1 Fri Mar 29 10:41:07 EET 2002 Pekka Riikonen <priikone@silcnet.org>
3 * And yet again reverted back the config thing since Johnny
4 screwed it up. Affected file silcd/serverconfig.[ch], server.c,
7 Fri Mar 29 03:26:12 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
9 * Added preliminary checking during config parsing for a valid
10 public/private key and removed further checks in the code.
11 Affected files are silcd/serverconfig.[ch], server.c.
13 * Moved functions silc_server_drop() and silc_server_daemonise()
14 from server.c to silcd.c since they are stricly related to
15 the application activity.
17 * Reverted a small part of the automatic ref/unref since
18 it caused a double unref in some situations. Affected
19 files are silcd/silcd.[ch], server.c, serverconfig.c.
21 * Added some .cvsignore files in the lib directory.
23 Thu Mar 28 22:51:15 EET 2002 Pekka Riikonen <priikone@silcnet.org>
25 * Fixed silc_net_gethostbyaddr to correctly resolve by
26 address. Affected file lib/silcutil/silcnet.c.
28 * Fixed the notify relaying to client. The HMAC to be used
29 with relayed packets ws wrong and caused decryption failure
30 at the client end. Affected file is silcd/packet_receive.c.
32 Thu Mar 28 19:02:05 EET 2002 Pekka Riikonen <priikone@silcnet.org>
34 * Created new branch silc_protocol_1_0_branch.
36 * Reverted the silc_log_quick change in lib/silcutil/silclog.c.
38 * Changed the silc_server_config_* routines to be SilcServer
39 independent. They are now officially application specific code
40 and not part of generic server implementation. Affected files
41 are silcd/serverconfig.[ch], silcd/silcd.c, silcd/server.c.
43 Thu Mar 28 17:01:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
45 * Added automatic referencing of config context in the
46 silc_server_config_alloc, and automatic unreferencing in the
47 silc_server_config_destroy. Affected files are
48 silcd/serverconfig.[ch], silcd/silcd.c.
50 * Fixed the silc_log_quick handling in the logging routines.
51 It didn't log quickly when it was TRUE. Affected file is
52 lib/silcutil/silclog.c. Also the flush delay was set even
53 if it was 0 in config file. Affected file is
56 * Added support for changing key pair of the server in rehash.
57 Affected file silcd/server.c.
59 Thu Mar 28 12:17:21 CET 2002 Pekka Riikonen <priikone@silcnet.org>
61 * Fixed the TOPIC_SET notify to not cras. It changed the topic
62 too early, before getting the channel entry. Affected file
63 is silcd/packet_receive.c.
65 Thu Mar 28 09:58:16 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
67 * Added functions silc_server_config_[ref/unref], these are used
68 to prevent that the config object is destroyed.
70 No longer directly affect global variables silc_log_quick and
71 silc_log_delay, they are first cached inside the config object
72 and then applied with silc_server_config_setlogfiles().
74 silc_server_config_set_defaults() is now internal to
75 serverconfig.c, there are no reasons to show this internal stuff
78 Affected files are silcd/serverconfig.[ch].
80 * Added macro SILC_SERVER_LOG_STDERR(), this should replace most
81 fprintf's to stderr, since some code may be executed again after
82 the server went into the background. Affected files are
85 * Added rehash support. Added function silc_server_rehash() that
86 will perform all the basic tasks of the rehashing procedure.
88 * Added command line option `-x, --hexdump'. This will enable the
89 SILC_LOG_HEXDUMP calls that are no longer enabled with `--debug'.
90 The option `--hexdump' implies `--debug'.
92 * Fixed a bad bug in the logging APIs (silcutil library) where
93 the application would crash after calling silc_log_reset_all().
95 Wed Mar 27 19:43:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
97 * Fixed the KICKED notify handling in client library to
98 correctly remove the channel and all entries from the
99 channel when I was kicked. This bug crashed the client.
101 Fixed yet another but in KICKED notify handling to remove
102 the kicked client correctly from the channel.
104 Affected file is lib/silcclient/client_notify.c.
106 * Fixed a minor bug in looking up correct client entry
107 in KICKED notify in server. Affected file is
108 silcd/packet_receive.c.
110 * Fixed the lib/silcmath/Makefile.am to include the MPI and GMP
111 sources correctly to distribution. Fixes --with-gmp option.
113 * Removed the manual rehashing from ID Cache, and changed it
114 to use the SILC Hash Table's auto rehash feature. Affected
115 file is lib/silccore/silcidcache.c.
117 Wed Mar 27 00:07:11 EET 2002 Pekka Riikonen <priikone@silcnet.org>
119 * Fixed a bug in the silc_client_nickname_format function that
120 handles the multiple same nickname formatting. Two clients
121 with same nickname caused problems after the first one left
122 and rejoined. It didn't format the nickname correctly.
123 Affected file is lib/silcclient/idlist.c.
125 Tue Mar 26 19:33:03 CET 2002 Pekka Riikonen <priikone@silcnet.org>
127 * Don't change the topic if olod topic is same as new one.
128 Affected file is silcd/packet_receive.c.
130 Mon Mar 25 21:11:35 EET 2002 Pekka Riikonen <priikone@silcnet.org>
132 * Added cross-reference support to the SILC Documentation
133 generator. All types across all HTML files are now cross-
134 referenced. Affected files util/robodoc/generator.c and
135 scripts/silcdoc/silcdoc.
137 * Added file lib/silcutil/silctypes.h to include all the
138 arithmetic type definitions and some macros. Removed
139 includes/bitmove.h and moved macros to silctypes.h.
141 Mon Mar 25 17:19:46 EET 2002 Pekka Riikonen <priikone@silcnet.org>
143 * Merged bugfixes for Irssi SILC client from irssi.org CVS.
145 Sun Mar 24 11:21:04 EET 2002 Pekka Riikonen <priikone@silcnet.org>
147 * Added `type' argument to silc_id_payload_parse_id function which
148 now returns the type of the ID to the sent pointer. Affected
149 file is lib/silccore/silcid.[ch].
151 * Added check for CMODE_CHANGE notify type that mode change is
152 allowed by the sender. Affected file silcd/packet_receive.c.
154 * Added check for CUMODE_CHANGE notify type that mode change is
155 allowed by the sender. Affected file silcd/packet_receive.c.
156 Added the ID type as CUMODE_CHANGE notify type as argument
157 to the `notify' client operation. Affected files are
158 lib/silcclient/client_notify.c, irssi/src/silc/core/client_ops.c.
160 * Added function silc_client_add_server to the client library.
161 Added support for resolving also channel and server info when
162 received unknown entity in notify packet. Affected files are
163 lib/silcclient/idlist.[ch], lib/silcclient/client_notify.c.
165 * Added function silc_command_get_status to return the command
166 status from the command reply's argument payload. Affected files
167 are lib/silccore/silccommand.[ch].
169 * Added check for KICKED notify type that the kicking is
170 allowed by the client. Affected file silcd/packet_receive.c.
172 * Created function silc_get_input which can be used to get input
173 (echo on or off) from user on command line. Affected files are
174 lib/silcutil/silcutil.[ch].
176 Sat Mar 23 09:51:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
178 * Optimized silc_server_packet_relay_to_channel function.
179 Added new function silc_channel_message_payload_encrypt which
180 can be called directly if channel message payload needs to
181 be encrypted and is already encoded (no need to call _encode
182 function). Packet relaying is now done by router without any
183 extra memory allocations. Affected files are
184 lib/silccore/silcchanel.[ch], silcd/packet_receive.c and
187 * Fixed the INVITE notify handling. It took wrong arguments
188 as invite list and invite delete. Affected file is
189 silcd/packet_receive.c.
191 * Added check for TOPIC_SET notify type that the topic change is
192 allowed by the client. Affected file silcd/packet_receive.c.
194 * Added check for INVITE notify type that inviting is allowed by
195 the client. Affected file silcd/packet_receive.c.
197 * Changed the silc_server_client_on_channel to return the
198 SilcChannelClientEntry as well. Moved the function
199 silc_server_check_cmode_rights to server_util.[ch].
200 Affected files are silcd/server_util.[ch], silcd/command.c.
202 * Added function silc_server_check_umode_rights to check whether
203 changing client's user mode is allowed. Added check for
204 UMODE_CHANGE notify type that the umode change is allowed
205 by the client. Affected files are silcd/server_util.[ch],
206 silcd/packet_receive.c and silcd/command.c.
208 Fri Mar 22 12:25:58 CET 2002 Pekka Riikonen <priikone@silcnet.org>
210 * Fixed the SILC_PACKET_MAX_ID_LEN to actually be the max
211 ID length. It ignored that ID can be IPv6 based as well.
212 Affected file lib/silccore/silcpacket.h.
214 * Fixed the silc_id_id2str and silc_id_str2id to take the
215 IPv6 address offset's into consideration. Affecte file is
216 lib/silccore/silcid.c.
218 Thu Mar 21 20:44:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
220 * Fixed the internal Unix scheduler functions to check for
221 NULL context they may receive. The affected file is
222 lib/silcutil/unix/silcunixschedule.c.
224 Thu Mar 21 19:12:22 EET 2002 Timo Sirainen <tss@iki.fi>
226 * Changed hardcoded ~/.silc paths to use get_irssi_dir() so you
227 can specify different directory with --home command line
228 parameter. Affected files irssi/src/silc/core/client_ops.c,
231 * SILC-specific commands aren't now executed if the active server
232 isn't of SILC-type, so there won't be problems with having
233 IRC and SILC protocol support in same client. Affected files
234 irssi/src/silc/core/silc-channels.c, silc-servers.c,
237 Wed Mar 20 11:06:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
239 * Improved the signal support in SILC Schedule. Added new
240 function silc_schedule_signal_call which is used by application
241 to mark a signal to be called. It is now safe to perform
242 any kind of tasks in signal callbacks since it is guaranteed
243 that the application specified signal callback is called
244 after the signal is over. Affected files are
245 lib/silcutil/silcschedule.[ch], lib/silcutil/*/silc*schedule.c.
247 Tue Mar 19 20:42:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
249 * Added `name' field to SilcChannelPrivateKey to represent
250 application given name for the key. Moved also the context from
251 lib/silcclient/idlist.h into lib/silcclient/silcclient.h.
252 Added the `name' argument also to the function
253 silc_client_add_channel_private_key.
255 Added function silc_client_current_channel_private_key to set the
256 current channel private key in use.
258 Added "change" command to KEY command which can be used to change
259 the current channel private key. Bound the command also to
262 Also affected files lib/silcclient/client_channel.c,
263 irssi/src/docs/help/in/key.in, irssi/src/silc/core/silc-channel.c.
265 Tue Mar 19 16:32:43 CET 2002 Pekka Riikonen <priikone@silcnet.org>
267 * Added silc_rng_get_byte_fast function in to the
268 lib/silccrypt/silcrng.[ch].
270 * Changed the interface of silc_packet_assemble and the
271 silc_packet_send_prepare. If silc_packet_assmble is now
272 called the application does not call silc_packet_send_prepare
273 because the library will call it automatically. These
274 interfaces now also return a reference to the outgoing buffer
275 which includes the assembled packet, which the application can
276 use to encrypt the packet.
278 Affected files are lib/silccore/silcpacket.[ch],
279 lib/silcclient/client.c, client_channel.c client_prvmsg.c,
280 silcd/packet_send.c, server_backup.c and packet_receive.c.
282 * Fixed a packet sending bug on very high load, where outgoing
283 packet queue wasn't handled correctly and packets got corrupted.
284 Affected files are lib/silcutil/*/silc*sockconn.c,
285 lib/silcclient/client.c and silcd/server.c.
287 Mon Mar 18 21:00:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
289 * Added macro SILC_PACKET_DATALEN which can be used during
290 packet assembling to check whether the data to be added to
291 the packet will fit to SILC_PACKET_MAX_LEN. If not the data
292 len is truncated until it fits it.
294 Added checks for maximum length of channel message payload and
295 private message payload also.
297 Added checks for maximum packet length in server and in
300 Affected files are lib/silccore/silcpacket.h, silcd/packet_send.c,
301 lib/silcclient/client.c, lib/silccore/silcchannel.c and
302 lib/silccore/silcprivate.c, lib/silcclient/client_channel.c and
303 lib/silcclient/client_prvmsg.c.
305 Mon Mar 18 14:54:42 CET 2002 Pekka Riikonen <priikone@silcnet.org>
307 * Added silc_server_packet_queue_purge call to the
308 silc_server_disconnect_remote to assure that all data in the
309 queue before disconnecting is sent to the network. Affected
312 Sun Mar 17 19:26:16 EET 2002 Pekka Riikonen <priikone@silcnet.org>
314 * Added the deleting of server's own ID cache entry to the
315 silc_server_free function. Free also everything else that
316 has been allocated in silc_server_init. The affected file
319 Sun Mar 17 15:44:56 EET 2002 Pekka Riikonen <priikone@silcnet.org>
321 * Added functions silc_parse_version_string, silc_version_to_num,
322 and silc_ske_parse_version to parse SILC protocol style version
323 strings. Affected files lib/silcutil/silcutil.[ch] and
324 lib/silcske/silcske.[ch].
326 * Added new configuration params: version_protocol, version_software
327 and version_software_vendor to specify what version the remote
328 host must at least be to be able to connect to server. The vendor
329 string can be regex matched too. Added new function
330 silc_server_connection_allowed to check maximum number of allowed
331 connections, and allowed versions for incoming connections.
332 Affected files are silcd/server.c, server_util.[ch] and
335 Sun Mar 17 10:24:50 EET 2002 Pekka Riikonen <priikone@silcnet.org>
337 * Added preliminary support for signals in scheduler. The
338 signals we care about are now blocked always when the scheduler
339 is locked. This way we can synchronise the use of signal with
340 scheduler. It is guaranteed that when signal occurs the scheduler
341 is not locked, and thus new tasks can be safely added to the
344 Renamed silc_schedule_wakeup_init and silc_schedule_wakeup_uninit
345 to silc_schedule_internal_init and silc_schedule_internal_uninit.
346 Added new platform specific routines
347 silc_schedule_internal_signals_[un]block and
348 silc_schedule_internal_signal_[un]register.
350 Added new functions to SILC Schedule API:
351 silc_schedule_signal_[un]register. Each signal that application
352 is going to use should be registered to the scheduler.
354 Affected files are lib/silcutil/silcschedule.[ch],
355 lib/silcutil/*/silc*schedule.c.
357 Sat Mar 16 22:39:23 EET 2002 Pekka Riikonen <priikone@silcnet.org>
359 * Check for unauthenticated client and server in the
360 silc_server_new_client and silc_server_new_server functions.
361 Affected file silcd/packet_receive.c.
363 * Added function silc_string_is_ascii to check whether given
364 string is 7-bit ASCII string. Affected files are
365 lib/silcutil/silcutil.[ch].
367 * Added function silc_id_is_valid_server_id into the
368 silcd/serverid.c and added checking for valid Server ID's in
369 silc_server_new_server. The Server ID must always be based
370 on the server's public IP address.
372 * Added logging of DISCONNECT packet message in the server.
373 Affected file silcd/server.c.
375 Sat Mar 16 18:04:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
377 * Changed all library interfaces that use Global RNG to also
378 accept SilcRng as argument. Affected files are
379 lib/silcclient/command.c, lib/silccore/silcauth.[ch],
380 lib/silccore/silcchanel.[ch], lib/silcclient/client_channel.c,
381 silcd/packet_send.c, lib/silccore/silcprivate.[ch],
382 lib/silcmath/silcprimegen.c, lib/silcmath/silcmath.h, and
385 * Added function silc_pkcs_generate_key to the
386 lib/silccrypt/silcpkcs.[ch] for applications so that they
387 don't need to do pkcs->pkcs->init calls anymore.
389 * Remove SilcSocketConnection from the SFTP API since it really
390 wasn't needed there. The application has the information
391 saved in its contexts anyway and the SFTP layer doesn't need
392 know about it. Affected files lib/silcsft/silcsftp.h and
393 lib/silcsftp/sftp_[server/client].c.
395 * Rewrote the SILC SIM (modules) interface in lib/silcsim.[ch].
396 The SilcSimContext is not SilcSim.
398 * Fixed possible buffer overflows in silc_id_render in the
399 lib/silcutil/silcutil.c.
401 * On EPOC the global crypto module lists are not used at all
402 in the crypto library. Added support for using the constant
403 algorithm list on EPOC. Affected files are
404 lib/silccrypt/silccipher.c, silchash.c, silchmac.c and
407 * Fixed the handling of third parameter of KICKED notify, since
408 it was mistakenly updated to SILC Protocol 1.0 even though it
409 is to be included in 1.1. Since it is not in 1.0 it is not
410 mandatory, and this fix now handles it only if it is provided,
411 and it is not error if it is not provided. Affected file
412 lib/silcclient/client_notify.c.
414 Sat Mar 16 09:07:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
416 * Handled CHANNEL_CHANGE notify (ignore it) in Irssi SILC
417 client. Affected file irssi/src/silc/core/client_ops.c.
419 * Merged with Irssi 0.8.4 from irssi.org CVS.
421 Thu Mar 14 12:53:57 CET 2002 Pekka Riikonen <priikone@silcnet.org>
423 * Check for valid socket connection in client entries before
424 sending any messages. Fixes a crash, but doesn't fix some
425 other underlaying bug that is lurking there. Affected
426 file silcd/packet_send.c.
428 Thu Mar 14 13:38:12 EET 2002 Timo Sirainen <tss@iki.fi>
430 * $usermode, $cumode and $cumode_space expandos shouldn't do
431 anything with non-SILC server records. Affected file
432 irssi/src/silc/core/silc-expandos.c
434 Wed Mar 13 21:38:26 EET 2002 Pekka Riikonen <priikone@silcnet.org>
436 * Fixed the silc_net_check_[host/local]_by_sock to support
437 IPv6 bound sockets as well. Now they can return IPv6 addresses
438 as well. Affected file lib/silcutil/silcnet.c.
440 * Fixed silc_net_addr2bin to correctly convert IPv6 addresses.
441 Affected lib/silcutil/unix/silcunixnet.c.
443 * Fixed ID rendering (at least on some platforms, not NetBSD)
444 for IPv6 addresses. Affected file lib/silcutil/silcutil.c.
446 Tue Mar 12 17:58:59 EET 2002 Pekka Riikonen <priikone@silcnet.org>
448 * Added silc_hash_public_key and silc_hash_public_key_compare
449 functions to be used with SilcHashTable. They can be used to
450 hash public keys and compare public keys in hash table. Affected
451 file lib/silcutil/silcutil.[ch].
453 * Added support for specifying multiple public keys for Client
454 connection section in server configuration file. This makes it
455 possible to accept multiple public keys from same host, or to
456 make a section that accepts any incoming host, and have the
457 accepted public keys listed in the section.
459 Added functions silc_sever_[find/get]_public_key, added the
460 support for this actually to all connection sections but only
461 the Client section is currently allowed to specify multiple
464 Affected files are silcd/server.c, server_internal.h,
465 command.c, protocol.c, server_util.[ch], packet_receive.c.
467 Mon Mar 11 23:37:38 EET 2002 Pekka Riikonen <priikone@silcnet.org>
469 * Merged Irssi 0.8.2 from irssi.org CVS.
471 Sun Mar 10 23:34:48 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
473 * If silc_debug is TRUE, also output standard logging messages
474 to stderr with the debug output.
476 Made silc_log_reset_all() flushing all channels before returning.
477 Also fixed some documentation typos.
479 Affected files are lib/silcutil/silclog.[ch].
481 Sun Mar 10 20:07:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>
483 * Fixed the server to check correctly the amount of connections
484 from single host, by checking also the type of the connection.
485 Fixed also the comparison of number of connections and number
486 of allowed connections. Affected files are silcd/server.c,
489 Fri Mar 8 17:16:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
491 * Fixed the USERS command reply to save the user's mode on the
492 channel as well. Fixed JOIN command reply to check whether a
493 client is on channel already and not join it twice. Affected
494 file lib/silcclient/command_reply.c.
496 * Added new file silc-expandos.c into irssi/silc/core/ to return
497 various stuff for various signal for the statusbar etc. updating.
498 Now Irssi SILC client prints channel user modes etc. on the
501 * The user mode (like server/router operator changes) is now shown
502 on the Irssi SILC client's statusbar. The affected files are
503 irssi/src/silc/core/client_ops.c, silc-expandos.c.
505 Thu Mar 7 19:21:22 EET 2002 Pekka Riikonen <priikone@silcnet.org>
507 * Changed silc_mutex_[un]lock calls in lib/silcutil/silcschedule.c
508 to SILC_SCHEDULE_[UN]LOCK macros.
510 * Added more error printing to logs in server code. Affected
511 files silcd/server.c and silcd/protocol.c.
513 * Fixed -S option parsing in Irssi SILC Client. Affected file
514 irssi/src/silc/core/silc-core.c.
516 * Added silc_buffer_alloc_size function. Affected file is
517 lib/silcutil/silcbuffer.h.
519 Tue Mar 5 14:37:27 EET 2002 Pekka Riikonen <priikone@silcnet.org>
521 * Changed all silc_[hash|hmac|cipher|pkcs]_default tables to
522 constants. Affected files in
523 lib/silccrypt/silcpkcs.[ch], silchash.[ch], silchmac.[ch] and
526 * Changed the internal SFTP Memory FS table to const. Affected
527 file lib/silcsftp/sftp_fs_memory.c.
529 Sun Mar 3 18:37:13 EET 2002 Pekka Riikonen <priikone@silcnet.org>
531 * Fixed the buffer formatting and unformatting routines to

546 Sat Feb 23 20:31:43 EET 2002 Pekka Riikonen <priikone@silcnet.org>
548 * Added `prefer_ipv6' argument to the functions
549 silc_net_gethostbyname[_async]. If it is TRUE it will return
550 IPv6 address over IPv4. If FALSE IPv4 address is returned
551 even if IPv6 address was found. Affected files
552 lib/silcutil/silcnet.[ch].
554 * Added support silc_net_create_connection[_async] to fallback
555 to IPv4 address if IPv6 address could not be used (like if

568 application does not need to define them. Affected file
569 includes/silcincludes.h.
571 * Renamed lib/silcclient/silcapi.h to silcclient.h as the
572 old name went against naming convention. Applications now
573 include "silcclient.h" instead of "clientlibincludes.h".
574 Removed includes/clientlibincludes.h, it is redundant now.
576 * Renamed includes/version.h to silcversion.h.
578 * Added really preliminary support for OS/2 into the util
579 library. Only thread & mutex API is implemented, others
580 are still to be implemented. Created the lib/silcutil/os2/
581 directory. Created also file includes/silcos2.h.
583 Wed Feb 20 18:48:49 EET 2002 Pekka Riikonen <priikone@silcnet.org>

614 * Added `user_count' to the SilcChannelEntry which now tells the
615 number of users on the channel. The user count is now saved
616 in normal server of global channels as well. Affected files
617 silcd/server.c, idlist.h, packet_receive.c and command.c.
619 * Splitted lib/silcutil/silcutil.[ch] into silcfileutil.[ch] to

631 Affected file lib/silcclient/client.c.
633 Sun Feb 17 10:10:14 EET 2002 Pekka Riikonen <priikone@silcnet.org>
635 * ROBOdoc documented the lib/silcske/silcske.h, and improved
636 the SKE interface a bit.
638 * Fixed padding problem in PKCS#1. The padding was not actually
639 random since the random number generator was used incorrectly.
640 This security bug affects only when encrypting with PKCS#1, and
641 it is not currently used at all in SILC. SILC only use signing
642 with PKCS#1. Affected file lib/silccrypt/pkcs1.c.
644 Sat Feb 16 13:44:24 EET 2002 Pekka Riikonen <priikone@silcnet.org>

710 * Added new configuration options and blocks:
711 keepalive_secs, reconnect_count, reconnect_interval,
712 reconnect_interval_max, reconnect_keep_trying and
713 require_reverser_lookup. Added ConnectionParam block, and
714 implemented the connection parameters when connecting as
715 initiator and when accepting connections as responder.

720 Affected files silcd/serverconfig.[c], server.[c].
722 * Splitted the doc/example_silcd.conf.in. Separated the crypto
723 algorithm parts and created new file silcalgs.conf, that
724 is now included from the example_silcd.conf.in.
726 * Optimized the silc_server_connect_to_router_second to take
727 the connection configuration object from the SilcServerConnection
728 object instead of finding it during the connecting phase.
729 Added the configuration object to SilcServerConnection struct.
730 Affected files silcd/server_internal.h, server.c.

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

814 * Fixed the file transfer's key agreement payload to include
815 zero port also if the hostname is NULL because it could not
818 Call file transfer monitor callback now also if error occurs
819 during key agreement protocol.
821 Changed the silc_client_file_send interface to return the
822 SilcClientFileError instead of session id. The session ID
823 is returned into pointer provided as argument.

842 * Fixed the channel message payload decryption in the function
843 silc_channel_message_payload_decrypt to not modify the original
844 buffer before it is verified that the message decrypted
845 correctly. Otherwise, next time it is called with correct
846 channel key it won't encrypt since the payload is corrupted.
847 Affected file lib/silccore/silcchannel.c.
849 Sun Feb 3 11:46:12 EET 2002 Pekka Riikonen <priikone@silcnet.org>

863 become invalid in the callback but it was referenced after
864 the callback returned.
866 Do not allow auto rehashing of hash table during the
867 silc_hash_table_foreach operation, for same reasons as it is
868 not allowed for SilcHashTableList. Affected files are
869 lib/silcutil/silchashtable.[ch].

897 rehashed. It is now guaranteed that auto rehashable tables
898 are not rehashed while tarversing the list. Also defined that
899 silc_hash_table_rehash must not be called while tarversing
900 the table. Added function silc_hash_table_list_reset that must
901 be called after the tarversing is over. The affected files are
902 lib/silcutil/silchashtable.[ch].
904 * Changed all hash table traversing to call the new
905 silc_hash_table_list_reset in server and in client library.
907 * Added function silc_client_on_channel to return the
908 SilcChannelUser entry if the specified client entry is joined

928 * Create the key in JOIN command of the router did not return
929 the channel key, added check for this. Affected file is
932 * Fixed a channel ID update bug in JOIN command reply. Do
933 not directly upgrade the ID but call the function
934 silc_idlist_replace_channel_id if the ID was changed.
935 Affected file silcd/command_reply.c.
937 * Fixed memory leaks from command calling if it would fail.
938 Affected file silcd/command.c.

965 functions. Affected file silcd/server.c.
967 * Fixed the CHANNEL_CHANGE notify to re-announce the channel
968 which ID was changed. This way the router will send the
969 user list for the channel again, and server won't be in
970 desync in some rare circumstances. Affected file is
971 silcd/packet_receive.c.
973 Sun Jan 27 21:04:19 EET 2002 Pekka Riikonen <priikone@silcnet.org>

