+
+If a key is acquired, then all AFS operations, including mounts and automounts,
+made by a possessor of that key will be secured with that key.
+
+If a file is opened with a particular key and then the file descriptor is
+passed to a process that doesn't have that key (perhaps over an AF_UNIX

+			    RxRPC NETWORK PROTOCOL
+			    ======================
+
+The RxRPC protocol driver provides a reliable two-phase transport on top of UDP
+that can be used to perform RxRPC remote operations.  This is done over sockets
+of AF_RXRPC family, using sendmsg() and recvmsg() with control data to send and
+receive data, aborts and errors.
+

+
+
+========
+OVERVIEW
+========
+
+RxRPC is a two-layer protocol.  There is a session layer which provides
+reliable virtual connections using UDP over IPv4 (or IPv6) as the transport
+layer, but implements a real network protocol; and there's the presentation
+layer which renders structured data to binary blobs and back again using XDR
+(as does SunRPC):
+
+		+-------------+
+		| Application |
+		+-------------+
+		|     XDR     |		Presentation
+		+-------------+
+		|    RxRPC    |		Session
+		+-------------+
+		|     UDP     |		Transport
+		+-------------+
+
+
+AF_RXRPC provides:
+
+ (1) Part of an RxRPC facility for both kernel and userspace applications by
+     making the session part of it a Linux network protocol (AF_RXRPC).
+
+ (2) A two-phase protocol.  The client transmits a blob (the request) and then
+     receives a blob (the reply), and the server receives the request and then
+     transmits the reply.
+
+ (3) Retention of the reusable bits of the transport system set up for one call
+     to speed up subsequent calls.
+
+ (4) A secure protocol, using the Linux kernel's key retention facility to
+     manage security on the client end.  The server end must of necessity be
+     more active in security negotiations.
+
+AF_RXRPC does not provide XDR marshalling/presentation facilities.  That is
+left to the application.  AF_RXRPC only deals in blobs.  Even the operation ID
+is just the first four bytes of the request blob, and as such is beyond the
+kernel's interest.
+
+
+Sockets of AF_RXRPC family are:
+
+ (1) created as type SOCK_DGRAM;
+
+ (2) provided with a protocol of the type of underlying transport they're going
+     to use - currently only PF_INET is supported.
+
+
+The Andrew File System (AFS) is an example of an application that uses this and
+that has both kernel (filesystem) and userspace (utility) components.
+
+
+======================
+RXRPC PROTOCOL SUMMARY
+======================
+
+An overview of the RxRPC protocol:
+
+ (*) RxRPC sits on top of another networking protocol (UDP is the only option
+     currently), and uses this to provide network transport.  UDP ports, for
+     example, provide transport endpoints.
+
+ (*) RxRPC supports multiple virtual "connections" from any given transport
+     endpoint, thus allowing the endpoints to be shared, even to the same
+     remote endpoint.
+
+ (*) Each connection goes to a particular "service".  A connection may not go
+     to multiple services.  A service may be considered the RxRPC equivalent of
+     a port number.  AF_RXRPC permits multiple services to share an endpoint.
+
+ (*) Client-originating packets are marked, thus a transport endpoint can be
+     shared between client and server connections (connections have a
+     direction).
+
+ (*) Up to a billion connections may be supported concurrently between one
+     local transport endpoint and one service on one remote endpoint.  An RxRPC
+     connection is described by seven numbers:
+
+	Local address	}
+	Local port	} Transport (UDP) address
+	Remote address	}
+	Remote port	}
+	Direction
+	Connection ID
+	Service ID
+
+ (*) Each RxRPC operation is a "call".  A connection may make up to four
+     billion calls, but only up to four calls may be in progress on a
+     connection at any one time.
+
+ (*) Calls are two-phase and asymmetric: the client sends its request data,
+     which the service receives; then the service transmits the reply data
+     which the client receives.
+
+ (*) The data blobs are of indefinite size, the end of a phase is marked with a
+     flag in the packet.  The number of packets of data making up one blob may
+     not exceed 4 billion, however, as this would cause the sequence number to
+     wrap.
+
+ (*) The first four bytes of the request data are the service operation ID.
+
+ (*) Security is negotiated on a per-connection basis.  The connection is
+     initiated by the first data packet on it arriving.  If security is
+     requested, the server then issues a "challenge" and then the client
+     replies with a "response".  If the response is successful, the security is
+     set for the lifetime of that connection, and all subsequent calls made
+     upon it use that same security.  In the event that the server lets a
+     connection lapse before the client, the security will be renegotiated if
+     the client uses the connection again.
+
+ (*) Calls use ACK packets to handle reliability.  Data packets are also
+     explicitly sequenced per call.
+
+ (*) There are two types of positive acknowledgement: hard-ACKs and soft-ACKs.
+     A hard-ACK indicates to the far side that all the data received to a point
+     has been received and processed; a soft-ACK indicates that the data has
+     been received but may yet be discarded and re-requested.  The sender may
+     not discard any transmittable packets until they've been hard-ACK'd.
+
+ (*) Reception of a reply data packet implicitly hard-ACK's all the data
+     packets that make up the request.
