.Os
.Sh NAME
.Nm setaudit ,
.Nm setaudit_addr
.Nd "set audit session state"
.Sh SYNOPSIS
.In bsm/audit.h
.Ft int
.Fn setaudit "auditinfo_t *auditinfo"
.Ft int
.Fn setaudit_addr "auditinfo_addr_t *auditinfo_addr" "u_int length"
.Sh DESCRIPTION
The
.Fn setaudit
system call
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 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 ai_auid
variable contains the audit identifier which is recorded in the audit log for
each event the process caused.
.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_termid_t
data structure 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
.PP
The
.Fa ai_asid
variable contains the audit session ID which is recorded with every event
caused by the process.
.Pp
The
.Fn setaudit_addr
system call
uses the expanded
.Fa auditinfo_addr_t
data structure supports Terminal IDs with larger 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. */
};
typedef struct auditinfo_addr auditinfo_addr_t;
.in
.fi
.Pp
The
.Fa au_tid_addr_t
data structure which 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
These system calls require an appropriate privilege to complete.
.Sh RETURN VALUES
.Rv -std setaudit setaudit_addr
.Sh ERRORS
.Bl -tag -width Er
.It Bq Er EFAULT
A failure occurred while data transferred to or from
the kernel failed.
.It Bq Er EINVAL
Illegal argument was passed by a system call.
.It Bq Er EPERM
The process does not have sufficient permission to complete
the operation.

.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.
