1 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Found the reason of random crashes in the server. We weren't
4 ignoring the SIGPIPE signal (which can be sent in write())
5 and it crashed the server. Affected file silcd/silcd.c.
7 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
9 * Assure that sock->user_data is not NULL in the function
10 silc_server_packet_send in silcd/packet_send.c.
12 * Disconnect the remote connection if it could not be added
13 to any ID lists in the server. The affected file is
16 * Check in silc_server_packet_send[_real/dest] that the
17 socket is not disconnecting and ignore the data if it is.
18 Affected file silcd/packet_send.c.
20 * Define inline to __inline on native WIN32 compilation.
21 Affected file includes/silcwin32.h.
23 * Added some explicit type casts for inline code since MSVC
24 require them. Affected files lib/silcutil/silcbuffer.h,
25 lib/trq/silcdlist.h and lib/trq/silclist.h.
27 * Print warning in log files from now on if the packet
28 decryption fails. Affected file silcd/server.c.
30 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
32 * Changed the `say' client operation's interface to accept
33 new `type' argument to indicate the type of the message sent
34 by the library. The application may filter the library's
35 messages according the type. The affected file is the
36 lib/silcclient/silcapi.h.
38 * Added two new functions to lib/silcclient/silcapi.h:
39 silc_client_del_client and silc_client_del_client_by_id.
40 Affected file lib/silcclient/idlist.c.
42 * Moved the clientincludes.h from includes/ to silc/ and
43 serverincludes.h from includes/ to silcd/.
45 * The modes for the CMODE and CUMODE are now passed as
46 uint32 for application with COMMAND_REPLY. The affected
47 file is lib/silcclient/command_reply.c.
49 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
51 * /WHOIS without arguments shows client's own information.
52 Affected file lib/silcclient/command.c.
54 * Changed PING to not accept any arguments. The specs
55 says that client can ping only the connected server so
56 requiring an argument is not needed. Affected file is
57 lib/silcclient/command.c.
59 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
61 * Fixed a fatal bug in private message sending and reception
62 encryption and decryption when using private message keys.
63 The implementation was incorrect and did not follow the
64 specification. It causd that some of the message were
65 lost since it did not use the sending and receiving keys
66 as the protocol suggests. This has been fixed and will cause
67 incompatibilities with older clients when sending private
68 message encrypted with private message keys. Affected files
69 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
70 and various other in Irssi SILC Client.
72 Added `responder' boolean argument to the functions
73 silc_client_add_private_message_key[_ske] to indicate when
74 the key is added as responder or initiator of the key
77 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
79 * Removed the silc_ske_check_version function and created
80 a SilcSKECheckVersion callback. Added also a function
81 silc_ske_set_callbacks that is now used to set all SKE
82 callbacks. The callback functions are not given to
83 the SKE functions anymore, but this function is used to
86 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
88 * Added `silc_version' argument to the silc_client_alloc
89 to define the version of the application for the library.
90 The library will use the version string to compare it
91 against the remote host's (usually a server) version
92 string. Affected file lib/silcclient/silcapi.h
94 * Added the KE protocol context to Key Agreement context
95 in client library so that we can abort the SKE if it
96 is in process when we get timeout. Affected file is
97 lib/silcclient/client_keyagr.c.
99 * Do not resolve the client ID forever if it returns in the
100 first time that such client does not exist. This was done
101 for example with private message. Affected file is
102 lib/silcclient/client_prvmsg.c.
104 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
106 * Do not add regex.h for WIN32. The affected file
107 includes/silcincludes.h.
109 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
110 not work yet 100%. It generates the DLL's automatically
111 when compiling with --with-win32 under cygwin.
113 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
115 * lib/contrib/regex.c is not compiled on WIN32.
117 * Added silc_net_get_socket_opt function to the
118 lib/silcutil/silcnet.h.
120 * Added includes/silcwin32.h for WIN32 specific includes
123 * Do not use ptime structure or any of the posix process
124 functions on WIN32 in lib/silccrypt/silrng.c.
126 * Added silc_gettimeofday to provide generic function
127 for struct timeval on all platforms. Added the function
128 to lib/silcutil/silcutil.h.
130 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
132 * Moved the lib/silccore/silcsockconn.[ch] to the utility
133 library as they clearly belong there. As a plus side we
134 can make the actual socket connection routines platform
137 Added also new generic function silc_socket_read and
138 silc_socket_write (that used to be silc_packet_[read/write].
139 The implementation of these are platform specific.
141 * Added WIN32 specific routines of silc_socket_[read/write]
142 to lib/silcutil/win32/silcwin32sockconn.c.
144 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
146 * Added preliminary support for native WIN32 compilation under
147 cygwin (using the -mno-cygwin option for GCC) to the
148 ./configure.in.pre. The --with-win32 now prepares the
149 compilation for native WIN32.
151 * Rewrote the SILC Scheduler interface in the file
152 lib/silcutil/silcschedule.h. The scheduler is now context
153 based and does not have anymore any global static scheduler.
154 Moved the Unix scheduler to the lib/silcutil/unix/ directory
155 and created lib/silcutil/win32 directory for WIN32 based
158 * Added Unix specific network routines to the
159 lib/silcutil/unix/silcunixnet.c and the old
160 lib/silcutil/silcnet.c includes now only generic routines.
162 Added WIN32 specific network routines to the
163 lib/silcutil/win32/silcwin32net.c.
165 * Added Unix specific utility functions from the
166 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
168 * Added WIN32 SILC Scheduler to the file
169 lib/silcutil/win32/silcwin32schedule.c. The code is of course
172 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
174 * Do not handle JOIN notify in the server if the target client
175 is not registered (idata->registered == FALSE). The affected
176 file is silcd/packet_receive.c.
178 * Update the nickrec->founder in event_cumode in the Irssi SILC
179 client. Affected file irssi/src/silc/core/silc-channels.c.
181 * Fixed the CUMODE_CHANGE notify handling in the server when
182 server and router are announcing their clients on channels.
183 Now the mode changes are saved and notified correctly. The
184 affected file is /silcd/packet_receive.c.
186 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
187 They really did not replace the cache entry in the ID Cache.
188 Now they do that. Affected file silcd/idlist.c.
190 * Fixed the KICK notify handling in the Irssi SILC client to
191 update the channel records so that the kicked client does not
192 appear to be on the channel. The affected file is
193 irssi/src/silc/core/silc-channels.c.
195 * Always update the conn->current_channel when executing command
196 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
198 * Fixed the KILL notify handling in Irssi SILC client to remove
199 the killed client on all channels.
201 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
203 * Fixed the silc_parse_command_line to remove extra spaces
204 from the start and end of the arguments. Affected file is
205 lib/silcutil/silcutil.c.
207 * Cancel and free any active protocol in the function
208 silc_server_close_connection. Affected file silcd/server.c.
210 * Cancel and free any active protocol in the function
211 silc_client_close_connction. Affected file is
212 lib/silcclient/client.c.
214 * Do not execute the KILL command for clients that are in
215 history (ie. they are not in the network). Affected file is
218 * Fixed KILL notify handling, client does not crash anymore.
219 Affected file irssi/src/silc/core/silc-channels.c.
221 * Reduced the default packet buffer size from 2048 to 1024 in
222 lib/silccore/silcpacket.c.
224 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
225 counter to the SKE context that is incresed when the SKE library
226 performs async operation outside the library. If the outside
227 process frees the SKE context and FREED status will be set
228 and the library will detect after the sync operation that the
229 libary is freed. The affected files are
230 lib/silcske/silcske[_status].[ch].
232 * Resolve the client entry information in the function
233 silc_client_channel_message to assure that NULL pointer is not
234 passed as client entry to the application. */
236 * Fixed the task timeout calculation to assure that there is
237 never negative timeouts. The affected file is
238 lib/silcutil/silcschedule.c.
240 * Fixed the channel user mode notification sending in server.
241 It was sent point-to-point to the router (or to server by router)
242 but it needs to be destined to a channel. The routines now
243 supports sending the channel user mode notifys to the channels
244 when announcing clients and channels. Affected files are
245 silcd/server.c and silcd/packet_receive.c.
247 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
248 It did not actually replace the old channel entry in the cache.
249 Affected file lib/silcclient/client_notify.c.
251 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
253 * Fixed a possible crash in silc_packet_send_prepare. It now
254 assures always that there is enough space in the buffer and
255 at the tail area of the buffer (for MAC).
257 Fixed the inbound buffer reallocation in silc_packet_read.
258 It was old code and did not handle the reallocation correctly.
261 The affected file is lib/silccore/silcpacket.c.
263 * Fixed buffer overflow in silc_parse_nickname in the file
264 lib/silcutil/silcutil.c.
266 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
268 * make install generates new server keys only if there is not
271 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
273 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
274 Added check that if the NOREPLY is set then we will not send
275 the away message. This avoids infinite loop of away messages
276 if both clients are away. The affected file is
277 lib/silcclient/client_prvmsg.c.
279 * Fixed client crash if /NICK was given without arguments.
280 Affected file lib/silcclient/command.c.
282 * Server does not send the invite list in INVITE command back
283 to the client if the list was not altered. Added this notion
284 to the protocol spec as well. Affected file silcd/command.c.
286 Fixed possible crash in INVITE command by checking the
287 value of silc_server_get_client_route command.
289 * Fixed the INVITE notify type handling. The arguments are now
290 taken in correct order and client does not crash. The affected
291 file is irssi/src/silc/core/silc-channels.c.
293 Removed the "Inviting xxx to channel" message from the
294 client library away and let the application handle it.
295 Affected file lib/silcclient/command.c. Added that message
296 to Irssi SILC client's message formats.
298 * Fixed CMODE command crash in client. It now checks the
299 amount of arguments correctly and does not crash. The affected
300 file is lib/silcclient/command.c.
302 * Do not create new channel automatically in silc_channels_join
303 but check whether the channel by that name already exists.
304 Affected file irssi/silc/core/silc-channels.c.
306 * Do not send the SERVER_SIGNOFF to router if the disconnected
307 entity was the router. Affected file silcd/server.c.
309 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
310 SILC client as it was missing from there.
312 Added the handling of the KICK notify to the Irssi SILC client
313 as it was missing. Added "you have been kicked" message to
314 Irssi SILC client's message modules formats.
316 Added the handing of the KILL notify to the Irssi SILC client
317 as it was missing. Added the kill message module formats
320 The affected file is irssi/src/silc/core/silc-channels.c.
322 * The router did not save the channel mode the server announced.
323 Affected file silcd/packet_receive.c.
325 * Fixed a possible crash in INFO command in server. If the
326 server did not provide the server info it crashed. Affected
327 file silcd/command.c.
329 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
331 * Fixed the GETKEY command in the server to check also the
332 global list. Otherwise the GETKEY would not work correctly
333 in normal SILC server. Affected file silcd/command.c.
335 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
337 * Fixed GETKEY crash, it crashed if the command did not succseed.
339 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
342 is now real and not just an macro interface to GMP.
344 Removed the entire GMP from the source tree and imported new
345 NSS MPI library instead. Reason for removing GMP is that it is
346 extremely large and compiles extremely slow. The NSS MPI
347 is only a few files and compiles in less than 10 seconds.
348 The speed is also about the same as GMP. The MPI is imported
351 If the system has GMP installed we will still use the GMP.
352 If it is not then the NSS MPI will be compiled.
354 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
356 * Merged a long nickname (127 characters long) crash bugfix from
357 Irssi CVS tree. Affected file irssi/src/core/misc.c.
359 * Merged a freed memory reference bugfix from Irssi CVS tree.
360 Affected file irssi/src/core/commands.c.
362 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
364 * Added the server's public key sving and verification to the
365 server when performing the SKE. This was missing and the
366 remote server's (or router's) public key was accepted without
367 checking whether we have it previously or trust it at all.
368 Affected file silcd/protocol.c.
370 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
372 * Check in the silc_server_timeout_remote if protocol is active
373 and make sure that the protocol's final callback is called so
374 that all memory if freed. Affected file silcd/server.c.
376 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
378 * silc_server_whois_send_reply crashed the server if the nickname
379 was 127 characters long. Affected file silcd/command.c.
381 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
383 * Added sanity check to the silc_server_new_client. If the hostname
384 is provided inside username then check that the provided hostname
385 really is the same as the resolved one. If the hostname was not
386 resolved then check it from the public key. Affected file is
387 silcd/packet_receive.c.
389 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
390 if the server disconnected us and the connection is not valid
391 anymore. Affected file irssi/src/silc/core/silc-channels.c.
393 * Moved the silc_client_[chmode|chumode|chumode_char] away from
394 the library to the lib/silcutil/silcutil.[ch].
396 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
398 * Close log file after open. Affected file
399 lib/silcutil/silclog.c.
401 * Check whether sock == NULL in silc_client_send_packet and return
402 if it is. Affected file lib/silcclient/silcclient.c.
404 * Check rec->entry == NULL in the Irssi SILC Client before
405 sending the channel message. Affecte file is
406 irssi/src/silc/core/silc-servers.c.
408 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
410 * Merged a splitted window bugfix from Irssi CVS tree. The
411 affected file is irssi/src/fe-text/textbuffer-view.c.
413 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
414 It did not print nickname.
416 * Improved the distributions system a bit.
418 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
420 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
421 irssi/src/fe-text/gui-window.c.
423 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
424 to in-active server. The affected file is
425 irssi/src/silc/core/client_ops.c.
427 * Resolve the client in USERS command reply if the entry does
428 not have username resolved. The affected file is
429 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
430 command to WHOIS command to really resolve stuff. The USERS
431 is not used any more in any critical section so WHOIS can
432 be used even though it might be slower than IDENTIFY.
434 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
437 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
439 * Changed the protocol API a bit more consistent in the
440 lib/silccore/silcprotocol.[ch].
442 * Changed the following headers to ROBODoc format:
444 lib/silccore/silcpayload.h
445 lib/silccore/silcprotocol.h
446 lib/silccore/silcsockconn.h
448 All core library headers are now formatted.
450 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
452 * Fixed a bug in Irssi SILC client; do not show that you are
453 server/router operator if you really are not. Affected file is
454 irssi/src/silc/core/client_ops.c.
456 * Renamed silc_command_free_payload to silc_command_payload_free.
457 Affected file lib/silccore/silccommand.h
459 * Added silcmath.h to include the prototoypes of various routines
460 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
463 * Changed the following headers to ROBODoc format:
465 lib/silccore/silcchannel.h
466 lib/silccore/silccommand.h
467 lib/silccore/silcid.h
468 lib/silccore/silcidcache.h
469 lib/silccore/silcmode.h
470 lib/silccore/silcnotify.h
471 lib/silccore/silcpacket.h
472 lib/silcmath/silcmath.h
474 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
476 * Added checking to the server code not to start the server if
477 ciphers and stuff are not configured properly. Affected files
478 silcd/serverconfig.[h] and silcd/server.c.
480 * Changed the layout of the header files of the public interfaces
481 in the SILC libraries. The new layout supports ROBODoc
482 documentation tool (and some others) so that it is easy to create
483 a library reference manual. All the other headers and source
484 code must still follow the CodingStyle document. Also source
485 code must not include these ROBODoc stuffs, only the headers.
486 Furthermore, all public interface headers must now be named
487 by using `silc' prefix, example: silcapi.h, silccipher.h.
488 Some files were renamed due to this. All the other headers
489 must not be used as public interfaces. I will update the
490 CodingStyle document later. Changed following headers, so far:
492 lib/silcclient/silcapi.h
493 lib/silccore/silcauth.h
494 lib/silccore/silcprivate.h
495 lib/silccrypt/silcdh.h
497 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
501 * Removed silc_client_packet_send_flush from the client library
502 as it is not needed. Affected file lib/silcclient/client.[ch].
504 * Added printing of message of unresolved authentication method
505 to the Irssi SILC client. Added it to the module formats.
506 Removed the same message from the client library.
508 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
510 * Added new distribution feature, DISTLABEL. Every distribution
511 can define own preprocessor label that can be used in the
512 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
513 file distributions, acconfig.h.pre and prepare.
515 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
517 * Added Makefile.defines_int to include the actual definitions
518 for Makefile.defines.in. Tested the new distribution system,
519 created distributions and tested installation.
521 * Added AWAY message printing to the Irssi SILC client. Added
522 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
524 * Added SCONNECT command to call the SILC's CONNECT command.
525 Cannot use CONNECT directly since Irssi uses that internally.
526 Affected file irssi/src/silc/core/silc-servers.c.
528 Added ACTION local command. It is same as ME command but takes
529 the channel as mandatory argument.
531 Rewrote some of the Irssi's help files to suite for SILC
534 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
536 * Added Makefile.defines[.in] that should for now on be included
537 in all Makefile.am file in the source tree. That file includes
538 all common compilation definitions for SILC source tree.
540 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
542 * Minor changes to the ./prepare script to change the package
543 name according the distribution name to the configure.in.
545 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
547 * Created new distribution system. Added file `distributions'
548 that defines all the distributions that can be created out of
549 the SILC source tree. The ./prepare script now reads that
550 file to determine how to prepare the distributions. The
551 first argument to the ./prepare is the name of the distribution
552 and second is the version of the distribution. If given
553 without arguments it creates the default (toolkit) distribution
554 with the default version (defined in ./prepare).
