3 * Assure that the packet length digged from the actual packet
4 is something sensible in the silc_packet_decrypt_rest_special
5 in lib/silccrypt/silcpacket.c.
7 * Free and NULL the allocated pointer in silc_hmac_alloc if
8 the HMAC allocation fails. The affected file is
9 lib/silccrypt/silchmac.c.
11 * Print the selected security properties to the log files in
12 the server. Affected file silcd/protocol.c.
14 * Add SKE's reference counter even if calling the completion
15 callback manually. Otherwise it goes negative, although it
16 does not cause any problems. The affected file is
17 lib/silcske/silcske.c.
19 * Remove the client entry with short timeout after giving the
20 KILL command. Affected file lib/silcclient/command.c.
22 * Fixed to send error reply in WHOIS and IDENTIFY commands in
23 case all found clients are already disconnected (WHOWAS would
24 found them) in the server. Affected file silcd/command.c.
26 * Update the last_receive (time of last data received) to be
27 updated only when received private or channel message so that
28 the idle time showed in WHOIS makes more sense.
30 * Added boolean field `valid' in to the SilcClientEntry in the
31 client library to indicate whether the entry is valid or not.
32 This fixes the nickname change bug on channel when changing
33 the nickname to be same than the old (like nick to Nick) the
34 nickname formatter doesn't set the new nick anymore to Nick@host.
35 Affected file lib/silcclient/idlist.[ch].
37 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
39 * Check that the public key exists in the GETKEY command before
40 trying to encode it. Affected file silcd/command.c.
42 * Print some notifications on received public keys with GETKEY
43 command in the Irssi SILC Client. Affected files are
44 irssi/src/fe-common/silc/module-formats.[ch],
45 irssi/src/silc/core/client_ops.c.
47 * Use IDENTIFY command to resolve the server information in the
48 GETKEY command instead of INFO command. Affected file
49 lib/silcclient/command.c.
51 * All command reply functions in the client library now calls
52 the pending command reply callbacks even if an error has
53 occurred. The server has done this a long time and now it was
54 time to move the client library to this as well. Now all
55 errors can be delivered back to the pending command reply
56 callbacks if necessary. Affected files are
57 lib/silcclient/command[_reply].[ch].
59 * Change the nickname on disconnection back to the username
60 because in reconnect the server will enforce it to it anyway.
61 Affected file irssi/src/silc/core/silc-servers.c.
63 * Fixed a config file parsing bug in the Irssi SILC client.
64 Affected file irssi/src/silc/core/clientconfig.c.
66 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
68 * When printing the channel mode on JOIN, verify that the
69 channel key and channel's HMAC are valid. Affected file
70 irssi/src/silc/core/client_ops.c.
72 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
74 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
75 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
76 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
78 * Removed channel key rekey task deleting from the function
79 silc_server_save_channel_key. Affected file silcd/server.c.
80 Added explicit timeout task context instead that is used to
81 delete the task if we are registering a new task before the
84 * When channel key rekey occurs the client library now saves
85 the old channel key for a short period of time (10 seconds) and
86 is able to use it in case some is still sending channel
87 messages encrypted with the old key after the rekey. Affected
88 file lib/silcclient/[idlist.h|client_channel.c].
90 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
92 * Added check to the silc_server_new_id_real to not accept
93 new ID if it is the sender's own ID. Affected file is
94 silcd/packet_receive.c.
96 * Assure that we do not announce ourself or the one we've
97 sending our announcements when we're router and are announcing
98 servers to our primary router. Affected file silcd/server.c.
100 * Fixed silc_server_command_identify_check_client to assemble
101 correct WHOIS packet. It send corrupted WHOIS packet and
102 caused problem with router to router connections. Affected
103 file silcd/command.c.
105 Fixed also silc_server_command_whois_check the same way
106 as for the IDENTIFY command.
108 * Added new SilcIDListStatus to the server in the SilcIDListData
109 structure. The status now includes the current status of
110 the entry (like registered, resolved etc.). Affected file
111 silcd/idlist.[ch]. Defined a bunch of different status types
112 as well. This replaced the old boolean registered field as well.
114 Added resolve_cmd_ident field to the SilcClientEntry structure
115 too so that if the entry is for example being resolved so
116 another command may attach to the same pending command reply
117 without requiring to resolve the same entry again. This concept
118 should optimize the WHOIS and the IDENTIFY resolving under
119 heavy load by taking away unnecessary resolving for entries
120 that are being resolved already.
122 Added support for adding multiple pending commands for one
123 command idenfier. Affected file silcd/command[_reply].[ch].
125 * Fixed WHOIS and IDENTIFY save to remove the cache entry
126 before deleting the data. Otherwise the hash table will have
127 freed data in comparison functions. Affected file is
128 silcd/command_reply.c.
130 * Fixed silc_idlist_replace_client_id to add the new entry to
131 the cache with NULL nickname. Otherwise there will be invalid
132 memory as the nickname after the nickname is freed. Affected
133 file silcd/packet_receive.c.
135 * Fixed the silc_idlist_get_clients_by_hash. The entries was
136 saved into wrong slots because the previous number of entries
137 was not taken into account. Affected file silcd/idlist.c.
138 Fixed same thing in silc_idlist_get_clients_by_nickname too.
140 * If we are router and we receive JOIN notify to a channel that
141 does not have any users then notified client is marked as the
142 channel founder, as it is it. The affected file is
143 silcd/packet_receive.c
145 * Added to the extended hash table API's table_del_*ext functions
146 the destructor as argument too, so that the caller can decide
147 which destructor to use or whether to use destructor at all.
148 Affected file lib/silcutil/silchashtable.[ch].
150 * Fixed ID Cache purging. It actually deleted the entries from
151 the hash table after the data was freed. The hash table ended
152 up comparing freed memory. The affected file is
153 lib/silccore/silcidcache.c.
155 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
157 * Fixed Irssi SILC client's KILL command's HELP syntax.
159 * The USERS command now resolves the detailed user information
160 if the userinfo field is missing. Affected file is
161 lib/silcclient/command_reply.c.
163 * Do not print error in silc_file_read if the read file does
164 not exist. Just silently return NULL. Affected file is
165 lib/silcutil/silcutil.c.
167 * Fixed the silc_log_output to not wine about NULL filename
168 and to not create some bogus " " filename. Affected file is
169 lib/silcutil/silclog.c.
171 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
173 * Fixed various printing bugs on the user interface in the
174 Irssi SILC Client. Minor changes that were forgotten from
177 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
179 * Fixed the configure.in.pre and the compilation and distribution
180 environment to support the new autoconf 2.52. That version is
181 now required to compile the CVS trunk.
183 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
185 * Renamed function silc_parse_nickname to silc_parse_userfqdn
186 to generally parse user@fqdn format strings. Affected file
187 lib/silcutil/silcutil.c.
189 * Added nickname_format and nickname_force_format fields to the
190 SilcClientParams structure. The first one defines the format
191 for the nicknames that the library will enforce if the receives
192 multiple same nicknames. The second one is boolean value and
193 can be used to force the library to always enforce the format
194 to the nicknames regardles whether there are multiple nicknames
195 or not. This configurable formatting was employed to flexibly
196 support accessing multiple nicknames from the user interface.
197 The userinterface can now set the nicknames to what ever format
198 they prefer. Affected file lib/silcclient/silcapi.h.
200 Added function silc_client_nickname_format to the file
201 lib/silcclient/idlist.c. It performs the nickname formatting.
203 Added new field `hostname´ to the SilcClientEntry context.
204 It holds the hostname of the client. Affected file is
205 lib/silcclient/idlist.h.
207 * Irssi SILC Client sets the nicknames in nick@hostn format.
208 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
209 irssi/src/silc/core/silc-core.c.
211 The WHOIS printing now also shows both the real nickname and
212 the formatted nickname so that user knows how to access the
213 user if there are multiple same nicknames cached. Affected
214 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
215 printing formatting too to take the hostname now as a separate
216 argument. The Affected file is
217 irssi/src/fe-common/silc/modules-formats.[ch].
219 * Changed the silc_client_get_clients_local to accept the formatted
220 nickname as argument. It accepts the real nickname too but the
221 formatted nickname can be used to find the true entry from
222 multiple entries. Affected file lib/silcclient/silcapi.h and
223 lib/silcclient/idlist.c.
225 * Added nickname_format_parse field to the SilcClientParams.
226 It is a callback function provided by the application to parse
227 the nickname out of the formatted nickname string. The library
228 calls it to get the nickname from the formatted string. Since
229 the application generally knows better the format of the nickname
230 string it parses it instead of the library, even though library
231 encodes the formatted string. If the callback function is not
232 provided then the library will use the string as is. The
233 affected file is lib/silcclient/silcapi.h.
235 * All the nickname strings passed to the client library in
236 commands are now expected to be formatted nickname strings.
237 If the command does not support the formatted nickname string
238 it will assume that the sent string is the actual nickname.
239 Affected file lib/silcclient/command.c.
241 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
243 * Added public key authentication support to OPER and SILCOPER
244 commands in the client library. Affected file is
245 lib/silcclient/command.c.
247 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
249 * Changed the get_auth_methdod client operation to be asynchronous.
250 It can be async if the application resolves the authentication
251 method from the server during the negotiation. Added new
252 SilcGetAuthMeth completion callback that the application will
253 call after resolving the authentication method.
255 Added function silc_client_request_authentication_method that
256 the application can use to resolve the authentication method
257 from the server. Added also SilcConnectionAuthRequest callback
258 that the library will call after the server has replied. The
259 application can call this function if it does not know the
260 current authentication method.
262 Affected files are lib/silcclient/client.c and
263 lib/silcclient/silcapi.h.
265 * The Irssi SILC client now automatically resolves the authentication
266 method incase any configuration information is not present (and
267 currently there never is). The affected file is
268 irssi/src/silc/core/client_ops.c.
270 * Fixed public key authentication from the client library.
271 Affected file lib/silcclient/protocol.c. Changed also the
272 protocol specification about the public key authentication in
273 the connection authentication protocol. The actual data to be
274 signed is now computed with a hash function before signing.
276 * Fixed the public key authentication from the server as well.
277 Affected file silcd/protocol.c.
279 * Removed the mlock()'s from the memory allocation routines.
280 Affected file lib/silcutil/silcmemory.c. The ./configure does
281 not check anymore for the mlock(). Affected file is
284 * Fixed USERS command in server to allow the execution of the
285 command for private and secret channels if the client sending
286 the command is on the channel. Affected file silcd/command.c.
288 * Fixed silc_client_get_clients_local to return the clients
289 count correctly. It could return wrong value. Affected file
290 lib/silcclient/idlist.c.
292 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
294 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
295 types. The assembler optimizations seemed not to like 64-bit
296 data types. The assmebler optimizations thus are now enabled
297 also for BSD systems as opposed to only enable them for Linux.
299 * Do not check for threads at all on BSD systems. Affected
300 file configure.in.pre.
302 * Removed -n and -h options from the Irssi SILC Client since
303 they are not used in silc.
305 * Fixed the prime generation to assure that the first digit
306 of the generated random number is not zero since our conversion
307 routines does not like number strings that starts with zero
308 digit. If zero digit is seen the random number is regenerated.
309 This caused some corrupted RSA keys when the zero first digit
310 was met. Affected file lib/silcmath/silcprimegen.c.
312 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
314 * Fixed WIN32 configuration in the ./configure script.
315 Fixed to include xti.h on environments that has it.
316 Patches by Carsten Ilchmann and andrew.
318 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
320 * Changed the silc_id_create_client_id to be collision
321 resistant. It is now assured that there cannot be created
322 two same client ID's. I suspect that some weird bugs in
323 the server were actually caused by duplicate Client IDs.
324 Affected file silcd/serverid.[ch]. A router receiving
325 new ID now also assures and informs the sending server
326 if the ID caused collision.
328 * Changed the silc_id_create_channel_id to also assure that
329 there are no collisions.
331 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
333 * Statement about ignoring the Mutual Authentication flag when
334 performing rekey with PFS was a bit misleading. It is ignored
335 if it was set in the initial negotiation, it cannot be even
336 set in the rekey. Fixed in the ke-auth draft. Started the
337 new versions of the protocol drafts in the doc/.
339 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
341 * Fixed a bug in silc_client_command_identify_save when saving
342 new channel information. The channel name was no duplicated
343 and caused crash on exit. Affected file is
344 lib/silcclient/command_reply.c.
346 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
348 * Fixed the getkey command handling in the server. Send just
349 empty OK reply to the sender if the key could not be fetched
350 (but everything else was ok, like the key just was not available).
351 Changed the public key parameter to optional in the protocol
352 specs so that empty OK reply can be sent. Affected file
355 Added a message to Irssi SILC client to tell to user if the
356 server did not return a public key.
358 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
360 * Fixed a channel key regeneration bug. It registered new
361 timeout tasks exponentially until all system resources were
362 used. Affected file silcd/server.c.
364 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
366 * Added the SILC Document generator to the scripts/silcdoc.
367 It can be used to generate the Toolkit Reference Manual out
368 of the source tree. Internally it will also use the RoboDoc
369 generator now imported in util/robodoc.
371 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
373 * Added couple of return's in rekey protocol if error orccurred
374 during the protocol. The execution must be terminated.
375 Affected file silcd/protocol.c. Also, terminate the protocol
378 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
380 * The client's Client ID was created initally from the wrong
381 nickname (it could have been in format nick@host) in the
382 silc_server_new_client. Affected file silcd/packet_receive.c
384 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
386 * Added some SILC_LOG_ERROR's to various error conditions
387 if client could not be added to ID cache. Affected files
388 silcd/packet_receive.c and silcd/server.c.
390 * When client's sock->user_data is freed, NULL also the
391 client->router and client->connection pointers. Added check
392 for these pointers being NULL to various places around the
393 code. Affected file silcd/server.c.
395 * Added client->data.registered == TRUE checks to various
396 places around the code to assure that unregistered client's
397 are not handled when it is not allowed. Affected file
400 * Added `bool registered' fields to all
401 silc_idlist_[server|client]_get_* routines to indicate whether
402 the fetched client needs to be registered or not. Affected
403 file silcd/idlist.[ch].
405 * Add your own entry as registered to the ID cache in the
406 server. Affected file server.c.
408 * Fixed a bug in silc_server_new_server. The SilcServer was
409 set as the new server's context instead of SilcServerEntry.
410 This naturally caused some weird bugs.
412 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
414 * Do not delete the channel rekey task when adding it
415 for in silc_server_create_channel_key.
417 * Changed the silc_server_create_channel_key to return
418 TRUE or FALSE to indicate the success of the channel key
421 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
423 * Fixed MSVC++ project files and added missing files to
424 Makefiles under win32/.
426 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
428 * Do not add TCP_NODELAY flag if the operating system
429 does not have it defined. Affected files are
430 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
432 * Fixed buffer overflow from Irssi SILC Client. Affected
433 file irssi/src/fe-common/core/themes.c.
435 * Fixed double free in client library in the file
436 lib/silcclient/client.c when disconnecting from server.
438 * Applied double free patch from cras to Irssi SILC client.
439 Affected files irssi/src/core/[modules/expandos].c
441 * Fixed the disconnection handling to Irssi SILC Client.
442 The application must call silc_client_close_connection
443 in ops->connect client operation in case of failure of
444 the connection. Affected file is
445 irssi/src/silc/core/client_ops.c.
447 * Do not set sock->protocol to NULL in the function
448 silc_client_close_connection after executing the protocol's
449 final callback since the sock might not be valid anymore.
450 Affected file lib/silcclient/client.c.
452 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
454 * Do not enable SILC_THREADS if the linking with libpthread
455 did not happen. Affected file configure.in.pre.
457 * Added notion to protocol specification that server must
458 verify the sent authentication payload with CMODE when
459 setting the channel founder key. Implemented it to the
460 server. Affected file silcd/command.c.
462 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
464 * Added _EXTRA_DIST SILC distribution variable to the
465 distributions file. It is used to conditionally add extra
466 files or directories to the specific distribution. Affected
467 files ./prepare, Makefile.am.pre and distributions.
469 Removed the `_' from the start of the distribution names.
472 * Added README.WIN32 for instructions to compile the Toolkit
475 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
477 * Fixed a double free in disconnection in the server. Affected
478 file is silcd/server.c.
480 * Fixed the lib/silcske/groups.c to work now also with GMP
481 MP library. The string conversion did not work when using
482 specific base and the base is indicated in the string as well.
484 * Created win32/ directory which now includes MSVC++ specific
485 stuff so that toolkit (DLLs) may be compiled with MSVC++.
486 It will appear only in the toolkit distribution
488 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
490 * Changed the key material distribution function in case when
491 the hash output is too short. The data is now concatenated
492 a bit differently than it used to. Made the change to the
493 SKE protocol specification.
495 * Added better GMP detection to configure.in.pre. A patch
498 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
500 * Fixed a minor bug in SKE that might cause some problem on
501 some platforms. Affected file lib/silcske/silcske.c.
503 * Added the cookie checking for initiator in the SKE. It checks
504 that the responder returns the sent cookie unmodified. The
505 affected file is lib/silcske/silcske.c. Added new SKE
506 error type INVALID_COOKIE that can be sent during the
507 negotiation. Fixed some memory leaks as well.
509 * Added the "invalid cookie" error message to Irssi SILC client's
512 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
514 * Added `task_max' field to the SilcClientParams to indicate
515 the maximum tasks the scheduler can handle. If set to zero,
516 default values are used. Affected file lib/silcclient/silcapi.h.
518 * Fixed memory leaks in silc_client_close_connection. Affected
519 file lib/silcclient/client.c.
521 * Added silc_client_del_client_entry to client library to free
522 all memory of given client entry. Affected file is
523 lib/silcclient/idlist.[ch].
525 * Added new functions silc_client_del_channel and
526 silc_client_del_server to delete channel and server entries.
527 Affected file lib/silcclient/[silcapi.h/idlist.c].
529 * Removed silc_client_del_client_by_id from silcapi.h.
531 * Fixed the INFO command to return the server's own info
532 correctly when querying by Server ID. Affected file is
535 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
537 * Removed the non-blocking settings in WIN32 code in the
538 silc_sock_[read/write] and added SleepEx instead. Affected
539 file lib/silcutil/win32/silcwin32sockconn.c. The availability
540 of input data is now checked with FIONREAD and ioctlsocket.
542 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
544 * Call silc_schedule_task_del_by_context in the
545 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
546 Affected file lib/silccore/silcprotocol.c.
548 * Call silc_protocol_cancel for active protocols in the
549 silc_server_close_connection if the funtion
550 silc_server_free_sock_user_data has not been called.
551 Affected file silcd/server.c.
553 * Generic tasks cannot be deleted using the del_by_fd
554 task deleting function since generic tasks does not match
555 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
557 * Added a notion to SILCOPER help file that the SILCOPER works
558 only on router server, not on normal server.
560 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
562 * Added for WIN32 support for the new scheduler as well.
563 Affected file lib/silcutil/win32/silcwin32schedule.c.
565 * Fixed the SHA1 implementation to work on various platforms.
567 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
569 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
570 API. It is part of the scheduler now. Everything else is
571 as previously but some functions has changed their names.
572 Checkout the lib/silcutil/silcschedule.h for the interface.
573 Updated all applications to use the new interface. Affected
574 files are lib/silcutil/silcschedule.[ch].
576 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
578 * Found a bug in the SKE implementation. The HASH value,
579 specified by the protocol, was not computed correctly. The
580 public key of the responder was not added to the computation
581 even though it is mandatory. Affected file lib/silcske/silcske.c.
582 This unfortunately causes incompatibilities with older
585 * Added WIN32 specific network init and uninit functions:
586 silc_net_win32_init and silc_net_win32_uninit to init and uninit
587 the Winsock2. Affected file lib/silcutil/silcnet.h and
588 lib/silcutil/win32/silcwin32net.c.
590 * Set the socket always to nonblocking mode on WIN32 after
591 reading data or writing data. Affected file is
592 lib/silcutil/win32/silcwin32sockconn.c.
594 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
596 * Fixed various compilation problems under WIN32. Affected
597 files lib/silcutil/win32/silcwin32thread.c and
598 lib/silcutil/win32/silcwin32schedule.c.
600 * Removed all _internal.h #includes from public header
601 files. Internal headers must never be included from
604 Removed also the lib/silcske/payload_internal.h file.
606 * All include files that may be needed (public and some others
607 included by the public headers) by application developers are
608 now copied to the ./includes directory. It does not copy any
609 internal headers. Affected file Makefile.defines.pre and all
610 Makefile.am's under lib/ and subdirs.
612 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
614 * Do not change the ~/.silc directory's permissions automatically.
615 Affected file irssi/src/silc/core/clientutil.c.
617 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
619 * Do not cancel the protocol in silc_server_close_connection
620 it might cause recursion. Now cancelled in the function
621 silc_server_free_sock_user_data. Affected file silcd/server.c.
