Nit: The 'Fixes' tag should go before the SoB. Also, please, either send patches separately, or add a cover letter to the set.

Clang's static analyzer will complain about uninitialized value 'hlen' because we weren't properly checking the error code from a function that would have initialized the value. Instead, add a check for that return code.
