0685efd984 selftests/x86/iopl: Adjust to the faked iopl CLI/STI usage 
commit a72fdfd21e upstream.

Commit in Fixes changed the iopl emulation to not #GP on CLI and STI
because it would break some insane luserspace tools which would toggle
interrupts.

The corresponding selftest would rely on the fact that executing CLI/STI
would trigger a #GP and thus detect it this way but since that #GP is
not happening anymore, the detection is now wrong too.

Extend the test to actually look at the IF flag and whether executing
those insns had any effect on it. The STI detection needs to have the
fact that interrupts were previously disabled, passed in so do that from
the previous CLI test, i.e., STI test needs to follow a previous CLI one
for it to make sense.

6a315471cb thermal: Fix NULL pointer dereferences in of_thermal_ functions 
commit 96cfe05051 upstream.

of_parse_thermal_zones() parses the thermal-zones node and registers a
thermal_zone device for each subnode. However, if a thermal zone is
consuming a thermal sensor and that thermal sensor device hasn't probed
yet, an attempt to set trip_point_*_temp for that thermal zone device
can cause a NULL pointer dereference. Fix it.

bd40513d0b perf/core: Avoid put_page() when GUP fails 
commit 4716023a8f upstream.

PEBS PERF_SAMPLE_PHYS_ADDR events use perf_virt_to_phys() to convert PMU
sampled virtual addresses to physical using get_user_page_fast_only()
and page_to_phys().

Some get_user_page_fast_only() error cases return false, indicating no
page reference, but still initialize the output page pointer with an
unreferenced page. In these error cases perf_virt_to_phys() calls
put_page(). This causes page reference count underflow, which can lead
to unintentional page sharing.

Fix perf_virt_to_phys() to only put_page() if get_user_page_fast_only()
returns a referenced page.

df58fb431a scripts/lld-version.sh: Rewrite based on upstream ld-version.sh 
This patch is for linux-5.10.y only.

When scripts/lld-version.sh was initially written, it did not account
for the LLD_VENDOR cmake flag, which changes the output of ld.lld's
--version flag slightly.

Without LLD_VENDOR:

$ ld.lld --version
LLD 14.0.0 (compatible with GNU linkers)

With LLD_VENDOR:

$ ld.lld --version
Debian LLD 14.0.0 (compatible with GNU linkers)

As a result, CONFIG_LLD_VERSION is messed up and configuration values
that are dependent on it cannot be selected:

scripts/lld-version.sh: 20: printf: LLD: expected numeric value
scripts/lld-version.sh: 20: printf: LLD: expected numeric value
scripts/lld-version.sh: 20: printf: LLD: expected numeric value
init/Kconfig:52:warning: 'LLD_VERSION': number is invalid
.config:11:warning: symbol value '00000' invalid for LLD_VERSION
.config:8800:warning: override: CPU_BIG_ENDIAN changes choice state

This was fixed upstream by commit 1f09af0625 ("kbuild: Fix
ld-version.sh script if LLD was built with LLD_VENDOR") in 5.12 but that
was done to ld-version.sh after it was massively rewritten in
commit 02aff85922 ("kbuild: check the minimum linker version in
Kconfig").

To avoid bringing in that change plus its prerequisites and fixes, just
modify lld-version.sh to make it similar to the upstream ld-version.sh,
which handles ld.lld with or without LLD_VENDOR and ld.bfd without any
errors.

be3f603583 erofs: fix unsafe pagevec reuse of hooked pclusters 
commit 86432a6dca upstream.

There are pclusters in runtime marked with Z_EROFS_PCLUSTER_TAIL
before actual I/O submission. Thus, the decompression chain can be
extended if the following pcluster chain hooks such tail pcluster.

As the related comment mentioned, if some page is made of a hooked
pcluster and another followed pcluster, it can be reused for in-place
I/O (since I/O should be submitted anyway):
 _______________________________________________________________
|  tail (partial) page |          head (partial) page           |
|_____PRIMARY_HOOKED___|____________PRIMARY_FOLLOWED____________|

However, it's by no means safe to reuse as pagevec since if such
PRIMARY_HOOKED pclusters finally move into bypass chain without I/O
submission. It's somewhat hard to reproduce with LZ4 and I just found
it (general protection fault) by ro_fsstressing a LZMA image for long
time.

I'm going to actively clean up related code together with multi-page
folio adaption in the next few months. Let's address it directly for
easier backporting for now.

It appears that some devices are lying about their mask capability,
pretending that they don't have it, while they actually do.

endpoint.

Add a new per-device flag to deal with this. Further patches will

c49bfdfe53 parisc/entry: fix trace test in syscall exit path 
commit 3ec18fc783 upstream.

commit 8779e05ba8 ("parisc: Fix ptrace check on syscall return")
fixed testing of TI_FLAGS. This uncovered a bug in the test mask.
syscall_restore_rfi is only used when the kernel needs to exit to
usespace with single or block stepping and the recovery counter
enabled. The test however used _TIF_SYSCALL_TRACE_MASK, which
includes a lot of bits that shouldn't be tested here.