623 * Fixed the silc_server_remove_clients_by_server to regenerate
624 the channel keys correctly finally. Added also new function
625 silc_server_remove_clients_channels to actually do it.
626 Affected file silcd/server.c.
628 * Fixed the silc_server_new_channel to not crash by giving
629 wrong router to the new channel. Affected file is
630 silcd/packet_receive.c.
632 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
634 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
635 which is given as argument to the silc_client_alloc now.
636 It can be used to configure the client and set various parameters
637 that affect the function of the client.
639 * The USERS command in server did not check whether the channel
640 is private or secret. Affected file silcd/command.c.
642 * Added new argument to the USERS command in protocol specification.
643 The USERS command now can take the channel name as argument
644 as well. Added support for this in client and server and
645 updated the protocol specs.
647 * Completed the GETKEY command in client. It can be now used
648 to fetch also servers public key not only some clients.
649 Affected files lib/silcclient/command[_reply].c.
651 * Added silc_client_get_server to return server entry by the
652 server name. Affected files lib/silcclient/silcapi.h and
655 * Redefined the IDENTIFY command in protocol specification to be
656 more generic. It now can be used to query information about
657 any entity in the SILC Network, including clients, servers and
658 channels. The query may be based either the entity's name
659 or the ID. Added support for this in both client and server.
661 Affected files silcd/command.c and lib/silcclient/command.c
664 * Optimized the WHOIS and WHOWAS commands in the server. Removed
665 the _from_client and _from_server functions. Affected file
668 * Added silc_client_get_channel_by_id_resolve to the file
669 lib/silcclient/silcapi.h to resolve channel information by
670 its ID. Added also silc_client_get_channel_by_id that
671 does not resolve it from the server.
673 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
675 * Added SilcServerEntry context into the client library
676 to represent one server. The INFO command now allocates
677 these to save the resolved server info. For now on the
678 client library will also keep information about servers,
679 connected and resolved with INFO.
681 The INFO command now allocates the SilcServerEntry context
682 and saves the server info there. The COMMAND_REPLY in
683 the INFO now returns the parameters to application in
684 same order as defined in the protocol specification.
686 The entries are cached in the client->server_cache.
688 * The INFO command is now issued after received the Client ID
689 from the server. Affected file lib/silcclient/client.c.
691 * The CMODE_CHANGE notify may now return also an SilcServerEntry
692 to the application as the mode changer might be server.
693 It is guaranteed that NULL is not returned anymore to the
694 application. Affected file lib/silcclient/client_notify.c.
696 The ID Type is now also passed to the application so that
697 it can check whether the returned entry is SilcClientEntry
700 Added new function silc_client_get_server_by_id to return
701 the server entry by ID. Affected files are the
702 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
704 * Do not create the channel in the Irssi SILC Client when issuing
705 the JOIN command but when received the sucessful JOIN command
706 reply. Otherwise the channel might get created even though we
707 could not join it. The Affected file is
708 irssi/src/silc/core/[silc-channels.c/client_ops.c].
710 * Fixed a channel joining bug in router. The router must also
711 check the channel modes, invite and ban lists etc. when serving
712 the JOIN command sent by normal server. Affected file is
713 silcd/command.c. The router now resolves the client's
714 information from the server who sent the JOIN command if it
715 does not know it, and processes the JOIN command only after
718 * Changed the SilcCommandCb to take new argument; void *context2.
719 Affected file lib/silccore/silccommand.h
721 The second argument in the command callbacks in the server now
722 includes the SilcServerCommandReplyContext if the command was
723 called as pending command callback from the command reply.
724 Otherwise it is NULL. When called as pending the status of the
725 command reply will be checked and if it was erronous the
726 error will be sent to the original sender of the command.
727 This way the client always receives the error messages even
728 though the server was actually the one who received the error
729 when it resent the command to router, for example. Affected
730 files silcd/command[_reply].[ch].
732 * Fixed sending WHOWAS command's error message to client if
733 the requested client could not be found. It was missing.
736 * Changed the CMODE and CUMODE commands reply arguments in the
737 protocol specification. The Channel ID is now sent in both
738 of the commands to identify the channel. Implemented this
739 new feature to the client and server. Affected files
740 lib/silcclient/command_reply.c and silcd/command.c.
742 * Made better checks for invite and ban lists in the JOIN
743 command in server. Affected file silcd/command.c.
745 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
747 * The server now performs the incoming host IP/DNS lookup
748 using the silc_socket_host_lookup and thus does not block
749 the server anymore. Affected file silcd/server.c.
751 * Completed the multi-thread support for SILC Scheduler in
752 the lib/silcutil/silcschedule.c.
754 * Fixed the configure.in.pre to detect the pthread correctly
757 * Fixed a deadlock in silc_task_queue_wakeup in the file
758 lib/silcutil/silctask.c.
760 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
762 * Added new function silc_schedule_wakeup that is used in
763 multi-threaded environment to wakeup the main thread's
764 schduler. It needs to be used when a thread adds a new task
765 or removes a task from task queues. After waking up, the
766 scheduler will detect the task queue changes. If threads
767 support is not compiled in this function has no effect.
768 Implemented the wakeup mechanism to both Unix and WIN32
769 systems. Affected files are lib/silcutil/silcschedule.[ch],
770 lib/silcutil/unix/silcunixschedule.c and the
771 lib/silcutil/win32/silcwin32schedule.c.
773 * Added new function silc_task_queue_wakeup to wakeup the
774 scheduler by the specified task queue. Affected file
775 lib/silcutil/silctask.[ch].
777 * The silc_socket_host_lookup_start now wakes up the scheduler
778 after adding the timeout task. Affected file is
779 lib/silcutil/silcsockconn.c.
781 * The silc_socket_host_lookup is synchronous now if the threads
782 support is not compiled in. However, the callback is still
783 called asyncronously through the scheduler, anyway. Affected
784 file lib/silcutil/silcsockconn.c.
786 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
788 * Added new function silc_socket_host_lookup to perform
789 asynchronous IP and FQDN lookups for the socket connection.
790 Affected files lib/silcutil/silcsockconn.[ch].
792 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
794 * Added SILC_MUTEX_DEFINE to define the mutex on environments
795 that may or may not compile the mutex support in.
797 Changed the silc_mutex_alloc interface. It allocates the
798 mutex now to the sent pointer and returns TRUE or FALSE.
800 Affected file lib/silcutil/silcmutex.h.
802 * Wrote the SILC Task Queue interface to support multi-threads.
803 Affected file lib/silcutil/silctask.[ch].
805 * Wrote the SILC Scheduler to support multi-threads. Affected
806 file lib/silcutil/silcschedule.c.
808 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
810 * Implemented the SILC Mutex API and SILC Thread API for WIN32
811 in lib/silcutil/win32/.
813 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
815 * Defined SILC Mutex API and SILC Thread API and implemented
816 them for Unix. Affected files are
817 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
818 lib/silcutil/unix/silcunixmutex.c and
819 lib/silcutil/unix/silcunixthread.c.
821 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
823 * Fixed the silc_server_remove_clients_by_server's channel
824 key re-generation. The hash table handling was incorrect
825 and would not work with many channels. Affected file is
828 * Fixed some memory leaks around the server code.
830 * Rewrote the silc_server_get_users_on_channel to support IPv6
831 based Client ID's. Affected file silcd/server.c.
833 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
834 specification. However, a separate document must be written
835 to define the detailed signing procedure and the payload
836 associated with the flag. Defined the flag to the
837 lib/silccore/silcchannel.h as well.
839 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
841 * Changed the dynamic tables to static size tables in the
842 lib/silccrypt/silchmac.c.
844 * Removed GCC dependencies from the code. A patch by cras.
846 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
848 * Do not show the error "Error receiving packet bla bla"
849 in server if it really was not an error (-2 means that reading
850 is pending). Affected file silcd/server.c.
852 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
854 * Fixed a possible crash in silc_server_remove_clients_by_server
855 in silcd/server.c. Fixed there also some memory leaks.
857 * Fixed the silc_idlist_replace_client_id. It could replace
858 wrong key in the hash table. Affected file silcd/idlist.c.
860 * Do not check whether there are global users on the channel
861 if the channel->global_users is FALSE. Affected functions
862 silc_server_remove_from_one_channel and
863 silc_server_remove_from_channels in silcd/server.c. Also,
864 do not check if the removed client is local as we can be
865 sure that global client was not removed from the channel
866 and checking for global users is not needed.
868 * The silc_server_remove_clients_by_server now re-generates
869 the channel keys correctly for those channels that had
870 clients removed from them. Affected file silcd/server.c.
872 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
874 * Found the reason of random crashes in the server. We weren't
875 ignoring the SIGPIPE signal (which can be sent in write())
876 and it crashed the server. Affected file silcd/silcd.c.
878 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
880 * Assure that sock->user_data is not NULL in the function
881 silc_server_packet_send in silcd/packet_send.c.
883 * Disconnect the remote connection if it could not be added
884 to any ID lists in the server. The affected file is
887 * Check in silc_server_packet_send[_real/dest] that the
888 socket is not disconnecting and ignore the data if it is.
889 Affected file silcd/packet_send.c.
891 * Define inline to __inline on native WIN32 compilation.
892 Affected file includes/silcwin32.h.
894 * Added some explicit type casts for inline code since MSVC
895 require them. Affected files lib/silcutil/silcbuffer.h,
896 lib/trq/silcdlist.h and lib/trq/silclist.h.
898 * Print warning in log files from now on if the packet
899 decryption fails. Affected file silcd/server.c.
901 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
903 * Changed the `say' client operation's interface to accept
904 new `type' argument to indicate the type of the message sent
905 by the library. The application may filter the library's
906 messages according the type. The affected file is the
907 lib/silcclient/silcapi.h.
909 * Added two new functions to lib/silcclient/silcapi.h:
910 silc_client_del_client and silc_client_del_client_by_id.
911 Affected file lib/silcclient/idlist.c.
913 * Moved the clientincludes.h from includes/ to silc/ and
914 serverincludes.h from includes/ to silcd/.
916 * The modes for the CMODE and CUMODE are now passed as
917 uint32 for application with COMMAND_REPLY. The affected
918 file is lib/silcclient/command_reply.c.
920 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
922 * /WHOIS without arguments shows client's own information.
923 Affected file lib/silcclient/command.c.
925 * Changed PING to not accept any arguments. The specs
926 says that client can ping only the connected server so
927 requiring an argument is not needed. Affected file is
928 lib/silcclient/command.c.
930 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
932 * Fixed a fatal bug in private message sending and reception
933 encryption and decryption when using private message keys.
934 The implementation was incorrect and did not follow the
935 specification. It causd that some of the message were
936 lost since it did not use the sending and receiving keys
937 as the protocol suggests. This has been fixed and will cause
938 incompatibilities with older clients when sending private
939 message encrypted with private message keys. Affected files
940 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
941 and various other in Irssi SILC Client.
943 Added `responder' boolean argument to the functions
944 silc_client_add_private_message_key[_ske] to indicate when
945 the key is added as responder or initiator of the key
948 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
950 * Removed the silc_ske_check_version function and created
951 a SilcSKECheckVersion callback. Added also a function
952 silc_ske_set_callbacks that is now used to set all SKE
953 callbacks. The callback functions are not given to
954 the SKE functions anymore, but this function is used to
957 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
959 * Added `silc_version' argument to the silc_client_alloc
960 to define the version of the application for the library.
961 The library will use the version string to compare it
962 against the remote host's (usually a server) version
963 string. Affected file lib/silcclient/silcapi.h
965 * Added the KE protocol context to Key Agreement context
966 in client library so that we can abort the SKE if it
967 is in process when we get timeout. Affected file is
968 lib/silcclient/client_keyagr.c.
970 * Do not resolve the client ID forever if it returns in the
971 first time that such client does not exist. This was done
972 for example with private message. Affected file is
973 lib/silcclient/client_prvmsg.c.
975 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
977 * Do not add regex.h for WIN32. The affected file
978 includes/silcincludes.h.
980 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
981 not work yet 100%. It generates the DLL's automatically
982 when compiling with --with-win32 under cygwin.
984 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
986 * lib/contrib/regex.c is not compiled on WIN32.
988 * Added silc_net_get_socket_opt function to the
989 lib/silcutil/silcnet.h.
991 * Added includes/silcwin32.h for WIN32 specific includes
994 * Do not use ptime structure or any of the posix process
995 functions on WIN32 in lib/silccrypt/silrng.c.
997 * Added silc_gettimeofday to provide generic function
998 for struct timeval on all platforms. Added the function
999 to lib/silcutil/silcutil.h.
1001 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1003 * Moved the lib/silccore/silcsockconn.[ch] to the utility
1004 library as they clearly belong there. As a plus side we
1005 can make the actual socket connection routines platform
1008 Added also new generic function silc_socket_read and
1009 silc_socket_write (that used to be silc_packet_[read/write].
1010 The implementation of these are platform specific.
1012 * Added WIN32 specific routines of silc_socket_[read/write]
1013 to lib/silcutil/win32/silcwin32sockconn.c.
1015 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1017 * Added preliminary support for native WIN32 compilation under
1018 cygwin (using the -mno-cygwin option for GCC) to the
1019 ./configure.in.pre. The --with-win32 now prepares the
1020 compilation for native WIN32.
1022 * Rewrote the SILC Scheduler interface in the file
1023 lib/silcutil/silcschedule.h. The scheduler is now context
1024 based and does not have anymore any global static scheduler.
1025 Moved the Unix scheduler to the lib/silcutil/unix/ directory
1026 and created lib/silcutil/win32 directory for WIN32 based
1029 * Added Unix specific network routines to the
1030 lib/silcutil/unix/silcunixnet.c and the old
1031 lib/silcutil/silcnet.c includes now only generic routines.
1033 Added WIN32 specific network routines to the
1034 lib/silcutil/win32/silcwin32net.c.
1036 * Added Unix specific utility functions from the
1037 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1039 * Added WIN32 SILC Scheduler to the file
1040 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1043 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1045 * Do not handle JOIN notify in the server if the target client
1046 is not registered (idata->registered == FALSE). The affected
1047 file is silcd/packet_receive.c.
1049 * Update the nickrec->founder in event_cumode in the Irssi SILC
1050 client. Affected file irssi/src/silc/core/silc-channels.c.
1052 * Fixed the CUMODE_CHANGE notify handling in the server when
1053 server and router are announcing their clients on channels.
1054 Now the mode changes are saved and notified correctly. The
1055 affected file is /silcd/packet_receive.c.
1057 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1058 They really did not replace the cache entry in the ID Cache.
1059 Now they do that. Affected file silcd/idlist.c.
1061 * Fixed the KICK notify handling in the Irssi SILC client to
1062 update the channel records so that the kicked client does not
1063 appear to be on the channel. The affected file is
1064 irssi/src/silc/core/silc-channels.c.
1066 * Always update the conn->current_channel when executing command
1067 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1069 * Fixed the KILL notify handling in Irssi SILC client to remove
1070 the killed client on all channels.
1072 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1074 * Fixed the silc_parse_command_line to remove extra spaces
1075 from the start and end of the arguments. Affected file is
1076 lib/silcutil/silcutil.c.
1078 * Cancel and free any active protocol in the function
1079 silc_server_close_connection. Affected file silcd/server.c.
1081 * Cancel and free any active protocol in the function
1082 silc_client_close_connction. Affected file is
1083 lib/silcclient/client.c.
1085 * Do not execute the KILL command for clients that are in
1086 history (ie. they are not in the network). Affected file is
1089 * Fixed KILL notify handling, client does not crash anymore.
1090 Affected file irssi/src/silc/core/silc-channels.c.
1092 * Reduced the default packet buffer size from 2048 to 1024 in
1093 lib/silccore/silcpacket.c.
1095 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1096 counter to the SKE context that is incresed when the SKE library
1097 performs async operation outside the library. If the outside
1098 process frees the SKE context and FREED status will be set
1099 and the library will detect after the sync operation that the
1100 libary is freed. The affected files are
1101 lib/silcske/silcske[_status].[ch].
1103 * Resolve the client entry information in the function
1104 silc_client_channel_message to assure that NULL pointer is not
1105 passed as client entry to the application. */
1107 * Fixed the task timeout calculation to assure that there is
1108 never negative timeouts. The affected file is
1109 lib/silcutil/silcschedule.c.
1111 * Fixed the channel user mode notification sending in server.
1112 It was sent point-to-point to the router (or to server by router)
1113 but it needs to be destined to a channel. The routines now
1114 supports sending the channel user mode notifys to the channels
1115 when announcing clients and channels. Affected files are
1116 silcd/server.c and silcd/packet_receive.c.
1118 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1119 It did not actually replace the old channel entry in the cache.
1120 Affected file lib/silcclient/client_notify.c.
1122 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1124 * Fixed a possible crash in silc_packet_send_prepare. It now
1125 assures always that there is enough space in the buffer and
1126 at the tail area of the buffer (for MAC).
1128 Fixed the inbound buffer reallocation in silc_packet_read.
1129 It was old code and did not handle the reallocation correctly.
1132 The affected file is lib/silccore/silcpacket.c.
1134 * Fixed buffer overflow in silc_parse_nickname in the file
1135 lib/silcutil/silcutil.c.
1137 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1139 * make install generates new server keys only if there is not
1142 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1144 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1145 Added check that if the NOREPLY is set then we will not send
1146 the away message. This avoids infinite loop of away messages
1147 if both clients are away. The affected file is
1148 lib/silcclient/client_prvmsg.c.
1150 * Fixed client crash if /NICK was given without arguments.
1151 Affected file lib/silcclient/command.c.
1153 * Server does not send the invite list in INVITE command back
1154 to the client if the list was not altered. Added this notion
1155 to the protocol spec as well. Affected file silcd/command.c.
1157 Fixed possible crash in INVITE command by checking the
1158 value of silc_server_get_client_route command.
1160 * Fixed the INVITE notify type handling. The arguments are now
1161 taken in correct order and client does not crash. The affected
1162 file is irssi/src/silc/core/silc-channels.c.
1164 Removed the "Inviting xxx to channel" message from the
1165 client library away and let the application handle it.
1166 Affected file lib/silcclient/command.c. Added that message
1167 to Irssi SILC client's message formats.
1169 * Fixed CMODE command crash in client. It now checks the
1170 amount of arguments correctly and does not crash. The affected
1171 file is lib/silcclient/command.c.
1173 * Do not create new channel automatically in silc_channels_join
1174 but check whether the channel by that name already exists.
1175 Affected file irssi/silc/core/silc-channels.c.
1177 * Do not send the SERVER_SIGNOFF to router if the disconnected
1178 entity was the router. Affected file silcd/server.c.
1180 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1181 SILC client as it was missing from there.
1183 Added the handling of the KICK notify to the Irssi SILC client
1184 as it was missing. Added "you have been kicked" message to
1185 Irssi SILC client's message modules formats.
1187 Added the handing of the KILL notify to the Irssi SILC client
1188 as it was missing. Added the kill message module formats
1191 The affected file is irssi/src/silc/core/silc-channels.c.
1193 * The router did not save the channel mode the server announced.
1194 Affected file silcd/packet_receive.c.
1196 * Fixed a possible crash in INFO command in server. If the
1197 server did not provide the server info it crashed. Affected
1198 file silcd/command.c.
1200 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1202 * Fixed the GETKEY command in the server to check also the
1203 global list. Otherwise the GETKEY would not work correctly
1204 in normal SILC server. Affected file silcd/command.c.
1206 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1208 * Fixed GETKEY crash, it crashed if the command did not succseed.
1210 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1212 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1213 is now real and not just an macro interface to GMP.
1215 Removed the entire GMP from the source tree and imported new
1216 NSS MPI library instead. Reason for removing GMP is that it is
1217 extremely large and compiles extremely slow. The NSS MPI
1218 is only a few files and compiles in less than 10 seconds.
1219 The speed is also about the same as GMP. The MPI is imported
1220 to lib/silcmath/mpi.
1222 If the system has GMP installed we will still use the GMP.
1223 If it is not then the NSS MPI will be compiled.
1225 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1227 * Merged a long nickname (127 characters long) crash bugfix from
1228 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1230 * Merged a freed memory reference bugfix from Irssi CVS tree.
1231 Affected file irssi/src/core/commands.c.
1233 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1235 * Added the server's public key sving and verification to the
1236 server when performing the SKE. This was missing and the
1237 remote server's (or router's) public key was accepted without
1238 checking whether we have it previously or trust it at all.
1239 Affected file silcd/protocol.c.
1241 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1243 * Check in the silc_server_timeout_remote if protocol is active
1244 and make sure that the protocol's final callback is called so
1245 that all memory if freed. Affected file silcd/server.c.
1247 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1249 * silc_server_whois_send_reply crashed the server if the nickname
1250 was 127 characters long. Affected file silcd/command.c.
