1 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed the mode printing on the user interface on joining.
4 Affected file silc/client_ops.c.
6 * Implemented the UMODE command and user modes in general to the
7 client library and to the user interface.
9 * Implemented the UMODE command to the server.
11 * The server now sends UNKNOWN_COMMAND error status if client sends
12 unknown command. Affected file silcd/command.c.
14 * All server commands now handle the command identifier the right
15 way when sending the command reply to the client. The client can
16 use to identify the command replies with the identifier.
18 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
20 * Added silc_server_get_client_route to resolve the route to
21 the client indicated by the client ID. Affected file is
24 * Added silc_server_relay_packet as general function to relay
25 packet to arbitrary destination. This deprecates functions
26 like _send_private_message_key, _relay_notify etc. Affected
27 file is silcd/packet_send.[ch].
29 Removed silc_server_send_key_agreement,
30 silc_server_send_private_message_key and
31 silc_server_packet_relay_notify functions from the file
32 silcd/packet_send.[ch].
36 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
37 server. Affected file silcd/packet_receive.[ch].
39 * Implemented the KILL command to the client. Implemented the
40 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
41 Affected files lib/silcclient/command[_reply].c and
42 lib/silcclient/client_notify.c. Implemented the KILL notify
43 printing in the user inteface.
45 * Fixed a lot silc_parse_nick memory leaks from the client
46 library in the file lib/silcclient/command.c.
48 * Changed the silc_server_send_notify_on_channels's `sender'
49 argument from SilcSocketConnection to SilcClientEntry to
50 check the sender as entry and not as connection object and not
51 to send to the client provided as argument. The affected file
52 is silcd/packet_send.[ch].
54 * The notify packets that are destined directly to the client used
55 to not to be processed by the server. Now changed that and the
56 server processes all notify packets. After relaying the packet
57 to the client the notify packet is processed in the server.
59 * The silc_server_free_client_data now checks whether there is
60 pending outgoing traffic for the client and purges the data to
61 the network before removing the client entry.
63 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
65 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
66 an client is killed from the SILC Network. Updated the protocol
69 Added new function silc_server_send_notify_killed to the
70 silcd/packet_send.[ch].
72 * Added function silc_server_packet_relay_notify to relay notify
73 packets that are destined directly to a client. In this case
74 the server does not process the notify packets but merely relays
75 it to the client. Affected file silcd/packet_send.[ch].
77 Added also silc_server_packet_process_relay_notify to check
78 whereto relay the notify. Affected file is
79 silcd/packet_receive.[ch].
81 * Implemented the KILL command to the server.
85 * Added the backup schema desgined last fall to the protocol
86 specs for everyone to see. The specification is in the
87 *-spec-xx.txt draft and the packet type definitions for the
88 backup routers is in *-pp-xx.txt draft. Thusly, added also
89 new packet type SILC_PACKET_CELL_ROUTERS.
91 * A big security problem in the implementation discovered. The
92 signoff of an client did not cause new channel key generation
93 which it of course should've done. The channel keys must be
94 always re-generated when client leaves (or signoffs) the channel.
95 The silc_server_remove_from_channels funtion now handles
96 the channel key re-generation.
98 * Added `sender' argument to the silc_server_send_notify_on_channels
99 to not to send the client provided as argument. Affected file
100 silcd/packet_send.[ch].
102 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
104 * Implemented OPER and SILCOPER commands into the server and
107 * Added silc_auth_verify and silc_auth_verify_data to verify
108 the authentication directly from the authentication payload.
109 It supports verifying both passphrase and public key based
110 authentication. Affected file lib/silccore/silcauth.[ch].
112 * Added `hash' field to the SilcIDListData structure. It is the
113 hash negotiated in the SKE protocol. Affected file is
116 * Slight redesigning of the SilcAuthPayload handling routines.
117 Do not send SilcPKCS but SilcPublicKey as argument.
119 * Implemented the public key authentication support to the
120 serverconfig. The public key is loaded fromthe provided path
121 and saved as authentication data to void * pointer. Thus,
122 changed the unsigned char *auth_data to void *auth_data;
124 * Fixed SHUTDOWN command to send the reply before the server
125 is shutdown. :) Affected file silcd/command.c.
127 * Fixed fatal bug in CONNECT command. The hostname was invalid
128 memory and server crashed. Affected file silcd/command.c.
130 * Fixed fatal bug in CLOSE command. The server_entry became
131 invalid but was referenced later in the command. Affected file
134 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
136 * Fixed fatal bug in failure packet handling. Server ignored
137 the failure and thus crashed when it came.
141 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
143 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
144 that the command may be executed only once in (about) 2 seconds.
145 The old SILC_CF_LAG flag is same but allows command bursts up
146 to five before limiting.
148 Added the support for CF_LAG and CF_LAG_STRICT flags to the
149 server code. Various commands now includes the CF_LAG_STRICT
150 flag to disallow any kind of miss-use of the command.
152 * Fixed the silc_buffer_unformat to not to allocate any data
153 if the length of the data is zero. It used to allocate the
154 length + 1. Affected file lib/silcutil/silcbuffmt.c.
156 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
158 * Changed the format of AdminConnection configuration section
159 in the server. Added username of the admin to the format.
160 Affected files silcd/serverconfig.[ch].
162 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
163 to return admin configuration data by host, username and/or
166 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
168 * Implemented WHOWAS command to the server. Added the functions:
170 silc_server_command_whowas_parse,
171 silc_server_command_whowas_send_reply,
172 silc_server_command_whowas_from_client and
173 silc_server_command_whowas_from_server
175 * Added <Client ID> argument to the WHOWAS command reply. Updated
176 the protocol specs accordingly.
178 * Implemented WHOWAS command and command_reply to the client
181 Implemented the WHOWAS printing on the user interface.
183 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
185 * Added new argument to the WHOWAS command reply, the real name.
186 It is an optional argument. Updated the protocol specs.
188 * Added SilcIDCacheDestructor callback that is registered when
189 the SilcIDCache is allocated. The callback is called when
190 an cache entry in the ID Cache expires, or is purged from the
191 cache. Added into lib/silccore/idcache.[ch].
193 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
194 to destruct the client entries when the cache entry expires.
195 Other ID Cache's in server and in the client library ignores
198 * If the ID Cache entry's `expire' field is zero then the entry
199 never expires. Added boolean `expire' argument to the
200 silc_idcache_add function in the lib/silccore/idcache.[ch].
201 If it is TRUE the default expiry value is used.
203 * Added silc_server_free_client_data_timeout that is registered
204 when client disconnects. By default for 5 minutes we preserve
205 the client entry for history - for WHOWAS command.
207 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
209 * Added support to the server to enforce that commands are not
210 executed more than once in 2 seconds. If server receives
211 commands from client more frequently, timeout is registered
212 to process the commands. Affected file silcd/command.c.
213 Added new function silc_server_command_process_timeout.
215 * Changed NICK_NOTIFY handling in client library to check that
216 if the client's nickname was changed, so there is no need to
217 resolve anything from the server.
219 * Removed error printing from the WHOIS and IDENTIFY commands.
220 If error occurs then it is ignored silently in the client library.
221 The application, however, may map the received error to
222 human readable error string. The application currently maps
223 the NO_SUCH_NICKNAME error to string.
225 * Made the command status message public to the application. Moved
226 them from lib/silcclient/command_reply.c to
227 lib/silcclient/command_reply.h. The application can map the
228 received command status to the string with the
229 silc_client_command_status_message function.
231 * Added check to the server to check that client's ID is same
232 as the Source ID in the packet the client sent. They must
235 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
237 * Added dist-bzip hook to the Makefile.am to make bzip2
238 compressed distributions.
240 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
242 * Server now enforces the maximum length for the nickname and
243 the channel as protocol specification dictates. 128 bytes for
244 nickname and 256 bytes for channel name.
246 * Moved the WHOIS printing to the application. The client libary
247 does not print out the WHOIS information anymore, the application
248 must do it. Renamed silc_client_command_reply_whois_print to
249 the silc_client_command_reply_whois_save.
251 The client's idle time is also sent to the application now, and
252 the idle is shown on screen.
254 * Added silc_client_command_reply_identify_save to save the
255 received IDENTIFY entries.
257 * Do not check for channel private keys in message sending and
258 reception if the channel does not have the PRIVKEY mode set.
259 Affected file lib/silclient/client_channel.c.
261 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
263 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
264 just surfaced after chaning the JOIN procedure.
266 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
268 * Added silc_client_get_clients_by_list to get client entries
269 from Client ID list, that is returned for example by JOIN
270 and USERS command replies. The application should use this
271 function for example when JOIN command reply is received to
272 resolve the clients already on the channel (library does not
273 do that anymore as USERS command reply is not used in the JOIN
274 procedure anymore). Affected files lib/silcclient/silcapi.h and
275 lib/silcclient/idlist.c.
277 * JOIN command reply and USERS command reply returns now SilcBuffer
278 pointers instead of unsigned char pointers when returning
279 the client list and mode list.
281 * Added <Client ID> argument to the JOIN command reply, mainly
282 for the server to identify for which client the command was
283 originally sent. Updated protocol specs accordingly.
285 * Added SilcDlist private_key pointer to the SilcChannelEntry
286 in the client to support the channel private keys. Affected
287 file is lib/silcclient/idlist.h.
289 * Added SilcChannelPrivateKey argument to the function
290 silc_client_send_channel_message so that application can choose
291 to use specific private ke if it wants to. If it is not provided,
292 the normal channel key is used, unless private keys are set.
293 In this case the first (key that was added first) is used
294 as the encryption key.
296 * Implemented the support for channel private key handling.
