From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jianfeng Tan Subject: [PATCH 3/3] net/virtio-user: fix not proper initialized Date: Mon, 12 Feb 2018 03:20:28 +0000 Message-ID: <1518405628-23976-4-git-send-email-jianfeng.tan@intel.com> References: <1518405628-23976-1-git-send-email-jianfeng.tan@intel.com> Cc: yliu@fridaylinux.org, maxime.coquelin@redhat.com, tiwei.bie@intel.com, Jianfeng Tan , stable@dpdk.org To: dev@dpdk.org Return-path: In-Reply-To: <1518405628-23976-1-git-send-email-jianfeng.tan@intel.com> List-Id: DPDK patches and discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dev-bounces@dpdk.org Sender: "dev" intr_handle->fd was wrongly initialized as 0 (usually as the stdio fd) when virtio-user is used with vhost-kernel. So the interrupt thread might wrongly treat stdin events as LSC interrupts.
