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).

1bc726e26e scsi: ufs: Add program_key() variant op
On Snapdragon SoCs, the Linux kernel isn't permitted to directly access the
standard UFS crypto configuration registers.  Instead, programming and
evicting keys must be done through vendor-specific SMC calls.

To support this hardware, add a ->program_key() method to 'struct
ufs_hba_variant_ops'.  This allows overriding the UFS standard key
programming / eviction procedure.

083dd788e4 scsi: ufs-qcom: Name the dev_ref_clk_ctrl registers
In preparation for adding another optional register range to the ufs-qcom
driver, name the existing optional register range "dev_ref_clk_ctrl_mem".
This allows the driver to refer to the optional register ranges by name
rather than index.

No device-tree files actually have to be updated due to this change, since
none of them actually declares these registers.

bdb5d8ec47 qed, qede, qedf: convert link mode from u32 to ETHTOOL_LINK_MODE
Currently qed driver already ran out of 32 bits to store link modes,
and this doesn't allow to add and support more speeds.
Convert custom link mode to generic Ethtool bitmap and definitions
(convenient Phylink shorthands are used for elegance and readability).
This allowed us to drop all conversions/mappings between the driver
and Ethtool.

This involves changes in qede and qedf as well, as they used definitions
from shared "qed_if.h".

3f649ab728 treewide: Remove uninitialized_var() usage
Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.

In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:

git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
	xargs perl -pi -e \
		's/\buninitialized_var\(([^\)]+)\)/\1/g;
		 s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'

drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.

No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.

659bf827ba block: add max_active_zones to blk-sysfs
Add a new max_active zones definition in the sysfs documentation.
This definition will be common for all devices utilizing the zoned block
device support in the kernel.

Export max_active_zones according to this new definition for NVMe Zoned
Namespace devices, ZAC ATA devices (which are treated as SCSI devices by
the kernel), and ZBC SCSI devices.

Add the new max_active_zones member to struct request_queue, rather
than as a queue limit, since this property cannot be split across stacking
drivers.

For SCSI devices, even though max active zones is not part of the ZBC/ZAC
spec, export max_active_zones as 0, signifying "no limit".

1f54682314 scsi: lpfc: NVMe remote port devloss_tmo from lldd
nvme-fc allows the driver to specify a default devloss_tmo value when
registering the remote port. The lpfc driver is currently not doing so,
although it is implementing a driver internal node loss value of 30s which
also is used on the SCSI FC remote port. As no devloss_tmo is set, the
nvme-fc transport defaults to 60s. So there are competing timers.

Additionally, due to the competing timers, it is possible the NVMe rport is
removed but the SCSI rport remains. It is possible that the SCSI FC rport,
which was registered for the NVMe port even if it doesn't utilize the SCSI
protocol, had been tuned to not match either the 60s (nvme-fc default) or
30s (lldd default), it gets out of whack. The lldd will defer to the SCSI
FC rport as long as the SCSI FC rport has not had its devloss_tmo expire.

Correct the situation by specifying a default devloss_tmo to the nvme-fc
transport when registering the rport.  Take the value from the SCSI FC
rport if it exists, otherwise use the driver default.

30f67481a1 scsi: scsi_debug: Update documentation url and bump version
This driver maintains a version number which is cross-referenced in the
documentation (e.g. to indicate when features are added or changed) and
exposed through the responses to various SCSI commands. For example the
version number is use as the Product Revision number in standard SCSI
INQUIRY responses issued by this driver. The version date string is placed
in a vendor specific area in each standard SCSI INQUIRY response. This
patch bumps both.

Update the driver documentation URL that appears at the top of the driver
source file.

3a90a63d02 scsi: scsi_debug: every_nth triggered error injection
This patch simplifies, or at least makes more consistent, the way setting
the every_nth parameter injects errors. Here is a list of 'opts' flags and
in which cases they inject errors when abs(every_nth)%command_count == 0 is
reached:

  - OPT_RECOVERED_ERR: issued on READ(*)s, WRITE(*)s and
                       WRITE_SCATTEREDs
  - OPT_DIF_ERR:       issued on READ(*)s, WRITE(*)s and
                       WRITE_SCATTEREDs
  - OPT_DIX_ERR:       issued on READ(*)s, WRITE(*)s and
                       WRITE_SCATTEREDs
  - OPT_SHORT_TRANSFER: issued on READ(*)s
  - OPT_TRANSPORT_ERR: issued on all commands
  - OPT_CMD_ABORT:     issued on all commands

The other uses of every_nth were not modified.