556 All Makefile.am files that are subject to the distributions
557 are now named as Makefile.am.pre. These are ./Makefile.am
558 and lib/Makefile.am. Others may be changed later.
560 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
562 * Added invite list, ban list, some key management and connection
563 error message printing to module formats in the Irssi SILC client.
565 * Added new silc_client_set_away_message to set the away message
566 that is back to the person who sent private message. The
567 affected file lib/silcclient/silcapi.h and the
568 lib/silcclient/client_prvmsg.c.
570 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
572 * Fixed the private message sending in the Irssi SILC client,
573 added local command KEY to the Irssi SILC client.
575 Added key management and key agreement message formats to the
576 irssi/src/fe-common/silc/module-formats.[ch].
578 Added USERS (alias WHO) printing, server/router operator
579 indication and LIST command printing to the module formats.
581 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
583 * Fixed channel joining notify handling, cumode notify handling
584 from Irssi SILC client.
586 * Added SILC specific module-formats to the Irssi SILC client so
587 that SILC specific message hilighting, colors etc is possible.
588 Affected file irssi/src/fe-common/silc/module-formats.[ch].
590 Added channel mode, channel user mode, actions, notices,
591 whois and whowas printing to the the module-formats.c.
593 * Fixed a bug in channel deletion in the server. The channel
594 is not left to the cache even if the channel founder auth mode
595 is set when there are no users anymore on the channel. Affected
598 * The silc_net_localhost now resolves the entire hostname including
599 the domain name. Affected file lib/silcutil/silcnet.c.
601 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
603 * Changed the ask_passphrase client operation to be ascynchronous.
604 It has now a completion callback and a context that the
605 application must call after it has got the passphrase from
606 the user. Affected files lib/silcclient/silcapi.h,
607 lib/silcclient/protocol.c, lib/silcclient/command.c and
610 Added SilcAskPassphrase callback that the application calls
611 to deliver the passphrase to the library.
613 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
614 The public key verification and especially a certificate
615 verification is asynchronous procedure.
617 Added new SILC_SKE_STATUS_PENDING status to indicate the
618 request is pending and a callback will be called to finalize
621 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
622 indicate that remote end did not send its public key (or
623 certificate), even though we require it. Added check for this
624 condition in the SKE. This was a security bug, now fixed.
626 Defined new SilcSKEVerifyCbCompletion callback that is called
627 when the verification process is completed.
629 The affected files lib/silcske/silcske_status.h and
630 lib/silcske/silcske.[ch].
632 * Changed the verify_public_key client operation to be async
633 as well. Defined SilcVerifyPublicKey callback that is used to
634 indicate the success of the public key verification process.
636 Changed the server and client to use the new async client
639 * Changed the Irssi SILC client's internal scheduler to be called
640 twice as many times as it used to be. As a result the client
641 should be a bit faster now. Affected file is
642 irssi/src/silc/core/silc-core.c.
644 * Added support to Irssi SILC client of asynchronous public key
645 verification and passphrase inquiry. Affected file is
646 irssi/src/silc/core/silc-core.c.
648 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
650 * Do not say "You have left channel %s" in client library.
651 Moved it to the application. Affected files are
652 lib/silcclient/command.c and silc/client_ops.c.
654 * Fixed silc_client_get_clients. Command context was not
655 duplicated and was freed memory in the callback. Affected
656 file lib/silcclient/idlist.c.
658 * Do not say "you are now talking..." on JOIN command in the
659 client library. The appliation must handle it.
661 * Do not say ".. changed topic to" in command reply in the
662 client libary. The application must handle it.
664 * Fixed TOPIC command sending in the client library.
666 * Fixed a memory leak in silc_client_command_free in the file
667 lib/silcclient/command.c.
669 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
671 * Imported a modified version of Irssi client to the source tree.
672 The Irssi will be used to create a new client called
673 Irssi SILC. Imported to irssi/.
675 Added silc_core_init_finish function to the Irssi. Affected
676 file irssi/configure.in.
678 A lot changes in the Makefile.ams around the irssi tree.
680 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
682 * Do not rehash if the new size is same as the old size of the
683 hash table, in the silc_hash_table_rehash*. The affected file
684 lib/silcutil/silchashtable.c.
686 * Replaced hash_table_del_by_context calls from the server
687 (when channel->user_list and client->channels) to the
688 hash_table_del as it is sufficient and faster.
690 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
692 * Added silc_hash_table_list, silc_hash_table_get and the
693 SilcHashTableList structure to provide an alternative way to
694 traverse the hash table. The affected files are
695 lib/silcutil/silchashtable.[ch].
697 * Changed the server's idlist routines to use the hash table
698 routines to optimize the code.
700 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
702 * Replaced the client entry's `channel' list and channel entry's
703 `user_list' list to hash tables for optimized lookup. Changed
704 the code to use the hash table interface around the code.
705 Affected file lib/silcd/idlist.[ch].
707 * Added `auto_rehash' boolean argument to the function
708 silc_hash_table_alloc to indicate whether the hash table should
709 auto-rehash when it thinks is appropriate time. It will
710 increase the hash table size if the there is twice as much
711 entries in the table than the size of the table, and will
712 decrease the size if there are twice as less entries than
713 the size of the table.
715 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
717 * Fixed silc_xxx_get_supported to not crash at some circumstances.
719 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
721 * silc_idcache_purge_by_context deletes the entry now by context
722 as it is supposed to do. Affected file lib/silccore/idcache.c.
724 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
725 client is not anymore valid (WHOWAS givens the info) and not
726 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
728 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
730 * Removed the `data' and `data_len' arguments from the ID Cache
731 interfaces and added `name' argument. ID Cache does not handle
732 anymore the binary data only a names associated with given ID.
734 * When hashing a Client ID with silc_hash_id the entire ID is
735 not hashed anymore, instead only the hash of the Client ID is
736 hashed. This way we can access the Client ID from the cache
737 with Client ID but with the hash of the ID (which is a hash of
738 the nickname) as well without any difference in performance.
740 Added also silc_idcache_find_by_id_one_ext to do one on one
741 searching when we have the actual ID. Added also function
742 silc_hash_client_id_compare. The affected files are
743 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
745 * When hashing the name associated with a ID it is always done
746 in lowercase. This way we can access the cache without worrying
747 about case-sensitivity, even though, for example nicknames are
750 * Fixed a bug in server with channel message sending. It put
751 wrong ID type as destination ID. The affected file
754 * silc_idcache_del_by_context now deletes from all hash tables
755 by context. Affected file lib/silccore/idcache.c.
757 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
759 * Changed the client library to use the new ID Cache interface.
760 Changes around the source tree.
762 * Added silc_hash_table_rehash_ext to rehash with specific
763 hash function. Affected file lib/silcutil/silchashtable.[ch].
765 * Added silc_hash_string_compare to compare two strings in the
766 hash table. Affected file lib/silcutil/silcutil.[ch].
768 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
770 * Added new function silc_idcache_del_by_context into the
771 lib/silccore/idcache.[ch].
773 * Changed the server's ID list routines to use the new ID Cache
774 interface. Changes around the source tree.
776 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
778 * Added silc_hash_table_del[_by_context]_ext functions in to the
779 lib/silcutil/silchashtable.[ch].
781 Removed silc_hash_table_find_all* routines and added new
782 silc_hash_table_find_foreach to replace them.
784 Added silc_hash_table_replace_ext function as extended
785 replacing function. Separated the simple hash table interface
786 from the extended hash table interface in the file
787 lib/silcutil/silchashtable.h.
789 * Fixed minor bugs and changed it to use some of the new
790 hash table functions in lib/silccore/idcache.c
792 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
794 * Added new function silc_hash_table_find_all to return all keys
795 in the hash table by the specified key. As the hash table is
796 collision resistant it also makes it possible to have several
797 duplicate keys in the hash table. This function may be used to
798 find all of the keys from the hash.
800 Added user_context arguments to the SilcHashFunction,
801 SilcHashCompare and SilcHashDestructor to deliver user specified
804 Added new fuctions silc_hash_table_find[_all]_ext to do
805 extended lookup with specified hash and compare functions and
806 specified user contexts.
808 Added new function silc_hash_table_add_ext to add the key
809 with specified hash function and user context.
811 Added new function silc_hash_table_foreach to traverse all
812 entrys in the hash table. Added SilcHashForeach callback
815 Added new function silc_hash_table_del_by_context to delete
816 the entry only if the context associated with the key matches.
818 Affected files are lib/silcutil/silchashtable.[ch].
820 * Removed silc_hash_[server/client/channel]_id and added just
821 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
822 silc_hash_id_compare to compare two ID's using as the hash table
823 comparison function. Added also silc_hash_data to hash
824 binary data and silc_hash_data_compare to compare it.
826 * Removed silc_idlist_find_client_by_hash as it is not needed
827 anymore. Affected file silcd/idlist.[ch].
829 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
830 to use internally the SilcHashTable. The new ID Cache is a lot
831 faster than the old one. Some of the ID Cache interface was also
832 rewritten and obsolete and stupid functions were removed.
834 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Added entry_count field to the SilcHashTable to keep the number
837 of the entries in the table. Implemented the function
838 silc_hash_table_rehash. Added new function
839 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
841 Fixed a minor bug in silc_hash_table_free.
843 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
844 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
845 into the lib/silcutil/silcutil.[ch].
847 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
849 * Implemented a collision resistant hash table into the
850 lib/silcutil/silchashtable[ch]. See the header and the source
851 for the SilcHashTable API.
853 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
855 * Merged dotconf version 1.0.2 into lib/dotconf.
857 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
859 * Do not compile anything in lib/silcsim/* if the SIM support
860 is not enabled. The tree should now compile without problems
863 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
865 * Compiled the SILC under cygwin. Compiled and tested briefly
866 without problems. More tests needed. The SIMs didn't compile
869 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
871 * Fixed possible crash in silc_get_username in the
872 lib/silcutil/silcutil.c.
874 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
876 * Fixed a va_arg in silc/client_ops.c.
878 * Oops, RC5 routines were named AES and caused some problems
879 when not using SIM's. Affected file lib/silccrypt/rc5.c.
881 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
883 * Added new SilcIDIP structure into the lib/silccore/id.h and
884 replaced the old `ip' fields from all SILC ID's to that type.
885 This is a step towards IPv6 support.
887 The silc_id_get_len takes now the ID as an extra argument.
888 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
889 both IPv4 and IPv6 based ID's.
891 The affected files are lib/silccore/id.[ch] and other files
892 around the tree using these routines.
894 * Removed the ID length arguments in server from various
895 silc_server_send_notify_* routines -> they are not needed
898 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
900 * Fixed memory leak in silc_encode_pem_file in the file
901 lib/silcutil/silcutil.c.
903 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
905 * Check minor version as well in the SKE. Affected files are
906 silcd/protocol.c and lib/silcclient/protocol.c.
908 * Added --identifier option to the server so that an identifier
909 can be when creating the public key for the server. Affected
910 file is silcd/silcd.c.
912 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
913 lib/silccrypt/silcpkcs.c.
915 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
917 * Register default ciphers and stuff when using -C option with
918 the server. Affected file sildc/silcd.c.
920 * Put back the servers public key filename format, it is better
921 than the new one. For now, the client keys are saved with the
922 new filename format. The affected file silc/client_ops.c.
924 * Implemented the Cipher API for the rest of the ciphers that
925 did not implement it or implemented it the wrong way.
927 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
929 * Register default ciphers and stuff when using the -S option
930 in the client. Affected file silc/silc.c. Same also when
931 creating new key pair with -C option.
933 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
935 * Fixed the silc_verify_public_key client operation function to
936 save the public keys differently. The fingerprint is now
937 used as filename and not the hostname. This way also the
938 client keys are saved uniquely and not with hostnames. The
939 affected file is silc/client_ops.c.
941 * Trimmed the silc_hash_fingerprint function to remove extra
942 whitespaces from the end of the fingerprint. The affected
943 file is lib/silccrypt/silchash.c.
947 * Added silc_cipher_register_default function to register all
948 default ciphers. It can be used when configuration files
949 does not exist and the application does not want any specific
950 ciphers in any specific order.
952 The SilcDList is now used as silc_cipher_list dynamically
953 allocated cipher list. Removed the static list all together
954 and now all ciphers must be allocated to the dynamic list.
955 The silc_cipher_alloc routine was changed to check only the
958 All silc_cipher_* routines that used to return int returns
961 The affected files lib/silccrypt/silccrypt.[ch].
963 * The same thing was done to silc_hash_* as for silc_cipher_*
964 routines. Affected files lib/silccrypt/silchash.[ch].
966 * The same thing was done to silc_pkcs_* as for silc_cipher_*
967 routines. Affected files lib/silccrypt/silcpkcs.[ch].
968 Added also silc_pkcs_[un]register[_default] functions.
969 Removed the data_context from the PKCS API.
971 * Added silc_hmac_register_default function to register default
972 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
973 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
974 to unregister all hmacs at once.
976 * Register the default ciphers, hash functions, PKCSs and HMACs
977 if client's configuration file does not exist. The affected
980 * The client did not load the hash functions from the SIM
981 modules at all. Added support for this. Affected file is
984 * When decoding public key with silc_pkcs_public_key_decode, check
985 the supported algorithm only if PKCS are registered. Affected
986 file lib/silccrypt/silcpkcs.c. The same was done with the
987 silc_pkcs_private_key_decode.
989 * Fixed the SILC List routines to keep the list always in order.
990 It used to change the list's order when traversing the list but
991 not it preserves the order. Affected file lib/trq/silclist.h.
993 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
995 * Added the client library to use the SilcSocketConnection's
996 reference counter (by silc_socket_dup) to prevent the bug that
997 the socket object may be freed underneath async operation.
999 * The name resolv library checking fixes in the configure.in.pre.
1002 * Created new version of the protocol drafts for future
1003 development. The -03 drafts are the ones that will be changed
1004 in the trunk now and the -02 will remain as they are.
1006 * Send list of CUMODE notifys to the router when announcing
1007 the channel users to the router. Affected file silcd/server.c.
1008 If the router receiving channel founder CUMODE for a channel
1009 that already has channel founder it will send CUMODE notify
1010 to the sender to remove the channel founder rights from the
1011 announced client. Affected file silcd/packet_receive.c.
1013 * The CUMODE notify may now use Server ID as well as the entity
1014 who changes the mode. Updated protocool specs.
1016 * Updated INSTALL and README files.
1018 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1020 * New web pages in the http://silc.pspt.fi. The pages was
1025 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1027 * Implemented the [DenyConnectin] config section in the server.
1028 Added silc_server_config_denied_conn to check whether incoming
1029 connection is denied. Affected file silcd/serverconfig.[ch].
1031 * Do not check the ports when checking the incoming configuration
1032 data if the port is 0, meaning any. Affected file is
1033 silcd/serverconfig.c.
1035 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1037 * Fixed buffer overflow in silc_string_compare in the file
1038 lib/silcutil/silcutil.c.
1040 * Fixed double free in silc_server_command_leave in the file
1043 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1045 * Fixed the version checking in the server. Affected file is
1048 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1050 * Fixed the configuration data fetching when accepting new
1051 connections in the server. Affected file silcd/server.c.
1053 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1055 * Added `sender_entry' argument to the function
1056 silc_server_packet_relay_to_channel so that we can check
1057 whether some destination actually belongs to the same route
1058 the sender belongs (ie, we must not resend the packet to the
1059 sender). Affected file silcd/packet_send.[ch].
1061 * Added `servername' field to the SilcClientEntry in the server
1062 to hold the name of the server where client is from. Affected
1063 file is silcd/idlist.h.
1065 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1067 * Moved the channel message encrypting in the router betwen
1068 router connections from silc_server_channel_message to the
1069 silc_server_packet_relay_to_channel since we want to check
1070 whether we have anybody channel before encrypting anything.
1071 Affected files silcd/packet_[receive/send].c.
1073 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1075 * Fixed the [AdminConnection] server config section to support
1076 multiple entries. Affected file silcd/serverconfig.c.
1078 * Added support into the server to check the validity of the
1079 incoming connection before executing any KE or authentication
1082 * The connection configuration is now saved to the KE and
1083 connection auth protocol contexts and not fetched anymore in
1084 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1086 * The local hosts listenning address and port is also resolved
1087 now when starting the server. We want to have the socket object
1088 to include the real address and port for the listener. Added
1089 new function silc_net_check_local_by_sock into the files
1090 lib/silcutil/silcnet.[ch].
1092 * Fixed a broadcast bug in server -> do not broadcast if we
1095 * Fixed a routing bug. Do not route broadcast packets ever.
1096 Broadcast packets must be processed always and not routed since
1097 they may be destined to some other host than yourself and thus
1098 would get routed without no good reason. Affected file is
1101 * Added function silc_server_config_is_primary_route to check
1102 whether primary router connection has been configured (a router
1103 configuration that we are initiating). If there is not, we
1104 will assume that there is only two routers in the SILC network
1105 and we will use the incoming router connection as our primary
1106 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1108 * Changed the order of the broadcasting. Broadcast _after_ the
1109 packet has been processed not before. Affected file is
1112 * Fixed a [ClientConnection] parsing bug. The port was never
1113 parsed correctly thus resulting to port 0. Affected file
1114 silcd/serverconfig.c.
