Added a new event handler to firmware sync reset, which is used to
support firmware sync reset flow on smart NIC. Adding this new stage to
the flow enables the firmware to ensure host PFs unload before ECPFs
unload, to avoid race of PFs recovery.
If firmware sends sync_reset_unload event to driver the driver should
unload and close all HW resources of the function. Once the driver
finishes unloading part, it can't get any more events from firmware as
event queues are closed, so it polls the reset state field to know when
to continue to next stage of the sync reset flow.
Added capability bit for supporting sync_reset_unload event.

Pull RCU fix from Paul McKenney:
"This fixes a spinlock-initialization regression in SRCU that causes
the SRCU notifier to fail.
The fix simply adds the initialization, but introduces a #ifdef
because there is no spinlock to initialize for the Tiny SRCU used in

Yes, it would be nice to abstract this somehow in order to hide it in

vfio-cdx driver enables IOCTLs for user space to query
MMIO regions for CDX devices and mmap them. This change
also adds support for reset of CDX devices. With VFIO
enabled on CDX devices, user-space applications can also
exercise DMA securely via IOMMU on these devices.
This change adds the VFIO CDX driver and enables the following
ioctls for CDX devices:
- VFIO_DEVICE_GET_INFO:
- VFIO_DEVICE_GET_REGION_INFO
- VFIO_DEVICE_RESET

scsi_target_block rework"
Martin Wilck <mwilck@suse.com> says:
This patch series addresses some issues we saw in a test setup with a
large number of SCSI LUNs. The first two patches simply increase the
number of available sg and bsg devices. 3-5 fix a large delay we
encountered between blocking a Fibre Channel remote port and the
dev_loss_tmo. 6 renames scsi_target_block() to scsi_block_targets(),
and makes additional changes to this API, as suggested in the review
of the v2 series. 7 improves a warning message.

All callers (fc_remote_port_delete(), __iscsi_block_session(),
__srp_start_tl_fail_timers(), srp_reconnect_rport(), snic_tgt_del()) pass
parent devices of scsi_target devices to scsi_target_block().
Rename the function to scsi_block_targets(), and simplify it by assuming
that it is always passed a parent device. Also, have callers pass the
Scsi_Host pointer to scsi_block_targets(), as every caller has this pointer
readily available.

In MCQ mode, when a device command uses a hardware queue shared with other
commands, a race condition may occur in the following scenario:
1. A device command is completed in CQx with CQE entry "e".
2. The interrupt handler copies the "cqe" pointer to "hba->dev_cmd.cqe"
and completes "hba->dev_cmd.complete".
3. The "ufshcd_wait_for_dev_cmd()" function is awakened and retrieves the
OCS value from "hba->dev_cmd.cqe".
However, there is a possibility that the CQE entry "e" will be overwritten
by newly completed commands in CQx, resulting in an incorrect OCS value
being received by "ufshcd_wait_for_dev_cmd()".
To avoid this race condition, the OCS value should be immediately copied to
the struct "lrb" of the device command. Then "ufshcd_wait_for_dev_cmd()"
can retrieve the OCS value from the struct "lrb".

The introduction of the macro IOPRIO_PRIO_LEVEL() in commit eca2040972b4
("scsi: block: ioprio: Clean up interface definition") results in an
iopriority level to always be masked using the macro IOPRIO_LEVEL_MASK, and
thus to the kernel always seeing an acceptable value for an I/O priority
level when checked in ioprio_check_cap(). Before this patch, this function
would return an error for some (but not all) invalid values for a level
valid range of [0..7].
Restore and improve the detection of invalid priority levels by introducing
the inline function ioprio_value() to check an ioprio class, level and hint
value before combining these fields into a single value to be used with
ioprio_set() or AIOs. If an invalid value for the class, level or hint of
an ioprio is detected, ioprio_value() returns an ioprio using the class
IOPRIO_CLASS_INVALID, indicating an invalid value and causing
ioprio_check_cap() to return -EINVAL.

