1 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
4 just surfaced after chaning the JOIN procedure.
6 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * Added silc_client_get_clients_by_list to get client entries
9 from Client ID list, that is returned for example by JOIN
10 and USERS command replies. The application should use this
11 function for example when JOIN command reply is received to
12 resolve the clients already on the channel (library does not
13 do that anymore as USERS command reply is not used in the JOIN
14 procedure anymore). Affected files lib/silcclient/silcapi.h and
15 lib/silcclient/idlist.c.
17 * JOIN command reply and USERS command reply returns now SilcBuffer
18 pointers instead of unsigned char pointers when returning
19 the client list and mode list.
21 * Added <Client ID> argument to the JOIN command reply, mainly
22 for the server to identify for which client the command was
23 originally sent. Updated protocol specs accordingly.
25 * Added SilcDlist private_key pointer to the SilcChannelEntry
26 in the client to support the channel private keys. Affected
27 file is lib/silcclient/idlist.h.
29 * Added SilcChannelPrivateKey argument to the function
30 silc_client_send_channel_message so that application can choose
31 to use specific private ke if it wants to. If it is not provided,
32 the normal channel key is used, unless private keys are set.
33 In this case the first (key that was added first) is used
34 as the encryption key.
36 * Implemented the support for channel private key handling.
37 Implemented the following functions:
39 silc_client_add_channel_private_key,
40 silc_client_del_channel_private_keys,
41 silc_client_del_channel_private_key,
42 silc_client_list_channel_private_keys and
43 silc_client_free_channel_private_keys
45 Affected file lib/silcclient/client_channel.c.
47 * Added the support for the private keys in the channel message
48 sending and encryption and in the message reception and
49 decryption. Affected funtions are
50 silc_client_send_channel_message and silc_client_channel_message.
52 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
54 * Added SKE's key verify callback to the client library's
55 KE protocol context. Affected files lib/silcclient/protocol.[ch].
57 * Removed the statement that server (or router) must send USERS
58 command reply when joining to the channel so that the client
59 knows who are on the channel. Instead, the client list and
60 client's mode list is now sent in the JOIN command reply to the
61 client who joined channel. This is better solution.
63 * Added function silc_server_get_users_on_channel and function
64 silc_server_save_users_on_channel to the silcd/server.[ch].
66 * Removed function silc_server_command_send_users from the
69 * Do not show topic on the client library anymore. The topic is
70 sent in the command reply notify to the application and the
71 application must show the topic now.
73 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
75 * Added client searching by nickname hash into the IDENTIFY and
76 WHOIS commands in the server as they were clearly missing from
77 them. Affected file is silcd/command.c.
79 * Fixed a bug in private message receiving in the client library.
80 The remote ID was freed and it wasn't supposed, now it is
83 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
85 * Minor fix to the channel payload; allocate the data area, as it
86 needs to be of specific length.
88 * If the key agreement port is zero then the operating
89 system will define the bound port. Affected files are
90 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
92 * Added new function silc_channel_payload_decrypt into the file
93 lib/silccore/silcchannel.[ch].
95 * Moved the channel message etc, check from silc_packet_decrypt
96 to applications. The library calls now a generic
97 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
98 when the packet is either normal or special. This was done to
99 allow more wide range of checking that was not allowed when
100 the code was in library. Now applications can do virtually any
101 checks to the packet and return to the library the decision how
102 the packet should be processed. Affected files are
103 lib/silccore/silcpacket.[ch].
105 Added silc_server_packet_decrypt_check to the server and
106 silc_client_packet_decrypt_check to the client library.
108 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
109 to send with specified source and destination information.
111 * Channel message delivery between routers was broken after the
112 channel key distribution was fixed earlier. The channel key
113 was used be to distributed to other routers as well which is not
114 allowed by the protocol. Now this is fixed and channel keys
115 really are cell specific and the channel message delivery between
116 routers comply with the protocol specification.
118 * Fixed various commands in server to check also the global list
119 for the channel entry and not just the local list. The affected
120 file silcd/command.c.
122 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
124 * Added assert()s to buffer formatting and unformatting routines
125 to assert (if --enable-debug) when error occurs. Affected
126 file: lib/silcutil/silcbuffmt.c.
128 * Changed to auto-reconnect to check whether the remote host is
129 router and register the re-connect timeout if it is. It used
130 to check that whether we are normal server, but router must do
131 auto-reconnect with another router as well. Affected file
134 * Removed the [<key len>] option from CMODE command as the cipher
135 name decides the key length, nowadays. See the defined ciphers
136 from the protocol specification.
138 * Added [<hmac>] option to the CMODE command to define the HMAC
139 for the channel. Added SILC_CMODE_HMAC channel mode.
141 * Added [<hmac>] option for the JOIN command so that user can
142 select which HMAC is used to compute the MACs of the channel
145 * Added Hmac field to the Channel Message Payload. The integrity
146 of plaintext channel messages are now protected by computing
147 MAC of the message and attaching the MAC to the payload. The
148 MAC is encrypted. Now, it is clear that this causes some
149 overhead to the size of the packet but rationale for this is that
150 now the receiver can verify whether the channel message decrypted
151 correctly and also when private keys are set for the channel the
152 receiver can decrypt the packet with several keys and check from
153 the MAC which key decrypted the message correctly.
155 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
156 lib/silccrypt/silccipher.[ch].
158 * Added silc_hash_len to return the digest length into the
159 lib/silcrypt/silchash.[ch].
161 * Rewrote parts of Silc Channel Payload interface in the
162 lib/silccore/silcchannel.[ch]. The encode function now also
163 encrypts the packet and parse function decrypts it.
165 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
167 * Fixed a minor formatting bug in the SKE's key material processing.
168 It actually might have processed the keys wrong way resulting
171 * Redefined the mandatory HMAC algorithms and added new algorithms.
172 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
173 and hmac-md5 truncated to 96 bits. The mandatory is now
174 hmac-sha1-96. Rest are optional (including the one that used
175 to be mandatory). Rationale for this is that the truncated HMAC
176 length is sufficient from security point of view and can actually
177 make the attack against the HMAC harder. Also, the truncated
178 HMAC causes less overhead to the packets. See the RFC2104 for
181 * Added new [hmac] configuration section. The SKE used to use
182 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
183 is of course wrong. The official names that must be proposed in
184 the SKE are the ones defined in the protocol specification
185 (hmac-sha1-96 for example). The user can configure any hmac
186 using any hash function configured in the [hash] section. At
187 least, the mandatory must be configured.
189 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
191 * Added HMAC list to the SKE proposal list. It has now both
192 hash algorithm list and HMAC list. This makes the protocol
193 incompatible with previous versions. The SKE now seems to work
194 the way it is supposed to work, for the first time actually.
196 * Defined plain Hash algorithms to the protocol specification.
199 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
201 * Implemented support for key agreement packets into the server.
202 Added functions silc_server_key_agreement and
203 silc_server_send_key_agreement. Other than these functions,
204 server has nothing to do with this packet.
206 * Added support for private message key packets into the server.
207 Added functions silc_server_private_message_key and
208 silc_server_send_private_message_key.
212 * Changed the silc_[client|server]_protocol_ke_set_keys to be
213 called in the protocol's final callback instead in the END
214 protocol state. This makes a little more sense and in the same
215 time in client we can use the same protocol routines for normal
216 key exchange and to key agreement packet handling as well.
218 * Added to both client's and server's KE protocol context the
219 SilcSKEKeyMaterial pointer to save the key material. We will
220 bring the key material to the protocol's final callback by doing
221 this. The final callback must free the key material.
223 * Added SKE's packet_send callback into client's KE protocol
224 context so that the caller can choose what packet sending function
225 is used. This way we can use different packet sending when
226 doing normal SKE when doing key agreement packet handling (in
227 the key agreement packet handling we do not want to encrypt
230 * Implemented the responder side of the key agreement routines
231 in the client. The client can now bind to specified port and
232 accept incoming key negotiation. The key material is passed
233 to the application after the protocol is over.
235 * Implemented the processing of incoming Key Agreement packet
236 in the client. Added function silc_client_key_agreement to
239 * Implemented the intiator side of the key agreement routines
240 in the client. The client can now initiate key agreement with
241 another remote client. The key material is passed to the
242 application after the protocol is over.
244 * Created client_keyagr.c to include all the key agreement
247 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
248 SILC_TASK_CALLBACK except that it is not static.
250 * Created client_notify.c and moved the Notify packet handling
251 from the client.[ch] into that file.
253 * Created client_prvmsg.c and moved all private message and
254 private message key routines from the client.[ch] into that file.
256 * Create client_channel.c and moved all channel message and
257 channel private key routines from the client.[ch] into that file.