1084 online. Affected file silcd/server_util.c.
1086 * Added `sock_error' field into the SilcSocketConnection
1087 context. When error occurs during socket operation (read
1088 or write) the error is saved. Added also new function
1089 silc_socket_get_error to return human readable socket error
1090 message. Affected files are lib/silcutil/silcsockconn.[ch],
1091 lib/silcutil/unix/silcunixsockconn.c, and
1092 lib/silcutil/win32/silcwin32sockconn.c.
1094 * The server now prints the socket error message in the
1095 signoff for client. Affected file silcd/server.c.
1097 * Fixed the `created' channel information sending from router
1098 to server in JOIN command. Checks now whether the channel
1099 really was created or not and set it according that.
1101 Fixed the JOIN command to use the client entry's current
1102 ID during the joining procedure instead of the one it sent
1103 in the command (it is checked though), since it can change
1104 between the packet processing and command processing, and
1105 would just case unnecessary pain in the client end. Affected
1106 file silcd/command.c.
1108 * Fixed a channel key payload sending to use correct channel
1109 ID when the server was forced to change the channel's ID by
1110 router. Router sent the key payload with the old Channel ID.
1111 Affected file silcd/packet_receive.c.
1113 Wed Jan 16 22:26:30 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1115 * Call silc_server_save_channel_key only if the key payload
1116 was provided in the JOIN command's command reply. Affected
1117 file silcd/command_reply.c.
1119 Tue Jan 15 18:49:41 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1121 * Fixed silc_mp_sizeinbase to return the value correctly with
1122 MPI. Affected file lib/silcmath/mp_mpi.c.
1124 * Fixed the stop_server signal to correctly stop the scheduler
1125 and gracefully stop the server when SIGTERM or SIGINT signals
1126 are received. Affected file silcd/silcd.c.
1128 Mon Jan 7 23:38:19 CET 2002 Johnny Mnemonic <johnny@themnemonic.org>
1130 * Simple handling of TERM and HUP signals. Also added some log
1131 flushing call around. Affected file is
1134 * Fixed small bugs in silclog.c. Now buffering output will take
1135 effect after 10 seconds since startup: This will ensure that
1136 no important startup messages are lost. Also output redirection
1137 will preserve original format ([Date] [Type] message).
1138 Affected file is lib/silcutil/silclog.c.
1140 * Added two options to the config file, in the logging section:
1141 quicklogs:<yes/no>: and flushdelay:<seconds>:. Affected files
1142 lib/silcutil/silclog.[ch], silcd/serverconfig.[ch].
1144 Sun Jan 6 12:49:40 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1146 * Do not print the warning about log files not being initialized
1147 more than once to avoid excess logging. Affected file is
1148 lib/silcutil/silclog.c.
1150 * Fixed the SIM compilation in lib/silcsim/Makefile.am. Fixed
1151 the SIM copying in make install in Makefile.am.pre.
1153 Sun Jan 6 01:10:21 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1155 * Rewritten silclog APIs. Globally interesting changes follows:
1156 silc_log_set_files() changed to silc_log_set_file().
1157 silc_log_set_callbacks() changed to silc_log_set_callback().
1158 ROBOdoc documented silclog header file.
1159 SilcLogCb now returns bool to wether inihibit the default
1160 handler or not (to keep the old behaviour return always TRUE).
1161 The new APIs should also fix the problem of the
1162 silcd_error.log file that was written in the current directory.
1165 Log files streams will remain opened after silc_log_set_file()
1166 call, means less CPU usage notably on high traffic servers.
1167 File streams are now full buffered, and flushed to the disk
1168 every 5 minutes, lesses HD activity and CPU usage.
1169 Messages can be redirected, allowing admins to configure
1170 one single logfile for all server messages.
1171 the silc_log_quick global variable to activate fast-logging.
1172 Affected files lib/silcutil/silclog.[ch]
1174 * Changed some code to conform new silclog APIs. Affected
1175 files are doc/example_silcd.conf.in, silcd/server.c
1176 irssi/src/silc/core/silc-core.c, silcd/serverconfig.[ch],
1179 * Fixed a memory leak that could occur in some situations.
1180 Affected file silcd/serverconfig.c.
1182 Sat Jan 5 13:37:29 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1184 * Added the silc_client_del_client to remove the client from
1185 all channels as well. Affected file lib/silcclient/idlist.c.
1187 * Fixed the client library to correctly remove the client
1188 from all channels when the client entry is being destroyed.
1189 Affected file lib/silcclient/client_notify.c, command.c.
1191 * Added auto-nicking support to the client library. If the
1192 applicatio now sets client->nickname it will be sent to the
1193 server after connecting by the library. This way for example
1194 SILCNICK (or IRCNICK) environment variables will have effect
1195 and always change the nickname automatically to whatever
1196 it is wanted. Affected file lib/silcclient/client.[ch].
1198 * Renamed silc_server_command_bad_chars to the
1199 silc_server_name_bad_chars and moved it to the
1200 silcd/server_util.[ch]. Added also new function
1201 silc_server_name_modify_bad to return nickname that
1202 includes bad characters as new nickname without those
1203 bad characters. This check and modify is now used in
1204 silc_server_new_client when the username is initially set
1205 as nickname, so it must be checked to be valid nickname.
1206 Affected file silcd/packet_receive.c.
1208 * The nickname length is now taken from the packet for real
1209 and not trusted to strlen() since it clearly can return
1210 wrong length for nickname including bad characters. This
1211 also applies to channel names. Affected file silcd/command.c.
1213 * Removed the lib/silcsilm/modules directory. Modules are now
1214 compiled into the lib/silcsim. Fixed the copying of the
1215 modules to follow symbolic links in Makefile.am.pre.
1217 Wed Jan 2 18:56:21 EET 2002 Pekka Riikonen <priikone@silcnet.org>
1219 * Fixed silc_string_regexify list creation. Fixes bugs with
1220 BAN and INVITE commands in server. The affected file is
1221 lib/silcutil/unix/silcunixutil.c.
1223 Sun Dec 30 13:41:34 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1225 * Removed the command destructor entirely from the server's
1226 command and command reply routines. It is not needed, and
1227 its usage was buggy and caused crashes. Affected files are
1228 silcd/command[_reply].[ch].
1230 Fri Dec 28 12:43:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1232 * Cancel protocol and NULL sock->protocol if timeout
1233 occurred during protocol. Affected file silcd/server.c.
1235 * Cancel protocol timeouts always before calling the final
1236 callback, to assure that after final callback is called
1237 no other state will be called for the protocol anymore.
1238 Affected file silcd/protocol.c.
1240 * Print error log if incoming connection configuration could
1241 not be found. Affected file silcd/server.c.
1243 * Fixed JOIN command to correctly save the founder mode
1244 to the client on normal SILC server, when the channel
1245 was created by the router. Affected file silcd/command.c.
1247 * Fixed LIST command (hopefully) to send correct reply
1248 packets. Affected file silcd/command.c.
1250 Thu Dec 20 16:14:52 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1252 * The silc_packet_receive_process now returns FALSE if the
1253 read data was invalid packet, and TRUE if it was ok.
1255 The server now checks that if unauthenticated connection
1256 sends data and its processing fails the server will close
1257 the connection since it could be a malicious flooder.
1259 Affected files lib/silccore/silcpacket.[ch], silcd/server.c.
1261 Wed Dec 19 21:31:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1263 * Make sure the warning about error opening a log file is
1264 printed only once and not everytime it fails (produces
1265 too much useless log). Affected file lib/silcutil/silclog.c.
1267 Wed Dec 19 18:21:51 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1269 * Made the silc_server_daemonise() function more readable.
1270 Affected file silcd/server.c.
1272 * Pid file is now optional, the user may comment it out from
1273 the config file. Removed define SILC_SERVER_PID_FILE, we
1274 don't need a default any longer. Affected file
1275 configure.in.pre, lib/Makefile.am.pre.
1277 * Make some use of the pid file. The server now dies at startup
1278 if it detects a valid pid file on his path. The server would
1279 die anyway in this circumstance, because of the bind() failure.
1280 Affected file silcd/silcd.c.
1282 * No longer compiling lib/dotconf.
1284 Mon Dec 17 18:24:27 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1286 * Fixed JOIN command parsing not to crash. Affected file
1287 lib/silcclient/command.c.
1289 * Fied the NICK_CHANGE notify to add the new client entry
1290 even it is resolved. This removes an <[unknown]> nick
1291 thingy bug in the client. Affected file is
1292 lib/silcclient/client_notify.c.
1294 * Do not try to allocate 0 bytes (efence does not like it)
1295 in lib/silccore/silccomand.c when encoding payload.
1297 * Do not take IRCNICK as nickname in Irssi SILC client since
1298 it is not possible to set nickname before hand connecting
1299 the server (TODO has an entry about adding auto-nicking
1302 * Changed the silc_server_command_pending to check whether
1303 there already exists an pending entry with the specified
1304 command, command identifier and pending callback. This is
1305 to fix IDENTIFY and WHOIS related crashes that may register
1306 multiple pending commands with same identifier. Affected
1307 file silcd/command.c.
1309 * Fixed the server to reconnect to the router even if it
1310 was already reconnecting and EOF was received. This to
1311 fix a possibility that the server wouldn't ever try to
1312 auto-reconnect to the router. Affected file silcd/server.c.
1314 Sat Dec 15 20:31:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1316 * Fixed the server's password authentication to use the
1317 length of the locally saved password, and not the one
1318 sent in the packet. Affected file silcd/protocol.c.
1320 * Fixed same password authentication problem in the
1321 Authentication Payload handling routines in
1322 lib/silccore/silcauth.c.
1324 * Yet another password authentication problem fixed with
1325 channel password handling in silcd/command.c.
1327 Mon Dec 10 19:57:40 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1329 * If first character of string in silc_parse_userfqdn is '@'
1330 then do not parse it. Affected file is
1331 lib/silcutil/silcutil.c.
1333 Sun Dec 9 22:18:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1335 * Fixed minor bug in IDENTIFY command reply sending, which
1336 caused various weird problems during JOIN when it was
1337 resolving names for users. Affected file silcd/command.c.
1339 Sun Dec 9 19:18:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1341 * Fixed the IDENTIFY command reply sending to chech better valid
1342 clients. It was possible to send incomplete list of replies.
1343 Affected file silcd/command.c.
1345 Sat Dec 8 15:58:31 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1347 * Added silc_client_command[s]_[un]register functions now to
1348 dynamically register the commands in client library. Removed
1349 the static table of commands. This allows the client library
1350 to call commands without causing the application to know about
1351 what commands library has called.
1353 Removed the INFO command reply kludge to detect when the command
1354 was called by library. Now library use its own command reply
1355 function for INFO command.
1357 Added function silc_client_command_call to call a command.
1358 Application can use it to call command, not access the structure
1361 Now all commands that are sent by the client library (not
1362 explicitly sent by application) use own command reply functions.
1364 Affected files around lib/silcclient/ and in
1365 irssi/src/silc/core/.
1367 * Fixed the WHOIS command reply sending to chech better valid
1368 clients. It was possible to send incomplete list of replies.
1370 Fixed the WHOIS and IDENTIFY to send the request to router
1371 if normal server did not do it and did not find any results.
1373 Affected file silcd/command.c.
1375 Thu Dec 6 17:21:06 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1377 * Moved the internal data from SilcClient context into its
1378 own file, not accesible to application. Affected files
1379 lib/silcclient/client.h and lib/silcclient/client_internal.h,
1380 and other files in client library.
1382 Thu Dec 6 10:37:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1384 * Added doc/examples installation target in Makefile.am.pre.
1387 Tue Dec 4 17:43:19 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1389 * If NO_SUCH_CLIENT_ID notify is received for WHOIS or IDENTIFY
1390 commands the found client entry will be removed from the
1391 cache, after notifying application about the error. Affected
1392 file lib/silcclient/command_reply.c.
1394 * Changed the /MSG to check for exact nickname user gave, and
1395 not let `nick' match `nick@host' if it is only one found. Now,
1396 user must type the exact nickname (like nick@host2) even if
1397 there are no more than one same nicks found. This is to avoid
1398 a possibility of sending nickname to wrong nickname since
1399 `nick' could match `nick@host'. Affected file is
1400 irssi/src/core/silc-servers.c.
1402 Mon Dec 3 18:49:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1404 * Do not print "you are now server operator" or similar when
1405 giving /away command. Affected files are
1406 irssi/src/silc/core/client_ops.c, silc-servers.h.
1408 * Made the silc_server_command_pending_error_check to send
1409 the same command reply payload it received back to the
1410 original sender of the command. This way all arguments
1411 that was received by the server will be received by the
1412 client too. Affected file silcd/command.c.
1414 * Added the silc_idcache_add to return the created cache entry
1415 to a pointer. Affected file lib/silccore/silcidcache.[ch].
1417 * Add global clients to expire if they are not on any channel.
1418 This is because normal server will never know if they signoff
1419 if they are not on any channel. The cache expiry will take
1420 case of these entries. This is done by normal servers only.
1421 The affected files are silcd/command_reply.c,
1422 silcd/idlist.[ch], silcd/server and silcd/packet_receive.c.
1424 * If server receives invalid ID notification for WHOIS or
1425 IDENTIFY and the ID exists in the lists, it is removed.
1426 Affected file silcd/command_reply.c.
1428 * If NO_SUCH_CLIENT_ID is received for WHOIS or IDENTIFY command
1429 in client then client entry that it matches is searched and
1430 the nickname is printed on the screen for user. Affected
1431 file irssi/src/silc/core/client_ops.c.
1433 Mon Dec 3 11:56:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1435 * Use cache entry expire time in the LIST command reply to
1436 purge old entries from the cache after the LIST command
1437 reply has been received. This way we don't have non-existent
1438 entries in the cache for too long. Affected file is
1439 silcd/command_reply.c.
1441 Sun Dec 2 23:29:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1443 * If we are normal server, and we've not resolved client info
1444 in WHOIS or IDENTIFY from router, and it is global client,
1445 we'll check whether it is on some channel. If it is not
1446 then we cannot be sure about its validity and will resolve it
1447 from router. Fixes a bug in WHOIS and IDENTIFY. Affected
1448 file silcd/command.c.
1450 * Search channel by name (if possible) rather than by ID
1451 in IDENTIFY command's command reply. Affected file is
1452 silcd/command_reply.c.
1454 Sun Dec 2 13:48:46 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1456 * Distribute to the channel passphrase in CMODE_CHANGE notify.
1457 Updated specs and implemented it. Affected file silcd/command.c,
1458 silcd/packet_send.c and silcd/packet_receive.c.
1460 * Implemented the <founder auth> payload handling in the JOIN
1461 command. If provided all conditions for channel joining
1462 except requirement to provide correct passphrase can be
1463 overrided by the channel founder. Updated the protocol specs.
1464 Affected file silcd/command.c.
1466 Added support for founder auth in JOIN command in client
1467 library. Fixed the parsing of the JOIN command now to support
1468 all options as they should be. The affected file is
1469 lib/silcclient/command.c.
1471 * Optimized the WHOIS and IDENTIFY commands to send the request
1472 to router only if it includes nicknames or other names. If
1473 they include only IDs then check the local cache first before
1474 routing. Affected file is silcd/command.c.
1476 * Added channels topic announcements. Affected file is
1477 silcd/packet_receive.c and silcd/server.c.
1479 * Fixed the silc_server_send_notify_topic_set to really destine
1480 the packet to channel. Affected file silcd/packet_send.c.
1482 * Fixed a crash in CHANNEL_CHANGE notify handling in the client
1483 library. Affected file lib/silcclient/client_notify.c.
1485 * Added UMODE announcements. Affected file silcd/server.c.
1487 Sat Dec 1 12:52:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1489 * Memory leak fixes in:
1491 lib/silcutil/silcsockconn.c
1492 lib/silcske/silcske.c
1493 lib/silcske/groups.c
1495 lib/silccrypt/silcpkcs.c
1496 lib/silccore/silccommand.c
1497 lib/silccore/silcidcache.c
1502 * ROBOdoc documented the lib/silcske/groups.h file and a
1503 bit changed the interface for better.
1505 Thu Nov 29 22:12:50 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1507 * Update the client entry context in the ID cache after
1508 nick change. Affected file lib/silcclient/command.c.
1509 Fixes the CUMODE command when regaining founder privileges,
1510 and a little WHOIS problem.
1512 * Fixed silc_net_gethostbyname to correctly call the
1513 inet_ntop. Affected file lib/silcutil/silcnet.c.
1515 Thu Nov 29 19:31:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1517 * Added IPv6 support checking to the configure.in.pre, added
1518 also --enable-ipv6 option to override the check. Affected
1519 file configure.in.pre.
1521 * The silc_thread_create now calls the start function
1522 directly if threads support is not compiled in. Removes
1523 ugly #ifdef's from generic code. Affected files are
1524 lib/silcutil/unix/silcunixthread, win32/silcwin32thread.c.
1526 * Added silc_net_gethostby[name/addr]_async to asynchronously
1527 resolve. Affected files are lib/silcutil/silcnet.[ch].
1529 * Added support for rendering IPv6 based server, client and
1530 channel IDs. Affected file lib/silcutil/silcutil.c.
1532 * Added support for creating IPv6 based server IDs. Affected
1533 file is silcd/serverid.c.
1535 Wed Nov 28 23:46:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1537 * Added silc_net_gethostby[addr/name] into the
1538 lib/silcutil/silcnet.[ch]. Added IPv6 support to Unix network
1539 routines. Added silc_net_is_ip[4/6]. Affected file is
1540 lib/silcutil/unix/silcunixnet.c. All routines that take
1541 address as argument now supports both IPv4 and IPv6 addresses.
1543 Mon Nov 26 18:09:48 EET 2001 Pekka Riikonen <priikone@silcnet.org>'
1545 * Fixed LIST command reply sending in server. Affected file
1548 * Server now sends the kicker's client ID in the KICK notify
1549 to the kicked client. Affected file silcd/command.c.
1551 * The client library now parses the kickers client ID and
1552 UI displays it. Affected files lib/silcclient/client_notify.c
1553 and irssi/src/silc/core/silc-channels.c, module-formats.c.
1555 * Made all payload parsing function prototypes consistent.
1556 They all take now const unsigned char * and uint32 pair as
1557 the payload data instead of SilcBuffer. Changes all around
1558 the source tree. Other unsigned char* -> const unsigned char*
1559 changes around the tree as well.
1561 * Optimized SFTP client and server packet sending not to
1562 allocate new buffer for each packet but to recycle the
1563 first allocated buffer. Affected files are
1564 lib/silcsftp/sftp_client.c, sftp_server.c, sftp_util.[ch].
1566 * Optimized the SFTP client to use SilcList instead of
1567 SilcDList for requests, because it is faster. Affected file
1568 is lib/silcsftp/sftp_client.c.
1570 * Moved the ID Payload routines from lib/silccore/silcpayload.[ch]
1571 into lib/silccore/silcid.[ch].
1573 Renamed silcpayload.[ch] into silcargument.[ch].
1575 Mon Nov 26 15:01:53 CET 2001 Pekka Riikonen <priikone@silcnet.org>
1577 * If client entry is deleted with active key agreement
1578 session, abort the session.
1580 The silc_client_abort_key_agreement now calls the completion
1581 callback with new SILC_KEY_AGREEMENT_ABORTED status.
1583 Affected file lib/silcclient/silcapi.h, client_keyagr.c and
1586 Sun Nov 25 18:01:45 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1588 * Don't use __restrict in older GCC's. Affected file is
1589 lib/silcmath/mpi/mpi-priv.h. A patch by salo.
1591 * silc_net_localhost now attempts to reverse lookup the
1592 IP/hostname. Affected file lib/silcutil/silcnet.c.
1594 * Defined <founder auth> argument to the SILC_COMMAND_JOIN
1595 command. It can be used to gain founder privileges at
1596 the same time when joining the channel.
1598 Defined that the SILC_NOTIFY_TYPE_KICKED send the
1599 kicker's client ID as well. Updated protocol specs.
1601 Defined that the server must send SILC_COMMAND_IDENTIFY
1602 command reply with error status to client who sent
1603 private message with invalid client ID.
1605 Updated the protocol specification.
1607 * Added silc_server_send_command_reply to send any
1608 command reply. Affected file silcd/packet_send.[ch].
1610 * Added silc_id_payload_encode_data to encode ID payload
1611 from raw ID data. Affected file lib/silccore/silcpayload.[ch].
1613 * The server now send IDENTIFY command reply with error
1614 status if client ID in private message is invalid. Affected
1615 file silcd/packet_receive.c.
1617 * Save the server key file with server's IP address in
1618 the filename instead of hostname. The affected file is
1619 irssi/src/silc/core/client_ops.c.
1621 Sat Nov 24 20:08:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1623 * Typo fixes in irssi/src/fe-common/silc/module-formats.c.
1626 * Added libtool support for compiling shared objects in
1627 lib/silcsim. Affected file configure.in.pre and
1628 lib/silcsim/Makefile.am. Original patch by cras.
1630 Fri Nov 23 23:30:59 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1632 * Pid file configuration, and server's config file fixes
1633 patch by toma. Updated CREDITS file.
1635 Sun Nov 18 01:34:41 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1637 * Fixed silc_client_channel_message to not try to decrypt
1638 the message twice if it resolved the destination client
1639 information. This could cause of dropping one channel
1640 message. Affected file lib/silcclient/client_channel.c.
1642 Wed Nov 14 23:44:56 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1644 * Added silc_client_run_one into lib/silcclient/silcapi.h and
1645 lib/silcclient/client.c. This function is used when the SILC
1646 Client is run under some other scheduler, or event loop or
1647 main loop. On GUI applications, for example this may be
1648 desired to used to run the client under the GUI application's
1649 main loop. Typically the GUI application would register an
1650 idle task that calls this function multiple times in a second
1651 to quickly process the SILC specific data.
1653 Wed Nov 14 19:16:52 CET 2001 Johnny Mnemonic <johnny@themnemonic.org>
1655 * Fixed silc_server_drop() for dropping the supplementary
1656 groups as well, this could cause a security hole on some
1659 Wed Nov 14 16:22:25 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1661 * __pid_t -> pid_t in lib/silccrypt/silcrng.c. A patch by
1664 * Write PID file after dropping privileges. Added -F option
1665 to run server on foreground. A patch by debolaz.
1666 Affected files silcd/server.c, silcd/silcd.c.
1668 * Fixed MOTD to return the MOTD file server name. Affected
1669 file silcd/command.c.
1671 * Added INFO command reply handling to the Irssi SILC Client.
1672 Affected file irssi/src/silc/core/client_ops.c.
1674 Wed Nov 14 00:18:08 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1676 * Fixed the silc_idcache_list_* routines to really support
1677 the dynamic list. Fixes a crash. Affected file is
1678 lib/silccore/silcidcache.c.
1680 * Fixed the LIST command reply to really call LIST command's
1681 pending callbacks. Affected file silcd/command_reply.c.
1683 Tue Nov 13 00:49:17 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1685 * Update conn->local_entry->nickname after giving NICK
1686 command. Affected file lib/silcclient/command.c.
1688 Sun Nov 11 23:43:02 PST 2001 Brian Costello <bc@wpfr.org>
1690 * Added the [pid] option to the silcd configuration file
1692 Affected files: serverconfig.[ch] and silcd.c
1694 Sun Nov 11 23:56:39 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1696 * Save fingerprint in WHOIS command reply in server.
1697 Affected file silcd/command_reply.c.
1699 * Fixed NICK commands pending callback registration.
1700 Affected file lib/silcclient/command.c.
1702 Sun Nov 11 10:49:10 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1704 * Use ++server->cmd_ident when sending commands in server,
1705 instead of random number. Affected file silcd/command.c.
1707 * Fixed GETKEY command reply to call actually GETKEY pending
1708 command callbacks. Affected file silcd/command_reply.c.
1710 * A bit stricter check for nicknames. Check for same nickname
1711 in NICK command also. Affected file silcd/command.c.
1713 * Do not call INFO command everytime client ID changes, only
1714 during first connecting. Affected file lib/silcclient/client.c.
1716 * Set the new nickname only after successful command reply for
1717 NICK command is returned by server. Affected file
1718 lib/silcclient/command.c.
1720 * Remove nicknames from nicklist during server_signoff notify.
1721 Should fix /NAMES bit more. The affected file is
1722 irssi/src/silc/core/silc-channels.c.
1724 * Added `fingerprint' field to the SilcIDListData in the
1725 silcd/idlist.h to hold the fingerprint of the client's
1728 Send the fingerprint of the client's public key in WHOIS
1731 Affected files silcd/command.c, and silcd/idlist.[ch].
1733 * Added silc_fingerprint into lib/silcutil/silcutil.[ch] to
1734 create fingerprint from given data.
1736 * Show the fingerprint of the client's public key in WHOIS.
1737 Affected files irssi/src/module-formats.[ch] and
1738 irssi/src/silc/core/client_ops.c.
1740 * Format the multiple same nicknames also during JOIN and
1741 NICK_CHANGE notifys. Affected file is
1742 lib/silcclient/client_notify.c.
1744 * Do not print error on screen for invalid private message
1745 payload since it can come if someone is sending private
1746 messages with wrong key. Affected file
1747 lib/silccore/silcprivate.c.
1749 * Fixed multiple concurrent /PING crash. Affected file
1750 lib/silcclient/command.c.
1752 * Changed the wrong ID encoding. All IP addresses must be
1753 in MSB first order in encoded format. They were encoded
1754 wrong and was in LSB format. Affected files are
1755 silcd/serverid.c, lib/silcutil/silcutil.c.
1757 * Remove silc_net_addr2bin_ne from lib/silcutil/silcnet.[ch].
1759 * Call the `connect' client operation through the scheduler
1760 in case of error. Affected file lib/silcclient/client.c.
1762 * Call the `failure' client operation even if the error
1763 occurred locally during a protocol. Affected file is
1764 lib/silcclient/protocol.c.
1766 * Added support of sending LIST command to router from normal
1767 server. This way normal server can get list of all channels
1768 in the network too. Fixed the channel list sending in the
1769 server too. Affected files are silcd/command.c, and
1770 silcd/command_reply.[ch].
1772 * Added silc_server_update_channels_by_server and
1773 silc_server_remove_channels_by_server. They are used during
1774 disconnection of primary router and in backup router protocol.
1775 Affected file silcd/server_util.[ch], silcd/server.c and
1776 silcd/server_backup.c.
1778 * Fixed channel adding to global list in IDENTIFY command
1779 reply in server. Affected file silcd/command_reply.c.
1781 Sat Nov 10 21:39:22 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1783 * If the incoming packet type is REKEY or REKEY_DONE process
1784 that packet always synchronously. Fixes yet another MAC
1785 failed error on slow (dialup) connections. Affected file
1786 lib/silcclient/client.c and silcd/server.c.
1788 Thu Nov 8 22:21:09 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1790 * Call check_version SKE callback for initiator too. Affected
1791 file lib/silcske/silcske.c.
1793 * Implemented fix for security hole found in the SKE that was
1794 fixed in the specification few days back; the initiator's
1795 public key is now added to the HASH value computation.
1796 Added backwards support for the old way of doing it too, for
1797 old clients and old servers. Affected file is
1798 lib/silcske/silcske.c.
1800 * Enabled mutual authentication by default in SKE. If initiator
1801 is not providing mutual authentication the responder will
1802 force it. This will provide the proof of posession of the
1803 private key for responder. The affected files are
1804 lib/silcclient/protocol.c and silcd/protocol.c.
1806 * Do not cache anymore the server's public key during SKE.
1807 We do mutual authentication so the proof of posession of
1808 private key is done, and if the server is authenticated in
1809 conn auth protocol with public key we must have the public
1810 key already. Affected file silcd/protocol.c.
1812 * Added new global debug variable: silc_debug_hexdump. If
1813 it is set to TRUE SILC_LOG_HEXDUMP will be printed. Affected
1814 file lib/silcutil/silclog.[ch].
1816 * Fixed compilation warning due to char * -> const char *.
1817 Affected files lib/silcutil/silcnet.h, and
1818 lib/silccore/silcauth.[ch].
1820 Wed Nov 7 20:43:03 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1822 * Fixed CMODE command when new channel key was created. If
1823 the creation failed the old key was removed. Next time giving
1824 same command would crash the server since the old key was
1825 freed already. Affected file silcd/command.c.
1827 * Fixed the silc_server_announce_get_channels to not crash
1828 on reconnect. Affected file silcd/server.c.
1830 Wed Nov 7 17:15:07 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1832 * Added silc_log_set_debug_string function to set a regex
1833 string to match for debug output. Only the function names,
1834 or filenames matching the given debug string is actually
1835 printed. This way it is possible to filter out those debug
1836 strings that user is not interested in.
1838 Fixed a bug in silc_string_regexify.
1840 Affected files lib/silcutil/silclog.[ch], and
1841 lib/silcutil/unix/silcunixutil.c.
1843 * Changed the -d options in both server and Irssi SILC client
1844 to take the debug string as argument. Affected files
1845 silcd/silcd.c and irssi/src/silc/core/silc-core.c.
1847 Tue Nov 6 21:31:54 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1849 * Added silc_hash_babbleprint to create a Bubble Babble
1850 Encoded fingerprint. The encoding is developed by Antti
1851 Huima (draft-huima-babble-01.txt), and it creates human
1852 readable strings out of binary data. Affected file
1853 lib/silccrypt/silchash.[ch].
1855 * Print the babble print now in addition of fingerprint as well
1856 in Irssi SILC client. Affected files are
1857 irssi/src/fe-common/silc/module-formats.[ch],
1858 irssi/src/fe-common/silc/core/client_ops.c.
1860 Sun Nov 4 23:37:28 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1862 * Fixed a security problem found in SKE. The initiator's
1863 public key too is now added to the HASH hash value creation
1864 which is signed by the responder to create the SIGN value.
1865 This will prevent anyone in the middle to lie to the responder
1866 about the initiator's public key. If this is done now, the
1867 man in the middle will get caught. Updated the protocol
1870 Sun Nov 4 11:43:53 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1872 * Better installation directory handling. Configure module
1873 paths and other paths automatically to example_silc* files
1874 in doc/. A patch by toma.
1876 * Fixed compiler warning from MPI library, and from SILC RNG.
1879 * Added SILC_SERVER_PID_FILE to define the pid file for server.
1880 It can be configured with ./configure. A patch by toma.
1882 Sat Nov 3 23:48:23 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1884 * Find correct make to use in prepare-clean. A patch by
1885 toma. Affected file prepare-clean.
1887 Sat Nov 3 22:04:00 PST 2001 Brian Costello <bc@mksecure.com>
1889 * Added irssi variables use_auto_addr, auto_bind_ip,
1890 auto_bind_port and auto_public_ip.
1892 * Changed the interface for silc_client_send_key_agreement
1893 in lib/silcclient/silcapi.h
1897 irssi/src/silc/core/silc-core.c
1899 lib/silcclient/silcapi.h
1900 irssi/src/silc/core/silc-channels.c
1901 lib/silcclient/client_keyagr.c
1904 Sat Nov 3 17:48:55 EET 2001 Pekka Riikonen <priikone@silcnet.org>
1906 * Added silc_pkcs_public_key_compare to compare two
1907 public keys. Affected file lib/silccrypt/silcpkcs.[ch].
1909 * Check that the client who set the founder mode on the
1910 channel is the same client that is giving the founder
1911 mode to itself. It is done by comparing the saved public
1912 key (it is saved even in the authentication is passphrase).
1913 Affected file silcd/command.c.
1915 Fri Nov 2 18:52:08 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1917 * Do not process packet for disconnected socket connection.
1918 Affected file lib/silccore/silcpacket.c.
1920 * Process the DISCONNECT packet through scheduler in the
1921 client library. Affected file lib/silcclient/client.c.
1923 * Fixed the silc_client_packet_parse to not to increase
1924 the packet sequence number if the conn->sock and the
1925 current socket connection is not same. This can happen
1926 for example during key agreement when the conn includes
1927 multiple socket connections (listeners). Affected file
1928 lib/silcclient/client.c.
1930 * The sender of the file transfer request now provides also
1931 the pointer (listener) for the key exchange protocol. If
1932 the listener cannot be created then it sends empty key
1933 agreement and lets the receiver provide the listener.
1935 Added `local_ip' and `local_port' arguments to the
1936 silc_client_file_send. If they are provided they are used,
1937 if not then it will attempt to find local IP address, if
1938 not found or bind fails then the remote client will provide
1941 Affected files are lib/silcclient/client_ftp.c and
1942 lib/silcclient/silcapi.h.
1944 * Extended the FILE SEND command to support defining the
1945 local IP and port for key exchange listener. They are
1946 optional. Affected file irssi/src/silc/core/silc-servers.c.
1948 Thu Nov 1 22:10:07 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1950 * Defined to WHOIS command reply the sending of fingerprint
1951 of the client's public key (if the proof of posession of the
1952 corresponding private key is verified by the server).
1953 Updated to the protocol specification.
1955 * Added support of receiving the client's public key's
1956 fingerprint in command reply in client library. Affected
1957 file is lib/silcclient/command_reply.c, and
1958 lib/silcclient/idlist.[ch].
1960 Thu Nov 1 18:06:12 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1962 * Do not send over 128 chars long nickname to the server
1963 in NICK command. Affected file lib/silcclient/command.c.
1965 * Do not send over 256 chars long channel names to the server
1966 in JOIN command. Affected file lib/silcclient/command.c.
1968 Tue Oct 30 22:48:59 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1970 * Assure that silc_server_close_connection cannot be called
1971 twice for same socket context. Affected file is
1974 Tue Oct 30 16:58:14 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1976 * Send error message to application if opening file for
1977 writing during file transfer fails. Affected file is
1978 lib/silcclient/client_ftp.c.
1980 Remove all file transfer sessions for a client that we're
1981 removing from ID cache.
1983 Affected file is lib/silcclient/client_ftp.c.
1985 * Fixed silc_net_addr2bin to return correct address. Affected
1986 file lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
1988 * Fixed file transfer session removing on signoff notify.
1989 Affected file irssi/src/silc/core/silc-servers.c.
1991 * Added the SilcClientFileError to be returned in the monitor
1992 callback. Added NO_SUCH_FILE and PERMISSION_DENIED errors.
1993 Affected file lib/silcclient/silcapi.h.
1995 Mon Oct 29 17:43:04 EST 2001 Pekka Riikonen <priikone@silcnet.org>
1997 * Fixed a crash in silc_client_ftp_free_sessions and
1998 silc_client_ftp_session_free_client. Affected file
1999 lib/silcclient/client_ftp.c.
2001 * Added `disabled' field in the SilcChannelEntry in the server
2002 to indicate if the server entry is disabled. Affected file
2003 silcd/idlist.h, silcd/command[_reply].c.
2005 * SILC server adds now /var/run/silcd.pid everytime it is
2006 started. Affected file silcd/silcd.c.
2008 * Added silc_server_packet_send_clients to send a packet to
2009 the provided table of client entries. Affected file
2010 silcd/packet_send.[ch].
2012 * Fixed a crash in client resolving in client_prvmsg.c in
2013 client library. Affected file lib/silcclient/client_prvmsg.c.
2015 * Do not actually remove the client directly from ID cache
2016 during SERVER_SIGNOFF, but invalidate it. This way we
2017 preserve the WHOWAS info for the client. Affected file
2018 silcd/server_util.c.
2020 * Fixed SERVER_SIGNOFF notify handling in the server. The
2021 server is now able to process incoming SERVER_SIGNOFF notify
2022 for a server that it doesn't even know about. It will remove
2023 the clients provided in the notify. Affected file
2024 silcd/packet_receive.c.
2026 * Check for partial packet in data queue after every packet that
2027 was found from the queue. Return and wait for more data if
2028 there is partial data in queue. Affected file is
2029 lib/silccore/silcpacket.c.
2031 Sun Oct 28 18:46:27 EST 2001 Pekka Riikonen <priikone@silcnet.org>
2033 * Added SilcClietFileError enum to indicate error in
2034 file transfer. Added SILC_CLIENT_FILE_MONITOR_KEY_AGREEMENT
2035 and SILC_CLIENT_FILE_MONITOR_ERROR new monitor statuses.
2036 Affected files lib/silcclient/silcapi.h and
2037 lib/silcclient/client_ftp.c.
2039 * Check that newsize in silc_buffer_realloc is larger than
2040 the old buffer's size. Affected file lib/silcutil/silcbufutil.h.
2042 * Added better monitor of file transfers. It now monitors
2043 key agreement protocol during the file transfer too. Added
2044 error reporting too. Affected files
2045 irssi/src/silc/core/silc-servers.c,
2046 irssi/src/fe-common/silc/module-formats.[ch].
2048 * Wrote a help file for FILE command.
2050 * Added silc_rng_global_get_byte_fast to get not-so-secure
2051 random data as fast as possible. Random data is read from
2052 /dev/urandom if available and from the SILC RNG if not
2053 available. It is used in padding generation. Affected file
2054 lib/silccrypt/silcrng.[ch].
2056 * All packets in client library are now processed synchronously.
2057 Optimized packet processing a lot. Affected file
2058 lib/silcclient/client.c.
2060 * All server connection packets are processing synchronously
2061 now in server, to optimize packet processing. Affected file
2064 * Include files are installed now only in Toolkit distribution
2065 if make install is given. Affected files: all Makefile.am's.
2067 Thu Oct 25 22:44:06 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2069 * Assure that silc_client_notify_by_server_resolve does not
2070 resolve the client information multiple times. If it cannot
2071 be found by the first it cannot be found at all. Affected
2072 file lib/silcclient/client_notify.c.
2074 * Fixed WHOWAS command reply calling. Affected file
2075 lib/silcclient/command_reply.c.
2077 * Removed all references to silc_idlist_get_client from the
2078 Irssi SILC client since that call is internal call used by
2079 the library. The Irssi SILC client will use now client
2080 retrieval functions found in silcapi.h.
2082 * Fixed a bug in resolving nickname info before sending
2083 private message. It used freed memory. Affected file
2084 irssi/src/silc/core/silc-servers.c.
2086 Thu Oct 25 19:04:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2088 * Assure my_channels statistics cannot go negative in server.
2089 Affected files silcd/server.c, silcd/server_util.c.
2091 Wed Oct 24 19:53:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>

