From ec3bb890817e4398f2d46e12e2e205495b116be9 Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Mon, 22 Nov 2021 11:33:13 +0100 Subject: [PATCH] xfrm: fix dflt policy check when there is no policy configured When there is no policy configured on the system, the default policy is checked in xfrm_route_forward. However, it was done with the wrong direction (XFRM_POLICY_FWD instead of XFRM_POLICY_OUT). The default policy for XFRM_POLICY_FWD was checked just before, with a call to xfrm[46]_policy_check().
