3 * Check that the public key exists in the GETKEY command before
4 trying to encode it. Affected file silcd/command.c.
6 * Print some notifications on received public keys with GETKEY
7 command in the Irssi SILC Client. Affected files are
8 irssi/src/fe-common/silc/module-formats.[ch],
9 irssi/src/silc/core/client_ops.c.
11 * Use IDENTIFY command to resolve the server information in the
12 GETKEY command instead of INFO command. Affected file
13 lib/silcclient/command.c.
15 * All command reply functions in the client library now calls
16 the pending command reply callbacks even if an error has
17 occurred. The server has done this a long time and now it was
18 time to move the client library to this as well. Now all
19 errors can be delivered back to the pending command reply
20 callbacks if necessary. Affected files are
21 lib/silcclient/command[_reply].[ch].
23 * Change the nickname on disconnection back to the username
24 because in reconnect the server will enforce it to it anyway.
25 Affected file irssi/src/silc/core/silc-servers.c.
27 * Fixed a config file parsing bug in the Irssi SILC client.
28 Affected file irssi/src/silc/core/clientconfig.c.
30 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
32 * When printing the channel mode on JOIN, verify that the
33 channel key and channel's HMAC are valid. Affected file
34 irssi/src/silc/core/client_ops.c.
36 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
38 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
39 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
40 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
42 * Removed channel key rekey task deleting from the function
43 silc_server_save_channel_key. Affected file silcd/server.c.
44 Added explicit timeout task context instead that is used to
45 delete the task if we are registering a new task before the
48 * When channel key rekey occurs the client library now saves
49 the old channel key for a short period of time (10 seconds) and
50 is able to use it in case some is still sending channel
51 messages encrypted with the old key after the rekey. Affected
52 file lib/silcclient/[idlist.h|client_channel.c].
54 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
56 * Added check to the silc_server_new_id_real to not accept
57 new ID if it is the sender's own ID. Affected file is
58 silcd/packet_receive.c.
60 * Assure that we do not announce ourself or the one we've
61 sending our announcements when we're router and are announcing
62 servers to our primary router. Affected file silcd/server.c.
64 * Fixed silc_server_command_identify_check_client to assemble
65 correct WHOIS packet. It send corrupted WHOIS packet and
66 caused problem with router to router connections. Affected
69 Fixed also silc_server_command_whois_check the same way
70 as for the IDENTIFY command.
72 * Added new SilcIDListStatus to the server in the SilcIDListData
73 structure. The status now includes the current status of
74 the entry (like registered, resolved etc.). Affected file
75 silcd/idlist.[ch]. Defined a bunch of different status types
76 as well. This replaced the old boolean registered field as well.
78 Added resolve_cmd_ident field to the SilcClientEntry structure
79 too so that if the entry is for example being resolved so
80 another command may attach to the same pending command reply
81 without requiring to resolve the same entry again. This concept
82 should optimize the WHOIS and the IDENTIFY resolving under
83 heavy load by taking away unnecessary resolving for entries
84 that are being resolved already.
86 Added support for adding multiple pending commands for one
87 command idenfier. Affected file silcd/command[_reply].[ch].
89 * Fixed WHOIS and IDENTIFY save to remove the cache entry
90 before deleting the data. Otherwise the hash table will have
91 freed data in comparison functions. Affected file is
92 silcd/command_reply.c.
94 * Fixed silc_idlist_replace_client_id to add the new entry to
95 the cache with NULL nickname. Otherwise there will be invalid
96 memory as the nickname after the nickname is freed. Affected
97 file silcd/packet_receive.c.
99 * Fixed the silc_idlist_get_clients_by_hash. The entries was
100 saved into wrong slots because the previous number of entries
101 was not taken into account. Affected file silcd/idlist.c.
102 Fixed same thing in silc_idlist_get_clients_by_nickname too.
104 * If we are router and we receive JOIN notify to a channel that
105 does not have any users then notified client is marked as the
106 channel founder, as it is it. The affected file is
107 silcd/packet_receive.c
109 * Added to the extended hash table API's table_del_*ext functions
110 the destructor as argument too, so that the caller can decide
111 which destructor to use or whether to use destructor at all.
112 Affected file lib/silcutil/silchashtable.[ch].
114 * Fixed ID Cache purging. It actually deleted the entries from
115 the hash table after the data was freed. The hash table ended
116 up comparing freed memory. The affected file is
117 lib/silccore/silcidcache.c.
119 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
121 * Fixed Irssi SILC client's KILL command's HELP syntax.
123 * The USERS command now resolves the detailed user information
124 if the userinfo field is missing. Affected file is
125 lib/silcclient/command_reply.c.
127 * Do not print error in silc_file_read if the read file does
128 not exist. Just silently return NULL. Affected file is
129 lib/silcutil/silcutil.c.
131 * Fixed the silc_log_output to not wine about NULL filename
132 and to not create some bogus " " filename. Affected file is
133 lib/silcutil/silclog.c.
135 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
137 * Fixed various printing bugs on the user interface in the
138 Irssi SILC Client. Minor changes that were forgotten from
141 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
143 * Fixed the configure.in.pre and the compilation and distribution
144 environment to support the new autoconf 2.52. That version is
145 now required to compile the CVS trunk.
147 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
149 * Renamed function silc_parse_nickname to silc_parse_userfqdn
150 to generally parse user@fqdn format strings. Affected file
151 lib/silcutil/silcutil.c.
153 * Added nickname_format and nickname_force_format fields to the
154 SilcClientParams structure. The first one defines the format
155 for the nicknames that the library will enforce if the receives
156 multiple same nicknames. The second one is boolean value and
157 can be used to force the library to always enforce the format
158 to the nicknames regardles whether there are multiple nicknames
159 or not. This configurable formatting was employed to flexibly
160 support accessing multiple nicknames from the user interface.
161 The userinterface can now set the nicknames to what ever format
162 they prefer. Affected file lib/silcclient/silcapi.h.
164 Added function silc_client_nickname_format to the file
165 lib/silcclient/idlist.c. It performs the nickname formatting.
167 Added new field `hostname´ to the SilcClientEntry context.
168 It holds the hostname of the client. Affected file is
169 lib/silcclient/idlist.h.
171 * Irssi SILC Client sets the nicknames in nick@hostn format.
172 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
173 irssi/src/silc/core/silc-core.c.
175 The WHOIS printing now also shows both the real nickname and
176 the formatted nickname so that user knows how to access the
177 user if there are multiple same nicknames cached. Affected
178 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
179 printing formatting too to take the hostname now as a separate
180 argument. The Affected file is
181 irssi/src/fe-common/silc/modules-formats.[ch].
183 * Changed the silc_client_get_clients_local to accept the formatted
184 nickname as argument. It accepts the real nickname too but the
185 formatted nickname can be used to find the true entry from
186 multiple entries. Affected file lib/silcclient/silcapi.h and
187 lib/silcclient/idlist.c.
189 * Added nickname_format_parse field to the SilcClientParams.
190 It is a callback function provided by the application to parse
191 the nickname out of the formatted nickname string. The library
192 calls it to get the nickname from the formatted string. Since
193 the application generally knows better the format of the nickname
194 string it parses it instead of the library, even though library
195 encodes the formatted string. If the callback function is not
196 provided then the library will use the string as is. The
197 affected file is lib/silcclient/silcapi.h.
199 * All the nickname strings passed to the client library in
200 commands are now expected to be formatted nickname strings.
201 If the command does not support the formatted nickname string
202 it will assume that the sent string is the actual nickname.
203 Affected file lib/silcclient/command.c.
205 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
207 * Added public key authentication support to OPER and SILCOPER
208 commands in the client library. Affected file is
209 lib/silcclient/command.c.
211 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
213 * Changed the get_auth_methdod client operation to be asynchronous.
214 It can be async if the application resolves the authentication
215 method from the server during the negotiation. Added new
216 SilcGetAuthMeth completion callback that the application will
217 call after resolving the authentication method.
219 Added function silc_client_request_authentication_method that
220 the application can use to resolve the authentication method
221 from the server. Added also SilcConnectionAuthRequest callback
222 that the library will call after the server has replied. The
223 application can call this function if it does not know the
224 current authentication method.
226 Affected files are lib/silcclient/client.c and
227 lib/silcclient/silcapi.h.
229 * The Irssi SILC client now automatically resolves the authentication
230 method incase any configuration information is not present (and
231 currently there never is). The affected file is
232 irssi/src/silc/core/client_ops.c.
234 * Fixed public key authentication from the client library.
235 Affected file lib/silcclient/protocol.c. Changed also the
236 protocol specification about the public key authentication in
237 the connection authentication protocol. The actual data to be
238 signed is now computed with a hash function before signing.
240 * Fixed the public key authentication from the server as well.
241 Affected file silcd/protocol.c.
243 * Removed the mlock()'s from the memory allocation routines.
244 Affected file lib/silcutil/silcmemory.c. The ./configure does
245 not check anymore for the mlock(). Affected file is
248 * Fixed USERS command in server to allow the execution of the
249 command for private and secret channels if the client sending
250 the command is on the channel. Affected file silcd/command.c.
252 * Fixed silc_client_get_clients_local to return the clients
253 count correctly. It could return wrong value. Affected file
254 lib/silcclient/idlist.c.
256 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
258 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
259 types. The assembler optimizations seemed not to like 64-bit
260 data types. The assmebler optimizations thus are now enabled
261 also for BSD systems as opposed to only enable them for Linux.
263 * Do not check for threads at all on BSD systems. Affected
264 file configure.in.pre.
266 * Removed -n and -h options from the Irssi SILC Client since
267 they are not used in silc.
269 * Fixed the prime generation to assure that the first digit
270 of the generated random number is not zero since our conversion
271 routines does not like number strings that starts with zero
272 digit. If zero digit is seen the random number is regenerated.
273 This caused some corrupted RSA keys when the zero first digit
274 was met. Affected file lib/silcmath/silcprimegen.c.
276 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
278 * Fixed WIN32 configuration in the ./configure script.
279 Fixed to include xti.h on environments that has it.
280 Patches by Carsten Ilchmann and andrew.
282 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
284 * Changed the silc_id_create_client_id to be collision
285 resistant. It is now assured that there cannot be created
286 two same client ID's. I suspect that some weird bugs in
287 the server were actually caused by duplicate Client IDs.
288 Affected file silcd/serverid.[ch]. A router receiving
289 new ID now also assures and informs the sending server
290 if the ID caused collision.
292 * Changed the silc_id_create_channel_id to also assure that
293 there are no collisions.
295 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
297 * Statement about ignoring the Mutual Authentication flag when
298 performing rekey with PFS was a bit misleading. It is ignored
299 if it was set in the initial negotiation, it cannot be even
300 set in the rekey. Fixed in the ke-auth draft. Started the
301 new versions of the protocol drafts in the doc/.
303 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
305 * Fixed a bug in silc_client_command_identify_save when saving
306 new channel information. The channel name was no duplicated
307 and caused crash on exit. Affected file is
308 lib/silcclient/command_reply.c.
310 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
312 * Fixed the getkey command handling in the server. Send just
313 empty OK reply to the sender if the key could not be fetched
314 (but everything else was ok, like the key just was not available).
315 Changed the public key parameter to optional in the protocol
316 specs so that empty OK reply can be sent. Affected file
319 Added a message to Irssi SILC client to tell to user if the
320 server did not return a public key.
322 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
324 * Fixed a channel key regeneration bug. It registered new
325 timeout tasks exponentially until all system resources were
326 used. Affected file silcd/server.c.
328 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
330 * Added the SILC Document generator to the scripts/silcdoc.
331 It can be used to generate the Toolkit Reference Manual out
332 of the source tree. Internally it will also use the RoboDoc
333 generator now imported in util/robodoc.
335 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
337 * Added couple of return's in rekey protocol if error orccurred
338 during the protocol. The execution must be terminated.
339 Affected file silcd/protocol.c. Also, terminate the protocol
342 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
344 * The client's Client ID was created initally from the wrong
345 nickname (it could have been in format nick@host) in the
346 silc_server_new_client. Affected file silcd/packet_receive.c
348 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
350 * Added some SILC_LOG_ERROR's to various error conditions
351 if client could not be added to ID cache. Affected files
352 silcd/packet_receive.c and silcd/server.c.
354 * When client's sock->user_data is freed, NULL also the
355 client->router and client->connection pointers. Added check
356 for these pointers being NULL to various places around the
357 code. Affected file silcd/server.c.
359 * Added client->data.registered == TRUE checks to various
360 places around the code to assure that unregistered client's
361 are not handled when it is not allowed. Affected file
364 * Added `bool registered' fields to all
365 silc_idlist_[server|client]_get_* routines to indicate whether
366 the fetched client needs to be registered or not. Affected
367 file silcd/idlist.[ch].
369 * Add your own entry as registered to the ID cache in the
370 server. Affected file server.c.
372 * Fixed a bug in silc_server_new_server. The SilcServer was
373 set as the new server's context instead of SilcServerEntry.
374 This naturally caused some weird bugs.
376 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
378 * Do not delete the channel rekey task when adding it
379 for in silc_server_create_channel_key.
381 * Changed the silc_server_create_channel_key to return
382 TRUE or FALSE to indicate the success of the channel key
385 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
387 * Fixed MSVC++ project files and added missing files to
388 Makefiles under win32/.
390 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
392 * Do not add TCP_NODELAY flag if the operating system
393 does not have it defined. Affected files are
394 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
396 * Fixed buffer overflow from Irssi SILC Client. Affected
397 file irssi/src/fe-common/core/themes.c.
399 * Fixed double free in client library in the file
400 lib/silcclient/client.c when disconnecting from server.
402 * Applied double free patch from cras to Irssi SILC client.
403 Affected files irssi/src/core/[modules/expandos].c
405 * Fixed the disconnection handling to Irssi SILC Client.
406 The application must call silc_client_close_connection
407 in ops->connect client operation in case of failure of
408 the connection. Affected file is
409 irssi/src/silc/core/client_ops.c.
411 * Do not set sock->protocol to NULL in the function
412 silc_client_close_connection after executing the protocol's
413 final callback since the sock might not be valid anymore.
414 Affected file lib/silcclient/client.c.
416 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
418 * Do not enable SILC_THREADS if the linking with libpthread
419 did not happen. Affected file configure.in.pre.
421 * Added notion to protocol specification that server must
422 verify the sent authentication payload with CMODE when
423 setting the channel founder key. Implemented it to the
424 server. Affected file silcd/command.c.
426 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
428 * Added _EXTRA_DIST SILC distribution variable to the
429 distributions file. It is used to conditionally add extra
430 files or directories to the specific distribution. Affected
431 files ./prepare, Makefile.am.pre and distributions.
433 Removed the `_' from the start of the distribution names.
436 * Added README.WIN32 for instructions to compile the Toolkit
439 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
441 * Fixed a double free in disconnection in the server. Affected
442 file is silcd/server.c.
444 * Fixed the lib/silcske/groups.c to work now also with GMP
445 MP library. The string conversion did not work when using
446 specific base and the base is indicated in the string as well.
448 * Created win32/ directory which now includes MSVC++ specific
449 stuff so that toolkit (DLLs) may be compiled with MSVC++.
450 It will appear only in the toolkit distribution
452 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
454 * Changed the key material distribution function in case when
455 the hash output is too short. The data is now concatenated
456 a bit differently than it used to. Made the change to the
457 SKE protocol specification.
459 * Added better GMP detection to configure.in.pre. A patch
462 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
464 * Fixed a minor bug in SKE that might cause some problem on
465 some platforms. Affected file lib/silcske/silcske.c.
467 * Added the cookie checking for initiator in the SKE. It checks
468 that the responder returns the sent cookie unmodified. The
469 affected file is lib/silcske/silcske.c. Added new SKE
470 error type INVALID_COOKIE that can be sent during the
471 negotiation. Fixed some memory leaks as well.
473 * Added the "invalid cookie" error message to Irssi SILC client's
476 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
478 * Added `task_max' field to the SilcClientParams to indicate
479 the maximum tasks the scheduler can handle. If set to zero,
480 default values are used. Affected file lib/silcclient/silcapi.h.
482 * Fixed memory leaks in silc_client_close_connection. Affected
483 file lib/silcclient/client.c.
485 * Added silc_client_del_client_entry to client library to free
486 all memory of given client entry. Affected file is
487 lib/silcclient/idlist.[ch].
489 * Added new functions silc_client_del_channel and
490 silc_client_del_server to delete channel and server entries.
491 Affected file lib/silcclient/[silcapi.h/idlist.c].
493 * Removed silc_client_del_client_by_id from silcapi.h.
495 * Fixed the INFO command to return the server's own info
496 correctly when querying by Server ID. Affected file is
499 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
501 * Removed the non-blocking settings in WIN32 code in the
502 silc_sock_[read/write] and added SleepEx instead. Affected
503 file lib/silcutil/win32/silcwin32sockconn.c. The availability
504 of input data is now checked with FIONREAD and ioctlsocket.
506 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
508 * Call silc_schedule_task_del_by_context in the
509 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
510 Affected file lib/silccore/silcprotocol.c.
512 * Call silc_protocol_cancel for active protocols in the
513 silc_server_close_connection if the funtion
514 silc_server_free_sock_user_data has not been called.
515 Affected file silcd/server.c.
517 * Generic tasks cannot be deleted using the del_by_fd
518 task deleting function since generic tasks does not match
519 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
521 * Added a notion to SILCOPER help file that the SILCOPER works
522 only on router server, not on normal server.
524 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
526 * Added for WIN32 support for the new scheduler as well.
527 Affected file lib/silcutil/win32/silcwin32schedule.c.
529 * Fixed the SHA1 implementation to work on various platforms.
531 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
533 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
534 API. It is part of the scheduler now. Everything else is
535 as previously but some functions has changed their names.
536 Checkout the lib/silcutil/silcschedule.h for the interface.
537 Updated all applications to use the new interface. Affected
538 files are lib/silcutil/silcschedule.[ch].
540 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
542 * Found a bug in the SKE implementation. The HASH value,
543 specified by the protocol, was not computed correctly. The
544 public key of the responder was not added to the computation
545 even though it is mandatory. Affected file lib/silcske/silcske.c.
546 This unfortunately causes incompatibilities with older
549 * Added WIN32 specific network init and uninit functions:
550 silc_net_win32_init and silc_net_win32_uninit to init and uninit
551 the Winsock2. Affected file lib/silcutil/silcnet.h and
552 lib/silcutil/win32/silcwin32net.c.
554 * Set the socket always to nonblocking mode on WIN32 after
555 reading data or writing data. Affected file is
556 lib/silcutil/win32/silcwin32sockconn.c.
558 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
560 * Fixed various compilation problems under WIN32. Affected
561 files lib/silcutil/win32/silcwin32thread.c and
562 lib/silcutil/win32/silcwin32schedule.c.
564 * Removed all _internal.h #includes from public header
565 files. Internal headers must never be included from
568 Removed also the lib/silcske/payload_internal.h file.
570 * All include files that may be needed (public and some others
571 included by the public headers) by application developers are
572 now copied to the ./includes directory. It does not copy any
573 internal headers. Affected file Makefile.defines.pre and all
574 Makefile.am's under lib/ and subdirs.
576 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
578 * Do not change the ~/.silc directory's permissions automatically.
579 Affected file irssi/src/silc/core/clientutil.c.
581 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
583 * Do not cancel the protocol in silc_server_close_connection
584 it might cause recursion. Now cancelled in the function
585 silc_server_free_sock_user_data. Affected file silcd/server.c.
587 * Fixed the silc_server_remove_clients_by_server to regenerate
588 the channel keys correctly finally. Added also new function
589 silc_server_remove_clients_channels to actually do it.
590 Affected file silcd/server.c.
592 * Fixed the silc_server_new_channel to not crash by giving
593 wrong router to the new channel. Affected file is
594 silcd/packet_receive.c.
596 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
598 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
599 which is given as argument to the silc_client_alloc now.
600 It can be used to configure the client and set various parameters
601 that affect the function of the client.
603 * The USERS command in server did not check whether the channel
604 is private or secret. Affected file silcd/command.c.
606 * Added new argument to the USERS command in protocol specification.
607 The USERS command now can take the channel name as argument
608 as well. Added support for this in client and server and
609 updated the protocol specs.
611 * Completed the GETKEY command in client. It can be now used
612 to fetch also servers public key not only some clients.
613 Affected files lib/silcclient/command[_reply].c.
615 * Added silc_client_get_server to return server entry by the
616 server name. Affected files lib/silcclient/silcapi.h and
619 * Redefined the IDENTIFY command in protocol specification to be
620 more generic. It now can be used to query information about
621 any entity in the SILC Network, including clients, servers and
622 channels. The query may be based either the entity's name
623 or the ID. Added support for this in both client and server.
625 Affected files silcd/command.c and lib/silcclient/command.c
628 * Optimized the WHOIS and WHOWAS commands in the server. Removed
629 the _from_client and _from_server functions. Affected file
632 * Added silc_client_get_channel_by_id_resolve to the file
633 lib/silcclient/silcapi.h to resolve channel information by
634 its ID. Added also silc_client_get_channel_by_id that
635 does not resolve it from the server.
