1 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added new function silc_string_regexify that converts string
4 including wildcard characters into regex string that can
5 be used by the GNU regex library. Added into the file
6 lib/silcutil/silcutil.[ch].
8 Added silc_string_regex_combine to combine to regex strings
9 into one so that they can be used as one regex string by
10 the GNU regex library. Added into the file
11 lib/silcutil/silcutil.[ch].
13 Added silc_string_regex_match to match two strings. It returns
14 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
16 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
18 * Imported GNU regex to the soruce tree into lib/contrib.
19 Fixed some compiler warning from the regex.c.
21 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
23 * Fixed MOTD command in the server to work in router environment.
25 * Fixed the MOTD command in the client library to support
26 the server argument in the command.
28 * Added `nickname_len' argument to the silc_idlist_add_client
29 in the server, as the `nickname' argument may be binary data
32 * Added silc_idlist_get_channels to return all channels from
35 * Implemented LIST command to the server. Affected file is
38 * Implemented the LIST command to the client library and on the
41 * Added [<user count>] argument to the LIST command reply.
42 With private channels the user count is not shown.
44 * Updated TODO and README.
46 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
48 * The client entry's data.registered must be TRUE even with
49 global client entry on global client list. The data.registered
50 is used to check whether the client is anymore in the network,
51 for example with WHOWAS command so it must be valid.
53 * Fixed the WHOWAS command in the server. It now actually works
54 in router environment. Added function into silcd/command_reply.c
55 silc_server_command_reply_whowas_save.
57 * Added silc_idlist_purge function to the silcd/idlist.c
58 to periodically purge the ID Cache.
60 * Fixed INFO command in the server. It works now in router
61 environment. Added <server name> argument to the INFO command
62 reply. Updated the protocol specs.
64 * Fixed minor bug in silc_idcache_purge to not purge if the
67 * Fixed various bugs in WHOIS and IDENTIFY command handling as
68 they were buggy because of the WHOWAS information.
70 * Fixed local command MSG to handle the async resolving of
71 the remote client properly. It used to fail the first MSG.
72 Affected file silc/local_command.c.
74 * Added `data_len' field to SilcIDCache context.
76 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
78 * Update TODO. Todo in commands in the server.
80 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
82 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
83 used by routers as broadcast packet to inform other routers
84 about the changed user mode.
86 Implemented the notify handling in the server. Affected file is
87 silcd/packet_receive.c. Added the function
88 silc_server_send_notify_umode to the silcd/packet_send.[ch].
90 * Added new generic Channel Payload and deprecated the New Channel
91 Payload. The New Channel Payload is now the generic Channel
94 * Added new argument `mode' to the silc_server_send_new_channel
95 as it is required in the Channel Payload now.
97 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
98 and created a new and real SilChannelPayload to represent the
99 new generic Channel Payload. Implemented the encode/decode
100 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
102 * Added silc_server_get_client_channel_list to return the list
103 of channels the client has joined for WHOIS command reply.
104 Affected file silcd/server.[ch].
106 * Implemented the channel list sending in the WHOIS command reply
107 in server and in the client.
109 Implemented the channel list displaying on the user interface
110 as well. Affected file silc/client_ops.c.
112 * Added silc_channel_payload_parse_list to parse list of Channel
113 Payloads. It returns SilcDList list of SilcChannelPayloads.
114 Client for example can use this function to parse the list of
115 channels it receives in the WHOIS command reply. The caller
116 must free the list by calling silc_channel_payload_list_free.
117 Affected files lib/silccore/silcchannel.[ch].
119 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
121 * Added one new argument <user mode> to the WHOIS command reply
122 to return the mode of the user in SILC. Updated the protocol
125 Implemented it to the server and client.
127 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
129 * Fixed the mode printing on the user interface on joining.
130 Affected file silc/client_ops.c.
132 * Implemented the UMODE command and user modes in general to the
133 client library and to the user interface.
135 * Implemented the UMODE command to the server.
137 * The server now sends UNKNOWN_COMMAND error status if client sends
138 unknown command. Affected file silcd/command.c.
140 * All server commands now handle the command identifier the right
141 way when sending the command reply to the client. The client can
142 use to identify the command replies with the identifier.
144 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
146 * Added silc_server_get_client_route to resolve the route to
147 the client indicated by the client ID. Affected file is
150 * Added silc_server_relay_packet as general function to relay
151 packet to arbitrary destination. This deprecates functions
152 like _send_private_message_key, _relay_notify etc. Affected
153 file is silcd/packet_send.[ch].
155 Removed silc_server_send_key_agreement,
156 silc_server_send_private_message_key and
157 silc_server_packet_relay_notify functions from the file
158 silcd/packet_send.[ch].
162 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
163 server. Affected file silcd/packet_receive.[ch].
165 * Implemented the KILL command to the client. Implemented the
166 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
167 Affected files lib/silcclient/command[_reply].c and
168 lib/silcclient/client_notify.c. Implemented the KILL notify
169 printing in the user inteface.
171 * Fixed a lot silc_parse_nick memory leaks from the client
172 library in the file lib/silcclient/command.c.
174 * Changed the silc_server_send_notify_on_channels's `sender'
175 argument from SilcSocketConnection to SilcClientEntry to
176 check the sender as entry and not as connection object and not
177 to send to the client provided as argument. The affected file
178 is silcd/packet_send.[ch].
180 * The notify packets that are destined directly to the client used
181 to not to be processed by the server. Now changed that and the
182 server processes all notify packets. After relaying the packet
183 to the client the notify packet is processed in the server.
185 * The silc_server_free_client_data now checks whether there is
186 pending outgoing traffic for the client and purges the data to
187 the network before removing the client entry.
189 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
191 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
192 an client is killed from the SILC Network. Updated the protocol
195 Added new function silc_server_send_notify_killed to the
196 silcd/packet_send.[ch].
198 * Added function silc_server_packet_relay_notify to relay notify
199 packets that are destined directly to a client. In this case
200 the server does not process the notify packets but merely relays
201 it to the client. Affected file silcd/packet_send.[ch].
203 Added also silc_server_packet_process_relay_notify to check
204 whereto relay the notify. Affected file is
205 silcd/packet_receive.[ch].
207 * Implemented the KILL command to the server.
211 * Added the backup schema desgined last fall to the protocol
212 specs for everyone to see. The specification is in the
213 *-spec-xx.txt draft and the packet type definitions for the
214 backup routers is in *-pp-xx.txt draft. Thusly, added also
215 new packet type SILC_PACKET_CELL_ROUTERS.
217 * A big security problem in the implementation discovered. The
218 signoff of an client did not cause new channel key generation
219 which it of course should've done. The channel keys must be
220 always re-generated when client leaves (or signoffs) the channel.
221 The silc_server_remove_from_channels funtion now handles
222 the channel key re-generation.
224 * Added `sender' argument to the silc_server_send_notify_on_channels
225 to not to send the client provided as argument. Affected file
226 silcd/packet_send.[ch].
228 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
230 * Implemented OPER and SILCOPER commands into the server and
233 * Added silc_auth_verify and silc_auth_verify_data to verify
234 the authentication directly from the authentication payload.
235 It supports verifying both passphrase and public key based
236 authentication. Affected file lib/silccore/silcauth.[ch].
238 * Added `hash' field to the SilcIDListData structure. It is the
239 hash negotiated in the SKE protocol. Affected file is
242 * Slight redesigning of the SilcAuthPayload handling routines.
243 Do not send SilcPKCS but SilcPublicKey as argument.
245 * Implemented the public key authentication support to the
246 serverconfig. The public key is loaded fromthe provided path
247 and saved as authentication data to void * pointer. Thus,
248 changed the unsigned char *auth_data to void *auth_data;
250 * Fixed SHUTDOWN command to send the reply before the server
251 is shutdown. :) Affected file silcd/command.c.
253 * Fixed fatal bug in CONNECT command. The hostname was invalid
254 memory and server crashed. Affected file silcd/command.c.
256 * Fixed fatal bug in CLOSE command. The server_entry became
257 invalid but was referenced later in the command. Affected file
260 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
262 * Fixed fatal bug in failure packet handling. Server ignored
263 the failure and thus crashed when it came.
267 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
269 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
270 that the command may be executed only once in (about) 2 seconds.
271 The old SILC_CF_LAG flag is same but allows command bursts up
272 to five before limiting.
274 Added the support for CF_LAG and CF_LAG_STRICT flags to the
275 server code. Various commands now includes the CF_LAG_STRICT
276 flag to disallow any kind of miss-use of the command.
278 * Fixed the silc_buffer_unformat to not to allocate any data
279 if the length of the data is zero. It used to allocate the
280 length + 1. Affected file lib/silcutil/silcbuffmt.c.
282 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
284 * Changed the format of AdminConnection configuration section
285 in the server. Added username of the admin to the format.
286 Affected files silcd/serverconfig.[ch].
288 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
289 to return admin configuration data by host, username and/or
292 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
294 * Implemented WHOWAS command to the server. Added the functions:
296 silc_server_command_whowas_parse,
297 silc_server_command_whowas_send_reply,
298 silc_server_command_whowas_from_client and
299 silc_server_command_whowas_from_server
301 * Added <Client ID> argument to the WHOWAS command reply. Updated
302 the protocol specs accordingly.
304 * Implemented WHOWAS command and command_reply to the client
307 Implemented the WHOWAS printing on the user interface.
309 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
311 * Added new argument to the WHOWAS command reply, the real name.
312 It is an optional argument. Updated the protocol specs.
314 * Added SilcIDCacheDestructor callback that is registered when
315 the SilcIDCache is allocated. The callback is called when
316 an cache entry in the ID Cache expires, or is purged from the
317 cache. Added into lib/silccore/idcache.[ch].
319 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
320 to destruct the client entries when the cache entry expires.
321 Other ID Cache's in server and in the client library ignores
324 * If the ID Cache entry's `expire' field is zero then the entry
325 never expires. Added boolean `expire' argument to the
326 silc_idcache_add function in the lib/silccore/idcache.[ch].
327 If it is TRUE the default expiry value is used.
329 * Added silc_server_free_client_data_timeout that is registered
330 when client disconnects. By default for 5 minutes we preserve
331 the client entry for history - for WHOWAS command.
