Subject: [PATCH 4/5] 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")
