1 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added one new argument <user mode> to the WHOIS command reply
4 to return the mode of the user in SILC. Updated the protocol
7 Implemented it to the server and client.
9 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
11 * Fixed the mode printing on the user interface on joining.
12 Affected file silc/client_ops.c.
14 * Implemented the UMODE command and user modes in general to the
15 client library and to the user interface.
17 * Implemented the UMODE command to the server.
19 * The server now sends UNKNOWN_COMMAND error status if client sends
20 unknown command. Affected file silcd/command.c.
22 * All server commands now handle the command identifier the right
23 way when sending the command reply to the client. The client can
24 use to identify the command replies with the identifier.
26 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
28 * Added silc_server_get_client_route to resolve the route to
29 the client indicated by the client ID. Affected file is
32 * Added silc_server_relay_packet as general function to relay
33 packet to arbitrary destination. This deprecates functions
34 like _send_private_message_key, _relay_notify etc. Affected
35 file is silcd/packet_send.[ch].
37 Removed silc_server_send_key_agreement,
38 silc_server_send_private_message_key and
39 silc_server_packet_relay_notify functions from the file
40 silcd/packet_send.[ch].
44 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
45 server. Affected file silcd/packet_receive.[ch].
47 * Implemented the KILL command to the client. Implemented the
48 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
49 Affected files lib/silcclient/command[_reply].c and
50 lib/silcclient/client_notify.c. Implemented the KILL notify
51 printing in the user inteface.
53 * Fixed a lot silc_parse_nick memory leaks from the client
54 library in the file lib/silcclient/command.c.
56 * Changed the silc_server_send_notify_on_channels's `sender'
57 argument from SilcSocketConnection to SilcClientEntry to
58 check the sender as entry and not as connection object and not
59 to send to the client provided as argument. The affected file
60 is silcd/packet_send.[ch].
62 * The notify packets that are destined directly to the client used
63 to not to be processed by the server. Now changed that and the
64 server processes all notify packets. After relaying the packet
65 to the client the notify packet is processed in the server.
67 * The silc_server_free_client_data now checks whether there is
68 pending outgoing traffic for the client and purges the data to
69 the network before removing the client entry.
71 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
73 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
74 an client is killed from the SILC Network. Updated the protocol
77 Added new function silc_server_send_notify_killed to the
78 silcd/packet_send.[ch].
80 * Added function silc_server_packet_relay_notify to relay notify
81 packets that are destined directly to a client. In this case
82 the server does not process the notify packets but merely relays
83 it to the client. Affected file silcd/packet_send.[ch].
85 Added also silc_server_packet_process_relay_notify to check
86 whereto relay the notify. Affected file is
87 silcd/packet_receive.[ch].
89 * Implemented the KILL command to the server.
93 * Added the backup schema desgined last fall to the protocol
94 specs for everyone to see. The specification is in the
95 *-spec-xx.txt draft and the packet type definitions for the
96 backup routers is in *-pp-xx.txt draft. Thusly, added also
97 new packet type SILC_PACKET_CELL_ROUTERS.
99 * A big security problem in the implementation discovered. The
100 signoff of an client did not cause new channel key generation
101 which it of course should've done. The channel keys must be
102 always re-generated when client leaves (or signoffs) the channel.
103 The silc_server_remove_from_channels funtion now handles
104 the channel key re-generation.
106 * Added `sender' argument to the silc_server_send_notify_on_channels
107 to not to send the client provided as argument. Affected file
108 silcd/packet_send.[ch].
110 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
112 * Implemented OPER and SILCOPER commands into the server and
115 * Added silc_auth_verify and silc_auth_verify_data to verify
116 the authentication directly from the authentication payload.
117 It supports verifying both passphrase and public key based
118 authentication. Affected file lib/silccore/silcauth.[ch].
120 * Added `hash' field to the SilcIDListData structure. It is the
121 hash negotiated in the SKE protocol. Affected file is
124 * Slight redesigning of the SilcAuthPayload handling routines.
125 Do not send SilcPKCS but SilcPublicKey as argument.
127 * Implemented the public key authentication support to the
128 serverconfig. The public key is loaded fromthe provided path
129 and saved as authentication data to void * pointer. Thus,
130 changed the unsigned char *auth_data to void *auth_data;
132 * Fixed SHUTDOWN command to send the reply before the server
133 is shutdown. :) Affected file silcd/command.c.
135 * Fixed fatal bug in CONNECT command. The hostname was invalid
136 memory and server crashed. Affected file silcd/command.c.
138 * Fixed fatal bug in CLOSE command. The server_entry became
139 invalid but was referenced later in the command. Affected file
142 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
144 * Fixed fatal bug in failure packet handling. Server ignored
145 the failure and thus crashed when it came.
149 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
151 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
152 that the command may be executed only once in (about) 2 seconds.
153 The old SILC_CF_LAG flag is same but allows command bursts up
154 to five before limiting.
156 Added the support for CF_LAG and CF_LAG_STRICT flags to the
157 server code. Various commands now includes the CF_LAG_STRICT
158 flag to disallow any kind of miss-use of the command.
160 * Fixed the silc_buffer_unformat to not to allocate any data
161 if the length of the data is zero. It used to allocate the
162 length + 1. Affected file lib/silcutil/silcbuffmt.c.
164 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
166 * Changed the format of AdminConnection configuration section
167 in the server. Added username of the admin to the format.
168 Affected files silcd/serverconfig.[ch].
170 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
171 to return admin configuration data by host, username and/or
174 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
176 * Implemented WHOWAS command to the server. Added the functions:
178 silc_server_command_whowas_parse,
179 silc_server_command_whowas_send_reply,
180 silc_server_command_whowas_from_client and
181 silc_server_command_whowas_from_server
183 * Added <Client ID> argument to the WHOWAS command reply. Updated
184 the protocol specs accordingly.
186 * Implemented WHOWAS command and command_reply to the client
189 Implemented the WHOWAS printing on the user interface.
191 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
193 * Added new argument to the WHOWAS command reply, the real name.
194 It is an optional argument. Updated the protocol specs.
196 * Added SilcIDCacheDestructor callback that is registered when
197 the SilcIDCache is allocated. The callback is called when
198 an cache entry in the ID Cache expires, or is purged from the
199 cache. Added into lib/silccore/idcache.[ch].
201 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
202 to destruct the client entries when the cache entry expires.
203 Other ID Cache's in server and in the client library ignores
206 * If the ID Cache entry's `expire' field is zero then the entry
207 never expires. Added boolean `expire' argument to the
208 silc_idcache_add function in the lib/silccore/idcache.[ch].
209 If it is TRUE the default expiry value is used.
211 * Added silc_server_free_client_data_timeout that is registered
212 when client disconnects. By default for 5 minutes we preserve
213 the client entry for history - for WHOWAS command.
215 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
217 * Added support to the server to enforce that commands are not
218 executed more than once in 2 seconds. If server receives
219 commands from client more frequently, timeout is registered
220 to process the commands. Affected file silcd/command.c.
221 Added new function silc_server_command_process_timeout.
223 * Changed NICK_NOTIFY handling in client library to check that
224 if the client's nickname was changed, so there is no need to
225 resolve anything from the server.
227 * Removed error printing from the WHOIS and IDENTIFY commands.
228 If error occurs then it is ignored silently in the client library.
229 The application, however, may map the received error to
230 human readable error string. The application currently maps
231 the NO_SUCH_NICKNAME error to string.
233 * Made the command status message public to the application. Moved
234 them from lib/silcclient/command_reply.c to
235 lib/silcclient/command_reply.h. The application can map the
236 received command status to the string with the
237 silc_client_command_status_message function.
239 * Added check to the server to check that client's ID is same
240 as the Source ID in the packet the client sent. They must
243 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
245 * Added dist-bzip hook to the Makefile.am to make bzip2
246 compressed distributions.
248 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
250 * Server now enforces the maximum length for the nickname and
251 the channel as protocol specification dictates. 128 bytes for
252 nickname and 256 bytes for channel name.
254 * Moved the WHOIS printing to the application. The client libary
255 does not print out the WHOIS information anymore, the application
256 must do it. Renamed silc_client_command_reply_whois_print to
257 the silc_client_command_reply_whois_save.
259 The client's idle time is also sent to the application now, and
260 the idle is shown on screen.
262 * Added silc_client_command_reply_identify_save to save the
263 received IDENTIFY entries.
265 * Do not check for channel private keys in message sending and
266 reception if the channel does not have the PRIVKEY mode set.
267 Affected file lib/silclient/client_channel.c.
269 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
271 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
272 just surfaced after chaning the JOIN procedure.
274 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
276 * Added silc_client_get_clients_by_list to get client entries
277 from Client ID list, that is returned for example by JOIN
278 and USERS command replies. The application should use this
279 function for example when JOIN command reply is received to
280 resolve the clients already on the channel (library does not
281 do that anymore as USERS command reply is not used in the JOIN
282 procedure anymore). Affected files lib/silcclient/silcapi.h and
283 lib/silcclient/idlist.c.
285 * JOIN command reply and USERS command reply returns now SilcBuffer
286 pointers instead of unsigned char pointers when returning
287 the client list and mode list.
289 * Added <Client ID> argument to the JOIN command reply, mainly
290 for the server to identify for which client the command was
291 originally sent. Updated protocol specs accordingly.
293 * Added SilcDlist private_key pointer to the SilcChannelEntry
294 in the client to support the channel private keys. Affected
295 file is lib/silcclient/idlist.h.
297 * Added SilcChannelPrivateKey argument to the function
298 silc_client_send_channel_message so that application can choose
299 to use specific private ke if it wants to. If it is not provided,
300 the normal channel key is used, unless private keys are set.
301 In this case the first (key that was added first) is used
302 as the encryption key.
304 * Implemented the support for channel private key handling.
