3 * Added assert()s to buffer formatting and unformatting routines
4 to assert (if --enable-debug) when error occurs. Affected
5 file: lib/silcutil/silcbuffmt.c.
7 * Changed to auto-reconnect to check whether the remote host is
8 router and register the re-connect timeout if it is. It used
9 to check that whether we are normal server, but router must do
10 auto-reconnect with another router as well. Affected file
13 * Removed the [<key len>] option from CMODE command as the cipher
14 name decides the key length, nowadays. See the defined ciphers
15 from the protocol specification.
17 * Added [<hmac>] option to the CMODE command to define the HMAC
18 for the channel. Added SILC_CMODE_HMAC channel mode.
20 * Added [<hmac>] option for the JOIN command so that user can
21 select which HMAC is used to compute the MACs of the channel
24 * Added Hmac field to the Channel Message Payload. The integrity
25 of plaintext channel messages are now protected by computing
26 MAC of the message and attaching the MAC to the payload. The
27 MAC is not encrypted. Now, it is clear that this causes some
28 overhead to the size of the packet but rationale for this is that
29 now the receiver can verify whether the channel message decrypted
30 correctly and also when private keys are set for the channel the
31 receiver can decrypt the packet with several keys and check from
32 the MAC which key decrypted the message correctly.
34 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
35 lib/silccrypt/silccipher.[ch].
37 * Added silc_hash_len to return the digest length into the
38 lib/silcrypt/silchash.[ch].
40 * Rewrote parts of Silc Channel Payload interface in the
41 lib/silccore/silcchannel.[ch]. The encode function now also
42 encrypts the packet and parse function decrypts it.
44 * Channel message delivery between routers was broken after the
45 channel key distribution was fixed earlier. The channel key
46 was used be to distributed to other routers as well which is not
47 allowed by the protocol. Now this is fixed and channel keys
48 really are cell specific and the channel message delivery between
49 routers comply with the protocol specification.
51 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
53 * Fixed a minor formatting bug in the SKE's key material processing.
54 It actually might have processed the keys wrong way resulting
57 * Redefined the mandatory HMAC algorithms and added new algorithms.
58 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
59 and hmac-md5 truncated to 96 bits. The mandatory is now
60 hmac-sha1-96. Rest are optional (including the one that used
61 to be mandatory). Rationale for this is that the truncated HMAC
62 length is sufficient from security point of view and can actually
63 make the attack against the HMAC harder. Also, the truncated
64 HMAC causes less overhead to the packets. See the RFC2104 for
67 * Added new [hmac] configuration section. The SKE used to use
68 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
69 is of course wrong. The official names that must be proposed in
70 the SKE are the ones defined in the protocol specification
71 (hmac-sha1-96 for example). The user can configure any hmac
72 using any hash function configured in the [hash] section. At
73 least, the mandatory must be configured.
75 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
77 * Added HMAC list to the SKE proposal list. It has now both
78 hash algorithm list and HMAC list. This makes the protocol
79 incompatible with previous versions. The SKE now seems to work
80 the way it is supposed to work, for the first time actually.
82 * Defined plain Hash algorithms to the protocol specification.
85 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
87 * Implemented support for key agreement packets into the server.
88 Added functions silc_server_key_agreement and
89 silc_server_send_key_agreement. Other than these functions,
90 server has nothing to do with this packet.
92 * Added support for private message key packets into the server.
93 Added functions silc_server_private_message_key and
94 silc_server_send_private_message_key.
98 * Changed the silc_[client|server]_protocol_ke_set_keys to be
99 called in the protocol's final callback instead in the END
100 protocol state. This makes a little more sense and in the same
101 time in client we can use the same protocol routines for normal
102 key exchange and to key agreement packet handling as well.
104 * Added to both client's and server's KE protocol context the
105 SilcSKEKeyMaterial pointer to save the key material. We will
106 bring the key material to the protocol's final callback by doing
107 this. The final callback must free the key material.
109 * Added SKE's packet_send callback into client's KE protocol
110 context so that the caller can choose what packet sending function
111 is used. This way we can use different packet sending when
112 doing normal SKE when doing key agreement packet handling (in
113 the key agreement packet handling we do not want to encrypt
116 * Implemented the responder side of the key agreement routines
117 in the client. The client can now bind to specified port and
118 accept incoming key negotiation. The key material is passed
119 to the application after the protocol is over.
121 * Implemented the processing of incoming Key Agreement packet
122 in the client. Added function silc_client_key_agreement to
125 * Implemented the intiator side of the key agreement routines
126 in the client. The client can now initiate key agreement with
127 another remote client. The key material is passed to the
128 application after the protocol is over.
130 * Created client_keyagr.c to include all the key agreement
133 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
134 SILC_TASK_CALLBACK except that it is not static.
136 * Created client_notify.c and moved the Notify packet handling
137 from the client.[ch] into that file.
139 * Created client_prvmsg.c and moved all private message and
140 private message key routines from the client.[ch] into that file.
142 * Create client_channel.c and moved all channel message and
143 channel private key routines from the client.[ch] into that file.
145 * Changed silc_client_get_client_by_id_resolve to resolve with
146 WHOIS command instead of IDENTIFY command, in the file
147 lib/silclient/idlist.c.
149 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
151 * Implemented the SKE's responder side to the Client library.
153 * When FAILURE is received to the protocol do not trust it
154 blindly. Register a timeout to wait whether the remote closes
155 the connection as it should do it, only after that process the
156 actual failure. This was changed to both client and server.
158 * Added client_internal.h to include some of the structures
159 there instead of client.h in lib/silcclient/.
161 * Added function silc_task_unregister_by_callback to unregister
162 timeouts by the callback function.
164 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
166 * Some "Incomplete WHOIS info" errors has been appearing on the
167 log files. Took away the entry->userinfo check from WHOIS
168 reply sending. The entry->userinfo is now " " if client did not
169 provide one. I thought this was fixed earlier but something
170 is wrong still. Let's see if the error still appears.
172 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
174 * Fixed a minor bug in the login when the channel key is
175 re-generated in the server. It used to generate the key in
176 wrong order and thus caused problems in the channel traffic.
178 * Fixed a minor bug in channel key distsribution after
179 KICK command. The key was not sent to the router even though
182 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
184 * Added silc_ske_process_key_material_data as generic routine
185 to process any key material as the SILC protocol dictates. The
186 function is used by the actual SKE library but can be used by
187 applications as well. This relates to the private message keys
188 and the channel private keys since they must be processed the
189 same way the normal SILC session keys. The protocol dictates
190 this. Affected files: lib/silcske/silcske.[ch].
192 Added also silc_ske_free_key_material to free the
193 SilcSKEKeyMaterial structure.
195 * Defined silc_cipher_set_key function to set the key for
196 cipher without using the object's method function. The affected
197 files: lib/silccrypt/silccipher.[ch].
199 * Implemented silc silc_client_add_private_message_key,
200 silc_client_add_private_message_key_ske,
201 silc_client_del_private_message_key,
202 silc_client_list_private_message_keys and
203 silc_client_free_private_message_keys functions in the
206 Added functions silc_client_send_private_message_key to send
207 the Private Message Key payload and silc_client_private_message_key
208 to handle incoming Private Message Key payload.
210 * Added Cipher field to the Private Message Key payload to set
211 the cipher to be used. If ignored, the default cipher defined
212 in the SILC protocol (aes-256-cbc) is used.
214 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
216 * Removed lib/silcclient/ops.h file.
218 Redefined parts of the SILC Client Library API. Created new
219 file silcapi.h that deprecates the ops.h file and defines the
220 published Client Library API. Defined also private message key
221 API and channel private key API into the file.
223 This is the file that the application must include from the
224 SILC Client Library. Other files need not be included by
225 the application anymore.
227 * Added new key_agreement client operation callback and also
228 defined the Key Agreement library API for the application.
230 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
232 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
233 is used by clients to request key negotiation between another
234 client in the SILC network. If the negotiation is started it
235 is performed using the SKE protocol. The result of the
236 negotiation, the secret key material, can be used for example
237 as private message key.
239 Implemented the Key Agreement payload into the files
240 lib/silccore/silauth.[ch].
242 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
244 * Redefined ciphers for the SILC protocol. Added some new ciphers
245 and defined the key lengths for the algorithms. Changed the
246 code accordingly. The default key length is now 256 bits.