333 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
335 * Added support to the server to enforce that commands are not
336 executed more than once in 2 seconds. If server receives
337 commands from client more frequently, timeout is registered
338 to process the commands. Affected file silcd/command.c.
339 Added new function silc_server_command_process_timeout.
341 * Changed NICK_NOTIFY handling in client library to check that
342 if the client's nickname was changed, so there is no need to
343 resolve anything from the server.
345 * Removed error printing from the WHOIS and IDENTIFY commands.
346 If error occurs then it is ignored silently in the client library.
347 The application, however, may map the received error to
348 human readable error string. The application currently maps
349 the NO_SUCH_NICKNAME error to string.
351 * Made the command status message public to the application. Moved
352 them from lib/silcclient/command_reply.c to
353 lib/silcclient/command_reply.h. The application can map the
354 received command status to the string with the
355 silc_client_command_status_message function.
357 * Added check to the server to check that client's ID is same
358 as the Source ID in the packet the client sent. They must
361 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
363 * Added dist-bzip hook to the Makefile.am to make bzip2
364 compressed distributions.
366 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
368 * Server now enforces the maximum length for the nickname and
369 the channel as protocol specification dictates. 128 bytes for
370 nickname and 256 bytes for channel name.
372 * Moved the WHOIS printing to the application. The client libary
373 does not print out the WHOIS information anymore, the application
374 must do it. Renamed silc_client_command_reply_whois_print to
375 the silc_client_command_reply_whois_save.
377 The client's idle time is also sent to the application now, and
378 the idle is shown on screen.
380 * Added silc_client_command_reply_identify_save to save the
381 received IDENTIFY entries.
383 * Do not check for channel private keys in message sending and
384 reception if the channel does not have the PRIVKEY mode set.
385 Affected file lib/silclient/client_channel.c.
387 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
389 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
390 just surfaced after chaning the JOIN procedure.
392 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
394 * Added silc_client_get_clients_by_list to get client entries
395 from Client ID list, that is returned for example by JOIN
396 and USERS command replies. The application should use this
397 function for example when JOIN command reply is received to
398 resolve the clients already on the channel (library does not
399 do that anymore as USERS command reply is not used in the JOIN
400 procedure anymore). Affected files lib/silcclient/silcapi.h and
401 lib/silcclient/idlist.c.
403 * JOIN command reply and USERS command reply returns now SilcBuffer
404 pointers instead of unsigned char pointers when returning
405 the client list and mode list.
407 * Added <Client ID> argument to the JOIN command reply, mainly
408 for the server to identify for which client the command was
409 originally sent. Updated protocol specs accordingly.
411 * Added SilcDlist private_key pointer to the SilcChannelEntry
412 in the client to support the channel private keys. Affected
413 file is lib/silcclient/idlist.h.
415 * Added SilcChannelPrivateKey argument to the function
416 silc_client_send_channel_message so that application can choose
417 to use specific private ke if it wants to. If it is not provided,
418 the normal channel key is used, unless private keys are set.
419 In this case the first (key that was added first) is used
420 as the encryption key.
422 * Implemented the support for channel private key handling.
423 Implemented the following functions:
425 silc_client_add_channel_private_key,
426 silc_client_del_channel_private_keys,
427 silc_client_del_channel_private_key,
428 silc_client_list_channel_private_keys and
429 silc_client_free_channel_private_keys
431 Affected file lib/silcclient/client_channel.c.
433 * Added the support for the private keys in the channel message
434 sending and encryption and in the message reception and
435 decryption. Affected funtions are
436 silc_client_send_channel_message and silc_client_channel_message.
438 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
440 * Added SKE's key verify callback to the client library's
441 KE protocol context. Affected files lib/silcclient/protocol.[ch].
443 * Removed the statement that server (or router) must send USERS
444 command reply when joining to the channel so that the client
445 knows who are on the channel. Instead, the client list and
446 client's mode list is now sent in the JOIN command reply to the
447 client who joined channel. This is better solution.
449 * Added function silc_server_get_users_on_channel and function
450 silc_server_save_users_on_channel to the silcd/server.[ch].
452 * Removed function silc_server_command_send_users from the
455 * Do not show topic on the client library anymore. The topic is
456 sent in the command reply notify to the application and the
457 application must show the topic now.
459 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
461 * Added client searching by nickname hash into the IDENTIFY and
462 WHOIS commands in the server as they were clearly missing from
463 them. Affected file is silcd/command.c.
465 * Fixed a bug in private message receiving in the client library.
466 The remote ID was freed and it wasn't supposed, now it is
469 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
471 * Minor fix to the channel payload; allocate the data area, as it
472 needs to be of specific length.
474 * If the key agreement port is zero then the operating
475 system will define the bound port. Affected files are
476 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
478 * Added new function silc_channel_payload_decrypt into the file
479 lib/silccore/silcchannel.[ch].
481 * Moved the channel message etc, check from silc_packet_decrypt
482 to applications. The library calls now a generic
483 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
484 when the packet is either normal or special. This was done to
485 allow more wide range of checking that was not allowed when
486 the code was in library. Now applications can do virtually any
487 checks to the packet and return to the library the decision how
488 the packet should be processed. Affected files are
489 lib/silccore/silcpacket.[ch].
491 Added silc_server_packet_decrypt_check to the server and
492 silc_client_packet_decrypt_check to the client library.
494 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
495 to send with specified source and destination information.
497 * Channel message delivery between routers was broken after the
498 channel key distribution was fixed earlier. The channel key
499 was used be to distributed to other routers as well which is not
500 allowed by the protocol. Now this is fixed and channel keys
501 really are cell specific and the channel message delivery between
502 routers comply with the protocol specification.
504 * Fixed various commands in server to check also the global list
505 for the channel entry and not just the local list. The affected
506 file silcd/command.c.
508 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
510 * Added assert()s to buffer formatting and unformatting routines
511 to assert (if --enable-debug) when error occurs. Affected
512 file: lib/silcutil/silcbuffmt.c.
514 * Changed to auto-reconnect to check whether the remote host is
515 router and register the re-connect timeout if it is. It used
516 to check that whether we are normal server, but router must do
517 auto-reconnect with another router as well. Affected file
520 * Removed the [<key len>] option from CMODE command as the cipher
521 name decides the key length, nowadays. See the defined ciphers
522 from the protocol specification.
524 * Added [<hmac>] option to the CMODE command to define the HMAC
525 for the channel. Added SILC_CMODE_HMAC channel mode.
527 * Added [<hmac>] option for the JOIN command so that user can
528 select which HMAC is used to compute the MACs of the channel
531 * Added Hmac field to the Channel Message Payload. The integrity
532 of plaintext channel messages are now protected by computing
533 MAC of the message and attaching the MAC to the payload. The
534 MAC is encrypted. Now, it is clear that this causes some
535 overhead to the size of the packet but rationale for this is that
536 now the receiver can verify whether the channel message decrypted
537 correctly and also when private keys are set for the channel the
538 receiver can decrypt the packet with several keys and check from
539 the MAC which key decrypted the message correctly.
541 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
542 lib/silccrypt/silccipher.[ch].
544 * Added silc_hash_len to return the digest length into the
545 lib/silcrypt/silchash.[ch].
547 * Rewrote parts of Silc Channel Payload interface in the
548 lib/silccore/silcchannel.[ch]. The encode function now also
549 encrypts the packet and parse function decrypts it.
551 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
553 * Fixed a minor formatting bug in the SKE's key material processing.
554 It actually might have processed the keys wrong way resulting
557 * Redefined the mandatory HMAC algorithms and added new algorithms.
558 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
559 and hmac-md5 truncated to 96 bits. The mandatory is now
560 hmac-sha1-96. Rest are optional (including the one that used
561 to be mandatory). Rationale for this is that the truncated HMAC
562 length is sufficient from security point of view and can actually
563 make the attack against the HMAC harder. Also, the truncated
564 HMAC causes less overhead to the packets. See the RFC2104 for
567 * Added new [hmac] configuration section. The SKE used to use
568 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
569 is of course wrong. The official names that must be proposed in
570 the SKE are the ones defined in the protocol specification
571 (hmac-sha1-96 for example). The user can configure any hmac
572 using any hash function configured in the [hash] section. At
573 least, the mandatory must be configured.
575 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
577 * Added HMAC list to the SKE proposal list. It has now both
578 hash algorithm list and HMAC list. This makes the protocol
579 incompatible with previous versions. The SKE now seems to work
580 the way it is supposed to work, for the first time actually.
582 * Defined plain Hash algorithms to the protocol specification.
585 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
587 * Implemented support for key agreement packets into the server.
588 Added functions silc_server_key_agreement and
589 silc_server_send_key_agreement. Other than these functions,
590 server has nothing to do with this packet.
592 * Added support for private message key packets into the server.
593 Added functions silc_server_private_message_key and
594 silc_server_send_private_message_key.
598 * Changed the silc_[client|server]_protocol_ke_set_keys to be
599 called in the protocol's final callback instead in the END
600 protocol state. This makes a little more sense and in the same
601 time in client we can use the same protocol routines for normal
602 key exchange and to key agreement packet handling as well.
604 * Added to both client's and server's KE protocol context the
605 SilcSKEKeyMaterial pointer to save the key material. We will
606 bring the key material to the protocol's final callback by doing
607 this. The final callback must free the key material.
609 * Added SKE's packet_send callback into client's KE protocol
610 context so that the caller can choose what packet sending function
611 is used. This way we can use different packet sending when
612 doing normal SKE when doing key agreement packet handling (in
613 the key agreement packet handling we do not want to encrypt
616 * Implemented the responder side of the key agreement routines
617 in the client. The client can now bind to specified port and
618 accept incoming key negotiation. The key material is passed
619 to the application after the protocol is over.
621 * Implemented the processing of incoming Key Agreement packet
622 in the client. Added function silc_client_key_agreement to
625 * Implemented the intiator side of the key agreement routines
626 in the client. The client can now initiate key agreement with
627 another remote client. The key material is passed to the
628 application after the protocol is over.
630 * Created client_keyagr.c to include all the key agreement
633 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
634 SILC_TASK_CALLBACK except that it is not static.
636 * Created client_notify.c and moved the Notify packet handling
637 from the client.[ch] into that file.
639 * Created client_prvmsg.c and moved all private message and
640 private message key routines from the client.[ch] into that file.
