From 374bc35e4156b8caf7f51057618db47c094e2f05 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Tue, 22 Sep 2020 10:14:39 +0800 Subject: [PATCH] xfrm: Always set XFRM_TRANSFORMED in xfrm{4, 6}_output_finish stable inclusion from linux-4.19.119 commit 995908dc5b51bfb42edf69160b0dd062d97ee07e -------------------------------- [ Upstream commit 0c922a4850eba2e668f73a3f1153196e09abb251 ] IPSKB_XFRM_TRANSFORMED and IP6SKB_XFRM_TRANSFORMED are skb flags set by xfrm code to tell other skb handlers that the packet has been passed through the xfrm output functions. Simplify the code and just always set them rather than conditionally based on netfilter enabled thus making the flag available for other users. Signed-off-by: David Ahern Signed-off-by: David S.