1252 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1254 * Added sanity check to the silc_server_new_client. If the hostname
1255 is provided inside username then check that the provided hostname
1256 really is the same as the resolved one. If the hostname was not
1257 resolved then check it from the public key. Affected file is
1258 silcd/packet_receive.c.
1260 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1261 if the server disconnected us and the connection is not valid
1262 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1264 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1265 the library to the lib/silcutil/silcutil.[ch].
1267 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1269 * Close log file after open. Affected file
1270 lib/silcutil/silclog.c.
1272 * Check whether sock == NULL in silc_client_send_packet and return
1273 if it is. Affected file lib/silcclient/silcclient.c.
1275 * Check rec->entry == NULL in the Irssi SILC Client before
1276 sending the channel message. Affecte file is
1277 irssi/src/silc/core/silc-servers.c.
1279 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1281 * Merged a splitted window bugfix from Irssi CVS tree. The
1282 affected file is irssi/src/fe-text/textbuffer-view.c.
1284 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1285 It did not print nickname.
1287 * Improved the distributions system a bit.
1289 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1291 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1292 irssi/src/fe-text/gui-window.c.
1294 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1295 to in-active server. The affected file is
1296 irssi/src/silc/core/client_ops.c.
1298 * Resolve the client in USERS command reply if the entry does
1299 not have username resolved. The affected file is
1300 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1301 command to WHOIS command to really resolve stuff. The USERS
1302 is not used any more in any critical section so WHOIS can
1303 be used even though it might be slower than IDENTIFY.
1305 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1308 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1310 * Changed the protocol API a bit more consistent in the
1311 lib/silccore/silcprotocol.[ch].
1313 * Changed the following headers to ROBODoc format:
1315 lib/silccore/silcpayload.h
1316 lib/silccore/silcprotocol.h
1317 lib/silccore/silcsockconn.h
1319 All core library headers are now formatted.
1321 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1323 * Fixed a bug in Irssi SILC client; do not show that you are
1324 server/router operator if you really are not. Affected file is
1325 irssi/src/silc/core/client_ops.c.
1327 * Renamed silc_command_free_payload to silc_command_payload_free.
1328 Affected file lib/silccore/silccommand.h
1330 * Added silcmath.h to include the prototoypes of various routines
1331 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1334 * Changed the following headers to ROBODoc format:
1336 lib/silccore/silcchannel.h
1337 lib/silccore/silccommand.h
1338 lib/silccore/silcid.h
1339 lib/silccore/silcidcache.h
1340 lib/silccore/silcmode.h
1341 lib/silccore/silcnotify.h
1342 lib/silccore/silcpacket.h
1343 lib/silcmath/silcmath.h
1345 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1347 * Added checking to the server code not to start the server if
1348 ciphers and stuff are not configured properly. Affected files
1349 silcd/serverconfig.[h] and silcd/server.c.
1351 * Changed the layout of the header files of the public interfaces
1352 in the SILC libraries. The new layout supports ROBODoc
1353 documentation tool (and some others) so that it is easy to create
1354 a library reference manual. All the other headers and source
1355 code must still follow the CodingStyle document. Also source
1356 code must not include these ROBODoc stuffs, only the headers.
1357 Furthermore, all public interface headers must now be named
1358 by using `silc' prefix, example: silcapi.h, silccipher.h.
1359 Some files were renamed due to this. All the other headers
1360 must not be used as public interfaces. I will update the
1361 CodingStyle document later. Changed following headers, so far:
1363 lib/silcclient/silcapi.h
1364 lib/silccore/silcauth.h
1365 lib/silccore/silcprivate.h
1366 lib/silccrypt/silcdh.h
1368 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1372 * Removed silc_client_packet_send_flush from the client library
1373 as it is not needed. Affected file lib/silcclient/client.[ch].
1375 * Added printing of message of unresolved authentication method
1376 to the Irssi SILC client. Added it to the module formats.
1377 Removed the same message from the client library.
1379 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1381 * Added new distribution feature, DISTLABEL. Every distribution
1382 can define own preprocessor label that can be used in the
1383 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1384 file distributions, acconfig.h.pre and prepare.
1386 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Added Makefile.defines_int to include the actual definitions
1389 for Makefile.defines.in. Tested the new distribution system,
1390 created distributions and tested installation.
1392 * Added AWAY message printing to the Irssi SILC client. Added
1393 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1395 * Added SCONNECT command to call the SILC's CONNECT command.
1396 Cannot use CONNECT directly since Irssi uses that internally.
1397 Affected file irssi/src/silc/core/silc-servers.c.
1399 Added ACTION local command. It is same as ME command but takes
1400 the channel as mandatory argument.
1402 Rewrote some of the Irssi's help files to suite for SILC
1405 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1407 * Added Makefile.defines[.in] that should for now on be included
1408 in all Makefile.am file in the source tree. That file includes
1409 all common compilation definitions for SILC source tree.
1411 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1413 * Minor changes to the ./prepare script to change the package
1414 name according the distribution name to the configure.in.
1416 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1418 * Created new distribution system. Added file `distributions'
1419 that defines all the distributions that can be created out of
1420 the SILC source tree. The ./prepare script now reads that
1421 file to determine how to prepare the distributions. The
1422 first argument to the ./prepare is the name of the distribution
1423 and second is the version of the distribution. If given
1424 without arguments it creates the default (toolkit) distribution
1425 with the default version (defined in ./prepare).
1427 All Makefile.am files that are subject to the distributions
1428 are now named as Makefile.am.pre. These are ./Makefile.am
1429 and lib/Makefile.am. Others may be changed later.
1431 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1433 * Added invite list, ban list, some key management and connection
1434 error message printing to module formats in the Irssi SILC client.
1436 * Added new silc_client_set_away_message to set the away message
1437 that is back to the person who sent private message. The
1438 affected file lib/silcclient/silcapi.h and the
1439 lib/silcclient/client_prvmsg.c.
1441 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1443 * Fixed the private message sending in the Irssi SILC client,
1444 added local command KEY to the Irssi SILC client.
1446 Added key management and key agreement message formats to the
1447 irssi/src/fe-common/silc/module-formats.[ch].
1449 Added USERS (alias WHO) printing, server/router operator
1450 indication and LIST command printing to the module formats.
1452 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1454 * Fixed channel joining notify handling, cumode notify handling
1455 from Irssi SILC client.
1457 * Added SILC specific module-formats to the Irssi SILC client so
1458 that SILC specific message hilighting, colors etc is possible.
1459 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1461 Added channel mode, channel user mode, actions, notices,
1462 whois and whowas printing to the the module-formats.c.
1464 * Fixed a bug in channel deletion in the server. The channel
1465 is not left to the cache even if the channel founder auth mode
1466 is set when there are no users anymore on the channel. Affected
1467 file silcd/server.c.
1469 * The silc_net_localhost now resolves the entire hostname including
1470 the domain name. Affected file lib/silcutil/silcnet.c.
1472 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1474 * Changed the ask_passphrase client operation to be ascynchronous.
1475 It has now a completion callback and a context that the
1476 application must call after it has got the passphrase from
1477 the user. Affected files lib/silcclient/silcapi.h,
1478 lib/silcclient/protocol.c, lib/silcclient/command.c and
1481 Added SilcAskPassphrase callback that the application calls
1482 to deliver the passphrase to the library.
1484 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1485 The public key verification and especially a certificate
1486 verification is asynchronous procedure.
1488 Added new SILC_SKE_STATUS_PENDING status to indicate the
1489 request is pending and a callback will be called to finalize
1492 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1493 indicate that remote end did not send its public key (or
1494 certificate), even though we require it. Added check for this
1495 condition in the SKE. This was a security bug, now fixed.
1497 Defined new SilcSKEVerifyCbCompletion callback that is called
1498 when the verification process is completed.
1500 The affected files lib/silcske/silcske_status.h and
1501 lib/silcske/silcske.[ch].
1503 * Changed the verify_public_key client operation to be async
1504 as well. Defined SilcVerifyPublicKey callback that is used to
1505 indicate the success of the public key verification process.
1507 Changed the server and client to use the new async client
1510 * Changed the Irssi SILC client's internal scheduler to be called
1511 twice as many times as it used to be. As a result the client
1512 should be a bit faster now. Affected file is
1513 irssi/src/silc/core/silc-core.c.
1515 * Added support to Irssi SILC client of asynchronous public key
1516 verification and passphrase inquiry. Affected file is
1517 irssi/src/silc/core/silc-core.c.
1519 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1521 * Do not say "You have left channel %s" in client library.
1522 Moved it to the application. Affected files are
1523 lib/silcclient/command.c and silc/client_ops.c.
1525 * Fixed silc_client_get_clients. Command context was not
1526 duplicated and was freed memory in the callback. Affected
1527 file lib/silcclient/idlist.c.
1529 * Do not say "you are now talking..." on JOIN command in the
1530 client library. The appliation must handle it.
1532 * Do not say ".. changed topic to" in command reply in the
1533 client libary. The application must handle it.
1535 * Fixed TOPIC command sending in the client library.
1537 * Fixed a memory leak in silc_client_command_free in the file
1538 lib/silcclient/command.c.
1540 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1542 * Imported a modified version of Irssi client to the source tree.
1543 The Irssi will be used to create a new client called
1544 Irssi SILC. Imported to irssi/.
1546 Added silc_core_init_finish function to the Irssi. Affected
1547 file irssi/configure.in.
1549 A lot changes in the Makefile.ams around the irssi tree.
1551 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1553 * Do not rehash if the new size is same as the old size of the
1554 hash table, in the silc_hash_table_rehash*. The affected file
1555 lib/silcutil/silchashtable.c.
1557 * Replaced hash_table_del_by_context calls from the server
1558 (when channel->user_list and client->channels) to the
1559 hash_table_del as it is sufficient and faster.
1561 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1563 * Added silc_hash_table_list, silc_hash_table_get and the
1564 SilcHashTableList structure to provide an alternative way to
1565 traverse the hash table. The affected files are
1566 lib/silcutil/silchashtable.[ch].
1568 * Changed the server's idlist routines to use the hash table
1569 routines to optimize the code.
1571 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1573 * Replaced the client entry's `channel' list and channel entry's
1574 `user_list' list to hash tables for optimized lookup. Changed
1575 the code to use the hash table interface around the code.
1576 Affected file lib/silcd/idlist.[ch].
1578 * Added `auto_rehash' boolean argument to the function
1579 silc_hash_table_alloc to indicate whether the hash table should
1580 auto-rehash when it thinks is appropriate time. It will
1581 increase the hash table size if the there is twice as much
1582 entries in the table than the size of the table, and will
1583 decrease the size if there are twice as less entries than
1584 the size of the table.
1586 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1588 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1590 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1592 * silc_idcache_purge_by_context deletes the entry now by context
1593 as it is supposed to do. Affected file lib/silccore/idcache.c.
1595 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1596 client is not anymore valid (WHOWAS givens the info) and not
1597 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1599 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1601 * Removed the `data' and `data_len' arguments from the ID Cache
1602 interfaces and added `name' argument. ID Cache does not handle
1603 anymore the binary data only a names associated with given ID.
1605 * When hashing a Client ID with silc_hash_id the entire ID is
1606 not hashed anymore, instead only the hash of the Client ID is
1607 hashed. This way we can access the Client ID from the cache
1608 with Client ID but with the hash of the ID (which is a hash of
1609 the nickname) as well without any difference in performance.
1611 Added also silc_idcache_find_by_id_one_ext to do one on one
1612 searching when we have the actual ID. Added also function
1613 silc_hash_client_id_compare. The affected files are
1614 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1616 * When hashing the name associated with a ID it is always done
1617 in lowercase. This way we can access the cache without worrying
1618 about case-sensitivity, even though, for example nicknames are
1621 * Fixed a bug in server with channel message sending. It put
1622 wrong ID type as destination ID. The affected file
1623 silcd/packet_send.c.
1625 * silc_idcache_del_by_context now deletes from all hash tables
1626 by context. Affected file lib/silccore/idcache.c.
1628 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1630 * Changed the client library to use the new ID Cache interface.
1631 Changes around the source tree.
1633 * Added silc_hash_table_rehash_ext to rehash with specific
1634 hash function. Affected file lib/silcutil/silchashtable.[ch].
1636 * Added silc_hash_string_compare to compare two strings in the
1637 hash table. Affected file lib/silcutil/silcutil.[ch].
1639 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1641 * Added new function silc_idcache_del_by_context into the
1642 lib/silccore/idcache.[ch].
1644 * Changed the server's ID list routines to use the new ID Cache
1645 interface. Changes around the source tree.
1647 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1649 * Added silc_hash_table_del[_by_context]_ext functions in to the
1650 lib/silcutil/silchashtable.[ch].
1652 Removed silc_hash_table_find_all* routines and added new
1653 silc_hash_table_find_foreach to replace them.
1655 Added silc_hash_table_replace_ext function as extended
1656 replacing function. Separated the simple hash table interface
1657 from the extended hash table interface in the file
1658 lib/silcutil/silchashtable.h.
1660 * Fixed minor bugs and changed it to use some of the new
1661 hash table functions in lib/silccore/idcache.c
1663 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1665 * Added new function silc_hash_table_find_all to return all keys
1666 in the hash table by the specified key. As the hash table is
1667 collision resistant it also makes it possible to have several
1668 duplicate keys in the hash table. This function may be used to
1669 find all of the keys from the hash.
1671 Added user_context arguments to the SilcHashFunction,
1672 SilcHashCompare and SilcHashDestructor to deliver user specified
1675 Added new fuctions silc_hash_table_find[_all]_ext to do
1676 extended lookup with specified hash and compare functions and
1677 specified user contexts.
1679 Added new function silc_hash_table_add_ext to add the key
1680 with specified hash function and user context.
1682 Added new function silc_hash_table_foreach to traverse all
1683 entrys in the hash table. Added SilcHashForeach callback
1686 Added new function silc_hash_table_del_by_context to delete
1687 the entry only if the context associated with the key matches.
1689 Affected files are lib/silcutil/silchashtable.[ch].
1691 * Removed silc_hash_[server/client/channel]_id and added just
1692 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1693 silc_hash_id_compare to compare two ID's using as the hash table
1694 comparison function. Added also silc_hash_data to hash
1695 binary data and silc_hash_data_compare to compare it.
1697 * Removed silc_idlist_find_client_by_hash as it is not needed
1698 anymore. Affected file silcd/idlist.[ch].
1700 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1701 to use internally the SilcHashTable. The new ID Cache is a lot
1702 faster than the old one. Some of the ID Cache interface was also
1703 rewritten and obsolete and stupid functions were removed.
1705 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1707 * Added entry_count field to the SilcHashTable to keep the number
1708 of the entries in the table. Implemented the function
1709 silc_hash_table_rehash. Added new function
1710 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1712 Fixed a minor bug in silc_hash_table_free.
1714 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1715 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1716 into the lib/silcutil/silcutil.[ch].
1718 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1720 * Implemented a collision resistant hash table into the
1721 lib/silcutil/silchashtable[ch]. See the header and the source
1722 for the SilcHashTable API.
1724 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1726 * Merged dotconf version 1.0.2 into lib/dotconf.
1728 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1730 * Do not compile anything in lib/silcsim/* if the SIM support
1731 is not enabled. The tree should now compile without problems
1734 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1736 * Compiled the SILC under cygwin. Compiled and tested briefly
1737 without problems. More tests needed. The SIMs didn't compile
1740 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1742 * Fixed possible crash in silc_get_username in the
1743 lib/silcutil/silcutil.c.
1745 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1747 * Fixed a va_arg in silc/client_ops.c.
1749 * Oops, RC5 routines were named AES and caused some problems
1750 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1752 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1754 * Added new SilcIDIP structure into the lib/silccore/id.h and
1755 replaced the old `ip' fields from all SILC ID's to that type.
1756 This is a step towards IPv6 support.
1758 The silc_id_get_len takes now the ID as an extra argument.
1759 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1760 both IPv4 and IPv6 based ID's.
1762 The affected files are lib/silccore/id.[ch] and other files
1763 around the tree using these routines.
1765 * Removed the ID length arguments in server from various
1766 silc_server_send_notify_* routines -> they are not needed
1769 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1771 * Fixed memory leak in silc_encode_pem_file in the file
1772 lib/silcutil/silcutil.c.
1774 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * Check minor version as well in the SKE. Affected files are
1777 silcd/protocol.c and lib/silcclient/protocol.c.
1779 * Added --identifier option to the server so that an identifier
1780 can be when creating the public key for the server. Affected
1781 file is silcd/silcd.c.
1783 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1784 lib/silccrypt/silcpkcs.c.
1786 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1788 * Register default ciphers and stuff when using -C option with
1789 the server. Affected file sildc/silcd.c.
1791 * Put back the servers public key filename format, it is better
1792 than the new one. For now, the client keys are saved with the
1793 new filename format. The affected file silc/client_ops.c.
1795 * Implemented the Cipher API for the rest of the ciphers that
1796 did not implement it or implemented it the wrong way.
1798 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1800 * Register default ciphers and stuff when using the -S option
1801 in the client. Affected file silc/silc.c. Same also when
1802 creating new key pair with -C option.
1804 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1806 * Fixed the silc_verify_public_key client operation function to
1807 save the public keys differently. The fingerprint is now
1808 used as filename and not the hostname. This way also the
1809 client keys are saved uniquely and not with hostnames. The
1810 affected file is silc/client_ops.c.
1812 * Trimmed the silc_hash_fingerprint function to remove extra
1813 whitespaces from the end of the fingerprint. The affected
1814 file is lib/silccrypt/silchash.c.
1818 * Added silc_cipher_register_default function to register all
1819 default ciphers. It can be used when configuration files
1820 does not exist and the application does not want any specific
1821 ciphers in any specific order.
1823 The SilcDList is now used as silc_cipher_list dynamically
1824 allocated cipher list. Removed the static list all together
1825 and now all ciphers must be allocated to the dynamic list.
1826 The silc_cipher_alloc routine was changed to check only the
1829 All silc_cipher_* routines that used to return int returns
1832 The affected files lib/silccrypt/silccrypt.[ch].
1834 * The same thing was done to silc_hash_* as for silc_cipher_*
1835 routines. Affected files lib/silccrypt/silchash.[ch].
1837 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1838 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1839 Added also silc_pkcs_[un]register[_default] functions.
1840 Removed the data_context from the PKCS API.
1842 * Added silc_hmac_register_default function to register default
1843 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1844 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1845 to unregister all hmacs at once.
1847 * Register the default ciphers, hash functions, PKCSs and HMACs
1848 if client's configuration file does not exist. The affected
1851 * The client did not load the hash functions from the SIM
1852 modules at all. Added support for this. Affected file is
1853 silc/clientconfig.c.
1855 * When decoding public key with silc_pkcs_public_key_decode, check
1856 the supported algorithm only if PKCS are registered. Affected
1857 file lib/silccrypt/silcpkcs.c. The same was done with the
1858 silc_pkcs_private_key_decode.
1860 * Fixed the SILC List routines to keep the list always in order.
1861 It used to change the list's order when traversing the list but
1862 not it preserves the order. Affected file lib/trq/silclist.h.
1864 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1866 * Added the client library to use the SilcSocketConnection's
1867 reference counter (by silc_socket_dup) to prevent the bug that
1868 the socket object may be freed underneath async operation.
1870 * The name resolv library checking fixes in the configure.in.pre.
1873 * Created new version of the protocol drafts for future
1874 development. The -03 drafts are the ones that will be changed
1875 in the trunk now and the -02 will remain as they are.
1877 * Send list of CUMODE notifys to the router when announcing
1878 the channel users to the router. Affected file silcd/server.c.
1879 If the router receiving channel founder CUMODE for a channel
1880 that already has channel founder it will send CUMODE notify
1881 to the sender to remove the channel founder rights from the
1882 announced client. Affected file silcd/packet_receive.c.
1884 * The CUMODE notify may now use Server ID as well as the entity
1885 who changes the mode. Updated protocool specs.
1887 * Updated INSTALL and README files.
1889 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1891 * New web pages in the http://silc.pspt.fi. The pages was
1896 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1898 * Implemented the [DenyConnectin] config section in the server.
1899 Added silc_server_config_denied_conn to check whether incoming
1900 connection is denied. Affected file silcd/serverconfig.[ch].
1902 * Do not check the ports when checking the incoming configuration
1903 data if the port is 0, meaning any. Affected file is
1904 silcd/serverconfig.c.
1906 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1908 * Fixed buffer overflow in silc_string_compare in the file
1909 lib/silcutil/silcutil.c.
1911 * Fixed double free in silc_server_command_leave in the file
1914 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1916 * Fixed the version checking in the server. Affected file is
1919 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1921 * Fixed the configuration data fetching when accepting new
1922 connections in the server. Affected file silcd/server.c.