248 * Fixed SKE key distribution function silc_ske_process_key_material
249 when the key length is more than 128 bits. The default key
250 length in SILC is now 256 bits.
252 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
253 to indicate unsupported algorithm.
255 * Renamed rijndael.c to aes.c and all functions as well.
257 * Fixed a long standing channel key setting bug in client library.
258 Weird that it has never surfaced before.
260 * Fixed bug in channel deletion. If the entire channel is removed
261 then it must also delete the references of the channel entry
262 from the client's channel list as the client's channel entry and
263 the channel's client entry share same memory.
265 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
267 * Implemented CONNECT and SHUTDOWN commands in the client.
269 * Implemented CLOSE command to the client.
271 * Added the function silc_idlist_find_server_by_name into the
272 files silcd/idlist.[ch].
274 Added the function silc_idlist_find_server_by_conn into the
275 files silcd/idlist.[ch].
277 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
279 * DIE command was renamed to SHUTDOWN. Updated the both code
282 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
283 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
285 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
288 * Added function silc_server_create_connection function to create
289 connection to remote router. My server implementation actually
290 does not allow router to connect to normal server (it expects
291 that normal server always initiates the connection to the router)
292 so the CONNECT command is only good for connecting to another
295 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
297 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
298 or some other client was kicked from the channel.
300 Implemented the handling of the notify type to both client
303 Implemented silc_server_send_notify_kicked to send the KICKED
304 notify. It is used to send it to the server's primary router.
306 * Implemented the KICK command into server and client.
308 * Added `query' argument to the silc_idlist_get_client function
309 to indicate whether to query the client from server or not if
312 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
313 to indicate that the client is not channel founder.
317 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
319 * Removed the rng context from SilcPacketContext structure and
320 changed that the packet routine uses the Global RNG API.
322 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
324 * Added support for quit message that client can "leave" on the
325 channel when it quits the SILC. It is ditributed inside the
326 SILC_NOTIFY_TYPE_SIGNOFF notify type.
328 Added silc_server_free_client_data that will take the
329 signoff message as argument.
331 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
333 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
335 * Updated parts of the protocol specification to keep it up
338 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
340 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
341 payloads in one packet.
343 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
344 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
345 use now the new List flag.
347 * Also deprecated the following packet types: REPLACE_ID,
348 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
350 * Added list support for Notify packet in server.
352 * Added silc_server_send_notify_channel_change to send the
353 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
354 the silc_server_send_replace_id.
356 * Added silc_server_send_notify_nick_change to send the
357 NICK_CHANGE notify type. Deprecates the function
358 silc_server_send_replace_id.
360 * Added silc_server_send_notify_join to send the JOIN notify type.
361 Deprecates the function silc_server_send_new_channel_user.
363 * Added silc_server_send_notify_leave to send LEAVE notify type.
364 Deprecates the function silc_server_send_remove_channel_user.
366 * Added silc_server_send_notify_cmode and
367 silc_server_send_notify_cumode to send CMODE and CUMODE notify
368 types. Deprecates the silc_server_send_set_mode function.
370 * Added SERVER_SIGNOFF notify type to indicate that server has
371 quit. This means that all clients on the channel from that
372 server will drop. This can be also used when netsplit happens.
374 Deprecated REMOVE_ID packet type since it is not needed anymore
377 Added silc_server_send_notify_server_signoff to send the
378 SERVER_SIGNOFF notify type. Deprecates the function
379 silc_server_send_remove_id.
381 Added also silc_server_send_notify_signoff to send the
384 * Employed the PKCS #1. It is the mandatory way to do RSA in the
385 SILC protocol from this day on. Changed the protocol
386 specification as well.
388 * Added silc_server_send_notify_topic_set to send TOPIC_SET
389 notify type. It is used between routers to notify about
390 topic changes on a channel.
392 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
395 * Partly updated the protocol specification to comply with the
396 changes now made. It is still though a bit outdated.
398 * The JOIN notify type now takes one extra argument <Channel ID>.
399 The packet used to be destined to the channel but now the
400 JOIN type may be sent as list thus it is impossible to
401 destine it to any specific channel. By adding this argument
402 it is again possible.
404 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * Added CREDITS file. The CHANGES and CREDITS file will appear
407 in the distribution as well.
409 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
411 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
412 types in the server's silcd/packet_receive.c.
414 * Implemented CMODE and CUMODE to work in router environment.
416 * Fixed minor encoding and decoding buglet from the
417 lib/silccore/silcmode.c.
419 * Fixed buffer overflow from lib/silcclient/command.c in USERS
422 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
424 * Changed all SilcConfigServer* and silc_config_server* to
425 SilcServerConfig* and silc_server_config*, respectively.
428 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
430 * Associated the ID (client or server ID) to the Authentication
431 Payload to avoid any possibility of forging. Updated the
432 protocol specification and the code accordingly.
434 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
436 * The RSA key length is now save to the RsaKey context in the
437 key generation process in lib/silccrypt/rsa.c. The key length
438 is now used to figure out the maximum size of the block allowed
439 to be encrypted/signed.
441 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
442 is equivalent to the silc_mp_mp2bin but does not allocate any
445 * Changed silc_mp_mp2bin API to take length argument. If it is
446 non-zero then the buffer is allocated that large. If zero, then
447 the size is approximated using silc_mp_sizeinbase, which however
450 * Created Global RNG API which is global RNG that application can
451 initialize. After initializing, any routine anywhere in the
452 code (including library) can use RNG without allocating a new
453 RNG object. This was done to allow this sort of use of the
454 RNG in code that has no chance to allocate RNG object. All
455 applications currently allocate this and many routines in the
456 library use this. Affected file lib/silccrypt/silcrng.[ch].
458 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
459 it to use the Global RNG API.
461 * Defined Authentication Payload into protocol specification that
462 is used during SILC session to authenticate entities. It is
463 used for example by client to authenticate itself to the server
464 to obtain server operator privileges.
466 Implemented this payload into the lib/silccore/silcauth.[ch].
467 Implemented also routines for public key based authentication
468 as the new protocol specification dictates.
470 Moved definitions of different authentication methods from
471 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
473 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
474 silc_pkcs_verify and silc_pkcs_sign_with_hash and
475 silc_pkcs_verify_with_hash functions into the file
476 lib/silccrypt/silcpkcs.[ch].
478 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
480 * The client entry's userinfo pointer must be always valid.
481 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
482 will fail since it requires the userinfo. Now, the userinfo
483 is allocated as "" if actual userinfo does not exist. Actually,
484 it must exist and it is totally Ok to drop client connections
485 that does not announce the userinfo. However, we will make
486 this workaround for now.
488 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
489 to return the remote port by socket.
491 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
493 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
494 SILC_SERVER_PENDING_EXEC and added an new macro
495 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
496 data or when error occurs while processing the pending command.
498 Added new argument `destructor' into silc_server_command_pending
499 and to the SilcServerCommandPending object. This destructor is
500 now called after calling the pending callback or if error occurs
501 immediately. If error occurs the actual pending callback won't
502 be called at all - only the destructor. The destructor may be
503 NULL if destructor is not needed.
505 All this applies for client library code as well. Similar
506 changes were made there as well for the pending commands.
508 In the client, the application must now allocate the
509 SilcClientCommandContext with the silc_client_command_alloc
512 * Added reference counter to the SilcServerCommandContext. Added
513 function silc_server_command_alloc and silc_server_command_dup
516 Same type of functions added to the client library for the same
519 * Removed the cmd_ident from IDListData away since it is now
520 global for all connections. It is the command identifier used
521 in command sending and with pending commands. The affected file
524 * Added reference counter to the SilcSocketConnection objecet to
525 indicate the usage count of the object. The object won't be
526 freed untill the reference counter hits zero. Currently only
527 server uses this, and client ignores it. The client must be
528 set to use this too later. The affected files are
529 lib/silccore/silcsockconn.[ch]. Added also the function
530 silc_socket_dup to increase the reference counter.
532 This was mainly added because it is possible that the socket
533 is removed underneath of pending command or other async
534 operation. Now it won't be free'd and proper DISCONNECTING
535 flags, etc. can be set to avoid sending data to connection that
536 is not valid anymore.