642 * Create client_channel.c and moved all channel message and
643 channel private key routines from the client.[ch] into that file.
645 * Changed silc_client_get_client_by_id_resolve to resolve with
646 WHOIS command instead of IDENTIFY command, in the file
647 lib/silclient/idlist.c.
649 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
651 * Implemented the SKE's responder side to the Client library.
653 * When FAILURE is received to the protocol do not trust it
654 blindly. Register a timeout to wait whether the remote closes
655 the connection as it should do it, only after that process the
656 actual failure. This was changed to both client and server.
658 * Added client_internal.h to include some of the structures
659 there instead of client.h in lib/silcclient/.
661 * Added function silc_task_unregister_by_callback to unregister
662 timeouts by the callback function.
664 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
666 * Some "Incomplete WHOIS info" errors has been appearing on the
667 log files. Took away the entry->userinfo check from WHOIS
668 reply sending. The entry->userinfo is now " " if client did not
669 provide one. I thought this was fixed earlier but something
670 is wrong still. Let's see if the error still appears.
672 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
674 * Fixed a minor bug in the login when the channel key is
675 re-generated in the server. It used to generate the key in
676 wrong order and thus caused problems in the channel traffic.
678 * Fixed a minor bug in channel key distsribution after
679 KICK command. The key was not sent to the router even though
682 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
684 * Added silc_ske_process_key_material_data as generic routine
685 to process any key material as the SILC protocol dictates. The
686 function is used by the actual SKE library but can be used by
687 applications as well. This relates to the private message keys
688 and the channel private keys since they must be processed the
689 same way the normal SILC session keys. The protocol dictates
690 this. Affected files: lib/silcske/silcske.[ch].
692 Added also silc_ske_free_key_material to free the
693 SilcSKEKeyMaterial structure.
695 * Defined silc_cipher_set_key function to set the key for
696 cipher without using the object's method function. The affected
697 files: lib/silccrypt/silccipher.[ch].
699 * Implemented silc silc_client_add_private_message_key,
700 silc_client_add_private_message_key_ske,
701 silc_client_del_private_message_key,
702 silc_client_list_private_message_keys and
703 silc_client_free_private_message_keys functions in the
706 Added functions silc_client_send_private_message_key to send
707 the Private Message Key payload and silc_client_private_message_key
708 to handle incoming Private Message Key payload.
710 * Added Cipher field to the Private Message Key payload to set
711 the cipher to be used. If ignored, the default cipher defined
712 in the SILC protocol (aes-256-cbc) is used.
714 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
716 * Removed lib/silcclient/ops.h file.
718 Redefined parts of the SILC Client Library API. Created new
719 file silcapi.h that deprecates the ops.h file and defines the
720 published Client Library API. Defined also private message key
721 API and channel private key API into the file.
723 This is the file that the application must include from the
724 SILC Client Library. Other files need not be included by
725 the application anymore.
727 * Added new key_agreement client operation callback and also
728 defined the Key Agreement library API for the application.
730 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
732 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
733 is used by clients to request key negotiation between another
734 client in the SILC network. If the negotiation is started it
735 is performed using the SKE protocol. The result of the
736 negotiation, the secret key material, can be used for example
737 as private message key.
739 Implemented the Key Agreement payload into the files
740 lib/silccore/silauth.[ch].
742 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
744 * Redefined ciphers for the SILC protocol. Added some new ciphers
745 and defined the key lengths for the algorithms. Changed the
746 code accordingly. The default key length is now 256 bits.
748 * Fixed SKE key distribution function silc_ske_process_key_material
749 when the key length is more than 128 bits. The default key
750 length in SILC is now 256 bits.
752 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
753 to indicate unsupported algorithm.
755 * Renamed rijndael.c to aes.c and all functions as well.
757 * Fixed a long standing channel key setting bug in client library.
758 Weird that it has never surfaced before.
760 * Fixed bug in channel deletion. If the entire channel is removed
761 then it must also delete the references of the channel entry
762 from the client's channel list as the client's channel entry and
763 the channel's client entry share same memory.
765 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
767 * Implemented CONNECT and SHUTDOWN commands in the client.
769 * Implemented CLOSE command to the client.
771 * Added the function silc_idlist_find_server_by_name into the
772 files silcd/idlist.[ch].
774 Added the function silc_idlist_find_server_by_conn into the
775 files silcd/idlist.[ch].
777 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
779 * DIE command was renamed to SHUTDOWN. Updated the both code
782 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
783 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
785 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
788 * Added function silc_server_create_connection function to create
789 connection to remote router. My server implementation actually
790 does not allow router to connect to normal server (it expects
791 that normal server always initiates the connection to the router)
792 so the CONNECT command is only good for connecting to another
795 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
797 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
798 or some other client was kicked from the channel.
800 Implemented the handling of the notify type to both client
803 Implemented silc_server_send_notify_kicked to send the KICKED
804 notify. It is used to send it to the server's primary router.
806 * Implemented the KICK command into server and client.
808 * Added `query' argument to the silc_idlist_get_client function
809 to indicate whether to query the client from server or not if
812 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
813 to indicate that the client is not channel founder.
817 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
819 * Removed the rng context from SilcPacketContext structure and
820 changed that the packet routine uses the Global RNG API.
822 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
824 * Added support for quit message that client can "leave" on the
825 channel when it quits the SILC. It is ditributed inside the
826 SILC_NOTIFY_TYPE_SIGNOFF notify type.
828 Added silc_server_free_client_data that will take the
829 signoff message as argument.
831 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
833 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
835 * Updated parts of the protocol specification to keep it up
838 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
840 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
841 payloads in one packet.
843 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
844 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
845 use now the new List flag.
847 * Also deprecated the following packet types: REPLACE_ID,
848 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
850 * Added list support for Notify packet in server.
852 * Added silc_server_send_notify_channel_change to send the
853 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
854 the silc_server_send_replace_id.
856 * Added silc_server_send_notify_nick_change to send the
857 NICK_CHANGE notify type. Deprecates the function
858 silc_server_send_replace_id.
860 * Added silc_server_send_notify_join to send the JOIN notify type.
861 Deprecates the function silc_server_send_new_channel_user.
863 * Added silc_server_send_notify_leave to send LEAVE notify type.
864 Deprecates the function silc_server_send_remove_channel_user.
866 * Added silc_server_send_notify_cmode and
867 silc_server_send_notify_cumode to send CMODE and CUMODE notify
868 types. Deprecates the silc_server_send_set_mode function.
870 * Added SERVER_SIGNOFF notify type to indicate that server has
871 quit. This means that all clients on the channel from that
872 server will drop. This can be also used when netsplit happens.
874 Deprecated REMOVE_ID packet type since it is not needed anymore
877 Added silc_server_send_notify_server_signoff to send the
878 SERVER_SIGNOFF notify type. Deprecates the function
879 silc_server_send_remove_id.
881 Added also silc_server_send_notify_signoff to send the
884 * Employed the PKCS #1. It is the mandatory way to do RSA in the
885 SILC protocol from this day on. Changed the protocol
886 specification as well.
888 * Added silc_server_send_notify_topic_set to send TOPIC_SET
889 notify type. It is used between routers to notify about
890 topic changes on a channel.
892 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
895 * Partly updated the protocol specification to comply with the
896 changes now made. It is still though a bit outdated.
898 * The JOIN notify type now takes one extra argument <Channel ID>.
899 The packet used to be destined to the channel but now the
900 JOIN type may be sent as list thus it is impossible to
901 destine it to any specific channel. By adding this argument
902 it is again possible.
904 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
906 * Added CREDITS file. The CHANGES and CREDITS file will appear
907 in the distribution as well.
909 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
911 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
912 types in the server's silcd/packet_receive.c.
914 * Implemented CMODE and CUMODE to work in router environment.
916 * Fixed minor encoding and decoding buglet from the
917 lib/silccore/silcmode.c.
919 * Fixed buffer overflow from lib/silcclient/command.c in USERS
922 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
924 * Changed all SilcConfigServer* and silc_config_server* to
925 SilcServerConfig* and silc_server_config*, respectively.
928 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
930 * Associated the ID (client or server ID) to the Authentication
931 Payload to avoid any possibility of forging. Updated the
932 protocol specification and the code accordingly.
934 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
936 * The RSA key length is now save to the RsaKey context in the
937 key generation process in lib/silccrypt/rsa.c. The key length
938 is now used to figure out the maximum size of the block allowed
939 to be encrypted/signed.
941 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
942 is equivalent to the silc_mp_mp2bin but does not allocate any
945 * Changed silc_mp_mp2bin API to take length argument. If it is
946 non-zero then the buffer is allocated that large. If zero, then
947 the size is approximated using silc_mp_sizeinbase, which however
950 * Created Global RNG API which is global RNG that application can
951 initialize. After initializing, any routine anywhere in the
952 code (including library) can use RNG without allocating a new
953 RNG object. This was done to allow this sort of use of the
954 RNG in code that has no chance to allocate RNG object. All
955 applications currently allocate this and many routines in the
956 library use this. Affected file lib/silccrypt/silcrng.[ch].
958 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
959 it to use the Global RNG API.
961 * Defined Authentication Payload into protocol specification that
962 is used during SILC session to authenticate entities. It is
963 used for example by client to authenticate itself to the server
964 to obtain server operator privileges.
966 Implemented this payload into the lib/silccore/silcauth.[ch].
967 Implemented also routines for public key based authentication
968 as the new protocol specification dictates.
970 Moved definitions of different authentication methods from
971 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
973 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
974 silc_pkcs_verify and silc_pkcs_sign_with_hash and
975 silc_pkcs_verify_with_hash functions into the file
976 lib/silccrypt/silcpkcs.[ch].
978 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
980 * The client entry's userinfo pointer must be always valid.
981 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
982 will fail since it requires the userinfo. Now, the userinfo
983 is allocated as "" if actual userinfo does not exist. Actually,
984 it must exist and it is totally Ok to drop client connections
985 that does not announce the userinfo. However, we will make
986 this workaround for now.
988 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
989 to return the remote port by socket.
991 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
993 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
994 SILC_SERVER_PENDING_EXEC and added an new macro
995 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
996 data or when error occurs while processing the pending command.