1924 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1926 * Added `sender_entry' argument to the function
1927 silc_server_packet_relay_to_channel so that we can check
1928 whether some destination actually belongs to the same route
1929 the sender belongs (ie, we must not resend the packet to the
1930 sender). Affected file silcd/packet_send.[ch].
1932 * Added `servername' field to the SilcClientEntry in the server
1933 to hold the name of the server where client is from. Affected
1934 file is silcd/idlist.h.
1936 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1938 * Moved the channel message encrypting in the router betwen
1939 router connections from silc_server_channel_message to the
1940 silc_server_packet_relay_to_channel since we want to check
1941 whether we have anybody channel before encrypting anything.
1942 Affected files silcd/packet_[receive/send].c.
1944 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1946 * Fixed the [AdminConnection] server config section to support
1947 multiple entries. Affected file silcd/serverconfig.c.
1949 * Added support into the server to check the validity of the
1950 incoming connection before executing any KE or authentication
1953 * The connection configuration is now saved to the KE and
1954 connection auth protocol contexts and not fetched anymore in
1955 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1957 * The local hosts listenning address and port is also resolved
1958 now when starting the server. We want to have the socket object
1959 to include the real address and port for the listener. Added
1960 new function silc_net_check_local_by_sock into the files
1961 lib/silcutil/silcnet.[ch].
1963 * Fixed a broadcast bug in server -> do not broadcast if we
1966 * Fixed a routing bug. Do not route broadcast packets ever.
1967 Broadcast packets must be processed always and not routed since
1968 they may be destined to some other host than yourself and thus
1969 would get routed without no good reason. Affected file is
1972 * Added function silc_server_config_is_primary_route to check
1973 whether primary router connection has been configured (a router
1974 configuration that we are initiating). If there is not, we
1975 will assume that there is only two routers in the SILC network
1976 and we will use the incoming router connection as our primary
1977 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1979 * Changed the order of the broadcasting. Broadcast _after_ the
1980 packet has been processed not before. Affected file is
1983 * Fixed a [ClientConnection] parsing bug. The port was never
1984 parsed correctly thus resulting to port 0. Affected file
1985 silcd/serverconfig.c.
1987 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1988 argument and did not set the broadcast packet flag. Affected
1989 file silcd/packet_send.c. Fixed same bug in the function
1990 silc_server_send_notify as well.
1992 * If we receive NEW_ID packet for our own ID in the server, ignore
1995 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1999 * Removed the nickname from the Private Message Payload.
2000 Updated the code and the protocol specs.
2002 * Updated protocol specs for submitting to the IETF.
2004 * Tweaked the Random Number Generator a bit. Affected file
2005 lib/silccrypt/silcrng.c. Exported a new function
2006 silc_rng_[global]_add_noise which can be used to add more
2009 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2011 * Do not parse packets with different timeout when protocol
2012 is active -> may cause problem with rekey. Affected file
2015 * When server receives signoff notify it must not create
2016 new channel key if the client is on any channels since the
2017 sender of the signoff notify will create it.
2019 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2021 * Added printing of error messages during SKE protocol from the
2022 failure packet sent by server during SKE. Affected file
2025 * Removed the client's failure_callback handling with timeout
2026 and handle it immediately when received.
2028 * The SKE library returned wrong type in SUCCESS and FAILURE
2029 packets. They must be 32 bit MSB not 16 bit MSB.
2031 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2033 * Ok, rewrote the logic of the re-key and now it seems to work.
2034 I tested it on high traffic with frequent re-keys without
2035 problems. Added hmac_receive (and renamed hmac to hmac_send)
2036 in SilcClientConnection in lib/silcclient/client.h and
2037 in SilcIDListData in silcd/idlist.h. Also, removed the
2038 SilcPacketParserContext's cipher and hmac fields as they are
2039 not needed anymore and actually caused some problems when
2040 the ciphers and hmac's changed underneath the packet parser.
2042 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2044 * If re-key protocol is active then process the incoming packets
2045 synchronously since we must assure that icoming packets encrypted
2046 with the old key is processed before the new keys is set to
2047 use. This is true other packets than for REKEY packets.
2048 Affected file silcd/server.c. The same was done to client library
2049 as well, affected file lib/silcclient/client.c.
2051 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2053 * Fixed bug in client and server to accept the force send if
2054 the packet is send from silc_[server/client]_packet_process
2055 function. Otherwise the packets are never delivered, oops.
2057 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2059 * Disable force sending of packets when REKEY protocol is active.
2060 We must assure that no packet is sent directly when rekey is
2061 performed. All packets must be sent through packet queue.
2062 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2063 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2064 function is silc_[server/client]_packet_send_real to check
2067 * Replaced the SIM paths from example config files to
2068 /usr/local/modules. Also, make install creates now
2069 /usr/local/silc/logs directory to hold all the SILC server
2072 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2074 * Made the configure.in.pre work on Solaris. Patch by salo.
2076 * Made all ciphers compatible with non-x86 machines. Defined
2077 CBC mode macros into lib/silccrypt/ciphers_def.h.
2079 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2081 * Fixed the make install.
2083 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2085 * When MAC computation fails the silc_packet_decrypt returned 0
2086 even though it was supposed to return -1. Fixed this. The
2087 affected file is lib/silccore/silcpacket.c.
2089 * Do not replace the config files in /etc/silc (in make install)
2090 if they already exist. Affected file ./Makefile.am.
2092 * Do not send re-key packets immediately but through packet queue.
2093 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2095 * Changed silc_net_check_host_by_sock to return FALSE if the
2096 IP/DNS could not be resolved. Though, it returns the IP address
2097 now even if it could not resolve it (but returns also FALSE).
2098 Affected file lib/silcutil/silcnet.[ch].
2100 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2102 * Added silc_pkcs_decode_identifier to decode the public key's
2103 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2104 Added also silc_pkcs_free_identifier. Added also new context
2105 SilcPublicKeyIdentifier.
2107 * Added -S option to the silc client. It is used to dump the
2108 contents of the specified public key file.
2110 * Changed the PKCS api to return the public key length when
2111 setting the public key.
2113 * Fixed a fatal bug in the public and private key file loading.
2114 Affected file lib/silccrypt/silcpkcs.c.
2116 * Execute the packet parsing for client with zero (0) timeout
2117 if the protocol is active. Affected file silcd/server.c.
2119 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2121 * Made the key generation options to the silcd program. Added
2122 -C option, equivalent to client's option.
2124 * Added new [ServerKeys] config section to the server. It
2125 configures the server's public and private key.
2127 * Defined generic Public Key Payload into the protocol
2128 specification to send specific type of public keys and
2131 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2132 public key or certificate.
2134 * Implemented the GETKEY command to the server and to the
2135 client library and on user interface.
2137 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2139 * Made preliminary `make install' work.
2141 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2143 * Added SilcServerRekey context into silcd/idlist.h.
2145 * Added the PFS support as defined in the specification to the
2146 SKE protocol. Affected files lib/silcske/*.c.
2148 * Added `ske_group' field to the SilcServerRekey context to hold
2149 the number of the SKE group that is used with PFS in re-key.
2150 Affected file silcd/idlist.h.
2152 * Added PFS re-key support to the server. Affected file is
2155 * Added silc_protocol_cancel to cancel execution of the next
2156 state of the protocol. Affected file is
2157 lib/silccore/silcprotocol.[ch].
2159 * Added the re-key support with and without PFS to the client
2160 library. Re-key is performed once in an hour, by default.
2162 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2163 Added silc_client_rekey_callback and silc_client_rekey_final.
2164 Affected files are lib/silcclient/protocol.[ch] and
2165 lib/silcclient/client.[ch].
2167 * Removed the `hmac_key' and `hmac_key_len' fields from the
2168 SilcClientConnection structure; not needed. Affected file is
2169 lib/silcclient/client.h.
2173 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2175 * Do not ask whether user wants to use the negotiated private key
2176 for private messages, just use it. Affected file is
2177 silc/local_command.c.
2179 * Added `send_enc_key' and `enc_key_len' fields to the
2180 SilcIDListData structure since they are needed in the re-key
2181 phase. Affected file is silcd/idlist.[ch].
2183 * Implemented the simple re-key protocol into the server.
2184 Affected files silcd/server.c and silcd/protocol.[ch]. The
2185 re-key will be performed once in an hour, by default.
2187 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2188 Added silc_server_rekey, silc_server_rekey_callback and
2189 silc_server_rekey_final.
2191 * Removed Tunneled flag from the protocol. Updated the code
2192 and the specifications.
2194 * Adde `pfs' field to the SilcIDListData to indicate whether
2195 the PFS is to be performed in the re-key. Affected file is
2198 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2200 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2201 int64 of at least the xintXX size. If void * is less that 4
2202 bytes uint32 * will be used. Defined bool as boolean.
2204 * Changed _ALL_ unsigned long and unsigned int to uint32,
2205 unsgined short to uint16 in the source tree.
2207 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2208 not handle clients that has entry->data.registered == FALSE.
2209 They are not in the network anymore. Affected file is
2212 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2214 * Implemented the sending of the SERVER_SIGNOFF notify in the
2215 server. Affected file is silcd/server.c.
2217 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2218 Added also silc_notify_payload_encode_args into the
2219 lib/silccore/silcnotify.[ch].
2221 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2222 Affected file silcd/packet_receive.c.
2224 * Implemented the SERVER_SIGNOFF notify handling in the client
2225 library. Affected file lib/silcclient/client_notify.c. Also,
2226 implemnted the printing of the SERVER_SIGNOFF info to the
2227 application. Affected file silc/client_ops.c.
2229 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2230 if the deleting was successful. Affected file silcd/idlist.[ch].
2232 * Added support for public key authentication in the connection
2233 authentication protocol in the client library. Affected file
2234 lib/silcclient/protocol.c.
2236 * Changed the server's silc_idlist_get_clients_by_* interface
2237 to support already allocated array so that new entries may be
2238 added to pre-allocated array. Affected file silcd/idlist.[ch].
2239 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2240 and command replies.
2242 * All command reply functions in the server now calls the
2243 pending command callback even if error occured. This way the
2244 error will be delivered to the client as well. Affected files
2245 silcd/command.c and silcd/command_reply.c.
2247 * Fixed INFO command to return local server's info if no server
2248 was provided. Affected file lib/silcclient/command.c.
2250 * Removed RESTART command for good. Updated the code and the
2253 * Rewrote parts of the task system. It is a bit simpler now.
2254 Removed unsued task priorities. The affected files are
2255 lib/silcutil/silctask.[ch].
2257 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2259 * Moved the USERS printing from the library to the application.
2260 Affected files lib/silcclient/command.c and silc/client_ops.c.
2262 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2266 * Added channel key re-key support. The re-key is perfomed
2267 only by the router and is done once in an hour. Added `rekey'
2268 field to the SilcChannelEntry in the server. Affected files
2269 silcd/server.c and silcd/idlist.h.
2271 * Added silc_task_unregister_by_context into the file
2272 lib/silcutil/silctask.[ch].
2274 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2276 * Added SILC_UMODE_GONE mode to indicate when the client is not
2277 present in the SILC network. Added also support to the local
2278 command AWAY that will set this mode. Added support of showing
2279 "xxx is gone" in WHOIS command. The USERS command shows the
2280 gone status as well.
2282 * Fixed setting server and router operator privileges in the
2283 server's UMODE command. Affected file silcd/command.c.
2285 * Merged the SKE KE1 and KE2 payloads into one payload. The
2286 new KE payload is equivalent to the old KE2 payload.
2288 Cleaned up the SKE Start Payload parsing. It now uses the
2289 simple buffer unformatting to do the parsing. A lot faster
2292 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2293 to the SKE that is used to indicate whether both of the SKE
2294 parties should perform authentication. By default only the
2295 responder performs authentication. By setting this flag also
2296 the initiator must do authentication. By default it is unset
2297 since in normal SKE case, client to server connection, only
2298 the responder should do authentication. When doing SKE between
2299 two clients both should perform authentication. Updated the
2300 code and the protocol specs.
2302 * A little fix to IDENTIFY command in the server. Search the
2303 client first by hash not nickname. Affected file is
2306 * Fixed the silc_client_close_connection to support closing
2307 the client to client connections wihtout deleting too much
2308 data. Affected file lib/silcclient/client.c.
2310 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2311 are received if protocol used to be active but is not anymore
2312 the application would crash due to NULL pointer dereference.
2313 Affected files silcd/server.c and lib/silcclient/client.c.
2315 * Added `hash' field to the SilcClientConnection to include
2316 the hash function negotiated in the SKE protocol.
2318 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2319 to set the channel founder authentication data. A client can
2320 claim the founder rights later by providing the authentication
2321 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2322 This way the channel founder can regain the channel founder
2323 privileges even it is left the channel. This works only on
2324 local server and the client must be connected to the same
2325 server to be able to regain the founder rights. Updated the
2326 protocol specs accordingly.
2328 Added support to the CMODE command in the client to set the
2329 founder auth data. Read the README to see how to set it.
2331 Added support to the CUMODE command to claim the founder
2332 rights. Read the README to see how to do it.
2334 Added support for the founder authentication to the Channel
2335 Entry in the server. Affected file silcd/idlist.h.
2337 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2338 server's CMODE command. Affected file silcd/command.c.
2340 * Added the following new functions into lib/silccore/silcauth.[ch]:
2341 silc_auth_get_method and silc_auth_get_data.
2343 * The server now saves the remote hosts public key to the
2344 SilcIDListData pointer. Affected file silcd/protocol.c.
2346 * The normal server now does not remove the channel entry from
2347 the cache if the founder authentication data is set. It used
2348 to remove it if the founder was the last one on the channel on
2349 the server and left the channel. The auth data is saved and
2350 if the channel is re-joined later the old entry is used with
2351 the old auth data. Affected files silcd/command_reply.c and
2354 * Removed the `pkcs' field from the SilcIDListData structure
2355 in the server; it is not used. Affected file silcd/idlist.h.
2357 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2359 * Fixed packet processing on slow links. Partial packets were
2360 never re-processed because the incoming data buffer was cleared
2361 by the application. Application must not directly clear the
2362 sock->inbuf, the packet processing routines handle it. Fixed
2363 this in client library and in server.
2365 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2367 * Fixed the WHOIS and IDENTIFY send reply function to really
2368 check whether to send list or just one entry. Affected file
2371 * Cleaned up the LEAVE command's channel key distribution. The
2372 affected file silcd/command.c.
2374 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2375 can enforce the channel mode as well. In that case the ID
2376 includes the ID of the server. The code now enforces the
2377 mode change if the router have different mode than the server.
2379 * The notify client operation with CMODE_CHANGE notify can now
2380 return NULL client_entry pointer if the CMODE was not changed
2381 by client. Application must check for this.
2383 * Added <Server ID> argument to INFO command to support server
2384 info fetching by Server ID.
2386 * Added silc_server_announce_get_channel_users to get assembled
2387 packets of channel users of the specified channel. Affected
2388 file silcd/server.[ch].
2390 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2391 was freed underneath the ID Cache.
2393 * Re-announce clients when the server received CHANNEL_CHANGE
2394 notify from the router. Affected file silcd/packet_send.c.
2396 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2398 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2399 crashed since it did not handle the fact that there is no cipher
2400 called "3" and didn't check the error condition. Now fixed.
2402 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2403 flag. It can be used to send message requests.
2405 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2407 * Implemented the RESTART command in the client.
2409 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2410 notice type messages. Added notice printing to the user
2413 * The channel keys are not re-generated if the channel's mode
2414 is PRIVKEY, ie private key on the channel exists. Affected
2415 files silcd/server.c and silcd/command.c.
2417 * Fixed a little bug in channel message delivery when channel
2418 private keys are set in the server. Affected file is
2419 silcd/packet_send.c.
2421 * Changed the setting on channel->on_channel = TRUE from the
2422 silc_client_save_channel_key to the JOIN command reply. The
2423 key payload is not received if the private channel key is set.
2424 Affected file lib/silcclient/command_reply.c and the
2425 lib/silcclient/client_channel.c.
2427 * When the CMODE_CHANGE notify is sent and the channel private
2428 key mode is removed the channel key must be re-generated in
2429 other cells as well. Added this support for the router in the
2430 silcd/packet_receive.c.
2432 * Added new local command NOTICE to send notice message on
2433 channel. Affected file silc/local_command.[ch].
2435 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2437 * Added new local command ME to the client. It is used to send
2438 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2439 some action. Affected file silc/local_command.[ch].
2441 * Changed channel_message and private_message client operations
2442 to deliver the message flags to the application. Added also
2443 the `flags' arguments to the silc_client_send_channel_message
2444 and silc_client_send_private_message functions. Affected file
2447 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2449 * Redefined the Private Message Payload to support private message
2450 keys and to support the new private message flags. Updated
2451 the protocol specs. Flags makes it possible to have for example
2452 CTCP style messages.
2454 * Added new type SilcPrivateMessagePayload and defined an API
2455 for it in the lib/silcclient/silcprivate.[ch].
2457 * Tested private message private keys successfully. Tested the
2458 private message key set, unset and list commands with the new
2461 * Redefined the Channel Message Payload to include the channel
2462 message flags (equal with private message flags) to support
2463 for example CTCP style messages.
2465 * Defined some of the message (for channel and private message)
2466 flags. Updated the protocol specs and added the flags to the
2467 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2469 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2471 * Added SilcKeyAgreementStatus type to the key agreement routines
2472 to indicate the current status and error if one occured.
2473 The status types are defined in the lib/silcclient/silcapi.h.
2475 * Added new local command KEY that is used to set and unset private
2476 keys for channels, set and unset private keys for private messages
2477 with remote clients and to send key agreement requests and
2478 negotiate the key agreement protocol with remote client. The
2479 key agreement is supported only to negotiate private message keys,
2480 it currently cannot be used to negotiate private keys for channels,
2481 as it is not convenient for that purpose.
2483 * Fixed a minor pending callback setting bug in the function
2484 silc_client_get_client_by_id_resolve, now the function works.
2485 Affected file lib/silcclient/idlist.c.
2487 * Added function silc_net_get_local_port to get local bound
2488 port by socket. Added to lib/silcutil/silcnet.[ch].
2490 * Added `sockets' and `sockets_count' fields to the SilcClient
2491 object. They hold the sockets of the listenning sockets in
2492 the client. Listenning sockets may be for example the key
2493 agreement server. Affected file lib/silcclient/client.[ch].
2494 Added functions the silc_client_add_socket and the
2495 silc_client_del_socket. They are exported to the application
2498 * Added ~./silc/clientkeys to support other client's public keys.
2500 * Renamed verify_server_key client operation to verify_public_key
2501 and added one argument to indicate the type of the connection
2502 (server, client etc.).
2504 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * Added silc_server_connection_auth_request to handle the
2507 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2508 silcd/packet_receive.[ch].
2510 * Added silc_server_send_connection_auth_request into the
2511 silcd/packet_send.c to send the connection auth request packet.
2513 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2516 * Fixed the public key authentication in responder side in the
2517 server. The `auth_data' pointer includes the SilcPublicKey
2518 not the path to the public key. Affected file silcd/protocol.c.
2520 * Implemented the public key authentication in the initiator side
2521 in the server. Affected file silcd/protocol.c.
2523 * Removed the [RedirectClient] config section from the server
2524 configuration. Is not needed and I don't want to implement it.
2526 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2528 * Cleaned up the CMODE command in the server. It now works
2529 correctly and supports all the modes defined in the protocol.
2530 Affected file is silcd/command.c.
2532 * Added `hmac_name' field to the SilcChannelEntry in the server
2533 to hold the default HMAC of the channel. It can be set when
2534 creating the channel (with JOIN command). Affected files
2537 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2538 type to indicate the change of the current cipher and hmac
2539 on the channel. Client can safely ignore the <cipher> argument
2540 (if it chooses to do so) since the CHANNEL_KEY packet will
2541 force the channel key change anyway. The <hmac> argument is
2542 important since the client is responsible of setting the new
2543 HMAC and the hmac key into use.
2545 * Fixed the CMODE command in the client library as well.
2547 * Tested CMODE command in router environment successfully.
2549 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2551 * Show the version of the remote client (or server) when connecting
2552 to the server. It is logged to the log file. Affected file
2553 is silcd/protocol.c.
2555 * Fixed the KILLED notify handling in the client library. The
2556 client must be removed from all channels when receiving the
2559 Also, do not remove the client entry when giving the KILL
2560 command but when the KILLED notify is received.
2562 * Removed silc_idlist_find_client_by_nickname from the server.
2563 Not needed anymore. Affected files silcd/idlist.[ch].
2565 * Implemented the CHANNEL_CHANGE notify type handling to the
2566 server. Affected file silcd/server.c.
2570 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2572 * Added silc_server_send_notify_invite to send the INVITE
2573 notify between routers.
2575 * Implemented the INVITE command correctly to the server.
2577 * Implemented the INVITE notify type handling in the server.
