Recent discard changes meant that REQ_DISCARD bios are processed with a migration. Discards are not background IO so nr_migrations was not incremented. However this could cause quiescing to complete early. (i) is now handled with a new variable cache->nr_allocated_migrations. cache->nr_migrations has been renamed cache->nr_io_migrations. cleanup_migration() is now called free_io_migration(), since it decrements that variable. Also, remove the unused cache->next_migration variable that got replaced with with prealloc_structs a while ago.

9b1cc9f | Joe Thornber | 23 January 2015, 10:00:07 UTC | dm cache: share cache-metadata object across inactive and active DM tables If a DM table is reloaded with an inactive table when the device is not suspended (normal procedure for LVM2), then there will be two dm-bufio objects that can diverge. This can lead to a situation where the inactive table uses bufio to read metadata at the same time the active table writes metadata -- resulting in the inactive table having stale metadata buffers once it is promoted to the active table slot. Fix this by using reference counting and a global list of cache metadata objects to ensure there is only one metadata object per metadata device.

This effectively prevents PCI_MSI support on 32bit UP systems because it disables both APIC and IO-APIC. But APIC support is architecturally required for PCI_MSI. The intention of the patch was to enforce APIC support when PCI_MSI is enabled, but failed to do so. Remove the !PCI_MSI dependency from X86_UP_APIC and enforce X86_UP_APIC when PCI_MSI support is enabled on 32bit UP systems.

3669ef9 | Andy Lutomirski | 22 January 2015, 19:27:59 UTC | x86, tls: Interpret an all-zero struct user_desc as "no segment" The Witcher 2 did something like this to allocate a TLS segment index: struct user_desc u_info; bzero(&u_info, sizeof(u_info)); u_info.entry_number = (uint32_t)-1; syscall(SYS_set_thread_area, &u_info); Strictly speaking, this code was never correct. It should have set read_exec_only and seg_not_present to 1 to indicate that it wanted to find a free slot without putting anything there, or it should have put something sensible in the TLS slot if it wanted to allocate a TLS entry for real. The actual effect of this code was to allocate a bogus segment that could be used to exploit espfix. The set_thread_area hardening patches changed the behavior, causing set_thread_area to return -EINVAL and crashing the game. This changes set_thread_area to interpret this as a request to find a free slot and to leave it empty, which isn't *quite* what the game expects but should be close enough to keep it working. In particular, using the code above to allocate two segments will allocate the same segment both times. According to FrostbittenKing on Github, this fixes The Witcher 2. If this somehow still causes problems, we could instead allocate a limit==0 32-bit data segment, but that seems rather ugly to me.

He suggested an identical patch to one I had already coded up and tested. commit fe3d197f8431 "x86, mpx: On-demand kernel allocation of bounds tables" added two new prctl() operations, PR_MPX_ENABLE_MANAGEMENT and PR_MPX_DISABLE_MANAGEMENT. However, no checks were included to ensure that unused arguments are zero, as is done in many existing prctl()s and as should be done for all new prctl()s. This patch adds the required checks.

c922228 | Dave Hansen | 08 January 2015, 22:30:21 UTC | x86, mpx: Fix potential performance issue on unmaps The 3.19 merge window saw some TLB modifications merged which caused a performance regression. They were fixed in commit 045bbb9fa. Once that fix was applied, I also noticed that there was a small but intermittent regression still present. It was not present consistently enough to bisect reliably, but I'm fairly confident that it came from (my own) MPX patches. The source was reading a relatively unused field in the mm_struct via arch_unmap. I also noted that this code was in the main instruction flow of do_munmap() and probably had more icache impact than we want. This patch does two things: 1. Adds a static (via Kconfig) and dynamic (via cpuid) check for MPX with cpu_feature_enabled(). This keeps us from reading that cacheline in the mm and trades it for a check of the global CPUID variables at least on CPUs without MPX. 2. Adds an unlikely() to ensure that the MPX call ends up out of the main instruction flow in do_munmap(). I've added a detailed comment about why this was done and why we want it even on systems where MPX is present.