Commits ffb1b4a41016 ("x86/unwind/orc: Add 'signal' field to ORC
metadata") and fb799447ae29 ("x86,objtool: Split UNWIND_HINT_EMPTY in
two") changed the ORC format. Although ORC is internal to the kernel,
it's the only way for external tools to get reliable kernel stack traces
on x86-64. In particular, the drgn debugger [1] uses ORC for stack
unwinding, and these format changes broke it [2]. As the drgn
maintainer, I don't care how often or how much the kernel changes the
ORC format as long as I have a way to detect the change.
It suffices to store a version identifier in the vmlinux and kernel
module ELF files (to use when parsing ORC sections from ELF), and in
kernel memory (to use when parsing ORC from a core dump+symbol table).
Rather than hard-coding a version number that needs to be manually
bumped, Peterz suggested hashing the definitions from orc_types.h. If
there is a format change that isn't caught by this, the hashing script
can be updated.
This patch adds an .orc_header allocated ELF section containing the
20-byte hash to vmlinux and kernel modules, along with the corresponding
__start_orc_header and __stop_orc_header symbols in vmlinux.

Reiji reports that the arm64 implementation of arch_perf_update_userpage()
is now ignored and replaced by the dummy stub in core code.
This seems to happen since the PMUv3 driver was moved to driver/perf.
As it turns out, dropping the __weak attribute from the *prototype*
of the function solves the problem. You're right, this doesn't seem
to make much sense. And yet... It appears that both symbols get
flagged as weak, and that the first one to appear in the link order
wins:
$ nm drivers/perf/arm_pmuv3.o|grep arch_perf_update_userpage
0000000000001db0 W arch_perf_update_userpage
Dropping the attribute from the prototype restores the expected
behaviour, and arm64 is able to enjoy arch_perf_update_userpage()
again.

The ${atomic}_dec_if_positive() ops are unlike all the other conditional
atomic ops. Rather than returning a boolean success value, these return
the value that the atomic variable would be updated to, even when no
update is performed.
We missed this when adding kerneldoc comments, and the documentation for
${atomic}_dec_if_positive() erroneously states:
| Return: @true if @v was updated, @false otherwise.
Ideally we'd clean this up by aligning ${atomic}_dec_if_positive() with
the usual atomic op conventions: with ${atomic}_fetch_dec_if_positive()
for those who care about the value of the varaible, and
${atomic}_dec_if_positive() returning a boolean success value.
In the mean time, align the documentation with the current reality.

So we can apply the tlv320aic3xxx DT conversion.

There is a class of interrupt controllers out there that, once they
have signalled a given interrupt number, will still signal incoming
instances of the *same* interrupt despite the original interrupt
not having been EOIed yet.
As long as the new interrupt reaches the *same* CPU, nothing bad
happens, as that CPU still has its interrupts globally disabled,
and we will only take the new interrupt once the interrupt has
been EOIed.
However, things become more "interesting" if an affinity change comes
in while the interrupt is being handled. More specifically, while
the per-irq lock is being dropped. This results in the affinity change
taking place immediately. At this point, there is nothing that prevents
the interrupt from firing on the new target CPU. We end-up with the
interrupt running concurrently on two CPUs, which isn't a good thing.
And that's where things become worse: the new CPU notices that the
interrupt handling is in progress (irq_may_run() return false), and
*drops the interrupt on the floor*.
The whole race looks like this:
CPU 0 | CPU 1
-----------------------------|-----------------------------
interrupt start |
handle_fasteoi_irq | set_affinity(CPU 1)
handler |
... | interrupt start
... | handle_fasteoi_irq -> early out
handle_fasteoi_irq return | interrupt end
interrupt end |
If the interrupt was an edge, too bad. The interrupt is lost, and
the system will eventually die one way or another. Not great.
A way to avoid this situation is to detect this problem at the point
we handle the interrupt on the new target. Instead of dropping the
interrupt, use the resend mechanism to force it to be replayed.
Also, in order to limit the impact of this workaround to the pathetic
architectures that require it, gate it behind a new irq flag aptly
named IRQD_RESEND_WHEN_IN_PROGRESS.

