1 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
5 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
7 * Added `type' argument to silc_id_payload_parse_id function which
8 now returns the type of the ID to the sent pointer. Affected
9 file is lib/silccore/silcid.[ch].
11 * Added check for CMODE_CHANGE notify type that mode change is
12 allowed by the sender. Affected file silcd/packet_receive.c.
14 * Added check for CUMODE_CHANGE notify type that mode change is
15 allowed by the sender. Affected file silcd/packet_receive.c.
16 Added the ID type as CUMODE_CHANGE notify type as argument
17 to the `notify' client operation. Affected files are
18 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
20 * Added function silc_client_add_server to the client library.
21 Added support for resolving also channel and server info when
22 received unknown entity in notify packet. Affected files are
23 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
25 * Added function silc_command_get_status to return the command
26 status from the command reply's argument payload. Affected files
27 are lib/silccore/silccommand.[ch].
29 * Added check for KICKED notify type that the kicking is
30 allowed by the client. Affected file silcd/packet_receive.c.
32 * Created function silc_get_input which can be used to get input
33 (echo on or off) from user on command line. Affected files are
34 lib/silcutil/silcutil.[ch].
36 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
38 * Optimized silc_server_packet_relay_to_channel function.
39 Added new function silc_channel_message_payload_encrypt which
40 can be called directly if channel message payload needs to
41 be encrypted and is already encoded (no need to call _encode
42 function). Packet relaying is now done by router without any
43 extra memory allocations. Affected files are
44 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
47 * Fixed the INVITE notify handling. It took wrong arguments
48 as invite list and invite delete. Affected file is
49 silcd/packet_receive.c.
51 * Added check for TOPIC_SET notify type that the topic change is
52 allowed by the client. Affected file silcd/packet_receive.c.
54 * Added check for INVITE notify type that inviting is allowed by
55 the client. Affected file silcd/packet_receive.c.
57 * Changed the silc_server_client_on_channel to return the
58 SilcChannelClientEntry as well. Moved the function
59 silc_server_check_cmode_rights to server_util.[ch].
60 Affected files are silcd/server_util.[ch], silcd/command.c.
62 * Added function silc_server_check_umode_rights to check whether
63 changing client's user mode is allowed. Added check for
64 UMODE_CHANGE notify type that the umode change is allowed
65 by the client. Affected files are silcd/server_util.[ch],
66 silcd/packet_receive.c and silcd/command.c.
68 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
70 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
71 ID length. It ignored that ID can be IPv6 based as well.
72 Affected file lib/silccore/silcpacket.h.
74 * Fixed the silc_id_id2str and silc_id_str2id to take the
75 IPv6 address offset's into consideration. Affecte file is
76 lib/silccore/silcid.c.
78 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
80 * Fixed the internal Unix scheduler functions to check for
81 NULL context they may receive. The affected file is
82 lib/silcutil/unix/silcunixschedule.c.
84 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
86 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
87 can specify different directory with --home command line
88 parameter. Affected files irssi/src/silc/core/client_ops.c,
91 * SILC-specific commands aren't now executed if the active server
92 isn't of SILC-type, so there won't be problems with having
93 IRC and SILC protocol support in same client. Affected files
94 irssi/src/silc/core/silc-channels.c, silc-servers.c,
97 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
99 * Improved the signal support in SILC Schedule. Added new
100 function silc_schedule_signal_call which is used by application
101 to mark a signal to be called. It is now safe to perform
102 any kind of tasks in signal callbacks since it is guaranteed
103 that the application specified signal callback is called
104 after the signal is over. Affected files are
105 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
107 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
109 * Added `name' field to SilcChannelPrivateKey to represent
110 application given name for the key. Moved also the context from
111 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
112 Added the `name' argument also to the function
113 silc_client_add_channel_private_key.
115 Added function silc_client_current_channel_private_key to set the
116 current channel private key in use.
118 Added "change" command to KEY command which can be used to change
119 the current channel private key. Bound the command also to
122 Also affected files lib/silcclient/client_channel.c,
123 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
125 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
127 * Added silc_rng_get_byte_fast function in to the
128 lib/silccrypt/silcrng.[ch].
130 * Changed the interface of silc_packet_assemble and the
131 silc_packet_send_prepare. If silc_packet_assmble is now
132 called the application does not call silc_packet_send_prepare
133 because the library will call it automatically. These
134 interfaces now also return a reference to the outgoing buffer
135 which includes the assembled packet, which the application can
136 use to encrypt the packet.
138 Affected files are lib/silccore/silcpacket.[ch],
139 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
140 silcd/packet_send.c, server_backup.c and packet_receive.c.
142 * Fixed a packet sending bug on very high load, where outgoing
143 packet queue wasn't handled correctly and packets got corrupted.
144 Affected files are lib/silcutil/*/silc*sockconn.c,
145 lib/silcclient/client.c and silcd/server.c.
147 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
149 * Added macro SILC_PACKET_DATALEN which can be used during
150 packet assembling to check whether the data to be added to
151 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
152 len is truncated until it fits it.
154 Added checks for maximum length of channel message payload and
155 private message payload also.
157 Added checks for maximum packet length in server and in
160 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
161 lib/silcclient/client.c, lib/silccore/silcchannel.c and
162 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
163 lib/silcclient/client_prvmsg.c.
165 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
167 * Added silc_server_packet_queue_purge call to the
168 silc_server_disconnect_remote to assure that all data in the
169 queue before disconnecting is sent to the network. Affected
172 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
174 * Added the deleting of server's own ID cache entry to the
175 silc_server_free function. Free also everything else that
176 has been allocated in silc_server_init. The affected file
179 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
181 * Added functions silc_parse_version_string, silc_version_to_num,
182 and silc_ske_parse_version to parse SILC protocol style version
183 strings. Affected files lib/silcutil/silcutil.[ch] and
184 lib/silcske/silcske.[ch].
186 * Added new configuration params: version_protocol, version_software
187 and version_software_vendor to specify what version the remote
188 host must at least be to be able to connect to server. The vendor
189 string can be regex matched too. Added new function
190 silc_server_connection_allowed to check maximum number of allowed
191 connections, and allowed versions for incoming connections.
192 Affected files are silcd/server.c, server_util.[ch] and
195 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
197 * Added preliminary support for signals in scheduler. The
198 signals we care about are now blocked always when the scheduler
199 is locked. This way we can synchronise the use of signal with
200 scheduler. It is guaranteed that when signal occurs the scheduler
201 is not locked, and thus new tasks can be safely added to the
204 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
205 to silc_schedule_internal_init and silc_schedule_internal_uninit.
206 Added new platform specific routines
207 silc_schedule_internal_signals_[un]block and
208 silc_schedule_internal_signal_[un]register.
210 Added new functions to SILC Schedule API:
211 silc_schedule_signal_[un]register. Each signal that application
212 is going to use should be registered to the scheduler.
214 Affected files are lib/silcutil/silcschedule.[ch],
215 lib/silcutil/*/silc*schedule.c.
217 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
219 * Check for unauthenticated client and server in the
220 silc_server_new_client and silc_server_new_server functions.
221 Affected file silcd/packet_receive.c.
223 * Added function silc_string_is_ascii to check whether given
224 string is 7-bit ASCII string. Affected files are
225 lib/silcutil/silcutil.[ch].
227 * Added function silc_id_is_valid_server_id into the
228 silcd/serverid.c and added checking for valid Server ID's in
229 silc_server_new_server. The Server ID must always be based
230 on the server's public IP address.
232 * Added logging of DISCONNECT packet message in the server.
233 Affected file silcd/server.c.
235 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
237 * Changed all library interfaces that use Global RNG to also
238 accept SilcRng as argument. Affected files are
239 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
240 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
241 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
242 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
245 * Added function silc_pkcs_generate_key to the
246 lib/silccrypt/silcpkcs.[ch] for applications so that they
247 don't need to do pkcs->pkcs->init calls anymore.
249 * Remove SilcSocketConnection from the SFTP API since it really
250 wasn't needed there. The application has the information
251 saved in its contexts anyway and the SFTP layer doesn't need
252 know about it. Affected files lib/silcsft/silcsftp.h and
253 lib/silcsftp/sftp_[server/client].c.
255 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
256 The SilcSimContext is not SilcSim.
258 * Fixed possible buffer overflows in silc_id_render in the
259 lib/silcutil/silcutil.c.
261 * On EPOC the global crypto module lists are not used at all
262 in the crypto library. Added support for using the constant
263 algorithm list on EPOC. Affected files are
264 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
267 * Fixed the handling of third parameter of KICKED notify, since
268 it was mistakenly updated to SILC Protocol 1.0 even though it
269 is to be included in 1.1. Since it is not in 1.0 it is not
270 mandatory, and this fix now handles it only if it is provided,
271 and it is not error if it is not provided. Affected file
272 lib/silcclient/client_notify.c.
274 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
276 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
277 client. Affected file irssi/src/silc/core/client_ops.c.
279 * Merged with Irssi 0.8.4 from irssi.org CVS.
281 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
283 * Check for valid socket connection in client entries before
284 sending any messages. Fixes a crash, but doesn't fix some
285 other underlaying bug that is lurking there. Affected
286 file silcd/packet_send.c.
288 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
290 * $usermode, $cumode and $cumode_space expandos shouldn't do
291 anything with non-SILC server records. Affected file
292 irssi/src/silc/core/silc-expandos.c
294 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
296 * Fixed the silc_net_check_[host/local]_by_sock to support
297 IPv6 bound sockets as well. Now they can return IPv6 addresses
298 as well. Affected file lib/silcutil/silcnet.c.
300 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
301 Affected lib/silcutil/unix/silcunixnet.c.
303 * Fixed ID rendering (at least on some platforms, not NetBSD)
304 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
306 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
308 * Added silc_hash_public_key and silc_hash_public_key_compare
309 functions to be used with SilcHashTable. They can be used to
310 hash public keys and compare public keys in hash table. Affected
311 file lib/silcutil/silcutil.[ch].
313 * Added support for specifying multiple public keys for Client
314 connection section in server configuration file. This makes it
315 possible to accept multiple public keys from same host, or to
316 make a section that accepts any incoming host, and have the
317 accepted public keys listed in the section.
319 Added functions silc_sever_[find/get]_public_key, added the
320 support for this actually to all connection sections but only
321 the Client section is currently allowed to specify multiple
324 Affected files are silcd/server.c, server_internal.h,
325 command.c, protocol.c, server_util.[ch], packet_receive.c.
327 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
329 * Merged Irssi 0.8.2 from irssi.org CVS.
331 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
333 * If silc_debug is TRUE, also output standard logging messages
334 to stderr with the debug output.
336 Made silc_log_reset_all() flushing all channels before returning.
337 Also fixed some documentation typos.
339 Affected files are lib/silcutil/silclog.[ch].
341 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
343 * Fixed the server to check correctly the amount of connections
344 from single host, by checking also the type of the connection.
345 Fixed also the comparison of number of connections and number
346 of allowed connections. Affected files are silcd/server.c,
349 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
351 * Fixed the USERS command reply to save the user's mode on the
352 channel as well. Fixed JOIN command reply to check whether a
353 client is on channel already and not join it twice. Affected
354 file lib/silcclient/command_reply.c.
356 * Added new file silc-expandos.c into irssi/silc/core/ to return
357 various stuff for various signal for the statusbar etc. updating.
358 Now Irssi SILC client prints channel user modes etc. on the
361 * The user mode (like server/router operator changes) is now shown
362 on the Irssi SILC client's statusbar. The affected files are
363 irssi/src/silc/core/client_ops.c, silc-expandos.c.
365 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
367 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
368 to SILC_SCHEDULE_[UN]LOCK macros.
370 * Added more error printing to logs in server code. Affected
371 files silcd/server.c and silcd/protocol.c.
373 * Fixed -S option parsing in Irssi SILC Client. Affected file
374 irssi/src/silc/core/silc-core.c.
376 * Added silc_buffer_alloc_size function. Affected file is
377 lib/silcutil/silcbuffer.h.
379 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
381 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
382 constants. Affected files in
383 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
386 * Changed the internal SFTP Memory FS table to const. Affected
387 file lib/silcsftp/sftp_fs_memory.c.
389 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
391 * Fixed the buffer formatting and unformatting routines to
392 check the size of 64 bits types with sizeof(). Affected
393 file is lib/silcutil/silcbuffmt.c.
395 Mon Feb 25 17:19:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
397 * Removed 0.6.x backwards support.
399 Sun Feb 24 12:53:25 EET 2002 Pekka Riikonen <priikone@silcnet.org>
401 * Changed all integer type names:
402 [u]int[8/16/32/64] -> Silc[UInt/Int][8/16/32/64]. This is
403 to avoid collisions with other libraries using same type names
406 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
408 * Added `prefer_ipv6' argument to the functions
409 silc_net_gethostbyname[_async]. If it is TRUE it will return
410 IPv6 address over IPv4. If FALSE IPv4 address is returned
411 even if IPv6 address was found. Affected files
412 lib/silcutil/silcnet.[ch].
414 * Added support silc_net_create_connection[_async] to fallback
415 to IPv4 address if IPv6 address could not be used (like if
416 it doesn't work on a specific system). Affected file in
417 lib/silcutil/unix/silcunixnet.c.
419 Sat Feb 23 15:20:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
421 * Added silc_schedule_reinit function to do the enlarging
422 of the max tasks handling capabilities of the scheduler.
423 Affected files lib/silcutil/silcschedule.[ch].
425 Wed Feb 20 20:41:01 EET 2002 Pekka Riikonen <priikone@silcnet.org>
427 * Added automatic extern "C" { ... } for C++ compilers so the
428 application does not need to define them. Affected file
429 includes/silcincludes.h.
431 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
432 old name went against naming convention. Applications now
433 include "silcclient.h" instead of "clientlibincludes.h".
434 Removed includes/clientlibincludes.h, it is redundant now.
436 * Renamed includes/version.h to silcversion.h.
438 * Added really preliminary support for OS/2 into the util
439 library. Only thread & mutex API is implemented, others
440 are still to be implemented. Created the lib/silcutil/os2/
441 directory. Created also file includes/silcos2.h.
443 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
445 * Added preliminary BeOS support into the util library.
446 Created lib/silcutil/beos/, and implemented all the needed
447 functions to support SILC on BeOS. Created also file
450 Mon Feb 18 15:49:22 EET 2002 Timo Sirainen <tss@iki.fi>
452 * Added proper initializations to silc's irssi code, so it's
453 now possible to load it as module. Affected files
454 irssi/src/silc/core/silc-core.c,
455 fe-common/silc/fe-common-silc-core.[ch] and fe-text/silc.c
457 Sun Feb 17 19:02:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
459 * Merged latest Irssi (0.8.1) from the irssi.org's CVS into
462 * Fixed the silcdoc document generator to correct generate
463 docs from all kinds of filenames. Affected files are
464 util/robodoc/Source/generator.c, scripts/silcdoc/silcdoc
466 * ROBOdoc documented lib/silcutil/silcmemory.h.
467 Added also new function silc_memdup.
469 * Removed lib/silcutil/silcbufutil.h and moved those routines
470 to the lib/silcutil/silcbuffer.h.
472 Sun Feb 17 15:52:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
474 * Added `user_count' to the SilcChannelEntry which now tells the
475 number of users on the channel. The user count is now saved
476 in normal server of global channels as well. Affected files
477 silcd/server.c, idlist.h, packet_receive.c and command.c.
479 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to
480 include file utility functions.
482 * Fixed the lib/silcsftp/sftp_fs_memory.c to use silcutil routines
483 instead of calling directly OS routines.
485 * Fixed NICK change printing in Irssi SILC Client. Fixed
486 KICKED notify printing in Irssi SILC Client. Affected file
487 irssi/src/silc/core/client_ops.c.
489 * Fixed a NICK change bug in client library, to not recreate the
490 client_entry->channels hash table everytime nick is changed.
491 Affected file lib/silcclient/client.c.
493 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
495 * ROBOdoc documented the lib/silcske/silcske.h, and improved
496 the SKE interface a bit.
498 * Fixed padding problem in PKCS#1. The padding was not actually
499 random since the random number generator was used incorrectly.
500 This security bug affects only when encrypting with PKCS#1, and
501 it is not currently used at all in SILC. SILC only use signing
502 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
504 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>
506 * Rewrote the notify handling in Irssi SILC client to not call
507 the events as signals. Fixes problems with Perl support.
508 Affected files irssi/src/silc/core/client_ops.c, silc-channels.c.
510 * Send the auto-nicking NICK command in client library with
511 little timeout after connecting. The affected file is
512 lib/silcclient/client.c.
514 * Added following new config file settings:
515 channel_rekey_secs, key_exchange_rekey, key_exchange_pfs,
516 key_exchange_timeout, conn_auth_timeout, connections_max,
519 Implemented all the new config settings handling in the server.
521 Optimized the use of SKE Mutual flag usage. Use it only
522 if connection authentication protocol is not based in public

580 Affected files silcd/serverconfig.[c], server.[c].
582 * Splitted the doc/example_silcd.conf.in. Separated the crypto
583 algorithm parts and created new file silcalgs.conf, that
584 is now included from the example_silcd.conf.in.
586 * Optimized the silc_server_connect_to_router_second to take
587 the connection configuration object from the SilcServerConnection
588 object instead of finding it during the connecting phase.
589 Added the configuration object to SilcServerConnection struct.
590 Affected files silcd/server_internal.h, server.c.
592 Thu Feb 14 16:02:26 CET 2002 Pekka Riikonen <priikone@silcnet.org>

614 authentication to be set at the same time.
616 Added `prefer_passphrase_auth' setting in config file which
617 can be used to set to prefer passwd auth if both passwd and
618 public key is set. If not set, public key is preferred.
619 This has effect only when being initiator (responder will try
622 Added support for authentication with passphrase and public key
623 at the same time. The passphrase is tried first always since
624 it is faster to check.
626 Affected file silcd/serverconfig.[ch], server.c, protocol.[ch].
628 Wed Feb 13 12:46:25 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>

670 hash algorithm. Affected file lib/silccrypt/silcrng.c.
672 Sun Feb 3 17:20:52 EET 2002 Pekka Riikonen <priikone@silcnet.org>
674 * Fixed the file transfer's key agreement payload to include
675 zero port also if the hostname is NULL because it could not
678 Call file transfer monitor callback now also if error occurs
679 during key agreement protocol.
681 Changed the silc_client_file_send interface to return the
682 SilcClientFileError instead of session id. The session ID
683 is returned into pointer provided as argument.
685 Check that the file exists locally before sending the
686 file transfer request at all.
688 Affected file lib/silcclient/client_ftp.c, silcapi.h.

700 file lib/silcutil/silclog.c.
702 * Fixed the channel message payload decryption in the function
703 silc_channel_message_payload_decrypt to not modify the original
704 buffer before it is verified that the message decrypted
705 correctly. Otherwise, next time it is called with correct
706 channel key it won't encrypt since the payload is corrupted.
707 Affected file lib/silccore/silcchannel.c.
709 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

721 * Fixed a bug in hash table internal routine for traversing
722 the table with foreach callback. The current entry may
723 become invalid in the callback but it was referenced after
724 the callback returned.
726 Do not allow auto rehashing of hash table during the
727 silc_hash_table_foreach operation, for same reasons as it is
728 not allowed for SilcHashTableList. Affected files are
729 lib/silcutil/silchashtable.[ch].
731 Fri Feb 1 14:55:00 CET 2002 Pekka Riikonen <priikone@silcnet.org>
733 * Defined DLLAPI into silcincludes.h and silcwin32.h for

737 Thu Jan 31 23:34:33 EET 2002 Pekka Riikonen <priikone@silcnet.org>
739 * Fixed private message handling. It used some old code that
740 caused the client to crash. Affecte file is
741 lib/silcclient/client_prvmsg.c.
743 Thu Jan 31 19:06:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
745 * Added function silc_client_add_channel,
746 silc_client_replace_channel_id, and removed functions
747 silc_client_new_channel_id and silc_idlist_get_channel_by_id
750 * Added cross reference of the joined channels to the
751 SilcClientEntry, and changed the SilcChannelEntry's
752 users list to SilcHashTable. The affected files are
753 lib/silcclient/idlist.[ch].
755 * Fixed a bug in hash table tarversing. While the hash table
756 is traversed with SilcHashTableList the table must not be
757 rehashed. It is now guaranteed that auto rehashable tables
758 are not rehashed while tarversing the list. Also defined that
759 silc_hash_table_rehash must not be called while tarversing
760 the table. Added function silc_hash_table_list_reset that must
761 be called after the tarversing is over. The affected files are
762 lib/silcutil/silchashtable.[ch].
764 * Changed all hash table traversing to call the new
765 silc_hash_table_list_reset in server and in client library.
767 * Added function silc_client_on_channel to return the
768 SilcChannelUser entry if the specified client entry is joined
769 on the specified channel. This is exported to application as
770 well. Affected files lib/silcclient/client_channel.c, silcapi.h.
772 Wed Jan 30 19:14:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
774 * Fixed founder regaining problem with JOIN command on normal
775 server. The notify for mode change must be sent always and
776 not only if !cmd->pending. Affected file silcd/command.c.
778 * Fixed the WHOWAS command's reply sending to support the
779 lists correctly. Affected file silcd/command.c.
781 Wed Jan 30 11:11:47 CET 2002 Pekka Riikonen <priikone@silcnet.org>
783 * When sending JOIN command to router for processing the
784 sender's old command identifier was not saved back to the
785 sender's command context, fixed now. The affected file is
788 * Create the key in JOIN command of the router did not return
789 the channel key, added check for this. Affected file is
792 * Fixed a channel ID update bug in JOIN command reply. Do
793 not directly upgrade the ID but call the function
794 silc_idlist_replace_channel_id if the ID was changed.
795 Affected file silcd/command_reply.c.
797 * Fixed memory leaks from command calling if it would fail.
798 Affected file silcd/command.c.
800 Tue Jan 29 19:49:31 EET 2002 Pekka Riikonen <priikone@silcnet.org>
802 * Applied patches from cras:
804 Memory leak fixes around libaries, irssi window resize fix,
805 new silclist.h and silcdlist.h, all extern inline changed to
808 * Removed dotconf from lib/dotconf, not needed anymore.
810 * Removed TRQ from lib/trq, not needed anymore.
812 * Do more frequent heartbeats (5 minutes instead of 10 minutes)
813 with server connections. Later this will be configurable
814 in config file after new config file is done. Affected file
817 Tue Jan 29 10:35:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
819 * Fixed a crash in server related to channel announcements.
820 Affected file silcd/server.c.
822 Mon Jan 28 17:49:42 EET 2002 Pekka Riikonen <priikone@silcnet.org>
824 * Fixed memory leaks in silc_server_create_new_channel*
825 functions. Affected file silcd/server.c.
827 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
828 which ID was changed. This way the router will send the
829 user list for the channel again, and server won't be in
830 desync in some rare circumstances. Affected file is
831 silcd/packet_receive.c.
833 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>
835 * Check for NULL socket pointer in the function

844 * Fixed some header addition to Toolkit distribution in
845 lib/silcutil/Makefile.am and lib/trq/Makefile.am.
847 * Added lib/silcclient/client_ops_example.h as an template
848 file for application programmers to quickly start using
849 the SilcClientOperation functions in their application.
850 Updated the lib/silcclient/README as well to tell about this
851 nice file made available.
853 Sat Jan 26 10:45:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
855 * Call silc_server_remove_from_channels when removing client
856 entry when NO_SUCH_CLIENT_ID was received. Affected file
857 is silcd/command_reply.c.
859 Fri Jan 25 19:12:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
861 * Added server & router operator statistics updating. Affected
862 file silcd/packet_receive.c and silcd/command.c.
864 * Fixed the SERVER_SIGNOFF notify handling on normal server
865 not to save the history information for clients. Same was
866 fixed earlier in remove_clients_by_server function, but not
867 here. Affected file silcd/packet_receive.c.
869 * Raised the default connection-retry count from 4 to 7 in
870 server. Affected file silcd/server.h.
872 * Cancel any possible reconnect timeouts when we start the
873 key exchange. Affected file silcd/server.c.
875 * Do not reconnect on connection failure when SCONNECT was
876 given. Affected files silcd/server.[ch].
878 Tue Jan 22 18:19:36 EET 2002 Pekka Riikonen <priikone@silcnet.org>
880 * Removed assert()'s from the lib/silcclient/client_keyagr.c.
882 * Fixed the NICK command to always give the unformatted
883 nickname to the one giving the NICK command. If unformatted
884 nickname is cached already it will be formatted and the
885 local entry will always get the unformatted nickname.
886 Affected file lib/silcclient/idlist.c.
888 * Fixed some double frees from client library commands.
889 Affected file is lib/silcclient/command.c.
891 * Fixed CUMODE command in server to assure that no one can
892 change founder's mode than the founder itself, there was a
893 little bug. Affected file silcd/command.c.
895 Mon Jan 21 19:07:53 EET 2002 Pekka Riikonen <priikone@silcnet.org>
897 * Removed the SilcClientCommandDestructor from the client
898 libary, it is not needed anymore. Affected files are
899 lib/silcclient/silcapi.h, command[_reply].[ch],
900 client_notify, idlist.c.
902 * Fixed GETKEY command to first resolve client, and then
903 resolve the server only if the client was not found, instead
904 of resolving both at the same time. Affected file is
905 lib/silcclient/command.c.
907 * Added silc_client_start_key_exchange_cb and lookup the
908 remote hostname and IP address before starting the key
909 exchange with server. The affected file is
910 lib/silcclient/client.c.
912 * The server's public key is now saved using the IP address
913 of the server and not the servername for the filename.
914 The hostname public key filename is checked as an fall back
915 method if the IP address based filename is not found.
917 Fixed the GETKEY command to save the fetched server key
920 Print the remote server's hostname now when new key is
921 received during connection process. Affected file is
922 irssi/src/silc/core/client_ops.c.
924 * Return always our own public key to the client if it asks
925 for it with GETKEY command. Affected file silcd/command.c.
927 * Removed the use_auto_addr variable from default config
928 file since it was in wrong section. Affected file is
931 * Fixed TOPIC_CHANGE notification to not route it when it
932 was sent using silc_server_send_notify_to_channel function.
933 Affected file silcd/command.c.
935 * Fixed silc_server_send_notify_kicked to send the kicker's
936 Client ID also, it was missing. Affected files are
937 silcd/command.c, silcd/packet_send.[ch].
939 Thu Jan 17 18:59:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
941 * Do not save client history information in SERVER_SIGNOFF.
942 Fixes the bug in normal server that it does not detect
943 the client becoming valid after the server becomes back
944 online. Affected file silcd/server_util.c.
946 * Added `sock_error' field into the SilcSocketConnection
947 context. When error occurs during socket operation (read
948 or write) the error is saved. Added also new function
949 silc_socket_get_error to return human readable socket error
950 message. Affected files are lib/silcutil/silcsockconn.[ch],
951 lib/silcutil/unix/silcunixsockconn.c, and
952 lib/silcutil/win32/silcwin32sockconn.c.
954 * The server now prints the socket error message in the
955 signoff for client. Affected file silcd/server.c.
957 * Fixed the `created' channel information sending from router
958 to server in JOIN command. Checks now whether the channel
959 really was created or not and set it according that.
961 Fixed the JOIN command to use the client entry's current
962 ID during the joining procedure instead of the one it sent
963 in the command (it is checked though), since it can change
964 between the packet processing and command processing, and
965 would just case unnecessary pain in the client end. Affected
966 file silcd/command.c.
968 * Fixed a channel key payload sending to use correct channel
969 ID when the server was forced to change the channel's ID by
970 router. Router sent the key payload with the old Channel ID.
971 Affected file silcd/packet_receive.c.
973 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
975 * Call silc_server_save_channel_key only if the key payload
976 was provided in the JOIN command's command reply. Affected
977 file silcd/command_reply.c.
979 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
981 * Fixed silc_mp_sizeinbase to return the value correctly with
982 MPI. Affected file lib/silcmath/mp_mpi.c.
984 * Fixed the stop_server signal to correctly stop the scheduler
985 and gracefully stop the server when SIGTERM or SIGINT signals
986 are received. Affected file silcd/silcd.c.
988 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
990 * Simple handling of TERM and HUP signals. Also added some log
991 flushing call around. Affected file is
994 * Fixed small bugs in silclog.c. Now buffering output will take
995 effect after 10 seconds since startup: This will ensure that
996 no important startup messages are lost. Also output redirection
997 will preserve original format ([Date] [Type] message).
998 Affected file is lib/silcutil/silclog.c.
1000 * Added two options to the config file, in the logging section:
1001 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1002 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1004 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1006 * Do not print the warning about log files not being initialized
1007 more than once to avoid excess logging. Affected file is
1008 lib/silcutil/silclog.c.
1010 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1011 the SIM copying in make install in Makefile.am.pre.
1013 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1015 * Rewritten silclog APIs. Globally interesting changes follows:
1016 silc_log_set_files() changed to silc_log_set_file().
1017 silc_log_set_callbacks() changed to silc_log_set_callback().
1018 ROBOdoc documented silclog header file.
1019 SilcLogCb now returns bool to wether inihibit the default
1020 handler or not (to keep the old behaviour return always TRUE).
1021 The new APIs should also fix the problem of the
1022 silcd_error.log file that was written in the current directory.
1025 Log files streams will remain opened after silc_log_set_file()
1026 call, means less CPU usage notably on high traffic servers.
1027 File streams are now full buffered, and flushed to the disk
1028 every 5 minutes, lesses HD activity and CPU usage.
1029 Messages can be redirected, allowing admins to configure
1030 one single logfile for all server messages.
1031 the silc_log_quick global variable to activate fast-logging.
1032 Affected files lib/silcutil/silclog.[ch]
1034 * Changed some code to conform new silclog APIs. Affected
1035 files are doc/example_silcd.conf.in, silcd/server.c
1036 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1039 * Fixed a memory leak that could occur in some situations.
1040 Affected file silcd/serverconfig.c.
1042 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1044 * Added the silc_client_del_client to remove the client from
1045 all channels as well. Affected file lib/silcclient/idlist.c.
