Here are the fixes for zero-length commands, that ultimately let all command go through normal processing, even if they have zero length. The first patch is for PSCSI, the others are for IBLOCK and friends. I tried to order them so that the safest come first. So for 3.6 you could choose to stop at patch 1, 2, 3 or 6, or not apply anything at all. Testcases included in each patch, when relevant.
