531643fcd9 SCSI fixes on 20241019
Fixes all in drivers. The largest is the mpi3mr which corrects a phy
 count limit that should only apply to the controller but was being
 incorrectly applied to expander phys.

b9e63d6c7c scsi: mpi3mr: Validate SAS port assignments
A sanity check on phy_mask was added in commit 3668651def ("scsi:
mpi3mr: Sanitise num_phys"). This causes warning messages when more than
64 phys are detected and devices connected to phys greater than 64 are
dropped.

The phy_mask bitmap is only needed for controller phys and not required
for expander phys. Controller phys can go up to a maximum of 64 and
therefore u64 is good enough to contain phy_mask bitmap.

To suppress those warnings and allow devices to be discovered as before
the offending commit, restrict the phy_mask setting and lowest phy
setting only to the controller phys.

4616a4b3cb scsi: mpi3mr: Improve wait logic while controller transitions to READY state
During controller transitioning to READY state, if the controller is found
in transient states ("becoming ready" or "reset requested"), driver waits
for 510 secs even if the controller transitions out of these states
early. This causes an unnecessary delay of 510 secs in the overall firmware
initialization sequence.

Poll the controller state periodically (every 100 milliseconds) while
waiting for the controller to come out of the mentioned transient
states. Once the controller transits out of the transient states, come out
of the wait loop.

Commit 0c52310f26 ("hrtimer: Ignore slack time for RT tasks in
schedule_hrtimeout_range()") effectivelly shortens a sleep in a polling
function in the driver.  That is causing a performance regression as the
new value of just 2us is too low, in certain tests the perf drop is ~30%.
Fix this by adjusting the sleep to 20us (close to the previous value).

70302fc7ad Merge patch series "Simplify multiple create*_workqueue() invocations"
Bart Van Assche <bvanassche@acm.org> says:

Hi Martin,

Multiple SCSI drivers use snprintf() to format a workqueue name before
invoking one of the create*_workqueue() macros. This patch series
simplifies such code by passing the format string and arguments to
alloc_workqueue(). Additionally, the structure members that are only
used as a temporary buffer for formatting workqueue names are
removed. Please consider this patch series for the next merge window.

Thanks,

Bart.

b97c0741c7 scsi: Expand all create*_workqueue() invocations
The workqueue maintainer wants to remove the create*_workqueue() macros
because these macros always set the WQ_MEM_RECLAIM flag and because these
only support literal workqueue names. Hence this patch that replaces the
create*_workqueue() invocations with the definition of this macro. The
WQ_MEM_RECLAIM flag has been retained because I think that flag is necessary
for workqueues created by storage drivers. This patch has been generated by
running spatch and git clang-format. spatch has been invoked as follows:

spatch --in-place --sp-file expand-create-workqueue.spatch $(git grep -lEw 'create_(freezable_|singlethread_|)workqueue' */scsi */ufs)

The contents of the expand-create-workqueue.spatch file is as follows:

8c6b808c8c scsi: mpi3mr: Avoid MAX_PAGE_ORDER WARNING for buffer allocations
Commit fc44449411 ("scsi: mpi3mr: HDB allocation and posting for hardware
and firmware buffers") added mpi3mr_alloc_diag_bufs() which calls
dma_alloc_coherent() to allocate the trace buffer and the firmware
buffer. mpi3mr_alloc_diag_bufs() decides the buffer sizes from the driver
configuration. In my environment, the sizes are 8MB. With the sizes,
dma_alloc_coherent() fails and report this WARNING:

    WARNING: CPU: 4 PID: 438 at mm/page_alloc.c:4676 __alloc_pages_noprof+0x52f/0x640

The WARNING indicates that the order of the allocation size is larger than
MAX_PAGE_ORDER. After this failure, mpi3mr_alloc_diag_bufs() reduces the
buffer sizes and retries dma_alloc_coherent(). In the end, the buffer
allocations succeed with 4MB size in my environment, which corresponds to
MAX_PAGE_ORDER=10. Though the allocations succeed, the WARNING message is
misleading and should be avoided.

To avoid the WARNING, check the orders of the buffer allocation sizes
before calling dma_alloc_coherent(). If the orders are larger than
MAX_PAGE_ORDER, fall back to the retry path.

lock does not work as expected. Also, the kernel reports the message below
when lockdep is enabled.

    INFO: trying to register non-static key.
    The code is fine but needs lockdep annotation, or maybe
    you didn't initialize this object before use?

To fix the issue and to avoid the INFO message, add the missing

1abc900ddd scsi: mpi3mr: Avoid IOMMU page faults on REPORT ZONES
Some firmware versions of the 9600 series SAS HBA byte-swap the REPORT
ZONES command reply buffer from ATA-ZAC devices by directly accessing the
buffer in the host memory. This does not respect the default command DMA
direction and causes IOMMU page faults on architectures with an IOMMU
enforcing write-only mappings for DMA_FROM_DEVICE DMA direction (e.g. AMD
hosts), leading to the device capacity to be dropped to 0:

scsi 18:0:58:0: Direct-Access-ZBC ATA      WDC  WSH722626AL W930 PQ: 0 ANSI: 7

sd 18:0:58:0: [sdj] Attached SCSI disk

Avoid this issue by always mapping the buffer of REPORT ZONES commands
using DMA_BIDIRECTIONAL, that is, using a read-write IOMMU mapping.

90e6f08915 scsi: mpi3mr: Fix ATA NCQ priority support
The function mpi3mr_qcmd() of the mpi3mr driver is able to indicate to
the HBA if a read or write command directed at an ATA device should be
translated to an NCQ read/write command with the high prioiryt bit set
when the request uses the RT priority class and the user has enabled NCQ
priority through sysfs.

