Pull irq fix from Thomas Gleixner:
"A last minute fix for a regression introduced in the v6.5 merge
window.
The conversion of the software based interrupt resend mechanism to
hlist missed to add a check whether the descriptor is already enqueued
and dropped the interrupt descriptor lookup for nested interrupts.
The missing check whether the descriptor is already queued causes
hlist corruption and can be observed in the wild. The dropped parent
descriptor lookup has not yet caused problems, but it would result in
stale interrupt line in the worst case.
Add the missing enqueued check and bring the descriptor lookup back to
cure this"

The switch to using hlist for managing software resend of interrupts
broke resend in at least two ways:
First, unconditionally adding interrupt descriptors to the resend list can
corrupt the list when the descriptor in question has already been
added. This causes the resend tasklet to loop indefinitely with interrupts
disabled as was recently reported with the Lenovo ThinkPad X13s after
threaded NAPI was disabled in the ath11k WiFi driver.
This bug is easily fixed by restoring the old semantics of irq_sw_resend()
so that it can be called also for descriptors that have already been marked
for resend.
Second, the offending commit also broke software resend of nested
interrupts by simply discarding the code that made sure that such
interrupts are retriggered using the parent interrupt.
Add back the corresponding code that adds the parent descriptor to the
resend list.

In hw_breakpoint_control(), encode_ctrl_reg() has already encoded the
MWPnCFG3_LoadEn/MWPnCFG3_StoreEn bits in info->ctrl. We don't need to
add (1 << MWPnCFG3_LoadEn | 1 << MWPnCFG3_StoreEn) unconditionally.
Otherwise we can't set read watchpoint and write watchpoint separately.

This is a port of commit 379eb01c21795edb4c ("riscv: Ensure the value
of FP registers in the core dump file is up to date").
The values of FP/SIMD registers in the core dump file come from the
thread.fpu. However, kernel saves the FP/SIMD registers only before
scheduling out the process. If no process switch happens during the
exception handling, kernel will not have a chance to save the latest
values of FP/SIMD registers. So it may cause their values in the core
dump file incorrect. To solve this problem, force fpr_get()/simd_get()
to save the FP/SIMD registers into the thread.fpu if the target task
equals the current task.

The gcc compiler translates on some architectures the 64-bit
__builtin_clzll() function to a call to the libgcc function __clzdi2(),
which should take a 64-bit parameter on 32- and 64-bit platforms.
But in the current kernel code, the built-in __clzdi2() function is
defined to operate (wrongly) on 32-bit parameters if BITS_PER_LONG ==
32, thus the return values on 32-bit kernels are in the range from
[0..31] instead of the expected [0..63] range.
This patch fixes the in-kernel functions __clzdi2() and __ctzdi2() to
take a 64-bit parameter on 32-bit kernels as well, thus it makes the
functions identical for 32- and 64-bit kernels.
This bug went unnoticed since kernel 3.11 for over 10 years, and here
are some possible reasons for that:
a) Some architectures have assembly instructions to count the bits and
which are used instead of calling __clzdi2(), e.g. on x86 the bsr
instruction and on ppc cntlz is used. On such architectures the
wrong __clzdi2() implementation isn't used and as such the bug has
no effect and won't be noticed.
b) Some architectures link to libgcc.a, and the in-kernel weak
functions get replaced by the correct 64-bit variants from libgcc.a.
c) __builtin_clzll() and __clzdi2() doesn't seem to be used in many
places in the kernel, and most likely only in uncritical functions,
e.g. when printing hex values via seq_put_hex_ll(). The wrong return
value will still print the correct number, but just in a wrong
formatting (e.g. with too many leading zeroes).
d) 32-bit kernels aren't used that much any longer, so they are less
tested.
A trivial testcase to verify if the currently running 32-bit kernel is
affected by the bug is to look at the output of /proc/self/maps:
Here the kernel uses a correct implementation of __clzdi2():
root@debian:~# cat /proc/self/maps
00010000-00019000 r-xp 00000000 08:05 787324 /usr/bin/cat

...
and this kernel uses the broken implementation of __clzdi2():
root@debian:~# cat /proc/self/maps
0000000010000-0000000019000 r-xp 00000000 000000008:000000005 787324 /usr/bin/cat

