docker/0004-bsc1073877-apparmor-clobber-docker-default-profile-o.patch
Aleksa Sarai cb6967cb97 - Update to Docker 20.10.3-ce. See upstream changelog in the packaged
/usr/share/doc/packages/docker/CHANGELOG.md. CVE-2021-21285 CVE-2021-21284
- Drop docker-runc, docker-test and docker-libnetwork packages. We now just use
  the upstream runc package (it's stable enough and Docker no longer pins git
  versions). docker-libnetwork is so unstable that it doesn't have any
  versioning scheme and so it really doesn't make sense to maintain the project
  as a separate package. bsc#1181641 bsc#1181677

Subject: [PATCH 4/4] bsc1073877: apparmor: clobber docker-default profile on
start
In the process of making docker-default reloading far less expensive,
567ef8e7858c ("daemon: switch to 'ensure' workflow for AppArmor
profiles") mistakenly made the initial profile load at dockerd start-up
lazy. As a result, if you have a running Docker daemon and upgrade it to
a new one with an updated AppArmor profile the new profile will not take
effect (because the old one is still loaded). The fix for this is quite
trivial, and just requires us to clobber the profile on start-up.
Fixes: 567ef8e7858c ("daemon: switch to 'ensure' workflow for AppArmor profiles")
