1 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3 * Added silc_ske_status_string to map the SKE error numbers
4 to readable strings. The affected files are
5 lib/silcske/silcske[_status].[ch].
7 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
9 * Do not show the private channels on the WHOIS channel list
10 as it is not allowed by the protocol. The affected file is
13 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
15 * Assure that the packet length digged from the actual packet
16 is something sensible in the silc_packet_decrypt_rest_special
17 in lib/silccrypt/silcpacket.c.
19 * Free and NULL the allocated pointer in silc_hmac_alloc if
20 the HMAC allocation fails. The affected file is
21 lib/silccrypt/silchmac.c.
23 * Print the selected security properties to the log files in
24 the server. Affected file silcd/protocol.c.
26 * Add SKE's reference counter even if calling the completion
27 callback manually. Otherwise it goes negative, although it
28 does not cause any problems. The affected file is
29 lib/silcske/silcske.c.
31 * Remove the client entry with short timeout after giving the
32 KILL command. Affected file lib/silcclient/command.c.
34 * Fixed to send error reply in WHOIS and IDENTIFY commands in
35 case all found clients are already disconnected (WHOWAS would
36 found them) in the server. Affected file silcd/command.c.
38 * Update the last_receive (time of last data received) to be
39 updated only when received private or channel message so that
40 the idle time showed in WHOIS makes more sense.
42 * Added boolean field `valid' in to the SilcClientEntry in the
43 client library to indicate whether the entry is valid or not.
44 This fixes the nickname change bug on channel when changing
45 the nickname to be same than the old (like nick to Nick) the
46 nickname formatter doesn't set the new nick anymore to Nick@host.
47 Affected file lib/silcclient/idlist.[ch].
49 * Now actually fixed the nickname changing on disconnection.
50 Added new function silc_change_nick to the Irssi SILC Client.
51 Affected file irssi/src/silc/core/client_ops.c,
52 irssi/src/silc/core/silc-nicklist.[ch].
54 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
56 * Check that the public key exists in the GETKEY command before
57 trying to encode it. Affected file silcd/command.c.
59 * Print some notifications on received public keys with GETKEY
60 command in the Irssi SILC Client. Affected files are
61 irssi/src/fe-common/silc/module-formats.[ch],
62 irssi/src/silc/core/client_ops.c.
64 * Use IDENTIFY command to resolve the server information in the
65 GETKEY command instead of INFO command. Affected file
66 lib/silcclient/command.c.
68 * All command reply functions in the client library now calls
69 the pending command reply callbacks even if an error has
70 occurred. The server has done this a long time and now it was
71 time to move the client library to this as well. Now all
72 errors can be delivered back to the pending command reply
73 callbacks if necessary. Affected files are
74 lib/silcclient/command[_reply].[ch].
76 * Change the nickname on disconnection back to the username
77 because in reconnect the server will enforce it to it anyway.
78 Affected file irssi/src/silc/core/silc-servers.c.
80 * Fixed a config file parsing bug in the Irssi SILC client.
81 Affected file irssi/src/silc/core/clientconfig.c.
83 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
85 * When printing the channel mode on JOIN, verify that the
86 channel key and channel's HMAC are valid. Affected file
87 irssi/src/silc/core/client_ops.c.
89 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
91 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
92 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
93 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
95 * Removed channel key rekey task deleting from the function
96 silc_server_save_channel_key. Affected file silcd/server.c.
97 Added explicit timeout task context instead that is used to
98 delete the task if we are registering a new task before the
101 * When channel key rekey occurs the client library now saves
102 the old channel key for a short period of time (10 seconds) and
103 is able to use it in case some is still sending channel
104 messages encrypted with the old key after the rekey. Affected
105 file lib/silcclient/[idlist.h|client_channel.c].
107 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
109 * Added check to the silc_server_new_id_real to not accept
110 new ID if it is the sender's own ID. Affected file is
111 silcd/packet_receive.c.
113 * Assure that we do not announce ourself or the one we've
114 sending our announcements when we're router and are announcing
115 servers to our primary router. Affected file silcd/server.c.
117 * Fixed silc_server_command_identify_check_client to assemble
118 correct WHOIS packet. It send corrupted WHOIS packet and
119 caused problem with router to router connections. Affected
120 file silcd/command.c.
122 Fixed also silc_server_command_whois_check the same way
123 as for the IDENTIFY command.
125 * Added new SilcIDListStatus to the server in the SilcIDListData
126 structure. The status now includes the current status of
127 the entry (like registered, resolved etc.). Affected file
128 silcd/idlist.[ch]. Defined a bunch of different status types
129 as well. This replaced the old boolean registered field as well.
131 Added resolve_cmd_ident field to the SilcClientEntry structure
132 too so that if the entry is for example being resolved so
133 another command may attach to the same pending command reply
134 without requiring to resolve the same entry again. This concept
135 should optimize the WHOIS and the IDENTIFY resolving under
136 heavy load by taking away unnecessary resolving for entries
137 that are being resolved already.
139 Added support for adding multiple pending commands for one
140 command idenfier. Affected file silcd/command[_reply].[ch].
142 * Fixed WHOIS and IDENTIFY save to remove the cache entry
143 before deleting the data. Otherwise the hash table will have
144 freed data in comparison functions. Affected file is
145 silcd/command_reply.c.
147 * Fixed silc_idlist_replace_client_id to add the new entry to
148 the cache with NULL nickname. Otherwise there will be invalid
149 memory as the nickname after the nickname is freed. Affected
150 file silcd/packet_receive.c.
152 * Fixed the silc_idlist_get_clients_by_hash. The entries was
153 saved into wrong slots because the previous number of entries
154 was not taken into account. Affected file silcd/idlist.c.
155 Fixed same thing in silc_idlist_get_clients_by_nickname too.
157 * If we are router and we receive JOIN notify to a channel that
158 does not have any users then notified client is marked as the
159 channel founder, as it is it. The affected file is
160 silcd/packet_receive.c
162 * Added to the extended hash table API's table_del_*ext functions
163 the destructor as argument too, so that the caller can decide
164 which destructor to use or whether to use destructor at all.
165 Affected file lib/silcutil/silchashtable.[ch].
167 * Fixed ID Cache purging. It actually deleted the entries from
168 the hash table after the data was freed. The hash table ended
169 up comparing freed memory. The affected file is
170 lib/silccore/silcidcache.c.
172 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
174 * Fixed Irssi SILC client's KILL command's HELP syntax.
176 * The USERS command now resolves the detailed user information
177 if the userinfo field is missing. Affected file is
178 lib/silcclient/command_reply.c.
180 * Do not print error in silc_file_read if the read file does
181 not exist. Just silently return NULL. Affected file is
182 lib/silcutil/silcutil.c.
184 * Fixed the silc_log_output to not wine about NULL filename
185 and to not create some bogus " " filename. Affected file is
186 lib/silcutil/silclog.c.
188 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
190 * Fixed various printing bugs on the user interface in the
191 Irssi SILC Client. Minor changes that were forgotten from
194 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
196 * Fixed the configure.in.pre and the compilation and distribution
197 environment to support the new autoconf 2.52. That version is
198 now required to compile the CVS trunk.
200 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
202 * Renamed function silc_parse_nickname to silc_parse_userfqdn
203 to generally parse user@fqdn format strings. Affected file
204 lib/silcutil/silcutil.c.
206 * Added nickname_format and nickname_force_format fields to the
207 SilcClientParams structure. The first one defines the format
208 for the nicknames that the library will enforce if the receives
209 multiple same nicknames. The second one is boolean value and
210 can be used to force the library to always enforce the format
211 to the nicknames regardles whether there are multiple nicknames
212 or not. This configurable formatting was employed to flexibly
213 support accessing multiple nicknames from the user interface.
214 The userinterface can now set the nicknames to what ever format
215 they prefer. Affected file lib/silcclient/silcapi.h.
217 Added function silc_client_nickname_format to the file
218 lib/silcclient/idlist.c. It performs the nickname formatting.
220 Added new field `hostname´ to the SilcClientEntry context.
221 It holds the hostname of the client. Affected file is
222 lib/silcclient/idlist.h.
224 * Irssi SILC Client sets the nicknames in nick@hostn format.
225 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
226 irssi/src/silc/core/silc-core.c.
228 The WHOIS printing now also shows both the real nickname and
229 the formatted nickname so that user knows how to access the
230 user if there are multiple same nicknames cached. Affected
231 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
232 printing formatting too to take the hostname now as a separate
233 argument. The Affected file is
234 irssi/src/fe-common/silc/modules-formats.[ch].
236 * Changed the silc_client_get_clients_local to accept the formatted
237 nickname as argument. It accepts the real nickname too but the
238 formatted nickname can be used to find the true entry from
239 multiple entries. Affected file lib/silcclient/silcapi.h and
240 lib/silcclient/idlist.c.
242 * Added nickname_format_parse field to the SilcClientParams.
243 It is a callback function provided by the application to parse
244 the nickname out of the formatted nickname string. The library
245 calls it to get the nickname from the formatted string. Since
246 the application generally knows better the format of the nickname
247 string it parses it instead of the library, even though library
248 encodes the formatted string. If the callback function is not
249 provided then the library will use the string as is. The
250 affected file is lib/silcclient/silcapi.h.
252 * All the nickname strings passed to the client library in
253 commands are now expected to be formatted nickname strings.
254 If the command does not support the formatted nickname string
255 it will assume that the sent string is the actual nickname.
256 Affected file lib/silcclient/command.c.
258 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
260 * Added public key authentication support to OPER and SILCOPER
261 commands in the client library. Affected file is
262 lib/silcclient/command.c.
264 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
266 * Changed the get_auth_methdod client operation to be asynchronous.
267 It can be async if the application resolves the authentication
268 method from the server during the negotiation. Added new
269 SilcGetAuthMeth completion callback that the application will
270 call after resolving the authentication method.
272 Added function silc_client_request_authentication_method that
273 the application can use to resolve the authentication method
274 from the server. Added also SilcConnectionAuthRequest callback
275 that the library will call after the server has replied. The
276 application can call this function if it does not know the
277 current authentication method.
279 Affected files are lib/silcclient/client.c and
280 lib/silcclient/silcapi.h.
282 * The Irssi SILC client now automatically resolves the authentication
283 method incase any configuration information is not present (and
284 currently there never is). The affected file is
285 irssi/src/silc/core/client_ops.c.
287 * Fixed public key authentication from the client library.
288 Affected file lib/silcclient/protocol.c. Changed also the
289 protocol specification about the public key authentication in
290 the connection authentication protocol. The actual data to be
291 signed is now computed with a hash function before signing.
293 * Fixed the public key authentication from the server as well.
294 Affected file silcd/protocol.c.
296 * Removed the mlock()'s from the memory allocation routines.
297 Affected file lib/silcutil/silcmemory.c. The ./configure does
298 not check anymore for the mlock(). Affected file is
301 * Fixed USERS command in server to allow the execution of the
302 command for private and secret channels if the client sending
303 the command is on the channel. Affected file silcd/command.c.
305 * Fixed silc_client_get_clients_local to return the clients
306 count correctly. It could return wrong value. Affected file
307 lib/silcclient/idlist.c.
309 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
311 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
312 types. The assembler optimizations seemed not to like 64-bit
313 data types. The assmebler optimizations thus are now enabled
314 also for BSD systems as opposed to only enable them for Linux.
316 * Do not check for threads at all on BSD systems. Affected
317 file configure.in.pre.
319 * Removed -n and -h options from the Irssi SILC Client since
320 they are not used in silc.
322 * Fixed the prime generation to assure that the first digit
323 of the generated random number is not zero since our conversion
324 routines does not like number strings that starts with zero
325 digit. If zero digit is seen the random number is regenerated.
326 This caused some corrupted RSA keys when the zero first digit
327 was met. Affected file lib/silcmath/silcprimegen.c.
329 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
331 * Fixed WIN32 configuration in the ./configure script.
332 Fixed to include xti.h on environments that has it.
333 Patches by Carsten Ilchmann and andrew.
335 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
337 * Changed the silc_id_create_client_id to be collision
338 resistant. It is now assured that there cannot be created
339 two same client ID's. I suspect that some weird bugs in
340 the server were actually caused by duplicate Client IDs.
341 Affected file silcd/serverid.[ch]. A router receiving
342 new ID now also assures and informs the sending server
343 if the ID caused collision.
345 * Changed the silc_id_create_channel_id to also assure that
346 there are no collisions.
348 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
350 * Statement about ignoring the Mutual Authentication flag when
351 performing rekey with PFS was a bit misleading. It is ignored
352 if it was set in the initial negotiation, it cannot be even
353 set in the rekey. Fixed in the ke-auth draft. Started the
354 new versions of the protocol drafts in the doc/.
356 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
358 * Fixed a bug in silc_client_command_identify_save when saving
359 new channel information. The channel name was no duplicated
360 and caused crash on exit. Affected file is
361 lib/silcclient/command_reply.c.
363 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
365 * Fixed the getkey command handling in the server. Send just
366 empty OK reply to the sender if the key could not be fetched
367 (but everything else was ok, like the key just was not available).
368 Changed the public key parameter to optional in the protocol
369 specs so that empty OK reply can be sent. Affected file
372 Added a message to Irssi SILC client to tell to user if the
373 server did not return a public key.
375 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
377 * Fixed a channel key regeneration bug. It registered new
378 timeout tasks exponentially until all system resources were
379 used. Affected file silcd/server.c.
381 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
383 * Added the SILC Document generator to the scripts/silcdoc.
384 It can be used to generate the Toolkit Reference Manual out
385 of the source tree. Internally it will also use the RoboDoc
386 generator now imported in util/robodoc.
388 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
390 * Added couple of return's in rekey protocol if error orccurred
391 during the protocol. The execution must be terminated.
392 Affected file silcd/protocol.c. Also, terminate the protocol
395 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
397 * The client's Client ID was created initally from the wrong
398 nickname (it could have been in format nick@host) in the
399 silc_server_new_client. Affected file silcd/packet_receive.c
401 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
403 * Added some SILC_LOG_ERROR's to various error conditions
404 if client could not be added to ID cache. Affected files
405 silcd/packet_receive.c and silcd/server.c.
407 * When client's sock->user_data is freed, NULL also the
408 client->router and client->connection pointers. Added check
409 for these pointers being NULL to various places around the
410 code. Affected file silcd/server.c.
412 * Added client->data.registered == TRUE checks to various
413 places around the code to assure that unregistered client's
414 are not handled when it is not allowed. Affected file
417 * Added `bool registered' fields to all
418 silc_idlist_[server|client]_get_* routines to indicate whether
419 the fetched client needs to be registered or not. Affected
420 file silcd/idlist.[ch].
422 * Add your own entry as registered to the ID cache in the
423 server. Affected file server.c.
425 * Fixed a bug in silc_server_new_server. The SilcServer was
426 set as the new server's context instead of SilcServerEntry.
427 This naturally caused some weird bugs.
429 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
431 * Do not delete the channel rekey task when adding it
432 for in silc_server_create_channel_key.
434 * Changed the silc_server_create_channel_key to return
435 TRUE or FALSE to indicate the success of the channel key
438 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
440 * Fixed MSVC++ project files and added missing files to
441 Makefiles under win32/.
443 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
445 * Do not add TCP_NODELAY flag if the operating system
446 does not have it defined. Affected files are
447 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
449 * Fixed buffer overflow from Irssi SILC Client. Affected
450 file irssi/src/fe-common/core/themes.c.
452 * Fixed double free in client library in the file
453 lib/silcclient/client.c when disconnecting from server.
455 * Applied double free patch from cras to Irssi SILC client.
456 Affected files irssi/src/core/[modules/expandos].c
458 * Fixed the disconnection handling to Irssi SILC Client.
459 The application must call silc_client_close_connection
460 in ops->connect client operation in case of failure of
461 the connection. Affected file is
462 irssi/src/silc/core/client_ops.c.
464 * Do not set sock->protocol to NULL in the function
465 silc_client_close_connection after executing the protocol's
466 final callback since the sock might not be valid anymore.
467 Affected file lib/silcclient/client.c.
469 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
471 * Do not enable SILC_THREADS if the linking with libpthread
472 did not happen. Affected file configure.in.pre.
474 * Added notion to protocol specification that server must
475 verify the sent authentication payload with CMODE when
476 setting the channel founder key. Implemented it to the
477 server. Affected file silcd/command.c.
479 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
481 * Added _EXTRA_DIST SILC distribution variable to the
482 distributions file. It is used to conditionally add extra
483 files or directories to the specific distribution. Affected
484 files ./prepare, Makefile.am.pre and distributions.
486 Removed the `_' from the start of the distribution names.
489 * Added README.WIN32 for instructions to compile the Toolkit
492 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
494 * Fixed a double free in disconnection in the server. Affected
495 file is silcd/server.c.
497 * Fixed the lib/silcske/groups.c to work now also with GMP
498 MP library. The string conversion did not work when using
499 specific base and the base is indicated in the string as well.
501 * Created win32/ directory which now includes MSVC++ specific
502 stuff so that toolkit (DLLs) may be compiled with MSVC++.
503 It will appear only in the toolkit distribution
505 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
507 * Changed the key material distribution function in case when
508 the hash output is too short. The data is now concatenated
509 a bit differently than it used to. Made the change to the
510 SKE protocol specification.
512 * Added better GMP detection to configure.in.pre. A patch
515 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
517 * Fixed a minor bug in SKE that might cause some problem on
518 some platforms. Affected file lib/silcske/silcske.c.
520 * Added the cookie checking for initiator in the SKE. It checks
521 that the responder returns the sent cookie unmodified. The
522 affected file is lib/silcske/silcske.c. Added new SKE
523 error type INVALID_COOKIE that can be sent during the
524 negotiation. Fixed some memory leaks as well.
526 * Added the "invalid cookie" error message to Irssi SILC client's
529 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
531 * Added `task_max' field to the SilcClientParams to indicate
532 the maximum tasks the scheduler can handle. If set to zero,
533 default values are used. Affected file lib/silcclient/silcapi.h.
535 * Fixed memory leaks in silc_client_close_connection. Affected
536 file lib/silcclient/client.c.
538 * Added silc_client_del_client_entry to client library to free
539 all memory of given client entry. Affected file is
540 lib/silcclient/idlist.[ch].
542 * Added new functions silc_client_del_channel and
543 silc_client_del_server to delete channel and server entries.
544 Affected file lib/silcclient/[silcapi.h/idlist.c].
546 * Removed silc_client_del_client_by_id from silcapi.h.
548 * Fixed the INFO command to return the server's own info
549 correctly when querying by Server ID. Affected file is
552 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
554 * Removed the non-blocking settings in WIN32 code in the
555 silc_sock_[read/write] and added SleepEx instead. Affected
556 file lib/silcutil/win32/silcwin32sockconn.c. The availability
557 of input data is now checked with FIONREAD and ioctlsocket.
559 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
561 * Call silc_schedule_task_del_by_context in the
562 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
563 Affected file lib/silccore/silcprotocol.c.
565 * Call silc_protocol_cancel for active protocols in the
566 silc_server_close_connection if the funtion
567 silc_server_free_sock_user_data has not been called.
568 Affected file silcd/server.c.
570 * Generic tasks cannot be deleted using the del_by_fd
571 task deleting function since generic tasks does not match
572 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
574 * Added a notion to SILCOPER help file that the SILCOPER works
575 only on router server, not on normal server.
577 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
579 * Added for WIN32 support for the new scheduler as well.
580 Affected file lib/silcutil/win32/silcwin32schedule.c.
582 * Fixed the SHA1 implementation to work on various platforms.
584 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
586 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
587 API. It is part of the scheduler now. Everything else is
588 as previously but some functions has changed their names.
589 Checkout the lib/silcutil/silcschedule.h for the interface.
590 Updated all applications to use the new interface. Affected
591 files are lib/silcutil/silcschedule.[ch].
593 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
595 * Found a bug in the SKE implementation. The HASH value,
596 specified by the protocol, was not computed correctly. The
597 public key of the responder was not added to the computation
598 even though it is mandatory. Affected file lib/silcske/silcske.c.
599 This unfortunately causes incompatibilities with older
602 * Added WIN32 specific network init and uninit functions:
603 silc_net_win32_init and silc_net_win32_uninit to init and uninit
604 the Winsock2. Affected file lib/silcutil/silcnet.h and
605 lib/silcutil/win32/silcwin32net.c.
607 * Set the socket always to nonblocking mode on WIN32 after
608 reading data or writing data. Affected file is
609 lib/silcutil/win32/silcwin32sockconn.c.
611 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
613 * Fixed various compilation problems under WIN32. Affected
614 files lib/silcutil/win32/silcwin32thread.c and
615 lib/silcutil/win32/silcwin32schedule.c.