check_bugs() has become a dumping ground for all sorts of activities to
finalize the CPU initialization before running the rest of the init code.
Most are empty, a few do actual bug checks, some do alternative patching
and some cobble a CPU advertisement string together....
Aside of that the current implementation requires duplicated function
declaration and mostly empty header files for them.
Provide a new function arch_cpu_finalize_init(). Provide a generic
declaration if CONFIG_ARCH_HAS_CPU_FINALIZE_INIT is selected and a stub
inline otherwise.
This requires a temporary #ifdef in start_kernel() which will be removed
along with check_bugs() once the architectures are converted over.

Most of the ioctls to net protocols operates directly on userspace
argument (arg). Usually doing get_user()/put_user() directly in the
ioctl callback. This is not flexible, because it is hard to reuse these
functions without passing userspace buffers.
Change the "struct proto" ioctls to avoid touching userspace memory and
operate on kernel buffers, i.e., all protocol's ioctl callbacks is
adapted to operate on a kernel memory other than on userspace (so, no
more {put,get}_user() and friends being called in the ioctl callback).
This changes the "struct proto" ioctl format in the following way:
int (*ioctl)(struct sock *sk, int cmd,
- unsigned long arg);
+ int *karg);
(Important to say that this patch does not touch the "struct proto_ops"
protocols)
So, the "karg" argument, which is passed to the ioctl callback, is a
pointer allocated to kernel space memory (inside a function wrapper).
This buffer (karg) may contain input argument (copied from userspace in
a prep function) and it might return a value/buffer, which is copied
back to userspace if necessary. There is not one-size-fits-all format
(that is I am using 'may' above), but basically, there are three type of
ioctls:
1) Do not read from userspace, returns a result to userspace
2) Read an input parameter from userspace, and does not return anything
to userspace
3) Read an input from userspace, and return a buffer to userspace.
The default case (1) (where no input parameter is given, and an "int" is
returned to userspace) encompasses more than 90% of the cases, but there
are two other exceptions. Here is a list of exceptions:
* Protocol RAW:
* cmd = SIOCGETVIFCNT:
* input and output = struct sioc_vif_req
* cmd = SIOCGETSGCNT
* input and output = struct sioc_sg_req
* Explanation: for the SIOCGETVIFCNT case, userspace passes the input
argument, which is struct sioc_vif_req. Then the callback populates
the struct, which is copied back to userspace.
* Protocol RAW6:
* cmd = SIOCGETMIFCNT_IN6
* input and output = struct sioc_mif_req6
* cmd = SIOCGETSGCNT_IN6
* input and output = struct sioc_sg_req6
* Protocol PHONET:
* cmd == SIOCPNADDRESOURCE | SIOCPNDELRESOURCE
* input int (4 bytes)
* Nothing is copied back to userspace.
For the exception cases, functions sock_sk_ioctl_inout() will
copy the userspace input, and copy it back to kernel space.
The wrapper that prepare the buffer and put the buffer back to user is
sk_ioctl(), so, instead of calling sk->sk_prot->ioctl(), the callee now
calls sk_ioctl(), which will handle all cases.

Selftests excluded - we have 58 patches and diff of +442/-199, which
isn't really small but perhaps with the exception of the WiFi locking
change it's old(ish) bugs.
We have no known problems with v6.4.
The selftest changes are rather large as MPTCP folks try to apply
Greg's guidance that selftest from torvalds/linux should be able to
run against stable kernels.
Last thing I should call out is the DCCP/UDP-lite deprecation notices.
We are fairly sure those are dead, but if we're wrong reverting them
back in won't be fun.