998 Added new argument `destructor' into silc_server_command_pending
999 and to the SilcServerCommandPending object. This destructor is
1000 now called after calling the pending callback or if error occurs
1001 immediately. If error occurs the actual pending callback won't
1002 be called at all - only the destructor. The destructor may be
1003 NULL if destructor is not needed.
1005 All this applies for client library code as well. Similar
1006 changes were made there as well for the pending commands.
1008 In the client, the application must now allocate the
1009 SilcClientCommandContext with the silc_client_command_alloc
1012 * Added reference counter to the SilcServerCommandContext. Added
1013 function silc_server_command_alloc and silc_server_command_dup
1016 Same type of functions added to the client library for the same
1019 * Removed the cmd_ident from IDListData away since it is now
1020 global for all connections. It is the command identifier used
1021 in command sending and with pending commands. The affected file
1024 * Added reference counter to the SilcSocketConnection objecet to
1025 indicate the usage count of the object. The object won't be
1026 freed untill the reference counter hits zero. Currently only
1027 server uses this, and client ignores it. The client must be
1028 set to use this too later. The affected files are
1029 lib/silccore/silcsockconn.[ch]. Added also the function
1030 silc_socket_dup to increase the reference counter.
1032 This was mainly added because it is possible that the socket
1033 is removed underneath of pending command or other async
1034 operation. Now it won't be free'd and proper DISCONNECTING
1035 flags, etc. can be set to avoid sending data to connection that
1036 is not valid anymore.
1038 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1039 the connection. After that it sets SILC_SET_DISCONNECTED.
1040 It is, however, possible that the socket data is not still freed.
1041 The silc_server_packet_process now checks that data is not
1042 read or written to connection that is DISCONNECTED. The socket
1043 get's freed when the reference counter hits zero.
1045 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1047 * Changed the client operation API: channel_message operation's
1048 `sender' is now the client entry of the sender, not the nickname
1049 and the `channel' is the channel entry, not the channel name.
1051 In the private_message operation the `sender' is now also the
1052 client entry of the sender not the nickname.
1054 Affected file is lib/silcclient/ops.h and all applications
1055 using the client operations.
1057 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1059 * Moved the calling of ops->connect() from connect_to_server_final
1060 into receive_new_id functin since that is the point when the
1061 client is actually allowed to send traffic to network. The
1062 affected file is lib/silcclient/client.c.
1064 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1066 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1067 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1068 (if needs broadcasting) instead of broadcasting the packets one
1069 by one which would make a burst in the network traffic.
1071 * Added `broadcast' argument to the functions in silcd/server.[ch]
1072 silc_server_create_new_channel[_with_id] to indicate whether
1073 to send New Channel packet to primary router.
1075 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1077 * Added new function into the silcd/server.[ch] files:
1078 silc_server_create_new_channel_with_id to create new channel with
1079 already existing Channel ID.
1081 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1082 lib/silccore/silcpacket.h. This packet is used t send list of
1083 Set Mode payloads inside one packet. Server uses this to set
1084 the modes for the channels and clients on those channels, that it
1085 announced to the router when it connected to it. The protocol
1086 specification has been updated accordingly.
1088 * The silc_server_new_channel did not handle the packet coming
1089 from normal server as it normally does not send that. However,
1090 when it announces its channels it does send it. Implemented
1091 the support for that.
1093 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1094 into the file lib/silccore/id.h.
1096 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1098 * Fixed memory leaks in the functions silc_idlist_del_client,
1099 silc_idlist_del_channel and silc_idlist_del_server in the file
1100 silcd/idlist.c. All of those leaked like a sieve.
1102 * Fixed some small memory leaks in the client's function
1103 silc_client_notify_by_server.
1105 * Added functions into silcd/server.c: silc_server_announce_clients,
1106 silc_server_announce_channels and silc_server_announce_server.
1107 These functions are used by normal and router server to announce
1108 to its primary router about clients, channels and servers (when
1109 router) that we own. This is done after we've connected to the
1112 These functions effectively implements the following packet types:
1113 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1114 and SILC_PACKET_NEW_ID_LIST.
1116 * Added new functions into the silcd/packet_receive.[ch]:
1117 silc_server_new_id_list, silc_server_new_channel_list and
1118 silc_server_new_channel_user_list to handle the incoming
1119 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1121 * Added support of changing Channel ID in the function
1122 silc_server_replace_id. If the server that announces a channel
1123 to the router already exists in the router (with same name but
1124 with different Channel ID), router is responsible to send
1125 Replace ID packet to the server and force the server to change
1126 the Channel ID to the one router has.
1128 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1129 client that the Channel ID has been changed by the router. The
1130 normal server sends this to the client. Client must start using
1131 the new Channel ID as the channel's ID.
1133 Implemented handling of this new type into lib/silcclient/client.c
1134 into the function silc_client_notify_by_server.
1136 * Added new function silc_idlist_replace_channel_id into the files
1137 silcd/idlist.[ch] to replace the Channel ID.
1139 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1141 * Call silc_server_command_identify_check always when processing
1142 the IDENTIFY command in silcd/command.c
1144 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1146 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1147 send keepalive packets. The packet can be sent by clients,
1148 servers and routers.
1150 Added function silc_socket_set_heartbeat into the file
1151 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1152 If not set, the heartbeat is not performed. The actual
1153 heartbeat is implemented in the low level socket connection
1154 library. However, application is responsible of actually
1157 Added silc_server_send_heartbeat to send the actual heartbeat
1158 packet into silcd/packet_send.[ch]. Server now performs
1159 keepalive with all connections.
1161 * Added silc_task_get_first function into lib/silcutil/silctask.c
1162 to return the timeout task with shortest timeout. There was a bug
1163 in task unregistration that caused problems. TODO has been
1164 updated to include that task system must be rewritten.
1166 * The client library will now resolve the client information when
1167 receiving JOIN notify from server for client that we know but
1168 have incomplete information.
1170 * Rewrote parts of silc_server_remove_from_channels and
1171 silc_server_remove_from_one_channel as they did not remove the
1172 channel in some circumstances even though they should've.
1174 * Encryption problem encountered in server:
1176 The LEAVE command used to send the Channel Key packet to the
1177 router immediately after generating it. However, the code
1178 had earlier sent Remove Channel user packet but not immediately,
1179 ie. it was put to queue. The order of packets in the router
1180 was that Channel Key packet was first and Remove Channel User
1181 packet was second, even though they were encrypted in the
1182 reverse order. For this reason, MAC check failed. Now, this
1183 is fixed by not sending the Channel Key packet immediately but
1184 putting it to queue. However, this is more fundamental problem:
1185 packets that are in queue should actually not be encrypted
1186 because packets that are sent immediately gets encrypted
1187 actually with wrong IV (and thus MAC check fails). So, packets
1188 that are in queue should be encrypted when they are sent to
1189 the wire and not when they put to the queue.
1191 However, the problem is that the current system has not been
1192 designed to work that way. Instead, the packet is encrypted
1193 as soon as possible and left to the queue. The queue is then
1194 just purged into wire. There won't be any fixes for this
1195 any time soon. So, the current semantic for packet sending
1198 o If you send packet to remote host and do not force the send
1199 (the packet will be in queue) then all subsequent packets to the
1200 same remote host must also be put to the queue. Only after the
1201 queue has been purged is it safe again to force the packet
1204 o If you send all packets immediately then it safe to send
1205 any of subsequent packets through the queue, however, after
1206 the first packet is put to queue then any subsequent packets
1207 must also be put to the queue.
1209 Follow these rules and everything works fine.
1211 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Added new function silc_server_remove_clients_by_server to
1214 remove all client entries from ID list when the server connection
1215 is lost. In this case it is also important to invalidate all
1216 client entires as they hold the invalid server entry. This
1217 fixes fatal bug when server has lost connection and will reconnect
1220 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1222 * Made some sanity checks to silc_server_daemonise like to check
1223 whether the requested user and group actually exists.
1225 * Added sanity check to SKE's silc_ske_responder_finish to check
1226 that the public and private key actually is valid.
1228 * Invalidate the client's nickname when receiving Replace ID
1229 packet and the Client ID is being replaced. This means that the
1230 server will query the nickname if someone needs it (client)
1233 * Sort the ID Cache in client library when the ID Cache data
1234 has changed (needs sorting).
1236 * Do not allow for SILC client to create several connections to
1237 several servers. The client does not support windows right now
1238 and generating multiple connections causes weird behaviour.
1240 Irssi-silc client does support windows and can handle several
1241 connections without problems, see: www.irssi.org and SILC plugin.
1243 * Fixed some places where client was added to the IDList. The
1244 rule of thumb is following (in order to get everything right):
1245 If the client is directly connected local client then the
1246 `connection' argument must be set and `router' argument must be
1247 NULL to silc_idlist_add_client function. If the client is not
1248 directly connected client then the `router' argument must
1249 bet set and the `connection' argument must be NULL to the
1250 silc_idlist_add_client function.
1252 * The funtion silc_server_packet_send_local_channel actually did
1253 not check whether the client was locally connected or not. It
1254 does that now. Fixed a bug related to LEAVE command.
1256 * Fixed Remove Channel User payload parsing bug in server's
1257 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1259 * The server's silc_server_save_channel_key now checks also the
1260 global ID list for the channel as it might not be in the local
1261 list. Fixed a bug related to LEAVE command.
1263 * Is this the end of the [<unknown>] buglet that has been lurking
1264 around for a long time? A little for loop fix in server's
1265 silc_server_command_whois_parse that is used by both IDENTIFY
1266 and WHOIS command. At least, this was a clear bug and a cause
1267 of one type of [<unknown>] buglet.
1269 * WHOIS and IDENTIFY commands call the function
1270 silc_server_command_[whois/identify]_check function even if
1271 we are not router server.
1273 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1275 * Added --with-gmp configuration option. If set the GMP
1276 is always compiled in the SILC source tree. If not set then
1277 it is checked whether the system has the GMP3 installed. If
1278 it has then the GMP won't be compiled (the system's headers
1279 and library is used), if it doesn't have it then the GMP is
1280 compiled in the SILC source tree.
1282 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1284 * Changed RSA private exponent generation to what PKCS #1
1285 suggests. We try to find the smallest possible d by doing
1286 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1287 not security fix but optimization.