+
+ (*) An call is complete when the request has been sent, the reply has been
+     received and the final hard-ACK on the last packet of the reply has
+     reached the server.
+
+ (*) An call may be aborted by either end at any time up to its completion.
+
+
+=====================
+AF_RXRPC DRIVER MODEL
+=====================
+
+About the AF_RXRPC driver:
+
+ (*) The AF_RXRPC protocol transparently uses internal sockets of the transport
+     protocol to represent transport endpoints.
+
+ (*) AF_RXRPC sockets map onto RxRPC connection bundles.  Actual RxRPC
+     connections are handled transparently.  One client socket may be used to
+     make multiple simultaneous calls to the same service.  One server socket
+     may handle calls from many clients.
+
+ (*) Additional parallel client connections will be initiated to support extra
+     concurrent calls, up to a tunable limit.
+
+ (*) Each connection is retained for a certain amount of time [tunable] after
+     the last call currently using it has completed in case a new call is made
+     that could reuse it.
+
+ (*) Each internal UDP socket is retained [tunable] for a certain amount of
+     time [tunable] after the last connection using it discarded, in case a new
+     connection is made that could use it.
+
+ (*) A client-side connection is only shared between calls if they have have
+     the same key struct describing their security (and assuming the calls
+     would otherwise share the connection).  Non-secured calls would also be
+     able to share connections with each other.
+
+ (*) A server-side connection is shared if the client says it is.
+
+ (*) ACK'ing is handled by the protocol driver automatically, including ping
+     replying.
+
+ (*) SO_KEEPALIVE automatically pings the other side to keep the connection
+     alive [TODO].
+
+ (*) If an ICMP error is received, all calls affected by that error will be
+     aborted with an appropriate network error passed through recvmsg().
+
+
+Interaction with the user of the RxRPC socket:
+
+ (*) A socket is made into a server socket by binding an address with a
+     non-zero service ID.
+
+ (*) In the client, sending a request is achieved with one or more sendmsgs,
+     followed by the reply being received with one or more recvmsgs.
+
+ (*) The first sendmsg for a request to be sent from a client contains a tag to
+     be used in all other sendmsgs or recvmsgs associated with that call.  The
+     tag is carried in the control data.
+
+ (*) connect() is used to supply a default destination address for a client
+     socket.  This may be overridden by supplying an alternate address to the
+     first sendmsg() of a call (struct msghdr::msg_name).
+
+ (*) If connect() is called on an unbound client, a random local port will
+     bound before the operation takes place.
+
+ (*) A server socket may also be used to make client calls.  To do this, the
+     first sendmsg() of the call must specify the target address.  The server's
+     transport endpoint is used to send the packets.
+
+ (*) Once the application has received the last message associated with a call,
+     the tag is guaranteed not to be seen again, and so it can be used to pin
+     client resources.  A new call can then be initiated with the same tag
+     without fear of interference.
+
+ (*) In the server, a request is received with one or more recvmsgs, then the
+     the reply is transmitted with one or more sendmsgs, and then the final ACK
+     is received with a last recvmsg.
+
+ (*) When sending data for a call, sendmsg is given MSG_MORE if there's more
+     data to come on that call.
+
+ (*) When receiving data for a call, recvmsg flags MSG_MORE if there's more
+     data to come for that call.
+
+ (*) When receiving data or messages for a call, MSG_EOR is flagged by recvmsg
+     to indicate the terminal message for that call.
+
+ (*) A call may be aborted by adding an abort control message to the control
+     data.  Issuing an abort terminates the kernel's use of that call's tag.
+     Any messages waiting in the receive queue for that call will be discarded.
+
+ (*) Aborts, busy notifications and challenge packets are delivered by recvmsg,
+     and control data messages will be set to indicate the context.  Receiving
+     an abort or a busy message terminates the kernel's use of that call's tag.
+
+ (*) The control data part of the msghdr struct is used for a number of things:
+
+     (*) The tag of the intended or affected call.
+
+     (*) Sending or receiving errors, aborts and busy notifications.
+
+     (*) Notifications of incoming calls.
+
+     (*) Sending debug requests and receiving debug replies [TODO].
+
+ (*) When the kernel has received and set up an incoming call, it sends a
+     message to server application to let it know there's a new call awaiting
+     its acceptance [recvmsg reports a special control message].  The server
+     application then uses sendmsg to assign a tag to the new call.  Once that
+     is done, the first part of the request data will be delivered by recvmsg.
+
+ (*) The server application has to provide the server socket with a keyring of
+     secret keys corresponding to the security types it permits.  When a secure
+     connection is being set up, the kernel looks up the appropriate secret key
+     in the keyring and then sends a challenge packet to the client and
+     receives a response packet.  The kernel then checks the authorisation of
+     the packet and either aborts the connection or sets up the security.
+
+ (*) The name of the key a client will use to secure its communications is
+     nominated by a socket option.
+
+
+Notes on recvmsg:
+
+ (*) If there's a sequence of data messages belonging to a particular call on
+     the receive queue, then recvmsg will keep working through them until:
+
+     (a) it meets the end of that call's received data,
+
+     (b) it meets a non-data message,
+
+     (c) it meets a message belonging to a different call, or
+
+     (d) it fills the user buffer.
