raw_usrreq Kernel Service

Implements user requests for raw protocols.

#include <sys/types.h>
#include <sys/errno.h>

void raw_usrreq (so, req, m, nam, control) struct socket * so; int req; struct mbuf * m; struct mbuf * nam; struct mbuf * control;

so	Identifies the address of a raw socket.
req	Specifies the request command.
m	Specifies the address of an mbuf structure containing data.
nam	Specifies the address of an mbuf structure containing the sockaddr structure.
control	This parameter should be set to a null value.

The raw_usrreq kernel service implements user requests for the raw protocol.

The raw_usrreq service supports the following commands:

Command	Description
PRU_ABORT	Aborts (fast DISCONNECT, DETACH).
PRU_ACCEPT	Accepts connection from peer.
PRU_ATTACH	Attaches protocol to up.
PRU_BIND	Binds socket to address.
PRU_CONNECT	Establishes connection to peer.
PRU_CONNECT2	Connects two sockets.
PRU_CONTROL	Controls operations on protocol.
PRU_DETACH	Detaches protocol from up.
PRU_DISCONNECT	Disconnects from peer.
PRU_LISTEN	Listens for connection.
PRU_PEERADDR	Fetches peer's address.
PRU_RCVD	Have taken data; more room now.
PRU_RCVOOB	Retrieves out of band data.
PRU_SEND	Sends this data.
PRU_SENDOOB	Sends out of band data.
PRU_SENSE	Returns status into m.
PRU_SOCKADDR	Fetches socket's address.
PRU_SHUTDOWN	Will not send any more data.

Any unrecognized command causes the panic kernel service to be called.

The raw_userreq kernel service can be called from either the process or interrupt environment.

EOPNOTSUPP	Indicates an unsupported command.
EINVAL	Indicates a parameter error.
EACCESS	Indicates insufficient authority to support the PRU_ATTACH command.
ENOTCONN	Indicates an attempt to detach when not attached.
EISCONN	Indicates that the caller tried to connect while already connected.