2579 * Implemented the INVITE command to the client library and on the
2582 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2584 * Added function silc_server_get_client_resolve to find the
2585 client entry by ID from all ID lists and then resolve it
2586 (using WHOIS) if it cannot be found. Affected file is
2589 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Implemented the BAN command to the client library.
2593 * The JOIN command in the server now checks the invite list
2596 * Changed the silc_command_reply_payload_encode_va and the
2597 silc_command_payload_encode_va to support that if argument is
2598 NULL it ignores and checks the next argument. Affected file
2599 lib/silccore/silccommand.c.
2601 * Added silc_server_send_notify_ban to send the BAN notify
2602 type between routers.
2604 * Chaned the silc_notify_payload_encode to support that if
2605 argument is NULL it ignores and checks the next argument.
2606 Affected file lib/silccore/silcnotify.c.
2608 * Tested ban lists in router environment successfully.
2610 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2612 * Implemented BAN command to the server, in silcd/command.[ch].
2614 * Removed the BAN and INVITE_LIST modes from the CMODE command
2617 * Added function silc_string_match to regex match two strings.
2618 Affected files lib/silcutil/silcutil.[ch].
2620 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2622 * Redefined parts of the SilcChannelEntry in the server to support
2623 the new ban and invite lists.
2625 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2627 * Redefined the INVITE command. The same command can be used to
2628 invite individuals to the channel but also to manage the invite
2629 list of the channel (to add to and remove from the invite list).
2630 Updated the protocol specs.
2632 * Added new command SILC_COMMAND_BAN that can be used to manage
2633 the ban list of the channel. Updated the protocol specs.
2635 * Removed the channel modes: the SILC_CMODE_BAN and the
2636 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2637 in the CMODE command. The equivalent features are now available
2638 using INVITE and BAN commands. Updated the protocol specs.
2640 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2641 in the network about change in the current ban list. The notify
2642 type is not used by the client.
2644 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2645 support the invite lists.
2647 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2649 * Added new function silc_string_regexify that converts string
2650 including wildcard characters into regex string that can
2651 be used by the GNU regex library. Added into the file
2652 lib/silcutil/silcutil.[ch].
2654 Added silc_string_regex_combine to combine to regex strings
2655 into one so that they can be used as one regex string by
2656 the GNU regex library. Added into the file
2657 lib/silcutil/silcutil.[ch].
2659 Added silc_string_regex_match to match two strings. It returns
2660 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2662 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * Imported GNU regex to the soruce tree into lib/contrib.
2665 Fixed some compiler warning from the regex.c.
2667 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Fixed MOTD command in the server to work in router environment.
2671 * Fixed the MOTD command in the client library to support
2672 the server argument in the command.
2674 * Added `nickname_len' argument to the silc_idlist_add_client
2675 in the server, as the `nickname' argument may be binary data
2678 * Added silc_idlist_get_channels to return all channels from
2681 * Implemented LIST command to the server. Affected file is
2684 * Implemented the LIST command to the client library and on the
2687 * Added [<user count>] argument to the LIST command reply.
2688 With private channels the user count is not shown.
2690 * Updated TODO and README.
2692 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2694 * The client entry's data.registered must be TRUE even with
2695 global client entry on global client list. The data.registered
2696 is used to check whether the client is anymore in the network,
2697 for example with WHOWAS command so it must be valid.
2699 * Fixed the WHOWAS command in the server. It now actually works
2700 in router environment. Added function into silcd/command_reply.c
2701 silc_server_command_reply_whowas_save.
2703 * Added silc_idlist_purge function to the silcd/idlist.c
2704 to periodically purge the ID Cache.
2706 * Fixed INFO command in the server. It works now in router
2707 environment. Added <server name> argument to the INFO command
2708 reply. Updated the protocol specs.
2710 * Fixed minor bug in silc_idcache_purge to not purge if the
2711 expire value is zero.
2713 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2714 they were buggy because of the WHOWAS information.
2716 * Fixed local command MSG to handle the async resolving of
2717 the remote client properly. It used to fail the first MSG.
2718 Affected file silc/local_command.c.
2720 * Added `data_len' field to SilcIDCache context.
2722 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2724 * Update TODO. Todo in commands in the server.
2726 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2729 used by routers as broadcast packet to inform other routers
2730 about the changed user mode.
2732 Implemented the notify handling in the server. Affected file is
2733 silcd/packet_receive.c. Added the function
2734 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2736 * Added new generic Channel Payload and deprecated the New Channel
2737 Payload. The New Channel Payload is now the generic Channel
2740 * Added new argument `mode' to the silc_server_send_new_channel
2741 as it is required in the Channel Payload now.
2743 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2744 and created a new and real SilChannelPayload to represent the
2745 new generic Channel Payload. Implemented the encode/decode
2746 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2748 * Added silc_server_get_client_channel_list to return the list
2749 of channels the client has joined for WHOIS command reply.
2750 Affected file silcd/server.[ch].
2752 * Implemented the channel list sending in the WHOIS command reply
2753 in server and in the client.
2755 Implemented the channel list displaying on the user interface
2756 as well. Affected file silc/client_ops.c.
2758 * Added silc_channel_payload_parse_list to parse list of Channel
2759 Payloads. It returns SilcDList list of SilcChannelPayloads.
2760 Client for example can use this function to parse the list of
2761 channels it receives in the WHOIS command reply. The caller
2762 must free the list by calling silc_channel_payload_list_free.
2763 Affected files lib/silccore/silcchannel.[ch].
2765 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2767 * Added one new argument <user mode> to the WHOIS command reply
2768 to return the mode of the user in SILC. Updated the protocol
2771 Implemented it to the server and client.
2773 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2775 * Fixed the mode printing on the user interface on joining.
2776 Affected file silc/client_ops.c.
2778 * Implemented the UMODE command and user modes in general to the
2779 client library and to the user interface.
2781 * Implemented the UMODE command to the server.
2783 * The server now sends UNKNOWN_COMMAND error status if client sends
2784 unknown command. Affected file silcd/command.c.
2786 * All server commands now handle the command identifier the right
2787 way when sending the command reply to the client. The client can
2788 use to identify the command replies with the identifier.
2790 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2792 * Added silc_server_get_client_route to resolve the route to
2793 the client indicated by the client ID. Affected file is
2796 * Added silc_server_relay_packet as general function to relay
2797 packet to arbitrary destination. This deprecates functions
2798 like _send_private_message_key, _relay_notify etc. Affected
2799 file is silcd/packet_send.[ch].
2801 Removed silc_server_send_key_agreement,
2802 silc_server_send_private_message_key and
2803 silc_server_packet_relay_notify functions from the file
2804 silcd/packet_send.[ch].
2808 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2809 server. Affected file silcd/packet_receive.[ch].
2811 * Implemented the KILL command to the client. Implemented the
2812 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2813 Affected files lib/silcclient/command[_reply].c and
2814 lib/silcclient/client_notify.c. Implemented the KILL notify
2815 printing in the user inteface.
2817 * Fixed a lot silc_parse_nick memory leaks from the client
2818 library in the file lib/silcclient/command.c.
2820 * Changed the silc_server_send_notify_on_channels's `sender'
2821 argument from SilcSocketConnection to SilcClientEntry to
2822 check the sender as entry and not as connection object and not
2823 to send to the client provided as argument. The affected file
2824 is silcd/packet_send.[ch].
2826 * The notify packets that are destined directly to the client used
2827 to not to be processed by the server. Now changed that and the
2828 server processes all notify packets. After relaying the packet
2829 to the client the notify packet is processed in the server.
2831 * The silc_server_free_client_data now checks whether there is
2832 pending outgoing traffic for the client and purges the data to
2833 the network before removing the client entry.
2835 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2837 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2838 an client is killed from the SILC Network. Updated the protocol
2841 Added new function silc_server_send_notify_killed to the
2842 silcd/packet_send.[ch].
2844 * Added function silc_server_packet_relay_notify to relay notify
2845 packets that are destined directly to a client. In this case
2846 the server does not process the notify packets but merely relays
2847 it to the client. Affected file silcd/packet_send.[ch].
2849 Added also silc_server_packet_process_relay_notify to check
2850 whereto relay the notify. Affected file is
2851 silcd/packet_receive.[ch].
2853 * Implemented the KILL command to the server.
2857 * Added the backup schema desgined last fall to the protocol
2858 specs for everyone to see. The specification is in the
2859 *-spec-xx.txt draft and the packet type definitions for the
2860 backup routers is in *-pp-xx.txt draft. Thusly, added also
2861 new packet type SILC_PACKET_CELL_ROUTERS.
2863 * A big security problem in the implementation discovered. The
2864 signoff of an client did not cause new channel key generation
2865 which it of course should've done. The channel keys must be
2866 always re-generated when client leaves (or signoffs) the channel.
2867 The silc_server_remove_from_channels funtion now handles
2868 the channel key re-generation.
2870 * Added `sender' argument to the silc_server_send_notify_on_channels
2871 to not to send the client provided as argument. Affected file
2872 silcd/packet_send.[ch].
2874 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2876 * Implemented OPER and SILCOPER commands into the server and
2879 * Added silc_auth_verify and silc_auth_verify_data to verify
2880 the authentication directly from the authentication payload.
2881 It supports verifying both passphrase and public key based
2882 authentication. Affected file lib/silccore/silcauth.[ch].
2884 * Added `hash' field to the SilcIDListData structure. It is the
2885 hash negotiated in the SKE protocol. Affected file is
2888 * Slight redesigning of the SilcAuthPayload handling routines.
2889 Do not send SilcPKCS but SilcPublicKey as argument.
2891 * Implemented the public key authentication support to the
2892 serverconfig. The public key is loaded from the provided path
2893 and saved as authentication data to void * pointer. Thus,
2894 changed the unsigned char *auth_data to void *auth_data;
2896 * Fixed SHUTDOWN command to send the reply before the server
2897 is shutdown. :) Affected file silcd/command.c.
2899 * Fixed fatal bug in CONNECT command. The hostname was invalid
2900 memory and server crashed. Affected file silcd/command.c.
2902 * Fixed fatal bug in CLOSE command. The server_entry became
2903 invalid but was referenced later in the command. Affected file
2906 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2908 * Fixed fatal bug in failure packet handling. Server ignored
2909 the failure and thus crashed when it came.
2913 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2915 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2916 that the command may be executed only once in (about) 2 seconds.
2917 The old SILC_CF_LAG flag is same but allows command bursts up
2918 to five before limiting.
2920 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2921 server code. Various commands now includes the CF_LAG_STRICT
2922 flag to disallow any kind of miss-use of the command.
2924 * Fixed the silc_buffer_unformat to not to allocate any data
2925 if the length of the data is zero. It used to allocate the
2926 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2928 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2930 * Changed the format of AdminConnection configuration section
2931 in the server. Added username of the admin to the format.
2932 Affected files silcd/serverconfig.[ch].
2934 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2935 to return admin configuration data by host, username and/or
2938 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2940 * Implemented WHOWAS command to the server. Added the functions:
2942 silc_server_command_whowas_parse,
2943 silc_server_command_whowas_send_reply,
2944 silc_server_command_whowas_from_client and
2945 silc_server_command_whowas_from_server
2947 * Added <Client ID> argument to the WHOWAS command reply. Updated
2948 the protocol specs accordingly.
2950 * Implemented WHOWAS command and command_reply to the client
2953 Implemented the WHOWAS printing on the user interface.
2955 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2957 * Added new argument to the WHOWAS command reply, the real name.
2958 It is an optional argument. Updated the protocol specs.
2960 * Added SilcIDCacheDestructor callback that is registered when
2961 the SilcIDCache is allocated. The callback is called when
2962 an cache entry in the ID Cache expires, or is purged from the
2963 cache. Added into lib/silccore/idcache.[ch].
2965 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2966 to destruct the client entries when the cache entry expires.
2967 Other ID Cache's in server and in the client library ignores
2970 * If the ID Cache entry's `expire' field is zero then the entry
2971 never expires. Added boolean `expire' argument to the
2972 silc_idcache_add function in the lib/silccore/idcache.[ch].
2973 If it is TRUE the default expiry value is used.
2975 * Added silc_server_free_client_data_timeout that is registered
2976 when client disconnects. By default for 5 minutes we preserve
2977 the client entry for history - for WHOWAS command.
2979 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2981 * Added support to the server to enforce that commands are not
2982 executed more than once in 2 seconds. If server receives
2983 commands from client more frequently, timeout is registered
2984 to process the commands. Affected file silcd/command.c.
2985 Added new function silc_server_command_process_timeout.
2987 * Changed NICK_NOTIFY handling in client library to check that
2988 if the client's nickname was changed, so there is no need to
2989 resolve anything from the server.
2991 * Removed error printing from the WHOIS and IDENTIFY commands.
2992 If error occurs then it is ignored silently in the client library.
2993 The application, however, may map the received error to
2994 human readable error string. The application currently maps
2995 the NO_SUCH_NICKNAME error to string.
2997 * Made the command status message public to the application. Moved
2998 them from lib/silcclient/command_reply.c to
2999 lib/silcclient/command_reply.h. The application can map the
3000 received command status to the string with the
3001 silc_client_command_status_message function.
3003 * Added check to the server to check that client's ID is same
3004 as the Source ID in the packet the client sent. They must
3007 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3009 * Added dist-bzip hook to the Makefile.am to make bzip2
3010 compressed distributions.
3012 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3014 * Server now enforces the maximum length for the nickname and
3015 the channel as protocol specification dictates. 128 bytes for
3016 nickname and 256 bytes for channel name.
3018 * Moved the WHOIS printing to the application. The client libary
3019 does not print out the WHOIS information anymore, the application
3020 must do it. Renamed silc_client_command_reply_whois_print to
3021 the silc_client_command_reply_whois_save.
3023 The client's idle time is also sent to the application now, and
3024 the idle is shown on screen.
3026 * Added silc_client_command_reply_identify_save to save the
3027 received IDENTIFY entries.
3029 * Do not check for channel private keys in message sending and
3030 reception if the channel does not have the PRIVKEY mode set.
3031 Affected file lib/silclient/client_channel.c.
3033 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3035 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3036 just surfaced after chaning the JOIN procedure.
3038 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3040 * Added silc_client_get_clients_by_list to get client entries
3041 from Client ID list, that is returned for example by JOIN
3042 and USERS command replies. The application should use this
3043 function for example when JOIN command reply is received to
3044 resolve the clients already on the channel (library does not
3045 do that anymore as USERS command reply is not used in the JOIN
3046 procedure anymore). Affected files lib/silcclient/silcapi.h and
3047 lib/silcclient/idlist.c.
3049 * JOIN command reply and USERS command reply returns now SilcBuffer
3050 pointers instead of unsigned char pointers when returning
3051 the client list and mode list.
3053 * Added <Client ID> argument to the JOIN command reply, mainly
3054 for the server to identify for which client the command was
3055 originally sent. Updated protocol specs accordingly.
3057 * Added SilcDlist private_key pointer to the SilcChannelEntry
3058 in the client to support the channel private keys. Affected
3059 file is lib/silcclient/idlist.h.
3061 * Added SilcChannelPrivateKey argument to the function
3062 silc_client_send_channel_message so that application can choose
3063 to use specific private ke if it wants to. If it is not provided,
3064 the normal channel key is used, unless private keys are set.
3065 In this case the first (key that was added first) is used
3066 as the encryption key.
3068 * Implemented the support for channel private key handling.
3069 Implemented the following functions:
3071 silc_client_add_channel_private_key,
3072 silc_client_del_channel_private_keys,
3073 silc_client_del_channel_private_key,
3074 silc_client_list_channel_private_keys and
3075 silc_client_free_channel_private_keys
3077 Affected file lib/silcclient/client_channel.c.
3079 * Added the support for the private keys in the channel message
3080 sending and encryption and in the message reception and
3081 decryption. Affected funtions are
3082 silc_client_send_channel_message and silc_client_channel_message.
3084 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3086 * Added SKE's key verify callback to the client library's
3087 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3089 * Removed the statement that server (or router) must send USERS
3090 command reply when joining to the channel so that the client
3091 knows who are on the channel. Instead, the client list and
3092 client's mode list is now sent in the JOIN command reply to the
3093 client who joined channel. This is better solution.
3095 * Added function silc_server_get_users_on_channel and function
3096 silc_server_save_users_on_channel to the silcd/server.[ch].
3098 * Removed function silc_server_command_send_users from the
3101 * Do not show topic on the client library anymore. The topic is
3102 sent in the command reply notify to the application and the
3103 application must show the topic now.
3105 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3107 * Added client searching by nickname hash into the IDENTIFY and
3108 WHOIS commands in the server as they were clearly missing from
3109 them. Affected file is silcd/command.c.
3111 * Fixed a bug in private message receiving in the client library.
3112 The remote ID was freed and it wasn't supposed, now it is
3115 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3117 * Minor fix to the channel payload; allocate the data area, as it
3118 needs to be of specific length.
3120 * If the key agreement port is zero then the operating
3121 system will define the bound port. Affected files are
3122 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3124 * Added new function silc_channel_payload_decrypt into the file
3125 lib/silccore/silcchannel.[ch].
3127 * Moved the channel message etc, check from silc_packet_decrypt
3128 to applications. The library calls now a generic
3129 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3130 when the packet is either normal or special. This was done to
3131 allow more wide range of checking that was not allowed when
3132 the code was in library. Now applications can do virtually any
3133 checks to the packet and return to the library the decision how
3134 the packet should be processed. Affected files are
3135 lib/silccore/silcpacket.[ch].
3137 Added silc_server_packet_decrypt_check to the server and
3138 silc_client_packet_decrypt_check to the client library.
3140 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3141 to send with specified source and destination information.
3143 * Channel message delivery between routers was broken after the
3144 channel key distribution was fixed earlier. The channel key
3145 was used be to distributed to other routers as well which is not
3146 allowed by the protocol. Now this is fixed and channel keys
3147 really are cell specific and the channel message delivery between
3148 routers comply with the protocol specification.
3150 * Fixed various commands in server to check also the global list
3151 for the channel entry and not just the local list. The affected
3152 file silcd/command.c.
3154 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3156 * Added assert()s to buffer formatting and unformatting routines
3157 to assert (if --enable-debug) when error occurs. Affected
3158 file: lib/silcutil/silcbuffmt.c.
3160 * Changed to auto-reconnect to check whether the remote host is
3161 router and register the re-connect timeout if it is. It used
3162 to check that whether we are normal server, but router must do
3163 auto-reconnect with another router as well. Affected file
3166 * Removed the [<key len>] option from CMODE command as the cipher
3167 name decides the key length, nowadays. See the defined ciphers
3168 from the protocol specification.
3170 * Added [<hmac>] option to the CMODE command to define the HMAC
3171 for the channel. Added SILC_CMODE_HMAC channel mode.
3173 * Added [<hmac>] option for the JOIN command so that user can
3174 select which HMAC is used to compute the MACs of the channel
3177 * Added Hmac field to the Channel Message Payload. The integrity
3178 of plaintext channel messages are now protected by computing
3179 MAC of the message and attaching the MAC to the payload. The
3180 MAC is encrypted. Now, it is clear that this causes some
3181 overhead to the size of the packet but rationale for this is that
3182 now the receiver can verify whether the channel message decrypted
3183 correctly and also when private keys are set for the channel the
3184 receiver can decrypt the packet with several keys and check from
3185 the MAC which key decrypted the message correctly.
3187 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3188 lib/silccrypt/silccipher.[ch].
3190 * Added silc_hash_len to return the digest length into the
3191 lib/silcrypt/silchash.[ch].
3193 * Rewrote parts of Silc Channel Payload interface in the
3194 lib/silccore/silcchannel.[ch]. The encode function now also
3195 encrypts the packet and parse function decrypts it.
3197 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3199 * Fixed a minor formatting bug in the SKE's key material processing.
3200 It actually might have processed the keys wrong way resulting
3203 * Redefined the mandatory HMAC algorithms and added new algorithms.
3204 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3205 and hmac-md5 truncated to 96 bits. The mandatory is now
3206 hmac-sha1-96. Rest are optional (including the one that used
3207 to be mandatory). Rationale for this is that the truncated HMAC
3208 length is sufficient from security point of view and can actually
3209 make the attack against the HMAC harder. Also, the truncated
3210 HMAC causes less overhead to the packets. See the RFC2104 for
3213 * Added new [hmac] configuration section. The SKE used to use
3214 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3215 is of course wrong. The official names that must be proposed in
3216 the SKE are the ones defined in the protocol specification
3217 (hmac-sha1-96 for example). The user can configure any hmac
3218 using any hash function configured in the [hash] section. At
3219 least, the mandatory must be configured.
3221 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3223 * Added HMAC list to the SKE proposal list. It has now both
3224 hash algorithm list and HMAC list. This makes the protocol
3225 incompatible with previous versions. The SKE now seems to work
3226 the way it is supposed to work, for the first time actually.
3228 * Defined plain Hash algorithms to the protocol specification.
3231 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3233 * Implemented support for key agreement packets into the server.