259 * Changed silc_client_get_client_by_id_resolve to resolve with
260 WHOIS command instead of IDENTIFY command, in the file
261 lib/silclient/idlist.c.
263 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
265 * Implemented the SKE's responder side to the Client library.
267 * When FAILURE is received to the protocol do not trust it
268 blindly. Register a timeout to wait whether the remote closes
269 the connection as it should do it, only after that process the
270 actual failure. This was changed to both client and server.
272 * Added client_internal.h to include some of the structures
273 there instead of client.h in lib/silcclient/.
275 * Added function silc_task_unregister_by_callback to unregister
276 timeouts by the callback function.
278 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
280 * Some "Incomplete WHOIS info" errors has been appearing on the
281 log files. Took away the entry->userinfo check from WHOIS
282 reply sending. The entry->userinfo is now " " if client did not
283 provide one. I thought this was fixed earlier but something
284 is wrong still. Let's see if the error still appears.
286 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
288 * Fixed a minor bug in the login when the channel key is
289 re-generated in the server. It used to generate the key in
290 wrong order and thus caused problems in the channel traffic.
292 * Fixed a minor bug in channel key distsribution after
293 KICK command. The key was not sent to the router even though
296 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
298 * Added silc_ske_process_key_material_data as generic routine
299 to process any key material as the SILC protocol dictates. The
300 function is used by the actual SKE library but can be used by
301 applications as well. This relates to the private message keys
302 and the channel private keys since they must be processed the
303 same way the normal SILC session keys. The protocol dictates
304 this. Affected files: lib/silcske/silcske.[ch].
306 Added also silc_ske_free_key_material to free the
307 SilcSKEKeyMaterial structure.
309 * Defined silc_cipher_set_key function to set the key for
310 cipher without using the object's method function. The affected
311 files: lib/silccrypt/silccipher.[ch].
313 * Implemented silc silc_client_add_private_message_key,
314 silc_client_add_private_message_key_ske,
315 silc_client_del_private_message_key,
316 silc_client_list_private_message_keys and
317 silc_client_free_private_message_keys functions in the
320 Added functions silc_client_send_private_message_key to send
321 the Private Message Key payload and silc_client_private_message_key
322 to handle incoming Private Message Key payload.
324 * Added Cipher field to the Private Message Key payload to set
325 the cipher to be used. If ignored, the default cipher defined
326 in the SILC protocol (aes-256-cbc) is used.
328 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
330 * Removed lib/silcclient/ops.h file.
332 Redefined parts of the SILC Client Library API. Created new
333 file silcapi.h that deprecates the ops.h file and defines the
334 published Client Library API. Defined also private message key
335 API and channel private key API into the file.
337 This is the file that the application must include from the
338 SILC Client Library. Other files need not be included by
339 the application anymore.
341 * Added new key_agreement client operation callback and also
342 defined the Key Agreement library API for the application.
344 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
346 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
347 is used by clients to request key negotiation between another
348 client in the SILC network. If the negotiation is started it
349 is performed using the SKE protocol. The result of the
350 negotiation, the secret key material, can be used for example
351 as private message key.
353 Implemented the Key Agreement payload into the files
354 lib/silccore/silauth.[ch].
356 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
358 * Redefined ciphers for the SILC protocol. Added some new ciphers
359 and defined the key lengths for the algorithms. Changed the
360 code accordingly. The default key length is now 256 bits.
362 * Fixed SKE key distribution function silc_ske_process_key_material
363 when the key length is more than 128 bits. The default key
364 length in SILC is now 256 bits.
366 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
367 to indicate unsupported algorithm.
369 * Renamed rijndael.c to aes.c and all functions as well.
371 * Fixed a long standing channel key setting bug in client library.
372 Weird that it has never surfaced before.
374 * Fixed bug in channel deletion. If the entire channel is removed
375 then it must also delete the references of the channel entry
376 from the client's channel list as the client's channel entry and
377 the channel's client entry share same memory.
379 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
381 * Implemented CONNECT and SHUTDOWN commands in the client.
383 * Implemented CLOSE command to the client.
385 * Added the function silc_idlist_find_server_by_name into the
386 files silcd/idlist.[ch].
388 Added the function silc_idlist_find_server_by_conn into the
389 files silcd/idlist.[ch].
391 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
393 * DIE command was renamed to SHUTDOWN. Updated the both code
396 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
397 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
399 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
402 * Added function silc_server_create_connection function to create
403 connection to remote router. My server implementation actually
404 does not allow router to connect to normal server (it expects
405 that normal server always initiates the connection to the router)
406 so the CONNECT command is only good for connecting to another
409 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
411 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
412 or some other client was kicked from the channel.
414 Implemented the handling of the notify type to both client
417 Implemented silc_server_send_notify_kicked to send the KICKED
418 notify. It is used to send it to the server's primary router.
420 * Implemented the KICK command into server and client.
422 * Added `query' argument to the silc_idlist_get_client function
423 to indicate whether to query the client from server or not if
426 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
427 to indicate that the client is not channel founder.
431 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
433 * Removed the rng context from SilcPacketContext structure and
434 changed that the packet routine uses the Global RNG API.
436 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
438 * Added support for quit message that client can "leave" on the
439 channel when it quits the SILC. It is ditributed inside the
440 SILC_NOTIFY_TYPE_SIGNOFF notify type.
442 Added silc_server_free_client_data that will take the
443 signoff message as argument.
445 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
447 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
449 * Updated parts of the protocol specification to keep it up
452 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
454 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
455 payloads in one packet.
457 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
458 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
459 use now the new List flag.
461 * Also deprecated the following packet types: REPLACE_ID,
462 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
464 * Added list support for Notify packet in server.
466 * Added silc_server_send_notify_channel_change to send the
467 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
468 the silc_server_send_replace_id.
470 * Added silc_server_send_notify_nick_change to send the
471 NICK_CHANGE notify type. Deprecates the function
472 silc_server_send_replace_id.
474 * Added silc_server_send_notify_join to send the JOIN notify type.
475 Deprecates the function silc_server_send_new_channel_user.
477 * Added silc_server_send_notify_leave to send LEAVE notify type.
478 Deprecates the function silc_server_send_remove_channel_user.
480 * Added silc_server_send_notify_cmode and
481 silc_server_send_notify_cumode to send CMODE and CUMODE notify
482 types. Deprecates the silc_server_send_set_mode function.
484 * Added SERVER_SIGNOFF notify type to indicate that server has
485 quit. This means that all clients on the channel from that
486 server will drop. This can be also used when netsplit happens.
488 Deprecated REMOVE_ID packet type since it is not needed anymore
491 Added silc_server_send_notify_server_signoff to send the
492 SERVER_SIGNOFF notify type. Deprecates the function
493 silc_server_send_remove_id.
495 Added also silc_server_send_notify_signoff to send the
498 * Employed the PKCS #1. It is the mandatory way to do RSA in the
499 SILC protocol from this day on. Changed the protocol
500 specification as well.
502 * Added silc_server_send_notify_topic_set to send TOPIC_SET
503 notify type. It is used between routers to notify about
504 topic changes on a channel.
506 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
509 * Partly updated the protocol specification to comply with the
510 changes now made. It is still though a bit outdated.
512 * The JOIN notify type now takes one extra argument <Channel ID>.
513 The packet used to be destined to the channel but now the
514 JOIN type may be sent as list thus it is impossible to
515 destine it to any specific channel. By adding this argument
516 it is again possible.
518 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
520 * Added CREDITS file. The CHANGES and CREDITS file will appear
521 in the distribution as well.
523 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
525 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
526 types in the server's silcd/packet_receive.c.
528 * Implemented CMODE and CUMODE to work in router environment.
530 * Fixed minor encoding and decoding buglet from the
531 lib/silccore/silcmode.c.
533 * Fixed buffer overflow from lib/silcclient/command.c in USERS
536 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
538 * Changed all SilcConfigServer* and silc_config_server* to
539 SilcServerConfig* and silc_server_config*, respectively.
542 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
544 * Associated the ID (client or server ID) to the Authentication
545 Payload to avoid any possibility of forging. Updated the
546 protocol specification and the code accordingly.
548 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
550 * The RSA key length is now save to the RsaKey context in the
551 key generation process in lib/silccrypt/rsa.c. The key length
552 is now used to figure out the maximum size of the block allowed
553 to be encrypted/signed.
555 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
556 is equivalent to the silc_mp_mp2bin but does not allocate any
559 * Changed silc_mp_mp2bin API to take length argument. If it is
560 non-zero then the buffer is allocated that large. If zero, then
561 the size is approximated using silc_mp_sizeinbase, which however
564 * Created Global RNG API which is global RNG that application can
565 initialize. After initializing, any routine anywhere in the
566 code (including library) can use RNG without allocating a new
567 RNG object. This was done to allow this sort of use of the
568 RNG in code that has no chance to allocate RNG object. All
569 applications currently allocate this and many routines in the
570 library use this. Affected file lib/silccrypt/silcrng.[ch].
