1 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Do not show the private channels on the WHOIS channel list
4 as it is not allowed by the protocol. The affected file is
7 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
9 * Assure that the packet length digged from the actual packet
10 is something sensible in the silc_packet_decrypt_rest_special
11 in lib/silccrypt/silcpacket.c.
13 * Free and NULL the allocated pointer in silc_hmac_alloc if
14 the HMAC allocation fails. The affected file is
15 lib/silccrypt/silchmac.c.
17 * Print the selected security properties to the log files in
18 the server. Affected file silcd/protocol.c.
20 * Add SKE's reference counter even if calling the completion
21 callback manually. Otherwise it goes negative, although it
22 does not cause any problems. The affected file is
23 lib/silcske/silcske.c.
25 * Remove the client entry with short timeout after giving the
26 KILL command. Affected file lib/silcclient/command.c.
28 * Fixed to send error reply in WHOIS and IDENTIFY commands in
29 case all found clients are already disconnected (WHOWAS would
30 found them) in the server. Affected file silcd/command.c.
32 * Update the last_receive (time of last data received) to be
33 updated only when received private or channel message so that
34 the idle time showed in WHOIS makes more sense.
36 * Added boolean field `valid' in to the SilcClientEntry in the
37 client library to indicate whether the entry is valid or not.
38 This fixes the nickname change bug on channel when changing
39 the nickname to be same than the old (like nick to Nick) the
40 nickname formatter doesn't set the new nick anymore to Nick@host.
41 Affected file lib/silcclient/idlist.[ch].
43 * Now actually fixed the nickname changing on disconnection.
44 Added new function silc_change_nick to the Irssi SILC Client.
45 Affected file irssi/src/silc/core/client_ops.c,
46 irssi/src/silc/core/silc-nicklist.[ch].
48 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
50 * Check that the public key exists in the GETKEY command before
51 trying to encode it. Affected file silcd/command.c.
53 * Print some notifications on received public keys with GETKEY
54 command in the Irssi SILC Client. Affected files are
55 irssi/src/fe-common/silc/module-formats.[ch],
56 irssi/src/silc/core/client_ops.c.
58 * Use IDENTIFY command to resolve the server information in the
59 GETKEY command instead of INFO command. Affected file
60 lib/silcclient/command.c.
62 * All command reply functions in the client library now calls
63 the pending command reply callbacks even if an error has
64 occurred. The server has done this a long time and now it was
65 time to move the client library to this as well. Now all
66 errors can be delivered back to the pending command reply
67 callbacks if necessary. Affected files are
68 lib/silcclient/command[_reply].[ch].
70 * Change the nickname on disconnection back to the username
71 because in reconnect the server will enforce it to it anyway.
72 Affected file irssi/src/silc/core/silc-servers.c.
74 * Fixed a config file parsing bug in the Irssi SILC client.
75 Affected file irssi/src/silc/core/clientconfig.c.
77 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
79 * When printing the channel mode on JOIN, verify that the
80 channel key and channel's HMAC are valid. Affected file
81 irssi/src/silc/core/client_ops.c.
83 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
85 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
86 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
87 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
89 * Removed channel key rekey task deleting from the function
90 silc_server_save_channel_key. Affected file silcd/server.c.
91 Added explicit timeout task context instead that is used to
92 delete the task if we are registering a new task before the
95 * When channel key rekey occurs the client library now saves
96 the old channel key for a short period of time (10 seconds) and
97 is able to use it in case some is still sending channel
98 messages encrypted with the old key after the rekey. Affected
99 file lib/silcclient/[idlist.h|client_channel.c].
101 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
103 * Added check to the silc_server_new_id_real to not accept
104 new ID if it is the sender's own ID. Affected file is
105 silcd/packet_receive.c.
107 * Assure that we do not announce ourself or the one we've
108 sending our announcements when we're router and are announcing
109 servers to our primary router. Affected file silcd/server.c.
111 * Fixed silc_server_command_identify_check_client to assemble
112 correct WHOIS packet. It send corrupted WHOIS packet and
113 caused problem with router to router connections. Affected
114 file silcd/command.c.
116 Fixed also silc_server_command_whois_check the same way
117 as for the IDENTIFY command.
119 * Added new SilcIDListStatus to the server in the SilcIDListData
120 structure. The status now includes the current status of
121 the entry (like registered, resolved etc.). Affected file
122 silcd/idlist.[ch]. Defined a bunch of different status types
123 as well. This replaced the old boolean registered field as well.
125 Added resolve_cmd_ident field to the SilcClientEntry structure
126 too so that if the entry is for example being resolved so
127 another command may attach to the same pending command reply
128 without requiring to resolve the same entry again. This concept
129 should optimize the WHOIS and the IDENTIFY resolving under
130 heavy load by taking away unnecessary resolving for entries
131 that are being resolved already.
133 Added support for adding multiple pending commands for one
134 command idenfier. Affected file silcd/command[_reply].[ch].
136 * Fixed WHOIS and IDENTIFY save to remove the cache entry
137 before deleting the data. Otherwise the hash table will have
138 freed data in comparison functions. Affected file is
139 silcd/command_reply.c.
141 * Fixed silc_idlist_replace_client_id to add the new entry to
142 the cache with NULL nickname. Otherwise there will be invalid
143 memory as the nickname after the nickname is freed. Affected
144 file silcd/packet_receive.c.
146 * Fixed the silc_idlist_get_clients_by_hash. The entries was
147 saved into wrong slots because the previous number of entries
148 was not taken into account. Affected file silcd/idlist.c.
149 Fixed same thing in silc_idlist_get_clients_by_nickname too.
151 * If we are router and we receive JOIN notify to a channel that
152 does not have any users then notified client is marked as the
153 channel founder, as it is it. The affected file is
154 silcd/packet_receive.c
156 * Added to the extended hash table API's table_del_*ext functions
157 the destructor as argument too, so that the caller can decide
158 which destructor to use or whether to use destructor at all.
159 Affected file lib/silcutil/silchashtable.[ch].
161 * Fixed ID Cache purging. It actually deleted the entries from
162 the hash table after the data was freed. The hash table ended
163 up comparing freed memory. The affected file is
164 lib/silccore/silcidcache.c.
166 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
168 * Fixed Irssi SILC client's KILL command's HELP syntax.
170 * The USERS command now resolves the detailed user information
171 if the userinfo field is missing. Affected file is
172 lib/silcclient/command_reply.c.
174 * Do not print error in silc_file_read if the read file does
175 not exist. Just silently return NULL. Affected file is
176 lib/silcutil/silcutil.c.
178 * Fixed the silc_log_output to not wine about NULL filename
179 and to not create some bogus " " filename. Affected file is
180 lib/silcutil/silclog.c.
182 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
184 * Fixed various printing bugs on the user interface in the
185 Irssi SILC Client. Minor changes that were forgotten from
188 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
190 * Fixed the configure.in.pre and the compilation and distribution
191 environment to support the new autoconf 2.52. That version is
192 now required to compile the CVS trunk.
194 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
196 * Renamed function silc_parse_nickname to silc_parse_userfqdn
197 to generally parse user@fqdn format strings. Affected file
198 lib/silcutil/silcutil.c.
200 * Added nickname_format and nickname_force_format fields to the
201 SilcClientParams structure. The first one defines the format
202 for the nicknames that the library will enforce if the receives
203 multiple same nicknames. The second one is boolean value and
204 can be used to force the library to always enforce the format
205 to the nicknames regardles whether there are multiple nicknames
206 or not. This configurable formatting was employed to flexibly
207 support accessing multiple nicknames from the user interface.
208 The userinterface can now set the nicknames to what ever format
209 they prefer. Affected file lib/silcclient/silcapi.h.
211 Added function silc_client_nickname_format to the file
212 lib/silcclient/idlist.c. It performs the nickname formatting.
214 Added new field `hostname´ to the SilcClientEntry context.
215 It holds the hostname of the client. Affected file is
216 lib/silcclient/idlist.h.
218 * Irssi SILC Client sets the nicknames in nick@hostn format.
219 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
220 irssi/src/silc/core/silc-core.c.
222 The WHOIS printing now also shows both the real nickname and
223 the formatted nickname so that user knows how to access the
224 user if there are multiple same nicknames cached. Affected
225 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
226 printing formatting too to take the hostname now as a separate
227 argument. The Affected file is
228 irssi/src/fe-common/silc/modules-formats.[ch].
230 * Changed the silc_client_get_clients_local to accept the formatted
231 nickname as argument. It accepts the real nickname too but the
232 formatted nickname can be used to find the true entry from
233 multiple entries. Affected file lib/silcclient/silcapi.h and
234 lib/silcclient/idlist.c.
236 * Added nickname_format_parse field to the SilcClientParams.
237 It is a callback function provided by the application to parse
238 the nickname out of the formatted nickname string. The library
239 calls it to get the nickname from the formatted string. Since
240 the application generally knows better the format of the nickname
241 string it parses it instead of the library, even though library
242 encodes the formatted string. If the callback function is not
243 provided then the library will use the string as is. The
244 affected file is lib/silcclient/silcapi.h.
246 * All the nickname strings passed to the client library in
247 commands are now expected to be formatted nickname strings.
248 If the command does not support the formatted nickname string
249 it will assume that the sent string is the actual nickname.
250 Affected file lib/silcclient/command.c.
252 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
254 * Added public key authentication support to OPER and SILCOPER
255 commands in the client library. Affected file is
256 lib/silcclient/command.c.
258 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
260 * Changed the get_auth_methdod client operation to be asynchronous.
261 It can be async if the application resolves the authentication
262 method from the server during the negotiation. Added new
263 SilcGetAuthMeth completion callback that the application will
264 call after resolving the authentication method.
266 Added function silc_client_request_authentication_method that
267 the application can use to resolve the authentication method
268 from the server. Added also SilcConnectionAuthRequest callback
269 that the library will call after the server has replied. The
270 application can call this function if it does not know the
271 current authentication method.
273 Affected files are lib/silcclient/client.c and
274 lib/silcclient/silcapi.h.
276 * The Irssi SILC client now automatically resolves the authentication
277 method incase any configuration information is not present (and
278 currently there never is). The affected file is
279 irssi/src/silc/core/client_ops.c.
281 * Fixed public key authentication from the client library.
282 Affected file lib/silcclient/protocol.c. Changed also the
283 protocol specification about the public key authentication in
284 the connection authentication protocol. The actual data to be
285 signed is now computed with a hash function before signing.
287 * Fixed the public key authentication from the server as well.
288 Affected file silcd/protocol.c.
290 * Removed the mlock()'s from the memory allocation routines.
291 Affected file lib/silcutil/silcmemory.c. The ./configure does
292 not check anymore for the mlock(). Affected file is
295 * Fixed USERS command in server to allow the execution of the
296 command for private and secret channels if the client sending
297 the command is on the channel. Affected file silcd/command.c.
299 * Fixed silc_client_get_clients_local to return the clients
300 count correctly. It could return wrong value. Affected file
301 lib/silcclient/idlist.c.
303 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
305 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
306 types. The assembler optimizations seemed not to like 64-bit
307 data types. The assmebler optimizations thus are now enabled
308 also for BSD systems as opposed to only enable them for Linux.
310 * Do not check for threads at all on BSD systems. Affected
311 file configure.in.pre.
313 * Removed -n and -h options from the Irssi SILC Client since
314 they are not used in silc.
316 * Fixed the prime generation to assure that the first digit
317 of the generated random number is not zero since our conversion
318 routines does not like number strings that starts with zero
319 digit. If zero digit is seen the random number is regenerated.
320 This caused some corrupted RSA keys when the zero first digit
321 was met. Affected file lib/silcmath/silcprimegen.c.
323 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
325 * Fixed WIN32 configuration in the ./configure script.
326 Fixed to include xti.h on environments that has it.
327 Patches by Carsten Ilchmann and andrew.
329 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
331 * Changed the silc_id_create_client_id to be collision
332 resistant. It is now assured that there cannot be created
333 two same client ID's. I suspect that some weird bugs in
334 the server were actually caused by duplicate Client IDs.
335 Affected file silcd/serverid.[ch]. A router receiving
336 new ID now also assures and informs the sending server
337 if the ID caused collision.
339 * Changed the silc_id_create_channel_id to also assure that
340 there are no collisions.
342 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
344 * Statement about ignoring the Mutual Authentication flag when
345 performing rekey with PFS was a bit misleading. It is ignored
346 if it was set in the initial negotiation, it cannot be even
347 set in the rekey. Fixed in the ke-auth draft. Started the
348 new versions of the protocol drafts in the doc/.
350 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
352 * Fixed a bug in silc_client_command_identify_save when saving
353 new channel information. The channel name was no duplicated
354 and caused crash on exit. Affected file is
355 lib/silcclient/command_reply.c.
357 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
359 * Fixed the getkey command handling in the server. Send just
360 empty OK reply to the sender if the key could not be fetched
361 (but everything else was ok, like the key just was not available).
362 Changed the public key parameter to optional in the protocol
363 specs so that empty OK reply can be sent. Affected file
366 Added a message to Irssi SILC client to tell to user if the
367 server did not return a public key.
369 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
371 * Fixed a channel key regeneration bug. It registered new
372 timeout tasks exponentially until all system resources were
373 used. Affected file silcd/server.c.
375 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
377 * Added the SILC Document generator to the scripts/silcdoc.
378 It can be used to generate the Toolkit Reference Manual out
379 of the source tree. Internally it will also use the RoboDoc
380 generator now imported in util/robodoc.
382 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
384 * Added couple of return's in rekey protocol if error orccurred
385 during the protocol. The execution must be terminated.
386 Affected file silcd/protocol.c. Also, terminate the protocol
389 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
391 * The client's Client ID was created initally from the wrong
392 nickname (it could have been in format nick@host) in the
393 silc_server_new_client. Affected file silcd/packet_receive.c
395 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
397 * Added some SILC_LOG_ERROR's to various error conditions
398 if client could not be added to ID cache. Affected files
399 silcd/packet_receive.c and silcd/server.c.
401 * When client's sock->user_data is freed, NULL also the
402 client->router and client->connection pointers. Added check
403 for these pointers being NULL to various places around the
404 code. Affected file silcd/server.c.
406 * Added client->data.registered == TRUE checks to various
407 places around the code to assure that unregistered client's
408 are not handled when it is not allowed. Affected file
411 * Added `bool registered' fields to all
412 silc_idlist_[server|client]_get_* routines to indicate whether
413 the fetched client needs to be registered or not. Affected
414 file silcd/idlist.[ch].
416 * Add your own entry as registered to the ID cache in the
417 server. Affected file server.c.
419 * Fixed a bug in silc_server_new_server. The SilcServer was
420 set as the new server's context instead of SilcServerEntry.
421 This naturally caused some weird bugs.
423 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
425 * Do not delete the channel rekey task when adding it
426 for in silc_server_create_channel_key.
428 * Changed the silc_server_create_channel_key to return
429 TRUE or FALSE to indicate the success of the channel key
432 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
434 * Fixed MSVC++ project files and added missing files to
435 Makefiles under win32/.
437 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
439 * Do not add TCP_NODELAY flag if the operating system
440 does not have it defined. Affected files are
441 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
443 * Fixed buffer overflow from Irssi SILC Client. Affected
444 file irssi/src/fe-common/core/themes.c.
446 * Fixed double free in client library in the file
447 lib/silcclient/client.c when disconnecting from server.
449 * Applied double free patch from cras to Irssi SILC client.
450 Affected files irssi/src/core/[modules/expandos].c
452 * Fixed the disconnection handling to Irssi SILC Client.
453 The application must call silc_client_close_connection
454 in ops->connect client operation in case of failure of
455 the connection. Affected file is
456 irssi/src/silc/core/client_ops.c.
458 * Do not set sock->protocol to NULL in the function
459 silc_client_close_connection after executing the protocol's
460 final callback since the sock might not be valid anymore.
461 Affected file lib/silcclient/client.c.
463 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
465 * Do not enable SILC_THREADS if the linking with libpthread
466 did not happen. Affected file configure.in.pre.
468 * Added notion to protocol specification that server must
469 verify the sent authentication payload with CMODE when
470 setting the channel founder key. Implemented it to the
471 server. Affected file silcd/command.c.
473 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
475 * Added _EXTRA_DIST SILC distribution variable to the
476 distributions file. It is used to conditionally add extra
477 files or directories to the specific distribution. Affected
478 files ./prepare, Makefile.am.pre and distributions.
480 Removed the `_' from the start of the distribution names.
483 * Added README.WIN32 for instructions to compile the Toolkit
486 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
488 * Fixed a double free in disconnection in the server. Affected
489 file is silcd/server.c.
491 * Fixed the lib/silcske/groups.c to work now also with GMP
492 MP library. The string conversion did not work when using
493 specific base and the base is indicated in the string as well.
495 * Created win32/ directory which now includes MSVC++ specific
496 stuff so that toolkit (DLLs) may be compiled with MSVC++.
497 It will appear only in the toolkit distribution
499 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
501 * Changed the key material distribution function in case when
502 the hash output is too short. The data is now concatenated
503 a bit differently than it used to. Made the change to the
504 SKE protocol specification.
506 * Added better GMP detection to configure.in.pre. A patch
509 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
511 * Fixed a minor bug in SKE that might cause some problem on
512 some platforms. Affected file lib/silcske/silcske.c.
514 * Added the cookie checking for initiator in the SKE. It checks
515 that the responder returns the sent cookie unmodified. The
516 affected file is lib/silcske/silcske.c. Added new SKE
517 error type INVALID_COOKIE that can be sent during the
518 negotiation. Fixed some memory leaks as well.
520 * Added the "invalid cookie" error message to Irssi SILC client's
523 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
525 * Added `task_max' field to the SilcClientParams to indicate
526 the maximum tasks the scheduler can handle. If set to zero,
527 default values are used. Affected file lib/silcclient/silcapi.h.
529 * Fixed memory leaks in silc_client_close_connection. Affected
530 file lib/silcclient/client.c.
532 * Added silc_client_del_client_entry to client library to free
533 all memory of given client entry. Affected file is
534 lib/silcclient/idlist.[ch].
536 * Added new functions silc_client_del_channel and
537 silc_client_del_server to delete channel and server entries.
538 Affected file lib/silcclient/[silcapi.h/idlist.c].
540 * Removed silc_client_del_client_by_id from silcapi.h.
542 * Fixed the INFO command to return the server's own info
543 correctly when querying by Server ID. Affected file is
546 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
548 * Removed the non-blocking settings in WIN32 code in the
549 silc_sock_[read/write] and added SleepEx instead. Affected
550 file lib/silcutil/win32/silcwin32sockconn.c. The availability
551 of input data is now checked with FIONREAD and ioctlsocket.
553 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
555 * Call silc_schedule_task_del_by_context in the
556 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
557 Affected file lib/silccore/silcprotocol.c.
559 * Call silc_protocol_cancel for active protocols in the
560 silc_server_close_connection if the funtion
561 silc_server_free_sock_user_data has not been called.
562 Affected file silcd/server.c.
564 * Generic tasks cannot be deleted using the del_by_fd
565 task deleting function since generic tasks does not match
566 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
568 * Added a notion to SILCOPER help file that the SILCOPER works
569 only on router server, not on normal server.
571 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
573 * Added for WIN32 support for the new scheduler as well.
574 Affected file lib/silcutil/win32/silcwin32schedule.c.
576 * Fixed the SHA1 implementation to work on various platforms.
578 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
580 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
581 API. It is part of the scheduler now. Everything else is
582 as previously but some functions has changed their names.
583 Checkout the lib/silcutil/silcschedule.h for the interface.
584 Updated all applications to use the new interface. Affected
585 files are lib/silcutil/silcschedule.[ch].
587 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
589 * Found a bug in the SKE implementation. The HASH value,
590 specified by the protocol, was not computed correctly. The
591 public key of the responder was not added to the computation
592 even though it is mandatory. Affected file lib/silcske/silcske.c.
593 This unfortunately causes incompatibilities with older
596 * Added WIN32 specific network init and uninit functions:
597 silc_net_win32_init and silc_net_win32_uninit to init and uninit
598 the Winsock2. Affected file lib/silcutil/silcnet.h and
599 lib/silcutil/win32/silcwin32net.c.
601 * Set the socket always to nonblocking mode on WIN32 after
602 reading data or writing data. Affected file is
603 lib/silcutil/win32/silcwin32sockconn.c.
605 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
607 * Fixed various compilation problems under WIN32. Affected
608 files lib/silcutil/win32/silcwin32thread.c and
609 lib/silcutil/win32/silcwin32schedule.c.
611 * Removed all _internal.h #includes from public header
612 files. Internal headers must never be included from
615 Removed also the lib/silcske/payload_internal.h file.
617 * All include files that may be needed (public and some others
618 included by the public headers) by application developers are
619 now copied to the ./includes directory. It does not copy any
620 internal headers. Affected file Makefile.defines.pre and all
621 Makefile.am's under lib/ and subdirs.
623 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
625 * Do not change the ~/.silc directory's permissions automatically.
