[lsm] Kernel panic - not syncing: Could not register security module
by Fengguang Wu
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git lsm/mnt-restrict
commit 3d916db0f37e377a84754131fea74ff022810e80
Author: Kees Cook <keescook(a)chromium.org>
AuthorDate: Sat Sep 21 15:52:51 2013 -0700
Commit: Kees Cook <keescook(a)chromium.org>
CommitDate: Thu Oct 16 13:22:15 2014 -0700
LSM: MntRestrict blocks mounts on symlink targets
On systems where certain filesystem contents cannot be entirely trusted,
it is beneficial to block mounts on symlinks. This makes sure that
malicious filesystem contents cannot trigger the over-mounting of trusted
filesystems. (For example, a bind-mounted subdirectory of /var cannot be
redirected to mount on /etc via a symlink: a daemon cannot elevate privs
to uid-0.)
