3 * Added silc_client_get_clients_by_list to get client entries
4 from Client ID list, that is returned for example by JOIN
5 and USERS command replies. The application should use this
6 function for example when JOIN command reply is received to
7 resolve the clients already on the channel (library does not
8 do that anymore as USERS command reply is not used in the JOIN
9 procedure anymore). Affected files lib/silcclient/silcapi.h and
10 lib/silcclient/idlist.c.
12 * JOIN command reply and USERS command reply returns now SilcBuffer
13 pointers instead of unsigned char pointers when returning
14 the client list and mode list.
16 * Added <Client ID> argument to the JOIN command reply, mainly
17 for the server to identify for which client the command was
18 originally sent. Updated protocol specs accordingly.
20 * Added SilcDlist private_key pointer to the SilcChannelEntry
21 in the client to support the channel private keys. Affected
22 file is lib/silcclient/idlist.h.
24 * Added SilcChannelPrivateKey argument to the function
25 silc_client_send_channel_message so that application can choose
26 to use specific private ke if it wants to. If it is not provided,
27 the normal channel key is used, unless private keys are set.
28 In this case the first (key that was added first) is used
29 as the encryption key.
31 * Implemented the support for channel private key handling.
32 Implemented the following functions:
34 silc_client_add_channel_private_key,
35 silc_client_del_channel_private_keys,
36 silc_client_del_channel_private_key,
37 silc_client_list_channel_private_keys and
38 silc_client_free_channel_private_keys
40 Affected file lib/silcclient/client_channel.c.
42 * Added the support for the private keys in the channel message
43 sending and encryption and in the message reception and
44 decryption. Affected funtions are
45 silc_client_send_channel_message and silc_client_channel_message.
47 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
49 * Added SKE's key verify callback to the client library's
50 KE protocol context. Affected files lib/silcclient/protocol.[ch].
52 * Removed the statement that server (or router) must send USERS
53 command reply when joining to the channel so that the client
54 knows who are on the channel. Instead, the client list and
55 client's mode list is now sent in the JOIN command reply to the
56 client who joined channel. This is better solution.
58 * Added function silc_server_get_users_on_channel and function
59 silc_server_save_users_on_channel to the silcd/server.[ch].
61 * Removed function silc_server_command_send_users from the
64 * Do not show topic on the client library anymore. The topic is
65 sent in the command reply notify to the application and the
66 application must show the topic now.
68 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
70 * Added client searching by nickname hash into the IDENTIFY and
71 WHOIS commands in the server as they were clearly missing from
72 them. Affected file is silcd/command.c.
74 * Fixed a bug in private message receiving in the client library.
75 The remote ID was freed and it wasn't supposed, now it is
78 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
80 * Minor fix to the channel payload; allocate the data area, as it
81 needs to be of specific length.
83 * If the key agreement port is zero then the operating
84 system will define the bound port. Affected files are
85 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
87 * Added new function silc_channel_payload_decrypt into the file
88 lib/silccore/silcchannel.[ch].
90 * Moved the channel message etc, check from silc_packet_decrypt
91 to applications. The library calls now a generic
92 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
93 when the packet is either normal or special. This was done to
94 allow more wide range of checking that was not allowed when
95 the code was in library. Now applications can do virtually any
96 checks to the packet and return to the library the decision how
97 the packet should be processed. Affected files are
98 lib/silccore/silcpacket.[ch].
100 Added silc_server_packet_decrypt_check to the server and
101 silc_client_packet_decrypt_check to the client library.
103 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
104 to send with specified source and destination information.
106 * Channel message delivery between routers was broken after the
107 channel key distribution was fixed earlier. The channel key
108 was used be to distributed to other routers as well which is not
109 allowed by the protocol. Now this is fixed and channel keys
110 really are cell specific and the channel message delivery between
111 routers comply with the protocol specification.
113 * Fixed various commands in server to check also the global list
114 for the channel entry and not just the local list. The affected
115 file silcd/command.c.
117 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
119 * Added assert()s to buffer formatting and unformatting routines
120 to assert (if --enable-debug) when error occurs. Affected
121 file: lib/silcutil/silcbuffmt.c.
123 * Changed to auto-reconnect to check whether the remote host is
124 router and register the re-connect timeout if it is. It used
125 to check that whether we are normal server, but router must do
126 auto-reconnect with another router as well. Affected file
129 * Removed the [<key len>] option from CMODE command as the cipher
130 name decides the key length, nowadays. See the defined ciphers
131 from the protocol specification.
133 * Added [<hmac>] option to the CMODE command to define the HMAC
134 for the channel. Added SILC_CMODE_HMAC channel mode.
136 * Added [<hmac>] option for the JOIN command so that user can
137 select which HMAC is used to compute the MACs of the channel
140 * Added Hmac field to the Channel Message Payload. The integrity
141 of plaintext channel messages are now protected by computing
142 MAC of the message and attaching the MAC to the payload. The
143 MAC is encrypted. Now, it is clear that this causes some
144 overhead to the size of the packet but rationale for this is that
145 now the receiver can verify whether the channel message decrypted
146 correctly and also when private keys are set for the channel the
147 receiver can decrypt the packet with several keys and check from
148 the MAC which key decrypted the message correctly.
150 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
151 lib/silccrypt/silccipher.[ch].
153 * Added silc_hash_len to return the digest length into the
154 lib/silcrypt/silchash.[ch].
156 * Rewrote parts of Silc Channel Payload interface in the
157 lib/silccore/silcchannel.[ch]. The encode function now also
158 encrypts the packet and parse function decrypts it.
160 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
162 * Fixed a minor formatting bug in the SKE's key material processing.
163 It actually might have processed the keys wrong way resulting
166 * Redefined the mandatory HMAC algorithms and added new algorithms.
167 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
168 and hmac-md5 truncated to 96 bits. The mandatory is now
169 hmac-sha1-96. Rest are optional (including the one that used
170 to be mandatory). Rationale for this is that the truncated HMAC
171 length is sufficient from security point of view and can actually
172 make the attack against the HMAC harder. Also, the truncated
173 HMAC causes less overhead to the packets. See the RFC2104 for
176 * Added new [hmac] configuration section. The SKE used to use
177 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
178 is of course wrong. The official names that must be proposed in
179 the SKE are the ones defined in the protocol specification
180 (hmac-sha1-96 for example). The user can configure any hmac
181 using any hash function configured in the [hash] section. At
182 least, the mandatory must be configured.
184 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
186 * Added HMAC list to the SKE proposal list. It has now both
187 hash algorithm list and HMAC list. This makes the protocol
188 incompatible with previous versions. The SKE now seems to work
189 the way it is supposed to work, for the first time actually.
191 * Defined plain Hash algorithms to the protocol specification.
194 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
196 * Implemented support for key agreement packets into the server.
197 Added functions silc_server_key_agreement and
198 silc_server_send_key_agreement. Other than these functions,
199 server has nothing to do with this packet.
201 * Added support for private message key packets into the server.
202 Added functions silc_server_private_message_key and
203 silc_server_send_private_message_key.
207 * Changed the silc_[client|server]_protocol_ke_set_keys to be
208 called in the protocol's final callback instead in the END
209 protocol state. This makes a little more sense and in the same
210 time in client we can use the same protocol routines for normal
211 key exchange and to key agreement packet handling as well.
213 * Added to both client's and server's KE protocol context the
214 SilcSKEKeyMaterial pointer to save the key material. We will
215 bring the key material to the protocol's final callback by doing
216 this. The final callback must free the key material.
218 * Added SKE's packet_send callback into client's KE protocol
219 context so that the caller can choose what packet sending function
220 is used. This way we can use different packet sending when
221 doing normal SKE when doing key agreement packet handling (in
222 the key agreement packet handling we do not want to encrypt
225 * Implemented the responder side of the key agreement routines
226 in the client. The client can now bind to specified port and
227 accept incoming key negotiation. The key material is passed
228 to the application after the protocol is over.
230 * Implemented the processing of incoming Key Agreement packet
231 in the client. Added function silc_client_key_agreement to
234 * Implemented the intiator side of the key agreement routines
235 in the client. The client can now initiate key agreement with
236 another remote client. The key material is passed to the
237 application after the protocol is over.
239 * Created client_keyagr.c to include all the key agreement
242 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
243 SILC_TASK_CALLBACK except that it is not static.
245 * Created client_notify.c and moved the Notify packet handling
246 from the client.[ch] into that file.
248 * Created client_prvmsg.c and moved all private message and
249 private message key routines from the client.[ch] into that file.
251 * Create client_channel.c and moved all channel message and
252 channel private key routines from the client.[ch] into that file.
