I think that's a starting point, but it doesn't seem sufficient for some of the cases I care about. For instance, measuring boot state isn't just about the files that are read - we also need to measure the commands that grub runs and the command line passed to the kernel, for instance. Ideally we'd also have more context available in order to make a better decision about which PCR to measure something into, but I can't think of a good way to do that simply by hooking open. That also seems to make it difficult to implement a handler that should only be verifying some objects - for instance, a UEFI secure boot handler only wants to verify the kernel (or something that's chainloaded) and ignore everything else. -- Matthew Garrett | mj...@srcf.ucam.org _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