3234 Added functions silc_server_key_agreement and
3235 silc_server_send_key_agreement. Other than these functions,
3236 server has nothing to do with this packet.
3238 * Added support for private message key packets into the server.
3239 Added functions silc_server_private_message_key and
3240 silc_server_send_private_message_key.
3244 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3245 called in the protocol's final callback instead in the END
3246 protocol state. This makes a little more sense and in the same
3247 time in client we can use the same protocol routines for normal
3248 key exchange and to key agreement packet handling as well.
3250 * Added to both client's and server's KE protocol context the
3251 SilcSKEKeyMaterial pointer to save the key material. We will
3252 bring the key material to the protocol's final callback by doing
3253 this. The final callback must free the key material.
3255 * Added SKE's packet_send callback into client's KE protocol
3256 context so that the caller can choose what packet sending function
3257 is used. This way we can use different packet sending when
3258 doing normal SKE when doing key agreement packet handling (in
3259 the key agreement packet handling we do not want to encrypt
3262 * Implemented the responder side of the key agreement routines
3263 in the client. The client can now bind to specified port and
3264 accept incoming key negotiation. The key material is passed
3265 to the application after the protocol is over.
3267 * Implemented the processing of incoming Key Agreement packet
3268 in the client. Added function silc_client_key_agreement to
3271 * Implemented the intiator side of the key agreement routines
3272 in the client. The client can now initiate key agreement with
3273 another remote client. The key material is passed to the
3274 application after the protocol is over.
3276 * Created client_keyagr.c to include all the key agreement
3279 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3280 SILC_TASK_CALLBACK except that it is not static.
3282 * Created client_notify.c and moved the Notify packet handling
3283 from the client.[ch] into that file.
3285 * Created client_prvmsg.c and moved all private message and
3286 private message key routines from the client.[ch] into that file.
3288 * Create client_channel.c and moved all channel message and
3289 channel private key routines from the client.[ch] into that file.
3291 * Changed silc_client_get_client_by_id_resolve to resolve with
3292 WHOIS command instead of IDENTIFY command, in the file
3293 lib/silclient/idlist.c.
3295 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3297 * Implemented the SKE's responder side to the Client library.
3299 * When FAILURE is received to the protocol do not trust it
3300 blindly. Register a timeout to wait whether the remote closes
3301 the connection as it should do it, only after that process the
3302 actual failure. This was changed to both client and server.
3304 * Added client_internal.h to include some of the structures
3305 there instead of client.h in lib/silcclient/.
3307 * Added function silc_task_unregister_by_callback to unregister
3308 timeouts by the callback function.
3310 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3312 * Some "Incomplete WHOIS info" errors has been appearing on the
3313 log files. Took away the entry->userinfo check from WHOIS
3314 reply sending. The entry->userinfo is now " " if client did not
3315 provide one. I thought this was fixed earlier but something
3316 is wrong still. Let's see if the error still appears.
3318 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Fixed a minor bug in the login when the channel key is
3321 re-generated in the server. It used to generate the key in
3322 wrong order and thus caused problems in the channel traffic.
3324 * Fixed a minor bug in channel key distsribution after
3325 KICK command. The key was not sent to the router even though
3328 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Added silc_ske_process_key_material_data as generic routine
3331 to process any key material as the SILC protocol dictates. The
3332 function is used by the actual SKE library but can be used by
3333 applications as well. This relates to the private message keys
3334 and the channel private keys since they must be processed the
3335 same way the normal SILC session keys. The protocol dictates
3336 this. Affected files: lib/silcske/silcske.[ch].
3338 Added also silc_ske_free_key_material to free the
3339 SilcSKEKeyMaterial structure.
3341 * Defined silc_cipher_set_key function to set the key for
3342 cipher without using the object's method function. The affected
3343 files: lib/silccrypt/silccipher.[ch].
3345 * Implemented silc silc_client_add_private_message_key,
3346 silc_client_add_private_message_key_ske,
3347 silc_client_del_private_message_key,
3348 silc_client_list_private_message_keys and
3349 silc_client_free_private_message_keys functions in the
3352 Added functions silc_client_send_private_message_key to send
3353 the Private Message Key payload and silc_client_private_message_key
3354 to handle incoming Private Message Key payload.
3356 * Added Cipher field to the Private Message Key payload to set
3357 the cipher to be used. If ignored, the default cipher defined
3358 in the SILC protocol (aes-256-cbc) is used.
3360 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Removed lib/silcclient/ops.h file.
3364 Redefined parts of the SILC Client Library API. Created new
3365 file silcapi.h that deprecates the ops.h file and defines the
3366 published Client Library API. Defined also private message key
3367 API and channel private key API into the file.
3369 This is the file that the application must include from the
3370 SILC Client Library. Other files need not be included by
3371 the application anymore.
3373 * Added new key_agreement client operation callback and also
3374 defined the Key Agreement library API for the application.
3376 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3378 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3379 is used by clients to request key negotiation between another
3380 client in the SILC network. If the negotiation is started it
3381 is performed using the SKE protocol. The result of the
3382 negotiation, the secret key material, can be used for example
3383 as private message key.
3385 Implemented the Key Agreement payload into the files
3386 lib/silccore/silauth.[ch].
3388 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3390 * Redefined ciphers for the SILC protocol. Added some new ciphers
3391 and defined the key lengths for the algorithms. Changed the
3392 code accordingly. The default key length is now 256 bits.
3394 * Fixed SKE key distribution function silc_ske_process_key_material
3395 when the key length is more than 128 bits. The default key
3396 length in SILC is now 256 bits.
3398 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3399 to indicate unsupported algorithm.
3401 * Renamed rijndael.c to aes.c and all functions as well.
3403 * Fixed a long standing channel key setting bug in client library.
3404 Weird that it has never surfaced before.
3406 * Fixed bug in channel deletion. If the entire channel is removed
3407 then it must also delete the references of the channel entry
3408 from the client's channel list as the client's channel entry and
3409 the channel's client entry share same memory.
3411 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3413 * Implemented CONNECT and SHUTDOWN commands in the client.
3415 * Implemented CLOSE command to the client.
3417 * Added the function silc_idlist_find_server_by_name into the
3418 files silcd/idlist.[ch].
3420 Added the function silc_idlist_find_server_by_conn into the
3421 files silcd/idlist.[ch].
3423 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3425 * DIE command was renamed to SHUTDOWN. Updated the both code
3428 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3429 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3431 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3434 * Added function silc_server_create_connection function to create
3435 connection to remote router. My server implementation actually
3436 does not allow router to connect to normal server (it expects
3437 that normal server always initiates the connection to the router)
3438 so the CONNECT command is only good for connecting to another
3441 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3443 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3444 or some other client was kicked from the channel.
3446 Implemented the handling of the notify type to both client
3449 Implemented silc_server_send_notify_kicked to send the KICKED
3450 notify. It is used to send it to the server's primary router.
3452 * Implemented the KICK command into server and client.
3454 * Added `query' argument to the silc_idlist_get_client function
3455 to indicate whether to query the client from server or not if
3458 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3459 to indicate that the client is not channel founder.
3463 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3465 * Removed the rng context from SilcPacketContext structure and
3466 changed that the packet routine uses the Global RNG API.
3468 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3470 * Added support for quit message that client can "leave" on the
3471 channel when it quits the SILC. It is ditributed inside the
3472 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3474 Added silc_server_free_client_data that will take the
3475 signoff message as argument.
3477 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3479 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3481 * Updated parts of the protocol specification to keep it up
3484 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3486 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3487 payloads in one packet.
3489 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3490 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3491 use now the new List flag.
3493 * Also deprecated the following packet types: REPLACE_ID,
3494 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3496 * Added list support for Notify packet in server.
3498 * Added silc_server_send_notify_channel_change to send the
3499 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3500 the silc_server_send_replace_id.
3502 * Added silc_server_send_notify_nick_change to send the
3503 NICK_CHANGE notify type. Deprecates the function
3504 silc_server_send_replace_id.
3506 * Added silc_server_send_notify_join to send the JOIN notify type.
3507 Deprecates the function silc_server_send_new_channel_user.
3509 * Added silc_server_send_notify_leave to send LEAVE notify type.
3510 Deprecates the function silc_server_send_remove_channel_user.
3512 * Added silc_server_send_notify_cmode and
3513 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3514 types. Deprecates the silc_server_send_set_mode function.
3516 * Added SERVER_SIGNOFF notify type to indicate that server has
3517 quit. This means that all clients on the channel from that
3518 server will drop. This can be also used when netsplit happens.
3520 Deprecated REMOVE_ID packet type since it is not needed anymore
3523 Added silc_server_send_notify_server_signoff to send the
3524 SERVER_SIGNOFF notify type. Deprecates the function
3525 silc_server_send_remove_id.
3527 Added also silc_server_send_notify_signoff to send the
3528 SIGNOFF notify type.
3530 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3531 SILC protocol from this day on. Changed the protocol
3532 specification as well.
3534 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3535 notify type. It is used between routers to notify about
3536 topic changes on a channel.
3538 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3541 * Partly updated the protocol specification to comply with the
3542 changes now made. It is still though a bit outdated.
3544 * The JOIN notify type now takes one extra argument <Channel ID>.
3545 The packet used to be destined to the channel but now the
3546 JOIN type may be sent as list thus it is impossible to
3547 destine it to any specific channel. By adding this argument
3548 it is again possible.
3550 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3552 * Added CREDITS file. The CHANGES and CREDITS file will appear
3553 in the distribution as well.
3555 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3557 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3558 types in the server's silcd/packet_receive.c.
3560 * Implemented CMODE and CUMODE to work in router environment.
3562 * Fixed minor encoding and decoding buglet from the
3563 lib/silccore/silcmode.c.
3565 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3568 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3570 * Changed all SilcConfigServer* and silc_config_server* to
3571 SilcServerConfig* and silc_server_config*, respectively.
3574 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3576 * Associated the ID (client or server ID) to the Authentication
3577 Payload to avoid any possibility of forging. Updated the
3578 protocol specification and the code accordingly.
3580 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3582 * The RSA key length is now save to the RsaKey context in the
3583 key generation process in lib/silccrypt/rsa.c. The key length
3584 is now used to figure out the maximum size of the block allowed
3585 to be encrypted/signed.
3587 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3588 is equivalent to the silc_mp_mp2bin but does not allocate any
3591 * Changed silc_mp_mp2bin API to take length argument. If it is
3592 non-zero then the buffer is allocated that large. If zero, then
3593 the size is approximated using silc_mp_sizeinbase, which however
3596 * Created Global RNG API which is global RNG that application can
3597 initialize. After initializing, any routine anywhere in the
3598 code (including library) can use RNG without allocating a new
3599 RNG object. This was done to allow this sort of use of the
3600 RNG in code that has no chance to allocate RNG object. All
3601 applications currently allocate this and many routines in the
3602 library use this. Affected file lib/silccrypt/silcrng.[ch].
3604 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3605 it to use the Global RNG API.
3607 * Defined Authentication Payload into protocol specification that
3608 is used during SILC session to authenticate entities. It is
3609 used for example by client to authenticate itself to the server
3610 to obtain server operator privileges.
3612 Implemented this payload into the lib/silccore/silcauth.[ch].
3613 Implemented also routines for public key based authentication
3614 as the new protocol specification dictates.
3616 Moved definitions of different authentication methods from
3617 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3619 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3620 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3621 silc_pkcs_verify_with_hash functions into the file
3622 lib/silccrypt/silcpkcs.[ch].
3624 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3626 * The client entry's userinfo pointer must be always valid.
3627 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3628 will fail since it requires the userinfo. Now, the userinfo
3629 is allocated as "" if actual userinfo does not exist. Actually,
3630 it must exist and it is totally Ok to drop client connections
3631 that does not announce the userinfo. However, we will make
3632 this workaround for now.
3634 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3635 to return the remote port by socket.
3637 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3639 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3640 SILC_SERVER_PENDING_EXEC and added an new macro
3641 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3642 data or when error occurs while processing the pending command.
3644 Added new argument `destructor' into silc_server_command_pending
3645 and to the SilcServerCommandPending object. This destructor is
3646 now called after calling the pending callback or if error occurs
3647 immediately. If error occurs the actual pending callback won't
3648 be called at all - only the destructor. The destructor may be
3649 NULL if destructor is not needed.
3651 All this applies for client library code as well. Similar
3652 changes were made there as well for the pending commands.
3654 In the client, the application must now allocate the
3655 SilcClientCommandContext with the silc_client_command_alloc
3658 * Added reference counter to the SilcServerCommandContext. Added
3659 function silc_server_command_alloc and silc_server_command_dup
3662 Same type of functions added to the client library for the same
3665 * Removed the cmd_ident from IDListData away since it is now
3666 global for all connections. It is the command identifier used
3667 in command sending and with pending commands. The affected file
3670 * Added reference counter to the SilcSocketConnection objecet to
3671 indicate the usage count of the object. The object won't be
3672 freed untill the reference counter hits zero. Currently only
3673 server uses this, and client ignores it. The client must be
3674 set to use this too later. The affected files are
3675 lib/silccore/silcsockconn.[ch]. Added also the function
3676 silc_socket_dup to increase the reference counter.
3678 This was mainly added because it is possible that the socket
3679 is removed underneath of pending command or other async
3680 operation. Now it won't be free'd and proper DISCONNECTING
3681 flags, etc. can be set to avoid sending data to connection that
3682 is not valid anymore.
3684 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3685 the connection. After that it sets SILC_SET_DISCONNECTED.
3686 It is, however, possible that the socket data is not still freed.
3687 The silc_server_packet_process now checks that data is not
3688 read or written to connection that is DISCONNECTED. The socket
3689 get's freed when the reference counter hits zero.
3691 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3693 * Changed the client operation API: channel_message operation's
3694 `sender' is now the client entry of the sender, not the nickname
3695 and the `channel' is the channel entry, not the channel name.
3697 In the private_message operation the `sender' is now also the
3698 client entry of the sender not the nickname.
3700 Affected file is lib/silcclient/ops.h and all applications
3701 using the client operations.
3703 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3705 * Moved the calling of ops->connect() from connect_to_server_final
3706 into receive_new_id functin since that is the point when the
3707 client is actually allowed to send traffic to network. The
3708 affected file is lib/silcclient/client.c.
3710 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3712 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3713 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3714 (if needs broadcasting) instead of broadcasting the packets one
3715 by one which would make a burst in the network traffic.
3717 * Added `broadcast' argument to the functions in silcd/server.[ch]
3718 silc_server_create_new_channel[_with_id] to indicate whether
3719 to send New Channel packet to primary router.
3721 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3723 * Added new function into the silcd/server.[ch] files:
3724 silc_server_create_new_channel_with_id to create new channel with
3725 already existing Channel ID.
3727 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3728 lib/silccore/silcpacket.h. This packet is used t send list of
3729 Set Mode payloads inside one packet. Server uses this to set
3730 the modes for the channels and clients on those channels, that it
3731 announced to the router when it connected to it. The protocol
3732 specification has been updated accordingly.
3734 * The silc_server_new_channel did not handle the packet coming
3735 from normal server as it normally does not send that. However,
3736 when it announces its channels it does send it. Implemented
3737 the support for that.
3739 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3740 into the file lib/silccore/id.h.
3742 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Fixed memory leaks in the functions silc_idlist_del_client,
3745 silc_idlist_del_channel and silc_idlist_del_server in the file
3746 silcd/idlist.c. All of those leaked like a sieve.
3748 * Fixed some small memory leaks in the client's function
3749 silc_client_notify_by_server.
3751 * Added functions into silcd/server.c: silc_server_announce_clients,
3752 silc_server_announce_channels and silc_server_announce_server.
3753 These functions are used by normal and router server to announce
3754 to its primary router about clients, channels and servers (when
3755 router) that we own. This is done after we've connected to the
3758 These functions effectively implements the following packet types:
3759 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3760 and SILC_PACKET_NEW_ID_LIST.
3762 * Added new functions into the silcd/packet_receive.[ch]:
3763 silc_server_new_id_list, silc_server_new_channel_list and
3764 silc_server_new_channel_user_list to handle the incoming
3765 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3767 * Added support of changing Channel ID in the function
3768 silc_server_replace_id. If the server that announces a channel
3769 to the router already exists in the router (with same name but
3770 with different Channel ID), router is responsible to send
3771 Replace ID packet to the server and force the server to change
3772 the Channel ID to the one router has.
3774 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3775 client that the Channel ID has been changed by the router. The
3776 normal server sends this to the client. Client must start using
3777 the new Channel ID as the channel's ID.
3779 Implemented handling of this new type into lib/silcclient/client.c
3780 into the function silc_client_notify_by_server.
3782 * Added new function silc_idlist_replace_channel_id into the files
3783 silcd/idlist.[ch] to replace the Channel ID.
3785 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3787 * Call silc_server_command_identify_check always when processing
3788 the IDENTIFY command in silcd/command.c
3790 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3792 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3793 send keepalive packets. The packet can be sent by clients,
3794 servers and routers.
3796 Added function silc_socket_set_heartbeat into the file
3797 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3798 If not set, the heartbeat is not performed. The actual
3799 heartbeat is implemented in the low level socket connection
3800 library. However, application is responsible of actually
3803 Added silc_server_send_heartbeat to send the actual heartbeat
3804 packet into silcd/packet_send.[ch]. Server now performs
3805 keepalive with all connections.
3807 * Added silc_task_get_first function into lib/silcutil/silctask.c
3808 to return the timeout task with shortest timeout. There was a bug
3809 in task unregistration that caused problems. TODO has been
3810 updated to include that task system must be rewritten.
3812 * The client library will now resolve the client information when
3813 receiving JOIN notify from server for client that we know but
3814 have incomplete information.
3816 * Rewrote parts of silc_server_remove_from_channels and
3817 silc_server_remove_from_one_channel as they did not remove the
3818 channel in some circumstances even though they should've.
3820 * Encryption problem encountered in server:
3822 The LEAVE command used to send the Channel Key packet to the
3823 router immediately after generating it. However, the code
3824 had earlier sent Remove Channel user packet but not immediately,
3825 ie. it was put to queue. The order of packets in the router
3826 was that Channel Key packet was first and Remove Channel User
3827 packet was second, even though they were encrypted in the
3828 reverse order. For this reason, MAC check failed. Now, this
3829 is fixed by not sending the Channel Key packet immediately but
3830 putting it to queue. However, this is more fundamental problem:
3831 packets that are in queue should actually not be encrypted
3832 because packets that are sent immediately gets encrypted
3833 actually with wrong IV (and thus MAC check fails). So, packets
3834 that are in queue should be encrypted when they are sent to
3835 the wire and not when they put to the queue.
3837 However, the problem is that the current system has not been
3838 designed to work that way. Instead, the packet is encrypted
3839 as soon as possible and left to the queue. The queue is then
3840 just purged into wire. There won't be any fixes for this
3841 any time soon. So, the current semantic for packet sending
3844 o If you send packet to remote host and do not force the send
3845 (the packet will be in queue) then all subsequent packets to the
3846 same remote host must also be put to the queue. Only after the
3847 queue has been purged is it safe again to force the packet
3850 o If you send all packets immediately then it safe to send
3851 any of subsequent packets through the queue, however, after
3852 the first packet is put to queue then any subsequent packets
3853 must also be put to the queue.
3855 Follow these rules and everything works fine.
3857 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3859 * Added new function silc_server_remove_clients_by_server to
3860 remove all client entries from ID list when the server connection
3861 is lost. In this case it is also important to invalidate all
3862 client entires as they hold the invalid server entry. This
3863 fixes fatal bug when server has lost connection and will reconnect
3866 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3868 * Made some sanity checks to silc_server_daemonise like to check
3869 whether the requested user and group actually exists.
3871 * Added sanity check to SKE's silc_ske_responder_finish to check
3872 that the public and private key actually is valid.
3874 * Invalidate the client's nickname when receiving Replace ID
3875 packet and the Client ID is being replaced. This means that the
3876 server will query the nickname if someone needs it (client)
3879 * Sort the ID Cache in client library when the ID Cache data
3880 has changed (needs sorting).
3882 * Do not allow for SILC client to create several connections to
3883 several servers. The client does not support windows right now
3884 and generating multiple connections causes weird behaviour.
3886 Irssi-silc client does support windows and can handle several
3887 connections without problems, see: www.irssi.org and SILC plugin.
3889 * Fixed some places where client was added to the IDList. The
3890 rule of thumb is following (in order to get everything right):
3891 If the client is directly connected local client then the
3892 `connection' argument must be set and `router' argument must be
3893 NULL to silc_idlist_add_client function. If the client is not
3894 directly connected client then the `router' argument must
3895 bet set and the `connection' argument must be NULL to the
3896 silc_idlist_add_client function.
3898 * The funtion silc_server_packet_send_local_channel actually did
3899 not check whether the client was locally connected or not. It
3900 does that now. Fixed a bug related to LEAVE command.
