From dc240913458d591f59b52b3899d3fc3c5d6ec6ce Mon Sep 17 00:00:00 2001 From: Matt Turner Date: Wed, 17 Oct 2018 12:32:54 -0700 Subject: src: Use memcpy() to handle potentially unaligned data Rolf Eike Beer reported that nft-expr_quota-test fails with a SIGBUS on SPARC due to unaligned accesses. This patch resolves that and fixes additional sources of unaligned accesses matching the same pattern. Both nft-expr_quota-test and nft-expr_objref-test generated unaligned accesses on DEC Alpha.