1047 * Fixed the client library to correctly remove the client
1048 from all channels when the client entry is being destroyed.
1049 Affected file lib/silcclient/client_notify.c, command.c.
1051 * Added auto-nicking support to the client library. If the
1052 applicatio now sets client->nickname it will be sent to the
1053 server after connecting by the library. This way for example
1054 SILCNICK (or IRCNICK) environment variables will have effect
1055 and always change the nickname automatically to whatever
1056 it is wanted. Affected file lib/silcclient/client.[ch].
1058 * Renamed silc_server_command_bad_chars to the
1059 silc_server_name_bad_chars and moved it to the
1060 silcd/server_util.[ch]. Added also new function
1061 silc_server_name_modify_bad to return nickname that
1062 includes bad characters as new nickname without those
1063 bad characters. This check and modify is now used in
1064 silc_server_new_client when the username is initially set
1065 as nickname, so it must be checked to be valid nickname.
1066 Affected file silcd/packet_receive.c.
1068 * The nickname length is now taken from the packet for real
1069 and not trusted to strlen() since it clearly can return
1070 wrong length for nickname including bad characters. This
1071 also applies to channel names. Affected file silcd/command.c.
1073 * Removed the lib/silcsilm/modules directory. Modules are now
1074 compiled into the lib/silcsim. Fixed the copying of the
1075 modules to follow symbolic links in Makefile.am.pre.
1077 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1079 * Fixed silc_string_regexify list creation. Fixes bugs with
1080 BAN and INVITE commands in server. The affected file is
1081 lib/silcutil/unix/silcunixutil.c.
1083 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1085 * Removed the command destructor entirely from the server's
1086 command and command reply routines. It is not needed, and
1087 its usage was buggy and caused crashes. Affected files are
1088 silcd/command[_reply].[ch].
1090 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1092 * Cancel protocol and NULL sock->protocol if timeout
1093 occurred during protocol. Affected file silcd/server.c.
1095 * Cancel protocol timeouts always before calling the final
1096 callback, to assure that after final callback is called
1097 no other state will be called for the protocol anymore.
1098 Affected file silcd/protocol.c.
1100 * Print error log if incoming connection configuration could
1101 not be found. Affected file silcd/server.c.
1103 * Fixed JOIN command to correctly save the founder mode
1104 to the client on normal SILC server, when the channel
1105 was created by the router. Affected file silcd/command.c.
1107 * Fixed LIST command (hopefully) to send correct reply
1108 packets. Affected file silcd/command.c.
1110 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1112 * The silc_packet_receive_process now returns FALSE if the
1113 read data was invalid packet, and TRUE if it was ok.
1115 The server now checks that if unauthenticated connection
1116 sends data and its processing fails the server will close
1117 the connection since it could be a malicious flooder.
1119 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1121 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1123 * Make sure the warning about error opening a log file is
1124 printed only once and not everytime it fails (produces
1125 too much useless log). Affected file lib/silcutil/silclog.c.
1127 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1129 * Made the silc_server_daemonise() function more readable.
1130 Affected file silcd/server.c.
1132 * Pid file is now optional, the user may comment it out from
1133 the config file. Removed define SILC_SERVER_PID_FILE, we
1134 don't need a default any longer. Affected file
1135 configure.in.pre, lib/Makefile.am.pre.
1137 * Make some use of the pid file. The server now dies at startup
1138 if it detects a valid pid file on his path. The server would
1139 die anyway in this circumstance, because of the bind() failure.
1140 Affected file silcd/silcd.c.
1142 * No longer compiling lib/dotconf.
1144 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1146 * Fixed JOIN command parsing not to crash. Affected file
1147 lib/silcclient/command.c.
1149 * Fied the NICK_CHANGE notify to add the new client entry
1150 even it is resolved. This removes an <[unknown]> nick
1151 thingy bug in the client. Affected file is
1152 lib/silcclient/client_notify.c.
1154 * Do not try to allocate 0 bytes (efence does not like it)
1155 in lib/silccore/silccomand.c when encoding payload.
1157 * Do not take IRCNICK as nickname in Irssi SILC client since
1158 it is not possible to set nickname before hand connecting
1159 the server (TODO has an entry about adding auto-nicking
1162 * Changed the silc_server_command_pending to check whether
1163 there already exists an pending entry with the specified
1164 command, command identifier and pending callback. This is
1165 to fix IDENTIFY and WHOIS related crashes that may register
1166 multiple pending commands with same identifier. Affected
1167 file silcd/command.c.
1169 * Fixed the server to reconnect to the router even if it
1170 was already reconnecting and EOF was received. This to
1171 fix a possibility that the server wouldn't ever try to
1172 auto-reconnect to the router. Affected file silcd/server.c.
1174 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1176 * Fixed the server's password authentication to use the
1177 length of the locally saved password, and not the one
1178 sent in the packet. Affected file silcd/protocol.c.
1180 * Fixed same password authentication problem in the
1181 Authentication Payload handling routines in
1182 lib/silccore/silcauth.c.
1184 * Yet another password authentication problem fixed with
1185 channel password handling in silcd/command.c.
1187 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1189 * If first character of string in silc_parse_userfqdn is '@'
1190 then do not parse it. Affected file is
1191 lib/silcutil/silcutil.c.
1193 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1195 * Fixed minor bug in IDENTIFY command reply sending, which
1196 caused various weird problems during JOIN when it was
1197 resolving names for users. Affected file silcd/command.c.
1199 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1201 * Fixed the IDENTIFY command reply sending to chech better valid
1202 clients. It was possible to send incomplete list of replies.
1203 Affected file silcd/command.c.
1205 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1207 * Added silc_client_command[s]_[un]register functions now to
1208 dynamically register the commands in client library. Removed
1209 the static table of commands. This allows the client library
1210 to call commands without causing the application to know about
1211 what commands library has called.
1213 Removed the INFO command reply kludge to detect when the command
1214 was called by library. Now library use its own command reply
1215 function for INFO command.
1217 Added function silc_client_command_call to call a command.
1218 Application can use it to call command, not access the structure
1221 Now all commands that are sent by the client library (not
1222 explicitly sent by application) use own command reply functions.
1224 Affected files around lib/silcclient/ and in
1225 irssi/src/silc/core/.
1227 * Fixed the WHOIS command reply sending to chech better valid
1228 clients. It was possible to send incomplete list of replies.
1230 Fixed the WHOIS and IDENTIFY to send the request to router
1231 if normal server did not do it and did not find any results.
1233 Affected file silcd/command.c.
1235 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1237 * Moved the internal data from SilcClient context into its
1238 own file, not accesible to application. Affected files
1239 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1240 and other files in client library.
1242 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1244 * Added doc/examples installation target in Makefile.am.pre.
1247 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1249 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1250 commands the found client entry will be removed from the
1251 cache, after notifying application about the error. Affected
1252 file lib/silcclient/command_reply.c.
1254 * Changed the /MSG to check for exact nickname user gave, and
1255 not let `nick' match `nick@host' if it is only one found. Now,
1256 user must type the exact nickname (like nick@host2) even if
1257 there are no more than one same nicks found. This is to avoid
1258 a possibility of sending nickname to wrong nickname since
1259 `nick' could match `nick@host'. Affected file is
1260 irssi/src/core/silc-servers.c.
1262 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1264 * Do not print "you are now server operator" or similar when
1265 giving /away command. Affected files are
1266 irssi/src/silc/core/client_ops.c, silc-servers.h.
1268 * Made the silc_server_command_pending_error_check to send
1269 the same command reply payload it received back to the
1270 original sender of the command. This way all arguments
1271 that was received by the server will be received by the
1272 client too. Affected file silcd/command.c.
1274 * Added the silc_idcache_add to return the created cache entry
1275 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1277 * Add global clients to expire if they are not on any channel.
1278 This is because normal server will never know if they signoff
1279 if they are not on any channel. The cache expiry will take
1280 case of these entries. This is done by normal servers only.
1281 The affected files are silcd/command_reply.c,
1282 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1284 * If server receives invalid ID notification for WHOIS or
1285 IDENTIFY and the ID exists in the lists, it is removed.
1286 Affected file silcd/command_reply.c.
1288 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1289 in client then client entry that it matches is searched and
1290 the nickname is printed on the screen for user. Affected
1291 file irssi/src/silc/core/client_ops.c.
1293 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1295 * Use cache entry expire time in the LIST command reply to
1296 purge old entries from the cache after the LIST command
1297 reply has been received. This way we don't have non-existent
1298 entries in the cache for too long. Affected file is
1299 silcd/command_reply.c.
1301 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1303 * If we are normal server, and we've not resolved client info
1304 in WHOIS or IDENTIFY from router, and it is global client,
1305 we'll check whether it is on some channel. If it is not
1306 then we cannot be sure about its validity and will resolve it
1307 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1308 file silcd/command.c.
1310 * Search channel by name (if possible) rather than by ID
1311 in IDENTIFY command's command reply. Affected file is
1312 silcd/command_reply.c.
1314 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1316 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1317 Updated specs and implemented it. Affected file silcd/command.c,
1318 silcd/packet_send.c and silcd/packet_receive.c.
1320 * Implemented the <founder auth> payload handling in the JOIN
1321 command. If provided all conditions for channel joining
1322 except requirement to provide correct passphrase can be
1323 overrided by the channel founder. Updated the protocol specs.
1324 Affected file silcd/command.c.
1326 Added support for founder auth in JOIN command in client
1327 library. Fixed the parsing of the JOIN command now to support
1328 all options as they should be. The affected file is
1329 lib/silcclient/command.c.
1331 * Optimized the WHOIS and IDENTIFY commands to send the request
1332 to router only if it includes nicknames or other names. If
1333 they include only IDs then check the local cache first before
1334 routing. Affected file is silcd/command.c.
1336 * Added channels topic announcements. Affected file is
1337 silcd/packet_receive.c and silcd/server.c.
1339 * Fixed the silc_server_send_notify_topic_set to really destine
1340 the packet to channel. Affected file silcd/packet_send.c.
1342 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1343 library. Affected file lib/silcclient/client_notify.c.
1345 * Added UMODE announcements. Affected file silcd/server.c.
1347 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1349 * Memory leak fixes in:
1351 lib/silcutil/silcsockconn.c
1352 lib/silcske/silcske.c
1353 lib/silcske/groups.c
1355 lib/silccrypt/silcpkcs.c
1356 lib/silccore/silccommand.c
1357 lib/silccore/silcidcache.c
1362 * ROBOdoc documented the lib/silcske/groups.h file and a
1363 bit changed the interface for better.
1365 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1367 * Update the client entry context in the ID cache after
1368 nick change. Affected file lib/silcclient/command.c.
1369 Fixes the CUMODE command when regaining founder privileges,
1370 and a little WHOIS problem.
1372 * Fixed silc_net_gethostbyname to correctly call the
1373 inet_ntop. Affected file lib/silcutil/silcnet.c.
1375 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1377 * Added IPv6 support checking to the configure.in.pre, added
1378 also --enable-ipv6 option to override the check. Affected
1379 file configure.in.pre.
1381 * The silc_thread_create now calls the start function
1382 directly if threads support is not compiled in. Removes
1383 ugly #ifdef's from generic code. Affected files are
1384 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1386 * Added silc_net_gethostby[name/addr]_async to asynchronously
1387 resolve. Affected files are lib/silcutil/silcnet.[ch].
1389 * Added support for rendering IPv6 based server, client and
1390 channel IDs. Affected file lib/silcutil/silcutil.c.
1392 * Added support for creating IPv6 based server IDs. Affected
1393 file is silcd/serverid.c.
1395 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1397 * Added silc_net_gethostby[addr/name] into the
1398 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1399 routines. Added silc_net_is_ip[4/6]. Affected file is
1400 lib/silcutil/unix/silcunixnet.c. All routines that take
1401 address as argument now supports both IPv4 and IPv6 addresses.
1403 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1405 * Fixed LIST command reply sending in server. Affected file
1408 * Server now sends the kicker's client ID in the KICK notify
1409 to the kicked client. Affected file silcd/command.c.
1411 * The client library now parses the kickers client ID and
1412 UI displays it. Affected files lib/silcclient/client_notify.c
1413 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1415 * Made all payload parsing function prototypes consistent.
1416 They all take now const unsigned char * and uint32 pair as
1417 the payload data instead of SilcBuffer. Changes all around
1418 the source tree. Other unsigned char* -> const unsigned char*
1419 changes around the tree as well.
1421 * Optimized SFTP client and server packet sending not to
1422 allocate new buffer for each packet but to recycle the
1423 first allocated buffer. Affected files are
1424 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1426 * Optimized the SFTP client to use SilcList instead of
1427 SilcDList for requests, because it is faster. Affected file
1428 is lib/silcsftp/sftp_client.c.
1430 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1431 into lib/silccore/silcid.[ch].
1433 Renamed silcpayload.[ch] into silcargument.[ch].
1435 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1437 * If client entry is deleted with active key agreement
1438 session, abort the session.
1440 The silc_client_abort_key_agreement now calls the completion
1441 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1443 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1446 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1448 * Don't use __restrict in older GCC's. Affected file is
1449 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1451 * silc_net_localhost now attempts to reverse lookup the
1452 IP/hostname. Affected file lib/silcutil/silcnet.c.
1454 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1455 command. It can be used to gain founder privileges at
1456 the same time when joining the channel.
1458 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1459 kicker's client ID as well. Updated protocol specs.
1461 Defined that the server must send SILC_COMMAND_IDENTIFY
1462 command reply with error status to client who sent
1463 private message with invalid client ID.
1465 Updated the protocol specification.
1467 * Added silc_server_send_command_reply to send any
1468 command reply. Affected file silcd/packet_send.[ch].
1470 * Added silc_id_payload_encode_data to encode ID payload
1471 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1473 * The server now send IDENTIFY command reply with error
1474 status if client ID in private message is invalid. Affected
1475 file silcd/packet_receive.c.
1477 * Save the server key file with server's IP address in
1478 the filename instead of hostname. The affected file is
1479 irssi/src/silc/core/client_ops.c.
1481 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1483 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1486 * Added libtool support for compiling shared objects in
1487 lib/silcsim. Affected file configure.in.pre and
1488 lib/silcsim/Makefile.am. Original patch by cras.
1490 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1492 * Pid file configuration, and server's config file fixes
1493 patch by toma. Updated CREDITS file.
1495 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1497 * Fixed silc_client_channel_message to not try to decrypt
1498 the message twice if it resolved the destination client
1499 information. This could cause of dropping one channel
1500 message. Affected file lib/silcclient/client_channel.c.
1502 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1504 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1505 lib/silcclient/client.c. This function is used when the SILC
1506 Client is run under some other scheduler, or event loop or
1507 main loop. On GUI applications, for example this may be
1508 desired to used to run the client under the GUI application's
1509 main loop. Typically the GUI application would register an
1510 idle task that calls this function multiple times in a second
1511 to quickly process the SILC specific data.
1513 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1515 * Fixed silc_server_drop() for dropping the supplementary
1516 groups as well, this could cause a security hole on some
1519 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1521 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1524 * Write PID file after dropping privileges. Added -F option
1525 to run server on foreground. A patch by debolaz.
1526 Affected files silcd/server.c, silcd/silcd.c.
1528 * Fixed MOTD to return the MOTD file server name. Affected
1529 file silcd/command.c.
1531 * Added INFO command reply handling to the Irssi SILC Client.
1532 Affected file irssi/src/silc/core/client_ops.c.
1534 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1536 * Fixed the silc_idcache_list_* routines to really support
1537 the dynamic list. Fixes a crash. Affected file is
1538 lib/silccore/silcidcache.c.
1540 * Fixed the LIST command reply to really call LIST command's
1541 pending callbacks. Affected file silcd/command_reply.c.
1543 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1545 * Update conn->local_entry->nickname after giving NICK
1546 command. Affected file lib/silcclient/command.c.
1548 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1550 * Added the [pid] option to the silcd configuration file
1552 Affected files: serverconfig.[ch] and silcd.c
1554 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1556 * Save fingerprint in WHOIS command reply in server.
1557 Affected file silcd/command_reply.c.
1559 * Fixed NICK commands pending callback registration.
1560 Affected file lib/silcclient/command.c.
1562 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1564 * Use ++server->cmd_ident when sending commands in server,
1565 instead of random number. Affected file silcd/command.c.
1567 * Fixed GETKEY command reply to call actually GETKEY pending
1568 command callbacks. Affected file silcd/command_reply.c.
1570 * A bit stricter check for nicknames. Check for same nickname
1571 in NICK command also. Affected file silcd/command.c.
1573 * Do not call INFO command everytime client ID changes, only
1574 during first connecting. Affected file lib/silcclient/client.c.
1576 * Set the new nickname only after successful command reply for
1577 NICK command is returned by server. Affected file
1578 lib/silcclient/command.c.
1580 * Remove nicknames from nicklist during server_signoff notify.
1581 Should fix /NAMES bit more. The affected file is
1582 irssi/src/silc/core/silc-channels.c.
1584 * Added `fingerprint' field to the SilcIDListData in the
1585 silcd/idlist.h to hold the fingerprint of the client's
1588 Send the fingerprint of the client's public key in WHOIS
1591 Affected files silcd/command.c, and silcd/idlist.[ch].
1593 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1594 create fingerprint from given data.
1596 * Show the fingerprint of the client's public key in WHOIS.
1597 Affected files irssi/src/module-formats.[ch] and
1598 irssi/src/silc/core/client_ops.c.
1600 * Format the multiple same nicknames also during JOIN and
1601 NICK_CHANGE notifys. Affected file is
1602 lib/silcclient/client_notify.c.
1604 * Do not print error on screen for invalid private message
1605 payload since it can come if someone is sending private
1606 messages with wrong key. Affected file
1607 lib/silccore/silcprivate.c.
1609 * Fixed multiple concurrent /PING crash. Affected file
1610 lib/silcclient/command.c.
1612 * Changed the wrong ID encoding. All IP addresses must be
1613 in MSB first order in encoded format. They were encoded
1614 wrong and was in LSB format. Affected files are
1615 silcd/serverid.c, lib/silcutil/silcutil.c.
1617 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1619 * Call the `connect' client operation through the scheduler
1620 in case of error. Affected file lib/silcclient/client.c.
1622 * Call the `failure' client operation even if the error
1623 occurred locally during a protocol. Affected file is
1624 lib/silcclient/protocol.c.
1626 * Added support of sending LIST command to router from normal
1627 server. This way normal server can get list of all channels
1628 in the network too. Fixed the channel list sending in the
1629 server too. Affected files are silcd/command.c, and
1630 silcd/command_reply.[ch].
1632 * Added silc_server_update_channels_by_server and
1633 silc_server_remove_channels_by_server. They are used during
1634 disconnection of primary router and in backup router protocol.
1635 Affected file silcd/server_util.[ch], silcd/server.c and
1636 silcd/server_backup.c.
1638 * Fixed channel adding to global list in IDENTIFY command
1639 reply in server. Affected file silcd/command_reply.c.
1641 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1643 * If the incoming packet type is REKEY or REKEY_DONE process
1644 that packet always synchronously. Fixes yet another MAC
1645 failed error on slow (dialup) connections. Affected file
1646 lib/silcclient/client.c and silcd/server.c.
1648 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1650 * Call check_version SKE callback for initiator too. Affected
1651 file lib/silcske/silcske.c.
1653 * Implemented fix for security hole found in the SKE that was
1654 fixed in the specification few days back; the initiator's
1655 public key is now added to the HASH value computation.
1656 Added backwards support for the old way of doing it too, for
1657 old clients and old servers. Affected file is
1658 lib/silcske/silcske.c.
1660 * Enabled mutual authentication by default in SKE. If initiator
1661 is not providing mutual authentication the responder will
1662 force it. This will provide the proof of posession of the
1663 private key for responder. The affected files are
1664 lib/silcclient/protocol.c and silcd/protocol.c.
1666 * Do not cache anymore the server's public key during SKE.
1667 We do mutual authentication so the proof of posession of
1668 private key is done, and if the server is authenticated in
1669 conn auth protocol with public key we must have the public
1670 key already. Affected file silcd/protocol.c.
1672 * Added new global debug variable: silc_debug_hexdump. If
1673 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1674 file lib/silcutil/silclog.[ch].
1676 * Fixed compilation warning due to char * -> const char *.
1677 Affected files lib/silcutil/silcnet.h, and
1678 lib/silccore/silcauth.[ch].
1680 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1682 * Fixed CMODE command when new channel key was created. If
1683 the creation failed the old key was removed. Next time giving
1684 same command would crash the server since the old key was
1685 freed already. Affected file silcd/command.c.
1687 * Fixed the silc_server_announce_get_channels to not crash
1688 on reconnect. Affected file silcd/server.c.
1690 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1692 * Added silc_log_set_debug_string function to set a regex
1693 string to match for debug output. Only the function names,
1694 or filenames matching the given debug string is actually
1695 printed. This way it is possible to filter out those debug
1696 strings that user is not interested in.
1698 Fixed a bug in silc_string_regexify.
1700 Affected files lib/silcutil/silclog.[ch], and
1701 lib/silcutil/unix/silcunixutil.c.
1703 * Changed the -d options in both server and Irssi SILC client
1704 to take the debug string as argument. Affected files
1705 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1707 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1709 * Added silc_hash_babbleprint to create a Bubble Babble
1710 Encoded fingerprint. The encoding is developed by Antti
1711 Huima (draft-huima-babble-01.txt), and it creates human
1712 readable strings out of binary data. Affected file
1713 lib/silccrypt/silchash.[ch].
1715 * Print the babble print now in addition of fingerprint as well
1716 in Irssi SILC client. Affected files are
1717 irssi/src/fe-common/silc/module-formats.[ch],
1718 irssi/src/fe-common/silc/core/client_ops.c.
1720 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1722 * Fixed a security problem found in SKE. The initiator's
1723 public key too is now added to the HASH hash value creation
1724 which is signed by the responder to create the SIGN value.
1725 This will prevent anyone in the middle to lie to the responder
1726 about the initiator's public key. If this is done now, the
1727 man in the middle will get caught. Updated the protocol
1730 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1732 * Better installation directory handling. Configure module
1733 paths and other paths automatically to example_silc* files
1734 in doc/. A patch by toma.
1736 * Fixed compiler warning from MPI library, and from SILC RNG.
1739 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1740 It can be configured with ./configure. A patch by toma.
1742 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1744 * Find correct make to use in prepare-clean. A patch by
1745 toma. Affected file prepare-clean.
1747 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1749 * Added irssi variables use_auto_addr, auto_bind_ip,
1750 auto_bind_port and auto_public_ip.
1752 * Changed the interface for silc_client_send_key_agreement
1753 in lib/silcclient/silcapi.h
1757 irssi/src/silc/core/silc-core.c
1759 lib/silcclient/silcapi.h
1760 irssi/src/silc/core/silc-channels.c
1761 lib/silcclient/client_keyagr.c
1764 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1766 * Added silc_pkcs_public_key_compare to compare two
1767 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1769 * Check that the client who set the founder mode on the
1770 channel is the same client that is giving the founder
1771 mode to itself. It is done by comparing the saved public
1772 key (it is saved even in the authentication is passphrase).
1773 Affected file silcd/command.c.
1775 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1777 * Do not process packet for disconnected socket connection.
1778 Affected file lib/silccore/silcpacket.c.
1780 * Process the DISCONNECT packet through scheduler in the
1781 client library. Affected file lib/silcclient/client.c.
1783 * Fixed the silc_client_packet_parse to not to increase
1784 the packet sequence number if the conn->sock and the
1785 current socket connection is not same. This can happen
1786 for example during key agreement when the conn includes
1787 multiple socket connections (listeners). Affected file
1788 lib/silcclient/client.c.
1790 * The sender of the file transfer request now provides also
1791 the pointer (listener) for the key exchange protocol. If
1792 the listener cannot be created then it sends empty key
1793 agreement and lets the receiver provide the listener.
1795 Added `local_ip' and `local_port' arguments to the
1796 silc_client_file_send. If they are provided they are used,
1797 if not then it will attempt to find local IP address, if
1798 not found or bind fails then the remote client will provide
1801 Affected files are lib/silcclient/client_ftp.c and
1802 lib/silcclient/silcapi.h.
1804 * Extended the FILE SEND command to support defining the
1805 local IP and port for key exchange listener. They are
1806 optional. Affected file irssi/src/silc/core/silc-servers.c.
1808 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1810 * Defined to WHOIS command reply the sending of fingerprint
1811 of the client's public key (if the proof of posession of the
1812 corresponding private key is verified by the server).
1813 Updated to the protocol specification.
1815 * Added support of receiving the client's public key's
1816 fingerprint in command reply in client library. Affected
1817 file is lib/silcclient/command_reply.c, and
1818 lib/silcclient/idlist.[ch].
1820 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1822 * Do not send over 128 chars long nickname to the server
1823 in NICK command. Affected file lib/silcclient/command.c.
1825 * Do not send over 256 chars long channel names to the server
1826 in JOIN command. Affected file lib/silcclient/command.c.
1828 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1830 * Assure that silc_server_close_connection cannot be called
1831 twice for same socket context. Affected file is
1834 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1836 * Send error message to application if opening file for
1837 writing during file transfer fails. Affected file is
1838 lib/silcclient/client_ftp.c.
1840 Remove all file transfer sessions for a client that we're
1841 removing from ID cache.
1843 Affected file is lib/silcclient/client_ftp.c.
1845 * Fixed silc_net_addr2bin to return correct address. Affected
1846 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1848 * Fixed file transfer session removing on signoff notify.
1849 Affected file irssi/src/silc/core/silc-servers.c.
1851 * Added the SilcClientFileError to be returned in the monitor
1852 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1853 Affected file lib/silcclient/silcapi.h.
1855 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1857 * Fixed a crash in silc_client_ftp_free_sessions and
1858 silc_client_ftp_session_free_client. Affected file
1859 lib/silcclient/client_ftp.c.
1861 * Added `disabled' field in the SilcChannelEntry in the server
1862 to indicate if the server entry is disabled. Affected file
1863 silcd/idlist.h, silcd/command[_reply].c.
1865 * SILC server adds now /var/run/silcd.pid everytime it is
1866 started. Affected file silcd/silcd.c.
1868 * Added silc_server_packet_send_clients to send a packet to
1869 the provided table of client entries. Affected file

1872 * Fixed a crash in client resolving in client_prvmsg.c in
1873 client library. Affected file lib/silcclient/client_prvmsg.c.
1875 * Do not actually remove the client directly from ID cache
1876 during SERVER_SIGNOFF, but invalidate it. This way we
1877 preserve the WHOWAS info for the client. Affected file
1878 silcd/server_util.c.
1880 * Fixed SERVER_SIGNOFF notify handling in the server. The
1881 server is now able to process incoming SERVER_SIGNOFF notify
1882 for a server that it doesn't even know about. It will remove
1883 the clients provided in the notify. Affected file
1884 silcd/packet_receive.c.
1886 * Check for partial packet in data queue after every packet that
1887 was found from the queue. Return and wait for more data if
1888 there is partial data in queue. Affected file is
1889 lib/silccore/silcpacket.c.
1891 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1893 * Added SilcClietFileError enum to indicate error in
1894 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
1895 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
1896 Affected files lib/silcclient/silcapi.h and
1897 lib/silcclient/client_ftp.c.
1899 * Check that newsize in silc_buffer_realloc is larger than
1900 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
1902 * Added better monitor of file transfers. It now monitors
1903 key agreement protocol during the file transfer too. Added
1904 error reporting too. Affected files
1905 irssi/src/silc/core/silc-servers.c,
1906 irssi/src/fe-common/silc/module-formats.[ch].
1908 * Wrote a help file for FILE command.
1910 * Added silc_rng_global_get_byte_fast to get not-so-secure
1911 random data as fast as possible. Random data is read from
1912 /dev/urandom if available and from the SILC RNG if not
1913 available. It is used in padding generation. Affected file
1914 lib/silccrypt/silcrng.[ch].
1916 * All packets in client library are now processed synchronously.
1917 Optimized packet processing a lot. Affected file
1918 lib/silcclient/client.c.
1920 * All server connection packets are processing synchronously
1921 now in server, to optimize packet processing. Affected file
1924 * Include files are installed now only in Toolkit distribution
1925 if make install is given. Affected files: all Makefile.am's.
1927 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1929 * Assure that silc_client_notify_by_server_resolve does not
1930 resolve the client information multiple times. If it cannot
1931 be found by the first it cannot be found at all. Affected
1932 file lib/silcclient/client_notify.c.
1934 * Fixed WHOWAS command reply calling. Affected file
1935 lib/silcclient/command_reply.c.
1937 * Removed all references to silc_idlist_get_client from the
1938 Irssi SILC client since that call is internal call used by
1939 the library. The Irssi SILC client will use now client
1940 retrieval functions found in silcapi.h.
1942 * Fixed a bug in resolving nickname info before sending
1943 private message. It used freed memory. Affected file
1944 irssi/src/silc/core/silc-servers.c.
1946 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1948 * Assure my_channels statistics cannot go negative in server.
1949 Affected files silcd/server.c, silcd/server_util.c.
1951 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1953 * Upgraded dotconf 1.0.2 to 1.0.6 in lib/dotconf.
1955 Tue Oct 23 13:51:19 EEST 2001 Pekka Riikonen <priikone@silcnet.org>

1961 lib/sftp/sftp_fs_memory.c.
1963 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
1965 * Added silc_net_localip to return local host's IP address.
1966 Affected file lib/silcutil/silcnet.[ch].
1968 * If key exchange or rekey protocol is active for a connection
1969 parse all packets syncronously since there might be packets
1970 in packet queue that we are not able to process without first
1971 processing packets before them. Affected file silcd/server,
1972 lib/silcclient/client.c.
1974 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
1975 whether library should continue processing the packet.
1976 Affected file lib/silccore/silcpacket.h.
1978 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
1979 SilcSFTPMonitorData to SFTP server to monitor various
1980 SFTP client requests. Affected file lib/silcsftp/silcsftp.h,
1981 lib/silcsftp/sftp_server.c.