Pull RISC-V fixes from Palmer Dabbelt:
"This is obviously not ideal, particularly for something this late in
the cycle.
Unfortunately we found some uABI issues in the vector support while
reviewing the GDB port, which has triggered a revert -- probably a
good sign we should have reviewed GDB before merging this, I guess I
just dropped the ball because I was so worried about the context
extension and libc suff I forgot. Hence the late revert.
There's some risk here as we're still exposing the vector context for
signal handlers, but changing that would have meant reverting all of
the vector support. The issues we've found so far have been fixed
already and they weren't absolute showstoppers, so we're essentially
just playing it safe by holding ptrace support for another release (or
until we get through a proper userspace code review).
Summary:
- The vector ucontext extension has been extended with vlenb
- The vector registers ELF core dump note type has been changed to
avoid aliasing with the CSR type used in embedded systems
- Support for accessing vector registers via ptrace() has been
reverted
- Another build fix for the ISA spec changes around Zifencei/Zicsr
that manifests on some systems built with binutils-2.37 and
gcc-11.2"

The initial aim is to silence the following objtool warning:
arch/loongarch/kernel/process.o: warning: objtool: arch_cpu_idle_dead() falls through to next function start_thread()
According to tools/objtool/Documentation/objtool.txt, this is because
the last instruction of arch_cpu_idle_dead() is a call to a noreturn
function play_dead(). In order to silence the warning, one simple way
is to add the noreturn function play_dead() to objtool's hard-coded
global_noreturns array, that is to say, just put "NORETURN(play_dead)"
into tools/objtool/noreturns.h, it works well.
But I noticed that play_dead() is only defined once and only called by
arch_cpu_idle_dead(), so put the body of play_dead() into the caller
arch_cpu_idle_dead(), then remove the noreturn function play_dead() is
an alternative way which can reduce the overhead of the function call
at the same time.

If notify_die() returns NOTIFY_STOP, honor the return value from the
handler chain invocation in die() and return without killing the task
as, through a debugger, the fault may have been fixed. It makes sense
even if ignoring the event will make the system unstable: by allowing
access through a debugger it has been compromised already anyway. It
makes our port consistent with x86, arm64, riscv and csky.
Commit 20c0d2d44029 ("[PATCH] i386: pass proper trap numbers to die

As explained by Nick in the original issue: the kernel usually does a
good job of providing library helpers that have similar semantics as
their ordinary userspace libc equivalents, but -ffreestanding disables
such libcall optimization and other related features in the compiler,
which can lead to unexpected things such as CONFIG_FORTIFY_SOURCE not
working (!).
However, due to the desire for better control over unaligned accesses
with respect to CONFIG_ARCH_STRICT_ALIGN, and also for avoiding the
GCC bug https://gcc.gnu.org/PR109465, we do want to still disable
optimizations for the memory libcalls (memcpy, memmove and memset for
now). Use finer-grained -fno-builtin-* toggles to achieve this without
losing source fortification and other libcall optimizations.

Pull tracing fixes from Steven Rostedt:
- Fix ring buffer being permanently disabled due to missed
record_disabled()
Changing the trace cpu mask will disable the ring buffers for the
CPUs no longer in the mask. But it fails to update the snapshot
buffer. If a snapshot takes place, the accounting for the ring buffer
being disabled is corrupted and this can lead to the ring buffer
being permanently disabled.
- Add test case for snapshot and cpu mask working together
- Fix memleak by the function graph tracer not getting closed properly.
The iterator is used to read the ring buffer. When it opens, it calls
the open function of a tracer, and when it is closed, it calls the
close iteration. While a trace is being read, it is still possible to
change the tracer.
If this happens between the function graph tracer and the wakeup
tracer (which uses function graph tracing), the tracers are not
closed properly during when the iterator sees the switch, and the
wakeup function did not initialize its private pointer to NULL, which
is used to know if the function graph tracer was the last tracer. It
could be fooled in thinking it is, but then on exit it does not call
the close function of the function graph tracer to clean up its data.
- Fix synthetic events on big endian machines, by introducing a union
that does the conversions properly.
- Fix synthetic events from printing out the number of elements in the
stacktrace when it shouldn't.
- Fix synthetic events stacktrace to not print a bogus value at the
end.
- Introduce a pipe_cpumask that prevents the trace_pipe files from
being opened by more than one task (file descriptor).
There was a race found where if splice is called, the iter->ent could
become stale and events could be missed. There's no point reading a
producer/consumer file by more than one task as they will corrupt
each other anyway. Add a cpumask that keeps track of the per_cpu
trace_pipe files as well as the global trace_pipe file that prevents
more than one open of a trace_pipe file that represents the same ring
buffer. This prevents the race from happening.
- Fix ftrace samples for arm64 to work with older compilers.

smaps_pte_hole_lookup() is calling shmem_partial_swap_usage() with page
table lock held: but shmem_partial_swap_usage() does cond_resched_rcu() if
need_resched(): "BUG: sleeping function called from invalid context".
Since shmem_partial_swap_usage() is designed to count across a range, but
smaps_pte_hole_lookup() only calls it for a single page slot, just break
out of the loop on the last or only page, before checking need_resched().

