linux-*: please enable dm-verity kconfigs to allow MoK/db verified root images

[Luca Boccassi]

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_INTEGRITY_MACHINE_KEYRING
CONFIG_IMA_ARCH_POLICY (this might not be necessary if the machine keyring implementation is patched to skip the check enabled by this kconfig)

(The latter two are 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.

To verify whether this works, add a certificate to MOK, boot and check the content of the secondary keyring. The machine keyring should show up under it, and it should show the certificates loaded in MOK. E.g.:

$ sudo keyctl show %:.secondary_trusted_keys
Keyring
 159454604 ---lswrv 0 0 keyring: .secondary_trusted_keys
  88754641 ---lswrv 0 0 \_ keyring: .builtin_trusted_keys
 889010778 ---lswrv 0 0 | \_ asymmetric: Debian Secure Boot CA: 6ccece7e4c6c0d1f6149f3dd27dfcc5cbb419ea1
 799434660 ---lswrv 0 0 | \_ asymmetric: Debian Secure Boot Signer 2022 - linux: 14011249c2675ea8e5148542202005810584b25f
 541326986 ---lswrv 0 0 \_ keyring: .machine
 188508854 ---lswrv 0 0 \_ asymmetric: Debian Secure Boot CA: 6ccece7e4c6c0d1f6149f3dd27dfcc5cbb419ea1
 475039424 ---lswrv 0 0 \_ asymmetric: sb-bluca: Secure Boot Signing: 9a61c52d07d78a76935e67bdbe3f5e6968d62479

[Regression Potential]

MOK keys may not be correctly read.

[Luca Boccassi (bluca)]

Also, please enable CONFIG_DM_VERITY_VERIFY_ROOTHASH_SIG_SECONDARY_KEYRING on the cloud kernels - especially I am interested in the Azure one. Same reason as above - the other options are already enabled there.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 2019040

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Luca Boccassi (bluca)]

There's no specific log to share, I've downloaded the kconfig for the kvm flavour from the linux-buildinfo-6.2.0-1003-kvm_6.2.0-1003.3_amd64.deb package, extracted usr/lib/linux/6.2.0-1003-kvm/config and checked for these kconfigs, and they are not present:

$ grep DM_VERITY config
# CONFIG_DM_VERITY is not set
$ grep IMA_ARCH config
$

[Tim Gardner (timg-tpi)]

Submitted patches for review: https://lists.ubuntu.com/archives/kernel-team/2023-May/139435.html

Note that the proposed patches do not include IMA_ARCH given the performance impacts that option imposes.

[Luca Boccassi (bluca)]

Thank you!

Do you have details about the performance impact of IMA_ARCH?

[Luca Boccassi (bluca)]

Hi, any update on these configs changes? Have they been queued?

@all
First I checked with Luca and understood that he considers it generally good to enable those options, but his immediate need atm is on azure.

@Luca
I talked to a friend (thanks Gauthier) in regard to have a look at these options in the current azure kernel. At least there, on current lunar, the options seem to be already in place:

ubuntu@lunar:~$ uname -r
6.2.0-1008-azure
ubuntu@lunar:~$ grep -i dm_verity /boot/config-6.2.0-1008-azure
CONFIG_DM_VERITY=m

CONFIG_DM_VERITY_VERIFY_ROOTHASH_SIG_SECONDARY_KEYRING=y
# CONFIG_DM_VERITY_FEC is not set
