timers: Reinitialize per cpu bases on hotplug
commit 26456f87aca7157c057de65c9414b37f1ab881d1 upstream.
The timer wheel bases are not (re)initialized on CPU hotplug. That leaves
them with a potentially stale clk and next_expiry valuem, which can cause
trouble then the CPU is plugged.
Add a prepare callback which forwards the clock, sets next_expiry to far in
the future and reset the control flags to a known state.
Set base->must_forward_clk so the first timer which is queued will try to
forward the clock to current jiffies.
Fixes:

smp/hotplug: Replace BUG_ON and react useful
commit dea1d0f5f1284e3defee4b8484d9fc230686cd42 upstream.
The move of the unpark functions to the control thread moved the BUG_ON()
there as well. While it made some sense in the idle thread of the upcoming
CPU, it's bogus to crash the control thread on the already online CPU,
especially as the function has a return value and the callsite is prepared
to handle an error return.
Replace it with a WARN_ON_ONCE() and return a proper error code.

smp/hotplug: Move unparking of percpu threads to the control CPU
commit 9cd4f1a4e7a858849e889a081a99adff83e08e4c upstream.
Vikram reported the following backtrace:
BUG: scheduling while atomic: swapper/7/0/0x00000002
CPU: 7 PID: 0 Comm: swapper/7 Not tainted 4.9.32-perf+ #680
schedule
schedule_hrtimeout_range_clock

wait_task_inactive
__kthread_bind_mask
__kthread_bind
__kthread_unpark
kthread_unpark
cpuhp_online_idle
cpu_startup_entry
secondary_start_kernel
He analyzed correctly that a parked cpu hotplug thread of an offlined CPU
was still on the runqueue when the CPU came back online and tried to unpark
it. This causes the thread which invoked kthread_unpark() to call
wait_task_inactive() and subsequently schedule() with preemption disabled.
His proposed workaround was to "make sure" that a parked thread has
scheduled out when the CPU goes offline, so the situation cannot happen.
But that's still wrong because the root cause is not the fact that the
percpu thread is still on the runqueue and neither that preemption is
disabled, which could be simply solved by enabling preemption before
calling kthread_unpark().
The real issue is that the calling thread is the idle task of the upcoming
CPU, which is not supposed to call anything which might sleep. The moron,
who wrote that code, missed completely that kthread_unpark() might end up
in schedule().
The solution is simpler than expected. The thread which controls the
hotplug operation is waiting for the CPU to call complete() on the hotplug
state completion. So the idle task of the upcoming CPU can set its state to
CPUHP_AP_ONLINE_IDLE and invoke complete(). This in turn wakes the control
task on a different CPU, which then can safely do the unpark and kick the
now unparked hotplug thread of the upcoming CPU to complete the bringup to

smp/hotplug: Move unparking of percpu threads to the control CPU
Vikram reported the following backtrace:
BUG: scheduling while atomic: swapper/7/0/0x00000002
CPU: 7 PID: 0 Comm: swapper/7 Not tainted 4.9.32-perf+ #680
schedule

__kthread_unpark
kthread_unpark
cpuhp_online_idle
cpu_startup_entry
secondary_start_kernel
He analyzed correctly that a parked cpu hotplug thread of an offlined CPU
was still on the runqueue when the CPU came back online and tried to unpark
it. This causes the thread which invoked kthread_unpark() to call
wait_task_inactive() and subsequently schedule() with preemption disabled.
His proposed workaround was to "make sure" that a parked thread has
scheduled out when the CPU goes offline, so the situation cannot happen.
But that's still wrong because the root cause is not the fact that the
percpu thread is still on the runqueue and neither that preemption is
disabled, which could be simply solved by enabling preemption before
calling kthread_unpark().
The real issue is that the calling thread is the idle task of the upcoming
CPU, which is not supposed to call anything which might sleep. The moron,
who wrote that code, missed completely that kthread_unpark() might end up
in schedule().
The solution is simpler than expected. The thread which controls the
hotplug operation is waiting for the CPU to call complete() on the hotplug
state completion. So the idle task of the upcoming CPU can set its state to
CPUHP_AP_ONLINE_IDLE and invoke complete(). This in turn wakes the control
task on a different CPU, which then can safely do the unpark and kick the
now unparked hotplug thread of the upcoming CPU to complete the bringup to
the final target state.