1983 * Added silc_file_size to return file size. Affected file
1984 lib/silcutil/silcutil.[ch].
1986 * Implemented the file transfer support for the client library.
1987 Added preliminary support for simple client to client one-file
1988 transmission. Affected file lib/silcclient/client_ftp.c,
1989 lib/silccilent/client.[ch].
1991 * Added new local command FILE to the Irssi SILC Client.
1992 It is used to perform the file transfer. It has subcommands
1993 SEND, RECEIVE, SHOW and CLOSE. Affected files
1994 irssi/src/silc/core/client_ops.c,
1995 irssi/src/silc/core/silc-server.[ch].

2007 lib/silcutil/silcutil.[ch].
2009 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2011 * Resolve the client info when received private message or
2012 channel message for a client which nickname we don't know.
2013 Affected files lib/silcclient/client_prvmsg.c and
2014 lib/silcclient/client_channel.c.
2016 * Do not crash in /KEY if client is not connected. Affected
2017 file irssi/src/silc/core/silc-channels.c.
2019 * Added SilcClientStatus field to the SilcClientEntry in the
2020 lib/silcclient/idlist.h.
2022 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2023 is incomplete and is being resolved, it won't be resolved
2026 Make sure also that USERS command reply does not resolve
2027 twice information. Affected file is
2028 lib/silcclient/command_reply.c.
2030 Make sure that silc_client_get_clients_by_list does not
2031 resolve twice same information.
2033 * Check for valid client->id in the silc_server_free_client_data.
2034 Affected file silcd/server.c.
2036 * Fixed /GETKEY nick@server not to crash if the server entry
2037 is not found. Affected file lib/silcclient/command.c.
2039 * Fixed the silc_server_check_cmode_rights to check the
2040 requested modes correctly. Affected file silcd/command.c.
2042 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2044 * Better checks for non-printable chars in nick added.
2045 Affected file silcd/command.c.
2047 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2049 * Call the silc_server_udpate_servers_by_server in the
2050 primary router that comes back online in the backup resuming
2051 protocol. Otherwise it routes packets wrong. Affected file
2052 silcd/server_util.[ch], silcd/server_backup.c.
2054 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2056 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2057 lib/silcutil/silcbuffmt.[ch].
2059 * Redefined the SILC packet header to include the padding
2060 length. Affected file lib/silccore/silcpacket.[ch].
2062 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2063 length for maximum padding up to 128 bytes). Affected
2064 file lib/silccore/silcpacket.h.
2066 * Removed all backwards support for old 0.5.x MAC thingies.
2067 The SILC packet header change makes it impossible to be
2068 backwards compatible.
2070 * Send the ENDING packet with timeout in the backup resuming
2071 protocol. This is to assure that all routers has connected
2072 to the primary router. Affected file silcd/server_backup.c.
2074 * Changed the RNG to take the first IV from random data. It
2075 used to take it from zero actually. Changed the RNG also
2076 to use /dev/urandom during session. /dev/random is used
2077 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2079 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2081 * Changed the SILC packet header to have the first two bytes
2082 (the packet length) encrypted. Affected files aroung the
2083 code tree, lib/silccore/silcpacket.[ch]. Removed the
2084 SilcPacketCheckDecrypt callback. It is not needed anymore
2085 since the silc_packet_receive_process will determine now
2086 whether the packet is normal or special.
2088 * Implemented the unidirectional MAC keys. Affected files
2089 lib/silcske/silcske.c, silcd/protocol.c and
2090 lib/silcclient/protocol.c.
2092 * Implemented the packet sequence number to the MAC computation.
2093 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2094 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2095 lib/silcclient/protocol.c.
2097 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2099 * Allow backup router to announce servers. All servers
2100 announced by backup router are added to the global list
2101 automatically. Update hte server's socket to our primary
2102 router also when backup router announces a server.
2103 Affected file silcd/packet_receive.c.
2105 * Do not update the client->router in the function
2106 silc_server_udpate_clients_by_server if the client is on
2107 global list. We might fail to find any specific server
2108 for locally connected clients and local cell clients. They
2109 should still use the `from' and not `to' as client->router.
2110 This fixes backup router resuming protocol. Affected file
2111 silcd/server_util.c.
2113 * Decrease channel statistics count only if the channel
2114 deletion worked. Affected files are silcd/server.c and
2115 silcd/server_util.c.
2117 * Added silc_server_update_servers_by_server to update origin
2118 of all server entries. Used during backup router protocol.
2119 Affected files silcd/server_util.[ch], silcd/server.c. and
2120 silcd/backup_router.c.
2122 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2123 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2124 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2125 lib/silccrypt/silchmac.c.
2127 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2129 * Assure that router cannot reroute the same channel message
2130 to the sender. Affected file silcd/packet_receive.c.
2132 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2134 * Made better checks that the channel message is not sent
2135 to the router it came from. Affected file is
2136 silcd/packet_send.c. Fixed memory leak too.
2138 * Announce informations for incoming router connection, but
2139 only after checking if it is replaced by backup router.
2140 Affected file silcd/packet_receive.c.
2142 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2144 * Fixed the backup resuming protocol to work in multiple
2145 router environment. Affected file silcd/server_backup.c.
2147 * Route packet only to one router in the function
2148 silc_server_packet_send_to_channel. Affected file is
2149 silcd/packet_send.c.
2151 * Fixed silc_server_send_notify_dest to set the broadcast
2152 flag. Fixed the silc_server_send_notify_topic to actually
2153 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2154 Affected file silcd/packet_send.c.
2156 * Changed the SFTP Filesystem interface. Changed the
2157 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2158 the filesystem operation function. The SilcSFTPFilesystem
2159 is now a context that is allocated by all filesystem allocation
2160 functions and it already includes the operations structure
2161 and filesystem specific context. It is given as argument
2162 now to the silc_sftp_server_start. This made the interface
2163 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2164 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2166 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2168 * Changed the backup router adding and getting interfaces
2169 in the server. The router that will be replaced by the
2170 specified backup router is now sent as argument. Affected
2171 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2174 * Added silc_net_addr2bin_ne to return the binary form of
2175 the IP address in network byte order. Affected files
2176 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2178 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2180 * Check for existing server ID in silc_server_new_server
2181 and in silc_server_connect_to_router_final and remove the
2182 old entry if it exists. Affected file silcd/packet_receive.c,
2185 * Send the channel message always to only one router, either
2186 in upstream or downstream. Affected file is
2187 silcd/packet_send.c.
2189 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2191 * Wrote the definition of the backup resuming protocol to the
2192 protocol specification.
2194 * Removed one redundant channel key generation from normal
2195 server during joining procedure. Removed one redundant
2196 channel key sending from server to router during joining
2197 procedure. Affected file silcd/command.c.
2199 * Made minor bugfixes to the backup router resuming protocol.
2200 Affected file silcd/server_backup.c, server.c.
2202 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2204 * Added --disable-asm configuration option. Affected files
2205 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2208 * Implemented the backup resuming protocol that is used to
2209 resume the primary router position in the cell after the
2210 primary router comes back online. Affected files
2211 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2212 and silcd/server_util.[ch].
2214 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2216 * Sleep two (2) seconds after sending QUIT command to server.
2217 Affected file lib/silcclient/command.c.
2219 * Assure that if outgoing data buffer is pending do not force
2220 send any data. Affected file silcd/packet_send.c.
2222 * Assure that if outgoing data buffer is pending do not force
2223 send any data. Affected file lib/silcclient/client.c.
2225 * Implemented the backup router support when the primary router
2226 goes down. The servers and routers can now use the backup
2227 router as new primary router without loosing connectivity.
2229 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2231 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2232 in the server to indicate disabled entry. All data read
2233 from the connection will be ignored and no data is sent
2234 for entry that is disabled. Affected files are
2235 silcd/idlist.h, silcd/server.c.
2237 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2239 * Created SFTP client and server test programs in the
2240 lib/silcsftp/tests directory.
2242 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2244 * Implemented memory filesystem (virtual filesystem) for
2245 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2248 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2250 * Implemented the SFTP (SSH File Transfer Protocol) to the
2251 lib/silcsftp. It includes SFTP client and SFTP server
2254 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2256 * Moved lib/silccore/silcprotocol.[ch] to the
2257 lib/silcutil library.
2259 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2260 take variable argument list pointer as argument. Affected
2261 file lib/silcutil/silcbuffmt.[ch].
2263 * Added silc_buffer_set function that is used to set data
2264 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2265 Affected file lib/silcutil/silcbuffer.h.
2267 * Changed various routines in the core library to use the new
2268 silc_buffer_set instead of allocating new buffer only for
2271 * Added 64-bit value formatting and unformatting support to the
2272 silc_buffer_[un]format routines. Affected file is
2273 lib/silcutil/silcbuffmt.[ch].
2275 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2276 to includes/bitmove.h.
2278 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2280 * Fixed channel user mode saving in client library. Affected
2281 file lib/silcclient/command[_reply].c.
2283 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2285 * Defined the file transfer to the SILC Protocol. Added
2286 new packet type SILC_PACKET_FTP and defined File Transfer
2287 Payload. The mandatory file transfer protocol is SFTP
2288 (SSH File Transfer Protocol). Affected file in addition
2289 of the internet draft is lib/silccore/silcpacket.h.
2291 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2292 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2293 is used as part of backup router protocol when the primary
2294 router of the cell is back online and wishes to resume
2295 the position as primary router.
2297 * Redefined the MAC generation keys in the protocol. The
2298 same key is not used anymore in both direction. Both
2299 direction will now use different keys for sending and
2300 receiving. This fixes a potential security flaw. This
2301 change causes incompatibilities in the protocol.
2303 * Redefined also the MAC computation from the packet.
2304 An packet sequence number is now added to the MAC
2305 computation. This prevents possible replay attacks against
2306 the protocol. This change too causes incompatibilities
2309 Added `sequence' field to the SilcPacketContext to hold
2310 the current sequence number for the packet.
2312 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2314 * Added `created' field to the SilcIDListData in the file
2315 silcd/idlist.h to indicate the time when the entry was
2318 * Added `created' field to the SilcChannelEntry too. Affected
2319 file silcd/idlist.h.
2321 * Added `creation_time' aguments to all the announcement functions
2322 in the server. If it is provided then only the entries that
2323 was created after the provided time frame are actually
2324 announced. Affected file silcd/server.[ch].
2326 * The protocol says that the Channel ID's IP address must be
2327 based on the router's IP address. Added check for this in
2328 the silc_server_new_channel when processing incoming New Channel
2329 Payload. Affected file silcd/packet_receive.c.
2331 * Print out the correct version with --version in SILC client.
2332 Affected file irssi/src/silc/core/silc-core.c.
2334 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2336 * Fixed WHOWAS command to check for completnes of the client
2337 entry always, not just when the command is coming from client.
2338 Affected file silcd/command.c.
2340 * Added new function silc_server_packet_queue_purge to purge the
2341 outgoing data queue to the network. After the function returns
2342 it is guaranteed that the outgoing packet queue is empty.
2343 Affected file silcd/packet_send.[ch].
2345 * Purge the outgoing packet queue in the rekey protocol's final
2346 callback to assure that all rekey packets go to the network
2347 before quitting the protocol. Affected file silcd/server.c.
2349 * Added silc_client_packet_queue_parse as similar function as
2350 in server to the client library. The affected file is
2351 lib/silcclient/client.c.
2353 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2355 * Splitted silcd/server.c and created silcd/server_util.[ch]
2356 for utility functions.
2358 * Added new socket flag SILC_SF_DISABLED to indicate that the
2359 connection is open but nothing can be sent to or received from
2360 the connection. Affected file lib/silcutil/silsockconn.[ch].
2361 The checking for disabled socket is checked in the low level
2362 silc_socket_write and silc_socket_read functions.
2364 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2366 * Allow only nicknames and channel names that fits into the
2367 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2369 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2371 * When processing JOIN command reply in server check that if
2372 the channel exists in our global list we'll move it the local
2373 list. Affected file silcd/command_reply.c.
2375 * Fixed the check whether client is joined on the channel already
2376 in JOIN command. Affected file lib/silcclient/command.c.
2378 * Fixed the JOIN command reply to check whether the channel
2379 already exists. Affected file lib/silcclient/command_reply.c.
2381 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2383 * Added silc_ske_status_string to map the SKE error numbers
2384 to readable strings. The affected files are
2385 lib/silcske/silcske[_status].[ch].
2387 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2389 * Do not show the private channels on the WHOIS channel list
2390 as it is not allowed by the protocol. The affected file is
2393 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2395 * Assure that the packet length digged from the actual packet
2396 is something sensible in the silc_packet_decrypt_rest_special
2397 in lib/silccrypt/silcpacket.c.
2399 * Free and NULL the allocated pointer in silc_hmac_alloc if
2400 the HMAC allocation fails. The affected file is
2401 lib/silccrypt/silchmac.c.
2403 * Print the selected security properties to the log files in
2404 the server. Affected file silcd/protocol.c.
2406 * Add SKE's reference counter even if calling the completion
2407 callback manually. Otherwise it goes negative, although it
2408 does not cause any problems. The affected file is
2409 lib/silcske/silcske.c.
2411 * Remove the client entry with short timeout after giving the
2412 KILL command. Affected file lib/silcclient/command.c.
2414 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2415 case all found clients are already disconnected (WHOWAS would
2416 found them) in the server. Affected file silcd/command.c.
2418 * Update the last_receive (time of last data received) to be
2419 updated only when received private or channel message so that
2420 the idle time showed in WHOIS makes more sense.
2422 * Added boolean field `valid' in to the SilcClientEntry in the
2423 client library to indicate whether the entry is valid or not.
2424 This fixes the nickname change bug on channel when changing
2425 the nickname to be same than the old (like nick to Nick) the
2426 nickname formatter doesn't set the new nick anymore to Nick@host.
2427 Affected file lib/silcclient/idlist.[ch].
2429 * Now actually fixed the nickname changing on disconnection.
2430 Added new function silc_change_nick to the Irssi SILC Client.
2431 Affected file irssi/src/silc/core/client_ops.c,
2432 irssi/src/silc/core/silc-nicklist.[ch].
2434 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2436 * Check that the public key exists in the GETKEY command before
2437 trying to encode it. Affected file silcd/command.c.
2439 * Print some notifications on received public keys with GETKEY
2440 command in the Irssi SILC Client. Affected files are
2441 irssi/src/fe-common/silc/module-formats.[ch],
2442 irssi/src/silc/core/client_ops.c.
2444 * Use IDENTIFY command to resolve the server information in the
2445 GETKEY command instead of INFO command. Affected file
2446 lib/silcclient/command.c.
2448 * All command reply functions in the client library now calls
2449 the pending command reply callbacks even if an error has
2450 occurred. The server has done this a long time and now it was
2451 time to move the client library to this as well. Now all
2452 errors can be delivered back to the pending command reply
2453 callbacks if necessary. Affected files are
2454 lib/silcclient/command[_reply].[ch].
2456 * Change the nickname on disconnection back to the username
2457 because in reconnect the server will enforce it to it anyway.
2458 Affected file irssi/src/silc/core/silc-servers.c.
2460 * Fixed a config file parsing bug in the Irssi SILC client.
2461 Affected file irssi/src/silc/core/clientconfig.c.
2463 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2465 * When printing the channel mode on JOIN, verify that the
2466 channel key and channel's HMAC are valid. Affected file
2467 irssi/src/silc/core/client_ops.c.
2469 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2471 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2472 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2473 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2475 * Removed channel key rekey task deleting from the function
2476 silc_server_save_channel_key. Affected file silcd/server.c.
2477 Added explicit timeout task context instead that is used to
2478 delete the task if we are registering a new task before the
2479 new task has elapsed.
2481 * When channel key rekey occurs the client library now saves
2482 the old channel key for a short period of time (10 seconds) and
2483 is able to use it in case some is still sending channel
2484 messages encrypted with the old key after the rekey. Affected
2485 file lib/silcclient/[idlist.h|client_channel.c].
2487 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2489 * Added check to the silc_server_new_id_real to not accept
2490 new ID if it is the sender's own ID. Affected file is
2491 silcd/packet_receive.c.
2493 * Assure that we do not announce ourself or the one we've
2494 sending our announcements when we're router and are announcing
2495 servers to our primary router. Affected file silcd/server.c.
2497 * Fixed silc_server_command_identify_check_client to assemble
2498 correct WHOIS packet. It send corrupted WHOIS packet and
2499 caused problem with router to router connections. Affected
2500 file silcd/command.c.
2502 Fixed also silc_server_command_whois_check the same way
2503 as for the IDENTIFY command.
2505 * Added new SilcIDListStatus to the server in the SilcIDListData
2506 structure. The status now includes the current status of
2507 the entry (like registered, resolved etc.). Affected file
2508 silcd/idlist.[ch]. Defined a bunch of different status types
2509 as well. This replaced the old boolean registered field as well.
2511 Added resolve_cmd_ident field to the SilcClientEntry structure
2512 too so that if the entry is for example being resolved so
2513 another command may attach to the same pending command reply
2514 without requiring to resolve the same entry again. This concept
2515 should optimize the WHOIS and the IDENTIFY resolving under
2516 heavy load by taking away unnecessary resolving for entries
2517 that are being resolved already.
2519 Added support for adding multiple pending commands for one
2520 command idenfier. Affected file silcd/command[_reply].[ch].
2522 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2523 before deleting the data. Otherwise the hash table will have
2524 freed data in comparison functions. Affected file is
2525 silcd/command_reply.c.
2527 * Fixed silc_idlist_replace_client_id to add the new entry to
2528 the cache with NULL nickname. Otherwise there will be invalid
2529 memory as the nickname after the nickname is freed. Affected
2530 file silcd/packet_receive.c.
2532 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2533 saved into wrong slots because the previous number of entries
2534 was not taken into account. Affected file silcd/idlist.c.
2535 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2537 * If we are router and we receive JOIN notify to a channel that
2538 does not have any users then notified client is marked as the
2539 channel founder, as it is it. The affected file is
2540 silcd/packet_receive.c
2542 * Added to the extended hash table API's table_del_*ext functions
2543 the destructor as argument too, so that the caller can decide
2544 which destructor to use or whether to use destructor at all.
2545 Affected file lib/silcutil/silchashtable.[ch].
2547 * Fixed ID Cache purging. It actually deleted the entries from
2548 the hash table after the data was freed. The hash table ended
2549 up comparing freed memory. The affected file is
2550 lib/silccore/silcidcache.c.
2552 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2554 * Fixed Irssi SILC client's KILL command's HELP syntax.
2556 * The USERS command now resolves the detailed user information
2557 if the userinfo field is missing. Affected file is
2558 lib/silcclient/command_reply.c.
2560 * Do not print error in silc_file_read if the read file does
2561 not exist. Just silently return NULL. Affected file is
2562 lib/silcutil/silcutil.c.
2564 * Fixed the silc_log_output to not wine about NULL filename
2565 and to not create some bogus " " filename. Affected file is
2566 lib/silcutil/silclog.c.
2568 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2570 * Fixed various printing bugs on the user interface in the
2571 Irssi SILC Client. Minor changes that were forgotten from
2574 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Fixed the configure.in.pre and the compilation and distribution
2577 environment to support the new autoconf 2.52. That version is
2578 now required to compile the CVS trunk.
2580 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2582 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2583 to generally parse user@fqdn format strings. Affected file
2584 lib/silcutil/silcutil.c.
2586 * Added nickname_format and nickname_force_format fields to the
2587 SilcClientParams structure. The first one defines the format
2588 for the nicknames that the library will enforce if the receives
2589 multiple same nicknames. The second one is boolean value and
2590 can be used to force the library to always enforce the format
2591 to the nicknames regardles whether there are multiple nicknames
2592 or not. This configurable formatting was employed to flexibly
2593 support accessing multiple nicknames from the user interface.
2594 The userinterface can now set the nicknames to what ever format
2595 they prefer. Affected file lib/silcclient/silcapi.h.
2597 Added function silc_client_nickname_format to the file
2598 lib/silcclient/idlist.c. It performs the nickname formatting.
2600 Added new field `hostname´ to the SilcClientEntry context.
2601 It holds the hostname of the client. Affected file is
2602 lib/silcclient/idlist.h.
2604 * Irssi SILC Client sets the nicknames in nick@hostn format.
2605 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2606 irssi/src/silc/core/silc-core.c.
2608 The WHOIS printing now also shows both the real nickname and
2609 the formatted nickname so that user knows how to access the
2610 user if there are multiple same nicknames cached. Affected
2611 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2612 printing formatting too to take the hostname now as a separate
2613 argument. The Affected file is
2614 irssi/src/fe-common/silc/modules-formats.[ch].
2616 * Changed the silc_client_get_clients_local to accept the formatted
2617 nickname as argument. It accepts the real nickname too but the
2618 formatted nickname can be used to find the true entry from
2619 multiple entries. Affected file lib/silcclient/silcapi.h and
2620 lib/silcclient/idlist.c.
2622 * Added nickname_format_parse field to the SilcClientParams.
2623 It is a callback function provided by the application to parse
2624 the nickname out of the formatted nickname string. The library
2625 calls it to get the nickname from the formatted string. Since
2626 the application generally knows better the format of the nickname
2627 string it parses it instead of the library, even though library
2628 encodes the formatted string. If the callback function is not
2629 provided then the library will use the string as is. The
2630 affected file is lib/silcclient/silcapi.h.
2632 * All the nickname strings passed to the client library in
2633 commands are now expected to be formatted nickname strings.
2634 If the command does not support the formatted nickname string
2635 it will assume that the sent string is the actual nickname.
2636 Affected file lib/silcclient/command.c.
2638 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2640 * Added public key authentication support to OPER and SILCOPER
2641 commands in the client library. Affected file is
2642 lib/silcclient/command.c.
2644 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2646 * Changed the get_auth_methdod client operation to be asynchronous.
2647 It can be async if the application resolves the authentication
2648 method from the server during the negotiation. Added new
2649 SilcGetAuthMeth completion callback that the application will
2650 call after resolving the authentication method.
2652 Added function silc_client_request_authentication_method that
2653 the application can use to resolve the authentication method
2654 from the server. Added also SilcConnectionAuthRequest callback
2655 that the library will call after the server has replied. The
2656 application can call this function if it does not know the
2657 current authentication method.
2659 Affected files are lib/silcclient/client.c and
2660 lib/silcclient/silcapi.h.
2662 * The Irssi SILC client now automatically resolves the authentication
2663 method incase any configuration information is not present (and
2664 currently there never is). The affected file is
2665 irssi/src/silc/core/client_ops.c.
2667 * Fixed public key authentication from the client library.
2668 Affected file lib/silcclient/protocol.c. Changed also the
2669 protocol specification about the public key authentication in
2670 the connection authentication protocol. The actual data to be
2671 signed is now computed with a hash function before signing.
2673 * Fixed the public key authentication from the server as well.
2674 Affected file silcd/protocol.c.
2676 * Removed the mlock()'s from the memory allocation routines.
2677 Affected file lib/silcutil/silcmemory.c. The ./configure does
2678 not check anymore for the mlock(). Affected file is
2681 * Fixed USERS command in server to allow the execution of the
2682 command for private and secret channels if the client sending
2683 the command is on the channel. Affected file silcd/command.c.
2685 * Fixed silc_client_get_clients_local to return the clients
2686 count correctly. It could return wrong value. Affected file
2687 lib/silcclient/idlist.c.
2689 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2691 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2692 types. The assembler optimizations seemed not to like 64-bit
2693 data types. The assmebler optimizations thus are now enabled
2694 also for BSD systems as opposed to only enable them for Linux.
2696 * Do not check for threads at all on BSD systems. Affected
2697 file configure.in.pre.
2699 * Removed -n and -h options from the Irssi SILC Client since
2700 they are not used in silc.
2702 * Fixed the prime generation to assure that the first digit
2703 of the generated random number is not zero since our conversion
2704 routines does not like number strings that starts with zero
2705 digit. If zero digit is seen the random number is regenerated.
2706 This caused some corrupted RSA keys when the zero first digit
2707 was met. Affected file lib/silcmath/silcprimegen.c.
2709 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2711 * Fixed WIN32 configuration in the ./configure script.
2712 Fixed to include xti.h on environments that has it.
2713 Patches by Carsten Ilchmann and andrew.
2715 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2717 * Changed the silc_id_create_client_id to be collision
2718 resistant. It is now assured that there cannot be created
2719 two same client ID's. I suspect that some weird bugs in
2720 the server were actually caused by duplicate Client IDs.
2721 Affected file silcd/serverid.[ch]. A router receiving
2722 new ID now also assures and informs the sending server
2723 if the ID caused collision.
2725 * Changed the silc_id_create_channel_id to also assure that
2726 there are no collisions.
2728 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2730 * Statement about ignoring the Mutual Authentication flag when
2731 performing rekey with PFS was a bit misleading. It is ignored
2732 if it was set in the initial negotiation, it cannot be even
2733 set in the rekey. Fixed in the ke-auth draft. Started the
2734 new versions of the protocol drafts in the doc/.
2736 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2738 * Fixed a bug in silc_client_command_identify_save when saving
2739 new channel information. The channel name was no duplicated
2740 and caused crash on exit. Affected file is
2741 lib/silcclient/command_reply.c.
2743 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2745 * Fixed the getkey command handling in the server. Send just
2746 empty OK reply to the sender if the key could not be fetched
2747 (but everything else was ok, like the key just was not available).
2748 Changed the public key parameter to optional in the protocol
2749 specs so that empty OK reply can be sent. Affected file
2752 Added a message to Irssi SILC client to tell to user if the
2753 server did not return a public key.
2755 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2757 * Fixed a channel key regeneration bug. It registered new
2758 timeout tasks exponentially until all system resources were
2759 used. Affected file silcd/server.c.
2761 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2763 * Added the SILC Document generator to the scripts/silcdoc.
2764 It can be used to generate the Toolkit Reference Manual out
2765 of the source tree. Internally it will also use the RoboDoc
2766 generator now imported in util/robodoc.
2768 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2770 * Added couple of return's in rekey protocol if error orccurred
2771 during the protocol. The execution must be terminated.
2772 Affected file silcd/protocol.c. Also, terminate the protocol
2773 always with timeout.
2775 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2777 * The client's Client ID was created initally from the wrong
2778 nickname (it could have been in format nick@host) in the
2779 silc_server_new_client. Affected file silcd/packet_receive.c
2781 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2783 * Added some SILC_LOG_ERROR's to various error conditions
2784 if client could not be added to ID cache. Affected files
2785 silcd/packet_receive.c and silcd/server.c.
2787 * When client's sock->user_data is freed, NULL also the
2788 client->router and client->connection pointers. Added check
2789 for these pointers being NULL to various places around the
2790 code. Affected file silcd/server.c.
2792 * Added client->data.registered == TRUE checks to various
2793 places around the code to assure that unregistered client's
2794 are not handled when it is not allowed. Affected file
2797 * Added `bool registered' fields to all
2798 silc_idlist_[server|client]_get_* routines to indicate whether
2799 the fetched client needs to be registered or not. Affected
2800 file silcd/idlist.[ch].
2802 * Add your own entry as registered to the ID cache in the
2803 server. Affected file server.c.
2805 * Fixed a bug in silc_server_new_server. The SilcServer was
2806 set as the new server's context instead of SilcServerEntry.
2807 This naturally caused some weird bugs.
2809 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2811 * Do not delete the channel rekey task when adding it
2812 for in silc_server_create_channel_key.
2814 * Changed the silc_server_create_channel_key to return
2815 TRUE or FALSE to indicate the success of the channel key
2818 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2820 * Fixed MSVC++ project files and added missing files to
2821 Makefiles under win32/.
2823 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2825 * Do not add TCP_NODELAY flag if the operating system
2826 does not have it defined. Affected files are
2827 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2829 * Fixed buffer overflow from Irssi SILC Client. Affected
2830 file irssi/src/fe-common/core/themes.c.
2832 * Fixed double free in client library in the file
2833 lib/silcclient/client.c when disconnecting from server.
2835 * Applied double free patch from cras to Irssi SILC client.
2836 Affected files irssi/src/core/[modules/expandos].c
2838 * Fixed the disconnection handling to Irssi SILC Client.
2839 The application must call silc_client_close_connection
2840 in ops->connect client operation in case of failure of
2841 the connection. Affected file is
2842 irssi/src/silc/core/client_ops.c.
2844 * Do not set sock->protocol to NULL in the function
2845 silc_client_close_connection after executing the protocol's
2846 final callback since the sock might not be valid anymore.
2847 Affected file lib/silcclient/client.c.
2849 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * Do not enable SILC_THREADS if the linking with libpthread
2852 did not happen. Affected file configure.in.pre.
2854 * Added notion to protocol specification that server must
2855 verify the sent authentication payload with CMODE when
2856 setting the channel founder key. Implemented it to the
2857 server. Affected file silcd/command.c.
2859 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2861 * Added _EXTRA_DIST SILC distribution variable to the
2862 distributions file. It is used to conditionally add extra
2863 files or directories to the specific distribution. Affected
2864 files ./prepare, Makefile.am.pre and distributions.
2866 Removed the `_' from the start of the distribution names.
2869 * Added README.WIN32 for instructions to compile the Toolkit
2872 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2874 * Fixed a double free in disconnection in the server. Affected
2875 file is silcd/server.c.
2877 * Fixed the lib/silcske/groups.c to work now also with GMP
2878 MP library. The string conversion did not work when using
2879 specific base and the base is indicated in the string as well.
2881 * Created win32/ directory which now includes MSVC++ specific
2882 stuff so that toolkit (DLLs) may be compiled with MSVC++.
2883 It will appear only in the toolkit distribution
2885 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2887 * Changed the key material distribution function in case when
2888 the hash output is too short. The data is now concatenated
2889 a bit differently than it used to. Made the change to the
2890 SKE protocol specification.
2892 * Added better GMP detection to configure.in.pre. A patch
2895 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2897 * Fixed a minor bug in SKE that might cause some problem on
2898 some platforms. Affected file lib/silcske/silcske.c.
