Eric Biggers 894a02236d ext4: report correct st_size for encrypted symlinks ... commit 8c4bca10ceafc43b1ca0a9fab5fa27e13cbce99e upstream. The stat() family of syscalls report the wrong size for encrypted symlinks, which has caused breakage in several userspace programs. Fix this by calling fscrypt_symlink_getattr() after ext4_getattr() for encrypted symlinks. This function computes the correct size by reading and decrypting the symlink target (if it's not already cached). For more details, see the commit which added fscrypt_symlink_getattr().