254 * Changed silc_client_get_client_by_id_resolve to resolve with
255 WHOIS command instead of IDENTIFY command, in the file
256 lib/silclient/idlist.c.
258 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
260 * Implemented the SKE's responder side to the Client library.
262 * When FAILURE is received to the protocol do not trust it
263 blindly. Register a timeout to wait whether the remote closes
264 the connection as it should do it, only after that process the
265 actual failure. This was changed to both client and server.
267 * Added client_internal.h to include some of the structures
268 there instead of client.h in lib/silcclient/.
270 * Added function silc_task_unregister_by_callback to unregister
271 timeouts by the callback function.
273 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
275 * Some "Incomplete WHOIS info" errors has been appearing on the
276 log files. Took away the entry->userinfo check from WHOIS
277 reply sending. The entry->userinfo is now " " if client did not
278 provide one. I thought this was fixed earlier but something
279 is wrong still. Let's see if the error still appears.
281 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
283 * Fixed a minor bug in the login when the channel key is
284 re-generated in the server. It used to generate the key in
285 wrong order and thus caused problems in the channel traffic.
287 * Fixed a minor bug in channel key distsribution after
288 KICK command. The key was not sent to the router even though
291 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
293 * Added silc_ske_process_key_material_data as generic routine
294 to process any key material as the SILC protocol dictates. The
295 function is used by the actual SKE library but can be used by
296 applications as well. This relates to the private message keys
297 and the channel private keys since they must be processed the
298 same way the normal SILC session keys. The protocol dictates
299 this. Affected files: lib/silcske/silcske.[ch].
301 Added also silc_ske_free_key_material to free the
302 SilcSKEKeyMaterial structure.
304 * Defined silc_cipher_set_key function to set the key for
305 cipher without using the object's method function. The affected
306 files: lib/silccrypt/silccipher.[ch].
308 * Implemented silc silc_client_add_private_message_key,
309 silc_client_add_private_message_key_ske,
310 silc_client_del_private_message_key,
311 silc_client_list_private_message_keys and
312 silc_client_free_private_message_keys functions in the
315 Added functions silc_client_send_private_message_key to send
316 the Private Message Key payload and silc_client_private_message_key
317 to handle incoming Private Message Key payload.
319 * Added Cipher field to the Private Message Key payload to set
320 the cipher to be used. If ignored, the default cipher defined
321 in the SILC protocol (aes-256-cbc) is used.
323 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
325 * Removed lib/silcclient/ops.h file.
327 Redefined parts of the SILC Client Library API. Created new
328 file silcapi.h that deprecates the ops.h file and defines the
329 published Client Library API. Defined also private message key
330 API and channel private key API into the file.
332 This is the file that the application must include from the
333 SILC Client Library. Other files need not be included by
334 the application anymore.
336 * Added new key_agreement client operation callback and also
337 defined the Key Agreement library API for the application.
339 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
342 is used by clients to request key negotiation between another
343 client in the SILC network. If the negotiation is started it
344 is performed using the SKE protocol. The result of the
345 negotiation, the secret key material, can be used for example
346 as private message key.
348 Implemented the Key Agreement payload into the files
349 lib/silccore/silauth.[ch].
351 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
353 * Redefined ciphers for the SILC protocol. Added some new ciphers
354 and defined the key lengths for the algorithms. Changed the
355 code accordingly. The default key length is now 256 bits.
357 * Fixed SKE key distribution function silc_ske_process_key_material
358 when the key length is more than 128 bits. The default key
359 length in SILC is now 256 bits.
361 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
362 to indicate unsupported algorithm.
364 * Renamed rijndael.c to aes.c and all functions as well.
366 * Fixed a long standing channel key setting bug in client library.
367 Weird that it has never surfaced before.
369 * Fixed bug in channel deletion. If the entire channel is removed
370 then it must also delete the references of the channel entry
371 from the client's channel list as the client's channel entry and
372 the channel's client entry share same memory.
374 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
376 * Implemented CONNECT and SHUTDOWN commands in the client.
378 * Implemented CLOSE command to the client.
380 * Added the function silc_idlist_find_server_by_name into the
381 files silcd/idlist.[ch].
383 Added the function silc_idlist_find_server_by_conn into the
384 files silcd/idlist.[ch].
386 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
388 * DIE command was renamed to SHUTDOWN. Updated the both code
391 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
392 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
394 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
397 * Added function silc_server_create_connection function to create
398 connection to remote router. My server implementation actually
399 does not allow router to connect to normal server (it expects
400 that normal server always initiates the connection to the router)
401 so the CONNECT command is only good for connecting to another
404 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
407 or some other client was kicked from the channel.
409 Implemented the handling of the notify type to both client
412 Implemented silc_server_send_notify_kicked to send the KICKED
413 notify. It is used to send it to the server's primary router.
415 * Implemented the KICK command into server and client.
417 * Added `query' argument to the silc_idlist_get_client function
418 to indicate whether to query the client from server or not if
421 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
422 to indicate that the client is not channel founder.
426 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
428 * Removed the rng context from SilcPacketContext structure and
429 changed that the packet routine uses the Global RNG API.
431 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
433 * Added support for quit message that client can "leave" on the
434 channel when it quits the SILC. It is ditributed inside the
435 SILC_NOTIFY_TYPE_SIGNOFF notify type.
437 Added silc_server_free_client_data that will take the
438 signoff message as argument.
440 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
442 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
444 * Updated parts of the protocol specification to keep it up
447 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
449 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
450 payloads in one packet.
452 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
453 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
454 use now the new List flag.
456 * Also deprecated the following packet types: REPLACE_ID,
457 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
459 * Added list support for Notify packet in server.
461 * Added silc_server_send_notify_channel_change to send the
462 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
463 the silc_server_send_replace_id.
465 * Added silc_server_send_notify_nick_change to send the
466 NICK_CHANGE notify type. Deprecates the function
467 silc_server_send_replace_id.
469 * Added silc_server_send_notify_join to send the JOIN notify type.
470 Deprecates the function silc_server_send_new_channel_user.
472 * Added silc_server_send_notify_leave to send LEAVE notify type.
473 Deprecates the function silc_server_send_remove_channel_user.
475 * Added silc_server_send_notify_cmode and
476 silc_server_send_notify_cumode to send CMODE and CUMODE notify
477 types. Deprecates the silc_server_send_set_mode function.
479 * Added SERVER_SIGNOFF notify type to indicate that server has
480 quit. This means that all clients on the channel from that
481 server will drop. This can be also used when netsplit happens.
483 Deprecated REMOVE_ID packet type since it is not needed anymore
486 Added silc_server_send_notify_server_signoff to send the
487 SERVER_SIGNOFF notify type. Deprecates the function
488 silc_server_send_remove_id.
490 Added also silc_server_send_notify_signoff to send the
493 * Employed the PKCS #1. It is the mandatory way to do RSA in the
494 SILC protocol from this day on. Changed the protocol
495 specification as well.
497 * Added silc_server_send_notify_topic_set to send TOPIC_SET
498 notify type. It is used between routers to notify about
499 topic changes on a channel.
501 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
504 * Partly updated the protocol specification to comply with the
505 changes now made. It is still though a bit outdated.
507 * The JOIN notify type now takes one extra argument <Channel ID>.
508 The packet used to be destined to the channel but now the
509 JOIN type may be sent as list thus it is impossible to
510 destine it to any specific channel. By adding this argument
511 it is again possible.
513 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
515 * Added CREDITS file. The CHANGES and CREDITS file will appear
516 in the distribution as well.
518 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
520 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
521 types in the server's silcd/packet_receive.c.
523 * Implemented CMODE and CUMODE to work in router environment.
525 * Fixed minor encoding and decoding buglet from the
526 lib/silccore/silcmode.c.
528 * Fixed buffer overflow from lib/silcclient/command.c in USERS
531 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
533 * Changed all SilcConfigServer* and silc_config_server* to
534 SilcServerConfig* and silc_server_config*, respectively.
537 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
539 * Associated the ID (client or server ID) to the Authentication
540 Payload to avoid any possibility of forging. Updated the
541 protocol specification and the code accordingly.
543 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
545 * The RSA key length is now save to the RsaKey context in the
546 key generation process in lib/silccrypt/rsa.c. The key length
547 is now used to figure out the maximum size of the block allowed
548 to be encrypted/signed.
550 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
551 is equivalent to the silc_mp_mp2bin but does not allocate any
554 * Changed silc_mp_mp2bin API to take length argument. If it is
555 non-zero then the buffer is allocated that large. If zero, then
556 the size is approximated using silc_mp_sizeinbase, which however
559 * Created Global RNG API which is global RNG that application can
560 initialize. After initializing, any routine anywhere in the
561 code (including library) can use RNG without allocating a new
562 RNG object. This was done to allow this sort of use of the
563 RNG in code that has no chance to allocate RNG object. All
564 applications currently allocate this and many routines in the
565 library use this. Affected file lib/silccrypt/silcrng.[ch].