626 Affected file irssi/src/silc/core/clientutil.c.
628 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
630 * Do not cancel the protocol in silc_server_close_connection
631 it might cause recursion. Now cancelled in the function
632 silc_server_free_sock_user_data. Affected file silcd/server.c.
634 * Fixed the silc_server_remove_clients_by_server to regenerate
635 the channel keys correctly finally. Added also new function
636 silc_server_remove_clients_channels to actually do it.
637 Affected file silcd/server.c.
639 * Fixed the silc_server_new_channel to not crash by giving
640 wrong router to the new channel. Affected file is
641 silcd/packet_receive.c.
643 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
645 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
646 which is given as argument to the silc_client_alloc now.
647 It can be used to configure the client and set various parameters
648 that affect the function of the client.
650 * The USERS command in server did not check whether the channel
651 is private or secret. Affected file silcd/command.c.
653 * Added new argument to the USERS command in protocol specification.
654 The USERS command now can take the channel name as argument
655 as well. Added support for this in client and server and
656 updated the protocol specs.
658 * Completed the GETKEY command in client. It can be now used
659 to fetch also servers public key not only some clients.
660 Affected files lib/silcclient/command[_reply].c.
662 * Added silc_client_get_server to return server entry by the
663 server name. Affected files lib/silcclient/silcapi.h and
666 * Redefined the IDENTIFY command in protocol specification to be
667 more generic. It now can be used to query information about
668 any entity in the SILC Network, including clients, servers and
669 channels. The query may be based either the entity's name
670 or the ID. Added support for this in both client and server.
672 Affected files silcd/command.c and lib/silcclient/command.c
675 * Optimized the WHOIS and WHOWAS commands in the server. Removed
676 the _from_client and _from_server functions. Affected file
679 * Added silc_client_get_channel_by_id_resolve to the file
680 lib/silcclient/silcapi.h to resolve channel information by
681 its ID. Added also silc_client_get_channel_by_id that
682 does not resolve it from the server.
684 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
686 * Added SilcServerEntry context into the client library
687 to represent one server. The INFO command now allocates
688 these to save the resolved server info. For now on the
689 client library will also keep information about servers,
690 connected and resolved with INFO.
692 The INFO command now allocates the SilcServerEntry context
693 and saves the server info there. The COMMAND_REPLY in
694 the INFO now returns the parameters to application in
695 same order as defined in the protocol specification.
697 The entries are cached in the client->server_cache.
699 * The INFO command is now issued after received the Client ID
700 from the server. Affected file lib/silcclient/client.c.
702 * The CMODE_CHANGE notify may now return also an SilcServerEntry
703 to the application as the mode changer might be server.
704 It is guaranteed that NULL is not returned anymore to the
705 application. Affected file lib/silcclient/client_notify.c.
707 The ID Type is now also passed to the application so that
708 it can check whether the returned entry is SilcClientEntry
711 Added new function silc_client_get_server_by_id to return
712 the server entry by ID. Affected files are the
713 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
715 * Do not create the channel in the Irssi SILC Client when issuing
716 the JOIN command but when received the sucessful JOIN command
717 reply. Otherwise the channel might get created even though we
718 could not join it. The Affected file is
719 irssi/src/silc/core/[silc-channels.c/client_ops.c].
721 * Fixed a channel joining bug in router. The router must also
722 check the channel modes, invite and ban lists etc. when serving
723 the JOIN command sent by normal server. Affected file is
724 silcd/command.c. The router now resolves the client's
725 information from the server who sent the JOIN command if it
726 does not know it, and processes the JOIN command only after
729 * Changed the SilcCommandCb to take new argument; void *context2.
730 Affected file lib/silccore/silccommand.h
732 The second argument in the command callbacks in the server now
733 includes the SilcServerCommandReplyContext if the command was
734 called as pending command callback from the command reply.
735 Otherwise it is NULL. When called as pending the status of the
736 command reply will be checked and if it was erronous the
737 error will be sent to the original sender of the command.
738 This way the client always receives the error messages even
739 though the server was actually the one who received the error
740 when it resent the command to router, for example. Affected
741 files silcd/command[_reply].[ch].
743 * Fixed sending WHOWAS command's error message to client if
744 the requested client could not be found. It was missing.
747 * Changed the CMODE and CUMODE commands reply arguments in the
748 protocol specification. The Channel ID is now sent in both
749 of the commands to identify the channel. Implemented this
750 new feature to the client and server. Affected files
751 lib/silcclient/command_reply.c and silcd/command.c.
753 * Made better checks for invite and ban lists in the JOIN
754 command in server. Affected file silcd/command.c.
756 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
758 * The server now performs the incoming host IP/DNS lookup
759 using the silc_socket_host_lookup and thus does not block
760 the server anymore. Affected file silcd/server.c.
762 * Completed the multi-thread support for SILC Scheduler in
763 the lib/silcutil/silcschedule.c.
765 * Fixed the configure.in.pre to detect the pthread correctly
768 * Fixed a deadlock in silc_task_queue_wakeup in the file
769 lib/silcutil/silctask.c.
771 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
773 * Added new function silc_schedule_wakeup that is used in
774 multi-threaded environment to wakeup the main thread's
775 schduler. It needs to be used when a thread adds a new task
776 or removes a task from task queues. After waking up, the
777 scheduler will detect the task queue changes. If threads
778 support is not compiled in this function has no effect.
779 Implemented the wakeup mechanism to both Unix and WIN32
780 systems. Affected files are lib/silcutil/silcschedule.[ch],
781 lib/silcutil/unix/silcunixschedule.c and the
782 lib/silcutil/win32/silcwin32schedule.c.
784 * Added new function silc_task_queue_wakeup to wakeup the
785 scheduler by the specified task queue. Affected file
786 lib/silcutil/silctask.[ch].
788 * The silc_socket_host_lookup_start now wakes up the scheduler
789 after adding the timeout task. Affected file is
790 lib/silcutil/silcsockconn.c.
792 * The silc_socket_host_lookup is synchronous now if the threads
793 support is not compiled in. However, the callback is still
794 called asyncronously through the scheduler, anyway. Affected
795 file lib/silcutil/silcsockconn.c.
797 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
799 * Added new function silc_socket_host_lookup to perform
800 asynchronous IP and FQDN lookups for the socket connection.
801 Affected files lib/silcutil/silcsockconn.[ch].
803 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
805 * Added SILC_MUTEX_DEFINE to define the mutex on environments
806 that may or may not compile the mutex support in.
808 Changed the silc_mutex_alloc interface. It allocates the
809 mutex now to the sent pointer and returns TRUE or FALSE.
811 Affected file lib/silcutil/silcmutex.h.
813 * Wrote the SILC Task Queue interface to support multi-threads.
814 Affected file lib/silcutil/silctask.[ch].
816 * Wrote the SILC Scheduler to support multi-threads. Affected
817 file lib/silcutil/silcschedule.c.
819 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
821 * Implemented the SILC Mutex API and SILC Thread API for WIN32
822 in lib/silcutil/win32/.
824 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
826 * Defined SILC Mutex API and SILC Thread API and implemented
827 them for Unix. Affected files are
828 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
829 lib/silcutil/unix/silcunixmutex.c and
830 lib/silcutil/unix/silcunixthread.c.
832 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
834 * Fixed the silc_server_remove_clients_by_server's channel
835 key re-generation. The hash table handling was incorrect
836 and would not work with many channels. Affected file is
839 * Fixed some memory leaks around the server code.
841 * Rewrote the silc_server_get_users_on_channel to support IPv6
842 based Client ID's. Affected file silcd/server.c.
844 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
845 specification. However, a separate document must be written
846 to define the detailed signing procedure and the payload
847 associated with the flag. Defined the flag to the
848 lib/silccore/silcchannel.h as well.
850 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
852 * Changed the dynamic tables to static size tables in the
853 lib/silccrypt/silchmac.c.
855 * Removed GCC dependencies from the code. A patch by cras.
857 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
859 * Do not show the error "Error receiving packet bla bla"
860 in server if it really was not an error (-2 means that reading
861 is pending). Affected file silcd/server.c.
863 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
865 * Fixed a possible crash in silc_server_remove_clients_by_server
866 in silcd/server.c. Fixed there also some memory leaks.
868 * Fixed the silc_idlist_replace_client_id. It could replace
869 wrong key in the hash table. Affected file silcd/idlist.c.
871 * Do not check whether there are global users on the channel
872 if the channel->global_users is FALSE. Affected functions
873 silc_server_remove_from_one_channel and
874 silc_server_remove_from_channels in silcd/server.c. Also,
875 do not check if the removed client is local as we can be
876 sure that global client was not removed from the channel
877 and checking for global users is not needed.
879 * The silc_server_remove_clients_by_server now re-generates
880 the channel keys correctly for those channels that had
881 clients removed from them. Affected file silcd/server.c.
883 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
885 * Found the reason of random crashes in the server. We weren't
886 ignoring the SIGPIPE signal (which can be sent in write())
887 and it crashed the server. Affected file silcd/silcd.c.
889 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
891 * Assure that sock->user_data is not NULL in the function
892 silc_server_packet_send in silcd/packet_send.c.
894 * Disconnect the remote connection if it could not be added
895 to any ID lists in the server. The affected file is
898 * Check in silc_server_packet_send[_real/dest] that the
899 socket is not disconnecting and ignore the data if it is.
900 Affected file silcd/packet_send.c.
902 * Define inline to __inline on native WIN32 compilation.
903 Affected file includes/silcwin32.h.
905 * Added some explicit type casts for inline code since MSVC
906 require them. Affected files lib/silcutil/silcbuffer.h,
907 lib/trq/silcdlist.h and lib/trq/silclist.h.
909 * Print warning in log files from now on if the packet
910 decryption fails. Affected file silcd/server.c.
912 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
914 * Changed the `say' client operation's interface to accept
915 new `type' argument to indicate the type of the message sent
916 by the library. The application may filter the library's
917 messages according the type. The affected file is the
918 lib/silcclient/silcapi.h.
920 * Added two new functions to lib/silcclient/silcapi.h:
921 silc_client_del_client and silc_client_del_client_by_id.
922 Affected file lib/silcclient/idlist.c.
924 * Moved the clientincludes.h from includes/ to silc/ and
925 serverincludes.h from includes/ to silcd/.
927 * The modes for the CMODE and CUMODE are now passed as
928 uint32 for application with COMMAND_REPLY. The affected
929 file is lib/silcclient/command_reply.c.
931 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
933 * /WHOIS without arguments shows client's own information.
934 Affected file lib/silcclient/command.c.
936 * Changed PING to not accept any arguments. The specs
937 says that client can ping only the connected server so
938 requiring an argument is not needed. Affected file is
939 lib/silcclient/command.c.
941 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
943 * Fixed a fatal bug in private message sending and reception
944 encryption and decryption when using private message keys.
945 The implementation was incorrect and did not follow the
946 specification. It causd that some of the message were
947 lost since it did not use the sending and receiving keys
948 as the protocol suggests. This has been fixed and will cause
949 incompatibilities with older clients when sending private
950 message encrypted with private message keys. Affected files
951 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
952 and various other in Irssi SILC Client.
954 Added `responder' boolean argument to the functions
955 silc_client_add_private_message_key[_ske] to indicate when
956 the key is added as responder or initiator of the key
959 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
961 * Removed the silc_ske_check_version function and created
962 a SilcSKECheckVersion callback. Added also a function
963 silc_ske_set_callbacks that is now used to set all SKE
964 callbacks. The callback functions are not given to
965 the SKE functions anymore, but this function is used to
968 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
970 * Added `silc_version' argument to the silc_client_alloc
971 to define the version of the application for the library.
972 The library will use the version string to compare it
973 against the remote host's (usually a server) version
974 string. Affected file lib/silcclient/silcapi.h
976 * Added the KE protocol context to Key Agreement context
977 in client library so that we can abort the SKE if it
978 is in process when we get timeout. Affected file is
979 lib/silcclient/client_keyagr.c.
981 * Do not resolve the client ID forever if it returns in the
982 first time that such client does not exist. This was done
983 for example with private message. Affected file is
984 lib/silcclient/client_prvmsg.c.
986 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
988 * Do not add regex.h for WIN32. The affected file
989 includes/silcincludes.h.
991 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
992 not work yet 100%. It generates the DLL's automatically
993 when compiling with --with-win32 under cygwin.
995 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
997 * lib/contrib/regex.c is not compiled on WIN32.
999 * Added silc_net_get_socket_opt function to the
1000 lib/silcutil/silcnet.h.
1002 * Added includes/silcwin32.h for WIN32 specific includes
1005 * Do not use ptime structure or any of the posix process
1006 functions on WIN32 in lib/silccrypt/silrng.c.
1008 * Added silc_gettimeofday to provide generic function
1009 for struct timeval on all platforms. Added the function
1010 to lib/silcutil/silcutil.h.
1012 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1014 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1015 library as they clearly belong there. As a plus side we
1016 can make the actual socket connection routines platform
1019 Added also new generic function silc_socket_read and
1020 silc_socket_write (that used to be silc_packet_[read/write].
1021 The implementation of these are platform specific.
1023 * Added WIN32 specific routines of silc_socket_[read/write]
1024 to lib/silcutil/win32/silcwin32sockconn.c.
1026 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1028 * Added preliminary support for native WIN32 compilation under
1029 cygwin (using the -mno-cygwin option for GCC) to the
1030 ./configure.in.pre. The --with-win32 now prepares the
1031 compilation for native WIN32.
1033 * Rewrote the SILC Scheduler interface in the file
1034 lib/silcutil/silcschedule.h. The scheduler is now context
1035 based and does not have anymore any global static scheduler.
1036 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1037 and created lib/silcutil/win32 directory for WIN32 based
1040 * Added Unix specific network routines to the
1041 lib/silcutil/unix/silcunixnet.c and the old
1042 lib/silcutil/silcnet.c includes now only generic routines.
1044 Added WIN32 specific network routines to the
1045 lib/silcutil/win32/silcwin32net.c.
1047 * Added Unix specific utility functions from the
1048 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1050 * Added WIN32 SILC Scheduler to the file
1051 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1054 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1056 * Do not handle JOIN notify in the server if the target client
1057 is not registered (idata->registered == FALSE). The affected
1058 file is silcd/packet_receive.c.
1060 * Update the nickrec->founder in event_cumode in the Irssi SILC
1061 client. Affected file irssi/src/silc/core/silc-channels.c.
1063 * Fixed the CUMODE_CHANGE notify handling in the server when
1064 server and router are announcing their clients on channels.
1065 Now the mode changes are saved and notified correctly. The
1066 affected file is /silcd/packet_receive.c.
1068 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1069 They really did not replace the cache entry in the ID Cache.
1070 Now they do that. Affected file silcd/idlist.c.
1072 * Fixed the KICK notify handling in the Irssi SILC client to
1073 update the channel records so that the kicked client does not
1074 appear to be on the channel. The affected file is
1075 irssi/src/silc/core/silc-channels.c.
1077 * Always update the conn->current_channel when executing command
1078 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1080 * Fixed the KILL notify handling in Irssi SILC client to remove
1081 the killed client on all channels.
1083 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1085 * Fixed the silc_parse_command_line to remove extra spaces
1086 from the start and end of the arguments. Affected file is
1087 lib/silcutil/silcutil.c.
1089 * Cancel and free any active protocol in the function
1090 silc_server_close_connection. Affected file silcd/server.c.
1092 * Cancel and free any active protocol in the function
1093 silc_client_close_connction. Affected file is
1094 lib/silcclient/client.c.
1096 * Do not execute the KILL command for clients that are in
1097 history (ie. they are not in the network). Affected file is
1100 * Fixed KILL notify handling, client does not crash anymore.
1101 Affected file irssi/src/silc/core/silc-channels.c.
1103 * Reduced the default packet buffer size from 2048 to 1024 in
1104 lib/silccore/silcpacket.c.
1106 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1107 counter to the SKE context that is incresed when the SKE library
1108 performs async operation outside the library. If the outside
1109 process frees the SKE context and FREED status will be set
1110 and the library will detect after the sync operation that the
1111 libary is freed. The affected files are
1112 lib/silcske/silcske[_status].[ch].
1114 * Resolve the client entry information in the function
1115 silc_client_channel_message to assure that NULL pointer is not
1116 passed as client entry to the application. */
1118 * Fixed the task timeout calculation to assure that there is
1119 never negative timeouts. The affected file is
1120 lib/silcutil/silcschedule.c.
1122 * Fixed the channel user mode notification sending in server.
1123 It was sent point-to-point to the router (or to server by router)
1124 but it needs to be destined to a channel. The routines now
1125 supports sending the channel user mode notifys to the channels
1126 when announcing clients and channels. Affected files are
1127 silcd/server.c and silcd/packet_receive.c.
1129 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1130 It did not actually replace the old channel entry in the cache.
1131 Affected file lib/silcclient/client_notify.c.
1133 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1135 * Fixed a possible crash in silc_packet_send_prepare. It now
1136 assures always that there is enough space in the buffer and
1137 at the tail area of the buffer (for MAC).
1139 Fixed the inbound buffer reallocation in silc_packet_read.
1140 It was old code and did not handle the reallocation correctly.
1143 The affected file is lib/silccore/silcpacket.c.
1145 * Fixed buffer overflow in silc_parse_nickname in the file
1146 lib/silcutil/silcutil.c.
1148 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1150 * make install generates new server keys only if there is not
1153 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1155 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1156 Added check that if the NOREPLY is set then we will not send
1157 the away message. This avoids infinite loop of away messages
1158 if both clients are away. The affected file is
1159 lib/silcclient/client_prvmsg.c.
1161 * Fixed client crash if /NICK was given without arguments.
1162 Affected file lib/silcclient/command.c.
1164 * Server does not send the invite list in INVITE command back
1165 to the client if the list was not altered. Added this notion
1166 to the protocol spec as well. Affected file silcd/command.c.
1168 Fixed possible crash in INVITE command by checking the
1169 value of silc_server_get_client_route command.
1171 * Fixed the INVITE notify type handling. The arguments are now
1172 taken in correct order and client does not crash. The affected
1173 file is irssi/src/silc/core/silc-channels.c.
1175 Removed the "Inviting xxx to channel" message from the
1176 client library away and let the application handle it.
1177 Affected file lib/silcclient/command.c. Added that message
1178 to Irssi SILC client's message formats.
1180 * Fixed CMODE command crash in client. It now checks the
1181 amount of arguments correctly and does not crash. The affected
1182 file is lib/silcclient/command.c.
1184 * Do not create new channel automatically in silc_channels_join
1185 but check whether the channel by that name already exists.
1186 Affected file irssi/silc/core/silc-channels.c.
1188 * Do not send the SERVER_SIGNOFF to router if the disconnected
1189 entity was the router. Affected file silcd/server.c.
1191 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1192 SILC client as it was missing from there.
1194 Added the handling of the KICK notify to the Irssi SILC client
1195 as it was missing. Added "you have been kicked" message to
1196 Irssi SILC client's message modules formats.
1198 Added the handing of the KILL notify to the Irssi SILC client
1199 as it was missing. Added the kill message module formats
1202 The affected file is irssi/src/silc/core/silc-channels.c.
1204 * The router did not save the channel mode the server announced.
1205 Affected file silcd/packet_receive.c.
1207 * Fixed a possible crash in INFO command in server. If the
1208 server did not provide the server info it crashed. Affected
1209 file silcd/command.c.
1211 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Fixed the GETKEY command in the server to check also the
1214 global list. Otherwise the GETKEY would not work correctly
1215 in normal SILC server. Affected file silcd/command.c.
1217 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1219 * Fixed GETKEY crash, it crashed if the command did not succseed.
1221 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1223 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1224 is now real and not just an macro interface to GMP.
1226 Removed the entire GMP from the source tree and imported new
1227 NSS MPI library instead. Reason for removing GMP is that it is
1228 extremely large and compiles extremely slow. The NSS MPI
1229 is only a few files and compiles in less than 10 seconds.
1230 The speed is also about the same as GMP. The MPI is imported
1231 to lib/silcmath/mpi.
1233 If the system has GMP installed we will still use the GMP.
1234 If it is not then the NSS MPI will be compiled.
1236 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1238 * Merged a long nickname (127 characters long) crash bugfix from
1239 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1241 * Merged a freed memory reference bugfix from Irssi CVS tree.
1242 Affected file irssi/src/core/commands.c.
1244 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1246 * Added the server's public key sving and verification to the
1247 server when performing the SKE. This was missing and the
1248 remote server's (or router's) public key was accepted without
1249 checking whether we have it previously or trust it at all.
1250 Affected file silcd/protocol.c.
1252 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1254 * Check in the silc_server_timeout_remote if protocol is active
1255 and make sure that the protocol's final callback is called so
1256 that all memory if freed. Affected file silcd/server.c.