617 * Removed all _internal.h #includes from public header
618 files. Internal headers must never be included from
621 Removed also the lib/silcske/payload_internal.h file.
623 * All include files that may be needed (public and some others
624 included by the public headers) by application developers are
625 now copied to the ./includes directory. It does not copy any
626 internal headers. Affected file Makefile.defines.pre and all
627 Makefile.am's under lib/ and subdirs.
629 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
631 * Do not change the ~/.silc directory's permissions automatically.
632 Affected file irssi/src/silc/core/clientutil.c.
634 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
636 * Do not cancel the protocol in silc_server_close_connection
637 it might cause recursion. Now cancelled in the function
638 silc_server_free_sock_user_data. Affected file silcd/server.c.
640 * Fixed the silc_server_remove_clients_by_server to regenerate
641 the channel keys correctly finally. Added also new function
642 silc_server_remove_clients_channels to actually do it.
643 Affected file silcd/server.c.
645 * Fixed the silc_server_new_channel to not crash by giving
646 wrong router to the new channel. Affected file is
647 silcd/packet_receive.c.
649 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
651 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
652 which is given as argument to the silc_client_alloc now.
653 It can be used to configure the client and set various parameters
654 that affect the function of the client.
656 * The USERS command in server did not check whether the channel
657 is private or secret. Affected file silcd/command.c.
659 * Added new argument to the USERS command in protocol specification.
660 The USERS command now can take the channel name as argument
661 as well. Added support for this in client and server and
662 updated the protocol specs.
664 * Completed the GETKEY command in client. It can be now used
665 to fetch also servers public key not only some clients.
666 Affected files lib/silcclient/command[_reply].c.
668 * Added silc_client_get_server to return server entry by the
669 server name. Affected files lib/silcclient/silcapi.h and
672 * Redefined the IDENTIFY command in protocol specification to be
673 more generic. It now can be used to query information about
674 any entity in the SILC Network, including clients, servers and
675 channels. The query may be based either the entity's name
676 or the ID. Added support for this in both client and server.
678 Affected files silcd/command.c and lib/silcclient/command.c
681 * Optimized the WHOIS and WHOWAS commands in the server. Removed
682 the _from_client and _from_server functions. Affected file
685 * Added silc_client_get_channel_by_id_resolve to the file
686 lib/silcclient/silcapi.h to resolve channel information by
687 its ID. Added also silc_client_get_channel_by_id that
688 does not resolve it from the server.
690 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
692 * Added SilcServerEntry context into the client library
693 to represent one server. The INFO command now allocates
694 these to save the resolved server info. For now on the
695 client library will also keep information about servers,
696 connected and resolved with INFO.
698 The INFO command now allocates the SilcServerEntry context
699 and saves the server info there. The COMMAND_REPLY in
700 the INFO now returns the parameters to application in
701 same order as defined in the protocol specification.
703 The entries are cached in the client->server_cache.
705 * The INFO command is now issued after received the Client ID
706 from the server. Affected file lib/silcclient/client.c.
708 * The CMODE_CHANGE notify may now return also an SilcServerEntry
709 to the application as the mode changer might be server.
710 It is guaranteed that NULL is not returned anymore to the
711 application. Affected file lib/silcclient/client_notify.c.
713 The ID Type is now also passed to the application so that
714 it can check whether the returned entry is SilcClientEntry
717 Added new function silc_client_get_server_by_id to return
718 the server entry by ID. Affected files are the
719 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
721 * Do not create the channel in the Irssi SILC Client when issuing
722 the JOIN command but when received the sucessful JOIN command
723 reply. Otherwise the channel might get created even though we
724 could not join it. The Affected file is
725 irssi/src/silc/core/[silc-channels.c/client_ops.c].
727 * Fixed a channel joining bug in router. The router must also
728 check the channel modes, invite and ban lists etc. when serving
729 the JOIN command sent by normal server. Affected file is
730 silcd/command.c. The router now resolves the client's
731 information from the server who sent the JOIN command if it
732 does not know it, and processes the JOIN command only after
735 * Changed the SilcCommandCb to take new argument; void *context2.
736 Affected file lib/silccore/silccommand.h
738 The second argument in the command callbacks in the server now
739 includes the SilcServerCommandReplyContext if the command was
740 called as pending command callback from the command reply.
741 Otherwise it is NULL. When called as pending the status of the
742 command reply will be checked and if it was erronous the
743 error will be sent to the original sender of the command.
744 This way the client always receives the error messages even
745 though the server was actually the one who received the error
746 when it resent the command to router, for example. Affected
747 files silcd/command[_reply].[ch].
749 * Fixed sending WHOWAS command's error message to client if
750 the requested client could not be found. It was missing.
753 * Changed the CMODE and CUMODE commands reply arguments in the
754 protocol specification. The Channel ID is now sent in both
755 of the commands to identify the channel. Implemented this
756 new feature to the client and server. Affected files
757 lib/silcclient/command_reply.c and silcd/command.c.
759 * Made better checks for invite and ban lists in the JOIN
760 command in server. Affected file silcd/command.c.
762 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
764 * The server now performs the incoming host IP/DNS lookup
765 using the silc_socket_host_lookup and thus does not block
766 the server anymore. Affected file silcd/server.c.
768 * Completed the multi-thread support for SILC Scheduler in
769 the lib/silcutil/silcschedule.c.
771 * Fixed the configure.in.pre to detect the pthread correctly
774 * Fixed a deadlock in silc_task_queue_wakeup in the file
775 lib/silcutil/silctask.c.
777 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
779 * Added new function silc_schedule_wakeup that is used in
780 multi-threaded environment to wakeup the main thread's
781 schduler. It needs to be used when a thread adds a new task
782 or removes a task from task queues. After waking up, the
783 scheduler will detect the task queue changes. If threads
784 support is not compiled in this function has no effect.
785 Implemented the wakeup mechanism to both Unix and WIN32
786 systems. Affected files are lib/silcutil/silcschedule.[ch],
787 lib/silcutil/unix/silcunixschedule.c and the
788 lib/silcutil/win32/silcwin32schedule.c.
790 * Added new function silc_task_queue_wakeup to wakeup the
791 scheduler by the specified task queue. Affected file
792 lib/silcutil/silctask.[ch].
794 * The silc_socket_host_lookup_start now wakes up the scheduler
795 after adding the timeout task. Affected file is
796 lib/silcutil/silcsockconn.c.
798 * The silc_socket_host_lookup is synchronous now if the threads
799 support is not compiled in. However, the callback is still
800 called asyncronously through the scheduler, anyway. Affected
801 file lib/silcutil/silcsockconn.c.
803 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
805 * Added new function silc_socket_host_lookup to perform
806 asynchronous IP and FQDN lookups for the socket connection.
807 Affected files lib/silcutil/silcsockconn.[ch].
809 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
811 * Added SILC_MUTEX_DEFINE to define the mutex on environments
812 that may or may not compile the mutex support in.
814 Changed the silc_mutex_alloc interface. It allocates the
815 mutex now to the sent pointer and returns TRUE or FALSE.
817 Affected file lib/silcutil/silcmutex.h.
819 * Wrote the SILC Task Queue interface to support multi-threads.
820 Affected file lib/silcutil/silctask.[ch].
822 * Wrote the SILC Scheduler to support multi-threads. Affected
823 file lib/silcutil/silcschedule.c.
825 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
827 * Implemented the SILC Mutex API and SILC Thread API for WIN32
828 in lib/silcutil/win32/.
830 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
832 * Defined SILC Mutex API and SILC Thread API and implemented
833 them for Unix. Affected files are
834 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
835 lib/silcutil/unix/silcunixmutex.c and
836 lib/silcutil/unix/silcunixthread.c.
838 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
840 * Fixed the silc_server_remove_clients_by_server's channel
841 key re-generation. The hash table handling was incorrect
842 and would not work with many channels. Affected file is
845 * Fixed some memory leaks around the server code.
847 * Rewrote the silc_server_get_users_on_channel to support IPv6
848 based Client ID's. Affected file silcd/server.c.
850 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
851 specification. However, a separate document must be written
852 to define the detailed signing procedure and the payload
853 associated with the flag. Defined the flag to the
854 lib/silccore/silcchannel.h as well.
856 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
858 * Changed the dynamic tables to static size tables in the
859 lib/silccrypt/silchmac.c.
861 * Removed GCC dependencies from the code. A patch by cras.
863 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
865 * Do not show the error "Error receiving packet bla bla"
866 in server if it really was not an error (-2 means that reading
867 is pending). Affected file silcd/server.c.
869 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
871 * Fixed a possible crash in silc_server_remove_clients_by_server
872 in silcd/server.c. Fixed there also some memory leaks.
874 * Fixed the silc_idlist_replace_client_id. It could replace
875 wrong key in the hash table. Affected file silcd/idlist.c.
877 * Do not check whether there are global users on the channel
878 if the channel->global_users is FALSE. Affected functions
879 silc_server_remove_from_one_channel and
880 silc_server_remove_from_channels in silcd/server.c. Also,
881 do not check if the removed client is local as we can be
882 sure that global client was not removed from the channel
883 and checking for global users is not needed.
885 * The silc_server_remove_clients_by_server now re-generates
886 the channel keys correctly for those channels that had
887 clients removed from them. Affected file silcd/server.c.
889 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
891 * Found the reason of random crashes in the server. We weren't
892 ignoring the SIGPIPE signal (which can be sent in write())
893 and it crashed the server. Affected file silcd/silcd.c.
895 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
897 * Assure that sock->user_data is not NULL in the function
898 silc_server_packet_send in silcd/packet_send.c.
900 * Disconnect the remote connection if it could not be added
901 to any ID lists in the server. The affected file is
904 * Check in silc_server_packet_send[_real/dest] that the
905 socket is not disconnecting and ignore the data if it is.
906 Affected file silcd/packet_send.c.
908 * Define inline to __inline on native WIN32 compilation.
909 Affected file includes/silcwin32.h.
911 * Added some explicit type casts for inline code since MSVC
912 require them. Affected files lib/silcutil/silcbuffer.h,
913 lib/trq/silcdlist.h and lib/trq/silclist.h.
915 * Print warning in log files from now on if the packet
916 decryption fails. Affected file silcd/server.c.
918 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
920 * Changed the `say' client operation's interface to accept
921 new `type' argument to indicate the type of the message sent
922 by the library. The application may filter the library's
923 messages according the type. The affected file is the
924 lib/silcclient/silcapi.h.
926 * Added two new functions to lib/silcclient/silcapi.h:
927 silc_client_del_client and silc_client_del_client_by_id.
928 Affected file lib/silcclient/idlist.c.
930 * Moved the clientincludes.h from includes/ to silc/ and
931 serverincludes.h from includes/ to silcd/.
933 * The modes for the CMODE and CUMODE are now passed as
934 uint32 for application with COMMAND_REPLY. The affected
935 file is lib/silcclient/command_reply.c.
937 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
939 * /WHOIS without arguments shows client's own information.
940 Affected file lib/silcclient/command.c.
942 * Changed PING to not accept any arguments. The specs
943 says that client can ping only the connected server so
944 requiring an argument is not needed. Affected file is
945 lib/silcclient/command.c.
947 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
949 * Fixed a fatal bug in private message sending and reception
950 encryption and decryption when using private message keys.
951 The implementation was incorrect and did not follow the
952 specification. It causd that some of the message were
953 lost since it did not use the sending and receiving keys
954 as the protocol suggests. This has been fixed and will cause
955 incompatibilities with older clients when sending private
956 message encrypted with private message keys. Affected files
957 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
958 and various other in Irssi SILC Client.
960 Added `responder' boolean argument to the functions
961 silc_client_add_private_message_key[_ske] to indicate when
962 the key is added as responder or initiator of the key
965 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
967 * Removed the silc_ske_check_version function and created
968 a SilcSKECheckVersion callback. Added also a function
969 silc_ske_set_callbacks that is now used to set all SKE
970 callbacks. The callback functions are not given to
971 the SKE functions anymore, but this function is used to
974 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
976 * Added `silc_version' argument to the silc_client_alloc
977 to define the version of the application for the library.
978 The library will use the version string to compare it
979 against the remote host's (usually a server) version
980 string. Affected file lib/silcclient/silcapi.h
982 * Added the KE protocol context to Key Agreement context
983 in client library so that we can abort the SKE if it
984 is in process when we get timeout. Affected file is
985 lib/silcclient/client_keyagr.c.
987 * Do not resolve the client ID forever if it returns in the
988 first time that such client does not exist. This was done
989 for example with private message. Affected file is
990 lib/silcclient/client_prvmsg.c.
992 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
994 * Do not add regex.h for WIN32. The affected file
995 includes/silcincludes.h.
997 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
998 not work yet 100%. It generates the DLL's automatically
999 when compiling with --with-win32 under cygwin.
1001 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1003 * lib/contrib/regex.c is not compiled on WIN32.
1005 * Added silc_net_get_socket_opt function to the
1006 lib/silcutil/silcnet.h.
1008 * Added includes/silcwin32.h for WIN32 specific includes
1011 * Do not use ptime structure or any of the posix process
1012 functions on WIN32 in lib/silccrypt/silrng.c.
1014 * Added silc_gettimeofday to provide generic function
1015 for struct timeval on all platforms. Added the function
1016 to lib/silcutil/silcutil.h.
1018 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1020 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1021 library as they clearly belong there. As a plus side we
1022 can make the actual socket connection routines platform
1025 Added also new generic function silc_socket_read and
1026 silc_socket_write (that used to be silc_packet_[read/write].
1027 The implementation of these are platform specific.
1029 * Added WIN32 specific routines of silc_socket_[read/write]
1030 to lib/silcutil/win32/silcwin32sockconn.c.
1032 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1034 * Added preliminary support for native WIN32 compilation under
1035 cygwin (using the -mno-cygwin option for GCC) to the
1036 ./configure.in.pre. The --with-win32 now prepares the
1037 compilation for native WIN32.
1039 * Rewrote the SILC Scheduler interface in the file
1040 lib/silcutil/silcschedule.h. The scheduler is now context
1041 based and does not have anymore any global static scheduler.
1042 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1043 and created lib/silcutil/win32 directory for WIN32 based
1046 * Added Unix specific network routines to the
1047 lib/silcutil/unix/silcunixnet.c and the old
1048 lib/silcutil/silcnet.c includes now only generic routines.
1050 Added WIN32 specific network routines to the
1051 lib/silcutil/win32/silcwin32net.c.
1053 * Added Unix specific utility functions from the
1054 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1056 * Added WIN32 SILC Scheduler to the file
1057 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1060 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1062 * Do not handle JOIN notify in the server if the target client
1063 is not registered (idata->registered == FALSE). The affected
1064 file is silcd/packet_receive.c.
1066 * Update the nickrec->founder in event_cumode in the Irssi SILC
1067 client. Affected file irssi/src/silc/core/silc-channels.c.
1069 * Fixed the CUMODE_CHANGE notify handling in the server when
1070 server and router are announcing their clients on channels.
1071 Now the mode changes are saved and notified correctly. The
1072 affected file is /silcd/packet_receive.c.
1074 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1075 They really did not replace the cache entry in the ID Cache.
1076 Now they do that. Affected file silcd/idlist.c.
1078 * Fixed the KICK notify handling in the Irssi SILC client to
1079 update the channel records so that the kicked client does not
1080 appear to be on the channel. The affected file is
1081 irssi/src/silc/core/silc-channels.c.
1083 * Always update the conn->current_channel when executing command
1084 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1086 * Fixed the KILL notify handling in Irssi SILC client to remove
1087 the killed client on all channels.
1089 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1091 * Fixed the silc_parse_command_line to remove extra spaces
1092 from the start and end of the arguments. Affected file is
1093 lib/silcutil/silcutil.c.
1095 * Cancel and free any active protocol in the function
1096 silc_server_close_connection. Affected file silcd/server.c.
1098 * Cancel and free any active protocol in the function
1099 silc_client_close_connction. Affected file is
1100 lib/silcclient/client.c.
1102 * Do not execute the KILL command for clients that are in
1103 history (ie. they are not in the network). Affected file is
1106 * Fixed KILL notify handling, client does not crash anymore.
1107 Affected file irssi/src/silc/core/silc-channels.c.
1109 * Reduced the default packet buffer size from 2048 to 1024 in
1110 lib/silccore/silcpacket.c.
1112 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1113 counter to the SKE context that is incresed when the SKE library
1114 performs async operation outside the library. If the outside
1115 process frees the SKE context and FREED status will be set
1116 and the library will detect after the sync operation that the
1117 libary is freed. The affected files are
1118 lib/silcske/silcske[_status].[ch].
1120 * Resolve the client entry information in the function
1121 silc_client_channel_message to assure that NULL pointer is not
1122 passed as client entry to the application. */
1124 * Fixed the task timeout calculation to assure that there is
1125 never negative timeouts. The affected file is
1126 lib/silcutil/silcschedule.c.
1128 * Fixed the channel user mode notification sending in server.
1129 It was sent point-to-point to the router (or to server by router)
1130 but it needs to be destined to a channel. The routines now
1131 supports sending the channel user mode notifys to the channels
1132 when announcing clients and channels. Affected files are
1133 silcd/server.c and silcd/packet_receive.c.
1135 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1136 It did not actually replace the old channel entry in the cache.
1137 Affected file lib/silcclient/client_notify.c.
1139 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1141 * Fixed a possible crash in silc_packet_send_prepare. It now
1142 assures always that there is enough space in the buffer and
1143 at the tail area of the buffer (for MAC).
1145 Fixed the inbound buffer reallocation in silc_packet_read.
1146 It was old code and did not handle the reallocation correctly.
1149 The affected file is lib/silccore/silcpacket.c.
1151 * Fixed buffer overflow in silc_parse_nickname in the file
1152 lib/silcutil/silcutil.c.
1154 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1156 * make install generates new server keys only if there is not
1159 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1161 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1162 Added check that if the NOREPLY is set then we will not send
1163 the away message. This avoids infinite loop of away messages
1164 if both clients are away. The affected file is
1165 lib/silcclient/client_prvmsg.c.
1167 * Fixed client crash if /NICK was given without arguments.
1168 Affected file lib/silcclient/command.c.
1170 * Server does not send the invite list in INVITE command back
1171 to the client if the list was not altered. Added this notion
1172 to the protocol spec as well. Affected file silcd/command.c.
1174 Fixed possible crash in INVITE command by checking the
1175 value of silc_server_get_client_route command.
1177 * Fixed the INVITE notify type handling. The arguments are now
1178 taken in correct order and client does not crash. The affected
1179 file is irssi/src/silc/core/silc-channels.c.
1181 Removed the "Inviting xxx to channel" message from the
1182 client library away and let the application handle it.
1183 Affected file lib/silcclient/command.c. Added that message
1184 to Irssi SILC client's message formats.
1186 * Fixed CMODE command crash in client. It now checks the
1187 amount of arguments correctly and does not crash. The affected
1188 file is lib/silcclient/command.c.
1190 * Do not create new channel automatically in silc_channels_join
1191 but check whether the channel by that name already exists.
1192 Affected file irssi/silc/core/silc-channels.c.
1194 * Do not send the SERVER_SIGNOFF to router if the disconnected
1195 entity was the router. Affected file silcd/server.c.
1197 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1198 SILC client as it was missing from there.
1200 Added the handling of the KICK notify to the Irssi SILC client
1201 as it was missing. Added "you have been kicked" message to
1202 Irssi SILC client's message modules formats.
1204 Added the handing of the KILL notify to the Irssi SILC client
1205 as it was missing. Added the kill message module formats
1208 The affected file is irssi/src/silc/core/silc-channels.c.
1210 * The router did not save the channel mode the server announced.
1211 Affected file silcd/packet_receive.c.
1213 * Fixed a possible crash in INFO command in server. If the
1214 server did not provide the server info it crashed. Affected
1215 file silcd/command.c.
1217 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1219 * Fixed the GETKEY command in the server to check also the
1220 global list. Otherwise the GETKEY would not work correctly
1221 in normal SILC server. Affected file silcd/command.c.
1223 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1225 * Fixed GETKEY crash, it crashed if the command did not succseed.
1227 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1229 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1230 is now real and not just an macro interface to GMP.
1232 Removed the entire GMP from the source tree and imported new
1233 NSS MPI library instead. Reason for removing GMP is that it is
1234 extremely large and compiles extremely slow. The NSS MPI
1235 is only a few files and compiles in less than 10 seconds.
1236 The speed is also about the same as GMP. The MPI is imported
1237 to lib/silcmath/mpi.
1239 If the system has GMP installed we will still use the GMP.
1240 If it is not then the NSS MPI will be compiled.
1242 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1244 * Merged a long nickname (127 characters long) crash bugfix from
1245 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1247 * Merged a freed memory reference bugfix from Irssi CVS tree.
1248 Affected file irssi/src/core/commands.c.
1250 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1252 * Added the server's public key sving and verification to the
1253 server when performing the SKE. This was missing and the
1254 remote server's (or router's) public key was accepted without
1255 checking whether we have it previously or trust it at all.
