This audit record will contain a header, subject token, an optional text token, return token, and a trailer. The header will contain the event class specified by .Fa au_event . The subject token will be generated based on .Fa auid . The return token is dependent on the .Fa status and .Fa reterr arguments; unlike the argument to .Xr au_to_return , .Fa reterr should be a local rather than BSM error number. Optionally, a text token will be created as a part of this record. .Pp Text token output is under the control of a .Fa format string that specifies how subsequent arguments (or arguments accessed via the variable-length argument facilities of .Xr stdarg 3 ) are converted for output. If .Fa format is .Dv NULL , then no text token is created in the audit record. .Pp It should be noted that .Fn audit_submit assumes that .Xr setaudit 2 , or .Xr setaudit_addr 2 has already been called. As a direct result, the terminal ID for the subject will be retrieved from the kernel via .Xr getaudit 2 , or .Xr getaudit_addr 2 . .Sh RETURN VALUES If successful, .Nm will return zero. Otherwise a -1 is returned and the global variable .Va errno is set to indicate the error. .Sh EXAMPLES .Bd -literal -offset indent #include #include #include #include #include #include void audit_bad_su(char *from_login, char *to_login) { struct auditinfo_addr aia; struct auditinfo ai; au_id_t aid; int error; error = getaudit_addr(&aia, sizeof(aia)); if (error < 0 && errno == ENOSYS) { error = getaudit(&ai); if (error < 0) err(1, "getaudit"); aid = ai.ai_auid; } else if (error < 0) err(1, "getaudit_addr"); else aid = aia.ai_auid; error = audit_submit(AUE_su, aid, EPERM, 1, "bad su from %s to %s", from_login, to_login); if (error != 0) err(1, "audit_submit"); } .Ed .Pp Will generate the following audit record: .Bd -literal -offset indent 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 .Ed .Sh SEE ALSO .Xr auditon 2 , .Xr getaudit 2 , .Xr libbsm 3 , .Xr stdarg 3 .Sh HISTORY The .Fn audit_submit function first appeared in OpenBSM version 1.0.
