There is currently nothing preventing tasks from changing their per-task
clamp values in anyway that they like. The rationale is probably that
system administrators are still able to limit those clamps thanks to the
cgroup interface. However, this causes pain in a system where both
per-task and per-cgroup clamp values are expected to be under the
control of core system components (as is the case for Android).
To fix this, let's require CAP_SYS_NICE to change per-task clamp values.
There are ongoing discussions upstream about more flexible approaches
than this using the RLIMIT API -- see [1]. But the upstream discussion
has not converged yet, and this is way too late for UAPI changes in
android12-5.10 anyway, so let's apply this change which provides the
behaviour we want without actually impacting UAPIs.

Double enqueues in rt runqueues (list) have been reported while running
a simple test that spawns a number of threads doing a short sleep/run
pattern while being concurrently setscheduled between rt and fair class.

__sched_setscheduler() uses rt_effective_prio() to handle proper queuing
of priority boosted tasks that are setscheduled while being boosted.
rt_effective_prio() is however called twice per each
__sched_setscheduler() call: first directly by __sched_setscheduler()
before dequeuing the task and then by __setscheduler() to actually do
the priority change. If the priority of the pi_top_task is concurrently
being changed however, it might happen that the two calls return
different results. If, for example, the first call returned the same rt
priority the task was running at and the second one a fair priority, the
task won't be removed by the rt list (on_list still set) and then
enqueued in the fair runqueue. When eventually setscheduled back to rt
it will be seen as enqueued already and the WARNING/BUG be issued.
Fix this by calling rt_effective_prio() only once and then reusing the
return value. While at it refactor code as well for clarity. Concurrent
priority inheritance handling is still safe and will eventually converge
to a new state by following the inheritance chain(s).

SCHED_FLAG_KEEP_PARAMS can be passed to sched_setattr to specify that
the call must not touch scheduling parameters (nice or priority). This
is particularly handy for uclamp when used in conjunction with
SCHED_FLAG_KEEP_POLICY as that allows to issue a syscall that only
impacts uclamp values.
However, sched_setattr always checks whether the priorities and nice
values passed in sched_attr are valid first, even if those never get
used down the line. This is useless at best since userspace can
trivially bypass this check to set the uclamp values by specifying low
priorities. However, it is cumbersome to do so as there is no single
expression of this that skips both RT and CFS checks at once. As such,
userspace needs to query the task policy first with e.g. sched_getattr
and then set sched_attr.sched_priority accordingly. This is racy and
slower than a single call.
As the priority and nice checks are useless when SCHED_FLAG_KEEP_PARAMS
is specified, simply inherit them in this case to match the policy
inheritance of SCHED_FLAG_KEEP_POLICY.

SCHED_FLAG_SUGOV is supposed to be a kernel-only flag that userspace
cannot interact with. However, sched_getattr() currently reports it
in sched_flags if called on a sugov worker even though it is not
actually defined in a UAPI header. To avoid this, make sure to
clean-up the sched_flags field in sched_getattr() before returning to
userspace.

The UCLAMP_FLAG_IDLE flag is set on a runqueue when dequeueing the last
uclamp active task (that is, when buckets.tasks reaches 0 for all
buckets) to maintain the last uclamp.max and prevent blocked util from
suddenly becoming visible.
However, there is an asymmetry in how the flag is set and cleared which
can lead to having the flag set whilst there are active tasks on the rq.
Specifically, the flag is cleared in the uclamp_rq_inc() path, which is
called at enqueue time, but set in uclamp_rq_dec_id() which is called
both when dequeueing a task _and_ in the update_uclamp_active() path. As
a result, when both uclamp_rq_{dec,ind}_id() are called from
update_uclamp_active(), the flag ends up being set but not cleared,
hence leaving the runqueue in a broken state.
Fix this by clearing the flag in update_uclamp_active() as well.