538 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
539 the connection. After that it sets SILC_SET_DISCONNECTED.
540 It is, however, possible that the socket data is not still freed.
541 The silc_server_packet_process now checks that data is not
542 read or written to connection that is DISCONNECTED. The socket
543 get's freed when the reference counter hits zero.
545 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
547 * Changed the client operation API: channel_message operation's
548 `sender' is now the client entry of the sender, not the nickname
549 and the `channel' is the channel entry, not the channel name.
551 In the private_message operation the `sender' is now also the
552 client entry of the sender not the nickname.
554 Affected file is lib/silcclient/ops.h and all applications
555 using the client operations.
557 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
559 * Moved the calling of ops->connect() from connect_to_server_final
560 into receive_new_id functin since that is the point when the
561 client is actually allowed to send traffic to network. The
562 affected file is lib/silcclient/client.c.
564 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
566 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
567 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
568 (if needs broadcasting) instead of broadcasting the packets one
569 by one which would make a burst in the network traffic.
571 * Added `broadcast' argument to the functions in silcd/server.[ch]
572 silc_server_create_new_channel[_with_id] to indicate whether
573 to send New Channel packet to primary router.
575 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
577 * Added new function into the silcd/server.[ch] files:
578 silc_server_create_new_channel_with_id to create new channel with
579 already existing Channel ID.
581 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
582 lib/silccore/silcpacket.h. This packet is used t send list of
583 Set Mode payloads inside one packet. Server uses this to set
584 the modes for the channels and clients on those channels, that it
585 announced to the router when it connected to it. The protocol
586 specification has been updated accordingly.
588 * The silc_server_new_channel did not handle the packet coming
589 from normal server as it normally does not send that. However,
590 when it announces its channels it does send it. Implemented
591 the support for that.
593 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
594 into the file lib/silccore/id.h.
596 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
598 * Fixed memory leaks in the functions silc_idlist_del_client,
599 silc_idlist_del_channel and silc_idlist_del_server in the file
600 silcd/idlist.c. All of those leaked like a sieve.
602 * Fixed some small memory leaks in the client's function
603 silc_client_notify_by_server.
605 * Added functions into silcd/server.c: silc_server_announce_clients,
606 silc_server_announce_channels and silc_server_announce_server.
607 These functions are used by normal and router server to announce
608 to its primary router about clients, channels and servers (when
609 router) that we own. This is done after we've connected to the
612 These functions effectively implements the following packet types:
613 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
614 and SILC_PACKET_NEW_ID_LIST.
616 * Added new functions into the silcd/packet_receive.[ch]:
617 silc_server_new_id_list, silc_server_new_channel_list and
618 silc_server_new_channel_user_list to handle the incoming
619 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
621 * Added support of changing Channel ID in the function
622 silc_server_replace_id. If the server that announces a channel
623 to the router already exists in the router (with same name but
624 with different Channel ID), router is responsible to send
625 Replace ID packet to the server and force the server to change
626 the Channel ID to the one router has.
628 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
629 client that the Channel ID has been changed by the router. The
630 normal server sends this to the client. Client must start using
631 the new Channel ID as the channel's ID.
633 Implemented handling of this new type into lib/silcclient/client.c
634 into the function silc_client_notify_by_server.
636 * Added new function silc_idlist_replace_channel_id into the files
637 silcd/idlist.[ch] to replace the Channel ID.
639 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
641 * Call silc_server_command_identify_check always when processing
642 the IDENTIFY command in silcd/command.c
644 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
646 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
647 send keepalive packets. The packet can be sent by clients,
650 Added function silc_socket_set_heartbeat into the file
651 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
652 If not set, the heartbeat is not performed. The actual
653 heartbeat is implemented in the low level socket connection
654 library. However, application is responsible of actually
657 Added silc_server_send_heartbeat to send the actual heartbeat
658 packet into silcd/packet_send.[ch]. Server now performs
659 keepalive with all connections.
661 * Added silc_task_get_first function into lib/silcutil/silctask.c
662 to return the timeout task with shortest timeout. There was a bug
663 in task unregistration that caused problems. TODO has been
664 updated to include that task system must be rewritten.
666 * The client library will now resolve the client information when
667 receiving JOIN notify from server for client that we know but
668 have incomplete information.
670 * Rewrote parts of silc_server_remove_from_channels and
671 silc_server_remove_from_one_channel as they did not remove the
672 channel in some circumstances even though they should've.
674 * Encryption problem encountered in server:
676 The LEAVE command used to send the Channel Key packet to the
677 router immediately after generating it. However, the code
678 had earlier sent Remove Channel user packet but not immediately,
679 ie. it was put to queue. The order of packets in the router
680 was that Channel Key packet was first and Remove Channel User
681 packet was second, even though they were encrypted in the
682 reverse order. For this reason, MAC check failed. Now, this
683 is fixed by not sending the Channel Key packet immediately but
684 putting it to queue. However, this is more fundamental problem:
685 packets that are in queue should actually not be encrypted
686 because packets that are sent immediately gets encrypted
687 actually with wrong IV (and thus MAC check fails). So, packets
688 that are in queue should be encrypted when they are sent to
689 the wire and not when they put to the queue.
691 However, the problem is that the current system has not been
692 designed to work that way. Instead, the packet is encrypted
693 as soon as possible and left to the queue. The queue is then
694 just purged into wire. There won't be any fixes for this
695 any time soon. So, the current semantic for packet sending
698 o If you send packet to remote host and do not force the send
699 (the packet will be in queue) then all subsequent packets to the
700 same remote host must also be put to the queue. Only after the
701 queue has been purged is it safe again to force the packet
704 o If you send all packets immediately then it safe to send
705 any of subsequent packets through the queue, however, after
706 the first packet is put to queue then any subsequent packets
707 must also be put to the queue.
709 Follow these rules and everything works fine.
711 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
713 * Added new function silc_server_remove_clients_by_server to
714 remove all client entries from ID list when the server connection
715 is lost. In this case it is also important to invalidate all
716 client entires as they hold the invalid server entry. This
717 fixes fatal bug when server has lost connection and will reconnect
720 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Made some sanity checks to silc_server_daemonise like to check
723 whether the requested user and group actually exists.
725 * Added sanity check to SKE's silc_ske_responder_finish to check
726 that the public and private key actually is valid.
728 * Invalidate the client's nickname when receiving Replace ID
729 packet and the Client ID is being replaced. This means that the
730 server will query the nickname if someone needs it (client)
733 * Sort the ID Cache in client library when the ID Cache data
734 has changed (needs sorting).
736 * Do not allow for SILC client to create several connections to
737 several servers. The client does not support windows right now
738 and generating multiple connections causes weird behaviour.
740 Irssi-silc client does support windows and can handle several
741 connections without problems, see: www.irssi.org and SILC plugin.
743 * Fixed some places where client was added to the IDList. The
744 rule of thumb is following (in order to get everything right):
745 If the client is directly connected local client then the
746 `connection' argument must be set and `router' argument must be
747 NULL to silc_idlist_add_client function. If the client is not
748 directly connected client then the `router' argument must
749 bet set and the `connection' argument must be NULL to the
750 silc_idlist_add_client function.
752 * The funtion silc_server_packet_send_local_channel actually did
753 not check whether the client was locally connected or not. It
754 does that now. Fixed a bug related to LEAVE command.
756 * Fixed Remove Channel User payload parsing bug in server's
757 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
759 * The server's silc_server_save_channel_key now checks also the
760 global ID list for the channel as it might not be in the local
761 list. Fixed a bug related to LEAVE command.
763 * Is this the end of the [<unknown>] buglet that has been lurking
764 around for a long time? A little for loop fix in server's
765 silc_server_command_whois_parse that is used by both IDENTIFY
766 and WHOIS command. At least, this was a clear bug and a cause
767 of one type of [<unknown>] buglet.
769 * WHOIS and IDENTIFY commands call the function
770 silc_server_command_[whois/identify]_check function even if
771 we are not router server.
773 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
775 * Added --with-gmp configuration option. If set the GMP
776 is always compiled in the SILC source tree. If not set then
777 it is checked whether the system has the GMP3 installed. If
778 it has then the GMP won't be compiled (the system's headers
779 and library is used), if it doesn't have it then the GMP is
780 compiled in the SILC source tree.
