1 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Fixed a possible crash in silc_server_remove_clients_by_server
4 in silcd/server.c. Fixed there also some memory leaks.
6 * Fixed the silc_idlist_replace_client_id. It could replace
7 wrong key in the hash table. Affected file silcd/idlist.c.
9 * Do not check whether there are global users on the channel
10 if the channel->global_users is FALSE. Affected functions
11 silc_server_remove_from_one_channel and
12 silc_server_remove_from_channels in silcd/server.c. Also,
13 do not check if the removed client is local as we can be
14 sure that global client was not removed from the channel
15 and checking for global users is not needed.
17 * The silc_server_remove_clients_by_server now re-generates
18 the channel keys correctly for those channels that had
19 clients removed from them. Affected file silcd/server.c.
21 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
23 * Found the reason of random crashes in the server. We weren't
24 ignoring the SIGPIPE signal (which can be sent in write())
25 and it crashed the server. Affected file silcd/silcd.c.
27 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
29 * Assure that sock->user_data is not NULL in the function
30 silc_server_packet_send in silcd/packet_send.c.
32 * Disconnect the remote connection if it could not be added
33 to any ID lists in the server. The affected file is
36 * Check in silc_server_packet_send[_real/dest] that the
37 socket is not disconnecting and ignore the data if it is.
38 Affected file silcd/packet_send.c.
40 * Define inline to __inline on native WIN32 compilation.
41 Affected file includes/silcwin32.h.
43 * Added some explicit type casts for inline code since MSVC
44 require them. Affected files lib/silcutil/silcbuffer.h,
45 lib/trq/silcdlist.h and lib/trq/silclist.h.
47 * Print warning in log files from now on if the packet
48 decryption fails. Affected file silcd/server.c.
50 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
52 * Changed the `say' client operation's interface to accept
53 new `type' argument to indicate the type of the message sent
54 by the library. The application may filter the library's
55 messages according the type. The affected file is the
56 lib/silcclient/silcapi.h.
58 * Added two new functions to lib/silcclient/silcapi.h:
59 silc_client_del_client and silc_client_del_client_by_id.
60 Affected file lib/silcclient/idlist.c.
62 * Moved the clientincludes.h from includes/ to silc/ and
63 serverincludes.h from includes/ to silcd/.
65 * The modes for the CMODE and CUMODE are now passed as
66 uint32 for application with COMMAND_REPLY. The affected
67 file is lib/silcclient/command_reply.c.
69 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
71 * /WHOIS without arguments shows client's own information.
72 Affected file lib/silcclient/command.c.
74 * Changed PING to not accept any arguments. The specs
75 says that client can ping only the connected server so
76 requiring an argument is not needed. Affected file is
77 lib/silcclient/command.c.
79 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
81 * Fixed a fatal bug in private message sending and reception
82 encryption and decryption when using private message keys.
83 The implementation was incorrect and did not follow the
84 specification. It causd that some of the message were
85 lost since it did not use the sending and receiving keys
86 as the protocol suggests. This has been fixed and will cause
87 incompatibilities with older clients when sending private
88 message encrypted with private message keys. Affected files
89 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
90 and various other in Irssi SILC Client.
92 Added `responder' boolean argument to the functions
93 silc_client_add_private_message_key[_ske] to indicate when
94 the key is added as responder or initiator of the key
97 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
99 * Removed the silc_ske_check_version function and created
100 a SilcSKECheckVersion callback. Added also a function
101 silc_ske_set_callbacks that is now used to set all SKE
102 callbacks. The callback functions are not given to
103 the SKE functions anymore, but this function is used to
106 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
108 * Added `silc_version' argument to the silc_client_alloc
109 to define the version of the application for the library.
110 The library will use the version string to compare it
111 against the remote host's (usually a server) version
112 string. Affected file lib/silcclient/silcapi.h
114 * Added the KE protocol context to Key Agreement context
115 in client library so that we can abort the SKE if it
116 is in process when we get timeout. Affected file is
117 lib/silcclient/client_keyagr.c.
119 * Do not resolve the client ID forever if it returns in the
120 first time that such client does not exist. This was done
121 for example with private message. Affected file is
122 lib/silcclient/client_prvmsg.c.
124 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
126 * Do not add regex.h for WIN32. The affected file
127 includes/silcincludes.h.
129 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
130 not work yet 100%. It generates the DLL's automatically
131 when compiling with --with-win32 under cygwin.
133 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
135 * lib/contrib/regex.c is not compiled on WIN32.
137 * Added silc_net_get_socket_opt function to the
138 lib/silcutil/silcnet.h.
140 * Added includes/silcwin32.h for WIN32 specific includes
143 * Do not use ptime structure or any of the posix process
144 functions on WIN32 in lib/silccrypt/silrng.c.
146 * Added silc_gettimeofday to provide generic function
147 for struct timeval on all platforms. Added the function
148 to lib/silcutil/silcutil.h.
150 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
152 * Moved the lib/silccore/silcsockconn.[ch] to the utility
153 library as they clearly belong there. As a plus side we
154 can make the actual socket connection routines platform
157 Added also new generic function silc_socket_read and
158 silc_socket_write (that used to be silc_packet_[read/write].
159 The implementation of these are platform specific.
161 * Added WIN32 specific routines of silc_socket_[read/write]
162 to lib/silcutil/win32/silcwin32sockconn.c.
164 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
166 * Added preliminary support for native WIN32 compilation under
167 cygwin (using the -mno-cygwin option for GCC) to the
168 ./configure.in.pre. The --with-win32 now prepares the
169 compilation for native WIN32.
171 * Rewrote the SILC Scheduler interface in the file
172 lib/silcutil/silcschedule.h. The scheduler is now context
173 based and does not have anymore any global static scheduler.
174 Moved the Unix scheduler to the lib/silcutil/unix/ directory
175 and created lib/silcutil/win32 directory for WIN32 based
178 * Added Unix specific network routines to the
179 lib/silcutil/unix/silcunixnet.c and the old
180 lib/silcutil/silcnet.c includes now only generic routines.
182 Added WIN32 specific network routines to the
183 lib/silcutil/win32/silcwin32net.c.
185 * Added Unix specific utility functions from the
186 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
188 * Added WIN32 SILC Scheduler to the file
189 lib/silcutil/win32/silcwin32schedule.c. The code is of course
192 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
194 * Do not handle JOIN notify in the server if the target client
195 is not registered (idata->registered == FALSE). The affected
196 file is silcd/packet_receive.c.
198 * Update the nickrec->founder in event_cumode in the Irssi SILC
199 client. Affected file irssi/src/silc/core/silc-channels.c.
201 * Fixed the CUMODE_CHANGE notify handling in the server when
202 server and router are announcing their clients on channels.
203 Now the mode changes are saved and notified correctly. The
204 affected file is /silcd/packet_receive.c.
206 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
207 They really did not replace the cache entry in the ID Cache.
208 Now they do that. Affected file silcd/idlist.c.
210 * Fixed the KICK notify handling in the Irssi SILC client to
211 update the channel records so that the kicked client does not
212 appear to be on the channel. The affected file is
213 irssi/src/silc/core/silc-channels.c.
215 * Always update the conn->current_channel when executing command
216 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
218 * Fixed the KILL notify handling in Irssi SILC client to remove
219 the killed client on all channels.
221 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
223 * Fixed the silc_parse_command_line to remove extra spaces
224 from the start and end of the arguments. Affected file is
225 lib/silcutil/silcutil.c.
227 * Cancel and free any active protocol in the function
228 silc_server_close_connection. Affected file silcd/server.c.
230 * Cancel and free any active protocol in the function
231 silc_client_close_connction. Affected file is
232 lib/silcclient/client.c.
234 * Do not execute the KILL command for clients that are in
235 history (ie. they are not in the network). Affected file is
238 * Fixed KILL notify handling, client does not crash anymore.
239 Affected file irssi/src/silc/core/silc-channels.c.
241 * Reduced the default packet buffer size from 2048 to 1024 in
242 lib/silccore/silcpacket.c.
244 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
245 counter to the SKE context that is incresed when the SKE library
246 performs async operation outside the library. If the outside
247 process frees the SKE context and FREED status will be set
248 and the library will detect after the sync operation that the
249 libary is freed. The affected files are
250 lib/silcske/silcske[_status].[ch].
252 * Resolve the client entry information in the function
253 silc_client_channel_message to assure that NULL pointer is not
254 passed as client entry to the application. */
256 * Fixed the task timeout calculation to assure that there is
257 never negative timeouts. The affected file is
258 lib/silcutil/silcschedule.c.
260 * Fixed the channel user mode notification sending in server.
261 It was sent point-to-point to the router (or to server by router)
262 but it needs to be destined to a channel. The routines now
263 supports sending the channel user mode notifys to the channels
264 when announcing clients and channels. Affected files are
265 silcd/server.c and silcd/packet_receive.c.
267 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
268 It did not actually replace the old channel entry in the cache.
269 Affected file lib/silcclient/client_notify.c.
271 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
273 * Fixed a possible crash in silc_packet_send_prepare. It now
274 assures always that there is enough space in the buffer and
275 at the tail area of the buffer (for MAC).
277 Fixed the inbound buffer reallocation in silc_packet_read.
278 It was old code and did not handle the reallocation correctly.
281 The affected file is lib/silccore/silcpacket.c.
283 * Fixed buffer overflow in silc_parse_nickname in the file
284 lib/silcutil/silcutil.c.
286 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
288 * make install generates new server keys only if there is not
291 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
293 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
294 Added check that if the NOREPLY is set then we will not send
295 the away message. This avoids infinite loop of away messages
296 if both clients are away. The affected file is
297 lib/silcclient/client_prvmsg.c.
299 * Fixed client crash if /NICK was given without arguments.
300 Affected file lib/silcclient/command.c.
302 * Server does not send the invite list in INVITE command back
303 to the client if the list was not altered. Added this notion
304 to the protocol spec as well. Affected file silcd/command.c.
306 Fixed possible crash in INVITE command by checking the
307 value of silc_server_get_client_route command.
309 * Fixed the INVITE notify type handling. The arguments are now
310 taken in correct order and client does not crash. The affected
311 file is irssi/src/silc/core/silc-channels.c.
313 Removed the "Inviting xxx to channel" message from the
314 client library away and let the application handle it.
315 Affected file lib/silcclient/command.c. Added that message
316 to Irssi SILC client's message formats.
318 * Fixed CMODE command crash in client. It now checks the
319 amount of arguments correctly and does not crash. The affected
320 file is lib/silcclient/command.c.
322 * Do not create new channel automatically in silc_channels_join
323 but check whether the channel by that name already exists.
324 Affected file irssi/silc/core/silc-channels.c.
326 * Do not send the SERVER_SIGNOFF to router if the disconnected
327 entity was the router. Affected file silcd/server.c.
329 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
330 SILC client as it was missing from there.
332 Added the handling of the KICK notify to the Irssi SILC client
333 as it was missing. Added "you have been kicked" message to
334 Irssi SILC client's message modules formats.
336 Added the handing of the KILL notify to the Irssi SILC client
337 as it was missing. Added the kill message module formats
340 The affected file is irssi/src/silc/core/silc-channels.c.
342 * The router did not save the channel mode the server announced.
343 Affected file silcd/packet_receive.c.
345 * Fixed a possible crash in INFO command in server. If the
346 server did not provide the server info it crashed. Affected
347 file silcd/command.c.
349 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
351 * Fixed the GETKEY command in the server to check also the
352 global list. Otherwise the GETKEY would not work correctly
353 in normal SILC server. Affected file silcd/command.c.
355 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
357 * Fixed GETKEY crash, it crashed if the command did not succseed.
359 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
361 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
362 is now real and not just an macro interface to GMP.
364 Removed the entire GMP from the source tree and imported new
365 NSS MPI library instead. Reason for removing GMP is that it is
366 extremely large and compiles extremely slow. The NSS MPI
367 is only a few files and compiles in less than 10 seconds.
368 The speed is also about the same as GMP. The MPI is imported
371 If the system has GMP installed we will still use the GMP.
372 If it is not then the NSS MPI will be compiled.
374 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
376 * Merged a long nickname (127 characters long) crash bugfix from
377 Irssi CVS tree. Affected file irssi/src/core/misc.c.
379 * Merged a freed memory reference bugfix from Irssi CVS tree.
380 Affected file irssi/src/core/commands.c.
382 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
384 * Added the server's public key sving and verification to the
385 server when performing the SKE. This was missing and the
386 remote server's (or router's) public key was accepted without
387 checking whether we have it previously or trust it at all.
388 Affected file silcd/protocol.c.
390 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
392 * Check in the silc_server_timeout_remote if protocol is active
393 and make sure that the protocol's final callback is called so
394 that all memory if freed. Affected file silcd/server.c.
396 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
398 * silc_server_whois_send_reply crashed the server if the nickname
399 was 127 characters long. Affected file silcd/command.c.
401 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
403 * Added sanity check to the silc_server_new_client. If the hostname
404 is provided inside username then check that the provided hostname
405 really is the same as the resolved one. If the hostname was not
406 resolved then check it from the public key. Affected file is
407 silcd/packet_receive.c.
409 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
410 if the server disconnected us and the connection is not valid
411 anymore. Affected file irssi/src/silc/core/silc-channels.c.
413 * Moved the silc_client_[chmode|chumode|chumode_char] away from
414 the library to the lib/silcutil/silcutil.[ch].
416 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
418 * Close log file after open. Affected file
419 lib/silcutil/silclog.c.
421 * Check whether sock == NULL in silc_client_send_packet and return
422 if it is. Affected file lib/silcclient/silcclient.c.
424 * Check rec->entry == NULL in the Irssi SILC Client before
425 sending the channel message. Affecte file is
426 irssi/src/silc/core/silc-servers.c.
428 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
430 * Merged a splitted window bugfix from Irssi CVS tree. The
431 affected file is irssi/src/fe-text/textbuffer-view.c.
433 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
434 It did not print nickname.
436 * Improved the distributions system a bit.
438 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
440 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
441 irssi/src/fe-text/gui-window.c.
443 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
444 to in-active server. The affected file is
445 irssi/src/silc/core/client_ops.c.
447 * Resolve the client in USERS command reply if the entry does
448 not have username resolved. The affected file is
449 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
450 command to WHOIS command to really resolve stuff. The USERS
451 is not used any more in any critical section so WHOIS can
452 be used even though it might be slower than IDENTIFY.
454 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
457 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
459 * Changed the protocol API a bit more consistent in the
460 lib/silccore/silcprotocol.[ch].
462 * Changed the following headers to ROBODoc format:
464 lib/silccore/silcpayload.h
465 lib/silccore/silcprotocol.h
466 lib/silccore/silcsockconn.h
468 All core library headers are now formatted.
470 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
472 * Fixed a bug in Irssi SILC client; do not show that you are
473 server/router operator if you really are not. Affected file is
474 irssi/src/silc/core/client_ops.c.
476 * Renamed silc_command_free_payload to silc_command_payload_free.
477 Affected file lib/silccore/silccommand.h
479 * Added silcmath.h to include the prototoypes of various routines
480 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
483 * Changed the following headers to ROBODoc format:
485 lib/silccore/silcchannel.h
486 lib/silccore/silccommand.h
487 lib/silccore/silcid.h
488 lib/silccore/silcidcache.h
489 lib/silccore/silcmode.h
490 lib/silccore/silcnotify.h
491 lib/silccore/silcpacket.h
492 lib/silcmath/silcmath.h
494 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
496 * Added checking to the server code not to start the server if
497 ciphers and stuff are not configured properly. Affected files
498 silcd/serverconfig.[h] and silcd/server.c.
500 * Changed the layout of the header files of the public interfaces
501 in the SILC libraries. The new layout supports ROBODoc
502 documentation tool (and some others) so that it is easy to create
503 a library reference manual. All the other headers and source
504 code must still follow the CodingStyle document. Also source
505 code must not include these ROBODoc stuffs, only the headers.
506 Furthermore, all public interface headers must now be named
507 by using `silc' prefix, example: silcapi.h, silccipher.h.
508 Some files were renamed due to this. All the other headers
509 must not be used as public interfaces. I will update the
510 CodingStyle document later. Changed following headers, so far:
512 lib/silcclient/silcapi.h
513 lib/silccore/silcauth.h
514 lib/silccore/silcprivate.h
515 lib/silccrypt/silcdh.h
517 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
521 * Removed silc_client_packet_send_flush from the client library
522 as it is not needed. Affected file lib/silcclient/client.[ch].
524 * Added printing of message of unresolved authentication method
525 to the Irssi SILC client. Added it to the module formats.
526 Removed the same message from the client library.
528 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
530 * Added new distribution feature, DISTLABEL. Every distribution
531 can define own preprocessor label that can be used in the
532 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
533 file distributions, acconfig.h.pre and prepare.
535 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
537 * Added Makefile.defines_int to include the actual definitions
538 for Makefile.defines.in. Tested the new distribution system,
539 created distributions and tested installation.
541 * Added AWAY message printing to the Irssi SILC client. Added
542 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
544 * Added SCONNECT command to call the SILC's CONNECT command.
545 Cannot use CONNECT directly since Irssi uses that internally.
546 Affected file irssi/src/silc/core/silc-servers.c.
548 Added ACTION local command. It is same as ME command but takes
549 the channel as mandatory argument.
551 Rewrote some of the Irssi's help files to suite for SILC
554 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
556 * Added Makefile.defines[.in] that should for now on be included
557 in all Makefile.am file in the source tree. That file includes
558 all common compilation definitions for SILC source tree.
