+Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added new SILC_CF_LAG_STRICT command flag that strictly forces
+ that the command may be executed only once in (about) 2 seconds.
+ The old SILC_CF_LAG flag is same but allows command bursts up
+ to five before limiting.
+
+ Added the support for CF_LAG and CF_LAG_STRICT flags to the
+ server code. Various commands now includes the CF_LAG_STRICT
+ flag to disallow any kind of miss-use of the command.
+
+Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Changed the format of AdminConnection configuration section
+ in the server. Added username of the admin to the format.
+ Affected files silcd/serverconfig.[ch].
+
+ Added silc_server_config_find_admin into silcd/serverconfig.[ch]
+ to return admin configuration data by host, username and/or
+ nickname.
+
+Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Implemented WHOWAS command to the server. Added the functions:
+
+ silc_server_command_whowas_parse,
+ silc_server_command_whowas_send_reply,
+ silc_server_command_whowas_from_client and
+ silc_server_command_whowas_from_server
+
+ * Added <Client ID> argument to the WHOWAS command reply. Updated
+ the protocol specs accordingly.
+
+ * Implemented WHOWAS command and command_reply to the client
+ library.
+
+ Implemented the WHOWAS printing on the user interface.
+
+Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added new argument to the WHOWAS command reply, the real name.
+ It is an optional argument. Updated the protocol specs.
+
+ * Added SilcIDCacheDestructor callback that is registered when
+ the SilcIDCache is allocated. The callback is called when
+ an cache entry in the ID Cache expires, or is purged from the
+ cache. Added into lib/silccore/idcache.[ch].
+
+ Added silc_idlist_client_destructor to the silcd/idlist.[ch]
+ to destruct the client entries when the cache entry expires.
+ Other ID Cache's in server and in the client library ignores
+ the destructor.
+
+ * If the ID Cache entry's `expire' field is zero then the entry
+ never expires. Added boolean `expire' argument to the
+ silc_idcache_add function in the lib/silccore/idcache.[ch].
+ If it is TRUE the default expiry value is used.
+
+ * Added silc_server_free_client_data_timeout that is registered
+ when client disconnects. By default for 5 minutes we preserve
+ the client entry for history - for WHOWAS command.
+
+Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added support to the server to enforce that commands are not
+ executed more than once in 2 seconds. If server receives
+ commands from client more frequently, timeout is registered
+ to process the commands. Affected file silcd/command.c.
+ Added new function silc_server_command_process_timeout.
+
+ * Changed NICK_NOTIFY handling in client library to check that
+ if the client's nickname was changed, so there is no need to
+ resolve anything from the server.
+
+ * Removed error printing from the WHOIS and IDENTIFY commands.
+ If error occurs then it is ignored silently in the client library.
+ The application, however, may map the received error to
+ human readable error string. The application currently maps
+ the NO_SUCH_NICKNAME error to string.
+
+ * Made the command status message public to the application. Moved
+ them from lib/silcclient/command_reply.c to
+ lib/silcclient/command_reply.h. The application can map the
+ received command status to the string with the
+ silc_client_command_status_message function.
+
+ * Added check to the server to check that client's ID is same
+ as the Source ID in the packet the client sent. They must
+ match.
+
+Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added dist-bzip hook to the Makefile.am to make bzip2
+ compressed distributions.
+
+Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Server now enforces the maximum length for the nickname and
+ the channel as protocol specification dictates. 128 bytes for
+ nickname and 256 bytes for channel name.
+
+ * Moved the WHOIS printing to the application. The client libary
+ does not print out the WHOIS information anymore, the application
+ must do it. Renamed silc_client_command_reply_whois_print to
+ the silc_client_command_reply_whois_save.
+
+ The client's idle time is also sent to the application now, and
+ the idle is shown on screen.
+
+ * Added silc_client_command_reply_identify_save to save the
+ received IDENTIFY entries.
+
+ * Do not check for channel private keys in message sending and
+ reception if the channel does not have the PRIVKEY mode set.
+ Affected file lib/silclient/client_channel.c.
+
+Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
+ just surfaced after chaning the JOIN procedure.
+
+Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added silc_client_get_clients_by_list to get client entries
+ from Client ID list, that is returned for example by JOIN
+ and USERS command replies. The application should use this
+ function for example when JOIN command reply is received to
+ resolve the clients already on the channel (library does not
+ do that anymore as USERS command reply is not used in the JOIN
+ procedure anymore). Affected files lib/silcclient/silcapi.h and
+ lib/silcclient/idlist.c.
+
+ * JOIN command reply and USERS command reply returns now SilcBuffer
+ pointers instead of unsigned char pointers when returning
+ the client list and mode list.
+
+ * Added <Client ID> argument to the JOIN command reply, mainly
+ for the server to identify for which client the command was
+ originally sent. Updated protocol specs accordingly.
+
+ * Added SilcDlist private_key pointer to the SilcChannelEntry
+ in the client to support the channel private keys. Affected
+ file is lib/silcclient/idlist.h.
+
+ * Added SilcChannelPrivateKey argument to the function
+ silc_client_send_channel_message so that application can choose
+ to use specific private ke if it wants to. If it is not provided,
+ the normal channel key is used, unless private keys are set.
+ In this case the first (key that was added first) is used
+ as the encryption key.
+
+ * Implemented the support for channel private key handling.
