      s390/vx: add vx-insn.h wrapper include file · 706f2ada
      Heiko Carstens authored 
      
The vector instruction macros can also be used in inline assemblies. For
this the magic

asm(".include \"asm/vx-insn.h\"\n");

must be added to C files in order to avoid that the pre-processor
eliminates the __ASSEMBLY__ guarded macros. This however comes with the
problem that changes to asm/vx-insn.h do not cause a recompile of C files
which have only this magic statement instead of a proper include statement.
This can be observed with the arch/s390/kernel/fpu.c file.

In order to fix this problem and also to avoid that the include must
be specified twice, add a wrapper include header file which will do
all necessary steps.

This way only the vx-insn.h header file needs to be included and changes to
the new vx-insn-asm.h header file cause a recompile of all dependent files
like it should.

      rust: add `build_error` crate · ecaa6ddf
      Gary Guo authored 
      
The `build_error` crate provides a function `build_error` which
will panic at compile-time if executed in const context and,
by default, will cause a build error if not executed at compile
time and the optimizer does not optimise away the call.

The `CONFIG_RUST_BUILD_ASSERT_ALLOW` kernel option allows to
relax the default build failure and convert it to a runtime
check. If the runtime check fails, `panic!` will be called.

Its functionality will be exposed to users as a couple macros in
the `kernel` crate in the following patch, thus some documentation
here refers to them for simplicity.

      debugobjects: Print object pointer in debug_print_object() · c4db2d3b
      Stephen Boyd authored 
      
Delayed kobject debugging (CONFIG_DEBUG_KOBJECT_RELEASE) prints the kobject
pointer that's being released in kobject_release() before scheduling a
randomly delayed work to do the actual release work.

If the caller of kobject_put() frees the kobject upon return then this will
typically emit a debugobject warning about freeing an active timer.

Usually the release function is the function that does the kfree() of the
struct containing the kobject.

For example the following print is seen

 kobject: 'queue' (ffff888114236190): kobject_release, parent 0000000000000000 (delayed 1000)
 ------------[ cut here ]------------
 ODEBUG: free active (active state 0) object type: timer_list hint: kobject_delayed_cleanup+0x0/0x390

but the kobject printk cannot be matched with the debug object printk
because it could be any number of kobjects that was released around that
time. The random delay for the work doesn't help either.

Print the address of the object being tracked to help to figure out which
kobject is the problem here. Note that this does not use %px here to match
the other %p usage in debugobject debugging. Due to %p usage it is required
to disable pointer hashing to correlate the two pointer printks.

      percpu_counter: add percpu_counter_sum_all interface · f689054a
      Shakeel Butt authored 
      The percpu_counter is used for scenarios where performance is more
important than the accuracy.  For percpu_counter users, who want more
accurate information in their slowpath, percpu_counter_sum is provided
which traverses all the online CPUs to accumulate the data.  The reason it
only needs to traverse online CPUs is because percpu_counter does
implement CPU offline callback which syncs the local data of the offlined
CPU.

However there is a small race window between the online CPUs traversal of
percpu_counter_sum and the CPU offline callback.  The offline callback has
to traverse all the percpu_counters on the system to flush the CPU local
data which can be a lot.  During that time, the CPU which is going offline
has already been published as offline to all the readers.  So, as the
offline callback is running, percpu_counter_sum can be called for one
counter which has some state on the CPU going offline.  Since
percpu_counter_sum only traverses online CPUs, it will skip that specific
CPU and the offline callback might not have flushed the state for that
specific percpu_counter on that offlined CPU.

Normally this is not an issue because percpu_counter users can deal with
some inaccuracy for small time window.  However a new user i.e.  mm_struct
on the cleanup path wants to check the exact state of the percpu_counter
through check_mm().  For such users, this patch introduces
percpu_counter_sum_all() which traverses all possible CPUs and it is used
in fork.c:check_mm() to avoid the potential race.