560 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
562 * Minor changes to the ./prepare script to change the package
563 name according the distribution name to the configure.in.
565 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
567 * Created new distribution system. Added file `distributions'
568 that defines all the distributions that can be created out of
569 the SILC source tree. The ./prepare script now reads that
570 file to determine how to prepare the distributions. The
571 first argument to the ./prepare is the name of the distribution
572 and second is the version of the distribution. If given
573 without arguments it creates the default (toolkit) distribution
574 with the default version (defined in ./prepare).
576 All Makefile.am files that are subject to the distributions
577 are now named as Makefile.am.pre. These are ./Makefile.am
578 and lib/Makefile.am. Others may be changed later.
580 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
582 * Added invite list, ban list, some key management and connection
583 error message printing to module formats in the Irssi SILC client.
585 * Added new silc_client_set_away_message to set the away message
586 that is back to the person who sent private message. The
587 affected file lib/silcclient/silcapi.h and the
588 lib/silcclient/client_prvmsg.c.
590 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
592 * Fixed the private message sending in the Irssi SILC client,
593 added local command KEY to the Irssi SILC client.
595 Added key management and key agreement message formats to the
596 irssi/src/fe-common/silc/module-formats.[ch].
598 Added USERS (alias WHO) printing, server/router operator
599 indication and LIST command printing to the module formats.
601 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
603 * Fixed channel joining notify handling, cumode notify handling
604 from Irssi SILC client.
606 * Added SILC specific module-formats to the Irssi SILC client so
607 that SILC specific message hilighting, colors etc is possible.
608 Affected file irssi/src/fe-common/silc/module-formats.[ch].
610 Added channel mode, channel user mode, actions, notices,
611 whois and whowas printing to the the module-formats.c.
613 * Fixed a bug in channel deletion in the server. The channel
614 is not left to the cache even if the channel founder auth mode
615 is set when there are no users anymore on the channel. Affected
618 * The silc_net_localhost now resolves the entire hostname including
619 the domain name. Affected file lib/silcutil/silcnet.c.
621 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
623 * Changed the ask_passphrase client operation to be ascynchronous.
624 It has now a completion callback and a context that the
625 application must call after it has got the passphrase from
626 the user. Affected files lib/silcclient/silcapi.h,
627 lib/silcclient/protocol.c, lib/silcclient/command.c and
630 Added SilcAskPassphrase callback that the application calls
631 to deliver the passphrase to the library.
633 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
634 The public key verification and especially a certificate
635 verification is asynchronous procedure.
637 Added new SILC_SKE_STATUS_PENDING status to indicate the
638 request is pending and a callback will be called to finalize
641 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
642 indicate that remote end did not send its public key (or
643 certificate), even though we require it. Added check for this
644 condition in the SKE. This was a security bug, now fixed.
646 Defined new SilcSKEVerifyCbCompletion callback that is called
647 when the verification process is completed.
649 The affected files lib/silcske/silcske_status.h and
650 lib/silcske/silcske.[ch].
652 * Changed the verify_public_key client operation to be async
653 as well. Defined SilcVerifyPublicKey callback that is used to
654 indicate the success of the public key verification process.
656 Changed the server and client to use the new async client
659 * Changed the Irssi SILC client's internal scheduler to be called
660 twice as many times as it used to be. As a result the client
661 should be a bit faster now. Affected file is
662 irssi/src/silc/core/silc-core.c.
664 * Added support to Irssi SILC client of asynchronous public key
665 verification and passphrase inquiry. Affected file is
666 irssi/src/silc/core/silc-core.c.
668 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
670 * Do not say "You have left channel %s" in client library.
671 Moved it to the application. Affected files are
672 lib/silcclient/command.c and silc/client_ops.c.
674 * Fixed silc_client_get_clients. Command context was not
675 duplicated and was freed memory in the callback. Affected
676 file lib/silcclient/idlist.c.
678 * Do not say "you are now talking..." on JOIN command in the
679 client library. The appliation must handle it.
681 * Do not say ".. changed topic to" in command reply in the
682 client libary. The application must handle it.
684 * Fixed TOPIC command sending in the client library.
686 * Fixed a memory leak in silc_client_command_free in the file
687 lib/silcclient/command.c.
689 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
691 * Imported a modified version of Irssi client to the source tree.
692 The Irssi will be used to create a new client called
693 Irssi SILC. Imported to irssi/.
695 Added silc_core_init_finish function to the Irssi. Affected
696 file irssi/configure.in.
698 A lot changes in the Makefile.ams around the irssi tree.
700 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
702 * Do not rehash if the new size is same as the old size of the
703 hash table, in the silc_hash_table_rehash*. The affected file
704 lib/silcutil/silchashtable.c.
706 * Replaced hash_table_del_by_context calls from the server
707 (when channel->user_list and client->channels) to the
708 hash_table_del as it is sufficient and faster.
710 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
712 * Added silc_hash_table_list, silc_hash_table_get and the
713 SilcHashTableList structure to provide an alternative way to
714 traverse the hash table. The affected files are
715 lib/silcutil/silchashtable.[ch].
717 * Changed the server's idlist routines to use the hash table
718 routines to optimize the code.
720 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Replaced the client entry's `channel' list and channel entry's
723 `user_list' list to hash tables for optimized lookup. Changed
724 the code to use the hash table interface around the code.
725 Affected file lib/silcd/idlist.[ch].
727 * Added `auto_rehash' boolean argument to the function
728 silc_hash_table_alloc to indicate whether the hash table should
729 auto-rehash when it thinks is appropriate time. It will
730 increase the hash table size if the there is twice as much
731 entries in the table than the size of the table, and will
732 decrease the size if there are twice as less entries than
733 the size of the table.
735 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
737 * Fixed silc_xxx_get_supported to not crash at some circumstances.
739 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
741 * silc_idcache_purge_by_context deletes the entry now by context
742 as it is supposed to do. Affected file lib/silccore/idcache.c.
744 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
745 client is not anymore valid (WHOWAS givens the info) and not
746 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
748 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
750 * Removed the `data' and `data_len' arguments from the ID Cache
751 interfaces and added `name' argument. ID Cache does not handle
752 anymore the binary data only a names associated with given ID.
754 * When hashing a Client ID with silc_hash_id the entire ID is
755 not hashed anymore, instead only the hash of the Client ID is
756 hashed. This way we can access the Client ID from the cache
757 with Client ID but with the hash of the ID (which is a hash of
758 the nickname) as well without any difference in performance.
760 Added also silc_idcache_find_by_id_one_ext to do one on one
761 searching when we have the actual ID. Added also function
762 silc_hash_client_id_compare. The affected files are
763 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
765 * When hashing the name associated with a ID it is always done
766 in lowercase. This way we can access the cache without worrying
767 about case-sensitivity, even though, for example nicknames are
770 * Fixed a bug in server with channel message sending. It put
771 wrong ID type as destination ID. The affected file
774 * silc_idcache_del_by_context now deletes from all hash tables
775 by context. Affected file lib/silccore/idcache.c.
777 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
779 * Changed the client library to use the new ID Cache interface.
780 Changes around the source tree.
782 * Added silc_hash_table_rehash_ext to rehash with specific
783 hash function. Affected file lib/silcutil/silchashtable.[ch].
785 * Added silc_hash_string_compare to compare two strings in the
786 hash table. Affected file lib/silcutil/silcutil.[ch].
788 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
790 * Added new function silc_idcache_del_by_context into the
791 lib/silccore/idcache.[ch].
793 * Changed the server's ID list routines to use the new ID Cache
794 interface. Changes around the source tree.
796 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
798 * Added silc_hash_table_del[_by_context]_ext functions in to the
799 lib/silcutil/silchashtable.[ch].
801 Removed silc_hash_table_find_all* routines and added new
802 silc_hash_table_find_foreach to replace them.
804 Added silc_hash_table_replace_ext function as extended
805 replacing function. Separated the simple hash table interface
806 from the extended hash table interface in the file
807 lib/silcutil/silchashtable.h.
809 * Fixed minor bugs and changed it to use some of the new
810 hash table functions in lib/silccore/idcache.c
812 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
814 * Added new function silc_hash_table_find_all to return all keys
815 in the hash table by the specified key. As the hash table is
816 collision resistant it also makes it possible to have several
817 duplicate keys in the hash table. This function may be used to
818 find all of the keys from the hash.
820 Added user_context arguments to the SilcHashFunction,
821 SilcHashCompare and SilcHashDestructor to deliver user specified
824 Added new fuctions silc_hash_table_find[_all]_ext to do
825 extended lookup with specified hash and compare functions and
826 specified user contexts.
828 Added new function silc_hash_table_add_ext to add the key
829 with specified hash function and user context.
831 Added new function silc_hash_table_foreach to traverse all
832 entrys in the hash table. Added SilcHashForeach callback
835 Added new function silc_hash_table_del_by_context to delete
836 the entry only if the context associated with the key matches.
838 Affected files are lib/silcutil/silchashtable.[ch].
840 * Removed silc_hash_[server/client/channel]_id and added just
841 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
842 silc_hash_id_compare to compare two ID's using as the hash table
843 comparison function. Added also silc_hash_data to hash
844 binary data and silc_hash_data_compare to compare it.
846 * Removed silc_idlist_find_client_by_hash as it is not needed
847 anymore. Affected file silcd/idlist.[ch].
849 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
850 to use internally the SilcHashTable. The new ID Cache is a lot
851 faster than the old one. Some of the ID Cache interface was also
852 rewritten and obsolete and stupid functions were removed.
854 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
856 * Added entry_count field to the SilcHashTable to keep the number
857 of the entries in the table. Implemented the function
858 silc_hash_table_rehash. Added new function
859 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
861 Fixed a minor bug in silc_hash_table_free.
863 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
864 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
865 into the lib/silcutil/silcutil.[ch].
867 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
869 * Implemented a collision resistant hash table into the
870 lib/silcutil/silchashtable[ch]. See the header and the source
871 for the SilcHashTable API.
873 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
875 * Merged dotconf version 1.0.2 into lib/dotconf.
877 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
879 * Do not compile anything in lib/silcsim/* if the SIM support
880 is not enabled. The tree should now compile without problems
883 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
885 * Compiled the SILC under cygwin. Compiled and tested briefly
886 without problems. More tests needed. The SIMs didn't compile
889 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
891 * Fixed possible crash in silc_get_username in the
892 lib/silcutil/silcutil.c.
894 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
896 * Fixed a va_arg in silc/client_ops.c.
898 * Oops, RC5 routines were named AES and caused some problems
899 when not using SIM's. Affected file lib/silccrypt/rc5.c.
901 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
903 * Added new SilcIDIP structure into the lib/silccore/id.h and
904 replaced the old `ip' fields from all SILC ID's to that type.
905 This is a step towards IPv6 support.
907 The silc_id_get_len takes now the ID as an extra argument.
908 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
909 both IPv4 and IPv6 based ID's.
911 The affected files are lib/silccore/id.[ch] and other files
912 around the tree using these routines.
914 * Removed the ID length arguments in server from various
915 silc_server_send_notify_* routines -> they are not needed
918 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
920 * Fixed memory leak in silc_encode_pem_file in the file
921 lib/silcutil/silcutil.c.
923 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
925 * Check minor version as well in the SKE. Affected files are
926 silcd/protocol.c and lib/silcclient/protocol.c.
928 * Added --identifier option to the server so that an identifier
929 can be when creating the public key for the server. Affected
930 file is silcd/silcd.c.
932 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
933 lib/silccrypt/silcpkcs.c.
935 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
937 * Register default ciphers and stuff when using -C option with
938 the server. Affected file sildc/silcd.c.
940 * Put back the servers public key filename format, it is better
941 than the new one. For now, the client keys are saved with the
942 new filename format. The affected file silc/client_ops.c.
944 * Implemented the Cipher API for the rest of the ciphers that
945 did not implement it or implemented it the wrong way.
947 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
949 * Register default ciphers and stuff when using the -S option
950 in the client. Affected file silc/silc.c. Same also when
951 creating new key pair with -C option.
953 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
955 * Fixed the silc_verify_public_key client operation function to
956 save the public keys differently. The fingerprint is now
957 used as filename and not the hostname. This way also the
958 client keys are saved uniquely and not with hostnames. The
959 affected file is silc/client_ops.c.
961 * Trimmed the silc_hash_fingerprint function to remove extra
962 whitespaces from the end of the fingerprint. The affected
963 file is lib/silccrypt/silchash.c.
967 * Added silc_cipher_register_default function to register all
968 default ciphers. It can be used when configuration files
969 does not exist and the application does not want any specific
970 ciphers in any specific order.
972 The SilcDList is now used as silc_cipher_list dynamically
973 allocated cipher list. Removed the static list all together
974 and now all ciphers must be allocated to the dynamic list.
975 The silc_cipher_alloc routine was changed to check only the
978 All silc_cipher_* routines that used to return int returns
981 The affected files lib/silccrypt/silccrypt.[ch].
983 * The same thing was done to silc_hash_* as for silc_cipher_*
984 routines. Affected files lib/silccrypt/silchash.[ch].
986 * The same thing was done to silc_pkcs_* as for silc_cipher_*
987 routines. Affected files lib/silccrypt/silcpkcs.[ch].
988 Added also silc_pkcs_[un]register[_default] functions.
989 Removed the data_context from the PKCS API.
991 * Added silc_hmac_register_default function to register default
992 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
993 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
994 to unregister all hmacs at once.
996 * Register the default ciphers, hash functions, PKCSs and HMACs
997 if client's configuration file does not exist. The affected
1000 * The client did not load the hash functions from the SIM
1001 modules at all. Added support for this. Affected file is
1002 silc/clientconfig.c.
1004 * When decoding public key with silc_pkcs_public_key_decode, check
1005 the supported algorithm only if PKCS are registered. Affected
1006 file lib/silccrypt/silcpkcs.c. The same was done with the
1007 silc_pkcs_private_key_decode.
1009 * Fixed the SILC List routines to keep the list always in order.
1010 It used to change the list's order when traversing the list but
1011 not it preserves the order. Affected file lib/trq/silclist.h.
1013 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1015 * Added the client library to use the SilcSocketConnection's
1016 reference counter (by silc_socket_dup) to prevent the bug that
1017 the socket object may be freed underneath async operation.
1019 * The name resolv library checking fixes in the configure.in.pre.
1022 * Created new version of the protocol drafts for future
1023 development. The -03 drafts are the ones that will be changed
1024 in the trunk now and the -02 will remain as they are.
1026 * Send list of CUMODE notifys to the router when announcing
1027 the channel users to the router. Affected file silcd/server.c.
1028 If the router receiving channel founder CUMODE for a channel
1029 that already has channel founder it will send CUMODE notify
1030 to the sender to remove the channel founder rights from the
1031 announced client. Affected file silcd/packet_receive.c.
1033 * The CUMODE notify may now use Server ID as well as the entity
1034 who changes the mode. Updated protocool specs.
1036 * Updated INSTALL and README files.
1038 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1040 * New web pages in the http://silc.pspt.fi. The pages was
1045 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1047 * Implemented the [DenyConnectin] config section in the server.
1048 Added silc_server_config_denied_conn to check whether incoming
1049 connection is denied. Affected file silcd/serverconfig.[ch].
1051 * Do not check the ports when checking the incoming configuration
1052 data if the port is 0, meaning any. Affected file is
1053 silcd/serverconfig.c.
1055 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1057 * Fixed buffer overflow in silc_string_compare in the file
1058 lib/silcutil/silcutil.c.
1060 * Fixed double free in silc_server_command_leave in the file
1063 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1065 * Fixed the version checking in the server. Affected file is
1068 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1070 * Fixed the configuration data fetching when accepting new
1071 connections in the server. Affected file silcd/server.c.
1073 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1075 * Added `sender_entry' argument to the function
1076 silc_server_packet_relay_to_channel so that we can check
1077 whether some destination actually belongs to the same route
1078 the sender belongs (ie, we must not resend the packet to the
1079 sender). Affected file silcd/packet_send.[ch].
1081 * Added `servername' field to the SilcClientEntry in the server
1082 to hold the name of the server where client is from. Affected
1083 file is silcd/idlist.h.
1085 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1087 * Moved the channel message encrypting in the router betwen
1088 router connections from silc_server_channel_message to the
1089 silc_server_packet_relay_to_channel since we want to check
1090 whether we have anybody channel before encrypting anything.
1091 Affected files silcd/packet_[receive/send].c.
1093 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1095 * Fixed the [AdminConnection] server config section to support
1096 multiple entries. Affected file silcd/serverconfig.c.
1098 * Added support into the server to check the validity of the
1099 incoming connection before executing any KE or authentication
1102 * The connection configuration is now saved to the KE and
1103 connection auth protocol contexts and not fetched anymore in
1104 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1106 * The local hosts listenning address and port is also resolved
1107 now when starting the server. We want to have the socket object
1108 to include the real address and port for the listener. Added
1109 new function silc_net_check_local_by_sock into the files
1110 lib/silcutil/silcnet.[ch].
1112 * Fixed a broadcast bug in server -> do not broadcast if we
1115 * Fixed a routing bug. Do not route broadcast packets ever.
