7 Fri Apr 12 20:09:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
9 Added resolve_cmd_ident field to the SilcClientEntry structure
10 too so that if the entry is for example being resolved so
11 another command may attach to the same pending command reply
12 without requiring to resolve the same entry again. Added
13 support for adding multiple pending commands for one
14 command idenfier. Affected files lib/silcclient/command.[ch],
15 lib/silcclient/command_reply.[ch], lib/silcclient/idlist.h.
17 Fri Apr 12 10:17:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
19 * Defined that server receives WHOIS command reply for private
20 and secret channels too. Updated protocol specs and the
21 code in server. Affected file silcd/command.c.
23 * Defined <channel user mode list> argument to WHOIS command
24 reply for returning user modes on the channels. The
25 channel list now doesn't include the user mode anymore but the
26 actual channel mode. Updated protocol specs and the code in
27 client and server. Affected files are silcd/command_reply.c,
28 silcd/command.c, silcd/server.c, irssi/src/silc/core/client_ops.c,
29 and lib/silcclient/command_reply.c.
31 * Save the channels list in WHOIS command reply in normal server
32 so that WHOIS always shows joined channels also in normal
33 server and not just on router. Affected file is
34 silcd/command_reply.c.
36 Thu Apr 11 22:29:33 EEST 2002 Pekka Riikonen <priikone@silcnet.org>

42 Thu Apr 11 16:32:08 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
44 * Changed the UMODE's mode mask argument to be optional. If
45 not provided then the command merely returns the current mode
46 mask to the client. Updated protocol specs and the server.
47 Affected file is silcd/command.c.
49 * Added SILC session detachment/resuming support. It is possible
50 to detach by closing the network connection and then re-connect
51 and resume to the old client session. Added DETACHED user
52 mode that server will set for detached client. Added new
53 packet RESUME_CLIENT which is used to perform the resuming
54 process. Added DETACH command. Updated the protocol specs,
55 core library, client and server. Protocol TODO #22. Very
56 many affected files around the tree.
58 Wed Apr 10 16:32:01 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
60 * Changed the CMODE's mode mask argument to be optional. If
61 not provided then the command merely returns the current mode
62 mask to the client. Updated protocol specs and the server.
63 Affected file is silcd/command.c.
65 * Changed the Killer's Client ID in KILLED notify to be just
66 any ID payload since router server is allowed to kill as well.
67 Updated protocol specs, client libary and server. Affected
68 files are lib/silcclient/client_notify.c, silcd/packet_receive.c,
69 and irssi/src/silc/core/client_ops.c.
71 Tue Apr 9 17:15:42 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
73 * Added new user modes ANONYMOUS for special anonymous servers
74 that may set the mode for client, and BLOCK_PRIVMSG which
75 client may set to block incoming private messages unless the
76 Private Message Key flag is set (using private keys to protect
77 private messages). Updated protocol specs and code in client
78 and server and core library. Protocol TODO #23. Affected
79 files are lib/silccore/silcmode.h, silcd/server.[ch],
80 irssi/src/silc/core/client_ops.c, silcd/packet_receive.c,
81 irssi/docs/help/in/umode.in, lib/silcclient/command.c.
83 * Added new channel user mode BLOCK_MESSAGES which the client
84 may set to itself to tell server not send channel messages.
85 Other packets such as channel key packets are still sent.
86 Protocol TODO #23. Updated the protocol specs, client and
87 server. Affected files are lib/silccore/silcmode.h,
88 irssi/docs/help/in/cumode.in, lib/silcclient/command.c,
89 lib/silcutil/silcutil.c, silcd/command.c, and
92 Mon Apr 8 23:57:32 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
94 * Redefined the Status Payload to include now two 8 bit fields,
95 instead of one 16 bit field. This now makes it possible to
96 send list of errors. Updated the protocol specs and the code
97 in core library, client library and server. Protocol TODO #1.
98 Affected files are lib/silccore/silccommand.[ch],
99 lib/silcclient/command_reply.[ch], silcd/command.c,
100 silcd/command_reply.c and silcd/packet_receive.[ch].
102 Mon Apr 8 19:57:40 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
104 * Added config parse status SILC_CONFIG_EPRINTLINE, this status
105 must be handled by the application and should tell the application
106 that an error message was already printed, and it should print the
107 config coords (line, filename, ...). Affected files are
108 silcd/serverconfig.c, lib/silcutil/silcconfig.[ch].
110 * Added local macro SILC_SERVER_CONFIG_ALLOCTMP to make the
111 server config parsing code more readable.
113 Fixed a bug in the fetch_logging() config callback.
115 Affected files is silcd/serverconfig.c.
117 * Drop root privileges when started in foreground. Don't drop them
118 if debugging also. Affected file is silcd/silcd.c.

127 irssi/docs/help/in/umode.in and lib/silcclient/command.c.
129 Sun Apr 7 17:07:59 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
131 * Added STATS command to the protocol after all, to return
132 various statistical information about the network. It can
133 be used by clients to retrieve statistical information, and
134 servers may use it to to fetch cell and network wide
135 statistics from router. Updated the protocol specs and
136 implemented it to the server. Protocol TODO #16.
137 Affected files are lib/silccore/silccommand, silcd/command.[ch],
138 silcd/command_reply.[ch].
140 Sat Apr 6 17:08:58 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
142 * The LIST command reply in client libary now adds new channel
143 entry if the returned channel doesn't exist yet in cache,
144 and returns the channel entry to the application in the
145 command_reply client operation. Affected file is
146 lib/silcclient/command_reply.c.
148 * Changed the channel message payload's MAC generation to
149 include the IV in the MAC as well. This way all relevant
150 parts of the channel message payload are authenticated also
151 with the channel message MAC (and not only by packet MAC).
152 Causes incompatibility with 1.0 protocol. Protocol TODO #7.
153 Affected file is lib/silccore/silcchannel.c.
155 * Fixed the SKE to save the remote version, since the
156 silc_ske_parse_version mistakenly checked wrong version,
157 after it replaced the start payload. Affected files are
158 lib/silcske/silcske.[ch].
160 Fri Apr 5 16:03:03 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
162 * Splitted lib/silcutil/silcutil.h into silcstrutil.h for

164 silc_utf8_[encode/decode/valid] for UTF-8 string encoding.
165 Affected files lib/silcutil/silcstrutil.[ch].
167 * Renamed silc_*_pem functions to silc_pem_* functions. Affected
168 files are lib/silcutil/silcstrutil.[ch].
170 * Defined that the security property fields in SKE SHOULD be
171 UTF-8 encoded, defined that version string MUST be US-ASCII
172 encoded, defined that passphrases sent in connection
173 authentication protocol MUST be UTF-8 encoded. Implemented
174 these to the client and server. Defined also that other
175 passphrases sent in the protocol MUST be UTF-8 encoded.
176 Affected files are lib/silcske/silcske.c,
177 lib/silcclient/protocol.c, silcd/protocol.c,
178 silcd/serverconfig.c, and lib/silccore/silcauth.c.
180 * Changed the silc_client_close_connection interface to not
181 need the SilcSocketConnection which should not be visible
182 to application. Affected files are lib/silcclient/client.c
183 and lib/silcclient/silcclient.h.
185 * Rewrote the text for Private Message Key Payload in the
186 protocol specification. Protocol TODO #11.
188 Wed Apr 3 16:24:51 EEST 2002 Pekka Riikonen <priikone@silcnet.org>
190 * Upgraded the protocol version to 1.1, updated protocol specs

200 it to protocol specs and implemented it to client and server.
201 Protocol TODO #13. Affected files are silcd/command.c,
202 silcd/packet_receive.c, packet_send.[ch],
203 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
204 The killer's client entry is now returned to application in
205 the `notify' client operation.
207 * Fixed the Max Argument fields that had too large value set
208 in the protocol specs. Protocol TODO #14.
210 * Added the LEAVE command reply to return the ID of parted
211 channel. Updated protocol specs and implemented it to the
212 client and server. Protocol TODO #15. Affected files are
213 silcd/command.c, lib/silcclient/command_reply.c. The channel
214 entry is now returned to application in the `command_reply'
217 * Rewrote the version SKE version checking in client libary
218 and in server to use the silc_parse_version_string. Affected
219 files are lib/silcclient/protocol.c, silcd/protocol.c.
221 * Added SILC_STATUS_ERR_NO_CHANNEL_FOPRIV error status to few
222 commands that was missing it, and updated protocol specs and
223 the server implementation. Protocol TODO #10. The affected
224 file is silcd/command.c.
226 * Defined new message flags SILC_MESSAGE_FLAG_REPLY to be
227 generic reply to a generic request (REQUEST flag), and
228 SILC_MESSAGE_FLAG_DATA to send any kind of data in a generic
229 way. A draft-riikonen-silc-flags-payloads-00.txt is written
230 to define the payload for DATA flag. Added the flags to
231 the implementation. Protocol TODO #9. Affected file is
232 lib/silccore/silcchannel.h.
234 Changed the client library to return the message length
235 to application as well in the channel_message and private_message
236 client operations. Affected files are
237 lib/silcclient/client_prvmsg, lib/silcclient/client_channel.c,
238 lib/silcclient/silcclient.h, irssi/src/silc/core/client_ops.c,
239 and lib/silcclient/client_ops_example.c.
241 * Added two new channel modes: SILC_CMODE_SILENCE_USERS
242 and SILC_CMODE_SILENCE_OPERS which can be used to moderate
243 the channel. Updated protocol specs and impelemented this
244 to client and server. Protocol TODO #6. Affected files are
245 silcd/packet_receive.c, server_util.c, lib/silcclient/command.c,

248 Added new options m and M to CMODE command in Irssi SILC
249 client to set these modes.
251 * Deprecated all administrative commands from SILC protocol
252 since they are highly implementation specific commands.
253 Updated protocol specs. Moved the old commands in
254 implementations to private range of command types. Affected
255 files are silcd/command.c, lib/silcclient/command.c and
256 lib/silcclient/command_reply.c. Protocol TODO #8.
258 * Fixed a bug in server where sending unknown command crashes
259 the server. Affected file silcd/command.c.
261 Wed Apr 3 09:57:47 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
263 * Added SILC_PROTOCOLVERSION macro to check protocol version
264 of a socket connection. The affected file is
265 lib/silcutil/silcsockconn.h.

274 Affected file silcd/protocol.c.
276 Tue Apr 2 14:55:06 CEST 2002 Pekka Riikonen <priikone@silcnet.org>
278 * Some client implementations quit network by doing first LEAVE
279 and then immediately SIGNOFF (like Bombyx). We now do check
280 after a short time after LEAVE notify and check whether the
281 client is still valid after LEAVE, and if not we remove it from
282 cache. Affected file is lib/silcclient/client_notify.c.
284 Tue Apr 2 13:39:04 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
286 * Merged version 1.1.4 of zlib. Even if it not currently in use,
287 it's good not to have security holes here.
289 * Fixed a negative refcount situtuation for the config context.
290 Affected file is silcd/serverconfig.c.
292 Mon Apr 1 20:15:10 CEST 2002 Johnny Mnemonic <johnny@themnemonic.org>
294 * ROBOdoc documented lib/silcutil/silcutil.h.
296 Sat Mar 30 21:06:45 EET 2002 Pekka Riikonen <priikone@silcnet.org>
298 * Optimized even more the SilcPacketContext structure. Now
299 totally saved 16 bytes of memory per context after optimization.
300 Affected files are lib/silccore/silcpacket.[ch].
302 * Made strict checks for valid SILC IDs. Affected file is
303 lib/silccore/silcid.c.
305 Sat Mar 30 18:15:55 EET 2002 Pekka Riikonen <priikone@silcnet.org>

310 silchash.[ch], silchmac.[ch] and silcpkcs.[ch].
312 * Changed the silc_get_username and silc_get_real_name to
313 never fail. Affected file lib/silcutil/unix/silcunixutil.c.
315 * Fixed the Irssi SILC Client to use the silc_get_username and
316 silc_get_real_name insted of glib routines since the glib
317 routines only corrupt stack. Fixes the Irssi SILC to work in
318 Cygwin. Affected file irssi/src/silc/core/silc-core.c.
320 * Fixed the Irssi to not use g_get_home_dir since it crashes
321 or returns garbage on cygwin and corrupts stack. Added function
322 get_home_dir to Irssi routines. Affected files are
323 irssi/src/core/misc.[ch] and irssi/src/core/core.c.
325 Fri Mar 29 21:55:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
327 * Made some structure optimizations. SFTP memory FS MemFSEntry
328 entry structure. Optimized SilcTask structure. Optimized
329 SilcPacketContext structure.
331 Affected files lib/silcsftp/sftp_fs_memory.c,
332 lib/silcutil/silcschedule.c, lib/silccore/silcpacket.h.
334 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
336 * And yet again reverted back the config thing since Johnny
337 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
340 * Fixed memory leaks from config object. Affected files are
341 silcd/serverconfig.[ch].
343 * Added support for adding new connections to the server in rehash.
344 After rehash they take effect.
346 Added support for changing the maximum allowed connections in
347 rehash. The number can grow but going smaller is not supported.
349 Added function silc_server_num_sockets_by_remote to the
350 silcd/server_util.[ch].
352 Affected files are silcd/server.c, and silcd/serverconfig.[ch].
354 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
356 * Added preliminary checking during config parsing for a valid
357 public/private key and removed further checks in the code.
358 Affected files are silcd/serverconfig.[ch], server.c.
360 * Moved functions silc_server_drop() and silc_server_daemonise()
361 from server.c to silcd.c since they are stricly related to
362 the application activity.
364 * Reverted a small part of the automatic ref/unref since
365 it caused a double unref in some situations. Affected
366 files are silcd/silcd.[ch], server.c, serverconfig.c.
368 * Added some .cvsignore files in the lib directory.
370 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
372 * Fixed silc_net_gethostbyaddr to correctly resolve by
373 address. Affected file lib/silcutil/silcnet.c.
375 * Fixed the notify relaying to client. The HMAC to be used
376 with relayed packets ws wrong and caused decryption failure
377 at the client end. Affected file is silcd/packet_receive.c.
379 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
381 * Created new branch silc_protocol_1_0_branch.
383 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
385 * Changed the silc_server_config_* routines to be SilcServer
386 independent. They are now officially application specific code
387 and not part of generic server implementation. Affected files
388 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
390 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
392 * Added automatic referencing of config context in the
393 silc_server_config_alloc, and automatic unreferencing in the
394 silc_server_config_destroy. Affected files are
395 silcd/serverconfig.[ch], silcd/silcd.c.
397 * Fixed the silc_log_quick handling in the logging routines.
398 It didn't log quickly when it was TRUE. Affected file is
399 lib/silcutil/silclog.c. Also the flush delay was set even
400 if it was 0 in config file. Affected file is
401 silcd/serverconfig.c.
403 * Added support for changing key pair of the server in rehash.
404 Affected file silcd/server.c.
406 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
408 * Fixed the TOPIC_SET notify to not cras. It changed the topic
409 too early, before getting the channel entry. Affected file
410 is silcd/packet_receive.c.
412 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
414 * Added functions silc_server_config_[ref/unref], these are used
415 to prevent that the config object is destroyed.
417 No longer directly affect global variables silc_log_quick and
418 silc_log_delay, they are first cached inside the config object
419 and then applied with silc_server_config_setlogfiles().
421 silc_server_config_set_defaults() is now internal to
422 serverconfig.c, there are no reasons to show this internal stuff
425 Affected files are silcd/serverconfig.[ch].
427 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
428 fprintf's to stderr, since some code may be executed again after
429 the server went into the background. Affected files are
432 * Added rehash support. Added function silc_server_rehash() that
433 will perform all the basic tasks of the rehashing procedure.
435 * Added command line option `-x, --hexdump'. This will enable the
436 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
437 The option `--hexdump' implies `--debug'.
439 * Fixed a bad bug in the logging APIs (silcutil library) where
440 the application would crash after calling silc_log_reset_all().
442 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
444 * Fixed the KICKED notify handling in client library to
445 correctly remove the channel and all entries from the
446 channel when I was kicked. This bug crashed the client.
448 Fixed yet another but in KICKED notify handling to remove
449 the kicked client correctly from the channel.
451 Affected file is lib/silcclient/client_notify.c.
453 * Fixed a minor bug in looking up correct client entry
454 in KICKED notify in server. Affected file is
455 silcd/packet_receive.c.
457 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
458 sources correctly to distribution. Fixes --with-gmp option.
460 * Removed the manual rehashing from ID Cache, and changed it
461 to use the SILC Hash Table's auto rehash feature. Affected
462 file is lib/silccore/silcidcache.c.
464 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
466 * Fixed a bug in the silc_client_nickname_format function that
467 handles the multiple same nickname formatting. Two clients
468 with same nickname caused problems after the first one left
469 and rejoined. It didn't format the nickname correctly.
470 Affected file is lib/silcclient/idlist.c.
472 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
474 * Don't change the topic if olod topic is same as new one.
475 Affected file is silcd/packet_receive.c.
477 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
479 * Added cross-reference support to the SILC Documentation
480 generator. All types across all HTML files are now cross-
481 referenced. Affected files util/robodoc/generator.c and
482 scripts/silcdoc/silcdoc.
484 * Added file lib/silcutil/silctypes.h to include all the
485 arithmetic type definitions and some macros. Removed
486 includes/bitmove.h and moved macros to silctypes.h.
488 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
490 * Merged bugfixes for Irssi SILC client from irssi.org CVS.

495 now returns the type of the ID to the sent pointer. Affected
496 file is lib/silccore/silcid.[ch].
498 * Added check for CMODE_CHANGE notify type that mode change is
499 allowed by the sender. Affected file silcd/packet_receive.c.
501 * Added check for CUMODE_CHANGE notify type that mode change is
502 allowed by the sender. Affected file silcd/packet_receive.c.
503 Added the ID type as CUMODE_CHANGE notify type as argument
504 to the `notify' client operation. Affected files are
505 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
507 * Added function silc_client_add_server to the client library.

513 status from the command reply's argument payload. Affected files
514 are lib/silccore/silccommand.[ch].
516 * Added check for KICKED notify type that the kicking is
517 allowed by the client. Affected file silcd/packet_receive.c.
519 * Created function silc_get_input which can be used to get input
520 (echo on or off) from user on command line. Affected files are
521 lib/silcutil/silcutil.[ch].
523 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
525 * Optimized silc_server_packet_relay_to_channel function.
526 Added new function silc_channel_message_payload_encrypt which
527 can be called directly if channel message payload needs to
528 be encrypted and is already encoded (no need to call _encode
529 function). Packet relaying is now done by router without any
530 extra memory allocations. Affected files are
531 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
534 * Fixed the INVITE notify handling. It took wrong arguments
535 as invite list and invite delete. Affected file is
536 silcd/packet_receive.c.
538 * Added check for TOPIC_SET notify type that the topic change is
539 allowed by the client. Affected file silcd/packet_receive.c.
541 * Added check for INVITE notify type that inviting is allowed by
542 the client. Affected file silcd/packet_receive.c.
544 * Changed the silc_server_client_on_channel to return the
545 SilcChannelClientEntry as well. Moved the function
546 silc_server_check_cmode_rights to server_util.[ch].
547 Affected files are silcd/server_util.[ch], silcd/command.c.
549 * Added function silc_server_check_umode_rights to check whether
550 changing client's user mode is allowed. Added check for
551 UMODE_CHANGE notify type that the umode change is allowed
552 by the client. Affected files are silcd/server_util.[ch],
553 silcd/packet_receive.c and silcd/command.c.
555 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
557 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
558 ID length. It ignored that ID can be IPv6 based as well.
559 Affected file lib/silccore/silcpacket.h.
561 * Fixed the silc_id_id2str and silc_id_str2id to take the
562 IPv6 address offset's into consideration. Affecte file is
563 lib/silccore/silcid.c.
565 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
567 * Fixed the internal Unix scheduler functions to check for
568 NULL context they may receive. The affected file is
569 lib/silcutil/unix/silcunixschedule.c.
571 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
573 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
574 can specify different directory with --home command line
575 parameter. Affected files irssi/src/silc/core/client_ops.c,
578 * SILC-specific commands aren't now executed if the active server
579 isn't of SILC-type, so there won't be problems with having
580 IRC and SILC protocol support in same client. Affected files
581 irssi/src/silc/core/silc-channels.c, silc-servers.c,
584 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
586 * Improved the signal support in SILC Schedule. Added new
587 function silc_schedule_signal_call which is used by application
588 to mark a signal to be called. It is now safe to perform
589 any kind of tasks in signal callbacks since it is guaranteed
590 that the application specified signal callback is called
591 after the signal is over. Affected files are
592 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
594 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
596 * Added `name' field to SilcChannelPrivateKey to represent
597 application given name for the key. Moved also the context from
598 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
599 Added the `name' argument also to the function
600 silc_client_add_channel_private_key.
602 Added function silc_client_current_channel_private_key to set the
603 current channel private key in use.
605 Added "change" command to KEY command which can be used to change
606 the current channel private key. Bound the command also to
609 Also affected files lib/silcclient/client_channel.c,
610 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
612 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
614 * Added silc_rng_get_byte_fast function in to the
615 lib/silccrypt/silcrng.[ch].
617 * Changed the interface of silc_packet_assemble and the
618 silc_packet_send_prepare. If silc_packet_assmble is now
619 called the application does not call silc_packet_send_prepare
620 because the library will call it automatically. These
621 interfaces now also return a reference to the outgoing buffer
622 which includes the assembled packet, which the application can
623 use to encrypt the packet.
625 Affected files are lib/silccore/silcpacket.[ch],
626 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
627 silcd/packet_send.c, server_backup.c and packet_receive.c.
629 * Fixed a packet sending bug on very high load, where outgoing
630 packet queue wasn't handled correctly and packets got corrupted.
631 Affected files are lib/silcutil/*/silc*sockconn.c,
632 lib/silcclient/client.c and silcd/server.c.
634 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
636 * Added macro SILC_PACKET_DATALEN which can be used during
637 packet assembling to check whether the data to be added to
638 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
639 len is truncated until it fits it.
641 Added checks for maximum length of channel message payload and
642 private message payload also.
644 Added checks for maximum packet length in server and in
647 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
648 lib/silcclient/client.c, lib/silccore/silcchannel.c and
649 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
650 lib/silcclient/client_prvmsg.c.
652 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
654 * Added silc_server_packet_queue_purge call to the
655 silc_server_disconnect_remote to assure that all data in the
656 queue before disconnecting is sent to the network. Affected
659 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
661 * Added the deleting of server's own ID cache entry to the
662 silc_server_free function. Free also everything else that
663 has been allocated in silc_server_init. The affected file
666 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
668 * Added functions silc_parse_version_string, silc_version_to_num,
669 and silc_ske_parse_version to parse SILC protocol style version
670 strings. Affected files lib/silcutil/silcutil.[ch] and
671 lib/silcske/silcske.[ch].
673 * Added new configuration params: version_protocol, version_software
674 and version_software_vendor to specify what version the remote
675 host must at least be to be able to connect to server. The vendor
676 string can be regex matched too. Added new function
677 silc_server_connection_allowed to check maximum number of allowed
678 connections, and allowed versions for incoming connections.
679 Affected files are silcd/server.c, server_util.[ch] and
682 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
684 * Added preliminary support for signals in scheduler. The
685 signals we care about are now blocked always when the scheduler
686 is locked. This way we can synchronise the use of signal with
687 scheduler. It is guaranteed that when signal occurs the scheduler
688 is not locked, and thus new tasks can be safely added to the
691 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
692 to silc_schedule_internal_init and silc_schedule_internal_uninit.
693 Added new platform specific routines
694 silc_schedule_internal_signals_[un]block and
695 silc_schedule_internal_signal_[un]register.
697 Added new functions to SILC Schedule API:
698 silc_schedule_signal_[un]register. Each signal that application
699 is going to use should be registered to the scheduler.
701 Affected files are lib/silcutil/silcschedule.[ch],
702 lib/silcutil/*/silc*schedule.c.
704 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
706 * Check for unauthenticated client and server in the
707 silc_server_new_client and silc_server_new_server functions.
708 Affected file silcd/packet_receive.c.
710 * Added function silc_string_is_ascii to check whether given
711 string is 7-bit ASCII string. Affected files are
712 lib/silcutil/silcutil.[ch].
714 * Added function silc_id_is_valid_server_id into the
715 silcd/serverid.c and added checking for valid Server ID's in
716 silc_server_new_server. The Server ID must always be based
717 on the server's public IP address.
719 * Added logging of DISCONNECT packet message in the server.
720 Affected file silcd/server.c.
722 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
724 * Changed all library interfaces that use Global RNG to also
725 accept SilcRng as argument. Affected files are
726 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
727 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
728 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
729 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
732 * Added function silc_pkcs_generate_key to the
733 lib/silccrypt/silcpkcs.[ch] for applications so that they
734 don't need to do pkcs->pkcs->init calls anymore.
736 * Remove SilcSocketConnection from the SFTP API since it really
737 wasn't needed there. The application has the information
738 saved in its contexts anyway and the SFTP layer doesn't need
739 know about it. Affected files lib/silcsft/silcsftp.h and
740 lib/silcsftp/sftp_[server/client].c.
742 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
743 The SilcSimContext is not SilcSim.
745 * Fixed possible buffer overflows in silc_id_render in the
746 lib/silcutil/silcutil.c.
748 * On EPOC the global crypto module lists are not used at all
749 in the crypto library. Added support for using the constant
750 algorithm list on EPOC. Affected files are
751 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
754 * Fixed the handling of third parameter of KICKED notify, since
755 it was mistakenly updated to SILC Protocol 1.0 even though it
756 is to be included in 1.1. Since it is not in 1.0 it is not
757 mandatory, and this fix now handles it only if it is provided,
758 and it is not error if it is not provided. Affected file
759 lib/silcclient/client_notify.c.
761 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
763 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
764 client. Affected file irssi/src/silc/core/client_ops.c.
766 * Merged with Irssi 0.8.4 from irssi.org CVS.
768 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
770 * Check for valid socket connection in client entries before
771 sending any messages. Fixes a crash, but doesn't fix some
772 other underlaying bug that is lurking there. Affected
773 file silcd/packet_send.c.
775 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
777 * $usermode, $cumode and $cumode_space expandos shouldn't do
778 anything with non-SILC server records. Affected file
779 irssi/src/silc/core/silc-expandos.c
781 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
783 * Fixed the silc_net_check_[host/local]_by_sock to support
784 IPv6 bound sockets as well. Now they can return IPv6 addresses
785 as well. Affected file lib/silcutil/silcnet.c.
787 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
788 Affected lib/silcutil/unix/silcunixnet.c.
790 * Fixed ID rendering (at least on some platforms, not NetBSD)
791 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
793 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
795 * Added silc_hash_public_key and silc_hash_public_key_compare
796 functions to be used with SilcHashTable. They can be used to
797 hash public keys and compare public keys in hash table. Affected
798 file lib/silcutil/silcutil.[ch].
800 * Added support for specifying multiple public keys for Client
801 connection section in server configuration file. This makes it
802 possible to accept multiple public keys from same host, or to
803 make a section that accepts any incoming host, and have the
804 accepted public keys listed in the section.
806 Added functions silc_sever_[find/get]_public_key, added the
807 support for this actually to all connection sections but only
808 the Client section is currently allowed to specify multiple
811 Affected files are silcd/server.c, server_internal.h,
812 command.c, protocol.c, server_util.[ch], packet_receive.c.
814 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
816 * Merged Irssi 0.8.2 from irssi.org CVS.
818 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
820 * If silc_debug is TRUE, also output standard logging messages
821 to stderr with the debug output.
823 Made silc_log_reset_all() flushing all channels before returning.
824 Also fixed some documentation typos.
826 Affected files are lib/silcutil/silclog.[ch].
828 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
830 * Fixed the server to check correctly the amount of connections
831 from single host, by checking also the type of the connection.
832 Fixed also the comparison of number of connections and number
833 of allowed connections. Affected files are silcd/server.c,
836 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
838 * Fixed the USERS command reply to save the user's mode on the
839 channel as well. Fixed JOIN command reply to check whether a
840 client is on channel already and not join it twice. Affected
841 file lib/silcclient/command_reply.c.
843 * Added new file silc-expandos.c into irssi/silc/core/ to return
844 various stuff for various signal for the statusbar etc. updating.
845 Now Irssi SILC client prints channel user modes etc. on the
848 * The user mode (like server/router operator changes) is now shown
849 on the Irssi SILC client's statusbar. The affected files are
850 irssi/src/silc/core/client_ops.c, silc-expandos.c.
852 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
854 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
855 to SILC_SCHEDULE_[UN]LOCK macros.
857 * Added more error printing to logs in server code. Affected
858 files silcd/server.c and silcd/protocol.c.
860 * Fixed -S option parsing in Irssi SILC Client. Affected file
861 irssi/src/silc/core/silc-core.c.
863 * Added silc_buffer_alloc_size function. Affected file is
864 lib/silcutil/silcbuffer.h.
866 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
868 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
869 constants. Affected files in
870 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
873 * Changed the internal SFTP Memory FS table to const. Affected
874 file lib/silcsftp/sftp_fs_memory.c.
876 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
878 * Fixed the buffer formatting and unformatting routines to
879 check the size of 64 bits types with sizeof(). Affected
880 file is lib/silcutil/silcbuffmt.c.
882 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
884 * Removed 0.6.x backwards support.
886 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
888 * Changed all integer type names:
889 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
890 to avoid collisions with other libraries using same type names
893 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
895 * Added `prefer_ipv6' argument to the functions
896 silc_net_gethostbyname[_async]. If it is TRUE it will return
897 IPv6 address over IPv4. If FALSE IPv4 address is returned
898 even if IPv6 address was found. Affected files
899 lib/silcutil/silcnet.[ch].
901 * Added support silc_net_create_connection[_async] to fallback
902 to IPv4 address if IPv6 address could not be used (like if
903 it doesn't work on a specific system). Affected file in
904 lib/silcutil/unix/silcunixnet.c.
906 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
908 * Added silc_schedule_reinit function to do the enlarging
909 of the max tasks handling capabilities of the scheduler.
910 Affected files lib/silcutil/silcschedule.[ch].
912 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
914 * Added automatic extern "C" { ... } for C++ compilers so the
915 application does not need to define them. Affected file
916 includes/silcincludes.h.
918 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
919 old name went against naming convention. Applications now
920 include "silcclient.h" instead of "clientlibincludes.h".
921 Removed includes/clientlibincludes.h, it is redundant now.
923 * Renamed includes/version.h to silcversion.h.
925 * Added really preliminary support for OS/2 into the util
926 library. Only thread & mutex API is implemented, others
927 are still to be implemented. Created the lib/silcutil/os2/
928 directory. Created also file includes/silcos2.h.
930 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
932 * Added preliminary BeOS support into the util library.
933 Created lib/silcutil/beos/, and implemented all the needed
934 functions to support SILC on BeOS. Created also file
937 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
939 * Added proper initializations to silc's irssi code, so it's
940 now possible to load it as module. Affected files
941 irssi/src/silc/core/silc-core.c,
942 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
944 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
946 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
949 * Fixed the silcdoc document generator to correct generate
950 docs from all kinds of filenames. Affected files are
951 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
953 * ROBOdoc documented lib/silcutil/silcmemory.h.
954 Added also new function silc_memdup.
956 * Removed lib/silcutil/silcbufutil.h and moved those routines
957 to the lib/silcutil/silcbuffer.h.
959 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
961 * Added `user_count' to the SilcChannelEntry which now tells the
962 number of users on the channel. The user count is now saved
963 in normal server of global channels as well. Affected files
964 silcd/server.c, idlist.h, packet_receive.c and command.c.
966 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
967 include file utility functions.
969 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
970 instead of calling directly OS routines.
972 * Fixed NICK change printing in Irssi SILC Client. Fixed
973 KICKED notify printing in Irssi SILC Client. Affected file
974 irssi/src/silc/core/client_ops.c.
976 * Fixed a NICK change bug in client library, to not recreate the
977 client_entry->channels hash table everytime nick is changed.
978 Affected file lib/silcclient/client.c.
980 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
982 * ROBOdoc documented the lib/silcske/silcske.h, and improved
983 the SKE interface a bit.
985 * Fixed padding problem in PKCS#1. The padding was not actually
986 random since the random number generator was used incorrectly.
987 This security bug affects only when encrypting with PKCS#1, and
988 it is not currently used at all in SILC. SILC only use signing
989 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
991 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
993 * Rewrote the notify handling in Irssi SILC client to not call
994 the events as signals. Fixes problems with Perl support.
995 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
997 * Send the auto-nicking NICK command in client library with
998 little timeout after connecting. The affected file is
999 lib/silcclient/client.c.
1001 * Added following new config file settings:
1002 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
1003 key_exchange_timeout, conn_auth_timeout, connections_max,
1006 Implemented all the new config settings handling in the server.
1008 Optimized the use of SKE Mutual flag usage. Use it only
1009 if connection authentication protocol is not based in public
1012 Renamed all SilcServerConfigSection* to SilcServerConfig*
1013 to have a bit shorter names.
1015 Affected files silcd/serverconfig.[ch], server.[ch], and
1018 Sat Feb 16 02:46:43 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1020 * Cleaned up the listening sockets code, preparing for the rehash
1021 support. Affected file is silcd/server.c.
1023 * Fixed some output messages. Affected files are silcd/silcd.c,
1026 Fri Feb 15 19:10:20 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1028 * Create lib/doc/silcrng_intro.html document as introduction
1029 to SILC RNG. ROBOdoc documented lib/silccrypt/silcrng.h.
1031 Fri Feb 15 13:23:03 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1033 * Fixes to the silcd config template. Affected file is
1034 doc/example_silcd.conf.in.
1036 * Removed type casts from silc_calloc(), conforming to the
1037 CodingStyle. Affected file is lib/silcutil/silcconfig.c.
1039 * Removed param_name member from client, server, and router
1040 section structs, now identifying the param directly.
1042 Added CONFIG_FREE_AUTH macro in config file parsing.
1044 Affected files are silcd/serverconfig.[ch].
1046 Fri Feb 15 12:24:08 EET 2002 Timo Sirainen <tss@iki.fi>
1048 * Fixed command line parameter handling. All SILC initialization
1049 is now done in silc_core_init() which also fixes autoconnecting
1052 Affected files irssi/src/silc/core/silc-core.c,
1053 irssi/src/fe-text/silc.c.
1055 Thu Feb 14 22:03:58 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1057 * Added new configuration options and blocks:
1058 keepalive_secs, reconnect_count, reconnect_interval,
1059 reconnect_interval_max, reconnect_keep_trying and
1060 require_reverser_lookup. Added ConnectionParam block, and
1061 implemented the connection parameters when connecting as
1062 initiator and when accepting connections as responder.
1064 Added CONFIG_IS_DOUBLE macro in config file parsing, to check
1065 whether given configuration value has been given already.
1067 Affected files silcd/serverconfig.[c], server.[c].
1069 * Splitted the doc/example_silcd.conf.in. Separated the crypto
1070 algorithm parts and created new file silcalgs.conf, that
1071 is now included from the example_silcd.conf.in.
1073 * Optimized the silc_server_connect_to_router_second to take
1074 the connection configuration object from the SilcServerConnection
1075 object instead of finding it during the connecting phase.
1076 Added the configuration object to SilcServerConnection struct.
1077 Affected files silcd/server_internal.h, server.c.
1079 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1081 * Add the client on channel after it was resolved at the
1082 channel message receiving, and it was not already on the
1083 channel. Affected file lib/silcclient/client_channel.c.
1085 Wed Feb 13 23:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1087 * Fixed the public key authentication to allocate always the

