doc: ReSTify LoadPin.txt Adjusts for ReST markup and moves under LSM admin guide. Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Jonathan Corbet <corbet@lwn.net> 2017-05-13 04:51:48 -07:00



LSM: LoadPin for kernel file loading restrictions This LSM enforces that kernel-loaded files (modules, firmware, etc) must all come from the same filesystem, with the expectation that such a filesystem is backed by a read-only device such as dm-verity or CDROM. This allows systems that have a verified and/or unchangeable filesystem to enforce module and firmware loading restrictions without needing to sign the files individually.

security/loadpin: Update the changing interface in the source code. Loadpin cmdline interface "enabled" has been renamed to "enforce" for a long time, but the User Description Document was not updated. (Meaning unchanged) And kernel_read_file* were moved from linux/fs.h to its own linux/kernel_read_file.h include file. So update that change here.

security/loadpin: Allow to exclude specific file types Linux kernel already provide MODULE_SIG and KEXEC_VERIFY_SIG to make sure loaded kernel module and kernel image are trusted. This patch adds a kernel command line option "loadpin.exclude" which allows to exclude specific file types from LoadPin. This is useful when people want to use different mechanisms to verify module and kernel image while still use LoadPin to protect the integrity of other files kernel loads.