+ Implemented the following functions:
+
+ silc_client_add_channel_private_key,
+ silc_client_del_channel_private_keys,
+ silc_client_del_channel_private_key,
+ silc_client_list_channel_private_keys and
+ silc_client_free_channel_private_keys
+
+ Affected file lib/silcclient/client_channel.c.
+
+ * Added the support for the private keys in the channel message
+ sending and encryption and in the message reception and
+ decryption. Affected funtions are
+ silc_client_send_channel_message and silc_client_channel_message.
+
+Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added SKE's key verify callback to the client library's
+ KE protocol context. Affected files lib/silcclient/protocol.[ch].
+
+ * Removed the statement that server (or router) must send USERS
+ command reply when joining to the channel so that the client
+ knows who are on the channel. Instead, the client list and
+ client's mode list is now sent in the JOIN command reply to the
+ client who joined channel. This is better solution.
+
+ * Added function silc_server_get_users_on_channel and function
+ silc_server_save_users_on_channel to the silcd/server.[ch].
+
+ * Removed function silc_server_command_send_users from the
+ silcd/command.c.
+
+ * Do not show topic on the client library anymore. The topic is
+ sent in the command reply notify to the application and the
+ application must show the topic now.
+
+Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added client searching by nickname hash into the IDENTIFY and
+ WHOIS commands in the server as they were clearly missing from
+ them. Affected file is silcd/command.c.
+
+ * Fixed a bug in private message receiving in the client library.
+ The remote ID was freed and it wasn't supposed, now it is
+ duplicated.
+
+Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Minor fix to the channel payload; allocate the data area, as it
+ needs to be of specific length.
+
+ * If the key agreement port is zero then the operating
+ system will define the bound port. Affected files are
+ lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
+
+ * Added new function silc_channel_payload_decrypt into the file
+ lib/silccore/silcchannel.[ch].
+
+ * Moved the channel message etc, check from silc_packet_decrypt
+ to applications. The library calls now a generic
+ SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
+ when the packet is either normal or special. This was done to
+ allow more wide range of checking that was not allowed when
+ the code was in library. Now applications can do virtually any
+ checks to the packet and return to the library the decision how
+ the packet should be processed. Affected files are
+ lib/silccore/silcpacket.[ch].
+
+ Added silc_server_packet_decrypt_check to the server and
+ silc_client_packet_decrypt_check to the client library.
+
+ * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
+ to send with specified source and destination information.
+
+ * Channel message delivery between routers was broken after the
+ channel key distribution was fixed earlier. The channel key
+ was used be to distributed to other routers as well which is not
+ allowed by the protocol. Now this is fixed and channel keys
+ really are cell specific and the channel message delivery between
+ routers comply with the protocol specification.
+
+ * Fixed various commands in server to check also the global list
+ for the channel entry and not just the local list. The affected
+ file silcd/command.c.
+
+Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added assert()s to buffer formatting and unformatting routines
+ to assert (if --enable-debug) when error occurs. Affected
+ file: lib/silcutil/silcbuffmt.c.
+
+ * Changed to auto-reconnect to check whether the remote host is
+ router and register the re-connect timeout if it is. It used
+ to check that whether we are normal server, but router must do
+ auto-reconnect with another router as well. Affected file
+ silcd/server.c.
+
+ * Removed the [<key len>] option from CMODE command as the cipher
+ name decides the key length, nowadays. See the defined ciphers
+ from the protocol specification.
+
+ * Added [<hmac>] option to the CMODE command to define the HMAC
+ for the channel. Added SILC_CMODE_HMAC channel mode.
+
+ * Added [<hmac>] option for the JOIN command so that user can
+ select which HMAC is used to compute the MACs of the channel
+ messages.
+
+ * Added Hmac field to the Channel Message Payload. The integrity
+ of plaintext channel messages are now protected by computing
+ MAC of the message and attaching the MAC to the payload. The
+ MAC is encrypted. Now, it is clear that this causes some
+ overhead to the size of the packet but rationale for this is that
+ now the receiver can verify whether the channel message decrypted
+ correctly and also when private keys are set for the channel the
+ receiver can decrypt the packet with several keys and check from
+ the MAC which key decrypted the message correctly.
+
+ * Added silc_cipher_encrypt and silc_cipher_decrypt into the
+ lib/silccrypt/silccipher.[ch].
+
+ * Added silc_hash_len to return the digest length into the
+ lib/silcrypt/silchash.[ch].
+
+ * Rewrote parts of Silc Channel Payload interface in the
+ lib/silccore/silcchannel.[ch]. The encode function now also
+ encrypts the packet and parse function decrypts it.
+
+Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Fixed a minor formatting bug in the SKE's key material processing.
+ It actually might have processed the keys wrong way resulting
+ into wrong keys.
+
+ * Redefined the mandatory HMAC algorithms and added new algorithms.
+ Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
+ and hmac-md5 truncated to 96 bits. The mandatory is now
+ hmac-sha1-96. Rest are optional (including the one that used
+ to be mandatory). Rationale for this is that the truncated HMAC
+ length is sufficient from security point of view and can actually
+ make the attack against the HMAC harder. Also, the truncated
+ HMAC causes less overhead to the packets. See the RFC2104 for
+ more information.