Fix this by using TIF_SINGLESTEP and TIF_BLOCKSTEP directly.

I encountered this bug by enabling syscall tracepoints. Both in qemu and
on real hardware. As soon as i enabled the tracepoint (sys_exit_read,
but i guess it doesn't really matter which one), i got random page
faults in userspace almost immediately.

b31bac0619 x86/iopl: Fake iopl(3) CLI/STI usage 
commit b968e84b50 upstream.

Since commit c8137ace56 ("x86/iopl: Restrict iopl() permission
scope") it's possible to emulate iopl(3) using ioperm(), except for
the CLI/STI usage.

Userspace CLI/STI usage is very dubious (read broken), since any
exception taken during that window can lead to rescheduling anyway (or
worse). The IOPL(2) manpage even states that usage of CLI/STI is highly
discouraged and might even crash the system.

Of course, that won't stop people and HP has the dubious honour of
being the first vendor to be found using this in their hp-health
package.

In order to enable this 'software' to still 'work', have the #GP treat
the CLI/STI instructions as NOPs when iopl(3). Warn the user that
their program is doing dubious things.

a0958a5354 net: stmmac: dwmac-rk: fix unbalanced pm_runtime_enable warnings 
commit 2d26f6e39a upstream.

This reverts commit 2c896fb02e
"net: stmmac: dwmac-rk: add pd_gmac support for rk3399" and fixes
unbalanced pm_runtime_enable warnings.

In the commit to be reverted, support for power management was
introduced to the Rockchip glue code. Later, power management support
was introduced to the stmmac core code, resulting in multiple
invocations of pm_runtime_{enable,disable,get_sync,put_sync}.

The multiple invocations happen in rk_gmac_powerup and
stmmac_{dvr_probe, resume} as well as in rk_gmac_powerdown and
stmmac_{dvr_remove, suspend}, respectively, which are always called
in conjunction.

3afe11be64 net: stmmac: add clocks management for gmac driver 
commit 5ec5582343 upstream.

This patch intends to add clocks management for stmmac driver:

If CONFIG_PM enabled:
1. Keep clocks disabled after driver probed.
2. Enable clocks when up the net device, and disable clocks when down
the net device.

If CONFIG_PM disabled:
Keep clocks always enabled after driver probed.

Note:
1. It is fine for ethtool, since the way of implementing ethtool_ops::begin
in stmmac is only can be accessed when interface is enabled, so the clocks
are ticked.
2. The MDIO bus has a different life cycle to the MAC, need ensure
clocks are enabled when _mdio_read/write() need clocks, because these
functions can be called while the interface it not opened.

Stable backport notes:
When run below command to remove ethernet driver on
stratix10 platform, there will be warning trace as below:

$ cd /sys/class/net/eth0/device/driver/
$ echo ff800000.ethernet > unbind

This issue is introduced by introducing upstream commit 8f269102ba
("net: stmmac: disable clocks in stmmac_remove_config_dt()")

But in latest mainline kernel, there is no this issue. Because this
patch improved clocks management for stmmac driver.
Therefore, backport it and its fixing patches to stable kernel v5.10.

eaafc59005 fortify: Explicitly disable Clang support 
commit a52f8a59ae upstream.

Clang has never correctly compiled the FORTIFY_SOURCE defenses due to
a couple bugs:

	Eliding inlines with matching __builtin_* names
	https://bugs.llvm.org/show_bug.cgi?id=50322

	Incorrect __builtin_constant_p() of some globals
	https://bugs.llvm.org/show_bug.cgi?id=41459

In the process of making improvements to the FORTIFY_SOURCE defenses, the
first (silent) bug (coincidentally) becomes worked around, but exposes
the latter which breaks the build. As such, Clang must not be used with
CONFIG_FORTIFY_SOURCE until at least latter bug is fixed (in Clang 13),
and the fortify routines have been rearranged.

Update the Kconfig to reflect the reality of the current situation.

a0199cf0c0 UPSTREAM: tracing/histogram: Fix UAF in destroy_hist_field() 
Calling destroy_hist_field() on an expression will recursively free
any operands associated with the expression. If during expression
parsing the operands of the expression are already set when an error
is encountered, there is no need to explicity free the operands. Doing
so will result in destroy_hist_field() being called twice for the
operands and lead to a use-after-free (UAF) error.

If the operands are associated with the expression, only call
destroy_hist_field() on the expression since the operands will be
recursively freed.

45490bfa1e x86/sev: Make the #VC exception stacks part of the default stacks storage 
commit 541ac97186 upstream.