567 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
568 it to use the Global RNG API.
570 * Defined Authentication Payload into protocol specification that
571 is used during SILC session to authenticate entities. It is
572 used for example by client to authenticate itself to the server
573 to obtain server operator privileges.
575 Implemented this payload into the lib/silccore/silcauth.[ch].
576 Implemented also routines for public key based authentication
577 as the new protocol specification dictates.
579 Moved definitions of different authentication methods from
580 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
582 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
583 silc_pkcs_verify and silc_pkcs_sign_with_hash and
584 silc_pkcs_verify_with_hash functions into the file
585 lib/silccrypt/silcpkcs.[ch].
587 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
589 * The client entry's userinfo pointer must be always valid.
590 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
591 will fail since it requires the userinfo. Now, the userinfo
592 is allocated as "" if actual userinfo does not exist. Actually,
593 it must exist and it is totally Ok to drop client connections
594 that does not announce the userinfo. However, we will make
595 this workaround for now.
597 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
598 to return the remote port by socket.
600 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
602 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
603 SILC_SERVER_PENDING_EXEC and added an new macro
604 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
605 data or when error occurs while processing the pending command.
607 Added new argument `destructor' into silc_server_command_pending
608 and to the SilcServerCommandPending object. This destructor is
609 now called after calling the pending callback or if error occurs
610 immediately. If error occurs the actual pending callback won't
611 be called at all - only the destructor. The destructor may be
612 NULL if destructor is not needed.
614 All this applies for client library code as well. Similar
615 changes were made there as well for the pending commands.
617 In the client, the application must now allocate the
618 SilcClientCommandContext with the silc_client_command_alloc
621 * Added reference counter to the SilcServerCommandContext. Added
622 function silc_server_command_alloc and silc_server_command_dup
625 Same type of functions added to the client library for the same
628 * Removed the cmd_ident from IDListData away since it is now
629 global for all connections. It is the command identifier used
630 in command sending and with pending commands. The affected file
633 * Added reference counter to the SilcSocketConnection objecet to
634 indicate the usage count of the object. The object won't be
635 freed untill the reference counter hits zero. Currently only
636 server uses this, and client ignores it. The client must be
637 set to use this too later. The affected files are
638 lib/silccore/silcsockconn.[ch]. Added also the function
639 silc_socket_dup to increase the reference counter.
641 This was mainly added because it is possible that the socket
642 is removed underneath of pending command or other async
643 operation. Now it won't be free'd and proper DISCONNECTING
644 flags, etc. can be set to avoid sending data to connection that
645 is not valid anymore.
647 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
648 the connection. After that it sets SILC_SET_DISCONNECTED.
649 It is, however, possible that the socket data is not still freed.
650 The silc_server_packet_process now checks that data is not
651 read or written to connection that is DISCONNECTED. The socket
652 get's freed when the reference counter hits zero.
654 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
656 * Changed the client operation API: channel_message operation's
657 `sender' is now the client entry of the sender, not the nickname
658 and the `channel' is the channel entry, not the channel name.
660 In the private_message operation the `sender' is now also the
661 client entry of the sender not the nickname.
663 Affected file is lib/silcclient/ops.h and all applications
664 using the client operations.
666 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
668 * Moved the calling of ops->connect() from connect_to_server_final
669 into receive_new_id functin since that is the point when the
670 client is actually allowed to send traffic to network. The
671 affected file is lib/silcclient/client.c.
673 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
675 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
676 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
677 (if needs broadcasting) instead of broadcasting the packets one
678 by one which would make a burst in the network traffic.
680 * Added `broadcast' argument to the functions in silcd/server.[ch]
681 silc_server_create_new_channel[_with_id] to indicate whether
682 to send New Channel packet to primary router.
684 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
686 * Added new function into the silcd/server.[ch] files:
687 silc_server_create_new_channel_with_id to create new channel with
688 already existing Channel ID.
690 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
691 lib/silccore/silcpacket.h. This packet is used t send list of
692 Set Mode payloads inside one packet. Server uses this to set
693 the modes for the channels and clients on those channels, that it
694 announced to the router when it connected to it. The protocol
695 specification has been updated accordingly.
697 * The silc_server_new_channel did not handle the packet coming
698 from normal server as it normally does not send that. However,
699 when it announces its channels it does send it. Implemented
700 the support for that.
702 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
703 into the file lib/silccore/id.h.
705 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
707 * Fixed memory leaks in the functions silc_idlist_del_client,
708 silc_idlist_del_channel and silc_idlist_del_server in the file
709 silcd/idlist.c. All of those leaked like a sieve.
711 * Fixed some small memory leaks in the client's function
712 silc_client_notify_by_server.
714 * Added functions into silcd/server.c: silc_server_announce_clients,
715 silc_server_announce_channels and silc_server_announce_server.
716 These functions are used by normal and router server to announce
717 to its primary router about clients, channels and servers (when
718 router) that we own. This is done after we've connected to the
721 These functions effectively implements the following packet types:
722 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
723 and SILC_PACKET_NEW_ID_LIST.
725 * Added new functions into the silcd/packet_receive.[ch]:
726 silc_server_new_id_list, silc_server_new_channel_list and
727 silc_server_new_channel_user_list to handle the incoming
728 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
730 * Added support of changing Channel ID in the function
731 silc_server_replace_id. If the server that announces a channel
732 to the router already exists in the router (with same name but
733 with different Channel ID), router is responsible to send
734 Replace ID packet to the server and force the server to change
735 the Channel ID to the one router has.
737 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
738 client that the Channel ID has been changed by the router. The
739 normal server sends this to the client. Client must start using
740 the new Channel ID as the channel's ID.
742 Implemented handling of this new type into lib/silcclient/client.c
743 into the function silc_client_notify_by_server.
745 * Added new function silc_idlist_replace_channel_id into the files
746 silcd/idlist.[ch] to replace the Channel ID.
748 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
750 * Call silc_server_command_identify_check always when processing
751 the IDENTIFY command in silcd/command.c
753 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
755 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
756 send keepalive packets. The packet can be sent by clients,
759 Added function silc_socket_set_heartbeat into the file
760 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
761 If not set, the heartbeat is not performed. The actual
762 heartbeat is implemented in the low level socket connection
763 library. However, application is responsible of actually
766 Added silc_server_send_heartbeat to send the actual heartbeat
767 packet into silcd/packet_send.[ch]. Server now performs
768 keepalive with all connections.
770 * Added silc_task_get_first function into lib/silcutil/silctask.c
771 to return the timeout task with shortest timeout. There was a bug
772 in task unregistration that caused problems. TODO has been
773 updated to include that task system must be rewritten.
775 * The client library will now resolve the client information when
776 receiving JOIN notify from server for client that we know but
777 have incomplete information.
779 * Rewrote parts of silc_server_remove_from_channels and
780 silc_server_remove_from_one_channel as they did not remove the
781 channel in some circumstances even though they should've.
783 * Encryption problem encountered in server:
785 The LEAVE command used to send the Channel Key packet to the
786 router immediately after generating it. However, the code
787 had earlier sent Remove Channel user packet but not immediately,
788 ie. it was put to queue. The order of packets in the router
789 was that Channel Key packet was first and Remove Channel User
790 packet was second, even though they were encrypted in the
791 reverse order. For this reason, MAC check failed. Now, this
792 is fixed by not sending the Channel Key packet immediately but
793 putting it to queue. However, this is more fundamental problem:
794 packets that are in queue should actually not be encrypted
795 because packets that are sent immediately gets encrypted
796 actually with wrong IV (and thus MAC check fails). So, packets
797 that are in queue should be encrypted when they are sent to
798 the wire and not when they put to the queue.
800 However, the problem is that the current system has not been
801 designed to work that way. Instead, the packet is encrypted
802 as soon as possible and left to the queue. The queue is then
803 just purged into wire. There won't be any fixes for this
804 any time soon. So, the current semantic for packet sending
807 o If you send packet to remote host and do not force the send
808 (the packet will be in queue) then all subsequent packets to the
809 same remote host must also be put to the queue. Only after the
810 queue has been purged is it safe again to force the packet
813 o If you send all packets immediately then it safe to send
814 any of subsequent packets through the queue, however, after
815 the first packet is put to queue then any subsequent packets
816 must also be put to the queue.
818 Follow these rules and everything works fine.
820 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
822 * Added new function silc_server_remove_clients_by_server to
823 remove all client entries from ID list when the server connection
824 is lost. In this case it is also important to invalidate all
825 client entires as they hold the invalid server entry. This
826 fixes fatal bug when server has lost connection and will reconnect
829 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
831 * Made some sanity checks to silc_server_daemonise like to check
832 whether the requested user and group actually exists.