"This is an unusually large bunch of bug fixes for the later rc cycle,
rxe and mlx5 both dumped a lot of things at once. rxe continues to fix
itself, and mlx5 is fixing a bunch of "queue counters" related bugs.
There is one highly notable bug fix regarding the qkey. This small
security check was missed in the original 2005 implementation and it
allows some significant issues.
Summary:
- Two rtrs bug fixes for error unwind bugs
- Several rxe bug fixes:
* Incorrect Rx packet validation
* Using memory without a refcount
* Syzkaller found use before initialization
* Regression fix for missing locking with the tasklet conversion
from this merge window
- Have bnxt report the correct link properties to userspace, this was
a regression in v6.3
- Several mlx5 bug fixes:
* Kernel crash triggerable by userspace for the RAW ethernet
profile
* Defend against steering refcounting issues created by userspace
* Incorrect change of QP port affinity parameters in some LAG
configurations
- Fix mlx5 Q counters:
* Do not over allocate Q counters to allow userspace to use the
full port capacity
* Kernel crash triggered by eswitch due to mis-use of Q counters
* Incorrect mlx5_device for Q counters in some LAG configurations
- Properly implement the IBA spec restricting privileged qkeys to
root
- Always an error when reading from a disassociated device's event
queue

[Why]
The sequence for collecting down_reply from source perspective should
be:
Request_n->repeat (get partial reply of Request_n->clear message ready
flag to ack DPRX that the message is received) till all partial
replies for Request_n are received->new Request_n+1.
Now there is chance that drm_dp_mst_hpd_irq() will fire new down
request in the tx queue when the down reply is incomplete. Source is
restricted to generate interveleaved message transactions so we should
avoid it.
Also, while assembling partial reply packets, reading out DPCD DOWN_REP
Sideband MSG buffer + clearing DOWN_REP_MSG_RDY flag should be
wrapped up as a complete operation for reading out a reply packet.
Kicking off a new request before clearing DOWN_REP_MSG_RDY flag might
be risky. e.g. If the reply of the new request has overwritten the
DPRX DOWN_REP Sideband MSG buffer before source writing one to clear
DOWN_REP_MSG_RDY flag, source then unintentionally flushes the reply
for the new request. Should handle the up request in the same way.
[How]
Separete drm_dp_mst_hpd_irq() into 2 steps. After acking the MST IRQ
event, driver calls drm_dp_mst_hpd_irq_send_new_request() and might
trigger drm_dp_mst_kick_tx() only when there is no on going message
transaction.
Changes since v1:
* Reworked on review comments received
-> Adjust the fix to let driver explicitly kick off new down request
when mst irq event is handled and acked
-> Adjust the commit message
Changes since v2:
* Adjust the commit message
* Adjust the naming of the divided 2 functions and add a new input
parameter "ack".
* Adjust code flow as per review comments.
Changes since v3:
* Update the function description of drm_dp_mst_hpd_irq_handle_event
Changes since v4:
* Change ack of drm_dp_mst_hpd_irq_handle_event() to be an array align
the size of esi[]

If fast_switch_possible flag is set by the scaling driver, the governor
is free to select fast_switch function even if adjust_perf is set. Some
scaling drivers which use adjust_perf don't set fast_switch thinking
that the governor would never fall back to fast_switch. But the governor
can fall back to fast_switch even in runtime if frequency invariance is
disabled due to some reason. This could crash the kernel if the driver
didn't set the fast_switch function pointer.
Therefore, fail driver registration if it has adjust_perf without
fast_switch.

The addition of might_sleep() to down_timeout() caused the latter to
enable interrupts unconditionally in some cases, which in turn broke
the ACPI S3 wakeup path in acpi_suspend_enter(), where down_timeout()
is called by acpi_disable_all_gpes() via acpi_ut_acquire_mutex().
Namely, if CONFIG_DEBUG_ATOMIC_SLEEP is set, might_sleep() causes
might_resched() to be used and if CONFIG_PREEMPT_VOLUNTARY is set,
this triggers __cond_resched() which may call preempt_schedule_common(),
so __schedule() gets invoked and it ends up with enabled interrupts (in
the prev == next case).
Now, enabling interrupts early in the S3 wakeup path causes the kernel
to crash.
Address this by modifying acpi_suspend_enter() to disable GPEs without
attempting to acquire the sleeping lock which is not needed in that code
path anyway.