1116 Broadcast packets must be processed always and not routed since
1117 they may be destined to some other host than yourself and thus
1118 would get routed without no good reason. Affected file is
1121 * Added function silc_server_config_is_primary_route to check
1122 whether primary router connection has been configured (a router
1123 configuration that we are initiating). If there is not, we
1124 will assume that there is only two routers in the SILC network
1125 and we will use the incoming router connection as our primary
1126 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1128 * Changed the order of the broadcasting. Broadcast _after_ the
1129 packet has been processed not before. Affected file is
1132 * Fixed a [ClientConnection] parsing bug. The port was never
1133 parsed correctly thus resulting to port 0. Affected file
1134 silcd/serverconfig.c.
1136 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1137 argument and did not set the broadcast packet flag. Affected
1138 file silcd/packet_send.c. Fixed same bug in the function
1139 silc_server_send_notify as well.
1141 * If we receive NEW_ID packet for our own ID in the server, ignore
1144 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1148 * Removed the nickname from the Private Message Payload.
1149 Updated the code and the protocol specs.
1151 * Updated protocol specs for submitting to the IETF.
1153 * Tweaked the Random Number Generator a bit. Affected file
1154 lib/silccrypt/silcrng.c. Exported a new function
1155 silc_rng_[global]_add_noise which can be used to add more
1158 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1160 * Do not parse packets with different timeout when protocol
1161 is active -> may cause problem with rekey. Affected file
1164 * When server receives signoff notify it must not create
1165 new channel key if the client is on any channels since the
1166 sender of the signoff notify will create it.
1168 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1170 * Added printing of error messages during SKE protocol from the
1171 failure packet sent by server during SKE. Affected file
1174 * Removed the client's failure_callback handling with timeout
1175 and handle it immediately when received.
1177 * The SKE library returned wrong type in SUCCESS and FAILURE
1178 packets. They must be 32 bit MSB not 16 bit MSB.
1180 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * Ok, rewrote the logic of the re-key and now it seems to work.
1183 I tested it on high traffic with frequent re-keys without
1184 problems. Added hmac_receive (and renamed hmac to hmac_send)
1185 in SilcClientConnection in lib/silcclient/client.h and
1186 in SilcIDListData in silcd/idlist.h. Also, removed the
1187 SilcPacketParserContext's cipher and hmac fields as they are
1188 not needed anymore and actually caused some problems when
1189 the ciphers and hmac's changed underneath the packet parser.
1191 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1193 * If re-key protocol is active then process the incoming packets
1194 synchronously since we must assure that icoming packets encrypted
1195 with the old key is processed before the new keys is set to
1196 use. This is true other packets than for REKEY packets.
1197 Affected file silcd/server.c. The same was done to client library
1198 as well, affected file lib/silcclient/client.c.
1200 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1202 * Fixed bug in client and server to accept the force send if
1203 the packet is send from silc_[server/client]_packet_process
1204 function. Otherwise the packets are never delivered, oops.
1206 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1208 * Disable force sending of packets when REKEY protocol is active.
1209 We must assure that no packet is sent directly when rekey is
1210 performed. All packets must be sent through packet queue.
1211 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
1212 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
1213 function is silc_[server/client]_packet_send_real to check
1216 * Replaced the SIM paths from example config files to
1217 /usr/local/modules. Also, make install creates now
1218 /usr/local/silc/logs directory to hold all the SILC server
1221 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1223 * Made the configure.in.pre work on Solaris. Patch by salo.
1225 * Made all ciphers compatible with non-x86 machines. Defined
1226 CBC mode macros into lib/silccrypt/ciphers_def.h.
1228 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1230 * Fixed the make install.
1232 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1234 * When MAC computation fails the silc_packet_decrypt returned 0
1235 even though it was supposed to return -1. Fixed this. The
1236 affected file is lib/silccore/silcpacket.c.
1238 * Do not replace the config files in /etc/silc (in make install)
1239 if they already exist. Affected file ./Makefile.am.
1241 * Do not send re-key packets immediately but through packet queue.
1242 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
1244 * Changed silc_net_check_host_by_sock to return FALSE if the
1245 IP/DNS could not be resolved. Though, it returns the IP address
1246 now even if it could not resolve it (but returns also FALSE).
1247 Affected file lib/silcutil/silcnet.[ch].
1249 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1251 * Added silc_pkcs_decode_identifier to decode the public key's
1252 identifier. Affected file lib/silccrypt/silpkcs.[ch].
1253 Added also silc_pkcs_free_identifier. Added also new context
1254 SilcPublicKeyIdentifier.
1256 * Added -S option to the silc client. It is used to dump the
1257 contents of the specified public key file.
1259 * Changed the PKCS api to return the public key length when
1260 setting the public key.
1262 * Fixed a fatal bug in the public and private key file loading.
1263 Affected file lib/silccrypt/silcpkcs.c.
1265 * Execute the packet parsing for client with zero (0) timeout
1266 if the protocol is active. Affected file silcd/server.c.
1268 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1270 * Made the key generation options to the silcd program. Added
1271 -C option, equivalent to client's option.
1273 * Added new [ServerKeys] config section to the server. It
1274 configures the server's public and private key.
1276 * Defined generic Public Key Payload into the protocol
1277 specification to send specific type of public keys and
1280 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
1281 public key or certificate.
1283 * Implemented the GETKEY command to the server and to the
1284 client library and on user interface.
1286 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1288 * Made preliminary `make install' work.
1290 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1292 * Added SilcServerRekey context into silcd/idlist.h.
1294 * Added the PFS support as defined in the specification to the
1295 SKE protocol. Affected files lib/silcske/*.c.
1297 * Added `ske_group' field to the SilcServerRekey context to hold
1298 the number of the SKE group that is used with PFS in re-key.
1299 Affected file silcd/idlist.h.
1301 * Added PFS re-key support to the server. Affected file is
1304 * Added silc_protocol_cancel to cancel execution of the next
1305 state of the protocol. Affected file is
1306 lib/silccore/silcprotocol.[ch].
1308 * Added the re-key support with and without PFS to the client
1309 library. Re-key is performed once in an hour, by default.
1311 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
1312 Added silc_client_rekey_callback and silc_client_rekey_final.
1313 Affected files are lib/silcclient/protocol.[ch] and
1314 lib/silcclient/client.[ch].
1316 * Removed the `hmac_key' and `hmac_key_len' fields from the
1317 SilcClientConnection structure; not needed. Affected file is
1318 lib/silcclient/client.h.
1322 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1324 * Do not ask whether user wants to use the negotiated private key
1325 for private messages, just use it. Affected file is
1326 silc/local_command.c.
1328 * Added `send_enc_key' and `enc_key_len' fields to the
1329 SilcIDListData structure since they are needed in the re-key
1330 phase. Affected file is silcd/idlist.[ch].
1332 * Implemented the simple re-key protocol into the server.
1333 Affected files silcd/server.c and silcd/protocol.[ch]. The
1334 re-key will be performed once in an hour, by default.
1336 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
1337 Added silc_server_rekey, silc_server_rekey_callback and
1338 silc_server_rekey_final.
1340 * Removed Tunneled flag from the protocol. Updated the code
1341 and the specifications.
1343 * Adde `pfs' field to the SilcIDListData to indicate whether
1344 the PFS is to be performed in the re-key. Affected file is
1347 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1349 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
1350 int64 of at least the xintXX size. If void * is less that 4
1351 bytes uint32 * will be used. Defined bool as boolean.
1353 * Changed _ALL_ unsigned long and unsigned int to uint32,
1354 unsgined short to uint16 in the source tree.
1356 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
1357 not handle clients that has entry->data.registered == FALSE.
1358 They are not in the network anymore. Affected file is
1361 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1363 * Implemented the sending of the SERVER_SIGNOFF notify in the
1364 server. Affected file is silcd/server.c.
1366 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
1367 Added also silc_notify_payload_encode_args into the
1368 lib/silccore/silcnotify.[ch].
1370 * Implemented ther SERVER_SIGNOFF notify handling in the server.
1371 Affected file silcd/packet_receive.c.
1373 * Implemented the SERVER_SIGNOFF notify handling in the client
1374 library. Affected file lib/silcclient/client_notify.c. Also,
1375 implemnted the printing of the SERVER_SIGNOFF info to the
1376 application. Affected file silc/client_ops.c.
1378 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
1379 if the deleting was successful. Affected file silcd/idlist.[ch].
1381 * Added support for public key authentication in the connection
1382 authentication protocol in the client library. Affected file
1383 lib/silcclient/protocol.c.
1385 * Changed the server's silc_idlist_get_clients_by_* interface
1386 to support already allocated array so that new entries may be
1387 added to pre-allocated array. Affected file silcd/idlist.[ch].
1388 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
1389 and command replies.
1391 * All command reply functions in the server now calls the
1392 pending command callback even if error occured. This way the
1393 error will be delivered to the client as well. Affected files
1394 silcd/command.c and silcd/command_reply.c.
1396 * Fixed INFO command to return local server's info if no server
1397 was provided. Affected file lib/silcclient/command.c.
1399 * Removed RESTART command for good. Updated the code and the
1402 * Rewrote parts of the task system. It is a bit simpler now.
1403 Removed unsued task priorities. The affected files are
1404 lib/silcutil/silctask.[ch].
1406 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1408 * Moved the USERS printing from the library to the application.
1409 Affected files lib/silcclient/command.c and silc/client_ops.c.
1411 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1415 * Added channel key re-key support. The re-key is perfomed
1416 only by the router and is done once in an hour. Added `rekey'
1417 field to the SilcChannelEntry in the server. Affected files
1418 silcd/server.c and silcd/idlist.h.
1420 * Added silc_task_unregister_by_context into the file
1421 lib/silcutil/silctask.[ch].
1423 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1425 * Added SILC_UMODE_GONE mode to indicate when the client is not
1426 present in the SILC network. Added also support to the local
1427 command AWAY that will set this mode. Added support of showing
1428 "xxx is gone" in WHOIS command. The USERS command shows the
1429 gone status as well.
1431 * Fixed setting server and router operator privileges in the
1432 server's UMODE command. Affected file silcd/command.c.
1434 * Merged the SKE KE1 and KE2 payloads into one payload. The
1435 new KE payload is equivalent to the old KE2 payload.
1437 Cleaned up the SKE Start Payload parsing. It now uses the
1438 simple buffer unformatting to do the parsing. A lot faster
1441 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
1442 to the SKE that is used to indicate whether both of the SKE
1443 parties should perform authentication. By default only the
1444 responder performs authentication. By setting this flag also
1445 the initiator must do authentication. By default it is unset
1446 since in normal SKE case, client to server connection, only
1447 the responder should do authentication. When doing SKE between
1448 two clients both should perform authentication. Updated the
1449 code and the protocol specs.
1451 * A little fix to IDENTIFY command in the server. Search the
1452 client first by hash not nickname. Affected file is
1455 * Fixed the silc_client_close_connection to support closing
1456 the client to client connections wihtout deleting too much
1457 data. Affected file lib/silcclient/client.c.
1459 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
1460 are received if protocol used to be active but is not anymore
1461 the application would crash due to NULL pointer dereference.
1462 Affected files silcd/server.c and lib/silcclient/client.c.
1464 * Added `hash' field to the SilcClientConnection to include
1465 the hash function negotiated in the SKE protocol.
1467 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
1468 to set the channel founder authentication data. A client can
1469 claim the founder rights later by providing the authentication
1470 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
1471 This way the channel founder can regain the channel founder
1472 privileges even it is left the channel. This works only on
1473 local server and the client must be connected to the same
1474 server to be able to regain the founder rights. Updated the
1475 protocol specs accordingly.
1477 Added support to the CMODE command in the client to set the
1478 founder auth data. Read the README to see how to set it.
1480 Added support to the CUMODE command to claim the founder
1481 rights. Read the README to see how to do it.
1483 Added support for the founder authentication to the Channel
1484 Entry in the server. Affected file silcd/idlist.h.
1486 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
1487 server's CMODE command. Affected file silcd/command.c.
1489 * Added the following new functions into lib/silccore/silcauth.[ch]:
1490 silc_auth_get_method and silc_auth_get_data.
1492 * The server now saves the remote hosts public key to the
1493 SilcIDListData pointer. Affected file silcd/protocol.c.
1495 * The normal server now does not remove the channel entry from
1496 the cache if the founder authentication data is set. It used
1497 to remove it if the founder was the last one on the channel on
1498 the server and left the channel. The auth data is saved and
1499 if the channel is re-joined later the old entry is used with
1500 the old auth data. Affected files silcd/command_reply.c and
1503 * Removed the `pkcs' field from the SilcIDListData structure
1504 in the server; it is not used. Affected file silcd/idlist.h.
1506 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1508 * Fixed packet processing on slow links. Partial packets were
1509 never re-processed because the incoming data buffer was cleared
1510 by the application. Application must not directly clear the
1511 sock->inbuf, the packet processing routines handle it. Fixed
1512 this in client library and in server.
1514 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1516 * Fixed the WHOIS and IDENTIFY send reply function to really
1517 check whether to send list or just one entry. Affected file
1520 * Cleaned up the LEAVE command's channel key distribution. The
1521 affected file silcd/command.c.
1523 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
1524 can enforce the channel mode as well. In that case the ID
1525 includes the ID of the server. The code now enforces the
1526 mode change if the router have different mode than the server.
1528 * The notify client operation with CMODE_CHANGE notify can now
1529 return NULL client_entry pointer if the CMODE was not changed
1530 by client. Application must check for this.
1532 * Added <Server ID> argument to INFO command to support server
1533 info fetching by Server ID.
1535 * Added silc_server_announce_get_channel_users to get assembled
1536 packets of channel users of the specified channel. Affected
1537 file silcd/server.[ch].
1539 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
1540 was freed underneath the ID Cache.
1542 * Re-announce clients when the server received CHANNEL_CHANGE
1543 notify from the router. Affected file silcd/packet_send.c.
1545 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1547 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
1548 crashed since it did not handle the fact that there is no cipher
1549 called "3" and didn't check the error condition. Now fixed.
1551 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
1552 flag. It can be used to send message requests.
1554 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1556 * Implemented the RESTART command in the client.
1558 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
1559 notice type messages. Added notice printing to the user
1562 * The channel keys are not re-generated if the channel's mode
1563 is PRIVKEY, ie private key on the channel exists. Affected
1564 files silcd/server.c and silcd/command.c.
1566 * Fixed a little bug in channel message delivery when channel
1567 private keys are set in the server. Affected file is
1568 silcd/packet_send.c.
1570 * Changed the setting on channel->on_channel = TRUE from the
1571 silc_client_save_channel_key to the JOIN command reply. The
1572 key payload is not received if the private channel key is set.
1573 Affected file lib/silcclient/command_reply.c and the
1574 lib/silcclient/client_channel.c.
1576 * When the CMODE_CHANGE notify is sent and the channel private
1577 key mode is removed the channel key must be re-generated in
1578 other cells as well. Added this support for the router in the
1579 silcd/packet_receive.c.
1581 * Added new local command NOTICE to send notice message on
1582 channel. Affected file silc/local_command.[ch].
1584 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1586 * Added new local command ME to the client. It is used to send
1587 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
1588 some action. Affected file silc/local_command.[ch].
1590 * Changed channel_message and private_message client operations
1591 to deliver the message flags to the application. Added also
1592 the `flags' arguments to the silc_client_send_channel_message
1593 and silc_client_send_private_message functions. Affected file
1596 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1598 * Redefined the Private Message Payload to support private message
1599 keys and to support the new private message flags. Updated
1600 the protocol specs. Flags makes it possible to have for example
1601 CTCP style messages.
1603 * Added new type SilcPrivateMessagePayload and defined an API
1604 for it in the lib/silcclient/silcprivate.[ch].
1606 * Tested private message private keys successfully. Tested the
1607 private message key set, unset and list commands with the new
1610 * Redefined the Channel Message Payload to include the channel
1611 message flags (equal with private message flags) to support
1612 for example CTCP style messages.
1614 * Defined some of the message (for channel and private message)
1615 flags. Updated the protocol specs and added the flags to the
1616 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
1618 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1620 * Added SilcKeyAgreementStatus type to the key agreement routines
1621 to indicate the current status and error if one occured.
1622 The status types are defined in the lib/silcclient/silcapi.h.
1624 * Added new local command KEY that is used to set and unset private
1625 keys for channels, set and unset private keys for private messages
1626 with remote clients and to send key agreement requests and
1627 negotiate the key agreement protocol with remote client. The
1628 key agreement is supported only to negotiate private message keys,
1629 it currently cannot be used to negotiate private keys for channels,
1630 as it is not convenient for that purpose.
1632 * Fixed a minor pending callback setting bug in the function
1633 silc_client_get_client_by_id_resolve, now the function works.
1634 Affected file lib/silcclient/idlist.c.
1636 * Added function silc_net_get_local_port to get local bound
1637 port by socket. Added to lib/silcutil/silcnet.[ch].
1639 * Added `sockets' and `sockets_count' fields to the SilcClient
1640 object. They hold the sockets of the listenning sockets in
1641 the client. Listenning sockets may be for example the key
1642 agreement server. Affected file lib/silcclient/client.[ch].
1643 Added functions the silc_client_add_socket and the
1644 silc_client_del_socket. They are exported to the application
1647 * Added ~./silc/clientkeys to support other client's public keys.
1649 * Renamed verify_server_key client operation to verify_public_key
1650 and added one argument to indicate the type of the connection
1651 (server, client etc.).
1653 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1655 * Added silc_server_connection_auth_request to handle the
1656 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
1657 silcd/packet_receive.[ch].
1659 * Added silc_server_send_connection_auth_request into the
1660 silcd/packet_send.c to send the connection auth request packet.