834 * Added sanity check to SKE's silc_ske_responder_finish to check
835 that the public and private key actually is valid.
837 * Invalidate the client's nickname when receiving Replace ID
838 packet and the Client ID is being replaced. This means that the
839 server will query the nickname if someone needs it (client)
842 * Sort the ID Cache in client library when the ID Cache data
843 has changed (needs sorting).
845 * Do not allow for SILC client to create several connections to
846 several servers. The client does not support windows right now
847 and generating multiple connections causes weird behaviour.
849 Irssi-silc client does support windows and can handle several
850 connections without problems, see: www.irssi.org and SILC plugin.
852 * Fixed some places where client was added to the IDList. The
853 rule of thumb is following (in order to get everything right):
854 If the client is directly connected local client then the
855 `connection' argument must be set and `router' argument must be
856 NULL to silc_idlist_add_client function. If the client is not
857 directly connected client then the `router' argument must
858 bet set and the `connection' argument must be NULL to the
859 silc_idlist_add_client function.
861 * The funtion silc_server_packet_send_local_channel actually did
862 not check whether the client was locally connected or not. It
863 does that now. Fixed a bug related to LEAVE command.
865 * Fixed Remove Channel User payload parsing bug in server's
866 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
868 * The server's silc_server_save_channel_key now checks also the
869 global ID list for the channel as it might not be in the local
870 list. Fixed a bug related to LEAVE command.
872 * Is this the end of the [<unknown>] buglet that has been lurking
873 around for a long time? A little for loop fix in server's
874 silc_server_command_whois_parse that is used by both IDENTIFY
875 and WHOIS command. At least, this was a clear bug and a cause
876 of one type of [<unknown>] buglet.
878 * WHOIS and IDENTIFY commands call the function
879 silc_server_command_[whois/identify]_check function even if
880 we are not router server.
882 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
884 * Added --with-gmp configuration option. If set the GMP
885 is always compiled in the SILC source tree. If not set then
886 it is checked whether the system has the GMP3 installed. If
887 it has then the GMP won't be compiled (the system's headers
888 and library is used), if it doesn't have it then the GMP is
889 compiled in the SILC source tree.
891 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
893 * Changed RSA private exponent generation to what PKCS #1
894 suggests. We try to find the smallest possible d by doing
895 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
896 not security fix but optimization.
898 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
900 * Added new config entry [Identity] to fork the server and run
901 it as specific user and group. A patch from Bostik.
903 * Imported Dotconf configuration library into lib/dotconf.
904 This will be used to create the SILC configuration files later.
905 It will appear in the distsribution after this commit.
907 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
909 * A big code auditing weekend happening. Auditing code for
910 obvious mistakes, bugs and errors. Also, removing any code
913 Removed files for being obsolete:
915 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
916 inline in the file lib/silcutil/silcbuffer.h)
918 o lib/silcutil/silcbufutil.c (the header has inline versions)
920 Changed code to fix possible error conditions:
922 o The buffer formatting routines now check that the destination
923 buffer really has enough space to add the data. This applies for
924 both buffer formatting and unformatting
925 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
926 unformatting was changed to accomodate following rules:
927 XXX_*STRING_ALLOC will allocate space for the data into the pointer
928 sent to the function while XXX_*STRING will not allocate or copy
929 the data into the buffer. Instead it sets the pointer from the
930 buffer into the pointer sent as argument (XXX_*STRING used to
931 require that the pointer must be allocated already). This change
932 makes this whole thing a bit more consistent and more optimized
933 (note that the data returned in the unformatting with XXX_*STRING
934 must not be freed now). The routines return now -1 on error.
936 o Tried to find all code that use buffer_format and buffer_unformat
937 and added return value checking to prevent formatting and
938 especially unformatting errors and possible subsequent fatal
941 o Changed ske->x and ske->KEY to mallocated pointers in
942 lib/silcske/silcske.h. Fixed possible data and memory leak.
944 o Added return value checking to all *_parse* functions. Fixed
945 many memory leaks as well.
947 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
948 so that buffer overflows would not happen. All code now also
949 checks the return value as it can fail.
951 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
953 * Added reconnection support to server if the normal server looses
954 its connection to the router (for example if router is rebooted).
955 The server performs normal reconnection strategy implemented
956 to the server. Affected file silcd/server.c.
958 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
960 * Added new packet type SILC_PACKET_SET_MODE that is used to
961 distribute the information about changed modes (for clients,
962 channels and clients channel modes) to all routers in the
963 network. Updated the protocol specification accordingly.
965 Added functions into silcd/packet_send.c and
966 silcd/packet_receive.c: silc_server_send_set_mode,
967 silc_server_set_mode.
969 Added new files silcmode.[ch] into lib/silccore that implements
970 the encoding and decoding of Set Mode Payload. Added new type
971 SilcSetModePayload. Moved the definitions of different modes
972 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
974 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
976 * Oops, a little mistake in server's connection authentication
977 protocol. The protocol is not ended with FAILURE but with
978 SUCCESS if the authentication is Ok. :) Affected file is
981 * Implemented NICK_CHANGE notify handling in server in the file
982 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
983 the local clients on the channel. After the changing nickname
984 in router environment snhould work and the [<unknown>] nickname
985 should appear no more.
987 The silc_server_replace_id function that receives the Replace ID
988 payload now sends the NICK_CHANGE notify type also in the file
989 silcd/packet_receive.c
991 * Changed WHOIS and IDENTIFY command to support the maximum amount
992 of arguments defined in protocol specs (3328 arguments). This
993 fixed a bug that caused problems when there were more than three
996 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
998 * Added extra parameter, command identifier, to the
999 silc_client_send_command so that explicit command identifier
1002 Changed that ID list routines uses specific command identifier
1003 when sending WHOIS/IDENTIFY requests to the server so that they
1004 can be identified when the reply comes back.
1006 Affected files lib/silcclient/command.[ch],
1007 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1009 * Added `sender' argument to silc_server_packet_send_to_channel
1010 to indicaet the sender who originally sent the packet to us
1011 that we are now re-sending. Ignored if NULL. Affected file
1012 silcd/packet_send.[ch].
1014 * Added some server statistics support in silcd/server_internal.h
1015 SilcServerStatistics structure and around the server code. Also
1016 send some nice statistics information when client is connecting
1019 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1021 * Fixed channel ID decoding in server's JOIN command reply in
1022 silcd/command_reply.c
1024 * Fixed braodcasting of replace ID payload to not to send it if
1025 we are standalone server in silcd/packet_receive.c.
1027 * Fixed all channel message sending routines to not to send
1028 packets to clients that has router set, since they are routed
1029 separately in the same function earlier. Affects file
1030 silcd/packet_send.c and all channel packet sending functions.
1032 * In USERS reply, res_argv[i] are not allocated, the table
1033 is allocated. Thus changed that free the table, not its
1036 * In server's whois_check and identify_check if the client is
1037 locally connected do not send any WHOIS commands - they are not
1040 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1042 * Fixed some minor bugs in client when sending WHOIS command. The
1043 arguments was in wrong order.
1045 * Removed statis function add_to_channel from server in
1046 silcd/command.c that was previously used with the joining but
1049 * Tested USERS command in router environment successfully with two
1050 routers, two servers and two clients.
1052 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1054 * Reorganized the USERS command and command reply in client library
1055 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1056 When the command is given by user we register a pending command
1057 callback that will reprocess the command after the reply has been
1058 received from the server. When reprocessing the packet we then
1059 display the information. Thus, the USERS information is displayed
1060 now in the command callback instead of in the command reply
1061 callback. The processing of the command is same as previously
1062 when server has sent the command reply in the JOINing process.
1064 * Added to USERS command in silcd/command_reply.c to join the client,
1065 we didn't use to know about, to the channel after we've created
1066 a client entry for it. Also, for clienet we did know already still
1067 check whether it is on the channel or not and add it if not.
1069 * Removed silc_server_command_join_notify as the function and its
1072 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1074 * Changed the client's pending command handling to the same as the
1075 server's pending command handling. It is also now possible to
1076 execute command reply functions from other command reply
1077 function as the function callbacks for commands and command
1078 replies are one and same. The pending commands are not static
1079 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1080 in client connection context. Thus, pending commands are server
1081 connection specific as it is convenient.
1083 Changed the function silc_client_command_pending and
1084 silc_client_command_pending_del and added new function
1085 silc_client_command_pending_check. Removed the
1086 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1089 * Added cmd_ident, current command identifier, to the client
1090 connection context in lib/silcclient/client.h to keep track on
1091 command identifiers used in command sending. Client's command reply
1092 function handling now supports the mandatory command identifiers.
