audit_submit(3) FreeBSD Library Functions Manual audit_submit(3)
NAME
audit_submit -- general purpose audit record submission
LIBRARY
Basic Security Module User Library (libbsm, -lbsm)
SYNOPSIS
#include <bsm/libbsm.h>
int
audit_submit(short au_event, au_id_t auid, char status, int reterr,
const char * restrict format, ...);
DESCRIPTION
The audit_submit() function provides a generic programming interface for
audit record submission. This audit record will contain a header, sub-
ject token, an optional text token, return token, and a trailer. The
header will contain the event class specified by au_event. The subject
token will be generated based on au_ctx. The return token is dependent
on the status and reterr arguments. Optionally, a text token will be
created as a part of this record.
Text token output is under the control of a format string that specifies
how subsequent arguments (or arguments accessed via the variable-length
argument facilities of stdarg(3)) are converted for output. If format is
NULL, then no text token is created in the audit record.
It should be noted that audit_submit() assumes that setaudit(2), or
setaudit_addr(2) has already been called. As a direct result, the termi-
nal ID for the subject will be retrieved from the kernel via getaudit(2),
or getaudit_addr(2).
EXAMPLES
#include <bsm/audit.h>
#include <bsm/libbsm.h>
#include <bsm/audit_uevents.h>
#include <stdio.h>
#include <stdarg.h>
#include <errno.h>
int
audit_bad_su(char *from_login, char *to_login)
{
int error;
error = audit_submit(AUE_su, getuid(), 1, EPERM,
"bad su from %s to %s", from_login, to_login);
return (error);
}
Will generate the following audit record:
header,94,1,su(1),0,Mon Apr 17 23:23:59 2006, + 271 msec
subject,root,root,wheel,root,wheel,652,652,0,0.0.0.0
text,bad su from from csjp to root
return,failure : Operation not permitted,1
trailer,94