1093 * Unified the serverconfig.[ch]'s helper function interface.
1094 Affected file silcd/serverconfig.[ch].
1096 * Removed doc/example_silc.conf.in since it is redundant.
1097 The make install will now install irssi/silc.conf file.
1099 * Added new Passphrase and Publickey authentication methods to
1100 config file, allowing both public key and passphrase based
1101 authentication to be set at the same time.
1103 Added `prefer_passphrase_auth' setting in config file which
1104 can be used to set to prefer passwd auth if both passwd and
1105 public key is set. If not set, public key is preferred.
1106 This has effect only when being initiator (responder will try
1109 Added support for authentication with passphrase and public key
1110 at the same time. The passphrase is tried first always since
1111 it is faster to check.
1113 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
1115 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1117 * Merged the new SILC Config library, with the server parsing
1118 support. Read the header file silcconfig.h or the toolkit
1119 documentation for the news. Affected files are

1128 Sun Feb 10 18:11:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1130 * The silc_cipher_register, silc_hash_register and
1131 silc_hmac_register now checks if the object to be registered
1132 is registered already. Affected files are
1133 lib/silccrypt/silccipher.c, silchash.c and silchmac.c.
1135 Sun Feb 10 15:48:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1141 * Allow zero length channel messages inside the Channel Message
1142 Payload. Affected file lib/silccore/silcchannel.c.
1144 * Fixed scripts/silcdoc/silcdoc to support all kinds of filenames
1145 as header filenames.
1147 * Removed lib/silcclient/README and created HTML file
1148 lib/silcclient/silcclient_using.html, which is now included
1149 as part of Toolkit documentation.
1151 Thu Feb 7 10:12:25 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1153 * Fixed CUMODE_CHANGE notify handling to change the mode of
1154 correct client. Affected file lib/silcclient/client_notify.c.
1156 * Make silc_rng_alloc fail if it cannot allocate the sha1
1157 hash algorithm. Affected file lib/silccrypt/silcrng.c.
1159 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1161 * Fixed the file transfer's key agreement payload to include
1162 zero port also if the hostname is NULL because it could not
1165 Call file transfer monitor callback now also if error occurs
1166 during key agreement protocol.
1168 Changed the silc_client_file_send interface to return the
1169 SilcClientFileError instead of session id. The session ID
1170 is returned into pointer provided as argument.
1172 Check that the file exists locally before sending the
1173 file transfer request at all.
1175 Affected file lib/silcclient/client_ftp.c, silcapi.h.
1177 * Added SILC_CLIENT_FILE_KEY_AGREEMENT_FAILED file transfer
1178 error than can occur while key agreement protocol. Affected
1179 file lib/silcclient/silcapi.h.

1185 * Fixed SILC_LOG_ERROR to give out Error and not Warning, and
1186 SILC_LOG_WARNING to give out Warning and not Error. Affected
1187 file lib/silcutil/silclog.c.
1189 * Fixed the channel message payload decryption in the function
1190 silc_channel_message_payload_decrypt to not modify the original
1191 buffer before it is verified that the message decrypted
1192 correctly. Otherwise, next time it is called with correct
1193 channel key it won't encrypt since the payload is corrupted.
1194 Affected file lib/silccore/silcchannel.c.
1196 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1198 * Do not constantly resize the window. A fix patch by cras.

1206 Fri Feb 1 22:33:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1208 * Fixed a bug in hash table internal routine for traversing
1209 the table with foreach callback. The current entry may
1210 become invalid in the callback but it was referenced after
1211 the callback returned.
1213 Do not allow auto rehashing of hash table during the
1214 silc_hash_table_foreach operation, for same reasons as it is
1215 not allowed for SilcHashTableList. Affected files are
1216 lib/silcutil/silchashtable.[ch].
1218 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1220 * Defined DLLAPI into silcincludes.h and silcwin32.h for
1221 Win32 DLL. extern's in header files are now declared with
1224 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1226 * Fixed private message handling. It used some old code that
1227 caused the client to crash. Affecte file is
1228 lib/silcclient/client_prvmsg.c.
1230 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1232 * Added function silc_client_add_channel,
1233 silc_client_replace_channel_id, and removed functions
1234 silc_client_new_channel_id and silc_idlist_get_channel_by_id
1235 from client library.
1237 * Added cross reference of the joined channels to the
1238 SilcClientEntry, and changed the SilcChannelEntry's
1239 users list to SilcHashTable. The affected files are
1240 lib/silcclient/idlist.[ch].
1242 * Fixed a bug in hash table tarversing. While the hash table
1243 is traversed with SilcHashTableList the table must not be
1244 rehashed. It is now guaranteed that auto rehashable tables
1245 are not rehashed while tarversing the list. Also defined that
1246 silc_hash_table_rehash must not be called while tarversing
1247 the table. Added function silc_hash_table_list_reset that must
1248 be called after the tarversing is over. The affected files are
1249 lib/silcutil/silchashtable.[ch].
1251 * Changed all hash table traversing to call the new
1252 silc_hash_table_list_reset in server and in client library.
1254 * Added function silc_client_on_channel to return the
1255 SilcChannelUser entry if the specified client entry is joined
1256 on the specified channel. This is exported to application as
1257 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
1259 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1261 * Fixed founder regaining problem with JOIN command on normal
1262 server. The notify for mode change must be sent always and
1263 not only if !cmd->pending. Affected file silcd/command.c.
1265 * Fixed the WHOWAS command's reply sending to support the
1266 lists correctly. Affected file silcd/command.c.
1268 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1270 * When sending JOIN command to router for processing the
1271 sender's old command identifier was not saved back to the
1272 sender's command context, fixed now. The affected file is
1275 * Create the key in JOIN command of the router did not return
1276 the channel key, added check for this. Affected file is
1279 * Fixed a channel ID update bug in JOIN command reply. Do
1280 not directly upgrade the ID but call the function
1281 silc_idlist_replace_channel_id if the ID was changed.
1282 Affected file silcd/command_reply.c.
1284 * Fixed memory leaks from command calling if it would fail.
1285 Affected file silcd/command.c.
1287 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1289 * Applied patches from cras:
1291 Memory leak fixes around libaries, irssi window resize fix,
1292 new silclist.h and silcdlist.h, all extern inline changed to
1295 * Removed dotconf from lib/dotconf, not needed anymore.
1297 * Removed TRQ from lib/trq, not needed anymore.
1299 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
1300 with server connections. Later this will be configurable
1301 in config file after new config file is done. Affected file
1304 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
1306 * Fixed a crash in server related to channel announcements.
1307 Affected file silcd/server.c.
1309 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1311 * Fixed memory leaks in silc_server_create_new_channel*
1312 functions. Affected file silcd/server.c.
1314 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
1315 which ID was changed. This way the router will send the
1316 user list for the channel again, and server won't be in
1317 desync in some rare circumstances. Affected file is
1318 silcd/packet_receive.c.
1320 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1322 * Check for NULL socket pointer in the function
1323 silc_server_packet_send_to_channel_real. Affected file
1324 silcd/packet_send.c.

1327 list. Affected file silcd/packet_receive.c.
1329 Sat Jan 26 23:01:03 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1331 * Fixed some header addition to Toolkit distribution in
1332 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
1334 * Added lib/silcclient/client_ops_example.h as an template
1335 file for application programmers to quickly start using
1336 the SilcClientOperation functions in their application.
1337 Updated the lib/silcclient/README as well to tell about this
1338 nice file made available.
1340 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1342 * Call silc_server_remove_from_channels when removing client
1343 entry when NO_SUCH_CLIENT_ID was received. Affected file
1344 is silcd/command_reply.c.
1346 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1348 * Added server & router operator statistics updating. Affected
1349 file silcd/packet_receive.c and silcd/command.c.
1351 * Fixed the SERVER_SIGNOFF notify handling on normal server
1352 not to save the history information for clients. Same was
1353 fixed earlier in remove_clients_by_server function, but not
1354 here. Affected file silcd/packet_receive.c.
1356 * Raised the default connection-retry count from 4 to 7 in
1357 server. Affected file silcd/server.h.
1359 * Cancel any possible reconnect timeouts when we start the
1360 key exchange. Affected file silcd/server.c.
1362 * Do not reconnect on connection failure when SCONNECT was
1363 given. Affected files silcd/server.[ch].
1365 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1367 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
1369 * Fixed the NICK command to always give the unformatted
1370 nickname to the one giving the NICK command. If unformatted
1371 nickname is cached already it will be formatted and the
1372 local entry will always get the unformatted nickname.
1373 Affected file lib/silcclient/idlist.c.
1375 * Fixed some double frees from client library commands.
1376 Affected file is lib/silcclient/command.c.
1378 * Fixed CUMODE command in server to assure that no one can
1379 change founder's mode than the founder itself, there was a
1380 little bug. Affected file silcd/command.c.
1382 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1384 * Removed the SilcClientCommandDestructor from the client
1385 libary, it is not needed anymore. Affected files are
1386 lib/silcclient/silcapi.h, command[_reply].[ch],
1387 client_notify, idlist.c.
1389 * Fixed GETKEY command to first resolve client, and then
1390 resolve the server only if the client was not found, instead
1391 of resolving both at the same time. Affected file is
1392 lib/silcclient/command.c.
1394 * Added silc_client_start_key_exchange_cb and lookup the
1395 remote hostname and IP address before starting the key
1396 exchange with server. The affected file is
1397 lib/silcclient/client.c.
1399 * The server's public key is now saved using the IP address
1400 of the server and not the servername for the filename.
1401 The hostname public key filename is checked as an fall back
1402 method if the IP address based filename is not found.
1404 Fixed the GETKEY command to save the fetched server key
1405 in correct filename.
1407 Print the remote server's hostname now when new key is
1408 received during connection process. Affected file is
1409 irssi/src/silc/core/client_ops.c.
1411 * Return always our own public key to the client if it asks
1412 for it with GETKEY command. Affected file silcd/command.c.
1414 * Removed the use_auto_addr variable from default config
1415 file since it was in wrong section. Affected file is
1418 * Fixed TOPIC_CHANGE notification to not route it when it
1419 was sent using silc_server_send_notify_to_channel function.
1420 Affected file silcd/command.c.
1422 * Fixed silc_server_send_notify_kicked to send the kicker's
1423 Client ID also, it was missing. Affected files are
1424 silcd/command.c, silcd/packet_send.[ch].
1426 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1428 * Do not save client history information in SERVER_SIGNOFF.
1429 Fixes the bug in normal server that it does not detect
1430 the client becoming valid after the server becomes back
1431 online. Affected file silcd/server_util.c.
1433 * Added `sock_error' field into the SilcSocketConnection
1434 context. When error occurs during socket operation (read
1435 or write) the error is saved. Added also new function
1436 silc_socket_get_error to return human readable socket error
1437 message. Affected files are lib/silcutil/silcsockconn.[ch],
1438 lib/silcutil/unix/silcunixsockconn.c, and
1439 lib/silcutil/win32/silcwin32sockconn.c.
1441 * The server now prints the socket error message in the
1442 signoff for client. Affected file silcd/server.c.
1444 * Fixed the `created' channel information sending from router
1445 to server in JOIN command. Checks now whether the channel
1446 really was created or not and set it according that.
1448 Fixed the JOIN command to use the client entry's current
1449 ID during the joining procedure instead of the one it sent
1450 in the command (it is checked though), since it can change
1451 between the packet processing and command processing, and
1452 would just case unnecessary pain in the client end. Affected
1453 file silcd/command.c.
1455 * Fixed a channel key payload sending to use correct channel
1456 ID when the server was forced to change the channel's ID by
1457 router. Router sent the key payload with the old Channel ID.
1458 Affected file silcd/packet_receive.c.
1460 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1462 * Call silc_server_save_channel_key only if the key payload
1463 was provided in the JOIN command's command reply. Affected
1464 file silcd/command_reply.c.
1466 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1468 * Fixed silc_mp_sizeinbase to return the value correctly with
1469 MPI. Affected file lib/silcmath/mp_mpi.c.
1471 * Fixed the stop_server signal to correctly stop the scheduler
1472 and gracefully stop the server when SIGTERM or SIGINT signals
1473 are received. Affected file silcd/silcd.c.
1475 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1477 * Simple handling of TERM and HUP signals. Also added some log
1478 flushing call around. Affected file is
1481 * Fixed small bugs in silclog.c. Now buffering output will take
1482 effect after 10 seconds since startup: This will ensure that
1483 no important startup messages are lost. Also output redirection
1484 will preserve original format ([Date] [Type] message).
1485 Affected file is lib/silcutil/silclog.c.
1487 * Added two options to the config file, in the logging section:
1488 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1489 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1491 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1493 * Do not print the warning about log files not being initialized
1494 more than once to avoid excess logging. Affected file is
1495 lib/silcutil/silclog.c.
1497 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1498 the SIM copying in make install in Makefile.am.pre.
1500 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1502 * Rewritten silclog APIs. Globally interesting changes follows:
1503 silc_log_set_files() changed to silc_log_set_file().
1504 silc_log_set_callbacks() changed to silc_log_set_callback().
1505 ROBOdoc documented silclog header file.
1506 SilcLogCb now returns bool to wether inihibit the default
1507 handler or not (to keep the old behaviour return always TRUE).
1508 The new APIs should also fix the problem of the
1509 silcd_error.log file that was written in the current directory.
1512 Log files streams will remain opened after silc_log_set_file()
1513 call, means less CPU usage notably on high traffic servers.
1514 File streams are now full buffered, and flushed to the disk
1515 every 5 minutes, lesses HD activity and CPU usage.
1516 Messages can be redirected, allowing admins to configure
1517 one single logfile for all server messages.
1518 the silc_log_quick global variable to activate fast-logging.
1519 Affected files lib/silcutil/silclog.[ch]
1521 * Changed some code to conform new silclog APIs. Affected
1522 files are doc/example_silcd.conf.in, silcd/server.c
1523 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1526 * Fixed a memory leak that could occur in some situations.
1527 Affected file silcd/serverconfig.c.
1529 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1531 * Added the silc_client_del_client to remove the client from
1532 all channels as well. Affected file lib/silcclient/idlist.c.
1534 * Fixed the client library to correctly remove the client
1535 from all channels when the client entry is being destroyed.
1536 Affected file lib/silcclient/client_notify.c, command.c.
1538 * Added auto-nicking support to the client library. If the
1539 applicatio now sets client->nickname it will be sent to the
1540 server after connecting by the library. This way for example
1541 SILCNICK (or IRCNICK) environment variables will have effect
1542 and always change the nickname automatically to whatever
1543 it is wanted. Affected file lib/silcclient/client.[ch].
1545 * Renamed silc_server_command_bad_chars to the
1546 silc_server_name_bad_chars and moved it to the
1547 silcd/server_util.[ch]. Added also new function
1548 silc_server_name_modify_bad to return nickname that
1549 includes bad characters as new nickname without those
1550 bad characters. This check and modify is now used in
1551 silc_server_new_client when the username is initially set
1552 as nickname, so it must be checked to be valid nickname.
1553 Affected file silcd/packet_receive.c.
1555 * The nickname length is now taken from the packet for real
1556 and not trusted to strlen() since it clearly can return
1557 wrong length for nickname including bad characters. This
1558 also applies to channel names. Affected file silcd/command.c.
1560 * Removed the lib/silcsilm/modules directory. Modules are now
1561 compiled into the lib/silcsim. Fixed the copying of the
1562 modules to follow symbolic links in Makefile.am.pre.
1564 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1566 * Fixed silc_string_regexify list creation. Fixes bugs with
1567 BAN and INVITE commands in server. The affected file is
1568 lib/silcutil/unix/silcunixutil.c.
1570 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1572 * Removed the command destructor entirely from the server's
1573 command and command reply routines. It is not needed, and
1574 its usage was buggy and caused crashes. Affected files are
1575 silcd/command[_reply].[ch].
1577 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1579 * Cancel protocol and NULL sock->protocol if timeout
1580 occurred during protocol. Affected file silcd/server.c.
1582 * Cancel protocol timeouts always before calling the final
1583 callback, to assure that after final callback is called
1584 no other state will be called for the protocol anymore.
1585 Affected file silcd/protocol.c.
1587 * Print error log if incoming connection configuration could
1588 not be found. Affected file silcd/server.c.
1590 * Fixed JOIN command to correctly save the founder mode
1591 to the client on normal SILC server, when the channel
1592 was created by the router. Affected file silcd/command.c.
1594 * Fixed LIST command (hopefully) to send correct reply
1595 packets. Affected file silcd/command.c.
1597 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1599 * The silc_packet_receive_process now returns FALSE if the
1600 read data was invalid packet, and TRUE if it was ok.
1602 The server now checks that if unauthenticated connection
1603 sends data and its processing fails the server will close
1604 the connection since it could be a malicious flooder.
1606 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1608 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1610 * Make sure the warning about error opening a log file is
1611 printed only once and not everytime it fails (produces
1612 too much useless log). Affected file lib/silcutil/silclog.c.
1614 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1616 * Made the silc_server_daemonise() function more readable.
1617 Affected file silcd/server.c.
1619 * Pid file is now optional, the user may comment it out from
1620 the config file. Removed define SILC_SERVER_PID_FILE, we
1621 don't need a default any longer. Affected file
1622 configure.in.pre, lib/Makefile.am.pre.
1624 * Make some use of the pid file. The server now dies at startup
1625 if it detects a valid pid file on his path. The server would
1626 die anyway in this circumstance, because of the bind() failure.
1627 Affected file silcd/silcd.c.
1629 * No longer compiling lib/dotconf.
1631 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1633 * Fixed JOIN command parsing not to crash. Affected file
1634 lib/silcclient/command.c.
1636 * Fied the NICK_CHANGE notify to add the new client entry
1637 even it is resolved. This removes an <[unknown]> nick
1638 thingy bug in the client. Affected file is
1639 lib/silcclient/client_notify.c.
1641 * Do not try to allocate 0 bytes (efence does not like it)
1642 in lib/silccore/silccomand.c when encoding payload.
1644 * Do not take IRCNICK as nickname in Irssi SILC client since
1645 it is not possible to set nickname before hand connecting
1646 the server (TODO has an entry about adding auto-nicking
1649 * Changed the silc_server_command_pending to check whether
1650 there already exists an pending entry with the specified
1651 command, command identifier and pending callback. This is
1652 to fix IDENTIFY and WHOIS related crashes that may register
1653 multiple pending commands with same identifier. Affected
1654 file silcd/command.c.
1656 * Fixed the server to reconnect to the router even if it
1657 was already reconnecting and EOF was received. This to
1658 fix a possibility that the server wouldn't ever try to
1659 auto-reconnect to the router. Affected file silcd/server.c.
1661 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1663 * Fixed the server's password authentication to use the
1664 length of the locally saved password, and not the one
1665 sent in the packet. Affected file silcd/protocol.c.
1667 * Fixed same password authentication problem in the
1668 Authentication Payload handling routines in
1669 lib/silccore/silcauth.c.
1671 * Yet another password authentication problem fixed with
1672 channel password handling in silcd/command.c.
1674 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1676 * If first character of string in silc_parse_userfqdn is '@'
1677 then do not parse it. Affected file is
1678 lib/silcutil/silcutil.c.
1680 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1682 * Fixed minor bug in IDENTIFY command reply sending, which
1683 caused various weird problems during JOIN when it was
1684 resolving names for users. Affected file silcd/command.c.
1686 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1688 * Fixed the IDENTIFY command reply sending to chech better valid
1689 clients. It was possible to send incomplete list of replies.
1690 Affected file silcd/command.c.
1692 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1694 * Added silc_client_command[s]_[un]register functions now to
1695 dynamically register the commands in client library. Removed
1696 the static table of commands. This allows the client library
1697 to call commands without causing the application to know about
1698 what commands library has called.
1700 Removed the INFO command reply kludge to detect when the command
1701 was called by library. Now library use its own command reply
1702 function for INFO command.
1704 Added function silc_client_command_call to call a command.
1705 Application can use it to call command, not access the structure
1708 Now all commands that are sent by the client library (not
1709 explicitly sent by application) use own command reply functions.
1711 Affected files around lib/silcclient/ and in
1712 irssi/src/silc/core/.
1714 * Fixed the WHOIS command reply sending to chech better valid
1715 clients. It was possible to send incomplete list of replies.
1717 Fixed the WHOIS and IDENTIFY to send the request to router
1718 if normal server did not do it and did not find any results.
1720 Affected file silcd/command.c.
1722 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1724 * Moved the internal data from SilcClient context into its
1725 own file, not accesible to application. Affected files
1726 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1727 and other files in client library.
1729 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1731 * Added doc/examples installation target in Makefile.am.pre.
1734 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1736 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1737 commands the found client entry will be removed from the
1738 cache, after notifying application about the error. Affected
1739 file lib/silcclient/command_reply.c.
1741 * Changed the /MSG to check for exact nickname user gave, and
1742 not let `nick' match `nick@host' if it is only one found. Now,
1743 user must type the exact nickname (like nick@host2) even if
1744 there are no more than one same nicks found. This is to avoid
1745 a possibility of sending nickname to wrong nickname since
1746 `nick' could match `nick@host'. Affected file is
1747 irssi/src/core/silc-servers.c.
1749 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1751 * Do not print "you are now server operator" or similar when
1752 giving /away command. Affected files are
1753 irssi/src/silc/core/client_ops.c, silc-servers.h.
1755 * Made the silc_server_command_pending_error_check to send
1756 the same command reply payload it received back to the
1757 original sender of the command. This way all arguments
1758 that was received by the server will be received by the
1759 client too. Affected file silcd/command.c.
1761 * Added the silc_idcache_add to return the created cache entry
1762 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1764 * Add global clients to expire if they are not on any channel.
1765 This is because normal server will never know if they signoff
1766 if they are not on any channel. The cache expiry will take
1767 case of these entries. This is done by normal servers only.
1768 The affected files are silcd/command_reply.c,
1769 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1771 * If server receives invalid ID notification for WHOIS or
1772 IDENTIFY and the ID exists in the lists, it is removed.
1773 Affected file silcd/command_reply.c.
1775 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1776 in client then client entry that it matches is searched and
1777 the nickname is printed on the screen for user. Affected
1778 file irssi/src/silc/core/client_ops.c.
1780 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1782 * Use cache entry expire time in the LIST command reply to
1783 purge old entries from the cache after the LIST command
1784 reply has been received. This way we don't have non-existent
1785 entries in the cache for too long. Affected file is
1786 silcd/command_reply.c.
1788 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1790 * If we are normal server, and we've not resolved client info
1791 in WHOIS or IDENTIFY from router, and it is global client,
1792 we'll check whether it is on some channel. If it is not
1793 then we cannot be sure about its validity and will resolve it
1794 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1795 file silcd/command.c.
1797 * Search channel by name (if possible) rather than by ID
1798 in IDENTIFY command's command reply. Affected file is
1799 silcd/command_reply.c.
1801 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1803 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1804 Updated specs and implemented it. Affected file silcd/command.c,
1805 silcd/packet_send.c and silcd/packet_receive.c.
1807 * Implemented the <founder auth> payload handling in the JOIN
1808 command. If provided all conditions for channel joining
1809 except requirement to provide correct passphrase can be
1810 overrided by the channel founder. Updated the protocol specs.
1811 Affected file silcd/command.c.
1813 Added support for founder auth in JOIN command in client
1814 library. Fixed the parsing of the JOIN command now to support
1815 all options as they should be. The affected file is
1816 lib/silcclient/command.c.
1818 * Optimized the WHOIS and IDENTIFY commands to send the request
1819 to router only if it includes nicknames or other names. If
1820 they include only IDs then check the local cache first before
1821 routing. Affected file is silcd/command.c.
1823 * Added channels topic announcements. Affected file is
1824 silcd/packet_receive.c and silcd/server.c.
1826 * Fixed the silc_server_send_notify_topic_set to really destine
1827 the packet to channel. Affected file silcd/packet_send.c.
1829 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1830 library. Affected file lib/silcclient/client_notify.c.
1832 * Added UMODE announcements. Affected file silcd/server.c.
1834 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1836 * Memory leak fixes in:
1838 lib/silcutil/silcsockconn.c
1839 lib/silcske/silcske.c
1840 lib/silcske/groups.c
1842 lib/silccrypt/silcpkcs.c
1843 lib/silccore/silccommand.c
1844 lib/silccore/silcidcache.c
1849 * ROBOdoc documented the lib/silcske/groups.h file and a
1850 bit changed the interface for better.
1852 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1854 * Update the client entry context in the ID cache after
1855 nick change. Affected file lib/silcclient/command.c.
1856 Fixes the CUMODE command when regaining founder privileges,
1857 and a little WHOIS problem.
1859 * Fixed silc_net_gethostbyname to correctly call the
1860 inet_ntop. Affected file lib/silcutil/silcnet.c.
1862 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1864 * Added IPv6 support checking to the configure.in.pre, added
1865 also --enable-ipv6 option to override the check. Affected
1866 file configure.in.pre.
1868 * The silc_thread_create now calls the start function
1869 directly if threads support is not compiled in. Removes
1870 ugly #ifdef's from generic code. Affected files are
1871 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1873 * Added silc_net_gethostby[name/addr]_async to asynchronously
1874 resolve. Affected files are lib/silcutil/silcnet.[ch].
1876 * Added support for rendering IPv6 based server, client and
1877 channel IDs. Affected file lib/silcutil/silcutil.c.
1879 * Added support for creating IPv6 based server IDs. Affected
1880 file is silcd/serverid.c.
1882 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1884 * Added silc_net_gethostby[addr/name] into the
1885 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1886 routines. Added silc_net_is_ip[4/6]. Affected file is
1887 lib/silcutil/unix/silcunixnet.c. All routines that take
1888 address as argument now supports both IPv4 and IPv6 addresses.
1890 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1892 * Fixed LIST command reply sending in server. Affected file
1895 * Server now sends the kicker's client ID in the KICK notify
1896 to the kicked client. Affected file silcd/command.c.
1898 * The client library now parses the kickers client ID and
1899 UI displays it. Affected files lib/silcclient/client_notify.c
1900 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1902 * Made all payload parsing function prototypes consistent.
1903 They all take now const unsigned char * and uint32 pair as
1904 the payload data instead of SilcBuffer. Changes all around
1905 the source tree. Other unsigned char* -> const unsigned char*
1906 changes around the tree as well.
1908 * Optimized SFTP client and server packet sending not to
1909 allocate new buffer for each packet but to recycle the
1910 first allocated buffer. Affected files are
1911 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1913 * Optimized the SFTP client to use SilcList instead of
1914 SilcDList for requests, because it is faster. Affected file
1915 is lib/silcsftp/sftp_client.c.
1917 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1918 into lib/silccore/silcid.[ch].
1920 Renamed silcpayload.[ch] into silcargument.[ch].
1922 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1924 * If client entry is deleted with active key agreement
1925 session, abort the session.
1927 The silc_client_abort_key_agreement now calls the completion
1928 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1930 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1933 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1935 * Don't use __restrict in older GCC's. Affected file is
1936 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1938 * silc_net_localhost now attempts to reverse lookup the
1939 IP/hostname. Affected file lib/silcutil/silcnet.c.
1941 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1942 command. It can be used to gain founder privileges at
1943 the same time when joining the channel.
1945 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1946 kicker's client ID as well. Updated protocol specs.
1948 Defined that the server must send SILC_COMMAND_IDENTIFY
1949 command reply with error status to client who sent
1950 private message with invalid client ID.
1952 Updated the protocol specification.
1954 * Added silc_server_send_command_reply to send any
1955 command reply. Affected file silcd/packet_send.[ch].
1957 * Added silc_id_payload_encode_data to encode ID payload
1958 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1960 * The server now send IDENTIFY command reply with error
1961 status if client ID in private message is invalid. Affected
1962 file silcd/packet_receive.c.
1964 * Save the server key file with server's IP address in
1965 the filename instead of hostname. The affected file is
1966 irssi/src/silc/core/client_ops.c.
1968 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1970 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1973 * Added libtool support for compiling shared objects in
1974 lib/silcsim. Affected file configure.in.pre and
1975 lib/silcsim/Makefile.am. Original patch by cras.
1977 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1979 * Pid file configuration, and server's config file fixes
1980 patch by toma. Updated CREDITS file.
1982 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1984 * Fixed silc_client_channel_message to not try to decrypt
1985 the message twice if it resolved the destination client
1986 information. This could cause of dropping one channel
1987 message. Affected file lib/silcclient/client_channel.c.
1989 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1991 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1992 lib/silcclient/client.c. This function is used when the SILC
1993 Client is run under some other scheduler, or event loop or
1994 main loop. On GUI applications, for example this may be
1995 desired to used to run the client under the GUI application's
1996 main loop. Typically the GUI application would register an
1997 idle task that calls this function multiple times in a second
1998 to quickly process the SILC specific data.
2000 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
2002 * Fixed silc_server_drop() for dropping the supplementary
2003 groups as well, this could cause a security hole on some
2006 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2008 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by

