Here are steps to reproduce (on both 3.2.37 and 3.7.3, with selinux, on an ext4 fs): 0 - have a regular file "f", with a "before_t" security.selinux attribute 1 - reboot with selinux=0 2 - change the label to "after_t" (setfattr or chcon) 3 - both "ls -Z" (who calls lgetxattr(2)) and "getfattr -n security.selinux" (who calls getxattr(2)) show "after_t" 4 - reboot with selinux enabled 5 - now ls prints "before_t", and getfattr "after_t". I ran a small test that calls both syscalls (lgetxattr/getxattr), I get "before_t" as expected If I touch /.autorelabel, both ls/getfattr give "before_t". -- Thomas Coudray -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