[ Upstream commit 0213b7083e81f4acd69db32cb72eb4e5f220329a ]
Now cpu.uclamp.min acts as a protection, we need to make sure that the
uclamp request of the task is within the allowed range of the cgroup,
that is it is clamp()'ed correctly by tg->uclamp[UCLAMP_MIN] and
tg->uclamp[UCLAMP_MAX].
As reported by Xuewen [1] we can have some corner cases where there's
inversion between uclamp requested by task (p) and the uclamp values of
the taskgroup it's attached to (tg). Following table demonstrates
2 corner cases:
| p | tg | effective
-----------+-----+------+-----------
CASE 1
-----------+-----+------+-----------
uclamp_min | 60% | 0% | 60%
-----------+-----+------+-----------
uclamp_max | 80% | 50% | 50%
-----------+-----+------+-----------
CASE 2
-----------+-----+------+-----------
uclamp_min | 0% | 30% | 30%
-----------+-----+------+-----------
uclamp_max | 20% | 50% | 20%
-----------+-----+------+-----------
With this fix we get:
| p | tg | effective
-----------+-----+------+-----------
CASE 1
-----------+-----+------+-----------
uclamp_min | 60% | 0% | 50%
-----------+-----+------+-----------
uclamp_max | 80% | 50% | 50%
-----------+-----+------+-----------
CASE 2
-----------+-----+------+-----------
uclamp_min | 0% | 30% | 30%
-----------+-----+------+-----------
uclamp_max | 20% | 50% | 30%
-----------+-----+------+-----------
Additionally uclamp_update_active_tasks() must now unconditionally
update both UCLAMP_MIN/MAX because changing the tg's UCLAMP_MAX for
instance could have an impact on the effective UCLAMP_MIN of the tasks.
| p | tg | effective

cpu_cgroup_css_online() calls cpu_util_update_eff() without holding the
uclamp_mutex or rcu_read_lock() like other call sites, which is
a mistake.
The uclamp_mutex is required to protect against concurrent reads and
writes that could update the cgroup hierarchy.
The rcu_read_lock() is required to traverse the cgroup data structures
in cpu_util_update_eff().
Surround the caller with the required locks and add some asserts to
better document the dependency in cpu_util_update_eff().

cpu.uclamp.min is a protection as described in cgroup-v2 Resource
Distribution Model
Documentation/admin-guide/cgroup-v2.rst
which means we try our best to preserve the minimum performance point of
tasks in this group. See full description of cpu.uclamp.min in the
cgroup-v2.rst.
But the current implementation makes it a limit, which is not what was
intended.
For example:
tg->cpu.uclamp.min = 20%
p0->uclamp[UCLAMP_MIN] = 0
p1->uclamp[UCLAMP_MIN] = 50%
Previous Behavior (limit):
p0->effective_uclamp = 0
p1->effective_uclamp = 20%
New Behavior (Protection):
p0->effective_uclamp = 20%
p1->effective_uclamp = 50%
Which is inline with how protections should work.
With this change the cgroup and per-task behaviors are the same, as
expected.
Additionally, we remove the confusing relationship between cgroup and
!user_defined flag.
We don't want for example RT tasks that are boosted by default to max to
change their boost value when they attach to a cgroup. If a cgroup wants
to limit the max performance point of tasks attached to it, then
cpu.uclamp.max must be set accordingly.
Or if they want to set different boost value based on cgroup, then
sysctl_sched_util_clamp_min_rt_default must be used to NOT boost to max
and set the right cpu.uclamp.min for each group to let the RT tasks
obtain the desired boost value when attached to that group.
As it stands the dependency on !user_defined flag adds an extra layer of
complexity that is not required now cpu.uclamp.min behaves properly as
a protection.
The propagation model of effective cpu.uclamp.min in child cgroups as
implemented by cpu_util_update_eff() is still correct. The parent
protection sets an upper limit of what the child cgroups will
effectively get.

[ Upstream commit f1a0a376ca0c4ef1fc3d24e3e502acbb5b795674 ]
As pointed out by commit
de9b8f5dcb ("sched: Fix crash trying to dequeue/enqueue the idle thread")
init_idle() can and will be invoked more than once on the same idle
task. At boot time, it is invoked for the boot CPU thread by
sched_init(). Then smp_init() creates the threads for all the secondary
CPUs and invokes init_idle() on them.
As the hotplug machinery brings the secondaries to life, it will issue
calls to idle_thread_get(), which itself invokes init_idle() yet again.
In this case it's invoked twice more per secondary: at _cpu_up(), and at
bringup_cpu().
Given smp_init() already initializes the idle tasks for all *possible*
CPUs, no further initialization should be required. Now, removing
init_idle() from idle_thread_get() exposes some interesting expectations
with regards to the idle task's preempt_count: the secondary startup always
issues a preempt_disable(), requiring some reset of the preempt count to 0
between hot-unplug and hotplug, which is currently served by
idle_thread_get() -> idle_init().
Given the idle task is supposed to have preemption disabled once and never
see it re-enabled, it seems that what we actually want is to initialize its
preempt_count to PREEMPT_DISABLED and leave it there. Do that, and remove
init_idle() from idle_thread_get().
Secondary startups were patched via coccinelle:

