+ 0 means the device will be autosuspended as soon as

+ will resume the device if it is already suspended.
+
+ The autosuspend delay for newly-created devices is set to

+KernelVersion: 2.6.21
+Contact: Alan Stern <stern@rowland.harvard.edu>
+Description:
+ Each USB device directory will contain a file named
+ power/level. This file holds a power-level setting for
+ the device, one of "on", "auto", or "suspend".
+
+ "on" means that the device is not allowed to autosuspend,
+ although normal suspends for system sleep will still
+ be honored. "auto" means the device will autosuspend
+ and autoresume in the usual manner, according to the
+ capabilities of its driver. "suspend" means the device
+ is forced into a suspended state and it will not autoresume
+ in response to I/O requests. However remote-wakeup requests
+ from the device may still be enabled (the remote-wakeup
+ setting is controlled separately by the power/wakeup
+ attribute).
+
+ During normal use, devices should be left in the "auto"
+ level. The other levels are meant for administrative uses.
+ If you want to suspend a device immediately but leave it
+ free to wake up in response to I/O requests, you should
+ write "0" to power/autosuspend.

+The filesystem should be enabled by turning on the kernel configuration
+options:
+
+ CONFIG_AF_RXRPC - The RxRPC protocol transport
+ CONFIG_RXKAD - The RxRPC Kerberos security handler
+ CONFIG_AFS - The AFS filesystem
+
+Additionally, the following can be turned on to aid debugging:
+
+ CONFIG_AF_RXRPC_DEBUG - Permit AF_RXRPC debugging to be enabled
+ CONFIG_AFS_DEBUG - Permit AFS debugging to be enabled
+
+They permit the debugging messages to be turned on dynamically by manipulating
+the masks in the following files:

+AFS has a concept of mountpoints. In AFS terms, these are specially formatted
+symbolic links (of the same form as the "device name" passed to mount). kAFS
+presents these to the user as directories that have a follow-link capability
+(ie: symbolic link semantics). If anyone attempts to access them, they will
+automatically cause the target volume to be mounted (if possible) on that site.
- (*) They cannot be listed. Running a program like "ls" on them will incur an
- EREMOTE error (Object is remote).
+Automatically mounted filesystems will be automatically unmounted approximately
+twenty minutes after they were last used. Alternatively they can be unmounted
+directly with the umount() system call.
- (*) Other objects can't be looked up inside of them. This also incurs an
- EREMOTE error.
+Manually unmounting an AFS volume will cause any idle submounts upon it to be
+culled first. If all are culled, then the requested volume will also be
+unmounted, otherwise error EBUSY will be returned.
- (*) They can be queried with the readlink() system call, which will return
- the name of the mountpoint to which they point. The "readlink" program
- will also work.

PROC FILESYSTEM
===============
-The rxrpc module creates a number of files in various places in the /proc
-filesystem:
-
- (*) Firstly, some information files are made available in a directory called
- "/proc/net/rxrpc/". These list the extant transport endpoint, peer,
- connection and call records.
-
- (*) Secondly, some control files are made available in a directory called
- "/proc/sys/rxrpc/". Currently, all these files can be used for is to
- turn on various levels of tracing.
-
The AFS modules creates a "/proc/fs/afs/" directory and populates it:
- (*) A "cells" file that lists cells currently known to the afs module.
+ (*) A "cells" file that lists cells currently known to the afs module and
+ their usage counts:
+
+ [root@andromeda ~]# cat /proc/fs/afs/cells