637 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
639 * Added SilcServerEntry context into the client library
640 to represent one server. The INFO command now allocates
641 these to save the resolved server info. For now on the
642 client library will also keep information about servers,
643 connected and resolved with INFO.
645 The INFO command now allocates the SilcServerEntry context
646 and saves the server info there. The COMMAND_REPLY in
647 the INFO now returns the parameters to application in
648 same order as defined in the protocol specification.
650 The entries are cached in the client->server_cache.
652 * The INFO command is now issued after received the Client ID
653 from the server. Affected file lib/silcclient/client.c.
655 * The CMODE_CHANGE notify may now return also an SilcServerEntry
656 to the application as the mode changer might be server.
657 It is guaranteed that NULL is not returned anymore to the
658 application. Affected file lib/silcclient/client_notify.c.
660 The ID Type is now also passed to the application so that
661 it can check whether the returned entry is SilcClientEntry
664 Added new function silc_client_get_server_by_id to return
665 the server entry by ID. Affected files are the
666 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
668 * Do not create the channel in the Irssi SILC Client when issuing
669 the JOIN command but when received the sucessful JOIN command
670 reply. Otherwise the channel might get created even though we
671 could not join it. The Affected file is
672 irssi/src/silc/core/[silc-channels.c/client_ops.c].
674 * Fixed a channel joining bug in router. The router must also
675 check the channel modes, invite and ban lists etc. when serving
676 the JOIN command sent by normal server. Affected file is
677 silcd/command.c. The router now resolves the client's
678 information from the server who sent the JOIN command if it
679 does not know it, and processes the JOIN command only after
682 * Changed the SilcCommandCb to take new argument; void *context2.
683 Affected file lib/silccore/silccommand.h
685 The second argument in the command callbacks in the server now
686 includes the SilcServerCommandReplyContext if the command was
687 called as pending command callback from the command reply.
688 Otherwise it is NULL. When called as pending the status of the
689 command reply will be checked and if it was erronous the
690 error will be sent to the original sender of the command.
691 This way the client always receives the error messages even
692 though the server was actually the one who received the error
693 when it resent the command to router, for example. Affected
694 files silcd/command[_reply].[ch].
696 * Fixed sending WHOWAS command's error message to client if
697 the requested client could not be found. It was missing.
700 * Changed the CMODE and CUMODE commands reply arguments in the
701 protocol specification. The Channel ID is now sent in both
702 of the commands to identify the channel. Implemented this
703 new feature to the client and server. Affected files
704 lib/silcclient/command_reply.c and silcd/command.c.
706 * Made better checks for invite and ban lists in the JOIN
707 command in server. Affected file silcd/command.c.
709 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
711 * The server now performs the incoming host IP/DNS lookup
712 using the silc_socket_host_lookup and thus does not block
713 the server anymore. Affected file silcd/server.c.
715 * Completed the multi-thread support for SILC Scheduler in
716 the lib/silcutil/silcschedule.c.
718 * Fixed the configure.in.pre to detect the pthread correctly
721 * Fixed a deadlock in silc_task_queue_wakeup in the file
722 lib/silcutil/silctask.c.
724 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
726 * Added new function silc_schedule_wakeup that is used in
727 multi-threaded environment to wakeup the main thread's
728 schduler. It needs to be used when a thread adds a new task
729 or removes a task from task queues. After waking up, the
730 scheduler will detect the task queue changes. If threads
731 support is not compiled in this function has no effect.
732 Implemented the wakeup mechanism to both Unix and WIN32
733 systems. Affected files are lib/silcutil/silcschedule.[ch],
734 lib/silcutil/unix/silcunixschedule.c and the
735 lib/silcutil/win32/silcwin32schedule.c.
737 * Added new function silc_task_queue_wakeup to wakeup the
738 scheduler by the specified task queue. Affected file
739 lib/silcutil/silctask.[ch].
741 * The silc_socket_host_lookup_start now wakes up the scheduler
742 after adding the timeout task. Affected file is
743 lib/silcutil/silcsockconn.c.
745 * The silc_socket_host_lookup is synchronous now if the threads
746 support is not compiled in. However, the callback is still
747 called asyncronously through the scheduler, anyway. Affected
748 file lib/silcutil/silcsockconn.c.
750 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
752 * Added new function silc_socket_host_lookup to perform
753 asynchronous IP and FQDN lookups for the socket connection.
754 Affected files lib/silcutil/silcsockconn.[ch].
756 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
758 * Added SILC_MUTEX_DEFINE to define the mutex on environments
759 that may or may not compile the mutex support in.
761 Changed the silc_mutex_alloc interface. It allocates the
762 mutex now to the sent pointer and returns TRUE or FALSE.
764 Affected file lib/silcutil/silcmutex.h.
766 * Wrote the SILC Task Queue interface to support multi-threads.
767 Affected file lib/silcutil/silctask.[ch].
769 * Wrote the SILC Scheduler to support multi-threads. Affected
770 file lib/silcutil/silcschedule.c.
772 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
774 * Implemented the SILC Mutex API and SILC Thread API for WIN32
775 in lib/silcutil/win32/.
777 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
779 * Defined SILC Mutex API and SILC Thread API and implemented
780 them for Unix. Affected files are
781 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
782 lib/silcutil/unix/silcunixmutex.c and
783 lib/silcutil/unix/silcunixthread.c.
785 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
787 * Fixed the silc_server_remove_clients_by_server's channel
788 key re-generation. The hash table handling was incorrect
789 and would not work with many channels. Affected file is
792 * Fixed some memory leaks around the server code.
794 * Rewrote the silc_server_get_users_on_channel to support IPv6
795 based Client ID's. Affected file silcd/server.c.
797 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
798 specification. However, a separate document must be written
799 to define the detailed signing procedure and the payload
800 associated with the flag. Defined the flag to the
801 lib/silccore/silcchannel.h as well.
803 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
805 * Changed the dynamic tables to static size tables in the
806 lib/silccrypt/silchmac.c.
808 * Removed GCC dependencies from the code. A patch by cras.
810 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
812 * Do not show the error "Error receiving packet bla bla"
813 in server if it really was not an error (-2 means that reading
814 is pending). Affected file silcd/server.c.
816 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
818 * Fixed a possible crash in silc_server_remove_clients_by_server
819 in silcd/server.c. Fixed there also some memory leaks.
821 * Fixed the silc_idlist_replace_client_id. It could replace
822 wrong key in the hash table. Affected file silcd/idlist.c.
824 * Do not check whether there are global users on the channel
825 if the channel->global_users is FALSE. Affected functions
826 silc_server_remove_from_one_channel and
827 silc_server_remove_from_channels in silcd/server.c. Also,
828 do not check if the removed client is local as we can be
829 sure that global client was not removed from the channel
830 and checking for global users is not needed.
832 * The silc_server_remove_clients_by_server now re-generates
833 the channel keys correctly for those channels that had
834 clients removed from them. Affected file silcd/server.c.
836 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
838 * Found the reason of random crashes in the server. We weren't
839 ignoring the SIGPIPE signal (which can be sent in write())
840 and it crashed the server. Affected file silcd/silcd.c.
842 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
844 * Assure that sock->user_data is not NULL in the function
845 silc_server_packet_send in silcd/packet_send.c.
847 * Disconnect the remote connection if it could not be added
848 to any ID lists in the server. The affected file is
851 * Check in silc_server_packet_send[_real/dest] that the
852 socket is not disconnecting and ignore the data if it is.
853 Affected file silcd/packet_send.c.
855 * Define inline to __inline on native WIN32 compilation.
856 Affected file includes/silcwin32.h.
858 * Added some explicit type casts for inline code since MSVC
859 require them. Affected files lib/silcutil/silcbuffer.h,
860 lib/trq/silcdlist.h and lib/trq/silclist.h.
862 * Print warning in log files from now on if the packet
863 decryption fails. Affected file silcd/server.c.
865 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
867 * Changed the `say' client operation's interface to accept
868 new `type' argument to indicate the type of the message sent
869 by the library. The application may filter the library's
870 messages according the type. The affected file is the
871 lib/silcclient/silcapi.h.
873 * Added two new functions to lib/silcclient/silcapi.h:
874 silc_client_del_client and silc_client_del_client_by_id.
875 Affected file lib/silcclient/idlist.c.
877 * Moved the clientincludes.h from includes/ to silc/ and
878 serverincludes.h from includes/ to silcd/.
880 * The modes for the CMODE and CUMODE are now passed as
881 uint32 for application with COMMAND_REPLY. The affected
882 file is lib/silcclient/command_reply.c.
884 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
886 * /WHOIS without arguments shows client's own information.
887 Affected file lib/silcclient/command.c.
889 * Changed PING to not accept any arguments. The specs
890 says that client can ping only the connected server so
891 requiring an argument is not needed. Affected file is
892 lib/silcclient/command.c.
894 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
896 * Fixed a fatal bug in private message sending and reception
897 encryption and decryption when using private message keys.
898 The implementation was incorrect and did not follow the
899 specification. It causd that some of the message were
900 lost since it did not use the sending and receiving keys
901 as the protocol suggests. This has been fixed and will cause
902 incompatibilities with older clients when sending private
903 message encrypted with private message keys. Affected files
904 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
905 and various other in Irssi SILC Client.
907 Added `responder' boolean argument to the functions
908 silc_client_add_private_message_key[_ske] to indicate when
909 the key is added as responder or initiator of the key
912 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
914 * Removed the silc_ske_check_version function and created
915 a SilcSKECheckVersion callback. Added also a function
916 silc_ske_set_callbacks that is now used to set all SKE
917 callbacks. The callback functions are not given to
918 the SKE functions anymore, but this function is used to
921 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
923 * Added `silc_version' argument to the silc_client_alloc
924 to define the version of the application for the library.
925 The library will use the version string to compare it
926 against the remote host's (usually a server) version
927 string. Affected file lib/silcclient/silcapi.h
929 * Added the KE protocol context to Key Agreement context
930 in client library so that we can abort the SKE if it
931 is in process when we get timeout. Affected file is
932 lib/silcclient/client_keyagr.c.
934 * Do not resolve the client ID forever if it returns in the
935 first time that such client does not exist. This was done
936 for example with private message. Affected file is
937 lib/silcclient/client_prvmsg.c.
939 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
941 * Do not add regex.h for WIN32. The affected file
942 includes/silcincludes.h.
944 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
945 not work yet 100%. It generates the DLL's automatically
946 when compiling with --with-win32 under cygwin.
948 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
950 * lib/contrib/regex.c is not compiled on WIN32.
952 * Added silc_net_get_socket_opt function to the
953 lib/silcutil/silcnet.h.
955 * Added includes/silcwin32.h for WIN32 specific includes
958 * Do not use ptime structure or any of the posix process
959 functions on WIN32 in lib/silccrypt/silrng.c.
961 * Added silc_gettimeofday to provide generic function
962 for struct timeval on all platforms. Added the function
963 to lib/silcutil/silcutil.h.
965 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
967 * Moved the lib/silccore/silcsockconn.[ch] to the utility
968 library as they clearly belong there. As a plus side we
969 can make the actual socket connection routines platform
972 Added also new generic function silc_socket_read and
973 silc_socket_write (that used to be silc_packet_[read/write].
974 The implementation of these are platform specific.
976 * Added WIN32 specific routines of silc_socket_[read/write]
977 to lib/silcutil/win32/silcwin32sockconn.c.
979 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
981 * Added preliminary support for native WIN32 compilation under
982 cygwin (using the -mno-cygwin option for GCC) to the
983 ./configure.in.pre. The --with-win32 now prepares the
984 compilation for native WIN32.
986 * Rewrote the SILC Scheduler interface in the file
987 lib/silcutil/silcschedule.h. The scheduler is now context
988 based and does not have anymore any global static scheduler.
989 Moved the Unix scheduler to the lib/silcutil/unix/ directory
990 and created lib/silcutil/win32 directory for WIN32 based
993 * Added Unix specific network routines to the
994 lib/silcutil/unix/silcunixnet.c and the old
995 lib/silcutil/silcnet.c includes now only generic routines.
997 Added WIN32 specific network routines to the
998 lib/silcutil/win32/silcwin32net.c.
1000 * Added Unix specific utility functions from the
1001 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
1003 * Added WIN32 SILC Scheduler to the file
1004 lib/silcutil/win32/silcwin32schedule.c. The code is of course
1007 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
1009 * Do not handle JOIN notify in the server if the target client
1010 is not registered (idata->registered == FALSE). The affected
1011 file is silcd/packet_receive.c.
1013 * Update the nickrec->founder in event_cumode in the Irssi SILC
1014 client. Affected file irssi/src/silc/core/silc-channels.c.
1016 * Fixed the CUMODE_CHANGE notify handling in the server when
1017 server and router are announcing their clients on channels.
1018 Now the mode changes are saved and notified correctly. The
1019 affected file is /silcd/packet_receive.c.
1021 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
1022 They really did not replace the cache entry in the ID Cache.
1023 Now they do that. Affected file silcd/idlist.c.
1025 * Fixed the KICK notify handling in the Irssi SILC client to
1026 update the channel records so that the kicked client does not
1027 appear to be on the channel. The affected file is
1028 irssi/src/silc/core/silc-channels.c.
1030 * Always update the conn->current_channel when executing command
1031 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
1033 * Fixed the KILL notify handling in Irssi SILC client to remove
1034 the killed client on all channels.
1036 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1038 * Fixed the silc_parse_command_line to remove extra spaces
1039 from the start and end of the arguments. Affected file is
1040 lib/silcutil/silcutil.c.
1042 * Cancel and free any active protocol in the function
1043 silc_server_close_connection. Affected file silcd/server.c.
1045 * Cancel and free any active protocol in the function
1046 silc_client_close_connction. Affected file is
1047 lib/silcclient/client.c.
1049 * Do not execute the KILL command for clients that are in
1050 history (ie. they are not in the network). Affected file is
1053 * Fixed KILL notify handling, client does not crash anymore.
1054 Affected file irssi/src/silc/core/silc-channels.c.
1056 * Reduced the default packet buffer size from 2048 to 1024 in
1057 lib/silccore/silcpacket.c.
1059 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
1060 counter to the SKE context that is incresed when the SKE library
1061 performs async operation outside the library. If the outside
1062 process frees the SKE context and FREED status will be set
1063 and the library will detect after the sync operation that the
1064 libary is freed. The affected files are
1065 lib/silcske/silcske[_status].[ch].
1067 * Resolve the client entry information in the function
1068 silc_client_channel_message to assure that NULL pointer is not
1069 passed as client entry to the application. */
1071 * Fixed the task timeout calculation to assure that there is
1072 never negative timeouts. The affected file is
1073 lib/silcutil/silcschedule.c.
1075 * Fixed the channel user mode notification sending in server.
1076 It was sent point-to-point to the router (or to server by router)
1077 but it needs to be destined to a channel. The routines now
1078 supports sending the channel user mode notifys to the channels
1079 when announcing clients and channels. Affected files are
1080 silcd/server.c and silcd/packet_receive.c.
1082 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
1083 It did not actually replace the old channel entry in the cache.
1084 Affected file lib/silcclient/client_notify.c.
1086 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1088 * Fixed a possible crash in silc_packet_send_prepare. It now
1089 assures always that there is enough space in the buffer and
1090 at the tail area of the buffer (for MAC).
1092 Fixed the inbound buffer reallocation in silc_packet_read.
1093 It was old code and did not handle the reallocation correctly.
1096 The affected file is lib/silccore/silcpacket.c.
1098 * Fixed buffer overflow in silc_parse_nickname in the file
1099 lib/silcutil/silcutil.c.
1101 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1103 * make install generates new server keys only if there is not
1106 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1108 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
1109 Added check that if the NOREPLY is set then we will not send
1110 the away message. This avoids infinite loop of away messages
1111 if both clients are away. The affected file is
1112 lib/silcclient/client_prvmsg.c.
1114 * Fixed client crash if /NICK was given without arguments.
1115 Affected file lib/silcclient/command.c.
1117 * Server does not send the invite list in INVITE command back
1118 to the client if the list was not altered. Added this notion
1119 to the protocol spec as well. Affected file silcd/command.c.
1121 Fixed possible crash in INVITE command by checking the
1122 value of silc_server_get_client_route command.
1124 * Fixed the INVITE notify type handling. The arguments are now
1125 taken in correct order and client does not crash. The affected
1126 file is irssi/src/silc/core/silc-channels.c.
1128 Removed the "Inviting xxx to channel" message from the
1129 client library away and let the application handle it.
1130 Affected file lib/silcclient/command.c. Added that message
1131 to Irssi SILC client's message formats.
1133 * Fixed CMODE command crash in client. It now checks the
1134 amount of arguments correctly and does not crash. The affected
1135 file is lib/silcclient/command.c.
1137 * Do not create new channel automatically in silc_channels_join
1138 but check whether the channel by that name already exists.
1139 Affected file irssi/silc/core/silc-channels.c.
1141 * Do not send the SERVER_SIGNOFF to router if the disconnected
1142 entity was the router. Affected file silcd/server.c.
1144 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
1145 SILC client as it was missing from there.
1147 Added the handling of the KICK notify to the Irssi SILC client
1148 as it was missing. Added "you have been kicked" message to
1149 Irssi SILC client's message modules formats.
1151 Added the handing of the KILL notify to the Irssi SILC client
1152 as it was missing. Added the kill message module formats
1155 The affected file is irssi/src/silc/core/silc-channels.c.
1157 * The router did not save the channel mode the server announced.
1158 Affected file silcd/packet_receive.c.
1160 * Fixed a possible crash in INFO command in server. If the
1161 server did not provide the server info it crashed. Affected
1162 file silcd/command.c.
1164 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1166 * Fixed the GETKEY command in the server to check also the
1167 global list. Otherwise the GETKEY would not work correctly
1168 in normal SILC server. Affected file silcd/command.c.
1170 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1172 * Fixed GETKEY crash, it crashed if the command did not succseed.
1174 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1176 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
1177 is now real and not just an macro interface to GMP.
1179 Removed the entire GMP from the source tree and imported new
1180 NSS MPI library instead. Reason for removing GMP is that it is
1181 extremely large and compiles extremely slow. The NSS MPI
1182 is only a few files and compiles in less than 10 seconds.
1183 The speed is also about the same as GMP. The MPI is imported
1184 to lib/silcmath/mpi.
1186 If the system has GMP installed we will still use the GMP.
1187 If it is not then the NSS MPI will be compiled.
1189 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1191 * Merged a long nickname (127 characters long) crash bugfix from
1192 Irssi CVS tree. Affected file irssi/src/core/misc.c.
1194 * Merged a freed memory reference bugfix from Irssi CVS tree.
1195 Affected file irssi/src/core/commands.c.
1197 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1199 * Added the server's public key sving and verification to the
1200 server when performing the SKE. This was missing and the
1201 remote server's (or router's) public key was accepted without
1202 checking whether we have it previously or trust it at all.
1203 Affected file silcd/protocol.c.
1205 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1207 * Check in the silc_server_timeout_remote if protocol is active
1208 and make sure that the protocol's final callback is called so
1209 that all memory if freed. Affected file silcd/server.c.
1211 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * silc_server_whois_send_reply crashed the server if the nickname
1214 was 127 characters long. Affected file silcd/command.c.
1216 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1218 * Added sanity check to the silc_server_new_client. If the hostname
1219 is provided inside username then check that the provided hostname
1220 really is the same as the resolved one. If the hostname was not
1221 resolved then check it from the public key. Affected file is
1222 silcd/packet_receive.c.
1224 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
1225 if the server disconnected us and the connection is not valid
1226 anymore. Affected file irssi/src/silc/core/silc-channels.c.
1228 * Moved the silc_client_[chmode|chumode|chumode_char] away from
1229 the library to the lib/silcutil/silcutil.[ch].
1231 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1233 * Close log file after open. Affected file
1234 lib/silcutil/silclog.c.
1236 * Check whether sock == NULL in silc_client_send_packet and return
1237 if it is. Affected file lib/silcclient/silcclient.c.
1239 * Check rec->entry == NULL in the Irssi SILC Client before
1240 sending the channel message. Affecte file is
1241 irssi/src/silc/core/silc-servers.c.
1243 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1245 * Merged a splitted window bugfix from Irssi CVS tree. The
1246 affected file is irssi/src/fe-text/textbuffer-view.c.
1248 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
1249 It did not print nickname.
1251 * Improved the distributions system a bit.
1253 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1255 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
1256 irssi/src/fe-text/gui-window.c.
1258 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
1259 to in-active server. The affected file is
1260 irssi/src/silc/core/client_ops.c.
1262 * Resolve the client in USERS command reply if the entry does
1263 not have username resolved. The affected file is
1264 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
1265 command to WHOIS command to really resolve stuff. The USERS
1266 is not used any more in any critical section so WHOIS can
1267 be used even though it might be slower than IDENTIFY.
1269 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
1272 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1274 * Changed the protocol API a bit more consistent in the
1275 lib/silccore/silcprotocol.[ch].
