block: Fix regression in sed-opal for a saved key. The commit 3bfeb61256643281ac4be5b8a57e9d9da3db4335 introduced the use of keyring for sed-opal. Unfortunately, there is also a possibility to save the Opal key used in opal_lock_unlock(). This patch switches the order of operation, so the cached key is used instead of failure for opal_get_key. The problem was found by the cryptsetup Opal test recently added to the cryptsetup tree.

sed-opal: allow using IOC_OPAL_SAVE for locking too Usually when closing a crypto device (eg: dm-crypt with LUKS) the volume key is not required, as it requires root privileges anyway, and root can deny access to a disk in many ways regardless. Requiring the volume key to lock the device is a peculiarity of the OPAL specification. Given we might already have saved the key if the user requested it via the 'IOC_OPAL_SAVE' ioctl, we can use that key to lock the device if no key was provided here and the locking range matches, and the user sets the appropriate flag with 'IOC_OPAL_SAVE'. This allows integrating OPAL with tools and libraries that are used to the common behaviour and do not ask for the volume key when closing a device. Callers can always pass a non-zero key and it will be used regardless, as before.

block: sed-opal: kmalloc the cmd/resp buffers In accordance with [1] the DMA-able memory buffers must be cacheline-aligned otherwise the cache writing-back and invalidation performed during the mapping may cause the adjacent data being lost. It's specifically required for the DMA-noncoherent platforms [2]. Seeing the opal_dev.{cmd,resp} buffers are implicitly used for DMAs in the NVME and SCSI/SD drivers in framework of the nvme_sec_submit() and sd_sec_submit() methods respectively they must be cacheline-aligned to prevent the denoted problem. One of the option to guarantee that is to kmalloc the buffers [2]. Let's explicitly allocate them then instead of embedding into the opal_dev structure instance. Note this fix was inspired by the commit c94b7f9bab22 ("nvme-hwmon: kmalloc the NVME SMART log buffer").

See "struct opal_status" and OPAL_FL_* bits for the status information currently returned. This is necessary to be able to check whether a device is OPAL enabled, set up, locked or unlocked from userspace programs like systemd-cryptsetup and libcryptsetup.

block: sed-opal: add ioctl for done-mark of shadow mbr Enable users to mark the shadow mbr as done without completely deactivating the shadow mbr feature. This may be useful on reboots, when the power to the disk is not disconnected in between and the shadow mbr stores the required boot files. Of course, this saves also the (few) commands required to enable the feature if it is already enabled and one only wants to mark the shadow mbr as done.

block: sed-opal: fix IOC_OPAL_ENABLE_DISABLE_MBR The implementation of IOC_OPAL_ENABLE_DISABLE_MBR handled the value opal_mbr_data.enable_disable incorrectly: enable_disable is expected to be one of OPAL_MBR_ENABLE(0) or OPAL_MBR_DISABLE(1). enable_disable was passed directly to set_mbr_done and set_mbr_enable_disable where is was interpreted as either OPAL_TRUE(1) or OPAL_FALSE(0). The end result was that calling IOC_OPAL_ENABLE_DISABLE_MBR with OPAL_MBR_ENABLE actually disabled the shadow MBR and vice versa. This patch adds correct conversion from OPAL_MBR_DISABLE/ENABLE to OPAL_FALSE/TRUE. The change affects existing programs using IOC_OPAL_ENABLE_DISABLE_MBR but this is typically used only once when setting up an Opal drive.

block: sed-opal: Set MBRDone on S3 resume path if TPER is MBREnabled Users who are booting off their Opal enabled drives are having issues when they have a shadow MBR set up after s3/resume cycle. When the Drive has a shadow MBR setup the MBRDone flag is set to false upon power loss (S3/S4/S5). When the MBRDone flag is false I/O to LBA 0 -> LBA_END_MBR are remapped to the shadow mbr of the drive. If the drive contains useful data in the 0 -> end_mbr range upon s3 resume the user can never get to that data as the drive will keep remapping it to the MBR. To fix this when we unlock on S3 resume, we need to tell the drive that we're done with the shadow mbr (even though we didnt use it) by setting true to MBRDone. This way the drive will stop the remapping and the user can access their data.