572 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
573 it to use the Global RNG API.
575 * Defined Authentication Payload into protocol specification that
576 is used during SILC session to authenticate entities. It is
577 used for example by client to authenticate itself to the server
578 to obtain server operator privileges.
580 Implemented this payload into the lib/silccore/silcauth.[ch].
581 Implemented also routines for public key based authentication
582 as the new protocol specification dictates.
584 Moved definitions of different authentication methods from
585 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
587 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
588 silc_pkcs_verify and silc_pkcs_sign_with_hash and
589 silc_pkcs_verify_with_hash functions into the file
590 lib/silccrypt/silcpkcs.[ch].
592 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
594 * The client entry's userinfo pointer must be always valid.
595 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
596 will fail since it requires the userinfo. Now, the userinfo
597 is allocated as "" if actual userinfo does not exist. Actually,
598 it must exist and it is totally Ok to drop client connections
599 that does not announce the userinfo. However, we will make
600 this workaround for now.
602 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
603 to return the remote port by socket.
605 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
607 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
608 SILC_SERVER_PENDING_EXEC and added an new macro
609 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
610 data or when error occurs while processing the pending command.
612 Added new argument `destructor' into silc_server_command_pending
613 and to the SilcServerCommandPending object. This destructor is
614 now called after calling the pending callback or if error occurs
615 immediately. If error occurs the actual pending callback won't
616 be called at all - only the destructor. The destructor may be
617 NULL if destructor is not needed.
619 All this applies for client library code as well. Similar
620 changes were made there as well for the pending commands.
622 In the client, the application must now allocate the
623 SilcClientCommandContext with the silc_client_command_alloc
626 * Added reference counter to the SilcServerCommandContext. Added
627 function silc_server_command_alloc and silc_server_command_dup
630 Same type of functions added to the client library for the same
633 * Removed the cmd_ident from IDListData away since it is now
634 global for all connections. It is the command identifier used
635 in command sending and with pending commands. The affected file
638 * Added reference counter to the SilcSocketConnection objecet to
639 indicate the usage count of the object. The object won't be
640 freed untill the reference counter hits zero. Currently only
641 server uses this, and client ignores it. The client must be
642 set to use this too later. The affected files are
643 lib/silccore/silcsockconn.[ch]. Added also the function
644 silc_socket_dup to increase the reference counter.
646 This was mainly added because it is possible that the socket
647 is removed underneath of pending command or other async
648 operation. Now it won't be free'd and proper DISCONNECTING
649 flags, etc. can be set to avoid sending data to connection that
650 is not valid anymore.
652 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
653 the connection. After that it sets SILC_SET_DISCONNECTED.
654 It is, however, possible that the socket data is not still freed.
655 The silc_server_packet_process now checks that data is not
656 read or written to connection that is DISCONNECTED. The socket
657 get's freed when the reference counter hits zero.
659 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
661 * Changed the client operation API: channel_message operation's
662 `sender' is now the client entry of the sender, not the nickname
663 and the `channel' is the channel entry, not the channel name.
665 In the private_message operation the `sender' is now also the
666 client entry of the sender not the nickname.
668 Affected file is lib/silcclient/ops.h and all applications
669 using the client operations.
671 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
673 * Moved the calling of ops->connect() from connect_to_server_final
674 into receive_new_id functin since that is the point when the
675 client is actually allowed to send traffic to network. The
676 affected file is lib/silcclient/client.c.
678 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
680 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
681 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
682 (if needs broadcasting) instead of broadcasting the packets one
683 by one which would make a burst in the network traffic.
685 * Added `broadcast' argument to the functions in silcd/server.[ch]
686 silc_server_create_new_channel[_with_id] to indicate whether
687 to send New Channel packet to primary router.
689 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
691 * Added new function into the silcd/server.[ch] files:
692 silc_server_create_new_channel_with_id to create new channel with
693 already existing Channel ID.
695 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
696 lib/silccore/silcpacket.h. This packet is used t send list of
697 Set Mode payloads inside one packet. Server uses this to set
698 the modes for the channels and clients on those channels, that it
699 announced to the router when it connected to it. The protocol
700 specification has been updated accordingly.
702 * The silc_server_new_channel did not handle the packet coming
703 from normal server as it normally does not send that. However,
704 when it announces its channels it does send it. Implemented
705 the support for that.
707 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
708 into the file lib/silccore/id.h.
710 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
712 * Fixed memory leaks in the functions silc_idlist_del_client,
713 silc_idlist_del_channel and silc_idlist_del_server in the file
714 silcd/idlist.c. All of those leaked like a sieve.
716 * Fixed some small memory leaks in the client's function
717 silc_client_notify_by_server.
719 * Added functions into silcd/server.c: silc_server_announce_clients,
720 silc_server_announce_channels and silc_server_announce_server.
721 These functions are used by normal and router server to announce
722 to its primary router about clients, channels and servers (when
723 router) that we own. This is done after we've connected to the
726 These functions effectively implements the following packet types:
727 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
728 and SILC_PACKET_NEW_ID_LIST.
730 * Added new functions into the silcd/packet_receive.[ch]:
731 silc_server_new_id_list, silc_server_new_channel_list and
732 silc_server_new_channel_user_list to handle the incoming
733 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
735 * Added support of changing Channel ID in the function
736 silc_server_replace_id. If the server that announces a channel
737 to the router already exists in the router (with same name but
738 with different Channel ID), router is responsible to send
739 Replace ID packet to the server and force the server to change
740 the Channel ID to the one router has.
742 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
743 client that the Channel ID has been changed by the router. The
744 normal server sends this to the client. Client must start using
745 the new Channel ID as the channel's ID.
747 Implemented handling of this new type into lib/silcclient/client.c
748 into the function silc_client_notify_by_server.
750 * Added new function silc_idlist_replace_channel_id into the files
751 silcd/idlist.[ch] to replace the Channel ID.
753 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
755 * Call silc_server_command_identify_check always when processing
756 the IDENTIFY command in silcd/command.c
758 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
760 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
761 send keepalive packets. The packet can be sent by clients,
764 Added function silc_socket_set_heartbeat into the file
765 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
766 If not set, the heartbeat is not performed. The actual
767 heartbeat is implemented in the low level socket connection
768 library. However, application is responsible of actually
771 Added silc_server_send_heartbeat to send the actual heartbeat
772 packet into silcd/packet_send.[ch]. Server now performs
773 keepalive with all connections.
775 * Added silc_task_get_first function into lib/silcutil/silctask.c
776 to return the timeout task with shortest timeout. There was a bug
777 in task unregistration that caused problems. TODO has been
778 updated to include that task system must be rewritten.
780 * The client library will now resolve the client information when
781 receiving JOIN notify from server for client that we know but
782 have incomplete information.
784 * Rewrote parts of silc_server_remove_from_channels and
785 silc_server_remove_from_one_channel as they did not remove the
786 channel in some circumstances even though they should've.
788 * Encryption problem encountered in server:
790 The LEAVE command used to send the Channel Key packet to the
791 router immediately after generating it. However, the code
792 had earlier sent Remove Channel user packet but not immediately,
793 ie. it was put to queue. The order of packets in the router
794 was that Channel Key packet was first and Remove Channel User
795 packet was second, even though they were encrypted in the
796 reverse order. For this reason, MAC check failed. Now, this
797 is fixed by not sending the Channel Key packet immediately but
798 putting it to queue. However, this is more fundamental problem:
799 packets that are in queue should actually not be encrypted
800 because packets that are sent immediately gets encrypted
801 actually with wrong IV (and thus MAC check fails). So, packets
802 that are in queue should be encrypted when they are sent to
803 the wire and not when they put to the queue.
805 However, the problem is that the current system has not been
806 designed to work that way. Instead, the packet is encrypted
807 as soon as possible and left to the queue. The queue is then
808 just purged into wire. There won't be any fixes for this
809 any time soon. So, the current semantic for packet sending
812 o If you send packet to remote host and do not force the send
813 (the packet will be in queue) then all subsequent packets to the
814 same remote host must also be put to the queue. Only after the
815 queue has been purged is it safe again to force the packet
818 o If you send all packets immediately then it safe to send
819 any of subsequent packets through the queue, however, after
820 the first packet is put to queue then any subsequent packets
821 must also be put to the queue.
823 Follow these rules and everything works fine.
825 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
827 * Added new function silc_server_remove_clients_by_server to
828 remove all client entries from ID list when the server connection
829 is lost. In this case it is also important to invalidate all
830 client entires as they hold the invalid server entry. This
831 fixes fatal bug when server has lost connection and will reconnect
834 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
836 * Made some sanity checks to silc_server_daemonise like to check
837 whether the requested user and group actually exists.