select_fallback_rq() must return a cpu that is valid for the task.
However, when nid is not -1, it skips checking for
task_cpu_possible_mask().
This causes a problem when execve-ing 32 bit apps on an asymmetric
system where not all cpus are 32 bit capable. During execve-ing
the task is marked as 32 bit long before its affinity mask is
restricted.
If the cpu goes offline during this time, select_fallback_rq()
could return a 64 bit only cpu, which __migrate_tasks()/
is_cpu_allowed() rejects.
migrate_tasks() will therefore continue to pick the same task
repeatedly, where __migrate_tasks() rejects the cpu chosen
by select_fallback_rq() every time, leading to an infinite loop.
Correct the issue by updating select_fallback_rq() for the case
where nid is not -1, ensuring that the returned cpu is always
valid for this task.

Asymmetric systems may not offer the same level of userspace ISA support
across all CPUs, meaning that some applications cannot be executed by
some CPUs. As a concrete example, upcoming arm64 big.LITTLE designs do
not feature support for 32-bit applications on both clusters.
Although we take care to prevent explicit hot-unplug of all 32-bit
capable CPUs on such a system, this is required when suspending on some
SoCs where the firmware mandates that the suspend/resume operation is
handled by CPU 0, which may not be capable of running 32-bit tasks.
Consequently, there is a window on the resume path where no 32-bit
capable CPUs are available for scheduling and waking up a 32-bit task
will result in a scheduler BUG() due to failure of select_fallback_rq():

Migrating a task to a CPU which is concurrently being taken offline can
cause the migration to fail silently, with the task left running on the
old CPU. This is usually not the end of the world, but when forcefully
migrating a 32-bit task during execve() from a 64-bit task, it is
imperative that we do not attempt to return to userspace on a
64-bit-only CPU.
Take the CPU hotplug lock for read while forcefully migrating a 32-bit

task with a clamp of 1024 will be mapped to bucket id 1024/51=20. Sadly,
correct indexes are in range [0,19], hence leading to an out of bound
memory access.
Clamp the bucket id to fix the issue.

In case the user wants to stop controlling a uclamp constraint value
for a task, use the magic value -1 in sched_util_{min,max} with the
appropriate sched_flags (SCHED_FLAG_UTIL_CLAMP_{MIN,MAX}) to indicate
the reset.
The advantage over the 'additional flag' approach (i.e. introducing
SCHED_FLAG_UTIL_CLAMP_RESET) is that no additional flag has to be
exported via uapi. This avoids the need to document how this new flag
has be used in conjunction with the existing uclamp related flags.
The following subtle issue is fixed as well. When a uclamp constraint
value is set on a !user_defined uclamp_se it is currently first reset
and then set.
Fix this by AND'ing !user_defined with !SCHED_FLAG_UTIL_CLAMP which
stands for the 'sched class change' case.
The related condition 'if (uc_se->user_defined)' moved from
__setscheduler_uclamp() into uclamp_reset().

commit 1139aeb1c521eb4a050920ce6c64c36c4f2a3ab7 upstream.
As of commit 966a967116 ("smp: Avoid using two cache lines for struct
call_single_data"), the smp code prefers 32-byte aligned call_single_data
objects for performance reasons, but the block layer includes an instance
of this structure in the main 'struct request' that is more senstive
to size than to performance here, see 4ccafe0320 ("block: unalign
call_single_data in struct request").
The result is a violation of the calling conventions that clang correctly
points out:
block/blk-mq.c:630:39: warning: passing 8-byte aligned argument to 32-byte aligned parameter 2 of 'smp_call_function_single_async' may result in an unaligned pointer access [-Walign-mismatch]
smp_call_function_single_async(cpu, &rq->csd);
It does seem that the usage of the call_single_data without cache line
alignment should still be allowed by the smp code, so just change the
function prototype so it accepts both, but leave the default alignment
unchanged for the other users. This seems better to me than adding
a local hack to shut up an otherwise correct warning in the caller.