814564a | Dave Hansen | 08 January 2015, 22:30:20 UTC | x86, mpx: Explicitly disable 32-bit MPX support on 64-bit kernels We had originally planned on submitting MPX support in one patch set. We eventually broke it up in to two pieces for easier review. One of the features that didn't make the first round was supporting 32-bit binaries on 64-bit kernels. Once we split the set up, we never added code to restrict 32-bit binaries from _using_ MPX on 64-bit kernels. The 32-bit bounds tables are a different format than the 64-bit ones. Without this patch, the kernel will try to read a 32-bit binary's tables as if they were the 64-bit version. They will likely be noticed as being invalid rather quickly and the app will get killed, but that's kinda mean. This patch adds an explicit check, and will make a 64-bit kernel essentially behave as if it has no MPX support when called from a 32-bit binary.

6cf11ee | Hans Verkuil | 19 January 2015, 09:16:18 UTC | [media] vb2: fix vb2_thread_stop race conditions The locking scheme inside the vb2 thread is unsafe when stopping the thread. In particular kthread_stop was called *after* internal data structures were cleaned up instead of doing that before. In addition, internal vb2 functions were called after threadio->stop was set to true and vb2_internal_streamoff was called. This is also not allowed. All this led to a variety of race conditions and kernel warnings and/or oopses. Fixed by moving the kthread_stop call up before the cleanup takes place, and by checking threadio->stop before calling internal vb2 queuing operations.

I didn't think this could have been from workqueue side because no one else was reporting it. This time, Eric had a kdump which we looked into and it turned out this actually was a workqueue bug and the bug has been there since the beginning of concurrency managed workqueue. A worker pool ensures forward progress of the workqueues associated with it by always having at least one worker reserved from executing work items. When the pool is under contention, the idle one tries to create more workers for the pool and if that doesn't succeed quickly enough, it calls the rescuers to the pool. This logic had a subtle race condition in an early exit path. When a worker invokes this manager function, the function may return %false indicating that the caller may proceed to executing work items either because another worker is already performing the role or conditions have changed and the pool is no longer under contention. The latter part depended on the assumption that whether more workers are necessary or not remains stable while the pool is locked; however, pool->nr_running (concurrency count) may change asynchronously and it getting bumped from zero asynchronously could send off the last idle worker to execute work items. The race window is fairly narrow, and, even when it gets triggered, the pool deadlocks iff if all work items get blocked on pending work items of the pool, which is highly unlikely but can be triggered by xfs. The patch removes the race window by removing the early exit path, which doesn't server any purpose anymore anyway" * 'for-3.19-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: fix subtle pool management issue which can stall whole worker_pool | 20 January 2015, 19:51:46 UTC |

Once it is called during suspending state and explicitly before rtsx_usb_suspend() acquires the same dev_mutex, both routine deadlock and further hang the driver because pm_runtime_get_sync() waits the pending PM operations.

b568b86 | Jiang Liu | 20 January 2015, 02:21:05 UTC | x86/xen: Treat SCI interrupt as normal GSI interrupt Currently Xen Domain0 has special treatment for ACPI SCI interrupt, that is initialize irq for ACPI SCI at early stage in a special way as: xen_init_IRQ() ->pci_xen_initial_domain() ->xen_setup_acpi_sci() Allocate and initialize irq for ACPI SCI Function xen_setup_acpi_sci() calls acpi_gsi_to_irq() to get an irq number for ACPI SCI. But unfortunately acpi_gsi_to_irq() depends on IOAPIC irqdomains through following path acpi_gsi_to_irq() ->mp_map_gsi_to_irq() ->mp_map_pin_to_irq() ->check IOAPIC irqdomain For PV domains, it uses Xen event based interrupt manangement and doesn't make uses of native IOAPIC, so no irqdomains created for IOAPIC. This causes Xen domain0 fail to install interrupt handler for ACPI SCI and all ACPI events will be lost. Please refer to: https://lkml.org/lkml/2014/12/19/178 So the fix is to get rid of special treatment for ACPI SCI, just treat ACPI SCI as normal GSI interrupt as: acpi_gsi_to_irq() ->acpi_register_gsi() ->acpi_register_gsi_xen() ->xen_register_gsi() With above change, there's no need for xen_setup_acpi_sci() anymore. The above change also works with bare metal kernel too.
