This patch series implement a small set of the Opal protocol for self encrypting devices. It's implemented only what is needed for saving a password and unlocking a given "locking range". The password is saved on the driver and replayed back to the device on resume from suspend to RAM. It is specifically supporting the single user mode. It is not planned to implement the full Opal protocol (at least not for now). Rafael Antognolli (2): Add optane OPAL unlocking code. NVMe: Add ioctls to save and unlock an Opal locking range. drivers/nvme/host/Kconfig | 7 + drivers/nvme/host/Makefile | 1 + drivers/nvme/host/core.c | 9 + drivers/nvme/host/opal.c | 1270 +++++++++++++++++++++++++++++++++++++ drivers/nvme/host/opal.h | 73 +++ drivers/nvme/host/opal_internal.h | 501 +++++++++++++++ include/uapi/linux/nvme_ioctl.h | 7 + 7 files changed, 1868 insertions(+) create mode 100644 drivers/nvme/host/opal.c create mode 100644 drivers/nvme/host/opal.h create mode 100644 drivers/nvme/host/opal_internal.h -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
