File bsc1073877-0001-apparmor-allow-receiving-of-signals-from-docker-kill.patch of Package docker.8059
From 2cc9da975798847cd0a37d1571d8a0f1d72b522d Mon Sep 17 00:00:00 2001 From: Aleksa Sarai <asarai@suse.de> 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.