305 Implemented the following functions:
307 silc_client_add_channel_private_key,
308 silc_client_del_channel_private_keys,
309 silc_client_del_channel_private_key,
310 silc_client_list_channel_private_keys and
311 silc_client_free_channel_private_keys
313 Affected file lib/silcclient/client_channel.c.
315 * Added the support for the private keys in the channel message
316 sending and encryption and in the message reception and
317 decryption. Affected funtions are
318 silc_client_send_channel_message and silc_client_channel_message.
320 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
322 * Added SKE's key verify callback to the client library's
323 KE protocol context. Affected files lib/silcclient/protocol.[ch].
325 * Removed the statement that server (or router) must send USERS
326 command reply when joining to the channel so that the client
327 knows who are on the channel. Instead, the client list and
328 client's mode list is now sent in the JOIN command reply to the
329 client who joined channel. This is better solution.
331 * Added function silc_server_get_users_on_channel and function
332 silc_server_save_users_on_channel to the silcd/server.[ch].
334 * Removed function silc_server_command_send_users from the
337 * Do not show topic on the client library anymore. The topic is
338 sent in the command reply notify to the application and the
339 application must show the topic now.
341 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
343 * Added client searching by nickname hash into the IDENTIFY and
344 WHOIS commands in the server as they were clearly missing from
345 them. Affected file is silcd/command.c.
347 * Fixed a bug in private message receiving in the client library.
348 The remote ID was freed and it wasn't supposed, now it is
351 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
353 * Minor fix to the channel payload; allocate the data area, as it
354 needs to be of specific length.
356 * If the key agreement port is zero then the operating
357 system will define the bound port. Affected files are
358 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
360 * Added new function silc_channel_payload_decrypt into the file
361 lib/silccore/silcchannel.[ch].
363 * Moved the channel message etc, check from silc_packet_decrypt
364 to applications. The library calls now a generic
365 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
366 when the packet is either normal or special. This was done to
367 allow more wide range of checking that was not allowed when
368 the code was in library. Now applications can do virtually any
369 checks to the packet and return to the library the decision how
370 the packet should be processed. Affected files are
371 lib/silccore/silcpacket.[ch].
373 Added silc_server_packet_decrypt_check to the server and
374 silc_client_packet_decrypt_check to the client library.
376 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
377 to send with specified source and destination information.
379 * Channel message delivery between routers was broken after the
380 channel key distribution was fixed earlier. The channel key
381 was used be to distributed to other routers as well which is not
382 allowed by the protocol. Now this is fixed and channel keys
383 really are cell specific and the channel message delivery between
384 routers comply with the protocol specification.
386 * Fixed various commands in server to check also the global list
387 for the channel entry and not just the local list. The affected
388 file silcd/command.c.
390 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
392 * Added assert()s to buffer formatting and unformatting routines
393 to assert (if --enable-debug) when error occurs. Affected
394 file: lib/silcutil/silcbuffmt.c.
396 * Changed to auto-reconnect to check whether the remote host is
397 router and register the re-connect timeout if it is. It used
398 to check that whether we are normal server, but router must do
399 auto-reconnect with another router as well. Affected file
402 * Removed the [<key len>] option from CMODE command as the cipher
403 name decides the key length, nowadays. See the defined ciphers
404 from the protocol specification.
406 * Added [<hmac>] option to the CMODE command to define the HMAC
407 for the channel. Added SILC_CMODE_HMAC channel mode.
409 * Added [<hmac>] option for the JOIN command so that user can
410 select which HMAC is used to compute the MACs of the channel
413 * Added Hmac field to the Channel Message Payload. The integrity
414 of plaintext channel messages are now protected by computing
415 MAC of the message and attaching the MAC to the payload. The
416 MAC is encrypted. Now, it is clear that this causes some
417 overhead to the size of the packet but rationale for this is that
418 now the receiver can verify whether the channel message decrypted
419 correctly and also when private keys are set for the channel the
420 receiver can decrypt the packet with several keys and check from
421 the MAC which key decrypted the message correctly.
423 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
424 lib/silccrypt/silccipher.[ch].
426 * Added silc_hash_len to return the digest length into the
427 lib/silcrypt/silchash.[ch].
429 * Rewrote parts of Silc Channel Payload interface in the
430 lib/silccore/silcchannel.[ch]. The encode function now also
431 encrypts the packet and parse function decrypts it.
433 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
435 * Fixed a minor formatting bug in the SKE's key material processing.
436 It actually might have processed the keys wrong way resulting
439 * Redefined the mandatory HMAC algorithms and added new algorithms.
440 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
441 and hmac-md5 truncated to 96 bits. The mandatory is now
442 hmac-sha1-96. Rest are optional (including the one that used
443 to be mandatory). Rationale for this is that the truncated HMAC
444 length is sufficient from security point of view and can actually
445 make the attack against the HMAC harder. Also, the truncated
446 HMAC causes less overhead to the packets. See the RFC2104 for
449 * Added new [hmac] configuration section. The SKE used to use
450 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
451 is of course wrong. The official names that must be proposed in
452 the SKE are the ones defined in the protocol specification
453 (hmac-sha1-96 for example). The user can configure any hmac
454 using any hash function configured in the [hash] section. At
455 least, the mandatory must be configured.
457 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
459 * Added HMAC list to the SKE proposal list. It has now both
460 hash algorithm list and HMAC list. This makes the protocol
461 incompatible with previous versions. The SKE now seems to work
462 the way it is supposed to work, for the first time actually.
464 * Defined plain Hash algorithms to the protocol specification.
467 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
469 * Implemented support for key agreement packets into the server.
470 Added functions silc_server_key_agreement and
471 silc_server_send_key_agreement. Other than these functions,
472 server has nothing to do with this packet.
474 * Added support for private message key packets into the server.
475 Added functions silc_server_private_message_key and
476 silc_server_send_private_message_key.
480 * Changed the silc_[client|server]_protocol_ke_set_keys to be
481 called in the protocol's final callback instead in the END
482 protocol state. This makes a little more sense and in the same
483 time in client we can use the same protocol routines for normal
484 key exchange and to key agreement packet handling as well.
486 * Added to both client's and server's KE protocol context the
487 SilcSKEKeyMaterial pointer to save the key material. We will
488 bring the key material to the protocol's final callback by doing
489 this. The final callback must free the key material.
491 * Added SKE's packet_send callback into client's KE protocol
492 context so that the caller can choose what packet sending function
493 is used. This way we can use different packet sending when
494 doing normal SKE when doing key agreement packet handling (in
495 the key agreement packet handling we do not want to encrypt
498 * Implemented the responder side of the key agreement routines
499 in the client. The client can now bind to specified port and
500 accept incoming key negotiation. The key material is passed
501 to the application after the protocol is over.
503 * Implemented the processing of incoming Key Agreement packet
504 in the client. Added function silc_client_key_agreement to
507 * Implemented the intiator side of the key agreement routines
508 in the client. The client can now initiate key agreement with
509 another remote client. The key material is passed to the
510 application after the protocol is over.
512 * Created client_keyagr.c to include all the key agreement
515 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
516 SILC_TASK_CALLBACK except that it is not static.
518 * Created client_notify.c and moved the Notify packet handling
519 from the client.[ch] into that file.
521 * Created client_prvmsg.c and moved all private message and
522 private message key routines from the client.[ch] into that file.
524 * Create client_channel.c and moved all channel message and
525 channel private key routines from the client.[ch] into that file.
527 * Changed silc_client_get_client_by_id_resolve to resolve with
528 WHOIS command instead of IDENTIFY command, in the file
529 lib/silclient/idlist.c.
531 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
533 * Implemented the SKE's responder side to the Client library.
535 * When FAILURE is received to the protocol do not trust it
536 blindly. Register a timeout to wait whether the remote closes
537 the connection as it should do it, only after that process the
538 actual failure. This was changed to both client and server.
540 * Added client_internal.h to include some of the structures
541 there instead of client.h in lib/silcclient/.
543 * Added function silc_task_unregister_by_callback to unregister
544 timeouts by the callback function.
546 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
548 * Some "Incomplete WHOIS info" errors has been appearing on the
549 log files. Took away the entry->userinfo check from WHOIS
550 reply sending. The entry->userinfo is now " " if client did not
551 provide one. I thought this was fixed earlier but something
552 is wrong still. Let's see if the error still appears.
554 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
556 * Fixed a minor bug in the login when the channel key is
557 re-generated in the server. It used to generate the key in
558 wrong order and thus caused problems in the channel traffic.
560 * Fixed a minor bug in channel key distsribution after
561 KICK command. The key was not sent to the router even though
564 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
566 * Added silc_ske_process_key_material_data as generic routine
567 to process any key material as the SILC protocol dictates. The
568 function is used by the actual SKE library but can be used by
569 applications as well. This relates to the private message keys
570 and the channel private keys since they must be processed the
571 same way the normal SILC session keys. The protocol dictates
572 this. Affected files: lib/silcske/silcske.[ch].
574 Added also silc_ske_free_key_material to free the
575 SilcSKEKeyMaterial structure.
577 * Defined silc_cipher_set_key function to set the key for
578 cipher without using the object's method function. The affected
579 files: lib/silccrypt/silccipher.[ch].
581 * Implemented silc silc_client_add_private_message_key,
582 silc_client_add_private_message_key_ske,
583 silc_client_del_private_message_key,
584 silc_client_list_private_message_keys and
585 silc_client_free_private_message_keys functions in the
588 Added functions silc_client_send_private_message_key to send
589 the Private Message Key payload and silc_client_private_message_key
590 to handle incoming Private Message Key payload.
592 * Added Cipher field to the Private Message Key payload to set
593 the cipher to be used. If ignored, the default cipher defined
594 in the SILC protocol (aes-256-cbc) is used.
596 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
598 * Removed lib/silcclient/ops.h file.
