commit 896bbb2522587e3b8eb2a0d204d43ccc1042a00d upstream.
When priority inheritance was added back in 2.6.18 to sched_setscheduler(), it
added a path to taking an rt-mutex wait_lock, which is not IRQ safe. As PI
is not a common occurrence, lockdep will likely never trigger if
sched_setscheduler was called from interrupt context. A BUG_ON() was added
to trigger if __sched_setscheduler() was ever called from interrupt context
because there was a possibility to take the wait_lock.
Today the wait_lock is irq safe, but the path to taking it in
sched_setscheduler() is the same as the path to taking it from normal
context. The wait_lock is taken with raw_spin_lock_irq() and released with
raw_spin_unlock_irq() which will indiscriminately enable interrupts,
which would be bad in interrupt context.
The problem is that normalize_rt_tasks, which is called by triggering the
sysrq nice-all-RT-tasks was changed to call __sched_setscheduler(), and this
is done from interrupt context!
Now __sched_setscheduler() takes a "pi" parameter that is used to know if
the priority inheritance should be called or not. As the BUG_ON() only cares
about calling the PI code, it should only bug if called from interrupt
context with the "pi" parameter set to true.

commit 9bd616e3dbedfc103f158197c8ad93678849b1ed upstream.
The cpuidle_devices per-CPU variable is only defined when CPU_IDLE is
enabled. Commit c8cc7d4de7a4 ("sched/idle: Reorganize the idle loop")
removed the #ifdef CONFIG_CPU_IDLE around cpuidle_idle_call() with the
compiler optimising away __this_cpu_read(cpuidle_devices). However, with
CONFIG_UBSAN && !CONFIG_CPU_IDLE, this optimisation no longer happens
and the kernel fails to link since cpuidle_devices is not defined.
This patch introduces an accessor function for the current CPU cpuidle
device (returning NULL when !CONFIG_CPU_IDLE) and uses it in
cpuidle_idle_call().

commit baa9be4ffb55876923dc9716abc0a448e510ba30 upstream.
With a very low cpu.cfs_quota_us setting, such as the minimum of 1000,
distribute_cfs_runtime may not empty the throttled_list before it runs
out of runtime to distribute. In that case, due to the change from
c06f04c7048 to put throttled entries at the head of the list, later entries
on the list will starve. Essentially, the same X processes will get pulled
off the list, given CPU time and then, when expired, get put back on the
head of the list where distribute_cfs_runtime will give runtime to the same
set of processes leaving the rest.
Fix the issue by setting a bit in struct cfs_bandwidth when
distribute_cfs_runtime is running, so that the code in throttle_cfs_rq can
decide to put the throttled entry on the tail or the head of the list. The
bit is set/cleared by the callers of distribute_cfs_runtime while they hold
cfs_bandwidth->lock.
This is easy to reproduce with a handful of CPU consumers. I use 'crash' on
the live system. In some cases you can simply look at the throttled list and
see the later entries are not changing:
crash> list cfs_rq.throttled_list -H 0xffff90b54f6ade40 -s cfs_rq.runtime_remaining | paste - - | awk '{print $1" "$4}' | pr -t -n3
1 ffff90b56cb2d200 -976050
2 ffff90b56cb2cc00 -484925
3 ffff90b56cb2bc00 -658814
4 ffff90b56cb2ba00 -275365
5 ffff90b166a45600 -135138
6 ffff90b56cb2da00 -282505
7 ffff90b56cb2e000 -148065
8 ffff90b56cb2fa00 -872591
9 ffff90b56cb2c000 -84687
10 ffff90b56cb2f000 -87237
11 ffff90b166a40a00 -164582
crash> list cfs_rq.throttled_list -H 0xffff90b54f6ade40 -s cfs_rq.runtime_remaining | paste - - | awk '{print $1" "$4}' | pr -t -n3
1 ffff90b56cb2d200 -994147
2 ffff90b56cb2cc00 -306051
3 ffff90b56cb2bc00 -961321
4 ffff90b56cb2ba00 -24490
5 ffff90b166a45600 -135138
6 ffff90b56cb2da00 -282505
7 ffff90b56cb2e000 -148065
8 ffff90b56cb2fa00 -872591
9 ffff90b56cb2c000 -84687
10 ffff90b56cb2f000 -87237
11 ffff90b166a40a00 -164582
Sometimes it is easier to see by finding a process getting starved and looking
at the sched_info:
crash> task ffff8eb765994500 sched_info
PID: 7800 TASK: ffff8eb765994500 CPU: 16 COMMAND: "cputest"
sched_info = {
pcount = 8,
run_delay = 697094208,
last_arrival = 240260125039,
last_queued = 240260327513
},
crash> task ffff8eb765994500 sched_info