1277 * Changed the following headers to ROBODoc format:
1279 lib/silccore/silcpayload.h
1280 lib/silccore/silcprotocol.h
1281 lib/silccore/silcsockconn.h
1283 All core library headers are now formatted.
1285 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1287 * Fixed a bug in Irssi SILC client; do not show that you are
1288 server/router operator if you really are not. Affected file is
1289 irssi/src/silc/core/client_ops.c.
1291 * Renamed silc_command_free_payload to silc_command_payload_free.
1292 Affected file lib/silccore/silccommand.h
1294 * Added silcmath.h to include the prototoypes of various routines
1295 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
1298 * Changed the following headers to ROBODoc format:
1300 lib/silccore/silcchannel.h
1301 lib/silccore/silccommand.h
1302 lib/silccore/silcid.h
1303 lib/silccore/silcidcache.h
1304 lib/silccore/silcmode.h
1305 lib/silccore/silcnotify.h
1306 lib/silccore/silcpacket.h
1307 lib/silcmath/silcmath.h
1309 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1311 * Added checking to the server code not to start the server if
1312 ciphers and stuff are not configured properly. Affected files
1313 silcd/serverconfig.[h] and silcd/server.c.
1315 * Changed the layout of the header files of the public interfaces
1316 in the SILC libraries. The new layout supports ROBODoc
1317 documentation tool (and some others) so that it is easy to create
1318 a library reference manual. All the other headers and source
1319 code must still follow the CodingStyle document. Also source
1320 code must not include these ROBODoc stuffs, only the headers.
1321 Furthermore, all public interface headers must now be named
1322 by using `silc' prefix, example: silcapi.h, silccipher.h.
1323 Some files were renamed due to this. All the other headers
1324 must not be used as public interfaces. I will update the
1325 CodingStyle document later. Changed following headers, so far:
1327 lib/silcclient/silcapi.h
1328 lib/silccore/silcauth.h
1329 lib/silccore/silcprivate.h
1330 lib/silccrypt/silcdh.h
1332 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1336 * Removed silc_client_packet_send_flush from the client library
1337 as it is not needed. Affected file lib/silcclient/client.[ch].
1339 * Added printing of message of unresolved authentication method
1340 to the Irssi SILC client. Added it to the module formats.
1341 Removed the same message from the client library.
1343 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1345 * Added new distribution feature, DISTLABEL. Every distribution
1346 can define own preprocessor label that can be used in the
1347 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
1348 file distributions, acconfig.h.pre and prepare.
1350 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1352 * Added Makefile.defines_int to include the actual definitions
1353 for Makefile.defines.in. Tested the new distribution system,
1354 created distributions and tested installation.
1356 * Added AWAY message printing to the Irssi SILC client. Added
1357 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
1359 * Added SCONNECT command to call the SILC's CONNECT command.
1360 Cannot use CONNECT directly since Irssi uses that internally.
1361 Affected file irssi/src/silc/core/silc-servers.c.
1363 Added ACTION local command. It is same as ME command but takes
1364 the channel as mandatory argument.
1366 Rewrote some of the Irssi's help files to suite for SILC
1369 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1371 * Added Makefile.defines[.in] that should for now on be included
1372 in all Makefile.am file in the source tree. That file includes
1373 all common compilation definitions for SILC source tree.
1375 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1377 * Minor changes to the ./prepare script to change the package
1378 name according the distribution name to the configure.in.
1380 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1382 * Created new distribution system. Added file `distributions'
1383 that defines all the distributions that can be created out of
1384 the SILC source tree. The ./prepare script now reads that
1385 file to determine how to prepare the distributions. The
1386 first argument to the ./prepare is the name of the distribution
1387 and second is the version of the distribution. If given
1388 without arguments it creates the default (toolkit) distribution
1389 with the default version (defined in ./prepare).
1391 All Makefile.am files that are subject to the distributions
1392 are now named as Makefile.am.pre. These are ./Makefile.am
1393 and lib/Makefile.am. Others may be changed later.
1395 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1397 * Added invite list, ban list, some key management and connection
1398 error message printing to module formats in the Irssi SILC client.
1400 * Added new silc_client_set_away_message to set the away message
1401 that is back to the person who sent private message. The
1402 affected file lib/silcclient/silcapi.h and the
1403 lib/silcclient/client_prvmsg.c.
1405 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1407 * Fixed the private message sending in the Irssi SILC client,
1408 added local command KEY to the Irssi SILC client.
1410 Added key management and key agreement message formats to the
1411 irssi/src/fe-common/silc/module-formats.[ch].
1413 Added USERS (alias WHO) printing, server/router operator
1414 indication and LIST command printing to the module formats.
1416 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1418 * Fixed channel joining notify handling, cumode notify handling
1419 from Irssi SILC client.
1421 * Added SILC specific module-formats to the Irssi SILC client so
1422 that SILC specific message hilighting, colors etc is possible.
1423 Affected file irssi/src/fe-common/silc/module-formats.[ch].
1425 Added channel mode, channel user mode, actions, notices,
1426 whois and whowas printing to the the module-formats.c.
1428 * Fixed a bug in channel deletion in the server. The channel
1429 is not left to the cache even if the channel founder auth mode
1430 is set when there are no users anymore on the channel. Affected
1431 file silcd/server.c.
1433 * The silc_net_localhost now resolves the entire hostname including
1434 the domain name. Affected file lib/silcutil/silcnet.c.
1436 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1438 * Changed the ask_passphrase client operation to be ascynchronous.
1439 It has now a completion callback and a context that the
1440 application must call after it has got the passphrase from
1441 the user. Affected files lib/silcclient/silcapi.h,
1442 lib/silcclient/protocol.c, lib/silcclient/command.c and
1445 Added SilcAskPassphrase callback that the application calls
1446 to deliver the passphrase to the library.
1448 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
1449 The public key verification and especially a certificate
1450 verification is asynchronous procedure.
1452 Added new SILC_SKE_STATUS_PENDING status to indicate the
1453 request is pending and a callback will be called to finalize
1456 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
1457 indicate that remote end did not send its public key (or
1458 certificate), even though we require it. Added check for this
1459 condition in the SKE. This was a security bug, now fixed.
1461 Defined new SilcSKEVerifyCbCompletion callback that is called
1462 when the verification process is completed.
1464 The affected files lib/silcske/silcske_status.h and
1465 lib/silcske/silcske.[ch].
1467 * Changed the verify_public_key client operation to be async
1468 as well. Defined SilcVerifyPublicKey callback that is used to
1469 indicate the success of the public key verification process.
1471 Changed the server and client to use the new async client
1474 * Changed the Irssi SILC client's internal scheduler to be called
1475 twice as many times as it used to be. As a result the client
1476 should be a bit faster now. Affected file is
1477 irssi/src/silc/core/silc-core.c.
1479 * Added support to Irssi SILC client of asynchronous public key
1480 verification and passphrase inquiry. Affected file is
1481 irssi/src/silc/core/silc-core.c.
1483 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1485 * Do not say "You have left channel %s" in client library.
1486 Moved it to the application. Affected files are
1487 lib/silcclient/command.c and silc/client_ops.c.
1489 * Fixed silc_client_get_clients. Command context was not
1490 duplicated and was freed memory in the callback. Affected
1491 file lib/silcclient/idlist.c.
1493 * Do not say "you are now talking..." on JOIN command in the
1494 client library. The appliation must handle it.
1496 * Do not say ".. changed topic to" in command reply in the
1497 client libary. The application must handle it.
1499 * Fixed TOPIC command sending in the client library.
1501 * Fixed a memory leak in silc_client_command_free in the file
1502 lib/silcclient/command.c.
1504 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1506 * Imported a modified version of Irssi client to the source tree.
1507 The Irssi will be used to create a new client called
1508 Irssi SILC. Imported to irssi/.
1510 Added silc_core_init_finish function to the Irssi. Affected
1511 file irssi/configure.in.
1513 A lot changes in the Makefile.ams around the irssi tree.
1515 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1517 * Do not rehash if the new size is same as the old size of the
1518 hash table, in the silc_hash_table_rehash*. The affected file
1519 lib/silcutil/silchashtable.c.
1521 * Replaced hash_table_del_by_context calls from the server
1522 (when channel->user_list and client->channels) to the
1523 hash_table_del as it is sufficient and faster.
1525 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1527 * Added silc_hash_table_list, silc_hash_table_get and the
1528 SilcHashTableList structure to provide an alternative way to
1529 traverse the hash table. The affected files are
1530 lib/silcutil/silchashtable.[ch].
1532 * Changed the server's idlist routines to use the hash table
1533 routines to optimize the code.
1535 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1537 * Replaced the client entry's `channel' list and channel entry's
1538 `user_list' list to hash tables for optimized lookup. Changed
1539 the code to use the hash table interface around the code.
1540 Affected file lib/silcd/idlist.[ch].
1542 * Added `auto_rehash' boolean argument to the function
1543 silc_hash_table_alloc to indicate whether the hash table should
1544 auto-rehash when it thinks is appropriate time. It will
1545 increase the hash table size if the there is twice as much
1546 entries in the table than the size of the table, and will
1547 decrease the size if there are twice as less entries than
1548 the size of the table.
1550 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1552 * Fixed silc_xxx_get_supported to not crash at some circumstances.
1554 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1556 * silc_idcache_purge_by_context deletes the entry now by context
1557 as it is supposed to do. Affected file lib/silccore/idcache.c.
1559 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
1560 client is not anymore valid (WHOWAS givens the info) and not
1561 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
1563 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1565 * Removed the `data' and `data_len' arguments from the ID Cache
1566 interfaces and added `name' argument. ID Cache does not handle
1567 anymore the binary data only a names associated with given ID.
1569 * When hashing a Client ID with silc_hash_id the entire ID is
1570 not hashed anymore, instead only the hash of the Client ID is
1571 hashed. This way we can access the Client ID from the cache
1572 with Client ID but with the hash of the ID (which is a hash of
1573 the nickname) as well without any difference in performance.
1575 Added also silc_idcache_find_by_id_one_ext to do one on one
1576 searching when we have the actual ID. Added also function
1577 silc_hash_client_id_compare. The affected files are
1578 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
1580 * When hashing the name associated with a ID it is always done
1581 in lowercase. This way we can access the cache without worrying
1582 about case-sensitivity, even though, for example nicknames are
1585 * Fixed a bug in server with channel message sending. It put
1586 wrong ID type as destination ID. The affected file
1587 silcd/packet_send.c.
1589 * silc_idcache_del_by_context now deletes from all hash tables
1590 by context. Affected file lib/silccore/idcache.c.
1592 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1594 * Changed the client library to use the new ID Cache interface.
1595 Changes around the source tree.
1597 * Added silc_hash_table_rehash_ext to rehash with specific
1598 hash function. Affected file lib/silcutil/silchashtable.[ch].
1600 * Added silc_hash_string_compare to compare two strings in the
1601 hash table. Affected file lib/silcutil/silcutil.[ch].
1603 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1605 * Added new function silc_idcache_del_by_context into the
1606 lib/silccore/idcache.[ch].
1608 * Changed the server's ID list routines to use the new ID Cache
1609 interface. Changes around the source tree.
1611 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1613 * Added silc_hash_table_del[_by_context]_ext functions in to the
1614 lib/silcutil/silchashtable.[ch].
1616 Removed silc_hash_table_find_all* routines and added new
1617 silc_hash_table_find_foreach to replace them.
1619 Added silc_hash_table_replace_ext function as extended
1620 replacing function. Separated the simple hash table interface
1621 from the extended hash table interface in the file
1622 lib/silcutil/silchashtable.h.
1624 * Fixed minor bugs and changed it to use some of the new
1625 hash table functions in lib/silccore/idcache.c
1627 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1629 * Added new function silc_hash_table_find_all to return all keys
1630 in the hash table by the specified key. As the hash table is
1631 collision resistant it also makes it possible to have several
1632 duplicate keys in the hash table. This function may be used to
1633 find all of the keys from the hash.
1635 Added user_context arguments to the SilcHashFunction,
1636 SilcHashCompare and SilcHashDestructor to deliver user specified
1639 Added new fuctions silc_hash_table_find[_all]_ext to do
1640 extended lookup with specified hash and compare functions and
1641 specified user contexts.
1643 Added new function silc_hash_table_add_ext to add the key
1644 with specified hash function and user context.
1646 Added new function silc_hash_table_foreach to traverse all
1647 entrys in the hash table. Added SilcHashForeach callback
1650 Added new function silc_hash_table_del_by_context to delete
1651 the entry only if the context associated with the key matches.
1653 Affected files are lib/silcutil/silchashtable.[ch].
1655 * Removed silc_hash_[server/client/channel]_id and added just
1656 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
1657 silc_hash_id_compare to compare two ID's using as the hash table
1658 comparison function. Added also silc_hash_data to hash
1659 binary data and silc_hash_data_compare to compare it.
1661 * Removed silc_idlist_find_client_by_hash as it is not needed
1662 anymore. Affected file silcd/idlist.[ch].
1664 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
1665 to use internally the SilcHashTable. The new ID Cache is a lot
1666 faster than the old one. Some of the ID Cache interface was also
1667 rewritten and obsolete and stupid functions were removed.
1669 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1671 * Added entry_count field to the SilcHashTable to keep the number
1672 of the entries in the table. Implemented the function
1673 silc_hash_table_rehash. Added new function
1674 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
1676 Fixed a minor bug in silc_hash_table_free.
1678 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
1679 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
1680 into the lib/silcutil/silcutil.[ch].
1682 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1684 * Implemented a collision resistant hash table into the
1685 lib/silcutil/silchashtable[ch]. See the header and the source
1686 for the SilcHashTable API.
1688 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1690 * Merged dotconf version 1.0.2 into lib/dotconf.
1692 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1694 * Do not compile anything in lib/silcsim/* if the SIM support
1695 is not enabled. The tree should now compile without problems
1698 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1700 * Compiled the SILC under cygwin. Compiled and tested briefly
1701 without problems. More tests needed. The SIMs didn't compile
1704 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
1706 * Fixed possible crash in silc_get_username in the
1707 lib/silcutil/silcutil.c.
1709 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1711 * Fixed a va_arg in silc/client_ops.c.
1713 * Oops, RC5 routines were named AES and caused some problems
1714 when not using SIM's. Affected file lib/silccrypt/rc5.c.
1716 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1718 * Added new SilcIDIP structure into the lib/silccore/id.h and
1719 replaced the old `ip' fields from all SILC ID's to that type.
1720 This is a step towards IPv6 support.
1722 The silc_id_get_len takes now the ID as an extra argument.
1723 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
1724 both IPv4 and IPv6 based ID's.
1726 The affected files are lib/silccore/id.[ch] and other files
1727 around the tree using these routines.
1729 * Removed the ID length arguments in server from various
1730 silc_server_send_notify_* routines -> they are not needed
1733 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1735 * Fixed memory leak in silc_encode_pem_file in the file
1736 lib/silcutil/silcutil.c.
1738 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1740 * Check minor version as well in the SKE. Affected files are
1741 silcd/protocol.c and lib/silcclient/protocol.c.
1743 * Added --identifier option to the server so that an identifier
1744 can be when creating the public key for the server. Affected
1745 file is silcd/silcd.c.
1747 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
1748 lib/silccrypt/silcpkcs.c.
1750 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1752 * Register default ciphers and stuff when using -C option with
1753 the server. Affected file sildc/silcd.c.
1755 * Put back the servers public key filename format, it is better
1756 than the new one. For now, the client keys are saved with the
1757 new filename format. The affected file silc/client_ops.c.
1759 * Implemented the Cipher API for the rest of the ciphers that
1760 did not implement it or implemented it the wrong way.
1762 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1764 * Register default ciphers and stuff when using the -S option
1765 in the client. Affected file silc/silc.c. Same also when
1766 creating new key pair with -C option.
1768 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1770 * Fixed the silc_verify_public_key client operation function to
1771 save the public keys differently. The fingerprint is now
1772 used as filename and not the hostname. This way also the
1773 client keys are saved uniquely and not with hostnames. The
1774 affected file is silc/client_ops.c.
1776 * Trimmed the silc_hash_fingerprint function to remove extra
1777 whitespaces from the end of the fingerprint. The affected
1778 file is lib/silccrypt/silchash.c.
1782 * Added silc_cipher_register_default function to register all
1783 default ciphers. It can be used when configuration files
1784 does not exist and the application does not want any specific
1785 ciphers in any specific order.
1787 The SilcDList is now used as silc_cipher_list dynamically
1788 allocated cipher list. Removed the static list all together
1789 and now all ciphers must be allocated to the dynamic list.
1790 The silc_cipher_alloc routine was changed to check only the
1793 All silc_cipher_* routines that used to return int returns
1796 The affected files lib/silccrypt/silccrypt.[ch].
1798 * The same thing was done to silc_hash_* as for silc_cipher_*
1799 routines. Affected files lib/silccrypt/silchash.[ch].
1801 * The same thing was done to silc_pkcs_* as for silc_cipher_*
1802 routines. Affected files lib/silccrypt/silcpkcs.[ch].
1803 Added also silc_pkcs_[un]register[_default] functions.
1804 Removed the data_context from the PKCS API.
1806 * Added silc_hmac_register_default function to register default
1807 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
1808 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
1809 to unregister all hmacs at once.
1811 * Register the default ciphers, hash functions, PKCSs and HMACs
1812 if client's configuration file does not exist. The affected
1815 * The client did not load the hash functions from the SIM
1816 modules at all. Added support for this. Affected file is
1817 silc/clientconfig.c.
1819 * When decoding public key with silc_pkcs_public_key_decode, check
1820 the supported algorithm only if PKCS are registered. Affected
1821 file lib/silccrypt/silcpkcs.c. The same was done with the
1822 silc_pkcs_private_key_decode.
1824 * Fixed the SILC List routines to keep the list always in order.
1825 It used to change the list's order when traversing the list but
1826 not it preserves the order. Affected file lib/trq/silclist.h.
1828 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1830 * Added the client library to use the SilcSocketConnection's
1831 reference counter (by silc_socket_dup) to prevent the bug that
1832 the socket object may be freed underneath async operation.
1834 * The name resolv library checking fixes in the configure.in.pre.
1837 * Created new version of the protocol drafts for future
1838 development. The -03 drafts are the ones that will be changed
1839 in the trunk now and the -02 will remain as they are.
1841 * Send list of CUMODE notifys to the router when announcing
1842 the channel users to the router. Affected file silcd/server.c.
1843 If the router receiving channel founder CUMODE for a channel
1844 that already has channel founder it will send CUMODE notify
1845 to the sender to remove the channel founder rights from the
1846 announced client. Affected file silcd/packet_receive.c.
1848 * The CUMODE notify may now use Server ID as well as the entity
1849 who changes the mode. Updated protocool specs.
1851 * Updated INSTALL and README files.
1853 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1855 * New web pages in the http://silc.pspt.fi. The pages was
1860 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1862 * Implemented the [DenyConnectin] config section in the server.
1863 Added silc_server_config_denied_conn to check whether incoming
1864 connection is denied. Affected file silcd/serverconfig.[ch].
1866 * Do not check the ports when checking the incoming configuration
1867 data if the port is 0, meaning any. Affected file is
1868 silcd/serverconfig.c.
1870 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1872 * Fixed buffer overflow in silc_string_compare in the file
1873 lib/silcutil/silcutil.c.
1875 * Fixed double free in silc_server_command_leave in the file
1878 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1880 * Fixed the version checking in the server. Affected file is
1883 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1885 * Fixed the configuration data fetching when accepting new
1886 connections in the server. Affected file silcd/server.c.
1888 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1890 * Added `sender_entry' argument to the function
1891 silc_server_packet_relay_to_channel so that we can check
1892 whether some destination actually belongs to the same route
1893 the sender belongs (ie, we must not resend the packet to the
1894 sender). Affected file silcd/packet_send.[ch].
1896 * Added `servername' field to the SilcClientEntry in the server
1897 to hold the name of the server where client is from. Affected
1898 file is silcd/idlist.h.
1900 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1902 * Moved the channel message encrypting in the router betwen
1903 router connections from silc_server_channel_message to the
1904 silc_server_packet_relay_to_channel since we want to check
1905 whether we have anybody channel before encrypting anything.
1906 Affected files silcd/packet_[receive/send].c.
1908 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1910 * Fixed the [AdminConnection] server config section to support
1911 multiple entries. Affected file silcd/serverconfig.c.
1913 * Added support into the server to check the validity of the
1914 incoming connection before executing any KE or authentication
1917 * The connection configuration is now saved to the KE and
1918 connection auth protocol contexts and not fetched anymore in
1919 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
1921 * The local hosts listenning address and port is also resolved
1922 now when starting the server. We want to have the socket object
1923 to include the real address and port for the listener. Added
1924 new function silc_net_check_local_by_sock into the files
1925 lib/silcutil/silcnet.[ch].
1927 * Fixed a broadcast bug in server -> do not broadcast if we
1930 * Fixed a routing bug. Do not route broadcast packets ever.