1116 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1117 argument and did not set the broadcast packet flag. Affected
1118 file silcd/packet_send.c. Fixed same bug in the function
1119 silc_server_send_notify as well.
1121 * If we receive NEW_ID packet for our own ID in the server, ignore
1124 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1128 * Removed the nickname from the Private Message Payload.
1129 Updated the code and the protocol specs.
1131 * Updated protocol specs for submitting to the IETF.
1133 * Tweaked the Random Number Generator a bit. Affected file
1134 lib/silccrypt/silcrng.c. Exported a new function
1135 silc_rng_[global]_add_noise which can be used to add more
1138 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1140 * Do not parse packets with different timeout when protocol
1141 is active -> may cause problem with rekey. Affected file
1144 * When server receives signoff notify it must not create
1145 new channel key if the client is on any channels since the
1146 sender of the signoff notify will create it.
1148 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1150 * Added printing of error messages during SKE protocol from the
1151 failure packet sent by server during SKE. Affected file
1154 * Removed the client's failure_callback handling with timeout
1155 and handle it immediately when received.
1157 * The SKE library returned wrong type in SUCCESS and FAILURE
1158 packets. They must be 32 bit MSB not 16 bit MSB.
1160 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1162 * Ok, rewrote the logic of the re-key and now it seems to work.
1163 I tested it on high traffic with frequent re-keys without
1164 problems. Added hmac_receive (and renamed hmac to hmac_send)
1165 in SilcClientConnection in lib/silcclient/client.h and
1166 in SilcIDListData in silcd/idlist.h. Also, removed the
1167 SilcPacketParserContext's cipher and hmac fields as they are
1168 not needed anymore and actually caused some problems when
1169 the ciphers and hmac's changed underneath the packet parser.
1171 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1173 * If re-key protocol is active then process the incoming packets
1174 synchronously since we must assure that icoming packets encrypted
1175 with the old key is processed before the new keys is set to
1176 use. This is true other packets than for REKEY packets.
1177 Affected file silcd/server.c. The same was done to client library
1178 as well, affected file lib/silcclient/client.c.
1180 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * Fixed bug in client and server to accept the force send if
1183 the packet is send from silc_[server/client]_packet_process
1184 function. Otherwise the packets are never delivered, oops.
1186 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1188 * Disable force sending of packets when REKEY protocol is active.
1189 We must assure that no packet is sent directly when rekey is
1190 performed. All packets must be sent through packet queue.
1191 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1192 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1193 function is silc_[server/client]_packet_send_real to check
1196 * Replaced the SIM paths from example config files to
1197 /usr/local/modules. Also, make install creates now
1198 /usr/local/silc/logs directory to hold all the SILC server
1201 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1203 * Made the configure.in.pre work on Solaris. Patch by salo.
1205 * Made all ciphers compatible with non-x86 machines. Defined
1206 CBC mode macros into lib/silccrypt/ciphers_def.h.
1208 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1210 * Fixed the make install.
1212 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1214 * When MAC computation fails the silc_packet_decrypt returned 0
1215 even though it was supposed to return -1. Fixed this. The
1216 affected file is lib/silccore/silcpacket.c.
1218 * Do not replace the config files in /etc/silc (in make install)
1219 if they already exist. Affected file ./Makefile.am.
1221 * Do not send re-key packets immediately but through packet queue.
1222 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1224 * Changed silc_net_check_host_by_sock to return FALSE if the
1225 IP/DNS could not be resolved. Though, it returns the IP address
1226 now even if it could not resolve it (but returns also FALSE).
1227 Affected file lib/silcutil/silcnet.[ch].
1229 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1231 * Added silc_pkcs_decode_identifier to decode the public key's
1232 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1233 Added also silc_pkcs_free_identifier. Added also new context
1234 SilcPublicKeyIdentifier.
1236 * Added -S option to the silc client. It is used to dump the
1237 contents of the specified public key file.
1239 * Changed the PKCS api to return the public key length when
1240 setting the public key.
1242 * Fixed a fatal bug in the public and private key file loading.
1243 Affected file lib/silccrypt/silcpkcs.c.
1245 * Execute the packet parsing for client with zero (0) timeout
1246 if the protocol is active. Affected file silcd/server.c.
1248 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1250 * Made the key generation options to the silcd program. Added
1251 -C option, equivalent to client's option.
1253 * Added new [ServerKeys] config section to the server. It
1254 configures the server's public and private key.
1256 * Defined generic Public Key Payload into the protocol
1257 specification to send specific type of public keys and
1260 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1261 public key or certificate.
1263 * Implemented the GETKEY command to the server and to the
1264 client library and on user interface.
1266 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1268 * Made preliminary `make install' work.
1270 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1272 * Added SilcServerRekey context into silcd/idlist.h.
1274 * Added the PFS support as defined in the specification to the
1275 SKE protocol. Affected files lib/silcske/*.c.
1277 * Added `ske_group' field to the SilcServerRekey context to hold
1278 the number of the SKE group that is used with PFS in re-key.
1279 Affected file silcd/idlist.h.
1281 * Added PFS re-key support to the server. Affected file is
1284 * Added silc_protocol_cancel to cancel execution of the next
1285 state of the protocol. Affected file is
1286 lib/silccore/silcprotocol.[ch].
1288 * Added the re-key support with and without PFS to the client
1289 library. Re-key is performed once in an hour, by default.
1291 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1292 Added silc_client_rekey_callback and silc_client_rekey_final.
1293 Affected files are lib/silcclient/protocol.[ch] and
1294 lib/silcclient/client.[ch].
1296 * Removed the `hmac_key' and `hmac_key_len' fields from the
1297 SilcClientConnection structure; not needed. Affected file is
1298 lib/silcclient/client.h.
1302 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1304 * Do not ask whether user wants to use the negotiated private key
1305 for private messages, just use it. Affected file is
1306 silc/local_command.c.
1308 * Added `send_enc_key' and `enc_key_len' fields to the
1309 SilcIDListData structure since they are needed in the re-key
1310 phase. Affected file is silcd/idlist.[ch].
1312 * Implemented the simple re-key protocol into the server.
1313 Affected files silcd/server.c and silcd/protocol.[ch]. The
1314 re-key will be performed once in an hour, by default.
1316 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1317 Added silc_server_rekey, silc_server_rekey_callback and
1318 silc_server_rekey_final.
1320 * Removed Tunneled flag from the protocol. Updated the code
1321 and the specifications.
1323 * Adde `pfs' field to the SilcIDListData to indicate whether
1324 the PFS is to be performed in the re-key. Affected file is
1327 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1329 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1330 int64 of at least the xintXX size. If void * is less that 4
1331 bytes uint32 * will be used. Defined bool as boolean.
1333 * Changed _ALL_ unsigned long and unsigned int to uint32,
1334 unsgined short to uint16 in the source tree.
1336 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1337 not handle clients that has entry->data.registered == FALSE.
1338 They are not in the network anymore. Affected file is
1341 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1343 * Implemented the sending of the SERVER_SIGNOFF notify in the
1344 server. Affected file is silcd/server.c.
1346 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1347 Added also silc_notify_payload_encode_args into the
1348 lib/silccore/silcnotify.[ch].
1350 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1351 Affected file silcd/packet_receive.c.
1353 * Implemented the SERVER_SIGNOFF notify handling in the client
1354 library. Affected file lib/silcclient/client_notify.c. Also,
1355 implemnted the printing of the SERVER_SIGNOFF info to the
1356 application. Affected file silc/client_ops.c.
1358 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1359 if the deleting was successful. Affected file silcd/idlist.[ch].
1361 * Added support for public key authentication in the connection
1362 authentication protocol in the client library. Affected file
1363 lib/silcclient/protocol.c.
1365 * Changed the server's silc_idlist_get_clients_by_* interface
1366 to support already allocated array so that new entries may be
1367 added to pre-allocated array. Affected file silcd/idlist.[ch].
1368 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1369 and command replies.
1371 * All command reply functions in the server now calls the
1372 pending command callback even if error occured. This way the
1373 error will be delivered to the client as well. Affected files
1374 silcd/command.c and silcd/command_reply.c.
1376 * Fixed INFO command to return local server's info if no server
1377 was provided. Affected file lib/silcclient/command.c.
1379 * Removed RESTART command for good. Updated the code and the
1382 * Rewrote parts of the task system. It is a bit simpler now.
1383 Removed unsued task priorities. The affected files are
1384 lib/silcutil/silctask.[ch].
1386 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Moved the USERS printing from the library to the application.
1389 Affected files lib/silcclient/command.c and silc/client_ops.c.
1391 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1395 * Added channel key re-key support. The re-key is perfomed
1396 only by the router and is done once in an hour. Added `rekey'
1397 field to the SilcChannelEntry in the server. Affected files
1398 silcd/server.c and silcd/idlist.h.
1400 * Added silc_task_unregister_by_context into the file
1401 lib/silcutil/silctask.[ch].
1403 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1405 * Added SILC_UMODE_GONE mode to indicate when the client is not
1406 present in the SILC network. Added also support to the local
1407 command AWAY that will set this mode. Added support of showing
1408 "xxx is gone" in WHOIS command. The USERS command shows the
1409 gone status as well.
1411 * Fixed setting server and router operator privileges in the
1412 server's UMODE command. Affected file silcd/command.c.
1414 * Merged the SKE KE1 and KE2 payloads into one payload. The
1415 new KE payload is equivalent to the old KE2 payload.
1417 Cleaned up the SKE Start Payload parsing. It now uses the
1418 simple buffer unformatting to do the parsing. A lot faster
1421 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1422 to the SKE that is used to indicate whether both of the SKE
1423 parties should perform authentication. By default only the
1424 responder performs authentication. By setting this flag also
1425 the initiator must do authentication. By default it is unset
1426 since in normal SKE case, client to server connection, only
1427 the responder should do authentication. When doing SKE between
1428 two clients both should perform authentication. Updated the
1429 code and the protocol specs.
1431 * A little fix to IDENTIFY command in the server. Search the
1432 client first by hash not nickname. Affected file is
1435 * Fixed the silc_client_close_connection to support closing
1436 the client to client connections wihtout deleting too much
1437 data. Affected file lib/silcclient/client.c.
1439 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1440 are received if protocol used to be active but is not anymore
1441 the application would crash due to NULL pointer dereference.
1442 Affected files silcd/server.c and lib/silcclient/client.c.
1444 * Added `hash' field to the SilcClientConnection to include
1445 the hash function negotiated in the SKE protocol.
1447 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1448 to set the channel founder authentication data. A client can
1449 claim the founder rights later by providing the authentication
1450 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1451 This way the channel founder can regain the channel founder
1452 privileges even it is left the channel. This works only on
1453 local server and the client must be connected to the same
1454 server to be able to regain the founder rights. Updated the
1455 protocol specs accordingly.
1457 Added support to the CMODE command in the client to set the
1458 founder auth data. Read the README to see how to set it.
1460 Added support to the CUMODE command to claim the founder
1461 rights. Read the README to see how to do it.
1463 Added support for the founder authentication to the Channel
1464 Entry in the server. Affected file silcd/idlist.h.
1466 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1467 server's CMODE command. Affected file silcd/command.c.
1469 * Added the following new functions into lib/silccore/silcauth.[ch]:
1470 silc_auth_get_method and silc_auth_get_data.
1472 * The server now saves the remote hosts public key to the
1473 SilcIDListData pointer. Affected file silcd/protocol.c.
1475 * The normal server now does not remove the channel entry from
1476 the cache if the founder authentication data is set. It used
1477 to remove it if the founder was the last one on the channel on
1478 the server and left the channel. The auth data is saved and
1479 if the channel is re-joined later the old entry is used with
1480 the old auth data. Affected files silcd/command_reply.c and
1483 * Removed the `pkcs' field from the SilcIDListData structure
1484 in the server; it is not used. Affected file silcd/idlist.h.
1486 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1488 * Fixed packet processing on slow links. Partial packets were
1489 never re-processed because the incoming data buffer was cleared
1490 by the application. Application must not directly clear the
1491 sock->inbuf, the packet processing routines handle it. Fixed
1492 this in client library and in server.
1494 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1496 * Fixed the WHOIS and IDENTIFY send reply function to really
1497 check whether to send list or just one entry. Affected file
1500 * Cleaned up the LEAVE command's channel key distribution. The
1501 affected file silcd/command.c.
1503 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1504 can enforce the channel mode as well. In that case the ID
1505 includes the ID of the server. The code now enforces the
1506 mode change if the router have different mode than the server.
1508 * The notify client operation with CMODE_CHANGE notify can now
1509 return NULL client_entry pointer if the CMODE was not changed
1510 by client. Application must check for this.
1512 * Added <Server ID> argument to INFO command to support server
1513 info fetching by Server ID.
1515 * Added silc_server_announce_get_channel_users to get assembled
1516 packets of channel users of the specified channel. Affected
1517 file silcd/server.[ch].
1519 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1520 was freed underneath the ID Cache.
1522 * Re-announce clients when the server received CHANNEL_CHANGE
1523 notify from the router. Affected file silcd/packet_send.c.
1525 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1527 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1528 crashed since it did not handle the fact that there is no cipher
1529 called "3" and didn't check the error condition. Now fixed.
1531 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1532 flag. It can be used to send message requests.
1534 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1536 * Implemented the RESTART command in the client.
1538 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1539 notice type messages. Added notice printing to the user
1542 * The channel keys are not re-generated if the channel's mode
1543 is PRIVKEY, ie private key on the channel exists. Affected
1544 files silcd/server.c and silcd/command.c.
1546 * Fixed a little bug in channel message delivery when channel
1547 private keys are set in the server. Affected file is
1548 silcd/packet_send.c.
1550 * Changed the setting on channel->on_channel = TRUE from the
1551 silc_client_save_channel_key to the JOIN command reply. The
1552 key payload is not received if the private channel key is set.
1553 Affected file lib/silcclient/command_reply.c and the
1554 lib/silcclient/client_channel.c.
1556 * When the CMODE_CHANGE notify is sent and the channel private
1557 key mode is removed the channel key must be re-generated in
1558 other cells as well. Added this support for the router in the
1559 silcd/packet_receive.c.
1561 * Added new local command NOTICE to send notice message on
1562 channel. Affected file silc/local_command.[ch].
1564 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1566 * Added new local command ME to the client. It is used to send
1567 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1568 some action. Affected file silc/local_command.[ch].
1570 * Changed channel_message and private_message client operations
1571 to deliver the message flags to the application. Added also
1572 the `flags' arguments to the silc_client_send_channel_message
1573 and silc_client_send_private_message functions. Affected file
1576 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1578 * Redefined the Private Message Payload to support private message
1579 keys and to support the new private message flags. Updated
1580 the protocol specs. Flags makes it possible to have for example
1581 CTCP style messages.
1583 * Added new type SilcPrivateMessagePayload and defined an API
1584 for it in the lib/silcclient/silcprivate.[ch].
1586 * Tested private message private keys successfully. Tested the
1587 private message key set, unset and list commands with the new
1590 * Redefined the Channel Message Payload to include the channel
1591 message flags (equal with private message flags) to support
1592 for example CTCP style messages.
1594 * Defined some of the message (for channel and private message)
1595 flags. Updated the protocol specs and added the flags to the
1596 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1598 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1600 * Added SilcKeyAgreementStatus type to the key agreement routines
1601 to indicate the current status and error if one occured.
1602 The status types are defined in the lib/silcclient/silcapi.h.
1604 * Added new local command KEY that is used to set and unset private
1605 keys for channels, set and unset private keys for private messages
1606 with remote clients and to send key agreement requests and
1607 negotiate the key agreement protocol with remote client. The
1608 key agreement is supported only to negotiate private message keys,
1609 it currently cannot be used to negotiate private keys for channels,
1610 as it is not convenient for that purpose.
1612 * Fixed a minor pending callback setting bug in the function
1613 silc_client_get_client_by_id_resolve, now the function works.
1614 Affected file lib/silcclient/idlist.c.
1616 * Added function silc_net_get_local_port to get local bound
1617 port by socket. Added to lib/silcutil/silcnet.[ch].
1619 * Added `sockets' and `sockets_count' fields to the SilcClient
1620 object. They hold the sockets of the listenning sockets in
1621 the client. Listenning sockets may be for example the key
1622 agreement server. Affected file lib/silcclient/client.[ch].
1623 Added functions the silc_client_add_socket and the
1624 silc_client_del_socket. They are exported to the application
1627 * Added ~./silc/clientkeys to support other client's public keys.
1629 * Renamed verify_server_key client operation to verify_public_key
1630 and added one argument to indicate the type of the connection
1631 (server, client etc.).
1633 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1635 * Added silc_server_connection_auth_request to handle the
1636 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1637 silcd/packet_receive.[ch].
1639 * Added silc_server_send_connection_auth_request into the
1640 silcd/packet_send.c to send the connection auth request packet.