Util-clamp places tasks in different buckets based on their clamp values
for performance reasons. However, the size of buckets is currently
computed using a rounding division, which can lead to an off-by-one
error in some configurations.
For instance, with 20 buckets, the bucket size will be 1024/20=51. A
task with a clamp of 1024 will be mapped to bucket id 1024/51=20. Sadly,
correct indexes are in range [0,19], hence leading to an out of bound
memory access.
Clamp the bucket id to fix the issue.

Currently, the sched code checks if the rq clock has been
updated after its lock has been held when CONFIG_SCHED_DEBUG
is enabled. It tracks this by clearing the RQCF_UPDATED bit
when a lock is acquired and setting it upon a subsequent
update_rq_clock() call. It warns if rq clock is read without
RQCF_UPDATED flag indicating the code path missed updating
the clock.
When migrate_tasks() is called during a pause_cpus() event,
the local variable orf is updated with the contents of *rf,
prior to the call to update_rq_clock(). As a result, when
migrate_tasks() restores *rf from the local variable the
RQCF_UPDATED flag is lost. This clearing out of the
RQCF_UPDATED flag leads to a warning when the next task
is being pushed out.
For example in migrate_tasks()
orf = rf; // save flags, RQCF_UPDATE cleared
update_rq_clock() // set RQCF_UPDATE
for()
...
__migrate_task(dead_rq, new_cpu)
...
--> if migration, restore dead_rq's flags with orf.
--> We loose RQCF_UPDATE
rq_relock(dead_rq, orf)
This leaves the current cpu's rq clock_update_flags with the
RQCF_UPDATED flag cleared, an error condition with
CONFIG_SCHED_DEBUG enabled.
Fix the issue for by ensuring that the local variable orf
has the RQCF_UPDATED flag set, allowing the current
CPU's rq to have the flag set and leaving it in a good state
for future usage.
pause_cpus() is currently Android specific. As cpu_pause does
not rely on stop_machine_cpuslocked() like the regular
hotunplug path does, there's a risk for another CPU to
read the rq_clock, after we cleared RQCF_UPDATE, when using
pause_cpus(). This change will have little or no impact outside
of Android currently. If pause_cpus() or drain_rq_cpu_stop()
are merged upstream this change should be merged as well.

Vendors want to get en/dequeueing information and update
some vendor-managed data to modifiy DVFS or scheduling behavior.
But in the current hooking positions, vendors get the information
after all behaviors they want to modify are done.
So need to move the hooks before en/dequeue callbacks
to achieve the "true" goals.

Vendor may have their own behavior for determing uclamp value. Also
uclamp_eff_get() is used in uclamp_rq_inc_id() when task is enqueued,
and it is contained in uclamp_eff_value(), there is no much benefit to
hook uclamp_eff_value(), so remove the hook in uclamp_eff_value().

[ Upstream commit 156ec6f42b8d300dbbf382738ff35c8bad8f4c3a ]
Hung tasks and RCU stall cases were reported on systems which were not
100% busy. Investigation of such unexpected cases (no sign of potential
starvation caused by tasks hogging the system) pointed out that the
periodic sched tick timer wasn't serviced anymore after a certain point
and that caused all machinery that depends on it (timers, RCU, etc.) to
stop working as well. This issues was however only reproducible if
HRTICK was enabled.
Looking at core dumps it was found that the rbtree of the hrtimer base
used also for the hrtick was corrupted (i.e. next as seen from the base
root and actual leftmost obtained by traversing the tree are different).
Same base is also used for periodic tick hrtimer, which might get "lost"
if the rbtree gets corrupted.
Much alike what described in commit 1f71addd34 ("tick/sched: Do not
mess with an enqueued hrtimer") there is a race window between
hrtimer_set_expires() in hrtick_start and hrtimer_start_expires() in
__hrtick_restart() in which the former might be operating on an already
queued hrtick hrtimer, which might lead to corruption of the base.
Use hrtick_start() (which removes the timer before enqueuing it back) to
ensure hrtick hrtimer reprogramming is entirely guarded by the base
lock, so that no race conditions can occur.

