[PATCH 8/8] apparmor: let qemu load old shared objects after upgrades

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since [1] qemu can after upgrade fall back to pre-upgrade modules
to still be able to dynamically load qmeu-module based features.

The paths for these modules are pre-defined by the code and should
be allowed to be mapped and loaded from which will allow packagers
avoiding the inability of late feature load [2] after package upgrades.