1258 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1260 * silc_server_whois_send_reply crashed the server if the nickname
1261 was 127 characters long. Affected file silcd/command.c.
1263 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1265 * Added sanity check to the silc_server_new_client. If the hostname
1266 is provided inside username then check that the provided hostname
1267 really is the same as the resolved one. If the hostname was not
1268 resolved then check it from the public key. Affected file is
1269 silcd/packet_receive.c.
1271 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1272 if the server disconnected us and the connection is not valid
1273 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1275 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1276 the library to the lib/silcutil/silcutil.[ch].
1278 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1280 * Close log file after open. Affected file
1281 lib/silcutil/silclog.c.
1283 * Check whether sock == NULL in silc_client_send_packet and return
1284 if it is. Affected file lib/silcclient/silcclient.c.
1286 * Check rec->entry == NULL in the Irssi SILC Client before
1287 sending the channel message. Affecte file is
1288 irssi/src/silc/core/silc-servers.c.
1290 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1292 * Merged a splitted window bugfix from Irssi CVS tree. The
1293 affected file is irssi/src/fe-text/textbuffer-view.c.
1295 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1296 It did not print nickname.
1298 * Improved the distributions system a bit.
1300 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1302 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1303 irssi/src/fe-text/gui-window.c.
1305 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1306 to in-active server. The affected file is
1307 irssi/src/silc/core/client_ops.c.
1309 * Resolve the client in USERS command reply if the entry does
1310 not have username resolved. The affected file is
1311 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1312 command to WHOIS command to really resolve stuff. The USERS
1313 is not used any more in any critical section so WHOIS can
1314 be used even though it might be slower than IDENTIFY.
1316 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1319 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1321 * Changed the protocol API a bit more consistent in the
1322 lib/silccore/silcprotocol.[ch].
1324 * Changed the following headers to ROBODoc format:
1326 lib/silccore/silcpayload.h
1327 lib/silccore/silcprotocol.h
1328 lib/silccore/silcsockconn.h
1330 All core library headers are now formatted.
1332 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1334 * Fixed a bug in Irssi SILC client; do not show that you are
1335 server/router operator if you really are not. Affected file is
1336 irssi/src/silc/core/client_ops.c.
1338 * Renamed silc_command_free_payload to silc_command_payload_free.
1339 Affected file lib/silccore/silccommand.h
1341 * Added silcmath.h to include the prototoypes of various routines
1342 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1345 * Changed the following headers to ROBODoc format:
1347 lib/silccore/silcchannel.h
1348 lib/silccore/silccommand.h
1349 lib/silccore/silcid.h
1350 lib/silccore/silcidcache.h
1351 lib/silccore/silcmode.h
1352 lib/silccore/silcnotify.h
1353 lib/silccore/silcpacket.h
1354 lib/silcmath/silcmath.h
1356 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1358 * Added checking to the server code not to start the server if
1359 ciphers and stuff are not configured properly. Affected files
1360 silcd/serverconfig.[h] and silcd/server.c.
1362 * Changed the layout of the header files of the public interfaces
1363 in the SILC libraries. The new layout supports ROBODoc
1364 documentation tool (and some others) so that it is easy to create
1365 a library reference manual. All the other headers and source
1366 code must still follow the CodingStyle document. Also source
1367 code must not include these ROBODoc stuffs, only the headers.
1368 Furthermore, all public interface headers must now be named
1369 by using `silc' prefix, example: silcapi.h, silccipher.h.
1370 Some files were renamed due to this. All the other headers
1371 must not be used as public interfaces. I will update the
1372 CodingStyle document later. Changed following headers, so far:
1374 lib/silcclient/silcapi.h
1375 lib/silccore/silcauth.h
1376 lib/silccore/silcprivate.h
1377 lib/silccrypt/silcdh.h
1379 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1383 * Removed silc_client_packet_send_flush from the client library
1384 as it is not needed. Affected file lib/silcclient/client.[ch].
1386 * Added printing of message of unresolved authentication method
1387 to the Irssi SILC client. Added it to the module formats.
1388 Removed the same message from the client library.
1390 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1392 * Added new distribution feature, DISTLABEL. Every distribution
1393 can define own preprocessor label that can be used in the
1394 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1395 file distributions, acconfig.h.pre and prepare.
1397 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1399 * Added Makefile.defines_int to include the actual definitions
1400 for Makefile.defines.in. Tested the new distribution system,
1401 created distributions and tested installation.
1403 * Added AWAY message printing to the Irssi SILC client. Added
1404 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1406 * Added SCONNECT command to call the SILC's CONNECT command.
1407 Cannot use CONNECT directly since Irssi uses that internally.
1408 Affected file irssi/src/silc/core/silc-servers.c.
1410 Added ACTION local command. It is same as ME command but takes
1411 the channel as mandatory argument.
1413 Rewrote some of the Irssi's help files to suite for SILC
1416 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1418 * Added Makefile.defines[.in] that should for now on be included
1419 in all Makefile.am file in the source tree. That file includes
1420 all common compilation definitions for SILC source tree.
1422 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1424 * Minor changes to the ./prepare script to change the package
1425 name according the distribution name to the configure.in.
1427 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1429 * Created new distribution system. Added file `distributions'
1430 that defines all the distributions that can be created out of
1431 the SILC source tree. The ./prepare script now reads that
1432 file to determine how to prepare the distributions. The
1433 first argument to the ./prepare is the name of the distribution
1434 and second is the version of the distribution. If given
1435 without arguments it creates the default (toolkit) distribution
1436 with the default version (defined in ./prepare).
1438 All Makefile.am files that are subject to the distributions
1439 are now named as Makefile.am.pre. These are ./Makefile.am
1440 and lib/Makefile.am. Others may be changed later.
1442 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1444 * Added invite list, ban list, some key management and connection
1445 error message printing to module formats in the Irssi SILC client.
1447 * Added new silc_client_set_away_message to set the away message
1448 that is back to the person who sent private message. The
1449 affected file lib/silcclient/silcapi.h and the
1450 lib/silcclient/client_prvmsg.c.
1452 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1454 * Fixed the private message sending in the Irssi SILC client,
1455 added local command KEY to the Irssi SILC client.
1457 Added key management and key agreement message formats to the
1458 irssi/src/fe-common/silc/module-formats.[ch].
1460 Added USERS (alias WHO) printing, server/router operator
1461 indication and LIST command printing to the module formats.
1463 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1465 * Fixed channel joining notify handling, cumode notify handling
1466 from Irssi SILC client.
1468 * Added SILC specific module-formats to the Irssi SILC client so
1469 that SILC specific message hilighting, colors etc is possible.
1470 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1472 Added channel mode, channel user mode, actions, notices,
1473 whois and whowas printing to the the module-formats.c.
1475 * Fixed a bug in channel deletion in the server. The channel
1476 is not left to the cache even if the channel founder auth mode
1477 is set when there are no users anymore on the channel. Affected
1478 file silcd/server.c.
1480 * The silc_net_localhost now resolves the entire hostname including
1481 the domain name. Affected file lib/silcutil/silcnet.c.
1483 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1485 * Changed the ask_passphrase client operation to be ascynchronous.
1486 It has now a completion callback and a context that the
1487 application must call after it has got the passphrase from
1488 the user. Affected files lib/silcclient/silcapi.h,
1489 lib/silcclient/protocol.c, lib/silcclient/command.c and
1492 Added SilcAskPassphrase callback that the application calls
1493 to deliver the passphrase to the library.
1495 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1496 The public key verification and especially a certificate
1497 verification is asynchronous procedure.
1499 Added new SILC_SKE_STATUS_PENDING status to indicate the
1500 request is pending and a callback will be called to finalize
1503 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1504 indicate that remote end did not send its public key (or
1505 certificate), even though we require it. Added check for this
1506 condition in the SKE. This was a security bug, now fixed.
1508 Defined new SilcSKEVerifyCbCompletion callback that is called
1509 when the verification process is completed.
1511 The affected files lib/silcske/silcske_status.h and
1512 lib/silcske/silcske.[ch].
1514 * Changed the verify_public_key client operation to be async
1515 as well. Defined SilcVerifyPublicKey callback that is used to
1516 indicate the success of the public key verification process.
1518 Changed the server and client to use the new async client
1521 * Changed the Irssi SILC client's internal scheduler to be called
1522 twice as many times as it used to be. As a result the client
1523 should be a bit faster now. Affected file is
1524 irssi/src/silc/core/silc-core.c.
1526 * Added support to Irssi SILC client of asynchronous public key
1527 verification and passphrase inquiry. Affected file is
1528 irssi/src/silc/core/silc-core.c.
1530 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1532 * Do not say "You have left channel %s" in client library.
1533 Moved it to the application. Affected files are
1534 lib/silcclient/command.c and silc/client_ops.c.
1536 * Fixed silc_client_get_clients. Command context was not
1537 duplicated and was freed memory in the callback. Affected
1538 file lib/silcclient/idlist.c.
1540 * Do not say "you are now talking..." on JOIN command in the
1541 client library. The appliation must handle it.
1543 * Do not say ".. changed topic to" in command reply in the
1544 client libary. The application must handle it.
1546 * Fixed TOPIC command sending in the client library.
1548 * Fixed a memory leak in silc_client_command_free in the file
1549 lib/silcclient/command.c.
1551 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1553 * Imported a modified version of Irssi client to the source tree.
1554 The Irssi will be used to create a new client called
1555 Irssi SILC. Imported to irssi/.
1557 Added silc_core_init_finish function to the Irssi. Affected
1558 file irssi/configure.in.
1560 A lot changes in the Makefile.ams around the irssi tree.
1562 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1564 * Do not rehash if the new size is same as the old size of the
1565 hash table, in the silc_hash_table_rehash*. The affected file
1566 lib/silcutil/silchashtable.c.
1568 * Replaced hash_table_del_by_context calls from the server
1569 (when channel->user_list and client->channels) to the
1570 hash_table_del as it is sufficient and faster.
1572 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1574 * Added silc_hash_table_list, silc_hash_table_get and the
1575 SilcHashTableList structure to provide an alternative way to
1576 traverse the hash table. The affected files are
1577 lib/silcutil/silchashtable.[ch].
1579 * Changed the server's idlist routines to use the hash table
1580 routines to optimize the code.
1582 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1584 * Replaced the client entry's `channel' list and channel entry's
1585 `user_list' list to hash tables for optimized lookup. Changed
1586 the code to use the hash table interface around the code.
1587 Affected file lib/silcd/idlist.[ch].
1589 * Added `auto_rehash' boolean argument to the function
1590 silc_hash_table_alloc to indicate whether the hash table should
1591 auto-rehash when it thinks is appropriate time. It will
1592 increase the hash table size if the there is twice as much
1593 entries in the table than the size of the table, and will
1594 decrease the size if there are twice as less entries than
1595 the size of the table.
1597 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1599 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1601 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1603 * silc_idcache_purge_by_context deletes the entry now by context
1604 as it is supposed to do. Affected file lib/silccore/idcache.c.
1606 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1607 client is not anymore valid (WHOWAS givens the info) and not
1608 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1610 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1612 * Removed the `data' and `data_len' arguments from the ID Cache
1613 interfaces and added `name' argument. ID Cache does not handle
1614 anymore the binary data only a names associated with given ID.
1616 * When hashing a Client ID with silc_hash_id the entire ID is
1617 not hashed anymore, instead only the hash of the Client ID is
1618 hashed. This way we can access the Client ID from the cache
1619 with Client ID but with the hash of the ID (which is a hash of
1620 the nickname) as well without any difference in performance.
1622 Added also silc_idcache_find_by_id_one_ext to do one on one
1623 searching when we have the actual ID. Added also function
1624 silc_hash_client_id_compare. The affected files are
1625 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1627 * When hashing the name associated with a ID it is always done
1628 in lowercase. This way we can access the cache without worrying
1629 about case-sensitivity, even though, for example nicknames are
1632 * Fixed a bug in server with channel message sending. It put
1633 wrong ID type as destination ID. The affected file
1634 silcd/packet_send.c.
1636 * silc_idcache_del_by_context now deletes from all hash tables
1637 by context. Affected file lib/silccore/idcache.c.
1639 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1641 * Changed the client library to use the new ID Cache interface.
1642 Changes around the source tree.
1644 * Added silc_hash_table_rehash_ext to rehash with specific
1645 hash function. Affected file lib/silcutil/silchashtable.[ch].
1647 * Added silc_hash_string_compare to compare two strings in the
1648 hash table. Affected file lib/silcutil/silcutil.[ch].
1650 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1652 * Added new function silc_idcache_del_by_context into the
1653 lib/silccore/idcache.[ch].
1655 * Changed the server's ID list routines to use the new ID Cache
1656 interface. Changes around the source tree.
1658 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1660 * Added silc_hash_table_del[_by_context]_ext functions in to the
1661 lib/silcutil/silchashtable.[ch].
1663 Removed silc_hash_table_find_all* routines and added new
1664 silc_hash_table_find_foreach to replace them.
1666 Added silc_hash_table_replace_ext function as extended
1667 replacing function. Separated the simple hash table interface
1668 from the extended hash table interface in the file
1669 lib/silcutil/silchashtable.h.
1671 * Fixed minor bugs and changed it to use some of the new
1672 hash table functions in lib/silccore/idcache.c
1674 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1676 * Added new function silc_hash_table_find_all to return all keys
1677 in the hash table by the specified key. As the hash table is
1678 collision resistant it also makes it possible to have several
1679 duplicate keys in the hash table. This function may be used to
1680 find all of the keys from the hash.
1682 Added user_context arguments to the SilcHashFunction,
1683 SilcHashCompare and SilcHashDestructor to deliver user specified
1686 Added new fuctions silc_hash_table_find[_all]_ext to do
1687 extended lookup with specified hash and compare functions and
1688 specified user contexts.
1690 Added new function silc_hash_table_add_ext to add the key
1691 with specified hash function and user context.
1693 Added new function silc_hash_table_foreach to traverse all
1694 entrys in the hash table. Added SilcHashForeach callback
1697 Added new function silc_hash_table_del_by_context to delete
1698 the entry only if the context associated with the key matches.
1700 Affected files are lib/silcutil/silchashtable.[ch].
1702 * Removed silc_hash_[server/client/channel]_id and added just
1703 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1704 silc_hash_id_compare to compare two ID's using as the hash table
1705 comparison function. Added also silc_hash_data to hash
1706 binary data and silc_hash_data_compare to compare it.
1708 * Removed silc_idlist_find_client_by_hash as it is not needed
1709 anymore. Affected file silcd/idlist.[ch].
1711 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1712 to use internally the SilcHashTable. The new ID Cache is a lot
1713 faster than the old one. Some of the ID Cache interface was also
1714 rewritten and obsolete and stupid functions were removed.
1716 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1718 * Added entry_count field to the SilcHashTable to keep the number
1719 of the entries in the table. Implemented the function
1720 silc_hash_table_rehash. Added new function
1721 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1723 Fixed a minor bug in silc_hash_table_free.
1725 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1726 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1727 into the lib/silcutil/silcutil.[ch].
1729 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1731 * Implemented a collision resistant hash table into the
1732 lib/silcutil/silchashtable[ch]. See the header and the source
1733 for the SilcHashTable API.
1735 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1737 * Merged dotconf version 1.0.2 into lib/dotconf.
1739 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1741 * Do not compile anything in lib/silcsim/* if the SIM support
1742 is not enabled. The tree should now compile without problems
1745 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1747 * Compiled the SILC under cygwin. Compiled and tested briefly
1748 without problems. More tests needed. The SIMs didn't compile
1751 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1753 * Fixed possible crash in silc_get_username in the
1754 lib/silcutil/silcutil.c.
1756 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1758 * Fixed a va_arg in silc/client_ops.c.
1760 * Oops, RC5 routines were named AES and caused some problems
1761 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1763 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1765 * Added new SilcIDIP structure into the lib/silccore/id.h and
1766 replaced the old `ip' fields from all SILC ID's to that type.
1767 This is a step towards IPv6 support.
1769 The silc_id_get_len takes now the ID as an extra argument.
1770 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1771 both IPv4 and IPv6 based ID's.
1773 The affected files are lib/silccore/id.[ch] and other files
1774 around the tree using these routines.
1776 * Removed the ID length arguments in server from various
1777 silc_server_send_notify_* routines -> they are not needed
1780 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1782 * Fixed memory leak in silc_encode_pem_file in the file
1783 lib/silcutil/silcutil.c.
1785 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1787 * Check minor version as well in the SKE. Affected files are
1788 silcd/protocol.c and lib/silcclient/protocol.c.
1790 * Added --identifier option to the server so that an identifier
1791 can be when creating the public key for the server. Affected
1792 file is silcd/silcd.c.
1794 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1795 lib/silccrypt/silcpkcs.c.
1797 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1799 * Register default ciphers and stuff when using -C option with
1800 the server. Affected file sildc/silcd.c.
1802 * Put back the servers public key filename format, it is better
1803 than the new one. For now, the client keys are saved with the
1804 new filename format. The affected file silc/client_ops.c.
1806 * Implemented the Cipher API for the rest of the ciphers that
1807 did not implement it or implemented it the wrong way.
1809 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1811 * Register default ciphers and stuff when using the -S option
1812 in the client. Affected file silc/silc.c. Same also when
1813 creating new key pair with -C option.
1815 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1817 * Fixed the silc_verify_public_key client operation function to
1818 save the public keys differently. The fingerprint is now
1819 used as filename and not the hostname. This way also the
1820 client keys are saved uniquely and not with hostnames. The
1821 affected file is silc/client_ops.c.
1823 * Trimmed the silc_hash_fingerprint function to remove extra
1824 whitespaces from the end of the fingerprint. The affected
1825 file is lib/silccrypt/silchash.c.
1829 * Added silc_cipher_register_default function to register all
1830 default ciphers. It can be used when configuration files
1831 does not exist and the application does not want any specific
1832 ciphers in any specific order.
1834 The SilcDList is now used as silc_cipher_list dynamically
1835 allocated cipher list. Removed the static list all together
1836 and now all ciphers must be allocated to the dynamic list.
1837 The silc_cipher_alloc routine was changed to check only the
1840 All silc_cipher_* routines that used to return int returns
1843 The affected files lib/silccrypt/silccrypt.[ch].
1845 * The same thing was done to silc_hash_* as for silc_cipher_*
1846 routines. Affected files lib/silccrypt/silchash.[ch].
1848 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1849 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1850 Added also silc_pkcs_[un]register[_default] functions.
1851 Removed the data_context from the PKCS API.
1853 * Added silc_hmac_register_default function to register default
1854 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1855 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1856 to unregister all hmacs at once.
1858 * Register the default ciphers, hash functions, PKCSs and HMACs
1859 if client's configuration file does not exist. The affected
1862 * The client did not load the hash functions from the SIM
1863 modules at all. Added support for this. Affected file is
1864 silc/clientconfig.c.
1866 * When decoding public key with silc_pkcs_public_key_decode, check
1867 the supported algorithm only if PKCS are registered. Affected
1868 file lib/silccrypt/silcpkcs.c. The same was done with the
1869 silc_pkcs_private_key_decode.
1871 * Fixed the SILC List routines to keep the list always in order.
1872 It used to change the list's order when traversing the list but
1873 not it preserves the order. Affected file lib/trq/silclist.h.
1875 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1877 * Added the client library to use the SilcSocketConnection's
1878 reference counter (by silc_socket_dup) to prevent the bug that
1879 the socket object may be freed underneath async operation.
1881 * The name resolv library checking fixes in the configure.in.pre.
1884 * Created new version of the protocol drafts for future
1885 development. The -03 drafts are the ones that will be changed
1886 in the trunk now and the -02 will remain as they are.
1888 * Send list of CUMODE notifys to the router when announcing
1889 the channel users to the router. Affected file silcd/server.c.
1890 If the router receiving channel founder CUMODE for a channel
1891 that already has channel founder it will send CUMODE notify
1892 to the sender to remove the channel founder rights from the
1893 announced client. Affected file silcd/packet_receive.c.
1895 * The CUMODE notify may now use Server ID as well as the entity
1896 who changes the mode. Updated protocool specs.
1898 * Updated INSTALL and README files.
1900 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1902 * New web pages in the http://silc.pspt.fi. The pages was
1907 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1909 * Implemented the [DenyConnectin] config section in the server.
1910 Added silc_server_config_denied_conn to check whether incoming
1911 connection is denied. Affected file silcd/serverconfig.[ch].
1913 * Do not check the ports when checking the incoming configuration
1914 data if the port is 0, meaning any. Affected file is
1915 silcd/serverconfig.c.
1917 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1919 * Fixed buffer overflow in silc_string_compare in the file
1920 lib/silcutil/silcutil.c.
1922 * Fixed double free in silc_server_command_leave in the file
1925 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1927 * Fixed the version checking in the server. Affected file is
1930 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1932 * Fixed the configuration data fetching when accepting new
1933 connections in the server. Affected file silcd/server.c.
