Bug#882697: stretch-pu: package apparmor/2.11.0-3+deb9u1
Package: release.debian.org
Severity: normal
Tags: stretch
User: release.debian.org@packages.debian.org
Usertags: pu
Hi!
this update avoids breakage for Stretch users who have enabled AppArmor and run
Linux 4.14+ (e.g. from backports once it's there), by pinning the AppArmor
feature set in the kernel to the Stretch kernel's feature set, i.e. the feature
set the AppArmor policy shipped in Stretch supports (it's not ready to deal with
new AppArmor mediation features brought in recent kernels).
We already have exactly the same thing in current testing/sid, albeit with Linux
4.13's feature set for now.
Cheers!
