d1f2d51b71 A pile of Qualcomm clk driver fixes with two main themes: the alpha PLL
driver and shared RCGs, and one fix for the Starfive JH7110 SoC.
 
  - The Alpha PLL clk_ops had multiple problems around setting rates.
    There are a handful of patches here that fix masks and skip enabling
    the clk from set_rate() when the PLL is disabled. The PLLs are
    crucial to operation of the system as almost all frequencies in the
    system are derived from them.
 
  - Parking shared RCGs at a slow always on clk at registration time
    breaks stuff. USB host mode can't handle such a slow frequency and
    the serial console gets all garbled when the UART clk is handed over
    to the kernel. There's a few patches that don't use the shared
    clk_ops for the UART clks and another one to skip parking the USB clk
    at registration time.
 
  - The Starfive PLL driver used for the CPU was busted causing cpufreq
    to fail because the clk didn't change to a safe parent during
    set_rate(). The fix is to register a notifier and switch to a safe
    parent so the PLL can change rate in a glitch free manner.

9d4c304001 KVM: x86: don't fall through case statements without annotations
clang warns on this because it has an unannotated fall-through between
cases:

   arch/x86/kvm/x86.c:4819:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]

and while we could annotate it as a fallthrough, the proper fix is to
just add the break for this case, instead of falling through to the
default case and the break there.

gcc also has that warning, but it looks like gcc only warns for the
cases where they fall through to "real code", rather than to just a
break.  Odd.

890daedec4 RISC-V Fixes for 6.11-rc7
* A revert for the mmap() change that ties the allocation range to the
   hint adress, as what we tried to do ended up regressing on other
   userspace workloads.
 * A fix to avoid a kernel memory leak when emulating misaligned accesses
   from userspace.
 * A Kconfig fix for toolchain vector detection, which now correctly
   detects vector support on toolchains where the V extension depends on
   the M extension.
 * A fix to avoid failing the linear mapping bootmem bounds check on
   NOMMU systems.
 * A fix for early alternatives on relocatable kernels.

 - Grab kvm->srcu when handling KVM_SET_VCPU_EVENTS to guard against accessing

 - Emulate MSR_{FS,GS}_BASE on SVM even though interception is always disabled,

 - Explicitly clear BUS_LOCK_DETECT from KVM's caps on AMD, as KVM doesn't yet

8654fa5ca3 pwm: Fix an off-by-one in the stm32 driver
Hardware engineers tend to start counting at 1 while the software guys
 usually start with 0. This isn't so nice because that results in drivers
 where pwm device #2 needs to use the hardware registers with index 3.
 
 With the commits
 
 	796b942f65 ("mfd: stm32-timers: Add some register definitions with a parameter")
 	7cea05ae1d ("pwm-stm32: Make use of parametrised register definitions")
 
 (merged for v6.11-rc1) I tried to improve the situation and make this
 counting mismatch more explicit and transparent. However in one instance
 I failed to add the needed +1.
 
 This was noticed by Fabrice Gasnier (however in a way that made me
 hesitate to add a "Reported-by:" tag, see
 https://lore.kernel.org/linux-pwm/3515a8f3-436e-4d14-9bac-dfe6aa869819@foss.st.com),
 thanks to him for catching the issue.
 
 A small patch fixing that mismatch is the only change included here.

4e32c25b58 libfs: fix get_stashed_dentry()
get_stashed_dentry() tries to optimistically retrieve a stashed dentry
from a provided location.  It needs to ensure to hold rcu lock before it
dereference the stashed location to prevent UAF issues.  Use
rcu_dereference() instead of READ_ONCE() it's effectively equivalent
with some lockdep bells and whistles and it communicates clearly that
this expects rcu protection.

f8e1ca92e3 dm-integrity: fix a race condition when accessing recalc_sector
There's a race condition when accessing the variable
ic->sb->recalc_sector. The function integrity_recalc writes to this
variable when it makes some progress and the function
dm_integrity_map_continue may read this variable concurrently.