297 Implemented the following functions:
299 silc_client_add_channel_private_key,
300 silc_client_del_channel_private_keys,
301 silc_client_del_channel_private_key,
302 silc_client_list_channel_private_keys and
303 silc_client_free_channel_private_keys
305 Affected file lib/silcclient/client_channel.c.
307 * Added the support for the private keys in the channel message
308 sending and encryption and in the message reception and
309 decryption. Affected funtions are
310 silc_client_send_channel_message and silc_client_channel_message.
312 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
314 * Added SKE's key verify callback to the client library's
315 KE protocol context. Affected files lib/silcclient/protocol.[ch].
317 * Removed the statement that server (or router) must send USERS
318 command reply when joining to the channel so that the client
319 knows who are on the channel. Instead, the client list and
320 client's mode list is now sent in the JOIN command reply to the
321 client who joined channel. This is better solution.
323 * Added function silc_server_get_users_on_channel and function
324 silc_server_save_users_on_channel to the silcd/server.[ch].
326 * Removed function silc_server_command_send_users from the
329 * Do not show topic on the client library anymore. The topic is
330 sent in the command reply notify to the application and the
331 application must show the topic now.
333 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
335 * Added client searching by nickname hash into the IDENTIFY and
336 WHOIS commands in the server as they were clearly missing from
337 them. Affected file is silcd/command.c.
339 * Fixed a bug in private message receiving in the client library.
340 The remote ID was freed and it wasn't supposed, now it is
343 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
345 * Minor fix to the channel payload; allocate the data area, as it
346 needs to be of specific length.
348 * If the key agreement port is zero then the operating
349 system will define the bound port. Affected files are
350 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
352 * Added new function silc_channel_payload_decrypt into the file
353 lib/silccore/silcchannel.[ch].
355 * Moved the channel message etc, check from silc_packet_decrypt
356 to applications. The library calls now a generic
357 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
358 when the packet is either normal or special. This was done to
359 allow more wide range of checking that was not allowed when
360 the code was in library. Now applications can do virtually any
361 checks to the packet and return to the library the decision how
362 the packet should be processed. Affected files are
363 lib/silccore/silcpacket.[ch].
365 Added silc_server_packet_decrypt_check to the server and
366 silc_client_packet_decrypt_check to the client library.
368 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
369 to send with specified source and destination information.
371 * Channel message delivery between routers was broken after the
372 channel key distribution was fixed earlier. The channel key
373 was used be to distributed to other routers as well which is not
374 allowed by the protocol. Now this is fixed and channel keys
375 really are cell specific and the channel message delivery between
376 routers comply with the protocol specification.
378 * Fixed various commands in server to check also the global list
379 for the channel entry and not just the local list. The affected
380 file silcd/command.c.
382 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
384 * Added assert()s to buffer formatting and unformatting routines
385 to assert (if --enable-debug) when error occurs. Affected
386 file: lib/silcutil/silcbuffmt.c.
388 * Changed to auto-reconnect to check whether the remote host is
389 router and register the re-connect timeout if it is. It used
390 to check that whether we are normal server, but router must do
391 auto-reconnect with another router as well. Affected file
394 * Removed the [<key len>] option from CMODE command as the cipher
395 name decides the key length, nowadays. See the defined ciphers
396 from the protocol specification.
398 * Added [<hmac>] option to the CMODE command to define the HMAC
399 for the channel. Added SILC_CMODE_HMAC channel mode.
401 * Added [<hmac>] option for the JOIN command so that user can
402 select which HMAC is used to compute the MACs of the channel
405 * Added Hmac field to the Channel Message Payload. The integrity
406 of plaintext channel messages are now protected by computing
407 MAC of the message and attaching the MAC to the payload. The
408 MAC is encrypted. Now, it is clear that this causes some
409 overhead to the size of the packet but rationale for this is that
410 now the receiver can verify whether the channel message decrypted
411 correctly and also when private keys are set for the channel the
412 receiver can decrypt the packet with several keys and check from
413 the MAC which key decrypted the message correctly.
415 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
416 lib/silccrypt/silccipher.[ch].
418 * Added silc_hash_len to return the digest length into the
419 lib/silcrypt/silchash.[ch].
421 * Rewrote parts of Silc Channel Payload interface in the
422 lib/silccore/silcchannel.[ch]. The encode function now also
423 encrypts the packet and parse function decrypts it.
425 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
427 * Fixed a minor formatting bug in the SKE's key material processing.
428 It actually might have processed the keys wrong way resulting
431 * Redefined the mandatory HMAC algorithms and added new algorithms.
432 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
433 and hmac-md5 truncated to 96 bits. The mandatory is now
434 hmac-sha1-96. Rest are optional (including the one that used
435 to be mandatory). Rationale for this is that the truncated HMAC
436 length is sufficient from security point of view and can actually
437 make the attack against the HMAC harder. Also, the truncated
438 HMAC causes less overhead to the packets. See the RFC2104 for
441 * Added new [hmac] configuration section. The SKE used to use
442 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
443 is of course wrong. The official names that must be proposed in
444 the SKE are the ones defined in the protocol specification
445 (hmac-sha1-96 for example). The user can configure any hmac
446 using any hash function configured in the [hash] section. At
447 least, the mandatory must be configured.
449 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
451 * Added HMAC list to the SKE proposal list. It has now both
452 hash algorithm list and HMAC list. This makes the protocol
453 incompatible with previous versions. The SKE now seems to work
454 the way it is supposed to work, for the first time actually.
456 * Defined plain Hash algorithms to the protocol specification.
459 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
461 * Implemented support for key agreement packets into the server.
462 Added functions silc_server_key_agreement and
463 silc_server_send_key_agreement. Other than these functions,
464 server has nothing to do with this packet.
466 * Added support for private message key packets into the server.
467 Added functions silc_server_private_message_key and
468 silc_server_send_private_message_key.
472 * Changed the silc_[client|server]_protocol_ke_set_keys to be
473 called in the protocol's final callback instead in the END
474 protocol state. This makes a little more sense and in the same
475 time in client we can use the same protocol routines for normal
476 key exchange and to key agreement packet handling as well.
478 * Added to both client's and server's KE protocol context the
479 SilcSKEKeyMaterial pointer to save the key material. We will
480 bring the key material to the protocol's final callback by doing
481 this. The final callback must free the key material.
483 * Added SKE's packet_send callback into client's KE protocol
484 context so that the caller can choose what packet sending function
485 is used. This way we can use different packet sending when
486 doing normal SKE when doing key agreement packet handling (in
487 the key agreement packet handling we do not want to encrypt
490 * Implemented the responder side of the key agreement routines
491 in the client. The client can now bind to specified port and
492 accept incoming key negotiation. The key material is passed
493 to the application after the protocol is over.
495 * Implemented the processing of incoming Key Agreement packet
496 in the client. Added function silc_client_key_agreement to
499 * Implemented the intiator side of the key agreement routines
500 in the client. The client can now initiate key agreement with
501 another remote client. The key material is passed to the
502 application after the protocol is over.
504 * Created client_keyagr.c to include all the key agreement
507 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
508 SILC_TASK_CALLBACK except that it is not static.
510 * Created client_notify.c and moved the Notify packet handling
511 from the client.[ch] into that file.
513 * Created client_prvmsg.c and moved all private message and
514 private message key routines from the client.[ch] into that file.
516 * Create client_channel.c and moved all channel message and
517 channel private key routines from the client.[ch] into that file.
519 * Changed silc_client_get_client_by_id_resolve to resolve with
520 WHOIS command instead of IDENTIFY command, in the file
521 lib/silclient/idlist.c.
523 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
525 * Implemented the SKE's responder side to the Client library.
527 * When FAILURE is received to the protocol do not trust it
528 blindly. Register a timeout to wait whether the remote closes
529 the connection as it should do it, only after that process the
530 actual failure. This was changed to both client and server.
532 * Added client_internal.h to include some of the structures
533 there instead of client.h in lib/silcclient/.
535 * Added function silc_task_unregister_by_callback to unregister
536 timeouts by the callback function.
538 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
540 * Some "Incomplete WHOIS info" errors has been appearing on the
541 log files. Took away the entry->userinfo check from WHOIS
542 reply sending. The entry->userinfo is now " " if client did not
543 provide one. I thought this was fixed earlier but something
544 is wrong still. Let's see if the error still appears.
546 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
548 * Fixed a minor bug in the login when the channel key is
549 re-generated in the server. It used to generate the key in
550 wrong order and thus caused problems in the channel traffic.
552 * Fixed a minor bug in channel key distsribution after
553 KICK command. The key was not sent to the router even though
556 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
558 * Added silc_ske_process_key_material_data as generic routine
559 to process any key material as the SILC protocol dictates. The
560 function is used by the actual SKE library but can be used by
561 applications as well. This relates to the private message keys
562 and the channel private keys since they must be processed the
563 same way the normal SILC session keys. The protocol dictates
564 this. Affected files: lib/silcske/silcske.[ch].
566 Added also silc_ske_free_key_material to free the
567 SilcSKEKeyMaterial structure.
569 * Defined silc_cipher_set_key function to set the key for
570 cipher without using the object's method function. The affected
571 files: lib/silccrypt/silccipher.[ch].
573 * Implemented silc silc_client_add_private_message_key,
574 silc_client_add_private_message_key_ske,
575 silc_client_del_private_message_key,
576 silc_client_list_private_message_keys and
577 silc_client_free_private_message_keys functions in the
580 Added functions silc_client_send_private_message_key to send
581 the Private Message Key payload and silc_client_private_message_key
582 to handle incoming Private Message Key payload.
584 * Added Cipher field to the Private Message Key payload to set
585 the cipher to be used. If ignored, the default cipher defined
586 in the SILC protocol (aes-256-cbc) is used.
588 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
590 * Removed lib/silcclient/ops.h file.
592 Redefined parts of the SILC Client Library API. Created new
593 file silcapi.h that deprecates the ops.h file and defines the
594 published Client Library API. Defined also private message key
595 API and channel private key API into the file.
597 This is the file that the application must include from the
598 SILC Client Library. Other files need not be included by
599 the application anymore.
