Thank you for bringing IMA support to device mapper. The addition of dm-verity to IMA is very useful for the project I'm working on where we boot our distribution from removable USB media. One of our goals is to detect tampering of the root file system remotely. Therefore we enabled dm-verity support but implementing remote attestation for dm-verity from userland is not ideal which was our initial plan. This patch set enables us to leverage to already implemented IMA attestation infrastructure by the remote attestation service that we are using (Keylime) without trying to roll a custom solution. We tested the initial RFC patch set and will continue testing with this one to see if it fully works in our environment and with our use case. Thore Sommer