One problem is that on 32-bit architectures the 64-bit variable is not
read and written atomically - it may be possible to read garbage if read
races with write.

Another problem is that memory accesses to this variable are not guarded
with memory barriers.

This commit fixes the race - it moves reading ic->sb->recalc_sector to an
earlier place where we hold &ic->endio_wait.lock.

e4b42053b7 Tracing fixes for 6.11:
- Fix adding a new fgraph callback after function graph tracing has
   already started.
 
   If the new caller does not initialize its hash before registering the
   fgraph_ops, it can cause a NULL pointer dereference. Fix this by adding
   a new parameter to ftrace_graph_enable_direct() passing in the newly
   added gops directly and not rely on using the fgraph_array[], as entries
   in the fgraph_array[] must be initialized. Assign the new gops to the
   fgraph_array[] after it goes through ftrace_startup_subops() as that
   will properly initialize the gops->ops and initialize its hashes.
 
 - Fix a memory leak in fgraph storage memory test.
 
   If the "multiple fgraph storage on a function" boot up selftest
   fails in the registering of the function graph tracer, it will
   not free the memory it allocated for the filter. Break the loop
   up into two where it allocates the filters first and then registers
   the functions where any errors will do the appropriate clean ups.
 
 - Only clear the timerlat timers if it has an associated kthread.
 
   In the rtla tool that uses timerlat, if it was killed just as it
   was shutting down, the signals can free the kthread and the timer.
   But the closing of the timerlat files could cause the hrtimer_cancel()
   to be called on the already freed timer. As the kthread variable is
   is set to NULL when the kthreads are stopped and the timers are freed
   it can be used to know not to call hrtimer_cancel() on the timer if
   the kthread variable is NULL.
 
 - Use a cpumask to keep track of osnoise/timerlat kthreads
 
   The timerlat tracer can use user space threads for its analysis.
   With the killing of the rtla tool, the kernel can get confused
   between if it is using a user space thread to analyze or one of its
   own kernel threads. When this confusion happens, kthread_stop()
   can be called on a user space thread and bad things happen.
   As the kernel threads are per-cpu, a bitmask can be used to know
   when a kernel thread is used or when a user space thread is used.
 
 - Add missing interface_lock to osnoise/timerlat stop_kthread()
 
   The stop_kthread() function in osnoise/timerlat clears the
   osnoise kthread variable, and if it was a user space thread does
   a put_task on it. But this can race with the closing of the timerlat
   files that also does a put_task on the kthread, and if the race happens
   the task will have put_task called on it twice and oops.
 
 - Add cond_resched() to the tracing_iter_reset() loop.
 
   The latency tracers keep writing to the ring buffer without resetting
   when it issues a new "start" event (like interrupts being disabled).
   When reading the buffer with an iterator, the tracing_iter_reset()
   sets its pointer to that start event by walking through all the events
   in the buffer until it gets to the time stamp of the start event.
   In the case of a very large buffer, the loop that looks for the start
   event has been reported taking a very long time with a non preempt kernel
   that it can trigger a soft lock up warning. Add a cond_resched() into
   that loop to make sure that doesn't happen.
 
 - Use list_del_rcu() for eventfs ei->list variable
 
   It was reported that running loops of creating and deleting  kprobe events
   could cause a crash due to the eventfs list iteration hitting a LIST_POISON
   variable. This is because the list is protected by SRCU but when an item is
   deleted from the list, it was using list_del() which poisons the "next"
   pointer. This is what list_del_rcu() was to prevent.

031ae72825 ila: call nf_unregister_net_hooks() sooner
syzbot found an use-after-free Read in ila_nf_input [1]

Issue here is that ila_xlat_exit_net() frees the rhashtable,
then call nf_unregister_net_hooks().

It should be done in the reverse way, with a synchronize_rcu().

This is a good match for a pre_exit() method.