1662 * Cleaned up the silcd/protocol.c a bit and fixed some memory
1665 * Fixed the public key authentication in responder side in the
1666 server. The `auth_data' pointer includes the SilcPublicKey
1667 not the path to the public key. Affected file silcd/protocol.c.
1669 * Implemented the public key authentication in the initiator side
1670 in the server. Affected file silcd/protocol.c.
1672 * Removed the [RedirectClient] config section from the server
1673 configuration. Is not needed and I don't want to implement it.
1675 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1677 * Cleaned up the CMODE command in the server. It now works
1678 correctly and supports all the modes defined in the protocol.
1679 Affected file is silcd/command.c.
1681 * Added `hmac_name' field to the SilcChannelEntry in the server
1682 to hold the default HMAC of the channel. It can be set when
1683 creating the channel (with JOIN command). Affected files
1686 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
1687 type to indicate the change of the current cipher and hmac
1688 on the channel. Client can safely ignore the <cipher> argument
1689 (if it chooses to do so) since the CHANNEL_KEY packet will
1690 force the channel key change anyway. The <hmac> argument is
1691 important since the client is responsible of setting the new
1692 HMAC and the hmac key into use.
1694 * Fixed the CMODE command in the client library as well.
1696 * Tested CMODE command in router environment successfully.
1698 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1700 * Show the version of the remote client (or server) when connecting
1701 to the server. It is logged to the log file. Affected file
1702 is silcd/protocol.c.
1704 * Fixed the KILLED notify handling in the client library. The
1705 client must be removed from all channels when receiving the
1708 Also, do not remove the client entry when giving the KILL
1709 command but when the KILLED notify is received.
1711 * Removed silc_idlist_find_client_by_nickname from the server.
1712 Not needed anymore. Affected files silcd/idlist.[ch].
1714 * Implemented the CHANNEL_CHANGE notify type handling to the
1715 server. Affected file silcd/server.c.
1719 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1721 * Added silc_server_send_notify_invite to send the INVITE
1722 notify between routers.
1724 * Implemented the INVITE command correctly to the server.
1726 * Implemented the INVITE notify type handling in the server.
1728 * Implemented the INVITE command to the client library and on the
1731 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1733 * Added function silc_server_get_client_resolve to find the
1734 client entry by ID from all ID lists and then resolve it
1735 (using WHOIS) if it cannot be found. Affected file is
1738 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1740 * Implemented the BAN command to the client library.
1742 * The JOIN command in the server now checks the invite list
1745 * Changed the silc_command_reply_payload_encode_va and the
1746 silc_command_payload_encode_va to support that if argument is
1747 NULL it ignores and checks the next argument. Affected file
1748 lib/silccore/silccommand.c.
1750 * Added silc_server_send_notify_ban to send the BAN notify
1751 type between routers.
1753 * Chaned the silc_notify_payload_encode to support that if
1754 argument is NULL it ignores and checks the next argument.
1755 Affected file lib/silccore/silcnotify.c.
1757 * Tested ban lists in router environment successfully.
1759 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1761 * Implemented BAN command to the server, in silcd/command.[ch].
1763 * Removed the BAN and INVITE_LIST modes from the CMODE command
1766 * Added function silc_string_match to regex match two strings.
1767 Affected files lib/silcutil/silcutil.[ch].
1769 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1771 * Redefined parts of the SilcChannelEntry in the server to support
1772 the new ban and invite lists.
1774 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * Redefined the INVITE command. The same command can be used to
1777 invite individuals to the channel but also to manage the invite
1778 list of the channel (to add to and remove from the invite list).
1779 Updated the protocol specs.
1781 * Added new command SILC_COMMAND_BAN that can be used to manage
1782 the ban list of the channel. Updated the protocol specs.
1784 * Removed the channel modes: the SILC_CMODE_BAN and the
1785 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
1786 in the CMODE command. The equivalent features are now available
1787 using INVITE and BAN commands. Updated the protocol specs.
1789 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
1790 in the network about change in the current ban list. The notify
1791 type is not used by the client.
1793 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
1794 support the invite lists.
1796 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * Added new function silc_string_regexify that converts string
1799 including wildcard characters into regex string that can
1800 be used by the GNU regex library. Added into the file
1801 lib/silcutil/silcutil.[ch].
1803 Added silc_string_regex_combine to combine to regex strings
1804 into one so that they can be used as one regex string by
1805 the GNU regex library. Added into the file
1806 lib/silcutil/silcutil.[ch].
1808 Added silc_string_regex_match to match two strings. It returns
1809 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
1811 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1813 * Imported GNU regex to the soruce tree into lib/contrib.
1814 Fixed some compiler warning from the regex.c.
1816 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Fixed MOTD command in the server to work in router environment.
1820 * Fixed the MOTD command in the client library to support
1821 the server argument in the command.
1823 * Added `nickname_len' argument to the silc_idlist_add_client
1824 in the server, as the `nickname' argument may be binary data
1827 * Added silc_idlist_get_channels to return all channels from
1830 * Implemented LIST command to the server. Affected file is
1833 * Implemented the LIST command to the client library and on the
1836 * Added [<user count>] argument to the LIST command reply.
1837 With private channels the user count is not shown.
1839 * Updated TODO and README.
1841 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1843 * The client entry's data.registered must be TRUE even with
1844 global client entry on global client list. The data.registered
1845 is used to check whether the client is anymore in the network,
1846 for example with WHOWAS command so it must be valid.
1848 * Fixed the WHOWAS command in the server. It now actually works
1849 in router environment. Added function into silcd/command_reply.c
1850 silc_server_command_reply_whowas_save.
1852 * Added silc_idlist_purge function to the silcd/idlist.c
1853 to periodically purge the ID Cache.
1855 * Fixed INFO command in the server. It works now in router
1856 environment. Added <server name> argument to the INFO command
1857 reply. Updated the protocol specs.
1859 * Fixed minor bug in silc_idcache_purge to not purge if the
1860 expire value is zero.
1862 * Fixed various bugs in WHOIS and IDENTIFY command handling as
1863 they were buggy because of the WHOWAS information.
1865 * Fixed local command MSG to handle the async resolving of
1866 the remote client properly. It used to fail the first MSG.
1867 Affected file silc/local_command.c.
1869 * Added `data_len' field to SilcIDCache context.
1871 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1873 * Update TODO. Todo in commands in the server.
1875 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1877 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1878 used by routers as broadcast packet to inform other routers
1879 about the changed user mode.
1881 Implemented the notify handling in the server. Affected file is
1882 silcd/packet_receive.c. Added the function
1883 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1885 * Added new generic Channel Payload and deprecated the New Channel
1886 Payload. The New Channel Payload is now the generic Channel
1889 * Added new argument `mode' to the silc_server_send_new_channel
1890 as it is required in the Channel Payload now.
1892 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1893 and created a new and real SilChannelPayload to represent the
1894 new generic Channel Payload. Implemented the encode/decode
1895 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1897 * Added silc_server_get_client_channel_list to return the list
1898 of channels the client has joined for WHOIS command reply.
1899 Affected file silcd/server.[ch].
1901 * Implemented the channel list sending in the WHOIS command reply
1902 in server and in the client.
1904 Implemented the channel list displaying on the user interface
1905 as well. Affected file silc/client_ops.c.
1907 * Added silc_channel_payload_parse_list to parse list of Channel
1908 Payloads. It returns SilcDList list of SilcChannelPayloads.
1909 Client for example can use this function to parse the list of
1910 channels it receives in the WHOIS command reply. The caller
1911 must free the list by calling silc_channel_payload_list_free.
1912 Affected files lib/silccore/silcchannel.[ch].
1914 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1916 * Added one new argument <user mode> to the WHOIS command reply
1917 to return the mode of the user in SILC. Updated the protocol
1920 Implemented it to the server and client.
1922 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1924 * Fixed the mode printing on the user interface on joining.
1925 Affected file silc/client_ops.c.
1927 * Implemented the UMODE command and user modes in general to the
1928 client library and to the user interface.
1930 * Implemented the UMODE command to the server.
1932 * The server now sends UNKNOWN_COMMAND error status if client sends
1933 unknown command. Affected file silcd/command.c.
1935 * All server commands now handle the command identifier the right
1936 way when sending the command reply to the client. The client can
1937 use to identify the command replies with the identifier.
1939 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1941 * Added silc_server_get_client_route to resolve the route to
1942 the client indicated by the client ID. Affected file is
1945 * Added silc_server_relay_packet as general function to relay
1946 packet to arbitrary destination. This deprecates functions
1947 like _send_private_message_key, _relay_notify etc. Affected
1948 file is silcd/packet_send.[ch].
1950 Removed silc_server_send_key_agreement,
1951 silc_server_send_private_message_key and
1952 silc_server_packet_relay_notify functions from the file
1953 silcd/packet_send.[ch].
1957 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1958 server. Affected file silcd/packet_receive.[ch].
1960 * Implemented the KILL command to the client. Implemented the
1961 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1962 Affected files lib/silcclient/command[_reply].c and
1963 lib/silcclient/client_notify.c. Implemented the KILL notify
1964 printing in the user inteface.
1966 * Fixed a lot silc_parse_nick memory leaks from the client
1967 library in the file lib/silcclient/command.c.
1969 * Changed the silc_server_send_notify_on_channels's `sender'
1970 argument from SilcSocketConnection to SilcClientEntry to
1971 check the sender as entry and not as connection object and not
1972 to send to the client provided as argument. The affected file
1973 is silcd/packet_send.[ch].
1975 * The notify packets that are destined directly to the client used
1976 to not to be processed by the server. Now changed that and the
1977 server processes all notify packets. After relaying the packet
1978 to the client the notify packet is processed in the server.
1980 * The silc_server_free_client_data now checks whether there is
1981 pending outgoing traffic for the client and purges the data to
1982 the network before removing the client entry.
1984 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1986 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1987 an client is killed from the SILC Network. Updated the protocol
1990 Added new function silc_server_send_notify_killed to the
1991 silcd/packet_send.[ch].
1993 * Added function silc_server_packet_relay_notify to relay notify
1994 packets that are destined directly to a client. In this case
1995 the server does not process the notify packets but merely relays
1996 it to the client. Affected file silcd/packet_send.[ch].
1998 Added also silc_server_packet_process_relay_notify to check
1999 whereto relay the notify. Affected file is
2000 silcd/packet_receive.[ch].
2002 * Implemented the KILL command to the server.
2006 * Added the backup schema desgined last fall to the protocol
2007 specs for everyone to see. The specification is in the
2008 *-spec-xx.txt draft and the packet type definitions for the
2009 backup routers is in *-pp-xx.txt draft. Thusly, added also
2010 new packet type SILC_PACKET_CELL_ROUTERS.
2012 * A big security problem in the implementation discovered. The
2013 signoff of an client did not cause new channel key generation
2014 which it of course should've done. The channel keys must be
2015 always re-generated when client leaves (or signoffs) the channel.
2016 The silc_server_remove_from_channels funtion now handles
2017 the channel key re-generation.
2019 * Added `sender' argument to the silc_server_send_notify_on_channels
2020 to not to send the client provided as argument. Affected file
2021 silcd/packet_send.[ch].
2023 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2025 * Implemented OPER and SILCOPER commands into the server and
2028 * Added silc_auth_verify and silc_auth_verify_data to verify
2029 the authentication directly from the authentication payload.
2030 It supports verifying both passphrase and public key based
2031 authentication. Affected file lib/silccore/silcauth.[ch].
2033 * Added `hash' field to the SilcIDListData structure. It is the
2034 hash negotiated in the SKE protocol. Affected file is
2037 * Slight redesigning of the SilcAuthPayload handling routines.
2038 Do not send SilcPKCS but SilcPublicKey as argument.
2040 * Implemented the public key authentication support to the
2041 serverconfig. The public key is loaded from the provided path
2042 and saved as authentication data to void * pointer. Thus,
2043 changed the unsigned char *auth_data to void *auth_data;
2045 * Fixed SHUTDOWN command to send the reply before the server
2046 is shutdown. :) Affected file silcd/command.c.
2048 * Fixed fatal bug in CONNECT command. The hostname was invalid
2049 memory and server crashed. Affected file silcd/command.c.
2051 * Fixed fatal bug in CLOSE command. The server_entry became
2052 invalid but was referenced later in the command. Affected file
2055 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2057 * Fixed fatal bug in failure packet handling. Server ignored
2058 the failure and thus crashed when it came.
2062 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2064 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2065 that the command may be executed only once in (about) 2 seconds.
2066 The old SILC_CF_LAG flag is same but allows command bursts up
2067 to five before limiting.
2069 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2070 server code. Various commands now includes the CF_LAG_STRICT
2071 flag to disallow any kind of miss-use of the command.
2073 * Fixed the silc_buffer_unformat to not to allocate any data
2074 if the length of the data is zero. It used to allocate the
2075 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2077 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2079 * Changed the format of AdminConnection configuration section
2080 in the server. Added username of the admin to the format.
2081 Affected files silcd/serverconfig.[ch].
2083 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2084 to return admin configuration data by host, username and/or
2087 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2089 * Implemented WHOWAS command to the server. Added the functions:
2091 silc_server_command_whowas_parse,
2092 silc_server_command_whowas_send_reply,
2093 silc_server_command_whowas_from_client and
2094 silc_server_command_whowas_from_server
2096 * Added <Client ID> argument to the WHOWAS command reply. Updated
2097 the protocol specs accordingly.
2099 * Implemented WHOWAS command and command_reply to the client
2102 Implemented the WHOWAS printing on the user interface.
2104 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2106 * Added new argument to the WHOWAS command reply, the real name.
2107 It is an optional argument. Updated the protocol specs.
2109 * Added SilcIDCacheDestructor callback that is registered when
2110 the SilcIDCache is allocated. The callback is called when
2111 an cache entry in the ID Cache expires, or is purged from the
2112 cache. Added into lib/silccore/idcache.[ch].
2114 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2115 to destruct the client entries when the cache entry expires.
2116 Other ID Cache's in server and in the client library ignores
2119 * If the ID Cache entry's `expire' field is zero then the entry
2120 never expires. Added boolean `expire' argument to the
2121 silc_idcache_add function in the lib/silccore/idcache.[ch].
2122 If it is TRUE the default expiry value is used.
2124 * Added silc_server_free_client_data_timeout that is registered
2125 when client disconnects. By default for 5 minutes we preserve
2126 the client entry for history - for WHOWAS command.
2128 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2130 * Added support to the server to enforce that commands are not
2131 executed more than once in 2 seconds. If server receives
2132 commands from client more frequently, timeout is registered
2133 to process the commands. Affected file silcd/command.c.
2134 Added new function silc_server_command_process_timeout.
2136 * Changed NICK_NOTIFY handling in client library to check that
2137 if the client's nickname was changed, so there is no need to
2138 resolve anything from the server.
2140 * Removed error printing from the WHOIS and IDENTIFY commands.
2141 If error occurs then it is ignored silently in the client library.
2142 The application, however, may map the received error to
2143 human readable error string. The application currently maps
2144 the NO_SUCH_NICKNAME error to string.
2146 * Made the command status message public to the application. Moved
2147 them from lib/silcclient/command_reply.c to
2148 lib/silcclient/command_reply.h. The application can map the
2149 received command status to the string with the
2150 silc_client_command_status_message function.
2152 * Added check to the server to check that client's ID is same
2153 as the Source ID in the packet the client sent. They must
2156 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2158 * Added dist-bzip hook to the Makefile.am to make bzip2
2159 compressed distributions.
2161 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2163 * Server now enforces the maximum length for the nickname and
2164 the channel as protocol specification dictates. 128 bytes for
2165 nickname and 256 bytes for channel name.
2167 * Moved the WHOIS printing to the application. The client libary
2168 does not print out the WHOIS information anymore, the application
2169 must do it. Renamed silc_client_command_reply_whois_print to
2170 the silc_client_command_reply_whois_save.
2172 The client's idle time is also sent to the application now, and
2173 the idle is shown on screen.
2175 * Added silc_client_command_reply_identify_save to save the
2176 received IDENTIFY entries.
2178 * Do not check for channel private keys in message sending and
2179 reception if the channel does not have the PRIVKEY mode set.
2180 Affected file lib/silclient/client_channel.c.
2182 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2184 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
2185 just surfaced after chaning the JOIN procedure.
2187 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2189 * Added silc_client_get_clients_by_list to get client entries
2190 from Client ID list, that is returned for example by JOIN
2191 and USERS command replies. The application should use this
2192 function for example when JOIN command reply is received to
2193 resolve the clients already on the channel (library does not
2194 do that anymore as USERS command reply is not used in the JOIN
2195 procedure anymore). Affected files lib/silcclient/silcapi.h and
2196 lib/silcclient/idlist.c.
2198 * JOIN command reply and USERS command reply returns now SilcBuffer
2199 pointers instead of unsigned char pointers when returning
2200 the client list and mode list.
2202 * Added <Client ID> argument to the JOIN command reply, mainly
2203 for the server to identify for which client the command was
2204 originally sent. Updated protocol specs accordingly.
2206 * Added SilcDlist private_key pointer to the SilcChannelEntry
2207 in the client to support the channel private keys. Affected
2208 file is lib/silcclient/idlist.h.
2210 * Added SilcChannelPrivateKey argument to the function
2211 silc_client_send_channel_message so that application can choose
2212 to use specific private ke if it wants to. If it is not provided,
2213 the normal channel key is used, unless private keys are set.