1289 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1291 * Added new config entry [Identity] to fork the server and run
1292 it as specific user and group. A patch from Bostik.
1294 * Imported Dotconf configuration library into lib/dotconf.
1295 This will be used to create the SILC configuration files later.
1296 It will appear in the distsribution after this commit.
1298 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1300 * A big code auditing weekend happening. Auditing code for
1301 obvious mistakes, bugs and errors. Also, removing any code
1304 Removed files for being obsolete:
1306 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1307 inline in the file lib/silcutil/silcbuffer.h)
1309 o lib/silcutil/silcbufutil.c (the header has inline versions)
1311 Changed code to fix possible error conditions:
1313 o The buffer formatting routines now check that the destination
1314 buffer really has enough space to add the data. This applies for
1315 both buffer formatting and unformatting
1316 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1317 unformatting was changed to accomodate following rules:
1318 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1319 sent to the function while XXX_*STRING will not allocate or copy
1320 the data into the buffer. Instead it sets the pointer from the
1321 buffer into the pointer sent as argument (XXX_*STRING used to
1322 require that the pointer must be allocated already). This change
1323 makes this whole thing a bit more consistent and more optimized
1324 (note that the data returned in the unformatting with XXX_*STRING
1325 must not be freed now). The routines return now -1 on error.
1327 o Tried to find all code that use buffer_format and buffer_unformat
1328 and added return value checking to prevent formatting and
1329 especially unformatting errors and possible subsequent fatal
1332 o Changed ske->x and ske->KEY to mallocated pointers in
1333 lib/silcske/silcske.h. Fixed possible data and memory leak.
1335 o Added return value checking to all *_parse* functions. Fixed
1336 many memory leaks as well.
1338 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1339 so that buffer overflows would not happen. All code now also
1340 checks the return value as it can fail.
1342 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1344 * Added reconnection support to server if the normal server looses
1345 its connection to the router (for example if router is rebooted).
1346 The server performs normal reconnection strategy implemented
1347 to the server. Affected file silcd/server.c.
1349 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1351 * Added new packet type SILC_PACKET_SET_MODE that is used to
1352 distribute the information about changed modes (for clients,
1353 channels and clients channel modes) to all routers in the
1354 network. Updated the protocol specification accordingly.
1356 Added functions into silcd/packet_send.c and
1357 silcd/packet_receive.c: silc_server_send_set_mode,
1358 silc_server_set_mode.
1360 Added new files silcmode.[ch] into lib/silccore that implements
1361 the encoding and decoding of Set Mode Payload. Added new type
1362 SilcSetModePayload. Moved the definitions of different modes
1363 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1365 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1367 * Oops, a little mistake in server's connection authentication
1368 protocol. The protocol is not ended with FAILURE but with
1369 SUCCESS if the authentication is Ok. :) Affected file is
1372 * Implemented NICK_CHANGE notify handling in server in the file
1373 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1374 the local clients on the channel. After the changing nickname
1375 in router environment snhould work and the [<unknown>] nickname
1376 should appear no more.
1378 The silc_server_replace_id function that receives the Replace ID
1379 payload now sends the NICK_CHANGE notify type also in the file
1380 silcd/packet_receive.c
1382 * Changed WHOIS and IDENTIFY command to support the maximum amount
1383 of arguments defined in protocol specs (3328 arguments). This
1384 fixed a bug that caused problems when there were more than three
1387 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1389 * Added extra parameter, command identifier, to the
1390 silc_client_send_command so that explicit command identifier
1393 Changed that ID list routines uses specific command identifier
1394 when sending WHOIS/IDENTIFY requests to the server so that they
1395 can be identified when the reply comes back.
1397 Affected files lib/silcclient/command.[ch],
1398 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1400 * Added `sender' argument to silc_server_packet_send_to_channel
1401 to indicaet the sender who originally sent the packet to us
1402 that we are now re-sending. Ignored if NULL. Affected file
1403 silcd/packet_send.[ch].
1405 * Added some server statistics support in silcd/server_internal.h
1406 SilcServerStatistics structure and around the server code. Also
1407 send some nice statistics information when client is connecting
1410 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1412 * Fixed channel ID decoding in server's JOIN command reply in
1413 silcd/command_reply.c
1415 * Fixed braodcasting of replace ID payload to not to send it if
1416 we are standalone server in silcd/packet_receive.c.
1418 * Fixed all channel message sending routines to not to send
1419 packets to clients that has router set, since they are routed
1420 separately in the same function earlier. Affects file
1421 silcd/packet_send.c and all channel packet sending functions.
1423 * In USERS reply, res_argv[i] are not allocated, the table
1424 is allocated. Thus changed that free the table, not its
1427 * In server's whois_check and identify_check if the client is
1428 locally connected do not send any WHOIS commands - they are not
1431 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1433 * Fixed some minor bugs in client when sending WHOIS command. The
1434 arguments was in wrong order.
1436 * Removed statis function add_to_channel from server in
1437 silcd/command.c that was previously used with the joining but
1440 * Tested USERS command in router environment successfully with two
1441 routers, two servers and two clients.
1443 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1445 * Reorganized the USERS command and command reply in client library
1446 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1447 When the command is given by user we register a pending command
1448 callback that will reprocess the command after the reply has been
1449 received from the server. When reprocessing the packet we then
1450 display the information. Thus, the USERS information is displayed
1451 now in the command callback instead of in the command reply
1452 callback. The processing of the command is same as previously
1453 when server has sent the command reply in the JOINing process.
1455 * Added to USERS command in silcd/command_reply.c to join the client,
1456 we didn't use to know about, to the channel after we've created
1457 a client entry for it. Also, for clienet we did know already still
1458 check whether it is on the channel or not and add it if not.
1460 * Removed silc_server_command_join_notify as the function and its
1463 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1465 * Changed the client's pending command handling to the same as the
1466 server's pending command handling. It is also now possible to
1467 execute command reply functions from other command reply
1468 function as the function callbacks for commands and command
1469 replies are one and same. The pending commands are not static
1470 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1471 in client connection context. Thus, pending commands are server
1472 connection specific as it is convenient.
1474 Changed the function silc_client_command_pending and
1475 silc_client_command_pending_del and added new function
1476 silc_client_command_pending_check. Removed the
1477 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1480 * Added cmd_ident, current command identifier, to the client
1481 connection context in lib/silcclient/client.h to keep track on
1482 command identifiers used in command sending. Client's command reply
1483 function handling now supports the mandatory command identifiers.
1485 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1486 funtions in client to fully support pending command callbacks.
1488 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1489 as one of the arguments to the application in the command reply
1492 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1493 before first releasing SILC but came back. Now it is removed again
1494 and should come back nomore. The FORWARDED flag was used only
1495 by the JOINing procedure by forwarding the command packet to router.
1496 Now, the JOINing procedure has been changed to more generic (due
1497 to various router environment issues) and FORWARDED is not needed
1498 anymore for anything. The protocol specification is yet to be
1501 Now, removed silc_server_packet_forward from server and the flag
1502 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1504 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1506 * Renamed NAMES command to USERS command. The NAMES was named that
1507 due to historical reasons. Now it is renamed. Also, rewrote
1508 parts of the USERS command. The nickname list is not sent anymore
1509 by the server. Only Client ID and mode lists are sent in the USERS
1510 command. Changed this also to the protocol specification.
1512 The client now resolves the names and stuff after it receives
1513 the USERS list from the server when joining to the channel.
1515 * WHOIS and IDENTIFY commands has been changed to support multiple
1516 Client ID's per command. One can now search for multiple users
1517 in the network by sending only one WHOIS or IDENTIFY command.
1518 Changed the code and the protocol specifications.
1520 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1521 uses silc_server_command_whois_parse to parse the request. */
1523 * If normal server, do not parse the WHOIS and IDENTIFY requests
1524 before sending it to the router. Saves some time.
1526 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1528 * Fixed JOIN command on client library. Wrong number of arguments
1529 used to crash the client.
1531 * Added silc_server_channel_has_global function to check whether
1532 channel has global users or not.
1534 * Added silc_server_channel_has_local function to check whether channel
1535 has locally connected clients on the channel.
1537 * The silc_server_remove_from_one_channel now checks whether the
1538 channel has global users or not after given client was removed from
1539 the channel. It also checks whether the channel has local clients
1540 on the channel anymore. If it does not have then the channel entry
1541 is removed as it is not needed anymore.
1543 * The silc_server_notify now checks on JOIN notify whether the joining
1544 client is one of locally connected or global. If it is global then
1545 the channel has now global users on the channel and that is marked
1546 to the channel entry. Also, it now saves the global client to
1547 global list who is joining and JOINs it to the channel. This is
1548 for normal server, that is.
1550 Changed silc_server_send_notify_on_channel,
1551 silc_server_packet_relay_to_channel and
1552 silc_server_packet_send_to_channel check if we are normal server
1553 and client has router set (ie. global client) do not send the
1554 message to that client, as it is already routed to our router.
1556 * Implemented LEAVE notify type handling in silc_server_notify
1559 * Tested LEAVE command in router environment successfully. Tested
1560 with two routers, two servers and two clients.
1564 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1566 * Implemented SIGNOFF notify type handling in silc_server_notify
1569 * silc_server_remove_id now removes the client entry from all channels
1570 it has joined and thusly sends SIGNOFF notify type.
1572 * Rewrote the NAMES list generation in server by removing two excess
1573 loops. The lists are created now inside one loop.
1575 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1577 * silc_server_remove_channel_user checks now also global list
1578 for channel and client.
1580 * silc_server_new_channel_user checks now both local and global
1581 list for channel and client. Fixed a bug in client id decoding.
1582 Used to decode wrong buffer.
1584 * silc_server_channel_message checks now both local and global
1585 list for channel entry.
1587 * Tested channel joining (hence JOIN) in router environment
1588 successfully. Tested with two routers, two servers and two
1591 * Tested channel message sending in router environment successfully.
1593 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1595 * Added silc_server_save_channel_key into server.[ch] to save the
1596 received channel key in Channel Key payload processing. It is
1597 also used in JOIN command reply handling.
1599 Equivalent function silc_client_save_channel_key added into
1600 client.[ch] into client library.
1602 * Changed JOIN command reply to send information whether the channel
1603 was created or not (is existing already) and the channel key
1604 payload. Changed protocol specs accordingly.