2012 to run server on foreground. A patch by debolaz.
2013 Affected files silcd/server.c, silcd/silcd.c.
2015 * Fixed MOTD to return the MOTD file server name. Affected
2016 file silcd/command.c.
2018 * Added INFO command reply handling to the Irssi SILC Client.
2019 Affected file irssi/src/silc/core/client_ops.c.
2021 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2023 * Fixed the silc_idcache_list_* routines to really support
2024 the dynamic list. Fixes a crash. Affected file is
2025 lib/silccore/silcidcache.c.
2027 * Fixed the LIST command reply to really call LIST command's
2028 pending callbacks. Affected file silcd/command_reply.c.
2030 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2032 * Update conn->local_entry->nickname after giving NICK
2033 command. Affected file lib/silcclient/command.c.
2035 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
2037 * Added the [pid] option to the silcd configuration file
2039 Affected files: serverconfig.[ch] and silcd.c
2041 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2043 * Save fingerprint in WHOIS command reply in server.
2044 Affected file silcd/command_reply.c.
2046 * Fixed NICK commands pending callback registration.
2047 Affected file lib/silcclient/command.c.
2049 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2051 * Use ++server->cmd_ident when sending commands in server,
2052 instead of random number. Affected file silcd/command.c.
2054 * Fixed GETKEY command reply to call actually GETKEY pending
2055 command callbacks. Affected file silcd/command_reply.c.
2057 * A bit stricter check for nicknames. Check for same nickname
2058 in NICK command also. Affected file silcd/command.c.
2060 * Do not call INFO command everytime client ID changes, only
2061 during first connecting. Affected file lib/silcclient/client.c.
2063 * Set the new nickname only after successful command reply for
2064 NICK command is returned by server. Affected file
2065 lib/silcclient/command.c.
2067 * Remove nicknames from nicklist during server_signoff notify.
2068 Should fix /NAMES bit more. The affected file is
2069 irssi/src/silc/core/silc-channels.c.
2071 * Added `fingerprint' field to the SilcIDListData in the
2072 silcd/idlist.h to hold the fingerprint of the client's
2075 Send the fingerprint of the client's public key in WHOIS
2078 Affected files silcd/command.c, and silcd/idlist.[ch].
2080 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
2081 create fingerprint from given data.
2083 * Show the fingerprint of the client's public key in WHOIS.
2084 Affected files irssi/src/module-formats.[ch] and
2085 irssi/src/silc/core/client_ops.c.
2087 * Format the multiple same nicknames also during JOIN and
2088 NICK_CHANGE notifys. Affected file is
2089 lib/silcclient/client_notify.c.
2091 * Do not print error on screen for invalid private message
2092 payload since it can come if someone is sending private
2093 messages with wrong key. Affected file
2094 lib/silccore/silcprivate.c.
2096 * Fixed multiple concurrent /PING crash. Affected file
2097 lib/silcclient/command.c.
2099 * Changed the wrong ID encoding. All IP addresses must be
2100 in MSB first order in encoded format. They were encoded
2101 wrong and was in LSB format. Affected files are
2102 silcd/serverid.c, lib/silcutil/silcutil.c.
2104 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
2106 * Call the `connect' client operation through the scheduler
2107 in case of error. Affected file lib/silcclient/client.c.
2109 * Call the `failure' client operation even if the error
2110 occurred locally during a protocol. Affected file is
2111 lib/silcclient/protocol.c.
2113 * Added support of sending LIST command to router from normal
2114 server. This way normal server can get list of all channels
2115 in the network too. Fixed the channel list sending in the
2116 server too. Affected files are silcd/command.c, and
2117 silcd/command_reply.[ch].
2119 * Added silc_server_update_channels_by_server and
2120 silc_server_remove_channels_by_server. They are used during
2121 disconnection of primary router and in backup router protocol.
2122 Affected file silcd/server_util.[ch], silcd/server.c and
2123 silcd/server_backup.c.
2125 * Fixed channel adding to global list in IDENTIFY command
2126 reply in server. Affected file silcd/command_reply.c.
2128 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2130 * If the incoming packet type is REKEY or REKEY_DONE process
2131 that packet always synchronously. Fixes yet another MAC
2132 failed error on slow (dialup) connections. Affected file
2133 lib/silcclient/client.c and silcd/server.c.
2135 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2137 * Call check_version SKE callback for initiator too. Affected
2138 file lib/silcske/silcske.c.
2140 * Implemented fix for security hole found in the SKE that was
2141 fixed in the specification few days back; the initiator's
2142 public key is now added to the HASH value computation.
2143 Added backwards support for the old way of doing it too, for
2144 old clients and old servers. Affected file is
2145 lib/silcske/silcske.c.
2147 * Enabled mutual authentication by default in SKE. If initiator
2148 is not providing mutual authentication the responder will
2149 force it. This will provide the proof of posession of the
2150 private key for responder. The affected files are
2151 lib/silcclient/protocol.c and silcd/protocol.c.
2153 * Do not cache anymore the server's public key during SKE.
2154 We do mutual authentication so the proof of posession of
2155 private key is done, and if the server is authenticated in
2156 conn auth protocol with public key we must have the public
2157 key already. Affected file silcd/protocol.c.
2159 * Added new global debug variable: silc_debug_hexdump. If
2160 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
2161 file lib/silcutil/silclog.[ch].
2163 * Fixed compilation warning due to char * -> const char *.
2164 Affected files lib/silcutil/silcnet.h, and
2165 lib/silccore/silcauth.[ch].
2167 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2169 * Fixed CMODE command when new channel key was created. If
2170 the creation failed the old key was removed. Next time giving
2171 same command would crash the server since the old key was
2172 freed already. Affected file silcd/command.c.
2174 * Fixed the silc_server_announce_get_channels to not crash
2175 on reconnect. Affected file silcd/server.c.
2177 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2179 * Added silc_log_set_debug_string function to set a regex
2180 string to match for debug output. Only the function names,
2181 or filenames matching the given debug string is actually
2182 printed. This way it is possible to filter out those debug
2183 strings that user is not interested in.
2185 Fixed a bug in silc_string_regexify.
2187 Affected files lib/silcutil/silclog.[ch], and
2188 lib/silcutil/unix/silcunixutil.c.
2190 * Changed the -d options in both server and Irssi SILC client
2191 to take the debug string as argument. Affected files
2192 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
2194 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2196 * Added silc_hash_babbleprint to create a Bubble Babble
2197 Encoded fingerprint. The encoding is developed by Antti
2198 Huima (draft-huima-babble-01.txt), and it creates human
2199 readable strings out of binary data. Affected file
2200 lib/silccrypt/silchash.[ch].
2202 * Print the babble print now in addition of fingerprint as well
2203 in Irssi SILC client. Affected files are
2204 irssi/src/fe-common/silc/module-formats.[ch],
2205 irssi/src/fe-common/silc/core/client_ops.c.
2207 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2209 * Fixed a security problem found in SKE. The initiator's
2210 public key too is now added to the HASH hash value creation
2211 which is signed by the responder to create the SIGN value.
2212 This will prevent anyone in the middle to lie to the responder
2213 about the initiator's public key. If this is done now, the
2214 man in the middle will get caught. Updated the protocol
2217 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2219 * Better installation directory handling. Configure module
2220 paths and other paths automatically to example_silc* files
2221 in doc/. A patch by toma.
2223 * Fixed compiler warning from MPI library, and from SILC RNG.
2226 * Added SILC_SERVER_PID_FILE to define the pid file for server.
2227 It can be configured with ./configure. A patch by toma.
2229 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2231 * Find correct make to use in prepare-clean. A patch by
2232 toma. Affected file prepare-clean.
2234 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
2236 * Added irssi variables use_auto_addr, auto_bind_ip,
2237 auto_bind_port and auto_public_ip.
2239 * Changed the interface for silc_client_send_key_agreement
2240 in lib/silcclient/silcapi.h
2244 irssi/src/silc/core/silc-core.c
2246 lib/silcclient/silcapi.h
2247 irssi/src/silc/core/silc-channels.c
2248 lib/silcclient/client_keyagr.c
2251 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
2253 * Added silc_pkcs_public_key_compare to compare two
2254 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
2256 * Check that the client who set the founder mode on the
2257 channel is the same client that is giving the founder
2258 mode to itself. It is done by comparing the saved public
2259 key (it is saved even in the authentication is passphrase).
2260 Affected file silcd/command.c.
2262 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2264 * Do not process packet for disconnected socket connection.
2265 Affected file lib/silccore/silcpacket.c.
2267 * Process the DISCONNECT packet through scheduler in the
2268 client library. Affected file lib/silcclient/client.c.
2270 * Fixed the silc_client_packet_parse to not to increase
2271 the packet sequence number if the conn->sock and the
2272 current socket connection is not same. This can happen
2273 for example during key agreement when the conn includes
2274 multiple socket connections (listeners). Affected file
2275 lib/silcclient/client.c.
2277 * The sender of the file transfer request now provides also
2278 the pointer (listener) for the key exchange protocol. If
2279 the listener cannot be created then it sends empty key
2280 agreement and lets the receiver provide the listener.
2282 Added `local_ip' and `local_port' arguments to the
2283 silc_client_file_send. If they are provided they are used,
2284 if not then it will attempt to find local IP address, if
2285 not found or bind fails then the remote client will provide
2288 Affected files are lib/silcclient/client_ftp.c and
2289 lib/silcclient/silcapi.h.
2291 * Extended the FILE SEND command to support defining the
2292 local IP and port for key exchange listener. They are
2293 optional. Affected file irssi/src/silc/core/silc-servers.c.
2295 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2297 * Defined to WHOIS command reply the sending of fingerprint
2298 of the client's public key (if the proof of posession of the
2299 corresponding private key is verified by the server).
2300 Updated to the protocol specification.
2302 * Added support of receiving the client's public key's
2303 fingerprint in command reply in client library. Affected
2304 file is lib/silcclient/command_reply.c, and
2305 lib/silcclient/idlist.[ch].
2307 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2309 * Do not send over 128 chars long nickname to the server
2310 in NICK command. Affected file lib/silcclient/command.c.
2312 * Do not send over 256 chars long channel names to the server
2313 in JOIN command. Affected file lib/silcclient/command.c.
2315 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2317 * Assure that silc_server_close_connection cannot be called
2318 twice for same socket context. Affected file is
2321 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2323 * Send error message to application if opening file for
2324 writing during file transfer fails. Affected file is
2325 lib/silcclient/client_ftp.c.
2327 Remove all file transfer sessions for a client that we're
2328 removing from ID cache.
2330 Affected file is lib/silcclient/client_ftp.c.
2332 * Fixed silc_net_addr2bin to return correct address. Affected
2333 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2335 * Fixed file transfer session removing on signoff notify.
2336 Affected file irssi/src/silc/core/silc-servers.c.
2338 * Added the SilcClientFileError to be returned in the monitor
2339 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
2340 Affected file lib/silcclient/silcapi.h.
2342 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Fixed a crash in silc_client_ftp_free_sessions and
2345 silc_client_ftp_session_free_client. Affected file
2346 lib/silcclient/client_ftp.c.
2348 * Added `disabled' field in the SilcChannelEntry in the server
2349 to indicate if the server entry is disabled. Affected file
2350 silcd/idlist.h, silcd/command[_reply].c.
2352 * SILC server adds now /var/run/silcd.pid everytime it is
2353 started. Affected file silcd/silcd.c.
2355 * Added silc_server_packet_send_clients to send a packet to
2356 the provided table of client entries. Affected file
2357 silcd/packet_send.[ch].
2359 * Fixed a crash in client resolving in client_prvmsg.c in
2360 client library. Affected file lib/silcclient/client_prvmsg.c.
2362 * Do not actually remove the client directly from ID cache
2363 during SERVER_SIGNOFF, but invalidate it. This way we
2364 preserve the WHOWAS info for the client. Affected file
2365 silcd/server_util.c.
2367 * Fixed SERVER_SIGNOFF notify handling in the server. The
2368 server is now able to process incoming SERVER_SIGNOFF notify
2369 for a server that it doesn't even know about. It will remove
2370 the clients provided in the notify. Affected file
2371 silcd/packet_receive.c.
2373 * Check for partial packet in data queue after every packet that
2374 was found from the queue. Return and wait for more data if
2375 there is partial data in queue. Affected file is
2376 lib/silccore/silcpacket.c.
2378 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2380 * Added SilcClietFileError enum to indicate error in
2381 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2382 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2383 Affected files lib/silcclient/silcapi.h and
2384 lib/silcclient/client_ftp.c.
2386 * Check that newsize in silc_buffer_realloc is larger than
2387 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2389 * Added better monitor of file transfers. It now monitors
2390 key agreement protocol during the file transfer too. Added
2391 error reporting too. Affected files
2392 irssi/src/silc/core/silc-servers.c,
2393 irssi/src/fe-common/silc/module-formats.[ch].
2395 * Wrote a help file for FILE command.
2397 * Added silc_rng_global_get_byte_fast to get not-so-secure
2398 random data as fast as possible. Random data is read from
2399 /dev/urandom if available and from the SILC RNG if not
2400 available. It is used in padding generation. Affected file
2401 lib/silccrypt/silcrng.[ch].
2403 * All packets in client library are now processed synchronously.
2404 Optimized packet processing a lot. Affected file
2405 lib/silcclient/client.c.
2407 * All server connection packets are processing synchronously
2408 now in server, to optimize packet processing. Affected file
2411 * Include files are installed now only in Toolkit distribution
2412 if make install is given. Affected files: all Makefile.am's.
2414 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2416 * Assure that silc_client_notify_by_server_resolve does not
2417 resolve the client information multiple times. If it cannot
2418 be found by the first it cannot be found at all. Affected
2419 file lib/silcclient/client_notify.c.
2421 * Fixed WHOWAS command reply calling. Affected file
2422 lib/silcclient/command_reply.c.
2424 * Removed all references to silc_idlist_get_client from the
2425 Irssi SILC client since that call is internal call used by
2426 the library. The Irssi SILC client will use now client
2427 retrieval functions found in silcapi.h.
2429 * Fixed a bug in resolving nickname info before sending
2430 private message. It used freed memory. Affected file
2431 irssi/src/silc/core/silc-servers.c.
2433 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2435 * Assure my_channels statistics cannot go negative in server.
2436 Affected files silcd/server.c, silcd/server_util.c.
2438 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2440 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
2442 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2444 * Win32 Toolkit changes. Affected files
2445 win32/silc.dsw, win32/libsilc/libsilc.def,
2446 win32/libsilcclient/libsilc.def,
2447 lib/silcutil/silcutil.c, and
2448 lib/sftp/sftp_fs_memory.c.
2450 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2452 * Added silc_net_localip to return local host's IP address.
2453 Affected file lib/silcutil/silcnet.[ch].
2455 * If key exchange or rekey protocol is active for a connection
2456 parse all packets syncronously since there might be packets
2457 in packet queue that we are not able to process without first
2458 processing packets before them. Affected file silcd/server,
2459 lib/silcclient/client.c.
2461 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2462 whether library should continue processing the packet.
2463 Affected file lib/silccore/silcpacket.h.
2465 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2466 SilcSFTPMonitorData to SFTP server to monitor various
2467 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
2468 lib/silcsftp/sftp_server.c.
2470 * Added silc_file_size to return file size. Affected file
2471 lib/silcutil/silcutil.[ch].
2473 * Implemented the file transfer support for the client library.
2474 Added preliminary support for simple client to client one-file
2475 transmission. Affected file lib/silcclient/client_ftp.c,
2476 lib/silccilent/client.[ch].
2478 * Added new local command FILE to the Irssi SILC Client.
2479 It is used to perform the file transfer. It has subcommands
2480 SEND, RECEIVE, SHOW and CLOSE. Affected files
2481 irssi/src/silc/core/client_ops.c,
2482 irssi/src/silc/core/silc-server.[ch].
2484 Mon Oct 22 12:50:08 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2486 * Relay the SILC_PACKET_FTP in the server. Affected files
2487 silcd/server.c and silcd/packet_receive.c.
2489 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2491 * Renamed silc_file_read and silc_file_write to functions
2492 silc_file_readfile and silc_file_writefile. Added function
2493 silc_file_open and silc_file_close. Affected files
2494 lib/silcutil/silcutil.[ch].
2496 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2498 * Resolve the client info when received private message or
2499 channel message for a client which nickname we don't know.
2500 Affected files lib/silcclient/client_prvmsg.c and
2501 lib/silcclient/client_channel.c.
2503 * Do not crash in /KEY if client is not connected. Affected
2504 file irssi/src/silc/core/silc-channels.c.
2506 * Added SilcClientStatus field to the SilcClientEntry in the
2507 lib/silcclient/idlist.h.
2509 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2510 is incomplete and is being resolved, it won't be resolved
2513 Make sure also that USERS command reply does not resolve
2514 twice information. Affected file is
2515 lib/silcclient/command_reply.c.
2517 Make sure that silc_client_get_clients_by_list does not
2518 resolve twice same information.
2520 * Check for valid client->id in the silc_server_free_client_data.
2521 Affected file silcd/server.c.
2523 * Fixed /GETKEY nick@server not to crash if the server entry
2524 is not found. Affected file lib/silcclient/command.c.
2526 * Fixed the silc_server_check_cmode_rights to check the
2527 requested modes correctly. Affected file silcd/command.c.
2529 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2531 * Better checks for non-printable chars in nick added.
2532 Affected file silcd/command.c.
2534 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2536 * Call the silc_server_udpate_servers_by_server in the
2537 primary router that comes back online in the backup resuming
2538 protocol. Otherwise it routes packets wrong. Affected file
2539 silcd/server_util.[ch], silcd/server_backup.c.
2541 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2543 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2544 lib/silcutil/silcbuffmt.[ch].
2546 * Redefined the SILC packet header to include the padding
2547 length. Affected file lib/silccore/silcpacket.[ch].
2549 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2550 length for maximum padding up to 128 bytes). Affected
2551 file lib/silccore/silcpacket.h.
2553 * Removed all backwards support for old 0.5.x MAC thingies.
2554 The SILC packet header change makes it impossible to be
2555 backwards compatible.
2557 * Send the ENDING packet with timeout in the backup resuming
2558 protocol. This is to assure that all routers has connected
2559 to the primary router. Affected file silcd/server_backup.c.
2561 * Changed the RNG to take the first IV from random data. It
2562 used to take it from zero actually. Changed the RNG also
2563 to use /dev/urandom during session. /dev/random is used
2564 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2566 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2568 * Changed the SILC packet header to have the first two bytes
2569 (the packet length) encrypted. Affected files aroung the
2570 code tree, lib/silccore/silcpacket.[ch]. Removed the
2571 SilcPacketCheckDecrypt callback. It is not needed anymore
2572 since the silc_packet_receive_process will determine now
2573 whether the packet is normal or special.
2575 * Implemented the unidirectional MAC keys. Affected files
2576 lib/silcske/silcske.c, silcd/protocol.c and
2577 lib/silcclient/protocol.c.
2579 * Implemented the packet sequence number to the MAC computation.
2580 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2581 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2582 lib/silcclient/protocol.c.
2584 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2586 * Allow backup router to announce servers. All servers
2587 announced by backup router are added to the global list
2588 automatically. Update hte server's socket to our primary
2589 router also when backup router announces a server.
2590 Affected file silcd/packet_receive.c.
2592 * Do not update the client->router in the function
2593 silc_server_udpate_clients_by_server if the client is on
2594 global list. We might fail to find any specific server
2595 for locally connected clients and local cell clients. They
2596 should still use the `from' and not `to' as client->router.
2597 This fixes backup router resuming protocol. Affected file
2598 silcd/server_util.c.
2600 * Decrease channel statistics count only if the channel
2601 deletion worked. Affected files are silcd/server.c and
2602 silcd/server_util.c.
2604 * Added silc_server_update_servers_by_server to update origin
2605 of all server entries. Used during backup router protocol.
2606 Affected files silcd/server_util.[ch], silcd/server.c. and
2607 silcd/backup_router.c.
2609 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2610 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2611 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2612 lib/silccrypt/silchmac.c.
2614 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2616 * Assure that router cannot reroute the same channel message
2617 to the sender. Affected file silcd/packet_receive.c.
2619 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2621 * Made better checks that the channel message is not sent
2622 to the router it came from. Affected file is
2623 silcd/packet_send.c. Fixed memory leak too.
2625 * Announce informations for incoming router connection, but
2626 only after checking if it is replaced by backup router.
2627 Affected file silcd/packet_receive.c.
2629 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2631 * Fixed the backup resuming protocol to work in multiple
2632 router environment. Affected file silcd/server_backup.c.
2634 * Route packet only to one router in the function
2635 silc_server_packet_send_to_channel. Affected file is
2636 silcd/packet_send.c.
2638 * Fixed silc_server_send_notify_dest to set the broadcast
2639 flag. Fixed the silc_server_send_notify_topic to actually
2640 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2641 Affected file silcd/packet_send.c.
2643 * Changed the SFTP Filesystem interface. Changed the
2644 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2645 the filesystem operation function. The SilcSFTPFilesystem
2646 is now a context that is allocated by all filesystem allocation
2647 functions and it already includes the operations structure
2648 and filesystem specific context. It is given as argument
2649 now to the silc_sftp_server_start. This made the interface
2650 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2651 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2653 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2655 * Changed the backup router adding and getting interfaces
2656 in the server. The router that will be replaced by the
2657 specified backup router is now sent as argument. Affected
2658 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2661 * Added silc_net_addr2bin_ne to return the binary form of
2662 the IP address in network byte order. Affected files
2663 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2665 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2667 * Check for existing server ID in silc_server_new_server
2668 and in silc_server_connect_to_router_final and remove the
2669 old entry if it exists. Affected file silcd/packet_receive.c,
2672 * Send the channel message always to only one router, either
2673 in upstream or downstream. Affected file is
2674 silcd/packet_send.c.
2676 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2678 * Wrote the definition of the backup resuming protocol to the
2679 protocol specification.
2681 * Removed one redundant channel key generation from normal
2682 server during joining procedure. Removed one redundant
2683 channel key sending from server to router during joining
2684 procedure. Affected file silcd/command.c.
2686 * Made minor bugfixes to the backup router resuming protocol.
2687 Affected file silcd/server_backup.c, server.c.
2689 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * Added --disable-asm configuration option. Affected files
2692 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2695 * Implemented the backup resuming protocol that is used to
2696 resume the primary router position in the cell after the
2697 primary router comes back online. Affected files
2698 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2699 and silcd/server_util.[ch].
2701 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2703 * Sleep two (2) seconds after sending QUIT command to server.
2704 Affected file lib/silcclient/command.c.
2706 * Assure that if outgoing data buffer is pending do not force
2707 send any data. Affected file silcd/packet_send.c.
2709 * Assure that if outgoing data buffer is pending do not force
2710 send any data. Affected file lib/silcclient/client.c.
2712 * Implemented the backup router support when the primary router
2713 goes down. The servers and routers can now use the backup
2714 router as new primary router without loosing connectivity.
2716 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2718 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2719 in the server to indicate disabled entry. All data read
2720 from the connection will be ignored and no data is sent
2721 for entry that is disabled. Affected files are
2722 silcd/idlist.h, silcd/server.c.
2724 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2726 * Created SFTP client and server test programs in the
2727 lib/silcsftp/tests directory.
2729 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2731 * Implemented memory filesystem (virtual filesystem) for
2732 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2735 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2737 * Implemented the SFTP (SSH File Transfer Protocol) to the
2738 lib/silcsftp. It includes SFTP client and SFTP server
2741 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2743 * Moved lib/silccore/silcprotocol.[ch] to the
2744 lib/silcutil library.
2746 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2747 take variable argument list pointer as argument. Affected
2748 file lib/silcutil/silcbuffmt.[ch].
2750 * Added silc_buffer_set function that is used to set data
2751 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2752 Affected file lib/silcutil/silcbuffer.h.
2754 * Changed various routines in the core library to use the new
2755 silc_buffer_set instead of allocating new buffer only for
2758 * Added 64-bit value formatting and unformatting support to the
2759 silc_buffer_[un]format routines. Affected file is
2760 lib/silcutil/silcbuffmt.[ch].
2762 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2763 to includes/bitmove.h.
2765 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2767 * Fixed channel user mode saving in client library. Affected
2768 file lib/silcclient/command[_reply].c.
2770 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2772 * Defined the file transfer to the SILC Protocol. Added
2773 new packet type SILC_PACKET_FTP and defined File Transfer
2774 Payload. The mandatory file transfer protocol is SFTP
2775 (SSH File Transfer Protocol). Affected file in addition
2776 of the internet draft is lib/silccore/silcpacket.h.
2778 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2779 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2780 is used as part of backup router protocol when the primary
2781 router of the cell is back online and wishes to resume
2782 the position as primary router.
2784 * Redefined the MAC generation keys in the protocol. The
2785 same key is not used anymore in both direction. Both
2786 direction will now use different keys for sending and
2787 receiving. This fixes a potential security flaw. This
2788 change causes incompatibilities in the protocol.
2790 * Redefined also the MAC computation from the packet.
2791 An packet sequence number is now added to the MAC
2792 computation. This prevents possible replay attacks against
2793 the protocol. This change too causes incompatibilities
2796 Added `sequence' field to the SilcPacketContext to hold
2797 the current sequence number for the packet.
2799 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2801 * Added `created' field to the SilcIDListData in the file
2802 silcd/idlist.h to indicate the time when the entry was
2805 * Added `created' field to the SilcChannelEntry too. Affected
2806 file silcd/idlist.h.
2808 * Added `creation_time' aguments to all the announcement functions
2809 in the server. If it is provided then only the entries that
2810 was created after the provided time frame are actually
2811 announced. Affected file silcd/server.[ch].
2813 * The protocol says that the Channel ID's IP address must be
2814 based on the router's IP address. Added check for this in
2815 the silc_server_new_channel when processing incoming New Channel
2816 Payload. Affected file silcd/packet_receive.c.
2818 * Print out the correct version with --version in SILC client.
2819 Affected file irssi/src/silc/core/silc-core.c.
2821 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2823 * Fixed WHOWAS command to check for completnes of the client
2824 entry always, not just when the command is coming from client.
2825 Affected file silcd/command.c.
2827 * Added new function silc_server_packet_queue_purge to purge the
2828 outgoing data queue to the network. After the function returns
2829 it is guaranteed that the outgoing packet queue is empty.
2830 Affected file silcd/packet_send.[ch].
2832 * Purge the outgoing packet queue in the rekey protocol's final
2833 callback to assure that all rekey packets go to the network
2834 before quitting the protocol. Affected file silcd/server.c.
2836 * Added silc_client_packet_queue_parse as similar function as
2837 in server to the client library. The affected file is
2838 lib/silcclient/client.c.
2840 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2842 * Splitted silcd/server.c and created silcd/server_util.[ch]
2843 for utility functions.
2845 * Added new socket flag SILC_SF_DISABLED to indicate that the
2846 connection is open but nothing can be sent to or received from
2847 the connection. Affected file lib/silcutil/silsockconn.[ch].
2848 The checking for disabled socket is checked in the low level
2849 silc_socket_write and silc_socket_read functions.
2851 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2853 * Allow only nicknames and channel names that fits into the
2854 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2856 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2858 * When processing JOIN command reply in server check that if
2859 the channel exists in our global list we'll move it the local
2860 list. Affected file silcd/command_reply.c.
2862 * Fixed the check whether client is joined on the channel already
2863 in JOIN command. Affected file lib/silcclient/command.c.
2865 * Fixed the JOIN command reply to check whether the channel
2866 already exists. Affected file lib/silcclient/command_reply.c.
2868 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Added silc_ske_status_string to map the SKE error numbers
2871 to readable strings. The affected files are
2872 lib/silcske/silcske[_status].[ch].
2874 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2876 * Do not show the private channels on the WHOIS channel list
2877 as it is not allowed by the protocol. The affected file is
2880 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2882 * Assure that the packet length digged from the actual packet
2883 is something sensible in the silc_packet_decrypt_rest_special
2884 in lib/silccrypt/silcpacket.c.
2886 * Free and NULL the allocated pointer in silc_hmac_alloc if
2887 the HMAC allocation fails. The affected file is
2888 lib/silccrypt/silchmac.c.
2890 * Print the selected security properties to the log files in
2891 the server. Affected file silcd/protocol.c.
2893 * Add SKE's reference counter even if calling the completion
2894 callback manually. Otherwise it goes negative, although it
2895 does not cause any problems. The affected file is
2896 lib/silcske/silcske.c.
2898 * Remove the client entry with short timeout after giving the
2899 KILL command. Affected file lib/silcclient/command.c.
2901 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2902 case all found clients are already disconnected (WHOWAS would
2903 found them) in the server. Affected file silcd/command.c.
2905 * Update the last_receive (time of last data received) to be
2906 updated only when received private or channel message so that
2907 the idle time showed in WHOIS makes more sense.
2909 * Added boolean field `valid' in to the SilcClientEntry in the
2910 client library to indicate whether the entry is valid or not.
2911 This fixes the nickname change bug on channel when changing
2912 the nickname to be same than the old (like nick to Nick) the
2913 nickname formatter doesn't set the new nick anymore to Nick@host.
2914 Affected file lib/silcclient/idlist.[ch].
2916 * Now actually fixed the nickname changing on disconnection.
2917 Added new function silc_change_nick to the Irssi SILC Client.
2918 Affected file irssi/src/silc/core/client_ops.c,
2919 irssi/src/silc/core/silc-nicklist.[ch].
2921 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * Check that the public key exists in the GETKEY command before
2924 trying to encode it. Affected file silcd/command.c.
2926 * Print some notifications on received public keys with GETKEY
2927 command in the Irssi SILC Client. Affected files are
2928 irssi/src/fe-common/silc/module-formats.[ch],
2929 irssi/src/silc/core/client_ops.c.
2931 * Use IDENTIFY command to resolve the server information in the
2932 GETKEY command instead of INFO command. Affected file
2933 lib/silcclient/command.c.
2935 * All command reply functions in the client library now calls
2936 the pending command reply callbacks even if an error has
2937 occurred. The server has done this a long time and now it was
2938 time to move the client library to this as well. Now all
2939 errors can be delivered back to the pending command reply
2940 callbacks if necessary. Affected files are
2941 lib/silcclient/command[_reply].[ch].
2943 * Change the nickname on disconnection back to the username
2944 because in reconnect the server will enforce it to it anyway.
2945 Affected file irssi/src/silc/core/silc-servers.c.
2947 * Fixed a config file parsing bug in the Irssi SILC client.
2948 Affected file irssi/src/silc/core/clientconfig.c.
2950 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2952 * When printing the channel mode on JOIN, verify that the
2953 channel key and channel's HMAC are valid. Affected file
2954 irssi/src/silc/core/client_ops.c.
2956 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2958 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2959 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2960 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2962 * Removed channel key rekey task deleting from the function
2963 silc_server_save_channel_key. Affected file silcd/server.c.
2964 Added explicit timeout task context instead that is used to
2965 delete the task if we are registering a new task before the
2966 new task has elapsed.
2968 * When channel key rekey occurs the client library now saves
2969 the old channel key for a short period of time (10 seconds) and
2970 is able to use it in case some is still sending channel
2971 messages encrypted with the old key after the rekey. Affected
2972 file lib/silcclient/[idlist.h|client_channel.c].
2974 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2976 * Added check to the silc_server_new_id_real to not accept
2977 new ID if it is the sender's own ID. Affected file is
2978 silcd/packet_receive.c.
2980 * Assure that we do not announce ourself or the one we've
2981 sending our announcements when we're router and are announcing
2982 servers to our primary router. Affected file silcd/server.c.
2984 * Fixed silc_server_command_identify_check_client to assemble
2985 correct WHOIS packet. It send corrupted WHOIS packet and
2986 caused problem with router to router connections. Affected
2987 file silcd/command.c.
2989 Fixed also silc_server_command_whois_check the same way
2990 as for the IDENTIFY command.
2992 * Added new SilcIDListStatus to the server in the SilcIDListData
2993 structure. The status now includes the current status of
2994 the entry (like registered, resolved etc.). Affected file
2995 silcd/idlist.[ch]. Defined a bunch of different status types
2996 as well. This replaced the old boolean registered field as well.
2998 Added resolve_cmd_ident field to the SilcClientEntry structure
2999 too so that if the entry is for example being resolved so
3000 another command may attach to the same pending command reply
3001 without requiring to resolve the same entry again. This concept
3002 should optimize the WHOIS and the IDENTIFY resolving under
3003 heavy load by taking away unnecessary resolving for entries
3004 that are being resolved already.
3006 Added support for adding multiple pending commands for one
3007 command idenfier. Affected file silcd/command[_reply].[ch].
3009 * Fixed WHOIS and IDENTIFY save to remove the cache entry
3010 before deleting the data. Otherwise the hash table will have
3011 freed data in comparison functions. Affected file is
3012 silcd/command_reply.c.
3014 * Fixed silc_idlist_replace_client_id to add the new entry to
3015 the cache with NULL nickname. Otherwise there will be invalid
3016 memory as the nickname after the nickname is freed. Affected
3017 file silcd/packet_receive.c.
3019 * Fixed the silc_idlist_get_clients_by_hash. The entries was
3020 saved into wrong slots because the previous number of entries
3021 was not taken into account. Affected file silcd/idlist.c.
3022 Fixed same thing in silc_idlist_get_clients_by_nickname too.
3024 * If we are router and we receive JOIN notify to a channel that
3025 does not have any users then notified client is marked as the
3026 channel founder, as it is it. The affected file is
3027 silcd/packet_receive.c
3029 * Added to the extended hash table API's table_del_*ext functions
3030 the destructor as argument too, so that the caller can decide
3031 which destructor to use or whether to use destructor at all.
3032 Affected file lib/silcutil/silchashtable.[ch].
3034 * Fixed ID Cache purging. It actually deleted the entries from
3035 the hash table after the data was freed. The hash table ended
3036 up comparing freed memory. The affected file is
3037 lib/silccore/silcidcache.c.
3039 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3041 * Fixed Irssi SILC client's KILL command's HELP syntax.
3043 * The USERS command now resolves the detailed user information
3044 if the userinfo field is missing. Affected file is
3045 lib/silcclient/command_reply.c.
3047 * Do not print error in silc_file_read if the read file does