1935 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1937 * Added `sender_entry' argument to the function
1938 silc_server_packet_relay_to_channel so that we can check
1939 whether some destination actually belongs to the same route
1940 the sender belongs (ie, we must not resend the packet to the
1941 sender). Affected file silcd/packet_send.[ch].
1943 * Added `servername' field to the SilcClientEntry in the server
1944 to hold the name of the server where client is from. Affected
1945 file is silcd/idlist.h.
1947 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1949 * Moved the channel message encrypting in the router betwen
1950 router connections from silc_server_channel_message to the
1951 silc_server_packet_relay_to_channel since we want to check
1952 whether we have anybody channel before encrypting anything.
1953 Affected files silcd/packet_[receive/send].c.
1955 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1957 * Fixed the [AdminConnection] server config section to support
1958 multiple entries. Affected file silcd/serverconfig.c.
1960 * Added support into the server to check the validity of the
1961 incoming connection before executing any KE or authentication
1964 * The connection configuration is now saved to the KE and
1965 connection auth protocol contexts and not fetched anymore in
1966 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1968 * The local hosts listenning address and port is also resolved
1969 now when starting the server. We want to have the socket object
1970 to include the real address and port for the listener. Added
1971 new function silc_net_check_local_by_sock into the files
1972 lib/silcutil/silcnet.[ch].
1974 * Fixed a broadcast bug in server -> do not broadcast if we
1977 * Fixed a routing bug. Do not route broadcast packets ever.
1978 Broadcast packets must be processed always and not routed since
1979 they may be destined to some other host than yourself and thus
1980 would get routed without no good reason. Affected file is
1983 * Added function silc_server_config_is_primary_route to check
1984 whether primary router connection has been configured (a router
1985 configuration that we are initiating). If there is not, we
1986 will assume that there is only two routers in the SILC network
1987 and we will use the incoming router connection as our primary
1988 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1990 * Changed the order of the broadcasting. Broadcast _after_ the
1991 packet has been processed not before. Affected file is
1994 * Fixed a [ClientConnection] parsing bug. The port was never
1995 parsed correctly thus resulting to port 0. Affected file
1996 silcd/serverconfig.c.
1998 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1999 argument and did not set the broadcast packet flag. Affected
2000 file silcd/packet_send.c. Fixed same bug in the function
2001 silc_server_send_notify as well.
2003 * If we receive NEW_ID packet for our own ID in the server, ignore
2006 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2010 * Removed the nickname from the Private Message Payload.
2011 Updated the code and the protocol specs.
2013 * Updated protocol specs for submitting to the IETF.
2015 * Tweaked the Random Number Generator a bit. Affected file
2016 lib/silccrypt/silcrng.c. Exported a new function
2017 silc_rng_[global]_add_noise which can be used to add more
2020 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2022 * Do not parse packets with different timeout when protocol
2023 is active -> may cause problem with rekey. Affected file
2026 * When server receives signoff notify it must not create
2027 new channel key if the client is on any channels since the
2028 sender of the signoff notify will create it.
2030 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2032 * Added printing of error messages during SKE protocol from the
2033 failure packet sent by server during SKE. Affected file
2036 * Removed the client's failure_callback handling with timeout
2037 and handle it immediately when received.
2039 * The SKE library returned wrong type in SUCCESS and FAILURE
2040 packets. They must be 32 bit MSB not 16 bit MSB.
2042 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2044 * Ok, rewrote the logic of the re-key and now it seems to work.
2045 I tested it on high traffic with frequent re-keys without
2046 problems. Added hmac_receive (and renamed hmac to hmac_send)
2047 in SilcClientConnection in lib/silcclient/client.h and
2048 in SilcIDListData in silcd/idlist.h. Also, removed the
2049 SilcPacketParserContext's cipher and hmac fields as they are
2050 not needed anymore and actually caused some problems when
2051 the ciphers and hmac's changed underneath the packet parser.
2053 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2055 * If re-key protocol is active then process the incoming packets
2056 synchronously since we must assure that icoming packets encrypted
2057 with the old key is processed before the new keys is set to
2058 use. This is true other packets than for REKEY packets.
2059 Affected file silcd/server.c. The same was done to client library
2060 as well, affected file lib/silcclient/client.c.
2062 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2064 * Fixed bug in client and server to accept the force send if
2065 the packet is send from silc_[server/client]_packet_process
2066 function. Otherwise the packets are never delivered, oops.
2068 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2070 * Disable force sending of packets when REKEY protocol is active.
2071 We must assure that no packet is sent directly when rekey is
2072 performed. All packets must be sent through packet queue.
2073 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2074 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2075 function is silc_[server/client]_packet_send_real to check
2078 * Replaced the SIM paths from example config files to
2079 /usr/local/modules. Also, make install creates now
2080 /usr/local/silc/logs directory to hold all the SILC server
2083 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2085 * Made the configure.in.pre work on Solaris. Patch by salo.
2087 * Made all ciphers compatible with non-x86 machines. Defined
2088 CBC mode macros into lib/silccrypt/ciphers_def.h.
2090 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Fixed the make install.
2094 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2096 * When MAC computation fails the silc_packet_decrypt returned 0
2097 even though it was supposed to return -1. Fixed this. The
2098 affected file is lib/silccore/silcpacket.c.
2100 * Do not replace the config files in /etc/silc (in make install)
2101 if they already exist. Affected file ./Makefile.am.
2103 * Do not send re-key packets immediately but through packet queue.
2104 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2106 * Changed silc_net_check_host_by_sock to return FALSE if the
2107 IP/DNS could not be resolved. Though, it returns the IP address
2108 now even if it could not resolve it (but returns also FALSE).
2109 Affected file lib/silcutil/silcnet.[ch].
2111 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2113 * Added silc_pkcs_decode_identifier to decode the public key's
2114 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2115 Added also silc_pkcs_free_identifier. Added also new context
2116 SilcPublicKeyIdentifier.
2118 * Added -S option to the silc client. It is used to dump the
2119 contents of the specified public key file.
2121 * Changed the PKCS api to return the public key length when
2122 setting the public key.
2124 * Fixed a fatal bug in the public and private key file loading.
2125 Affected file lib/silccrypt/silcpkcs.c.
2127 * Execute the packet parsing for client with zero (0) timeout
2128 if the protocol is active. Affected file silcd/server.c.
2130 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2132 * Made the key generation options to the silcd program. Added
2133 -C option, equivalent to client's option.
2135 * Added new [ServerKeys] config section to the server. It
2136 configures the server's public and private key.
2138 * Defined generic Public Key Payload into the protocol
2139 specification to send specific type of public keys and
2142 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2143 public key or certificate.
2145 * Implemented the GETKEY command to the server and to the
2146 client library and on user interface.

2154 * Added SilcServerRekey context into silcd/idlist.h.
2156 * Added the PFS support as defined in the specification to the
2157 SKE protocol. Affected files lib/silcske/*.c.
2159 * Added `ske_group' field to the SilcServerRekey context to hold
2160 the number of the SKE group that is used with PFS in re-key.
2161 Affected file silcd/idlist.h.
2163 * Added PFS re-key support to the server. Affected file is
2166 * Added silc_protocol_cancel to cancel execution of the next
2167 state of the protocol. Affected file is
2168 lib/silccore/silcprotocol.[ch].
2170 * Added the re-key support with and without PFS to the client
2171 library. Re-key is performed once in an hour, by default.
2173 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2174 Added silc_client_rekey_callback and silc_client_rekey_final.
2175 Affected files are lib/silcclient/protocol.[ch] and
2176 lib/silcclient/client.[ch].
2178 * Removed the `hmac_key' and `hmac_key_len' fields from the
2179 SilcClientConnection structure; not needed. Affected file is
2180 lib/silcclient/client.h.
2184 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2186 * Do not ask whether user wants to use the negotiated private key
2187 for private messages, just use it. Affected file is
2188 silc/local_command.c.
2190 * Added `send_enc_key' and `enc_key_len' fields to the
2191 SilcIDListData structure since they are needed in the re-key
2192 phase. Affected file is silcd/idlist.[ch].
2194 * Implemented the simple re-key protocol into the server.
2195 Affected files silcd/server.c and silcd/protocol.[ch]. The
2196 re-key will be performed once in an hour, by default.
2198 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2199 Added silc_server_rekey, silc_server_rekey_callback and
2200 silc_server_rekey_final.
2202 * Removed Tunneled flag from the protocol. Updated the code
2203 and the specifications.
2205 * Adde `pfs' field to the SilcIDListData to indicate whether
2206 the PFS is to be performed in the re-key. Affected file is
2209 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2211 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2212 int64 of at least the xintXX size. If void * is less that 4
2213 bytes uint32 * will be used. Defined bool as boolean.
2215 * Changed _ALL_ unsigned long and unsigned int to uint32,
2216 unsgined short to uint16 in the source tree.
2218 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2219 not handle clients that has entry->data.registered == FALSE.
2220 They are not in the network anymore. Affected file is
2223 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2225 * Implemented the sending of the SERVER_SIGNOFF notify in the
2226 server. Affected file is silcd/server.c.
2228 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2229 Added also silc_notify_payload_encode_args into the
2230 lib/silccore/silcnotify.[ch].
2232 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2233 Affected file silcd/packet_receive.c.
2235 * Implemented the SERVER_SIGNOFF notify handling in the client
2236 library. Affected file lib/silcclient/client_notify.c. Also,
2237 implemnted the printing of the SERVER_SIGNOFF info to the
2238 application. Affected file silc/client_ops.c.
2240 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2241 if the deleting was successful. Affected file silcd/idlist.[ch].
2243 * Added support for public key authentication in the connection
2244 authentication protocol in the client library. Affected file
2245 lib/silcclient/protocol.c.
2247 * Changed the server's silc_idlist_get_clients_by_* interface
2248 to support already allocated array so that new entries may be
2249 added to pre-allocated array. Affected file silcd/idlist.[ch].
2250 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2251 and command replies.
2253 * All command reply functions in the server now calls the
2254 pending command callback even if error occured. This way the
2255 error will be delivered to the client as well. Affected files
2256 silcd/command.c and silcd/command_reply.c.
2258 * Fixed INFO command to return local server's info if no server
2259 was provided. Affected file lib/silcclient/command.c.
2261 * Removed RESTART command for good. Updated the code and the
2264 * Rewrote parts of the task system. It is a bit simpler now.
2265 Removed unsued task priorities. The affected files are
2266 lib/silcutil/silctask.[ch].
2268 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2270 * Moved the USERS printing from the library to the application.
2271 Affected files lib/silcclient/command.c and silc/client_ops.c.
2273 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2277 * Added channel key re-key support. The re-key is perfomed
2278 only by the router and is done once in an hour. Added `rekey'
2279 field to the SilcChannelEntry in the server. Affected files
2280 silcd/server.c and silcd/idlist.h.
2282 * Added silc_task_unregister_by_context into the file
2283 lib/silcutil/silctask.[ch].
2285 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2287 * Added SILC_UMODE_GONE mode to indicate when the client is not
2288 present in the SILC network. Added also support to the local
2289 command AWAY that will set this mode. Added support of showing
2290 "xxx is gone" in WHOIS command. The USERS command shows the
2291 gone status as well.
2293 * Fixed setting server and router operator privileges in the
2294 server's UMODE command. Affected file silcd/command.c.
2296 * Merged the SKE KE1 and KE2 payloads into one payload. The
2297 new KE payload is equivalent to the old KE2 payload.
2299 Cleaned up the SKE Start Payload parsing. It now uses the
2300 simple buffer unformatting to do the parsing. A lot faster
2303 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2304 to the SKE that is used to indicate whether both of the SKE
2305 parties should perform authentication. By default only the
2306 responder performs authentication. By setting this flag also
2307 the initiator must do authentication. By default it is unset
2308 since in normal SKE case, client to server connection, only
2309 the responder should do authentication. When doing SKE between
2310 two clients both should perform authentication. Updated the
2311 code and the protocol specs.
2313 * A little fix to IDENTIFY command in the server. Search the
2314 client first by hash not nickname. Affected file is
2317 * Fixed the silc_client_close_connection to support closing
2318 the client to client connections wihtout deleting too much
2319 data. Affected file lib/silcclient/client.c.
2321 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2322 are received if protocol used to be active but is not anymore
2323 the application would crash due to NULL pointer dereference.
2324 Affected files silcd/server.c and lib/silcclient/client.c.
2326 * Added `hash' field to the SilcClientConnection to include
2327 the hash function negotiated in the SKE protocol.
2329 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2330 to set the channel founder authentication data. A client can
2331 claim the founder rights later by providing the authentication
2332 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2333 This way the channel founder can regain the channel founder
2334 privileges even it is left the channel. This works only on
2335 local server and the client must be connected to the same
2336 server to be able to regain the founder rights. Updated the
2337 protocol specs accordingly.
2339 Added support to the CMODE command in the client to set the
2340 founder auth data. Read the README to see how to set it.
2342 Added support to the CUMODE command to claim the founder
2343 rights. Read the README to see how to do it.
2345 Added support for the founder authentication to the Channel
2346 Entry in the server. Affected file silcd/idlist.h.
2348 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2349 server's CMODE command. Affected file silcd/command.c.
2351 * Added the following new functions into lib/silccore/silcauth.[ch]:
2352 silc_auth_get_method and silc_auth_get_data.
2354 * The server now saves the remote hosts public key to the
2355 SilcIDListData pointer. Affected file silcd/protocol.c.
2357 * The normal server now does not remove the channel entry from
2358 the cache if the founder authentication data is set. It used
2359 to remove it if the founder was the last one on the channel on
2360 the server and left the channel. The auth data is saved and
2361 if the channel is re-joined later the old entry is used with
2362 the old auth data. Affected files silcd/command_reply.c and
2365 * Removed the `pkcs' field from the SilcIDListData structure
2366 in the server; it is not used. Affected file silcd/idlist.h.
2368 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2370 * Fixed packet processing on slow links. Partial packets were
2371 never re-processed because the incoming data buffer was cleared
2372 by the application. Application must not directly clear the
2373 sock->inbuf, the packet processing routines handle it. Fixed
2374 this in client library and in server.
2376 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Fixed the WHOIS and IDENTIFY send reply function to really
2379 check whether to send list or just one entry. Affected file
2382 * Cleaned up the LEAVE command's channel key distribution. The
2383 affected file silcd/command.c.
2385 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2386 can enforce the channel mode as well. In that case the ID
2387 includes the ID of the server. The code now enforces the
2388 mode change if the router have different mode than the server.
2390 * The notify client operation with CMODE_CHANGE notify can now
2391 return NULL client_entry pointer if the CMODE was not changed
2392 by client. Application must check for this.
2394 * Added <Server ID> argument to INFO command to support server
2395 info fetching by Server ID.
2397 * Added silc_server_announce_get_channel_users to get assembled
2398 packets of channel users of the specified channel. Affected
2399 file silcd/server.[ch].
2401 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2402 was freed underneath the ID Cache.
2404 * Re-announce clients when the server received CHANNEL_CHANGE
2405 notify from the router. Affected file silcd/packet_send.c.
2407 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2409 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2410 crashed since it did not handle the fact that there is no cipher
2411 called "3" and didn't check the error condition. Now fixed.
2413 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2414 flag. It can be used to send message requests.
2416 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2418 * Implemented the RESTART command in the client.
2420 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2421 notice type messages. Added notice printing to the user
2424 * The channel keys are not re-generated if the channel's mode
2425 is PRIVKEY, ie private key on the channel exists. Affected
2426 files silcd/server.c and silcd/command.c.
2428 * Fixed a little bug in channel message delivery when channel
2429 private keys are set in the server. Affected file is
2430 silcd/packet_send.c.
2432 * Changed the setting on channel->on_channel = TRUE from the
2433 silc_client_save_channel_key to the JOIN command reply. The
2434 key payload is not received if the private channel key is set.
2435 Affected file lib/silcclient/command_reply.c and the
2436 lib/silcclient/client_channel.c.
2438 * When the CMODE_CHANGE notify is sent and the channel private
2439 key mode is removed the channel key must be re-generated in
2440 other cells as well. Added this support for the router in the
2441 silcd/packet_receive.c.
2443 * Added new local command NOTICE to send notice message on
2444 channel. Affected file silc/local_command.[ch].
2446 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2448 * Added new local command ME to the client. It is used to send
2449 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2450 some action. Affected file silc/local_command.[ch].
2452 * Changed channel_message and private_message client operations
2453 to deliver the message flags to the application. Added also
2454 the `flags' arguments to the silc_client_send_channel_message
2455 and silc_client_send_private_message functions. Affected file
2458 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2460 * Redefined the Private Message Payload to support private message
2461 keys and to support the new private message flags. Updated
2462 the protocol specs. Flags makes it possible to have for example
2463 CTCP style messages.
2465 * Added new type SilcPrivateMessagePayload and defined an API
2466 for it in the lib/silcclient/silcprivate.[ch].
2468 * Tested private message private keys successfully. Tested the
2469 private message key set, unset and list commands with the new
2472 * Redefined the Channel Message Payload to include the channel
2473 message flags (equal with private message flags) to support
2474 for example CTCP style messages.
2476 * Defined some of the message (for channel and private message)
2477 flags. Updated the protocol specs and added the flags to the
2478 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2480 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2482 * Added SilcKeyAgreementStatus type to the key agreement routines
2483 to indicate the current status and error if one occured.
2484 The status types are defined in the lib/silcclient/silcapi.h.
2486 * Added new local command KEY that is used to set and unset private
2487 keys for channels, set and unset private keys for private messages
2488 with remote clients and to send key agreement requests and
2489 negotiate the key agreement protocol with remote client. The
2490 key agreement is supported only to negotiate private message keys,
2491 it currently cannot be used to negotiate private keys for channels,
2492 as it is not convenient for that purpose.
2494 * Fixed a minor pending callback setting bug in the function
2495 silc_client_get_client_by_id_resolve, now the function works.
2496 Affected file lib/silcclient/idlist.c.
2498 * Added function silc_net_get_local_port to get local bound
2499 port by socket. Added to lib/silcutil/silcnet.[ch].
2501 * Added `sockets' and `sockets_count' fields to the SilcClient
2502 object. They hold the sockets of the listenning sockets in
2503 the client. Listenning sockets may be for example the key
2504 agreement server. Affected file lib/silcclient/client.[ch].
2505 Added functions the silc_client_add_socket and the
2506 silc_client_del_socket. They are exported to the application
2509 * Added ~./silc/clientkeys to support other client's public keys.
2511 * Renamed verify_server_key client operation to verify_public_key
2512 and added one argument to indicate the type of the connection
2513 (server, client etc.).
2515 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2517 * Added silc_server_connection_auth_request to handle the
2518 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2519 silcd/packet_receive.[ch].
2521 * Added silc_server_send_connection_auth_request into the
2522 silcd/packet_send.c to send the connection auth request packet.
2524 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2527 * Fixed the public key authentication in responder side in the
2528 server. The `auth_data' pointer includes the SilcPublicKey
2529 not the path to the public key. Affected file silcd/protocol.c.
2531 * Implemented the public key authentication in the initiator side
2532 in the server. Affected file silcd/protocol.c.
2534 * Removed the [RedirectClient] config section from the server
2535 configuration. Is not needed and I don't want to implement it.
2537 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2539 * Cleaned up the CMODE command in the server. It now works
2540 correctly and supports all the modes defined in the protocol.
2541 Affected file is silcd/command.c.
2543 * Added `hmac_name' field to the SilcChannelEntry in the server
2544 to hold the default HMAC of the channel. It can be set when
2545 creating the channel (with JOIN command). Affected files
2548 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2549 type to indicate the change of the current cipher and hmac
2550 on the channel. Client can safely ignore the <cipher> argument
2551 (if it chooses to do so) since the CHANNEL_KEY packet will
2552 force the channel key change anyway. The <hmac> argument is
2553 important since the client is responsible of setting the new
2554 HMAC and the hmac key into use.
2556 * Fixed the CMODE command in the client library as well.
2558 * Tested CMODE command in router environment successfully.
2560 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2562 * Show the version of the remote client (or server) when connecting
2563 to the server. It is logged to the log file. Affected file
2564 is silcd/protocol.c.
2566 * Fixed the KILLED notify handling in the client library. The
2567 client must be removed from all channels when receiving the
2570 Also, do not remove the client entry when giving the KILL
2571 command but when the KILLED notify is received.
2573 * Removed silc_idlist_find_client_by_nickname from the server.
2574 Not needed anymore. Affected files silcd/idlist.[ch].
2576 * Implemented the CHANNEL_CHANGE notify type handling to the
2577 server. Affected file silcd/server.c.
2581 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Added silc_server_send_notify_invite to send the INVITE
2584 notify between routers.
2586 * Implemented the INVITE command correctly to the server.
2588 * Implemented the INVITE notify type handling in the server.