782 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
784 * Changed RSA private exponent generation to what PKCS #1
785 suggests. We try to find the smallest possible d by doing
786 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
787 not security fix but optimization.
789 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
791 * Added new config entry [Identity] to fork the server and run
792 it as specific user and group. A patch from Bostik.
794 * Imported Dotconf configuration library into lib/dotconf.
795 This will be used to create the SILC configuration files later.
796 It will appear in the distsribution after this commit.
798 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
800 * A big code auditing weekend happening. Auditing code for
801 obvious mistakes, bugs and errors. Also, removing any code
804 Removed files for being obsolete:
806 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
807 inline in the file lib/silcutil/silcbuffer.h)
809 o lib/silcutil/silcbufutil.c (the header has inline versions)
811 Changed code to fix possible error conditions:
813 o The buffer formatting routines now check that the destination
814 buffer really has enough space to add the data. This applies for
815 both buffer formatting and unformatting
816 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
817 unformatting was changed to accomodate following rules:
818 XXX_*STRING_ALLOC will allocate space for the data into the pointer
819 sent to the function while XXX_*STRING will not allocate or copy
820 the data into the buffer. Instead it sets the pointer from the
821 buffer into the pointer sent as argument (XXX_*STRING used to
822 require that the pointer must be allocated already). This change
823 makes this whole thing a bit more consistent and more optimized
824 (note that the data returned in the unformatting with XXX_*STRING
825 must not be freed now). The routines return now -1 on error.
827 o Tried to find all code that use buffer_format and buffer_unformat
828 and added return value checking to prevent formatting and
829 especially unformatting errors and possible subsequent fatal
832 o Changed ske->x and ske->KEY to mallocated pointers in
833 lib/silcske/silcske.h. Fixed possible data and memory leak.
835 o Added return value checking to all *_parse* functions. Fixed
836 many memory leaks as well.
838 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
839 so that buffer overflows would not happen. All code now also
840 checks the return value as it can fail.
842 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
844 * Added reconnection support to server if the normal server looses
845 its connection to the router (for example if router is rebooted).
846 The server performs normal reconnection strategy implemented
847 to the server. Affected file silcd/server.c.
849 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
851 * Added new packet type SILC_PACKET_SET_MODE that is used to
852 distribute the information about changed modes (for clients,
853 channels and clients channel modes) to all routers in the
854 network. Updated the protocol specification accordingly.
856 Added functions into silcd/packet_send.c and
857 silcd/packet_receive.c: silc_server_send_set_mode,
858 silc_server_set_mode.
860 Added new files silcmode.[ch] into lib/silccore that implements
861 the encoding and decoding of Set Mode Payload. Added new type
862 SilcSetModePayload. Moved the definitions of different modes
863 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
865 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
867 * Oops, a little mistake in server's connection authentication
868 protocol. The protocol is not ended with FAILURE but with
869 SUCCESS if the authentication is Ok. :) Affected file is
872 * Implemented NICK_CHANGE notify handling in server in the file
873 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
874 the local clients on the channel. After the changing nickname
875 in router environment snhould work and the [<unknown>] nickname
876 should appear no more.
878 The silc_server_replace_id function that receives the Replace ID
879 payload now sends the NICK_CHANGE notify type also in the file
880 silcd/packet_receive.c
882 * Changed WHOIS and IDENTIFY command to support the maximum amount
883 of arguments defined in protocol specs (3328 arguments). This
884 fixed a bug that caused problems when there were more than three
887 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
889 * Added extra parameter, command identifier, to the
890 silc_client_send_command so that explicit command identifier
893 Changed that ID list routines uses specific command identifier
894 when sending WHOIS/IDENTIFY requests to the server so that they
895 can be identified when the reply comes back.
897 Affected files lib/silcclient/command.[ch],
898 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
900 * Added `sender' argument to silc_server_packet_send_to_channel
901 to indicaet the sender who originally sent the packet to us
902 that we are now re-sending. Ignored if NULL. Affected file
903 silcd/packet_send.[ch].
905 * Added some server statistics support in silcd/server_internal.h
906 SilcServerStatistics structure and around the server code. Also
907 send some nice statistics information when client is connecting
910 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
912 * Fixed channel ID decoding in server's JOIN command reply in
913 silcd/command_reply.c
915 * Fixed braodcasting of replace ID payload to not to send it if
916 we are standalone server in silcd/packet_receive.c.
918 * Fixed all channel message sending routines to not to send
919 packets to clients that has router set, since they are routed
920 separately in the same function earlier. Affects file
921 silcd/packet_send.c and all channel packet sending functions.
923 * In USERS reply, res_argv[i] are not allocated, the table
924 is allocated. Thus changed that free the table, not its
927 * In server's whois_check and identify_check if the client is
928 locally connected do not send any WHOIS commands - they are not
931 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
933 * Fixed some minor bugs in client when sending WHOIS command. The
934 arguments was in wrong order.
936 * Removed statis function add_to_channel from server in
937 silcd/command.c that was previously used with the joining but
940 * Tested USERS command in router environment successfully with two
941 routers, two servers and two clients.
943 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
945 * Reorganized the USERS command and command reply in client library
946 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
947 When the command is given by user we register a pending command
948 callback that will reprocess the command after the reply has been
949 received from the server. When reprocessing the packet we then
950 display the information. Thus, the USERS information is displayed
951 now in the command callback instead of in the command reply
952 callback. The processing of the command is same as previously
953 when server has sent the command reply in the JOINing process.
955 * Added to USERS command in silcd/command_reply.c to join the client,
956 we didn't use to know about, to the channel after we've created
957 a client entry for it. Also, for clienet we did know already still
958 check whether it is on the channel or not and add it if not.
960 * Removed silc_server_command_join_notify as the function and its
963 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
965 * Changed the client's pending command handling to the same as the
966 server's pending command handling. It is also now possible to
967 execute command reply functions from other command reply
968 function as the function callbacks for commands and command
969 replies are one and same. The pending commands are not static
970 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
971 in client connection context. Thus, pending commands are server
972 connection specific as it is convenient.
974 Changed the function silc_client_command_pending and
975 silc_client_command_pending_del and added new function
976 silc_client_command_pending_check. Removed the
977 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
980 * Added cmd_ident, current command identifier, to the client
981 connection context in lib/silcclient/client.h to keep track on
982 command identifiers used in command sending. Client's command reply
983 function handling now supports the mandatory command identifiers.
985 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
986 funtions in client to fully support pending command callbacks.
988 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
989 as one of the arguments to the application in the command reply
992 * NOTE: The FORWARDED flag is depracated. It used to be depracated
993 before first releasing SILC but came back. Now it is removed again
994 and should come back nomore. The FORWARDED flag was used only
995 by the JOINing procedure by forwarding the command packet to router.
996 Now, the JOINing procedure has been changed to more generic (due
997 to various router environment issues) and FORWARDED is not needed
998 anymore for anything. The protocol specification is yet to be
1001 Now, removed silc_server_packet_forward from server and the flag
1002 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1004 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1006 * Renamed NAMES command to USERS command. The NAMES was named that
1007 due to historical reasons. Now it is renamed. Also, rewrote
1008 parts of the USERS command. The nickname list is not sent anymore
1009 by the server. Only Client ID and mode lists are sent in the USERS
1010 command. Changed this also to the protocol specification.
1012 The client now resolves the names and stuff after it receives
1013 the USERS list from the server when joining to the channel.
1015 * WHOIS and IDENTIFY commands has been changed to support multiple
1016 Client ID's per command. One can now search for multiple users
1017 in the network by sending only one WHOIS or IDENTIFY command.
1018 Changed the code and the protocol specifications.
1020 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1021 uses silc_server_command_whois_parse to parse the request. */
1023 * If normal server, do not parse the WHOIS and IDENTIFY requests
1024 before sending it to the router. Saves some time.
1026 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1028 * Fixed JOIN command on client library. Wrong number of arguments
1029 used to crash the client.
1031 * Added silc_server_channel_has_global function to check whether
1032 channel has global users or not.
1034 * Added silc_server_channel_has_local function to check whether channel
1035 has locally connected clients on the channel.