839 * Added sanity check to SKE's silc_ske_responder_finish to check
840 that the public and private key actually is valid.
842 * Invalidate the client's nickname when receiving Replace ID
843 packet and the Client ID is being replaced. This means that the
844 server will query the nickname if someone needs it (client)
847 * Sort the ID Cache in client library when the ID Cache data
848 has changed (needs sorting).
850 * Do not allow for SILC client to create several connections to
851 several servers. The client does not support windows right now
852 and generating multiple connections causes weird behaviour.
854 Irssi-silc client does support windows and can handle several
855 connections without problems, see: www.irssi.org and SILC plugin.
857 * Fixed some places where client was added to the IDList. The
858 rule of thumb is following (in order to get everything right):
859 If the client is directly connected local client then the
860 `connection' argument must be set and `router' argument must be
861 NULL to silc_idlist_add_client function. If the client is not
862 directly connected client then the `router' argument must
863 bet set and the `connection' argument must be NULL to the
864 silc_idlist_add_client function.
866 * The funtion silc_server_packet_send_local_channel actually did
867 not check whether the client was locally connected or not. It
868 does that now. Fixed a bug related to LEAVE command.
870 * Fixed Remove Channel User payload parsing bug in server's
871 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
873 * The server's silc_server_save_channel_key now checks also the
874 global ID list for the channel as it might not be in the local
875 list. Fixed a bug related to LEAVE command.
877 * Is this the end of the [<unknown>] buglet that has been lurking
878 around for a long time? A little for loop fix in server's
879 silc_server_command_whois_parse that is used by both IDENTIFY
880 and WHOIS command. At least, this was a clear bug and a cause
881 of one type of [<unknown>] buglet.
883 * WHOIS and IDENTIFY commands call the function
884 silc_server_command_[whois/identify]_check function even if
885 we are not router server.
887 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
889 * Added --with-gmp configuration option. If set the GMP
890 is always compiled in the SILC source tree. If not set then
891 it is checked whether the system has the GMP3 installed. If
892 it has then the GMP won't be compiled (the system's headers
893 and library is used), if it doesn't have it then the GMP is
894 compiled in the SILC source tree.
896 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Changed RSA private exponent generation to what PKCS #1
899 suggests. We try to find the smallest possible d by doing
900 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
901 not security fix but optimization.
903 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
905 * Added new config entry [Identity] to fork the server and run
906 it as specific user and group. A patch from Bostik.
908 * Imported Dotconf configuration library into lib/dotconf.
909 This will be used to create the SILC configuration files later.
910 It will appear in the distsribution after this commit.
912 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * A big code auditing weekend happening. Auditing code for
915 obvious mistakes, bugs and errors. Also, removing any code
918 Removed files for being obsolete:
920 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
921 inline in the file lib/silcutil/silcbuffer.h)
923 o lib/silcutil/silcbufutil.c (the header has inline versions)
925 Changed code to fix possible error conditions:
927 o The buffer formatting routines now check that the destination
928 buffer really has enough space to add the data. This applies for
929 both buffer formatting and unformatting
930 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
931 unformatting was changed to accomodate following rules:
932 XXX_*STRING_ALLOC will allocate space for the data into the pointer
933 sent to the function while XXX_*STRING will not allocate or copy
934 the data into the buffer. Instead it sets the pointer from the
935 buffer into the pointer sent as argument (XXX_*STRING used to
936 require that the pointer must be allocated already). This change
937 makes this whole thing a bit more consistent and more optimized
938 (note that the data returned in the unformatting with XXX_*STRING
939 must not be freed now). The routines return now -1 on error.
941 o Tried to find all code that use buffer_format and buffer_unformat
942 and added return value checking to prevent formatting and
943 especially unformatting errors and possible subsequent fatal
946 o Changed ske->x and ske->KEY to mallocated pointers in
947 lib/silcske/silcske.h. Fixed possible data and memory leak.
949 o Added return value checking to all *_parse* functions. Fixed
950 many memory leaks as well.
952 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
953 so that buffer overflows would not happen. All code now also
954 checks the return value as it can fail.
956 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
958 * Added reconnection support to server if the normal server looses
959 its connection to the router (for example if router is rebooted).
960 The server performs normal reconnection strategy implemented
961 to the server. Affected file silcd/server.c.
963 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
965 * Added new packet type SILC_PACKET_SET_MODE that is used to
966 distribute the information about changed modes (for clients,
967 channels and clients channel modes) to all routers in the
968 network. Updated the protocol specification accordingly.
970 Added functions into silcd/packet_send.c and
971 silcd/packet_receive.c: silc_server_send_set_mode,
972 silc_server_set_mode.
974 Added new files silcmode.[ch] into lib/silccore that implements
975 the encoding and decoding of Set Mode Payload. Added new type
976 SilcSetModePayload. Moved the definitions of different modes
977 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
979 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
981 * Oops, a little mistake in server's connection authentication
982 protocol. The protocol is not ended with FAILURE but with
983 SUCCESS if the authentication is Ok. :) Affected file is
986 * Implemented NICK_CHANGE notify handling in server in the file
987 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
988 the local clients on the channel. After the changing nickname
989 in router environment snhould work and the [<unknown>] nickname
990 should appear no more.
992 The silc_server_replace_id function that receives the Replace ID
993 payload now sends the NICK_CHANGE notify type also in the file
994 silcd/packet_receive.c
996 * Changed WHOIS and IDENTIFY command to support the maximum amount
997 of arguments defined in protocol specs (3328 arguments). This
998 fixed a bug that caused problems when there were more than three
1001 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1003 * Added extra parameter, command identifier, to the
1004 silc_client_send_command so that explicit command identifier
1007 Changed that ID list routines uses specific command identifier
1008 when sending WHOIS/IDENTIFY requests to the server so that they
1009 can be identified when the reply comes back.
1011 Affected files lib/silcclient/command.[ch],
1012 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1014 * Added `sender' argument to silc_server_packet_send_to_channel
1015 to indicaet the sender who originally sent the packet to us
1016 that we are now re-sending. Ignored if NULL. Affected file
1017 silcd/packet_send.[ch].
1019 * Added some server statistics support in silcd/server_internal.h
1020 SilcServerStatistics structure and around the server code. Also
1021 send some nice statistics information when client is connecting
1024 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1026 * Fixed channel ID decoding in server's JOIN command reply in
1027 silcd/command_reply.c
1029 * Fixed braodcasting of replace ID payload to not to send it if
1030 we are standalone server in silcd/packet_receive.c.
1032 * Fixed all channel message sending routines to not to send
1033 packets to clients that has router set, since they are routed
1034 separately in the same function earlier. Affects file
1035 silcd/packet_send.c and all channel packet sending functions.
1037 * In USERS reply, res_argv[i] are not allocated, the table
1038 is allocated. Thus changed that free the table, not its
1041 * In server's whois_check and identify_check if the client is
1042 locally connected do not send any WHOIS commands - they are not
1045 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1047 * Fixed some minor bugs in client when sending WHOIS command. The
1048 arguments was in wrong order.
1050 * Removed statis function add_to_channel from server in
1051 silcd/command.c that was previously used with the joining but
1054 * Tested USERS command in router environment successfully with two
1055 routers, two servers and two clients.
1057 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1059 * Reorganized the USERS command and command reply in client library
1060 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1061 When the command is given by user we register a pending command
1062 callback that will reprocess the command after the reply has been
1063 received from the server. When reprocessing the packet we then
1064 display the information. Thus, the USERS information is displayed
1065 now in the command callback instead of in the command reply
1066 callback. The processing of the command is same as previously
1067 when server has sent the command reply in the JOINing process.
1069 * Added to USERS command in silcd/command_reply.c to join the client,
1070 we didn't use to know about, to the channel after we've created
1071 a client entry for it. Also, for clienet we did know already still
1072 check whether it is on the channel or not and add it if not.
1074 * Removed silc_server_command_join_notify as the function and its
1077 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1079 * Changed the client's pending command handling to the same as the
1080 server's pending command handling. It is also now possible to
1081 execute command reply functions from other command reply
1082 function as the function callbacks for commands and command
1083 replies are one and same. The pending commands are not static
1084 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1085 in client connection context. Thus, pending commands are server
1086 connection specific as it is convenient.
1088 Changed the function silc_client_command_pending and
1089 silc_client_command_pending_del and added new function
1090 silc_client_command_pending_check. Removed the
1091 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1094 * Added cmd_ident, current command identifier, to the client
1095 connection context in lib/silcclient/client.h to keep track on
1096 command identifiers used in command sending. Client's command reply
1097 function handling now supports the mandatory command identifiers.
