_net_gethostby[addr/name] into the
1844 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1845 routines. Added silc_net_is_ip[4/6]. Affected file is
1846 lib/silcutil/unix/silcunixnet.c. All routines that take
1847 address as argument now supports both IPv4 and IPv6 addresses.
1849 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1851 * Fixed LIST command reply sending in server. Affected file
1854 * Server now sends the kicker's client ID in the KICK notify
1855 to the kicked client. Affected file silcd/command.c.
1857 * The client library now parses the kickers client ID and
1858 UI displays it. Affected files lib/silcclient/client_notify.c
1859 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1861 * Made all payload parsing function prototypes consistent.
1862 They all take now const unsigned char * and uint32 pair as
1863 the payload data instead of SilcBuffer. Changes all around
1864 the source tree. Other unsigned char* -> const unsigned char*
1865 changes around the tree as well.
1867 * Optimized SFTP client and server packet sending not to
1868 allocate new buffer for each packet but to recycle the
1869 first allocated buffer. Affected files are
1870 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1872 * Optimized the SFTP client to use SilcList instead of
1873 SilcDList for requests, because it is faster. Affected file
1874 is lib/silcsftp/sftp_client.c.
1876 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1877 into lib/silccore/silcid.[ch].
1879 Renamed silcpayload.[ch] into silcargument.[ch].
1881 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1883 * If client entry is deleted with active key agreement
1884 session, abort the session.
1886 The silc_client_abort_key_agreement now calls the completion
1887 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1889 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1892 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1894 * Don't use __restrict in older GCC's. Affected file is
1895 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1897 * silc_net_localhost now attempts to reverse lookup the
1898 IP/hostname. Affected file lib/silcutil/silcnet.c.
1900 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1901 command. It can be used to gain founder privileges at
1902 the same time when joining the channel.
1904 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1905 kicker's client ID as well. Updated protocol specs.
1907 Defined that the server must send SILC_COMMAND_IDENTIFY
1908 command reply with error status to client who sent
1909 private message with invalid client ID.
1911 Updated the protocol specification.
1913 * Added silc_server_send_command_reply to send any
1914 command reply. Affected file silcd/packet_send.[ch].
1916 * Added silc_id_payload_encode_data to encode ID payload
1917 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1919 * The server now send IDENTIFY command reply with error
1920 status if client ID in private message is invalid. Affected
1921 file silcd/packet_receive.c.
1923 * Save the server key file with server's IP address in
1924 the filename instead of hostname. The affected file is
1925 irssi/src/silc/core/client_ops.c.
1927 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1932 * Added libtool support for compiling shared objects in
1933 lib/silcsim. Affected file configure.in.pre and
1934 lib/silcsim/Makefile.am. Original patch by cras.
1936 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1938 * Pid file configuration, and server's config file fixes
1939 patch by toma. Updated CREDITS file.
1941 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1943 * Fixed silc_client_channel_message to not try to decrypt
1944 the message twice if it resolved the destination client
1945 information. This could cause of dropping one channel
1946 message. Affected file lib/silcclient/client_channel.c.
1948 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1950 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1951 lib/silcclient/client.c. This function is used when the SILC
1952 Client is run under some other scheduler, or event loop or
1953 main loop. On GUI applications, for example this may be
1954 desired to used to run the client under the GUI application's
1955 main loop. Typically the GUI application would register an
1956 idle task that calls this function multiple times in a second
1957 to quickly process the SILC specific data.
1959 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1961 * Fixed silc_server_drop() for dropping the supplementary
1962 groups as well, this could cause a security hole on some
1965 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1967 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

1978 Affected file irssi/src/silc/core/client_ops.c.
1980 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1982 * Fixed the silc_idcache_list_* routines to really support
1983 the dynamic list. Fixes a crash. Affected file is
1984 lib/silccore/silcidcache.c.
1986 * Fixed the LIST command reply to really call LIST command's
1987 pending callbacks. Affected file silcd/command_reply.c.
1989 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1991 * Update conn->local_entry->nickname after giving NICK
1992 command. Affected file lib/silcclient/command.c.

1996 * Added the [pid] option to the silcd configuration file
1998 Affected files: serverconfig.[ch] and silcd.c
2000 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2002 * Save fingerprint in WHOIS command reply in server.
2003 Affected file silcd/command_reply.c.
2005 * Fixed NICK commands pending callback registration.
2006 Affected file lib/silcclient/command.c.
2008 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2010 * Use ++server->cmd_ident when sending commands in server,
2011 instead of random number. Affected file silcd/command.c.
2013 * Fixed GETKEY command reply to call actually GETKEY pending
2014 command callbacks. Affected file silcd/command_reply.c.
2016 * A bit stricter check for nicknames. Check for same nickname
2017 in NICK command also. Affected file silcd/command.c.
2019 * Do not call INFO command everytime client ID changes, only
2020 during first connecting. Affected file lib/silcclient/client.c.
2022 * Set the new nickname only after successful command reply for
2023 NICK command is returned by server. Affected file
2024 lib/silcclient/command.c.
2026 * Remove nicknames from nicklist during server_signoff notify.
2027 Should fix /NAMES bit more. The affected file is
2028 irssi/src/silc/core/silc-channels.c.
2030 * Added `fingerprint' field to the SilcIDListData in the
2031 silcd/idlist.h to hold the fingerprint of the client's
2034 Send the fingerprint of the client's public key in WHOIS
2037 Affected files silcd/command.c, and silcd/idlist.[ch].
2039 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2040 create fingerprint from given data.
2042 * Show the fingerprint of the client's public key in WHOIS.
2043 Affected files irssi/src/module-formats.[ch] and
2044 irssi/src/silc/core/client_ops.c.
2046 * Format the multiple same nicknames also during JOIN and
2047 NICK_CHANGE notifys. Affected file is
2048 lib/silcclient/client_notify.c.
2050 * Do not print error on screen for invalid private message
2051 payload since it can come if someone is sending private
2052 messages with wrong key. Affected file
2053 lib/silccore/silcprivate.c.
2055 * Fixed multiple concurrent /PING crash. Affected file
2056 lib/silcclient/command.c.
2058 * Changed the wrong ID encoding. All IP addresses must be
2059 in MSB first order in encoded format. They were encoded
2060 wrong and was in LSB format. Affected files are
2061 silcd/serverid.c, lib/silcutil/silcutil.c.
2063 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2065 * Call the `connect' client operation through the scheduler
2066 in case of error. Affected file lib/silcclient/client.c.
2068 * Call the `failure' client operation even if the error
2069 occurred locally during a protocol. Affected file is
2070 lib/silcclient/protocol.c.
2072 * Added support of sending LIST command to router from normal
2073 server. This way normal server can get list of all channels
2074 in the network too. Fixed the channel list sending in the
2075 server too. Affected files are silcd/command.c, and
2076 silcd/command_reply.[ch].
2078 * Added silc_server_update_channels_by_server and
2079 silc_server_remove_channels_by_server. They are used during
2080 disconnection of primary router and in backup router protocol.
2081 Affected file silcd/server_util.[ch], silcd/server.c and
2082 silcd/server_backup.c.
2084 * Fixed channel adding to global list in IDENTIFY command
2085 reply in server. Affected file silcd/command_reply.c.
2087 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2089 * If the incoming packet type is REKEY or REKEY_DONE process
2090 that packet always synchronously. Fixes yet another MAC
2091 failed error on slow (dialup) connections. Affected file
2092 lib/silcclient/client.c and silcd/server.c.
2094 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2096 * Call check_version SKE callback for initiator too. Affected
2097 file lib/silcske/silcske.c.
2099 * Implemented fix for security hole found in the SKE that was
2100 fixed in the specification few days back; the initiator's
2101 public key is now added to the HASH value computation.
2102 Added backwards support for the old way of doing it too, for
2103 old clients and old servers. Affected file is
2104 lib/silcske/silcske.c.
2106 * Enabled mutual authentication by default in SKE. If initiator
2107 is not providing mutual authentication the responder will
2108 force it. This will provide the proof of posession of the
2109 private key for responder. The affected files are
2110 lib/silcclient/protocol.c and silcd/protocol.c.
2112 * Do not cache anymore the server's public key during SKE.
2113 We do mutual authentication so the proof of posession of
2114 private key is done, and if the server is authenticated in
2115 conn auth protocol with public key we must have the public
2116 key already. Affected file silcd/protocol.c.
2118 * Added new global debug variable: silc_debug_hexdump. If
2119 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2120 file lib/silcutil/silclog.[ch].
2122 * Fixed compilation warning due to char * -> const char *.
2123 Affected files lib/silcutil/silcnet.h, and
2124 lib/silccore/silcauth.[ch].
2126 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2128 * Fixed CMODE command when new channel key was created. If
2129 the creation failed the old key was removed. Next time giving
2130 same command would crash the server since the old key was
2131 freed already. Affected file silcd/command.c.
2133 * Fixed the silc_server_announce_get_channels to not crash
2134 on reconnect. Affected file silcd/server.c.
2136 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2138 * Added silc_log_set_debug_string function to set a regex
2139 string to match for debug output. Only the function names,
2140 or filenames matching the given debug string is actually
2141 printed. This way it is possible to filter out those debug
2142 strings that user is not interested in.
2144 Fixed a bug in silc_string_regexify.
2146 Affected files lib/silcutil/silclog.[ch], and
2147 lib/silcutil/unix/silcunixutil.c.
2149 * Changed the -d options in both server and Irssi SILC client
2150 to take the debug string as argument. Affected files
2151 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2153 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2155 * Added silc_hash_babbleprint to create a Bubble Babble
2156 Encoded fingerprint. The encoding is developed by Antti
2157 Huima (draft-huima-babble-01.txt), and it creates human
2158 readable strings out of binary data. Affected file
2159 lib/silccrypt/silchash.[ch].
2161 * Print the babble print now in addition of fingerprint as well
2162 in Irssi SILC client. Affected files are
2163 irssi/src/fe-common/silc/module-formats.[ch],
2164 irssi/src/fe-common/silc/core/client_ops.c.
2166 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2168 * Fixed a security problem found in SKE. The initiator's
2169 public key too is now added to the HASH hash value creation
2170 which is signed by the responder to create the SIGN value.
2171 This will prevent anyone in the middle to lie to the responder
2172 about the initiator's public key. If this is done now, the
2173 man in the middle will get caught. Updated the protocol
2176 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2178 * Better installation directory handling. Configure module
2179 paths and other paths automatically to example_silc* files
2180 in doc/. A patch by toma.
2182 * Fixed compiler warning from MPI library, and from SILC RNG.
2185 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2186 It can be configured with ./configure. A patch by toma.
2188 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2190 * Find correct make to use in prepare-clean. A patch by
2191 toma. Affected file prepare-clean.
2193 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2195 * Added irssi variables use_auto_addr, auto_bind_ip,
2196 auto_bind_port and auto_public_ip.
2198 * Changed the interface for silc_client_send_key_agreement
2199 in lib/silcclient/silcapi.h
2203 irssi/src/silc/core/silc-core.c
2205 lib/silcclient/silcapi.h
2206 irssi/src/silc/core/silc-channels.c
2207 lib/silcclient/client_keyagr.c
2210 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2212 * Added silc_pkcs_public_key_compare to compare two
2213 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2215 * Check that the client who set the founder mode on the
2216 channel is the same client that is giving the founder
2217 mode to itself. It is done by comparing the saved public
2218 key (it is saved even in the authentication is passphrase).
2219 Affected file silcd/command.c.
2221 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2223 * Do not process packet for disconnected socket connection.
2224 Affected file lib/silccore/silcpacket.c.
2226 * Process the DISCONNECT packet through scheduler in the
2227 client library. Affected file lib/silcclient/client.c.
2229 * Fixed the silc_client_packet_parse to not to increase
2230 the packet sequence number if the conn->sock and the
2231 current socket connection is not same. This can happen
2232 for example during key agreement when the conn includes
2233 multiple socket connections (listeners). Affected file
2234 lib/silcclient/client.c.
2236 * The sender of the file transfer request now provides also
2237 the pointer (listener) for the key exchange protocol. If
2238 the listener cannot be created then it sends empty key
2239 agreement and lets the receiver provide the listener.
2241 Added `local_ip' and `local_port' arguments to the
2242 silc_client_file_send. If they are provided they are used,
2243 if not then it will attempt to find local IP address, if
2244 not found or bind fails then the remote client will provide
2247 Affected files are lib/silcclient/client_ftp.c and
2248 lib/silcclient/silcapi.h.
2250 * Extended the FILE SEND command to support defining the
2251 local IP and port for key exchange listener. They are
2252 optional. Affected file irssi/src/silc/core/silc-servers.c.
2254 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2256 * Defined to WHOIS command reply the sending of fingerprint
2257 of the client's public key (if the proof of posession of the
2258 corresponding private key is verified by the server).
2259 Updated to the protocol specification.
2261 * Added support of receiving the client's public key's
2262 fingerprint in command reply in client library. Affected
2263 file is lib/silcclient/command_reply.c, and
2264 lib/silcclient/idlist.[ch].
2266 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2268 * Do not send over 128 chars long nickname to the server
2269 in NICK command. Affected file lib/silcclient/command.c.
2271 * Do not send over 256 chars long channel names to the server
2272 in JOIN command. Affected file lib/silcclient/command.c.
2274 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2276 * Assure that silc_server_close_connection cannot be called
2277 twice for same socket context. Affected file is
2280 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2282 * Send error message to application if opening file for
2283 writing during file transfer fails. Affected file is
2284 lib/silcclient/client_ftp.c.
2286 Remove all file transfer sessions for a client that we're
2287 removing from ID cache.
2289 Affected file is lib/silcclient/client_ftp.c.
2291 * Fixed silc_net_addr2bin to return correct address. Affected
2292 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2294 * Fixed file transfer session removing on signoff notify.
2295 Affected file irssi/src/silc/core/silc-servers.c.
2297 * Added the SilcClientFileError to be returned in the monitor
2298 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2299 Affected file lib/silcclient/silcapi.h.
2301 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2303 * Fixed a crash in silc_client_ftp_free_sessions and
2304 silc_client_ftp_session_free_client. Affected file
2305 lib/silcclient/client_ftp.c.
2307 * Added `disabled' field in the SilcChannelEntry in the server
2308 to indicate if the server entry is disabled. Affected file
2309 silcd/idlist.h, silcd/command[_reply].c.

2312 started. Affected file silcd/silcd.c.
2314 * Added silc_server_packet_send_clients to send a packet to
2315 the provided table of client entries. Affected file
2316 silcd/packet_send.[ch].
2318 * Fixed a crash in client resolving in client_prvmsg.c in
2319 client library. Affected file lib/silcclient/client_prvmsg.c.
2321 * Do not actually remove the client directly from ID cache
2322 during SERVER_SIGNOFF, but invalidate it. This way we
2323 preserve the WHOWAS info for the client. Affected file
2324 silcd/server_util.c.
2326 * Fixed SERVER_SIGNOFF notify handling in the server. The
2327 server is now able to process incoming SERVER_SIGNOFF notify
2328 for a server that it doesn't even know about. It will remove
2329 the clients provided in the notify. Affected file
2330 silcd/packet_receive.c.
2332 * Check for partial packet in data queue after every packet that
2333 was found from the queue. Return and wait for more data if
2334 there is partial data in queue. Affected file is
2335 lib/silccore/silcpacket.c.
2337 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2339 * Added SilcClietFileError enum to indicate error in
2340 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2341 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2342 Affected files lib/silcclient/silcapi.h and
2343 lib/silcclient/client_ftp.c.
2345 * Check that newsize in silc_buffer_realloc is larger than
2346 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2348 * Added better monitor of file transfers. It now monitors
2349 key agreement protocol during the file transfer too. Added
2350 error reporting too. Affected files
2351 irssi/src/silc/core/silc-servers.c,
2352 irssi/src/fe-common/silc/module-formats.[ch].
2354 * Wrote a help file for FILE command.
2356 * Added silc_rng_global_get_byte_fast to get not-so-secure
2357 random data as fast as possible. Random data is read from
2358 /dev/urandom if available and from the SILC RNG if not
2359 available. It is used in padding generation. Affected file
2360 lib/silccrypt/silcrng.[ch].
2362 * All packets in client library are now processed synchronously.
2363 Optimized packet processing a lot. Affected file
2364 lib/silcclient/client.c.
2366 * All server connection packets are processing synchronously
2367 now in server, to optimize packet processing. Affected file
2370 * Include files are installed now only in Toolkit distribution
2371 if make install is given. Affected files: all Makefile.am's.
2373 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2375 * Assure that silc_client_notify_by_server_resolve does not
2376 resolve the client information multiple times. If it cannot
2377 be found by the first it cannot be found at all. Affected
2378 file lib/silcclient/client_notify.c.
2380 * Fixed WHOWAS command reply calling. Affected file
2381 lib/silcclient/command_reply.c.
2383 * Removed all references to silc_idlist_get_client from the
2384 Irssi SILC client since that call is internal call used by
2385 the library. The Irssi SILC client will use now client
2386 retrieval functions found in silcapi.h.
2388 * Fixed a bug in resolving nickname info before sending
2389 private message. It used freed memory. Affected file
2390 irssi/src/silc/core/silc-servers.c.
2392 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2394 * Assure my_channels statistics cannot go negative in server.
2395 Affected files silcd/server.c, silcd/server_util.c.
2397 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2399 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2401 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2403 * Win32 Toolkit changes. Affected files

2407 lib/sftp/sftp_fs_memory.c.
2409 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2411 * Added silc_net_localip to return local host's IP address.
2412 Affected file lib/silcutil/silcnet.[ch].
2414 * If key exchange or rekey protocol is active for a connection
2415 parse all packets syncronously since there might be packets
2416 in packet queue that we are not able to process without first
2417 processing packets before them. Affected file silcd/server,
2418 lib/silcclient/client.c.
2420 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2421 whether library should continue processing the packet.
2422 Affected file lib/silccore/silcpacket.h.
2424 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2425 SilcSFTPMonitorData to SFTP server to monitor various
2426 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,

2429 * Added silc_file_size to return file size. Affected file
2430 lib/silcutil/silcutil.[ch].
2432 * Implemented the file transfer support for the client library.
2433 Added preliminary support for simple client to client one-file
2434 transmission. Affected file lib/silcclient/client_ftp.c,
2435 lib/silccilent/client.[ch].
2437 * Added new local command FILE to the Irssi SILC Client.
2438 It is used to perform the file transfer. It has subcommands
2439 SEND, RECEIVE, SHOW and CLOSE. Affected files
2440 irssi/src/silc/core/client_ops.c,
2441 irssi/src/silc/core/silc-server.[ch].
2443 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2445 * Relay the SILC_PACKET_FTP in the server. Affected files
2446 silcd/server.c and silcd/packet_receive.c.
2448 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2450 * Renamed silc_file_read and silc_file_write to functions
2451 silc_file_readfile and silc_file_writefile. Added function
2452 silc_file_open and silc_file_close. Affected files
2453 lib/silcutil/silcutil.[ch].
2455 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2457 * Resolve the client info when received private message or
2458 channel message for a client which nickname we don't know.
2459 Affected files lib/silcclient/client_prvmsg.c and
2460 lib/silcclient/client_channel.c.
2462 * Do not crash in /KEY if client is not connected. Affected
2463 file irssi/src/silc/core/silc-channels.c.
2465 * Added SilcClientStatus field to the SilcClientEntry in the
2466 lib/silcclient/idlist.h.
2468 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2469 is incomplete and is being resolved, it won't be resolved
2472 Make sure also that USERS command reply does not resolve
2473 twice information. Affected file is
2474 lib/silcclient/command_reply.c.
2476 Make sure that silc_client_get_clients_by_list does not
2477 resolve twice same information.
2479 * Check for valid client->id in the silc_server_free_client_data.
2480 Affected file silcd/server.c.
2482 * Fixed /GETKEY nick@server not to crash if the server entry
2483 is not found. Affected file lib/silcclient/command.c.
2485 * Fixed the silc_server_check_cmode_rights to check the
2486 requested modes correctly. Affected file silcd/command.c.
2488 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2490 * Better checks for non-printable chars in nick added.
2491 Affected file silcd/command.c.
2493 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Call the silc_server_udpate_servers_by_server in the
2496 primary router that comes back online in the backup resuming
2497 protocol. Otherwise it routes packets wrong. Affected file
2498 silcd/server_util.[ch], silcd/server_backup.c.
2500 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2502 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2503 lib/silcutil/silcbuffmt.[ch].
2505 * Redefined the SILC packet header to include the padding
2506 length. Affected file lib/silccore/silcpacket.[ch].
2508 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2509 length for maximum padding up to 128 bytes). Affected
2510 file lib/silccore/silcpacket.h.
2512 * Removed all backwards support for old 0.5.x MAC thingies.
2513 The SILC packet header change makes it impossible to be
2514 backwards compatible.
2516 * Send the ENDING packet with timeout in the backup resuming
2517 protocol. This is to assure that all routers has connected
2518 to the primary router. Affected file silcd/server_backup.c.
2520 * Changed the RNG to take the first IV from random data. It
2521 used to take it from zero actually. Changed the RNG also
2522 to use /dev/urandom during session. /dev/random is used
2523 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2525 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2527 * Changed the SILC packet header to have the first two bytes
2528 (the packet length) encrypted. Affected files aroung the
2529 code tree, lib/silccore/silcpacket.[ch]. Removed the
2530 SilcPacketCheckDecrypt callback. It is not needed anymore
2531 since the silc_packet_receive_process will determine now
2532 whether the packet is normal or special.
2534 * Implemented the unidirectional MAC keys. Affected files
2535 lib/silcske/silcske.c, silcd/protocol.c and
2536 lib/silcclient/protocol.c.
2538 * Implemented the packet sequence number to the MAC computation.
2539 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2540 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2541 lib/silcclient/protocol.c.
2543 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Allow backup router to announce servers. All servers
2546 announced by backup router are added to the global list
2547 automatically. Update hte server's socket to our primary
2548 router also when backup router announces a server.
2549 Affected file silcd/packet_receive.c.
2551 * Do not update the client->router in the function
2552 silc_server_udpate_clients_by_server if the client is on
2553 global list. We might fail to find any specific server
2554 for locally connected clients and local cell clients. They
2555 should still use the `from' and not `to' as client->router.
2556 This fixes backup router resuming protocol. Affected file
2557 silcd/server_util.c.
2559 * Decrease channel statistics count only if the channel
2560 deletion worked. Affected files are silcd/server.c and
2561 silcd/server_util.c.
2563 * Added silc_server_update_servers_by_server to update origin
2564 of all server entries. Used during backup router protocol.
2565 Affected files silcd/server_util.[ch], silcd/server.c. and
2566 silcd/backup_router.c.
2568 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2569 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2570 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2571 lib/silccrypt/silchmac.c.
2573 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2575 * Assure that router cannot reroute the same channel message
2576 to the sender. Affected file silcd/packet_receive.c.
2578 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2580 * Made better checks that the channel message is not sent
2581 to the router it came from. Affected file is
2582 silcd/packet_send.c. Fixed memory leak too.
2584 * Announce informations for incoming router connection, but
2585 only after checking if it is replaced by backup router.
2586 Affected file silcd/packet_receive.c.
2588 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2590 * Fixed the backup resuming protocol to work in multiple
2591 router environment. Affected file silcd/server_backup.c.
2593 * Route packet only to one router in the function
2594 silc_server_packet_send_to_channel. Affected file is
2595 silcd/packet_send.c.
2597 * Fixed silc_server_send_notify_dest to set the broadcast
2598 flag. Fixed the silc_server_send_notify_topic to actually
2599 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2600 Affected file silcd/packet_send.c.
2602 * Changed the SFTP Filesystem interface. Changed the
2603 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2604 the filesystem operation function. The SilcSFTPFilesystem
2605 is now a context that is allocated by all filesystem allocation
2606 functions and it already includes the operations structure
2607 and filesystem specific context. It is given as argument
2608 now to the silc_sftp_server_start. This made the interface
2609 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2610 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2612 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2614 * Changed the backup router adding and getting interfaces
2615 in the server. The router that will be replaced by the
2616 specified backup router is now sent as argument. Affected
2617 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2620 * Added silc_net_addr2bin_ne to return the binary form of
2621 the IP address in network byte order. Affected files
2622 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2624 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2626 * Check for existing server ID in silc_server_new_server
2627 and in silc_server_connect_to_router_final and remove the
2628 old entry if it exists. Affected file silcd/packet_receive.c,
2631 * Send the channel message always to only one router, either
2632 in upstream or downstream. Affected file is
2633 silcd/packet_send.c.
2635 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2637 * Wrote the definition of the backup resuming protocol to the
2638 protocol specification.