1931 Broadcast packets must be processed always and not routed since
1932 they may be destined to some other host than yourself and thus
1933 would get routed without no good reason. Affected file is
1936 * Added function silc_server_config_is_primary_route to check
1937 whether primary router connection has been configured (a router
1938 configuration that we are initiating). If there is not, we
1939 will assume that there is only two routers in the SILC network
1940 and we will use the incoming router connection as our primary
1941 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
1943 * Changed the order of the broadcasting. Broadcast _after_ the
1944 packet has been processed not before. Affected file is
1947 * Fixed a [ClientConnection] parsing bug. The port was never
1948 parsed correctly thus resulting to port 0. Affected file
1949 silcd/serverconfig.c.
1951 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
1952 argument and did not set the broadcast packet flag. Affected
1953 file silcd/packet_send.c. Fixed same bug in the function
1954 silc_server_send_notify as well.
1956 * If we receive NEW_ID packet for our own ID in the server, ignore
1959 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Removed the nickname from the Private Message Payload.
1964 Updated the code and the protocol specs.
1966 * Updated protocol specs for submitting to the IETF.
1968 * Tweaked the Random Number Generator a bit. Affected file
1969 lib/silccrypt/silcrng.c. Exported a new function
1970 silc_rng_[global]_add_noise which can be used to add more
1973 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1975 * Do not parse packets with different timeout when protocol
1976 is active -> may cause problem with rekey. Affected file
1979 * When server receives signoff notify it must not create
1980 new channel key if the client is on any channels since the
1981 sender of the signoff notify will create it.
1983 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1985 * Added printing of error messages during SKE protocol from the
1986 failure packet sent by server during SKE. Affected file
1989 * Removed the client's failure_callback handling with timeout
1990 and handle it immediately when received.
1992 * The SKE library returned wrong type in SUCCESS and FAILURE
1993 packets. They must be 32 bit MSB not 16 bit MSB.
1995 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1997 * Ok, rewrote the logic of the re-key and now it seems to work.
1998 I tested it on high traffic with frequent re-keys without
1999 problems. Added hmac_receive (and renamed hmac to hmac_send)
2000 in SilcClientConnection in lib/silcclient/client.h and
2001 in SilcIDListData in silcd/idlist.h. Also, removed the
2002 SilcPacketParserContext's cipher and hmac fields as they are
2003 not needed anymore and actually caused some problems when
2004 the ciphers and hmac's changed underneath the packet parser.
2006 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2008 * If re-key protocol is active then process the incoming packets
2009 synchronously since we must assure that icoming packets encrypted
2010 with the old key is processed before the new keys is set to
2011 use. This is true other packets than for REKEY packets.
2012 Affected file silcd/server.c. The same was done to client library
2013 as well, affected file lib/silcclient/client.c.
2015 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2017 * Fixed bug in client and server to accept the force send if
2018 the packet is send from silc_[server/client]_packet_process
2019 function. Otherwise the packets are never delivered, oops.
2021 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2023 * Disable force sending of packets when REKEY protocol is active.
2024 We must assure that no packet is sent directly when rekey is
2025 performed. All packets must be sent through packet queue.
2026 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
2027 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
2028 function is silc_[server/client]_packet_send_real to check
2031 * Replaced the SIM paths from example config files to
2032 /usr/local/modules. Also, make install creates now
2033 /usr/local/silc/logs directory to hold all the SILC server
2036 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Made the configure.in.pre work on Solaris. Patch by salo.
2040 * Made all ciphers compatible with non-x86 machines. Defined
2041 CBC mode macros into lib/silccrypt/ciphers_def.h.
2043 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2045 * Fixed the make install.
2047 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2049 * When MAC computation fails the silc_packet_decrypt returned 0
2050 even though it was supposed to return -1. Fixed this. The
2051 affected file is lib/silccore/silcpacket.c.
2053 * Do not replace the config files in /etc/silc (in make install)
2054 if they already exist. Affected file ./Makefile.am.
2056 * Do not send re-key packets immediately but through packet queue.
2057 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
2059 * Changed silc_net_check_host_by_sock to return FALSE if the
2060 IP/DNS could not be resolved. Though, it returns the IP address
2061 now even if it could not resolve it (but returns also FALSE).
2062 Affected file lib/silcutil/silcnet.[ch].
2064 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2066 * Added silc_pkcs_decode_identifier to decode the public key's
2067 identifier. Affected file lib/silccrypt/silpkcs.[ch].
2068 Added also silc_pkcs_free_identifier. Added also new context
2069 SilcPublicKeyIdentifier.
2071 * Added -S option to the silc client. It is used to dump the
2072 contents of the specified public key file.
2074 * Changed the PKCS api to return the public key length when
2075 setting the public key.
2077 * Fixed a fatal bug in the public and private key file loading.
2078 Affected file lib/silccrypt/silcpkcs.c.
2080 * Execute the packet parsing for client with zero (0) timeout
2081 if the protocol is active. Affected file silcd/server.c.
2083 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2085 * Made the key generation options to the silcd program. Added
2086 -C option, equivalent to client's option.
2088 * Added new [ServerKeys] config section to the server. It
2089 configures the server's public and private key.
2091 * Defined generic Public Key Payload into the protocol
2092 specification to send specific type of public keys and
2095 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
2096 public key or certificate.
2098 * Implemented the GETKEY command to the server and to the
2099 client library and on user interface.
2101 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2103 * Made preliminary `make install' work.
2105 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2107 * Added SilcServerRekey context into silcd/idlist.h.
2109 * Added the PFS support as defined in the specification to the
2110 SKE protocol. Affected files lib/silcske/*.c.
2112 * Added `ske_group' field to the SilcServerRekey context to hold
2113 the number of the SKE group that is used with PFS in re-key.
2114 Affected file silcd/idlist.h.
2116 * Added PFS re-key support to the server. Affected file is
2119 * Added silc_protocol_cancel to cancel execution of the next
2120 state of the protocol. Affected file is
2121 lib/silccore/silcprotocol.[ch].
2123 * Added the re-key support with and without PFS to the client
2124 library. Re-key is performed once in an hour, by default.
2126 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
2127 Added silc_client_rekey_callback and silc_client_rekey_final.
2128 Affected files are lib/silcclient/protocol.[ch] and
2129 lib/silcclient/client.[ch].
2131 * Removed the `hmac_key' and `hmac_key_len' fields from the
2132 SilcClientConnection structure; not needed. Affected file is
2133 lib/silcclient/client.h.
2137 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2139 * Do not ask whether user wants to use the negotiated private key
2140 for private messages, just use it. Affected file is
2141 silc/local_command.c.
2143 * Added `send_enc_key' and `enc_key_len' fields to the
2144 SilcIDListData structure since they are needed in the re-key
2145 phase. Affected file is silcd/idlist.[ch].
2147 * Implemented the simple re-key protocol into the server.
2148 Affected files silcd/server.c and silcd/protocol.[ch]. The
2149 re-key will be performed once in an hour, by default.
2151 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
2152 Added silc_server_rekey, silc_server_rekey_callback and
2153 silc_server_rekey_final.
2155 * Removed Tunneled flag from the protocol. Updated the code
2156 and the specifications.
2158 * Adde `pfs' field to the SilcIDListData to indicate whether
2159 the PFS is to be performed in the re-key. Affected file is
2162 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2164 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
2165 int64 of at least the xintXX size. If void * is less that 4
2166 bytes uint32 * will be used. Defined bool as boolean.
2168 * Changed _ALL_ unsigned long and unsigned int to uint32,
2169 unsgined short to uint16 in the source tree.
2171 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
2172 not handle clients that has entry->data.registered == FALSE.
2173 They are not in the network anymore. Affected file is
2176 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2178 * Implemented the sending of the SERVER_SIGNOFF notify in the
2179 server. Affected file is silcd/server.c.
2181 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
2182 Added also silc_notify_payload_encode_args into the
2183 lib/silccore/silcnotify.[ch].
2185 * Implemented ther SERVER_SIGNOFF notify handling in the server.
2186 Affected file silcd/packet_receive.c.
2188 * Implemented the SERVER_SIGNOFF notify handling in the client
2189 library. Affected file lib/silcclient/client_notify.c. Also,
2190 implemnted the printing of the SERVER_SIGNOFF info to the
2191 application. Affected file silc/client_ops.c.
2193 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
2194 if the deleting was successful. Affected file silcd/idlist.[ch].
2196 * Added support for public key authentication in the connection
2197 authentication protocol in the client library. Affected file
2198 lib/silcclient/protocol.c.
2200 * Changed the server's silc_idlist_get_clients_by_* interface
2201 to support already allocated array so that new entries may be
2202 added to pre-allocated array. Affected file silcd/idlist.[ch].
2203 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
2204 and command replies.
2206 * All command reply functions in the server now calls the
2207 pending command callback even if error occured. This way the
2208 error will be delivered to the client as well. Affected files
2209 silcd/command.c and silcd/command_reply.c.
2211 * Fixed INFO command to return local server's info if no server
2212 was provided. Affected file lib/silcclient/command.c.
2214 * Removed RESTART command for good. Updated the code and the
2217 * Rewrote parts of the task system. It is a bit simpler now.
2218 Removed unsued task priorities. The affected files are
2219 lib/silcutil/silctask.[ch].
2221 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2223 * Moved the USERS printing from the library to the application.
2224 Affected files lib/silcclient/command.c and silc/client_ops.c.
2226 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2230 * Added channel key re-key support. The re-key is perfomed
2231 only by the router and is done once in an hour. Added `rekey'
2232 field to the SilcChannelEntry in the server. Affected files
2233 silcd/server.c and silcd/idlist.h.
2235 * Added silc_task_unregister_by_context into the file
2236 lib/silcutil/silctask.[ch].
2238 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2240 * Added SILC_UMODE_GONE mode to indicate when the client is not
2241 present in the SILC network. Added also support to the local
2242 command AWAY that will set this mode. Added support of showing
2243 "xxx is gone" in WHOIS command. The USERS command shows the
2244 gone status as well.
2246 * Fixed setting server and router operator privileges in the
2247 server's UMODE command. Affected file silcd/command.c.
2249 * Merged the SKE KE1 and KE2 payloads into one payload. The
2250 new KE payload is equivalent to the old KE2 payload.
2252 Cleaned up the SKE Start Payload parsing. It now uses the
2253 simple buffer unformatting to do the parsing. A lot faster
2256 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
2257 to the SKE that is used to indicate whether both of the SKE
2258 parties should perform authentication. By default only the
2259 responder performs authentication. By setting this flag also
2260 the initiator must do authentication. By default it is unset
2261 since in normal SKE case, client to server connection, only
2262 the responder should do authentication. When doing SKE between
2263 two clients both should perform authentication. Updated the
2264 code and the protocol specs.
2266 * A little fix to IDENTIFY command in the server. Search the
2267 client first by hash not nickname. Affected file is
2270 * Fixed the silc_client_close_connection to support closing
2271 the client to client connections wihtout deleting too much
2272 data. Affected file lib/silcclient/client.c.
2274 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
2275 are received if protocol used to be active but is not anymore
2276 the application would crash due to NULL pointer dereference.
2277 Affected files silcd/server.c and lib/silcclient/client.c.
2279 * Added `hash' field to the SilcClientConnection to include
2280 the hash function negotiated in the SKE protocol.
2282 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
2283 to set the channel founder authentication data. A client can
2284 claim the founder rights later by providing the authentication
2285 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
2286 This way the channel founder can regain the channel founder
2287 privileges even it is left the channel. This works only on
2288 local server and the client must be connected to the same
2289 server to be able to regain the founder rights. Updated the
2290 protocol specs accordingly.
2292 Added support to the CMODE command in the client to set the
2293 founder auth data. Read the README to see how to set it.
2295 Added support to the CUMODE command to claim the founder
2296 rights. Read the README to see how to do it.
2298 Added support for the founder authentication to the Channel
2299 Entry in the server. Affected file silcd/idlist.h.
2301 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
2302 server's CMODE command. Affected file silcd/command.c.
2304 * Added the following new functions into lib/silccore/silcauth.[ch]:
2305 silc_auth_get_method and silc_auth_get_data.
2307 * The server now saves the remote hosts public key to the
2308 SilcIDListData pointer. Affected file silcd/protocol.c.
2310 * The normal server now does not remove the channel entry from
2311 the cache if the founder authentication data is set. It used
2312 to remove it if the founder was the last one on the channel on
2313 the server and left the channel. The auth data is saved and
2314 if the channel is re-joined later the old entry is used with
2315 the old auth data. Affected files silcd/command_reply.c and
2318 * Removed the `pkcs' field from the SilcIDListData structure
2319 in the server; it is not used. Affected file silcd/idlist.h.
2321 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2323 * Fixed packet processing on slow links. Partial packets were
2324 never re-processed because the incoming data buffer was cleared
2325 by the application. Application must not directly clear the
2326 sock->inbuf, the packet processing routines handle it. Fixed
2327 this in client library and in server.
2329 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2331 * Fixed the WHOIS and IDENTIFY send reply function to really
2332 check whether to send list or just one entry. Affected file
2335 * Cleaned up the LEAVE command's channel key distribution. The
2336 affected file silcd/command.c.
2338 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
2339 can enforce the channel mode as well. In that case the ID
2340 includes the ID of the server. The code now enforces the
2341 mode change if the router have different mode than the server.
2343 * The notify client operation with CMODE_CHANGE notify can now
2344 return NULL client_entry pointer if the CMODE was not changed
2345 by client. Application must check for this.
2347 * Added <Server ID> argument to INFO command to support server
2348 info fetching by Server ID.
2350 * Added silc_server_announce_get_channel_users to get assembled
2351 packets of channel users of the specified channel. Affected
2352 file silcd/server.[ch].
2354 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
2355 was freed underneath the ID Cache.
2357 * Re-announce clients when the server received CHANNEL_CHANGE
2358 notify from the router. Affected file silcd/packet_send.c.
2360 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2362 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
2363 crashed since it did not handle the fact that there is no cipher
2364 called "3" and didn't check the error condition. Now fixed.
2366 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
2367 flag. It can be used to send message requests.
2369 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2371 * Implemented the RESTART command in the client.
2373 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
2374 notice type messages. Added notice printing to the user
2377 * The channel keys are not re-generated if the channel's mode
2378 is PRIVKEY, ie private key on the channel exists. Affected
2379 files silcd/server.c and silcd/command.c.
2381 * Fixed a little bug in channel message delivery when channel
2382 private keys are set in the server. Affected file is
2383 silcd/packet_send.c.
2385 * Changed the setting on channel->on_channel = TRUE from the
2386 silc_client_save_channel_key to the JOIN command reply. The
2387 key payload is not received if the private channel key is set.
2388 Affected file lib/silcclient/command_reply.c and the
2389 lib/silcclient/client_channel.c.
2391 * When the CMODE_CHANGE notify is sent and the channel private
2392 key mode is removed the channel key must be re-generated in
2393 other cells as well. Added this support for the router in the
2394 silcd/packet_receive.c.
2396 * Added new local command NOTICE to send notice message on
2397 channel. Affected file silc/local_command.[ch].
2399 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2401 * Added new local command ME to the client. It is used to send
2402 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
2403 some action. Affected file silc/local_command.[ch].
2405 * Changed channel_message and private_message client operations
2406 to deliver the message flags to the application. Added also
2407 the `flags' arguments to the silc_client_send_channel_message
2408 and silc_client_send_private_message functions. Affected file
2411 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2413 * Redefined the Private Message Payload to support private message
2414 keys and to support the new private message flags. Updated
2415 the protocol specs. Flags makes it possible to have for example
2416 CTCP style messages.
2418 * Added new type SilcPrivateMessagePayload and defined an API
2419 for it in the lib/silcclient/silcprivate.[ch].
2421 * Tested private message private keys successfully. Tested the
2422 private message key set, unset and list commands with the new
2425 * Redefined the Channel Message Payload to include the channel
2426 message flags (equal with private message flags) to support
2427 for example CTCP style messages.
2429 * Defined some of the message (for channel and private message)
2430 flags. Updated the protocol specs and added the flags to the
2431 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
2433 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2435 * Added SilcKeyAgreementStatus type to the key agreement routines
2436 to indicate the current status and error if one occured.
2437 The status types are defined in the lib/silcclient/silcapi.h.
2439 * Added new local command KEY that is used to set and unset private
2440 keys for channels, set and unset private keys for private messages
2441 with remote clients and to send key agreement requests and
2442 negotiate the key agreement protocol with remote client. The
2443 key agreement is supported only to negotiate private message keys,
2444 it currently cannot be used to negotiate private keys for channels,
2445 as it is not convenient for that purpose.
2447 * Fixed a minor pending callback setting bug in the function
2448 silc_client_get_client_by_id_resolve, now the function works.
2449 Affected file lib/silcclient/idlist.c.
2451 * Added function silc_net_get_local_port to get local bound
2452 port by socket. Added to lib/silcutil/silcnet.[ch].
2454 * Added `sockets' and `sockets_count' fields to the SilcClient
2455 object. They hold the sockets of the listenning sockets in
2456 the client. Listenning sockets may be for example the key
2457 agreement server. Affected file lib/silcclient/client.[ch].
2458 Added functions the silc_client_add_socket and the
2459 silc_client_del_socket. They are exported to the application
2462 * Added ~./silc/clientkeys to support other client's public keys.
2464 * Renamed verify_server_key client operation to verify_public_key
2465 and added one argument to indicate the type of the connection
2466 (server, client etc.).
2468 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2470 * Added silc_server_connection_auth_request to handle the
2471 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
2472 silcd/packet_receive.[ch].
2474 * Added silc_server_send_connection_auth_request into the
2475 silcd/packet_send.c to send the connection auth request packet.
2477 * Cleaned up the silcd/protocol.c a bit and fixed some memory
2480 * Fixed the public key authentication in responder side in the
2481 server. The `auth_data' pointer includes the SilcPublicKey
2482 not the path to the public key. Affected file silcd/protocol.c.
2484 * Implemented the public key authentication in the initiator side
2485 in the server. Affected file silcd/protocol.c.
2487 * Removed the [RedirectClient] config section from the server
2488 configuration. Is not needed and I don't want to implement it.
2490 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2492 * Cleaned up the CMODE command in the server. It now works
2493 correctly and supports all the modes defined in the protocol.
2494 Affected file is silcd/command.c.
2496 * Added `hmac_name' field to the SilcChannelEntry in the server
2497 to hold the default HMAC of the channel. It can be set when
2498 creating the channel (with JOIN command). Affected files
2501 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
2502 type to indicate the change of the current cipher and hmac
2503 on the channel. Client can safely ignore the <cipher> argument
2504 (if it chooses to do so) since the CHANNEL_KEY packet will
2505 force the channel key change anyway. The <hmac> argument is
2506 important since the client is responsible of setting the new
2507 HMAC and the hmac key into use.
2509 * Fixed the CMODE command in the client library as well.
2511 * Tested CMODE command in router environment successfully.
2513 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2515 * Show the version of the remote client (or server) when connecting
2516 to the server. It is logged to the log file. Affected file
2517 is silcd/protocol.c.
2519 * Fixed the KILLED notify handling in the client library. The
2520 client must be removed from all channels when receiving the
2523 Also, do not remove the client entry when giving the KILL
2524 command but when the KILLED notify is received.
2526 * Removed silc_idlist_find_client_by_nickname from the server.
2527 Not needed anymore. Affected files silcd/idlist.[ch].
2529 * Implemented the CHANNEL_CHANGE notify type handling to the
2530 server. Affected file silcd/server.c.
2534 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2536 * Added silc_server_send_notify_invite to send the INVITE
2537 notify between routers.
2539 * Implemented the INVITE command correctly to the server.
2541 * Implemented the INVITE notify type handling in the server.
2543 * Implemented the INVITE command to the client library and on the
2546 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2548 * Added function silc_server_get_client_resolve to find the
2549 client entry by ID from all ID lists and then resolve it
2550 (using WHOIS) if it cannot be found. Affected file is
2553 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2555 * Implemented the BAN command to the client library.
2557 * The JOIN command in the server now checks the invite list
2560 * Changed the silc_command_reply_payload_encode_va and the
2561 silc_command_payload_encode_va to support that if argument is
2562 NULL it ignores and checks the next argument. Affected file
2563 lib/silccore/silccommand.c.
2565 * Added silc_server_send_notify_ban to send the BAN notify
2566 type between routers.
2568 * Chaned the silc_notify_payload_encode to support that if
2569 argument is NULL it ignores and checks the next argument.
2570 Affected file lib/silccore/silcnotify.c.
2572 * Tested ban lists in router environment successfully.
2574 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2576 * Implemented BAN command to the server, in silcd/command.[ch].
2578 * Removed the BAN and INVITE_LIST modes from the CMODE command
2581 * Added function silc_string_match to regex match two strings.
2582 Affected files lib/silcutil/silcutil.[ch].
2584 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2586 * Redefined parts of the SilcChannelEntry in the server to support
2587 the new ban and invite lists.
2589 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2591 * Redefined the INVITE command. The same command can be used to
2592 invite individuals to the channel but also to manage the invite
2593 list of the channel (to add to and remove from the invite list).