1256 Affected file silcd/protocol.c.
1258 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1260 * Check in the silc_server_timeout_remote if protocol is active
1261 and make sure that the protocol's final callback is called so
1262 that all memory if freed. Affected file silcd/server.c.
1264 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1266 * silc_server_whois_send_reply crashed the server if the nickname
1267 was 127 characters long. Affected file silcd/command.c.
1269 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1271 * Added sanity check to the silc_server_new_client. If the hostname
1272 is provided inside username then check that the provided hostname
1273 really is the same as the resolved one. If the hostname was not
1274 resolved then check it from the public key. Affected file is
1275 silcd/packet_receive.c.
1277 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1278 if the server disconnected us and the connection is not valid
1279 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1281 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1282 the library to the lib/silcutil/silcutil.[ch].
1284 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1286 * Close log file after open. Affected file
1287 lib/silcutil/silclog.c.
1289 * Check whether sock == NULL in silc_client_send_packet and return
1290 if it is. Affected file lib/silcclient/silcclient.c.
1292 * Check rec->entry == NULL in the Irssi SILC Client before
1293 sending the channel message. Affecte file is
1294 irssi/src/silc/core/silc-servers.c.
1296 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1298 * Merged a splitted window bugfix from Irssi CVS tree. The
1299 affected file is irssi/src/fe-text/textbuffer-view.c.
1301 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1302 It did not print nickname.
1304 * Improved the distributions system a bit.
1306 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1308 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1309 irssi/src/fe-text/gui-window.c.
1311 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1312 to in-active server. The affected file is
1313 irssi/src/silc/core/client_ops.c.
1315 * Resolve the client in USERS command reply if the entry does
1316 not have username resolved. The affected file is
1317 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1318 command to WHOIS command to really resolve stuff. The USERS
1319 is not used any more in any critical section so WHOIS can
1320 be used even though it might be slower than IDENTIFY.
1322 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1325 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1327 * Changed the protocol API a bit more consistent in the
1328 lib/silccore/silcprotocol.[ch].
1330 * Changed the following headers to ROBODoc format:
1332 lib/silccore/silcpayload.h
1333 lib/silccore/silcprotocol.h
1334 lib/silccore/silcsockconn.h
1336 All core library headers are now formatted.
1338 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1340 * Fixed a bug in Irssi SILC client; do not show that you are
1341 server/router operator if you really are not. Affected file is
1342 irssi/src/silc/core/client_ops.c.
1344 * Renamed silc_command_free_payload to silc_command_payload_free.
1345 Affected file lib/silccore/silccommand.h
1347 * Added silcmath.h to include the prototoypes of various routines
1348 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1351 * Changed the following headers to ROBODoc format:
1353 lib/silccore/silcchannel.h
1354 lib/silccore/silccommand.h
1355 lib/silccore/silcid.h
1356 lib/silccore/silcidcache.h
1357 lib/silccore/silcmode.h
1358 lib/silccore/silcnotify.h
1359 lib/silccore/silcpacket.h
1360 lib/silcmath/silcmath.h
1362 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1364 * Added checking to the server code not to start the server if
1365 ciphers and stuff are not configured properly. Affected files
1366 silcd/serverconfig.[h] and silcd/server.c.
1368 * Changed the layout of the header files of the public interfaces
1369 in the SILC libraries. The new layout supports ROBODoc
1370 documentation tool (and some others) so that it is easy to create
1371 a library reference manual. All the other headers and source
1372 code must still follow the CodingStyle document. Also source
1373 code must not include these ROBODoc stuffs, only the headers.
1374 Furthermore, all public interface headers must now be named
1375 by using `silc' prefix, example: silcapi.h, silccipher.h.
1376 Some files were renamed due to this. All the other headers
1377 must not be used as public interfaces. I will update the
1378 CodingStyle document later. Changed following headers, so far:
1380 lib/silcclient/silcapi.h
1381 lib/silccore/silcauth.h
1382 lib/silccore/silcprivate.h
1383 lib/silccrypt/silcdh.h
1385 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1389 * Removed silc_client_packet_send_flush from the client library
1390 as it is not needed. Affected file lib/silcclient/client.[ch].
1392 * Added printing of message of unresolved authentication method
1393 to the Irssi SILC client. Added it to the module formats.
1394 Removed the same message from the client library.
1396 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1398 * Added new distribution feature, DISTLABEL. Every distribution
1399 can define own preprocessor label that can be used in the
1400 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1401 file distributions, acconfig.h.pre and prepare.
1403 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1405 * Added Makefile.defines_int to include the actual definitions
1406 for Makefile.defines.in. Tested the new distribution system,
1407 created distributions and tested installation.
1409 * Added AWAY message printing to the Irssi SILC client. Added
1410 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1412 * Added SCONNECT command to call the SILC's CONNECT command.
1413 Cannot use CONNECT directly since Irssi uses that internally.
1414 Affected file irssi/src/silc/core/silc-servers.c.
1416 Added ACTION local command. It is same as ME command but takes
1417 the channel as mandatory argument.
1419 Rewrote some of the Irssi's help files to suite for SILC
1422 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1424 * Added Makefile.defines[.in] that should for now on be included
1425 in all Makefile.am file in the source tree. That file includes
1426 all common compilation definitions for SILC source tree.
1428 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1430 * Minor changes to the ./prepare script to change the package
1431 name according the distribution name to the configure.in.
1433 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1435 * Created new distribution system. Added file `distributions'
1436 that defines all the distributions that can be created out of
1437 the SILC source tree. The ./prepare script now reads that
1438 file to determine how to prepare the distributions. The
1439 first argument to the ./prepare is the name of the distribution
1440 and second is the version of the distribution. If given
1441 without arguments it creates the default (toolkit) distribution
1442 with the default version (defined in ./prepare).
1444 All Makefile.am files that are subject to the distributions
1445 are now named as Makefile.am.pre. These are ./Makefile.am
1446 and lib/Makefile.am. Others may be changed later.
1448 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * Added invite list, ban list, some key management and connection
1451 error message printing to module formats in the Irssi SILC client.
1453 * Added new silc_client_set_away_message to set the away message
1454 that is back to the person who sent private message. The
1455 affected file lib/silcclient/silcapi.h and the
1456 lib/silcclient/client_prvmsg.c.
1458 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1460 * Fixed the private message sending in the Irssi SILC client,
1461 added local command KEY to the Irssi SILC client.
1463 Added key management and key agreement message formats to the
1464 irssi/src/fe-common/silc/module-formats.[ch].
1466 Added USERS (alias WHO) printing, server/router operator
1467 indication and LIST command printing to the module formats.
1469 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1471 * Fixed channel joining notify handling, cumode notify handling
1472 from Irssi SILC client.
1474 * Added SILC specific module-formats to the Irssi SILC client so
1475 that SILC specific message hilighting, colors etc is possible.
1476 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1478 Added channel mode, channel user mode, actions, notices,
1479 whois and whowas printing to the the module-formats.c.
1481 * Fixed a bug in channel deletion in the server. The channel
1482 is not left to the cache even if the channel founder auth mode
1483 is set when there are no users anymore on the channel. Affected
1484 file silcd/server.c.
1486 * The silc_net_localhost now resolves the entire hostname including
1487 the domain name. Affected file lib/silcutil/silcnet.c.
1489 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1491 * Changed the ask_passphrase client operation to be ascynchronous.
1492 It has now a completion callback and a context that the
1493 application must call after it has got the passphrase from
1494 the user. Affected files lib/silcclient/silcapi.h,
1495 lib/silcclient/protocol.c, lib/silcclient/command.c and
1498 Added SilcAskPassphrase callback that the application calls
1499 to deliver the passphrase to the library.
1501 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1502 The public key verification and especially a certificate
1503 verification is asynchronous procedure.
1505 Added new SILC_SKE_STATUS_PENDING status to indicate the
1506 request is pending and a callback will be called to finalize
1509 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1510 indicate that remote end did not send its public key (or
1511 certificate), even though we require it. Added check for this
1512 condition in the SKE. This was a security bug, now fixed.
1514 Defined new SilcSKEVerifyCbCompletion callback that is called
1515 when the verification process is completed.
1517 The affected files lib/silcske/silcske_status.h and
1518 lib/silcske/silcske.[ch].
1520 * Changed the verify_public_key client operation to be async
1521 as well. Defined SilcVerifyPublicKey callback that is used to
1522 indicate the success of the public key verification process.
1524 Changed the server and client to use the new async client
1527 * Changed the Irssi SILC client's internal scheduler to be called
1528 twice as many times as it used to be. As a result the client
1529 should be a bit faster now. Affected file is
1530 irssi/src/silc/core/silc-core.c.
1532 * Added support to Irssi SILC client of asynchronous public key
1533 verification and passphrase inquiry. Affected file is
1534 irssi/src/silc/core/silc-core.c.
1536 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1538 * Do not say "You have left channel %s" in client library.
1539 Moved it to the application. Affected files are
1540 lib/silcclient/command.c and silc/client_ops.c.
1542 * Fixed silc_client_get_clients. Command context was not
1543 duplicated and was freed memory in the callback. Affected
1544 file lib/silcclient/idlist.c.
1546 * Do not say "you are now talking..." on JOIN command in the
1547 client library. The appliation must handle it.
1549 * Do not say ".. changed topic to" in command reply in the
1550 client libary. The application must handle it.
1552 * Fixed TOPIC command sending in the client library.
1554 * Fixed a memory leak in silc_client_command_free in the file
1555 lib/silcclient/command.c.
1557 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1559 * Imported a modified version of Irssi client to the source tree.
1560 The Irssi will be used to create a new client called
1561 Irssi SILC. Imported to irssi/.
1563 Added silc_core_init_finish function to the Irssi. Affected
1564 file irssi/configure.in.
1566 A lot changes in the Makefile.ams around the irssi tree.
1568 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1570 * Do not rehash if the new size is same as the old size of the
1571 hash table, in the silc_hash_table_rehash*. The affected file
1572 lib/silcutil/silchashtable.c.
1574 * Replaced hash_table_del_by_context calls from the server
1575 (when channel->user_list and client->channels) to the
1576 hash_table_del as it is sufficient and faster.
1578 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1580 * Added silc_hash_table_list, silc_hash_table_get and the
1581 SilcHashTableList structure to provide an alternative way to
1582 traverse the hash table. The affected files are
1583 lib/silcutil/silchashtable.[ch].
1585 * Changed the server's idlist routines to use the hash table
1586 routines to optimize the code.
1588 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1590 * Replaced the client entry's `channel' list and channel entry's
1591 `user_list' list to hash tables for optimized lookup. Changed
1592 the code to use the hash table interface around the code.
1593 Affected file lib/silcd/idlist.[ch].
1595 * Added `auto_rehash' boolean argument to the function
1596 silc_hash_table_alloc to indicate whether the hash table should
1597 auto-rehash when it thinks is appropriate time. It will
1598 increase the hash table size if the there is twice as much
1599 entries in the table than the size of the table, and will
1600 decrease the size if there are twice as less entries than
1601 the size of the table.
1603 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1605 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1607 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1609 * silc_idcache_purge_by_context deletes the entry now by context
1610 as it is supposed to do. Affected file lib/silccore/idcache.c.
1612 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1613 client is not anymore valid (WHOWAS givens the info) and not
1614 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1616 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1618 * Removed the `data' and `data_len' arguments from the ID Cache
1619 interfaces and added `name' argument. ID Cache does not handle
1620 anymore the binary data only a names associated with given ID.
1622 * When hashing a Client ID with silc_hash_id the entire ID is
1623 not hashed anymore, instead only the hash of the Client ID is
1624 hashed. This way we can access the Client ID from the cache
1625 with Client ID but with the hash of the ID (which is a hash of
1626 the nickname) as well without any difference in performance.
1628 Added also silc_idcache_find_by_id_one_ext to do one on one
1629 searching when we have the actual ID. Added also function
1630 silc_hash_client_id_compare. The affected files are
1631 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1633 * When hashing the name associated with a ID it is always done
1634 in lowercase. This way we can access the cache without worrying
1635 about case-sensitivity, even though, for example nicknames are
1638 * Fixed a bug in server with channel message sending. It put
1639 wrong ID type as destination ID. The affected file
1640 silcd/packet_send.c.
1642 * silc_idcache_del_by_context now deletes from all hash tables
1643 by context. Affected file lib/silccore/idcache.c.
1645 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1647 * Changed the client library to use the new ID Cache interface.
1648 Changes around the source tree.
1650 * Added silc_hash_table_rehash_ext to rehash with specific
1651 hash function. Affected file lib/silcutil/silchashtable.[ch].
1653 * Added silc_hash_string_compare to compare two strings in the
1654 hash table. Affected file lib/silcutil/silcutil.[ch].
1656 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1658 * Added new function silc_idcache_del_by_context into the
1659 lib/silccore/idcache.[ch].
1661 * Changed the server's ID list routines to use the new ID Cache
1662 interface. Changes around the source tree.
1664 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1666 * Added silc_hash_table_del[_by_context]_ext functions in to the
1667 lib/silcutil/silchashtable.[ch].
1669 Removed silc_hash_table_find_all* routines and added new
1670 silc_hash_table_find_foreach to replace them.
1672 Added silc_hash_table_replace_ext function as extended
1673 replacing function. Separated the simple hash table interface
1674 from the extended hash table interface in the file
1675 lib/silcutil/silchashtable.h.
1677 * Fixed minor bugs and changed it to use some of the new
1678 hash table functions in lib/silccore/idcache.c
1680 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1682 * Added new function silc_hash_table_find_all to return all keys
1683 in the hash table by the specified key. As the hash table is
1684 collision resistant it also makes it possible to have several
1685 duplicate keys in the hash table. This function may be used to
1686 find all of the keys from the hash.
1688 Added user_context arguments to the SilcHashFunction,
1689 SilcHashCompare and SilcHashDestructor to deliver user specified
1692 Added new fuctions silc_hash_table_find[_all]_ext to do
1693 extended lookup with specified hash and compare functions and
1694 specified user contexts.
1696 Added new function silc_hash_table_add_ext to add the key
1697 with specified hash function and user context.
1699 Added new function silc_hash_table_foreach to traverse all
1700 entrys in the hash table. Added SilcHashForeach callback
1703 Added new function silc_hash_table_del_by_context to delete
1704 the entry only if the context associated with the key matches.
1706 Affected files are lib/silcutil/silchashtable.[ch].
1708 * Removed silc_hash_[server/client/channel]_id and added just
1709 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1710 silc_hash_id_compare to compare two ID's using as the hash table
1711 comparison function. Added also silc_hash_data to hash
1712 binary data and silc_hash_data_compare to compare it.
1714 * Removed silc_idlist_find_client_by_hash as it is not needed
1715 anymore. Affected file silcd/idlist.[ch].
1717 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1718 to use internally the SilcHashTable. The new ID Cache is a lot
1719 faster than the old one. Some of the ID Cache interface was also
1720 rewritten and obsolete and stupid functions were removed.
1722 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1724 * Added entry_count field to the SilcHashTable to keep the number
1725 of the entries in the table. Implemented the function
1726 silc_hash_table_rehash. Added new function
1727 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1729 Fixed a minor bug in silc_hash_table_free.
1731 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1732 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1733 into the lib/silcutil/silcutil.[ch].
1735 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1737 * Implemented a collision resistant hash table into the
1738 lib/silcutil/silchashtable[ch]. See the header and the source
1739 for the SilcHashTable API.
1741 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1743 * Merged dotconf version 1.0.2 into lib/dotconf.
1745 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1747 * Do not compile anything in lib/silcsim/* if the SIM support
1748 is not enabled. The tree should now compile without problems
1751 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1753 * Compiled the SILC under cygwin. Compiled and tested briefly
1754 without problems. More tests needed. The SIMs didn't compile
1757 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1759 * Fixed possible crash in silc_get_username in the
1760 lib/silcutil/silcutil.c.
1762 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1764 * Fixed a va_arg in silc/client_ops.c.
1766 * Oops, RC5 routines were named AES and caused some problems
1767 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1769 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1771 * Added new SilcIDIP structure into the lib/silccore/id.h and
1772 replaced the old `ip' fields from all SILC ID's to that type.
1773 This is a step towards IPv6 support.
1775 The silc_id_get_len takes now the ID as an extra argument.
1776 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1777 both IPv4 and IPv6 based ID's.
1779 The affected files are lib/silccore/id.[ch] and other files
1780 around the tree using these routines.
1782 * Removed the ID length arguments in server from various
1783 silc_server_send_notify_* routines -> they are not needed
1786 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1788 * Fixed memory leak in silc_encode_pem_file in the file
1789 lib/silcutil/silcutil.c.
1791 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Check minor version as well in the SKE. Affected files are
1794 silcd/protocol.c and lib/silcclient/protocol.c.
1796 * Added --identifier option to the server so that an identifier
1797 can be when creating the public key for the server. Affected
1798 file is silcd/silcd.c.
1800 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1801 lib/silccrypt/silcpkcs.c.
1803 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1805 * Register default ciphers and stuff when using -C option with
1806 the server. Affected file sildc/silcd.c.
1808 * Put back the servers public key filename format, it is better
1809 than the new one. For now, the client keys are saved with the
1810 new filename format. The affected file silc/client_ops.c.
1812 * Implemented the Cipher API for the rest of the ciphers that
1813 did not implement it or implemented it the wrong way.
1815 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1817 * Register default ciphers and stuff when using the -S option
1818 in the client. Affected file silc/silc.c. Same also when
1819 creating new key pair with -C option.
1821 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1823 * Fixed the silc_verify_public_key client operation function to
1824 save the public keys differently. The fingerprint is now
1825 used as filename and not the hostname. This way also the
1826 client keys are saved uniquely and not with hostnames. The
1827 affected file is silc/client_ops.c.
1829 * Trimmed the silc_hash_fingerprint function to remove extra
1830 whitespaces from the end of the fingerprint. The affected
1831 file is lib/silccrypt/silchash.c.
1835 * Added silc_cipher_register_default function to register all
1836 default ciphers. It can be used when configuration files
1837 does not exist and the application does not want any specific
1838 ciphers in any specific order.
1840 The SilcDList is now used as silc_cipher_list dynamically
1841 allocated cipher list. Removed the static list all together
1842 and now all ciphers must be allocated to the dynamic list.
1843 The silc_cipher_alloc routine was changed to check only the
1846 All silc_cipher_* routines that used to return int returns
1849 The affected files lib/silccrypt/silccrypt.[ch].
1851 * The same thing was done to silc_hash_* as for silc_cipher_*
1852 routines. Affected files lib/silccrypt/silchash.[ch].
1854 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1855 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1856 Added also silc_pkcs_[un]register[_default] functions.
1857 Removed the data_context from the PKCS API.
1859 * Added silc_hmac_register_default function to register default
1860 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1861 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1862 to unregister all hmacs at once.
1864 * Register the default ciphers, hash functions, PKCSs and HMACs
1865 if client's configuration file does not exist. The affected
1868 * The client did not load the hash functions from the SIM
1869 modules at all. Added support for this. Affected file is
1870 silc/clientconfig.c.
1872 * When decoding public key with silc_pkcs_public_key_decode, check
1873 the supported algorithm only if PKCS are registered. Affected
1874 file lib/silccrypt/silcpkcs.c. The same was done with the
1875 silc_pkcs_private_key_decode.
1877 * Fixed the SILC List routines to keep the list always in order.
1878 It used to change the list's order when traversing the list but
1879 not it preserves the order. Affected file lib/trq/silclist.h.
1881 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1883 * Added the client library to use the SilcSocketConnection's
1884 reference counter (by silc_socket_dup) to prevent the bug that
1885 the socket object may be freed underneath async operation.
1887 * The name resolv library checking fixes in the configure.in.pre.
1890 * Created new version of the protocol drafts for future
1891 development. The -03 drafts are the ones that will be changed
1892 in the trunk now and the -02 will remain as they are.
1894 * Send list of CUMODE notifys to the router when announcing
1895 the channel users to the router. Affected file silcd/server.c.
1896 If the router receiving channel founder CUMODE for a channel
1897 that already has channel founder it will send CUMODE notify
1898 to the sender to remove the channel founder rights from the
1899 announced client. Affected file silcd/packet_receive.c.
1901 * The CUMODE notify may now use Server ID as well as the entity
1902 who changes the mode. Updated protocool specs.
1904 * Updated INSTALL and README files.
1906 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1908 * New web pages in the http://silc.pspt.fi. The pages was
1913 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1915 * Implemented the [DenyConnectin] config section in the server.
1916 Added silc_server_config_denied_conn to check whether incoming
1917 connection is denied. Affected file silcd/serverconfig.[ch].
1919 * Do not check the ports when checking the incoming configuration
1920 data if the port is 0, meaning any. Affected file is
1921 silcd/serverconfig.c.
1923 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1925 * Fixed buffer overflow in silc_string_compare in the file
1926 lib/silcutil/silcutil.c.
