ISCSI_CREATE_CONN(9)						  SCSI mid layer					      ISCSI_CREATE_CONN(9)

NAME

       iscsi_create_conn - create iscsi class connection

SYNOPSIS

       struct iscsi_cls_conn * iscsi_create_conn(struct iscsi_cls_session * session, int dd_size, uint32_t cid);

ARGUMENTS

       session
	   iscsi cls session

       dd_size
	   private driver data size

       cid
	   connection id

DESCRIPTION

       This can be called from a LLD or iscsi_transport. The connection is child of the session so cid must be unique for all connections on the
       session.

       Since we do not support MCS, cid will normally be zero. In some cases for software iscsi we could be trying to preallocate a connection
       struct in which case there could be two connection structs and cid would be non-zero.

NAME

       cmpt_get_peer_cid(), cmpt_get_endpoint_cid() - get the compartment IDs for INET domain communications.

SYNOPSIS


   Parameters
	      s      INET domain socket or stream.

DESCRIPTION

       The and functions return the compartments associated with an INET domain transport endpoint (a socket or a stream).

       The  function  returns  the  compartment  ID (cid) associated with the transport endpoint s.  The cid of a transport endpoint is set to the
       process's cid at the time of creation, and does not change even when it is transferred between processes or the	creating  process  changes
       its compartment.

       The  function returns the compartment ID of the peer that the transport endpoint s is communicating with.  For loopback communications, the
       cid is the one associated with the peer transport endpoint.  For communications over a network interface, the peer cid is the  one  associ-
       ated with the network interface where communications are being received.  For TCP communications, the peer cid is persistent once a connec-
       tion is established.  For other protocols, the peer cid may change for each packet that is received.

       The function returns an error if a connection is not established (for TCP) or no communication has been received (for all other protocols).

RETURN VALUE

       and return the following values:

	      Successful completion.
		      The function returns a valid compartment ID.

	      Function failed.
		      is set to indicate the error from the underlying system call.
