Prior to commit 1f4a4a19508d ("scsi: ibmvfc: Complete commands outside the
host/queue lock") responses to commands were completed sequentially with
the host lock held such that a command had a basic binary state of active
or free. It was therefore a simple affair of ensuring the assocaiated
ibmvfc_event to a VIOS response was valid by testing that it was not
already free. The lock relexation work to complete commands outside the
lock inadverdently made it a trinary command state such that a command is
either in flight, received and being completed, or completed and now
free. This breaks the stale command detection logic as a command may be
still marked active and been placed on the delayed completion list when a
second stale response for the same command arrives. This can lead to double
completions and list corruption. This issue was exposed by a recent VIOS
regression were a missing memory barrier could occasionally result in the
ibmvfc client receiving a duplicate response for the same command.
Fix the issue by introducing the atomic ibmvfc_event.active to track the
trinary state of a command. The state is explicitly set to 1 when a command
is successfully sent. The CRQ response handlers use
atomic_dec_if_positive() to test for stale responses and correctly
transition to the completion state when a active command is received.
Finally, atomic_dec_and_test() is used to sanity check transistions when
commands are freed as a result of a completion, or moved to the purge list
as a result of error handling or adapter reset.

Avoid printing a 'target allocation failed' error if the driver
target_alloc() callback function returns -ENXIO. This return value
indicates that the corresponding H:C:T:L entry is empty.
Removing this error reduces the scan time if the user issues SCAN_WILD_CARD
scan operation through sysfs parameter on a host with a lot of empty
H:C:T:L entries.
Avoiding the printk on -ENXIO matches the behavior of the other callback
functions during scanning.

The list_for_each_entry() iterator, "adapter" in this code, can never be
NULL. If we exit the loop without finding the correct adapter then
"adapter" points invalid memory that is an offset from the list head. This
will eventually lead to memory corruption and presumably a kernel crash.

The TMF timeout timer may trigger at the same time when the response from a
controller is being handled. When this happens the SAS task may get freed
before the response processing is finished.
Fix this by calling complete() only when SAS_TASK_STATE_DONE is not set.
A similar race condition was fixed in commit b90cd6f2b905 ("scsi: libsas:

CPU affinity control added with commit 39ae3edda325 ("scsi: target: core:
Make completion affinity configurable") makes target_complete_cmd() queue
work on a CPU based on se_tpg->se_tpg_wwn->cmd_compl_affinity state.
LIO's EXTENDED COPY worker is a special case in that read/write cmds are
dispatched using the global xcopy_pt_tpg, which carries a NULL se_tpg_wwn
pointer following initialization in target_xcopy_setup_pt().
The NULL xcopy_pt_tpg->se_tpg_wwn pointer is dereferenced on completion of
any EXTENDED COPY initiated read/write cmds. E.g using the libiscsi

The IOC firmware assumes that the host driver is still alive after shutdown
and continues to post events to host memory (due to faulty expander phy
links, etc). This leads to 0x2666 (a bus fault occurred during a host-IOC
memory access).
Perform an IOC soft reset as part of shutdown to disable event posting.

A ISCSI_IFACE_PARAM can have the same value as a ISCSI_NET_PARAM so when
iscsi_iface_attr_is_visible tries to figure out the type by just checking
the value, we can collide and return the wrong type. When we call into the
driver we might not match and return that we don't want attr visible in
sysfs. The patch fixes this by setting the type when we figure out what the

On remote cable pull, a zfcp_port keeps its status and only gets
ZFCP_STATUS_PORT_LINK_TEST added. Only after an ADISC timeout, we would
actually start port recovery and remove ZFCP_STATUS_COMMON_UNBLOCKED which
zfcp_sysfs_port_fc_security_show() detected and reported as "unknown"
instead of the old and possibly stale zfcp_port->connection_info.
Add check for ZFCP_STATUS_PORT_LINK_TEST for timely "unknown" report.

Commit 66a834d09293 ("scsi: core: Fix error handling of scsi_host_alloc()")
changed the allocation logic to call put_device() to perform host cleanup
with the assumption that IDA removal and stopping the kthread would
properly be performed in scsi_host_dev_release(). However, in the unlikely
case that the error handler thread fails to spawn, shost->ehandler is set
to ERR_PTR(-ENOMEM).
The error handler cleanup code in scsi_host_dev_release() will call
kthread_stop() if shost->ehandler != NULL which will always be the case
whether the kthread was successfully spawned or not. In the case that it
failed to spawn this has the nasty side effect of trying to dereference an
invalid pointer when kthread_stop() is called. The following splat provides
an example of this behavior in the wild:
scsi host11: error handler thread failed to spawn, error = -4

The kernel recovers in due course from missing Mlocked pages: but there
was no point in calling page_mlock() (formerly known as
try_to_munlock()) on a THP, because nothing got done even when it was
found to be mapped in another VM_LOCKED vma.
It's true that we need to be careful: Mlocked accounting of pte-mapped
THPs is too difficult (so consistently avoided); but Mlocked accounting
of only-pmd-mapped THPs is supposed to work, even when multiple mappings
are mlocked and munlocked or munmapped. Refine the tests.
There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so
page_mlock_one() does not even have to worry about that complication.
(I said the kernel recovers: but would page reclaim be likely to split
THP before rediscovering that it's VM_LOCKED? I've not followed that up)