1928 * Fixed double free in silc_server_command_leave in the file
1931 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1933 * Fixed the version checking in the server. Affected file is
1936 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1938 * Fixed the configuration data fetching when accepting new
1939 connections in the server. Affected file silcd/server.c.
1941 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1943 * Added `sender_entry' argument to the function
1944 silc_server_packet_relay_to_channel so that we can check
1945 whether some destination actually belongs to the same route
1946 the sender belongs (ie, we must not resend the packet to the
1947 sender). Affected file silcd/packet_send.[ch].
1949 * Added `servername' field to the SilcClientEntry in the server
1950 to hold the name of the server where client is from. Affected
1951 file is silcd/idlist.h.
1953 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1955 * Moved the channel message encrypting in the router betwen
1956 router connections from silc_server_channel_message to the
1957 silc_server_packet_relay_to_channel since we want to check
1958 whether we have anybody channel before encrypting anything.
1959 Affected files silcd/packet_[receive/send].c.
1961 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Fixed the [AdminConnection] server config section to support
1964 multiple entries. Affected file silcd/serverconfig.c.
1966 * Added support into the server to check the validity of the
1967 incoming connection before executing any KE or authentication
1970 * The connection configuration is now saved to the KE and
1971 connection auth protocol contexts and not fetched anymore in
1972 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1974 * The local hosts listenning address and port is also resolved
1975 now when starting the server. We want to have the socket object
1976 to include the real address and port for the listener. Added
1977 new function silc_net_check_local_by_sock into the files
1978 lib/silcutil/silcnet.[ch].
1980 * Fixed a broadcast bug in server -> do not broadcast if we
1983 * Fixed a routing bug. Do not route broadcast packets ever.
1984 Broadcast packets must be processed always and not routed since
1985 they may be destined to some other host than yourself and thus
1986 would get routed without no good reason. Affected file is
1989 * Added function silc_server_config_is_primary_route to check
1990 whether primary router connection has been configured (a router
1991 configuration that we are initiating). If there is not, we
1992 will assume that there is only two routers in the SILC network
1993 and we will use the incoming router connection as our primary
1994 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1996 * Changed the order of the broadcasting. Broadcast _after_ the
1997 packet has been processed not before. Affected file is
2000 * Fixed a [ClientConnection] parsing bug. The port was never
2001 parsed correctly thus resulting to port 0. Affected file
2002 silcd/serverconfig.c.
2004 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
2005 argument and did not set the broadcast packet flag. Affected
2006 file silcd/packet_send.c. Fixed same bug in the function
2007 silc_server_send_notify as well.
2009 * If we receive NEW_ID packet for our own ID in the server, ignore
2012 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2016 * Removed the nickname from the Private Message Payload.
2017 Updated the code and the protocol specs.
2019 * Updated protocol specs for submitting to the IETF.
2021 * Tweaked the Random Number Generator a bit. Affected file
2022 lib/silccrypt/silcrng.c. Exported a new function
2023 silc_rng_[global]_add_noise which can be used to add more
2026 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2028 * Do not parse packets with different timeout when protocol
2029 is active -> may cause problem with rekey. Affected file
2032 * When server receives signoff notify it must not create
2033 new channel key if the client is on any channels since the
2034 sender of the signoff notify will create it.
2036 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Added printing of error messages during SKE protocol from the
2039 failure packet sent by server during SKE. Affected file
2042 * Removed the client's failure_callback handling with timeout
2043 and handle it immediately when received.
2045 * The SKE library returned wrong type in SUCCESS and FAILURE
2046 packets. They must be 32 bit MSB not 16 bit MSB.
2048 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Ok, rewrote the logic of the re-key and now it seems to work.
2051 I tested it on high traffic with frequent re-keys without
2052 problems. Added hmac_receive (and renamed hmac to hmac_send)
2053 in SilcClientConnection in lib/silcclient/client.h and
2054 in SilcIDListData in silcd/idlist.h. Also, removed the
2055 SilcPacketParserContext's cipher and hmac fields as they are
2056 not needed anymore and actually caused some problems when
2057 the ciphers and hmac's changed underneath the packet parser.
2059 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2061 * If re-key protocol is active then process the incoming packets
2062 synchronously since we must assure that icoming packets encrypted
2063 with the old key is processed before the new keys is set to
2064 use. This is true other packets than for REKEY packets.
2065 Affected file silcd/server.c. The same was done to client library
2066 as well, affected file lib/silcclient/client.c.
2068 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2070 * Fixed bug in client and server to accept the force send if
2071 the packet is send from silc_[server/client]_packet_process
2072 function. Otherwise the packets are never delivered, oops.
2074 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2076 * Disable force sending of packets when REKEY protocol is active.
2077 We must assure that no packet is sent directly when rekey is
2078 performed. All packets must be sent through packet queue.
2079 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2080 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2081 function is silc_[server/client]_packet_send_real to check
2084 * Replaced the SIM paths from example config files to
2085 /usr/local/modules. Also, make install creates now
2086 /usr/local/silc/logs directory to hold all the SILC server
2089 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2091 * Made the configure.in.pre work on Solaris. Patch by salo.
2093 * Made all ciphers compatible with non-x86 machines. Defined
2094 CBC mode macros into lib/silccrypt/ciphers_def.h.
2096 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2098 * Fixed the make install.
2100 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2102 * When MAC computation fails the silc_packet_decrypt returned 0
2103 even though it was supposed to return -1. Fixed this. The
2104 affected file is lib/silccore/silcpacket.c.
2106 * Do not replace the config files in /etc/silc (in make install)
2107 if they already exist. Affected file ./Makefile.am.
2109 * Do not send re-key packets immediately but through packet queue.
2110 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2112 * Changed silc_net_check_host_by_sock to return FALSE if the
2113 IP/DNS could not be resolved. Though, it returns the IP address
2114 now even if it could not resolve it (but returns also FALSE).
2115 Affected file lib/silcutil/silcnet.[ch].
2117 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2119 * Added silc_pkcs_decode_identifier to decode the public key's
2120 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2121 Added also silc_pkcs_free_identifier. Added also new context
2122 SilcPublicKeyIdentifier.
2124 * Added -S option to the silc client. It is used to dump the
2125 contents of the specified public key file.
2127 * Changed the PKCS api to return the public key length when
2128 setting the public key.
2130 * Fixed a fatal bug in the public and private key file loading.
2131 Affected file lib/silccrypt/silcpkcs.c.
2133 * Execute the packet parsing for client with zero (0) timeout
2134 if the protocol is active. Affected file silcd/server.c.
2136 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2138 * Made the key generation options to the silcd program. Added
2139 -C option, equivalent to client's option.
2141 * Added new [ServerKeys] config section to the server. It
2142 configures the server's public and private key.
2144 * Defined generic Public Key Payload into the protocol
2145 specification to send specific type of public keys and
2148 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2149 public key or certificate.
2151 * Implemented the GETKEY command to the server and to the
2152 client library and on user interface.
2154 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2156 * Made preliminary `make install' work.
2158 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2160 * Added SilcServerRekey context into silcd/idlist.h.
2162 * Added the PFS support as defined in the specification to the
2163 SKE protocol. Affected files lib/silcske/*.c.
2165 * Added `ske_group' field to the SilcServerRekey context to hold
2166 the number of the SKE group that is used with PFS in re-key.
2167 Affected file silcd/idlist.h.
2169 * Added PFS re-key support to the server. Affected file is
2172 * Added silc_protocol_cancel to cancel execution of the next
2173 state of the protocol. Affected file is
2174 lib/silccore/silcprotocol.[ch].
2176 * Added the re-key support with and without PFS to the client
2177 library. Re-key is performed once in an hour, by default.
2179 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2180 Added silc_client_rekey_callback and silc_client_rekey_final.
2181 Affected files are lib/silcclient/protocol.[ch] and
2182 lib/silcclient/client.[ch].
2184 * Removed the `hmac_key' and `hmac_key_len' fields from the
2185 SilcClientConnection structure; not needed. Affected file is
2186 lib/silcclient/client.h.
2190 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2192 * Do not ask whether user wants to use the negotiated private key
2193 for private messages, just use it. Affected file is
2194 silc/local_command.c.
2196 * Added `send_enc_key' and `enc_key_len' fields to the
2197 SilcIDListData structure since they are needed in the re-key
2198 phase. Affected file is silcd/idlist.[ch].
2200 * Implemented the simple re-key protocol into the server.
2201 Affected files silcd/server.c and silcd/protocol.[ch]. The
2202 re-key will be performed once in an hour, by default.
2204 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2205 Added silc_server_rekey, silc_server_rekey_callback and
2206 silc_server_rekey_final.
2208 * Removed Tunneled flag from the protocol. Updated the code
2209 and the specifications.
2211 * Adde `pfs' field to the SilcIDListData to indicate whether
2212 the PFS is to be performed in the re-key. Affected file is
2215 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2218 int64 of at least the xintXX size. If void * is less that 4
2219 bytes uint32 * will be used. Defined bool as boolean.
2221 * Changed _ALL_ unsigned long and unsigned int to uint32,
2222 unsgined short to uint16 in the source tree.
2224 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2225 not handle clients that has entry->data.registered == FALSE.
2226 They are not in the network anymore. Affected file is
2229 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2231 * Implemented the sending of the SERVER_SIGNOFF notify in the
2232 server. Affected file is silcd/server.c.
2234 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2235 Added also silc_notify_payload_encode_args into the
2236 lib/silccore/silcnotify.[ch].
2238 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2239 Affected file silcd/packet_receive.c.
2241 * Implemented the SERVER_SIGNOFF notify handling in the client
2242 library. Affected file lib/silcclient/client_notify.c. Also,
2243 implemnted the printing of the SERVER_SIGNOFF info to the
2244 application. Affected file silc/client_ops.c.
2246 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2247 if the deleting was successful. Affected file silcd/idlist.[ch].
2249 * Added support for public key authentication in the connection
2250 authentication protocol in the client library. Affected file
2251 lib/silcclient/protocol.c.
2253 * Changed the server's silc_idlist_get_clients_by_* interface
2254 to support already allocated array so that new entries may be
2255 added to pre-allocated array. Affected file silcd/idlist.[ch].
2256 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2257 and command replies.
2259 * All command reply functions in the server now calls the
2260 pending command callback even if error occured. This way the
2261 error will be delivered to the client as well. Affected files
2262 silcd/command.c and silcd/command_reply.c.
2264 * Fixed INFO command to return local server's info if no server
2265 was provided. Affected file lib/silcclient/command.c.
2267 * Removed RESTART command for good. Updated the code and the
2270 * Rewrote parts of the task system. It is a bit simpler now.
2271 Removed unsued task priorities. The affected files are
2272 lib/silcutil/silctask.[ch].
2274 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2276 * Moved the USERS printing from the library to the application.
2277 Affected files lib/silcclient/command.c and silc/client_ops.c.
2279 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * Added channel key re-key support. The re-key is perfomed
2284 only by the router and is done once in an hour. Added `rekey'
2285 field to the SilcChannelEntry in the server. Affected files
2286 silcd/server.c and silcd/idlist.h.
2288 * Added silc_task_unregister_by_context into the file
2289 lib/silcutil/silctask.[ch].
2291 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2293 * Added SILC_UMODE_GONE mode to indicate when the client is not
2294 present in the SILC network. Added also support to the local
2295 command AWAY that will set this mode. Added support of showing
2296 "xxx is gone" in WHOIS command. The USERS command shows the
2297 gone status as well.
2299 * Fixed setting server and router operator privileges in the
2300 server's UMODE command. Affected file silcd/command.c.
2302 * Merged the SKE KE1 and KE2 payloads into one payload. The
2303 new KE payload is equivalent to the old KE2 payload.
2305 Cleaned up the SKE Start Payload parsing. It now uses the
2306 simple buffer unformatting to do the parsing. A lot faster
2309 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2310 to the SKE that is used to indicate whether both of the SKE
2311 parties should perform authentication. By default only the
2312 responder performs authentication. By setting this flag also
2313 the initiator must do authentication. By default it is unset
2314 since in normal SKE case, client to server connection, only
2315 the responder should do authentication. When doing SKE between
2316 two clients both should perform authentication. Updated the
2317 code and the protocol specs.
2319 * A little fix to IDENTIFY command in the server. Search the
2320 client first by hash not nickname. Affected file is
2323 * Fixed the silc_client_close_connection to support closing
2324 the client to client connections wihtout deleting too much
2325 data. Affected file lib/silcclient/client.c.
2327 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2328 are received if protocol used to be active but is not anymore
2329 the application would crash due to NULL pointer dereference.
2330 Affected files silcd/server.c and lib/silcclient/client.c.
2332 * Added `hash' field to the SilcClientConnection to include
2333 the hash function negotiated in the SKE protocol.
2335 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2336 to set the channel founder authentication data. A client can
2337 claim the founder rights later by providing the authentication
2338 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2339 This way the channel founder can regain the channel founder
2340 privileges even it is left the channel. This works only on
2341 local server and the client must be connected to the same
2342 server to be able to regain the founder rights. Updated the
2343 protocol specs accordingly.
2345 Added support to the CMODE command in the client to set the
2346 founder auth data. Read the README to see how to set it.
2348 Added support to the CUMODE command to claim the founder
2349 rights. Read the README to see how to do it.
2351 Added support for the founder authentication to the Channel
2352 Entry in the server. Affected file silcd/idlist.h.
2354 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2355 server's CMODE command. Affected file silcd/command.c.
2357 * Added the following new functions into lib/silccore/silcauth.[ch]:
2358 silc_auth_get_method and silc_auth_get_data.
2360 * The server now saves the remote hosts public key to the
2361 SilcIDListData pointer. Affected file silcd/protocol.c.
2363 * The normal server now does not remove the channel entry from
2364 the cache if the founder authentication data is set. It used
2365 to remove it if the founder was the last one on the channel on
2366 the server and left the channel. The auth data is saved and
2367 if the channel is re-joined later the old entry is used with
2368 the old auth data. Affected files silcd/command_reply.c and
2371 * Removed the `pkcs' field from the SilcIDListData structure
2372 in the server; it is not used. Affected file silcd/idlist.h.
2374 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2376 * Fixed packet processing on slow links. Partial packets were
2377 never re-processed because the incoming data buffer was cleared
2378 by the application. Application must not directly clear the
2379 sock->inbuf, the packet processing routines handle it. Fixed
2380 this in client library and in server.
2382 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2384 * Fixed the WHOIS and IDENTIFY send reply function to really
2385 check whether to send list or just one entry. Affected file
2388 * Cleaned up the LEAVE command's channel key distribution. The
2389 affected file silcd/command.c.
2391 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2392 can enforce the channel mode as well. In that case the ID
2393 includes the ID of the server. The code now enforces the
2394 mode change if the router have different mode than the server.
2396 * The notify client operation with CMODE_CHANGE notify can now
2397 return NULL client_entry pointer if the CMODE was not changed
2398 by client. Application must check for this.
2400 * Added <Server ID> argument to INFO command to support server
2401 info fetching by Server ID.
2403 * Added silc_server_announce_get_channel_users to get assembled
2404 packets of channel users of the specified channel. Affected
2405 file silcd/server.[ch].
2407 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2408 was freed underneath the ID Cache.
2410 * Re-announce clients when the server received CHANNEL_CHANGE
2411 notify from the router. Affected file silcd/packet_send.c.
2413 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2415 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2416 crashed since it did not handle the fact that there is no cipher
2417 called "3" and didn't check the error condition. Now fixed.
2419 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2420 flag. It can be used to send message requests.
2422 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2424 * Implemented the RESTART command in the client.
2426 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2427 notice type messages. Added notice printing to the user
2430 * The channel keys are not re-generated if the channel's mode
2431 is PRIVKEY, ie private key on the channel exists. Affected
2432 files silcd/server.c and silcd/command.c.
2434 * Fixed a little bug in channel message delivery when channel
2435 private keys are set in the server. Affected file is
2436 silcd/packet_send.c.
2438 * Changed the setting on channel->on_channel = TRUE from the
2439 silc_client_save_channel_key to the JOIN command reply. The
2440 key payload is not received if the private channel key is set.
2441 Affected file lib/silcclient/command_reply.c and the
2442 lib/silcclient/client_channel.c.
2444 * When the CMODE_CHANGE notify is sent and the channel private
2445 key mode is removed the channel key must be re-generated in
2446 other cells as well. Added this support for the router in the
2447 silcd/packet_receive.c.
2449 * Added new local command NOTICE to send notice message on
2450 channel. Affected file silc/local_command.[ch].
2452 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2454 * Added new local command ME to the client. It is used to send
2455 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2456 some action. Affected file silc/local_command.[ch].
2458 * Changed channel_message and private_message client operations
2459 to deliver the message flags to the application. Added also
2460 the `flags' arguments to the silc_client_send_channel_message
2461 and silc_client_send_private_message functions. Affected file
2464 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2466 * Redefined the Private Message Payload to support private message
2467 keys and to support the new private message flags. Updated
2468 the protocol specs. Flags makes it possible to have for example
2469 CTCP style messages.
2471 * Added new type SilcPrivateMessagePayload and defined an API
2472 for it in the lib/silcclient/silcprivate.[ch].
2474 * Tested private message private keys successfully. Tested the
2475 private message key set, unset and list commands with the new
2478 * Redefined the Channel Message Payload to include the channel
2479 message flags (equal with private message flags) to support
2480 for example CTCP style messages.
2482 * Defined some of the message (for channel and private message)
2483 flags. Updated the protocol specs and added the flags to the
2484 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2486 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2488 * Added SilcKeyAgreementStatus type to the key agreement routines
2489 to indicate the current status and error if one occured.
2490 The status types are defined in the lib/silcclient/silcapi.h.
2492 * Added new local command KEY that is used to set and unset private
2493 keys for channels, set and unset private keys for private messages
2494 with remote clients and to send key agreement requests and
2495 negotiate the key agreement protocol with remote client. The
2496 key agreement is supported only to negotiate private message keys,
2497 it currently cannot be used to negotiate private keys for channels,
2498 as it is not convenient for that purpose.
2500 * Fixed a minor pending callback setting bug in the function
2501 silc_client_get_client_by_id_resolve, now the function works.
2502 Affected file lib/silcclient/idlist.c.
2504 * Added function silc_net_get_local_port to get local bound
2505 port by socket. Added to lib/silcutil/silcnet.[ch].
2507 * Added `sockets' and `sockets_count' fields to the SilcClient
2508 object. They hold the sockets of the listenning sockets in
2509 the client. Listenning sockets may be for example the key
2510 agreement server. Affected file lib/silcclient/client.[ch].
2511 Added functions the silc_client_add_socket and the
2512 silc_client_del_socket. They are exported to the application
2515 * Added ~./silc/clientkeys to support other client's public keys.
2517 * Renamed verify_server_key client operation to verify_public_key
2518 and added one argument to indicate the type of the connection
2519 (server, client etc.).
2521 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2523 * Added silc_server_connection_auth_request to handle the
2524 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2525 silcd/packet_receive.[ch].
2527 * Added silc_server_send_connection_auth_request into the
2528 silcd/packet_send.c to send the connection auth request packet.
2530 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2533 * Fixed the public key authentication in responder side in the
2534 server. The `auth_data' pointer includes the SilcPublicKey
2535 not the path to the public key. Affected file silcd/protocol.c.
2537 * Implemented the public key authentication in the initiator side
2538 in the server. Affected file silcd/protocol.c.
2540 * Removed the [RedirectClient] config section from the server
2541 configuration. Is not needed and I don't want to implement it.
2543 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2545 * Cleaned up the CMODE command in the server. It now works
2546 correctly and supports all the modes defined in the protocol.
2547 Affected file is silcd/command.c.
2549 * Added `hmac_name' field to the SilcChannelEntry in the server
2550 to hold the default HMAC of the channel. It can be set when
2551 creating the channel (with JOIN command). Affected files
2554 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2555 type to indicate the change of the current cipher and hmac
2556 on the channel. Client can safely ignore the <cipher> argument
2557 (if it chooses to do so) since the CHANNEL_KEY packet will
2558 force the channel key change anyway. The <hmac> argument is
2559 important since the client is responsible of setting the new
2560 HMAC and the hmac key into use.
2562 * Fixed the CMODE command in the client library as well.
2564 * Tested CMODE command in router environment successfully.
2566 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2568 * Show the version of the remote client (or server) when connecting
2569 to the server. It is logged to the log file. Affected file
2570 is silcd/protocol.c.
2572 * Fixed the KILLED notify handling in the client library. The
2573 client must be removed from all channels when receiving the
2576 Also, do not remove the client entry when giving the KILL
2577 command but when the KILLED notify is received.
2579 * Removed silc_idlist_find_client_by_nickname from the server.
2580 Not needed anymore. Affected files silcd/idlist.[ch].
2582 * Implemented the CHANNEL_CHANGE notify type handling to the
2583 server. Affected file silcd/server.c.
2587 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2589 * Added silc_server_send_notify_invite to send the INVITE
2590 notify between routers.
