sched/uclamp: Make select_idle_capacity() use util_fits_cpu()

Use the new util_fits_cpu() to ensure migration margin and capacity
pressure are taken into account correctly when uclamp is being used
otherwise we will fail to consider CPUs as fitting in scenarios where
they should.

sched/uclamp: Fix relationship between uclamp and migration margin

[ Upstream commit 48d5e9daa8b767e75ed9421665b037a49ce4bc04 ]

fits_capacity() verifies that a util is within 20% margin of the
capacity of a CPU, which is an attempt to speed up upmigration.

But when uclamp is used, this 20% margin is problematic because for
example if a task is boosted to 1024, then it will not fit on any CPU
according to fits_capacity() logic.

Or if a task is boosted to capacity_orig_of(medium_cpu). The task will
end up on big instead on the desired medium CPU.

Similar corner cases exist for uclamp and usage of capacity_of().
Slightest irq pressure on biggest CPU for example will make a 1024
boosted task look like it can't fit.

What we really want is for uclamp comparisons to ignore the migration
margin and capacity pressure, yet retain them for when checking the
_actual_ util signal.

For example, task p:

p->util_avg = 300
p->uclamp[UCLAMP_MIN] = 1024

Will fit a big CPU. But

p->util_avg = 900
p->uclamp[UCLAMP_MIN] = 1024

will not, this should trigger overutilized state because the big CPU is
now *actually* being saturated.

Similar reasoning applies to capping tasks with UCLAMP_MAX. For example:

p->util_avg = 1024
p->uclamp[UCLAMP_MAX] = capacity_orig_of(medium_cpu)

Should fit the task on medium cpus without triggering overutilized
state.

Inlined comments expand more on desired behavior in more scenarios.

Introduce new util_fits_cpu() function which encapsulates the new logic.
The new function is not used anywhere yet, but will be used to update
various users of fits_capacity() in later patches.

ovl: use ovl_copy_{real,upper}attr() wrappers

[ Upstream commit 2878dffc7db0b5a51e308ccb6b571296b57c82e7 ]

When copying inode attributes from the upper or lower layer to ovl inodes
we need to take the upper or lower layer's mount's idmapping into
account. In a lot of places we call ovl_copyattr() only on upper inodes and
in some we call it on either upper or lower inodes. Split this into two
separate helpers.

The first one should only be called on upper
inodes and is thus called ovl_copy_upperattr(). The second one can be
called on upper or lower inodes. We add ovl_copy_realattr() for this
task. The new helper makes use of the previously added ovl_i_path_real()
helper. This is needed to support idmapped base layers with overlay.

When overlay copies the inode information from an upper or lower layer
to the relevant overlay inode it will apply the idmapping of the upper
or lower layer when doing so. The ovl inode ownership will thus always
correctly reflect the ownership of the idmapped upper or lower layer.

All idmapping helpers are nops when no idmapped base layers are used.

During early boot, memblock reserves the pages for the ramoops reserved
memory node in DT that would otherwise be part of the direct lowmem
mapping. Pstore's ram backend reuses those reserved pages to change the
memory type (writeback or non-cached) by passing the pages to vmap()
(see pfn_to_page() usage in persistent_ram_vmap() for more details) with
specific flags. When read_kcore() starts iterating over the vmalloc
region, it runs over the virtual address that vmap() returned for
ramoops. In aligned_vread() the virtual address is passed to
vmalloc_to_page() which returns the page struct for the reserved lowmem
area. That lowmem page is passed to kmap_atomic(), which effectively
calls page_to_virt() that assumes a lowmem page struct must be directly
accessible with __va() and friends. These pages are mapped via vmap()
though, and the lowmem mapping was never made, so accessing them via the
lowmem virtual address oopses like above.

Let's side-step this problem by passing VM_IOREMAP to vmap(). This will
tell vread() to not include the ramoops region in the kcore. Instead the
area will look like a bunch of zeros. The alternative is to teach kmap()
about vmalloc areas that intersect with lowmem. Presumably such a change
isn't a one-liner, and there isn't much interest in inspecting the
ramoops region in kcore files anyway, so the most expedient route is
taken for now.

seccomp: Move copy_seccomp() to no failure path.

[ Upstream commit a1140cb215fa13dcec06d12ba0c3ee105633b7c4 ]

Our syzbot instance reported memory leaks in do_seccomp() [0], similar
to the report [1].  It shows that we miss freeing struct seccomp_filter
and some objects included in it.

We can reproduce the issue with the program below [2] which calls one
seccomp() and two clone() syscalls.