2214 In this case the first (key that was added first) is used
2215 as the encryption key.
2217 * Implemented the support for channel private key handling.
2218 Implemented the following functions:
2220 silc_client_add_channel_private_key,
2221 silc_client_del_channel_private_keys,
2222 silc_client_del_channel_private_key,
2223 silc_client_list_channel_private_keys and
2224 silc_client_free_channel_private_keys
2226 Affected file lib/silcclient/client_channel.c.
2228 * Added the support for the private keys in the channel message
2229 sending and encryption and in the message reception and
2230 decryption. Affected funtions are
2231 silc_client_send_channel_message and silc_client_channel_message.
2233 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2235 * Added SKE's key verify callback to the client library's
2236 KE protocol context. Affected files lib/silcclient/protocol.[ch].
2238 * Removed the statement that server (or router) must send USERS
2239 command reply when joining to the channel so that the client
2240 knows who are on the channel. Instead, the client list and
2241 client's mode list is now sent in the JOIN command reply to the
2242 client who joined channel. This is better solution.
2244 * Added function silc_server_get_users_on_channel and function
2245 silc_server_save_users_on_channel to the silcd/server.[ch].
2247 * Removed function silc_server_command_send_users from the
2250 * Do not show topic on the client library anymore. The topic is
2251 sent in the command reply notify to the application and the
2252 application must show the topic now.
2254 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2256 * Added client searching by nickname hash into the IDENTIFY and
2257 WHOIS commands in the server as they were clearly missing from
2258 them. Affected file is silcd/command.c.
2260 * Fixed a bug in private message receiving in the client library.
2261 The remote ID was freed and it wasn't supposed, now it is
2264 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2266 * Minor fix to the channel payload; allocate the data area, as it
2267 needs to be of specific length.
2269 * If the key agreement port is zero then the operating
2270 system will define the bound port. Affected files are
2271 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
2273 * Added new function silc_channel_payload_decrypt into the file
2274 lib/silccore/silcchannel.[ch].
2276 * Moved the channel message etc, check from silc_packet_decrypt
2277 to applications. The library calls now a generic
2278 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
2279 when the packet is either normal or special. This was done to
2280 allow more wide range of checking that was not allowed when
2281 the code was in library. Now applications can do virtually any
2282 checks to the packet and return to the library the decision how
2283 the packet should be processed. Affected files are
2284 lib/silccore/silcpacket.[ch].
2286 Added silc_server_packet_decrypt_check to the server and
2287 silc_client_packet_decrypt_check to the client library.
2289 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
2290 to send with specified source and destination information.
2292 * Channel message delivery between routers was broken after the
2293 channel key distribution was fixed earlier. The channel key
2294 was used be to distributed to other routers as well which is not
2295 allowed by the protocol. Now this is fixed and channel keys
2296 really are cell specific and the channel message delivery between
2297 routers comply with the protocol specification.
2299 * Fixed various commands in server to check also the global list
2300 for the channel entry and not just the local list. The affected
2301 file silcd/command.c.
2303 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2305 * Added assert()s to buffer formatting and unformatting routines
2306 to assert (if --enable-debug) when error occurs. Affected
2307 file: lib/silcutil/silcbuffmt.c.
2309 * Changed to auto-reconnect to check whether the remote host is
2310 router and register the re-connect timeout if it is. It used
2311 to check that whether we are normal server, but router must do
2312 auto-reconnect with another router as well. Affected file
2315 * Removed the [<key len>] option from CMODE command as the cipher
2316 name decides the key length, nowadays. See the defined ciphers
2317 from the protocol specification.
2319 * Added [<hmac>] option to the CMODE command to define the HMAC
2320 for the channel. Added SILC_CMODE_HMAC channel mode.
2322 * Added [<hmac>] option for the JOIN command so that user can
2323 select which HMAC is used to compute the MACs of the channel
2326 * Added Hmac field to the Channel Message Payload. The integrity
2327 of plaintext channel messages are now protected by computing
2328 MAC of the message and attaching the MAC to the payload. The
2329 MAC is encrypted. Now, it is clear that this causes some
2330 overhead to the size of the packet but rationale for this is that
2331 now the receiver can verify whether the channel message decrypted
2332 correctly and also when private keys are set for the channel the
2333 receiver can decrypt the packet with several keys and check from
2334 the MAC which key decrypted the message correctly.
2336 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
2337 lib/silccrypt/silccipher.[ch].
2339 * Added silc_hash_len to return the digest length into the
2340 lib/silcrypt/silchash.[ch].
2342 * Rewrote parts of Silc Channel Payload interface in the
2343 lib/silccore/silcchannel.[ch]. The encode function now also
2344 encrypts the packet and parse function decrypts it.
2346 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2348 * Fixed a minor formatting bug in the SKE's key material processing.
2349 It actually might have processed the keys wrong way resulting
2352 * Redefined the mandatory HMAC algorithms and added new algorithms.
2353 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
2354 and hmac-md5 truncated to 96 bits. The mandatory is now
2355 hmac-sha1-96. Rest are optional (including the one that used
2356 to be mandatory). Rationale for this is that the truncated HMAC
2357 length is sufficient from security point of view and can actually
2358 make the attack against the HMAC harder. Also, the truncated
2359 HMAC causes less overhead to the packets. See the RFC2104 for
2362 * Added new [hmac] configuration section. The SKE used to use
2363 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
2364 is of course wrong. The official names that must be proposed in
2365 the SKE are the ones defined in the protocol specification
2366 (hmac-sha1-96 for example). The user can configure any hmac
2367 using any hash function configured in the [hash] section. At
2368 least, the mandatory must be configured.
2370 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
2372 * Added HMAC list to the SKE proposal list. It has now both
2373 hash algorithm list and HMAC list. This makes the protocol
2374 incompatible with previous versions. The SKE now seems to work
2375 the way it is supposed to work, for the first time actually.
2377 * Defined plain Hash algorithms to the protocol specification.
2380 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2382 * Implemented support for key agreement packets into the server.
2383 Added functions silc_server_key_agreement and
2384 silc_server_send_key_agreement. Other than these functions,
2385 server has nothing to do with this packet.
2387 * Added support for private message key packets into the server.
2388 Added functions silc_server_private_message_key and
2389 silc_server_send_private_message_key.
2393 * Changed the silc_[client|server]_protocol_ke_set_keys to be
2394 called in the protocol's final callback instead in the END
2395 protocol state. This makes a little more sense and in the same
2396 time in client we can use the same protocol routines for normal
2397 key exchange and to key agreement packet handling as well.
2399 * Added to both client's and server's KE protocol context the
2400 SilcSKEKeyMaterial pointer to save the key material. We will
2401 bring the key material to the protocol's final callback by doing
2402 this. The final callback must free the key material.
2404 * Added SKE's packet_send callback into client's KE protocol
2405 context so that the caller can choose what packet sending function
2406 is used. This way we can use different packet sending when
2407 doing normal SKE when doing key agreement packet handling (in
2408 the key agreement packet handling we do not want to encrypt
2411 * Implemented the responder side of the key agreement routines
2412 in the client. The client can now bind to specified port and
2413 accept incoming key negotiation. The key material is passed
2414 to the application after the protocol is over.
2416 * Implemented the processing of incoming Key Agreement packet
2417 in the client. Added function silc_client_key_agreement to
2420 * Implemented the intiator side of the key agreement routines
2421 in the client. The client can now initiate key agreement with
2422 another remote client. The key material is passed to the
2423 application after the protocol is over.
2425 * Created client_keyagr.c to include all the key agreement
2428 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
2429 SILC_TASK_CALLBACK except that it is not static.
2431 * Created client_notify.c and moved the Notify packet handling
2432 from the client.[ch] into that file.
2434 * Created client_prvmsg.c and moved all private message and
2435 private message key routines from the client.[ch] into that file.
2437 * Create client_channel.c and moved all channel message and
2438 channel private key routines from the client.[ch] into that file.
2440 * Changed silc_client_get_client_by_id_resolve to resolve with
2441 WHOIS command instead of IDENTIFY command, in the file
2442 lib/silclient/idlist.c.
2444 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2446 * Implemented the SKE's responder side to the Client library.
2448 * When FAILURE is received to the protocol do not trust it
2449 blindly. Register a timeout to wait whether the remote closes
2450 the connection as it should do it, only after that process the
2451 actual failure. This was changed to both client and server.
2453 * Added client_internal.h to include some of the structures
2454 there instead of client.h in lib/silcclient/.
2456 * Added function silc_task_unregister_by_callback to unregister
2457 timeouts by the callback function.
2459 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2461 * Some "Incomplete WHOIS info" errors has been appearing on the
2462 log files. Took away the entry->userinfo check from WHOIS
2463 reply sending. The entry->userinfo is now " " if client did not
2464 provide one. I thought this was fixed earlier but something
2465 is wrong still. Let's see if the error still appears.
2467 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2469 * Fixed a minor bug in the login when the channel key is
2470 re-generated in the server. It used to generate the key in
2471 wrong order and thus caused problems in the channel traffic.
2473 * Fixed a minor bug in channel key distsribution after
2474 KICK command. The key was not sent to the router even though
2477 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2479 * Added silc_ske_process_key_material_data as generic routine
2480 to process any key material as the SILC protocol dictates. The
2481 function is used by the actual SKE library but can be used by
2482 applications as well. This relates to the private message keys
2483 and the channel private keys since they must be processed the
2484 same way the normal SILC session keys. The protocol dictates
2485 this. Affected files: lib/silcske/silcske.[ch].
2487 Added also silc_ske_free_key_material to free the
2488 SilcSKEKeyMaterial structure.
2490 * Defined silc_cipher_set_key function to set the key for
2491 cipher without using the object's method function. The affected
2492 files: lib/silccrypt/silccipher.[ch].
2494 * Implemented silc silc_client_add_private_message_key,
2495 silc_client_add_private_message_key_ske,
2496 silc_client_del_private_message_key,
2497 silc_client_list_private_message_keys and
2498 silc_client_free_private_message_keys functions in the
2501 Added functions silc_client_send_private_message_key to send
2502 the Private Message Key payload and silc_client_private_message_key
2503 to handle incoming Private Message Key payload.
2505 * Added Cipher field to the Private Message Key payload to set
2506 the cipher to be used. If ignored, the default cipher defined
2507 in the SILC protocol (aes-256-cbc) is used.
2509 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2511 * Removed lib/silcclient/ops.h file.
2513 Redefined parts of the SILC Client Library API. Created new
2514 file silcapi.h that deprecates the ops.h file and defines the
2515 published Client Library API. Defined also private message key
2516 API and channel private key API into the file.
2518 This is the file that the application must include from the
2519 SILC Client Library. Other files need not be included by
2520 the application anymore.
2522 * Added new key_agreement client operation callback and also
2523 defined the Key Agreement library API for the application.
2525 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2527 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
2528 is used by clients to request key negotiation between another
2529 client in the SILC network. If the negotiation is started it
2530 is performed using the SKE protocol. The result of the
2531 negotiation, the secret key material, can be used for example
2532 as private message key.
2534 Implemented the Key Agreement payload into the files
2535 lib/silccore/silauth.[ch].
2537 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2539 * Redefined ciphers for the SILC protocol. Added some new ciphers
2540 and defined the key lengths for the algorithms. Changed the
2541 code accordingly. The default key length is now 256 bits.
2543 * Fixed SKE key distribution function silc_ske_process_key_material
2544 when the key length is more than 128 bits. The default key
2545 length in SILC is now 256 bits.
2547 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
2548 to indicate unsupported algorithm.
2550 * Renamed rijndael.c to aes.c and all functions as well.
2552 * Fixed a long standing channel key setting bug in client library.
2553 Weird that it has never surfaced before.
2555 * Fixed bug in channel deletion. If the entire channel is removed
2556 then it must also delete the references of the channel entry
2557 from the client's channel list as the client's channel entry and
2558 the channel's client entry share same memory.
2560 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2562 * Implemented CONNECT and SHUTDOWN commands in the client.
2564 * Implemented CLOSE command to the client.
2566 * Added the function silc_idlist_find_server_by_name into the
2567 files silcd/idlist.[ch].
2569 Added the function silc_idlist_find_server_by_conn into the
2570 files silcd/idlist.[ch].
2572 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2574 * DIE command was renamed to SHUTDOWN. Updated the both code
2577 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
2578 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
2580 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
2583 * Added function silc_server_create_connection function to create
2584 connection to remote router. My server implementation actually
2585 does not allow router to connect to normal server (it expects
2586 that normal server always initiates the connection to the router)
2587 so the CONNECT command is only good for connecting to another
2590 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2592 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
2593 or some other client was kicked from the channel.
2595 Implemented the handling of the notify type to both client
2598 Implemented silc_server_send_notify_kicked to send the KICKED
2599 notify. It is used to send it to the server's primary router.
2601 * Implemented the KICK command into server and client.
2603 * Added `query' argument to the silc_idlist_get_client function
2604 to indicate whether to query the client from server or not if
2607 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
2608 to indicate that the client is not channel founder.
2612 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2614 * Removed the rng context from SilcPacketContext structure and
2615 changed that the packet routine uses the Global RNG API.
2617 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2619 * Added support for quit message that client can "leave" on the
2620 channel when it quits the SILC. It is ditributed inside the
2621 SILC_NOTIFY_TYPE_SIGNOFF notify type.
2623 Added silc_server_free_client_data that will take the
2624 signoff message as argument.
2626 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
2628 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2630 * Updated parts of the protocol specification to keep it up
2633 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2635 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
2636 payloads in one packet.
2638 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
2639 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
2640 use now the new List flag.
2642 * Also deprecated the following packet types: REPLACE_ID,
2643 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
2645 * Added list support for Notify packet in server.
2647 * Added silc_server_send_notify_channel_change to send the
2648 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
2649 the silc_server_send_replace_id.
2651 * Added silc_server_send_notify_nick_change to send the
2652 NICK_CHANGE notify type. Deprecates the function
2653 silc_server_send_replace_id.
2655 * Added silc_server_send_notify_join to send the JOIN notify type.
2656 Deprecates the function silc_server_send_new_channel_user.
2658 * Added silc_server_send_notify_leave to send LEAVE notify type.
2659 Deprecates the function silc_server_send_remove_channel_user.
2661 * Added silc_server_send_notify_cmode and
2662 silc_server_send_notify_cumode to send CMODE and CUMODE notify
2663 types. Deprecates the silc_server_send_set_mode function.
2665 * Added SERVER_SIGNOFF notify type to indicate that server has
2666 quit. This means that all clients on the channel from that
2667 server will drop. This can be also used when netsplit happens.
2669 Deprecated REMOVE_ID packet type since it is not needed anymore
2672 Added silc_server_send_notify_server_signoff to send the
2673 SERVER_SIGNOFF notify type. Deprecates the function
2674 silc_server_send_remove_id.
2676 Added also silc_server_send_notify_signoff to send the
2677 SIGNOFF notify type.
2679 * Employed the PKCS #1. It is the mandatory way to do RSA in the
2680 SILC protocol from this day on. Changed the protocol
2681 specification as well.
2683 * Added silc_server_send_notify_topic_set to send TOPIC_SET
2684 notify type. It is used between routers to notify about
2685 topic changes on a channel.
2687 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
2690 * Partly updated the protocol specification to comply with the
2691 changes now made. It is still though a bit outdated.
2693 * The JOIN notify type now takes one extra argument <Channel ID>.
2694 The packet used to be destined to the channel but now the
2695 JOIN type may be sent as list thus it is impossible to
2696 destine it to any specific channel. By adding this argument
2697 it is again possible.
2699 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2701 * Added CREDITS file. The CHANGES and CREDITS file will appear
2702 in the distribution as well.
2704 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2706 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
2707 types in the server's silcd/packet_receive.c.
2709 * Implemented CMODE and CUMODE to work in router environment.
2711 * Fixed minor encoding and decoding buglet from the
2712 lib/silccore/silcmode.c.
2714 * Fixed buffer overflow from lib/silcclient/command.c in USERS
2717 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
2719 * Changed all SilcConfigServer* and silc_config_server* to
2720 SilcServerConfig* and silc_server_config*, respectively.
2723 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2725 * Associated the ID (client or server ID) to the Authentication
2726 Payload to avoid any possibility of forging. Updated the
2727 protocol specification and the code accordingly.
2729 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2731 * The RSA key length is now save to the RsaKey context in the
2732 key generation process in lib/silccrypt/rsa.c. The key length
2733 is now used to figure out the maximum size of the block allowed
2734 to be encrypted/signed.
2736 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
2737 is equivalent to the silc_mp_mp2bin but does not allocate any
2740 * Changed silc_mp_mp2bin API to take length argument. If it is
2741 non-zero then the buffer is allocated that large. If zero, then
2742 the size is approximated using silc_mp_sizeinbase, which however
2745 * Created Global RNG API which is global RNG that application can
2746 initialize. After initializing, any routine anywhere in the
2747 code (including library) can use RNG without allocating a new
2748 RNG object. This was done to allow this sort of use of the
2749 RNG in code that has no chance to allocate RNG object. All
2750 applications currently allocate this and many routines in the
2751 library use this. Affected file lib/silccrypt/silcrng.[ch].
2753 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
2754 it to use the Global RNG API.
2756 * Defined Authentication Payload into protocol specification that
2757 is used during SILC session to authenticate entities. It is
2758 used for example by client to authenticate itself to the server
2759 to obtain server operator privileges.
2761 Implemented this payload into the lib/silccore/silcauth.[ch].
2762 Implemented also routines for public key based authentication
2763 as the new protocol specification dictates.