2590 * Implemented the INVITE command to the client library and on the
2593 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2595 * Added function silc_server_get_client_resolve to find the
2596 client entry by ID from all ID lists and then resolve it
2597 (using WHOIS) if it cannot be found. Affected file is
2600 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2602 * Implemented the BAN command to the client library.
2604 * The JOIN command in the server now checks the invite list
2607 * Changed the silc_command_reply_payload_encode_va and the
2608 silc_command_payload_encode_va to support that if argument is
2609 NULL it ignores and checks the next argument. Affected file
2610 lib/silccore/silccommand.c.
2612 * Added silc_server_send_notify_ban to send the BAN notify
2613 type between routers.
2615 * Chaned the silc_notify_payload_encode to support that if
2616 argument is NULL it ignores and checks the next argument.
2617 Affected file lib/silccore/silcnotify.c.
2619 * Tested ban lists in router environment successfully.
2621 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2623 * Implemented BAN command to the server, in silcd/command.[ch].
2625 * Removed the BAN and INVITE_LIST modes from the CMODE command
2628 * Added function silc_string_match to regex match two strings.
2629 Affected files lib/silcutil/silcutil.[ch].
2631 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2633 * Redefined parts of the SilcChannelEntry in the server to support
2634 the new ban and invite lists.
2636 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2638 * Redefined the INVITE command. The same command can be used to
2639 invite individuals to the channel but also to manage the invite
2640 list of the channel (to add to and remove from the invite list).
2641 Updated the protocol specs.
2643 * Added new command SILC_COMMAND_BAN that can be used to manage
2644 the ban list of the channel. Updated the protocol specs.
2646 * Removed the channel modes: the SILC_CMODE_BAN and the
2647 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2648 in the CMODE command. The equivalent features are now available
2649 using INVITE and BAN commands. Updated the protocol specs.
2651 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2652 in the network about change in the current ban list. The notify
2653 type is not used by the client.
2655 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2656 support the invite lists.
2658 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2660 * Added new function silc_string_regexify that converts string
2661 including wildcard characters into regex string that can
2662 be used by the GNU regex library. Added into the file
2663 lib/silcutil/silcutil.[ch].
2665 Added silc_string_regex_combine to combine to regex strings
2666 into one so that they can be used as one regex string by
2667 the GNU regex library. Added into the file
2668 lib/silcutil/silcutil.[ch].
2670 Added silc_string_regex_match to match two strings. It returns
2671 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2673 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2675 * Imported GNU regex to the soruce tree into lib/contrib.
2676 Fixed some compiler warning from the regex.c.
2678 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2680 * Fixed MOTD command in the server to work in router environment.
2682 * Fixed the MOTD command in the client library to support
2683 the server argument in the command.
2685 * Added `nickname_len' argument to the silc_idlist_add_client
2686 in the server, as the `nickname' argument may be binary data
2689 * Added silc_idlist_get_channels to return all channels from
2692 * Implemented LIST command to the server. Affected file is
2695 * Implemented the LIST command to the client library and on the
2698 * Added [<user count>] argument to the LIST command reply.
2699 With private channels the user count is not shown.
2701 * Updated TODO and README.
2703 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2705 * The client entry's data.registered must be TRUE even with
2706 global client entry on global client list. The data.registered
2707 is used to check whether the client is anymore in the network,
2708 for example with WHOWAS command so it must be valid.
2710 * Fixed the WHOWAS command in the server. It now actually works
2711 in router environment. Added function into silcd/command_reply.c
2712 silc_server_command_reply_whowas_save.
2714 * Added silc_idlist_purge function to the silcd/idlist.c
2715 to periodically purge the ID Cache.
2717 * Fixed INFO command in the server. It works now in router
2718 environment. Added <server name> argument to the INFO command
2719 reply. Updated the protocol specs.
2721 * Fixed minor bug in silc_idcache_purge to not purge if the
2722 expire value is zero.
2724 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2725 they were buggy because of the WHOWAS information.
2727 * Fixed local command MSG to handle the async resolving of
2728 the remote client properly. It used to fail the first MSG.
2729 Affected file silc/local_command.c.
2731 * Added `data_len' field to SilcIDCache context.
2733 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2735 * Update TODO. Todo in commands in the server.
2737 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2739 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2740 used by routers as broadcast packet to inform other routers
2741 about the changed user mode.
2743 Implemented the notify handling in the server. Affected file is
2744 silcd/packet_receive.c. Added the function
2745 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2747 * Added new generic Channel Payload and deprecated the New Channel
2748 Payload. The New Channel Payload is now the generic Channel
2751 * Added new argument `mode' to the silc_server_send_new_channel
2752 as it is required in the Channel Payload now.
2754 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2755 and created a new and real SilChannelPayload to represent the
2756 new generic Channel Payload. Implemented the encode/decode
2757 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2759 * Added silc_server_get_client_channel_list to return the list
2760 of channels the client has joined for WHOIS command reply.
2761 Affected file silcd/server.[ch].
2763 * Implemented the channel list sending in the WHOIS command reply
2764 in server and in the client.
2766 Implemented the channel list displaying on the user interface
2767 as well. Affected file silc/client_ops.c.
2769 * Added silc_channel_payload_parse_list to parse list of Channel
2770 Payloads. It returns SilcDList list of SilcChannelPayloads.
2771 Client for example can use this function to parse the list of
2772 channels it receives in the WHOIS command reply. The caller
2773 must free the list by calling silc_channel_payload_list_free.
2774 Affected files lib/silccore/silcchannel.[ch].
2776 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2778 * Added one new argument <user mode> to the WHOIS command reply
2779 to return the mode of the user in SILC. Updated the protocol
2782 Implemented it to the server and client.
2784 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2786 * Fixed the mode printing on the user interface on joining.
2787 Affected file silc/client_ops.c.
2789 * Implemented the UMODE command and user modes in general to the
2790 client library and to the user interface.
2792 * Implemented the UMODE command to the server.
2794 * The server now sends UNKNOWN_COMMAND error status if client sends
2795 unknown command. Affected file silcd/command.c.
2797 * All server commands now handle the command identifier the right
2798 way when sending the command reply to the client. The client can
2799 use to identify the command replies with the identifier.
2801 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2803 * Added silc_server_get_client_route to resolve the route to
2804 the client indicated by the client ID. Affected file is
2807 * Added silc_server_relay_packet as general function to relay
2808 packet to arbitrary destination. This deprecates functions
2809 like _send_private_message_key, _relay_notify etc. Affected
2810 file is silcd/packet_send.[ch].
2812 Removed silc_server_send_key_agreement,
2813 silc_server_send_private_message_key and
2814 silc_server_packet_relay_notify functions from the file
2815 silcd/packet_send.[ch].
2819 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2820 server. Affected file silcd/packet_receive.[ch].
2822 * Implemented the KILL command to the client. Implemented the
2823 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2824 Affected files lib/silcclient/command[_reply].c and
2825 lib/silcclient/client_notify.c. Implemented the KILL notify
2826 printing in the user inteface.
2828 * Fixed a lot silc_parse_nick memory leaks from the client
2829 library in the file lib/silcclient/command.c.
2831 * Changed the silc_server_send_notify_on_channels's `sender'
2832 argument from SilcSocketConnection to SilcClientEntry to
2833 check the sender as entry and not as connection object and not
2834 to send to the client provided as argument. The affected file
2835 is silcd/packet_send.[ch].
2837 * The notify packets that are destined directly to the client used
2838 to not to be processed by the server. Now changed that and the
2839 server processes all notify packets. After relaying the packet
2840 to the client the notify packet is processed in the server.
2842 * The silc_server_free_client_data now checks whether there is
2843 pending outgoing traffic for the client and purges the data to
2844 the network before removing the client entry.
2846 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2848 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2849 an client is killed from the SILC Network. Updated the protocol
2852 Added new function silc_server_send_notify_killed to the
2853 silcd/packet_send.[ch].
2855 * Added function silc_server_packet_relay_notify to relay notify
2856 packets that are destined directly to a client. In this case
2857 the server does not process the notify packets but merely relays
2858 it to the client. Affected file silcd/packet_send.[ch].
2860 Added also silc_server_packet_process_relay_notify to check
2861 whereto relay the notify. Affected file is
2862 silcd/packet_receive.[ch].
2864 * Implemented the KILL command to the server.
2868 * Added the backup schema desgined last fall to the protocol
2869 specs for everyone to see. The specification is in the
2870 *-spec-xx.txt draft and the packet type definitions for the
2871 backup routers is in *-pp-xx.txt draft. Thusly, added also
2872 new packet type SILC_PACKET_CELL_ROUTERS.
2874 * A big security problem in the implementation discovered. The
2875 signoff of an client did not cause new channel key generation
2876 which it of course should've done. The channel keys must be
2877 always re-generated when client leaves (or signoffs) the channel.
2878 The silc_server_remove_from_channels funtion now handles
2879 the channel key re-generation.
2881 * Added `sender' argument to the silc_server_send_notify_on_channels
2882 to not to send the client provided as argument. Affected file
2883 silcd/packet_send.[ch].
2885 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2887 * Implemented OPER and SILCOPER commands into the server and
2890 * Added silc_auth_verify and silc_auth_verify_data to verify
2891 the authentication directly from the authentication payload.
2892 It supports verifying both passphrase and public key based
2893 authentication. Affected file lib/silccore/silcauth.[ch].
2895 * Added `hash' field to the SilcIDListData structure. It is the
2896 hash negotiated in the SKE protocol. Affected file is
2899 * Slight redesigning of the SilcAuthPayload handling routines.
2900 Do not send SilcPKCS but SilcPublicKey as argument.
2902 * Implemented the public key authentication support to the
2903 serverconfig. The public key is loaded from the provided path
2904 and saved as authentication data to void * pointer. Thus,
2905 changed the unsigned char *auth_data to void *auth_data;
2907 * Fixed SHUTDOWN command to send the reply before the server
2908 is shutdown. :) Affected file silcd/command.c.
2910 * Fixed fatal bug in CONNECT command. The hostname was invalid
2911 memory and server crashed. Affected file silcd/command.c.
2913 * Fixed fatal bug in CLOSE command. The server_entry became
2914 invalid but was referenced later in the command. Affected file
2917 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2919 * Fixed fatal bug in failure packet handling. Server ignored
2920 the failure and thus crashed when it came.
2924 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2926 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2927 that the command may be executed only once in (about) 2 seconds.
2928 The old SILC_CF_LAG flag is same but allows command bursts up
2929 to five before limiting.
2931 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2932 server code. Various commands now includes the CF_LAG_STRICT
2933 flag to disallow any kind of miss-use of the command.
2935 * Fixed the silc_buffer_unformat to not to allocate any data
2936 if the length of the data is zero. It used to allocate the
2937 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2939 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2941 * Changed the format of AdminConnection configuration section
2942 in the server. Added username of the admin to the format.
2943 Affected files silcd/serverconfig.[ch].
2945 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2946 to return admin configuration data by host, username and/or
2949 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2951 * Implemented WHOWAS command to the server. Added the functions:
2953 silc_server_command_whowas_parse,
2954 silc_server_command_whowas_send_reply,
2955 silc_server_command_whowas_from_client and
2956 silc_server_command_whowas_from_server
2958 * Added <Client ID> argument to the WHOWAS command reply. Updated
2959 the protocol specs accordingly.
2961 * Implemented WHOWAS command and command_reply to the client
2964 Implemented the WHOWAS printing on the user interface.
2966 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2968 * Added new argument to the WHOWAS command reply, the real name.
2969 It is an optional argument. Updated the protocol specs.
2971 * Added SilcIDCacheDestructor callback that is registered when
2972 the SilcIDCache is allocated. The callback is called when
2973 an cache entry in the ID Cache expires, or is purged from the
2974 cache. Added into lib/silccore/idcache.[ch].
2976 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2977 to destruct the client entries when the cache entry expires.
2978 Other ID Cache's in server and in the client library ignores
2981 * If the ID Cache entry's `expire' field is zero then the entry
2982 never expires. Added boolean `expire' argument to the
2983 silc_idcache_add function in the lib/silccore/idcache.[ch].
2984 If it is TRUE the default expiry value is used.
2986 * Added silc_server_free_client_data_timeout that is registered
2987 when client disconnects. By default for 5 minutes we preserve
2988 the client entry for history - for WHOWAS command.
2990 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2992 * Added support to the server to enforce that commands are not
2993 executed more than once in 2 seconds. If server receives
2994 commands from client more frequently, timeout is registered
2995 to process the commands. Affected file silcd/command.c.
2996 Added new function silc_server_command_process_timeout.
2998 * Changed NICK_NOTIFY handling in client library to check that
2999 if the client's nickname was changed, so there is no need to
3000 resolve anything from the server.
3002 * Removed error printing from the WHOIS and IDENTIFY commands.
3003 If error occurs then it is ignored silently in the client library.
3004 The application, however, may map the received error to
3005 human readable error string. The application currently maps
3006 the NO_SUCH_NICKNAME error to string.
3008 * Made the command status message public to the application. Moved
3009 them from lib/silcclient/command_reply.c to
3010 lib/silcclient/command_reply.h. The application can map the
3011 received command status to the string with the
3012 silc_client_command_status_message function.
3014 * Added check to the server to check that client's ID is same
3015 as the Source ID in the packet the client sent. They must
3018 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3020 * Added dist-bzip hook to the Makefile.am to make bzip2
3021 compressed distributions.
3023 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3025 * Server now enforces the maximum length for the nickname and
3026 the channel as protocol specification dictates. 128 bytes for
3027 nickname and 256 bytes for channel name.
3029 * Moved the WHOIS printing to the application. The client libary
3030 does not print out the WHOIS information anymore, the application
3031 must do it. Renamed silc_client_command_reply_whois_print to
3032 the silc_client_command_reply_whois_save.
3034 The client's idle time is also sent to the application now, and
3035 the idle is shown on screen.
3037 * Added silc_client_command_reply_identify_save to save the
3038 received IDENTIFY entries.
3040 * Do not check for channel private keys in message sending and
3041 reception if the channel does not have the PRIVKEY mode set.
3042 Affected file lib/silclient/client_channel.c.
3044 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3046 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3047 just surfaced after chaning the JOIN procedure.
3049 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3051 * Added silc_client_get_clients_by_list to get client entries
3052 from Client ID list, that is returned for example by JOIN
3053 and USERS command replies. The application should use this
3054 function for example when JOIN command reply is received to
3055 resolve the clients already on the channel (library does not
3056 do that anymore as USERS command reply is not used in the JOIN
3057 procedure anymore). Affected files lib/silcclient/silcapi.h and
3058 lib/silcclient/idlist.c.
3060 * JOIN command reply and USERS command reply returns now SilcBuffer
3061 pointers instead of unsigned char pointers when returning
3062 the client list and mode list.
3064 * Added <Client ID> argument to the JOIN command reply, mainly
3065 for the server to identify for which client the command was
3066 originally sent. Updated protocol specs accordingly.
3068 * Added SilcDlist private_key pointer to the SilcChannelEntry
3069 in the client to support the channel private keys. Affected
3070 file is lib/silcclient/idlist.h.
3072 * Added SilcChannelPrivateKey argument to the function
3073 silc_client_send_channel_message so that application can choose
3074 to use specific private ke if it wants to. If it is not provided,
3075 the normal channel key is used, unless private keys are set.
3076 In this case the first (key that was added first) is used
3077 as the encryption key.
3079 * Implemented the support for channel private key handling.
3080 Implemented the following functions:
3082 silc_client_add_channel_private_key,
3083 silc_client_del_channel_private_keys,
3084 silc_client_del_channel_private_key,
3085 silc_client_list_channel_private_keys and
3086 silc_client_free_channel_private_keys
3088 Affected file lib/silcclient/client_channel.c.
3090 * Added the support for the private keys in the channel message
3091 sending and encryption and in the message reception and
3092 decryption. Affected funtions are
3093 silc_client_send_channel_message and silc_client_channel_message.
3095 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Added SKE's key verify callback to the client library's
3098 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3100 * Removed the statement that server (or router) must send USERS
3101 command reply when joining to the channel so that the client
3102 knows who are on the channel. Instead, the client list and
3103 client's mode list is now sent in the JOIN command reply to the
3104 client who joined channel. This is better solution.
3106 * Added function silc_server_get_users_on_channel and function
3107 silc_server_save_users_on_channel to the silcd/server.[ch].
3109 * Removed function silc_server_command_send_users from the
3112 * Do not show topic on the client library anymore. The topic is
3113 sent in the command reply notify to the application and the
3114 application must show the topic now.
3116 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3118 * Added client searching by nickname hash into the IDENTIFY and
3119 WHOIS commands in the server as they were clearly missing from
3120 them. Affected file is silcd/command.c.
3122 * Fixed a bug in private message receiving in the client library.
3123 The remote ID was freed and it wasn't supposed, now it is
3126 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3128 * Minor fix to the channel payload; allocate the data area, as it
3129 needs to be of specific length.
3131 * If the key agreement port is zero then the operating
3132 system will define the bound port. Affected files are
3133 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3135 * Added new function silc_channel_payload_decrypt into the file
3136 lib/silccore/silcchannel.[ch].
3138 * Moved the channel message etc, check from silc_packet_decrypt
3139 to applications. The library calls now a generic
3140 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3141 when the packet is either normal or special. This was done to
3142 allow more wide range of checking that was not allowed when
3143 the code was in library. Now applications can do virtually any
3144 checks to the packet and return to the library the decision how
3145 the packet should be processed. Affected files are
3146 lib/silccore/silcpacket.[ch].
3148 Added silc_server_packet_decrypt_check to the server and
3149 silc_client_packet_decrypt_check to the client library.
3151 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3152 to send with specified source and destination information.
3154 * Channel message delivery between routers was broken after the
3155 channel key distribution was fixed earlier. The channel key
3156 was used be to distributed to other routers as well which is not
3157 allowed by the protocol. Now this is fixed and channel keys
3158 really are cell specific and the channel message delivery between
3159 routers comply with the protocol specification.
3161 * Fixed various commands in server to check also the global list
3162 for the channel entry and not just the local list. The affected
3163 file silcd/command.c.
3165 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3167 * Added assert()s to buffer formatting and unformatting routines
3168 to assert (if --enable-debug) when error occurs. Affected
3169 file: lib/silcutil/silcbuffmt.c.
3171 * Changed to auto-reconnect to check whether the remote host is
3172 router and register the re-connect timeout if it is. It used
3173 to check that whether we are normal server, but router must do
3174 auto-reconnect with another router as well. Affected file
3177 * Removed the [<key len>] option from CMODE command as the cipher
3178 name decides the key length, nowadays. See the defined ciphers
3179 from the protocol specification.
3181 * Added [<hmac>] option to the CMODE command to define the HMAC
3182 for the channel. Added SILC_CMODE_HMAC channel mode.
3184 * Added [<hmac>] option for the JOIN command so that user can
3185 select which HMAC is used to compute the MACs of the channel
3188 * Added Hmac field to the Channel Message Payload. The integrity
3189 of plaintext channel messages are now protected by computing
3190 MAC of the message and attaching the MAC to the payload. The
3191 MAC is encrypted. Now, it is clear that this causes some
3192 overhead to the size of the packet but rationale for this is that
3193 now the receiver can verify whether the channel message decrypted
3194 correctly and also when private keys are set for the channel the
3195 receiver can decrypt the packet with several keys and check from
3196 the MAC which key decrypted the message correctly.
3198 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3199 lib/silccrypt/silccipher.[ch].
3201 * Added silc_hash_len to return the digest length into the
3202 lib/silcrypt/silchash.[ch].
3204 * Rewrote parts of Silc Channel Payload interface in the
3205 lib/silccore/silcchannel.[ch]. The encode function now also
3206 encrypts the packet and parse function decrypts it.
3208 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3210 * Fixed a minor formatting bug in the SKE's key material processing.
3211 It actually might have processed the keys wrong way resulting
3214 * Redefined the mandatory HMAC algorithms and added new algorithms.
3215 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3216 and hmac-md5 truncated to 96 bits. The mandatory is now
3217 hmac-sha1-96. Rest are optional (including the one that used
3218 to be mandatory). Rationale for this is that the truncated HMAC
3219 length is sufficient from security point of view and can actually
3220 make the attack against the HMAC harder. Also, the truncated
3221 HMAC causes less overhead to the packets. See the RFC2104 for
3224 * Added new [hmac] configuration section. The SKE used to use
3225 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3226 is of course wrong. The official names that must be proposed in
3227 the SKE are the ones defined in the protocol specification
3228 (hmac-sha1-96 for example). The user can configure any hmac
3229 using any hash function configured in the [hash] section. At
3230 least, the mandatory must be configured.
3232 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3234 * Added HMAC list to the SKE proposal list. It has now both
3235 hash algorithm list and HMAC list. This makes the protocol
3236 incompatible with previous versions. The SKE now seems to work
3237 the way it is supposed to work, for the first time actually.