2101 lib/sftp/sftp_fs_memory.c.
2103 Mon Oct 22 16:35:05 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2105 * Added silc_net_localip to return local host's IP address.
2106 Affected file lib/silcutil/silcnet.[ch].
2108 * If key exchange or rekey protocol is active for a connection
2109 parse all packets syncronously since there might be packets
2110 in packet queue that we are not able to process without first
2111 processing packets before them. Affected file silcd/server,
2112 lib/silcclient/client.c.
2114 * SilcPacketParserCallback now returns TRUE or FALSE to indicate
2115 whether library should continue processing the packet.
2116 Affected file lib/silccore/silcpacket.h.
2118 * Added SilcSFTPMonitor callback, SilcSFTPMonitors and
2119 SilcSFTPMonitorData to SFTP server to monitor various

2139 * Relay the SILC_PACKET_FTP in the server. Affected files
2140 silcd/server.c and silcd/packet_receive.c.
2142 Sun Oct 21 20:21:02 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2144 * Renamed silc_file_read and silc_file_write to functions
2145 silc_file_readfile and silc_file_writefile. Added function
2146 silc_file_open and silc_file_close. Affected files
2147 lib/silcutil/silcutil.[ch].
2149 Thu Oct 18 20:58:13 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2151 * Resolve the client info when received private message or
2152 channel message for a client which nickname we don't know.
2153 Affected files lib/silcclient/client_prvmsg.c and
2154 lib/silcclient/client_channel.c.
2156 * Do not crash in /KEY if client is not connected. Affected
2157 file irssi/src/silc/core/silc-channels.c.
2159 * Added SilcClientStatus field to the SilcClientEntry in the
2160 lib/silcclient/idlist.h.
2162 Added SILC_CLIENT_STATUS_RESOLVING to mark that the entry
2163 is incomplete and is being resolved, it won't be resolved
2166 Make sure also that USERS command reply does not resolve
2167 twice information. Affected file is
2168 lib/silcclient/command_reply.c.
2170 Make sure that silc_client_get_clients_by_list does not
2171 resolve twice same information.
2173 * Check for valid client->id in the silc_server_free_client_data.
2174 Affected file silcd/server.c.
2176 * Fixed /GETKEY nick@server not to crash if the server entry
2177 is not found. Affected file lib/silcclient/command.c.
2179 * Fixed the silc_server_check_cmode_rights to check the
2180 requested modes correctly. Affected file silcd/command.c.
2182 Thu Oct 18 12:10:22 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2184 * Better checks for non-printable chars in nick added.
2185 Affected file silcd/command.c.
2187 Thu Oct 18 09:18:58 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2189 * Call the silc_server_udpate_servers_by_server in the
2190 primary router that comes back online in the backup resuming
2191 protocol. Otherwise it routes packets wrong. Affected file
2192 silcd/server_util.[ch], silcd/server_backup.c.
2194 Wed Oct 17 16:51:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2196 * Added SILC_STR_UI8_[N]STRING[_ALLOC] formats to the
2197 lib/silcutil/silcbuffmt.[ch].
2199 * Redefined the SILC packet header to include the padding
2200 length. Affected file lib/silccore/silcpacket.[ch].
2202 * Added SILC_PACKET_PADLEN_MAX macro to return the padding
2203 length for maximum padding up to 128 bytes). Affected
2204 file lib/silccore/silcpacket.h.
2206 * Removed all backwards support for old 0.5.x MAC thingies.
2207 The SILC packet header change makes it impossible to be
2208 backwards compatible.
2210 * Send the ENDING packet with timeout in the backup resuming
2211 protocol. This is to assure that all routers has connected
2212 to the primary router. Affected file silcd/server_backup.c.
2214 * Changed the RNG to take the first IV from random data. It
2215 used to take it from zero actually. Changed the RNG also
2216 to use /dev/urandom during session. /dev/random is used
2217 in initialization. Affected file lib/silccrypt/silcrng.[ch].
2219 Tue Oct 16 20:45:49 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2221 * Changed the SILC packet header to have the first two bytes
2222 (the packet length) encrypted. Affected files aroung the
2223 code tree, lib/silccore/silcpacket.[ch]. Removed the
2224 SilcPacketCheckDecrypt callback. It is not needed anymore
2225 since the silc_packet_receive_process will determine now
2226 whether the packet is normal or special.
2228 * Implemented the unidirectional MAC keys. Affected files
2229 lib/silcske/silcske.c, silcd/protocol.c and
2230 lib/silcclient/protocol.c.
2232 * Implemented the packet sequence number to the MAC computation.
2233 Affected files lib/silccore/silcpacket.c, silcd/protocol.c,
2234 silcd/packet_send.c, silcd/server.c, lib/silcclient/client.c,
2235 lib/silcclient/protocol.c.
2237 Mon Oct 15 17:42:55 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2239 * Allow backup router to announce servers. All servers
2240 announced by backup router are added to the global list
2241 automatically. Update hte server's socket to our primary
2242 router also when backup router announces a server.
2243 Affected file silcd/packet_receive.c.
2245 * Do not update the client->router in the function
2246 silc_server_udpate_clients_by_server if the client is on
2247 global list. We might fail to find any specific server
2248 for locally connected clients and local cell clients. They
2249 should still use the `from' and not `to' as client->router.
2250 This fixes backup router resuming protocol. Affected file
2251 silcd/server_util.c.
2253 * Decrease channel statistics count only if the channel
2254 deletion worked. Affected files are silcd/server.c and
2255 silcd/server_util.c.
2257 * Added silc_server_update_servers_by_server to update origin
2258 of all server entries. Used during backup router protocol.
2259 Affected files silcd/server_util.[ch], silcd/server.c. and
2260 silcd/backup_router.c.
2262 * ROBODoc documented the lib/silccrypt/silchmac.h. Added new
2263 function silc_hmac_init, silc_hmac_update, silc_hmac_final,
2264 silc_hmac_get_hash and silc_hmac_get_name. Affected file
2265 lib/silccrypt/silchmac.c.
2267 Sun Oct 14 18:28:22 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2269 * Assure that router cannot reroute the same channel message
2270 to the sender. Affected file silcd/packet_receive.c.
2272 Sat Oct 13 12:46:18 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2274 * Made better checks that the channel message is not sent
2275 to the router it came from. Affected file is
2276 silcd/packet_send.c. Fixed memory leak too.
2278 * Announce informations for incoming router connection, but
2279 only after checking if it is replaced by backup router.
2280 Affected file silcd/packet_receive.c.
2282 Fri Oct 12 18:37:24 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2284 * Fixed the backup resuming protocol to work in multiple
2285 router environment. Affected file silcd/server_backup.c.
2287 * Route packet only to one router in the function
2288 silc_server_packet_send_to_channel. Affected file is
2289 silcd/packet_send.c.
2291 * Fixed silc_server_send_notify_dest to set the broadcast
2292 flag. Fixed the silc_server_send_notify_topic to actually
2293 send the TOPIC_CHANGE notify and not SERVER_SIGNOFF notify.
2294 Affected file silcd/packet_send.c.
2296 * Changed the SFTP Filesystem interface. Changed the
2297 SilcSFTPFilesystemStruct to SilcSFTPFilesystemOps to include
2298 the filesystem operation function. The SilcSFTPFilesystem
2299 is now a context that is allocated by all filesystem allocation
2300 functions and it already includes the operations structure
2301 and filesystem specific context. It is given as argument
2302 now to the silc_sftp_server_start. This made the interface
2303 a bit cleaner. Affected file lib/silcsftp/silcsftp[_fs].h,
2304 lib/silcsftp/sftp_fs_memory.c and sftp_server.c.
2306 Thu Oct 11 22:19:26 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2308 * Changed the backup router adding and getting interfaces
2309 in the server. The router that will be replaced by the
2310 specified backup router is now sent as argument. Affected
2311 files silcd/serverconfig.[ch], silcd/backup_router.[ch], and
2314 * Added silc_net_addr2bin_ne to return the binary form of
2315 the IP address in network byte order. Affected files
2316 lib/silcutil/[unix/win32].silc[unix/win32]net.[ch].
2318 Thu Oct 11 12:14:19 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2320 * Check for existing server ID in silc_server_new_server
2321 and in silc_server_connect_to_router_final and remove the
2322 old entry if it exists. Affected file silcd/packet_receive.c,
2325 * Send the channel message always to only one router, either
2326 in upstream or downstream. Affected file is
2327 silcd/packet_send.c.
2329 Tue Oct 9 17:45:43 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2331 * Wrote the definition of the backup resuming protocol to the
2332 protocol specification.
2334 * Removed one redundant channel key generation from normal
2335 server during joining procedure. Removed one redundant
2336 channel key sending from server to router during joining
2337 procedure. Affected file silcd/command.c.
2339 * Made minor bugfixes to the backup router resuming protocol.
2340 Affected file silcd/server_backup.c, server.c.
2342 Mon Oct 8 16:47:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2344 * Added --disable-asm configuration option. Affected files
2345 configure.in.pre, lib/silcmath/mpi/configure.in. A patch
2348 * Implemented the backup resuming protocol that is used to
2349 resume the primary router position in the cell after the
2350 primary router comes back online. Affected files
2351 silcd/server_backup.[ch], silcd/server, silcd/packet_receive.c,
2352 and silcd/server_util.[ch].
2354 Sun Oct 7 12:29:25 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2356 * Sleep two (2) seconds after sending QUIT command to server.
2357 Affected file lib/silcclient/command.c.
2359 * Assure that if outgoing data buffer is pending do not force
2360 send any data. Affected file silcd/packet_send.c.
2362 * Assure that if outgoing data buffer is pending do not force
2363 send any data. Affected file lib/silcclient/client.c.
2365 * Implemented the backup router support when the primary router
2366 goes down. The servers and routers can now use the backup
2367 router as new primary router without loosing connectivity.
2369 Sat Oct 6 21:18:54 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2371 * Added new SILC_IDLIST_STATUS_DISABLED flag for entries
2372 in the server to indicate disabled entry. All data read
2373 from the connection will be ignored and no data is sent
2374 for entry that is disabled. Affected files are
2375 silcd/idlist.h, silcd/server.c.
2377 Fri Oct 5 00:03:29 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2379 * Created SFTP client and server test programs in the
2380 lib/silcsftp/tests directory.
2382 Wed Oct 3 23:31:42 EDT 2001 Pekka Riikonen <priikone@silcnet.org>
2384 * Implemented memory filesystem (virtual filesystem) for
2385 SFTP server. Affected file lib/silcsftp/silcsftp_fs.h,
2388 Sun Sep 30 22:10:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2390 * Implemented the SFTP (SSH File Transfer Protocol) to the
2391 lib/silcsftp. It includes SFTP client and SFTP server
2394 Sun Sep 30 10:35:44 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2396 * Moved lib/silccore/silcprotocol.[ch] to the
2397 lib/silcutil library.
2399 * Added silc_buffer_format_vp and silc_buffer_unformat_vp to
2400 take variable argument list pointer as argument. Affected
2401 file lib/silcutil/silcbuffmt.[ch].
2403 * Added silc_buffer_set function that is used to set data
2404 to a SilcBuffer that is not allocated at all (SilcBufferStruct).
2405 Affected file lib/silcutil/silcbuffer.h.
2407 * Changed various routines in the core library to use the new
2408 silc_buffer_set instead of allocating new buffer only for
2411 * Added 64-bit value formatting and unformatting support to the
2412 silc_buffer_[un]format routines. Affected file is
2413 lib/silcutil/silcbuffmt.[ch].
2415 Added also 64-bit macros: SILC_GET64_MSB and SILC_PUT64_MSB,
2416 to includes/bitmove.h.
2418 Fri Sep 28 21:30:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2420 * Fixed channel user mode saving in client library. Affected
2421 file lib/silcclient/command[_reply].c.
2423 Thu Sep 27 22:52:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2425 * Defined the file transfer to the SILC Protocol. Added
2426 new packet type SILC_PACKET_FTP and defined File Transfer
2427 Payload. The mandatory file transfer protocol is SFTP
2428 (SSH File Transfer Protocol). Affected file in addition
2429 of the internet draft is lib/silccore/silcpacket.h.
2431 * Deprecated the SILC_PACKET_CELL_ROUTERS and defined new
2432 packet SILC_PACKET_RESUME_ROUTER instead. The new packet
2433 is used as part of backup router protocol when the primary
2434 router of the cell is back online and wishes to resume
2435 the position as primary router.
2437 * Redefined the MAC generation keys in the protocol. The
2438 same key is not used anymore in both direction. Both
2439 direction will now use different keys for sending and
2440 receiving. This fixes a potential security flaw. This
2441 change causes incompatibilities in the protocol.
2443 * Redefined also the MAC computation from the packet.
2444 An packet sequence number is now added to the MAC
2445 computation. This prevents possible replay attacks against
2446 the protocol. This change too causes incompatibilities
2449 Added `sequence' field to the SilcPacketContext to hold
2450 the current sequence number for the packet.
2452 Wed Sep 26 20:15:22 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2454 * Added `created' field to the SilcIDListData in the file
2455 silcd/idlist.h to indicate the time when the entry was
2458 * Added `created' field to the SilcChannelEntry too. Affected
2459 file silcd/idlist.h.
2461 * Added `creation_time' aguments to all the announcement functions
2462 in the server. If it is provided then only the entries that
2463 was created after the provided time frame are actually
2464 announced. Affected file silcd/server.[ch].
2466 * The protocol says that the Channel ID's IP address must be
2467 based on the router's IP address. Added check for this in
2468 the silc_server_new_channel when processing incoming New Channel
2469 Payload. Affected file silcd/packet_receive.c.
2471 * Print out the correct version with --version in SILC client.
2472 Affected file irssi/src/silc/core/silc-core.c.
2474 Mon Sep 24 17:19:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2476 * Fixed WHOWAS command to check for completnes of the client
2477 entry always, not just when the command is coming from client.
2478 Affected file silcd/command.c.
2480 * Added new function silc_server_packet_queue_purge to purge the
2481 outgoing data queue to the network. After the function returns
2482 it is guaranteed that the outgoing packet queue is empty.
2483 Affected file silcd/packet_send.[ch].
2485 * Purge the outgoing packet queue in the rekey protocol's final
2486 callback to assure that all rekey packets go to the network
2487 before quitting the protocol. Affected file silcd/server.c.
2489 * Added silc_client_packet_queue_parse as similar function as
2490 in server to the client library. The affected file is
2491 lib/silcclient/client.c.
2493 Sun Sep 23 15:15:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2495 * Splitted silcd/server.c and created silcd/server_util.[ch]
2496 for utility functions.
2498 * Added new socket flag SILC_SF_DISABLED to indicate that the
2499 connection is open but nothing can be sent to or received from
2500 the connection. Affected file lib/silcutil/silsockconn.[ch].
2501 The checking for disabled socket is checked in the low level
2502 silc_socket_write and silc_socket_read functions.
2504 Thu Sep 20 23:11:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2506 * Allow only nicknames and channel names that fits into the
2507 7-bit unsigned char ASCII set. Affected file silcd/command.c.
2509 Thu Sep 20 18:04:12 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2511 * When processing JOIN command reply in server check that if
2512 the channel exists in our global list we'll move it the local
2513 list. Affected file silcd/command_reply.c.
2515 * Fixed the check whether client is joined on the channel already
2516 in JOIN command. Affected file lib/silcclient/command.c.
2518 * Fixed the JOIN command reply to check whether the channel
2519 already exists. Affected file lib/silcclient/command_reply.c.
2521 Wed Sep 19 22:58:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2523 * Added silc_ske_status_string to map the SKE error numbers
2524 to readable strings. The affected files are
2525 lib/silcske/silcske[_status].[ch].
2527 Tue Sep 18 22:50:41 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2529 * Do not show the private channels on the WHOIS channel list
2530 as it is not allowed by the protocol. The affected file is
2533 Sun Sep 16 12:32:58 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2535 * Assure that the packet length digged from the actual packet
2536 is something sensible in the silc_packet_decrypt_rest_special
2537 in lib/silccrypt/silcpacket.c.
2539 * Free and NULL the allocated pointer in silc_hmac_alloc if
2540 the HMAC allocation fails. The affected file is
2541 lib/silccrypt/silchmac.c.
2543 * Print the selected security properties to the log files in
2544 the server. Affected file silcd/protocol.c.
2546 * Add SKE's reference counter even if calling the completion
2547 callback manually. Otherwise it goes negative, although it
2548 does not cause any problems. The affected file is
2549 lib/silcske/silcske.c.
2551 * Remove the client entry with short timeout after giving the
2552 KILL command. Affected file lib/silcclient/command.c.
2554 * Fixed to send error reply in WHOIS and IDENTIFY commands in
2555 case all found clients are already disconnected (WHOWAS would
2556 found them) in the server. Affected file silcd/command.c.
2558 * Update the last_receive (time of last data received) to be
2559 updated only when received private or channel message so that
2560 the idle time showed in WHOIS makes more sense.
2562 * Added boolean field `valid' in to the SilcClientEntry in the
2563 client library to indicate whether the entry is valid or not.
2564 This fixes the nickname change bug on channel when changing
2565 the nickname to be same than the old (like nick to Nick) the
2566 nickname formatter doesn't set the new nick anymore to Nick@host.
2567 Affected file lib/silcclient/idlist.[ch].
2569 * Now actually fixed the nickname changing on disconnection.
2570 Added new function silc_change_nick to the Irssi SILC Client.
2571 Affected file irssi/src/silc/core/client_ops.c,
2572 irssi/src/silc/core/silc-nicklist.[ch].
2574 Sat Sep 15 13:29:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2576 * Check that the public key exists in the GETKEY command before
2577 trying to encode it. Affected file silcd/command.c.
2579 * Print some notifications on received public keys with GETKEY
2580 command in the Irssi SILC Client. Affected files are
2581 irssi/src/fe-common/silc/module-formats.[ch],
2582 irssi/src/silc/core/client_ops.c.
2584 * Use IDENTIFY command to resolve the server information in the
2585 GETKEY command instead of INFO command. Affected file
2586 lib/silcclient/command.c.
2588 * All command reply functions in the client library now calls
2589 the pending command reply callbacks even if an error has
2590 occurred. The server has done this a long time and now it was
2591 time to move the client library to this as well. Now all
2592 errors can be delivered back to the pending command reply
2593 callbacks if necessary. Affected files are
2594 lib/silcclient/command[_reply].[ch].
2596 * Change the nickname on disconnection back to the username
2597 because in reconnect the server will enforce it to it anyway.
2598 Affected file irssi/src/silc/core/silc-servers.c.
2600 * Fixed a config file parsing bug in the Irssi SILC client.
2601 Affected file irssi/src/silc/core/clientconfig.c.
2603 Thu Sep 13 23:11:18 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2605 * When printing the channel mode on JOIN, verify that the
2606 channel key and channel's HMAC are valid. Affected file
2607 irssi/src/silc/core/client_ops.c.
2609 Thu Sep 13 20:24:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2611 * Added defines SILC_DEFAULT_CIPHER, SILC_DEFAULT_HMAC,
2612 SILC_DEFAULT_HASH and SILC_DEFAULT_PKCS in the file
2613 lib/silccrypt/[silccipher.h|silchmac.h|silchash.h|silcpkcs.h].
2615 * Removed channel key rekey task deleting from the function
2616 silc_server_save_channel_key. Affected file silcd/server.c.
2617 Added explicit timeout task context instead that is used to
2618 delete the task if we are registering a new task before the
2619 new task has elapsed.
2621 * When channel key rekey occurs the client library now saves
2622 the old channel key for a short period of time (10 seconds) and
2623 is able to use it in case some is still sending channel
2624 messages encrypted with the old key after the rekey. Affected
2625 file lib/silcclient/[idlist.h|client_channel.c].
2627 Sun Sep 9 15:49:16 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2629 * Added check to the silc_server_new_id_real to not accept
2630 new ID if it is the sender's own ID. Affected file is
2631 silcd/packet_receive.c.
2633 * Assure that we do not announce ourself or the one we've
2634 sending our announcements when we're router and are announcing
2635 servers to our primary router. Affected file silcd/server.c.
2637 * Fixed silc_server_command_identify_check_client to assemble
2638 correct WHOIS packet. It send corrupted WHOIS packet and
2639 caused problem with router to router connections. Affected
2640 file silcd/command.c.
2642 Fixed also silc_server_command_whois_check the same way
2643 as for the IDENTIFY command.
2645 * Added new SilcIDListStatus to the server in the SilcIDListData
2646 structure. The status now includes the current status of
2647 the entry (like registered, resolved etc.). Affected file
2648 silcd/idlist.[ch]. Defined a bunch of different status types
2649 as well. This replaced the old boolean registered field as well.
2651 Added resolve_cmd_ident field to the SilcClientEntry structure
2652 too so that if the entry is for example being resolved so
2653 another command may attach to the same pending command reply
2654 without requiring to resolve the same entry again. This concept
2655 should optimize the WHOIS and the IDENTIFY resolving under
2656 heavy load by taking away unnecessary resolving for entries
2657 that are being resolved already.
2659 Added support for adding multiple pending commands for one
2660 command idenfier. Affected file silcd/command[_reply].[ch].
2662 * Fixed WHOIS and IDENTIFY save to remove the cache entry
2663 before deleting the data. Otherwise the hash table will have
2664 freed data in comparison functions. Affected file is
2665 silcd/command_reply.c.
2667 * Fixed silc_idlist_replace_client_id to add the new entry to
2668 the cache with NULL nickname. Otherwise there will be invalid
2669 memory as the nickname after the nickname is freed. Affected
2670 file silcd/packet_receive.c.
2672 * Fixed the silc_idlist_get_clients_by_hash. The entries was
2673 saved into wrong slots because the previous number of entries
2674 was not taken into account. Affected file silcd/idlist.c.
2675 Fixed same thing in silc_idlist_get_clients_by_nickname too.
2677 * If we are router and we receive JOIN notify to a channel that
2678 does not have any users then notified client is marked as the
2679 channel founder, as it is it. The affected file is
2680 silcd/packet_receive.c
2682 * Added to the extended hash table API's table_del_*ext functions
2683 the destructor as argument too, so that the caller can decide
2684 which destructor to use or whether to use destructor at all.
2685 Affected file lib/silcutil/silchashtable.[ch].
2687 * Fixed ID Cache purging. It actually deleted the entries from
2688 the hash table after the data was freed. The hash table ended
2689 up comparing freed memory. The affected file is
2690 lib/silccore/silcidcache.c.
2692 Sat Sep 8 10:22:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2694 * Fixed Irssi SILC client's KILL command's HELP syntax.
2696 * The USERS command now resolves the detailed user information
2697 if the userinfo field is missing. Affected file is
2698 lib/silcclient/command_reply.c.
2700 * Do not print error in silc_file_read if the read file does
2701 not exist. Just silently return NULL. Affected file is
2702 lib/silcutil/silcutil.c.
2704 * Fixed the silc_log_output to not wine about NULL filename
2705 and to not create some bogus " " filename. Affected file is
2706 lib/silcutil/silclog.c.
2708 Fri Sep 7 22:16:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2710 * Fixed various printing bugs on the user interface in the
2711 Irssi SILC Client. Minor changes that were forgotten from
2714 Fri Sep 7 17:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2716 * Fixed the configure.in.pre and the compilation and distribution
2717 environment to support the new autoconf 2.52. That version is
2718 now required to compile the CVS trunk.
2720 Thu Sep 6 12:47:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2722 * Renamed function silc_parse_nickname to silc_parse_userfqdn
2723 to generally parse user@fqdn format strings. Affected file
2724 lib/silcutil/silcutil.c.
2726 * Added nickname_format and nickname_force_format fields to the
2727 SilcClientParams structure. The first one defines the format
2728 for the nicknames that the library will enforce if the receives
2729 multiple same nicknames. The second one is boolean value and
2730 can be used to force the library to always enforce the format
2731 to the nicknames regardles whether there are multiple nicknames
2732 or not. This configurable formatting was employed to flexibly
2733 support accessing multiple nicknames from the user interface.
2734 The userinterface can now set the nicknames to what ever format
2735 they prefer. Affected file lib/silcclient/silcapi.h.
2737 Added function silc_client_nickname_format to the file
2738 lib/silcclient/idlist.c. It performs the nickname formatting.
2740 Added new field `hostname´ to the SilcClientEntry context.
2741 It holds the hostname of the client. Affected file is
2742 lib/silcclient/idlist.h.
2744 * Irssi SILC Client sets the nicknames in nick@hostn format.
2745 Fe. priikone@otaku, priikone@otaku2 etc. Affected file
2746 irssi/src/silc/core/silc-core.c.
2748 The WHOIS printing now also shows both the real nickname and
2749 the formatted nickname so that user knows how to access the
2750 user if there are multiple same nicknames cached. Affected
2751 file irssi/src/silc/core/client_ops.c. Changed the WHOIS
2752 printing formatting too to take the hostname now as a separate
2753 argument. The Affected file is
2754 irssi/src/fe-common/silc/modules-formats.[ch].
2756 * Changed the silc_client_get_clients_local to accept the formatted
2757 nickname as argument. It accepts the real nickname too but the
2758 formatted nickname can be used to find the true entry from
2759 multiple entries. Affected file lib/silcclient/silcapi.h and
2760 lib/silcclient/idlist.c.
2762 * Added nickname_format_parse field to the SilcClientParams.
2763 It is a callback function provided by the application to parse
2764 the nickname out of the formatted nickname string. The library
2765 calls it to get the nickname from the formatted string. Since
2766 the application generally knows better the format of the nickname
2767 string it parses it instead of the library, even though library
2768 encodes the formatted string. If the callback function is not
2769 provided then the library will use the string as is. The
2770 affected file is lib/silcclient/silcapi.h.
2772 * All the nickname strings passed to the client library in
2773 commands are now expected to be formatted nickname strings.
2774 If the command does not support the formatted nickname string
2775 it will assume that the sent string is the actual nickname.
2776 Affected file lib/silcclient/command.c.
2778 Tue Sep 4 22:31:28 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2780 * Added public key authentication support to OPER and SILCOPER
2781 commands in the client library. Affected file is
2782 lib/silcclient/command.c.
2784 Tue Sep 4 12:39:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2786 * Changed the get_auth_methdod client operation to be asynchronous.
2787 It can be async if the application resolves the authentication
2788 method from the server during the negotiation. Added new
2789 SilcGetAuthMeth completion callback that the application will
2790 call after resolving the authentication method.
2792 Added function silc_client_request_authentication_method that
2793 the application can use to resolve the authentication method
2794 from the server. Added also SilcConnectionAuthRequest callback
2795 that the library will call after the server has replied. The
2796 application can call this function if it does not know the
2797 current authentication method.
2799 Affected files are lib/silcclient/client.c and
2800 lib/silcclient/silcapi.h.
2802 * The Irssi SILC client now automatically resolves the authentication
2803 method incase any configuration information is not present (and
2804 currently there never is). The affected file is
2805 irssi/src/silc/core/client_ops.c.
2807 * Fixed public key authentication from the client library.
2808 Affected file lib/silcclient/protocol.c. Changed also the
2809 protocol specification about the public key authentication in
2810 the connection authentication protocol. The actual data to be
2811 signed is now computed with a hash function before signing.
2813 * Fixed the public key authentication from the server as well.
2814 Affected file silcd/protocol.c.
2816 * Removed the mlock()'s from the memory allocation routines.
2817 Affected file lib/silcutil/silcmemory.c. The ./configure does
2818 not check anymore for the mlock(). Affected file is
2821 * Fixed USERS command in server to allow the execution of the
2822 command for private and secret channels if the client sending
2823 the command is on the channel. Affected file silcd/command.c.
2825 * Fixed silc_client_get_clients_local to return the clients
2826 count correctly. It could return wrong value. Affected file
2827 lib/silcclient/idlist.c.
2829 Mon Sep 3 20:09:59 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2831 * Fixed the lib/silcmath/mpi/mpi.h to always use 32-bit data
2832 types. The assembler optimizations seemed not to like 64-bit
2833 data types. The assmebler optimizations thus are now enabled
2834 also for BSD systems as opposed to only enable them for Linux.
2836 * Do not check for threads at all on BSD systems. Affected
2837 file configure.in.pre.
2839 * Removed -n and -h options from the Irssi SILC Client since
2840 they are not used in silc.
2842 * Fixed the prime generation to assure that the first digit
2843 of the generated random number is not zero since our conversion
2844 routines does not like number strings that starts with zero
2845 digit. If zero digit is seen the random number is regenerated.
2846 This caused some corrupted RSA keys when the zero first digit
2847 was met. Affected file lib/silcmath/silcprimegen.c.
2849 Sun Sep 2 17:17:24 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2851 * Fixed WIN32 configuration in the ./configure script.
2852 Fixed to include xti.h on environments that has it.
2853 Patches by Carsten Ilchmann and andrew.
2855 Sat Sep 1 00:29:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2857 * Changed the silc_id_create_client_id to be collision
2858 resistant. It is now assured that there cannot be created
2859 two same client ID's. I suspect that some weird bugs in
2860 the server were actually caused by duplicate Client IDs.
2861 Affected file silcd/serverid.[ch]. A router receiving
2862 new ID now also assures and informs the sending server
2863 if the ID caused collision.
2865 * Changed the silc_id_create_channel_id to also assure that
2866 there are no collisions.
2868 Wed Aug 29 17:55:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2870 * Statement about ignoring the Mutual Authentication flag when
2871 performing rekey with PFS was a bit misleading. It is ignored
2872 if it was set in the initial negotiation, it cannot be even
2873 set in the rekey. Fixed in the ke-auth draft. Started the
2874 new versions of the protocol drafts in the doc/.
2876 Sun Aug 26 14:59:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2878 * Fixed a bug in silc_client_command_identify_save when saving
2879 new channel information. The channel name was no duplicated
2880 and caused crash on exit. Affected file is
2881 lib/silcclient/command_reply.c.
2883 Fri Aug 17 23:07:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2885 * Fixed the getkey command handling in the server. Send just
2886 empty OK reply to the sender if the key could not be fetched
2887 (but everything else was ok, like the key just was not available).
2888 Changed the public key parameter to optional in the protocol
2889 specs so that empty OK reply can be sent. Affected file
2892 Added a message to Irssi SILC client to tell to user if the
2893 server did not return a public key.
2895 Tue Aug 14 07:29:27 CEST 2001 Pekka Riikonen <priikone@silcnet.org>
2897 * Fixed a channel key regeneration bug. It registered new
2898 timeout tasks exponentially until all system resources were
2899 used. Affected file silcd/server.c.
2901 Sun Aug 12 20:48:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2903 * Added the SILC Document generator to the scripts/silcdoc.
2904 It can be used to generate the Toolkit Reference Manual out
2905 of the source tree. Internally it will also use the RoboDoc
2906 generator now imported in util/robodoc.
2908 Sun Aug 12 12:28:17 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2910 * Added couple of return's in rekey protocol if error orccurred
2911 during the protocol. The execution must be terminated.
2912 Affected file silcd/protocol.c. Also, terminate the protocol
2913 always with timeout.
2915 Sat Aug 11 12:36:02 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2917 * The client's Client ID was created initally from the wrong
2918 nickname (it could have been in format nick@host) in the
2919 silc_server_new_client. Affected file silcd/packet_receive.c
2921 Sat Aug 11 00:29:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2923 * Added some SILC_LOG_ERROR's to various error conditions
2924 if client could not be added to ID cache. Affected files
2925 silcd/packet_receive.c and silcd/server.c.
2927 * When client's sock->user_data is freed, NULL also the
2928 client->router and client->connection pointers. Added check
2929 for these pointers being NULL to various places around the
2930 code. Affected file silcd/server.c.
2932 * Added client->data.registered == TRUE checks to various
2933 places around the code to assure that unregistered client's
2934 are not handled when it is not allowed. Affected file
2937 * Added `bool registered' fields to all