Parsing Generic Netlink notification messages performs lookup for op in

GenlMsg, thus msg.cmd() returns Generic Netlink family id (19) instead of
proper notification command id (i.e.: DPLL_CMD_PIN_CHANGE_NTF=13).

Allow the op to be obtained within NetlinkProtocol.decode(..) itself if the
op was not passed to the decode function, thus allow parsing of Generic
Netlink notifications without causing the failure.

59cbd4eea4 KVM: Remove HIGH_RES_TIMERS dependency
Commit 92b5265d38 ("KVM: Depend on HIGH_RES_TIMERS") added a dependency
to high resolution timers with the comment:

    KVM lapic timer and tsc deadline timer based on hrtimer,
    setting a leftmost node to rb tree and then do hrtimer reprogram.
    If hrtimer not configured as high resolution, hrtimer_enqueue_reprogram
    do nothing and then make kvm lapic timer and tsc deadline timer fail.

That was back in 2012, where hrtimer_start_range_ns() would do the
reprogramming with hrtimer_enqueue_reprogram(). But as that was a nop with
high resolution timers disabled, this did not work. But a lot has changed
in the last 12 years.

For example, commit 49a2a07514 ("hrtimer: Kick lowres dynticks targets on
timer enqueue") modifies __hrtimer_start_range_ns() to work with low res
timers. There's been lots of other changes that make low res work.

ChromeOS has tested this before as well, and it hasn't seen any issues
with running KVM with high res timers disabled.  There could be problems,
especially at low HZ, for guests that do not support kvmclock and rely
on precise delivery of periodic timers to keep their clock running.
This can be the APIC timer (provided by the kernel), the RTC (provided
by userspace), or the i8254 (choice of kernel/userspace).  These guests
are few and far between these days, and in the case of the APIC timer +
Intel hosts we can use the preemption timer (which is TSC-based and has
better latency _and_ accuracy).

In KVM, only x86 is requiring CONFIG_HIGH_RES_TIMERS; perhaps a "depends
on HIGH_RES_TIMERS || EXPERT" could be added to virt/kvm, or a pr_warn
could be added to kvm_init if HIGH_RES_TIMERS are not enabled.  But in
general, it seems that there must be other code in the kernel (maybe
sound/?) that is relying on having high-enough HZ or hrtimers but that's
not documented anywhere.  Whenever you disable it you probably need to
know what you're doing and what your workload is; so the dependency is
not particularly interesting, and we can just remove it.

5bfbcd1ee5 tracing/timerlat: Add interface_lock around clearing of kthread in stop_kthread()
The timerlat interface will get and put the task that is part of the
"kthread" field of the osn_var to keep it around until all references are
released. But here's a race in the "stop_kthread()" code that will call
put_task_struct() on the kthread if it is not a kernel thread. This can
race with the releasing of the references to that task struct and the
put_task_struct() can be called twice when it should have been called just
once.

Take the interface_lock() in stop_kthread() to synchronize this change.
But to do so, the function stop_per_cpu_kthreads() needs to change the
loop from for_each_online_cpu() to for_each_possible_cpu() and remove the
cpu_read_lock(), as the interface_lock can not be taken while the cpu
locks are held. The only side effect of this change is that it may do some
extra work, as the per_cpu variables of the offline CPUs would not be set
anyway, and would simply be skipped in the loop.

Remove unneeded "return;" in stop_kthread().

e6a53481da tracing/timerlat: Only clear timer if a kthread exists
The timerlat tracer can use user space threads to check for osnoise and
timer latency. If the program using this is killed via a SIGTERM, the
threads are shutdown one at a time and another tracing instance can start
up resetting the threads before they are fully closed. That causes the
hrtimer assigned to the kthread to be shutdown and freed twice when the
dying thread finally closes the file descriptors, causing a use-after-free
bug.

Only cancel the hrtimer if the associated thread is still around. Also add
the interface_lock around the resetting of the tlat_var->kthread.

Note, this is just a quick fix that can be backported to stable. A real
fix is to have a better synchronization between the shutdown of old
threads and the starting of new ones.
