I do think it's handled by patch
"Only match pe_data created by the same pe"

Do you mean that IP_VS_DBG should be replaced ?
if (pe_data_len) {
if (pe_name_len) {
...
} else {
IP_VS_DBG(3, "BACKUP, Invalid PE parameters\n");

OK, I'll do that
i.e. we should accept the result of: "pe or name is null" as a BUG...