+
+ * Added new [hmac] configuration section. The SKE used to use
+ the hash names (md5 and sha1) in the SKE proposal as HMCAS which
+ is of course wrong. The official names that must be proposed in
+ the SKE are the ones defined in the protocol specification
+ (hmac-sha1-96 for example). The user can configure any hmac
+ using any hash function configured in the [hash] section. At
+ least, the mandatory must be configured.
+
+ Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
+
+ * Added HMAC list to the SKE proposal list. It has now both
+ hash algorithm list and HMAC list. This makes the protocol
+ incompatible with previous versions. The SKE now seems to work
+ the way it is supposed to work, for the first time actually.
+
+ * Defined plain Hash algorithms to the protocol specification.
+ Added sha1 and md5.
+
+Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Implemented support for key agreement packets into the server.
+ Added functions silc_server_key_agreement and
+ silc_server_send_key_agreement. Other than these functions,
+ server has nothing to do with this packet.
+
+ * Added support for private message key packets into the server.
+ Added functions silc_server_private_message_key and
+ silc_server_send_private_message_key.
+
+ * Updated TODO.
+
+ * Changed the silc_[client|server]_protocol_ke_set_keys to be
+ called in the protocol's final callback instead in the END
+ protocol state. This makes a little more sense and in the same
+ time in client we can use the same protocol routines for normal
+ key exchange and to key agreement packet handling as well.
+
+ * Added to both client's and server's KE protocol context the
+ SilcSKEKeyMaterial pointer to save the key material. We will
+ bring the key material to the protocol's final callback by doing
+ this. The final callback must free the key material.
+
+ * Added SKE's packet_send callback into client's KE protocol
+ context so that the caller can choose what packet sending function
+ is used. This way we can use different packet sending when
+ doing normal SKE when doing key agreement packet handling (in
+ the key agreement packet handling we do not want to encrypt
+ the packets).
+
+ * Implemented the responder side of the key agreement routines
+ in the client. The client can now bind to specified port and
+ accept incoming key negotiation. The key material is passed
+ to the application after the protocol is over.
+
+ * Implemented the processing of incoming Key Agreement packet
+ in the client. Added function silc_client_key_agreement to
+ process the packet.
+
+ * Implemented the intiator side of the key agreement routines
+ in the client. The client can now initiate key agreement with
+ another remote client. The key material is passed to the
+ application after the protocol is over.
+
+ * Created client_keyagr.c to include all the key agreement
+ routines.
+
+ * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
+ SILC_TASK_CALLBACK except that it is not static.
+
+ * Created client_notify.c and moved the Notify packet handling
+ from the client.[ch] into that file.
+
+ * Created client_prvmsg.c and moved all private message and
+ private message key routines from the client.[ch] into that file.
+
+ * Create client_channel.c and moved all channel message and
+ channel private key routines from the client.[ch] into that file.
+
+ * Changed silc_client_get_client_by_id_resolve to resolve with
+ WHOIS command instead of IDENTIFY command, in the file
+ lib/silclient/idlist.c.
+
+Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Implemented the SKE's responder side to the Client library.
+
+ * When FAILURE is received to the protocol do not trust it
+ blindly. Register a timeout to wait whether the remote closes
+ the connection as it should do it, only after that process the
+ actual failure. This was changed to both client and server.
+
+ * Added client_internal.h to include some of the structures
+ there instead of client.h in lib/silcclient/.
+
+ * Added function silc_task_unregister_by_callback to unregister
+ timeouts by the callback function.
+
+Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Some "Incomplete WHOIS info" errors has been appearing on the
+ log files. Took away the entry->userinfo check from WHOIS
+ reply sending. The entry->userinfo is now " " if client did not
+ provide one. I thought this was fixed earlier but something
+ is wrong still. Let's see if the error still appears.
+
+Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Fixed a minor bug in the login when the channel key is
+ re-generated in the server. It used to generate the key in
+ wrong order and thus caused problems in the channel traffic.
+
+ * Fixed a minor bug in channel key distsribution after
+ KICK command. The key was not sent to the router even though
+ it should've been.
+
+Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added silc_ske_process_key_material_data as generic routine
+ to process any key material as the SILC protocol dictates. The
+ function is used by the actual SKE library but can be used by
+ applications as well. This relates to the private message keys
+ and the channel private keys since they must be processed the
+ same way the normal SILC session keys. The protocol dictates
+ this. Affected files: lib/silcske/silcske.[ch].
+
+ Added also silc_ske_free_key_material to free the
+ SilcSKEKeyMaterial structure.
+
+ * Defined silc_cipher_set_key function to set the key for
+ cipher without using the object's method function. The affected
+ files: lib/silccrypt/silccipher.[ch].
+
+ * Implemented silc silc_client_add_private_message_key,
+ silc_client_add_private_message_key_ske,
+ silc_client_del_private_message_key,
+ silc_client_list_private_message_keys and
+ silc_client_free_private_message_keys functions in the
+ client library.
+
+ Added functions silc_client_send_private_message_key to send
+ the Private Message Key payload and silc_client_private_message_key
+ to handle incoming Private Message Key payload.
+
+ * Added Cipher field to the Private Message Key payload to set
+ the cipher to be used. If ignored, the default cipher defined
+ in the SILC protocol (aes-256-cbc) is used.
+
+Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Removed lib/silcclient/ops.h file.
