1 Tue Apr 16 09:34:40 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Defined that channel message to unknown Channel ID must
4 cause SILC_NOTIFY_TYPE_ERROR notify message to the sender.
5 Updated the protocol specs and the code in server. The
6 affected file is silcd/packet_receive.c.
8 Mon Apr 15 19:57:57 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
10 * Added new notify type SILC_NOTIFY_TYPE_ERROR and specified
11 that it is used to send error notifys if error occurs during
12 some SILC packet processing, except commands. The error
13 types are same as for command reply types. Defined that
14 if private message is sent to unknown Client ID the error
15 is sent in SILC_NOTIFY_TYPE_ERROR instead of command reply.
16 Updated the protocol specs and code. Affected files are
17 lib/silccore/silcnotify.h, added lib/silccore/silcstatus.h,
18 lib/silcclient/client_notify.c, silcd/packet_receive.c,
19 and irssi/src/silc/core/client_ops.c. Renamed the
20 SilcCommandStatus to SilcStatus.
22 * Defined the use of extra WHOIS attributes in WHOIS command.
23 The <Requested Attributes> (defined in a separate document)
24 can be used to request additional information about user
25 not returned by standard WHOIS command. Defined that server
26 can send WHOIS command directly to client. Client provides
27 the requested attributes to the server. Updated the protocol
28 specs. Protocol TODO #4. Implementation is not done yet
31 * Renamed function silc_client_command_status_message to
32 silc_client_status_message. Affected files are

51 options to the server. Affected files silcd/serverconfig.[ch],
52 silcd/command.c and silcd/packet_receive.c.
54 Fri Apr 12 20:09:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
56 * Added resolve_cmd_ident field to the SilcClientEntry structure
57 too so that if the entry is for example being resolved so
58 another command may attach to the same pending command reply
59 without requiring to resolve the same entry again. Added
60 support for adding multiple pending commands for one
61 command idenfier. Affected files lib/silcclient/command.[ch],
62 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
64 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
66 * Defined that server receives WHOIS command reply for private
67 and secret channels too. Updated protocol specs and the
68 code in server. Affected file silcd/command.c.
70 * Defined <channel user mode list> argument to WHOIS command
71 reply for returning user modes on the channels. The
72 channel list now doesn't include the user mode anymore but the
73 actual channel mode. Updated protocol specs and the code in
74 client and server. Affected files are silcd/command_reply.c,
75 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
76 and lib/silcclient/command_reply.c.
78 * Save the channels list in WHOIS command reply in normal server
79 so that WHOIS always shows joined channels also in normal
80 server and not just on router. Affected file is
81 silcd/command_reply.c.
83 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

92 not provided then the command merely returns the current mode
93 mask to the client. Updated protocol specs and the server.
94 Affected file is silcd/command.c.
96 * Added SILC session detachment/resuming support. It is possible
97 to detach by closing the network connection and then re-connect
98 and resume to the old client session. Added DETACHED user
99 mode that server will set for detached client. Added new
100 packet RESUME_CLIENT which is used to perform the resuming
101 process. Added DETACH command. Updated the protocol specs,
102 core library, client and server. Protocol TODO #22. Very
103 many affected files around the tree.
105 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
107 * Changed the CMODE's mode mask argument to be optional. If
108 not provided then the command merely returns the current mode
109 mask to the client. Updated protocol specs and the server.
110 Affected file is silcd/command.c.
112 * Changed the Killer's Client ID in KILLED notify to be just
113 any ID payload since router server is allowed to kill as well.
114 Updated protocol specs, client libary and server. Affected
115 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
116 and irssi/src/silc/core/client_ops.c.
118 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
120 * Added new user modes ANONYMOUS for special anonymous servers
121 that may set the mode for client, and BLOCK_PRIVMSG which
122 client may set to block incoming private messages unless the
123 Private Message Key flag is set (using private keys to protect
124 private messages). Updated protocol specs and code in client
125 and server and core library. Protocol TODO #23. Affected
126 files are lib/silccore/silcmode.h, silcd/server.[ch],
127 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,

131 may set to itself to tell server not send channel messages.
132 Other packets such as channel key packets are still sent.
133 Protocol TODO #23. Updated the protocol specs, client and
134 server. Affected files are lib/silccore/silcmode.h,
135 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
136 lib/silcutil/silcutil.c, silcd/command.c, and
139 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
141 * Redefined the Status Payload to include now two 8 bit fields,
142 instead of one 16 bit field. This now makes it possible to
143 send list of errors. Updated the protocol specs and the code
144 in core library, client library and server. Protocol TODO #1.
145 Affected files are lib/silccore/silccommand.[ch],
146 lib/silcclient/command_reply.[ch], silcd/command.c,
147 silcd/command_reply.c and silcd/packet_receive.[ch].
149 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
151 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
152 must be handled by the application and should tell the application
153 that an error message was already printed, and it should print the
154 config coords (line, filename, ...). Affected files are
155 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
157 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
158 server config parsing code more readable.

173 lib/silccore/silcmode.h, irssi/src/silc/core/client_ops.c,
174 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
176 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
178 * Added STATS command to the protocol after all, to return
179 various statistical information about the network. It can
180 be used by clients to retrieve statistical information, and
181 servers may use it to to fetch cell and network wide
182 statistics from router. Updated the protocol specs and
183 implemented it to the server. Protocol TODO #16.
184 Affected files are lib/silccore/silccommand, silcd/command.[ch],
185 silcd/command_reply.[ch].
187 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
189 * The LIST command reply in client libary now adds new channel
190 entry if the returned channel doesn't exist yet in cache,
191 and returns the channel entry to the application in the
192 command_reply client operation. Affected file is
193 lib/silcclient/command_reply.c.
195 * Changed the channel message payload's MAC generation to
196 include the IV in the MAC as well. This way all relevant
197 parts of the channel message payload are authenticated also
198 with the channel message MAC (and not only by packet MAC).
199 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
200 Affected file is lib/silccore/silcchannel.c.
202 * Fixed the SKE to save the remote version, since the
203 silc_ske_parse_version mistakenly checked wrong version,
204 after it replaced the start payload. Affected files are
205 lib/silcske/silcske.[ch].
207 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
209 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for
210 string utility functions. Added there also new functions
211 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
212 Affected files lib/silcutil/silcstrutil.[ch].
214 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
215 files are lib/silcutil/silcstrutil.[ch].
217 * Defined that the security property fields in SKE SHOULD be
218 UTF-8 encoded, defined that version string MUST be US-ASCII
219 encoded, defined that passphrases sent in connection
220 authentication protocol MUST be UTF-8 encoded. Implemented
221 these to the client and server. Defined also that other
222 passphrases sent in the protocol MUST be UTF-8 encoded.
223 Affected files are lib/silcske/silcske.c,
224 lib/silcclient/protocol.c, silcd/protocol.c,
225 silcd/serverconfig.c, and lib/silccore/silcauth.c.
227 * Changed the silc_client_close_connection interface to not
228 need the SilcSocketConnection which should not be visible
229 to application. Affected files are lib/silcclient/client.c
230 and lib/silcclient/silcclient.h.
232 * Rewrote the text for Private Message Key Payload in the
233 protocol specification. Protocol TODO #11.
235 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
237 * Upgraded the protocol version to 1.1, updated protocol specs
240 * Added the nickname as new argument to NICK_CHANGE notify and

251 The killer's client entry is now returned to application in
252 the `notify' client operation.
254 * Fixed the Max Argument fields that had too large value set
255 in the protocol specs. Protocol TODO #14.
257 * Added the LEAVE command reply to return the ID of parted
258 channel. Updated protocol specs and implemented it to the
259 client and server. Protocol TODO #15. Affected files are
260 silcd/command.c, lib/silcclient/command_reply.c. The channel
261 entry is now returned to application in the `command_reply'
264 * Rewrote the version SKE version checking in client libary
265 and in server to use the silc_parse_version_string. Affected
266 files are lib/silcclient/protocol.c, silcd/protocol.c.
268 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
269 commands that was missing it, and updated protocol specs and
270 the server implementation. Protocol TODO #10. The affected
271 file is silcd/command.c.
273 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
274 generic reply to a generic request (REQUEST flag), and
275 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
276 way. A draft-riikonen-silc-flags-payloads-00.txt is written
277 to define the payload for DATA flag. Added the flags to
278 the implementation. Protocol TODO #9. Affected file is
279 lib/silccore/silcchannel.h.
281 Changed the client library to return the message length
282 to application as well in the channel_message and private_message
283 client operations. Affected files are
284 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
285 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
286 and lib/silcclient/client_ops_example.c.
288 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
289 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
290 the channel. Updated protocol specs and impelemented this
291 to client and server. Protocol TODO #6. Affected files are
292 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,
293 lib/silcclient/client_channel.c, lib/silccore/silcmode.h.
295 Added new options m and M to CMODE command in Irssi SILC
296 client to set these modes.
298 * Deprecated all administrative commands from SILC protocol
299 since they are highly implementation specific commands.
300 Updated protocol specs. Moved the old commands in
301 implementations to private range of command types. Affected
302 files are silcd/command.c, lib/silcclient/command.c and
303 lib/silcclient/command_reply.c. Protocol TODO #8.
305 * Fixed a bug in server where sending unknown command crashes
306 the server. Affected file silcd/command.c.
308 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
310 * Added SILC_PROTOCOLVERSION macro to check protocol version
311 of a socket connection. The affected file is
312 lib/silcutil/silcsockconn.h.
314 * Added better error logging in rekey protocol. Affected file
317 * Do not check public key types in SKE during rekey. Affected
318 file lib/silcske/payload.c.
320 * Fixed the rekey protocol with PFS, which was totally broken.
321 Affected file silcd/protocol.c.
323 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
325 * Some client implementations quit network by doing first LEAVE
326 and then immediately SIGNOFF (like Bombyx). We now do check
327 after a short time after LEAVE notify and check whether the
328 client is still valid after LEAVE, and if not we remove it from
329 cache. Affected file is lib/silcclient/client_notify.c.
331 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
333 * Merged version 1.1.4 of zlib. Even if it not currently in use,
334 it's good not to have security holes here.
336 * Fixed a negative refcount situtuation for the config context.
337 Affected file is silcd/serverconfig.c.
339 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
341 * ROBOdoc documented lib/silcutil/silcutil.h.
343 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
345 * Optimized even more the SilcPacketContext structure. Now
346 totally saved 16 bytes of memory per context after optimization.
347 Affected files are lib/silccore/silcpacket.[ch].
349 * Made strict checks for valid SILC IDs. Affected file is
350 lib/silccore/silcid.c.
352 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>
354 * Changed the object argument for silc_cipher_register,
355 silc_hash_register, silc_hmac_register and silc_pkcs_register
356 to const. Affected files are lib/silccrypt/silccipher.[ch],
357 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
359 * Changed the silc_get_username and silc_get_real_name to
360 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
362 * Fixed the Irssi SILC Client to use the silc_get_username and
363 silc_get_real_name insted of glib routines since the glib
364 routines only corrupt stack. Fixes the Irssi SILC to work in
365 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
367 * Fixed the Irssi to not use g_get_home_dir since it crashes
368 or returns garbage on cygwin and corrupts stack. Added function
369 get_home_dir to Irssi routines. Affected files are
370 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
372 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
374 * Made some structure optimizations. SFTP memory FS MemFSEntry
375 entry structure. Optimized SilcTask structure. Optimized
376 SilcPacketContext structure.
378 Affected files lib/silcsftp/sftp_fs_memory.c,
379 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
381 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
383 * And yet again reverted back the config thing since Johnny
384 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
387 * Fixed memory leaks from config object. Affected files are
388 silcd/serverconfig.[ch].
390 * Added support for adding new connections to the server in rehash.
391 After rehash they take effect.
393 Added support for changing the maximum allowed connections in
394 rehash. The number can grow but going smaller is not supported.
396 Added function silc_server_num_sockets_by_remote to the
397 silcd/server_util.[ch].
399 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
401 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
403 * Added preliminary checking during config parsing for a valid
404 public/private key and removed further checks in the code.
405 Affected files are silcd/serverconfig.[ch], server.c.
407 * Moved functions silc_server_drop() and silc_server_daemonise()
408 from server.c to silcd.c since they are stricly related to
409 the application activity.
411 * Reverted a small part of the automatic ref/unref since
412 it caused a double unref in some situations. Affected
413 files are silcd/silcd.[ch], server.c, serverconfig.c.
415 * Added some .cvsignore files in the lib directory.
417 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
419 * Fixed silc_net_gethostbyaddr to correctly resolve by
420 address. Affected file lib/silcutil/silcnet.c.
422 * Fixed the notify relaying to client. The HMAC to be used
423 with relayed packets ws wrong and caused decryption failure
424 at the client end. Affected file is silcd/packet_receive.c.
426 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
428 * Created new branch silc_protocol_1_0_branch.
430 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
432 * Changed the silc_server_config_* routines to be SilcServer
433 independent. They are now officially application specific code
434 and not part of generic server implementation. Affected files
435 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
437 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
439 * Added automatic referencing of config context in the
440 silc_server_config_alloc, and automatic unreferencing in the
441 silc_server_config_destroy. Affected files are
442 silcd/serverconfig.[ch], silcd/silcd.c.
444 * Fixed the silc_log_quick handling in the logging routines.
445 It didn't log quickly when it was TRUE. Affected file is
446 lib/silcutil/silclog.c. Also the flush delay was set even
447 if it was 0 in config file. Affected file is
448 silcd/serverconfig.c.
450 * Added support for changing key pair of the server in rehash.
451 Affected file silcd/server.c.
453 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
455 * Fixed the TOPIC_SET notify to not cras. It changed the topic
456 too early, before getting the channel entry. Affected file
457 is silcd/packet_receive.c.
459 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
461 * Added functions silc_server_config_[ref/unref], these are used
462 to prevent that the config object is destroyed.
464 No longer directly affect global variables silc_log_quick and
465 silc_log_delay, they are first cached inside the config object
466 and then applied with silc_server_config_setlogfiles().
468 silc_server_config_set_defaults() is now internal to
469 serverconfig.c, there are no reasons to show this internal stuff
472 Affected files are silcd/serverconfig.[ch].
474 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
475 fprintf's to stderr, since some code may be executed again after
476 the server went into the background. Affected files are
479 * Added rehash support. Added function silc_server_rehash() that
480 will perform all the basic tasks of the rehashing procedure.
482 * Added command line option `-x, --hexdump'. This will enable the
483 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
484 The option `--hexdump' implies `--debug'.
486 * Fixed a bad bug in the logging APIs (silcutil library) where
487 the application would crash after calling silc_log_reset_all().
489 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
491 * Fixed the KICKED notify handling in client library to
492 correctly remove the channel and all entries from the
493 channel when I was kicked. This bug crashed the client.
495 Fixed yet another but in KICKED notify handling to remove
496 the kicked client correctly from the channel.
498 Affected file is lib/silcclient/client_notify.c.
500 * Fixed a minor bug in looking up correct client entry
501 in KICKED notify in server. Affected file is
502 silcd/packet_receive.c.
504 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
505 sources correctly to distribution. Fixes --with-gmp option.
507 * Removed the manual rehashing from ID Cache, and changed it
508 to use the SILC Hash Table's auto rehash feature. Affected
509 file is lib/silccore/silcidcache.c.
511 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
513 * Fixed a bug in the silc_client_nickname_format function that
514 handles the multiple same nickname formatting. Two clients
515 with same nickname caused problems after the first one left
516 and rejoined. It didn't format the nickname correctly.
517 Affected file is lib/silcclient/idlist.c.
519 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
521 * Don't change the topic if olod topic is same as new one.
522 Affected file is silcd/packet_receive.c.

526 * Added cross-reference support to the SILC Documentation
527 generator. All types across all HTML files are now cross-
528 referenced. Affected files util/robodoc/generator.c and
529 scripts/silcdoc/silcdoc.
531 * Added file lib/silcutil/silctypes.h to include all the
532 arithmetic type definitions and some macros. Removed
533 includes/bitmove.h and moved macros to silctypes.h.
535 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
537 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
539 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
541 * Added `type' argument to silc_id_payload_parse_id function which
542 now returns the type of the ID to the sent pointer. Affected
543 file is lib/silccore/silcid.[ch].
545 * Added check for CMODE_CHANGE notify type that mode change is
546 allowed by the sender. Affected file silcd/packet_receive.c.
548 * Added check for CUMODE_CHANGE notify type that mode change is
549 allowed by the sender. Affected file silcd/packet_receive.c.
550 Added the ID type as CUMODE_CHANGE notify type as argument
551 to the `notify' client operation. Affected files are
552 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
554 * Added function silc_client_add_server to the client library.
555 Added support for resolving also channel and server info when
556 received unknown entity in notify packet. Affected files are
557 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
559 * Added function silc_command_get_status to return the command
560 status from the command reply's argument payload. Affected files
561 are lib/silccore/silccommand.[ch].
563 * Added check for KICKED notify type that the kicking is
564 allowed by the client. Affected file silcd/packet_receive.c.
566 * Created function silc_get_input which can be used to get input
567 (echo on or off) from user on command line. Affected files are
568 lib/silcutil/silcutil.[ch].
570 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
572 * Optimized silc_server_packet_relay_to_channel function.
573 Added new function silc_channel_message_payload_encrypt which
574 can be called directly if channel message payload needs to
575 be encrypted and is already encoded (no need to call _encode
576 function). Packet relaying is now done by router without any
577 extra memory allocations. Affected files are
578 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
581 * Fixed the INVITE notify handling. It took wrong arguments
582 as invite list and invite delete. Affected file is
583 silcd/packet_receive.c.
585 * Added check for TOPIC_SET notify type that the topic change is
586 allowed by the client. Affected file silcd/packet_receive.c.
588 * Added check for INVITE notify type that inviting is allowed by
589 the client. Affected file silcd/packet_receive.c.
591 * Changed the silc_server_client_on_channel to return the
592 SilcChannelClientEntry as well. Moved the function
593 silc_server_check_cmode_rights to server_util.[ch].
594 Affected files are silcd/server_util.[ch], silcd/command.c.
596 * Added function silc_server_check_umode_rights to check whether
597 changing client's user mode is allowed. Added check for
598 UMODE_CHANGE notify type that the umode change is allowed
599 by the client. Affected files are silcd/server_util.[ch],
600 silcd/packet_receive.c and silcd/command.c.
602 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
604 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
605 ID length. It ignored that ID can be IPv6 based as well.
606 Affected file lib/silccore/silcpacket.h.
608 * Fixed the silc_id_id2str and silc_id_str2id to take the
609 IPv6 address offset's into consideration. Affecte file is
610 lib/silccore/silcid.c.
612 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
614 * Fixed the internal Unix scheduler functions to check for
615 NULL context they may receive. The affected file is
616 lib/silcutil/unix/silcunixschedule.c.
618 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
620 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
621 can specify different directory with --home command line
622 parameter. Affected files irssi/src/silc/core/client_ops.c,
625 * SILC-specific commands aren't now executed if the active server
626 isn't of SILC-type, so there won't be problems with having
627 IRC and SILC protocol support in same client. Affected files
628 irssi/src/silc/core/silc-channels.c, silc-servers.c,
631 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
633 * Improved the signal support in SILC Schedule. Added new
634 function silc_schedule_signal_call which is used by application
635 to mark a signal to be called. It is now safe to perform
636 any kind of tasks in signal callbacks since it is guaranteed
637 that the application specified signal callback is called
638 after the signal is over. Affected files are
639 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
641 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
643 * Added `name' field to SilcChannelPrivateKey to represent
644 application given name for the key. Moved also the context from
645 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
646 Added the `name' argument also to the function
647 silc_client_add_channel_private_key.
649 Added function silc_client_current_channel_private_key to set the
650 current channel private key in use.
652 Added "change" command to KEY command which can be used to change
653 the current channel private key. Bound the command also to
656 Also affected files lib/silcclient/client_channel.c,
657 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
659 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
661 * Added silc_rng_get_byte_fast function in to the
662 lib/silccrypt/silcrng.[ch].
664 * Changed the interface of silc_packet_assemble and the
665 silc_packet_send_prepare. If silc_packet_assmble is now
666 called the application does not call silc_packet_send_prepare
667 because the library will call it automatically. These
668 interfaces now also return a reference to the outgoing buffer
669 which includes the assembled packet, which the application can
670 use to encrypt the packet.
672 Affected files are lib/silccore/silcpacket.[ch],
673 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
674 silcd/packet_send.c, server_backup.c and packet_receive.c.
676 * Fixed a packet sending bug on very high load, where outgoing
677 packet queue wasn't handled correctly and packets got corrupted.
678 Affected files are lib/silcutil/*/silc*sockconn.c,
679 lib/silcclient/client.c and silcd/server.c.
681 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
683 * Added macro SILC_PACKET_DATALEN which can be used during
684 packet assembling to check whether the data to be added to
685 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
686 len is truncated until it fits it.
688 Added checks for maximum length of channel message payload and
689 private message payload also.
691 Added checks for maximum packet length in server and in
694 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
695 lib/silcclient/client.c, lib/silccore/silcchannel.c and
696 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
697 lib/silcclient/client_prvmsg.c.
699 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
701 * Added silc_server_packet_queue_purge call to the
702 silc_server_disconnect_remote to assure that all data in the
703 queue before disconnecting is sent to the network. Affected
706 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
708 * Added the deleting of server's own ID cache entry to the
709 silc_server_free function. Free also everything else that
710 has been allocated in silc_server_init. The affected file
713 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
715 * Added functions silc_parse_version_string, silc_version_to_num,
716 and silc_ske_parse_version to parse SILC protocol style version
717 strings. Affected files lib/silcutil/silcutil.[ch] and
718 lib/silcske/silcske.[ch].
720 * Added new configuration params: version_protocol, version_software
721 and version_software_vendor to specify what version the remote
722 host must at least be to be able to connect to server. The vendor
723 string can be regex matched too. Added new function
724 silc_server_connection_allowed to check maximum number of allowed
725 connections, and allowed versions for incoming connections.
726 Affected files are silcd/server.c, server_util.[ch] and
729 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
731 * Added preliminary support for signals in scheduler. The
732 signals we care about are now blocked always when the scheduler
733 is locked. This way we can synchronise the use of signal with
734 scheduler. It is guaranteed that when signal occurs the scheduler
735 is not locked, and thus new tasks can be safely added to the
738 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
739 to silc_schedule_internal_init and silc_schedule_internal_uninit.
740 Added new platform specific routines
741 silc_schedule_internal_signals_[un]block and
742 silc_schedule_internal_signal_[un]register.
744 Added new functions to SILC Schedule API:
745 silc_schedule_signal_[un]register. Each signal that application
746 is going to use should be registered to the scheduler.
748 Affected files are lib/silcutil/silcschedule.[ch],
749 lib/silcutil/*/silc*schedule.c.
751 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
753 * Check for unauthenticated client and server in the
754 silc_server_new_client and silc_server_new_server functions.
755 Affected file silcd/packet_receive.c.
757 * Added function silc_string_is_ascii to check whether given
758 string is 7-bit ASCII string. Affected files are
759 lib/silcutil/silcutil.[ch].
761 * Added function silc_id_is_valid_server_id into the
762 silcd/serverid.c and added checking for valid Server ID's in
763 silc_server_new_server. The Server ID must always be based
764 on the server's public IP address.
766 * Added logging of DISCONNECT packet message in the server.
767 Affected file silcd/server.c.
769 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
771 * Changed all library interfaces that use Global RNG to also
772 accept SilcRng as argument. Affected files are
773 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
774 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
775 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
776 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
779 * Added function silc_pkcs_generate_key to the
780 lib/silccrypt/silcpkcs.[ch] for applications so that they
781 don't need to do pkcs->pkcs->init calls anymore.
783 * Remove SilcSocketConnection from the SFTP API since it really
784 wasn't needed there. The application has the information
785 saved in its contexts anyway and the SFTP layer doesn't need
786 know about it. Affected files lib/silcsft/silcsftp.h and
787 lib/silcsftp/sftp_[server/client].c.
789 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
790 The SilcSimContext is not SilcSim.
792 * Fixed possible buffer overflows in silc_id_render in the
793 lib/silcutil/silcutil.c.
795 * On EPOC the global crypto module lists are not used at all
796 in the crypto library. Added support for using the constant
797 algorithm list on EPOC. Affected files are
798 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
801 * Fixed the handling of third parameter of KICKED notify, since
802 it was mistakenly updated to SILC Protocol 1.0 even though it
803 is to be included in 1.1. Since it is not in 1.0 it is not
804 mandatory, and this fix now handles it only if it is provided,
805 and it is not error if it is not provided. Affected file
806 lib/silcclient/client_notify.c.
808 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
810 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
811 client. Affected file irssi/src/silc/core/client_ops.c.
813 * Merged with Irssi 0.8.4 from irssi.org CVS.
815 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
817 * Check for valid socket connection in client entries before
818 sending any messages. Fixes a crash, but doesn't fix some
819 other underlaying bug that is lurking there. Affected
820 file silcd/packet_send.c.
822 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
824 * $usermode, $cumode and $cumode_space expandos shouldn't do
825 anything with non-SILC server records. Affected file
826 irssi/src/silc/core/silc-expandos.c
828 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
830 * Fixed the silc_net_check_[host/local]_by_sock to support
831 IPv6 bound sockets as well. Now they can return IPv6 addresses
832 as well. Affected file lib/silcutil/silcnet.c.
834 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
835 Affected lib/silcutil/unix/silcunixnet.c.
837 * Fixed ID rendering (at least on some platforms, not NetBSD)
838 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
840 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
842 * Added silc_hash_public_key and silc_hash_public_key_compare
843 functions to be used with SilcHashTable. They can be used to
844 hash public keys and compare public keys in hash table. Affected
845 file lib/silcutil/silcutil.[ch].
847 * Added support for specifying multiple public keys for Client
848 connection section in server configuration file. This makes it
849 possible to accept multiple public keys from same host, or to
850 make a section that accepts any incoming host, and have the
851 accepted public keys listed in the section.
853 Added functions silc_sever_[find/get]_public_key, added the
854 support for this actually to all connection sections but only
855 the Client section is currently allowed to specify multiple
858 Affected files are silcd/server.c, server_internal.h,
859 command.c, protocol.c, server_util.[ch], packet_receive.c.
861 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
863 * Merged Irssi 0.8.2 from irssi.org CVS.
865 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
867 * If silc_debug is TRUE, also output standard logging messages
868 to stderr with the debug output.
870 Made silc_log_reset_all() flushing all channels before returning.
871 Also fixed some documentation typos.
873 Affected files are lib/silcutil/silclog.[ch].
875 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
877 * Fixed the server to check correctly the amount of connections
878 from single host, by checking also the type of the connection.
879 Fixed also the comparison of number of connections and number
880 of allowed connections. Affected files are silcd/server.c,
883 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
885 * Fixed the USERS command reply to save the user's mode on the
886 channel as well. Fixed JOIN command reply to check whether a
887 client is on channel already and not join it twice. Affected
888 file lib/silcclient/command_reply.c.
890 * Added new file silc-expandos.c into irssi/silc/core/ to return
891 various stuff for various signal for the statusbar etc. updating.
892 Now Irssi SILC client prints channel user modes etc. on the
895 * The user mode (like server/router operator changes) is now shown
896 on the Irssi SILC client's statusbar. The affected files are
897 irssi/src/silc/core/client_ops.c, silc-expandos.c.
899 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
901 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
902 to SILC_SCHEDULE_[UN]LOCK macros.
904 * Added more error printing to logs in server code. Affected
905 files silcd/server.c and silcd/protocol.c.
907 * Fixed -S option parsing in Irssi SILC Client. Affected file
908 irssi/src/silc/core/silc-core.c.
910 * Added silc_buffer_alloc_size function. Affected file is
911 lib/silcutil/silcbuffer.h.
913 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
915 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
916 constants. Affected files in
917 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
920 * Changed the internal SFTP Memory FS table to const. Affected
921 file lib/silcsftp/sftp_fs_memory.c.
923 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
925 * Fixed the buffer formatting and unformatting routines to
926 check the size of 64 bits types with sizeof(). Affected
927 file is lib/silcutil/silcbuffmt.c.
929 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
931 * Removed 0.6.x backwards support.
933 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
935 * Changed all integer type names:
936 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
937 to avoid collisions with other libraries using same type names
940 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
942 * Added `prefer_ipv6' argument to the functions
943 silc_net_gethostbyname[_async]. If it is TRUE it will return
944 IPv6 address over IPv4. If FALSE IPv4 address is returned
945 even if IPv6 address was found. Affected files
946 lib/silcutil/silcnet.[ch].
948 * Added support silc_net_create_connection[_async] to fallback
949 to IPv4 address if IPv6 address could not be used (like if
950 it doesn't work on a specific system). Affected file in
951 lib/silcutil/unix/silcunixnet.c.
953 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
955 * Added silc_schedule_reinit function to do the enlarging
956 of the max tasks handling capabilities of the scheduler.
957 Affected files lib/silcutil/silcschedule.[ch].
959 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
961 * Added automatic extern "C" { ... } for C++ compilers so the
962 application does not need to define them. Affected file
963 includes/silcincludes.h.
965 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
966 old name went against naming convention. Applications now
967 include "silcclient.h" instead of "clientlibincludes.h".
968 Removed includes/clientlibincludes.h, it is redundant now.
970 * Renamed includes/version.h to silcversion.h.
972 * Added really preliminary support for OS/2 into the util
973 library. Only thread & mutex API is implemented, others
974 are still to be implemented. Created the lib/silcutil/os2/
975 directory. Created also file includes/silcos2.h.
977 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
979 * Added preliminary BeOS support into the util library.
980 Created lib/silcutil/beos/, and implemented all the needed
981 functions to support SILC on BeOS. Created also file
984 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
986 * Added proper initializations to silc's irssi code, so it's
987 now possible to load it as module. Affected files
988 irssi/src/silc/core/silc-core.c,
989 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
991 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
993 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
996 * Fixed the silcdoc document generator to correct generate
997 docs from all kinds of filenames. Affected files are
998 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
1000 * ROBOdoc documented lib/silcutil/silcmemory.h.
1001 Added also new function silc_memdup.
1003 * Removed lib/silcutil/silcbufutil.h and moved those routines
1004 to the lib/silcutil/silcbuffer.h.
1006 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1008 * Added `user_count' to the SilcChannelEntry which now tells the
1009 number of users on the channel. The user count is now saved
1010 in normal server of global channels as well. Affected files
1011 silcd/server.c, idlist.h, packet_receive.c and command.c.
1013 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
1014 include file utility functions.
1016 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
1017 instead of calling directly OS routines.
1019 * Fixed NICK change printing in Irssi SILC Client. Fixed
1020 KICKED notify printing in Irssi SILC Client. Affected file
1021 irssi/src/silc/core/client_ops.c.
1023 * Fixed a NICK change bug in client library, to not recreate the
1024 client_entry->channels hash table everytime nick is changed.
1025 Affected file lib/silcclient/client.c.
1027 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1029 * ROBOdoc documented the lib/silcske/silcske.h, and improved
1030 the SKE interface a bit.
1032 * Fixed padding problem in PKCS#1. The padding was not actually
1033 random since the random number generator was used incorrectly.
1034 This security bug affects only when encrypting with PKCS#1, and
1035 it is not currently used at all in SILC. SILC only use signing
1036 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
1038 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1048 * Added following new config file settings:
1049 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1050 key_exchange_timeout, conn_auth_timeout, connections_max,
1053 Implemented all the new config settings handling in the server.
1055 Optimized the use of SKE Mutual flag usage. Use it only
1056 if connection authentication protocol is not based in public
1059 Renamed all SilcServerConfigSection* to SilcServerConfig*
1060 to have a bit shorter names.
1062 Affected files silcd/serverconfig.[ch], server.[ch], and
1065 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

1091 Affected files are silcd/serverconfig.[ch].
1093 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1095 * Fixed command line parameter handling. All SILC initialization
1096 is now done in silc_core_init() which also fixes autoconnecting
1099 Affected files irssi/src/silc/core/silc-core.c,
1100 irssi/src/fe-text/silc.c.