2640 * Removed one redundant channel key generation from normal
2641 server during joining procedure. Removed one redundant
2642 channel key sending from server to router during joining
2643 procedure. Affected file silcd/command.c.
2645 * Made minor bugfixes to the backup router resuming protocol.
2646 Affected file silcd/server_backup.c, server.c.
2648 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2650 * Added --disable-asm configuration option. Affected files
2651 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2654 * Implemented the backup resuming protocol that is used to
2655 resume the primary router position in the cell after the
2656 primary router comes back online. Affected files
2657 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2658 and silcd/server_util.[ch].
2660 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2662 * Sleep two (2) seconds after sending QUIT command to server.
2663 Affected file lib/silcclient/command.c.
2665 * Assure that if outgoing data buffer is pending do not force
2666 send any data. Affected file silcd/packet_send.c.
2668 * Assure that if outgoing data buffer is pending do not force
2669 send any data. Affected file lib/silcclient/client.c.
2671 * Implemented the backup router support when the primary router
2672 goes down. The servers and routers can now use the backup
2673 router as new primary router without loosing connectivity.
2675 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2677 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2678 in the server to indicate disabled entry. All data read
2679 from the connection will be ignored and no data is sent
2680 for entry that is disabled. Affected files are
2681 silcd/idlist.h, silcd/server.c.
2683 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2685 * Created SFTP client and server test programs in the
2686 lib/silcsftp/tests directory.
2688 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2690 * Implemented memory filesystem (virtual filesystem) for
2691 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2694 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2696 * Implemented the SFTP (SSH File Transfer Protocol) to the
2697 lib/silcsftp. It includes SFTP client and SFTP server
2700 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2702 * Moved lib/silccore/silcprotocol.[ch] to the
2703 lib/silcutil library.
2705 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2706 take variable argument list pointer as argument. Affected
2707 file lib/silcutil/silcbuffmt.[ch].
2709 * Added silc_buffer_set function that is used to set data
2710 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2711 Affected file lib/silcutil/silcbuffer.h.
2713 * Changed various routines in the core library to use the new
2714 silc_buffer_set instead of allocating new buffer only for
2717 * Added 64-bit value formatting and unformatting support to the
2718 silc_buffer_[un]format routines. Affected file is
2719 lib/silcutil/silcbuffmt.[ch].
2721 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2722 to includes/bitmove.h.
2724 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2726 * Fixed channel user mode saving in client library. Affected
2727 file lib/silcclient/command[_reply].c.
2729 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2731 * Defined the file transfer to the SILC Protocol. Added
2732 new packet type SILC_PACKET_FTP and defined File Transfer
2733 Payload. The mandatory file transfer protocol is SFTP
2734 (SSH File Transfer Protocol). Affected file in addition
2735 of the internet draft is lib/silccore/silcpacket.h.
2737 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2738 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2739 is used as part of backup router protocol when the primary
2740 router of the cell is back online and wishes to resume
2741 the position as primary router.
2743 * Redefined the MAC generation keys in the protocol. The
2744 same key is not used anymore in both direction. Both
2745 direction will now use different keys for sending and
2746 receiving. This fixes a potential security flaw. This
2747 change causes incompatibilities in the protocol.
2749 * Redefined also the MAC computation from the packet.
2750 An packet sequence number is now added to the MAC
2751 computation. This prevents possible replay attacks against
2752 the protocol. This change too causes incompatibilities
2755 Added `sequence' field to the SilcPacketContext to hold
2756 the current sequence number for the packet.
2758 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2760 * Added `created' field to the SilcIDListData in the file
2761 silcd/idlist.h to indicate the time when the entry was
2764 * Added `created' field to the SilcChannelEntry too. Affected
2765 file silcd/idlist.h.
2767 * Added `creation_time' aguments to all the announcement functions
2768 in the server. If it is provided then only the entries that
2769 was created after the provided time frame are actually
2770 announced. Affected file silcd/server.[ch].
2772 * The protocol says that the Channel ID's IP address must be
2773 based on the router's IP address. Added check for this in
2774 the silc_server_new_channel when processing incoming New Channel
2775 Payload. Affected file silcd/packet_receive.c.
2777 * Print out the correct version with --version in SILC client.
2778 Affected file irssi/src/silc/core/silc-core.c.
2780 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2782 * Fixed WHOWAS command to check for completnes of the client
2783 entry always, not just when the command is coming from client.
2784 Affected file silcd/command.c.
2786 * Added new function silc_server_packet_queue_purge to purge the
2787 outgoing data queue to the network. After the function returns
2788 it is guaranteed that the outgoing packet queue is empty.
2789 Affected file silcd/packet_send.[ch].
2791 * Purge the outgoing packet queue in the rekey protocol's final
2792 callback to assure that all rekey packets go to the network
2793 before quitting the protocol. Affected file silcd/server.c.
2795 * Added silc_client_packet_queue_parse as similar function as
2796 in server to the client library. The affected file is
2797 lib/silcclient/client.c.
2799 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2801 * Splitted silcd/server.c and created silcd/server_util.[ch]
2802 for utility functions.
2804 * Added new socket flag SILC_SF_DISABLED to indicate that the
2805 connection is open but nothing can be sent to or received from
2806 the connection. Affected file lib/silcutil/silsockconn.[ch].
2807 The checking for disabled socket is checked in the low level
2808 silc_socket_write and silc_socket_read functions.
2810 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2812 * Allow only nicknames and channel names that fits into the
2813 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2815 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2817 * When processing JOIN command reply in server check that if
2818 the channel exists in our global list we'll move it the local
2819 list. Affected file silcd/command_reply.c.
2821 * Fixed the check whether client is joined on the channel already
2822 in JOIN command. Affected file lib/silcclient/command.c.
2824 * Fixed the JOIN command reply to check whether the channel
2825 already exists. Affected file lib/silcclient/command_reply.c.
2827 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2829 * Added silc_ske_status_string to map the SKE error numbers
2830 to readable strings. The affected files are
2831 lib/silcske/silcske[_status].[ch].
2833 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2835 * Do not show the private channels on the WHOIS channel list
2836 as it is not allowed by the protocol. The affected file is
2839 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2841 * Assure that the packet length digged from the actual packet
2842 is something sensible in the silc_packet_decrypt_rest_special
2843 in lib/silccrypt/silcpacket.c.
2845 * Free and NULL the allocated pointer in silc_hmac_alloc if
2846 the HMAC allocation fails. The affected file is
2847 lib/silccrypt/silchmac.c.
2849 * Print the selected security properties to the log files in
2850 the server. Affected file silcd/protocol.c.
2852 * Add SKE's reference counter even if calling the completion
2853 callback manually. Otherwise it goes negative, although it
2854 does not cause any problems. The affected file is
2855 lib/silcske/silcske.c.
2857 * Remove the client entry with short timeout after giving the
2858 KILL command. Affected file lib/silcclient/command.c.
2860 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2861 case all found clients are already disconnected (WHOWAS would
2862 found them) in the server. Affected file silcd/command.c.
2864 * Update the last_receive (time of last data received) to be
2865 updated only when received private or channel message so that
2866 the idle time showed in WHOIS makes more sense.
2868 * Added boolean field `valid' in to the SilcClientEntry in the
2869 client library to indicate whether the entry is valid or not.
2870 This fixes the nickname change bug on channel when changing
2871 the nickname to be same than the old (like nick to Nick) the
2872 nickname formatter doesn't set the new nick anymore to Nick@host.
2873 Affected file lib/silcclient/idlist.[ch].
2875 * Now actually fixed the nickname changing on disconnection.
2876 Added new function silc_change_nick to the Irssi SILC Client.
2877 Affected file irssi/src/silc/core/client_ops.c,
2878 irssi/src/silc/core/silc-nicklist.[ch].
2880 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Check that the public key exists in the GETKEY command before
2883 trying to encode it. Affected file silcd/command.c.
2885 * Print some notifications on received public keys with GETKEY
2886 command in the Irssi SILC Client. Affected files are
2887 irssi/src/fe-common/silc/module-formats.[ch],
2888 irssi/src/silc/core/client_ops.c.
2890 * Use IDENTIFY command to resolve the server information in the
2891 GETKEY command instead of INFO command. Affected file
2892 lib/silcclient/command.c.
2894 * All command reply functions in the client library now calls
2895 the pending command reply callbacks even if an error has
2896 occurred. The server has done this a long time and now it was
2897 time to move the client library to this as well. Now all
2898 errors can be delivered back to the pending command reply
2899 callbacks if necessary. Affected files are
2900 lib/silcclient/command[_reply].[ch].
2902 * Change the nickname on disconnection back to the username
2903 because in reconnect the server will enforce it to it anyway.
2904 Affected file irssi/src/silc/core/silc-servers.c.
2906 * Fixed a config file parsing bug in the Irssi SILC client.
2907 Affected file irssi/src/silc/core/clientconfig.c.
2909 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * When printing the channel mode on JOIN, verify that the
2912 channel key and channel's HMAC are valid. Affected file
2913 irssi/src/silc/core/client_ops.c.
2915 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2917 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2918 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2919 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2921 * Removed channel key rekey task deleting from the function
2922 silc_server_save_channel_key. Affected file silcd/server.c.
2923 Added explicit timeout task context instead that is used to
2924 delete the task if we are registering a new task before the
2925 new task has elapsed.
2927 * When channel key rekey occurs the client library now saves
2928 the old channel key for a short period of time (10 seconds) and
2929 is able to use it in case some is still sending channel
2930 messages encrypted with the old key after the rekey. Affected
2931 file lib/silcclient/[idlist.h|client_channel.c].
2933 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2935 * Added check to the silc_server_new_id_real to not accept
2936 new ID if it is the sender's own ID. Affected file is
2937 silcd/packet_receive.c.
2939 * Assure that we do not announce ourself or the one we've
2940 sending our announcements when we're router and are announcing
2941 servers to our primary router. Affected file silcd/server.c.
2943 * Fixed silc_server_command_identify_check_client to assemble
2944 correct WHOIS packet. It send corrupted WHOIS packet and
2945 caused problem with router to router connections. Affected
2946 file silcd/command.c.
2948 Fixed also silc_server_command_whois_check the same way
2949 as for the IDENTIFY command.
2951 * Added new SilcIDListStatus to the server in the SilcIDListData
2952 structure. The status now includes the current status of
2953 the entry (like registered, resolved etc.). Affected file
2954 silcd/idlist.[ch]. Defined a bunch of different status types
2955 as well. This replaced the old boolean registered field as well.
2957 Added resolve_cmd_ident field to the SilcClientEntry structure
2958 too so that if the entry is for example being resolved so
2959 another command may attach to the same pending command reply
2960 without requiring to resolve the same entry again. This concept
2961 should optimize the WHOIS and the IDENTIFY resolving under
2962 heavy load by taking away unnecessary resolving for entries
2963 that are being resolved already.
2965 Added support for adding multiple pending commands for one
2966 command idenfier. Affected file silcd/command[_reply].[ch].
2968 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2969 before deleting the data. Otherwise the hash table will have
2970 freed data in comparison functions. Affected file is
2971 silcd/command_reply.c.
2973 * Fixed silc_idlist_replace_client_id to add the new entry to
2974 the cache with NULL nickname. Otherwise there will be invalid
2975 memory as the nickname after the nickname is freed. Affected
2976 file silcd/packet_receive.c.
2978 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2979 saved into wrong slots because the previous number of entries
2980 was not taken into account. Affected file silcd/idlist.c.
2981 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2983 * If we are router and we receive JOIN notify to a channel that
2984 does not have any users then notified client is marked as the
2985 channel founder, as it is it. The affected file is
2986 silcd/packet_receive.c
2988 * Added to the extended hash table API's table_del_*ext functions
2989 the destructor as argument too, so that the caller can decide
2990 which destructor to use or whether to use destructor at all.
2991 Affected file lib/silcutil/silchashtable.[ch].
2993 * Fixed ID Cache purging. It actually deleted the entries from
2994 the hash table after the data was freed. The hash table ended
2995 up comparing freed memory. The affected file is
2996 lib/silccore/silcidcache.c.
2998 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3000 * Fixed Irssi SILC client's KILL command's HELP syntax.
3002 * The USERS command now resolves the detailed user information
3003 if the userinfo field is missing. Affected file is
3004 lib/silcclient/command_reply.c.
3006 * Do not print error in silc_file_read if the read file does
3007 not exist. Just silently return NULL. Affected file is
3008 lib/silcutil/silcutil.c.
3010 * Fixed the silc_log_output to not wine about NULL filename
3011 and to not create some bogus " " filename. Affected file is
3012 lib/silcutil/silclog.c.
3014 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3016 * Fixed various printing bugs on the user interface in the
3017 Irssi SILC Client. Minor changes that were forgotten from
3020 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3022 * Fixed the configure.in.pre and the compilation and distribution
3023 environment to support the new autoconf 2.52. That version is
3024 now required to compile the CVS trunk.
3026 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3028 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3029 to generally parse user@fqdn format strings. Affected file
3030 lib/silcutil/silcutil.c.
3032 * Added nickname_format and nickname_force_format fields to the
3033 SilcClientParams structure. The first one defines the format
3034 for the nicknames that the library will enforce if the receives
3035 multiple same nicknames. The second one is boolean value and
3036 can be used to force the library to always enforce the format
3037 to the nicknames regardles whether there are multiple nicknames
3038 or not. This configurable formatting was employed to flexibly
3039 support accessing multiple nicknames from the user interface.
3040 The userinterface can now set the nicknames to what ever format
3041 they prefer. Affected file lib/silcclient/silcapi.h.
3043 Added function silc_client_nickname_format to the file
3044 lib/silcclient/idlist.c. It performs the nickname formatting.
3046 Added new field `hostname´ to the SilcClientEntry context.
3047 It holds the hostname of the client. Affected file is
3048 lib/silcclient/idlist.h.
3050 * Irssi SILC Client sets the nicknames in nick@hostn format.
3051 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3052 irssi/src/silc/core/silc-core.c.
3054 The WHOIS printing now also shows both the real nickname and
3055 the formatted nickname so that user knows how to access the
3056 user if there are multiple same nicknames cached. Affected
3057 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3058 printing formatting too to take the hostname now as a separate
3059 argument. The Affected file is
3060 irssi/src/fe-common/silc/modules-formats.[ch].
3062 * Changed the silc_client_get_clients_local to accept the formatted
3063 nickname as argument. It accepts the real nickname too but the
3064 formatted nickname can be used to find the true entry from
3065 multiple entries. Affected file lib/silcclient/silcapi.h and
3066 lib/silcclient/idlist.c.
3068 * Added nickname_format_parse field to the SilcClientParams.
3069 It is a callback function provided by the application to parse
3070 the nickname out of the formatted nickname string. The library
3071 calls it to get the nickname from the formatted string. Since
3072 the application generally knows better the format of the nickname
3073 string it parses it instead of the library, even though library
3074 encodes the formatted string. If the callback function is not
3075 provided then the library will use the string as is. The
3076 affected file is lib/silcclient/silcapi.h.
3078 * All the nickname strings passed to the client library in
3079 commands are now expected to be formatted nickname strings.
3080 If the command does not support the formatted nickname string
3081 it will assume that the sent string is the actual nickname.
3082 Affected file lib/silcclient/command.c.
3084 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3086 * Added public key authentication support to OPER and SILCOPER
3087 commands in the client library. Affected file is
3088 lib/silcclient/command.c.
3090 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3092 * Changed the get_auth_methdod client operation to be asynchronous.
3093 It can be async if the application resolves the authentication
3094 method from the server during the negotiation. Added new
3095 SilcGetAuthMeth completion callback that the application will
3096 call after resolving the authentication method.
3098 Added function silc_client_request_authentication_method that
3099 the application can use to resolve the authentication method
3100 from the server. Added also SilcConnectionAuthRequest callback
3101 that the library will call after the server has replied. The
3102 application can call this function if it does not know the
3103 current authentication method.
3105 Affected files are lib/silcclient/client.c and
3106 lib/silcclient/silcapi.h.
3108 * The Irssi SILC client now automatically resolves the authentication
3109 method incase any configuration information is not present (and
3110 currently there never is). The affected file is
3111 irssi/src/silc/core/client_ops.c.
3113 * Fixed public key authentication from the client library.
3114 Affected file lib/silcclient/protocol.c. Changed also the
3115 protocol specification about the public key authentication in
3116 the connection authentication protocol. The actual data to be
3117 signed is now computed with a hash function before signing.
3119 * Fixed the public key authentication from the server as well.
3120 Affected file silcd/protocol.c.
3122 * Removed the mlock()'s from the memory allocation routines.
3123 Affected file lib/silcutil/silcmemory.c. The ./configure does
3124 not check anymore for the mlock(). Affected file is
3127 * Fixed USERS command in server to allow the execution of the
3128 command for private and secret channels if the client sending
3129 the command is on the channel. Affected file silcd/command.c.
3131 * Fixed silc_client_get_clients_local to return the clients
3132 count correctly. It could return wrong value. Affected file
3133 lib/silcclient/idlist.c.
3135 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3137 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3138 types. The assembler optimizations seemed not to like 64-bit
3139 data types. The assmebler optimizations thus are now enabled
3140 also for BSD systems as opposed to only enable them for Linux.
3142 * Do not check for threads at all on BSD systems. Affected
3143 file configure.in.pre.
3145 * Removed -n and -h options from the Irssi SILC Client since
3146 they are not used in silc.
3148 * Fixed the prime generation to assure that the first digit
3149 of the generated random number is not zero since our conversion
3150 routines does not like number strings that starts with zero
3151 digit. If zero digit is seen the random number is regenerated.
3152 This caused some corrupted RSA keys when the zero first digit
3153 was met. Affected file lib/silcmath/silcprimegen.c.
3155 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3157 * Fixed WIN32 configuration in the ./configure script.
3158 Fixed to include xti.h on environments that has it.
3159 Patches by Carsten Ilchmann and andrew.
3161 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3163 * Changed the silc_id_create_client_id to be collision
3164 resistant. It is now assured that there cannot be created
3165 two same client ID's. I suspect that some weird bugs in
3166 the server were actually caused by duplicate Client IDs.
3167 Affected file silcd/serverid.[ch]. A router receiving
3168 new ID now also assures and informs the sending server
3169 if the ID caused collision.
3171 * Changed the silc_id_create_channel_id to also assure that
3172 there are no collisions.
3174 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3176 * Statement about ignoring the Mutual Authentication flag when
3177 performing rekey with PFS was a bit misleading. It is ignored
3178 if it was set in the initial negotiation, it cannot be even
3179 set in the rekey. Fixed in the ke-auth draft. Started the
3180 new versions of the protocol drafts in the doc/.
3182 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3184 * Fixed a bug in silc_client_command_identify_save when saving
3185 new channel information. The channel name was no duplicated
3186 and caused crash on exit. Affected file is
3187 lib/silcclient/command_reply.c.
3189 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3191 * Fixed the getkey command handling in the server. Send just
3192 empty OK reply to the sender if the key could not be fetched
3193 (but everything else was ok, like the key just was not available).
3194 Changed the public key parameter to optional in the protocol
3195 specs so that empty OK reply can be sent. Affected file
3198 Added a message to Irssi SILC client to tell to user if the
3199 server did not return a public key.
3201 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3203 * Fixed a channel key regeneration bug. It registered new
3204 timeout tasks exponentially until all system resources were
3205 used. Affected file silcd/server.c.
3207 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3209 * Added the SILC Document generator to the scripts/silcdoc.
3210 It can be used to generate the Toolkit Reference Manual out
3211 of the source tree. Internally it will also use the RoboDoc
3212 generator now imported in util/robodoc.
3214 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3216 * Added couple of return's in rekey protocol if error orccurred
3217 during the protocol. The execution must be terminated.
3218 Affected file silcd/protocol.c. Also, terminate the protocol
3219 always with timeout.
3221 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3223 * The client's Client ID was created initally from the wrong
3224 nickname (it could have been in format nick@host) in the
3225 silc_server_new_client. Affected file silcd/packet_receive.c
3227 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3229 * Added some SILC_LOG_ERROR's to various error conditions
3230 if client could not be added to ID cache. Affected files
3231 silcd/packet_receive.c and silcd/server.c.
3233 * When client's sock->user_data is freed, NULL also the
3234 client->router and client->connection pointers. Added check
3235 for these pointers being NULL to various places around the
3236 code. Affected file silcd/server.c.
3238 * Added client->data.registered == TRUE checks to various
3239 places around the code to assure that unregistered client's
3240 are not handled when it is not allowed. Affected file
3243 * Added `bool registered' fields to all
3244 silc_idlist_[server|client]_get_* routines to indicate whether
3245 the fetched client needs to be registered or not. Affected
3246 file silcd/idlist.[ch].
3248 * Add your own entry as registered to the ID cache in the
3249 server. Affected file server.c.
3251 * Fixed a bug in silc_server_new_server. The SilcServer was
3252 set as the new server's context instead of SilcServerEntry.
3253 This naturally caused some weird bugs.
3255 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3257 * Do not delete the channel rekey task when adding it
3258 for in silc_server_create_channel_key.
3260 * Changed the silc_server_create_channel_key to return
3261 TRUE or FALSE to indicate the success of the channel key
3264 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3266 * Fixed MSVC++ project files and added missing files to
3267 Makefiles under win32/.
3269 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3271 * Do not add TCP_NODELAY flag if the operating system
3272 does not have it defined. Affected files are
3273 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3275 * Fixed buffer overflow from Irssi SILC Client. Affected
3276 file irssi/src/fe-common/core/themes.c.
3278 * Fixed double free in client library in the file
3279 lib/silcclient/client.c when disconnecting from server.
3281 * Applied double free patch from cras to Irssi SILC client.
3282 Affected files irssi/src/core/[modules/expandos].c
3284 * Fixed the disconnection handling to Irssi SILC Client.
3285 The application must call silc_client_close_connection
3286 in ops->connect client operation in case of failure of
3287 the connection. Affected file is
3288 irssi/src/silc/core/client_ops.c.
3290 * Do not set sock->protocol to NULL in the function
3291 silc_client_close_connection after executing the protocol's
3292 final callback since the sock might not be valid anymore.
3293 Affected file lib/silcclient/client.c.
3295 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3297 * Do not enable SILC_THREADS if the linking with libpthread
3298 did not happen. Affected file configure.in.pre.
3300 * Added notion to protocol specification that server must
3301 verify the sent authentication payload with CMODE when
3302 setting the channel founder key. Implemented it to the
3303 server. Affected file silcd/command.c.
3305 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3307 * Added _EXTRA_DIST SILC distribution variable to the
3308 distributions file. It is used to conditionally add extra
3309 files or directories to the specific distribution. Affected
3310 files ./prepare, Makefile.am.pre and distributions.
3312 Removed the `_' from the start of the distribution names.
3315 * Added README.WIN32 for instructions to compile the Toolkit
3318 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3320 * Fixed a double free in disconnection in the server. Affected
3321 file is silcd/server.c.
3323 * Fixed the lib/silcske/groups.c to work now also with GMP
3324 MP library. The string conversion did not work when using
3325 specific base and the base is indicated in the string as well.
3327 * Created win32/ directory which now includes MSVC++ specific
3328 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3329 It will appear only in the toolkit distribution
3331 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3333 * Changed the key material distribution function in case when
3334 the hash output is too short. The data is now concatenated
3335 a bit differently than it used to. Made the change to the
3336 SKE protocol specification.
3338 * Added better GMP detection to configure.in.pre. A patch
3341 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3343 * Fixed a minor bug in SKE that might cause some problem on
3344 some platforms. Affected file lib/silcske/silcske.c.
3346 * Added the cookie checking for initiator in the SKE. It checks
3347 that the responder returns the sent cookie unmodified. The
3348 affected file is lib/silcske/silcske.c. Added new SKE
3349 error type INVALID_COOKIE that can be sent during the
3350 negotiation. Fixed some memory leaks as well.
3352 * Added the "invalid cookie" error message to Irssi SILC client's
3355 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3357 * Added `task_max' field to the SilcClientParams to indicate
3358 the maximum tasks the scheduler can handle. If set to zero,
3359 default values are used. Affected file lib/silcclient/silcapi.h.
3361 * Fixed memory leaks in silc_client_close_connection. Affected
3362 file lib/silcclient/client.c.
3364 * Added silc_client_del_client_entry to client library to free
3365 all memory of given client entry. Affected file is
3366 lib/silcclient/idlist.[ch].
3368 * Added new functions silc_client_del_channel and
3369 silc_client_del_server to delete channel and server entries.
3370 Affected file lib/silcclient/[silcapi.h/idlist.c].
3372 * Removed silc_client_del_client_by_id from silcapi.h.
3374 * Fixed the INFO command to return the server's own info
3375 correctly when querying by Server ID. Affected file is
3378 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3380 * Removed the non-blocking settings in WIN32 code in the
3381 silc_sock_[read/write] and added SleepEx instead. Affected
3382 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3383 of input data is now checked with FIONREAD and ioctlsocket.
