LoadPin: Ignore the "contents" argument of the LSM hooks stable inclusion from stable-v5.10.163 commit c3607ed7edfb73f194abfe8d5bbdb8a857266a1f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7PJ9N Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=c3607ed7edfb73f194abfe8d5bbdb8a857266a1f ---------------------------------------------------- [ Upstream commit 1a17e5b513ceebf21100027745b8731b4728edf7 ] LoadPin only enforces the read-only origin of kernel file reads. Whether or not it was a partial read isn't important. Remove the overly conservative checks so that things like partial firmware reads will succeed (i.e. reading a firmware header).
