kernel_recvmsg - Receive a message from a socket (kernel space) : The socket to receive the message from : Received message : Input s/g array for message data : Size of input s/g array : Number of bytes to read : Message flags (MSG_DONTWAIT, etc...)

On return the msg structure contains the scatter/gather array passed in the vec argument. The array is modified so that it consists of the unfilled portion of the original array.

The returned value is the total number of bytes received, or an error.

move_addr_to_kernel - copy a socket address into kernel space : Address in user space : Address in kernel space : Length in user space

The address is copied into kernel space. If the provided address is too long an error code of -EINVAL is returned. If the copy gives invalid addresses -EFAULT is returned. On a success 0 is returned.

sock_register - add a socket protocol handler : description of protocol

This function is called by a protocol handler that wants to advertise its address family, and have it linked into the socket interface. The value ops->family coresponds to the socket system call protocol family.

void sock_release

sock_release - close a socket : socket to close

The socket is released from the protocol stack if it has a release callback, and the inode is then released if the socket is bound to an inode not a file.

void sock_unregister

sock_unregister - remove a protocol handler : protocol family to remove

This function is called by a protocol handler that wants to remove its address family, and have it unlinked from the new socket creation.

If protocol handler is a module, then it can use module reference counts to protect against new references. If protocol handler is not a module then it needs to provide its own protection in the ops->create routine.

struct socket* sockfd_lookup ( int  fd, int *  err  )

read

sockfd_lookup - Go from a file number to its socket slot : file handle : pointer to an error code return

The file handle passed in is locked and the socket it is bound too is returned. If an error occurs the err pointer is overwritten with a negative errno code and NULL is returned. The function checks for both invalid handles and passing a handle which is not a socket.

On a success the socket object pointer is returned.
