- lib.rs: replace HostCert's derived Debug with a hand-written impl that
redacts private_key/private_key_v2 (mirrors AacsAuth/Unlocked); keep Clone
derived. Add a HostCert case to the Debug leak-guard tests.
- aacs/mod.rs: warn when the cert handshake drops a read_data_key (bus key)
because the drive refused the fetch (read_data_key None + err Some) so the
otherwise-invisible UHD bus-key failure is diagnosable. Public Unlocked
type and return contract unchanged.
- mt1959: add byte-for-byte CDB assertions for variant_a's WRITE_BUFFER and
0x45 verify read, and variant_b's Step-2 metadata read and Step-3
write-extra CDBs.
- renesas: add a test where the A read fails, the knock runs, and the B read
succeeds, asserting the knock CDB is issued between A and B.
- vid.rs: add a test for the Err-with-sense branch classifying as Ok(None)
VID-miss, not Err(Transport).
- docs/freemkv-abi.md: correct the stale claim that a VID miss fails the
unlock; full_unlock now returns Ok(Unlocked{vid:None}) on a VID miss.
freemkv-unlock
The unlock layer for the freemkv toolchain.
An unlocker removes a drive-level bus-encryption barrier so the drive serves readable (de-bus'd / de-scrambled) sectors. Content-key decryption is a separate concern — the consumer's job.
This crate defines the Unlocker contract and a generic SCSI transport
contract, and holds the self-contained unlocker modules. The consumer
(libfreemkv) depends on this crate and
dispatches through all_unlockers(); it never names an individual unlocker, and
clients of libfreemkv are oblivious to unlockers entirely (as they are to the
SCSI layer).
use freemkv_unlock::UnlockError;
// Drive-prep: try each unlocker's feature unlock until one claims the drive.
// `NotApplicable` means "not this unlocker's drive" — move on; a transport
// error means a dead bus — abort. `unlock_bus` follows the same contract for
// removing per-disc bus encryption.
for u in freemkv_unlock::all_unlockers() {
match u.unlock_features(&mut scsi, &ctx) {
Ok(unlocked) => return Ok(unlocked),
Err(UnlockError::NotApplicable) => continue,
Err(e) => return Err(e),
}
}
To remove an unlocker, delete its module directory and its one line in
all_unlockers() — nothing else changes.