1037 * The silc_server_remove_from_one_channel now checks whether the
1038 channel has global users or not after given client was removed from
1039 the channel. It also checks whether the channel has local clients
1040 on the channel anymore. If it does not have then the channel entry
1041 is removed as it is not needed anymore.
1043 * The silc_server_notify now checks on JOIN notify whether the joining
1044 client is one of locally connected or global. If it is global then
1045 the channel has now global users on the channel and that is marked
1046 to the channel entry. Also, it now saves the global client to
1047 global list who is joining and JOINs it to the channel. This is
1048 for normal server, that is.
1050 Changed silc_server_send_notify_on_channel,
1051 silc_server_packet_relay_to_channel and
1052 silc_server_packet_send_to_channel check if we are normal server
1053 and client has router set (ie. global client) do not send the
1054 message to that client, as it is already routed to our router.
1056 * Implemented LEAVE notify type handling in silc_server_notify
1059 * Tested LEAVE command in router environment successfully. Tested
1060 with two routers, two servers and two clients.
1064 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1066 * Implemented SIGNOFF notify type handling in silc_server_notify
1069 * silc_server_remove_id now removes the client entry from all channels
1070 it has joined and thusly sends SIGNOFF notify type.
1072 * Rewrote the NAMES list generation in server by removing two excess
1073 loops. The lists are created now inside one loop.
1075 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1077 * silc_server_remove_channel_user checks now also global list
1078 for channel and client.
1080 * silc_server_new_channel_user checks now both local and global
1081 list for channel and client. Fixed a bug in client id decoding.
1082 Used to decode wrong buffer.
1084 * silc_server_channel_message checks now both local and global
1085 list for channel entry.
1087 * Tested channel joining (hence JOIN) in router environment
1088 successfully. Tested with two routers, two servers and two
1091 * Tested channel message sending in router environment successfully.
1093 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1095 * Added silc_server_save_channel_key into server.[ch] to save the
1096 received channel key in Channel Key payload processing. It is
1097 also used in JOIN command reply handling.
1099 Equivalent function silc_client_save_channel_key added into
1100 client.[ch] into client library.
1102 * Changed JOIN command reply to send information whether the channel
1103 was created or not (is existing already) and the channel key
1104 payload. Changed protocol specs accordingly.
1106 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1107 the request was sent by ID and not by nickname. Crashed on
1110 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1112 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1113 now correctly save the received data.
1115 * silc_server_free_sock_user_data now notifies routers in the
1116 network about entities leaving the network.
1118 At the same time implemented functions silc_server_remove_id
1119 and silc_server_send_remove_id to receive and send REMOVE_ID
1120 packets. The packet is used to notify routers in the network
1121 about leaving entities. The ID removed will become invalid in
1124 * Added function silc_idlist_del_server into server. Removes and
1125 free's server entry from ID list.
1127 * silc_server_private_message function now checks, if we are router,
1128 that the destination ID really is valid ID, naturally.
1130 * In router when NEW_ID packet is received (for new client) the
1131 hash of the Client ID is saved in the ID Cache but the
1132 client->nickname is set to NULL, instead of putting the hash
1135 IDENTIFY command now also checks that client->nickname must be
1136 valid. If it is not if will request the data from the server who
1137 owns the client. Added new function
1138 silc_server_command_identify_check.
1140 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1141 to set the command to already allocated Command Payload.
1143 * Tested private message sending in router environment with two
1144 routers, two servers and two clients. Fixed minor bugs and now
1147 * Fixed segfault from client's NAMES command. Used to crash if
1150 * Forwarded packets must not be routed even if it is not destined
1151 to the receiver. Changed server code comply with this.
1153 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1155 * Added `require_reverse_mapping' boolean value to ServerParams
1156 structure. If TRUE (not default) the server will require that
1157 the connecting host has fully qualified domain name.
1159 If the reverse mapping is not required and hostname could not be
1160 found the IP address is used as hostname.
1162 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1164 * Implemented version string checking to both client and server.
1165 The check is incomplete currently due to the abnormal version
1166 strings used in development version of SILC.
1168 * Changed all command functions in server to use the new
1171 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1173 * Changed char *data to unsigned char *data in ID Cache system to
1174 support binary data as ID Cache data. Changed code to support
1175 binary data in lib/silccore/idcache.c.
1177 * Renamed silc_server_packet_relay_command_reply to
1178 silc_server_command_reply as it is normal packet receiving
1179 function. Rewrote the function to accept command replys for
1180 servers and not only for clients.
1182 * Mark remote router always as registered server if we are connecting
1183 to it. Otherwise, commands sent by the router to us are ignored.
1185 * All ID List find routines now returns the ID Cache Entry pointer
1186 as well if requested.
1188 * WHOIS command works now in router environment, tested with two
1189 routers, two servers and two clients.
1191 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1192 in router environment (as it is almost equivalent to WHOIS) but
1193 hasn't been tested thoroughly. Added new functions:
1195 silc_server_command_identify_parse
1196 silc_server_command_identify_send_reply
1197 silc_server_command_identify_from_client
1198 silc_server_command_identify_from_server
1200 * Disabled route cache adding because adding two different ID's with
1201 same IP replaces the old cache entry thus giving wrong route.
1202 The entry->router->connection is always the fastest route anyway
1203 so route cache may not be needed. Of course, new routes maybe
1204 established after receiving the ID when the entry->router->connection
1205 might not be anymore the most optimal.
1207 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1209 * Add route cache for received ID for fast routing.
1211 * Added silc_server_packet_route to route received packet on router
1212 that is not destined to us.
1214 * Renamed silc_server_get_route to silc_server_route_get.
1216 * Added id_string and id_string_len fields into SilcServer to
1217 include encoded ServerID for fast comparing without excess
1218 encoding of the ID's.
1220 * Cleaned up WHOIS command on server side. Added following static
1223 silc_server_command_whois_parse
1224 silc_server_command_whois_check
1225 silc_server_command_whois_send_reply
1226 silc_server_command_whois_from_client
1227 silc_server_command_whois_from_server
1229 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1230 arguments in command replies. All command functions should be
1231 updated to use this macro.
1233 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1235 * Minor typo fixes on command reply handling on server.
1237 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1239 * Added silc_server_command_add_to_channel internal routine to add
1240 the client to the channel after router has created the channel and
1241 sent command reply to the server.
1243 * Added generic silc_server_send_command to send any command from
1246 * Use static buffer with ID rendering instead of duplicating data.
1248 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1250 * Fixed a channel user mode bug when joining to a channel server gave
1251 everybody channel founder rights, oops.
1253 * We mark ourselves as the router of the incoming server connection
1254 if we are router ourselves. This way we can check in some packet
1255 sending functions whether it is locally connected server. For
1256 incoming router connections we put NULL.
1258 * For router sending packets locally means now always sending the
1259 packet cell wide; to local clients and local servers. For normal
1260 server sending packet locally means sending it to only local
1263 * Fixed the JOIN command to really work in router environment. If the
1264 channel is created it is always created by the router. Router is
1265 also responsible of making the initial joining to the channel,
1266 sending JOIN notify to the sending server and distributing
1267 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1268 does not exist server doesn't do anything else but forward the
1269 command to the router which performs everything.
1271 * Added silc_server_send_channel_key function to send the Channel Key
1274 * Added silc_server_create_channel_key to create new channel key. The
1275 channel key is now re-generated everytime someone joins or leaves
1276 a channel, as protocol dictates. Note: channel->key_len is the
1279 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1281 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1282 packet_receive.[ch] to separate packet sending and receiving
1283 routines. The server.[ch] now includes everything else including
1284 actual packet processing (writing and reading data) and other
1287 Renamed silc_server_private_message_send_internal to
1288 silc_server_send_private_message. The routine is still though
1289 used only to relay private messages as server does not send
1290 private messages itself.
1292 Renamed silc_server_new_channel to silc_server_create_new_channel
1293 and added new function sicl_server_new_channel that handles the
1294 incoming New Channel packet. Added also new sending function
1295 silc_server_send_new_channel to send New Channel Payload.
1297 * Added new function silc_server_notify to process incoming notify
1298 packet to the server/router. Server may then relay the notify
1299 to clients if needed.