commit 1b7af295541d75535374325fd617944534853919 upstream.
The try_invoke_on_locked_down_task() function currently requires
that interrupts be enabled, but it is called with interrupts
disabled from rcu_print_task_stall(), resulting in an "IRQs not
enabled as expected" diagnostic. This commit therefore updates
try_invoke_on_locked_down_task() to use raw_spin_lock_irqsave() instead
of raw_spin_lock_irq(), thus allowing use from either context.

Some rt tasks undergo sync wakeup. Currently, these tasks will be placed
on other, often sleeping or otherwise idle CPUs, which can lead to
unnecessary power hits.

With DEQUEUE_SAVE and ENQUEUE_RESTORE set when calling deactivate_task
and activate_task, the rt class scheduler will not dequeue/enqueue
the task respectively - move_entity() returns false. This results in
the same task being picked multiple times by __pick_migrate_task,
which results in the same task getting a second initialization of
next->percpu_kthread_node, corrupting the list and causing a crash
with __list_add_valid.
Remove DEQUEUE_SAVE and ENQUEUE_RESTORE when holding back kthreads from
being migrated, for the calls to activate/deactivate task,
preventing the crash.

The current approach to carry the wake_q length is exposed to an
intertask stack access. For example, if A sets the wake_q_head for
B but is preempted before it is able to set it back to NULL,
then B continues to point to an address corresponding to A's stack.
If B is then woken up by another task, it ends up accessing
the address pointing to A's stack. This causes a memory fault.
Replace this with a simple parameter which indicates the number
of tasks that are being woken up as part of the same event. This
avoids saving and accessing on stack pointers.

Asymmetric systems may not offer the same level of userspace ISA support
across all CPUs, meaning that some applications cannot be executed by
some CPUs. As a concrete example, upcoming arm64 big.LITTLE designs do
not feature support for 32-bit applications on both clusters.
Although userspace can carefully manage the affinity masks for such
tasks, one place where it is particularly problematic is execve()
because the CPU on which the execve() is occurring may be incompatible
with the new application image. In such a situation, it is desirable to
restrict the affinity mask of the task and ensure that the new image is
entered on a compatible CPU. From userspace's point of view, this looks
the same as if the incompatible CPUs have been hotplugged off in the
task's affinity mask.
In preparation for restricting the affinity mask for compat tasks on
arm64 systems without uniform support for 32-bit applications, introduce
force_compatible_cpus_allowed_ptr(), which restricts the affinity mask
for a task to contain only compatible CPUs.

Reject explicit requests to change the affinity mask of a task via
set_cpus_allowed_ptr() if the requested mask is not a subset of the
mask returned by task_cpu_possible_mask(). This ensures that the
'cpus_mask' for a given task cannot contain CPUs which are incapable of
executing it, except in cases where the affinity is forced.

across all CPUs, meaning that some applications cannot be executed by
some CPUs. As a concrete example, upcoming arm64 big.LITTLE designs do
not feature support for 32-bit applications on both clusters.
On such a system, we must take care not to migrate a task to an
unsupported CPU when forcefully moving tasks in select_fallback_rq()
in response to a CPU hot-unplug operation.
Introduce a task_cpu_possible_mask() hook which, given a task argument,
allows an architecture to return a cpumask of CPUs that are capable of
executing that task. The default implementation returns the
cpu_possible_mask, since sane machines do not suffer from per-cpu ISA
limitations that affect scheduling. The new mask is used when selecting
the fallback runqueue as a last resort before forcing a migration to the
first active CPU.

The pause feature is designed to keep CPUs idle as
much as possible.
When the timers migration feature is enabled (with
sysctl_timer_migration = 1 ) timer/hrtimer can be
migrated to other CPUs than the CPU currently
queueing the CPU. For example, a pinned kworker
runs on a paused CPU and queued the timer. The
other use case is an interrupt coming on paused CPU
and queueing the time.
Update the get nohz cpu path to use the active
and online masks to prevent paused cpus from
being woken up to queue a timer.
