From 80f5974d15ea96c7112604c7999a83a502d15b9f Mon Sep 17 00:00:00 2001 From: Daniel Axtens Date: Thu, 1 Mar 2018 17:13:39 +1100 Subject: [PATCH] net: xfrm: use skb_gso_validate_network_len() to check gso sizes Replace skb_gso_network_seglen() with skb_gso_validate_network_len(), as it considers the GSO_BY_FRAGS case.