1642 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1645 * Fixed the public key authentication in responder side in the
1646 server. The `auth_data' pointer includes the SilcPublicKey
1647 not the path to the public key. Affected file silcd/protocol.c.
1649 * Implemented the public key authentication in the initiator side
1650 in the server. Affected file silcd/protocol.c.
1652 * Removed the [RedirectClient] config section from the server
1653 configuration. Is not needed and I don't want to implement it.
1655 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1657 * Cleaned up the CMODE command in the server. It now works
1658 correctly and supports all the modes defined in the protocol.
1659 Affected file is silcd/command.c.
1661 * Added `hmac_name' field to the SilcChannelEntry in the server
1662 to hold the default HMAC of the channel. It can be set when
1663 creating the channel (with JOIN command). Affected files
1666 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1667 type to indicate the change of the current cipher and hmac
1668 on the channel. Client can safely ignore the <cipher> argument
1669 (if it chooses to do so) since the CHANNEL_KEY packet will
1670 force the channel key change anyway. The <hmac> argument is
1671 important since the client is responsible of setting the new
1672 HMAC and the hmac key into use.
1674 * Fixed the CMODE command in the client library as well.
1676 * Tested CMODE command in router environment successfully.
1678 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1680 * Show the version of the remote client (or server) when connecting
1681 to the server. It is logged to the log file. Affected file
1682 is silcd/protocol.c.
1684 * Fixed the KILLED notify handling in the client library. The
1685 client must be removed from all channels when receiving the
1688 Also, do not remove the client entry when giving the KILL
1689 command but when the KILLED notify is received.
1691 * Removed silc_idlist_find_client_by_nickname from the server.
1692 Not needed anymore. Affected files silcd/idlist.[ch].
1694 * Implemented the CHANNEL_CHANGE notify type handling to the
1695 server. Affected file silcd/server.c.
1699 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1701 * Added silc_server_send_notify_invite to send the INVITE
1702 notify between routers.
1704 * Implemented the INVITE command correctly to the server.
1706 * Implemented the INVITE notify type handling in the server.
1708 * Implemented the INVITE command to the client library and on the
1711 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1713 * Added function silc_server_get_client_resolve to find the
1714 client entry by ID from all ID lists and then resolve it
1715 (using WHOIS) if it cannot be found. Affected file is
1718 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1720 * Implemented the BAN command to the client library.
1722 * The JOIN command in the server now checks the invite list
1725 * Changed the silc_command_reply_payload_encode_va and the
1726 silc_command_payload_encode_va to support that if argument is
1727 NULL it ignores and checks the next argument. Affected file
1728 lib/silccore/silccommand.c.
1730 * Added silc_server_send_notify_ban to send the BAN notify
1731 type between routers.
1733 * Chaned the silc_notify_payload_encode to support that if
1734 argument is NULL it ignores and checks the next argument.
1735 Affected file lib/silccore/silcnotify.c.
1737 * Tested ban lists in router environment successfully.
1739 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1741 * Implemented BAN command to the server, in silcd/command.[ch].
1743 * Removed the BAN and INVITE_LIST modes from the CMODE command
1746 * Added function silc_string_match to regex match two strings.
1747 Affected files lib/silcutil/silcutil.[ch].
1749 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1751 * Redefined parts of the SilcChannelEntry in the server to support
1752 the new ban and invite lists.
1754 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1756 * Redefined the INVITE command. The same command can be used to
1757 invite individuals to the channel but also to manage the invite
1758 list of the channel (to add to and remove from the invite list).
1759 Updated the protocol specs.
1761 * Added new command SILC_COMMAND_BAN that can be used to manage
1762 the ban list of the channel. Updated the protocol specs.
1764 * Removed the channel modes: the SILC_CMODE_BAN and the
1765 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1766 in the CMODE command. The equivalent features are now available
1767 using INVITE and BAN commands. Updated the protocol specs.
1769 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1770 in the network about change in the current ban list. The notify
1771 type is not used by the client.
1773 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1774 support the invite lists.
1776 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1778 * Added new function silc_string_regexify that converts string
1779 including wildcard characters into regex string that can
1780 be used by the GNU regex library. Added into the file
1781 lib/silcutil/silcutil.[ch].
1783 Added silc_string_regex_combine to combine to regex strings
1784 into one so that they can be used as one regex string by
1785 the GNU regex library. Added into the file
1786 lib/silcutil/silcutil.[ch].
1788 Added silc_string_regex_match to match two strings. It returns
1789 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1791 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Imported GNU regex to the soruce tree into lib/contrib.
1794 Fixed some compiler warning from the regex.c.
1796 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * Fixed MOTD command in the server to work in router environment.
1800 * Fixed the MOTD command in the client library to support
1801 the server argument in the command.
1803 * Added `nickname_len' argument to the silc_idlist_add_client
1804 in the server, as the `nickname' argument may be binary data
1807 * Added silc_idlist_get_channels to return all channels from
1810 * Implemented LIST command to the server. Affected file is
1813 * Implemented the LIST command to the client library and on the
1816 * Added [<user count>] argument to the LIST command reply.
1817 With private channels the user count is not shown.
1819 * Updated TODO and README.
1821 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1823 * The client entry's data.registered must be TRUE even with
1824 global client entry on global client list. The data.registered
1825 is used to check whether the client is anymore in the network,
1826 for example with WHOWAS command so it must be valid.
1828 * Fixed the WHOWAS command in the server. It now actually works
1829 in router environment. Added function into silcd/command_reply.c
1830 silc_server_command_reply_whowas_save.
1832 * Added silc_idlist_purge function to the silcd/idlist.c
1833 to periodically purge the ID Cache.
1835 * Fixed INFO command in the server. It works now in router
1836 environment. Added <server name> argument to the INFO command
1837 reply. Updated the protocol specs.
1839 * Fixed minor bug in silc_idcache_purge to not purge if the
1840 expire value is zero.
1842 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1843 they were buggy because of the WHOWAS information.
1845 * Fixed local command MSG to handle the async resolving of
1846 the remote client properly. It used to fail the first MSG.
1847 Affected file silc/local_command.c.
1849 * Added `data_len' field to SilcIDCache context.
1851 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1853 * Update TODO. Todo in commands in the server.
1855 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1857 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1858 used by routers as broadcast packet to inform other routers
1859 about the changed user mode.
1861 Implemented the notify handling in the server. Affected file is
1862 silcd/packet_receive.c. Added the function
1863 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1865 * Added new generic Channel Payload and deprecated the New Channel
1866 Payload. The New Channel Payload is now the generic Channel
1869 * Added new argument `mode' to the silc_server_send_new_channel
1870 as it is required in the Channel Payload now.
1872 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1873 and created a new and real SilChannelPayload to represent the
1874 new generic Channel Payload. Implemented the encode/decode
1875 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1877 * Added silc_server_get_client_channel_list to return the list
1878 of channels the client has joined for WHOIS command reply.
1879 Affected file silcd/server.[ch].
1881 * Implemented the channel list sending in the WHOIS command reply
1882 in server and in the client.
1884 Implemented the channel list displaying on the user interface
1885 as well. Affected file silc/client_ops.c.
1887 * Added silc_channel_payload_parse_list to parse list of Channel
1888 Payloads. It returns SilcDList list of SilcChannelPayloads.
1889 Client for example can use this function to parse the list of
1890 channels it receives in the WHOIS command reply. The caller
1891 must free the list by calling silc_channel_payload_list_free.
1892 Affected files lib/silccore/silcchannel.[ch].
1894 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1896 * Added one new argument <user mode> to the WHOIS command reply
1897 to return the mode of the user in SILC. Updated the protocol
1900 Implemented it to the server and client.
1902 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1904 * Fixed the mode printing on the user interface on joining.
1905 Affected file silc/client_ops.c.
1907 * Implemented the UMODE command and user modes in general to the
1908 client library and to the user interface.
1910 * Implemented the UMODE command to the server.
1912 * The server now sends UNKNOWN_COMMAND error status if client sends
1913 unknown command. Affected file silcd/command.c.
1915 * All server commands now handle the command identifier the right
1916 way when sending the command reply to the client. The client can
1917 use to identify the command replies with the identifier.
1919 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1921 * Added silc_server_get_client_route to resolve the route to
1922 the client indicated by the client ID. Affected file is
1925 * Added silc_server_relay_packet as general function to relay
1926 packet to arbitrary destination. This deprecates functions
1927 like _send_private_message_key, _relay_notify etc. Affected
1928 file is silcd/packet_send.[ch].
1930 Removed silc_server_send_key_agreement,
1931 silc_server_send_private_message_key and
1932 silc_server_packet_relay_notify functions from the file
1933 silcd/packet_send.[ch].
1937 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1938 server. Affected file silcd/packet_receive.[ch].
1940 * Implemented the KILL command to the client. Implemented the
1941 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1942 Affected files lib/silcclient/command[_reply].c and
1943 lib/silcclient/client_notify.c. Implemented the KILL notify
1944 printing in the user inteface.
1946 * Fixed a lot silc_parse_nick memory leaks from the client
1947 library in the file lib/silcclient/command.c.
1949 * Changed the silc_server_send_notify_on_channels's `sender'
1950 argument from SilcSocketConnection to SilcClientEntry to
1951 check the sender as entry and not as connection object and not
1952 to send to the client provided as argument. The affected file
1953 is silcd/packet_send.[ch].
1955 * The notify packets that are destined directly to the client used
1956 to not to be processed by the server. Now changed that and the
1957 server processes all notify packets. After relaying the packet
1958 to the client the notify packet is processed in the server.
1960 * The silc_server_free_client_data now checks whether there is
1961 pending outgoing traffic for the client and purges the data to
1962 the network before removing the client entry.
1964 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1966 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1967 an client is killed from the SILC Network. Updated the protocol
1970 Added new function silc_server_send_notify_killed to the
1971 silcd/packet_send.[ch].
1973 * Added function silc_server_packet_relay_notify to relay notify
1974 packets that are destined directly to a client. In this case
1975 the server does not process the notify packets but merely relays
1976 it to the client. Affected file silcd/packet_send.[ch].
1978 Added also silc_server_packet_process_relay_notify to check
1979 whereto relay the notify. Affected file is
1980 silcd/packet_receive.[ch].
1982 * Implemented the KILL command to the server.
1986 * Added the backup schema desgined last fall to the protocol
1987 specs for everyone to see. The specification is in the
1988 *-spec-xx.txt draft and the packet type definitions for the
1989 backup routers is in *-pp-xx.txt draft. Thusly, added also
1990 new packet type SILC_PACKET_CELL_ROUTERS.
1992 * A big security problem in the implementation discovered. The
1993 signoff of an client did not cause new channel key generation
1994 which it of course should've done. The channel keys must be
1995 always re-generated when client leaves (or signoffs) the channel.
1996 The silc_server_remove_from_channels funtion now handles
1997 the channel key re-generation.
1999 * Added `sender' argument to the silc_server_send_notify_on_channels
2000 to not to send the client provided as argument. Affected file
2001 silcd/packet_send.[ch].
2003 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2005 * Implemented OPER and SILCOPER commands into the server and
2008 * Added silc_auth_verify and silc_auth_verify_data to verify
2009 the authentication directly from the authentication payload.
2010 It supports verifying both passphrase and public key based
2011 authentication. Affected file lib/silccore/silcauth.[ch].
2013 * Added `hash' field to the SilcIDListData structure. It is the
2014 hash negotiated in the SKE protocol. Affected file is
2017 * Slight redesigning of the SilcAuthPayload handling routines.
2018 Do not send SilcPKCS but SilcPublicKey as argument.
2020 * Implemented the public key authentication support to the
2021 serverconfig. The public key is loaded from the provided path
2022 and saved as authentication data to void * pointer. Thus,
2023 changed the unsigned char *auth_data to void *auth_data;
2025 * Fixed SHUTDOWN command to send the reply before the server
2026 is shutdown. :) Affected file silcd/command.c.
2028 * Fixed fatal bug in CONNECT command. The hostname was invalid
2029 memory and server crashed. Affected file silcd/command.c.
2031 * Fixed fatal bug in CLOSE command. The server_entry became
2032 invalid but was referenced later in the command. Affected file
2035 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2037 * Fixed fatal bug in failure packet handling. Server ignored
2038 the failure and thus crashed when it came.
2042 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2044 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2045 that the command may be executed only once in (about) 2 seconds.
2046 The old SILC_CF_LAG flag is same but allows command bursts up
2047 to five before limiting.
2049 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2050 server code. Various commands now includes the CF_LAG_STRICT
2051 flag to disallow any kind of miss-use of the command.
2053 * Fixed the silc_buffer_unformat to not to allocate any data
2054 if the length of the data is zero. It used to allocate the
2055 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2057 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2059 * Changed the format of AdminConnection configuration section
2060 in the server. Added username of the admin to the format.
2061 Affected files silcd/serverconfig.[ch].
2063 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2064 to return admin configuration data by host, username and/or
2067 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2069 * Implemented WHOWAS command to the server. Added the functions:
2071 silc_server_command_whowas_parse,
2072 silc_server_command_whowas_send_reply,
2073 silc_server_command_whowas_from_client and
2074 silc_server_command_whowas_from_server
2076 * Added <Client ID> argument to the WHOWAS command reply. Updated
2077 the protocol specs accordingly.
2079 * Implemented WHOWAS command and command_reply to the client
2082 Implemented the WHOWAS printing on the user interface.
2084 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2086 * Added new argument to the WHOWAS command reply, the real name.
2087 It is an optional argument. Updated the protocol specs.
2089 * Added SilcIDCacheDestructor callback that is registered when
2090 the SilcIDCache is allocated. The callback is called when
2091 an cache entry in the ID Cache expires, or is purged from the
2092 cache. Added into lib/silccore/idcache.[ch].
2094 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2095 to destruct the client entries when the cache entry expires.
2096 Other ID Cache's in server and in the client library ignores
2099 * If the ID Cache entry's `expire' field is zero then the entry
2100 never expires. Added boolean `expire' argument to the
2101 silc_idcache_add function in the lib/silccore/idcache.[ch].
2102 If it is TRUE the default expiry value is used.
2104 * Added silc_server_free_client_data_timeout that is registered
2105 when client disconnects. By default for 5 minutes we preserve
2106 the client entry for history - for WHOWAS command.
2108 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2110 * Added support to the server to enforce that commands are not
2111 executed more than once in 2 seconds. If server receives
2112 commands from client more frequently, timeout is registered
2113 to process the commands. Affected file silcd/command.c.
2114 Added new function silc_server_command_process_timeout.
2116 * Changed NICK_NOTIFY handling in client library to check that
2117 if the client's nickname was changed, so there is no need to
2118 resolve anything from the server.
2120 * Removed error printing from the WHOIS and IDENTIFY commands.
2121 If error occurs then it is ignored silently in the client library.
2122 The application, however, may map the received error to
2123 human readable error string. The application currently maps
2124 the NO_SUCH_NICKNAME error to string.
2126 * Made the command status message public to the application. Moved
2127 them from lib/silcclient/command_reply.c to
2128 lib/silcclient/command_reply.h. The application can map the
2129 received command status to the string with the
2130 silc_client_command_status_message function.
2132 * Added check to the server to check that client's ID is same
2133 as the Source ID in the packet the client sent. They must
2136 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2138 * Added dist-bzip hook to the Makefile.am to make bzip2
2139 compressed distributions.
2141 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2143 * Server now enforces the maximum length for the nickname and
2144 the channel as protocol specification dictates. 128 bytes for
2145 nickname and 256 bytes for channel name.
2147 * Moved the WHOIS printing to the application. The client libary
2148 does not print out the WHOIS information anymore, the application
2149 must do it. Renamed silc_client_command_reply_whois_print to
2150 the silc_client_command_reply_whois_save.
2152 The client's idle time is also sent to the application now, and
2153 the idle is shown on screen.
2155 * Added silc_client_command_reply_identify_save to save the
2156 received IDENTIFY entries.
2158 * Do not check for channel private keys in message sending and
2159 reception if the channel does not have the PRIVKEY mode set.
2160 Affected file lib/silclient/client_channel.c.
2162 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2164 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2165 just surfaced after chaning the JOIN procedure.
2167 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2169 * Added silc_client_get_clients_by_list to get client entries
2170 from Client ID list, that is returned for example by JOIN
2171 and USERS command replies. The application should use this
2172 function for example when JOIN command reply is received to
2173 resolve the clients already on the channel (library does not
2174 do that anymore as USERS command reply is not used in the JOIN
2175 procedure anymore). Affected files lib/silcclient/silcapi.h and
2176 lib/silcclient/idlist.c.
2178 * JOIN command reply and USERS command reply returns now SilcBuffer
2179 pointers instead of unsigned char pointers when returning
2180 the client list and mode list.
2182 * Added <Client ID> argument to the JOIN command reply, mainly
2183 for the server to identify for which client the command was
2184 originally sent. Updated protocol specs accordingly.
2186 * Added SilcDlist private_key pointer to the SilcChannelEntry
2187 in the client to support the channel private keys. Affected
2188 file is lib/silcclient/idlist.h.
2190 * Added SilcChannelPrivateKey argument to the function
2191 silc_client_send_channel_message so that application can choose
2192 to use specific private ke if it wants to. If it is not provided,
2193 the normal channel key is used, unless private keys are set.