600 Redefined parts of the SILC Client Library API. Created new
601 file silcapi.h that deprecates the ops.h file and defines the
602 published Client Library API. Defined also private message key
603 API and channel private key API into the file.
605 This is the file that the application must include from the
606 SILC Client Library. Other files need not be included by
607 the application anymore.
609 * Added new key_agreement client operation callback and also
610 defined the Key Agreement library API for the application.
612 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
614 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
615 is used by clients to request key negotiation between another
616 client in the SILC network. If the negotiation is started it
617 is performed using the SKE protocol. The result of the
618 negotiation, the secret key material, can be used for example
619 as private message key.
621 Implemented the Key Agreement payload into the files
622 lib/silccore/silauth.[ch].
624 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
626 * Redefined ciphers for the SILC protocol. Added some new ciphers
627 and defined the key lengths for the algorithms. Changed the
628 code accordingly. The default key length is now 256 bits.
630 * Fixed SKE key distribution function silc_ske_process_key_material
631 when the key length is more than 128 bits. The default key
632 length in SILC is now 256 bits.
634 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
635 to indicate unsupported algorithm.
637 * Renamed rijndael.c to aes.c and all functions as well.
639 * Fixed a long standing channel key setting bug in client library.
640 Weird that it has never surfaced before.
642 * Fixed bug in channel deletion. If the entire channel is removed
643 then it must also delete the references of the channel entry
644 from the client's channel list as the client's channel entry and
645 the channel's client entry share same memory.
647 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
649 * Implemented CONNECT and SHUTDOWN commands in the client.
651 * Implemented CLOSE command to the client.
653 * Added the function silc_idlist_find_server_by_name into the
654 files silcd/idlist.[ch].
656 Added the function silc_idlist_find_server_by_conn into the
657 files silcd/idlist.[ch].
659 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
661 * DIE command was renamed to SHUTDOWN. Updated the both code
664 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
665 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
667 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
670 * Added function silc_server_create_connection function to create
671 connection to remote router. My server implementation actually
672 does not allow router to connect to normal server (it expects
673 that normal server always initiates the connection to the router)
674 so the CONNECT command is only good for connecting to another
677 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
679 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
680 or some other client was kicked from the channel.
682 Implemented the handling of the notify type to both client
685 Implemented silc_server_send_notify_kicked to send the KICKED
686 notify. It is used to send it to the server's primary router.
688 * Implemented the KICK command into server and client.
690 * Added `query' argument to the silc_idlist_get_client function
691 to indicate whether to query the client from server or not if
694 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
695 to indicate that the client is not channel founder.
699 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
701 * Removed the rng context from SilcPacketContext structure and
702 changed that the packet routine uses the Global RNG API.
704 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
706 * Added support for quit message that client can "leave" on the
707 channel when it quits the SILC. It is ditributed inside the
708 SILC_NOTIFY_TYPE_SIGNOFF notify type.
710 Added silc_server_free_client_data that will take the
711 signoff message as argument.
713 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
715 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
717 * Updated parts of the protocol specification to keep it up
720 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
723 payloads in one packet.
725 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
726 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
727 use now the new List flag.
729 * Also deprecated the following packet types: REPLACE_ID,
730 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
732 * Added list support for Notify packet in server.
734 * Added silc_server_send_notify_channel_change to send the
735 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
736 the silc_server_send_replace_id.
738 * Added silc_server_send_notify_nick_change to send the
739 NICK_CHANGE notify type. Deprecates the function
740 silc_server_send_replace_id.
742 * Added silc_server_send_notify_join to send the JOIN notify type.
743 Deprecates the function silc_server_send_new_channel_user.
745 * Added silc_server_send_notify_leave to send LEAVE notify type.
746 Deprecates the function silc_server_send_remove_channel_user.
748 * Added silc_server_send_notify_cmode and
749 silc_server_send_notify_cumode to send CMODE and CUMODE notify
750 types. Deprecates the silc_server_send_set_mode function.
752 * Added SERVER_SIGNOFF notify type to indicate that server has
753 quit. This means that all clients on the channel from that
754 server will drop. This can be also used when netsplit happens.
756 Deprecated REMOVE_ID packet type since it is not needed anymore
759 Added silc_server_send_notify_server_signoff to send the
760 SERVER_SIGNOFF notify type. Deprecates the function
761 silc_server_send_remove_id.
763 Added also silc_server_send_notify_signoff to send the
766 * Employed the PKCS #1. It is the mandatory way to do RSA in the
767 SILC protocol from this day on. Changed the protocol
768 specification as well.
770 * Added silc_server_send_notify_topic_set to send TOPIC_SET
771 notify type. It is used between routers to notify about
772 topic changes on a channel.
774 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
777 * Partly updated the protocol specification to comply with the
778 changes now made. It is still though a bit outdated.
780 * The JOIN notify type now takes one extra argument <Channel ID>.
781 The packet used to be destined to the channel but now the
782 JOIN type may be sent as list thus it is impossible to
783 destine it to any specific channel. By adding this argument
784 it is again possible.
786 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
788 * Added CREDITS file. The CHANGES and CREDITS file will appear
789 in the distribution as well.
791 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
793 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
794 types in the server's silcd/packet_receive.c.
796 * Implemented CMODE and CUMODE to work in router environment.
798 * Fixed minor encoding and decoding buglet from the
799 lib/silccore/silcmode.c.
801 * Fixed buffer overflow from lib/silcclient/command.c in USERS
804 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
806 * Changed all SilcConfigServer* and silc_config_server* to
807 SilcServerConfig* and silc_server_config*, respectively.
810 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
812 * Associated the ID (client or server ID) to the Authentication
813 Payload to avoid any possibility of forging. Updated the
814 protocol specification and the code accordingly.
816 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
818 * The RSA key length is now save to the RsaKey context in the
819 key generation process in lib/silccrypt/rsa.c. The key length
820 is now used to figure out the maximum size of the block allowed
821 to be encrypted/signed.
823 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
824 is equivalent to the silc_mp_mp2bin but does not allocate any
827 * Changed silc_mp_mp2bin API to take length argument. If it is
828 non-zero then the buffer is allocated that large. If zero, then
829 the size is approximated using silc_mp_sizeinbase, which however
832 * Created Global RNG API which is global RNG that application can
833 initialize. After initializing, any routine anywhere in the
834 code (including library) can use RNG without allocating a new
835 RNG object. This was done to allow this sort of use of the
836 RNG in code that has no chance to allocate RNG object. All
837 applications currently allocate this and many routines in the
838 library use this. Affected file lib/silccrypt/silcrng.[ch].
840 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
841 it to use the Global RNG API.
843 * Defined Authentication Payload into protocol specification that
844 is used during SILC session to authenticate entities. It is
845 used for example by client to authenticate itself to the server
846 to obtain server operator privileges.
848 Implemented this payload into the lib/silccore/silcauth.[ch].
849 Implemented also routines for public key based authentication
850 as the new protocol specification dictates.
852 Moved definitions of different authentication methods from
853 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
855 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
856 silc_pkcs_verify and silc_pkcs_sign_with_hash and
857 silc_pkcs_verify_with_hash functions into the file
858 lib/silccrypt/silcpkcs.[ch].
860 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
862 * The client entry's userinfo pointer must be always valid.
863 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
864 will fail since it requires the userinfo. Now, the userinfo
865 is allocated as "" if actual userinfo does not exist. Actually,
866 it must exist and it is totally Ok to drop client connections
867 that does not announce the userinfo. However, we will make
868 this workaround for now.
870 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
871 to return the remote port by socket.
873 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
875 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
876 SILC_SERVER_PENDING_EXEC and added an new macro
877 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
878 data or when error occurs while processing the pending command.
880 Added new argument `destructor' into silc_server_command_pending
881 and to the SilcServerCommandPending object. This destructor is
882 now called after calling the pending callback or if error occurs
883 immediately. If error occurs the actual pending callback won't
884 be called at all - only the destructor. The destructor may be
885 NULL if destructor is not needed.
887 All this applies for client library code as well. Similar
888 changes were made there as well for the pending commands.
890 In the client, the application must now allocate the
891 SilcClientCommandContext with the silc_client_command_alloc
894 * Added reference counter to the SilcServerCommandContext. Added
895 function silc_server_command_alloc and silc_server_command_dup
898 Same type of functions added to the client library for the same
901 * Removed the cmd_ident from IDListData away since it is now
902 global for all connections. It is the command identifier used
903 in command sending and with pending commands. The affected file
906 * Added reference counter to the SilcSocketConnection objecet to
907 indicate the usage count of the object. The object won't be
908 freed untill the reference counter hits zero. Currently only
909 server uses this, and client ignores it. The client must be
910 set to use this too later. The affected files are
911 lib/silccore/silcsockconn.[ch]. Added also the function
912 silc_socket_dup to increase the reference counter.
914 This was mainly added because it is possible that the socket
915 is removed underneath of pending command or other async
916 operation. Now it won't be free'd and proper DISCONNECTING
917 flags, etc. can be set to avoid sending data to connection that
918 is not valid anymore.
920 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
921 the connection. After that it sets SILC_SET_DISCONNECTED.
922 It is, however, possible that the socket data is not still freed.
923 The silc_server_packet_process now checks that data is not
924 read or written to connection that is DISCONNECTED. The socket
925 get's freed when the reference counter hits zero.
927 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
929 * Changed the client operation API: channel_message operation's
930 `sender' is now the client entry of the sender, not the nickname
931 and the `channel' is the channel entry, not the channel name.
933 In the private_message operation the `sender' is now also the
934 client entry of the sender not the nickname.
936 Affected file is lib/silcclient/ops.h and all applications
937 using the client operations.
939 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
941 * Moved the calling of ops->connect() from connect_to_server_final
942 into receive_new_id functin since that is the point when the
943 client is actually allowed to send traffic to network. The
944 affected file is lib/silcclient/client.c.