pcount = 8,

[ Upstream commit 6fe1f348b3dd1f700f9630562b7d38afd6949568 ]
When a cgroup's CPU runqueue is destroyed, it should remove its
remaining load accounting from its parent cgroup.
The current site for doing so it unsuited because its far too late and
unordered against other cgroup removal (->css_free() will be, but we're also
in an RCU callback).
Put it in the ->css_offline() callback, which is the start of cgroup
destruction, right after the group has been made unavailable to
userspace. The ->css_offline() callbacks are called in hierarchical order
after the following v4.4 commit:
aa226ff4a1ce ("cgroup: make sure a parent css isn't offlined before its children")

Every time _cpu_up() is called for a CPU, idle_thread_get() is called
which then re-initializes a CPU's idle thread that was already
previously created and cached in a global variable in
smpboot.c. idle_thread_get() calls init_idle() which then calls
__sched_fork(). __sched_fork() is where cpufreq_task_times_init() is,
and cpufreq_task_times_init() allocates memory for the task struct's
time_in_state array.
Since idle_thread_get() reuses a task struct instance that was already
previously created, this means that every time it calls init_idle(),
cpufreq_task_times_init() allocates this array again and overwrites
the existing allocation that the idle thread already had.
This causes memory to be leaked every time a CPU is onlined. In order
to fix this, move allocation of time_in_state into _do_fork to avoid
allocating it at all for idle threads. The cpufreq times interface is
intended to be used for tracking userspace tasks, so we can safely
remove it from the kernel's idle threads without killing any
functionality.
But that's not all!
Task structs can be freed outside of release_task(), which creates
another memory leak because a task struct can be freed without having
its cpufreq times allocation freed. To fix this, free the cpufreq
times allocation at the same time that task struct allocations are
freed, in free_task().
Since free_task() can also be called in error paths of copy_process()
after dup_task_struct(), set time_in_state to NULL immediately after
calling dup_task_struct() to avoid possible double free.

A computation in update_top_tasks() is indexing
off the end of a top_tasks array. There's code
to limit the index in the computation, but it's
insufficient.

[ Upstream commit d29a20645d5e929aa7e8616f28e5d8e1c49263ec ]
While running rt-tests' pi_stress program I got the following splat:
rq->clock_update_flags < RQCF_ACT_SKIP
WARNING: CPU: 27 PID: 0 at kernel/sched/sched.h:960 assert_clock_updated.isra.38.part.39+0x13/0x20

We can get rid of it be the "traditional" means of adding an
update_rq_clock() call after acquiring the rq->lock in
do_sched_rt_period_timer().
The case for the RT task throttling (which this workload also hits)
can be ignored in that the skip_update call is actually bogus and
quite the contrary (the request bits are removed/reverted).
By setting RQCF_UPDATED we really don't care if the skip is happening
or not and will therefore make the assert_clock_updated() check happy.

