nvme: rework NVME_AUTH Kconfig selection

2023-10-12T15:04:49+00:00

Having a single Kconfig symbol NVME_AUTH conflates the selection
of the authentication functions from nvme/common and nvme/host,
causing kbuild robot to complain when building the nvme target
only. So introduce a Kconfig symbol NVME_HOST_AUTH for the nvme
host bits and use NVME_AUTH for the common functions only.
And move the CRYPTO selection into nvme/common to make it
easier to read.

Pull SCSI updates from James Bottomley:
 "Updates to the usual drivers (ufs, pm80xx, libata-scsi, smartpqi,
  lpfc, qla2xxx).

  We have a couple of major core changes impacting other systems:

   - Command Duration Limits, which spills into block and ATA

   - block level Persistent Reservation Operations, which touches block,
     nvme, target and dm

  Both of these are added with merge commits containing a cover letter
  explaining what's going on"

nvme: move sysfs code to a dedicated sysfs.c file

2023-06-12T17:36:59+00:00

The core.c file became long and hard to maintain. Create a dedicated
file to centralize the sysfs functionality. This is a common practice to
separate sysfs/configfs related logic from the main driver logic .c file.
For example, in the nvmet module the configfs interface has its own
dedicated file.

This patch does not include any functional changes.

nvme: implement In-Band authentication

2022-08-02T23:14:49+00:00

Implement NVMe-oF In-Band authentication according to NVMe TPAR 8006.
This patch adds two new fabric options 'dhchap_secret' to specify the
pre-shared key (in ASCII respresentation according to NVMe 2.0 section
8.13.5.8 'Secret representation') and 'dhchap_ctrl_secret' to specify
the pre-shared controller key for bi-directional authentication of both
the host and the controller.
Re-authentication can be triggered by writing the PSK into the new
controller sysfs attribute 'dhchap_secret' or 'dhchap_ctrl_secret'.

nvme-apple: Add initial Apple SoC NVMe driver

2022-05-02T15:24:45+00:00

Apple SoCs such as the M1 come with an embedded NVMe controller that
is not attached to any PCIe bus. Additionally, it doesn't conform
to the NVMe specification and requires a bunch of changes to command
submission and IOMMU configuration to work.

remove the lightnvm subsystem

2021-08-14T21:54:09+00:00

Lightnvm supports the OCSSD 1.x and 2.0 specs which were early attempts
to produce Open Channel SSDs and never made it into the NVMe spec
proper.  They have since been superceeded by NVMe enhancements such
as ZNS support.  Remove the support per the deprecation schedule.