3048 not exist. Just silently return NULL. Affected file is
3049 lib/silcutil/silcutil.c.
3051 * Fixed the silc_log_output to not wine about NULL filename
3052 and to not create some bogus " " filename. Affected file is
3053 lib/silcutil/silclog.c.
3055 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3057 * Fixed various printing bugs on the user interface in the
3058 Irssi SILC Client. Minor changes that were forgotten from
3061 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3063 * Fixed the configure.in.pre and the compilation and distribution
3064 environment to support the new autoconf 2.52. That version is
3065 now required to compile the CVS trunk.
3067 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3069 * Renamed function silc_parse_nickname to silc_parse_userfqdn
3070 to generally parse user@fqdn format strings. Affected file
3071 lib/silcutil/silcutil.c.
3073 * Added nickname_format and nickname_force_format fields to the
3074 SilcClientParams structure. The first one defines the format
3075 for the nicknames that the library will enforce if the receives
3076 multiple same nicknames. The second one is boolean value and
3077 can be used to force the library to always enforce the format
3078 to the nicknames regardles whether there are multiple nicknames
3079 or not. This configurable formatting was employed to flexibly
3080 support accessing multiple nicknames from the user interface.
3081 The userinterface can now set the nicknames to what ever format
3082 they prefer. Affected file lib/silcclient/silcapi.h.
3084 Added function silc_client_nickname_format to the file
3085 lib/silcclient/idlist.c. It performs the nickname formatting.
3087 Added new field `hostname´ to the SilcClientEntry context.
3088 It holds the hostname of the client. Affected file is
3089 lib/silcclient/idlist.h.
3091 * Irssi SILC Client sets the nicknames in nick@hostn format.
3092 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
3093 irssi/src/silc/core/silc-core.c.
3095 The WHOIS printing now also shows both the real nickname and
3096 the formatted nickname so that user knows how to access the
3097 user if there are multiple same nicknames cached. Affected
3098 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
3099 printing formatting too to take the hostname now as a separate
3100 argument. The Affected file is
3101 irssi/src/fe-common/silc/modules-formats.[ch].
3103 * Changed the silc_client_get_clients_local to accept the formatted
3104 nickname as argument. It accepts the real nickname too but the
3105 formatted nickname can be used to find the true entry from
3106 multiple entries. Affected file lib/silcclient/silcapi.h and
3107 lib/silcclient/idlist.c.
3109 * Added nickname_format_parse field to the SilcClientParams.
3110 It is a callback function provided by the application to parse
3111 the nickname out of the formatted nickname string. The library
3112 calls it to get the nickname from the formatted string. Since
3113 the application generally knows better the format of the nickname
3114 string it parses it instead of the library, even though library
3115 encodes the formatted string. If the callback function is not
3116 provided then the library will use the string as is. The
3117 affected file is lib/silcclient/silcapi.h.
3119 * All the nickname strings passed to the client library in
3120 commands are now expected to be formatted nickname strings.
3121 If the command does not support the formatted nickname string
3122 it will assume that the sent string is the actual nickname.
3123 Affected file lib/silcclient/command.c.
3125 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3127 * Added public key authentication support to OPER and SILCOPER
3128 commands in the client library. Affected file is
3129 lib/silcclient/command.c.
3131 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3133 * Changed the get_auth_methdod client operation to be asynchronous.
3134 It can be async if the application resolves the authentication
3135 method from the server during the negotiation. Added new
3136 SilcGetAuthMeth completion callback that the application will
3137 call after resolving the authentication method.
3139 Added function silc_client_request_authentication_method that
3140 the application can use to resolve the authentication method
3141 from the server. Added also SilcConnectionAuthRequest callback
3142 that the library will call after the server has replied. The
3143 application can call this function if it does not know the
3144 current authentication method.
3146 Affected files are lib/silcclient/client.c and
3147 lib/silcclient/silcapi.h.
3149 * The Irssi SILC client now automatically resolves the authentication
3150 method incase any configuration information is not present (and
3151 currently there never is). The affected file is
3152 irssi/src/silc/core/client_ops.c.
3154 * Fixed public key authentication from the client library.
3155 Affected file lib/silcclient/protocol.c. Changed also the
3156 protocol specification about the public key authentication in
3157 the connection authentication protocol. The actual data to be
3158 signed is now computed with a hash function before signing.
3160 * Fixed the public key authentication from the server as well.
3161 Affected file silcd/protocol.c.
3163 * Removed the mlock()'s from the memory allocation routines.
3164 Affected file lib/silcutil/silcmemory.c. The ./configure does
3165 not check anymore for the mlock(). Affected file is
3168 * Fixed USERS command in server to allow the execution of the
3169 command for private and secret channels if the client sending
3170 the command is on the channel. Affected file silcd/command.c.
3172 * Fixed silc_client_get_clients_local to return the clients
3173 count correctly. It could return wrong value. Affected file
3174 lib/silcclient/idlist.c.
3176 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3178 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
3179 types. The assembler optimizations seemed not to like 64-bit
3180 data types. The assmebler optimizations thus are now enabled
3181 also for BSD systems as opposed to only enable them for Linux.
3183 * Do not check for threads at all on BSD systems. Affected
3184 file configure.in.pre.
3186 * Removed -n and -h options from the Irssi SILC Client since
3187 they are not used in silc.
3189 * Fixed the prime generation to assure that the first digit
3190 of the generated random number is not zero since our conversion
3191 routines does not like number strings that starts with zero
3192 digit. If zero digit is seen the random number is regenerated.
3193 This caused some corrupted RSA keys when the zero first digit
3194 was met. Affected file lib/silcmath/silcprimegen.c.
3196 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3198 * Fixed WIN32 configuration in the ./configure script.
3199 Fixed to include xti.h on environments that has it.
3200 Patches by Carsten Ilchmann and andrew.
3202 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3204 * Changed the silc_id_create_client_id to be collision
3205 resistant. It is now assured that there cannot be created
3206 two same client ID's. I suspect that some weird bugs in
3207 the server were actually caused by duplicate Client IDs.
3208 Affected file silcd/serverid.[ch]. A router receiving
3209 new ID now also assures and informs the sending server
3210 if the ID caused collision.
3212 * Changed the silc_id_create_channel_id to also assure that
3213 there are no collisions.
3215 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3217 * Statement about ignoring the Mutual Authentication flag when
3218 performing rekey with PFS was a bit misleading. It is ignored
3219 if it was set in the initial negotiation, it cannot be even
3220 set in the rekey. Fixed in the ke-auth draft. Started the
3221 new versions of the protocol drafts in the doc/.
3223 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3225 * Fixed a bug in silc_client_command_identify_save when saving
3226 new channel information. The channel name was no duplicated
3227 and caused crash on exit. Affected file is
3228 lib/silcclient/command_reply.c.
3230 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3232 * Fixed the getkey command handling in the server. Send just
3233 empty OK reply to the sender if the key could not be fetched
3234 (but everything else was ok, like the key just was not available).
3235 Changed the public key parameter to optional in the protocol
3236 specs so that empty OK reply can be sent. Affected file
3239 Added a message to Irssi SILC client to tell to user if the
3240 server did not return a public key.
3242 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
3244 * Fixed a channel key regeneration bug. It registered new
3245 timeout tasks exponentially until all system resources were
3246 used. Affected file silcd/server.c.
3248 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3250 * Added the SILC Document generator to the scripts/silcdoc.
3251 It can be used to generate the Toolkit Reference Manual out
3252 of the source tree. Internally it will also use the RoboDoc
3253 generator now imported in util/robodoc.
3255 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3257 * Added couple of return's in rekey protocol if error orccurred
3258 during the protocol. The execution must be terminated.
3259 Affected file silcd/protocol.c. Also, terminate the protocol
3260 always with timeout.
3262 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3264 * The client's Client ID was created initally from the wrong
3265 nickname (it could have been in format nick@host) in the
3266 silc_server_new_client. Affected file silcd/packet_receive.c
3268 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3270 * Added some SILC_LOG_ERROR's to various error conditions
3271 if client could not be added to ID cache. Affected files
3272 silcd/packet_receive.c and silcd/server.c.
3274 * When client's sock->user_data is freed, NULL also the
3275 client->router and client->connection pointers. Added check
3276 for these pointers being NULL to various places around the
3277 code. Affected file silcd/server.c.
3279 * Added client->data.registered == TRUE checks to various
3280 places around the code to assure that unregistered client's
3281 are not handled when it is not allowed. Affected file
3284 * Added `bool registered' fields to all
3285 silc_idlist_[server|client]_get_* routines to indicate whether
3286 the fetched client needs to be registered or not. Affected
3287 file silcd/idlist.[ch].
3289 * Add your own entry as registered to the ID cache in the
3290 server. Affected file server.c.
3292 * Fixed a bug in silc_server_new_server. The SilcServer was
3293 set as the new server's context instead of SilcServerEntry.
3294 This naturally caused some weird bugs.
3296 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3298 * Do not delete the channel rekey task when adding it
3299 for in silc_server_create_channel_key.
3301 * Changed the silc_server_create_channel_key to return
3302 TRUE or FALSE to indicate the success of the channel key
3305 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3307 * Fixed MSVC++ project files and added missing files to
3308 Makefiles under win32/.
3310 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3312 * Do not add TCP_NODELAY flag if the operating system
3313 does not have it defined. Affected files are
3314 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
3316 * Fixed buffer overflow from Irssi SILC Client. Affected
3317 file irssi/src/fe-common/core/themes.c.
3319 * Fixed double free in client library in the file
3320 lib/silcclient/client.c when disconnecting from server.
3322 * Applied double free patch from cras to Irssi SILC client.
3323 Affected files irssi/src/core/[modules/expandos].c
3325 * Fixed the disconnection handling to Irssi SILC Client.
3326 The application must call silc_client_close_connection
3327 in ops->connect client operation in case of failure of
3328 the connection. Affected file is
3329 irssi/src/silc/core/client_ops.c.
3331 * Do not set sock->protocol to NULL in the function
3332 silc_client_close_connection after executing the protocol's
3333 final callback since the sock might not be valid anymore.
3334 Affected file lib/silcclient/client.c.
3336 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3338 * Do not enable SILC_THREADS if the linking with libpthread
3339 did not happen. Affected file configure.in.pre.
3341 * Added notion to protocol specification that server must
3342 verify the sent authentication payload with CMODE when
3343 setting the channel founder key. Implemented it to the
3344 server. Affected file silcd/command.c.
3346 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3348 * Added _EXTRA_DIST SILC distribution variable to the
3349 distributions file. It is used to conditionally add extra
3350 files or directories to the specific distribution. Affected
3351 files ./prepare, Makefile.am.pre and distributions.
3353 Removed the `_' from the start of the distribution names.
3356 * Added README.WIN32 for instructions to compile the Toolkit
3359 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3361 * Fixed a double free in disconnection in the server. Affected
3362 file is silcd/server.c.
3364 * Fixed the lib/silcske/groups.c to work now also with GMP
3365 MP library. The string conversion did not work when using
3366 specific base and the base is indicated in the string as well.
3368 * Created win32/ directory which now includes MSVC++ specific
3369 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3370 It will appear only in the toolkit distribution
3372 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3374 * Changed the key material distribution function in case when
3375 the hash output is too short. The data is now concatenated
3376 a bit differently than it used to. Made the change to the
3377 SKE protocol specification.
3379 * Added better GMP detection to configure.in.pre. A patch
3382 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3384 * Fixed a minor bug in SKE that might cause some problem on
3385 some platforms. Affected file lib/silcske/silcske.c.
3387 * Added the cookie checking for initiator in the SKE. It checks
3388 that the responder returns the sent cookie unmodified. The
3389 affected file is lib/silcske/silcske.c. Added new SKE
3390 error type INVALID_COOKIE that can be sent during the
3391 negotiation. Fixed some memory leaks as well.
3393 * Added the "invalid cookie" error message to Irssi SILC client's
3396 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3398 * Added `task_max' field to the SilcClientParams to indicate
3399 the maximum tasks the scheduler can handle. If set to zero,
3400 default values are used. Affected file lib/silcclient/silcapi.h.
3402 * Fixed memory leaks in silc_client_close_connection. Affected
3403 file lib/silcclient/client.c.
3405 * Added silc_client_del_client_entry to client library to free
3406 all memory of given client entry. Affected file is
3407 lib/silcclient/idlist.[ch].
3409 * Added new functions silc_client_del_channel and
3410 silc_client_del_server to delete channel and server entries.
3411 Affected file lib/silcclient/[silcapi.h/idlist.c].
3413 * Removed silc_client_del_client_by_id from silcapi.h.
3415 * Fixed the INFO command to return the server's own info
3416 correctly when querying by Server ID. Affected file is
3419 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3421 * Removed the non-blocking settings in WIN32 code in the
3422 silc_sock_[read/write] and added SleepEx instead. Affected
3423 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3424 of input data is now checked with FIONREAD and ioctlsocket.
3426 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3428 * Call silc_schedule_task_del_by_context in the
3429 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3430 Affected file lib/silccore/silcprotocol.c.
3432 * Call silc_protocol_cancel for active protocols in the
3433 silc_server_close_connection if the funtion
3434 silc_server_free_sock_user_data has not been called.
3435 Affected file silcd/server.c.
3437 * Generic tasks cannot be deleted using the del_by_fd
3438 task deleting function since generic tasks does not match
3439 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3441 * Added a notion to SILCOPER help file that the SILCOPER works
3442 only on router server, not on normal server.
3444 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3446 * Added for WIN32 support for the new scheduler as well.
3447 Affected file lib/silcutil/win32/silcwin32schedule.c.
3449 * Fixed the SHA1 implementation to work on various platforms.
3451 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3453 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3454 API. It is part of the scheduler now. Everything else is
3455 as previously but some functions has changed their names.
3456 Checkout the lib/silcutil/silcschedule.h for the interface.
3457 Updated all applications to use the new interface. Affected
3458 files are lib/silcutil/silcschedule.[ch].
3460 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3462 * Found a bug in the SKE implementation. The HASH value,
3463 specified by the protocol, was not computed correctly. The
3464 public key of the responder was not added to the computation
3465 even though it is mandatory. Affected file lib/silcske/silcske.c.
3466 This unfortunately causes incompatibilities with older
3467 clients and servers.
3469 * Added WIN32 specific network init and uninit functions:
3470 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3471 the Winsock2. Affected file lib/silcutil/silcnet.h and
3472 lib/silcutil/win32/silcwin32net.c.
3474 * Set the socket always to nonblocking mode on WIN32 after
3475 reading data or writing data. Affected file is
3476 lib/silcutil/win32/silcwin32sockconn.c.
3478 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3480 * Fixed various compilation problems under WIN32. Affected
3481 files lib/silcutil/win32/silcwin32thread.c and
3482 lib/silcutil/win32/silcwin32schedule.c.
3484 * Removed all _internal.h #includes from public header
3485 files. Internal headers must never be included from
3488 Removed also the lib/silcske/payload_internal.h file.
3490 * All include files that may be needed (public and some others
3491 included by the public headers) by application developers are
3492 now copied to the ./includes directory. It does not copy any
3493 internal headers. Affected file Makefile.defines.pre and all
3494 Makefile.am's under lib/ and subdirs.
3496 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3498 * Do not change the ~/.silc directory's permissions automatically.
3499 Affected file irssi/src/silc/core/clientutil.c.
3501 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3503 * Do not cancel the protocol in silc_server_close_connection
3504 it might cause recursion. Now cancelled in the function
3505 silc_server_free_sock_user_data. Affected file silcd/server.c.
3507 * Fixed the silc_server_remove_clients_by_server to regenerate
3508 the channel keys correctly finally. Added also new function
3509 silc_server_remove_clients_channels to actually do it.
3510 Affected file silcd/server.c.
3512 * Fixed the silc_server_new_channel to not crash by giving
3513 wrong router to the new channel. Affected file is
3514 silcd/packet_receive.c.
3516 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3518 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3519 which is given as argument to the silc_client_alloc now.
3520 It can be used to configure the client and set various parameters
3521 that affect the function of the client.
3523 * The USERS command in server did not check whether the channel
3524 is private or secret. Affected file silcd/command.c.
3526 * Added new argument to the USERS command in protocol specification.
3527 The USERS command now can take the channel name as argument
3528 as well. Added support for this in client and server and
3529 updated the protocol specs.
3531 * Completed the GETKEY command in client. It can be now used
3532 to fetch also servers public key not only some clients.
3533 Affected files lib/silcclient/command[_reply].c.
3535 * Added silc_client_get_server to return server entry by the
3536 server name. Affected files lib/silcclient/silcapi.h and
3539 * Redefined the IDENTIFY command in protocol specification to be
3540 more generic. It now can be used to query information about
3541 any entity in the SILC Network, including clients, servers and
3542 channels. The query may be based either the entity's name
3543 or the ID. Added support for this in both client and server.
3545 Affected files silcd/command.c and lib/silcclient/command.c
3546 and command_reply.c.
3548 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3549 the _from_client and _from_server functions. Affected file
3552 * Added silc_client_get_channel_by_id_resolve to the file
3553 lib/silcclient/silcapi.h to resolve channel information by
3554 its ID. Added also silc_client_get_channel_by_id that
3555 does not resolve it from the server.
3557 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3559 * Added SilcServerEntry context into the client library
3560 to represent one server. The INFO command now allocates
3561 these to save the resolved server info. For now on the
3562 client library will also keep information about servers,
3563 connected and resolved with INFO.
3565 The INFO command now allocates the SilcServerEntry context
3566 and saves the server info there. The COMMAND_REPLY in
3567 the INFO now returns the parameters to application in
3568 same order as defined in the protocol specification.
3570 The entries are cached in the client->server_cache.
3572 * The INFO command is now issued after received the Client ID
3573 from the server. Affected file lib/silcclient/client.c.
3575 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3576 to the application as the mode changer might be server.
3577 It is guaranteed that NULL is not returned anymore to the
3578 application. Affected file lib/silcclient/client_notify.c.
3580 The ID Type is now also passed to the application so that
3581 it can check whether the returned entry is SilcClientEntry
3584 Added new function silc_client_get_server_by_id to return
3585 the server entry by ID. Affected files are the
3586 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3588 * Do not create the channel in the Irssi SILC Client when issuing
3589 the JOIN command but when received the sucessful JOIN command
3590 reply. Otherwise the channel might get created even though we
3591 could not join it. The Affected file is
3592 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3594 * Fixed a channel joining bug in router. The router must also
3595 check the channel modes, invite and ban lists etc. when serving
3596 the JOIN command sent by normal server. Affected file is
3597 silcd/command.c. The router now resolves the client's
3598 information from the server who sent the JOIN command if it
3599 does not know it, and processes the JOIN command only after
3602 * Changed the SilcCommandCb to take new argument; void *context2.
3603 Affected file lib/silccore/silccommand.h
3605 The second argument in the command callbacks in the server now
3606 includes the SilcServerCommandReplyContext if the command was
3607 called as pending command callback from the command reply.
3608 Otherwise it is NULL. When called as pending the status of the
3609 command reply will be checked and if it was erronous the
3610 error will be sent to the original sender of the command.
3611 This way the client always receives the error messages even
3612 though the server was actually the one who received the error
3613 when it resent the command to router, for example. Affected
3614 files silcd/command[_reply].[ch].
3616 * Fixed sending WHOWAS command's error message to client if
3617 the requested client could not be found. It was missing.
3620 * Changed the CMODE and CUMODE commands reply arguments in the
3621 protocol specification. The Channel ID is now sent in both
3622 of the commands to identify the channel. Implemented this
3623 new feature to the client and server. Affected files
3624 lib/silcclient/command_reply.c and silcd/command.c.
3626 * Made better checks for invite and ban lists in the JOIN
3627 command in server. Affected file silcd/command.c.
3629 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3631 * The server now performs the incoming host IP/DNS lookup
3632 using the silc_socket_host_lookup and thus does not block
3633 the server anymore. Affected file silcd/server.c.
3635 * Completed the multi-thread support for SILC Scheduler in
3636 the lib/silcutil/silcschedule.c.
3638 * Fixed the configure.in.pre to detect the pthread correctly
3641 * Fixed a deadlock in silc_task_queue_wakeup in the file
3642 lib/silcutil/silctask.c.
3644 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3646 * Added new function silc_schedule_wakeup that is used in
3647 multi-threaded environment to wakeup the main thread's
3648 schduler. It needs to be used when a thread adds a new task
3649 or removes a task from task queues. After waking up, the
3650 scheduler will detect the task queue changes. If threads
3651 support is not compiled in this function has no effect.
3652 Implemented the wakeup mechanism to both Unix and WIN32
3653 systems. Affected files are lib/silcutil/silcschedule.[ch],
3654 lib/silcutil/unix/silcunixschedule.c and the
3655 lib/silcutil/win32/silcwin32schedule.c.
3657 * Added new function silc_task_queue_wakeup to wakeup the
3658 scheduler by the specified task queue. Affected file
3659 lib/silcutil/silctask.[ch].
3661 * The silc_socket_host_lookup_start now wakes up the scheduler
3662 after adding the timeout task. Affected file is
3663 lib/silcutil/silcsockconn.c.
3665 * The silc_socket_host_lookup is synchronous now if the threads
3666 support is not compiled in. However, the callback is still
3667 called asyncronously through the scheduler, anyway. Affected
3668 file lib/silcutil/silcsockconn.c.
3670 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3672 * Added new function silc_socket_host_lookup to perform
3673 asynchronous IP and FQDN lookups for the socket connection.
3674 Affected files lib/silcutil/silcsockconn.[ch].
3676 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3678 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3679 that may or may not compile the mutex support in.
3681 Changed the silc_mutex_alloc interface. It allocates the
3682 mutex now to the sent pointer and returns TRUE or FALSE.
3684 Affected file lib/silcutil/silcmutex.h.
3686 * Wrote the SILC Task Queue interface to support multi-threads.
3687 Affected file lib/silcutil/silctask.[ch].
3689 * Wrote the SILC Scheduler to support multi-threads. Affected
3690 file lib/silcutil/silcschedule.c.
3692 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3694 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3695 in lib/silcutil/win32/.
3697 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3699 * Defined SILC Mutex API and SILC Thread API and implemented
3700 them for Unix. Affected files are
3701 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3702 lib/silcutil/unix/silcunixmutex.c and
3703 lib/silcutil/unix/silcunixthread.c.
3705 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3707 * Fixed the silc_server_remove_clients_by_server's channel
3708 key re-generation. The hash table handling was incorrect
3709 and would not work with many channels. Affected file is
3712 * Fixed some memory leaks around the server code.
3714 * Rewrote the silc_server_get_users_on_channel to support IPv6
3715 based Client ID's. Affected file silcd/server.c.
3717 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3718 specification. However, a separate document must be written
3719 to define the detailed signing procedure and the payload
3720 associated with the flag. Defined the flag to the
3721 lib/silccore/silcchannel.h as well.
3723 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3725 * Changed the dynamic tables to static size tables in the
3726 lib/silccrypt/silchmac.c.
3728 * Removed GCC dependencies from the code. A patch by cras.
3730 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3732 * Do not show the error "Error receiving packet bla bla"
3733 in server if it really was not an error (-2 means that reading
3734 is pending). Affected file silcd/server.c.
3736 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3738 * Fixed a possible crash in silc_server_remove_clients_by_server
3739 in silcd/server.c. Fixed there also some memory leaks.
3741 * Fixed the silc_idlist_replace_client_id. It could replace
3742 wrong key in the hash table. Affected file silcd/idlist.c.
3744 * Do not check whether there are global users on the channel
3745 if the channel->global_users is FALSE. Affected functions
3746 silc_server_remove_from_one_channel and
3747 silc_server_remove_from_channels in silcd/server.c. Also,
3748 do not check if the removed client is local as we can be
3749 sure that global client was not removed from the channel
3750 and checking for global users is not needed.
3752 * The silc_server_remove_clients_by_server now re-generates
3753 the channel keys correctly for those channels that had
3754 clients removed from them. Affected file silcd/server.c.
3756 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3758 * Found the reason of random crashes in the server. We weren't
3759 ignoring the SIGPIPE signal (which can be sent in write())
3760 and it crashed the server. Affected file silcd/silcd.c.
3762 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3764 * Assure that sock->user_data is not NULL in the function
3765 silc_server_packet_send in silcd/packet_send.c.
3767 * Disconnect the remote connection if it could not be added
3768 to any ID lists in the server. The affected file is
3771 * Check in silc_server_packet_send[_real/dest] that the
3772 socket is not disconnecting and ignore the data if it is.
3773 Affected file silcd/packet_send.c.
3775 * Define inline to __inline on native WIN32 compilation.
3776 Affected file includes/silcwin32.h.
3778 * Added some explicit type casts for inline code since MSVC
3779 require them. Affected files lib/silcutil/silcbuffer.h,
3780 lib/trq/silcdlist.h and lib/trq/silclist.h.
3782 * Print warning in log files from now on if the packet
3783 decryption fails. Affected file silcd/server.c.
3785 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3787 * Changed the `say' client operation's interface to accept
3788 new `type' argument to indicate the type of the message sent
3789 by the library. The application may filter the library's
3790 messages according the type. The affected file is the
3791 lib/silcclient/silcapi.h.
3793 * Added two new functions to lib/silcclient/silcapi.h:
3794 silc_client_del_client and silc_client_del_client_by_id.
3795 Affected file lib/silcclient/idlist.c.
3797 * Moved the clientincludes.h from includes/ to silc/ and
3798 serverincludes.h from includes/ to silcd/.
3800 * The modes for the CMODE and CUMODE are now passed as
3801 uint32 for application with COMMAND_REPLY. The affected
3802 file is lib/silcclient/command_reply.c.
3804 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3806 * /WHOIS without arguments shows client's own information.
3807 Affected file lib/silcclient/command.c.
3809 * Changed PING to not accept any arguments. The specs
3810 says that client can ping only the connected server so
3811 requiring an argument is not needed. Affected file is
3812 lib/silcclient/command.c.
3814 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3816 * Fixed a fatal bug in private message sending and reception
3817 encryption and decryption when using private message keys.
3818 The implementation was incorrect and did not follow the
3819 specification. It causd that some of the message were
3820 lost since it did not use the sending and receiving keys
3821 as the protocol suggests. This has been fixed and will cause
3822 incompatibilities with older clients when sending private
3823 message encrypted with private message keys. Affected files
3824 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3825 and various other in Irssi SILC Client.
3827 Added `responder' boolean argument to the functions
3828 silc_client_add_private_message_key[_ske] to indicate when
3829 the key is added as responder or initiator of the key
3832 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3834 * Removed the silc_ske_check_version function and created
3835 a SilcSKECheckVersion callback. Added also a function
3836 silc_ske_set_callbacks that is now used to set all SKE
3837 callbacks. The callback functions are not given to
3838 the SKE functions anymore, but this function is used to
3841 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3843 * Added `silc_version' argument to the silc_client_alloc
3844 to define the version of the application for the library.
3845 The library will use the version string to compare it
3846 against the remote host's (usually a server) version
3847 string. Affected file lib/silcclient/silcapi.h
3849 * Added the KE protocol context to Key Agreement context
3850 in client library so that we can abort the SKE if it
3851 is in process when we get timeout. Affected file is
3852 lib/silcclient/client_keyagr.c.
3854 * Do not resolve the client ID forever if it returns in the
3855 first time that such client does not exist. This was done
3856 for example with private message. Affected file is
3857 lib/silcclient/client_prvmsg.c.
3859 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3861 * Do not add regex.h for WIN32. The affected file
3862 includes/silcincludes.h.
3864 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3865 not work yet 100%. It generates the DLL's automatically
3866 when compiling with --with-win32 under cygwin.
3868 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3870 * lib/contrib/regex.c is not compiled on WIN32.
3872 * Added silc_net_get_socket_opt function to the
3873 lib/silcutil/silcnet.h.
3875 * Added includes/silcwin32.h for WIN32 specific includes
3878 * Do not use ptime structure or any of the posix process
3879 functions on WIN32 in lib/silccrypt/silrng.c.
3881 * Added silc_gettimeofday to provide generic function
3882 for struct timeval on all platforms. Added the function
3883 to lib/silcutil/silcutil.h.
3885 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3887 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3888 library as they clearly belong there. As a plus side we
3889 can make the actual socket connection routines platform
3892 Added also new generic function silc_socket_read and
3893 silc_socket_write (that used to be silc_packet_[read/write].
3894 The implementation of these are platform specific.
3896 * Added WIN32 specific routines of silc_socket_[read/write]
3897 to lib/silcutil/win32/silcwin32sockconn.c.
3899 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3901 * Added preliminary support for native WIN32 compilation under
3902 cygwin (using the -mno-cygwin option for GCC) to the
3903 ./configure.in.pre. The --with-win32 now prepares the
3904 compilation for native WIN32.
3906 * Rewrote the SILC Scheduler interface in the file
3907 lib/silcutil/silcschedule.h. The scheduler is now context
3908 based and does not have anymore any global static scheduler.
3909 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3910 and created lib/silcutil/win32 directory for WIN32 based
3913 * Added Unix specific network routines to the
3914 lib/silcutil/unix/silcunixnet.c and the old
3915 lib/silcutil/silcnet.c includes now only generic routines.
3917 Added WIN32 specific network routines to the
3918 lib/silcutil/win32/silcwin32net.c.
3920 * Added Unix specific utility functions from the
3921 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3923 * Added WIN32 SILC Scheduler to the file
3924 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3927 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3929 * Do not handle JOIN notify in the server if the target client
3930 is not registered (idata->registered == FALSE). The affected
3931 file is silcd/packet_receive.c.
3933 * Update the nickrec->founder in event_cumode in the Irssi SILC
3934 client. Affected file irssi/src/silc/core/silc-channels.c.
3936 * Fixed the CUMODE_CHANGE notify handling in the server when
3937 server and router are announcing their clients on channels.
3938 Now the mode changes are saved and notified correctly. The
3939 affected file is /silcd/packet_receive.c.
3941 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3942 They really did not replace the cache entry in the ID Cache.
3943 Now they do that. Affected file silcd/idlist.c.
3945 * Fixed the KICK notify handling in the Irssi SILC client to
3946 update the channel records so that the kicked client does not
3947 appear to be on the channel. The affected file is
3948 irssi/src/silc/core/silc-channels.c.
3950 * Always update the conn->current_channel when executing command
3951 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3953 * Fixed the KILL notify handling in Irssi SILC client to remove
3954 the killed client on all channels.
3956 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3958 * Fixed the silc_parse_command_line to remove extra spaces
3959 from the start and end of the arguments. Affected file is
3960 lib/silcutil/silcutil.c.
3962 * Cancel and free any active protocol in the function
3963 silc_server_close_connection. Affected file silcd/server.c.
3965 * Cancel and free any active protocol in the function
3966 silc_client_close_connction. Affected file is
3967 lib/silcclient/client.c.
3969 * Do not execute the KILL command for clients that are in
3970 history (ie. they are not in the network). Affected file is
3973 * Fixed KILL notify handling, client does not crash anymore.
3974 Affected file irssi/src/silc/core/silc-channels.c.
3976 * Reduced the default packet buffer size from 2048 to 1024 in
3977 lib/silccore/silcpacket.c.
3979 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3980 counter to the SKE context that is incresed when the SKE library
3981 performs async operation outside the library. If the outside
3982 process frees the SKE context and FREED status will be set
3983 and the library will detect after the sync operation that the
3984 libary is freed. The affected files are
3985 lib/silcske/silcske[_status].[ch].
3987 * Resolve the client entry information in the function
3988 silc_client_channel_message to assure that NULL pointer is not
3989 passed as client entry to the application. */
3991 * Fixed the task timeout calculation to assure that there is
3992 never negative timeouts. The affected file is
3993 lib/silcutil/silcschedule.c.
3995 * Fixed the channel user mode notification sending in server.
3996 It was sent point-to-point to the router (or to server by router)
3997 but it needs to be destined to a channel. The routines now
3998 supports sending the channel user mode notifys to the channels
3999 when announcing clients and channels. Affected files are
4000 silcd/server.c and silcd/packet_receive.c.
4002 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
4003 It did not actually replace the old channel entry in the cache.
4004 Affected file lib/silcclient/client_notify.c.
4006 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Fixed a possible crash in silc_packet_send_prepare. It now
4009 assures always that there is enough space in the buffer and
4010 at the tail area of the buffer (for MAC).
4012 Fixed the inbound buffer reallocation in silc_packet_read.
4013 It was old code and did not handle the reallocation correctly.
4016 The affected file is lib/silccore/silcpacket.c.
4018 * Fixed buffer overflow in silc_parse_nickname in the file
4019 lib/silcutil/silcutil.c.
4021 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4023 * make install generates new server keys only if there is not
4026 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4028 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
4029 Added check that if the NOREPLY is set then we will not send
4030 the away message. This avoids infinite loop of away messages
4031 if both clients are away. The affected file is
4032 lib/silcclient/client_prvmsg.c.
4034 * Fixed client crash if /NICK was given without arguments.
4035 Affected file lib/silcclient/command.c.
4037 * Server does not send the invite list in INVITE command back
4038 to the client if the list was not altered. Added this notion
4039 to the protocol spec as well. Affected file silcd/command.c.
4041 Fixed possible crash in INVITE command by checking the
4042 value of silc_server_get_client_route command.
4044 * Fixed the INVITE notify type handling. The arguments are now
4045 taken in correct order and client does not crash. The affected
4046 file is irssi/src/silc/core/silc-channels.c.
4048 Removed the "Inviting xxx to channel" message from the
4049 client library away and let the application handle it.
4050 Affected file lib/silcclient/command.c. Added that message
4051 to Irssi SILC client's message formats.
4053 * Fixed CMODE command crash in client. It now checks the
4054 amount of arguments correctly and does not crash. The affected
4055 file is lib/silcclient/command.c.
