[ Upstream commit 9fad9d560af5c654bb38e0b07ee54a4e9acdc5cd ]
Running syzkaller with the newly reintroduced signed integer overflow
sanitizer produces this report:

Historically, the signed integer overflow sanitizer did not work in the
kernel due to its interaction with `-fwrapv` but this has since been
changed [1] in the newest version of Clang. It was re-enabled in the kernel
with Commit 557f8c582a9b ("ubsan: Reintroduce signed overflow sanitizer").
Firstly, let's change the type of "speed" to unsigned long as
sr_select_speed()'s only caller passes in an unsigned long anyways.
$ git grep '\.select_speed'
| drivers/scsi/sr.c: .select_speed = sr_select_speed,
...
| static int cdrom_ioctl_select_speed(struct cdrom_device_info *cdi,
| unsigned long arg)
| {
| ...
| return cdi->ops->select_speed(cdi, arg);
| }
Next, let's add an extra check to make sure we don't exceed 0xffff/177
(350) since 0xffff is the max speed. This has two benefits: 1) we deal
with integer overflow before it happens and 2) we properly respect the
max speed of 0xffff. There are some "magic" numbers here but I did not
want to change more than what was necessary.

commit e227c11179dfb6970360c95a8d7b007eb3b223d6 upstream.
This reverts commit f0f99f371822c48847e02e56d6e7de507e18f186.
QDU1000 has 7 register regions. The earlier commit 8e2506d01231
("dt-bindings: cache: qcom,llcc: Add LLCC compatible for QDU1000/QRU1000")
to add llcc compatible was reflecting the same, but dtsi change for
QDU1000 was not aligning with its binding. Later, commit f0f99f371822
("dt-bindings: cache: qcom,llcc: correct QDU1000 reg entries") was merged
intended to fix this misalignment.
After the LLCC driver refactor, each LLCC bank/channel need to be
represented as one register space to avoid mapping to the region where
access is not there. Hence, revert the commit f0f99f371822 ("dt-bindings:
cache: qcom,llcc: correct QDU1000 reg entries") to align QDU1000 llcc
binding with its dtsi node.

If you try to set /proc/fs/cifs/SecurityFlags to 1 it
will set them to CIFSSEC_MUST_NTLMV2 which no longer is
relevant (the less secure ones like lanman have been removed
from cifs.ko) and is also missing some flags (like for
signing and encryption) and can even cause mount to fail,
so change this to set it to Kerberos in this case.
Also change the description of the SecurityFlags to remove mention
of flags which are no longer supported.

commit 3a5a8d343e1cf96eb9971b17cbd4b832ab19b8e7 upstream.
__split_huge_pmd_locked() can be called for a present THP, devmap or
(non-present) migration entry. It calls pmdp_invalidate() unconditionally
on the pmdp and only determines if it is present or not based on the
returned old pmd. This is a problem for the migration entry case because
pmd_mkinvalid(), called by pmdp_invalidate() must only be called for a
present pmd.
On arm64 at least, pmd_mkinvalid() will mark the pmd such that any future
call to pmd_present() will return true. And therefore any lockless
pgtable walker could see the migration entry pmd in this state and start
interpretting the fields as if it were present, leading to BadThings (TM).
GUP-fast appears to be one such lockless pgtable walker.
x86 does not suffer the above problem, but instead pmd_mkinvalid() will
corrupt the offset field of the swap entry within the swap pte. See link
below for discussion of that problem.
Fix all of this by only calling pmdp_invalidate() for a present pmd. And
for good measure let's add a warning to all implementations of
pmdp_invalidate[_ad](). I've manually reviewed all other
pmdp_invalidate[_ad]() call sites and believe all others to be conformant.
This is a theoretical bug found during code review. I don't have any test
case to trigger it in practice.

The current implementation of the fpga region assumes that the low-level
module registers a driver for the parent device and uses its owner pointer
to take the module's refcount. This approach is problematic since it can
lead to a null pointer dereference while attempting to get the region
during programming if the parent device does not have a driver.
To address this problem, add a module owner pointer to the fpga_region
struct and use it to take the module's refcount. Modify the functions for
registering a region to take an additional owner module parameter and
rename them to avoid conflicts. Use the old function names for helper
macros that automatically set the module that registers the region as the
owner. This ensures compatibility with existing low-level control modules
and reduces the chances of registering a region without setting the owner.
Also, update the documentation to keep it consistent with the new interface
for registering an fpga region.

commit da2a061888883e067e8e649d086df35c92c760a7 upstream.
The example usage of DAMOS filter sysfs files, specifically the part of
'matching' file writing for memcg type filter, is wrong. The intention is
to exclude pages of a memcg that already getting enough care from a given
scheme, but the example is setting the filter to apply the scheme to only
the pages of the memcg. Fix it.

commit 8af2d1ab78f2342f8c4c3740ca02d86f0ebfac5a upstream.
sched_core_share_pid() copies the cookie to userspace with
put_user(id, (u64 __user *)uaddr), expecting 64 bits of space.
The "unsigned long" datatype that is documented in core-scheduling.rst
however is only 32 bits large on 32 bit architectures.
Document "unsigned long long" as the correct data type that is always
64bits large.
This matches what the selftest cs_prctl_test.c has been doing all along.