2938 silc_idlist_[server|client]_get_* routines to indicate whether
2939 the fetched client needs to be registered or not. Affected
2940 file silcd/idlist.[ch].
2942 * Add your own entry as registered to the ID cache in the
2943 server. Affected file server.c.
2945 * Fixed a bug in silc_server_new_server. The SilcServer was
2946 set as the new server's context instead of SilcServerEntry.
2947 This naturally caused some weird bugs.
2949 Thu Aug 9 18:28:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2951 * Do not delete the channel rekey task when adding it
2952 for in silc_server_create_channel_key.
2954 * Changed the silc_server_create_channel_key to return
2955 TRUE or FALSE to indicate the success of the channel key
2958 Thu Jul 26 11:32:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2960 * Fixed MSVC++ project files and added missing files to
2961 Makefiles under win32/.
2963 Wed Jul 25 18:43:54 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2965 * Do not add TCP_NODELAY flag if the operating system
2966 does not have it defined. Affected files are
2967 lib/silcutil/[unix/win32]/silc[unix/win32]net.c.
2969 * Fixed buffer overflow from Irssi SILC Client. Affected
2970 file irssi/src/fe-common/core/themes.c.
2972 * Fixed double free in client library in the file
2973 lib/silcclient/client.c when disconnecting from server.
2975 * Applied double free patch from cras to Irssi SILC client.
2976 Affected files irssi/src/core/[modules/expandos].c
2978 * Fixed the disconnection handling to Irssi SILC Client.
2979 The application must call silc_client_close_connection
2980 in ops->connect client operation in case of failure of
2981 the connection. Affected file is
2982 irssi/src/silc/core/client_ops.c.
2984 * Do not set sock->protocol to NULL in the function
2985 silc_client_close_connection after executing the protocol's
2986 final callback since the sock might not be valid anymore.
2987 Affected file lib/silcclient/client.c.
2989 Wed Jul 25 16:04:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
2991 * Do not enable SILC_THREADS if the linking with libpthread
2992 did not happen. Affected file configure.in.pre.
2994 * Added notion to protocol specification that server must
2995 verify the sent authentication payload with CMODE when
2996 setting the channel founder key. Implemented it to the
2997 server. Affected file silcd/command.c.
2999 Mon Jul 23 18:31:43 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3001 * Added _EXTRA_DIST SILC distribution variable to the
3002 distributions file. It is used to conditionally add extra
3003 files or directories to the specific distribution. Affected
3004 files ./prepare, Makefile.am.pre and distributions.
3006 Removed the `_' from the start of the distribution names.
3009 * Added README.WIN32 for instructions to compile the Toolkit
3012 Mon Jul 23 10:12:37 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3014 * Fixed a double free in disconnection in the server. Affected
3015 file is silcd/server.c.
3017 * Fixed the lib/silcske/groups.c to work now also with GMP
3018 MP library. The string conversion did not work when using
3019 specific base and the base is indicated in the string as well.
3021 * Created win32/ directory which now includes MSVC++ specific
3022 stuff so that toolkit (DLLs) may be compiled with MSVC++.
3023 It will appear only in the toolkit distribution
3025 Sun Jul 22 19:40:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3027 * Changed the key material distribution function in case when
3028 the hash output is too short. The data is now concatenated
3029 a bit differently than it used to. Made the change to the
3030 SKE protocol specification.
3032 * Added better GMP detection to configure.in.pre. A patch
3035 Fri Jul 20 13:16:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3037 * Fixed a minor bug in SKE that might cause some problem on
3038 some platforms. Affected file lib/silcske/silcske.c.
3040 * Added the cookie checking for initiator in the SKE. It checks
3041 that the responder returns the sent cookie unmodified. The
3042 affected file is lib/silcske/silcske.c. Added new SKE
3043 error type INVALID_COOKIE that can be sent during the
3044 negotiation. Fixed some memory leaks as well.
3046 * Added the "invalid cookie" error message to Irssi SILC client's
3049 Thu Jul 19 21:44:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3051 * Added `task_max' field to the SilcClientParams to indicate
3052 the maximum tasks the scheduler can handle. If set to zero,
3053 default values are used. Affected file lib/silcclient/silcapi.h.
3055 * Fixed memory leaks in silc_client_close_connection. Affected
3056 file lib/silcclient/client.c.
3058 * Added silc_client_del_client_entry to client library to free
3059 all memory of given client entry. Affected file is
3060 lib/silcclient/idlist.[ch].
3062 * Added new functions silc_client_del_channel and
3063 silc_client_del_server to delete channel and server entries.
3064 Affected file lib/silcclient/[silcapi.h/idlist.c].
3066 * Removed silc_client_del_client_by_id from silcapi.h.
3068 * Fixed the INFO command to return the server's own info
3069 correctly when querying by Server ID. Affected file is
3072 Thu Jul 19 14:47:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3074 * Removed the non-blocking settings in WIN32 code in the
3075 silc_sock_[read/write] and added SleepEx instead. Affected
3076 file lib/silcutil/win32/silcwin32sockconn.c. The availability
3077 of input data is now checked with FIONREAD and ioctlsocket.
3079 Wed Jul 18 18:34:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3081 * Call silc_schedule_task_del_by_context in the
3082 silc_protocol_cancel instead of silc_schedule_task_del_by_callback.
3083 Affected file lib/silccore/silcprotocol.c.
3085 * Call silc_protocol_cancel for active protocols in the
3086 silc_server_close_connection if the funtion
3087 silc_server_free_sock_user_data has not been called.
3088 Affected file silcd/server.c.
3090 * Generic tasks cannot be deleted using the del_by_fd
3091 task deleting function since generic tasks does not match
3092 any specific fd. Affected file lib/silcutil/silcschedule.[ch].
3094 * Added a notion to SILCOPER help file that the SILCOPER works
3095 only on router server, not on normal server.
3097 Wed Jul 18 09:40:04 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3099 * Added for WIN32 support for the new scheduler as well.
3100 Affected file lib/silcutil/win32/silcwin32schedule.c.
3102 * Fixed the SHA1 implementation to work on various platforms.
3104 Tue Jul 17 23:04:10 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3106 * Rewrote the SILC Scheduler entirely. Removed the old SILC Task
3107 API. It is part of the scheduler now. Everything else is
3108 as previously but some functions has changed their names.
3109 Checkout the lib/silcutil/silcschedule.h for the interface.
3110 Updated all applications to use the new interface. Affected
3111 files are lib/silcutil/silcschedule.[ch].
3113 Tue Jul 17 16:53:30 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3115 * Found a bug in the SKE implementation. The HASH value,
3116 specified by the protocol, was not computed correctly. The
3117 public key of the responder was not added to the computation
3118 even though it is mandatory. Affected file lib/silcske/silcske.c.
3119 This unfortunately causes incompatibilities with older
3120 clients and servers.
3122 * Added WIN32 specific network init and uninit functions:
3123 silc_net_win32_init and silc_net_win32_uninit to init and uninit
3124 the Winsock2. Affected file lib/silcutil/silcnet.h and
3125 lib/silcutil/win32/silcwin32net.c.
3127 * Set the socket always to nonblocking mode on WIN32 after
3128 reading data or writing data. Affected file is
3129 lib/silcutil/win32/silcwin32sockconn.c.
3131 Mon Jul 16 22:55:26 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3133 * Fixed various compilation problems under WIN32. Affected
3134 files lib/silcutil/win32/silcwin32thread.c and
3135 lib/silcutil/win32/silcwin32schedule.c.
3137 * Removed all _internal.h #includes from public header
3138 files. Internal headers must never be included from
3141 Removed also the lib/silcske/payload_internal.h file.
3143 * All include files that may be needed (public and some others
3144 included by the public headers) by application developers are
3145 now copied to the ./includes directory. It does not copy any
3146 internal headers. Affected file Makefile.defines.pre and all
3147 Makefile.am's under lib/ and subdirs.
3149 Thu Jul 12 17:49:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3151 * Do not change the ~/.silc directory's permissions automatically.
3152 Affected file irssi/src/silc/core/clientutil.c.
3154 Thu Jul 12 10:18:40 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3156 * Do not cancel the protocol in silc_server_close_connection
3157 it might cause recursion. Now cancelled in the function
3158 silc_server_free_sock_user_data. Affected file silcd/server.c.
3160 * Fixed the silc_server_remove_clients_by_server to regenerate
3161 the channel keys correctly finally. Added also new function
3162 silc_server_remove_clients_channels to actually do it.
3163 Affected file silcd/server.c.
3165 * Fixed the silc_server_new_channel to not crash by giving
3166 wrong router to the new channel. Affected file is
3167 silcd/packet_receive.c.
3169 Wed Jul 11 18:31:57 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3171 * Added SilcClientParams structure to the lib/silcclient/silcapi.h
3172 which is given as argument to the silc_client_alloc now.
3173 It can be used to configure the client and set various parameters
3174 that affect the function of the client.
3176 * The USERS command in server did not check whether the channel
3177 is private or secret. Affected file silcd/command.c.
3179 * Added new argument to the USERS command in protocol specification.
3180 The USERS command now can take the channel name as argument
3181 as well. Added support for this in client and server and
3182 updated the protocol specs.
3184 * Completed the GETKEY command in client. It can be now used
3185 to fetch also servers public key not only some clients.
3186 Affected files lib/silcclient/command[_reply].c.
3188 * Added silc_client_get_server to return server entry by the
3189 server name. Affected files lib/silcclient/silcapi.h and
3192 * Redefined the IDENTIFY command in protocol specification to be
3193 more generic. It now can be used to query information about
3194 any entity in the SILC Network, including clients, servers and
3195 channels. The query may be based either the entity's name
3196 or the ID. Added support for this in both client and server.
3198 Affected files silcd/command.c and lib/silcclient/command.c
3199 and command_reply.c.
3201 * Optimized the WHOIS and WHOWAS commands in the server. Removed
3202 the _from_client and _from_server functions. Affected file
3205 * Added silc_client_get_channel_by_id_resolve to the file
3206 lib/silcclient/silcapi.h to resolve channel information by
3207 its ID. Added also silc_client_get_channel_by_id that
3208 does not resolve it from the server.
3210 Tue Jul 10 18:05:38 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3212 * Added SilcServerEntry context into the client library
3213 to represent one server. The INFO command now allocates
3214 these to save the resolved server info. For now on the
3215 client library will also keep information about servers,
3216 connected and resolved with INFO.
3218 The INFO command now allocates the SilcServerEntry context
3219 and saves the server info there. The COMMAND_REPLY in
3220 the INFO now returns the parameters to application in
3221 same order as defined in the protocol specification.
3223 The entries are cached in the client->server_cache.
3225 * The INFO command is now issued after received the Client ID
3226 from the server. Affected file lib/silcclient/client.c.
3228 * The CMODE_CHANGE notify may now return also an SilcServerEntry
3229 to the application as the mode changer might be server.
3230 It is guaranteed that NULL is not returned anymore to the
3231 application. Affected file lib/silcclient/client_notify.c.
3233 The ID Type is now also passed to the application so that
3234 it can check whether the returned entry is SilcClientEntry
3237 Added new function silc_client_get_server_by_id to return
3238 the server entry by ID. Affected files are the
3239 lib/silcclient/silcapi.h and lib/silcclient/idlist.c.
3241 * Do not create the channel in the Irssi SILC Client when issuing
3242 the JOIN command but when received the sucessful JOIN command
3243 reply. Otherwise the channel might get created even though we
3244 could not join it. The Affected file is
3245 irssi/src/silc/core/[silc-channels.c/client_ops.c].
3247 * Fixed a channel joining bug in router. The router must also
3248 check the channel modes, invite and ban lists etc. when serving
3249 the JOIN command sent by normal server. Affected file is
3250 silcd/command.c. The router now resolves the client's
3251 information from the server who sent the JOIN command if it
3252 does not know it, and processes the JOIN command only after
3255 * Changed the SilcCommandCb to take new argument; void *context2.
3256 Affected file lib/silccore/silccommand.h
3258 The second argument in the command callbacks in the server now
3259 includes the SilcServerCommandReplyContext if the command was
3260 called as pending command callback from the command reply.
3261 Otherwise it is NULL. When called as pending the status of the
3262 command reply will be checked and if it was erronous the
3263 error will be sent to the original sender of the command.
3264 This way the client always receives the error messages even
3265 though the server was actually the one who received the error
3266 when it resent the command to router, for example. Affected
3267 files silcd/command[_reply].[ch].
3269 * Fixed sending WHOWAS command's error message to client if
3270 the requested client could not be found. It was missing.
3273 * Changed the CMODE and CUMODE commands reply arguments in the
3274 protocol specification. The Channel ID is now sent in both
3275 of the commands to identify the channel. Implemented this
3276 new feature to the client and server. Affected files
3277 lib/silcclient/command_reply.c and silcd/command.c.
3279 * Made better checks for invite and ban lists in the JOIN
3280 command in server. Affected file silcd/command.c.
3282 Mon Jul 9 18:28:34 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3284 * The server now performs the incoming host IP/DNS lookup
3285 using the silc_socket_host_lookup and thus does not block
3286 the server anymore. Affected file silcd/server.c.
3288 * Completed the multi-thread support for SILC Scheduler in
3289 the lib/silcutil/silcschedule.c.
3291 * Fixed the configure.in.pre to detect the pthread correctly
3294 * Fixed a deadlock in silc_task_queue_wakeup in the file
3295 lib/silcutil/silctask.c.
3297 Mon Jul 9 13:40:03 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3299 * Added new function silc_schedule_wakeup that is used in
3300 multi-threaded environment to wakeup the main thread's
3301 schduler. It needs to be used when a thread adds a new task
3302 or removes a task from task queues. After waking up, the
3303 scheduler will detect the task queue changes. If threads
3304 support is not compiled in this function has no effect.
3305 Implemented the wakeup mechanism to both Unix and WIN32
3306 systems. Affected files are lib/silcutil/silcschedule.[ch],
3307 lib/silcutil/unix/silcunixschedule.c and the
3308 lib/silcutil/win32/silcwin32schedule.c.
3310 * Added new function silc_task_queue_wakeup to wakeup the
3311 scheduler by the specified task queue. Affected file
3312 lib/silcutil/silctask.[ch].
3314 * The silc_socket_host_lookup_start now wakes up the scheduler
3315 after adding the timeout task. Affected file is
3316 lib/silcutil/silcsockconn.c.
3318 * The silc_socket_host_lookup is synchronous now if the threads
3319 support is not compiled in. However, the callback is still
3320 called asyncronously through the scheduler, anyway. Affected
3321 file lib/silcutil/silcsockconn.c.
3323 Mon Jul 9 00:24:45 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3325 * Added new function silc_socket_host_lookup to perform
3326 asynchronous IP and FQDN lookups for the socket connection.
3327 Affected files lib/silcutil/silcsockconn.[ch].
3329 Sun Jul 8 18:44:53 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3331 * Added SILC_MUTEX_DEFINE to define the mutex on environments
3332 that may or may not compile the mutex support in.
3334 Changed the silc_mutex_alloc interface. It allocates the
3335 mutex now to the sent pointer and returns TRUE or FALSE.
3337 Affected file lib/silcutil/silcmutex.h.
3339 * Wrote the SILC Task Queue interface to support multi-threads.
3340 Affected file lib/silcutil/silctask.[ch].
3342 * Wrote the SILC Scheduler to support multi-threads. Affected
3343 file lib/silcutil/silcschedule.c.
3345 Sun Jul 8 11:16:01 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3347 * Implemented the SILC Mutex API and SILC Thread API for WIN32
3348 in lib/silcutil/win32/.
3350 Sun Jul 8 00:18:15 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3352 * Defined SILC Mutex API and SILC Thread API and implemented
3353 them for Unix. Affected files are
3354 lib/silcutil/silcmutex.h, lib/silcutil/silcthread.h,
3355 lib/silcutil/unix/silcunixmutex.c and
3356 lib/silcutil/unix/silcunixthread.c.
3358 Sat Jul 7 14:40:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3360 * Fixed the silc_server_remove_clients_by_server's channel
3361 key re-generation. The hash table handling was incorrect
3362 and would not work with many channels. Affected file is
3365 * Fixed some memory leaks around the server code.
3367 * Rewrote the silc_server_get_users_on_channel to support IPv6
3368 based Client ID's. Affected file silcd/server.c.
3370 * Defined the SILC_MESSAGE_FLAG_SIGNED to the protocol
3371 specification. However, a separate document must be written
3372 to define the detailed signing procedure and the payload
3373 associated with the flag. Defined the flag to the
3374 lib/silccore/silcchannel.h as well.
3376 Fri Jul 6 18:26:31 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3378 * Changed the dynamic tables to static size tables in the
3379 lib/silccrypt/silchmac.c.
3381 * Removed GCC dependencies from the code. A patch by cras.
3383 Fri Jul 6 09:39:35 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3385 * Do not show the error "Error receiving packet bla bla"
3386 in server if it really was not an error (-2 means that reading
3387 is pending). Affected file silcd/server.c.
3389 Thu Jul 5 21:22:32 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3391 * Fixed a possible crash in silc_server_remove_clients_by_server
3392 in silcd/server.c. Fixed there also some memory leaks.
3394 * Fixed the silc_idlist_replace_client_id. It could replace
3395 wrong key in the hash table. Affected file silcd/idlist.c.
3397 * Do not check whether there are global users on the channel
3398 if the channel->global_users is FALSE. Affected functions
3399 silc_server_remove_from_one_channel and
3400 silc_server_remove_from_channels in silcd/server.c. Also,
3401 do not check if the removed client is local as we can be
3402 sure that global client was not removed from the channel
3403 and checking for global users is not needed.
3405 * The silc_server_remove_clients_by_server now re-generates
3406 the channel keys correctly for those channels that had
3407 clients removed from them. Affected file silcd/server.c.
3409 Tue Jul 3 11:39:20 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3411 * Found the reason of random crashes in the server. We weren't
3412 ignoring the SIGPIPE signal (which can be sent in write())
3413 and it crashed the server. Affected file silcd/silcd.c.
3415 Fri Jun 29 20:05:25 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3417 * Assure that sock->user_data is not NULL in the function
3418 silc_server_packet_send in silcd/packet_send.c.
3420 * Disconnect the remote connection if it could not be added
3421 to any ID lists in the server. The affected file is
3424 * Check in silc_server_packet_send[_real/dest] that the
3425 socket is not disconnecting and ignore the data if it is.
3426 Affected file silcd/packet_send.c.
3428 * Define inline to __inline on native WIN32 compilation.
3429 Affected file includes/silcwin32.h.
3431 * Added some explicit type casts for inline code since MSVC
3432 require them. Affected files lib/silcutil/silcbuffer.h,
3433 lib/trq/silcdlist.h and lib/trq/silclist.h.
3435 * Print warning in log files from now on if the packet
3436 decryption fails. Affected file silcd/server.c.
3438 Thu Jun 28 21:30:39 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3440 * Changed the `say' client operation's interface to accept
3441 new `type' argument to indicate the type of the message sent
3442 by the library. The application may filter the library's
3443 messages according the type. The affected file is the
3444 lib/silcclient/silcapi.h.
3446 * Added two new functions to lib/silcclient/silcapi.h:
3447 silc_client_del_client and silc_client_del_client_by_id.
3448 Affected file lib/silcclient/idlist.c.
3450 * Moved the clientincludes.h from includes/ to silc/ and
3451 serverincludes.h from includes/ to silcd/.
3453 * The modes for the CMODE and CUMODE are now passed as
3454 uint32 for application with COMMAND_REPLY. The affected
3455 file is lib/silcclient/command_reply.c.
3457 Wed Jun 27 22:24:47 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3459 * /WHOIS without arguments shows client's own information.
3460 Affected file lib/silcclient/command.c.
3462 * Changed PING to not accept any arguments. The specs
3463 says that client can ping only the connected server so
3464 requiring an argument is not needed. Affected file is
3465 lib/silcclient/command.c.
3467 Wed Jun 27 00:10:33 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3469 * Fixed a fatal bug in private message sending and reception
3470 encryption and decryption when using private message keys.
3471 The implementation was incorrect and did not follow the
3472 specification. It causd that some of the message were
3473 lost since it did not use the sending and receiving keys
3474 as the protocol suggests. This has been fixed and will cause
3475 incompatibilities with older clients when sending private
3476 message encrypted with private message keys. Affected files
3477 lib/silcclient/client_prvmsg.c, lib/silcclient/client_keyagr.c
3478 and various other in Irssi SILC Client.
3480 Added `responder' boolean argument to the functions
3481 silc_client_add_private_message_key[_ske] to indicate when
3482 the key is added as responder or initiator of the key
3485 Tue Jun 26 19:23:07 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3487 * Removed the silc_ske_check_version function and created
3488 a SilcSKECheckVersion callback. Added also a function
3489 silc_ske_set_callbacks that is now used to set all SKE
3490 callbacks. The callback functions are not given to
3491 the SKE functions anymore, but this function is used to
3494 * Fixed the WIN32 DLL generation in lib/Makefile.am.pre.
3496 * Added `silc_version' argument to the silc_client_alloc
3497 to define the version of the application for the library.
3498 The library will use the version string to compare it
3499 against the remote host's (usually a server) version
3500 string. Affected file lib/silcclient/silcapi.h
3502 * Added the KE protocol context to Key Agreement context
3503 in client library so that we can abort the SKE if it
3504 is in process when we get timeout. Affected file is
3505 lib/silcclient/client_keyagr.c.
3507 * Do not resolve the client ID forever if it returns in the
3508 first time that such client does not exist. This was done
3509 for example with private message. Affected file is
3510 lib/silcclient/client_prvmsg.c.
3512 Mon Jun 25 21:42:51 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3514 * Do not add regex.h for WIN32. The affected file
3515 includes/silcincludes.h.
3517 * Added WIN32 DLL generation to lib/Makefile.am.pre. It might
3518 not work yet 100%. It generates the DLL's automatically
3519 when compiling with --with-win32 under cygwin.
3521 Sun Jun 24 19:49:23 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3523 * lib/contrib/regex.c is not compiled on WIN32.
3525 * Added silc_net_get_socket_opt function to the
3526 lib/silcutil/silcnet.h.
3528 * Added includes/silcwin32.h for WIN32 specific includes
3531 * Do not use ptime structure or any of the posix process
3532 functions on WIN32 in lib/silccrypt/silrng.c.
3534 * Added silc_gettimeofday to provide generic function
3535 for struct timeval on all platforms. Added the function
3536 to lib/silcutil/silcutil.h.
3538 Sun Jun 24 12:19:52 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3540 * Moved the lib/silccore/silcsockconn.[ch] to the utility
3541 library as they clearly belong there. As a plus side we
3542 can make the actual socket connection routines platform
3545 Added also new generic function silc_socket_read and
3546 silc_socket_write (that used to be silc_packet_[read/write].
3547 The implementation of these are platform specific.
3549 * Added WIN32 specific routines of silc_socket_[read/write]
3550 to lib/silcutil/win32/silcwin32sockconn.c.
3552 Sat Jun 23 16:01:00 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3554 * Added preliminary support for native WIN32 compilation under
3555 cygwin (using the -mno-cygwin option for GCC) to the
3556 ./configure.in.pre. The --with-win32 now prepares the
3557 compilation for native WIN32.
3559 * Rewrote the SILC Scheduler interface in the file
3560 lib/silcutil/silcschedule.h. The scheduler is now context
3561 based and does not have anymore any global static scheduler.
3562 Moved the Unix scheduler to the lib/silcutil/unix/ directory
3563 and created lib/silcutil/win32 directory for WIN32 based
3566 * Added Unix specific network routines to the
3567 lib/silcutil/unix/silcunixnet.c and the old
3568 lib/silcutil/silcnet.c includes now only generic routines.
3570 Added WIN32 specific network routines to the
3571 lib/silcutil/win32/silcwin32net.c.
3573 * Added Unix specific utility functions from the
3574 lib/silcutil/silcutil.c to lib/silcutil/unix/silcunixutil.c.
3576 * Added WIN32 SILC Scheduler to the file
3577 lib/silcutil/win32/silcwin32schedule.c. The code is of course
3580 Fri Jun 22 10:44:14 EEST 2001 Pekka Riikonen <priikone@silcnet.org>
3582 * Do not handle JOIN notify in the server if the target client
3583 is not registered (idata->registered == FALSE). The affected
3584 file is silcd/packet_receive.c.
3586 * Update the nickrec->founder in event_cumode in the Irssi SILC
3587 client. Affected file irssi/src/silc/core/silc-channels.c.
3589 * Fixed the CUMODE_CHANGE notify handling in the server when
3590 server and router are announcing their clients on channels.
3591 Now the mode changes are saved and notified correctly. The
3592 affected file is /silcd/packet_receive.c.
3594 * Fixed silc_idlit_replace_[server/client/channel]_id functions.
3595 They really did not replace the cache entry in the ID Cache.
3596 Now they do that. Affected file silcd/idlist.c.
3598 * Fixed the KICK notify handling in the Irssi SILC client to
3599 update the channel records so that the kicked client does not
3600 appear to be on the channel. The affected file is
3601 irssi/src/silc/core/silc-channels.c.
3603 * Always update the conn->current_channel when executing command
3604 on a channel. Affected file irssi/src/silc/core/silc-servers.c.
3606 * Fixed the KILL notify handling in Irssi SILC client to remove
3607 the killed client on all channels.
3609 Thu Jun 21 17:10:08 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3611 * Fixed the silc_parse_command_line to remove extra spaces
3612 from the start and end of the arguments. Affected file is
3613 lib/silcutil/silcutil.c.
3615 * Cancel and free any active protocol in the function
3616 silc_server_close_connection. Affected file silcd/server.c.
3618 * Cancel and free any active protocol in the function
3619 silc_client_close_connction. Affected file is
3620 lib/silcclient/client.c.
3622 * Do not execute the KILL command for clients that are in
3623 history (ie. they are not in the network). Affected file is
3626 * Fixed KILL notify handling, client does not crash anymore.
3627 Affected file irssi/src/silc/core/silc-channels.c.
3629 * Reduced the default packet buffer size from 2048 to 1024 in
3630 lib/silccore/silcpacket.c.
3632 * Added SILC_SKE_STATUS_FREED SKE status type and a reference
3633 counter to the SKE context that is incresed when the SKE library
3634 performs async operation outside the library. If the outside
3635 process frees the SKE context and FREED status will be set
3636 and the library will detect after the sync operation that the
3637 libary is freed. The affected files are
3638 lib/silcske/silcske[_status].[ch].
3640 * Resolve the client entry information in the function
3641 silc_client_channel_message to assure that NULL pointer is not
3642 passed as client entry to the application. */
3644 * Fixed the task timeout calculation to assure that there is
3645 never negative timeouts. The affected file is
3646 lib/silcutil/silcschedule.c.
3648 * Fixed the channel user mode notification sending in server.
3649 It was sent point-to-point to the router (or to server by router)
3650 but it needs to be destined to a channel. The routines now
3651 supports sending the channel user mode notifys to the channels
3652 when announcing clients and channels. Affected files are
3653 silcd/server.c and silcd/packet_receive.c.
3655 * Fixed the CHANNEL_CHANGE notify handling in the client libary.
3656 It did not actually replace the old channel entry in the cache.
3657 Affected file lib/silcclient/client_notify.c.
3659 Tue Jun 19 22:10:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3661 * Fixed a possible crash in silc_packet_send_prepare. It now
3662 assures always that there is enough space in the buffer and
3663 at the tail area of the buffer (for MAC).
3665 Fixed the inbound buffer reallocation in silc_packet_read.
3666 It was old code and did not handle the reallocation correctly.
3669 The affected file is lib/silccore/silcpacket.c.
3671 * Fixed buffer overflow in silc_parse_nickname in the file
3672 lib/silcutil/silcutil.c.
3674 Tue Jun 19 13:40:09 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3676 * make install generates new server keys only if there is not
3679 Mon Jun 18 18:49:07 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3681 * Set SILC_MESSAGE_FLAG_NOREPLY when sending the away message.
3682 Added check that if the NOREPLY is set then we will not send
3683 the away message. This avoids infinite loop of away messages
3684 if both clients are away. The affected file is
3685 lib/silcclient/client_prvmsg.c.
3687 * Fixed client crash if /NICK was given without arguments.
3688 Affected file lib/silcclient/command.c.
3690 * Server does not send the invite list in INVITE command back
3691 to the client if the list was not altered. Added this notion
3692 to the protocol spec as well. Affected file silcd/command.c.
3694 Fixed possible crash in INVITE command by checking the
3695 value of silc_server_get_client_route command.
3697 * Fixed the INVITE notify type handling. The arguments are now
3698 taken in correct order and client does not crash. The affected
3699 file is irssi/src/silc/core/silc-channels.c.
3701 Removed the "Inviting xxx to channel" message from the
3702 client library away and let the application handle it.
3703 Affected file lib/silcclient/command.c. Added that message
3704 to Irssi SILC client's message formats.
3706 * Fixed CMODE command crash in client. It now checks the
3707 amount of arguments correctly and does not crash. The affected
3708 file is lib/silcclient/command.c.
3710 * Do not create new channel automatically in silc_channels_join
3711 but check whether the channel by that name already exists.
3712 Affected file irssi/silc/core/silc-channels.c.
3714 * Do not send the SERVER_SIGNOFF to router if the disconnected
3715 entity was the router. Affected file silcd/server.c.
3717 * Added the handling of the SERVER_SIGNOFF notify to the Irssi
3718 SILC client as it was missing from there.
3720 Added the handling of the KICK notify to the Irssi SILC client
3721 as it was missing. Added "you have been kicked" message to
3722 Irssi SILC client's message modules formats.
3724 Added the handing of the KILL notify to the Irssi SILC client
3725 as it was missing. Added the kill message module formats
3728 The affected file is irssi/src/silc/core/silc-channels.c.
3730 * The router did not save the channel mode the server announced.
3731 Affected file silcd/packet_receive.c.
3733 * Fixed a possible crash in INFO command in server. If the
3734 server did not provide the server info it crashed. Affected
3735 file silcd/command.c.
3737 Sun Jun 17 15:26:05 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3739 * Fixed the GETKEY command in the server to check also the
3740 global list. Otherwise the GETKEY would not work correctly
3741 in normal SILC server. Affected file silcd/command.c.
3743 Sat Jun 16 18:00:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3745 * Fixed GETKEY crash, it crashed if the command did not succseed.
3747 Tue Jun 12 21:36:18 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3749 * Redefined the SILC MP API in lib/silcmath/silcmp.h. The API
3750 is now real and not just an macro interface to GMP.
3752 Removed the entire GMP from the source tree and imported new
3753 NSS MPI library instead. Reason for removing GMP is that it is
3754 extremely large and compiles extremely slow. The NSS MPI
3755 is only a few files and compiles in less than 10 seconds.
3756 The speed is also about the same as GMP. The MPI is imported
3757 to lib/silcmath/mpi.
3759 If the system has GMP installed we will still use the GMP.
3760 If it is not then the NSS MPI will be compiled.
3762 Mon Jun 11 18:07:24 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3764 * Merged a long nickname (127 characters long) crash bugfix from
3765 Irssi CVS tree. Affected file irssi/src/core/misc.c.
3767 * Merged a freed memory reference bugfix from Irssi CVS tree.
3768 Affected file irssi/src/core/commands.c.
3770 Sun Jun 10 16:08:35 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3772 * Added the server's public key sving and verification to the
3773 server when performing the SKE. This was missing and the
3774 remote server's (or router's) public key was accepted without
3775 checking whether we have it previously or trust it at all.
3776 Affected file silcd/protocol.c.
3778 Sat Jun 9 20:17:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3780 * Check in the silc_server_timeout_remote if protocol is active
3781 and make sure that the protocol's final callback is called so
3782 that all memory if freed. Affected file silcd/server.c.
3784 Sat Jun 9 12:51:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3786 * silc_server_whois_send_reply crashed the server if the nickname
3787 was 127 characters long. Affected file silcd/command.c.