3239 * Defined plain Hash algorithms to the protocol specification.
3242 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3244 * Implemented support for key agreement packets into the server.
3245 Added functions silc_server_key_agreement and
3246 silc_server_send_key_agreement. Other than these functions,
3247 server has nothing to do with this packet.
3249 * Added support for private message key packets into the server.
3250 Added functions silc_server_private_message_key and
3251 silc_server_send_private_message_key.
3255 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3256 called in the protocol's final callback instead in the END
3257 protocol state. This makes a little more sense and in the same
3258 time in client we can use the same protocol routines for normal
3259 key exchange and to key agreement packet handling as well.
3261 * Added to both client's and server's KE protocol context the
3262 SilcSKEKeyMaterial pointer to save the key material. We will
3263 bring the key material to the protocol's final callback by doing
3264 this. The final callback must free the key material.
3266 * Added SKE's packet_send callback into client's KE protocol
3267 context so that the caller can choose what packet sending function
3268 is used. This way we can use different packet sending when
3269 doing normal SKE when doing key agreement packet handling (in
3270 the key agreement packet handling we do not want to encrypt
3273 * Implemented the responder side of the key agreement routines
3274 in the client. The client can now bind to specified port and
3275 accept incoming key negotiation. The key material is passed
3276 to the application after the protocol is over.
3278 * Implemented the processing of incoming Key Agreement packet
3279 in the client. Added function silc_client_key_agreement to
3282 * Implemented the intiator side of the key agreement routines
3283 in the client. The client can now initiate key agreement with
3284 another remote client. The key material is passed to the
3285 application after the protocol is over.
3287 * Created client_keyagr.c to include all the key agreement
3290 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3291 SILC_TASK_CALLBACK except that it is not static.
3293 * Created client_notify.c and moved the Notify packet handling
3294 from the client.[ch] into that file.
3296 * Created client_prvmsg.c and moved all private message and
3297 private message key routines from the client.[ch] into that file.
3299 * Create client_channel.c and moved all channel message and
3300 channel private key routines from the client.[ch] into that file.
3302 * Changed silc_client_get_client_by_id_resolve to resolve with
3303 WHOIS command instead of IDENTIFY command, in the file
3304 lib/silclient/idlist.c.
3306 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3308 * Implemented the SKE's responder side to the Client library.
3310 * When FAILURE is received to the protocol do not trust it
3311 blindly. Register a timeout to wait whether the remote closes
3312 the connection as it should do it, only after that process the
3313 actual failure. This was changed to both client and server.
3315 * Added client_internal.h to include some of the structures
3316 there instead of client.h in lib/silcclient/.
3318 * Added function silc_task_unregister_by_callback to unregister
3319 timeouts by the callback function.
3321 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3323 * Some "Incomplete WHOIS info" errors has been appearing on the
3324 log files. Took away the entry->userinfo check from WHOIS
3325 reply sending. The entry->userinfo is now " " if client did not
3326 provide one. I thought this was fixed earlier but something
3327 is wrong still. Let's see if the error still appears.
3329 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3331 * Fixed a minor bug in the login when the channel key is
3332 re-generated in the server. It used to generate the key in
3333 wrong order and thus caused problems in the channel traffic.
3335 * Fixed a minor bug in channel key distsribution after
3336 KICK command. The key was not sent to the router even though
3339 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3341 * Added silc_ske_process_key_material_data as generic routine
3342 to process any key material as the SILC protocol dictates. The
3343 function is used by the actual SKE library but can be used by
3344 applications as well. This relates to the private message keys
3345 and the channel private keys since they must be processed the
3346 same way the normal SILC session keys. The protocol dictates
3347 this. Affected files: lib/silcske/silcske.[ch].
3349 Added also silc_ske_free_key_material to free the
3350 SilcSKEKeyMaterial structure.
3352 * Defined silc_cipher_set_key function to set the key for
3353 cipher without using the object's method function. The affected
3354 files: lib/silccrypt/silccipher.[ch].
3356 * Implemented silc silc_client_add_private_message_key,
3357 silc_client_add_private_message_key_ske,
3358 silc_client_del_private_message_key,
3359 silc_client_list_private_message_keys and
3360 silc_client_free_private_message_keys functions in the
3363 Added functions silc_client_send_private_message_key to send
3364 the Private Message Key payload and silc_client_private_message_key
3365 to handle incoming Private Message Key payload.
3367 * Added Cipher field to the Private Message Key payload to set
3368 the cipher to be used. If ignored, the default cipher defined
3369 in the SILC protocol (aes-256-cbc) is used.
3371 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3373 * Removed lib/silcclient/ops.h file.
3375 Redefined parts of the SILC Client Library API. Created new
3376 file silcapi.h that deprecates the ops.h file and defines the
3377 published Client Library API. Defined also private message key
3378 API and channel private key API into the file.
3380 This is the file that the application must include from the
3381 SILC Client Library. Other files need not be included by
3382 the application anymore.
3384 * Added new key_agreement client operation callback and also
3385 defined the Key Agreement library API for the application.
3387 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3389 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3390 is used by clients to request key negotiation between another
3391 client in the SILC network. If the negotiation is started it
3392 is performed using the SKE protocol. The result of the
3393 negotiation, the secret key material, can be used for example
3394 as private message key.
3396 Implemented the Key Agreement payload into the files
3397 lib/silccore/silauth.[ch].
3399 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3401 * Redefined ciphers for the SILC protocol. Added some new ciphers
3402 and defined the key lengths for the algorithms. Changed the
3403 code accordingly. The default key length is now 256 bits.
3405 * Fixed SKE key distribution function silc_ske_process_key_material
3406 when the key length is more than 128 bits. The default key
3407 length in SILC is now 256 bits.
3409 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3410 to indicate unsupported algorithm.
3412 * Renamed rijndael.c to aes.c and all functions as well.
3414 * Fixed a long standing channel key setting bug in client library.
3415 Weird that it has never surfaced before.
3417 * Fixed bug in channel deletion. If the entire channel is removed
3418 then it must also delete the references of the channel entry
3419 from the client's channel list as the client's channel entry and
3420 the channel's client entry share same memory.
3422 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3424 * Implemented CONNECT and SHUTDOWN commands in the client.
3426 * Implemented CLOSE command to the client.
3428 * Added the function silc_idlist_find_server_by_name into the
3429 files silcd/idlist.[ch].
3431 Added the function silc_idlist_find_server_by_conn into the
3432 files silcd/idlist.[ch].
3434 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * DIE command was renamed to SHUTDOWN. Updated the both code
3439 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3440 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3442 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3445 * Added function silc_server_create_connection function to create
3446 connection to remote router. My server implementation actually
3447 does not allow router to connect to normal server (it expects
3448 that normal server always initiates the connection to the router)
3449 so the CONNECT command is only good for connecting to another
3452 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3454 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3455 or some other client was kicked from the channel.
3457 Implemented the handling of the notify type to both client
3460 Implemented silc_server_send_notify_kicked to send the KICKED
3461 notify. It is used to send it to the server's primary router.
3463 * Implemented the KICK command into server and client.
3465 * Added `query' argument to the silc_idlist_get_client function
3466 to indicate whether to query the client from server or not if
3469 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3470 to indicate that the client is not channel founder.
3474 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3476 * Removed the rng context from SilcPacketContext structure and
3477 changed that the packet routine uses the Global RNG API.
3479 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Added support for quit message that client can "leave" on the
3482 channel when it quits the SILC. It is ditributed inside the
3483 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3485 Added silc_server_free_client_data that will take the
3486 signoff message as argument.
3488 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3490 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3492 * Updated parts of the protocol specification to keep it up
3495 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3497 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3498 payloads in one packet.
3500 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3501 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3502 use now the new List flag.
3504 * Also deprecated the following packet types: REPLACE_ID,
3505 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3507 * Added list support for Notify packet in server.
3509 * Added silc_server_send_notify_channel_change to send the
3510 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3511 the silc_server_send_replace_id.
3513 * Added silc_server_send_notify_nick_change to send the
3514 NICK_CHANGE notify type. Deprecates the function
3515 silc_server_send_replace_id.
3517 * Added silc_server_send_notify_join to send the JOIN notify type.
3518 Deprecates the function silc_server_send_new_channel_user.
3520 * Added silc_server_send_notify_leave to send LEAVE notify type.
3521 Deprecates the function silc_server_send_remove_channel_user.
3523 * Added silc_server_send_notify_cmode and
3524 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3525 types. Deprecates the silc_server_send_set_mode function.
3527 * Added SERVER_SIGNOFF notify type to indicate that server has
3528 quit. This means that all clients on the channel from that
3529 server will drop. This can be also used when netsplit happens.
3531 Deprecated REMOVE_ID packet type since it is not needed anymore
3534 Added silc_server_send_notify_server_signoff to send the
3535 SERVER_SIGNOFF notify type. Deprecates the function
3536 silc_server_send_remove_id.
3538 Added also silc_server_send_notify_signoff to send the
3539 SIGNOFF notify type.
3541 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3542 SILC protocol from this day on. Changed the protocol
3543 specification as well.
3545 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3546 notify type. It is used between routers to notify about
3547 topic changes on a channel.
3549 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3552 * Partly updated the protocol specification to comply with the
3553 changes now made. It is still though a bit outdated.
3555 * The JOIN notify type now takes one extra argument <Channel ID>.
3556 The packet used to be destined to the channel but now the
3557 JOIN type may be sent as list thus it is impossible to
3558 destine it to any specific channel. By adding this argument
3559 it is again possible.
3561 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3563 * Added CREDITS file. The CHANGES and CREDITS file will appear
3564 in the distribution as well.
3566 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3568 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3569 types in the server's silcd/packet_receive.c.
3571 * Implemented CMODE and CUMODE to work in router environment.
3573 * Fixed minor encoding and decoding buglet from the
3574 lib/silccore/silcmode.c.
3576 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3579 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3581 * Changed all SilcConfigServer* and silc_config_server* to
3582 SilcServerConfig* and silc_server_config*, respectively.
3585 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3587 * Associated the ID (client or server ID) to the Authentication
3588 Payload to avoid any possibility of forging. Updated the
3589 protocol specification and the code accordingly.
3591 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3593 * The RSA key length is now save to the RsaKey context in the
3594 key generation process in lib/silccrypt/rsa.c. The key length
3595 is now used to figure out the maximum size of the block allowed
3596 to be encrypted/signed.
3598 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3599 is equivalent to the silc_mp_mp2bin but does not allocate any
3602 * Changed silc_mp_mp2bin API to take length argument. If it is
3603 non-zero then the buffer is allocated that large. If zero, then
3604 the size is approximated using silc_mp_sizeinbase, which however
3607 * Created Global RNG API which is global RNG that application can
3608 initialize. After initializing, any routine anywhere in the
3609 code (including library) can use RNG without allocating a new
3610 RNG object. This was done to allow this sort of use of the
3611 RNG in code that has no chance to allocate RNG object. All
3612 applications currently allocate this and many routines in the
3613 library use this. Affected file lib/silccrypt/silcrng.[ch].
3615 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3616 it to use the Global RNG API.
3618 * Defined Authentication Payload into protocol specification that
3619 is used during SILC session to authenticate entities. It is
3620 used for example by client to authenticate itself to the server
3621 to obtain server operator privileges.
3623 Implemented this payload into the lib/silccore/silcauth.[ch].
3624 Implemented also routines for public key based authentication
3625 as the new protocol specification dictates.
3627 Moved definitions of different authentication methods from
3628 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3630 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3631 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3632 silc_pkcs_verify_with_hash functions into the file
3633 lib/silccrypt/silcpkcs.[ch].
3635 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3637 * The client entry's userinfo pointer must be always valid.
3638 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3639 will fail since it requires the userinfo. Now, the userinfo
3640 is allocated as "" if actual userinfo does not exist. Actually,
3641 it must exist and it is totally Ok to drop client connections
3642 that does not announce the userinfo. However, we will make
3643 this workaround for now.
3645 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3646 to return the remote port by socket.
3648 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3650 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3651 SILC_SERVER_PENDING_EXEC and added an new macro
3652 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3653 data or when error occurs while processing the pending command.
3655 Added new argument `destructor' into silc_server_command_pending
3656 and to the SilcServerCommandPending object. This destructor is
3657 now called after calling the pending callback or if error occurs
3658 immediately. If error occurs the actual pending callback won't
3659 be called at all - only the destructor. The destructor may be
3660 NULL if destructor is not needed.
3662 All this applies for client library code as well. Similar
3663 changes were made there as well for the pending commands.
3665 In the client, the application must now allocate the
3666 SilcClientCommandContext with the silc_client_command_alloc
3669 * Added reference counter to the SilcServerCommandContext. Added
3670 function silc_server_command_alloc and silc_server_command_dup
3673 Same type of functions added to the client library for the same
3676 * Removed the cmd_ident from IDListData away since it is now
3677 global for all connections. It is the command identifier used
3678 in command sending and with pending commands. The affected file
3681 * Added reference counter to the SilcSocketConnection objecet to
3682 indicate the usage count of the object. The object won't be
3683 freed untill the reference counter hits zero. Currently only
3684 server uses this, and client ignores it. The client must be
3685 set to use this too later. The affected files are
3686 lib/silccore/silcsockconn.[ch]. Added also the function
3687 silc_socket_dup to increase the reference counter.
3689 This was mainly added because it is possible that the socket
3690 is removed underneath of pending command or other async
3691 operation. Now it won't be free'd and proper DISCONNECTING
3692 flags, etc. can be set to avoid sending data to connection that
3693 is not valid anymore.
3695 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3696 the connection. After that it sets SILC_SET_DISCONNECTED.
3697 It is, however, possible that the socket data is not still freed.
3698 The silc_server_packet_process now checks that data is not
3699 read or written to connection that is DISCONNECTED. The socket
3700 get's freed when the reference counter hits zero.
3702 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3704 * Changed the client operation API: channel_message operation's
3705 `sender' is now the client entry of the sender, not the nickname
3706 and the `channel' is the channel entry, not the channel name.
3708 In the private_message operation the `sender' is now also the
3709 client entry of the sender not the nickname.
3711 Affected file is lib/silcclient/ops.h and all applications
3712 using the client operations.
3714 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3716 * Moved the calling of ops->connect() from connect_to_server_final
3717 into receive_new_id functin since that is the point when the
3718 client is actually allowed to send traffic to network. The
3719 affected file is lib/silcclient/client.c.
3721 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3723 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3724 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3725 (if needs broadcasting) instead of broadcasting the packets one
3726 by one which would make a burst in the network traffic.
3728 * Added `broadcast' argument to the functions in silcd/server.[ch]
3729 silc_server_create_new_channel[_with_id] to indicate whether
3730 to send New Channel packet to primary router.
3732 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3734 * Added new function into the silcd/server.[ch] files:
3735 silc_server_create_new_channel_with_id to create new channel with
3736 already existing Channel ID.
3738 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3739 lib/silccore/silcpacket.h. This packet is used t send list of
3740 Set Mode payloads inside one packet. Server uses this to set
3741 the modes for the channels and clients on those channels, that it
3742 announced to the router when it connected to it. The protocol
3743 specification has been updated accordingly.
3745 * The silc_server_new_channel did not handle the packet coming
3746 from normal server as it normally does not send that. However,
3747 when it announces its channels it does send it. Implemented
3748 the support for that.
3750 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3751 into the file lib/silccore/id.h.
3753 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3755 * Fixed memory leaks in the functions silc_idlist_del_client,
3756 silc_idlist_del_channel and silc_idlist_del_server in the file
3757 silcd/idlist.c. All of those leaked like a sieve.
3759 * Fixed some small memory leaks in the client's function
3760 silc_client_notify_by_server.
3762 * Added functions into silcd/server.c: silc_server_announce_clients,
3763 silc_server_announce_channels and silc_server_announce_server.
3764 These functions are used by normal and router server to announce
3765 to its primary router about clients, channels and servers (when
3766 router) that we own. This is done after we've connected to the
3769 These functions effectively implements the following packet types:
3770 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3771 and SILC_PACKET_NEW_ID_LIST.
3773 * Added new functions into the silcd/packet_receive.[ch]:
3774 silc_server_new_id_list, silc_server_new_channel_list and
3775 silc_server_new_channel_user_list to handle the incoming
3776 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3778 * Added support of changing Channel ID in the function
3779 silc_server_replace_id. If the server that announces a channel
3780 to the router already exists in the router (with same name but
3781 with different Channel ID), router is responsible to send
3782 Replace ID packet to the server and force the server to change
3783 the Channel ID to the one router has.
3785 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3786 client that the Channel ID has been changed by the router. The
3787 normal server sends this to the client. Client must start using
3788 the new Channel ID as the channel's ID.
3790 Implemented handling of this new type into lib/silcclient/client.c
3791 into the function silc_client_notify_by_server.
3793 * Added new function silc_idlist_replace_channel_id into the files
3794 silcd/idlist.[ch] to replace the Channel ID.
3796 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3798 * Call silc_server_command_identify_check always when processing
3799 the IDENTIFY command in silcd/command.c
3801 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3803 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3804 send keepalive packets. The packet can be sent by clients,
3805 servers and routers.
3807 Added function silc_socket_set_heartbeat into the file
3808 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3809 If not set, the heartbeat is not performed. The actual
3810 heartbeat is implemented in the low level socket connection
3811 library. However, application is responsible of actually
3814 Added silc_server_send_heartbeat to send the actual heartbeat
3815 packet into silcd/packet_send.[ch]. Server now performs
3816 keepalive with all connections.
3818 * Added silc_task_get_first function into lib/silcutil/silctask.c
3819 to return the timeout task with shortest timeout. There was a bug
3820 in task unregistration that caused problems. TODO has been
3821 updated to include that task system must be rewritten.
3823 * The client library will now resolve the client information when
3824 receiving JOIN notify from server for client that we know but
3825 have incomplete information.
3827 * Rewrote parts of silc_server_remove_from_channels and
3828 silc_server_remove_from_one_channel as they did not remove the
3829 channel in some circumstances even though they should've.
3831 * Encryption problem encountered in server:
3833 The LEAVE command used to send the Channel Key packet to the
3834 router immediately after generating it. However, the code
3835 had earlier sent Remove Channel user packet but not immediately,
3836 ie. it was put to queue. The order of packets in the router
3837 was that Channel Key packet was first and Remove Channel User
3838 packet was second, even though they were encrypted in the
3839 reverse order. For this reason, MAC check failed. Now, this
3840 is fixed by not sending the Channel Key packet immediately but
3841 putting it to queue. However, this is more fundamental problem:
3842 packets that are in queue should actually not be encrypted
3843 because packets that are sent immediately gets encrypted
3844 actually with wrong IV (and thus MAC check fails). So, packets
3845 that are in queue should be encrypted when they are sent to
3846 the wire and not when they put to the queue.
3848 However, the problem is that the current system has not been
3849 designed to work that way. Instead, the packet is encrypted
3850 as soon as possible and left to the queue. The queue is then
3851 just purged into wire. There won't be any fixes for this
3852 any time soon. So, the current semantic for packet sending
3855 o If you send packet to remote host and do not force the send
3856 (the packet will be in queue) then all subsequent packets to the
3857 same remote host must also be put to the queue. Only after the
3858 queue has been purged is it safe again to force the packet
3861 o If you send all packets immediately then it safe to send
3862 any of subsequent packets through the queue, however, after
3863 the first packet is put to queue then any subsequent packets
3864 must also be put to the queue.
3866 Follow these rules and everything works fine.
3868 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3870 * Added new function silc_server_remove_clients_by_server to
3871 remove all client entries from ID list when the server connection
3872 is lost. In this case it is also important to invalidate all
3873 client entires as they hold the invalid server entry. This
3874 fixes fatal bug when server has lost connection and will reconnect
3877 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3879 * Made some sanity checks to silc_server_daemonise like to check
3880 whether the requested user and group actually exists.
3882 * Added sanity check to SKE's silc_ske_responder_finish to check
3883 that the public and private key actually is valid.
3885 * Invalidate the client's nickname when receiving Replace ID
3886 packet and the Client ID is being replaced. This means that the
3887 server will query the nickname if someone needs it (client)
3890 * Sort the ID Cache in client library when the ID Cache data
3891 has changed (needs sorting).
3893 * Do not allow for SILC client to create several connections to
3894 several servers. The client does not support windows right now
3895 and generating multiple connections causes weird behaviour.
3897 Irssi-silc client does support windows and can handle several
3898 connections without problems, see: www.irssi.org and SILC plugin.
3900 * Fixed some places where client was added to the IDList. The
3901 rule of thumb is following (in order to get everything right):
3902 If the client is directly connected local client then the
3903 `connection' argument must be set and `router' argument must be
3904 NULL to silc_idlist_add_client function. If the client is not
3905 directly connected client then the `router' argument must
3906 bet set and the `connection' argument must be NULL to the
3907 silc_idlist_add_client function.