2592 * Implemented the INVITE command correctly to the server.
2594 * Implemented the INVITE notify type handling in the server.
2596 * Implemented the INVITE command to the client library and on the
2599 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2601 * Added function silc_server_get_client_resolve to find the
2602 client entry by ID from all ID lists and then resolve it
2603 (using WHOIS) if it cannot be found. Affected file is
2606 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2608 * Implemented the BAN command to the client library.
2610 * The JOIN command in the server now checks the invite list
2613 * Changed the silc_command_reply_payload_encode_va and the
2614 silc_command_payload_encode_va to support that if argument is
2615 NULL it ignores and checks the next argument. Affected file
2616 lib/silccore/silccommand.c.
2618 * Added silc_server_send_notify_ban to send the BAN notify
2619 type between routers.
2621 * Chaned the silc_notify_payload_encode to support that if
2622 argument is NULL it ignores and checks the next argument.
2623 Affected file lib/silccore/silcnotify.c.
2625 * Tested ban lists in router environment successfully.
2627 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2629 * Implemented BAN command to the server, in silcd/command.[ch].
2631 * Removed the BAN and INVITE_LIST modes from the CMODE command
2634 * Added function silc_string_match to regex match two strings.
2635 Affected files lib/silcutil/silcutil.[ch].
2637 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2639 * Redefined parts of the SilcChannelEntry in the server to support
2640 the new ban and invite lists.
2642 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2644 * Redefined the INVITE command. The same command can be used to
2645 invite individuals to the channel but also to manage the invite
2646 list of the channel (to add to and remove from the invite list).
2647 Updated the protocol specs.
2649 * Added new command SILC_COMMAND_BAN that can be used to manage
2650 the ban list of the channel. Updated the protocol specs.
2652 * Removed the channel modes: the SILC_CMODE_BAN and the
2653 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2654 in the CMODE command. The equivalent features are now available
2655 using INVITE and BAN commands. Updated the protocol specs.
2657 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2658 in the network about change in the current ban list. The notify
2659 type is not used by the client.
2661 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2662 support the invite lists.
2664 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2666 * Added new function silc_string_regexify that converts string
2667 including wildcard characters into regex string that can
2668 be used by the GNU regex library. Added into the file
2669 lib/silcutil/silcutil.[ch].
2671 Added silc_string_regex_combine to combine to regex strings
2672 into one so that they can be used as one regex string by
2673 the GNU regex library. Added into the file
2674 lib/silcutil/silcutil.[ch].
2676 Added silc_string_regex_match to match two strings. It returns
2677 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2679 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * Imported GNU regex to the soruce tree into lib/contrib.
2682 Fixed some compiler warning from the regex.c.
2684 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2686 * Fixed MOTD command in the server to work in router environment.
2688 * Fixed the MOTD command in the client library to support
2689 the server argument in the command.
2691 * Added `nickname_len' argument to the silc_idlist_add_client
2692 in the server, as the `nickname' argument may be binary data
2695 * Added silc_idlist_get_channels to return all channels from
2698 * Implemented LIST command to the server. Affected file is
2701 * Implemented the LIST command to the client library and on the
2704 * Added [<user count>] argument to the LIST command reply.
2705 With private channels the user count is not shown.
2707 * Updated TODO and README.
2709 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2711 * The client entry's data.registered must be TRUE even with
2712 global client entry on global client list. The data.registered
2713 is used to check whether the client is anymore in the network,
2714 for example with WHOWAS command so it must be valid.
2716 * Fixed the WHOWAS command in the server. It now actually works
2717 in router environment. Added function into silcd/command_reply.c
2718 silc_server_command_reply_whowas_save.
2720 * Added silc_idlist_purge function to the silcd/idlist.c
2721 to periodically purge the ID Cache.
2723 * Fixed INFO command in the server. It works now in router
2724 environment. Added <server name> argument to the INFO command
2725 reply. Updated the protocol specs.
2727 * Fixed minor bug in silc_idcache_purge to not purge if the
2728 expire value is zero.
2730 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2731 they were buggy because of the WHOWAS information.
2733 * Fixed local command MSG to handle the async resolving of
2734 the remote client properly. It used to fail the first MSG.
2735 Affected file silc/local_command.c.
2737 * Added `data_len' field to SilcIDCache context.
2739 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2741 * Update TODO. Todo in commands in the server.
2743 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2745 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2746 used by routers as broadcast packet to inform other routers
2747 about the changed user mode.
2749 Implemented the notify handling in the server. Affected file is
2750 silcd/packet_receive.c. Added the function
2751 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2753 * Added new generic Channel Payload and deprecated the New Channel
2754 Payload. The New Channel Payload is now the generic Channel
2757 * Added new argument `mode' to the silc_server_send_new_channel
2758 as it is required in the Channel Payload now.
2760 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2761 and created a new and real SilChannelPayload to represent the
2762 new generic Channel Payload. Implemented the encode/decode
2763 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2765 * Added silc_server_get_client_channel_list to return the list
2766 of channels the client has joined for WHOIS command reply.
2767 Affected file silcd/server.[ch].
2769 * Implemented the channel list sending in the WHOIS command reply
2770 in server and in the client.
2772 Implemented the channel list displaying on the user interface
2773 as well. Affected file silc/client_ops.c.
2775 * Added silc_channel_payload_parse_list to parse list of Channel
2776 Payloads. It returns SilcDList list of SilcChannelPayloads.
2777 Client for example can use this function to parse the list of
2778 channels it receives in the WHOIS command reply. The caller
2779 must free the list by calling silc_channel_payload_list_free.
2780 Affected files lib/silccore/silcchannel.[ch].
2782 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2784 * Added one new argument <user mode> to the WHOIS command reply
2785 to return the mode of the user in SILC. Updated the protocol
2788 Implemented it to the server and client.
2790 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2792 * Fixed the mode printing on the user interface on joining.
2793 Affected file silc/client_ops.c.
2795 * Implemented the UMODE command and user modes in general to the
2796 client library and to the user interface.
2798 * Implemented the UMODE command to the server.
2800 * The server now sends UNKNOWN_COMMAND error status if client sends
2801 unknown command. Affected file silcd/command.c.
2803 * All server commands now handle the command identifier the right
2804 way when sending the command reply to the client. The client can
2805 use to identify the command replies with the identifier.
2807 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2809 * Added silc_server_get_client_route to resolve the route to
2810 the client indicated by the client ID. Affected file is
2813 * Added silc_server_relay_packet as general function to relay
2814 packet to arbitrary destination. This deprecates functions
2815 like _send_private_message_key, _relay_notify etc. Affected
2816 file is silcd/packet_send.[ch].
2818 Removed silc_server_send_key_agreement,
2819 silc_server_send_private_message_key and
2820 silc_server_packet_relay_notify functions from the file
2821 silcd/packet_send.[ch].
2825 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2826 server. Affected file silcd/packet_receive.[ch].
2828 * Implemented the KILL command to the client. Implemented the
2829 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2830 Affected files lib/silcclient/command[_reply].c and
2831 lib/silcclient/client_notify.c. Implemented the KILL notify
2832 printing in the user inteface.
2834 * Fixed a lot silc_parse_nick memory leaks from the client
2835 library in the file lib/silcclient/command.c.
2837 * Changed the silc_server_send_notify_on_channels's `sender'
2838 argument from SilcSocketConnection to SilcClientEntry to
2839 check the sender as entry and not as connection object and not
2840 to send to the client provided as argument. The affected file
2841 is silcd/packet_send.[ch].
2843 * The notify packets that are destined directly to the client used
2844 to not to be processed by the server. Now changed that and the
2845 server processes all notify packets. After relaying the packet
2846 to the client the notify packet is processed in the server.
2848 * The silc_server_free_client_data now checks whether there is
2849 pending outgoing traffic for the client and purges the data to
2850 the network before removing the client entry.
2852 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2854 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2855 an client is killed from the SILC Network. Updated the protocol
2858 Added new function silc_server_send_notify_killed to the
2859 silcd/packet_send.[ch].
2861 * Added function silc_server_packet_relay_notify to relay notify
2862 packets that are destined directly to a client. In this case
2863 the server does not process the notify packets but merely relays
2864 it to the client. Affected file silcd/packet_send.[ch].
2866 Added also silc_server_packet_process_relay_notify to check
2867 whereto relay the notify. Affected file is
2868 silcd/packet_receive.[ch].
2870 * Implemented the KILL command to the server.
2874 * Added the backup schema desgined last fall to the protocol
2875 specs for everyone to see. The specification is in the
2876 *-spec-xx.txt draft and the packet type definitions for the
2877 backup routers is in *-pp-xx.txt draft. Thusly, added also
2878 new packet type SILC_PACKET_CELL_ROUTERS.
2880 * A big security problem in the implementation discovered. The
2881 signoff of an client did not cause new channel key generation
2882 which it of course should've done. The channel keys must be
2883 always re-generated when client leaves (or signoffs) the channel.
2884 The silc_server_remove_from_channels funtion now handles
2885 the channel key re-generation.
2887 * Added `sender' argument to the silc_server_send_notify_on_channels
2888 to not to send the client provided as argument. Affected file
2889 silcd/packet_send.[ch].
2891 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2893 * Implemented OPER and SILCOPER commands into the server and
2896 * Added silc_auth_verify and silc_auth_verify_data to verify
2897 the authentication directly from the authentication payload.
2898 It supports verifying both passphrase and public key based
2899 authentication. Affected file lib/silccore/silcauth.[ch].
2901 * Added `hash' field to the SilcIDListData structure. It is the
2902 hash negotiated in the SKE protocol. Affected file is
2905 * Slight redesigning of the SilcAuthPayload handling routines.
2906 Do not send SilcPKCS but SilcPublicKey as argument.
2908 * Implemented the public key authentication support to the
2909 serverconfig. The public key is loaded from the provided path
2910 and saved as authentication data to void * pointer. Thus,
2911 changed the unsigned char *auth_data to void *auth_data;
2913 * Fixed SHUTDOWN command to send the reply before the server
2914 is shutdown. :) Affected file silcd/command.c.
2916 * Fixed fatal bug in CONNECT command. The hostname was invalid
2917 memory and server crashed. Affected file silcd/command.c.
2919 * Fixed fatal bug in CLOSE command. The server_entry became
2920 invalid but was referenced later in the command. Affected file
2923 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2925 * Fixed fatal bug in failure packet handling. Server ignored
2926 the failure and thus crashed when it came.
2930 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2932 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2933 that the command may be executed only once in (about) 2 seconds.
2934 The old SILC_CF_LAG flag is same but allows command bursts up
2935 to five before limiting.
2937 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2938 server code. Various commands now includes the CF_LAG_STRICT
2939 flag to disallow any kind of miss-use of the command.
2941 * Fixed the silc_buffer_unformat to not to allocate any data
2942 if the length of the data is zero. It used to allocate the
2943 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2945 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2947 * Changed the format of AdminConnection configuration section
2948 in the server. Added username of the admin to the format.
2949 Affected files silcd/serverconfig.[ch].
2951 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2952 to return admin configuration data by host, username and/or
2955 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Implemented WHOWAS command to the server. Added the functions:
2959 silc_server_command_whowas_parse,
2960 silc_server_command_whowas_send_reply,
2961 silc_server_command_whowas_from_client and
2962 silc_server_command_whowas_from_server
2964 * Added <Client ID> argument to the WHOWAS command reply. Updated
2965 the protocol specs accordingly.
2967 * Implemented WHOWAS command and command_reply to the client
2970 Implemented the WHOWAS printing on the user interface.
2972 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2974 * Added new argument to the WHOWAS command reply, the real name.
2975 It is an optional argument. Updated the protocol specs.
2977 * Added SilcIDCacheDestructor callback that is registered when
2978 the SilcIDCache is allocated. The callback is called when
2979 an cache entry in the ID Cache expires, or is purged from the
2980 cache. Added into lib/silccore/idcache.[ch].
2982 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2983 to destruct the client entries when the cache entry expires.
2984 Other ID Cache's in server and in the client library ignores
2987 * If the ID Cache entry's `expire' field is zero then the entry
2988 never expires. Added boolean `expire' argument to the
2989 silc_idcache_add function in the lib/silccore/idcache.[ch].
2990 If it is TRUE the default expiry value is used.
2992 * Added silc_server_free_client_data_timeout that is registered
2993 when client disconnects. By default for 5 minutes we preserve
2994 the client entry for history - for WHOWAS command.
2996 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2998 * Added support to the server to enforce that commands are not
2999 executed more than once in 2 seconds. If server receives
3000 commands from client more frequently, timeout is registered
3001 to process the commands. Affected file silcd/command.c.
3002 Added new function silc_server_command_process_timeout.
3004 * Changed NICK_NOTIFY handling in client library to check that
3005 if the client's nickname was changed, so there is no need to
3006 resolve anything from the server.
3008 * Removed error printing from the WHOIS and IDENTIFY commands.
3009 If error occurs then it is ignored silently in the client library.
3010 The application, however, may map the received error to
3011 human readable error string. The application currently maps
3012 the NO_SUCH_NICKNAME error to string.
3014 * Made the command status message public to the application. Moved
3015 them from lib/silcclient/command_reply.c to
3016 lib/silcclient/command_reply.h. The application can map the
3017 received command status to the string with the
3018 silc_client_command_status_message function.
3020 * Added check to the server to check that client's ID is same
3021 as the Source ID in the packet the client sent. They must
3024 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3026 * Added dist-bzip hook to the Makefile.am to make bzip2
3027 compressed distributions.
3029 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3031 * Server now enforces the maximum length for the nickname and
3032 the channel as protocol specification dictates. 128 bytes for
3033 nickname and 256 bytes for channel name.
3035 * Moved the WHOIS printing to the application. The client libary
3036 does not print out the WHOIS information anymore, the application
3037 must do it. Renamed silc_client_command_reply_whois_print to
3038 the silc_client_command_reply_whois_save.
3040 The client's idle time is also sent to the application now, and
3041 the idle is shown on screen.
3043 * Added silc_client_command_reply_identify_save to save the
3044 received IDENTIFY entries.
3046 * Do not check for channel private keys in message sending and
3047 reception if the channel does not have the PRIVKEY mode set.
3048 Affected file lib/silclient/client_channel.c.
3050 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3052 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3053 just surfaced after chaning the JOIN procedure.
3055 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3057 * Added silc_client_get_clients_by_list to get client entries
3058 from Client ID list, that is returned for example by JOIN
3059 and USERS command replies. The application should use this
3060 function for example when JOIN command reply is received to
3061 resolve the clients already on the channel (library does not
3062 do that anymore as USERS command reply is not used in the JOIN
3063 procedure anymore). Affected files lib/silcclient/silcapi.h and
3064 lib/silcclient/idlist.c.
3066 * JOIN command reply and USERS command reply returns now SilcBuffer
3067 pointers instead of unsigned char pointers when returning
3068 the client list and mode list.
3070 * Added <Client ID> argument to the JOIN command reply, mainly
3071 for the server to identify for which client the command was
3072 originally sent. Updated protocol specs accordingly.
3074 * Added SilcDlist private_key pointer to the SilcChannelEntry
3075 in the client to support the channel private keys. Affected
3076 file is lib/silcclient/idlist.h.
3078 * Added SilcChannelPrivateKey argument to the function
3079 silc_client_send_channel_message so that application can choose
3080 to use specific private ke if it wants to. If it is not provided,
3081 the normal channel key is used, unless private keys are set.
3082 In this case the first (key that was added first) is used
3083 as the encryption key.
3085 * Implemented the support for channel private key handling.
3086 Implemented the following functions:
3088 silc_client_add_channel_private_key,
3089 silc_client_del_channel_private_keys,
3090 silc_client_del_channel_private_key,
3091 silc_client_list_channel_private_keys and
3092 silc_client_free_channel_private_keys
3094 Affected file lib/silcclient/client_channel.c.
3096 * Added the support for the private keys in the channel message
3097 sending and encryption and in the message reception and
3098 decryption. Affected funtions are
3099 silc_client_send_channel_message and silc_client_channel_message.
3101 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3103 * Added SKE's key verify callback to the client library's
3104 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3106 * Removed the statement that server (or router) must send USERS
3107 command reply when joining to the channel so that the client
3108 knows who are on the channel. Instead, the client list and
3109 client's mode list is now sent in the JOIN command reply to the
3110 client who joined channel. This is better solution.
3112 * Added function silc_server_get_users_on_channel and function
3113 silc_server_save_users_on_channel to the silcd/server.[ch].
3115 * Removed function silc_server_command_send_users from the
3118 * Do not show topic on the client library anymore. The topic is
3119 sent in the command reply notify to the application and the
3120 application must show the topic now.
3122 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3124 * Added client searching by nickname hash into the IDENTIFY and
3125 WHOIS commands in the server as they were clearly missing from
3126 them. Affected file is silcd/command.c.
3128 * Fixed a bug in private message receiving in the client library.
3129 The remote ID was freed and it wasn't supposed, now it is
3132 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3134 * Minor fix to the channel payload; allocate the data area, as it
3135 needs to be of specific length.
3137 * If the key agreement port is zero then the operating
3138 system will define the bound port. Affected files are
3139 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3141 * Added new function silc_channel_payload_decrypt into the file
3142 lib/silccore/silcchannel.[ch].
3144 * Moved the channel message etc, check from silc_packet_decrypt
3145 to applications. The library calls now a generic
3146 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3147 when the packet is either normal or special. This was done to
3148 allow more wide range of checking that was not allowed when
3149 the code was in library. Now applications can do virtually any
3150 checks to the packet and return to the library the decision how
3151 the packet should be processed. Affected files are
3152 lib/silccore/silcpacket.[ch].
3154 Added silc_server_packet_decrypt_check to the server and
3155 silc_client_packet_decrypt_check to the client library.
3157 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3158 to send with specified source and destination information.
3160 * Channel message delivery between routers was broken after the
3161 channel key distribution was fixed earlier. The channel key
3162 was used be to distributed to other routers as well which is not
3163 allowed by the protocol. Now this is fixed and channel keys
3164 really are cell specific and the channel message delivery between
3165 routers comply with the protocol specification.
3167 * Fixed various commands in server to check also the global list
3168 for the channel entry and not just the local list. The affected
3169 file silcd/command.c.
3171 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3173 * Added assert()s to buffer formatting and unformatting routines
3174 to assert (if --enable-debug) when error occurs. Affected
3175 file: lib/silcutil/silcbuffmt.c.
3177 * Changed to auto-reconnect to check whether the remote host is
3178 router and register the re-connect timeout if it is. It used
3179 to check that whether we are normal server, but router must do
3180 auto-reconnect with another router as well. Affected file
3183 * Removed the [<key len>] option from CMODE command as the cipher
3184 name decides the key length, nowadays. See the defined ciphers
3185 from the protocol specification.
3187 * Added [<hmac>] option to the CMODE command to define the HMAC
3188 for the channel. Added SILC_CMODE_HMAC channel mode.
3190 * Added [<hmac>] option for the JOIN command so that user can
3191 select which HMAC is used to compute the MACs of the channel
3194 * Added Hmac field to the Channel Message Payload. The integrity
3195 of plaintext channel messages are now protected by computing
3196 MAC of the message and attaching the MAC to the payload. The
3197 MAC is encrypted. Now, it is clear that this causes some
3198 overhead to the size of the packet but rationale for this is that
3199 now the receiver can verify whether the channel message decrypted
3200 correctly and also when private keys are set for the channel the
3201 receiver can decrypt the packet with several keys and check from
3202 the MAC which key decrypted the message correctly.
3204 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3205 lib/silccrypt/silccipher.[ch].
3207 * Added silc_hash_len to return the digest length into the
3208 lib/silcrypt/silchash.[ch].
3210 * Rewrote parts of Silc Channel Payload interface in the
3211 lib/silccore/silcchannel.[ch]. The encode function now also
3212 encrypts the packet and parse function decrypts it.
3214 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3216 * Fixed a minor formatting bug in the SKE's key material processing.
3217 It actually might have processed the keys wrong way resulting
3220 * Redefined the mandatory HMAC algorithms and added new algorithms.
3221 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3222 and hmac-md5 truncated to 96 bits. The mandatory is now
3223 hmac-sha1-96. Rest are optional (including the one that used
3224 to be mandatory). Rationale for this is that the truncated HMAC
3225 length is sufficient from security point of view and can actually
3226 make the attack against the HMAC harder. Also, the truncated
3227 HMAC causes less overhead to the packets. See the RFC2104 for
3230 * Added new [hmac] configuration section. The SKE used to use
3231 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3232 is of course wrong. The official names that must be proposed in
3233 the SKE are the ones defined in the protocol specification
3234 (hmac-sha1-96 for example). The user can configure any hmac
3235 using any hash function configured in the [hash] section. At
3236 least, the mandatory must be configured.
3238 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3240 * Added HMAC list to the SKE proposal list. It has now both
3241 hash algorithm list and HMAC list. This makes the protocol
3242 incompatible with previous versions. The SKE now seems to work
3243 the way it is supposed to work, for the first time actually.