3789 Thu Jun 7 16:29:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3791 * Added sanity check to the silc_server_new_client. If the hostname
3792 is provided inside username then check that the provided hostname
3793 really is the same as the resolved one. If the hostname was not
3794 resolved then check it from the public key. Affected file is
3795 silcd/packet_receive.c.
3797 * Fixed a fatal bug in Irssi SILC client. Do not send QUIT command
3798 if the server disconnected us and the connection is not valid
3799 anymore. Affected file irssi/src/silc/core/silc-channels.c.
3801 * Moved the silc_client_[chmode|chumode|chumode_char] away from
3802 the library to the lib/silcutil/silcutil.[ch].
3804 Thu Jun 7 08:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3806 * Close log file after open. Affected file
3807 lib/silcutil/silclog.c.
3809 * Check whether sock == NULL in silc_client_send_packet and return
3810 if it is. Affected file lib/silcclient/silcclient.c.
3812 * Check rec->entry == NULL in the Irssi SILC Client before
3813 sending the channel message. Affecte file is
3814 irssi/src/silc/core/silc-servers.c.
3816 Tue Jun 5 08:08:21 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3818 * Merged a splitted window bugfix from Irssi CVS tree. The
3819 affected file is irssi/src/fe-text/textbuffer-view.c.
3821 * Fixed the ME, ACTION and NOTICE printing in Irssi Client.
3822 It did not print nickname.
3824 * Improved the distributions system a bit.
3826 Mon Jun 4 17:57:16 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3828 * Merged /WINDOW bugfix from irssi CVS tree. Affected file is
3829 irssi/src/fe-text/gui-window.c.
3831 * Fixed a fatal bug in Irssi SILC client. Crashed if sent message
3832 to in-active server. The affected file is
3833 irssi/src/silc/core/client_ops.c.
3835 * Resolve the client in USERS command reply if the entry does
3836 not have username resolved. The affected file is
3837 lib/silcclient/command_reply.c. Also, changed the IDENTIFY
3838 command to WHOIS command to really resolve stuff. The USERS
3839 is not used any more in any critical section so WHOIS can
3840 be used even though it might be slower than IDENTIFY.
3842 * Changed the lib/silcutil/silchashtable.h header to ROBODoc
3845 Sun Jun 3 14:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3847 * Changed the protocol API a bit more consistent in the
3848 lib/silccore/silcprotocol.[ch].
3850 * Changed the following headers to ROBODoc format:
3852 lib/silccore/silcpayload.h
3853 lib/silccore/silcprotocol.h
3854 lib/silccore/silcsockconn.h
3856 All core library headers are now formatted.
3858 Sat Jun 2 10:45:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3860 * Fixed a bug in Irssi SILC client; do not show that you are
3861 server/router operator if you really are not. Affected file is
3862 irssi/src/silc/core/client_ops.c.
3864 * Renamed silc_command_free_payload to silc_command_payload_free.
3865 Affected file lib/silccore/silccommand.h
3867 * Added silcmath.h to include the prototoypes of various routines
3868 in the lib/silcmath. Removed the old modinv.h, mpbin.h and
3871 * Changed the following headers to ROBODoc format:
3873 lib/silccore/silcchannel.h
3874 lib/silccore/silccommand.h
3875 lib/silccore/silcid.h
3876 lib/silccore/silcidcache.h
3877 lib/silccore/silcmode.h
3878 lib/silccore/silcnotify.h
3879 lib/silccore/silcpacket.h
3880 lib/silcmath/silcmath.h
3882 Fri Jun 1 22:19:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3884 * Added checking to the server code not to start the server if
3885 ciphers and stuff are not configured properly. Affected files
3886 silcd/serverconfig.[h] and silcd/server.c.
3888 * Changed the layout of the header files of the public interfaces
3889 in the SILC libraries. The new layout supports ROBODoc
3890 documentation tool (and some others) so that it is easy to create
3891 a library reference manual. All the other headers and source
3892 code must still follow the CodingStyle document. Also source
3893 code must not include these ROBODoc stuffs, only the headers.
3894 Furthermore, all public interface headers must now be named
3895 by using `silc' prefix, example: silcapi.h, silccipher.h.
3896 Some files were renamed due to this. All the other headers
3897 must not be used as public interfaces. I will update the
3898 CodingStyle document later. Changed following headers, so far:
3900 lib/silcclient/silcapi.h
3901 lib/silccore/silcauth.h
3902 lib/silccore/silcprivate.h
3903 lib/silccrypt/silcdh.h
3905 Fri Jun 1 10:28:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3909 * Removed silc_client_packet_send_flush from the client library
3910 as it is not needed. Affected file lib/silcclient/client.[ch].
3912 * Added printing of message of unresolved authentication method
3913 to the Irssi SILC client. Added it to the module formats.
3914 Removed the same message from the client library.
3916 Thu May 31 13:57:33 CEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3918 * Added new distribution feature, DISTLABEL. Every distribution
3919 can define own preprocessor label that can be used in the
3920 source code. For example: #ifdef SILC_DIST_CLIENT. Affected
3921 file distributions, acconfig.h.pre and prepare.
3923 Tue May 29 22:16:40 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3925 * Added Makefile.defines_int to include the actual definitions
3926 for Makefile.defines.in. Tested the new distribution system,
3927 created distributions and tested installation.
3929 * Added AWAY message printing to the Irssi SILC client. Added
3930 the messages to the irssi/src/fe-common/silc/module-formats.[ch].
3932 * Added SCONNECT command to call the SILC's CONNECT command.
3933 Cannot use CONNECT directly since Irssi uses that internally.
3934 Affected file irssi/src/silc/core/silc-servers.c.
3936 Added ACTION local command. It is same as ME command but takes
3937 the channel as mandatory argument.
3939 Rewrote some of the Irssi's help files to suite for SILC
3942 Mon May 28 19:05:22 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3944 * Added Makefile.defines[.in] that should for now on be included
3945 in all Makefile.am file in the source tree. That file includes
3946 all common compilation definitions for SILC source tree.
3948 Mon May 28 10:30:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3950 * Minor changes to the ./prepare script to change the package
3951 name according the distribution name to the configure.in.
3953 Sun May 27 22:24:57 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3955 * Created new distribution system. Added file `distributions'
3956 that defines all the distributions that can be created out of
3957 the SILC source tree. The ./prepare script now reads that
3958 file to determine how to prepare the distributions. The
3959 first argument to the ./prepare is the name of the distribution
3960 and second is the version of the distribution. If given
3961 without arguments it creates the default (toolkit) distribution
3962 with the default version (defined in ./prepare).
3964 All Makefile.am files that are subject to the distributions
3965 are now named as Makefile.am.pre. These are ./Makefile.am
3966 and lib/Makefile.am. Others may be changed later.
3968 Sun May 27 15:57:17 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3970 * Added invite list, ban list, some key management and connection
3971 error message printing to module formats in the Irssi SILC client.
3973 * Added new silc_client_set_away_message to set the away message
3974 that is back to the person who sent private message. The
3975 affected file lib/silcclient/silcapi.h and the
3976 lib/silcclient/client_prvmsg.c.
3978 Sun May 27 12:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3980 * Fixed the private message sending in the Irssi SILC client,
3981 added local command KEY to the Irssi SILC client.
3983 Added key management and key agreement message formats to the
3984 irssi/src/fe-common/silc/module-formats.[ch].
3986 Added USERS (alias WHO) printing, server/router operator
3987 indication and LIST command printing to the module formats.
3989 Sat May 26 17:43:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3991 * Fixed channel joining notify handling, cumode notify handling
3992 from Irssi SILC client.
3994 * Added SILC specific module-formats to the Irssi SILC client so
3995 that SILC specific message hilighting, colors etc is possible.
3996 Affected file irssi/src/fe-common/silc/module-formats.[ch].
3998 Added channel mode, channel user mode, actions, notices,
3999 whois and whowas printing to the the module-formats.c.
4001 * Fixed a bug in channel deletion in the server. The channel
4002 is not left to the cache even if the channel founder auth mode
4003 is set when there are no users anymore on the channel. Affected
4004 file silcd/server.c.
4006 * The silc_net_localhost now resolves the entire hostname including
4007 the domain name. Affected file lib/silcutil/silcnet.c.
4009 Sat May 26 12:13:37 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4011 * Changed the ask_passphrase client operation to be ascynchronous.
4012 It has now a completion callback and a context that the
4013 application must call after it has got the passphrase from
4014 the user. Affected files lib/silcclient/silcapi.h,
4015 lib/silcclient/protocol.c, lib/silcclient/command.c and
4018 Added SilcAskPassphrase callback that the application calls
4019 to deliver the passphrase to the library.
4021 * Changed the SKE protocol's SilcSKEVerifyCb to be asynchronous.
4022 The public key verification and especially a certificate
4023 verification is asynchronous procedure.
4025 Added new SILC_SKE_STATUS_PENDING status to indicate the
4026 request is pending and a callback will be called to finalize
4029 Added also SILC_SKE_STATUS_PUBLIC_KEY_NOT_PROVIDED status to
4030 indicate that remote end did not send its public key (or
4031 certificate), even though we require it. Added check for this
4032 condition in the SKE. This was a security bug, now fixed.
4034 Defined new SilcSKEVerifyCbCompletion callback that is called
4035 when the verification process is completed.
4037 The affected files lib/silcske/silcske_status.h and
4038 lib/silcske/silcske.[ch].
4040 * Changed the verify_public_key client operation to be async
4041 as well. Defined SilcVerifyPublicKey callback that is used to
4042 indicate the success of the public key verification process.
4044 Changed the server and client to use the new async client
4047 * Changed the Irssi SILC client's internal scheduler to be called
4048 twice as many times as it used to be. As a result the client
4049 should be a bit faster now. Affected file is
4050 irssi/src/silc/core/silc-core.c.
4052 * Added support to Irssi SILC client of asynchronous public key
4053 verification and passphrase inquiry. Affected file is
4054 irssi/src/silc/core/silc-core.c.
4056 Fri May 25 14:38:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4058 * Do not say "You have left channel %s" in client library.
4059 Moved it to the application. Affected files are
4060 lib/silcclient/command.c and silc/client_ops.c.
4062 * Fixed silc_client_get_clients. Command context was not
4063 duplicated and was freed memory in the callback. Affected
4064 file lib/silcclient/idlist.c.
4066 * Do not say "you are now talking..." on JOIN command in the
4067 client library. The appliation must handle it.
4069 * Do not say ".. changed topic to" in command reply in the
4070 client libary. The application must handle it.
4072 * Fixed TOPIC command sending in the client library.
4074 * Fixed a memory leak in silc_client_command_free in the file
4075 lib/silcclient/command.c.
4077 Thu May 24 19:08:55 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4079 * Imported a modified version of Irssi client to the source tree.
4080 The Irssi will be used to create a new client called
4081 Irssi SILC. Imported to irssi/.
4083 Added silc_core_init_finish function to the Irssi. Affected
4084 file irssi/configure.in.
4086 A lot changes in the Makefile.ams around the irssi tree.
4088 Tue May 22 22:23:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4090 * Do not rehash if the new size is same as the old size of the
4091 hash table, in the silc_hash_table_rehash*. The affected file
4092 lib/silcutil/silchashtable.c.
4094 * Replaced hash_table_del_by_context calls from the server
4095 (when channel->user_list and client->channels) to the
4096 hash_table_del as it is sufficient and faster.
4098 Tue May 22 17:27:16 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4100 * Added silc_hash_table_list, silc_hash_table_get and the
4101 SilcHashTableList structure to provide an alternative way to
4102 traverse the hash table. The affected files are
4103 lib/silcutil/silchashtable.[ch].
4105 * Changed the server's idlist routines to use the hash table
4106 routines to optimize the code.
4108 Mon May 21 21:46:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4110 * Replaced the client entry's `channel' list and channel entry's
4111 `user_list' list to hash tables for optimized lookup. Changed
4112 the code to use the hash table interface around the code.
4113 Affected file lib/silcd/idlist.[ch].
4115 * Added `auto_rehash' boolean argument to the function
4116 silc_hash_table_alloc to indicate whether the hash table should
4117 auto-rehash when it thinks is appropriate time. It will
4118 increase the hash table size if the there is twice as much
4119 entries in the table than the size of the table, and will
4120 decrease the size if there are twice as less entries than
4121 the size of the table.
4123 Mon May 21 09:51:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4125 * Fixed silc_xxx_get_supported to not crash at some circumstances.
4127 Sun May 20 13:45:58 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4129 * silc_idcache_purge_by_context deletes the entry now by context
4130 as it is supposed to do. Affected file lib/silccore/idcache.c.
4132 * Send the ERR_NO_SUCH_NICK in the WHOIS command reply if the
4133 client is not anymore valid (WHOWAS givens the info) and not
4134 the ERR_NO_SUCH_CLIENT_ID if the nickname still exists.
4136 Sat May 19 16:30:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4138 * Removed the `data' and `data_len' arguments from the ID Cache
4139 interfaces and added `name' argument. ID Cache does not handle
4140 anymore the binary data only a names associated with given ID.
4142 * When hashing a Client ID with silc_hash_id the entire ID is
4143 not hashed anymore, instead only the hash of the Client ID is
4144 hashed. This way we can access the Client ID from the cache
4145 with Client ID but with the hash of the ID (which is a hash of
4146 the nickname) as well without any difference in performance.
4148 Added also silc_idcache_find_by_id_one_ext to do one on one
4149 searching when we have the actual ID. Added also function
4150 silc_hash_client_id_compare. The affected files are
4151 lib/silccore/idcache.[ch] and lib/silcutil/silcutil.[ch].
4153 * When hashing the name associated with a ID it is always done
4154 in lowercase. This way we can access the cache without worrying
4155 about case-sensitivity, even though, for example nicknames are
4158 * Fixed a bug in server with channel message sending. It put
4159 wrong ID type as destination ID. The affected file
4160 silcd/packet_send.c.
4162 * silc_idcache_del_by_context now deletes from all hash tables
4163 by context. Affected file lib/silccore/idcache.c.
4165 Fri May 18 17:42:00 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4167 * Changed the client library to use the new ID Cache interface.
4168 Changes around the source tree.
4170 * Added silc_hash_table_rehash_ext to rehash with specific
4171 hash function. Affected file lib/silcutil/silchashtable.[ch].
4173 * Added silc_hash_string_compare to compare two strings in the
4174 hash table. Affected file lib/silcutil/silcutil.[ch].
4176 Fri May 18 11:18:45 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4178 * Added new function silc_idcache_del_by_context into the
4179 lib/silccore/idcache.[ch].
4181 * Changed the server's ID list routines to use the new ID Cache
4182 interface. Changes around the source tree.
4184 Fri May 18 08:35:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4186 * Added silc_hash_table_del[_by_context]_ext functions in to the
4187 lib/silcutil/silchashtable.[ch].
4189 Removed silc_hash_table_find_all* routines and added new
4190 silc_hash_table_find_foreach to replace them.
4192 Added silc_hash_table_replace_ext function as extended
4193 replacing function. Separated the simple hash table interface
4194 from the extended hash table interface in the file
4195 lib/silcutil/silchashtable.h.
4197 * Fixed minor bugs and changed it to use some of the new
4198 hash table functions in lib/silccore/idcache.c
4200 Thu May 17 18:15:12 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4202 * Added new function silc_hash_table_find_all to return all keys
4203 in the hash table by the specified key. As the hash table is
4204 collision resistant it also makes it possible to have several
4205 duplicate keys in the hash table. This function may be used to
4206 find all of the keys from the hash.
4208 Added user_context arguments to the SilcHashFunction,
4209 SilcHashCompare and SilcHashDestructor to deliver user specified
4212 Added new fuctions silc_hash_table_find[_all]_ext to do
4213 extended lookup with specified hash and compare functions and
4214 specified user contexts.
4216 Added new function silc_hash_table_add_ext to add the key
4217 with specified hash function and user context.
4219 Added new function silc_hash_table_foreach to traverse all
4220 entrys in the hash table. Added SilcHashForeach callback
4223 Added new function silc_hash_table_del_by_context to delete
4224 the entry only if the context associated with the key matches.
4226 Affected files are lib/silcutil/silchashtable.[ch].
4228 * Removed silc_hash_[server/client/channel]_id and added just
4229 silc_hash_id to the lib/silcutil/silcutil.[ch]. Added also
4230 silc_hash_id_compare to compare two ID's using as the hash table
4231 comparison function. Added also silc_hash_data to hash
4232 binary data and silc_hash_data_compare to compare it.
4234 * Removed silc_idlist_find_client_by_hash as it is not needed
4235 anymore. Affected file silcd/idlist.[ch].
4237 * Rewrote the entire ID Cache system (in lib/silccore/idcache.[ch])
4238 to use internally the SilcHashTable. The new ID Cache is a lot
4239 faster than the old one. Some of the ID Cache interface was also
4240 rewritten and obsolete and stupid functions were removed.
4242 Wed May 16 23:03:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4244 * Added entry_count field to the SilcHashTable to keep the number
4245 of the entries in the table. Implemented the function
4246 silc_hash_table_rehash. Added new function
4247 silc_hash_table_count. Affected file lib/silcutil/silchashtable.c.
4249 Fixed a minor bug in silc_hash_table_free.
4251 * Added silc_hash_string, silc_hash_uint, silc_hash_ptr,
4252 silc_hash_client_id, silc_hash_server_id and silc_hash_channel_id
4253 into the lib/silcutil/silcutil.[ch].
4255 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4257 * Implemented a collision resistant hash table into the
4258 lib/silcutil/silchashtable[ch]. See the header and the source
4259 for the SilcHashTable API.
4261 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4263 * Merged dotconf version 1.0.2 into lib/dotconf.
4265 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4267 * Do not compile anything in lib/silcsim/* if the SIM support
4268 is not enabled. The tree should now compile without problems
4271 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4273 * Compiled the SILC under cygwin. Compiled and tested briefly
4274 without problems. More tests needed. The SIMs didn't compile
4277 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
4279 * Fixed possible crash in silc_get_username in the
4280 lib/silcutil/silcutil.c.
4282 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4284 * Fixed a va_arg in silc/client_ops.c.
4286 * Oops, RC5 routines were named AES and caused some problems
4287 when not using SIM's. Affected file lib/silccrypt/rc5.c.
4289 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4291 * Added new SilcIDIP structure into the lib/silccore/id.h and
4292 replaced the old `ip' fields from all SILC ID's to that type.
4293 This is a step towards IPv6 support.
4295 The silc_id_get_len takes now the ID as an extra argument.
4296 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
4297 both IPv4 and IPv6 based ID's.
4299 The affected files are lib/silccore/id.[ch] and other files
4300 around the tree using these routines.
4302 * Removed the ID length arguments in server from various
4303 silc_server_send_notify_* routines -> they are not needed
4306 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4308 * Fixed memory leak in silc_encode_pem_file in the file
4309 lib/silcutil/silcutil.c.
4311 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4313 * Check minor version as well in the SKE. Affected files are
4314 silcd/protocol.c and lib/silcclient/protocol.c.
4316 * Added --identifier option to the server so that an identifier
4317 can be when creating the public key for the server. Affected
4318 file is silcd/silcd.c.
4320 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
4321 lib/silccrypt/silcpkcs.c.
4323 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4325 * Register default ciphers and stuff when using -C option with
4326 the server. Affected file sildc/silcd.c.
4328 * Put back the servers public key filename format, it is better
4329 than the new one. For now, the client keys are saved with the
4330 new filename format. The affected file silc/client_ops.c.
4332 * Implemented the Cipher API for the rest of the ciphers that
4333 did not implement it or implemented it the wrong way.
4335 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4337 * Register default ciphers and stuff when using the -S option
4338 in the client. Affected file silc/silc.c. Same also when
4339 creating new key pair with -C option.
4341 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4343 * Fixed the silc_verify_public_key client operation function to
4344 save the public keys differently. The fingerprint is now
4345 used as filename and not the hostname. This way also the
4346 client keys are saved uniquely and not with hostnames. The
4347 affected file is silc/client_ops.c.
4349 * Trimmed the silc_hash_fingerprint function to remove extra
4350 whitespaces from the end of the fingerprint. The affected
4351 file is lib/silccrypt/silchash.c.
4355 * Added silc_cipher_register_default function to register all
4356 default ciphers. It can be used when configuration files
4357 does not exist and the application does not want any specific
4358 ciphers in any specific order.
4360 The SilcDList is now used as silc_cipher_list dynamically
4361 allocated cipher list. Removed the static list all together
4362 and now all ciphers must be allocated to the dynamic list.
4363 The silc_cipher_alloc routine was changed to check only the
4366 All silc_cipher_* routines that used to return int returns
4369 The affected files lib/silccrypt/silccrypt.[ch].
4371 * The same thing was done to silc_hash_* as for silc_cipher_*
4372 routines. Affected files lib/silccrypt/silchash.[ch].
4374 * The same thing was done to silc_pkcs_* as for silc_cipher_*
4375 routines. Affected files lib/silccrypt/silcpkcs.[ch].
4376 Added also silc_pkcs_[un]register[_default] functions.
4377 Removed the data_context from the PKCS API.
4379 * Added silc_hmac_register_default function to register default
4380 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
4381 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
4382 to unregister all hmacs at once.
4384 * Register the default ciphers, hash functions, PKCSs and HMACs
4385 if client's configuration file does not exist. The affected
4388 * The client did not load the hash functions from the SIM
4389 modules at all. Added support for this. Affected file is
4390 silc/clientconfig.c.
4392 * When decoding public key with silc_pkcs_public_key_decode, check
4393 the supported algorithm only if PKCS are registered. Affected
4394 file lib/silccrypt/silcpkcs.c. The same was done with the
4395 silc_pkcs_private_key_decode.
4397 * Fixed the SILC List routines to keep the list always in order.
4398 It used to change the list's order when traversing the list but
4399 not it preserves the order. Affected file lib/trq/silclist.h.
4401 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4403 * Added the client library to use the SilcSocketConnection's
4404 reference counter (by silc_socket_dup) to prevent the bug that
4405 the socket object may be freed underneath async operation.
4407 * The name resolv library checking fixes in the configure.in.pre.
4410 * Created new version of the protocol drafts for future
4411 development. The -03 drafts are the ones that will be changed
4412 in the trunk now and the -02 will remain as they are.
4414 * Send list of CUMODE notifys to the router when announcing
4415 the channel users to the router. Affected file silcd/server.c.
4416 If the router receiving channel founder CUMODE for a channel
4417 that already has channel founder it will send CUMODE notify
4418 to the sender to remove the channel founder rights from the
4419 announced client. Affected file silcd/packet_receive.c.
4421 * The CUMODE notify may now use Server ID as well as the entity
4422 who changes the mode. Updated protocool specs.
4424 * Updated INSTALL and README files.
4426 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4428 * New web pages in the http://silc.pspt.fi. The pages was
4433 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4435 * Implemented the [DenyConnectin] config section in the server.
4436 Added silc_server_config_denied_conn to check whether incoming
4437 connection is denied. Affected file silcd/serverconfig.[ch].
4439 * Do not check the ports when checking the incoming configuration
4440 data if the port is 0, meaning any. Affected file is
4441 silcd/serverconfig.c.
4443 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4445 * Fixed buffer overflow in silc_string_compare in the file
4446 lib/silcutil/silcutil.c.
4448 * Fixed double free in silc_server_command_leave in the file
4451 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4453 * Fixed the version checking in the server. Affected file is
4456 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4458 * Fixed the configuration data fetching when accepting new
4459 connections in the server. Affected file silcd/server.c.
4461 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4463 * Added `sender_entry' argument to the function
4464 silc_server_packet_relay_to_channel so that we can check
4465 whether some destination actually belongs to the same route
4466 the sender belongs (ie, we must not resend the packet to the
4467 sender). Affected file silcd/packet_send.[ch].
4469 * Added `servername' field to the SilcClientEntry in the server
4470 to hold the name of the server where client is from. Affected
4471 file is silcd/idlist.h.
4473 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4475 * Moved the channel message encrypting in the router betwen
4476 router connections from silc_server_channel_message to the
4477 silc_server_packet_relay_to_channel since we want to check
4478 whether we have anybody channel before encrypting anything.
4479 Affected files silcd/packet_[receive/send].c.
4481 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4483 * Fixed the [AdminConnection] server config section to support
4484 multiple entries. Affected file silcd/serverconfig.c.
4486 * Added support into the server to check the validity of the
4487 incoming connection before executing any KE or authentication
4490 * The connection configuration is now saved to the KE and
4491 connection auth protocol contexts and not fetched anymore in
4492 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
4494 * The local hosts listenning address and port is also resolved
4495 now when starting the server. We want to have the socket object
4496 to include the real address and port for the listener. Added
4497 new function silc_net_check_local_by_sock into the files
4498 lib/silcutil/silcnet.[ch].
4500 * Fixed a broadcast bug in server -> do not broadcast if we
4503 * Fixed a routing bug. Do not route broadcast packets ever.
4504 Broadcast packets must be processed always and not routed since
4505 they may be destined to some other host than yourself and thus
4506 would get routed without no good reason. Affected file is
4509 * Added function silc_server_config_is_primary_route to check
4510 whether primary router connection has been configured (a router
4511 configuration that we are initiating). If there is not, we
4512 will assume that there is only two routers in the SILC network
4513 and we will use the incoming router connection as our primary
4514 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
4516 * Changed the order of the broadcasting. Broadcast _after_ the
4517 packet has been processed not before. Affected file is
4520 * Fixed a [ClientConnection] parsing bug. The port was never
4521 parsed correctly thus resulting to port 0. Affected file
4522 silcd/serverconfig.c.
4524 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
4525 argument and did not set the broadcast packet flag. Affected
4526 file silcd/packet_send.c. Fixed same bug in the function
4527 silc_server_send_notify as well.
4529 * If we receive NEW_ID packet for our own ID in the server, ignore
4532 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4536 * Removed the nickname from the Private Message Payload.
4537 Updated the code and the protocol specs.
4539 * Updated protocol specs for submitting to the IETF.
4541 * Tweaked the Random Number Generator a bit. Affected file
4542 lib/silccrypt/silcrng.c. Exported a new function
4543 silc_rng_[global]_add_noise which can be used to add more
4546 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4548 * Do not parse packets with different timeout when protocol
4549 is active -> may cause problem with rekey. Affected file
4552 * When server receives signoff notify it must not create
4553 new channel key if the client is on any channels since the
4554 sender of the signoff notify will create it.
4556 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4558 * Added printing of error messages during SKE protocol from the
4559 failure packet sent by server during SKE. Affected file
4562 * Removed the client's failure_callback handling with timeout
4563 and handle it immediately when received.
4565 * The SKE library returned wrong type in SUCCESS and FAILURE
4566 packets. They must be 32 bit MSB not 16 bit MSB.
4568 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4570 * Ok, rewrote the logic of the re-key and now it seems to work.
4571 I tested it on high traffic with frequent re-keys without
4572 problems. Added hmac_receive (and renamed hmac to hmac_send)
4573 in SilcClientConnection in lib/silcclient/client.h and
4574 in SilcIDListData in silcd/idlist.h. Also, removed the
4575 SilcPacketParserContext's cipher and hmac fields as they are
4576 not needed anymore and actually caused some problems when
4577 the ciphers and hmac's changed underneath the packet parser.
4579 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4581 * If re-key protocol is active then process the incoming packets
4582 synchronously since we must assure that icoming packets encrypted
4583 with the old key is processed before the new keys is set to
4584 use. This is true other packets than for REKEY packets.
4585 Affected file silcd/server.c. The same was done to client library
4586 as well, affected file lib/silcclient/client.c.
4588 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4590 * Fixed bug in client and server to accept the force send if
4591 the packet is send from silc_[server/client]_packet_process
4592 function. Otherwise the packets are never delivered, oops.
4594 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4596 * Disable force sending of packets when REKEY protocol is active.
4597 We must assure that no packet is sent directly when rekey is
4598 performed. All packets must be sent through packet queue.
4599 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
4600 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
4601 function is silc_[server/client]_packet_send_real to check
4604 * Replaced the SIM paths from example config files to
4605 /usr/local/modules. Also, make install creates now
4606 /usr/local/silc/logs directory to hold all the SILC server
4609 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4611 * Made the configure.in.pre work on Solaris. Patch by salo.
4613 * Made all ciphers compatible with non-x86 machines. Defined
4614 CBC mode macros into lib/silccrypt/ciphers_def.h.
4616 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4618 * Fixed the make install.
4620 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4622 * When MAC computation fails the silc_packet_decrypt returned 0
4623 even though it was supposed to return -1. Fixed this. The
4624 affected file is lib/silccore/silcpacket.c.
4626 * Do not replace the config files in /etc/silc (in make install)
4627 if they already exist. Affected file ./Makefile.am.
4629 * Do not send re-key packets immediately but through packet queue.
4630 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
4632 * Changed silc_net_check_host_by_sock to return FALSE if the
4633 IP/DNS could not be resolved. Though, it returns the IP address
4634 now even if it could not resolve it (but returns also FALSE).
4635 Affected file lib/silcutil/silcnet.[ch].
4637 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4639 * Added silc_pkcs_decode_identifier to decode the public key's
4640 identifier. Affected file lib/silccrypt/silpkcs.[ch].
4641 Added also silc_pkcs_free_identifier. Added also new context
4642 SilcPublicKeyIdentifier.
4644 * Added -S option to the silc client. It is used to dump the
4645 contents of the specified public key file.
4647 * Changed the PKCS api to return the public key length when
4648 setting the public key.
4650 * Fixed a fatal bug in the public and private key file loading.
4651 Affected file lib/silccrypt/silcpkcs.c.
4653 * Execute the packet parsing for client with zero (0) timeout
4654 if the protocol is active. Affected file silcd/server.c.
4656 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4658 * Made the key generation options to the silcd program. Added
4659 -C option, equivalent to client's option.
4661 * Added new [ServerKeys] config section to the server. It
4662 configures the server's public and private key.
4664 * Defined generic Public Key Payload into the protocol
4665 specification to send specific type of public keys and
4668 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
4669 public key or certificate.
4671 * Implemented the GETKEY command to the server and to the
4672 client library and on user interface.
4674 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4676 * Made preliminary `make install' work.

