Modified Files: src/sys/dev/pci: pciide_piix_reg.h Log Message: Avoid undefined behavior in pciiide macros Cast the 'bytes' argument in PIIX_IDETIM_SET() and PIIX_IDETIM_CLEAR() to unsigned int. This prevents UB because of shifting the bits and changing the bit of signedness. sys/dev/pci/piixide.c:714:11, left shift of 65535 by 16 places cannot be represented in type 'int' sys/dev/pci/piixide.c:720:11, left shift of 32768 by 16 places cannot be represented in type 'int' Detected with Kernel Undefined Behavior Sanitizer.