3245 * Defined plain Hash algorithms to the protocol specification.
3248 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3250 * Implemented support for key agreement packets into the server.
3251 Added functions silc_server_key_agreement and
3252 silc_server_send_key_agreement. Other than these functions,
3253 server has nothing to do with this packet.
3255 * Added support for private message key packets into the server.
3256 Added functions silc_server_private_message_key and
3257 silc_server_send_private_message_key.
3261 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3262 called in the protocol's final callback instead in the END
3263 protocol state. This makes a little more sense and in the same
3264 time in client we can use the same protocol routines for normal
3265 key exchange and to key agreement packet handling as well.
3267 * Added to both client's and server's KE protocol context the
3268 SilcSKEKeyMaterial pointer to save the key material. We will
3269 bring the key material to the protocol's final callback by doing
3270 this. The final callback must free the key material.
3272 * Added SKE's packet_send callback into client's KE protocol
3273 context so that the caller can choose what packet sending function
3274 is used. This way we can use different packet sending when
3275 doing normal SKE when doing key agreement packet handling (in
3276 the key agreement packet handling we do not want to encrypt
3279 * Implemented the responder side of the key agreement routines
3280 in the client. The client can now bind to specified port and
3281 accept incoming key negotiation. The key material is passed
3282 to the application after the protocol is over.
3284 * Implemented the processing of incoming Key Agreement packet
3285 in the client. Added function silc_client_key_agreement to
3288 * Implemented the intiator side of the key agreement routines
3289 in the client. The client can now initiate key agreement with
3290 another remote client. The key material is passed to the
3291 application after the protocol is over.
3293 * Created client_keyagr.c to include all the key agreement
3296 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3297 SILC_TASK_CALLBACK except that it is not static.
3299 * Created client_notify.c and moved the Notify packet handling
3300 from the client.[ch] into that file.
3302 * Created client_prvmsg.c and moved all private message and
3303 private message key routines from the client.[ch] into that file.
3305 * Create client_channel.c and moved all channel message and
3306 channel private key routines from the client.[ch] into that file.
3308 * Changed silc_client_get_client_by_id_resolve to resolve with
3309 WHOIS command instead of IDENTIFY command, in the file
3310 lib/silclient/idlist.c.
3312 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Implemented the SKE's responder side to the Client library.
3316 * When FAILURE is received to the protocol do not trust it
3317 blindly. Register a timeout to wait whether the remote closes
3318 the connection as it should do it, only after that process the
3319 actual failure. This was changed to both client and server.
3321 * Added client_internal.h to include some of the structures
3322 there instead of client.h in lib/silcclient/.
3324 * Added function silc_task_unregister_by_callback to unregister
3325 timeouts by the callback function.
3327 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3329 * Some "Incomplete WHOIS info" errors has been appearing on the
3330 log files. Took away the entry->userinfo check from WHOIS
3331 reply sending. The entry->userinfo is now " " if client did not
3332 provide one. I thought this was fixed earlier but something
3333 is wrong still. Let's see if the error still appears.
3335 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3337 * Fixed a minor bug in the login when the channel key is
3338 re-generated in the server. It used to generate the key in
3339 wrong order and thus caused problems in the channel traffic.
3341 * Fixed a minor bug in channel key distsribution after
3342 KICK command. The key was not sent to the router even though
3345 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3347 * Added silc_ske_process_key_material_data as generic routine
3348 to process any key material as the SILC protocol dictates. The
3349 function is used by the actual SKE library but can be used by
3350 applications as well. This relates to the private message keys
3351 and the channel private keys since they must be processed the
3352 same way the normal SILC session keys. The protocol dictates
3353 this. Affected files: lib/silcske/silcske.[ch].
3355 Added also silc_ske_free_key_material to free the
3356 SilcSKEKeyMaterial structure.
3358 * Defined silc_cipher_set_key function to set the key for
3359 cipher without using the object's method function. The affected
3360 files: lib/silccrypt/silccipher.[ch].
3362 * Implemented silc silc_client_add_private_message_key,
3363 silc_client_add_private_message_key_ske,
3364 silc_client_del_private_message_key,
3365 silc_client_list_private_message_keys and
3366 silc_client_free_private_message_keys functions in the
3369 Added functions silc_client_send_private_message_key to send
3370 the Private Message Key payload and silc_client_private_message_key
3371 to handle incoming Private Message Key payload.
3373 * Added Cipher field to the Private Message Key payload to set
3374 the cipher to be used. If ignored, the default cipher defined
3375 in the SILC protocol (aes-256-cbc) is used.
3377 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3379 * Removed lib/silcclient/ops.h file.
3381 Redefined parts of the SILC Client Library API. Created new
3382 file silcapi.h that deprecates the ops.h file and defines the
3383 published Client Library API. Defined also private message key
3384 API and channel private key API into the file.
3386 This is the file that the application must include from the
3387 SILC Client Library. Other files need not be included by
3388 the application anymore.
3390 * Added new key_agreement client operation callback and also
3391 defined the Key Agreement library API for the application.
3393 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3395 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3396 is used by clients to request key negotiation between another
3397 client in the SILC network. If the negotiation is started it
3398 is performed using the SKE protocol. The result of the
3399 negotiation, the secret key material, can be used for example
3400 as private message key.
3402 Implemented the Key Agreement payload into the files
3403 lib/silccore/silauth.[ch].
3405 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * Redefined ciphers for the SILC protocol. Added some new ciphers
3408 and defined the key lengths for the algorithms. Changed the
3409 code accordingly. The default key length is now 256 bits.
3411 * Fixed SKE key distribution function silc_ske_process_key_material
3412 when the key length is more than 128 bits. The default key
3413 length in SILC is now 256 bits.
3415 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3416 to indicate unsupported algorithm.
3418 * Renamed rijndael.c to aes.c and all functions as well.
3420 * Fixed a long standing channel key setting bug in client library.
3421 Weird that it has never surfaced before.
3423 * Fixed bug in channel deletion. If the entire channel is removed
3424 then it must also delete the references of the channel entry
3425 from the client's channel list as the client's channel entry and
3426 the channel's client entry share same memory.
3428 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Implemented CONNECT and SHUTDOWN commands in the client.
3432 * Implemented CLOSE command to the client.
3434 * Added the function silc_idlist_find_server_by_name into the
3435 files silcd/idlist.[ch].
3437 Added the function silc_idlist_find_server_by_conn into the
3438 files silcd/idlist.[ch].
3440 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3442 * DIE command was renamed to SHUTDOWN. Updated the both code
3445 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3446 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3448 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3451 * Added function silc_server_create_connection function to create
3452 connection to remote router. My server implementation actually
3453 does not allow router to connect to normal server (it expects
3454 that normal server always initiates the connection to the router)
3455 so the CONNECT command is only good for connecting to another
3458 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3460 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3461 or some other client was kicked from the channel.
3463 Implemented the handling of the notify type to both client
3466 Implemented silc_server_send_notify_kicked to send the KICKED
3467 notify. It is used to send it to the server's primary router.
3469 * Implemented the KICK command into server and client.
3471 * Added `query' argument to the silc_idlist_get_client function
3472 to indicate whether to query the client from server or not if
3475 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3476 to indicate that the client is not channel founder.
3480 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3482 * Removed the rng context from SilcPacketContext structure and
3483 changed that the packet routine uses the Global RNG API.
3485 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3487 * Added support for quit message that client can "leave" on the
3488 channel when it quits the SILC. It is ditributed inside the
3489 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3491 Added silc_server_free_client_data that will take the
3492 signoff message as argument.
3494 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3496 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3498 * Updated parts of the protocol specification to keep it up
3501 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3503 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3504 payloads in one packet.
3506 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3507 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3508 use now the new List flag.
3510 * Also deprecated the following packet types: REPLACE_ID,
3511 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3513 * Added list support for Notify packet in server.
3515 * Added silc_server_send_notify_channel_change to send the
3516 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3517 the silc_server_send_replace_id.
3519 * Added silc_server_send_notify_nick_change to send the
3520 NICK_CHANGE notify type. Deprecates the function
3521 silc_server_send_replace_id.
3523 * Added silc_server_send_notify_join to send the JOIN notify type.
3524 Deprecates the function silc_server_send_new_channel_user.
3526 * Added silc_server_send_notify_leave to send LEAVE notify type.
3527 Deprecates the function silc_server_send_remove_channel_user.
3529 * Added silc_server_send_notify_cmode and
3530 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3531 types. Deprecates the silc_server_send_set_mode function.
3533 * Added SERVER_SIGNOFF notify type to indicate that server has
3534 quit. This means that all clients on the channel from that
3535 server will drop. This can be also used when netsplit happens.
3537 Deprecated REMOVE_ID packet type since it is not needed anymore
3540 Added silc_server_send_notify_server_signoff to send the
3541 SERVER_SIGNOFF notify type. Deprecates the function
3542 silc_server_send_remove_id.
3544 Added also silc_server_send_notify_signoff to send the
3545 SIGNOFF notify type.
3547 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3548 SILC protocol from this day on. Changed the protocol
3549 specification as well.
3551 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3552 notify type. It is used between routers to notify about
3553 topic changes on a channel.
3555 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3558 * Partly updated the protocol specification to comply with the
3559 changes now made. It is still though a bit outdated.
3561 * The JOIN notify type now takes one extra argument <Channel ID>.
3562 The packet used to be destined to the channel but now the
3563 JOIN type may be sent as list thus it is impossible to
3564 destine it to any specific channel. By adding this argument
3565 it is again possible.
3567 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3569 * Added CREDITS file. The CHANGES and CREDITS file will appear
3570 in the distribution as well.
3572 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3574 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3575 types in the server's silcd/packet_receive.c.
3577 * Implemented CMODE and CUMODE to work in router environment.
3579 * Fixed minor encoding and decoding buglet from the
3580 lib/silccore/silcmode.c.
3582 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3585 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3587 * Changed all SilcConfigServer* and silc_config_server* to
3588 SilcServerConfig* and silc_server_config*, respectively.
3591 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3593 * Associated the ID (client or server ID) to the Authentication
3594 Payload to avoid any possibility of forging. Updated the
3595 protocol specification and the code accordingly.
3597 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * The RSA key length is now save to the RsaKey context in the
3600 key generation process in lib/silccrypt/rsa.c. The key length
3601 is now used to figure out the maximum size of the block allowed
3602 to be encrypted/signed.
3604 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3605 is equivalent to the silc_mp_mp2bin but does not allocate any
3608 * Changed silc_mp_mp2bin API to take length argument. If it is
3609 non-zero then the buffer is allocated that large. If zero, then
3610 the size is approximated using silc_mp_sizeinbase, which however
3613 * Created Global RNG API which is global RNG that application can
3614 initialize. After initializing, any routine anywhere in the
3615 code (including library) can use RNG without allocating a new
3616 RNG object. This was done to allow this sort of use of the
3617 RNG in code that has no chance to allocate RNG object. All
3618 applications currently allocate this and many routines in the
3619 library use this. Affected file lib/silccrypt/silcrng.[ch].
3621 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3622 it to use the Global RNG API.
3624 * Defined Authentication Payload into protocol specification that
3625 is used during SILC session to authenticate entities. It is
3626 used for example by client to authenticate itself to the server
3627 to obtain server operator privileges.
3629 Implemented this payload into the lib/silccore/silcauth.[ch].
3630 Implemented also routines for public key based authentication
3631 as the new protocol specification dictates.
3633 Moved definitions of different authentication methods from
3634 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3636 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3637 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3638 silc_pkcs_verify_with_hash functions into the file
3639 lib/silccrypt/silcpkcs.[ch].
3641 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3643 * The client entry's userinfo pointer must be always valid.
3644 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3645 will fail since it requires the userinfo. Now, the userinfo
3646 is allocated as "" if actual userinfo does not exist. Actually,
3647 it must exist and it is totally Ok to drop client connections
3648 that does not announce the userinfo. However, we will make
3649 this workaround for now.
3651 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3652 to return the remote port by socket.
3654 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3656 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3657 SILC_SERVER_PENDING_EXEC and added an new macro
3658 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3659 data or when error occurs while processing the pending command.
3661 Added new argument `destructor' into silc_server_command_pending
3662 and to the SilcServerCommandPending object. This destructor is
3663 now called after calling the pending callback or if error occurs
3664 immediately. If error occurs the actual pending callback won't
3665 be called at all - only the destructor. The destructor may be
3666 NULL if destructor is not needed.
3668 All this applies for client library code as well. Similar
3669 changes were made there as well for the pending commands.
3671 In the client, the application must now allocate the
3672 SilcClientCommandContext with the silc_client_command_alloc
3675 * Added reference counter to the SilcServerCommandContext. Added
3676 function silc_server_command_alloc and silc_server_command_dup
3679 Same type of functions added to the client library for the same
3682 * Removed the cmd_ident from IDListData away since it is now
3683 global for all connections. It is the command identifier used
3684 in command sending and with pending commands. The affected file
3687 * Added reference counter to the SilcSocketConnection objecet to
3688 indicate the usage count of the object. The object won't be
3689 freed untill the reference counter hits zero. Currently only
3690 server uses this, and client ignores it. The client must be
3691 set to use this too later. The affected files are
3692 lib/silccore/silcsockconn.[ch]. Added also the function
3693 silc_socket_dup to increase the reference counter.
3695 This was mainly added because it is possible that the socket
3696 is removed underneath of pending command or other async
3697 operation. Now it won't be free'd and proper DISCONNECTING
3698 flags, etc. can be set to avoid sending data to connection that
3699 is not valid anymore.
3701 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3702 the connection. After that it sets SILC_SET_DISCONNECTED.
3703 It is, however, possible that the socket data is not still freed.
3704 The silc_server_packet_process now checks that data is not
3705 read or written to connection that is DISCONNECTED. The socket
3706 get's freed when the reference counter hits zero.
3708 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3710 * Changed the client operation API: channel_message operation's
3711 `sender' is now the client entry of the sender, not the nickname
3712 and the `channel' is the channel entry, not the channel name.
3714 In the private_message operation the `sender' is now also the
3715 client entry of the sender not the nickname.
3717 Affected file is lib/silcclient/ops.h and all applications
3718 using the client operations.
3720 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3722 * Moved the calling of ops->connect() from connect_to_server_final
3723 into receive_new_id functin since that is the point when the
3724 client is actually allowed to send traffic to network. The
3725 affected file is lib/silcclient/client.c.
3727 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3729 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3730 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3731 (if needs broadcasting) instead of broadcasting the packets one
3732 by one which would make a burst in the network traffic.
3734 * Added `broadcast' argument to the functions in silcd/server.[ch]
3735 silc_server_create_new_channel[_with_id] to indicate whether
3736 to send New Channel packet to primary router.
3738 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3740 * Added new function into the silcd/server.[ch] files:
3741 silc_server_create_new_channel_with_id to create new channel with
3742 already existing Channel ID.
3744 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3745 lib/silccore/silcpacket.h. This packet is used t send list of
3746 Set Mode payloads inside one packet. Server uses this to set
3747 the modes for the channels and clients on those channels, that it
3748 announced to the router when it connected to it. The protocol
3749 specification has been updated accordingly.
3751 * The silc_server_new_channel did not handle the packet coming
3752 from normal server as it normally does not send that. However,
3753 when it announces its channels it does send it. Implemented
3754 the support for that.
3756 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3757 into the file lib/silccore/id.h.
3759 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3761 * Fixed memory leaks in the functions silc_idlist_del_client,
3762 silc_idlist_del_channel and silc_idlist_del_server in the file
3763 silcd/idlist.c. All of those leaked like a sieve.
3765 * Fixed some small memory leaks in the client's function
3766 silc_client_notify_by_server.
3768 * Added functions into silcd/server.c: silc_server_announce_clients,
3769 silc_server_announce_channels and silc_server_announce_server.
3770 These functions are used by normal and router server to announce
3771 to its primary router about clients, channels and servers (when
3772 router) that we own. This is done after we've connected to the
3775 These functions effectively implements the following packet types:
3776 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3777 and SILC_PACKET_NEW_ID_LIST.
3779 * Added new functions into the silcd/packet_receive.[ch]:
3780 silc_server_new_id_list, silc_server_new_channel_list and
3781 silc_server_new_channel_user_list to handle the incoming
3782 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3784 * Added support of changing Channel ID in the function
3785 silc_server_replace_id. If the server that announces a channel
3786 to the router already exists in the router (with same name but
3787 with different Channel ID), router is responsible to send
3788 Replace ID packet to the server and force the server to change
3789 the Channel ID to the one router has.
3791 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3792 client that the Channel ID has been changed by the router. The
3793 normal server sends this to the client. Client must start using
3794 the new Channel ID as the channel's ID.
3796 Implemented handling of this new type into lib/silcclient/client.c
3797 into the function silc_client_notify_by_server.
3799 * Added new function silc_idlist_replace_channel_id into the files
3800 silcd/idlist.[ch] to replace the Channel ID.
3802 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Call silc_server_command_identify_check always when processing
3805 the IDENTIFY command in silcd/command.c
3807 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3809 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3810 send keepalive packets. The packet can be sent by clients,
3811 servers and routers.
3813 Added function silc_socket_set_heartbeat into the file
3814 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3815 If not set, the heartbeat is not performed. The actual
3816 heartbeat is implemented in the low level socket connection
3817 library. However, application is responsible of actually
3820 Added silc_server_send_heartbeat to send the actual heartbeat
3821 packet into silcd/packet_send.[ch]. Server now performs
3822 keepalive with all connections.
3824 * Added silc_task_get_first function into lib/silcutil/silctask.c
3825 to return the timeout task with shortest timeout. There was a bug
3826 in task unregistration that caused problems. TODO has been
3827 updated to include that task system must be rewritten.
3829 * The client library will now resolve the client information when
3830 receiving JOIN notify from server for client that we know but
3831 have incomplete information.
3833 * Rewrote parts of silc_server_remove_from_channels and
3834 silc_server_remove_from_one_channel as they did not remove the
3835 channel in some circumstances even though they should've.
3837 * Encryption problem encountered in server:
3839 The LEAVE command used to send the Channel Key packet to the
3840 router immediately after generating it. However, the code
3841 had earlier sent Remove Channel user packet but not immediately,
3842 ie. it was put to queue. The order of packets in the router
3843 was that Channel Key packet was first and Remove Channel User
3844 packet was second, even though they were encrypted in the
3845 reverse order. For this reason, MAC check failed. Now, this
3846 is fixed by not sending the Channel Key packet immediately but
3847 putting it to queue. However, this is more fundamental problem:
3848 packets that are in queue should actually not be encrypted
3849 because packets that are sent immediately gets encrypted
3850 actually with wrong IV (and thus MAC check fails). So, packets
3851 that are in queue should be encrypted when they are sent to
3852 the wire and not when they put to the queue.
3854 However, the problem is that the current system has not been
3855 designed to work that way. Instead, the packet is encrypted
3856 as soon as possible and left to the queue. The queue is then
3857 just purged into wire. There won't be any fixes for this
3858 any time soon. So, the current semantic for packet sending
3861 o If you send packet to remote host and do not force the send
3862 (the packet will be in queue) then all subsequent packets to the
3863 same remote host must also be put to the queue. Only after the
3864 queue has been purged is it safe again to force the packet
3867 o If you send all packets immediately then it safe to send
3868 any of subsequent packets through the queue, however, after
3869 the first packet is put to queue then any subsequent packets
3870 must also be put to the queue.
3872 Follow these rules and everything works fine.
3874 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3876 * Added new function silc_server_remove_clients_by_server to
3877 remove all client entries from ID list when the server connection
3878 is lost. In this case it is also important to invalidate all
3879 client entires as they hold the invalid server entry. This
3880 fixes fatal bug when server has lost connection and will reconnect
3883 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3885 * Made some sanity checks to silc_server_daemonise like to check
3886 whether the requested user and group actually exists.
3888 * Added sanity check to SKE's silc_ske_responder_finish to check
3889 that the public and private key actually is valid.
3891 * Invalidate the client's nickname when receiving Replace ID
3892 packet and the Client ID is being replaced. This means that the
3893 server will query the nickname if someone needs it (client)
3896 * Sort the ID Cache in client library when the ID Cache data
3897 has changed (needs sorting).
3899 * Do not allow for SILC client to create several connections to
3900 several servers. The client does not support windows right now
3901 and generating multiple connections causes weird behaviour.
3903 Irssi-silc client does support windows and can handle several
3904 connections without problems, see: www.irssi.org and SILC plugin.
3906 * Fixed some places where client was added to the IDList. The
3907 rule of thumb is following (in order to get everything right):
3908 If the client is directly connected local client then the
3909 `connection' argument must be set and `router' argument must be
3910 NULL to silc_idlist_add_client function. If the client is not
3911 directly connected client then the `router' argument must
3912 bet set and the `connection' argument must be NULL to the
3913 silc_idlist_add_client function.
