X-Received-From: 2607:f8b0:4864:20::630 X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: dereksu@qnap.com, chen.zhang@intel.com, jasowang@redhat.com, lizhijian@cn.fujitsu.com Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" The patch is to fix the memory leak in packet_enqueue(). The allocated "pkt" needs to be freed if the colo compare primary or secondary queue is too big to insert. Reproduce steps: (1) Setup PVM and SVM both with NIC e1000 by the steps descripted in the wiki qemu/COLO (2) Run "iperf3 -s" in PVM (3) Run "iperfs -c -t 7200" The memory usage of qemu-system-x86_64 increases as the PVM's QMP shows "qemu-system-x86_64: colo compare secondary queue size too big, drop packet". Please review, thanks.