+This should be compiled by:
+

+If a file is opened with a particular key and then the file descriptor is

+Emulating Open Drain Signals
+----------------------------
+Sometimes shared signals need to use "open drain" signaling, where only the
+low signal level is actually driven. (That term applies to CMOS transistors;
+"open collector" is used for TTL.) A pullup resistor causes the high signal
+level. This is sometimes called a "wire-AND"; or more practically, from the
+negative logic (low=true) perspective this is a "wire-OR".
+
+One common example of an open drain signal is a shared active-low IRQ line.
+Also, bidirectional data bus signals sometimes use open drain signals.
+
+Some GPIO controllers directly support open drain outputs; many don't. When
+you need open drain signaling but your hardware doesn't directly support it,
+there's a common idiom you can use to emulate it with any GPIO pin that can
+be used as either an input or an output:
+
+ LOW: gpio_direction_output(gpio, 0) ... this drives the signal
+ and overrides the pullup.
+
+ HIGH: gpio_direction_input(gpio) ... this turns off the output,
+ so the pullup (or some other device) controls the signal.
+
+If you are "driving" the signal high but gpio_get_value(gpio) reports a low
+value (after the appropriate rise time passes), you know some other component
+is driving the shared signal low. That's not necessarily an error. As one
+common example, that's how I2C clocks are stretched: a slave that needs a
+slower clock delays the rising edge of SCK, and the I2C master adjusts its

+ 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

+
+ * 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.

* Raw text data format
-The '1t' type data consists of a stream of events, such as URB submission,
+Two formats are supported currently: the original, or '1t' format, and
+the '1u' format. The '1t' format is deprecated in kernel 2.6.21. The '1u'
+format adds a few fields, such as ISO frame descriptors, interval, etc.
+It produces slightly longer lines, but otherwise is a perfect superset
+of '1t' format.
+
+If it is desired to recognize one from the other in a program, look at the
+"address" word (see below), where '1u' format adds a bus number. If 2 colons
+are present, it's the '1t' format, otherwise '1u'.
+
+Any text format data consists of a stream of events, such as URB submission,
URB callback, submission error. Every event is a text line, which consists
of whitespace separated words. The number or position of words may depend
on the event type, but there is a set of words, common for all types.
Here is the list of words, from left to right:
+
- URB Tag. This is used to identify URBs is normally a kernel mode address
of the URB structure in hexadecimal.
+
- Timestamp in microseconds, a decimal number. The timestamp's resolution
depends on available clock, and so it can be much worse than a microsecond
(if the implementation uses jiffies, for example).
+
- Event Type. This type refers to the format of the event, not URB type.
Available types are: S - submission, C - callback, E - submission error.
-- "Pipe". The pipe concept is deprecated. This is a composite word, used to
- be derived from information in pipes. It consists of three fields, separated
- by colons: URB type and direction, Device address, Endpoint number.
+
+- "Address" word (formerly a "pipe"). It consists of four fields, separated by
+ colons: URB type and direction, Bus number, Device address, Endpoint number.
Type and direction are encoded with two bytes in the following manner:
Ci Co Control input and output
Zi Zo Isochronous input and output
Ii Io Interrupt input and output
Bi Bo Bulk input and output
- Device address and Endpoint number are 3-digit and 2-digit (respectively)
- decimal numbers, with leading zeroes.
-- URB Status. In most cases, this field contains a number, sometimes negative,
- which represents a "status" field of the URB. This field makes no sense for
- submissions, but is present anyway to help scripts with parsing. When an
- error occurs, the field contains the error code. In case of a submission of
- a Control packet, this field contains a Setup Tag instead of an error code.
- It is easy to tell whether the Setup Tag is present because it is never a
- number. Thus if scripts find a number in this field, they proceed to read
- Data Length. If they find something else, like a letter, they read the setup
- packet before reading the Data Length.
+ Bus number, Device address, and Endpoint are decimal numbers, but they may
+ have leading zeros, for the sake of human readers.
+
+- URB Status word. This is either a letter, or several numbers separated
+ by colons: URB status, interval, start frame, and error count. Unlike the
+ "address" word, all fields save the status are optional. Interval is printed
+ only for interrupt and isochronous URBs. Start frame is printed only for
+ isochronous URBs. Error count is printed only for isochronous callback
+ events.
+
+ The status field is a decimal number, sometimes negative, which represents
+ a "status" field of the URB. This field makes no sense for submissions, but
+ is present anyway to help scripts with parsing. When an error occurs, the
+ field contains the error code.
+
+ In case of a submission of a Control packet, this field contains a Setup Tag
+ instead of an group of numbers. It is easy to tell whether the Setup Tag is
+ present because it is never a number. Thus if scripts find a set of numbers
+ in this word, they proceed to read Data Length (except for isochronous URBs).
+ If they find something else, like a letter, they read the setup packet before
+ reading the Data Length or isochronous descriptors.
+
- Setup packet, if present, consists of 5 words: one of each for bmRequestType,
bRequest, wValue, wIndex, wLength, as specified by the USB Specification 2.0.
These words are safe to decode if Setup Tag was 's'. Otherwise, the setup
packet was present, but not captured, and the fields contain filler.
+
+- Number of isochronous frame descriptors and descriptors themselves.
+ If an Isochronous transfer event has a set of descriptors, a total number
+ of them in an URB is printed first, then a word per descriptor, up to a
+ total of 5. The word consists of 3 colon-separated decimal numbers for
+ status, offset, and length respectively. For submissions, initial length
+ is reported. For callbacks, actual length is reported.
+
- Data Length. For submissions, this is the requested length. For callbacks,
this is the actual length.
+
- Data tag. The usbmon may not always capture data, even if length is nonzero.
The data words are present only if this tag is '='.
+
- Data words follow, in big endian hexadecimal format. Notice that they are
not machine words, but really just a byte stream split into words to make
it easier to read. Thus, the last word may contain from one to four bytes.

