[PATCH 5/5] sd_zbc: Avoid that resetting a zone fails sporadically

by Bart Van Assche

Since SCSI scanning occurs asynchronously, since sd_revalidate_disk() is called from sd_probe_async() and since sd_revalidate_disk() calls sd_zbc_read_zones() it can happen that sd_zbc_read_zones() is called concurrently with blkdev_report_zones() and/or blkdev_reset_zones(). That can cause these functions to fail with -EIO because sd_zbc_read_zones() e.g. sets q->nr_zones to zero before restoring it to the actual value, even if no drive characteristics have changed. Avoid that this can happen by making the following changes: - Protect the code that updates zone information with blk_queue_enter() and blk_queue_exit(). - Modify sd_zbc_setup_seq_zones_bitmap() and sd_zbc_setup() such that these functions do not modify struct scsi_disk before all zone information has been obtained. Note: since commit 055f6e18e08f ("block: Make q_usage_counter also track legacy requests"; kernel v4.15) the request queue freezing mechanism also affects legacy request queues.

scsi_io_completion() translates the sense key ILLEGAL REQUEST / ASC 0x21 into ACTION_FAIL.

[PATCH 24/24] x86/spectre_v2: Don't check microcode versions when running under hypervisors

by Youquan Song

From: Konrad Rzeszutek Wilk <konrad.wilk(a)oracle.com> (cherry picked from commit 36268223c1e9981d6cfc33aff8520b3bde4b8114) As: 1) It's known that hypervisors lie about the environment anyhow (host mismatch) 2) Even if the hypervisor (Xen, KVM, VMWare, etc) provided a valid "correct" value, it all gets to be very murky when migration happens (do you provide the "new" microcode of the machine?). And in reality the cloud vendors are the ones that should make sure that the microcode that is running is correct and we should just sing lalalala and trust them.

[PATCH 23/23] KVM/VMX: Optimize vmx_vcpu_run() and svm_vcpu_run() by marking the RDMSR path as unlikely()

by Youquan Song

From: Paolo Bonzini <pbonzini(a)redhat.com> commit 946fbbc13dce68902f64515b610eeb2a6c3d7a64 upstream. vmx_vcpu_run() and svm_vcpu_run() are large functions, and giving branch hints to the compiler can actually make a substantial cycle difference by keeping the fast path contiguous in memory. With this optimization, the retpoline-guest/retpoline-host case is about 50 cycles faster.

From: Paolo Bonzini <pbonzini(a)redhat.com> commit ecb586bd29c99fb4de599dec388658e74388daad upstream. Having a paravirt indirect call in the IBRS restore path is not a good idea, since we are trying to protect from speculative execution of bogus indirect branch targets. It is also slower, so use native_wrmsrl() on the vmentry path too.

[PATCH v2 1/2] pinctrl/samsung: Correct EINTG banks order

by Paweł Chmiel

All banks with GPIO interrupts should be at beginning of bank array and without any other types of banks between them. This order is expected by exynos_eint_gpio_irq, when doing interrupt group to bank translation. Otherwise, kernel NULL pointer dereference would happen when trying to handle interrupt, due to wrong bank being looked up. Observed on s5pv210, when trying to handle gpj0 interrupt, where kernel was mapping it to gpi bank.

[PATCH AUTOSEL for 4.15 001/189] firewire-ohci: work around oversized DMA reads on JMicron controllers

by Sasha Levin

From: Hector Martin <marcan(a)marcan.st> [ Upstream commit 188775181bc05f29372b305ef96485840e351fde ] At least some JMicron controllers issue buggy oversized DMA reads when fetching context descriptors, always fetching 0x20 bytes at once for descriptors which are only 0x10 bytes long. This is often harmless, but can cause page faults on modern systems with IOMMUs: DMAR: [DMA Read] Request device [05:00.0] fault addr fff56000 [fault reason 06] PTE Read access is not set firewire_ohci 0000:05:00.0: DMA context IT0 has stopped, error code: evt_descriptor_read This works around the problem by always leaving 0x10 padding bytes at the end of descriptor buffer pages, which should be harmless to do unconditionally for controllers in case others have the same behavior.