946 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
948 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
949 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
950 (if needs broadcasting) instead of broadcasting the packets one
951 by one which would make a burst in the network traffic.
953 * Added `broadcast' argument to the functions in silcd/server.[ch]
954 silc_server_create_new_channel[_with_id] to indicate whether
955 to send New Channel packet to primary router.
957 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
959 * Added new function into the silcd/server.[ch] files:
960 silc_server_create_new_channel_with_id to create new channel with
961 already existing Channel ID.
963 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
964 lib/silccore/silcpacket.h. This packet is used t send list of
965 Set Mode payloads inside one packet. Server uses this to set
966 the modes for the channels and clients on those channels, that it
967 announced to the router when it connected to it. The protocol
968 specification has been updated accordingly.
970 * The silc_server_new_channel did not handle the packet coming
971 from normal server as it normally does not send that. However,
972 when it announces its channels it does send it. Implemented
973 the support for that.
975 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
976 into the file lib/silccore/id.h.
978 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
980 * Fixed memory leaks in the functions silc_idlist_del_client,
981 silc_idlist_del_channel and silc_idlist_del_server in the file
982 silcd/idlist.c. All of those leaked like a sieve.
984 * Fixed some small memory leaks in the client's function
985 silc_client_notify_by_server.
987 * Added functions into silcd/server.c: silc_server_announce_clients,
988 silc_server_announce_channels and silc_server_announce_server.
989 These functions are used by normal and router server to announce
990 to its primary router about clients, channels and servers (when
991 router) that we own. This is done after we've connected to the
994 These functions effectively implements the following packet types:
995 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
996 and SILC_PACKET_NEW_ID_LIST.
998 * Added new functions into the silcd/packet_receive.[ch]:
999 silc_server_new_id_list, silc_server_new_channel_list and
1000 silc_server_new_channel_user_list to handle the incoming
1001 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1003 * Added support of changing Channel ID in the function
1004 silc_server_replace_id. If the server that announces a channel
1005 to the router already exists in the router (with same name but
1006 with different Channel ID), router is responsible to send
1007 Replace ID packet to the server and force the server to change
1008 the Channel ID to the one router has.
1010 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1011 client that the Channel ID has been changed by the router. The
1012 normal server sends this to the client. Client must start using
1013 the new Channel ID as the channel's ID.
1015 Implemented handling of this new type into lib/silcclient/client.c
1016 into the function silc_client_notify_by_server.
1018 * Added new function silc_idlist_replace_channel_id into the files
1019 silcd/idlist.[ch] to replace the Channel ID.
1021 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1023 * Call silc_server_command_identify_check always when processing
1024 the IDENTIFY command in silcd/command.c
1026 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1028 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1029 send keepalive packets. The packet can be sent by clients,
1030 servers and routers.
1032 Added function silc_socket_set_heartbeat into the file
1033 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1034 If not set, the heartbeat is not performed. The actual
1035 heartbeat is implemented in the low level socket connection
1036 library. However, application is responsible of actually
1039 Added silc_server_send_heartbeat to send the actual heartbeat
1040 packet into silcd/packet_send.[ch]. Server now performs
1041 keepalive with all connections.
1043 * Added silc_task_get_first function into lib/silcutil/silctask.c
1044 to return the timeout task with shortest timeout. There was a bug
1045 in task unregistration that caused problems. TODO has been
1046 updated to include that task system must be rewritten.
1048 * The client library will now resolve the client information when
1049 receiving JOIN notify from server for client that we know but
1050 have incomplete information.
1052 * Rewrote parts of silc_server_remove_from_channels and
1053 silc_server_remove_from_one_channel as they did not remove the
1054 channel in some circumstances even though they should've.
1056 * Encryption problem encountered in server:
1058 The LEAVE command used to send the Channel Key packet to the
1059 router immediately after generating it. However, the code
1060 had earlier sent Remove Channel user packet but not immediately,
1061 ie. it was put to queue. The order of packets in the router
1062 was that Channel Key packet was first and Remove Channel User
1063 packet was second, even though they were encrypted in the
1064 reverse order. For this reason, MAC check failed. Now, this
1065 is fixed by not sending the Channel Key packet immediately but
1066 putting it to queue. However, this is more fundamental problem:
1067 packets that are in queue should actually not be encrypted
1068 because packets that are sent immediately gets encrypted
1069 actually with wrong IV (and thus MAC check fails). So, packets
1070 that are in queue should be encrypted when they are sent to
1071 the wire and not when they put to the queue.
1073 However, the problem is that the current system has not been
1074 designed to work that way. Instead, the packet is encrypted
1075 as soon as possible and left to the queue. The queue is then
1076 just purged into wire. There won't be any fixes for this
1077 any time soon. So, the current semantic for packet sending
1080 o If you send packet to remote host and do not force the send
1081 (the packet will be in queue) then all subsequent packets to the
1082 same remote host must also be put to the queue. Only after the
1083 queue has been purged is it safe again to force the packet
1086 o If you send all packets immediately then it safe to send
1087 any of subsequent packets through the queue, however, after
1088 the first packet is put to queue then any subsequent packets
1089 must also be put to the queue.
1091 Follow these rules and everything works fine.
1093 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1095 * Added new function silc_server_remove_clients_by_server to
1096 remove all client entries from ID list when the server connection
1097 is lost. In this case it is also important to invalidate all
1098 client entires as they hold the invalid server entry. This
1099 fixes fatal bug when server has lost connection and will reconnect
1102 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Made some sanity checks to silc_server_daemonise like to check
1105 whether the requested user and group actually exists.
1107 * Added sanity check to SKE's silc_ske_responder_finish to check
1108 that the public and private key actually is valid.
1110 * Invalidate the client's nickname when receiving Replace ID
1111 packet and the Client ID is being replaced. This means that the
1112 server will query the nickname if someone needs it (client)
1115 * Sort the ID Cache in client library when the ID Cache data
1116 has changed (needs sorting).
1118 * Do not allow for SILC client to create several connections to
1119 several servers. The client does not support windows right now
1120 and generating multiple connections causes weird behaviour.
1122 Irssi-silc client does support windows and can handle several
1123 connections without problems, see: www.irssi.org and SILC plugin.
1125 * Fixed some places where client was added to the IDList. The
1126 rule of thumb is following (in order to get everything right):
1127 If the client is directly connected local client then the
1128 `connection' argument must be set and `router' argument must be
1129 NULL to silc_idlist_add_client function. If the client is not
1130 directly connected client then the `router' argument must
1131 bet set and the `connection' argument must be NULL to the
1132 silc_idlist_add_client function.
1134 * The funtion silc_server_packet_send_local_channel actually did
1135 not check whether the client was locally connected or not. It
1136 does that now. Fixed a bug related to LEAVE command.
1138 * Fixed Remove Channel User payload parsing bug in server's
1139 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1141 * The server's silc_server_save_channel_key now checks also the
1142 global ID list for the channel as it might not be in the local
1143 list. Fixed a bug related to LEAVE command.
1145 * Is this the end of the [<unknown>] buglet that has been lurking
1146 around for a long time? A little for loop fix in server's
1147 silc_server_command_whois_parse that is used by both IDENTIFY
1148 and WHOIS command. At least, this was a clear bug and a cause
1149 of one type of [<unknown>] buglet.
1151 * WHOIS and IDENTIFY commands call the function
1152 silc_server_command_[whois/identify]_check function even if
1153 we are not router server.
1155 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1157 * Added --with-gmp configuration option. If set the GMP
1158 is always compiled in the SILC source tree. If not set then
1159 it is checked whether the system has the GMP3 installed. If
1160 it has then the GMP won't be compiled (the system's headers
1161 and library is used), if it doesn't have it then the GMP is
1162 compiled in the SILC source tree.
1164 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1166 * Changed RSA private exponent generation to what PKCS #1
1167 suggests. We try to find the smallest possible d by doing
1168 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1169 not security fix but optimization.
1171 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1173 * Added new config entry [Identity] to fork the server and run
1174 it as specific user and group. A patch from Bostik.
1176 * Imported Dotconf configuration library into lib/dotconf.
1177 This will be used to create the SILC configuration files later.
1178 It will appear in the distsribution after this commit.
1180 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * A big code auditing weekend happening. Auditing code for
1183 obvious mistakes, bugs and errors. Also, removing any code
1186 Removed files for being obsolete:
1188 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1189 inline in the file lib/silcutil/silcbuffer.h)
1191 o lib/silcutil/silcbufutil.c (the header has inline versions)
1193 Changed code to fix possible error conditions:
1195 o The buffer formatting routines now check that the destination
1196 buffer really has enough space to add the data. This applies for
1197 both buffer formatting and unformatting
1198 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1199 unformatting was changed to accomodate following rules:
1200 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1201 sent to the function while XXX_*STRING will not allocate or copy
1202 the data into the buffer. Instead it sets the pointer from the
1203 buffer into the pointer sent as argument (XXX_*STRING used to
1204 require that the pointer must be allocated already). This change
1205 makes this whole thing a bit more consistent and more optimized
1206 (note that the data returned in the unformatting with XXX_*STRING
1207 must not be freed now). The routines return now -1 on error.
1209 o Tried to find all code that use buffer_format and buffer_unformat
1210 and added return value checking to prevent formatting and
1211 especially unformatting errors and possible subsequent fatal
1214 o Changed ske->x and ske->KEY to mallocated pointers in
1215 lib/silcske/silcske.h. Fixed possible data and memory leak.
1217 o Added return value checking to all *_parse* functions. Fixed
1218 many memory leaks as well.
1220 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1221 so that buffer overflows would not happen. All code now also
1222 checks the return value as it can fail.
1224 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1226 * Added reconnection support to server if the normal server looses
1227 its connection to the router (for example if router is rebooted).