2900 * Added the cookie checking for initiator in the SKE. It checks
2901 that the responder returns the sent cookie unmodified. The
2902 affected file is lib/silcske/silcske.c. Added new SKE
2903 error type INVALID_COOKIE that can be sent during the
2904 negotiation. Fixed some memory leaks as well.
2906 * Added the "invalid cookie" error message to Irssi SILC client's
2909 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2911 * Added `task_max' field to the SilcClientParams to indicate
2912 the maximum tasks the scheduler can handle. If set to zero,
2913 default values are used. Affected file lib/silcclient/silcapi.h.
2915 * Fixed memory leaks in silc_client_close_connection. Affected
2916 file lib/silcclient/client.c.
2918 * Added silc_client_del_client_entry to client library to free
2919 all memory of given client entry. Affected file is
2920 lib/silcclient/idlist.[ch].
2922 * Added new functions silc_client_del_channel and
2923 silc_client_del_server to delete channel and server entries.
2924 Affected file lib/silcclient/[silcapi.h/idlist.c].
2926 * Removed silc_client_del_client_by_id from silcapi.h.
2928 * Fixed the INFO command to return the server's own info
2929 correctly when querying by Server ID. Affected file is
2932 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2934 * Removed the non-blocking settings in WIN32 code in the
2935 silc_sock_[read/write] and added SleepEx instead. Affected
2936 file lib/silcutil/win32/silcwin32sockconn.c. The availability
2937 of input data is now checked with FIONREAD and ioctlsocket.
2939 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2941 * Call silc_schedule_task_del_by_context in the
2942 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
2943 Affected file lib/silccore/silcprotocol.c.
2945 * Call silc_protocol_cancel for active protocols in the
2946 silc_server_close_connection if the funtion
2947 silc_server_free_sock_user_data has not been called.
2948 Affected file silcd/server.c.
2950 * Generic tasks cannot be deleted using the del_by_fd
2951 task deleting function since generic tasks does not match
2952 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
2954 * Added a notion to SILCOPER help file that the SILCOPER works
2955 only on router server, not on normal server.
2957 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2959 * Added for WIN32 support for the new scheduler as well.
2960 Affected file lib/silcutil/win32/silcwin32schedule.c.
2962 * Fixed the SHA1 implementation to work on various platforms.
2964 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2966 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
2967 API. It is part of the scheduler now. Everything else is
2968 as previously but some functions has changed their names.
2969 Checkout the lib/silcutil/silcschedule.h for the interface.
2970 Updated all applications to use the new interface. Affected
2971 files are lib/silcutil/silcschedule.[ch].
2973 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2975 * Found a bug in the SKE implementation. The HASH value,
2976 specified by the protocol, was not computed correctly. The
2977 public key of the responder was not added to the computation
2978 even though it is mandatory. Affected file lib/silcske/silcske.c.
2979 This unfortunately causes incompatibilities with older
2980 clients and servers.
2982 * Added WIN32 specific network init and uninit functions:
2983 silc_net_win32_init and silc_net_win32_uninit to init and uninit
2984 the Winsock2. Affected file lib/silcutil/silcnet.h and
2985 lib/silcutil/win32/silcwin32net.c.
2987 * Set the socket always to nonblocking mode on WIN32 after
2988 reading data or writing data. Affected file is
2989 lib/silcutil/win32/silcwin32sockconn.c.
2991 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2993 * Fixed various compilation problems under WIN32. Affected
2994 files lib/silcutil/win32/silcwin32thread.c and
2995 lib/silcutil/win32/silcwin32schedule.c.
2997 * Removed all _internal.h #includes from public header
2998 files. Internal headers must never be included from
3001 Removed also the lib/silcske/payload_internal.h file.
3003 * All include files that may be needed (public and some others
3004 included by the public headers) by application developers are
3005 now copied to the ./includes directory. It does not copy any
3006 internal headers. Affected file Makefile.defines.pre and all
3007 Makefile.am's under lib/ and subdirs.
3009 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3011 * Do not change the ~/.silc directory's permissions automatically.
3012 Affected file irssi/src/silc/core/clientutil.c.
3014 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3016 * Do not cancel the protocol in silc_server_close_connection
3017 it might cause recursion. Now cancelled in the function
3018 silc_server_free_sock_user_data. Affected file silcd/server.c.
3020 * Fixed the silc_server_remove_clients_by_server to regenerate
3021 the channel keys correctly finally. Added also new function
3022 silc_server_remove_clients_channels to actually do it.
3023 Affected file silcd/server.c.
3025 * Fixed the silc_server_new_channel to not crash by giving
3026 wrong router to the new channel. Affected file is
3027 silcd/packet_receive.c.
3029 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3031 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3032 which is given as argument to the silc_client_alloc now.
3033 It can be used to configure the client and set various parameters
3034 that affect the function of the client.
3036 * The USERS command in server did not check whether the channel
3037 is private or secret. Affected file silcd/command.c.
3039 * Added new argument to the USERS command in protocol specification.
3040 The USERS command now can take the channel name as argument
3041 as well. Added support for this in client and server and
3042 updated the protocol specs.
3044 * Completed the GETKEY command in client. It can be now used
3045 to fetch also servers public key not only some clients.
3046 Affected files lib/silcclient/command[_reply].c.
3048 * Added silc_client_get_server to return server entry by the
3049 server name. Affected files lib/silcclient/silcapi.h and
3052 * Redefined the IDENTIFY command in protocol specification to be
3053 more generic. It now can be used to query information about
3054 any entity in the SILC Network, including clients, servers and
3055 channels. The query may be based either the entity's name
3056 or the ID. Added support for this in both client and server.
3058 Affected files silcd/command.c and lib/silcclient/command.c
3059 and command_reply.c.
3061 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3062 the _from_client and _from_server functions. Affected file
3065 * Added silc_client_get_channel_by_id_resolve to the file
3066 lib/silcclient/silcapi.h to resolve channel information by
3067 its ID. Added also silc_client_get_channel_by_id that
3068 does not resolve it from the server.
3070 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3072 * Added SilcServerEntry context into the client library
3073 to represent one server. The INFO command now allocates
3074 these to save the resolved server info. For now on the
3075 client library will also keep information about servers,
3076 connected and resolved with INFO.
3078 The INFO command now allocates the SilcServerEntry context
3079 and saves the server info there. The COMMAND_REPLY in
3080 the INFO now returns the parameters to application in
3081 same order as defined in the protocol specification.
3083 The entries are cached in the client->server_cache.
3085 * The INFO command is now issued after received the Client ID
3086 from the server. Affected file lib/silcclient/client.c.
3088 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3089 to the application as the mode changer might be server.
3090 It is guaranteed that NULL is not returned anymore to the
3091 application. Affected file lib/silcclient/client_notify.c.
3093 The ID Type is now also passed to the application so that
3094 it can check whether the returned entry is SilcClientEntry
3097 Added new function silc_client_get_server_by_id to return
3098 the server entry by ID. Affected files are the
3099 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3101 * Do not create the channel in the Irssi SILC Client when issuing
3102 the JOIN command but when received the sucessful JOIN command
3103 reply. Otherwise the channel might get created even though we
3104 could not join it. The Affected file is
3105 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3107 * Fixed a channel joining bug in router. The router must also
3108 check the channel modes, invite and ban lists etc. when serving
3109 the JOIN command sent by normal server. Affected file is
3110 silcd/command.c. The router now resolves the client's
3111 information from the server who sent the JOIN command if it
3112 does not know it, and processes the JOIN command only after
3115 * Changed the SilcCommandCb to take new argument; void *context2.
3116 Affected file lib/silccore/silccommand.h
3118 The second argument in the command callbacks in the server now
3119 includes the SilcServerCommandReplyContext if the command was
3120 called as pending command callback from the command reply.
3121 Otherwise it is NULL. When called as pending the status of the
3122 command reply will be checked and if it was erronous the
3123 error will be sent to the original sender of the command.
3124 This way the client always receives the error messages even
3125 though the server was actually the one who received the error
3126 when it resent the command to router, for example. Affected
3127 files silcd/command[_reply].[ch].
3129 * Fixed sending WHOWAS command's error message to client if
3130 the requested client could not be found. It was missing.
3133 * Changed the CMODE and CUMODE commands reply arguments in the
3134 protocol specification. The Channel ID is now sent in both
3135 of the commands to identify the channel. Implemented this
3136 new feature to the client and server. Affected files
3137 lib/silcclient/command_reply.c and silcd/command.c.
3139 * Made better checks for invite and ban lists in the JOIN
3140 command in server. Affected file silcd/command.c.
3142 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3144 * The server now performs the incoming host IP/DNS lookup
3145 using the silc_socket_host_lookup and thus does not block
3146 the server anymore. Affected file silcd/server.c.
3148 * Completed the multi-thread support for SILC Scheduler in
3149 the lib/silcutil/silcschedule.c.
3151 * Fixed the configure.in.pre to detect the pthread correctly
3154 * Fixed a deadlock in silc_task_queue_wakeup in the file
3155 lib/silcutil/silctask.c.
3157 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3159 * Added new function silc_schedule_wakeup that is used in
3160 multi-threaded environment to wakeup the main thread's
3161 schduler. It needs to be used when a thread adds a new task
3162 or removes a task from task queues. After waking up, the
3163 scheduler will detect the task queue changes. If threads
3164 support is not compiled in this function has no effect.
3165 Implemented the wakeup mechanism to both Unix and WIN32
3166 systems. Affected files are lib/silcutil/silcschedule.[ch],
3167 lib/silcutil/unix/silcunixschedule.c and the
3168 lib/silcutil/win32/silcwin32schedule.c.
3170 * Added new function silc_task_queue_wakeup to wakeup the
3171 scheduler by the specified task queue. Affected file
3172 lib/silcutil/silctask.[ch].
3174 * The silc_socket_host_lookup_start now wakes up the scheduler
3175 after adding the timeout task. Affected file is
3176 lib/silcutil/silcsockconn.c.
3178 * The silc_socket_host_lookup is synchronous now if the threads
3179 support is not compiled in. However, the callback is still
3180 called asyncronously through the scheduler, anyway. Affected
3181 file lib/silcutil/silcsockconn.c.
3183 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3185 * Added new function silc_socket_host_lookup to perform
3186 asynchronous IP and FQDN lookups for the socket connection.
3187 Affected files lib/silcutil/silcsockconn.[ch].
3189 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3191 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3192 that may or may not compile the mutex support in.
3194 Changed the silc_mutex_alloc interface. It allocates the
3195 mutex now to the sent pointer and returns TRUE or FALSE.
3197 Affected file lib/silcutil/silcmutex.h.
3199 * Wrote the SILC Task Queue interface to support multi-threads.
3200 Affected file lib/silcutil/silctask.[ch].
3202 * Wrote the SILC Scheduler to support multi-threads. Affected
3203 file lib/silcutil/silcschedule.c.
3205 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3207 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3208 in lib/silcutil/win32/.
3210 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3212 * Defined SILC Mutex API and SILC Thread API and implemented
3213 them for Unix. Affected files are
3214 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3215 lib/silcutil/unix/silcunixmutex.c and
3216 lib/silcutil/unix/silcunixthread.c.
3218 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3220 * Fixed the silc_server_remove_clients_by_server's channel
3221 key re-generation. The hash table handling was incorrect
3222 and would not work with many channels. Affected file is
3225 * Fixed some memory leaks around the server code.
3227 * Rewrote the silc_server_get_users_on_channel to support IPv6
3228 based Client ID's. Affected file silcd/server.c.
3230 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3231 specification. However, a separate document must be written
3232 to define the detailed signing procedure and the payload
3233 associated with the flag. Defined the flag to the
3234 lib/silccore/silcchannel.h as well.
3236 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3238 * Changed the dynamic tables to static size tables in the
3239 lib/silccrypt/silchmac.c.
3241 * Removed GCC dependencies from the code. A patch by cras.
3243 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3245 * Do not show the error "Error receiving packet bla bla"
3246 in server if it really was not an error (-2 means that reading
3247 is pending). Affected file silcd/server.c.
3249 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3251 * Fixed a possible crash in silc_server_remove_clients_by_server
3252 in silcd/server.c. Fixed there also some memory leaks.
3254 * Fixed the silc_idlist_replace_client_id. It could replace
3255 wrong key in the hash table. Affected file silcd/idlist.c.
3257 * Do not check whether there are global users on the channel
3258 if the channel->global_users is FALSE. Affected functions
3259 silc_server_remove_from_one_channel and
3260 silc_server_remove_from_channels in silcd/server.c. Also,
3261 do not check if the removed client is local as we can be
3262 sure that global client was not removed from the channel
3263 and checking for global users is not needed.
3265 * The silc_server_remove_clients_by_server now re-generates
3266 the channel keys correctly for those channels that had
3267 clients removed from them. Affected file silcd/server.c.
3269 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3271 * Found the reason of random crashes in the server. We weren't
3272 ignoring the SIGPIPE signal (which can be sent in write())
3273 and it crashed the server. Affected file silcd/silcd.c.
3275 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3277 * Assure that sock->user_data is not NULL in the function
3278 silc_server_packet_send in silcd/packet_send.c.
3280 * Disconnect the remote connection if it could not be added
3281 to any ID lists in the server. The affected file is
3284 * Check in silc_server_packet_send[_real/dest] that the
3285 socket is not disconnecting and ignore the data if it is.
3286 Affected file silcd/packet_send.c.
3288 * Define inline to __inline on native WIN32 compilation.
3289 Affected file includes/silcwin32.h.
3291 * Added some explicit type casts for inline code since MSVC
3292 require them. Affected files lib/silcutil/silcbuffer.h,
3293 lib/trq/silcdlist.h and lib/trq/silclist.h.
3295 * Print warning in log files from now on if the packet
3296 decryption fails. Affected file silcd/server.c.
3298 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3300 * Changed the `say' client operation's interface to accept
3301 new `type' argument to indicate the type of the message sent
3302 by the library. The application may filter the library's
3303 messages according the type. The affected file is the
3304 lib/silcclient/silcapi.h.
3306 * Added two new functions to lib/silcclient/silcapi.h:
3307 silc_client_del_client and silc_client_del_client_by_id.
3308 Affected file lib/silcclient/idlist.c.
3310 * Moved the clientincludes.h from includes/ to silc/ and
3311 serverincludes.h from includes/ to silcd/.
3313 * The modes for the CMODE and CUMODE are now passed as
3314 uint32 for application with COMMAND_REPLY. The affected
3315 file is lib/silcclient/command_reply.c.
3317 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3319 * /WHOIS without arguments shows client's own information.
3320 Affected file lib/silcclient/command.c.
3322 * Changed PING to not accept any arguments. The specs
3323 says that client can ping only the connected server so
3324 requiring an argument is not needed. Affected file is
3325 lib/silcclient/command.c.
3327 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3329 * Fixed a fatal bug in private message sending and reception
3330 encryption and decryption when using private message keys.
3331 The implementation was incorrect and did not follow the
3332 specification. It causd that some of the message were
3333 lost since it did not use the sending and receiving keys
3334 as the protocol suggests. This has been fixed and will cause
3335 incompatibilities with older clients when sending private
3336 message encrypted with private message keys. Affected files
3337 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3338 and various other in Irssi SILC Client.
3340 Added `responder' boolean argument to the functions
3341 silc_client_add_private_message_key[_ske] to indicate when
3342 the key is added as responder or initiator of the key
3345 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3347 * Removed the silc_ske_check_version function and created
3348 a SilcSKECheckVersion callback. Added also a function
3349 silc_ske_set_callbacks that is now used to set all SKE
3350 callbacks. The callback functions are not given to
3351 the SKE functions anymore, but this function is used to
3354 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3356 * Added `silc_version' argument to the silc_client_alloc
3357 to define the version of the application for the library.
3358 The library will use the version string to compare it
3359 against the remote host's (usually a server) version
3360 string. Affected file lib/silcclient/silcapi.h
3362 * Added the KE protocol context to Key Agreement context
3363 in client library so that we can abort the SKE if it
3364 is in process when we get timeout. Affected file is
3365 lib/silcclient/client_keyagr.c.
3367 * Do not resolve the client ID forever if it returns in the
3368 first time that such client does not exist. This was done
3369 for example with private message. Affected file is
3370 lib/silcclient/client_prvmsg.c.
3372 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3374 * Do not add regex.h for WIN32. The affected file
3375 includes/silcincludes.h.
3377 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3378 not work yet 100%. It generates the DLL's automatically
3379 when compiling with --with-win32 under cygwin.
3381 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3383 * lib/contrib/regex.c is not compiled on WIN32.
3385 * Added silc_net_get_socket_opt function to the
3386 lib/silcutil/silcnet.h.
3388 * Added includes/silcwin32.h for WIN32 specific includes
3391 * Do not use ptime structure or any of the posix process
3392 functions on WIN32 in lib/silccrypt/silrng.c.
3394 * Added silc_gettimeofday to provide generic function
3395 for struct timeval on all platforms. Added the function
3396 to lib/silcutil/silcutil.h.
3398 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3400 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3401 library as they clearly belong there. As a plus side we
3402 can make the actual socket connection routines platform
3405 Added also new generic function silc_socket_read and
3406 silc_socket_write (that used to be silc_packet_[read/write].
3407 The implementation of these are platform specific.
3409 * Added WIN32 specific routines of silc_socket_[read/write]
3410 to lib/silcutil/win32/silcwin32sockconn.c.
3412 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3414 * Added preliminary support for native WIN32 compilation under
3415 cygwin (using the -mno-cygwin option for GCC) to the
3416 ./configure.in.pre. The --with-win32 now prepares the
3417 compilation for native WIN32.
3419 * Rewrote the SILC Scheduler interface in the file
3420 lib/silcutil/silcschedule.h. The scheduler is now context
3421 based and does not have anymore any global static scheduler.
3422 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3423 and created lib/silcutil/win32 directory for WIN32 based
3426 * Added Unix specific network routines to the
3427 lib/silcutil/unix/silcunixnet.c and the old
3428 lib/silcutil/silcnet.c includes now only generic routines.
3430 Added WIN32 specific network routines to the
3431 lib/silcutil/win32/silcwin32net.c.
3433 * Added Unix specific utility functions from the
3434 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3436 * Added WIN32 SILC Scheduler to the file
3437 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3440 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3442 * Do not handle JOIN notify in the server if the target client
3443 is not registered (idata->registered == FALSE). The affected
3444 file is silcd/packet_receive.c.
3446 * Update the nickrec->founder in event_cumode in the Irssi SILC
3447 client. Affected file irssi/src/silc/core/silc-channels.c.
3449 * Fixed the CUMODE_CHANGE notify handling in the server when
3450 server and router are announcing their clients on channels.
3451 Now the mode changes are saved and notified correctly. The
3452 affected file is /silcd/packet_receive.c.
3454 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3455 They really did not replace the cache entry in the ID Cache.
3456 Now they do that. Affected file silcd/idlist.c.
3458 * Fixed the KICK notify handling in the Irssi SILC client to
3459 update the channel records so that the kicked client does not
3460 appear to be on the channel. The affected file is
3461 irssi/src/silc/core/silc-channels.c.
3463 * Always update the conn->current_channel when executing command
3464 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3466 * Fixed the KILL notify handling in Irssi SILC client to remove
3467 the killed client on all channels.
3469 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Fixed the silc_parse_command_line to remove extra spaces
3472 from the start and end of the arguments. Affected file is
3473 lib/silcutil/silcutil.c.
3475 * Cancel and free any active protocol in the function
3476 silc_server_close_connection. Affected file silcd/server.c.
3478 * Cancel and free any active protocol in the function
3479 silc_client_close_connction. Affected file is
3480 lib/silcclient/client.c.
3482 * Do not execute the KILL command for clients that are in
3483 history (ie. they are not in the network). Affected file is
3486 * Fixed KILL notify handling, client does not crash anymore.
3487 Affected file irssi/src/silc/core/silc-channels.c.
3489 * Reduced the default packet buffer size from 2048 to 1024 in
3490 lib/silccore/silcpacket.c.
3492 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3493 counter to the SKE context that is incresed when the SKE library
3494 performs async operation outside the library. If the outside
3495 process frees the SKE context and FREED status will be set
3496 and the library will detect after the sync operation that the
3497 libary is freed. The affected files are
3498 lib/silcske/silcske[_status].[ch].
3500 * Resolve the client entry information in the function
3501 silc_client_channel_message to assure that NULL pointer is not
3502 passed as client entry to the application. */
3504 * Fixed the task timeout calculation to assure that there is
3505 never negative timeouts. The affected file is
3506 lib/silcutil/silcschedule.c.
3508 * Fixed the channel user mode notification sending in server.
3509 It was sent point-to-point to the router (or to server by router)
3510 but it needs to be destined to a channel. The routines now
3511 supports sending the channel user mode notifys to the channels
3512 when announcing clients and channels. Affected files are
3513 silcd/server.c and silcd/packet_receive.c.
3515 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3516 It did not actually replace the old channel entry in the cache.
3517 Affected file lib/silcclient/client_notify.c.
3519 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3521 * Fixed a possible crash in silc_packet_send_prepare. It now
3522 assures always that there is enough space in the buffer and
3523 at the tail area of the buffer (for MAC).
3525 Fixed the inbound buffer reallocation in silc_packet_read.
3526 It was old code and did not handle the reallocation correctly.
3529 The affected file is lib/silccore/silcpacket.c.
3531 * Fixed buffer overflow in silc_parse_nickname in the file
3532 lib/silcutil/silcutil.c.
3534 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3536 * make install generates new server keys only if there is not
3539 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3541 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3542 Added check that if the NOREPLY is set then we will not send
3543 the away message. This avoids infinite loop of away messages
3544 if both clients are away. The affected file is
3545 lib/silcclient/client_prvmsg.c.
3547 * Fixed client crash if /NICK was given without arguments.
3548 Affected file lib/silcclient/command.c.
3550 * Server does not send the invite list in INVITE command back
3551 to the client if the list was not altered. Added this notion
3552 to the protocol spec as well. Affected file silcd/command.c.
3554 Fixed possible crash in INVITE command by checking the
3555 value of silc_server_get_client_route command.
3557 * Fixed the INVITE notify type handling. The arguments are now
3558 taken in correct order and client does not crash. The affected
3559 file is irssi/src/silc/core/silc-channels.c.
3561 Removed the "Inviting xxx to channel" message from the
3562 client library away and let the application handle it.
3563 Affected file lib/silcclient/command.c. Added that message
3564 to Irssi SILC client's message formats.
3566 * Fixed CMODE command crash in client. It now checks the
3567 amount of arguments correctly and does not crash. The affected
3568 file is lib/silcclient/command.c.
3570 * Do not create new channel automatically in silc_channels_join
3571 but check whether the channel by that name already exists.
3572 Affected file irssi/silc/core/silc-channels.c.
3574 * Do not send the SERVER_SIGNOFF to router if the disconnected
3575 entity was the router. Affected file silcd/server.c.
3577 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3578 SILC client as it was missing from there.
3580 Added the handling of the KICK notify to the Irssi SILC client
3581 as it was missing. Added "you have been kicked" message to
3582 Irssi SILC client's message modules formats.
3584 Added the handing of the KILL notify to the Irssi SILC client
3585 as it was missing. Added the kill message module formats
3588 The affected file is irssi/src/silc/core/silc-channels.c.
3590 * The router did not save the channel mode the server announced.
3591 Affected file silcd/packet_receive.c.
3593 * Fixed a possible crash in INFO command in server. If the
3594 server did not provide the server info it crashed. Affected
3595 file silcd/command.c.
3597 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3599 * Fixed the GETKEY command in the server to check also the
3600 global list. Otherwise the GETKEY would not work correctly
3601 in normal SILC server. Affected file silcd/command.c.
3603 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3605 * Fixed GETKEY crash, it crashed if the command did not succseed.
3607 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3609 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3610 is now real and not just an macro interface to GMP.
3612 Removed the entire GMP from the source tree and imported new
3613 NSS MPI library instead. Reason for removing GMP is that it is
3614 extremely large and compiles extremely slow. The NSS MPI
3615 is only a few files and compiles in less than 10 seconds.
3616 The speed is also about the same as GMP. The MPI is imported
3617 to lib/silcmath/mpi.
3619 If the system has GMP installed we will still use the GMP.
3620 If it is not then the NSS MPI will be compiled.
3622 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3624 * Merged a long nickname (127 characters long) crash bugfix from
3625 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3627 * Merged a freed memory reference bugfix from Irssi CVS tree.
3628 Affected file irssi/src/core/commands.c.
3630 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3632 * Added the server's public key sving and verification to the
3633 server when performing the SKE. This was missing and the
3634 remote server's (or router's) public key was accepted without
3635 checking whether we have it previously or trust it at all.
3636 Affected file silcd/protocol.c.
3638 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3640 * Check in the silc_server_timeout_remote if protocol is active
3641 and make sure that the protocol's final callback is called so
3642 that all memory if freed. Affected file silcd/server.c.
3644 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3646 * silc_server_whois_send_reply crashed the server if the nickname
3647 was 127 characters long. Affected file silcd/command.c.
3649 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3651 * Added sanity check to the silc_server_new_client. If the hostname
3652 is provided inside username then check that the provided hostname
3653 really is the same as the resolved one. If the hostname was not
3654 resolved then check it from the public key. Affected file is
3655 silcd/packet_receive.c.
3657 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3658 if the server disconnected us and the connection is not valid
3659 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3661 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3662 the library to the lib/silcutil/silcutil.[ch].
3664 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3666 * Close log file after open. Affected file
3667 lib/silcutil/silclog.c.
3669 * Check whether sock == NULL in silc_client_send_packet and return
3670 if it is. Affected file lib/silcclient/silcclient.c.
3672 * Check rec->entry == NULL in the Irssi SILC Client before
3673 sending the channel message. Affecte file is
3674 irssi/src/silc/core/silc-servers.c.
3676 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3678 * Merged a splitted window bugfix from Irssi CVS tree. The
3679 affected file is irssi/src/fe-text/textbuffer-view.c.
3681 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3682 It did not print nickname.
3684 * Improved the distributions system a bit.
3686 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3688 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3689 irssi/src/fe-text/gui-window.c.
3691 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3692 to in-active server. The affected file is
3693 irssi/src/silc/core/client_ops.c.
3695 * Resolve the client in USERS command reply if the entry does
3696 not have username resolved. The affected file is
3697 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3698 command to WHOIS command to really resolve stuff. The USERS
3699 is not used any more in any critical section so WHOIS can
3700 be used even though it might be slower than IDENTIFY.
3702 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3705 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3707 * Changed the protocol API a bit more consistent in the
3708 lib/silccore/silcprotocol.[ch].
3710 * Changed the following headers to ROBODoc format:
3712 lib/silccore/silcpayload.h
3713 lib/silccore/silcprotocol.h
3714 lib/silccore/silcsockconn.h
3716 All core library headers are now formatted.
3718 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3720 * Fixed a bug in Irssi SILC client; do not show that you are
3721 server/router operator if you really are not. Affected file is
3722 irssi/src/silc/core/client_ops.c.
3724 * Renamed silc_command_free_payload to silc_command_payload_free.
3725 Affected file lib/silccore/silccommand.h
3727 * Added silcmath.h to include the prototoypes of various routines
3728 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3731 * Changed the following headers to ROBODoc format:
3733 lib/silccore/silcchannel.h
3734 lib/silccore/silccommand.h
3735 lib/silccore/silcid.h
3736 lib/silccore/silcidcache.h
3737 lib/silccore/silcmode.h
3738 lib/silccore/silcnotify.h
3739 lib/silccore/silcpacket.h
3740 lib/silcmath/silcmath.h
3742 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3744 * Added checking to the server code not to start the server if
3745 ciphers and stuff are not configured properly. Affected files
3746 silcd/serverconfig.[h] and silcd/server.c.
3748 * Changed the layout of the header files of the public interfaces
3749 in the SILC libraries. The new layout supports ROBODoc
3750 documentation tool (and some others) so that it is easy to create
3751 a library reference manual. All the other headers and source
3752 code must still follow the CodingStyle document. Also source
3753 code must not include these ROBODoc stuffs, only the headers.
3754 Furthermore, all public interface headers must now be named
3755 by using `silc' prefix, example: silcapi.h, silccipher.h.
3756 Some files were renamed due to this. All the other headers
3757 must not be used as public interfaces. I will update the
3758 CodingStyle document later. Changed following headers, so far:
3760 lib/silcclient/silcapi.h
3761 lib/silccore/silcauth.h
3762 lib/silccore/silcprivate.h
3763 lib/silccrypt/silcdh.h
3765 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3769 * Removed silc_client_packet_send_flush from the client library
3770 as it is not needed. Affected file lib/silcclient/client.[ch].
3772 * Added printing of message of unresolved authentication method
3773 to the Irssi SILC client. Added it to the module formats.
3774 Removed the same message from the client library.
3776 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3778 * Added new distribution feature, DISTLABEL. Every distribution
3779 can define own preprocessor label that can be used in the
3780 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3781 file distributions, acconfig.h.pre and prepare.
3783 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3785 * Added Makefile.defines_int to include the actual definitions
3786 for Makefile.defines.in. Tested the new distribution system,
3787 created distributions and tested installation.
3789 * Added AWAY message printing to the Irssi SILC client. Added
3790 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3792 * Added SCONNECT command to call the SILC's CONNECT command.
3793 Cannot use CONNECT directly since Irssi uses that internally.
3794 Affected file irssi/src/silc/core/silc-servers.c.
3796 Added ACTION local command. It is same as ME command but takes
3797 the channel as mandatory argument.
3799 Rewrote some of the Irssi's help files to suite for SILC
3802 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3804 * Added Makefile.defines[.in] that should for now on be included
3805 in all Makefile.am file in the source tree. That file includes
3806 all common compilation definitions for SILC source tree.
3808 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3810 * Minor changes to the ./prepare script to change the package
3811 name according the distribution name to the configure.in.
3813 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3815 * Created new distribution system. Added file `distributions'
3816 that defines all the distributions that can be created out of
3817 the SILC source tree. The ./prepare script now reads that
3818 file to determine how to prepare the distributions. The
3819 first argument to the ./prepare is the name of the distribution
3820 and second is the version of the distribution. If given
3821 without arguments it creates the default (toolkit) distribution
3822 with the default version (defined in ./prepare).