1099 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1100 funtions in client to fully support pending command callbacks.
1102 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1103 as one of the arguments to the application in the command reply
1106 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1107 before first releasing SILC but came back. Now it is removed again
1108 and should come back nomore. The FORWARDED flag was used only
1109 by the JOINing procedure by forwarding the command packet to router.
1110 Now, the JOINing procedure has been changed to more generic (due
1111 to various router environment issues) and FORWARDED is not needed
1112 anymore for anything. The protocol specification is yet to be
1115 Now, removed silc_server_packet_forward from server and the flag
1116 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1118 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1120 * Renamed NAMES command to USERS command. The NAMES was named that
1121 due to historical reasons. Now it is renamed. Also, rewrote
1122 parts of the USERS command. The nickname list is not sent anymore
1123 by the server. Only Client ID and mode lists are sent in the USERS
1124 command. Changed this also to the protocol specification.
1126 The client now resolves the names and stuff after it receives
1127 the USERS list from the server when joining to the channel.
1129 * WHOIS and IDENTIFY commands has been changed to support multiple
1130 Client ID's per command. One can now search for multiple users
1131 in the network by sending only one WHOIS or IDENTIFY command.
1132 Changed the code and the protocol specifications.
1134 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1135 uses silc_server_command_whois_parse to parse the request. */
1137 * If normal server, do not parse the WHOIS and IDENTIFY requests
1138 before sending it to the router. Saves some time.
1140 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1142 * Fixed JOIN command on client library. Wrong number of arguments
1143 used to crash the client.
1145 * Added silc_server_channel_has_global function to check whether
1146 channel has global users or not.
1148 * Added silc_server_channel_has_local function to check whether channel
1149 has locally connected clients on the channel.
1151 * The silc_server_remove_from_one_channel now checks whether the
1152 channel has global users or not after given client was removed from
1153 the channel. It also checks whether the channel has local clients
1154 on the channel anymore. If it does not have then the channel entry
1155 is removed as it is not needed anymore.
1157 * The silc_server_notify now checks on JOIN notify whether the joining
1158 client is one of locally connected or global. If it is global then
1159 the channel has now global users on the channel and that is marked
1160 to the channel entry. Also, it now saves the global client to
1161 global list who is joining and JOINs it to the channel. This is
1162 for normal server, that is.
1164 Changed silc_server_send_notify_on_channel,
1165 silc_server_packet_relay_to_channel and
1166 silc_server_packet_send_to_channel check if we are normal server
1167 and client has router set (ie. global client) do not send the
1168 message to that client, as it is already routed to our router.
1170 * Implemented LEAVE notify type handling in silc_server_notify
1173 * Tested LEAVE command in router environment successfully. Tested
1174 with two routers, two servers and two clients.
1178 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1180 * Implemented SIGNOFF notify type handling in silc_server_notify
1183 * silc_server_remove_id now removes the client entry from all channels
1184 it has joined and thusly sends SIGNOFF notify type.
1186 * Rewrote the NAMES list generation in server by removing two excess
1187 loops. The lists are created now inside one loop.
1189 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1191 * silc_server_remove_channel_user checks now also global list
1192 for channel and client.
1194 * silc_server_new_channel_user checks now both local and global
1195 list for channel and client. Fixed a bug in client id decoding.
1196 Used to decode wrong buffer.
1198 * silc_server_channel_message checks now both local and global
1199 list for channel entry.
1201 * Tested channel joining (hence JOIN) in router environment
1202 successfully. Tested with two routers, two servers and two
1205 * Tested channel message sending in router environment successfully.
1207 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1209 * Added silc_server_save_channel_key into server.[ch] to save the
1210 received channel key in Channel Key payload processing. It is
1211 also used in JOIN command reply handling.
1213 Equivalent function silc_client_save_channel_key added into
1214 client.[ch] into client library.
1216 * Changed JOIN command reply to send information whether the channel
1217 was created or not (is existing already) and the channel key
1218 payload. Changed protocol specs accordingly.
1220 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1221 the request was sent by ID and not by nickname. Crashed on
1224 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1226 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1227 now correctly save the received data.
1229 * silc_server_free_sock_user_data now notifies routers in the
1230 network about entities leaving the network.
1232 At the same time implemented functions silc_server_remove_id
1233 and silc_server_send_remove_id to receive and send REMOVE_ID
1234 packets. The packet is used to notify routers in the network
1235 about leaving entities. The ID removed will become invalid in
1238 * Added function silc_idlist_del_server into server. Removes and
1239 free's server entry from ID list.
1241 * silc_server_private_message function now checks, if we are router,
1242 that the destination ID really is valid ID, naturally.
1244 * In router when NEW_ID packet is received (for new client) the
1245 hash of the Client ID is saved in the ID Cache but the
1246 client->nickname is set to NULL, instead of putting the hash
1249 IDENTIFY command now also checks that client->nickname must be
1250 valid. If it is not if will request the data from the server who
1251 owns the client. Added new function
1252 silc_server_command_identify_check.
1254 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1255 to set the command to already allocated Command Payload.
1257 * Tested private message sending in router environment with two
1258 routers, two servers and two clients. Fixed minor bugs and now
1261 * Fixed segfault from client's NAMES command. Used to crash if
1264 * Forwarded packets must not be routed even if it is not destined
1265 to the receiver. Changed server code comply with this.
1267 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1269 * Added `require_reverse_mapping' boolean value to ServerParams
1270 structure. If TRUE (not default) the server will require that
1271 the connecting host has fully qualified domain name.
1273 If the reverse mapping is not required and hostname could not be
1274 found the IP address is used as hostname.
1276 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1278 * Implemented version string checking to both client and server.
1279 The check is incomplete currently due to the abnormal version
1280 strings used in development version of SILC.
1282 * Changed all command functions in server to use the new
1285 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1287 * Changed char *data to unsigned char *data in ID Cache system to
1288 support binary data as ID Cache data. Changed code to support
1289 binary data in lib/silccore/idcache.c.
1291 * Renamed silc_server_packet_relay_command_reply to
1292 silc_server_command_reply as it is normal packet receiving
1293 function. Rewrote the function to accept command replys for
1294 servers and not only for clients.
1296 * Mark remote router always as registered server if we are connecting
1297 to it. Otherwise, commands sent by the router to us are ignored.
1299 * All ID List find routines now returns the ID Cache Entry pointer
1300 as well if requested.
1302 * WHOIS command works now in router environment, tested with two
1303 routers, two servers and two clients.
1305 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1306 in router environment (as it is almost equivalent to WHOIS) but
1307 hasn't been tested thoroughly. Added new functions:
1309 silc_server_command_identify_parse
1310 silc_server_command_identify_send_reply
1311 silc_server_command_identify_from_client
1312 silc_server_command_identify_from_server
1314 * Disabled route cache adding because adding two different ID's with
1315 same IP replaces the old cache entry thus giving wrong route.
1316 The entry->router->connection is always the fastest route anyway
1317 so route cache may not be needed. Of course, new routes maybe
1318 established after receiving the ID when the entry->router->connection
1319 might not be anymore the most optimal.
1321 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1323 * Add route cache for received ID for fast routing.
1325 * Added silc_server_packet_route to route received packet on router
1326 that is not destined to us.
1328 * Renamed silc_server_get_route to silc_server_route_get.
1330 * Added id_string and id_string_len fields into SilcServer to
1331 include encoded ServerID for fast comparing without excess
1332 encoding of the ID's.
1334 * Cleaned up WHOIS command on server side. Added following static
1337 silc_server_command_whois_parse
1338 silc_server_command_whois_check
1339 silc_server_command_whois_send_reply
1340 silc_server_command_whois_from_client
1341 silc_server_command_whois_from_server
1343 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1344 arguments in command replies. All command functions should be
1345 updated to use this macro.
1347 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1349 * Minor typo fixes on command reply handling on server.
1351 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1353 * Added silc_server_command_add_to_channel internal routine to add
1354 the client to the channel after router has created the channel and
1355 sent command reply to the server.
1357 * Added generic silc_server_send_command to send any command from
1360 * Use static buffer with ID rendering instead of duplicating data.
1362 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1364 * Fixed a channel user mode bug when joining to a channel server gave
1365 everybody channel founder rights, oops.
1367 * We mark ourselves as the router of the incoming server connection
1368 if we are router ourselves. This way we can check in some packet
1369 sending functions whether it is locally connected server. For
1370 incoming router connections we put NULL.
