NAME

tsol_get_strattr, tsol_set_strattr- Get security attributes of a message

SYNOPSIS

#include <sys/stream.h>
#include <sys/tsol/tstream.h>

tsol_str_attr * tsol_get_strattr(mblk_t * mp);
void tsol_set_strattr(mblk_t * mp, tsol_strattr_t * strattr);

PARAMETERS

mp

Pointer to message block

strattr

Pointer to a STREAMS attributes structure

DESCRIPTION

tsol_get_strattr() is called by a STREAMS routine to find the attributes attached to a STREAMS message. tsol_get_strattr() returns a pointer to the first attibute structure found. The attribute-structure reference count will be increased to prevent the structure's being released. A module using this routine must call the SATTR_RELE macro to free the attribute structure. If no attribute structure is found in a message, NULL is returned.

tsol_set_strattr() replaces the current set of STREAMS attributes in the message to which mp points with new attributes supplied by strattr . If either mp or strattr is set to NULL , the function exits without changing mp .

ATTRIBUTES

See attributes(5) for descriptions of the following attributes:

ATTRIBUTE TYPE	ATTRIBUTE VALUE
Availability	Trusted Solaris only
Interface-Level	Architecture-independent

CONTEXT

This routine can be called from the interrupt level. The routine will not sleep. The reference count is protected by a short-term spin-lock mutex.

NOTES

These interfaces are uncommitted. Although they are not expected to change between minor releases of the Trusted Solaris environment, they may.