3915 * The funtion silc_server_packet_send_local_channel actually did
3916 not check whether the client was locally connected or not. It
3917 does that now. Fixed a bug related to LEAVE command.
3919 * Fixed Remove Channel User payload parsing bug in server's
3920 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3922 * The server's silc_server_save_channel_key now checks also the
3923 global ID list for the channel as it might not be in the local
3924 list. Fixed a bug related to LEAVE command.
3926 * Is this the end of the [<unknown>] buglet that has been lurking
3927 around for a long time? A little for loop fix in server's
3928 silc_server_command_whois_parse that is used by both IDENTIFY
3929 and WHOIS command. At least, this was a clear bug and a cause
3930 of one type of [<unknown>] buglet.
3932 * WHOIS and IDENTIFY commands call the function
3933 silc_server_command_[whois/identify]_check function even if
3934 we are not router server.
3936 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3938 * Added --with-gmp configuration option. If set the GMP
3939 is always compiled in the SILC source tree. If not set then
3940 it is checked whether the system has the GMP3 installed. If
3941 it has then the GMP won't be compiled (the system's headers
3942 and library is used), if it doesn't have it then the GMP is
3943 compiled in the SILC source tree.
3945 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3947 * Changed RSA private exponent generation to what PKCS #1
3948 suggests. We try to find the smallest possible d by doing
3949 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3950 not security fix but optimization.
3952 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3954 * Added new config entry [Identity] to fork the server and run
3955 it as specific user and group. A patch from Bostik.
3957 * Imported Dotconf configuration library into lib/dotconf.
3958 This will be used to create the SILC configuration files later.
3959 It will appear in the distsribution after this commit.
3961 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3963 * A big code auditing weekend happening. Auditing code for
3964 obvious mistakes, bugs and errors. Also, removing any code
3967 Removed files for being obsolete:
3969 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3970 inline in the file lib/silcutil/silcbuffer.h)
3972 o lib/silcutil/silcbufutil.c (the header has inline versions)
3974 Changed code to fix possible error conditions:
3976 o The buffer formatting routines now check that the destination
3977 buffer really has enough space to add the data. This applies for
3978 both buffer formatting and unformatting
3979 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3980 unformatting was changed to accomodate following rules:
3981 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3982 sent to the function while XXX_*STRING will not allocate or copy
3983 the data into the buffer. Instead it sets the pointer from the
3984 buffer into the pointer sent as argument (XXX_*STRING used to
3985 require that the pointer must be allocated already). This change
3986 makes this whole thing a bit more consistent and more optimized
3987 (note that the data returned in the unformatting with XXX_*STRING
3988 must not be freed now). The routines return now -1 on error.
3990 o Tried to find all code that use buffer_format and buffer_unformat
3991 and added return value checking to prevent formatting and
3992 especially unformatting errors and possible subsequent fatal
3995 o Changed ske->x and ske->KEY to mallocated pointers in
3996 lib/silcske/silcske.h. Fixed possible data and memory leak.
3998 o Added return value checking to all *_parse* functions. Fixed
3999 many memory leaks as well.
4001 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
4002 so that buffer overflows would not happen. All code now also
4003 checks the return value as it can fail.
4005 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4007 * Added reconnection support to server if the normal server looses
4008 its connection to the router (for example if router is rebooted).
4009 The server performs normal reconnection strategy implemented
4010 to the server. Affected file silcd/server.c.
4012 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4014 * Added new packet type SILC_PACKET_SET_MODE that is used to
4015 distribute the information about changed modes (for clients,
4016 channels and clients channel modes) to all routers in the
4017 network. Updated the protocol specification accordingly.
4019 Added functions into silcd/packet_send.c and
4020 silcd/packet_receive.c: silc_server_send_set_mode,
4021 silc_server_set_mode.
4023 Added new files silcmode.[ch] into lib/silccore that implements
4024 the encoding and decoding of Set Mode Payload. Added new type
4025 SilcSetModePayload. Moved the definitions of different modes
4026 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4028 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4030 * Oops, a little mistake in server's connection authentication
4031 protocol. The protocol is not ended with FAILURE but with
4032 SUCCESS if the authentication is Ok. :) Affected file is
4035 * Implemented NICK_CHANGE notify handling in server in the file
4036 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4037 the local clients on the channel. After the changing nickname
4038 in router environment snhould work and the [<unknown>] nickname
4039 should appear no more.
4041 The silc_server_replace_id function that receives the Replace ID
4042 payload now sends the NICK_CHANGE notify type also in the file
4043 silcd/packet_receive.c
4045 * Changed WHOIS and IDENTIFY command to support the maximum amount
4046 of arguments defined in protocol specs (3328 arguments). This
4047 fixed a bug that caused problems when there were more than three
4050 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4052 * Added extra parameter, command identifier, to the
4053 silc_client_send_command so that explicit command identifier
4056 Changed that ID list routines uses specific command identifier
4057 when sending WHOIS/IDENTIFY requests to the server so that they
4058 can be identified when the reply comes back.
4060 Affected files lib/silcclient/command.[ch],
4061 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4063 * Added `sender' argument to silc_server_packet_send_to_channel
4064 to indicaet the sender who originally sent the packet to us
4065 that we are now re-sending. Ignored if NULL. Affected file
4066 silcd/packet_send.[ch].
4068 * Added some server statistics support in silcd/server_internal.h
4069 SilcServerStatistics structure and around the server code. Also
4070 send some nice statistics information when client is connecting
4073 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4075 * Fixed channel ID decoding in server's JOIN command reply in
4076 silcd/command_reply.c
4078 * Fixed braodcasting of replace ID payload to not to send it if
4079 we are standalone server in silcd/packet_receive.c.
4081 * Fixed all channel message sending routines to not to send
4082 packets to clients that has router set, since they are routed
4083 separately in the same function earlier. Affects file
4084 silcd/packet_send.c and all channel packet sending functions.
4086 * In USERS reply, res_argv[i] are not allocated, the table
4087 is allocated. Thus changed that free the table, not its
4090 * In server's whois_check and identify_check if the client is
4091 locally connected do not send any WHOIS commands - they are not
4094 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4096 * Fixed some minor bugs in client when sending WHOIS command. The
4097 arguments was in wrong order.
4099 * Removed statis function add_to_channel from server in
4100 silcd/command.c that was previously used with the joining but
4103 * Tested USERS command in router environment successfully with two
4104 routers, two servers and two clients.
4106 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4108 * Reorganized the USERS command and command reply in client library
4109 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4110 When the command is given by user we register a pending command
4111 callback that will reprocess the command after the reply has been
4112 received from the server. When reprocessing the packet we then
4113 display the information. Thus, the USERS information is displayed
4114 now in the command callback instead of in the command reply
4115 callback. The processing of the command is same as previously
4116 when server has sent the command reply in the JOINing process.
4118 * Added to USERS command in silcd/command_reply.c to join the client,
4119 we didn't use to know about, to the channel after we've created
4120 a client entry for it. Also, for clienet we did know already still
4121 check whether it is on the channel or not and add it if not.
4123 * Removed silc_server_command_join_notify as the function and its
4126 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4128 * Changed the client's pending command handling to the same as the
4129 server's pending command handling. It is also now possible to
4130 execute command reply functions from other command reply
4131 function as the function callbacks for commands and command
4132 replies are one and same. The pending commands are not static
4133 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4134 in client connection context. Thus, pending commands are server
4135 connection specific as it is convenient.
4137 Changed the function silc_client_command_pending and
4138 silc_client_command_pending_del and added new function
4139 silc_client_command_pending_check. Removed the
4140 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4143 * Added cmd_ident, current command identifier, to the client
4144 connection context in lib/silcclient/client.h to keep track on
4145 command identifiers used in command sending. Client's command reply
4146 function handling now supports the mandatory command identifiers.
4148 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4149 funtions in client to fully support pending command callbacks.
4151 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4152 as one of the arguments to the application in the command reply
4155 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4156 before first releasing SILC but came back. Now it is removed again
4157 and should come back nomore. The FORWARDED flag was used only
4158 by the JOINing procedure by forwarding the command packet to router.
4159 Now, the JOINing procedure has been changed to more generic (due
4160 to various router environment issues) and FORWARDED is not needed
4161 anymore for anything. The protocol specification is yet to be
4164 Now, removed silc_server_packet_forward from server and the flag
4165 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4167 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4169 * Renamed NAMES command to USERS command. The NAMES was named that
4170 due to historical reasons. Now it is renamed. Also, rewrote
4171 parts of the USERS command. The nickname list is not sent anymore
4172 by the server. Only Client ID and mode lists are sent in the USERS
4173 command. Changed this also to the protocol specification.
4175 The client now resolves the names and stuff after it receives
4176 the USERS list from the server when joining to the channel.
4178 * WHOIS and IDENTIFY commands has been changed to support multiple
4179 Client ID's per command. One can now search for multiple users
4180 in the network by sending only one WHOIS or IDENTIFY command.
4181 Changed the code and the protocol specifications.
4183 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4184 uses silc_server_command_whois_parse to parse the request. */
4186 * If normal server, do not parse the WHOIS and IDENTIFY requests
4187 before sending it to the router. Saves some time.
4189 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4191 * Fixed JOIN command on client library. Wrong number of arguments
4192 used to crash the client.
4194 * Added silc_server_channel_has_global function to check whether
4195 channel has global users or not.
4197 * Added silc_server_channel_has_local function to check whether channel
4198 has locally connected clients on the channel.
4200 * The silc_server_remove_from_one_channel now checks whether the
4201 channel has global users or not after given client was removed from
4202 the channel. It also checks whether the channel has local clients
4203 on the channel anymore. If it does not have then the channel entry
4204 is removed as it is not needed anymore.
4206 * The silc_server_notify now checks on JOIN notify whether the joining
4207 client is one of locally connected or global. If it is global then
4208 the channel has now global users on the channel and that is marked
4209 to the channel entry. Also, it now saves the global client to
4210 global list who is joining and JOINs it to the channel. This is
4211 for normal server, that is.
4213 Changed silc_server_send_notify_on_channel,
4214 silc_server_packet_relay_to_channel and
4215 silc_server_packet_send_to_channel check if we are normal server
4216 and client has router set (ie. global client) do not send the
4217 message to that client, as it is already routed to our router.
4219 * Implemented LEAVE notify type handling in silc_server_notify
4222 * Tested LEAVE command in router environment successfully. Tested
4223 with two routers, two servers and two clients.
4227 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4229 * Implemented SIGNOFF notify type handling in silc_server_notify
4232 * silc_server_remove_id now removes the client entry from all channels
4233 it has joined and thusly sends SIGNOFF notify type.
4235 * Rewrote the NAMES list generation in server by removing two excess
4236 loops. The lists are created now inside one loop.
4238 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4240 * silc_server_remove_channel_user checks now also global list
4241 for channel and client.
4243 * silc_server_new_channel_user checks now both local and global
4244 list for channel and client. Fixed a bug in client id decoding.
4245 Used to decode wrong buffer.
4247 * silc_server_channel_message checks now both local and global
4248 list for channel entry.
4250 * Tested channel joining (hence JOIN) in router environment
4251 successfully. Tested with two routers, two servers and two
4254 * Tested channel message sending in router environment successfully.
4256 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Added silc_server_save_channel_key into server.[ch] to save the
4259 received channel key in Channel Key payload processing. It is
4260 also used in JOIN command reply handling.
4262 Equivalent function silc_client_save_channel_key added into
4263 client.[ch] into client library.
4265 * Changed JOIN command reply to send information whether the channel
4266 was created or not (is existing already) and the channel key
4267 payload. Changed protocol specs accordingly.
4269 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4270 the request was sent by ID and not by nickname. Crashed on
4273 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4275 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4276 now correctly save the received data.
4278 * silc_server_free_sock_user_data now notifies routers in the
4279 network about entities leaving the network.
4281 At the same time implemented functions silc_server_remove_id
4282 and silc_server_send_remove_id to receive and send REMOVE_ID
4283 packets. The packet is used to notify routers in the network
4284 about leaving entities. The ID removed will become invalid in
4287 * Added function silc_idlist_del_server into server. Removes and
4288 free's server entry from ID list.
4290 * silc_server_private_message function now checks, if we are router,
4291 that the destination ID really is valid ID, naturally.
4293 * In router when NEW_ID packet is received (for new client) the
4294 hash of the Client ID is saved in the ID Cache but the
4295 client->nickname is set to NULL, instead of putting the hash
4298 IDENTIFY command now also checks that client->nickname must be
4299 valid. If it is not if will request the data from the server who
4300 owns the client. Added new function
4301 silc_server_command_identify_check.
4303 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4304 to set the command to already allocated Command Payload.
4306 * Tested private message sending in router environment with two
4307 routers, two servers and two clients. Fixed minor bugs and now
4310 * Fixed segfault from client's NAMES command. Used to crash if
4313 * Forwarded packets must not be routed even if it is not destined
4314 to the receiver. Changed server code comply with this.
4316 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4318 * Added `require_reverse_mapping' boolean value to ServerParams
4319 structure. If TRUE (not default) the server will require that
4320 the connecting host has fully qualified domain name.
4322 If the reverse mapping is not required and hostname could not be
4323 found the IP address is used as hostname.
4325 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4327 * Implemented version string checking to both client and server.
4328 The check is incomplete currently due to the abnormal version
4329 strings used in development version of SILC.
4331 * Changed all command functions in server to use the new
4334 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4336 * Changed char *data to unsigned char *data in ID Cache system to
4337 support binary data as ID Cache data. Changed code to support
4338 binary data in lib/silccore/idcache.c.
4340 * Renamed silc_server_packet_relay_command_reply to
4341 silc_server_command_reply as it is normal packet receiving
4342 function. Rewrote the function to accept command replys for
4343 servers and not only for clients.
4345 * Mark remote router always as registered server if we are connecting
4346 to it. Otherwise, commands sent by the router to us are ignored.
4348 * All ID List find routines now returns the ID Cache Entry pointer
4349 as well if requested.
4351 * WHOIS command works now in router environment, tested with two
4352 routers, two servers and two clients.
4354 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4355 in router environment (as it is almost equivalent to WHOIS) but
4356 hasn't been tested thoroughly. Added new functions:
4358 silc_server_command_identify_parse
4359 silc_server_command_identify_send_reply
4360 silc_server_command_identify_from_client
4361 silc_server_command_identify_from_server
4363 * Disabled route cache adding because adding two different ID's with
4364 same IP replaces the old cache entry thus giving wrong route.
4365 The entry->router->connection is always the fastest route anyway
4366 so route cache may not be needed. Of course, new routes maybe
4367 established after receiving the ID when the entry->router->connection
4368 might not be anymore the most optimal.
4370 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4372 * Add route cache for received ID for fast routing.
4374 * Added silc_server_packet_route to route received packet on router
4375 that is not destined to us.
4377 * Renamed silc_server_get_route to silc_server_route_get.
4379 * Added id_string and id_string_len fields into SilcServer to
4380 include encoded ServerID for fast comparing without excess
4381 encoding of the ID's.
4383 * Cleaned up WHOIS command on server side. Added following static
4386 silc_server_command_whois_parse
4387 silc_server_command_whois_check
4388 silc_server_command_whois_send_reply
4389 silc_server_command_whois_from_client
4390 silc_server_command_whois_from_server
4392 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4393 arguments in command replies. All command functions should be
4394 updated to use this macro.
4396 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4398 * Minor typo fixes on command reply handling on server.
4400 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4402 * Added silc_server_command_add_to_channel internal routine to add
4403 the client to the channel after router has created the channel and
4404 sent command reply to the server.
4406 * Added generic silc_server_send_command to send any command from
4409 * Use static buffer with ID rendering instead of duplicating data.
4411 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4413 * Fixed a channel user mode bug when joining to a channel server gave
4414 everybody channel founder rights, oops.
4416 * We mark ourselves as the router of the incoming server connection
4417 if we are router ourselves. This way we can check in some packet
4418 sending functions whether it is locally connected server. For
4419 incoming router connections we put NULL.
4421 * For router sending packets locally means now always sending the
4422 packet cell wide; to local clients and local servers. For normal
4423 server sending packet locally means sending it to only local
4426 * Fixed the JOIN command to really work in router environment. If the
4427 channel is created it is always created by the router. Router is
4428 also responsible of making the initial joining to the channel,
4429 sending JOIN notify to the sending server and distributing
4430 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4431 does not exist server doesn't do anything else but forward the
4432 command to the router which performs everything.
4434 * Added silc_server_send_channel_key function to send the Channel Key
4437 * Added silc_server_create_channel_key to create new channel key. The
4438 channel key is now re-generated everytime someone joins or leaves
4439 a channel, as protocol dictates. Note: channel->key_len is the
4442 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4444 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4445 packet_receive.[ch] to separate packet sending and receiving
4446 routines. The server.[ch] now includes everything else including
4447 actual packet processing (writing and reading data) and other
4450 Renamed silc_server_private_message_send_internal to
4451 silc_server_send_private_message. The routine is still though
4452 used only to relay private messages as server does not send
4453 private messages itself.
4455 Renamed silc_server_new_channel to silc_server_create_new_channel
4456 and added new function sicl_server_new_channel that handles the
4457 incoming New Channel packet. Added also new sending function
4458 silc_server_send_new_channel to send New Channel Payload.
4460 * Added new function silc_server_notify to process incoming notify
4461 packet to the server/router. Server may then relay the notify
4462 to clients if needed.
4464 * Added new function silc_server_new_channel_user to process incoming
4465 New Channel User packet. Router will redistribute the packet and
4466 send JOIN notify to its local clients and locally connected servers
4467 if needed. Normal server will send JOIN notify to its local client
4468 on same channel when received this packet. Added also corresponding
4469 sending function silc_server_send_new_channel_user to sent the
4472 * Added boolean route argument to send_notif_to_channel and
4473 packet_send_to_channel functions to attempt to route the packet
4474 if it is TRUE and send only locally if it is FALSE.
4476 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * silc_server_replace_id now broadcasts the received replace ID
4479 packet if it is not broadcast packet already. The router must
4480 broadcast to inform other routers about changed ID.
4482 * Added backpointer to server's router into SilcServer context in
4483 silcd/server_internal.h.
4485 * Fixed silc_server_packet_broadcast to send correct broadcast
4488 * The channel key is now distributed to the local client as soon
4489 as it is received from the router (in router environment) so that
4490 no other packet may be sent for the channel until client has
4493 * silc_server_remove_channel_user now broadcasts the received
4494 Remove Channel User packet if it is not broadcast packet already.
4495 The router must broadcast to inform other routers about removed
4498 * Added users field into SilcPacketContext that is a reference count
4499 of the context. One can increase the reference count by calling
4500 silc_packet_context_dup which is now changed to just increase the
4501 reference count instead of duplicating the data. The reference
4502 count is decresed by calling silc_packet_context_free that will
4503 free the data after the reference count hits zero.
4505 For now on the packet context and everything allocated into it
4506 (including the raw packet from network) must be freed by calling
4507 the new silc_packet_context_free function. Added also new function
4508 silc_packet_context_alloc that must be used now to allocate the
4509 context. This also means that if a routine is asynchronous from
4510 silc_[client/server]_packet_parse_type the packet context must
4511 be duplicated by calling silc_packet_context_dup. Otherwise it
4512 gets free'd after silc_[client/server]_packet_parse_type returns.
4513 Also, one must remember that if packet is duplicated then its
4514 reference count must be decresed by calling the free function as
4515 many times as it was duplicated.
4517 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4518 from both client and server.
4520 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4522 * Made joining to a channel working in router environment.
4524 * Cleaned up JOIN command on server side and create function
4525 silc_server_command_join_channel internal routine to make the
4528 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4530 * Changed silc_command_pending list to SilcDList. Also, added
4531 `ident' field to SilcServerCommandPending structure to identify
4532 the reply and to call correct callback.
4534 Added silc_server_command_pending_check function to replace the
4535 corresnponding macro. The silc_command_pending list is not
4538 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4539 to set identifier to previously allocated Command Payload. It
4540 is used to set identifier for command when resending Command
4543 * Added silc_command_payload_encode_payload to encode Command
4544 Payload buffer from SilcCommandPayload structure.
4546 * Added silc_argument_payload_encode_payload to encode Argument
4547 payload buffer from SilcArgumentPayload structure.
4549 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4551 * Changed WHOIS command to support router connection on server side.
4552 The whois request is always sent to router unless the server is
4553 standalone server. After server has received the reply from the
4554 router will it send the reply to the client.
4556 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4557 broadcast received broadcast packet. The function is used only
4558 by router. The broadcast packet is always sent to the router's
4561 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4562 render given ID to printable string, for log files for example.
4564 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4566 * Made basic router to router connections working. At least they
4567 can now connect to each other but nothing really works the way
4568 they are supposed - yet.
4570 * Added new initiator token to RouterConnection configuration
4571 file in silcd/serverconfig.[ch]. It is used to tell whether we
4572 are the initiator to the remote router or whether we'll expect
4573 the other end to connect.