2194 In this case the first (key that was added first) is used
2195 as the encryption key.
2197 * Implemented the support for channel private key handling.
2198 Implemented the following functions:
2200 silc_client_add_channel_private_key,
2201 silc_client_del_channel_private_keys,
2202 silc_client_del_channel_private_key,
2203 silc_client_list_channel_private_keys and
2204 silc_client_free_channel_private_keys
2206 Affected file lib/silcclient/client_channel.c.
2208 * Added the support for the private keys in the channel message
2209 sending and encryption and in the message reception and
2210 decryption. Affected funtions are
2211 silc_client_send_channel_message and silc_client_channel_message.
2213 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2215 * Added SKE's key verify callback to the client library's
2216 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2218 * Removed the statement that server (or router) must send USERS
2219 command reply when joining to the channel so that the client
2220 knows who are on the channel. Instead, the client list and
2221 client's mode list is now sent in the JOIN command reply to the
2222 client who joined channel. This is better solution.
2224 * Added function silc_server_get_users_on_channel and function
2225 silc_server_save_users_on_channel to the silcd/server.[ch].
2227 * Removed function silc_server_command_send_users from the
2230 * Do not show topic on the client library anymore. The topic is
2231 sent in the command reply notify to the application and the
2232 application must show the topic now.
2234 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2236 * Added client searching by nickname hash into the IDENTIFY and
2237 WHOIS commands in the server as they were clearly missing from
2238 them. Affected file is silcd/command.c.
2240 * Fixed a bug in private message receiving in the client library.
2241 The remote ID was freed and it wasn't supposed, now it is
2244 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2246 * Minor fix to the channel payload; allocate the data area, as it
2247 needs to be of specific length.
2249 * If the key agreement port is zero then the operating
2250 system will define the bound port. Affected files are
2251 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2253 * Added new function silc_channel_payload_decrypt into the file
2254 lib/silccore/silcchannel.[ch].
2256 * Moved the channel message etc, check from silc_packet_decrypt
2257 to applications. The library calls now a generic
2258 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2259 when the packet is either normal or special. This was done to
2260 allow more wide range of checking that was not allowed when
2261 the code was in library. Now applications can do virtually any
2262 checks to the packet and return to the library the decision how
2263 the packet should be processed. Affected files are
2264 lib/silccore/silcpacket.[ch].
2266 Added silc_server_packet_decrypt_check to the server and
2267 silc_client_packet_decrypt_check to the client library.
2269 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2270 to send with specified source and destination information.
2272 * Channel message delivery between routers was broken after the
2273 channel key distribution was fixed earlier. The channel key
2274 was used be to distributed to other routers as well which is not
2275 allowed by the protocol. Now this is fixed and channel keys
2276 really are cell specific and the channel message delivery between
2277 routers comply with the protocol specification.
2279 * Fixed various commands in server to check also the global list
2280 for the channel entry and not just the local list. The affected
2281 file silcd/command.c.
2283 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2285 * Added assert()s to buffer formatting and unformatting routines
2286 to assert (if --enable-debug) when error occurs. Affected
2287 file: lib/silcutil/silcbuffmt.c.
2289 * Changed to auto-reconnect to check whether the remote host is
2290 router and register the re-connect timeout if it is. It used
2291 to check that whether we are normal server, but router must do
2292 auto-reconnect with another router as well. Affected file
2295 * Removed the [<key len>] option from CMODE command as the cipher
2296 name decides the key length, nowadays. See the defined ciphers
2297 from the protocol specification.
2299 * Added [<hmac>] option to the CMODE command to define the HMAC
2300 for the channel. Added SILC_CMODE_HMAC channel mode.
2302 * Added [<hmac>] option for the JOIN command so that user can
2303 select which HMAC is used to compute the MACs of the channel
2306 * Added Hmac field to the Channel Message Payload. The integrity
2307 of plaintext channel messages are now protected by computing
2308 MAC of the message and attaching the MAC to the payload. The
2309 MAC is encrypted. Now, it is clear that this causes some
2310 overhead to the size of the packet but rationale for this is that
2311 now the receiver can verify whether the channel message decrypted
2312 correctly and also when private keys are set for the channel the
2313 receiver can decrypt the packet with several keys and check from
2314 the MAC which key decrypted the message correctly.
2316 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2317 lib/silccrypt/silccipher.[ch].
2319 * Added silc_hash_len to return the digest length into the
2320 lib/silcrypt/silchash.[ch].
2322 * Rewrote parts of Silc Channel Payload interface in the
2323 lib/silccore/silcchannel.[ch]. The encode function now also
2324 encrypts the packet and parse function decrypts it.
2326 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2328 * Fixed a minor formatting bug in the SKE's key material processing.
2329 It actually might have processed the keys wrong way resulting
2332 * Redefined the mandatory HMAC algorithms and added new algorithms.
2333 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2334 and hmac-md5 truncated to 96 bits. The mandatory is now
2335 hmac-sha1-96. Rest are optional (including the one that used
2336 to be mandatory). Rationale for this is that the truncated HMAC
2337 length is sufficient from security point of view and can actually
2338 make the attack against the HMAC harder. Also, the truncated
2339 HMAC causes less overhead to the packets. See the RFC2104 for
2342 * Added new [hmac] configuration section. The SKE used to use
2343 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2344 is of course wrong. The official names that must be proposed in
2345 the SKE are the ones defined in the protocol specification
2346 (hmac-sha1-96 for example). The user can configure any hmac
2347 using any hash function configured in the [hash] section. At
2348 least, the mandatory must be configured.
2350 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2352 * Added HMAC list to the SKE proposal list. It has now both
2353 hash algorithm list and HMAC list. This makes the protocol
2354 incompatible with previous versions. The SKE now seems to work
2355 the way it is supposed to work, for the first time actually.
2357 * Defined plain Hash algorithms to the protocol specification.
2360 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2362 * Implemented support for key agreement packets into the server.
2363 Added functions silc_server_key_agreement and
2364 silc_server_send_key_agreement. Other than these functions,
2365 server has nothing to do with this packet.
2367 * Added support for private message key packets into the server.
2368 Added functions silc_server_private_message_key and
2369 silc_server_send_private_message_key.
2373 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2374 called in the protocol's final callback instead in the END
2375 protocol state. This makes a little more sense and in the same
2376 time in client we can use the same protocol routines for normal
2377 key exchange and to key agreement packet handling as well.
2379 * Added to both client's and server's KE protocol context the
2380 SilcSKEKeyMaterial pointer to save the key material. We will
2381 bring the key material to the protocol's final callback by doing
2382 this. The final callback must free the key material.
2384 * Added SKE's packet_send callback into client's KE protocol
2385 context so that the caller can choose what packet sending function
2386 is used. This way we can use different packet sending when
2387 doing normal SKE when doing key agreement packet handling (in
2388 the key agreement packet handling we do not want to encrypt
2391 * Implemented the responder side of the key agreement routines
2392 in the client. The client can now bind to specified port and
2393 accept incoming key negotiation. The key material is passed
2394 to the application after the protocol is over.
2396 * Implemented the processing of incoming Key Agreement packet
2397 in the client. Added function silc_client_key_agreement to
2400 * Implemented the intiator side of the key agreement routines
2401 in the client. The client can now initiate key agreement with
2402 another remote client. The key material is passed to the
2403 application after the protocol is over.
2405 * Created client_keyagr.c to include all the key agreement
2408 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2409 SILC_TASK_CALLBACK except that it is not static.
2411 * Created client_notify.c and moved the Notify packet handling
2412 from the client.[ch] into that file.
2414 * Created client_prvmsg.c and moved all private message and
2415 private message key routines from the client.[ch] into that file.
2417 * Create client_channel.c and moved all channel message and
2418 channel private key routines from the client.[ch] into that file.
2420 * Changed silc_client_get_client_by_id_resolve to resolve with
2421 WHOIS command instead of IDENTIFY command, in the file
2422 lib/silclient/idlist.c.
2424 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2426 * Implemented the SKE's responder side to the Client library.
2428 * When FAILURE is received to the protocol do not trust it
2429 blindly. Register a timeout to wait whether the remote closes
2430 the connection as it should do it, only after that process the
2431 actual failure. This was changed to both client and server.
2433 * Added client_internal.h to include some of the structures
2434 there instead of client.h in lib/silcclient/.
2436 * Added function silc_task_unregister_by_callback to unregister
2437 timeouts by the callback function.
2439 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2441 * Some "Incomplete WHOIS info" errors has been appearing on the
2442 log files. Took away the entry->userinfo check from WHOIS
2443 reply sending. The entry->userinfo is now " " if client did not
2444 provide one. I thought this was fixed earlier but something
2445 is wrong still. Let's see if the error still appears.
2447 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2449 * Fixed a minor bug in the login when the channel key is
2450 re-generated in the server. It used to generate the key in
2451 wrong order and thus caused problems in the channel traffic.
2453 * Fixed a minor bug in channel key distsribution after
2454 KICK command. The key was not sent to the router even though
2457 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2459 * Added silc_ske_process_key_material_data as generic routine
2460 to process any key material as the SILC protocol dictates. The
2461 function is used by the actual SKE library but can be used by
2462 applications as well. This relates to the private message keys
2463 and the channel private keys since they must be processed the
2464 same way the normal SILC session keys. The protocol dictates
2465 this. Affected files: lib/silcske/silcske.[ch].
2467 Added also silc_ske_free_key_material to free the
2468 SilcSKEKeyMaterial structure.
2470 * Defined silc_cipher_set_key function to set the key for
2471 cipher without using the object's method function. The affected
2472 files: lib/silccrypt/silccipher.[ch].
2474 * Implemented silc silc_client_add_private_message_key,
2475 silc_client_add_private_message_key_ske,
2476 silc_client_del_private_message_key,
2477 silc_client_list_private_message_keys and
2478 silc_client_free_private_message_keys functions in the
2481 Added functions silc_client_send_private_message_key to send
2482 the Private Message Key payload and silc_client_private_message_key
2483 to handle incoming Private Message Key payload.
2485 * Added Cipher field to the Private Message Key payload to set
2486 the cipher to be used. If ignored, the default cipher defined
2487 in the SILC protocol (aes-256-cbc) is used.
2489 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2491 * Removed lib/silcclient/ops.h file.
2493 Redefined parts of the SILC Client Library API. Created new
2494 file silcapi.h that deprecates the ops.h file and defines the
2495 published Client Library API. Defined also private message key
2496 API and channel private key API into the file.
2498 This is the file that the application must include from the
2499 SILC Client Library. Other files need not be included by
2500 the application anymore.
2502 * Added new key_agreement client operation callback and also
2503 defined the Key Agreement library API for the application.
2505 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2507 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2508 is used by clients to request key negotiation between another
2509 client in the SILC network. If the negotiation is started it
2510 is performed using the SKE protocol. The result of the
2511 negotiation, the secret key material, can be used for example
2512 as private message key.
2514 Implemented the Key Agreement payload into the files
2515 lib/silccore/silauth.[ch].
2517 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2519 * Redefined ciphers for the SILC protocol. Added some new ciphers
2520 and defined the key lengths for the algorithms. Changed the
2521 code accordingly. The default key length is now 256 bits.
2523 * Fixed SKE key distribution function silc_ske_process_key_material
2524 when the key length is more than 128 bits. The default key
2525 length in SILC is now 256 bits.
2527 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2528 to indicate unsupported algorithm.
2530 * Renamed rijndael.c to aes.c and all functions as well.
2532 * Fixed a long standing channel key setting bug in client library.
2533 Weird that it has never surfaced before.
2535 * Fixed bug in channel deletion. If the entire channel is removed
2536 then it must also delete the references of the channel entry
2537 from the client's channel list as the client's channel entry and
2538 the channel's client entry share same memory.
2540 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2542 * Implemented CONNECT and SHUTDOWN commands in the client.
2544 * Implemented CLOSE command to the client.
2546 * Added the function silc_idlist_find_server_by_name into the
2547 files silcd/idlist.[ch].
2549 Added the function silc_idlist_find_server_by_conn into the
2550 files silcd/idlist.[ch].
2552 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2554 * DIE command was renamed to SHUTDOWN. Updated the both code
2557 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2558 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2560 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2563 * Added function silc_server_create_connection function to create
2564 connection to remote router. My server implementation actually
2565 does not allow router to connect to normal server (it expects
2566 that normal server always initiates the connection to the router)
2567 so the CONNECT command is only good for connecting to another
2570 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2572 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2573 or some other client was kicked from the channel.
2575 Implemented the handling of the notify type to both client
2578 Implemented silc_server_send_notify_kicked to send the KICKED
2579 notify. It is used to send it to the server's primary router.
2581 * Implemented the KICK command into server and client.
2583 * Added `query' argument to the silc_idlist_get_client function
2584 to indicate whether to query the client from server or not if
2587 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2588 to indicate that the client is not channel founder.
2592 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2594 * Removed the rng context from SilcPacketContext structure and
2595 changed that the packet routine uses the Global RNG API.
2597 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2599 * Added support for quit message that client can "leave" on the
2600 channel when it quits the SILC. It is ditributed inside the
2601 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2603 Added silc_server_free_client_data that will take the
2604 signoff message as argument.
2606 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2608 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2610 * Updated parts of the protocol specification to keep it up
2613 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2615 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2616 payloads in one packet.
2618 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2619 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2620 use now the new List flag.
2622 * Also deprecated the following packet types: REPLACE_ID,
2623 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2625 * Added list support for Notify packet in server.
2627 * Added silc_server_send_notify_channel_change to send the
2628 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2629 the silc_server_send_replace_id.
2631 * Added silc_server_send_notify_nick_change to send the
2632 NICK_CHANGE notify type. Deprecates the function
2633 silc_server_send_replace_id.
2635 * Added silc_server_send_notify_join to send the JOIN notify type.
2636 Deprecates the function silc_server_send_new_channel_user.
2638 * Added silc_server_send_notify_leave to send LEAVE notify type.
2639 Deprecates the function silc_server_send_remove_channel_user.
2641 * Added silc_server_send_notify_cmode and
2642 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2643 types. Deprecates the silc_server_send_set_mode function.
2645 * Added SERVER_SIGNOFF notify type to indicate that server has
2646 quit. This means that all clients on the channel from that
2647 server will drop. This can be also used when netsplit happens.
2649 Deprecated REMOVE_ID packet type since it is not needed anymore
2652 Added silc_server_send_notify_server_signoff to send the
2653 SERVER_SIGNOFF notify type. Deprecates the function
2654 silc_server_send_remove_id.
2656 Added also silc_server_send_notify_signoff to send the
2657 SIGNOFF notify type.
2659 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2660 SILC protocol from this day on. Changed the protocol
2661 specification as well.
2663 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2664 notify type. It is used between routers to notify about
2665 topic changes on a channel.
2667 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2670 * Partly updated the protocol specification to comply with the
2671 changes now made. It is still though a bit outdated.
2673 * The JOIN notify type now takes one extra argument <Channel ID>.
2674 The packet used to be destined to the channel but now the
2675 JOIN type may be sent as list thus it is impossible to
2676 destine it to any specific channel. By adding this argument
2677 it is again possible.
2679 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * Added CREDITS file. The CHANGES and CREDITS file will appear
2682 in the distribution as well.
2684 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2686 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2687 types in the server's silcd/packet_receive.c.
2689 * Implemented CMODE and CUMODE to work in router environment.
2691 * Fixed minor encoding and decoding buglet from the
2692 lib/silccore/silcmode.c.
2694 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2697 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2699 * Changed all SilcConfigServer* and silc_config_server* to
2700 SilcServerConfig* and silc_server_config*, respectively.
2703 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2705 * Associated the ID (client or server ID) to the Authentication
2706 Payload to avoid any possibility of forging. Updated the
2707 protocol specification and the code accordingly.
2709 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2711 * The RSA key length is now save to the RsaKey context in the
2712 key generation process in lib/silccrypt/rsa.c. The key length
2713 is now used to figure out the maximum size of the block allowed
2714 to be encrypted/signed.
2716 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2717 is equivalent to the silc_mp_mp2bin but does not allocate any
2720 * Changed silc_mp_mp2bin API to take length argument. If it is
2721 non-zero then the buffer is allocated that large. If zero, then
2722 the size is approximated using silc_mp_sizeinbase, which however
2725 * Created Global RNG API which is global RNG that application can
2726 initialize. After initializing, any routine anywhere in the
2727 code (including library) can use RNG without allocating a new
2728 RNG object. This was done to allow this sort of use of the
2729 RNG in code that has no chance to allocate RNG object. All
2730 applications currently allocate this and many routines in the
2731 library use this. Affected file lib/silccrypt/silcrng.[ch].
2733 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2734 it to use the Global RNG API.
2736 * Defined Authentication Payload into protocol specification that
2737 is used during SILC session to authenticate entities. It is
2738 used for example by client to authenticate itself to the server
2739 to obtain server operator privileges.
2741 Implemented this payload into the lib/silccore/silcauth.[ch].
2742 Implemented also routines for public key based authentication
2743 as the new protocol specification dictates.