cpu-hotplug: Keep atleast 1 online and un-isolated CPU
The PM_QOS_CPU_DMA_LATENCY vote attached to an IRQ is discarded, if it is affined to an isolated CPU. So we need atleast 1 CPU in online and un-isolate state. The scheduler rejects isolating a CPU if it is the only online and un-isolated CPU in the system. Add the same check for CPU hotplug.

kernel: cpu: send CPU_UP_CANCELLED notifcation
If any of the callbacks during cpu up fail undo_cpu_up calls the teardown call backs to clean up things but does not send CPU_UP_CANCELLED. As some drivers still use the notification mechanism for cpu houplug we need to send CPU_UP_CANCELLED notification so drivers can clean up things they did on cpu up.

kernel: cpu: Handle hotplug failure for state CPUHP_AP_IDLE_DEAD
Once the tear down hotplug handler is run cpu is dead and enters into CPUHP_AP_IDLE_DEAD state. Any callbacks that fail in the state machine with state < CPUHP_AP_IDLE must be treated as fatal. As this could result into timer not beig migrated away from dead cpu and run into issues like work queue lock ups, sched_clock timer wrapping to zero as sched_clock_pll which is in the hrtimer base of cpu being hotplugged does not get migrated.

cpu/hotplug: Drop the device lock on error
commit 40da1b11f01e43aad1aa6cea64681b6125e8a2a7 upstream.
If a custom CPU target is specified and that one is not available _or_
can't be interrupted then the code returns to userland without dropping a
lock as notices by lockdep:
|echo 133 > /sys/devices/system/cpu/cpu7/hotplug/target
| ================================================
| [ BUG: lock held when returning to user space! ]
| ------------------------------------------------
| bash/503 is leaving the kernel with locks still held!
| 1 lock held by bash/503:
| #0: (device_hotplug_lock){+.+...}, at: [<ffffffff815b5650>] lock_device_hotplug_sysfs+0x10/0x40
So release the lock then.

cpu/hotplug: Serialize callback invocations proper
commit dc434e056fe1dada20df7ba07f32739d3a701adf upstream.
The setup/remove_state/instance() functions in the hotplug core code are
serialized against concurrent CPU hotplug, but unfortunately not serialized
against themself.
As a consequence a concurrent invocation of these function results in
corruption of the callback machinery because two instances try to invoke
callbacks on remote cpus at the same time. This results in missing callback
invocations and initiator threads waiting forever on the completion.
The obvious solution to replace get_cpu_online() with cpu_hotplug_begin()
is not possible because at least one callsite calls into these functions
from a get_online_cpu() locked region.
Extend the protection scope of the cpuhp_state_mutex from solely protecting
the state arrays to cover the callback invocation machinery as well.

cpu-hotplug: Always use real time scheduling when hotplugging a CPU
CPU hotplug operations take place in preemptible context. This leaves the hotplugging thread at the mercy of overall system load and CPU availability. If the hotplugging thread does not get an opportunity to execute after it has already begun a hotplug operation, CPUs can end up being stuck in a quasi online state. In the worst case a CPU can be stuck in a state where the migration thread is parked while another task is executing and changing affinity in a loop. This combination can result in unbounded execution time for the running task until the hotplugging thread gets the chance to run to complete the hotplug operation. Fix the said problem by ensuring that hotplug can only occur from threads belonging to the RT sched class. This allows the hotplugging thread priority on the CPU no matter what the system load or the number of available CPUs are. If a SCHED_NORMAL task attempts to hotplug a CPU, we temporarily elevate it's scheduling policy to RT. Furthermore, we disallow hotplugging operations to begin if the calling task belongs to the idle and deadline classes or those that use the SCHED_BATCH policy.