+
+     If recvmsg is called in blocking mode, it will keep sleeping, awaiting the
+     reception of further data, until one of the above four conditions is met.
+
+ (2) MSG_PEEK operates similarly, but will return immediately if it has put any
+     data in the buffer rather than sleeping until it can fill the buffer.
+
+ (3) If a data message is only partially consumed in filling a user buffer,
+     then the remainder of that message will be left on the front of the queue
+     for the next taker.  MSG_TRUNC will never be flagged.
+
+ (4) If there is more data to be had on a call (it hasn't copied the last byte
+     of the last data message in that phase yet), then MSG_MORE will be
+     flagged.
+
+
+================
+CONTROL MESSAGES
+================
+
+AF_RXRPC makes use of control messages in sendmsg() and recvmsg() to multiplex
+calls, to invoke certain actions and to report certain conditions.  These are:
+
+	MESSAGE ID		SRT DATA	MEANING
+	=======================	=== ===========	===============================
+	RXRPC_USER_CALL_ID	sr- User ID	App's call specifier
+	RXRPC_ABORT		srt Abort code	Abort code to issue/received
+	RXRPC_ACK		-rt n/a		Final ACK received
+	RXRPC_NET_ERROR		-rt error num	Network error on call
+	RXRPC_BUSY		-rt n/a		Call rejected (server busy)
+	RXRPC_LOCAL_ERROR	-rt error num	Local error encountered
+	RXRPC_NEW_CALL		-r- n/a		New call received
+	RXRPC_ACCEPT		s-- n/a		Accept new call
+
+	(SRT = usable in Sendmsg / delivered by Recvmsg / Terminal message)
+
+ (*) RXRPC_USER_CALL_ID
+
+     This is used to indicate the application's call ID.  It's an unsigned long
+     that the app specifies in the client by attaching it to the first data
+     message or in the server by passing it in association with an RXRPC_ACCEPT
+     message.  recvmsg() passes it in conjunction with all messages except
+     those of the RXRPC_NEW_CALL message.
+
+ (*) RXRPC_ABORT
+
+     This is can be used by an application to abort a call by passing it to
+     sendmsg, or it can be delivered by recvmsg to indicate a remote abort was
+     received.  Either way, it must be associated with an RXRPC_USER_CALL_ID to
+     specify the call affected.  If an abort is being sent, then error EBADSLT
+     will be returned if there is no call with that user ID.
+
+ (*) RXRPC_ACK
+
+     This is delivered to a server application to indicate that the final ACK
+     of a call was received from the client.  It will be associated with an
+     RXRPC_USER_CALL_ID to indicate the call that's now complete.
+
+ (*) RXRPC_NET_ERROR
+
+     This is delivered to an application to indicate that an ICMP error message
+     was encountered in the process of trying to talk to the peer.  An
+     errno-class integer value will be included in the control message data
+     indicating the problem, and an RXRPC_USER_CALL_ID will indicate the call
+     affected.
+
+ (*) RXRPC_BUSY
+
+     This is delivered to a client application to indicate that a call was
+     rejected by the server due to the server being busy.  It will be
+     associated with an RXRPC_USER_CALL_ID to indicate the rejected call.
+
+ (*) RXRPC_LOCAL_ERROR
+
+     This is delivered to an application to indicate that a local error was
+     encountered and that a call has been aborted because of it.  An
+     errno-class integer value will be included in the control message data
+     indicating the problem, and an RXRPC_USER_CALL_ID will indicate the call
+     affected.
+
+ (*) RXRPC_NEW_CALL
+
+     This is delivered to indicate to a server application that a new call has
+     arrived and is awaiting acceptance.  No user ID is associated with this,
+     as a user ID must subsequently be assigned by doing an RXRPC_ACCEPT.
+
+ (*) RXRPC_ACCEPT
+
+     This is used by a server application to attempt to accept a call and
+     assign it a user ID.  It should be associated with an RXRPC_USER_CALL_ID
+     to indicate the user ID to be assigned.  If there is no call to be
+     accepted (it may have timed out, been aborted, etc.), then sendmsg will
+     return error ENODATA.  If the user ID is already in use by another call,
+     then error EBADSLT will be returned.
+
+
+==============
+SOCKET OPTIONS
+==============
+
+AF_RXRPC sockets support a few socket options at the SOL_RXRPC level:
+
+ (*) RXRPC_SECURITY_KEY
+
+     This is used to specify the description of the key to be used.  The key is
+     extracted from the calling process's keyrings with request_key() and
+     should be of "rxrpc" type.
+
+     The optval pointer points to the description string, and optlen indicates
+     how long the string is, without the NUL terminator.
+
+ (*) RXRPC_SECURITY_KEYRING
+
+     Similar to above but specifies a keyring of server secret keys to use (key
+     type "keyring").  See the "Security" section.
+
+ (*) RXRPC_EXCLUSIVE_CONNECTION
+
+     This is used to request that new connections should be used for each call
+     made subsequently on this socket.  optval should be NULL and optlen 0.
