Matan Barak c66db31113 IB/uverbs: Safely extend existing attributes ... Previously, we've used UVERBS_ATTR_SPEC_F_MIN_SZ for extending existing attributes. The behavior of this flag was the kernel accepts anything bigger than the minimum size it specified. This is unsafe, since in order to safely extend an attribute, we need to make sure unknown size is zeroed. Replacing UVERBS_ATTR_SPEC_F_MIN_SZ with UVERBS_ATTR_SPEC_F_MIN_SZ_OR_ZERO, which essentially checks that the unknown size is zero. In addition, attributes are now decorated with UVERBS_ATTR_TYPE and UVERBS_ATTR_STRUCT, so we can provide the minimum and known length. Users of this flag needs to use copy_from_or_zero functions/macros.