3824 All Makefile.am files that are subject to the distributions
3825 are now named as Makefile.am.pre. These are ./Makefile.am
3826 and lib/Makefile.am. Others may be changed later.
3828 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3830 * Added invite list, ban list, some key management and connection
3831 error message printing to module formats in the Irssi SILC client.
3833 * Added new silc_client_set_away_message to set the away message
3834 that is back to the person who sent private message. The
3835 affected file lib/silcclient/silcapi.h and the
3836 lib/silcclient/client_prvmsg.c.
3838 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3840 * Fixed the private message sending in the Irssi SILC client,
3841 added local command KEY to the Irssi SILC client.
3843 Added key management and key agreement message formats to the
3844 irssi/src/fe-common/silc/module-formats.[ch].
3846 Added USERS (alias WHO) printing, server/router operator
3847 indication and LIST command printing to the module formats.
3849 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3851 * Fixed channel joining notify handling, cumode notify handling
3852 from Irssi SILC client.
3854 * Added SILC specific module-formats to the Irssi SILC client so
3855 that SILC specific message hilighting, colors etc is possible.
3856 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3858 Added channel mode, channel user mode, actions, notices,
3859 whois and whowas printing to the the module-formats.c.
3861 * Fixed a bug in channel deletion in the server. The channel
3862 is not left to the cache even if the channel founder auth mode
3863 is set when there are no users anymore on the channel. Affected
3864 file silcd/server.c.
3866 * The silc_net_localhost now resolves the entire hostname including
3867 the domain name. Affected file lib/silcutil/silcnet.c.
3869 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3871 * Changed the ask_passphrase client operation to be ascynchronous.
3872 It has now a completion callback and a context that the
3873 application must call after it has got the passphrase from
3874 the user. Affected files lib/silcclient/silcapi.h,
3875 lib/silcclient/protocol.c, lib/silcclient/command.c and
3878 Added SilcAskPassphrase callback that the application calls
3879 to deliver the passphrase to the library.
3881 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
3882 The public key verification and especially a certificate
3883 verification is asynchronous procedure.
3885 Added new SILC_SKE_STATUS_PENDING status to indicate the
3886 request is pending and a callback will be called to finalize
3889 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
3890 indicate that remote end did not send its public key (or
3891 certificate), even though we require it. Added check for this
3892 condition in the SKE. This was a security bug, now fixed.
3894 Defined new SilcSKEVerifyCbCompletion callback that is called
3895 when the verification process is completed.
3897 The affected files lib/silcske/silcske_status.h and
3898 lib/silcske/silcske.[ch].
3900 * Changed the verify_public_key client operation to be async
3901 as well. Defined SilcVerifyPublicKey callback that is used to
3902 indicate the success of the public key verification process.
3904 Changed the server and client to use the new async client
3907 * Changed the Irssi SILC client's internal scheduler to be called
3908 twice as many times as it used to be. As a result the client
3909 should be a bit faster now. Affected file is
3910 irssi/src/silc/core/silc-core.c.
3912 * Added support to Irssi SILC client of asynchronous public key
3913 verification and passphrase inquiry. Affected file is
3914 irssi/src/silc/core/silc-core.c.
3916 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Do not say "You have left channel %s" in client library.
3919 Moved it to the application. Affected files are
3920 lib/silcclient/command.c and silc/client_ops.c.
3922 * Fixed silc_client_get_clients. Command context was not
3923 duplicated and was freed memory in the callback. Affected
3924 file lib/silcclient/idlist.c.
3926 * Do not say "you are now talking..." on JOIN command in the
3927 client library. The appliation must handle it.
3929 * Do not say ".. changed topic to" in command reply in the
3930 client libary. The application must handle it.
3932 * Fixed TOPIC command sending in the client library.
3934 * Fixed a memory leak in silc_client_command_free in the file
3935 lib/silcclient/command.c.
3937 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3939 * Imported a modified version of Irssi client to the source tree.
3940 The Irssi will be used to create a new client called
3941 Irssi SILC. Imported to irssi/.
3943 Added silc_core_init_finish function to the Irssi. Affected
3944 file irssi/configure.in.
3946 A lot changes in the Makefile.ams around the irssi tree.
3948 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3950 * Do not rehash if the new size is same as the old size of the
3951 hash table, in the silc_hash_table_rehash*. The affected file
3952 lib/silcutil/silchashtable.c.
3954 * Replaced hash_table_del_by_context calls from the server
3955 (when channel->user_list and client->channels) to the
3956 hash_table_del as it is sufficient and faster.
3958 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3960 * Added silc_hash_table_list, silc_hash_table_get and the
3961 SilcHashTableList structure to provide an alternative way to
3962 traverse the hash table. The affected files are
3963 lib/silcutil/silchashtable.[ch].
3965 * Changed the server's idlist routines to use the hash table
3966 routines to optimize the code.
3968 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Replaced the client entry's `channel' list and channel entry's
3971 `user_list' list to hash tables for optimized lookup. Changed
3972 the code to use the hash table interface around the code.
3973 Affected file lib/silcd/idlist.[ch].
3975 * Added `auto_rehash' boolean argument to the function
3976 silc_hash_table_alloc to indicate whether the hash table should
3977 auto-rehash when it thinks is appropriate time. It will
3978 increase the hash table size if the there is twice as much
3979 entries in the table than the size of the table, and will
3980 decrease the size if there are twice as less entries than
3981 the size of the table.
3983 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3985 * Fixed silc_xxx_get_supported to not crash at some circumstances.
3987 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3989 * silc_idcache_purge_by_context deletes the entry now by context
3990 as it is supposed to do. Affected file lib/silccore/idcache.c.
3992 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
3993 client is not anymore valid (WHOWAS givens the info) and not
3994 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
3996 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3998 * Removed the `data' and `data_len' arguments from the ID Cache
3999 interfaces and added `name' argument. ID Cache does not handle
4000 anymore the binary data only a names associated with given ID.
4002 * When hashing a Client ID with silc_hash_id the entire ID is
4003 not hashed anymore, instead only the hash of the Client ID is
4004 hashed. This way we can access the Client ID from the cache
4005 with Client ID but with the hash of the ID (which is a hash of
4006 the nickname) as well without any difference in performance.
4008 Added also silc_idcache_find_by_id_one_ext to do one on one
4009 searching when we have the actual ID. Added also function
4010 silc_hash_client_id_compare. The affected files are
4011 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4013 * When hashing the name associated with a ID it is always done
4014 in lowercase. This way we can access the cache without worrying
4015 about case-sensitivity, even though, for example nicknames are
4018 * Fixed a bug in server with channel message sending. It put
4019 wrong ID type as destination ID. The affected file
4020 silcd/packet_send.c.
4022 * silc_idcache_del_by_context now deletes from all hash tables
4023 by context. Affected file lib/silccore/idcache.c.
4025 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4027 * Changed the client library to use the new ID Cache interface.
4028 Changes around the source tree.
4030 * Added silc_hash_table_rehash_ext to rehash with specific
4031 hash function. Affected file lib/silcutil/silchashtable.[ch].
4033 * Added silc_hash_string_compare to compare two strings in the
4034 hash table. Affected file lib/silcutil/silcutil.[ch].
4036 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4038 * Added new function silc_idcache_del_by_context into the
4039 lib/silccore/idcache.[ch].
4041 * Changed the server's ID list routines to use the new ID Cache
4042 interface. Changes around the source tree.
4044 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4046 * Added silc_hash_table_del[_by_context]_ext functions in to the
4047 lib/silcutil/silchashtable.[ch].
4049 Removed silc_hash_table_find_all* routines and added new
4050 silc_hash_table_find_foreach to replace them.
4052 Added silc_hash_table_replace_ext function as extended
4053 replacing function. Separated the simple hash table interface
4054 from the extended hash table interface in the file
4055 lib/silcutil/silchashtable.h.
4057 * Fixed minor bugs and changed it to use some of the new
4058 hash table functions in lib/silccore/idcache.c
4060 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4062 * Added new function silc_hash_table_find_all to return all keys
4063 in the hash table by the specified key. As the hash table is
4064 collision resistant it also makes it possible to have several
4065 duplicate keys in the hash table. This function may be used to
4066 find all of the keys from the hash.
4068 Added user_context arguments to the SilcHashFunction,
4069 SilcHashCompare and SilcHashDestructor to deliver user specified
4072 Added new fuctions silc_hash_table_find[_all]_ext to do
4073 extended lookup with specified hash and compare functions and
4074 specified user contexts.
4076 Added new function silc_hash_table_add_ext to add the key
4077 with specified hash function and user context.
4079 Added new function silc_hash_table_foreach to traverse all
4080 entrys in the hash table. Added SilcHashForeach callback
4083 Added new function silc_hash_table_del_by_context to delete
4084 the entry only if the context associated with the key matches.
4086 Affected files are lib/silcutil/silchashtable.[ch].
4088 * Removed silc_hash_[server/client/channel]_id and added just
4089 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4090 silc_hash_id_compare to compare two ID's using as the hash table
4091 comparison function. Added also silc_hash_data to hash
4092 binary data and silc_hash_data_compare to compare it.
4094 * Removed silc_idlist_find_client_by_hash as it is not needed
4095 anymore. Affected file silcd/idlist.[ch].
4097 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4098 to use internally the SilcHashTable. The new ID Cache is a lot
4099 faster than the old one. Some of the ID Cache interface was also
4100 rewritten and obsolete and stupid functions were removed.
4102 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4104 * Added entry_count field to the SilcHashTable to keep the number
4105 of the entries in the table. Implemented the function
4106 silc_hash_table_rehash. Added new function
4107 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4109 Fixed a minor bug in silc_hash_table_free.
4111 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4112 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4113 into the lib/silcutil/silcutil.[ch].
4115 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4117 * Implemented a collision resistant hash table into the
4118 lib/silcutil/silchashtable[ch]. See the header and the source
4119 for the SilcHashTable API.
4121 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4123 * Merged dotconf version 1.0.2 into lib/dotconf.
4125 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4127 * Do not compile anything in lib/silcsim/* if the SIM support
4128 is not enabled. The tree should now compile without problems
4131 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4133 * Compiled the SILC under cygwin. Compiled and tested briefly
4134 without problems. More tests needed. The SIMs didn't compile
4137 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4139 * Fixed possible crash in silc_get_username in the
4140 lib/silcutil/silcutil.c.
4142 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4144 * Fixed a va_arg in silc/client_ops.c.
4146 * Oops, RC5 routines were named AES and caused some problems
4147 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4149 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4151 * Added new SilcIDIP structure into the lib/silccore/id.h and
4152 replaced the old `ip' fields from all SILC ID's to that type.
4153 This is a step towards IPv6 support.
4155 The silc_id_get_len takes now the ID as an extra argument.
4156 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4157 both IPv4 and IPv6 based ID's.
4159 The affected files are lib/silccore/id.[ch] and other files
4160 around the tree using these routines.
4162 * Removed the ID length arguments in server from various
4163 silc_server_send_notify_* routines -> they are not needed
4166 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4168 * Fixed memory leak in silc_encode_pem_file in the file
4169 lib/silcutil/silcutil.c.
4171 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4173 * Check minor version as well in the SKE. Affected files are
4174 silcd/protocol.c and lib/silcclient/protocol.c.
4176 * Added --identifier option to the server so that an identifier
4177 can be when creating the public key for the server. Affected
4178 file is silcd/silcd.c.
4180 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4181 lib/silccrypt/silcpkcs.c.
4183 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4185 * Register default ciphers and stuff when using -C option with
4186 the server. Affected file sildc/silcd.c.
4188 * Put back the servers public key filename format, it is better
4189 than the new one. For now, the client keys are saved with the
4190 new filename format. The affected file silc/client_ops.c.
4192 * Implemented the Cipher API for the rest of the ciphers that
4193 did not implement it or implemented it the wrong way.
4195 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4197 * Register default ciphers and stuff when using the -S option
4198 in the client. Affected file silc/silc.c. Same also when
4199 creating new key pair with -C option.
4201 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4203 * Fixed the silc_verify_public_key client operation function to
4204 save the public keys differently. The fingerprint is now
4205 used as filename and not the hostname. This way also the
4206 client keys are saved uniquely and not with hostnames. The
4207 affected file is silc/client_ops.c.
4209 * Trimmed the silc_hash_fingerprint function to remove extra
4210 whitespaces from the end of the fingerprint. The affected
4211 file is lib/silccrypt/silchash.c.
4215 * Added silc_cipher_register_default function to register all
4216 default ciphers. It can be used when configuration files
4217 does not exist and the application does not want any specific
4218 ciphers in any specific order.
4220 The SilcDList is now used as silc_cipher_list dynamically
4221 allocated cipher list. Removed the static list all together
4222 and now all ciphers must be allocated to the dynamic list.
4223 The silc_cipher_alloc routine was changed to check only the
4226 All silc_cipher_* routines that used to return int returns
4229 The affected files lib/silccrypt/silccrypt.[ch].
4231 * The same thing was done to silc_hash_* as for silc_cipher_*
4232 routines. Affected files lib/silccrypt/silchash.[ch].
4234 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4235 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4236 Added also silc_pkcs_[un]register[_default] functions.
4237 Removed the data_context from the PKCS API.
4239 * Added silc_hmac_register_default function to register default
4240 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4241 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4242 to unregister all hmacs at once.
4244 * Register the default ciphers, hash functions, PKCSs and HMACs
4245 if client's configuration file does not exist. The affected
4248 * The client did not load the hash functions from the SIM
4249 modules at all. Added support for this. Affected file is
4250 silc/clientconfig.c.
4252 * When decoding public key with silc_pkcs_public_key_decode, check
4253 the supported algorithm only if PKCS are registered. Affected
4254 file lib/silccrypt/silcpkcs.c. The same was done with the
4255 silc_pkcs_private_key_decode.
4257 * Fixed the SILC List routines to keep the list always in order.
4258 It used to change the list's order when traversing the list but
4259 not it preserves the order. Affected file lib/trq/silclist.h.
4261 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Added the client library to use the SilcSocketConnection's
4264 reference counter (by silc_socket_dup) to prevent the bug that
4265 the socket object may be freed underneath async operation.
4267 * The name resolv library checking fixes in the configure.in.pre.
4270 * Created new version of the protocol drafts for future
4271 development. The -03 drafts are the ones that will be changed
4272 in the trunk now and the -02 will remain as they are.
4274 * Send list of CUMODE notifys to the router when announcing
4275 the channel users to the router. Affected file silcd/server.c.
4276 If the router receiving channel founder CUMODE for a channel
4277 that already has channel founder it will send CUMODE notify
4278 to the sender to remove the channel founder rights from the
4279 announced client. Affected file silcd/packet_receive.c.
4281 * The CUMODE notify may now use Server ID as well as the entity
4282 who changes the mode. Updated protocool specs.
4284 * Updated INSTALL and README files.
4286 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4288 * New web pages in the http://silc.pspt.fi. The pages was
4293 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4295 * Implemented the [DenyConnectin] config section in the server.
4296 Added silc_server_config_denied_conn to check whether incoming
4297 connection is denied. Affected file silcd/serverconfig.[ch].
4299 * Do not check the ports when checking the incoming configuration
4300 data if the port is 0, meaning any. Affected file is
4301 silcd/serverconfig.c.
4303 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4305 * Fixed buffer overflow in silc_string_compare in the file
4306 lib/silcutil/silcutil.c.
4308 * Fixed double free in silc_server_command_leave in the file
4311 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4313 * Fixed the version checking in the server. Affected file is
4316 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4318 * Fixed the configuration data fetching when accepting new
4319 connections in the server. Affected file silcd/server.c.
4321 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4323 * Added `sender_entry' argument to the function
4324 silc_server_packet_relay_to_channel so that we can check
4325 whether some destination actually belongs to the same route
4326 the sender belongs (ie, we must not resend the packet to the
4327 sender). Affected file silcd/packet_send.[ch].
4329 * Added `servername' field to the SilcClientEntry in the server
4330 to hold the name of the server where client is from. Affected
4331 file is silcd/idlist.h.
4333 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4335 * Moved the channel message encrypting in the router betwen
4336 router connections from silc_server_channel_message to the
4337 silc_server_packet_relay_to_channel since we want to check
4338 whether we have anybody channel before encrypting anything.
4339 Affected files silcd/packet_[receive/send].c.
4341 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Fixed the [AdminConnection] server config section to support
4344 multiple entries. Affected file silcd/serverconfig.c.
4346 * Added support into the server to check the validity of the
4347 incoming connection before executing any KE or authentication
4350 * The connection configuration is now saved to the KE and
4351 connection auth protocol contexts and not fetched anymore in
4352 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4354 * The local hosts listenning address and port is also resolved
4355 now when starting the server. We want to have the socket object
4356 to include the real address and port for the listener. Added
4357 new function silc_net_check_local_by_sock into the files
4358 lib/silcutil/silcnet.[ch].
4360 * Fixed a broadcast bug in server -> do not broadcast if we
4363 * Fixed a routing bug. Do not route broadcast packets ever.
4364 Broadcast packets must be processed always and not routed since
4365 they may be destined to some other host than yourself and thus
4366 would get routed without no good reason. Affected file is
4369 * Added function silc_server_config_is_primary_route to check
4370 whether primary router connection has been configured (a router
4371 configuration that we are initiating). If there is not, we
4372 will assume that there is only two routers in the SILC network
4373 and we will use the incoming router connection as our primary
4374 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4376 * Changed the order of the broadcasting. Broadcast _after_ the
4377 packet has been processed not before. Affected file is
4380 * Fixed a [ClientConnection] parsing bug. The port was never
4381 parsed correctly thus resulting to port 0. Affected file
4382 silcd/serverconfig.c.
4384 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4385 argument and did not set the broadcast packet flag. Affected
4386 file silcd/packet_send.c. Fixed same bug in the function
4387 silc_server_send_notify as well.
4389 * If we receive NEW_ID packet for our own ID in the server, ignore
4392 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4396 * Removed the nickname from the Private Message Payload.
4397 Updated the code and the protocol specs.
4399 * Updated protocol specs for submitting to the IETF.
4401 * Tweaked the Random Number Generator a bit. Affected file
4402 lib/silccrypt/silcrng.c. Exported a new function
4403 silc_rng_[global]_add_noise which can be used to add more
4406 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4408 * Do not parse packets with different timeout when protocol
4409 is active -> may cause problem with rekey. Affected file
4412 * When server receives signoff notify it must not create
4413 new channel key if the client is on any channels since the
4414 sender of the signoff notify will create it.
4416 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4418 * Added printing of error messages during SKE protocol from the
4419 failure packet sent by server during SKE. Affected file
4422 * Removed the client's failure_callback handling with timeout
4423 and handle it immediately when received.
4425 * The SKE library returned wrong type in SUCCESS and FAILURE
4426 packets. They must be 32 bit MSB not 16 bit MSB.
4428 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4430 * Ok, rewrote the logic of the re-key and now it seems to work.
4431 I tested it on high traffic with frequent re-keys without
4432 problems. Added hmac_receive (and renamed hmac to hmac_send)
4433 in SilcClientConnection in lib/silcclient/client.h and
4434 in SilcIDListData in silcd/idlist.h. Also, removed the
4435 SilcPacketParserContext's cipher and hmac fields as they are
4436 not needed anymore and actually caused some problems when
4437 the ciphers and hmac's changed underneath the packet parser.
4439 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4441 * If re-key protocol is active then process the incoming packets
4442 synchronously since we must assure that icoming packets encrypted
4443 with the old key is processed before the new keys is set to
4444 use. This is true other packets than for REKEY packets.
4445 Affected file silcd/server.c. The same was done to client library
4446 as well, affected file lib/silcclient/client.c.
4448 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4450 * Fixed bug in client and server to accept the force send if
4451 the packet is send from silc_[server/client]_packet_process
4452 function. Otherwise the packets are never delivered, oops.
4454 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4456 * Disable force sending of packets when REKEY protocol is active.
4457 We must assure that no packet is sent directly when rekey is
4458 performed. All packets must be sent through packet queue.
4459 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4460 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4461 function is silc_[server/client]_packet_send_real to check
4464 * Replaced the SIM paths from example config files to
4465 /usr/local/modules. Also, make install creates now
4466 /usr/local/silc/logs directory to hold all the SILC server
4469 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4471 * Made the configure.in.pre work on Solaris. Patch by salo.
4473 * Made all ciphers compatible with non-x86 machines. Defined
4474 CBC mode macros into lib/silccrypt/ciphers_def.h.
4476 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4478 * Fixed the make install.
4480 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4482 * When MAC computation fails the silc_packet_decrypt returned 0
4483 even though it was supposed to return -1. Fixed this. The
4484 affected file is lib/silccore/silcpacket.c.
4486 * Do not replace the config files in /etc/silc (in make install)
4487 if they already exist. Affected file ./Makefile.am.
4489 * Do not send re-key packets immediately but through packet queue.
4490 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4492 * Changed silc_net_check_host_by_sock to return FALSE if the
4493 IP/DNS could not be resolved. Though, it returns the IP address
4494 now even if it could not resolve it (but returns also FALSE).
4495 Affected file lib/silcutil/silcnet.[ch].
4497 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4499 * Added silc_pkcs_decode_identifier to decode the public key's
4500 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4501 Added also silc_pkcs_free_identifier. Added also new context
4502 SilcPublicKeyIdentifier.
4504 * Added -S option to the silc client. It is used to dump the
4505 contents of the specified public key file.
4507 * Changed the PKCS api to return the public key length when
4508 setting the public key.
4510 * Fixed a fatal bug in the public and private key file loading.
4511 Affected file lib/silccrypt/silcpkcs.c.
4513 * Execute the packet parsing for client with zero (0) timeout
4514 if the protocol is active. Affected file silcd/server.c.
4516 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4518 * Made the key generation options to the silcd program. Added
4519 -C option, equivalent to client's option.
4521 * Added new [ServerKeys] config section to the server. It
4522 configures the server's public and private key.
4524 * Defined generic Public Key Payload into the protocol
4525 specification to send specific type of public keys and
4528 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4529 public key or certificate.
4531 * Implemented the GETKEY command to the server and to the
4532 client library and on user interface.
4534 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Made preliminary `make install' work.
4538 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4540 * Added SilcServerRekey context into silcd/idlist.h.
4542 * Added the PFS support as defined in the specification to the
4543 SKE protocol. Affected files lib/silcske/*.c.
4545 * Added `ske_group' field to the SilcServerRekey context to hold
4546 the number of the SKE group that is used with PFS in re-key.
4547 Affected file silcd/idlist.h.
4549 * Added PFS re-key support to the server. Affected file is
4552 * Added silc_protocol_cancel to cancel execution of the next
4553 state of the protocol. Affected file is
4554 lib/silccore/silcprotocol.[ch].
4556 * Added the re-key support with and without PFS to the client
4557 library. Re-key is performed once in an hour, by default.
4559 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4560 Added silc_client_rekey_callback and silc_client_rekey_final.
4561 Affected files are lib/silcclient/protocol.[ch] and
4562 lib/silcclient/client.[ch].
4564 * Removed the `hmac_key' and `hmac_key_len' fields from the
4565 SilcClientConnection structure; not needed. Affected file is
4566 lib/silcclient/client.h.
4570 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4572 * Do not ask whether user wants to use the negotiated private key
4573 for private messages, just use it. Affected file is
4574 silc/local_command.c.
4576 * Added `send_enc_key' and `enc_key_len' fields to the
4577 SilcIDListData structure since they are needed in the re-key
4578 phase. Affected file is silcd/idlist.[ch].
4580 * Implemented the simple re-key protocol into the server.
4581 Affected files silcd/server.c and silcd/protocol.[ch]. The
4582 re-key will be performed once in an hour, by default.
4584 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
4585 Added silc_server_rekey, silc_server_rekey_callback and
4586 silc_server_rekey_final.
4588 * Removed Tunneled flag from the protocol. Updated the code
4589 and the specifications.
4591 * Adde `pfs' field to the SilcIDListData to indicate whether
4592 the PFS is to be performed in the re-key. Affected file is
4595 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4597 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4598 int64 of at least the xintXX size. If void * is less that 4
4599 bytes uint32 * will be used. Defined bool as boolean.
4601 * Changed _ALL_ unsigned long and unsigned int to uint32,
4602 unsgined short to uint16 in the source tree.
4604 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4605 not handle clients that has entry->data.registered == FALSE.
4606 They are not in the network anymore. Affected file is
4609 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Implemented the sending of the SERVER_SIGNOFF notify in the
4612 server. Affected file is silcd/server.c.
4614 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
4615 Added also silc_notify_payload_encode_args into the
4616 lib/silccore/silcnotify.[ch].
4618 * Implemented ther SERVER_SIGNOFF notify handling in the server.
4619 Affected file silcd/packet_receive.c.
4621 * Implemented the SERVER_SIGNOFF notify handling in the client
4622 library. Affected file lib/silcclient/client_notify.c. Also,
4623 implemnted the printing of the SERVER_SIGNOFF info to the
4624 application. Affected file silc/client_ops.c.
4626 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4627 if the deleting was successful. Affected file silcd/idlist.[ch].
4629 * Added support for public key authentication in the connection
4630 authentication protocol in the client library. Affected file
4631 lib/silcclient/protocol.c.
4633 * Changed the server's silc_idlist_get_clients_by_* interface
4634 to support already allocated array so that new entries may be
4635 added to pre-allocated array. Affected file silcd/idlist.[ch].
4636 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4637 and command replies.
4639 * All command reply functions in the server now calls the
4640 pending command callback even if error occured. This way the
4641 error will be delivered to the client as well. Affected files
4642 silcd/command.c and silcd/command_reply.c.
4644 * Fixed INFO command to return local server's info if no server
4645 was provided. Affected file lib/silcclient/command.c.
4647 * Removed RESTART command for good. Updated the code and the
4650 * Rewrote parts of the task system. It is a bit simpler now.
4651 Removed unsued task priorities. The affected files are
4652 lib/silcutil/silctask.[ch].
4654 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4656 * Moved the USERS printing from the library to the application.
4657 Affected files lib/silcclient/command.c and silc/client_ops.c.
4659 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4663 * Added channel key re-key support. The re-key is perfomed
4664 only by the router and is done once in an hour. Added `rekey'
4665 field to the SilcChannelEntry in the server. Affected files
4666 silcd/server.c and silcd/idlist.h.
4668 * Added silc_task_unregister_by_context into the file
4669 lib/silcutil/silctask.[ch].
4671 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4673 * Added SILC_UMODE_GONE mode to indicate when the client is not
4674 present in the SILC network. Added also support to the local
4675 command AWAY that will set this mode. Added support of showing
4676 "xxx is gone" in WHOIS command. The USERS command shows the
4677 gone status as well.
4679 * Fixed setting server and router operator privileges in the
4680 server's UMODE command. Affected file silcd/command.c.
4682 * Merged the SKE KE1 and KE2 payloads into one payload. The
4683 new KE payload is equivalent to the old KE2 payload.
4685 Cleaned up the SKE Start Payload parsing. It now uses the
4686 simple buffer unformatting to do the parsing. A lot faster
4689 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4690 to the SKE that is used to indicate whether both of the SKE
4691 parties should perform authentication. By default only the
4692 responder performs authentication. By setting this flag also
4693 the initiator must do authentication. By default it is unset
4694 since in normal SKE case, client to server connection, only
4695 the responder should do authentication. When doing SKE between
4696 two clients both should perform authentication. Updated the
4697 code and the protocol specs.
4699 * A little fix to IDENTIFY command in the server. Search the
4700 client first by hash not nickname. Affected file is
4703 * Fixed the silc_client_close_connection to support closing
4704 the client to client connections wihtout deleting too much
4705 data. Affected file lib/silcclient/client.c.
4707 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4708 are received if protocol used to be active but is not anymore
4709 the application would crash due to NULL pointer dereference.
4710 Affected files silcd/server.c and lib/silcclient/client.c.
4712 * Added `hash' field to the SilcClientConnection to include
4713 the hash function negotiated in the SKE protocol.
4715 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4716 to set the channel founder authentication data. A client can
4717 claim the founder rights later by providing the authentication
4718 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4719 This way the channel founder can regain the channel founder
4720 privileges even it is left the channel. This works only on
4721 local server and the client must be connected to the same
4722 server to be able to regain the founder rights. Updated the
4723 protocol specs accordingly.
4725 Added support to the CMODE command in the client to set the
4726 founder auth data. Read the README to see how to set it.
4728 Added support to the CUMODE command to claim the founder
4729 rights. Read the README to see how to do it.
4731 Added support for the founder authentication to the Channel
4732 Entry in the server. Affected file silcd/idlist.h.
4734 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4735 server's CMODE command. Affected file silcd/command.c.
4737 * Added the following new functions into lib/silccore/silcauth.[ch]:
4738 silc_auth_get_method and silc_auth_get_data.
4740 * The server now saves the remote hosts public key to the
4741 SilcIDListData pointer. Affected file silcd/protocol.c.
4743 * The normal server now does not remove the channel entry from
4744 the cache if the founder authentication data is set. It used
4745 to remove it if the founder was the last one on the channel on
4746 the server and left the channel. The auth data is saved and
4747 if the channel is re-joined later the old entry is used with
4748 the old auth data. Affected files silcd/command_reply.c and
4751 * Removed the `pkcs' field from the SilcIDListData structure
4752 in the server; it is not used. Affected file silcd/idlist.h.
4754 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4756 * Fixed packet processing on slow links. Partial packets were
4757 never re-processed because the incoming data buffer was cleared
4758 by the application. Application must not directly clear the
4759 sock->inbuf, the packet processing routines handle it. Fixed
4760 this in client library and in server.
4762 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4764 * Fixed the WHOIS and IDENTIFY send reply function to really
4765 check whether to send list or just one entry. Affected file
4768 * Cleaned up the LEAVE command's channel key distribution. The
4769 affected file silcd/command.c.
4771 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4772 can enforce the channel mode as well. In that case the ID
4773 includes the ID of the server. The code now enforces the
4774 mode change if the router have different mode than the server.
