As this attribute cannot be enlarged, we need to use some form of translation of 64-bit quirk bits. This problem was discussed on USB list https://lore.kernel.org/linux-usb/f9e8acb5-32d5-4a30-859f-d4336a86b31a@gmail.com/ The initial solution to use static array extensively increased the size of the kernel module, so I decided to try the second suggested solution: generate a table by host-compiled program and use bit 31 to indicate that the value is index and not actual value. This patch adds a host-compiled program that processes unusual_devs.h (and unusual_uas.h) and generates files unusual-flags.c and unusual-flags-uas.c (for pre-processed USB device table with 32 bit device info) and unusual-flags.h with function to translate flags to 64-bits from device-info. The separate generated header file is needed as storage and UAS drivers headers are tightly bound together and any ohter solution seems to be more pervasive. Translation function is used only in usb-storage and uas modules; all other USB storage modules store flags directly, using only 32-bit integers. This translation is unnecessary for a 64-bit system, but I keep it in place for simplicity. (Also, I did not find a reliable way a host-compiled program can detect that the target platform has 32-bit unsigned long (usual macros do not work here!).

All common USB/SATA or USB/NVMe adapters I tested need this patch. USB mass storage devices that do not support SECURITY IN/OUT SCSI commands can support ATA12 pass-thru command. Internal kernel implementation for OPAL interface currently supports only SCSI SECURITY IN/OUT wrapper. USB mass storage also turns off SCSI command enumeration, so SECURITY IN/OUT in the SCSI layer will be disabled. Note: sedutils and some other OPAL tools already use ATA-12 pass-thru. This patch - enables SCSI security flag for USB mass storage and UAS device by default. - adds an optional wrapper to the SCSI layer for the ATA-12 pass-thru command as an alternative if SECURITY IN/OUT is unavailable. In short, the patch runs these steps: 1) USB drives (mass-storage, UAS) enables security driver flag by default if not disabled by quirk 2) SCSI device enumerates SECURITY IN/OUT support. If detected, SECURITY ON/OUT wrapper is used (as in the current code). If not, new ATA12 pass-thru wrapper is used instead. 3) SED OPAL code tries OPAL discovery command for device. If it receives correct reply, OPAL is enabled for the device. With the changes above, the TCG OPAL support works with USB adapters that support the ATA-12 command. As kernel OPAL code runs discover commands on initialization, on devices that do not support pass-through, OPAL remains disabled. The patch also adds a quirk flag to disable security commands for particular devices if firmware is buggy.

The only way to recover is PSID reset and physical reconnection of the device. This looks like a wrong implementation of OPAL standard (and I will try to report it to Realtek as it happens for all firmware versions I have), but for now, these adapters are unusable for OPAL.