This issue is exposed by the later patch "mm: convert mm's rss stats into
percpu_counter".

      mm/slub, kunit: Add a test case for kmalloc redzone check · 6cd6d33c
      Feng Tang authored and Vlastimil Babka's avatar Vlastimil Babka committed 
      
kmalloc redzone check for slub has been merged, and it's better to add
a kunit case for it, which is inspired by a real-world case as described
in commit 120ee599 ("staging: octeon-usb: prevent memory corruption"):

"
  octeon-hcd will crash the kernel when SLOB is used. This usually happens
  after the 18-byte control transfer when a device descriptor is read.
  The DMA engine is always transferring full 32-bit words and if the
  transfer is shorter, some random garbage appears after the buffer.
  The problem is not visible with SLUB since it rounds up the allocations
  to word boundary, and the extra bytes will go undetected.
"

To avoid interrupting the normal functioning of kmalloc caches, a
kmem_cache mimicing kmalloc cache is created with similar flags, and
kmalloc_trace() is used to really test the orig_size and redzone setup.

      mm/slub, kunit: add SLAB_SKIP_KFENCE flag for cache creation · 4d9dd4b0
      Feng Tang authored and Vlastimil Babka's avatar Vlastimil Babka committed 
      
When kfence is enabled, the buffer allocated from the test case
could be from a kfence pool, and the operation could be also
caught and reported by kfence first, causing the case to fail.

With default kfence setting, this is very difficult to be triggered.
By changing CONFIG_KFENCE_NUM_OBJECTS from 255 to 16383, and
CONFIG_KFENCE_SAMPLE_INTERVAL from 100 to 5, the allocation from
kfence did hit 7 times in different slub_kunit cases out of 900
times of boot test.

To avoid this, initially we tried is_kfence_address() to check this
and repeated allocation till finding a non-kfence address. Vlastimil
Babka suggested SLAB_SKIP_KFENCE flag could be used to achieve this,
and better add a wrapper function for simplifying cache creation.

      percpu-refcount: Use call_rcu_hurry() for atomic switch · 343a72e5
      Joel Fernandes (Google) authored 
      
Earlier commits in this series allow battery-powered systems to build
their kernels with the default-disabled CONFIG_RCU_LAZY=y Kconfig option.
This Kconfig option causes call_rcu() to delay its callbacks in order to
batch callbacks.  This means that a given RCU grace period covers more
callbacks, thus reducing the number of grace periods, in turn reducing
the amount of energy consumed, which increases battery lifetime which
can be a very good thing.  This is not a subtle effect: In some important
use cases, the battery lifetime is increased by more than 10%.

This CONFIG_RCU_LAZY=y option is available only for CPUs that offload
callbacks, for example, CPUs mentioned in the rcu_nocbs kernel boot
parameter passed to kernels built with CONFIG_RCU_NOCB_CPU=y.

Delaying callbacks is normally not a problem because most callbacks do
nothing but free memory.  If the system is short on memory, a shrinker
will kick all currently queued lazy callbacks out of their laziness,
thus freeing their memory in short order.  Similarly, the rcu_barrier()
function, which blocks until all currently queued callbacks are invoked,
will also kick lazy callbacks, thus enabling rcu_barrier() to complete
in a timely manner.

However, there are some cases where laziness is not a good option.
For example, synchronize_rcu() invokes call_rcu(), and blocks until
the newly queued callback is invoked.  It would not be a good for
synchronize_rcu() to block for ten seconds, even on an idle system.
Therefore, synchronize_rcu() invokes call_rcu_hurry() instead of
call_rcu().  The arrival of a non-lazy call_rcu_hurry() callback on a
given CPU kicks any lazy callbacks that might be already queued on that
CPU.  After all, if there is going to be a grace period, all callbacks
might as well get full benefit from it.

Yes, this could be done the other way around by creating a
call_rcu_lazy(), but earlier experience with this approach and
feedback at the 2022 Linux Plumbers Conference shifted the approach
to call_rcu() being lazy with call_rcu_hurry() for the few places
where laziness is inappropriate.

And another call_rcu() instance that cannot be lazy is the one on the
percpu refcounter's "per-CPU to atomic switch" code path, which
uses RCU when switching to atomic mode.  The enqueued callback
wakes up waiters waiting in the percpu_ref_switch_waitq.  Allowing
this callback to be lazy would result in unacceptable slowdowns for
users of per-CPU refcounts, such as blk_pre_runtime_suspend().

Therefore, make __percpu_ref_switch_to_atomic() use call_rcu_hurry()
in order to revert to the old behavior.