1372 * For router sending packets locally means now always sending the
1373 packet cell wide; to local clients and local servers. For normal
1374 server sending packet locally means sending it to only local
1377 * Fixed the JOIN command to really work in router environment. If the
1378 channel is created it is always created by the router. Router is
1379 also responsible of making the initial joining to the channel,
1380 sending JOIN notify to the sending server and distributing
1381 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1382 does not exist server doesn't do anything else but forward the
1383 command to the router which performs everything.
1385 * Added silc_server_send_channel_key function to send the Channel Key
1388 * Added silc_server_create_channel_key to create new channel key. The
1389 channel key is now re-generated everytime someone joins or leaves
1390 a channel, as protocol dictates. Note: channel->key_len is the
1393 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1395 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1396 packet_receive.[ch] to separate packet sending and receiving
1397 routines. The server.[ch] now includes everything else including
1398 actual packet processing (writing and reading data) and other
1401 Renamed silc_server_private_message_send_internal to
1402 silc_server_send_private_message. The routine is still though
1403 used only to relay private messages as server does not send
1404 private messages itself.
1406 Renamed silc_server_new_channel to silc_server_create_new_channel
1407 and added new function sicl_server_new_channel that handles the
1408 incoming New Channel packet. Added also new sending function
1409 silc_server_send_new_channel to send New Channel Payload.
1411 * Added new function silc_server_notify to process incoming notify
1412 packet to the server/router. Server may then relay the notify
1413 to clients if needed.
1415 * Added new function silc_server_new_channel_user to process incoming
1416 New Channel User packet. Router will redistribute the packet and
1417 send JOIN notify to its local clients and locally connected servers
1418 if needed. Normal server will send JOIN notify to its local client
1419 on same channel when received this packet. Added also corresponding
1420 sending function silc_server_send_new_channel_user to sent the
1423 * Added boolean route argument to send_notif_to_channel and
1424 packet_send_to_channel functions to attempt to route the packet
1425 if it is TRUE and send only locally if it is FALSE.
1427 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1429 * silc_server_replace_id now broadcasts the received replace ID
1430 packet if it is not broadcast packet already. The router must
1431 broadcast to inform other routers about changed ID.
1433 * Added backpointer to server's router into SilcServer context in
1434 silcd/server_internal.h.
1436 * Fixed silc_server_packet_broadcast to send correct broadcast
1439 * The channel key is now distributed to the local client as soon
1440 as it is received from the router (in router environment) so that
1441 no other packet may be sent for the channel until client has
1444 * silc_server_remove_channel_user now broadcasts the received
1445 Remove Channel User packet if it is not broadcast packet already.
1446 The router must broadcast to inform other routers about removed
1449 * Added users field into SilcPacketContext that is a reference count
1450 of the context. One can increase the reference count by calling
1451 silc_packet_context_dup which is now changed to just increase the
1452 reference count instead of duplicating the data. The reference
1453 count is decresed by calling silc_packet_context_free that will
1454 free the data after the reference count hits zero.
1456 For now on the packet context and everything allocated into it
1457 (including the raw packet from network) must be freed by calling
1458 the new silc_packet_context_free function. Added also new function
1459 silc_packet_context_alloc that must be used now to allocate the
1460 context. This also means that if a routine is asynchronous from
1461 silc_[client/server]_packet_parse_type the packet context must
1462 be duplicated by calling silc_packet_context_dup. Otherwise it
1463 gets free'd after silc_[client/server]_packet_parse_type returns.
1464 Also, one must remember that if packet is duplicated then its
1465 reference count must be decresed by calling the free function as
1466 many times as it was duplicated.
1468 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1469 from both client and server.
1471 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1473 * Made joining to a channel working in router environment.
1475 * Cleaned up JOIN command on server side and create function
1476 silc_server_command_join_channel internal routine to make the
1479 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1481 * Changed silc_command_pending list to SilcDList. Also, added
1482 `ident' field to SilcServerCommandPending structure to identify
1483 the reply and to call correct callback.
1485 Added silc_server_command_pending_check function to replace the
1486 corresnponding macro. The silc_command_pending list is not
1489 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1490 to set identifier to previously allocated Command Payload. It
1491 is used to set identifier for command when resending Command
1494 * Added silc_command_payload_encode_payload to encode Command
1495 Payload buffer from SilcCommandPayload structure.
1497 * Added silc_argument_payload_encode_payload to encode Argument
1498 payload buffer from SilcArgumentPayload structure.
1500 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1502 * Changed WHOIS command to support router connection on server side.
1503 The whois request is always sent to router unless the server is
1504 standalone server. After server has received the reply from the
1505 router will it send the reply to the client.
1507 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1508 broadcast received broadcast packet. The function is used only
1509 by router. The broadcast packet is always sent to the router's
1512 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1513 render given ID to printable string, for log files for example.
1515 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1517 * Made basic router to router connections working. At least they
1518 can now connect to each other but nothing really works the way
1519 they are supposed - yet.
1521 * Added new initiator token to RouterConnection configuration
1522 file in silcd/serverconfig.[ch]. It is used to tell whether we
1523 are the initiator to the remote router or whether we'll expect
1524 the other end to connect.
1526 * Moved registering of listener task to silc_server_init, hence
1527 the server starts listenning as soon as it is run, even if it
1528 does not have connections to other routers. Let's see how well
1531 * Changed default connection retry timeouts for more suitable in
1534 * Removed cipher and such arguments from silc_idlist_add_client
1535 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1536 Added new function silc_idlist_add_data to add the keys and stuff
1539 * Added SilcIDListData structure and added it to SilcClientEntry
1540 and SilcServerEntry as their first field in the structure. This
1541 way we can explicitly cast the ID entries to the SilcIDListData
1542 structure and get common data for the entries. In past, we had
1543 to first check what type of connection it is and then cast it to
1544 correct ID entry type. Now, we can directly cast the opaque
1545 pointer to the SilcIDListData (no matter what ID entry it actually
1546 is) and get the data needed.
1548 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1550 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1551 in some circumstances even if threre were timeout tasks, though not
1552 IO tasks, but tasks anyway. Now fixed.
1554 * Defined SilcServerConnection structure to hold connection specific
1555 stuff about directly connected servers and routers. The definition
1556 is currently in silcd/server_internal.h. I thought about having
1557 a bit more important role fro this struct but for now it is used
1558 only when connecting to other server (or router actually).
1560 * Added connecting retry support in server when connecting to
1561 router(s). The retry feature implement exponential backoff
1562 algorithm. Also, added SilcServerParams structure to hold default
1563 parameters for server. For now, it include these retry settings
1564 and are hard coded. After server is moded to be as Silc Server
1565 Library this structure will be more important.
1567 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1569 * Changed client librarys channel->clients table to SilcList and
1570 changed code accordingly.
1572 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1574 * Changed client's channel table to SilcList and changed code
1575 accordingly. Also changed SilcChannelClientEntry to include back-
1576 pointer to the channel so that client entry can use that structure
1577 as list as well and we have fast cross-reference to the channel.
1578 This change dramatically decreased the complexity of channel
1579 handling with client entry and vice versa (removed one extra
1580 loop when searching for channel entry from many functions).
1582 * Changed server->sim from table to SilcDList and changed code
1585 * NAMES command can now be used from user interface. It will show
1586 the user list on the channel, neatly.
1588 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1589 Code now saves realname of the user if it becomes available.
1591 * Renamed configure.in to configure.in.pre and made ./prepare
1592 script to automatically add correct version string to
1593 configure.in which it creates from configure.in.pre.
1595 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1597 * NAMES command reply now shows users mode with the nickname when
1600 * Moved silc_client_ch[u]mode[_char] functions from
1601 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1602 place sucks, they are utility functions and should be in some
1605 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1607 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1610 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1614 * Added TRQ (efficient deque and list library) into lib/trq. This is
1615 a very good list library that is currently used in the SILC. Defined
1616 SilcList API over the library because I didn't like the API very
1617 much. See lib/trq/silclist.h for the API and examples of how to
1618 use the API. Fixed various places in the code to use the new
1619 SilcList API. The SilcList is meant for lists that has a structure
1620 already defined as a list. It is not suitable to add just some
1621 context to the list (in TRQ, the context is the list actually).
1623 So, I defined SilcDList that can be used for the purpose where
1624 predefined list structure does not exit. This can be used as
1625 such list. Now some context just can be added to the SilcDList.
1626 Currently this list is not used in the SILC just yet, though there
1627 are a lot places where this can replace dynamically allocated
1628 tables and I will fix these places, later, to use SilcDList.
1629 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1630 and use TRQ internally).
1632 Also fixed some annoying warning messages that the original TRQ
1633 code generated. Also minor changes to TRQ's Makefile.in.
1635 * Added support for querying by Client ID to both WHOIS and
1636 IDENTIFY commands into server, as required by the protocol.
1638 * Removed method function pointers from SilcBuffer structure. They
1639 weren't used to anything and just increased the context size for
1640 no good reason. This change also made silc_buffer_alloc and
1641 silc_buffer_free functions inline functions.