3385 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3387 * Call silc_schedule_task_del_by_context in the
3388 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3389 Affected file lib/silccore/silcprotocol.c.
3391 * Call silc_protocol_cancel for active protocols in the
3392 silc_server_close_connection if the funtion
3393 silc_server_free_sock_user_data has not been called.
3394 Affected file silcd/server.c.
3396 * Generic tasks cannot be deleted using the del_by_fd
3397 task deleting function since generic tasks does not match
3398 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3400 * Added a notion to SILCOPER help file that the SILCOPER works
3401 only on router server, not on normal server.
3403 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3405 * Added for WIN32 support for the new scheduler as well.
3406 Affected file lib/silcutil/win32/silcwin32schedule.c.
3408 * Fixed the SHA1 implementation to work on various platforms.
3410 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3412 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3413 API. It is part of the scheduler now. Everything else is
3414 as previously but some functions has changed their names.
3415 Checkout the lib/silcutil/silcschedule.h for the interface.
3416 Updated all applications to use the new interface. Affected
3417 files are lib/silcutil/silcschedule.[ch].
3419 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3421 * Found a bug in the SKE implementation. The HASH value,
3422 specified by the protocol, was not computed correctly. The
3423 public key of the responder was not added to the computation
3424 even though it is mandatory. Affected file lib/silcske/silcske.c.
3425 This unfortunately causes incompatibilities with older
3426 clients and servers.
3428 * Added WIN32 specific network init and uninit functions:
3429 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3430 the Winsock2. Affected file lib/silcutil/silcnet.h and
3431 lib/silcutil/win32/silcwin32net.c.
3433 * Set the socket always to nonblocking mode on WIN32 after
3434 reading data or writing data. Affected file is
3435 lib/silcutil/win32/silcwin32sockconn.c.
3437 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3439 * Fixed various compilation problems under WIN32. Affected
3440 files lib/silcutil/win32/silcwin32thread.c and
3441 lib/silcutil/win32/silcwin32schedule.c.
3443 * Removed all _internal.h #includes from public header
3444 files. Internal headers must never be included from
3447 Removed also the lib/silcske/payload_internal.h file.
3449 * All include files that may be needed (public and some others
3450 included by the public headers) by application developers are
3451 now copied to the ./includes directory. It does not copy any
3452 internal headers. Affected file Makefile.defines.pre and all
3453 Makefile.am's under lib/ and subdirs.
3455 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3457 * Do not change the ~/.silc directory's permissions automatically.
3458 Affected file irssi/src/silc/core/clientutil.c.
3460 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3462 * Do not cancel the protocol in silc_server_close_connection
3463 it might cause recursion. Now cancelled in the function
3464 silc_server_free_sock_user_data. Affected file silcd/server.c.
3466 * Fixed the silc_server_remove_clients_by_server to regenerate
3467 the channel keys correctly finally. Added also new function
3468 silc_server_remove_clients_channels to actually do it.
3469 Affected file silcd/server.c.
3471 * Fixed the silc_server_new_channel to not crash by giving
3472 wrong router to the new channel. Affected file is
3473 silcd/packet_receive.c.
3475 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3477 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3478 which is given as argument to the silc_client_alloc now.
3479 It can be used to configure the client and set various parameters
3480 that affect the function of the client.
3482 * The USERS command in server did not check whether the channel
3483 is private or secret. Affected file silcd/command.c.
3485 * Added new argument to the USERS command in protocol specification.
3486 The USERS command now can take the channel name as argument
3487 as well. Added support for this in client and server and
3488 updated the protocol specs.
3490 * Completed the GETKEY command in client. It can be now used
3491 to fetch also servers public key not only some clients.
3492 Affected files lib/silcclient/command[_reply].c.
3494 * Added silc_client_get_server to return server entry by the
3495 server name. Affected files lib/silcclient/silcapi.h and
3498 * Redefined the IDENTIFY command in protocol specification to be
3499 more generic. It now can be used to query information about
3500 any entity in the SILC Network, including clients, servers and
3501 channels. The query may be based either the entity's name
3502 or the ID. Added support for this in both client and server.
3504 Affected files silcd/command.c and lib/silcclient/command.c
3505 and command_reply.c.
3507 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3508 the _from_client and _from_server functions. Affected file
3511 * Added silc_client_get_channel_by_id_resolve to the file
3512 lib/silcclient/silcapi.h to resolve channel information by
3513 its ID. Added also silc_client_get_channel_by_id that
3514 does not resolve it from the server.
3516 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3518 * Added SilcServerEntry context into the client library
3519 to represent one server. The INFO command now allocates
3520 these to save the resolved server info. For now on the
3521 client library will also keep information about servers,
3522 connected and resolved with INFO.
3524 The INFO command now allocates the SilcServerEntry context
3525 and saves the server info there. The COMMAND_REPLY in
3526 the INFO now returns the parameters to application in
3527 same order as defined in the protocol specification.
3529 The entries are cached in the client->server_cache.
3531 * The INFO command is now issued after received the Client ID
3532 from the server. Affected file lib/silcclient/client.c.
3534 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3535 to the application as the mode changer might be server.
3536 It is guaranteed that NULL is not returned anymore to the
3537 application. Affected file lib/silcclient/client_notify.c.
3539 The ID Type is now also passed to the application so that
3540 it can check whether the returned entry is SilcClientEntry
3543 Added new function silc_client_get_server_by_id to return
3544 the server entry by ID. Affected files are the
3545 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3547 * Do not create the channel in the Irssi SILC Client when issuing
3548 the JOIN command but when received the sucessful JOIN command
3549 reply. Otherwise the channel might get created even though we
3550 could not join it. The Affected file is
3551 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3553 * Fixed a channel joining bug in router. The router must also
3554 check the channel modes, invite and ban lists etc. when serving
3555 the JOIN command sent by normal server. Affected file is
3556 silcd/command.c. The router now resolves the client's
3557 information from the server who sent the JOIN command if it
3558 does not know it, and processes the JOIN command only after
3561 * Changed the SilcCommandCb to take new argument; void *context2.
3562 Affected file lib/silccore/silccommand.h
3564 The second argument in the command callbacks in the server now
3565 includes the SilcServerCommandReplyContext if the command was
3566 called as pending command callback from the command reply.
3567 Otherwise it is NULL. When called as pending the status of the
3568 command reply will be checked and if it was erronous the
3569 error will be sent to the original sender of the command.
3570 This way the client always receives the error messages even
3571 though the server was actually the one who received the error
3572 when it resent the command to router, for example. Affected
3573 files silcd/command[_reply].[ch].
3575 * Fixed sending WHOWAS command's error message to client if
3576 the requested client could not be found. It was missing.
3579 * Changed the CMODE and CUMODE commands reply arguments in the
3580 protocol specification. The Channel ID is now sent in both
3581 of the commands to identify the channel. Implemented this
3582 new feature to the client and server. Affected files
3583 lib/silcclient/command_reply.c and silcd/command.c.
3585 * Made better checks for invite and ban lists in the JOIN
3586 command in server. Affected file silcd/command.c.
3588 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3590 * The server now performs the incoming host IP/DNS lookup
3591 using the silc_socket_host_lookup and thus does not block
3592 the server anymore. Affected file silcd/server.c.
3594 * Completed the multi-thread support for SILC Scheduler in
3595 the lib/silcutil/silcschedule.c.
3597 * Fixed the configure.in.pre to detect the pthread correctly
3600 * Fixed a deadlock in silc_task_queue_wakeup in the file
3601 lib/silcutil/silctask.c.
3603 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3605 * Added new function silc_schedule_wakeup that is used in
3606 multi-threaded environment to wakeup the main thread's
3607 schduler. It needs to be used when a thread adds a new task
3608 or removes a task from task queues. After waking up, the
3609 scheduler will detect the task queue changes. If threads
3610 support is not compiled in this function has no effect.
3611 Implemented the wakeup mechanism to both Unix and WIN32
3612 systems. Affected files are lib/silcutil/silcschedule.[ch],
3613 lib/silcutil/unix/silcunixschedule.c and the
3614 lib/silcutil/win32/silcwin32schedule.c.
3616 * Added new function silc_task_queue_wakeup to wakeup the
3617 scheduler by the specified task queue. Affected file
3618 lib/silcutil/silctask.[ch].
3620 * The silc_socket_host_lookup_start now wakes up the scheduler
3621 after adding the timeout task. Affected file is
3622 lib/silcutil/silcsockconn.c.
3624 * The silc_socket_host_lookup is synchronous now if the threads
3625 support is not compiled in. However, the callback is still
3626 called asyncronously through the scheduler, anyway. Affected
3627 file lib/silcutil/silcsockconn.c.
3629 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3631 * Added new function silc_socket_host_lookup to perform
3632 asynchronous IP and FQDN lookups for the socket connection.
3633 Affected files lib/silcutil/silcsockconn.[ch].
3635 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3637 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3638 that may or may not compile the mutex support in.
3640 Changed the silc_mutex_alloc interface. It allocates the
3641 mutex now to the sent pointer and returns TRUE or FALSE.
3643 Affected file lib/silcutil/silcmutex.h.
3645 * Wrote the SILC Task Queue interface to support multi-threads.
3646 Affected file lib/silcutil/silctask.[ch].
3648 * Wrote the SILC Scheduler to support multi-threads. Affected
3649 file lib/silcutil/silcschedule.c.
3651 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3653 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3654 in lib/silcutil/win32/.
3656 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3658 * Defined SILC Mutex API and SILC Thread API and implemented
3659 them for Unix. Affected files are
3660 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3661 lib/silcutil/unix/silcunixmutex.c and
3662 lib/silcutil/unix/silcunixthread.c.
3664 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3666 * Fixed the silc_server_remove_clients_by_server's channel
3667 key re-generation. The hash table handling was incorrect
3668 and would not work with many channels. Affected file is
3671 * Fixed some memory leaks around the server code.
3673 * Rewrote the silc_server_get_users_on_channel to support IPv6
3674 based Client ID's. Affected file silcd/server.c.
3676 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3677 specification. However, a separate document must be written
3678 to define the detailed signing procedure and the payload
3679 associated with the flag. Defined the flag to the
3680 lib/silccore/silcchannel.h as well.
3682 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3684 * Changed the dynamic tables to static size tables in the
3685 lib/silccrypt/silchmac.c.
3687 * Removed GCC dependencies from the code. A patch by cras.
3689 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3691 * Do not show the error "Error receiving packet bla bla"
3692 in server if it really was not an error (-2 means that reading
3693 is pending). Affected file silcd/server.c.
3695 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3697 * Fixed a possible crash in silc_server_remove_clients_by_server
3698 in silcd/server.c. Fixed there also some memory leaks.
3700 * Fixed the silc_idlist_replace_client_id. It could replace
3701 wrong key in the hash table. Affected file silcd/idlist.c.
3703 * Do not check whether there are global users on the channel
3704 if the channel->global_users is FALSE. Affected functions
3705 silc_server_remove_from_one_channel and
3706 silc_server_remove_from_channels in silcd/server.c. Also,
3707 do not check if the removed client is local as we can be
3708 sure that global client was not removed from the channel
3709 and checking for global users is not needed.
3711 * The silc_server_remove_clients_by_server now re-generates
3712 the channel keys correctly for those channels that had
3713 clients removed from them. Affected file silcd/server.c.
3715 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3717 * Found the reason of random crashes in the server. We weren't
3718 ignoring the SIGPIPE signal (which can be sent in write())
3719 and it crashed the server. Affected file silcd/silcd.c.
3721 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3723 * Assure that sock->user_data is not NULL in the function
3724 silc_server_packet_send in silcd/packet_send.c.
3726 * Disconnect the remote connection if it could not be added
3727 to any ID lists in the server. The affected file is
3730 * Check in silc_server_packet_send[_real/dest] that the
3731 socket is not disconnecting and ignore the data if it is.
3732 Affected file silcd/packet_send.c.
3734 * Define inline to __inline on native WIN32 compilation.
3735 Affected file includes/silcwin32.h.
3737 * Added some explicit type casts for inline code since MSVC
3738 require them. Affected files lib/silcutil/silcbuffer.h,
3739 lib/trq/silcdlist.h and lib/trq/silclist.h.
3741 * Print warning in log files from now on if the packet
3742 decryption fails. Affected file silcd/server.c.
3744 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3746 * Changed the `say' client operation's interface to accept
3747 new `type' argument to indicate the type of the message sent
3748 by the library. The application may filter the library's
3749 messages according the type. The affected file is the
3750 lib/silcclient/silcapi.h.
3752 * Added two new functions to lib/silcclient/silcapi.h:
3753 silc_client_del_client and silc_client_del_client_by_id.
3754 Affected file lib/silcclient/idlist.c.
3756 * Moved the clientincludes.h from includes/ to silc/ and
3757 serverincludes.h from includes/ to silcd/.
3759 * The modes for the CMODE and CUMODE are now passed as
3760 uint32 for application with COMMAND_REPLY. The affected
3761 file is lib/silcclient/command_reply.c.
3763 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3765 * /WHOIS without arguments shows client's own information.
3766 Affected file lib/silcclient/command.c.
3768 * Changed PING to not accept any arguments. The specs
3769 says that client can ping only the connected server so
3770 requiring an argument is not needed. Affected file is
3771 lib/silcclient/command.c.
3773 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3775 * Fixed a fatal bug in private message sending and reception
3776 encryption and decryption when using private message keys.
3777 The implementation was incorrect and did not follow the
3778 specification. It causd that some of the message were
3779 lost since it did not use the sending and receiving keys
3780 as the protocol suggests. This has been fixed and will cause
3781 incompatibilities with older clients when sending private
3782 message encrypted with private message keys. Affected files
3783 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3784 and various other in Irssi SILC Client.
3786 Added `responder' boolean argument to the functions
3787 silc_client_add_private_message_key[_ske] to indicate when
3788 the key is added as responder or initiator of the key
3791 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3793 * Removed the silc_ske_check_version function and created
3794 a SilcSKECheckVersion callback. Added also a function
3795 silc_ske_set_callbacks that is now used to set all SKE
3796 callbacks. The callback functions are not given to
3797 the SKE functions anymore, but this function is used to
3800 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3802 * Added `silc_version' argument to the silc_client_alloc
3803 to define the version of the application for the library.
3804 The library will use the version string to compare it
3805 against the remote host's (usually a server) version
3806 string. Affected file lib/silcclient/silcapi.h
3808 * Added the KE protocol context to Key Agreement context
3809 in client library so that we can abort the SKE if it
3810 is in process when we get timeout. Affected file is
3811 lib/silcclient/client_keyagr.c.
3813 * Do not resolve the client ID forever if it returns in the
3814 first time that such client does not exist. This was done
3815 for example with private message. Affected file is
3816 lib/silcclient/client_prvmsg.c.
3818 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3820 * Do not add regex.h for WIN32. The affected file
3821 includes/silcincludes.h.
3823 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3824 not work yet 100%. It generates the DLL's automatically
3825 when compiling with --with-win32 under cygwin.
3827 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3829 * lib/contrib/regex.c is not compiled on WIN32.
3831 * Added silc_net_get_socket_opt function to the
3832 lib/silcutil/silcnet.h.
3834 * Added includes/silcwin32.h for WIN32 specific includes
3837 * Do not use ptime structure or any of the posix process
3838 functions on WIN32 in lib/silccrypt/silrng.c.
3840 * Added silc_gettimeofday to provide generic function
3841 for struct timeval on all platforms. Added the function
3842 to lib/silcutil/silcutil.h.
3844 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3846 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3847 library as they clearly belong there. As a plus side we
3848 can make the actual socket connection routines platform
3851 Added also new generic function silc_socket_read and
3852 silc_socket_write (that used to be silc_packet_[read/write].
3853 The implementation of these are platform specific.
3855 * Added WIN32 specific routines of silc_socket_[read/write]
3856 to lib/silcutil/win32/silcwin32sockconn.c.
3858 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3860 * Added preliminary support for native WIN32 compilation under
3861 cygwin (using the -mno-cygwin option for GCC) to the
3862 ./configure.in.pre. The --with-win32 now prepares the
3863 compilation for native WIN32.
3865 * Rewrote the SILC Scheduler interface in the file
3866 lib/silcutil/silcschedule.h. The scheduler is now context
3867 based and does not have anymore any global static scheduler.
3868 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3869 and created lib/silcutil/win32 directory for WIN32 based
3872 * Added Unix specific network routines to the
3873 lib/silcutil/unix/silcunixnet.c and the old
3874 lib/silcutil/silcnet.c includes now only generic routines.
3876 Added WIN32 specific network routines to the
3877 lib/silcutil/win32/silcwin32net.c.
3879 * Added Unix specific utility functions from the
3880 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3882 * Added WIN32 SILC Scheduler to the file
3883 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3886 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3888 * Do not handle JOIN notify in the server if the target client
3889 is not registered (idata->registered == FALSE). The affected
3890 file is silcd/packet_receive.c.
3892 * Update the nickrec->founder in event_cumode in the Irssi SILC
3893 client. Affected file irssi/src/silc/core/silc-channels.c.
3895 * Fixed the CUMODE_CHANGE notify handling in the server when
3896 server and router are announcing their clients on channels.
3897 Now the mode changes are saved and notified correctly. The
3898 affected file is /silcd/packet_receive.c.
3900 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3901 They really did not replace the cache entry in the ID Cache.
3902 Now they do that. Affected file silcd/idlist.c.
3904 * Fixed the KICK notify handling in the Irssi SILC client to
3905 update the channel records so that the kicked client does not
3906 appear to be on the channel. The affected file is
3907 irssi/src/silc/core/silc-channels.c.
3909 * Always update the conn->current_channel when executing command
3910 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3912 * Fixed the KILL notify handling in Irssi SILC client to remove
3913 the killed client on all channels.
3915 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3917 * Fixed the silc_parse_command_line to remove extra spaces
3918 from the start and end of the arguments. Affected file is
3919 lib/silcutil/silcutil.c.
3921 * Cancel and free any active protocol in the function
3922 silc_server_close_connection. Affected file silcd/server.c.
3924 * Cancel and free any active protocol in the function
3925 silc_client_close_connction. Affected file is
3926 lib/silcclient/client.c.
3928 * Do not execute the KILL command for clients that are in
3929 history (ie. they are not in the network). Affected file is
3932 * Fixed KILL notify handling, client does not crash anymore.
3933 Affected file irssi/src/silc/core/silc-channels.c.
3935 * Reduced the default packet buffer size from 2048 to 1024 in
3936 lib/silccore/silcpacket.c.
3938 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3939 counter to the SKE context that is incresed when the SKE library
3940 performs async operation outside the library. If the outside
3941 process frees the SKE context and FREED status will be set
3942 and the library will detect after the sync operation that the
3943 libary is freed. The affected files are
3944 lib/silcske/silcske[_status].[ch].
3946 * Resolve the client entry information in the function
3947 silc_client_channel_message to assure that NULL pointer is not
3948 passed as client entry to the application. */
3950 * Fixed the task timeout calculation to assure that there is
3951 never negative timeouts. The affected file is
3952 lib/silcutil/silcschedule.c.
3954 * Fixed the channel user mode notification sending in server.
3955 It was sent point-to-point to the router (or to server by router)
3956 but it needs to be destined to a channel. The routines now
3957 supports sending the channel user mode notifys to the channels
3958 when announcing clients and channels. Affected files are
3959 silcd/server.c and silcd/packet_receive.c.
3961 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3962 It did not actually replace the old channel entry in the cache.
3963 Affected file lib/silcclient/client_notify.c.
3965 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3967 * Fixed a possible crash in silc_packet_send_prepare. It now
3968 assures always that there is enough space in the buffer and
3969 at the tail area of the buffer (for MAC).
3971 Fixed the inbound buffer reallocation in silc_packet_read.
3972 It was old code and did not handle the reallocation correctly.
3975 The affected file is lib/silccore/silcpacket.c.
3977 * Fixed buffer overflow in silc_parse_nickname in the file
3978 lib/silcutil/silcutil.c.
3980 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3982 * make install generates new server keys only if there is not
3985 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3987 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3988 Added check that if the NOREPLY is set then we will not send
3989 the away message. This avoids infinite loop of away messages
3990 if both clients are away. The affected file is
3991 lib/silcclient/client_prvmsg.c.
3993 * Fixed client crash if /NICK was given without arguments.
3994 Affected file lib/silcclient/command.c.
3996 * Server does not send the invite list in INVITE command back
3997 to the client if the list was not altered. Added this notion
3998 to the protocol spec as well. Affected file silcd/command.c.
4000 Fixed possible crash in INVITE command by checking the
4001 value of silc_server_get_client_route command.
4003 * Fixed the INVITE notify type handling. The arguments are now
4004 taken in correct order and client does not crash. The affected
4005 file is irssi/src/silc/core/silc-channels.c.
4007 Removed the "Inviting xxx to channel" message from the
4008 client library away and let the application handle it.
4009 Affected file lib/silcclient/command.c. Added that message
4010 to Irssi SILC client's message formats.
4012 * Fixed CMODE command crash in client. It now checks the
4013 amount of arguments correctly and does not crash. The affected
4014 file is lib/silcclient/command.c.
4016 * Do not create new channel automatically in silc_channels_join
4017 but check whether the channel by that name already exists.
4018 Affected file irssi/silc/core/silc-channels.c.
4020 * Do not send the SERVER_SIGNOFF to router if the disconnected
4021 entity was the router. Affected file silcd/server.c.
4023 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4024 SILC client as it was missing from there.
4026 Added the handling of the KICK notify to the Irssi SILC client
4027 as it was missing. Added "you have been kicked" message to
4028 Irssi SILC client's message modules formats.
4030 Added the handing of the KILL notify to the Irssi SILC client
4031 as it was missing. Added the kill message module formats
4034 The affected file is irssi/src/silc/core/silc-channels.c.
4036 * The router did not save the channel mode the server announced.
4037 Affected file silcd/packet_receive.c.
4039 * Fixed a possible crash in INFO command in server. If the
4040 server did not provide the server info it crashed. Affected
4041 file silcd/command.c.
4043 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4045 * Fixed the GETKEY command in the server to check also the
4046 global list. Otherwise the GETKEY would not work correctly
4047 in normal SILC server. Affected file silcd/command.c.
4049 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4051 * Fixed GETKEY crash, it crashed if the command did not succseed.
4053 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4055 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4056 is now real and not just an macro interface to GMP.
4058 Removed the entire GMP from the source tree and imported new
4059 NSS MPI library instead. Reason for removing GMP is that it is
4060 extremely large and compiles extremely slow. The NSS MPI
4061 is only a few files and compiles in less than 10 seconds.
4062 The speed is also about the same as GMP. The MPI is imported
4063 to lib/silcmath/mpi.
4065 If the system has GMP installed we will still use the GMP.
4066 If it is not then the NSS MPI will be compiled.
4068 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4070 * Merged a long nickname (127 characters long) crash bugfix from
4071 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4073 * Merged a freed memory reference bugfix from Irssi CVS tree.
4074 Affected file irssi/src/core/commands.c.
4076 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4078 * Added the server's public key sving and verification to the
4079 server when performing the SKE. This was missing and the
4080 remote server's (or router's) public key was accepted without
4081 checking whether we have it previously or trust it at all.
4082 Affected file silcd/protocol.c.
4084 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4086 * Check in the silc_server_timeout_remote if protocol is active
4087 and make sure that the protocol's final callback is called so
4088 that all memory if freed. Affected file silcd/server.c.
4090 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4092 * silc_server_whois_send_reply crashed the server if the nickname
4093 was 127 characters long. Affected file silcd/command.c.
4095 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4097 * Added sanity check to the silc_server_new_client. If the hostname
4098 is provided inside username then check that the provided hostname
4099 really is the same as the resolved one. If the hostname was not
4100 resolved then check it from the public key. Affected file is
4101 silcd/packet_receive.c.
4103 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4104 if the server disconnected us and the connection is not valid
4105 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4107 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4108 the library to the lib/silcutil/silcutil.[ch].
4110 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4112 * Close log file after open. Affected file
4113 lib/silcutil/silclog.c.
4115 * Check whether sock == NULL in silc_client_send_packet and return
4116 if it is. Affected file lib/silcclient/silcclient.c.
4118 * Check rec->entry == NULL in the Irssi SILC Client before
4119 sending the channel message. Affecte file is
4120 irssi/src/silc/core/silc-servers.c.
4122 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4124 * Merged a splitted window bugfix from Irssi CVS tree. The
4125 affected file is irssi/src/fe-text/textbuffer-view.c.
4127 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4128 It did not print nickname.
4130 * Improved the distributions system a bit.
4132 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4134 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4135 irssi/src/fe-text/gui-window.c.