+ivtv release notes
+==================
+
+This is a v4l2 device driver for the Conexant cx23415/6 MPEG encoder/decoder.
+The cx23415 can do both encoding and decoding, the cx23416 can only do MPEG
+encoding. Currently the only card featuring full decoding support is the
+Hauppauge PVR-350.
+
+NOTE: this driver requires the latest encoder firmware (version 2.06.039, size
+376836 bytes). Get the firmware from here:
+
+http://dl.ivtvdriver.org/ivtv/firmware/firmware.tar.gz
+
+NOTE: 'normal' TV applications do not work with this driver, you need
+an application that can handle MPEG input such as mplayer, xine, MythTV,
+etc.
+
+The primary goal of the IVTV project is to provide a "clean room" Linux
+Open Source driver implementation for video capture cards based on the
+iCompression iTVC15 or Conexant CX23415/CX23416 MPEG Codec.
+
+Features:
+ * Hardware mpeg2 capture of broadcast video (and sound) via the tuner or
+ S-Video/Composite and audio line-in.
+ * Hardware mpeg2 capture of FM radio where hardware support exists
+ * Supports NTSC, PAL, SECAM with stereo sound
+ * Supports SAP and bilingual transmissions.
+ * Supports raw VBI (closed captions and teletext).
+ * Supports sliced VBI (closed captions and teletext) and is able to insert
+ this into the captured MPEG stream.
+ * Supports raw YUV and PCM input.
+
+Additional features for the PVR-350 (CX23415 based):
+ * Provides hardware mpeg2 playback
+ * Provides comprehensive OSD (On Screen Display: ie. graphics overlaying the
+ video signal)
+ * Provides a framebuffer (allowing X applications to appear on the video
+ device) (this framebuffer is not yet part of the kernel. In the meantime it
+ is available from www.ivtvdriver.org).
+ * Supports raw YUV output.
+
+IMPORTANT: In case of problems first read this page:

