After ufshcd_wl_shutdown() set device power off and link off, ufshcd_shutdown() could turn off clock/power. Also remove pm_runtime_get_sync. The reason why it is safe to remove pm_runtime_get_sync() is because: - ufshcd_wl_shutdown() -> pm_runtime_get_sync() will resume hba->dev too. - device resume(turn on clk/power) is not required, even if device is in RPM_SUSPENDED.

Measurements for one particular UFS controller + UFS device show a 25% higher read bandwidth if the maximum data buffer size is increased from 512 KiB to 1 MiB. Hence increase the maximum size of the data buffer associated with a single request from SCSI_DEFAULT_MAX_SECTORS (1024) * 512 bytes = 512 KiB to 1 MiB. Notes: - The maximum data buffer size supported by the UFSHCI specification is 65535 * 256 KiB or about 16 GiB. - The maximum data buffer size for READ(10) commands is 65535 logical blocks. To transfer more than 65535 * 4096 bytes = 255 MiB with a single SCSI command, the READ(16) command is required. Support for READ(16) is optional in the UFS 3.1 and UFS 4.0 standards.

This patch removes XDWRITEREAD support because it never fully worked when it was added in the initial LIO merge and it's been fully broken since 2013 from commit a2890087 ("target: Add compare_and_write_post() completion callback fall through"). The two issues above are: 1. XDWRITEREAD support was just never completed when LIO was merged. We never did the DISABLE WRITE check and so we never write data out. 2. Since the commit above, we never complete the command. After we do the XOR, we return from xdreadwrite_callback and that's it. We never send a response for the command, so the command will always time out and fail. Since this has been fully broken for almost nine years this patch just removes emulated support.

RFC7143 states that Initiator decides what type of authentication to use: The initiator MUST continue with: CHAP_N=<N> CHAP_R=<R> or, if it requires target authentication, with: CHAP_N=<N> CHAP_R=<R> CHAP_I=<I> CHAP_C=<C> Allow one way authentication if mutual authentication is configured.

Variable length SCSI commands are transferred over iSCSI via two CDB buffers - in Basic Header Segment and in Additional Header Segment (AHS). Since AHS is not supported yet, a target reads just BHS (48 byte) from TCP and treats the remaining octets as a next new iSCSI PDU that causes protocol errors.

UFS storage devices require bRefClkFreq attribute to be set to operate correctly at high speed mode. The necessary value is determined by what the SoC / board supports. The standard doesn't specify a method to query the value, so the information needs to be fed in separately. DT information feeds into setting up the clock framework, so platforms using DT can get the UFS reference clock frequency from the clock framework. A special node "ref_clk" from the clock array for the UFS controller node is used as the source for the information. On the platforms that do not use DT (e.g. Intel), the alternative mechanism to feed the intended reference clock frequency is necessary. Specifying the necessary information in DSD of the UFS controller ACPI node is an alternative mechanism proposed in this patch. Those can be accessed via firmware property facility in the kernel and in many ways simillar to querying properties defined in DT. This patch introduces a small helper function to query a predetermined ACPI supplied property of the UFS controller, and uses it to attempt retrieving reference clock value, unless that was already done by the clock infrastructure.

Update driver to track cumulative pending large data size at the controller level and at the throttle group level. When one of the values meet or exceed the controller's firmware-determined high threshold value, then the driver will divert future selective I/O to the firmware. Once both controller level and at the throttle group level cumulative pending large data size reach controller's firmware determined low threshold value, then the driver will stop diverting I/Os to the firmware.

When a SCSI device is removed while in active use, currently sg will immediately return -ENODEV on any attempt to wait for active commands that were sent before the removal. This is problematic for commands that use SG_FLAG_DIRECT_IO since the data buffer may still be in use by the kernel when userspace frees or reuses it after getting ENODEV, leading to corrupted userspace memory (in the case of READ-type commands) or corrupted data being sent to the device (in the case of WRITE-type commands). This has been seen in practice when logging out of a iscsi_tcp session, where the iSCSI driver may still be processing commands after the device has been marked for removal. Change the policy to allow userspace to wait for active sg commands even when the device is being removed. Return -ENODEV only when there are no more responses to read.

On some platforms, the current logic of relying on finding new packet solely based on signature pattern can lead to driver reading stale packets. Though this is a bug in those platforms, reduce such exposures by limiting reading packets until the IN pointer. Two module parameters are introduced: ql2xrspq_follow_inptr: When set, on newer adapters that has queue pointer shadowing, look for response packets only until response queue in pointer. When reset, response packets are read based on a signature pattern logic (old way). ql2xrspq_follow_inptr_legacy: Like ql2xrspq_follow_inptr, but for those adapters where there is no queue pointer shadowing.

Allow user to override the default driver timeout for controller ready. There are some rare configurations which require the driver to wait longer than the normal 3 minutes for the controller to complete its bootup sequence and be ready to accept commands from the driver. The module parameter is: ctrl_ready_timeout= { 0 | 30-1800 } and specifies the timeout in seconds for the driver to wait for controller ready. The valid range is 0 or 30-1800. The default value is 0, which causes the driver to use a timeout of 180 seconds (3 minutes).