4776 * The notify client operation with CMODE_CHANGE notify can now
4777 return NULL client_entry pointer if the CMODE was not changed
4778 by client. Application must check for this.
4780 * Added <Server ID> argument to INFO command to support server
4781 info fetching by Server ID.
4783 * Added silc_server_announce_get_channel_users to get assembled
4784 packets of channel users of the specified channel. Affected
4785 file silcd/server.[ch].
4787 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4788 was freed underneath the ID Cache.
4790 * Re-announce clients when the server received CHANNEL_CHANGE
4791 notify from the router. Affected file silcd/packet_send.c.
4793 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4795 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4796 crashed since it did not handle the fact that there is no cipher
4797 called "3" and didn't check the error condition. Now fixed.
4799 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4800 flag. It can be used to send message requests.
4802 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4804 * Implemented the RESTART command in the client.
4806 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4807 notice type messages. Added notice printing to the user
4810 * The channel keys are not re-generated if the channel's mode
4811 is PRIVKEY, ie private key on the channel exists. Affected
4812 files silcd/server.c and silcd/command.c.
4814 * Fixed a little bug in channel message delivery when channel
4815 private keys are set in the server. Affected file is
4816 silcd/packet_send.c.
4818 * Changed the setting on channel->on_channel = TRUE from the
4819 silc_client_save_channel_key to the JOIN command reply. The
4820 key payload is not received if the private channel key is set.
4821 Affected file lib/silcclient/command_reply.c and the
4822 lib/silcclient/client_channel.c.
4824 * When the CMODE_CHANGE notify is sent and the channel private
4825 key mode is removed the channel key must be re-generated in
4826 other cells as well. Added this support for the router in the
4827 silcd/packet_receive.c.
4829 * Added new local command NOTICE to send notice message on
4830 channel. Affected file silc/local_command.[ch].
4832 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4834 * Added new local command ME to the client. It is used to send
4835 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4836 some action. Affected file silc/local_command.[ch].
4838 * Changed channel_message and private_message client operations
4839 to deliver the message flags to the application. Added also
4840 the `flags' arguments to the silc_client_send_channel_message
4841 and silc_client_send_private_message functions. Affected file
4844 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4846 * Redefined the Private Message Payload to support private message
4847 keys and to support the new private message flags. Updated
4848 the protocol specs. Flags makes it possible to have for example
4849 CTCP style messages.
4851 * Added new type SilcPrivateMessagePayload and defined an API
4852 for it in the lib/silcclient/silcprivate.[ch].
4854 * Tested private message private keys successfully. Tested the
4855 private message key set, unset and list commands with the new
4858 * Redefined the Channel Message Payload to include the channel
4859 message flags (equal with private message flags) to support
4860 for example CTCP style messages.
4862 * Defined some of the message (for channel and private message)
4863 flags. Updated the protocol specs and added the flags to the
4864 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
4866 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4868 * Added SilcKeyAgreementStatus type to the key agreement routines
4869 to indicate the current status and error if one occured.
4870 The status types are defined in the lib/silcclient/silcapi.h.
4872 * Added new local command KEY that is used to set and unset private
4873 keys for channels, set and unset private keys for private messages
4874 with remote clients and to send key agreement requests and
4875 negotiate the key agreement protocol with remote client. The
4876 key agreement is supported only to negotiate private message keys,
4877 it currently cannot be used to negotiate private keys for channels,
4878 as it is not convenient for that purpose.
4880 * Fixed a minor pending callback setting bug in the function
4881 silc_client_get_client_by_id_resolve, now the function works.
4882 Affected file lib/silcclient/idlist.c.
4884 * Added function silc_net_get_local_port to get local bound
4885 port by socket. Added to lib/silcutil/silcnet.[ch].
4887 * Added `sockets' and `sockets_count' fields to the SilcClient
4888 object. They hold the sockets of the listenning sockets in
4889 the client. Listenning sockets may be for example the key
4890 agreement server. Affected file lib/silcclient/client.[ch].
4891 Added functions the silc_client_add_socket and the
4892 silc_client_del_socket. They are exported to the application
4895 * Added ~./silc/clientkeys to support other client's public keys.
4897 * Renamed verify_server_key client operation to verify_public_key
4898 and added one argument to indicate the type of the connection
4899 (server, client etc.).
4901 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4903 * Added silc_server_connection_auth_request to handle the
4904 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
4905 silcd/packet_receive.[ch].
4907 * Added silc_server_send_connection_auth_request into the
4908 silcd/packet_send.c to send the connection auth request packet.
4910 * Cleaned up the silcd/protocol.c a bit and fixed some memory
4913 * Fixed the public key authentication in responder side in the
4914 server. The `auth_data' pointer includes the SilcPublicKey
4915 not the path to the public key. Affected file silcd/protocol.c.
4917 * Implemented the public key authentication in the initiator side
4918 in the server. Affected file silcd/protocol.c.
4920 * Removed the [RedirectClient] config section from the server
4921 configuration. Is not needed and I don't want to implement it.
4923 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4925 * Cleaned up the CMODE command in the server. It now works
4926 correctly and supports all the modes defined in the protocol.
4927 Affected file is silcd/command.c.
4929 * Added `hmac_name' field to the SilcChannelEntry in the server
4930 to hold the default HMAC of the channel. It can be set when
4931 creating the channel (with JOIN command). Affected files
4934 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
4935 type to indicate the change of the current cipher and hmac
4936 on the channel. Client can safely ignore the <cipher> argument
4937 (if it chooses to do so) since the CHANNEL_KEY packet will
4938 force the channel key change anyway. The <hmac> argument is
4939 important since the client is responsible of setting the new
4940 HMAC and the hmac key into use.
4942 * Fixed the CMODE command in the client library as well.
4944 * Tested CMODE command in router environment successfully.
4946 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4948 * Show the version of the remote client (or server) when connecting
4949 to the server. It is logged to the log file. Affected file
4950 is silcd/protocol.c.
4952 * Fixed the KILLED notify handling in the client library. The
4953 client must be removed from all channels when receiving the
4956 Also, do not remove the client entry when giving the KILL
4957 command but when the KILLED notify is received.
4959 * Removed silc_idlist_find_client_by_nickname from the server.
4960 Not needed anymore. Affected files silcd/idlist.[ch].
4962 * Implemented the CHANNEL_CHANGE notify type handling to the
4963 server. Affected file silcd/server.c.
4967 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4969 * Added silc_server_send_notify_invite to send the INVITE
4970 notify between routers.
4972 * Implemented the INVITE command correctly to the server.
4974 * Implemented the INVITE notify type handling in the server.
4976 * Implemented the INVITE command to the client library and on the
4979 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4981 * Added function silc_server_get_client_resolve to find the
4982 client entry by ID from all ID lists and then resolve it
4983 (using WHOIS) if it cannot be found. Affected file is
4986 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4988 * Implemented the BAN command to the client library.
4990 * The JOIN command in the server now checks the invite list
4993 * Changed the silc_command_reply_payload_encode_va and the
4994 silc_command_payload_encode_va to support that if argument is
4995 NULL it ignores and checks the next argument. Affected file
4996 lib/silccore/silccommand.c.
4998 * Added silc_server_send_notify_ban to send the BAN notify
4999 type between routers.
5001 * Chaned the silc_notify_payload_encode to support that if
5002 argument is NULL it ignores and checks the next argument.
5003 Affected file lib/silccore/silcnotify.c.
5005 * Tested ban lists in router environment successfully.
5007 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5009 * Implemented BAN command to the server, in silcd/command.[ch].
5011 * Removed the BAN and INVITE_LIST modes from the CMODE command
5014 * Added function silc_string_match to regex match two strings.
5015 Affected files lib/silcutil/silcutil.[ch].
5017 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5019 * Redefined parts of the SilcChannelEntry in the server to support
5020 the new ban and invite lists.
5022 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5024 * Redefined the INVITE command. The same command can be used to
5025 invite individuals to the channel but also to manage the invite
5026 list of the channel (to add to and remove from the invite list).
5027 Updated the protocol specs.
5029 * Added new command SILC_COMMAND_BAN that can be used to manage
5030 the ban list of the channel. Updated the protocol specs.
5032 * Removed the channel modes: the SILC_CMODE_BAN and the
5033 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5034 in the CMODE command. The equivalent features are now available
5035 using INVITE and BAN commands. Updated the protocol specs.
5037 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5038 in the network about change in the current ban list. The notify
5039 type is not used by the client.
5041 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5042 support the invite lists.
5044 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5046 * Added new function silc_string_regexify that converts string
5047 including wildcard characters into regex string that can
5048 be used by the GNU regex library. Added into the file
5049 lib/silcutil/silcutil.[ch].
5051 Added silc_string_regex_combine to combine to regex strings
5052 into one so that they can be used as one regex string by
5053 the GNU regex library. Added into the file
5054 lib/silcutil/silcutil.[ch].
5056 Added silc_string_regex_match to match two strings. It returns
5057 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5059 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5061 * Imported GNU regex to the soruce tree into lib/contrib.
5062 Fixed some compiler warning from the regex.c.
5064 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5066 * Fixed MOTD command in the server to work in router environment.
5068 * Fixed the MOTD command in the client library to support
5069 the server argument in the command.
5071 * Added `nickname_len' argument to the silc_idlist_add_client
5072 in the server, as the `nickname' argument may be binary data
5075 * Added silc_idlist_get_channels to return all channels from
5078 * Implemented LIST command to the server. Affected file is
5081 * Implemented the LIST command to the client library and on the
5084 * Added [<user count>] argument to the LIST command reply.
5085 With private channels the user count is not shown.
5087 * Updated TODO and README.
5089 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5091 * The client entry's data.registered must be TRUE even with
5092 global client entry on global client list. The data.registered
5093 is used to check whether the client is anymore in the network,
5094 for example with WHOWAS command so it must be valid.
5096 * Fixed the WHOWAS command in the server. It now actually works
5097 in router environment. Added function into silcd/command_reply.c
5098 silc_server_command_reply_whowas_save.
5100 * Added silc_idlist_purge function to the silcd/idlist.c
5101 to periodically purge the ID Cache.
5103 * Fixed INFO command in the server. It works now in router
5104 environment. Added <server name> argument to the INFO command
5105 reply. Updated the protocol specs.
5107 * Fixed minor bug in silc_idcache_purge to not purge if the
5108 expire value is zero.
5110 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5111 they were buggy because of the WHOWAS information.
5113 * Fixed local command MSG to handle the async resolving of
5114 the remote client properly. It used to fail the first MSG.
5115 Affected file silc/local_command.c.
5117 * Added `data_len' field to SilcIDCache context.
5119 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5121 * Update TODO. Todo in commands in the server.
5123 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5125 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5126 used by routers as broadcast packet to inform other routers
5127 about the changed user mode.
5129 Implemented the notify handling in the server. Affected file is
5130 silcd/packet_receive.c. Added the function
5131 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5133 * Added new generic Channel Payload and deprecated the New Channel
5134 Payload. The New Channel Payload is now the generic Channel
5137 * Added new argument `mode' to the silc_server_send_new_channel
5138 as it is required in the Channel Payload now.
5140 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5141 and created a new and real SilChannelPayload to represent the
5142 new generic Channel Payload. Implemented the encode/decode
5143 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5145 * Added silc_server_get_client_channel_list to return the list
5146 of channels the client has joined for WHOIS command reply.
5147 Affected file silcd/server.[ch].
5149 * Implemented the channel list sending in the WHOIS command reply
5150 in server and in the client.
5152 Implemented the channel list displaying on the user interface
5153 as well. Affected file silc/client_ops.c.
5155 * Added silc_channel_payload_parse_list to parse list of Channel
5156 Payloads. It returns SilcDList list of SilcChannelPayloads.
5157 Client for example can use this function to parse the list of
5158 channels it receives in the WHOIS command reply. The caller
5159 must free the list by calling silc_channel_payload_list_free.
5160 Affected files lib/silccore/silcchannel.[ch].
5162 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Added one new argument <user mode> to the WHOIS command reply
5165 to return the mode of the user in SILC. Updated the protocol
5168 Implemented it to the server and client.
5170 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5172 * Fixed the mode printing on the user interface on joining.
5173 Affected file silc/client_ops.c.
5175 * Implemented the UMODE command and user modes in general to the
5176 client library and to the user interface.
5178 * Implemented the UMODE command to the server.
5180 * The server now sends UNKNOWN_COMMAND error status if client sends
5181 unknown command. Affected file silcd/command.c.
5183 * All server commands now handle the command identifier the right
5184 way when sending the command reply to the client. The client can
5185 use to identify the command replies with the identifier.
5187 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5189 * Added silc_server_get_client_route to resolve the route to
5190 the client indicated by the client ID. Affected file is
5193 * Added silc_server_relay_packet as general function to relay
5194 packet to arbitrary destination. This deprecates functions
5195 like _send_private_message_key, _relay_notify etc. Affected
5196 file is silcd/packet_send.[ch].
5198 Removed silc_server_send_key_agreement,
5199 silc_server_send_private_message_key and
5200 silc_server_packet_relay_notify functions from the file
5201 silcd/packet_send.[ch].
5205 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5206 server. Affected file silcd/packet_receive.[ch].
5208 * Implemented the KILL command to the client. Implemented the
5209 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5210 Affected files lib/silcclient/command[_reply].c and
5211 lib/silcclient/client_notify.c. Implemented the KILL notify
5212 printing in the user inteface.
5214 * Fixed a lot silc_parse_nick memory leaks from the client
5215 library in the file lib/silcclient/command.c.
5217 * Changed the silc_server_send_notify_on_channels's `sender'
5218 argument from SilcSocketConnection to SilcClientEntry to
5219 check the sender as entry and not as connection object and not
5220 to send to the client provided as argument. The affected file
5221 is silcd/packet_send.[ch].
5223 * The notify packets that are destined directly to the client used
5224 to not to be processed by the server. Now changed that and the
5225 server processes all notify packets. After relaying the packet
5226 to the client the notify packet is processed in the server.
5228 * The silc_server_free_client_data now checks whether there is
5229 pending outgoing traffic for the client and purges the data to
5230 the network before removing the client entry.
5232 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5234 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5235 an client is killed from the SILC Network. Updated the protocol
5238 Added new function silc_server_send_notify_killed to the
5239 silcd/packet_send.[ch].
5241 * Added function silc_server_packet_relay_notify to relay notify
5242 packets that are destined directly to a client. In this case
5243 the server does not process the notify packets but merely relays
5244 it to the client. Affected file silcd/packet_send.[ch].
5246 Added also silc_server_packet_process_relay_notify to check
5247 whereto relay the notify. Affected file is
5248 silcd/packet_receive.[ch].
5250 * Implemented the KILL command to the server.
5254 * Added the backup schema desgined last fall to the protocol
5255 specs for everyone to see. The specification is in the
5256 *-spec-xx.txt draft and the packet type definitions for the
5257 backup routers is in *-pp-xx.txt draft. Thusly, added also
5258 new packet type SILC_PACKET_CELL_ROUTERS.
5260 * A big security problem in the implementation discovered. The
5261 signoff of an client did not cause new channel key generation
5262 which it of course should've done. The channel keys must be
5263 always re-generated when client leaves (or signoffs) the channel.
5264 The silc_server_remove_from_channels funtion now handles
5265 the channel key re-generation.
5267 * Added `sender' argument to the silc_server_send_notify_on_channels
5268 to not to send the client provided as argument. Affected file
5269 silcd/packet_send.[ch].
5271 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5273 * Implemented OPER and SILCOPER commands into the server and
5276 * Added silc_auth_verify and silc_auth_verify_data to verify
5277 the authentication directly from the authentication payload.
5278 It supports verifying both passphrase and public key based
5279 authentication. Affected file lib/silccore/silcauth.[ch].
5281 * Added `hash' field to the SilcIDListData structure. It is the
5282 hash negotiated in the SKE protocol. Affected file is
5285 * Slight redesigning of the SilcAuthPayload handling routines.
5286 Do not send SilcPKCS but SilcPublicKey as argument.
5288 * Implemented the public key authentication support to the
5289 serverconfig. The public key is loaded from the provided path
5290 and saved as authentication data to void * pointer. Thus,
5291 changed the unsigned char *auth_data to void *auth_data;
5293 * Fixed SHUTDOWN command to send the reply before the server
5294 is shutdown. :) Affected file silcd/command.c.
5296 * Fixed fatal bug in CONNECT command. The hostname was invalid
5297 memory and server crashed. Affected file silcd/command.c.
5299 * Fixed fatal bug in CLOSE command. The server_entry became
5300 invalid but was referenced later in the command. Affected file
5303 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5305 * Fixed fatal bug in failure packet handling. Server ignored
5306 the failure and thus crashed when it came.
5310 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5313 that the command may be executed only once in (about) 2 seconds.
5314 The old SILC_CF_LAG flag is same but allows command bursts up
5315 to five before limiting.
5317 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5318 server code. Various commands now includes the CF_LAG_STRICT
5319 flag to disallow any kind of miss-use of the command.
5321 * Fixed the silc_buffer_unformat to not to allocate any data
5322 if the length of the data is zero. It used to allocate the
5323 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5325 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5327 * Changed the format of AdminConnection configuration section
5328 in the server. Added username of the admin to the format.
5329 Affected files silcd/serverconfig.[ch].
5331 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5332 to return admin configuration data by host, username and/or
5335 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5337 * Implemented WHOWAS command to the server. Added the functions:
5339 silc_server_command_whowas_parse,
5340 silc_server_command_whowas_send_reply,
5341 silc_server_command_whowas_from_client and
5342 silc_server_command_whowas_from_server
5344 * Added <Client ID> argument to the WHOWAS command reply. Updated
5345 the protocol specs accordingly.
5347 * Implemented WHOWAS command and command_reply to the client
5350 Implemented the WHOWAS printing on the user interface.
5352 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5354 * Added new argument to the WHOWAS command reply, the real name.
5355 It is an optional argument. Updated the protocol specs.
5357 * Added SilcIDCacheDestructor callback that is registered when
5358 the SilcIDCache is allocated. The callback is called when
5359 an cache entry in the ID Cache expires, or is purged from the
5360 cache. Added into lib/silccore/idcache.[ch].
5362 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5363 to destruct the client entries when the cache entry expires.
5364 Other ID Cache's in server and in the client library ignores
5367 * If the ID Cache entry's `expire' field is zero then the entry
5368 never expires. Added boolean `expire' argument to the
5369 silc_idcache_add function in the lib/silccore/idcache.[ch].
5370 If it is TRUE the default expiry value is used.
5372 * Added silc_server_free_client_data_timeout that is registered
5373 when client disconnects. By default for 5 minutes we preserve
5374 the client entry for history - for WHOWAS command.
5376 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5378 * Added support to the server to enforce that commands are not
5379 executed more than once in 2 seconds. If server receives
5380 commands from client more frequently, timeout is registered
5381 to process the commands. Affected file silcd/command.c.
5382 Added new function silc_server_command_process_timeout.
5384 * Changed NICK_NOTIFY handling in client library to check that
5385 if the client's nickname was changed, so there is no need to
5386 resolve anything from the server.
5388 * Removed error printing from the WHOIS and IDENTIFY commands.
5389 If error occurs then it is ignored silently in the client library.
5390 The application, however, may map the received error to
5391 human readable error string. The application currently maps
5392 the NO_SUCH_NICKNAME error to string.
5394 * Made the command status message public to the application. Moved
5395 them from lib/silcclient/command_reply.c to
5396 lib/silcclient/command_reply.h. The application can map the
5397 received command status to the string with the
5398 silc_client_command_status_message function.
5400 * Added check to the server to check that client's ID is same
5401 as the Source ID in the packet the client sent. They must
5404 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5406 * Added dist-bzip hook to the Makefile.am to make bzip2
5407 compressed distributions.
5409 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5411 * Server now enforces the maximum length for the nickname and
5412 the channel as protocol specification dictates. 128 bytes for
5413 nickname and 256 bytes for channel name.
5415 * Moved the WHOIS printing to the application. The client libary
5416 does not print out the WHOIS information anymore, the application
5417 must do it. Renamed silc_client_command_reply_whois_print to
5418 the silc_client_command_reply_whois_save.
5420 The client's idle time is also sent to the application now, and
5421 the idle is shown on screen.
5423 * Added silc_client_command_reply_identify_save to save the
5424 received IDENTIFY entries.
5426 * Do not check for channel private keys in message sending and
5427 reception if the channel does not have the PRIVKEY mode set.
5428 Affected file lib/silclient/client_channel.c.
5430 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5432 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5433 just surfaced after chaning the JOIN procedure.
5435 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5437 * Added silc_client_get_clients_by_list to get client entries
5438 from Client ID list, that is returned for example by JOIN
5439 and USERS command replies. The application should use this
5440 function for example when JOIN command reply is received to
5441 resolve the clients already on the channel (library does not
5442 do that anymore as USERS command reply is not used in the JOIN
5443 procedure anymore). Affected files lib/silcclient/silcapi.h and
5444 lib/silcclient/idlist.c.
5446 * JOIN command reply and USERS command reply returns now SilcBuffer
5447 pointers instead of unsigned char pointers when returning
5448 the client list and mode list.
5450 * Added <Client ID> argument to the JOIN command reply, mainly
5451 for the server to identify for which client the command was
5452 originally sent. Updated protocol specs accordingly.
5454 * Added SilcDlist private_key pointer to the SilcChannelEntry
5455 in the client to support the channel private keys. Affected
5456 file is lib/silcclient/idlist.h.
5458 * Added SilcChannelPrivateKey argument to the function
5459 silc_client_send_channel_message so that application can choose
5460 to use specific private ke if it wants to. If it is not provided,
5461 the normal channel key is used, unless private keys are set.
5462 In this case the first (key that was added first) is used
5463 as the encryption key.
5465 * Implemented the support for channel private key handling.
5466 Implemented the following functions:
5468 silc_client_add_channel_private_key,
5469 silc_client_del_channel_private_keys,
5470 silc_client_del_channel_private_key,
5471 silc_client_list_channel_private_keys and
5472 silc_client_free_channel_private_keys
5474 Affected file lib/silcclient/client_channel.c.
5476 * Added the support for the private keys in the channel message
5477 sending and encryption and in the message reception and
5478 decryption. Affected funtions are
5479 silc_client_send_channel_message and silc_client_channel_message.
5481 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5483 * Added SKE's key verify callback to the client library's
5484 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5486 * Removed the statement that server (or router) must send USERS
5487 command reply when joining to the channel so that the client
5488 knows who are on the channel. Instead, the client list and
5489 client's mode list is now sent in the JOIN command reply to the
5490 client who joined channel. This is better solution.
5492 * Added function silc_server_get_users_on_channel and function
5493 silc_server_save_users_on_channel to the silcd/server.[ch].
5495 * Removed function silc_server_command_send_users from the
5498 * Do not show topic on the client library anymore. The topic is
5499 sent in the command reply notify to the application and the
5500 application must show the topic now.
5502 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5504 * Added client searching by nickname hash into the IDENTIFY and
5505 WHOIS commands in the server as they were clearly missing from
5506 them. Affected file is silcd/command.c.
5508 * Fixed a bug in private message receiving in the client library.
5509 The remote ID was freed and it wasn't supposed, now it is
5512 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5514 * Minor fix to the channel payload; allocate the data area, as it
5515 needs to be of specific length.
5517 * If the key agreement port is zero then the operating
5518 system will define the bound port. Affected files are
5519 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5521 * Added new function silc_channel_payload_decrypt into the file
5522 lib/silccore/silcchannel.[ch].
5524 * Moved the channel message etc, check from silc_packet_decrypt
5525 to applications. The library calls now a generic
5526 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5527 when the packet is either normal or special. This was done to
5528 allow more wide range of checking that was not allowed when
5529 the code was in library. Now applications can do virtually any
5530 checks to the packet and return to the library the decision how
5531 the packet should be processed. Affected files are
5532 lib/silccore/silcpacket.[ch].
5534 Added silc_server_packet_decrypt_check to the server and
5535 silc_client_packet_decrypt_check to the client library.
5537 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5538 to send with specified source and destination information.
5540 * Channel message delivery between routers was broken after the
5541 channel key distribution was fixed earlier. The channel key
5542 was used be to distributed to other routers as well which is not
5543 allowed by the protocol. Now this is fixed and channel keys
5544 really are cell specific and the channel message delivery between
5545 routers comply with the protocol specification.
5547 * Fixed various commands in server to check also the global list
5548 for the channel entry and not just the local list. The affected
5549 file silcd/command.c.
5551 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5553 * Added assert()s to buffer formatting and unformatting routines
5554 to assert (if --enable-debug) when error occurs. Affected
5555 file: lib/silcutil/silcbuffmt.c.
5557 * Changed to auto-reconnect to check whether the remote host is
5558 router and register the re-connect timeout if it is. It used
5559 to check that whether we are normal server, but router must do
5560 auto-reconnect with another router as well. Affected file
5563 * Removed the [<key len>] option from CMODE command as the cipher
5564 name decides the key length, nowadays. See the defined ciphers
5565 from the protocol specification.
5567 * Added [<hmac>] option to the CMODE command to define the HMAC
5568 for the channel. Added SILC_CMODE_HMAC channel mode.
5570 * Added [<hmac>] option for the JOIN command so that user can
5571 select which HMAC is used to compute the MACs of the channel
5574 * Added Hmac field to the Channel Message Payload. The integrity
5575 of plaintext channel messages are now protected by computing
5576 MAC of the message and attaching the MAC to the payload. The
5577 MAC is encrypted. Now, it is clear that this causes some
5578 overhead to the size of the packet but rationale for this is that
5579 now the receiver can verify whether the channel message decrypted
5580 correctly and also when private keys are set for the channel the
5581 receiver can decrypt the packet with several keys and check from
5582 the MAC which key decrypted the message correctly.
5584 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5585 lib/silccrypt/silccipher.[ch].
5587 * Added silc_hash_len to return the digest length into the
5588 lib/silcrypt/silchash.[ch].
5590 * Rewrote parts of Silc Channel Payload interface in the
5591 lib/silccore/silcchannel.[ch]. The encode function now also
5592 encrypts the packet and parse function decrypts it.
5594 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5596 * Fixed a minor formatting bug in the SKE's key material processing.
5597 It actually might have processed the keys wrong way resulting
5600 * Redefined the mandatory HMAC algorithms and added new algorithms.
5601 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5602 and hmac-md5 truncated to 96 bits. The mandatory is now
5603 hmac-sha1-96. Rest are optional (including the one that used
5604 to be mandatory). Rationale for this is that the truncated HMAC
5605 length is sufficient from security point of view and can actually
5606 make the attack against the HMAC harder. Also, the truncated
5607 HMAC causes less overhead to the packets. See the RFC2104 for
5610 * Added new [hmac] configuration section. The SKE used to use
5611 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5612 is of course wrong. The official names that must be proposed in
5613 the SKE are the ones defined in the protocol specification
5614 (hmac-sha1-96 for example). The user can configure any hmac
5615 using any hash function configured in the [hash] section. At
5616 least, the mandatory must be configured.
5618 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5620 * Added HMAC list to the SKE proposal list. It has now both
5621 hash algorithm list and HMAC list. This makes the protocol
5622 incompatible with previous versions. The SKE now seems to work
5623 the way it is supposed to work, for the first time actually.
5625 * Defined plain Hash algorithms to the protocol specification.
5628 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5630 * Implemented support for key agreement packets into the server.
5631 Added functions silc_server_key_agreement and
5632 silc_server_send_key_agreement. Other than these functions,
5633 server has nothing to do with this packet.
5635 * Added support for private message key packets into the server.
5636 Added functions silc_server_private_message_key and
5637 silc_server_send_private_message_key.
5641 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5642 called in the protocol's final callback instead in the END
5643 protocol state. This makes a little more sense and in the same
5644 time in client we can use the same protocol routines for normal
5645 key exchange and to key agreement packet handling as well.
5647 * Added to both client's and server's KE protocol context the
5648 SilcSKEKeyMaterial pointer to save the key material. We will
5649 bring the key material to the protocol's final callback by doing
5650 this. The final callback must free the key material.
5652 * Added SKE's packet_send callback into client's KE protocol
5653 context so that the caller can choose what packet sending function
5654 is used. This way we can use different packet sending when
5655 doing normal SKE when doing key agreement packet handling (in
5656 the key agreement packet handling we do not want to encrypt
5659 * Implemented the responder side of the key agreement routines
5660 in the client. The client can now bind to specified port and
5661 accept incoming key negotiation. The key material is passed
5662 to the application after the protocol is over.
5664 * Implemented the processing of incoming Key Agreement packet
5665 in the client. Added function silc_client_key_agreement to
5668 * Implemented the intiator side of the key agreement routines
5669 in the client. The client can now initiate key agreement with
5670 another remote client. The key material is passed to the
5671 application after the protocol is over.
5673 * Created client_keyagr.c to include all the key agreement
5676 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5677 SILC_TASK_CALLBACK except that it is not static.
5679 * Created client_notify.c and moved the Notify packet handling
5680 from the client.[ch] into that file.
5682 * Created client_prvmsg.c and moved all private message and
5683 private message key routines from the client.[ch] into that file.
5685 * Create client_channel.c and moved all channel message and
5686 channel private key routines from the client.[ch] into that file.
5688 * Changed silc_client_get_client_by_id_resolve to resolve with
5689 WHOIS command instead of IDENTIFY command, in the file
5690 lib/silclient/idlist.c.
5692 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5694 * Implemented the SKE's responder side to the Client library.
5696 * When FAILURE is received to the protocol do not trust it
5697 blindly. Register a timeout to wait whether the remote closes
5698 the connection as it should do it, only after that process the
5699 actual failure. This was changed to both client and server.
5701 * Added client_internal.h to include some of the structures
5702 there instead of client.h in lib/silcclient/.
5704 * Added function silc_task_unregister_by_callback to unregister
5705 timeouts by the callback function.
5707 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5709 * Some "Incomplete WHOIS info" errors has been appearing on the
5710 log files. Took away the entry->userinfo check from WHOIS
5711 reply sending. The entry->userinfo is now " " if client did not
5712 provide one. I thought this was fixed earlier but something
5713 is wrong still. Let's see if the error still appears.
