From 7c211eb078c42146ee9a441cc028fbc4c378ef5a Mon Sep 17 00:00:00 2001 From: BillXiang Date: Thu, 13 Jun 2024 14:51:50 +0800 Subject: [PATCH] vhost-user: Skip unnecessary duplicated VHOST_USER_SET_LOG_BASE requests The VHOST_USER_SET_LOG_BASE requests should be categorized into non-vring specific messages, and should be sent only once. If send more than once, dpdk will munmap old log_addr which may has been used and cause segmentation fault.