2765 Moved definitions of different authentication methods from
2766 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
2768 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
2769 silc_pkcs_verify and silc_pkcs_sign_with_hash and
2770 silc_pkcs_verify_with_hash functions into the file
2771 lib/silccrypt/silcpkcs.[ch].
2773 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2775 * The client entry's userinfo pointer must be always valid.
2776 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
2777 will fail since it requires the userinfo. Now, the userinfo
2778 is allocated as "" if actual userinfo does not exist. Actually,
2779 it must exist and it is totally Ok to drop client connections
2780 that does not announce the userinfo. However, we will make
2781 this workaround for now.
2783 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
2784 to return the remote port by socket.
2786 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2788 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
2789 SILC_SERVER_PENDING_EXEC and added an new macro
2790 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
2791 data or when error occurs while processing the pending command.
2793 Added new argument `destructor' into silc_server_command_pending
2794 and to the SilcServerCommandPending object. This destructor is
2795 now called after calling the pending callback or if error occurs
2796 immediately. If error occurs the actual pending callback won't
2797 be called at all - only the destructor. The destructor may be
2798 NULL if destructor is not needed.
2800 All this applies for client library code as well. Similar
2801 changes were made there as well for the pending commands.
2803 In the client, the application must now allocate the
2804 SilcClientCommandContext with the silc_client_command_alloc
2807 * Added reference counter to the SilcServerCommandContext. Added
2808 function silc_server_command_alloc and silc_server_command_dup
2811 Same type of functions added to the client library for the same
2814 * Removed the cmd_ident from IDListData away since it is now
2815 global for all connections. It is the command identifier used
2816 in command sending and with pending commands. The affected file
2819 * Added reference counter to the SilcSocketConnection objecet to
2820 indicate the usage count of the object. The object won't be
2821 freed untill the reference counter hits zero. Currently only
2822 server uses this, and client ignores it. The client must be
2823 set to use this too later. The affected files are
2824 lib/silccore/silcsockconn.[ch]. Added also the function
2825 silc_socket_dup to increase the reference counter.
2827 This was mainly added because it is possible that the socket
2828 is removed underneath of pending command or other async
2829 operation. Now it won't be free'd and proper DISCONNECTING
2830 flags, etc. can be set to avoid sending data to connection that
2831 is not valid anymore.
2833 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
2834 the connection. After that it sets SILC_SET_DISCONNECTED.
2835 It is, however, possible that the socket data is not still freed.
2836 The silc_server_packet_process now checks that data is not
2837 read or written to connection that is DISCONNECTED. The socket
2838 get's freed when the reference counter hits zero.
2840 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2842 * Changed the client operation API: channel_message operation's
2843 `sender' is now the client entry of the sender, not the nickname
2844 and the `channel' is the channel entry, not the channel name.
2846 In the private_message operation the `sender' is now also the
2847 client entry of the sender not the nickname.
2849 Affected file is lib/silcclient/ops.h and all applications
2850 using the client operations.
2852 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Moved the calling of ops->connect() from connect_to_server_final
2855 into receive_new_id functin since that is the point when the
2856 client is actually allowed to send traffic to network. The
2857 affected file is lib/silcclient/client.c.
2859 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2861 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
2862 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
2863 (if needs broadcasting) instead of broadcasting the packets one
2864 by one which would make a burst in the network traffic.
2866 * Added `broadcast' argument to the functions in silcd/server.[ch]
2867 silc_server_create_new_channel[_with_id] to indicate whether
2868 to send New Channel packet to primary router.
2870 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * Added new function into the silcd/server.[ch] files:
2873 silc_server_create_new_channel_with_id to create new channel with
2874 already existing Channel ID.
2876 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2877 lib/silccore/silcpacket.h. This packet is used t send list of
2878 Set Mode payloads inside one packet. Server uses this to set
2879 the modes for the channels and clients on those channels, that it
2880 announced to the router when it connected to it. The protocol
2881 specification has been updated accordingly.
2883 * The silc_server_new_channel did not handle the packet coming
2884 from normal server as it normally does not send that. However,
2885 when it announces its channels it does send it. Implemented
2886 the support for that.
2888 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2889 into the file lib/silccore/id.h.
2891 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * Fixed memory leaks in the functions silc_idlist_del_client,
2894 silc_idlist_del_channel and silc_idlist_del_server in the file
2895 silcd/idlist.c. All of those leaked like a sieve.
2897 * Fixed some small memory leaks in the client's function
2898 silc_client_notify_by_server.
2900 * Added functions into silcd/server.c: silc_server_announce_clients,
2901 silc_server_announce_channels and silc_server_announce_server.
2902 These functions are used by normal and router server to announce
2903 to its primary router about clients, channels and servers (when
2904 router) that we own. This is done after we've connected to the
2907 These functions effectively implements the following packet types:
2908 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2909 and SILC_PACKET_NEW_ID_LIST.
2911 * Added new functions into the silcd/packet_receive.[ch]:
2912 silc_server_new_id_list, silc_server_new_channel_list and
2913 silc_server_new_channel_user_list to handle the incoming
2914 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2916 * Added support of changing Channel ID in the function
2917 silc_server_replace_id. If the server that announces a channel
2918 to the router already exists in the router (with same name but
2919 with different Channel ID), router is responsible to send
2920 Replace ID packet to the server and force the server to change
2921 the Channel ID to the one router has.
2923 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2924 client that the Channel ID has been changed by the router. The
2925 normal server sends this to the client. Client must start using
2926 the new Channel ID as the channel's ID.
2928 Implemented handling of this new type into lib/silcclient/client.c
2929 into the function silc_client_notify_by_server.
2931 * Added new function silc_idlist_replace_channel_id into the files
2932 silcd/idlist.[ch] to replace the Channel ID.
2934 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2936 * Call silc_server_command_identify_check always when processing
2937 the IDENTIFY command in silcd/command.c
2939 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2942 send keepalive packets. The packet can be sent by clients,
2943 servers and routers.
2945 Added function silc_socket_set_heartbeat into the file
2946 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2947 If not set, the heartbeat is not performed. The actual
2948 heartbeat is implemented in the low level socket connection
2949 library. However, application is responsible of actually
2952 Added silc_server_send_heartbeat to send the actual heartbeat
2953 packet into silcd/packet_send.[ch]. Server now performs
2954 keepalive with all connections.
2956 * Added silc_task_get_first function into lib/silcutil/silctask.c
2957 to return the timeout task with shortest timeout. There was a bug
2958 in task unregistration that caused problems. TODO has been
2959 updated to include that task system must be rewritten.
2961 * The client library will now resolve the client information when
2962 receiving JOIN notify from server for client that we know but
2963 have incomplete information.
2965 * Rewrote parts of silc_server_remove_from_channels and
2966 silc_server_remove_from_one_channel as they did not remove the
2967 channel in some circumstances even though they should've.
2969 * Encryption problem encountered in server:
2971 The LEAVE command used to send the Channel Key packet to the
2972 router immediately after generating it. However, the code
2973 had earlier sent Remove Channel user packet but not immediately,
2974 ie. it was put to queue. The order of packets in the router
2975 was that Channel Key packet was first and Remove Channel User
2976 packet was second, even though they were encrypted in the
2977 reverse order. For this reason, MAC check failed. Now, this
2978 is fixed by not sending the Channel Key packet immediately but
2979 putting it to queue. However, this is more fundamental problem:
2980 packets that are in queue should actually not be encrypted
2981 because packets that are sent immediately gets encrypted
2982 actually with wrong IV (and thus MAC check fails). So, packets
2983 that are in queue should be encrypted when they are sent to
2984 the wire and not when they put to the queue.
2986 However, the problem is that the current system has not been
2987 designed to work that way. Instead, the packet is encrypted
2988 as soon as possible and left to the queue. The queue is then
2989 just purged into wire. There won't be any fixes for this
2990 any time soon. So, the current semantic for packet sending
2993 o If you send packet to remote host and do not force the send
2994 (the packet will be in queue) then all subsequent packets to the
2995 same remote host must also be put to the queue. Only after the
2996 queue has been purged is it safe again to force the packet
2999 o If you send all packets immediately then it safe to send
3000 any of subsequent packets through the queue, however, after
3001 the first packet is put to queue then any subsequent packets
3002 must also be put to the queue.
3004 Follow these rules and everything works fine.
3006 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3008 * Added new function silc_server_remove_clients_by_server to
3009 remove all client entries from ID list when the server connection
3010 is lost. In this case it is also important to invalidate all
3011 client entires as they hold the invalid server entry. This
3012 fixes fatal bug when server has lost connection and will reconnect
3015 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3017 * Made some sanity checks to silc_server_daemonise like to check
3018 whether the requested user and group actually exists.
3020 * Added sanity check to SKE's silc_ske_responder_finish to check
3021 that the public and private key actually is valid.
3023 * Invalidate the client's nickname when receiving Replace ID
3024 packet and the Client ID is being replaced. This means that the
3025 server will query the nickname if someone needs it (client)
3028 * Sort the ID Cache in client library when the ID Cache data
3029 has changed (needs sorting).
3031 * Do not allow for SILC client to create several connections to
3032 several servers. The client does not support windows right now
3033 and generating multiple connections causes weird behaviour.
3035 Irssi-silc client does support windows and can handle several
3036 connections without problems, see: www.irssi.org and SILC plugin.
3038 * Fixed some places where client was added to the IDList. The
3039 rule of thumb is following (in order to get everything right):
3040 If the client is directly connected local client then the
3041 `connection' argument must be set and `router' argument must be
3042 NULL to silc_idlist_add_client function. If the client is not
3043 directly connected client then the `router' argument must
3044 bet set and the `connection' argument must be NULL to the
3045 silc_idlist_add_client function.
3047 * The funtion silc_server_packet_send_local_channel actually did
3048 not check whether the client was locally connected or not. It
3049 does that now. Fixed a bug related to LEAVE command.
3051 * Fixed Remove Channel User payload parsing bug in server's
3052 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3054 * The server's silc_server_save_channel_key now checks also the
3055 global ID list for the channel as it might not be in the local
3056 list. Fixed a bug related to LEAVE command.
3058 * Is this the end of the [<unknown>] buglet that has been lurking
3059 around for a long time? A little for loop fix in server's
3060 silc_server_command_whois_parse that is used by both IDENTIFY
3061 and WHOIS command. At least, this was a clear bug and a cause
3062 of one type of [<unknown>] buglet.
3064 * WHOIS and IDENTIFY commands call the function
3065 silc_server_command_[whois/identify]_check function even if
3066 we are not router server.
3068 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3070 * Added --with-gmp configuration option. If set the GMP
3071 is always compiled in the SILC source tree. If not set then
3072 it is checked whether the system has the GMP3 installed. If
3073 it has then the GMP won't be compiled (the system's headers
3074 and library is used), if it doesn't have it then the GMP is
3075 compiled in the SILC source tree.
3077 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3079 * Changed RSA private exponent generation to what PKCS #1
3080 suggests. We try to find the smallest possible d by doing
3081 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3082 not security fix but optimization.
3084 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Added new config entry [Identity] to fork the server and run
3087 it as specific user and group. A patch from Bostik.
3089 * Imported Dotconf configuration library into lib/dotconf.
3090 This will be used to create the SILC configuration files later.
3091 It will appear in the distsribution after this commit.
3093 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3095 * A big code auditing weekend happening. Auditing code for
3096 obvious mistakes, bugs and errors. Also, removing any code
3099 Removed files for being obsolete:
3101 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3102 inline in the file lib/silcutil/silcbuffer.h)
3104 o lib/silcutil/silcbufutil.c (the header has inline versions)
3106 Changed code to fix possible error conditions:
3108 o The buffer formatting routines now check that the destination
3109 buffer really has enough space to add the data. This applies for
3110 both buffer formatting and unformatting
3111 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3112 unformatting was changed to accomodate following rules:
3113 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3114 sent to the function while XXX_*STRING will not allocate or copy
3115 the data into the buffer. Instead it sets the pointer from the
3116 buffer into the pointer sent as argument (XXX_*STRING used to
3117 require that the pointer must be allocated already). This change
3118 makes this whole thing a bit more consistent and more optimized
3119 (note that the data returned in the unformatting with XXX_*STRING
3120 must not be freed now). The routines return now -1 on error.
3122 o Tried to find all code that use buffer_format and buffer_unformat
3123 and added return value checking to prevent formatting and
3124 especially unformatting errors and possible subsequent fatal
3127 o Changed ske->x and ske->KEY to mallocated pointers in
3128 lib/silcske/silcske.h. Fixed possible data and memory leak.
3130 o Added return value checking to all *_parse* functions. Fixed
3131 many memory leaks as well.
3133 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3134 so that buffer overflows would not happen. All code now also
3135 checks the return value as it can fail.
3137 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3139 * Added reconnection support to server if the normal server looses
3140 its connection to the router (for example if router is rebooted).
3141 The server performs normal reconnection strategy implemented
3142 to the server. Affected file silcd/server.c.
3144 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3146 * Added new packet type SILC_PACKET_SET_MODE that is used to
3147 distribute the information about changed modes (for clients,
3148 channels and clients channel modes) to all routers in the
3149 network. Updated the protocol specification accordingly.
3151 Added functions into silcd/packet_send.c and
3152 silcd/packet_receive.c: silc_server_send_set_mode,
3153 silc_server_set_mode.
3155 Added new files silcmode.[ch] into lib/silccore that implements
3156 the encoding and decoding of Set Mode Payload. Added new type
3157 SilcSetModePayload. Moved the definitions of different modes
3158 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3160 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Oops, a little mistake in server's connection authentication
3163 protocol. The protocol is not ended with FAILURE but with
3164 SUCCESS if the authentication is Ok. :) Affected file is
3167 * Implemented NICK_CHANGE notify handling in server in the file
3168 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3169 the local clients on the channel. After the changing nickname
3170 in router environment snhould work and the [<unknown>] nickname
3171 should appear no more.
3173 The silc_server_replace_id function that receives the Replace ID
3174 payload now sends the NICK_CHANGE notify type also in the file
3175 silcd/packet_receive.c
3177 * Changed WHOIS and IDENTIFY command to support the maximum amount
3178 of arguments defined in protocol specs (3328 arguments). This
3179 fixed a bug that caused problems when there were more than three
3182 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3184 * Added extra parameter, command identifier, to the
3185 silc_client_send_command so that explicit command identifier
3188 Changed that ID list routines uses specific command identifier
3189 when sending WHOIS/IDENTIFY requests to the server so that they
3190 can be identified when the reply comes back.
3192 Affected files lib/silcclient/command.[ch],
3193 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
3195 * Added `sender' argument to silc_server_packet_send_to_channel
3196 to indicaet the sender who originally sent the packet to us
3197 that we are now re-sending. Ignored if NULL. Affected file
3198 silcd/packet_send.[ch].
3200 * Added some server statistics support in silcd/server_internal.h
3201 SilcServerStatistics structure and around the server code. Also
3202 send some nice statistics information when client is connecting
3205 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3207 * Fixed channel ID decoding in server's JOIN command reply in
3208 silcd/command_reply.c
3210 * Fixed braodcasting of replace ID payload to not to send it if
3211 we are standalone server in silcd/packet_receive.c.
3213 * Fixed all channel message sending routines to not to send
3214 packets to clients that has router set, since they are routed
3215 separately in the same function earlier. Affects file
3216 silcd/packet_send.c and all channel packet sending functions.
3218 * In USERS reply, res_argv[i] are not allocated, the table
3219 is allocated. Thus changed that free the table, not its
3222 * In server's whois_check and identify_check if the client is
3223 locally connected do not send any WHOIS commands - they are not
3226 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3228 * Fixed some minor bugs in client when sending WHOIS command. The
3229 arguments was in wrong order.
3231 * Removed statis function add_to_channel from server in
3232 silcd/command.c that was previously used with the joining but
3235 * Tested USERS command in router environment successfully with two
3236 routers, two servers and two clients.
3238 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3240 * Reorganized the USERS command and command reply in client library
3241 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
3242 When the command is given by user we register a pending command
3243 callback that will reprocess the command after the reply has been
3244 received from the server. When reprocessing the packet we then
3245 display the information. Thus, the USERS information is displayed
3246 now in the command callback instead of in the command reply
3247 callback. The processing of the command is same as previously
3248 when server has sent the command reply in the JOINing process.
3250 * Added to USERS command in silcd/command_reply.c to join the client,
3251 we didn't use to know about, to the channel after we've created
3252 a client entry for it. Also, for clienet we did know already still
3253 check whether it is on the channel or not and add it if not.
3255 * Removed silc_server_command_join_notify as the function and its
3258 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3260 * Changed the client's pending command handling to the same as the
3261 server's pending command handling. It is also now possible to
3262 execute command reply functions from other command reply
3263 function as the function callbacks for commands and command
3264 replies are one and same. The pending commands are not static
3265 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
3266 in client connection context. Thus, pending commands are server
3267 connection specific as it is convenient.
3269 Changed the function silc_client_command_pending and
3270 silc_client_command_pending_del and added new function
3271 silc_client_command_pending_check. Removed the
3272 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
3275 * Added cmd_ident, current command identifier, to the client
3276 connection context in lib/silcclient/client.h to keep track on
3277 command identifiers used in command sending. Client's command reply
3278 function handling now supports the mandatory command identifiers.
3280 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
3281 funtions in client to fully support pending command callbacks.
