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

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 .

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

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:

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

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

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:

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 Fa 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

Rv -std setaudit setaudit_addr

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.