The first clone()d child exits earlier than its parent and sends a
signal to kill it during the second clone(), more precisely before the
fatal_signal_pending() test in copy_process().  When the parent receives
the signal, it has to destroy the embryonic process and return -EINTR to
user space.  In the failure path, we have to call seccomp_filter_release()
to decrement the filter's refcount.

Initially, we called it in free_task() called from the failure path, but
the commit 3a15fb6ed92c ("seccomp: release filter after task is fully
dead") moved it to release_task() to notify user space as early as possible
that the filter is no longer used.

To keep the change and current seccomp refcount semantics, let's move
copy_seccomp() just after the signal check and add a WARN_ON_ONCE() in
free_task() for future debugging.

arm64: mm: kfence: only handle translation faults

[ Upstream commit 0bb1fbffc631064db567ccaeb9ed6b6df6342b66 ]

Alexander noted that KFENCE only expects to handle faults from invalid page
table entries (i.e. translation faults), but arm64's fault handling logic will
call kfence_handle_page_fault() for other types of faults, including alignment
faults caused by unaligned atomics. This has the unfortunate property of
causing those other faults to be reported as "KFENCE: use-after-free",
which is misleading and hinders debugging.

Fix this by only forwarding unhandled translation faults to the KFENCE
code, similar to what x86 does already.

Alexander has verified that this passes all the tests in the KFENCE test
suite and avoids bogus reports on misaligned atomics.

arm64: Treat ESR_ELx as a 64-bit register

[ Upstream commit 8d56e5c5a99ce1d17d39ce5a8260e42c2a2d7682 ]

In the initial release of the ARM Architecture Reference Manual for
ARMv8-A, the ESR_ELx registers were defined as 32-bit registers. This
changed in 2018 with version D.a (ARM DDI 0487D.a) of the architecture,
when they became 64-bit registers, with bits [63:32] defined as RES0. In
version G.a, a new field was added to ESR_ELx, ISS2, which covers bits
[36:32].  This field is used when the Armv8.7 extension FEAT_LS64 is
implemented.

As a result of the evolution of the register width, Linux stores it as
both a 64-bit value and a 32-bit value, which hasn't affected correctness
so far as Linux only uses the lower 32 bits of the register.

Make the register type consistent and always treat it as 64-bit wide. The
register is redefined as an "unsigned long", which is an unsigned
double-word (64-bit quantity) for the LP64 machine (aapcs64 [1], Table 1,
page 14). The type was chosen because "unsigned int" is the most frequent
type for ESR_ELx and because FAR_ELx, which is used together with ESR_ELx
in exception handling, is also declared as "unsigned long". The 64-bit type
also makes adding support for architectural features that use fields above
bit 31 easier in the future.

The KVM hypervisor will receive a similar update in a subsequent patch.

[ Upstream commit 99139b80c1b3d73026ed8be2de42c52e2976ab64 ]

APR and other packet routers like GPR are pretty much same and
interact with other drivers in similar way.

Ex: GPR ports can be considered as APR services, only difference
is they are allocated dynamically.

Other difference is packet layout, which should not matter
with the apis abstracted. Apart from this the rest of the
functionality is pretty much identical across APR and GPR.

Make the apr code more reusable by abstracting it service level,
rather than device level so that we do not need to write
new drivers for other new packet routers like GPR.

This patch is in preparation to add GPR support to this driver.

Commit 60a05ed059a0 ("arm64: dts: qcom: msm8916: Add MSM8916-specific
compatibles to SCM/MSS") updated the MSM8916 device tree to make use of
the new compatible but still kept the old "qcom,q6v5-pil" as fallback.

This is inconsistent with other SoCs and conflicts with the description
in the binding documentation (which says that only one compatible should
be present). Also, it has no functional advantage since older kernels
could not handle this DT anyway (e.g. "power-domains" in the MSS node is
only supported by kernels that also support "qcom,msm8916-mss-pil").

Make this consistent with other SoCs by using only the
"qcom,msm8916-mss-pil" compatible.

Qualcomm MSM8996 Pro is a variant of MSM8996 with higher frequencies
supported both on CPU and GPU. There are other minor hardware
differencies in the CPU and GPU regulators and bus fabrics.

However this results in significant differences between 8996 and 8996
Pro CPU OPP tables. Judging from msm-3.18 there are only few common
frequencies supported by both msm8996 and msm8996pro. Rather than
hacking the tables for msm8996, split msm8996pro support into a separate
file. Later this would allow having additional customizations for the
CBF, CPR, retulators, etc.

