https://bugzilla.kernel.org/show_bug.cgi?id=213577 Bug ID: 213577 Summary: kernel_lockdown.7 seems to be incorrect about automatically enabling lockdown mode in secure boot mode Product: Documentation Version: unspecified Hardware: All OS: Linux Status: NEW Severity: normal Priority: P1 Component: man-pages Assignee: documentation_man-pages@kernel-bugs.osdl.org Reporter: peter@typeblog.net Regression: No As of the time of posting, the kernel_lockdown.7 manpage [1] contains a description about how lockdown mode is enabled by default when using EFI secure boot:
On an EFI-enabled x86 or arm64 machine, lockdown will be automatically enabled
if the system boots in EFI Secure Boot mode. I have not followed lockdown development upstream recently, but it seems that as of today the feature described above is still a downstream patch shipped by some distributions like Fedora [2][3]. If this is the case, then including this statement in the man page would be inappropriate, since it would not apply to other distributions such as Arch Linux which do not include said patches.