3902 * Fixed Remove Channel User payload parsing bug in server's
3903 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3905 * The server's silc_server_save_channel_key now checks also the
3906 global ID list for the channel as it might not be in the local
3907 list. Fixed a bug related to LEAVE command.
3909 * Is this the end of the [<unknown>] buglet that has been lurking
3910 around for a long time? A little for loop fix in server's
3911 silc_server_command_whois_parse that is used by both IDENTIFY
3912 and WHOIS command. At least, this was a clear bug and a cause
3913 of one type of [<unknown>] buglet.
3915 * WHOIS and IDENTIFY commands call the function
3916 silc_server_command_[whois/identify]_check function even if
3917 we are not router server.
3919 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3921 * Added --with-gmp configuration option. If set the GMP
3922 is always compiled in the SILC source tree. If not set then
3923 it is checked whether the system has the GMP3 installed. If
3924 it has then the GMP won't be compiled (the system's headers
3925 and library is used), if it doesn't have it then the GMP is
3926 compiled in the SILC source tree.
3928 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3930 * Changed RSA private exponent generation to what PKCS #1
3931 suggests. We try to find the smallest possible d by doing
3932 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3933 not security fix but optimization.
3935 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3937 * Added new config entry [Identity] to fork the server and run
3938 it as specific user and group. A patch from Bostik.
3940 * Imported Dotconf configuration library into lib/dotconf.
3941 This will be used to create the SILC configuration files later.
3942 It will appear in the distsribution after this commit.
3944 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3946 * A big code auditing weekend happening. Auditing code for
3947 obvious mistakes, bugs and errors. Also, removing any code
3950 Removed files for being obsolete:
3952 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3953 inline in the file lib/silcutil/silcbuffer.h)
3955 o lib/silcutil/silcbufutil.c (the header has inline versions)
3957 Changed code to fix possible error conditions:
3959 o The buffer formatting routines now check that the destination
3960 buffer really has enough space to add the data. This applies for
3961 both buffer formatting and unformatting
3962 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3963 unformatting was changed to accomodate following rules:
3964 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3965 sent to the function while XXX_*STRING will not allocate or copy
3966 the data into the buffer. Instead it sets the pointer from the
3967 buffer into the pointer sent as argument (XXX_*STRING used to
3968 require that the pointer must be allocated already). This change
3969 makes this whole thing a bit more consistent and more optimized
3970 (note that the data returned in the unformatting with XXX_*STRING
3971 must not be freed now). The routines return now -1 on error.
3973 o Tried to find all code that use buffer_format and buffer_unformat
3974 and added return value checking to prevent formatting and
3975 especially unformatting errors and possible subsequent fatal
3978 o Changed ske->x and ske->KEY to mallocated pointers in
3979 lib/silcske/silcske.h. Fixed possible data and memory leak.
3981 o Added return value checking to all *_parse* functions. Fixed
3982 many memory leaks as well.
3984 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3985 so that buffer overflows would not happen. All code now also
3986 checks the return value as it can fail.
3988 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3990 * Added reconnection support to server if the normal server looses
3991 its connection to the router (for example if router is rebooted).
3992 The server performs normal reconnection strategy implemented
3993 to the server. Affected file silcd/server.c.
3995 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3997 * Added new packet type SILC_PACKET_SET_MODE that is used to
3998 distribute the information about changed modes (for clients,
3999 channels and clients channel modes) to all routers in the
4000 network. Updated the protocol specification accordingly.
4002 Added functions into silcd/packet_send.c and
4003 silcd/packet_receive.c: silc_server_send_set_mode,
4004 silc_server_set_mode.
4006 Added new files silcmode.[ch] into lib/silccore that implements
4007 the encoding and decoding of Set Mode Payload. Added new type
4008 SilcSetModePayload. Moved the definitions of different modes
4009 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
4011 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4013 * Oops, a little mistake in server's connection authentication
4014 protocol. The protocol is not ended with FAILURE but with
4015 SUCCESS if the authentication is Ok. :) Affected file is
4018 * Implemented NICK_CHANGE notify handling in server in the file
4019 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
4020 the local clients on the channel. After the changing nickname
4021 in router environment snhould work and the [<unknown>] nickname
4022 should appear no more.
4024 The silc_server_replace_id function that receives the Replace ID
4025 payload now sends the NICK_CHANGE notify type also in the file
4026 silcd/packet_receive.c
4028 * Changed WHOIS and IDENTIFY command to support the maximum amount
4029 of arguments defined in protocol specs (3328 arguments). This
4030 fixed a bug that caused problems when there were more than three
4033 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4035 * Added extra parameter, command identifier, to the
4036 silc_client_send_command so that explicit command identifier
4039 Changed that ID list routines uses specific command identifier
4040 when sending WHOIS/IDENTIFY requests to the server so that they
4041 can be identified when the reply comes back.
4043 Affected files lib/silcclient/command.[ch],
4044 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4046 * Added `sender' argument to silc_server_packet_send_to_channel
4047 to indicaet the sender who originally sent the packet to us
4048 that we are now re-sending. Ignored if NULL. Affected file
4049 silcd/packet_send.[ch].
4051 * Added some server statistics support in silcd/server_internal.h
4052 SilcServerStatistics structure and around the server code. Also
4053 send some nice statistics information when client is connecting
4056 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4058 * Fixed channel ID decoding in server's JOIN command reply in
4059 silcd/command_reply.c
4061 * Fixed braodcasting of replace ID payload to not to send it if
4062 we are standalone server in silcd/packet_receive.c.
4064 * Fixed all channel message sending routines to not to send
4065 packets to clients that has router set, since they are routed
4066 separately in the same function earlier. Affects file
4067 silcd/packet_send.c and all channel packet sending functions.
4069 * In USERS reply, res_argv[i] are not allocated, the table
4070 is allocated. Thus changed that free the table, not its
4073 * In server's whois_check and identify_check if the client is
4074 locally connected do not send any WHOIS commands - they are not
4077 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Fixed some minor bugs in client when sending WHOIS command. The
4080 arguments was in wrong order.
4082 * Removed statis function add_to_channel from server in
4083 silcd/command.c that was previously used with the joining but
4086 * Tested USERS command in router environment successfully with two
4087 routers, two servers and two clients.
4089 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4091 * Reorganized the USERS command and command reply in client library
4092 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4093 When the command is given by user we register a pending command
4094 callback that will reprocess the command after the reply has been
4095 received from the server. When reprocessing the packet we then
4096 display the information. Thus, the USERS information is displayed
4097 now in the command callback instead of in the command reply
4098 callback. The processing of the command is same as previously
4099 when server has sent the command reply in the JOINing process.
4101 * Added to USERS command in silcd/command_reply.c to join the client,
4102 we didn't use to know about, to the channel after we've created
4103 a client entry for it. Also, for clienet we did know already still
4104 check whether it is on the channel or not and add it if not.
4106 * Removed silc_server_command_join_notify as the function and its
4109 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4111 * Changed the client's pending command handling to the same as the
4112 server's pending command handling. It is also now possible to
4113 execute command reply functions from other command reply
4114 function as the function callbacks for commands and command
4115 replies are one and same. The pending commands are not static
4116 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4117 in client connection context. Thus, pending commands are server
4118 connection specific as it is convenient.
4120 Changed the function silc_client_command_pending and
4121 silc_client_command_pending_del and added new function
4122 silc_client_command_pending_check. Removed the
4123 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4126 * Added cmd_ident, current command identifier, to the client
4127 connection context in lib/silcclient/client.h to keep track on
4128 command identifiers used in command sending. Client's command reply
4129 function handling now supports the mandatory command identifiers.
4131 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4132 funtions in client to fully support pending command callbacks.
4134 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4135 as one of the arguments to the application in the command reply
4138 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4139 before first releasing SILC but came back. Now it is removed again
4140 and should come back nomore. The FORWARDED flag was used only
4141 by the JOINing procedure by forwarding the command packet to router.
4142 Now, the JOINing procedure has been changed to more generic (due
4143 to various router environment issues) and FORWARDED is not needed
4144 anymore for anything. The protocol specification is yet to be
4147 Now, removed silc_server_packet_forward from server and the flag
4148 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4150 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4152 * Renamed NAMES command to USERS command. The NAMES was named that
4153 due to historical reasons. Now it is renamed. Also, rewrote
4154 parts of the USERS command. The nickname list is not sent anymore
4155 by the server. Only Client ID and mode lists are sent in the USERS
4156 command. Changed this also to the protocol specification.
4158 The client now resolves the names and stuff after it receives
4159 the USERS list from the server when joining to the channel.
4161 * WHOIS and IDENTIFY commands has been changed to support multiple
4162 Client ID's per command. One can now search for multiple users
4163 in the network by sending only one WHOIS or IDENTIFY command.
4164 Changed the code and the protocol specifications.
4166 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4167 uses silc_server_command_whois_parse to parse the request. */
4169 * If normal server, do not parse the WHOIS and IDENTIFY requests
4170 before sending it to the router. Saves some time.
4172 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4174 * Fixed JOIN command on client library. Wrong number of arguments
4175 used to crash the client.
4177 * Added silc_server_channel_has_global function to check whether
4178 channel has global users or not.
4180 * Added silc_server_channel_has_local function to check whether channel
4181 has locally connected clients on the channel.
4183 * The silc_server_remove_from_one_channel now checks whether the
4184 channel has global users or not after given client was removed from
4185 the channel. It also checks whether the channel has local clients
4186 on the channel anymore. If it does not have then the channel entry
4187 is removed as it is not needed anymore.
4189 * The silc_server_notify now checks on JOIN notify whether the joining
4190 client is one of locally connected or global. If it is global then
4191 the channel has now global users on the channel and that is marked
4192 to the channel entry. Also, it now saves the global client to
4193 global list who is joining and JOINs it to the channel. This is
4194 for normal server, that is.
4196 Changed silc_server_send_notify_on_channel,
4197 silc_server_packet_relay_to_channel and
4198 silc_server_packet_send_to_channel check if we are normal server
4199 and client has router set (ie. global client) do not send the
4200 message to that client, as it is already routed to our router.
4202 * Implemented LEAVE notify type handling in silc_server_notify
4205 * Tested LEAVE command in router environment successfully. Tested
4206 with two routers, two servers and two clients.
4210 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4212 * Implemented SIGNOFF notify type handling in silc_server_notify
4215 * silc_server_remove_id now removes the client entry from all channels
4216 it has joined and thusly sends SIGNOFF notify type.
4218 * Rewrote the NAMES list generation in server by removing two excess
4219 loops. The lists are created now inside one loop.
4221 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4223 * silc_server_remove_channel_user checks now also global list
4224 for channel and client.
4226 * silc_server_new_channel_user checks now both local and global
4227 list for channel and client. Fixed a bug in client id decoding.
4228 Used to decode wrong buffer.
4230 * silc_server_channel_message checks now both local and global
4231 list for channel entry.
4233 * Tested channel joining (hence JOIN) in router environment
4234 successfully. Tested with two routers, two servers and two
4237 * Tested channel message sending in router environment successfully.
4239 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4241 * Added silc_server_save_channel_key into server.[ch] to save the
4242 received channel key in Channel Key payload processing. It is
4243 also used in JOIN command reply handling.
4245 Equivalent function silc_client_save_channel_key added into
4246 client.[ch] into client library.
4248 * Changed JOIN command reply to send information whether the channel
4249 was created or not (is existing already) and the channel key
4250 payload. Changed protocol specs accordingly.
4252 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4253 the request was sent by ID and not by nickname. Crashed on
4256 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4258 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4259 now correctly save the received data.
4261 * silc_server_free_sock_user_data now notifies routers in the
4262 network about entities leaving the network.
4264 At the same time implemented functions silc_server_remove_id
4265 and silc_server_send_remove_id to receive and send REMOVE_ID
4266 packets. The packet is used to notify routers in the network
4267 about leaving entities. The ID removed will become invalid in
4270 * Added function silc_idlist_del_server into server. Removes and
4271 free's server entry from ID list.
4273 * silc_server_private_message function now checks, if we are router,
4274 that the destination ID really is valid ID, naturally.
4276 * In router when NEW_ID packet is received (for new client) the
4277 hash of the Client ID is saved in the ID Cache but the
4278 client->nickname is set to NULL, instead of putting the hash
4281 IDENTIFY command now also checks that client->nickname must be
4282 valid. If it is not if will request the data from the server who
4283 owns the client. Added new function
4284 silc_server_command_identify_check.
4286 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4287 to set the command to already allocated Command Payload.
4289 * Tested private message sending in router environment with two
4290 routers, two servers and two clients. Fixed minor bugs and now
4293 * Fixed segfault from client's NAMES command. Used to crash if
4296 * Forwarded packets must not be routed even if it is not destined
4297 to the receiver. Changed server code comply with this.
4299 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4301 * Added `require_reverse_mapping' boolean value to ServerParams
4302 structure. If TRUE (not default) the server will require that
4303 the connecting host has fully qualified domain name.
4305 If the reverse mapping is not required and hostname could not be
4306 found the IP address is used as hostname.
4308 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4310 * Implemented version string checking to both client and server.
4311 The check is incomplete currently due to the abnormal version
4312 strings used in development version of SILC.
4314 * Changed all command functions in server to use the new
4317 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Changed char *data to unsigned char *data in ID Cache system to
4320 support binary data as ID Cache data. Changed code to support
4321 binary data in lib/silccore/idcache.c.
4323 * Renamed silc_server_packet_relay_command_reply to
4324 silc_server_command_reply as it is normal packet receiving
4325 function. Rewrote the function to accept command replys for
4326 servers and not only for clients.
4328 * Mark remote router always as registered server if we are connecting
4329 to it. Otherwise, commands sent by the router to us are ignored.
4331 * All ID List find routines now returns the ID Cache Entry pointer
4332 as well if requested.
4334 * WHOIS command works now in router environment, tested with two
4335 routers, two servers and two clients.
4337 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4338 in router environment (as it is almost equivalent to WHOIS) but
4339 hasn't been tested thoroughly. Added new functions:
4341 silc_server_command_identify_parse
4342 silc_server_command_identify_send_reply
4343 silc_server_command_identify_from_client
4344 silc_server_command_identify_from_server
4346 * Disabled route cache adding because adding two different ID's with
4347 same IP replaces the old cache entry thus giving wrong route.
4348 The entry->router->connection is always the fastest route anyway
4349 so route cache may not be needed. Of course, new routes maybe
4350 established after receiving the ID when the entry->router->connection
4351 might not be anymore the most optimal.
4353 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4355 * Add route cache for received ID for fast routing.
4357 * Added silc_server_packet_route to route received packet on router
4358 that is not destined to us.
4360 * Renamed silc_server_get_route to silc_server_route_get.
4362 * Added id_string and id_string_len fields into SilcServer to
4363 include encoded ServerID for fast comparing without excess
4364 encoding of the ID's.
4366 * Cleaned up WHOIS command on server side. Added following static
4369 silc_server_command_whois_parse
4370 silc_server_command_whois_check
4371 silc_server_command_whois_send_reply
4372 silc_server_command_whois_from_client
4373 silc_server_command_whois_from_server
4375 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4376 arguments in command replies. All command functions should be
4377 updated to use this macro.
4379 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4381 * Minor typo fixes on command reply handling on server.
4383 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4385 * Added silc_server_command_add_to_channel internal routine to add
4386 the client to the channel after router has created the channel and
4387 sent command reply to the server.
4389 * Added generic silc_server_send_command to send any command from
4392 * Use static buffer with ID rendering instead of duplicating data.
4394 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4396 * Fixed a channel user mode bug when joining to a channel server gave
4397 everybody channel founder rights, oops.
4399 * We mark ourselves as the router of the incoming server connection
4400 if we are router ourselves. This way we can check in some packet
4401 sending functions whether it is locally connected server. For
4402 incoming router connections we put NULL.
4404 * For router sending packets locally means now always sending the
4405 packet cell wide; to local clients and local servers. For normal
4406 server sending packet locally means sending it to only local
4409 * Fixed the JOIN command to really work in router environment. If the
4410 channel is created it is always created by the router. Router is
4411 also responsible of making the initial joining to the channel,
4412 sending JOIN notify to the sending server and distributing
4413 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4414 does not exist server doesn't do anything else but forward the
4415 command to the router which performs everything.
4417 * Added silc_server_send_channel_key function to send the Channel Key
4420 * Added silc_server_create_channel_key to create new channel key. The
4421 channel key is now re-generated everytime someone joins or leaves
4422 a channel, as protocol dictates. Note: channel->key_len is the
4425 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4427 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4428 packet_receive.[ch] to separate packet sending and receiving
4429 routines. The server.[ch] now includes everything else including
4430 actual packet processing (writing and reading data) and other
4433 Renamed silc_server_private_message_send_internal to
4434 silc_server_send_private_message. The routine is still though
4435 used only to relay private messages as server does not send
4436 private messages itself.
4438 Renamed silc_server_new_channel to silc_server_create_new_channel
4439 and added new function sicl_server_new_channel that handles the
4440 incoming New Channel packet. Added also new sending function
4441 silc_server_send_new_channel to send New Channel Payload.
4443 * Added new function silc_server_notify to process incoming notify
4444 packet to the server/router. Server may then relay the notify
4445 to clients if needed.
4447 * Added new function silc_server_new_channel_user to process incoming
4448 New Channel User packet. Router will redistribute the packet and
4449 send JOIN notify to its local clients and locally connected servers
4450 if needed. Normal server will send JOIN notify to its local client
4451 on same channel when received this packet. Added also corresponding
4452 sending function silc_server_send_new_channel_user to sent the
4455 * Added boolean route argument to send_notif_to_channel and
4456 packet_send_to_channel functions to attempt to route the packet
4457 if it is TRUE and send only locally if it is FALSE.
4459 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4461 * silc_server_replace_id now broadcasts the received replace ID
4462 packet if it is not broadcast packet already. The router must
4463 broadcast to inform other routers about changed ID.
4465 * Added backpointer to server's router into SilcServer context in
4466 silcd/server_internal.h.
4468 * Fixed silc_server_packet_broadcast to send correct broadcast
4471 * The channel key is now distributed to the local client as soon
4472 as it is received from the router (in router environment) so that
4473 no other packet may be sent for the channel until client has
4476 * silc_server_remove_channel_user now broadcasts the received
4477 Remove Channel User packet if it is not broadcast packet already.
4478 The router must broadcast to inform other routers about removed
4481 * Added users field into SilcPacketContext that is a reference count
4482 of the context. One can increase the reference count by calling
4483 silc_packet_context_dup which is now changed to just increase the
4484 reference count instead of duplicating the data. The reference
4485 count is decresed by calling silc_packet_context_free that will
4486 free the data after the reference count hits zero.
4488 For now on the packet context and everything allocated into it
4489 (including the raw packet from network) must be freed by calling
4490 the new silc_packet_context_free function. Added also new function
4491 silc_packet_context_alloc that must be used now to allocate the
4492 context. This also means that if a routine is asynchronous from
4493 silc_[client/server]_packet_parse_type the packet context must
4494 be duplicated by calling silc_packet_context_dup. Otherwise it
4495 gets free'd after silc_[client/server]_packet_parse_type returns.
4496 Also, one must remember that if packet is duplicated then its
4497 reference count must be decresed by calling the free function as
4498 many times as it was duplicated.
4500 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4501 from both client and server.
4503 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4505 * Made joining to a channel working in router environment.
4507 * Cleaned up JOIN command on server side and create function
4508 silc_server_command_join_channel internal routine to make the
4511 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Changed silc_command_pending list to SilcDList. Also, added
4514 `ident' field to SilcServerCommandPending structure to identify
4515 the reply and to call correct callback.
4517 Added silc_server_command_pending_check function to replace the
4518 corresnponding macro. The silc_command_pending list is not
4521 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4522 to set identifier to previously allocated Command Payload. It
4523 is used to set identifier for command when resending Command
4526 * Added silc_command_payload_encode_payload to encode Command
4527 Payload buffer from SilcCommandPayload structure.
4529 * Added silc_argument_payload_encode_payload to encode Argument
4530 payload buffer from SilcArgumentPayload structure.
4532 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4534 * Changed WHOIS command to support router connection on server side.
4535 The whois request is always sent to router unless the server is
4536 standalone server. After server has received the reply from the
4537 router will it send the reply to the client.
4539 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4540 broadcast received broadcast packet. The function is used only
4541 by router. The broadcast packet is always sent to the router's
4544 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4545 render given ID to printable string, for log files for example.
4547 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4549 * Made basic router to router connections working. At least they
4550 can now connect to each other but nothing really works the way
4551 they are supposed - yet.
4553 * Added new initiator token to RouterConnection configuration
4554 file in silcd/serverconfig.[ch]. It is used to tell whether we
4555 are the initiator to the remote router or whether we'll expect
4556 the other end to connect.