4693 state of the protocol. Affected file is
4694 lib/silccore/silcprotocol.[ch].
4696 * Added the re-key support with and without PFS to the client
4697 library. Re-key is performed once in an hour, by default.
4699 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
4700 Added silc_client_rekey_callback and silc_client_rekey_final.
4701 Affected files are lib/silcclient/protocol.[ch] and

4705 SilcClientConnection structure; not needed. Affected file is
4706 lib/silcclient/client.h.
4710 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4712 * Do not ask whether user wants to use the negotiated private key
4713 for private messages, just use it. Affected file is
4714 silc/local_command.c.
4716 * Added `send_enc_key' and `enc_key_len' fields to the
4717 SilcIDListData structure since they are needed in the re-key
4718 phase. Affected file is silcd/idlist.[ch].

4737 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
4738 int64 of at least the xintXX size. If void * is less that 4
4739 bytes uint32 * will be used. Defined bool as boolean.
4741 * Changed _ALL_ unsigned long and unsigned int to uint32,
4742 unsgined short to uint16 in the source tree.
4744 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
4745 not handle clients that has entry->data.registered == FALSE.
4746 They are not in the network anymore. Affected file is
4749 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

4761 * Implemented the SERVER_SIGNOFF notify handling in the client
4762 library. Affected file lib/silcclient/client_notify.c. Also,
4763 implemnted the printing of the SERVER_SIGNOFF info to the
4764 application. Affected file silc/client_ops.c.
4766 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
4767 if the deleting was successful. Affected file silcd/idlist.[ch].
4769 * Added support for public key authentication in the connection
4770 authentication protocol in the client library. Affected file
4771 lib/silcclient/protocol.c.
4773 * Changed the server's silc_idlist_get_clients_by_* interface
4774 to support already allocated array so that new entries may be
4775 added to pre-allocated array. Affected file silcd/idlist.[ch].
4776 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
4777 and command replies.
4779 * All command reply functions in the server now calls the
4780 pending command callback even if error occured. This way the
4781 error will be delivered to the client as well. Affected files
4782 silcd/command.c and silcd/command_reply.c.
4784 * Fixed INFO command to return local server's info if no server
4785 was provided. Affected file lib/silcclient/command.c.
4787 * Removed RESTART command for good. Updated the code and the
4790 * Rewrote parts of the task system. It is a bit simpler now.
4791 Removed unsued task priorities. The affected files are
4792 lib/silcutil/silctask.[ch].
4794 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4796 * Moved the USERS printing from the library to the application.
4797 Affected files lib/silcclient/command.c and silc/client_ops.c.
4799 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4803 * Added channel key re-key support. The re-key is perfomed
4804 only by the router and is done once in an hour. Added `rekey'
4805 field to the SilcChannelEntry in the server. Affected files
4806 silcd/server.c and silcd/idlist.h.
4808 * Added silc_task_unregister_by_context into the file
4809 lib/silcutil/silctask.[ch].
4811 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4813 * Added SILC_UMODE_GONE mode to indicate when the client is not
4814 present in the SILC network. Added also support to the local
4815 command AWAY that will set this mode. Added support of showing
4816 "xxx is gone" in WHOIS command. The USERS command shows the
4817 gone status as well.
4819 * Fixed setting server and router operator privileges in the
4820 server's UMODE command. Affected file silcd/command.c.
4822 * Merged the SKE KE1 and KE2 payloads into one payload. The
4823 new KE payload is equivalent to the old KE2 payload.
4825 Cleaned up the SKE Start Payload parsing. It now uses the
4826 simple buffer unformatting to do the parsing. A lot faster
4829 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
4830 to the SKE that is used to indicate whether both of the SKE
4831 parties should perform authentication. By default only the
4832 responder performs authentication. By setting this flag also
4833 the initiator must do authentication. By default it is unset
4834 since in normal SKE case, client to server connection, only
4835 the responder should do authentication. When doing SKE between
4836 two clients both should perform authentication. Updated the
4837 code and the protocol specs.
4839 * A little fix to IDENTIFY command in the server. Search the
4840 client first by hash not nickname. Affected file is
4843 * Fixed the silc_client_close_connection to support closing
4844 the client to client connections wihtout deleting too much
4845 data. Affected file lib/silcclient/client.c.
4847 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
4848 are received if protocol used to be active but is not anymore
4849 the application would crash due to NULL pointer dereference.
4850 Affected files silcd/server.c and lib/silcclient/client.c.
4852 * Added `hash' field to the SilcClientConnection to include
4853 the hash function negotiated in the SKE protocol.
4855 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
4856 to set the channel founder authentication data. A client can
4857 claim the founder rights later by providing the authentication
4858 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
4859 This way the channel founder can regain the channel founder
4860 privileges even it is left the channel. This works only on
4861 local server and the client must be connected to the same
4862 server to be able to regain the founder rights. Updated the
4863 protocol specs accordingly.
4865 Added support to the CMODE command in the client to set the
4866 founder auth data. Read the README to see how to set it.
4868 Added support to the CUMODE command to claim the founder
4869 rights. Read the README to see how to do it.
4871 Added support for the founder authentication to the Channel
4872 Entry in the server. Affected file silcd/idlist.h.
4874 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
4875 server's CMODE command. Affected file silcd/command.c.
4877 * Added the following new functions into lib/silccore/silcauth.[ch]:
4878 silc_auth_get_method and silc_auth_get_data.
4880 * The server now saves the remote hosts public key to the
4881 SilcIDListData pointer. Affected file silcd/protocol.c.
4883 * The normal server now does not remove the channel entry from
4884 the cache if the founder authentication data is set. It used
4885 to remove it if the founder was the last one on the channel on
4886 the server and left the channel. The auth data is saved and
4887 if the channel is re-joined later the old entry is used with
4888 the old auth data. Affected files silcd/command_reply.c and
4891 * Removed the `pkcs' field from the SilcIDListData structure
4892 in the server; it is not used. Affected file silcd/idlist.h.
4894 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4896 * Fixed packet processing on slow links. Partial packets were
4897 never re-processed because the incoming data buffer was cleared
4898 by the application. Application must not directly clear the
4899 sock->inbuf, the packet processing routines handle it. Fixed
4900 this in client library and in server.
4902 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4904 * Fixed the WHOIS and IDENTIFY send reply function to really
4905 check whether to send list or just one entry. Affected file
4908 * Cleaned up the LEAVE command's channel key distribution. The
4909 affected file silcd/command.c.
4911 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
4912 can enforce the channel mode as well. In that case the ID
4913 includes the ID of the server. The code now enforces the
4914 mode change if the router have different mode than the server.
4916 * The notify client operation with CMODE_CHANGE notify can now
4917 return NULL client_entry pointer if the CMODE was not changed
4918 by client. Application must check for this.
4920 * Added <Server ID> argument to INFO command to support server
4921 info fetching by Server ID.
4923 * Added silc_server_announce_get_channel_users to get assembled
4924 packets of channel users of the specified channel. Affected
4925 file silcd/server.[ch].
4927 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
4928 was freed underneath the ID Cache.
4930 * Re-announce clients when the server received CHANNEL_CHANGE
4931 notify from the router. Affected file silcd/packet_send.c.
4933 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4935 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
4936 crashed since it did not handle the fact that there is no cipher
4937 called "3" and didn't check the error condition. Now fixed.
4939 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
4940 flag. It can be used to send message requests.
4942 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4944 * Implemented the RESTART command in the client.
4946 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
4947 notice type messages. Added notice printing to the user
4950 * The channel keys are not re-generated if the channel's mode
4951 is PRIVKEY, ie private key on the channel exists. Affected
4952 files silcd/server.c and silcd/command.c.
4954 * Fixed a little bug in channel message delivery when channel
4955 private keys are set in the server. Affected file is
4956 silcd/packet_send.c.
4958 * Changed the setting on channel->on_channel = TRUE from the
4959 silc_client_save_channel_key to the JOIN command reply. The
4960 key payload is not received if the private channel key is set.
4961 Affected file lib/silcclient/command_reply.c and the
4962 lib/silcclient/client_channel.c.
4964 * When the CMODE_CHANGE notify is sent and the channel private
4965 key mode is removed the channel key must be re-generated in
4966 other cells as well. Added this support for the router in the
4967 silcd/packet_receive.c.
4969 * Added new local command NOTICE to send notice message on
4970 channel. Affected file silc/local_command.[ch].
4972 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4974 * Added new local command ME to the client. It is used to send
4975 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
4976 some action. Affected file silc/local_command.[ch].
4978 * Changed channel_message and private_message client operations
4979 to deliver the message flags to the application. Added also
4980 the `flags' arguments to the silc_client_send_channel_message
4981 and silc_client_send_private_message functions. Affected file
4984 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
4986 * Redefined the Private Message Payload to support private message
4987 keys and to support the new private message flags. Updated
4988 the protocol specs. Flags makes it possible to have for example
4989 CTCP style messages.
4991 * Added new type SilcPrivateMessagePayload and defined an API
4992 for it in the lib/silcclient/silcprivate.[ch].
4994 * Tested private message private keys successfully. Tested the
4995 private message key set, unset and list commands with the new
4998 * Redefined the Channel Message Payload to include the channel
4999 message flags (equal with private message flags) to support
5000 for example CTCP style messages.
5002 * Defined some of the message (for channel and private message)
5003 flags. Updated the protocol specs and added the flags to the
5004 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
5006 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5008 * Added SilcKeyAgreementStatus type to the key agreement routines
5009 to indicate the current status and error if one occured.
5010 The status types are defined in the lib/silcclient/silcapi.h.
5012 * Added new local command KEY that is used to set and unset private
5013 keys for channels, set and unset private keys for private messages
5014 with remote clients and to send key agreement requests and
5015 negotiate the key agreement protocol with remote client. The
5016 key agreement is supported only to negotiate private message keys,
5017 it currently cannot be used to negotiate private keys for channels,
5018 as it is not convenient for that purpose.
5020 * Fixed a minor pending callback setting bug in the function
5021 silc_client_get_client_by_id_resolve, now the function works.
5022 Affected file lib/silcclient/idlist.c.
5024 * Added function silc_net_get_local_port to get local bound
5025 port by socket. Added to lib/silcutil/silcnet.[ch].
5027 * Added `sockets' and `sockets_count' fields to the SilcClient
5028 object. They hold the sockets of the listenning sockets in
5029 the client. Listenning sockets may be for example the key
5030 agreement server. Affected file lib/silcclient/client.[ch].
5031 Added functions the silc_client_add_socket and the
5032 silc_client_del_socket. They are exported to the application
5035 * Added ~./silc/clientkeys to support other client's public keys.
5037 * Renamed verify_server_key client operation to verify_public_key
5038 and added one argument to indicate the type of the connection
5039 (server, client etc.).
5041 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5043 * Added silc_server_connection_auth_request to handle the
5044 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
5045 silcd/packet_receive.[ch].
5047 * Added silc_server_send_connection_auth_request into the
5048 silcd/packet_send.c to send the connection auth request packet.
5050 * Cleaned up the silcd/protocol.c a bit and fixed some memory
5053 * Fixed the public key authentication in responder side in the
5054 server. The `auth_data' pointer includes the SilcPublicKey
5055 not the path to the public key. Affected file silcd/protocol.c.
5057 * Implemented the public key authentication in the initiator side
5058 in the server. Affected file silcd/protocol.c.
5060 * Removed the [RedirectClient] config section from the server
5061 configuration. Is not needed and I don't want to implement it.
5063 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5065 * Cleaned up the CMODE command in the server. It now works
5066 correctly and supports all the modes defined in the protocol.
5067 Affected file is silcd/command.c.
5069 * Added `hmac_name' field to the SilcChannelEntry in the server
5070 to hold the default HMAC of the channel. It can be set when
5071 creating the channel (with JOIN command). Affected files
5074 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
5075 type to indicate the change of the current cipher and hmac
5076 on the channel. Client can safely ignore the <cipher> argument
5077 (if it chooses to do so) since the CHANNEL_KEY packet will
5078 force the channel key change anyway. The <hmac> argument is
5079 important since the client is responsible of setting the new
5080 HMAC and the hmac key into use.
5082 * Fixed the CMODE command in the client library as well.
5084 * Tested CMODE command in router environment successfully.
5086 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5088 * Show the version of the remote client (or server) when connecting
5089 to the server. It is logged to the log file. Affected file
5090 is silcd/protocol.c.
5092 * Fixed the KILLED notify handling in the client library. The
5093 client must be removed from all channels when receiving the
5096 Also, do not remove the client entry when giving the KILL
5097 command but when the KILLED notify is received.
5099 * Removed silc_idlist_find_client_by_nickname from the server.
5100 Not needed anymore. Affected files silcd/idlist.[ch].
5102 * Implemented the CHANNEL_CHANGE notify type handling to the
5103 server. Affected file silcd/server.c.
5107 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5109 * Added silc_server_send_notify_invite to send the INVITE
5110 notify between routers.
5112 * Implemented the INVITE command correctly to the server.
5114 * Implemented the INVITE notify type handling in the server.
5116 * Implemented the INVITE command to the client library and on the
5119 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5121 * Added function silc_server_get_client_resolve to find the
5122 client entry by ID from all ID lists and then resolve it
5123 (using WHOIS) if it cannot be found. Affected file is
5126 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5128 * Implemented the BAN command to the client library.
5130 * The JOIN command in the server now checks the invite list
5133 * Changed the silc_command_reply_payload_encode_va and the
5134 silc_command_payload_encode_va to support that if argument is
5135 NULL it ignores and checks the next argument. Affected file
5136 lib/silccore/silccommand.c.
5138 * Added silc_server_send_notify_ban to send the BAN notify
5139 type between routers.
5141 * Chaned the silc_notify_payload_encode to support that if
5142 argument is NULL it ignores and checks the next argument.
5143 Affected file lib/silccore/silcnotify.c.
5145 * Tested ban lists in router environment successfully.
5147 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5149 * Implemented BAN command to the server, in silcd/command.[ch].
5151 * Removed the BAN and INVITE_LIST modes from the CMODE command
5154 * Added function silc_string_match to regex match two strings.
5155 Affected files lib/silcutil/silcutil.[ch].
5157 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5159 * Redefined parts of the SilcChannelEntry in the server to support
5160 the new ban and invite lists.
5162 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5164 * Redefined the INVITE command. The same command can be used to
5165 invite individuals to the channel but also to manage the invite
5166 list of the channel (to add to and remove from the invite list).
5167 Updated the protocol specs.
5169 * Added new command SILC_COMMAND_BAN that can be used to manage
5170 the ban list of the channel. Updated the protocol specs.
5172 * Removed the channel modes: the SILC_CMODE_BAN and the
5173 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
5174 in the CMODE command. The equivalent features are now available
5175 using INVITE and BAN commands. Updated the protocol specs.
5177 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
5178 in the network about change in the current ban list. The notify
5179 type is not used by the client.
5181 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
5182 support the invite lists.
5184 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5186 * Added new function silc_string_regexify that converts string
5187 including wildcard characters into regex string that can
5188 be used by the GNU regex library. Added into the file
5189 lib/silcutil/silcutil.[ch].
5191 Added silc_string_regex_combine to combine to regex strings
5192 into one so that they can be used as one regex string by
5193 the GNU regex library. Added into the file
5194 lib/silcutil/silcutil.[ch].
5196 Added silc_string_regex_match to match two strings. It returns
5197 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
5199 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5201 * Imported GNU regex to the soruce tree into lib/contrib.
5202 Fixed some compiler warning from the regex.c.
5204 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5206 * Fixed MOTD command in the server to work in router environment.
5208 * Fixed the MOTD command in the client library to support
5209 the server argument in the command.
5211 * Added `nickname_len' argument to the silc_idlist_add_client
5212 in the server, as the `nickname' argument may be binary data
5215 * Added silc_idlist_get_channels to return all channels from
5218 * Implemented LIST command to the server. Affected file is
5221 * Implemented the LIST command to the client library and on the
5224 * Added [<user count>] argument to the LIST command reply.
5225 With private channels the user count is not shown.
5227 * Updated TODO and README.
5229 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5231 * The client entry's data.registered must be TRUE even with
5232 global client entry on global client list. The data.registered
5233 is used to check whether the client is anymore in the network,
5234 for example with WHOWAS command so it must be valid.
5236 * Fixed the WHOWAS command in the server. It now actually works
5237 in router environment. Added function into silcd/command_reply.c
5238 silc_server_command_reply_whowas_save.
5240 * Added silc_idlist_purge function to the silcd/idlist.c
5241 to periodically purge the ID Cache.
5243 * Fixed INFO command in the server. It works now in router
5244 environment. Added <server name> argument to the INFO command
5245 reply. Updated the protocol specs.
5247 * Fixed minor bug in silc_idcache_purge to not purge if the
5248 expire value is zero.
5250 * Fixed various bugs in WHOIS and IDENTIFY command handling as
5251 they were buggy because of the WHOWAS information.
5253 * Fixed local command MSG to handle the async resolving of
5254 the remote client properly. It used to fail the first MSG.
5255 Affected file silc/local_command.c.
5257 * Added `data_len' field to SilcIDCache context.
5259 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5261 * Update TODO. Todo in commands in the server.
5263 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5265 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
5266 used by routers as broadcast packet to inform other routers
5267 about the changed user mode.
5269 Implemented the notify handling in the server. Affected file is
5270 silcd/packet_receive.c. Added the function
5271 silc_server_send_notify_umode to the silcd/packet_send.[ch].
5273 * Added new generic Channel Payload and deprecated the New Channel
5274 Payload. The New Channel Payload is now the generic Channel
5277 * Added new argument `mode' to the silc_server_send_new_channel
5278 as it is required in the Channel Payload now.
5280 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
5281 and created a new and real SilChannelPayload to represent the
5282 new generic Channel Payload. Implemented the encode/decode
5283 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
5285 * Added silc_server_get_client_channel_list to return the list
5286 of channels the client has joined for WHOIS command reply.
5287 Affected file silcd/server.[ch].
5289 * Implemented the channel list sending in the WHOIS command reply
5290 in server and in the client.
5292 Implemented the channel list displaying on the user interface
5293 as well. Affected file silc/client_ops.c.
5295 * Added silc_channel_payload_parse_list to parse list of Channel
5296 Payloads. It returns SilcDList list of SilcChannelPayloads.
5297 Client for example can use this function to parse the list of
5298 channels it receives in the WHOIS command reply. The caller
5299 must free the list by calling silc_channel_payload_list_free.
5300 Affected files lib/silccore/silcchannel.[ch].
5302 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5304 * Added one new argument <user mode> to the WHOIS command reply
5305 to return the mode of the user in SILC. Updated the protocol
5308 Implemented it to the server and client.
5310 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5312 * Fixed the mode printing on the user interface on joining.
5313 Affected file silc/client_ops.c.
5315 * Implemented the UMODE command and user modes in general to the
5316 client library and to the user interface.
5318 * Implemented the UMODE command to the server.
5320 * The server now sends UNKNOWN_COMMAND error status if client sends
5321 unknown command. Affected file silcd/command.c.
5323 * All server commands now handle the command identifier the right
5324 way when sending the command reply to the client. The client can
5325 use to identify the command replies with the identifier.
5327 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5329 * Added silc_server_get_client_route to resolve the route to
5330 the client indicated by the client ID. Affected file is
5333 * Added silc_server_relay_packet as general function to relay
5334 packet to arbitrary destination. This deprecates functions
5335 like _send_private_message_key, _relay_notify etc. Affected
5336 file is silcd/packet_send.[ch].
5338 Removed silc_server_send_key_agreement,
5339 silc_server_send_private_message_key and
5340 silc_server_packet_relay_notify functions from the file
5341 silcd/packet_send.[ch].
5345 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
5346 server. Affected file silcd/packet_receive.[ch].
5348 * Implemented the KILL command to the client. Implemented the
5349 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
5350 Affected files lib/silcclient/command[_reply].c and
5351 lib/silcclient/client_notify.c. Implemented the KILL notify
5352 printing in the user inteface.
5354 * Fixed a lot silc_parse_nick memory leaks from the client
5355 library in the file lib/silcclient/command.c.
5357 * Changed the silc_server_send_notify_on_channels's `sender'
5358 argument from SilcSocketConnection to SilcClientEntry to
5359 check the sender as entry and not as connection object and not
5360 to send to the client provided as argument. The affected file
5361 is silcd/packet_send.[ch].
5363 * The notify packets that are destined directly to the client used
5364 to not to be processed by the server. Now changed that and the
5365 server processes all notify packets. After relaying the packet
5366 to the client the notify packet is processed in the server.
5368 * The silc_server_free_client_data now checks whether there is
5369 pending outgoing traffic for the client and purges the data to
5370 the network before removing the client entry.
5372 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5374 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
5375 an client is killed from the SILC Network. Updated the protocol
5378 Added new function silc_server_send_notify_killed to the
5379 silcd/packet_send.[ch].
5381 * Added function silc_server_packet_relay_notify to relay notify
5382 packets that are destined directly to a client. In this case
5383 the server does not process the notify packets but merely relays
5384 it to the client. Affected file silcd/packet_send.[ch].
5386 Added also silc_server_packet_process_relay_notify to check
5387 whereto relay the notify. Affected file is
5388 silcd/packet_receive.[ch].
5390 * Implemented the KILL command to the server.
5394 * Added the backup schema desgined last fall to the protocol
5395 specs for everyone to see. The specification is in the
5396 *-spec-xx.txt draft and the packet type definitions for the
5397 backup routers is in *-pp-xx.txt draft. Thusly, added also
5398 new packet type SILC_PACKET_CELL_ROUTERS.
5400 * A big security problem in the implementation discovered. The
5401 signoff of an client did not cause new channel key generation
5402 which it of course should've done. The channel keys must be
5403 always re-generated when client leaves (or signoffs) the channel.
5404 The silc_server_remove_from_channels funtion now handles
5405 the channel key re-generation.
5407 * Added `sender' argument to the silc_server_send_notify_on_channels
5408 to not to send the client provided as argument. Affected file
5409 silcd/packet_send.[ch].
5411 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5413 * Implemented OPER and SILCOPER commands into the server and
5416 * Added silc_auth_verify and silc_auth_verify_data to verify
5417 the authentication directly from the authentication payload.
5418 It supports verifying both passphrase and public key based
5419 authentication. Affected file lib/silccore/silcauth.[ch].
5421 * Added `hash' field to the SilcIDListData structure. It is the
5422 hash negotiated in the SKE protocol. Affected file is
5425 * Slight redesigning of the SilcAuthPayload handling routines.
5426 Do not send SilcPKCS but SilcPublicKey as argument.
5428 * Implemented the public key authentication support to the
5429 serverconfig. The public key is loaded from the provided path
5430 and saved as authentication data to void * pointer. Thus,
5431 changed the unsigned char *auth_data to void *auth_data;
5433 * Fixed SHUTDOWN command to send the reply before the server
5434 is shutdown. :) Affected file silcd/command.c.
5436 * Fixed fatal bug in CONNECT command. The hostname was invalid
5437 memory and server crashed. Affected file silcd/command.c.
5439 * Fixed fatal bug in CLOSE command. The server_entry became
5440 invalid but was referenced later in the command. Affected file
5443 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5445 * Fixed fatal bug in failure packet handling. Server ignored
5446 the failure and thus crashed when it came.
5450 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5452 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
5453 that the command may be executed only once in (about) 2 seconds.
5454 The old SILC_CF_LAG flag is same but allows command bursts up
5455 to five before limiting.
5457 Added the support for CF_LAG and CF_LAG_STRICT flags to the
5458 server code. Various commands now includes the CF_LAG_STRICT
5459 flag to disallow any kind of miss-use of the command.
5461 * Fixed the silc_buffer_unformat to not to allocate any data
5462 if the length of the data is zero. It used to allocate the
5463 length + 1. Affected file lib/silcutil/silcbuffmt.c.
5465 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5467 * Changed the format of AdminConnection configuration section
5468 in the server. Added username of the admin to the format.
5469 Affected files silcd/serverconfig.[ch].
5471 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
5472 to return admin configuration data by host, username and/or
5475 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5477 * Implemented WHOWAS command to the server. Added the functions:
5479 silc_server_command_whowas_parse,
5480 silc_server_command_whowas_send_reply,
5481 silc_server_command_whowas_from_client and
5482 silc_server_command_whowas_from_server
5484 * Added <Client ID> argument to the WHOWAS command reply. Updated
5485 the protocol specs accordingly.
5487 * Implemented WHOWAS command and command_reply to the client
5490 Implemented the WHOWAS printing on the user interface.
5492 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5494 * Added new argument to the WHOWAS command reply, the real name.
5495 It is an optional argument. Updated the protocol specs.
5497 * Added SilcIDCacheDestructor callback that is registered when
5498 the SilcIDCache is allocated. The callback is called when
5499 an cache entry in the ID Cache expires, or is purged from the
5500 cache. Added into lib/silccore/idcache.[ch].
5502 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
5503 to destruct the client entries when the cache entry expires.
5504 Other ID Cache's in server and in the client library ignores
5507 * If the ID Cache entry's `expire' field is zero then the entry
5508 never expires. Added boolean `expire' argument to the
5509 silc_idcache_add function in the lib/silccore/idcache.[ch].
5510 If it is TRUE the default expiry value is used.
5512 * Added silc_server_free_client_data_timeout that is registered
5513 when client disconnects. By default for 5 minutes we preserve
5514 the client entry for history - for WHOWAS command.
5516 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5518 * Added support to the server to enforce that commands are not
5519 executed more than once in 2 seconds. If server receives
5520 commands from client more frequently, timeout is registered
5521 to process the commands. Affected file silcd/command.c.
5522 Added new function silc_server_command_process_timeout.
5524 * Changed NICK_NOTIFY handling in client library to check that
5525 if the client's nickname was changed, so there is no need to
5526 resolve anything from the server.
5528 * Removed error printing from the WHOIS and IDENTIFY commands.
5529 If error occurs then it is ignored silently in the client library.
5530 The application, however, may map the received error to
5531 human readable error string. The application currently maps
5532 the NO_SUCH_NICKNAME error to string.
5534 * Made the command status message public to the application. Moved
5535 them from lib/silcclient/command_reply.c to
5536 lib/silcclient/command_reply.h. The application can map the
5537 received command status to the string with the
5538 silc_client_command_status_message function.
5540 * Added check to the server to check that client's ID is same
5541 as the Source ID in the packet the client sent. They must
5544 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5546 * Added dist-bzip hook to the Makefile.am to make bzip2
5547 compressed distributions.
5549 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5551 * Server now enforces the maximum length for the nickname and
5552 the channel as protocol specification dictates. 128 bytes for
5553 nickname and 256 bytes for channel name.
5555 * Moved the WHOIS printing to the application. The client libary
5556 does not print out the WHOIS information anymore, the application
5557 must do it. Renamed silc_client_command_reply_whois_print to
5558 the silc_client_command_reply_whois_save.
5560 The client's idle time is also sent to the application now, and
5561 the idle is shown on screen.
5563 * Added silc_client_command_reply_identify_save to save the
5564 received IDENTIFY entries.
5566 * Do not check for channel private keys in message sending and
5567 reception if the channel does not have the PRIVKEY mode set.
5568 Affected file lib/silclient/client_channel.c.
5570 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5572 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
5573 just surfaced after chaning the JOIN procedure.
5575 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5577 * Added silc_client_get_clients_by_list to get client entries
5578 from Client ID list, that is returned for example by JOIN
5579 and USERS command replies. The application should use this
5580 function for example when JOIN command reply is received to
5581 resolve the clients already on the channel (library does not
5582 do that anymore as USERS command reply is not used in the JOIN
5583 procedure anymore). Affected files lib/silcclient/silcapi.h and
5584 lib/silcclient/idlist.c.
5586 * JOIN command reply and USERS command reply returns now SilcBuffer
5587 pointers instead of unsigned char pointers when returning
5588 the client list and mode list.
5590 * Added <Client ID> argument to the JOIN command reply, mainly
5591 for the server to identify for which client the command was
5592 originally sent. Updated protocol specs accordingly.
5594 * Added SilcDlist private_key pointer to the SilcChannelEntry
5595 in the client to support the channel private keys. Affected
5596 file is lib/silcclient/idlist.h.
5598 * Added SilcChannelPrivateKey argument to the function
5599 silc_client_send_channel_message so that application can choose
5600 to use specific private ke if it wants to. If it is not provided,
5601 the normal channel key is used, unless private keys are set.
5602 In this case the first (key that was added first) is used
5603 as the encryption key.
5605 * Implemented the support for channel private key handling.
5606 Implemented the following functions:
5608 silc_client_add_channel_private_key,
5609 silc_client_del_channel_private_keys,
5610 silc_client_del_channel_private_key,
5611 silc_client_list_channel_private_keys and
5612 silc_client_free_channel_private_keys
5614 Affected file lib/silcclient/client_channel.c.
5616 * Added the support for the private keys in the channel message
5617 sending and encryption and in the message reception and
5618 decryption. Affected funtions are
5619 silc_client_send_channel_message and silc_client_channel_message.
5621 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5623 * Added SKE's key verify callback to the client library's
5624 KE protocol context. Affected files lib/silcclient/protocol.[ch].
5626 * Removed the statement that server (or router) must send USERS
5627 command reply when joining to the channel so that the client
5628 knows who are on the channel. Instead, the client list and
5629 client's mode list is now sent in the JOIN command reply to the
5630 client who joined channel. This is better solution.
5632 * Added function silc_server_get_users_on_channel and function
5633 silc_server_save_users_on_channel to the silcd/server.[ch].
5635 * Removed function silc_server_command_send_users from the
5638 * Do not show topic on the client library anymore. The topic is
5639 sent in the command reply notify to the application and the
5640 application must show the topic now.
5642 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5644 * Added client searching by nickname hash into the IDENTIFY and
5645 WHOIS commands in the server as they were clearly missing from
5646 them. Affected file is silcd/command.c.
5648 * Fixed a bug in private message receiving in the client library.
5649 The remote ID was freed and it wasn't supposed, now it is
5652 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5654 * Minor fix to the channel payload; allocate the data area, as it
5655 needs to be of specific length.
5657 * If the key agreement port is zero then the operating
5658 system will define the bound port. Affected files are
5659 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
5661 * Added new function silc_channel_payload_decrypt into the file
5662 lib/silccore/silcchannel.[ch].
5664 * Moved the channel message etc, check from silc_packet_decrypt
5665 to applications. The library calls now a generic
5666 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
5667 when the packet is either normal or special. This was done to
5668 allow more wide range of checking that was not allowed when
5669 the code was in library. Now applications can do virtually any
5670 checks to the packet and return to the library the decision how
5671 the packet should be processed. Affected files are
5672 lib/silccore/silcpacket.[ch].
5674 Added silc_server_packet_decrypt_check to the server and
5675 silc_client_packet_decrypt_check to the client library.
5677 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
5678 to send with specified source and destination information.
5680 * Channel message delivery between routers was broken after the
5681 channel key distribution was fixed earlier. The channel key
5682 was used be to distributed to other routers as well which is not
5683 allowed by the protocol. Now this is fixed and channel keys
5684 really are cell specific and the channel message delivery between
5685 routers comply with the protocol specification.
5687 * Fixed various commands in server to check also the global list
5688 for the channel entry and not just the local list. The affected
5689 file silcd/command.c.
5691 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5693 * Added assert()s to buffer formatting and unformatting routines
5694 to assert (if --enable-debug) when error occurs. Affected
5695 file: lib/silcutil/silcbuffmt.c.
5697 * Changed to auto-reconnect to check whether the remote host is
5698 router and register the re-connect timeout if it is. It used
5699 to check that whether we are normal server, but router must do
5700 auto-reconnect with another router as well. Affected file
5703 * Removed the [<key len>] option from CMODE command as the cipher
5704 name decides the key length, nowadays. See the defined ciphers
5705 from the protocol specification.
5707 * Added [<hmac>] option to the CMODE command to define the HMAC
5708 for the channel. Added SILC_CMODE_HMAC channel mode.
5710 * Added [<hmac>] option for the JOIN command so that user can
5711 select which HMAC is used to compute the MACs of the channel
5714 * Added Hmac field to the Channel Message Payload. The integrity
5715 of plaintext channel messages are now protected by computing
5716 MAC of the message and attaching the MAC to the payload. The
5717 MAC is encrypted. Now, it is clear that this causes some
5718 overhead to the size of the packet but rationale for this is that
5719 now the receiver can verify whether the channel message decrypted
5720 correctly and also when private keys are set for the channel the
5721 receiver can decrypt the packet with several keys and check from
5722 the MAC which key decrypted the message correctly.
5724 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
5725 lib/silccrypt/silccipher.[ch].
5727 * Added silc_hash_len to return the digest length into the
5728 lib/silcrypt/silchash.[ch].
5730 * Rewrote parts of Silc Channel Payload interface in the
5731 lib/silccore/silcchannel.[ch]. The encode function now also
5732 encrypts the packet and parse function decrypts it.
5734 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5736 * Fixed a minor formatting bug in the SKE's key material processing.
5737 It actually might have processed the keys wrong way resulting
5740 * Redefined the mandatory HMAC algorithms and added new algorithms.
5741 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
5742 and hmac-md5 truncated to 96 bits. The mandatory is now
5743 hmac-sha1-96. Rest are optional (including the one that used
5744 to be mandatory). Rationale for this is that the truncated HMAC
5745 length is sufficient from security point of view and can actually
5746 make the attack against the HMAC harder. Also, the truncated
5747 HMAC causes less overhead to the packets. See the RFC2104 for
5750 * Added new [hmac] configuration section. The SKE used to use
5751 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
5752 is of course wrong. The official names that must be proposed in
5753 the SKE are the ones defined in the protocol specification
5754 (hmac-sha1-96 for example). The user can configure any hmac
5755 using any hash function configured in the [hash] section. At
5756 least, the mandatory must be configured.
5758 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
5760 * Added HMAC list to the SKE proposal list. It has now both
5761 hash algorithm list and HMAC list. This makes the protocol