1102 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1104 * Added new configuration options and blocks:
1105 keepalive_secs, reconnect_count, reconnect_interval,
1106 reconnect_interval_max, reconnect_keep_trying and
1107 require_reverser_lookup. Added ConnectionParam block, and
1108 implemented the connection parameters when connecting as
1109 initiator and when accepting connections as responder.

1117 algorithm parts and created new file silcalgs.conf, that
1118 is now included from the example_silcd.conf.in.
1120 * Optimized the silc_server_connect_to_router_second to take
1121 the connection configuration object from the SilcServerConnection
1122 object instead of finding it during the connecting phase.
1123 Added the configuration object to SilcServerConnection struct.
1124 Affected files silcd/server_internal.h, server.c.
1126 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1128 * Add the client on channel after it was resolved at the
1129 channel message receiving, and it was not already on the
1130 channel. Affected file lib/silcclient/client_channel.c.
1132 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1134 * Fixed the public key authentication to allocate always the

1146 * Added new Passphrase and Publickey authentication methods to
1147 config file, allowing both public key and passphrase based
1148 authentication to be set at the same time.
1150 Added `prefer_passphrase_auth' setting in config file which
1151 can be used to set to prefer passwd auth if both passwd and
1152 public key is set. If not set, public key is preferred.
1153 This has effect only when being initiator (responder will try
1156 Added support for authentication with passphrase and public key
1157 at the same time. The passphrase is tried first always since
1158 it is faster to check.
1160 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1162 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1164 * Merged the new SILC Config library, with the server parsing
1165 support. Read the header file silcconfig.h or the toolkit
1166 documentation for the news. Affected files are

1189 Payload. Affected file lib/silccore/silcchannel.c.
1191 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1192 as header filenames.
1194 * Removed lib/silcclient/README and created HTML file
1195 lib/silcclient/silcclient_using.html, which is now included
1196 as part of Toolkit documentation.
1198 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1200 * Fixed CUMODE_CHANGE notify handling to change the mode of
1201 correct client. Affected file lib/silcclient/client_notify.c.
1203 * Make silc_rng_alloc fail if it cannot allocate the sha1
1204 hash algorithm. Affected file lib/silccrypt/silcrng.c.

1208 * Fixed the file transfer's key agreement payload to include
1209 zero port also if the hostname is NULL because it could not
1212 Call file transfer monitor callback now also if error occurs
1213 during key agreement protocol.
1215 Changed the silc_client_file_send interface to return the
1216 SilcClientFileError instead of session id. The session ID
1217 is returned into pointer provided as argument.
1219 Check that the file exists locally before sending the
1220 file transfer request at all.
1222 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1224 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1225 error than can occur while key agreement protocol. Affected
1226 file lib/silcclient/silcapi.h.
1228 * Fixed the event_mode CMODE handler to not crash when mode
1229 is changed and +k mode is set in the channel. Affected file
1230 irssi/src/silc/core/silc-channels.c.
1232 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1233 SILC_LOG_WARNING to give out Warning and not Error. Affected
1234 file lib/silcutil/silclog.c.
1236 * Fixed the channel message payload decryption in the function
1237 silc_channel_message_payload_decrypt to not modify the original
1238 buffer before it is verified that the message decrypted
1239 correctly. Otherwise, next time it is called with correct
1240 channel key it won't encrypt since the payload is corrupted.
1241 Affected file lib/silccore/silcchannel.c.
1243 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1253 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1255 * Fixed a bug in hash table internal routine for traversing
1256 the table with foreach callback. The current entry may
1257 become invalid in the callback but it was referenced after
1258 the callback returned.
1260 Do not allow auto rehashing of hash table during the
1261 silc_hash_table_foreach operation, for same reasons as it is
1262 not allowed for SilcHashTableList. Affected files are
1263 lib/silcutil/silchashtable.[ch].
1265 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1267 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1268 Win32 DLL. extern's in header files are now declared with
1271 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1273 * Fixed private message handling. It used some old code that
1274 caused the client to crash. Affecte file is
1275 lib/silcclient/client_prvmsg.c.
1277 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1279 * Added function silc_client_add_channel,
1280 silc_client_replace_channel_id, and removed functions
1281 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1282 from client library.
1284 * Added cross reference of the joined channels to the
1285 SilcClientEntry, and changed the SilcChannelEntry's
1286 users list to SilcHashTable. The affected files are
1287 lib/silcclient/idlist.[ch].
1289 * Fixed a bug in hash table tarversing. While the hash table
1290 is traversed with SilcHashTableList the table must not be
1291 rehashed. It is now guaranteed that auto rehashable tables
1292 are not rehashed while tarversing the list. Also defined that
1293 silc_hash_table_rehash must not be called while tarversing
1294 the table. Added function silc_hash_table_list_reset that must
1295 be called after the tarversing is over. The affected files are
1296 lib/silcutil/silchashtable.[ch].
1298 * Changed all hash table traversing to call the new
1299 silc_hash_table_list_reset in server and in client library.
1301 * Added function silc_client_on_channel to return the
1302 SilcChannelUser entry if the specified client entry is joined
1303 on the specified channel. This is exported to application as
1304 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1306 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1308 * Fixed founder regaining problem with JOIN command on normal
1309 server. The notify for mode change must be sent always and
1310 not only if !cmd->pending. Affected file silcd/command.c.
1312 * Fixed the WHOWAS command's reply sending to support the
1313 lists correctly. Affected file silcd/command.c.
1315 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1317 * When sending JOIN command to router for processing the
1318 sender's old command identifier was not saved back to the
1319 sender's command context, fixed now. The affected file is
1322 * Create the key in JOIN command of the router did not return
1323 the channel key, added check for this. Affected file is
1326 * Fixed a channel ID update bug in JOIN command reply. Do
1327 not directly upgrade the ID but call the function
1328 silc_idlist_replace_channel_id if the ID was changed.
1329 Affected file silcd/command_reply.c.
1331 * Fixed memory leaks from command calling if it would fail.
1332 Affected file silcd/command.c.
1334 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1336 * Applied patches from cras:
1338 Memory leak fixes around libaries, irssi window resize fix,
1339 new silclist.h and silcdlist.h, all extern inline changed to
1342 * Removed dotconf from lib/dotconf, not needed anymore.
1344 * Removed TRQ from lib/trq, not needed anymore.
1346 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1347 with server connections. Later this will be configurable
1348 in config file after new config file is done. Affected file
1351 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1353 * Fixed a crash in server related to channel announcements.
1354 Affected file silcd/server.c.
1356 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1358 * Fixed memory leaks in silc_server_create_new_channel*
1359 functions. Affected file silcd/server.c.
1361 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1362 which ID was changed. This way the router will send the
1363 user list for the channel again, and server won't be in
1364 desync in some rare circumstances. Affected file is
1365 silcd/packet_receive.c.
1367 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1369 * Check for NULL socket pointer in the function
1370 silc_server_packet_send_to_channel_real. Affected file

1378 * Fixed some header addition to Toolkit distribution in
1379 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1381 * Added lib/silcclient/client_ops_example.h as an template
1382 file for application programmers to quickly start using
1383 the SilcClientOperation functions in their application.
1384 Updated the lib/silcclient/README as well to tell about this
1385 nice file made available.
1387 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1389 * Call silc_server_remove_from_channels when removing client
1390 entry when NO_SUCH_CLIENT_ID was received. Affected file
1391 is silcd/command_reply.c.
1393 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1395 * Added server & router operator statistics updating. Affected
1396 file silcd/packet_receive.c and silcd/command.c.
1398 * Fixed the SERVER_SIGNOFF notify handling on normal server
1399 not to save the history information for clients. Same was
1400 fixed earlier in remove_clients_by_server function, but not
1401 here. Affected file silcd/packet_receive.c.
1403 * Raised the default connection-retry count from 4 to 7 in
1404 server. Affected file silcd/server.h.
1406 * Cancel any possible reconnect timeouts when we start the
1407 key exchange. Affected file silcd/server.c.
1409 * Do not reconnect on connection failure when SCONNECT was
1410 given. Affected files silcd/server.[ch].
1412 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1414 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1416 * Fixed the NICK command to always give the unformatted
1417 nickname to the one giving the NICK command. If unformatted
1418 nickname is cached already it will be formatted and the
1419 local entry will always get the unformatted nickname.
1420 Affected file lib/silcclient/idlist.c.
1422 * Fixed some double frees from client library commands.
1423 Affected file is lib/silcclient/command.c.
1425 * Fixed CUMODE command in server to assure that no one can
1426 change founder's mode than the founder itself, there was a
1427 little bug. Affected file silcd/command.c.
1429 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1431 * Removed the SilcClientCommandDestructor from the client
1432 libary, it is not needed anymore. Affected files are
1433 lib/silcclient/silcapi.h, command[_reply].[ch],
1434 client_notify, idlist.c.
1436 * Fixed GETKEY command to first resolve client, and then
1437 resolve the server only if the client was not found, instead
1438 of resolving both at the same time. Affected file is
1439 lib/silcclient/command.c.
1441 * Added silc_client_start_key_exchange_cb and lookup the
1442 remote hostname and IP address before starting the key
1443 exchange with server. The affected file is
1444 lib/silcclient/client.c.
1446 * The server's public key is now saved using the IP address
1447 of the server and not the servername for the filename.
1448 The hostname public key filename is checked as an fall back
1449 method if the IP address based filename is not found.
1451 Fixed the GETKEY command to save the fetched server key
1452 in correct filename.
1454 Print the remote server's hostname now when new key is
1455 received during connection process. Affected file is
1456 irssi/src/silc/core/client_ops.c.
1458 * Return always our own public key to the client if it asks
1459 for it with GETKEY command. Affected file silcd/command.c.
1461 * Removed the use_auto_addr variable from default config
1462 file since it was in wrong section. Affected file is
1465 * Fixed TOPIC_CHANGE notification to not route it when it
1466 was sent using silc_server_send_notify_to_channel function.
1467 Affected file silcd/command.c.
1469 * Fixed silc_server_send_notify_kicked to send the kicker's
1470 Client ID also, it was missing. Affected files are
1471 silcd/command.c, silcd/packet_send.[ch].
1473 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1475 * Do not save client history information in SERVER_SIGNOFF.
1476 Fixes the bug in normal server that it does not detect
1477 the client becoming valid after the server becomes back
1478 online. Affected file silcd/server_util.c.
1480 * Added `sock_error' field into the SilcSocketConnection
1481 context. When error occurs during socket operation (read
1482 or write) the error is saved. Added also new function
1483 silc_socket_get_error to return human readable socket error
1484 message. Affected files are lib/silcutil/silcsockconn.[ch],
1485 lib/silcutil/unix/silcunixsockconn.c, and
1486 lib/silcutil/win32/silcwin32sockconn.c.
1488 * The server now prints the socket error message in the
1489 signoff for client. Affected file silcd/server.c.
1491 * Fixed the `created' channel information sending from router
1492 to server in JOIN command. Checks now whether the channel
1493 really was created or not and set it according that.
1495 Fixed the JOIN command to use the client entry's current
1496 ID during the joining procedure instead of the one it sent
1497 in the command (it is checked though), since it can change
1498 between the packet processing and command processing, and
1499 would just case unnecessary pain in the client end. Affected
1500 file silcd/command.c.
1502 * Fixed a channel key payload sending to use correct channel
1503 ID when the server was forced to change the channel's ID by
1504 router. Router sent the key payload with the old Channel ID.
1505 Affected file silcd/packet_receive.c.
1507 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1509 * Call silc_server_save_channel_key only if the key payload
1510 was provided in the JOIN command's command reply. Affected
1511 file silcd/command_reply.c.
1513 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1515 * Fixed silc_mp_sizeinbase to return the value correctly with
1516 MPI. Affected file lib/silcmath/mp_mpi.c.
1518 * Fixed the stop_server signal to correctly stop the scheduler
1519 and gracefully stop the server when SIGTERM or SIGINT signals
1520 are received. Affected file silcd/silcd.c.
1522 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1524 * Simple handling of TERM and HUP signals. Also added some log
1525 flushing call around. Affected file is
1528 * Fixed small bugs in silclog.c. Now buffering output will take
1529 effect after 10 seconds since startup: This will ensure that
1530 no important startup messages are lost. Also output redirection
1531 will preserve original format ([Date] [Type] message).
1532 Affected file is lib/silcutil/silclog.c.
1534 * Added two options to the config file, in the logging section:
1535 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1536 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1538 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1540 * Do not print the warning about log files not being initialized
1541 more than once to avoid excess logging. Affected file is
1542 lib/silcutil/silclog.c.
1544 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1545 the SIM copying in make install in Makefile.am.pre.
1547 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1549 * Rewritten silclog APIs. Globally interesting changes follows:
1550 silc_log_set_files() changed to silc_log_set_file().
1551 silc_log_set_callbacks() changed to silc_log_set_callback().
1552 ROBOdoc documented silclog header file.
1553 SilcLogCb now returns bool to wether inihibit the default
1554 handler or not (to keep the old behaviour return always TRUE).
1555 The new APIs should also fix the problem of the
1556 silcd_error.log file that was written in the current directory.
1559 Log files streams will remain opened after silc_log_set_file()
1560 call, means less CPU usage notably on high traffic servers.
1561 File streams are now full buffered, and flushed to the disk
1562 every 5 minutes, lesses HD activity and CPU usage.
1563 Messages can be redirected, allowing admins to configure
1564 one single logfile for all server messages.
1565 the silc_log_quick global variable to activate fast-logging.
1566 Affected files lib/silcutil/silclog.[ch]
1568 * Changed some code to conform new silclog APIs. Affected
1569 files are doc/example_silcd.conf.in, silcd/server.c
1570 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1573 * Fixed a memory leak that could occur in some situations.
1574 Affected file silcd/serverconfig.c.
1576 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1578 * Added the silc_client_del_client to remove the client from
1579 all channels as well. Affected file lib/silcclient/idlist.c.
1581 * Fixed the client library to correctly remove the client
1582 from all channels when the client entry is being destroyed.
1583 Affected file lib/silcclient/client_notify.c, command.c.
1585 * Added auto-nicking support to the client library. If the
1586 applicatio now sets client->nickname it will be sent to the
1587 server after connecting by the library. This way for example
1588 SILCNICK (or IRCNICK) environment variables will have effect
1589 and always change the nickname automatically to whatever
1590 it is wanted. Affected file lib/silcclient/client.[ch].
1592 * Renamed silc_server_command_bad_chars to the
1593 silc_server_name_bad_chars and moved it to the
1594 silcd/server_util.[ch]. Added also new function
1595 silc_server_name_modify_bad to return nickname that
1596 includes bad characters as new nickname without those
1597 bad characters. This check and modify is now used in
1598 silc_server_new_client when the username is initially set
1599 as nickname, so it must be checked to be valid nickname.
1600 Affected file silcd/packet_receive.c.
1602 * The nickname length is now taken from the packet for real
1603 and not trusted to strlen() since it clearly can return
1604 wrong length for nickname including bad characters. This
1605 also applies to channel names. Affected file silcd/command.c.
1607 * Removed the lib/silcsilm/modules directory. Modules are now
1608 compiled into the lib/silcsim. Fixed the copying of the
1609 modules to follow symbolic links in Makefile.am.pre.
1611 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1613 * Fixed silc_string_regexify list creation. Fixes bugs with
1614 BAN and INVITE commands in server. The affected file is
1615 lib/silcutil/unix/silcunixutil.c.
1617 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1619 * Removed the command destructor entirely from the server's
1620 command and command reply routines. It is not needed, and
1621 its usage was buggy and caused crashes. Affected files are
1622 silcd/command[_reply].[ch].
1624 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1626 * Cancel protocol and NULL sock->protocol if timeout
1627 occurred during protocol. Affected file silcd/server.c.
1629 * Cancel protocol timeouts always before calling the final
1630 callback, to assure that after final callback is called
1631 no other state will be called for the protocol anymore.
1632 Affected file silcd/protocol.c.
1634 * Print error log if incoming connection configuration could
1635 not be found. Affected file silcd/server.c.
1637 * Fixed JOIN command to correctly save the founder mode
1638 to the client on normal SILC server, when the channel
1639 was created by the router. Affected file silcd/command.c.
1641 * Fixed LIST command (hopefully) to send correct reply
1642 packets. Affected file silcd/command.c.
1644 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1646 * The silc_packet_receive_process now returns FALSE if the
1647 read data was invalid packet, and TRUE if it was ok.
1649 The server now checks that if unauthenticated connection
1650 sends data and its processing fails the server will close
1651 the connection since it could be a malicious flooder.
1653 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1655 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1657 * Make sure the warning about error opening a log file is
1658 printed only once and not everytime it fails (produces
1659 too much useless log). Affected file lib/silcutil/silclog.c.
1661 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1663 * Made the silc_server_daemonise() function more readable.
1664 Affected file silcd/server.c.
1666 * Pid file is now optional, the user may comment it out from
1667 the config file. Removed define SILC_SERVER_PID_FILE, we
1668 don't need a default any longer. Affected file
1669 configure.in.pre, lib/Makefile.am.pre.
1671 * Make some use of the pid file. The server now dies at startup
1672 if it detects a valid pid file on his path. The server would
1673 die anyway in this circumstance, because of the bind() failure.
1674 Affected file silcd/silcd.c.
1676 * No longer compiling lib/dotconf.
1678 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1680 * Fixed JOIN command parsing not to crash. Affected file
1681 lib/silcclient/command.c.
1683 * Fied the NICK_CHANGE notify to add the new client entry
1684 even it is resolved. This removes an <[unknown]> nick
1685 thingy bug in the client. Affected file is
1686 lib/silcclient/client_notify.c.
1688 * Do not try to allocate 0 bytes (efence does not like it)
1689 in lib/silccore/silccomand.c when encoding payload.
1691 * Do not take IRCNICK as nickname in Irssi SILC client since
1692 it is not possible to set nickname before hand connecting
1693 the server (TODO has an entry about adding auto-nicking
1696 * Changed the silc_server_command_pending to check whether
1697 there already exists an pending entry with the specified
1698 command, command identifier and pending callback. This is
1699 to fix IDENTIFY and WHOIS related crashes that may register
1700 multiple pending commands with same identifier. Affected
1701 file silcd/command.c.
1703 * Fixed the server to reconnect to the router even if it
1704 was already reconnecting and EOF was received. This to
1705 fix a possibility that the server wouldn't ever try to
1706 auto-reconnect to the router. Affected file silcd/server.c.
1708 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1710 * Fixed the server's password authentication to use the
1711 length of the locally saved password, and not the one
1712 sent in the packet. Affected file silcd/protocol.c.
1714 * Fixed same password authentication problem in the
1715 Authentication Payload handling routines in
1716 lib/silccore/silcauth.c.
1718 * Yet another password authentication problem fixed with
1719 channel password handling in silcd/command.c.
1721 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1723 * If first character of string in silc_parse_userfqdn is '@'
1724 then do not parse it. Affected file is
1725 lib/silcutil/silcutil.c.
1727 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1729 * Fixed minor bug in IDENTIFY command reply sending, which
1730 caused various weird problems during JOIN when it was
1731 resolving names for users. Affected file silcd/command.c.
1733 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1735 * Fixed the IDENTIFY command reply sending to chech better valid
1736 clients. It was possible to send incomplete list of replies.
1737 Affected file silcd/command.c.
1739 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1741 * Added silc_client_command[s]_[un]register functions now to
1742 dynamically register the commands in client library. Removed
1743 the static table of commands. This allows the client library
1744 to call commands without causing the application to know about
1745 what commands library has called.
1747 Removed the INFO command reply kludge to detect when the command
1748 was called by library. Now library use its own command reply
1749 function for INFO command.
1751 Added function silc_client_command_call to call a command.
1752 Application can use it to call command, not access the structure
1755 Now all commands that are sent by the client library (not
1756 explicitly sent by application) use own command reply functions.
1758 Affected files around lib/silcclient/ and in
1759 irssi/src/silc/core/.
1761 * Fixed the WHOIS command reply sending to chech better valid
1762 clients. It was possible to send incomplete list of replies.
1764 Fixed the WHOIS and IDENTIFY to send the request to router
1765 if normal server did not do it and did not find any results.
1767 Affected file silcd/command.c.
1769 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1771 * Moved the internal data from SilcClient context into its
1772 own file, not accesible to application. Affected files
1773 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1774 and other files in client library.
1776 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1778 * Added doc/examples installation target in Makefile.am.pre.
1781 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1783 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1784 commands the found client entry will be removed from the
1785 cache, after notifying application about the error. Affected
1786 file lib/silcclient/command_reply.c.
1788 * Changed the /MSG to check for exact nickname user gave, and
1789 not let `nick' match `nick@host' if it is only one found. Now,
1790 user must type the exact nickname (like nick@host2) even if
1791 there are no more than one same nicks found. This is to avoid
1792 a possibility of sending nickname to wrong nickname since
1793 `nick' could match `nick@host'. Affected file is
1794 irssi/src/core/silc-servers.c.
1796 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1798 * Do not print "you are now server operator" or similar when
1799 giving /away command. Affected files are
1800 irssi/src/silc/core/client_ops.c, silc-servers.h.
1802 * Made the silc_server_command_pending_error_check to send
1803 the same command reply payload it received back to the
1804 original sender of the command. This way all arguments
1805 that was received by the server will be received by the
1806 client too. Affected file silcd/command.c.
1808 * Added the silc_idcache_add to return the created cache entry
1809 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1811 * Add global clients to expire if they are not on any channel.
1812 This is because normal server will never know if they signoff
1813 if they are not on any channel. The cache expiry will take
1814 case of these entries. This is done by normal servers only.
1815 The affected files are silcd/command_reply.c,
1816 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1818 * If server receives invalid ID notification for WHOIS or
1819 IDENTIFY and the ID exists in the lists, it is removed.
1820 Affected file silcd/command_reply.c.
1822 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1823 in client then client entry that it matches is searched and
1824 the nickname is printed on the screen for user. Affected
1825 file irssi/src/silc/core/client_ops.c.
1827 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1829 * Use cache entry expire time in the LIST command reply to
1830 purge old entries from the cache after the LIST command
1831 reply has been received. This way we don't have non-existent
1832 entries in the cache for too long. Affected file is
1833 silcd/command_reply.c.
1835 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1837 * If we are normal server, and we've not resolved client info
1838 in WHOIS or IDENTIFY from router, and it is global client,
1839 we'll check whether it is on some channel. If it is not
1840 then we cannot be sure about its validity and will resolve it
1841 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1842 file silcd/command.c.
1844 * Search channel by name (if possible) rather than by ID
1845 in IDENTIFY command's command reply. Affected file is
1846 silcd/command_reply.c.
1848 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1850 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1851 Updated specs and implemented it. Affected file silcd/command.c,
1852 silcd/packet_send.c and silcd/packet_receive.c.
1854 * Implemented the <founder auth> payload handling in the JOIN
1855 command. If provided all conditions for channel joining
1856 except requirement to provide correct passphrase can be
1857 overrided by the channel founder. Updated the protocol specs.
1858 Affected file silcd/command.c.
1860 Added support for founder auth in JOIN command in client
1861 library. Fixed the parsing of the JOIN command now to support
1862 all options as they should be. The affected file is
1863 lib/silcclient/command.c.
1865 * Optimized the WHOIS and IDENTIFY commands to send the request
1866 to router only if it includes nicknames or other names. If
1867 they include only IDs then check the local cache first before
1868 routing. Affected file is silcd/command.c.
1870 * Added channels topic announcements. Affected file is
1871 silcd/packet_receive.c and silcd/server.c.
1873 * Fixed the silc_server_send_notify_topic_set to really destine
1874 the packet to channel. Affected file silcd/packet_send.c.
1876 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1877 library. Affected file lib/silcclient/client_notify.c.
1879 * Added UMODE announcements. Affected file silcd/server.c.
1881 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1883 * Memory leak fixes in:
1885 lib/silcutil/silcsockconn.c
1886 lib/silcske/silcske.c
1887 lib/silcske/groups.c
1889 lib/silccrypt/silcpkcs.c
1890 lib/silccore/silccommand.c
1891 lib/silccore/silcidcache.c
1896 * ROBOdoc documented the lib/silcske/groups.h file and a
1897 bit changed the interface for better.
1899 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1901 * Update the client entry context in the ID cache after
1902 nick change. Affected file lib/silcclient/command.c.
1903 Fixes the CUMODE command when regaining founder privileges,
1904 and a little WHOIS problem.
1906 * Fixed silc_net_gethostbyname to correctly call the
1907 inet_ntop. Affected file lib/silcutil/silcnet.c.
1909 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1911 * Added IPv6 support checking to the configure.in.pre, added
1912 also --enable-ipv6 option to override the check. Affected
1913 file configure.in.pre.
1915 * The silc_thread_create now calls the start function
1916 directly if threads support is not compiled in. Removes
1917 ugly #ifdef's from generic code. Affected files are
1918 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1920 * Added silc_net_gethostby[name/addr]_async to asynchronously
1921 resolve. Affected files are lib/silcutil/silcnet.[ch].
1923 * Added support for rendering IPv6 based server, client and
1924 channel IDs. Affected file lib/silcutil/silcutil.c.
1926 * Added support for creating IPv6 based server IDs. Affected
1927 file is silcd/serverid.c.
1929 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1931 * Added silc_net_gethostby[addr/name] into the
1932 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1933 routines. Added silc_net_is_ip[4/6]. Affected file is
1934 lib/silcutil/unix/silcunixnet.c. All routines that take
1935 address as argument now supports both IPv4 and IPv6 addresses.
1937 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1939 * Fixed LIST command reply sending in server. Affected file
1942 * Server now sends the kicker's client ID in the KICK notify
1943 to the kicked client. Affected file silcd/command.c.
1945 * The client library now parses the kickers client ID and
1946 UI displays it. Affected files lib/silcclient/client_notify.c
1947 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1949 * Made all payload parsing function prototypes consistent.
1950 They all take now const unsigned char * and uint32 pair as
1951 the payload data instead of SilcBuffer. Changes all around
1952 the source tree. Other unsigned char* -> const unsigned char*
1953 changes around the tree as well.
1955 * Optimized SFTP client and server packet sending not to
1956 allocate new buffer for each packet but to recycle the
1957 first allocated buffer. Affected files are
1958 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1960 * Optimized the SFTP client to use SilcList instead of
1961 SilcDList for requests, because it is faster. Affected file
1962 is lib/silcsftp/sftp_client.c.
1964 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1965 into lib/silccore/silcid.[ch].
1967 Renamed silcpayload.[ch] into silcargument.[ch].
1969 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1971 * If client entry is deleted with active key agreement
1972 session, abort the session.
1974 The silc_client_abort_key_agreement now calls the completion
1975 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1977 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1980 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1982 * Don't use __restrict in older GCC's. Affected file is
1983 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1985 * silc_net_localhost now attempts to reverse lookup the
1986 IP/hostname. Affected file lib/silcutil/silcnet.c.
1988 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1989 command. It can be used to gain founder privileges at
1990 the same time when joining the channel.
1992 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1993 kicker's client ID as well. Updated protocol specs.
1995 Defined that the server must send SILC_COMMAND_IDENTIFY
1996 command reply with error status to client who sent
1997 private message with invalid client ID.
1999 Updated the protocol specification.
2001 * Added silc_server_send_command_reply to send any
2002 command reply. Affected file silcd/packet_send.[ch].
2004 * Added silc_id_payload_encode_data to encode ID payload
2005 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
2007 * The server now send IDENTIFY command reply with error
2008 status if client ID in private message is invalid. Affected
2009 file silcd/packet_receive.c.
2011 * Save the server key file with server's IP address in
2012 the filename instead of hostname. The affected file is
2013 irssi/src/silc/core/client_ops.c.
2015 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2017 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
2020 * Added libtool support for compiling shared objects in
2021 lib/silcsim. Affected file configure.in.pre and
2022 lib/silcsim/Makefile.am. Original patch by cras.
2024 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2026 * Pid file configuration, and server's config file fixes
2027 patch by toma. Updated CREDITS file.
2029 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2031 * Fixed silc_client_channel_message to not try to decrypt
2032 the message twice if it resolved the destination client
2033 information. This could cause of dropping one channel
2034 message. Affected file lib/silcclient/client_channel.c.
2036 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2038 * Added silc_client_run_one into lib/silcclient/silcapi.h and
2039 lib/silcclient/client.c. This function is used when the SILC
2040 Client is run under some other scheduler, or event loop or
2041 main loop. On GUI applications, for example this may be
2042 desired to used to run the client under the GUI application's
2043 main loop. Typically the GUI application would register an
2044 idle task that calls this function multiple times in a second
2045 to quickly process the SILC specific data.
2047 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2049 * Fixed silc_server_drop() for dropping the supplementary
2050 groups as well, this could cause a security hole on some
2053 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2055 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
2058 * Write PID file after dropping privileges. Added -F option
2059 to run server on foreground. A patch by debolaz.
2060 Affected files silcd/server.c, silcd/silcd.c.
2062 * Fixed MOTD to return the MOTD file server name. Affected
2063 file silcd/command.c.
2065 * Added INFO command reply handling to the Irssi SILC Client.
2066 Affected file irssi/src/silc/core/client_ops.c.
2068 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2070 * Fixed the silc_idcache_list_* routines to really support
2071 the dynamic list. Fixes a crash. Affected file is
2072 lib/silccore/silcidcache.c.
2074 * Fixed the LIST command reply to really call LIST command's
2075 pending callbacks. Affected file silcd/command_reply.c.
2077 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2079 * Update conn->local_entry->nickname after giving NICK
2080 command. Affected file lib/silcclient/command.c.
2082 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2084 * Added the [pid] option to the silcd configuration file
2086 Affected files: serverconfig.[ch] and silcd.c
2088 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2090 * Save fingerprint in WHOIS command reply in server.
2091 Affected file silcd/command_reply.c.
2093 * Fixed NICK commands pending callback registration.
2094 Affected file lib/silcclient/command.c.
2096 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2098 * Use ++server->cmd_ident when sending commands in server,
2099 instead of random number. Affected file silcd/command.c.
2101 * Fixed GETKEY command reply to call actually GETKEY pending
2102 command callbacks. Affected file silcd/command_reply.c.
2104 * A bit stricter check for nicknames. Check for same nickname
2105 in NICK command also. Affected file silcd/command.c.
2107 * Do not call INFO command everytime client ID changes, only
2108 during first connecting. Affected file lib/silcclient/client.c.
2110 * Set the new nickname only after successful command reply for
2111 NICK command is returned by server. Affected file
2112 lib/silcclient/command.c.
2114 * Remove nicknames from nicklist during server_signoff notify.
2115 Should fix /NAMES bit more. The affected file is
2116 irssi/src/silc/core/silc-channels.c.
2118 * Added `fingerprint' field to the SilcIDListData in the
2119 silcd/idlist.h to hold the fingerprint of the client's
2122 Send the fingerprint of the client's public key in WHOIS
2125 Affected files silcd/command.c, and silcd/idlist.[ch].
2127 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2128 create fingerprint from given data.
2130 * Show the fingerprint of the client's public key in WHOIS.
2131 Affected files irssi/src/module-formats.[ch] and
2132 irssi/src/silc/core/client_ops.c.
2134 * Format the multiple same nicknames also during JOIN and
2135 NICK_CHANGE notifys. Affected file is
2136 lib/silcclient/client_notify.c.
2138 * Do not print error on screen for invalid private message
2139 payload since it can come if someone is sending private
2140 messages with wrong key. Affected file
2141 lib/silccore/silcprivate.c.
2143 * Fixed multiple concurrent /PING crash. Affected file
2144 lib/silcclient/command.c.
2146 * Changed the wrong ID encoding. All IP addresses must be
2147 in MSB first order in encoded format. They were encoded
2148 wrong and was in LSB format. Affected files are
2149 silcd/serverid.c, lib/silcutil/silcutil.c.