1606 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1607 the request was sent by ID and not by nickname. Crashed on
1610 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1612 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1613 now correctly save the received data.
1615 * silc_server_free_sock_user_data now notifies routers in the
1616 network about entities leaving the network.
1618 At the same time implemented functions silc_server_remove_id
1619 and silc_server_send_remove_id to receive and send REMOVE_ID
1620 packets. The packet is used to notify routers in the network
1621 about leaving entities. The ID removed will become invalid in
1624 * Added function silc_idlist_del_server into server. Removes and
1625 free's server entry from ID list.
1627 * silc_server_private_message function now checks, if we are router,
1628 that the destination ID really is valid ID, naturally.
1630 * In router when NEW_ID packet is received (for new client) the
1631 hash of the Client ID is saved in the ID Cache but the
1632 client->nickname is set to NULL, instead of putting the hash
1635 IDENTIFY command now also checks that client->nickname must be
1636 valid. If it is not if will request the data from the server who
1637 owns the client. Added new function
1638 silc_server_command_identify_check.
1640 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1641 to set the command to already allocated Command Payload.
1643 * Tested private message sending in router environment with two
1644 routers, two servers and two clients. Fixed minor bugs and now
1647 * Fixed segfault from client's NAMES command. Used to crash if
1650 * Forwarded packets must not be routed even if it is not destined
1651 to the receiver. Changed server code comply with this.
1653 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1655 * Added `require_reverse_mapping' boolean value to ServerParams
1656 structure. If TRUE (not default) the server will require that
1657 the connecting host has fully qualified domain name.
1659 If the reverse mapping is not required and hostname could not be
1660 found the IP address is used as hostname.
1662 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1664 * Implemented version string checking to both client and server.
1665 The check is incomplete currently due to the abnormal version
1666 strings used in development version of SILC.
1668 * Changed all command functions in server to use the new
1671 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1673 * Changed char *data to unsigned char *data in ID Cache system to
1674 support binary data as ID Cache data. Changed code to support
1675 binary data in lib/silccore/idcache.c.
1677 * Renamed silc_server_packet_relay_command_reply to
1678 silc_server_command_reply as it is normal packet receiving
1679 function. Rewrote the function to accept command replys for
1680 servers and not only for clients.
1682 * Mark remote router always as registered server if we are connecting
1683 to it. Otherwise, commands sent by the router to us are ignored.
1685 * All ID List find routines now returns the ID Cache Entry pointer
1686 as well if requested.
1688 * WHOIS command works now in router environment, tested with two
1689 routers, two servers and two clients.
1691 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1692 in router environment (as it is almost equivalent to WHOIS) but
1693 hasn't been tested thoroughly. Added new functions:
1695 silc_server_command_identify_parse
1696 silc_server_command_identify_send_reply
1697 silc_server_command_identify_from_client
1698 silc_server_command_identify_from_server
1700 * Disabled route cache adding because adding two different ID's with
1701 same IP replaces the old cache entry thus giving wrong route.
1702 The entry->router->connection is always the fastest route anyway
1703 so route cache may not be needed. Of course, new routes maybe
1704 established after receiving the ID when the entry->router->connection
1705 might not be anymore the most optimal.
1707 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1709 * Add route cache for received ID for fast routing.
1711 * Added silc_server_packet_route to route received packet on router
1712 that is not destined to us.
1714 * Renamed silc_server_get_route to silc_server_route_get.
1716 * Added id_string and id_string_len fields into SilcServer to
1717 include encoded ServerID for fast comparing without excess
1718 encoding of the ID's.
1720 * Cleaned up WHOIS command on server side. Added following static
1723 silc_server_command_whois_parse
1724 silc_server_command_whois_check
1725 silc_server_command_whois_send_reply
1726 silc_server_command_whois_from_client
1727 silc_server_command_whois_from_server
1729 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1730 arguments in command replies. All command functions should be
1731 updated to use this macro.
1733 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1735 * Minor typo fixes on command reply handling on server.
1737 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1739 * Added silc_server_command_add_to_channel internal routine to add
1740 the client to the channel after router has created the channel and
1741 sent command reply to the server.
1743 * Added generic silc_server_send_command to send any command from
1746 * Use static buffer with ID rendering instead of duplicating data.
1748 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1750 * Fixed a channel user mode bug when joining to a channel server gave
1751 everybody channel founder rights, oops.
1753 * We mark ourselves as the router of the incoming server connection
1754 if we are router ourselves. This way we can check in some packet
1755 sending functions whether it is locally connected server. For
1756 incoming router connections we put NULL.
1758 * For router sending packets locally means now always sending the
1759 packet cell wide; to local clients and local servers. For normal
1760 server sending packet locally means sending it to only local
1763 * Fixed the JOIN command to really work in router environment. If the
1764 channel is created it is always created by the router. Router is
1765 also responsible of making the initial joining to the channel,
1766 sending JOIN notify to the sending server and distributing
1767 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1768 does not exist server doesn't do anything else but forward the
1769 command to the router which performs everything.
1771 * Added silc_server_send_channel_key function to send the Channel Key
1774 * Added silc_server_create_channel_key to create new channel key. The
1775 channel key is now re-generated everytime someone joins or leaves
1776 a channel, as protocol dictates. Note: channel->key_len is the
1779 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1781 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1782 packet_receive.[ch] to separate packet sending and receiving
1783 routines. The server.[ch] now includes everything else including
1784 actual packet processing (writing and reading data) and other
1787 Renamed silc_server_private_message_send_internal to
1788 silc_server_send_private_message. The routine is still though
1789 used only to relay private messages as server does not send
1790 private messages itself.
1792 Renamed silc_server_new_channel to silc_server_create_new_channel
1793 and added new function sicl_server_new_channel that handles the
1794 incoming New Channel packet. Added also new sending function
1795 silc_server_send_new_channel to send New Channel Payload.
1797 * Added new function silc_server_notify to process incoming notify
1798 packet to the server/router. Server may then relay the notify
1799 to clients if needed.
1801 * Added new function silc_server_new_channel_user to process incoming
1802 New Channel User packet. Router will redistribute the packet and
1803 send JOIN notify to its local clients and locally connected servers
1804 if needed. Normal server will send JOIN notify to its local client
1805 on same channel when received this packet. Added also corresponding
1806 sending function silc_server_send_new_channel_user to sent the
1809 * Added boolean route argument to send_notif_to_channel and
1810 packet_send_to_channel functions to attempt to route the packet
1811 if it is TRUE and send only locally if it is FALSE.
1813 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1815 * silc_server_replace_id now broadcasts the received replace ID
1816 packet if it is not broadcast packet already. The router must
1817 broadcast to inform other routers about changed ID.
1819 * Added backpointer to server's router into SilcServer context in
1820 silcd/server_internal.h.
1822 * Fixed silc_server_packet_broadcast to send correct broadcast
1825 * The channel key is now distributed to the local client as soon
1826 as it is received from the router (in router environment) so that
1827 no other packet may be sent for the channel until client has
1830 * silc_server_remove_channel_user now broadcasts the received
1831 Remove Channel User packet if it is not broadcast packet already.
1832 The router must broadcast to inform other routers about removed
1835 * Added users field into SilcPacketContext that is a reference count
1836 of the context. One can increase the reference count by calling
1837 silc_packet_context_dup which is now changed to just increase the
1838 reference count instead of duplicating the data. The reference
1839 count is decresed by calling silc_packet_context_free that will
1840 free the data after the reference count hits zero.
1842 For now on the packet context and everything allocated into it
1843 (including the raw packet from network) must be freed by calling
1844 the new silc_packet_context_free function. Added also new function
1845 silc_packet_context_alloc that must be used now to allocate the
1846 context. This also means that if a routine is asynchronous from
1847 silc_[client/server]_packet_parse_type the packet context must
1848 be duplicated by calling silc_packet_context_dup. Otherwise it
1849 gets free'd after silc_[client/server]_packet_parse_type returns.
1850 Also, one must remember that if packet is duplicated then its
1851 reference count must be decresed by calling the free function as
1852 many times as it was duplicated.
1854 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1855 from both client and server.
1857 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1859 * Made joining to a channel working in router environment.
1861 * Cleaned up JOIN command on server side and create function
1862 silc_server_command_join_channel internal routine to make the
1865 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1867 * Changed silc_command_pending list to SilcDList. Also, added
1868 `ident' field to SilcServerCommandPending structure to identify
1869 the reply and to call correct callback.
1871 Added silc_server_command_pending_check function to replace the
1872 corresnponding macro. The silc_command_pending list is not
1875 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1876 to set identifier to previously allocated Command Payload. It
1877 is used to set identifier for command when resending Command
1880 * Added silc_command_payload_encode_payload to encode Command
1881 Payload buffer from SilcCommandPayload structure.
1883 * Added silc_argument_payload_encode_payload to encode Argument
1884 payload buffer from SilcArgumentPayload structure.
1886 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1888 * Changed WHOIS command to support router connection on server side.
1889 The whois request is always sent to router unless the server is
1890 standalone server. After server has received the reply from the
1891 router will it send the reply to the client.
1893 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1894 broadcast received broadcast packet. The function is used only
1895 by router. The broadcast packet is always sent to the router's
1898 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1899 render given ID to printable string, for log files for example.
1901 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1903 * Made basic router to router connections working. At least they
1904 can now connect to each other but nothing really works the way
1905 they are supposed - yet.
1907 * Added new initiator token to RouterConnection configuration
1908 file in silcd/serverconfig.[ch]. It is used to tell whether we
1909 are the initiator to the remote router or whether we'll expect
1910 the other end to connect.
1912 * Moved registering of listener task to silc_server_init, hence
1913 the server starts listenning as soon as it is run, even if it
1914 does not have connections to other routers. Let's see how well
1917 * Changed default connection retry timeouts for more suitable in
1920 * Removed cipher and such arguments from silc_idlist_add_client
1921 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1922 Added new function silc_idlist_add_data to add the keys and stuff
1925 * Added SilcIDListData structure and added it to SilcClientEntry
1926 and SilcServerEntry as their first field in the structure. This
1927 way we can explicitly cast the ID entries to the SilcIDListData
1928 structure and get common data for the entries. In past, we had
1929 to first check what type of connection it is and then cast it to
1930 correct ID entry type. Now, we can directly cast the opaque
1931 pointer to the SilcIDListData (no matter what ID entry it actually
1932 is) and get the data needed.