1643 * Disabled command flooding detection support until it's fixed so
1644 that it accepts commands in but does not execute them more than once
1647 * Added silc_net_localhost(), to return local hostname, into
1648 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1649 that must be initialized before calling silc_client_init.
1651 * Added new function: silc_server_send_notify_on_channels to send
1652 notify messages to all channels client has joined. It is assured
1653 that the message is sent only once per client.
1655 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1656 lib/silcutil/silcutil.[ch] as silc_format function. The new
1657 function is generic and is used by server as well, not only by
1658 the logging routines.
1660 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1661 the provided version string was not acceptable. Added new function:
1662 silc_ske_check_version into lib/silcske/silcske.h. The function
1663 must be implemented by the application (client or server) and it
1664 does not reside in the SKE library. The function checks the version
1665 string remote end sent.
1667 * Added back pointers (to opaque context and to SilcSocketConnection)
1668 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1670 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1671 duplicate packet context structure.
1673 * Changed `notify' client operation to send same arguments as client
1674 receives from server except for ID's. ID's are mapped to correct
1675 ID entry and that is returned. Also, if channel entry is not sent
1676 by server but the notify is for channel the channel entry is sent
1677 to application (otherwise application doesn't know that it is for
1678 channel (library gets it from packet's Destination ID)).
1680 * Added silc_client_remove_from_channels into client library to
1681 remove a client from all channels it has joined to. Used when
1682 received SIGNOFF notify from server. Added also new function
1683 silc_client_replace_from_channels to replace old ID entry with
1684 new ID entry on all channels. Used when received NICK_CHANGE
1687 * Fixed ID Cache list handling in silc_idlist_get_client in
1688 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1689 to get (or query) client by ID.
1691 * Updated TODO list.
1693 * Added connection authentication status message defined by the
1694 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1695 support for these into the code in client and server side.
1697 * Added generic function silc_client_send_command to send any command
1698 with variable argument list. Application should use this function
1699 to send commands if the command functions provided by the library
1700 does not suite for the application's user interface needs.
1702 * Added new `failure' client operation. Application is notified about
1703 received failure packet if client is executing a protocol. In this
1704 case the protocol's execution has failed.
1706 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1707 is required by the protocol.
1709 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1710 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1713 * Added status flag to SilcSKE object to indicate realtime status
1714 of the SKE protocol.
1716 * Application receives now exactly same command reply arguments as
1717 the library receives from server. However, if ID is received the
1718 corresponding ID entry is returned to the application (eg. Client
1719 ID is mapped to correct SilcClientEntry entry and that is returned).
1720 Changed command_reply client operation due to this change.
1722 * Changed all ID's in commands and in command replys as ID Payloads.
1723 Change affected both client and server side codes.
1725 All ID's sent in SILC network (with execption of ID's in SILC
1726 Packet header) are sent in ID Payload to support variable length
1729 * Server now notifies nick changes and notifies all clients on
1730 the channels about the new nickname (about the new Client ID,
1733 * Implemented CMODE command to change channel modes. Supports all
1734 channel modes defined by the protocol specs except ban and invite
1735 lists. (Also, private channel key mode is supported but support for
1736 setting private channel key in client is missing, thus, this mode
1737 has no effect on client side (except that server requires that the
1738 client uses private channel key and normal channel traffic does not
1741 Also, invite mode works per se, but INVITE command does not work
1742 yet correctly, so you can set channel as invite only channel but
1743 inviting clients to the channel does not work (it is yet to be
1744 thought what's the best way to do it).
1746 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1747 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1748 Implemented CUMODE command to change user's mode on the channel.
1749 Supports all modes defined by the protocol specs.
1751 * Added NAMES command reply to return users modes on the channel.
1753 * Removed unnecessary and slow ciphers from lib/silccrypt.
1755 * Set SO_KEEPALIVE option to connection sockets by default.
1757 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1759 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1760 redefined the Notify Payload into protocol specs.
1762 * Added silc_id_payload_parse_id to get ID directly from raw
1765 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1767 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1768 accept searching by Client ID as well.
1770 * Added support for LEAVE and SIGNOFF notify types in client library.
1772 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1773 to parse ID Payload from raw data.
1775 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1777 * Added flags parameter into silc_ske_assemble_security_properties
1778 function in lib/silcske/silcske.[ch].
1780 * Changed notify client operation to fit better for notify messages
1781 sent by server. The notify payload received from server is now
1782 passed to the application (after parsing it to SilcNotifyPayload).
1783 It is application's responsibility to retrieve the arguments
1784 from the payload and show the message the way it wants. The message
1785 sent by server is implementation specific.
1787 * Changed public keys to comply with the protocol specification.
1788 Old public keys are not supported anymore and are not compatible.
1790 * Removed nickname from Channel Payload as the latest draft removed
1791 it. The client must resolve the nickname from the NAMES command
1792 reply received when it joined the channel.
1794 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1796 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * Fixed some errors in protocol specification drafts.
1800 * Created lib/silccore/silcnotify.c to implement Notify Payload
1801 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1802 generic payloads described by protocol specifications. The file
1803 includes implementations for ID Payload and Argument Payload.
1805 * Changed Command Payload implementation to use the new Argument
1806 Payload. Changed command_xxxx_payload to command_payload_xxxx
1807 to comply with SILC coding conventions.
1809 * Added suppport for Argument Payload handling in Notify Payload
1810 implementation as protocol requires it. Added the new support
1811 into server and client lib as well.
1813 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1815 * Added support for multiple nicknames on same channel. [n] is
1816 added locally to the nickname if there are more than one same
1817 nicknames on the channel.
1819 * Server now sends all nicknames that matched WHOIS request.
1820 Client also shows the list received from server.
1822 * Added TOPIC command to client side. User can now set and show
1823 current topic on channel.
1825 * Added MOTD command to client and server. Also, server sends the
1826 motd when client connects to the server.
1828 * Changed version strings to comply ISO 8601.
1830 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1832 * Fixed protocol error handling in client library. It should now
1833 cope even if the SKE fails for some reason.
1835 * Made new protocol specification drafts for submitting to IETF.
1837 * Implemented TOPIC command to server in silcd/command.c.
1839 * Added two new notify types into lib/silccore/silcnotify.h:
1840 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1841 notify nickname change and topic setting/change on a channel.
1843 * API change of command_reply operation in client library. The
1844 application gets now the status type received from server as well.
1846 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1848 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1850 * Cras fixed and optimized the packet handling even further and
1851 it should work now. Minor change to the prototype of function
1852 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1854 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1856 * Added new function into lib/silcutil/silcschedule.[ch]:
1857 silc_schedule_with_fd to select() a specified fd. The function
1858 returns after timeout expires or data arrives or goes. The
1859 function is used by packet routines to wait that all data is
1860 received from network.
1862 * Fixed data reading from network in lib/silccore/silcpacket.c.
1863 The code now assures that all data is read from the fd and then
1864 continues packet processing. This was a bug fix since the code
1865 used to drop some data in some circumstances.
1867 * Added new function into lib/silcclient/client.[ch]:
1868 silc_client_start_key_exchange to start key exchange after
1869 connection has been established to server. The code internally
1870 now uses this funtion but its main purpose was to provide it
1871 for applications that perform their own connecting. After
1872 application has created a connection it merely calls this
1873 function to start the key exchange between client and server.
1874 The library takes care of everything else after that.
1876 Updated also lib/silcclient/README to explain the usage of
1879 * Do not send to application information that connection has
1880 been established. Application gets notified it by connect
1883 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1885 * Applied cras's patch to add silc_schedule_one function. The
1886 function runs scheduler once and returns.
1888 * Fixed the scheduler after cras messed it up. The timeout
1889 handling works now as it's supposed to work.
1891 * Added into lib/silccore/ silcnotify.h to include notify
1892 message types support. Changed silc_server_send_notify*
1893 functions, in server.[ch], to support those new notify types.
1894 Added the support for the notify types into client library,
1895 as well. Added new notify client operation into ops.h in
1898 * Changed silc_server_packet_send_to_channel to send normal
1899 packets instead of just channel message packets. The function
1900 is now used to send the notify packets to channels. It is not
1901 used to send channel message packets anymore, as server never
1904 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1905 va_arg()s as it seems to require it nowadays. I guess, if SILC
1906 is compiled with older va_arg() the new code should work anyway.
1908 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1910 * Splitted core library. Core library (lib/silccore) includes
1911 now only SILC protocol specific core (and common) components.
1912 Created new utility library (lib/silcutil) that includes more
1913 generic purpose stuff. The stuff for util library was taken
1914 from the old core library. This was minor and easy split.
