From 3464bd58d266b0640774952e825558044ffc64e2 Mon Sep 17 00:00:00 2001 From: Aleksa Sarai Date: Sun, 8 Apr 2018 20:21:30 +1000 Subject: [PATCH 1/2] apparmor: allow receiving of signals from 'docker kill' In newer kernels, AppArmor will reject attempts to send signals to a container because the signal originated from outside of that AppArmor profile. Correct this by allowing all unconfined signals to be received.
