Bug description:
SRU Justification
[Impact]
The kvm flavours currently do not enable dm-verity. This stops us from
using integrity protected and verified images in VMs using this kernel
flavour.
[Fix]
Please consider enabling the following kconfigs:
CONFIG_DM_VERITY
CONFIG_DM_VERITY_VERIFY_ROOTHASH_SIG
CONFIG_DM_VERITY_VERIFY_ROOTHASH_SIG_SECONDARY_KEYRING
CONFIG_IMA_ARCH_POLICY
(The latter is needed to ensure that MoK keys can be used to verify
dm-verity images too, via the machine keyring linked to the secondary
keyring)
These are already enabled in the 'main' kernel config, and in other
distros.
As a specific and explicit use case, in the systemd project we want to
test functionality provided by systemd that needs these kconfigs on
Ubuntu machines running the kvm flavour kernel.
[Regression Potential]
MOK keys may not be correctly read.
