SETAUDIT(2)		  FreeBSD System Calls Manual		   SETAUDIT(2)

NAME
     setaudit, setaudit_addr --	set audit session state

SYNOPSIS
     #include <bsm/audit.h>

     int
     setaudit(auditinfo_t *auditinfo);

     int
     setaudit_addr(auditinfo_addr_t *auditinfo_addr, u_int length);

DESCRIPTION
     The setaudit() system call	sets the active	audit session state for	the
     current process via the auditinfo_t pointed to by auditinfo.  The
     setaudit_addr() system call sets extended state via auditinfo_addr	and
     length.

     The auditinfo_t data structure is defined as follows:

	 struct	auditinfo {
		 au_id_t	ai_auid;	 /* Audit user ID */
		 au_mask_t	ai_mask;	 /* Audit masks	*/
		 au_tid_t	ai_termid;	 /* Terminal ID	*/
		 au_asid_t	ai_asid;	 /* Audit session ID */
	 };
	 typedef struct	auditinfo	 auditinfo_t;

     The ai_auid variable contains the audit identifier	which is recorded in
     the audit log for each event the process caused.

     The au_mask_t data	structure defines the bit mask for auditing successful
     and failed	events out of the predefined list of event classes. It is
     defined as	follows:

	 struct	au_mask	{
		 unsigned int	 am_success;	 /* success bits */
		 unsigned int	 am_failure;	 /* failure bits */
	 };
	 typedef struct	au_mask	 au_mask_t;

     The au_termid_t data structure defines the	Terminal ID recorded with
     every event caused	by the process.	It is defined as follows:

	 struct	au_tid {
		 dev_t		 port;
		 u_int32_t	 machine;
	 };
	 typedef struct	au_tid	 au_tid_t;

     The ai_asid variable contains the audit session ID	which is recorded with
     every event caused	by the process.

     The setaudit_addr() system	call uses the expanded auditinfo_addr_t	data
     structure supports	Terminal IDs with larger addresses such	as those used
     in	IP version 6.  It is defined as	follows:

	 struct	auditinfo_addr {
		 au_id_t	 ai_auid;	 /* Audit user ID. */
		 au_mask_t	 ai_mask;	 /* Audit masks. */
		 au_tid_addr_t	 ai_termid;	 /* Terminal ID. */
		 au_asid_t	 ai_asid;	 /* Audit session ID. */
	 };
	 typedef struct	auditinfo_addr	 auditinfo_addr_t;

     The au_tid_addr_t data structure which includes a larger address storage
     field and an additional field with	the type of address stored:

	 struct	au_tid_addr {
		 dev_t		 at_port;
		 u_int32_t	 at_type;
		 u_int32_t	 at_addr[4];
	 };
	 typedef struct	au_tid_addr	 au_tid_addr_t;

     These system calls	require	an appropriate privilege to complete.

RETURN VALUES
     The setaudit() and	setaudit_addr()	functions return the value 0 if	suc-
     cessful; otherwise	the value -1 is	returned and the global	variable errno
     is	set to indicate	the error.

ERRORS
     [EFAULT]		A failure occurred while data transferred to or	from
			the kernel failed.

     [EINVAL]		Illegal	argument was passed by a system	call.

     [EPERM]		The process does not have sufficient permission	to
			complete the operation.

HISTORY
     The OpenBSM implementation	was created by McAfee Research,	the security
     division of McAfee	Inc., under contract to	Apple Computer Inc. in 2004.
     It	was subsequently adopted by the	TrustedBSD Project as the foundation
     for the OpenBSM distribution.

AUTHORS
     This software was created by McAfee Research, the security	research divi-
     sion of McAfee, Inc., under contract to Apple Computer Inc.  Additional
     authors include Wayne Salamon, Robert Watson, and SPARTA Inc.

     The Basic Security	Module (BSM) interface to audit	records	and audit
     event stream format were defined by Sun Microsystems.