1094 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1095 funtions in client to fully support pending command callbacks.
1097 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1098 as one of the arguments to the application in the command reply
1101 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1102 before first releasing SILC but came back. Now it is removed again
1103 and should come back nomore. The FORWARDED flag was used only
1104 by the JOINing procedure by forwarding the command packet to router.
1105 Now, the JOINing procedure has been changed to more generic (due
1106 to various router environment issues) and FORWARDED is not needed
1107 anymore for anything. The protocol specification is yet to be
1110 Now, removed silc_server_packet_forward from server and the flag
1111 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1113 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1115 * Renamed NAMES command to USERS command. The NAMES was named that
1116 due to historical reasons. Now it is renamed. Also, rewrote
1117 parts of the USERS command. The nickname list is not sent anymore
1118 by the server. Only Client ID and mode lists are sent in the USERS
1119 command. Changed this also to the protocol specification.
1121 The client now resolves the names and stuff after it receives
1122 the USERS list from the server when joining to the channel.
1124 * WHOIS and IDENTIFY commands has been changed to support multiple
1125 Client ID's per command. One can now search for multiple users
1126 in the network by sending only one WHOIS or IDENTIFY command.
1127 Changed the code and the protocol specifications.
1129 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1130 uses silc_server_command_whois_parse to parse the request. */
1132 * If normal server, do not parse the WHOIS and IDENTIFY requests
1133 before sending it to the router. Saves some time.
1135 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Fixed JOIN command on client library. Wrong number of arguments
1138 used to crash the client.
1140 * Added silc_server_channel_has_global function to check whether
1141 channel has global users or not.
1143 * Added silc_server_channel_has_local function to check whether channel
1144 has locally connected clients on the channel.
1146 * The silc_server_remove_from_one_channel now checks whether the
1147 channel has global users or not after given client was removed from
1148 the channel. It also checks whether the channel has local clients
1149 on the channel anymore. If it does not have then the channel entry
1150 is removed as it is not needed anymore.
1152 * The silc_server_notify now checks on JOIN notify whether the joining
1153 client is one of locally connected or global. If it is global then
1154 the channel has now global users on the channel and that is marked
1155 to the channel entry. Also, it now saves the global client to
1156 global list who is joining and JOINs it to the channel. This is
1157 for normal server, that is.
1159 Changed silc_server_send_notify_on_channel,
1160 silc_server_packet_relay_to_channel and
1161 silc_server_packet_send_to_channel check if we are normal server
1162 and client has router set (ie. global client) do not send the
1163 message to that client, as it is already routed to our router.
1165 * Implemented LEAVE notify type handling in silc_server_notify
1168 * Tested LEAVE command in router environment successfully. Tested
1169 with two routers, two servers and two clients.
1173 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1175 * Implemented SIGNOFF notify type handling in silc_server_notify
1178 * silc_server_remove_id now removes the client entry from all channels
1179 it has joined and thusly sends SIGNOFF notify type.
1181 * Rewrote the NAMES list generation in server by removing two excess
1182 loops. The lists are created now inside one loop.
1184 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1186 * silc_server_remove_channel_user checks now also global list
1187 for channel and client.
1189 * silc_server_new_channel_user checks now both local and global
1190 list for channel and client. Fixed a bug in client id decoding.
1191 Used to decode wrong buffer.
1193 * silc_server_channel_message checks now both local and global
1194 list for channel entry.
1196 * Tested channel joining (hence JOIN) in router environment
1197 successfully. Tested with two routers, two servers and two
1200 * Tested channel message sending in router environment successfully.
1202 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1204 * Added silc_server_save_channel_key into server.[ch] to save the
1205 received channel key in Channel Key payload processing. It is
1206 also used in JOIN command reply handling.
1208 Equivalent function silc_client_save_channel_key added into
1209 client.[ch] into client library.
1211 * Changed JOIN command reply to send information whether the channel
1212 was created or not (is existing already) and the channel key
1213 payload. Changed protocol specs accordingly.
1215 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1216 the request was sent by ID and not by nickname. Crashed on
1219 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1221 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1222 now correctly save the received data.
1224 * silc_server_free_sock_user_data now notifies routers in the
1225 network about entities leaving the network.
1227 At the same time implemented functions silc_server_remove_id
1228 and silc_server_send_remove_id to receive and send REMOVE_ID
1229 packets. The packet is used to notify routers in the network
1230 about leaving entities. The ID removed will become invalid in
1233 * Added function silc_idlist_del_server into server. Removes and
1234 free's server entry from ID list.
1236 * silc_server_private_message function now checks, if we are router,
1237 that the destination ID really is valid ID, naturally.
1239 * In router when NEW_ID packet is received (for new client) the
1240 hash of the Client ID is saved in the ID Cache but the
1241 client->nickname is set to NULL, instead of putting the hash
1244 IDENTIFY command now also checks that client->nickname must be
1245 valid. If it is not if will request the data from the server who
1246 owns the client. Added new function
1247 silc_server_command_identify_check.
1249 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1250 to set the command to already allocated Command Payload.
1252 * Tested private message sending in router environment with two
1253 routers, two servers and two clients. Fixed minor bugs and now
1256 * Fixed segfault from client's NAMES command. Used to crash if
1259 * Forwarded packets must not be routed even if it is not destined
1260 to the receiver. Changed server code comply with this.
1262 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1264 * Added `require_reverse_mapping' boolean value to ServerParams
1265 structure. If TRUE (not default) the server will require that
1266 the connecting host has fully qualified domain name.
1268 If the reverse mapping is not required and hostname could not be
1269 found the IP address is used as hostname.
1271 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1273 * Implemented version string checking to both client and server.
1274 The check is incomplete currently due to the abnormal version
1275 strings used in development version of SILC.
1277 * Changed all command functions in server to use the new
1280 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1282 * Changed char *data to unsigned char *data in ID Cache system to
1283 support binary data as ID Cache data. Changed code to support
1284 binary data in lib/silccore/idcache.c.
1286 * Renamed silc_server_packet_relay_command_reply to
1287 silc_server_command_reply as it is normal packet receiving
1288 function. Rewrote the function to accept command replys for
1289 servers and not only for clients.
1291 * Mark remote router always as registered server if we are connecting
1292 to it. Otherwise, commands sent by the router to us are ignored.
1294 * All ID List find routines now returns the ID Cache Entry pointer
1295 as well if requested.
1297 * WHOIS command works now in router environment, tested with two
1298 routers, two servers and two clients.
1300 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1301 in router environment (as it is almost equivalent to WHOIS) but
1302 hasn't been tested thoroughly. Added new functions:
1304 silc_server_command_identify_parse
1305 silc_server_command_identify_send_reply
1306 silc_server_command_identify_from_client
1307 silc_server_command_identify_from_server
1309 * Disabled route cache adding because adding two different ID's with
1310 same IP replaces the old cache entry thus giving wrong route.
1311 The entry->router->connection is always the fastest route anyway
1312 so route cache may not be needed. Of course, new routes maybe
1313 established after receiving the ID when the entry->router->connection
1314 might not be anymore the most optimal.
1316 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1318 * Add route cache for received ID for fast routing.
1320 * Added silc_server_packet_route to route received packet on router
1321 that is not destined to us.
1323 * Renamed silc_server_get_route to silc_server_route_get.
1325 * Added id_string and id_string_len fields into SilcServer to
1326 include encoded ServerID for fast comparing without excess
1327 encoding of the ID's.
1329 * Cleaned up WHOIS command on server side. Added following static
1332 silc_server_command_whois_parse
1333 silc_server_command_whois_check
1334 silc_server_command_whois_send_reply
1335 silc_server_command_whois_from_client
1336 silc_server_command_whois_from_server
1338 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1339 arguments in command replies. All command functions should be
1340 updated to use this macro.
1342 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1344 * Minor typo fixes on command reply handling on server.
1346 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1348 * Added silc_server_command_add_to_channel internal routine to add
1349 the client to the channel after router has created the channel and
1350 sent command reply to the server.
1352 * Added generic silc_server_send_command to send any command from
1355 * Use static buffer with ID rendering instead of duplicating data.
1357 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1359 * Fixed a channel user mode bug when joining to a channel server gave
1360 everybody channel founder rights, oops.
1362 * We mark ourselves as the router of the incoming server connection
1363 if we are router ourselves. This way we can check in some packet
1364 sending functions whether it is locally connected server. For
1365 incoming router connections we put NULL.
