block/sed-opal: allocate struct opal_dev dynamically Insted of bloating the containing structure with it all the time this allocates struct opal_dev dynamically. Additionally this allows moving the definition of struct opal_dev into sed-opal.c. For this a new private data field is added to it that is passed to the send/receive callback.

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.

block: sed-opal: pass steps via argument rather than via opal_dev The steps argument is only read by the next function, so it can be passed directly as an argument rather than via opal_dev. Normally, the steps is an array on the stack, so the pointer stops being valid then the function that set opal_dev.steps returns. If opal_dev.steps was not set to NULL before return it would become a dangling pointer. When the steps are passed as argument this becomes easier to see and more difficult to misuse.

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.

block: sed-opal: Add support to read/write opal tables generically This feature gives the user RW access to any opal table with admin1 authority. The flags described in the new structure determines if the user wants to read/write the data. Flags are checked for valid values in order to allow future features to be added to the ioctl. The user can provide the desired table's UID. Also, the ioctl provides a size and offset field and internally will loop data accesses to return the full data block. Read overrun is prevented by the initiator's sec_send_recv() backend. The ioctl provides a private field with the intention to accommodate any future expansions to the ioctl.

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.

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.

block: sed-opal: PSID reverttper capability PSID is a 32 character password printed on the drive label, to prove its physical access. This PSID reverttper function is very useful to regain the control over the drive when it is locked and the user can no longer access it because of some failures. However, *all the data on the drive is completely erased*. This method is advisable only when the user is exhausted of all other recovery methods. PSID capabilities are described in: https://trustedcomputinggroup.org/wp-content/uploads/TCG_Storage-Opal_Feature_Set_PSID_v1.00_r1.00.pdf Signed-off-by: Revanth Rajashekar <revanth.rajashekar@intel.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>

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.

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.

Normally, the steps is an array on the stack, so the pointer stops being valid then the function that set opal_dev.steps returns.

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.

block: sed-opal: Add support to read/write opal tables generically This feature gives the user RW access to any opal table with admin1 authority. The flags described in the new structure determines if the user wants to read/write the data. Flags are checked for valid values in order to allow future features to be added to the ioctl. The user can provide the desired table's UID. Also, the ioctl provides a size and offset field and internally will loop data accesses to return the full data block. Read overrun is prevented by the initiator's sec_send_recv() backend. The ioctl provides a private field with the intention to accommodate any future expansions to the ioctl.

block/sed-opal: allocate struct opal_dev dynamically Insted of bloating the containing structure with it all the time this allocates struct opal_dev dynamically. Additionally this allows moving the definition of struct opal_dev into sed-opal.c. For this a new private data field is added to it that is passed to the send/receive callback. After that a lot of internals can be made private as well.

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.