601 * Added new key_agreement client operation callback and also
602 defined the Key Agreement library API for the application.
604 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
606 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
607 is used by clients to request key negotiation between another
608 client in the SILC network. If the negotiation is started it
609 is performed using the SKE protocol. The result of the
610 negotiation, the secret key material, can be used for example
611 as private message key.
613 Implemented the Key Agreement payload into the files
614 lib/silccore/silauth.[ch].
616 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
618 * Redefined ciphers for the SILC protocol. Added some new ciphers
619 and defined the key lengths for the algorithms. Changed the
620 code accordingly. The default key length is now 256 bits.
622 * Fixed SKE key distribution function silc_ske_process_key_material
623 when the key length is more than 128 bits. The default key
624 length in SILC is now 256 bits.
626 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
627 to indicate unsupported algorithm.
629 * Renamed rijndael.c to aes.c and all functions as well.
631 * Fixed a long standing channel key setting bug in client library.
632 Weird that it has never surfaced before.
634 * Fixed bug in channel deletion. If the entire channel is removed
635 then it must also delete the references of the channel entry
636 from the client's channel list as the client's channel entry and
637 the channel's client entry share same memory.
639 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
641 * Implemented CONNECT and SHUTDOWN commands in the client.
643 * Implemented CLOSE command to the client.
645 * Added the function silc_idlist_find_server_by_name into the
646 files silcd/idlist.[ch].
648 Added the function silc_idlist_find_server_by_conn into the
649 files silcd/idlist.[ch].
651 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
653 * DIE command was renamed to SHUTDOWN. Updated the both code
656 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
657 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
659 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
662 * Added function silc_server_create_connection function to create
663 connection to remote router. My server implementation actually
664 does not allow router to connect to normal server (it expects
665 that normal server always initiates the connection to the router)
666 so the CONNECT command is only good for connecting to another
669 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
671 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
672 or some other client was kicked from the channel.
674 Implemented the handling of the notify type to both client
677 Implemented silc_server_send_notify_kicked to send the KICKED
678 notify. It is used to send it to the server's primary router.
680 * Implemented the KICK command into server and client.
682 * Added `query' argument to the silc_idlist_get_client function
683 to indicate whether to query the client from server or not if
686 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
687 to indicate that the client is not channel founder.
691 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
693 * Removed the rng context from SilcPacketContext structure and
694 changed that the packet routine uses the Global RNG API.
696 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
698 * Added support for quit message that client can "leave" on the
699 channel when it quits the SILC. It is ditributed inside the
700 SILC_NOTIFY_TYPE_SIGNOFF notify type.
702 Added silc_server_free_client_data that will take the
703 signoff message as argument.
705 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
707 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
709 * Updated parts of the protocol specification to keep it up
712 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
714 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
715 payloads in one packet.
717 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
718 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
719 use now the new List flag.
721 * Also deprecated the following packet types: REPLACE_ID,
722 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
724 * Added list support for Notify packet in server.
726 * Added silc_server_send_notify_channel_change to send the
727 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
728 the silc_server_send_replace_id.
730 * Added silc_server_send_notify_nick_change to send the
731 NICK_CHANGE notify type. Deprecates the function
732 silc_server_send_replace_id.
734 * Added silc_server_send_notify_join to send the JOIN notify type.
735 Deprecates the function silc_server_send_new_channel_user.
737 * Added silc_server_send_notify_leave to send LEAVE notify type.
738 Deprecates the function silc_server_send_remove_channel_user.
740 * Added silc_server_send_notify_cmode and
741 silc_server_send_notify_cumode to send CMODE and CUMODE notify
742 types. Deprecates the silc_server_send_set_mode function.
744 * Added SERVER_SIGNOFF notify type to indicate that server has
745 quit. This means that all clients on the channel from that
746 server will drop. This can be also used when netsplit happens.
748 Deprecated REMOVE_ID packet type since it is not needed anymore
751 Added silc_server_send_notify_server_signoff to send the
752 SERVER_SIGNOFF notify type. Deprecates the function
753 silc_server_send_remove_id.
755 Added also silc_server_send_notify_signoff to send the
758 * Employed the PKCS #1. It is the mandatory way to do RSA in the
759 SILC protocol from this day on. Changed the protocol
760 specification as well.
762 * Added silc_server_send_notify_topic_set to send TOPIC_SET
763 notify type. It is used between routers to notify about
764 topic changes on a channel.
766 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
769 * Partly updated the protocol specification to comply with the
770 changes now made. It is still though a bit outdated.
772 * The JOIN notify type now takes one extra argument <Channel ID>.
773 The packet used to be destined to the channel but now the
774 JOIN type may be sent as list thus it is impossible to
775 destine it to any specific channel. By adding this argument
776 it is again possible.
778 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
780 * Added CREDITS file. The CHANGES and CREDITS file will appear
781 in the distribution as well.
783 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
785 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
786 types in the server's silcd/packet_receive.c.
788 * Implemented CMODE and CUMODE to work in router environment.
790 * Fixed minor encoding and decoding buglet from the
791 lib/silccore/silcmode.c.
793 * Fixed buffer overflow from lib/silcclient/command.c in USERS
796 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
798 * Changed all SilcConfigServer* and silc_config_server* to
799 SilcServerConfig* and silc_server_config*, respectively.
802 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
804 * Associated the ID (client or server ID) to the Authentication
805 Payload to avoid any possibility of forging. Updated the
806 protocol specification and the code accordingly.
808 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
810 * The RSA key length is now save to the RsaKey context in the
811 key generation process in lib/silccrypt/rsa.c. The key length
812 is now used to figure out the maximum size of the block allowed
813 to be encrypted/signed.
815 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
816 is equivalent to the silc_mp_mp2bin but does not allocate any
819 * Changed silc_mp_mp2bin API to take length argument. If it is
820 non-zero then the buffer is allocated that large. If zero, then
821 the size is approximated using silc_mp_sizeinbase, which however
824 * Created Global RNG API which is global RNG that application can
825 initialize. After initializing, any routine anywhere in the
826 code (including library) can use RNG without allocating a new
827 RNG object. This was done to allow this sort of use of the
828 RNG in code that has no chance to allocate RNG object. All
829 applications currently allocate this and many routines in the
830 library use this. Affected file lib/silccrypt/silcrng.[ch].
832 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
833 it to use the Global RNG API.
835 * Defined Authentication Payload into protocol specification that
836 is used during SILC session to authenticate entities. It is
837 used for example by client to authenticate itself to the server
838 to obtain server operator privileges.
840 Implemented this payload into the lib/silccore/silcauth.[ch].
841 Implemented also routines for public key based authentication
842 as the new protocol specification dictates.
844 Moved definitions of different authentication methods from
845 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
847 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
848 silc_pkcs_verify and silc_pkcs_sign_with_hash and
849 silc_pkcs_verify_with_hash functions into the file
850 lib/silccrypt/silcpkcs.[ch].
852 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
854 * The client entry's userinfo pointer must be always valid.
855 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
856 will fail since it requires the userinfo. Now, the userinfo
857 is allocated as "" if actual userinfo does not exist. Actually,
858 it must exist and it is totally Ok to drop client connections
859 that does not announce the userinfo. However, we will make
860 this workaround for now.
862 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
863 to return the remote port by socket.
865 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
867 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
868 SILC_SERVER_PENDING_EXEC and added an new macro
869 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
870 data or when error occurs while processing the pending command.
872 Added new argument `destructor' into silc_server_command_pending
873 and to the SilcServerCommandPending object. This destructor is
874 now called after calling the pending callback or if error occurs
875 immediately. If error occurs the actual pending callback won't
876 be called at all - only the destructor. The destructor may be
877 NULL if destructor is not needed.
879 All this applies for client library code as well. Similar
880 changes were made there as well for the pending commands.
882 In the client, the application must now allocate the
883 SilcClientCommandContext with the silc_client_command_alloc
886 * Added reference counter to the SilcServerCommandContext. Added
887 function silc_server_command_alloc and silc_server_command_dup
890 Same type of functions added to the client library for the same
893 * Removed the cmd_ident from IDListData away since it is now
894 global for all connections. It is the command identifier used
895 in command sending and with pending commands. The affected file
898 * Added reference counter to the SilcSocketConnection objecet to
899 indicate the usage count of the object. The object won't be
900 freed untill the reference counter hits zero. Currently only
901 server uses this, and client ignores it. The client must be
902 set to use this too later. The affected files are
903 lib/silccore/silcsockconn.[ch]. Added also the function
904 silc_socket_dup to increase the reference counter.
906 This was mainly added because it is possible that the socket
907 is removed underneath of pending command or other async
908 operation. Now it won't be free'd and proper DISCONNECTING
909 flags, etc. can be set to avoid sending data to connection that
910 is not valid anymore.
912 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
913 the connection. After that it sets SILC_SET_DISCONNECTED.
914 It is, however, possible that the socket data is not still freed.
915 The silc_server_packet_process now checks that data is not
916 read or written to connection that is DISCONNECTED. The socket
917 get's freed when the reference counter hits zero.
919 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
921 * Changed the client operation API: channel_message operation's
922 `sender' is now the client entry of the sender, not the nickname
923 and the `channel' is the channel entry, not the channel name.
925 In the private_message operation the `sender' is now also the
926 client entry of the sender not the nickname.
928 Affected file is lib/silcclient/ops.h and all applications
929 using the client operations.
931 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
933 * Moved the calling of ops->connect() from connect_to_server_final
934 into receive_new_id functin since that is the point when the
935 client is actually allowed to send traffic to network. The
936 affected file is lib/silcclient/client.c.
938 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
940 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
941 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
942 (if needs broadcasting) instead of broadcasting the packets one
943 by one which would make a burst in the network traffic.
