  • 611561983   ANDROID: AVB error handler to invalidate vbmeta partition. ... Browse Code ยป

    If androidboot.vbmeta.invalidate_on_error is 'yes' and
    androidboot.vbmeta.device is set and points to a device with vbmeta
    magic, this header will be overwritten upon an irrecoverable dm-verity
    error. The side-effect of this is that the slot will fail to verify on
    next reboot, effectively triggering the boot loader to fallback to
    another slot. This work both if the vbmeta struct is at the start of a
    partition or if there's an AVB footer at the end.

    This code is based on drivers/md/dm-verity-chromeos.c from ChromiumOS.