2151 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2153 * Call the `connect' client operation through the scheduler
2154 in case of error. Affected file lib/silcclient/client.c.
2156 * Call the `failure' client operation even if the error
2157 occurred locally during a protocol. Affected file is
2158 lib/silcclient/protocol.c.
2160 * Added support of sending LIST command to router from normal
2161 server. This way normal server can get list of all channels
2162 in the network too. Fixed the channel list sending in the
2163 server too. Affected files are silcd/command.c, and
2164 silcd/command_reply.[ch].
2166 * Added silc_server_update_channels_by_server and
2167 silc_server_remove_channels_by_server. They are used during
2168 disconnection of primary router and in backup router protocol.
2169 Affected file silcd/server_util.[ch], silcd/server.c and
2170 silcd/server_backup.c.
2172 * Fixed channel adding to global list in IDENTIFY command
2173 reply in server. Affected file silcd/command_reply.c.
2175 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2177 * If the incoming packet type is REKEY or REKEY_DONE process
2178 that packet always synchronously. Fixes yet another MAC
2179 failed error on slow (dialup) connections. Affected file
2180 lib/silcclient/client.c and silcd/server.c.
2182 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Call check_version SKE callback for initiator too. Affected
2185 file lib/silcske/silcske.c.
2187 * Implemented fix for security hole found in the SKE that was
2188 fixed in the specification few days back; the initiator's
2189 public key is now added to the HASH value computation.
2190 Added backwards support for the old way of doing it too, for
2191 old clients and old servers. Affected file is
2192 lib/silcske/silcske.c.
2194 * Enabled mutual authentication by default in SKE. If initiator
2195 is not providing mutual authentication the responder will
2196 force it. This will provide the proof of posession of the
2197 private key for responder. The affected files are
2198 lib/silcclient/protocol.c and silcd/protocol.c.
2200 * Do not cache anymore the server's public key during SKE.
2201 We do mutual authentication so the proof of posession of
2202 private key is done, and if the server is authenticated in
2203 conn auth protocol with public key we must have the public
2204 key already. Affected file silcd/protocol.c.
2206 * Added new global debug variable: silc_debug_hexdump. If
2207 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2208 file lib/silcutil/silclog.[ch].
2210 * Fixed compilation warning due to char * -> const char *.
2211 Affected files lib/silcutil/silcnet.h, and
2212 lib/silccore/silcauth.[ch].
2214 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2216 * Fixed CMODE command when new channel key was created. If
2217 the creation failed the old key was removed. Next time giving
2218 same command would crash the server since the old key was
2219 freed already. Affected file silcd/command.c.
2221 * Fixed the silc_server_announce_get_channels to not crash
2222 on reconnect. Affected file silcd/server.c.
2224 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2226 * Added silc_log_set_debug_string function to set a regex
2227 string to match for debug output. Only the function names,
2228 or filenames matching the given debug string is actually
2229 printed. This way it is possible to filter out those debug
2230 strings that user is not interested in.
2232 Fixed a bug in silc_string_regexify.
2234 Affected files lib/silcutil/silclog.[ch], and
2235 lib/silcutil/unix/silcunixutil.c.
2237 * Changed the -d options in both server and Irssi SILC client
2238 to take the debug string as argument. Affected files
2239 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2241 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2243 * Added silc_hash_babbleprint to create a Bubble Babble
2244 Encoded fingerprint. The encoding is developed by Antti
2245 Huima (draft-huima-babble-01.txt), and it creates human
2246 readable strings out of binary data. Affected file
2247 lib/silccrypt/silchash.[ch].
2249 * Print the babble print now in addition of fingerprint as well
2250 in Irssi SILC client. Affected files are
2251 irssi/src/fe-common/silc/module-formats.[ch],
2252 irssi/src/fe-common/silc/core/client_ops.c.
2254 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2256 * Fixed a security problem found in SKE. The initiator's
2257 public key too is now added to the HASH hash value creation
2258 which is signed by the responder to create the SIGN value.
2259 This will prevent anyone in the middle to lie to the responder
2260 about the initiator's public key. If this is done now, the
2261 man in the middle will get caught. Updated the protocol
2264 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2266 * Better installation directory handling. Configure module
2267 paths and other paths automatically to example_silc* files
2268 in doc/. A patch by toma.
2270 * Fixed compiler warning from MPI library, and from SILC RNG.
2273 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2274 It can be configured with ./configure. A patch by toma.
2276 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2278 * Find correct make to use in prepare-clean. A patch by
2279 toma. Affected file prepare-clean.
2281 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2283 * Added irssi variables use_auto_addr, auto_bind_ip,
2284 auto_bind_port and auto_public_ip.
2286 * Changed the interface for silc_client_send_key_agreement
2287 in lib/silcclient/silcapi.h
2291 irssi/src/silc/core/silc-core.c
2293 lib/silcclient/silcapi.h
2294 irssi/src/silc/core/silc-channels.c
2295 lib/silcclient/client_keyagr.c
2298 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2300 * Added silc_pkcs_public_key_compare to compare two
2301 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2303 * Check that the client who set the founder mode on the
2304 channel is the same client that is giving the founder
2305 mode to itself. It is done by comparing the saved public
2306 key (it is saved even in the authentication is passphrase).
2307 Affected file silcd/command.c.
2309 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2311 * Do not process packet for disconnected socket connection.
2312 Affected file lib/silccore/silcpacket.c.
2314 * Process the DISCONNECT packet through scheduler in the
2315 client library. Affected file lib/silcclient/client.c.
2317 * Fixed the silc_client_packet_parse to not to increase
2318 the packet sequence number if the conn->sock and the
2319 current socket connection is not same. This can happen
2320 for example during key agreement when the conn includes
2321 multiple socket connections (listeners). Affected file
2322 lib/silcclient/client.c.
2324 * The sender of the file transfer request now provides also
2325 the pointer (listener) for the key exchange protocol. If
2326 the listener cannot be created then it sends empty key
2327 agreement and lets the receiver provide the listener.
2329 Added `local_ip' and `local_port' arguments to the
2330 silc_client_file_send. If they are provided they are used,
2331 if not then it will attempt to find local IP address, if
2332 not found or bind fails then the remote client will provide
2335 Affected files are lib/silcclient/client_ftp.c and
2336 lib/silcclient/silcapi.h.
2338 * Extended the FILE SEND command to support defining the
2339 local IP and port for key exchange listener. They are
2340 optional. Affected file irssi/src/silc/core/silc-servers.c.
2342 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Defined to WHOIS command reply the sending of fingerprint
2345 of the client's public key (if the proof of posession of the
2346 corresponding private key is verified by the server).
2347 Updated to the protocol specification.
2349 * Added support of receiving the client's public key's
2350 fingerprint in command reply in client library. Affected
2351 file is lib/silcclient/command_reply.c, and
2352 lib/silcclient/idlist.[ch].
2354 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2356 * Do not send over 128 chars long nickname to the server
2357 in NICK command. Affected file lib/silcclient/command.c.
2359 * Do not send over 256 chars long channel names to the server
2360 in JOIN command. Affected file lib/silcclient/command.c.
2362 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2364 * Assure that silc_server_close_connection cannot be called
2365 twice for same socket context. Affected file is
2368 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2370 * Send error message to application if opening file for
2371 writing during file transfer fails. Affected file is
2372 lib/silcclient/client_ftp.c.
2374 Remove all file transfer sessions for a client that we're
2375 removing from ID cache.
2377 Affected file is lib/silcclient/client_ftp.c.
2379 * Fixed silc_net_addr2bin to return correct address. Affected
2380 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2382 * Fixed file transfer session removing on signoff notify.
2383 Affected file irssi/src/silc/core/silc-servers.c.
2385 * Added the SilcClientFileError to be returned in the monitor
2386 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2387 Affected file lib/silcclient/silcapi.h.
2389 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2391 * Fixed a crash in silc_client_ftp_free_sessions and
2392 silc_client_ftp_session_free_client. Affected file
2393 lib/silcclient/client_ftp.c.
2395 * Added `disabled' field in the SilcChannelEntry in the server
2396 to indicate if the server entry is disabled. Affected file
2397 silcd/idlist.h, silcd/command[_reply].c.
2399 * SILC server adds now /var/run/silcd.pid everytime it is
2400 started. Affected file silcd/silcd.c.
2402 * Added silc_server_packet_send_clients to send a packet to
2403 the provided table of client entries. Affected file
2404 silcd/packet_send.[ch].
2406 * Fixed a crash in client resolving in client_prvmsg.c in
2407 client library. Affected file lib/silcclient/client_prvmsg.c.
2409 * Do not actually remove the client directly from ID cache
2410 during SERVER_SIGNOFF, but invalidate it. This way we
2411 preserve the WHOWAS info for the client. Affected file
2412 silcd/server_util.c.
2414 * Fixed SERVER_SIGNOFF notify handling in the server. The
2415 server is now able to process incoming SERVER_SIGNOFF notify
2416 for a server that it doesn't even know about. It will remove
2417 the clients provided in the notify. Affected file
2418 silcd/packet_receive.c.
2420 * Check for partial packet in data queue after every packet that
2421 was found from the queue. Return and wait for more data if
2422 there is partial data in queue. Affected file is
2423 lib/silccore/silcpacket.c.
2425 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2427 * Added SilcClietFileError enum to indicate error in
2428 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2429 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2430 Affected files lib/silcclient/silcapi.h and
2431 lib/silcclient/client_ftp.c.
2433 * Check that newsize in silc_buffer_realloc is larger than
2434 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2436 * Added better monitor of file transfers. It now monitors
2437 key agreement protocol during the file transfer too. Added
2438 error reporting too. Affected files
2439 irssi/src/silc/core/silc-servers.c,
2440 irssi/src/fe-common/silc/module-formats.[ch].
2442 * Wrote a help file for FILE command.
2444 * Added silc_rng_global_get_byte_fast to get not-so-secure
2445 random data as fast as possible. Random data is read from
2446 /dev/urandom if available and from the SILC RNG if not
2447 available. It is used in padding generation. Affected file
2448 lib/silccrypt/silcrng.[ch].
2450 * All packets in client library are now processed synchronously.
2451 Optimized packet processing a lot. Affected file
2452 lib/silcclient/client.c.
2454 * All server connection packets are processing synchronously
2455 now in server, to optimize packet processing. Affected file
2458 * Include files are installed now only in Toolkit distribution
2459 if make install is given. Affected files: all Makefile.am's.
2461 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2463 * Assure that silc_client_notify_by_server_resolve does not
2464 resolve the client information multiple times. If it cannot
2465 be found by the first it cannot be found at all. Affected
2466 file lib/silcclient/client_notify.c.
2468 * Fixed WHOWAS command reply calling. Affected file
2469 lib/silcclient/command_reply.c.
2471 * Removed all references to silc_idlist_get_client from the
2472 Irssi SILC client since that call is internal call used by
2473 the library. The Irssi SILC client will use now client
2474 retrieval functions found in silcapi.h.
2476 * Fixed a bug in resolving nickname info before sending
2477 private message. It used freed memory. Affected file
2478 irssi/src/silc/core/silc-servers.c.
2480 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2482 * Assure my_channels statistics cannot go negative in server.
2483 Affected files silcd/server.c, silcd/server_util.c.
2485 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2487 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2489 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2491 * Win32 Toolkit changes. Affected files
2492 win32/silc.dsw, win32/libsilc/libsilc.def,
2493 win32/libsilcclient/libsilc.def,
2494 lib/silcutil/silcutil.c, and
2495 lib/sftp/sftp_fs_memory.c.
2497 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2499 * Added silc_net_localip to return local host's IP address.
2500 Affected file lib/silcutil/silcnet.[ch].
2502 * If key exchange or rekey protocol is active for a connection
2503 parse all packets syncronously since there might be packets
2504 in packet queue that we are not able to process without first
2505 processing packets before them. Affected file silcd/server,
2506 lib/silcclient/client.c.
2508 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2509 whether library should continue processing the packet.
2510 Affected file lib/silccore/silcpacket.h.
2512 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2513 SilcSFTPMonitorData to SFTP server to monitor various
2514 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2515 lib/silcsftp/sftp_server.c.
2517 * Added silc_file_size to return file size. Affected file

2522 transmission. Affected file lib/silcclient/client_ftp.c,
2523 lib/silccilent/client.[ch].
2525 * Added new local command FILE to the Irssi SILC Client.
2526 It is used to perform the file transfer. It has subcommands
2527 SEND, RECEIVE, SHOW and CLOSE. Affected files
2528 irssi/src/silc/core/client_ops.c,
2529 irssi/src/silc/core/silc-server.[ch].
2531 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2533 * Relay the SILC_PACKET_FTP in the server. Affected files
2534 silcd/server.c and silcd/packet_receive.c.
2536 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2538 * Renamed silc_file_read and silc_file_write to functions
2539 silc_file_readfile and silc_file_writefile. Added function
2540 silc_file_open and silc_file_close. Affected files
2541 lib/silcutil/silcutil.[ch].
2543 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2545 * Resolve the client info when received private message or
2546 channel message for a client which nickname we don't know.
2547 Affected files lib/silcclient/client_prvmsg.c and
2548 lib/silcclient/client_channel.c.
2550 * Do not crash in /KEY if client is not connected. Affected
2551 file irssi/src/silc/core/silc-channels.c.
2553 * Added SilcClientStatus field to the SilcClientEntry in the
2554 lib/silcclient/idlist.h.
2556 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2557 is incomplete and is being resolved, it won't be resolved
2560 Make sure also that USERS command reply does not resolve
2561 twice information. Affected file is
2562 lib/silcclient/command_reply.c.
2564 Make sure that silc_client_get_clients_by_list does not
2565 resolve twice same information.
2567 * Check for valid client->id in the silc_server_free_client_data.
2568 Affected file silcd/server.c.
2570 * Fixed /GETKEY nick@server not to crash if the server entry
2571 is not found. Affected file lib/silcclient/command.c.
2573 * Fixed the silc_server_check_cmode_rights to check the
2574 requested modes correctly. Affected file silcd/command.c.
2576 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2578 * Better checks for non-printable chars in nick added.
2579 Affected file silcd/command.c.
2581 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2583 * Call the silc_server_udpate_servers_by_server in the
2584 primary router that comes back online in the backup resuming
2585 protocol. Otherwise it routes packets wrong. Affected file
2586 silcd/server_util.[ch], silcd/server_backup.c.
2588 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2590 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2591 lib/silcutil/silcbuffmt.[ch].
2593 * Redefined the SILC packet header to include the padding
2594 length. Affected file lib/silccore/silcpacket.[ch].
2596 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2597 length for maximum padding up to 128 bytes). Affected
2598 file lib/silccore/silcpacket.h.
2600 * Removed all backwards support for old 0.5.x MAC thingies.
2601 The SILC packet header change makes it impossible to be
2602 backwards compatible.
2604 * Send the ENDING packet with timeout in the backup resuming
2605 protocol. This is to assure that all routers has connected
2606 to the primary router. Affected file silcd/server_backup.c.
2608 * Changed the RNG to take the first IV from random data. It
2609 used to take it from zero actually. Changed the RNG also
2610 to use /dev/urandom during session. /dev/random is used
2611 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2613 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2615 * Changed the SILC packet header to have the first two bytes
2616 (the packet length) encrypted. Affected files aroung the
2617 code tree, lib/silccore/silcpacket.[ch]. Removed the
2618 SilcPacketCheckDecrypt callback. It is not needed anymore
2619 since the silc_packet_receive_process will determine now
2620 whether the packet is normal or special.
2622 * Implemented the unidirectional MAC keys. Affected files
2623 lib/silcske/silcske.c, silcd/protocol.c and
2624 lib/silcclient/protocol.c.
2626 * Implemented the packet sequence number to the MAC computation.
2627 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2628 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2629 lib/silcclient/protocol.c.
2631 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2633 * Allow backup router to announce servers. All servers
2634 announced by backup router are added to the global list
2635 automatically. Update hte server's socket to our primary
2636 router also when backup router announces a server.
2637 Affected file silcd/packet_receive.c.
2639 * Do not update the client->router in the function
2640 silc_server_udpate_clients_by_server if the client is on
2641 global list. We might fail to find any specific server
2642 for locally connected clients and local cell clients. They
2643 should still use the `from' and not `to' as client->router.
2644 This fixes backup router resuming protocol. Affected file
2645 silcd/server_util.c.
2647 * Decrease channel statistics count only if the channel
2648 deletion worked. Affected files are silcd/server.c and
2649 silcd/server_util.c.
2651 * Added silc_server_update_servers_by_server to update origin
2652 of all server entries. Used during backup router protocol.
2653 Affected files silcd/server_util.[ch], silcd/server.c. and
2654 silcd/backup_router.c.
2656 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2657 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2658 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2659 lib/silccrypt/silchmac.c.
2661 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2663 * Assure that router cannot reroute the same channel message
2664 to the sender. Affected file silcd/packet_receive.c.
2666 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2668 * Made better checks that the channel message is not sent
2669 to the router it came from. Affected file is
2670 silcd/packet_send.c. Fixed memory leak too.
2672 * Announce informations for incoming router connection, but
2673 only after checking if it is replaced by backup router.
2674 Affected file silcd/packet_receive.c.
2676 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * Fixed the backup resuming protocol to work in multiple
2679 router environment. Affected file silcd/server_backup.c.
2681 * Route packet only to one router in the function
2682 silc_server_packet_send_to_channel. Affected file is
2683 silcd/packet_send.c.
2685 * Fixed silc_server_send_notify_dest to set the broadcast
2686 flag. Fixed the silc_server_send_notify_topic to actually
2687 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2688 Affected file silcd/packet_send.c.
2690 * Changed the SFTP Filesystem interface. Changed the
2691 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2692 the filesystem operation function. The SilcSFTPFilesystem
2693 is now a context that is allocated by all filesystem allocation
2694 functions and it already includes the operations structure
2695 and filesystem specific context. It is given as argument
2696 now to the silc_sftp_server_start. This made the interface
2697 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2698 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2700 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2702 * Changed the backup router adding and getting interfaces
2703 in the server. The router that will be replaced by the
2704 specified backup router is now sent as argument. Affected
2705 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2708 * Added silc_net_addr2bin_ne to return the binary form of
2709 the IP address in network byte order. Affected files
2710 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2712 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2714 * Check for existing server ID in silc_server_new_server
2715 and in silc_server_connect_to_router_final and remove the
2716 old entry if it exists. Affected file silcd/packet_receive.c,
2719 * Send the channel message always to only one router, either
2720 in upstream or downstream. Affected file is
2721 silcd/packet_send.c.
2723 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2725 * Wrote the definition of the backup resuming protocol to the
2726 protocol specification.
2728 * Removed one redundant channel key generation from normal
2729 server during joining procedure. Removed one redundant
2730 channel key sending from server to router during joining
2731 procedure. Affected file silcd/command.c.
2733 * Made minor bugfixes to the backup router resuming protocol.
2734 Affected file silcd/server_backup.c, server.c.
2736 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2738 * Added --disable-asm configuration option. Affected files
2739 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2742 * Implemented the backup resuming protocol that is used to
2743 resume the primary router position in the cell after the
2744 primary router comes back online. Affected files
2745 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2746 and silcd/server_util.[ch].
2748 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2750 * Sleep two (2) seconds after sending QUIT command to server.
2751 Affected file lib/silcclient/command.c.
2753 * Assure that if outgoing data buffer is pending do not force
2754 send any data. Affected file silcd/packet_send.c.
2756 * Assure that if outgoing data buffer is pending do not force
2757 send any data. Affected file lib/silcclient/client.c.
2759 * Implemented the backup router support when the primary router
2760 goes down. The servers and routers can now use the backup
2761 router as new primary router without loosing connectivity.
2763 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2765 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2766 in the server to indicate disabled entry. All data read
2767 from the connection will be ignored and no data is sent
2768 for entry that is disabled. Affected files are
2769 silcd/idlist.h, silcd/server.c.
2771 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2773 * Created SFTP client and server test programs in the
2774 lib/silcsftp/tests directory.
2776 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2778 * Implemented memory filesystem (virtual filesystem) for
2779 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2782 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2784 * Implemented the SFTP (SSH File Transfer Protocol) to the
2785 lib/silcsftp. It includes SFTP client and SFTP server
2788 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2790 * Moved lib/silccore/silcprotocol.[ch] to the
2791 lib/silcutil library.
2793 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2794 take variable argument list pointer as argument. Affected
2795 file lib/silcutil/silcbuffmt.[ch].
2797 * Added silc_buffer_set function that is used to set data
2798 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2799 Affected file lib/silcutil/silcbuffer.h.
2801 * Changed various routines in the core library to use the new
2802 silc_buffer_set instead of allocating new buffer only for
2805 * Added 64-bit value formatting and unformatting support to the
2806 silc_buffer_[un]format routines. Affected file is
2807 lib/silcutil/silcbuffmt.[ch].
2809 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2810 to includes/bitmove.h.
2812 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2814 * Fixed channel user mode saving in client library. Affected
2815 file lib/silcclient/command[_reply].c.
2817 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2819 * Defined the file transfer to the SILC Protocol. Added
2820 new packet type SILC_PACKET_FTP and defined File Transfer
2821 Payload. The mandatory file transfer protocol is SFTP
2822 (SSH File Transfer Protocol). Affected file in addition
2823 of the internet draft is lib/silccore/silcpacket.h.
2825 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2826 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2827 is used as part of backup router protocol when the primary
2828 router of the cell is back online and wishes to resume
2829 the position as primary router.
2831 * Redefined the MAC generation keys in the protocol. The
2832 same key is not used anymore in both direction. Both
2833 direction will now use different keys for sending and
2834 receiving. This fixes a potential security flaw. This
2835 change causes incompatibilities in the protocol.
2837 * Redefined also the MAC computation from the packet.
2838 An packet sequence number is now added to the MAC
2839 computation. This prevents possible replay attacks against
2840 the protocol. This change too causes incompatibilities
2843 Added `sequence' field to the SilcPacketContext to hold
2844 the current sequence number for the packet.
2846 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2848 * Added `created' field to the SilcIDListData in the file
2849 silcd/idlist.h to indicate the time when the entry was
2852 * Added `created' field to the SilcChannelEntry too. Affected
2853 file silcd/idlist.h.
2855 * Added `creation_time' aguments to all the announcement functions
2856 in the server. If it is provided then only the entries that
2857 was created after the provided time frame are actually
2858 announced. Affected file silcd/server.[ch].
2860 * The protocol says that the Channel ID's IP address must be
2861 based on the router's IP address. Added check for this in
2862 the silc_server_new_channel when processing incoming New Channel
2863 Payload. Affected file silcd/packet_receive.c.
2865 * Print out the correct version with --version in SILC client.
2866 Affected file irssi/src/silc/core/silc-core.c.
2868 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Fixed WHOWAS command to check for completnes of the client
2871 entry always, not just when the command is coming from client.
2872 Affected file silcd/command.c.
2874 * Added new function silc_server_packet_queue_purge to purge the
2875 outgoing data queue to the network. After the function returns
2876 it is guaranteed that the outgoing packet queue is empty.
2877 Affected file silcd/packet_send.[ch].
2879 * Purge the outgoing packet queue in the rekey protocol's final
2880 callback to assure that all rekey packets go to the network
2881 before quitting the protocol. Affected file silcd/server.c.
2883 * Added silc_client_packet_queue_parse as similar function as
2884 in server to the client library. The affected file is
2885 lib/silcclient/client.c.
2887 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2889 * Splitted silcd/server.c and created silcd/server_util.[ch]
2890 for utility functions.
2892 * Added new socket flag SILC_SF_DISABLED to indicate that the
2893 connection is open but nothing can be sent to or received from
2894 the connection. Affected file lib/silcutil/silsockconn.[ch].
2895 The checking for disabled socket is checked in the low level
2896 silc_socket_write and silc_socket_read functions.
2898 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2900 * Allow only nicknames and channel names that fits into the
2901 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2903 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2905 * When processing JOIN command reply in server check that if
2906 the channel exists in our global list we'll move it the local
2907 list. Affected file silcd/command_reply.c.
2909 * Fixed the check whether client is joined on the channel already
2910 in JOIN command. Affected file lib/silcclient/command.c.
2912 * Fixed the JOIN command reply to check whether the channel
2913 already exists. Affected file lib/silcclient/command_reply.c.
2915 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2917 * Added silc_ske_status_string to map the SKE error numbers
2918 to readable strings. The affected files are
2919 lib/silcske/silcske[_status].[ch].
2921 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * Do not show the private channels on the WHOIS channel list
2924 as it is not allowed by the protocol. The affected file is
2927 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2929 * Assure that the packet length digged from the actual packet
2930 is something sensible in the silc_packet_decrypt_rest_special
2931 in lib/silccrypt/silcpacket.c.
2933 * Free and NULL the allocated pointer in silc_hmac_alloc if
2934 the HMAC allocation fails. The affected file is
2935 lib/silccrypt/silchmac.c.
2937 * Print the selected security properties to the log files in
2938 the server. Affected file silcd/protocol.c.
2940 * Add SKE's reference counter even if calling the completion
2941 callback manually. Otherwise it goes negative, although it
2942 does not cause any problems. The affected file is
2943 lib/silcske/silcske.c.
2945 * Remove the client entry with short timeout after giving the
2946 KILL command. Affected file lib/silcclient/command.c.
2948 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2949 case all found clients are already disconnected (WHOWAS would
2950 found them) in the server. Affected file silcd/command.c.
2952 * Update the last_receive (time of last data received) to be
2953 updated only when received private or channel message so that
2954 the idle time showed in WHOIS makes more sense.
2956 * Added boolean field `valid' in to the SilcClientEntry in the
2957 client library to indicate whether the entry is valid or not.
2958 This fixes the nickname change bug on channel when changing
2959 the nickname to be same than the old (like nick to Nick) the
2960 nickname formatter doesn't set the new nick anymore to Nick@host.
2961 Affected file lib/silcclient/idlist.[ch].
2963 * Now actually fixed the nickname changing on disconnection.
2964 Added new function silc_change_nick to the Irssi SILC Client.
2965 Affected file irssi/src/silc/core/client_ops.c,
2966 irssi/src/silc/core/silc-nicklist.[ch].
2968 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2970 * Check that the public key exists in the GETKEY command before
2971 trying to encode it. Affected file silcd/command.c.
2973 * Print some notifications on received public keys with GETKEY
2974 command in the Irssi SILC Client. Affected files are
2975 irssi/src/fe-common/silc/module-formats.[ch],
2976 irssi/src/silc/core/client_ops.c.
2978 * Use IDENTIFY command to resolve the server information in the
2979 GETKEY command instead of INFO command. Affected file
2980 lib/silcclient/command.c.
2982 * All command reply functions in the client library now calls
2983 the pending command reply callbacks even if an error has
2984 occurred. The server has done this a long time and now it was
2985 time to move the client library to this as well. Now all
2986 errors can be delivered back to the pending command reply
2987 callbacks if necessary. Affected files are
2988 lib/silcclient/command[_reply].[ch].
2990 * Change the nickname on disconnection back to the username
2991 because in reconnect the server will enforce it to it anyway.
2992 Affected file irssi/src/silc/core/silc-servers.c.
2994 * Fixed a config file parsing bug in the Irssi SILC client.
2995 Affected file irssi/src/silc/core/clientconfig.c.
2997 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2999 * When printing the channel mode on JOIN, verify that the
3000 channel key and channel's HMAC are valid. Affected file
3001 irssi/src/silc/core/client_ops.c.
3003 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3005 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
3006 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
3007 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
3009 * Removed channel key rekey task deleting from the function
3010 silc_server_save_channel_key. Affected file silcd/server.c.
3011 Added explicit timeout task context instead that is used to
3012 delete the task if we are registering a new task before the
3013 new task has elapsed.
3015 * When channel key rekey occurs the client library now saves
3016 the old channel key for a short period of time (10 seconds) and
3017 is able to use it in case some is still sending channel
3018 messages encrypted with the old key after the rekey. Affected
3019 file lib/silcclient/[idlist.h|client_channel.c].
3021 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3023 * Added check to the silc_server_new_id_real to not accept
3024 new ID if it is the sender's own ID. Affected file is
3025 silcd/packet_receive.c.
3027 * Assure that we do not announce ourself or the one we've
3028 sending our announcements when we're router and are announcing
3029 servers to our primary router. Affected file silcd/server.c.
3031 * Fixed silc_server_command_identify_check_client to assemble
3032 correct WHOIS packet. It send corrupted WHOIS packet and
3033 caused problem with router to router connections. Affected
3034 file silcd/command.c.
3036 Fixed also silc_server_command_whois_check the same way
3037 as for the IDENTIFY command.
3039 * Added new SilcIDListStatus to the server in the SilcIDListData
3040 structure. The status now includes the current status of
3041 the entry (like registered, resolved etc.). Affected file
3042 silcd/idlist.[ch]. Defined a bunch of different status types
3043 as well. This replaced the old boolean registered field as well.
3045 Added resolve_cmd_ident field to the SilcClientEntry structure
3046 too so that if the entry is for example being resolved so
3047 another command may attach to the same pending command reply
3048 without requiring to resolve the same entry again. This concept
3049 should optimize the WHOIS and the IDENTIFY resolving under
3050 heavy load by taking away unnecessary resolving for entries
3051 that are being resolved already.
3053 Added support for adding multiple pending commands for one
3054 command idenfier. Affected file silcd/command[_reply].[ch].
3056 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3057 before deleting the data. Otherwise the hash table will have
3058 freed data in comparison functions. Affected file is
3059 silcd/command_reply.c.
3061 * Fixed silc_idlist_replace_client_id to add the new entry to
3062 the cache with NULL nickname. Otherwise there will be invalid
3063 memory as the nickname after the nickname is freed. Affected
3064 file silcd/packet_receive.c.
3066 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3067 saved into wrong slots because the previous number of entries
3068 was not taken into account. Affected file silcd/idlist.c.
3069 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3071 * If we are router and we receive JOIN notify to a channel that
3072 does not have any users then notified client is marked as the
3073 channel founder, as it is it. The affected file is
3074 silcd/packet_receive.c
3076 * Added to the extended hash table API's table_del_*ext functions
3077 the destructor as argument too, so that the caller can decide
3078 which destructor to use or whether to use destructor at all.
3079 Affected file lib/silcutil/silchashtable.[ch].
3081 * Fixed ID Cache purging. It actually deleted the entries from
3082 the hash table after the data was freed. The hash table ended
3083 up comparing freed memory. The affected file is
3084 lib/silccore/silcidcache.c.
3086 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3088 * Fixed Irssi SILC client's KILL command's HELP syntax.
3090 * The USERS command now resolves the detailed user information
3091 if the userinfo field is missing. Affected file is
3092 lib/silcclient/command_reply.c.
3094 * Do not print error in silc_file_read if the read file does
3095 not exist. Just silently return NULL. Affected file is
3096 lib/silcutil/silcutil.c.
3098 * Fixed the silc_log_output to not wine about NULL filename
3099 and to not create some bogus " " filename. Affected file is
3100 lib/silcutil/silclog.c.
3102 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3104 * Fixed various printing bugs on the user interface in the
3105 Irssi SILC Client. Minor changes that were forgotten from
3108 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3110 * Fixed the configure.in.pre and the compilation and distribution
3111 environment to support the new autoconf 2.52. That version is
3112 now required to compile the CVS trunk.
3114 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3116 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3117 to generally parse user@fqdn format strings. Affected file
3118 lib/silcutil/silcutil.c.
3120 * Added nickname_format and nickname_force_format fields to the
3121 SilcClientParams structure. The first one defines the format
3122 for the nicknames that the library will enforce if the receives
3123 multiple same nicknames. The second one is boolean value and
3124 can be used to force the library to always enforce the format
3125 to the nicknames regardles whether there are multiple nicknames
3126 or not. This configurable formatting was employed to flexibly
3127 support accessing multiple nicknames from the user interface.