+
+Devices
+=======
+
+A maximum of 12 ivtv boards are allowed at the moment.
+
+Cards that don't have a video output capability (i.e. non PVR350 cards)
+lack the vbi8, vbi16, video16 and video48 devices. They also do not
+support the framebuffer device /dev/fbx for OSD.
+
+The radio0 device may or may not be present, depending on whether the
+card has a radio tuner or not.
+
+Here is a list of the base v4l devices:
+crw-rw---- 1 root video 81, 0 Jun 19 22:22 /dev/video0
+crw-rw---- 1 root video 81, 16 Jun 19 22:22 /dev/video16
+crw-rw---- 1 root video 81, 24 Jun 19 22:22 /dev/video24
+crw-rw---- 1 root video 81, 32 Jun 19 22:22 /dev/video32
+crw-rw---- 1 root video 81, 48 Jun 19 22:22 /dev/video48
+crw-rw---- 1 root video 81, 64 Jun 19 22:22 /dev/radio0
+crw-rw---- 1 root video 81, 224 Jun 19 22:22 /dev/vbi0
+crw-rw---- 1 root video 81, 228 Jun 19 22:22 /dev/vbi8
+crw-rw---- 1 root video 81, 232 Jun 19 22:22 /dev/vbi16
+
+Base devices
+============
+
+For every extra card you have the numbers increased by one. For example,
+/dev/video0 is listed as the 'base' encoding capture device so we have:
+
+ /dev/video0 is the encoding capture device for the first card (card 0)
+ /dev/video1 is the encoding capture device for the second card (card 1)
+ /dev/video2 is the encoding capture device for the third card (card 2)
+
+Note that if the first card doesn't have a feature (eg no decoder, so no
+video16, the second card will still use video17. The simple rule is 'add
+the card number to the base device number'. If you have other capture
+cards (e.g. WinTV PCI) that are detected first, then you have to tell
+the ivtv module about it so that it will start counting at 1 (or 2, or
+whatever). Otherwise the device numbers can get confusing. The ivtv
+'ivtv_first_minor' module option can be used for that.
+
+
+/dev/video0
+The encoding capture device(s).
+Read-only.
+
+Reading from this device gets you the MPEG1/2 program stream.
+Example:
+
+cat /dev/video0 > my.mpg (you need to hit ctrl-c to exit)
+
+
+/dev/video16
+The decoder output device(s)
+Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
+
+An mpeg2 stream sent to this device will appear on the selected video
+display, audio will appear on the line-out/audio out. It is only
+available for cards that support video out. Example:
+
+cat my.mpg >/dev/video16
+
+
+/dev/video24
+The raw audio capture device(s).
+Read-only
+
+The raw audio PCM stereo stream from the currently selected
+tuner or audio line-in. Reading from this device results in a raw
+(signed 16 bit Little Endian, 48000 Hz, stereo pcm) capture.
+This device only captures audio. This should be replaced by an ALSA
+device in the future.
+Note that there is no corresponding raw audio output device, this is
+not supported in the decoder firmware.
+
+
+/dev/video32
+The raw video capture device(s)
+Read-only
+
+The raw YUV video output from the current video input. The YUV format
+is non-standard (V4L2_PIX_FMT_HM12).
+
+Note that the YUV and PCM streams are not synchronized, so they are of
+limited use.
+
+
+/dev/video48
+The raw video display device(s)
+Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
+
+Writes a YUV stream to the decoder of the card.
+
+
+/dev/radio0
+The radio tuner device(s)
+Cannot be read or written.
+
+Used to enable the radio tuner and tune to a frequency. You cannot
+read or write audio streams with this device. Once you use this
+device to tune the radio, use /dev/video24 to read the raw pcm stream
+or /dev/video0 to get an mpeg2 stream with black video.
+
+
+/dev/vbi0
+The 'vertical blank interval' (Teletext, CC, WSS etc) capture device(s)
+Read-only
+
+Captures the raw (or sliced) video data sent during the Vertical Blank
+Interval. This data is used to encode teletext, closed captions, VPS,
+widescreen signalling, electronic program guide information, and other
+services.
+
+
+/dev/vbi8
+Processed vbi feedback device(s)
+Read-only. Only present if the MPEG decoder (i.e. CX23415) exists.
+
+The sliced VBI data embedded in an MPEG stream is reproduced on this
+device. So while playing back a recording on /dev/video16, you can
+read the embedded VBI data from /dev/vbi8.
+
+
+/dev/vbi16
+The vbi 'display' device(s)
+Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
+
+Can be used to send sliced VBI data to the video-out connector.
