From mboxrd@z Thu Jan 1 00:00:00 1970 From: Huawei Xie Subject: [PATCH] lib/librte_vhost: remove vhost device from data plane when receive VHOST_SET_MEM_TABLE message Date: Tue, 3 Mar 2015 10:26:04 +0800 Message-ID: <1425349564-30489-1-git-send-email-huawei.xie@intel.com> To: dev-VfR2kkLFssw@public.gmane.org Return-path: List-Id: patches and discussions about DPDK List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dev-bounces-VfR2kkLFssw@public.gmane.org Sender: "dev" This patch fixes the segfault issue in the case vhost receives new VHOST_SET_MEM_TABLE message without VHOST_VRING_GET_VRING_BASE(which we uses as the stop message).
