Stephen Smalley f549d6c18c [PATCH] Generic VFS fallback for security xattrs ... This patch modifies the VFS setxattr, getxattr, and listxattr code to fall back to the security module for security xattrs if the filesystem does not support xattrs natively. This allows security modules to export the incore inode security label information to userspace even if the filesystem does not provide xattr storage, and eliminates the need to individually patch various pseudo filesystem types to provide such access. The patch removes the existing xattr code from devpts and tmpfs as it is then no longer needed. The patch restructures the code flow slightly to reduce duplication between the normal path and the fallback path, but this should only have one user-visible side effect - a program may get -EACCES rather than -EOPNOTSUPP if policy denied access but the filesystem didn't support the operation anyway. Note that the post_setxattr hook call is not needed in the fallback case, as the inode_setsecurity hook call handles the incore inode security state update directly. In contrast, we do call fsnotify in both cases.
