SYNOPSIS

#include <sys/param.h>
#include <bsm/audit.h>

int auditon( int cmd, caddr_t data, int length);

AVAILABILITY

The functionality described in this man page is available only if the Basic Security Module (BSM) has been enabled. See bsmconv(1M) for more information.

DESCRIPTION

The auditon(2) system call performs various audit subsystem control operations. The cmd argument designates the particular audit control command. The data argument is a pointer to command specific data. The length argument is the length in bytes of the command specific data.

The following commands are supported:

A_GETCOND

Returns the system audit on/off/disabled condition in the integer long pointed to by data.

A_SETCOND

Sets the system's audit on/off condition to the value in the integer long pointed to by data. If the current state is disabled, the BSM audit module must be enabled by bsmconv(1M) before auditing can be turned on.

A_GETCLASS

Returns the event to class mapping for the designated audit event. The data argument points to the au_evclass_map structure containing the event number. The preselection class mask is returned in the same structure.

A_SETCLASS

Sets the event class preselection mask for the designated audit event. The data argument points to the au_evclass_map structure containing the event number and class mask.

A_GETKMASK
        Returns the kernel preselection mask in the au_mask structure pointed to by data.

A_SETKMASK

Sets the kernel preselection mask. The data argument points to the au_mask structure containing the class mask.

A_GETPINFO

Returns the audit ID, preselection mask, terminal ID and audit session ID of the specified process in the auditpinfo structure pointed to by data.

A_SETPMASK

Sets the preselection mask of the specified process. The data argument points to the auditpinfo structure containing the process ID and the preselection mask.

A_SETUMASK

Sets the preselection mask for all processes with the specified audit ID. The data argument points to the auditinfo structure containing the audit ID and the preselection mask.

A_SETSMASK

Sets the preselection mask for all processes with the specified audit session ID. The data argument points to the auditinfo structure containing the audit session ID and the preselection mask.

A_GETQCTRL

Returns the kernel audit queue control parameters. These control the high and low water marks of the number of audit records allowed in the audit queue. Another parameter controls the size of the data buffer used by auditsvc(2) to write data to the audit trail. There is also a parameter that specifies a delay before data is written to the audit trail. The audit queue parameters are returned in the au_qctrl structure pointed to by data.

A_SETQCTRL
        Sets the kernel audit queue control parameters. The data argument points to the
        au_qctrl structure containing the audit queue control parameters.

A_GETCWD

Returns the current working directory as kept by the audit subsystem. This is a path anchored on the real root, rather than on the active root. The data argument points to a buffer into which the path is copied. The length argument provides the length of the buffer.

A_GETCAR

Returns the current active root as kept by the audit subsystem. This path may be used to anchor an absolute path for a path token generated by an application. The data argument points to a buffer into which the path is copied. The length argument provides the length of the buffer.

A_GETSTAT
        Returns the system audit statistics in the audit_stat structure pointed to by data.

A_SETSTAT

Resets system audit statistics values.

A_GETPOLICY
        Returns the audit policy flags in the integer long pointed to by data.

A_SETPOLICY

Sets the audit policy flags to the values in the integer long pointed to by data. The following policy flags are recognized:

AUDIT_CNT

Do not suspend processes when audit storage is full or inaccessible. The default action is to suspend processes until storage

becomes available.

AUDIT_ARGV Include the argument list for the exec(2) system call in the audit

record. The default action is not to include this information.

AUDIT_ARGE

Include the environment variables for the execv (2)system call in the audit record. The default action is not to include this information.

AUDIT_SEQ

Add a sequence token to each audit record. The default action is not to include it.

AUDIT_TRAIL Append a trailer token to each audit record. The default action is

not to include it.

AUDIT_GROUP

Include the supplementary groups list in audit records. The

default action is not to include it.

AUDIT_PATH

Include secondary paths in audit records. Examples of secondary paths are dynamically loaded shared library modules and the command shell path for executable scripts.

Only the super-user may successfully execute this call.

RETURN VALUES

auditon( ) returns:

0

on success.

-1

on failure and sets errno to indicate the error.

ERRORS

EFAULT

The copy of data to/from the kernel failed.

EINVAL

One of the system call arguments was illegal.

EPERM

The process's effective user ID is not super-user.
