From f6e53bb96587d7fdfe8bfb345dd45ef20538c04d Mon Sep 17 00:00:00 2001 From: Coco Li Date: Fri, 28 Jan 2022 20:36:36 +0800 Subject: [PATCH] selftests: Calculate udpgso segment count without header adjustment stable inclusion from stable-v5.10.90 commit 13c1bf43b6744fcf28387cdec6f5b5c24a32f20a bugzilla: 186168 https://gitee.com/openeuler/kernel/issues/I4SHY1 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=13c1bf43b6744fcf28387cdec6f5b5c24a32f20a -------------------------------- [ Upstream commit 5471d5226c3b39b3d2f7011c082d5715795bd65c ] The below referenced commit correctly updated the computation of number of segments (gso_size) by using only the gso payload size and removing the header lengths. With this change the regression test started failing. Update the tests to match this new behavior. Both IPv4 and IPv6 tests are updated, as a separate patch in this series will update udp_v6_send_skb to match this change in udp_send_skb.