945 * Added `broadcast' argument to the functions in silcd/server.[ch]
946 silc_server_create_new_channel[_with_id] to indicate whether
947 to send New Channel packet to primary router.
949 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
951 * Added new function into the silcd/server.[ch] files:
952 silc_server_create_new_channel_with_id to create new channel with
953 already existing Channel ID.
955 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
956 lib/silccore/silcpacket.h. This packet is used t send list of
957 Set Mode payloads inside one packet. Server uses this to set
958 the modes for the channels and clients on those channels, that it
959 announced to the router when it connected to it. The protocol
960 specification has been updated accordingly.
962 * The silc_server_new_channel did not handle the packet coming
963 from normal server as it normally does not send that. However,
964 when it announces its channels it does send it. Implemented
965 the support for that.
967 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
968 into the file lib/silccore/id.h.
970 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
972 * Fixed memory leaks in the functions silc_idlist_del_client,
973 silc_idlist_del_channel and silc_idlist_del_server in the file
974 silcd/idlist.c. All of those leaked like a sieve.
976 * Fixed some small memory leaks in the client's function
977 silc_client_notify_by_server.
979 * Added functions into silcd/server.c: silc_server_announce_clients,
980 silc_server_announce_channels and silc_server_announce_server.
981 These functions are used by normal and router server to announce
982 to its primary router about clients, channels and servers (when
983 router) that we own. This is done after we've connected to the
986 These functions effectively implements the following packet types:
987 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
988 and SILC_PACKET_NEW_ID_LIST.
990 * Added new functions into the silcd/packet_receive.[ch]:
991 silc_server_new_id_list, silc_server_new_channel_list and
992 silc_server_new_channel_user_list to handle the incoming
993 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
995 * Added support of changing Channel ID in the function
996 silc_server_replace_id. If the server that announces a channel
997 to the router already exists in the router (with same name but
998 with different Channel ID), router is responsible to send
999 Replace ID packet to the server and force the server to change
1000 the Channel ID to the one router has.
1002 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1003 client that the Channel ID has been changed by the router. The
1004 normal server sends this to the client. Client must start using
1005 the new Channel ID as the channel's ID.
1007 Implemented handling of this new type into lib/silcclient/client.c
1008 into the function silc_client_notify_by_server.
1010 * Added new function silc_idlist_replace_channel_id into the files
1011 silcd/idlist.[ch] to replace the Channel ID.
1013 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1015 * Call silc_server_command_identify_check always when processing
1016 the IDENTIFY command in silcd/command.c
1018 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1020 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1021 send keepalive packets. The packet can be sent by clients,
1022 servers and routers.
1024 Added function silc_socket_set_heartbeat into the file
1025 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1026 If not set, the heartbeat is not performed. The actual
1027 heartbeat is implemented in the low level socket connection
1028 library. However, application is responsible of actually
1031 Added silc_server_send_heartbeat to send the actual heartbeat
1032 packet into silcd/packet_send.[ch]. Server now performs
1033 keepalive with all connections.
1035 * Added silc_task_get_first function into lib/silcutil/silctask.c
1036 to return the timeout task with shortest timeout. There was a bug
1037 in task unregistration that caused problems. TODO has been
1038 updated to include that task system must be rewritten.
1040 * The client library will now resolve the client information when
1041 receiving JOIN notify from server for client that we know but
1042 have incomplete information.
1044 * Rewrote parts of silc_server_remove_from_channels and
1045 silc_server_remove_from_one_channel as they did not remove the
1046 channel in some circumstances even though they should've.
1048 * Encryption problem encountered in server:
1050 The LEAVE command used to send the Channel Key packet to the
1051 router immediately after generating it. However, the code
1052 had earlier sent Remove Channel user packet but not immediately,
1053 ie. it was put to queue. The order of packets in the router
1054 was that Channel Key packet was first and Remove Channel User
1055 packet was second, even though they were encrypted in the
1056 reverse order. For this reason, MAC check failed. Now, this
1057 is fixed by not sending the Channel Key packet immediately but
1058 putting it to queue. However, this is more fundamental problem:
1059 packets that are in queue should actually not be encrypted
1060 because packets that are sent immediately gets encrypted
1061 actually with wrong IV (and thus MAC check fails). So, packets
1062 that are in queue should be encrypted when they are sent to
1063 the wire and not when they put to the queue.
1065 However, the problem is that the current system has not been
1066 designed to work that way. Instead, the packet is encrypted
1067 as soon as possible and left to the queue. The queue is then
1068 just purged into wire. There won't be any fixes for this
1069 any time soon. So, the current semantic for packet sending
1072 o If you send packet to remote host and do not force the send
1073 (the packet will be in queue) then all subsequent packets to the
1074 same remote host must also be put to the queue. Only after the
1075 queue has been purged is it safe again to force the packet
1078 o If you send all packets immediately then it safe to send
1079 any of subsequent packets through the queue, however, after
1080 the first packet is put to queue then any subsequent packets
1081 must also be put to the queue.
1083 Follow these rules and everything works fine.
1085 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1087 * Added new function silc_server_remove_clients_by_server to
1088 remove all client entries from ID list when the server connection
1089 is lost. In this case it is also important to invalidate all
1090 client entires as they hold the invalid server entry. This
1091 fixes fatal bug when server has lost connection and will reconnect
1094 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1096 * Made some sanity checks to silc_server_daemonise like to check
1097 whether the requested user and group actually exists.
1099 * Added sanity check to SKE's silc_ske_responder_finish to check
1100 that the public and private key actually is valid.
1102 * Invalidate the client's nickname when receiving Replace ID
1103 packet and the Client ID is being replaced. This means that the
1104 server will query the nickname if someone needs it (client)
1107 * Sort the ID Cache in client library when the ID Cache data
1108 has changed (needs sorting).
1110 * Do not allow for SILC client to create several connections to
1111 several servers. The client does not support windows right now
1112 and generating multiple connections causes weird behaviour.
1114 Irssi-silc client does support windows and can handle several
1115 connections without problems, see: www.irssi.org and SILC plugin.
1117 * Fixed some places where client was added to the IDList. The
1118 rule of thumb is following (in order to get everything right):
1119 If the client is directly connected local client then the
1120 `connection' argument must be set and `router' argument must be
1121 NULL to silc_idlist_add_client function. If the client is not
1122 directly connected client then the `router' argument must
1123 bet set and the `connection' argument must be NULL to the
1124 silc_idlist_add_client function.
1126 * The funtion silc_server_packet_send_local_channel actually did
1127 not check whether the client was locally connected or not. It
1128 does that now. Fixed a bug related to LEAVE command.
1130 * Fixed Remove Channel User payload parsing bug in server's
1131 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
1133 * The server's silc_server_save_channel_key now checks also the
1134 global ID list for the channel as it might not be in the local
1135 list. Fixed a bug related to LEAVE command.
1137 * Is this the end of the [<unknown>] buglet that has been lurking
1138 around for a long time? A little for loop fix in server's
1139 silc_server_command_whois_parse that is used by both IDENTIFY
1140 and WHOIS command. At least, this was a clear bug and a cause
1141 of one type of [<unknown>] buglet.
1143 * WHOIS and IDENTIFY commands call the function
1144 silc_server_command_[whois/identify]_check function even if
1145 we are not router server.
1147 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1149 * Added --with-gmp configuration option. If set the GMP
1150 is always compiled in the SILC source tree. If not set then
1151 it is checked whether the system has the GMP3 installed. If
1152 it has then the GMP won't be compiled (the system's headers
1153 and library is used), if it doesn't have it then the GMP is
1154 compiled in the SILC source tree.
1156 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1158 * Changed RSA private exponent generation to what PKCS #1
1159 suggests. We try to find the smallest possible d by doing
1160 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
1161 not security fix but optimization.
1163 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1165 * Added new config entry [Identity] to fork the server and run
1166 it as specific user and group. A patch from Bostik.
1168 * Imported Dotconf configuration library into lib/dotconf.
1169 This will be used to create the SILC configuration files later.
1170 It will appear in the distsribution after this commit.
1172 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1174 * A big code auditing weekend happening. Auditing code for
1175 obvious mistakes, bugs and errors. Also, removing any code
1178 Removed files for being obsolete:
1180 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
1181 inline in the file lib/silcutil/silcbuffer.h)
1183 o lib/silcutil/silcbufutil.c (the header has inline versions)
1185 Changed code to fix possible error conditions:
1187 o The buffer formatting routines now check that the destination
1188 buffer really has enough space to add the data. This applies for
1189 both buffer formatting and unformatting
1190 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
1191 unformatting was changed to accomodate following rules:
1192 XXX_*STRING_ALLOC will allocate space for the data into the pointer
1193 sent to the function while XXX_*STRING will not allocate or copy
1194 the data into the buffer. Instead it sets the pointer from the
1195 buffer into the pointer sent as argument (XXX_*STRING used to
1196 require that the pointer must be allocated already). This change
1197 makes this whole thing a bit more consistent and more optimized
1198 (note that the data returned in the unformatting with XXX_*STRING
1199 must not be freed now). The routines return now -1 on error.
1201 o Tried to find all code that use buffer_format and buffer_unformat
1202 and added return value checking to prevent formatting and
1203 especially unformatting errors and possible subsequent fatal
1206 o Changed ske->x and ske->KEY to mallocated pointers in
1207 lib/silcske/silcske.h. Fixed possible data and memory leak.
1209 o Added return value checking to all *_parse* functions. Fixed
1210 many memory leaks as well.
1212 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1213 so that buffer overflows would not happen. All code now also
1214 checks the return value as it can fail.
1216 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1218 * Added reconnection support to server if the normal server looses
1219 its connection to the router (for example if router is rebooted).
1220 The server performs normal reconnection strategy implemented
1221 to the server. Affected file silcd/server.c.
