a13bd9b940 hrtimer: create hrtimer_quiesce_cpu() to isolate CPU from hrtimers
To isolate CPUs (isolate from hrtimers) from sysfs using cpusets, we need some
support from the hrtimer core. i.e. A routine hrtimer_quiesce_cpu() which would
migrate away all the unpinned hrtimers, but shouldn't touch the pinned ones.

This patch creates this routine.

e2e45baa03 hrtimer: update timer->state with 'pinned' information
'Pinned' information would be required in migrate_hrtimers() now, as we can
migrate non-pinned timers away without a hotplug (i.e. with cpuset.quiesce). And
so we may need to identify pinned timers now, as we can't migrate them.

This patch reuses the timer->state variable for setting this flag as there were
enough number of free bits available in this variable. And there is no point
increasing size of this struct by adding another field.

.poll method is declared as returning '__poll_t', a bitwise type.

Fix this by using the proper return type and using the EPOLL
constants instead of the POLL ones, as required for __poll_t.

Rafael J. Wysocki
05ff1ba412 PM: QoS: Invalidate frequency QoS requests after removal
Switching cpufreq drivers (or switching operation modes of the
intel_pstate driver from "active" to "passive" and vice versa)
does not work on some x86 systems with ACPI after commit
3000ce3c52 ("cpufreq: Use per-policy frequency QoS"), because
the ACPI _PPC and thermal code uses the same frequency QoS request
object for a given CPU every time a cpufreq driver is registered
and freq_qos_remove_request() does not invalidate the request after
removing it from its QoS list, so freq_qos_add_request() complains
and fails when that request is passed to it again.

Fix the issue by modifying freq_qos_remove_request() to clear the qos
and type fields of the frequency request pointed to by its argument
after removing it from its QoS list so as to invalidate it.

Commit:

  313ccb9615 ("perf: Allocate context task_ctx_data for child event")

makes the inherit path skip over the current event in case of task_ctx_data
allocation failure. This, however, is inconsistent with allocation failures
in perf_event_alloc(), which would abort the fork.

Correct this by returning an error code on task_ctx_data allocation
failure and failing the fork in that case.

added 'aux_output' bit to the attribute structure, which relies on AUX
events and grouping, neither of which is supported for the kernel events.
This notwithstanding, attempts have been made to use it in the kernel
code, suggesting the necessity of an explicit hard -EINVAL.

While discussing uncore event scheduling, I noticed we do not in fact
seem to dis-allow making uncore-cgroup events. Such events make no
sense what so ever because the cgroup is a CPU local state where
uncore counts across a number of CPUs.

ff51ff84d8 sched/core: Avoid spurious lock dependencies
While seemingly harmless, __sched_fork() does hrtimer_init(), which,
when DEBUG_OBJETS, can end up doing allocations.

This then results in the following lock order:

  rq->lock
    zone->lock.rlock
      batched_entropy_u64.lock

Which in turn causes deadlocks when we do wakeups while holding that
batched_entropy lock -- as the random code does.

Solve this by moving __sched_fork() out from under rq->lock. This is
safe because nothing there relies on rq->lock, as also evident from the
other __sched_fork() callsite.

eb094f0696 Merge branch 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 TSX Async Abort and iTLB Multihit mitigations from Thomas Gleixner:
 "The performance deterioration departement is not proud at all of
  presenting the seventh installment of speculation mitigations and
  hardware misfeature workarounds:

   1) TSX Async Abort (TAA) - 'The Annoying Affair'

      TAA is a hardware vulnerability that allows unprivileged
      speculative access to data which is available in various CPU
      internal buffers by using asynchronous aborts within an Intel TSX
      transactional region.

      The mitigation depends on a microcode update providing a new MSR
      which allows to disable TSX in the CPU. CPUs which have no
      microcode update can be mitigated by disabling TSX in the BIOS if
      the BIOS provides a tunable.

      Newer CPUs will have a bit set which indicates that the CPU is not
      vulnerable, but the MSR to disable TSX will be available
      nevertheless as it is an architected MSR. That means the kernel
      provides the ability to disable TSX on the kernel command line,
      which is useful as TSX is a truly useful mechanism to accelerate
      side channel attacks of all sorts.