+
+ (*) RXRPC_MIN_SECURITY_LEVEL
+
+     This is used to specify the minimum security level required for calls on
+     this socket.  optval must point to an int containing one of the following
+     values:
+
+     (a) RXRPC_SECURITY_PLAIN
+
+	 Encrypted checksum only.
+
+     (b) RXRPC_SECURITY_AUTH
+
+	 Encrypted checksum plus packet padded and first eight bytes of packet
+	 encrypted - which includes the actual packet length.
+
+     (c) RXRPC_SECURITY_ENCRYPTED
+
+	 Encrypted checksum plus entire packet padded and encrypted, including
+	 actual packet length.
+
+
+========
+SECURITY
+========
+
+Currently, only the kerberos 4 equivalent protocol has been implemented
+(security index 2 - rxkad).  This requires the rxkad module to be loaded and,
+on the client, tickets of the appropriate type to be obtained from the AFS
+kaserver or the kerberos server and installed as "rxrpc" type keys.  This is
+normally done using the klog program.  An example simple klog program can be
+found at:
+
+	http://people.redhat.com/~dhowells/rxrpc/klog.c
+
+The payload provided to add_key() on the client should be of the following
+form:
+
+	struct rxrpc_key_sec2_v1 {
+		uint16_t	security_index;	/* 2 */
+		uint16_t	ticket_length;	/* length of ticket[] */
+		uint32_t	expiry;		/* time at which expires */
+		uint8_t		kvno;		/* key version number */
+		uint8_t		__pad[3];
+		uint8_t		session_key[8];	/* DES session key */
+		uint8_t		ticket[0];	/* the encrypted ticket */
+	};
+
+Where the ticket blob is just appended to the above structure.
+
+
+For the server, keys of type "rxrpc_s" must be made available to the server.
+They have a description of "<serviceID>:<securityIndex>" (eg: "52:2" for an
+rxkad key for the AFS VL service).  When such a key is created, it should be
+given the server's secret key as the instantiation data (see the example
+below).
+
+	add_key("rxrpc_s", "52:2", secret_key, 8, keyring);
+
+A keyring is passed to the server socket by naming it in a sockopt.  The server
+socket then looks the server secret keys up in this keyring when secure
+incoming connections are made.  This can be seen in an example program that can
+be found at:
+
+	http://people.redhat.com/~dhowells/rxrpc/listen.c
+
+
+====================
+EXAMPLE CLIENT USAGE
+====================
+
+A client would issue an operation by:
+
+ (1) An RxRPC socket is set up by:
+
+	client = socket(AF_RXRPC, SOCK_DGRAM, PF_INET);
+
+     Where the third parameter indicates the protocol family of the transport
+     socket used - usually IPv4 but it can also be IPv6 [TODO].
+
+ (2) A local address can optionally be bound:
+
+	struct sockaddr_rxrpc srx = {
+		.srx_family	= AF_RXRPC,
+		.srx_service	= 0,  /* we're a client */
+		.transport_type	= SOCK_DGRAM,	/* type of transport socket */
+		.transport.sin_family	= AF_INET,
+		.transport.sin_port	= htons(7000), /* AFS callback */
+		.transport.sin_address	= 0,  /* all local interfaces */
+	};
+	bind(client, &srx, sizeof(srx));
+
+     This specifies the local UDP port to be used.  If not given, a random
+     non-privileged port will be used.  A UDP port may be shared between
+     several unrelated RxRPC sockets.  Security is handled on a basis of
+     per-RxRPC virtual connection.
+
+ (3) The security is set:
+
+	const char *key = "AFS:cambridge.redhat.com";
+	setsockopt(client, SOL_RXRPC, RXRPC_SECURITY_KEY, key, strlen(key));
+
+     This issues a request_key() to get the key representing the security
+     context.  The minimum security level can be set:
+
+	unsigned int sec = RXRPC_SECURITY_ENCRYPTED;
+	setsockopt(client, SOL_RXRPC, RXRPC_MIN_SECURITY_LEVEL,
+		   &sec, sizeof(sec));
+
+ (4) The server to be contacted can then be specified (alternatively this can
+     be done through sendmsg):
+
+	struct sockaddr_rxrpc srx = {
+		.srx_family	= AF_RXRPC,
+		.srx_service	= VL_SERVICE_ID,
+		.transport_type	= SOCK_DGRAM,	/* type of transport socket */
+		.transport.sin_family	= AF_INET,
+		.transport.sin_port	= htons(7005), /* AFS volume manager */
+		.transport.sin_address	= ...,
+	};
+	connect(client, &srx, sizeof(srx));
+
+ (5) The request data should then be posted to the server socket using a series
+     of sendmsg() calls, each with the following control message attached:
+
+	RXRPC_USER_CALL_ID	- specifies the user ID for this call
+
+     MSG_MORE should be set in msghdr::msg_flags on all but the last part of
+     the request.  Multiple requests may be made simultaneously.
+
+     If a call is intended to go to a destination other then the default
+     specified through connect(), then msghdr::msg_name should be set on the
+     first request message of that call.