1228 The server performs normal reconnection strategy implemented
1229 to the server. Affected file silcd/server.c.
1231 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1233 * Added new packet type SILC_PACKET_SET_MODE that is used to
1234 distribute the information about changed modes (for clients,
1235 channels and clients channel modes) to all routers in the
1236 network. Updated the protocol specification accordingly.
1238 Added functions into silcd/packet_send.c and
1239 silcd/packet_receive.c: silc_server_send_set_mode,
1240 silc_server_set_mode.
1242 Added new files silcmode.[ch] into lib/silccore that implements
1243 the encoding and decoding of Set Mode Payload. Added new type
1244 SilcSetModePayload. Moved the definitions of different modes
1245 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1247 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1249 * Oops, a little mistake in server's connection authentication
1250 protocol. The protocol is not ended with FAILURE but with
1251 SUCCESS if the authentication is Ok. :) Affected file is
1254 * Implemented NICK_CHANGE notify handling in server in the file
1255 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1256 the local clients on the channel. After the changing nickname
1257 in router environment snhould work and the [<unknown>] nickname
1258 should appear no more.
1260 The silc_server_replace_id function that receives the Replace ID
1261 payload now sends the NICK_CHANGE notify type also in the file
1262 silcd/packet_receive.c
1264 * Changed WHOIS and IDENTIFY command to support the maximum amount
1265 of arguments defined in protocol specs (3328 arguments). This
1266 fixed a bug that caused problems when there were more than three
1269 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1271 * Added extra parameter, command identifier, to the
1272 silc_client_send_command so that explicit command identifier
1275 Changed that ID list routines uses specific command identifier
1276 when sending WHOIS/IDENTIFY requests to the server so that they
1277 can be identified when the reply comes back.
1279 Affected files lib/silcclient/command.[ch],
1280 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1282 * Added `sender' argument to silc_server_packet_send_to_channel
1283 to indicaet the sender who originally sent the packet to us
1284 that we are now re-sending. Ignored if NULL. Affected file
1285 silcd/packet_send.[ch].
1287 * Added some server statistics support in silcd/server_internal.h
1288 SilcServerStatistics structure and around the server code. Also
1289 send some nice statistics information when client is connecting
1292 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1294 * Fixed channel ID decoding in server's JOIN command reply in
1295 silcd/command_reply.c
1297 * Fixed braodcasting of replace ID payload to not to send it if
1298 we are standalone server in silcd/packet_receive.c.
1300 * Fixed all channel message sending routines to not to send
1301 packets to clients that has router set, since they are routed
1302 separately in the same function earlier. Affects file
1303 silcd/packet_send.c and all channel packet sending functions.
1305 * In USERS reply, res_argv[i] are not allocated, the table
1306 is allocated. Thus changed that free the table, not its
1309 * In server's whois_check and identify_check if the client is
1310 locally connected do not send any WHOIS commands - they are not
1313 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1315 * Fixed some minor bugs in client when sending WHOIS command. The
1316 arguments was in wrong order.
1318 * Removed statis function add_to_channel from server in
1319 silcd/command.c that was previously used with the joining but
1322 * Tested USERS command in router environment successfully with two
1323 routers, two servers and two clients.
1325 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1327 * Reorganized the USERS command and command reply in client library
1328 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1329 When the command is given by user we register a pending command
1330 callback that will reprocess the command after the reply has been
1331 received from the server. When reprocessing the packet we then
1332 display the information. Thus, the USERS information is displayed
1333 now in the command callback instead of in the command reply
1334 callback. The processing of the command is same as previously
1335 when server has sent the command reply in the JOINing process.
1337 * Added to USERS command in silcd/command_reply.c to join the client,
1338 we didn't use to know about, to the channel after we've created
1339 a client entry for it. Also, for clienet we did know already still
1340 check whether it is on the channel or not and add it if not.
1342 * Removed silc_server_command_join_notify as the function and its
1345 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1347 * Changed the client's pending command handling to the same as the
1348 server's pending command handling. It is also now possible to
1349 execute command reply functions from other command reply
1350 function as the function callbacks for commands and command
1351 replies are one and same. The pending commands are not static
1352 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1353 in client connection context. Thus, pending commands are server
1354 connection specific as it is convenient.
1356 Changed the function silc_client_command_pending and
1357 silc_client_command_pending_del and added new function
1358 silc_client_command_pending_check. Removed the
1359 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1362 * Added cmd_ident, current command identifier, to the client
1363 connection context in lib/silcclient/client.h to keep track on
1364 command identifiers used in command sending. Client's command reply
1365 function handling now supports the mandatory command identifiers.
1367 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1368 funtions in client to fully support pending command callbacks.
1370 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1371 as one of the arguments to the application in the command reply
1374 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1375 before first releasing SILC but came back. Now it is removed again
1376 and should come back nomore. The FORWARDED flag was used only
1377 by the JOINing procedure by forwarding the command packet to router.
1378 Now, the JOINing procedure has been changed to more generic (due
1379 to various router environment issues) and FORWARDED is not needed
1380 anymore for anything. The protocol specification is yet to be
1383 Now, removed silc_server_packet_forward from server and the flag
1384 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1386 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Renamed NAMES command to USERS command. The NAMES was named that
1389 due to historical reasons. Now it is renamed. Also, rewrote
1390 parts of the USERS command. The nickname list is not sent anymore
1391 by the server. Only Client ID and mode lists are sent in the USERS
1392 command. Changed this also to the protocol specification.
1394 The client now resolves the names and stuff after it receives
1395 the USERS list from the server when joining to the channel.
1397 * WHOIS and IDENTIFY commands has been changed to support multiple
1398 Client ID's per command. One can now search for multiple users
1399 in the network by sending only one WHOIS or IDENTIFY command.
1400 Changed the code and the protocol specifications.
1402 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1403 uses silc_server_command_whois_parse to parse the request. */
1405 * If normal server, do not parse the WHOIS and IDENTIFY requests
1406 before sending it to the router. Saves some time.
1408 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1410 * Fixed JOIN command on client library. Wrong number of arguments
1411 used to crash the client.
1413 * Added silc_server_channel_has_global function to check whether
1414 channel has global users or not.
1416 * Added silc_server_channel_has_local function to check whether channel
1417 has locally connected clients on the channel.
1419 * The silc_server_remove_from_one_channel now checks whether the
1420 channel has global users or not after given client was removed from
1421 the channel. It also checks whether the channel has local clients
1422 on the channel anymore. If it does not have then the channel entry
1423 is removed as it is not needed anymore.
1425 * The silc_server_notify now checks on JOIN notify whether the joining
1426 client is one of locally connected or global. If it is global then
1427 the channel has now global users on the channel and that is marked
1428 to the channel entry. Also, it now saves the global client to
1429 global list who is joining and JOINs it to the channel. This is
1430 for normal server, that is.
1432 Changed silc_server_send_notify_on_channel,
1433 silc_server_packet_relay_to_channel and
1434 silc_server_packet_send_to_channel check if we are normal server
1435 and client has router set (ie. global client) do not send the
1436 message to that client, as it is already routed to our router.
1438 * Implemented LEAVE notify type handling in silc_server_notify
1441 * Tested LEAVE command in router environment successfully. Tested
1442 with two routers, two servers and two clients.
1446 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1448 * Implemented SIGNOFF notify type handling in silc_server_notify
1451 * silc_server_remove_id now removes the client entry from all channels
1452 it has joined and thusly sends SIGNOFF notify type.
1454 * Rewrote the NAMES list generation in server by removing two excess
1455 loops. The lists are created now inside one loop.
1457 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1459 * silc_server_remove_channel_user checks now also global list
1460 for channel and client.
1462 * silc_server_new_channel_user checks now both local and global
1463 list for channel and client. Fixed a bug in client id decoding.
1464 Used to decode wrong buffer.
1466 * silc_server_channel_message checks now both local and global
1467 list for channel entry.
1469 * Tested channel joining (hence JOIN) in router environment
1470 successfully. Tested with two routers, two servers and two
1473 * Tested channel message sending in router environment successfully.
1475 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1477 * Added silc_server_save_channel_key into server.[ch] to save the
1478 received channel key in Channel Key payload processing. It is
1479 also used in JOIN command reply handling.
1481 Equivalent function silc_client_save_channel_key added into
1482 client.[ch] into client library.
1484 * Changed JOIN command reply to send information whether the channel
1485 was created or not (is existing already) and the channel key
1486 payload. Changed protocol specs accordingly.
1488 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1489 the request was sent by ID and not by nickname. Crashed on
1492 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1494 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1495 now correctly save the received data.
1497 * silc_server_free_sock_user_data now notifies routers in the
1498 network about entities leaving the network.
1500 At the same time implemented functions silc_server_remove_id
1501 and silc_server_send_remove_id to receive and send REMOVE_ID
1502 packets. The packet is used to notify routers in the network
1503 about leaving entities. The ID removed will become invalid in
1506 * Added function silc_idlist_del_server into server. Removes and
1507 free's server entry from ID list.
1509 * silc_server_private_message function now checks, if we are router,
1510 that the destination ID really is valid ID, naturally.
1512 * In router when NEW_ID packet is received (for new client) the
1513 hash of the Client ID is saved in the ID Cache but the
1514 client->nickname is set to NULL, instead of putting the hash
1517 IDENTIFY command now also checks that client->nickname must be
1518 valid. If it is not if will request the data from the server who
1519 owns the client. Added new function
1520 silc_server_command_identify_check.
1522 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1523 to set the command to already allocated Command Payload.
1525 * Tested private message sending in router environment with two
1526 routers, two servers and two clients. Fixed minor bugs and now
1529 * Fixed segfault from client's NAMES command. Used to crash if
1532 * Forwarded packets must not be routed even if it is not destined
1533 to the receiver. Changed server code comply with this.