4137 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4138 to in-active server. The affected file is
4139 irssi/src/silc/core/client_ops.c.
4141 * Resolve the client in USERS command reply if the entry does
4142 not have username resolved. The affected file is
4143 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4144 command to WHOIS command to really resolve stuff. The USERS
4145 is not used any more in any critical section so WHOIS can
4146 be used even though it might be slower than IDENTIFY.
4148 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4151 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Changed the protocol API a bit more consistent in the
4154 lib/silccore/silcprotocol.[ch].
4156 * Changed the following headers to ROBODoc format:
4158 lib/silccore/silcpayload.h
4159 lib/silccore/silcprotocol.h
4160 lib/silccore/silcsockconn.h
4162 All core library headers are now formatted.
4164 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Fixed a bug in Irssi SILC client; do not show that you are
4167 server/router operator if you really are not. Affected file is
4168 irssi/src/silc/core/client_ops.c.
4170 * Renamed silc_command_free_payload to silc_command_payload_free.
4171 Affected file lib/silccore/silccommand.h
4173 * Added silcmath.h to include the prototoypes of various routines
4174 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4177 * Changed the following headers to ROBODoc format:
4179 lib/silccore/silcchannel.h
4180 lib/silccore/silccommand.h
4181 lib/silccore/silcid.h
4182 lib/silccore/silcidcache.h
4183 lib/silccore/silcmode.h
4184 lib/silccore/silcnotify.h
4185 lib/silccore/silcpacket.h
4186 lib/silcmath/silcmath.h
4188 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4190 * Added checking to the server code not to start the server if
4191 ciphers and stuff are not configured properly. Affected files
4192 silcd/serverconfig.[h] and silcd/server.c.
4194 * Changed the layout of the header files of the public interfaces
4195 in the SILC libraries. The new layout supports ROBODoc
4196 documentation tool (and some others) so that it is easy to create
4197 a library reference manual. All the other headers and source
4198 code must still follow the CodingStyle document. Also source
4199 code must not include these ROBODoc stuffs, only the headers.
4200 Furthermore, all public interface headers must now be named
4201 by using `silc' prefix, example: silcapi.h, silccipher.h.
4202 Some files were renamed due to this. All the other headers
4203 must not be used as public interfaces. I will update the
4204 CodingStyle document later. Changed following headers, so far:
4206 lib/silcclient/silcapi.h
4207 lib/silccore/silcauth.h
4208 lib/silccore/silcprivate.h
4209 lib/silccrypt/silcdh.h
4211 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4215 * Removed silc_client_packet_send_flush from the client library
4216 as it is not needed. Affected file lib/silcclient/client.[ch].
4218 * Added printing of message of unresolved authentication method
4219 to the Irssi SILC client. Added it to the module formats.
4220 Removed the same message from the client library.
4222 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4224 * Added new distribution feature, DISTLABEL. Every distribution
4225 can define own preprocessor label that can be used in the
4226 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4227 file distributions, acconfig.h.pre and prepare.
4229 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Added Makefile.defines_int to include the actual definitions
4232 for Makefile.defines.in. Tested the new distribution system,
4233 created distributions and tested installation.
4235 * Added AWAY message printing to the Irssi SILC client. Added
4236 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4238 * Added SCONNECT command to call the SILC's CONNECT command.
4239 Cannot use CONNECT directly since Irssi uses that internally.
4240 Affected file irssi/src/silc/core/silc-servers.c.
4242 Added ACTION local command. It is same as ME command but takes
4243 the channel as mandatory argument.
4245 Rewrote some of the Irssi's help files to suite for SILC
4248 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4250 * Added Makefile.defines[.in] that should for now on be included
4251 in all Makefile.am file in the source tree. That file includes
4252 all common compilation definitions for SILC source tree.
4254 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Minor changes to the ./prepare script to change the package
4257 name according the distribution name to the configure.in.
4259 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4261 * Created new distribution system. Added file `distributions'
4262 that defines all the distributions that can be created out of
4263 the SILC source tree. The ./prepare script now reads that
4264 file to determine how to prepare the distributions. The
4265 first argument to the ./prepare is the name of the distribution
4266 and second is the version of the distribution. If given
4267 without arguments it creates the default (toolkit) distribution
4268 with the default version (defined in ./prepare).
4270 All Makefile.am files that are subject to the distributions
4271 are now named as Makefile.am.pre. These are ./Makefile.am
4272 and lib/Makefile.am. Others may be changed later.
4274 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4276 * Added invite list, ban list, some key management and connection
4277 error message printing to module formats in the Irssi SILC client.
4279 * Added new silc_client_set_away_message to set the away message
4280 that is back to the person who sent private message. The
4281 affected file lib/silcclient/silcapi.h and the
4282 lib/silcclient/client_prvmsg.c.
4284 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4286 * Fixed the private message sending in the Irssi SILC client,
4287 added local command KEY to the Irssi SILC client.
4289 Added key management and key agreement message formats to the
4290 irssi/src/fe-common/silc/module-formats.[ch].
4292 Added USERS (alias WHO) printing, server/router operator
4293 indication and LIST command printing to the module formats.
4295 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4297 * Fixed channel joining notify handling, cumode notify handling
4298 from Irssi SILC client.
4300 * Added SILC specific module-formats to the Irssi SILC client so
4301 that SILC specific message hilighting, colors etc is possible.
4302 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4304 Added channel mode, channel user mode, actions, notices,
4305 whois and whowas printing to the the module-formats.c.
4307 * Fixed a bug in channel deletion in the server. The channel
4308 is not left to the cache even if the channel founder auth mode
4309 is set when there are no users anymore on the channel. Affected
4310 file silcd/server.c.
4312 * The silc_net_localhost now resolves the entire hostname including
4313 the domain name. Affected file lib/silcutil/silcnet.c.
4315 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Changed the ask_passphrase client operation to be ascynchronous.
4318 It has now a completion callback and a context that the
4319 application must call after it has got the passphrase from
4320 the user. Affected files lib/silcclient/silcapi.h,
4321 lib/silcclient/protocol.c, lib/silcclient/command.c and
4324 Added SilcAskPassphrase callback that the application calls
4325 to deliver the passphrase to the library.
4327 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4328 The public key verification and especially a certificate
4329 verification is asynchronous procedure.
4331 Added new SILC_SKE_STATUS_PENDING status to indicate the
4332 request is pending and a callback will be called to finalize
4335 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4336 indicate that remote end did not send its public key (or
4337 certificate), even though we require it. Added check for this
4338 condition in the SKE. This was a security bug, now fixed.
4340 Defined new SilcSKEVerifyCbCompletion callback that is called
4341 when the verification process is completed.
4343 The affected files lib/silcske/silcske_status.h and
4344 lib/silcske/silcske.[ch].
4346 * Changed the verify_public_key client operation to be async
4347 as well. Defined SilcVerifyPublicKey callback that is used to
4348 indicate the success of the public key verification process.
4350 Changed the server and client to use the new async client
4353 * Changed the Irssi SILC client's internal scheduler to be called
4354 twice as many times as it used to be. As a result the client
4355 should be a bit faster now. Affected file is
4356 irssi/src/silc/core/silc-core.c.
4358 * Added support to Irssi SILC client of asynchronous public key
4359 verification and passphrase inquiry. Affected file is
4360 irssi/src/silc/core/silc-core.c.
4362 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4364 * Do not say "You have left channel %s" in client library.
4365 Moved it to the application. Affected files are
4366 lib/silcclient/command.c and silc/client_ops.c.
4368 * Fixed silc_client_get_clients. Command context was not
4369 duplicated and was freed memory in the callback. Affected
4370 file lib/silcclient/idlist.c.
4372 * Do not say "you are now talking..." on JOIN command in the
4373 client library. The appliation must handle it.
4375 * Do not say ".. changed topic to" in command reply in the
4376 client libary. The application must handle it.
4378 * Fixed TOPIC command sending in the client library.
4380 * Fixed a memory leak in silc_client_command_free in the file
4381 lib/silcclient/command.c.
4383 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Imported a modified version of Irssi client to the source tree.
4386 The Irssi will be used to create a new client called
4387 Irssi SILC. Imported to irssi/.
4389 Added silc_core_init_finish function to the Irssi. Affected
4390 file irssi/configure.in.
4392 A lot changes in the Makefile.ams around the irssi tree.
4394 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4396 * Do not rehash if the new size is same as the old size of the
4397 hash table, in the silc_hash_table_rehash*. The affected file
4398 lib/silcutil/silchashtable.c.
4400 * Replaced hash_table_del_by_context calls from the server
4401 (when channel->user_list and client->channels) to the
4402 hash_table_del as it is sufficient and faster.
4404 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4406 * Added silc_hash_table_list, silc_hash_table_get and the
4407 SilcHashTableList structure to provide an alternative way to
4408 traverse the hash table. The affected files are
4409 lib/silcutil/silchashtable.[ch].
4411 * Changed the server's idlist routines to use the hash table
4412 routines to optimize the code.
4414 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4416 * Replaced the client entry's `channel' list and channel entry's
4417 `user_list' list to hash tables for optimized lookup. Changed
4418 the code to use the hash table interface around the code.
4419 Affected file lib/silcd/idlist.[ch].
4421 * Added `auto_rehash' boolean argument to the function
4422 silc_hash_table_alloc to indicate whether the hash table should
4423 auto-rehash when it thinks is appropriate time. It will
4424 increase the hash table size if the there is twice as much
4425 entries in the table than the size of the table, and will
4426 decrease the size if there are twice as less entries than
4427 the size of the table.
4429 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4431 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4433 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4435 * silc_idcache_purge_by_context deletes the entry now by context
4436 as it is supposed to do. Affected file lib/silccore/idcache.c.
4438 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4439 client is not anymore valid (WHOWAS givens the info) and not
4440 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4442 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Removed the `data' and `data_len' arguments from the ID Cache
4445 interfaces and added `name' argument. ID Cache does not handle
4446 anymore the binary data only a names associated with given ID.
4448 * When hashing a Client ID with silc_hash_id the entire ID is
4449 not hashed anymore, instead only the hash of the Client ID is
4450 hashed. This way we can access the Client ID from the cache
4451 with Client ID but with the hash of the ID (which is a hash of
4452 the nickname) as well without any difference in performance.
4454 Added also silc_idcache_find_by_id_one_ext to do one on one
4455 searching when we have the actual ID. Added also function
4456 silc_hash_client_id_compare. The affected files are
4457 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4459 * When hashing the name associated with a ID it is always done
4460 in lowercase. This way we can access the cache without worrying
4461 about case-sensitivity, even though, for example nicknames are
4464 * Fixed a bug in server with channel message sending. It put
4465 wrong ID type as destination ID. The affected file
4466 silcd/packet_send.c.
4468 * silc_idcache_del_by_context now deletes from all hash tables
4469 by context. Affected file lib/silccore/idcache.c.
4471 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Changed the client library to use the new ID Cache interface.
4474 Changes around the source tree.
4476 * Added silc_hash_table_rehash_ext to rehash with specific
4477 hash function. Affected file lib/silcutil/silchashtable.[ch].
4479 * Added silc_hash_string_compare to compare two strings in the
4480 hash table. Affected file lib/silcutil/silcutil.[ch].
4482 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4484 * Added new function silc_idcache_del_by_context into the
4485 lib/silccore/idcache.[ch].
4487 * Changed the server's ID list routines to use the new ID Cache
4488 interface. Changes around the source tree.
4490 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4492 * Added silc_hash_table_del[_by_context]_ext functions in to the
4493 lib/silcutil/silchashtable.[ch].
4495 Removed silc_hash_table_find_all* routines and added new
4496 silc_hash_table_find_foreach to replace them.
4498 Added silc_hash_table_replace_ext function as extended
4499 replacing function. Separated the simple hash table interface
4500 from the extended hash table interface in the file
4501 lib/silcutil/silchashtable.h.
4503 * Fixed minor bugs and changed it to use some of the new
4504 hash table functions in lib/silccore/idcache.c
4506 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4508 * Added new function silc_hash_table_find_all to return all keys
4509 in the hash table by the specified key. As the hash table is
4510 collision resistant it also makes it possible to have several
4511 duplicate keys in the hash table. This function may be used to
4512 find all of the keys from the hash.
4514 Added user_context arguments to the SilcHashFunction,
4515 SilcHashCompare and SilcHashDestructor to deliver user specified
4518 Added new fuctions silc_hash_table_find[_all]_ext to do
4519 extended lookup with specified hash and compare functions and
4520 specified user contexts.
4522 Added new function silc_hash_table_add_ext to add the key
4523 with specified hash function and user context.
4525 Added new function silc_hash_table_foreach to traverse all
4526 entrys in the hash table. Added SilcHashForeach callback
4529 Added new function silc_hash_table_del_by_context to delete
4530 the entry only if the context associated with the key matches.
4532 Affected files are lib/silcutil/silchashtable.[ch].
4534 * Removed silc_hash_[server/client/channel]_id and added just
4535 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4536 silc_hash_id_compare to compare two ID's using as the hash table
4537 comparison function. Added also silc_hash_data to hash
4538 binary data and silc_hash_data_compare to compare it.
4540 * Removed silc_idlist_find_client_by_hash as it is not needed
4541 anymore. Affected file silcd/idlist.[ch].
4543 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4544 to use internally the SilcHashTable. The new ID Cache is a lot
4545 faster than the old one. Some of the ID Cache interface was also
4546 rewritten and obsolete and stupid functions were removed.
4548 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4550 * Added entry_count field to the SilcHashTable to keep the number
4551 of the entries in the table. Implemented the function
4552 silc_hash_table_rehash. Added new function
4553 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4555 Fixed a minor bug in silc_hash_table_free.
4557 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4558 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4559 into the lib/silcutil/silcutil.[ch].
4561 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4563 * Implemented a collision resistant hash table into the
4564 lib/silcutil/silchashtable[ch]. See the header and the source
4565 for the SilcHashTable API.
4567 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4569 * Merged dotconf version 1.0.2 into lib/dotconf.
4571 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4573 * Do not compile anything in lib/silcsim/* if the SIM support
4574 is not enabled. The tree should now compile without problems
4577 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4579 * Compiled the SILC under cygwin. Compiled and tested briefly
4580 without problems. More tests needed. The SIMs didn't compile
4583 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4585 * Fixed possible crash in silc_get_username in the
4586 lib/silcutil/silcutil.c.
4588 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Fixed a va_arg in silc/client_ops.c.
4592 * Oops, RC5 routines were named AES and caused some problems
4593 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4595 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Added new SilcIDIP structure into the lib/silccore/id.h and
4598 replaced the old `ip' fields from all SILC ID's to that type.
4599 This is a step towards IPv6 support.
4601 The silc_id_get_len takes now the ID as an extra argument.
4602 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4603 both IPv4 and IPv6 based ID's.
4605 The affected files are lib/silccore/id.[ch] and other files
4606 around the tree using these routines.
4608 * Removed the ID length arguments in server from various
4609 silc_server_send_notify_* routines -> they are not needed
4612 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Fixed memory leak in silc_encode_pem_file in the file
4615 lib/silcutil/silcutil.c.
4617 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4619 * Check minor version as well in the SKE. Affected files are
4620 silcd/protocol.c and lib/silcclient/protocol.c.
4622 * Added --identifier option to the server so that an identifier
4623 can be when creating the public key for the server. Affected
4624 file is silcd/silcd.c.
4626 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4627 lib/silccrypt/silcpkcs.c.
4629 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Register default ciphers and stuff when using -C option with
4632 the server. Affected file sildc/silcd.c.
4634 * Put back the servers public key filename format, it is better
4635 than the new one. For now, the client keys are saved with the
4636 new filename format. The affected file silc/client_ops.c.
4638 * Implemented the Cipher API for the rest of the ciphers that
4639 did not implement it or implemented it the wrong way.
4641 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4643 * Register default ciphers and stuff when using the -S option
4644 in the client. Affected file silc/silc.c. Same also when
4645 creating new key pair with -C option.
4647 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4649 * Fixed the silc_verify_public_key client operation function to
4650 save the public keys differently. The fingerprint is now
4651 used as filename and not the hostname. This way also the
4652 client keys are saved uniquely and not with hostnames. The
4653 affected file is silc/client_ops.c.
4655 * Trimmed the silc_hash_fingerprint function to remove extra
4656 whitespaces from the end of the fingerprint. The affected
4657 file is lib/silccrypt/silchash.c.
4661 * Added silc_cipher_register_default function to register all
4662 default ciphers. It can be used when configuration files
4663 does not exist and the application does not want any specific
4664 ciphers in any specific order.
4666 The SilcDList is now used as silc_cipher_list dynamically
4667 allocated cipher list. Removed the static list all together
4668 and now all ciphers must be allocated to the dynamic list.
4669 The silc_cipher_alloc routine was changed to check only the
4672 All silc_cipher_* routines that used to return int returns
4675 The affected files lib/silccrypt/silccrypt.[ch].
4677 * The same thing was done to silc_hash_* as for silc_cipher_*
4678 routines. Affected files lib/silccrypt/silchash.[ch].
4680 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4681 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4682 Added also silc_pkcs_[un]register[_default] functions.
4683 Removed the data_context from the PKCS API.
4685 * Added silc_hmac_register_default function to register default
4686 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4687 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4688 to unregister all hmacs at once.
4690 * Register the default ciphers, hash functions, PKCSs and HMACs
4691 if client's configuration file does not exist. The affected
4694 * The client did not load the hash functions from the SIM
4695 modules at all. Added support for this. Affected file is
4696 silc/clientconfig.c.
4698 * When decoding public key with silc_pkcs_public_key_decode, check
4699 the supported algorithm only if PKCS are registered. Affected
4700 file lib/silccrypt/silcpkcs.c. The same was done with the
4701 silc_pkcs_private_key_decode.
4703 * Fixed the SILC List routines to keep the list always in order.
4704 It used to change the list's order when traversing the list but
4705 not it preserves the order. Affected file lib/trq/silclist.h.
4707 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4709 * Added the client library to use the SilcSocketConnection's
4710 reference counter (by silc_socket_dup) to prevent the bug that
4711 the socket object may be freed underneath async operation.
4713 * The name resolv library checking fixes in the configure.in.pre.
4716 * Created new version of the protocol drafts for future
4717 development. The -03 drafts are the ones that will be changed
4718 in the trunk now and the -02 will remain as they are.
4720 * Send list of CUMODE notifys to the router when announcing
4721 the channel users to the router. Affected file silcd/server.c.
4722 If the router receiving channel founder CUMODE for a channel
4723 that already has channel founder it will send CUMODE notify
4724 to the sender to remove the channel founder rights from the
4725 announced client. Affected file silcd/packet_receive.c.
4727 * The CUMODE notify may now use Server ID as well as the entity
4728 who changes the mode. Updated protocool specs.
4730 * Updated INSTALL and README files.
4732 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4734 * New web pages in the http://silc.pspt.fi. The pages was
4739 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4741 * Implemented the [DenyConnectin] config section in the server.
4742 Added silc_server_config_denied_conn to check whether incoming
4743 connection is denied. Affected file silcd/serverconfig.[ch].
4745 * Do not check the ports when checking the incoming configuration
4746 data if the port is 0, meaning any. Affected file is
4747 silcd/serverconfig.c.
4749 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4751 * Fixed buffer overflow in silc_string_compare in the file
4752 lib/silcutil/silcutil.c.
4754 * Fixed double free in silc_server_command_leave in the file
4757 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4759 * Fixed the version checking in the server. Affected file is
4762 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4764 * Fixed the configuration data fetching when accepting new
4765 connections in the server. Affected file silcd/server.c.
4767 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4769 * Added `sender_entry' argument to the function
4770 silc_server_packet_relay_to_channel so that we can check
4771 whether some destination actually belongs to the same route
4772 the sender belongs (ie, we must not resend the packet to the
4773 sender). Affected file silcd/packet_send.[ch].
4775 * Added `servername' field to the SilcClientEntry in the server
4776 to hold the name of the server where client is from. Affected
4777 file is silcd/idlist.h.
4779 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4781 * Moved the channel message encrypting in the router betwen
4782 router connections from silc_server_channel_message to the
4783 silc_server_packet_relay_to_channel since we want to check
4784 whether we have anybody channel before encrypting anything.
4785 Affected files silcd/packet_[receive/send].c.
4787 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4789 * Fixed the [AdminConnection] server config section to support
4790 multiple entries. Affected file silcd/serverconfig.c.
4792 * Added support into the server to check the validity of the
4793 incoming connection before executing any KE or authentication
4796 * The connection configuration is now saved to the KE and
4797 connection auth protocol contexts and not fetched anymore in
4798 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4800 * The local hosts listenning address and port is also resolved
4801 now when starting the server. We want to have the socket object
4802 to include the real address and port for the listener. Added
4803 new function silc_net_check_local_by_sock into the files
4804 lib/silcutil/silcnet.[ch].
4806 * Fixed a broadcast bug in server -> do not broadcast if we
4809 * Fixed a routing bug. Do not route broadcast packets ever.
4810 Broadcast packets must be processed always and not routed since
4811 they may be destined to some other host than yourself and thus
4812 would get routed without no good reason. Affected file is
4815 * Added function silc_server_config_is_primary_route to check
4816 whether primary router connection has been configured (a router
4817 configuration that we are initiating). If there is not, we
4818 will assume that there is only two routers in the SILC network
4819 and we will use the incoming router connection as our primary
4820 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4822 * Changed the order of the broadcasting. Broadcast _after_ the
4823 packet has been processed not before. Affected file is
4826 * Fixed a [ClientConnection] parsing bug. The port was never
4827 parsed correctly thus resulting to port 0. Affected file
4828 silcd/serverconfig.c.
4830 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4831 argument and did not set the broadcast packet flag. Affected
4832 file silcd/packet_send.c. Fixed same bug in the function
4833 silc_server_send_notify as well.
4835 * If we receive NEW_ID packet for our own ID in the server, ignore
4838 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4842 * Removed the nickname from the Private Message Payload.
4843 Updated the code and the protocol specs.
4845 * Updated protocol specs for submitting to the IETF.
4847 * Tweaked the Random Number Generator a bit. Affected file
4848 lib/silccrypt/silcrng.c. Exported a new function
4849 silc_rng_[global]_add_noise which can be used to add more
4852 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4854 * Do not parse packets with different timeout when protocol
4855 is active -> may cause problem with rekey. Affected file
4858 * When server receives signoff notify it must not create
4859 new channel key if the client is on any channels since the
4860 sender of the signoff notify will create it.
4862 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Added printing of error messages during SKE protocol from the
4865 failure packet sent by server during SKE. Affected file
4868 * Removed the client's failure_callback handling with timeout
4869 and handle it immediately when received.
4871 * The SKE library returned wrong type in SUCCESS and FAILURE
4872 packets. They must be 32 bit MSB not 16 bit MSB.
4874 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4876 * Ok, rewrote the logic of the re-key and now it seems to work.
4877 I tested it on high traffic with frequent re-keys without
4878 problems. Added hmac_receive (and renamed hmac to hmac_send)
4879 in SilcClientConnection in lib/silcclient/client.h and
4880 in SilcIDListData in silcd/idlist.h. Also, removed the
4881 SilcPacketParserContext's cipher and hmac fields as they are
4882 not needed anymore and actually caused some problems when
4883 the ciphers and hmac's changed underneath the packet parser.
4885 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4887 * If re-key protocol is active then process the incoming packets
4888 synchronously since we must assure that icoming packets encrypted
4889 with the old key is processed before the new keys is set to
4890 use. This is true other packets than for REKEY packets.
4891 Affected file silcd/server.c. The same was done to client library
4892 as well, affected file lib/silcclient/client.c.
4894 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4896 * Fixed bug in client and server to accept the force send if
4897 the packet is send from silc_[server/client]_packet_process
4898 function. Otherwise the packets are never delivered, oops.
4900 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4902 * Disable force sending of packets when REKEY protocol is active.
4903 We must assure that no packet is sent directly when rekey is
4904 performed. All packets must be sent through packet queue.
4905 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4906 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4907 function is silc_[server/client]_packet_send_real to check
4910 * Replaced the SIM paths from example config files to
4911 /usr/local/modules. Also, make install creates now
4912 /usr/local/silc/logs directory to hold all the SILC server
4915 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Made the configure.in.pre work on Solaris. Patch by salo.
4919 * Made all ciphers compatible with non-x86 machines. Defined
4920 CBC mode macros into lib/silccrypt/ciphers_def.h.
4922 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4924 * Fixed the make install.
4926 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * When MAC computation fails the silc_packet_decrypt returned 0
4929 even though it was supposed to return -1. Fixed this. The
4930 affected file is lib/silccore/silcpacket.c.
4932 * Do not replace the config files in /etc/silc (in make install)
4933 if they already exist. Affected file ./Makefile.am.