+
+ (6) The reply data will then be posted to the server socket for recvmsg() to
+     pick up.  MSG_MORE will be flagged by recvmsg() if there's more reply data
+     for a particular call to be read.  MSG_EOR will be set on the terminal
+     read for a call.
+
+     All data will be delivered with the following control message attached:
+
+	RXRPC_USER_CALL_ID	- specifies the user ID for this call
+
+     If an abort or error occurred, this will be returned in the control data
+     buffer instead, and MSG_EOR will be flagged to indicate the end of that
+     call.
+
+
+====================
+EXAMPLE SERVER USAGE
+====================
+
+A server would be set up to accept operations in the following manner:
+
+ (1) An RxRPC socket is created by:
+
+	server = socket(AF_RXRPC, SOCK_DGRAM, PF_INET);
+
+     Where the third parameter indicates the address type of the transport
+     socket used - usually IPv4.
+
+ (2) Security is set up if desired by giving the socket a keyring with server
+     secret keys in it:
+
+	keyring = add_key("keyring", "AFSkeys", NULL, 0,
+			  KEY_SPEC_PROCESS_KEYRING);
+
+	const char secret_key[8] = {
+		0xa7, 0x83, 0x8a, 0xcb, 0xc7, 0x83, 0xec, 0x94 };
+	add_key("rxrpc_s", "52:2", secret_key, 8, keyring);
+
+	setsockopt(server, SOL_RXRPC, RXRPC_SECURITY_KEYRING, "AFSkeys", 7);
+
+     The keyring can be manipulated after it has been given to the socket. This
+     permits the server to add more keys, replace keys, etc. whilst it is live.
+
+ (2) A local address must then be bound:
+
+	struct sockaddr_rxrpc srx = {
+		.srx_family	= AF_RXRPC,
+		.srx_service	= VL_SERVICE_ID, /* RxRPC service ID */
+		.transport_type	= SOCK_DGRAM,	/* type of transport socket */
+		.transport.sin_family	= AF_INET,
+		.transport.sin_port	= htons(7000), /* AFS callback */
+		.transport.sin_address	= 0,  /* all local interfaces */
+	};
+	bind(server, &srx, sizeof(srx));
+
+ (3) The server is then set to listen out for incoming calls:
+
+	listen(server, 100);
+
+ (4) The kernel notifies the server of pending incoming connections by sending
+     it a message for each.  This is received with recvmsg() on the server
+     socket.  It has no data, and has a single dataless control message
+     attached:
+
+	RXRPC_NEW_CALL
+
+     The address that can be passed back by recvmsg() at this point should be
+     ignored since the call for which the message was posted may have gone by
+     the time it is accepted - in which case the first call still on the queue
+     will be accepted.
+
+ (5) The server then accepts the new call by issuing a sendmsg() with two
+     pieces of control data and no actual data:
+
+	RXRPC_ACCEPT		- indicate connection acceptance
+	RXRPC_USER_CALL_ID	- specify user ID for this call
+
+ (6) The first request data packet will then be posted to the server socket for
+     recvmsg() to pick up.  At that point, the RxRPC address for the call can
+     be read from the address fields in the msghdr struct.
+
+     Subsequent request data will be posted to the server socket for recvmsg()
+     to collect as it arrives.  All but the last piece of the request data will
+     be delivered with MSG_MORE flagged.
+
+     All data will be delivered with the following control message attached:
+
+	RXRPC_USER_CALL_ID	- specifies the user ID for this call
+
+ (8) The reply data should then be posted to the server socket using a series
+     of sendmsg() calls, each with the following control messages attached:
+
+	RXRPC_USER_CALL_ID	- specifies the user ID for this call
+
+     MSG_MORE should be set in msghdr::msg_flags on all but the last message
+     for a particular call.
+
+ (9) The final ACK from the client will be posted for retrieval by recvmsg()
+     when it is received.  It will take the form of a dataless message with two
+     control messages attached:
+
+	RXRPC_USER_CALL_ID	- specifies the user ID for this call
+	RXRPC_ACK		- indicates final ACK (no data)
+
+     MSG_EOR will be flagged to indicate that this is the final message for
+     this call.
+
+(10) Up to the point the final packet of reply data is sent, the call can be
+     aborted by calling sendmsg() with a dataless message with the following
+     control messages attached:
+
+	RXRPC_USER_CALL_ID	- specifies the user ID for this call
+	RXRPC_ABORT		- indicates abort code (4 byte data)
+
+     Any packets waiting in the socket's receive queue will be discarded if
+     this is issued.
+
+Note that all the communications for a particular service take place through
+the one server socket, using control messages on sendmsg() and recvmsg() to
+determine the call affected.
+
+
+=========================
+AF_RXRPC KERNEL INTERFACE
+=========================
+
+The AF_RXRPC module also provides an interface for use by in-kernel utilities
+such as the AFS filesystem.  This permits such a utility to:
+
+ (1) Use different keys directly on individual client calls on one socket
+     rather than having to open a whole slew of sockets, one for each key it
+     might want to use.