3128 The userinterface can now set the nicknames to what ever format
3129 they prefer. Affected file lib/silcclient/silcapi.h.
3131 Added function silc_client_nickname_format to the file
3132 lib/silcclient/idlist.c. It performs the nickname formatting.
3134 Added new field `hostname´ to the SilcClientEntry context.
3135 It holds the hostname of the client. Affected file is
3136 lib/silcclient/idlist.h.
3138 * Irssi SILC Client sets the nicknames in nick@hostn format.
3139 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3140 irssi/src/silc/core/silc-core.c.
3142 The WHOIS printing now also shows both the real nickname and
3143 the formatted nickname so that user knows how to access the
3144 user if there are multiple same nicknames cached. Affected
3145 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3146 printing formatting too to take the hostname now as a separate
3147 argument. The Affected file is
3148 irssi/src/fe-common/silc/modules-formats.[ch].
3150 * Changed the silc_client_get_clients_local to accept the formatted
3151 nickname as argument. It accepts the real nickname too but the
3152 formatted nickname can be used to find the true entry from
3153 multiple entries. Affected file lib/silcclient/silcapi.h and
3154 lib/silcclient/idlist.c.
3156 * Added nickname_format_parse field to the SilcClientParams.
3157 It is a callback function provided by the application to parse
3158 the nickname out of the formatted nickname string. The library
3159 calls it to get the nickname from the formatted string. Since
3160 the application generally knows better the format of the nickname
3161 string it parses it instead of the library, even though library
3162 encodes the formatted string. If the callback function is not
3163 provided then the library will use the string as is. The
3164 affected file is lib/silcclient/silcapi.h.
3166 * All the nickname strings passed to the client library in
3167 commands are now expected to be formatted nickname strings.
3168 If the command does not support the formatted nickname string
3169 it will assume that the sent string is the actual nickname.
3170 Affected file lib/silcclient/command.c.
3172 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3174 * Added public key authentication support to OPER and SILCOPER
3175 commands in the client library. Affected file is
3176 lib/silcclient/command.c.
3178 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3180 * Changed the get_auth_methdod client operation to be asynchronous.
3181 It can be async if the application resolves the authentication
3182 method from the server during the negotiation. Added new
3183 SilcGetAuthMeth completion callback that the application will
3184 call after resolving the authentication method.
3186 Added function silc_client_request_authentication_method that
3187 the application can use to resolve the authentication method
3188 from the server. Added also SilcConnectionAuthRequest callback
3189 that the library will call after the server has replied. The
3190 application can call this function if it does not know the
3191 current authentication method.
3193 Affected files are lib/silcclient/client.c and
3194 lib/silcclient/silcapi.h.
3196 * The Irssi SILC client now automatically resolves the authentication
3197 method incase any configuration information is not present (and
3198 currently there never is). The affected file is
3199 irssi/src/silc/core/client_ops.c.
3201 * Fixed public key authentication from the client library.
3202 Affected file lib/silcclient/protocol.c. Changed also the
3203 protocol specification about the public key authentication in
3204 the connection authentication protocol. The actual data to be
3205 signed is now computed with a hash function before signing.
3207 * Fixed the public key authentication from the server as well.
3208 Affected file silcd/protocol.c.
3210 * Removed the mlock()'s from the memory allocation routines.
3211 Affected file lib/silcutil/silcmemory.c. The ./configure does
3212 not check anymore for the mlock(). Affected file is
3215 * Fixed USERS command in server to allow the execution of the
3216 command for private and secret channels if the client sending
3217 the command is on the channel. Affected file silcd/command.c.
3219 * Fixed silc_client_get_clients_local to return the clients
3220 count correctly. It could return wrong value. Affected file
3221 lib/silcclient/idlist.c.
3223 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3225 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3226 types. The assembler optimizations seemed not to like 64-bit
3227 data types. The assmebler optimizations thus are now enabled
3228 also for BSD systems as opposed to only enable them for Linux.
3230 * Do not check for threads at all on BSD systems. Affected
3231 file configure.in.pre.
3233 * Removed -n and -h options from the Irssi SILC Client since
3234 they are not used in silc.
3236 * Fixed the prime generation to assure that the first digit
3237 of the generated random number is not zero since our conversion
3238 routines does not like number strings that starts with zero
3239 digit. If zero digit is seen the random number is regenerated.
3240 This caused some corrupted RSA keys when the zero first digit
3241 was met. Affected file lib/silcmath/silcprimegen.c.
3243 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3245 * Fixed WIN32 configuration in the ./configure script.
3246 Fixed to include xti.h on environments that has it.
3247 Patches by Carsten Ilchmann and andrew.
3249 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3251 * Changed the silc_id_create_client_id to be collision
3252 resistant. It is now assured that there cannot be created
3253 two same client ID's. I suspect that some weird bugs in
3254 the server were actually caused by duplicate Client IDs.
3255 Affected file silcd/serverid.[ch]. A router receiving
3256 new ID now also assures and informs the sending server
3257 if the ID caused collision.
3259 * Changed the silc_id_create_channel_id to also assure that
3260 there are no collisions.
3262 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3264 * Statement about ignoring the Mutual Authentication flag when
3265 performing rekey with PFS was a bit misleading. It is ignored
3266 if it was set in the initial negotiation, it cannot be even
3267 set in the rekey. Fixed in the ke-auth draft. Started the
3268 new versions of the protocol drafts in the doc/.
3270 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3272 * Fixed a bug in silc_client_command_identify_save when saving
3273 new channel information. The channel name was no duplicated
3274 and caused crash on exit. Affected file is
3275 lib/silcclient/command_reply.c.
3277 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3279 * Fixed the getkey command handling in the server. Send just
3280 empty OK reply to the sender if the key could not be fetched
3281 (but everything else was ok, like the key just was not available).
3282 Changed the public key parameter to optional in the protocol
3283 specs so that empty OK reply can be sent. Affected file
3286 Added a message to Irssi SILC client to tell to user if the
3287 server did not return a public key.
3289 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3291 * Fixed a channel key regeneration bug. It registered new
3292 timeout tasks exponentially until all system resources were
3293 used. Affected file silcd/server.c.
3295 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3297 * Added the SILC Document generator to the scripts/silcdoc.
3298 It can be used to generate the Toolkit Reference Manual out
3299 of the source tree. Internally it will also use the RoboDoc
3300 generator now imported in util/robodoc.
3302 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3304 * Added couple of return's in rekey protocol if error orccurred
3305 during the protocol. The execution must be terminated.
3306 Affected file silcd/protocol.c. Also, terminate the protocol
3307 always with timeout.
3309 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3311 * The client's Client ID was created initally from the wrong
3312 nickname (it could have been in format nick@host) in the
3313 silc_server_new_client. Affected file silcd/packet_receive.c
3315 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3317 * Added some SILC_LOG_ERROR's to various error conditions
3318 if client could not be added to ID cache. Affected files
3319 silcd/packet_receive.c and silcd/server.c.
3321 * When client's sock->user_data is freed, NULL also the
3322 client->router and client->connection pointers. Added check
3323 for these pointers being NULL to various places around the
3324 code. Affected file silcd/server.c.
3326 * Added client->data.registered == TRUE checks to various
3327 places around the code to assure that unregistered client's
3328 are not handled when it is not allowed. Affected file
3331 * Added `bool registered' fields to all
3332 silc_idlist_[server|client]_get_* routines to indicate whether
3333 the fetched client needs to be registered or not. Affected
3334 file silcd/idlist.[ch].
3336 * Add your own entry as registered to the ID cache in the
3337 server. Affected file server.c.
3339 * Fixed a bug in silc_server_new_server. The SilcServer was
3340 set as the new server's context instead of SilcServerEntry.
3341 This naturally caused some weird bugs.
3343 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3345 * Do not delete the channel rekey task when adding it
3346 for in silc_server_create_channel_key.
3348 * Changed the silc_server_create_channel_key to return
3349 TRUE or FALSE to indicate the success of the channel key
3352 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3354 * Fixed MSVC++ project files and added missing files to
3355 Makefiles under win32/.
3357 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3359 * Do not add TCP_NODELAY flag if the operating system
3360 does not have it defined. Affected files are
3361 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3363 * Fixed buffer overflow from Irssi SILC Client. Affected
3364 file irssi/src/fe-common/core/themes.c.
3366 * Fixed double free in client library in the file
3367 lib/silcclient/client.c when disconnecting from server.
3369 * Applied double free patch from cras to Irssi SILC client.
3370 Affected files irssi/src/core/[modules/expandos].c
3372 * Fixed the disconnection handling to Irssi SILC Client.
3373 The application must call silc_client_close_connection
3374 in ops->connect client operation in case of failure of
3375 the connection. Affected file is
3376 irssi/src/silc/core/client_ops.c.
3378 * Do not set sock->protocol to NULL in the function
3379 silc_client_close_connection after executing the protocol's
3380 final callback since the sock might not be valid anymore.
3381 Affected file lib/silcclient/client.c.
3383 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3385 * Do not enable SILC_THREADS if the linking with libpthread
3386 did not happen. Affected file configure.in.pre.
3388 * Added notion to protocol specification that server must
3389 verify the sent authentication payload with CMODE when
3390 setting the channel founder key. Implemented it to the
3391 server. Affected file silcd/command.c.
3393 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3395 * Added _EXTRA_DIST SILC distribution variable to the
3396 distributions file. It is used to conditionally add extra
3397 files or directories to the specific distribution. Affected
3398 files ./prepare, Makefile.am.pre and distributions.
3400 Removed the `_' from the start of the distribution names.
3403 * Added README.WIN32 for instructions to compile the Toolkit
3406 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3408 * Fixed a double free in disconnection in the server. Affected
3409 file is silcd/server.c.
3411 * Fixed the lib/silcske/groups.c to work now also with GMP
3412 MP library. The string conversion did not work when using
3413 specific base and the base is indicated in the string as well.
3415 * Created win32/ directory which now includes MSVC++ specific
3416 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3417 It will appear only in the toolkit distribution
3419 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3421 * Changed the key material distribution function in case when
3422 the hash output is too short. The data is now concatenated
3423 a bit differently than it used to. Made the change to the
3424 SKE protocol specification.
3426 * Added better GMP detection to configure.in.pre. A patch
3429 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3431 * Fixed a minor bug in SKE that might cause some problem on
3432 some platforms. Affected file lib/silcske/silcske.c.
3434 * Added the cookie checking for initiator in the SKE. It checks
3435 that the responder returns the sent cookie unmodified. The
3436 affected file is lib/silcske/silcske.c. Added new SKE
3437 error type INVALID_COOKIE that can be sent during the
3438 negotiation. Fixed some memory leaks as well.
3440 * Added the "invalid cookie" error message to Irssi SILC client's
3443 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3445 * Added `task_max' field to the SilcClientParams to indicate
3446 the maximum tasks the scheduler can handle. If set to zero,
3447 default values are used. Affected file lib/silcclient/silcapi.h.
3449 * Fixed memory leaks in silc_client_close_connection. Affected
3450 file lib/silcclient/client.c.
3452 * Added silc_client_del_client_entry to client library to free
3453 all memory of given client entry. Affected file is
3454 lib/silcclient/idlist.[ch].
3456 * Added new functions silc_client_del_channel and
3457 silc_client_del_server to delete channel and server entries.
3458 Affected file lib/silcclient/[silcapi.h/idlist.c].
3460 * Removed silc_client_del_client_by_id from silcapi.h.
3462 * Fixed the INFO command to return the server's own info
3463 correctly when querying by Server ID. Affected file is
3466 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3468 * Removed the non-blocking settings in WIN32 code in the
3469 silc_sock_[read/write] and added SleepEx instead. Affected
3470 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3471 of input data is now checked with FIONREAD and ioctlsocket.
3473 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3475 * Call silc_schedule_task_del_by_context in the
3476 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3477 Affected file lib/silccore/silcprotocol.c.
3479 * Call silc_protocol_cancel for active protocols in the
3480 silc_server_close_connection if the funtion
3481 silc_server_free_sock_user_data has not been called.
3482 Affected file silcd/server.c.
3484 * Generic tasks cannot be deleted using the del_by_fd
3485 task deleting function since generic tasks does not match
3486 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3488 * Added a notion to SILCOPER help file that the SILCOPER works
3489 only on router server, not on normal server.
3491 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3493 * Added for WIN32 support for the new scheduler as well.
3494 Affected file lib/silcutil/win32/silcwin32schedule.c.
3496 * Fixed the SHA1 implementation to work on various platforms.
3498 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3500 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3501 API. It is part of the scheduler now. Everything else is
3502 as previously but some functions has changed their names.
3503 Checkout the lib/silcutil/silcschedule.h for the interface.
3504 Updated all applications to use the new interface. Affected
3505 files are lib/silcutil/silcschedule.[ch].
3507 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3509 * Found a bug in the SKE implementation. The HASH value,
3510 specified by the protocol, was not computed correctly. The
3511 public key of the responder was not added to the computation
3512 even though it is mandatory. Affected file lib/silcske/silcske.c.
3513 This unfortunately causes incompatibilities with older
3514 clients and servers.
3516 * Added WIN32 specific network init and uninit functions:
3517 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3518 the Winsock2. Affected file lib/silcutil/silcnet.h and
3519 lib/silcutil/win32/silcwin32net.c.
3521 * Set the socket always to nonblocking mode on WIN32 after
3522 reading data or writing data. Affected file is
3523 lib/silcutil/win32/silcwin32sockconn.c.
3525 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3527 * Fixed various compilation problems under WIN32. Affected
3528 files lib/silcutil/win32/silcwin32thread.c and
3529 lib/silcutil/win32/silcwin32schedule.c.
3531 * Removed all _internal.h #includes from public header
3532 files. Internal headers must never be included from
3535 Removed also the lib/silcske/payload_internal.h file.
3537 * All include files that may be needed (public and some others
3538 included by the public headers) by application developers are
3539 now copied to the ./includes directory. It does not copy any
3540 internal headers. Affected file Makefile.defines.pre and all
3541 Makefile.am's under lib/ and subdirs.
3543 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3545 * Do not change the ~/.silc directory's permissions automatically.
3546 Affected file irssi/src/silc/core/clientutil.c.
3548 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3550 * Do not cancel the protocol in silc_server_close_connection
3551 it might cause recursion. Now cancelled in the function
3552 silc_server_free_sock_user_data. Affected file silcd/server.c.
3554 * Fixed the silc_server_remove_clients_by_server to regenerate
3555 the channel keys correctly finally. Added also new function
3556 silc_server_remove_clients_channels to actually do it.
3557 Affected file silcd/server.c.
3559 * Fixed the silc_server_new_channel to not crash by giving
3560 wrong router to the new channel. Affected file is
3561 silcd/packet_receive.c.
3563 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3565 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3566 which is given as argument to the silc_client_alloc now.
3567 It can be used to configure the client and set various parameters
3568 that affect the function of the client.
3570 * The USERS command in server did not check whether the channel
3571 is private or secret. Affected file silcd/command.c.
3573 * Added new argument to the USERS command in protocol specification.
3574 The USERS command now can take the channel name as argument
3575 as well. Added support for this in client and server and
3576 updated the protocol specs.
3578 * Completed the GETKEY command in client. It can be now used
3579 to fetch also servers public key not only some clients.
3580 Affected files lib/silcclient/command[_reply].c.
3582 * Added silc_client_get_server to return server entry by the
3583 server name. Affected files lib/silcclient/silcapi.h and
3586 * Redefined the IDENTIFY command in protocol specification to be
3587 more generic. It now can be used to query information about
3588 any entity in the SILC Network, including clients, servers and
3589 channels. The query may be based either the entity's name
3590 or the ID. Added support for this in both client and server.
3592 Affected files silcd/command.c and lib/silcclient/command.c
3593 and command_reply.c.
3595 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3596 the _from_client and _from_server functions. Affected file
3599 * Added silc_client_get_channel_by_id_resolve to the file
3600 lib/silcclient/silcapi.h to resolve channel information by
3601 its ID. Added also silc_client_get_channel_by_id that
3602 does not resolve it from the server.
3604 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3606 * Added SilcServerEntry context into the client library
3607 to represent one server. The INFO command now allocates
3608 these to save the resolved server info. For now on the
3609 client library will also keep information about servers,
3610 connected and resolved with INFO.
3612 The INFO command now allocates the SilcServerEntry context
3613 and saves the server info there. The COMMAND_REPLY in
3614 the INFO now returns the parameters to application in
3615 same order as defined in the protocol specification.
3617 The entries are cached in the client->server_cache.
3619 * The INFO command is now issued after received the Client ID
3620 from the server. Affected file lib/silcclient/client.c.
3622 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3623 to the application as the mode changer might be server.
3624 It is guaranteed that NULL is not returned anymore to the
3625 application. Affected file lib/silcclient/client_notify.c.
3627 The ID Type is now also passed to the application so that
3628 it can check whether the returned entry is SilcClientEntry
3631 Added new function silc_client_get_server_by_id to return
3632 the server entry by ID. Affected files are the
3633 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3635 * Do not create the channel in the Irssi SILC Client when issuing
3636 the JOIN command but when received the sucessful JOIN command
3637 reply. Otherwise the channel might get created even though we
3638 could not join it. The Affected file is
3639 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3641 * Fixed a channel joining bug in router. The router must also
3642 check the channel modes, invite and ban lists etc. when serving
3643 the JOIN command sent by normal server. Affected file is
3644 silcd/command.c. The router now resolves the client's
3645 information from the server who sent the JOIN command if it
3646 does not know it, and processes the JOIN command only after
3649 * Changed the SilcCommandCb to take new argument; void *context2.
3650 Affected file lib/silccore/silccommand.h
3652 The second argument in the command callbacks in the server now
3653 includes the SilcServerCommandReplyContext if the command was
3654 called as pending command callback from the command reply.
3655 Otherwise it is NULL. When called as pending the status of the
3656 command reply will be checked and if it was erronous the
3657 error will be sent to the original sender of the command.
3658 This way the client always receives the error messages even
3659 though the server was actually the one who received the error
3660 when it resent the command to router, for example. Affected
3661 files silcd/command[_reply].[ch].
3663 * Fixed sending WHOWAS command's error message to client if
3664 the requested client could not be found. It was missing.
3667 * Changed the CMODE and CUMODE commands reply arguments in the
3668 protocol specification. The Channel ID is now sent in both
3669 of the commands to identify the channel. Implemented this
3670 new feature to the client and server. Affected files
3671 lib/silcclient/command_reply.c and silcd/command.c.
3673 * Made better checks for invite and ban lists in the JOIN
3674 command in server. Affected file silcd/command.c.
3676 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3678 * The server now performs the incoming host IP/DNS lookup
3679 using the silc_socket_host_lookup and thus does not block
3680 the server anymore. Affected file silcd/server.c.
3682 * Completed the multi-thread support for SILC Scheduler in
3683 the lib/silcutil/silcschedule.c.
3685 * Fixed the configure.in.pre to detect the pthread correctly
3688 * Fixed a deadlock in silc_task_queue_wakeup in the file
3689 lib/silcutil/silctask.c.
3691 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3693 * Added new function silc_schedule_wakeup that is used in
3694 multi-threaded environment to wakeup the main thread's
3695 schduler. It needs to be used when a thread adds a new task
3696 or removes a task from task queues. After waking up, the
3697 scheduler will detect the task queue changes. If threads
3698 support is not compiled in this function has no effect.
3699 Implemented the wakeup mechanism to both Unix and WIN32
3700 systems. Affected files are lib/silcutil/silcschedule.[ch],
3701 lib/silcutil/unix/silcunixschedule.c and the
3702 lib/silcutil/win32/silcwin32schedule.c.
3704 * Added new function silc_task_queue_wakeup to wakeup the
3705 scheduler by the specified task queue. Affected file
3706 lib/silcutil/silctask.[ch].
3708 * The silc_socket_host_lookup_start now wakes up the scheduler
3709 after adding the timeout task. Affected file is
3710 lib/silcutil/silcsockconn.c.
3712 * The silc_socket_host_lookup is synchronous now if the threads
3713 support is not compiled in. However, the callback is still
3714 called asyncronously through the scheduler, anyway. Affected
3715 file lib/silcutil/silcsockconn.c.
3717 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3719 * Added new function silc_socket_host_lookup to perform
3720 asynchronous IP and FQDN lookups for the socket connection.
3721 Affected files lib/silcutil/silcsockconn.[ch].
3723 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3725 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3726 that may or may not compile the mutex support in.
3728 Changed the silc_mutex_alloc interface. It allocates the
3729 mutex now to the sent pointer and returns TRUE or FALSE.
3731 Affected file lib/silcutil/silcmutex.h.
3733 * Wrote the SILC Task Queue interface to support multi-threads.
3734 Affected file lib/silcutil/silctask.[ch].
3736 * Wrote the SILC Scheduler to support multi-threads. Affected
3737 file lib/silcutil/silcschedule.c.
3739 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3741 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3742 in lib/silcutil/win32/.
3744 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3746 * Defined SILC Mutex API and SILC Thread API and implemented
3747 them for Unix. Affected files are
3748 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3749 lib/silcutil/unix/silcunixmutex.c and
3750 lib/silcutil/unix/silcunixthread.c.
3752 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3754 * Fixed the silc_server_remove_clients_by_server's channel
3755 key re-generation. The hash table handling was incorrect
3756 and would not work with many channels. Affected file is
3759 * Fixed some memory leaks around the server code.
3761 * Rewrote the silc_server_get_users_on_channel to support IPv6
3762 based Client ID's. Affected file silcd/server.c.
3764 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3765 specification. However, a separate document must be written
3766 to define the detailed signing procedure and the payload
3767 associated with the flag. Defined the flag to the
3768 lib/silccore/silcchannel.h as well.
3770 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3772 * Changed the dynamic tables to static size tables in the
3773 lib/silccrypt/silchmac.c.
3775 * Removed GCC dependencies from the code. A patch by cras.
3777 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3779 * Do not show the error "Error receiving packet bla bla"
3780 in server if it really was not an error (-2 means that reading
3781 is pending). Affected file silcd/server.c.
3783 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3785 * Fixed a possible crash in silc_server_remove_clients_by_server
3786 in silcd/server.c. Fixed there also some memory leaks.
3788 * Fixed the silc_idlist_replace_client_id. It could replace
3789 wrong key in the hash table. Affected file silcd/idlist.c.
3791 * Do not check whether there are global users on the channel
3792 if the channel->global_users is FALSE. Affected functions
3793 silc_server_remove_from_one_channel and
3794 silc_server_remove_from_channels in silcd/server.c. Also,
3795 do not check if the removed client is local as we can be
3796 sure that global client was not removed from the channel
3797 and checking for global users is not needed.
3799 * The silc_server_remove_clients_by_server now re-generates
3800 the channel keys correctly for those channels that had
3801 clients removed from them. Affected file silcd/server.c.
3803 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3805 * Found the reason of random crashes in the server. We weren't
3806 ignoring the SIGPIPE signal (which can be sent in write())
3807 and it crashed the server. Affected file silcd/silcd.c.
3809 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3811 * Assure that sock->user_data is not NULL in the function
3812 silc_server_packet_send in silcd/packet_send.c.
3814 * Disconnect the remote connection if it could not be added
3815 to any ID lists in the server. The affected file is
3818 * Check in silc_server_packet_send[_real/dest] that the
3819 socket is not disconnecting and ignore the data if it is.
3820 Affected file silcd/packet_send.c.
3822 * Define inline to __inline on native WIN32 compilation.
3823 Affected file includes/silcwin32.h.
3825 * Added some explicit type casts for inline code since MSVC
3826 require them. Affected files lib/silcutil/silcbuffer.h,
3827 lib/trq/silcdlist.h and lib/trq/silclist.h.
3829 * Print warning in log files from now on if the packet
3830 decryption fails. Affected file silcd/server.c.
3832 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3834 * Changed the `say' client operation's interface to accept
3835 new `type' argument to indicate the type of the message sent
3836 by the library. The application may filter the library's
3837 messages according the type. The affected file is the
3838 lib/silcclient/silcapi.h.
3840 * Added two new functions to lib/silcclient/silcapi.h:
3841 silc_client_del_client and silc_client_del_client_by_id.
3842 Affected file lib/silcclient/idlist.c.
3844 * Moved the clientincludes.h from includes/ to silc/ and
3845 serverincludes.h from includes/ to silcd/.
3847 * The modes for the CMODE and CUMODE are now passed as
3848 uint32 for application with COMMAND_REPLY. The affected
3849 file is lib/silcclient/command_reply.c.
3851 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3853 * /WHOIS without arguments shows client's own information.
3854 Affected file lib/silcclient/command.c.
3856 * Changed PING to not accept any arguments. The specs
3857 says that client can ping only the connected server so
3858 requiring an argument is not needed. Affected file is
3859 lib/silcclient/command.c.
3861 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3863 * Fixed a fatal bug in private message sending and reception
3864 encryption and decryption when using private message keys.
3865 The implementation was incorrect and did not follow the
3866 specification. It causd that some of the message were
3867 lost since it did not use the sending and receiving keys
3868 as the protocol suggests. This has been fixed and will cause
3869 incompatibilities with older clients when sending private
3870 message encrypted with private message keys. Affected files
3871 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3872 and various other in Irssi SILC Client.
3874 Added `responder' boolean argument to the functions
3875 silc_client_add_private_message_key[_ske] to indicate when
3876 the key is added as responder or initiator of the key
3879 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3881 * Removed the silc_ske_check_version function and created
3882 a SilcSKECheckVersion callback. Added also a function
3883 silc_ske_set_callbacks that is now used to set all SKE
3884 callbacks. The callback functions are not given to
3885 the SKE functions anymore, but this function is used to
3888 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3890 * Added `silc_version' argument to the silc_client_alloc
3891 to define the version of the application for the library.
3892 The library will use the version string to compare it
3893 against the remote host's (usually a server) version
3894 string. Affected file lib/silcclient/silcapi.h
3896 * Added the KE protocol context to Key Agreement context
3897 in client library so that we can abort the SKE if it
3898 is in process when we get timeout. Affected file is
3899 lib/silcclient/client_keyagr.c.
3901 * Do not resolve the client ID forever if it returns in the
3902 first time that such client does not exist. This was done
3903 for example with private message. Affected file is
3904 lib/silcclient/client_prvmsg.c.
3906 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3908 * Do not add regex.h for WIN32. The affected file
3909 includes/silcincludes.h.
3911 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3912 not work yet 100%. It generates the DLL's automatically
3913 when compiling with --with-win32 under cygwin.
3915 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3917 * lib/contrib/regex.c is not compiled on WIN32.
3919 * Added silc_net_get_socket_opt function to the
3920 lib/silcutil/silcnet.h.
3922 * Added includes/silcwin32.h for WIN32 specific includes
3925 * Do not use ptime structure or any of the posix process
3926 functions on WIN32 in lib/silccrypt/silrng.c.
3928 * Added silc_gettimeofday to provide generic function
3929 for struct timeval on all platforms. Added the function
3930 to lib/silcutil/silcutil.h.
3932 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3934 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3935 library as they clearly belong there. As a plus side we
3936 can make the actual socket connection routines platform
3939 Added also new generic function silc_socket_read and
3940 silc_socket_write (that used to be silc_packet_[read/write].
3941 The implementation of these are platform specific.
3943 * Added WIN32 specific routines of silc_socket_[read/write]
3944 to lib/silcutil/win32/silcwin32sockconn.c.
3946 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3948 * Added preliminary support for native WIN32 compilation under
3949 cygwin (using the -mno-cygwin option for GCC) to the
3950 ./configure.in.pre. The --with-win32 now prepares the
3951 compilation for native WIN32.
3953 * Rewrote the SILC Scheduler interface in the file
3954 lib/silcutil/silcschedule.h. The scheduler is now context
3955 based and does not have anymore any global static scheduler.
3956 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3957 and created lib/silcutil/win32 directory for WIN32 based
3960 * Added Unix specific network routines to the
3961 lib/silcutil/unix/silcunixnet.c and the old
3962 lib/silcutil/silcnet.c includes now only generic routines.
3964 Added WIN32 specific network routines to the
3965 lib/silcutil/win32/silcwin32net.c.
3967 * Added Unix specific utility functions from the
3968 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3970 * Added WIN32 SILC Scheduler to the file
3971 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3974 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3976 * Do not handle JOIN notify in the server if the target client
3977 is not registered (idata->registered == FALSE). The affected
3978 file is silcd/packet_receive.c.
3980 * Update the nickrec->founder in event_cumode in the Irssi SILC
3981 client. Affected file irssi/src/silc/core/silc-channels.c.
3983 * Fixed the CUMODE_CHANGE notify handling in the server when
3984 server and router are announcing their clients on channels.
3985 Now the mode changes are saved and notified correctly. The
3986 affected file is /silcd/packet_receive.c.
3988 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3989 They really did not replace the cache entry in the ID Cache.
3990 Now they do that. Affected file silcd/idlist.c.
3992 * Fixed the KICK notify handling in the Irssi SILC client to
3993 update the channel records so that the kicked client does not
3994 appear to be on the channel. The affected file is
3995 irssi/src/silc/core/silc-channels.c.
3997 * Always update the conn->current_channel when executing command
3998 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
4000 * Fixed the KILL notify handling in Irssi SILC client to remove
4001 the killed client on all channels.
4003 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4005 * Fixed the silc_parse_command_line to remove extra spaces
4006 from the start and end of the arguments. Affected file is
4007 lib/silcutil/silcutil.c.
4009 * Cancel and free any active protocol in the function
4010 silc_server_close_connection. Affected file silcd/server.c.
4012 * Cancel and free any active protocol in the function
4013 silc_client_close_connction. Affected file is
4014 lib/silcclient/client.c.
4016 * Do not execute the KILL command for clients that are in
4017 history (ie. they are not in the network). Affected file is
4020 * Fixed KILL notify handling, client does not crash anymore.
4021 Affected file irssi/src/silc/core/silc-channels.c.
4023 * Reduced the default packet buffer size from 2048 to 1024 in
4024 lib/silccore/silcpacket.c.
4026 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
4027 counter to the SKE context that is incresed when the SKE library
4028 performs async operation outside the library. If the outside
4029 process frees the SKE context and FREED status will be set
4030 and the library will detect after the sync operation that the
4031 libary is freed. The affected files are
4032 lib/silcske/silcske[_status].[ch].
4034 * Resolve the client entry information in the function
4035 silc_client_channel_message to assure that NULL pointer is not
4036 passed as client entry to the application. */
4038 * Fixed the task timeout calculation to assure that there is
4039 never negative timeouts. The affected file is
4040 lib/silcutil/silcschedule.c.
4042 * Fixed the channel user mode notification sending in server.
4043 It was sent point-to-point to the router (or to server by router)
4044 but it needs to be destined to a channel. The routines now
4045 supports sending the channel user mode notifys to the channels
4046 when announcing clients and channels. Affected files are
4047 silcd/server.c and silcd/packet_receive.c.
4049 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4050 It did not actually replace the old channel entry in the cache.
4051 Affected file lib/silcclient/client_notify.c.
4053 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4055 * Fixed a possible crash in silc_packet_send_prepare. It now
4056 assures always that there is enough space in the buffer and
4057 at the tail area of the buffer (for MAC).
4059 Fixed the inbound buffer reallocation in silc_packet_read.
4060 It was old code and did not handle the reallocation correctly.
4063 The affected file is lib/silccore/silcpacket.c.
4065 * Fixed buffer overflow in silc_parse_nickname in the file
4066 lib/silcutil/silcutil.c.
4068 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4070 * make install generates new server keys only if there is not
4073 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4075 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4076 Added check that if the NOREPLY is set then we will not send
4077 the away message. This avoids infinite loop of away messages
4078 if both clients are away. The affected file is
4079 lib/silcclient/client_prvmsg.c.
4081 * Fixed client crash if /NICK was given without arguments.
4082 Affected file lib/silcclient/command.c.
4084 * Server does not send the invite list in INVITE command back
4085 to the client if the list was not altered. Added this notion
4086 to the protocol spec as well. Affected file silcd/command.c.