4935 * Do not send re-key packets immediately but through packet queue.
4936 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4938 * Changed silc_net_check_host_by_sock to return FALSE if the
4939 IP/DNS could not be resolved. Though, it returns the IP address
4940 now even if it could not resolve it (but returns also FALSE).
4941 Affected file lib/silcutil/silcnet.[ch].
4943 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4945 * Added silc_pkcs_decode_identifier to decode the public key's
4946 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4947 Added also silc_pkcs_free_identifier. Added also new context
4948 SilcPublicKeyIdentifier.
4950 * Added -S option to the silc client. It is used to dump the
4951 contents of the specified public key file.
4953 * Changed the PKCS api to return the public key length when
4954 setting the public key.
4956 * Fixed a fatal bug in the public and private key file loading.
4957 Affected file lib/silccrypt/silcpkcs.c.
4959 * Execute the packet parsing for client with zero (0) timeout
4960 if the protocol is active. Affected file silcd/server.c.
4962 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Made the key generation options to the silcd program. Added
4965 -C option, equivalent to client's option.
4967 * Added new [ServerKeys] config section to the server. It
4968 configures the server's public and private key.
4970 * Defined generic Public Key Payload into the protocol
4971 specification to send specific type of public keys and
4974 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4975 public key or certificate.
4977 * Implemented the GETKEY command to the server and to the
4978 client library and on user interface.
4980 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4982 * Made preliminary `make install' work.
4984 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Added SilcServerRekey context into silcd/idlist.h.
4988 * Added the PFS support as defined in the specification to the
4989 SKE protocol. Affected files lib/silcske/*.c.
4991 * Added `ske_group' field to the SilcServerRekey context to hold
4992 the number of the SKE group that is used with PFS in re-key.
4993 Affected file silcd/idlist.h.
4995 * Added PFS re-key support to the server. Affected file is
4998 * Added silc_protocol_cancel to cancel execution of the next
4999 state of the protocol. Affected file is
5000 lib/silccore/silcprotocol.[ch].
5002 * Added the re-key support with and without PFS to the client
5003 library. Re-key is performed once in an hour, by default.
5005 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5006 Added silc_client_rekey_callback and silc_client_rekey_final.
5007 Affected files are lib/silcclient/protocol.[ch] and
5008 lib/silcclient/client.[ch].
5010 * Removed the `hmac_key' and `hmac_key_len' fields from the
5011 SilcClientConnection structure; not needed. Affected file is
5012 lib/silcclient/client.h.
5016 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5018 * Do not ask whether user wants to use the negotiated private key
5019 for private messages, just use it. Affected file is
5020 silc/local_command.c.
5022 * Added `send_enc_key' and `enc_key_len' fields to the
5023 SilcIDListData structure since they are needed in the re-key
5024 phase. Affected file is silcd/idlist.[ch].
5026 * Implemented the simple re-key protocol into the server.
5027 Affected files silcd/server.c and silcd/protocol.[ch]. The
5028 re-key will be performed once in an hour, by default.
5030 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5031 Added silc_server_rekey, silc_server_rekey_callback and
5032 silc_server_rekey_final.
5034 * Removed Tunneled flag from the protocol. Updated the code
5035 and the specifications.
5037 * Adde `pfs' field to the SilcIDListData to indicate whether
5038 the PFS is to be performed in the re-key. Affected file is
5041 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5044 int64 of at least the xintXX size. If void * is less that 4
5045 bytes uint32 * will be used. Defined bool as boolean.
5047 * Changed _ALL_ unsigned long and unsigned int to uint32,
5048 unsgined short to uint16 in the source tree.
5050 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5051 not handle clients that has entry->data.registered == FALSE.
5052 They are not in the network anymore. Affected file is
5055 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5057 * Implemented the sending of the SERVER_SIGNOFF notify in the
5058 server. Affected file is silcd/server.c.
5060 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5061 Added also silc_notify_payload_encode_args into the
5062 lib/silccore/silcnotify.[ch].
5064 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5065 Affected file silcd/packet_receive.c.
5067 * Implemented the SERVER_SIGNOFF notify handling in the client
5068 library. Affected file lib/silcclient/client_notify.c. Also,
5069 implemnted the printing of the SERVER_SIGNOFF info to the
5070 application. Affected file silc/client_ops.c.
5072 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5073 if the deleting was successful. Affected file silcd/idlist.[ch].
5075 * Added support for public key authentication in the connection
5076 authentication protocol in the client library. Affected file
5077 lib/silcclient/protocol.c.
5079 * Changed the server's silc_idlist_get_clients_by_* interface
5080 to support already allocated array so that new entries may be
5081 added to pre-allocated array. Affected file silcd/idlist.[ch].
5082 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5083 and command replies.
5085 * All command reply functions in the server now calls the
5086 pending command callback even if error occured. This way the
5087 error will be delivered to the client as well. Affected files
5088 silcd/command.c and silcd/command_reply.c.
5090 * Fixed INFO command to return local server's info if no server
5091 was provided. Affected file lib/silcclient/command.c.
5093 * Removed RESTART command for good. Updated the code and the
5096 * Rewrote parts of the task system. It is a bit simpler now.
5097 Removed unsued task priorities. The affected files are
5098 lib/silcutil/silctask.[ch].
5100 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5102 * Moved the USERS printing from the library to the application.
5103 Affected files lib/silcclient/command.c and silc/client_ops.c.
5105 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Added channel key re-key support. The re-key is perfomed
5110 only by the router and is done once in an hour. Added `rekey'
5111 field to the SilcChannelEntry in the server. Affected files
5112 silcd/server.c and silcd/idlist.h.
5114 * Added silc_task_unregister_by_context into the file
5115 lib/silcutil/silctask.[ch].
5117 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5119 * Added SILC_UMODE_GONE mode to indicate when the client is not
5120 present in the SILC network. Added also support to the local
5121 command AWAY that will set this mode. Added support of showing
5122 "xxx is gone" in WHOIS command. The USERS command shows the
5123 gone status as well.
5125 * Fixed setting server and router operator privileges in the
5126 server's UMODE command. Affected file silcd/command.c.
5128 * Merged the SKE KE1 and KE2 payloads into one payload. The
5129 new KE payload is equivalent to the old KE2 payload.
5131 Cleaned up the SKE Start Payload parsing. It now uses the
5132 simple buffer unformatting to do the parsing. A lot faster
5135 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5136 to the SKE that is used to indicate whether both of the SKE
5137 parties should perform authentication. By default only the
5138 responder performs authentication. By setting this flag also
5139 the initiator must do authentication. By default it is unset
5140 since in normal SKE case, client to server connection, only
5141 the responder should do authentication. When doing SKE between
5142 two clients both should perform authentication. Updated the
5143 code and the protocol specs.
5145 * A little fix to IDENTIFY command in the server. Search the
5146 client first by hash not nickname. Affected file is
5149 * Fixed the silc_client_close_connection to support closing
5150 the client to client connections wihtout deleting too much
5151 data. Affected file lib/silcclient/client.c.
5153 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5154 are received if protocol used to be active but is not anymore
5155 the application would crash due to NULL pointer dereference.
5156 Affected files silcd/server.c and lib/silcclient/client.c.
5158 * Added `hash' field to the SilcClientConnection to include
5159 the hash function negotiated in the SKE protocol.
5161 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5162 to set the channel founder authentication data. A client can
5163 claim the founder rights later by providing the authentication
5164 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5165 This way the channel founder can regain the channel founder
5166 privileges even it is left the channel. This works only on
5167 local server and the client must be connected to the same
5168 server to be able to regain the founder rights. Updated the
5169 protocol specs accordingly.
5171 Added support to the CMODE command in the client to set the
5172 founder auth data. Read the README to see how to set it.
5174 Added support to the CUMODE command to claim the founder
5175 rights. Read the README to see how to do it.
5177 Added support for the founder authentication to the Channel
5178 Entry in the server. Affected file silcd/idlist.h.
5180 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5181 server's CMODE command. Affected file silcd/command.c.
5183 * Added the following new functions into lib/silccore/silcauth.[ch]:
5184 silc_auth_get_method and silc_auth_get_data.
5186 * The server now saves the remote hosts public key to the
5187 SilcIDListData pointer. Affected file silcd/protocol.c.
5189 * The normal server now does not remove the channel entry from
5190 the cache if the founder authentication data is set. It used
5191 to remove it if the founder was the last one on the channel on
5192 the server and left the channel. The auth data is saved and
5193 if the channel is re-joined later the old entry is used with
5194 the old auth data. Affected files silcd/command_reply.c and
5197 * Removed the `pkcs' field from the SilcIDListData structure
5198 in the server; it is not used. Affected file silcd/idlist.h.
5200 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5202 * Fixed packet processing on slow links. Partial packets were
5203 never re-processed because the incoming data buffer was cleared
5204 by the application. Application must not directly clear the
5205 sock->inbuf, the packet processing routines handle it. Fixed
5206 this in client library and in server.
5208 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5210 * Fixed the WHOIS and IDENTIFY send reply function to really
5211 check whether to send list or just one entry. Affected file
5214 * Cleaned up the LEAVE command's channel key distribution. The
5215 affected file silcd/command.c.
5217 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5218 can enforce the channel mode as well. In that case the ID
5219 includes the ID of the server. The code now enforces the
5220 mode change if the router have different mode than the server.
5222 * The notify client operation with CMODE_CHANGE notify can now
5223 return NULL client_entry pointer if the CMODE was not changed
5224 by client. Application must check for this.
5226 * Added <Server ID> argument to INFO command to support server
5227 info fetching by Server ID.
5229 * Added silc_server_announce_get_channel_users to get assembled
5230 packets of channel users of the specified channel. Affected
5231 file silcd/server.[ch].
5233 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5234 was freed underneath the ID Cache.
5236 * Re-announce clients when the server received CHANNEL_CHANGE
5237 notify from the router. Affected file silcd/packet_send.c.
5239 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5241 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5242 crashed since it did not handle the fact that there is no cipher
5243 called "3" and didn't check the error condition. Now fixed.
5245 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5246 flag. It can be used to send message requests.
5248 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5250 * Implemented the RESTART command in the client.
5252 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5253 notice type messages. Added notice printing to the user
5256 * The channel keys are not re-generated if the channel's mode
5257 is PRIVKEY, ie private key on the channel exists. Affected
5258 files silcd/server.c and silcd/command.c.
5260 * Fixed a little bug in channel message delivery when channel
5261 private keys are set in the server. Affected file is
5262 silcd/packet_send.c.
5264 * Changed the setting on channel->on_channel = TRUE from the
5265 silc_client_save_channel_key to the JOIN command reply. The
5266 key payload is not received if the private channel key is set.
5267 Affected file lib/silcclient/command_reply.c and the
5268 lib/silcclient/client_channel.c.
5270 * When the CMODE_CHANGE notify is sent and the channel private
5271 key mode is removed the channel key must be re-generated in
5272 other cells as well. Added this support for the router in the
5273 silcd/packet_receive.c.
5275 * Added new local command NOTICE to send notice message on
5276 channel. Affected file silc/local_command.[ch].
5278 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5280 * Added new local command ME to the client. It is used to send
5281 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5282 some action. Affected file silc/local_command.[ch].
5284 * Changed channel_message and private_message client operations
5285 to deliver the message flags to the application. Added also
5286 the `flags' arguments to the silc_client_send_channel_message
5287 and silc_client_send_private_message functions. Affected file
5290 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5292 * Redefined the Private Message Payload to support private message
5293 keys and to support the new private message flags. Updated
5294 the protocol specs. Flags makes it possible to have for example
5295 CTCP style messages.
5297 * Added new type SilcPrivateMessagePayload and defined an API
5298 for it in the lib/silcclient/silcprivate.[ch].
5300 * Tested private message private keys successfully. Tested the
5301 private message key set, unset and list commands with the new
5304 * Redefined the Channel Message Payload to include the channel
5305 message flags (equal with private message flags) to support
5306 for example CTCP style messages.
5308 * Defined some of the message (for channel and private message)
5309 flags. Updated the protocol specs and added the flags to the
5310 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5312 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5314 * Added SilcKeyAgreementStatus type to the key agreement routines
5315 to indicate the current status and error if one occured.
5316 The status types are defined in the lib/silcclient/silcapi.h.
5318 * Added new local command KEY that is used to set and unset private
5319 keys for channels, set and unset private keys for private messages
5320 with remote clients and to send key agreement requests and
5321 negotiate the key agreement protocol with remote client. The
5322 key agreement is supported only to negotiate private message keys,
5323 it currently cannot be used to negotiate private keys for channels,
5324 as it is not convenient for that purpose.
5326 * Fixed a minor pending callback setting bug in the function
5327 silc_client_get_client_by_id_resolve, now the function works.
5328 Affected file lib/silcclient/idlist.c.
5330 * Added function silc_net_get_local_port to get local bound
5331 port by socket. Added to lib/silcutil/silcnet.[ch].
5333 * Added `sockets' and `sockets_count' fields to the SilcClient
5334 object. They hold the sockets of the listenning sockets in
5335 the client. Listenning sockets may be for example the key
5336 agreement server. Affected file lib/silcclient/client.[ch].
5337 Added functions the silc_client_add_socket and the
5338 silc_client_del_socket. They are exported to the application
5341 * Added ~./silc/clientkeys to support other client's public keys.
5343 * Renamed verify_server_key client operation to verify_public_key
5344 and added one argument to indicate the type of the connection
5345 (server, client etc.).
5347 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5349 * Added silc_server_connection_auth_request to handle the
5350 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5351 silcd/packet_receive.[ch].
5353 * Added silc_server_send_connection_auth_request into the
5354 silcd/packet_send.c to send the connection auth request packet.
5356 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5359 * Fixed the public key authentication in responder side in the
5360 server. The `auth_data' pointer includes the SilcPublicKey
5361 not the path to the public key. Affected file silcd/protocol.c.
5363 * Implemented the public key authentication in the initiator side
5364 in the server. Affected file silcd/protocol.c.
5366 * Removed the [RedirectClient] config section from the server
5367 configuration. Is not needed and I don't want to implement it.
5369 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5371 * Cleaned up the CMODE command in the server. It now works
5372 correctly and supports all the modes defined in the protocol.
5373 Affected file is silcd/command.c.
5375 * Added `hmac_name' field to the SilcChannelEntry in the server
5376 to hold the default HMAC of the channel. It can be set when
5377 creating the channel (with JOIN command). Affected files
5380 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5381 type to indicate the change of the current cipher and hmac
5382 on the channel. Client can safely ignore the <cipher> argument
5383 (if it chooses to do so) since the CHANNEL_KEY packet will
5384 force the channel key change anyway. The <hmac> argument is
5385 important since the client is responsible of setting the new
5386 HMAC and the hmac key into use.
5388 * Fixed the CMODE command in the client library as well.
5390 * Tested CMODE command in router environment successfully.
5392 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5394 * Show the version of the remote client (or server) when connecting
5395 to the server. It is logged to the log file. Affected file
5396 is silcd/protocol.c.
5398 * Fixed the KILLED notify handling in the client library. The
5399 client must be removed from all channels when receiving the
5402 Also, do not remove the client entry when giving the KILL
5403 command but when the KILLED notify is received.
5405 * Removed silc_idlist_find_client_by_nickname from the server.
5406 Not needed anymore. Affected files silcd/idlist.[ch].
5408 * Implemented the CHANNEL_CHANGE notify type handling to the
5409 server. Affected file silcd/server.c.
5413 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5415 * Added silc_server_send_notify_invite to send the INVITE
5416 notify between routers.
5418 * Implemented the INVITE command correctly to the server.
5420 * Implemented the INVITE notify type handling in the server.
5422 * Implemented the INVITE command to the client library and on the
5425 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5427 * Added function silc_server_get_client_resolve to find the
5428 client entry by ID from all ID lists and then resolve it
5429 (using WHOIS) if it cannot be found. Affected file is
5432 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5434 * Implemented the BAN command to the client library.
5436 * The JOIN command in the server now checks the invite list
5439 * Changed the silc_command_reply_payload_encode_va and the
5440 silc_command_payload_encode_va to support that if argument is
5441 NULL it ignores and checks the next argument. Affected file
5442 lib/silccore/silccommand.c.
5444 * Added silc_server_send_notify_ban to send the BAN notify
5445 type between routers.
5447 * Chaned the silc_notify_payload_encode to support that if
5448 argument is NULL it ignores and checks the next argument.
5449 Affected file lib/silccore/silcnotify.c.
5451 * Tested ban lists in router environment successfully.
5453 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5455 * Implemented BAN command to the server, in silcd/command.[ch].
5457 * Removed the BAN and INVITE_LIST modes from the CMODE command
5460 * Added function silc_string_match to regex match two strings.
5461 Affected files lib/silcutil/silcutil.[ch].
5463 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5465 * Redefined parts of the SilcChannelEntry in the server to support
5466 the new ban and invite lists.
5468 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5470 * Redefined the INVITE command. The same command can be used to
5471 invite individuals to the channel but also to manage the invite
5472 list of the channel (to add to and remove from the invite list).
5473 Updated the protocol specs.
5475 * Added new command SILC_COMMAND_BAN that can be used to manage
5476 the ban list of the channel. Updated the protocol specs.
5478 * Removed the channel modes: the SILC_CMODE_BAN and the
5479 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5480 in the CMODE command. The equivalent features are now available
5481 using INVITE and BAN commands. Updated the protocol specs.
5483 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5484 in the network about change in the current ban list. The notify
5485 type is not used by the client.
5487 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5488 support the invite lists.
5490 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5492 * Added new function silc_string_regexify that converts string
5493 including wildcard characters into regex string that can
5494 be used by the GNU regex library. Added into the file
5495 lib/silcutil/silcutil.[ch].
5497 Added silc_string_regex_combine to combine to regex strings
5498 into one so that they can be used as one regex string by
5499 the GNU regex library. Added into the file
5500 lib/silcutil/silcutil.[ch].
5502 Added silc_string_regex_match to match two strings. It returns
5503 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5505 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5507 * Imported GNU regex to the soruce tree into lib/contrib.
5508 Fixed some compiler warning from the regex.c.
5510 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5512 * Fixed MOTD command in the server to work in router environment.
5514 * Fixed the MOTD command in the client library to support
5515 the server argument in the command.
5517 * Added `nickname_len' argument to the silc_idlist_add_client
5518 in the server, as the `nickname' argument may be binary data
5521 * Added silc_idlist_get_channels to return all channels from
5524 * Implemented LIST command to the server. Affected file is
5527 * Implemented the LIST command to the client library and on the
5530 * Added [<user count>] argument to the LIST command reply.
5531 With private channels the user count is not shown.
5533 * Updated TODO and README.
5535 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5537 * The client entry's data.registered must be TRUE even with
5538 global client entry on global client list. The data.registered
5539 is used to check whether the client is anymore in the network,
5540 for example with WHOWAS command so it must be valid.
5542 * Fixed the WHOWAS command in the server. It now actually works
5543 in router environment. Added function into silcd/command_reply.c
5544 silc_server_command_reply_whowas_save.
5546 * Added silc_idlist_purge function to the silcd/idlist.c
5547 to periodically purge the ID Cache.
5549 * Fixed INFO command in the server. It works now in router
5550 environment. Added <server name> argument to the INFO command
5551 reply. Updated the protocol specs.
5553 * Fixed minor bug in silc_idcache_purge to not purge if the
5554 expire value is zero.
5556 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5557 they were buggy because of the WHOWAS information.
5559 * Fixed local command MSG to handle the async resolving of
5560 the remote client properly. It used to fail the first MSG.
5561 Affected file silc/local_command.c.
5563 * Added `data_len' field to SilcIDCache context.
5565 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5567 * Update TODO. Todo in commands in the server.
5569 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5571 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5572 used by routers as broadcast packet to inform other routers
5573 about the changed user mode.
5575 Implemented the notify handling in the server. Affected file is
5576 silcd/packet_receive.c. Added the function
5577 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5579 * Added new generic Channel Payload and deprecated the New Channel
5580 Payload. The New Channel Payload is now the generic Channel
5583 * Added new argument `mode' to the silc_server_send_new_channel
5584 as it is required in the Channel Payload now.
5586 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5587 and created a new and real SilChannelPayload to represent the
5588 new generic Channel Payload. Implemented the encode/decode
5589 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5591 * Added silc_server_get_client_channel_list to return the list
5592 of channels the client has joined for WHOIS command reply.
5593 Affected file silcd/server.[ch].
5595 * Implemented the channel list sending in the WHOIS command reply
5596 in server and in the client.
5598 Implemented the channel list displaying on the user interface
5599 as well. Affected file silc/client_ops.c.
5601 * Added silc_channel_payload_parse_list to parse list of Channel
5602 Payloads. It returns SilcDList list of SilcChannelPayloads.
5603 Client for example can use this function to parse the list of
5604 channels it receives in the WHOIS command reply. The caller
5605 must free the list by calling silc_channel_payload_list_free.
5606 Affected files lib/silccore/silcchannel.[ch].
5608 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5610 * Added one new argument <user mode> to the WHOIS command reply
5611 to return the mode of the user in SILC. Updated the protocol
5614 Implemented it to the server and client.
5616 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5618 * Fixed the mode printing on the user interface on joining.
5619 Affected file silc/client_ops.c.
5621 * Implemented the UMODE command and user modes in general to the
5622 client library and to the user interface.
5624 * Implemented the UMODE command to the server.
5626 * The server now sends UNKNOWN_COMMAND error status if client sends
5627 unknown command. Affected file silcd/command.c.
5629 * All server commands now handle the command identifier the right
5630 way when sending the command reply to the client. The client can
5631 use to identify the command replies with the identifier.
5633 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5635 * Added silc_server_get_client_route to resolve the route to
5636 the client indicated by the client ID. Affected file is
5639 * Added silc_server_relay_packet as general function to relay
5640 packet to arbitrary destination. This deprecates functions
5641 like _send_private_message_key, _relay_notify etc. Affected
5642 file is silcd/packet_send.[ch].
5644 Removed silc_server_send_key_agreement,
5645 silc_server_send_private_message_key and
5646 silc_server_packet_relay_notify functions from the file
5647 silcd/packet_send.[ch].
5651 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5652 server. Affected file silcd/packet_receive.[ch].
5654 * Implemented the KILL command to the client. Implemented the
5655 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5656 Affected files lib/silcclient/command[_reply].c and
5657 lib/silcclient/client_notify.c. Implemented the KILL notify
5658 printing in the user inteface.
5660 * Fixed a lot silc_parse_nick memory leaks from the client
5661 library in the file lib/silcclient/command.c.
5663 * Changed the silc_server_send_notify_on_channels's `sender'
5664 argument from SilcSocketConnection to SilcClientEntry to
5665 check the sender as entry and not as connection object and not
5666 to send to the client provided as argument. The affected file
5667 is silcd/packet_send.[ch].
5669 * The notify packets that are destined directly to the client used
5670 to not to be processed by the server. Now changed that and the
5671 server processes all notify packets. After relaying the packet
5672 to the client the notify packet is processed in the server.
5674 * The silc_server_free_client_data now checks whether there is
5675 pending outgoing traffic for the client and purges the data to
5676 the network before removing the client entry.
5678 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5680 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5681 an client is killed from the SILC Network. Updated the protocol
5684 Added new function silc_server_send_notify_killed to the
5685 silcd/packet_send.[ch].
5687 * Added function silc_server_packet_relay_notify to relay notify
5688 packets that are destined directly to a client. In this case
5689 the server does not process the notify packets but merely relays
5690 it to the client. Affected file silcd/packet_send.[ch].
5692 Added also silc_server_packet_process_relay_notify to check
5693 whereto relay the notify. Affected file is
5694 silcd/packet_receive.[ch].
5696 * Implemented the KILL command to the server.
5700 * Added the backup schema desgined last fall to the protocol
5701 specs for everyone to see. The specification is in the
5702 *-spec-xx.txt draft and the packet type definitions for the
5703 backup routers is in *-pp-xx.txt draft. Thusly, added also
5704 new packet type SILC_PACKET_CELL_ROUTERS.
5706 * A big security problem in the implementation discovered. The
5707 signoff of an client did not cause new channel key generation
5708 which it of course should've done. The channel keys must be
5709 always re-generated when client leaves (or signoffs) the channel.
5710 The silc_server_remove_from_channels funtion now handles
5711 the channel key re-generation.
5713 * Added `sender' argument to the silc_server_send_notify_on_channels
5714 to not to send the client provided as argument. Affected file
5715 silcd/packet_send.[ch].
5717 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5719 * Implemented OPER and SILCOPER commands into the server and
5722 * Added silc_auth_verify and silc_auth_verify_data to verify
5723 the authentication directly from the authentication payload.
5724 It supports verifying both passphrase and public key based
5725 authentication. Affected file lib/silccore/silcauth.[ch].