1301 * Added new function silc_server_new_channel_user to process incoming
1302 New Channel User packet. Router will redistribute the packet and
1303 send JOIN notify to its local clients and locally connected servers
1304 if needed. Normal server will send JOIN notify to its local client
1305 on same channel when received this packet. Added also corresponding
1306 sending function silc_server_send_new_channel_user to sent the
1309 * Added boolean route argument to send_notif_to_channel and
1310 packet_send_to_channel functions to attempt to route the packet
1311 if it is TRUE and send only locally if it is FALSE.
1313 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1315 * silc_server_replace_id now broadcasts the received replace ID
1316 packet if it is not broadcast packet already. The router must
1317 broadcast to inform other routers about changed ID.
1319 * Added backpointer to server's router into SilcServer context in
1320 silcd/server_internal.h.
1322 * Fixed silc_server_packet_broadcast to send correct broadcast
1325 * The channel key is now distributed to the local client as soon
1326 as it is received from the router (in router environment) so that
1327 no other packet may be sent for the channel until client has
1330 * silc_server_remove_channel_user now broadcasts the received
1331 Remove Channel User packet if it is not broadcast packet already.
1332 The router must broadcast to inform other routers about removed
1335 * Added users field into SilcPacketContext that is a reference count
1336 of the context. One can increase the reference count by calling
1337 silc_packet_context_dup which is now changed to just increase the
1338 reference count instead of duplicating the data. The reference
1339 count is decresed by calling silc_packet_context_free that will
1340 free the data after the reference count hits zero.
1342 For now on the packet context and everything allocated into it
1343 (including the raw packet from network) must be freed by calling
1344 the new silc_packet_context_free function. Added also new function
1345 silc_packet_context_alloc that must be used now to allocate the
1346 context. This also means that if a routine is asynchronous from
1347 silc_[client/server]_packet_parse_type the packet context must
1348 be duplicated by calling silc_packet_context_dup. Otherwise it
1349 gets free'd after silc_[client/server]_packet_parse_type returns.
1350 Also, one must remember that if packet is duplicated then its
1351 reference count must be decresed by calling the free function as
1352 many times as it was duplicated.
1354 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1355 from both client and server.
1357 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1359 * Made joining to a channel working in router environment.
1361 * Cleaned up JOIN command on server side and create function
1362 silc_server_command_join_channel internal routine to make the
1365 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1367 * Changed silc_command_pending list to SilcDList. Also, added
1368 `ident' field to SilcServerCommandPending structure to identify
1369 the reply and to call correct callback.
1371 Added silc_server_command_pending_check function to replace the
1372 corresnponding macro. The silc_command_pending list is not
1375 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1376 to set identifier to previously allocated Command Payload. It
1377 is used to set identifier for command when resending Command
1380 * Added silc_command_payload_encode_payload to encode Command
1381 Payload buffer from SilcCommandPayload structure.
1383 * Added silc_argument_payload_encode_payload to encode Argument
1384 payload buffer from SilcArgumentPayload structure.
1386 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1388 * Changed WHOIS command to support router connection on server side.
1389 The whois request is always sent to router unless the server is
1390 standalone server. After server has received the reply from the
1391 router will it send the reply to the client.
1393 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1394 broadcast received broadcast packet. The function is used only
1395 by router. The broadcast packet is always sent to the router's
1398 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1399 render given ID to printable string, for log files for example.
1401 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1403 * Made basic router to router connections working. At least they
1404 can now connect to each other but nothing really works the way
1405 they are supposed - yet.
1407 * Added new initiator token to RouterConnection configuration
1408 file in silcd/serverconfig.[ch]. It is used to tell whether we
1409 are the initiator to the remote router or whether we'll expect
1410 the other end to connect.
1412 * Moved registering of listener task to silc_server_init, hence
1413 the server starts listenning as soon as it is run, even if it
1414 does not have connections to other routers. Let's see how well
1417 * Changed default connection retry timeouts for more suitable in
1420 * Removed cipher and such arguments from silc_idlist_add_client
1421 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1422 Added new function silc_idlist_add_data to add the keys and stuff
1425 * Added SilcIDListData structure and added it to SilcClientEntry
1426 and SilcServerEntry as their first field in the structure. This
1427 way we can explicitly cast the ID entries to the SilcIDListData
1428 structure and get common data for the entries. In past, we had
1429 to first check what type of connection it is and then cast it to
1430 correct ID entry type. Now, we can directly cast the opaque
1431 pointer to the SilcIDListData (no matter what ID entry it actually
1432 is) and get the data needed.
1434 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1436 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1437 in some circumstances even if threre were timeout tasks, though not
1438 IO tasks, but tasks anyway. Now fixed.
1440 * Defined SilcServerConnection structure to hold connection specific
1441 stuff about directly connected servers and routers. The definition
1442 is currently in silcd/server_internal.h. I thought about having
1443 a bit more important role fro this struct but for now it is used
1444 only when connecting to other server (or router actually).
1446 * Added connecting retry support in server when connecting to
1447 router(s). The retry feature implement exponential backoff
1448 algorithm. Also, added SilcServerParams structure to hold default
1449 parameters for server. For now, it include these retry settings
1450 and are hard coded. After server is moded to be as Silc Server
1451 Library this structure will be more important.
1453 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * Changed client librarys channel->clients table to SilcList and
1456 changed code accordingly.
1458 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1460 * Changed client's channel table to SilcList and changed code
1461 accordingly. Also changed SilcChannelClientEntry to include back-
1462 pointer to the channel so that client entry can use that structure
1463 as list as well and we have fast cross-reference to the channel.
1464 This change dramatically decreased the complexity of channel
1465 handling with client entry and vice versa (removed one extra
1466 loop when searching for channel entry from many functions).
1468 * Changed server->sim from table to SilcDList and changed code
1471 * NAMES command can now be used from user interface. It will show
1472 the user list on the channel, neatly.
1474 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1475 Code now saves realname of the user if it becomes available.
1477 * Renamed configure.in to configure.in.pre and made ./prepare
1478 script to automatically add correct version string to
1479 configure.in which it creates from configure.in.pre.
1481 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1483 * NAMES command reply now shows users mode with the nickname when
1486 * Moved silc_client_ch[u]mode[_char] functions from
1487 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1488 place sucks, they are utility functions and should be in some
1491 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1493 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1496 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1500 * Added TRQ (efficient deque and list library) into lib/trq. This is
1501 a very good list library that is currently used in the SILC. Defined
1502 SilcList API over the library because I didn't like the API very
1503 much. See lib/trq/silclist.h for the API and examples of how to
1504 use the API. Fixed various places in the code to use the new
1505 SilcList API. The SilcList is meant for lists that has a structure
1506 already defined as a list. It is not suitable to add just some
1507 context to the list (in TRQ, the context is the list actually).
1509 So, I defined SilcDList that can be used for the purpose where
1510 predefined list structure does not exit. This can be used as
1511 such list. Now some context just can be added to the SilcDList.
1512 Currently this list is not used in the SILC just yet, though there
1513 are a lot places where this can replace dynamically allocated
1514 tables and I will fix these places, later, to use SilcDList.
1515 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1516 and use TRQ internally).
1518 Also fixed some annoying warning messages that the original TRQ
1519 code generated. Also minor changes to TRQ's Makefile.in.
1521 * Added support for querying by Client ID to both WHOIS and
1522 IDENTIFY commands into server, as required by the protocol.
1524 * Removed method function pointers from SilcBuffer structure. They
1525 weren't used to anything and just increased the context size for
1526 no good reason. This change also made silc_buffer_alloc and
1527 silc_buffer_free functions inline functions.
1529 * Disabled command flooding detection support until it's fixed so
1530 that it accepts commands in but does not execute them more than once
1533 * Added silc_net_localhost(), to return local hostname, into
1534 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1535 that must be initialized before calling silc_client_init.
1537 * Added new function: silc_server_send_notify_on_channels to send
1538 notify messages to all channels client has joined. It is assured
1539 that the message is sent only once per client.
1541 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1542 lib/silcutil/silcutil.[ch] as silc_format function. The new
1543 function is generic and is used by server as well, not only by
1544 the logging routines.
1546 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1547 the provided version string was not acceptable. Added new function:
1548 silc_ske_check_version into lib/silcske/silcske.h. The function
1549 must be implemented by the application (client or server) and it
1550 does not reside in the SKE library. The function checks the version
1551 string remote end sent.