4057 * Do not create new channel automatically in silc_channels_join
4058 but check whether the channel by that name already exists.
4059 Affected file irssi/silc/core/silc-channels.c.
4061 * Do not send the SERVER_SIGNOFF to router if the disconnected
4062 entity was the router. Affected file silcd/server.c.
4064 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
4065 SILC client as it was missing from there.
4067 Added the handling of the KICK notify to the Irssi SILC client
4068 as it was missing. Added "you have been kicked" message to
4069 Irssi SILC client's message modules formats.
4071 Added the handing of the KILL notify to the Irssi SILC client
4072 as it was missing. Added the kill message module formats
4075 The affected file is irssi/src/silc/core/silc-channels.c.
4077 * The router did not save the channel mode the server announced.
4078 Affected file silcd/packet_receive.c.
4080 * Fixed a possible crash in INFO command in server. If the
4081 server did not provide the server info it crashed. Affected
4082 file silcd/command.c.
4084 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4086 * Fixed the GETKEY command in the server to check also the
4087 global list. Otherwise the GETKEY would not work correctly
4088 in normal SILC server. Affected file silcd/command.c.
4090 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4092 * Fixed GETKEY crash, it crashed if the command did not succseed.
4094 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4096 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
4097 is now real and not just an macro interface to GMP.
4099 Removed the entire GMP from the source tree and imported new
4100 NSS MPI library instead. Reason for removing GMP is that it is
4101 extremely large and compiles extremely slow. The NSS MPI
4102 is only a few files and compiles in less than 10 seconds.
4103 The speed is also about the same as GMP. The MPI is imported
4104 to lib/silcmath/mpi.
4106 If the system has GMP installed we will still use the GMP.
4107 If it is not then the NSS MPI will be compiled.
4109 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4111 * Merged a long nickname (127 characters long) crash bugfix from
4112 Irssi CVS tree. Affected file irssi/src/core/misc.c.
4114 * Merged a freed memory reference bugfix from Irssi CVS tree.
4115 Affected file irssi/src/core/commands.c.
4117 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4119 * Added the server's public key sving and verification to the
4120 server when performing the SKE. This was missing and the
4121 remote server's (or router's) public key was accepted without
4122 checking whether we have it previously or trust it at all.
4123 Affected file silcd/protocol.c.
4125 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4127 * Check in the silc_server_timeout_remote if protocol is active
4128 and make sure that the protocol's final callback is called so
4129 that all memory if freed. Affected file silcd/server.c.
4131 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * silc_server_whois_send_reply crashed the server if the nickname
4134 was 127 characters long. Affected file silcd/command.c.
4136 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Added sanity check to the silc_server_new_client. If the hostname
4139 is provided inside username then check that the provided hostname
4140 really is the same as the resolved one. If the hostname was not
4141 resolved then check it from the public key. Affected file is
4142 silcd/packet_receive.c.
4144 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
4145 if the server disconnected us and the connection is not valid
4146 anymore. Affected file irssi/src/silc/core/silc-channels.c.
4148 * Moved the silc_client_[chmode|chumode|chumode_char] away from
4149 the library to the lib/silcutil/silcutil.[ch].
4151 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Close log file after open. Affected file
4154 lib/silcutil/silclog.c.
4156 * Check whether sock == NULL in silc_client_send_packet and return
4157 if it is. Affected file lib/silcclient/silcclient.c.
4159 * Check rec->entry == NULL in the Irssi SILC Client before
4160 sending the channel message. Affecte file is
4161 irssi/src/silc/core/silc-servers.c.
4163 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4165 * Merged a splitted window bugfix from Irssi CVS tree. The
4166 affected file is irssi/src/fe-text/textbuffer-view.c.
4168 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
4169 It did not print nickname.
4171 * Improved the distributions system a bit.
4173 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4175 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
4176 irssi/src/fe-text/gui-window.c.
4178 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
4179 to in-active server. The affected file is
4180 irssi/src/silc/core/client_ops.c.
4182 * Resolve the client in USERS command reply if the entry does
4183 not have username resolved. The affected file is
4184 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
4185 command to WHOIS command to really resolve stuff. The USERS
4186 is not used any more in any critical section so WHOIS can
4187 be used even though it might be slower than IDENTIFY.
4189 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
4192 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4194 * Changed the protocol API a bit more consistent in the
4195 lib/silccore/silcprotocol.[ch].
4197 * Changed the following headers to ROBODoc format:
4199 lib/silccore/silcpayload.h
4200 lib/silccore/silcprotocol.h
4201 lib/silccore/silcsockconn.h
4203 All core library headers are now formatted.
4205 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4207 * Fixed a bug in Irssi SILC client; do not show that you are
4208 server/router operator if you really are not. Affected file is
4209 irssi/src/silc/core/client_ops.c.
4211 * Renamed silc_command_free_payload to silc_command_payload_free.
4212 Affected file lib/silccore/silccommand.h
4214 * Added silcmath.h to include the prototoypes of various routines
4215 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
4218 * Changed the following headers to ROBODoc format:
4220 lib/silccore/silcchannel.h
4221 lib/silccore/silccommand.h
4222 lib/silccore/silcid.h
4223 lib/silccore/silcidcache.h
4224 lib/silccore/silcmode.h
4225 lib/silccore/silcnotify.h
4226 lib/silccore/silcpacket.h
4227 lib/silcmath/silcmath.h
4229 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Added checking to the server code not to start the server if
4232 ciphers and stuff are not configured properly. Affected files
4233 silcd/serverconfig.[h] and silcd/server.c.
4235 * Changed the layout of the header files of the public interfaces
4236 in the SILC libraries. The new layout supports ROBODoc
4237 documentation tool (and some others) so that it is easy to create
4238 a library reference manual. All the other headers and source
4239 code must still follow the CodingStyle document. Also source
4240 code must not include these ROBODoc stuffs, only the headers.
4241 Furthermore, all public interface headers must now be named
4242 by using `silc' prefix, example: silcapi.h, silccipher.h.
4243 Some files were renamed due to this. All the other headers
4244 must not be used as public interfaces. I will update the
4245 CodingStyle document later. Changed following headers, so far:
4247 lib/silcclient/silcapi.h
4248 lib/silccore/silcauth.h
4249 lib/silccore/silcprivate.h
4250 lib/silccrypt/silcdh.h
4252 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4256 * Removed silc_client_packet_send_flush from the client library
4257 as it is not needed. Affected file lib/silcclient/client.[ch].
4259 * Added printing of message of unresolved authentication method
4260 to the Irssi SILC client. Added it to the module formats.
4261 Removed the same message from the client library.
4263 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * Added new distribution feature, DISTLABEL. Every distribution
4266 can define own preprocessor label that can be used in the
4267 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
4268 file distributions, acconfig.h.pre and prepare.
4270 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4272 * Added Makefile.defines_int to include the actual definitions
4273 for Makefile.defines.in. Tested the new distribution system,
4274 created distributions and tested installation.
4276 * Added AWAY message printing to the Irssi SILC client. Added
4277 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
4279 * Added SCONNECT command to call the SILC's CONNECT command.
4280 Cannot use CONNECT directly since Irssi uses that internally.
4281 Affected file irssi/src/silc/core/silc-servers.c.
4283 Added ACTION local command. It is same as ME command but takes
4284 the channel as mandatory argument.
4286 Rewrote some of the Irssi's help files to suite for SILC
4289 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * Added Makefile.defines[.in] that should for now on be included
4292 in all Makefile.am file in the source tree. That file includes
4293 all common compilation definitions for SILC source tree.
4295 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4297 * Minor changes to the ./prepare script to change the package
4298 name according the distribution name to the configure.in.
4300 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4302 * Created new distribution system. Added file `distributions'
4303 that defines all the distributions that can be created out of
4304 the SILC source tree. The ./prepare script now reads that
4305 file to determine how to prepare the distributions. The
4306 first argument to the ./prepare is the name of the distribution
4307 and second is the version of the distribution. If given
4308 without arguments it creates the default (toolkit) distribution
4309 with the default version (defined in ./prepare).
4311 All Makefile.am files that are subject to the distributions
4312 are now named as Makefile.am.pre. These are ./Makefile.am
4313 and lib/Makefile.am. Others may be changed later.
4315 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4317 * Added invite list, ban list, some key management and connection
4318 error message printing to module formats in the Irssi SILC client.
4320 * Added new silc_client_set_away_message to set the away message
4321 that is back to the person who sent private message. The
4322 affected file lib/silcclient/silcapi.h and the
4323 lib/silcclient/client_prvmsg.c.
4325 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4327 * Fixed the private message sending in the Irssi SILC client,
4328 added local command KEY to the Irssi SILC client.
4330 Added key management and key agreement message formats to the
4331 irssi/src/fe-common/silc/module-formats.[ch].
4333 Added USERS (alias WHO) printing, server/router operator
4334 indication and LIST command printing to the module formats.
4336 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4338 * Fixed channel joining notify handling, cumode notify handling
4339 from Irssi SILC client.
4341 * Added SILC specific module-formats to the Irssi SILC client so
4342 that SILC specific message hilighting, colors etc is possible.
4343 Affected file irssi/src/fe-common/silc/module-formats.[ch].
4345 Added channel mode, channel user mode, actions, notices,
4346 whois and whowas printing to the the module-formats.c.
4348 * Fixed a bug in channel deletion in the server. The channel
4349 is not left to the cache even if the channel founder auth mode
4350 is set when there are no users anymore on the channel. Affected
4351 file silcd/server.c.
4353 * The silc_net_localhost now resolves the entire hostname including
4354 the domain name. Affected file lib/silcutil/silcnet.c.
4356 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4358 * Changed the ask_passphrase client operation to be ascynchronous.
4359 It has now a completion callback and a context that the
4360 application must call after it has got the passphrase from
4361 the user. Affected files lib/silcclient/silcapi.h,
4362 lib/silcclient/protocol.c, lib/silcclient/command.c and
4365 Added SilcAskPassphrase callback that the application calls
4366 to deliver the passphrase to the library.
4368 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4369 The public key verification and especially a certificate
4370 verification is asynchronous procedure.
4372 Added new SILC_SKE_STATUS_PENDING status to indicate the
4373 request is pending and a callback will be called to finalize
4376 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4377 indicate that remote end did not send its public key (or
4378 certificate), even though we require it. Added check for this
4379 condition in the SKE. This was a security bug, now fixed.
4381 Defined new SilcSKEVerifyCbCompletion callback that is called
4382 when the verification process is completed.
4384 The affected files lib/silcske/silcske_status.h and
4385 lib/silcske/silcske.[ch].
4387 * Changed the verify_public_key client operation to be async
4388 as well. Defined SilcVerifyPublicKey callback that is used to
4389 indicate the success of the public key verification process.
4391 Changed the server and client to use the new async client
4394 * Changed the Irssi SILC client's internal scheduler to be called
4395 twice as many times as it used to be. As a result the client
4396 should be a bit faster now. Affected file is
4397 irssi/src/silc/core/silc-core.c.
4399 * Added support to Irssi SILC client of asynchronous public key
4400 verification and passphrase inquiry. Affected file is
4401 irssi/src/silc/core/silc-core.c.
4403 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4405 * Do not say "You have left channel %s" in client library.
4406 Moved it to the application. Affected files are
4407 lib/silcclient/command.c and silc/client_ops.c.
4409 * Fixed silc_client_get_clients. Command context was not
4410 duplicated and was freed memory in the callback. Affected
4411 file lib/silcclient/idlist.c.
4413 * Do not say "you are now talking..." on JOIN command in the
4414 client library. The appliation must handle it.
4416 * Do not say ".. changed topic to" in command reply in the
4417 client libary. The application must handle it.
4419 * Fixed TOPIC command sending in the client library.
4421 * Fixed a memory leak in silc_client_command_free in the file
4422 lib/silcclient/command.c.
4424 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4426 * Imported a modified version of Irssi client to the source tree.
4427 The Irssi will be used to create a new client called
4428 Irssi SILC. Imported to irssi/.
4430 Added silc_core_init_finish function to the Irssi. Affected
4431 file irssi/configure.in.
4433 A lot changes in the Makefile.ams around the irssi tree.
4435 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4437 * Do not rehash if the new size is same as the old size of the
4438 hash table, in the silc_hash_table_rehash*. The affected file
4439 lib/silcutil/silchashtable.c.
4441 * Replaced hash_table_del_by_context calls from the server
4442 (when channel->user_list and client->channels) to the
4443 hash_table_del as it is sufficient and faster.
4445 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4447 * Added silc_hash_table_list, silc_hash_table_get and the
4448 SilcHashTableList structure to provide an alternative way to
4449 traverse the hash table. The affected files are
4450 lib/silcutil/silchashtable.[ch].
4452 * Changed the server's idlist routines to use the hash table
4453 routines to optimize the code.
4455 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4457 * Replaced the client entry's `channel' list and channel entry's
4458 `user_list' list to hash tables for optimized lookup. Changed
4459 the code to use the hash table interface around the code.
4460 Affected file lib/silcd/idlist.[ch].
4462 * Added `auto_rehash' boolean argument to the function
4463 silc_hash_table_alloc to indicate whether the hash table should
4464 auto-rehash when it thinks is appropriate time. It will
4465 increase the hash table size if the there is twice as much
4466 entries in the table than the size of the table, and will
4467 decrease the size if there are twice as less entries than
4468 the size of the table.
4470 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4472 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4474 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4476 * silc_idcache_purge_by_context deletes the entry now by context
4477 as it is supposed to do. Affected file lib/silccore/idcache.c.
4479 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4480 client is not anymore valid (WHOWAS givens the info) and not
4481 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4483 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4485 * Removed the `data' and `data_len' arguments from the ID Cache
4486 interfaces and added `name' argument. ID Cache does not handle
4487 anymore the binary data only a names associated with given ID.
4489 * When hashing a Client ID with silc_hash_id the entire ID is
4490 not hashed anymore, instead only the hash of the Client ID is
4491 hashed. This way we can access the Client ID from the cache
4492 with Client ID but with the hash of the ID (which is a hash of
4493 the nickname) as well without any difference in performance.
4495 Added also silc_idcache_find_by_id_one_ext to do one on one
4496 searching when we have the actual ID. Added also function
4497 silc_hash_client_id_compare. The affected files are
4498 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4500 * When hashing the name associated with a ID it is always done
4501 in lowercase. This way we can access the cache without worrying
4502 about case-sensitivity, even though, for example nicknames are
4505 * Fixed a bug in server with channel message sending. It put
4506 wrong ID type as destination ID. The affected file
4507 silcd/packet_send.c.
4509 * silc_idcache_del_by_context now deletes from all hash tables
4510 by context. Affected file lib/silccore/idcache.c.
4512 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4514 * Changed the client library to use the new ID Cache interface.
4515 Changes around the source tree.
4517 * Added silc_hash_table_rehash_ext to rehash with specific
4518 hash function. Affected file lib/silcutil/silchashtable.[ch].
4520 * Added silc_hash_string_compare to compare two strings in the
4521 hash table. Affected file lib/silcutil/silcutil.[ch].
4523 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4525 * Added new function silc_idcache_del_by_context into the
4526 lib/silccore/idcache.[ch].
4528 * Changed the server's ID list routines to use the new ID Cache
4529 interface. Changes around the source tree.
4531 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4533 * Added silc_hash_table_del[_by_context]_ext functions in to the
4534 lib/silcutil/silchashtable.[ch].
4536 Removed silc_hash_table_find_all* routines and added new
4537 silc_hash_table_find_foreach to replace them.
4539 Added silc_hash_table_replace_ext function as extended
4540 replacing function. Separated the simple hash table interface
4541 from the extended hash table interface in the file
4542 lib/silcutil/silchashtable.h.
4544 * Fixed minor bugs and changed it to use some of the new
4545 hash table functions in lib/silccore/idcache.c
4547 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4549 * Added new function silc_hash_table_find_all to return all keys
4550 in the hash table by the specified key. As the hash table is
4551 collision resistant it also makes it possible to have several
4552 duplicate keys in the hash table. This function may be used to
4553 find all of the keys from the hash.
4555 Added user_context arguments to the SilcHashFunction,
4556 SilcHashCompare and SilcHashDestructor to deliver user specified
4559 Added new fuctions silc_hash_table_find[_all]_ext to do
4560 extended lookup with specified hash and compare functions and
4561 specified user contexts.
4563 Added new function silc_hash_table_add_ext to add the key
4564 with specified hash function and user context.
4566 Added new function silc_hash_table_foreach to traverse all
4567 entrys in the hash table. Added SilcHashForeach callback
4570 Added new function silc_hash_table_del_by_context to delete
4571 the entry only if the context associated with the key matches.
4573 Affected files are lib/silcutil/silchashtable.[ch].
4575 * Removed silc_hash_[server/client/channel]_id and added just
4576 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4577 silc_hash_id_compare to compare two ID's using as the hash table
4578 comparison function. Added also silc_hash_data to hash
4579 binary data and silc_hash_data_compare to compare it.
4581 * Removed silc_idlist_find_client_by_hash as it is not needed
4582 anymore. Affected file silcd/idlist.[ch].
4584 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4585 to use internally the SilcHashTable. The new ID Cache is a lot
4586 faster than the old one. Some of the ID Cache interface was also
4587 rewritten and obsolete and stupid functions were removed.
4589 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4591 * Added entry_count field to the SilcHashTable to keep the number
4592 of the entries in the table. Implemented the function
4593 silc_hash_table_rehash. Added new function
4594 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4596 Fixed a minor bug in silc_hash_table_free.
4598 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4599 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4600 into the lib/silcutil/silcutil.[ch].
4602 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4604 * Implemented a collision resistant hash table into the
4605 lib/silcutil/silchashtable[ch]. See the header and the source
4606 for the SilcHashTable API.
4608 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4610 * Merged dotconf version 1.0.2 into lib/dotconf.
4612 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4614 * Do not compile anything in lib/silcsim/* if the SIM support
4615 is not enabled. The tree should now compile without problems
4618 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4620 * Compiled the SILC under cygwin. Compiled and tested briefly
4621 without problems. More tests needed. The SIMs didn't compile
4624 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4626 * Fixed possible crash in silc_get_username in the
4627 lib/silcutil/silcutil.c.
4629 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4631 * Fixed a va_arg in silc/client_ops.c.
4633 * Oops, RC5 routines were named AES and caused some problems
4634 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4636 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4638 * Added new SilcIDIP structure into the lib/silccore/id.h and
4639 replaced the old `ip' fields from all SILC ID's to that type.
4640 This is a step towards IPv6 support.
4642 The silc_id_get_len takes now the ID as an extra argument.
4643 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4644 both IPv4 and IPv6 based ID's.
4646 The affected files are lib/silccore/id.[ch] and other files
4647 around the tree using these routines.
4649 * Removed the ID length arguments in server from various
4650 silc_server_send_notify_* routines -> they are not needed
4653 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4655 * Fixed memory leak in silc_encode_pem_file in the file
4656 lib/silcutil/silcutil.c.
4658 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4660 * Check minor version as well in the SKE. Affected files are
4661 silcd/protocol.c and lib/silcclient/protocol.c.
4663 * Added --identifier option to the server so that an identifier
4664 can be when creating the public key for the server. Affected
4665 file is silcd/silcd.c.
4667 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4668 lib/silccrypt/silcpkcs.c.
4670 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4672 * Register default ciphers and stuff when using -C option with
4673 the server. Affected file sildc/silcd.c.
4675 * Put back the servers public key filename format, it is better
4676 than the new one. For now, the client keys are saved with the
4677 new filename format. The affected file silc/client_ops.c.
4679 * Implemented the Cipher API for the rest of the ciphers that
4680 did not implement it or implemented it the wrong way.
4682 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4684 * Register default ciphers and stuff when using the -S option
4685 in the client. Affected file silc/silc.c. Same also when
4686 creating new key pair with -C option.
4688 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4690 * Fixed the silc_verify_public_key client operation function to
4691 save the public keys differently. The fingerprint is now
4692 used as filename and not the hostname. This way also the
4693 client keys are saved uniquely and not with hostnames. The
4694 affected file is silc/client_ops.c.
4696 * Trimmed the silc_hash_fingerprint function to remove extra
4697 whitespaces from the end of the fingerprint. The affected
4698 file is lib/silccrypt/silchash.c.
4702 * Added silc_cipher_register_default function to register all
4703 default ciphers. It can be used when configuration files
4704 does not exist and the application does not want any specific
4705 ciphers in any specific order.
4707 The SilcDList is now used as silc_cipher_list dynamically
4708 allocated cipher list. Removed the static list all together
4709 and now all ciphers must be allocated to the dynamic list.
4710 The silc_cipher_alloc routine was changed to check only the
4713 All silc_cipher_* routines that used to return int returns
4716 The affected files lib/silccrypt/silccrypt.[ch].
4718 * The same thing was done to silc_hash_* as for silc_cipher_*
4719 routines. Affected files lib/silccrypt/silchash.[ch].
4721 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4722 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4723 Added also silc_pkcs_[un]register[_default] functions.
4724 Removed the data_context from the PKCS API.
4726 * Added silc_hmac_register_default function to register default
4727 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4728 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4729 to unregister all hmacs at once.
4731 * Register the default ciphers, hash functions, PKCSs and HMACs
4732 if client's configuration file does not exist. The affected
4735 * The client did not load the hash functions from the SIM
4736 modules at all. Added support for this. Affected file is
4737 silc/clientconfig.c.
4739 * When decoding public key with silc_pkcs_public_key_decode, check
4740 the supported algorithm only if PKCS are registered. Affected
4741 file lib/silccrypt/silcpkcs.c. The same was done with the
4742 silc_pkcs_private_key_decode.
4744 * Fixed the SILC List routines to keep the list always in order.
4745 It used to change the list's order when traversing the list but
4746 not it preserves the order. Affected file lib/trq/silclist.h.
4748 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4750 * Added the client library to use the SilcSocketConnection's
4751 reference counter (by silc_socket_dup) to prevent the bug that
4752 the socket object may be freed underneath async operation.
4754 * The name resolv library checking fixes in the configure.in.pre.
4757 * Created new version of the protocol drafts for future
4758 development. The -03 drafts are the ones that will be changed
4759 in the trunk now and the -02 will remain as they are.
4761 * Send list of CUMODE notifys to the router when announcing
4762 the channel users to the router. Affected file silcd/server.c.
4763 If the router receiving channel founder CUMODE for a channel
4764 that already has channel founder it will send CUMODE notify
4765 to the sender to remove the channel founder rights from the
4766 announced client. Affected file silcd/packet_receive.c.
4768 * The CUMODE notify may now use Server ID as well as the entity
4769 who changes the mode. Updated protocool specs.
4771 * Updated INSTALL and README files.
4773 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4775 * New web pages in the http://silc.pspt.fi. The pages was
4780 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4782 * Implemented the [DenyConnectin] config section in the server.
4783 Added silc_server_config_denied_conn to check whether incoming
4784 connection is denied. Affected file silcd/serverconfig.[ch].
4786 * Do not check the ports when checking the incoming configuration
4787 data if the port is 0, meaning any. Affected file is
4788 silcd/serverconfig.c.
4790 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4792 * Fixed buffer overflow in silc_string_compare in the file
4793 lib/silcutil/silcutil.c.
4795 * Fixed double free in silc_server_command_leave in the file
4798 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4800 * Fixed the version checking in the server. Affected file is
4803 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4805 * Fixed the configuration data fetching when accepting new
4806 connections in the server. Affected file silcd/server.c.
4808 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * Added `sender_entry' argument to the function
4811 silc_server_packet_relay_to_channel so that we can check
4812 whether some destination actually belongs to the same route
4813 the sender belongs (ie, we must not resend the packet to the
4814 sender). Affected file silcd/packet_send.[ch].
4816 * Added `servername' field to the SilcClientEntry in the server
4817 to hold the name of the server where client is from. Affected
4818 file is silcd/idlist.h.
4820 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4822 * Moved the channel message encrypting in the router betwen
4823 router connections from silc_server_channel_message to the
4824 silc_server_packet_relay_to_channel since we want to check
4825 whether we have anybody channel before encrypting anything.
4826 Affected files silcd/packet_[receive/send].c.
4828 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4830 * Fixed the [AdminConnection] server config section to support
4831 multiple entries. Affected file silcd/serverconfig.c.
4833 * Added support into the server to check the validity of the
4834 incoming connection before executing any KE or authentication
4837 * The connection configuration is now saved to the KE and
4838 connection auth protocol contexts and not fetched anymore in
4839 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4841 * The local hosts listenning address and port is also resolved
4842 now when starting the server. We want to have the socket object
4843 to include the real address and port for the listener. Added
4844 new function silc_net_check_local_by_sock into the files
4845 lib/silcutil/silcnet.[ch].
4847 * Fixed a broadcast bug in server -> do not broadcast if we
4850 * Fixed a routing bug. Do not route broadcast packets ever.
4851 Broadcast packets must be processed always and not routed since
4852 they may be destined to some other host than yourself and thus
4853 would get routed without no good reason. Affected file is
4856 * Added function silc_server_config_is_primary_route to check
4857 whether primary router connection has been configured (a router
4858 configuration that we are initiating). If there is not, we
4859 will assume that there is only two routers in the SILC network
4860 and we will use the incoming router connection as our primary
4861 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4863 * Changed the order of the broadcasting. Broadcast _after_ the
4864 packet has been processed not before. Affected file is
4867 * Fixed a [ClientConnection] parsing bug. The port was never
4868 parsed correctly thus resulting to port 0. Affected file
4869 silcd/serverconfig.c.
4871 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4872 argument and did not set the broadcast packet flag. Affected
4873 file silcd/packet_send.c. Fixed same bug in the function
4874 silc_server_send_notify as well.
4876 * If we receive NEW_ID packet for our own ID in the server, ignore
4879 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4883 * Removed the nickname from the Private Message Payload.
4884 Updated the code and the protocol specs.
4886 * Updated protocol specs for submitting to the IETF.
4888 * Tweaked the Random Number Generator a bit. Affected file
4889 lib/silccrypt/silcrng.c. Exported a new function
4890 silc_rng_[global]_add_noise which can be used to add more
4893 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4895 * Do not parse packets with different timeout when protocol
4896 is active -> may cause problem with rekey. Affected file
4899 * When server receives signoff notify it must not create
4900 new channel key if the client is on any channels since the
4901 sender of the signoff notify will create it.
4903 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4905 * Added printing of error messages during SKE protocol from the
4906 failure packet sent by server during SKE. Affected file
4909 * Removed the client's failure_callback handling with timeout
4910 and handle it immediately when received.
4912 * The SKE library returned wrong type in SUCCESS and FAILURE
4913 packets. They must be 32 bit MSB not 16 bit MSB.
4915 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Ok, rewrote the logic of the re-key and now it seems to work.
4918 I tested it on high traffic with frequent re-keys without
4919 problems. Added hmac_receive (and renamed hmac to hmac_send)
4920 in SilcClientConnection in lib/silcclient/client.h and
4921 in SilcIDListData in silcd/idlist.h. Also, removed the
4922 SilcPacketParserContext's cipher and hmac fields as they are
4923 not needed anymore and actually caused some problems when
4924 the ciphers and hmac's changed underneath the packet parser.
4926 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * If re-key protocol is active then process the incoming packets
4929 synchronously since we must assure that icoming packets encrypted
4930 with the old key is processed before the new keys is set to
4931 use. This is true other packets than for REKEY packets.
4932 Affected file silcd/server.c. The same was done to client library
4933 as well, affected file lib/silcclient/client.c.
4935 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4937 * Fixed bug in client and server to accept the force send if
4938 the packet is send from silc_[server/client]_packet_process
4939 function. Otherwise the packets are never delivered, oops.
4941 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4943 * Disable force sending of packets when REKEY protocol is active.
4944 We must assure that no packet is sent directly when rekey is
4945 performed. All packets must be sent through packet queue.
4946 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4947 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4948 function is silc_[server/client]_packet_send_real to check
4951 * Replaced the SIM paths from example config files to
4952 /usr/local/modules. Also, make install creates now
4953 /usr/local/silc/logs directory to hold all the SILC server
4956 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4958 * Made the configure.in.pre work on Solaris. Patch by salo.
4960 * Made all ciphers compatible with non-x86 machines. Defined
4961 CBC mode macros into lib/silccrypt/ciphers_def.h.
4963 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4965 * Fixed the make install.
4967 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * When MAC computation fails the silc_packet_decrypt returned 0
4970 even though it was supposed to return -1. Fixed this. The
4971 affected file is lib/silccore/silcpacket.c.
4973 * Do not replace the config files in /etc/silc (in make install)
4974 if they already exist. Affected file ./Makefile.am.
4976 * Do not send re-key packets immediately but through packet queue.
4977 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4979 * Changed silc_net_check_host_by_sock to return FALSE if the
4980 IP/DNS could not be resolved. Though, it returns the IP address
4981 now even if it could not resolve it (but returns also FALSE).
4982 Affected file lib/silcutil/silcnet.[ch].
4984 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Added silc_pkcs_decode_identifier to decode the public key's
4987 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4988 Added also silc_pkcs_free_identifier. Added also new context
4989 SilcPublicKeyIdentifier.
4991 * Added -S option to the silc client. It is used to dump the
4992 contents of the specified public key file.
4994 * Changed the PKCS api to return the public key length when
4995 setting the public key.
4997 * Fixed a fatal bug in the public and private key file loading.
4998 Affected file lib/silccrypt/silcpkcs.c.
5000 * Execute the packet parsing for client with zero (0) timeout
5001 if the protocol is active. Affected file silcd/server.c.
5003 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5005 * Made the key generation options to the silcd program. Added
5006 -C option, equivalent to client's option.
5008 * Added new [ServerKeys] config section to the server. It
5009 configures the server's public and private key.
5011 * Defined generic Public Key Payload into the protocol
5012 specification to send specific type of public keys and
5015 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
5016 public key or certificate.
5018 * Implemented the GETKEY command to the server and to the
5019 client library and on user interface.
5021 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5023 * Made preliminary `make install' work.
5025 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5027 * Added SilcServerRekey context into silcd/idlist.h.
5029 * Added the PFS support as defined in the specification to the
5030 SKE protocol. Affected files lib/silcske/*.c.
5032 * Added `ske_group' field to the SilcServerRekey context to hold
5033 the number of the SKE group that is used with PFS in re-key.
5034 Affected file silcd/idlist.h.
5036 * Added PFS re-key support to the server. Affected file is
5039 * Added silc_protocol_cancel to cancel execution of the next
5040 state of the protocol. Affected file is
5041 lib/silccore/silcprotocol.[ch].
5043 * Added the re-key support with and without PFS to the client
5044 library. Re-key is performed once in an hour, by default.
5046 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
5047 Added silc_client_rekey_callback and silc_client_rekey_final.
5048 Affected files are lib/silcclient/protocol.[ch] and
5049 lib/silcclient/client.[ch].
5051 * Removed the `hmac_key' and `hmac_key_len' fields from the
5052 SilcClientConnection structure; not needed. Affected file is
5053 lib/silcclient/client.h.
5057 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Do not ask whether user wants to use the negotiated private key
5060 for private messages, just use it. Affected file is
5061 silc/local_command.c.
5063 * Added `send_enc_key' and `enc_key_len' fields to the
5064 SilcIDListData structure since they are needed in the re-key
5065 phase. Affected file is silcd/idlist.[ch].
5067 * Implemented the simple re-key protocol into the server.
5068 Affected files silcd/server.c and silcd/protocol.[ch]. The
5069 re-key will be performed once in an hour, by default.
5071 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
5072 Added silc_server_rekey, silc_server_rekey_callback and
5073 silc_server_rekey_final.
5075 * Removed Tunneled flag from the protocol. Updated the code
5076 and the specifications.
5078 * Adde `pfs' field to the SilcIDListData to indicate whether
5079 the PFS is to be performed in the re-key. Affected file is
5082 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5084 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
5085 int64 of at least the xintXX size. If void * is less that 4
5086 bytes uint32 * will be used. Defined bool as boolean.
5088 * Changed _ALL_ unsigned long and unsigned int to uint32,
5089 unsgined short to uint16 in the source tree.
5091 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
5092 not handle clients that has entry->data.registered == FALSE.
5093 They are not in the network anymore. Affected file is
5096 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5098 * Implemented the sending of the SERVER_SIGNOFF notify in the
5099 server. Affected file is silcd/server.c.
5101 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
5102 Added also silc_notify_payload_encode_args into the
5103 lib/silccore/silcnotify.[ch].
5105 * Implemented ther SERVER_SIGNOFF notify handling in the server.
5106 Affected file silcd/packet_receive.c.
5108 * Implemented the SERVER_SIGNOFF notify handling in the client
5109 library. Affected file lib/silcclient/client_notify.c. Also,
5110 implemnted the printing of the SERVER_SIGNOFF info to the
5111 application. Affected file silc/client_ops.c.
5113 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
5114 if the deleting was successful. Affected file silcd/idlist.[ch].
5116 * Added support for public key authentication in the connection
5117 authentication protocol in the client library. Affected file
5118 lib/silcclient/protocol.c.
5120 * Changed the server's silc_idlist_get_clients_by_* interface
5121 to support already allocated array so that new entries may be
5122 added to pre-allocated array. Affected file silcd/idlist.[ch].