4088 Fixed possible crash in INVITE command by checking the
4089 value of silc_server_get_client_route command.
4091 * Fixed the INVITE notify type handling. The arguments are now
4092 taken in correct order and client does not crash. The affected
4093 file is irssi/src/silc/core/silc-channels.c.
4095 Removed the "Inviting xxx to channel" message from the
4096 client library away and let the application handle it.
4097 Affected file lib/silcclient/command.c. Added that message
4098 to Irssi SILC client's message formats.
4100 * Fixed CMODE command crash in client. It now checks the
4101 amount of arguments correctly and does not crash. The affected
4102 file is lib/silcclient/command.c.
4104 * Do not create new channel automatically in silc_channels_join
4105 but check whether the channel by that name already exists.
4106 Affected file irssi/silc/core/silc-channels.c.
4108 * Do not send the SERVER_SIGNOFF to router if the disconnected
4109 entity was the router. Affected file silcd/server.c.
4111 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4112 SILC client as it was missing from there.
4114 Added the handling of the KICK notify to the Irssi SILC client
4115 as it was missing. Added "you have been kicked" message to
4116 Irssi SILC client's message modules formats.
4118 Added the handing of the KILL notify to the Irssi SILC client
4119 as it was missing. Added the kill message module formats
4122 The affected file is irssi/src/silc/core/silc-channels.c.
4124 * The router did not save the channel mode the server announced.
4125 Affected file silcd/packet_receive.c.
4127 * Fixed a possible crash in INFO command in server. If the
4128 server did not provide the server info it crashed. Affected
4129 file silcd/command.c.
4131 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Fixed the GETKEY command in the server to check also the
4134 global list. Otherwise the GETKEY would not work correctly
4135 in normal SILC server. Affected file silcd/command.c.
4137 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4139 * Fixed GETKEY crash, it crashed if the command did not succseed.
4141 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4143 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4144 is now real and not just an macro interface to GMP.
4146 Removed the entire GMP from the source tree and imported new
4147 NSS MPI library instead. Reason for removing GMP is that it is
4148 extremely large and compiles extremely slow. The NSS MPI
4149 is only a few files and compiles in less than 10 seconds.
4150 The speed is also about the same as GMP. The MPI is imported
4151 to lib/silcmath/mpi.
4153 If the system has GMP installed we will still use the GMP.
4154 If it is not then the NSS MPI will be compiled.
4156 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4158 * Merged a long nickname (127 characters long) crash bugfix from
4159 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4161 * Merged a freed memory reference bugfix from Irssi CVS tree.
4162 Affected file irssi/src/core/commands.c.
4164 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4166 * Added the server's public key sving and verification to the
4167 server when performing the SKE. This was missing and the
4168 remote server's (or router's) public key was accepted without
4169 checking whether we have it previously or trust it at all.
4170 Affected file silcd/protocol.c.
4172 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4174 * Check in the silc_server_timeout_remote if protocol is active
4175 and make sure that the protocol's final callback is called so
4176 that all memory if freed. Affected file silcd/server.c.
4178 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4180 * silc_server_whois_send_reply crashed the server if the nickname
4181 was 127 characters long. Affected file silcd/command.c.
4183 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Added sanity check to the silc_server_new_client. If the hostname
4186 is provided inside username then check that the provided hostname
4187 really is the same as the resolved one. If the hostname was not
4188 resolved then check it from the public key. Affected file is
4189 silcd/packet_receive.c.
4191 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4192 if the server disconnected us and the connection is not valid
4193 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4195 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4196 the library to the lib/silcutil/silcutil.[ch].
4198 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4200 * Close log file after open. Affected file
4201 lib/silcutil/silclog.c.
4203 * Check whether sock == NULL in silc_client_send_packet and return
4204 if it is. Affected file lib/silcclient/silcclient.c.
4206 * Check rec->entry == NULL in the Irssi SILC Client before
4207 sending the channel message. Affecte file is
4208 irssi/src/silc/core/silc-servers.c.
4210 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4212 * Merged a splitted window bugfix from Irssi CVS tree. The
4213 affected file is irssi/src/fe-text/textbuffer-view.c.
4215 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4216 It did not print nickname.
4218 * Improved the distributions system a bit.
4220 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4223 irssi/src/fe-text/gui-window.c.
4225 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4226 to in-active server. The affected file is
4227 irssi/src/silc/core/client_ops.c.
4229 * Resolve the client in USERS command reply if the entry does
4230 not have username resolved. The affected file is
4231 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4232 command to WHOIS command to really resolve stuff. The USERS
4233 is not used any more in any critical section so WHOIS can
4234 be used even though it might be slower than IDENTIFY.
4236 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4239 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4241 * Changed the protocol API a bit more consistent in the
4242 lib/silccore/silcprotocol.[ch].
4244 * Changed the following headers to ROBODoc format:
4246 lib/silccore/silcpayload.h
4247 lib/silccore/silcprotocol.h
4248 lib/silccore/silcsockconn.h
4250 All core library headers are now formatted.
4252 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4254 * Fixed a bug in Irssi SILC client; do not show that you are
4255 server/router operator if you really are not. Affected file is
4256 irssi/src/silc/core/client_ops.c.
4258 * Renamed silc_command_free_payload to silc_command_payload_free.
4259 Affected file lib/silccore/silccommand.h
4261 * Added silcmath.h to include the prototoypes of various routines
4262 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4265 * Changed the following headers to ROBODoc format:
4267 lib/silccore/silcchannel.h
4268 lib/silccore/silccommand.h
4269 lib/silccore/silcid.h
4270 lib/silccore/silcidcache.h
4271 lib/silccore/silcmode.h
4272 lib/silccore/silcnotify.h
4273 lib/silccore/silcpacket.h
4274 lib/silcmath/silcmath.h
4276 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4278 * Added checking to the server code not to start the server if
4279 ciphers and stuff are not configured properly. Affected files
4280 silcd/serverconfig.[h] and silcd/server.c.
4282 * Changed the layout of the header files of the public interfaces
4283 in the SILC libraries. The new layout supports ROBODoc
4284 documentation tool (and some others) so that it is easy to create
4285 a library reference manual. All the other headers and source
4286 code must still follow the CodingStyle document. Also source
4287 code must not include these ROBODoc stuffs, only the headers.
4288 Furthermore, all public interface headers must now be named
4289 by using `silc' prefix, example: silcapi.h, silccipher.h.
4290 Some files were renamed due to this. All the other headers
4291 must not be used as public interfaces. I will update the
4292 CodingStyle document later. Changed following headers, so far:
4294 lib/silcclient/silcapi.h
4295 lib/silccore/silcauth.h
4296 lib/silccore/silcprivate.h
4297 lib/silccrypt/silcdh.h
4299 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4303 * Removed silc_client_packet_send_flush from the client library
4304 as it is not needed. Affected file lib/silcclient/client.[ch].
4306 * Added printing of message of unresolved authentication method
4307 to the Irssi SILC client. Added it to the module formats.
4308 Removed the same message from the client library.
4310 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * Added new distribution feature, DISTLABEL. Every distribution
4313 can define own preprocessor label that can be used in the
4314 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4315 file distributions, acconfig.h.pre and prepare.
4317 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Added Makefile.defines_int to include the actual definitions
4320 for Makefile.defines.in. Tested the new distribution system,
4321 created distributions and tested installation.
4323 * Added AWAY message printing to the Irssi SILC client. Added
4324 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4326 * Added SCONNECT command to call the SILC's CONNECT command.
4327 Cannot use CONNECT directly since Irssi uses that internally.
4328 Affected file irssi/src/silc/core/silc-servers.c.
4330 Added ACTION local command. It is same as ME command but takes
4331 the channel as mandatory argument.
4333 Rewrote some of the Irssi's help files to suite for SILC
4336 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4338 * Added Makefile.defines[.in] that should for now on be included
4339 in all Makefile.am file in the source tree. That file includes
4340 all common compilation definitions for SILC source tree.
4342 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4344 * Minor changes to the ./prepare script to change the package
4345 name according the distribution name to the configure.in.
4347 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4349 * Created new distribution system. Added file `distributions'
4350 that defines all the distributions that can be created out of
4351 the SILC source tree. The ./prepare script now reads that
4352 file to determine how to prepare the distributions. The
4353 first argument to the ./prepare is the name of the distribution
4354 and second is the version of the distribution. If given
4355 without arguments it creates the default (toolkit) distribution
4356 with the default version (defined in ./prepare).
4358 All Makefile.am files that are subject to the distributions
4359 are now named as Makefile.am.pre. These are ./Makefile.am
4360 and lib/Makefile.am. Others may be changed later.
4362 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4364 * Added invite list, ban list, some key management and connection
4365 error message printing to module formats in the Irssi SILC client.
4367 * Added new silc_client_set_away_message to set the away message
4368 that is back to the person who sent private message. The
4369 affected file lib/silcclient/silcapi.h and the
4370 lib/silcclient/client_prvmsg.c.
4372 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4374 * Fixed the private message sending in the Irssi SILC client,
4375 added local command KEY to the Irssi SILC client.
4377 Added key management and key agreement message formats to the
4378 irssi/src/fe-common/silc/module-formats.[ch].
4380 Added USERS (alias WHO) printing, server/router operator
4381 indication and LIST command printing to the module formats.
4383 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Fixed channel joining notify handling, cumode notify handling
4386 from Irssi SILC client.
4388 * Added SILC specific module-formats to the Irssi SILC client so
4389 that SILC specific message hilighting, colors etc is possible.
4390 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4392 Added channel mode, channel user mode, actions, notices,
4393 whois and whowas printing to the the module-formats.c.
4395 * Fixed a bug in channel deletion in the server. The channel
4396 is not left to the cache even if the channel founder auth mode
4397 is set when there are no users anymore on the channel. Affected
4398 file silcd/server.c.
4400 * The silc_net_localhost now resolves the entire hostname including
4401 the domain name. Affected file lib/silcutil/silcnet.c.
4403 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4405 * Changed the ask_passphrase client operation to be ascynchronous.
4406 It has now a completion callback and a context that the
4407 application must call after it has got the passphrase from
4408 the user. Affected files lib/silcclient/silcapi.h,
4409 lib/silcclient/protocol.c, lib/silcclient/command.c and
4412 Added SilcAskPassphrase callback that the application calls
4413 to deliver the passphrase to the library.
4415 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4416 The public key verification and especially a certificate
4417 verification is asynchronous procedure.
4419 Added new SILC_SKE_STATUS_PENDING status to indicate the
4420 request is pending and a callback will be called to finalize
4423 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4424 indicate that remote end did not send its public key (or
4425 certificate), even though we require it. Added check for this
4426 condition in the SKE. This was a security bug, now fixed.
4428 Defined new SilcSKEVerifyCbCompletion callback that is called
4429 when the verification process is completed.
4431 The affected files lib/silcske/silcske_status.h and
4432 lib/silcske/silcske.[ch].
4434 * Changed the verify_public_key client operation to be async
4435 as well. Defined SilcVerifyPublicKey callback that is used to
4436 indicate the success of the public key verification process.
4438 Changed the server and client to use the new async client
4441 * Changed the Irssi SILC client's internal scheduler to be called
4442 twice as many times as it used to be. As a result the client
4443 should be a bit faster now. Affected file is
4444 irssi/src/silc/core/silc-core.c.
4446 * Added support to Irssi SILC client of asynchronous public key
4447 verification and passphrase inquiry. Affected file is
4448 irssi/src/silc/core/silc-core.c.
4450 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4452 * Do not say "You have left channel %s" in client library.
4453 Moved it to the application. Affected files are
4454 lib/silcclient/command.c and silc/client_ops.c.
4456 * Fixed silc_client_get_clients. Command context was not
4457 duplicated and was freed memory in the callback. Affected
4458 file lib/silcclient/idlist.c.
4460 * Do not say "you are now talking..." on JOIN command in the
4461 client library. The appliation must handle it.
4463 * Do not say ".. changed topic to" in command reply in the
4464 client libary. The application must handle it.
4466 * Fixed TOPIC command sending in the client library.
4468 * Fixed a memory leak in silc_client_command_free in the file
4469 lib/silcclient/command.c.
4471 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4473 * Imported a modified version of Irssi client to the source tree.
4474 The Irssi will be used to create a new client called
4475 Irssi SILC. Imported to irssi/.
4477 Added silc_core_init_finish function to the Irssi. Affected
4478 file irssi/configure.in.
4480 A lot changes in the Makefile.ams around the irssi tree.
4482 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4484 * Do not rehash if the new size is same as the old size of the
4485 hash table, in the silc_hash_table_rehash*. The affected file
4486 lib/silcutil/silchashtable.c.
4488 * Replaced hash_table_del_by_context calls from the server
4489 (when channel->user_list and client->channels) to the
4490 hash_table_del as it is sufficient and faster.
4492 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4494 * Added silc_hash_table_list, silc_hash_table_get and the
4495 SilcHashTableList structure to provide an alternative way to
4496 traverse the hash table. The affected files are
4497 lib/silcutil/silchashtable.[ch].
4499 * Changed the server's idlist routines to use the hash table
4500 routines to optimize the code.
4502 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4504 * Replaced the client entry's `channel' list and channel entry's
4505 `user_list' list to hash tables for optimized lookup. Changed
4506 the code to use the hash table interface around the code.
4507 Affected file lib/silcd/idlist.[ch].
4509 * Added `auto_rehash' boolean argument to the function
4510 silc_hash_table_alloc to indicate whether the hash table should
4511 auto-rehash when it thinks is appropriate time. It will
4512 increase the hash table size if the there is twice as much
4513 entries in the table than the size of the table, and will
4514 decrease the size if there are twice as less entries than
4515 the size of the table.
4517 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4519 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4521 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4523 * silc_idcache_purge_by_context deletes the entry now by context
4524 as it is supposed to do. Affected file lib/silccore/idcache.c.
4526 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4527 client is not anymore valid (WHOWAS givens the info) and not
4528 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4530 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4532 * Removed the `data' and `data_len' arguments from the ID Cache
4533 interfaces and added `name' argument. ID Cache does not handle
4534 anymore the binary data only a names associated with given ID.
4536 * When hashing a Client ID with silc_hash_id the entire ID is
4537 not hashed anymore, instead only the hash of the Client ID is
4538 hashed. This way we can access the Client ID from the cache
4539 with Client ID but with the hash of the ID (which is a hash of
4540 the nickname) as well without any difference in performance.
4542 Added also silc_idcache_find_by_id_one_ext to do one on one
4543 searching when we have the actual ID. Added also function
4544 silc_hash_client_id_compare. The affected files are
4545 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4547 * When hashing the name associated with a ID it is always done
4548 in lowercase. This way we can access the cache without worrying
4549 about case-sensitivity, even though, for example nicknames are
4552 * Fixed a bug in server with channel message sending. It put
4553 wrong ID type as destination ID. The affected file
4554 silcd/packet_send.c.
4556 * silc_idcache_del_by_context now deletes from all hash tables
4557 by context. Affected file lib/silccore/idcache.c.
4559 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4561 * Changed the client library to use the new ID Cache interface.
4562 Changes around the source tree.
4564 * Added silc_hash_table_rehash_ext to rehash with specific
4565 hash function. Affected file lib/silcutil/silchashtable.[ch].
4567 * Added silc_hash_string_compare to compare two strings in the
4568 hash table. Affected file lib/silcutil/silcutil.[ch].
4570 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * Added new function silc_idcache_del_by_context into the
4573 lib/silccore/idcache.[ch].
4575 * Changed the server's ID list routines to use the new ID Cache
4576 interface. Changes around the source tree.
4578 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4580 * Added silc_hash_table_del[_by_context]_ext functions in to the
4581 lib/silcutil/silchashtable.[ch].
4583 Removed silc_hash_table_find_all* routines and added new
4584 silc_hash_table_find_foreach to replace them.
4586 Added silc_hash_table_replace_ext function as extended
4587 replacing function. Separated the simple hash table interface
4588 from the extended hash table interface in the file
4589 lib/silcutil/silchashtable.h.
4591 * Fixed minor bugs and changed it to use some of the new
4592 hash table functions in lib/silccore/idcache.c
4594 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4596 * Added new function silc_hash_table_find_all to return all keys
4597 in the hash table by the specified key. As the hash table is
4598 collision resistant it also makes it possible to have several
4599 duplicate keys in the hash table. This function may be used to
4600 find all of the keys from the hash.
4602 Added user_context arguments to the SilcHashFunction,
4603 SilcHashCompare and SilcHashDestructor to deliver user specified
4606 Added new fuctions silc_hash_table_find[_all]_ext to do
4607 extended lookup with specified hash and compare functions and
4608 specified user contexts.
4610 Added new function silc_hash_table_add_ext to add the key
4611 with specified hash function and user context.
4613 Added new function silc_hash_table_foreach to traverse all
4614 entrys in the hash table. Added SilcHashForeach callback
4617 Added new function silc_hash_table_del_by_context to delete
4618 the entry only if the context associated with the key matches.
4620 Affected files are lib/silcutil/silchashtable.[ch].
4622 * Removed silc_hash_[server/client/channel]_id and added just
4623 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4624 silc_hash_id_compare to compare two ID's using as the hash table
4625 comparison function. Added also silc_hash_data to hash
4626 binary data and silc_hash_data_compare to compare it.
4628 * Removed silc_idlist_find_client_by_hash as it is not needed
4629 anymore. Affected file silcd/idlist.[ch].
4631 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4632 to use internally the SilcHashTable. The new ID Cache is a lot
4633 faster than the old one. Some of the ID Cache interface was also
4634 rewritten and obsolete and stupid functions were removed.
4636 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Added entry_count field to the SilcHashTable to keep the number
4639 of the entries in the table. Implemented the function
4640 silc_hash_table_rehash. Added new function
4641 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4643 Fixed a minor bug in silc_hash_table_free.
4645 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4646 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4647 into the lib/silcutil/silcutil.[ch].
4649 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4651 * Implemented a collision resistant hash table into the
4652 lib/silcutil/silchashtable[ch]. See the header and the source
4653 for the SilcHashTable API.
4655 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Merged dotconf version 1.0.2 into lib/dotconf.
4659 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4661 * Do not compile anything in lib/silcsim/* if the SIM support
4662 is not enabled. The tree should now compile without problems
4665 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4667 * Compiled the SILC under cygwin. Compiled and tested briefly
4668 without problems. More tests needed. The SIMs didn't compile
4671 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4673 * Fixed possible crash in silc_get_username in the
4674 lib/silcutil/silcutil.c.
4676 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4678 * Fixed a va_arg in silc/client_ops.c.
4680 * Oops, RC5 routines were named AES and caused some problems
4681 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4683 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4685 * Added new SilcIDIP structure into the lib/silccore/id.h and
4686 replaced the old `ip' fields from all SILC ID's to that type.
4687 This is a step towards IPv6 support.
4689 The silc_id_get_len takes now the ID as an extra argument.
4690 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4691 both IPv4 and IPv6 based ID's.
4693 The affected files are lib/silccore/id.[ch] and other files
4694 around the tree using these routines.
4696 * Removed the ID length arguments in server from various
4697 silc_server_send_notify_* routines -> they are not needed
4700 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4702 * Fixed memory leak in silc_encode_pem_file in the file
4703 lib/silcutil/silcutil.c.
4705 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4707 * Check minor version as well in the SKE. Affected files are
4708 silcd/protocol.c and lib/silcclient/protocol.c.
4710 * Added --identifier option to the server so that an identifier
4711 can be when creating the public key for the server. Affected
4712 file is silcd/silcd.c.
4714 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4715 lib/silccrypt/silcpkcs.c.
4717 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4719 * Register default ciphers and stuff when using -C option with
4720 the server. Affected file sildc/silcd.c.
4722 * Put back the servers public key filename format, it is better
4723 than the new one. For now, the client keys are saved with the
4724 new filename format. The affected file silc/client_ops.c.
4726 * Implemented the Cipher API for the rest of the ciphers that
4727 did not implement it or implemented it the wrong way.
4729 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4731 * Register default ciphers and stuff when using the -S option
4732 in the client. Affected file silc/silc.c. Same also when
4733 creating new key pair with -C option.
4735 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4737 * Fixed the silc_verify_public_key client operation function to
4738 save the public keys differently. The fingerprint is now
4739 used as filename and not the hostname. This way also the
4740 client keys are saved uniquely and not with hostnames. The
4741 affected file is silc/client_ops.c.
4743 * Trimmed the silc_hash_fingerprint function to remove extra
4744 whitespaces from the end of the fingerprint. The affected
4745 file is lib/silccrypt/silchash.c.
4749 * Added silc_cipher_register_default function to register all
4750 default ciphers. It can be used when configuration files
4751 does not exist and the application does not want any specific
4752 ciphers in any specific order.
4754 The SilcDList is now used as silc_cipher_list dynamically
4755 allocated cipher list. Removed the static list all together
4756 and now all ciphers must be allocated to the dynamic list.
4757 The silc_cipher_alloc routine was changed to check only the
4760 All silc_cipher_* routines that used to return int returns
4763 The affected files lib/silccrypt/silccrypt.[ch].
4765 * The same thing was done to silc_hash_* as for silc_cipher_*
4766 routines. Affected files lib/silccrypt/silchash.[ch].
4768 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4769 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4770 Added also silc_pkcs_[un]register[_default] functions.
4771 Removed the data_context from the PKCS API.
4773 * Added silc_hmac_register_default function to register default
4774 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4775 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4776 to unregister all hmacs at once.
4778 * Register the default ciphers, hash functions, PKCSs and HMACs
4779 if client's configuration file does not exist. The affected
4782 * The client did not load the hash functions from the SIM
4783 modules at all. Added support for this. Affected file is
4784 silc/clientconfig.c.
4786 * When decoding public key with silc_pkcs_public_key_decode, check
4787 the supported algorithm only if PKCS are registered. Affected
4788 file lib/silccrypt/silcpkcs.c. The same was done with the
4789 silc_pkcs_private_key_decode.
4791 * Fixed the SILC List routines to keep the list always in order.
4792 It used to change the list's order when traversing the list but
4793 not it preserves the order. Affected file lib/trq/silclist.h.
4795 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4797 * Added the client library to use the SilcSocketConnection's
4798 reference counter (by silc_socket_dup) to prevent the bug that
4799 the socket object may be freed underneath async operation.
4801 * The name resolv library checking fixes in the configure.in.pre.
4804 * Created new version of the protocol drafts for future
4805 development. The -03 drafts are the ones that will be changed
4806 in the trunk now and the -02 will remain as they are.
4808 * Send list of CUMODE notifys to the router when announcing
4809 the channel users to the router. Affected file silcd/server.c.
4810 If the router receiving channel founder CUMODE for a channel
4811 that already has channel founder it will send CUMODE notify
4812 to the sender to remove the channel founder rights from the
4813 announced client. Affected file silcd/packet_receive.c.
4815 * The CUMODE notify may now use Server ID as well as the entity
4816 who changes the mode. Updated protocool specs.
4818 * Updated INSTALL and README files.
4820 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * New web pages in the http://silc.pspt.fi. The pages was
4827 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4829 * Implemented the [DenyConnectin] config section in the server.
4830 Added silc_server_config_denied_conn to check whether incoming
4831 connection is denied. Affected file silcd/serverconfig.[ch].
4833 * Do not check the ports when checking the incoming configuration
4834 data if the port is 0, meaning any. Affected file is
4835 silcd/serverconfig.c.
4837 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4839 * Fixed buffer overflow in silc_string_compare in the file
4840 lib/silcutil/silcutil.c.
4842 * Fixed double free in silc_server_command_leave in the file
4845 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4847 * Fixed the version checking in the server. Affected file is
4850 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Fixed the configuration data fetching when accepting new
4853 connections in the server. Affected file silcd/server.c.
4855 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4857 * Added `sender_entry' argument to the function
4858 silc_server_packet_relay_to_channel so that we can check
4859 whether some destination actually belongs to the same route
4860 the sender belongs (ie, we must not resend the packet to the
4861 sender). Affected file silcd/packet_send.[ch].
4863 * Added `servername' field to the SilcClientEntry in the server
4864 to hold the name of the server where client is from. Affected
4865 file is silcd/idlist.h.
4867 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4869 * Moved the channel message encrypting in the router betwen
4870 router connections from silc_server_channel_message to the
4871 silc_server_packet_relay_to_channel since we want to check
4872 whether we have anybody channel before encrypting anything.
4873 Affected files silcd/packet_[receive/send].c.
4875 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4877 * Fixed the [AdminConnection] server config section to support
4878 multiple entries. Affected file silcd/serverconfig.c.
4880 * Added support into the server to check the validity of the
4881 incoming connection before executing any KE or authentication
4884 * The connection configuration is now saved to the KE and
4885 connection auth protocol contexts and not fetched anymore in
4886 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4888 * The local hosts listenning address and port is also resolved
4889 now when starting the server. We want to have the socket object
4890 to include the real address and port for the listener. Added
4891 new function silc_net_check_local_by_sock into the files
4892 lib/silcutil/silcnet.[ch].
4894 * Fixed a broadcast bug in server -> do not broadcast if we
4897 * Fixed a routing bug. Do not route broadcast packets ever.
4898 Broadcast packets must be processed always and not routed since
4899 they may be destined to some other host than yourself and thus
4900 would get routed without no good reason. Affected file is
4903 * Added function silc_server_config_is_primary_route to check
4904 whether primary router connection has been configured (a router
4905 configuration that we are initiating). If there is not, we
4906 will assume that there is only two routers in the SILC network
4907 and we will use the incoming router connection as our primary
4908 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4910 * Changed the order of the broadcasting. Broadcast _after_ the
4911 packet has been processed not before. Affected file is
4914 * Fixed a [ClientConnection] parsing bug. The port was never
4915 parsed correctly thus resulting to port 0. Affected file
4916 silcd/serverconfig.c.
4918 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4919 argument and did not set the broadcast packet flag. Affected
4920 file silcd/packet_send.c. Fixed same bug in the function
4921 silc_server_send_notify as well.
4923 * If we receive NEW_ID packet for our own ID in the server, ignore
4926 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4930 * Removed the nickname from the Private Message Payload.
4931 Updated the code and the protocol specs.
4933 * Updated protocol specs for submitting to the IETF.
4935 * Tweaked the Random Number Generator a bit. Affected file
4936 lib/silccrypt/silcrng.c. Exported a new function
4937 silc_rng_[global]_add_noise which can be used to add more
4940 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Do not parse packets with different timeout when protocol
4943 is active -> may cause problem with rekey. Affected file
4946 * When server receives signoff notify it must not create
4947 new channel key if the client is on any channels since the
4948 sender of the signoff notify will create it.
4950 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4952 * Added printing of error messages during SKE protocol from the
4953 failure packet sent by server during SKE. Affected file
4956 * Removed the client's failure_callback handling with timeout
4957 and handle it immediately when received.
4959 * The SKE library returned wrong type in SUCCESS and FAILURE
4960 packets. They must be 32 bit MSB not 16 bit MSB.
4962 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Ok, rewrote the logic of the re-key and now it seems to work.
4965 I tested it on high traffic with frequent re-keys without
4966 problems. Added hmac_receive (and renamed hmac to hmac_send)
4967 in SilcClientConnection in lib/silcclient/client.h and
4968 in SilcIDListData in silcd/idlist.h. Also, removed the
4969 SilcPacketParserContext's cipher and hmac fields as they are
4970 not needed anymore and actually caused some problems when
4971 the ciphers and hmac's changed underneath the packet parser.
4973 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4975 * If re-key protocol is active then process the incoming packets
4976 synchronously since we must assure that icoming packets encrypted
4977 with the old key is processed before the new keys is set to
4978 use. This is true other packets than for REKEY packets.
4979 Affected file silcd/server.c. The same was done to client library
4980 as well, affected file lib/silcclient/client.c.
4982 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4984 * Fixed bug in client and server to accept the force send if
4985 the packet is send from silc_[server/client]_packet_process
4986 function. Otherwise the packets are never delivered, oops.
4988 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4990 * Disable force sending of packets when REKEY protocol is active.
4991 We must assure that no packet is sent directly when rekey is
4992 performed. All packets must be sent through packet queue.
4993 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4994 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4995 function is silc_[server/client]_packet_send_real to check
4998 * Replaced the SIM paths from example config files to
4999 /usr/local/modules. Also, make install creates now
5000 /usr/local/silc/logs directory to hold all the SILC server
5003 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Made the configure.in.pre work on Solaris. Patch by salo.
5007 * Made all ciphers compatible with non-x86 machines. Defined
5008 CBC mode macros into lib/silccrypt/ciphers_def.h.
5010 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5012 * Fixed the make install.
5014 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5016 * When MAC computation fails the silc_packet_decrypt returned 0
5017 even though it was supposed to return -1. Fixed this. The
5018 affected file is lib/silccore/silcpacket.c.
5020 * Do not replace the config files in /etc/silc (in make install)
5021 if they already exist. Affected file ./Makefile.am.
5023 * Do not send re-key packets immediately but through packet queue.
5024 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
5026 * Changed silc_net_check_host_by_sock to return FALSE if the
5027 IP/DNS could not be resolved. Though, it returns the IP address
5028 now even if it could not resolve it (but returns also FALSE).
5029 Affected file lib/silcutil/silcnet.[ch].
5031 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5033 * Added silc_pkcs_decode_identifier to decode the public key's
5034 identifier. Affected file lib/silccrypt/silpkcs.[ch].
5035 Added also silc_pkcs_free_identifier. Added also new context
5036 SilcPublicKeyIdentifier.
5038 * Added -S option to the silc client. It is used to dump the
5039 contents of the specified public key file.
5041 * Changed the PKCS api to return the public key length when
5042 setting the public key.
5044 * Fixed a fatal bug in the public and private key file loading.
5045 Affected file lib/silccrypt/silcpkcs.c.
5047 * Execute the packet parsing for client with zero (0) timeout
5048 if the protocol is active. Affected file silcd/server.c.
5050 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5052 * Made the key generation options to the silcd program. Added
5053 -C option, equivalent to client's option.
5055 * Added new [ServerKeys] config section to the server. It
5056 configures the server's public and private key.
5058 * Defined generic Public Key Payload into the protocol
5059 specification to send specific type of public keys and
5062 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5063 public key or certificate.
5065 * Implemented the GETKEY command to the server and to the
5066 client library and on user interface.
5068 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5070 * Made preliminary `make install' work.
5072 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5074 * Added SilcServerRekey context into silcd/idlist.h.
5076 * Added the PFS support as defined in the specification to the
5077 SKE protocol. Affected files lib/silcske/*.c.
5079 * Added `ske_group' field to the SilcServerRekey context to hold
5080 the number of the SKE group that is used with PFS in re-key.
5081 Affected file silcd/idlist.h.
5083 * Added PFS re-key support to the server. Affected file is
5086 * Added silc_protocol_cancel to cancel execution of the next
5087 state of the protocol. Affected file is
5088 lib/silccore/silcprotocol.[ch].
5090 * Added the re-key support with and without PFS to the client
5091 library. Re-key is performed once in an hour, by default.
5093 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5094 Added silc_client_rekey_callback and silc_client_rekey_final.
5095 Affected files are lib/silcclient/protocol.[ch] and
5096 lib/silcclient/client.[ch].
5098 * Removed the `hmac_key' and `hmac_key_len' fields from the
5099 SilcClientConnection structure; not needed. Affected file is
5100 lib/silcclient/client.h.
5104 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Do not ask whether user wants to use the negotiated private key
5107 for private messages, just use it. Affected file is
5108 silc/local_command.c.
5110 * Added `send_enc_key' and `enc_key_len' fields to the
5111 SilcIDListData structure since they are needed in the re-key
5112 phase. Affected file is silcd/idlist.[ch].
5114 * Implemented the simple re-key protocol into the server.
5115 Affected files silcd/server.c and silcd/protocol.[ch]. The
5116 re-key will be performed once in an hour, by default.
5118 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5119 Added silc_server_rekey, silc_server_rekey_callback and
5120 silc_server_rekey_final.