3909 * The funtion silc_server_packet_send_local_channel actually did
3910 not check whether the client was locally connected or not. It
3911 does that now. Fixed a bug related to LEAVE command.
3913 * Fixed Remove Channel User payload parsing bug in server's
3914 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3916 * The server's silc_server_save_channel_key now checks also the
3917 global ID list for the channel as it might not be in the local
3918 list. Fixed a bug related to LEAVE command.
3920 * Is this the end of the [<unknown>] buglet that has been lurking
3921 around for a long time? A little for loop fix in server's
3922 silc_server_command_whois_parse that is used by both IDENTIFY
3923 and WHOIS command. At least, this was a clear bug and a cause
3924 of one type of [<unknown>] buglet.
3926 * WHOIS and IDENTIFY commands call the function
3927 silc_server_command_[whois/identify]_check function even if
3928 we are not router server.
3930 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3932 * Added --with-gmp configuration option. If set the GMP
3933 is always compiled in the SILC source tree. If not set then
3934 it is checked whether the system has the GMP3 installed. If
3935 it has then the GMP won't be compiled (the system's headers
3936 and library is used), if it doesn't have it then the GMP is
3937 compiled in the SILC source tree.
3939 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3941 * Changed RSA private exponent generation to what PKCS #1
3942 suggests. We try to find the smallest possible d by doing
3943 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3944 not security fix but optimization.
3946 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3948 * Added new config entry [Identity] to fork the server and run
3949 it as specific user and group. A patch from Bostik.
3951 * Imported Dotconf configuration library into lib/dotconf.
3952 This will be used to create the SILC configuration files later.
3953 It will appear in the distsribution after this commit.
3955 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3957 * A big code auditing weekend happening. Auditing code for
3958 obvious mistakes, bugs and errors. Also, removing any code
3961 Removed files for being obsolete:
3963 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3964 inline in the file lib/silcutil/silcbuffer.h)
3966 o lib/silcutil/silcbufutil.c (the header has inline versions)
3968 Changed code to fix possible error conditions:
3970 o The buffer formatting routines now check that the destination
3971 buffer really has enough space to add the data. This applies for
3972 both buffer formatting and unformatting
3973 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3974 unformatting was changed to accomodate following rules:
3975 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3976 sent to the function while XXX_*STRING will not allocate or copy
3977 the data into the buffer. Instead it sets the pointer from the
3978 buffer into the pointer sent as argument (XXX_*STRING used to
3979 require that the pointer must be allocated already). This change
3980 makes this whole thing a bit more consistent and more optimized
3981 (note that the data returned in the unformatting with XXX_*STRING
3982 must not be freed now). The routines return now -1 on error.
3984 o Tried to find all code that use buffer_format and buffer_unformat
3985 and added return value checking to prevent formatting and
3986 especially unformatting errors and possible subsequent fatal
3989 o Changed ske->x and ske->KEY to mallocated pointers in
3990 lib/silcske/silcske.h. Fixed possible data and memory leak.
3992 o Added return value checking to all *_parse* functions. Fixed
3993 many memory leaks as well.
3995 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3996 so that buffer overflows would not happen. All code now also
3997 checks the return value as it can fail.
3999 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4001 * Added reconnection support to server if the normal server looses
4002 its connection to the router (for example if router is rebooted).
4003 The server performs normal reconnection strategy implemented
4004 to the server. Affected file silcd/server.c.
4006 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4008 * Added new packet type SILC_PACKET_SET_MODE that is used to
4009 distribute the information about changed modes (for clients,
4010 channels and clients channel modes) to all routers in the
4011 network. Updated the protocol specification accordingly.
4013 Added functions into silcd/packet_send.c and
4014 silcd/packet_receive.c: silc_server_send_set_mode,
4015 silc_server_set_mode.
4017 Added new files silcmode.[ch] into lib/silccore that implements
4018 the encoding and decoding of Set Mode Payload. Added new type
4019 SilcSetModePayload. Moved the definitions of different modes
4020 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4022 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4024 * Oops, a little mistake in server's connection authentication
4025 protocol. The protocol is not ended with FAILURE but with
4026 SUCCESS if the authentication is Ok. :) Affected file is
4029 * Implemented NICK_CHANGE notify handling in server in the file
4030 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4031 the local clients on the channel. After the changing nickname
4032 in router environment snhould work and the [<unknown>] nickname
4033 should appear no more.
4035 The silc_server_replace_id function that receives the Replace ID
4036 payload now sends the NICK_CHANGE notify type also in the file
4037 silcd/packet_receive.c
4039 * Changed WHOIS and IDENTIFY command to support the maximum amount
4040 of arguments defined in protocol specs (3328 arguments). This
4041 fixed a bug that caused problems when there were more than three
4044 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Added extra parameter, command identifier, to the
4047 silc_client_send_command so that explicit command identifier
4050 Changed that ID list routines uses specific command identifier
4051 when sending WHOIS/IDENTIFY requests to the server so that they
4052 can be identified when the reply comes back.
4054 Affected files lib/silcclient/command.[ch],
4055 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4057 * Added `sender' argument to silc_server_packet_send_to_channel
4058 to indicaet the sender who originally sent the packet to us
4059 that we are now re-sending. Ignored if NULL. Affected file
4060 silcd/packet_send.[ch].
4062 * Added some server statistics support in silcd/server_internal.h
4063 SilcServerStatistics structure and around the server code. Also
4064 send some nice statistics information when client is connecting
4067 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4069 * Fixed channel ID decoding in server's JOIN command reply in
4070 silcd/command_reply.c
4072 * Fixed braodcasting of replace ID payload to not to send it if
4073 we are standalone server in silcd/packet_receive.c.
4075 * Fixed all channel message sending routines to not to send
4076 packets to clients that has router set, since they are routed
4077 separately in the same function earlier. Affects file
4078 silcd/packet_send.c and all channel packet sending functions.
4080 * In USERS reply, res_argv[i] are not allocated, the table
4081 is allocated. Thus changed that free the table, not its
4084 * In server's whois_check and identify_check if the client is
4085 locally connected do not send any WHOIS commands - they are not
4088 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4090 * Fixed some minor bugs in client when sending WHOIS command. The
4091 arguments was in wrong order.
4093 * Removed statis function add_to_channel from server in
4094 silcd/command.c that was previously used with the joining but
4097 * Tested USERS command in router environment successfully with two
4098 routers, two servers and two clients.
4100 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4102 * Reorganized the USERS command and command reply in client library
4103 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4104 When the command is given by user we register a pending command
4105 callback that will reprocess the command after the reply has been
4106 received from the server. When reprocessing the packet we then
4107 display the information. Thus, the USERS information is displayed
4108 now in the command callback instead of in the command reply
4109 callback. The processing of the command is same as previously
4110 when server has sent the command reply in the JOINing process.
4112 * Added to USERS command in silcd/command_reply.c to join the client,
4113 we didn't use to know about, to the channel after we've created
4114 a client entry for it. Also, for clienet we did know already still
4115 check whether it is on the channel or not and add it if not.
4117 * Removed silc_server_command_join_notify as the function and its
4120 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4122 * Changed the client's pending command handling to the same as the
4123 server's pending command handling. It is also now possible to
4124 execute command reply functions from other command reply
4125 function as the function callbacks for commands and command
4126 replies are one and same. The pending commands are not static
4127 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4128 in client connection context. Thus, pending commands are server
4129 connection specific as it is convenient.
4131 Changed the function silc_client_command_pending and
4132 silc_client_command_pending_del and added new function
4133 silc_client_command_pending_check. Removed the
4134 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4137 * Added cmd_ident, current command identifier, to the client
4138 connection context in lib/silcclient/client.h to keep track on
4139 command identifiers used in command sending. Client's command reply
4140 function handling now supports the mandatory command identifiers.
4142 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4143 funtions in client to fully support pending command callbacks.
4145 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4146 as one of the arguments to the application in the command reply
4149 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4150 before first releasing SILC but came back. Now it is removed again
4151 and should come back nomore. The FORWARDED flag was used only
4152 by the JOINing procedure by forwarding the command packet to router.
4153 Now, the JOINing procedure has been changed to more generic (due
4154 to various router environment issues) and FORWARDED is not needed
4155 anymore for anything. The protocol specification is yet to be
4158 Now, removed silc_server_packet_forward from server and the flag
4159 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4161 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4163 * Renamed NAMES command to USERS command. The NAMES was named that
4164 due to historical reasons. Now it is renamed. Also, rewrote
4165 parts of the USERS command. The nickname list is not sent anymore
4166 by the server. Only Client ID and mode lists are sent in the USERS
4167 command. Changed this also to the protocol specification.
4169 The client now resolves the names and stuff after it receives
4170 the USERS list from the server when joining to the channel.
4172 * WHOIS and IDENTIFY commands has been changed to support multiple
4173 Client ID's per command. One can now search for multiple users
4174 in the network by sending only one WHOIS or IDENTIFY command.
4175 Changed the code and the protocol specifications.
4177 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4178 uses silc_server_command_whois_parse to parse the request. */
4180 * If normal server, do not parse the WHOIS and IDENTIFY requests
4181 before sending it to the router. Saves some time.
4183 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Fixed JOIN command on client library. Wrong number of arguments
4186 used to crash the client.
4188 * Added silc_server_channel_has_global function to check whether
4189 channel has global users or not.
4191 * Added silc_server_channel_has_local function to check whether channel
4192 has locally connected clients on the channel.
4194 * The silc_server_remove_from_one_channel now checks whether the
4195 channel has global users or not after given client was removed from
4196 the channel. It also checks whether the channel has local clients
4197 on the channel anymore. If it does not have then the channel entry
4198 is removed as it is not needed anymore.
4200 * The silc_server_notify now checks on JOIN notify whether the joining
4201 client is one of locally connected or global. If it is global then
4202 the channel has now global users on the channel and that is marked
4203 to the channel entry. Also, it now saves the global client to
4204 global list who is joining and JOINs it to the channel. This is
4205 for normal server, that is.
4207 Changed silc_server_send_notify_on_channel,
4208 silc_server_packet_relay_to_channel and
4209 silc_server_packet_send_to_channel check if we are normal server
4210 and client has router set (ie. global client) do not send the
4211 message to that client, as it is already routed to our router.
4213 * Implemented LEAVE notify type handling in silc_server_notify
4216 * Tested LEAVE command in router environment successfully. Tested
4217 with two routers, two servers and two clients.
4221 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4223 * Implemented SIGNOFF notify type handling in silc_server_notify
4226 * silc_server_remove_id now removes the client entry from all channels
4227 it has joined and thusly sends SIGNOFF notify type.
4229 * Rewrote the NAMES list generation in server by removing two excess
4230 loops. The lists are created now inside one loop.
4232 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4234 * silc_server_remove_channel_user checks now also global list
4235 for channel and client.
4237 * silc_server_new_channel_user checks now both local and global
4238 list for channel and client. Fixed a bug in client id decoding.
4239 Used to decode wrong buffer.
4241 * silc_server_channel_message checks now both local and global
4242 list for channel entry.
4244 * Tested channel joining (hence JOIN) in router environment
4245 successfully. Tested with two routers, two servers and two
4248 * Tested channel message sending in router environment successfully.
4250 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4252 * Added silc_server_save_channel_key into server.[ch] to save the
4253 received channel key in Channel Key payload processing. It is
4254 also used in JOIN command reply handling.
4256 Equivalent function silc_client_save_channel_key added into
4257 client.[ch] into client library.
4259 * Changed JOIN command reply to send information whether the channel
4260 was created or not (is existing already) and the channel key
4261 payload. Changed protocol specs accordingly.
4263 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4264 the request was sent by ID and not by nickname. Crashed on
4267 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4269 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4270 now correctly save the received data.
4272 * silc_server_free_sock_user_data now notifies routers in the
4273 network about entities leaving the network.
4275 At the same time implemented functions silc_server_remove_id
4276 and silc_server_send_remove_id to receive and send REMOVE_ID
4277 packets. The packet is used to notify routers in the network
4278 about leaving entities. The ID removed will become invalid in
4281 * Added function silc_idlist_del_server into server. Removes and
4282 free's server entry from ID list.
4284 * silc_server_private_message function now checks, if we are router,
4285 that the destination ID really is valid ID, naturally.
4287 * In router when NEW_ID packet is received (for new client) the
4288 hash of the Client ID is saved in the ID Cache but the
4289 client->nickname is set to NULL, instead of putting the hash
4292 IDENTIFY command now also checks that client->nickname must be
4293 valid. If it is not if will request the data from the server who
4294 owns the client. Added new function
4295 silc_server_command_identify_check.
4297 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4298 to set the command to already allocated Command Payload.
4300 * Tested private message sending in router environment with two
4301 routers, two servers and two clients. Fixed minor bugs and now
4304 * Fixed segfault from client's NAMES command. Used to crash if
4307 * Forwarded packets must not be routed even if it is not destined
4308 to the receiver. Changed server code comply with this.
4310 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4312 * Added `require_reverse_mapping' boolean value to ServerParams
4313 structure. If TRUE (not default) the server will require that
4314 the connecting host has fully qualified domain name.
4316 If the reverse mapping is not required and hostname could not be
4317 found the IP address is used as hostname.
4319 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4321 * Implemented version string checking to both client and server.
4322 The check is incomplete currently due to the abnormal version
4323 strings used in development version of SILC.
4325 * Changed all command functions in server to use the new
4328 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4330 * Changed char *data to unsigned char *data in ID Cache system to
4331 support binary data as ID Cache data. Changed code to support
4332 binary data in lib/silccore/idcache.c.
4334 * Renamed silc_server_packet_relay_command_reply to
4335 silc_server_command_reply as it is normal packet receiving
4336 function. Rewrote the function to accept command replys for
4337 servers and not only for clients.
4339 * Mark remote router always as registered server if we are connecting
4340 to it. Otherwise, commands sent by the router to us are ignored.
4342 * All ID List find routines now returns the ID Cache Entry pointer
4343 as well if requested.
4345 * WHOIS command works now in router environment, tested with two
4346 routers, two servers and two clients.
4348 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4349 in router environment (as it is almost equivalent to WHOIS) but
4350 hasn't been tested thoroughly. Added new functions:
4352 silc_server_command_identify_parse
4353 silc_server_command_identify_send_reply
4354 silc_server_command_identify_from_client
4355 silc_server_command_identify_from_server
4357 * Disabled route cache adding because adding two different ID's with
4358 same IP replaces the old cache entry thus giving wrong route.
4359 The entry->router->connection is always the fastest route anyway
4360 so route cache may not be needed. Of course, new routes maybe
4361 established after receiving the ID when the entry->router->connection
4362 might not be anymore the most optimal.
4364 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4366 * Add route cache for received ID for fast routing.
4368 * Added silc_server_packet_route to route received packet on router
4369 that is not destined to us.
4371 * Renamed silc_server_get_route to silc_server_route_get.
4373 * Added id_string and id_string_len fields into SilcServer to
4374 include encoded ServerID for fast comparing without excess
4375 encoding of the ID's.
4377 * Cleaned up WHOIS command on server side. Added following static
4380 silc_server_command_whois_parse
4381 silc_server_command_whois_check
4382 silc_server_command_whois_send_reply
4383 silc_server_command_whois_from_client
4384 silc_server_command_whois_from_server
4386 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4387 arguments in command replies. All command functions should be
4388 updated to use this macro.
4390 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4392 * Minor typo fixes on command reply handling on server.
4394 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4396 * Added silc_server_command_add_to_channel internal routine to add
4397 the client to the channel after router has created the channel and
4398 sent command reply to the server.
4400 * Added generic silc_server_send_command to send any command from
4403 * Use static buffer with ID rendering instead of duplicating data.
4405 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4407 * Fixed a channel user mode bug when joining to a channel server gave
4408 everybody channel founder rights, oops.
4410 * We mark ourselves as the router of the incoming server connection
4411 if we are router ourselves. This way we can check in some packet
4412 sending functions whether it is locally connected server. For
4413 incoming router connections we put NULL.
4415 * For router sending packets locally means now always sending the
4416 packet cell wide; to local clients and local servers. For normal
4417 server sending packet locally means sending it to only local
4420 * Fixed the JOIN command to really work in router environment. If the
4421 channel is created it is always created by the router. Router is
4422 also responsible of making the initial joining to the channel,
4423 sending JOIN notify to the sending server and distributing
4424 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4425 does not exist server doesn't do anything else but forward the
4426 command to the router which performs everything.
4428 * Added silc_server_send_channel_key function to send the Channel Key
4431 * Added silc_server_create_channel_key to create new channel key. The
4432 channel key is now re-generated everytime someone joins or leaves
4433 a channel, as protocol dictates. Note: channel->key_len is the
4436 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4438 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4439 packet_receive.[ch] to separate packet sending and receiving
4440 routines. The server.[ch] now includes everything else including
4441 actual packet processing (writing and reading data) and other
4444 Renamed silc_server_private_message_send_internal to
4445 silc_server_send_private_message. The routine is still though
4446 used only to relay private messages as server does not send
4447 private messages itself.
4449 Renamed silc_server_new_channel to silc_server_create_new_channel
4450 and added new function sicl_server_new_channel that handles the
4451 incoming New Channel packet. Added also new sending function
4452 silc_server_send_new_channel to send New Channel Payload.
4454 * Added new function silc_server_notify to process incoming notify
4455 packet to the server/router. Server may then relay the notify
4456 to clients if needed.
4458 * Added new function silc_server_new_channel_user to process incoming
4459 New Channel User packet. Router will redistribute the packet and
4460 send JOIN notify to its local clients and locally connected servers
4461 if needed. Normal server will send JOIN notify to its local client
4462 on same channel when received this packet. Added also corresponding
4463 sending function silc_server_send_new_channel_user to sent the
4466 * Added boolean route argument to send_notif_to_channel and
4467 packet_send_to_channel functions to attempt to route the packet
4468 if it is TRUE and send only locally if it is FALSE.
4470 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4472 * silc_server_replace_id now broadcasts the received replace ID
4473 packet if it is not broadcast packet already. The router must
4474 broadcast to inform other routers about changed ID.
4476 * Added backpointer to server's router into SilcServer context in
4477 silcd/server_internal.h.
4479 * Fixed silc_server_packet_broadcast to send correct broadcast
4482 * The channel key is now distributed to the local client as soon
4483 as it is received from the router (in router environment) so that
4484 no other packet may be sent for the channel until client has
4487 * silc_server_remove_channel_user now broadcasts the received
4488 Remove Channel User packet if it is not broadcast packet already.
4489 The router must broadcast to inform other routers about removed
4492 * Added users field into SilcPacketContext that is a reference count
4493 of the context. One can increase the reference count by calling
4494 silc_packet_context_dup which is now changed to just increase the
4495 reference count instead of duplicating the data. The reference
4496 count is decresed by calling silc_packet_context_free that will
4497 free the data after the reference count hits zero.
4499 For now on the packet context and everything allocated into it
4500 (including the raw packet from network) must be freed by calling
4501 the new silc_packet_context_free function. Added also new function
4502 silc_packet_context_alloc that must be used now to allocate the
4503 context. This also means that if a routine is asynchronous from
4504 silc_[client/server]_packet_parse_type the packet context must
4505 be duplicated by calling silc_packet_context_dup. Otherwise it
4506 gets free'd after silc_[client/server]_packet_parse_type returns.
4507 Also, one must remember that if packet is duplicated then its
4508 reference count must be decresed by calling the free function as
4509 many times as it was duplicated.
4511 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4512 from both client and server.
4514 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4516 * Made joining to a channel working in router environment.
4518 * Cleaned up JOIN command on server side and create function
4519 silc_server_command_join_channel internal routine to make the
4522 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4524 * Changed silc_command_pending list to SilcDList. Also, added
4525 `ident' field to SilcServerCommandPending structure to identify
4526 the reply and to call correct callback.
4528 Added silc_server_command_pending_check function to replace the
4529 corresnponding macro. The silc_command_pending list is not
4532 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4533 to set identifier to previously allocated Command Payload. It
4534 is used to set identifier for command when resending Command
4537 * Added silc_command_payload_encode_payload to encode Command
4538 Payload buffer from SilcCommandPayload structure.
4540 * Added silc_argument_payload_encode_payload to encode Argument
4541 payload buffer from SilcArgumentPayload structure.
4543 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4545 * Changed WHOIS command to support router connection on server side.
4546 The whois request is always sent to router unless the server is
4547 standalone server. After server has received the reply from the
4548 router will it send the reply to the client.
4550 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4551 broadcast received broadcast packet. The function is used only
4552 by router. The broadcast packet is always sent to the router's
4555 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4556 render given ID to printable string, for log files for example.
4558 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4560 * Made basic router to router connections working. At least they
4561 can now connect to each other but nothing really works the way
4562 they are supposed - yet.
4564 * Added new initiator token to RouterConnection configuration
4565 file in silcd/serverconfig.[ch]. It is used to tell whether we
4566 are the initiator to the remote router or whether we'll expect
4567 the other end to connect.