capacity_spare_wake in the slow path influences choice of idlest groups,
as we search for groups with maximum spare capacity. In scenarios where
RT pressure is high, a sub optimal group can be chosen and hurt
performance of the task being woken up.
Several tests with results are included below to show improvements with
this change.
1) Hackbench on Pixel 2 Android device (4x4 ARM64 Octa core)
------------------------------------------------------------
Here we have RT activity running on big CPU cluster induced with rt-app,
and running hackbench in parallel. The RT tasks are bound to 4 CPUs on
the big cluster (cpu 4,5,6,7) and have 100ms periodicity with
runtime=20ms sleep=80ms.
Hackbench shows big benefit (30%) improvement when number of tasks is 8
and 32: Note: data is completion time in seconds (lower is better).
Number of loops for 8 and 16 tasks is 50000, and for 32 tasks its 20000.
+--------+-----+-------+-------------------+---------------------------+
| groups | fds | tasks | Without Patch | With Patch |
+--------+-----+-------+---------+---------+-----------------+---------+
| | | | Mean | Stdev | Mean | Stdev |
| | | +-------------------+-----------------+---------+
| 1 | 8 | 8 | 1.0534 | 0.13722 | 0.7293 (+30.7%) | 0.02653 |
| 2 | 8 | 16 | 1.6219 | 0.16631 | 1.6391 (-1%) | 0.24001 |
| 4 | 8 | 32 | 1.2538 | 0.13086 | 1.1080 (+11.6%) | 0.16201 |
+--------+-----+-------+---------+---------+-----------------+---------+
2) Rohit ran barrier.c test (details below) with following improvements:
------------------------------------------------------------------------
This was Rohit's original use case for a patch he posted at [1] however
from his recent tests he showed my patch can replace his slow path
changes [1] and there's no need to selectively scan/skip CPUs in
find_idlest_group_cpu in the slow path to get the improvement he sees.
barrier.c (open_mp code) as a micro-benchmark. It does a number of
iterations and barrier sync at the end of each for loop.
Here barrier,c is running in along with ping on CPU 0 and 1 as:
'ping -l 10000 -q -s 10 -f hostX'
barrier.c can be found at:
http://www.spinics.net/lists/kernel/msg2506955.html
Following are the results for the iterations per second with this
micro-benchmark (higher is better), on a 44 core, 2 socket 88 Threads
Intel x86 machine:
+--------+------------------+---------------------------+
|Threads | Without patch | With patch |
| | | |
+--------+--------+---------+-----------------+---------+
| | Mean | Std Dev | Mean | Std Dev |
+--------+--------+---------+-----------------+---------+
|1 | 539.36 | 60.16 | 572.54 (+6.15%) | 40.95 |
|2 | 481.01 | 19.32 | 530.64 (+10.32%)| 56.16 |
|4 | 474.78 | 22.28 | 479.46 (+0.99%) | 18.89 |
|8 | 450.06 | 24.91 | 447.82 (-0.50%) | 12.36 |
|16 | 436.99 | 22.57 | 441.88 (+1.12%) | 7.39 |
|32 | 388.28 | 55.59 | 429.4 (+10.59%)| 31.14 |
|64 | 314.62 | 6.33 | 311.81 (-0.89%) | 11.99 |
+--------+--------+---------+-----------------+---------+
3) ping+hackbench test on bare-metal sever (Rohit ran this test)
----------------------------------------------------------------
Here hackbench is running in threaded mode along
with, running ping on CPU 0 and 1 as:
'ping -l 10000 -q -s 10 -f hostX'
This test is running on 2 socket, 20 core and 40 threads Intel x86
machine:
Number of loops is 10000 and runtime is in seconds (Lower is better).
+--------------+-----------------+--------------------------+
|Task Groups | Without patch | With patch |
| +-------+---------+----------------+---------+
|(Groups of 40)| Mean | Std Dev | Mean | Std Dev |
+--------------+-------+---------+----------------+---------+
|1 | 0.851 | 0.007 | 0.828 (+2.77%)| 0.032 |
|2 | 1.083 | 0.203 | 1.087 (-0.37%)| 0.246 |
|4 | 1.601 | 0.051 | 1.611 (-0.62%)| 0.055 |
|8 | 2.837 | 0.060 | 2.827 (+0.35%)| 0.031 |
|16 | 5.139 | 0.133 | 5.107 (+0.63%)| 0.085 |
|25 | 7.569 | 0.142 | 7.503 (+0.88%)| 0.143 |
+--------------+-------+---------+----------------+---------+

Matt Fleming also ran cyclictest and several different hackbench tests
on his test machines to santiy-check that the patch doesn't harm any
of his usecases.

commit 4d09122c1868 ("sched: Fix spinlock recursion in sched_exit()")
moved freeing of task's current and previous window arrays outside
the rq->lock. These arrays can be accessed from another CPU in parallel
and end up using freed memory. For example,
CPU#0 CPU#1
---------------------------------- -------------------------------
sched_exit() try_to_wake_up()--> The task wakes
up on CPU#0
task_rq_lock() set_task_cpu()
fixup_busy_time() --> waiting for
CPU#0's rq->lock
task_rq_unlock() fixup_busy_time()-->lock acquired
free_task_load_ptrs()
kfree(p->ravg.curr_window_cpu) update_task_ravg()-->called on
current of CPU#0
trace_sched_update_task_ravg()
--> access freed memory
p->ravg.curr_window_cpu = NULL;
To fix this issue, window array pointers must be set to NULL before
freeing the memory. Since this happens outside the lock, memory barriers
are needed on write and read paths. A much simpler alternative would be
skipping update_task_ravg() trace point for tasks that are marked as dead.
The window stats of dead tasks are not updated any ways. While at it, skip
this trace point for newly created tasks for which also window stats are
not updated.