5123 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
5124 and command replies.
5126 * All command reply functions in the server now calls the
5127 pending command callback even if error occured. This way the
5128 error will be delivered to the client as well. Affected files
5129 silcd/command.c and silcd/command_reply.c.
5131 * Fixed INFO command to return local server's info if no server
5132 was provided. Affected file lib/silcclient/command.c.
5134 * Removed RESTART command for good. Updated the code and the
5137 * Rewrote parts of the task system. It is a bit simpler now.
5138 Removed unsued task priorities. The affected files are
5139 lib/silcutil/silctask.[ch].
5141 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5143 * Moved the USERS printing from the library to the application.
5144 Affected files lib/silcclient/command.c and silc/client_ops.c.
5146 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5150 * Added channel key re-key support. The re-key is perfomed
5151 only by the router and is done once in an hour. Added `rekey'
5152 field to the SilcChannelEntry in the server. Affected files
5153 silcd/server.c and silcd/idlist.h.
5155 * Added silc_task_unregister_by_context into the file
5156 lib/silcutil/silctask.[ch].
5158 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5160 * Added SILC_UMODE_GONE mode to indicate when the client is not
5161 present in the SILC network. Added also support to the local
5162 command AWAY that will set this mode. Added support of showing
5163 "xxx is gone" in WHOIS command. The USERS command shows the
5164 gone status as well.
5166 * Fixed setting server and router operator privileges in the
5167 server's UMODE command. Affected file silcd/command.c.
5169 * Merged the SKE KE1 and KE2 payloads into one payload. The
5170 new KE payload is equivalent to the old KE2 payload.
5172 Cleaned up the SKE Start Payload parsing. It now uses the
5173 simple buffer unformatting to do the parsing. A lot faster
5176 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
5177 to the SKE that is used to indicate whether both of the SKE
5178 parties should perform authentication. By default only the
5179 responder performs authentication. By setting this flag also
5180 the initiator must do authentication. By default it is unset
5181 since in normal SKE case, client to server connection, only
5182 the responder should do authentication. When doing SKE between
5183 two clients both should perform authentication. Updated the
5184 code and the protocol specs.
5186 * A little fix to IDENTIFY command in the server. Search the
5187 client first by hash not nickname. Affected file is
5190 * Fixed the silc_client_close_connection to support closing
5191 the client to client connections wihtout deleting too much
5192 data. Affected file lib/silcclient/client.c.
5194 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
5195 are received if protocol used to be active but is not anymore
5196 the application would crash due to NULL pointer dereference.
5197 Affected files silcd/server.c and lib/silcclient/client.c.
5199 * Added `hash' field to the SilcClientConnection to include
5200 the hash function negotiated in the SKE protocol.
5202 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
5203 to set the channel founder authentication data. A client can
5204 claim the founder rights later by providing the authentication
5205 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
5206 This way the channel founder can regain the channel founder
5207 privileges even it is left the channel. This works only on
5208 local server and the client must be connected to the same
5209 server to be able to regain the founder rights. Updated the
5210 protocol specs accordingly.
5212 Added support to the CMODE command in the client to set the
5213 founder auth data. Read the README to see how to set it.
5215 Added support to the CUMODE command to claim the founder
5216 rights. Read the README to see how to do it.
5218 Added support for the founder authentication to the Channel
5219 Entry in the server. Affected file silcd/idlist.h.
5221 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
5222 server's CMODE command. Affected file silcd/command.c.
5224 * Added the following new functions into lib/silccore/silcauth.[ch]:
5225 silc_auth_get_method and silc_auth_get_data.
5227 * The server now saves the remote hosts public key to the
5228 SilcIDListData pointer. Affected file silcd/protocol.c.
5230 * The normal server now does not remove the channel entry from
5231 the cache if the founder authentication data is set. It used
5232 to remove it if the founder was the last one on the channel on
5233 the server and left the channel. The auth data is saved and
5234 if the channel is re-joined later the old entry is used with
5235 the old auth data. Affected files silcd/command_reply.c and
5238 * Removed the `pkcs' field from the SilcIDListData structure
5239 in the server; it is not used. Affected file silcd/idlist.h.
5241 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5243 * Fixed packet processing on slow links. Partial packets were
5244 never re-processed because the incoming data buffer was cleared
5245 by the application. Application must not directly clear the
5246 sock->inbuf, the packet processing routines handle it. Fixed
5247 this in client library and in server.
5249 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5251 * Fixed the WHOIS and IDENTIFY send reply function to really
5252 check whether to send list or just one entry. Affected file
5255 * Cleaned up the LEAVE command's channel key distribution. The
5256 affected file silcd/command.c.
5258 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
5259 can enforce the channel mode as well. In that case the ID
5260 includes the ID of the server. The code now enforces the
5261 mode change if the router have different mode than the server.
5263 * The notify client operation with CMODE_CHANGE notify can now
5264 return NULL client_entry pointer if the CMODE was not changed
5265 by client. Application must check for this.
5267 * Added <Server ID> argument to INFO command to support server
5268 info fetching by Server ID.
5270 * Added silc_server_announce_get_channel_users to get assembled
5271 packets of channel users of the specified channel. Affected
5272 file silcd/server.[ch].
5274 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
5275 was freed underneath the ID Cache.
5277 * Re-announce clients when the server received CHANNEL_CHANGE
5278 notify from the router. Affected file silcd/packet_send.c.
5280 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5282 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
5283 crashed since it did not handle the fact that there is no cipher
5284 called "3" and didn't check the error condition. Now fixed.
5286 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
5287 flag. It can be used to send message requests.
5289 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5291 * Implemented the RESTART command in the client.
5293 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
5294 notice type messages. Added notice printing to the user
5297 * The channel keys are not re-generated if the channel's mode
5298 is PRIVKEY, ie private key on the channel exists. Affected
5299 files silcd/server.c and silcd/command.c.
5301 * Fixed a little bug in channel message delivery when channel
5302 private keys are set in the server. Affected file is
5303 silcd/packet_send.c.
5305 * Changed the setting on channel->on_channel = TRUE from the
5306 silc_client_save_channel_key to the JOIN command reply. The
5307 key payload is not received if the private channel key is set.
5308 Affected file lib/silcclient/command_reply.c and the
5309 lib/silcclient/client_channel.c.
5311 * When the CMODE_CHANGE notify is sent and the channel private
5312 key mode is removed the channel key must be re-generated in
5313 other cells as well. Added this support for the router in the
5314 silcd/packet_receive.c.
5316 * Added new local command NOTICE to send notice message on
5317 channel. Affected file silc/local_command.[ch].
5319 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5321 * Added new local command ME to the client. It is used to send
5322 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
5323 some action. Affected file silc/local_command.[ch].
5325 * Changed channel_message and private_message client operations
5326 to deliver the message flags to the application. Added also
5327 the `flags' arguments to the silc_client_send_channel_message
5328 and silc_client_send_private_message functions. Affected file
5331 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5333 * Redefined the Private Message Payload to support private message
5334 keys and to support the new private message flags. Updated
5335 the protocol specs. Flags makes it possible to have for example
5336 CTCP style messages.
5338 * Added new type SilcPrivateMessagePayload and defined an API
5339 for it in the lib/silcclient/silcprivate.[ch].
5341 * Tested private message private keys successfully. Tested the
5342 private message key set, unset and list commands with the new
5345 * Redefined the Channel Message Payload to include the channel
5346 message flags (equal with private message flags) to support
5347 for example CTCP style messages.
5349 * Defined some of the message (for channel and private message)
5350 flags. Updated the protocol specs and added the flags to the
5351 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5353 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5355 * Added SilcKeyAgreementStatus type to the key agreement routines
5356 to indicate the current status and error if one occured.
5357 The status types are defined in the lib/silcclient/silcapi.h.
5359 * Added new local command KEY that is used to set and unset private
5360 keys for channels, set and unset private keys for private messages
5361 with remote clients and to send key agreement requests and
5362 negotiate the key agreement protocol with remote client. The
5363 key agreement is supported only to negotiate private message keys,
5364 it currently cannot be used to negotiate private keys for channels,
5365 as it is not convenient for that purpose.
5367 * Fixed a minor pending callback setting bug in the function
5368 silc_client_get_client_by_id_resolve, now the function works.
5369 Affected file lib/silcclient/idlist.c.
5371 * Added function silc_net_get_local_port to get local bound
5372 port by socket. Added to lib/silcutil/silcnet.[ch].
5374 * Added `sockets' and `sockets_count' fields to the SilcClient
5375 object. They hold the sockets of the listenning sockets in
5376 the client. Listenning sockets may be for example the key
5377 agreement server. Affected file lib/silcclient/client.[ch].
5378 Added functions the silc_client_add_socket and the
5379 silc_client_del_socket. They are exported to the application
5382 * Added ~./silc/clientkeys to support other client's public keys.
5384 * Renamed verify_server_key client operation to verify_public_key
5385 and added one argument to indicate the type of the connection
5386 (server, client etc.).
5388 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5390 * Added silc_server_connection_auth_request to handle the
5391 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5392 silcd/packet_receive.[ch].
5394 * Added silc_server_send_connection_auth_request into the
5395 silcd/packet_send.c to send the connection auth request packet.
5397 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5400 * Fixed the public key authentication in responder side in the
5401 server. The `auth_data' pointer includes the SilcPublicKey
5402 not the path to the public key. Affected file silcd/protocol.c.
5404 * Implemented the public key authentication in the initiator side
5405 in the server. Affected file silcd/protocol.c.
5407 * Removed the [RedirectClient] config section from the server
5408 configuration. Is not needed and I don't want to implement it.
5410 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5412 * Cleaned up the CMODE command in the server. It now works
5413 correctly and supports all the modes defined in the protocol.
5414 Affected file is silcd/command.c.
5416 * Added `hmac_name' field to the SilcChannelEntry in the server
5417 to hold the default HMAC of the channel. It can be set when
5418 creating the channel (with JOIN command). Affected files
5421 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5422 type to indicate the change of the current cipher and hmac
5423 on the channel. Client can safely ignore the <cipher> argument
5424 (if it chooses to do so) since the CHANNEL_KEY packet will
5425 force the channel key change anyway. The <hmac> argument is
5426 important since the client is responsible of setting the new
5427 HMAC and the hmac key into use.
5429 * Fixed the CMODE command in the client library as well.
5431 * Tested CMODE command in router environment successfully.
5433 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5435 * Show the version of the remote client (or server) when connecting
5436 to the server. It is logged to the log file. Affected file
5437 is silcd/protocol.c.
5439 * Fixed the KILLED notify handling in the client library. The
5440 client must be removed from all channels when receiving the
5443 Also, do not remove the client entry when giving the KILL
5444 command but when the KILLED notify is received.
5446 * Removed silc_idlist_find_client_by_nickname from the server.
5447 Not needed anymore. Affected files silcd/idlist.[ch].
5449 * Implemented the CHANNEL_CHANGE notify type handling to the
5450 server. Affected file silcd/server.c.
5454 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5456 * Added silc_server_send_notify_invite to send the INVITE
5457 notify between routers.
5459 * Implemented the INVITE command correctly to the server.
5461 * Implemented the INVITE notify type handling in the server.
5463 * Implemented the INVITE command to the client library and on the
5466 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5468 * Added function silc_server_get_client_resolve to find the
5469 client entry by ID from all ID lists and then resolve it
5470 (using WHOIS) if it cannot be found. Affected file is
5473 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5475 * Implemented the BAN command to the client library.
5477 * The JOIN command in the server now checks the invite list
5480 * Changed the silc_command_reply_payload_encode_va and the
5481 silc_command_payload_encode_va to support that if argument is
5482 NULL it ignores and checks the next argument. Affected file
5483 lib/silccore/silccommand.c.
5485 * Added silc_server_send_notify_ban to send the BAN notify
5486 type between routers.
5488 * Chaned the silc_notify_payload_encode to support that if
5489 argument is NULL it ignores and checks the next argument.
5490 Affected file lib/silccore/silcnotify.c.
5492 * Tested ban lists in router environment successfully.
5494 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5496 * Implemented BAN command to the server, in silcd/command.[ch].
5498 * Removed the BAN and INVITE_LIST modes from the CMODE command
5501 * Added function silc_string_match to regex match two strings.
5502 Affected files lib/silcutil/silcutil.[ch].
5504 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5506 * Redefined parts of the SilcChannelEntry in the server to support
5507 the new ban and invite lists.
5509 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5511 * Redefined the INVITE command. The same command can be used to
5512 invite individuals to the channel but also to manage the invite
5513 list of the channel (to add to and remove from the invite list).
5514 Updated the protocol specs.
5516 * Added new command SILC_COMMAND_BAN that can be used to manage
5517 the ban list of the channel. Updated the protocol specs.
5519 * Removed the channel modes: the SILC_CMODE_BAN and the
5520 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5521 in the CMODE command. The equivalent features are now available
5522 using INVITE and BAN commands. Updated the protocol specs.
5524 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5525 in the network about change in the current ban list. The notify
5526 type is not used by the client.
5528 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5529 support the invite lists.
5531 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5533 * Added new function silc_string_regexify that converts string
5534 including wildcard characters into regex string that can
5535 be used by the GNU regex library. Added into the file
5536 lib/silcutil/silcutil.[ch].
5538 Added silc_string_regex_combine to combine to regex strings
5539 into one so that they can be used as one regex string by
5540 the GNU regex library. Added into the file
5541 lib/silcutil/silcutil.[ch].
5543 Added silc_string_regex_match to match two strings. It returns
5544 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5546 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5548 * Imported GNU regex to the soruce tree into lib/contrib.
5549 Fixed some compiler warning from the regex.c.
5551 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Fixed MOTD command in the server to work in router environment.
5555 * Fixed the MOTD command in the client library to support
5556 the server argument in the command.
5558 * Added `nickname_len' argument to the silc_idlist_add_client
5559 in the server, as the `nickname' argument may be binary data
5562 * Added silc_idlist_get_channels to return all channels from
5565 * Implemented LIST command to the server. Affected file is
5568 * Implemented the LIST command to the client library and on the
5571 * Added [<user count>] argument to the LIST command reply.
5572 With private channels the user count is not shown.
5574 * Updated TODO and README.
5576 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5578 * The client entry's data.registered must be TRUE even with
5579 global client entry on global client list. The data.registered
5580 is used to check whether the client is anymore in the network,
5581 for example with WHOWAS command so it must be valid.
5583 * Fixed the WHOWAS command in the server. It now actually works
5584 in router environment. Added function into silcd/command_reply.c
5585 silc_server_command_reply_whowas_save.
5587 * Added silc_idlist_purge function to the silcd/idlist.c
5588 to periodically purge the ID Cache.
5590 * Fixed INFO command in the server. It works now in router
5591 environment. Added <server name> argument to the INFO command
5592 reply. Updated the protocol specs.
5594 * Fixed minor bug in silc_idcache_purge to not purge if the
5595 expire value is zero.
5597 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5598 they were buggy because of the WHOWAS information.
5600 * Fixed local command MSG to handle the async resolving of
5601 the remote client properly. It used to fail the first MSG.
5602 Affected file silc/local_command.c.
5604 * Added `data_len' field to SilcIDCache context.
5606 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5608 * Update TODO. Todo in commands in the server.
5610 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5612 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5613 used by routers as broadcast packet to inform other routers
5614 about the changed user mode.
5616 Implemented the notify handling in the server. Affected file is
5617 silcd/packet_receive.c. Added the function
5618 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5620 * Added new generic Channel Payload and deprecated the New Channel
5621 Payload. The New Channel Payload is now the generic Channel
5624 * Added new argument `mode' to the silc_server_send_new_channel
5625 as it is required in the Channel Payload now.
5627 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5628 and created a new and real SilChannelPayload to represent the
5629 new generic Channel Payload. Implemented the encode/decode
5630 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5632 * Added silc_server_get_client_channel_list to return the list
5633 of channels the client has joined for WHOIS command reply.
5634 Affected file silcd/server.[ch].
5636 * Implemented the channel list sending in the WHOIS command reply
5637 in server and in the client.
5639 Implemented the channel list displaying on the user interface
5640 as well. Affected file silc/client_ops.c.
5642 * Added silc_channel_payload_parse_list to parse list of Channel
5643 Payloads. It returns SilcDList list of SilcChannelPayloads.
5644 Client for example can use this function to parse the list of
5645 channels it receives in the WHOIS command reply. The caller
5646 must free the list by calling silc_channel_payload_list_free.
5647 Affected files lib/silccore/silcchannel.[ch].
5649 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5651 * Added one new argument <user mode> to the WHOIS command reply
5652 to return the mode of the user in SILC. Updated the protocol
5655 Implemented it to the server and client.
5657 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5659 * Fixed the mode printing on the user interface on joining.
5660 Affected file silc/client_ops.c.
5662 * Implemented the UMODE command and user modes in general to the
5663 client library and to the user interface.
5665 * Implemented the UMODE command to the server.
5667 * The server now sends UNKNOWN_COMMAND error status if client sends
5668 unknown command. Affected file silcd/command.c.
5670 * All server commands now handle the command identifier the right
5671 way when sending the command reply to the client. The client can
5672 use to identify the command replies with the identifier.
5674 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5676 * Added silc_server_get_client_route to resolve the route to
5677 the client indicated by the client ID. Affected file is
5680 * Added silc_server_relay_packet as general function to relay
5681 packet to arbitrary destination. This deprecates functions
5682 like _send_private_message_key, _relay_notify etc. Affected
5683 file is silcd/packet_send.[ch].
5685 Removed silc_server_send_key_agreement,
5686 silc_server_send_private_message_key and
5687 silc_server_packet_relay_notify functions from the file
5688 silcd/packet_send.[ch].
5692 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5693 server. Affected file silcd/packet_receive.[ch].
5695 * Implemented the KILL command to the client. Implemented the
5696 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5697 Affected files lib/silcclient/command[_reply].c and
5698 lib/silcclient/client_notify.c. Implemented the KILL notify
5699 printing in the user inteface.
5701 * Fixed a lot silc_parse_nick memory leaks from the client
5702 library in the file lib/silcclient/command.c.
5704 * Changed the silc_server_send_notify_on_channels's `sender'
5705 argument from SilcSocketConnection to SilcClientEntry to
5706 check the sender as entry and not as connection object and not
5707 to send to the client provided as argument. The affected file
5708 is silcd/packet_send.[ch].
5710 * The notify packets that are destined directly to the client used
5711 to not to be processed by the server. Now changed that and the
5712 server processes all notify packets. After relaying the packet
5713 to the client the notify packet is processed in the server.
5715 * The silc_server_free_client_data now checks whether there is
5716 pending outgoing traffic for the client and purges the data to
5717 the network before removing the client entry.
5719 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5721 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5722 an client is killed from the SILC Network. Updated the protocol
5725 Added new function silc_server_send_notify_killed to the
5726 silcd/packet_send.[ch].
5728 * Added function silc_server_packet_relay_notify to relay notify
5729 packets that are destined directly to a client. In this case
5730 the server does not process the notify packets but merely relays
5731 it to the client. Affected file silcd/packet_send.[ch].
5733 Added also silc_server_packet_process_relay_notify to check
5734 whereto relay the notify. Affected file is
5735 silcd/packet_receive.[ch].
5737 * Implemented the KILL command to the server.
5741 * Added the backup schema desgined last fall to the protocol
5742 specs for everyone to see. The specification is in the
5743 *-spec-xx.txt draft and the packet type definitions for the
5744 backup routers is in *-pp-xx.txt draft. Thusly, added also
5745 new packet type SILC_PACKET_CELL_ROUTERS.
5747 * A big security problem in the implementation discovered. The
5748 signoff of an client did not cause new channel key generation
5749 which it of course should've done. The channel keys must be
5750 always re-generated when client leaves (or signoffs) the channel.
5751 The silc_server_remove_from_channels funtion now handles
5752 the channel key re-generation.
5754 * Added `sender' argument to the silc_server_send_notify_on_channels
5755 to not to send the client provided as argument. Affected file
5756 silcd/packet_send.[ch].
5758 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5760 * Implemented OPER and SILCOPER commands into the server and
5763 * Added silc_auth_verify and silc_auth_verify_data to verify
5764 the authentication directly from the authentication payload.
5765 It supports verifying both passphrase and public key based
5766 authentication. Affected file lib/silccore/silcauth.[ch].
5768 * Added `hash' field to the SilcIDListData structure. It is the
5769 hash negotiated in the SKE protocol. Affected file is
5772 * Slight redesigning of the SilcAuthPayload handling routines.
5773 Do not send SilcPKCS but SilcPublicKey as argument.
5775 * Implemented the public key authentication support to the
5776 serverconfig. The public key is loaded from the provided path
5777 and saved as authentication data to void * pointer. Thus,
5778 changed the unsigned char *auth_data to void *auth_data;
5780 * Fixed SHUTDOWN command to send the reply before the server
5781 is shutdown. :) Affected file silcd/command.c.
5783 * Fixed fatal bug in CONNECT command. The hostname was invalid
5784 memory and server crashed. Affected file silcd/command.c.
5786 * Fixed fatal bug in CLOSE command. The server_entry became
5787 invalid but was referenced later in the command. Affected file
5790 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5792 * Fixed fatal bug in failure packet handling. Server ignored
5793 the failure and thus crashed when it came.
5797 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5799 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5800 that the command may be executed only once in (about) 2 seconds.
5801 The old SILC_CF_LAG flag is same but allows command bursts up
5802 to five before limiting.
5804 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5805 server code. Various commands now includes the CF_LAG_STRICT
5806 flag to disallow any kind of miss-use of the command.
5808 * Fixed the silc_buffer_unformat to not to allocate any data
5809 if the length of the data is zero. It used to allocate the
5810 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5812 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5814 * Changed the format of AdminConnection configuration section
5815 in the server. Added username of the admin to the format.
5816 Affected files silcd/serverconfig.[ch].
5818 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5819 to return admin configuration data by host, username and/or
5822 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5824 * Implemented WHOWAS command to the server. Added the functions:
5826 silc_server_command_whowas_parse,
5827 silc_server_command_whowas_send_reply,
5828 silc_server_command_whowas_from_client and
5829 silc_server_command_whowas_from_server
5831 * Added <Client ID> argument to the WHOWAS command reply. Updated
5832 the protocol specs accordingly.
5834 * Implemented WHOWAS command and command_reply to the client
5837 Implemented the WHOWAS printing on the user interface.
5839 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5841 * Added new argument to the WHOWAS command reply, the real name.
5842 It is an optional argument. Updated the protocol specs.
5844 * Added SilcIDCacheDestructor callback that is registered when
5845 the SilcIDCache is allocated. The callback is called when
5846 an cache entry in the ID Cache expires, or is purged from the
5847 cache. Added into lib/silccore/idcache.[ch].
5849 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5850 to destruct the client entries when the cache entry expires.
5851 Other ID Cache's in server and in the client library ignores
5854 * If the ID Cache entry's `expire' field is zero then the entry
5855 never expires. Added boolean `expire' argument to the
5856 silc_idcache_add function in the lib/silccore/idcache.[ch].
5857 If it is TRUE the default expiry value is used.
5859 * Added silc_server_free_client_data_timeout that is registered
5860 when client disconnects. By default for 5 minutes we preserve
5861 the client entry for history - for WHOWAS command.
5863 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5865 * Added support to the server to enforce that commands are not
5866 executed more than once in 2 seconds. If server receives
5867 commands from client more frequently, timeout is registered
5868 to process the commands. Affected file silcd/command.c.
5869 Added new function silc_server_command_process_timeout.
5871 * Changed NICK_NOTIFY handling in client library to check that
5872 if the client's nickname was changed, so there is no need to
5873 resolve anything from the server.
5875 * Removed error printing from the WHOIS and IDENTIFY commands.
5876 If error occurs then it is ignored silently in the client library.
5877 The application, however, may map the received error to
5878 human readable error string. The application currently maps
5879 the NO_SUCH_NICKNAME error to string.
5881 * Made the command status message public to the application. Moved
5882 them from lib/silcclient/command_reply.c to
5883 lib/silcclient/command_reply.h. The application can map the
5884 received command status to the string with the
5885 silc_client_command_status_message function.
5887 * Added check to the server to check that client's ID is same
5888 as the Source ID in the packet the client sent. They must
5891 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5893 * Added dist-bzip hook to the Makefile.am to make bzip2
5894 compressed distributions.
5896 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5898 * Server now enforces the maximum length for the nickname and
5899 the channel as protocol specification dictates. 128 bytes for
5900 nickname and 256 bytes for channel name.
5902 * Moved the WHOIS printing to the application. The client libary
5903 does not print out the WHOIS information anymore, the application
5904 must do it. Renamed silc_client_command_reply_whois_print to
5905 the silc_client_command_reply_whois_save.
5907 The client's idle time is also sent to the application now, and
5908 the idle is shown on screen.
5910 * Added silc_client_command_reply_identify_save to save the
5911 received IDENTIFY entries.
5913 * Do not check for channel private keys in message sending and
5914 reception if the channel does not have the PRIVKEY mode set.
5915 Affected file lib/silclient/client_channel.c.
5917 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5919 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5920 just surfaced after chaning the JOIN procedure.
5922 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5924 * Added silc_client_get_clients_by_list to get client entries
5925 from Client ID list, that is returned for example by JOIN
5926 and USERS command replies. The application should use this
5927 function for example when JOIN command reply is received to
5928 resolve the clients already on the channel (library does not
5929 do that anymore as USERS command reply is not used in the JOIN
5930 procedure anymore). Affected files lib/silcclient/silcapi.h and
5931 lib/silcclient/idlist.c.
5933 * JOIN command reply and USERS command reply returns now SilcBuffer
5934 pointers instead of unsigned char pointers when returning
5935 the client list and mode list.
5937 * Added <Client ID> argument to the JOIN command reply, mainly
5938 for the server to identify for which client the command was
5939 originally sent. Updated protocol specs accordingly.
5941 * Added SilcDlist private_key pointer to the SilcChannelEntry
5942 in the client to support the channel private keys. Affected
5943 file is lib/silcclient/idlist.h.
5945 * Added SilcChannelPrivateKey argument to the function
5946 silc_client_send_channel_message so that application can choose
5947 to use specific private ke if it wants to. If it is not provided,
5948 the normal channel key is used, unless private keys are set.
5949 In this case the first (key that was added first) is used
5950 as the encryption key.
5952 * Implemented the support for channel private key handling.
5953 Implemented the following functions:
5955 silc_client_add_channel_private_key,
5956 silc_client_del_channel_private_keys,
5957 silc_client_del_channel_private_key,
5958 silc_client_list_channel_private_keys and
5959 silc_client_free_channel_private_keys
5961 Affected file lib/silcclient/client_channel.c.
5963 * Added the support for the private keys in the channel message
5964 sending and encryption and in the message reception and
5965 decryption. Affected funtions are
5966 silc_client_send_channel_message and silc_client_channel_message.
5968 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5970 * Added SKE's key verify callback to the client library's
5971 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5973 * Removed the statement that server (or router) must send USERS
5974 command reply when joining to the channel so that the client
5975 knows who are on the channel. Instead, the client list and
5976 client's mode list is now sent in the JOIN command reply to the
5977 client who joined channel. This is better solution.
5979 * Added function silc_server_get_users_on_channel and function
5980 silc_server_save_users_on_channel to the silcd/server.[ch].
5982 * Removed function silc_server_command_send_users from the
5985 * Do not show topic on the client library anymore. The topic is
5986 sent in the command reply notify to the application and the
5987 application must show the topic now.
5989 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5991 * Added client searching by nickname hash into the IDENTIFY and
5992 WHOIS commands in the server as they were clearly missing from
5993 them. Affected file is silcd/command.c.
5995 * Fixed a bug in private message receiving in the client library.
5996 The remote ID was freed and it wasn't supposed, now it is
5999 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6001 * Minor fix to the channel payload; allocate the data area, as it
6002 needs to be of specific length.
6004 * If the key agreement port is zero then the operating
6005 system will define the bound port. Affected files are
6006 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
6008 * Added new function silc_channel_payload_decrypt into the file
6009 lib/silccore/silcchannel.[ch].
6011 * Moved the channel message etc, check from silc_packet_decrypt
6012 to applications. The library calls now a generic
6013 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
6014 when the packet is either normal or special. This was done to
6015 allow more wide range of checking that was not allowed when
6016 the code was in library. Now applications can do virtually any
6017 checks to the packet and return to the library the decision how
6018 the packet should be processed. Affected files are
6019 lib/silccore/silcpacket.[ch].
6021 Added silc_server_packet_decrypt_check to the server and
6022 silc_client_packet_decrypt_check to the client library.
6024 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
6025 to send with specified source and destination information.
6027 * Channel message delivery between routers was broken after the
6028 channel key distribution was fixed earlier. The channel key
6029 was used be to distributed to other routers as well which is not
6030 allowed by the protocol. Now this is fixed and channel keys
6031 really are cell specific and the channel message delivery between
6032 routers comply with the protocol specification.
6034 * Fixed various commands in server to check also the global list
6035 for the channel entry and not just the local list. The affected
6036 file silcd/command.c.
6038 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6040 * Added assert()s to buffer formatting and unformatting routines
6041 to assert (if --enable-debug) when error occurs. Affected
6042 file: lib/silcutil/silcbuffmt.c.
6044 * Changed to auto-reconnect to check whether the remote host is
6045 router and register the re-connect timeout if it is. It used
6046 to check that whether we are normal server, but router must do
6047 auto-reconnect with another router as well. Affected file
6050 * Removed the [<key len>] option from CMODE command as the cipher
6051 name decides the key length, nowadays. See the defined ciphers
6052 from the protocol specification.
6054 * Added [<hmac>] option to the CMODE command to define the HMAC
6055 for the channel. Added SILC_CMODE_HMAC channel mode.
6057 * Added [<hmac>] option for the JOIN command so that user can
6058 select which HMAC is used to compute the MACs of the channel
6061 * Added Hmac field to the Channel Message Payload. The integrity
6062 of plaintext channel messages are now protected by computing
6063 MAC of the message and attaching the MAC to the payload. The
6064 MAC is encrypted. Now, it is clear that this causes some
6065 overhead to the size of the packet but rationale for this is that
6066 now the receiver can verify whether the channel message decrypted
6067 correctly and also when private keys are set for the channel the
6068 receiver can decrypt the packet with several keys and check from
6069 the MAC which key decrypted the message correctly.
6071 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
6072 lib/silccrypt/silccipher.[ch].
6074 * Added silc_hash_len to return the digest length into the
6075 lib/silcrypt/silchash.[ch].
6077 * Rewrote parts of Silc Channel Payload interface in the
6078 lib/silccore/silcchannel.[ch]. The encode function now also
6079 encrypts the packet and parse function decrypts it.
6081 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6083 * Fixed a minor formatting bug in the SKE's key material processing.
6084 It actually might have processed the keys wrong way resulting
6087 * Redefined the mandatory HMAC algorithms and added new algorithms.
6088 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
6089 and hmac-md5 truncated to 96 bits. The mandatory is now
6090 hmac-sha1-96. Rest are optional (including the one that used
6091 to be mandatory). Rationale for this is that the truncated HMAC
6092 length is sufficient from security point of view and can actually
6093 make the attack against the HMAC harder. Also, the truncated
6094 HMAC causes less overhead to the packets. See the RFC2104 for
6097 * Added new [hmac] configuration section. The SKE used to use
6098 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
6099 is of course wrong. The official names that must be proposed in
6100 the SKE are the ones defined in the protocol specification
6101 (hmac-sha1-96 for example). The user can configure any hmac
6102 using any hash function configured in the [hash] section. At
6103 least, the mandatory must be configured.
6105 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
6107 * Added HMAC list to the SKE proposal list. It has now both
6108 hash algorithm list and HMAC list. This makes the protocol
6109 incompatible with previous versions. The SKE now seems to work
6110 the way it is supposed to work, for the first time actually.
6112 * Defined plain Hash algorithms to the protocol specification.
6115 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6117 * Implemented support for key agreement packets into the server.
6118 Added functions silc_server_key_agreement and
6119 silc_server_send_key_agreement. Other than these functions,
6120 server has nothing to do with this packet.
6122 * Added support for private message key packets into the server.
6123 Added functions silc_server_private_message_key and
6124 silc_server_send_private_message_key.
6128 * Changed the silc_[client|server]_protocol_ke_set_keys to be
6129 called in the protocol's final callback instead in the END
6130 protocol state. This makes a little more sense and in the same
6131 time in client we can use the same protocol routines for normal
6132 key exchange and to key agreement packet handling as well.
6134 * Added to both client's and server's KE protocol context the
6135 SilcSKEKeyMaterial pointer to save the key material. We will
6136 bring the key material to the protocol's final callback by doing
6137 this. The final callback must free the key material.
6139 * Added SKE's packet_send callback into client's KE protocol
6140 context so that the caller can choose what packet sending function