1553 * Added back pointers (to opaque context and to SilcSocketConnection)
1554 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1556 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1557 duplicate packet context structure.
1559 * Changed `notify' client operation to send same arguments as client
1560 receives from server except for ID's. ID's are mapped to correct
1561 ID entry and that is returned. Also, if channel entry is not sent
1562 by server but the notify is for channel the channel entry is sent
1563 to application (otherwise application doesn't know that it is for
1564 channel (library gets it from packet's Destination ID)).
1566 * Added silc_client_remove_from_channels into client library to
1567 remove a client from all channels it has joined to. Used when
1568 received SIGNOFF notify from server. Added also new function
1569 silc_client_replace_from_channels to replace old ID entry with
1570 new ID entry on all channels. Used when received NICK_CHANGE
1573 * Fixed ID Cache list handling in silc_idlist_get_client in
1574 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1575 to get (or query) client by ID.
1577 * Updated TODO list.
1579 * Added connection authentication status message defined by the
1580 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1581 support for these into the code in client and server side.
1583 * Added generic function silc_client_send_command to send any command
1584 with variable argument list. Application should use this function
1585 to send commands if the command functions provided by the library
1586 does not suite for the application's user interface needs.
1588 * Added new `failure' client operation. Application is notified about
1589 received failure packet if client is executing a protocol. In this
1590 case the protocol's execution has failed.
1592 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1593 is required by the protocol.
1595 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1596 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1599 * Added status flag to SilcSKE object to indicate realtime status
1600 of the SKE protocol.
1602 * Application receives now exactly same command reply arguments as
1603 the library receives from server. However, if ID is received the
1604 corresponding ID entry is returned to the application (eg. Client
1605 ID is mapped to correct SilcClientEntry entry and that is returned).
1606 Changed command_reply client operation due to this change.
1608 * Changed all ID's in commands and in command replys as ID Payloads.
1609 Change affected both client and server side codes.
1611 All ID's sent in SILC network (with execption of ID's in SILC
1612 Packet header) are sent in ID Payload to support variable length
1615 * Server now notifies nick changes and notifies all clients on
1616 the channels about the new nickname (about the new Client ID,
1619 * Implemented CMODE command to change channel modes. Supports all
1620 channel modes defined by the protocol specs except ban and invite
1621 lists. (Also, private channel key mode is supported but support for
1622 setting private channel key in client is missing, thus, this mode
1623 has no effect on client side (except that server requires that the
1624 client uses private channel key and normal channel traffic does not
1627 Also, invite mode works per se, but INVITE command does not work
1628 yet correctly, so you can set channel as invite only channel but
1629 inviting clients to the channel does not work (it is yet to be
1630 thought what's the best way to do it).
1632 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1633 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1634 Implemented CUMODE command to change user's mode on the channel.
1635 Supports all modes defined by the protocol specs.
1637 * Added NAMES command reply to return users modes on the channel.
1639 * Removed unnecessary and slow ciphers from lib/silccrypt.
1641 * Set SO_KEEPALIVE option to connection sockets by default.
1643 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1645 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1646 redefined the Notify Payload into protocol specs.
1648 * Added silc_id_payload_parse_id to get ID directly from raw
1651 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1653 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1654 accept searching by Client ID as well.
1656 * Added support for LEAVE and SIGNOFF notify types in client library.
1658 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1659 to parse ID Payload from raw data.
1661 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1663 * Added flags parameter into silc_ske_assemble_security_properties
1664 function in lib/silcske/silcske.[ch].
1666 * Changed notify client operation to fit better for notify messages
1667 sent by server. The notify payload received from server is now
1668 passed to the application (after parsing it to SilcNotifyPayload).
1669 It is application's responsibility to retrieve the arguments
1670 from the payload and show the message the way it wants. The message
1671 sent by server is implementation specific.
1673 * Changed public keys to comply with the protocol specification.
1674 Old public keys are not supported anymore and are not compatible.
1676 * Removed nickname from Channel Payload as the latest draft removed
1677 it. The client must resolve the nickname from the NAMES command
1678 reply received when it joined the channel.
1680 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1682 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1684 * Fixed some errors in protocol specification drafts.
1686 * Created lib/silccore/silcnotify.c to implement Notify Payload
1687 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1688 generic payloads described by protocol specifications. The file
1689 includes implementations for ID Payload and Argument Payload.
1691 * Changed Command Payload implementation to use the new Argument
1692 Payload. Changed command_xxxx_payload to command_payload_xxxx
1693 to comply with SILC coding conventions.
1695 * Added suppport for Argument Payload handling in Notify Payload
1696 implementation as protocol requires it. Added the new support
1697 into server and client lib as well.
1699 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1701 * Added support for multiple nicknames on same channel. [n] is
1702 added locally to the nickname if there are more than one same
1703 nicknames on the channel.
1705 * Server now sends all nicknames that matched WHOIS request.
1706 Client also shows the list received from server.
1708 * Added TOPIC command to client side. User can now set and show
1709 current topic on channel.
1711 * Added MOTD command to client and server. Also, server sends the
1712 motd when client connects to the server.
1714 * Changed version strings to comply ISO 8601.
1716 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1718 * Fixed protocol error handling in client library. It should now
1719 cope even if the SKE fails for some reason.
1721 * Made new protocol specification drafts for submitting to IETF.
1723 * Implemented TOPIC command to server in silcd/command.c.
1725 * Added two new notify types into lib/silccore/silcnotify.h:
1726 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1727 notify nickname change and topic setting/change on a channel.
1729 * API change of command_reply operation in client library. The
1730 application gets now the status type received from server as well.
1732 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1734 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1736 * Cras fixed and optimized the packet handling even further and
1737 it should work now. Minor change to the prototype of function
1738 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1740 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1742 * Added new function into lib/silcutil/silcschedule.[ch]:
1743 silc_schedule_with_fd to select() a specified fd. The function
1744 returns after timeout expires or data arrives or goes. The
1745 function is used by packet routines to wait that all data is
1746 received from network.
1748 * Fixed data reading from network in lib/silccore/silcpacket.c.
1749 The code now assures that all data is read from the fd and then
1750 continues packet processing. This was a bug fix since the code
1751 used to drop some data in some circumstances.
1753 * Added new function into lib/silcclient/client.[ch]:
1754 silc_client_start_key_exchange to start key exchange after
1755 connection has been established to server. The code internally
1756 now uses this funtion but its main purpose was to provide it
1757 for applications that perform their own connecting. After
1758 application has created a connection it merely calls this
1759 function to start the key exchange between client and server.
1760 The library takes care of everything else after that.
1762 Updated also lib/silcclient/README to explain the usage of
1765 * Do not send to application information that connection has
1766 been established. Application gets notified it by connect
1769 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1771 * Applied cras's patch to add silc_schedule_one function. The
1772 function runs scheduler once and returns.
1774 * Fixed the scheduler after cras messed it up. The timeout
1775 handling works now as it's supposed to work.
1777 * Added into lib/silccore/ silcnotify.h to include notify
1778 message types support. Changed silc_server_send_notify*
1779 functions, in server.[ch], to support those new notify types.
1780 Added the support for the notify types into client library,
1781 as well. Added new notify client operation into ops.h in
1784 * Changed silc_server_packet_send_to_channel to send normal
1785 packets instead of just channel message packets. The function
1786 is now used to send the notify packets to channels. It is not
1787 used to send channel message packets anymore, as server never
1790 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1791 va_arg()s as it seems to require it nowadays. I guess, if SILC
1792 is compiled with older va_arg() the new code should work anyway.
1794 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1796 * Splitted core library. Core library (lib/silccore) includes
1797 now only SILC protocol specific core (and common) components.
1798 Created new utility library (lib/silcutil) that includes more
1799 generic purpose stuff. The stuff for util library was taken
1800 from the old core library. This was minor and easy split.
1802 * Created SILC Client Library (lib/silcclient) that includes
1803 implementation of the SILC client without user interface. This
1804 was major move from silc/ directory. The code has been changed
1805 so that it is transparent towards the user interface. The
1806 silc/ directory includes now the same user interface as before
1807 and it uses the new client library. Read lib/silcclient/README.
1808 Basicly, the client library performs everything else related
1809 to SILC except user interface handling. Also, configuration
1810 files are considered to be part of user interface and library
1811 does not handle them.
