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
     successful; 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.
