Regarding the table length sanity check -- depth is set to the number of acp_pci_path structures in the table. But then we only follow the path to depth-1. Is that correct? Also I changed the test to '--depth >= 0' which is equivalent and a bit easier to read imo. -- Keir On 2/4/08 17:58, "Espen Skoglund" <espen.skoglund@xxxxxxxxxxxxx> wrote: > Parsing ACPI related VT-d tables may cause infinite loop due to u8 > value wraparound.
