.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:
|
|
.Bd -literal -offset 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;
|
|
.Ed
|
|
.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:
|
|
.Bd -literal -offset 4n
|
|
struct au_mask {
|
|
unsigned int am_success; /* success bits */
|
|
unsigned int am_failure; /* failure bits */
|
|
};
|
|
typedef struct au_mask au_mask_t;
|
|
.Ed
|
|
.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:
|
|
.Bd -literal -offset 4n
|
|
struct au_tid {
|
|
dev_t port;
|
|
u_int32_t machine;
|
|
};
|
|
typedef struct au_tid au_tid_t;
|
|
.Ed
|
|
.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:
|
|
.Bd -literal -offset 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;
|
|
.Ed
|
|
.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:
|
|
.Bd -literal -offset 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;
|
|
.Ed
|
|
.Pp
|
|
These system calls require an appropriate privilege to complete.
|
|
.Sh RETURN VALUES
|
|
.Rv -std setaudit setaudit_addr
|
|
.Sh ERRORS
|
|
.Bl -tag -width Er