The issue it fixes is a ~20s boot time delay when booting from S5. It

not supported. Make sure to handle the case where the current speed is
B0 (hangup) without dividing by zero when determining the clock source.

When extending file within last block it can happen that the extent is
already rounded to the blocksize and thus contains the offset we want to
grow up to. In such case we would mistakenly expand the last extent and
make it one block longer than it should be, exposing unallocated block
in a file and causing data corruption. Fix the problem by properly

When extending file with a hole, we tried to preserve existing

net: fec: properly guard irq coalesce setup

commit 7e6303567ce3ca506e4a2704e4baa86f1d8bde02 upstream.

Prior to the Fixes: commit, the initialization code went through the
same fec_enet_set_coalesce() function as used by ethtool, and that
function correctly checks whether the current variant has support for
irq coalescing.

Now that the initialization code instead calls fec_enet_itr_coal_set()
directly, that call needs to be guarded by a check for the
FEC_QUIRK_HAS_COALESCE bit.

perf: Fix perf_pending_task() UaF

[ Upstream commit 517e6a301f34613bff24a8e35b5455884f2d83d8 ]

Per syzbot it is possible for perf_pending_task() to run after the
event is free()'d. There are two related but distinct cases:

 - the task_work was already queued before destroying the event;
 - destroying the event itself queues the task_work.

The first cannot be solved using task_work_cancel() since
perf_release() itself might be called from a task_work (____fput),
which means the current->task_works list is already empty and
task_work_cancel() won't be able to find the perf_pending_task()
entry.

The simplest alternative is extending the perf_event lifetime to cover
the task_work.

The second is just silly, queueing a task_work while you know the
event is going away makes no sense and is easily avoided by
re-arranging how the event is marked STATE_DEAD and ensuring it goes
through STATE_OFF on the way down.

[ Upstream commit df727d4547de568302b0ed15b0d4e8a469bdb456 ]

Currently, when a FEC device is brought up, the irq coalesce settings
are reset to their default values (1000us, 200 frames). That's
unexpected, and breaks for example use of an appropriate .link file to
make systemd-udev apply the desired
settings (https://www.freedesktop.org/software/systemd/man/systemd.link.html),
or any other method that would do a one-time setup during early boot.

Refactor the code so that fec_restart() instead uses
fec_enet_itr_coal_set(), which simply applies the settings that are
stored in the private data, and initialize that private data with the

Microchip USB Analyzer can activate the internal termination resistors
by setting the "termination" option ON, or OFF to to deactivate them.
As I've observed, both with my oscilloscope and captured USB packets
below, you must send "0" to turn it ON, and "1" to turn it OFF.

From the schematics in the user's guide, I can confirm that you must
drive the CAN_RES signal LOW "0" to activate the resistors.

Reverse the argument value of usb_msg.termination to fix this.

These are the two commands sequence, ON then OFF.

libbpf: Use page size as max_entries when probing ring buffer map

[ Upstream commit 689eb2f1ba46b4b02195ac2a71c55b96d619ebf8 ]

Using page size as max_entries when probing ring buffer map, else the
probe may fail on host with 64KB page size (e.g., an ARM64 host).

After the fix, the output of "bpftool feature" on above host will be
correct.

The bounds checks in snd_soc_put_volsw_sx() are only being applied to the
first channel, meaning it is possible to write out of bounds values to the
second channel in stereo controls. Add appropriate checks.

There may be failure when start 1 channel recording after
8 channels recording. The reason is that the CHnF
flags are not cleared successfully by software reset.

This issue is triggerred by the change of clearing

CHnF flags are write 1 clear bits. Clear them by force

nfp: fix use-after-free in area_cache_get()

commit 02e1a114fdb71e59ee6770294166c30d437bf86a upstream.

area_cache_get() is used to distribute cache->area and set cache->id,
 and if cache->id is not 0 and cache->area->kref refcount is 0, it will
 release the cache->area by nfp_cpp_area_release(). area_cache_get()
 set cache->id before cpp->op->area_init() and nfp_cpp_area_acquire().

But if area_init() or nfp_cpp_area_acquire() fails, the cache->id is
 is already set but the refcount is not increased as expected. At this
 time, calling the nfp_cpp_area_release() will cause use-after-free.

To avoid the use-after-free, set cache->id after area_init() and
 nfp_cpp_area_acquire() complete successfully.

Note: This vulnerability is triggerable by providing emulated device
 equipped with specified configuration.