1223 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1225 * Added new packet type SILC_PACKET_SET_MODE that is used to
1226 distribute the information about changed modes (for clients,
1227 channels and clients channel modes) to all routers in the
1228 network. Updated the protocol specification accordingly.
1230 Added functions into silcd/packet_send.c and
1231 silcd/packet_receive.c: silc_server_send_set_mode,
1232 silc_server_set_mode.
1234 Added new files silcmode.[ch] into lib/silccore that implements
1235 the encoding and decoding of Set Mode Payload. Added new type
1236 SilcSetModePayload. Moved the definitions of different modes
1237 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1239 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1241 * Oops, a little mistake in server's connection authentication
1242 protocol. The protocol is not ended with FAILURE but with
1243 SUCCESS if the authentication is Ok. :) Affected file is
1246 * Implemented NICK_CHANGE notify handling in server in the file
1247 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1248 the local clients on the channel. After the changing nickname
1249 in router environment snhould work and the [<unknown>] nickname
1250 should appear no more.
1252 The silc_server_replace_id function that receives the Replace ID
1253 payload now sends the NICK_CHANGE notify type also in the file
1254 silcd/packet_receive.c
1256 * Changed WHOIS and IDENTIFY command to support the maximum amount
1257 of arguments defined in protocol specs (3328 arguments). This
1258 fixed a bug that caused problems when there were more than three
1261 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1263 * Added extra parameter, command identifier, to the
1264 silc_client_send_command so that explicit command identifier
1267 Changed that ID list routines uses specific command identifier
1268 when sending WHOIS/IDENTIFY requests to the server so that they
1269 can be identified when the reply comes back.
1271 Affected files lib/silcclient/command.[ch],
1272 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1274 * Added `sender' argument to silc_server_packet_send_to_channel
1275 to indicaet the sender who originally sent the packet to us
1276 that we are now re-sending. Ignored if NULL. Affected file
1277 silcd/packet_send.[ch].
1279 * Added some server statistics support in silcd/server_internal.h
1280 SilcServerStatistics structure and around the server code. Also
1281 send some nice statistics information when client is connecting
1284 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1286 * Fixed channel ID decoding in server's JOIN command reply in
1287 silcd/command_reply.c
1289 * Fixed braodcasting of replace ID payload to not to send it if
1290 we are standalone server in silcd/packet_receive.c.
1292 * Fixed all channel message sending routines to not to send
1293 packets to clients that has router set, since they are routed
1294 separately in the same function earlier. Affects file
1295 silcd/packet_send.c and all channel packet sending functions.
1297 * In USERS reply, res_argv[i] are not allocated, the table
1298 is allocated. Thus changed that free the table, not its
1301 * In server's whois_check and identify_check if the client is
1302 locally connected do not send any WHOIS commands - they are not
1305 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1307 * Fixed some minor bugs in client when sending WHOIS command. The
1308 arguments was in wrong order.
1310 * Removed statis function add_to_channel from server in
1311 silcd/command.c that was previously used with the joining but
1314 * Tested USERS command in router environment successfully with two
1315 routers, two servers and two clients.
1317 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1319 * Reorganized the USERS command and command reply in client library
1320 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1321 When the command is given by user we register a pending command
1322 callback that will reprocess the command after the reply has been
1323 received from the server. When reprocessing the packet we then
1324 display the information. Thus, the USERS information is displayed
1325 now in the command callback instead of in the command reply
1326 callback. The processing of the command is same as previously
1327 when server has sent the command reply in the JOINing process.
1329 * Added to USERS command in silcd/command_reply.c to join the client,
1330 we didn't use to know about, to the channel after we've created
1331 a client entry for it. Also, for clienet we did know already still
1332 check whether it is on the channel or not and add it if not.
1334 * Removed silc_server_command_join_notify as the function and its
1337 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1339 * Changed the client's pending command handling to the same as the
1340 server's pending command handling. It is also now possible to
1341 execute command reply functions from other command reply
1342 function as the function callbacks for commands and command
1343 replies are one and same. The pending commands are not static
1344 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1345 in client connection context. Thus, pending commands are server
1346 connection specific as it is convenient.
1348 Changed the function silc_client_command_pending and
1349 silc_client_command_pending_del and added new function
1350 silc_client_command_pending_check. Removed the
1351 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1354 * Added cmd_ident, current command identifier, to the client
1355 connection context in lib/silcclient/client.h to keep track on
1356 command identifiers used in command sending. Client's command reply
1357 function handling now supports the mandatory command identifiers.
1359 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1360 funtions in client to fully support pending command callbacks.
1362 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1363 as one of the arguments to the application in the command reply
1366 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1367 before first releasing SILC but came back. Now it is removed again
1368 and should come back nomore. The FORWARDED flag was used only
1369 by the JOINing procedure by forwarding the command packet to router.
1370 Now, the JOINing procedure has been changed to more generic (due
1371 to various router environment issues) and FORWARDED is not needed
1372 anymore for anything. The protocol specification is yet to be
1375 Now, removed silc_server_packet_forward from server and the flag
1376 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1378 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1380 * Renamed NAMES command to USERS command. The NAMES was named that
1381 due to historical reasons. Now it is renamed. Also, rewrote
1382 parts of the USERS command. The nickname list is not sent anymore
1383 by the server. Only Client ID and mode lists are sent in the USERS
1384 command. Changed this also to the protocol specification.
1386 The client now resolves the names and stuff after it receives
1387 the USERS list from the server when joining to the channel.
1389 * WHOIS and IDENTIFY commands has been changed to support multiple
1390 Client ID's per command. One can now search for multiple users
1391 in the network by sending only one WHOIS or IDENTIFY command.
1392 Changed the code and the protocol specifications.
1394 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1395 uses silc_server_command_whois_parse to parse the request. */
1397 * If normal server, do not parse the WHOIS and IDENTIFY requests
1398 before sending it to the router. Saves some time.
1400 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1402 * Fixed JOIN command on client library. Wrong number of arguments
1403 used to crash the client.
1405 * Added silc_server_channel_has_global function to check whether
1406 channel has global users or not.
1408 * Added silc_server_channel_has_local function to check whether channel
1409 has locally connected clients on the channel.
1411 * The silc_server_remove_from_one_channel now checks whether the
1412 channel has global users or not after given client was removed from
1413 the channel. It also checks whether the channel has local clients
1414 on the channel anymore. If it does not have then the channel entry
1415 is removed as it is not needed anymore.
1417 * The silc_server_notify now checks on JOIN notify whether the joining
1418 client is one of locally connected or global. If it is global then
1419 the channel has now global users on the channel and that is marked
1420 to the channel entry. Also, it now saves the global client to
1421 global list who is joining and JOINs it to the channel. This is
1422 for normal server, that is.
1424 Changed silc_server_send_notify_on_channel,
1425 silc_server_packet_relay_to_channel and
1426 silc_server_packet_send_to_channel check if we are normal server
1427 and client has router set (ie. global client) do not send the
1428 message to that client, as it is already routed to our router.
1430 * Implemented LEAVE notify type handling in silc_server_notify
1433 * Tested LEAVE command in router environment successfully. Tested
1434 with two routers, two servers and two clients.
1438 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1440 * Implemented SIGNOFF notify type handling in silc_server_notify
1443 * silc_server_remove_id now removes the client entry from all channels
1444 it has joined and thusly sends SIGNOFF notify type.
1446 * Rewrote the NAMES list generation in server by removing two excess
1447 loops. The lists are created now inside one loop.
1449 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1451 * silc_server_remove_channel_user checks now also global list
1452 for channel and client.
1454 * silc_server_new_channel_user checks now both local and global
1455 list for channel and client. Fixed a bug in client id decoding.
1456 Used to decode wrong buffer.
1458 * silc_server_channel_message checks now both local and global
1459 list for channel entry.
1461 * Tested channel joining (hence JOIN) in router environment
1462 successfully. Tested with two routers, two servers and two
1465 * Tested channel message sending in router environment successfully.
1467 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1469 * Added silc_server_save_channel_key into server.[ch] to save the
1470 received channel key in Channel Key payload processing. It is
1471 also used in JOIN command reply handling.
1473 Equivalent function silc_client_save_channel_key added into
1474 client.[ch] into client library.
1476 * Changed JOIN command reply to send information whether the channel
1477 was created or not (is existing already) and the channel key
1478 payload. Changed protocol specs accordingly.
1480 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1481 the request was sent by ID and not by nickname. Crashed on
1484 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1486 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1487 now correctly save the received data.
1489 * silc_server_free_sock_user_data now notifies routers in the
1490 network about entities leaving the network.
1492 At the same time implemented functions silc_server_remove_id
1493 and silc_server_send_remove_id to receive and send REMOVE_ID
1494 packets. The packet is used to notify routers in the network
1495 about leaving entities. The ID removed will become invalid in
1498 * Added function silc_idlist_del_server into server. Removes and
1499 free's server entry from ID list.
1501 * silc_server_private_message function now checks, if we are router,
1502 that the destination ID really is valid ID, naturally.
1504 * In router when NEW_ID packet is received (for new client) the
1505 hash of the Client ID is saved in the ID Cache but the
1506 client->nickname is set to NULL, instead of putting the hash
1509 IDENTIFY command now also checks that client->nickname must be
1510 valid. If it is not if will request the data from the server who
1511 owns the client. Added new function
1512 silc_server_command_identify_check.
1514 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1515 to set the command to already allocated Command Payload.
1517 * Tested private message sending in router environment with two
1518 routers, two servers and two clients. Fixed minor bugs and now
1521 * Fixed segfault from client's NAMES command. Used to crash if
1524 * Forwarded packets must not be routed even if it is not destined
1525 to the receiver. Changed server code comply with this.