1813 This change also changed a lot of structures, function naming etc.
1814 Most important change was that SilcClientWindow object was
1815 renamed to SilcClientConnection in the client library. Created
1816 also new file lib/silcclient/ops.h. Also added new files
1817 silc/local_command.[ch] and silc/client_ops.[ch].
1819 All these changes were made to make it easier for user interface
1820 designers to create what ever user interface for the SILC client
1823 It is also expected that the server will be moved to lib
1824 directory as well and SILC Server Library will be created;
1825 sometimes in the future.
1827 * Removed Local commands from lib/silccore/silccommand.h as
1828 they are application specific and new client library does not
1829 handle any of those anymore.
1831 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1832 old client implementation in silc/.
1834 * Added support for callback functions in SILC_LOG_* macros.
1835 Application can now set its own callbacks that will be called
1836 instead of using the default functions that will always print
1837 the debug messages to stderr (or stdout). Also, debugging can
1838 now be disabled by setting silc_debug to FALSE and re-enabled by
1839 setting it to TRUE. Note, that logging will still work even
1840 if debugging is disabled.
1842 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1843 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1844 silc_log_reset_debug_callbacks.
1846 * To enable debugging in silc client one must give now -d
1847 option on command line.
1849 * Changed silc_schedule_init to automatically allocate task queues
1850 if they are not allocated before calling it.
1852 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1854 * Added GMP 3.1 into math library.
1856 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1858 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1859 a channel in SILC network. The packet is used by servers and
1860 routers to notify other routers that user has left a channel.
1861 This little feature was missing until now. Added the feature
1862 to protocol specification as well.
1864 Added functions: silc_server_send_remove_channel_user and
1865 silc_server_remove_channel_user into server.[ch].
1867 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1868 lib/silccore/silcpacket.h. However, they are not implemented
1871 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1873 * Fixed joining to a channel and sending channel messages
1874 between server and router. The channel message sending should
1875 now work inside a cell.
1877 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1879 * Fixed the private message sending between server and router.
1880 The private message sending should now work inside a cell.
1882 * Added silc_server_replace_id into server.[ch] to replace
1883 existing ID in the SILC network.
1885 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1886 and silc_idlist_replace_server_id into idlist.[ch] in server.
1888 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1890 * Fixed the server to server connections. Server can again now
1891 connect to router. Router to router connections probably does
1894 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1896 * Added dynamic protocol registering support. Now protocols can
1897 registered and unregistered on the fly. Patch by cras.
1899 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1901 * Added lib/contrib directory to hold routines that some platforms
1902 don't have but are needed by SILC.
1904 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1905 into lin/contrib to provide getopt() and getopt_long() for
1906 those who don't have it.
1908 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1910 * Added AWAY command to client. When away message is set and
1911 client receives a private message packet the client automatically
1912 replies to the sender with the away message.
1914 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1915 bug seemed to be the cause of recent problems when compiling
1918 * Added version detection support to SKE protocol specification
1919 and added the new changes to the SKE implementation as well.
1920 There were other minor changes in the SKE protocol as well.
1922 Many changes in lib/silcske/silcske.[ch] and in
1923 lib/silcske/payload.[ch].
1925 * Added ^U functionality, clear input line. Patch from cras.
1927 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1929 * Mainly small bugfixes on core library. Fixed some debugging
1930 logging and buffer overflow in silclog.c.
1932 * Updated config.sub and config.guess on the distribution tree.
1934 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1936 * Added command lagging support in server. Client may execute
1937 commands now only once in two seconds.
1939 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1941 * Optimized packet reception. MAC computation and checking is now
1942 also more optimized. A lot previously duplicated code is now
1943 used as generic by both client and server.
1945 * Fixed key pair generation in clientutil.c
1947 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1949 * Added into lib/silccore/silcbufutil.[ch] new function;
1950 silc_buffer_realloc.
1952 * Moved generic packet sending/encryption functions to
1953 lib/silccore/silcpacket.[ch] from client and server. Some
1954 rewriting of the functions.
1956 * Moved all generic packet reception/decryption functions to
1957 lib/silccore/silcpacket.[ch] from client and server. The
1958 packet processing is now much cleaner in both client and server.
1959 These were major changes in both client and server.
1961 * Created many common functions in server to do packet sending.
1962 Previously code were duplicated a lot, this has been removed
1965 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1967 * Rewrote major parts of the ID cache system. Don't know
1968 whether it is better now or not but at least the API is more
1971 * Major rewrite on ID cache stuff on client because of the ID
1972 cache API changes. Added idlist.c to client.
1974 * Also major rewrite on ID cache stuff on server as well.
1975 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1976 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1977 in hand, instead they are all put into the ID cache system now.
1978 All server_idlist_* routines uses ID cache now instead of
1979 traversing its own lists (those lists does not exist anymore).
1980 SilcIDList though still exists. Also, SilcXXXEntry's are
1983 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1985 * Finally made the SKE implementation compliant to the protocol
1986 specification. All mp integers are now binary encoded as
1987 opposed being HEX encoded.
1989 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
1992 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
1993 functions: silc_[encode/decode]_pem. Also added function
1994 silc_encode_pem_file to PEM encode with newlines ('\n') for
1997 * SILC public keys are now encoded either PEM or binary. Same
1998 option is for private keys as well. By default private keys
1999 are binary encoded and public keys PEM encoded. Silly HEX
2000 encoding were removed.
2002 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2003 function to create fingerprints.
2005 * Fixed a bug in SHA1; does not change the original data anymore.
2007 * Partly implemented INFO command on client and server side.
2008 Fixed CLEAR command. Changes to SERVER command; show current
2009 server(s) when giving command without arguments. Added
2010 VERSION command to client.
2012 * Added check to server that unregistered connections cannot
2013 execute commands (unless it is specificly allowed).
2015 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2017 * Fixed screen refresh.
2019 * Fixed channel joining bug from client. On some circumstances
2020 client tried to join to a channel it had already joined.
2022 * Added public key verification process into client's protocol.c.
2023 The client now verifies the public key from user and saves
2024 it into ~./silc/serverkeys/ directory.
2026 Added into: clientutil.[ch]: silc_client_verify_server_key.
2028 * Changed SKE protocol's silc_ske_initiator_finish function
2029 to accept callback function that verifies the received public
2030 key. Removed old silc_ske_verify_public_key function.
2032 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2034 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2035 silc_pkcs_private_key[_data]_set.
2037 * Made the password and public authentication more cleaner in
2038 server's protocol.c.
2040 * Removed historic and obsolete protocol `channel_auth' from
2041 both client and server.
2043 * Removed wrong way of sending command status messages from
2044 server to client in server's command.c. The old way violated
2045 protocol specification.
2047 Changes to silccore/silccommand.[ch]: removed
2048 silc_command_encode_status_payload -> not needed anymore,
2049 changed silc_command_encode_payload_va to accept extra
2050 argument on variable argument list. The argument type must
2051 now be provided to the function. Also, added new function:
2052 silc_command_encode_reply_payload_va which is same as
2053 normal command_encode_payload_va except command status type
2054 is provided as extra argument.
2056 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2058 * Added ~./silc directory handling. The directory includes the
2059 public and private keys for the client.
2061 Added silc_client_check_silc_dir, silc_client_create_identifier
2062 and silc_client_load_keys.
2064 * Implemented SILC protocol compliant public key. Added public
2065 and private key saving to and loading from files.
2067 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2068 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2069 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2070 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2071 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2073 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2074 silc_pkcs_load_[public/private]_key.
2076 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2078 * Added silc_server_get_route (route.[ch]) to get connection
2079 data for the fastest route for given ID.
2081 * Implemented INVITE command on client and server. The command
2082 were re-defined in the SILC Protocol Specification and the
2083 implementation now complies with the specification.
2085 * Implemented PING command on client and server.
2087 * Implemented NAMES command on client and server. The server side
2088 supports currently only normal server not router server yet.
2089 Some changes to NAMES definition in SILC protocol specification.
2091 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2093 * Implemented LEAVE command on client and server.
2095 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2096 again. This change was made to the protocol as well. Server
2097 should not violate the protocol specification anymore.
2099 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2101 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2102 was tested. SOCKS4 was not but should work anyway.