The cachestat kselftest runs a test on a normal file, which is created
temporarily in the current directory. Among the tests it runs there is a
call to fsync(), which is expected to clean all dirty pages used by the
file.
However the tmpfs filesystem implements fsync() as noop_fsync(), so the
call will not even attempt to clean anything when this test file happens
to live on a tmpfs instance. This happens in an initramfs, or when the
current directory is in /dev/shm or sometimes /tmp.
To avoid this test failing wrongly, use statfs() to check which filesystem
the test file lives on. If that is "tmpfs", we skip the fsync() test.
Since the fsync test is only one part of the "normal file" test, we now
execute this twice, skipping the fsync part on the first call. This way
only the second test, including the fsync part, would be skipped.

Patch series "selftests: cachestat: fix run on older kernels", v2.
I ran all kernel selftests on some test machine, and stumbled upon
cachestat failing (among others). These patches fix the run on older
kernels and when the current directory is on a tmpfs instance.
This patch (of 2):
As cachestat is a new syscall, it won't be available on older kernels, for
instance those running on a development machine. At the moment the test
reports all tests as "not ok" in this case.
Test for the cachestat syscall availability first, before doing further
tests, and bail out early with a TAP SKIP comment.
This also uses the opportunity to add the proper TAP headers, and add one
check for proper error handling (illegal file descriptor).

The current implementation of append may cause duplicate data and/or
incorrect ranges to be returned to a reader during an update. Although
this has not been reported or seen, disable the append write operation
while the tree is in rcu mode out of an abundance of caution.
During the analysis of the mas_next_slot() the following was
artificially created by separating the writer and reader code:
Writer: reader:
mas_wr_append
set end pivot
updates end metata
Detects write to last slot
last slot write is to start of slot
store current contents in slot
overwrite old end pivot
mas_next_slot():
read end metadata
read old end pivot
return with incorrect range
store new value
Alternatively:
Writer: reader:
mas_wr_append
set end pivot
updates end metata
Detects write to last slot
last lost write to end of slot
store value
mas_next_slot():
read end metadata
read old end pivot
read new end pivot
return with incorrect range
set old end pivot
There may be other accesses that are not safe since we are now updating
both metadata and pointers, so disabling append if there could be rcu
readers is the safest action.

for sharing check
Commit 98b211d6415f ("madvise: convert madvise_free_pte_range() to use a
folio") replaced the page_mapcount() with folio_mapcount() to check
whether the folio is shared by other mapping.
It's not correct for large folios. folio_mapcount() returns the total
mapcount of large folio which is not suitable to detect whether the folio
is shared.
Use folio_estimated_sharers() which returns a estimated number of shares.
That means it's not 100% correct. It should be OK for madvise case here.
User-visible effects is that the THP is skipped when user call madvise.
But the correct behavior is THP should be split and processed then.
NOTE: this change is a temporary fix to reduce the user-visible effects
before the long term fix from David is ready.

large folio for sharing check
Patch series "don't use mapcount() to check large folio sharing", v2.
In madvise_cold_or_pageout_pte_range() and madvise_free_pte_range(),
folio_mapcount() is used to check whether the folio is shared. But it's
not correct as folio_mapcount() returns total mapcount of large folio.
Use folio_estimated_sharers() here as the estimated number is enough.
This patchset will fix the cases:
User space application call madvise() with MADV_FREE, MADV_COLD and
MADV_PAGEOUT for specific address range. There are THP mapped to the
range. Without the patchset, the THP is skipped. With the patch, the
THP will be split and handled accordingly.
David reported the cow self test skip some cases because of MADV_PAGEOUT
skip THP:

0-Day found a 34.6% regression in stress-ng's 'af-alg' test case, and
bisected it to commit b81fac906a8f ("x86/fpu: Move FPU initialization into
arch_cpu_finalize_init()"), which optimizes the FPU init order, and moves
the CR4_OSXSAVE enabling into a later place:
arch_cpu_finalize_init
identify_boot_cpu
identify_cpu
generic_identify
get_cpu_cap --> setup cpu capability
...
fpu__init_cpu
fpu__init_cpu_xstate
cr4_set_bits(X86_CR4_OSXSAVE);
As the FPU is not yet initialized the CPU capability setup fails to set
X86_FEATURE_OSXSAVE. Many security module like 'camellia_aesni_avx_x86_64'
depend on this feature and therefore fail to load, causing the regression.
Cure this by setting X86_FEATURE_OSXSAVE feature right after OSXSAVE
enabling.