[ Upstream commit 8655d5497735b288f8a9b458bd22e7d1bf95bb61 ]
A customer has reported a soft-lockup when running an intensive
memory stress test, where the trace on multiple CPU's looks like this:
RIP: 0010:[<ffffffff810c53fe>]
[<ffffffff810c53fe>] native_queued_spin_lock_slowpath+0x10e/0x190
...
Call Trace:
[<ffffffff81182d07>] queued_spin_lock_slowpath+0x7/0xa
[<ffffffff811bc331>] change_protection_range+0x3b1/0x930
[<ffffffff811d4be8>] change_prot_numa+0x18/0x30
[<ffffffff810adefe>] task_numa_work+0x1fe/0x310
[<ffffffff81098322>] task_work_run+0x72/0x90
Further investigation showed that the lock contention here is pmd_lock().
The task_numa_work() function makes sure that only one thread is let to perform
the work in a single scan period (via cmpxchg), but if there's a thread with
mmap_sem locked for writing for several periods, multiple threads in
task_numa_work() can build up a convoy waiting for mmap_sem for read and then
all get unblocked at once.
This patch changes the down_read() to the trylock version, which prevents the
build up. For a workload experiencing mmap_sem contention, it's probably better
to postpone the NUMA balancing work anyway. This seems to have fixed the soft
lockups involving pmd_lock(), which is in line with the convoy theory.

This splat cannot be generated by expedited grace periods because they
always invoke resched_cpu() on the current CPU, which is good because
expedited grace periods require that resched_cpu() unconditionally
succeed. However, other parts of RCU can tolerate resched_cpu() acting
as a no-op, at least as long as it doesn't happen too often.
This commit therefore makes resched_cpu() invoke resched_curr() only if
the CPU is either online or is the current CPU.

[ Upstream commit 2fe2582649aa2355f79acddb86bd4d6c5363eb63 ]
The rcutorture test suite occasionally provokes a splat due to invoking
rt_mutex_lock() which needs to boost the priority of a task currently
sitting on a runqueue that belongs to an offline CPU:

But the target task's priority has already been adjusted, so the only
purpose of switched_to_rt() invoking resched_curr() is to wake up the
CPU running some task that needs to be preempted by the boosted task.
But the CPU is offline, which presumably means that the task must be
migrated to some other CPU, and that this other CPU will undertake any
needed preemption at the time of migration. Because the runqueue lock
is held when resched_curr() is invoked, we know that the boosted task
cannot go anywhere, so it is not necessary to invoke resched_curr()
in this particular case.
This commit therefore makes switched_to_rt() refrain from invoking
resched_curr() when the target CPU is offline.

sched_get_cpu_last_busy_time() returns the last time stamp when
a given CPU is busy with more than 2 runnable tasks or has load
greater than 50% of it's max capacity. The LPM driver can make
use of this API and create a policy to prevent a recently loaded
CPU entering deep sleep state.
This API is implemented only for the higher capacity CPUs in
the system. It returns 0 for other CPUs.

commit 364f56653708ba8bcdefd4f0da2a42904baa8eeb upstream.
When issuing an IPI RT push, where an IPI is sent to each CPU that has more
than one RT task scheduled on it, it references the root domain's rto_mask,
that contains all the CPUs within the root domain that has more than one RT
task in the runable state. The problem is, after the IPIs are initiated, the
rq->lock is released. This means that the root domain that is associated to
the run queue could be freed while the IPIs are going around.
Add a sched_get_rd() and a sched_put_rd() that will increment and decrement
the root domain's ref count respectively. This way when initiating the IPIs,
the scheduler will up the root domain's ref count before releasing the
rq->lock, ensuring that the root domain does not go away until the IPI round
is complete.

commit ad0f1d9d65938aec72a698116cd73a980916895e upstream.
When the rto_push_irq_work_func() is called, it looks at the RT overloaded
bitmask in the root domain via the runqueue (rq->rd). The problem is that
during CPU up and down, nothing here stops rq->rd from changing between
taking the rq->rd->rto_lock and releasing it. That means the lock that is
released is not the same lock that was taken.
Instead of using this_rq()->rd to get the root domain, as the irq work is
part of the root domain, we can simply get the root domain from the irq work
that is passed to the routine:
container_of(work, struct root_domain, rto_push_work)
This keeps the root domain consistent.

There is a race between hotplug and energy_diff which might result
in endless loop in sched_group_energy. When this happens, the end
condition cannot be detected.
We can store how many CPUs we need to visit at the beginning, and
bail out of the energy calculation if we visit more cpus than expected.