Several clocks as well as both sgmiisys phandles were added by mistake
to the Ethernet bindings for MT7988. Also, the total number of clocks
didn't match with the actual number of items listed.
This happened because the vendor driver which served as a reference uses
a high number of syscon phandles to access various parts of the SoC
which wasn't acceptable upstream. Hence several parts which have never
previously been supported (such SerDes PHY and USXGMII PCS) are going to
be implemented by separate drivers. As a result the device tree will
look much more sane.
Quickly align the bindings with the upcoming reality of the drivers
actually adding support for the remaining Ethernet-related features of
the MT7988 SoC.

Previously we claimed "pcie_aspm=off" meant that ASPM would be disabled,
which is wrong.
Correct this to say that with "pcie_aspm=off", Linux doesn't touch any ASPM
configuration at all. ASPM may have been enabled by firmware, and that
will be left unchanged. See "aspm_support_enabled".

Two doc update patches and the following three fixes:
- On single node systems, the default pool is used but the node_nr_active
for the default pool was set to min_active. This effectively limited the
max concurrency of unbound pools on single node systems to 8 causing
performance regressions on some workloads. Fixed by setting the default
pool's node_nr_active to max_active.
- wq_update_node_max_active() could trigger divide-by-zero if the
intersection between the allowed CPUs for an unbound workqueue and online
CPUs becomes empty.
- When kick_pool() was trying to repatriate a worker to a CPU in its pod by
setting task->wake_cpu, it didn't consider whether the CPU being selected
is online or not which obviously can lead to subobtimal behaviors. On
s390, this triggered a crash in arch code. The workqueue patch removes the
gross misbehavior but doesn't fix the crash completely as there's a race
window in which CPUs can go down after wake_cpu is set. Need to decide
whether the fix should be on the core or arch side.

x86/CPU/AMD: Add models 0x10-0x1f to the Zen5 range
x86/sev: Check for MWAITX and MONITORX opcodes in the #VC handler
Documentation/timers/no_hz.rst states that the "nohz_full=" mask must not
include the boot CPU, which is no longer true after:
08ae95f4fd3b ("nohz_full: Allow the boot CPU to be nohz_full").
However after:
aae17ebb53cd ("workqueue: Avoid using isolated cpus' timers on queue_delayed_work")
the kernel will crash at boot time in this case; housekeeping_any_cpu()
returns an invalid CPU number until smp_init() brings the first
housekeeping CPU up.
Change housekeeping_any_cpu() to check the result of cpumask_any_and() and
return smp_processor_id() in this case.
This is just the simple and backportable workaround which fixes the
symptom, but smp_processor_id() at boot time should be safe at least for
type == HK_TYPE_TIMER, this more or less matches the tick_do_timer_boot_cpu
logic.
There is no worry about cpu_down(); tick_nohz_cpu_down() will not allow to
offline tick_do_timer_cpu (the 1st online housekeeping CPU).

There are a lot of minor DT fixes for Mediatek, Rockchip, Qualcomm and
Microchip and NXP, addressing both build-time warnings and bugs found during
runtime testing. Most of these changes are machine specific fixups, but
there are a few notable regressions that affect an entire SoC:
- The Qualcomm MSI support that was improved for 6.9 ended up being
wrong on some chips and now gets fixed.
- The i.MX8MP camera interface broke due to a typo and gets
updated again.
The main driver fix is also for Qualcomm platofrms, rewriting an interface
in the QSEECOM firmware support that could lead to crashing the kernel
from a trusted application. The only other code changes are minor fixes
for Mediatek SoC drivers.

- move the nvmem registration after the test one-byte read to improve the
situation with a race condition in nvmem
- fix the DT schema for ST M24C64-D
Explicitly disallow enabling mitigations at runtime for kernels that were
built with CONFIG_CPU_MITIGATIONS=n, as some architectures may omit code
entirely if mitigations are disabled at compile time.
E.g. on x86, a large pile of Kconfigs are buried behind CPU_MITIGATIONS,
and trying to provide sane behavior for retroactively enabling mitigations
is extremely difficult, bordering on impossible. E.g. page table isolation
and call depth tracking require build-time support, BHI mitigations will
still be off without additional kernel parameters, etc.

IIO: 1st set of fixes for the 6.9 cycle.
adi,asdis16475
- Write the correct field in the register when setting the sync mode.
bosch,bmp280
- Wrong chip specific data being used for the bme280 in the SPI driver.
- Fix that we can't use chip IDs because Bosch reuses them for incompatible
devices (some require a padding byte, others don't).
maxim,max30102 (dt binding)
- Fix incorrect property check to actually match on a device from the
binding rather than a completely different one due to a typo.
memsic,mxc4005
- Fix wrong masking of interrupt register accidentally disabling temperature
compensation. Also hammer initial state to 0 as it's not documented
if interrupts are masked after reset.
- Explicit reset on probe() and resume() as some devices do not power up
correctly without a reset.