Bump the minor version to declare event age tracking feature is now
available.
In kernel amdgpu driver, kfd_wait_on_events is used to support user
space signal event wait function. For multiple threads waiting on same
event scenery, race condition could occur since some threads after
checking signal condition, before calling kfd_wait_on_events, the
event interrupt could be fired and wake up other thread which are
sleeping on this event. Then those threads could fall into sleep
without waking up again. Adding event age tracking in both kernel and
user mode, will help avoiding this race condition.

* kvm-arm64/configurable-id-regs:
: Configurable ID register infrastructure, courtesy of Jing Zhang
:
: Create generalized infrastructure for allowing userspace to select the
: supported feature set for a VM, so long as the feature set is a subset
: of what hardware + KVM allows. This does not add any new features that
: are user-configurable, and instead focuses on the necessary refactoring
: to enable future work.
:
: As a consequence of the series, feature asymmetry is now deliberately
: disallowed for KVM. It is unlikely that VMMs ever configured VMs with
: asymmetry, nor does it align with the kernel's overall stance that
: features must be uniform across all cores in the system.
:
: Furthermore, KVM incorrectly advertised an IMP_DEF PMU to guests for
: some time. Migrations from affected kernels was supported by explicitly
: allowing such an ID register value from userspace, and forwarding that
: along to the guest. KVM now allows an IMP_DEF PMU version to be restored
: through the ID register interface, but reinterprets the user value as
: not implemented (0).
KVM: arm64: Rip out the vestiges of the 'old' ID register scheme

* kvm-arm64/ffa-proxy:
: pKVM FF-A Proxy, courtesy Will Deacon and Andrew Walbran
:
: From the cover letter:
:
: pKVM's primary goal is to protect guest pages from a compromised host by
: enforcing access control restrictions using stage-2 page-tables. Sadly,
: this cannot prevent TrustZone from accessing non-secure memory, and a
: compromised host could, for example, perform a 'confused deputy' attack
: by asking TrustZone to use pages that have been donated to protected
: guests. This would effectively allow the host to have TrustZone
: exfiltrate guest secrets on its behalf, hence breaking the isolation
: that pKVM intends to provide.
:
: This series addresses this problem by providing pKVM with the ability to
: monitor SMCs following the Arm FF-A protocol. FF-A provides (among other
: things) a set of memory management APIs allowing the Normal World to
: share, donate or lend pages with Secure. By monitoring these SMCs, pKVM
: can ensure that the pages that are shared, lent or donated to Secure by
: the host kernel are only pages that it owns.

* kvm-arm64/eager-page-splitting:
: Eager Page Splitting, courtesy of Ricardo Koller.
:
: Dirty logging performance is dominated by the cost of splitting
: hugepages to PTE granularity. On systems that mere mortals can get their
: hands on, each fault incurs the cost of a full break-before-make
: pattern, wherein the broadcast invalidation and ensuing serialization
: significantly increases fault latency.
:
: The goal of eager page splitting is to move the cost of hugepage
: splitting out of the stage-2 fault path and instead into the ioctls
: responsible for managing the dirty log:
:
: - If manual protection is enabled for the VM, hugepage splitting
: happens in the KVM_CLEAR_DIRTY_LOG ioctl. This is desirable as it
: provides userspace granular control over hugepage splitting.
:
: - Otherwise, if userspace relies on the legacy dirty log behavior
: (clear on collection), hugepage splitting is done at the moment dirty
: logging is enabled for a particular memslot.
:
: Support for eager page splitting requires explicit opt-in from
: userspace, which is realized through the
: KVM_CAP_ARM_EAGER_SPLIT_CHUNK_SIZE capability.

The data type of struct acpi_device_id is defined in the
mod_devicetable.h. It's suboptimal to require user with
the almost agnostic code to include acpi.h solely for the
macro that affects the data type defined elsewhere.
Taking into account the above and for the sake of consistency
move ACPI_DEVICE_CLASS() to mod_devicetable.h.
Note, that with CONFIG_ACPI=n the ID table will be filed with data
but it does not really matter because either it won't be used, or
won't be compiled in some cases (when guarded by respective ifdeffery).
