In fact, I personally _want_ signed kernel modules, and still the option to run kexec. kexec is to run a whole new kernel/OS, not a tiny kernel module. If you apply this, you break everyone who is currently relying on kexec (i.e. kdump, bootloaders, etc.), from using signed kernel modules, which personally, seems like a very bad idea. Please just rely on the existing permission checks for kexec, to add on another layer of restrictions seems unneeded, and will force some users to have to patch this out. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-efi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