2745 Moved definitions of different authentication methods from
2746 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2748 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2749 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2750 silc_pkcs_verify_with_hash functions into the file
2751 lib/silccrypt/silcpkcs.[ch].
2753 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2755 * The client entry's userinfo pointer must be always valid.
2756 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2757 will fail since it requires the userinfo. Now, the userinfo
2758 is allocated as "" if actual userinfo does not exist. Actually,
2759 it must exist and it is totally Ok to drop client connections
2760 that does not announce the userinfo. However, we will make
2761 this workaround for now.
2763 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2764 to return the remote port by socket.
2766 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2768 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2769 SILC_SERVER_PENDING_EXEC and added an new macro
2770 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2771 data or when error occurs while processing the pending command.
2773 Added new argument `destructor' into silc_server_command_pending
2774 and to the SilcServerCommandPending object. This destructor is
2775 now called after calling the pending callback or if error occurs
2776 immediately. If error occurs the actual pending callback won't
2777 be called at all - only the destructor. The destructor may be
2778 NULL if destructor is not needed.
2780 All this applies for client library code as well. Similar
2781 changes were made there as well for the pending commands.
2783 In the client, the application must now allocate the
2784 SilcClientCommandContext with the silc_client_command_alloc
2787 * Added reference counter to the SilcServerCommandContext. Added
2788 function silc_server_command_alloc and silc_server_command_dup
2791 Same type of functions added to the client library for the same
2794 * Removed the cmd_ident from IDListData away since it is now
2795 global for all connections. It is the command identifier used
2796 in command sending and with pending commands. The affected file
2799 * Added reference counter to the SilcSocketConnection objecet to
2800 indicate the usage count of the object. The object won't be
2801 freed untill the reference counter hits zero. Currently only
2802 server uses this, and client ignores it. The client must be
2803 set to use this too later. The affected files are
2804 lib/silccore/silcsockconn.[ch]. Added also the function
2805 silc_socket_dup to increase the reference counter.
2807 This was mainly added because it is possible that the socket
2808 is removed underneath of pending command or other async
2809 operation. Now it won't be free'd and proper DISCONNECTING
2810 flags, etc. can be set to avoid sending data to connection that
2811 is not valid anymore.
2813 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2814 the connection. After that it sets SILC_SET_DISCONNECTED.
2815 It is, however, possible that the socket data is not still freed.
2816 The silc_server_packet_process now checks that data is not
2817 read or written to connection that is DISCONNECTED. The socket
2818 get's freed when the reference counter hits zero.
2820 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2822 * Changed the client operation API: channel_message operation's
2823 `sender' is now the client entry of the sender, not the nickname
2824 and the `channel' is the channel entry, not the channel name.
2826 In the private_message operation the `sender' is now also the
2827 client entry of the sender not the nickname.
2829 Affected file is lib/silcclient/ops.h and all applications
2830 using the client operations.
2832 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2834 * Moved the calling of ops->connect() from connect_to_server_final
2835 into receive_new_id functin since that is the point when the
2836 client is actually allowed to send traffic to network. The
2837 affected file is lib/silcclient/client.c.
2839 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2841 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2842 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2843 (if needs broadcasting) instead of broadcasting the packets one
2844 by one which would make a burst in the network traffic.
2846 * Added `broadcast' argument to the functions in silcd/server.[ch]
2847 silc_server_create_new_channel[_with_id] to indicate whether
2848 to send New Channel packet to primary router.
2850 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2852 * Added new function into the silcd/server.[ch] files:
2853 silc_server_create_new_channel_with_id to create new channel with
2854 already existing Channel ID.
2856 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2857 lib/silccore/silcpacket.h. This packet is used t send list of
2858 Set Mode payloads inside one packet. Server uses this to set
2859 the modes for the channels and clients on those channels, that it
2860 announced to the router when it connected to it. The protocol
2861 specification has been updated accordingly.
2863 * The silc_server_new_channel did not handle the packet coming
2864 from normal server as it normally does not send that. However,
2865 when it announces its channels it does send it. Implemented
2866 the support for that.
2868 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2869 into the file lib/silccore/id.h.
2871 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2873 * Fixed memory leaks in the functions silc_idlist_del_client,
2874 silc_idlist_del_channel and silc_idlist_del_server in the file
2875 silcd/idlist.c. All of those leaked like a sieve.
2877 * Fixed some small memory leaks in the client's function
2878 silc_client_notify_by_server.
2880 * Added functions into silcd/server.c: silc_server_announce_clients,
2881 silc_server_announce_channels and silc_server_announce_server.
2882 These functions are used by normal and router server to announce
2883 to its primary router about clients, channels and servers (when
2884 router) that we own. This is done after we've connected to the
2887 These functions effectively implements the following packet types:
2888 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2889 and SILC_PACKET_NEW_ID_LIST.
2891 * Added new functions into the silcd/packet_receive.[ch]:
2892 silc_server_new_id_list, silc_server_new_channel_list and
2893 silc_server_new_channel_user_list to handle the incoming
2894 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2896 * Added support of changing Channel ID in the function
2897 silc_server_replace_id. If the server that announces a channel
2898 to the router already exists in the router (with same name but
2899 with different Channel ID), router is responsible to send
2900 Replace ID packet to the server and force the server to change
2901 the Channel ID to the one router has.
2903 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2904 client that the Channel ID has been changed by the router. The
2905 normal server sends this to the client. Client must start using
2906 the new Channel ID as the channel's ID.
2908 Implemented handling of this new type into lib/silcclient/client.c
2909 into the function silc_client_notify_by_server.
2911 * Added new function silc_idlist_replace_channel_id into the files
2912 silcd/idlist.[ch] to replace the Channel ID.
2914 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2916 * Call silc_server_command_identify_check always when processing
2917 the IDENTIFY command in silcd/command.c
2919 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2922 send keepalive packets. The packet can be sent by clients,
2923 servers and routers.
2925 Added function silc_socket_set_heartbeat into the file
2926 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2927 If not set, the heartbeat is not performed. The actual
2928 heartbeat is implemented in the low level socket connection
2929 library. However, application is responsible of actually
2932 Added silc_server_send_heartbeat to send the actual heartbeat
2933 packet into silcd/packet_send.[ch]. Server now performs
2934 keepalive with all connections.
2936 * Added silc_task_get_first function into lib/silcutil/silctask.c
2937 to return the timeout task with shortest timeout. There was a bug
2938 in task unregistration that caused problems. TODO has been
2939 updated to include that task system must be rewritten.
2941 * The client library will now resolve the client information when
2942 receiving JOIN notify from server for client that we know but
2943 have incomplete information.
2945 * Rewrote parts of silc_server_remove_from_channels and
2946 silc_server_remove_from_one_channel as they did not remove the
2947 channel in some circumstances even though they should've.
2949 * Encryption problem encountered in server:
2951 The LEAVE command used to send the Channel Key packet to the
2952 router immediately after generating it. However, the code
2953 had earlier sent Remove Channel user packet but not immediately,
2954 ie. it was put to queue. The order of packets in the router
2955 was that Channel Key packet was first and Remove Channel User
2956 packet was second, even though they were encrypted in the
2957 reverse order. For this reason, MAC check failed. Now, this
2958 is fixed by not sending the Channel Key packet immediately but
2959 putting it to queue. However, this is more fundamental problem:
2960 packets that are in queue should actually not be encrypted
2961 because packets that are sent immediately gets encrypted
2962 actually with wrong IV (and thus MAC check fails). So, packets
2963 that are in queue should be encrypted when they are sent to
2964 the wire and not when they put to the queue.
2966 However, the problem is that the current system has not been
2967 designed to work that way. Instead, the packet is encrypted
2968 as soon as possible and left to the queue. The queue is then
2969 just purged into wire. There won't be any fixes for this
2970 any time soon. So, the current semantic for packet sending
2973 o If you send packet to remote host and do not force the send
2974 (the packet will be in queue) then all subsequent packets to the
2975 same remote host must also be put to the queue. Only after the
2976 queue has been purged is it safe again to force the packet
2979 o If you send all packets immediately then it safe to send
2980 any of subsequent packets through the queue, however, after
2981 the first packet is put to queue then any subsequent packets
2982 must also be put to the queue.
2984 Follow these rules and everything works fine.
2986 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2988 * Added new function silc_server_remove_clients_by_server to
2989 remove all client entries from ID list when the server connection
2990 is lost. In this case it is also important to invalidate all
2991 client entires as they hold the invalid server entry. This
2992 fixes fatal bug when server has lost connection and will reconnect
2995 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2997 * Made some sanity checks to silc_server_daemonise like to check
2998 whether the requested user and group actually exists.
3000 * Added sanity check to SKE's silc_ske_responder_finish to check
3001 that the public and private key actually is valid.
3003 * Invalidate the client's nickname when receiving Replace ID
3004 packet and the Client ID is being replaced. This means that the
3005 server will query the nickname if someone needs it (client)
3008 * Sort the ID Cache in client library when the ID Cache data
3009 has changed (needs sorting).
3011 * Do not allow for SILC client to create several connections to
3012 several servers. The client does not support windows right now
3013 and generating multiple connections causes weird behaviour.
3015 Irssi-silc client does support windows and can handle several
3016 connections without problems, see: www.irssi.org and SILC plugin.
3018 * Fixed some places where client was added to the IDList. The
3019 rule of thumb is following (in order to get everything right):
3020 If the client is directly connected local client then the
3021 `connection' argument must be set and `router' argument must be
3022 NULL to silc_idlist_add_client function. If the client is not
3023 directly connected client then the `router' argument must
3024 bet set and the `connection' argument must be NULL to the
3025 silc_idlist_add_client function.
3027 * The funtion silc_server_packet_send_local_channel actually did
3028 not check whether the client was locally connected or not. It
3029 does that now. Fixed a bug related to LEAVE command.
3031 * Fixed Remove Channel User payload parsing bug in server's
3032 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3034 * The server's silc_server_save_channel_key now checks also the
3035 global ID list for the channel as it might not be in the local
3036 list. Fixed a bug related to LEAVE command.
3038 * Is this the end of the [<unknown>] buglet that has been lurking
3039 around for a long time? A little for loop fix in server's
3040 silc_server_command_whois_parse that is used by both IDENTIFY
3041 and WHOIS command. At least, this was a clear bug and a cause
3042 of one type of [<unknown>] buglet.
3044 * WHOIS and IDENTIFY commands call the function
3045 silc_server_command_[whois/identify]_check function even if
3046 we are not router server.
3048 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3050 * Added --with-gmp configuration option. If set the GMP
3051 is always compiled in the SILC source tree. If not set then
3052 it is checked whether the system has the GMP3 installed. If
3053 it has then the GMP won't be compiled (the system's headers
3054 and library is used), if it doesn't have it then the GMP is
3055 compiled in the SILC source tree.
3057 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3059 * Changed RSA private exponent generation to what PKCS #1
3060 suggests. We try to find the smallest possible d by doing
3061 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3062 not security fix but optimization.
3064 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3066 * Added new config entry [Identity] to fork the server and run
3067 it as specific user and group. A patch from Bostik.
3069 * Imported Dotconf configuration library into lib/dotconf.
3070 This will be used to create the SILC configuration files later.
3071 It will appear in the distsribution after this commit.
3073 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3075 * A big code auditing weekend happening. Auditing code for
3076 obvious mistakes, bugs and errors. Also, removing any code
3079 Removed files for being obsolete:
3081 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3082 inline in the file lib/silcutil/silcbuffer.h)
3084 o lib/silcutil/silcbufutil.c (the header has inline versions)
3086 Changed code to fix possible error conditions:
3088 o The buffer formatting routines now check that the destination
3089 buffer really has enough space to add the data. This applies for
3090 both buffer formatting and unformatting
3091 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3092 unformatting was changed to accomodate following rules:
3093 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3094 sent to the function while XXX_*STRING will not allocate or copy
3095 the data into the buffer. Instead it sets the pointer from the
3096 buffer into the pointer sent as argument (XXX_*STRING used to
3097 require that the pointer must be allocated already). This change
3098 makes this whole thing a bit more consistent and more optimized
3099 (note that the data returned in the unformatting with XXX_*STRING
3100 must not be freed now). The routines return now -1 on error.
3102 o Tried to find all code that use buffer_format and buffer_unformat
3103 and added return value checking to prevent formatting and
3104 especially unformatting errors and possible subsequent fatal
3107 o Changed ske->x and ske->KEY to mallocated pointers in
3108 lib/silcske/silcske.h. Fixed possible data and memory leak.
3110 o Added return value checking to all *_parse* functions. Fixed
3111 many memory leaks as well.
3113 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3114 so that buffer overflows would not happen. All code now also
3115 checks the return value as it can fail.
3117 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3119 * Added reconnection support to server if the normal server looses
3120 its connection to the router (for example if router is rebooted).
3121 The server performs normal reconnection strategy implemented
3122 to the server. Affected file silcd/server.c.
3124 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3126 * Added new packet type SILC_PACKET_SET_MODE that is used to
3127 distribute the information about changed modes (for clients,
3128 channels and clients channel modes) to all routers in the
3129 network. Updated the protocol specification accordingly.
3131 Added functions into silcd/packet_send.c and
3132 silcd/packet_receive.c: silc_server_send_set_mode,
3133 silc_server_set_mode.
3135 Added new files silcmode.[ch] into lib/silccore that implements
3136 the encoding and decoding of Set Mode Payload. Added new type
3137 SilcSetModePayload. Moved the definitions of different modes
3138 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3140 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3142 * Oops, a little mistake in server's connection authentication
3143 protocol. The protocol is not ended with FAILURE but with
3144 SUCCESS if the authentication is Ok. :) Affected file is
3147 * Implemented NICK_CHANGE notify handling in server in the file
3148 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3149 the local clients on the channel. After the changing nickname
3150 in router environment snhould work and the [<unknown>] nickname
3151 should appear no more.
3153 The silc_server_replace_id function that receives the Replace ID
3154 payload now sends the NICK_CHANGE notify type also in the file
3155 silcd/packet_receive.c
3157 * Changed WHOIS and IDENTIFY command to support the maximum amount
3158 of arguments defined in protocol specs (3328 arguments). This
3159 fixed a bug that caused problems when there were more than three
3162 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3164 * Added extra parameter, command identifier, to the
3165 silc_client_send_command so that explicit command identifier
3168 Changed that ID list routines uses specific command identifier
3169 when sending WHOIS/IDENTIFY requests to the server so that they
3170 can be identified when the reply comes back.
3172 Affected files lib/silcclient/command.[ch],
3173 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3175 * Added `sender' argument to silc_server_packet_send_to_channel
3176 to indicaet the sender who originally sent the packet to us
3177 that we are now re-sending. Ignored if NULL. Affected file
3178 silcd/packet_send.[ch].
3180 * Added some server statistics support in silcd/server_internal.h
3181 SilcServerStatistics structure and around the server code. Also
3182 send some nice statistics information when client is connecting
3185 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3187 * Fixed channel ID decoding in server's JOIN command reply in
3188 silcd/command_reply.c
3190 * Fixed braodcasting of replace ID payload to not to send it if
3191 we are standalone server in silcd/packet_receive.c.
3193 * Fixed all channel message sending routines to not to send
3194 packets to clients that has router set, since they are routed
3195 separately in the same function earlier. Affects file
3196 silcd/packet_send.c and all channel packet sending functions.
3198 * In USERS reply, res_argv[i] are not allocated, the table
3199 is allocated. Thus changed that free the table, not its
3202 * In server's whois_check and identify_check if the client is
3203 locally connected do not send any WHOIS commands - they are not
3206 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3208 * Fixed some minor bugs in client when sending WHOIS command. The
3209 arguments was in wrong order.
3211 * Removed statis function add_to_channel from server in
3212 silcd/command.c that was previously used with the joining but
3215 * Tested USERS command in router environment successfully with two
3216 routers, two servers and two clients.
3218 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3220 * Reorganized the USERS command and command reply in client library
3221 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3222 When the command is given by user we register a pending command
3223 callback that will reprocess the command after the reply has been
3224 received from the server. When reprocessing the packet we then
3225 display the information. Thus, the USERS information is displayed
3226 now in the command callback instead of in the command reply
3227 callback. The processing of the command is same as previously
3228 when server has sent the command reply in the JOINing process.
3230 * Added to USERS command in silcd/command_reply.c to join the client,
3231 we didn't use to know about, to the channel after we've created
3232 a client entry for it. Also, for clienet we did know already still
3233 check whether it is on the channel or not and add it if not.
3235 * Removed silc_server_command_join_notify as the function and its
3238 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3240 * Changed the client's pending command handling to the same as the
3241 server's pending command handling. It is also now possible to
3242 execute command reply functions from other command reply
3243 function as the function callbacks for commands and command
3244 replies are one and same. The pending commands are not static
3245 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3246 in client connection context. Thus, pending commands are server
3247 connection specific as it is convenient.
3249 Changed the function silc_client_command_pending and
3250 silc_client_command_pending_del and added new function
3251 silc_client_command_pending_check. Removed the
3252 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3255 * Added cmd_ident, current command identifier, to the client
3256 connection context in lib/silcclient/client.h to keep track on
3257 command identifiers used in command sending. Client's command reply
3258 function handling now supports the mandatory command identifiers.
