Jan Kara and Thomas Gleixner reported boot crashes in the FPU code: general protection fault: 0000 [#1] SMP RIP: 0010:[<ffffffff81048a6c>] [<ffffffff81048a6c>] mxcsr_feature_mask_init+0x1c/0x40 2b:* 0f ae 85 00 fe ff ff fxsave -0x200(%rbp) and bisected it down to the following FPU commit: 91a8c2a5 ("x86/fpu: Clean up and fix MXCSR handling") The reason is that the on-stack FPU registers state variable, used by the FXSAVE instruction, did not have the required minimum alignment of 16 bytes, causing the general protection fault. This is most likely a GCC bug in older GCC versions, but the offending commit also added a bogus extra 32-byte alignment (which GCC ignored too). So fix this bug by making the variable static again, but also mark it __initdata this time, because fpu__init_system_mxcsr() is now an __init function.

Commit 44dba3d5 ("sched: Refactor task_struct to use numa_faults instead of numa_* pointers") modified the way tsk->numa_faults stats are accounted. However that commit never touched show_numa_stats() that is displayed in /proc/pid/sched and thus the numbers displayed in /proc/pid/sched don't match the actual numbers. Fix it by making sure that /proc/pid/sched reflects the task fault numbers. Also add group fault stats too. Also couple of more modifications are added here: 1. Format changes: - Previously we would list two entries per node, one for private and one for shared. Also the home node info was listed in each entry. - Now preferred node, total_faults and current node are displayed separately. - Now there is one entry per node, that lists private,shared task and group faults. 2. Unit changes: - p->numa_pages_migrated was getting reset after every read of /proc/pid/sched. It's more useful to have absolute numbers since differential migrations between two accesses can be more easily calculated.

The motivation for this is support for legacy BE guests on the new LE hosts. There are two redeeming properties that made me merge this: - It's a trivial amount of code: since we wrap host/guest accesses anyway, almost all of it is well hidden from drivers. - Sane platforms would never set flags like VHOST_CROSS_ENDIAN_LEGACY, and when it's clear, there's zero overhead (as some point it was tested by compiling with and without the patches, got the same stripped binary).

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace由 Linus Torvalds 提交于
Pull user namespace updates from Eric Biederman: "Long ago and far away when user namespaces where young it was realized that allowing fresh mounts of proc and sysfs with only user namespace permissions could violate the basic rule that only root gets to decide if proc or sysfs should be mounted at all. Some hacks were put in place to reduce the worst of the damage could be done, and the common sense rule was adopted that fresh mounts of proc and sysfs should allow no more than bind mounts of proc and sysfs. Unfortunately that rule has not been fully enforced. There are two kinds of gaps in that enforcement. Only filesystems mounted on empty directories of proc and sysfs should be ignored but the test for empty directories was insufficient. So in my tree directories on proc, sysctl and sysfs that will always be empty are created specially. Every other technique is imperfect as an ordinary directory can have entries added even after a readdir returns and shows that the directory is empty. Special creation of directories for mount points makes the code in the kernel a smidge clearer about it's purpose. I asked container developers from the various container projects to help test this and no holes were found in the set of mount points on proc and sysfs that are created specially. This set of changes also starts enforcing the mount flags of fresh mounts of proc and sysfs are consistent with the existing mount of proc and sysfs. I expected this to be the boring part of the work but unfortunately unprivileged userspace winds up mounting fresh copies of proc and sysfs with noexec and nosuid clear when root set those flags on the previous mount of proc and sysfs. So for now only the atime, read-only and nodev attributes which userspace happens to keep consistent are enforced. Dealing with the noexec and nosuid attributes remains for another time. This set of changes also addresses an issue with how open file descriptors from /proc/<pid>/ns/* are displayed. Recently readlink of /proc/<pid>/fd has been triggering a WARN_ON that has not been meaningful since it was added (as all of the code in the kernel was converted) and is not now actively wrong. There is also a short list of issues that have not been fixed yet that I will mention briefly. It is possible to rename a directory from below to above a bind mount. At which point any directory pointers below the renamed directory can be walked up to the root directory of the filesystem. With user namespaces enabled a bind mount of the bind mount can be created allowing the user to pick a directory whose children they can rename to outside of the bind mount. This is challenging to fix and doubly so because all obvious solutions must touch code that is in the performance part of pathname resolution. As mentioned above there is also a question of how to ensure that developers by accident or with purpose do not introduce exectuable files on sysfs and proc and in doing so introduce security regressions in the current userspace that will not be immediately obvious and as such are likely to require breaking userspace in painful ways once they are recognized" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: vfs: Remove incorrect debugging WARN in prepend_path mnt: Update fs_fully_visible to test for permanently empty directories sysfs: Create mountpoints with sysfs_create_mount_point sysfs: Add support for permanently empty directories to serve as mount points. kernfs: Add support for always empty directories. proc: Allow creating permanently empty directories that serve as mount points sysctl: Allow creating permanently empty directories that serve as mountpoints. fs: Add helper functions for permanently empty directories. vfs: Ignore unlocked mounts in fs_fully_visible mnt: Modify fs_fully_visible to deal with locked ro nodev and atime mnt: Refactor the logic for mounting sysfs and proc in a user namespace