1535 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1537 * Added `require_reverse_mapping' boolean value to ServerParams
1538 structure. If TRUE (not default) the server will require that
1539 the connecting host has fully qualified domain name.
1541 If the reverse mapping is not required and hostname could not be
1542 found the IP address is used as hostname.
1544 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1546 * Implemented version string checking to both client and server.
1547 The check is incomplete currently due to the abnormal version
1548 strings used in development version of SILC.
1550 * Changed all command functions in server to use the new
1553 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1555 * Changed char *data to unsigned char *data in ID Cache system to
1556 support binary data as ID Cache data. Changed code to support
1557 binary data in lib/silccore/idcache.c.
1559 * Renamed silc_server_packet_relay_command_reply to
1560 silc_server_command_reply as it is normal packet receiving
1561 function. Rewrote the function to accept command replys for
1562 servers and not only for clients.
1564 * Mark remote router always as registered server if we are connecting
1565 to it. Otherwise, commands sent by the router to us are ignored.
1567 * All ID List find routines now returns the ID Cache Entry pointer
1568 as well if requested.
1570 * WHOIS command works now in router environment, tested with two
1571 routers, two servers and two clients.
1573 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1574 in router environment (as it is almost equivalent to WHOIS) but
1575 hasn't been tested thoroughly. Added new functions:
1577 silc_server_command_identify_parse
1578 silc_server_command_identify_send_reply
1579 silc_server_command_identify_from_client
1580 silc_server_command_identify_from_server
1582 * Disabled route cache adding because adding two different ID's with
1583 same IP replaces the old cache entry thus giving wrong route.
1584 The entry->router->connection is always the fastest route anyway
1585 so route cache may not be needed. Of course, new routes maybe
1586 established after receiving the ID when the entry->router->connection
1587 might not be anymore the most optimal.
1589 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1591 * Add route cache for received ID for fast routing.
1593 * Added silc_server_packet_route to route received packet on router
1594 that is not destined to us.
1596 * Renamed silc_server_get_route to silc_server_route_get.
1598 * Added id_string and id_string_len fields into SilcServer to
1599 include encoded ServerID for fast comparing without excess
1600 encoding of the ID's.
1602 * Cleaned up WHOIS command on server side. Added following static
1605 silc_server_command_whois_parse
1606 silc_server_command_whois_check
1607 silc_server_command_whois_send_reply
1608 silc_server_command_whois_from_client
1609 silc_server_command_whois_from_server
1611 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1612 arguments in command replies. All command functions should be
1613 updated to use this macro.
1615 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1617 * Minor typo fixes on command reply handling on server.
1619 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1621 * Added silc_server_command_add_to_channel internal routine to add
1622 the client to the channel after router has created the channel and
1623 sent command reply to the server.
1625 * Added generic silc_server_send_command to send any command from
1628 * Use static buffer with ID rendering instead of duplicating data.
1630 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1632 * Fixed a channel user mode bug when joining to a channel server gave
1633 everybody channel founder rights, oops.
1635 * We mark ourselves as the router of the incoming server connection
1636 if we are router ourselves. This way we can check in some packet
1637 sending functions whether it is locally connected server. For
1638 incoming router connections we put NULL.
1640 * For router sending packets locally means now always sending the
1641 packet cell wide; to local clients and local servers. For normal
1642 server sending packet locally means sending it to only local
1645 * Fixed the JOIN command to really work in router environment. If the
1646 channel is created it is always created by the router. Router is
1647 also responsible of making the initial joining to the channel,
1648 sending JOIN notify to the sending server and distributing
1649 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1650 does not exist server doesn't do anything else but forward the
1651 command to the router which performs everything.
1653 * Added silc_server_send_channel_key function to send the Channel Key
1656 * Added silc_server_create_channel_key to create new channel key. The
1657 channel key is now re-generated everytime someone joins or leaves
1658 a channel, as protocol dictates. Note: channel->key_len is the
1661 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1663 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1664 packet_receive.[ch] to separate packet sending and receiving
1665 routines. The server.[ch] now includes everything else including
1666 actual packet processing (writing and reading data) and other
1669 Renamed silc_server_private_message_send_internal to
1670 silc_server_send_private_message. The routine is still though
1671 used only to relay private messages as server does not send
1672 private messages itself.
1674 Renamed silc_server_new_channel to silc_server_create_new_channel
1675 and added new function sicl_server_new_channel that handles the
1676 incoming New Channel packet. Added also new sending function
1677 silc_server_send_new_channel to send New Channel Payload.
1679 * Added new function silc_server_notify to process incoming notify
1680 packet to the server/router. Server may then relay the notify
1681 to clients if needed.
1683 * Added new function silc_server_new_channel_user to process incoming
1684 New Channel User packet. Router will redistribute the packet and
1685 send JOIN notify to its local clients and locally connected servers
1686 if needed. Normal server will send JOIN notify to its local client
1687 on same channel when received this packet. Added also corresponding
1688 sending function silc_server_send_new_channel_user to sent the
1691 * Added boolean route argument to send_notif_to_channel and
1692 packet_send_to_channel functions to attempt to route the packet
1693 if it is TRUE and send only locally if it is FALSE.
1695 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1697 * silc_server_replace_id now broadcasts the received replace ID
1698 packet if it is not broadcast packet already. The router must
1699 broadcast to inform other routers about changed ID.
1701 * Added backpointer to server's router into SilcServer context in
1702 silcd/server_internal.h.
1704 * Fixed silc_server_packet_broadcast to send correct broadcast
1707 * The channel key is now distributed to the local client as soon
1708 as it is received from the router (in router environment) so that
1709 no other packet may be sent for the channel until client has
1712 * silc_server_remove_channel_user now broadcasts the received
1713 Remove Channel User packet if it is not broadcast packet already.
1714 The router must broadcast to inform other routers about removed
1717 * Added users field into SilcPacketContext that is a reference count
1718 of the context. One can increase the reference count by calling
1719 silc_packet_context_dup which is now changed to just increase the
1720 reference count instead of duplicating the data. The reference
1721 count is decresed by calling silc_packet_context_free that will
1722 free the data after the reference count hits zero.
1724 For now on the packet context and everything allocated into it
1725 (including the raw packet from network) must be freed by calling
1726 the new silc_packet_context_free function. Added also new function
1727 silc_packet_context_alloc that must be used now to allocate the
1728 context. This also means that if a routine is asynchronous from
1729 silc_[client/server]_packet_parse_type the packet context must
1730 be duplicated by calling silc_packet_context_dup. Otherwise it
1731 gets free'd after silc_[client/server]_packet_parse_type returns.
1732 Also, one must remember that if packet is duplicated then its
1733 reference count must be decresed by calling the free function as
1734 many times as it was duplicated.
1736 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1737 from both client and server.
1739 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1741 * Made joining to a channel working in router environment.
1743 * Cleaned up JOIN command on server side and create function
1744 silc_server_command_join_channel internal routine to make the
1747 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1749 * Changed silc_command_pending list to SilcDList. Also, added
1750 `ident' field to SilcServerCommandPending structure to identify
1751 the reply and to call correct callback.
1753 Added silc_server_command_pending_check function to replace the
1754 corresnponding macro. The silc_command_pending list is not
1757 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1758 to set identifier to previously allocated Command Payload. It
1759 is used to set identifier for command when resending Command
1762 * Added silc_command_payload_encode_payload to encode Command
1763 Payload buffer from SilcCommandPayload structure.
1765 * Added silc_argument_payload_encode_payload to encode Argument
1766 payload buffer from SilcArgumentPayload structure.
1768 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1770 * Changed WHOIS command to support router connection on server side.
1771 The whois request is always sent to router unless the server is
1772 standalone server. After server has received the reply from the
1773 router will it send the reply to the client.
1775 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1776 broadcast received broadcast packet. The function is used only
1777 by router. The broadcast packet is always sent to the router's
1780 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1781 render given ID to printable string, for log files for example.
1783 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1785 * Made basic router to router connections working. At least they
1786 can now connect to each other but nothing really works the way
1787 they are supposed - yet.
1789 * Added new initiator token to RouterConnection configuration
1790 file in silcd/serverconfig.[ch]. It is used to tell whether we
1791 are the initiator to the remote router or whether we'll expect
1792 the other end to connect.
1794 * Moved registering of listener task to silc_server_init, hence
1795 the server starts listenning as soon as it is run, even if it
1796 does not have connections to other routers. Let's see how well
1799 * Changed default connection retry timeouts for more suitable in
1802 * Removed cipher and such arguments from silc_idlist_add_client
1803 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1804 Added new function silc_idlist_add_data to add the keys and stuff
1807 * Added SilcIDListData structure and added it to SilcClientEntry
1808 and SilcServerEntry as their first field in the structure. This
1809 way we can explicitly cast the ID entries to the SilcIDListData
1810 structure and get common data for the entries. In past, we had
1811 to first check what type of connection it is and then cast it to
1812 correct ID entry type. Now, we can directly cast the opaque
1813 pointer to the SilcIDListData (no matter what ID entry it actually
1814 is) and get the data needed.
1816 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1818 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1819 in some circumstances even if threre were timeout tasks, though not
1820 IO tasks, but tasks anyway. Now fixed.
1822 * Defined SilcServerConnection structure to hold connection specific
1823 stuff about directly connected servers and routers. The definition
1824 is currently in silcd/server_internal.h. I thought about having
1825 a bit more important role fro this struct but for now it is used
1826 only when connecting to other server (or router actually).
1828 * Added connecting retry support in server when connecting to
1829 router(s). The retry feature implement exponential backoff
1830 algorithm. Also, added SilcServerParams structure to hold default
1831 parameters for server. For now, it include these retry settings
1832 and are hard coded. After server is moded to be as Silc Server
1833 Library this structure will be more important.
1835 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1837 * Changed client librarys channel->clients table to SilcList and
1838 changed code accordingly.