6141 is used. This way we can use different packet sending when
6142 doing normal SKE when doing key agreement packet handling (in
6143 the key agreement packet handling we do not want to encrypt
6146 * Implemented the responder side of the key agreement routines
6147 in the client. The client can now bind to specified port and
6148 accept incoming key negotiation. The key material is passed
6149 to the application after the protocol is over.
6151 * Implemented the processing of incoming Key Agreement packet
6152 in the client. Added function silc_client_key_agreement to
6155 * Implemented the intiator side of the key agreement routines
6156 in the client. The client can now initiate key agreement with
6157 another remote client. The key material is passed to the
6158 application after the protocol is over.
6160 * Created client_keyagr.c to include all the key agreement
6163 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
6164 SILC_TASK_CALLBACK except that it is not static.
6166 * Created client_notify.c and moved the Notify packet handling
6167 from the client.[ch] into that file.
6169 * Created client_prvmsg.c and moved all private message and
6170 private message key routines from the client.[ch] into that file.
6172 * Create client_channel.c and moved all channel message and
6173 channel private key routines from the client.[ch] into that file.
6175 * Changed silc_client_get_client_by_id_resolve to resolve with
6176 WHOIS command instead of IDENTIFY command, in the file
6177 lib/silclient/idlist.c.
6179 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6181 * Implemented the SKE's responder side to the Client library.
6183 * When FAILURE is received to the protocol do not trust it
6184 blindly. Register a timeout to wait whether the remote closes
6185 the connection as it should do it, only after that process the
6186 actual failure. This was changed to both client and server.
6188 * Added client_internal.h to include some of the structures
6189 there instead of client.h in lib/silcclient/.
6191 * Added function silc_task_unregister_by_callback to unregister
6192 timeouts by the callback function.
6194 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6196 * Some "Incomplete WHOIS info" errors has been appearing on the
6197 log files. Took away the entry->userinfo check from WHOIS
6198 reply sending. The entry->userinfo is now " " if client did not
6199 provide one. I thought this was fixed earlier but something
6200 is wrong still. Let's see if the error still appears.
6202 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6204 * Fixed a minor bug in the login when the channel key is
6205 re-generated in the server. It used to generate the key in
6206 wrong order and thus caused problems in the channel traffic.
6208 * Fixed a minor bug in channel key distsribution after
6209 KICK command. The key was not sent to the router even though
6212 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6214 * Added silc_ske_process_key_material_data as generic routine
6215 to process any key material as the SILC protocol dictates. The
6216 function is used by the actual SKE library but can be used by
6217 applications as well. This relates to the private message keys
6218 and the channel private keys since they must be processed the
6219 same way the normal SILC session keys. The protocol dictates
6220 this. Affected files: lib/silcske/silcske.[ch].
6222 Added also silc_ske_free_key_material to free the
6223 SilcSKEKeyMaterial structure.
6225 * Defined silc_cipher_set_key function to set the key for
6226 cipher without using the object's method function. The affected
6227 files: lib/silccrypt/silccipher.[ch].
6229 * Implemented silc silc_client_add_private_message_key,
6230 silc_client_add_private_message_key_ske,
6231 silc_client_del_private_message_key,
6232 silc_client_list_private_message_keys and
6233 silc_client_free_private_message_keys functions in the
6236 Added functions silc_client_send_private_message_key to send
6237 the Private Message Key payload and silc_client_private_message_key
6238 to handle incoming Private Message Key payload.
6240 * Added Cipher field to the Private Message Key payload to set
6241 the cipher to be used. If ignored, the default cipher defined
6242 in the SILC protocol (aes-256-cbc) is used.
6244 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6246 * Removed lib/silcclient/ops.h file.
6248 Redefined parts of the SILC Client Library API. Created new
6249 file silcapi.h that deprecates the ops.h file and defines the
6250 published Client Library API. Defined also private message key
6251 API and channel private key API into the file.
6253 This is the file that the application must include from the
6254 SILC Client Library. Other files need not be included by
6255 the application anymore.
6257 * Added new key_agreement client operation callback and also
6258 defined the Key Agreement library API for the application.
6260 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6262 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
6263 is used by clients to request key negotiation between another
6264 client in the SILC network. If the negotiation is started it
6265 is performed using the SKE protocol. The result of the
6266 negotiation, the secret key material, can be used for example
6267 as private message key.
6269 Implemented the Key Agreement payload into the files
6270 lib/silccore/silauth.[ch].
6272 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6274 * Redefined ciphers for the SILC protocol. Added some new ciphers
6275 and defined the key lengths for the algorithms. Changed the
6276 code accordingly. The default key length is now 256 bits.
6278 * Fixed SKE key distribution function silc_ske_process_key_material
6279 when the key length is more than 128 bits. The default key
6280 length in SILC is now 256 bits.
6282 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
6283 to indicate unsupported algorithm.
6285 * Renamed rijndael.c to aes.c and all functions as well.
6287 * Fixed a long standing channel key setting bug in client library.
6288 Weird that it has never surfaced before.
6290 * Fixed bug in channel deletion. If the entire channel is removed
6291 then it must also delete the references of the channel entry
6292 from the client's channel list as the client's channel entry and
6293 the channel's client entry share same memory.
6295 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6297 * Implemented CONNECT and SHUTDOWN commands in the client.
6299 * Implemented CLOSE command to the client.
6301 * Added the function silc_idlist_find_server_by_name into the
6302 files silcd/idlist.[ch].
6304 Added the function silc_idlist_find_server_by_conn into the
6305 files silcd/idlist.[ch].
6307 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6309 * DIE command was renamed to SHUTDOWN. Updated the both code
6312 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
6313 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
6315 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
6318 * Added function silc_server_create_connection function to create
6319 connection to remote router. My server implementation actually
6320 does not allow router to connect to normal server (it expects
6321 that normal server always initiates the connection to the router)
6322 so the CONNECT command is only good for connecting to another
6325 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
6328 or some other client was kicked from the channel.
6330 Implemented the handling of the notify type to both client
6333 Implemented silc_server_send_notify_kicked to send the KICKED
6334 notify. It is used to send it to the server's primary router.
6336 * Implemented the KICK command into server and client.
6338 * Added `query' argument to the silc_idlist_get_client function
6339 to indicate whether to query the client from server or not if
6342 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
6343 to indicate that the client is not channel founder.
6347 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6349 * Removed the rng context from SilcPacketContext structure and
6350 changed that the packet routine uses the Global RNG API.
6352 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6354 * Added support for quit message that client can "leave" on the
6355 channel when it quits the SILC. It is ditributed inside the
6356 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6358 Added silc_server_free_client_data that will take the
6359 signoff message as argument.
6361 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6363 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6365 * Updated parts of the protocol specification to keep it up
6368 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6370 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6371 payloads in one packet.
6373 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6374 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6375 use now the new List flag.
6377 * Also deprecated the following packet types: REPLACE_ID,
6378 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6380 * Added list support for Notify packet in server.
6382 * Added silc_server_send_notify_channel_change to send the
6383 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6384 the silc_server_send_replace_id.
6386 * Added silc_server_send_notify_nick_change to send the
6387 NICK_CHANGE notify type. Deprecates the function
6388 silc_server_send_replace_id.
6390 * Added silc_server_send_notify_join to send the JOIN notify type.
6391 Deprecates the function silc_server_send_new_channel_user.
6393 * Added silc_server_send_notify_leave to send LEAVE notify type.
6394 Deprecates the function silc_server_send_remove_channel_user.
6396 * Added silc_server_send_notify_cmode and
6397 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6398 types. Deprecates the silc_server_send_set_mode function.
6400 * Added SERVER_SIGNOFF notify type to indicate that server has
6401 quit. This means that all clients on the channel from that
6402 server will drop. This can be also used when netsplit happens.
6404 Deprecated REMOVE_ID packet type since it is not needed anymore
6407 Added silc_server_send_notify_server_signoff to send the
6408 SERVER_SIGNOFF notify type. Deprecates the function
6409 silc_server_send_remove_id.
6411 Added also silc_server_send_notify_signoff to send the
6412 SIGNOFF notify type.
6414 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6415 SILC protocol from this day on. Changed the protocol
6416 specification as well.
6418 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6419 notify type. It is used between routers to notify about
6420 topic changes on a channel.
6422 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6425 * Partly updated the protocol specification to comply with the
6426 changes now made. It is still though a bit outdated.
6428 * The JOIN notify type now takes one extra argument <Channel ID>.
6429 The packet used to be destined to the channel but now the
6430 JOIN type may be sent as list thus it is impossible to
6431 destine it to any specific channel. By adding this argument
6432 it is again possible.
6434 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6436 * Added CREDITS file. The CHANGES and CREDITS file will appear
6437 in the distribution as well.
6439 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6441 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6442 types in the server's silcd/packet_receive.c.
6444 * Implemented CMODE and CUMODE to work in router environment.
6446 * Fixed minor encoding and decoding buglet from the
6447 lib/silccore/silcmode.c.
6449 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6452 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6454 * Changed all SilcConfigServer* and silc_config_server* to
6455 SilcServerConfig* and silc_server_config*, respectively.
6458 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6460 * Associated the ID (client or server ID) to the Authentication
6461 Payload to avoid any possibility of forging. Updated the
6462 protocol specification and the code accordingly.
6464 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6466 * The RSA key length is now save to the RsaKey context in the
6467 key generation process in lib/silccrypt/rsa.c. The key length
6468 is now used to figure out the maximum size of the block allowed
6469 to be encrypted/signed.
6471 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6472 is equivalent to the silc_mp_mp2bin but does not allocate any
6475 * Changed silc_mp_mp2bin API to take length argument. If it is
6476 non-zero then the buffer is allocated that large. If zero, then
6477 the size is approximated using silc_mp_sizeinbase, which however
6480 * Created Global RNG API which is global RNG that application can
6481 initialize. After initializing, any routine anywhere in the
6482 code (including library) can use RNG without allocating a new
6483 RNG object. This was done to allow this sort of use of the
6484 RNG in code that has no chance to allocate RNG object. All
6485 applications currently allocate this and many routines in the
6486 library use this. Affected file lib/silccrypt/silcrng.[ch].
6488 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6489 it to use the Global RNG API.
6491 * Defined Authentication Payload into protocol specification that
6492 is used during SILC session to authenticate entities. It is
6493 used for example by client to authenticate itself to the server
6494 to obtain server operator privileges.
6496 Implemented this payload into the lib/silccore/silcauth.[ch].
6497 Implemented also routines for public key based authentication
6498 as the new protocol specification dictates.
6500 Moved definitions of different authentication methods from
6501 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6503 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6504 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6505 silc_pkcs_verify_with_hash functions into the file
6506 lib/silccrypt/silcpkcs.[ch].
6508 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6510 * The client entry's userinfo pointer must be always valid.
6511 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6512 will fail since it requires the userinfo. Now, the userinfo
6513 is allocated as "" if actual userinfo does not exist. Actually,
6514 it must exist and it is totally Ok to drop client connections
6515 that does not announce the userinfo. However, we will make
6516 this workaround for now.
6518 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6519 to return the remote port by socket.
6521 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6523 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6524 SILC_SERVER_PENDING_EXEC and added an new macro
6525 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6526 data or when error occurs while processing the pending command.
6528 Added new argument `destructor' into silc_server_command_pending
6529 and to the SilcServerCommandPending object. This destructor is
6530 now called after calling the pending callback or if error occurs
6531 immediately. If error occurs the actual pending callback won't
6532 be called at all - only the destructor. The destructor may be
6533 NULL if destructor is not needed.
6535 All this applies for client library code as well. Similar
6536 changes were made there as well for the pending commands.
6538 In the client, the application must now allocate the
6539 SilcClientCommandContext with the silc_client_command_alloc
6542 * Added reference counter to the SilcServerCommandContext. Added
6543 function silc_server_command_alloc and silc_server_command_dup
6546 Same type of functions added to the client library for the same
6549 * Removed the cmd_ident from IDListData away since it is now
6550 global for all connections. It is the command identifier used
6551 in command sending and with pending commands. The affected file
6554 * Added reference counter to the SilcSocketConnection objecet to
6555 indicate the usage count of the object. The object won't be
6556 freed untill the reference counter hits zero. Currently only
6557 server uses this, and client ignores it. The client must be
6558 set to use this too later. The affected files are
6559 lib/silccore/silcsockconn.[ch]. Added also the function
6560 silc_socket_dup to increase the reference counter.
6562 This was mainly added because it is possible that the socket
6563 is removed underneath of pending command or other async
6564 operation. Now it won't be free'd and proper DISCONNECTING
6565 flags, etc. can be set to avoid sending data to connection that
6566 is not valid anymore.
6568 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6569 the connection. After that it sets SILC_SET_DISCONNECTED.
6570 It is, however, possible that the socket data is not still freed.
6571 The silc_server_packet_process now checks that data is not
6572 read or written to connection that is DISCONNECTED. The socket
6573 get's freed when the reference counter hits zero.
6575 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6577 * Changed the client operation API: channel_message operation's
6578 `sender' is now the client entry of the sender, not the nickname
6579 and the `channel' is the channel entry, not the channel name.
6581 In the private_message operation the `sender' is now also the
6582 client entry of the sender not the nickname.
6584 Affected file is lib/silcclient/ops.h and all applications
6585 using the client operations.
6587 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6589 * Moved the calling of ops->connect() from connect_to_server_final
6590 into receive_new_id functin since that is the point when the
6591 client is actually allowed to send traffic to network. The
6592 affected file is lib/silcclient/client.c.
6594 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6596 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6597 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6598 (if needs broadcasting) instead of broadcasting the packets one
6599 by one which would make a burst in the network traffic.
6601 * Added `broadcast' argument to the functions in silcd/server.[ch]
6602 silc_server_create_new_channel[_with_id] to indicate whether
6603 to send New Channel packet to primary router.
6605 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6607 * Added new function into the silcd/server.[ch] files:
6608 silc_server_create_new_channel_with_id to create new channel with
6609 already existing Channel ID.
6611 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6612 lib/silccore/silcpacket.h. This packet is used t send list of
6613 Set Mode payloads inside one packet. Server uses this to set
6614 the modes for the channels and clients on those channels, that it
6615 announced to the router when it connected to it. The protocol
6616 specification has been updated accordingly.
6618 * The silc_server_new_channel did not handle the packet coming
6619 from normal server as it normally does not send that. However,
6620 when it announces its channels it does send it. Implemented
6621 the support for that.
6623 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6624 into the file lib/silccore/id.h.
6626 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Fixed memory leaks in the functions silc_idlist_del_client,
6629 silc_idlist_del_channel and silc_idlist_del_server in the file
6630 silcd/idlist.c. All of those leaked like a sieve.
6632 * Fixed some small memory leaks in the client's function
6633 silc_client_notify_by_server.
6635 * Added functions into silcd/server.c: silc_server_announce_clients,
6636 silc_server_announce_channels and silc_server_announce_server.
6637 These functions are used by normal and router server to announce
6638 to its primary router about clients, channels and servers (when
6639 router) that we own. This is done after we've connected to the
6642 These functions effectively implements the following packet types:
6643 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6644 and SILC_PACKET_NEW_ID_LIST.
6646 * Added new functions into the silcd/packet_receive.[ch]:
6647 silc_server_new_id_list, silc_server_new_channel_list and
6648 silc_server_new_channel_user_list to handle the incoming
6649 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6651 * Added support of changing Channel ID in the function
6652 silc_server_replace_id. If the server that announces a channel
6653 to the router already exists in the router (with same name but
6654 with different Channel ID), router is responsible to send
6655 Replace ID packet to the server and force the server to change
6656 the Channel ID to the one router has.
6658 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6659 client that the Channel ID has been changed by the router. The
6660 normal server sends this to the client. Client must start using
6661 the new Channel ID as the channel's ID.
6663 Implemented handling of this new type into lib/silcclient/client.c
6664 into the function silc_client_notify_by_server.
6666 * Added new function silc_idlist_replace_channel_id into the files
6667 silcd/idlist.[ch] to replace the Channel ID.
6669 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6671 * Call silc_server_command_identify_check always when processing
6672 the IDENTIFY command in silcd/command.c
6674 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6676 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6677 send keepalive packets. The packet can be sent by clients,
6678 servers and routers.
6680 Added function silc_socket_set_heartbeat into the file
6681 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6682 If not set, the heartbeat is not performed. The actual
6683 heartbeat is implemented in the low level socket connection
6684 library. However, application is responsible of actually
6687 Added silc_server_send_heartbeat to send the actual heartbeat
6688 packet into silcd/packet_send.[ch]. Server now performs
6689 keepalive with all connections.
6691 * Added silc_task_get_first function into lib/silcutil/silctask.c
6692 to return the timeout task with shortest timeout. There was a bug
6693 in task unregistration that caused problems. TODO has been
6694 updated to include that task system must be rewritten.
6696 * The client library will now resolve the client information when
6697 receiving JOIN notify from server for client that we know but
6698 have incomplete information.
6700 * Rewrote parts of silc_server_remove_from_channels and
6701 silc_server_remove_from_one_channel as they did not remove the
6702 channel in some circumstances even though they should've.
6704 * Encryption problem encountered in server:
6706 The LEAVE command used to send the Channel Key packet to the
6707 router immediately after generating it. However, the code
6708 had earlier sent Remove Channel user packet but not immediately,
6709 ie. it was put to queue. The order of packets in the router
6710 was that Channel Key packet was first and Remove Channel User
6711 packet was second, even though they were encrypted in the
6712 reverse order. For this reason, MAC check failed. Now, this
6713 is fixed by not sending the Channel Key packet immediately but
6714 putting it to queue. However, this is more fundamental problem:
6715 packets that are in queue should actually not be encrypted
6716 because packets that are sent immediately gets encrypted
6717 actually with wrong IV (and thus MAC check fails). So, packets
6718 that are in queue should be encrypted when they are sent to
6719 the wire and not when they put to the queue.
6721 However, the problem is that the current system has not been
6722 designed to work that way. Instead, the packet is encrypted
6723 as soon as possible and left to the queue. The queue is then
6724 just purged into wire. There won't be any fixes for this
6725 any time soon. So, the current semantic for packet sending
6728 o If you send packet to remote host and do not force the send
6729 (the packet will be in queue) then all subsequent packets to the
6730 same remote host must also be put to the queue. Only after the
6731 queue has been purged is it safe again to force the packet
6734 o If you send all packets immediately then it safe to send
6735 any of subsequent packets through the queue, however, after
6736 the first packet is put to queue then any subsequent packets
6737 must also be put to the queue.
6739 Follow these rules and everything works fine.
6741 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6743 * Added new function silc_server_remove_clients_by_server to
6744 remove all client entries from ID list when the server connection
6745 is lost. In this case it is also important to invalidate all
6746 client entires as they hold the invalid server entry. This
6747 fixes fatal bug when server has lost connection and will reconnect
6750 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6752 * Made some sanity checks to silc_server_daemonise like to check
6753 whether the requested user and group actually exists.
6755 * Added sanity check to SKE's silc_ske_responder_finish to check
6756 that the public and private key actually is valid.
6758 * Invalidate the client's nickname when receiving Replace ID
6759 packet and the Client ID is being replaced. This means that the
6760 server will query the nickname if someone needs it (client)
6763 * Sort the ID Cache in client library when the ID Cache data
6764 has changed (needs sorting).
6766 * Do not allow for SILC client to create several connections to
6767 several servers. The client does not support windows right now
6768 and generating multiple connections causes weird behaviour.
6770 Irssi-silc client does support windows and can handle several
6771 connections without problems, see: www.irssi.org and SILC plugin.
6773 * Fixed some places where client was added to the IDList. The
6774 rule of thumb is following (in order to get everything right):
6775 If the client is directly connected local client then the
6776 `connection' argument must be set and `router' argument must be
6777 NULL to silc_idlist_add_client function. If the client is not
6778 directly connected client then the `router' argument must
6779 bet set and the `connection' argument must be NULL to the
6780 silc_idlist_add_client function.
6782 * The funtion silc_server_packet_send_local_channel actually did
6783 not check whether the client was locally connected or not. It
6784 does that now. Fixed a bug related to LEAVE command.
6786 * Fixed Remove Channel User payload parsing bug in server's
6787 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6789 * The server's silc_server_save_channel_key now checks also the
6790 global ID list for the channel as it might not be in the local
6791 list. Fixed a bug related to LEAVE command.
6793 * Is this the end of the [<unknown>] buglet that has been lurking
6794 around for a long time? A little for loop fix in server's
6795 silc_server_command_whois_parse that is used by both IDENTIFY
6796 and WHOIS command. At least, this was a clear bug and a cause
6797 of one type of [<unknown>] buglet.
6799 * WHOIS and IDENTIFY commands call the function
6800 silc_server_command_[whois/identify]_check function even if
6801 we are not router server.
6803 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6805 * Added --with-gmp configuration option. If set the GMP
6806 is always compiled in the SILC source tree. If not set then
6807 it is checked whether the system has the GMP3 installed. If
6808 it has then the GMP won't be compiled (the system's headers
6809 and library is used), if it doesn't have it then the GMP is
6810 compiled in the SILC source tree.
6812 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6814 * Changed RSA private exponent generation to what PKCS #1
6815 suggests. We try to find the smallest possible d by doing
6816 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6817 not security fix but optimization.
6819 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6821 * Added new config entry [Identity] to fork the server and run
6822 it as specific user and group. A patch from Bostik.
6824 * Imported Dotconf configuration library into lib/dotconf.
6825 This will be used to create the SILC configuration files later.
6826 It will appear in the distsribution after this commit.
6828 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6830 * A big code auditing weekend happening. Auditing code for
6831 obvious mistakes, bugs and errors. Also, removing any code
6834 Removed files for being obsolete:
6836 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6837 inline in the file lib/silcutil/silcbuffer.h)
6839 o lib/silcutil/silcbufutil.c (the header has inline versions)
6841 Changed code to fix possible error conditions:
6843 o The buffer formatting routines now check that the destination
6844 buffer really has enough space to add the data. This applies for
6845 both buffer formatting and unformatting
6846 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6847 unformatting was changed to accomodate following rules:
6848 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6849 sent to the function while XXX_*STRING will not allocate or copy
6850 the data into the buffer. Instead it sets the pointer from the
6851 buffer into the pointer sent as argument (XXX_*STRING used to
6852 require that the pointer must be allocated already). This change
6853 makes this whole thing a bit more consistent and more optimized
6854 (note that the data returned in the unformatting with XXX_*STRING
6855 must not be freed now). The routines return now -1 on error.
6857 o Tried to find all code that use buffer_format and buffer_unformat
6858 and added return value checking to prevent formatting and
6859 especially unformatting errors and possible subsequent fatal
6862 o Changed ske->x and ske->KEY to mallocated pointers in
6863 lib/silcske/silcske.h. Fixed possible data and memory leak.
6865 o Added return value checking to all *_parse* functions. Fixed
6866 many memory leaks as well.
6868 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6869 so that buffer overflows would not happen. All code now also
6870 checks the return value as it can fail.
6872 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6874 * Added reconnection support to server if the normal server looses
6875 its connection to the router (for example if router is rebooted).
6876 The server performs normal reconnection strategy implemented
6877 to the server. Affected file silcd/server.c.
6879 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6881 * Added new packet type SILC_PACKET_SET_MODE that is used to
6882 distribute the information about changed modes (for clients,
6883 channels and clients channel modes) to all routers in the
6884 network. Updated the protocol specification accordingly.
6886 Added functions into silcd/packet_send.c and
6887 silcd/packet_receive.c: silc_server_send_set_mode,
6888 silc_server_set_mode.
6890 Added new files silcmode.[ch] into lib/silccore that implements
6891 the encoding and decoding of Set Mode Payload. Added new type
6892 SilcSetModePayload. Moved the definitions of different modes
6893 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6895 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6897 * Oops, a little mistake in server's connection authentication
6898 protocol. The protocol is not ended with FAILURE but with
6899 SUCCESS if the authentication is Ok. :) Affected file is
6902 * Implemented NICK_CHANGE notify handling in server in the file
6903 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6904 the local clients on the channel. After the changing nickname
6905 in router environment snhould work and the [<unknown>] nickname
6906 should appear no more.
6908 The silc_server_replace_id function that receives the Replace ID
6909 payload now sends the NICK_CHANGE notify type also in the file
6910 silcd/packet_receive.c
6912 * Changed WHOIS and IDENTIFY command to support the maximum amount
6913 of arguments defined in protocol specs (3328 arguments). This
6914 fixed a bug that caused problems when there were more than three
6917 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6919 * Added extra parameter, command identifier, to the
6920 silc_client_send_command so that explicit command identifier
6923 Changed that ID list routines uses specific command identifier
6924 when sending WHOIS/IDENTIFY requests to the server so that they
6925 can be identified when the reply comes back.
6927 Affected files lib/silcclient/command.[ch],
6928 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6930 * Added `sender' argument to silc_server_packet_send_to_channel
6931 to indicaet the sender who originally sent the packet to us
6932 that we are now re-sending. Ignored if NULL. Affected file
6933 silcd/packet_send.[ch].
6935 * Added some server statistics support in silcd/server_internal.h
6936 SilcServerStatistics structure and around the server code. Also
6937 send some nice statistics information when client is connecting
6940 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6942 * Fixed channel ID decoding in server's JOIN command reply in
6943 silcd/command_reply.c
6945 * Fixed braodcasting of replace ID payload to not to send it if
6946 we are standalone server in silcd/packet_receive.c.
6948 * Fixed all channel message sending routines to not to send
6949 packets to clients that has router set, since they are routed
6950 separately in the same function earlier. Affects file
6951 silcd/packet_send.c and all channel packet sending functions.
6953 * In USERS reply, res_argv[i] are not allocated, the table
6954 is allocated. Thus changed that free the table, not its
6957 * In server's whois_check and identify_check if the client is
6958 locally connected do not send any WHOIS commands - they are not
6961 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6963 * Fixed some minor bugs in client when sending WHOIS command. The
6964 arguments was in wrong order.
6966 * Removed statis function add_to_channel from server in
6967 silcd/command.c that was previously used with the joining but
6970 * Tested USERS command in router environment successfully with two
6971 routers, two servers and two clients.
6973 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6975 * Reorganized the USERS command and command reply in client library
6976 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6977 When the command is given by user we register a pending command
6978 callback that will reprocess the command after the reply has been
6979 received from the server. When reprocessing the packet we then
6980 display the information. Thus, the USERS information is displayed
6981 now in the command callback instead of in the command reply
6982 callback. The processing of the command is same as previously
6983 when server has sent the command reply in the JOINing process.
6985 * Added to USERS command in silcd/command_reply.c to join the client,
6986 we didn't use to know about, to the channel after we've created
6987 a client entry for it. Also, for clienet we did know already still
6988 check whether it is on the channel or not and add it if not.
6990 * Removed silc_server_command_join_notify as the function and its
6993 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6995 * Changed the client's pending command handling to the same as the
6996 server's pending command handling. It is also now possible to
6997 execute command reply functions from other command reply
6998 function as the function callbacks for commands and command
6999 replies are one and same. The pending commands are not static
7000 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
7001 in client connection context. Thus, pending commands are server
7002 connection specific as it is convenient.
7004 Changed the function silc_client_command_pending and
7005 silc_client_command_pending_del and added new function
7006 silc_client_command_pending_check. Removed the
7007 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
7010 * Added cmd_ident, current command identifier, to the client
7011 connection context in lib/silcclient/client.h to keep track on
7012 command identifiers used in command sending. Client's command reply
7013 function handling now supports the mandatory command identifiers.
7015 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
7016 funtions in client to fully support pending command callbacks.
7018 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
7019 as one of the arguments to the application in the command reply
7022 * NOTE: The FORWARDED flag is depracated. It used to be depracated
7023 before first releasing SILC but came back. Now it is removed again
7024 and should come back nomore. The FORWARDED flag was used only
7025 by the JOINing procedure by forwarding the command packet to router.
7026 Now, the JOINing procedure has been changed to more generic (due
7027 to various router environment issues) and FORWARDED is not needed
7028 anymore for anything. The protocol specification is yet to be
7031 Now, removed silc_server_packet_forward from server and the flag
7032 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
7034 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7036 * Renamed NAMES command to USERS command. The NAMES was named that
7037 due to historical reasons. Now it is renamed. Also, rewrote
7038 parts of the USERS command. The nickname list is not sent anymore
7039 by the server. Only Client ID and mode lists are sent in the USERS
7040 command. Changed this also to the protocol specification.
7042 The client now resolves the names and stuff after it receives
7043 the USERS list from the server when joining to the channel.
7045 * WHOIS and IDENTIFY commands has been changed to support multiple
7046 Client ID's per command. One can now search for multiple users
7047 in the network by sending only one WHOIS or IDENTIFY command.
7048 Changed the code and the protocol specifications.
7050 * Removed silc_server_command_identify_parse and changed that IDENTIFY
7051 uses silc_server_command_whois_parse to parse the request. */
7053 * If normal server, do not parse the WHOIS and IDENTIFY requests
7054 before sending it to the router. Saves some time.
7056 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7058 * Fixed JOIN command on client library. Wrong number of arguments
7059 used to crash the client.
7061 * Added silc_server_channel_has_global function to check whether
7062 channel has global users or not.
7064 * Added silc_server_channel_has_local function to check whether channel
7065 has locally connected clients on the channel.
7067 * The silc_server_remove_from_one_channel now checks whether the
7068 channel has global users or not after given client was removed from
7069 the channel. It also checks whether the channel has local clients
7070 on the channel anymore. If it does not have then the channel entry
7071 is removed as it is not needed anymore.
7073 * The silc_server_notify now checks on JOIN notify whether the joining
7074 client is one of locally connected or global. If it is global then
7075 the channel has now global users on the channel and that is marked
7076 to the channel entry. Also, it now saves the global client to
7077 global list who is joining and JOINs it to the channel. This is
7078 for normal server, that is.
7080 Changed silc_server_send_notify_on_channel,
7081 silc_server_packet_relay_to_channel and
7082 silc_server_packet_send_to_channel check if we are normal server
7083 and client has router set (ie. global client) do not send the
7084 message to that client, as it is already routed to our router.
7086 * Implemented LEAVE notify type handling in silc_server_notify
7089 * Tested LEAVE command in router environment successfully. Tested
7090 with two routers, two servers and two clients.
7094 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
7096 * Implemented SIGNOFF notify type handling in silc_server_notify
7099 * silc_server_remove_id now removes the client entry from all channels
7100 it has joined and thusly sends SIGNOFF notify type.
7102 * Rewrote the NAMES list generation in server by removing two excess
7103 loops. The lists are created now inside one loop.
7105 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7107 * silc_server_remove_channel_user checks now also global list
7108 for channel and client.
7110 * silc_server_new_channel_user checks now both local and global
7111 list for channel and client. Fixed a bug in client id decoding.
7112 Used to decode wrong buffer.
7114 * silc_server_channel_message checks now both local and global
7115 list for channel entry.
7117 * Tested channel joining (hence JOIN) in router environment
7118 successfully. Tested with two routers, two servers and two
7121 * Tested channel message sending in router environment successfully.
7123 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
7125 * Added silc_server_save_channel_key into server.[ch] to save the
7126 received channel key in Channel Key payload processing. It is
7127 also used in JOIN command reply handling.
7129 Equivalent function silc_client_save_channel_key added into
7130 client.[ch] into client library.
7132 * Changed JOIN command reply to send information whether the channel
