| A_SETPOLICY
|
Set audit policy flags.
The
data
argument
must point to a
int
value set to one or more the following audit
policy control values bitwise OR'ed together:
AUDIT_CNT,
AUDIT_AHLT,
AUDIT_ARGV,
and
AUDIT_ARGE.
If
AUDIT_CNT is set, the system will continue even if it becomes low
on space and discontinue logging events until the low space condition is
remedied.
If it is not set, audited events will block until the low space
condition is remedied.
Unaudited events, however, are unaffected.
If
AUDIT_AHLT is set, a
panic(9)
if it cannot write an event to the global audit log file.
If
AUDIT_ARGV
is set, then the argument list passed to the
execve(2)
system call will be audited.
If
AUDIT_ARGE
is set, then the environment variables passed to the
execve(2)
system call will be audited.
The default policy is none of the audit policy
control flags set.
|
| A_SETKAUDIT
|
Set the host information.
The
data
argument
must point to a
auditinfo_addr_t
structure containing the host IP address information.
After setting, audit records
that are created as a result of kernel events will contain
this information.
|
| A_SETKMASK
|
Set the kernel preselection masks (success and failure).
The
data
argument
must point to a
au_mask_t
structure containing the mask values as defined in
<bsm/audit.h>.
These masks are used for non-attributable audit event preselection.
The field
am_success
specifies which classes of successful audit events are to be logged to the
audit trail.
The field
am_failure
specifies which classes of failed audit events are to be logged.
The value of
both fields is the bitwise OR'ing of the audit event classes specified in
bsm/audit.h.
The various audit classes are described more fully in
audit_class(5).
|
| A_SETQCTRL
|
Set kernel audit queue parameters.
The
data
argument
must point to a
au_qctrl_t
structure (defined in
<bsm/audit.h>)
containing the kernel audit queue control settings:
aq_hiwater,
aq_lowater,
aq_bufsz,
aq_delay,
and
aq_minfree.
The field
aq_hiwater
defines the maximum number of audit record entries in the queue used to store
the audit records ready for delivery to disk.
New records are inserted at the tail of the queue and removed from the head.
For new records which would exceed the
high water mark, the calling thread is inserted into the wait queue, waiting
for the audit queue to have enough space available as defined with the field
aq_lowater.
The field
aq_bufsz
defines the maximum length of the audit record that can be supplied with
audit(2).
The field
aq_delay
is unused.
The field
aq_minfree
specifies the minimum amount of free blocks on the disk device used to store
audit records.
If the value of free blocks falls below the configured
minimum amount, the kernel informs the audit daemon about low disk space.
The value is to be specified in percent of free file system blocks.
A value of 0 results in a disabling of the check.
The default and maximum values (default/maximum) for the
audit queue control parameters are:
aq_hiwater | 100/10000 (audit records) |
aq_lowater | 10/aq_hiwater (audit records) |
aq_bufsz | 32767/1048576 (bytes) |
aq_delay | (Not currently used.) |
|

|
| A_SETCOND
|
Set the current auditing condition.
The
data
argument
must point to a
int
value containing the new
audit condition, one of
AUC_AUDITING,
AUC_NOAUDIT,
or
AUC_DISABLED.
If
AUC_NOAUDIT
is set, then auditing is temporarily suspended.
If
AUC_AUDITING
is set, auditing is resumed.
If
AUC_DISABLED
is set, the auditing system will
shutdown, draining all audit records and closing out the audit trail file.
|
| A_SETCLASS
|
Set the event class preselection mask for an audit event.
The
data
argument
must point to a
au_evclass_map_t
structure containing the audit event and mask.
The field
ec_number
is the audit event and
ec_class
is the audit class mask.
See
audit_event(5)
for more information on audit event to class mapping.
|
| A_SETPMASK
|

The
data
argument

preselection masks for both success and failure.