   2) iITLB Multihit (NX) - 'No eXcuses'

      iTLB Multihit is an erratum where some Intel processors may incur
      a machine check error, possibly resulting in an unrecoverable CPU
      lockup, when an instruction fetch hits multiple entries in the
      instruction TLB. This can occur when the page size is changed
      along with either the physical address or cache type. A malicious
      guest running on a virtualized system can exploit this erratum to
      perform a denial of service attack.

      The workaround is that KVM marks huge pages in the extended page
      tables as not executable (NX). If the guest attempts to execute in
      such a page, the page is broken down into 4k pages which are
      marked executable. The workaround comes with a mechanism to
      recover these shattered huge pages over time.

  Both issues come with full documentation in the hardware
  vulnerabilities section of the Linux kernel user's and administrator's
  guide.

  Thanks to all patch authors and reviewers who had the extraordinary
  priviledge to be exposed to this nuisance.

  Special thanks to Borislav Petkov for polishing the final TAA patch
  set and to Paolo Bonzini for shepherding the KVM iTLB workarounds and
  providing also the backports to stable kernels for those!"

6e2df0581f sched: Fix pick_next_task() vs 'change' pattern race
Commit 67692435c4 ("sched: Rework pick_next_task() slow-path")
inadvertly introduced a race because it changed a previously
unexplored dependency between dropping the rq->lock and
sched_class::put_prev_task().

The comments about dropping rq->lock, in for example
newidle_balance(), only mentions the task being current and ->on_cpu
being set. But when we look at the 'change' pattern (in for example
sched_setnuma()):

	queued = task_on_rq_queued(p); /* p->on_rq == TASK_ON_RQ_QUEUED */
	running = task_current(rq, p); /* rq->curr == p */

	if (queued)
		dequeue_task(...);
	if (running)
		put_prev_task(...);

	/* change task properties */

	if (queued)
		enqueue_task(...);
	if (running)
		set_next_task(...);

It becomes obvious that if we do this after put_prev_task() has
already been called on @p, things go sideways. This is exactly what
the commit in question allows to happen when it does:

	prev->sched_class->put_prev_task(rq, prev, rf);
	if (!rq->nr_running)
		newidle_balance(rq, rf);

The newidle_balance() call will drop rq->lock after we've called
put_prev_task() and that allows the above 'change' pattern to
interleave and mess up the state.

Furthermore, it turns out we lost the RT-pull when we put the last DL
task.

Fix both problems by extracting the balancing from put_prev_task() and
doing a multi-class balance() pass before put_prev_task().

Pull clone3 stack argument update from Christian Brauner:
 "This changes clone3() to do basic stack validation and to set up the
  stack depending on whether or not it is growing up or down.

  With clone3() the expectation is now very simply that the .stack
  argument points to the lowest address of the stack and that
  .stack_size specifies the initial stack size. This is diferent from
  legacy clone() where the "stack" argument had to point to the lowest
  or highest address of the stack depending on the architecture.

  clone3() was released with 5.3. Currently, it is not documented and
  very unclear to userspace how the stack and stack_size argument have
  to be passed. After talking to glibc folks we concluded that changing
  clone3() to determine stack direction and doing basic validation is
  the right course of action.

  Note, this is a potentially user visible change. In the very unlikely
  case, that it breaks someone's use-case we will revert. (And then e.g.
  place the new behavior under an appropriate flag.)

  Note that passing an empty stack will continue working just as before.
  Breaking someone's use-case is very unlikely. Neither glibc nor musl
  currently expose a wrapper for clone3(). There is currently also no
  real motivation for anyone to use clone3() directly. First, because
  using clone{3}() with stacks requires some assembly (see glibc and
  musl). Second, because it does not provide features that legacy
  clone() doesn't. New features for clone3() will first happen in v5.5
  which is why v5.4 is still a good time to try and make that change now
  and backport it to v5.3.

  I did a codesearch on https://codesearch.debian.net, github, and
  gitlab and could not find any software currently relying directly on
  clone3(). I expect this to change once we land CLONE_CLEAR_SIGHAND
  which was a request coming from glibc at which point they'll likely
  start using it"

clone3: validate stack arguments
Validate the stack arguments and setup the stack depening on whether or not
it is growing down or up.