+
+ (2) Avoid having RxRPC call request_key() at the point of issue of a call or
+     opening of a socket.  Instead the utility is responsible for requesting a
+     key at the appropriate point.  AFS, for instance, would do this during VFS
+     operations such as open() or unlink().  The key is then handed through
+     when the call is initiated.
+
+ (3) Request the use of something other than GFP_KERNEL to allocate memory.
+
+ (4) Avoid the overhead of using the recvmsg() call.  RxRPC messages can be
+     intercepted before they get put into the socket Rx queue and the socket
+     buffers manipulated directly.
+
+To use the RxRPC facility, a kernel utility must still open an AF_RXRPC socket,
+bind an addess as appropriate and listen if it's to be a server socket, but
+then it passes this to the kernel interface functions.
+
+The kernel interface functions are as follows:
+
+ (*) Begin a new client call.
+
+	struct rxrpc_call *
+	rxrpc_kernel_begin_call(struct socket *sock,
+				struct sockaddr_rxrpc *srx,
+				struct key *key,
+				unsigned long user_call_ID,
+				gfp_t gfp);
+
+     This allocates the infrastructure to make a new RxRPC call and assigns
+     call and connection numbers.  The call will be made on the UDP port that
+     the socket is bound to.  The call will go to the destination address of a
+     connected client socket unless an alternative is supplied (srx is
+     non-NULL).
+
+     If a key is supplied then this will be used to secure the call instead of
+     the key bound to the socket with the RXRPC_SECURITY_KEY sockopt.  Calls
+     secured in this way will still share connections if at all possible.
+
+     The user_call_ID is equivalent to that supplied to sendmsg() in the
+     control data buffer.  It is entirely feasible to use this to point to a
+     kernel data structure.
+
+     If this function is successful, an opaque reference to the RxRPC call is
+     returned.  The caller now holds a reference on this and it must be
+     properly ended.
+
+ (*) End a client call.
+
+	void rxrpc_kernel_end_call(struct rxrpc_call *call);
+
+     This is used to end a previously begun call.  The user_call_ID is expunged
+     from AF_RXRPC's knowledge and will not be seen again in association with
+     the specified call.
+
+ (*) Send data through a call.
+
+	int rxrpc_kernel_send_data(struct rxrpc_call *call, struct msghdr *msg,
+				   size_t len);
+
+     This is used to supply either the request part of a client call or the
+     reply part of a server call.  msg.msg_iovlen and msg.msg_iov specify the
+     data buffers to be used.  msg_iov may not be NULL and must point
+     exclusively to in-kernel virtual addresses.  msg.msg_flags may be given
+     MSG_MORE if there will be subsequent data sends for this call.
+
+     The msg must not specify a destination address, control data or any flags
+     other than MSG_MORE.  len is the total amount of data to transmit.
+
+ (*) Abort a call.
+
+	void rxrpc_kernel_abort_call(struct rxrpc_call *call, u32 abort_code);
+
+     This is used to abort a call if it's still in an abortable state.  The
+     abort code specified will be placed in the ABORT message sent.
+
+ (*) Intercept received RxRPC messages.
+
+	typedef void (*rxrpc_interceptor_t)(struct sock *sk,
+					    unsigned long user_call_ID,
+					    struct sk_buff *skb);
+
+	void
+	rxrpc_kernel_intercept_rx_messages(struct socket *sock,
+					   rxrpc_interceptor_t interceptor);
+
+     This installs an interceptor function on the specified AF_RXRPC socket.
+     All messages that would otherwise wind up in the socket's Rx queue are
+     then diverted to this function.  Note that care must be taken to process
+     the messages in the right order to maintain DATA message sequentiality.
+
+     The interceptor function itself is provided with the address of the socket
+     and handling the incoming message, the ID assigned by the kernel utility
+     to the call and the socket buffer containing the message.
+
+     The skb->mark field indicates the type of message:
+
+	MARK				MEANING
+	===============================	=======================================
+	RXRPC_SKB_MARK_DATA		Data message
+	RXRPC_SKB_MARK_FINAL_ACK	Final ACK received for an incoming call
+	RXRPC_SKB_MARK_BUSY		Client call rejected as server busy
+	RXRPC_SKB_MARK_REMOTE_ABORT	Call aborted by peer
+	RXRPC_SKB_MARK_NET_ERROR	Network error detected
+	RXRPC_SKB_MARK_LOCAL_ERROR	Local error encountered
+	RXRPC_SKB_MARK_NEW_CALL		New incoming call awaiting acceptance
+
+     The remote abort message can be probed with rxrpc_kernel_get_abort_code().
+     The two error messages can be probed with rxrpc_kernel_get_error_number().
+     A new call can be accepted with rxrpc_kernel_accept_call().
+
+     Data messages can have their contents extracted with the usual bunch of
+     socket buffer manipulation functions.  A data message can be determined to
+     be the last one in a sequence with rxrpc_kernel_is_data_last().  When a
+     data message has been used up, rxrpc_kernel_data_delivered() should be
+     called on it..
+
+     Non-data messages should be handled to rxrpc_kernel_free_skb() to dispose
+     of.  It is possible to get extra refs on all types of message for later
+     freeing, but this may pin the state of a call until the message is finally
+     freed.
