aa5ad10f6c SCSI misc on 20221213
Updates to the usual drivers (target, ufs, smartpqi, lpfc).  There are
 some core changes, mostly around reworking some of our user context
 assumptions in device put and moving some code around.  The remaining
 updates are bug fixes and minor changes.

78316e9dfc scsi: mpt3sas: Fix possible resource leaks in mpt3sas_transport_port_add()
In mpt3sas_transport_port_add(), if sas_rphy_add() returns error,
sas_rphy_free() needs be called to free the resource allocated in
sas_end_device_alloc(). Otherwise a kernel crash will happen:

Unable to handle kernel NULL pointer dereference at virtual address 0000000000000108

Because transport_add_device() is not called when sas_rphy_add() fails, the
device is not added. When sas_rphy_remove() is subsequently called to
remove the device in the remove() path, a NULL pointer dereference happens.

1a2dcbdde8 scsi: mpt3sas: re-do lost mpt3sas DMA mask fix
This is a re-do of commit e0e0747de0ea ("scsi: mpt3sas: Fix return value
check of dma_get_required_mask()"), which I ended up undoing in a
mis-merge in commit 62e6e5940c0c ("Merge tag 'scsi-misc' of
git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi").

The original commit message was

  scsi: mpt3sas: Fix return value check of dma_get_required_mask()

  Fix the incorrect return value check of dma_get_required_mask().  Due to
  this incorrect check, the driver was always setting the DMA mask to 63 bit.

and this fix was lost when I mis-merged the conflict with commit

62e6e5940c SCSI misc on 20221007
Updates to the usual drivers (qla2xxx, lpfc, ufs, hisi_sas, mpi3mr,
 mpt3sas, target); the biggest change (from my biased viewpoint) being
 that the mpi3mr now attached to the SAS transport class, making it the
 first fusion type device to do so.  Beyond the usual bug fixing and
 security class reworks, there aren't a huge number of core changes.

746fc76b82 SCSI misc on 20220804
Updates to the usual drivers (ufs, qla2xx, target, lpfc, smartpqi,
 mpi3mr).  The main driver change that might cause issues on down the
 road is the conversion of some of our oldest surviving drivers to the
 DMA API (should only affect m68k).  The only major core change is the
 rework of async resume; the rest are either completely trivial or for
 updating deprecated APIs.

0fde22c542 scsi: mpt3sas: Stop fw fault watchdog work item during system shutdown
During system shutdown or reboot, mpt3sas will reset the firmware back to
ready state. However, the driver leaves running a watchdog work item
intended to keep the firmware in operational state. This causes a second,
unneeded reset on shutdown and moves the firmware back to operational
instead of in ready state as intended. And if the mpt3sas_fwfault_debug
module parameter is set, this extra reset also panics the system.

mpt3sas's scsih_shutdown needs to stop the watchdog before resetting the
firmware back to ready state.

120f1d95ef scsi: mpt3sas: Fix out-of-bounds compiler warning
I'm facing this warning when building for the parisc64 architecture:

drivers/scsi/mpt3sas/mpt3sas_base.c: In function ‘_base_make_ioc_operational’:
drivers/scsi/mpt3sas/mpt3sas_base.c:5396:40: warning: array subscript ‘Mpi2SasIOUnitPage1_t {aka struct _MPI2_CONFIG_PAGE_SASIOUNIT_1}[0]’ is partly outside array bounds of ‘unsigned char[20]’ [-Warray-bounds]
 5396 |             (le16_to_cpu(sas_iounit_pg1->SASWideMaxQueueDepth)) ?
drivers/scsi/mpt3sas/mpt3sas_base.c:5382:26: note: referencing an object of size 20 allocated by ‘kzalloc’
 5382 |         sas_iounit_pg1 = kzalloc(sz, GFP_KERNEL);
      |                          ^~~~~~~~~~~~~~~~~~~~~~~

The problem is, that only 20 bytes are allocated with kmalloc(), which is
sufficient to hold the bytes which are needed.  Nevertheless, gcc complains
because the whole Mpi2SasIOUnitPage1_t struct is 32 bytes in size and thus
doesn't fit into those 20 bytes.