1840 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1842 * Changed client's channel table to SilcList and changed code
1843 accordingly. Also changed SilcChannelClientEntry to include back-
1844 pointer to the channel so that client entry can use that structure
1845 as list as well and we have fast cross-reference to the channel.
1846 This change dramatically decreased the complexity of channel
1847 handling with client entry and vice versa (removed one extra
1848 loop when searching for channel entry from many functions).
1850 * Changed server->sim from table to SilcDList and changed code
1853 * NAMES command can now be used from user interface. It will show
1854 the user list on the channel, neatly.
1856 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1857 Code now saves realname of the user if it becomes available.
1859 * Renamed configure.in to configure.in.pre and made ./prepare
1860 script to automatically add correct version string to
1861 configure.in which it creates from configure.in.pre.
1863 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1865 * NAMES command reply now shows users mode with the nickname when
1868 * Moved silc_client_ch[u]mode[_char] functions from
1869 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1870 place sucks, they are utility functions and should be in some
1873 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1875 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1878 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1882 * Added TRQ (efficient deque and list library) into lib/trq. This is
1883 a very good list library that is currently used in the SILC. Defined
1884 SilcList API over the library because I didn't like the API very
1885 much. See lib/trq/silclist.h for the API and examples of how to
1886 use the API. Fixed various places in the code to use the new
1887 SilcList API. The SilcList is meant for lists that has a structure
1888 already defined as a list. It is not suitable to add just some
1889 context to the list (in TRQ, the context is the list actually).
1891 So, I defined SilcDList that can be used for the purpose where
1892 predefined list structure does not exit. This can be used as
1893 such list. Now some context just can be added to the SilcDList.
1894 Currently this list is not used in the SILC just yet, though there
1895 are a lot places where this can replace dynamically allocated
1896 tables and I will fix these places, later, to use SilcDList.
1897 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1898 and use TRQ internally).
1900 Also fixed some annoying warning messages that the original TRQ
1901 code generated. Also minor changes to TRQ's Makefile.in.
1903 * Added support for querying by Client ID to both WHOIS and
1904 IDENTIFY commands into server, as required by the protocol.
1906 * Removed method function pointers from SilcBuffer structure. They
1907 weren't used to anything and just increased the context size for
1908 no good reason. This change also made silc_buffer_alloc and
1909 silc_buffer_free functions inline functions.
1911 * Disabled command flooding detection support until it's fixed so
1912 that it accepts commands in but does not execute them more than once
1915 * Added silc_net_localhost(), to return local hostname, into
1916 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1917 that must be initialized before calling silc_client_init.
1919 * Added new function: silc_server_send_notify_on_channels to send
1920 notify messages to all channels client has joined. It is assured
1921 that the message is sent only once per client.
1923 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1924 lib/silcutil/silcutil.[ch] as silc_format function. The new
1925 function is generic and is used by server as well, not only by
1926 the logging routines.
1928 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1929 the provided version string was not acceptable. Added new function:
1930 silc_ske_check_version into lib/silcske/silcske.h. The function
1931 must be implemented by the application (client or server) and it
1932 does not reside in the SKE library. The function checks the version
1933 string remote end sent.
1935 * Added back pointers (to opaque context and to SilcSocketConnection)
1936 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1938 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1939 duplicate packet context structure.
1941 * Changed `notify' client operation to send same arguments as client
1942 receives from server except for ID's. ID's are mapped to correct
1943 ID entry and that is returned. Also, if channel entry is not sent
1944 by server but the notify is for channel the channel entry is sent
1945 to application (otherwise application doesn't know that it is for
1946 channel (library gets it from packet's Destination ID)).
1948 * Added silc_client_remove_from_channels into client library to
1949 remove a client from all channels it has joined to. Used when
1950 received SIGNOFF notify from server. Added also new function
1951 silc_client_replace_from_channels to replace old ID entry with
1952 new ID entry on all channels. Used when received NICK_CHANGE
1955 * Fixed ID Cache list handling in silc_idlist_get_client in
1956 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1957 to get (or query) client by ID.
1959 * Updated TODO list.
1961 * Added connection authentication status message defined by the
1962 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1963 support for these into the code in client and server side.
1965 * Added generic function silc_client_send_command to send any command
1966 with variable argument list. Application should use this function
1967 to send commands if the command functions provided by the library
1968 does not suite for the application's user interface needs.
1970 * Added new `failure' client operation. Application is notified about
1971 received failure packet if client is executing a protocol. In this
1972 case the protocol's execution has failed.
1974 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1975 is required by the protocol.
1977 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1978 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1981 * Added status flag to SilcSKE object to indicate realtime status
1982 of the SKE protocol.
1984 * Application receives now exactly same command reply arguments as
1985 the library receives from server. However, if ID is received the
1986 corresponding ID entry is returned to the application (eg. Client
1987 ID is mapped to correct SilcClientEntry entry and that is returned).
1988 Changed command_reply client operation due to this change.
1990 * Changed all ID's in commands and in command replys as ID Payloads.
1991 Change affected both client and server side codes.
1993 All ID's sent in SILC network (with execption of ID's in SILC
1994 Packet header) are sent in ID Payload to support variable length
1997 * Server now notifies nick changes and notifies all clients on
1998 the channels about the new nickname (about the new Client ID,
2001 * Implemented CMODE command to change channel modes. Supports all
2002 channel modes defined by the protocol specs except ban and invite
2003 lists. (Also, private channel key mode is supported but support for
2004 setting private channel key in client is missing, thus, this mode
2005 has no effect on client side (except that server requires that the
2006 client uses private channel key and normal channel traffic does not
2009 Also, invite mode works per se, but INVITE command does not work
2010 yet correctly, so you can set channel as invite only channel but
2011 inviting clients to the channel does not work (it is yet to be
2012 thought what's the best way to do it).
2014 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2015 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2016 Implemented CUMODE command to change user's mode on the channel.
2017 Supports all modes defined by the protocol specs.
2019 * Added NAMES command reply to return users modes on the channel.
2021 * Removed unnecessary and slow ciphers from lib/silccrypt.
2023 * Set SO_KEEPALIVE option to connection sockets by default.
2025 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2027 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2028 redefined the Notify Payload into protocol specs.
2030 * Added silc_id_payload_parse_id to get ID directly from raw
2033 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2035 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2036 accept searching by Client ID as well.
2038 * Added support for LEAVE and SIGNOFF notify types in client library.
2040 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2041 to parse ID Payload from raw data.
2043 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2045 * Added flags parameter into silc_ske_assemble_security_properties
2046 function in lib/silcske/silcske.[ch].
2048 * Changed notify client operation to fit better for notify messages
2049 sent by server. The notify payload received from server is now
2050 passed to the application (after parsing it to SilcNotifyPayload).
2051 It is application's responsibility to retrieve the arguments
2052 from the payload and show the message the way it wants. The message
2053 sent by server is implementation specific.
2055 * Changed public keys to comply with the protocol specification.
2056 Old public keys are not supported anymore and are not compatible.
2058 * Removed nickname from Channel Payload as the latest draft removed
2059 it. The client must resolve the nickname from the NAMES command
2060 reply received when it joined the channel.
2062 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2064 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2066 * Fixed some errors in protocol specification drafts.
2068 * Created lib/silccore/silcnotify.c to implement Notify Payload
2069 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2070 generic payloads described by protocol specifications. The file
2071 includes implementations for ID Payload and Argument Payload.
2073 * Changed Command Payload implementation to use the new Argument
2074 Payload. Changed command_xxxx_payload to command_payload_xxxx
2075 to comply with SILC coding conventions.
2077 * Added suppport for Argument Payload handling in Notify Payload
2078 implementation as protocol requires it. Added the new support
2079 into server and client lib as well.
2081 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2083 * Added support for multiple nicknames on same channel. [n] is
2084 added locally to the nickname if there are more than one same
2085 nicknames on the channel.
2087 * Server now sends all nicknames that matched WHOIS request.
2088 Client also shows the list received from server.
2090 * Added TOPIC command to client side. User can now set and show
2091 current topic on channel.
2093 * Added MOTD command to client and server. Also, server sends the
2094 motd when client connects to the server.
2096 * Changed version strings to comply ISO 8601.
2098 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2100 * Fixed protocol error handling in client library. It should now
2101 cope even if the SKE fails for some reason.
2103 * Made new protocol specification drafts for submitting to IETF.
2105 * Implemented TOPIC command to server in silcd/command.c.
2107 * Added two new notify types into lib/silccore/silcnotify.h:
2108 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2109 notify nickname change and topic setting/change on a channel.
2111 * API change of command_reply operation in client library. The
2112 application gets now the status type received from server as well.
2114 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2116 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2118 * Cras fixed and optimized the packet handling even further and
2119 it should work now. Minor change to the prototype of function
2120 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2122 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2124 * Added new function into lib/silcutil/silcschedule.[ch]:
2125 silc_schedule_with_fd to select() a specified fd. The function
2126 returns after timeout expires or data arrives or goes. The
2127 function is used by packet routines to wait that all data is
2128 received from network.
2130 * Fixed data reading from network in lib/silccore/silcpacket.c.
2131 The code now assures that all data is read from the fd and then
2132 continues packet processing. This was a bug fix since the code
2133 used to drop some data in some circumstances.
2135 * Added new function into lib/silcclient/client.[ch]:
2136 silc_client_start_key_exchange to start key exchange after
2137 connection has been established to server. The code internally
2138 now uses this funtion but its main purpose was to provide it
2139 for applications that perform their own connecting. After
2140 application has created a connection it merely calls this
2141 function to start the key exchange between client and server.
2142 The library takes care of everything else after that.
2144 Updated also lib/silcclient/README to explain the usage of
2147 * Do not send to application information that connection has
2148 been established. Application gets notified it by connect
2151 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2153 * Applied cras's patch to add silc_schedule_one function. The
2154 function runs scheduler once and returns.