3283 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
3284 as one of the arguments to the application in the command reply
3287 * NOTE: The FORWARDED flag is depracated. It used to be depracated
3288 before first releasing SILC but came back. Now it is removed again
3289 and should come back nomore. The FORWARDED flag was used only
3290 by the JOINing procedure by forwarding the command packet to router.
3291 Now, the JOINing procedure has been changed to more generic (due
3292 to various router environment issues) and FORWARDED is not needed
3293 anymore for anything. The protocol specification is yet to be
3296 Now, removed silc_server_packet_forward from server and the flag
3297 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
3299 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3301 * Renamed NAMES command to USERS command. The NAMES was named that
3302 due to historical reasons. Now it is renamed. Also, rewrote
3303 parts of the USERS command. The nickname list is not sent anymore
3304 by the server. Only Client ID and mode lists are sent in the USERS
3305 command. Changed this also to the protocol specification.
3307 The client now resolves the names and stuff after it receives
3308 the USERS list from the server when joining to the channel.
3310 * WHOIS and IDENTIFY commands has been changed to support multiple
3311 Client ID's per command. One can now search for multiple users
3312 in the network by sending only one WHOIS or IDENTIFY command.
3313 Changed the code and the protocol specifications.
3315 * Removed silc_server_command_identify_parse and changed that IDENTIFY
3316 uses silc_server_command_whois_parse to parse the request. */
3318 * If normal server, do not parse the WHOIS and IDENTIFY requests
3319 before sending it to the router. Saves some time.
3321 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3323 * Fixed JOIN command on client library. Wrong number of arguments
3324 used to crash the client.
3326 * Added silc_server_channel_has_global function to check whether
3327 channel has global users or not.
3329 * Added silc_server_channel_has_local function to check whether channel
3330 has locally connected clients on the channel.
3332 * The silc_server_remove_from_one_channel now checks whether the
3333 channel has global users or not after given client was removed from
3334 the channel. It also checks whether the channel has local clients
3335 on the channel anymore. If it does not have then the channel entry
3336 is removed as it is not needed anymore.
3338 * The silc_server_notify now checks on JOIN notify whether the joining
3339 client is one of locally connected or global. If it is global then
3340 the channel has now global users on the channel and that is marked
3341 to the channel entry. Also, it now saves the global client to
3342 global list who is joining and JOINs it to the channel. This is
3343 for normal server, that is.
3345 Changed silc_server_send_notify_on_channel,
3346 silc_server_packet_relay_to_channel and
3347 silc_server_packet_send_to_channel check if we are normal server
3348 and client has router set (ie. global client) do not send the
3349 message to that client, as it is already routed to our router.
3351 * Implemented LEAVE notify type handling in silc_server_notify
3354 * Tested LEAVE command in router environment successfully. Tested
3355 with two routers, two servers and two clients.
3359 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
3361 * Implemented SIGNOFF notify type handling in silc_server_notify
3364 * silc_server_remove_id now removes the client entry from all channels
3365 it has joined and thusly sends SIGNOFF notify type.
3367 * Rewrote the NAMES list generation in server by removing two excess
3368 loops. The lists are created now inside one loop.
3370 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3372 * silc_server_remove_channel_user checks now also global list
3373 for channel and client.
3375 * silc_server_new_channel_user checks now both local and global
3376 list for channel and client. Fixed a bug in client id decoding.
3377 Used to decode wrong buffer.
3379 * silc_server_channel_message checks now both local and global
3380 list for channel entry.
3382 * Tested channel joining (hence JOIN) in router environment
3383 successfully. Tested with two routers, two servers and two
3386 * Tested channel message sending in router environment successfully.
3388 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Added silc_server_save_channel_key into server.[ch] to save the
3391 received channel key in Channel Key payload processing. It is
3392 also used in JOIN command reply handling.
3394 Equivalent function silc_client_save_channel_key added into
3395 client.[ch] into client library.
3397 * Changed JOIN command reply to send information whether the channel
3398 was created or not (is existing already) and the channel key
3399 payload. Changed protocol specs accordingly.
3401 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
3402 the request was sent by ID and not by nickname. Crashed on
3405 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
3408 now correctly save the received data.
3410 * silc_server_free_sock_user_data now notifies routers in the
3411 network about entities leaving the network.
3413 At the same time implemented functions silc_server_remove_id
3414 and silc_server_send_remove_id to receive and send REMOVE_ID
3415 packets. The packet is used to notify routers in the network
3416 about leaving entities. The ID removed will become invalid in
3419 * Added function silc_idlist_del_server into server. Removes and
3420 free's server entry from ID list.
3422 * silc_server_private_message function now checks, if we are router,
3423 that the destination ID really is valid ID, naturally.
3425 * In router when NEW_ID packet is received (for new client) the
3426 hash of the Client ID is saved in the ID Cache but the
3427 client->nickname is set to NULL, instead of putting the hash
3430 IDENTIFY command now also checks that client->nickname must be
3431 valid. If it is not if will request the data from the server who
3432 owns the client. Added new function
3433 silc_server_command_identify_check.
3435 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
3436 to set the command to already allocated Command Payload.
3438 * Tested private message sending in router environment with two
3439 routers, two servers and two clients. Fixed minor bugs and now
3442 * Fixed segfault from client's NAMES command. Used to crash if
3445 * Forwarded packets must not be routed even if it is not destined
3446 to the receiver. Changed server code comply with this.
3448 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3450 * Added `require_reverse_mapping' boolean value to ServerParams
3451 structure. If TRUE (not default) the server will require that
3452 the connecting host has fully qualified domain name.
3454 If the reverse mapping is not required and hostname could not be
3455 found the IP address is used as hostname.
3457 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3459 * Implemented version string checking to both client and server.
3460 The check is incomplete currently due to the abnormal version
3461 strings used in development version of SILC.
3463 * Changed all command functions in server to use the new
3466 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3468 * Changed char *data to unsigned char *data in ID Cache system to
3469 support binary data as ID Cache data. Changed code to support
3470 binary data in lib/silccore/idcache.c.
3472 * Renamed silc_server_packet_relay_command_reply to
3473 silc_server_command_reply as it is normal packet receiving
3474 function. Rewrote the function to accept command replys for
3475 servers and not only for clients.
3477 * Mark remote router always as registered server if we are connecting
3478 to it. Otherwise, commands sent by the router to us are ignored.
3480 * All ID List find routines now returns the ID Cache Entry pointer
3481 as well if requested.
3483 * WHOIS command works now in router environment, tested with two
3484 routers, two servers and two clients.
3486 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
3487 in router environment (as it is almost equivalent to WHOIS) but
3488 hasn't been tested thoroughly. Added new functions:
3490 silc_server_command_identify_parse
3491 silc_server_command_identify_send_reply
3492 silc_server_command_identify_from_client
3493 silc_server_command_identify_from_server
3495 * Disabled route cache adding because adding two different ID's with
3496 same IP replaces the old cache entry thus giving wrong route.
3497 The entry->router->connection is always the fastest route anyway
3498 so route cache may not be needed. Of course, new routes maybe
3499 established after receiving the ID when the entry->router->connection
3500 might not be anymore the most optimal.
3502 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3504 * Add route cache for received ID for fast routing.
3506 * Added silc_server_packet_route to route received packet on router
3507 that is not destined to us.
3509 * Renamed silc_server_get_route to silc_server_route_get.
3511 * Added id_string and id_string_len fields into SilcServer to
3512 include encoded ServerID for fast comparing without excess
3513 encoding of the ID's.
3515 * Cleaned up WHOIS command on server side. Added following static
3518 silc_server_command_whois_parse
3519 silc_server_command_whois_check
3520 silc_server_command_whois_send_reply
3521 silc_server_command_whois_from_client
3522 silc_server_command_whois_from_server
3524 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
3525 arguments in command replies. All command functions should be
3526 updated to use this macro.
3528 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * Minor typo fixes on command reply handling on server.
3532 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3534 * Added silc_server_command_add_to_channel internal routine to add
3535 the client to the channel after router has created the channel and
3536 sent command reply to the server.
3538 * Added generic silc_server_send_command to send any command from
3541 * Use static buffer with ID rendering instead of duplicating data.
3543 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3545 * Fixed a channel user mode bug when joining to a channel server gave
3546 everybody channel founder rights, oops.
3548 * We mark ourselves as the router of the incoming server connection
3549 if we are router ourselves. This way we can check in some packet
3550 sending functions whether it is locally connected server. For
3551 incoming router connections we put NULL.
3553 * For router sending packets locally means now always sending the
3554 packet cell wide; to local clients and local servers. For normal
3555 server sending packet locally means sending it to only local
3558 * Fixed the JOIN command to really work in router environment. If the
3559 channel is created it is always created by the router. Router is
3560 also responsible of making the initial joining to the channel,
3561 sending JOIN notify to the sending server and distributing
3562 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
3563 does not exist server doesn't do anything else but forward the
3564 command to the router which performs everything.
3566 * Added silc_server_send_channel_key function to send the Channel Key
3569 * Added silc_server_create_channel_key to create new channel key. The
3570 channel key is now re-generated everytime someone joins or leaves
3571 a channel, as protocol dictates. Note: channel->key_len is the
3574 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Splitted server.[ch] finally. Created now packet_send.[ch] and
3577 packet_receive.[ch] to separate packet sending and receiving
3578 routines. The server.[ch] now includes everything else including
3579 actual packet processing (writing and reading data) and other
3582 Renamed silc_server_private_message_send_internal to
3583 silc_server_send_private_message. The routine is still though
3584 used only to relay private messages as server does not send
3585 private messages itself.
3587 Renamed silc_server_new_channel to silc_server_create_new_channel
3588 and added new function sicl_server_new_channel that handles the
3589 incoming New Channel packet. Added also new sending function
3590 silc_server_send_new_channel to send New Channel Payload.
3592 * Added new function silc_server_notify to process incoming notify
3593 packet to the server/router. Server may then relay the notify
3594 to clients if needed.
3596 * Added new function silc_server_new_channel_user to process incoming
3597 New Channel User packet. Router will redistribute the packet and
3598 send JOIN notify to its local clients and locally connected servers
3599 if needed. Normal server will send JOIN notify to its local client
3600 on same channel when received this packet. Added also corresponding
3601 sending function silc_server_send_new_channel_user to sent the
3604 * Added boolean route argument to send_notif_to_channel and
3605 packet_send_to_channel functions to attempt to route the packet
3606 if it is TRUE and send only locally if it is FALSE.
3608 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3610 * silc_server_replace_id now broadcasts the received replace ID
3611 packet if it is not broadcast packet already. The router must
3612 broadcast to inform other routers about changed ID.
3614 * Added backpointer to server's router into SilcServer context in
3615 silcd/server_internal.h.
3617 * Fixed silc_server_packet_broadcast to send correct broadcast
3620 * The channel key is now distributed to the local client as soon
3621 as it is received from the router (in router environment) so that
3622 no other packet may be sent for the channel until client has
3625 * silc_server_remove_channel_user now broadcasts the received
3626 Remove Channel User packet if it is not broadcast packet already.
3627 The router must broadcast to inform other routers about removed
3630 * Added users field into SilcPacketContext that is a reference count
3631 of the context. One can increase the reference count by calling
3632 silc_packet_context_dup which is now changed to just increase the
3633 reference count instead of duplicating the data. The reference
3634 count is decresed by calling silc_packet_context_free that will
3635 free the data after the reference count hits zero.
3637 For now on the packet context and everything allocated into it
3638 (including the raw packet from network) must be freed by calling
3639 the new silc_packet_context_free function. Added also new function
3640 silc_packet_context_alloc that must be used now to allocate the
3641 context. This also means that if a routine is asynchronous from
3642 silc_[client/server]_packet_parse_type the packet context must
3643 be duplicated by calling silc_packet_context_dup. Otherwise it
3644 gets free'd after silc_[client/server]_packet_parse_type returns.
3645 Also, one must remember that if packet is duplicated then its
3646 reference count must be decresed by calling the free function as
3647 many times as it was duplicated.
3649 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
3650 from both client and server.
3652 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3654 * Made joining to a channel working in router environment.
3656 * Cleaned up JOIN command on server side and create function
3657 silc_server_command_join_channel internal routine to make the
3660 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3662 * Changed silc_command_pending list to SilcDList. Also, added
3663 `ident' field to SilcServerCommandPending structure to identify
3664 the reply and to call correct callback.
3666 Added silc_server_command_pending_check function to replace the
3667 corresnponding macro. The silc_command_pending list is not
3670 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
3671 to set identifier to previously allocated Command Payload. It
3672 is used to set identifier for command when resending Command
3675 * Added silc_command_payload_encode_payload to encode Command
3676 Payload buffer from SilcCommandPayload structure.
3678 * Added silc_argument_payload_encode_payload to encode Argument
3679 payload buffer from SilcArgumentPayload structure.
3681 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3683 * Changed WHOIS command to support router connection on server side.
3684 The whois request is always sent to router unless the server is
3685 standalone server. After server has received the reply from the
3686 router will it send the reply to the client.
3688 * Added silc_server_packet_broadcast into silcd/server.[ch] to
3689 broadcast received broadcast packet. The function is used only
3690 by router. The broadcast packet is always sent to the router's
3693 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
3694 render given ID to printable string, for log files for example.
3696 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3698 * Made basic router to router connections working. At least they
3699 can now connect to each other but nothing really works the way
3700 they are supposed - yet.
3702 * Added new initiator token to RouterConnection configuration
3703 file in silcd/serverconfig.[ch]. It is used to tell whether we
3704 are the initiator to the remote router or whether we'll expect
3705 the other end to connect.
3707 * Moved registering of listener task to silc_server_init, hence
3708 the server starts listenning as soon as it is run, even if it
3709 does not have connections to other routers. Let's see how well
3712 * Changed default connection retry timeouts for more suitable in
3715 * Removed cipher and such arguments from silc_idlist_add_client
3716 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
3717 Added new function silc_idlist_add_data to add the keys and stuff
3720 * Added SilcIDListData structure and added it to SilcClientEntry
3721 and SilcServerEntry as their first field in the structure. This
3722 way we can explicitly cast the ID entries to the SilcIDListData
3723 structure and get common data for the entries. In past, we had
3724 to first check what type of connection it is and then cast it to
3725 correct ID entry type. Now, we can directly cast the opaque
3726 pointer to the SilcIDListData (no matter what ID entry it actually
3727 is) and get the data needed.
3729 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3731 * Wow, found a bug in scheduler. The scheduler uninitialized itself
3732 in some circumstances even if threre were timeout tasks, though not
3733 IO tasks, but tasks anyway. Now fixed.
3735 * Defined SilcServerConnection structure to hold connection specific
3736 stuff about directly connected servers and routers. The definition
3737 is currently in silcd/server_internal.h. I thought about having
3738 a bit more important role fro this struct but for now it is used
3739 only when connecting to other server (or router actually).
3741 * Added connecting retry support in server when connecting to
3742 router(s). The retry feature implement exponential backoff
3743 algorithm. Also, added SilcServerParams structure to hold default
3744 parameters for server. For now, it include these retry settings
3745 and are hard coded. After server is moded to be as Silc Server
3746 Library this structure will be more important.
3748 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3750 * Changed client librarys channel->clients table to SilcList and
3751 changed code accordingly.
3753 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * Changed client's channel table to SilcList and changed code
3756 accordingly. Also changed SilcChannelClientEntry to include back-
3757 pointer to the channel so that client entry can use that structure
3758 as list as well and we have fast cross-reference to the channel.
3759 This change dramatically decreased the complexity of channel
3760 handling with client entry and vice versa (removed one extra
3761 loop when searching for channel entry from many functions).
3763 * Changed server->sim from table to SilcDList and changed code
3766 * NAMES command can now be used from user interface. It will show
3767 the user list on the channel, neatly.
3769 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
3770 Code now saves realname of the user if it becomes available.
3772 * Renamed configure.in to configure.in.pre and made ./prepare
3773 script to automatically add correct version string to
3774 configure.in which it creates from configure.in.pre.
3776 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3778 * NAMES command reply now shows users mode with the nickname when
3781 * Moved silc_client_ch[u]mode[_char] functions from
3782 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
3783 place sucks, they are utility functions and should be in some
3786 * Fixed some unsigned int's to unsigned short's. Patch by cras.
3788 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
3791 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3795 * Added TRQ (efficient deque and list library) into lib/trq. This is
3796 a very good list library that is currently used in the SILC. Defined
3797 SilcList API over the library because I didn't like the API very
3798 much. See lib/trq/silclist.h for the API and examples of how to
3799 use the API. Fixed various places in the code to use the new
3800 SilcList API. The SilcList is meant for lists that has a structure
3801 already defined as a list. It is not suitable to add just some
3802 context to the list (in TRQ, the context is the list actually).
3804 So, I defined SilcDList that can be used for the purpose where
3805 predefined list structure does not exit. This can be used as
3806 such list. Now some context just can be added to the SilcDList.
3807 Currently this list is not used in the SILC just yet, though there
3808 are a lot places where this can replace dynamically allocated
3809 tables and I will fix these places, later, to use SilcDList.
3810 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
3811 and use TRQ internally).
3813 Also fixed some annoying warning messages that the original TRQ
3814 code generated. Also minor changes to TRQ's Makefile.in.
3816 * Added support for querying by Client ID to both WHOIS and
3817 IDENTIFY commands into server, as required by the protocol.
3819 * Removed method function pointers from SilcBuffer structure. They
3820 weren't used to anything and just increased the context size for
3821 no good reason. This change also made silc_buffer_alloc and
3822 silc_buffer_free functions inline functions.