The thread flag TIF_NEED_FPU_LOAD indicates that the FPU saved state is
valid and should be reloaded when returning to userspace. However, the
kernel will skip doing this if the FPU registers are already valid as
determined by fpregs_state_valid(). The logic embedded there considers
the state valid if two cases are both true:
1: fpu_fpregs_owner_ctx points to the current tasks FPU state
2: the last CPU the registers were live in was the current CPU.
This is usually correct logic. A CPU’s fpu_fpregs_owner_ctx is set to
the current FPU during the fpregs_restore_userregs() operation, so it
indicates that the registers have been restored on this CPU. But this
alone doesn’t preclude that the task hasn’t been rescheduled to a
different CPU, where the registers were modified, and then back to the
current CPU. To verify that this was not the case the logic relies on the
second condition. So the assumption is that if the registers have been
restored, AND they haven’t had the chance to be modified (by being
loaded on another CPU), then they MUST be valid on the current CPU.
Besides the lazy FPU optimizations, the other cases where the FPU
registers might not be valid are when the kernel modifies the FPU register
state or the FPU saved buffer. In this case the operation modifying the
FPU state needs to let the kernel know the correspondence has been
broken. The comment in “arch/x86/kernel/fpu/context.h” has:
/*
...
* If the FPU register state is valid, the kernel can skip restoring the
* FPU state from memory.
*
* Any code that clobbers the FPU registers or updates the in-memory
* FPU state for a task MUST let the rest of the kernel know that the
* FPU registers are no longer valid for this task.
*
* Either one of these invalidation functions is enough. Invalidate
* a resource you control: CPU if using the CPU for something else
* (with preemption disabled), FPU for the current task, or a task that
* is prevented from running by the current task.
*/
However, this is not completely true. When the kernel modifies the
registers or saved FPU state, it can only rely on
__fpu_invalidate_fpregs_state(), which wipes the FPU’s last_cpu
tracking. The exec path instead relies on fpregs_deactivate(), which sets
the CPU’s FPU context to NULL. This was observed to fail to restore the
reset FPU state to the registers when returning to userspace in the
following scenario:
1. A task is executing in userspace on CPU0
- CPU0’s FPU context points to tasks
- fpu->last_cpu=CPU0
2. The task exec()’s
3. While in the kernel the task is preempted
- CPU0 gets a thread executing in the kernel (such that no other
FPU context is activated)
- Scheduler sets task’s fpu->last_cpu=CPU0 when scheduling out
4. Task is migrated to CPU1
5. Continuing the exec(), the task gets to
fpu_flush_thread()->fpu_reset_fpregs()
- Sets CPU1’s fpu context to NULL
- Copies the init state to the task’s FPU buffer
- Sets TIF_NEED_FPU_LOAD on the task
6. The task reschedules back to CPU0 before completing the exec() and
returning to userspace
- During the reschedule, scheduler finds TIF_NEED_FPU_LOAD is set
- Skips saving the registers and updating task’s fpu→last_cpu,
because TIF_NEED_FPU_LOAD is the canonical source.
7. Now CPU0’s FPU context is still pointing to the task’s, and
fpu->last_cpu is still CPU0. So fpregs_state_valid() returns true even
though the reset FPU state has not been restored.
So the root cause is that exec() is doing the wrong kind of invalidate. It
should reset fpu->last_cpu via __fpu_invalidate_fpregs_state(). Further,
fpu__drop() doesn't really seem appropriate as the task (and FPU) are not
going away, they are just getting reset as part of an exec. So switch to
__fpu_invalidate_fpregs_state().
Also, delete the misleading comment that says that either kind of
invalidate will be enough, because it’s not always the case.

====================
netfilter updates for net
This PR contains nf_tables updates for your *net* tree.
First patch fixes table validation, I broke this in 6.4 when tracking
validation state per table, reported by Pablo, fixup from myself.
Second patch makes sure objects waiting for memory release have been
released, this was broken in 6.1, patch from Pablo Neira Ayuso.
Patch three is a fix-for-fix from previous PR: In case a transaction
gets aborted, gc sequence counter needs to be incremented so pending
gc requests are invalidated, from Pablo.
Same for patch 4: gc list needs to use gc list lock, not destroy lock,
also from Pablo.
Patch 5 fixes a UaF in a set backend, but this should only occur when
failslab is enabled for GFP_KERNEL allocations, broken since feature
was added in 5.6, from myself.
Patch 6 fixes a double-free bug that was also added via previous PR:

====================

Currently, the macvlan over alb bond is broken after commit
14af9963ba1e ("bonding: Support macvlans on top of tlb/rlb mode bonds").
Fix this and add relate tests.