Boosted RT tasks can be deboosted quickly, this makes boost usless
for RT tasks and causes lots of glitching. Use timers to prevent
de-boost too soon and wait for long enough such that next enqueue
happens after a threshold.
While this can be solved in the governor, there are following
advantages:
- The approach used is governor-independent
- Reduces boost group lock contention for frequently sleepers/wakers
Note:
Fixed build breakage due to schedfreq dependency which isn't used
for RT anymore.

commit 3effcb4247e74a51f5d8b775a1ee4abf87cc089a upstream.
We have been facing some problems with self-suspending constrained
deadline tasks. The main reason is that the original CBS was not
designed for such sort of tasks.
One problem reported by Xunlei Pang takes place when a task
suspends, and then is awakened before the deadline, but so close
to the deadline that its remaining runtime can cause the task
to have an absolute density higher than allowed. In such situation,
the original CBS assumes that the task is facing an early activation,
and so it replenishes the task and set another deadline, one deadline
in the future. This rule works fine for implicit deadline tasks.
Moreover, it allows the system to adapt the period of a task in which
the external event source suffered from a clock drift.
However, this opens the window for bandwidth leakage for constrained
deadline tasks. For instance, a task with the following parameters:
runtime = 5 ms
deadline = 7 ms
[density] = 5 / 7 = 0.71
period = 1000 ms
If the task runs for 1 ms, and then suspends for another 1ms,
it will be awakened with the following parameters:
remaining runtime = 4
laxity = 5
presenting a absolute density of 4 / 5 = 0.80.
In this case, the original CBS would assume the task had an early
wakeup. Then, CBS will reset the runtime, and the absolute deadline will
be postponed by one relative deadline, allowing the task to run.
The problem is that, if the task runs this pattern forever, it will keep
receiving bandwidth, being able to run 1ms every 2ms. Following this
behavior, the task would be able to run 500 ms in 1 sec. Thus running
more than the 5 ms / 1 sec the admission control allowed it to run.
Trying to address the self-suspending case, Luca Abeni, Giuseppe
Lipari, and Juri Lelli [1] revisited the CBS in order to deal with
self-suspending tasks. In the new approach, rather than
replenishing/postponing the absolute deadline, the revised wakeup rule
adjusts the remaining runtime, reducing it to fit into the allowed
density.
A revised version of the idea is:
At a given time t, the maximum absolute density of a task cannot be
higher than its relative density, that is:
runtime / (deadline - t) <= dl_runtime / dl_deadline
Knowing the laxity of a task (deadline - t), it is possible to move
it to the other side of the equality, thus enabling to define max
remaining runtime a task can use within the absolute deadline, without
over-running the allowed density:
runtime = (dl_runtime / dl_deadline) * (deadline - t)
For instance, in our previous example, the task could still run:
runtime = ( 5 / 7 ) * 5
runtime = 3.57 ms
Without causing damage for other deadline tasks. It is note worthy
that the laxity cannot be negative because that would cause a negative
runtime. Thus, this patch depends on the patch:
df8eac8cafce ("sched/deadline: Throttle a constrained deadline task activated after the deadline")
Which throttles a constrained deadline task activated after the
deadline.
Finally, it is also possible to use the revised wakeup rule for
all other tasks, but that would require some more discussions
about pros and cons.
[The main difference from the original commit is that
the BW_SHIFT define was not present yet. As BW_SHIFT was
introduced in a new feature, I just used the value (20),
likewise we used to use before the #define.
Other changes were required because of comments. - bistrot]

select_energy_cpu_brute() in up-migrate path
In up-migrate path, select_energy_cpu_brute() was called directly
without checking energy_aware(). This will make select_energy_cpu_brute()
always worked even disabling energy_aware() on the asymmetric cpu
capacity system.

commit ae83b56a56f8d9643dedbee86b457fa1c5d42f59 upstream.
When a contrained task is throttled by dl_check_constrained_dl(),
it may carry the remaining positive runtime, as a result when
dl_task_timer() fires and calls replenish_dl_entity(), it will
not be replenished correctly due to the positive dl_se->runtime.
This patch assigns its runtime to 0 if positive after throttling.

For the first type crash, the root cause is the push_task pointer will be
used without initialization on the out_lock path. And maybe cpu hotplug in/out
make this happen more easily.
For the second type crash, it hits 'BUG_ON(td->cpu != smp_processor_id());' in
smpboot_thread_fn(). It seems that OOPS was caused by migration/2 which actually
running on cpu1. And I haven't found what actually happened.
However, after this fix, the second type crash seems gone too.