4569 * Moved registering of listener task to silc_server_init, hence
4570 the server starts listenning as soon as it is run, even if it
4571 does not have connections to other routers. Let's see how well
4574 * Changed default connection retry timeouts for more suitable in
4577 * Removed cipher and such arguments from silc_idlist_add_client
4578 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4579 Added new function silc_idlist_add_data to add the keys and stuff
4582 * Added SilcIDListData structure and added it to SilcClientEntry
4583 and SilcServerEntry as their first field in the structure. This
4584 way we can explicitly cast the ID entries to the SilcIDListData
4585 structure and get common data for the entries. In past, we had
4586 to first check what type of connection it is and then cast it to
4587 correct ID entry type. Now, we can directly cast the opaque
4588 pointer to the SilcIDListData (no matter what ID entry it actually
4589 is) and get the data needed.
4591 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4594 in some circumstances even if threre were timeout tasks, though not
4595 IO tasks, but tasks anyway. Now fixed.
4597 * Defined SilcServerConnection structure to hold connection specific
4598 stuff about directly connected servers and routers. The definition
4599 is currently in silcd/server_internal.h. I thought about having
4600 a bit more important role fro this struct but for now it is used
4601 only when connecting to other server (or router actually).
4603 * Added connecting retry support in server when connecting to
4604 router(s). The retry feature implement exponential backoff
4605 algorithm. Also, added SilcServerParams structure to hold default
4606 parameters for server. For now, it include these retry settings
4607 and are hard coded. After server is moded to be as Silc Server
4608 Library this structure will be more important.
4610 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4612 * Changed client librarys channel->clients table to SilcList and
4613 changed code accordingly.
4615 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4617 * Changed client's channel table to SilcList and changed code
4618 accordingly. Also changed SilcChannelClientEntry to include back-
4619 pointer to the channel so that client entry can use that structure
4620 as list as well and we have fast cross-reference to the channel.
4621 This change dramatically decreased the complexity of channel
4622 handling with client entry and vice versa (removed one extra
4623 loop when searching for channel entry from many functions).
4625 * Changed server->sim from table to SilcDList and changed code
4628 * NAMES command can now be used from user interface. It will show
4629 the user list on the channel, neatly.
4631 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4632 Code now saves realname of the user if it becomes available.
4634 * Renamed configure.in to configure.in.pre and made ./prepare
4635 script to automatically add correct version string to
4636 configure.in which it creates from configure.in.pre.
4638 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4640 * NAMES command reply now shows users mode with the nickname when
4643 * Moved silc_client_ch[u]mode[_char] functions from
4644 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4645 place sucks, they are utility functions and should be in some
4648 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4650 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4653 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4657 * Added TRQ (efficient deque and list library) into lib/trq. This is
4658 a very good list library that is currently used in the SILC. Defined
4659 SilcList API over the library because I didn't like the API very
4660 much. See lib/trq/silclist.h for the API and examples of how to
4661 use the API. Fixed various places in the code to use the new
4662 SilcList API. The SilcList is meant for lists that has a structure
4663 already defined as a list. It is not suitable to add just some
4664 context to the list (in TRQ, the context is the list actually).
4666 So, I defined SilcDList that can be used for the purpose where
4667 predefined list structure does not exit. This can be used as
4668 such list. Now some context just can be added to the SilcDList.
4669 Currently this list is not used in the SILC just yet, though there
4670 are a lot places where this can replace dynamically allocated
4671 tables and I will fix these places, later, to use SilcDList.
4672 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4673 and use TRQ internally).
4675 Also fixed some annoying warning messages that the original TRQ
4676 code generated. Also minor changes to TRQ's Makefile.in.
4678 * Added support for querying by Client ID to both WHOIS and
4679 IDENTIFY commands into server, as required by the protocol.
4681 * Removed method function pointers from SilcBuffer structure. They
4682 weren't used to anything and just increased the context size for
4683 no good reason. This change also made silc_buffer_alloc and
4684 silc_buffer_free functions inline functions.
4686 * Disabled command flooding detection support until it's fixed so
4687 that it accepts commands in but does not execute them more than once
4690 * Added silc_net_localhost(), to return local hostname, into
4691 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4692 that must be initialized before calling silc_client_init.
4694 * Added new function: silc_server_send_notify_on_channels to send
4695 notify messages to all channels client has joined. It is assured
4696 that the message is sent only once per client.
4698 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4699 lib/silcutil/silcutil.[ch] as silc_format function. The new
4700 function is generic and is used by server as well, not only by
4701 the logging routines.
4703 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4704 the provided version string was not acceptable. Added new function:
4705 silc_ske_check_version into lib/silcske/silcske.h. The function
4706 must be implemented by the application (client or server) and it
4707 does not reside in the SKE library. The function checks the version
4708 string remote end sent.
4710 * Added back pointers (to opaque context and to SilcSocketConnection)
4711 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4713 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4714 duplicate packet context structure.
4716 * Changed `notify' client operation to send same arguments as client
4717 receives from server except for ID's. ID's are mapped to correct
4718 ID entry and that is returned. Also, if channel entry is not sent
4719 by server but the notify is for channel the channel entry is sent
4720 to application (otherwise application doesn't know that it is for
4721 channel (library gets it from packet's Destination ID)).
4723 * Added silc_client_remove_from_channels into client library to
4724 remove a client from all channels it has joined to. Used when
4725 received SIGNOFF notify from server. Added also new function
4726 silc_client_replace_from_channels to replace old ID entry with
4727 new ID entry on all channels. Used when received NICK_CHANGE
4730 * Fixed ID Cache list handling in silc_idlist_get_client in
4731 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4732 to get (or query) client by ID.
4734 * Updated TODO list.
4736 * Added connection authentication status message defined by the
4737 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4738 support for these into the code in client and server side.
4740 * Added generic function silc_client_send_command to send any command
4741 with variable argument list. Application should use this function
4742 to send commands if the command functions provided by the library
4743 does not suite for the application's user interface needs.
4745 * Added new `failure' client operation. Application is notified about
4746 received failure packet if client is executing a protocol. In this
4747 case the protocol's execution has failed.
4749 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4750 is required by the protocol.
4752 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4753 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4756 * Added status flag to SilcSKE object to indicate realtime status
4757 of the SKE protocol.
4759 * Application receives now exactly same command reply arguments as
4760 the library receives from server. However, if ID is received the
4761 corresponding ID entry is returned to the application (eg. Client
4762 ID is mapped to correct SilcClientEntry entry and that is returned).
4763 Changed command_reply client operation due to this change.
4765 * Changed all ID's in commands and in command replys as ID Payloads.
4766 Change affected both client and server side codes.
4768 All ID's sent in SILC network (with execption of ID's in SILC
4769 Packet header) are sent in ID Payload to support variable length
4772 * Server now notifies nick changes and notifies all clients on
4773 the channels about the new nickname (about the new Client ID,
4776 * Implemented CMODE command to change channel modes. Supports all
4777 channel modes defined by the protocol specs except ban and invite
4778 lists. (Also, private channel key mode is supported but support for
4779 setting private channel key in client is missing, thus, this mode
4780 has no effect on client side (except that server requires that the
4781 client uses private channel key and normal channel traffic does not
4784 Also, invite mode works per se, but INVITE command does not work
4785 yet correctly, so you can set channel as invite only channel but
4786 inviting clients to the channel does not work (it is yet to be
4787 thought what's the best way to do it).
4789 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4790 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4791 Implemented CUMODE command to change user's mode on the channel.
4792 Supports all modes defined by the protocol specs.
4794 * Added NAMES command reply to return users modes on the channel.
4796 * Removed unnecessary and slow ciphers from lib/silccrypt.
4798 * Set SO_KEEPALIVE option to connection sockets by default.
4800 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4802 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4803 redefined the Notify Payload into protocol specs.
4805 * Added silc_id_payload_parse_id to get ID directly from raw
4808 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4810 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4811 accept searching by Client ID as well.
4813 * Added support for LEAVE and SIGNOFF notify types in client library.
4815 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4816 to parse ID Payload from raw data.
4818 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4820 * Added flags parameter into silc_ske_assemble_security_properties
4821 function in lib/silcske/silcske.[ch].
4823 * Changed notify client operation to fit better for notify messages
4824 sent by server. The notify payload received from server is now
4825 passed to the application (after parsing it to SilcNotifyPayload).
4826 It is application's responsibility to retrieve the arguments
4827 from the payload and show the message the way it wants. The message
4828 sent by server is implementation specific.
4830 * Changed public keys to comply with the protocol specification.
4831 Old public keys are not supported anymore and are not compatible.
4833 * Removed nickname from Channel Payload as the latest draft removed
4834 it. The client must resolve the nickname from the NAMES command
4835 reply received when it joined the channel.
4837 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4839 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4841 * Fixed some errors in protocol specification drafts.
4843 * Created lib/silccore/silcnotify.c to implement Notify Payload
4844 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4845 generic payloads described by protocol specifications. The file
4846 includes implementations for ID Payload and Argument Payload.
4848 * Changed Command Payload implementation to use the new Argument
4849 Payload. Changed command_xxxx_payload to command_payload_xxxx
4850 to comply with SILC coding conventions.
4852 * Added suppport for Argument Payload handling in Notify Payload
4853 implementation as protocol requires it. Added the new support
4854 into server and client lib as well.
4856 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4858 * Added support for multiple nicknames on same channel. [n] is
4859 added locally to the nickname if there are more than one same
4860 nicknames on the channel.
4862 * Server now sends all nicknames that matched WHOIS request.
4863 Client also shows the list received from server.
4865 * Added TOPIC command to client side. User can now set and show
4866 current topic on channel.
4868 * Added MOTD command to client and server. Also, server sends the
4869 motd when client connects to the server.
4871 * Changed version strings to comply ISO 8601.
4873 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4875 * Fixed protocol error handling in client library. It should now
4876 cope even if the SKE fails for some reason.
4878 * Made new protocol specification drafts for submitting to IETF.
4880 * Implemented TOPIC command to server in silcd/command.c.
4882 * Added two new notify types into lib/silccore/silcnotify.h:
4883 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4884 notify nickname change and topic setting/change on a channel.
4886 * API change of command_reply operation in client library. The
4887 application gets now the status type received from server as well.
4889 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4891 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4893 * Cras fixed and optimized the packet handling even further and
4894 it should work now. Minor change to the prototype of function
4895 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4897 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4899 * Added new function into lib/silcutil/silcschedule.[ch]:
4900 silc_schedule_with_fd to select() a specified fd. The function
4901 returns after timeout expires or data arrives or goes. The
4902 function is used by packet routines to wait that all data is
4903 received from network.
4905 * Fixed data reading from network in lib/silccore/silcpacket.c.
4906 The code now assures that all data is read from the fd and then
4907 continues packet processing. This was a bug fix since the code
4908 used to drop some data in some circumstances.
4910 * Added new function into lib/silcclient/client.[ch]:
4911 silc_client_start_key_exchange to start key exchange after
4912 connection has been established to server. The code internally
4913 now uses this funtion but its main purpose was to provide it
4914 for applications that perform their own connecting. After
4915 application has created a connection it merely calls this
4916 function to start the key exchange between client and server.
4917 The library takes care of everything else after that.
4919 Updated also lib/silcclient/README to explain the usage of
4922 * Do not send to application information that connection has
4923 been established. Application gets notified it by connect
4926 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4928 * Applied cras's patch to add silc_schedule_one function. The
4929 function runs scheduler once and returns.
4931 * Fixed the scheduler after cras messed it up. The timeout
4932 handling works now as it's supposed to work.
4934 * Added into lib/silccore/ silcnotify.h to include notify
4935 message types support. Changed silc_server_send_notify*
4936 functions, in server.[ch], to support those new notify types.
4937 Added the support for the notify types into client library,
4938 as well. Added new notify client operation into ops.h in
4941 * Changed silc_server_packet_send_to_channel to send normal
4942 packets instead of just channel message packets. The function
4943 is now used to send the notify packets to channels. It is not
4944 used to send channel message packets anymore, as server never
4947 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4948 va_arg()s as it seems to require it nowadays. I guess, if SILC
4949 is compiled with older va_arg() the new code should work anyway.
4951 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4953 * Splitted core library. Core library (lib/silccore) includes
4954 now only SILC protocol specific core (and common) components.
4955 Created new utility library (lib/silcutil) that includes more
4956 generic purpose stuff. The stuff for util library was taken
4957 from the old core library. This was minor and easy split.
4959 * Created SILC Client Library (lib/silcclient) that includes
4960 implementation of the SILC client without user interface. This
4961 was major move from silc/ directory. The code has been changed
4962 so that it is transparent towards the user interface. The
4963 silc/ directory includes now the same user interface as before
4964 and it uses the new client library. Read lib/silcclient/README.
4965 Basicly, the client library performs everything else related
4966 to SILC except user interface handling. Also, configuration
4967 files are considered to be part of user interface and library
4968 does not handle them.
4970 This change also changed a lot of structures, function naming etc.
4971 Most important change was that SilcClientWindow object was
4972 renamed to SilcClientConnection in the client library. Created
4973 also new file lib/silcclient/ops.h. Also added new files
4974 silc/local_command.[ch] and silc/client_ops.[ch].
4976 All these changes were made to make it easier for user interface
4977 designers to create what ever user interface for the SILC client
4980 It is also expected that the server will be moved to lib
4981 directory as well and SILC Server Library will be created;
4982 sometimes in the future.
4984 * Removed Local commands from lib/silccore/silccommand.h as
4985 they are application specific and new client library does not
4986 handle any of those anymore.
4988 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4989 old client implementation in silc/.
4991 * Added support for callback functions in SILC_LOG_* macros.
4992 Application can now set its own callbacks that will be called
4993 instead of using the default functions that will always print
4994 the debug messages to stderr (or stdout). Also, debugging can
4995 now be disabled by setting silc_debug to FALSE and re-enabled by
4996 setting it to TRUE. Note, that logging will still work even
4997 if debugging is disabled.
4999 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5000 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5001 silc_log_reset_debug_callbacks.
5003 * To enable debugging in silc client one must give now -d
5004 option on command line.
5006 * Changed silc_schedule_init to automatically allocate task queues
5007 if they are not allocated before calling it.
5009 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Added GMP 3.1 into math library.
5013 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5015 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5016 a channel in SILC network. The packet is used by servers and
5017 routers to notify other routers that user has left a channel.
5018 This little feature was missing until now. Added the feature
5019 to protocol specification as well.
5021 Added functions: silc_server_send_remove_channel_user and
5022 silc_server_remove_channel_user into server.[ch].
5024 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5025 lib/silccore/silcpacket.h. However, they are not implemented
5028 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5030 * Fixed joining to a channel and sending channel messages
5031 between server and router. The channel message sending should
5032 now work inside a cell.
5034 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5036 * Fixed the private message sending between server and router.
5037 The private message sending should now work inside a cell.
5039 * Added silc_server_replace_id into server.[ch] to replace
5040 existing ID in the SILC network.
5042 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5043 and silc_idlist_replace_server_id into idlist.[ch] in server.
5045 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Fixed the server to server connections. Server can again now
5048 connect to router. Router to router connections probably does
5051 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5053 * Added dynamic protocol registering support. Now protocols can
5054 registered and unregistered on the fly. Patch by cras.
5056 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5058 * Added lib/contrib directory to hold routines that some platforms
5059 don't have but are needed by SILC.
5061 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5062 into lin/contrib to provide getopt() and getopt_long() for
5063 those who don't have it.
5065 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5067 * Added AWAY command to client. When away message is set and
5068 client receives a private message packet the client automatically
5069 replies to the sender with the away message.
5071 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5072 bug seemed to be the cause of recent problems when compiling
5075 * Added version detection support to SKE protocol specification
5076 and added the new changes to the SKE implementation as well.
5077 There were other minor changes in the SKE protocol as well.
5079 Many changes in lib/silcske/silcske.[ch] and in
5080 lib/silcske/payload.[ch].
5082 * Added ^U functionality, clear input line. Patch from cras.
5084 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5086 * Mainly small bugfixes on core library. Fixed some debugging
5087 logging and buffer overflow in silclog.c.
5089 * Updated config.sub and config.guess on the distribution tree.
5091 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5093 * Added command lagging support in server. Client may execute
5094 commands now only once in two seconds.
5096 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5098 * Optimized packet reception. MAC computation and checking is now
5099 also more optimized. A lot previously duplicated code is now
5100 used as generic by both client and server.
5102 * Fixed key pair generation in clientutil.c
5104 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5106 * Added into lib/silccore/silcbufutil.[ch] new function;
5107 silc_buffer_realloc.
5109 * Moved generic packet sending/encryption functions to
5110 lib/silccore/silcpacket.[ch] from client and server. Some
5111 rewriting of the functions.
5113 * Moved all generic packet reception/decryption functions to
5114 lib/silccore/silcpacket.[ch] from client and server. The
5115 packet processing is now much cleaner in both client and server.
5116 These were major changes in both client and server.
5118 * Created many common functions in server to do packet sending.
5119 Previously code were duplicated a lot, this has been removed
5122 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5124 * Rewrote major parts of the ID cache system. Don't know
5125 whether it is better now or not but at least the API is more
5128 * Major rewrite on ID cache stuff on client because of the ID
5129 cache API changes. Added idlist.c to client.
5131 * Also major rewrite on ID cache stuff on server as well.
5132 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5133 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5134 in hand, instead they are all put into the ID cache system now.
5135 All server_idlist_* routines uses ID cache now instead of
5136 traversing its own lists (those lists does not exist anymore).
5137 SilcIDList though still exists. Also, SilcXXXEntry's are
5140 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5142 * Finally made the SKE implementation compliant to the protocol
5143 specification. All mp integers are now binary encoded as
5144 opposed being HEX encoded.
5146 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5149 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5150 functions: silc_[encode/decode]_pem. Also added function
5151 silc_encode_pem_file to PEM encode with newlines ('\n') for
5154 * SILC public keys are now encoded either PEM or binary. Same
5155 option is for private keys as well. By default private keys
5156 are binary encoded and public keys PEM encoded. Silly HEX
5157 encoding were removed.
5159 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5160 function to create fingerprints.
5162 * Fixed a bug in SHA1; does not change the original data anymore.
5164 * Partly implemented INFO command on client and server side.
5165 Fixed CLEAR command. Changes to SERVER command; show current
5166 server(s) when giving command without arguments. Added
5167 VERSION command to client.
5169 * Added check to server that unregistered connections cannot
5170 execute commands (unless it is specificly allowed).
5172 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5174 * Fixed screen refresh.
5176 * Fixed channel joining bug from client. On some circumstances
5177 client tried to join to a channel it had already joined.
5179 * Added public key verification process into client's protocol.c.
5180 The client now verifies the public key from user and saves
5181 it into ~./silc/serverkeys/ directory.
5183 Added into: clientutil.[ch]: silc_client_verify_server_key.
5185 * Changed SKE protocol's silc_ske_initiator_finish function
5186 to accept callback function that verifies the received public
5187 key. Removed old silc_ske_verify_public_key function.
5189 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5191 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5192 silc_pkcs_private_key[_data]_set.
5194 * Made the password and public authentication more cleaner in
5195 server's protocol.c.
5197 * Removed historic and obsolete protocol `channel_auth' from
5198 both client and server.
5200 * Removed wrong way of sending command status messages from
5201 server to client in server's command.c. The old way violated
5202 protocol specification.
5204 Changes to silccore/silccommand.[ch]: removed
5205 silc_command_encode_status_payload -> not needed anymore,
5206 changed silc_command_encode_payload_va to accept extra
5207 argument on variable argument list. The argument type must
5208 now be provided to the function. Also, added new function:
5209 silc_command_encode_reply_payload_va which is same as
5210 normal command_encode_payload_va except command status type
5211 is provided as extra argument.
5213 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5215 * Added ~./silc directory handling. The directory includes the
5216 public and private keys for the client.
5218 Added silc_client_check_silc_dir, silc_client_create_identifier
5219 and silc_client_load_keys.
5221 * Implemented SILC protocol compliant public key. Added public
5222 and private key saving to and loading from files.
5224 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5225 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5226 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5227 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5228 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5230 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5231 silc_pkcs_load_[public/private]_key.
5233 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5235 * Added silc_server_get_route (route.[ch]) to get connection
5236 data for the fastest route for given ID.
5238 * Implemented INVITE command on client and server. The command
5239 were re-defined in the SILC Protocol Specification and the
5240 implementation now complies with the specification.
5242 * Implemented PING command on client and server.
5244 * Implemented NAMES command on client and server. The server side
5245 supports currently only normal server not router server yet.
5246 Some changes to NAMES definition in SILC protocol specification.
5248 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5250 * Implemented LEAVE command on client and server.
5252 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5253 again. This change was made to the protocol as well. Server
5254 should not violate the protocol specification anymore.
5256 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5258 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5259 was tested. SOCKS4 was not but should work anyway.