5762 incompatible with previous versions. The SKE now seems to work
5763 the way it is supposed to work, for the first time actually.
5765 * Defined plain Hash algorithms to the protocol specification.
5768 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5770 * Implemented support for key agreement packets into the server.
5771 Added functions silc_server_key_agreement and
5772 silc_server_send_key_agreement. Other than these functions,
5773 server has nothing to do with this packet.
5775 * Added support for private message key packets into the server.
5776 Added functions silc_server_private_message_key and
5777 silc_server_send_private_message_key.
5781 * Changed the silc_[client|server]_protocol_ke_set_keys to be
5782 called in the protocol's final callback instead in the END
5783 protocol state. This makes a little more sense and in the same
5784 time in client we can use the same protocol routines for normal
5785 key exchange and to key agreement packet handling as well.
5787 * Added to both client's and server's KE protocol context the
5788 SilcSKEKeyMaterial pointer to save the key material. We will
5789 bring the key material to the protocol's final callback by doing
5790 this. The final callback must free the key material.
5792 * Added SKE's packet_send callback into client's KE protocol
5793 context so that the caller can choose what packet sending function
5794 is used. This way we can use different packet sending when
5795 doing normal SKE when doing key agreement packet handling (in
5796 the key agreement packet handling we do not want to encrypt
5799 * Implemented the responder side of the key agreement routines
5800 in the client. The client can now bind to specified port and
5801 accept incoming key negotiation. The key material is passed
5802 to the application after the protocol is over.
5804 * Implemented the processing of incoming Key Agreement packet
5805 in the client. Added function silc_client_key_agreement to
5808 * Implemented the intiator side of the key agreement routines
5809 in the client. The client can now initiate key agreement with
5810 another remote client. The key material is passed to the
5811 application after the protocol is over.
5813 * Created client_keyagr.c to include all the key agreement
5816 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
5817 SILC_TASK_CALLBACK except that it is not static.
5819 * Created client_notify.c and moved the Notify packet handling
5820 from the client.[ch] into that file.
5822 * Created client_prvmsg.c and moved all private message and
5823 private message key routines from the client.[ch] into that file.
5825 * Create client_channel.c and moved all channel message and
5826 channel private key routines from the client.[ch] into that file.
5828 * Changed silc_client_get_client_by_id_resolve to resolve with
5829 WHOIS command instead of IDENTIFY command, in the file
5830 lib/silclient/idlist.c.
5832 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5834 * Implemented the SKE's responder side to the Client library.
5836 * When FAILURE is received to the protocol do not trust it
5837 blindly. Register a timeout to wait whether the remote closes
5838 the connection as it should do it, only after that process the
5839 actual failure. This was changed to both client and server.
5841 * Added client_internal.h to include some of the structures
5842 there instead of client.h in lib/silcclient/.
5844 * Added function silc_task_unregister_by_callback to unregister
5845 timeouts by the callback function.
5847 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5849 * Some "Incomplete WHOIS info" errors has been appearing on the
5850 log files. Took away the entry->userinfo check from WHOIS
5851 reply sending. The entry->userinfo is now " " if client did not
5852 provide one. I thought this was fixed earlier but something
5853 is wrong still. Let's see if the error still appears.
5855 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5857 * Fixed a minor bug in the login when the channel key is
5858 re-generated in the server. It used to generate the key in
5859 wrong order and thus caused problems in the channel traffic.
5861 * Fixed a minor bug in channel key distsribution after
5862 KICK command. The key was not sent to the router even though
5865 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5867 * Added silc_ske_process_key_material_data as generic routine
5868 to process any key material as the SILC protocol dictates. The
5869 function is used by the actual SKE library but can be used by
5870 applications as well. This relates to the private message keys
5871 and the channel private keys since they must be processed the
5872 same way the normal SILC session keys. The protocol dictates
5873 this. Affected files: lib/silcske/silcske.[ch].
5875 Added also silc_ske_free_key_material to free the
5876 SilcSKEKeyMaterial structure.
5878 * Defined silc_cipher_set_key function to set the key for
5879 cipher without using the object's method function. The affected
5880 files: lib/silccrypt/silccipher.[ch].
5882 * Implemented silc silc_client_add_private_message_key,
5883 silc_client_add_private_message_key_ske,
5884 silc_client_del_private_message_key,
5885 silc_client_list_private_message_keys and
5886 silc_client_free_private_message_keys functions in the
5889 Added functions silc_client_send_private_message_key to send
5890 the Private Message Key payload and silc_client_private_message_key
5891 to handle incoming Private Message Key payload.
5893 * Added Cipher field to the Private Message Key payload to set
5894 the cipher to be used. If ignored, the default cipher defined
5895 in the SILC protocol (aes-256-cbc) is used.
5897 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5899 * Removed lib/silcclient/ops.h file.
5901 Redefined parts of the SILC Client Library API. Created new
5902 file silcapi.h that deprecates the ops.h file and defines the
5903 published Client Library API. Defined also private message key
5904 API and channel private key API into the file.
5906 This is the file that the application must include from the
5907 SILC Client Library. Other files need not be included by
5908 the application anymore.
5910 * Added new key_agreement client operation callback and also
5911 defined the Key Agreement library API for the application.
5913 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5915 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
5916 is used by clients to request key negotiation between another
5917 client in the SILC network. If the negotiation is started it
5918 is performed using the SKE protocol. The result of the
5919 negotiation, the secret key material, can be used for example
5920 as private message key.
5922 Implemented the Key Agreement payload into the files
5923 lib/silccore/silauth.[ch].
5925 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5927 * Redefined ciphers for the SILC protocol. Added some new ciphers
5928 and defined the key lengths for the algorithms. Changed the
5929 code accordingly. The default key length is now 256 bits.
5931 * Fixed SKE key distribution function silc_ske_process_key_material
5932 when the key length is more than 128 bits. The default key
5933 length in SILC is now 256 bits.
5935 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
5936 to indicate unsupported algorithm.
5938 * Renamed rijndael.c to aes.c and all functions as well.
5940 * Fixed a long standing channel key setting bug in client library.
5941 Weird that it has never surfaced before.
5943 * Fixed bug in channel deletion. If the entire channel is removed
5944 then it must also delete the references of the channel entry
5945 from the client's channel list as the client's channel entry and
5946 the channel's client entry share same memory.
5948 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5950 * Implemented CONNECT and SHUTDOWN commands in the client.
5952 * Implemented CLOSE command to the client.
5954 * Added the function silc_idlist_find_server_by_name into the
5955 files silcd/idlist.[ch].
5957 Added the function silc_idlist_find_server_by_conn into the
5958 files silcd/idlist.[ch].
5960 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5962 * DIE command was renamed to SHUTDOWN. Updated the both code
5965 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
5966 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
5968 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
5971 * Added function silc_server_create_connection function to create
5972 connection to remote router. My server implementation actually
5973 does not allow router to connect to normal server (it expects
5974 that normal server always initiates the connection to the router)
5975 so the CONNECT command is only good for connecting to another
5978 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
5980 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
5981 or some other client was kicked from the channel.
5983 Implemented the handling of the notify type to both client
5986 Implemented silc_server_send_notify_kicked to send the KICKED
5987 notify. It is used to send it to the server's primary router.
5989 * Implemented the KICK command into server and client.
5991 * Added `query' argument to the silc_idlist_get_client function
5992 to indicate whether to query the client from server or not if
5995 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
5996 to indicate that the client is not channel founder.
6000 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6002 * Removed the rng context from SilcPacketContext structure and
6003 changed that the packet routine uses the Global RNG API.
6005 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6007 * Added support for quit message that client can "leave" on the
6008 channel when it quits the SILC. It is ditributed inside the
6009 SILC_NOTIFY_TYPE_SIGNOFF notify type.
6011 Added silc_server_free_client_data that will take the
6012 signoff message as argument.
6014 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
6016 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6018 * Updated parts of the protocol specification to keep it up
6021 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6023 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
6024 payloads in one packet.
6026 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
6027 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
6028 use now the new List flag.
6030 * Also deprecated the following packet types: REPLACE_ID,
6031 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
6033 * Added list support for Notify packet in server.
6035 * Added silc_server_send_notify_channel_change to send the
6036 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
6037 the silc_server_send_replace_id.
6039 * Added silc_server_send_notify_nick_change to send the
6040 NICK_CHANGE notify type. Deprecates the function
6041 silc_server_send_replace_id.
6043 * Added silc_server_send_notify_join to send the JOIN notify type.
6044 Deprecates the function silc_server_send_new_channel_user.
6046 * Added silc_server_send_notify_leave to send LEAVE notify type.
6047 Deprecates the function silc_server_send_remove_channel_user.
6049 * Added silc_server_send_notify_cmode and
6050 silc_server_send_notify_cumode to send CMODE and CUMODE notify
6051 types. Deprecates the silc_server_send_set_mode function.
6053 * Added SERVER_SIGNOFF notify type to indicate that server has
6054 quit. This means that all clients on the channel from that
6055 server will drop. This can be also used when netsplit happens.
6057 Deprecated REMOVE_ID packet type since it is not needed anymore
6060 Added silc_server_send_notify_server_signoff to send the
6061 SERVER_SIGNOFF notify type. Deprecates the function
6062 silc_server_send_remove_id.
6064 Added also silc_server_send_notify_signoff to send the
6065 SIGNOFF notify type.
6067 * Employed the PKCS #1. It is the mandatory way to do RSA in the
6068 SILC protocol from this day on. Changed the protocol
6069 specification as well.
6071 * Added silc_server_send_notify_topic_set to send TOPIC_SET
6072 notify type. It is used between routers to notify about
6073 topic changes on a channel.
6075 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
6078 * Partly updated the protocol specification to comply with the
6079 changes now made. It is still though a bit outdated.
6081 * The JOIN notify type now takes one extra argument <Channel ID>.
6082 The packet used to be destined to the channel but now the
6083 JOIN type may be sent as list thus it is impossible to
6084 destine it to any specific channel. By adding this argument
6085 it is again possible.
6087 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6089 * Added CREDITS file. The CHANGES and CREDITS file will appear
6090 in the distribution as well.
6092 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6094 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
6095 types in the server's silcd/packet_receive.c.
6097 * Implemented CMODE and CUMODE to work in router environment.
6099 * Fixed minor encoding and decoding buglet from the
6100 lib/silccore/silcmode.c.
6102 * Fixed buffer overflow from lib/silcclient/command.c in USERS
6105 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
6107 * Changed all SilcConfigServer* and silc_config_server* to
6108 SilcServerConfig* and silc_server_config*, respectively.
6111 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6113 * Associated the ID (client or server ID) to the Authentication
6114 Payload to avoid any possibility of forging. Updated the
6115 protocol specification and the code accordingly.
6117 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6119 * The RSA key length is now save to the RsaKey context in the
6120 key generation process in lib/silccrypt/rsa.c. The key length
6121 is now used to figure out the maximum size of the block allowed
6122 to be encrypted/signed.
6124 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
6125 is equivalent to the silc_mp_mp2bin but does not allocate any
6128 * Changed silc_mp_mp2bin API to take length argument. If it is
6129 non-zero then the buffer is allocated that large. If zero, then
6130 the size is approximated using silc_mp_sizeinbase, which however
6133 * Created Global RNG API which is global RNG that application can
6134 initialize. After initializing, any routine anywhere in the
6135 code (including library) can use RNG without allocating a new
6136 RNG object. This was done to allow this sort of use of the
6137 RNG in code that has no chance to allocate RNG object. All
6138 applications currently allocate this and many routines in the
6139 library use this. Affected file lib/silccrypt/silcrng.[ch].
6141 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
6142 it to use the Global RNG API.
6144 * Defined Authentication Payload into protocol specification that
6145 is used during SILC session to authenticate entities. It is
6146 used for example by client to authenticate itself to the server
6147 to obtain server operator privileges.
6149 Implemented this payload into the lib/silccore/silcauth.[ch].
6150 Implemented also routines for public key based authentication
6151 as the new protocol specification dictates.
6153 Moved definitions of different authentication methods from
6154 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
6156 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
6157 silc_pkcs_verify and silc_pkcs_sign_with_hash and
6158 silc_pkcs_verify_with_hash functions into the file
6159 lib/silccrypt/silcpkcs.[ch].
6161 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6163 * The client entry's userinfo pointer must be always valid.
6164 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
6165 will fail since it requires the userinfo. Now, the userinfo
6166 is allocated as "" if actual userinfo does not exist. Actually,
6167 it must exist and it is totally Ok to drop client connections
6168 that does not announce the userinfo. However, we will make
6169 this workaround for now.
6171 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
6172 to return the remote port by socket.
6174 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6176 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
6177 SILC_SERVER_PENDING_EXEC and added an new macro
6178 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
6179 data or when error occurs while processing the pending command.
6181 Added new argument `destructor' into silc_server_command_pending
6182 and to the SilcServerCommandPending object. This destructor is
6183 now called after calling the pending callback or if error occurs
6184 immediately. If error occurs the actual pending callback won't
6185 be called at all - only the destructor. The destructor may be
6186 NULL if destructor is not needed.
6188 All this applies for client library code as well. Similar
6189 changes were made there as well for the pending commands.
6191 In the client, the application must now allocate the
6192 SilcClientCommandContext with the silc_client_command_alloc
6195 * Added reference counter to the SilcServerCommandContext. Added
6196 function silc_server_command_alloc and silc_server_command_dup
6199 Same type of functions added to the client library for the same
6202 * Removed the cmd_ident from IDListData away since it is now
6203 global for all connections. It is the command identifier used
6204 in command sending and with pending commands. The affected file
6207 * Added reference counter to the SilcSocketConnection objecet to
6208 indicate the usage count of the object. The object won't be
6209 freed untill the reference counter hits zero. Currently only
6210 server uses this, and client ignores it. The client must be
6211 set to use this too later. The affected files are
6212 lib/silccore/silcsockconn.[ch]. Added also the function
6213 silc_socket_dup to increase the reference counter.
6215 This was mainly added because it is possible that the socket
6216 is removed underneath of pending command or other async
6217 operation. Now it won't be free'd and proper DISCONNECTING
6218 flags, etc. can be set to avoid sending data to connection that
6219 is not valid anymore.
6221 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
6222 the connection. After that it sets SILC_SET_DISCONNECTED.
6223 It is, however, possible that the socket data is not still freed.
6224 The silc_server_packet_process now checks that data is not
6225 read or written to connection that is DISCONNECTED. The socket
6226 get's freed when the reference counter hits zero.
6228 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6230 * Changed the client operation API: channel_message operation's
6231 `sender' is now the client entry of the sender, not the nickname
6232 and the `channel' is the channel entry, not the channel name.
6234 In the private_message operation the `sender' is now also the
6235 client entry of the sender not the nickname.
6237 Affected file is lib/silcclient/ops.h and all applications
6238 using the client operations.
6240 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6242 * Moved the calling of ops->connect() from connect_to_server_final
6243 into receive_new_id functin since that is the point when the
6244 client is actually allowed to send traffic to network. The
6245 affected file is lib/silcclient/client.c.
6247 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6249 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
6250 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
6251 (if needs broadcasting) instead of broadcasting the packets one
6252 by one which would make a burst in the network traffic.
6254 * Added `broadcast' argument to the functions in silcd/server.[ch]
6255 silc_server_create_new_channel[_with_id] to indicate whether
6256 to send New Channel packet to primary router.
6258 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6260 * Added new function into the silcd/server.[ch] files:
6261 silc_server_create_new_channel_with_id to create new channel with
6262 already existing Channel ID.
6264 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
6265 lib/silccore/silcpacket.h. This packet is used t send list of
6266 Set Mode payloads inside one packet. Server uses this to set
6267 the modes for the channels and clients on those channels, that it
6268 announced to the router when it connected to it. The protocol
6269 specification has been updated accordingly.
6271 * The silc_server_new_channel did not handle the packet coming
6272 from normal server as it normally does not send that. However,
6273 when it announces its channels it does send it. Implemented
6274 the support for that.
6276 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
6277 into the file lib/silccore/id.h.
6279 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6281 * Fixed memory leaks in the functions silc_idlist_del_client,
6282 silc_idlist_del_channel and silc_idlist_del_server in the file
6283 silcd/idlist.c. All of those leaked like a sieve.
6285 * Fixed some small memory leaks in the client's function
6286 silc_client_notify_by_server.
6288 * Added functions into silcd/server.c: silc_server_announce_clients,
6289 silc_server_announce_channels and silc_server_announce_server.
6290 These functions are used by normal and router server to announce
6291 to its primary router about clients, channels and servers (when
6292 router) that we own. This is done after we've connected to the
6295 These functions effectively implements the following packet types:
6296 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
6297 and SILC_PACKET_NEW_ID_LIST.
6299 * Added new functions into the silcd/packet_receive.[ch]:
6300 silc_server_new_id_list, silc_server_new_channel_list and
6301 silc_server_new_channel_user_list to handle the incoming
6302 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
6304 * Added support of changing Channel ID in the function
6305 silc_server_replace_id. If the server that announces a channel
6306 to the router already exists in the router (with same name but
6307 with different Channel ID), router is responsible to send
6308 Replace ID packet to the server and force the server to change
6309 the Channel ID to the one router has.
6311 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
6312 client that the Channel ID has been changed by the router. The
6313 normal server sends this to the client. Client must start using
6314 the new Channel ID as the channel's ID.
6316 Implemented handling of this new type into lib/silcclient/client.c
6317 into the function silc_client_notify_by_server.
6319 * Added new function silc_idlist_replace_channel_id into the files
6320 silcd/idlist.[ch] to replace the Channel ID.
6322 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6324 * Call silc_server_command_identify_check always when processing
6325 the IDENTIFY command in silcd/command.c
6327 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6329 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
6330 send keepalive packets. The packet can be sent by clients,
6331 servers and routers.
6333 Added function silc_socket_set_heartbeat into the file
6334 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
6335 If not set, the heartbeat is not performed. The actual
6336 heartbeat is implemented in the low level socket connection
6337 library. However, application is responsible of actually
6340 Added silc_server_send_heartbeat to send the actual heartbeat
6341 packet into silcd/packet_send.[ch]. Server now performs
6342 keepalive with all connections.
6344 * Added silc_task_get_first function into lib/silcutil/silctask.c
6345 to return the timeout task with shortest timeout. There was a bug
6346 in task unregistration that caused problems. TODO has been
6347 updated to include that task system must be rewritten.
6349 * The client library will now resolve the client information when
6350 receiving JOIN notify from server for client that we know but
6351 have incomplete information.
6353 * Rewrote parts of silc_server_remove_from_channels and
6354 silc_server_remove_from_one_channel as they did not remove the
6355 channel in some circumstances even though they should've.
6357 * Encryption problem encountered in server:
6359 The LEAVE command used to send the Channel Key packet to the
6360 router immediately after generating it. However, the code
6361 had earlier sent Remove Channel user packet but not immediately,
6362 ie. it was put to queue. The order of packets in the router
6363 was that Channel Key packet was first and Remove Channel User
6364 packet was second, even though they were encrypted in the
6365 reverse order. For this reason, MAC check failed. Now, this
6366 is fixed by not sending the Channel Key packet immediately but
6367 putting it to queue. However, this is more fundamental problem:
6368 packets that are in queue should actually not be encrypted
6369 because packets that are sent immediately gets encrypted
6370 actually with wrong IV (and thus MAC check fails). So, packets
6371 that are in queue should be encrypted when they are sent to
6372 the wire and not when they put to the queue.
6374 However, the problem is that the current system has not been
6375 designed to work that way. Instead, the packet is encrypted
6376 as soon as possible and left to the queue. The queue is then
6377 just purged into wire. There won't be any fixes for this
6378 any time soon. So, the current semantic for packet sending
6381 o If you send packet to remote host and do not force the send
6382 (the packet will be in queue) then all subsequent packets to the
6383 same remote host must also be put to the queue. Only after the
6384 queue has been purged is it safe again to force the packet
6387 o If you send all packets immediately then it safe to send
6388 any of subsequent packets through the queue, however, after
6389 the first packet is put to queue then any subsequent packets
6390 must also be put to the queue.
6392 Follow these rules and everything works fine.
6394 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6396 * Added new function silc_server_remove_clients_by_server to
6397 remove all client entries from ID list when the server connection
6398 is lost. In this case it is also important to invalidate all
6399 client entires as they hold the invalid server entry. This
6400 fixes fatal bug when server has lost connection and will reconnect
6403 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6405 * Made some sanity checks to silc_server_daemonise like to check
6406 whether the requested user and group actually exists.
6408 * Added sanity check to SKE's silc_ske_responder_finish to check
6409 that the public and private key actually is valid.
6411 * Invalidate the client's nickname when receiving Replace ID
6412 packet and the Client ID is being replaced. This means that the
6413 server will query the nickname if someone needs it (client)
6416 * Sort the ID Cache in client library when the ID Cache data
6417 has changed (needs sorting).
6419 * Do not allow for SILC client to create several connections to
6420 several servers. The client does not support windows right now
6421 and generating multiple connections causes weird behaviour.
6423 Irssi-silc client does support windows and can handle several
6424 connections without problems, see: www.irssi.org and SILC plugin.
6426 * Fixed some places where client was added to the IDList. The
6427 rule of thumb is following (in order to get everything right):
6428 If the client is directly connected local client then the
6429 `connection' argument must be set and `router' argument must be
6430 NULL to silc_idlist_add_client function. If the client is not
6431 directly connected client then the `router' argument must
6432 bet set and the `connection' argument must be NULL to the
6433 silc_idlist_add_client function.
6435 * The funtion silc_server_packet_send_local_channel actually did
6436 not check whether the client was locally connected or not. It
6437 does that now. Fixed a bug related to LEAVE command.
6439 * Fixed Remove Channel User payload parsing bug in server's
6440 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
6442 * The server's silc_server_save_channel_key now checks also the
6443 global ID list for the channel as it might not be in the local
6444 list. Fixed a bug related to LEAVE command.
6446 * Is this the end of the [<unknown>] buglet that has been lurking
6447 around for a long time? A little for loop fix in server's
6448 silc_server_command_whois_parse that is used by both IDENTIFY
6449 and WHOIS command. At least, this was a clear bug and a cause
6450 of one type of [<unknown>] buglet.
6452 * WHOIS and IDENTIFY commands call the function
6453 silc_server_command_[whois/identify]_check function even if
6454 we are not router server.
6456 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6458 * Added --with-gmp configuration option. If set the GMP
6459 is always compiled in the SILC source tree. If not set then
6460 it is checked whether the system has the GMP3 installed. If
6461 it has then the GMP won't be compiled (the system's headers
6462 and library is used), if it doesn't have it then the GMP is
6463 compiled in the SILC source tree.
6465 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6467 * Changed RSA private exponent generation to what PKCS #1
6468 suggests. We try to find the smallest possible d by doing
6469 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
6470 not security fix but optimization.
6472 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6474 * Added new config entry [Identity] to fork the server and run
6475 it as specific user and group. A patch from Bostik.
6477 * Imported Dotconf configuration library into lib/dotconf.
6478 This will be used to create the SILC configuration files later.
6479 It will appear in the distsribution after this commit.
6481 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6483 * A big code auditing weekend happening. Auditing code for
6484 obvious mistakes, bugs and errors. Also, removing any code
6487 Removed files for being obsolete:
6489 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
6490 inline in the file lib/silcutil/silcbuffer.h)
6492 o lib/silcutil/silcbufutil.c (the header has inline versions)
6494 Changed code to fix possible error conditions:
6496 o The buffer formatting routines now check that the destination
6497 buffer really has enough space to add the data. This applies for
6498 both buffer formatting and unformatting
6499 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
6500 unformatting was changed to accomodate following rules:
6501 XXX_*STRING_ALLOC will allocate space for the data into the pointer
6502 sent to the function while XXX_*STRING will not allocate or copy
6503 the data into the buffer. Instead it sets the pointer from the
6504 buffer into the pointer sent as argument (XXX_*STRING used to
6505 require that the pointer must be allocated already). This change
6506 makes this whole thing a bit more consistent and more optimized
6507 (note that the data returned in the unformatting with XXX_*STRING
6508 must not be freed now). The routines return now -1 on error.
6510 o Tried to find all code that use buffer_format and buffer_unformat
6511 and added return value checking to prevent formatting and
6512 especially unformatting errors and possible subsequent fatal
6515 o Changed ske->x and ske->KEY to mallocated pointers in
6516 lib/silcske/silcske.h. Fixed possible data and memory leak.
6518 o Added return value checking to all *_parse* functions. Fixed
6519 many memory leaks as well.
6521 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
6522 so that buffer overflows would not happen. All code now also
6523 checks the return value as it can fail.
6525 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6527 * Added reconnection support to server if the normal server looses
6528 its connection to the router (for example if router is rebooted).
6529 The server performs normal reconnection strategy implemented
6530 to the server. Affected file silcd/server.c.
6532 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6534 * Added new packet type SILC_PACKET_SET_MODE that is used to
6535 distribute the information about changed modes (for clients,
6536 channels and clients channel modes) to all routers in the
6537 network. Updated the protocol specification accordingly.
6539 Added functions into silcd/packet_send.c and
6540 silcd/packet_receive.c: silc_server_send_set_mode,
6541 silc_server_set_mode.
6543 Added new files silcmode.[ch] into lib/silccore that implements
6544 the encoding and decoding of Set Mode Payload. Added new type
6545 SilcSetModePayload. Moved the definitions of different modes
6546 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
6548 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6550 * Oops, a little mistake in server's connection authentication
6551 protocol. The protocol is not ended with FAILURE but with
6552 SUCCESS if the authentication is Ok. :) Affected file is
6555 * Implemented NICK_CHANGE notify handling in server in the file
6556 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
6557 the local clients on the channel. After the changing nickname
6558 in router environment snhould work and the [<unknown>] nickname
6559 should appear no more.
6561 The silc_server_replace_id function that receives the Replace ID
6562 payload now sends the NICK_CHANGE notify type also in the file
6563 silcd/packet_receive.c
6565 * Changed WHOIS and IDENTIFY command to support the maximum amount
6566 of arguments defined in protocol specs (3328 arguments). This
6567 fixed a bug that caused problems when there were more than three
6570 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6572 * Added extra parameter, command identifier, to the
6573 silc_client_send_command so that explicit command identifier
6576 Changed that ID list routines uses specific command identifier
6577 when sending WHOIS/IDENTIFY requests to the server so that they
6578 can be identified when the reply comes back.
6580 Affected files lib/silcclient/command.[ch],
6581 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
6583 * Added `sender' argument to silc_server_packet_send_to_channel
6584 to indicaet the sender who originally sent the packet to us
6585 that we are now re-sending. Ignored if NULL. Affected file
6586 silcd/packet_send.[ch].
6588 * Added some server statistics support in silcd/server_internal.h
6589 SilcServerStatistics structure and around the server code. Also
6590 send some nice statistics information when client is connecting
6593 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6595 * Fixed channel ID decoding in server's JOIN command reply in
6596 silcd/command_reply.c
6598 * Fixed braodcasting of replace ID payload to not to send it if
6599 we are standalone server in silcd/packet_receive.c.
6601 * Fixed all channel message sending routines to not to send
6602 packets to clients that has router set, since they are routed
6603 separately in the same function earlier. Affects file
6604 silcd/packet_send.c and all channel packet sending functions.
6606 * In USERS reply, res_argv[i] are not allocated, the table
6607 is allocated. Thus changed that free the table, not its
6610 * In server's whois_check and identify_check if the client is
6611 locally connected do not send any WHOIS commands - they are not
6614 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6616 * Fixed some minor bugs in client when sending WHOIS command. The
6617 arguments was in wrong order.
6619 * Removed statis function add_to_channel from server in
6620 silcd/command.c that was previously used with the joining but
6623 * Tested USERS command in router environment successfully with two
6624 routers, two servers and two clients.
6626 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6628 * Reorganized the USERS command and command reply in client library
6629 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
6630 When the command is given by user we register a pending command
6631 callback that will reprocess the command after the reply has been
6632 received from the server. When reprocessing the packet we then
6633 display the information. Thus, the USERS information is displayed
6634 now in the command callback instead of in the command reply
6635 callback. The processing of the command is same as previously
6636 when server has sent the command reply in the JOINing process.
6638 * Added to USERS command in silcd/command_reply.c to join the client,
6639 we didn't use to know about, to the channel after we've created
6640 a client entry for it. Also, for clienet we did know already still
6641 check whether it is on the channel or not and add it if not.
6643 * Removed silc_server_command_join_notify as the function and its
6646 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6648 * Changed the client's pending command handling to the same as the
6649 server's pending command handling. It is also now possible to
6650 execute command reply functions from other command reply
6651 function as the function callbacks for commands and command
6652 replies are one and same. The pending commands are not static
6653 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
6654 in client connection context. Thus, pending commands are server
6655 connection specific as it is convenient.
6657 Changed the function silc_client_command_pending and
6658 silc_client_command_pending_del and added new function
6659 silc_client_command_pending_check. Removed the
6660 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
6663 * Added cmd_ident, current command identifier, to the client
6664 connection context in lib/silcclient/client.h to keep track on
6665 command identifiers used in command sending. Client's command reply
6666 function handling now supports the mandatory command identifiers.
6668 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
6669 funtions in client to fully support pending command callbacks.
6671 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
6672 as one of the arguments to the application in the command reply
6675 * NOTE: The FORWARDED flag is depracated. It used to be depracated
6676 before first releasing SILC but came back. Now it is removed again
6677 and should come back nomore. The FORWARDED flag was used only
6678 by the JOINing procedure by forwarding the command packet to router.
6679 Now, the JOINing procedure has been changed to more generic (due
6680 to various router environment issues) and FORWARDED is not needed
6681 anymore for anything. The protocol specification is yet to be
6684 Now, removed silc_server_packet_forward from server and the flag
6685 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
6687 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6689 * Renamed NAMES command to USERS command. The NAMES was named that
6690 due to historical reasons. Now it is renamed. Also, rewrote
6691 parts of the USERS command. The nickname list is not sent anymore
6692 by the server. Only Client ID and mode lists are sent in the USERS
6693 command. Changed this also to the protocol specification.
6695 The client now resolves the names and stuff after it receives
6696 the USERS list from the server when joining to the channel.
6698 * WHOIS and IDENTIFY commands has been changed to support multiple
6699 Client ID's per command. One can now search for multiple users
6700 in the network by sending only one WHOIS or IDENTIFY command.
6701 Changed the code and the protocol specifications.
6703 * Removed silc_server_command_identify_parse and changed that IDENTIFY
6704 uses silc_server_command_whois_parse to parse the request. */
6706 * If normal server, do not parse the WHOIS and IDENTIFY requests
6707 before sending it to the router. Saves some time.
6709 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6711 * Fixed JOIN command on client library. Wrong number of arguments
6712 used to crash the client.
6714 * Added silc_server_channel_has_global function to check whether
6715 channel has global users or not.
6717 * Added silc_server_channel_has_local function to check whether channel
6718 has locally connected clients on the channel.
6720 * The silc_server_remove_from_one_channel now checks whether the
6721 channel has global users or not after given client was removed from
6722 the channel. It also checks whether the channel has local clients
6723 on the channel anymore. If it does not have then the channel entry
6724 is removed as it is not needed anymore.
6726 * The silc_server_notify now checks on JOIN notify whether the joining
6727 client is one of locally connected or global. If it is global then
6728 the channel has now global users on the channel and that is marked
6729 to the channel entry. Also, it now saves the global client to
6730 global list who is joining and JOINs it to the channel. This is
6731 for normal server, that is.
6733 Changed silc_server_send_notify_on_channel,
6734 silc_server_packet_relay_to_channel and
6735 silc_server_packet_send_to_channel check if we are normal server
6736 and client has router set (ie. global client) do not send the
6737 message to that client, as it is already routed to our router.
6739 * Implemented LEAVE notify type handling in silc_server_notify
6742 * Tested LEAVE command in router environment successfully. Tested
6743 with two routers, two servers and two clients.
6747 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
6749 * Implemented SIGNOFF notify type handling in silc_server_notify
6752 * silc_server_remove_id now removes the client entry from all channels
6753 it has joined and thusly sends SIGNOFF notify type.
6755 * Rewrote the NAMES list generation in server by removing two excess
6756 loops. The lists are created now inside one loop.
6758 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6760 * silc_server_remove_channel_user checks now also global list
6761 for channel and client.
6763 * silc_server_new_channel_user checks now both local and global
6764 list for channel and client. Fixed a bug in client id decoding.
6765 Used to decode wrong buffer.
6767 * silc_server_channel_message checks now both local and global