1367 * For router sending packets locally means now always sending the
1368 packet cell wide; to local clients and local servers. For normal
1369 server sending packet locally means sending it to only local
1372 * Fixed the JOIN command to really work in router environment. If the
1373 channel is created it is always created by the router. Router is
1374 also responsible of making the initial joining to the channel,
1375 sending JOIN notify to the sending server and distributing
1376 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1377 does not exist server doesn't do anything else but forward the
1378 command to the router which performs everything.
1380 * Added silc_server_send_channel_key function to send the Channel Key
1383 * Added silc_server_create_channel_key to create new channel key. The
1384 channel key is now re-generated everytime someone joins or leaves
1385 a channel, as protocol dictates. Note: channel->key_len is the
1388 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1390 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1391 packet_receive.[ch] to separate packet sending and receiving
1392 routines. The server.[ch] now includes everything else including
1393 actual packet processing (writing and reading data) and other
1396 Renamed silc_server_private_message_send_internal to
1397 silc_server_send_private_message. The routine is still though
1398 used only to relay private messages as server does not send
1399 private messages itself.
1401 Renamed silc_server_new_channel to silc_server_create_new_channel
1402 and added new function sicl_server_new_channel that handles the
1403 incoming New Channel packet. Added also new sending function
1404 silc_server_send_new_channel to send New Channel Payload.
1406 * Added new function silc_server_notify to process incoming notify
1407 packet to the server/router. Server may then relay the notify
1408 to clients if needed.
1410 * Added new function silc_server_new_channel_user to process incoming
1411 New Channel User packet. Router will redistribute the packet and
1412 send JOIN notify to its local clients and locally connected servers
1413 if needed. Normal server will send JOIN notify to its local client
1414 on same channel when received this packet. Added also corresponding
1415 sending function silc_server_send_new_channel_user to sent the
1418 * Added boolean route argument to send_notif_to_channel and
1419 packet_send_to_channel functions to attempt to route the packet
1420 if it is TRUE and send only locally if it is FALSE.
1422 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1424 * silc_server_replace_id now broadcasts the received replace ID
1425 packet if it is not broadcast packet already. The router must
1426 broadcast to inform other routers about changed ID.
1428 * Added backpointer to server's router into SilcServer context in
1429 silcd/server_internal.h.
1431 * Fixed silc_server_packet_broadcast to send correct broadcast
1434 * The channel key is now distributed to the local client as soon
1435 as it is received from the router (in router environment) so that
1436 no other packet may be sent for the channel until client has
1439 * silc_server_remove_channel_user now broadcasts the received
1440 Remove Channel User packet if it is not broadcast packet already.
1441 The router must broadcast to inform other routers about removed
1444 * Added users field into SilcPacketContext that is a reference count
1445 of the context. One can increase the reference count by calling
1446 silc_packet_context_dup which is now changed to just increase the
1447 reference count instead of duplicating the data. The reference
1448 count is decresed by calling silc_packet_context_free that will
1449 free the data after the reference count hits zero.
1451 For now on the packet context and everything allocated into it
1452 (including the raw packet from network) must be freed by calling
1453 the new silc_packet_context_free function. Added also new function
1454 silc_packet_context_alloc that must be used now to allocate the
1455 context. This also means that if a routine is asynchronous from
1456 silc_[client/server]_packet_parse_type the packet context must
1457 be duplicated by calling silc_packet_context_dup. Otherwise it
1458 gets free'd after silc_[client/server]_packet_parse_type returns.
1459 Also, one must remember that if packet is duplicated then its
1460 reference count must be decresed by calling the free function as
1461 many times as it was duplicated.
1463 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1464 from both client and server.
1466 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1468 * Made joining to a channel working in router environment.
1470 * Cleaned up JOIN command on server side and create function
1471 silc_server_command_join_channel internal routine to make the
1474 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1476 * Changed silc_command_pending list to SilcDList. Also, added
1477 `ident' field to SilcServerCommandPending structure to identify
1478 the reply and to call correct callback.
1480 Added silc_server_command_pending_check function to replace the
1481 corresnponding macro. The silc_command_pending list is not
1484 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1485 to set identifier to previously allocated Command Payload. It
1486 is used to set identifier for command when resending Command
1489 * Added silc_command_payload_encode_payload to encode Command
1490 Payload buffer from SilcCommandPayload structure.
1492 * Added silc_argument_payload_encode_payload to encode Argument
1493 payload buffer from SilcArgumentPayload structure.
1495 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1497 * Changed WHOIS command to support router connection on server side.
1498 The whois request is always sent to router unless the server is
1499 standalone server. After server has received the reply from the
1500 router will it send the reply to the client.
1502 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1503 broadcast received broadcast packet. The function is used only
1504 by router. The broadcast packet is always sent to the router's
1507 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1508 render given ID to printable string, for log files for example.
1510 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1512 * Made basic router to router connections working. At least they
1513 can now connect to each other but nothing really works the way
1514 they are supposed - yet.
1516 * Added new initiator token to RouterConnection configuration
1517 file in silcd/serverconfig.[ch]. It is used to tell whether we
1518 are the initiator to the remote router or whether we'll expect
1519 the other end to connect.
1521 * Moved registering of listener task to silc_server_init, hence
1522 the server starts listenning as soon as it is run, even if it
1523 does not have connections to other routers. Let's see how well
1526 * Changed default connection retry timeouts for more suitable in
1529 * Removed cipher and such arguments from silc_idlist_add_client
1530 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1531 Added new function silc_idlist_add_data to add the keys and stuff
1534 * Added SilcIDListData structure and added it to SilcClientEntry
1535 and SilcServerEntry as their first field in the structure. This
1536 way we can explicitly cast the ID entries to the SilcIDListData
1537 structure and get common data for the entries. In past, we had
1538 to first check what type of connection it is and then cast it to
1539 correct ID entry type. Now, we can directly cast the opaque
1540 pointer to the SilcIDListData (no matter what ID entry it actually
1541 is) and get the data needed.
1543 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1545 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1546 in some circumstances even if threre were timeout tasks, though not
1547 IO tasks, but tasks anyway. Now fixed.
1549 * Defined SilcServerConnection structure to hold connection specific
1550 stuff about directly connected servers and routers. The definition
1551 is currently in silcd/server_internal.h. I thought about having
1552 a bit more important role fro this struct but for now it is used
1553 only when connecting to other server (or router actually).
1555 * Added connecting retry support in server when connecting to
1556 router(s). The retry feature implement exponential backoff
1557 algorithm. Also, added SilcServerParams structure to hold default
1558 parameters for server. For now, it include these retry settings
1559 and are hard coded. After server is moded to be as Silc Server
1560 Library this structure will be more important.
1562 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1564 * Changed client librarys channel->clients table to SilcList and
1565 changed code accordingly.
1567 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1569 * Changed client's channel table to SilcList and changed code
1570 accordingly. Also changed SilcChannelClientEntry to include back-
1571 pointer to the channel so that client entry can use that structure
1572 as list as well and we have fast cross-reference to the channel.
1573 This change dramatically decreased the complexity of channel
1574 handling with client entry and vice versa (removed one extra
1575 loop when searching for channel entry from many functions).
1577 * Changed server->sim from table to SilcDList and changed code
1580 * NAMES command can now be used from user interface. It will show
1581 the user list on the channel, neatly.
1583 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1584 Code now saves realname of the user if it becomes available.
1586 * Renamed configure.in to configure.in.pre and made ./prepare
1587 script to automatically add correct version string to
1588 configure.in which it creates from configure.in.pre.
1590 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1592 * NAMES command reply now shows users mode with the nickname when
1595 * Moved silc_client_ch[u]mode[_char] functions from
1596 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1597 place sucks, they are utility functions and should be in some
1600 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1602 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1605 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1609 * Added TRQ (efficient deque and list library) into lib/trq. This is
1610 a very good list library that is currently used in the SILC. Defined
1611 SilcList API over the library because I didn't like the API very
1612 much. See lib/trq/silclist.h for the API and examples of how to
1613 use the API. Fixed various places in the code to use the new
1614 SilcList API. The SilcList is meant for lists that has a structure
1615 already defined as a list. It is not suitable to add just some
1616 context to the list (in TRQ, the context is the list actually).
1618 So, I defined SilcDList that can be used for the purpose where
1619 predefined list structure does not exit. This can be used as
1620 such list. Now some context just can be added to the SilcDList.
1621 Currently this list is not used in the SILC just yet, though there
1622 are a lot places where this can replace dynamically allocated
1623 tables and I will fix these places, later, to use SilcDList.
1624 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1625 and use TRQ internally).
1627 Also fixed some annoying warning messages that the original TRQ
1628 code generated. Also minor changes to TRQ's Makefile.in.
1630 * Added support for querying by Client ID to both WHOIS and
1631 IDENTIFY commands into server, as required by the protocol.
1633 * Removed method function pointers from SilcBuffer structure. They
1634 weren't used to anything and just increased the context size for
1635 no good reason. This change also made silc_buffer_alloc and
1636 silc_buffer_free functions inline functions.
