You've added a memset() to clear the scratch memory in bpf_filter(). We had this before... the point of bpf_validate() is to make sure that the filter program doesn't access uninitialized values. The runtime cost of clearing the array can thus be avoided. Or do you have reason to believe that the validator doesn't work as expected? best regards Matthias ------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------ Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