2594 Updated the protocol specs.
2596 * Added new command SILC_COMMAND_BAN that can be used to manage
2597 the ban list of the channel. Updated the protocol specs.
2599 * Removed the channel modes: the SILC_CMODE_BAN and the
2600 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
2601 in the CMODE command. The equivalent features are now available
2602 using INVITE and BAN commands. Updated the protocol specs.
2604 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
2605 in the network about change in the current ban list. The notify
2606 type is not used by the client.
2608 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
2609 support the invite lists.
2611 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2613 * Added new function silc_string_regexify that converts string
2614 including wildcard characters into regex string that can
2615 be used by the GNU regex library. Added into the file
2616 lib/silcutil/silcutil.[ch].
2618 Added silc_string_regex_combine to combine to regex strings
2619 into one so that they can be used as one regex string by
2620 the GNU regex library. Added into the file
2621 lib/silcutil/silcutil.[ch].
2623 Added silc_string_regex_match to match two strings. It returns
2624 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
2626 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2628 * Imported GNU regex to the soruce tree into lib/contrib.
2629 Fixed some compiler warning from the regex.c.
2631 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2633 * Fixed MOTD command in the server to work in router environment.
2635 * Fixed the MOTD command in the client library to support
2636 the server argument in the command.
2638 * Added `nickname_len' argument to the silc_idlist_add_client
2639 in the server, as the `nickname' argument may be binary data
2642 * Added silc_idlist_get_channels to return all channels from
2645 * Implemented LIST command to the server. Affected file is
2648 * Implemented the LIST command to the client library and on the
2651 * Added [<user count>] argument to the LIST command reply.
2652 With private channels the user count is not shown.
2654 * Updated TODO and README.
2656 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * The client entry's data.registered must be TRUE even with
2659 global client entry on global client list. The data.registered
2660 is used to check whether the client is anymore in the network,
2661 for example with WHOWAS command so it must be valid.
2663 * Fixed the WHOWAS command in the server. It now actually works
2664 in router environment. Added function into silcd/command_reply.c
2665 silc_server_command_reply_whowas_save.
2667 * Added silc_idlist_purge function to the silcd/idlist.c
2668 to periodically purge the ID Cache.
2670 * Fixed INFO command in the server. It works now in router
2671 environment. Added <server name> argument to the INFO command
2672 reply. Updated the protocol specs.
2674 * Fixed minor bug in silc_idcache_purge to not purge if the
2675 expire value is zero.
2677 * Fixed various bugs in WHOIS and IDENTIFY command handling as
2678 they were buggy because of the WHOWAS information.
2680 * Fixed local command MSG to handle the async resolving of
2681 the remote client properly. It used to fail the first MSG.
2682 Affected file silc/local_command.c.
2684 * Added `data_len' field to SilcIDCache context.
2686 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2688 * Update TODO. Todo in commands in the server.
2690 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2692 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
2693 used by routers as broadcast packet to inform other routers
2694 about the changed user mode.
2696 Implemented the notify handling in the server. Affected file is
2697 silcd/packet_receive.c. Added the function
2698 silc_server_send_notify_umode to the silcd/packet_send.[ch].
2700 * Added new generic Channel Payload and deprecated the New Channel
2701 Payload. The New Channel Payload is now the generic Channel
2704 * Added new argument `mode' to the silc_server_send_new_channel
2705 as it is required in the Channel Payload now.
2707 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
2708 and created a new and real SilChannelPayload to represent the
2709 new generic Channel Payload. Implemented the encode/decode
2710 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
2712 * Added silc_server_get_client_channel_list to return the list
2713 of channels the client has joined for WHOIS command reply.
2714 Affected file silcd/server.[ch].
2716 * Implemented the channel list sending in the WHOIS command reply
2717 in server and in the client.
2719 Implemented the channel list displaying on the user interface
2720 as well. Affected file silc/client_ops.c.
2722 * Added silc_channel_payload_parse_list to parse list of Channel
2723 Payloads. It returns SilcDList list of SilcChannelPayloads.
2724 Client for example can use this function to parse the list of
2725 channels it receives in the WHOIS command reply. The caller
2726 must free the list by calling silc_channel_payload_list_free.
2727 Affected files lib/silccore/silcchannel.[ch].
2729 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2731 * Added one new argument <user mode> to the WHOIS command reply
2732 to return the mode of the user in SILC. Updated the protocol
2735 Implemented it to the server and client.
2737 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2739 * Fixed the mode printing on the user interface on joining.
2740 Affected file silc/client_ops.c.
2742 * Implemented the UMODE command and user modes in general to the
2743 client library and to the user interface.
2745 * Implemented the UMODE command to the server.
2747 * The server now sends UNKNOWN_COMMAND error status if client sends
2748 unknown command. Affected file silcd/command.c.
2750 * All server commands now handle the command identifier the right
2751 way when sending the command reply to the client. The client can
2752 use to identify the command replies with the identifier.
2754 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2756 * Added silc_server_get_client_route to resolve the route to
2757 the client indicated by the client ID. Affected file is
2760 * Added silc_server_relay_packet as general function to relay
2761 packet to arbitrary destination. This deprecates functions
2762 like _send_private_message_key, _relay_notify etc. Affected
2763 file is silcd/packet_send.[ch].
2765 Removed silc_server_send_key_agreement,
2766 silc_server_send_private_message_key and
2767 silc_server_packet_relay_notify functions from the file
2768 silcd/packet_send.[ch].
2772 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
2773 server. Affected file silcd/packet_receive.[ch].
2775 * Implemented the KILL command to the client. Implemented the
2776 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
2777 Affected files lib/silcclient/command[_reply].c and
2778 lib/silcclient/client_notify.c. Implemented the KILL notify
2779 printing in the user inteface.
2781 * Fixed a lot silc_parse_nick memory leaks from the client
2782 library in the file lib/silcclient/command.c.
2784 * Changed the silc_server_send_notify_on_channels's `sender'
2785 argument from SilcSocketConnection to SilcClientEntry to
2786 check the sender as entry and not as connection object and not
2787 to send to the client provided as argument. The affected file
2788 is silcd/packet_send.[ch].
2790 * The notify packets that are destined directly to the client used
2791 to not to be processed by the server. Now changed that and the
2792 server processes all notify packets. After relaying the packet
2793 to the client the notify packet is processed in the server.
2795 * The silc_server_free_client_data now checks whether there is
2796 pending outgoing traffic for the client and purges the data to
2797 the network before removing the client entry.
2799 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
2802 an client is killed from the SILC Network. Updated the protocol
2805 Added new function silc_server_send_notify_killed to the
2806 silcd/packet_send.[ch].
2808 * Added function silc_server_packet_relay_notify to relay notify
2809 packets that are destined directly to a client. In this case
2810 the server does not process the notify packets but merely relays
2811 it to the client. Affected file silcd/packet_send.[ch].
2813 Added also silc_server_packet_process_relay_notify to check
2814 whereto relay the notify. Affected file is
2815 silcd/packet_receive.[ch].
2817 * Implemented the KILL command to the server.
2821 * Added the backup schema desgined last fall to the protocol
2822 specs for everyone to see. The specification is in the
2823 *-spec-xx.txt draft and the packet type definitions for the
2824 backup routers is in *-pp-xx.txt draft. Thusly, added also
2825 new packet type SILC_PACKET_CELL_ROUTERS.
2827 * A big security problem in the implementation discovered. The
2828 signoff of an client did not cause new channel key generation
2829 which it of course should've done. The channel keys must be
2830 always re-generated when client leaves (or signoffs) the channel.
2831 The silc_server_remove_from_channels funtion now handles
2832 the channel key re-generation.
2834 * Added `sender' argument to the silc_server_send_notify_on_channels
2835 to not to send the client provided as argument. Affected file
2836 silcd/packet_send.[ch].
2838 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2840 * Implemented OPER and SILCOPER commands into the server and
2843 * Added silc_auth_verify and silc_auth_verify_data to verify
2844 the authentication directly from the authentication payload.
2845 It supports verifying both passphrase and public key based
2846 authentication. Affected file lib/silccore/silcauth.[ch].
2848 * Added `hash' field to the SilcIDListData structure. It is the
2849 hash negotiated in the SKE protocol. Affected file is
2852 * Slight redesigning of the SilcAuthPayload handling routines.
2853 Do not send SilcPKCS but SilcPublicKey as argument.
2855 * Implemented the public key authentication support to the
2856 serverconfig. The public key is loaded from the provided path
2857 and saved as authentication data to void * pointer. Thus,
2858 changed the unsigned char *auth_data to void *auth_data;
2860 * Fixed SHUTDOWN command to send the reply before the server
2861 is shutdown. :) Affected file silcd/command.c.
2863 * Fixed fatal bug in CONNECT command. The hostname was invalid
2864 memory and server crashed. Affected file silcd/command.c.
2866 * Fixed fatal bug in CLOSE command. The server_entry became
2867 invalid but was referenced later in the command. Affected file
2870 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2872 * Fixed fatal bug in failure packet handling. Server ignored
2873 the failure and thus crashed when it came.
2877 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2879 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
2880 that the command may be executed only once in (about) 2 seconds.
2881 The old SILC_CF_LAG flag is same but allows command bursts up
2882 to five before limiting.
2884 Added the support for CF_LAG and CF_LAG_STRICT flags to the
2885 server code. Various commands now includes the CF_LAG_STRICT
2886 flag to disallow any kind of miss-use of the command.
2888 * Fixed the silc_buffer_unformat to not to allocate any data
2889 if the length of the data is zero. It used to allocate the
2890 length + 1. Affected file lib/silcutil/silcbuffmt.c.
2892 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2894 * Changed the format of AdminConnection configuration section
2895 in the server. Added username of the admin to the format.
2896 Affected files silcd/serverconfig.[ch].
2898 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
2899 to return admin configuration data by host, username and/or
2902 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2904 * Implemented WHOWAS command to the server. Added the functions:
2906 silc_server_command_whowas_parse,
2907 silc_server_command_whowas_send_reply,
2908 silc_server_command_whowas_from_client and
2909 silc_server_command_whowas_from_server
2911 * Added <Client ID> argument to the WHOWAS command reply. Updated
2912 the protocol specs accordingly.
2914 * Implemented WHOWAS command and command_reply to the client
2917 Implemented the WHOWAS printing on the user interface.
2919 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2921 * Added new argument to the WHOWAS command reply, the real name.
2922 It is an optional argument. Updated the protocol specs.
2924 * Added SilcIDCacheDestructor callback that is registered when
2925 the SilcIDCache is allocated. The callback is called when
2926 an cache entry in the ID Cache expires, or is purged from the
2927 cache. Added into lib/silccore/idcache.[ch].
2929 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
2930 to destruct the client entries when the cache entry expires.
2931 Other ID Cache's in server and in the client library ignores
2934 * If the ID Cache entry's `expire' field is zero then the entry
2935 never expires. Added boolean `expire' argument to the
2936 silc_idcache_add function in the lib/silccore/idcache.[ch].
2937 If it is TRUE the default expiry value is used.
2939 * Added silc_server_free_client_data_timeout that is registered
2940 when client disconnects. By default for 5 minutes we preserve
2941 the client entry for history - for WHOWAS command.
2943 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2945 * Added support to the server to enforce that commands are not
2946 executed more than once in 2 seconds. If server receives
2947 commands from client more frequently, timeout is registered
2948 to process the commands. Affected file silcd/command.c.
2949 Added new function silc_server_command_process_timeout.
2951 * Changed NICK_NOTIFY handling in client library to check that
2952 if the client's nickname was changed, so there is no need to
2953 resolve anything from the server.
2955 * Removed error printing from the WHOIS and IDENTIFY commands.
2956 If error occurs then it is ignored silently in the client library.
2957 The application, however, may map the received error to
2958 human readable error string. The application currently maps
2959 the NO_SUCH_NICKNAME error to string.
2961 * Made the command status message public to the application. Moved
2962 them from lib/silcclient/command_reply.c to
2963 lib/silcclient/command_reply.h. The application can map the
2964 received command status to the string with the
2965 silc_client_command_status_message function.
2967 * Added check to the server to check that client's ID is same
2968 as the Source ID in the packet the client sent. They must
2971 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2973 * Added dist-bzip hook to the Makefile.am to make bzip2
2974 compressed distributions.
2976 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2978 * Server now enforces the maximum length for the nickname and
2979 the channel as protocol specification dictates. 128 bytes for
2980 nickname and 256 bytes for channel name.
2982 * Moved the WHOIS printing to the application. The client libary
2983 does not print out the WHOIS information anymore, the application
2984 must do it. Renamed silc_client_command_reply_whois_print to
2985 the silc_client_command_reply_whois_save.
2987 The client's idle time is also sent to the application now, and
2988 the idle is shown on screen.
2990 * Added silc_client_command_reply_identify_save to save the
2991 received IDENTIFY entries.
2993 * Do not check for channel private keys in message sending and
2994 reception if the channel does not have the PRIVKEY mode set.
2995 Affected file lib/silclient/client_channel.c.
2997 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2999 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
3000 just surfaced after chaning the JOIN procedure.
3002 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3004 * Added silc_client_get_clients_by_list to get client entries
3005 from Client ID list, that is returned for example by JOIN
3006 and USERS command replies. The application should use this
3007 function for example when JOIN command reply is received to
3008 resolve the clients already on the channel (library does not
3009 do that anymore as USERS command reply is not used in the JOIN
3010 procedure anymore). Affected files lib/silcclient/silcapi.h and
3011 lib/silcclient/idlist.c.
3013 * JOIN command reply and USERS command reply returns now SilcBuffer
3014 pointers instead of unsigned char pointers when returning
3015 the client list and mode list.
3017 * Added <Client ID> argument to the JOIN command reply, mainly
3018 for the server to identify for which client the command was
3019 originally sent. Updated protocol specs accordingly.
3021 * Added SilcDlist private_key pointer to the SilcChannelEntry
3022 in the client to support the channel private keys. Affected
3023 file is lib/silcclient/idlist.h.
3025 * Added SilcChannelPrivateKey argument to the function
3026 silc_client_send_channel_message so that application can choose
3027 to use specific private ke if it wants to. If it is not provided,
3028 the normal channel key is used, unless private keys are set.
3029 In this case the first (key that was added first) is used
3030 as the encryption key.
3032 * Implemented the support for channel private key handling.
3033 Implemented the following functions:
3035 silc_client_add_channel_private_key,
3036 silc_client_del_channel_private_keys,
3037 silc_client_del_channel_private_key,
3038 silc_client_list_channel_private_keys and
3039 silc_client_free_channel_private_keys
3041 Affected file lib/silcclient/client_channel.c.
3043 * Added the support for the private keys in the channel message
3044 sending and encryption and in the message reception and
3045 decryption. Affected funtions are
3046 silc_client_send_channel_message and silc_client_channel_message.
3048 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3050 * Added SKE's key verify callback to the client library's
3051 KE protocol context. Affected files lib/silcclient/protocol.[ch].
3053 * Removed the statement that server (or router) must send USERS
3054 command reply when joining to the channel so that the client
3055 knows who are on the channel. Instead, the client list and
3056 client's mode list is now sent in the JOIN command reply to the
3057 client who joined channel. This is better solution.
3059 * Added function silc_server_get_users_on_channel and function
3060 silc_server_save_users_on_channel to the silcd/server.[ch].
3062 * Removed function silc_server_command_send_users from the
3065 * Do not show topic on the client library anymore. The topic is
3066 sent in the command reply notify to the application and the
3067 application must show the topic now.
3069 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3071 * Added client searching by nickname hash into the IDENTIFY and
3072 WHOIS commands in the server as they were clearly missing from
3073 them. Affected file is silcd/command.c.
3075 * Fixed a bug in private message receiving in the client library.
3076 The remote ID was freed and it wasn't supposed, now it is
3079 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3081 * Minor fix to the channel payload; allocate the data area, as it
3082 needs to be of specific length.
3084 * If the key agreement port is zero then the operating
3085 system will define the bound port. Affected files are
3086 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
3088 * Added new function silc_channel_payload_decrypt into the file
3089 lib/silccore/silcchannel.[ch].
3091 * Moved the channel message etc, check from silc_packet_decrypt
3092 to applications. The library calls now a generic
3093 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
3094 when the packet is either normal or special. This was done to
3095 allow more wide range of checking that was not allowed when
3096 the code was in library. Now applications can do virtually any
3097 checks to the packet and return to the library the decision how
3098 the packet should be processed. Affected files are
3099 lib/silccore/silcpacket.[ch].
3101 Added silc_server_packet_decrypt_check to the server and
3102 silc_client_packet_decrypt_check to the client library.
3104 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
3105 to send with specified source and destination information.
3107 * Channel message delivery between routers was broken after the
3108 channel key distribution was fixed earlier. The channel key
3109 was used be to distributed to other routers as well which is not
3110 allowed by the protocol. Now this is fixed and channel keys
3111 really are cell specific and the channel message delivery between
3112 routers comply with the protocol specification.
3114 * Fixed various commands in server to check also the global list
3115 for the channel entry and not just the local list. The affected
3116 file silcd/command.c.
3118 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Added assert()s to buffer formatting and unformatting routines
3121 to assert (if --enable-debug) when error occurs. Affected
3122 file: lib/silcutil/silcbuffmt.c.
3124 * Changed to auto-reconnect to check whether the remote host is
3125 router and register the re-connect timeout if it is. It used
3126 to check that whether we are normal server, but router must do
3127 auto-reconnect with another router as well. Affected file
3130 * Removed the [<key len>] option from CMODE command as the cipher
3131 name decides the key length, nowadays. See the defined ciphers
3132 from the protocol specification.
3134 * Added [<hmac>] option to the CMODE command to define the HMAC
3135 for the channel. Added SILC_CMODE_HMAC channel mode.
3137 * Added [<hmac>] option for the JOIN command so that user can
3138 select which HMAC is used to compute the MACs of the channel
3141 * Added Hmac field to the Channel Message Payload. The integrity
3142 of plaintext channel messages are now protected by computing
3143 MAC of the message and attaching the MAC to the payload. The
3144 MAC is encrypted. Now, it is clear that this causes some
3145 overhead to the size of the packet but rationale for this is that
3146 now the receiver can verify whether the channel message decrypted
3147 correctly and also when private keys are set for the channel the
3148 receiver can decrypt the packet with several keys and check from
3149 the MAC which key decrypted the message correctly.
3151 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
3152 lib/silccrypt/silccipher.[ch].
3154 * Added silc_hash_len to return the digest length into the
3155 lib/silcrypt/silchash.[ch].
3157 * Rewrote parts of Silc Channel Payload interface in the
3158 lib/silccore/silcchannel.[ch]. The encode function now also
3159 encrypts the packet and parse function decrypts it.
3161 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * Fixed a minor formatting bug in the SKE's key material processing.
3164 It actually might have processed the keys wrong way resulting
3167 * Redefined the mandatory HMAC algorithms and added new algorithms.
3168 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
3169 and hmac-md5 truncated to 96 bits. The mandatory is now
3170 hmac-sha1-96. Rest are optional (including the one that used
3171 to be mandatory). Rationale for this is that the truncated HMAC
3172 length is sufficient from security point of view and can actually
3173 make the attack against the HMAC harder. Also, the truncated
3174 HMAC causes less overhead to the packets. See the RFC2104 for
3177 * Added new [hmac] configuration section. The SKE used to use
3178 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
3179 is of course wrong. The official names that must be proposed in
3180 the SKE are the ones defined in the protocol specification
3181 (hmac-sha1-96 for example). The user can configure any hmac
3182 using any hash function configured in the [hash] section. At
3183 least, the mandatory must be configured.
3185 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
3187 * Added HMAC list to the SKE proposal list. It has now both
3188 hash algorithm list and HMAC list. This makes the protocol
3189 incompatible with previous versions. The SKE now seems to work
3190 the way it is supposed to work, for the first time actually.
3192 * Defined plain Hash algorithms to the protocol specification.
3195 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3197 * Implemented support for key agreement packets into the server.
3198 Added functions silc_server_key_agreement and
3199 silc_server_send_key_agreement. Other than these functions,
3200 server has nothing to do with this packet.
3202 * Added support for private message key packets into the server.
3203 Added functions silc_server_private_message_key and
3204 silc_server_send_private_message_key.
3208 * Changed the silc_[client|server]_protocol_ke_set_keys to be
3209 called in the protocol's final callback instead in the END
3210 protocol state. This makes a little more sense and in the same
3211 time in client we can use the same protocol routines for normal
3212 key exchange and to key agreement packet handling as well.
3214 * Added to both client's and server's KE protocol context the
3215 SilcSKEKeyMaterial pointer to save the key material. We will
3216 bring the key material to the protocol's final callback by doing
3217 this. The final callback must free the key material.
3219 * Added SKE's packet_send callback into client's KE protocol
3220 context so that the caller can choose what packet sending function
3221 is used. This way we can use different packet sending when
3222 doing normal SKE when doing key agreement packet handling (in
3223 the key agreement packet handling we do not want to encrypt
3226 * Implemented the responder side of the key agreement routines
3227 in the client. The client can now bind to specified port and
3228 accept incoming key negotiation. The key material is passed
3229 to the application after the protocol is over.
