Geert Uytterhoeven	a892d74963	cpu/speculation: Warn on unsupported mitigations= parameter ... commit 1bf72720281770162c87990697eae1ba2f1d917a upstream. Currently, if the user specifies an unsupported mitigation strategy on the kernel command line, it will be ignored silently. The code will fall back to the default strategy, possibly leaving the system more vulnerable than expected. This may happen due to e.g. a simple typo, or, for a stable kernel release, because not all mitigation strategies have been backported. Inform the user by printing a message.

Josh Poimboeuf	31a2c5f7a2	cpu/speculation: Add 'mitigations=' cmdline option ... commit 98af8452945c55652de68536afdde3b520fec429 upstream. Keeping track of the number of mitigations for all the CPU speculation bugs has become overwhelming for many users. It's getting more and more complicated to decide which mitigations are needed for a given architecture. Complicating matters is the fact that each arch tends to have its own custom way to mitigate the same vulnerability. Most users fall into a few basic categories: a) they want all mitigations off; b) they want all reasonable mitigations on, with SMT enabled even if it's vulnerable; or c) they want all reasonable mitigations on, with SMT disabled if vulnerable. Define a set of curated, arch-independent options, each of which is an aggregation of existing options: - mitigations=off: Disable all mitigations. - mitigations=auto: [default] Enable all the default mitigations, but leave SMT enabled, even if it's vulnerable. - mitigations=auto,nosmt: Enable all the default mitigations, disabling SMT if needed by a mitigation.

Thomas Gleixner	892d9881b4	x86/speculation: Rework SMT state change ... commit a74cfffb03b73d41e08f84c2e5c87dec0ce3db9f upstream. arch_smt_update() is only called when the sysfs SMT control knob is changed. This means that when SMT is enabled in the sysfs control knob the system is considered to have SMT active even if all siblings are offline. To allow finegrained control of the speculation mitigations, the actual SMT state is more interesting than the fact that siblings could be enabled. Rework the code, so arch_smt_update() is invoked from each individual CPU hotplug function, and simplify the update function while at it.

Syed Rameez Mustafa	cbc3fee7f7	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.

Arnd Bergmann	56ef587b77	stable-fixup: hotplug: fix unused function warning ... [resolves a messed up backport, so no matching upstream commit] The backport of upstream commit 777c6e0daebb ("hotplug: Make register and unregister notifier API symmetric") to linux-4.4.y introduced a harmless warning in 'allnoconfig' builds as spotted by kernelci.org: kernel/cpu.c:226:13: warning: 'cpu_notify_nofail' defined but not used [-Wunused-function] So far, this is the only stable tree that is affected, as linux-4.6 and higher contain commit 984581728eb4 ("cpu/hotplug: Split out cpu down functions") that makes the function used in all configurations, while older longterm releases so far don't seem to have a backport of 777c6e0daebb. The fix for the warning is trivial: move the unused function back into the #ifdef section where it was before.

Michal Hocko	1c0f4e0ebb	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 [ 144.964346] BUG: unable to handle kernel paging request at ffff880658a2be78 [ 144.971337] IP: [<ffffffffa290b00b>] raw_notifier_chain_register+0x1b/0x40 <snipped> [ 145.122628] Call Trace: [ 145.125086] [<ffffffffa28e5cf8>] __register_cpu_notifier+0x18/0x20 [ 145.131350] [<ffffffffa2a5dd73>] zswap_pool_create+0x273/0x400 [ 145.137268] [<ffffffffa2a5e0fc>] __zswap_param_set+0x1fc/0x300 [ 145.143188] [<ffffffffa2944c1d>] ? trace_hardirqs_on+0xd/0x10 [ 145.149018] [<ffffffffa2908798>] ? kernel_param_lock+0x28/0x30 [ 145.154940] [<ffffffffa2a3e8cf>] ? __might_fault+0x4f/0xa0 [ 145.160511] [<ffffffffa2a5e237>] zswap_compressor_param_set+0x17/0x20 [ 145.167035] [<ffffffffa2908d3c>] param_attr_store+0x5c/0xb0 [ 145.172694] [<ffffffffa290848d>] module_attr_store+0x1d/0x30 [ 145.178443] [<ffffffffa2b2b41f>] sysfs_kf_write+0x4f/0x70 [ 145.183925] [<ffffffffa2b2a5b9>] kernfs_fop_write+0x149/0x180 [ 145.189761] [<ffffffffa2a99248>] __vfs_write+0x18/0x40 [ 145.194982] [<ffffffffa2a9a412>] vfs_write+0xb2/0x1a0 [ 145.200122] [<ffffffffa2a9a732>] SyS_write+0x52/0xa0 [ 145.205177] [<ffffffffa2ff4d97>] entry_SYSCALL_64_fastpath+0x12/0x17 This can be even triggered manually by changing /sys/module/zswap/parameters/compressor multiple times.