5727 * Added `hash' field to the SilcIDListData structure. It is the
5728 hash negotiated in the SKE protocol. Affected file is
5731 * Slight redesigning of the SilcAuthPayload handling routines.
5732 Do not send SilcPKCS but SilcPublicKey as argument.
5734 * Implemented the public key authentication support to the
5735 serverconfig. The public key is loaded from the provided path
5736 and saved as authentication data to void * pointer. Thus,
5737 changed the unsigned char *auth_data to void *auth_data;
5739 * Fixed SHUTDOWN command to send the reply before the server
5740 is shutdown. :) Affected file silcd/command.c.
5742 * Fixed fatal bug in CONNECT command. The hostname was invalid
5743 memory and server crashed. Affected file silcd/command.c.
5745 * Fixed fatal bug in CLOSE command. The server_entry became
5746 invalid but was referenced later in the command. Affected file
5749 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5751 * Fixed fatal bug in failure packet handling. Server ignored
5752 the failure and thus crashed when it came.
5756 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5758 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5759 that the command may be executed only once in (about) 2 seconds.
5760 The old SILC_CF_LAG flag is same but allows command bursts up
5761 to five before limiting.
5763 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5764 server code. Various commands now includes the CF_LAG_STRICT
5765 flag to disallow any kind of miss-use of the command.
5767 * Fixed the silc_buffer_unformat to not to allocate any data
5768 if the length of the data is zero. It used to allocate the
5769 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5771 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5773 * Changed the format of AdminConnection configuration section
5774 in the server. Added username of the admin to the format.
5775 Affected files silcd/serverconfig.[ch].
5777 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5778 to return admin configuration data by host, username and/or
5781 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5783 * Implemented WHOWAS command to the server. Added the functions:
5785 silc_server_command_whowas_parse,
5786 silc_server_command_whowas_send_reply,
5787 silc_server_command_whowas_from_client and
5788 silc_server_command_whowas_from_server
5790 * Added <Client ID> argument to the WHOWAS command reply. Updated
5791 the protocol specs accordingly.
5793 * Implemented WHOWAS command and command_reply to the client
5796 Implemented the WHOWAS printing on the user interface.
5798 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5800 * Added new argument to the WHOWAS command reply, the real name.
5801 It is an optional argument. Updated the protocol specs.
5803 * Added SilcIDCacheDestructor callback that is registered when
5804 the SilcIDCache is allocated. The callback is called when
5805 an cache entry in the ID Cache expires, or is purged from the
5806 cache. Added into lib/silccore/idcache.[ch].
5808 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5809 to destruct the client entries when the cache entry expires.
5810 Other ID Cache's in server and in the client library ignores
5813 * If the ID Cache entry's `expire' field is zero then the entry
5814 never expires. Added boolean `expire' argument to the
5815 silc_idcache_add function in the lib/silccore/idcache.[ch].
5816 If it is TRUE the default expiry value is used.
5818 * Added silc_server_free_client_data_timeout that is registered
5819 when client disconnects. By default for 5 minutes we preserve
5820 the client entry for history - for WHOWAS command.
5822 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5824 * Added support to the server to enforce that commands are not
5825 executed more than once in 2 seconds. If server receives
5826 commands from client more frequently, timeout is registered
5827 to process the commands. Affected file silcd/command.c.
5828 Added new function silc_server_command_process_timeout.
5830 * Changed NICK_NOTIFY handling in client library to check that
5831 if the client's nickname was changed, so there is no need to
5832 resolve anything from the server.
5834 * Removed error printing from the WHOIS and IDENTIFY commands.
5835 If error occurs then it is ignored silently in the client library.
5836 The application, however, may map the received error to
5837 human readable error string. The application currently maps
5838 the NO_SUCH_NICKNAME error to string.
5840 * Made the command status message public to the application. Moved
5841 them from lib/silcclient/command_reply.c to
5842 lib/silcclient/command_reply.h. The application can map the
5843 received command status to the string with the
5844 silc_client_command_status_message function.
5846 * Added check to the server to check that client's ID is same
5847 as the Source ID in the packet the client sent. They must
5850 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5852 * Added dist-bzip hook to the Makefile.am to make bzip2
5853 compressed distributions.
5855 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Server now enforces the maximum length for the nickname and
5858 the channel as protocol specification dictates. 128 bytes for
5859 nickname and 256 bytes for channel name.
5861 * Moved the WHOIS printing to the application. The client libary
5862 does not print out the WHOIS information anymore, the application
5863 must do it. Renamed silc_client_command_reply_whois_print to
5864 the silc_client_command_reply_whois_save.
5866 The client's idle time is also sent to the application now, and
5867 the idle is shown on screen.
5869 * Added silc_client_command_reply_identify_save to save the
5870 received IDENTIFY entries.
5872 * Do not check for channel private keys in message sending and
5873 reception if the channel does not have the PRIVKEY mode set.
5874 Affected file lib/silclient/client_channel.c.
5876 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5879 just surfaced after chaning the JOIN procedure.
5881 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * Added silc_client_get_clients_by_list to get client entries
5884 from Client ID list, that is returned for example by JOIN
5885 and USERS command replies. The application should use this
5886 function for example when JOIN command reply is received to
5887 resolve the clients already on the channel (library does not
5888 do that anymore as USERS command reply is not used in the JOIN
5889 procedure anymore). Affected files lib/silcclient/silcapi.h and
5890 lib/silcclient/idlist.c.
5892 * JOIN command reply and USERS command reply returns now SilcBuffer
5893 pointers instead of unsigned char pointers when returning
5894 the client list and mode list.
5896 * Added <Client ID> argument to the JOIN command reply, mainly
5897 for the server to identify for which client the command was
5898 originally sent. Updated protocol specs accordingly.
5900 * Added SilcDlist private_key pointer to the SilcChannelEntry
5901 in the client to support the channel private keys. Affected
5902 file is lib/silcclient/idlist.h.
5904 * Added SilcChannelPrivateKey argument to the function
5905 silc_client_send_channel_message so that application can choose
5906 to use specific private ke if it wants to. If it is not provided,
5907 the normal channel key is used, unless private keys are set.
5908 In this case the first (key that was added first) is used
5909 as the encryption key.
5911 * Implemented the support for channel private key handling.
5912 Implemented the following functions:
5914 silc_client_add_channel_private_key,
5915 silc_client_del_channel_private_keys,
5916 silc_client_del_channel_private_key,
5917 silc_client_list_channel_private_keys and
5918 silc_client_free_channel_private_keys
5920 Affected file lib/silcclient/client_channel.c.
5922 * Added the support for the private keys in the channel message
5923 sending and encryption and in the message reception and
5924 decryption. Affected funtions are
5925 silc_client_send_channel_message and silc_client_channel_message.
5927 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5929 * Added SKE's key verify callback to the client library's
5930 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5932 * Removed the statement that server (or router) must send USERS
5933 command reply when joining to the channel so that the client
5934 knows who are on the channel. Instead, the client list and
5935 client's mode list is now sent in the JOIN command reply to the
5936 client who joined channel. This is better solution.
5938 * Added function silc_server_get_users_on_channel and function
5939 silc_server_save_users_on_channel to the silcd/server.[ch].
5941 * Removed function silc_server_command_send_users from the
5944 * Do not show topic on the client library anymore. The topic is
5945 sent in the command reply notify to the application and the
5946 application must show the topic now.
5948 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Added client searching by nickname hash into the IDENTIFY and
5951 WHOIS commands in the server as they were clearly missing from
5952 them. Affected file is silcd/command.c.
5954 * Fixed a bug in private message receiving in the client library.
5955 The remote ID was freed and it wasn't supposed, now it is
5958 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5960 * Minor fix to the channel payload; allocate the data area, as it
5961 needs to be of specific length.
5963 * If the key agreement port is zero then the operating
5964 system will define the bound port. Affected files are
5965 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5967 * Added new function silc_channel_payload_decrypt into the file
5968 lib/silccore/silcchannel.[ch].
5970 * Moved the channel message etc, check from silc_packet_decrypt
5971 to applications. The library calls now a generic
5972 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5973 when the packet is either normal or special. This was done to
5974 allow more wide range of checking that was not allowed when
5975 the code was in library. Now applications can do virtually any
5976 checks to the packet and return to the library the decision how
5977 the packet should be processed. Affected files are
5978 lib/silccore/silcpacket.[ch].
5980 Added silc_server_packet_decrypt_check to the server and
5981 silc_client_packet_decrypt_check to the client library.
5983 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5984 to send with specified source and destination information.
5986 * Channel message delivery between routers was broken after the
5987 channel key distribution was fixed earlier. The channel key
5988 was used be to distributed to other routers as well which is not
5989 allowed by the protocol. Now this is fixed and channel keys
5990 really are cell specific and the channel message delivery between
5991 routers comply with the protocol specification.
5993 * Fixed various commands in server to check also the global list
5994 for the channel entry and not just the local list. The affected
5995 file silcd/command.c.
5997 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5999 * Added assert()s to buffer formatting and unformatting routines
6000 to assert (if --enable-debug) when error occurs. Affected
6001 file: lib/silcutil/silcbuffmt.c.
6003 * Changed to auto-reconnect to check whether the remote host is
6004 router and register the re-connect timeout if it is. It used
6005 to check that whether we are normal server, but router must do
6006 auto-reconnect with another router as well. Affected file
6009 * Removed the [<key len>] option from CMODE command as the cipher
6010 name decides the key length, nowadays. See the defined ciphers
6011 from the protocol specification.
6013 * Added [<hmac>] option to the CMODE command to define the HMAC
6014 for the channel. Added SILC_CMODE_HMAC channel mode.
6016 * Added [<hmac>] option for the JOIN command so that user can
6017 select which HMAC is used to compute the MACs of the channel
6020 * Added Hmac field to the Channel Message Payload. The integrity
6021 of plaintext channel messages are now protected by computing
6022 MAC of the message and attaching the MAC to the payload. The
6023 MAC is encrypted. Now, it is clear that this causes some
6024 overhead to the size of the packet but rationale for this is that
6025 now the receiver can verify whether the channel message decrypted
6026 correctly and also when private keys are set for the channel the
6027 receiver can decrypt the packet with several keys and check from
6028 the MAC which key decrypted the message correctly.
6030 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6031 lib/silccrypt/silccipher.[ch].
6033 * Added silc_hash_len to return the digest length into the
6034 lib/silcrypt/silchash.[ch].
6036 * Rewrote parts of Silc Channel Payload interface in the
6037 lib/silccore/silcchannel.[ch]. The encode function now also
6038 encrypts the packet and parse function decrypts it.
6040 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6042 * Fixed a minor formatting bug in the SKE's key material processing.
6043 It actually might have processed the keys wrong way resulting
6046 * Redefined the mandatory HMAC algorithms and added new algorithms.
6047 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6048 and hmac-md5 truncated to 96 bits. The mandatory is now
6049 hmac-sha1-96. Rest are optional (including the one that used
6050 to be mandatory). Rationale for this is that the truncated HMAC
6051 length is sufficient from security point of view and can actually
6052 make the attack against the HMAC harder. Also, the truncated
6053 HMAC causes less overhead to the packets. See the RFC2104 for
6056 * Added new [hmac] configuration section. The SKE used to use
6057 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6058 is of course wrong. The official names that must be proposed in
6059 the SKE are the ones defined in the protocol specification
6060 (hmac-sha1-96 for example). The user can configure any hmac
6061 using any hash function configured in the [hash] section. At
6062 least, the mandatory must be configured.
6064 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6066 * Added HMAC list to the SKE proposal list. It has now both
6067 hash algorithm list and HMAC list. This makes the protocol
6068 incompatible with previous versions. The SKE now seems to work
6069 the way it is supposed to work, for the first time actually.
6071 * Defined plain Hash algorithms to the protocol specification.
6074 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6076 * Implemented support for key agreement packets into the server.
6077 Added functions silc_server_key_agreement and
6078 silc_server_send_key_agreement. Other than these functions,
6079 server has nothing to do with this packet.
6081 * Added support for private message key packets into the server.
6082 Added functions silc_server_private_message_key and
6083 silc_server_send_private_message_key.
6087 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6088 called in the protocol's final callback instead in the END
6089 protocol state. This makes a little more sense and in the same
6090 time in client we can use the same protocol routines for normal
6091 key exchange and to key agreement packet handling as well.
6093 * Added to both client's and server's KE protocol context the
6094 SilcSKEKeyMaterial pointer to save the key material. We will
6095 bring the key material to the protocol's final callback by doing
6096 this. The final callback must free the key material.
6098 * Added SKE's packet_send callback into client's KE protocol
6099 context so that the caller can choose what packet sending function
6100 is used. This way we can use different packet sending when
6101 doing normal SKE when doing key agreement packet handling (in
6102 the key agreement packet handling we do not want to encrypt
6105 * Implemented the responder side of the key agreement routines
6106 in the client. The client can now bind to specified port and
6107 accept incoming key negotiation. The key material is passed
6108 to the application after the protocol is over.
6110 * Implemented the processing of incoming Key Agreement packet
6111 in the client. Added function silc_client_key_agreement to
6114 * Implemented the intiator side of the key agreement routines
6115 in the client. The client can now initiate key agreement with
6116 another remote client. The key material is passed to the
6117 application after the protocol is over.
6119 * Created client_keyagr.c to include all the key agreement
6122 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6123 SILC_TASK_CALLBACK except that it is not static.
6125 * Created client_notify.c and moved the Notify packet handling
6126 from the client.[ch] into that file.
6128 * Created client_prvmsg.c and moved all private message and
6129 private message key routines from the client.[ch] into that file.
6131 * Create client_channel.c and moved all channel message and
6132 channel private key routines from the client.[ch] into that file.
6134 * Changed silc_client_get_client_by_id_resolve to resolve with
6135 WHOIS command instead of IDENTIFY command, in the file
6136 lib/silclient/idlist.c.
6138 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6140 * Implemented the SKE's responder side to the Client library.
6142 * When FAILURE is received to the protocol do not trust it
6143 blindly. Register a timeout to wait whether the remote closes
6144 the connection as it should do it, only after that process the
6145 actual failure. This was changed to both client and server.
6147 * Added client_internal.h to include some of the structures
6148 there instead of client.h in lib/silcclient/.
6150 * Added function silc_task_unregister_by_callback to unregister
6151 timeouts by the callback function.
6153 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6155 * Some "Incomplete WHOIS info" errors has been appearing on the
6156 log files. Took away the entry->userinfo check from WHOIS
6157 reply sending. The entry->userinfo is now " " if client did not
6158 provide one. I thought this was fixed earlier but something
6159 is wrong still. Let's see if the error still appears.
6161 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6163 * Fixed a minor bug in the login when the channel key is
6164 re-generated in the server. It used to generate the key in
6165 wrong order and thus caused problems in the channel traffic.
6167 * Fixed a minor bug in channel key distsribution after
6168 KICK command. The key was not sent to the router even though
6171 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6173 * Added silc_ske_process_key_material_data as generic routine
6174 to process any key material as the SILC protocol dictates. The
6175 function is used by the actual SKE library but can be used by
6176 applications as well. This relates to the private message keys
6177 and the channel private keys since they must be processed the
6178 same way the normal SILC session keys. The protocol dictates
6179 this. Affected files: lib/silcske/silcske.[ch].
6181 Added also silc_ske_free_key_material to free the
6182 SilcSKEKeyMaterial structure.
6184 * Defined silc_cipher_set_key function to set the key for
6185 cipher without using the object's method function. The affected
6186 files: lib/silccrypt/silccipher.[ch].
6188 * Implemented silc silc_client_add_private_message_key,
6189 silc_client_add_private_message_key_ske,
6190 silc_client_del_private_message_key,
6191 silc_client_list_private_message_keys and
6192 silc_client_free_private_message_keys functions in the
6195 Added functions silc_client_send_private_message_key to send
6196 the Private Message Key payload and silc_client_private_message_key
6197 to handle incoming Private Message Key payload.
6199 * Added Cipher field to the Private Message Key payload to set
6200 the cipher to be used. If ignored, the default cipher defined
6201 in the SILC protocol (aes-256-cbc) is used.
6203 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6205 * Removed lib/silcclient/ops.h file.
6207 Redefined parts of the SILC Client Library API. Created new
6208 file silcapi.h that deprecates the ops.h file and defines the
6209 published Client Library API. Defined also private message key
6210 API and channel private key API into the file.
6212 This is the file that the application must include from the
6213 SILC Client Library. Other files need not be included by
6214 the application anymore.
6216 * Added new key_agreement client operation callback and also
6217 defined the Key Agreement library API for the application.
6219 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6221 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6222 is used by clients to request key negotiation between another
6223 client in the SILC network. If the negotiation is started it
6224 is performed using the SKE protocol. The result of the
6225 negotiation, the secret key material, can be used for example
6226 as private message key.
6228 Implemented the Key Agreement payload into the files
6229 lib/silccore/silauth.[ch].
6231 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6233 * Redefined ciphers for the SILC protocol. Added some new ciphers
6234 and defined the key lengths for the algorithms. Changed the
6235 code accordingly. The default key length is now 256 bits.
6237 * Fixed SKE key distribution function silc_ske_process_key_material
6238 when the key length is more than 128 bits. The default key
6239 length in SILC is now 256 bits.
6241 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6242 to indicate unsupported algorithm.
6244 * Renamed rijndael.c to aes.c and all functions as well.
6246 * Fixed a long standing channel key setting bug in client library.
6247 Weird that it has never surfaced before.
6249 * Fixed bug in channel deletion. If the entire channel is removed
6250 then it must also delete the references of the channel entry
6251 from the client's channel list as the client's channel entry and
6252 the channel's client entry share same memory.
6254 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * Implemented CONNECT and SHUTDOWN commands in the client.
6258 * Implemented CLOSE command to the client.
6260 * Added the function silc_idlist_find_server_by_name into the
6261 files silcd/idlist.[ch].
6263 Added the function silc_idlist_find_server_by_conn into the
6264 files silcd/idlist.[ch].
6266 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6268 * DIE command was renamed to SHUTDOWN. Updated the both code
6271 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6272 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6274 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6277 * Added function silc_server_create_connection function to create
6278 connection to remote router. My server implementation actually
6279 does not allow router to connect to normal server (it expects
6280 that normal server always initiates the connection to the router)
6281 so the CONNECT command is only good for connecting to another
6284 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6286 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6287 or some other client was kicked from the channel.
6289 Implemented the handling of the notify type to both client
6292 Implemented silc_server_send_notify_kicked to send the KICKED
6293 notify. It is used to send it to the server's primary router.
6295 * Implemented the KICK command into server and client.
6297 * Added `query' argument to the silc_idlist_get_client function
6298 to indicate whether to query the client from server or not if
6301 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6302 to indicate that the client is not channel founder.
6306 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6308 * Removed the rng context from SilcPacketContext structure and
6309 changed that the packet routine uses the Global RNG API.
6311 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6313 * Added support for quit message that client can "leave" on the
6314 channel when it quits the SILC. It is ditributed inside the
6315 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6317 Added silc_server_free_client_data that will take the
6318 signoff message as argument.
6320 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6322 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6324 * Updated parts of the protocol specification to keep it up
6327 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6330 payloads in one packet.
6332 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6333 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6334 use now the new List flag.
6336 * Also deprecated the following packet types: REPLACE_ID,
6337 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6339 * Added list support for Notify packet in server.
6341 * Added silc_server_send_notify_channel_change to send the
6342 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6343 the silc_server_send_replace_id.
6345 * Added silc_server_send_notify_nick_change to send the
6346 NICK_CHANGE notify type. Deprecates the function
6347 silc_server_send_replace_id.
6349 * Added silc_server_send_notify_join to send the JOIN notify type.
6350 Deprecates the function silc_server_send_new_channel_user.
6352 * Added silc_server_send_notify_leave to send LEAVE notify type.
6353 Deprecates the function silc_server_send_remove_channel_user.
6355 * Added silc_server_send_notify_cmode and
6356 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6357 types. Deprecates the silc_server_send_set_mode function.
6359 * Added SERVER_SIGNOFF notify type to indicate that server has
6360 quit. This means that all clients on the channel from that
6361 server will drop. This can be also used when netsplit happens.
6363 Deprecated REMOVE_ID packet type since it is not needed anymore
6366 Added silc_server_send_notify_server_signoff to send the
6367 SERVER_SIGNOFF notify type. Deprecates the function
6368 silc_server_send_remove_id.
6370 Added also silc_server_send_notify_signoff to send the
6371 SIGNOFF notify type.
6373 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6374 SILC protocol from this day on. Changed the protocol
6375 specification as well.
6377 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6378 notify type. It is used between routers to notify about
6379 topic changes on a channel.
6381 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6384 * Partly updated the protocol specification to comply with the
6385 changes now made. It is still though a bit outdated.
6387 * The JOIN notify type now takes one extra argument <Channel ID>.
6388 The packet used to be destined to the channel but now the
6389 JOIN type may be sent as list thus it is impossible to
6390 destine it to any specific channel. By adding this argument
6391 it is again possible.
6393 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6395 * Added CREDITS file. The CHANGES and CREDITS file will appear
6396 in the distribution as well.
6398 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6400 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6401 types in the server's silcd/packet_receive.c.
6403 * Implemented CMODE and CUMODE to work in router environment.
6405 * Fixed minor encoding and decoding buglet from the
6406 lib/silccore/silcmode.c.
6408 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6411 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6413 * Changed all SilcConfigServer* and silc_config_server* to
6414 SilcServerConfig* and silc_server_config*, respectively.
6417 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6419 * Associated the ID (client or server ID) to the Authentication
6420 Payload to avoid any possibility of forging. Updated the
6421 protocol specification and the code accordingly.
6423 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6425 * The RSA key length is now save to the RsaKey context in the
6426 key generation process in lib/silccrypt/rsa.c. The key length
6427 is now used to figure out the maximum size of the block allowed
6428 to be encrypted/signed.
6430 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6431 is equivalent to the silc_mp_mp2bin but does not allocate any
6434 * Changed silc_mp_mp2bin API to take length argument. If it is
6435 non-zero then the buffer is allocated that large. If zero, then
6436 the size is approximated using silc_mp_sizeinbase, which however
6439 * Created Global RNG API which is global RNG that application can
6440 initialize. After initializing, any routine anywhere in the
6441 code (including library) can use RNG without allocating a new
6442 RNG object. This was done to allow this sort of use of the
6443 RNG in code that has no chance to allocate RNG object. All
6444 applications currently allocate this and many routines in the
6445 library use this. Affected file lib/silccrypt/silcrng.[ch].
6447 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6448 it to use the Global RNG API.
6450 * Defined Authentication Payload into protocol specification that
6451 is used during SILC session to authenticate entities. It is
6452 used for example by client to authenticate itself to the server
6453 to obtain server operator privileges.
6455 Implemented this payload into the lib/silccore/silcauth.[ch].
6456 Implemented also routines for public key based authentication
6457 as the new protocol specification dictates.
6459 Moved definitions of different authentication methods from
6460 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6462 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6463 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6464 silc_pkcs_verify_with_hash functions into the file
6465 lib/silccrypt/silcpkcs.[ch].
6467 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6469 * The client entry's userinfo pointer must be always valid.
6470 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6471 will fail since it requires the userinfo. Now, the userinfo
6472 is allocated as "" if actual userinfo does not exist. Actually,
6473 it must exist and it is totally Ok to drop client connections
6474 that does not announce the userinfo. However, we will make
6475 this workaround for now.
6477 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6478 to return the remote port by socket.
6480 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6482 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6483 SILC_SERVER_PENDING_EXEC and added an new macro
6484 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6485 data or when error occurs while processing the pending command.
6487 Added new argument `destructor' into silc_server_command_pending
6488 and to the SilcServerCommandPending object. This destructor is
6489 now called after calling the pending callback or if error occurs
6490 immediately. If error occurs the actual pending callback won't
6491 be called at all - only the destructor. The destructor may be
6492 NULL if destructor is not needed.
6494 All this applies for client library code as well. Similar
6495 changes were made there as well for the pending commands.
6497 In the client, the application must now allocate the
6498 SilcClientCommandContext with the silc_client_command_alloc
6501 * Added reference counter to the SilcServerCommandContext. Added
6502 function silc_server_command_alloc and silc_server_command_dup
6505 Same type of functions added to the client library for the same
6508 * Removed the cmd_ident from IDListData away since it is now
6509 global for all connections. It is the command identifier used
6510 in command sending and with pending commands. The affected file
6513 * Added reference counter to the SilcSocketConnection objecet to
6514 indicate the usage count of the object. The object won't be
6515 freed untill the reference counter hits zero. Currently only
6516 server uses this, and client ignores it. The client must be
6517 set to use this too later. The affected files are
6518 lib/silccore/silcsockconn.[ch]. Added also the function
6519 silc_socket_dup to increase the reference counter.