3260 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3261 funtions in client to fully support pending command callbacks.
3263 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3264 as one of the arguments to the application in the command reply
3267 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3268 before first releasing SILC but came back. Now it is removed again
3269 and should come back nomore. The FORWARDED flag was used only
3270 by the JOINing procedure by forwarding the command packet to router.
3271 Now, the JOINing procedure has been changed to more generic (due
3272 to various router environment issues) and FORWARDED is not needed
3273 anymore for anything. The protocol specification is yet to be
3276 Now, removed silc_server_packet_forward from server and the flag
3277 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3279 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3281 * Renamed NAMES command to USERS command. The NAMES was named that
3282 due to historical reasons. Now it is renamed. Also, rewrote
3283 parts of the USERS command. The nickname list is not sent anymore
3284 by the server. Only Client ID and mode lists are sent in the USERS
3285 command. Changed this also to the protocol specification.
3287 The client now resolves the names and stuff after it receives
3288 the USERS list from the server when joining to the channel.
3290 * WHOIS and IDENTIFY commands has been changed to support multiple
3291 Client ID's per command. One can now search for multiple users
3292 in the network by sending only one WHOIS or IDENTIFY command.
3293 Changed the code and the protocol specifications.
3295 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3296 uses silc_server_command_whois_parse to parse the request. */
3298 * If normal server, do not parse the WHOIS and IDENTIFY requests
3299 before sending it to the router. Saves some time.
3301 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3303 * Fixed JOIN command on client library. Wrong number of arguments
3304 used to crash the client.
3306 * Added silc_server_channel_has_global function to check whether
3307 channel has global users or not.
3309 * Added silc_server_channel_has_local function to check whether channel
3310 has locally connected clients on the channel.
3312 * The silc_server_remove_from_one_channel now checks whether the
3313 channel has global users or not after given client was removed from
3314 the channel. It also checks whether the channel has local clients
3315 on the channel anymore. If it does not have then the channel entry
3316 is removed as it is not needed anymore.
3318 * The silc_server_notify now checks on JOIN notify whether the joining
3319 client is one of locally connected or global. If it is global then
3320 the channel has now global users on the channel and that is marked
3321 to the channel entry. Also, it now saves the global client to
3322 global list who is joining and JOINs it to the channel. This is
3323 for normal server, that is.
3325 Changed silc_server_send_notify_on_channel,
3326 silc_server_packet_relay_to_channel and
3327 silc_server_packet_send_to_channel check if we are normal server
3328 and client has router set (ie. global client) do not send the
3329 message to that client, as it is already routed to our router.
3331 * Implemented LEAVE notify type handling in silc_server_notify
3334 * Tested LEAVE command in router environment successfully. Tested
3335 with two routers, two servers and two clients.
3339 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3341 * Implemented SIGNOFF notify type handling in silc_server_notify
3344 * silc_server_remove_id now removes the client entry from all channels
3345 it has joined and thusly sends SIGNOFF notify type.
3347 * Rewrote the NAMES list generation in server by removing two excess
3348 loops. The lists are created now inside one loop.
3350 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3352 * silc_server_remove_channel_user checks now also global list
3353 for channel and client.
3355 * silc_server_new_channel_user checks now both local and global
3356 list for channel and client. Fixed a bug in client id decoding.
3357 Used to decode wrong buffer.
3359 * silc_server_channel_message checks now both local and global
3360 list for channel entry.
3362 * Tested channel joining (hence JOIN) in router environment
3363 successfully. Tested with two routers, two servers and two
3366 * Tested channel message sending in router environment successfully.
3368 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3370 * Added silc_server_save_channel_key into server.[ch] to save the
3371 received channel key in Channel Key payload processing. It is
3372 also used in JOIN command reply handling.
3374 Equivalent function silc_client_save_channel_key added into
3375 client.[ch] into client library.
3377 * Changed JOIN command reply to send information whether the channel
3378 was created or not (is existing already) and the channel key
3379 payload. Changed protocol specs accordingly.
3381 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3382 the request was sent by ID and not by nickname. Crashed on
3385 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3387 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3388 now correctly save the received data.
3390 * silc_server_free_sock_user_data now notifies routers in the
3391 network about entities leaving the network.
3393 At the same time implemented functions silc_server_remove_id
3394 and silc_server_send_remove_id to receive and send REMOVE_ID
3395 packets. The packet is used to notify routers in the network
3396 about leaving entities. The ID removed will become invalid in
3399 * Added function silc_idlist_del_server into server. Removes and
3400 free's server entry from ID list.
3402 * silc_server_private_message function now checks, if we are router,
3403 that the destination ID really is valid ID, naturally.
3405 * In router when NEW_ID packet is received (for new client) the
3406 hash of the Client ID is saved in the ID Cache but the
3407 client->nickname is set to NULL, instead of putting the hash
3410 IDENTIFY command now also checks that client->nickname must be
3411 valid. If it is not if will request the data from the server who
3412 owns the client. Added new function
3413 silc_server_command_identify_check.
3415 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3416 to set the command to already allocated Command Payload.
3418 * Tested private message sending in router environment with two
3419 routers, two servers and two clients. Fixed minor bugs and now
3422 * Fixed segfault from client's NAMES command. Used to crash if
3425 * Forwarded packets must not be routed even if it is not destined
3426 to the receiver. Changed server code comply with this.
3428 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Added `require_reverse_mapping' boolean value to ServerParams
3431 structure. If TRUE (not default) the server will require that
3432 the connecting host has fully qualified domain name.
3434 If the reverse mapping is not required and hostname could not be
3435 found the IP address is used as hostname.
3437 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3439 * Implemented version string checking to both client and server.
3440 The check is incomplete currently due to the abnormal version
3441 strings used in development version of SILC.
3443 * Changed all command functions in server to use the new
3446 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3448 * Changed char *data to unsigned char *data in ID Cache system to
3449 support binary data as ID Cache data. Changed code to support
3450 binary data in lib/silccore/idcache.c.
3452 * Renamed silc_server_packet_relay_command_reply to
3453 silc_server_command_reply as it is normal packet receiving
3454 function. Rewrote the function to accept command replys for
3455 servers and not only for clients.
3457 * Mark remote router always as registered server if we are connecting
3458 to it. Otherwise, commands sent by the router to us are ignored.
3460 * All ID List find routines now returns the ID Cache Entry pointer
3461 as well if requested.
3463 * WHOIS command works now in router environment, tested with two
3464 routers, two servers and two clients.
3466 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3467 in router environment (as it is almost equivalent to WHOIS) but
3468 hasn't been tested thoroughly. Added new functions:
3470 silc_server_command_identify_parse
3471 silc_server_command_identify_send_reply
3472 silc_server_command_identify_from_client
3473 silc_server_command_identify_from_server
3475 * Disabled route cache adding because adding two different ID's with
3476 same IP replaces the old cache entry thus giving wrong route.
3477 The entry->router->connection is always the fastest route anyway
3478 so route cache may not be needed. Of course, new routes maybe
3479 established after receiving the ID when the entry->router->connection
3480 might not be anymore the most optimal.
3482 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3484 * Add route cache for received ID for fast routing.
3486 * Added silc_server_packet_route to route received packet on router
3487 that is not destined to us.
3489 * Renamed silc_server_get_route to silc_server_route_get.
3491 * Added id_string and id_string_len fields into SilcServer to
3492 include encoded ServerID for fast comparing without excess
3493 encoding of the ID's.
3495 * Cleaned up WHOIS command on server side. Added following static
3498 silc_server_command_whois_parse
3499 silc_server_command_whois_check
3500 silc_server_command_whois_send_reply
3501 silc_server_command_whois_from_client
3502 silc_server_command_whois_from_server
3504 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3505 arguments in command replies. All command functions should be
3506 updated to use this macro.
3508 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3510 * Minor typo fixes on command reply handling on server.
3512 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * Added silc_server_command_add_to_channel internal routine to add
3515 the client to the channel after router has created the channel and
3516 sent command reply to the server.
3518 * Added generic silc_server_send_command to send any command from
3521 * Use static buffer with ID rendering instead of duplicating data.
3523 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3525 * Fixed a channel user mode bug when joining to a channel server gave
3526 everybody channel founder rights, oops.
3528 * We mark ourselves as the router of the incoming server connection
3529 if we are router ourselves. This way we can check in some packet
3530 sending functions whether it is locally connected server. For
3531 incoming router connections we put NULL.
3533 * For router sending packets locally means now always sending the
3534 packet cell wide; to local clients and local servers. For normal
3535 server sending packet locally means sending it to only local
3538 * Fixed the JOIN command to really work in router environment. If the
3539 channel is created it is always created by the router. Router is
3540 also responsible of making the initial joining to the channel,
3541 sending JOIN notify to the sending server and distributing
3542 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3543 does not exist server doesn't do anything else but forward the
3544 command to the router which performs everything.
3546 * Added silc_server_send_channel_key function to send the Channel Key
3549 * Added silc_server_create_channel_key to create new channel key. The
3550 channel key is now re-generated everytime someone joins or leaves
3551 a channel, as protocol dictates. Note: channel->key_len is the
3554 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3556 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3557 packet_receive.[ch] to separate packet sending and receiving
3558 routines. The server.[ch] now includes everything else including
3559 actual packet processing (writing and reading data) and other
3562 Renamed silc_server_private_message_send_internal to
3563 silc_server_send_private_message. The routine is still though
3564 used only to relay private messages as server does not send
3565 private messages itself.
3567 Renamed silc_server_new_channel to silc_server_create_new_channel
3568 and added new function sicl_server_new_channel that handles the
3569 incoming New Channel packet. Added also new sending function
3570 silc_server_send_new_channel to send New Channel Payload.
3572 * Added new function silc_server_notify to process incoming notify
3573 packet to the server/router. Server may then relay the notify
3574 to clients if needed.
3576 * Added new function silc_server_new_channel_user to process incoming
3577 New Channel User packet. Router will redistribute the packet and
3578 send JOIN notify to its local clients and locally connected servers
3579 if needed. Normal server will send JOIN notify to its local client
3580 on same channel when received this packet. Added also corresponding
3581 sending function silc_server_send_new_channel_user to sent the
3584 * Added boolean route argument to send_notif_to_channel and
3585 packet_send_to_channel functions to attempt to route the packet
3586 if it is TRUE and send only locally if it is FALSE.
3588 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3590 * silc_server_replace_id now broadcasts the received replace ID
3591 packet if it is not broadcast packet already. The router must
3592 broadcast to inform other routers about changed ID.
3594 * Added backpointer to server's router into SilcServer context in
3595 silcd/server_internal.h.
3597 * Fixed silc_server_packet_broadcast to send correct broadcast
3600 * The channel key is now distributed to the local client as soon
3601 as it is received from the router (in router environment) so that
3602 no other packet may be sent for the channel until client has
3605 * silc_server_remove_channel_user now broadcasts the received
3606 Remove Channel User packet if it is not broadcast packet already.
3607 The router must broadcast to inform other routers about removed
3610 * Added users field into SilcPacketContext that is a reference count
3611 of the context. One can increase the reference count by calling
3612 silc_packet_context_dup which is now changed to just increase the
3613 reference count instead of duplicating the data. The reference
3614 count is decresed by calling silc_packet_context_free that will
3615 free the data after the reference count hits zero.
3617 For now on the packet context and everything allocated into it
3618 (including the raw packet from network) must be freed by calling
3619 the new silc_packet_context_free function. Added also new function
3620 silc_packet_context_alloc that must be used now to allocate the
3621 context. This also means that if a routine is asynchronous from
3622 silc_[client/server]_packet_parse_type the packet context must
3623 be duplicated by calling silc_packet_context_dup. Otherwise it
3624 gets free'd after silc_[client/server]_packet_parse_type returns.
3625 Also, one must remember that if packet is duplicated then its
3626 reference count must be decresed by calling the free function as
3627 many times as it was duplicated.
3629 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3630 from both client and server.
3632 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3634 * Made joining to a channel working in router environment.
3636 * Cleaned up JOIN command on server side and create function
3637 silc_server_command_join_channel internal routine to make the
3640 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3642 * Changed silc_command_pending list to SilcDList. Also, added
3643 `ident' field to SilcServerCommandPending structure to identify
3644 the reply and to call correct callback.
3646 Added silc_server_command_pending_check function to replace the
3647 corresnponding macro. The silc_command_pending list is not
3650 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3651 to set identifier to previously allocated Command Payload. It
3652 is used to set identifier for command when resending Command
3655 * Added silc_command_payload_encode_payload to encode Command
3656 Payload buffer from SilcCommandPayload structure.
3658 * Added silc_argument_payload_encode_payload to encode Argument
3659 payload buffer from SilcArgumentPayload structure.
3661 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3663 * Changed WHOIS command to support router connection on server side.
3664 The whois request is always sent to router unless the server is
3665 standalone server. After server has received the reply from the
3666 router will it send the reply to the client.
3668 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3669 broadcast received broadcast packet. The function is used only
3670 by router. The broadcast packet is always sent to the router's
3673 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3674 render given ID to printable string, for log files for example.
3676 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Made basic router to router connections working. At least they
3679 can now connect to each other but nothing really works the way
3680 they are supposed - yet.
3682 * Added new initiator token to RouterConnection configuration
3683 file in silcd/serverconfig.[ch]. It is used to tell whether we
3684 are the initiator to the remote router or whether we'll expect
3685 the other end to connect.
3687 * Moved registering of listener task to silc_server_init, hence
3688 the server starts listenning as soon as it is run, even if it
3689 does not have connections to other routers. Let's see how well
3692 * Changed default connection retry timeouts for more suitable in
3695 * Removed cipher and such arguments from silc_idlist_add_client
3696 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3697 Added new function silc_idlist_add_data to add the keys and stuff
3700 * Added SilcIDListData structure and added it to SilcClientEntry
3701 and SilcServerEntry as their first field in the structure. This
3702 way we can explicitly cast the ID entries to the SilcIDListData
3703 structure and get common data for the entries. In past, we had
3704 to first check what type of connection it is and then cast it to
3705 correct ID entry type. Now, we can directly cast the opaque
3706 pointer to the SilcIDListData (no matter what ID entry it actually
3707 is) and get the data needed.
3709 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3711 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3712 in some circumstances even if threre were timeout tasks, though not
3713 IO tasks, but tasks anyway. Now fixed.
3715 * Defined SilcServerConnection structure to hold connection specific
3716 stuff about directly connected servers and routers. The definition
3717 is currently in silcd/server_internal.h. I thought about having
3718 a bit more important role fro this struct but for now it is used
3719 only when connecting to other server (or router actually).
3721 * Added connecting retry support in server when connecting to
3722 router(s). The retry feature implement exponential backoff
3723 algorithm. Also, added SilcServerParams structure to hold default
3724 parameters for server. For now, it include these retry settings
3725 and are hard coded. After server is moded to be as Silc Server
3726 Library this structure will be more important.
3728 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3730 * Changed client librarys channel->clients table to SilcList and
3731 changed code accordingly.
3733 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3735 * Changed client's channel table to SilcList and changed code
3736 accordingly. Also changed SilcChannelClientEntry to include back-
3737 pointer to the channel so that client entry can use that structure
3738 as list as well and we have fast cross-reference to the channel.
3739 This change dramatically decreased the complexity of channel
3740 handling with client entry and vice versa (removed one extra
3741 loop when searching for channel entry from many functions).
3743 * Changed server->sim from table to SilcDList and changed code
3746 * NAMES command can now be used from user interface. It will show
3747 the user list on the channel, neatly.
3749 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3750 Code now saves realname of the user if it becomes available.
3752 * Renamed configure.in to configure.in.pre and made ./prepare
3753 script to automatically add correct version string to
3754 configure.in which it creates from configure.in.pre.
3756 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3758 * NAMES command reply now shows users mode with the nickname when
3761 * Moved silc_client_ch[u]mode[_char] functions from
3762 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3763 place sucks, they are utility functions and should be in some
3766 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3768 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3771 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3775 * Added TRQ (efficient deque and list library) into lib/trq. This is
3776 a very good list library that is currently used in the SILC. Defined
3777 SilcList API over the library because I didn't like the API very
3778 much. See lib/trq/silclist.h for the API and examples of how to
3779 use the API. Fixed various places in the code to use the new
3780 SilcList API. The SilcList is meant for lists that has a structure
3781 already defined as a list. It is not suitable to add just some
3782 context to the list (in TRQ, the context is the list actually).
3784 So, I defined SilcDList that can be used for the purpose where
3785 predefined list structure does not exit. This can be used as
3786 such list. Now some context just can be added to the SilcDList.
3787 Currently this list is not used in the SILC just yet, though there
3788 are a lot places where this can replace dynamically allocated
3789 tables and I will fix these places, later, to use SilcDList.
3790 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3791 and use TRQ internally).
3793 Also fixed some annoying warning messages that the original TRQ
3794 code generated. Also minor changes to TRQ's Makefile.in.
3796 * Added support for querying by Client ID to both WHOIS and
3797 IDENTIFY commands into server, as required by the protocol.
3799 * Removed method function pointers from SilcBuffer structure. They
3800 weren't used to anything and just increased the context size for
3801 no good reason. This change also made silc_buffer_alloc and
3802 silc_buffer_free functions inline functions.
