+.Os
+.Sh NAME
+.Nm setaudit_addr ,
+.Nm setaudit(NOW DEPRECATED)
+.Nd "set audit session state"
+.Sh SYNOPSIS
+.In bsm/audit.h
+.In bsm/audit_session.h
+.Ft int
+.Fn setaudit_addr "auditinfo_addr_t *auditinfo_addr" "u_int length"
+.Sh SYNOPSIS (NOW DEPRECATED)
+.In bsm/audit.h
+.Ft int
+.Fn setaudit "auditinfo_t *auditinfo"
+.Sh DESCRIPTION
+The
+.Fn setaudit_addr
+system call
+uses the
+.Fa auditinfo_addr_t
+data structure for the
+.Fa auditinfo_addr
+argument which supports Terminal IDs with large addresses
+such as those used in IP version 6. It is defined as follows:
+.nf
+.in +4n
+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. */
+ u_int64_t ai_flags; /* Audit session flags */
+};
+typedef struct auditinfo_addr auditinfo_addr_t;
+.in
+.fi
+.Pp
+The
+.Fa ai_auid
+variable contains the audit identifier which is recorded in the audit log for
+each event the process caused. The value of AU_DEFAUDITID (-1) should not be
+used. The exception is if the value of audit identifier is known at the start
+of the session but will be determined and set later. Until
+.Fa ai_auid
+is set to something other than AU_DEFAUDITID any audit events
+generated by the system with be filtered by the non-attributed audit
+mask.
+.Pp
+The
+.Fa 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:
+.nf
+.in +4n
+struct au_mask {
+ unsigned int am_success; /* success bits */
+ unsigned int am_failure; /* failure bits */
+};
+typedef struct au_mask au_mask_t;
+.in
+.fi
+.Pp
+The
+.Fa au_tid_addr_t
+data structure includes a larger address storage field and an additional
+field with the type of address stored:
+.nf
+.in +4n
+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;
+.in
+.fi
+.Pp
+The
+.Fa ai_asid
+variable contains the audit session ID which is recorded with every event
+caused by the process. It can be any value in the range 1 to PID_MAX (99999).
+If the value of AU_ASSIGN_ASID is used for
+.Fa ai_asid
+a unique session ID will be generated by the kernel.
+The audit session ID will be returned in the
+.Fa ai_asid
+field on success.
+.Pp
+The
+.Fa ai_flags
+field is opaque to the kernel and can be used to store flags associated
+with the audit session. Please see the
+.Ao Pa bsm/audit_session.h Ac
+header file
+for more infomration and flag definitions for this platform.
+.Pp
+The
+.Fa setaudit_addr
+system call require an appropriate privilege to complete.
+.Pp
+This system call should only be called once at the start of a new
+session and not again during the same session to update the session
+information.
+There are some exceptions, however.
+The
+.Fa ai_auid
+field may be updated later if initially set to the value of
+AU_DEFAUDITID (-1).
+Likewise, the
+.Fa ai_termid
+fields may be updated later if the
+.Fa at_type
+field in
+.Fa au_tid_addr
+is set to AU_IPv4 and the other
+.Fa ai_tid_addr
+fields are all set to zero.
+Creating a new session is done by setting the
+.Fa ai_asid
+field to an unique session value or AU_ASSIGN_ASID.
+These system calls will fail when attempting to change the
+.Fa ai_auid
+or
+.Fa ai_termid
+fields once set to something other than the default values.
+The
+.Fa ai_flags
+field may be updated only according to local access control
+policy but this is usually accomplished with
+.Xr auditon 2
+using the A_SETSFLAGS command.
+The audit preselection masks may be changed at any time
+but are usually updated with
+.Xr auditon 2
+.Pp
+The
+.Fn setaudit
+system call (NOW DEPRECATED)
+sets the active audit session state for the current process via the
+.Vt auditinfo_t
+pointed to by
+.Fa auditinfo .
+The
+.Fn setaudit_addr
+system call
+sets extended state via
+.Fa auditinfo_addr
+and
+.Fa length .
+.Pp
+The
+.Fa auditinfo_t
+data structure (NOW DEPRECATED) is defined as follows:
+.nf
+.in +4n
+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;
+.in
+.fi
+.Pp
+The
+.Fa au_termid_t
+data structure (NOW DEPRECATED) defines the Terminal ID recorded with every
+event caused by the process. It is defined as follows:
+.nf
+.in +4n
+struct au_tid {
+ dev_t port;
+ u_int32_t machine;
+};
+typedef struct au_tid au_tid_t;
+.in
+.fi
+.Sh RETURN VALUES

+the kernel failed.

+.Sh 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.
+.Pp
+.Fn setaudit_addr
+replaced
+.Fn setaudit
+in Mac OS X 10.7 to support longer terminal addresses such as those used
+by IP version 6.
+.Fn setaudit
+is now deprecated and
+.Fn setaudit_addr
+should be used instead.