3231 * Implemented the processing of incoming Key Agreement packet
3232 in the client. Added function silc_client_key_agreement to
3235 * Implemented the intiator side of the key agreement routines
3236 in the client. The client can now initiate key agreement with
3237 another remote client. The key material is passed to the
3238 application after the protocol is over.
3240 * Created client_keyagr.c to include all the key agreement
3243 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
3244 SILC_TASK_CALLBACK except that it is not static.
3246 * Created client_notify.c and moved the Notify packet handling
3247 from the client.[ch] into that file.
3249 * Created client_prvmsg.c and moved all private message and
3250 private message key routines from the client.[ch] into that file.
3252 * Create client_channel.c and moved all channel message and
3253 channel private key routines from the client.[ch] into that file.
3255 * Changed silc_client_get_client_by_id_resolve to resolve with
3256 WHOIS command instead of IDENTIFY command, in the file
3257 lib/silclient/idlist.c.
3259 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3261 * Implemented the SKE's responder side to the Client library.
3263 * When FAILURE is received to the protocol do not trust it
3264 blindly. Register a timeout to wait whether the remote closes
3265 the connection as it should do it, only after that process the
3266 actual failure. This was changed to both client and server.
3268 * Added client_internal.h to include some of the structures
3269 there instead of client.h in lib/silcclient/.
3271 * Added function silc_task_unregister_by_callback to unregister
3272 timeouts by the callback function.
3274 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3276 * Some "Incomplete WHOIS info" errors has been appearing on the
3277 log files. Took away the entry->userinfo check from WHOIS
3278 reply sending. The entry->userinfo is now " " if client did not
3279 provide one. I thought this was fixed earlier but something
3280 is wrong still. Let's see if the error still appears.
3282 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * Fixed a minor bug in the login when the channel key is
3285 re-generated in the server. It used to generate the key in
3286 wrong order and thus caused problems in the channel traffic.
3288 * Fixed a minor bug in channel key distsribution after
3289 KICK command. The key was not sent to the router even though
3292 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3294 * Added silc_ske_process_key_material_data as generic routine
3295 to process any key material as the SILC protocol dictates. The
3296 function is used by the actual SKE library but can be used by
3297 applications as well. This relates to the private message keys
3298 and the channel private keys since they must be processed the
3299 same way the normal SILC session keys. The protocol dictates
3300 this. Affected files: lib/silcske/silcske.[ch].
3302 Added also silc_ske_free_key_material to free the
3303 SilcSKEKeyMaterial structure.
3305 * Defined silc_cipher_set_key function to set the key for
3306 cipher without using the object's method function. The affected
3307 files: lib/silccrypt/silccipher.[ch].
3309 * Implemented silc silc_client_add_private_message_key,
3310 silc_client_add_private_message_key_ske,
3311 silc_client_del_private_message_key,
3312 silc_client_list_private_message_keys and
3313 silc_client_free_private_message_keys functions in the
3316 Added functions silc_client_send_private_message_key to send
3317 the Private Message Key payload and silc_client_private_message_key
3318 to handle incoming Private Message Key payload.
3320 * Added Cipher field to the Private Message Key payload to set
3321 the cipher to be used. If ignored, the default cipher defined
3322 in the SILC protocol (aes-256-cbc) is used.
3324 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3326 * Removed lib/silcclient/ops.h file.
3328 Redefined parts of the SILC Client Library API. Created new
3329 file silcapi.h that deprecates the ops.h file and defines the
3330 published Client Library API. Defined also private message key
3331 API and channel private key API into the file.
3333 This is the file that the application must include from the
3334 SILC Client Library. Other files need not be included by
3335 the application anymore.
3337 * Added new key_agreement client operation callback and also
3338 defined the Key Agreement library API for the application.
3340 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
3343 is used by clients to request key negotiation between another
3344 client in the SILC network. If the negotiation is started it
3345 is performed using the SKE protocol. The result of the
3346 negotiation, the secret key material, can be used for example
3347 as private message key.
3349 Implemented the Key Agreement payload into the files
3350 lib/silccore/silauth.[ch].
3352 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3354 * Redefined ciphers for the SILC protocol. Added some new ciphers
3355 and defined the key lengths for the algorithms. Changed the
3356 code accordingly. The default key length is now 256 bits.
3358 * Fixed SKE key distribution function silc_ske_process_key_material
3359 when the key length is more than 128 bits. The default key
3360 length in SILC is now 256 bits.
3362 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
3363 to indicate unsupported algorithm.
3365 * Renamed rijndael.c to aes.c and all functions as well.
3367 * Fixed a long standing channel key setting bug in client library.
3368 Weird that it has never surfaced before.
3370 * Fixed bug in channel deletion. If the entire channel is removed
3371 then it must also delete the references of the channel entry
3372 from the client's channel list as the client's channel entry and
3373 the channel's client entry share same memory.
3375 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3377 * Implemented CONNECT and SHUTDOWN commands in the client.
3379 * Implemented CLOSE command to the client.
3381 * Added the function silc_idlist_find_server_by_name into the
3382 files silcd/idlist.[ch].
3384 Added the function silc_idlist_find_server_by_conn into the
3385 files silcd/idlist.[ch].
3387 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3389 * DIE command was renamed to SHUTDOWN. Updated the both code
3392 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
3393 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
3395 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
3398 * Added function silc_server_create_connection function to create
3399 connection to remote router. My server implementation actually
3400 does not allow router to connect to normal server (it expects
3401 that normal server always initiates the connection to the router)
3402 so the CONNECT command is only good for connecting to another
3405 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3407 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
3408 or some other client was kicked from the channel.
3410 Implemented the handling of the notify type to both client
3413 Implemented silc_server_send_notify_kicked to send the KICKED
3414 notify. It is used to send it to the server's primary router.
3416 * Implemented the KICK command into server and client.
3418 * Added `query' argument to the silc_idlist_get_client function
3419 to indicate whether to query the client from server or not if
3422 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
3423 to indicate that the client is not channel founder.
3427 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3429 * Removed the rng context from SilcPacketContext structure and
3430 changed that the packet routine uses the Global RNG API.
3432 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3434 * Added support for quit message that client can "leave" on the
3435 channel when it quits the SILC. It is ditributed inside the
3436 SILC_NOTIFY_TYPE_SIGNOFF notify type.
3438 Added silc_server_free_client_data that will take the
3439 signoff message as argument.
3441 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
3443 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3445 * Updated parts of the protocol specification to keep it up
3448 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3450 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
3451 payloads in one packet.
3453 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
3454 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
3455 use now the new List flag.
3457 * Also deprecated the following packet types: REPLACE_ID,
3458 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
3460 * Added list support for Notify packet in server.
3462 * Added silc_server_send_notify_channel_change to send the
3463 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
3464 the silc_server_send_replace_id.
3466 * Added silc_server_send_notify_nick_change to send the
3467 NICK_CHANGE notify type. Deprecates the function
3468 silc_server_send_replace_id.
3470 * Added silc_server_send_notify_join to send the JOIN notify type.
3471 Deprecates the function silc_server_send_new_channel_user.
3473 * Added silc_server_send_notify_leave to send LEAVE notify type.
3474 Deprecates the function silc_server_send_remove_channel_user.
3476 * Added silc_server_send_notify_cmode and
3477 silc_server_send_notify_cumode to send CMODE and CUMODE notify
3478 types. Deprecates the silc_server_send_set_mode function.
3480 * Added SERVER_SIGNOFF notify type to indicate that server has
3481 quit. This means that all clients on the channel from that
3482 server will drop. This can be also used when netsplit happens.
3484 Deprecated REMOVE_ID packet type since it is not needed anymore
3487 Added silc_server_send_notify_server_signoff to send the
3488 SERVER_SIGNOFF notify type. Deprecates the function
3489 silc_server_send_remove_id.
3491 Added also silc_server_send_notify_signoff to send the
3492 SIGNOFF notify type.
3494 * Employed the PKCS #1. It is the mandatory way to do RSA in the
3495 SILC protocol from this day on. Changed the protocol
3496 specification as well.
3498 * Added silc_server_send_notify_topic_set to send TOPIC_SET
3499 notify type. It is used between routers to notify about
3500 topic changes on a channel.
3502 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
3505 * Partly updated the protocol specification to comply with the
3506 changes now made. It is still though a bit outdated.
3508 * The JOIN notify type now takes one extra argument <Channel ID>.
3509 The packet used to be destined to the channel but now the
3510 JOIN type may be sent as list thus it is impossible to
3511 destine it to any specific channel. By adding this argument
3512 it is again possible.
3514 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3516 * Added CREDITS file. The CHANGES and CREDITS file will appear
3517 in the distribution as well.
3519 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
3522 types in the server's silcd/packet_receive.c.
3524 * Implemented CMODE and CUMODE to work in router environment.
3526 * Fixed minor encoding and decoding buglet from the
3527 lib/silccore/silcmode.c.
3529 * Fixed buffer overflow from lib/silcclient/command.c in USERS
3532 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
3534 * Changed all SilcConfigServer* and silc_config_server* to
3535 SilcServerConfig* and silc_server_config*, respectively.
3538 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3540 * Associated the ID (client or server ID) to the Authentication
3541 Payload to avoid any possibility of forging. Updated the
3542 protocol specification and the code accordingly.
3544 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3546 * The RSA key length is now save to the RsaKey context in the
3547 key generation process in lib/silccrypt/rsa.c. The key length
3548 is now used to figure out the maximum size of the block allowed
3549 to be encrypted/signed.
3551 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
3552 is equivalent to the silc_mp_mp2bin but does not allocate any
3555 * Changed silc_mp_mp2bin API to take length argument. If it is
3556 non-zero then the buffer is allocated that large. If zero, then
3557 the size is approximated using silc_mp_sizeinbase, which however
3560 * Created Global RNG API which is global RNG that application can
3561 initialize. After initializing, any routine anywhere in the
3562 code (including library) can use RNG without allocating a new
3563 RNG object. This was done to allow this sort of use of the
3564 RNG in code that has no chance to allocate RNG object. All
3565 applications currently allocate this and many routines in the
3566 library use this. Affected file lib/silccrypt/silcrng.[ch].
3568 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
3569 it to use the Global RNG API.
3571 * Defined Authentication Payload into protocol specification that
3572 is used during SILC session to authenticate entities. It is
3573 used for example by client to authenticate itself to the server
3574 to obtain server operator privileges.
3576 Implemented this payload into the lib/silccore/silcauth.[ch].
3577 Implemented also routines for public key based authentication
3578 as the new protocol specification dictates.
3580 Moved definitions of different authentication methods from
3581 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
3583 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
3584 silc_pkcs_verify and silc_pkcs_sign_with_hash and
3585 silc_pkcs_verify_with_hash functions into the file
3586 lib/silccrypt/silcpkcs.[ch].
3588 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3590 * The client entry's userinfo pointer must be always valid.
3591 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
3592 will fail since it requires the userinfo. Now, the userinfo
3593 is allocated as "" if actual userinfo does not exist. Actually,
3594 it must exist and it is totally Ok to drop client connections
3595 that does not announce the userinfo. However, we will make
3596 this workaround for now.
3598 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
3599 to return the remote port by socket.
3601 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3603 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
3604 SILC_SERVER_PENDING_EXEC and added an new macro
3605 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
3606 data or when error occurs while processing the pending command.
3608 Added new argument `destructor' into silc_server_command_pending
3609 and to the SilcServerCommandPending object. This destructor is
3610 now called after calling the pending callback or if error occurs
3611 immediately. If error occurs the actual pending callback won't
3612 be called at all - only the destructor. The destructor may be
3613 NULL if destructor is not needed.
3615 All this applies for client library code as well. Similar
3616 changes were made there as well for the pending commands.
3618 In the client, the application must now allocate the
3619 SilcClientCommandContext with the silc_client_command_alloc
3622 * Added reference counter to the SilcServerCommandContext. Added
3623 function silc_server_command_alloc and silc_server_command_dup
3626 Same type of functions added to the client library for the same
3629 * Removed the cmd_ident from IDListData away since it is now
3630 global for all connections. It is the command identifier used
3631 in command sending and with pending commands. The affected file
3634 * Added reference counter to the SilcSocketConnection objecet to
3635 indicate the usage count of the object. The object won't be
3636 freed untill the reference counter hits zero. Currently only
3637 server uses this, and client ignores it. The client must be
3638 set to use this too later. The affected files are
3639 lib/silccore/silcsockconn.[ch]. Added also the function
3640 silc_socket_dup to increase the reference counter.
3642 This was mainly added because it is possible that the socket
3643 is removed underneath of pending command or other async
3644 operation. Now it won't be free'd and proper DISCONNECTING
3645 flags, etc. can be set to avoid sending data to connection that
3646 is not valid anymore.
3648 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
3649 the connection. After that it sets SILC_SET_DISCONNECTED.
3650 It is, however, possible that the socket data is not still freed.
3651 The silc_server_packet_process now checks that data is not
3652 read or written to connection that is DISCONNECTED. The socket
3653 get's freed when the reference counter hits zero.
3655 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3657 * Changed the client operation API: channel_message operation's
3658 `sender' is now the client entry of the sender, not the nickname
3659 and the `channel' is the channel entry, not the channel name.
3661 In the private_message operation the `sender' is now also the
3662 client entry of the sender not the nickname.
3664 Affected file is lib/silcclient/ops.h and all applications
3665 using the client operations.
3667 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3669 * Moved the calling of ops->connect() from connect_to_server_final
3670 into receive_new_id functin since that is the point when the
3671 client is actually allowed to send traffic to network. The
3672 affected file is lib/silcclient/client.c.
3674 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
3677 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
3678 (if needs broadcasting) instead of broadcasting the packets one
3679 by one which would make a burst in the network traffic.
3681 * Added `broadcast' argument to the functions in silcd/server.[ch]
3682 silc_server_create_new_channel[_with_id] to indicate whether
3683 to send New Channel packet to primary router.
3685 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3687 * Added new function into the silcd/server.[ch] files:
3688 silc_server_create_new_channel_with_id to create new channel with
3689 already existing Channel ID.
3691 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
3692 lib/silccore/silcpacket.h. This packet is used t send list of
3693 Set Mode payloads inside one packet. Server uses this to set
3694 the modes for the channels and clients on those channels, that it
3695 announced to the router when it connected to it. The protocol
3696 specification has been updated accordingly.
3698 * The silc_server_new_channel did not handle the packet coming
3699 from normal server as it normally does not send that. However,
3700 when it announces its channels it does send it. Implemented
3701 the support for that.
3703 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
3704 into the file lib/silccore/id.h.
3706 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3708 * Fixed memory leaks in the functions silc_idlist_del_client,
3709 silc_idlist_del_channel and silc_idlist_del_server in the file
3710 silcd/idlist.c. All of those leaked like a sieve.
3712 * Fixed some small memory leaks in the client's function
3713 silc_client_notify_by_server.
3715 * Added functions into silcd/server.c: silc_server_announce_clients,
3716 silc_server_announce_channels and silc_server_announce_server.
3717 These functions are used by normal and router server to announce
3718 to its primary router about clients, channels and servers (when
3719 router) that we own. This is done after we've connected to the
3722 These functions effectively implements the following packet types:
3723 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
3724 and SILC_PACKET_NEW_ID_LIST.
3726 * Added new functions into the silcd/packet_receive.[ch]:
3727 silc_server_new_id_list, silc_server_new_channel_list and
3728 silc_server_new_channel_user_list to handle the incoming
3729 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
3731 * Added support of changing Channel ID in the function
3732 silc_server_replace_id. If the server that announces a channel
3733 to the router already exists in the router (with same name but
3734 with different Channel ID), router is responsible to send
3735 Replace ID packet to the server and force the server to change
3736 the Channel ID to the one router has.
3738 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
3739 client that the Channel ID has been changed by the router. The
3740 normal server sends this to the client. Client must start using
3741 the new Channel ID as the channel's ID.
3743 Implemented handling of this new type into lib/silcclient/client.c
3744 into the function silc_client_notify_by_server.
3746 * Added new function silc_idlist_replace_channel_id into the files
3747 silcd/idlist.[ch] to replace the Channel ID.
3749 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3751 * Call silc_server_command_identify_check always when processing
3752 the IDENTIFY command in silcd/command.c
3754 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3756 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
3757 send keepalive packets. The packet can be sent by clients,
3758 servers and routers.
3760 Added function silc_socket_set_heartbeat into the file
3761 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
3762 If not set, the heartbeat is not performed. The actual
3763 heartbeat is implemented in the low level socket connection
3764 library. However, application is responsible of actually
3767 Added silc_server_send_heartbeat to send the actual heartbeat
3768 packet into silcd/packet_send.[ch]. Server now performs
3769 keepalive with all connections.
3771 * Added silc_task_get_first function into lib/silcutil/silctask.c
3772 to return the timeout task with shortest timeout. There was a bug
3773 in task unregistration that caused problems. TODO has been
3774 updated to include that task system must be rewritten.
3776 * The client library will now resolve the client information when
3777 receiving JOIN notify from server for client that we know but
3778 have incomplete information.
3780 * Rewrote parts of silc_server_remove_from_channels and
3781 silc_server_remove_from_one_channel as they did not remove the
3782 channel in some circumstances even though they should've.
3784 * Encryption problem encountered in server:
3786 The LEAVE command used to send the Channel Key packet to the
3787 router immediately after generating it. However, the code
3788 had earlier sent Remove Channel user packet but not immediately,
3789 ie. it was put to queue. The order of packets in the router
3790 was that Channel Key packet was first and Remove Channel User
3791 packet was second, even though they were encrypted in the
3792 reverse order. For this reason, MAC check failed. Now, this
3793 is fixed by not sending the Channel Key packet immediately but
3794 putting it to queue. However, this is more fundamental problem:
3795 packets that are in queue should actually not be encrypted
3796 because packets that are sent immediately gets encrypted
3797 actually with wrong IV (and thus MAC check fails). So, packets
3798 that are in queue should be encrypted when they are sent to
3799 the wire and not when they put to the queue.
3801 However, the problem is that the current system has not been
3802 designed to work that way. Instead, the packet is encrypted
3803 as soon as possible and left to the queue. The queue is then
3804 just purged into wire. There won't be any fixes for this
3805 any time soon. So, the current semantic for packet sending
3808 o If you send packet to remote host and do not force the send
3809 (the packet will be in queue) then all subsequent packets to the
3810 same remote host must also be put to the queue. Only after the
3811 queue has been purged is it safe again to force the packet
3814 o If you send all packets immediately then it safe to send
3815 any of subsequent packets through the queue, however, after
3816 the first packet is put to queue then any subsequent packets
3817 must also be put to the queue.
3819 Follow these rules and everything works fine.
3821 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3823 * Added new function silc_server_remove_clients_by_server to
3824 remove all client entries from ID list when the server connection
3825 is lost. In this case it is also important to invalidate all
3826 client entires as they hold the invalid server entry. This
3827 fixes fatal bug when server has lost connection and will reconnect
3830 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3832 * Made some sanity checks to silc_server_daemonise like to check
3833 whether the requested user and group actually exists.
3835 * Added sanity check to SKE's silc_ske_responder_finish to check
3836 that the public and private key actually is valid.
3838 * Invalidate the client's nickname when receiving Replace ID
3839 packet and the Client ID is being replaced. This means that the
3840 server will query the nickname if someone needs it (client)
3843 * Sort the ID Cache in client library when the ID Cache data
3844 has changed (needs sorting).
3846 * Do not allow for SILC client to create several connections to
3847 several servers. The client does not support windows right now
3848 and generating multiple connections causes weird behaviour.
3850 Irssi-silc client does support windows and can handle several
3851 connections without problems, see: www.irssi.org and SILC plugin.
3853 * Fixed some places where client was added to the IDList. The
3854 rule of thumb is following (in order to get everything right):
3855 If the client is directly connected local client then the
3856 `connection' argument must be set and `router' argument must be
3857 NULL to silc_idlist_add_client function. If the client is not
3858 directly connected client then the `router' argument must
3859 bet set and the `connection' argument must be NULL to the
3860 silc_idlist_add_client function.
3862 * The funtion silc_server_packet_send_local_channel actually did
3863 not check whether the client was locally connected or not. It
3864 does that now. Fixed a bug related to LEAVE command.
3866 * Fixed Remove Channel User payload parsing bug in server's
3867 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
3869 * The server's silc_server_save_channel_key now checks also the
3870 global ID list for the channel as it might not be in the local
3871 list. Fixed a bug related to LEAVE command.
3873 * Is this the end of the [<unknown>] buglet that has been lurking
3874 around for a long time? A little for loop fix in server's
3875 silc_server_command_whois_parse that is used by both IDENTIFY
3876 and WHOIS command. At least, this was a clear bug and a cause
3877 of one type of [<unknown>] buglet.
3879 * WHOIS and IDENTIFY commands call the function
3880 silc_server_command_[whois/identify]_check function even if
3881 we are not router server.