This patch simply allocates all 32 bytes (instead of 20) and thus avoids
the warning. There is no functional change introduced by this patch.

While touching the code I cleaned up to calculation of max_wideport_qd,
max_narrowport_qd and max_sata_qd to make it easier readable.

Test successfully tested on a HP C8000 PA-RISC workstation with 64-bit
kernel.

The functions _base_readl_aero() and _base_readl() used for an adapter
base_readl() method are implemented using a regular readl() call which
internally performs a conversion to CPU endianness (le32_to_cpu()) of
the values read. The users of the ioc base_readl() method should thus
not convert again the values read using le16_to_cpu().

Fix this by introducing the local variable port_id to store the port ID

is then used in the call to ioc_info() instead of dereferencing the freed

This is caused by mpt3sas_base_sync_reply_irqs() using an invalid reply_q
pointer outside of the list_for_each_entry() loop. At the end of the full
list traversal the pointer is invalid.

Move the _base_process_reply_queue() call inside of the loop.

When scsi_dma_map() fails by returning a sges_left value less than zero,
the amount of logging produced can be extremely high.  In a recent end-user
environment, 1200 messages per second were being sent to the log buffer.
This eventually overwhelmed the system and it stalled.

These error messages are not needed. Remove them.

fdb8ed13a7 scsi: mpt3sas: Use irq_set_affinity_and_hint()
The driver uses irq_set_affinity_hint() specifically for the high IOPS
queue interrupts for two purposes:

 - To set the affinity_hint which is consumed by the userspace for
   distributing the interrupts

 - To apply an affinity that it provides

The driver enforces its own affinity to bind the high IOPS queue interrupts
to the local NUMA node. However, irq_set_affinity_hint() applying the
provided cpumask as an affinity (if not NULL) for the interrupt is an
undocumented side effect.

To remove this side effect irq_set_affinity_hint() has been marked
as deprecated and new interfaces have been introduced. Hence, replace the
irq_set_affinity_hint() with the new interface irq_set_affinity_and_hint()
where the provided mask needs to be applied as the affinity and
affinity_hint pointer needs to be set and replace with
irq_update_affinity_hint() where only affinity_hint needs to be updated.

5ecae9f8c7 scsi: mpt3sas: Fix incorrect system timestamp
For updating the IOC firmware's timestamp with system timestamp, the driver
issues the Mpi26IoUnitControlRequest message. While framing the
Mpi26IoUnitControlRequest, the driver should copy the lower 32 bits of the
current timestamp into IOCParameterValue field and the higher 32 bits into
Reserved7 field.

91202a01a2 scsi: mpt3sas: Fix system going into read-only mode
While determining the SAS address of a drive, the driver checks whether the
handle number is less than the HBA phy count or not. If the handle number
is less than the HBA phy count then driver assumes that this handle belongs
to HBA and hence it assigns the HBA SAS address.

During IOC firmware downgrade operation, if the number of HBA phys is
reduced and the OS drive's device handle drops below the phy count while
determining the drive's SAS address, the driver ends up using the HBA's SAS
address. This leads to a mismatch of drive's SAS address and hence the
driver unregisters the OS drive and the system goes into read-only mode.

Update the IOC's num_phys to the HBA phy count provided by actual loaded
firmware.

0ee4ba13e0 scsi: mpt3sas: Fix kernel panic during drive powercycle test
While looping over shost's sdev list it is possible that one
of the drives is getting removed and its sas_target object is
freed but its sdev object remains intact.

Consequently, a kernel panic can occur while the driver is trying to access
the sas_address field of sas_target object without also checking the
sas_target object for NULL.

 target, megaraid_sas, hisi_sas, qla2xxx) and minor updates and bug
 fixes.  Notable core changes are the removal of scsi->tag which caused
 some churn in obsolete drivers and a sweep through all drivers to call
 scsi_done() directly instead of scsi->done() which removes a pointer
 indirection from the hot path and a move to register core sysfs files
 earlier, which means they're available to KOBJ_ADD processing, which
 necessitates switching all drivers to using attribute groups.