1934 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1936 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1937 in some circumstances even if threre were timeout tasks, though not
1938 IO tasks, but tasks anyway. Now fixed.
1940 * Defined SilcServerConnection structure to hold connection specific
1941 stuff about directly connected servers and routers. The definition
1942 is currently in silcd/server_internal.h. I thought about having
1943 a bit more important role fro this struct but for now it is used
1944 only when connecting to other server (or router actually).
1946 * Added connecting retry support in server when connecting to
1947 router(s). The retry feature implement exponential backoff
1948 algorithm. Also, added SilcServerParams structure to hold default
1949 parameters for server. For now, it include these retry settings
1950 and are hard coded. After server is moded to be as Silc Server
1951 Library this structure will be more important.
1953 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1955 * Changed client librarys channel->clients table to SilcList and
1956 changed code accordingly.
1958 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1960 * Changed client's channel table to SilcList and changed code
1961 accordingly. Also changed SilcChannelClientEntry to include back-
1962 pointer to the channel so that client entry can use that structure
1963 as list as well and we have fast cross-reference to the channel.
1964 This change dramatically decreased the complexity of channel
1965 handling with client entry and vice versa (removed one extra
1966 loop when searching for channel entry from many functions).
1968 * Changed server->sim from table to SilcDList and changed code
1971 * NAMES command can now be used from user interface. It will show
1972 the user list on the channel, neatly.
1974 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1975 Code now saves realname of the user if it becomes available.
1977 * Renamed configure.in to configure.in.pre and made ./prepare
1978 script to automatically add correct version string to
1979 configure.in which it creates from configure.in.pre.
1981 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1983 * NAMES command reply now shows users mode with the nickname when
1986 * Moved silc_client_ch[u]mode[_char] functions from
1987 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1988 place sucks, they are utility functions and should be in some
1991 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1993 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1996 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2000 * Added TRQ (efficient deque and list library) into lib/trq. This is
2001 a very good list library that is currently used in the SILC. Defined
2002 SilcList API over the library because I didn't like the API very
2003 much. See lib/trq/silclist.h for the API and examples of how to
2004 use the API. Fixed various places in the code to use the new
2005 SilcList API. The SilcList is meant for lists that has a structure
2006 already defined as a list. It is not suitable to add just some
2007 context to the list (in TRQ, the context is the list actually).
2009 So, I defined SilcDList that can be used for the purpose where
2010 predefined list structure does not exit. This can be used as
2011 such list. Now some context just can be added to the SilcDList.
2012 Currently this list is not used in the SILC just yet, though there
2013 are a lot places where this can replace dynamically allocated
2014 tables and I will fix these places, later, to use SilcDList.
2015 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2016 and use TRQ internally).
2018 Also fixed some annoying warning messages that the original TRQ
2019 code generated. Also minor changes to TRQ's Makefile.in.
2021 * Added support for querying by Client ID to both WHOIS and
2022 IDENTIFY commands into server, as required by the protocol.
2024 * Removed method function pointers from SilcBuffer structure. They
2025 weren't used to anything and just increased the context size for
2026 no good reason. This change also made silc_buffer_alloc and
2027 silc_buffer_free functions inline functions.
2029 * Disabled command flooding detection support until it's fixed so
2030 that it accepts commands in but does not execute them more than once
2033 * Added silc_net_localhost(), to return local hostname, into
2034 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2035 that must be initialized before calling silc_client_init.
2037 * Added new function: silc_server_send_notify_on_channels to send
2038 notify messages to all channels client has joined. It is assured
2039 that the message is sent only once per client.
2041 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2042 lib/silcutil/silcutil.[ch] as silc_format function. The new
2043 function is generic and is used by server as well, not only by
2044 the logging routines.
2046 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2047 the provided version string was not acceptable. Added new function:
2048 silc_ske_check_version into lib/silcske/silcske.h. The function
2049 must be implemented by the application (client or server) and it
2050 does not reside in the SKE library. The function checks the version
2051 string remote end sent.
2053 * Added back pointers (to opaque context and to SilcSocketConnection)
2054 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2056 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2057 duplicate packet context structure.
2059 * Changed `notify' client operation to send same arguments as client
2060 receives from server except for ID's. ID's are mapped to correct
2061 ID entry and that is returned. Also, if channel entry is not sent
2062 by server but the notify is for channel the channel entry is sent
2063 to application (otherwise application doesn't know that it is for
2064 channel (library gets it from packet's Destination ID)).
2066 * Added silc_client_remove_from_channels into client library to
2067 remove a client from all channels it has joined to. Used when
2068 received SIGNOFF notify from server. Added also new function
2069 silc_client_replace_from_channels to replace old ID entry with
2070 new ID entry on all channels. Used when received NICK_CHANGE
2073 * Fixed ID Cache list handling in silc_idlist_get_client in
2074 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2075 to get (or query) client by ID.
2077 * Updated TODO list.
2079 * Added connection authentication status message defined by the
2080 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2081 support for these into the code in client and server side.
2083 * Added generic function silc_client_send_command to send any command
2084 with variable argument list. Application should use this function
2085 to send commands if the command functions provided by the library
2086 does not suite for the application's user interface needs.
2088 * Added new `failure' client operation. Application is notified about
2089 received failure packet if client is executing a protocol. In this
2090 case the protocol's execution has failed.
2092 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2093 is required by the protocol.
2095 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2096 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2099 * Added status flag to SilcSKE object to indicate realtime status
2100 of the SKE protocol.
2102 * Application receives now exactly same command reply arguments as
2103 the library receives from server. However, if ID is received the
2104 corresponding ID entry is returned to the application (eg. Client
2105 ID is mapped to correct SilcClientEntry entry and that is returned).
2106 Changed command_reply client operation due to this change.
2108 * Changed all ID's in commands and in command replys as ID Payloads.
2109 Change affected both client and server side codes.
2111 All ID's sent in SILC network (with execption of ID's in SILC
2112 Packet header) are sent in ID Payload to support variable length
2115 * Server now notifies nick changes and notifies all clients on
2116 the channels about the new nickname (about the new Client ID,
2119 * Implemented CMODE command to change channel modes. Supports all
2120 channel modes defined by the protocol specs except ban and invite
2121 lists. (Also, private channel key mode is supported but support for
2122 setting private channel key in client is missing, thus, this mode
2123 has no effect on client side (except that server requires that the
2124 client uses private channel key and normal channel traffic does not
2127 Also, invite mode works per se, but INVITE command does not work
2128 yet correctly, so you can set channel as invite only channel but
2129 inviting clients to the channel does not work (it is yet to be
2130 thought what's the best way to do it).
2132 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2133 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2134 Implemented CUMODE command to change user's mode on the channel.
2135 Supports all modes defined by the protocol specs.
2137 * Added NAMES command reply to return users modes on the channel.
2139 * Removed unnecessary and slow ciphers from lib/silccrypt.
2141 * Set SO_KEEPALIVE option to connection sockets by default.
2143 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2145 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2146 redefined the Notify Payload into protocol specs.
2148 * Added silc_id_payload_parse_id to get ID directly from raw
2151 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2153 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2154 accept searching by Client ID as well.
2156 * Added support for LEAVE and SIGNOFF notify types in client library.
2158 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2159 to parse ID Payload from raw data.
2161 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2163 * Added flags parameter into silc_ske_assemble_security_properties
2164 function in lib/silcske/silcske.[ch].
2166 * Changed notify client operation to fit better for notify messages
2167 sent by server. The notify payload received from server is now
2168 passed to the application (after parsing it to SilcNotifyPayload).
2169 It is application's responsibility to retrieve the arguments
2170 from the payload and show the message the way it wants. The message
2171 sent by server is implementation specific.
2173 * Changed public keys to comply with the protocol specification.
2174 Old public keys are not supported anymore and are not compatible.
2176 * Removed nickname from Channel Payload as the latest draft removed
2177 it. The client must resolve the nickname from the NAMES command
2178 reply received when it joined the channel.
2180 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2182 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2184 * Fixed some errors in protocol specification drafts.
2186 * Created lib/silccore/silcnotify.c to implement Notify Payload
2187 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2188 generic payloads described by protocol specifications. The file
2189 includes implementations for ID Payload and Argument Payload.
2191 * Changed Command Payload implementation to use the new Argument
2192 Payload. Changed command_xxxx_payload to command_payload_xxxx
2193 to comply with SILC coding conventions.
2195 * Added suppport for Argument Payload handling in Notify Payload
2196 implementation as protocol requires it. Added the new support
2197 into server and client lib as well.
2199 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2201 * Added support for multiple nicknames on same channel. [n] is
2202 added locally to the nickname if there are more than one same
2203 nicknames on the channel.
2205 * Server now sends all nicknames that matched WHOIS request.
2206 Client also shows the list received from server.
2208 * Added TOPIC command to client side. User can now set and show
2209 current topic on channel.
2211 * Added MOTD command to client and server. Also, server sends the
2212 motd when client connects to the server.
2214 * Changed version strings to comply ISO 8601.
2216 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2218 * Fixed protocol error handling in client library. It should now
2219 cope even if the SKE fails for some reason.
2221 * Made new protocol specification drafts for submitting to IETF.
2223 * Implemented TOPIC command to server in silcd/command.c.
2225 * Added two new notify types into lib/silccore/silcnotify.h:
2226 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2227 notify nickname change and topic setting/change on a channel.
2229 * API change of command_reply operation in client library. The
2230 application gets now the status type received from server as well.
2232 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2234 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2236 * Cras fixed and optimized the packet handling even further and
2237 it should work now. Minor change to the prototype of function
2238 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2240 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2242 * Added new function into lib/silcutil/silcschedule.[ch]:
2243 silc_schedule_with_fd to select() a specified fd. The function
2244 returns after timeout expires or data arrives or goes. The
2245 function is used by packet routines to wait that all data is
2246 received from network.
2248 * Fixed data reading from network in lib/silccore/silcpacket.c.
2249 The code now assures that all data is read from the fd and then
2250 continues packet processing. This was a bug fix since the code
2251 used to drop some data in some circumstances.