5122 * Removed Tunneled flag from the protocol. Updated the code
5123 and the specifications.
5125 * Adde `pfs' field to the SilcIDListData to indicate whether
5126 the PFS is to be performed in the re-key. Affected file is
5129 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5132 int64 of at least the xintXX size. If void * is less that 4
5133 bytes uint32 * will be used. Defined bool as boolean.
5135 * Changed _ALL_ unsigned long and unsigned int to uint32,
5136 unsgined short to uint16 in the source tree.
5138 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5139 not handle clients that has entry->data.registered == FALSE.
5140 They are not in the network anymore. Affected file is
5143 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5145 * Implemented the sending of the SERVER_SIGNOFF notify in the
5146 server. Affected file is silcd/server.c.
5148 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5149 Added also silc_notify_payload_encode_args into the
5150 lib/silccore/silcnotify.[ch].
5152 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5153 Affected file silcd/packet_receive.c.
5155 * Implemented the SERVER_SIGNOFF notify handling in the client
5156 library. Affected file lib/silcclient/client_notify.c. Also,
5157 implemnted the printing of the SERVER_SIGNOFF info to the
5158 application. Affected file silc/client_ops.c.
5160 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5161 if the deleting was successful. Affected file silcd/idlist.[ch].
5163 * Added support for public key authentication in the connection
5164 authentication protocol in the client library. Affected file
5165 lib/silcclient/protocol.c.
5167 * Changed the server's silc_idlist_get_clients_by_* interface
5168 to support already allocated array so that new entries may be
5169 added to pre-allocated array. Affected file silcd/idlist.[ch].
5170 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5171 and command replies.
5173 * All command reply functions in the server now calls the
5174 pending command callback even if error occured. This way the
5175 error will be delivered to the client as well. Affected files
5176 silcd/command.c and silcd/command_reply.c.
5178 * Fixed INFO command to return local server's info if no server
5179 was provided. Affected file lib/silcclient/command.c.
5181 * Removed RESTART command for good. Updated the code and the
5184 * Rewrote parts of the task system. It is a bit simpler now.
5185 Removed unsued task priorities. The affected files are
5186 lib/silcutil/silctask.[ch].
5188 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5190 * Moved the USERS printing from the library to the application.
5191 Affected files lib/silcclient/command.c and silc/client_ops.c.
5193 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Added channel key re-key support. The re-key is perfomed
5198 only by the router and is done once in an hour. Added `rekey'
5199 field to the SilcChannelEntry in the server. Affected files
5200 silcd/server.c and silcd/idlist.h.
5202 * Added silc_task_unregister_by_context into the file
5203 lib/silcutil/silctask.[ch].
5205 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5207 * Added SILC_UMODE_GONE mode to indicate when the client is not
5208 present in the SILC network. Added also support to the local
5209 command AWAY that will set this mode. Added support of showing
5210 "xxx is gone" in WHOIS command. The USERS command shows the
5211 gone status as well.
5213 * Fixed setting server and router operator privileges in the
5214 server's UMODE command. Affected file silcd/command.c.
5216 * Merged the SKE KE1 and KE2 payloads into one payload. The
5217 new KE payload is equivalent to the old KE2 payload.
5219 Cleaned up the SKE Start Payload parsing. It now uses the
5220 simple buffer unformatting to do the parsing. A lot faster
5223 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5224 to the SKE that is used to indicate whether both of the SKE
5225 parties should perform authentication. By default only the
5226 responder performs authentication. By setting this flag also
5227 the initiator must do authentication. By default it is unset
5228 since in normal SKE case, client to server connection, only
5229 the responder should do authentication. When doing SKE between
5230 two clients both should perform authentication. Updated the
5231 code and the protocol specs.
5233 * A little fix to IDENTIFY command in the server. Search the
5234 client first by hash not nickname. Affected file is
5237 * Fixed the silc_client_close_connection to support closing
5238 the client to client connections wihtout deleting too much
5239 data. Affected file lib/silcclient/client.c.
5241 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5242 are received if protocol used to be active but is not anymore
5243 the application would crash due to NULL pointer dereference.
5244 Affected files silcd/server.c and lib/silcclient/client.c.
5246 * Added `hash' field to the SilcClientConnection to include
5247 the hash function negotiated in the SKE protocol.
5249 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5250 to set the channel founder authentication data. A client can
5251 claim the founder rights later by providing the authentication
5252 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5253 This way the channel founder can regain the channel founder
5254 privileges even it is left the channel. This works only on
5255 local server and the client must be connected to the same
5256 server to be able to regain the founder rights. Updated the
5257 protocol specs accordingly.
5259 Added support to the CMODE command in the client to set the
5260 founder auth data. Read the README to see how to set it.
5262 Added support to the CUMODE command to claim the founder
5263 rights. Read the README to see how to do it.
5265 Added support for the founder authentication to the Channel
5266 Entry in the server. Affected file silcd/idlist.h.
5268 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5269 server's CMODE command. Affected file silcd/command.c.
5271 * Added the following new functions into lib/silccore/silcauth.[ch]:
5272 silc_auth_get_method and silc_auth_get_data.
5274 * The server now saves the remote hosts public key to the
5275 SilcIDListData pointer. Affected file silcd/protocol.c.
5277 * The normal server now does not remove the channel entry from
5278 the cache if the founder authentication data is set. It used
5279 to remove it if the founder was the last one on the channel on
5280 the server and left the channel. The auth data is saved and
5281 if the channel is re-joined later the old entry is used with
5282 the old auth data. Affected files silcd/command_reply.c and
5285 * Removed the `pkcs' field from the SilcIDListData structure
5286 in the server; it is not used. Affected file silcd/idlist.h.
5288 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5290 * Fixed packet processing on slow links. Partial packets were
5291 never re-processed because the incoming data buffer was cleared
5292 by the application. Application must not directly clear the
5293 sock->inbuf, the packet processing routines handle it. Fixed
5294 this in client library and in server.
5296 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5298 * Fixed the WHOIS and IDENTIFY send reply function to really
5299 check whether to send list or just one entry. Affected file
5302 * Cleaned up the LEAVE command's channel key distribution. The
5303 affected file silcd/command.c.
5305 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5306 can enforce the channel mode as well. In that case the ID
5307 includes the ID of the server. The code now enforces the
5308 mode change if the router have different mode than the server.
5310 * The notify client operation with CMODE_CHANGE notify can now
5311 return NULL client_entry pointer if the CMODE was not changed
5312 by client. Application must check for this.
5314 * Added <Server ID> argument to INFO command to support server
5315 info fetching by Server ID.
5317 * Added silc_server_announce_get_channel_users to get assembled
5318 packets of channel users of the specified channel. Affected
5319 file silcd/server.[ch].
5321 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5322 was freed underneath the ID Cache.
5324 * Re-announce clients when the server received CHANNEL_CHANGE
5325 notify from the router. Affected file silcd/packet_send.c.
5327 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5330 crashed since it did not handle the fact that there is no cipher
5331 called "3" and didn't check the error condition. Now fixed.
5333 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5334 flag. It can be used to send message requests.
5336 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5338 * Implemented the RESTART command in the client.
5340 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5341 notice type messages. Added notice printing to the user
5344 * The channel keys are not re-generated if the channel's mode
5345 is PRIVKEY, ie private key on the channel exists. Affected
5346 files silcd/server.c and silcd/command.c.
5348 * Fixed a little bug in channel message delivery when channel
5349 private keys are set in the server. Affected file is
5350 silcd/packet_send.c.
5352 * Changed the setting on channel->on_channel = TRUE from the
5353 silc_client_save_channel_key to the JOIN command reply. The
5354 key payload is not received if the private channel key is set.
5355 Affected file lib/silcclient/command_reply.c and the
5356 lib/silcclient/client_channel.c.
5358 * When the CMODE_CHANGE notify is sent and the channel private
5359 key mode is removed the channel key must be re-generated in
5360 other cells as well. Added this support for the router in the
5361 silcd/packet_receive.c.
5363 * Added new local command NOTICE to send notice message on
5364 channel. Affected file silc/local_command.[ch].
5366 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5368 * Added new local command ME to the client. It is used to send
5369 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5370 some action. Affected file silc/local_command.[ch].
5372 * Changed channel_message and private_message client operations
5373 to deliver the message flags to the application. Added also
5374 the `flags' arguments to the silc_client_send_channel_message
5375 and silc_client_send_private_message functions. Affected file
5378 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5380 * Redefined the Private Message Payload to support private message
5381 keys and to support the new private message flags. Updated
5382 the protocol specs. Flags makes it possible to have for example
5383 CTCP style messages.
5385 * Added new type SilcPrivateMessagePayload and defined an API
5386 for it in the lib/silcclient/silcprivate.[ch].
5388 * Tested private message private keys successfully. Tested the
5389 private message key set, unset and list commands with the new
5392 * Redefined the Channel Message Payload to include the channel
5393 message flags (equal with private message flags) to support
5394 for example CTCP style messages.
5396 * Defined some of the message (for channel and private message)
5397 flags. Updated the protocol specs and added the flags to the
5398 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5400 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5402 * Added SilcKeyAgreementStatus type to the key agreement routines
5403 to indicate the current status and error if one occured.
5404 The status types are defined in the lib/silcclient/silcapi.h.
5406 * Added new local command KEY that is used to set and unset private
5407 keys for channels, set and unset private keys for private messages
5408 with remote clients and to send key agreement requests and
5409 negotiate the key agreement protocol with remote client. The
5410 key agreement is supported only to negotiate private message keys,
5411 it currently cannot be used to negotiate private keys for channels,
5412 as it is not convenient for that purpose.
5414 * Fixed a minor pending callback setting bug in the function
5415 silc_client_get_client_by_id_resolve, now the function works.
5416 Affected file lib/silcclient/idlist.c.
5418 * Added function silc_net_get_local_port to get local bound
5419 port by socket. Added to lib/silcutil/silcnet.[ch].
5421 * Added `sockets' and `sockets_count' fields to the SilcClient
5422 object. They hold the sockets of the listenning sockets in
5423 the client. Listenning sockets may be for example the key
5424 agreement server. Affected file lib/silcclient/client.[ch].
5425 Added functions the silc_client_add_socket and the
5426 silc_client_del_socket. They are exported to the application
5429 * Added ~./silc/clientkeys to support other client's public keys.
5431 * Renamed verify_server_key client operation to verify_public_key
5432 and added one argument to indicate the type of the connection
5433 (server, client etc.).
5435 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5437 * Added silc_server_connection_auth_request to handle the
5438 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5439 silcd/packet_receive.[ch].
5441 * Added silc_server_send_connection_auth_request into the
5442 silcd/packet_send.c to send the connection auth request packet.
5444 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5447 * Fixed the public key authentication in responder side in the
5448 server. The `auth_data' pointer includes the SilcPublicKey
5449 not the path to the public key. Affected file silcd/protocol.c.
5451 * Implemented the public key authentication in the initiator side
5452 in the server. Affected file silcd/protocol.c.
5454 * Removed the [RedirectClient] config section from the server
5455 configuration. Is not needed and I don't want to implement it.
5457 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5459 * Cleaned up the CMODE command in the server. It now works
5460 correctly and supports all the modes defined in the protocol.
5461 Affected file is silcd/command.c.
5463 * Added `hmac_name' field to the SilcChannelEntry in the server
5464 to hold the default HMAC of the channel. It can be set when
5465 creating the channel (with JOIN command). Affected files
5468 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5469 type to indicate the change of the current cipher and hmac
5470 on the channel. Client can safely ignore the <cipher> argument
5471 (if it chooses to do so) since the CHANNEL_KEY packet will
5472 force the channel key change anyway. The <hmac> argument is
5473 important since the client is responsible of setting the new
5474 HMAC and the hmac key into use.
5476 * Fixed the CMODE command in the client library as well.
5478 * Tested CMODE command in router environment successfully.
5480 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5482 * Show the version of the remote client (or server) when connecting
5483 to the server. It is logged to the log file. Affected file
5484 is silcd/protocol.c.
5486 * Fixed the KILLED notify handling in the client library. The
5487 client must be removed from all channels when receiving the
5490 Also, do not remove the client entry when giving the KILL
5491 command but when the KILLED notify is received.
5493 * Removed silc_idlist_find_client_by_nickname from the server.
5494 Not needed anymore. Affected files silcd/idlist.[ch].
5496 * Implemented the CHANNEL_CHANGE notify type handling to the
5497 server. Affected file silcd/server.c.
5501 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5503 * Added silc_server_send_notify_invite to send the INVITE
5504 notify between routers.
5506 * Implemented the INVITE command correctly to the server.
5508 * Implemented the INVITE notify type handling in the server.
5510 * Implemented the INVITE command to the client library and on the
5513 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5515 * Added function silc_server_get_client_resolve to find the
5516 client entry by ID from all ID lists and then resolve it
5517 (using WHOIS) if it cannot be found. Affected file is
5520 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5522 * Implemented the BAN command to the client library.
5524 * The JOIN command in the server now checks the invite list
5527 * Changed the silc_command_reply_payload_encode_va and the
5528 silc_command_payload_encode_va to support that if argument is
5529 NULL it ignores and checks the next argument. Affected file
5530 lib/silccore/silccommand.c.
5532 * Added silc_server_send_notify_ban to send the BAN notify
5533 type between routers.
5535 * Chaned the silc_notify_payload_encode to support that if
5536 argument is NULL it ignores and checks the next argument.
5537 Affected file lib/silccore/silcnotify.c.
5539 * Tested ban lists in router environment successfully.
5541 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5543 * Implemented BAN command to the server, in silcd/command.[ch].
5545 * Removed the BAN and INVITE_LIST modes from the CMODE command
5548 * Added function silc_string_match to regex match two strings.
5549 Affected files lib/silcutil/silcutil.[ch].
5551 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Redefined parts of the SilcChannelEntry in the server to support
5554 the new ban and invite lists.
5556 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5558 * Redefined the INVITE command. The same command can be used to
5559 invite individuals to the channel but also to manage the invite
5560 list of the channel (to add to and remove from the invite list).
5561 Updated the protocol specs.
5563 * Added new command SILC_COMMAND_BAN that can be used to manage
5564 the ban list of the channel. Updated the protocol specs.
5566 * Removed the channel modes: the SILC_CMODE_BAN and the
5567 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5568 in the CMODE command. The equivalent features are now available
5569 using INVITE and BAN commands. Updated the protocol specs.
5571 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5572 in the network about change in the current ban list. The notify
5573 type is not used by the client.
5575 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5576 support the invite lists.
5578 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5580 * Added new function silc_string_regexify that converts string
5581 including wildcard characters into regex string that can
5582 be used by the GNU regex library. Added into the file
5583 lib/silcutil/silcutil.[ch].
5585 Added silc_string_regex_combine to combine to regex strings
5586 into one so that they can be used as one regex string by
5587 the GNU regex library. Added into the file
5588 lib/silcutil/silcutil.[ch].
5590 Added silc_string_regex_match to match two strings. It returns
5591 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5593 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5595 * Imported GNU regex to the soruce tree into lib/contrib.
5596 Fixed some compiler warning from the regex.c.
5598 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5600 * Fixed MOTD command in the server to work in router environment.
5602 * Fixed the MOTD command in the client library to support
5603 the server argument in the command.
5605 * Added `nickname_len' argument to the silc_idlist_add_client
5606 in the server, as the `nickname' argument may be binary data
5609 * Added silc_idlist_get_channels to return all channels from
5612 * Implemented LIST command to the server. Affected file is
5615 * Implemented the LIST command to the client library and on the
5618 * Added [<user count>] argument to the LIST command reply.
5619 With private channels the user count is not shown.
5621 * Updated TODO and README.
5623 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5625 * The client entry's data.registered must be TRUE even with
5626 global client entry on global client list. The data.registered
5627 is used to check whether the client is anymore in the network,
5628 for example with WHOWAS command so it must be valid.
5630 * Fixed the WHOWAS command in the server. It now actually works
5631 in router environment. Added function into silcd/command_reply.c
5632 silc_server_command_reply_whowas_save.
5634 * Added silc_idlist_purge function to the silcd/idlist.c
5635 to periodically purge the ID Cache.
5637 * Fixed INFO command in the server. It works now in router
5638 environment. Added <server name> argument to the INFO command
5639 reply. Updated the protocol specs.
5641 * Fixed minor bug in silc_idcache_purge to not purge if the
5642 expire value is zero.
5644 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5645 they were buggy because of the WHOWAS information.
5647 * Fixed local command MSG to handle the async resolving of
5648 the remote client properly. It used to fail the first MSG.
5649 Affected file silc/local_command.c.
5651 * Added `data_len' field to SilcIDCache context.
5653 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5655 * Update TODO. Todo in commands in the server.
5657 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5660 used by routers as broadcast packet to inform other routers
5661 about the changed user mode.
5663 Implemented the notify handling in the server. Affected file is
5664 silcd/packet_receive.c. Added the function
5665 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5667 * Added new generic Channel Payload and deprecated the New Channel
5668 Payload. The New Channel Payload is now the generic Channel
5671 * Added new argument `mode' to the silc_server_send_new_channel
5672 as it is required in the Channel Payload now.
5674 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5675 and created a new and real SilChannelPayload to represent the
5676 new generic Channel Payload. Implemented the encode/decode
5677 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5679 * Added silc_server_get_client_channel_list to return the list
5680 of channels the client has joined for WHOIS command reply.
5681 Affected file silcd/server.[ch].
5683 * Implemented the channel list sending in the WHOIS command reply
5684 in server and in the client.
5686 Implemented the channel list displaying on the user interface
5687 as well. Affected file silc/client_ops.c.
5689 * Added silc_channel_payload_parse_list to parse list of Channel
5690 Payloads. It returns SilcDList list of SilcChannelPayloads.
5691 Client for example can use this function to parse the list of
5692 channels it receives in the WHOIS command reply. The caller
5693 must free the list by calling silc_channel_payload_list_free.
5694 Affected files lib/silccore/silcchannel.[ch].
5696 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5698 * Added one new argument <user mode> to the WHOIS command reply
5699 to return the mode of the user in SILC. Updated the protocol
5702 Implemented it to the server and client.
5704 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5706 * Fixed the mode printing on the user interface on joining.
5707 Affected file silc/client_ops.c.
5709 * Implemented the UMODE command and user modes in general to the
5710 client library and to the user interface.
5712 * Implemented the UMODE command to the server.
5714 * The server now sends UNKNOWN_COMMAND error status if client sends
5715 unknown command. Affected file silcd/command.c.
5717 * All server commands now handle the command identifier the right
5718 way when sending the command reply to the client. The client can
5719 use to identify the command replies with the identifier.
5721 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5723 * Added silc_server_get_client_route to resolve the route to
5724 the client indicated by the client ID. Affected file is
5727 * Added silc_server_relay_packet as general function to relay
5728 packet to arbitrary destination. This deprecates functions
5729 like _send_private_message_key, _relay_notify etc. Affected
5730 file is silcd/packet_send.[ch].
5732 Removed silc_server_send_key_agreement,
5733 silc_server_send_private_message_key and
5734 silc_server_packet_relay_notify functions from the file
5735 silcd/packet_send.[ch].
5739 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5740 server. Affected file silcd/packet_receive.[ch].
5742 * Implemented the KILL command to the client. Implemented the
5743 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5744 Affected files lib/silcclient/command[_reply].c and
5745 lib/silcclient/client_notify.c. Implemented the KILL notify
5746 printing in the user inteface.
5748 * Fixed a lot silc_parse_nick memory leaks from the client
5749 library in the file lib/silcclient/command.c.
5751 * Changed the silc_server_send_notify_on_channels's `sender'
5752 argument from SilcSocketConnection to SilcClientEntry to
5753 check the sender as entry and not as connection object and not
5754 to send to the client provided as argument. The affected file
5755 is silcd/packet_send.[ch].
5757 * The notify packets that are destined directly to the client used
5758 to not to be processed by the server. Now changed that and the
5759 server processes all notify packets. After relaying the packet
5760 to the client the notify packet is processed in the server.
5762 * The silc_server_free_client_data now checks whether there is
5763 pending outgoing traffic for the client and purges the data to
5764 the network before removing the client entry.
5766 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5768 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5769 an client is killed from the SILC Network. Updated the protocol
5772 Added new function silc_server_send_notify_killed to the
5773 silcd/packet_send.[ch].
5775 * Added function silc_server_packet_relay_notify to relay notify
5776 packets that are destined directly to a client. In this case
5777 the server does not process the notify packets but merely relays
5778 it to the client. Affected file silcd/packet_send.[ch].
5780 Added also silc_server_packet_process_relay_notify to check
5781 whereto relay the notify. Affected file is
5782 silcd/packet_receive.[ch].
5784 * Implemented the KILL command to the server.
5788 * Added the backup schema desgined last fall to the protocol
5789 specs for everyone to see. The specification is in the
5790 *-spec-xx.txt draft and the packet type definitions for the
5791 backup routers is in *-pp-xx.txt draft. Thusly, added also
5792 new packet type SILC_PACKET_CELL_ROUTERS.
5794 * A big security problem in the implementation discovered. The
5795 signoff of an client did not cause new channel key generation
5796 which it of course should've done. The channel keys must be
5797 always re-generated when client leaves (or signoffs) the channel.
5798 The silc_server_remove_from_channels funtion now handles
5799 the channel key re-generation.
5801 * Added `sender' argument to the silc_server_send_notify_on_channels
5802 to not to send the client provided as argument. Affected file
5803 silcd/packet_send.[ch].
5805 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5807 * Implemented OPER and SILCOPER commands into the server and
5810 * Added silc_auth_verify and silc_auth_verify_data to verify
5811 the authentication directly from the authentication payload.
5812 It supports verifying both passphrase and public key based
5813 authentication. Affected file lib/silccore/silcauth.[ch].
5815 * Added `hash' field to the SilcIDListData structure. It is the
5816 hash negotiated in the SKE protocol. Affected file is
5819 * Slight redesigning of the SilcAuthPayload handling routines.
5820 Do not send SilcPKCS but SilcPublicKey as argument.
5822 * Implemented the public key authentication support to the
5823 serverconfig. The public key is loaded from the provided path
5824 and saved as authentication data to void * pointer. Thus,
5825 changed the unsigned char *auth_data to void *auth_data;
5827 * Fixed SHUTDOWN command to send the reply before the server
5828 is shutdown. :) Affected file silcd/command.c.
5830 * Fixed fatal bug in CONNECT command. The hostname was invalid
5831 memory and server crashed. Affected file silcd/command.c.
5833 * Fixed fatal bug in CLOSE command. The server_entry became
5834 invalid but was referenced later in the command. Affected file
5837 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5839 * Fixed fatal bug in failure packet handling. Server ignored
5840 the failure and thus crashed when it came.
5844 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5846 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5847 that the command may be executed only once in (about) 2 seconds.
5848 The old SILC_CF_LAG flag is same but allows command bursts up
5849 to five before limiting.
5851 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5852 server code. Various commands now includes the CF_LAG_STRICT
5853 flag to disallow any kind of miss-use of the command.
5855 * Fixed the silc_buffer_unformat to not to allocate any data
5856 if the length of the data is zero. It used to allocate the
5857 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5859 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5861 * Changed the format of AdminConnection configuration section
5862 in the server. Added username of the admin to the format.
5863 Affected files silcd/serverconfig.[ch].
5865 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5866 to return admin configuration data by host, username and/or
5869 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5871 * Implemented WHOWAS command to the server. Added the functions:
5873 silc_server_command_whowas_parse,
5874 silc_server_command_whowas_send_reply,
5875 silc_server_command_whowas_from_client and
5876 silc_server_command_whowas_from_server
5878 * Added <Client ID> argument to the WHOWAS command reply. Updated
5879 the protocol specs accordingly.
5881 * Implemented WHOWAS command and command_reply to the client
5884 Implemented the WHOWAS printing on the user interface.
5886 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5888 * Added new argument to the WHOWAS command reply, the real name.
5889 It is an optional argument. Updated the protocol specs.
5891 * Added SilcIDCacheDestructor callback that is registered when
5892 the SilcIDCache is allocated. The callback is called when
5893 an cache entry in the ID Cache expires, or is purged from the
5894 cache. Added into lib/silccore/idcache.[ch].
5896 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5897 to destruct the client entries when the cache entry expires.
5898 Other ID Cache's in server and in the client library ignores
5901 * If the ID Cache entry's `expire' field is zero then the entry
5902 never expires. Added boolean `expire' argument to the
5903 silc_idcache_add function in the lib/silccore/idcache.[ch].
5904 If it is TRUE the default expiry value is used.
5906 * Added silc_server_free_client_data_timeout that is registered
5907 when client disconnects. By default for 5 minutes we preserve
5908 the client entry for history - for WHOWAS command.
5910 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5912 * Added support to the server to enforce that commands are not
5913 executed more than once in 2 seconds. If server receives
5914 commands from client more frequently, timeout is registered
5915 to process the commands. Affected file silcd/command.c.
5916 Added new function silc_server_command_process_timeout.
5918 * Changed NICK_NOTIFY handling in client library to check that
5919 if the client's nickname was changed, so there is no need to
5920 resolve anything from the server.
5922 * Removed error printing from the WHOIS and IDENTIFY commands.
5923 If error occurs then it is ignored silently in the client library.
5924 The application, however, may map the received error to
5925 human readable error string. The application currently maps
5926 the NO_SUCH_NICKNAME error to string.
5928 * Made the command status message public to the application. Moved
5929 them from lib/silcclient/command_reply.c to
5930 lib/silcclient/command_reply.h. The application can map the
5931 received command status to the string with the
5932 silc_client_command_status_message function.
5934 * Added check to the server to check that client's ID is same
5935 as the Source ID in the packet the client sent. They must
5938 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5940 * Added dist-bzip hook to the Makefile.am to make bzip2
5941 compressed distributions.
5943 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5945 * Server now enforces the maximum length for the nickname and
5946 the channel as protocol specification dictates. 128 bytes for
5947 nickname and 256 bytes for channel name.
5949 * Moved the WHOIS printing to the application. The client libary
5950 does not print out the WHOIS information anymore, the application
5951 must do it. Renamed silc_client_command_reply_whois_print to
5952 the silc_client_command_reply_whois_save.
5954 The client's idle time is also sent to the application now, and
5955 the idle is shown on screen.
5957 * Added silc_client_command_reply_identify_save to save the
5958 received IDENTIFY entries.
5960 * Do not check for channel private keys in message sending and
5961 reception if the channel does not have the PRIVKEY mode set.
5962 Affected file lib/silclient/client_channel.c.
5964 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5966 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5967 just surfaced after chaning the JOIN procedure.
5969 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5971 * Added silc_client_get_clients_by_list to get client entries
5972 from Client ID list, that is returned for example by JOIN
5973 and USERS command replies. The application should use this
5974 function for example when JOIN command reply is received to
5975 resolve the clients already on the channel (library does not
5976 do that anymore as USERS command reply is not used in the JOIN
5977 procedure anymore). Affected files lib/silcclient/silcapi.h and
5978 lib/silcclient/idlist.c.
5980 * JOIN command reply and USERS command reply returns now SilcBuffer
5981 pointers instead of unsigned char pointers when returning
5982 the client list and mode list.
5984 * Added <Client ID> argument to the JOIN command reply, mainly
5985 for the server to identify for which client the command was
5986 originally sent. Updated protocol specs accordingly.
5988 * Added SilcDlist private_key pointer to the SilcChannelEntry
5989 in the client to support the channel private keys. Affected
5990 file is lib/silcclient/idlist.h.
5992 * Added SilcChannelPrivateKey argument to the function
5993 silc_client_send_channel_message so that application can choose
5994 to use specific private ke if it wants to. If it is not provided,
5995 the normal channel key is used, unless private keys are set.
5996 In this case the first (key that was added first) is used
5997 as the encryption key.
5999 * Implemented the support for channel private key handling.
6000 Implemented the following functions:
6002 silc_client_add_channel_private_key,
6003 silc_client_del_channel_private_keys,
6004 silc_client_del_channel_private_key,
6005 silc_client_list_channel_private_keys and
6006 silc_client_free_channel_private_keys
6008 Affected file lib/silcclient/client_channel.c.
6010 * Added the support for the private keys in the channel message
6011 sending and encryption and in the message reception and
6012 decryption. Affected funtions are
6013 silc_client_send_channel_message and silc_client_channel_message.
6015 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6017 * Added SKE's key verify callback to the client library's
6018 KE protocol context. Affected files lib/silcclient/protocol.[ch].
6020 * Removed the statement that server (or router) must send USERS
6021 command reply when joining to the channel so that the client
6022 knows who are on the channel. Instead, the client list and
6023 client's mode list is now sent in the JOIN command reply to the
6024 client who joined channel. This is better solution.
6026 * Added function silc_server_get_users_on_channel and function
6027 silc_server_save_users_on_channel to the silcd/server.[ch].
6029 * Removed function silc_server_command_send_users from the
6032 * Do not show topic on the client library anymore. The topic is
6033 sent in the command reply notify to the application and the
6034 application must show the topic now.
6036 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6038 * Added client searching by nickname hash into the IDENTIFY and
6039 WHOIS commands in the server as they were clearly missing from
6040 them. Affected file is silcd/command.c.
6042 * Fixed a bug in private message receiving in the client library.
6043 The remote ID was freed and it wasn't supposed, now it is
6046 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6048 * Minor fix to the channel payload; allocate the data area, as it
6049 needs to be of specific length.
6051 * If the key agreement port is zero then the operating
6052 system will define the bound port. Affected files are
6053 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6055 * Added new function silc_channel_payload_decrypt into the file
6056 lib/silccore/silcchannel.[ch].
6058 * Moved the channel message etc, check from silc_packet_decrypt
6059 to applications. The library calls now a generic
6060 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6061 when the packet is either normal or special. This was done to
6062 allow more wide range of checking that was not allowed when
6063 the code was in library. Now applications can do virtually any
6064 checks to the packet and return to the library the decision how
6065 the packet should be processed. Affected files are
6066 lib/silccore/silcpacket.[ch].
6068 Added silc_server_packet_decrypt_check to the server and
6069 silc_client_packet_decrypt_check to the client library.
6071 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6072 to send with specified source and destination information.
6074 * Channel message delivery between routers was broken after the
6075 channel key distribution was fixed earlier. The channel key
6076 was used be to distributed to other routers as well which is not
6077 allowed by the protocol. Now this is fixed and channel keys
6078 really are cell specific and the channel message delivery between
6079 routers comply with the protocol specification.
6081 * Fixed various commands in server to check also the global list
6082 for the channel entry and not just the local list. The affected
6083 file silcd/command.c.
6085 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6087 * Added assert()s to buffer formatting and unformatting routines
6088 to assert (if --enable-debug) when error occurs. Affected
6089 file: lib/silcutil/silcbuffmt.c.
6091 * Changed to auto-reconnect to check whether the remote host is
6092 router and register the re-connect timeout if it is. It used
6093 to check that whether we are normal server, but router must do
6094 auto-reconnect with another router as well. Affected file
6097 * Removed the [<key len>] option from CMODE command as the cipher
6098 name decides the key length, nowadays. See the defined ciphers
6099 from the protocol specification.
6101 * Added [<hmac>] option to the CMODE command to define the HMAC
6102 for the channel. Added SILC_CMODE_HMAC channel mode.
6104 * Added [<hmac>] option for the JOIN command so that user can
6105 select which HMAC is used to compute the MACs of the channel
6108 * Added Hmac field to the Channel Message Payload. The integrity
6109 of plaintext channel messages are now protected by computing
6110 MAC of the message and attaching the MAC to the payload. The
6111 MAC is encrypted. Now, it is clear that this causes some
6112 overhead to the size of the packet but rationale for this is that
6113 now the receiver can verify whether the channel message decrypted
6114 correctly and also when private keys are set for the channel the
6115 receiver can decrypt the packet with several keys and check from
6116 the MAC which key decrypted the message correctly.
6118 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6119 lib/silccrypt/silccipher.[ch].
