cryptsetup2 toolstack version bump and script fixes to support multi-LUKS containers (BTRFS QubesOS 4.2)
cryptsetup2 2.6.1 is a new release that supports reencryption of Q4.2 release LUKS2 volumes created at installation.
This is a critical feature for the Qubes OS 4.2 release for added data at rest protection
Cryptsetup 2.6.x internal changes:
- Argon2 used externally and internally: requires a lot of RAM and CPU to derivate passphrase to key validated in key slots.
- This is used to rate limit efficiently bruteforcing of LUKS key slots, requiring each offline brute force attempt to consume ~15-30 seconds per attempt
- OF course, strong passphrases are still recommended, but bruteforcing LUKSv2 containers with Argon2 would require immense time, ram and CPU even to bruteforce low entropy passphrase/PINs.
- passphrase change doesn't permit LUKS key slot specification anymore: key slot rotates (new one consusumed per op: then old one wiped internally. EG: LUKS key slot 1 created, then 0 deleted)
- reencryption doesn't permit old call arguments. No more direct-io; inadmissively slow through AIO (async) calls, need workarounds for good enough perfs (arguments + newer kernel with cloudfare fixes in tree)
cryptsetup 2.6.1 requires:
- lvm2 2.03.23, which is also included in this PR.
- requires libaio, which is also included in this PR (could be hacked out but deep dependency at first sight: left in)
- requires util-linux 2.39
- patches for reproducible builds are included for above 3 packages.
luks-functions was updated to support the new cryptsetup2 version calls/changes
- reencryption happen in direct-io, offline mode and without locking, requiring linux 5.10.9+ to bypass linux queues
- from tests, this is best for performance and reliability in single-user mode
- LUKS container ops now validate Disk Recovery Key (DRK) passphrase prior and DRK key slot prior of going forward if needed, failing early.
- Heads don't expect DRK to be in static key slot anymore, and finds the DRK key slot dynamically.
- If reencrytipn/passphrase change: make sure all LUKS containers on same block device can be unlocked with same DRK
- Reencryption: requires to know which key slot to reencrypt.
- Find LUKS key slot that unlocks with DRK passphrase unlock prior of reencrypt call
- Passphrase change: no slot can be passed, but key slot of DRK rotates.
kexec-seal-key
- TPM LUKS Disk Unlock Key key slots have changed to be set in max slots per LUKS version (LUKSv1:7 /LUKSv2: 31)
- If key slot != default LUKS version's keyslot outside of DRK key slot: prompt the user before wiping that key slot, otherwise wipe automatically
- This takes for granted that the DRK key slot alone is needed on the system and Heads controls the LUKS key slots.
- If user has something else going on, ie: Using USB Security dongle + TPM DUK, then the user will need to say no when wiping keys.
- It was suggested to leave LUKS key slots outside of DRK alone, but then: what to do when all key slots would be used?
- Alternative implementation could be to only prompt users to wipe keyslots other then DRK when key slots are all used (LUKSv1: 0-7, LUKSv2: 0-31)
- But then cleanup would need to happen prior of operations (LUKS passphrase change, TPM DUK setup) and could be problematic.
- LUKS containers now checked to be same LUKS version prior of permitting to set TPM DUK and will refuse to go forward of different versions.
TODO:
- async (AIO) calls are not used. direct-io is used instead. libaio could be hacked out
- this could be subject to future work
Notes:
- time to deprecated legacy boards the do not enough space for the new space requirements
- x230-legacy, x230-legacy-flash, x230-hotp-legacy
- t430-legacy, t430-legacy-flash, t430-hotp-legacy already deprecated
Unrelated:
- typos fixes found along the way