5715 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5717 * Fixed a minor bug in the login when the channel key is
5718 re-generated in the server. It used to generate the key in
5719 wrong order and thus caused problems in the channel traffic.
5721 * Fixed a minor bug in channel key distsribution after
5722 KICK command. The key was not sent to the router even though
5725 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5727 * Added silc_ske_process_key_material_data as generic routine
5728 to process any key material as the SILC protocol dictates. The
5729 function is used by the actual SKE library but can be used by
5730 applications as well. This relates to the private message keys
5731 and the channel private keys since they must be processed the
5732 same way the normal SILC session keys. The protocol dictates
5733 this. Affected files: lib/silcske/silcske.[ch].
5735 Added also silc_ske_free_key_material to free the
5736 SilcSKEKeyMaterial structure.
5738 * Defined silc_cipher_set_key function to set the key for
5739 cipher without using the object's method function. The affected
5740 files: lib/silccrypt/silccipher.[ch].
5742 * Implemented silc silc_client_add_private_message_key,
5743 silc_client_add_private_message_key_ske,
5744 silc_client_del_private_message_key,
5745 silc_client_list_private_message_keys and
5746 silc_client_free_private_message_keys functions in the
5749 Added functions silc_client_send_private_message_key to send
5750 the Private Message Key payload and silc_client_private_message_key
5751 to handle incoming Private Message Key payload.
5753 * Added Cipher field to the Private Message Key payload to set
5754 the cipher to be used. If ignored, the default cipher defined
5755 in the SILC protocol (aes-256-cbc) is used.
5757 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5759 * Removed lib/silcclient/ops.h file.
5761 Redefined parts of the SILC Client Library API. Created new
5762 file silcapi.h that deprecates the ops.h file and defines the
5763 published Client Library API. Defined also private message key
5764 API and channel private key API into the file.
5766 This is the file that the application must include from the
5767 SILC Client Library. Other files need not be included by
5768 the application anymore.
5770 * Added new key_agreement client operation callback and also
5771 defined the Key Agreement library API for the application.
5773 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5775 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5776 is used by clients to request key negotiation between another
5777 client in the SILC network. If the negotiation is started it
5778 is performed using the SKE protocol. The result of the
5779 negotiation, the secret key material, can be used for example
5780 as private message key.
5782 Implemented the Key Agreement payload into the files
5783 lib/silccore/silauth.[ch].
5785 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5787 * Redefined ciphers for the SILC protocol. Added some new ciphers
5788 and defined the key lengths for the algorithms. Changed the
5789 code accordingly. The default key length is now 256 bits.
5791 * Fixed SKE key distribution function silc_ske_process_key_material
5792 when the key length is more than 128 bits. The default key
5793 length in SILC is now 256 bits.
5795 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5796 to indicate unsupported algorithm.
5798 * Renamed rijndael.c to aes.c and all functions as well.
5800 * Fixed a long standing channel key setting bug in client library.
5801 Weird that it has never surfaced before.
5803 * Fixed bug in channel deletion. If the entire channel is removed
5804 then it must also delete the references of the channel entry
5805 from the client's channel list as the client's channel entry and
5806 the channel's client entry share same memory.
5808 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5810 * Implemented CONNECT and SHUTDOWN commands in the client.
5812 * Implemented CLOSE command to the client.
5814 * Added the function silc_idlist_find_server_by_name into the
5815 files silcd/idlist.[ch].
5817 Added the function silc_idlist_find_server_by_conn into the
5818 files silcd/idlist.[ch].
5820 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5822 * DIE command was renamed to SHUTDOWN. Updated the both code
5825 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5826 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5828 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5831 * Added function silc_server_create_connection function to create
5832 connection to remote router. My server implementation actually
5833 does not allow router to connect to normal server (it expects
5834 that normal server always initiates the connection to the router)
5835 so the CONNECT command is only good for connecting to another
5838 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5840 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5841 or some other client was kicked from the channel.
5843 Implemented the handling of the notify type to both client
5846 Implemented silc_server_send_notify_kicked to send the KICKED
5847 notify. It is used to send it to the server's primary router.
5849 * Implemented the KICK command into server and client.
5851 * Added `query' argument to the silc_idlist_get_client function
5852 to indicate whether to query the client from server or not if
5855 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5856 to indicate that the client is not channel founder.
5860 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5862 * Removed the rng context from SilcPacketContext structure and
5863 changed that the packet routine uses the Global RNG API.
5865 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5867 * Added support for quit message that client can "leave" on the
5868 channel when it quits the SILC. It is ditributed inside the
5869 SILC_NOTIFY_TYPE_SIGNOFF notify type.
5871 Added silc_server_free_client_data that will take the
5872 signoff message as argument.
5874 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
5876 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5878 * Updated parts of the protocol specification to keep it up
5881 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5883 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
5884 payloads in one packet.
5886 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
5887 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
5888 use now the new List flag.
5890 * Also deprecated the following packet types: REPLACE_ID,
5891 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
5893 * Added list support for Notify packet in server.
5895 * Added silc_server_send_notify_channel_change to send the
5896 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
5897 the silc_server_send_replace_id.
5899 * Added silc_server_send_notify_nick_change to send the
5900 NICK_CHANGE notify type. Deprecates the function
5901 silc_server_send_replace_id.
5903 * Added silc_server_send_notify_join to send the JOIN notify type.
5904 Deprecates the function silc_server_send_new_channel_user.
5906 * Added silc_server_send_notify_leave to send LEAVE notify type.
5907 Deprecates the function silc_server_send_remove_channel_user.
5909 * Added silc_server_send_notify_cmode and
5910 silc_server_send_notify_cumode to send CMODE and CUMODE notify
5911 types. Deprecates the silc_server_send_set_mode function.
5913 * Added SERVER_SIGNOFF notify type to indicate that server has
5914 quit. This means that all clients on the channel from that
5915 server will drop. This can be also used when netsplit happens.
5917 Deprecated REMOVE_ID packet type since it is not needed anymore
5920 Added silc_server_send_notify_server_signoff to send the
5921 SERVER_SIGNOFF notify type. Deprecates the function
5922 silc_server_send_remove_id.
5924 Added also silc_server_send_notify_signoff to send the
5925 SIGNOFF notify type.
5927 * Employed the PKCS #1. It is the mandatory way to do RSA in the
5928 SILC protocol from this day on. Changed the protocol
5929 specification as well.
5931 * Added silc_server_send_notify_topic_set to send TOPIC_SET
5932 notify type. It is used between routers to notify about
5933 topic changes on a channel.
5935 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
5938 * Partly updated the protocol specification to comply with the
5939 changes now made. It is still though a bit outdated.
5941 * The JOIN notify type now takes one extra argument <Channel ID>.
5942 The packet used to be destined to the channel but now the
5943 JOIN type may be sent as list thus it is impossible to
5944 destine it to any specific channel. By adding this argument
5945 it is again possible.
5947 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5949 * Added CREDITS file. The CHANGES and CREDITS file will appear
5950 in the distribution as well.
5952 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5954 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
5955 types in the server's silcd/packet_receive.c.
5957 * Implemented CMODE and CUMODE to work in router environment.
5959 * Fixed minor encoding and decoding buglet from the
5960 lib/silccore/silcmode.c.
5962 * Fixed buffer overflow from lib/silcclient/command.c in USERS
5965 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
5967 * Changed all SilcConfigServer* and silc_config_server* to
5968 SilcServerConfig* and silc_server_config*, respectively.
5971 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5973 * Associated the ID (client or server ID) to the Authentication
5974 Payload to avoid any possibility of forging. Updated the
5975 protocol specification and the code accordingly.
5977 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5979 * The RSA key length is now save to the RsaKey context in the
5980 key generation process in lib/silccrypt/rsa.c. The key length
5981 is now used to figure out the maximum size of the block allowed
5982 to be encrypted/signed.
5984 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
5985 is equivalent to the silc_mp_mp2bin but does not allocate any
5988 * Changed silc_mp_mp2bin API to take length argument. If it is
5989 non-zero then the buffer is allocated that large. If zero, then
5990 the size is approximated using silc_mp_sizeinbase, which however
5993 * Created Global RNG API which is global RNG that application can
5994 initialize. After initializing, any routine anywhere in the
5995 code (including library) can use RNG without allocating a new
5996 RNG object. This was done to allow this sort of use of the
5997 RNG in code that has no chance to allocate RNG object. All
5998 applications currently allocate this and many routines in the
5999 library use this. Affected file lib/silccrypt/silcrng.[ch].
6001 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6002 it to use the Global RNG API.
6004 * Defined Authentication Payload into protocol specification that
6005 is used during SILC session to authenticate entities. It is
6006 used for example by client to authenticate itself to the server
6007 to obtain server operator privileges.
6009 Implemented this payload into the lib/silccore/silcauth.[ch].
6010 Implemented also routines for public key based authentication
6011 as the new protocol specification dictates.
6013 Moved definitions of different authentication methods from
6014 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6016 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6017 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6018 silc_pkcs_verify_with_hash functions into the file
6019 lib/silccrypt/silcpkcs.[ch].
6021 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * The client entry's userinfo pointer must be always valid.
6024 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6025 will fail since it requires the userinfo. Now, the userinfo
6026 is allocated as "" if actual userinfo does not exist. Actually,
6027 it must exist and it is totally Ok to drop client connections
6028 that does not announce the userinfo. However, we will make
6029 this workaround for now.
6031 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6032 to return the remote port by socket.
6034 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6036 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6037 SILC_SERVER_PENDING_EXEC and added an new macro
6038 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6039 data or when error occurs while processing the pending command.
6041 Added new argument `destructor' into silc_server_command_pending
6042 and to the SilcServerCommandPending object. This destructor is
6043 now called after calling the pending callback or if error occurs
6044 immediately. If error occurs the actual pending callback won't
6045 be called at all - only the destructor. The destructor may be
6046 NULL if destructor is not needed.
6048 All this applies for client library code as well. Similar
6049 changes were made there as well for the pending commands.
6051 In the client, the application must now allocate the
6052 SilcClientCommandContext with the silc_client_command_alloc
6055 * Added reference counter to the SilcServerCommandContext. Added
6056 function silc_server_command_alloc and silc_server_command_dup
6059 Same type of functions added to the client library for the same
6062 * Removed the cmd_ident from IDListData away since it is now
6063 global for all connections. It is the command identifier used
6064 in command sending and with pending commands. The affected file
6067 * Added reference counter to the SilcSocketConnection objecet to
6068 indicate the usage count of the object. The object won't be
6069 freed untill the reference counter hits zero. Currently only
6070 server uses this, and client ignores it. The client must be
6071 set to use this too later. The affected files are
6072 lib/silccore/silcsockconn.[ch]. Added also the function
6073 silc_socket_dup to increase the reference counter.
6075 This was mainly added because it is possible that the socket
6076 is removed underneath of pending command or other async
6077 operation. Now it won't be free'd and proper DISCONNECTING
6078 flags, etc. can be set to avoid sending data to connection that
6079 is not valid anymore.
6081 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6082 the connection. After that it sets SILC_SET_DISCONNECTED.
6083 It is, however, possible that the socket data is not still freed.
6084 The silc_server_packet_process now checks that data is not
6085 read or written to connection that is DISCONNECTED. The socket
6086 get's freed when the reference counter hits zero.
6088 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6090 * Changed the client operation API: channel_message operation's
6091 `sender' is now the client entry of the sender, not the nickname
6092 and the `channel' is the channel entry, not the channel name.
6094 In the private_message operation the `sender' is now also the
6095 client entry of the sender not the nickname.
6097 Affected file is lib/silcclient/ops.h and all applications
6098 using the client operations.
6100 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6102 * Moved the calling of ops->connect() from connect_to_server_final
6103 into receive_new_id functin since that is the point when the
6104 client is actually allowed to send traffic to network. The
6105 affected file is lib/silcclient/client.c.
6107 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6109 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6110 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6111 (if needs broadcasting) instead of broadcasting the packets one
6112 by one which would make a burst in the network traffic.
6114 * Added `broadcast' argument to the functions in silcd/server.[ch]
6115 silc_server_create_new_channel[_with_id] to indicate whether
6116 to send New Channel packet to primary router.
6118 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6120 * Added new function into the silcd/server.[ch] files:
6121 silc_server_create_new_channel_with_id to create new channel with
6122 already existing Channel ID.
6124 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6125 lib/silccore/silcpacket.h. This packet is used t send list of
6126 Set Mode payloads inside one packet. Server uses this to set
6127 the modes for the channels and clients on those channels, that it
6128 announced to the router when it connected to it. The protocol
6129 specification has been updated accordingly.
6131 * The silc_server_new_channel did not handle the packet coming
6132 from normal server as it normally does not send that. However,
6133 when it announces its channels it does send it. Implemented
6134 the support for that.
6136 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6137 into the file lib/silccore/id.h.
6139 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6141 * Fixed memory leaks in the functions silc_idlist_del_client,
6142 silc_idlist_del_channel and silc_idlist_del_server in the file
6143 silcd/idlist.c. All of those leaked like a sieve.
6145 * Fixed some small memory leaks in the client's function
6146 silc_client_notify_by_server.
6148 * Added functions into silcd/server.c: silc_server_announce_clients,
6149 silc_server_announce_channels and silc_server_announce_server.
6150 These functions are used by normal and router server to announce
6151 to its primary router about clients, channels and servers (when
6152 router) that we own. This is done after we've connected to the
6155 These functions effectively implements the following packet types:
6156 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6157 and SILC_PACKET_NEW_ID_LIST.
6159 * Added new functions into the silcd/packet_receive.[ch]:
6160 silc_server_new_id_list, silc_server_new_channel_list and
6161 silc_server_new_channel_user_list to handle the incoming
6162 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6164 * Added support of changing Channel ID in the function
6165 silc_server_replace_id. If the server that announces a channel
6166 to the router already exists in the router (with same name but
6167 with different Channel ID), router is responsible to send
6168 Replace ID packet to the server and force the server to change
6169 the Channel ID to the one router has.
6171 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6172 client that the Channel ID has been changed by the router. The
6173 normal server sends this to the client. Client must start using
6174 the new Channel ID as the channel's ID.
6176 Implemented handling of this new type into lib/silcclient/client.c
6177 into the function silc_client_notify_by_server.
6179 * Added new function silc_idlist_replace_channel_id into the files
6180 silcd/idlist.[ch] to replace the Channel ID.
6182 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6184 * Call silc_server_command_identify_check always when processing
6185 the IDENTIFY command in silcd/command.c
6187 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6189 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6190 send keepalive packets. The packet can be sent by clients,
6191 servers and routers.
6193 Added function silc_socket_set_heartbeat into the file
6194 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6195 If not set, the heartbeat is not performed. The actual
6196 heartbeat is implemented in the low level socket connection
6197 library. However, application is responsible of actually
6200 Added silc_server_send_heartbeat to send the actual heartbeat
6201 packet into silcd/packet_send.[ch]. Server now performs
6202 keepalive with all connections.
6204 * Added silc_task_get_first function into lib/silcutil/silctask.c
6205 to return the timeout task with shortest timeout. There was a bug
6206 in task unregistration that caused problems. TODO has been
6207 updated to include that task system must be rewritten.
6209 * The client library will now resolve the client information when
6210 receiving JOIN notify from server for client that we know but
6211 have incomplete information.
6213 * Rewrote parts of silc_server_remove_from_channels and
6214 silc_server_remove_from_one_channel as they did not remove the
6215 channel in some circumstances even though they should've.
6217 * Encryption problem encountered in server:
6219 The LEAVE command used to send the Channel Key packet to the
6220 router immediately after generating it. However, the code
6221 had earlier sent Remove Channel user packet but not immediately,
6222 ie. it was put to queue. The order of packets in the router
6223 was that Channel Key packet was first and Remove Channel User
6224 packet was second, even though they were encrypted in the
6225 reverse order. For this reason, MAC check failed. Now, this
6226 is fixed by not sending the Channel Key packet immediately but
6227 putting it to queue. However, this is more fundamental problem:
6228 packets that are in queue should actually not be encrypted
6229 because packets that are sent immediately gets encrypted
6230 actually with wrong IV (and thus MAC check fails). So, packets
6231 that are in queue should be encrypted when they are sent to
6232 the wire and not when they put to the queue.
6234 However, the problem is that the current system has not been
6235 designed to work that way. Instead, the packet is encrypted
6236 as soon as possible and left to the queue. The queue is then
6237 just purged into wire. There won't be any fixes for this
6238 any time soon. So, the current semantic for packet sending
6241 o If you send packet to remote host and do not force the send
6242 (the packet will be in queue) then all subsequent packets to the
6243 same remote host must also be put to the queue. Only after the
6244 queue has been purged is it safe again to force the packet
6247 o If you send all packets immediately then it safe to send
6248 any of subsequent packets through the queue, however, after
6249 the first packet is put to queue then any subsequent packets
6250 must also be put to the queue.
6252 Follow these rules and everything works fine.
6254 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6256 * Added new function silc_server_remove_clients_by_server to
6257 remove all client entries from ID list when the server connection
6258 is lost. In this case it is also important to invalidate all
6259 client entires as they hold the invalid server entry. This
6260 fixes fatal bug when server has lost connection and will reconnect
6263 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6265 * Made some sanity checks to silc_server_daemonise like to check
6266 whether the requested user and group actually exists.
6268 * Added sanity check to SKE's silc_ske_responder_finish to check
6269 that the public and private key actually is valid.
6271 * Invalidate the client's nickname when receiving Replace ID
6272 packet and the Client ID is being replaced. This means that the
6273 server will query the nickname if someone needs it (client)
6276 * Sort the ID Cache in client library when the ID Cache data
6277 has changed (needs sorting).
6279 * Do not allow for SILC client to create several connections to
6280 several servers. The client does not support windows right now
6281 and generating multiple connections causes weird behaviour.
6283 Irssi-silc client does support windows and can handle several
6284 connections without problems, see: www.irssi.org and SILC plugin.
6286 * Fixed some places where client was added to the IDList. The
6287 rule of thumb is following (in order to get everything right):
6288 If the client is directly connected local client then the
6289 `connection' argument must be set and `router' argument must be
6290 NULL to silc_idlist_add_client function. If the client is not
6291 directly connected client then the `router' argument must
6292 bet set and the `connection' argument must be NULL to the
6293 silc_idlist_add_client function.
6295 * The funtion silc_server_packet_send_local_channel actually did
6296 not check whether the client was locally connected or not. It
6297 does that now. Fixed a bug related to LEAVE command.
6299 * Fixed Remove Channel User payload parsing bug in server's
6300 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6302 * The server's silc_server_save_channel_key now checks also the
6303 global ID list for the channel as it might not be in the local
6304 list. Fixed a bug related to LEAVE command.
6306 * Is this the end of the [<unknown>] buglet that has been lurking
6307 around for a long time? A little for loop fix in server's
6308 silc_server_command_whois_parse that is used by both IDENTIFY
6309 and WHOIS command. At least, this was a clear bug and a cause
6310 of one type of [<unknown>] buglet.
6312 * WHOIS and IDENTIFY commands call the function
6313 silc_server_command_[whois/identify]_check function even if
6314 we are not router server.
6316 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6318 * Added --with-gmp configuration option. If set the GMP
6319 is always compiled in the SILC source tree. If not set then
6320 it is checked whether the system has the GMP3 installed. If
6321 it has then the GMP won't be compiled (the system's headers
6322 and library is used), if it doesn't have it then the GMP is
6323 compiled in the SILC source tree.
6325 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6327 * Changed RSA private exponent generation to what PKCS #1
6328 suggests. We try to find the smallest possible d by doing
6329 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6330 not security fix but optimization.
6332 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6334 * Added new config entry [Identity] to fork the server and run
6335 it as specific user and group. A patch from Bostik.
6337 * Imported Dotconf configuration library into lib/dotconf.
6338 This will be used to create the SILC configuration files later.
6339 It will appear in the distsribution after this commit.
6341 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6343 * A big code auditing weekend happening. Auditing code for
6344 obvious mistakes, bugs and errors. Also, removing any code
6347 Removed files for being obsolete:
6349 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6350 inline in the file lib/silcutil/silcbuffer.h)
6352 o lib/silcutil/silcbufutil.c (the header has inline versions)
6354 Changed code to fix possible error conditions:
6356 o The buffer formatting routines now check that the destination
6357 buffer really has enough space to add the data. This applies for
6358 both buffer formatting and unformatting
6359 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6360 unformatting was changed to accomodate following rules:
6361 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6362 sent to the function while XXX_*STRING will not allocate or copy
6363 the data into the buffer. Instead it sets the pointer from the
6364 buffer into the pointer sent as argument (XXX_*STRING used to
6365 require that the pointer must be allocated already). This change
6366 makes this whole thing a bit more consistent and more optimized
6367 (note that the data returned in the unformatting with XXX_*STRING
6368 must not be freed now). The routines return now -1 on error.
6370 o Tried to find all code that use buffer_format and buffer_unformat
6371 and added return value checking to prevent formatting and
6372 especially unformatting errors and possible subsequent fatal
6375 o Changed ske->x and ske->KEY to mallocated pointers in
6376 lib/silcske/silcske.h. Fixed possible data and memory leak.
6378 o Added return value checking to all *_parse* functions. Fixed
6379 many memory leaks as well.
6381 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6382 so that buffer overflows would not happen. All code now also
6383 checks the return value as it can fail.
6385 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6387 * Added reconnection support to server if the normal server looses
6388 its connection to the router (for example if router is rebooted).
6389 The server performs normal reconnection strategy implemented
6390 to the server. Affected file silcd/server.c.
6392 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6394 * Added new packet type SILC_PACKET_SET_MODE that is used to
6395 distribute the information about changed modes (for clients,
6396 channels and clients channel modes) to all routers in the
6397 network. Updated the protocol specification accordingly.
6399 Added functions into silcd/packet_send.c and
6400 silcd/packet_receive.c: silc_server_send_set_mode,
6401 silc_server_set_mode.
6403 Added new files silcmode.[ch] into lib/silccore that implements
6404 the encoding and decoding of Set Mode Payload. Added new type
6405 SilcSetModePayload. Moved the definitions of different modes
6406 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6408 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6410 * Oops, a little mistake in server's connection authentication
6411 protocol. The protocol is not ended with FAILURE but with
6412 SUCCESS if the authentication is Ok. :) Affected file is
6415 * Implemented NICK_CHANGE notify handling in server in the file
6416 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6417 the local clients on the channel. After the changing nickname
6418 in router environment snhould work and the [<unknown>] nickname
6419 should appear no more.
6421 The silc_server_replace_id function that receives the Replace ID
6422 payload now sends the NICK_CHANGE notify type also in the file
6423 silcd/packet_receive.c
6425 * Changed WHOIS and IDENTIFY command to support the maximum amount
6426 of arguments defined in protocol specs (3328 arguments). This
6427 fixed a bug that caused problems when there were more than three
6430 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6432 * Added extra parameter, command identifier, to the
6433 silc_client_send_command so that explicit command identifier
6436 Changed that ID list routines uses specific command identifier
6437 when sending WHOIS/IDENTIFY requests to the server so that they
6438 can be identified when the reply comes back.
6440 Affected files lib/silcclient/command.[ch],
6441 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6443 * Added `sender' argument to silc_server_packet_send_to_channel
6444 to indicaet the sender who originally sent the packet to us
6445 that we are now re-sending. Ignored if NULL. Affected file
6446 silcd/packet_send.[ch].
6448 * Added some server statistics support in silcd/server_internal.h
6449 SilcServerStatistics structure and around the server code. Also
6450 send some nice statistics information when client is connecting
6453 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6455 * Fixed channel ID decoding in server's JOIN command reply in
6456 silcd/command_reply.c
6458 * Fixed braodcasting of replace ID payload to not to send it if
6459 we are standalone server in silcd/packet_receive.c.
6461 * Fixed all channel message sending routines to not to send
6462 packets to clients that has router set, since they are routed
6463 separately in the same function earlier. Affects file
6464 silcd/packet_send.c and all channel packet sending functions.
6466 * In USERS reply, res_argv[i] are not allocated, the table
6467 is allocated. Thus changed that free the table, not its
6470 * In server's whois_check and identify_check if the client is
6471 locally connected do not send any WHOIS commands - they are not
6474 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6476 * Fixed some minor bugs in client when sending WHOIS command. The
6477 arguments was in wrong order.
6479 * Removed statis function add_to_channel from server in
6480 silcd/command.c that was previously used with the joining but
6483 * Tested USERS command in router environment successfully with two
6484 routers, two servers and two clients.
6486 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6488 * Reorganized the USERS command and command reply in client library
6489 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6490 When the command is given by user we register a pending command
6491 callback that will reprocess the command after the reply has been
6492 received from the server. When reprocessing the packet we then
6493 display the information. Thus, the USERS information is displayed
6494 now in the command callback instead of in the command reply
6495 callback. The processing of the command is same as previously
6496 when server has sent the command reply in the JOINing process.
6498 * Added to USERS command in silcd/command_reply.c to join the client,
6499 we didn't use to know about, to the channel after we've created
6500 a client entry for it. Also, for clienet we did know already still
6501 check whether it is on the channel or not and add it if not.
6503 * Removed silc_server_command_join_notify as the function and its
6506 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6508 * Changed the client's pending command handling to the same as the
6509 server's pending command handling. It is also now possible to
6510 execute command reply functions from other command reply
6511 function as the function callbacks for commands and command
6512 replies are one and same. The pending commands are not static
6513 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6514 in client connection context. Thus, pending commands are server
6515 connection specific as it is convenient.
6517 Changed the function silc_client_command_pending and
6518 silc_client_command_pending_del and added new function
6519 silc_client_command_pending_check. Removed the
6520 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6523 * Added cmd_ident, current command identifier, to the client
6524 connection context in lib/silcclient/client.h to keep track on
6525 command identifiers used in command sending. Client's command reply
6526 function handling now supports the mandatory command identifiers.
6528 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6529 funtions in client to fully support pending command callbacks.
6531 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6532 as one of the arguments to the application in the command reply
6535 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6536 before first releasing SILC but came back. Now it is removed again
6537 and should come back nomore. The FORWARDED flag was used only
6538 by the JOINing procedure by forwarding the command packet to router.
6539 Now, the JOINing procedure has been changed to more generic (due
6540 to various router environment issues) and FORWARDED is not needed
6541 anymore for anything. The protocol specification is yet to be
6544 Now, removed silc_server_packet_forward from server and the flag
6545 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6547 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6549 * Renamed NAMES command to USERS command. The NAMES was named that
6550 due to historical reasons. Now it is renamed. Also, rewrote
6551 parts of the USERS command. The nickname list is not sent anymore
6552 by the server. Only Client ID and mode lists are sent in the USERS
6553 command. Changed this also to the protocol specification.
6555 The client now resolves the names and stuff after it receives
6556 the USERS list from the server when joining to the channel.
6558 * WHOIS and IDENTIFY commands has been changed to support multiple
6559 Client ID's per command. One can now search for multiple users
6560 in the network by sending only one WHOIS or IDENTIFY command.
6561 Changed the code and the protocol specifications.
6563 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6564 uses silc_server_command_whois_parse to parse the request. */
6566 * If normal server, do not parse the WHOIS and IDENTIFY requests
6567 before sending it to the router. Saves some time.
6569 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6571 * Fixed JOIN command on client library. Wrong number of arguments
6572 used to crash the client.
6574 * Added silc_server_channel_has_global function to check whether
6575 channel has global users or not.
6577 * Added silc_server_channel_has_local function to check whether channel
6578 has locally connected clients on the channel.
6580 * The silc_server_remove_from_one_channel now checks whether the
6581 channel has global users or not after given client was removed from
6582 the channel. It also checks whether the channel has local clients
6583 on the channel anymore. If it does not have then the channel entry
6584 is removed as it is not needed anymore.
6586 * The silc_server_notify now checks on JOIN notify whether the joining
6587 client is one of locally connected or global. If it is global then
6588 the channel has now global users on the channel and that is marked
6589 to the channel entry. Also, it now saves the global client to
6590 global list who is joining and JOINs it to the channel. This is
6591 for normal server, that is.
6593 Changed silc_server_send_notify_on_channel,
6594 silc_server_packet_relay_to_channel and
6595 silc_server_packet_send_to_channel check if we are normal server
6596 and client has router set (ie. global client) do not send the
6597 message to that client, as it is already routed to our router.
6599 * Implemented LEAVE notify type handling in silc_server_notify
6602 * Tested LEAVE command in router environment successfully. Tested
6603 with two routers, two servers and two clients.
6607 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6609 * Implemented SIGNOFF notify type handling in silc_server_notify
6612 * silc_server_remove_id now removes the client entry from all channels
6613 it has joined and thusly sends SIGNOFF notify type.
6615 * Rewrote the NAMES list generation in server by removing two excess
6616 loops. The lists are created now inside one loop.
6618 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6620 * silc_server_remove_channel_user checks now also global list
6621 for channel and client.
6623 * silc_server_new_channel_user checks now both local and global
6624 list for channel and client. Fixed a bug in client id decoding.
6625 Used to decode wrong buffer.
6627 * silc_server_channel_message checks now both local and global
6628 list for channel entry.
6630 * Tested channel joining (hence JOIN) in router environment
6631 successfully. Tested with two routers, two servers and two
6634 * Tested channel message sending in router environment successfully.
6636 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6638 * Added silc_server_save_channel_key into server.[ch] to save the
6639 received channel key in Channel Key payload processing. It is
6640 also used in JOIN command reply handling.
6642 Equivalent function silc_client_save_channel_key added into
6643 client.[ch] into client library.
6645 * Changed JOIN command reply to send information whether the channel
6646 was created or not (is existing already) and the channel key
6647 payload. Changed protocol specs accordingly.
6649 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6650 the request was sent by ID and not by nickname. Crashed on
6653 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6655 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6656 now correctly save the received data.
6658 * silc_server_free_sock_user_data now notifies routers in the
6659 network about entities leaving the network.