+
+ Redefined parts of the SILC Client Library API. Created new
+ file silcapi.h that deprecates the ops.h file and defines the
+ published Client Library API. Defined also private message key
+ API and channel private key API into the file.
+
+ This is the file that the application must include from the
+ SILC Client Library. Other files need not be included by
+ the application anymore.
+
+ * Added new key_agreement client operation callback and also
+ defined the Key Agreement library API for the application.
+
+Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
+ is used by clients to request key negotiation between another
+ client in the SILC network. If the negotiation is started it
+ is performed using the SKE protocol. The result of the
+ negotiation, the secret key material, can be used for example
+ as private message key.
+
+ Implemented the Key Agreement payload into the files
+ lib/silccore/silauth.[ch].
+
+Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Redefined ciphers for the SILC protocol. Added some new ciphers
+ and defined the key lengths for the algorithms. Changed the
+ code accordingly. The default key length is now 256 bits.
+
+ * Fixed SKE key distribution function silc_ske_process_key_material
+ when the key length is more than 128 bits. The default key
+ length in SILC is now 256 bits.
+
+ * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
+ to indicate unsupported algorithm.
+
+ * Renamed rijndael.c to aes.c and all functions as well.
+
+ * Fixed a long standing channel key setting bug in client library.
+ Weird that it has never surfaced before.
+
+ * Fixed bug in channel deletion. If the entire channel is removed
+ then it must also delete the references of the channel entry
+ from the client's channel list as the client's channel entry and
+ the channel's client entry share same memory.
+
+Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Implemented CONNECT and SHUTDOWN commands in the client.
+
+ * Implemented CLOSE command to the client.
+
+ * Added the function silc_idlist_find_server_by_name into the
+ files silcd/idlist.[ch].
+
+ Added the function silc_idlist_find_server_by_conn into the
+ files silcd/idlist.[ch].
+
+Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * DIE command was renamed to SHUTDOWN. Updated the both code
+ and protocol specs.
+
+ * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
+ SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
+
+ * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
+ side.
+
+ * Added function silc_server_create_connection function to create
+ connection to remote router. My server implementation actually
+ does not allow router to connect to normal server (it expects
+ that normal server always initiates the connection to the router)
+ so the CONNECT command is only good for connecting to another
+ router.
+
+Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
+ or some other client was kicked from the channel.
+
+ Implemented the handling of the notify type to both client
+ and server.
+
+ Implemented silc_server_send_notify_kicked to send the KICKED
+ notify. It is used to send it to the server's primary router.
+
+ * Implemented the KICK command into server and client.
+
+ * Added `query' argument to the silc_idlist_get_client function
+ to indicate whether to query the client from server or not if
+ it was not found.
+
+ * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
+ to indicate that the client is not channel founder.
+
+ * Updated TODO.
+
+Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Removed the rng context from SilcPacketContext structure and
+ changed that the packet routine uses the Global RNG API.
+
+Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added support for quit message that client can "leave" on the
+ channel when it quits the SILC. It is ditributed inside the
+ SILC_NOTIFY_TYPE_SIGNOFF notify type.
+
+ Added silc_server_free_client_data that will take the
+ signoff message as argument.
+
+ * Changed SKE routines to use the silc_pkcs_sign/verify routines.
+
+Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Updated parts of the protocol specification to keep it up
+ to date.
+
+Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
+ payloads in one packet.
+
+ * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
+ NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
+ use now the new List flag.
+
+ * Also deprecated the following packet types: REPLACE_ID,
+ NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
+
+ * Added list support for Notify packet in server.
+
+ * Added silc_server_send_notify_channel_change to send the
+ CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
+ the silc_server_send_replace_id.
+
+ * Added silc_server_send_notify_nick_change to send the
+ NICK_CHANGE notify type. Deprecates the function
+ silc_server_send_replace_id.
+
+ * Added silc_server_send_notify_join to send the JOIN notify type.
+ Deprecates the function silc_server_send_new_channel_user.
+
+ * Added silc_server_send_notify_leave to send LEAVE notify type.
+ Deprecates the function silc_server_send_remove_channel_user.
+
+ * Added silc_server_send_notify_cmode and
+ silc_server_send_notify_cumode to send CMODE and CUMODE notify
+ types. Deprecates the silc_server_send_set_mode function.
+
+ * Added SERVER_SIGNOFF notify type to indicate that server has
+ quit. This means that all clients on the channel from that
+ server will drop. This can be also used when netsplit happens.
+
+ Deprecated REMOVE_ID packet type since it is not needed anymore
+ even from server.
+
+ Added silc_server_send_notify_server_signoff to send the
+ SERVER_SIGNOFF notify type. Deprecates the function
+ silc_server_send_remove_id.
+
+ Added also silc_server_send_notify_signoff to send the
+ SIGNOFF notify type.
+
+ * Employed the PKCS #1. It is the mandatory way to do RSA in the
+ SILC protocol from this day on. Changed the protocol
+ specification as well.
+
+ * Added silc_server_send_notify_topic_set to send TOPIC_SET
+ notify type. It is used between routers to notify about
+ topic changes on a channel.
+
+ * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
+ ID data.
+
+ * Partly updated the protocol specification to comply with the
+ changes now made. It is still though a bit outdated.
+
+ * The JOIN notify type now takes one extra argument <Channel ID>.