3824 * Disabled command flooding detection support until it's fixed so
3825 that it accepts commands in but does not execute them more than once
3828 * Added silc_net_localhost(), to return local hostname, into
3829 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
3830 that must be initialized before calling silc_client_init.
3832 * Added new function: silc_server_send_notify_on_channels to send
3833 notify messages to all channels client has joined. It is assured
3834 that the message is sent only once per client.
3836 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
3837 lib/silcutil/silcutil.[ch] as silc_format function. The new
3838 function is generic and is used by server as well, not only by
3839 the logging routines.
3841 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
3842 the provided version string was not acceptable. Added new function:
3843 silc_ske_check_version into lib/silcske/silcske.h. The function
3844 must be implemented by the application (client or server) and it
3845 does not reside in the SKE library. The function checks the version
3846 string remote end sent.
3848 * Added back pointers (to opaque context and to SilcSocketConnection)
3849 into SilcPacketContext structure into lib/silccore/silcpacket.h.
3851 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
3852 duplicate packet context structure.
3854 * Changed `notify' client operation to send same arguments as client
3855 receives from server except for ID's. ID's are mapped to correct
3856 ID entry and that is returned. Also, if channel entry is not sent
3857 by server but the notify is for channel the channel entry is sent
3858 to application (otherwise application doesn't know that it is for
3859 channel (library gets it from packet's Destination ID)).
3861 * Added silc_client_remove_from_channels into client library to
3862 remove a client from all channels it has joined to. Used when
3863 received SIGNOFF notify from server. Added also new function
3864 silc_client_replace_from_channels to replace old ID entry with
3865 new ID entry on all channels. Used when received NICK_CHANGE
3868 * Fixed ID Cache list handling in silc_idlist_get_client in
3869 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3870 to get (or query) client by ID.
3872 * Updated TODO list.
3874 * Added connection authentication status message defined by the
3875 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3876 support for these into the code in client and server side.
3878 * Added generic function silc_client_send_command to send any command
3879 with variable argument list. Application should use this function
3880 to send commands if the command functions provided by the library
3881 does not suite for the application's user interface needs.
3883 * Added new `failure' client operation. Application is notified about
3884 received failure packet if client is executing a protocol. In this
3885 case the protocol's execution has failed.
3887 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3888 is required by the protocol.
3890 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3891 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3894 * Added status flag to SilcSKE object to indicate realtime status
3895 of the SKE protocol.
3897 * Application receives now exactly same command reply arguments as
3898 the library receives from server. However, if ID is received the
3899 corresponding ID entry is returned to the application (eg. Client
3900 ID is mapped to correct SilcClientEntry entry and that is returned).
3901 Changed command_reply client operation due to this change.
3903 * Changed all ID's in commands and in command replys as ID Payloads.
3904 Change affected both client and server side codes.
3906 All ID's sent in SILC network (with execption of ID's in SILC
3907 Packet header) are sent in ID Payload to support variable length
3910 * Server now notifies nick changes and notifies all clients on
3911 the channels about the new nickname (about the new Client ID,
3914 * Implemented CMODE command to change channel modes. Supports all
3915 channel modes defined by the protocol specs except ban and invite
3916 lists. (Also, private channel key mode is supported but support for
3917 setting private channel key in client is missing, thus, this mode
3918 has no effect on client side (except that server requires that the
3919 client uses private channel key and normal channel traffic does not
3922 Also, invite mode works per se, but INVITE command does not work
3923 yet correctly, so you can set channel as invite only channel but
3924 inviting clients to the channel does not work (it is yet to be
3925 thought what's the best way to do it).
3927 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3928 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3929 Implemented CUMODE command to change user's mode on the channel.
3930 Supports all modes defined by the protocol specs.
3932 * Added NAMES command reply to return users modes on the channel.
3934 * Removed unnecessary and slow ciphers from lib/silccrypt.
3936 * Set SO_KEEPALIVE option to connection sockets by default.
3938 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3940 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3941 redefined the Notify Payload into protocol specs.
3943 * Added silc_id_payload_parse_id to get ID directly from raw
3946 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3949 accept searching by Client ID as well.
3951 * Added support for LEAVE and SIGNOFF notify types in client library.
3953 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3954 to parse ID Payload from raw data.
3956 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3958 * Added flags parameter into silc_ske_assemble_security_properties
3959 function in lib/silcske/silcske.[ch].
3961 * Changed notify client operation to fit better for notify messages
3962 sent by server. The notify payload received from server is now
3963 passed to the application (after parsing it to SilcNotifyPayload).
3964 It is application's responsibility to retrieve the arguments
3965 from the payload and show the message the way it wants. The message
3966 sent by server is implementation specific.
3968 * Changed public keys to comply with the protocol specification.
3969 Old public keys are not supported anymore and are not compatible.
3971 * Removed nickname from Channel Payload as the latest draft removed
3972 it. The client must resolve the nickname from the NAMES command
3973 reply received when it joined the channel.
3975 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3977 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3979 * Fixed some errors in protocol specification drafts.
3981 * Created lib/silccore/silcnotify.c to implement Notify Payload
3982 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3983 generic payloads described by protocol specifications. The file
3984 includes implementations for ID Payload and Argument Payload.
3986 * Changed Command Payload implementation to use the new Argument
3987 Payload. Changed command_xxxx_payload to command_payload_xxxx
3988 to comply with SILC coding conventions.
3990 * Added suppport for Argument Payload handling in Notify Payload
3991 implementation as protocol requires it. Added the new support
3992 into server and client lib as well.
3994 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3996 * Added support for multiple nicknames on same channel. [n] is
3997 added locally to the nickname if there are more than one same
3998 nicknames on the channel.
4000 * Server now sends all nicknames that matched WHOIS request.
4001 Client also shows the list received from server.
4003 * Added TOPIC command to client side. User can now set and show
4004 current topic on channel.
4006 * Added MOTD command to client and server. Also, server sends the
4007 motd when client connects to the server.
4009 * Changed version strings to comply ISO 8601.
4011 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * Fixed protocol error handling in client library. It should now
4014 cope even if the SKE fails for some reason.
4016 * Made new protocol specification drafts for submitting to IETF.
4018 * Implemented TOPIC command to server in silcd/command.c.
4020 * Added two new notify types into lib/silccore/silcnotify.h:
4021 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4022 notify nickname change and topic setting/change on a channel.
4024 * API change of command_reply operation in client library. The
4025 application gets now the status type received from server as well.
4027 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4029 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4031 * Cras fixed and optimized the packet handling even further and
4032 it should work now. Minor change to the prototype of function
4033 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4035 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4037 * Added new function into lib/silcutil/silcschedule.[ch]:
4038 silc_schedule_with_fd to select() a specified fd. The function
4039 returns after timeout expires or data arrives or goes. The
4040 function is used by packet routines to wait that all data is
4041 received from network.
4043 * Fixed data reading from network in lib/silccore/silcpacket.c.
4044 The code now assures that all data is read from the fd and then
4045 continues packet processing. This was a bug fix since the code
4046 used to drop some data in some circumstances.
4048 * Added new function into lib/silcclient/client.[ch]:
4049 silc_client_start_key_exchange to start key exchange after
4050 connection has been established to server. The code internally
4051 now uses this funtion but its main purpose was to provide it
4052 for applications that perform their own connecting. After
4053 application has created a connection it merely calls this
4054 function to start the key exchange between client and server.
4055 The library takes care of everything else after that.
4057 Updated also lib/silcclient/README to explain the usage of
4060 * Do not send to application information that connection has
4061 been established. Application gets notified it by connect
4064 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4066 * Applied cras's patch to add silc_schedule_one function. The
4067 function runs scheduler once and returns.
4069 * Fixed the scheduler after cras messed it up. The timeout
4070 handling works now as it's supposed to work.
4072 * Added into lib/silccore/ silcnotify.h to include notify
4073 message types support. Changed silc_server_send_notify*
4074 functions, in server.[ch], to support those new notify types.
4075 Added the support for the notify types into client library,
4076 as well. Added new notify client operation into ops.h in
4079 * Changed silc_server_packet_send_to_channel to send normal
4080 packets instead of just channel message packets. The function
4081 is now used to send the notify packets to channels. It is not
4082 used to send channel message packets anymore, as server never
4085 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4086 va_arg()s as it seems to require it nowadays. I guess, if SILC
4087 is compiled with older va_arg() the new code should work anyway.
4089 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Splitted core library. Core library (lib/silccore) includes
4092 now only SILC protocol specific core (and common) components.
4093 Created new utility library (lib/silcutil) that includes more
4094 generic purpose stuff. The stuff for util library was taken
4095 from the old core library. This was minor and easy split.
4097 * Created SILC Client Library (lib/silcclient) that includes
4098 implementation of the SILC client without user interface. This
4099 was major move from silc/ directory. The code has been changed
4100 so that it is transparent towards the user interface. The
4101 silc/ directory includes now the same user interface as before
4102 and it uses the new client library. Read lib/silcclient/README.
4103 Basicly, the client library performs everything else related
4104 to SILC except user interface handling. Also, configuration
4105 files are considered to be part of user interface and library
4106 does not handle them.
4108 This change also changed a lot of structures, function naming etc.
4109 Most important change was that SilcClientWindow object was
4110 renamed to SilcClientConnection in the client library. Created
4111 also new file lib/silcclient/ops.h. Also added new files
4112 silc/local_command.[ch] and silc/client_ops.[ch].
4114 All these changes were made to make it easier for user interface
4115 designers to create what ever user interface for the SILC client
4118 It is also expected that the server will be moved to lib
4119 directory as well and SILC Server Library will be created;
4120 sometimes in the future.
4122 * Removed Local commands from lib/silccore/silccommand.h as
4123 they are application specific and new client library does not
4124 handle any of those anymore.
4126 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4127 old client implementation in silc/.
4129 * Added support for callback functions in SILC_LOG_* macros.
4130 Application can now set its own callbacks that will be called
4131 instead of using the default functions that will always print
4132 the debug messages to stderr (or stdout). Also, debugging can
4133 now be disabled by setting silc_debug to FALSE and re-enabled by
4134 setting it to TRUE. Note, that logging will still work even
4135 if debugging is disabled.
4137 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4138 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4139 silc_log_reset_debug_callbacks.
4141 * To enable debugging in silc client one must give now -d
4142 option on command line.
4144 * Changed silc_schedule_init to automatically allocate task queues
4145 if they are not allocated before calling it.
4147 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4149 * Added GMP 3.1 into math library.
4151 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4153 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4154 a channel in SILC network. The packet is used by servers and
4155 routers to notify other routers that user has left a channel.
4156 This little feature was missing until now. Added the feature
4157 to protocol specification as well.
4159 Added functions: silc_server_send_remove_channel_user and
4160 silc_server_remove_channel_user into server.[ch].
4162 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4163 lib/silccore/silcpacket.h. However, they are not implemented
4166 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Fixed joining to a channel and sending channel messages
4169 between server and router. The channel message sending should
4170 now work inside a cell.
4172 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4174 * Fixed the private message sending between server and router.
4175 The private message sending should now work inside a cell.
4177 * Added silc_server_replace_id into server.[ch] to replace
4178 existing ID in the SILC network.
4180 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4181 and silc_idlist_replace_server_id into idlist.[ch] in server.
4183 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Fixed the server to server connections. Server can again now
4186 connect to router. Router to router connections probably does
4189 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4191 * Added dynamic protocol registering support. Now protocols can
4192 registered and unregistered on the fly. Patch by cras.
4194 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4196 * Added lib/contrib directory to hold routines that some platforms
4197 don't have but are needed by SILC.
4199 * Added getopt.c, getopt1.c and getopt.h from GNU C library
4200 into lin/contrib to provide getopt() and getopt_long() for
4201 those who don't have it.
4203 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Added AWAY command to client. When away message is set and
4206 client receives a private message packet the client automatically
4207 replies to the sender with the away message.
4209 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
4210 bug seemed to be the cause of recent problems when compiling
4213 * Added version detection support to SKE protocol specification
4214 and added the new changes to the SKE implementation as well.
4215 There were other minor changes in the SKE protocol as well.
4217 Many changes in lib/silcske/silcske.[ch] and in
4218 lib/silcske/payload.[ch].
4220 * Added ^U functionality, clear input line. Patch from cras.
4222 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4224 * Mainly small bugfixes on core library. Fixed some debugging
4225 logging and buffer overflow in silclog.c.
4227 * Updated config.sub and config.guess on the distribution tree.
4229 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4231 * Added command lagging support in server. Client may execute
4232 commands now only once in two seconds.
4234 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4236 * Optimized packet reception. MAC computation and checking is now
4237 also more optimized. A lot previously duplicated code is now
4238 used as generic by both client and server.
4240 * Fixed key pair generation in clientutil.c
4242 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Added into lib/silccore/silcbufutil.[ch] new function;
4245 silc_buffer_realloc.
4247 * Moved generic packet sending/encryption functions to
4248 lib/silccore/silcpacket.[ch] from client and server. Some
4249 rewriting of the functions.
4251 * Moved all generic packet reception/decryption functions to
4252 lib/silccore/silcpacket.[ch] from client and server. The
4253 packet processing is now much cleaner in both client and server.
4254 These were major changes in both client and server.
4256 * Created many common functions in server to do packet sending.
4257 Previously code were duplicated a lot, this has been removed
4260 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4262 * Rewrote major parts of the ID cache system. Don't know
4263 whether it is better now or not but at least the API is more
4266 * Major rewrite on ID cache stuff on client because of the ID
4267 cache API changes. Added idlist.c to client.
4269 * Also major rewrite on ID cache stuff on server as well.
4270 Major rewrite of idlist.[ch]. SilcXXXList's are now named
4271 SilcXXXEntry's. We won't keep anymore idlist specific pointers
4272 in hand, instead they are all put into the ID cache system now.
4273 All server_idlist_* routines uses ID cache now instead of
4274 traversing its own lists (those lists does not exist anymore).
4275 SilcIDList though still exists. Also, SilcXXXEntry's are
4278 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4280 * Finally made the SKE implementation compliant to the protocol
4281 specification. All mp integers are now binary encoded as
4282 opposed being HEX encoded.
4284 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
4287 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
4288 functions: silc_[encode/decode]_pem. Also added function
4289 silc_encode_pem_file to PEM encode with newlines ('\n') for
4292 * SILC public keys are now encoded either PEM or binary. Same
4293 option is for private keys as well. By default private keys
4294 are binary encoded and public keys PEM encoded. Silly HEX
4295 encoding were removed.
4297 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
4298 function to create fingerprints.
4300 * Fixed a bug in SHA1; does not change the original data anymore.
4302 * Partly implemented INFO command on client and server side.
4303 Fixed CLEAR command. Changes to SERVER command; show current
4304 server(s) when giving command without arguments. Added
4305 VERSION command to client.
4307 * Added check to server that unregistered connections cannot
4308 execute commands (unless it is specificly allowed).
4310 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * Fixed screen refresh.
4314 * Fixed channel joining bug from client. On some circumstances
4315 client tried to join to a channel it had already joined.
4317 * Added public key verification process into client's protocol.c.
4318 The client now verifies the public key from user and saves
4319 it into ~./silc/serverkeys/ directory.
4321 Added into: clientutil.[ch]: silc_client_verify_server_key.
4323 * Changed SKE protocol's silc_ske_initiator_finish function
4324 to accept callback function that verifies the received public
4325 key. Removed old silc_ske_verify_public_key function.
4327 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4329 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
4330 silc_pkcs_private_key[_data]_set.
4332 * Made the password and public authentication more cleaner in
4333 server's protocol.c.
4335 * Removed historic and obsolete protocol `channel_auth' from
4336 both client and server.
4338 * Removed wrong way of sending command status messages from
4339 server to client in server's command.c. The old way violated
4340 protocol specification.
4342 Changes to silccore/silccommand.[ch]: removed
4343 silc_command_encode_status_payload -> not needed anymore,
4344 changed silc_command_encode_payload_va to accept extra
4345 argument on variable argument list. The argument type must
4346 now be provided to the function. Also, added new function:
4347 silc_command_encode_reply_payload_va which is same as
4348 normal command_encode_payload_va except command status type
4349 is provided as extra argument.
4351 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4353 * Added ~./silc directory handling. The directory includes the
4354 public and private keys for the client.
4356 Added silc_client_check_silc_dir, silc_client_create_identifier
4357 and silc_client_load_keys.
4359 * Implemented SILC protocol compliant public key. Added public
4360 and private key saving to and loading from files.
4362 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
4363 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
4364 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
4365 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
4366 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
4368 Implemented: silc_pkcs_save_[public/private]_key[_data] and
4369 silc_pkcs_load_[public/private]_key.
4371 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4373 * Added silc_server_get_route (route.[ch]) to get connection
4374 data for the fastest route for given ID.
4376 * Implemented INVITE command on client and server. The command
4377 were re-defined in the SILC Protocol Specification and the
4378 implementation now complies with the specification.
4380 * Implemented PING command on client and server.
4382 * Implemented NAMES command on client and server. The server side
4383 supports currently only normal server not router server yet.
4384 Some changes to NAMES definition in SILC protocol specification.
4386 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4388 * Implemented LEAVE command on client and server.
4390 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
4391 again. This change was made to the protocol as well. Server
4392 should not violate the protocol specification anymore.

4396 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
4397 was tested. SOCKS4 was not but should work anyway.