6768 list for channel entry.
6770 * Tested channel joining (hence JOIN) in router environment
6771 successfully. Tested with two routers, two servers and two
6774 * Tested channel message sending in router environment successfully.
6776 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
6778 * Added silc_server_save_channel_key into server.[ch] to save the
6779 received channel key in Channel Key payload processing. It is
6780 also used in JOIN command reply handling.
6782 Equivalent function silc_client_save_channel_key added into
6783 client.[ch] into client library.
6785 * Changed JOIN command reply to send information whether the channel
6786 was created or not (is existing already) and the channel key
6787 payload. Changed protocol specs accordingly.
6789 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
6790 the request was sent by ID and not by nickname. Crashed on
6793 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6795 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
6796 now correctly save the received data.
6798 * silc_server_free_sock_user_data now notifies routers in the
6799 network about entities leaving the network.
6801 At the same time implemented functions silc_server_remove_id
6802 and silc_server_send_remove_id to receive and send REMOVE_ID
6803 packets. The packet is used to notify routers in the network
6804 about leaving entities. The ID removed will become invalid in
6807 * Added function silc_idlist_del_server into server. Removes and
6808 free's server entry from ID list.
6810 * silc_server_private_message function now checks, if we are router,
6811 that the destination ID really is valid ID, naturally.
6813 * In router when NEW_ID packet is received (for new client) the
6814 hash of the Client ID is saved in the ID Cache but the
6815 client->nickname is set to NULL, instead of putting the hash
6818 IDENTIFY command now also checks that client->nickname must be
6819 valid. If it is not if will request the data from the server who
6820 owns the client. Added new function
6821 silc_server_command_identify_check.
6823 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
6824 to set the command to already allocated Command Payload.
6826 * Tested private message sending in router environment with two
6827 routers, two servers and two clients. Fixed minor bugs and now
6830 * Fixed segfault from client's NAMES command. Used to crash if
6833 * Forwarded packets must not be routed even if it is not destined
6834 to the receiver. Changed server code comply with this.
6836 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6838 * Added `require_reverse_mapping' boolean value to ServerParams
6839 structure. If TRUE (not default) the server will require that
6840 the connecting host has fully qualified domain name.
6842 If the reverse mapping is not required and hostname could not be
6843 found the IP address is used as hostname.
6845 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6847 * Implemented version string checking to both client and server.
6848 The check is incomplete currently due to the abnormal version
6849 strings used in development version of SILC.
6851 * Changed all command functions in server to use the new
6854 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6856 * Changed char *data to unsigned char *data in ID Cache system to
6857 support binary data as ID Cache data. Changed code to support
6858 binary data in lib/silccore/idcache.c.
6860 * Renamed silc_server_packet_relay_command_reply to
6861 silc_server_command_reply as it is normal packet receiving
6862 function. Rewrote the function to accept command replys for
6863 servers and not only for clients.
6865 * Mark remote router always as registered server if we are connecting
6866 to it. Otherwise, commands sent by the router to us are ignored.
6868 * All ID List find routines now returns the ID Cache Entry pointer
6869 as well if requested.
6871 * WHOIS command works now in router environment, tested with two
6872 routers, two servers and two clients.
6874 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
6875 in router environment (as it is almost equivalent to WHOIS) but
6876 hasn't been tested thoroughly. Added new functions:
6878 silc_server_command_identify_parse
6879 silc_server_command_identify_send_reply
6880 silc_server_command_identify_from_client
6881 silc_server_command_identify_from_server
6883 * Disabled route cache adding because adding two different ID's with
6884 same IP replaces the old cache entry thus giving wrong route.
6885 The entry->router->connection is always the fastest route anyway
6886 so route cache may not be needed. Of course, new routes maybe
6887 established after receiving the ID when the entry->router->connection
6888 might not be anymore the most optimal.
6890 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6892 * Add route cache for received ID for fast routing.
6894 * Added silc_server_packet_route to route received packet on router
6895 that is not destined to us.
6897 * Renamed silc_server_get_route to silc_server_route_get.
6899 * Added id_string and id_string_len fields into SilcServer to
6900 include encoded ServerID for fast comparing without excess
6901 encoding of the ID's.
6903 * Cleaned up WHOIS command on server side. Added following static
6906 silc_server_command_whois_parse
6907 silc_server_command_whois_check
6908 silc_server_command_whois_send_reply
6909 silc_server_command_whois_from_client
6910 silc_server_command_whois_from_server
6912 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
6913 arguments in command replies. All command functions should be
6914 updated to use this macro.
6916 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6918 * Minor typo fixes on command reply handling on server.
6920 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6922 * Added silc_server_command_add_to_channel internal routine to add
6923 the client to the channel after router has created the channel and
6924 sent command reply to the server.
6926 * Added generic silc_server_send_command to send any command from
6929 * Use static buffer with ID rendering instead of duplicating data.
6931 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6933 * Fixed a channel user mode bug when joining to a channel server gave
6934 everybody channel founder rights, oops.
6936 * We mark ourselves as the router of the incoming server connection
6937 if we are router ourselves. This way we can check in some packet
6938 sending functions whether it is locally connected server. For
6939 incoming router connections we put NULL.
6941 * For router sending packets locally means now always sending the
6942 packet cell wide; to local clients and local servers. For normal
6943 server sending packet locally means sending it to only local
6946 * Fixed the JOIN command to really work in router environment. If the
6947 channel is created it is always created by the router. Router is
6948 also responsible of making the initial joining to the channel,
6949 sending JOIN notify to the sending server and distributing
6950 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
6951 does not exist server doesn't do anything else but forward the
6952 command to the router which performs everything.
6954 * Added silc_server_send_channel_key function to send the Channel Key
6957 * Added silc_server_create_channel_key to create new channel key. The
6958 channel key is now re-generated everytime someone joins or leaves
6959 a channel, as protocol dictates. Note: channel->key_len is the
6962 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6964 * Splitted server.[ch] finally. Created now packet_send.[ch] and
6965 packet_receive.[ch] to separate packet sending and receiving
6966 routines. The server.[ch] now includes everything else including
6967 actual packet processing (writing and reading data) and other
6970 Renamed silc_server_private_message_send_internal to
6971 silc_server_send_private_message. The routine is still though
6972 used only to relay private messages as server does not send
6973 private messages itself.
6975 Renamed silc_server_new_channel to silc_server_create_new_channel
6976 and added new function sicl_server_new_channel that handles the
6977 incoming New Channel packet. Added also new sending function
6978 silc_server_send_new_channel to send New Channel Payload.
6980 * Added new function silc_server_notify to process incoming notify
6981 packet to the server/router. Server may then relay the notify
6982 to clients if needed.
6984 * Added new function silc_server_new_channel_user to process incoming
6985 New Channel User packet. Router will redistribute the packet and
6986 send JOIN notify to its local clients and locally connected servers
6987 if needed. Normal server will send JOIN notify to its local client
6988 on same channel when received this packet. Added also corresponding
6989 sending function silc_server_send_new_channel_user to sent the
6992 * Added boolean route argument to send_notif_to_channel and
6993 packet_send_to_channel functions to attempt to route the packet
6994 if it is TRUE and send only locally if it is FALSE.
6996 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
6998 * silc_server_replace_id now broadcasts the received replace ID
6999 packet if it is not broadcast packet already. The router must
7000 broadcast to inform other routers about changed ID.
7002 * Added backpointer to server's router into SilcServer context in
7003 silcd/server_internal.h.
7005 * Fixed silc_server_packet_broadcast to send correct broadcast
7008 * The channel key is now distributed to the local client as soon
7009 as it is received from the router (in router environment) so that
7010 no other packet may be sent for the channel until client has
7013 * silc_server_remove_channel_user now broadcasts the received
7014 Remove Channel User packet if it is not broadcast packet already.
7015 The router must broadcast to inform other routers about removed
7018 * Added users field into SilcPacketContext that is a reference count
7019 of the context. One can increase the reference count by calling
7020 silc_packet_context_dup which is now changed to just increase the
7021 reference count instead of duplicating the data. The reference
7022 count is decresed by calling silc_packet_context_free that will
7023 free the data after the reference count hits zero.
7025 For now on the packet context and everything allocated into it
7026 (including the raw packet from network) must be freed by calling
7027 the new silc_packet_context_free function. Added also new function
7028 silc_packet_context_alloc that must be used now to allocate the
7029 context. This also means that if a routine is asynchronous from
7030 silc_[client/server]_packet_parse_type the packet context must
7031 be duplicated by calling silc_packet_context_dup. Otherwise it
7032 gets free'd after silc_[client/server]_packet_parse_type returns.
7033 Also, one must remember that if packet is duplicated then its
7034 reference count must be decresed by calling the free function as
7035 many times as it was duplicated.
7037 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
7038 from both client and server.
7040 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7042 * Made joining to a channel working in router environment.
7044 * Cleaned up JOIN command on server side and create function
7045 silc_server_command_join_channel internal routine to make the
7048 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7050 * Changed silc_command_pending list to SilcDList. Also, added
7051 `ident' field to SilcServerCommandPending structure to identify
7052 the reply and to call correct callback.
7054 Added silc_server_command_pending_check function to replace the
7055 corresnponding macro. The silc_command_pending list is not
7058 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
7059 to set identifier to previously allocated Command Payload. It
7060 is used to set identifier for command when resending Command
7063 * Added silc_command_payload_encode_payload to encode Command
7064 Payload buffer from SilcCommandPayload structure.
7066 * Added silc_argument_payload_encode_payload to encode Argument
7067 payload buffer from SilcArgumentPayload structure.
7069 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7071 * Changed WHOIS command to support router connection on server side.
7072 The whois request is always sent to router unless the server is
7073 standalone server. After server has received the reply from the
7074 router will it send the reply to the client.
7076 * Added silc_server_packet_broadcast into silcd/server.[ch] to
7077 broadcast received broadcast packet. The function is used only
7078 by router. The broadcast packet is always sent to the router's
7081 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
7082 render given ID to printable string, for log files for example.
7084 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7086 * Made basic router to router connections working. At least they
7087 can now connect to each other but nothing really works the way
7088 they are supposed - yet.
7090 * Added new initiator token to RouterConnection configuration
7091 file in silcd/serverconfig.[ch]. It is used to tell whether we
7092 are the initiator to the remote router or whether we'll expect
7093 the other end to connect.
7095 * Moved registering of listener task to silc_server_init, hence
7096 the server starts listenning as soon as it is run, even if it
7097 does not have connections to other routers. Let's see how well
7100 * Changed default connection retry timeouts for more suitable in
7103 * Removed cipher and such arguments from silc_idlist_add_client
7104 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
7105 Added new function silc_idlist_add_data to add the keys and stuff
7108 * Added SilcIDListData structure and added it to SilcClientEntry
7109 and SilcServerEntry as their first field in the structure. This
7110 way we can explicitly cast the ID entries to the SilcIDListData
7111 structure and get common data for the entries. In past, we had
7112 to first check what type of connection it is and then cast it to
7113 correct ID entry type. Now, we can directly cast the opaque
7114 pointer to the SilcIDListData (no matter what ID entry it actually
7115 is) and get the data needed.
7117 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7119 * Wow, found a bug in scheduler. The scheduler uninitialized itself
7120 in some circumstances even if threre were timeout tasks, though not
7121 IO tasks, but tasks anyway. Now fixed.
7123 * Defined SilcServerConnection structure to hold connection specific
7124 stuff about directly connected servers and routers. The definition
7125 is currently in silcd/server_internal.h. I thought about having
7126 a bit more important role fro this struct but for now it is used
7127 only when connecting to other server (or router actually).
7129 * Added connecting retry support in server when connecting to
7130 router(s). The retry feature implement exponential backoff
7131 algorithm. Also, added SilcServerParams structure to hold default
7132 parameters for server. For now, it include these retry settings
7133 and are hard coded. After server is moded to be as Silc Server
7134 Library this structure will be more important.
7136 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7138 * Changed client librarys channel->clients table to SilcList and
7139 changed code accordingly.
7141 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7143 * Changed client's channel table to SilcList and changed code
7144 accordingly. Also changed SilcChannelClientEntry to include back-
7145 pointer to the channel so that client entry can use that structure
7146 as list as well and we have fast cross-reference to the channel.
7147 This change dramatically decreased the complexity of channel
7148 handling with client entry and vice versa (removed one extra
7149 loop when searching for channel entry from many functions).
7151 * Changed server->sim from table to SilcDList and changed code
7154 * NAMES command can now be used from user interface. It will show
7155 the user list on the channel, neatly.
7157 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
7158 Code now saves realname of the user if it becomes available.
7160 * Renamed configure.in to configure.in.pre and made ./prepare
7161 script to automatically add correct version string to
7162 configure.in which it creates from configure.in.pre.
7164 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7166 * NAMES command reply now shows users mode with the nickname when
7169 * Moved silc_client_ch[u]mode[_char] functions from
7170 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
7171 place sucks, they are utility functions and should be in some
7174 * Fixed some unsigned int's to unsigned short's. Patch by cras.
7176 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
7179 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7183 * Added TRQ (efficient deque and list library) into lib/trq. This is
7184 a very good list library that is currently used in the SILC. Defined
7185 SilcList API over the library because I didn't like the API very
7186 much. See lib/trq/silclist.h for the API and examples of how to
7187 use the API. Fixed various places in the code to use the new
7188 SilcList API. The SilcList is meant for lists that has a structure
7189 already defined as a list. It is not suitable to add just some
7190 context to the list (in TRQ, the context is the list actually).
7192 So, I defined SilcDList that can be used for the purpose where
7193 predefined list structure does not exit. This can be used as
7194 such list. Now some context just can be added to the SilcDList.
7195 Currently this list is not used in the SILC just yet, though there
7196 are a lot places where this can replace dynamically allocated
7197 tables and I will fix these places, later, to use SilcDList.
7198 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
7199 and use TRQ internally).
7201 Also fixed some annoying warning messages that the original TRQ
7202 code generated. Also minor changes to TRQ's Makefile.in.
7204 * Added support for querying by Client ID to both WHOIS and
7205 IDENTIFY commands into server, as required by the protocol.
7207 * Removed method function pointers from SilcBuffer structure. They
7208 weren't used to anything and just increased the context size for
7209 no good reason. This change also made silc_buffer_alloc and
7210 silc_buffer_free functions inline functions.
7212 * Disabled command flooding detection support until it's fixed so
7213 that it accepts commands in but does not execute them more than once
7216 * Added silc_net_localhost(), to return local hostname, into
7217 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
7218 that must be initialized before calling silc_client_init.
7220 * Added new function: silc_server_send_notify_on_channels to send
7221 notify messages to all channels client has joined. It is assured
7222 that the message is sent only once per client.
7224 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
7225 lib/silcutil/silcutil.[ch] as silc_format function. The new
7226 function is generic and is used by server as well, not only by
7227 the logging routines.
7229 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
7230 the provided version string was not acceptable. Added new function:
7231 silc_ske_check_version into lib/silcske/silcske.h. The function
7232 must be implemented by the application (client or server) and it
7233 does not reside in the SKE library. The function checks the version
7234 string remote end sent.
7236 * Added back pointers (to opaque context and to SilcSocketConnection)
7237 into SilcPacketContext structure into lib/silccore/silcpacket.h.
7239 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
7240 duplicate packet context structure.
7242 * Changed `notify' client operation to send same arguments as client
7243 receives from server except for ID's. ID's are mapped to correct
7244 ID entry and that is returned. Also, if channel entry is not sent
7245 by server but the notify is for channel the channel entry is sent
7246 to application (otherwise application doesn't know that it is for
7247 channel (library gets it from packet's Destination ID)).
7249 * Added silc_client_remove_from_channels into client library to
7250 remove a client from all channels it has joined to. Used when
7251 received SIGNOFF notify from server. Added also new function
7252 silc_client_replace_from_channels to replace old ID entry with
7253 new ID entry on all channels. Used when received NICK_CHANGE
7256 * Fixed ID Cache list handling in silc_idlist_get_client in
7257 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
7258 to get (or query) client by ID.
7260 * Updated TODO list.
7262 * Added connection authentication status message defined by the
7263 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
7264 support for these into the code in client and server side.
7266 * Added generic function silc_client_send_command to send any command
7267 with variable argument list. Application should use this function
7268 to send commands if the command functions provided by the library
7269 does not suite for the application's user interface needs.
7271 * Added new `failure' client operation. Application is notified about
7272 received failure packet if client is executing a protocol. In this
7273 case the protocol's execution has failed.
7275 * Added SKE's end notify to send the SKE_SUCCESS notify message that
7276 is required by the protocol.
7278 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
7279 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
7282 * Added status flag to SilcSKE object to indicate realtime status
7283 of the SKE protocol.
7285 * Application receives now exactly same command reply arguments as
7286 the library receives from server. However, if ID is received the
7287 corresponding ID entry is returned to the application (eg. Client
7288 ID is mapped to correct SilcClientEntry entry and that is returned).
7289 Changed command_reply client operation due to this change.
7291 * Changed all ID's in commands and in command replys as ID Payloads.
7292 Change affected both client and server side codes.
7294 All ID's sent in SILC network (with execption of ID's in SILC
7295 Packet header) are sent in ID Payload to support variable length
7298 * Server now notifies nick changes and notifies all clients on
7299 the channels about the new nickname (about the new Client ID,
7302 * Implemented CMODE command to change channel modes. Supports all
7303 channel modes defined by the protocol specs except ban and invite
7304 lists. (Also, private channel key mode is supported but support for
7305 setting private channel key in client is missing, thus, this mode
7306 has no effect on client side (except that server requires that the
7307 client uses private channel key and normal channel traffic does not
7310 Also, invite mode works per se, but INVITE command does not work
7311 yet correctly, so you can set channel as invite only channel but
7312 inviting clients to the channel does not work (it is yet to be
7313 thought what's the best way to do it).
7315 * Added new command SILC_COMMAND_CUMODE to change user mode on the
7316 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
7317 Implemented CUMODE command to change user's mode on the channel.
7318 Supports all modes defined by the protocol specs.
7320 * Added NAMES command reply to return users modes on the channel.
7322 * Removed unnecessary and slow ciphers from lib/silccrypt.
7324 * Set SO_KEEPALIVE option to connection sockets by default.
7326 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
7328 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
7329 redefined the Notify Payload into protocol specs.
7331 * Added silc_id_payload_parse_id to get ID directly from raw
7334 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7336 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
7337 accept searching by Client ID as well.
7339 * Added support for LEAVE and SIGNOFF notify types in client library.
7341 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
7342 to parse ID Payload from raw data.
7344 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7346 * Added flags parameter into silc_ske_assemble_security_properties
7347 function in lib/silcske/silcske.[ch].
7349 * Changed notify client operation to fit better for notify messages
7350 sent by server. The notify payload received from server is now
7351 passed to the application (after parsing it to SilcNotifyPayload).
7352 It is application's responsibility to retrieve the arguments
7353 from the payload and show the message the way it wants. The message
7354 sent by server is implementation specific.
7356 * Changed public keys to comply with the protocol specification.
7357 Old public keys are not supported anymore and are not compatible.
7359 * Removed nickname from Channel Payload as the latest draft removed
7360 it. The client must resolve the nickname from the NAMES command
7361 reply received when it joined the channel.
7363 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
7365 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7367 * Fixed some errors in protocol specification drafts.
7369 * Created lib/silccore/silcnotify.c to implement Notify Payload
7370 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
7371 generic payloads described by protocol specifications. The file
7372 includes implementations for ID Payload and Argument Payload.
7374 * Changed Command Payload implementation to use the new Argument
7375 Payload. Changed command_xxxx_payload to command_payload_xxxx
7376 to comply with SILC coding conventions.
7378 * Added suppport for Argument Payload handling in Notify Payload
7379 implementation as protocol requires it. Added the new support
7380 into server and client lib as well.
7382 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7384 * Added support for multiple nicknames on same channel. [n] is
7385 added locally to the nickname if there are more than one same
7386 nicknames on the channel.
7388 * Server now sends all nicknames that matched WHOIS request.
7389 Client also shows the list received from server.
7391 * Added TOPIC command to client side. User can now set and show
7392 current topic on channel.
7394 * Added MOTD command to client and server. Also, server sends the
7395 motd when client connects to the server.
7397 * Changed version strings to comply ISO 8601.
7399 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7401 * Fixed protocol error handling in client library. It should now
7402 cope even if the SKE fails for some reason.
7404 * Made new protocol specification drafts for submitting to IETF.
7406 * Implemented TOPIC command to server in silcd/command.c.
7408 * Added two new notify types into lib/silccore/silcnotify.h:
7409 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
7410 notify nickname change and topic setting/change on a channel.
7412 * API change of command_reply operation in client library. The
7413 application gets now the status type received from server as well.
7415 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7417 * Removed the function just added to lib/silcutil/silcschedule.[ch].
7419 * Cras fixed and optimized the packet handling even further and
7420 it should work now. Minor change to the prototype of function
7421 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
7423 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7425 * Added new function into lib/silcutil/silcschedule.[ch]:
7426 silc_schedule_with_fd to select() a specified fd. The function
7427 returns after timeout expires or data arrives or goes. The
7428 function is used by packet routines to wait that all data is
7429 received from network.
7431 * Fixed data reading from network in lib/silccore/silcpacket.c.
7432 The code now assures that all data is read from the fd and then
7433 continues packet processing. This was a bug fix since the code
7434 used to drop some data in some circumstances.
7436 * Added new function into lib/silcclient/client.[ch]:
7437 silc_client_start_key_exchange to start key exchange after
7438 connection has been established to server. The code internally
7439 now uses this funtion but its main purpose was to provide it
7440 for applications that perform their own connecting. After
7441 application has created a connection it merely calls this
7442 function to start the key exchange between client and server.
7443 The library takes care of everything else after that.
7445 Updated also lib/silcclient/README to explain the usage of
7448 * Do not send to application information that connection has
7449 been established. Application gets notified it by connect
7452 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7454 * Applied cras's patch to add silc_schedule_one function. The
7455 function runs scheduler once and returns.
7457 * Fixed the scheduler after cras messed it up. The timeout
7458 handling works now as it's supposed to work.
7460 * Added into lib/silccore/ silcnotify.h to include notify
7461 message types support. Changed silc_server_send_notify*
7462 functions, in server.[ch], to support those new notify types.
7463 Added the support for the notify types into client library,
7464 as well. Added new notify client operation into ops.h in
7467 * Changed silc_server_packet_send_to_channel to send normal
7468 packets instead of just channel message packets. The function
7469 is now used to send the notify packets to channels. It is not
7470 used to send channel message packets anymore, as server never
7473 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
7474 va_arg()s as it seems to require it nowadays. I guess, if SILC
7475 is compiled with older va_arg() the new code should work anyway.
7477 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7479 * Splitted core library. Core library (lib/silccore) includes
7480 now only SILC protocol specific core (and common) components.
7481 Created new utility library (lib/silcutil) that includes more
7482 generic purpose stuff. The stuff for util library was taken
7483 from the old core library. This was minor and easy split.
7485 * Created SILC Client Library (lib/silcclient) that includes
7486 implementation of the SILC client without user interface. This
7487 was major move from silc/ directory. The code has been changed
7488 so that it is transparent towards the user interface. The
7489 silc/ directory includes now the same user interface as before
7490 and it uses the new client library. Read lib/silcclient/README.
7491 Basicly, the client library performs everything else related
7492 to SILC except user interface handling. Also, configuration
7493 files are considered to be part of user interface and library
7494 does not handle them.
7496 This change also changed a lot of structures, function naming etc.
7497 Most important change was that SilcClientWindow object was
7498 renamed to SilcClientConnection in the client library. Created
7499 also new file lib/silcclient/ops.h. Also added new files
7500 silc/local_command.[ch] and silc/client_ops.[ch].
7502 All these changes were made to make it easier for user interface
7503 designers to create what ever user interface for the SILC client
7506 It is also expected that the server will be moved to lib
7507 directory as well and SILC Server Library will be created;
7508 sometimes in the future.
7510 * Removed Local commands from lib/silccore/silccommand.h as
7511 they are application specific and new client library does not
7512 handle any of those anymore.
7514 * Several functions moved to lib/silcutil/silcutilc.[ch] from
7515 old client implementation in silc/.
7517 * Added support for callback functions in SILC_LOG_* macros.
7518 Application can now set its own callbacks that will be called
7519 instead of using the default functions that will always print
7520 the debug messages to stderr (or stdout). Also, debugging can
7521 now be disabled by setting silc_debug to FALSE and re-enabled by
7522 setting it to TRUE. Note, that logging will still work even
7523 if debugging is disabled.
7525 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
7526 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
7527 silc_log_reset_debug_callbacks.
7529 * To enable debugging in silc client one must give now -d
7530 option on command line.
7532 * Changed silc_schedule_init to automatically allocate task queues
7533 if they are not allocated before calling it.
7535 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7537 * Added GMP 3.1 into math library.
7539 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7541 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
7542 a channel in SILC network. The packet is used by servers and
7543 routers to notify other routers that user has left a channel.
7544 This little feature was missing until now. Added the feature
7545 to protocol specification as well.
7547 Added functions: silc_server_send_remove_channel_user and
7548 silc_server_remove_channel_user into server.[ch].
7550 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
7551 lib/silccore/silcpacket.h. However, they are not implemented
7554 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7556 * Fixed joining to a channel and sending channel messages
7557 between server and router. The channel message sending should
7558 now work inside a cell.
7560 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7562 * Fixed the private message sending between server and router.
7563 The private message sending should now work inside a cell.
7565 * Added silc_server_replace_id into server.[ch] to replace
7566 existing ID in the SILC network.
7568 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
7569 and silc_idlist_replace_server_id into idlist.[ch] in server.
7571 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7573 * Fixed the server to server connections. Server can again now
7574 connect to router. Router to router connections probably does
7577 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7579 * Added dynamic protocol registering support. Now protocols can
7580 registered and unregistered on the fly. Patch by cras.
7582 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7584 * Added lib/contrib directory to hold routines that some platforms
7585 don't have but are needed by SILC.
7587 * Added getopt.c, getopt1.c and getopt.h from GNU C library
7588 into lin/contrib to provide getopt() and getopt_long() for
7589 those who don't have it.
7591 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7593 * Added AWAY command to client. When away message is set and
7594 client receives a private message packet the client automatically
7595 replies to the sender with the away message.
7597 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
7598 bug seemed to be the cause of recent problems when compiling
7601 * Added version detection support to SKE protocol specification
7602 and added the new changes to the SKE implementation as well.
7603 There were other minor changes in the SKE protocol as well.
7605 Many changes in lib/silcske/silcske.[ch] and in
7606 lib/silcske/payload.[ch].
7608 * Added ^U functionality, clear input line. Patch from cras.
7610 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7612 * Mainly small bugfixes on core library. Fixed some debugging
7613 logging and buffer overflow in silclog.c.
7615 * Updated config.sub and config.guess on the distribution tree.
7617 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7619 * Added command lagging support in server. Client may execute
7620 commands now only once in two seconds.
7622 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7624 * Optimized packet reception. MAC computation and checking is now
7625 also more optimized. A lot previously duplicated code is now
7626 used as generic by both client and server.
7628 * Fixed key pair generation in clientutil.c
7630 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7632 * Added into lib/silccore/silcbufutil.[ch] new function;
7633 silc_buffer_realloc.
7635 * Moved generic packet sending/encryption functions to
7636 lib/silccore/silcpacket.[ch] from client and server. Some
7637 rewriting of the functions.
7639 * Moved all generic packet reception/decryption functions to
7640 lib/silccore/silcpacket.[ch] from client and server. The
7641 packet processing is now much cleaner in both client and server.
7642 These were major changes in both client and server.
7644 * Created many common functions in server to do packet sending.
7645 Previously code were duplicated a lot, this has been removed
7648 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7650 * Rewrote major parts of the ID cache system. Don't know
7651 whether it is better now or not but at least the API is more
7654 * Major rewrite on ID cache stuff on client because of the ID
7655 cache API changes. Added idlist.c to client.
7657 * Also major rewrite on ID cache stuff on server as well.
7658 Major rewrite of idlist.[ch]. SilcXXXList's are now named
7659 SilcXXXEntry's. We won't keep anymore idlist specific pointers
7660 in hand, instead they are all put into the ID cache system now.
7661 All server_idlist_* routines uses ID cache now instead of
7662 traversing its own lists (those lists does not exist anymore).
7663 SilcIDList though still exists. Also, SilcXXXEntry's are
7666 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7668 * Finally made the SKE implementation compliant to the protocol
7669 specification. All mp integers are now binary encoded as
7670 opposed being HEX encoded.
7672 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
7675 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
7676 functions: silc_[encode/decode]_pem. Also added function
7677 silc_encode_pem_file to PEM encode with newlines ('\n') for
7680 * SILC public keys are now encoded either PEM or binary. Same
7681 option is for private keys as well. By default private keys
7682 are binary encoded and public keys PEM encoded. Silly HEX
7683 encoding were removed.
7685 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
7686 function to create fingerprints.
7688 * Fixed a bug in SHA1; does not change the original data anymore.
7690 * Partly implemented INFO command on client and server side.
7691 Fixed CLEAR command. Changes to SERVER command; show current
7692 server(s) when giving command without arguments. Added
7693 VERSION command to client.
7695 * Added check to server that unregistered connections cannot
7696 execute commands (unless it is specificly allowed).
7698 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7700 * Fixed screen refresh.
7702 * Fixed channel joining bug from client. On some circumstances
7703 client tried to join to a channel it had already joined.
7705 * Added public key verification process into client's protocol.c.
7706 The client now verifies the public key from user and saves
7707 it into ~./silc/serverkeys/ directory.
7709 Added into: clientutil.[ch]: silc_client_verify_server_key.
7711 * Changed SKE protocol's silc_ske_initiator_finish function
7712 to accept callback function that verifies the received public
7713 key. Removed old silc_ske_verify_public_key function.
7715 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7717 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
7718 silc_pkcs_private_key[_data]_set.
7720 * Made the password and public authentication more cleaner in
7721 server's protocol.c.
7723 * Removed historic and obsolete protocol `channel_auth' from
7724 both client and server.
7726 * Removed wrong way of sending command status messages from
7727 server to client in server's command.c. The old way violated
7728 protocol specification.
7730 Changes to silccore/silccommand.[ch]: removed
7731 silc_command_encode_status_payload -> not needed anymore,
7732 changed silc_command_encode_payload_va to accept extra
7733 argument on variable argument list. The argument type must
7734 now be provided to the function. Also, added new function:
7735 silc_command_encode_reply_payload_va which is same as
7736 normal command_encode_payload_va except command status type
7737 is provided as extra argument.
7739 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7741 * Added ~./silc directory handling. The directory includes the
7742 public and private keys for the client.
7744 Added silc_client_check_silc_dir, silc_client_create_identifier
7745 and silc_client_load_keys.
7747 * Implemented SILC protocol compliant public key. Added public
7748 and private key saving to and loading from files.
7750 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
7751 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
7752 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
7753 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
7754 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
7756 Implemented: silc_pkcs_save_[public/private]_key[_data] and
7757 silc_pkcs_load_[public/private]_key.
7759 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7761 * Added silc_server_get_route (route.[ch]) to get connection
7762 data for the fastest route for given ID.
7764 * Implemented INVITE command on client and server. The command
7765 were re-defined in the SILC Protocol Specification and the
7766 implementation now complies with the specification.
7768 * Implemented PING command on client and server.
7770 * Implemented NAMES command on client and server. The server side
7771 supports currently only normal server not router server yet.
7772 Some changes to NAMES definition in SILC protocol specification.
7774 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7776 * Implemented LEAVE command on client and server.
7778 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
7779 again. This change was made to the protocol as well. Server
7780 should not violate the protocol specification anymore.
7782 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
7784 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
7785 was tested. SOCKS4 was not but should work anyway.
