openvswitch: fix flow command message size [ Upstream commit 4e81c0b3fa93d07653e2415fa71656b080a112fd ] When user-space sets the OVS_UFID_F_OMIT_* flags, and the relevant flow has no UFID, we can exceed the computed size, as ovs_nla_put_identifier() will always dump an OVS_FLOW_ATTR_KEY attribute. Take the above in account when computing the flow command message size. Fixes: 74ed7ab9264c ("openvswitch: Add support for unique flow IDs.")