However, unlike the mpt3sas driver, the mpi3mr driver does not define
the sas_ncq_prio_supported and sas_ncq_prio_enable sysfs attributes, so
the ncq_prio_enable field of struct mpi3mr_sdev_priv_data is never
actually set and NCQ Priority cannot ever be used.

Fix this by defining these missing atributes to allow a user to check if
an ATA device supports NCQ priority and to enable/disable the use of NCQ
priority. To do this, lift the function scsih_ncq_prio_supp() out of the
mpt3sas driver and make it the generic SCSI SAS transport function
sas_ata_ncq_prio_supported(). Nothing in that function is hardware
specific, so this function can be used in both the mpt3sas driver and
the mpi3mr driver.

9f365cb8bb scsi: mpi3mr: Use proper format specifier in mpi3mr_sas_port_add()
When building for a 32-bit platform such as ARM or i386, for which size_t
is unsigned int, there is a warning due to using an unsigned long format
specifier:

  drivers/scsi/mpi3mr/mpi3mr_transport.c:1370:11: error: format specifies type 'unsigned long' but the argument has type 'unsigned int' [-Werror,-Wformat]
   1369 |                         ioc_warn(mrioc, "skipping port %u, max allowed value is %lu\n",
        |                                                                                 ~~~
        |                                                                                 %u

Use the proper format specifier for size_t, %zu, to resolve the warning for
all platforms.

0069455bcb fix missing vmalloc.h includes
Patch series "Memory allocation profiling", v6.

Overview:
Low overhead [1] per-callsite memory allocation profiling. Not just for
debug kernels, overhead low enough to be deployed in production.

Example output:

Usage:
kconfig options:
 - CONFIG_MEM_ALLOC_PROFILING
 - CONFIG_MEM_ALLOC_PROFILING_ENABLED_BY_DEFAULT
 - CONFIG_MEM_ALLOC_PROFILING_DEBUG
   adds warnings for allocations that weren't accounted because of a
   missing annotation

sysctl:
  /proc/sys/vm/mem_profiling

Runtime info:
  /proc/allocinfo

Notes:

[1]: Overhead
To measure the overhead we are comparing the following configurations:
(1) Baseline with CONFIG_MEMCG_KMEM=n
(2) Disabled by default (CONFIG_MEM_ALLOC_PROFILING=y &&
    CONFIG_MEM_ALLOC_PROFILING_BY_DEFAULT=n)
(3) Enabled by default (CONFIG_MEM_ALLOC_PROFILING=y &&
    CONFIG_MEM_ALLOC_PROFILING_BY_DEFAULT=y)
(4) Enabled at runtime (CONFIG_MEM_ALLOC_PROFILING=y &&
    CONFIG_MEM_ALLOC_PROFILING_BY_DEFAULT=n && /proc/sys/vm/mem_profiling=1)
(5) Baseline with CONFIG_MEMCG_KMEM=y && allocating with __GFP_ACCOUNT
(6) Disabled by default (CONFIG_MEM_ALLOC_PROFILING=y &&
    CONFIG_MEM_ALLOC_PROFILING_BY_DEFAULT=n)  && CONFIG_MEMCG_KMEM=y
(7) Enabled by default (CONFIG_MEM_ALLOC_PROFILING=y &&
    CONFIG_MEM_ALLOC_PROFILING_BY_DEFAULT=y) && CONFIG_MEMCG_KMEM=y

Performance overhead:
To evaluate performance we implemented an in-kernel test executing
multiple get_free_page/free_page and kmalloc/kfree calls with allocation
sizes growing from 8 to 240 bytes with CPU frequency set to max and CPU
affinity set to a specific CPU to minimize the noise. Below are results
from running the test on Ubuntu 22.04.2 LTS with 6.8.0-rc1 kernel on
56 core Intel Xeon:

                        kmalloc                 pgalloc
(1 baseline)            6.764s                  16.902s
(2 default disabled)    6.793s  (+0.43%)        17.007s (+0.62%)
(3 default enabled)     7.197s  (+6.40%)        23.666s (+40.02%)
(4 runtime enabled)     7.405s  (+9.48%)        23.901s (+41.41%)
(5 memcg)               13.388s (+97.94%)       48.460s (+186.71%)
(6 def disabled+memcg)  13.332s (+97.10%)       48.105s (+184.61%)
(7 def enabled+memcg)   13.446s (+98.78%)       54.963s (+225.18%)

Memory consumption on a 56 core Intel CPU with 125GB of memory:
Code tags:           192 kB
PageExts:         262144 kB (256MB)
SlabExts:           9876 kB (9.6MB)
PcpuExts:            512 kB (0.5MB)

Total overhead is 0.2% of total memory.

This patch (of 37):

The next patch drops vmalloc.h from a system header in order to fix a
circular dependency; this adds it to all the files that were pulling it in
implicitly.

d4309246cf scsi: mpi3mr: Avoid possible run-time warning with long manufacturer strings
The prior use of strscpy() here expected the manufacture_reply strings to
be NUL-terminated, but it is possible they are not, as the code pattern
here shows, e.g., edev->vendor_id being exactly 1 character larger than
manufacture_reply->vendor_id, and the strscpy() was copying only up to
the size of the source character array. Replace this with memtostr(),
which is the unambiguous way to convert a maybe not-NUL-terminated
character array into a NUL-terminated string.

Switch to the ->device_configure method instead of ->slave_configure and
update the block limits on the passed in queue_limits instead of using the
per-limit accessors.

Note that mpi3mr also updates the limits from an event handler that
iterates all SCSI devices.  This is also updated to use the queue_limits,
but the complete locking of this path probably means it already is
completely broken and needs a proper audit.