+ The packet used to be destined to the channel but now the
+ JOIN type may be sent as list thus it is impossible to
+ destine it to any specific channel. By adding this argument
+ it is again possible.
+
+Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added CREDITS file. The CHANGES and CREDITS file will appear
+ in the distribution as well.
+
+Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
+ types in the server's silcd/packet_receive.c.
+
+ * Implemented CMODE and CUMODE to work in router environment.
+
+ * Fixed minor encoding and decoding buglet from the
+ lib/silccore/silcmode.c.
+
+ * Fixed buffer overflow from lib/silcclient/command.c in USERS
+ command parsing.
+
+Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
+
+ * Changed all SilcConfigServer* and silc_config_server* to
+ SilcServerConfig* and silc_server_config*, respectively.
+ Patch by Bostik.
+
+Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Associated the ID (client or server ID) to the Authentication
+ Payload to avoid any possibility of forging. Updated the
+ protocol specification and the code accordingly.
+
+Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * The RSA key length is now save to the RsaKey context in the
+ key generation process in lib/silccrypt/rsa.c. The key length
+ is now used to figure out the maximum size of the block allowed
+ to be encrypted/signed.
+
+ * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
+ is equivalent to the silc_mp_mp2bin but does not allocate any
+ memory.
+
+ * Changed silc_mp_mp2bin API to take length argument. If it is
+ non-zero then the buffer is allocated that large. If zero, then
+ the size is approximated using silc_mp_sizeinbase, which however
+ is not relieable.
+
+ * Created Global RNG API which is global RNG that application can
+ initialize. After initializing, any routine anywhere in the
+ code (including library) can use RNG without allocating a new
+ RNG object. This was done to allow this sort of use of the
+ RNG in code that has no chance to allocate RNG object. All
+ applications currently allocate this and many routines in the
+ library use this. Affected file lib/silccrypt/silcrng.[ch].
+
+ * Removed the RNG kludge from lib/silcmath/primegen.c and changed
+ it to use the Global RNG API.
+
+ * Defined Authentication Payload into protocol specification that
+ is used during SILC session to authenticate entities. It is
+ used for example by client to authenticate itself to the server
+ to obtain server operator privileges.
+
+ Implemented this payload into the lib/silccore/silcauth.[ch].
+ Implemented also routines for public key based authentication
+ as the new protocol specification dictates.
+
+ Moved definitions of different authentication methods from
+ lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
+
+ * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
+ silc_pkcs_verify and silc_pkcs_sign_with_hash and
+ silc_pkcs_verify_with_hash functions into the file
+ lib/silccrypt/silcpkcs.[ch].
+
+Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * The client entry's userinfo pointer must be always valid.
+ Otherwise the [<unknown>] bug will surface beacuse the WHOIS
+ will fail since it requires the userinfo. Now, the userinfo
+ is allocated as "" if actual userinfo does not exist. Actually,
+ it must exist and it is totally Ok to drop client connections
+ that does not announce the userinfo. However, we will make
+ this workaround for now.
+
+ * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
+ to return the remote port by socket.
+
+Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
+ SILC_SERVER_PENDING_EXEC and added an new macro
+ SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
+ data or when error occurs while processing the pending command.
+
+ Added new argument `destructor' into silc_server_command_pending
+ and to the SilcServerCommandPending object. This destructor is
+ now called after calling the pending callback or if error occurs
+ immediately. If error occurs the actual pending callback won't
+ be called at all - only the destructor. The destructor may be
+ NULL if destructor is not needed.
+
+ All this applies for client library code as well. Similar
+ changes were made there as well for the pending commands.
+
+ In the client, the application must now allocate the
+ SilcClientCommandContext with the silc_client_command_alloc
+ function.
+
+ * Added reference counter to the SilcServerCommandContext. Added
+ function silc_server_command_alloc and silc_server_command_dup
+ functions.
+
+ Same type of functions added to the client library for the same
+ purpose as well.
+
+ * Removed the cmd_ident from IDListData away since it is now
+ global for all connections. It is the command identifier used
+ in command sending and with pending commands. The affected file
+ is silcd/idlist.h.
+
+ * Added reference counter to the SilcSocketConnection objecet to
+ indicate the usage count of the object. The object won't be
+ freed untill the reference counter hits zero. Currently only
+ server uses this, and client ignores it. The client must be
+ set to use this too later. The affected files are
+ lib/silccore/silcsockconn.[ch]. Added also the function
+ silc_socket_dup to increase the reference counter.
+
+ This was mainly added because it is possible that the socket
+ is removed underneath of pending command or other async
+ operation. Now it won't be free'd and proper DISCONNECTING
+ flags, etc. can be set to avoid sending data to connection that
+ is not valid anymore.
+
+ * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
+ the connection. After that it sets SILC_SET_DISCONNECTED.
+ It is, however, possible that the socket data is not still freed.
+ The silc_server_packet_process now checks that data is not
+ read or written to connection that is DISCONNECTED. The socket
+ get's freed when the reference counter hits zero.
+
+Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Changed the client operation API: channel_message operation's
+ `sender' is now the client entry of the sender, not the nickname
+ and the `channel' is the channel entry, not the channel name.
+
+ In the private_message operation the `sender' is now also the
+ client entry of the sender not the nickname.