3804 * Disabled command flooding detection support until it's fixed so
3805 that it accepts commands in but does not execute them more than once
3808 * Added silc_net_localhost(), to return local hostname, into
3809 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3810 that must be initialized before calling silc_client_init.
3812 * Added new function: silc_server_send_notify_on_channels to send
3813 notify messages to all channels client has joined. It is assured
3814 that the message is sent only once per client.
3816 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3817 lib/silcutil/silcutil.[ch] as silc_format function. The new
3818 function is generic and is used by server as well, not only by
3819 the logging routines.
3821 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3822 the provided version string was not acceptable. Added new function:
3823 silc_ske_check_version into lib/silcske/silcske.h. The function
3824 must be implemented by the application (client or server) and it
3825 does not reside in the SKE library. The function checks the version
3826 string remote end sent.
3828 * Added back pointers (to opaque context and to SilcSocketConnection)
3829 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3831 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3832 duplicate packet context structure.
3834 * Changed `notify' client operation to send same arguments as client
3835 receives from server except for ID's. ID's are mapped to correct
3836 ID entry and that is returned. Also, if channel entry is not sent
3837 by server but the notify is for channel the channel entry is sent
3838 to application (otherwise application doesn't know that it is for
3839 channel (library gets it from packet's Destination ID)).
3841 * Added silc_client_remove_from_channels into client library to
3842 remove a client from all channels it has joined to. Used when
3843 received SIGNOFF notify from server. Added also new function
3844 silc_client_replace_from_channels to replace old ID entry with
3845 new ID entry on all channels. Used when received NICK_CHANGE
3848 * Fixed ID Cache list handling in silc_idlist_get_client in
3849 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3850 to get (or query) client by ID.
3852 * Updated TODO list.
3854 * Added connection authentication status message defined by the
3855 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3856 support for these into the code in client and server side.
3858 * Added generic function silc_client_send_command to send any command
3859 with variable argument list. Application should use this function
3860 to send commands if the command functions provided by the library
3861 does not suite for the application's user interface needs.
3863 * Added new `failure' client operation. Application is notified about
3864 received failure packet if client is executing a protocol. In this
3865 case the protocol's execution has failed.
3867 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3868 is required by the protocol.
3870 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3871 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3874 * Added status flag to SilcSKE object to indicate realtime status
3875 of the SKE protocol.
3877 * Application receives now exactly same command reply arguments as
3878 the library receives from server. However, if ID is received the
3879 corresponding ID entry is returned to the application (eg. Client
3880 ID is mapped to correct SilcClientEntry entry and that is returned).
3881 Changed command_reply client operation due to this change.
3883 * Changed all ID's in commands and in command replys as ID Payloads.
3884 Change affected both client and server side codes.
3886 All ID's sent in SILC network (with execption of ID's in SILC
3887 Packet header) are sent in ID Payload to support variable length
3890 * Server now notifies nick changes and notifies all clients on
3891 the channels about the new nickname (about the new Client ID,
3894 * Implemented CMODE command to change channel modes. Supports all
3895 channel modes defined by the protocol specs except ban and invite
3896 lists. (Also, private channel key mode is supported but support for
3897 setting private channel key in client is missing, thus, this mode
3898 has no effect on client side (except that server requires that the
3899 client uses private channel key and normal channel traffic does not
3902 Also, invite mode works per se, but INVITE command does not work
3903 yet correctly, so you can set channel as invite only channel but
3904 inviting clients to the channel does not work (it is yet to be
3905 thought what's the best way to do it).
3907 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3908 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3909 Implemented CUMODE command to change user's mode on the channel.
3910 Supports all modes defined by the protocol specs.
3912 * Added NAMES command reply to return users modes on the channel.
3914 * Removed unnecessary and slow ciphers from lib/silccrypt.
3916 * Set SO_KEEPALIVE option to connection sockets by default.
3918 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3920 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3921 redefined the Notify Payload into protocol specs.
3923 * Added silc_id_payload_parse_id to get ID directly from raw
3926 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3928 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3929 accept searching by Client ID as well.
3931 * Added support for LEAVE and SIGNOFF notify types in client library.
3933 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3934 to parse ID Payload from raw data.
3936 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Added flags parameter into silc_ske_assemble_security_properties
3939 function in lib/silcske/silcske.[ch].
3941 * Changed notify client operation to fit better for notify messages
3942 sent by server. The notify payload received from server is now
3943 passed to the application (after parsing it to SilcNotifyPayload).
3944 It is application's responsibility to retrieve the arguments
3945 from the payload and show the message the way it wants. The message
3946 sent by server is implementation specific.
3948 * Changed public keys to comply with the protocol specification.
3949 Old public keys are not supported anymore and are not compatible.
3951 * Removed nickname from Channel Payload as the latest draft removed
3952 it. The client must resolve the nickname from the NAMES command
3953 reply received when it joined the channel.
3955 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3957 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3959 * Fixed some errors in protocol specification drafts.
3961 * Created lib/silccore/silcnotify.c to implement Notify Payload
3962 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3963 generic payloads described by protocol specifications. The file
3964 includes implementations for ID Payload and Argument Payload.
3966 * Changed Command Payload implementation to use the new Argument
3967 Payload. Changed command_xxxx_payload to command_payload_xxxx
3968 to comply with SILC coding conventions.
3970 * Added suppport for Argument Payload handling in Notify Payload
3971 implementation as protocol requires it. Added the new support
3972 into server and client lib as well.
3974 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3976 * Added support for multiple nicknames on same channel. [n] is
3977 added locally to the nickname if there are more than one same
3978 nicknames on the channel.
3980 * Server now sends all nicknames that matched WHOIS request.
3981 Client also shows the list received from server.
3983 * Added TOPIC command to client side. User can now set and show
3984 current topic on channel.
3986 * Added MOTD command to client and server. Also, server sends the
3987 motd when client connects to the server.
3989 * Changed version strings to comply ISO 8601.
3991 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3993 * Fixed protocol error handling in client library. It should now
3994 cope even if the SKE fails for some reason.
3996 * Made new protocol specification drafts for submitting to IETF.
3998 * Implemented TOPIC command to server in silcd/command.c.
4000 * Added two new notify types into lib/silccore/silcnotify.h:
4001 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4002 notify nickname change and topic setting/change on a channel.
4004 * API change of command_reply operation in client library. The
4005 application gets now the status type received from server as well.
4007 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4009 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4011 * Cras fixed and optimized the packet handling even further and
4012 it should work now. Minor change to the prototype of function
4013 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4015 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4017 * Added new function into lib/silcutil/silcschedule.[ch]:
4018 silc_schedule_with_fd to select() a specified fd. The function
4019 returns after timeout expires or data arrives or goes. The
4020 function is used by packet routines to wait that all data is
4021 received from network.
4023 * Fixed data reading from network in lib/silccore/silcpacket.c.
4024 The code now assures that all data is read from the fd and then
4025 continues packet processing. This was a bug fix since the code
4026 used to drop some data in some circumstances.
4028 * Added new function into lib/silcclient/client.[ch]:
4029 silc_client_start_key_exchange to start key exchange after
4030 connection has been established to server. The code internally
4031 now uses this funtion but its main purpose was to provide it
4032 for applications that perform their own connecting. After
4033 application has created a connection it merely calls this
4034 function to start the key exchange between client and server.
4035 The library takes care of everything else after that.
4037 Updated also lib/silcclient/README to explain the usage of
4040 * Do not send to application information that connection has
4041 been established. Application gets notified it by connect
4044 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Applied cras's patch to add silc_schedule_one function. The
4047 function runs scheduler once and returns.
4049 * Fixed the scheduler after cras messed it up. The timeout
4050 handling works now as it's supposed to work.
4052 * Added into lib/silccore/ silcnotify.h to include notify
4053 message types support. Changed silc_server_send_notify*
4054 functions, in server.[ch], to support those new notify types.
4055 Added the support for the notify types into client library,
4056 as well. Added new notify client operation into ops.h in
4059 * Changed silc_server_packet_send_to_channel to send normal
4060 packets instead of just channel message packets. The function
4061 is now used to send the notify packets to channels. It is not
4062 used to send channel message packets anymore, as server never
4065 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4066 va_arg()s as it seems to require it nowadays. I guess, if SILC
4067 is compiled with older va_arg() the new code should work anyway.
4069 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4071 * Splitted core library. Core library (lib/silccore) includes
4072 now only SILC protocol specific core (and common) components.
4073 Created new utility library (lib/silcutil) that includes more
4074 generic purpose stuff. The stuff for util library was taken
4075 from the old core library. This was minor and easy split.
4077 * Created SILC Client Library (lib/silcclient) that includes
4078 implementation of the SILC client without user interface. This
4079 was major move from silc/ directory. The code has been changed
4080 so that it is transparent towards the user interface. The
4081 silc/ directory includes now the same user interface as before
4082 and it uses the new client library. Read lib/silcclient/README.
4083 Basicly, the client library performs everything else related
4084 to SILC except user interface handling. Also, configuration
4085 files are considered to be part of user interface and library
4086 does not handle them.
4088 This change also changed a lot of structures, function naming etc.
4089 Most important change was that SilcClientWindow object was
4090 renamed to SilcClientConnection in the client library. Created
4091 also new file lib/silcclient/ops.h. Also added new files
4092 silc/local_command.[ch] and silc/client_ops.[ch].
4094 All these changes were made to make it easier for user interface
4095 designers to create what ever user interface for the SILC client
4098 It is also expected that the server will be moved to lib
4099 directory as well and SILC Server Library will be created;
4100 sometimes in the future.
4102 * Removed Local commands from lib/silccore/silccommand.h as
4103 they are application specific and new client library does not
4104 handle any of those anymore.
4106 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4107 old client implementation in silc/.
4109 * Added support for callback functions in SILC_LOG_* macros.
4110 Application can now set its own callbacks that will be called
4111 instead of using the default functions that will always print
4112 the debug messages to stderr (or stdout). Also, debugging can
4113 now be disabled by setting silc_debug to FALSE and re-enabled by
4114 setting it to TRUE. Note, that logging will still work even
4115 if debugging is disabled.
4117 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4118 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4119 silc_log_reset_debug_callbacks.
4121 * To enable debugging in silc client one must give now -d
4122 option on command line.
4124 * Changed silc_schedule_init to automatically allocate task queues
4125 if they are not allocated before calling it.
4127 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4129 * Added GMP 3.1 into math library.
4131 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4134 a channel in SILC network. The packet is used by servers and
4135 routers to notify other routers that user has left a channel.
4136 This little feature was missing until now. Added the feature
4137 to protocol specification as well.
4139 Added functions: silc_server_send_remove_channel_user and
4140 silc_server_remove_channel_user into server.[ch].
4142 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4143 lib/silccore/silcpacket.h. However, they are not implemented
4146 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4148 * Fixed joining to a channel and sending channel messages
4149 between server and router. The channel message sending should
4150 now work inside a cell.
4152 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4154 * Fixed the private message sending between server and router.
4155 The private message sending should now work inside a cell.
4157 * Added silc_server_replace_id into server.[ch] to replace
4158 existing ID in the SILC network.
4160 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4161 and silc_idlist_replace_server_id into idlist.[ch] in server.
4163 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4165 * Fixed the server to server connections. Server can again now
4166 connect to router. Router to router connections probably does
4169 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4171 * Added dynamic protocol registering support. Now protocols can
4172 registered and unregistered on the fly. Patch by cras.
4174 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4176 * Added lib/contrib directory to hold routines that some platforms
4177 don't have but are needed by SILC.
4179 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4180 into lin/contrib to provide getopt() and getopt_long() for
4181 those who don't have it.
4183 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Added AWAY command to client. When away message is set and
4186 client receives a private message packet the client automatically
4187 replies to the sender with the away message.
4189 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4190 bug seemed to be the cause of recent problems when compiling
4193 * Added version detection support to SKE protocol specification
4194 and added the new changes to the SKE implementation as well.
4195 There were other minor changes in the SKE protocol as well.
4197 Many changes in lib/silcske/silcske.[ch] and in
4198 lib/silcske/payload.[ch].
4200 * Added ^U functionality, clear input line. Patch from cras.
4202 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4204 * Mainly small bugfixes on core library. Fixed some debugging
4205 logging and buffer overflow in silclog.c.
4207 * Updated config.sub and config.guess on the distribution tree.
4209 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4211 * Added command lagging support in server. Client may execute
4212 commands now only once in two seconds.
4214 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4216 * Optimized packet reception. MAC computation and checking is now
4217 also more optimized. A lot previously duplicated code is now
4218 used as generic by both client and server.
4220 * Fixed key pair generation in clientutil.c
4222 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4224 * Added into lib/silccore/silcbufutil.[ch] new function;
4225 silc_buffer_realloc.
4227 * Moved generic packet sending/encryption functions to
4228 lib/silccore/silcpacket.[ch] from client and server. Some
4229 rewriting of the functions.
4231 * Moved all generic packet reception/decryption functions to
4232 lib/silccore/silcpacket.[ch] from client and server. The
4233 packet processing is now much cleaner in both client and server.
4234 These were major changes in both client and server.
4236 * Created many common functions in server to do packet sending.
4237 Previously code were duplicated a lot, this has been removed
4240 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4242 * Rewrote major parts of the ID cache system. Don't know
4243 whether it is better now or not but at least the API is more
4246 * Major rewrite on ID cache stuff on client because of the ID
4247 cache API changes. Added idlist.c to client.
4249 * Also major rewrite on ID cache stuff on server as well.
4250 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4251 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4252 in hand, instead they are all put into the ID cache system now.
4253 All server_idlist_* routines uses ID cache now instead of
4254 traversing its own lists (those lists does not exist anymore).
4255 SilcIDList though still exists. Also, SilcXXXEntry's are
4258 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4260 * Finally made the SKE implementation compliant to the protocol
4261 specification. All mp integers are now binary encoded as
4262 opposed being HEX encoded.
4264 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4267 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4268 functions: silc_[encode/decode]_pem. Also added function
4269 silc_encode_pem_file to PEM encode with newlines ('\n') for
4272 * SILC public keys are now encoded either PEM or binary. Same
4273 option is for private keys as well. By default private keys
4274 are binary encoded and public keys PEM encoded. Silly HEX
4275 encoding were removed.
4277 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4278 function to create fingerprints.
4280 * Fixed a bug in SHA1; does not change the original data anymore.
4282 * Partly implemented INFO command on client and server side.
4283 Fixed CLEAR command. Changes to SERVER command; show current
4284 server(s) when giving command without arguments. Added
4285 VERSION command to client.
4287 * Added check to server that unregistered connections cannot
4288 execute commands (unless it is specificly allowed).
4290 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4292 * Fixed screen refresh.
4294 * Fixed channel joining bug from client. On some circumstances
4295 client tried to join to a channel it had already joined.
4297 * Added public key verification process into client's protocol.c.
4298 The client now verifies the public key from user and saves
4299 it into ~./silc/serverkeys/ directory.
4301 Added into: clientutil.[ch]: silc_client_verify_server_key.
4303 * Changed SKE protocol's silc_ske_initiator_finish function
4304 to accept callback function that verifies the received public
4305 key. Removed old silc_ske_verify_public_key function.
4307 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4309 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4310 silc_pkcs_private_key[_data]_set.
4312 * Made the password and public authentication more cleaner in
4313 server's protocol.c.
4315 * Removed historic and obsolete protocol `channel_auth' from
4316 both client and server.
4318 * Removed wrong way of sending command status messages from
4319 server to client in server's command.c. The old way violated
4320 protocol specification.
4322 Changes to silccore/silccommand.[ch]: removed
4323 silc_command_encode_status_payload -> not needed anymore,
4324 changed silc_command_encode_payload_va to accept extra
4325 argument on variable argument list. The argument type must
4326 now be provided to the function. Also, added new function:
4327 silc_command_encode_reply_payload_va which is same as
4328 normal command_encode_payload_va except command status type
4329 is provided as extra argument.
4331 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4333 * Added ~./silc directory handling. The directory includes the
4334 public and private keys for the client.
4336 Added silc_client_check_silc_dir, silc_client_create_identifier
4337 and silc_client_load_keys.
4339 * Implemented SILC protocol compliant public key. Added public
4340 and private key saving to and loading from files.
4342 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4343 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4344 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4345 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4346 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4348 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4349 silc_pkcs_load_[public/private]_key.
4351 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Added silc_server_get_route (route.[ch]) to get connection
4354 data for the fastest route for given ID.
4356 * Implemented INVITE command on client and server. The command
4357 were re-defined in the SILC Protocol Specification and the
4358 implementation now complies with the specification.
4360 * Implemented PING command on client and server.
4362 * Implemented NAMES command on client and server. The server side
4363 supports currently only normal server not router server yet.
4364 Some changes to NAMES definition in SILC protocol specification.
4366 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4368 * Implemented LEAVE command on client and server.
4370 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4371 again. This change was made to the protocol as well. Server
4372 should not violate the protocol specification anymore.
4374 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4376 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4377 was tested. SOCKS4 was not but should work anyway.
