bb2e331468 scsi: virtio-scsi: Correctly handle the case where all LUNs are unplugged
Commit 5ff8437214 ("scsi: virtio_scsi: unplug LUNs when events missed")
missed a corner case in which all the LUNs are unplugged at the same time.

In this case INQUIRY returns DID_BAD_TARGET. Detect this and unplug the
LUN.

fc13638ae9 scsi: scsi_debug: Implement tur_ms_to_ready parameter
The current driver responds to TEST UNIT READY (TUR) with a GOOD status
immediately after a scsi_debug device (LU) is created. This is unrealistic
as even SSDs take some time after power-on before accepting media access
commands.

Add the tur_ms_to_ready parameter whose unit is milliseconds (default 0)
and is the period before which a TUR (or any media access command) will set
the CHECK CONDITION status with a sense key of NOT READY and an additional
sense of "Logical unit is in process of becoming ready".  The period starts
when each scsi_debug device is created.

This patch was prompted by T10 proposal 20-061r2 which was accepted on
2020716. It adds that a TUR in the situation described in the previous
paragraph may set the INFO field (or descriptor) in the sense data to the
estimated number in milliseconds before a subsequent TUR will yield a GOOD
status. This patch follows that advice.

84905d34f1 scsi: scsi_debug: Fix request sense
The SCSI REQUEST SENSE command emulation was found to be broken.  It is a
quite complex command so try and make it do a subset of what it should
do. Remove the attempt to mimic SCSI-1 REQUEST SENSE (i.e. return the sense
data for the previous failed command). Add some reporting of "pollable"
sense data [see spc6r02: 5.12.2]. Keep the IEC mode page MRIE=6 TEST=1
predictive failure reporting.

0255b1e3d8 scsi: ufs-mediatek: Prevent LPM operation on undeclared VCC
In some platforms, VCC regulator may not be declared in device tree to keep
itself "always-on". In this case, hba->vreg_info.vcc is NULL and shall not
be operated during any flow.

Prevent possible NULL hba->vreg_info.vcc access in LPM mode by checking
if it is valid first.

a57066b1a0 Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
The UDP reuseport conflict was a little bit tricky.

The net-next code, via bpf-next, extracted the reuseport handling
into a helper so that the BPF sk lookup code could invoke it.

At the same time, the logic for reuseport handling of unconnected
sockets changed via commit efc6b6f6c3
which changed the logic to carry on the reuseport result into the
rest of the lookup loop if we do not return immediately.

This requires moving the reuseport_has_conns() logic into the callers.

While we are here, get rid of inline directives as they do not belong
in foo.c files.

The other changes were cases of more straightforward overlapping
modifications.

In theory, a panic can happen after a bus or host reset with dma_started
flag set. Fix this by halting the DMA before reinitializing the host.
Don't assume that ms->current_req is set when halt_dma() is invoked as it
may not hold for bus or host reset.

BTW, this particular Conner drive can be made to work by inhibiting
disconnect/reselect with 'mesh.resel_targets=0'.

3865337965 scsi: libsas: Check link status in ATA prereset()
libata currently attempts to reset even if the SATA disk is unplugged.  To
avoid the meaningless reset of a missing disk, libsas should report offline
status to libata. libata already provides a .prereset callback for this
purpose. This is called by ata_eh_reset() and can be used to influence
whether a reset attempt should be made.

Add sas_ata_preset callback to check status of phy and disk. If the disk is
already offline or phy is disabled, we return -ENOENT to libata to avoid
the reset.

8f38f8e0a3 scsi: block: pm: Simplify resume handling
Commit 05d18ae1cc ("scsi: pm: Balance pm_only counter of request queue
during system resume") fixed a problem in the block layer's runtime-PM
code: blk_set_runtime_active() failed to call blk_clear_pm_only().
However, the commit's implementation was awkward; it forced the SCSI
system-resume handler to choose whether to call blk_post_runtime_resume()
or blk_set_runtime_active(), depending on whether or not the SCSI device
had previously been runtime suspended.

This patch simplifies the situation considerably by adding the missing
function call directly into blk_set_runtime_active() (under the condition
that the queue is not already in the RPM_ACTIVE state).  This allows the
SCSI routine to revert back to its original form.  Furthermore, making this
change reveals that blk_post_runtime_resume() (in its success pathway) does
exactly the same thing as blk_set_runtime_active().  The duplicate code is
easily removed by making one routine call the other.

No functional changes are intended.

df4ec2fa7a scsi: ufs-qcom: Add Inline Crypto Engine support
Add support for Qualcomm Inline Crypto Engine (ICE) to ufs-qcom.

The standards-compliant parts, such as querying the crypto capabilities and
enabling crypto for individual UFS requests, are already handled by
ufshcd-crypto.c, which itself is wired into the blk-crypto framework.
However, ICE requires vendor-specific init, enable, and resume logic, and
it requires that keys be programmed and evicted by vendor-specific SMC
calls.  Make the ufs-qcom driver handle these details.

I tested this on Dragonboard 845c, which is a publicly available
development board that uses the Snapdragon 845 SoC and runs the upstream
Linux kernel.  This is the same SoC used in the Pixel 3 and Pixel 3 XL
phones.  This testing included (among other things) verifying that the
expected ciphertext was produced, both manually using ext4 encryption and
automatically using a block layer self-test I've written.

I've also tested that this driver works nearly as-is on the Snapdragon 765
and Snapdragon 865 SoCs.  And others have tested it on Snapdragon 850,
Snapdragon 855, and Snapdragon 865 (see the Tested-by tags).

This is based very loosely on the vendor-provided driver in the kernel
source code for the Pixel 3, but I've greatly simplified it.  Also, for now
I've only included support for major version 3 of ICE, since that's all I
have the hardware to test with the mainline kernel.  Plus it appears that
version 3 is easier to use than older versions of ICE.

For now, only allow using AES-256-XTS.  The hardware also declares support
for AES-128-XTS, AES-{128,256}-ECB, and AES-{128,256}-CBC (BitLocker
variant).  But none of these others are really useful, and they'd need to
be individually tested to be sure they worked properly.

This commit also changes the name of the loadable module from "ufs-qcom" to
"ufs_qcom", as this is necessary to compile it from multiple source files
(unless we were to rename ufs-qcom.c).