1527 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1529 * Added `require_reverse_mapping' boolean value to ServerParams
1530 structure. If TRUE (not default) the server will require that
1531 the connecting host has fully qualified domain name.
1533 If the reverse mapping is not required and hostname could not be
1534 found the IP address is used as hostname.
1536 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1538 * Implemented version string checking to both client and server.
1539 The check is incomplete currently due to the abnormal version
1540 strings used in development version of SILC.
1542 * Changed all command functions in server to use the new
1545 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1547 * Changed char *data to unsigned char *data in ID Cache system to
1548 support binary data as ID Cache data. Changed code to support
1549 binary data in lib/silccore/idcache.c.
1551 * Renamed silc_server_packet_relay_command_reply to
1552 silc_server_command_reply as it is normal packet receiving
1553 function. Rewrote the function to accept command replys for
1554 servers and not only for clients.
1556 * Mark remote router always as registered server if we are connecting
1557 to it. Otherwise, commands sent by the router to us are ignored.
1559 * All ID List find routines now returns the ID Cache Entry pointer
1560 as well if requested.
1562 * WHOIS command works now in router environment, tested with two
1563 routers, two servers and two clients.
1565 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1566 in router environment (as it is almost equivalent to WHOIS) but
1567 hasn't been tested thoroughly. Added new functions:
1569 silc_server_command_identify_parse
1570 silc_server_command_identify_send_reply
1571 silc_server_command_identify_from_client
1572 silc_server_command_identify_from_server
1574 * Disabled route cache adding because adding two different ID's with
1575 same IP replaces the old cache entry thus giving wrong route.
1576 The entry->router->connection is always the fastest route anyway
1577 so route cache may not be needed. Of course, new routes maybe
1578 established after receiving the ID when the entry->router->connection
1579 might not be anymore the most optimal.
1581 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1583 * Add route cache for received ID for fast routing.
1585 * Added silc_server_packet_route to route received packet on router
1586 that is not destined to us.
1588 * Renamed silc_server_get_route to silc_server_route_get.
1590 * Added id_string and id_string_len fields into SilcServer to
1591 include encoded ServerID for fast comparing without excess
1592 encoding of the ID's.
1594 * Cleaned up WHOIS command on server side. Added following static
1597 silc_server_command_whois_parse
1598 silc_server_command_whois_check
1599 silc_server_command_whois_send_reply
1600 silc_server_command_whois_from_client
1601 silc_server_command_whois_from_server
1603 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1604 arguments in command replies. All command functions should be
1605 updated to use this macro.
1607 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1609 * Minor typo fixes on command reply handling on server.
1611 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1613 * Added silc_server_command_add_to_channel internal routine to add
1614 the client to the channel after router has created the channel and
1615 sent command reply to the server.
1617 * Added generic silc_server_send_command to send any command from
1620 * Use static buffer with ID rendering instead of duplicating data.
1622 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1624 * Fixed a channel user mode bug when joining to a channel server gave
1625 everybody channel founder rights, oops.
1627 * We mark ourselves as the router of the incoming server connection
1628 if we are router ourselves. This way we can check in some packet
1629 sending functions whether it is locally connected server. For
1630 incoming router connections we put NULL.
1632 * For router sending packets locally means now always sending the
1633 packet cell wide; to local clients and local servers. For normal
1634 server sending packet locally means sending it to only local
1637 * Fixed the JOIN command to really work in router environment. If the
1638 channel is created it is always created by the router. Router is
1639 also responsible of making the initial joining to the channel,
1640 sending JOIN notify to the sending server and distributing
1641 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1642 does not exist server doesn't do anything else but forward the
1643 command to the router which performs everything.
1645 * Added silc_server_send_channel_key function to send the Channel Key
1648 * Added silc_server_create_channel_key to create new channel key. The
1649 channel key is now re-generated everytime someone joins or leaves
1650 a channel, as protocol dictates. Note: channel->key_len is the
1653 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1655 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1656 packet_receive.[ch] to separate packet sending and receiving
1657 routines. The server.[ch] now includes everything else including
1658 actual packet processing (writing and reading data) and other
1661 Renamed silc_server_private_message_send_internal to
1662 silc_server_send_private_message. The routine is still though
1663 used only to relay private messages as server does not send
1664 private messages itself.
1666 Renamed silc_server_new_channel to silc_server_create_new_channel
1667 and added new function sicl_server_new_channel that handles the
1668 incoming New Channel packet. Added also new sending function
1669 silc_server_send_new_channel to send New Channel Payload.
1671 * Added new function silc_server_notify to process incoming notify
1672 packet to the server/router. Server may then relay the notify
1673 to clients if needed.
1675 * Added new function silc_server_new_channel_user to process incoming
1676 New Channel User packet. Router will redistribute the packet and
1677 send JOIN notify to its local clients and locally connected servers
1678 if needed. Normal server will send JOIN notify to its local client
1679 on same channel when received this packet. Added also corresponding
1680 sending function silc_server_send_new_channel_user to sent the
1683 * Added boolean route argument to send_notif_to_channel and
1684 packet_send_to_channel functions to attempt to route the packet
1685 if it is TRUE and send only locally if it is FALSE.
1687 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1689 * silc_server_replace_id now broadcasts the received replace ID
1690 packet if it is not broadcast packet already. The router must
1691 broadcast to inform other routers about changed ID.
1693 * Added backpointer to server's router into SilcServer context in
1694 silcd/server_internal.h.
1696 * Fixed silc_server_packet_broadcast to send correct broadcast
1699 * The channel key is now distributed to the local client as soon
1700 as it is received from the router (in router environment) so that
1701 no other packet may be sent for the channel until client has
1704 * silc_server_remove_channel_user now broadcasts the received
1705 Remove Channel User packet if it is not broadcast packet already.
1706 The router must broadcast to inform other routers about removed
1709 * Added users field into SilcPacketContext that is a reference count
1710 of the context. One can increase the reference count by calling
1711 silc_packet_context_dup which is now changed to just increase the
1712 reference count instead of duplicating the data. The reference
1713 count is decresed by calling silc_packet_context_free that will
1714 free the data after the reference count hits zero.
1716 For now on the packet context and everything allocated into it
1717 (including the raw packet from network) must be freed by calling
1718 the new silc_packet_context_free function. Added also new function
1719 silc_packet_context_alloc that must be used now to allocate the
1720 context. This also means that if a routine is asynchronous from
1721 silc_[client/server]_packet_parse_type the packet context must
1722 be duplicated by calling silc_packet_context_dup. Otherwise it
1723 gets free'd after silc_[client/server]_packet_parse_type returns.
1724 Also, one must remember that if packet is duplicated then its
1725 reference count must be decresed by calling the free function as
1726 many times as it was duplicated.
1728 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1729 from both client and server.
1731 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1733 * Made joining to a channel working in router environment.
1735 * Cleaned up JOIN command on server side and create function
1736 silc_server_command_join_channel internal routine to make the
1739 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1741 * Changed silc_command_pending list to SilcDList. Also, added
1742 `ident' field to SilcServerCommandPending structure to identify
1743 the reply and to call correct callback.
1745 Added silc_server_command_pending_check function to replace the
1746 corresnponding macro. The silc_command_pending list is not
1749 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1750 to set identifier to previously allocated Command Payload. It
1751 is used to set identifier for command when resending Command
1754 * Added silc_command_payload_encode_payload to encode Command
1755 Payload buffer from SilcCommandPayload structure.
1757 * Added silc_argument_payload_encode_payload to encode Argument
1758 payload buffer from SilcArgumentPayload structure.
1760 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Changed WHOIS command to support router connection on server side.
1763 The whois request is always sent to router unless the server is
1764 standalone server. After server has received the reply from the
1765 router will it send the reply to the client.
1767 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1768 broadcast received broadcast packet. The function is used only
1769 by router. The broadcast packet is always sent to the router's
1772 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1773 render given ID to printable string, for log files for example.
1775 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1777 * Made basic router to router connections working. At least they
1778 can now connect to each other but nothing really works the way
1779 they are supposed - yet.
1781 * Added new initiator token to RouterConnection configuration
1782 file in silcd/serverconfig.[ch]. It is used to tell whether we
1783 are the initiator to the remote router or whether we'll expect
1784 the other end to connect.
1786 * Moved registering of listener task to silc_server_init, hence
1787 the server starts listenning as soon as it is run, even if it
1788 does not have connections to other routers. Let's see how well
1791 * Changed default connection retry timeouts for more suitable in
1794 * Removed cipher and such arguments from silc_idlist_add_client
1795 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1796 Added new function silc_idlist_add_data to add the keys and stuff
1799 * Added SilcIDListData structure and added it to SilcClientEntry
1800 and SilcServerEntry as their first field in the structure. This
1801 way we can explicitly cast the ID entries to the SilcIDListData
1802 structure and get common data for the entries. In past, we had
1803 to first check what type of connection it is and then cast it to
1804 correct ID entry type. Now, we can directly cast the opaque
1805 pointer to the SilcIDListData (no matter what ID entry it actually
1806 is) and get the data needed.
1808 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1810 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1811 in some circumstances even if threre were timeout tasks, though not
1812 IO tasks, but tasks anyway. Now fixed.
1814 * Defined SilcServerConnection structure to hold connection specific
1815 stuff about directly connected servers and routers. The definition
1816 is currently in silcd/server_internal.h. I thought about having
1817 a bit more important role fro this struct but for now it is used
1818 only when connecting to other server (or router actually).
1820 * Added connecting retry support in server when connecting to
1821 router(s). The retry feature implement exponential backoff
1822 algorithm. Also, added SilcServerParams structure to hold default
1823 parameters for server. For now, it include these retry settings
1824 and are hard coded. After server is moded to be as Silc Server
1825 Library this structure will be more important.
1827 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1829 * Changed client librarys channel->clients table to SilcList and
1830 changed code accordingly.