2253 * Added new function into lib/silcclient/client.[ch]:
2254 silc_client_start_key_exchange to start key exchange after
2255 connection has been established to server. The code internally
2256 now uses this funtion but its main purpose was to provide it
2257 for applications that perform their own connecting. After
2258 application has created a connection it merely calls this
2259 function to start the key exchange between client and server.
2260 The library takes care of everything else after that.
2262 Updated also lib/silcclient/README to explain the usage of
2265 * Do not send to application information that connection has
2266 been established. Application gets notified it by connect
2269 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2271 * Applied cras's patch to add silc_schedule_one function. The
2272 function runs scheduler once and returns.
2274 * Fixed the scheduler after cras messed it up. The timeout
2275 handling works now as it's supposed to work.
2277 * Added into lib/silccore/ silcnotify.h to include notify
2278 message types support. Changed silc_server_send_notify*
2279 functions, in server.[ch], to support those new notify types.
2280 Added the support for the notify types into client library,
2281 as well. Added new notify client operation into ops.h in
2284 * Changed silc_server_packet_send_to_channel to send normal
2285 packets instead of just channel message packets. The function
2286 is now used to send the notify packets to channels. It is not
2287 used to send channel message packets anymore, as server never
2290 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2291 va_arg()s as it seems to require it nowadays. I guess, if SILC
2292 is compiled with older va_arg() the new code should work anyway.
2294 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2296 * Splitted core library. Core library (lib/silccore) includes
2297 now only SILC protocol specific core (and common) components.
2298 Created new utility library (lib/silcutil) that includes more
2299 generic purpose stuff. The stuff for util library was taken
2300 from the old core library. This was minor and easy split.
2302 * Created SILC Client Library (lib/silcclient) that includes
2303 implementation of the SILC client without user interface. This
2304 was major move from silc/ directory. The code has been changed
2305 so that it is transparent towards the user interface. The
2306 silc/ directory includes now the same user interface as before
2307 and it uses the new client library. Read lib/silcclient/README.
2308 Basicly, the client library performs everything else related
2309 to SILC except user interface handling. Also, configuration
2310 files are considered to be part of user interface and library
2311 does not handle them.
2313 This change also changed a lot of structures, function naming etc.
2314 Most important change was that SilcClientWindow object was
2315 renamed to SilcClientConnection in the client library. Created
2316 also new file lib/silcclient/ops.h. Also added new files
2317 silc/local_command.[ch] and silc/client_ops.[ch].
2319 All these changes were made to make it easier for user interface
2320 designers to create what ever user interface for the SILC client
2323 It is also expected that the server will be moved to lib
2324 directory as well and SILC Server Library will be created;
2325 sometimes in the future.
2327 * Removed Local commands from lib/silccore/silccommand.h as
2328 they are application specific and new client library does not
2329 handle any of those anymore.
2331 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2332 old client implementation in silc/.
2334 * Added support for callback functions in SILC_LOG_* macros.
2335 Application can now set its own callbacks that will be called
2336 instead of using the default functions that will always print
2337 the debug messages to stderr (or stdout). Also, debugging can
2338 now be disabled by setting silc_debug to FALSE and re-enabled by
2339 setting it to TRUE. Note, that logging will still work even
2340 if debugging is disabled.
2342 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2343 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2344 silc_log_reset_debug_callbacks.
2346 * To enable debugging in silc client one must give now -d
2347 option on command line.
2349 * Changed silc_schedule_init to automatically allocate task queues
2350 if they are not allocated before calling it.
2352 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2354 * Added GMP 3.1 into math library.
2356 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2358 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2359 a channel in SILC network. The packet is used by servers and
2360 routers to notify other routers that user has left a channel.
2361 This little feature was missing until now. Added the feature
2362 to protocol specification as well.
2364 Added functions: silc_server_send_remove_channel_user and
2365 silc_server_remove_channel_user into server.[ch].
2367 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2368 lib/silccore/silcpacket.h. However, they are not implemented
2371 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2373 * Fixed joining to a channel and sending channel messages
2374 between server and router. The channel message sending should
2375 now work inside a cell.
2377 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2379 * Fixed the private message sending between server and router.
2380 The private message sending should now work inside a cell.
2382 * Added silc_server_replace_id into server.[ch] to replace
2383 existing ID in the SILC network.
2385 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2386 and silc_idlist_replace_server_id into idlist.[ch] in server.
2388 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2390 * Fixed the server to server connections. Server can again now
2391 connect to router. Router to router connections probably does
2394 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2396 * Added dynamic protocol registering support. Now protocols can
2397 registered and unregistered on the fly. Patch by cras.
2399 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2401 * Added lib/contrib directory to hold routines that some platforms
2402 don't have but are needed by SILC.
2404 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2405 into lin/contrib to provide getopt() and getopt_long() for
2406 those who don't have it.
2408 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2410 * Added AWAY command to client. When away message is set and
2411 client receives a private message packet the client automatically
2412 replies to the sender with the away message.
2414 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2415 bug seemed to be the cause of recent problems when compiling
2418 * Added version detection support to SKE protocol specification
2419 and added the new changes to the SKE implementation as well.
2420 There were other minor changes in the SKE protocol as well.
2422 Many changes in lib/silcske/silcske.[ch] and in
2423 lib/silcske/payload.[ch].
2425 * Added ^U functionality, clear input line. Patch from cras.
2427 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2429 * Mainly small bugfixes on core library. Fixed some debugging
2430 logging and buffer overflow in silclog.c.
2432 * Updated config.sub and config.guess on the distribution tree.
2434 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2436 * Added command lagging support in server. Client may execute
2437 commands now only once in two seconds.
2439 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2441 * Optimized packet reception. MAC computation and checking is now
2442 also more optimized. A lot previously duplicated code is now
2443 used as generic by both client and server.
2445 * Fixed key pair generation in clientutil.c
2447 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2449 * Added into lib/silccore/silcbufutil.[ch] new function;
2450 silc_buffer_realloc.
2452 * Moved generic packet sending/encryption functions to
2453 lib/silccore/silcpacket.[ch] from client and server. Some
2454 rewriting of the functions.
2456 * Moved all generic packet reception/decryption functions to
2457 lib/silccore/silcpacket.[ch] from client and server. The
2458 packet processing is now much cleaner in both client and server.
2459 These were major changes in both client and server.
2461 * Created many common functions in server to do packet sending.
2462 Previously code were duplicated a lot, this has been removed
2465 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2467 * Rewrote major parts of the ID cache system. Don't know
2468 whether it is better now or not but at least the API is more
2471 * Major rewrite on ID cache stuff on client because of the ID
2472 cache API changes. Added idlist.c to client.
2474 * Also major rewrite on ID cache stuff on server as well.
2475 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2476 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2477 in hand, instead they are all put into the ID cache system now.
2478 All server_idlist_* routines uses ID cache now instead of
2479 traversing its own lists (those lists does not exist anymore).
2480 SilcIDList though still exists. Also, SilcXXXEntry's are
2483 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2485 * Finally made the SKE implementation compliant to the protocol
2486 specification. All mp integers are now binary encoded as
2487 opposed being HEX encoded.
2489 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2492 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2493 functions: silc_[encode/decode]_pem. Also added function
2494 silc_encode_pem_file to PEM encode with newlines ('\n') for
2497 * SILC public keys are now encoded either PEM or binary. Same
2498 option is for private keys as well. By default private keys
2499 are binary encoded and public keys PEM encoded. Silly HEX
2500 encoding were removed.
2502 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2503 function to create fingerprints.
2505 * Fixed a bug in SHA1; does not change the original data anymore.
2507 * Partly implemented INFO command on client and server side.
2508 Fixed CLEAR command. Changes to SERVER command; show current
2509 server(s) when giving command without arguments. Added
2510 VERSION command to client.
2512 * Added check to server that unregistered connections cannot
2513 execute commands (unless it is specificly allowed).
2515 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2517 * Fixed screen refresh.
2519 * Fixed channel joining bug from client. On some circumstances
2520 client tried to join to a channel it had already joined.
2522 * Added public key verification process into client's protocol.c.
2523 The client now verifies the public key from user and saves
2524 it into ~./silc/serverkeys/ directory.
2526 Added into: clientutil.[ch]: silc_client_verify_server_key.
2528 * Changed SKE protocol's silc_ske_initiator_finish function
2529 to accept callback function that verifies the received public
2530 key. Removed old silc_ske_verify_public_key function.
2532 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2534 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2535 silc_pkcs_private_key[_data]_set.
2537 * Made the password and public authentication more cleaner in
2538 server's protocol.c.
2540 * Removed historic and obsolete protocol `channel_auth' from
2541 both client and server.
2543 * Removed wrong way of sending command status messages from
2544 server to client in server's command.c. The old way violated
2545 protocol specification.
2547 Changes to silccore/silccommand.[ch]: removed
2548 silc_command_encode_status_payload -> not needed anymore,
2549 changed silc_command_encode_payload_va to accept extra
2550 argument on variable argument list. The argument type must
2551 now be provided to the function. Also, added new function:
2552 silc_command_encode_reply_payload_va which is same as
2553 normal command_encode_payload_va except command status type
2554 is provided as extra argument.
2556 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2558 * Added ~./silc directory handling. The directory includes the
2559 public and private keys for the client.
2561 Added silc_client_check_silc_dir, silc_client_create_identifier
2562 and silc_client_load_keys.
2564 * Implemented SILC protocol compliant public key. Added public
2565 and private key saving to and loading from files.
2567 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2568 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2569 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2570 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2571 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2573 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2574 silc_pkcs_load_[public/private]_key.
2576 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2578 * Added silc_server_get_route (route.[ch]) to get connection
2579 data for the fastest route for given ID.
2581 * Implemented INVITE command on client and server. The command
2582 were re-defined in the SILC Protocol Specification and the
2583 implementation now complies with the specification.
2585 * Implemented PING command on client and server.
2587 * Implemented NAMES command on client and server. The server side
2588 supports currently only normal server not router server yet.
2589 Some changes to NAMES definition in SILC protocol specification.
2591 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Implemented LEAVE command on client and server.
2595 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2596 again. This change was made to the protocol as well. Server
2597 should not violate the protocol specification anymore.
2599 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2601 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2602 was tested. SOCKS4 was not but should work anyway.