3883 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3885 * Added --with-gmp configuration option. If set the GMP
3886 is always compiled in the SILC source tree. If not set then
3887 it is checked whether the system has the GMP3 installed. If
3888 it has then the GMP won't be compiled (the system's headers
3889 and library is used), if it doesn't have it then the GMP is
3890 compiled in the SILC source tree.
3892 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3894 * Changed RSA private exponent generation to what PKCS #1
3895 suggests. We try to find the smallest possible d by doing
3896 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
3897 not security fix but optimization.
3899 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3901 * Added new config entry [Identity] to fork the server and run
3902 it as specific user and group. A patch from Bostik.
3904 * Imported Dotconf configuration library into lib/dotconf.
3905 This will be used to create the SILC configuration files later.
3906 It will appear in the distsribution after this commit.
3908 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3910 * A big code auditing weekend happening. Auditing code for
3911 obvious mistakes, bugs and errors. Also, removing any code
3914 Removed files for being obsolete:
3916 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
3917 inline in the file lib/silcutil/silcbuffer.h)
3919 o lib/silcutil/silcbufutil.c (the header has inline versions)
3921 Changed code to fix possible error conditions:
3923 o The buffer formatting routines now check that the destination
3924 buffer really has enough space to add the data. This applies for
3925 both buffer formatting and unformatting
3926 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
3927 unformatting was changed to accomodate following rules:
3928 XXX_*STRING_ALLOC will allocate space for the data into the pointer
3929 sent to the function while XXX_*STRING will not allocate or copy
3930 the data into the buffer. Instead it sets the pointer from the
3931 buffer into the pointer sent as argument (XXX_*STRING used to
3932 require that the pointer must be allocated already). This change
3933 makes this whole thing a bit more consistent and more optimized
3934 (note that the data returned in the unformatting with XXX_*STRING
3935 must not be freed now). The routines return now -1 on error.
3937 o Tried to find all code that use buffer_format and buffer_unformat
3938 and added return value checking to prevent formatting and
3939 especially unformatting errors and possible subsequent fatal
3942 o Changed ske->x and ske->KEY to mallocated pointers in
3943 lib/silcske/silcske.h. Fixed possible data and memory leak.
3945 o Added return value checking to all *_parse* functions. Fixed
3946 many memory leaks as well.
3948 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
3949 so that buffer overflows would not happen. All code now also
3950 checks the return value as it can fail.
3952 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3954 * Added reconnection support to server if the normal server looses
3955 its connection to the router (for example if router is rebooted).
3956 The server performs normal reconnection strategy implemented
3957 to the server. Affected file silcd/server.c.
3959 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3961 * Added new packet type SILC_PACKET_SET_MODE that is used to
3962 distribute the information about changed modes (for clients,
3963 channels and clients channel modes) to all routers in the
3964 network. Updated the protocol specification accordingly.
3966 Added functions into silcd/packet_send.c and
3967 silcd/packet_receive.c: silc_server_send_set_mode,
3968 silc_server_set_mode.
3970 Added new files silcmode.[ch] into lib/silccore that implements
3971 the encoding and decoding of Set Mode Payload. Added new type
3972 SilcSetModePayload. Moved the definitions of different modes
3973 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
3975 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3977 * Oops, a little mistake in server's connection authentication
3978 protocol. The protocol is not ended with FAILURE but with
3979 SUCCESS if the authentication is Ok. :) Affected file is
3982 * Implemented NICK_CHANGE notify handling in server in the file
3983 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
3984 the local clients on the channel. After the changing nickname
3985 in router environment snhould work and the [<unknown>] nickname
3986 should appear no more.
3988 The silc_server_replace_id function that receives the Replace ID
3989 payload now sends the NICK_CHANGE notify type also in the file
3990 silcd/packet_receive.c
3992 * Changed WHOIS and IDENTIFY command to support the maximum amount
3993 of arguments defined in protocol specs (3328 arguments). This
3994 fixed a bug that caused problems when there were more than three
3997 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3999 * Added extra parameter, command identifier, to the
4000 silc_client_send_command so that explicit command identifier
4003 Changed that ID list routines uses specific command identifier
4004 when sending WHOIS/IDENTIFY requests to the server so that they
4005 can be identified when the reply comes back.
4007 Affected files lib/silcclient/command.[ch],
4008 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
4010 * Added `sender' argument to silc_server_packet_send_to_channel
4011 to indicaet the sender who originally sent the packet to us
4012 that we are now re-sending. Ignored if NULL. Affected file
4013 silcd/packet_send.[ch].
4015 * Added some server statistics support in silcd/server_internal.h
4016 SilcServerStatistics structure and around the server code. Also
4017 send some nice statistics information when client is connecting
4020 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4022 * Fixed channel ID decoding in server's JOIN command reply in
4023 silcd/command_reply.c
4025 * Fixed braodcasting of replace ID payload to not to send it if
4026 we are standalone server in silcd/packet_receive.c.
4028 * Fixed all channel message sending routines to not to send
4029 packets to clients that has router set, since they are routed
4030 separately in the same function earlier. Affects file
4031 silcd/packet_send.c and all channel packet sending functions.
4033 * In USERS reply, res_argv[i] are not allocated, the table
4034 is allocated. Thus changed that free the table, not its
4037 * In server's whois_check and identify_check if the client is
4038 locally connected do not send any WHOIS commands - they are not
4041 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4043 * Fixed some minor bugs in client when sending WHOIS command. The
4044 arguments was in wrong order.
4046 * Removed statis function add_to_channel from server in
4047 silcd/command.c that was previously used with the joining but
4050 * Tested USERS command in router environment successfully with two
4051 routers, two servers and two clients.
4053 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4055 * Reorganized the USERS command and command reply in client library
4056 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
4057 When the command is given by user we register a pending command
4058 callback that will reprocess the command after the reply has been
4059 received from the server. When reprocessing the packet we then
4060 display the information. Thus, the USERS information is displayed
4061 now in the command callback instead of in the command reply
4062 callback. The processing of the command is same as previously
4063 when server has sent the command reply in the JOINing process.
4065 * Added to USERS command in silcd/command_reply.c to join the client,
4066 we didn't use to know about, to the channel after we've created
4067 a client entry for it. Also, for clienet we did know already still
4068 check whether it is on the channel or not and add it if not.
4070 * Removed silc_server_command_join_notify as the function and its
4073 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4075 * Changed the client's pending command handling to the same as the
4076 server's pending command handling. It is also now possible to
4077 execute command reply functions from other command reply
4078 function as the function callbacks for commands and command
4079 replies are one and same. The pending commands are not static
4080 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
4081 in client connection context. Thus, pending commands are server
4082 connection specific as it is convenient.
4084 Changed the function silc_client_command_pending and
4085 silc_client_command_pending_del and added new function
4086 silc_client_command_pending_check. Removed the
4087 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
4090 * Added cmd_ident, current command identifier, to the client
4091 connection context in lib/silcclient/client.h to keep track on
4092 command identifiers used in command sending. Client's command reply
4093 function handling now supports the mandatory command identifiers.
4095 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
4096 funtions in client to fully support pending command callbacks.
4098 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
4099 as one of the arguments to the application in the command reply
4102 * NOTE: The FORWARDED flag is depracated. It used to be depracated
4103 before first releasing SILC but came back. Now it is removed again
4104 and should come back nomore. The FORWARDED flag was used only
4105 by the JOINing procedure by forwarding the command packet to router.
4106 Now, the JOINing procedure has been changed to more generic (due
4107 to various router environment issues) and FORWARDED is not needed
4108 anymore for anything. The protocol specification is yet to be
4111 Now, removed silc_server_packet_forward from server and the flag
4112 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
4114 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4116 * Renamed NAMES command to USERS command. The NAMES was named that
4117 due to historical reasons. Now it is renamed. Also, rewrote
4118 parts of the USERS command. The nickname list is not sent anymore
4119 by the server. Only Client ID and mode lists are sent in the USERS
4120 command. Changed this also to the protocol specification.
4122 The client now resolves the names and stuff after it receives
4123 the USERS list from the server when joining to the channel.
4125 * WHOIS and IDENTIFY commands has been changed to support multiple
4126 Client ID's per command. One can now search for multiple users
4127 in the network by sending only one WHOIS or IDENTIFY command.
4128 Changed the code and the protocol specifications.
4130 * Removed silc_server_command_identify_parse and changed that IDENTIFY
4131 uses silc_server_command_whois_parse to parse the request. */
4133 * If normal server, do not parse the WHOIS and IDENTIFY requests
4134 before sending it to the router. Saves some time.
4136 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Fixed JOIN command on client library. Wrong number of arguments
4139 used to crash the client.
4141 * Added silc_server_channel_has_global function to check whether
4142 channel has global users or not.
4144 * Added silc_server_channel_has_local function to check whether channel
4145 has locally connected clients on the channel.
4147 * The silc_server_remove_from_one_channel now checks whether the
4148 channel has global users or not after given client was removed from
4149 the channel. It also checks whether the channel has local clients
4150 on the channel anymore. If it does not have then the channel entry
4151 is removed as it is not needed anymore.
4153 * The silc_server_notify now checks on JOIN notify whether the joining
4154 client is one of locally connected or global. If it is global then
4155 the channel has now global users on the channel and that is marked
4156 to the channel entry. Also, it now saves the global client to
4157 global list who is joining and JOINs it to the channel. This is
4158 for normal server, that is.
4160 Changed silc_server_send_notify_on_channel,
4161 silc_server_packet_relay_to_channel and
4162 silc_server_packet_send_to_channel check if we are normal server
4163 and client has router set (ie. global client) do not send the
4164 message to that client, as it is already routed to our router.
4166 * Implemented LEAVE notify type handling in silc_server_notify
4169 * Tested LEAVE command in router environment successfully. Tested
4170 with two routers, two servers and two clients.
4174 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
4176 * Implemented SIGNOFF notify type handling in silc_server_notify
4179 * silc_server_remove_id now removes the client entry from all channels
4180 it has joined and thusly sends SIGNOFF notify type.
4182 * Rewrote the NAMES list generation in server by removing two excess
4183 loops. The lists are created now inside one loop.
4185 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4187 * silc_server_remove_channel_user checks now also global list
4188 for channel and client.
4190 * silc_server_new_channel_user checks now both local and global
4191 list for channel and client. Fixed a bug in client id decoding.
4192 Used to decode wrong buffer.
4194 * silc_server_channel_message checks now both local and global
4195 list for channel entry.
4197 * Tested channel joining (hence JOIN) in router environment
4198 successfully. Tested with two routers, two servers and two
4201 * Tested channel message sending in router environment successfully.
4203 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4205 * Added silc_server_save_channel_key into server.[ch] to save the
4206 received channel key in Channel Key payload processing. It is
4207 also used in JOIN command reply handling.
4209 Equivalent function silc_client_save_channel_key added into
4210 client.[ch] into client library.
4212 * Changed JOIN command reply to send information whether the channel
4213 was created or not (is existing already) and the channel key
4214 payload. Changed protocol specs accordingly.
4216 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
4217 the request was sent by ID and not by nickname. Crashed on
4220 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4222 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
4223 now correctly save the received data.
4225 * silc_server_free_sock_user_data now notifies routers in the
4226 network about entities leaving the network.
4228 At the same time implemented functions silc_server_remove_id
4229 and silc_server_send_remove_id to receive and send REMOVE_ID
4230 packets. The packet is used to notify routers in the network
4231 about leaving entities. The ID removed will become invalid in
4234 * Added function silc_idlist_del_server into server. Removes and
4235 free's server entry from ID list.
4237 * silc_server_private_message function now checks, if we are router,
4238 that the destination ID really is valid ID, naturally.
4240 * In router when NEW_ID packet is received (for new client) the
4241 hash of the Client ID is saved in the ID Cache but the
4242 client->nickname is set to NULL, instead of putting the hash
4245 IDENTIFY command now also checks that client->nickname must be
4246 valid. If it is not if will request the data from the server who
4247 owns the client. Added new function
4248 silc_server_command_identify_check.
4250 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
4251 to set the command to already allocated Command Payload.
4253 * Tested private message sending in router environment with two
4254 routers, two servers and two clients. Fixed minor bugs and now
4257 * Fixed segfault from client's NAMES command. Used to crash if
4260 * Forwarded packets must not be routed even if it is not destined
4261 to the receiver. Changed server code comply with this.
4263 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4265 * Added `require_reverse_mapping' boolean value to ServerParams
4266 structure. If TRUE (not default) the server will require that
4267 the connecting host has fully qualified domain name.
4269 If the reverse mapping is not required and hostname could not be
4270 found the IP address is used as hostname.
4272 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4274 * Implemented version string checking to both client and server.
4275 The check is incomplete currently due to the abnormal version
4276 strings used in development version of SILC.
4278 * Changed all command functions in server to use the new
4281 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4283 * Changed char *data to unsigned char *data in ID Cache system to
4284 support binary data as ID Cache data. Changed code to support
4285 binary data in lib/silccore/idcache.c.
4287 * Renamed silc_server_packet_relay_command_reply to
4288 silc_server_command_reply as it is normal packet receiving
4289 function. Rewrote the function to accept command replys for
4290 servers and not only for clients.
4292 * Mark remote router always as registered server if we are connecting
4293 to it. Otherwise, commands sent by the router to us are ignored.
4295 * All ID List find routines now returns the ID Cache Entry pointer
4296 as well if requested.
4298 * WHOIS command works now in router environment, tested with two
4299 routers, two servers and two clients.
4301 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
4302 in router environment (as it is almost equivalent to WHOIS) but
4303 hasn't been tested thoroughly. Added new functions:
4305 silc_server_command_identify_parse
4306 silc_server_command_identify_send_reply
4307 silc_server_command_identify_from_client
4308 silc_server_command_identify_from_server
4310 * Disabled route cache adding because adding two different ID's with
4311 same IP replaces the old cache entry thus giving wrong route.
4312 The entry->router->connection is always the fastest route anyway
4313 so route cache may not be needed. Of course, new routes maybe
4314 established after receiving the ID when the entry->router->connection
4315 might not be anymore the most optimal.
4317 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4319 * Add route cache for received ID for fast routing.
4321 * Added silc_server_packet_route to route received packet on router
4322 that is not destined to us.
4324 * Renamed silc_server_get_route to silc_server_route_get.
4326 * Added id_string and id_string_len fields into SilcServer to
4327 include encoded ServerID for fast comparing without excess
4328 encoding of the ID's.
4330 * Cleaned up WHOIS command on server side. Added following static
4333 silc_server_command_whois_parse
4334 silc_server_command_whois_check
4335 silc_server_command_whois_send_reply
4336 silc_server_command_whois_from_client
4337 silc_server_command_whois_from_server
4339 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
4340 arguments in command replies. All command functions should be
4341 updated to use this macro.
4343 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4345 * Minor typo fixes on command reply handling on server.
4347 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4349 * Added silc_server_command_add_to_channel internal routine to add
4350 the client to the channel after router has created the channel and
4351 sent command reply to the server.
4353 * Added generic silc_server_send_command to send any command from
4356 * Use static buffer with ID rendering instead of duplicating data.
4358 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4360 * Fixed a channel user mode bug when joining to a channel server gave
4361 everybody channel founder rights, oops.
4363 * We mark ourselves as the router of the incoming server connection
4364 if we are router ourselves. This way we can check in some packet
4365 sending functions whether it is locally connected server. For
4366 incoming router connections we put NULL.
4368 * For router sending packets locally means now always sending the
4369 packet cell wide; to local clients and local servers. For normal
4370 server sending packet locally means sending it to only local
4373 * Fixed the JOIN command to really work in router environment. If the
4374 channel is created it is always created by the router. Router is
4375 also responsible of making the initial joining to the channel,
4376 sending JOIN notify to the sending server and distributing
4377 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
4378 does not exist server doesn't do anything else but forward the
4379 command to the router which performs everything.
4381 * Added silc_server_send_channel_key function to send the Channel Key
4384 * Added silc_server_create_channel_key to create new channel key. The
4385 channel key is now re-generated everytime someone joins or leaves
4386 a channel, as protocol dictates. Note: channel->key_len is the
4389 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4391 * Splitted server.[ch] finally. Created now packet_send.[ch] and
4392 packet_receive.[ch] to separate packet sending and receiving
4393 routines. The server.[ch] now includes everything else including
4394 actual packet processing (writing and reading data) and other
4397 Renamed silc_server_private_message_send_internal to
4398 silc_server_send_private_message. The routine is still though
4399 used only to relay private messages as server does not send
4400 private messages itself.
4402 Renamed silc_server_new_channel to silc_server_create_new_channel
4403 and added new function sicl_server_new_channel that handles the
4404 incoming New Channel packet. Added also new sending function
4405 silc_server_send_new_channel to send New Channel Payload.
4407 * Added new function silc_server_notify to process incoming notify
4408 packet to the server/router. Server may then relay the notify
4409 to clients if needed.
4411 * Added new function silc_server_new_channel_user to process incoming
4412 New Channel User packet. Router will redistribute the packet and
4413 send JOIN notify to its local clients and locally connected servers
4414 if needed. Normal server will send JOIN notify to its local client
4415 on same channel when received this packet. Added also corresponding
4416 sending function silc_server_send_new_channel_user to sent the
4419 * Added boolean route argument to send_notif_to_channel and
4420 packet_send_to_channel functions to attempt to route the packet
4421 if it is TRUE and send only locally if it is FALSE.
4423 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4425 * silc_server_replace_id now broadcasts the received replace ID
4426 packet if it is not broadcast packet already. The router must
4427 broadcast to inform other routers about changed ID.
4429 * Added backpointer to server's router into SilcServer context in
4430 silcd/server_internal.h.
4432 * Fixed silc_server_packet_broadcast to send correct broadcast
4435 * The channel key is now distributed to the local client as soon
4436 as it is received from the router (in router environment) so that
4437 no other packet may be sent for the channel until client has
4440 * silc_server_remove_channel_user now broadcasts the received
4441 Remove Channel User packet if it is not broadcast packet already.
4442 The router must broadcast to inform other routers about removed
4445 * Added users field into SilcPacketContext that is a reference count
4446 of the context. One can increase the reference count by calling
4447 silc_packet_context_dup which is now changed to just increase the
4448 reference count instead of duplicating the data. The reference
4449 count is decresed by calling silc_packet_context_free that will
4450 free the data after the reference count hits zero.
4452 For now on the packet context and everything allocated into it
4453 (including the raw packet from network) must be freed by calling
4454 the new silc_packet_context_free function. Added also new function
4455 silc_packet_context_alloc that must be used now to allocate the
4456 context. This also means that if a routine is asynchronous from
4457 silc_[client/server]_packet_parse_type the packet context must
4458 be duplicated by calling silc_packet_context_dup. Otherwise it
4459 gets free'd after silc_[client/server]_packet_parse_type returns.
4460 Also, one must remember that if packet is duplicated then its
4461 reference count must be decresed by calling the free function as
4462 many times as it was duplicated.
4464 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
4465 from both client and server.
4467 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4469 * Made joining to a channel working in router environment.
4471 * Cleaned up JOIN command on server side and create function
4472 silc_server_command_join_channel internal routine to make the
4475 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4477 * Changed silc_command_pending list to SilcDList. Also, added
4478 `ident' field to SilcServerCommandPending structure to identify
4479 the reply and to call correct callback.
4481 Added silc_server_command_pending_check function to replace the
4482 corresnponding macro. The silc_command_pending list is not
4485 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
4486 to set identifier to previously allocated Command Payload. It
4487 is used to set identifier for command when resending Command
4490 * Added silc_command_payload_encode_payload to encode Command
4491 Payload buffer from SilcCommandPayload structure.
4493 * Added silc_argument_payload_encode_payload to encode Argument
4494 payload buffer from SilcArgumentPayload structure.
4496 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4498 * Changed WHOIS command to support router connection on server side.
4499 The whois request is always sent to router unless the server is
4500 standalone server. After server has received the reply from the
4501 router will it send the reply to the client.
4503 * Added silc_server_packet_broadcast into silcd/server.[ch] to
4504 broadcast received broadcast packet. The function is used only
4505 by router. The broadcast packet is always sent to the router's
4508 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
4509 render given ID to printable string, for log files for example.
4511 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4513 * Made basic router to router connections working. At least they
4514 can now connect to each other but nothing really works the way
4515 they are supposed - yet.
4517 * Added new initiator token to RouterConnection configuration
4518 file in silcd/serverconfig.[ch]. It is used to tell whether we
4519 are the initiator to the remote router or whether we'll expect
4520 the other end to connect.
4522 * Moved registering of listener task to silc_server_init, hence
4523 the server starts listenning as soon as it is run, even if it
4524 does not have connections to other routers. Let's see how well
4527 * Changed default connection retry timeouts for more suitable in
4530 * Removed cipher and such arguments from silc_idlist_add_client
4531 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
4532 Added new function silc_idlist_add_data to add the keys and stuff
4535 * Added SilcIDListData structure and added it to SilcClientEntry
4536 and SilcServerEntry as their first field in the structure. This
4537 way we can explicitly cast the ID entries to the SilcIDListData
4538 structure and get common data for the entries. In past, we had
4539 to first check what type of connection it is and then cast it to
4540 correct ID entry type. Now, we can directly cast the opaque
4541 pointer to the SilcIDListData (no matter what ID entry it actually
4542 is) and get the data needed.
