From a38df1edd6324f922ca46a043e87b2489f7bc17e Mon Sep 17 00:00:00 2001 From: Qiming Chen Date: Sat, 11 Sep 2021 09:47:09 +0800 Subject: [PATCH 1/1] net/iavf: fix mbuf leak A local test found that repeated port start and stop operations during the continuous SSE vector bufflist receiving process will cause the mbuf resource to run out. The final positioning is when the port is stopped, the mbuf of the pkt_first_seg pointer is not released. Resources leak. The patch scheme is to judge whether the pointer is empty when the port is stopped, and release the corresponding mbuf if it is not empty.