6661 At the same time implemented functions silc_server_remove_id
6662 and silc_server_send_remove_id to receive and send REMOVE_ID
6663 packets. The packet is used to notify routers in the network
6664 about leaving entities. The ID removed will become invalid in
6667 * Added function silc_idlist_del_server into server. Removes and
6668 free's server entry from ID list.
6670 * silc_server_private_message function now checks, if we are router,
6671 that the destination ID really is valid ID, naturally.
6673 * In router when NEW_ID packet is received (for new client) the
6674 hash of the Client ID is saved in the ID Cache but the
6675 client->nickname is set to NULL, instead of putting the hash
6678 IDENTIFY command now also checks that client->nickname must be
6679 valid. If it is not if will request the data from the server who
6680 owns the client. Added new function
6681 silc_server_command_identify_check.
6683 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6684 to set the command to already allocated Command Payload.
6686 * Tested private message sending in router environment with two
6687 routers, two servers and two clients. Fixed minor bugs and now
6690 * Fixed segfault from client's NAMES command. Used to crash if
6693 * Forwarded packets must not be routed even if it is not destined
6694 to the receiver. Changed server code comply with this.
6696 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6698 * Added `require_reverse_mapping' boolean value to ServerParams
6699 structure. If TRUE (not default) the server will require that
6700 the connecting host has fully qualified domain name.
6702 If the reverse mapping is not required and hostname could not be
6703 found the IP address is used as hostname.
6705 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6707 * Implemented version string checking to both client and server.
6708 The check is incomplete currently due to the abnormal version
6709 strings used in development version of SILC.
6711 * Changed all command functions in server to use the new
6714 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6716 * Changed char *data to unsigned char *data in ID Cache system to
6717 support binary data as ID Cache data. Changed code to support
6718 binary data in lib/silccore/idcache.c.
6720 * Renamed silc_server_packet_relay_command_reply to
6721 silc_server_command_reply as it is normal packet receiving
6722 function. Rewrote the function to accept command replys for
6723 servers and not only for clients.
6725 * Mark remote router always as registered server if we are connecting
6726 to it. Otherwise, commands sent by the router to us are ignored.
6728 * All ID List find routines now returns the ID Cache Entry pointer
6729 as well if requested.
6731 * WHOIS command works now in router environment, tested with two
6732 routers, two servers and two clients.
6734 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6735 in router environment (as it is almost equivalent to WHOIS) but
6736 hasn't been tested thoroughly. Added new functions:
6738 silc_server_command_identify_parse
6739 silc_server_command_identify_send_reply
6740 silc_server_command_identify_from_client
6741 silc_server_command_identify_from_server
6743 * Disabled route cache adding because adding two different ID's with
6744 same IP replaces the old cache entry thus giving wrong route.
6745 The entry->router->connection is always the fastest route anyway
6746 so route cache may not be needed. Of course, new routes maybe
6747 established after receiving the ID when the entry->router->connection
6748 might not be anymore the most optimal.
6750 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6752 * Add route cache for received ID for fast routing.
6754 * Added silc_server_packet_route to route received packet on router
6755 that is not destined to us.
6757 * Renamed silc_server_get_route to silc_server_route_get.
6759 * Added id_string and id_string_len fields into SilcServer to
6760 include encoded ServerID for fast comparing without excess
6761 encoding of the ID's.
6763 * Cleaned up WHOIS command on server side. Added following static
6766 silc_server_command_whois_parse
6767 silc_server_command_whois_check
6768 silc_server_command_whois_send_reply
6769 silc_server_command_whois_from_client
6770 silc_server_command_whois_from_server
6772 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6773 arguments in command replies. All command functions should be
6774 updated to use this macro.
6776 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6778 * Minor typo fixes on command reply handling on server.
6780 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6782 * Added silc_server_command_add_to_channel internal routine to add
6783 the client to the channel after router has created the channel and
6784 sent command reply to the server.
6786 * Added generic silc_server_send_command to send any command from
6789 * Use static buffer with ID rendering instead of duplicating data.
6791 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6793 * Fixed a channel user mode bug when joining to a channel server gave
6794 everybody channel founder rights, oops.
6796 * We mark ourselves as the router of the incoming server connection
6797 if we are router ourselves. This way we can check in some packet
6798 sending functions whether it is locally connected server. For
6799 incoming router connections we put NULL.
6801 * For router sending packets locally means now always sending the
6802 packet cell wide; to local clients and local servers. For normal
6803 server sending packet locally means sending it to only local
6806 * Fixed the JOIN command to really work in router environment. If the
6807 channel is created it is always created by the router. Router is
6808 also responsible of making the initial joining to the channel,
6809 sending JOIN notify to the sending server and distributing
6810 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6811 does not exist server doesn't do anything else but forward the
6812 command to the router which performs everything.
6814 * Added silc_server_send_channel_key function to send the Channel Key
6817 * Added silc_server_create_channel_key to create new channel key. The
6818 channel key is now re-generated everytime someone joins or leaves
6819 a channel, as protocol dictates. Note: channel->key_len is the
6822 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6824 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6825 packet_receive.[ch] to separate packet sending and receiving
6826 routines. The server.[ch] now includes everything else including
6827 actual packet processing (writing and reading data) and other
6830 Renamed silc_server_private_message_send_internal to
6831 silc_server_send_private_message. The routine is still though
6832 used only to relay private messages as server does not send
6833 private messages itself.
6835 Renamed silc_server_new_channel to silc_server_create_new_channel
6836 and added new function sicl_server_new_channel that handles the
6837 incoming New Channel packet. Added also new sending function
6838 silc_server_send_new_channel to send New Channel Payload.
6840 * Added new function silc_server_notify to process incoming notify
6841 packet to the server/router. Server may then relay the notify
6842 to clients if needed.
6844 * Added new function silc_server_new_channel_user to process incoming
6845 New Channel User packet. Router will redistribute the packet and
6846 send JOIN notify to its local clients and locally connected servers
6847 if needed. Normal server will send JOIN notify to its local client
6848 on same channel when received this packet. Added also corresponding
6849 sending function silc_server_send_new_channel_user to sent the
6852 * Added boolean route argument to send_notif_to_channel and
6853 packet_send_to_channel functions to attempt to route the packet
6854 if it is TRUE and send only locally if it is FALSE.
6856 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6858 * silc_server_replace_id now broadcasts the received replace ID
6859 packet if it is not broadcast packet already. The router must
6860 broadcast to inform other routers about changed ID.
6862 * Added backpointer to server's router into SilcServer context in
6863 silcd/server_internal.h.
6865 * Fixed silc_server_packet_broadcast to send correct broadcast
6868 * The channel key is now distributed to the local client as soon
6869 as it is received from the router (in router environment) so that
6870 no other packet may be sent for the channel until client has
6873 * silc_server_remove_channel_user now broadcasts the received
6874 Remove Channel User packet if it is not broadcast packet already.
6875 The router must broadcast to inform other routers about removed
6878 * Added users field into SilcPacketContext that is a reference count
6879 of the context. One can increase the reference count by calling
6880 silc_packet_context_dup which is now changed to just increase the
6881 reference count instead of duplicating the data. The reference
6882 count is decresed by calling silc_packet_context_free that will
6883 free the data after the reference count hits zero.
6885 For now on the packet context and everything allocated into it
6886 (including the raw packet from network) must be freed by calling
6887 the new silc_packet_context_free function. Added also new function
6888 silc_packet_context_alloc that must be used now to allocate the
6889 context. This also means that if a routine is asynchronous from
6890 silc_[client/server]_packet_parse_type the packet context must
6891 be duplicated by calling silc_packet_context_dup. Otherwise it
6892 gets free'd after silc_[client/server]_packet_parse_type returns.
6893 Also, one must remember that if packet is duplicated then its
6894 reference count must be decresed by calling the free function as
6895 many times as it was duplicated.
6897 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
6898 from both client and server.
6900 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6902 * Made joining to a channel working in router environment.
6904 * Cleaned up JOIN command on server side and create function
6905 silc_server_command_join_channel internal routine to make the
6908 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6910 * Changed silc_command_pending list to SilcDList. Also, added
6911 `ident' field to SilcServerCommandPending structure to identify
6912 the reply and to call correct callback.
6914 Added silc_server_command_pending_check function to replace the
6915 corresnponding macro. The silc_command_pending list is not
6918 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
6919 to set identifier to previously allocated Command Payload. It
6920 is used to set identifier for command when resending Command
6923 * Added silc_command_payload_encode_payload to encode Command
6924 Payload buffer from SilcCommandPayload structure.
6926 * Added silc_argument_payload_encode_payload to encode Argument
6927 payload buffer from SilcArgumentPayload structure.
6929 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6931 * Changed WHOIS command to support router connection on server side.
6932 The whois request is always sent to router unless the server is
6933 standalone server. After server has received the reply from the
6934 router will it send the reply to the client.
6936 * Added silc_server_packet_broadcast into silcd/server.[ch] to
6937 broadcast received broadcast packet. The function is used only
6938 by router. The broadcast packet is always sent to the router's
6941 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
6942 render given ID to printable string, for log files for example.
6944 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6946 * Made basic router to router connections working. At least they
6947 can now connect to each other but nothing really works the way
6948 they are supposed - yet.
6950 * Added new initiator token to RouterConnection configuration
6951 file in silcd/serverconfig.[ch]. It is used to tell whether we
6952 are the initiator to the remote router or whether we'll expect
6953 the other end to connect.
6955 * Moved registering of listener task to silc_server_init, hence
6956 the server starts listenning as soon as it is run, even if it
6957 does not have connections to other routers. Let's see how well
6960 * Changed default connection retry timeouts for more suitable in
6963 * Removed cipher and such arguments from silc_idlist_add_client
6964 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
6965 Added new function silc_idlist_add_data to add the keys and stuff
6968 * Added SilcIDListData structure and added it to SilcClientEntry
6969 and SilcServerEntry as their first field in the structure. This
6970 way we can explicitly cast the ID entries to the SilcIDListData
6971 structure and get common data for the entries. In past, we had
6972 to first check what type of connection it is and then cast it to
6973 correct ID entry type. Now, we can directly cast the opaque
6974 pointer to the SilcIDListData (no matter what ID entry it actually
6975 is) and get the data needed.
6977 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6979 * Wow, found a bug in scheduler. The scheduler uninitialized itself
6980 in some circumstances even if threre were timeout tasks, though not
6981 IO tasks, but tasks anyway. Now fixed.
6983 * Defined SilcServerConnection structure to hold connection specific
6984 stuff about directly connected servers and routers. The definition
6985 is currently in silcd/server_internal.h. I thought about having
6986 a bit more important role fro this struct but for now it is used
6987 only when connecting to other server (or router actually).
6989 * Added connecting retry support in server when connecting to
6990 router(s). The retry feature implement exponential backoff
6991 algorithm. Also, added SilcServerParams structure to hold default
6992 parameters for server. For now, it include these retry settings
6993 and are hard coded. After server is moded to be as Silc Server
6994 Library this structure will be more important.
6996 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6998 * Changed client librarys channel->clients table to SilcList and
6999 changed code accordingly.
7001 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7003 * Changed client's channel table to SilcList and changed code
7004 accordingly. Also changed SilcChannelClientEntry to include back-
7005 pointer to the channel so that client entry can use that structure
7006 as list as well and we have fast cross-reference to the channel.
7007 This change dramatically decreased the complexity of channel
7008 handling with client entry and vice versa (removed one extra
7009 loop when searching for channel entry from many functions).
7011 * Changed server->sim from table to SilcDList and changed code
7014 * NAMES command can now be used from user interface. It will show
7015 the user list on the channel, neatly.
7017 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7018 Code now saves realname of the user if it becomes available.
7020 * Renamed configure.in to configure.in.pre and made ./prepare
7021 script to automatically add correct version string to
7022 configure.in which it creates from configure.in.pre.
7024 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7026 * NAMES command reply now shows users mode with the nickname when
7029 * Moved silc_client_ch[u]mode[_char] functions from
7030 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7031 place sucks, they are utility functions and should be in some
7034 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7036 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7039 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7043 * Added TRQ (efficient deque and list library) into lib/trq. This is
7044 a very good list library that is currently used in the SILC. Defined
7045 SilcList API over the library because I didn't like the API very
7046 much. See lib/trq/silclist.h for the API and examples of how to
7047 use the API. Fixed various places in the code to use the new
7048 SilcList API. The SilcList is meant for lists that has a structure
7049 already defined as a list. It is not suitable to add just some
7050 context to the list (in TRQ, the context is the list actually).
7052 So, I defined SilcDList that can be used for the purpose where
7053 predefined list structure does not exit. This can be used as
7054 such list. Now some context just can be added to the SilcDList.
7055 Currently this list is not used in the SILC just yet, though there
7056 are a lot places where this can replace dynamically allocated
7057 tables and I will fix these places, later, to use SilcDList.
7058 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7059 and use TRQ internally).
7061 Also fixed some annoying warning messages that the original TRQ
7062 code generated. Also minor changes to TRQ's Makefile.in.
7064 * Added support for querying by Client ID to both WHOIS and
7065 IDENTIFY commands into server, as required by the protocol.
7067 * Removed method function pointers from SilcBuffer structure. They
7068 weren't used to anything and just increased the context size for
7069 no good reason. This change also made silc_buffer_alloc and
7070 silc_buffer_free functions inline functions.
7072 * Disabled command flooding detection support until it's fixed so
7073 that it accepts commands in but does not execute them more than once
7076 * Added silc_net_localhost(), to return local hostname, into
7077 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7078 that must be initialized before calling silc_client_init.
7080 * Added new function: silc_server_send_notify_on_channels to send
7081 notify messages to all channels client has joined. It is assured
7082 that the message is sent only once per client.
7084 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7085 lib/silcutil/silcutil.[ch] as silc_format function. The new
7086 function is generic and is used by server as well, not only by
7087 the logging routines.
7089 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7090 the provided version string was not acceptable. Added new function:
7091 silc_ske_check_version into lib/silcske/silcske.h. The function
7092 must be implemented by the application (client or server) and it
7093 does not reside in the SKE library. The function checks the version
7094 string remote end sent.
7096 * Added back pointers (to opaque context and to SilcSocketConnection)
7097 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7099 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7100 duplicate packet context structure.
7102 * Changed `notify' client operation to send same arguments as client
7103 receives from server except for ID's. ID's are mapped to correct
7104 ID entry and that is returned. Also, if channel entry is not sent
7105 by server but the notify is for channel the channel entry is sent
7106 to application (otherwise application doesn't know that it is for
7107 channel (library gets it from packet's Destination ID)).
7109 * Added silc_client_remove_from_channels into client library to
7110 remove a client from all channels it has joined to. Used when
7111 received SIGNOFF notify from server. Added also new function
7112 silc_client_replace_from_channels to replace old ID entry with
7113 new ID entry on all channels. Used when received NICK_CHANGE
7116 * Fixed ID Cache list handling in silc_idlist_get_client in
7117 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7118 to get (or query) client by ID.
7120 * Updated TODO list.
7122 * Added connection authentication status message defined by the
7123 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7124 support for these into the code in client and server side.
7126 * Added generic function silc_client_send_command to send any command
7127 with variable argument list. Application should use this function
7128 to send commands if the command functions provided by the library
7129 does not suite for the application's user interface needs.
7131 * Added new `failure' client operation. Application is notified about
7132 received failure packet if client is executing a protocol. In this
7133 case the protocol's execution has failed.
7135 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7136 is required by the protocol.
7138 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7139 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7142 * Added status flag to SilcSKE object to indicate realtime status
7143 of the SKE protocol.
7145 * Application receives now exactly same command reply arguments as
7146 the library receives from server. However, if ID is received the
7147 corresponding ID entry is returned to the application (eg. Client
7148 ID is mapped to correct SilcClientEntry entry and that is returned).
7149 Changed command_reply client operation due to this change.
7151 * Changed all ID's in commands and in command replys as ID Payloads.
7152 Change affected both client and server side codes.
7154 All ID's sent in SILC network (with execption of ID's in SILC
7155 Packet header) are sent in ID Payload to support variable length
7158 * Server now notifies nick changes and notifies all clients on
7159 the channels about the new nickname (about the new Client ID,
7162 * Implemented CMODE command to change channel modes. Supports all
7163 channel modes defined by the protocol specs except ban and invite
7164 lists. (Also, private channel key mode is supported but support for
7165 setting private channel key in client is missing, thus, this mode
7166 has no effect on client side (except that server requires that the
7167 client uses private channel key and normal channel traffic does not
7170 Also, invite mode works per se, but INVITE command does not work
7171 yet correctly, so you can set channel as invite only channel but
7172 inviting clients to the channel does not work (it is yet to be
7173 thought what's the best way to do it).
7175 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7176 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7177 Implemented CUMODE command to change user's mode on the channel.
7178 Supports all modes defined by the protocol specs.
7180 * Added NAMES command reply to return users modes on the channel.
7182 * Removed unnecessary and slow ciphers from lib/silccrypt.
7184 * Set SO_KEEPALIVE option to connection sockets by default.
7186 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7188 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7189 redefined the Notify Payload into protocol specs.
7191 * Added silc_id_payload_parse_id to get ID directly from raw
7194 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7196 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7197 accept searching by Client ID as well.
7199 * Added support for LEAVE and SIGNOFF notify types in client library.
7201 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7202 to parse ID Payload from raw data.
7204 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7206 * Added flags parameter into silc_ske_assemble_security_properties
7207 function in lib/silcske/silcske.[ch].
7209 * Changed notify client operation to fit better for notify messages
7210 sent by server. The notify payload received from server is now
7211 passed to the application (after parsing it to SilcNotifyPayload).
7212 It is application's responsibility to retrieve the arguments
7213 from the payload and show the message the way it wants. The message
7214 sent by server is implementation specific.
7216 * Changed public keys to comply with the protocol specification.
7217 Old public keys are not supported anymore and are not compatible.
7219 * Removed nickname from Channel Payload as the latest draft removed
7220 it. The client must resolve the nickname from the NAMES command
7221 reply received when it joined the channel.
7223 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7225 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7227 * Fixed some errors in protocol specification drafts.
7229 * Created lib/silccore/silcnotify.c to implement Notify Payload
7230 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7231 generic payloads described by protocol specifications. The file
7232 includes implementations for ID Payload and Argument Payload.
7234 * Changed Command Payload implementation to use the new Argument
7235 Payload. Changed command_xxxx_payload to command_payload_xxxx
7236 to comply with SILC coding conventions.
7238 * Added suppport for Argument Payload handling in Notify Payload
7239 implementation as protocol requires it. Added the new support
7240 into server and client lib as well.
7242 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7244 * Added support for multiple nicknames on same channel. [n] is
7245 added locally to the nickname if there are more than one same
7246 nicknames on the channel.
7248 * Server now sends all nicknames that matched WHOIS request.
7249 Client also shows the list received from server.
7251 * Added TOPIC command to client side. User can now set and show
7252 current topic on channel.
7254 * Added MOTD command to client and server. Also, server sends the
7255 motd when client connects to the server.
7257 * Changed version strings to comply ISO 8601.
7259 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7261 * Fixed protocol error handling in client library. It should now
7262 cope even if the SKE fails for some reason.
7264 * Made new protocol specification drafts for submitting to IETF.
7266 * Implemented TOPIC command to server in silcd/command.c.
7268 * Added two new notify types into lib/silccore/silcnotify.h:
7269 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7270 notify nickname change and topic setting/change on a channel.
7272 * API change of command_reply operation in client library. The
7273 application gets now the status type received from server as well.
7275 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7277 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7279 * Cras fixed and optimized the packet handling even further and
7280 it should work now. Minor change to the prototype of function
7281 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7283 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7285 * Added new function into lib/silcutil/silcschedule.[ch]:
7286 silc_schedule_with_fd to select() a specified fd. The function
7287 returns after timeout expires or data arrives or goes. The
7288 function is used by packet routines to wait that all data is
7289 received from network.
7291 * Fixed data reading from network in lib/silccore/silcpacket.c.
7292 The code now assures that all data is read from the fd and then
7293 continues packet processing. This was a bug fix since the code
7294 used to drop some data in some circumstances.
7296 * Added new function into lib/silcclient/client.[ch]:
7297 silc_client_start_key_exchange to start key exchange after
7298 connection has been established to server. The code internally
7299 now uses this funtion but its main purpose was to provide it
7300 for applications that perform their own connecting. After
7301 application has created a connection it merely calls this
7302 function to start the key exchange between client and server.
7303 The library takes care of everything else after that.
7305 Updated also lib/silcclient/README to explain the usage of
7308 * Do not send to application information that connection has
7309 been established. Application gets notified it by connect
7312 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7314 * Applied cras's patch to add silc_schedule_one function. The
7315 function runs scheduler once and returns.
7317 * Fixed the scheduler after cras messed it up. The timeout
7318 handling works now as it's supposed to work.
7320 * Added into lib/silccore/ silcnotify.h to include notify
7321 message types support. Changed silc_server_send_notify*
7322 functions, in server.[ch], to support those new notify types.
7323 Added the support for the notify types into client library,
7324 as well. Added new notify client operation into ops.h in
7327 * Changed silc_server_packet_send_to_channel to send normal
7328 packets instead of just channel message packets. The function
7329 is now used to send the notify packets to channels. It is not
7330 used to send channel message packets anymore, as server never
7333 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7334 va_arg()s as it seems to require it nowadays. I guess, if SILC
7335 is compiled with older va_arg() the new code should work anyway.
7337 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7339 * Splitted core library. Core library (lib/silccore) includes
7340 now only SILC protocol specific core (and common) components.
7341 Created new utility library (lib/silcutil) that includes more
7342 generic purpose stuff. The stuff for util library was taken
7343 from the old core library. This was minor and easy split.
7345 * Created SILC Client Library (lib/silcclient) that includes
7346 implementation of the SILC client without user interface. This
7347 was major move from silc/ directory. The code has been changed
7348 so that it is transparent towards the user interface. The
7349 silc/ directory includes now the same user interface as before
7350 and it uses the new client library. Read lib/silcclient/README.
7351 Basicly, the client library performs everything else related
7352 to SILC except user interface handling. Also, configuration
7353 files are considered to be part of user interface and library
7354 does not handle them.
7356 This change also changed a lot of structures, function naming etc.
7357 Most important change was that SilcClientWindow object was
7358 renamed to SilcClientConnection in the client library. Created
7359 also new file lib/silcclient/ops.h. Also added new files
7360 silc/local_command.[ch] and silc/client_ops.[ch].
7362 All these changes were made to make it easier for user interface
7363 designers to create what ever user interface for the SILC client
7366 It is also expected that the server will be moved to lib
7367 directory as well and SILC Server Library will be created;
7368 sometimes in the future.
7370 * Removed Local commands from lib/silccore/silccommand.h as
7371 they are application specific and new client library does not
7372 handle any of those anymore.
7374 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7375 old client implementation in silc/.
7377 * Added support for callback functions in SILC_LOG_* macros.
7378 Application can now set its own callbacks that will be called
7379 instead of using the default functions that will always print
7380 the debug messages to stderr (or stdout). Also, debugging can
7381 now be disabled by setting silc_debug to FALSE and re-enabled by
7382 setting it to TRUE. Note, that logging will still work even
7383 if debugging is disabled.
7385 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7386 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7387 silc_log_reset_debug_callbacks.
7389 * To enable debugging in silc client one must give now -d
7390 option on command line.
7392 * Changed silc_schedule_init to automatically allocate task queues
7393 if they are not allocated before calling it.
7395 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7397 * Added GMP 3.1 into math library.
7399 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7401 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7402 a channel in SILC network. The packet is used by servers and
7403 routers to notify other routers that user has left a channel.
7404 This little feature was missing until now. Added the feature
7405 to protocol specification as well.
7407 Added functions: silc_server_send_remove_channel_user and
7408 silc_server_remove_channel_user into server.[ch].
7410 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7411 lib/silccore/silcpacket.h. However, they are not implemented
7414 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7416 * Fixed joining to a channel and sending channel messages
7417 between server and router. The channel message sending should
7418 now work inside a cell.
7420 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7422 * Fixed the private message sending between server and router.
7423 The private message sending should now work inside a cell.
7425 * Added silc_server_replace_id into server.[ch] to replace
7426 existing ID in the SILC network.
7428 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7429 and silc_idlist_replace_server_id into idlist.[ch] in server.
7431 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7433 * Fixed the server to server connections. Server can again now
7434 connect to router. Router to router connections probably does
7437 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7439 * Added dynamic protocol registering support. Now protocols can
7440 registered and unregistered on the fly. Patch by cras.
7442 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7444 * Added lib/contrib directory to hold routines that some platforms
7445 don't have but are needed by SILC.
7447 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7448 into lin/contrib to provide getopt() and getopt_long() for
7449 those who don't have it.
7451 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7453 * Added AWAY command to client. When away message is set and
7454 client receives a private message packet the client automatically
7455 replies to the sender with the away message.
7457 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7458 bug seemed to be the cause of recent problems when compiling
7461 * Added version detection support to SKE protocol specification
7462 and added the new changes to the SKE implementation as well.
7463 There were other minor changes in the SKE protocol as well.
7465 Many changes in lib/silcske/silcske.[ch] and in
7466 lib/silcske/payload.[ch].
7468 * Added ^U functionality, clear input line. Patch from cras.
7470 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7472 * Mainly small bugfixes on core library. Fixed some debugging
7473 logging and buffer overflow in silclog.c.
7475 * Updated config.sub and config.guess on the distribution tree.
7477 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7479 * Added command lagging support in server. Client may execute
7480 commands now only once in two seconds.
7482 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7484 * Optimized packet reception. MAC computation and checking is now
7485 also more optimized. A lot previously duplicated code is now
7486 used as generic by both client and server.
7488 * Fixed key pair generation in clientutil.c
7490 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7492 * Added into lib/silccore/silcbufutil.[ch] new function;
7493 silc_buffer_realloc.
7495 * Moved generic packet sending/encryption functions to
7496 lib/silccore/silcpacket.[ch] from client and server. Some
7497 rewriting of the functions.
7499 * Moved all generic packet reception/decryption functions to
7500 lib/silccore/silcpacket.[ch] from client and server. The
7501 packet processing is now much cleaner in both client and server.
7502 These were major changes in both client and server.
7504 * Created many common functions in server to do packet sending.
7505 Previously code were duplicated a lot, this has been removed
7508 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7510 * Rewrote major parts of the ID cache system. Don't know
7511 whether it is better now or not but at least the API is more
7514 * Major rewrite on ID cache stuff on client because of the ID
7515 cache API changes. Added idlist.c to client.
7517 * Also major rewrite on ID cache stuff on server as well.
7518 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7519 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7520 in hand, instead they are all put into the ID cache system now.
7521 All server_idlist_* routines uses ID cache now instead of
7522 traversing its own lists (those lists does not exist anymore).
7523 SilcIDList though still exists. Also, SilcXXXEntry's are
7526 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7528 * Finally made the SKE implementation compliant to the protocol
7529 specification. All mp integers are now binary encoded as
7530 opposed being HEX encoded.
7532 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7535 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7536 functions: silc_[encode/decode]_pem. Also added function
7537 silc_encode_pem_file to PEM encode with newlines ('\n') for
7540 * SILC public keys are now encoded either PEM or binary. Same
7541 option is for private keys as well. By default private keys
7542 are binary encoded and public keys PEM encoded. Silly HEX
7543 encoding were removed.
7545 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7546 function to create fingerprints.
7548 * Fixed a bug in SHA1; does not change the original data anymore.
7550 * Partly implemented INFO command on client and server side.
7551 Fixed CLEAR command. Changes to SERVER command; show current
7552 server(s) when giving command without arguments. Added
7553 VERSION command to client.
7555 * Added check to server that unregistered connections cannot
7556 execute commands (unless it is specificly allowed).
7558 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7560 * Fixed screen refresh.
7562 * Fixed channel joining bug from client. On some circumstances
7563 client tried to join to a channel it had already joined.
7565 * Added public key verification process into client's protocol.c.
7566 The client now verifies the public key from user and saves
7567 it into ~./silc/serverkeys/ directory.
7569 Added into: clientutil.[ch]: silc_client_verify_server_key.
7571 * Changed SKE protocol's silc_ske_initiator_finish function
7572 to accept callback function that verifies the received public
7573 key. Removed old silc_ske_verify_public_key function.
7575 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7577 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7578 silc_pkcs_private_key[_data]_set.
7580 * Made the password and public authentication more cleaner in
7581 server's protocol.c.
7583 * Removed historic and obsolete protocol `channel_auth' from
7584 both client and server.
7586 * Removed wrong way of sending command status messages from
7587 server to client in server's command.c. The old way violated
7588 protocol specification.
7590 Changes to silccore/silccommand.[ch]: removed
7591 silc_command_encode_status_payload -> not needed anymore,
7592 changed silc_command_encode_payload_va to accept extra
7593 argument on variable argument list. The argument type must
7594 now be provided to the function. Also, added new function:
7595 silc_command_encode_reply_payload_va which is same as
7596 normal command_encode_payload_va except command status type
7597 is provided as extra argument.
7599 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7601 * Added ~./silc directory handling. The directory includes the
7602 public and private keys for the client.
7604 Added silc_client_check_silc_dir, silc_client_create_identifier
7605 and silc_client_load_keys.
7607 * Implemented SILC protocol compliant public key. Added public
7608 and private key saving to and loading from files.
7610 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7611 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7612 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7613 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7614 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7616 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7617 silc_pkcs_load_[public/private]_key.
7619 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7621 * Added silc_server_get_route (route.[ch]) to get connection
7622 data for the fastest route for given ID.
7624 * Implemented INVITE command on client and server. The command
7625 were re-defined in the SILC Protocol Specification and the
7626 implementation now complies with the specification.
7628 * Implemented PING command on client and server.
7630 * Implemented NAMES command on client and server. The server side
7631 supports currently only normal server not router server yet.
7632 Some changes to NAMES definition in SILC protocol specification.
7634 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7636 * Implemented LEAVE command on client and server.
7638 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7639 again. This change was made to the protocol as well. Server
7640 should not violate the protocol specification anymore.
7642 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7644 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7645 was tested. SOCKS4 was not but should work anyway.