The size of the exception stacks was increased by the commit in Fixes,
resulting in stack sizes greater than a page in size. The #VC exception
handling was only mapping the first (bottom) page, resulting in an
SEV-ES guest failing to boot.

Make the #VC exception stacks part of the default exception stacks
storage and allocate them with a CONFIG_AMD_MEM_ENCRYPT=y .config. Map
them only when a SEV-ES guest has been detected.

Rip out the custom VC stacks mapping and storage code.

In preparation for other confidential computing technologies, introduce

check for specific active confidential computing attributes, like
memory encryption. This is intended to eliminate having to add multiple
technology-specific checks to the code (e.g. if (sev_active() ||
tdx_active() || ... ).

commit a20eac0af0 upstream.

Previous fix aded bpf_clamp_umax() helper use to re-validate boundaries.
While that works correctly, it introduces more branches, which blows up
past 1 million instructions in no-alu32 variant of strobemeta selftests.

Switching len variable from u32 to u64 also fixes the issue and reduces
the number of validated instructions, so use that instead. Fix this
patch and bpf_clamp_umax() removed, both alu32 and no-alu32 selftests
pass.

188bf40391 ath10k: fix invalid dma_addr_t token assignment 
commit 937e79c677 upstream.

Using a kernel pointer in place of a dma_addr_t token can
lead to undefined behavior if that makes it into cache
management functions. The compiler caught one such attempt
in a cast:

drivers/net/wireless/ath/ath10k/mac.c: In function 'ath10k_add_interface':
drivers/net/wireless/ath/ath10k/mac.c:5586:47: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
 5586 |                         arvif->beacon_paddr = (dma_addr_t)arvif->beacon_buf;
      |                                               ^

Looking through how this gets used down the way, I'm fairly
sure that beacon_paddr is never accessed again for ATH10K_DEV_TYPE_HL
devices, and if it was accessed, that would be a bug.

Change the assignment to use a known-invalid address token
instead, which avoids the warning and makes it easier to catch
bugs if it does end up getting used.

d41f4d4dd7 SUNRPC: Partial revert of commit 6f9f17287e 
commit ea7a1019d8 upstream.

The premise of commit 6f9f17287e ("SUNRPC: Mitigate cond_resched() in
xprt_transmit()") was that cond_resched() is expensive and unnecessary
when there has been just a single send.
The point of cond_resched() is to ensure that tasks that should pre-empt
this one get a chance to do so when it is safe to do so. The code prior
to commit 6f9f17287e failed to take into account that it was keeping a
rpc_task pinned for longer than it needed to, and so rather than doing a
full revert, let's just move the cond_resched.

Armada 3700 Functional Specification. According to the specification,
maximal Max Payload Size supported by this device is 512 bytes.

Without this kernel prints suspicious line:

With this change it changes to:

commit c45361abb9 upstream.

When CONFIG_SMP=y, timebase synchronization is required when the second
kernel is started.

arch/powerpc/kernel/smp.c:

  {
  	...
  	if (smp_ops->give_timebase)
  		smp_ops->give_timebase();

  void start_secondary(void *unused)
  {
  	...
  	if (smp_ops->take_timebase)
  		smp_ops->take_timebase();
  	...
  }

When CONFIG_HOTPLUG_CPU=n and CONFIG_KEXEC_CORE=n,
 smp_85xx_ops.give_timebase is NULL,
 smp_85xx_ops.take_timebase is NULL,
As a result, the timebase is not synchronized.

Timebase  synchronization does not depend on CONFIG_HOTPLUG_CPU.

9dcdadd6cc mtd: rawnand: au1550nd: Keep the driver compatible with on-die ECC engines 
commit 7e3cdba176 upstream.

Following the introduction of the generic ECC engine infrastructure, it
was necessary to reorganize the code and move the ECC configuration in
the ->attach_chip() hook. Failing to do that properly lead to a first
series of fixes supposed to stabilize the situation. Unfortunately, this
only fixed the use of software ECC engines, preventing any other kind of
engine to be used, including on-die ones.

It is now time to (finally) fix the situation by ensuring that we still
provide a default (eg. software ECC) but will still support different
ECC engines such as on-die ECC engines if properly described in the
device tree.

There are no changes needed on the core side in order to do this, but we
just need to leverage the logic there which allows:
1- a subsystem default (set to Host engines in the raw NAND world)
2- a driver specific default (here set to software ECC engines)
3- any type of engine requested by the user (ie. described in the DT)

As the raw NAND subsystem has not yet been fully converted to the ECC
engine infrastructure, in order to provide a default ECC engine for this
driver we need to set chip->ecc.engine_type *before* calling
nand_scan(). During the initialization step, the core will consider this
entry as the default engine for this driver. This value may of course
be overloaded by the user if the usual DT properties are provided.