7133 was created or not (is existing already) and the channel key
7134 payload. Changed protocol specs accordingly.
7136 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
7137 the request was sent by ID and not by nickname. Crashed on
7140 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7142 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
7143 now correctly save the received data.
7145 * silc_server_free_sock_user_data now notifies routers in the
7146 network about entities leaving the network.
7148 At the same time implemented functions silc_server_remove_id
7149 and silc_server_send_remove_id to receive and send REMOVE_ID
7150 packets. The packet is used to notify routers in the network
7151 about leaving entities. The ID removed will become invalid in
7154 * Added function silc_idlist_del_server into server. Removes and
7155 free's server entry from ID list.
7157 * silc_server_private_message function now checks, if we are router,
7158 that the destination ID really is valid ID, naturally.
7160 * In router when NEW_ID packet is received (for new client) the
7161 hash of the Client ID is saved in the ID Cache but the
7162 client->nickname is set to NULL, instead of putting the hash
7165 IDENTIFY command now also checks that client->nickname must be
7166 valid. If it is not if will request the data from the server who
7167 owns the client. Added new function
7168 silc_server_command_identify_check.
7170 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
7171 to set the command to already allocated Command Payload.
7173 * Tested private message sending in router environment with two
7174 routers, two servers and two clients. Fixed minor bugs and now
7177 * Fixed segfault from client's NAMES command. Used to crash if
7180 * Forwarded packets must not be routed even if it is not destined
7181 to the receiver. Changed server code comply with this.
7183 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7185 * Added `require_reverse_mapping' boolean value to ServerParams
7186 structure. If TRUE (not default) the server will require that
7187 the connecting host has fully qualified domain name.
7189 If the reverse mapping is not required and hostname could not be
7190 found the IP address is used as hostname.
7192 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7194 * Implemented version string checking to both client and server.
7195 The check is incomplete currently due to the abnormal version
7196 strings used in development version of SILC.
7198 * Changed all command functions in server to use the new
7201 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7203 * Changed char *data to unsigned char *data in ID Cache system to
7204 support binary data as ID Cache data. Changed code to support
7205 binary data in lib/silccore/idcache.c.
7207 * Renamed silc_server_packet_relay_command_reply to
7208 silc_server_command_reply as it is normal packet receiving
7209 function. Rewrote the function to accept command replys for
7210 servers and not only for clients.
7212 * Mark remote router always as registered server if we are connecting
7213 to it. Otherwise, commands sent by the router to us are ignored.
7215 * All ID List find routines now returns the ID Cache Entry pointer
7216 as well if requested.
7218 * WHOIS command works now in router environment, tested with two
7219 routers, two servers and two clients.
7221 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
7222 in router environment (as it is almost equivalent to WHOIS) but
7223 hasn't been tested thoroughly. Added new functions:
7225 silc_server_command_identify_parse
7226 silc_server_command_identify_send_reply
7227 silc_server_command_identify_from_client
7228 silc_server_command_identify_from_server
7230 * Disabled route cache adding because adding two different ID's with
7231 same IP replaces the old cache entry thus giving wrong route.
7232 The entry->router->connection is always the fastest route anyway
7233 so route cache may not be needed. Of course, new routes maybe
7234 established after receiving the ID when the entry->router->connection
7235 might not be anymore the most optimal.
7237 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7239 * Add route cache for received ID for fast routing.
7241 * Added silc_server_packet_route to route received packet on router
7242 that is not destined to us.
7244 * Renamed silc_server_get_route to silc_server_route_get.
7246 * Added id_string and id_string_len fields into SilcServer to
7247 include encoded ServerID for fast comparing without excess
7248 encoding of the ID's.
7250 * Cleaned up WHOIS command on server side. Added following static
7253 silc_server_command_whois_parse
7254 silc_server_command_whois_check
7255 silc_server_command_whois_send_reply
7256 silc_server_command_whois_from_client
7257 silc_server_command_whois_from_server
7259 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
7260 arguments in command replies. All command functions should be
7261 updated to use this macro.
7263 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7265 * Minor typo fixes on command reply handling on server.
7267 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7269 * Added silc_server_command_add_to_channel internal routine to add
7270 the client to the channel after router has created the channel and
7271 sent command reply to the server.
7273 * Added generic silc_server_send_command to send any command from
7276 * Use static buffer with ID rendering instead of duplicating data.
7278 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7280 * Fixed a channel user mode bug when joining to a channel server gave
7281 everybody channel founder rights, oops.
7283 * We mark ourselves as the router of the incoming server connection
7284 if we are router ourselves. This way we can check in some packet
7285 sending functions whether it is locally connected server. For
7286 incoming router connections we put NULL.
7288 * For router sending packets locally means now always sending the
7289 packet cell wide; to local clients and local servers. For normal
7290 server sending packet locally means sending it to only local
7293 * Fixed the JOIN command to really work in router environment. If the
7294 channel is created it is always created by the router. Router is
7295 also responsible of making the initial joining to the channel,
7296 sending JOIN notify to the sending server and distributing
7297 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
7298 does not exist server doesn't do anything else but forward the
7299 command to the router which performs everything.
7301 * Added silc_server_send_channel_key function to send the Channel Key
7304 * Added silc_server_create_channel_key to create new channel key. The
7305 channel key is now re-generated everytime someone joins or leaves
7306 a channel, as protocol dictates. Note: channel->key_len is the
7309 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7311 * Splitted server.[ch] finally. Created now packet_send.[ch] and
7312 packet_receive.[ch] to separate packet sending and receiving
7313 routines. The server.[ch] now includes everything else including
7314 actual packet processing (writing and reading data) and other
7317 Renamed silc_server_private_message_send_internal to
7318 silc_server_send_private_message. The routine is still though
7319 used only to relay private messages as server does not send
7320 private messages itself.
7322 Renamed silc_server_new_channel to silc_server_create_new_channel
7323 and added new function sicl_server_new_channel that handles the
7324 incoming New Channel packet. Added also new sending function
7325 silc_server_send_new_channel to send New Channel Payload.
7327 * Added new function silc_server_notify to process incoming notify
7328 packet to the server/router. Server may then relay the notify
7329 to clients if needed.
7331 * Added new function silc_server_new_channel_user to process incoming
7332 New Channel User packet. Router will redistribute the packet and
7333 send JOIN notify to its local clients and locally connected servers
7334 if needed. Normal server will send JOIN notify to its local client
7335 on same channel when received this packet. Added also corresponding
7336 sending function silc_server_send_new_channel_user to sent the
7339 * Added boolean route argument to send_notif_to_channel and
7340 packet_send_to_channel functions to attempt to route the packet
7341 if it is TRUE and send only locally if it is FALSE.
7343 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7345 * silc_server_replace_id now broadcasts the received replace ID
7346 packet if it is not broadcast packet already. The router must
7347 broadcast to inform other routers about changed ID.
7349 * Added backpointer to server's router into SilcServer context in
7350 silcd/server_internal.h.
7352 * Fixed silc_server_packet_broadcast to send correct broadcast
7355 * The channel key is now distributed to the local client as soon
7356 as it is received from the router (in router environment) so that
7357 no other packet may be sent for the channel until client has
7360 * silc_server_remove_channel_user now broadcasts the received
7361 Remove Channel User packet if it is not broadcast packet already.
7362 The router must broadcast to inform other routers about removed
7365 * Added users field into SilcPacketContext that is a reference count
7366 of the context. One can increase the reference count by calling
7367 silc_packet_context_dup which is now changed to just increase the
7368 reference count instead of duplicating the data. The reference
7369 count is decresed by calling silc_packet_context_free that will
7370 free the data after the reference count hits zero.
7372 For now on the packet context and everything allocated into it
7373 (including the raw packet from network) must be freed by calling
7374 the new silc_packet_context_free function. Added also new function
7375 silc_packet_context_alloc that must be used now to allocate the
7376 context. This also means that if a routine is asynchronous from
7377 silc_[client/server]_packet_parse_type the packet context must
7378 be duplicated by calling silc_packet_context_dup. Otherwise it
7379 gets free'd after silc_[client/server]_packet_parse_type returns.
7380 Also, one must remember that if packet is duplicated then its
7381 reference count must be decresed by calling the free function as
7382 many times as it was duplicated.
7384 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7385 from both client and server.
7387 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7389 * Made joining to a channel working in router environment.
7391 * Cleaned up JOIN command on server side and create function
7392 silc_server_command_join_channel internal routine to make the
7395 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7397 * Changed silc_command_pending list to SilcDList. Also, added
7398 `ident' field to SilcServerCommandPending structure to identify
7399 the reply and to call correct callback.
7401 Added silc_server_command_pending_check function to replace the
7402 corresnponding macro. The silc_command_pending list is not
7405 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7406 to set identifier to previously allocated Command Payload. It
7407 is used to set identifier for command when resending Command
7410 * Added silc_command_payload_encode_payload to encode Command
7411 Payload buffer from SilcCommandPayload structure.
7413 * Added silc_argument_payload_encode_payload to encode Argument
7414 payload buffer from SilcArgumentPayload structure.
7416 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7418 * Changed WHOIS command to support router connection on server side.
7419 The whois request is always sent to router unless the server is
7420 standalone server. After server has received the reply from the
7421 router will it send the reply to the client.
7423 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7424 broadcast received broadcast packet. The function is used only
7425 by router. The broadcast packet is always sent to the router's
7428 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7429 render given ID to printable string, for log files for example.
7431 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7433 * Made basic router to router connections working. At least they
7434 can now connect to each other but nothing really works the way
7435 they are supposed - yet.
7437 * Added new initiator token to RouterConnection configuration
7438 file in silcd/serverconfig.[ch]. It is used to tell whether we
7439 are the initiator to the remote router or whether we'll expect
7440 the other end to connect.
7442 * Moved registering of listener task to silc_server_init, hence
7443 the server starts listenning as soon as it is run, even if it
7444 does not have connections to other routers. Let's see how well
7447 * Changed default connection retry timeouts for more suitable in
7450 * Removed cipher and such arguments from silc_idlist_add_client
7451 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7452 Added new function silc_idlist_add_data to add the keys and stuff
7455 * Added SilcIDListData structure and added it to SilcClientEntry
7456 and SilcServerEntry as their first field in the structure. This
7457 way we can explicitly cast the ID entries to the SilcIDListData
7458 structure and get common data for the entries. In past, we had
7459 to first check what type of connection it is and then cast it to
7460 correct ID entry type. Now, we can directly cast the opaque
7461 pointer to the SilcIDListData (no matter what ID entry it actually
7462 is) and get the data needed.
7464 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7466 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7467 in some circumstances even if threre were timeout tasks, though not
7468 IO tasks, but tasks anyway. Now fixed.
7470 * Defined SilcServerConnection structure to hold connection specific
7471 stuff about directly connected servers and routers. The definition
7472 is currently in silcd/server_internal.h. I thought about having
7473 a bit more important role fro this struct but for now it is used
7474 only when connecting to other server (or router actually).
7476 * Added connecting retry support in server when connecting to
7477 router(s). The retry feature implement exponential backoff
7478 algorithm. Also, added SilcServerParams structure to hold default
7479 parameters for server. For now, it include these retry settings
7480 and are hard coded. After server is moded to be as Silc Server
7481 Library this structure will be more important.
7483 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7485 * Changed client librarys channel->clients table to SilcList and
7486 changed code accordingly.
7488 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7490 * Changed client's channel table to SilcList and changed code
7491 accordingly. Also changed SilcChannelClientEntry to include back-
7492 pointer to the channel so that client entry can use that structure
7493 as list as well and we have fast cross-reference to the channel.
7494 This change dramatically decreased the complexity of channel
7495 handling with client entry and vice versa (removed one extra
7496 loop when searching for channel entry from many functions).
7498 * Changed server->sim from table to SilcDList and changed code
7501 * NAMES command can now be used from user interface. It will show
7502 the user list on the channel, neatly.
7504 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7505 Code now saves realname of the user if it becomes available.
7507 * Renamed configure.in to configure.in.pre and made ./prepare
7508 script to automatically add correct version string to
7509 configure.in which it creates from configure.in.pre.
7511 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7513 * NAMES command reply now shows users mode with the nickname when
7516 * Moved silc_client_ch[u]mode[_char] functions from
7517 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7518 place sucks, they are utility functions and should be in some
7521 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7523 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7526 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7530 * Added TRQ (efficient deque and list library) into lib/trq. This is
7531 a very good list library that is currently used in the SILC. Defined
7532 SilcList API over the library because I didn't like the API very
7533 much. See lib/trq/silclist.h for the API and examples of how to
7534 use the API. Fixed various places in the code to use the new
7535 SilcList API. The SilcList is meant for lists that has a structure
7536 already defined as a list. It is not suitable to add just some
7537 context to the list (in TRQ, the context is the list actually).
7539 So, I defined SilcDList that can be used for the purpose where
7540 predefined list structure does not exit. This can be used as
7541 such list. Now some context just can be added to the SilcDList.
7542 Currently this list is not used in the SILC just yet, though there
7543 are a lot places where this can replace dynamically allocated
7544 tables and I will fix these places, later, to use SilcDList.
7545 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7546 and use TRQ internally).
7548 Also fixed some annoying warning messages that the original TRQ
7549 code generated. Also minor changes to TRQ's Makefile.in.
7551 * Added support for querying by Client ID to both WHOIS and
7552 IDENTIFY commands into server, as required by the protocol.
7554 * Removed method function pointers from SilcBuffer structure. They
7555 weren't used to anything and just increased the context size for
7556 no good reason. This change also made silc_buffer_alloc and
7557 silc_buffer_free functions inline functions.
7559 * Disabled command flooding detection support until it's fixed so
7560 that it accepts commands in but does not execute them more than once
7563 * Added silc_net_localhost(), to return local hostname, into
7564 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7565 that must be initialized before calling silc_client_init.
7567 * Added new function: silc_server_send_notify_on_channels to send
7568 notify messages to all channels client has joined. It is assured
7569 that the message is sent only once per client.
7571 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7572 lib/silcutil/silcutil.[ch] as silc_format function. The new
7573 function is generic and is used by server as well, not only by
7574 the logging routines.
7576 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7577 the provided version string was not acceptable. Added new function:
7578 silc_ske_check_version into lib/silcske/silcske.h. The function
7579 must be implemented by the application (client or server) and it
7580 does not reside in the SKE library. The function checks the version
7581 string remote end sent.
7583 * Added back pointers (to opaque context and to SilcSocketConnection)
7584 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7586 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7587 duplicate packet context structure.
7589 * Changed `notify' client operation to send same arguments as client
7590 receives from server except for ID's. ID's are mapped to correct
7591 ID entry and that is returned. Also, if channel entry is not sent
7592 by server but the notify is for channel the channel entry is sent
7593 to application (otherwise application doesn't know that it is for
7594 channel (library gets it from packet's Destination ID)).
7596 * Added silc_client_remove_from_channels into client library to
7597 remove a client from all channels it has joined to. Used when
7598 received SIGNOFF notify from server. Added also new function
7599 silc_client_replace_from_channels to replace old ID entry with
7600 new ID entry on all channels. Used when received NICK_CHANGE
7603 * Fixed ID Cache list handling in silc_idlist_get_client in
7604 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7605 to get (or query) client by ID.
7607 * Updated TODO list.
7609 * Added connection authentication status message defined by the
7610 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7611 support for these into the code in client and server side.
7613 * Added generic function silc_client_send_command to send any command
7614 with variable argument list. Application should use this function
7615 to send commands if the command functions provided by the library
7616 does not suite for the application's user interface needs.
7618 * Added new `failure' client operation. Application is notified about
7619 received failure packet if client is executing a protocol. In this
7620 case the protocol's execution has failed.
7622 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7623 is required by the protocol.
7625 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7626 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7629 * Added status flag to SilcSKE object to indicate realtime status
7630 of the SKE protocol.
7632 * Application receives now exactly same command reply arguments as
7633 the library receives from server. However, if ID is received the
7634 corresponding ID entry is returned to the application (eg. Client
7635 ID is mapped to correct SilcClientEntry entry and that is returned).
7636 Changed command_reply client operation due to this change.
7638 * Changed all ID's in commands and in command replys as ID Payloads.
7639 Change affected both client and server side codes.
7641 All ID's sent in SILC network (with execption of ID's in SILC
7642 Packet header) are sent in ID Payload to support variable length
7645 * Server now notifies nick changes and notifies all clients on
7646 the channels about the new nickname (about the new Client ID,
7649 * Implemented CMODE command to change channel modes. Supports all
7650 channel modes defined by the protocol specs except ban and invite
7651 lists. (Also, private channel key mode is supported but support for
7652 setting private channel key in client is missing, thus, this mode
7653 has no effect on client side (except that server requires that the
7654 client uses private channel key and normal channel traffic does not
7657 Also, invite mode works per se, but INVITE command does not work
7658 yet correctly, so you can set channel as invite only channel but
7659 inviting clients to the channel does not work (it is yet to be
7660 thought what's the best way to do it).
7662 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7663 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7664 Implemented CUMODE command to change user's mode on the channel.
7665 Supports all modes defined by the protocol specs.
7667 * Added NAMES command reply to return users modes on the channel.
7669 * Removed unnecessary and slow ciphers from lib/silccrypt.
7671 * Set SO_KEEPALIVE option to connection sockets by default.
7673 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7675 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7676 redefined the Notify Payload into protocol specs.
7678 * Added silc_id_payload_parse_id to get ID directly from raw
7681 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7683 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7684 accept searching by Client ID as well.
7686 * Added support for LEAVE and SIGNOFF notify types in client library.
7688 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7689 to parse ID Payload from raw data.
7691 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7693 * Added flags parameter into silc_ske_assemble_security_properties
7694 function in lib/silcske/silcske.[ch].
7696 * Changed notify client operation to fit better for notify messages
7697 sent by server. The notify payload received from server is now
7698 passed to the application (after parsing it to SilcNotifyPayload).
7699 It is application's responsibility to retrieve the arguments
7700 from the payload and show the message the way it wants. The message
7701 sent by server is implementation specific.
7703 * Changed public keys to comply with the protocol specification.
7704 Old public keys are not supported anymore and are not compatible.
7706 * Removed nickname from Channel Payload as the latest draft removed
7707 it. The client must resolve the nickname from the NAMES command
7708 reply received when it joined the channel.
7710 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7712 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7714 * Fixed some errors in protocol specification drafts.
7716 * Created lib/silccore/silcnotify.c to implement Notify Payload
7717 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7718 generic payloads described by protocol specifications. The file
7719 includes implementations for ID Payload and Argument Payload.
7721 * Changed Command Payload implementation to use the new Argument
7722 Payload. Changed command_xxxx_payload to command_payload_xxxx
7723 to comply with SILC coding conventions.
7725 * Added suppport for Argument Payload handling in Notify Payload
7726 implementation as protocol requires it. Added the new support
7727 into server and client lib as well.
7729 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7731 * Added support for multiple nicknames on same channel. [n] is
7732 added locally to the nickname if there are more than one same
7733 nicknames on the channel.
7735 * Server now sends all nicknames that matched WHOIS request.
7736 Client also shows the list received from server.
7738 * Added TOPIC command to client side. User can now set and show
7739 current topic on channel.
7741 * Added MOTD command to client and server. Also, server sends the
7742 motd when client connects to the server.
7744 * Changed version strings to comply ISO 8601.
7746 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7748 * Fixed protocol error handling in client library. It should now
7749 cope even if the SKE fails for some reason.
7751 * Made new protocol specification drafts for submitting to IETF.
7753 * Implemented TOPIC command to server in silcd/command.c.
7755 * Added two new notify types into lib/silccore/silcnotify.h:
7756 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7757 notify nickname change and topic setting/change on a channel.
7759 * API change of command_reply operation in client library. The
7760 application gets now the status type received from server as well.
7762 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7764 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7766 * Cras fixed and optimized the packet handling even further and
7767 it should work now. Minor change to the prototype of function
7768 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7770 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7772 * Added new function into lib/silcutil/silcschedule.[ch]:
7773 silc_schedule_with_fd to select() a specified fd. The function
7774 returns after timeout expires or data arrives or goes. The
7775 function is used by packet routines to wait that all data is
7776 received from network.
7778 * Fixed data reading from network in lib/silccore/silcpacket.c.
7779 The code now assures that all data is read from the fd and then
7780 continues packet processing. This was a bug fix since the code
7781 used to drop some data in some circumstances.
7783 * Added new function into lib/silcclient/client.[ch]:
7784 silc_client_start_key_exchange to start key exchange after
7785 connection has been established to server. The code internally
7786 now uses this funtion but its main purpose was to provide it
7787 for applications that perform their own connecting. After
7788 application has created a connection it merely calls this
7789 function to start the key exchange between client and server.
7790 The library takes care of everything else after that.
7792 Updated also lib/silcclient/README to explain the usage of
7795 * Do not send to application information that connection has
7796 been established. Application gets notified it by connect
7799 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7801 * Applied cras's patch to add silc_schedule_one function. The
7802 function runs scheduler once and returns.
7804 * Fixed the scheduler after cras messed it up. The timeout
7805 handling works now as it's supposed to work.
7807 * Added into lib/silccore/ silcnotify.h to include notify
7808 message types support. Changed silc_server_send_notify*
7809 functions, in server.[ch], to support those new notify types.
7810 Added the support for the notify types into client library,
7811 as well. Added new notify client operation into ops.h in
7814 * Changed silc_server_packet_send_to_channel to send normal
7815 packets instead of just channel message packets. The function
7816 is now used to send the notify packets to channels. It is not
7817 used to send channel message packets anymore, as server never
7820 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7821 va_arg()s as it seems to require it nowadays. I guess, if SILC
7822 is compiled with older va_arg() the new code should work anyway.
7824 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7826 * Splitted core library. Core library (lib/silccore) includes
7827 now only SILC protocol specific core (and common) components.
7828 Created new utility library (lib/silcutil) that includes more
7829 generic purpose stuff. The stuff for util library was taken
7830 from the old core library. This was minor and easy split.
7832 * Created SILC Client Library (lib/silcclient) that includes
7833 implementation of the SILC client without user interface. This
7834 was major move from silc/ directory. The code has been changed
7835 so that it is transparent towards the user interface. The
7836 silc/ directory includes now the same user interface as before
7837 and it uses the new client library. Read lib/silcclient/README.
7838 Basicly, the client library performs everything else related
7839 to SILC except user interface handling. Also, configuration
7840 files are considered to be part of user interface and library
7841 does not handle them.
7843 This change also changed a lot of structures, function naming etc.
7844 Most important change was that SilcClientWindow object was
7845 renamed to SilcClientConnection in the client library. Created
7846 also new file lib/silcclient/ops.h. Also added new files
7847 silc/local_command.[ch] and silc/client_ops.[ch].
7849 All these changes were made to make it easier for user interface
7850 designers to create what ever user interface for the SILC client
7853 It is also expected that the server will be moved to lib
7854 directory as well and SILC Server Library will be created;
7855 sometimes in the future.
7857 * Removed Local commands from lib/silccore/silccommand.h as
7858 they are application specific and new client library does not
7859 handle any of those anymore.
7861 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7862 old client implementation in silc/.
7864 * Added support for callback functions in SILC_LOG_* macros.
7865 Application can now set its own callbacks that will be called
7866 instead of using the default functions that will always print
7867 the debug messages to stderr (or stdout). Also, debugging can
7868 now be disabled by setting silc_debug to FALSE and re-enabled by
7869 setting it to TRUE. Note, that logging will still work even
7870 if debugging is disabled.
7872 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7873 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7874 silc_log_reset_debug_callbacks.
7876 * To enable debugging in silc client one must give now -d
7877 option on command line.
7879 * Changed silc_schedule_init to automatically allocate task queues
7880 if they are not allocated before calling it.
7882 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7884 * Added GMP 3.1 into math library.
7886 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7888 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7889 a channel in SILC network. The packet is used by servers and
7890 routers to notify other routers that user has left a channel.
7891 This little feature was missing until now. Added the feature
7892 to protocol specification as well.
7894 Added functions: silc_server_send_remove_channel_user and
7895 silc_server_remove_channel_user into server.[ch].
7897 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7898 lib/silccore/silcpacket.h. However, they are not implemented
7901 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7903 * Fixed joining to a channel and sending channel messages
7904 between server and router. The channel message sending should
7905 now work inside a cell.
7907 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7909 * Fixed the private message sending between server and router.
7910 The private message sending should now work inside a cell.
7912 * Added silc_server_replace_id into server.[ch] to replace
7913 existing ID in the SILC network.
7915 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7916 and silc_idlist_replace_server_id into idlist.[ch] in server.
7918 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7920 * Fixed the server to server connections. Server can again now
7921 connect to router. Router to router connections probably does
7924 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7926 * Added dynamic protocol registering support. Now protocols can
7927 registered and unregistered on the fly. Patch by cras.
7929 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7931 * Added lib/contrib directory to hold routines that some platforms
7932 don't have but are needed by SILC.
7934 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7935 into lin/contrib to provide getopt() and getopt_long() for
7936 those who don't have it.
7938 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7940 * Added AWAY command to client. When away message is set and
7941 client receives a private message packet the client automatically
7942 replies to the sender with the away message.
7944 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7945 bug seemed to be the cause of recent problems when compiling
7948 * Added version detection support to SKE protocol specification
7949 and added the new changes to the SKE implementation as well.
7950 There were other minor changes in the SKE protocol as well.
7952 Many changes in lib/silcske/silcske.[ch] and in
7953 lib/silcske/payload.[ch].
7955 * Added ^U functionality, clear input line. Patch from cras.
7957 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7959 * Mainly small bugfixes on core library. Fixed some debugging
7960 logging and buffer overflow in silclog.c.
7962 * Updated config.sub and config.guess on the distribution tree.
7964 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7966 * Added command lagging support in server. Client may execute
7967 commands now only once in two seconds.
7969 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7971 * Optimized packet reception. MAC computation and checking is now
7972 also more optimized. A lot previously duplicated code is now
7973 used as generic by both client and server.
7975 * Fixed key pair generation in clientutil.c
7977 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7979 * Added into lib/silccore/silcbufutil.[ch] new function;
7980 silc_buffer_realloc.
7982 * Moved generic packet sending/encryption functions to
7983 lib/silccore/silcpacket.[ch] from client and server. Some
7984 rewriting of the functions.
7986 * Moved all generic packet reception/decryption functions to
7987 lib/silccore/silcpacket.[ch] from client and server. The
7988 packet processing is now much cleaner in both client and server.
7989 These were major changes in both client and server.
7991 * Created many common functions in server to do packet sending.
7992 Previously code were duplicated a lot, this has been removed
7995 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7997 * Rewrote major parts of the ID cache system. Don't know
7998 whether it is better now or not but at least the API is more
8001 * Major rewrite on ID cache stuff on client because of the ID
8002 cache API changes. Added idlist.c to client.
8004 * Also major rewrite on ID cache stuff on server as well.
8005 Major rewrite of idlist.[ch]. SilcXXXList's are now named
8006 SilcXXXEntry's. We won't keep anymore idlist specific pointers
8007 in hand, instead they are all put into the ID cache system now.
8008 All server_idlist_* routines uses ID cache now instead of
8009 traversing its own lists (those lists does not exist anymore).
8010 SilcIDList though still exists. Also, SilcXXXEntry's are
8013 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8015 * Finally made the SKE implementation compliant to the protocol
8016 specification. All mp integers are now binary encoded as
8017 opposed being HEX encoded.
8019 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
8022 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
8023 functions: silc_[encode/decode]_pem. Also added function
8024 silc_encode_pem_file to PEM encode with newlines ('\n') for
8027 * SILC public keys are now encoded either PEM or binary. Same
8028 option is for private keys as well. By default private keys
8029 are binary encoded and public keys PEM encoded. Silly HEX
8030 encoding were removed.
8032 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
8033 function to create fingerprints.
8035 * Fixed a bug in SHA1; does not change the original data anymore.
8037 * Partly implemented INFO command on client and server side.
8038 Fixed CLEAR command. Changes to SERVER command; show current
8039 server(s) when giving command without arguments. Added
8040 VERSION command to client.
8042 * Added check to server that unregistered connections cannot
8043 execute commands (unless it is specificly allowed).
8045 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8047 * Fixed screen refresh.
8049 * Fixed channel joining bug from client. On some circumstances
8050 client tried to join to a channel it had already joined.
8052 * Added public key verification process into client's protocol.c.
8053 The client now verifies the public key from user and saves
8054 it into ~./silc/serverkeys/ directory.
8056 Added into: clientutil.[ch]: silc_client_verify_server_key.
8058 * Changed SKE protocol's silc_ske_initiator_finish function
8059 to accept callback function that verifies the received public
8060 key. Removed old silc_ske_verify_public_key function.
8062 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8064 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
8065 silc_pkcs_private_key[_data]_set.
8067 * Made the password and public authentication more cleaner in
8068 server's protocol.c.
8070 * Removed historic and obsolete protocol `channel_auth' from
8071 both client and server.
8073 * Removed wrong way of sending command status messages from
8074 server to client in server's command.c. The old way violated
8075 protocol specification.
8077 Changes to silccore/silccommand.[ch]: removed
8078 silc_command_encode_status_payload -> not needed anymore,
8079 changed silc_command_encode_payload_va to accept extra
8080 argument on variable argument list. The argument type must
8081 now be provided to the function. Also, added new function:
8082 silc_command_encode_reply_payload_va which is same as
8083 normal command_encode_payload_va except command status type
8084 is provided as extra argument.
8086 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8088 * Added ~./silc directory handling. The directory includes the
8089 public and private keys for the client.
8091 Added silc_client_check_silc_dir, silc_client_create_identifier
8092 and silc_client_load_keys.
8094 * Implemented SILC protocol compliant public key. Added public
8095 and private key saving to and loading from files.
8097 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
8098 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
8099 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
8100 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
8101 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
8103 Implemented: silc_pkcs_save_[public/private]_key[_data] and
8104 silc_pkcs_load_[public/private]_key.
8106 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8108 * Added silc_server_get_route (route.[ch]) to get connection
8109 data for the fastest route for given ID.
8111 * Implemented INVITE command on client and server. The command
8112 were re-defined in the SILC Protocol Specification and the
8113 implementation now complies with the specification.
8115 * Implemented PING command on client and server.
8117 * Implemented NAMES command on client and server. The server side
8118 supports currently only normal server not router server yet.
8119 Some changes to NAMES definition in SILC protocol specification.
8121 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8123 * Implemented LEAVE command on client and server.
8125 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
8126 again. This change was made to the protocol as well. Server
8127 should not violate the protocol specification anymore.
8129 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
8131 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
8132 was tested. SOCKS4 was not but should work anyway.
