From: Claudio Imbrenda Date: Wed, 20 Jun 2018 13:51:51 +0000 (+0200) Subject: VSOCK: fix loopback on big-endian systems X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=e5ab564c9ebee77794842ca7d7476147b83d6a27;p=openwrt%2Fstaging%2Fblogic.git VSOCK: fix loopback on big-endian systems The dst_cid and src_cid are 64 bits, therefore 64 bit accessors should be used, and in fact in virtio_transport_common.c only 64 bit accessors are used. Using 32 bit accessors for 64 bit values breaks big endian systems. This patch fixes a wrong use of le32_to_cpu in virtio_transport_send_pkt.