1916 * Created SILC Client Library (lib/silcclient) that includes
1917 implementation of the SILC client without user interface. This
1918 was major move from silc/ directory. The code has been changed
1919 so that it is transparent towards the user interface. The
1920 silc/ directory includes now the same user interface as before
1921 and it uses the new client library. Read lib/silcclient/README.
1922 Basicly, the client library performs everything else related
1923 to SILC except user interface handling. Also, configuration
1924 files are considered to be part of user interface and library
1925 does not handle them.
1927 This change also changed a lot of structures, function naming etc.
1928 Most important change was that SilcClientWindow object was
1929 renamed to SilcClientConnection in the client library. Created
1930 also new file lib/silcclient/ops.h. Also added new files
1931 silc/local_command.[ch] and silc/client_ops.[ch].
1933 All these changes were made to make it easier for user interface
1934 designers to create what ever user interface for the SILC client
1937 It is also expected that the server will be moved to lib
1938 directory as well and SILC Server Library will be created;
1939 sometimes in the future.
1941 * Removed Local commands from lib/silccore/silccommand.h as
1942 they are application specific and new client library does not
1943 handle any of those anymore.
1945 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1946 old client implementation in silc/.
1948 * Added support for callback functions in SILC_LOG_* macros.
1949 Application can now set its own callbacks that will be called
1950 instead of using the default functions that will always print
1951 the debug messages to stderr (or stdout). Also, debugging can
1952 now be disabled by setting silc_debug to FALSE and re-enabled by
1953 setting it to TRUE. Note, that logging will still work even
1954 if debugging is disabled.
1956 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1957 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1958 silc_log_reset_debug_callbacks.
1960 * To enable debugging in silc client one must give now -d
1961 option on command line.
1963 * Changed silc_schedule_init to automatically allocate task queues
1964 if they are not allocated before calling it.
1966 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1968 * Added GMP 3.1 into math library.
1970 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1972 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1973 a channel in SILC network. The packet is used by servers and
1974 routers to notify other routers that user has left a channel.
1975 This little feature was missing until now. Added the feature
1976 to protocol specification as well.
1978 Added functions: silc_server_send_remove_channel_user and
1979 silc_server_remove_channel_user into server.[ch].
1981 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1982 lib/silccore/silcpacket.h. However, they are not implemented
1985 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1987 * Fixed joining to a channel and sending channel messages
1988 between server and router. The channel message sending should
1989 now work inside a cell.
1991 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1993 * Fixed the private message sending between server and router.
1994 The private message sending should now work inside a cell.
1996 * Added silc_server_replace_id into server.[ch] to replace
1997 existing ID in the SILC network.
1999 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2000 and silc_idlist_replace_server_id into idlist.[ch] in server.
2002 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2004 * Fixed the server to server connections. Server can again now
2005 connect to router. Router to router connections probably does
2008 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2010 * Added dynamic protocol registering support. Now protocols can
2011 registered and unregistered on the fly. Patch by cras.
2013 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2015 * Added lib/contrib directory to hold routines that some platforms
2016 don't have but are needed by SILC.
2018 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2019 into lin/contrib to provide getopt() and getopt_long() for
2020 those who don't have it.
2022 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2024 * Added AWAY command to client. When away message is set and
2025 client receives a private message packet the client automatically
2026 replies to the sender with the away message.
2028 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2029 bug seemed to be the cause of recent problems when compiling
2032 * Added version detection support to SKE protocol specification
2033 and added the new changes to the SKE implementation as well.
2034 There were other minor changes in the SKE protocol as well.
2036 Many changes in lib/silcske/silcske.[ch] and in
2037 lib/silcske/payload.[ch].
2039 * Added ^U functionality, clear input line. Patch from cras.
2041 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2043 * Mainly small bugfixes on core library. Fixed some debugging
2044 logging and buffer overflow in silclog.c.
2046 * Updated config.sub and config.guess on the distribution tree.
2048 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Added command lagging support in server. Client may execute
2051 commands now only once in two seconds.
2053 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2055 * Optimized packet reception. MAC computation and checking is now
2056 also more optimized. A lot previously duplicated code is now
2057 used as generic by both client and server.
2059 * Fixed key pair generation in clientutil.c
2061 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2063 * Added into lib/silccore/silcbufutil.[ch] new function;
2064 silc_buffer_realloc.
2066 * Moved generic packet sending/encryption functions to
2067 lib/silccore/silcpacket.[ch] from client and server. Some
2068 rewriting of the functions.
2070 * Moved all generic packet reception/decryption functions to
2071 lib/silccore/silcpacket.[ch] from client and server. The
2072 packet processing is now much cleaner in both client and server.
2073 These were major changes in both client and server.
2075 * Created many common functions in server to do packet sending.
2076 Previously code were duplicated a lot, this has been removed
2079 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2081 * Rewrote major parts of the ID cache system. Don't know
2082 whether it is better now or not but at least the API is more
2085 * Major rewrite on ID cache stuff on client because of the ID
2086 cache API changes. Added idlist.c to client.
2088 * Also major rewrite on ID cache stuff on server as well.
2089 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2090 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2091 in hand, instead they are all put into the ID cache system now.
2092 All server_idlist_* routines uses ID cache now instead of
2093 traversing its own lists (those lists does not exist anymore).
2094 SilcIDList though still exists. Also, SilcXXXEntry's are
2097 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2099 * Finally made the SKE implementation compliant to the protocol
2100 specification. All mp integers are now binary encoded as
2101 opposed being HEX encoded.
2103 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2106 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2107 functions: silc_[encode/decode]_pem. Also added function
2108 silc_encode_pem_file to PEM encode with newlines ('\n') for
2111 * SILC public keys are now encoded either PEM or binary. Same
2112 option is for private keys as well. By default private keys
2113 are binary encoded and public keys PEM encoded. Silly HEX
2114 encoding were removed.
2116 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2117 function to create fingerprints.
2119 * Fixed a bug in SHA1; does not change the original data anymore.
2121 * Partly implemented INFO command on client and server side.
2122 Fixed CLEAR command. Changes to SERVER command; show current
2123 server(s) when giving command without arguments. Added
2124 VERSION command to client.
2126 * Added check to server that unregistered connections cannot
2127 execute commands (unless it is specificly allowed).
2129 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2131 * Fixed screen refresh.
2133 * Fixed channel joining bug from client. On some circumstances
2134 client tried to join to a channel it had already joined.
2136 * Added public key verification process into client's protocol.c.
2137 The client now verifies the public key from user and saves
2138 it into ~./silc/serverkeys/ directory.
2140 Added into: clientutil.[ch]: silc_client_verify_server_key.
2142 * Changed SKE protocol's silc_ske_initiator_finish function
2143 to accept callback function that verifies the received public
2144 key. Removed old silc_ske_verify_public_key function.
2146 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2148 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2149 silc_pkcs_private_key[_data]_set.
2151 * Made the password and public authentication more cleaner in
2152 server's protocol.c.
2154 * Removed historic and obsolete protocol `channel_auth' from
2155 both client and server.
2157 * Removed wrong way of sending command status messages from
2158 server to client in server's command.c. The old way violated
2159 protocol specification.
2161 Changes to silccore/silccommand.[ch]: removed
2162 silc_command_encode_status_payload -> not needed anymore,
2163 changed silc_command_encode_payload_va to accept extra
2164 argument on variable argument list. The argument type must
2165 now be provided to the function. Also, added new function:
2166 silc_command_encode_reply_payload_va which is same as
2167 normal command_encode_payload_va except command status type
2168 is provided as extra argument.
2170 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2172 * Added ~./silc directory handling. The directory includes the
2173 public and private keys for the client.
2175 Added silc_client_check_silc_dir, silc_client_create_identifier
2176 and silc_client_load_keys.
2178 * Implemented SILC protocol compliant public key. Added public
2179 and private key saving to and loading from files.
2181 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2182 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2183 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2184 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2185 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2187 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2188 silc_pkcs_load_[public/private]_key.
2190 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2192 * Added silc_server_get_route (route.[ch]) to get connection
2193 data for the fastest route for given ID.
2195 * Implemented INVITE command on client and server. The command
2196 were re-defined in the SILC Protocol Specification and the
2197 implementation now complies with the specification.
2199 * Implemented PING command on client and server.
2201 * Implemented NAMES command on client and server. The server side
2202 supports currently only normal server not router server yet.
2203 Some changes to NAMES definition in SILC protocol specification.
2205 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2207 * Implemented LEAVE command on client and server.
2209 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2210 again. This change was made to the protocol as well. Server
2211 should not violate the protocol specification anymore.
2213 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2215 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2216 was tested. SOCKS4 was not but should work anyway.