1832 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1834 * Changed client's channel table to SilcList and changed code
1835 accordingly. Also changed SilcChannelClientEntry to include back-
1836 pointer to the channel so that client entry can use that structure
1837 as list as well and we have fast cross-reference to the channel.
1838 This change dramatically decreased the complexity of channel
1839 handling with client entry and vice versa (removed one extra
1840 loop when searching for channel entry from many functions).
1842 * Changed server->sim from table to SilcDList and changed code
1845 * NAMES command can now be used from user interface. It will show
1846 the user list on the channel, neatly.
1848 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1849 Code now saves realname of the user if it becomes available.
1851 * Renamed configure.in to configure.in.pre and made ./prepare
1852 script to automatically add correct version string to
1853 configure.in which it creates from configure.in.pre.
1855 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1857 * NAMES command reply now shows users mode with the nickname when
1860 * Moved silc_client_ch[u]mode[_char] functions from
1861 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1862 place sucks, they are utility functions and should be in some
1865 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1867 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1870 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1874 * Added TRQ (efficient deque and list library) into lib/trq. This is
1875 a very good list library that is currently used in the SILC. Defined
1876 SilcList API over the library because I didn't like the API very
1877 much. See lib/trq/silclist.h for the API and examples of how to
1878 use the API. Fixed various places in the code to use the new
1879 SilcList API. The SilcList is meant for lists that has a structure
1880 already defined as a list. It is not suitable to add just some
1881 context to the list (in TRQ, the context is the list actually).
1883 So, I defined SilcDList that can be used for the purpose where
1884 predefined list structure does not exit. This can be used as
1885 such list. Now some context just can be added to the SilcDList.
1886 Currently this list is not used in the SILC just yet, though there
1887 are a lot places where this can replace dynamically allocated
1888 tables and I will fix these places, later, to use SilcDList.
1889 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1890 and use TRQ internally).
1892 Also fixed some annoying warning messages that the original TRQ
1893 code generated. Also minor changes to TRQ's Makefile.in.
1895 * Added support for querying by Client ID to both WHOIS and
1896 IDENTIFY commands into server, as required by the protocol.
1898 * Removed method function pointers from SilcBuffer structure. They
1899 weren't used to anything and just increased the context size for
1900 no good reason. This change also made silc_buffer_alloc and
1901 silc_buffer_free functions inline functions.
1903 * Disabled command flooding detection support until it's fixed so
1904 that it accepts commands in but does not execute them more than once
1907 * Added silc_net_localhost(), to return local hostname, into
1908 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1909 that must be initialized before calling silc_client_init.
1911 * Added new function: silc_server_send_notify_on_channels to send
1912 notify messages to all channels client has joined. It is assured
1913 that the message is sent only once per client.
1915 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1916 lib/silcutil/silcutil.[ch] as silc_format function. The new
1917 function is generic and is used by server as well, not only by
1918 the logging routines.
1920 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1921 the provided version string was not acceptable. Added new function:
1922 silc_ske_check_version into lib/silcske/silcske.h. The function
1923 must be implemented by the application (client or server) and it
1924 does not reside in the SKE library. The function checks the version
1925 string remote end sent.
1927 * Added back pointers (to opaque context and to SilcSocketConnection)
1928 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1930 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1931 duplicate packet context structure.
1933 * Changed `notify' client operation to send same arguments as client
1934 receives from server except for ID's. ID's are mapped to correct
1935 ID entry and that is returned. Also, if channel entry is not sent
1936 by server but the notify is for channel the channel entry is sent
1937 to application (otherwise application doesn't know that it is for
1938 channel (library gets it from packet's Destination ID)).
1940 * Added silc_client_remove_from_channels into client library to
1941 remove a client from all channels it has joined to. Used when
1942 received SIGNOFF notify from server. Added also new function
1943 silc_client_replace_from_channels to replace old ID entry with
1944 new ID entry on all channels. Used when received NICK_CHANGE
1947 * Fixed ID Cache list handling in silc_idlist_get_client in
1948 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1949 to get (or query) client by ID.
1951 * Updated TODO list.
1953 * Added connection authentication status message defined by the
1954 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1955 support for these into the code in client and server side.
1957 * Added generic function silc_client_send_command to send any command
1958 with variable argument list. Application should use this function
1959 to send commands if the command functions provided by the library
1960 does not suite for the application's user interface needs.
1962 * Added new `failure' client operation. Application is notified about
1963 received failure packet if client is executing a protocol. In this
1964 case the protocol's execution has failed.
1966 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1967 is required by the protocol.
1969 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1970 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1973 * Added status flag to SilcSKE object to indicate realtime status
1974 of the SKE protocol.
1976 * Application receives now exactly same command reply arguments as
1977 the library receives from server. However, if ID is received the
1978 corresponding ID entry is returned to the application (eg. Client
1979 ID is mapped to correct SilcClientEntry entry and that is returned).
1980 Changed command_reply client operation due to this change.
1982 * Changed all ID's in commands and in command replys as ID Payloads.
1983 Change affected both client and server side codes.
1985 All ID's sent in SILC network (with execption of ID's in SILC
1986 Packet header) are sent in ID Payload to support variable length
1989 * Server now notifies nick changes and notifies all clients on
1990 the channels about the new nickname (about the new Client ID,
1993 * Implemented CMODE command to change channel modes. Supports all
1994 channel modes defined by the protocol specs except ban and invite
1995 lists. (Also, private channel key mode is supported but support for
1996 setting private channel key in client is missing, thus, this mode
1997 has no effect on client side (except that server requires that the
1998 client uses private channel key and normal channel traffic does not
2001 Also, invite mode works per se, but INVITE command does not work
2002 yet correctly, so you can set channel as invite only channel but
2003 inviting clients to the channel does not work (it is yet to be
2004 thought what's the best way to do it).
2006 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2007 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2008 Implemented CUMODE command to change user's mode on the channel.
2009 Supports all modes defined by the protocol specs.
2011 * Added NAMES command reply to return users modes on the channel.
2013 * Removed unnecessary and slow ciphers from lib/silccrypt.
2015 * Set SO_KEEPALIVE option to connection sockets by default.
2017 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2019 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2020 redefined the Notify Payload into protocol specs.
2022 * Added silc_id_payload_parse_id to get ID directly from raw
2025 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2027 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2028 accept searching by Client ID as well.
2030 * Added support for LEAVE and SIGNOFF notify types in client library.
2032 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
2033 to parse ID Payload from raw data.
2035 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2037 * Added flags parameter into silc_ske_assemble_security_properties
2038 function in lib/silcske/silcske.[ch].
2040 * Changed notify client operation to fit better for notify messages
2041 sent by server. The notify payload received from server is now
2042 passed to the application (after parsing it to SilcNotifyPayload).
2043 It is application's responsibility to retrieve the arguments
2044 from the payload and show the message the way it wants. The message
2045 sent by server is implementation specific.
2047 * Changed public keys to comply with the protocol specification.
2048 Old public keys are not supported anymore and are not compatible.
2050 * Removed nickname from Channel Payload as the latest draft removed
2051 it. The client must resolve the nickname from the NAMES command
2052 reply received when it joined the channel.
2054 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
2056 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2058 * Fixed some errors in protocol specification drafts.
2060 * Created lib/silccore/silcnotify.c to implement Notify Payload
2061 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
2062 generic payloads described by protocol specifications. The file
2063 includes implementations for ID Payload and Argument Payload.
2065 * Changed Command Payload implementation to use the new Argument
2066 Payload. Changed command_xxxx_payload to command_payload_xxxx
2067 to comply with SILC coding conventions.
2069 * Added suppport for Argument Payload handling in Notify Payload
2070 implementation as protocol requires it. Added the new support
2071 into server and client lib as well.
2073 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2075 * Added support for multiple nicknames on same channel. [n] is
2076 added locally to the nickname if there are more than one same
2077 nicknames on the channel.
2079 * Server now sends all nicknames that matched WHOIS request.
2080 Client also shows the list received from server.
2082 * Added TOPIC command to client side. User can now set and show
2083 current topic on channel.
2085 * Added MOTD command to client and server. Also, server sends the
2086 motd when client connects to the server.
2088 * Changed version strings to comply ISO 8601.
2090 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2092 * Fixed protocol error handling in client library. It should now
2093 cope even if the SKE fails for some reason.
2095 * Made new protocol specification drafts for submitting to IETF.
2097 * Implemented TOPIC command to server in silcd/command.c.
2099 * Added two new notify types into lib/silccore/silcnotify.h:
2100 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
2101 notify nickname change and topic setting/change on a channel.
2103 * API change of command_reply operation in client library. The
2104 application gets now the status type received from server as well.
2106 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2108 * Removed the function just added to lib/silcutil/silcschedule.[ch].
2110 * Cras fixed and optimized the packet handling even further and
2111 it should work now. Minor change to the prototype of function
2112 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
2114 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2116 * Added new function into lib/silcutil/silcschedule.[ch]:
2117 silc_schedule_with_fd to select() a specified fd. The function
2118 returns after timeout expires or data arrives or goes. The
2119 function is used by packet routines to wait that all data is
2120 received from network.
2122 * Fixed data reading from network in lib/silccore/silcpacket.c.
2123 The code now assures that all data is read from the fd and then
2124 continues packet processing. This was a bug fix since the code
2125 used to drop some data in some circumstances.
2127 * Added new function into lib/silcclient/client.[ch]:
2128 silc_client_start_key_exchange to start key exchange after
2129 connection has been established to server. The code internally
2130 now uses this funtion but its main purpose was to provide it
2131 for applications that perform their own connecting. After
2132 application has created a connection it merely calls this
2133 function to start the key exchange between client and server.