(cherry picked from commit 01b41159066531cc8d664362ff0cd89dd137bbfa) When cpu_hotplug_enable() is called unbalanced w/o a preceeding cpu_hotplug_disable() the code emits a warning, but happily decrements the disabled counter. This causes the next operations to malfunction. Prevent the decrement and just emit a warning.

Oleg Nesterov	c00166d87e	stop_machine: Kill smp_hotplug_thread->pre_unpark, introduce stop_machine_unpark() ... 1. Change smpboot_unpark_thread() to check ->selfparking, just like smpboot_park_thread() does. 2. Introduce stop_machine_unpark() which sets ->enabled and calls kthread_unpark(). 3. Change smpboot_thread_call() and cpu_stop_init() to call stop_machine_unpark() by hand. This way: - IMO the ->selfparking logic becomes more consistent. - We can kill the smp_hotplug_thread->pre_unpark() method. - We can easily unpark the stopper thread earlier. Say, we can move stop_machine_unpark() from smpboot_thread_call() to sched_cpu_active() as Peter suggests.

Oleg Nesterov	233e7f267e	stop_machine: Ensure that a queued callback will be called before cpu_stop_park() ... cpu_stop_queue_work() checks stopper->enabled before it queues the work, but ->enabled == T can only guarantee cpu_stop_signal_done() if we race with cpu_down(). This is not enough for stop_two_cpus() or stop_machine(), they will deadlock if multi_cpu_stop() won't be called by one of the target CPU's. stop_machine/stop_cpus are fine, they rely on stop_cpus_mutex. But stop_two_cpus() has to check cpu_active() to avoid the same race with hotplug, and this check is very unobvious and probably not even correct if we race with cpu_up(). Change cpu_down() pass to clear ->enabled before cpu_stopper_thread() flushes the pending ->works and returns with KTHREAD_SHOULD_PARK set. Note also that smpboot_thread_call() calls cpu_stop_unpark() which sets enabled == T at CPU_ONLINE stage, so this CPU can't go away until cpu_stopper_thread() is called at least once. This all means that if cpu_stop_queue_work() succeeds, we know that work->fn() will be called.

Vitaly Kuznetsov	89af7ba574	cpu-hotplug: convert cpu_hotplug_disabled to a counter ... As a prerequisite to exporting cpu_hotplug_enable/cpu_hotplug_disable functions to modules we need to convert cpu_hotplug_disabled to a counter to properly support disable -> disable -> enable call sequences. E.g. after Hyper-V vmbus module (which is supposed to be the first user of exported cpu_hotplug_enable/cpu_hotplug_disable) did cpu_hotplug_disable() hibernate path calls disable_nonboot_cpus() and if we hit an error in _cpu_down() enable_nonboot_cpus() will be called on the failure path (thus making cpu_hotplug_disabled = 0 and leaving cpu hotplug in 'enabled' state). Same problem is possible if more than 1 module use cpu_hotplug_disable/cpu_hotplug_enable on their load/unload paths. When one of these modules is been unloaded it is logical to leave cpu hotplug in 'disabled' state. To support the change we need to increse cpu_hotplug_disabled counter in disable_nonboot_cpus() unconditionally as all users of disable_nonboot_cpus() are supposed to do enable_nonboot_cpus() in case an error was returned.