6521 This was mainly added because it is possible that the socket
6522 is removed underneath of pending command or other async
6523 operation. Now it won't be free'd and proper DISCONNECTING
6524 flags, etc. can be set to avoid sending data to connection that
6525 is not valid anymore.
6527 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6528 the connection. After that it sets SILC_SET_DISCONNECTED.
6529 It is, however, possible that the socket data is not still freed.
6530 The silc_server_packet_process now checks that data is not
6531 read or written to connection that is DISCONNECTED. The socket
6532 get's freed when the reference counter hits zero.
6534 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6536 * Changed the client operation API: channel_message operation's
6537 `sender' is now the client entry of the sender, not the nickname
6538 and the `channel' is the channel entry, not the channel name.
6540 In the private_message operation the `sender' is now also the
6541 client entry of the sender not the nickname.
6543 Affected file is lib/silcclient/ops.h and all applications
6544 using the client operations.
6546 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6548 * Moved the calling of ops->connect() from connect_to_server_final
6549 into receive_new_id functin since that is the point when the
6550 client is actually allowed to send traffic to network. The
6551 affected file is lib/silcclient/client.c.
6553 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6555 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6556 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6557 (if needs broadcasting) instead of broadcasting the packets one
6558 by one which would make a burst in the network traffic.
6560 * Added `broadcast' argument to the functions in silcd/server.[ch]
6561 silc_server_create_new_channel[_with_id] to indicate whether
6562 to send New Channel packet to primary router.
6564 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6566 * Added new function into the silcd/server.[ch] files:
6567 silc_server_create_new_channel_with_id to create new channel with
6568 already existing Channel ID.
6570 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6571 lib/silccore/silcpacket.h. This packet is used t send list of
6572 Set Mode payloads inside one packet. Server uses this to set
6573 the modes for the channels and clients on those channels, that it
6574 announced to the router when it connected to it. The protocol
6575 specification has been updated accordingly.
6577 * The silc_server_new_channel did not handle the packet coming
6578 from normal server as it normally does not send that. However,
6579 when it announces its channels it does send it. Implemented
6580 the support for that.
6582 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6583 into the file lib/silccore/id.h.
6585 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6587 * Fixed memory leaks in the functions silc_idlist_del_client,
6588 silc_idlist_del_channel and silc_idlist_del_server in the file
6589 silcd/idlist.c. All of those leaked like a sieve.
6591 * Fixed some small memory leaks in the client's function
6592 silc_client_notify_by_server.
6594 * Added functions into silcd/server.c: silc_server_announce_clients,
6595 silc_server_announce_channels and silc_server_announce_server.
6596 These functions are used by normal and router server to announce
6597 to its primary router about clients, channels and servers (when
6598 router) that we own. This is done after we've connected to the
6601 These functions effectively implements the following packet types:
6602 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6603 and SILC_PACKET_NEW_ID_LIST.
6605 * Added new functions into the silcd/packet_receive.[ch]:
6606 silc_server_new_id_list, silc_server_new_channel_list and
6607 silc_server_new_channel_user_list to handle the incoming
6608 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6610 * Added support of changing Channel ID in the function
6611 silc_server_replace_id. If the server that announces a channel
6612 to the router already exists in the router (with same name but
6613 with different Channel ID), router is responsible to send
6614 Replace ID packet to the server and force the server to change
6615 the Channel ID to the one router has.
6617 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6618 client that the Channel ID has been changed by the router. The
6619 normal server sends this to the client. Client must start using
6620 the new Channel ID as the channel's ID.
6622 Implemented handling of this new type into lib/silcclient/client.c
6623 into the function silc_client_notify_by_server.
6625 * Added new function silc_idlist_replace_channel_id into the files
6626 silcd/idlist.[ch] to replace the Channel ID.
6628 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6630 * Call silc_server_command_identify_check always when processing
6631 the IDENTIFY command in silcd/command.c
6633 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6635 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6636 send keepalive packets. The packet can be sent by clients,
6637 servers and routers.
6639 Added function silc_socket_set_heartbeat into the file
6640 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6641 If not set, the heartbeat is not performed. The actual
6642 heartbeat is implemented in the low level socket connection
6643 library. However, application is responsible of actually
6646 Added silc_server_send_heartbeat to send the actual heartbeat
6647 packet into silcd/packet_send.[ch]. Server now performs
6648 keepalive with all connections.
6650 * Added silc_task_get_first function into lib/silcutil/silctask.c
6651 to return the timeout task with shortest timeout. There was a bug
6652 in task unregistration that caused problems. TODO has been
6653 updated to include that task system must be rewritten.
6655 * The client library will now resolve the client information when
6656 receiving JOIN notify from server for client that we know but
6657 have incomplete information.
6659 * Rewrote parts of silc_server_remove_from_channels and
6660 silc_server_remove_from_one_channel as they did not remove the
6661 channel in some circumstances even though they should've.
6663 * Encryption problem encountered in server:
6665 The LEAVE command used to send the Channel Key packet to the
6666 router immediately after generating it. However, the code
6667 had earlier sent Remove Channel user packet but not immediately,
6668 ie. it was put to queue. The order of packets in the router
6669 was that Channel Key packet was first and Remove Channel User
6670 packet was second, even though they were encrypted in the
6671 reverse order. For this reason, MAC check failed. Now, this
6672 is fixed by not sending the Channel Key packet immediately but
6673 putting it to queue. However, this is more fundamental problem:
6674 packets that are in queue should actually not be encrypted
6675 because packets that are sent immediately gets encrypted
6676 actually with wrong IV (and thus MAC check fails). So, packets
6677 that are in queue should be encrypted when they are sent to
6678 the wire and not when they put to the queue.
6680 However, the problem is that the current system has not been
6681 designed to work that way. Instead, the packet is encrypted
6682 as soon as possible and left to the queue. The queue is then
6683 just purged into wire. There won't be any fixes for this
6684 any time soon. So, the current semantic for packet sending
6687 o If you send packet to remote host and do not force the send
6688 (the packet will be in queue) then all subsequent packets to the
6689 same remote host must also be put to the queue. Only after the
6690 queue has been purged is it safe again to force the packet
6693 o If you send all packets immediately then it safe to send
6694 any of subsequent packets through the queue, however, after
6695 the first packet is put to queue then any subsequent packets
6696 must also be put to the queue.
6698 Follow these rules and everything works fine.
6700 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6702 * Added new function silc_server_remove_clients_by_server to
6703 remove all client entries from ID list when the server connection
6704 is lost. In this case it is also important to invalidate all
6705 client entires as they hold the invalid server entry. This
6706 fixes fatal bug when server has lost connection and will reconnect
6709 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6711 * Made some sanity checks to silc_server_daemonise like to check
6712 whether the requested user and group actually exists.
6714 * Added sanity check to SKE's silc_ske_responder_finish to check
6715 that the public and private key actually is valid.
6717 * Invalidate the client's nickname when receiving Replace ID
6718 packet and the Client ID is being replaced. This means that the
6719 server will query the nickname if someone needs it (client)
6722 * Sort the ID Cache in client library when the ID Cache data
6723 has changed (needs sorting).
6725 * Do not allow for SILC client to create several connections to
6726 several servers. The client does not support windows right now
6727 and generating multiple connections causes weird behaviour.
6729 Irssi-silc client does support windows and can handle several
6730 connections without problems, see: www.irssi.org and SILC plugin.
6732 * Fixed some places where client was added to the IDList. The
6733 rule of thumb is following (in order to get everything right):
6734 If the client is directly connected local client then the
6735 `connection' argument must be set and `router' argument must be
6736 NULL to silc_idlist_add_client function. If the client is not
6737 directly connected client then the `router' argument must
6738 bet set and the `connection' argument must be NULL to the
6739 silc_idlist_add_client function.
6741 * The funtion silc_server_packet_send_local_channel actually did
6742 not check whether the client was locally connected or not. It
6743 does that now. Fixed a bug related to LEAVE command.
6745 * Fixed Remove Channel User payload parsing bug in server's
6746 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6748 * The server's silc_server_save_channel_key now checks also the
6749 global ID list for the channel as it might not be in the local
6750 list. Fixed a bug related to LEAVE command.
6752 * Is this the end of the [<unknown>] buglet that has been lurking
6753 around for a long time? A little for loop fix in server's
6754 silc_server_command_whois_parse that is used by both IDENTIFY
6755 and WHOIS command. At least, this was a clear bug and a cause
6756 of one type of [<unknown>] buglet.
6758 * WHOIS and IDENTIFY commands call the function
6759 silc_server_command_[whois/identify]_check function even if
6760 we are not router server.
6762 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6764 * Added --with-gmp configuration option. If set the GMP
6765 is always compiled in the SILC source tree. If not set then
6766 it is checked whether the system has the GMP3 installed. If
6767 it has then the GMP won't be compiled (the system's headers
6768 and library is used), if it doesn't have it then the GMP is
6769 compiled in the SILC source tree.
6771 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6773 * Changed RSA private exponent generation to what PKCS #1
6774 suggests. We try to find the smallest possible d by doing
6775 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6776 not security fix but optimization.
6778 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6780 * Added new config entry [Identity] to fork the server and run
6781 it as specific user and group. A patch from Bostik.
6783 * Imported Dotconf configuration library into lib/dotconf.
6784 This will be used to create the SILC configuration files later.
6785 It will appear in the distsribution after this commit.
6787 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6789 * A big code auditing weekend happening. Auditing code for
6790 obvious mistakes, bugs and errors. Also, removing any code
6793 Removed files for being obsolete:
6795 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6796 inline in the file lib/silcutil/silcbuffer.h)
6798 o lib/silcutil/silcbufutil.c (the header has inline versions)
6800 Changed code to fix possible error conditions:
6802 o The buffer formatting routines now check that the destination
6803 buffer really has enough space to add the data. This applies for
6804 both buffer formatting and unformatting
6805 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6806 unformatting was changed to accomodate following rules:
6807 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6808 sent to the function while XXX_*STRING will not allocate or copy
6809 the data into the buffer. Instead it sets the pointer from the
6810 buffer into the pointer sent as argument (XXX_*STRING used to
6811 require that the pointer must be allocated already). This change
6812 makes this whole thing a bit more consistent and more optimized
6813 (note that the data returned in the unformatting with XXX_*STRING
6814 must not be freed now). The routines return now -1 on error.
6816 o Tried to find all code that use buffer_format and buffer_unformat
6817 and added return value checking to prevent formatting and
6818 especially unformatting errors and possible subsequent fatal
6821 o Changed ske->x and ske->KEY to mallocated pointers in
6822 lib/silcske/silcske.h. Fixed possible data and memory leak.
6824 o Added return value checking to all *_parse* functions. Fixed
6825 many memory leaks as well.
6827 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6828 so that buffer overflows would not happen. All code now also
6829 checks the return value as it can fail.
6831 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6833 * Added reconnection support to server if the normal server looses
6834 its connection to the router (for example if router is rebooted).
6835 The server performs normal reconnection strategy implemented
6836 to the server. Affected file silcd/server.c.
6838 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6840 * Added new packet type SILC_PACKET_SET_MODE that is used to
6841 distribute the information about changed modes (for clients,
6842 channels and clients channel modes) to all routers in the
6843 network. Updated the protocol specification accordingly.
6845 Added functions into silcd/packet_send.c and
6846 silcd/packet_receive.c: silc_server_send_set_mode,
6847 silc_server_set_mode.
6849 Added new files silcmode.[ch] into lib/silccore that implements
6850 the encoding and decoding of Set Mode Payload. Added new type
6851 SilcSetModePayload. Moved the definitions of different modes
6852 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6854 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6856 * Oops, a little mistake in server's connection authentication
6857 protocol. The protocol is not ended with FAILURE but with
6858 SUCCESS if the authentication is Ok. :) Affected file is
6861 * Implemented NICK_CHANGE notify handling in server in the file
6862 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6863 the local clients on the channel. After the changing nickname
6864 in router environment snhould work and the [<unknown>] nickname
6865 should appear no more.
6867 The silc_server_replace_id function that receives the Replace ID
6868 payload now sends the NICK_CHANGE notify type also in the file
6869 silcd/packet_receive.c
6871 * Changed WHOIS and IDENTIFY command to support the maximum amount
6872 of arguments defined in protocol specs (3328 arguments). This
6873 fixed a bug that caused problems when there were more than three
6876 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6878 * Added extra parameter, command identifier, to the
6879 silc_client_send_command so that explicit command identifier
6882 Changed that ID list routines uses specific command identifier
6883 when sending WHOIS/IDENTIFY requests to the server so that they
6884 can be identified when the reply comes back.
6886 Affected files lib/silcclient/command.[ch],
6887 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6889 * Added `sender' argument to silc_server_packet_send_to_channel
6890 to indicaet the sender who originally sent the packet to us
6891 that we are now re-sending. Ignored if NULL. Affected file
6892 silcd/packet_send.[ch].
6894 * Added some server statistics support in silcd/server_internal.h
6895 SilcServerStatistics structure and around the server code. Also
6896 send some nice statistics information when client is connecting
6899 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6901 * Fixed channel ID decoding in server's JOIN command reply in
6902 silcd/command_reply.c
6904 * Fixed braodcasting of replace ID payload to not to send it if
6905 we are standalone server in silcd/packet_receive.c.
6907 * Fixed all channel message sending routines to not to send
6908 packets to clients that has router set, since they are routed
6909 separately in the same function earlier. Affects file
6910 silcd/packet_send.c and all channel packet sending functions.
6912 * In USERS reply, res_argv[i] are not allocated, the table
6913 is allocated. Thus changed that free the table, not its
6916 * In server's whois_check and identify_check if the client is
6917 locally connected do not send any WHOIS commands - they are not
6920 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6922 * Fixed some minor bugs in client when sending WHOIS command. The
6923 arguments was in wrong order.
6925 * Removed statis function add_to_channel from server in
6926 silcd/command.c that was previously used with the joining but
6929 * Tested USERS command in router environment successfully with two
6930 routers, two servers and two clients.
6932 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6934 * Reorganized the USERS command and command reply in client library
6935 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6936 When the command is given by user we register a pending command
6937 callback that will reprocess the command after the reply has been
6938 received from the server. When reprocessing the packet we then
6939 display the information. Thus, the USERS information is displayed
6940 now in the command callback instead of in the command reply
6941 callback. The processing of the command is same as previously
6942 when server has sent the command reply in the JOINing process.
6944 * Added to USERS command in silcd/command_reply.c to join the client,
6945 we didn't use to know about, to the channel after we've created
6946 a client entry for it. Also, for clienet we did know already still
6947 check whether it is on the channel or not and add it if not.
6949 * Removed silc_server_command_join_notify as the function and its
6952 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6954 * Changed the client's pending command handling to the same as the
6955 server's pending command handling. It is also now possible to
6956 execute command reply functions from other command reply
6957 function as the function callbacks for commands and command
6958 replies are one and same. The pending commands are not static
6959 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6960 in client connection context. Thus, pending commands are server
6961 connection specific as it is convenient.
6963 Changed the function silc_client_command_pending and
6964 silc_client_command_pending_del and added new function
6965 silc_client_command_pending_check. Removed the
6966 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6969 * Added cmd_ident, current command identifier, to the client
6970 connection context in lib/silcclient/client.h to keep track on
6971 command identifiers used in command sending. Client's command reply
6972 function handling now supports the mandatory command identifiers.
6974 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6975 funtions in client to fully support pending command callbacks.
6977 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6978 as one of the arguments to the application in the command reply
6981 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6982 before first releasing SILC but came back. Now it is removed again
6983 and should come back nomore. The FORWARDED flag was used only
6984 by the JOINing procedure by forwarding the command packet to router.
6985 Now, the JOINing procedure has been changed to more generic (due
6986 to various router environment issues) and FORWARDED is not needed
6987 anymore for anything. The protocol specification is yet to be
6990 Now, removed silc_server_packet_forward from server and the flag
6991 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6993 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6995 * Renamed NAMES command to USERS command. The NAMES was named that
6996 due to historical reasons. Now it is renamed. Also, rewrote
6997 parts of the USERS command. The nickname list is not sent anymore
6998 by the server. Only Client ID and mode lists are sent in the USERS
6999 command. Changed this also to the protocol specification.
7001 The client now resolves the names and stuff after it receives
7002 the USERS list from the server when joining to the channel.
7004 * WHOIS and IDENTIFY commands has been changed to support multiple
7005 Client ID's per command. One can now search for multiple users
7006 in the network by sending only one WHOIS or IDENTIFY command.
7007 Changed the code and the protocol specifications.
7009 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7010 uses silc_server_command_whois_parse to parse the request. */
7012 * If normal server, do not parse the WHOIS and IDENTIFY requests
7013 before sending it to the router. Saves some time.
7015 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7017 * Fixed JOIN command on client library. Wrong number of arguments
7018 used to crash the client.
7020 * Added silc_server_channel_has_global function to check whether
7021 channel has global users or not.
7023 * Added silc_server_channel_has_local function to check whether channel
7024 has locally connected clients on the channel.
7026 * The silc_server_remove_from_one_channel now checks whether the
7027 channel has global users or not after given client was removed from
7028 the channel. It also checks whether the channel has local clients
7029 on the channel anymore. If it does not have then the channel entry
7030 is removed as it is not needed anymore.
7032 * The silc_server_notify now checks on JOIN notify whether the joining
7033 client is one of locally connected or global. If it is global then
7034 the channel has now global users on the channel and that is marked
7035 to the channel entry. Also, it now saves the global client to
7036 global list who is joining and JOINs it to the channel. This is
7037 for normal server, that is.
7039 Changed silc_server_send_notify_on_channel,
7040 silc_server_packet_relay_to_channel and
7041 silc_server_packet_send_to_channel check if we are normal server
7042 and client has router set (ie. global client) do not send the
7043 message to that client, as it is already routed to our router.
7045 * Implemented LEAVE notify type handling in silc_server_notify
7048 * Tested LEAVE command in router environment successfully. Tested
7049 with two routers, two servers and two clients.
7053 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7055 * Implemented SIGNOFF notify type handling in silc_server_notify
7058 * silc_server_remove_id now removes the client entry from all channels
7059 it has joined and thusly sends SIGNOFF notify type.
7061 * Rewrote the NAMES list generation in server by removing two excess
7062 loops. The lists are created now inside one loop.
7064 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7066 * silc_server_remove_channel_user checks now also global list
7067 for channel and client.
7069 * silc_server_new_channel_user checks now both local and global
7070 list for channel and client. Fixed a bug in client id decoding.
7071 Used to decode wrong buffer.
7073 * silc_server_channel_message checks now both local and global
7074 list for channel entry.
7076 * Tested channel joining (hence JOIN) in router environment
7077 successfully. Tested with two routers, two servers and two
7080 * Tested channel message sending in router environment successfully.
7082 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7084 * Added silc_server_save_channel_key into server.[ch] to save the
7085 received channel key in Channel Key payload processing. It is
7086 also used in JOIN command reply handling.
7088 Equivalent function silc_client_save_channel_key added into
7089 client.[ch] into client library.
7091 * Changed JOIN command reply to send information whether the channel
7092 was created or not (is existing already) and the channel key
7093 payload. Changed protocol specs accordingly.
7095 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7096 the request was sent by ID and not by nickname. Crashed on
7099 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7101 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7102 now correctly save the received data.
7104 * silc_server_free_sock_user_data now notifies routers in the
7105 network about entities leaving the network.
7107 At the same time implemented functions silc_server_remove_id
7108 and silc_server_send_remove_id to receive and send REMOVE_ID
7109 packets. The packet is used to notify routers in the network
7110 about leaving entities. The ID removed will become invalid in
7113 * Added function silc_idlist_del_server into server. Removes and
7114 free's server entry from ID list.
7116 * silc_server_private_message function now checks, if we are router,
7117 that the destination ID really is valid ID, naturally.
7119 * In router when NEW_ID packet is received (for new client) the
7120 hash of the Client ID is saved in the ID Cache but the
7121 client->nickname is set to NULL, instead of putting the hash
7124 IDENTIFY command now also checks that client->nickname must be
7125 valid. If it is not if will request the data from the server who
7126 owns the client. Added new function
7127 silc_server_command_identify_check.
7129 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7130 to set the command to already allocated Command Payload.
7132 * Tested private message sending in router environment with two
7133 routers, two servers and two clients. Fixed minor bugs and now
7136 * Fixed segfault from client's NAMES command. Used to crash if
7139 * Forwarded packets must not be routed even if it is not destined
7140 to the receiver. Changed server code comply with this.
7142 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7144 * Added `require_reverse_mapping' boolean value to ServerParams
7145 structure. If TRUE (not default) the server will require that
7146 the connecting host has fully qualified domain name.
7148 If the reverse mapping is not required and hostname could not be
7149 found the IP address is used as hostname.
7151 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7153 * Implemented version string checking to both client and server.
7154 The check is incomplete currently due to the abnormal version
7155 strings used in development version of SILC.
7157 * Changed all command functions in server to use the new
7160 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7162 * Changed char *data to unsigned char *data in ID Cache system to
7163 support binary data as ID Cache data. Changed code to support
7164 binary data in lib/silccore/idcache.c.
7166 * Renamed silc_server_packet_relay_command_reply to
7167 silc_server_command_reply as it is normal packet receiving
7168 function. Rewrote the function to accept command replys for
7169 servers and not only for clients.
7171 * Mark remote router always as registered server if we are connecting
7172 to it. Otherwise, commands sent by the router to us are ignored.
7174 * All ID List find routines now returns the ID Cache Entry pointer
7175 as well if requested.
7177 * WHOIS command works now in router environment, tested with two
7178 routers, two servers and two clients.
7180 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7181 in router environment (as it is almost equivalent to WHOIS) but
7182 hasn't been tested thoroughly. Added new functions:
7184 silc_server_command_identify_parse
7185 silc_server_command_identify_send_reply
7186 silc_server_command_identify_from_client
7187 silc_server_command_identify_from_server
7189 * Disabled route cache adding because adding two different ID's with
7190 same IP replaces the old cache entry thus giving wrong route.
7191 The entry->router->connection is always the fastest route anyway
7192 so route cache may not be needed. Of course, new routes maybe
7193 established after receiving the ID when the entry->router->connection
7194 might not be anymore the most optimal.
7196 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7198 * Add route cache for received ID for fast routing.
7200 * Added silc_server_packet_route to route received packet on router
7201 that is not destined to us.
7203 * Renamed silc_server_get_route to silc_server_route_get.
7205 * Added id_string and id_string_len fields into SilcServer to
7206 include encoded ServerID for fast comparing without excess
7207 encoding of the ID's.
7209 * Cleaned up WHOIS command on server side. Added following static
7212 silc_server_command_whois_parse
7213 silc_server_command_whois_check
7214 silc_server_command_whois_send_reply
7215 silc_server_command_whois_from_client
7216 silc_server_command_whois_from_server
7218 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7219 arguments in command replies. All command functions should be
7220 updated to use this macro.
7222 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7224 * Minor typo fixes on command reply handling on server.
7226 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7228 * Added silc_server_command_add_to_channel internal routine to add
7229 the client to the channel after router has created the channel and
7230 sent command reply to the server.
7232 * Added generic silc_server_send_command to send any command from
7235 * Use static buffer with ID rendering instead of duplicating data.
7237 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7239 * Fixed a channel user mode bug when joining to a channel server gave
7240 everybody channel founder rights, oops.
7242 * We mark ourselves as the router of the incoming server connection
7243 if we are router ourselves. This way we can check in some packet
7244 sending functions whether it is locally connected server. For
7245 incoming router connections we put NULL.
7247 * For router sending packets locally means now always sending the
7248 packet cell wide; to local clients and local servers. For normal
7249 server sending packet locally means sending it to only local
7252 * Fixed the JOIN command to really work in router environment. If the
7253 channel is created it is always created by the router. Router is
7254 also responsible of making the initial joining to the channel,
7255 sending JOIN notify to the sending server and distributing
7256 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7257 does not exist server doesn't do anything else but forward the
7258 command to the router which performs everything.
7260 * Added silc_server_send_channel_key function to send the Channel Key
7263 * Added silc_server_create_channel_key to create new channel key. The
7264 channel key is now re-generated everytime someone joins or leaves
7265 a channel, as protocol dictates. Note: channel->key_len is the
7268 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7270 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7271 packet_receive.[ch] to separate packet sending and receiving
7272 routines. The server.[ch] now includes everything else including
7273 actual packet processing (writing and reading data) and other
7276 Renamed silc_server_private_message_send_internal to
7277 silc_server_send_private_message. The routine is still though
7278 used only to relay private messages as server does not send
7279 private messages itself.
