-Subject: [PATCH] ehci: make idt processing more robust
-
-Make ehci_process_itd return an error in case we didn't do any actual
-iso transfer because we've found no active transaction. That'll avoid
-ehci happily run in circles forever if the guest builds a loop out of
-idts.
-
-This is CVE-2015-8558.