kernel panics with 4.14.X versions

by Pavlos Parissis

Hi all, We have observed kernel panics on several master kubernetes clusters, where we run kubernetes API services and not application workloads. Those clusters use kernel version 4.14.14 and 4.14.32, but we switched everything to kernel version 4.14.32 as a way to address the issue. We have HP and Dell hardware on those clusters, and network cards are also different, we have bnx2x and mlx5_core in use. We also run kernel version 4.14.32 on different type of workloads, software load balancing using HAProxy, and we don't have any crashes there. Since the crash happens on different hardware, we think it could be a kernel issue, but we aren't sure about it. Thus, I am contacting kernel people in order to get some hint, which can help us to figure out what causes this. In our kubernetes clusters, we have instructed the kernel to panic upon soft lockup, we use 'kernel.softlockup_panic=1', 'kernel.hung_task_panic=1' and 'kernel.watchdog_thresh=10'. Thus, we see the stack traces. Today, we have disabled this, later I will explain why. I believe we have two discint types of panics, one is trigger upon soft lockup and another one where the call trace is about scheduler("sched: Unexpected reschedule of offline CPU#8!) Let me walk you through the kernel panics and some observations. The followin series of stack traces are happening when one CPU (CPU 24) is stuck for ~22 seconds. watchdog_thresh is set to 10 and as far as I remember softlockup threshold is (2 * watchdog_thresh), so it makes sense to see the kernel crashing after ~20seconds. After the stack trace, we have the output of sar for CPU#24 and we see that just before the crash CPU utilization for system level went to 100%. Now let's move to another panic.

We just need to find out which (kernel/hardware/network driver/userland application) process makes a single CPU to be stuck. Thus, we disabled the trigger to panic the kernel when a soft lockup occurs, and we hope can find out the process. The following panic is from the second type of panics I mentioned, where we don't observe soft lockups and CPU utilization is close to zero before the crash.

The patch below does not apply to the 4.16-stable tree.

Before, to fix erratum AVR31, the following commit: 522e66464467 ("x86/apic: Disable I/O APIC before shutdown of the local APIC") ... moved the lapic_shutdown() call to after disable_IO_APIC() in the reboot and kexec/kdump code paths. This introduced the following regression: disable_IO_APIC() not only clears the IO-APIC, but it also restores boot IRQ mode by setting the LAPIC/APIC/IMCR, calling lapic_shutdown() after disable_IO_APIC() will disable LAPIC and ruin the possible virtual wire mode setting which the code has been trying to do all along. The consequence is that a KVM guest kernel always prints the warning below during kexec/kdump as the kernel boots up: [ 0.001000] WARNING: CPU: 0 PID: 0 at arch/x86/kernel/apic/apic.c:1467 setup_local_APIC+0x228/0x330 [ ........] [ 0.001000] Call Trace: [ 0.001000] apic_bsp_setup+0x56/0x74 [ 0.001000] x86_late_time_init+0x11/0x16 [ 0.001000] start_kernel+0x3c9/0x486 [ 0.001000] secondary_startup_64+0xa5/0xb0 [ ........] [ 0.001000] masked ExtINT on CPU#0 To fix this, just call clear_IO_APIC() to stop the IO-APIC where disable_IO_APIC() was called, and call restore_boot_irq_mode() to restore boot IRQ mode before a reboot or a kexec/kdump jump.

[PATCH V4 2/2] blk-mq: fix race between complete and BLK_EH_RESET_TIMER

by Ming Lei

The normal request completion can be done before or during handling BLK_EH_RESET_TIMER, and this race may cause the request to never be completed since driver's .timeout() may always return BLK_EH_RESET_TIMER. This issue can't be fixed completely by driver, since the normal completion can be done between returning .timeout() and handling BLK_EH_RESET_TIMER. This patch fixes the race by introducing rq state of MQ_RQ_COMPLETE_IN_RESET, and reading/writing rq's state by holding queue lock, which can be per-request actually, but just not necessary to introduce one lock for so unusual event. Also handle the timeout requests in two steps: 1) in 1st step, call .timeout(), and reset timer for BLK_EH_RESET_TIMER 2) in 2nd step, sync with normal completion path by holding queue lock for avoiding race between BLK_EH_RESET_TIMER and normal completion.