Thomas Gleixner	ce0d3c0a6f	genirq: Revert sparse irq locking around __cpu_up() and move it to x86 for now ... Boris reported that the sparse_irq protection around __cpu_up() in the generic code causes a regression on Xen. Xen allocates interrupts and some more in the xen_cpu_up() function, so it deadlocks on the sparse_irq_lock. There is no simple fix for this and we really should have the protection for all architectures, but for now the only solution is to move it to x86 where actual wreckage due to the lack of protection has been observed.

Thomas Gleixner	a899418167	hotplug: Prevent alloc/free of irq descriptors during cpu up/down ... When a cpu goes up some architectures (e.g. x86) have to walk the irq space to set up the vector space for the cpu. While this needs extra protection at the architecture level we can avoid a few race conditions by preventing the concurrent allocation/free of irq descriptors and the associated data. When a cpu goes down it moves the interrupts which are targeted to this cpu away by reassigning the affinities. While this happens interrupts can be allocated and freed, which opens a can of race conditions in the code which reassignes the affinities because interrupt descriptors might be freed underneath. Example: CPU1 CPU2 cpu_up/down irq_desc = irq_to_desc(irq); remove_from_radix_tree(desc); raw_spin_lock(&desc->lock); free(desc); We could protect the irq descriptors with RCU, but that would require a full tree change of all accesses to interrupt descriptors. But fortunately these kind of race conditions are rather limited to a few things like cpu hotplug. The normal setup/teardown is very well serialized. So the simpler and obvious solution is: Prevent allocation and freeing of interrupt descriptors accross cpu hotplug.

Preeti U Murthy	345527b1ed	clockevents: Fix cpu_down() race for hrtimer based broadcasting ... It was found when doing a hotplug stress test on POWER, that the machine either hit softlockups or rcu_sched stall warnings. The issue was traced to commit: 7cba160ad7 ("powernv/cpuidle: Redesign idle states management") which exposed the cpu_down() race with hrtimer based broadcast mode: 5d1638acb9 ("tick: Introduce hrtimer based broadcast") The race is the following: Assume CPU1 is the CPU which holds the hrtimer broadcasting duty before it is taken down. CPU0 CPU1 cpu_down() take_cpu_down() disable_interrupts() cpu_die() while (CPU1 != CPU_DEAD) { msleep(100); switch_to_idle(); stop_cpu_timer(); schedule_broadcast(); } tick_cleanup_cpu_dead() take_over_broadcast() So after CPU1 disabled interrupts it cannot handle the broadcast hrtimer anymore, so CPU0 will be stuck forever. Fix this by explicitly taking over broadcast duty before cpu_die(). This is a temporary workaround. What we really want is a callback in the clockevent device which allows us to do that from the dying CPU by pushing the hrtimer onto a different cpu. That might involve an IPI and is definitely more complex than this immediate fix.

E.g.: for i in `seq 5000`; do echo 1 > /sys/devices/system/cpu/cpu1/online echo 0 > /sys/devices/system/cpu/cpu1/online done Will result in: INFO: task /cpu_start_stop:1 blocked for more than 120 seconds.

And a deadlock. Problem is that if the last ref in put_online_cpus() can't get the cpu_hotplug.lock the puts_pending count is incremented, but a sleeping active_writer might never be woken up, therefore never exiting the loop in cpu_hotplug_begin(). This fix removes puts_pending and turns refcount into an atomic variable. We also introduce a wait queue for the active_writer, to avoid possible races and use-after-free. There is no need to take the lock in put_online_cpus() anymore. Can't reproduce it with this fix. Signed-off-by: David Hildenbrand <dahi@linux.vnet.ibm.com> Signed-off-by: Paul E.