7281 Renamed silc_server_new_channel to silc_server_create_new_channel
7282 and added new function sicl_server_new_channel that handles the
7283 incoming New Channel packet. Added also new sending function
7284 silc_server_send_new_channel to send New Channel Payload.
7286 * Added new function silc_server_notify to process incoming notify
7287 packet to the server/router. Server may then relay the notify
7288 to clients if needed.
7290 * Added new function silc_server_new_channel_user to process incoming
7291 New Channel User packet. Router will redistribute the packet and
7292 send JOIN notify to its local clients and locally connected servers
7293 if needed. Normal server will send JOIN notify to its local client
7294 on same channel when received this packet. Added also corresponding
7295 sending function silc_server_send_new_channel_user to sent the
7298 * Added boolean route argument to send_notif_to_channel and
7299 packet_send_to_channel functions to attempt to route the packet
7300 if it is TRUE and send only locally if it is FALSE.
7302 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7304 * silc_server_replace_id now broadcasts the received replace ID
7305 packet if it is not broadcast packet already. The router must
7306 broadcast to inform other routers about changed ID.
7308 * Added backpointer to server's router into SilcServer context in
7309 silcd/server_internal.h.
7311 * Fixed silc_server_packet_broadcast to send correct broadcast
7314 * The channel key is now distributed to the local client as soon
7315 as it is received from the router (in router environment) so that
7316 no other packet may be sent for the channel until client has
7319 * silc_server_remove_channel_user now broadcasts the received
7320 Remove Channel User packet if it is not broadcast packet already.
7321 The router must broadcast to inform other routers about removed
7324 * Added users field into SilcPacketContext that is a reference count
7325 of the context. One can increase the reference count by calling
7326 silc_packet_context_dup which is now changed to just increase the
7327 reference count instead of duplicating the data. The reference
7328 count is decresed by calling silc_packet_context_free that will
7329 free the data after the reference count hits zero.
7331 For now on the packet context and everything allocated into it
7332 (including the raw packet from network) must be freed by calling
7333 the new silc_packet_context_free function. Added also new function
7334 silc_packet_context_alloc that must be used now to allocate the
7335 context. This also means that if a routine is asynchronous from
7336 silc_[client/server]_packet_parse_type the packet context must
7337 be duplicated by calling silc_packet_context_dup. Otherwise it
7338 gets free'd after silc_[client/server]_packet_parse_type returns.
7339 Also, one must remember that if packet is duplicated then its
7340 reference count must be decresed by calling the free function as
7341 many times as it was duplicated.
7343 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7344 from both client and server.
7346 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7348 * Made joining to a channel working in router environment.
7350 * Cleaned up JOIN command on server side and create function
7351 silc_server_command_join_channel internal routine to make the
7354 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7356 * Changed silc_command_pending list to SilcDList. Also, added
7357 `ident' field to SilcServerCommandPending structure to identify
7358 the reply and to call correct callback.
7360 Added silc_server_command_pending_check function to replace the
7361 corresnponding macro. The silc_command_pending list is not
7364 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7365 to set identifier to previously allocated Command Payload. It
7366 is used to set identifier for command when resending Command
7369 * Added silc_command_payload_encode_payload to encode Command
7370 Payload buffer from SilcCommandPayload structure.
7372 * Added silc_argument_payload_encode_payload to encode Argument
7373 payload buffer from SilcArgumentPayload structure.
7375 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7377 * Changed WHOIS command to support router connection on server side.
7378 The whois request is always sent to router unless the server is
7379 standalone server. After server has received the reply from the
7380 router will it send the reply to the client.
7382 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7383 broadcast received broadcast packet. The function is used only
7384 by router. The broadcast packet is always sent to the router's
7387 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7388 render given ID to printable string, for log files for example.
7390 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7392 * Made basic router to router connections working. At least they
7393 can now connect to each other but nothing really works the way
7394 they are supposed - yet.
7396 * Added new initiator token to RouterConnection configuration
7397 file in silcd/serverconfig.[ch]. It is used to tell whether we
7398 are the initiator to the remote router or whether we'll expect
7399 the other end to connect.
7401 * Moved registering of listener task to silc_server_init, hence
7402 the server starts listenning as soon as it is run, even if it
7403 does not have connections to other routers. Let's see how well
7406 * Changed default connection retry timeouts for more suitable in
7409 * Removed cipher and such arguments from silc_idlist_add_client
7410 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7411 Added new function silc_idlist_add_data to add the keys and stuff
7414 * Added SilcIDListData structure and added it to SilcClientEntry
7415 and SilcServerEntry as their first field in the structure. This
7416 way we can explicitly cast the ID entries to the SilcIDListData
7417 structure and get common data for the entries. In past, we had
7418 to first check what type of connection it is and then cast it to
7419 correct ID entry type. Now, we can directly cast the opaque
7420 pointer to the SilcIDListData (no matter what ID entry it actually
7421 is) and get the data needed.
7423 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7425 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7426 in some circumstances even if threre were timeout tasks, though not
7427 IO tasks, but tasks anyway. Now fixed.
7429 * Defined SilcServerConnection structure to hold connection specific
7430 stuff about directly connected servers and routers. The definition
7431 is currently in silcd/server_internal.h. I thought about having
7432 a bit more important role fro this struct but for now it is used
7433 only when connecting to other server (or router actually).
7435 * Added connecting retry support in server when connecting to
7436 router(s). The retry feature implement exponential backoff
7437 algorithm. Also, added SilcServerParams structure to hold default
7438 parameters for server. For now, it include these retry settings
7439 and are hard coded. After server is moded to be as Silc Server
7440 Library this structure will be more important.
7442 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7444 * Changed client librarys channel->clients table to SilcList and
7445 changed code accordingly.
7447 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7449 * Changed client's channel table to SilcList and changed code
7450 accordingly. Also changed SilcChannelClientEntry to include back-
7451 pointer to the channel so that client entry can use that structure
7452 as list as well and we have fast cross-reference to the channel.
7453 This change dramatically decreased the complexity of channel
7454 handling with client entry and vice versa (removed one extra
7455 loop when searching for channel entry from many functions).
7457 * Changed server->sim from table to SilcDList and changed code
7460 * NAMES command can now be used from user interface. It will show
7461 the user list on the channel, neatly.
7463 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7464 Code now saves realname of the user if it becomes available.
7466 * Renamed configure.in to configure.in.pre and made ./prepare
7467 script to automatically add correct version string to
7468 configure.in which it creates from configure.in.pre.
7470 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7472 * NAMES command reply now shows users mode with the nickname when
7475 * Moved silc_client_ch[u]mode[_char] functions from
7476 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7477 place sucks, they are utility functions and should be in some
7480 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7482 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7485 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7489 * Added TRQ (efficient deque and list library) into lib/trq. This is
7490 a very good list library that is currently used in the SILC. Defined
7491 SilcList API over the library because I didn't like the API very
7492 much. See lib/trq/silclist.h for the API and examples of how to
7493 use the API. Fixed various places in the code to use the new
7494 SilcList API. The SilcList is meant for lists that has a structure
7495 already defined as a list. It is not suitable to add just some
7496 context to the list (in TRQ, the context is the list actually).
7498 So, I defined SilcDList that can be used for the purpose where
7499 predefined list structure does not exit. This can be used as
7500 such list. Now some context just can be added to the SilcDList.
7501 Currently this list is not used in the SILC just yet, though there
7502 are a lot places where this can replace dynamically allocated
7503 tables and I will fix these places, later, to use SilcDList.
7504 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7505 and use TRQ internally).
7507 Also fixed some annoying warning messages that the original TRQ
7508 code generated. Also minor changes to TRQ's Makefile.in.
7510 * Added support for querying by Client ID to both WHOIS and
7511 IDENTIFY commands into server, as required by the protocol.
7513 * Removed method function pointers from SilcBuffer structure. They
7514 weren't used to anything and just increased the context size for
7515 no good reason. This change also made silc_buffer_alloc and
7516 silc_buffer_free functions inline functions.
7518 * Disabled command flooding detection support until it's fixed so
7519 that it accepts commands in but does not execute them more than once
7522 * Added silc_net_localhost(), to return local hostname, into
7523 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7524 that must be initialized before calling silc_client_init.
7526 * Added new function: silc_server_send_notify_on_channels to send
7527 notify messages to all channels client has joined. It is assured
7528 that the message is sent only once per client.
7530 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7531 lib/silcutil/silcutil.[ch] as silc_format function. The new
7532 function is generic and is used by server as well, not only by
7533 the logging routines.
7535 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7536 the provided version string was not acceptable. Added new function:
7537 silc_ske_check_version into lib/silcske/silcske.h. The function
7538 must be implemented by the application (client or server) and it
7539 does not reside in the SKE library. The function checks the version
7540 string remote end sent.
7542 * Added back pointers (to opaque context and to SilcSocketConnection)
7543 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7545 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7546 duplicate packet context structure.
7548 * Changed `notify' client operation to send same arguments as client
7549 receives from server except for ID's. ID's are mapped to correct
7550 ID entry and that is returned. Also, if channel entry is not sent
7551 by server but the notify is for channel the channel entry is sent
7552 to application (otherwise application doesn't know that it is for
7553 channel (library gets it from packet's Destination ID)).
7555 * Added silc_client_remove_from_channels into client library to
7556 remove a client from all channels it has joined to. Used when
7557 received SIGNOFF notify from server. Added also new function
7558 silc_client_replace_from_channels to replace old ID entry with
7559 new ID entry on all channels. Used when received NICK_CHANGE
7562 * Fixed ID Cache list handling in silc_idlist_get_client in
7563 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7564 to get (or query) client by ID.
7566 * Updated TODO list.
7568 * Added connection authentication status message defined by the
7569 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7570 support for these into the code in client and server side.
7572 * Added generic function silc_client_send_command to send any command
7573 with variable argument list. Application should use this function
7574 to send commands if the command functions provided by the library
7575 does not suite for the application's user interface needs.
7577 * Added new `failure' client operation. Application is notified about
7578 received failure packet if client is executing a protocol. In this
7579 case the protocol's execution has failed.
7581 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7582 is required by the protocol.
7584 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7585 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7588 * Added status flag to SilcSKE object to indicate realtime status
7589 of the SKE protocol.
7591 * Application receives now exactly same command reply arguments as
7592 the library receives from server. However, if ID is received the
7593 corresponding ID entry is returned to the application (eg. Client
7594 ID is mapped to correct SilcClientEntry entry and that is returned).
7595 Changed command_reply client operation due to this change.
7597 * Changed all ID's in commands and in command replys as ID Payloads.
7598 Change affected both client and server side codes.
7600 All ID's sent in SILC network (with execption of ID's in SILC
7601 Packet header) are sent in ID Payload to support variable length
7604 * Server now notifies nick changes and notifies all clients on
7605 the channels about the new nickname (about the new Client ID,
7608 * Implemented CMODE command to change channel modes. Supports all
7609 channel modes defined by the protocol specs except ban and invite
7610 lists. (Also, private channel key mode is supported but support for
7611 setting private channel key in client is missing, thus, this mode
7612 has no effect on client side (except that server requires that the
7613 client uses private channel key and normal channel traffic does not
7616 Also, invite mode works per se, but INVITE command does not work
7617 yet correctly, so you can set channel as invite only channel but
7618 inviting clients to the channel does not work (it is yet to be
7619 thought what's the best way to do it).
7621 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7622 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7623 Implemented CUMODE command to change user's mode on the channel.
7624 Supports all modes defined by the protocol specs.
7626 * Added NAMES command reply to return users modes on the channel.
7628 * Removed unnecessary and slow ciphers from lib/silccrypt.
7630 * Set SO_KEEPALIVE option to connection sockets by default.
7632 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7634 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7635 redefined the Notify Payload into protocol specs.
7637 * Added silc_id_payload_parse_id to get ID directly from raw
7640 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7642 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7643 accept searching by Client ID as well.
7645 * Added support for LEAVE and SIGNOFF notify types in client library.
7647 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7648 to parse ID Payload from raw data.
7650 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7652 * Added flags parameter into silc_ske_assemble_security_properties
7653 function in lib/silcske/silcske.[ch].
7655 * Changed notify client operation to fit better for notify messages
7656 sent by server. The notify payload received from server is now
7657 passed to the application (after parsing it to SilcNotifyPayload).
7658 It is application's responsibility to retrieve the arguments
7659 from the payload and show the message the way it wants. The message
7660 sent by server is implementation specific.
7662 * Changed public keys to comply with the protocol specification.
7663 Old public keys are not supported anymore and are not compatible.
7665 * Removed nickname from Channel Payload as the latest draft removed
7666 it. The client must resolve the nickname from the NAMES command
7667 reply received when it joined the channel.
7669 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7671 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7673 * Fixed some errors in protocol specification drafts.
7675 * Created lib/silccore/silcnotify.c to implement Notify Payload
7676 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7677 generic payloads described by protocol specifications. The file
7678 includes implementations for ID Payload and Argument Payload.
7680 * Changed Command Payload implementation to use the new Argument
7681 Payload. Changed command_xxxx_payload to command_payload_xxxx
7682 to comply with SILC coding conventions.
7684 * Added suppport for Argument Payload handling in Notify Payload
7685 implementation as protocol requires it. Added the new support
7686 into server and client lib as well.
7688 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7690 * Added support for multiple nicknames on same channel. [n] is
7691 added locally to the nickname if there are more than one same
7692 nicknames on the channel.
7694 * Server now sends all nicknames that matched WHOIS request.
7695 Client also shows the list received from server.
7697 * Added TOPIC command to client side. User can now set and show
7698 current topic on channel.
7700 * Added MOTD command to client and server. Also, server sends the
7701 motd when client connects to the server.
7703 * Changed version strings to comply ISO 8601.
7705 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7707 * Fixed protocol error handling in client library. It should now
7708 cope even if the SKE fails for some reason.
7710 * Made new protocol specification drafts for submitting to IETF.
7712 * Implemented TOPIC command to server in silcd/command.c.
7714 * Added two new notify types into lib/silccore/silcnotify.h:
7715 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7716 notify nickname change and topic setting/change on a channel.
7718 * API change of command_reply operation in client library. The
7719 application gets now the status type received from server as well.
7721 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7723 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7725 * Cras fixed and optimized the packet handling even further and
7726 it should work now. Minor change to the prototype of function
7727 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7729 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7731 * Added new function into lib/silcutil/silcschedule.[ch]:
7732 silc_schedule_with_fd to select() a specified fd. The function
7733 returns after timeout expires or data arrives or goes. The
7734 function is used by packet routines to wait that all data is
7735 received from network.
7737 * Fixed data reading from network in lib/silccore/silcpacket.c.
7738 The code now assures that all data is read from the fd and then
7739 continues packet processing. This was a bug fix since the code
7740 used to drop some data in some circumstances.
7742 * Added new function into lib/silcclient/client.[ch]:
7743 silc_client_start_key_exchange to start key exchange after
7744 connection has been established to server. The code internally
7745 now uses this funtion but its main purpose was to provide it
7746 for applications that perform their own connecting. After
7747 application has created a connection it merely calls this
7748 function to start the key exchange between client and server.
7749 The library takes care of everything else after that.
7751 Updated also lib/silcclient/README to explain the usage of
7754 * Do not send to application information that connection has
7755 been established. Application gets notified it by connect
7758 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7760 * Applied cras's patch to add silc_schedule_one function. The
7761 function runs scheduler once and returns.
7763 * Fixed the scheduler after cras messed it up. The timeout
7764 handling works now as it's supposed to work.
7766 * Added into lib/silccore/ silcnotify.h to include notify
7767 message types support. Changed silc_server_send_notify*
7768 functions, in server.[ch], to support those new notify types.
7769 Added the support for the notify types into client library,
7770 as well. Added new notify client operation into ops.h in
7773 * Changed silc_server_packet_send_to_channel to send normal
7774 packets instead of just channel message packets. The function
7775 is now used to send the notify packets to channels. It is not
7776 used to send channel message packets anymore, as server never
7779 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7780 va_arg()s as it seems to require it nowadays. I guess, if SILC
7781 is compiled with older va_arg() the new code should work anyway.
7783 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7785 * Splitted core library. Core library (lib/silccore) includes
7786 now only SILC protocol specific core (and common) components.
7787 Created new utility library (lib/silcutil) that includes more
7788 generic purpose stuff. The stuff for util library was taken
7789 from the old core library. This was minor and easy split.
7791 * Created SILC Client Library (lib/silcclient) that includes
7792 implementation of the SILC client without user interface. This
7793 was major move from silc/ directory. The code has been changed
7794 so that it is transparent towards the user interface. The
7795 silc/ directory includes now the same user interface as before
7796 and it uses the new client library. Read lib/silcclient/README.
7797 Basicly, the client library performs everything else related
7798 to SILC except user interface handling. Also, configuration
7799 files are considered to be part of user interface and library
7800 does not handle them.
7802 This change also changed a lot of structures, function naming etc.
7803 Most important change was that SilcClientWindow object was
7804 renamed to SilcClientConnection in the client library. Created
7805 also new file lib/silcclient/ops.h. Also added new files
7806 silc/local_command.[ch] and silc/client_ops.[ch].
7808 All these changes were made to make it easier for user interface
7809 designers to create what ever user interface for the SILC client
7812 It is also expected that the server will be moved to lib
7813 directory as well and SILC Server Library will be created;
7814 sometimes in the future.
7816 * Removed Local commands from lib/silccore/silccommand.h as
7817 they are application specific and new client library does not
7818 handle any of those anymore.
7820 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7821 old client implementation in silc/.
7823 * Added support for callback functions in SILC_LOG_* macros.
7824 Application can now set its own callbacks that will be called
7825 instead of using the default functions that will always print
7826 the debug messages to stderr (or stdout). Also, debugging can
7827 now be disabled by setting silc_debug to FALSE and re-enabled by
7828 setting it to TRUE. Note, that logging will still work even
7829 if debugging is disabled.
7831 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7832 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7833 silc_log_reset_debug_callbacks.
7835 * To enable debugging in silc client one must give now -d
7836 option on command line.
7838 * Changed silc_schedule_init to automatically allocate task queues
7839 if they are not allocated before calling it.
7841 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7843 * Added GMP 3.1 into math library.
7845 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7847 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7848 a channel in SILC network. The packet is used by servers and
7849 routers to notify other routers that user has left a channel.
7850 This little feature was missing until now. Added the feature
7851 to protocol specification as well.
7853 Added functions: silc_server_send_remove_channel_user and
7854 silc_server_remove_channel_user into server.[ch].
7856 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7857 lib/silccore/silcpacket.h. However, they are not implemented
7860 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7862 * Fixed joining to a channel and sending channel messages
7863 between server and router. The channel message sending should
7864 now work inside a cell.
7866 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7868 * Fixed the private message sending between server and router.
7869 The private message sending should now work inside a cell.
7871 * Added silc_server_replace_id into server.[ch] to replace
7872 existing ID in the SILC network.
7874 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7875 and silc_idlist_replace_server_id into idlist.[ch] in server.
7877 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7879 * Fixed the server to server connections. Server can again now
7880 connect to router. Router to router connections probably does
7883 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7885 * Added dynamic protocol registering support. Now protocols can
7886 registered and unregistered on the fly. Patch by cras.
7888 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7890 * Added lib/contrib directory to hold routines that some platforms
7891 don't have but are needed by SILC.
7893 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7894 into lin/contrib to provide getopt() and getopt_long() for
7895 those who don't have it.
7897 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7899 * Added AWAY command to client. When away message is set and
7900 client receives a private message packet the client automatically
7901 replies to the sender with the away message.
7903 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7904 bug seemed to be the cause of recent problems when compiling
7907 * Added version detection support to SKE protocol specification
7908 and added the new changes to the SKE implementation as well.
7909 There were other minor changes in the SKE protocol as well.
7911 Many changes in lib/silcske/silcske.[ch] and in
7912 lib/silcske/payload.[ch].
7914 * Added ^U functionality, clear input line. Patch from cras.
7916 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7918 * Mainly small bugfixes on core library. Fixed some debugging
7919 logging and buffer overflow in silclog.c.
7921 * Updated config.sub and config.guess on the distribution tree.
7923 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7925 * Added command lagging support in server. Client may execute
7926 commands now only once in two seconds.
7928 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7930 * Optimized packet reception. MAC computation and checking is now
7931 also more optimized. A lot previously duplicated code is now
7932 used as generic by both client and server.
7934 * Fixed key pair generation in clientutil.c
7936 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7938 * Added into lib/silccore/silcbufutil.[ch] new function;
7939 silc_buffer_realloc.
7941 * Moved generic packet sending/encryption functions to
7942 lib/silccore/silcpacket.[ch] from client and server. Some
7943 rewriting of the functions.
7945 * Moved all generic packet reception/decryption functions to
7946 lib/silccore/silcpacket.[ch] from client and server. The
7947 packet processing is now much cleaner in both client and server.
7948 These were major changes in both client and server.
7950 * Created many common functions in server to do packet sending.
7951 Previously code were duplicated a lot, this has been removed
7954 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7956 * Rewrote major parts of the ID cache system. Don't know
7957 whether it is better now or not but at least the API is more
7960 * Major rewrite on ID cache stuff on client because of the ID
7961 cache API changes. Added idlist.c to client.
7963 * Also major rewrite on ID cache stuff on server as well.
7964 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7965 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7966 in hand, instead they are all put into the ID cache system now.
7967 All server_idlist_* routines uses ID cache now instead of
7968 traversing its own lists (those lists does not exist anymore).
7969 SilcIDList though still exists. Also, SilcXXXEntry's are
7972 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7974 * Finally made the SKE implementation compliant to the protocol
7975 specification. All mp integers are now binary encoded as
7976 opposed being HEX encoded.
7978 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7981 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7982 functions: silc_[encode/decode]_pem. Also added function
7983 silc_encode_pem_file to PEM encode with newlines ('\n') for
7986 * SILC public keys are now encoded either PEM or binary. Same
7987 option is for private keys as well. By default private keys
7988 are binary encoded and public keys PEM encoded. Silly HEX
7989 encoding were removed.
7991 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7992 function to create fingerprints.
7994 * Fixed a bug in SHA1; does not change the original data anymore.
7996 * Partly implemented INFO command on client and server side.
7997 Fixed CLEAR command. Changes to SERVER command; show current
7998 server(s) when giving command without arguments. Added
7999 VERSION command to client.
8001 * Added check to server that unregistered connections cannot
8002 execute commands (unless it is specificly allowed).
8004 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8006 * Fixed screen refresh.
8008 * Fixed channel joining bug from client. On some circumstances
8009 client tried to join to a channel it had already joined.
8011 * Added public key verification process into client's protocol.c.
8012 The client now verifies the public key from user and saves
8013 it into ~./silc/serverkeys/ directory.
8015 Added into: clientutil.[ch]: silc_client_verify_server_key.
8017 * Changed SKE protocol's silc_ske_initiator_finish function
8018 to accept callback function that verifies the received public
8019 key. Removed old silc_ske_verify_public_key function.
8021 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8023 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8024 silc_pkcs_private_key[_data]_set.
8026 * Made the password and public authentication more cleaner in
8027 server's protocol.c.
8029 * Removed historic and obsolete protocol `channel_auth' from
8030 both client and server.
8032 * Removed wrong way of sending command status messages from
8033 server to client in server's command.c. The old way violated
8034 protocol specification.
8036 Changes to silccore/silccommand.[ch]: removed
8037 silc_command_encode_status_payload -> not needed anymore,
8038 changed silc_command_encode_payload_va to accept extra
8039 argument on variable argument list. The argument type must
8040 now be provided to the function. Also, added new function:
8041 silc_command_encode_reply_payload_va which is same as
8042 normal command_encode_payload_va except command status type
8043 is provided as extra argument.
8045 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8047 * Added ~./silc directory handling. The directory includes the
8048 public and private keys for the client.
8050 Added silc_client_check_silc_dir, silc_client_create_identifier
8051 and silc_client_load_keys.
8053 * Implemented SILC protocol compliant public key. Added public
8054 and private key saving to and loading from files.
8056 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8057 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8058 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8059 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8060 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8062 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8063 silc_pkcs_load_[public/private]_key.
8065 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8067 * Added silc_server_get_route (route.[ch]) to get connection
8068 data for the fastest route for given ID.
8070 * Implemented INVITE command on client and server. The command
8071 were re-defined in the SILC Protocol Specification and the
8072 implementation now complies with the specification.
8074 * Implemented PING command on client and server.
8076 * Implemented NAMES command on client and server. The server side
8077 supports currently only normal server not router server yet.
8078 Some changes to NAMES definition in SILC protocol specification.
8080 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8082 * Implemented LEAVE command on client and server.
8084 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8085 again. This change was made to the protocol as well. Server
8086 should not violate the protocol specification anymore.
8088 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8090 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8091 was tested. SOCKS4 was not but should work anyway.
