Richard Weinberger 453f2dfa34 ubifs: wbuf: Don't leak kernel memory to flash ... commit 20f1431160c6b590cdc269a846fc5a448abf5b98 upstream. Write buffers use a kmalloc()'ed buffer, they can leak up to seven bytes of kernel memory to flash if writes are not aligned. So use ubifs_pad() to fill these gaps with padding bytes. This was never a problem while scanning because the scanner logic manually aligns node lengths and skips over these gaps.