2156 * Fixed the scheduler after cras messed it up. The timeout
2157 handling works now as it's supposed to work.
2159 * Added into lib/silccore/ silcnotify.h to include notify
2160 message types support. Changed silc_server_send_notify*
2161 functions, in server.[ch], to support those new notify types.
2162 Added the support for the notify types into client library,
2163 as well. Added new notify client operation into ops.h in
2166 * Changed silc_server_packet_send_to_channel to send normal
2167 packets instead of just channel message packets. The function
2168 is now used to send the notify packets to channels. It is not
2169 used to send channel message packets anymore, as server never
2172 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2173 va_arg()s as it seems to require it nowadays. I guess, if SILC
2174 is compiled with older va_arg() the new code should work anyway.
2176 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2178 * Splitted core library. Core library (lib/silccore) includes
2179 now only SILC protocol specific core (and common) components.
2180 Created new utility library (lib/silcutil) that includes more
2181 generic purpose stuff. The stuff for util library was taken
2182 from the old core library. This was minor and easy split.
2184 * Created SILC Client Library (lib/silcclient) that includes
2185 implementation of the SILC client without user interface. This
2186 was major move from silc/ directory. The code has been changed
2187 so that it is transparent towards the user interface. The
2188 silc/ directory includes now the same user interface as before
2189 and it uses the new client library. Read lib/silcclient/README.
2190 Basicly, the client library performs everything else related
2191 to SILC except user interface handling. Also, configuration
2192 files are considered to be part of user interface and library
2193 does not handle them.
2195 This change also changed a lot of structures, function naming etc.
2196 Most important change was that SilcClientWindow object was
2197 renamed to SilcClientConnection in the client library. Created
2198 also new file lib/silcclient/ops.h. Also added new files
2199 silc/local_command.[ch] and silc/client_ops.[ch].
2201 All these changes were made to make it easier for user interface
2202 designers to create what ever user interface for the SILC client
2205 It is also expected that the server will be moved to lib
2206 directory as well and SILC Server Library will be created;
2207 sometimes in the future.
2209 * Removed Local commands from lib/silccore/silccommand.h as
2210 they are application specific and new client library does not
2211 handle any of those anymore.
2213 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2214 old client implementation in silc/.
2216 * Added support for callback functions in SILC_LOG_* macros.
2217 Application can now set its own callbacks that will be called
2218 instead of using the default functions that will always print
2219 the debug messages to stderr (or stdout). Also, debugging can
2220 now be disabled by setting silc_debug to FALSE and re-enabled by
2221 setting it to TRUE. Note, that logging will still work even
2222 if debugging is disabled.
2224 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2225 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2226 silc_log_reset_debug_callbacks.
2228 * To enable debugging in silc client one must give now -d
2229 option on command line.
2231 * Changed silc_schedule_init to automatically allocate task queues
2232 if they are not allocated before calling it.
2234 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2236 * Added GMP 3.1 into math library.
2238 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2240 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2241 a channel in SILC network. The packet is used by servers and
2242 routers to notify other routers that user has left a channel.
2243 This little feature was missing until now. Added the feature
2244 to protocol specification as well.
2246 Added functions: silc_server_send_remove_channel_user and
2247 silc_server_remove_channel_user into server.[ch].
2249 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2250 lib/silccore/silcpacket.h. However, they are not implemented
2253 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2255 * Fixed joining to a channel and sending channel messages
2256 between server and router. The channel message sending should
2257 now work inside a cell.
2259 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2261 * Fixed the private message sending between server and router.
2262 The private message sending should now work inside a cell.
2264 * Added silc_server_replace_id into server.[ch] to replace
2265 existing ID in the SILC network.
2267 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2268 and silc_idlist_replace_server_id into idlist.[ch] in server.
2270 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2272 * Fixed the server to server connections. Server can again now
2273 connect to router. Router to router connections probably does
2276 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2278 * Added dynamic protocol registering support. Now protocols can
2279 registered and unregistered on the fly. Patch by cras.
2281 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2283 * Added lib/contrib directory to hold routines that some platforms
2284 don't have but are needed by SILC.
2286 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2287 into lin/contrib to provide getopt() and getopt_long() for
2288 those who don't have it.
2290 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2292 * Added AWAY command to client. When away message is set and
2293 client receives a private message packet the client automatically
2294 replies to the sender with the away message.
2296 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2297 bug seemed to be the cause of recent problems when compiling
2300 * Added version detection support to SKE protocol specification
2301 and added the new changes to the SKE implementation as well.
2302 There were other minor changes in the SKE protocol as well.
2304 Many changes in lib/silcske/silcske.[ch] and in
2305 lib/silcske/payload.[ch].
2307 * Added ^U functionality, clear input line. Patch from cras.
2309 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2311 * Mainly small bugfixes on core library. Fixed some debugging
2312 logging and buffer overflow in silclog.c.
2314 * Updated config.sub and config.guess on the distribution tree.
2316 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2318 * Added command lagging support in server. Client may execute
2319 commands now only once in two seconds.
2321 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2323 * Optimized packet reception. MAC computation and checking is now
2324 also more optimized. A lot previously duplicated code is now
2325 used as generic by both client and server.
2327 * Fixed key pair generation in clientutil.c
2329 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2331 * Added into lib/silccore/silcbufutil.[ch] new function;
2332 silc_buffer_realloc.
2334 * Moved generic packet sending/encryption functions to
2335 lib/silccore/silcpacket.[ch] from client and server. Some
2336 rewriting of the functions.
2338 * Moved all generic packet reception/decryption functions to
2339 lib/silccore/silcpacket.[ch] from client and server. The
2340 packet processing is now much cleaner in both client and server.
2341 These were major changes in both client and server.
2343 * Created many common functions in server to do packet sending.
2344 Previously code were duplicated a lot, this has been removed
2347 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2349 * Rewrote major parts of the ID cache system. Don't know
2350 whether it is better now or not but at least the API is more
2353 * Major rewrite on ID cache stuff on client because of the ID
2354 cache API changes. Added idlist.c to client.
2356 * Also major rewrite on ID cache stuff on server as well.
2357 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2358 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2359 in hand, instead they are all put into the ID cache system now.
2360 All server_idlist_* routines uses ID cache now instead of
2361 traversing its own lists (those lists does not exist anymore).
2362 SilcIDList though still exists. Also, SilcXXXEntry's are
2365 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2367 * Finally made the SKE implementation compliant to the protocol
2368 specification. All mp integers are now binary encoded as
2369 opposed being HEX encoded.
2371 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2374 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2375 functions: silc_[encode/decode]_pem. Also added function
2376 silc_encode_pem_file to PEM encode with newlines ('\n') for
2379 * SILC public keys are now encoded either PEM or binary. Same
2380 option is for private keys as well. By default private keys
2381 are binary encoded and public keys PEM encoded. Silly HEX
2382 encoding were removed.
2384 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2385 function to create fingerprints.
2387 * Fixed a bug in SHA1; does not change the original data anymore.
2389 * Partly implemented INFO command on client and server side.
2390 Fixed CLEAR command. Changes to SERVER command; show current
2391 server(s) when giving command without arguments. Added
2392 VERSION command to client.
2394 * Added check to server that unregistered connections cannot
2395 execute commands (unless it is specificly allowed).
2397 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2399 * Fixed screen refresh.
2401 * Fixed channel joining bug from client. On some circumstances
2402 client tried to join to a channel it had already joined.
2404 * Added public key verification process into client's protocol.c.
2405 The client now verifies the public key from user and saves
2406 it into ~./silc/serverkeys/ directory.
2408 Added into: clientutil.[ch]: silc_client_verify_server_key.
2410 * Changed SKE protocol's silc_ske_initiator_finish function
2411 to accept callback function that verifies the received public
2412 key. Removed old silc_ske_verify_public_key function.
2414 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2416 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2417 silc_pkcs_private_key[_data]_set.
2419 * Made the password and public authentication more cleaner in
2420 server's protocol.c.
2422 * Removed historic and obsolete protocol `channel_auth' from
2423 both client and server.
2425 * Removed wrong way of sending command status messages from
2426 server to client in server's command.c. The old way violated
2427 protocol specification.
2429 Changes to silccore/silccommand.[ch]: removed
2430 silc_command_encode_status_payload -> not needed anymore,
2431 changed silc_command_encode_payload_va to accept extra
2432 argument on variable argument list. The argument type must
2433 now be provided to the function. Also, added new function:
2434 silc_command_encode_reply_payload_va which is same as
2435 normal command_encode_payload_va except command status type
2436 is provided as extra argument.
2438 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2440 * Added ~./silc directory handling. The directory includes the
2441 public and private keys for the client.
2443 Added silc_client_check_silc_dir, silc_client_create_identifier
2444 and silc_client_load_keys.
2446 * Implemented SILC protocol compliant public key. Added public
2447 and private key saving to and loading from files.
2449 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2450 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2451 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2452 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2453 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2455 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2456 silc_pkcs_load_[public/private]_key.
2458 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2460 * Added silc_server_get_route (route.[ch]) to get connection
2461 data for the fastest route for given ID.
2463 * Implemented INVITE command on client and server. The command
2464 were re-defined in the SILC Protocol Specification and the
2465 implementation now complies with the specification.
2467 * Implemented PING command on client and server.
2469 * Implemented NAMES command on client and server. The server side
2470 supports currently only normal server not router server yet.
2471 Some changes to NAMES definition in SILC protocol specification.
2473 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2475 * Implemented LEAVE command on client and server.
2477 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2478 again. This change was made to the protocol as well. Server
2479 should not violate the protocol specification anymore.
2481 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2483 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2484 was tested. SOCKS4 was not but should work anyway.