Previously if, for example, OPT_SHORT_TRANSFER was armed then if
(abs(every_nth) % command_count == 0) occurred during a command that was
_not_ a READ, then no error injection occurred. This behaviour puzzled
several testers. Now a global "inject_pending" flag is set and the _next_
READ will get hit and that flag is cleared. OPT_RECOVERED_ERR, OPT_DIF_ERR
and OPT_DIX_ERR have similar behaviour. A downside of this is that there
might be a hang-over pending injection that gets triggered by a following
test.

Also expand the every_nth runtime parameter so that it can take hex value

c10fa55f5e scsi: scsi_debug: Support hostwide tags
Many SCSI HBAs support a hostwide tagset, whereby each command submitted to
the HW from all submission queues must have a unique tag identifier.

Normally this unique tag will be in the range [0, max queue], where "max
queue" is the depth of each of the submission queues.

Add support for this hostwide tag feature, via module parameter
"host_max_queue". A non-zero value means that the feature is enabled. In
this case, the submission queues are not exposed to upper layer, i.e. from
blk-mq prespective, the device has a single hw queue. There are 2 reasons
for this:

 a. It is assumed that the host can support nr_hw_queues * can_queue
    commands, but this is not true for hostwide tags

 b. For nr_hw_queues != 0, the request tag is not unique over all HW
    queues, and some HBA drivers want to use this tag for the hostwide tag

However, like many SCSI HBA drivers today - megaraid sas being an example -
the full set of HW submission queues are still used in the LLDD driver. So
instead of using a complicated "reply_map" to create a per-CPU submission
queue mapping like megaraid_sas (as it depends on a PCI device + MSIs) -
use a simple algorithm:

    hwq = cpu % queue count

If the host_max_queue param is set non-zero, then the max queue depth is
fixed at this value also.

If and when hostwide shared tags are supported in blk-mq/scsi mid-layer,
then the policy to set nr_hw_queues = 0 for hostwide tags can be revised.

However MediaTek UFS host requires a vendor-specific hce_enable operation
to allow crypto-related registers being accessed normally in kernel.  After
this step, MediaTek UFS host can work as standard-compliant host for
inline-encryption related functions.

17105d959b scsi: lpfc: Fix interrupt assignments when multiple vectors are supported on same CPU
With certain platforms its possible pci_alloc_irq_vectors() may affinitize
irq vectors to multiple (all?) CPUs. The driver is currently assuming
exclusivity and vectors being doled out to different CPUs and is assigning
primary ownership of each vector to the first CPU in the mask.  The code
doesn't bother to check if the CPU already owns a vector and will
unconditionally overwrite the CPU to vector mapping. This causes the
relationships between eq's and cq's to get confused and gets worse when
CPUs start to offline. The net results are interrupts are skipped resulting
in mailbox timeouts and there are oopses in CPU offling flows.

Fix this changing up the primary vector assignment. Now assign the eq to a
CPU only if it is the CPU in the mask that does not have a prior
assignment. And once the primary ownership is assigned, break from the
loop. For CPUs that may have been set before but not the primary owner, the
lpfc_cpu_affinity_check() routine will balance the CPU to eq assignment.

df043c745e scsi: ufs: Add inline encryption support to UFS
Wire up ufshcd.c with the UFS Crypto API, the block layer inline encryption
additions and the keyslot manager.

Many existing inline crypto devices require some additional behaviour not
specified in the UFSHCI v2.1 specification - as such the vendor specific
drivers will need to be updated where necessary to make it possible to use
those devices. Some of these changes have already been proposed upstream,
such as for the Qualcomm 845 SoC at
https://lkml.kernel.org/linux-scsi/20200501045111.665881-1-ebiggers@kernel.org/
and for ufs-mediatek at
https://lkml.kernel.org/linux-scsi/20200304022101.14165-1-stanley.chu@mediatek.com/

This patch has been tested on the db845c, sm8150-mtp and sm8250-mtp
(which have Qualcomm chipsets) and on some mediatek chipsets using these
aforementioned vendor specific driver updates.

a lot of hardware requires some special handling that's not specified in

c06de6e28c scsi: docs: Remove invalid link and update text for zfcp kernel config
IBM decided to retire a lot of the content that was previously hosted on
"developerworks", and so some of the links we've used for documentation are
now dead or redirect to some general landing page with no correlation to
what the links were meant to provide.