4575 * Moved registering of listener task to silc_server_init, hence
4576 the server starts listenning as soon as it is run, even if it
4577 does not have connections to other routers. Let's see how well
4580 * Changed default connection retry timeouts for more suitable in
4583 * Removed cipher and such arguments from silc_idlist_add_client
4584 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4585 Added new function silc_idlist_add_data to add the keys and stuff
4588 * Added SilcIDListData structure and added it to SilcClientEntry
4589 and SilcServerEntry as their first field in the structure. This
4590 way we can explicitly cast the ID entries to the SilcIDListData
4591 structure and get common data for the entries. In past, we had
4592 to first check what type of connection it is and then cast it to
4593 correct ID entry type. Now, we can directly cast the opaque
4594 pointer to the SilcIDListData (no matter what ID entry it actually
4595 is) and get the data needed.
4597 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4599 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4600 in some circumstances even if threre were timeout tasks, though not
4601 IO tasks, but tasks anyway. Now fixed.
4603 * Defined SilcServerConnection structure to hold connection specific
4604 stuff about directly connected servers and routers. The definition
4605 is currently in silcd/server_internal.h. I thought about having
4606 a bit more important role fro this struct but for now it is used
4607 only when connecting to other server (or router actually).
4609 * Added connecting retry support in server when connecting to
4610 router(s). The retry feature implement exponential backoff
4611 algorithm. Also, added SilcServerParams structure to hold default
4612 parameters for server. For now, it include these retry settings
4613 and are hard coded. After server is moded to be as Silc Server
4614 Library this structure will be more important.
4616 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Changed client librarys channel->clients table to SilcList and
4619 changed code accordingly.
4621 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4623 * Changed client's channel table to SilcList and changed code
4624 accordingly. Also changed SilcChannelClientEntry to include back-
4625 pointer to the channel so that client entry can use that structure
4626 as list as well and we have fast cross-reference to the channel.
4627 This change dramatically decreased the complexity of channel
4628 handling with client entry and vice versa (removed one extra
4629 loop when searching for channel entry from many functions).
4631 * Changed server->sim from table to SilcDList and changed code
4634 * NAMES command can now be used from user interface. It will show
4635 the user list on the channel, neatly.
4637 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4638 Code now saves realname of the user if it becomes available.
4640 * Renamed configure.in to configure.in.pre and made ./prepare
4641 script to automatically add correct version string to
4642 configure.in which it creates from configure.in.pre.
4644 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4646 * NAMES command reply now shows users mode with the nickname when
4649 * Moved silc_client_ch[u]mode[_char] functions from
4650 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4651 place sucks, they are utility functions and should be in some
4654 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4656 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4659 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * Added TRQ (efficient deque and list library) into lib/trq. This is
4664 a very good list library that is currently used in the SILC. Defined
4665 SilcList API over the library because I didn't like the API very
4666 much. See lib/trq/silclist.h for the API and examples of how to
4667 use the API. Fixed various places in the code to use the new
4668 SilcList API. The SilcList is meant for lists that has a structure
4669 already defined as a list. It is not suitable to add just some
4670 context to the list (in TRQ, the context is the list actually).
4672 So, I defined SilcDList that can be used for the purpose where
4673 predefined list structure does not exit. This can be used as
4674 such list. Now some context just can be added to the SilcDList.
4675 Currently this list is not used in the SILC just yet, though there
4676 are a lot places where this can replace dynamically allocated
4677 tables and I will fix these places, later, to use SilcDList.
4678 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4679 and use TRQ internally).
4681 Also fixed some annoying warning messages that the original TRQ
4682 code generated. Also minor changes to TRQ's Makefile.in.
4684 * Added support for querying by Client ID to both WHOIS and
4685 IDENTIFY commands into server, as required by the protocol.
4687 * Removed method function pointers from SilcBuffer structure. They
4688 weren't used to anything and just increased the context size for
4689 no good reason. This change also made silc_buffer_alloc and
4690 silc_buffer_free functions inline functions.
4692 * Disabled command flooding detection support until it's fixed so
4693 that it accepts commands in but does not execute them more than once
4696 * Added silc_net_localhost(), to return local hostname, into
4697 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4698 that must be initialized before calling silc_client_init.
4700 * Added new function: silc_server_send_notify_on_channels to send
4701 notify messages to all channels client has joined. It is assured
4702 that the message is sent only once per client.
4704 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4705 lib/silcutil/silcutil.[ch] as silc_format function. The new
4706 function is generic and is used by server as well, not only by
4707 the logging routines.
4709 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4710 the provided version string was not acceptable. Added new function:
4711 silc_ske_check_version into lib/silcske/silcske.h. The function
4712 must be implemented by the application (client or server) and it
4713 does not reside in the SKE library. The function checks the version
4714 string remote end sent.
4716 * Added back pointers (to opaque context and to SilcSocketConnection)
4717 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4719 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4720 duplicate packet context structure.
4722 * Changed `notify' client operation to send same arguments as client
4723 receives from server except for ID's. ID's are mapped to correct
4724 ID entry and that is returned. Also, if channel entry is not sent
4725 by server but the notify is for channel the channel entry is sent
4726 to application (otherwise application doesn't know that it is for
4727 channel (library gets it from packet's Destination ID)).
4729 * Added silc_client_remove_from_channels into client library to
4730 remove a client from all channels it has joined to. Used when
4731 received SIGNOFF notify from server. Added also new function
4732 silc_client_replace_from_channels to replace old ID entry with
4733 new ID entry on all channels. Used when received NICK_CHANGE
4736 * Fixed ID Cache list handling in silc_idlist_get_client in
4737 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4738 to get (or query) client by ID.
4740 * Updated TODO list.
4742 * Added connection authentication status message defined by the
4743 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4744 support for these into the code in client and server side.
4746 * Added generic function silc_client_send_command to send any command
4747 with variable argument list. Application should use this function
4748 to send commands if the command functions provided by the library
4749 does not suite for the application's user interface needs.
4751 * Added new `failure' client operation. Application is notified about
4752 received failure packet if client is executing a protocol. In this
4753 case the protocol's execution has failed.
4755 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4756 is required by the protocol.
4758 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4759 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4762 * Added status flag to SilcSKE object to indicate realtime status
4763 of the SKE protocol.
4765 * Application receives now exactly same command reply arguments as
4766 the library receives from server. However, if ID is received the
4767 corresponding ID entry is returned to the application (eg. Client
4768 ID is mapped to correct SilcClientEntry entry and that is returned).
4769 Changed command_reply client operation due to this change.
4771 * Changed all ID's in commands and in command replys as ID Payloads.
4772 Change affected both client and server side codes.
4774 All ID's sent in SILC network (with execption of ID's in SILC
4775 Packet header) are sent in ID Payload to support variable length
4778 * Server now notifies nick changes and notifies all clients on
4779 the channels about the new nickname (about the new Client ID,
4782 * Implemented CMODE command to change channel modes. Supports all
4783 channel modes defined by the protocol specs except ban and invite
4784 lists. (Also, private channel key mode is supported but support for
4785 setting private channel key in client is missing, thus, this mode
4786 has no effect on client side (except that server requires that the
4787 client uses private channel key and normal channel traffic does not
4790 Also, invite mode works per se, but INVITE command does not work
4791 yet correctly, so you can set channel as invite only channel but
4792 inviting clients to the channel does not work (it is yet to be
4793 thought what's the best way to do it).
4795 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4796 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4797 Implemented CUMODE command to change user's mode on the channel.
4798 Supports all modes defined by the protocol specs.
4800 * Added NAMES command reply to return users modes on the channel.
4802 * Removed unnecessary and slow ciphers from lib/silccrypt.
4804 * Set SO_KEEPALIVE option to connection sockets by default.
4806 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4808 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4809 redefined the Notify Payload into protocol specs.
4811 * Added silc_id_payload_parse_id to get ID directly from raw
4814 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4816 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4817 accept searching by Client ID as well.
4819 * Added support for LEAVE and SIGNOFF notify types in client library.
4821 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4822 to parse ID Payload from raw data.
4824 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4826 * Added flags parameter into silc_ske_assemble_security_properties
4827 function in lib/silcske/silcske.[ch].
4829 * Changed notify client operation to fit better for notify messages
4830 sent by server. The notify payload received from server is now
4831 passed to the application (after parsing it to SilcNotifyPayload).
4832 It is application's responsibility to retrieve the arguments
4833 from the payload and show the message the way it wants. The message
4834 sent by server is implementation specific.
4836 * Changed public keys to comply with the protocol specification.
4837 Old public keys are not supported anymore and are not compatible.
4839 * Removed nickname from Channel Payload as the latest draft removed
4840 it. The client must resolve the nickname from the NAMES command
4841 reply received when it joined the channel.
4843 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4845 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4847 * Fixed some errors in protocol specification drafts.
4849 * Created lib/silccore/silcnotify.c to implement Notify Payload
4850 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4851 generic payloads described by protocol specifications. The file
4852 includes implementations for ID Payload and Argument Payload.
4854 * Changed Command Payload implementation to use the new Argument
4855 Payload. Changed command_xxxx_payload to command_payload_xxxx
4856 to comply with SILC coding conventions.
4858 * Added suppport for Argument Payload handling in Notify Payload
4859 implementation as protocol requires it. Added the new support
4860 into server and client lib as well.
4862 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Added support for multiple nicknames on same channel. [n] is
4865 added locally to the nickname if there are more than one same
4866 nicknames on the channel.
4868 * Server now sends all nicknames that matched WHOIS request.
4869 Client also shows the list received from server.
4871 * Added TOPIC command to client side. User can now set and show
4872 current topic on channel.
4874 * Added MOTD command to client and server. Also, server sends the
4875 motd when client connects to the server.
4877 * Changed version strings to comply ISO 8601.
4879 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Fixed protocol error handling in client library. It should now
4882 cope even if the SKE fails for some reason.
4884 * Made new protocol specification drafts for submitting to IETF.
4886 * Implemented TOPIC command to server in silcd/command.c.
4888 * Added two new notify types into lib/silccore/silcnotify.h:
4889 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4890 notify nickname change and topic setting/change on a channel.
4892 * API change of command_reply operation in client library. The
4893 application gets now the status type received from server as well.
4895 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4897 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4899 * Cras fixed and optimized the packet handling even further and
4900 it should work now. Minor change to the prototype of function
4901 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4903 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4905 * Added new function into lib/silcutil/silcschedule.[ch]:
4906 silc_schedule_with_fd to select() a specified fd. The function
4907 returns after timeout expires or data arrives or goes. The
4908 function is used by packet routines to wait that all data is
4909 received from network.
4911 * Fixed data reading from network in lib/silccore/silcpacket.c.
4912 The code now assures that all data is read from the fd and then
4913 continues packet processing. This was a bug fix since the code
4914 used to drop some data in some circumstances.
4916 * Added new function into lib/silcclient/client.[ch]:
4917 silc_client_start_key_exchange to start key exchange after
4918 connection has been established to server. The code internally
4919 now uses this funtion but its main purpose was to provide it
4920 for applications that perform their own connecting. After
4921 application has created a connection it merely calls this
4922 function to start the key exchange between client and server.
4923 The library takes care of everything else after that.
4925 Updated also lib/silcclient/README to explain the usage of
4928 * Do not send to application information that connection has
4929 been established. Application gets notified it by connect
4932 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4934 * Applied cras's patch to add silc_schedule_one function. The
4935 function runs scheduler once and returns.
4937 * Fixed the scheduler after cras messed it up. The timeout
4938 handling works now as it's supposed to work.
4940 * Added into lib/silccore/ silcnotify.h to include notify
4941 message types support. Changed silc_server_send_notify*
4942 functions, in server.[ch], to support those new notify types.
4943 Added the support for the notify types into client library,
4944 as well. Added new notify client operation into ops.h in
4947 * Changed silc_server_packet_send_to_channel to send normal
4948 packets instead of just channel message packets. The function
4949 is now used to send the notify packets to channels. It is not
4950 used to send channel message packets anymore, as server never
4953 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4954 va_arg()s as it seems to require it nowadays. I guess, if SILC
4955 is compiled with older va_arg() the new code should work anyway.
4957 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4959 * Splitted core library. Core library (lib/silccore) includes
4960 now only SILC protocol specific core (and common) components.
4961 Created new utility library (lib/silcutil) that includes more
4962 generic purpose stuff. The stuff for util library was taken
4963 from the old core library. This was minor and easy split.
4965 * Created SILC Client Library (lib/silcclient) that includes
4966 implementation of the SILC client without user interface. This
4967 was major move from silc/ directory. The code has been changed
4968 so that it is transparent towards the user interface. The
4969 silc/ directory includes now the same user interface as before
4970 and it uses the new client library. Read lib/silcclient/README.
4971 Basicly, the client library performs everything else related
4972 to SILC except user interface handling. Also, configuration
4973 files are considered to be part of user interface and library
4974 does not handle them.
4976 This change also changed a lot of structures, function naming etc.
4977 Most important change was that SilcClientWindow object was
4978 renamed to SilcClientConnection in the client library. Created
4979 also new file lib/silcclient/ops.h. Also added new files
4980 silc/local_command.[ch] and silc/client_ops.[ch].
4982 All these changes were made to make it easier for user interface
4983 designers to create what ever user interface for the SILC client
4986 It is also expected that the server will be moved to lib
4987 directory as well and SILC Server Library will be created;
4988 sometimes in the future.
4990 * Removed Local commands from lib/silccore/silccommand.h as
4991 they are application specific and new client library does not
4992 handle any of those anymore.
4994 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4995 old client implementation in silc/.
4997 * Added support for callback functions in SILC_LOG_* macros.
4998 Application can now set its own callbacks that will be called
4999 instead of using the default functions that will always print
5000 the debug messages to stderr (or stdout). Also, debugging can
5001 now be disabled by setting silc_debug to FALSE and re-enabled by
5002 setting it to TRUE. Note, that logging will still work even
5003 if debugging is disabled.
5005 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
5006 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
5007 silc_log_reset_debug_callbacks.
5009 * To enable debugging in silc client one must give now -d
5010 option on command line.
5012 * Changed silc_schedule_init to automatically allocate task queues
5013 if they are not allocated before calling it.
5015 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5017 * Added GMP 3.1 into math library.
5019 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5021 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5022 a channel in SILC network. The packet is used by servers and
5023 routers to notify other routers that user has left a channel.
5024 This little feature was missing until now. Added the feature
5025 to protocol specification as well.
5027 Added functions: silc_server_send_remove_channel_user and
5028 silc_server_remove_channel_user into server.[ch].
5030 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5031 lib/silccore/silcpacket.h. However, they are not implemented
5034 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5036 * Fixed joining to a channel and sending channel messages
5037 between server and router. The channel message sending should
5038 now work inside a cell.
5040 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Fixed the private message sending between server and router.
5043 The private message sending should now work inside a cell.
5045 * Added silc_server_replace_id into server.[ch] to replace
5046 existing ID in the SILC network.
5048 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5049 and silc_idlist_replace_server_id into idlist.[ch] in server.
5051 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5053 * Fixed the server to server connections. Server can again now
5054 connect to router. Router to router connections probably does
5057 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Added dynamic protocol registering support. Now protocols can
5060 registered and unregistered on the fly. Patch by cras.
5062 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5064 * Added lib/contrib directory to hold routines that some platforms
5065 don't have but are needed by SILC.
5067 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5068 into lin/contrib to provide getopt() and getopt_long() for
5069 those who don't have it.
5071 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5073 * Added AWAY command to client. When away message is set and
5074 client receives a private message packet the client automatically
5075 replies to the sender with the away message.
5077 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5078 bug seemed to be the cause of recent problems when compiling
5081 * Added version detection support to SKE protocol specification
5082 and added the new changes to the SKE implementation as well.
5083 There were other minor changes in the SKE protocol as well.
5085 Many changes in lib/silcske/silcske.[ch] and in
5086 lib/silcske/payload.[ch].
5088 * Added ^U functionality, clear input line. Patch from cras.
5090 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5092 * Mainly small bugfixes on core library. Fixed some debugging
5093 logging and buffer overflow in silclog.c.
5095 * Updated config.sub and config.guess on the distribution tree.
5097 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5099 * Added command lagging support in server. Client may execute
5100 commands now only once in two seconds.
5102 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5104 * Optimized packet reception. MAC computation and checking is now
5105 also more optimized. A lot previously duplicated code is now
5106 used as generic by both client and server.
5108 * Fixed key pair generation in clientutil.c
5110 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5112 * Added into lib/silccore/silcbufutil.[ch] new function;
5113 silc_buffer_realloc.
5115 * Moved generic packet sending/encryption functions to
5116 lib/silccore/silcpacket.[ch] from client and server. Some
5117 rewriting of the functions.
5119 * Moved all generic packet reception/decryption functions to
5120 lib/silccore/silcpacket.[ch] from client and server. The
5121 packet processing is now much cleaner in both client and server.
5122 These were major changes in both client and server.
5124 * Created many common functions in server to do packet sending.
5125 Previously code were duplicated a lot, this has been removed
5128 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5130 * Rewrote major parts of the ID cache system. Don't know
5131 whether it is better now or not but at least the API is more
5134 * Major rewrite on ID cache stuff on client because of the ID
5135 cache API changes. Added idlist.c to client.
5137 * Also major rewrite on ID cache stuff on server as well.
5138 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5139 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5140 in hand, instead they are all put into the ID cache system now.
5141 All server_idlist_* routines uses ID cache now instead of
5142 traversing its own lists (those lists does not exist anymore).
5143 SilcIDList though still exists. Also, SilcXXXEntry's are
5146 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5148 * Finally made the SKE implementation compliant to the protocol
5149 specification. All mp integers are now binary encoded as
5150 opposed being HEX encoded.
5152 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5155 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5156 functions: silc_[encode/decode]_pem. Also added function
5157 silc_encode_pem_file to PEM encode with newlines ('\n') for
5160 * SILC public keys are now encoded either PEM or binary. Same
5161 option is for private keys as well. By default private keys
5162 are binary encoded and public keys PEM encoded. Silly HEX
5163 encoding were removed.
5165 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5166 function to create fingerprints.
5168 * Fixed a bug in SHA1; does not change the original data anymore.
5170 * Partly implemented INFO command on client and server side.
5171 Fixed CLEAR command. Changes to SERVER command; show current
5172 server(s) when giving command without arguments. Added
5173 VERSION command to client.
5175 * Added check to server that unregistered connections cannot
5176 execute commands (unless it is specificly allowed).
5178 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * Fixed screen refresh.
5182 * Fixed channel joining bug from client. On some circumstances
5183 client tried to join to a channel it had already joined.
5185 * Added public key verification process into client's protocol.c.
5186 The client now verifies the public key from user and saves
5187 it into ~./silc/serverkeys/ directory.
5189 Added into: clientutil.[ch]: silc_client_verify_server_key.
5191 * Changed SKE protocol's silc_ske_initiator_finish function
5192 to accept callback function that verifies the received public
5193 key. Removed old silc_ske_verify_public_key function.
5195 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5197 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5198 silc_pkcs_private_key[_data]_set.
5200 * Made the password and public authentication more cleaner in
5201 server's protocol.c.
5203 * Removed historic and obsolete protocol `channel_auth' from
5204 both client and server.
5206 * Removed wrong way of sending command status messages from
5207 server to client in server's command.c. The old way violated
5208 protocol specification.
5210 Changes to silccore/silccommand.[ch]: removed
5211 silc_command_encode_status_payload -> not needed anymore,
5212 changed silc_command_encode_payload_va to accept extra
5213 argument on variable argument list. The argument type must
5214 now be provided to the function. Also, added new function:
5215 silc_command_encode_reply_payload_va which is same as
5216 normal command_encode_payload_va except command status type
5217 is provided as extra argument.
5219 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5221 * Added ~./silc directory handling. The directory includes the
5222 public and private keys for the client.
5224 Added silc_client_check_silc_dir, silc_client_create_identifier
5225 and silc_client_load_keys.
5227 * Implemented SILC protocol compliant public key. Added public
5228 and private key saving to and loading from files.
5230 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5231 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5232 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5233 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5234 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5236 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5237 silc_pkcs_load_[public/private]_key.
5239 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5241 * Added silc_server_get_route (route.[ch]) to get connection
5242 data for the fastest route for given ID.
5244 * Implemented INVITE command on client and server. The command
5245 were re-defined in the SILC Protocol Specification and the
5246 implementation now complies with the specification.
5248 * Implemented PING command on client and server.
5250 * Implemented NAMES command on client and server. The server side
5251 supports currently only normal server not router server yet.
5252 Some changes to NAMES definition in SILC protocol specification.
5254 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5256 * Implemented LEAVE command on client and server.
5258 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5259 again. This change was made to the protocol as well. Server
5260 should not violate the protocol specification anymore.
5262 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5264 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5265 was tested. SOCKS4 was not but should work anyway.