6121 * Added silc_hash_len to return the digest length into the
6122 lib/silcrypt/silchash.[ch].
6124 * Rewrote parts of Silc Channel Payload interface in the
6125 lib/silccore/silcchannel.[ch]. The encode function now also
6126 encrypts the packet and parse function decrypts it.
6128 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6130 * Fixed a minor formatting bug in the SKE's key material processing.
6131 It actually might have processed the keys wrong way resulting
6134 * Redefined the mandatory HMAC algorithms and added new algorithms.
6135 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6136 and hmac-md5 truncated to 96 bits. The mandatory is now
6137 hmac-sha1-96. Rest are optional (including the one that used
6138 to be mandatory). Rationale for this is that the truncated HMAC
6139 length is sufficient from security point of view and can actually
6140 make the attack against the HMAC harder. Also, the truncated
6141 HMAC causes less overhead to the packets. See the RFC2104 for
6144 * Added new [hmac] configuration section. The SKE used to use
6145 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6146 is of course wrong. The official names that must be proposed in
6147 the SKE are the ones defined in the protocol specification
6148 (hmac-sha1-96 for example). The user can configure any hmac
6149 using any hash function configured in the [hash] section. At
6150 least, the mandatory must be configured.
6152 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6154 * Added HMAC list to the SKE proposal list. It has now both
6155 hash algorithm list and HMAC list. This makes the protocol
6156 incompatible with previous versions. The SKE now seems to work
6157 the way it is supposed to work, for the first time actually.
6159 * Defined plain Hash algorithms to the protocol specification.
6162 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6164 * Implemented support for key agreement packets into the server.
6165 Added functions silc_server_key_agreement and
6166 silc_server_send_key_agreement. Other than these functions,
6167 server has nothing to do with this packet.
6169 * Added support for private message key packets into the server.
6170 Added functions silc_server_private_message_key and
6171 silc_server_send_private_message_key.
6175 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6176 called in the protocol's final callback instead in the END
6177 protocol state. This makes a little more sense and in the same
6178 time in client we can use the same protocol routines for normal
6179 key exchange and to key agreement packet handling as well.
6181 * Added to both client's and server's KE protocol context the
6182 SilcSKEKeyMaterial pointer to save the key material. We will
6183 bring the key material to the protocol's final callback by doing
6184 this. The final callback must free the key material.
6186 * Added SKE's packet_send callback into client's KE protocol
6187 context so that the caller can choose what packet sending function
6188 is used. This way we can use different packet sending when
6189 doing normal SKE when doing key agreement packet handling (in
6190 the key agreement packet handling we do not want to encrypt
6193 * Implemented the responder side of the key agreement routines
6194 in the client. The client can now bind to specified port and
6195 accept incoming key negotiation. The key material is passed
6196 to the application after the protocol is over.
6198 * Implemented the processing of incoming Key Agreement packet
6199 in the client. Added function silc_client_key_agreement to
6202 * Implemented the intiator side of the key agreement routines
6203 in the client. The client can now initiate key agreement with
6204 another remote client. The key material is passed to the
6205 application after the protocol is over.
6207 * Created client_keyagr.c to include all the key agreement
6210 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6211 SILC_TASK_CALLBACK except that it is not static.
6213 * Created client_notify.c and moved the Notify packet handling
6214 from the client.[ch] into that file.
6216 * Created client_prvmsg.c and moved all private message and
6217 private message key routines from the client.[ch] into that file.
6219 * Create client_channel.c and moved all channel message and
6220 channel private key routines from the client.[ch] into that file.
6222 * Changed silc_client_get_client_by_id_resolve to resolve with
6223 WHOIS command instead of IDENTIFY command, in the file
6224 lib/silclient/idlist.c.
6226 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6228 * Implemented the SKE's responder side to the Client library.
6230 * When FAILURE is received to the protocol do not trust it
6231 blindly. Register a timeout to wait whether the remote closes
6232 the connection as it should do it, only after that process the
6233 actual failure. This was changed to both client and server.
6235 * Added client_internal.h to include some of the structures
6236 there instead of client.h in lib/silcclient/.
6238 * Added function silc_task_unregister_by_callback to unregister
6239 timeouts by the callback function.
6241 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6243 * Some "Incomplete WHOIS info" errors has been appearing on the
6244 log files. Took away the entry->userinfo check from WHOIS
6245 reply sending. The entry->userinfo is now " " if client did not
6246 provide one. I thought this was fixed earlier but something
6247 is wrong still. Let's see if the error still appears.
6249 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6251 * Fixed a minor bug in the login when the channel key is
6252 re-generated in the server. It used to generate the key in
6253 wrong order and thus caused problems in the channel traffic.
6255 * Fixed a minor bug in channel key distsribution after
6256 KICK command. The key was not sent to the router even though
6259 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6261 * Added silc_ske_process_key_material_data as generic routine
6262 to process any key material as the SILC protocol dictates. The
6263 function is used by the actual SKE library but can be used by
6264 applications as well. This relates to the private message keys
6265 and the channel private keys since they must be processed the
6266 same way the normal SILC session keys. The protocol dictates
6267 this. Affected files: lib/silcske/silcske.[ch].
6269 Added also silc_ske_free_key_material to free the
6270 SilcSKEKeyMaterial structure.
6272 * Defined silc_cipher_set_key function to set the key for
6273 cipher without using the object's method function. The affected
6274 files: lib/silccrypt/silccipher.[ch].
6276 * Implemented silc silc_client_add_private_message_key,
6277 silc_client_add_private_message_key_ske,
6278 silc_client_del_private_message_key,
6279 silc_client_list_private_message_keys and
6280 silc_client_free_private_message_keys functions in the
6283 Added functions silc_client_send_private_message_key to send
6284 the Private Message Key payload and silc_client_private_message_key
6285 to handle incoming Private Message Key payload.
6287 * Added Cipher field to the Private Message Key payload to set
6288 the cipher to be used. If ignored, the default cipher defined
6289 in the SILC protocol (aes-256-cbc) is used.
6291 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6293 * Removed lib/silcclient/ops.h file.
6295 Redefined parts of the SILC Client Library API. Created new
6296 file silcapi.h that deprecates the ops.h file and defines the
6297 published Client Library API. Defined also private message key
6298 API and channel private key API into the file.
6300 This is the file that the application must include from the
6301 SILC Client Library. Other files need not be included by
6302 the application anymore.
6304 * Added new key_agreement client operation callback and also
6305 defined the Key Agreement library API for the application.
6307 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6309 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6310 is used by clients to request key negotiation between another
6311 client in the SILC network. If the negotiation is started it
6312 is performed using the SKE protocol. The result of the
6313 negotiation, the secret key material, can be used for example
6314 as private message key.
6316 Implemented the Key Agreement payload into the files
6317 lib/silccore/silauth.[ch].
6319 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6321 * Redefined ciphers for the SILC protocol. Added some new ciphers
6322 and defined the key lengths for the algorithms. Changed the
6323 code accordingly. The default key length is now 256 bits.
6325 * Fixed SKE key distribution function silc_ske_process_key_material
6326 when the key length is more than 128 bits. The default key
6327 length in SILC is now 256 bits.
6329 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6330 to indicate unsupported algorithm.
6332 * Renamed rijndael.c to aes.c and all functions as well.
6334 * Fixed a long standing channel key setting bug in client library.
6335 Weird that it has never surfaced before.
6337 * Fixed bug in channel deletion. If the entire channel is removed
6338 then it must also delete the references of the channel entry
6339 from the client's channel list as the client's channel entry and
6340 the channel's client entry share same memory.
6342 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6344 * Implemented CONNECT and SHUTDOWN commands in the client.
6346 * Implemented CLOSE command to the client.
6348 * Added the function silc_idlist_find_server_by_name into the
6349 files silcd/idlist.[ch].
6351 Added the function silc_idlist_find_server_by_conn into the
6352 files silcd/idlist.[ch].
6354 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6356 * DIE command was renamed to SHUTDOWN. Updated the both code
6359 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6360 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6362 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6365 * Added function silc_server_create_connection function to create
6366 connection to remote router. My server implementation actually
6367 does not allow router to connect to normal server (it expects
6368 that normal server always initiates the connection to the router)
6369 so the CONNECT command is only good for connecting to another
6372 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6374 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6375 or some other client was kicked from the channel.
6377 Implemented the handling of the notify type to both client
6380 Implemented silc_server_send_notify_kicked to send the KICKED
6381 notify. It is used to send it to the server's primary router.
6383 * Implemented the KICK command into server and client.
6385 * Added `query' argument to the silc_idlist_get_client function
6386 to indicate whether to query the client from server or not if
6389 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6390 to indicate that the client is not channel founder.
6394 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6396 * Removed the rng context from SilcPacketContext structure and
6397 changed that the packet routine uses the Global RNG API.
6399 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6401 * Added support for quit message that client can "leave" on the
6402 channel when it quits the SILC. It is ditributed inside the
6403 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6405 Added silc_server_free_client_data that will take the
6406 signoff message as argument.
6408 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6410 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6412 * Updated parts of the protocol specification to keep it up
6415 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6417 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6418 payloads in one packet.
6420 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6421 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6422 use now the new List flag.
6424 * Also deprecated the following packet types: REPLACE_ID,
6425 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6427 * Added list support for Notify packet in server.
6429 * Added silc_server_send_notify_channel_change to send the
6430 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6431 the silc_server_send_replace_id.
6433 * Added silc_server_send_notify_nick_change to send the
6434 NICK_CHANGE notify type. Deprecates the function
6435 silc_server_send_replace_id.
6437 * Added silc_server_send_notify_join to send the JOIN notify type.
6438 Deprecates the function silc_server_send_new_channel_user.
6440 * Added silc_server_send_notify_leave to send LEAVE notify type.
6441 Deprecates the function silc_server_send_remove_channel_user.
6443 * Added silc_server_send_notify_cmode and
6444 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6445 types. Deprecates the silc_server_send_set_mode function.
6447 * Added SERVER_SIGNOFF notify type to indicate that server has
6448 quit. This means that all clients on the channel from that
6449 server will drop. This can be also used when netsplit happens.
6451 Deprecated REMOVE_ID packet type since it is not needed anymore
6454 Added silc_server_send_notify_server_signoff to send the
6455 SERVER_SIGNOFF notify type. Deprecates the function
6456 silc_server_send_remove_id.
6458 Added also silc_server_send_notify_signoff to send the
6459 SIGNOFF notify type.
6461 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6462 SILC protocol from this day on. Changed the protocol
6463 specification as well.
6465 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6466 notify type. It is used between routers to notify about
6467 topic changes on a channel.
6469 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6472 * Partly updated the protocol specification to comply with the
6473 changes now made. It is still though a bit outdated.
6475 * The JOIN notify type now takes one extra argument <Channel ID>.
6476 The packet used to be destined to the channel but now the
6477 JOIN type may be sent as list thus it is impossible to
6478 destine it to any specific channel. By adding this argument
6479 it is again possible.
6481 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6483 * Added CREDITS file. The CHANGES and CREDITS file will appear
6484 in the distribution as well.
6486 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6489 types in the server's silcd/packet_receive.c.
6491 * Implemented CMODE and CUMODE to work in router environment.
6493 * Fixed minor encoding and decoding buglet from the
6494 lib/silccore/silcmode.c.
6496 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6499 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6501 * Changed all SilcConfigServer* and silc_config_server* to
6502 SilcServerConfig* and silc_server_config*, respectively.
6505 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6507 * Associated the ID (client or server ID) to the Authentication
6508 Payload to avoid any possibility of forging. Updated the
6509 protocol specification and the code accordingly.
6511 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6513 * The RSA key length is now save to the RsaKey context in the
6514 key generation process in lib/silccrypt/rsa.c. The key length
6515 is now used to figure out the maximum size of the block allowed
6516 to be encrypted/signed.
6518 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6519 is equivalent to the silc_mp_mp2bin but does not allocate any
6522 * Changed silc_mp_mp2bin API to take length argument. If it is
6523 non-zero then the buffer is allocated that large. If zero, then
6524 the size is approximated using silc_mp_sizeinbase, which however
6527 * Created Global RNG API which is global RNG that application can
6528 initialize. After initializing, any routine anywhere in the
6529 code (including library) can use RNG without allocating a new
6530 RNG object. This was done to allow this sort of use of the
6531 RNG in code that has no chance to allocate RNG object. All
6532 applications currently allocate this and many routines in the
6533 library use this. Affected file lib/silccrypt/silcrng.[ch].
6535 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6536 it to use the Global RNG API.
6538 * Defined Authentication Payload into protocol specification that
6539 is used during SILC session to authenticate entities. It is
6540 used for example by client to authenticate itself to the server
6541 to obtain server operator privileges.
6543 Implemented this payload into the lib/silccore/silcauth.[ch].
6544 Implemented also routines for public key based authentication
6545 as the new protocol specification dictates.
6547 Moved definitions of different authentication methods from
6548 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6550 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6551 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6552 silc_pkcs_verify_with_hash functions into the file
6553 lib/silccrypt/silcpkcs.[ch].
6555 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6557 * The client entry's userinfo pointer must be always valid.
6558 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6559 will fail since it requires the userinfo. Now, the userinfo
6560 is allocated as "" if actual userinfo does not exist. Actually,
6561 it must exist and it is totally Ok to drop client connections
6562 that does not announce the userinfo. However, we will make
6563 this workaround for now.
6565 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6566 to return the remote port by socket.
6568 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6570 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6571 SILC_SERVER_PENDING_EXEC and added an new macro
6572 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6573 data or when error occurs while processing the pending command.
6575 Added new argument `destructor' into silc_server_command_pending
6576 and to the SilcServerCommandPending object. This destructor is
6577 now called after calling the pending callback or if error occurs
6578 immediately. If error occurs the actual pending callback won't
6579 be called at all - only the destructor. The destructor may be
6580 NULL if destructor is not needed.
6582 All this applies for client library code as well. Similar
6583 changes were made there as well for the pending commands.
6585 In the client, the application must now allocate the
6586 SilcClientCommandContext with the silc_client_command_alloc
6589 * Added reference counter to the SilcServerCommandContext. Added
6590 function silc_server_command_alloc and silc_server_command_dup
6593 Same type of functions added to the client library for the same
6596 * Removed the cmd_ident from IDListData away since it is now
6597 global for all connections. It is the command identifier used
6598 in command sending and with pending commands. The affected file
6601 * Added reference counter to the SilcSocketConnection objecet to
6602 indicate the usage count of the object. The object won't be
6603 freed untill the reference counter hits zero. Currently only
6604 server uses this, and client ignores it. The client must be
6605 set to use this too later. The affected files are
6606 lib/silccore/silcsockconn.[ch]. Added also the function
6607 silc_socket_dup to increase the reference counter.
6609 This was mainly added because it is possible that the socket
6610 is removed underneath of pending command or other async
6611 operation. Now it won't be free'd and proper DISCONNECTING
6612 flags, etc. can be set to avoid sending data to connection that
6613 is not valid anymore.
6615 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6616 the connection. After that it sets SILC_SET_DISCONNECTED.
6617 It is, however, possible that the socket data is not still freed.
6618 The silc_server_packet_process now checks that data is not
6619 read or written to connection that is DISCONNECTED. The socket
6620 get's freed when the reference counter hits zero.
6622 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6624 * Changed the client operation API: channel_message operation's
6625 `sender' is now the client entry of the sender, not the nickname
6626 and the `channel' is the channel entry, not the channel name.
6628 In the private_message operation the `sender' is now also the
6629 client entry of the sender not the nickname.
6631 Affected file is lib/silcclient/ops.h and all applications
6632 using the client operations.
6634 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6636 * Moved the calling of ops->connect() from connect_to_server_final
6637 into receive_new_id functin since that is the point when the
6638 client is actually allowed to send traffic to network. The
6639 affected file is lib/silcclient/client.c.
6641 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6643 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6644 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6645 (if needs broadcasting) instead of broadcasting the packets one
6646 by one which would make a burst in the network traffic.
6648 * Added `broadcast' argument to the functions in silcd/server.[ch]
6649 silc_server_create_new_channel[_with_id] to indicate whether
6650 to send New Channel packet to primary router.
6652 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6654 * Added new function into the silcd/server.[ch] files:
6655 silc_server_create_new_channel_with_id to create new channel with
6656 already existing Channel ID.
6658 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6659 lib/silccore/silcpacket.h. This packet is used t send list of
6660 Set Mode payloads inside one packet. Server uses this to set
6661 the modes for the channels and clients on those channels, that it
6662 announced to the router when it connected to it. The protocol
6663 specification has been updated accordingly.
6665 * The silc_server_new_channel did not handle the packet coming
6666 from normal server as it normally does not send that. However,
6667 when it announces its channels it does send it. Implemented
6668 the support for that.
6670 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6671 into the file lib/silccore/id.h.
6673 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6675 * Fixed memory leaks in the functions silc_idlist_del_client,
6676 silc_idlist_del_channel and silc_idlist_del_server in the file
6677 silcd/idlist.c. All of those leaked like a sieve.
6679 * Fixed some small memory leaks in the client's function
6680 silc_client_notify_by_server.
6682 * Added functions into silcd/server.c: silc_server_announce_clients,
6683 silc_server_announce_channels and silc_server_announce_server.
6684 These functions are used by normal and router server to announce
6685 to its primary router about clients, channels and servers (when
6686 router) that we own. This is done after we've connected to the
6689 These functions effectively implements the following packet types:
6690 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6691 and SILC_PACKET_NEW_ID_LIST.
6693 * Added new functions into the silcd/packet_receive.[ch]:
6694 silc_server_new_id_list, silc_server_new_channel_list and
6695 silc_server_new_channel_user_list to handle the incoming
6696 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6698 * Added support of changing Channel ID in the function
6699 silc_server_replace_id. If the server that announces a channel
6700 to the router already exists in the router (with same name but
6701 with different Channel ID), router is responsible to send
6702 Replace ID packet to the server and force the server to change
6703 the Channel ID to the one router has.
6705 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6706 client that the Channel ID has been changed by the router. The
6707 normal server sends this to the client. Client must start using
6708 the new Channel ID as the channel's ID.
6710 Implemented handling of this new type into lib/silcclient/client.c
6711 into the function silc_client_notify_by_server.
6713 * Added new function silc_idlist_replace_channel_id into the files
6714 silcd/idlist.[ch] to replace the Channel ID.
6716 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6718 * Call silc_server_command_identify_check always when processing
6719 the IDENTIFY command in silcd/command.c
6721 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6723 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6724 send keepalive packets. The packet can be sent by clients,
6725 servers and routers.
6727 Added function silc_socket_set_heartbeat into the file
6728 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6729 If not set, the heartbeat is not performed. The actual
6730 heartbeat is implemented in the low level socket connection
6731 library. However, application is responsible of actually
6734 Added silc_server_send_heartbeat to send the actual heartbeat
6735 packet into silcd/packet_send.[ch]. Server now performs
6736 keepalive with all connections.
6738 * Added silc_task_get_first function into lib/silcutil/silctask.c
6739 to return the timeout task with shortest timeout. There was a bug
6740 in task unregistration that caused problems. TODO has been
6741 updated to include that task system must be rewritten.
6743 * The client library will now resolve the client information when
6744 receiving JOIN notify from server for client that we know but
6745 have incomplete information.
6747 * Rewrote parts of silc_server_remove_from_channels and
6748 silc_server_remove_from_one_channel as they did not remove the
6749 channel in some circumstances even though they should've.
6751 * Encryption problem encountered in server:
6753 The LEAVE command used to send the Channel Key packet to the
6754 router immediately after generating it. However, the code
6755 had earlier sent Remove Channel user packet but not immediately,
6756 ie. it was put to queue. The order of packets in the router
6757 was that Channel Key packet was first and Remove Channel User
6758 packet was second, even though they were encrypted in the
6759 reverse order. For this reason, MAC check failed. Now, this
6760 is fixed by not sending the Channel Key packet immediately but
6761 putting it to queue. However, this is more fundamental problem:
6762 packets that are in queue should actually not be encrypted
6763 because packets that are sent immediately gets encrypted
6764 actually with wrong IV (and thus MAC check fails). So, packets
6765 that are in queue should be encrypted when they are sent to
6766 the wire and not when they put to the queue.
6768 However, the problem is that the current system has not been
6769 designed to work that way. Instead, the packet is encrypted
6770 as soon as possible and left to the queue. The queue is then
6771 just purged into wire. There won't be any fixes for this
6772 any time soon. So, the current semantic for packet sending
6775 o If you send packet to remote host and do not force the send
6776 (the packet will be in queue) then all subsequent packets to the
6777 same remote host must also be put to the queue. Only after the
6778 queue has been purged is it safe again to force the packet
6781 o If you send all packets immediately then it safe to send
6782 any of subsequent packets through the queue, however, after
6783 the first packet is put to queue then any subsequent packets
6784 must also be put to the queue.
6786 Follow these rules and everything works fine.
6788 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6790 * Added new function silc_server_remove_clients_by_server to
6791 remove all client entries from ID list when the server connection
6792 is lost. In this case it is also important to invalidate all
6793 client entires as they hold the invalid server entry. This
6794 fixes fatal bug when server has lost connection and will reconnect
6797 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6799 * Made some sanity checks to silc_server_daemonise like to check
6800 whether the requested user and group actually exists.
6802 * Added sanity check to SKE's silc_ske_responder_finish to check
6803 that the public and private key actually is valid.
6805 * Invalidate the client's nickname when receiving Replace ID
6806 packet and the Client ID is being replaced. This means that the
6807 server will query the nickname if someone needs it (client)
6810 * Sort the ID Cache in client library when the ID Cache data
6811 has changed (needs sorting).
6813 * Do not allow for SILC client to create several connections to
6814 several servers. The client does not support windows right now
6815 and generating multiple connections causes weird behaviour.
6817 Irssi-silc client does support windows and can handle several
6818 connections without problems, see: www.irssi.org and SILC plugin.
6820 * Fixed some places where client was added to the IDList. The
6821 rule of thumb is following (in order to get everything right):
6822 If the client is directly connected local client then the
6823 `connection' argument must be set and `router' argument must be
6824 NULL to silc_idlist_add_client function. If the client is not
6825 directly connected client then the `router' argument must
6826 bet set and the `connection' argument must be NULL to the
6827 silc_idlist_add_client function.
6829 * The funtion silc_server_packet_send_local_channel actually did
6830 not check whether the client was locally connected or not. It
6831 does that now. Fixed a bug related to LEAVE command.
6833 * Fixed Remove Channel User payload parsing bug in server's
6834 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6836 * The server's silc_server_save_channel_key now checks also the
6837 global ID list for the channel as it might not be in the local
6838 list. Fixed a bug related to LEAVE command.
6840 * Is this the end of the [<unknown>] buglet that has been lurking
6841 around for a long time? A little for loop fix in server's
6842 silc_server_command_whois_parse that is used by both IDENTIFY
6843 and WHOIS command. At least, this was a clear bug and a cause
6844 of one type of [<unknown>] buglet.
6846 * WHOIS and IDENTIFY commands call the function
6847 silc_server_command_[whois/identify]_check function even if
6848 we are not router server.
6850 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6852 * Added --with-gmp configuration option. If set the GMP
6853 is always compiled in the SILC source tree. If not set then
6854 it is checked whether the system has the GMP3 installed. If
6855 it has then the GMP won't be compiled (the system's headers
6856 and library is used), if it doesn't have it then the GMP is
6857 compiled in the SILC source tree.
6859 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6861 * Changed RSA private exponent generation to what PKCS #1
6862 suggests. We try to find the smallest possible d by doing
6863 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6864 not security fix but optimization.
6866 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6868 * Added new config entry [Identity] to fork the server and run
6869 it as specific user and group. A patch from Bostik.
6871 * Imported Dotconf configuration library into lib/dotconf.
6872 This will be used to create the SILC configuration files later.
6873 It will appear in the distsribution after this commit.
6875 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6877 * A big code auditing weekend happening. Auditing code for
6878 obvious mistakes, bugs and errors. Also, removing any code
6881 Removed files for being obsolete:
6883 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6884 inline in the file lib/silcutil/silcbuffer.h)
6886 o lib/silcutil/silcbufutil.c (the header has inline versions)
6888 Changed code to fix possible error conditions:
6890 o The buffer formatting routines now check that the destination
6891 buffer really has enough space to add the data. This applies for
6892 both buffer formatting and unformatting
6893 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6894 unformatting was changed to accomodate following rules:
6895 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6896 sent to the function while XXX_*STRING will not allocate or copy
6897 the data into the buffer. Instead it sets the pointer from the
6898 buffer into the pointer sent as argument (XXX_*STRING used to
6899 require that the pointer must be allocated already). This change
6900 makes this whole thing a bit more consistent and more optimized
6901 (note that the data returned in the unformatting with XXX_*STRING
6902 must not be freed now). The routines return now -1 on error.
6904 o Tried to find all code that use buffer_format and buffer_unformat
6905 and added return value checking to prevent formatting and
6906 especially unformatting errors and possible subsequent fatal
6909 o Changed ske->x and ske->KEY to mallocated pointers in
6910 lib/silcske/silcske.h. Fixed possible data and memory leak.
6912 o Added return value checking to all *_parse* functions. Fixed
6913 many memory leaks as well.
6915 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6916 so that buffer overflows would not happen. All code now also
6917 checks the return value as it can fail.
6919 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6921 * Added reconnection support to server if the normal server looses
6922 its connection to the router (for example if router is rebooted).
6923 The server performs normal reconnection strategy implemented
6924 to the server. Affected file silcd/server.c.
6926 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6928 * Added new packet type SILC_PACKET_SET_MODE that is used to
6929 distribute the information about changed modes (for clients,
6930 channels and clients channel modes) to all routers in the
6931 network. Updated the protocol specification accordingly.
6933 Added functions into silcd/packet_send.c and
6934 silcd/packet_receive.c: silc_server_send_set_mode,
6935 silc_server_set_mode.
6937 Added new files silcmode.[ch] into lib/silccore that implements
6938 the encoding and decoding of Set Mode Payload. Added new type
6939 SilcSetModePayload. Moved the definitions of different modes
6940 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6942 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6944 * Oops, a little mistake in server's connection authentication
6945 protocol. The protocol is not ended with FAILURE but with
6946 SUCCESS if the authentication is Ok. :) Affected file is
6949 * Implemented NICK_CHANGE notify handling in server in the file
6950 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6951 the local clients on the channel. After the changing nickname
6952 in router environment snhould work and the [<unknown>] nickname
6953 should appear no more.
6955 The silc_server_replace_id function that receives the Replace ID
6956 payload now sends the NICK_CHANGE notify type also in the file
6957 silcd/packet_receive.c
6959 * Changed WHOIS and IDENTIFY command to support the maximum amount
6960 of arguments defined in protocol specs (3328 arguments). This
6961 fixed a bug that caused problems when there were more than three
6964 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6966 * Added extra parameter, command identifier, to the
6967 silc_client_send_command so that explicit command identifier
6970 Changed that ID list routines uses specific command identifier
6971 when sending WHOIS/IDENTIFY requests to the server so that they
6972 can be identified when the reply comes back.
6974 Affected files lib/silcclient/command.[ch],
6975 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6977 * Added `sender' argument to silc_server_packet_send_to_channel
6978 to indicaet the sender who originally sent the packet to us
6979 that we are now re-sending. Ignored if NULL. Affected file
6980 silcd/packet_send.[ch].
6982 * Added some server statistics support in silcd/server_internal.h
6983 SilcServerStatistics structure and around the server code. Also
6984 send some nice statistics information when client is connecting
6987 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6989 * Fixed channel ID decoding in server's JOIN command reply in
6990 silcd/command_reply.c
6992 * Fixed braodcasting of replace ID payload to not to send it if
6993 we are standalone server in silcd/packet_receive.c.
6995 * Fixed all channel message sending routines to not to send
6996 packets to clients that has router set, since they are routed
6997 separately in the same function earlier. Affects file
6998 silcd/packet_send.c and all channel packet sending functions.
7000 * In USERS reply, res_argv[i] are not allocated, the table
7001 is allocated. Thus changed that free the table, not its
7004 * In server's whois_check and identify_check if the client is
7005 locally connected do not send any WHOIS commands - they are not
7008 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7010 * Fixed some minor bugs in client when sending WHOIS command. The
7011 arguments was in wrong order.
7013 * Removed statis function add_to_channel from server in
7014 silcd/command.c that was previously used with the joining but
7017 * Tested USERS command in router environment successfully with two
7018 routers, two servers and two clients.
7020 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7022 * Reorganized the USERS command and command reply in client library
7023 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
7024 When the command is given by user we register a pending command
7025 callback that will reprocess the command after the reply has been
7026 received from the server. When reprocessing the packet we then
7027 display the information. Thus, the USERS information is displayed
7028 now in the command callback instead of in the command reply
7029 callback. The processing of the command is same as previously
7030 when server has sent the command reply in the JOINing process.
7032 * Added to USERS command in silcd/command_reply.c to join the client,
7033 we didn't use to know about, to the channel after we've created
7034 a client entry for it. Also, for clienet we did know already still
7035 check whether it is on the channel or not and add it if not.
7037 * Removed silc_server_command_join_notify as the function and its
7040 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7042 * Changed the client's pending command handling to the same as the
7043 server's pending command handling. It is also now possible to
7044 execute command reply functions from other command reply
7045 function as the function callbacks for commands and command
7046 replies are one and same. The pending commands are not static
7047 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7048 in client connection context. Thus, pending commands are server
7049 connection specific as it is convenient.
7051 Changed the function silc_client_command_pending and
7052 silc_client_command_pending_del and added new function
7053 silc_client_command_pending_check. Removed the
7054 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7057 * Added cmd_ident, current command identifier, to the client
7058 connection context in lib/silcclient/client.h to keep track on
7059 command identifiers used in command sending. Client's command reply
7060 function handling now supports the mandatory command identifiers.
7062 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7063 funtions in client to fully support pending command callbacks.
7065 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7066 as one of the arguments to the application in the command reply
7069 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7070 before first releasing SILC but came back. Now it is removed again
7071 and should come back nomore. The FORWARDED flag was used only
7072 by the JOINing procedure by forwarding the command packet to router.
7073 Now, the JOINing procedure has been changed to more generic (due
7074 to various router environment issues) and FORWARDED is not needed
7075 anymore for anything. The protocol specification is yet to be
7078 Now, removed silc_server_packet_forward from server and the flag
7079 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7081 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7083 * Renamed NAMES command to USERS command. The NAMES was named that
7084 due to historical reasons. Now it is renamed. Also, rewrote
7085 parts of the USERS command. The nickname list is not sent anymore
7086 by the server. Only Client ID and mode lists are sent in the USERS
7087 command. Changed this also to the protocol specification.
7089 The client now resolves the names and stuff after it receives
7090 the USERS list from the server when joining to the channel.
7092 * WHOIS and IDENTIFY commands has been changed to support multiple
7093 Client ID's per command. One can now search for multiple users
7094 in the network by sending only one WHOIS or IDENTIFY command.
7095 Changed the code and the protocol specifications.
7097 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7098 uses silc_server_command_whois_parse to parse the request. */
7100 * If normal server, do not parse the WHOIS and IDENTIFY requests
7101 before sending it to the router. Saves some time.
7103 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7105 * Fixed JOIN command on client library. Wrong number of arguments
7106 used to crash the client.
7108 * Added silc_server_channel_has_global function to check whether
7109 channel has global users or not.
7111 * Added silc_server_channel_has_local function to check whether channel
7112 has locally connected clients on the channel.
7114 * The silc_server_remove_from_one_channel now checks whether the
7115 channel has global users or not after given client was removed from
7116 the channel. It also checks whether the channel has local clients
7117 on the channel anymore. If it does not have then the channel entry
7118 is removed as it is not needed anymore.
7120 * The silc_server_notify now checks on JOIN notify whether the joining
7121 client is one of locally connected or global. If it is global then
7122 the channel has now global users on the channel and that is marked
7123 to the channel entry. Also, it now saves the global client to
7124 global list who is joining and JOINs it to the channel. This is
7125 for normal server, that is.