+
+ (*) Accept an incoming call.
+
+	struct rxrpc_call *
+	rxrpc_kernel_accept_call(struct socket *sock,
+				 unsigned long user_call_ID);
+
+     This is used to accept an incoming call and to assign it a call ID.  This
+     function is similar to rxrpc_kernel_begin_call() and calls accepted must
+     be ended in the same way.
+
+     If this function is successful, an opaque reference to the RxRPC call is
+     returned.  The caller now holds a reference on this and it must be
+     properly ended.
+
+ (*) Reject an incoming call.
+
+	int rxrpc_kernel_reject_call(struct socket *sock);
+
+     This is used to reject the first incoming call on the socket's queue with
+     a BUSY message.  -ENODATA is returned if there were no incoming calls.
+     Other errors may be returned if the call had been aborted (-ECONNABORTED)
+     or had timed out (-ETIME).
+
+ (*) Record the delivery of a data message and free it.
+
+	void rxrpc_kernel_data_delivered(struct sk_buff *skb);
+
+     This is used to record a data message as having been delivered and to
+     update the ACK state for the call.  The socket buffer will be freed.
+
+ (*) Free a message.
+
+	void rxrpc_kernel_free_skb(struct sk_buff *skb);
+
+     This is used to free a non-DATA socket buffer intercepted from an AF_RXRPC
+     socket.
+
+ (*) Determine if a data message is the last one on a call.
+
+	bool rxrpc_kernel_is_data_last(struct sk_buff *skb);
+
+     This is used to determine if a socket buffer holds the last data message
+     to be received for a call (true will be returned if it does, false
+     if not).
+
+     The data message will be part of the reply on a client call and the
+     request on an incoming call.  In the latter case there will be more
+     messages, but in the former case there will not.
+
+ (*) Get the abort code from an abort message.
+
+	u32 rxrpc_kernel_get_abort_code(struct sk_buff *skb);
+
+     This is used to extract the abort code from a remote abort message.
+
+ (*) Get the error number from a local or network error message.
+
+	int rxrpc_kernel_get_error_number(struct sk_buff *skb);
+
+     This is used to extract the error number from a message indicating either
+     a local error occurred or a network error occurred.

-crypto-API support for z990 Message Security Assist (MSA) instructions
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-AUTHOR:	Thomas Spatzier (tspat@de.ibm.com)
-
-
-1. Introduction crypto-API
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-See Documentation/crypto/api-intro.txt for an introduction/description of the
-kernel crypto API.
-According to api-intro.txt support for z990 crypto instructions has been added
-in the algorithm api layer of the crypto API. Several files containing z990
-optimized implementations of crypto algorithms are placed in the
-arch/s390/crypto directory.
-
-
-2. Probing for availability of MSA
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-It should be possible to use Kernels with the z990 crypto implementations both
-on machines with MSA available and on those without MSA (pre z990 or z990
-without MSA). Therefore a simple probing mechanism has been implemented:
-In the init function of each crypto module the availability of MSA and of the
-respective crypto algorithm in particular will be tested. If the algorithm is
-available the module will load and register its algorithm with the crypto API.
-
-If the respective crypto algorithm is not available, the init function will
-return -ENOSYS. In that case a fallback to the standard software implementation
-of the crypto algorithm must be taken ( -> the standard crypto modules are
-also built when compiling the kernel).
-
-
-3. Ensuring z990 crypto module preference
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-If z990 crypto instructions are available the optimized modules should be
-preferred instead of standard modules.
-
-3.1. compiled-in modules
-~~~~~~~~~~~~~~~~~~~~~~~~
-For compiled-in modules it has to be ensured that the z990 modules are linked
-before the standard crypto modules. Then, on system startup the init functions
-of z990 crypto modules will be called first and query for availability of z990
-crypto instructions. If instruction is available, the z990 module will register
-its crypto algorithm implementation -> the load of the standard module will fail
-since the algorithm is already registered.
-If z990 crypto instruction is not available the load of the z990 module will
-fail -> the standard module will load and register its algorithm.
-
-3.2. dynamic modules
-~~~~~~~~~~~~~~~~~~~~
-A system administrator has to take care of giving preference to z990 crypto
-modules. If MSA is available appropriate lines have to be added to
-/etc/modprobe.conf.
-
-Example:	z990 crypto instruction for SHA1 algorithm is available
-
-		add the following line to /etc/modprobe.conf (assuming the
-		z990 crypto modules for SHA1 is called sha1_z990):
-
-		alias sha1 sha1_z990
-
-		-> when the sha1 algorithm is requested through the crypto API
-		(which has a module autoloader) the z990 module will be loaded.
-
-TBD:	a userspace module probing mechanism
-	something like 'probe sha1 sha1_z990 sha1' in modprobe.conf
-	-> try module sha1_z990, if it fails to load standard module sha1
-	the 'probe' statement is currently not supported in modprobe.conf
-
-
-4. Currently implemented z990 crypto algorithms
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-The following crypto algorithms with z990 MSA support are currently implemented.