+
+ Affected file is lib/silcclient/ops.h and all applications
+ using the client operations.
+
+Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Moved the calling of ops->connect() from connect_to_server_final
+ into receive_new_id functin since that is the point when the
+ client is actually allowed to send traffic to network. The
+ affected file is lib/silcclient/client.c.
+
+Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
+ NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
+ (if needs broadcasting) instead of broadcasting the packets one
+ by one which would make a burst in the network traffic.
+
+ * Added `broadcast' argument to the functions in silcd/server.[ch]
+ silc_server_create_new_channel[_with_id] to indicate whether
+ to send New Channel packet to primary router.
+
+Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added new function into the silcd/server.[ch] files:
+ silc_server_create_new_channel_with_id to create new channel with
+ already existing Channel ID.
+
+ * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
+ lib/silccore/silcpacket.h. This packet is used t send list of
+ Set Mode payloads inside one packet. Server uses this to set
+ the modes for the channels and clients on those channels, that it
+ announced to the router when it connected to it. The protocol
+ specification has been updated accordingly.
+
+ * The silc_server_new_channel did not handle the packet coming
+ from normal server as it normally does not send that. However,
+ when it announces its channels it does send it. Implemented
+ the support for that.
+
+ * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
+ into the file lib/silccore/id.h.
+
+Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Fixed memory leaks in the functions silc_idlist_del_client,
+ silc_idlist_del_channel and silc_idlist_del_server in the file
+ silcd/idlist.c. All of those leaked like a sieve.
+
+ * Fixed some small memory leaks in the client's function
+ silc_client_notify_by_server.
+
+ * Added functions into silcd/server.c: silc_server_announce_clients,
+ silc_server_announce_channels and silc_server_announce_server.
+ These functions are used by normal and router server to announce
+ to its primary router about clients, channels and servers (when
+ router) that we own. This is done after we've connected to the
+ router.
+
+ These functions effectively implements the following packet types:
+ SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
+ and SILC_PACKET_NEW_ID_LIST.
+
+ * Added new functions into the silcd/packet_receive.[ch]:
+ silc_server_new_id_list, silc_server_new_channel_list and
+ silc_server_new_channel_user_list to handle the incoming
+ NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
+
+ * Added support of changing Channel ID in the function
+ silc_server_replace_id. If the server that announces a channel
+ to the router already exists in the router (with same name but
+ with different Channel ID), router is responsible to send
+ Replace ID packet to the server and force the server to change
+ the Channel ID to the one router has.
+
+ * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
+ client that the Channel ID has been changed by the router. The
+ normal server sends this to the client. Client must start using
+ the new Channel ID as the channel's ID.
+
+ Implemented handling of this new type into lib/silcclient/client.c
+ into the function silc_client_notify_by_server.
+
+ * Added new function silc_idlist_replace_channel_id into the files
+ silcd/idlist.[ch] to replace the Channel ID.
+
+Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Call silc_server_command_identify_check always when processing
+ the IDENTIFY command in silcd/command.c
+
+Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added new packet type SILC_PACKET_HEARTBEAT that is used to
+ send keepalive packets. The packet can be sent by clients,
+ servers and routers.
+
+ Added function silc_socket_set_heartbeat into the file
+ lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
+ If not set, the heartbeat is not performed. The actual
+ heartbeat is implemented in the low level socket connection
+ library. However, application is responsible of actually
+ sending the packet.
+
+ Added silc_server_send_heartbeat to send the actual heartbeat
+ packet into silcd/packet_send.[ch]. Server now performs
+ keepalive with all connections.
+
+ * Added silc_task_get_first function into lib/silcutil/silctask.c
+ to return the timeout task with shortest timeout. There was a bug
+ in task unregistration that caused problems. TODO has been
+ updated to include that task system must be rewritten.
+
+ * The client library will now resolve the client information when
+ receiving JOIN notify from server for client that we know but
+ have incomplete information.
+
+ * Rewrote parts of silc_server_remove_from_channels and
+ silc_server_remove_from_one_channel as they did not remove the
+ channel in some circumstances even though they should've.
+
+ * Encryption problem encountered in server:
+
+ The LEAVE command used to send the Channel Key packet to the
+ router immediately after generating it. However, the code
+ had earlier sent Remove Channel user packet but not immediately,
+ ie. it was put to queue. The order of packets in the router
+ was that Channel Key packet was first and Remove Channel User
+ packet was second, even though they were encrypted in the
+ reverse order. For this reason, MAC check failed. Now, this
+ is fixed by not sending the Channel Key packet immediately but
+ putting it to queue. However, this is more fundamental problem:
+ packets that are in queue should actually not be encrypted
+ because packets that are sent immediately gets encrypted
+ actually with wrong IV (and thus MAC check fails). So, packets
+ that are in queue should be encrypted when they are sent to
+ the wire and not when they put to the queue.
+
+ However, the problem is that the current system has not been
+ designed to work that way. Instead, the packet is encrypted
+ as soon as possible and left to the queue. The queue is then
+ just purged into wire. There won't be any fixes for this
+ any time soon. So, the current semantic for packet sending
+ is as follows:
+
+ o If you send packet to remote host and do not force the send
+ (the packet will be in queue) then all subsequent packets to the
+ same remote host must also be put to the queue. Only after the
+ queue has been purged is it safe again to force the packet
+ send immediately.