Change the provided link in the Kconfig file for zfcp to rather refer to
our device drivers book that we regularly update and publish for free, and
whose name hasn't been changed since it was first published.

Our hardware is also not called "IBM eServer zSeries" anymore - in fact, it
hasn't been called like that since 2006. Use a broader term that covers
different server names over time.

Lastly, add a short paragraph about how our HBAs are typically named, to
have some more tangible references.

BRM_status_show() has several error branches, but none of them record the
error in the error return.

Also while at it remove the manual mutex_unlock() of the pci_access_mutex
in case of an ongoing pci error recovery or host removal and jump to the
cleanup label instead.

Note: We can safely jump to out from here as io_unit_pg3 is initialized to
NULL and if it hasn't been allocated, kfree() skips the NULL pointer.

16d79cd4e2 PCI: Use 'pci_channel_state_t' instead of 'enum pci_channel_state'
The method struct pci_error_handlers.error_detected() is defined and
documented as taking an 'enum pci_channel_state' for the second argument,
but most drivers use 'pci_channel_state_t' instead.

This 'pci_channel_state_t' is not a typedef for the enum but a typedef for
a bitwise type in order to have better/stricter typechecking.

Consolidate everything by using 'pci_channel_state_t' in the method's
definition, in the related helpers and in the drivers.

Enforce use of 'pci_channel_state_t' by replacing 'enum pci_channel_state'
with an anonymous 'enum'.

Note: Currently, from a typechecking point of view this patch changes
nothing because only the constants defined by the enum are bitwise, not the
enum itself (sparse doesn't have the notion of 'bitwise enum'). This may
change in some not too far future, hence the patch.

Commit 3ce419662d ("scsi: iscsi: Register sysfs for iscsi workqueue")
enabled 'cpumask' support for iSCSI workqueues. However, it is unnecessary
to set max_active = 2 since 'cpumask' can still be modified when max_active
is 1.

This patch sets max_active to 1 so as to keep the same behaviour as before.

372c187b8a scsi: lpfc: Add an internal trace log buffer
The current logging methods typically end up requesting a reproduction with
a different logging level set to figure out what happened. This was mainly
by design to not clutter the kernel log messages with things that were
typically not interesting and the messages themselves could cause other
issues.

When looking to make a better system, it was seen that in many cases when
more data was wanted was when another message, usually at KERN_ERR level,
was logged.  And in most cases, what the additional logging that was then
enabled was typically. Most of these areas fell into the discovery machine.

Based on this summary, the following design has been put in place: The
driver will maintain an internal log (256 elements of 256 bytes).  The
"additional logging" messages that are usually enabled in a reproduction
will be changed to now log all the time to the internal log.  A new logging
level is defined - LOG_TRACE_EVENT.  When this level is set (it is not by
default) and a message marked as KERN_ERR is logged, all the messages in
the internal log will be dumped to the kernel log before the KERN_ERR
message is logged.

There is a timestamp on each message added to the internal log. However,
this timestamp is not converted to wall time when logged. The value of the
timestamp is solely to give a crude time reference for the messages.

317aeb83c9 scsi: lpfc: Add blk_io_poll support for latency improvment
Although the existing implementation is very good at high I/O load, on
tests involving light load, especially on only a few hardware queues,
latency was a little higher than it can be due to using workqueue
scheduling. Other tasks in the system can delay handling.

Change the lower level to use irq_poll by default which uses a softirq for
I/O completion. This gives better latency as variance in when the cq is
processed is reduced over the workqueue interface. However, as high load is
better served by not being in softirq when the CPU is loaded, work queues
are still used under high I/O load.

03dbfe0668 scsi: lpfc: Fix shost refcount mismatch when deleting vport
When vports are deleted, it is observed that there is memory/kthread
leakage as the vport isn't fully being released.

There is a shost reference taken in scsi_add_host_dma that is not released
during scsi_remove_host. It was noticed that other drivers resolve this by
doing a scsi_host_put after calling scsi_remove_host.