4558 * Moved registering of listener task to silc_server_init, hence
4559 the server starts listenning as soon as it is run, even if it
4560 does not have connections to other routers. Let's see how well
4563 * Changed default connection retry timeouts for more suitable in
4566 * Removed cipher and such arguments from silc_idlist_add_client
4567 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4568 Added new function silc_idlist_add_data to add the keys and stuff
4571 * Added SilcIDListData structure and added it to SilcClientEntry
4572 and SilcServerEntry as their first field in the structure. This
4573 way we can explicitly cast the ID entries to the SilcIDListData
4574 structure and get common data for the entries. In past, we had
4575 to first check what type of connection it is and then cast it to
4576 correct ID entry type. Now, we can directly cast the opaque
4577 pointer to the SilcIDListData (no matter what ID entry it actually
4578 is) and get the data needed.
4580 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4582 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4583 in some circumstances even if threre were timeout tasks, though not
4584 IO tasks, but tasks anyway. Now fixed.
4586 * Defined SilcServerConnection structure to hold connection specific
4587 stuff about directly connected servers and routers. The definition
4588 is currently in silcd/server_internal.h. I thought about having
4589 a bit more important role fro this struct but for now it is used
4590 only when connecting to other server (or router actually).
4592 * Added connecting retry support in server when connecting to
4593 router(s). The retry feature implement exponential backoff
4594 algorithm. Also, added SilcServerParams structure to hold default
4595 parameters for server. For now, it include these retry settings
4596 and are hard coded. After server is moded to be as Silc Server
4597 Library this structure will be more important.
4599 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4601 * Changed client librarys channel->clients table to SilcList and
4602 changed code accordingly.
4604 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4606 * Changed client's channel table to SilcList and changed code
4607 accordingly. Also changed SilcChannelClientEntry to include back-
4608 pointer to the channel so that client entry can use that structure
4609 as list as well and we have fast cross-reference to the channel.
4610 This change dramatically decreased the complexity of channel
4611 handling with client entry and vice versa (removed one extra
4612 loop when searching for channel entry from many functions).
4614 * Changed server->sim from table to SilcDList and changed code
4617 * NAMES command can now be used from user interface. It will show
4618 the user list on the channel, neatly.
4620 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4621 Code now saves realname of the user if it becomes available.
4623 * Renamed configure.in to configure.in.pre and made ./prepare
4624 script to automatically add correct version string to
4625 configure.in which it creates from configure.in.pre.
4627 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4629 * NAMES command reply now shows users mode with the nickname when
4632 * Moved silc_client_ch[u]mode[_char] functions from
4633 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4634 place sucks, they are utility functions and should be in some
4637 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4639 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4642 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4646 * Added TRQ (efficient deque and list library) into lib/trq. This is
4647 a very good list library that is currently used in the SILC. Defined
4648 SilcList API over the library because I didn't like the API very
4649 much. See lib/trq/silclist.h for the API and examples of how to
4650 use the API. Fixed various places in the code to use the new
4651 SilcList API. The SilcList is meant for lists that has a structure
4652 already defined as a list. It is not suitable to add just some
4653 context to the list (in TRQ, the context is the list actually).
4655 So, I defined SilcDList that can be used for the purpose where
4656 predefined list structure does not exit. This can be used as
4657 such list. Now some context just can be added to the SilcDList.
4658 Currently this list is not used in the SILC just yet, though there
4659 are a lot places where this can replace dynamically allocated
4660 tables and I will fix these places, later, to use SilcDList.
4661 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4662 and use TRQ internally).
4664 Also fixed some annoying warning messages that the original TRQ
4665 code generated. Also minor changes to TRQ's Makefile.in.
4667 * Added support for querying by Client ID to both WHOIS and
4668 IDENTIFY commands into server, as required by the protocol.
4670 * Removed method function pointers from SilcBuffer structure. They
4671 weren't used to anything and just increased the context size for
4672 no good reason. This change also made silc_buffer_alloc and
4673 silc_buffer_free functions inline functions.
4675 * Disabled command flooding detection support until it's fixed so
4676 that it accepts commands in but does not execute them more than once
4679 * Added silc_net_localhost(), to return local hostname, into
4680 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4681 that must be initialized before calling silc_client_init.
4683 * Added new function: silc_server_send_notify_on_channels to send
4684 notify messages to all channels client has joined. It is assured
4685 that the message is sent only once per client.
4687 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4688 lib/silcutil/silcutil.[ch] as silc_format function. The new
4689 function is generic and is used by server as well, not only by
4690 the logging routines.
4692 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4693 the provided version string was not acceptable. Added new function:
4694 silc_ske_check_version into lib/silcske/silcske.h. The function
4695 must be implemented by the application (client or server) and it
4696 does not reside in the SKE library. The function checks the version
4697 string remote end sent.
4699 * Added back pointers (to opaque context and to SilcSocketConnection)
4700 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4702 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4703 duplicate packet context structure.
4705 * Changed `notify' client operation to send same arguments as client
4706 receives from server except for ID's. ID's are mapped to correct
4707 ID entry and that is returned. Also, if channel entry is not sent
4708 by server but the notify is for channel the channel entry is sent
4709 to application (otherwise application doesn't know that it is for
4710 channel (library gets it from packet's Destination ID)).
4712 * Added silc_client_remove_from_channels into client library to
4713 remove a client from all channels it has joined to. Used when
4714 received SIGNOFF notify from server. Added also new function
4715 silc_client_replace_from_channels to replace old ID entry with
4716 new ID entry on all channels. Used when received NICK_CHANGE
4719 * Fixed ID Cache list handling in silc_idlist_get_client in
4720 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4721 to get (or query) client by ID.
4723 * Updated TODO list.
4725 * Added connection authentication status message defined by the
4726 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4727 support for these into the code in client and server side.
4729 * Added generic function silc_client_send_command to send any command
4730 with variable argument list. Application should use this function
4731 to send commands if the command functions provided by the library
4732 does not suite for the application's user interface needs.
4734 * Added new `failure' client operation. Application is notified about
4735 received failure packet if client is executing a protocol. In this
4736 case the protocol's execution has failed.
4738 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4739 is required by the protocol.
4741 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4742 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4745 * Added status flag to SilcSKE object to indicate realtime status
4746 of the SKE protocol.
4748 * Application receives now exactly same command reply arguments as
4749 the library receives from server. However, if ID is received the
4750 corresponding ID entry is returned to the application (eg. Client
4751 ID is mapped to correct SilcClientEntry entry and that is returned).
4752 Changed command_reply client operation due to this change.
4754 * Changed all ID's in commands and in command replys as ID Payloads.
4755 Change affected both client and server side codes.
4757 All ID's sent in SILC network (with execption of ID's in SILC
4758 Packet header) are sent in ID Payload to support variable length
4761 * Server now notifies nick changes and notifies all clients on
4762 the channels about the new nickname (about the new Client ID,
4765 * Implemented CMODE command to change channel modes. Supports all
4766 channel modes defined by the protocol specs except ban and invite
4767 lists. (Also, private channel key mode is supported but support for
4768 setting private channel key in client is missing, thus, this mode
4769 has no effect on client side (except that server requires that the
4770 client uses private channel key and normal channel traffic does not
4773 Also, invite mode works per se, but INVITE command does not work
4774 yet correctly, so you can set channel as invite only channel but
4775 inviting clients to the channel does not work (it is yet to be
4776 thought what's the best way to do it).
4778 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4779 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4780 Implemented CUMODE command to change user's mode on the channel.
4781 Supports all modes defined by the protocol specs.
4783 * Added NAMES command reply to return users modes on the channel.
4785 * Removed unnecessary and slow ciphers from lib/silccrypt.
4787 * Set SO_KEEPALIVE option to connection sockets by default.
4789 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4791 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4792 redefined the Notify Payload into protocol specs.
4794 * Added silc_id_payload_parse_id to get ID directly from raw
4797 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4799 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4800 accept searching by Client ID as well.
4802 * Added support for LEAVE and SIGNOFF notify types in client library.
4804 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4805 to parse ID Payload from raw data.
4807 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4809 * Added flags parameter into silc_ske_assemble_security_properties
4810 function in lib/silcske/silcske.[ch].
4812 * Changed notify client operation to fit better for notify messages
4813 sent by server. The notify payload received from server is now
4814 passed to the application (after parsing it to SilcNotifyPayload).
4815 It is application's responsibility to retrieve the arguments
4816 from the payload and show the message the way it wants. The message
4817 sent by server is implementation specific.
4819 * Changed public keys to comply with the protocol specification.
4820 Old public keys are not supported anymore and are not compatible.
4822 * Removed nickname from Channel Payload as the latest draft removed
4823 it. The client must resolve the nickname from the NAMES command
4824 reply received when it joined the channel.
4826 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4828 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4830 * Fixed some errors in protocol specification drafts.
4832 * Created lib/silccore/silcnotify.c to implement Notify Payload
4833 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4834 generic payloads described by protocol specifications. The file
4835 includes implementations for ID Payload and Argument Payload.
4837 * Changed Command Payload implementation to use the new Argument
4838 Payload. Changed command_xxxx_payload to command_payload_xxxx
4839 to comply with SILC coding conventions.
4841 * Added suppport for Argument Payload handling in Notify Payload
4842 implementation as protocol requires it. Added the new support
4843 into server and client lib as well.
4845 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4847 * Added support for multiple nicknames on same channel. [n] is
4848 added locally to the nickname if there are more than one same
4849 nicknames on the channel.
4851 * Server now sends all nicknames that matched WHOIS request.
4852 Client also shows the list received from server.
4854 * Added TOPIC command to client side. User can now set and show
4855 current topic on channel.
4857 * Added MOTD command to client and server. Also, server sends the
4858 motd when client connects to the server.
4860 * Changed version strings to comply ISO 8601.
4862 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4864 * Fixed protocol error handling in client library. It should now
4865 cope even if the SKE fails for some reason.
4867 * Made new protocol specification drafts for submitting to IETF.
4869 * Implemented TOPIC command to server in silcd/command.c.
4871 * Added two new notify types into lib/silccore/silcnotify.h:
4872 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4873 notify nickname change and topic setting/change on a channel.
4875 * API change of command_reply operation in client library. The
4876 application gets now the status type received from server as well.
4878 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4880 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4882 * Cras fixed and optimized the packet handling even further and
4883 it should work now. Minor change to the prototype of function
4884 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4886 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4888 * Added new function into lib/silcutil/silcschedule.[ch]:
4889 silc_schedule_with_fd to select() a specified fd. The function
4890 returns after timeout expires or data arrives or goes. The
4891 function is used by packet routines to wait that all data is
4892 received from network.
4894 * Fixed data reading from network in lib/silccore/silcpacket.c.
4895 The code now assures that all data is read from the fd and then
4896 continues packet processing. This was a bug fix since the code
4897 used to drop some data in some circumstances.
4899 * Added new function into lib/silcclient/client.[ch]:
4900 silc_client_start_key_exchange to start key exchange after
4901 connection has been established to server. The code internally
4902 now uses this funtion but its main purpose was to provide it
4903 for applications that perform their own connecting. After
4904 application has created a connection it merely calls this
4905 function to start the key exchange between client and server.
4906 The library takes care of everything else after that.
4908 Updated also lib/silcclient/README to explain the usage of
4911 * Do not send to application information that connection has
4912 been established. Application gets notified it by connect
4915 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4917 * Applied cras's patch to add silc_schedule_one function. The
4918 function runs scheduler once and returns.
4920 * Fixed the scheduler after cras messed it up. The timeout
4921 handling works now as it's supposed to work.
4923 * Added into lib/silccore/ silcnotify.h to include notify
4924 message types support. Changed silc_server_send_notify*
4925 functions, in server.[ch], to support those new notify types.
4926 Added the support for the notify types into client library,
4927 as well. Added new notify client operation into ops.h in
4930 * Changed silc_server_packet_send_to_channel to send normal
4931 packets instead of just channel message packets. The function
4932 is now used to send the notify packets to channels. It is not
4933 used to send channel message packets anymore, as server never
4936 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4937 va_arg()s as it seems to require it nowadays. I guess, if SILC
4938 is compiled with older va_arg() the new code should work anyway.
4940 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4942 * Splitted core library. Core library (lib/silccore) includes
4943 now only SILC protocol specific core (and common) components.
4944 Created new utility library (lib/silcutil) that includes more
4945 generic purpose stuff. The stuff for util library was taken
4946 from the old core library. This was minor and easy split.
4948 * Created SILC Client Library (lib/silcclient) that includes
4949 implementation of the SILC client without user interface. This
4950 was major move from silc/ directory. The code has been changed
4951 so that it is transparent towards the user interface. The
4952 silc/ directory includes now the same user interface as before
4953 and it uses the new client library. Read lib/silcclient/README.
4954 Basicly, the client library performs everything else related
4955 to SILC except user interface handling. Also, configuration
4956 files are considered to be part of user interface and library
4957 does not handle them.
4959 This change also changed a lot of structures, function naming etc.
4960 Most important change was that SilcClientWindow object was
4961 renamed to SilcClientConnection in the client library. Created
4962 also new file lib/silcclient/ops.h. Also added new files
4963 silc/local_command.[ch] and silc/client_ops.[ch].
4965 All these changes were made to make it easier for user interface
4966 designers to create what ever user interface for the SILC client
4969 It is also expected that the server will be moved to lib
4970 directory as well and SILC Server Library will be created;
4971 sometimes in the future.
4973 * Removed Local commands from lib/silccore/silccommand.h as
4974 they are application specific and new client library does not
4975 handle any of those anymore.
4977 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4978 old client implementation in silc/.
4980 * Added support for callback functions in SILC_LOG_* macros.
4981 Application can now set its own callbacks that will be called
4982 instead of using the default functions that will always print
4983 the debug messages to stderr (or stdout). Also, debugging can
4984 now be disabled by setting silc_debug to FALSE and re-enabled by
4985 setting it to TRUE. Note, that logging will still work even
4986 if debugging is disabled.
4988 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4989 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4990 silc_log_reset_debug_callbacks.
4992 * To enable debugging in silc client one must give now -d
4993 option on command line.
4995 * Changed silc_schedule_init to automatically allocate task queues
4996 if they are not allocated before calling it.
4998 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5000 * Added GMP 3.1 into math library.
5002 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5004 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
5005 a channel in SILC network. The packet is used by servers and
5006 routers to notify other routers that user has left a channel.
5007 This little feature was missing until now. Added the feature
5008 to protocol specification as well.
5010 Added functions: silc_server_send_remove_channel_user and
5011 silc_server_remove_channel_user into server.[ch].
5013 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
5014 lib/silccore/silcpacket.h. However, they are not implemented
5017 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Fixed joining to a channel and sending channel messages
5020 between server and router. The channel message sending should
5021 now work inside a cell.
5023 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5025 * Fixed the private message sending between server and router.
5026 The private message sending should now work inside a cell.
5028 * Added silc_server_replace_id into server.[ch] to replace
5029 existing ID in the SILC network.
5031 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
5032 and silc_idlist_replace_server_id into idlist.[ch] in server.
5034 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5036 * Fixed the server to server connections. Server can again now
5037 connect to router. Router to router connections probably does
5040 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5042 * Added dynamic protocol registering support. Now protocols can
5043 registered and unregistered on the fly. Patch by cras.
5045 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5047 * Added lib/contrib directory to hold routines that some platforms
5048 don't have but are needed by SILC.
5050 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5051 into lin/contrib to provide getopt() and getopt_long() for
5052 those who don't have it.
5054 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5056 * Added AWAY command to client. When away message is set and
5057 client receives a private message packet the client automatically
5058 replies to the sender with the away message.
5060 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5061 bug seemed to be the cause of recent problems when compiling
5064 * Added version detection support to SKE protocol specification
5065 and added the new changes to the SKE implementation as well.
5066 There were other minor changes in the SKE protocol as well.
5068 Many changes in lib/silcske/silcske.[ch] and in
5069 lib/silcske/payload.[ch].
5071 * Added ^U functionality, clear input line. Patch from cras.
5073 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5075 * Mainly small bugfixes on core library. Fixed some debugging
5076 logging and buffer overflow in silclog.c.
5078 * Updated config.sub and config.guess on the distribution tree.
5080 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5082 * Added command lagging support in server. Client may execute
5083 commands now only once in two seconds.
5085 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5087 * Optimized packet reception. MAC computation and checking is now
5088 also more optimized. A lot previously duplicated code is now
5089 used as generic by both client and server.
5091 * Fixed key pair generation in clientutil.c
5093 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Added into lib/silccore/silcbufutil.[ch] new function;
5096 silc_buffer_realloc.
5098 * Moved generic packet sending/encryption functions to
5099 lib/silccore/silcpacket.[ch] from client and server. Some
5100 rewriting of the functions.
5102 * Moved all generic packet reception/decryption functions to
5103 lib/silccore/silcpacket.[ch] from client and server. The
5104 packet processing is now much cleaner in both client and server.
5105 These were major changes in both client and server.
5107 * Created many common functions in server to do packet sending.
5108 Previously code were duplicated a lot, this has been removed
5111 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5113 * Rewrote major parts of the ID cache system. Don't know
5114 whether it is better now or not but at least the API is more
5117 * Major rewrite on ID cache stuff on client because of the ID
5118 cache API changes. Added idlist.c to client.
5120 * Also major rewrite on ID cache stuff on server as well.
5121 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5122 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5123 in hand, instead they are all put into the ID cache system now.
5124 All server_idlist_* routines uses ID cache now instead of
5125 traversing its own lists (those lists does not exist anymore).
5126 SilcIDList though still exists. Also, SilcXXXEntry's are
5129 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5131 * Finally made the SKE implementation compliant to the protocol
5132 specification. All mp integers are now binary encoded as
5133 opposed being HEX encoded.
5135 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5138 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5139 functions: silc_[encode/decode]_pem. Also added function
5140 silc_encode_pem_file to PEM encode with newlines ('\n') for
5143 * SILC public keys are now encoded either PEM or binary. Same
5144 option is for private keys as well. By default private keys
5145 are binary encoded and public keys PEM encoded. Silly HEX
5146 encoding were removed.
5148 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5149 function to create fingerprints.
5151 * Fixed a bug in SHA1; does not change the original data anymore.
5153 * Partly implemented INFO command on client and server side.
5154 Fixed CLEAR command. Changes to SERVER command; show current
5155 server(s) when giving command without arguments. Added
5156 VERSION command to client.
5158 * Added check to server that unregistered connections cannot
5159 execute commands (unless it is specificly allowed).
5161 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5163 * Fixed screen refresh.
5165 * Fixed channel joining bug from client. On some circumstances
5166 client tried to join to a channel it had already joined.
5168 * Added public key verification process into client's protocol.c.
5169 The client now verifies the public key from user and saves
5170 it into ~./silc/serverkeys/ directory.
5172 Added into: clientutil.[ch]: silc_client_verify_server_key.
5174 * Changed SKE protocol's silc_ske_initiator_finish function
5175 to accept callback function that verifies the received public
5176 key. Removed old silc_ske_verify_public_key function.
5178 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5180 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5181 silc_pkcs_private_key[_data]_set.
5183 * Made the password and public authentication more cleaner in
5184 server's protocol.c.
5186 * Removed historic and obsolete protocol `channel_auth' from
5187 both client and server.
5189 * Removed wrong way of sending command status messages from
5190 server to client in server's command.c. The old way violated
5191 protocol specification.
5193 Changes to silccore/silccommand.[ch]: removed
5194 silc_command_encode_status_payload -> not needed anymore,
5195 changed silc_command_encode_payload_va to accept extra
5196 argument on variable argument list. The argument type must
5197 now be provided to the function. Also, added new function:
5198 silc_command_encode_reply_payload_va which is same as
5199 normal command_encode_payload_va except command status type
5200 is provided as extra argument.
5202 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5204 * Added ~./silc directory handling. The directory includes the
5205 public and private keys for the client.
5207 Added silc_client_check_silc_dir, silc_client_create_identifier
5208 and silc_client_load_keys.
5210 * Implemented SILC protocol compliant public key. Added public
5211 and private key saving to and loading from files.
5213 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5214 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5215 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5216 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5217 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5219 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5220 silc_pkcs_load_[public/private]_key.
5222 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5224 * Added silc_server_get_route (route.[ch]) to get connection
5225 data for the fastest route for given ID.
5227 * Implemented INVITE command on client and server. The command
5228 were re-defined in the SILC Protocol Specification and the
5229 implementation now complies with the specification.
5231 * Implemented PING command on client and server.
5233 * Implemented NAMES command on client and server. The server side
5234 supports currently only normal server not router server yet.
5235 Some changes to NAMES definition in SILC protocol specification.
5237 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5239 * Implemented LEAVE command on client and server.
5241 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5242 again. This change was made to the protocol as well. Server
5243 should not violate the protocol specification anymore.
5245 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5247 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5248 was tested. SOCKS4 was not but should work anyway.