1638 * Disabled command flooding detection support until it's fixed so
1639 that it accepts commands in but does not execute them more than once
1642 * Added silc_net_localhost(), to return local hostname, into
1643 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1644 that must be initialized before calling silc_client_init.
1646 * Added new function: silc_server_send_notify_on_channels to send
1647 notify messages to all channels client has joined. It is assured
1648 that the message is sent only once per client.
1650 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1651 lib/silcutil/silcutil.[ch] as silc_format function. The new
1652 function is generic and is used by server as well, not only by
1653 the logging routines.
1655 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1656 the provided version string was not acceptable. Added new function:
1657 silc_ske_check_version into lib/silcske/silcske.h. The function
1658 must be implemented by the application (client or server) and it
1659 does not reside in the SKE library. The function checks the version
1660 string remote end sent.
1662 * Added back pointers (to opaque context and to SilcSocketConnection)
1663 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1665 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1666 duplicate packet context structure.
1668 * Changed `notify' client operation to send same arguments as client
1669 receives from server except for ID's. ID's are mapped to correct
1670 ID entry and that is returned. Also, if channel entry is not sent
1671 by server but the notify is for channel the channel entry is sent
1672 to application (otherwise application doesn't know that it is for
1673 channel (library gets it from packet's Destination ID)).
1675 * Added silc_client_remove_from_channels into client library to
1676 remove a client from all channels it has joined to. Used when
1677 received SIGNOFF notify from server. Added also new function
1678 silc_client_replace_from_channels to replace old ID entry with
1679 new ID entry on all channels. Used when received NICK_CHANGE
1682 * Fixed ID Cache list handling in silc_idlist_get_client in
1683 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1684 to get (or query) client by ID.
1686 * Updated TODO list.
1688 * Added connection authentication status message defined by the
1689 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1690 support for these into the code in client and server side.
1692 * Added generic function silc_client_send_command to send any command
1693 with variable argument list. Application should use this function
1694 to send commands if the command functions provided by the library
1695 does not suite for the application's user interface needs.
1697 * Added new `failure' client operation. Application is notified about
1698 received failure packet if client is executing a protocol. In this
1699 case the protocol's execution has failed.
1701 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1702 is required by the protocol.
1704 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1705 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1708 * Added status flag to SilcSKE object to indicate realtime status
1709 of the SKE protocol.
1711 * Application receives now exactly same command reply arguments as
1712 the library receives from server. However, if ID is received the
1713 corresponding ID entry is returned to the application (eg. Client
1714 ID is mapped to correct SilcClientEntry entry and that is returned).
1715 Changed command_reply client operation due to this change.
1717 * Changed all ID's in commands and in command replys as ID Payloads.
1718 Change affected both client and server side codes.
1720 All ID's sent in SILC network (with execption of ID's in SILC
1721 Packet header) are sent in ID Payload to support variable length
1724 * Server now notifies nick changes and notifies all clients on
1725 the channels about the new nickname (about the new Client ID,
1728 * Implemented CMODE command to change channel modes. Supports all
1729 channel modes defined by the protocol specs except ban and invite
1730 lists. (Also, private channel key mode is supported but support for
1731 setting private channel key in client is missing, thus, this mode
1732 has no effect on client side (except that server requires that the
1733 client uses private channel key and normal channel traffic does not
1736 Also, invite mode works per se, but INVITE command does not work
1737 yet correctly, so you can set channel as invite only channel but
1738 inviting clients to the channel does not work (it is yet to be
1739 thought what's the best way to do it).
1741 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1742 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1743 Implemented CUMODE command to change user's mode on the channel.
1744 Supports all modes defined by the protocol specs.
1746 * Added NAMES command reply to return users modes on the channel.
1748 * Removed unnecessary and slow ciphers from lib/silccrypt.
1750 * Set SO_KEEPALIVE option to connection sockets by default.
1752 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1754 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1755 redefined the Notify Payload into protocol specs.
1757 * Added silc_id_payload_parse_id to get ID directly from raw
1760 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1762 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1763 accept searching by Client ID as well.
1765 * Added support for LEAVE and SIGNOFF notify types in client library.
1767 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1768 to parse ID Payload from raw data.
1770 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1772 * Added flags parameter into silc_ske_assemble_security_properties
1773 function in lib/silcske/silcske.[ch].
1775 * Changed notify client operation to fit better for notify messages
1776 sent by server. The notify payload received from server is now
1777 passed to the application (after parsing it to SilcNotifyPayload).
1778 It is application's responsibility to retrieve the arguments
1779 from the payload and show the message the way it wants. The message
1780 sent by server is implementation specific.
1782 * Changed public keys to comply with the protocol specification.
1783 Old public keys are not supported anymore and are not compatible.
1785 * Removed nickname from Channel Payload as the latest draft removed
1786 it. The client must resolve the nickname from the NAMES command
1787 reply received when it joined the channel.
1789 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1791 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Fixed some errors in protocol specification drafts.
1795 * Created lib/silccore/silcnotify.c to implement Notify Payload
1796 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1797 generic payloads described by protocol specifications. The file
1798 includes implementations for ID Payload and Argument Payload.
1800 * Changed Command Payload implementation to use the new Argument
1801 Payload. Changed command_xxxx_payload to command_payload_xxxx
1802 to comply with SILC coding conventions.
1804 * Added suppport for Argument Payload handling in Notify Payload
1805 implementation as protocol requires it. Added the new support
1806 into server and client lib as well.
1808 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1810 * Added support for multiple nicknames on same channel. [n] is
1811 added locally to the nickname if there are more than one same
1812 nicknames on the channel.
1814 * Server now sends all nicknames that matched WHOIS request.
1815 Client also shows the list received from server.
1817 * Added TOPIC command to client side. User can now set and show
1818 current topic on channel.
1820 * Added MOTD command to client and server. Also, server sends the
1821 motd when client connects to the server.
1823 * Changed version strings to comply ISO 8601.
1825 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1827 * Fixed protocol error handling in client library. It should now
1828 cope even if the SKE fails for some reason.
1830 * Made new protocol specification drafts for submitting to IETF.
1832 * Implemented TOPIC command to server in silcd/command.c.
1834 * Added two new notify types into lib/silccore/silcnotify.h:
1835 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1836 notify nickname change and topic setting/change on a channel.
1838 * API change of command_reply operation in client library. The
1839 application gets now the status type received from server as well.
1841 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1843 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1845 * Cras fixed and optimized the packet handling even further and
1846 it should work now. Minor change to the prototype of function
1847 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1849 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1851 * Added new function into lib/silcutil/silcschedule.[ch]:
1852 silc_schedule_with_fd to select() a specified fd. The function
1853 returns after timeout expires or data arrives or goes. The
1854 function is used by packet routines to wait that all data is
1855 received from network.
1857 * Fixed data reading from network in lib/silccore/silcpacket.c.
1858 The code now assures that all data is read from the fd and then
1859 continues packet processing. This was a bug fix since the code
1860 used to drop some data in some circumstances.
1862 * Added new function into lib/silcclient/client.[ch]:
1863 silc_client_start_key_exchange to start key exchange after
1864 connection has been established to server. The code internally
1865 now uses this funtion but its main purpose was to provide it
1866 for applications that perform their own connecting. After
1867 application has created a connection it merely calls this
1868 function to start the key exchange between client and server.
1869 The library takes care of everything else after that.
1871 Updated also lib/silcclient/README to explain the usage of
1874 * Do not send to application information that connection has
1875 been established. Application gets notified it by connect
1878 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1880 * Applied cras's patch to add silc_schedule_one function. The
1881 function runs scheduler once and returns.
1883 * Fixed the scheduler after cras messed it up. The timeout
1884 handling works now as it's supposed to work.
1886 * Added into lib/silccore/ silcnotify.h to include notify
1887 message types support. Changed silc_server_send_notify*
1888 functions, in server.[ch], to support those new notify types.
1889 Added the support for the notify types into client library,
1890 as well. Added new notify client operation into ops.h in
1893 * Changed silc_server_packet_send_to_channel to send normal
1894 packets instead of just channel message packets. The function
1895 is now used to send the notify packets to channels. It is not
1896 used to send channel message packets anymore, as server never
1899 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1900 va_arg()s as it seems to require it nowadays. I guess, if SILC
1901 is compiled with older va_arg() the new code should work anyway.
1903 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1905 * Splitted core library. Core library (lib/silccore) includes
1906 now only SILC protocol specific core (and common) components.
1907 Created new utility library (lib/silcutil) that includes more
1908 generic purpose stuff. The stuff for util library was taken
1909 from the old core library. This was minor and easy split.