The vport_delete routine is taking two references one that corresponds to
an access to the scsi_host in the vport_delete routine and another that is
released after the adapter mailbox command completes that destroys the VPI
that corresponds to the vport.

Remove one of the references taken such that the second reference that is
put will complete the missing scsi_add_host_dma reference and the shost
will be terminated.

9806c984d4 scsi: lpfc: Fix NVMe rport deregister and registration during ADISC
During driver unload/reload testing, the NVMe initiator would not
re-establish connectivity to NVMe controllers on reload.

The failing NVMe array supports concurrent FCP and NVMe operation via
different nport_id's. The array was repeatedly sending an ADISC every 2
seconds after PLOGI completed and while NVMe subsystems were executing
discovery. The target would continue this state for roughly 45 seconds.

The driver's current behavior on ADISC receipt is to validate a the ADISC
vs the device and issue a RESUME_RPI to restore transmission. The receipt
of the ADISC effectively caused a driver to take actions similar to a
logout and login for the remote port, causing the deregistration of the
nvme rport and a subsequent re-registration.  This caused a constant reset
and re-connect of the NVMe controller while this 45s window occurred. There
was no need for the state changes as ADISC does not change login state.

This patch corrects this behavior by validating if the remoteport is
already logged in (MAPPED) and when true, avoids the call to set the ndlp
state to MAPPED, which triggers the unreg/re-reg. Thus ADISC does not
change the login state of the node.

The rc variable was initially assigned a value but in several cases, when

In code-reviewing this routine, it could use some cleanup:

 - Setting the initialization value to -ENODEV is a much better choice and
   lessens code in the routine.

 - The wasn't tracking logic errors vs no error and mailbox failure.
   Better to resolve by adding a status to track the mailbox failure
   and merge it with the logic error when the routine returns.

65c7636943 blk-mq: pass request queue into get/put budget callback
blk-mq budget is abstract from scsi's device queue depth, and it is
always per-request-queue instead of hctx.

It can be quite absurd to get a budget from one hctx, then dequeue a
request from scheduler queue, and this request may not belong to this
hctx, at least for bfq and deadline.

So fix the mess and always pass request queue to get/put budget
callback.

b7a80dac0f scsi: ufs: ufs-exynos: Remove an unnecessary NULL check
The "head" pointer can't be NULL because it points to an address in the
middle of a ufs_hba struct.  Looking at this code, probably someone would
wonder if the intent was to check whether "hba" is NULL, but "hba" isn't
NULL and the check can just be removed.

d20df83b66 PCI: Convert PCIe capability PCIBIOS errors to errno
The PCI config accessors (pci_read_config_word(), et al) return
PCIBIOS_SUCCESSFUL (zero) or positive error values like
PCIBIOS_FUNC_NOT_SUPPORTED.

The PCIe capability accessors (pcie_capability_read_word(), et al)
similarly return PCIBIOS errors, but some callers assume they return
generic errno values like -EINVAL.

For example, the Myri-10G probe function returns a positive PCIBIOS error
if the pcie_capability_clear_and_set_word() in pcie_set_readrq() fails:

  myri10ge_probe
    status = pcie_set_readrq
      return pcie_capability_clear_and_set_word
    if (status)
      return status

A positive return from a PCI driver probe function would cause a "Driver
probe function unexpectedly returned" warning from local_pci_probe()
instead of the desired probe failure.

Convert PCIBIOS errors to generic errno for all callers of:

  pcie_capability_read_word
  pcie_capability_read_dword
  pcie_capability_write_word
  pcie_capability_write_dword
  pcie_capability_set_word
  pcie_capability_set_dword
  pcie_capability_clear_word
  pcie_capability_clear_dword
  pcie_capability_clear_and_set_word
  pcie_capability_clear_and_set_dword

that check the return code for anything other than zero.

15f73f5b3e blk-mq: move failure injection out of blk_mq_complete_request
Move the call to blk_should_fake_timeout out of blk_mq_complete_request
and into the drivers, skipping call sites that are obvious error
handlers, and remove the now superflous blk_mq_force_complete_rq helper.
This ensures we don't keep injecting errors into completions that just
terminate the Linux request after the hardware has been reset or the
command has been aborted.