4544 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4546 * Wow, found a bug in scheduler. The scheduler uninitialized itself
4547 in some circumstances even if threre were timeout tasks, though not
4548 IO tasks, but tasks anyway. Now fixed.
4550 * Defined SilcServerConnection structure to hold connection specific
4551 stuff about directly connected servers and routers. The definition
4552 is currently in silcd/server_internal.h. I thought about having
4553 a bit more important role fro this struct but for now it is used
4554 only when connecting to other server (or router actually).
4556 * Added connecting retry support in server when connecting to
4557 router(s). The retry feature implement exponential backoff
4558 algorithm. Also, added SilcServerParams structure to hold default
4559 parameters for server. For now, it include these retry settings
4560 and are hard coded. After server is moded to be as Silc Server
4561 Library this structure will be more important.
4563 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4565 * Changed client librarys channel->clients table to SilcList and
4566 changed code accordingly.
4568 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Changed client's channel table to SilcList and changed code
4571 accordingly. Also changed SilcChannelClientEntry to include back-
4572 pointer to the channel so that client entry can use that structure
4573 as list as well and we have fast cross-reference to the channel.
4574 This change dramatically decreased the complexity of channel
4575 handling with client entry and vice versa (removed one extra
4576 loop when searching for channel entry from many functions).
4578 * Changed server->sim from table to SilcDList and changed code
4581 * NAMES command can now be used from user interface. It will show
4582 the user list on the channel, neatly.
4584 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
4585 Code now saves realname of the user if it becomes available.
4587 * Renamed configure.in to configure.in.pre and made ./prepare
4588 script to automatically add correct version string to
4589 configure.in which it creates from configure.in.pre.
4591 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4593 * NAMES command reply now shows users mode with the nickname when
4596 * Moved silc_client_ch[u]mode[_char] functions from
4597 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
4598 place sucks, they are utility functions and should be in some
4601 * Fixed some unsigned int's to unsigned short's. Patch by cras.
4603 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
4606 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4610 * Added TRQ (efficient deque and list library) into lib/trq. This is
4611 a very good list library that is currently used in the SILC. Defined
4612 SilcList API over the library because I didn't like the API very
4613 much. See lib/trq/silclist.h for the API and examples of how to
4614 use the API. Fixed various places in the code to use the new
4615 SilcList API. The SilcList is meant for lists that has a structure
4616 already defined as a list. It is not suitable to add just some
4617 context to the list (in TRQ, the context is the list actually).
4619 So, I defined SilcDList that can be used for the purpose where
4620 predefined list structure does not exit. This can be used as
4621 such list. Now some context just can be added to the SilcDList.
4622 Currently this list is not used in the SILC just yet, though there
4623 are a lot places where this can replace dynamically allocated
4624 tables and I will fix these places, later, to use SilcDList.
4625 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
4626 and use TRQ internally).
4628 Also fixed some annoying warning messages that the original TRQ
4629 code generated. Also minor changes to TRQ's Makefile.in.
4631 * Added support for querying by Client ID to both WHOIS and
4632 IDENTIFY commands into server, as required by the protocol.
4634 * Removed method function pointers from SilcBuffer structure. They
4635 weren't used to anything and just increased the context size for
4636 no good reason. This change also made silc_buffer_alloc and
4637 silc_buffer_free functions inline functions.
4639 * Disabled command flooding detection support until it's fixed so
4640 that it accepts commands in but does not execute them more than once
4643 * Added silc_net_localhost(), to return local hostname, into
4644 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
4645 that must be initialized before calling silc_client_init.
4647 * Added new function: silc_server_send_notify_on_channels to send
4648 notify messages to all channels client has joined. It is assured
4649 that the message is sent only once per client.
4651 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
4652 lib/silcutil/silcutil.[ch] as silc_format function. The new
4653 function is generic and is used by server as well, not only by
4654 the logging routines.
4656 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
4657 the provided version string was not acceptable. Added new function:
4658 silc_ske_check_version into lib/silcske/silcske.h. The function
4659 must be implemented by the application (client or server) and it
4660 does not reside in the SKE library. The function checks the version
4661 string remote end sent.
4663 * Added back pointers (to opaque context and to SilcSocketConnection)
4664 into SilcPacketContext structure into lib/silccore/silcpacket.h.
4666 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
4667 duplicate packet context structure.
4669 * Changed `notify' client operation to send same arguments as client
4670 receives from server except for ID's. ID's are mapped to correct
4671 ID entry and that is returned. Also, if channel entry is not sent
4672 by server but the notify is for channel the channel entry is sent
4673 to application (otherwise application doesn't know that it is for
4674 channel (library gets it from packet's Destination ID)).
4676 * Added silc_client_remove_from_channels into client library to
4677 remove a client from all channels it has joined to. Used when
4678 received SIGNOFF notify from server. Added also new function
4679 silc_client_replace_from_channels to replace old ID entry with
4680 new ID entry on all channels. Used when received NICK_CHANGE
4683 * Fixed ID Cache list handling in silc_idlist_get_client in
4684 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
4685 to get (or query) client by ID.
4687 * Updated TODO list.
4689 * Added connection authentication status message defined by the
4690 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
4691 support for these into the code in client and server side.
4693 * Added generic function silc_client_send_command to send any command
4694 with variable argument list. Application should use this function
4695 to send commands if the command functions provided by the library
4696 does not suite for the application's user interface needs.
4698 * Added new `failure' client operation. Application is notified about
4699 received failure packet if client is executing a protocol. In this
4700 case the protocol's execution has failed.
4702 * Added SKE's end notify to send the SKE_SUCCESS notify message that
4703 is required by the protocol.
4705 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
4706 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
4709 * Added status flag to SilcSKE object to indicate realtime status
4710 of the SKE protocol.
4712 * Application receives now exactly same command reply arguments as
4713 the library receives from server. However, if ID is received the
4714 corresponding ID entry is returned to the application (eg. Client
4715 ID is mapped to correct SilcClientEntry entry and that is returned).
4716 Changed command_reply client operation due to this change.
4718 * Changed all ID's in commands and in command replys as ID Payloads.
4719 Change affected both client and server side codes.
4721 All ID's sent in SILC network (with execption of ID's in SILC
4722 Packet header) are sent in ID Payload to support variable length
4725 * Server now notifies nick changes and notifies all clients on
4726 the channels about the new nickname (about the new Client ID,
4729 * Implemented CMODE command to change channel modes. Supports all
4730 channel modes defined by the protocol specs except ban and invite
4731 lists. (Also, private channel key mode is supported but support for
4732 setting private channel key in client is missing, thus, this mode
4733 has no effect on client side (except that server requires that the
4734 client uses private channel key and normal channel traffic does not
4737 Also, invite mode works per se, but INVITE command does not work
4738 yet correctly, so you can set channel as invite only channel but
4739 inviting clients to the channel does not work (it is yet to be
4740 thought what's the best way to do it).
4742 * Added new command SILC_COMMAND_CUMODE to change user mode on the
4743 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
4744 Implemented CUMODE command to change user's mode on the channel.
4745 Supports all modes defined by the protocol specs.
4747 * Added NAMES command reply to return users modes on the channel.
4749 * Removed unnecessary and slow ciphers from lib/silccrypt.
4751 * Set SO_KEEPALIVE option to connection sockets by default.
4753 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
4755 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
4756 redefined the Notify Payload into protocol specs.
4758 * Added silc_id_payload_parse_id to get ID directly from raw
4761 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4763 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
4764 accept searching by Client ID as well.
4766 * Added support for LEAVE and SIGNOFF notify types in client library.
4768 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
4769 to parse ID Payload from raw data.
4771 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4773 * Added flags parameter into silc_ske_assemble_security_properties
4774 function in lib/silcske/silcske.[ch].
4776 * Changed notify client operation to fit better for notify messages
4777 sent by server. The notify payload received from server is now
4778 passed to the application (after parsing it to SilcNotifyPayload).
4779 It is application's responsibility to retrieve the arguments
4780 from the payload and show the message the way it wants. The message
4781 sent by server is implementation specific.
4783 * Changed public keys to comply with the protocol specification.
4784 Old public keys are not supported anymore and are not compatible.
4786 * Removed nickname from Channel Payload as the latest draft removed
4787 it. The client must resolve the nickname from the NAMES command
4788 reply received when it joined the channel.
4790 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
4792 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4794 * Fixed some errors in protocol specification drafts.
4796 * Created lib/silccore/silcnotify.c to implement Notify Payload
4797 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
4798 generic payloads described by protocol specifications. The file
4799 includes implementations for ID Payload and Argument Payload.
4801 * Changed Command Payload implementation to use the new Argument
4802 Payload. Changed command_xxxx_payload to command_payload_xxxx
4803 to comply with SILC coding conventions.
4805 * Added suppport for Argument Payload handling in Notify Payload
4806 implementation as protocol requires it. Added the new support
4807 into server and client lib as well.
4809 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4811 * Added support for multiple nicknames on same channel. [n] is
4812 added locally to the nickname if there are more than one same
4813 nicknames on the channel.
4815 * Server now sends all nicknames that matched WHOIS request.
4816 Client also shows the list received from server.
4818 * Added TOPIC command to client side. User can now set and show
4819 current topic on channel.
4821 * Added MOTD command to client and server. Also, server sends the
4822 motd when client connects to the server.
4824 * Changed version strings to comply ISO 8601.
4826 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4828 * Fixed protocol error handling in client library. It should now
4829 cope even if the SKE fails for some reason.
4831 * Made new protocol specification drafts for submitting to IETF.
4833 * Implemented TOPIC command to server in silcd/command.c.
4835 * Added two new notify types into lib/silccore/silcnotify.h:
4836 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
4837 notify nickname change and topic setting/change on a channel.
4839 * API change of command_reply operation in client library. The
4840 application gets now the status type received from server as well.
4842 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4844 * Removed the function just added to lib/silcutil/silcschedule.[ch].
4846 * Cras fixed and optimized the packet handling even further and
4847 it should work now. Minor change to the prototype of function
4848 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
4850 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4852 * Added new function into lib/silcutil/silcschedule.[ch]:
4853 silc_schedule_with_fd to select() a specified fd. The function
4854 returns after timeout expires or data arrives or goes. The
4855 function is used by packet routines to wait that all data is
4856 received from network.
4858 * Fixed data reading from network in lib/silccore/silcpacket.c.
4859 The code now assures that all data is read from the fd and then
4860 continues packet processing. This was a bug fix since the code
4861 used to drop some data in some circumstances.
4863 * Added new function into lib/silcclient/client.[ch]:
4864 silc_client_start_key_exchange to start key exchange after
4865 connection has been established to server. The code internally
4866 now uses this funtion but its main purpose was to provide it
4867 for applications that perform their own connecting. After
4868 application has created a connection it merely calls this
4869 function to start the key exchange between client and server.
4870 The library takes care of everything else after that.
4872 Updated also lib/silcclient/README to explain the usage of
4875 * Do not send to application information that connection has
4876 been established. Application gets notified it by connect
4879 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4881 * Applied cras's patch to add silc_schedule_one function. The
4882 function runs scheduler once and returns.
4884 * Fixed the scheduler after cras messed it up. The timeout
4885 handling works now as it's supposed to work.
4887 * Added into lib/silccore/ silcnotify.h to include notify
4888 message types support. Changed silc_server_send_notify*
4889 functions, in server.[ch], to support those new notify types.
4890 Added the support for the notify types into client library,
4891 as well. Added new notify client operation into ops.h in
4894 * Changed silc_server_packet_send_to_channel to send normal
4895 packets instead of just channel message packets. The function
4896 is now used to send the notify packets to channels. It is not
4897 used to send channel message packets anymore, as server never
4900 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
4901 va_arg()s as it seems to require it nowadays. I guess, if SILC
4902 is compiled with older va_arg() the new code should work anyway.
4904 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4906 * Splitted core library. Core library (lib/silccore) includes
4907 now only SILC protocol specific core (and common) components.
4908 Created new utility library (lib/silcutil) that includes more
4909 generic purpose stuff. The stuff for util library was taken
4910 from the old core library. This was minor and easy split.
4912 * Created SILC Client Library (lib/silcclient) that includes
4913 implementation of the SILC client without user interface. This
4914 was major move from silc/ directory. The code has been changed
4915 so that it is transparent towards the user interface. The
4916 silc/ directory includes now the same user interface as before
4917 and it uses the new client library. Read lib/silcclient/README.
4918 Basicly, the client library performs everything else related
4919 to SILC except user interface handling. Also, configuration
4920 files are considered to be part of user interface and library
4921 does not handle them.
4923 This change also changed a lot of structures, function naming etc.
4924 Most important change was that SilcClientWindow object was
4925 renamed to SilcClientConnection in the client library. Created
4926 also new file lib/silcclient/ops.h. Also added new files
4927 silc/local_command.[ch] and silc/client_ops.[ch].
4929 All these changes were made to make it easier for user interface
4930 designers to create what ever user interface for the SILC client
4933 It is also expected that the server will be moved to lib
4934 directory as well and SILC Server Library will be created;
4935 sometimes in the future.
4937 * Removed Local commands from lib/silccore/silccommand.h as
4938 they are application specific and new client library does not
4939 handle any of those anymore.
4941 * Several functions moved to lib/silcutil/silcutilc.[ch] from
4942 old client implementation in silc/.
4944 * Added support for callback functions in SILC_LOG_* macros.
4945 Application can now set its own callbacks that will be called
4946 instead of using the default functions that will always print
4947 the debug messages to stderr (or stdout). Also, debugging can
4948 now be disabled by setting silc_debug to FALSE and re-enabled by
4949 setting it to TRUE. Note, that logging will still work even
4950 if debugging is disabled.
4952 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
4953 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
4954 silc_log_reset_debug_callbacks.
4956 * To enable debugging in silc client one must give now -d
4957 option on command line.
4959 * Changed silc_schedule_init to automatically allocate task queues
4960 if they are not allocated before calling it.
4962 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4964 * Added GMP 3.1 into math library.
4966 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4968 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
4969 a channel in SILC network. The packet is used by servers and
4970 routers to notify other routers that user has left a channel.
4971 This little feature was missing until now. Added the feature
4972 to protocol specification as well.
4974 Added functions: silc_server_send_remove_channel_user and
4975 silc_server_remove_channel_user into server.[ch].
4977 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
4978 lib/silccore/silcpacket.h. However, they are not implemented
4981 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4983 * Fixed joining to a channel and sending channel messages
4984 between server and router. The channel message sending should
4985 now work inside a cell.
4987 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
4989 * Fixed the private message sending between server and router.
4990 The private message sending should now work inside a cell.
4992 * Added silc_server_replace_id into server.[ch] to replace
4993 existing ID in the SILC network.
4995 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
4996 and silc_idlist_replace_server_id into idlist.[ch] in server.
4998 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5000 * Fixed the server to server connections. Server can again now
5001 connect to router. Router to router connections probably does
5004 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5006 * Added dynamic protocol registering support. Now protocols can
5007 registered and unregistered on the fly. Patch by cras.
5009 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5011 * Added lib/contrib directory to hold routines that some platforms
5012 don't have but are needed by SILC.
5014 * Added getopt.c, getopt1.c and getopt.h from GNU C library
5015 into lin/contrib to provide getopt() and getopt_long() for
5016 those who don't have it.
5018 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5020 * Added AWAY command to client. When away message is set and
5021 client receives a private message packet the client automatically
5022 replies to the sender with the away message.
5024 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
5025 bug seemed to be the cause of recent problems when compiling
5028 * Added version detection support to SKE protocol specification
5029 and added the new changes to the SKE implementation as well.
5030 There were other minor changes in the SKE protocol as well.
5032 Many changes in lib/silcske/silcske.[ch] and in
5033 lib/silcske/payload.[ch].
5035 * Added ^U functionality, clear input line. Patch from cras.
5037 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5039 * Mainly small bugfixes on core library. Fixed some debugging
5040 logging and buffer overflow in silclog.c.
5042 * Updated config.sub and config.guess on the distribution tree.
5044 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Added command lagging support in server. Client may execute
5047 commands now only once in two seconds.
5049 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5051 * Optimized packet reception. MAC computation and checking is now
5052 also more optimized. A lot previously duplicated code is now
5053 used as generic by both client and server.
5055 * Fixed key pair generation in clientutil.c
5057 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5059 * Added into lib/silccore/silcbufutil.[ch] new function;
5060 silc_buffer_realloc.
5062 * Moved generic packet sending/encryption functions to
5063 lib/silccore/silcpacket.[ch] from client and server. Some
5064 rewriting of the functions.
5066 * Moved all generic packet reception/decryption functions to
5067 lib/silccore/silcpacket.[ch] from client and server. The
5068 packet processing is now much cleaner in both client and server.
5069 These were major changes in both client and server.
5071 * Created many common functions in server to do packet sending.
5072 Previously code were duplicated a lot, this has been removed
5075 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5077 * Rewrote major parts of the ID cache system. Don't know
5078 whether it is better now or not but at least the API is more
5081 * Major rewrite on ID cache stuff on client because of the ID
5082 cache API changes. Added idlist.c to client.
5084 * Also major rewrite on ID cache stuff on server as well.
5085 Major rewrite of idlist.[ch]. SilcXXXList's are now named
5086 SilcXXXEntry's. We won't keep anymore idlist specific pointers
5087 in hand, instead they are all put into the ID cache system now.
5088 All server_idlist_* routines uses ID cache now instead of
5089 traversing its own lists (those lists does not exist anymore).
5090 SilcIDList though still exists. Also, SilcXXXEntry's are
5093 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5095 * Finally made the SKE implementation compliant to the protocol
5096 specification. All mp integers are now binary encoded as
5097 opposed being HEX encoded.
5099 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
5102 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
5103 functions: silc_[encode/decode]_pem. Also added function
5104 silc_encode_pem_file to PEM encode with newlines ('\n') for
5107 * SILC public keys are now encoded either PEM or binary. Same
5108 option is for private keys as well. By default private keys
5109 are binary encoded and public keys PEM encoded. Silly HEX
5110 encoding were removed.
5112 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
5113 function to create fingerprints.
5115 * Fixed a bug in SHA1; does not change the original data anymore.
5117 * Partly implemented INFO command on client and server side.
5118 Fixed CLEAR command. Changes to SERVER command; show current
5119 server(s) when giving command without arguments. Added
5120 VERSION command to client.
5122 * Added check to server that unregistered connections cannot
5123 execute commands (unless it is specificly allowed).
5125 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5127 * Fixed screen refresh.
5129 * Fixed channel joining bug from client. On some circumstances
5130 client tried to join to a channel it had already joined.
5132 * Added public key verification process into client's protocol.c.
5133 The client now verifies the public key from user and saves
5134 it into ~./silc/serverkeys/ directory.
5136 Added into: clientutil.[ch]: silc_client_verify_server_key.
5138 * Changed SKE protocol's silc_ske_initiator_finish function
5139 to accept callback function that verifies the received public
5140 key. Removed old silc_ske_verify_public_key function.
5142 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5144 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
5145 silc_pkcs_private_key[_data]_set.
5147 * Made the password and public authentication more cleaner in
5148 server's protocol.c.
5150 * Removed historic and obsolete protocol `channel_auth' from
5151 both client and server.
5153 * Removed wrong way of sending command status messages from
5154 server to client in server's command.c. The old way violated
5155 protocol specification.
5157 Changes to silccore/silccommand.[ch]: removed
5158 silc_command_encode_status_payload -> not needed anymore,
5159 changed silc_command_encode_payload_va to accept extra
5160 argument on variable argument list. The argument type must
5161 now be provided to the function. Also, added new function:
5162 silc_command_encode_reply_payload_va which is same as
5163 normal command_encode_payload_va except command status type
5164 is provided as extra argument.
5166 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5168 * Added ~./silc directory handling. The directory includes the
5169 public and private keys for the client.
5171 Added silc_client_check_silc_dir, silc_client_create_identifier
5172 and silc_client_load_keys.
5174 * Implemented SILC protocol compliant public key. Added public
5175 and private key saving to and loading from files.
5177 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
5178 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
5179 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
5180 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
5181 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
5183 Implemented: silc_pkcs_save_[public/private]_key[_data] and
5184 silc_pkcs_load_[public/private]_key.
5186 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5188 * Added silc_server_get_route (route.[ch]) to get connection
5189 data for the fastest route for given ID.
5191 * Implemented INVITE command on client and server. The command
5192 were re-defined in the SILC Protocol Specification and the
5193 implementation now complies with the specification.
5195 * Implemented PING command on client and server.
5197 * Implemented NAMES command on client and server. The server side
5198 supports currently only normal server not router server yet.
5199 Some changes to NAMES definition in SILC protocol specification.
5201 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5203 * Implemented LEAVE command on client and server.
5205 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
5206 again. This change was made to the protocol as well. Server
5207 should not violate the protocol specification anymore.
5209 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
5211 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
5212 was tested. SOCKS4 was not but should work anyway.
