Make it impossible to enable support for the DES or DES3 Kerberos
encryption types in SunRPC. These enctypes were deprecated by RFCs
6649 and 8429 because they are known to be insecure.

This patch grants write delegations for OPEN with NFS4_SHARE_ACCESS_WRITE
if there is no conflict with other OPENs.
Write delegation conflicts with another OPEN, REMOVE, RENAME and SETATTR
are handled the same as read delegation using notify_change,
try_break_deleg.
The NFSv4.0 protocol does not enable a server to determine that a
conflicting GETATTR originated from the client holding the
delegation versus coming from some other client. With NFSv4.1 and
later, the SEQUENCE operation that begins each COMPOUND contains a
client ID, so delegation recall can be safely squelched in this case.
With NFSv4.0, however, the server must recall or send a CB_GETATTR
(per RFC 7530 Section 16.7.5) even when the GETATTR originates from
the client holding that delegation.
An NFSv4.0 client can trigger a pathological situation if it always
sends a DELEGRETURN preceded by a conflicting GETATTR in the same
COMPOUND. COMPOUND execution will always stop at the GETATTR and the
DELEGRETURN will never get executed. The server eventually revokes
the delegation, which can result in loss of open or lock state.
Tracepoint added to track whether read or write delegation is granted.

Replace the -1 (no limit) with a zero (no reserved space).
This prevents certain non-determinant client behavior, such as
silly-renaming a file when the only open reference is a write
delegation. Such a rename can leave unexpected .nfs files in a
directory that is otherwise supposed to be empty.
Note that other server implementations that support write delegation
also set this field to zero.

If the GETATTR request on a file that has write delegation in effect and
the request attributes include the change info and size attribute then
the write delegation is recalled. If the delegation is returned within
30ms then the GETATTR is serviced as normal otherwise the NFS4ERR_DELAY
error is returned for the GETATTR.
Add counter for write delegation recall due to conflict GETATTR. This is
used to evaluate the need to implement CB_GETATTR to adoid recalling the
delegation with conflit GETATTR.

Jeff confirmed his original fix addressed his pynfs test failure,
but this same bug also impacted qemu: accessing qcow2 virtual disks
using direct I/O was failing. Jeff's fix missed that you have to
shorten the bio_vec element by the same amount as you increased
the page offset.

Since commit 3d5089c4263d ("of/address: Add support for 3 address cell
bus"), the DT address functions can handle translating buses with 3
address cells. Replace the custom code with the for_each_of_range()
iterator.
The original code had fallbacks to get "#address-cells"/"#size-cells"
from the bus parent node if they are missing. This is non-standard
behavior, and AFAICT the upstream .dts files never relied on that.

The boost control currently applies to the whole system. However, users
may prefer to boost a subset of cores in order to provide prioritized
performance to workloads running on the boosted cores.
Enable per-policy boost by adding a 'boost' sysfs interface under each
policy path. This can be found at:
/sys/devices/system/cpu/cpufreq/policy<*>/boost
Same to the global boost switch, writing 1/0 to the per-policy 'boost'
enables/disables boost on a cpufreq policy respectively.
The user view of global and per-policy boost controls should be:
1. Enabling global boost initially enables boost on all policies, and
per-policy boost can then be enabled or disabled individually, given that
the platform does support so.
2. Disabling global boost makes the per-policy boost interface illegal.

Passing a struct thermal_trip pointer instead of a trip index to the
.get_trend() thermal zone callback allows one of its 2 implementations,
the thermal_get_trend() function in the ACPI thermal driver, to be
simplified quite a bit, and the other implementation of it in the
ti-soc-thermal driver does not even use the relevant callback argument.
For this reason, change the .get_trend() thermal zone callback
definition and adjust the related code accordingly.

After recent changes in the ACPI thermal driver and in the Intel DTS
IOSF thermal driver, all thermal zone drivers are expected to use trip
tables for initialization and none of them should implement
.get_trip_type(), .get_trip_temp() or .get_trip_hyst() callbacks, so
drop these callbacks entirely from the core.

pcc_cpufreq_target():
cpufreq_freq_transition_begin();
spin_lock(&pcc_lock);
[critical section]
cpufreq_freq_transition_end();
spin_unlock(&pcc_lock);
Above code has a performance issue, consider that Task0 executes
'cpufreq_freq_transition_end()' to wake Task1 and preempted imediatedly
without releasing 'pcc_lock', then Task1 needs to wait for Task0 to
release 'pcc_lock'. In the worst case, this locking order can result in
Task1 wasting two scheduling rounds before it can enter the critical
section.

The field 'transition_task' of policy structure is used to track the
task which is performing the frequency transition. Using this field to
print a warning once detect a case where the same task is calling
_begin() again before completing the preivous frequency transition via
the _end().
However, there is a potential race condition in _end() and _begin() APIs
while updating the field 'transition_task' of policy, the scenario is
depicted below:
Task A Task B
/* 1st freq transition */
Invoke _begin() {
...
...
}
/* 2nd freq transition */
Invoke _begin() {
... //waiting for A to
... //clear
... //transition_ongoing
... //in _end() for
... //the 1st transition
|
Change the frequency |
|
Invoke _end() { |
... |
... |
transition_ongoing = false; V
transition_ongoing = true;
transition_task = current;
transition_task = NULL;
... //A overwrites the task
... //performing the transition
... //result in error warning.
}
To fix this race condition, the transition_lock of policy structure is
now acquired before updating policy structure in _end() API. Which ensure
that only one task can update the 'transition_task' field at a time.

Merge ARM and related thermal control updates for 6.6-rc1 from Daniel
Lezcano:
"- Check if the Tegra BPMP supports the trip points in order to set the
.set_trips callback (Mikko Perttunen)
- Add the new Loongson-2 thermal sensor along with the DT bindings
(Yinbo Zhu)
- Use IS_ERR_OR_NULL helper to replace a double test on the TI bandgap
sensor (Li Zetao)
- Remove the call to platform_set_drvdata() as there is no call to
platform_get_drvdata() in a bunch of drivers where that happens
(Andrei Coardos)
- Switch the Mediatek LVTS mode to filtered in order to enable the
interrupts (Nícolas F. R. A. Prado)
- Fix Wvoid-pointer-to-enum-cast warning on the Exynos TMU (Krzysztof
Kozlowski)
- Remove redundant usage of of_match_ptr() as the driver db8500
already depends on CONFIG_OF (Ruan Jinjie)
- Remove redundant dev_err_probe() because the underlying function
already called it in the Mediatek sensor (Chen Jiahao)
- Free calibration nvmem after reading it on sun8i (Mark Brown)
- Remove useless comment in the code on sun8i (Yangtao Li)
- Make tsens_xxxx_nvmem static to fix sparse warning on QCom tsens (Min-Hua Chen)
- Remove error message at probe deferral on imx8mm (Ahmad Fatoum)

LVTS (Minjie Du)

However, continuous physical memory does not seem to be required in
module_zstd_decompress(), so use vmalloc() instead, to prevent the
warning and avoid potential failures at loading compressed modules.

- Full support for dynamic allocations, following the temporary
bodges that were done as fixes in the previous release.
