[ Upstream commit f95091536f78971b269ec321b057b8d630b0ad8a ]

It is possible for sched_getattr() to incorrectly report the state of the reset_on_fork flag when called on a deadline task.

Indeed, if the flag was set on a deadline task using sched_setattr() with flags (SCHED_FLAG_RESET_ON_FORK | SCHED_FLAG_KEEP_PARAMS), then p->sched_reset_on_fork will be set, but __setscheduler() will bail out early, which means that the dl_se->flags will not get updated by __setscheduler_params()->__setparam_dl(). Consequently, if sched_getattr() is then called on the task, __getparam_dl() will override kattr.sched_flags with the now out-of-date copy in dl_se->flags and report the stale value to userspace.

To fix this, make sure to only copy the flags that are relevant to sched_deadline to and from the dl_se->flags field.

We should not clear FLAGS_DMA_ACTIVE before omap_sham_update_dma_stop() is done calling dma_unmap_sg(). We already clear FLAGS_DMA_ACTIVE at the end of omap_sham_update_dma_stop().

The early clearing of FLAGS_DMA_ACTIVE is not causing issues as we do not need to defer anything based on FLAGS_DMA_ACTIVE currently. So this can be applied as clean-up.

[ Upstream commit ccfc9dd6914feaa9a81f10f9cce56eb0f7712264 ]

The soft watchdog timer function checks if a virtual machine was suspended and hence what looks like a lockup in fact is a false positive.

This is what kvm_check_and_clear_guest_paused() does: it tests guest PVCLOCK_GUEST_STOPPED (which is set by the host) and if it's set then we need to touch all watchdogs and bail out.

Watchdog timer function runs from IRQ, so PVCLOCK_GUEST_STOPPED check works fine.

There is, however, one more watchdog that runs from IRQ, so watchdog timer fn races with it, and that watchdog is not aware of PVCLOCK_GUEST_STOPPED - RCU stall detector.

apic_timer_interrupt() smp_apic_timer_interrupt() hrtimer_interrupt() __hrtimer_run_queues() tick_sched_timer() tick_sched_handle() update_process_times() rcu_sched_clock_irq()

This triggers RCU stalls on our devices during VM resume.

If tick_sched_handle()->rcu_sched_clock_irq() runs on a VCPU before watchdog_timer_fn()->kvm_check_and_clear_guest_paused() then there is nothing on this VCPU that touches watchdogs and RCU reads stale gp stall timestamp and new jiffies value, which makes it think that RCU has stalled.

Make RCU stall watchdog aware of PVCLOCK_GUEST_STOPPED and don't report RCU stalls when we resume the VM.

[ Upstream commit 406dd42bd1ba0c01babf9cde169bb319e52f6147 ]

When an itimer deactivates a previously armed expiration, it simply doesn't do anything. As a result the process wide cputime counter keeps running and the tick dependency stays set until it reaches the old ghost expiration value.

This can be reproduced with the following snippet:

void trigger_process_counter(void) { struct itimerval n = {};

n.it_value.tv_sec = 100; setitimer(ITIMER_VIRTUAL, &n, NULL); n.it_value.tv_sec = 0; setitimer(ITIMER_VIRTUAL, &n, NULL); }

Fix this with resetting the relevant base expiration. This is similar to disarming a timer.

Currently iocharset=utf8 mount option is broken. To use UTF-8 as iocharset, it is required to use utf8 mount option.

Fix iocharset=utf8 mount option to use be equivalent to the utf8 mount option.

If UTF-8 as iocharset is used then s_nls_map is set to NULL. So simplify code around, remove UDF_FLAG_NLS_MAP and UDF_FLAG_UTF8 flags as to distinguish between UTF-8 and non-UTF-8 it is needed just to check if s_nls_map set to NULL or not.

Tests showed a mismatch between what the CCA tool reports about the APKA master key state and what's displayed by the zcrypt dd in sysfs. After some investigation, we found out that the documentation which was the source for the zcrypt dd implementation lacks the listing of 3 fields. So this patch now moves the evaluation of the APKA master key state to the correct offset.

Fix this by using spin_{,un}lock_bh() around device list access in all the probe and remove functions.

The top half of the VF drivers handled only a source at the time. If an interrupt for PF2VF and bundle occurred at the same time, the ISR scheduled only the bottom half for PF2VF. This patch fixes the VF top half so that if both sources of interrupt trigger at the same time, both bottom halves are scheduled.

This patch is based on earlier work done by Conor McLoughlin.

At start and shutdown, VFs notify the PF about their state. These notifications are carried out through a message exchange using the PFVF protocol.

Function names lead to believe they do perform init or shutdown logic. This is to fix the naming to better reflect their purpose.

[ Upstream commit 2f488f698fda820f8e6fa0407630154eceb145d6 ]

There is an existing lock hierarchy of &dev->event_lock --> &fasync_struct.fa_lock --> &f->f_owner.lock from the following call chain:

input_inject_event(): spin_lock_irqsave(&dev->event_lock,...); input_handle_event(): input_pass_values(): input_to_handler(): evdev_events(): evdev_pass_values(): spin_lock(&client->buffer_lock); __pass_event(): kill_fasync(): kill_fasync_rcu(): read_lock(&fa->fa_lock); send_sigio(): read_lock_irqsave(&fown->lock,...);

&dev->event_lock is HARDIRQ-safe, so interrupts have to be disabled while grabbing &fasync_struct.fa_lock, otherwise we invert the lock hierarchy. However, since kill_fasync which calls kill_fasync_rcu is an exported symbol, it may not necessarily be called with interrupts disabled.

As kill_fasync_rcu may be called with interrupts disabled (for example, in the call chain above), we replace calls to read_lock/read_unlock on &fasync_struct.fa_lock in kill_fasync_rcu with read_lock_irqsave/read_unlock_irqrestore.

Any previously recorded s390dbf debug data is reset when a debug area is resized using the 'pages' sysfs attribute. This can make live-debugging unnecessarily complex.

Fix this by copying existing debug data to the newly allocated debug area when resizing.

[ Upstream commit cabebb697c98fb1f05cc950a747a9b6ec61a5b01 ]

If for any reason the interrupt enable for an ap queue fails the state machine run for the queue returned wrong return codes to the caller. So the caller assumed interrupt support for this queue in enabled and thus did not re-establish the high resolution timer used for polling. In the end this let to a hang for the user space process waiting "forever" for the reply.

This patch reworks these return codes to return correct indications for the caller to re-establish the timer when a queue runs without interrupt support.

Please note that this is fixing a wrong behavior after a first failure (enable interrupt support for the queue) failed. However, looks like this occasionally happens on KVM systems.
