From 9e48fb3d80a91074ba3f7e0219edde53ec03ef92 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 4 May 2018 09:40:03 +0200 Subject: [PATCH] seccomp: Use PR_SPEC_FORCE_DISABLE commit b849a812f7eb92e96d1c8239b06581b2cfd8b275 upstream. Use PR_SPEC_FORCE_DISABLE in seccomp() because seccomp does not allow to widen restrictions.