+
+ o If you send all packets immediately then it safe to send
+ any of subsequent packets through the queue, however, after
+ the first packet is put to queue then any subsequent packets
+ must also be put to the queue.
+
+ Follow these rules and everything works fine.
+
+Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added new function silc_server_remove_clients_by_server to
+ remove all client entries from ID list when the server connection
+ is lost. In this case it is also important to invalidate all
+ client entires as they hold the invalid server entry. This
+ fixes fatal bug when server has lost connection and will reconnect
+ again.
+
+Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Made some sanity checks to silc_server_daemonise like to check
+ whether the requested user and group actually exists.
+
+ * Added sanity check to SKE's silc_ske_responder_finish to check
+ that the public and private key actually is valid.
+
+ * Invalidate the client's nickname when receiving Replace ID
+ packet and the Client ID is being replaced. This means that the
+ server will query the nickname if someone needs it (client)
+ a bit later.
+
+ * Sort the ID Cache in client library when the ID Cache data
+ has changed (needs sorting).
+
+ * Do not allow for SILC client to create several connections to
+ several servers. The client does not support windows right now
+ and generating multiple connections causes weird behaviour.
+
+ Irssi-silc client does support windows and can handle several
+ connections without problems, see: www.irssi.org and SILC plugin.
+
+ * Fixed some places where client was added to the IDList. The
+ rule of thumb is following (in order to get everything right):
+ If the client is directly connected local client then the
+ `connection' argument must be set and `router' argument must be
+ NULL to silc_idlist_add_client function. If the client is not
+ directly connected client then the `router' argument must
+ bet set and the `connection' argument must be NULL to the
+ silc_idlist_add_client function.
+
+ * The funtion silc_server_packet_send_local_channel actually did
+ not check whether the client was locally connected or not. It
+ does that now. Fixed a bug related to LEAVE command.
+
+ * Fixed Remove Channel User payload parsing bug in server's
+ silcd/packet_receive.c. Fixed a bug related to LEAVE command.
+
+ * The server's silc_server_save_channel_key now checks also the
+ global ID list for the channel as it might not be in the local
+ list. Fixed a bug related to LEAVE command.
+
+ * Is this the end of the [<unknown>] buglet that has been lurking
+ around for a long time? A little for loop fix in server's
+ silc_server_command_whois_parse that is used by both IDENTIFY
+ and WHOIS command. At least, this was a clear bug and a cause
+ of one type of [<unknown>] buglet.
+
+ * WHOIS and IDENTIFY commands call the function
+ silc_server_command_[whois/identify]_check function even if
+ we are not router server.
+
+Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added --with-gmp configuration option. If set the GMP
+ is always compiled in the SILC source tree. If not set then
+ it is checked whether the system has the GMP3 installed. If
+ it has then the GMP won't be compiled (the system's headers
+ and library is used), if it doesn't have it then the GMP is
+ compiled in the SILC source tree.
+
+Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Changed RSA private exponent generation to what PKCS #1
+ suggests. We try to find the smallest possible d by doing
+ modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
+ not security fix but optimization.
+
+Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added new config entry [Identity] to fork the server and run
+ it as specific user and group. A patch from Bostik.
+
+ * Imported Dotconf configuration library into lib/dotconf.
+ This will be used to create the SILC configuration files later.
+ It will appear in the distsribution after this commit.
+
+Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * A big code auditing weekend happening. Auditing code for
+ obvious mistakes, bugs and errors. Also, removing any code
+ that is obsolete.
+
+ Removed files for being obsolete:
+
+ o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
+ inline in the file lib/silcutil/silcbuffer.h)
+
+ o lib/silcutil/silcbufutil.c (the header has inline versions)
+
+ Changed code to fix possible error conditions:
+
+ o The buffer formatting routines now check that the destination
+ buffer really has enough space to add the data. This applies for
+ both buffer formatting and unformatting
+ (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
+ unformatting was changed to accomodate following rules:
+ XXX_*STRING_ALLOC will allocate space for the data into the pointer
+ sent to the function while XXX_*STRING will not allocate or copy
+ the data into the buffer. Instead it sets the pointer from the
+ buffer into the pointer sent as argument (XXX_*STRING used to
+ require that the pointer must be allocated already). This change
+ makes this whole thing a bit more consistent and more optimized
+ (note that the data returned in the unformatting with XXX_*STRING
+ must not be freed now). The routines return now -1 on error.
+
+ o Tried to find all code that use buffer_format and buffer_unformat
+ and added return value checking to prevent formatting and
+ especially unformatting errors and possible subsequent fatal
+ errors.
+
+ o Changed ske->x and ske->KEY to mallocated pointers in
+ lib/silcske/silcske.h. Fixed possible data and memory leak.
+
+ o Added return value checking to all *_parse* functions. Fixed
+ many memory leaks as well.
+
+ o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
+ so that buffer overflows would not happen. All code now also
+ checks the return value as it can fail.
+
+Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added reconnection support to server if the normal server looses
+ its connection to the router (for example if router is rebooted).
+ The server performs normal reconnection strategy implemented
+ to the server. Affected file silcd/server.c.
+
+Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added new packet type SILC_PACKET_SET_MODE that is used to
+ distribute the information about changed modes (for clients,
+ channels and clients channel modes) to all routers in the
+ network. Updated the protocol specification accordingly.