TTU_SPLIT_FREEZE has just been deleted, so reword the comment about it
in mm/huge_memory.c; and TTU_IGNORE_ACCESS was removed in 5.11, so
delete the "recently referenced" comment from try_to_unmap_one() (once

Pull more perf tool updates from Arnaldo Carvalho de Melo:
"New features:
- Enable use of BPF counters with 'perf stat --for-each-cgroup',
using per-CPU 'cgroup-switch' events with an attached BPF program
that does aggregation per-cgroup in the kernel instead of using
per-cgroup perf events.
- Add Topdown metrics L2 events as default events in 'perf stat' for
systems having those events.
Hardware tracing:
- Add a config for max loops without consuming a packet in the Intel
PT packet decoder, set via 'perf config intel-pt.max-loops=N'
Hardware enablement:
- Disable misleading NMI watchdog message in 'perf stat' on hybrid
systems such as Intel Alder Lake.
- Add a dummy event on hybrid systems to collect metadata records.
- Add 24x7 nest metric events for the Power10 platform.
Fixes:
- Fix event parsing for PMUs starting with the same prefix.
- Fix the 'perf trace' 'trace' alias installation dir.
- Fix buffer size to report iregs in perf script python scripts,
supporting the extended registers in PowerPC.
- Fix overflow in elf_sec__is_text().
- Fix 's' on source line when disasm is empty in the annotation TUI,
accessible via 'perf annotate', 'perf report' and 'perf top'.
- Plug leaks in scandir() returned dirent entries in 'perf test' when
sorting the shell tests.
- Fix --task and --stat with pipe input in 'perf report'.
- Fix 'perf probe' use of debuginfo files by build id.
- If a DSO has both dynsym and symtab ELF sections, read from both
when loading the symbol table, fixing a problem processing Fedora
32 glibc DSOs.
Libraries:
- Add grouping of events to libperf, from code in tools/perf,
allowing libperf users to use that mode.
Misc:
- Filter plt stubs from the 'perf probe --functions' output.
- Update UAPI header copies for asound, DRM, mman-common.h and the
ones affected by the quotactl_fd syscall"

Commit dbbee9d5cd83 ("mm/page_alloc: convert per-cpu list protection to
local_lock") folded in a workaround patch for pahole that was unable to
deal with zero-sized percpu structures.
A superior workaround is achieved with commit a0b8200d06ad ("kbuild:
skip per-CPU BTF generation for pahole v1.18-v1.21").
This patch reverts the dummy field and the pahole version check.

git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock
Pull memblock fix from Mike Rapoport:
"This is a fix for the rework of ARM's pfn_valid() implementation
merged during this merge window.
Don't abuse pfn_valid() to check if pfn is in RAM
The semantics of pfn_valid() is to check presence of the memory map
for a PFN and not whether a PFN is in RAM. The memory map may be
present for a hole in the physical memory and if such hole corresponds
to an MMIO range, __arm_ioremap_pfn_caller() will produce a WARN() and
fail.
Use memblock_is_map_memory() instead of pfn_valid() to check if a PFN
is in RAM or not"

git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu
Pull percpu fix from Dennis Zhou:
"This is just a single change to fix percpu depopulation. The code
relied on depopulation code written specifically for the free path and
relied on vmalloc to do the tlb flush lazily. As we're modifying the
backing pages during the lifetime of a chunk, we need to also flush
the tlb accordingly.
Guenter Roeck reported this issue in [1] on mips. I believe we just
happen to be lucky given the much larger chunk sizes on x86 and
consequently less churning of this memory"

commit 03623b4b041c ("rtc: pcf2127: add tamper detection support")
added support for timestamp interrupts. However they are not being
handled in the irq handler. If a timestamp interrupt occurs it
results in kernel disabling the interrupt and displaying the call
trace:
[ 121.145580] irq 78: nobody cared (try booting with the "irqpoll" option)
...
[ 121.238087] [<00000000c4d69393>] irq_default_primary_handler threaded [<000000000a90d25b>] pcf2127_rtc_irq [rtc_pcf2127]
[ 121.248971] Disabling IRQ #78
Handle timestamp interrupts in pcf2127_rtc_irq(). Save time stamp
before clearing TSF1 and TSF2 flags so that it can't be overwritten.
Set a flag to mark if the timestamp is valid and only report to sysfs
if the flag is set. To mimic the hardware behavior, don’t save
another timestamp until the first one has been read by the userspace.
However, if the alarm irq is not configured, keep the old way of
handling timestamp interrupt in the timestamp0 sysfs calls.

The offset variable is checked by at91_rtc_readalarm(), but this check
is unnecessary because the previous check knew that the value of this
variable was not 0.
This removes that unnecessary offset variable checks.

s5m_check_peding_alarm_interrupt() in s5m_rtc_read_alarm() gets the return
value, but doesn't use it.
This modifies using the s5m_check_peding_alarm_interrupt()"s return value
as the s5m_rtc_read_alarm()'s return value.