hotplug: Make register and unregister notifier API symmetric
commit 777c6e0daebb3fcefbbd6f620410a946b07ef6d0 upstream.
Yu Zhao has noticed that __unregister_cpu_notifier only unregisters its
notifiers when HOTPLUG_CPU=y while the registration might succeed even
when HOTPLUG_CPU=n if MODULE is enabled. This means that e.g. zswap
might keep a stale notifier on the list on the manual clean up during
the pool tear down and thus corrupt the list. Resulting in the following

cpu/hotplug: Add multi instance support
This patch adds the ability for a given state to have multiple instances. Until now all states have a single instance and the startup / teardown callback use global variables. A few drivers need to perform a the same callbacks on multiple "instances". Currently we have three drivers in tree which all have a global list which they iterate over. With multi instance they support don't need their private list and the functionality has been moved into core code. Plus we hold the hotplug lock in core so no cpus comes/goes while instances are registered and we do rollback in error case :) Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Will Deacon <will.deacon@arm.com> Cc: rt@linutronix.de Link: http://lkml.kernel.org/r/1471024183-12666-3-git-send-email-bigeasy@linutronix.de Signed-off-by: Thomas Gleixner <tglx@linutronix.de> |

cpu/hotplug: Rework callback invocation logic
This is preparation for the following patch. This rework here changes the arguments of cpuhp_invoke_callback(). It passes now `state' and whether `startup' or `teardown' callback should be invoked. The callback then is looked up by the function. The following is a clanup of callers: - cpuhp_issue_call() has one argument less - struct cpuhp_cpu_state (which is used by the hotplug thread) gets also its callback removed. The decision if it is a single callback invocation moved to the `single' variable. Also a `bringup' variable has been added to distinguish between startup and teardown callback. - take_cpu_down() needs to start one step earlier. We always get here via CPUHP_TEARDOWN_CPU callback. Before that change cpuhp_ap_states + CPUHP_TEARDOWN_CPU pointed to an empty entry because TEARDOWN is saved in bp_states for this reason. Now that we use cpuhp_get_step() to lookup the state we must explicitly skip it in order not to invoke it twice.

cpu/hotplug: Allow suspend/resume CPU to be specified
disable_nonboot_cpus() assumes that the lowest numbered online CPU is the boot CPU, and that this is the correct CPU to run any power management code on. On x86 this is always correct, as CPU0 cannot (easily) by taken offline. On arm64 CPU0 can be taken offline. For hibernate/resume this means we may hibernate on a CPU other than CPU0. If the system is rebooted with kexec 'CPU0' will be assigned to a different physical CPU. This complicates hibernate/resume as now we can't trust the CPU numbers. Arch code can find the correct physical CPU, and ensure it is online before resume from hibernate begins, but also needs to influence disable_nonboot_cpus()s choice of CPU. Rename disable_nonboot_cpus() as freeze_secondary_cpus() and add an argument indicating which CPU should be left standing. Follow the logic in migrate_to_reboot_cpu() to use the lowest numbered online CPU if the requested CPU is not online. Add disable_nonboot_cpus() as an inline function that has the existing behaviour.

rcu: Provide exact CPU-online tracking for RCU
Up to now, RCU has assumed that the CPU-online process makes it from CPU_UP_PREPARE to set_cpu_online() within one jiffy. Given the recent rise of virtualized environments, this assumption is very clearly obsolete. Failing to meet this deadline can result in RCU paying attention to an incoming CPU for one jiffy, then ignoring it until the grace period following the one in which that CPU sets itself online. This situation might prove to be fatally disappointing to any RCU read-side critical sections that had the misfortune to execute during the time in which RCU was ignoring the slow-to-come-online CPU. This commit therefore updates RCU's internal CPU state-tracking information at notify_cpu_starting() time, thus providing RCU with an exact transition of the CPU's state from offline to online. Note that this means that incoming CPUs must not use RCU read-side critical section (other than those of SRCU) until notify_cpu_starting() time. Note also that the CPU_STARTING notifiers -are- allowed to use RCU read-side critical sections. (Of course, CPU-hotplug notifiers are rapidly becoming obsolete, so you need to act fast!) If a given architecture or CPU family needs to use RCU read-side critical sections earlier, the call to rcu_cpu_starting() from notify_cpu_starting() will need to be architecture-specific, with architectures that need early use being required to hand-place the call to rcu_cpu_starting() at some point preceding the call to notify_cpu_starting().

timers/core: Correct callback order during CPU hot plug
On the tear-down path, the dead CPU callback for the timers was
misplaced within the 'cpuhp_state' enumeration. There is a hidden
dependency between the timers and block multiqueue. The timers
callback must happen before the block multiqueue callback otherwise a
RCU stall occurs.
Move the timers callback to the proper place in the state machine.