-The name of each algorithm under which it is registered in crypto API and the
-name of the respective module is given in square brackets.
-
-- SHA1 Digest Algorithm [sha1 -> sha1_z990]
-- DES Encrypt/Decrypt Algorithm (64bit key) [des -> des_z990]
-- Triple DES Encrypt/Decrypt Algorithm (128bit key) [des3_ede128 -> des_z990]
-- Triple DES Encrypt/Decrypt Algorithm (192bit key) [des3_ede -> des_z990]
-
-In order to load, for example, the sha1_z990 module when the sha1 algorithm is
-requested (see 3.2.) add 'alias sha1 sha1_z990' to /etc/modprobe.conf.

+s390 SCSI dump tool (zfcpdump)
+
+System z machines (z900 or higher) provide hardware support for creating system
+dumps on SCSI disks. The dump process is initiated by booting a dump tool, which
+has to create a dump of the current (probably crashed) Linux image. In order to
+not overwrite memory of the crashed Linux with data of the dump tool, the
+hardware saves some memory plus the register sets of the boot cpu before the
+dump tool is loaded. There exists an SCLP hardware interface to obtain the saved
+memory afterwards. Currently 32 MB are saved.
+
+This zfcpdump implementation consists of a Linux dump kernel together with
+a userspace dump tool, which are loaded together into the saved memory region
+below 32 MB. zfcpdump is installed on a SCSI disk using zipl (as contained in
+the s390-tools package) to make the device bootable. The operator of a Linux
+system can then trigger a SCSI dump by booting the SCSI disk, where zfcpdump
+resides on.
+
+The kernel part of zfcpdump is implemented as a debugfs file under "zcore/mem",
+which exports memory and registers of the crashed Linux in an s390
+standalone dump format. It can be used in the same way as e.g. /dev/mem. The
+dump format defines a 4K header followed by plain uncompressed memory. The
+register sets are stored in the prefix pages of the respective cpus. To build a
+dump enabled kernel with the zcore driver, the kernel config option
+CONFIG_ZFCPDUMP has to be set. When reading from "zcore/mem", the part of
+memory, which has been saved by hardware is read by the driver via the SCLP
+hardware interface. The second part is just copied from the non overwritten real
+memory.
+
+The userspace application of zfcpdump can reside e.g. in an intitramfs or an
+initrd. It reads from zcore/mem and writes the system dump to a file on a
+SCSI disk.
+
+To build a zfcpdump kernel use the following settings in your kernel
+configuration:
+ * CONFIG_ZFCPDUMP=y
+ * Enable ZFCP driver
+ * Enable SCSI driver
+ * Enable ext2 and ext3 filesystems
+ * Disable as many features as possible to keep the kernel small.
+   E.g. network support is not needed at all.
+
+To use the zfcpdump userspace application in an initramfs you have to do the
+following:
+
+ * Copy the zfcpdump executable somewhere into your Linux tree.
+   E.g. to "arch/s390/boot/zfcpdump. If you do not want to include
+   shared libraries, compile the tool with the "-static" gcc option.
+ * If you want to include e2fsck, add it to your source tree, too. The zfcpdump
+   application attempts to start /sbin/e2fsck from the ramdisk.
+ * Use an initramfs config file like the following:
+
+   dir /dev 755 0 0
+   nod /dev/console 644 0 0 c 5 1
+   nod /dev/null 644 0 0 c 1 3
+   nod /dev/sda1 644 0 0 b 8 1
+   nod /dev/sda2 644 0 0 b 8 2
+   nod /dev/sda3 644 0 0 b 8 3
+   nod /dev/sda4 644 0 0 b 8 4
+   nod /dev/sda5 644 0 0 b 8 5
+   nod /dev/sda6 644 0 0 b 8 6
+   nod /dev/sda7 644 0 0 b 8 7
+   nod /dev/sda8 644 0 0 b 8 8
+   nod /dev/sda9 644 0 0 b 8 9
+   nod /dev/sda10 644 0 0 b 8 10
+   nod /dev/sda11 644 0 0 b 8 11
+   nod /dev/sda12 644 0 0 b 8 12
+   nod /dev/sda13 644 0 0 b 8 13
+   nod /dev/sda14 644 0 0 b 8 14
+   nod /dev/sda15 644 0 0 b 8 15
+   file /init arch/s390/boot/zfcpdump 755 0 0
+   file /sbin/e2fsck arch/s390/boot/e2fsck 755 0 0
+   dir /proc 755 0 0
+   dir /sys 755 0 0
+   dir /mnt 755 0 0
+   dir /sbin 755 0 0
+
+ * Issue "make image" to build the zfcpdump image with initramfs.
+
+In a Linux distribution the zfcpdump enabled kernel image must be copied to
+/usr/share/zfcpdump/zfcpdump.image, where the s390 zipl tool is looking for the
+dump kernel when preparing a SCSI dump disk.
+
+If you use a ramdisk copy it to "/usr/share/zfcpdump/zfcpdump.rd".
+
+For more information on how to use zfcpdump refer to the s390 'Using the Dump
+Tools book', which is available from
+http://www.ibm.com/developerworks/linux/linux390.