7127 Changed silc_server_send_notify_on_channel,
7128 silc_server_packet_relay_to_channel and
7129 silc_server_packet_send_to_channel check if we are normal server
7130 and client has router set (ie. global client) do not send the
7131 message to that client, as it is already routed to our router.
7133 * Implemented LEAVE notify type handling in silc_server_notify
7136 * Tested LEAVE command in router environment successfully. Tested
7137 with two routers, two servers and two clients.
7141 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7143 * Implemented SIGNOFF notify type handling in silc_server_notify
7146 * silc_server_remove_id now removes the client entry from all channels
7147 it has joined and thusly sends SIGNOFF notify type.
7149 * Rewrote the NAMES list generation in server by removing two excess
7150 loops. The lists are created now inside one loop.
7152 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7154 * silc_server_remove_channel_user checks now also global list
7155 for channel and client.
7157 * silc_server_new_channel_user checks now both local and global
7158 list for channel and client. Fixed a bug in client id decoding.
7159 Used to decode wrong buffer.
7161 * silc_server_channel_message checks now both local and global
7162 list for channel entry.
7164 * Tested channel joining (hence JOIN) in router environment
7165 successfully. Tested with two routers, two servers and two
7168 * Tested channel message sending in router environment successfully.
7170 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7172 * Added silc_server_save_channel_key into server.[ch] to save the
7173 received channel key in Channel Key payload processing. It is
7174 also used in JOIN command reply handling.
7176 Equivalent function silc_client_save_channel_key added into
7177 client.[ch] into client library.
7179 * Changed JOIN command reply to send information whether the channel
7180 was created or not (is existing already) and the channel key
7181 payload. Changed protocol specs accordingly.
7183 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7184 the request was sent by ID and not by nickname. Crashed on
7187 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7189 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7190 now correctly save the received data.
7192 * silc_server_free_sock_user_data now notifies routers in the
7193 network about entities leaving the network.
7195 At the same time implemented functions silc_server_remove_id
7196 and silc_server_send_remove_id to receive and send REMOVE_ID
7197 packets. The packet is used to notify routers in the network
7198 about leaving entities. The ID removed will become invalid in
7201 * Added function silc_idlist_del_server into server. Removes and
7202 free's server entry from ID list.
7204 * silc_server_private_message function now checks, if we are router,
7205 that the destination ID really is valid ID, naturally.
7207 * In router when NEW_ID packet is received (for new client) the
7208 hash of the Client ID is saved in the ID Cache but the
7209 client->nickname is set to NULL, instead of putting the hash
7212 IDENTIFY command now also checks that client->nickname must be
7213 valid. If it is not if will request the data from the server who
7214 owns the client. Added new function
7215 silc_server_command_identify_check.
7217 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7218 to set the command to already allocated Command Payload.
7220 * Tested private message sending in router environment with two
7221 routers, two servers and two clients. Fixed minor bugs and now
7224 * Fixed segfault from client's NAMES command. Used to crash if
7227 * Forwarded packets must not be routed even if it is not destined
7228 to the receiver. Changed server code comply with this.
7230 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7232 * Added `require_reverse_mapping' boolean value to ServerParams
7233 structure. If TRUE (not default) the server will require that
7234 the connecting host has fully qualified domain name.
7236 If the reverse mapping is not required and hostname could not be
7237 found the IP address is used as hostname.
7239 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7241 * Implemented version string checking to both client and server.
7242 The check is incomplete currently due to the abnormal version
7243 strings used in development version of SILC.
7245 * Changed all command functions in server to use the new
7248 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7250 * Changed char *data to unsigned char *data in ID Cache system to
7251 support binary data as ID Cache data. Changed code to support
7252 binary data in lib/silccore/idcache.c.
7254 * Renamed silc_server_packet_relay_command_reply to
7255 silc_server_command_reply as it is normal packet receiving
7256 function. Rewrote the function to accept command replys for
7257 servers and not only for clients.
7259 * Mark remote router always as registered server if we are connecting
7260 to it. Otherwise, commands sent by the router to us are ignored.
7262 * All ID List find routines now returns the ID Cache Entry pointer
7263 as well if requested.
7265 * WHOIS command works now in router environment, tested with two
7266 routers, two servers and two clients.
7268 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7269 in router environment (as it is almost equivalent to WHOIS) but
7270 hasn't been tested thoroughly. Added new functions:
7272 silc_server_command_identify_parse
7273 silc_server_command_identify_send_reply
7274 silc_server_command_identify_from_client
7275 silc_server_command_identify_from_server
7277 * Disabled route cache adding because adding two different ID's with
7278 same IP replaces the old cache entry thus giving wrong route.
7279 The entry->router->connection is always the fastest route anyway
7280 so route cache may not be needed. Of course, new routes maybe
7281 established after receiving the ID when the entry->router->connection
7282 might not be anymore the most optimal.
7284 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7286 * Add route cache for received ID for fast routing.
7288 * Added silc_server_packet_route to route received packet on router
7289 that is not destined to us.
7291 * Renamed silc_server_get_route to silc_server_route_get.
7293 * Added id_string and id_string_len fields into SilcServer to
7294 include encoded ServerID for fast comparing without excess
7295 encoding of the ID's.
7297 * Cleaned up WHOIS command on server side. Added following static
7300 silc_server_command_whois_parse
7301 silc_server_command_whois_check
7302 silc_server_command_whois_send_reply
7303 silc_server_command_whois_from_client
7304 silc_server_command_whois_from_server
7306 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7307 arguments in command replies. All command functions should be
7308 updated to use this macro.
7310 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7312 * Minor typo fixes on command reply handling on server.
7314 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7316 * Added silc_server_command_add_to_channel internal routine to add
7317 the client to the channel after router has created the channel and
7318 sent command reply to the server.
7320 * Added generic silc_server_send_command to send any command from
7323 * Use static buffer with ID rendering instead of duplicating data.
7325 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7327 * Fixed a channel user mode bug when joining to a channel server gave
7328 everybody channel founder rights, oops.
7330 * We mark ourselves as the router of the incoming server connection
7331 if we are router ourselves. This way we can check in some packet
7332 sending functions whether it is locally connected server. For
7333 incoming router connections we put NULL.
7335 * For router sending packets locally means now always sending the
7336 packet cell wide; to local clients and local servers. For normal
7337 server sending packet locally means sending it to only local
7340 * Fixed the JOIN command to really work in router environment. If the
7341 channel is created it is always created by the router. Router is
7342 also responsible of making the initial joining to the channel,
7343 sending JOIN notify to the sending server and distributing
7344 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7345 does not exist server doesn't do anything else but forward the
7346 command to the router which performs everything.
7348 * Added silc_server_send_channel_key function to send the Channel Key
7351 * Added silc_server_create_channel_key to create new channel key. The
7352 channel key is now re-generated everytime someone joins or leaves
7353 a channel, as protocol dictates. Note: channel->key_len is the
7356 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7358 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7359 packet_receive.[ch] to separate packet sending and receiving
7360 routines. The server.[ch] now includes everything else including
7361 actual packet processing (writing and reading data) and other
7364 Renamed silc_server_private_message_send_internal to
7365 silc_server_send_private_message. The routine is still though
7366 used only to relay private messages as server does not send
7367 private messages itself.
7369 Renamed silc_server_new_channel to silc_server_create_new_channel
7370 and added new function sicl_server_new_channel that handles the
7371 incoming New Channel packet. Added also new sending function
7372 silc_server_send_new_channel to send New Channel Payload.
7374 * Added new function silc_server_notify to process incoming notify
7375 packet to the server/router. Server may then relay the notify
7376 to clients if needed.
7378 * Added new function silc_server_new_channel_user to process incoming
7379 New Channel User packet. Router will redistribute the packet and
7380 send JOIN notify to its local clients and locally connected servers
7381 if needed. Normal server will send JOIN notify to its local client
7382 on same channel when received this packet. Added also corresponding
7383 sending function silc_server_send_new_channel_user to sent the
7386 * Added boolean route argument to send_notif_to_channel and
7387 packet_send_to_channel functions to attempt to route the packet
7388 if it is TRUE and send only locally if it is FALSE.
7390 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7392 * silc_server_replace_id now broadcasts the received replace ID
7393 packet if it is not broadcast packet already. The router must
7394 broadcast to inform other routers about changed ID.
7396 * Added backpointer to server's router into SilcServer context in
7397 silcd/server_internal.h.
7399 * Fixed silc_server_packet_broadcast to send correct broadcast
7402 * The channel key is now distributed to the local client as soon
7403 as it is received from the router (in router environment) so that
7404 no other packet may be sent for the channel until client has
7407 * silc_server_remove_channel_user now broadcasts the received
7408 Remove Channel User packet if it is not broadcast packet already.
7409 The router must broadcast to inform other routers about removed
7412 * Added users field into SilcPacketContext that is a reference count
7413 of the context. One can increase the reference count by calling
7414 silc_packet_context_dup which is now changed to just increase the
7415 reference count instead of duplicating the data. The reference
7416 count is decresed by calling silc_packet_context_free that will
7417 free the data after the reference count hits zero.
7419 For now on the packet context and everything allocated into it
7420 (including the raw packet from network) must be freed by calling
7421 the new silc_packet_context_free function. Added also new function
7422 silc_packet_context_alloc that must be used now to allocate the
7423 context. This also means that if a routine is asynchronous from
7424 silc_[client/server]_packet_parse_type the packet context must
7425 be duplicated by calling silc_packet_context_dup. Otherwise it
7426 gets free'd after silc_[client/server]_packet_parse_type returns.
7427 Also, one must remember that if packet is duplicated then its
7428 reference count must be decresed by calling the free function as
7429 many times as it was duplicated.
7431 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7432 from both client and server.
7434 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7436 * Made joining to a channel working in router environment.
7438 * Cleaned up JOIN command on server side and create function
7439 silc_server_command_join_channel internal routine to make the
7442 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7444 * Changed silc_command_pending list to SilcDList. Also, added
7445 `ident' field to SilcServerCommandPending structure to identify
7446 the reply and to call correct callback.
7448 Added silc_server_command_pending_check function to replace the
7449 corresnponding macro. The silc_command_pending list is not
7452 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7453 to set identifier to previously allocated Command Payload. It
7454 is used to set identifier for command when resending Command
7457 * Added silc_command_payload_encode_payload to encode Command
7458 Payload buffer from SilcCommandPayload structure.
7460 * Added silc_argument_payload_encode_payload to encode Argument
7461 payload buffer from SilcArgumentPayload structure.
7463 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7465 * Changed WHOIS command to support router connection on server side.
7466 The whois request is always sent to router unless the server is
7467 standalone server. After server has received the reply from the
7468 router will it send the reply to the client.
7470 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7471 broadcast received broadcast packet. The function is used only
7472 by router. The broadcast packet is always sent to the router's
7475 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7476 render given ID to printable string, for log files for example.
7478 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7480 * Made basic router to router connections working. At least they
7481 can now connect to each other but nothing really works the way
7482 they are supposed - yet.
7484 * Added new initiator token to RouterConnection configuration
7485 file in silcd/serverconfig.[ch]. It is used to tell whether we
7486 are the initiator to the remote router or whether we'll expect
7487 the other end to connect.
7489 * Moved registering of listener task to silc_server_init, hence
7490 the server starts listenning as soon as it is run, even if it
7491 does not have connections to other routers. Let's see how well
7494 * Changed default connection retry timeouts for more suitable in
7497 * Removed cipher and such arguments from silc_idlist_add_client
7498 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7499 Added new function silc_idlist_add_data to add the keys and stuff
7502 * Added SilcIDListData structure and added it to SilcClientEntry
7503 and SilcServerEntry as their first field in the structure. This
7504 way we can explicitly cast the ID entries to the SilcIDListData
7505 structure and get common data for the entries. In past, we had
7506 to first check what type of connection it is and then cast it to
7507 correct ID entry type. Now, we can directly cast the opaque
7508 pointer to the SilcIDListData (no matter what ID entry it actually
7509 is) and get the data needed.
7511 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7513 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7514 in some circumstances even if threre were timeout tasks, though not
7515 IO tasks, but tasks anyway. Now fixed.
7517 * Defined SilcServerConnection structure to hold connection specific
7518 stuff about directly connected servers and routers. The definition
7519 is currently in silcd/server_internal.h. I thought about having
7520 a bit more important role fro this struct but for now it is used
7521 only when connecting to other server (or router actually).
7523 * Added connecting retry support in server when connecting to
7524 router(s). The retry feature implement exponential backoff
7525 algorithm. Also, added SilcServerParams structure to hold default
7526 parameters for server. For now, it include these retry settings
7527 and are hard coded. After server is moded to be as Silc Server
7528 Library this structure will be more important.
7530 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7532 * Changed client librarys channel->clients table to SilcList and
7533 changed code accordingly.
7535 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7537 * Changed client's channel table to SilcList and changed code
7538 accordingly. Also changed SilcChannelClientEntry to include back-
7539 pointer to the channel so that client entry can use that structure
7540 as list as well and we have fast cross-reference to the channel.
7541 This change dramatically decreased the complexity of channel
7542 handling with client entry and vice versa (removed one extra
7543 loop when searching for channel entry from many functions).
7545 * Changed server->sim from table to SilcDList and changed code
7548 * NAMES command can now be used from user interface. It will show
7549 the user list on the channel, neatly.
7551 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7552 Code now saves realname of the user if it becomes available.
7554 * Renamed configure.in to configure.in.pre and made ./prepare
7555 script to automatically add correct version string to
7556 configure.in which it creates from configure.in.pre.
7558 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7560 * NAMES command reply now shows users mode with the nickname when
7563 * Moved silc_client_ch[u]mode[_char] functions from
7564 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7565 place sucks, they are utility functions and should be in some
7568 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7570 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7573 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7577 * Added TRQ (efficient deque and list library) into lib/trq. This is
7578 a very good list library that is currently used in the SILC. Defined
7579 SilcList API over the library because I didn't like the API very
7580 much. See lib/trq/silclist.h for the API and examples of how to
7581 use the API. Fixed various places in the code to use the new
7582 SilcList API. The SilcList is meant for lists that has a structure
7583 already defined as a list. It is not suitable to add just some
7584 context to the list (in TRQ, the context is the list actually).
7586 So, I defined SilcDList that can be used for the purpose where
7587 predefined list structure does not exit. This can be used as
7588 such list. Now some context just can be added to the SilcDList.
7589 Currently this list is not used in the SILC just yet, though there
7590 are a lot places where this can replace dynamically allocated
7591 tables and I will fix these places, later, to use SilcDList.
7592 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7593 and use TRQ internally).
7595 Also fixed some annoying warning messages that the original TRQ
7596 code generated. Also minor changes to TRQ's Makefile.in.
7598 * Added support for querying by Client ID to both WHOIS and
7599 IDENTIFY commands into server, as required by the protocol.
7601 * Removed method function pointers from SilcBuffer structure. They
7602 weren't used to anything and just increased the context size for
7603 no good reason. This change also made silc_buffer_alloc and
7604 silc_buffer_free functions inline functions.
7606 * Disabled command flooding detection support until it's fixed so
7607 that it accepts commands in but does not execute them more than once
7610 * Added silc_net_localhost(), to return local hostname, into
7611 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7612 that must be initialized before calling silc_client_init.
7614 * Added new function: silc_server_send_notify_on_channels to send
7615 notify messages to all channels client has joined. It is assured
7616 that the message is sent only once per client.
7618 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7619 lib/silcutil/silcutil.[ch] as silc_format function. The new
7620 function is generic and is used by server as well, not only by
7621 the logging routines.
7623 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7624 the provided version string was not acceptable. Added new function:
7625 silc_ske_check_version into lib/silcske/silcske.h. The function
7626 must be implemented by the application (client or server) and it
7627 does not reside in the SKE library. The function checks the version
7628 string remote end sent.
7630 * Added back pointers (to opaque context and to SilcSocketConnection)
7631 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7633 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7634 duplicate packet context structure.
7636 * Changed `notify' client operation to send same arguments as client
7637 receives from server except for ID's. ID's are mapped to correct
7638 ID entry and that is returned. Also, if channel entry is not sent
7639 by server but the notify is for channel the channel entry is sent
7640 to application (otherwise application doesn't know that it is for
7641 channel (library gets it from packet's Destination ID)).
7643 * Added silc_client_remove_from_channels into client library to
7644 remove a client from all channels it has joined to. Used when
7645 received SIGNOFF notify from server. Added also new function
7646 silc_client_replace_from_channels to replace old ID entry with
7647 new ID entry on all channels. Used when received NICK_CHANGE
7650 * Fixed ID Cache list handling in silc_idlist_get_client in
7651 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7652 to get (or query) client by ID.
7654 * Updated TODO list.
7656 * Added connection authentication status message defined by the
7657 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7658 support for these into the code in client and server side.
7660 * Added generic function silc_client_send_command to send any command
7661 with variable argument list. Application should use this function
7662 to send commands if the command functions provided by the library
7663 does not suite for the application's user interface needs.
7665 * Added new `failure' client operation. Application is notified about
7666 received failure packet if client is executing a protocol. In this
7667 case the protocol's execution has failed.
7669 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7670 is required by the protocol.
7672 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7673 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7676 * Added status flag to SilcSKE object to indicate realtime status
7677 of the SKE protocol.
7679 * Application receives now exactly same command reply arguments as
7680 the library receives from server. However, if ID is received the
7681 corresponding ID entry is returned to the application (eg. Client
7682 ID is mapped to correct SilcClientEntry entry and that is returned).
7683 Changed command_reply client operation due to this change.
7685 * Changed all ID's in commands and in command replys as ID Payloads.
7686 Change affected both client and server side codes.
7688 All ID's sent in SILC network (with execption of ID's in SILC
7689 Packet header) are sent in ID Payload to support variable length
7692 * Server now notifies nick changes and notifies all clients on
7693 the channels about the new nickname (about the new Client ID,
7696 * Implemented CMODE command to change channel modes. Supports all
7697 channel modes defined by the protocol specs except ban and invite
7698 lists. (Also, private channel key mode is supported but support for
7699 setting private channel key in client is missing, thus, this mode
7700 has no effect on client side (except that server requires that the
7701 client uses private channel key and normal channel traffic does not
7704 Also, invite mode works per se, but INVITE command does not work
7705 yet correctly, so you can set channel as invite only channel but
7706 inviting clients to the channel does not work (it is yet to be
7707 thought what's the best way to do it).
7709 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7710 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7711 Implemented CUMODE command to change user's mode on the channel.
7712 Supports all modes defined by the protocol specs.
7714 * Added NAMES command reply to return users modes on the channel.
7716 * Removed unnecessary and slow ciphers from lib/silccrypt.
7718 * Set SO_KEEPALIVE option to connection sockets by default.
7720 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7722 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7723 redefined the Notify Payload into protocol specs.
7725 * Added silc_id_payload_parse_id to get ID directly from raw
7728 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7730 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7731 accept searching by Client ID as well.
7733 * Added support for LEAVE and SIGNOFF notify types in client library.
7735 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7736 to parse ID Payload from raw data.
7738 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7740 * Added flags parameter into silc_ske_assemble_security_properties
7741 function in lib/silcske/silcske.[ch].
7743 * Changed notify client operation to fit better for notify messages
7744 sent by server. The notify payload received from server is now
7745 passed to the application (after parsing it to SilcNotifyPayload).
7746 It is application's responsibility to retrieve the arguments
7747 from the payload and show the message the way it wants. The message
7748 sent by server is implementation specific.
7750 * Changed public keys to comply with the protocol specification.
7751 Old public keys are not supported anymore and are not compatible.
7753 * Removed nickname from Channel Payload as the latest draft removed
7754 it. The client must resolve the nickname from the NAMES command
7755 reply received when it joined the channel.
7757 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7759 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7761 * Fixed some errors in protocol specification drafts.
7763 * Created lib/silccore/silcnotify.c to implement Notify Payload
7764 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7765 generic payloads described by protocol specifications. The file
7766 includes implementations for ID Payload and Argument Payload.
7768 * Changed Command Payload implementation to use the new Argument
7769 Payload. Changed command_xxxx_payload to command_payload_xxxx
7770 to comply with SILC coding conventions.
7772 * Added suppport for Argument Payload handling in Notify Payload
7773 implementation as protocol requires it. Added the new support
7774 into server and client lib as well.
7776 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7778 * Added support for multiple nicknames on same channel. [n] is
7779 added locally to the nickname if there are more than one same
7780 nicknames on the channel.
7782 * Server now sends all nicknames that matched WHOIS request.
7783 Client also shows the list received from server.
7785 * Added TOPIC command to client side. User can now set and show
7786 current topic on channel.
7788 * Added MOTD command to client and server. Also, server sends the
7789 motd when client connects to the server.
7791 * Changed version strings to comply ISO 8601.
7793 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7795 * Fixed protocol error handling in client library. It should now
7796 cope even if the SKE fails for some reason.
7798 * Made new protocol specification drafts for submitting to IETF.
7800 * Implemented TOPIC command to server in silcd/command.c.
7802 * Added two new notify types into lib/silccore/silcnotify.h:
7803 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7804 notify nickname change and topic setting/change on a channel.
7806 * API change of command_reply operation in client library. The
7807 application gets now the status type received from server as well.
7809 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7811 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7813 * Cras fixed and optimized the packet handling even further and
7814 it should work now. Minor change to the prototype of function
7815 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7817 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7819 * Added new function into lib/silcutil/silcschedule.[ch]:
7820 silc_schedule_with_fd to select() a specified fd. The function
7821 returns after timeout expires or data arrives or goes. The
7822 function is used by packet routines to wait that all data is
7823 received from network.
7825 * Fixed data reading from network in lib/silccore/silcpacket.c.
7826 The code now assures that all data is read from the fd and then
7827 continues packet processing. This was a bug fix since the code
7828 used to drop some data in some circumstances.
7830 * Added new function into lib/silcclient/client.[ch]:
7831 silc_client_start_key_exchange to start key exchange after
7832 connection has been established to server. The code internally
7833 now uses this funtion but its main purpose was to provide it
7834 for applications that perform their own connecting. After
7835 application has created a connection it merely calls this
7836 function to start the key exchange between client and server.
7837 The library takes care of everything else after that.
7839 Updated also lib/silcclient/README to explain the usage of
7842 * Do not send to application information that connection has
7843 been established. Application gets notified it by connect
7846 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7848 * Applied cras's patch to add silc_schedule_one function. The
7849 function runs scheduler once and returns.
7851 * Fixed the scheduler after cras messed it up. The timeout
7852 handling works now as it's supposed to work.
7854 * Added into lib/silccore/ silcnotify.h to include notify
7855 message types support. Changed silc_server_send_notify*
7856 functions, in server.[ch], to support those new notify types.
7857 Added the support for the notify types into client library,
7858 as well. Added new notify client operation into ops.h in
7861 * Changed silc_server_packet_send_to_channel to send normal
7862 packets instead of just channel message packets. The function
7863 is now used to send the notify packets to channels. It is not
7864 used to send channel message packets anymore, as server never
7867 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7868 va_arg()s as it seems to require it nowadays. I guess, if SILC
7869 is compiled with older va_arg() the new code should work anyway.
7871 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7873 * Splitted core library. Core library (lib/silccore) includes
7874 now only SILC protocol specific core (and common) components.
7875 Created new utility library (lib/silcutil) that includes more
7876 generic purpose stuff. The stuff for util library was taken
7877 from the old core library. This was minor and easy split.
7879 * Created SILC Client Library (lib/silcclient) that includes
7880 implementation of the SILC client without user interface. This
7881 was major move from silc/ directory. The code has been changed
7882 so that it is transparent towards the user interface. The
7883 silc/ directory includes now the same user interface as before
7884 and it uses the new client library. Read lib/silcclient/README.
7885 Basicly, the client library performs everything else related
7886 to SILC except user interface handling. Also, configuration
7887 files are considered to be part of user interface and library
7888 does not handle them.
7890 This change also changed a lot of structures, function naming etc.
7891 Most important change was that SilcClientWindow object was
7892 renamed to SilcClientConnection in the client library. Created
7893 also new file lib/silcclient/ops.h. Also added new files
7894 silc/local_command.[ch] and silc/client_ops.[ch].
7896 All these changes were made to make it easier for user interface
7897 designers to create what ever user interface for the SILC client
7900 It is also expected that the server will be moved to lib
7901 directory as well and SILC Server Library will be created;
7902 sometimes in the future.
7904 * Removed Local commands from lib/silccore/silccommand.h as
7905 they are application specific and new client library does not
7906 handle any of those anymore.
7908 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7909 old client implementation in silc/.
7911 * Added support for callback functions in SILC_LOG_* macros.
7912 Application can now set its own callbacks that will be called
7913 instead of using the default functions that will always print
7914 the debug messages to stderr (or stdout). Also, debugging can
7915 now be disabled by setting silc_debug to FALSE and re-enabled by
7916 setting it to TRUE. Note, that logging will still work even
7917 if debugging is disabled.
7919 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7920 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7921 silc_log_reset_debug_callbacks.
7923 * To enable debugging in silc client one must give now -d
7924 option on command line.
7926 * Changed silc_schedule_init to automatically allocate task queues
7927 if they are not allocated before calling it.
7929 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7931 * Added GMP 3.1 into math library.
7933 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7935 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7936 a channel in SILC network. The packet is used by servers and
7937 routers to notify other routers that user has left a channel.
7938 This little feature was missing until now. Added the feature
7939 to protocol specification as well.
7941 Added functions: silc_server_send_remove_channel_user and
7942 silc_server_remove_channel_user into server.[ch].
7944 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7945 lib/silccore/silcpacket.h. However, they are not implemented
7948 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7950 * Fixed joining to a channel and sending channel messages
7951 between server and router. The channel message sending should
7952 now work inside a cell.
7954 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7956 * Fixed the private message sending between server and router.
7957 The private message sending should now work inside a cell.
7959 * Added silc_server_replace_id into server.[ch] to replace
7960 existing ID in the SILC network.
7962 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7963 and silc_idlist_replace_server_id into idlist.[ch] in server.
7965 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7967 * Fixed the server to server connections. Server can again now
7968 connect to router. Router to router connections probably does
7971 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7973 * Added dynamic protocol registering support. Now protocols can
7974 registered and unregistered on the fly. Patch by cras.
7976 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7978 * Added lib/contrib directory to hold routines that some platforms
7979 don't have but are needed by SILC.
7981 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7982 into lin/contrib to provide getopt() and getopt_long() for
7983 those who don't have it.
7985 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7987 * Added AWAY command to client. When away message is set and
7988 client receives a private message packet the client automatically
7989 replies to the sender with the away message.
7991 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7992 bug seemed to be the cause of recent problems when compiling
7995 * Added version detection support to SKE protocol specification
7996 and added the new changes to the SKE implementation as well.
7997 There were other minor changes in the SKE protocol as well.
7999 Many changes in lib/silcske/silcske.[ch] and in
8000 lib/silcske/payload.[ch].
8002 * Added ^U functionality, clear input line. Patch from cras.
8004 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8006 * Mainly small bugfixes on core library. Fixed some debugging
8007 logging and buffer overflow in silclog.c.
8009 * Updated config.sub and config.guess on the distribution tree.
8011 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8013 * Added command lagging support in server. Client may execute
8014 commands now only once in two seconds.
8016 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8018 * Optimized packet reception. MAC computation and checking is now
8019 also more optimized. A lot previously duplicated code is now
8020 used as generic by both client and server.
8022 * Fixed key pair generation in clientutil.c
8024 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8026 * Added into lib/silccore/silcbufutil.[ch] new function;
8027 silc_buffer_realloc.
8029 * Moved generic packet sending/encryption functions to
8030 lib/silccore/silcpacket.[ch] from client and server. Some
8031 rewriting of the functions.
8033 * Moved all generic packet reception/decryption functions to
8034 lib/silccore/silcpacket.[ch] from client and server. The
8035 packet processing is now much cleaner in both client and server.
8036 These were major changes in both client and server.
8038 * Created many common functions in server to do packet sending.
8039 Previously code were duplicated a lot, this has been removed
8042 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8044 * Rewrote major parts of the ID cache system. Don't know
8045 whether it is better now or not but at least the API is more
8048 * Major rewrite on ID cache stuff on client because of the ID
8049 cache API changes. Added idlist.c to client.
8051 * Also major rewrite on ID cache stuff on server as well.
8052 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8053 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8054 in hand, instead they are all put into the ID cache system now.
8055 All server_idlist_* routines uses ID cache now instead of
8056 traversing its own lists (those lists does not exist anymore).
8057 SilcIDList though still exists. Also, SilcXXXEntry's are
8060 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8062 * Finally made the SKE implementation compliant to the protocol
8063 specification. All mp integers are now binary encoded as
8064 opposed being HEX encoded.
8066 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8069 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8070 functions: silc_[encode/decode]_pem. Also added function
8071 silc_encode_pem_file to PEM encode with newlines ('\n') for
8074 * SILC public keys are now encoded either PEM or binary. Same
8075 option is for private keys as well. By default private keys
8076 are binary encoded and public keys PEM encoded. Silly HEX
8077 encoding were removed.
8079 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8080 function to create fingerprints.
8082 * Fixed a bug in SHA1; does not change the original data anymore.
8084 * Partly implemented INFO command on client and server side.
8085 Fixed CLEAR command. Changes to SERVER command; show current
8086 server(s) when giving command without arguments. Added
8087 VERSION command to client.
8089 * Added check to server that unregistered connections cannot
8090 execute commands (unless it is specificly allowed).
8092 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8094 * Fixed screen refresh.
8096 * Fixed channel joining bug from client. On some circumstances
8097 client tried to join to a channel it had already joined.
8099 * Added public key verification process into client's protocol.c.
8100 The client now verifies the public key from user and saves
8101 it into ~./silc/serverkeys/ directory.
8103 Added into: clientutil.[ch]: silc_client_verify_server_key.
8105 * Changed SKE protocol's silc_ske_initiator_finish function
8106 to accept callback function that verifies the received public
8107 key. Removed old silc_ske_verify_public_key function.
8109 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8111 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8112 silc_pkcs_private_key[_data]_set.
8114 * Made the password and public authentication more cleaner in
8115 server's protocol.c.
8117 * Removed historic and obsolete protocol `channel_auth' from
8118 both client and server.
8120 * Removed wrong way of sending command status messages from
8121 server to client in server's command.c. The old way violated
8122 protocol specification.
8124 Changes to silccore/silccommand.[ch]: removed
8125 silc_command_encode_status_payload -> not needed anymore,
8126 changed silc_command_encode_payload_va to accept extra
8127 argument on variable argument list. The argument type must
8128 now be provided to the function. Also, added new function:
8129 silc_command_encode_reply_payload_va which is same as
8130 normal command_encode_payload_va except command status type
8131 is provided as extra argument.
8133 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8135 * Added ~./silc directory handling. The directory includes the
8136 public and private keys for the client.
8138 Added silc_client_check_silc_dir, silc_client_create_identifier
8139 and silc_client_load_keys.
8141 * Implemented SILC protocol compliant public key. Added public
8142 and private key saving to and loading from files.
8144 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8145 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8146 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8147 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8148 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8150 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8151 silc_pkcs_load_[public/private]_key.
8153 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8155 * Added silc_server_get_route (route.[ch]) to get connection
8156 data for the fastest route for given ID.
8158 * Implemented INVITE command on client and server. The command
8159 were re-defined in the SILC Protocol Specification and the
8160 implementation now complies with the specification.
8162 * Implemented PING command on client and server.
8164 * Implemented NAMES command on client and server. The server side
8165 supports currently only normal server not router server yet.
8166 Some changes to NAMES definition in SILC protocol specification.
8168 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8170 * Implemented LEAVE command on client and server.
8172 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8173 again. This change was made to the protocol as well. Server
8174 should not violate the protocol specification anymore.
8176 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8178 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8179 was tested. SOCKS4 was not but should work anyway.