2134 The library takes care of everything else after that.
2136 Updated also lib/silcclient/README to explain the usage of
2139 * Do not send to application information that connection has
2140 been established. Application gets notified it by connect
2143 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2145 * Applied cras's patch to add silc_schedule_one function. The
2146 function runs scheduler once and returns.
2148 * Fixed the scheduler after cras messed it up. The timeout
2149 handling works now as it's supposed to work.
2151 * Added into lib/silccore/ silcnotify.h to include notify
2152 message types support. Changed silc_server_send_notify*
2153 functions, in server.[ch], to support those new notify types.
2154 Added the support for the notify types into client library,
2155 as well. Added new notify client operation into ops.h in
2158 * Changed silc_server_packet_send_to_channel to send normal
2159 packets instead of just channel message packets. The function
2160 is now used to send the notify packets to channels. It is not
2161 used to send channel message packets anymore, as server never
2164 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
2165 va_arg()s as it seems to require it nowadays. I guess, if SILC
2166 is compiled with older va_arg() the new code should work anyway.
2168 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2170 * Splitted core library. Core library (lib/silccore) includes
2171 now only SILC protocol specific core (and common) components.
2172 Created new utility library (lib/silcutil) that includes more
2173 generic purpose stuff. The stuff for util library was taken
2174 from the old core library. This was minor and easy split.
2176 * Created SILC Client Library (lib/silcclient) that includes
2177 implementation of the SILC client without user interface. This
2178 was major move from silc/ directory. The code has been changed
2179 so that it is transparent towards the user interface. The
2180 silc/ directory includes now the same user interface as before
2181 and it uses the new client library. Read lib/silcclient/README.
2182 Basicly, the client library performs everything else related
2183 to SILC except user interface handling. Also, configuration
2184 files are considered to be part of user interface and library
2185 does not handle them.
2187 This change also changed a lot of structures, function naming etc.
2188 Most important change was that SilcClientWindow object was
2189 renamed to SilcClientConnection in the client library. Created
2190 also new file lib/silcclient/ops.h. Also added new files
2191 silc/local_command.[ch] and silc/client_ops.[ch].
2193 All these changes were made to make it easier for user interface
2194 designers to create what ever user interface for the SILC client
2197 It is also expected that the server will be moved to lib
2198 directory as well and SILC Server Library will be created;
2199 sometimes in the future.
2201 * Removed Local commands from lib/silccore/silccommand.h as
2202 they are application specific and new client library does not
2203 handle any of those anymore.
2205 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2206 old client implementation in silc/.
2208 * Added support for callback functions in SILC_LOG_* macros.
2209 Application can now set its own callbacks that will be called
2210 instead of using the default functions that will always print
2211 the debug messages to stderr (or stdout). Also, debugging can
2212 now be disabled by setting silc_debug to FALSE and re-enabled by
2213 setting it to TRUE. Note, that logging will still work even
2214 if debugging is disabled.
2216 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2217 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2218 silc_log_reset_debug_callbacks.
2220 * To enable debugging in silc client one must give now -d
2221 option on command line.
2223 * Changed silc_schedule_init to automatically allocate task queues
2224 if they are not allocated before calling it.
2226 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2228 * Added GMP 3.1 into math library.
2230 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2232 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2233 a channel in SILC network. The packet is used by servers and
2234 routers to notify other routers that user has left a channel.
2235 This little feature was missing until now. Added the feature
2236 to protocol specification as well.
2238 Added functions: silc_server_send_remove_channel_user and
2239 silc_server_remove_channel_user into server.[ch].
2241 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2242 lib/silccore/silcpacket.h. However, they are not implemented
2245 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2247 * Fixed joining to a channel and sending channel messages
2248 between server and router. The channel message sending should
2249 now work inside a cell.
2251 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2253 * Fixed the private message sending between server and router.
2254 The private message sending should now work inside a cell.
2256 * Added silc_server_replace_id into server.[ch] to replace
2257 existing ID in the SILC network.
2259 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2260 and silc_idlist_replace_server_id into idlist.[ch] in server.
2262 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2264 * Fixed the server to server connections. Server can again now
2265 connect to router. Router to router connections probably does
2268 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2270 * Added dynamic protocol registering support. Now protocols can
2271 registered and unregistered on the fly. Patch by cras.
2273 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2275 * Added lib/contrib directory to hold routines that some platforms
2276 don't have but are needed by SILC.
2278 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2279 into lin/contrib to provide getopt() and getopt_long() for
2280 those who don't have it.
2282 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2284 * Added AWAY command to client. When away message is set and
2285 client receives a private message packet the client automatically
2286 replies to the sender with the away message.
2288 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2289 bug seemed to be the cause of recent problems when compiling
2292 * Added version detection support to SKE protocol specification
2293 and added the new changes to the SKE implementation as well.
2294 There were other minor changes in the SKE protocol as well.
2296 Many changes in lib/silcske/silcske.[ch] and in
2297 lib/silcske/payload.[ch].
2299 * Added ^U functionality, clear input line. Patch from cras.
2301 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2303 * Mainly small bugfixes on core library. Fixed some debugging
2304 logging and buffer overflow in silclog.c.
2306 * Updated config.sub and config.guess on the distribution tree.
2308 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2310 * Added command lagging support in server. Client may execute
2311 commands now only once in two seconds.
2313 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2315 * Optimized packet reception. MAC computation and checking is now
2316 also more optimized. A lot previously duplicated code is now
2317 used as generic by both client and server.
2319 * Fixed key pair generation in clientutil.c
2321 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2323 * Added into lib/silccore/silcbufutil.[ch] new function;
2324 silc_buffer_realloc.
2326 * Moved generic packet sending/encryption functions to
2327 lib/silccore/silcpacket.[ch] from client and server. Some
2328 rewriting of the functions.
2330 * Moved all generic packet reception/decryption functions to
2331 lib/silccore/silcpacket.[ch] from client and server. The
2332 packet processing is now much cleaner in both client and server.
2333 These were major changes in both client and server.
2335 * Created many common functions in server to do packet sending.
2336 Previously code were duplicated a lot, this has been removed
2339 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * Rewrote major parts of the ID cache system. Don't know
2342 whether it is better now or not but at least the API is more
2345 * Major rewrite on ID cache stuff on client because of the ID
2346 cache API changes. Added idlist.c to client.
2348 * Also major rewrite on ID cache stuff on server as well.
2349 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2350 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2351 in hand, instead they are all put into the ID cache system now.
2352 All server_idlist_* routines uses ID cache now instead of
2353 traversing its own lists (those lists does not exist anymore).
2354 SilcIDList though still exists. Also, SilcXXXEntry's are
2357 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2359 * Finally made the SKE implementation compliant to the protocol
2360 specification. All mp integers are now binary encoded as
2361 opposed being HEX encoded.
2363 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2366 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2367 functions: silc_[encode/decode]_pem. Also added function
2368 silc_encode_pem_file to PEM encode with newlines ('\n') for
2371 * SILC public keys are now encoded either PEM or binary. Same
2372 option is for private keys as well. By default private keys
2373 are binary encoded and public keys PEM encoded. Silly HEX
2374 encoding were removed.
2376 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2377 function to create fingerprints.
2379 * Fixed a bug in SHA1; does not change the original data anymore.
2381 * Partly implemented INFO command on client and server side.
2382 Fixed CLEAR command. Changes to SERVER command; show current
2383 server(s) when giving command without arguments. Added
2384 VERSION command to client.
2386 * Added check to server that unregistered connections cannot
2387 execute commands (unless it is specificly allowed).
2389 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2391 * Fixed screen refresh.
2393 * Fixed channel joining bug from client. On some circumstances
2394 client tried to join to a channel it had already joined.
2396 * Added public key verification process into client's protocol.c.
2397 The client now verifies the public key from user and saves
2398 it into ~./silc/serverkeys/ directory.
2400 Added into: clientutil.[ch]: silc_client_verify_server_key.
2402 * Changed SKE protocol's silc_ske_initiator_finish function
2403 to accept callback function that verifies the received public
2404 key. Removed old silc_ske_verify_public_key function.
2406 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2408 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2409 silc_pkcs_private_key[_data]_set.
2411 * Made the password and public authentication more cleaner in
2412 server's protocol.c.
2414 * Removed historic and obsolete protocol `channel_auth' from
2415 both client and server.
2417 * Removed wrong way of sending command status messages from
2418 server to client in server's command.c. The old way violated
2419 protocol specification.
2421 Changes to silccore/silccommand.[ch]: removed
2422 silc_command_encode_status_payload -> not needed anymore,
2423 changed silc_command_encode_payload_va to accept extra
2424 argument on variable argument list. The argument type must
2425 now be provided to the function. Also, added new function:
2426 silc_command_encode_reply_payload_va which is same as
2427 normal command_encode_payload_va except command status type
2428 is provided as extra argument.
2430 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2432 * Added ~./silc directory handling. The directory includes the
2433 public and private keys for the client.
2435 Added silc_client_check_silc_dir, silc_client_create_identifier
2436 and silc_client_load_keys.
2438 * Implemented SILC protocol compliant public key. Added public
2439 and private key saving to and loading from files.
2441 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2442 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2443 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2444 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2445 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2447 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2448 silc_pkcs_load_[public/private]_key.
2450 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2452 * Added silc_server_get_route (route.[ch]) to get connection
2453 data for the fastest route for given ID.
2455 * Implemented INVITE command on client and server. The command
2456 were re-defined in the SILC Protocol Specification and the
2457 implementation now complies with the specification.
2459 * Implemented PING command on client and server.
2461 * Implemented NAMES command on client and server. The server side
2462 supports currently only normal server not router server yet.
2463 Some changes to NAMES definition in SILC protocol specification.
2465 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2467 * Implemented LEAVE command on client and server.
2469 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2470 again. This change was made to the protocol as well. Server
2471 should not violate the protocol specification anymore.
2473 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2475 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2476 was tested. SOCKS4 was not but should work anyway.