+
+ Added functions into silcd/packet_send.c and
+ silcd/packet_receive.c: silc_server_send_set_mode,
+ silc_server_set_mode.
+
+ Added new files silcmode.[ch] into lib/silccore that implements
+ the encoding and decoding of Set Mode Payload. Added new type
+ SilcSetModePayload. Moved the definitions of different modes
+ from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
+
+Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Oops, a little mistake in server's connection authentication
+ protocol. The protocol is not ended with FAILURE but with
+ SUCCESS if the authentication is Ok. :) Affected file is
+ silcd/protocol.c.
+
+ * Implemented NICK_CHANGE notify handling in server in the file
+ silcd/packet_receive.c The NICK_CHANGE notify is distributed to
+ the local clients on the channel. After the changing nickname
+ in router environment snhould work and the [<unknown>] nickname
+ should appear no more.
+
+ The silc_server_replace_id function that receives the Replace ID
+ payload now sends the NICK_CHANGE notify type also in the file
+ silcd/packet_receive.c
+
+ * Changed WHOIS and IDENTIFY command to support the maximum amount
+ of arguments defined in protocol specs (3328 arguments). This
+ fixed a bug that caused problems when there were more than three
+ users on a channel.
+
+Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Added extra parameter, command identifier, to the
+ silc_client_send_command so that explicit command identifier
+ can be defined.
+
+ Changed that ID list routines uses specific command identifier
+ when sending WHOIS/IDENTIFY requests to the server so that they
+ can be identified when the reply comes back.
+
+ Affected files lib/silcclient/command.[ch],
+ lib/silcclient/client.c and lib/silcclient/idlist.[ch].
+
+ * Added `sender' argument to silc_server_packet_send_to_channel
+ to indicaet the sender who originally sent the packet to us
+ that we are now re-sending. Ignored if NULL. Affected file
+ silcd/packet_send.[ch].
+
+ * Added some server statistics support in silcd/server_internal.h
+ SilcServerStatistics structure and around the server code. Also
+ send some nice statistics information when client is connecting
+ to the client.
+
+Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Fixed channel ID decoding in server's JOIN command reply in
+ silcd/command_reply.c
+
+ * Fixed braodcasting of replace ID payload to not to send it if
+ we are standalone server in silcd/packet_receive.c.
+
+ * Fixed all channel message sending routines to not to send
+ packets to clients that has router set, since they are routed
+ separately in the same function earlier. Affects file
+ silcd/packet_send.c and all channel packet sending functions.
+
+ * In USERS reply, res_argv[i] are not allocated, the table
+ is allocated. Thus changed that free the table, not its
+ internals.
+
+ * In server's whois_check and identify_check if the client is
+ locally connected do not send any WHOIS commands - they are not
+ needed.
+
+Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Fixed some minor bugs in client when sending WHOIS command. The
+ arguments was in wrong order.
+
+ * Removed statis function add_to_channel from server in
+ silcd/command.c that was previously used with the joining but
+ is obsolete now.
+
+ * Tested USERS command in router environment successfully with two
+ routers, two servers and two clients.
+
+Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Reorganized the USERS command and command reply in client library
+ in lib/silcclient/command.c and lib/silcclient/command_reply.c.
+ When the command is given by user we register a pending command
+ callback that will reprocess the command after the reply has been
+ received from the server. When reprocessing the packet we then
+ display the information. Thus, the USERS information is displayed
+ now in the command callback instead of in the command reply
+ callback. The processing of the command is same as previously
+ when server has sent the command reply in the JOINing process.
+
+ * Added to USERS command in silcd/command_reply.c to join the client,
+ we didn't use to know about, to the channel after we've created
+ a client entry for it. Also, for clienet we did know already still
+ check whether it is on the channel or not and add it if not.
+
+ * Removed silc_server_command_join_notify as the function and its
+ use was obsolete.
+
+Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
+
+ * Changed the client's pending command handling to the same as the
+ server's pending command handling. It is also now possible to
+ execute command reply functions from other command reply
+ function as the function callbacks for commands and command
+ replies are one and same. The pending commands are not static
+ list anymore, it is mallocated SilcDList in lib/silcclient/client.h
+ in client connection context. Thus, pending commands are server
+ connection specific as it is convenient.
+
+ Changed the function silc_client_command_pending and
+ silc_client_command_pending_del and added new function
+ silc_client_command_pending_check. Removed the
+ SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
+ macros.
+
+ * Added cmd_ident, current command identifier, to the client
+ connection context in lib/silcclient/client.h to keep track on
+ command identifiers used in command sending. Client's command reply
+ function handling now supports the mandatory command identifiers.
+
+ * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
+ funtions in client to fully support pending command callbacks.

+ * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
+ as one of the arguments to the application in the command reply
+ client operation.
+
+ * NOTE: The FORWARDED flag is depracated. It used to be depracated
+ before first releasing SILC but came back. Now it is removed again
+ and should come back nomore. The FORWARDED flag was used only
+ by the JOINing procedure by forwarding the command packet to router.
+ Now, the JOINing procedure has been changed to more generic (due
+ to various router environment issues) and FORWARDED is not needed
+ anymore for anything. The protocol specification is yet to be
+ updated.
+
+ Now, removed silc_server_packet_forward from server and the flag
+ SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