Legacy clone() required userspace to know in which direction the stack is
growing and pass down the stack pointer appropriately. To make things more
confusing microblaze uses a variant of the clone() syscall selected by
CONFIG_CLONE_BACKWARDS3 that takes an additional stack_size argument.
IA64 has a separate clone2() syscall which also takes an additional
stack_size argument. Finally, parisc has a stack that is growing upwards.
Userspace therefore has a lot nasty code like the following:

 #define __STACK_SIZE (8 * 1024 * 1024)
 pid_t sys_clone(int (*fn)(void *), void *arg, int flags, int *pidfd)
 {
         pid_t ret;
         void *stack;

         stack = malloc(__STACK_SIZE);
         if (!stack)
                 return -ENOMEM;

 #ifdef __ia64__
         ret = __clone2(fn, stack, __STACK_SIZE, flags | SIGCHLD, arg, pidfd);
 #elif defined(__parisc__) /* stack grows up */
         ret = clone(fn, stack, flags | SIGCHLD, arg, pidfd);
 #else
         ret = clone(fn, stack + __STACK_SIZE, flags | SIGCHLD, arg, pidfd);
 #endif
         return ret;
 }

or even crazier variants such as [3].

With clone3() we have the ability to validate the stack. We can check that
when stack_size is passed, the stack pointer is valid and the other way
around. We can also check that the memory area userspace gave us is fine to
use via access_ok(). Furthermore, we probably should not require
userspace to know in which direction the stack is growing. It is easy
for us to do this in the kernel and I couldn't find the original
reasoning behind exposing this detail to userspace.

/* Intentional user visible API change */
clone3() was released with 5.3. Currently, it is not documented and very
unclear to userspace how the stack and stack_size argument have to be
passed. After talking to glibc folks we concluded that trying to change
clone3() to setup the stack instead of requiring userspace to do this is
the right course of action.
Note, that this is an explicit change in user visible behavior we introduce
with this patch. If it breaks someone's use-case we will revert! (And then
e.g. place the new behavior under an appropriate flag.)
Breaking someone's use-case is very unlikely though. First, neither glibc
nor musl currently expose a wrapper for clone3(). Second, there is no real
motivation for anyone to use clone3() directly since it does not provide
features that legacy clone doesn't. New features for clone3() will first
happen in v5.5 which is why v5.4 is still a good time to try and make that
change now and backport it to v5.3. Searches on [4] did not reveal any
packages calling clone3().

52338415cf timekeeping/vsyscall: Update VDSO data unconditionally
The update of the VDSO data is depending on __arch_use_vsyscall() returning
True. This is a leftover from the attempt to map the features of various
architectures 1:1 into generic code.

The usage of __arch_use_vsyscall() in the actual vsyscall implementations
got dropped and replaced by the requirement for the architecture code to
return U64_MAX if the global clocksource is not usable in the VDSO.

But the __arch_use_vsyscall() check in the update code stayed which causes
the VDSO data to be stale or invalid when an architecture actually
implements that function and returns False when the current clocksource is
not usable in the VDSO.

As a consequence the VDSO implementations of clock_getres(), time(),
clock_gettime(CLOCK_.*_COARSE) operate on invalid data and return bogus
information.

Remove the __arch_use_vsyscall() check from the VDSO update function and
update the VDSO data unconditionally.

[ tglx: Massaged changelog and removed the now useless implementations in
  	asm-generic/ARM64/MIPS ]

b0c51f1584 stacktrace: Don't skip first entry on noncurrent tasks
When doing cat /proc/<PID>/stack, the output is missing the first entry.
When the current code walks the stack starting in stack_trace_save_tsk,
it skips all scheduler functions (that's OK) plus one more function. But
this one function should be skipped only for the 'current' task as it is
stack_trace_save_tsk proper.

The original code (before the common infrastructure) skipped one
function only for the 'current' task -- see save_stack_trace_tsk before
3599fe12a1. So do so also in the new infrastructure now.
