    NAME

    
    
    auditon
    
     - configure system audit parameters
    
     
    

    SYNOPSIS

       #include <bsm/audit.h>
    int auditon (int cmd void *data u_int length);
     

    DESCRIPTION

    The auditon ();
    system call is used to manipulate various audit control operations. The Fa data argument should point to a structure whose type depends on the command. The Fa length argument specifies the size of Fa *data in bytes. The Fa cmd argument may be any of the following:

    A_SETPOLICY
    Set audit policy flags. The Fa data argument must point to a Vt long value set to one of the audit policy control values defined in In bsm/audit.h . Currently, only AUDIT_CNT and AUDIT_AHLT are implemented.    #include <the>
    AUDIT_CNT case, the action will continue regardless if an event will not be audited.    #include <the>
    AUDIT_AHLT case, a panic(9) will result if an event will not be written to the audit log file.
    A_SETKAUDIT
    Return Er ENOSYS .
    A_SETKMASK
    Set the kernel preselection masks (success and failure). The Fa data argument must point to a Vt au_mask_t structure containing the mask values. These masks are used for non-attributable audit event preselection.
    A_SETQCTRL
    Set kernel audit queue parameters. The Fa data argument must point to a Vt au_qctrl_t structure containing the kernel audit queue control settings: ``high water'' ``low water'' ``output buffer size'' ``percent min free disk space'' and ``delay'' (not currently used).
    A_SETSTAT
    Return Er ENOSYS .
    A_SETUMASK
    Return Er ENOSYS .
    A_SETSMASK
    Return Er ENOSYS .
    A_SETCOND
    Set the current auditing condition. The Fa data argument must point to a Vt long value containing the new audit condition, one of AUC_AUDITING AUC_NOAUDIT or AUC_DISABLED
    A_SETCLASS
    Set the event class preselection mask for an audit event. The Fa data argument must point to a Vt au_evclass_map_t structure containing the audit event and mask.
    A_SETPMASK
    Set the preselection masks for a process. The Fa data argument must point to a Vt auditpinfo_t structure that contains the given process's audit preselection masks for both success and failure.
    A_SETFSIZE
    Set the maximum size of the audit log file. The Fa data argument must point to a Vt au_fstat_t structure with the af_filesz field set to the maximum audit log file size. A value of 0 indicates no limit to the size.
    A_SETKAUDIT
    Return Er ENOSYS .
    A_GETCLASS
    Return the event to class mapping for the designated audit event. The Fa data argument must point to a Vt au_evclass_map_t structure.
    A_GETKAUDIT
    Return Er ENOSYS .
    A_GETPINFO
    Return the audit settings for a process. The Fa data argument must point to a Vt auditpinfo_t structure which will be set to contain the audit ID, preselection mask, terminal ID, and audit session ID of the given process.
    A_GETPINFO_ADDR
    Return Er ENOSYS .
    A_GETKMASK
    Return the current kernel preselection masks. The Fa data argument must point to a Vt au_mask_t structure which will be set to the current kernel preselection masks for non-attributable events.
    A_GETPOLICY
    Return the current audit policy setting. The Fa data argument must point to a Vt long value which will be set to one of the current audit policy flags. Currently, only AUDIT_CNT and AUDIT_AHLT are implemented.
    A_GETQCTRL
    Return the current kernel audit queue control parameters. The Fa data argument must point to a Vt au_qctrl_t structure which will be set to the current kernel audit queue control parameters.
    A_GETFSIZE
    Returns the maximum size of the audit log file. The Fa data argument must point to a Vt au_fstat_t structure. The af_filesz field will be set to the maximum audit log file size. A value of 0 indicates no limit to the size. The af_currsz field will be set to the current audit log file size.
    A_GETCWD
    Return Er ENOSYS .
    A_GETCAR
    Return Er ENOSYS .
    A_GETSTAT
    Return Er ENOSYS .
    A_GETCOND
    Return the current auditing condition. The Fa data argument must point to a Vt long value which will be set to the current audit condition, either AUC_AUDITING or AUC_NOAUDIT
    A_SENDTRIGGER
    Send a trigger to the audit daemon. The Fa data argument must point to a Vt long value set to one of the acceptable trigger values: AUDIT_TRIGGER_LOW_SPACE (low disk space where the audit log resides), AUDIT_TRIGGER_OPEN_NEW (open a new audit log file), AUDIT_TRIGGER_READ_FILE (read the audit_control file), AUDIT_TRIGGER_CLOSE_AND_DIE (close the current log file and exit), or AUDIT_TRIGGER_NO_SPACE (no disk space left for audit log file).

     

    RETURN VALUES

    Rv -std  

    ERRORS

    The auditon ();
    function will fail if:

    Bq Er ENOSYS
    Returned by options not yet implemented.
    Bq Er EFAULT
    A failure occurred while data transferred to or from the kernel failed.
    Bq Er EINVAL
    Illegal argument was passed by a system call.
    Bq Er EPERM
    The process does not have sufficient permission to complete the operation.

    The A_SENDTRIGGER command is specific to the Fx and Mac OS X implementations, and is not present in Solaris.

    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.
