Based on the mailing list discussions, it is clear that separating the non-init unpriviliged, mounted untrusted filesystem from setuid unprivileged or privileged mounted untrusted filesystems patches was confusing. I've combined the patches, commenting the code with an explanation for the differentiation. Instad of expliciting modifying the IMA policy to fail file signature verfication for the setuid unprivileged or privileged mounted untrusted filesystems cases, this patch set defines a builtin IMA policy named "untrusted-fs". No other IMA policy changes are required. Mimi Changelog v1: - Merged the unprivileged and privileged patches. - Dropped IMA fsname support. - Introduced a new IMA builtin policy named "untrusted_fs". - Replaced fs_type flag with sb->s_iflags flag.