1911 * Created SILC Client Library (lib/silcclient) that includes
1912 implementation of the SILC client without user interface. This
1913 was major move from silc/ directory. The code has been changed
1914 so that it is transparent towards the user interface. The
1915 silc/ directory includes now the same user interface as before
1916 and it uses the new client library. Read lib/silcclient/README.
1917 Basicly, the client library performs everything else related
1918 to SILC except user interface handling. Also, configuration
1919 files are considered to be part of user interface and library
1920 does not handle them.
1922 This change also changed a lot of structures, function naming etc.
1923 Most important change was that SilcClientWindow object was
1924 renamed to SilcClientConnection in the client library. Created
1925 also new file lib/silcclient/ops.h. Also added new files
1926 silc/local_command.[ch] and silc/client_ops.[ch].
1928 All these changes were made to make it easier for user interface
1929 designers to create what ever user interface for the SILC client
1932 It is also expected that the server will be moved to lib
1933 directory as well and SILC Server Library will be created;
1934 sometimes in the future.
1936 * Removed Local commands from lib/silccore/silccommand.h as
1937 they are application specific and new client library does not
1938 handle any of those anymore.
1940 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1941 old client implementation in silc/.
1943 * Added support for callback functions in SILC_LOG_* macros.
1944 Application can now set its own callbacks that will be called
1945 instead of using the default functions that will always print
1946 the debug messages to stderr (or stdout). Also, debugging can
1947 now be disabled by setting silc_debug to FALSE and re-enabled by
1948 setting it to TRUE. Note, that logging will still work even
1949 if debugging is disabled.
1951 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1952 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1953 silc_log_reset_debug_callbacks.
1955 * To enable debugging in silc client one must give now -d
1956 option on command line.
1958 * Changed silc_schedule_init to automatically allocate task queues
1959 if they are not allocated before calling it.
1961 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1963 * Added GMP 3.1 into math library.
1965 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1967 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1968 a channel in SILC network. The packet is used by servers and
1969 routers to notify other routers that user has left a channel.
1970 This little feature was missing until now. Added the feature
1971 to protocol specification as well.
1973 Added functions: silc_server_send_remove_channel_user and
1974 silc_server_remove_channel_user into server.[ch].
1976 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1977 lib/silccore/silcpacket.h. However, they are not implemented
1980 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1982 * Fixed joining to a channel and sending channel messages
1983 between server and router. The channel message sending should
1984 now work inside a cell.
1986 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1988 * Fixed the private message sending between server and router.
1989 The private message sending should now work inside a cell.
1991 * Added silc_server_replace_id into server.[ch] to replace
1992 existing ID in the SILC network.
1994 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1995 and silc_idlist_replace_server_id into idlist.[ch] in server.
1997 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1999 * Fixed the server to server connections. Server can again now
2000 connect to router. Router to router connections probably does
2003 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2005 * Added dynamic protocol registering support. Now protocols can
2006 registered and unregistered on the fly. Patch by cras.
2008 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2010 * Added lib/contrib directory to hold routines that some platforms
2011 don't have but are needed by SILC.
2013 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2014 into lin/contrib to provide getopt() and getopt_long() for
2015 those who don't have it.
2017 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2019 * Added AWAY command to client. When away message is set and
2020 client receives a private message packet the client automatically
2021 replies to the sender with the away message.
2023 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2024 bug seemed to be the cause of recent problems when compiling
2027 * Added version detection support to SKE protocol specification
2028 and added the new changes to the SKE implementation as well.
2029 There were other minor changes in the SKE protocol as well.
2031 Many changes in lib/silcske/silcske.[ch] and in
2032 lib/silcske/payload.[ch].
2034 * Added ^U functionality, clear input line. Patch from cras.
2036 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2038 * Mainly small bugfixes on core library. Fixed some debugging
2039 logging and buffer overflow in silclog.c.
2041 * Updated config.sub and config.guess on the distribution tree.
2043 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2045 * Added command lagging support in server. Client may execute
2046 commands now only once in two seconds.
2048 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Optimized packet reception. MAC computation and checking is now
2051 also more optimized. A lot previously duplicated code is now
2052 used as generic by both client and server.
2054 * Fixed key pair generation in clientutil.c
2056 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2058 * Added into lib/silccore/silcbufutil.[ch] new function;
2059 silc_buffer_realloc.
2061 * Moved generic packet sending/encryption functions to
2062 lib/silccore/silcpacket.[ch] from client and server. Some
2063 rewriting of the functions.
2065 * Moved all generic packet reception/decryption functions to
2066 lib/silccore/silcpacket.[ch] from client and server. The
2067 packet processing is now much cleaner in both client and server.
2068 These were major changes in both client and server.
2070 * Created many common functions in server to do packet sending.
2071 Previously code were duplicated a lot, this has been removed
2074 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2076 * Rewrote major parts of the ID cache system. Don't know
2077 whether it is better now or not but at least the API is more
2080 * Major rewrite on ID cache stuff on client because of the ID
2081 cache API changes. Added idlist.c to client.
2083 * Also major rewrite on ID cache stuff on server as well.
2084 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2085 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2086 in hand, instead they are all put into the ID cache system now.
2087 All server_idlist_* routines uses ID cache now instead of
2088 traversing its own lists (those lists does not exist anymore).
2089 SilcIDList though still exists. Also, SilcXXXEntry's are
2092 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2094 * Finally made the SKE implementation compliant to the protocol
2095 specification. All mp integers are now binary encoded as
2096 opposed being HEX encoded.
2098 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2101 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2102 functions: silc_[encode/decode]_pem. Also added function
2103 silc_encode_pem_file to PEM encode with newlines ('\n') for
2106 * SILC public keys are now encoded either PEM or binary. Same
2107 option is for private keys as well. By default private keys
2108 are binary encoded and public keys PEM encoded. Silly HEX
2109 encoding were removed.
2111 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2112 function to create fingerprints.
2114 * Fixed a bug in SHA1; does not change the original data anymore.
2116 * Partly implemented INFO command on client and server side.
2117 Fixed CLEAR command. Changes to SERVER command; show current
2118 server(s) when giving command without arguments. Added
2119 VERSION command to client.
2121 * Added check to server that unregistered connections cannot
2122 execute commands (unless it is specificly allowed).
2124 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2126 * Fixed screen refresh.
2128 * Fixed channel joining bug from client. On some circumstances
2129 client tried to join to a channel it had already joined.
2131 * Added public key verification process into client's protocol.c.
2132 The client now verifies the public key from user and saves
2133 it into ~./silc/serverkeys/ directory.
2135 Added into: clientutil.[ch]: silc_client_verify_server_key.
2137 * Changed SKE protocol's silc_ske_initiator_finish function
2138 to accept callback function that verifies the received public
2139 key. Removed old silc_ske_verify_public_key function.
2141 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2143 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2144 silc_pkcs_private_key[_data]_set.
2146 * Made the password and public authentication more cleaner in
2147 server's protocol.c.
2149 * Removed historic and obsolete protocol `channel_auth' from
2150 both client and server.
2152 * Removed wrong way of sending command status messages from
2153 server to client in server's command.c. The old way violated
2154 protocol specification.
2156 Changes to silccore/silccommand.[ch]: removed
2157 silc_command_encode_status_payload -> not needed anymore,
2158 changed silc_command_encode_payload_va to accept extra
2159 argument on variable argument list. The argument type must
2160 now be provided to the function. Also, added new function:
2161 silc_command_encode_reply_payload_va which is same as
2162 normal command_encode_payload_va except command status type
2163 is provided as extra argument.
2165 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2167 * Added ~./silc directory handling. The directory includes the
2168 public and private keys for the client.
2170 Added silc_client_check_silc_dir, silc_client_create_identifier
2171 and silc_client_load_keys.
2173 * Implemented SILC protocol compliant public key. Added public
2174 and private key saving to and loading from files.
2176 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2177 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2178 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2179 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2180 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2182 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2183 silc_pkcs_load_[public/private]_key.
2185 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2187 * Added silc_server_get_route (route.[ch]) to get connection
2188 data for the fastest route for given ID.
2190 * Implemented INVITE command on client and server. The command
2191 were re-defined in the SILC Protocol Specification and the
2192 implementation now complies with the specification.
2194 * Implemented PING command on client and server.
2196 * Implemented NAMES command on client and server. The server side
2197 supports currently only normal server not router server yet.
2198 Some changes to NAMES definition in SILC protocol specification.
2200 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Implemented LEAVE command on client and server.
2204 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2205 again. This change was made to the protocol as well. Server
2206 should not violate the protocol specification anymore.
2208 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2210 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2211 was tested. SOCKS4 was not but should work anyway.