Eric noticed problems with vhost-scsi and virtio-ccw: vhost-scsi complained about overwriting values in the config space, which was triggered by a broken implementation of virtio-ccw's config get/set routines. It was probably sheer luck that we did not hit this before. When writing a value to the config space, the WRITE_CONF ccw will always write from the beginning of the config space up to and including the value to be set. If the config space up to the value has not yet been retrieved from the device, however, we'll end up overwriting values. Keep track of the known config space and update if needed to avoid this. Moreover, READ_CONF will only read the number of bytes it has been instructed to retrieve, so we must not copy more than that to the buffer, or we might overwrite trailing values.

Memory-mapped LVT0 register already contains the new value when APICv traps so we can't directly detect a change. Memorize a bit we are interested in to enable legacy NMI watchdog.

Writes were a bit racy, but hard to turn into a bug at the same time. (Particularly because modern Linux doesn't use this feature anymore.)

Commit 1cde2930 ("sched/preempt: Add static_key() to preempt_notifiers") had two problems. First, the preempt-notifier API needs to sleep with the addition of the static_key, we do however need to hold off preemption while modifying the preempt notifier list, otherwise a preemption could observe an inconsistent list state. KVM correctly registers and unregisters preempt notifiers with preemption disabled, so the sleep caused dmesg splats. Second, KVM registers and unregisters preemption notifiers very often (in vcpu_load/vcpu_put). With a single uniprocessor guest the static key would move between 0 and 1 continuously, hitting the slow path on every userspace exit. To fix this, wrap the static_key inc/dec in a new API, and call it from KVM.

Commit 86dca36e introduced ratelimited usage for 'unhandled_signal' messages. The commit checks the ratelimit irrespective of whether the signal is handled or not, which is wrong and leads to false reports like the below in dmesg : __do_user_fault: 127 callbacks suppressed Do the ratelimit check only if the signal is unhandled.

It is normal that firmware presents GICC entry or entries (processors) with disabled flag in ACPI MADT, taking a system of 16 cpus for example, ACPI firmware may present 8 ebabled first with another 8 cpus disabled in MADT, the disabled cpus can be hot-added later. Firmware may also present more cpus than the hardware actually has, but disabled the unused ones, and easily enable it when the hardware has such cpus to make the firmware code scalable. So that's not an error for disabled cpus in MADT, we can switch pr_err() to pr_debug() to make the boot a little quieter by default. Since hwid for disabled cpus often are invalid, and we check invalid hwid first in the code, for use case that hot add cpus later will be filtered out and will not be counted in possible cups, so move this check before the hwid one to prepare the code to count for disabeld cpus when cpu hot-plug is introduced.

Pull ACPICA updates from Rafael Wysocki: "Additional ACPICA material for v4.2-rc1 This will update the ACPICA code in the kernel to upstream revision 20150619 (a bug-fix release mostly including stable-candidate fixes) and restore an earlier ACPICA commit that had to be reverted due to a regression introduced by it (the regression is addressed by blacklisting the only known system affected by it to date). The only new feature added by this update is the support for overriding objects in the ACPI namespace and a new ACPI table that can be used for that called the Override System Definition Table (OSDT). That should allow us to "patch" the ACPI namespace built from incomplete or incorrect ACPI System Definition tables (DSDT, SSDT) during system startup without the need to provide replacements for all of those tables in the future. Specifics: - Fix system resume problems related to 32-bit and 64-bit versions of the Firmware ACPI Control Structure (FACS) in the firmare (Lv Zheng) - Fix double initialization of the FACS (Lv Zheng) - Add _CLS object processing code to ACPICA (Suravee Suthikulpanit) - Add support for the (currently missing) new GIC version field in the Multiple APIC Description Table (MADT) (Hanjun Guo) - Add support for overriding objects in the ACPI namespace to ACPICA and OSDT support (Lv Zheng, Bob Moore, Zhang Rui) - Updates related to the TCPA and TPM2 ACPI tables (Bob Moore) - Restore the commit modifying _REV to always return "2" (as required by ACPI 6) and add a blacklisting mechanism for systems that may be affected by that change (Rafael J Wysocki) - Assorted fixes and cleanups (Bob Moore, Lv Zheng, Sascha Wildner)" * tag 'acpica-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (28 commits) Revert 'Revert "ACPICA: Permanently set _REV to the value '2'."'
