      ocfs2/dlm: fix possible convert=sion deadlock · 6718cb5e
      Xue jiufei authored
      We found there is a conversion deadlock when the owner of lockres
      happened to crash before send DLM_PROXY_AST_MSG for a downconverting
      lock.  The situation is as follows:
      
      Node1                            Node2                  Node3
                                 the owner of lockresA
      lock_1 granted at EX mode
      and call ocfs2_cluster_unlock
      to decrease ex_holders.
                                                       converting lock_3 from
                                                       NL to EX
                                 send DLM_PROXY_AST_MSG
                                 to Node1, asking Node 1
                                 to downconvert.
      receiving DLM_PROXY_AST_MSG,
      thread ocfs2dc send
      DLM_CONVERT_LOCK_MSG
      to Node2 to downconvert
      lock_1(EX->NL).
                                 lock_1 can be granted and
                                 put it into pending_asts
                                 list, return DLM_NORMAL.
                                 then something happened
                                 and Node2 crashed.
      received DLM_NORMAL, waiting
      for DLM_PROXY_AST_MSG.
                                                     selected as the recovery
                                                     master, receving migrate
                                                     lock from Node1, queue
                                                     lock_1 to the tail of
                                                     converting list.
      
      After dlm recovery, converting list in the master of lockresA(Node3)
      will be: converting list head <-> lock_3(NL->EX) <->lock_1(EX<->NL).
      Requested mode of lock_3 is not compatible with the granted mode of
      lock_1, so it can not be granted.  and lock_1 can not downconvert
      because covnerting queue is strictly FIFO.  So a deadlock is created.
      We think function dlm_process_recovery_data() should queue_ast for
      lock_1 or alter the order of lock_1 and lock_3, so dlm_thread can
      process lock_1 first.  And if there are multiple downconverting locks,
      they must convert form PR to NL, so no need to sort them.

      ocfs2: limit printk when journal is aborted · 55b465b6
      Joseph Qi authored
      Once JBD2_ABORT is set, ocfs2_commit_cache will fail in
      ocfs2_commit_thread.  Then it will get into a loop with mass logs.  This
      will meaninglessly consume a larger number of resource and may lead to
      the system hanging.  So limit printk in this case.

      George Spelvin authored
      There are two standard techniques for dereferencing structures pointed
      to by void *: cast to the right type each time they're used, or assign
      to local variables of the right type.

      sh: Replace __get_cpu_var uses · c473b2c6
      Christoph Lameter authored
      __get_cpu_var() is used for multiple purposes in the kernel source.  One
      of them is address calculation via the form &__get_cpu_var(x).  This
      calculates the address for the instance of the percpu variable of the
      current processor based on an offset.
      
      Other use cases are for storing and retrieving data from the current
      processors percpu area.  __get_cpu_var() can be used as an lvalue when
      writing data or on the right side of an assignment.
      
      __get_cpu_var() is defined as :
      
      #define __get_cpu_var(var) (*this_cpu_ptr(&(var)))
      
      __get_cpu_var() always only does an address determination.  However, store
      and retrieve operations could use a segment prefix (or global register on
      other platforms) to avoid the address calculation.
      
      this_cpu_write() and this_cpu_read() can directly take an offset into a
      percpu area and use optimized assembly code to read and write per cpu
      variables.
      
      This patch converts __get_cpu_var into either an explicit address
      calculation using this_cpu_ptr() or into a use of this_cpu operations that
      use the offset.  Thereby address calculations are avoided and less
      registers are used when code is generated.
      
      At the end of the patch set all uses of __get_cpu_var have been removed so
      the macro is removed too.
      
      The patch set includes passes over all arches as well.  Once these
      operations are used throughout then specialized macros can be defined in
      non -x86 arches as well in order to optimize per cpu access by f.e.  using
      a global register that may be set to the per cpu base.
      
      Transformations done to __get_cpu_var()
      
      1. Determine the address of the percpu instance of the current processor.
      
      	DEFINE_PER_CPU(int, y);
      	int *x = &__get_cpu_var(y);
      
          Converts to
      
      	int *x = this_cpu_ptr(&y);
      
      2. Same as #1 but this time an array structure is involved.
      
      	DEFINE_PER_CPU(int, y[20]);
      	int *x = __get_cpu_var(y);
      
          Converts to
      
      	int *x = this_cpu_ptr(y);
      
      3. Retrieve the content of the current processors instance of a per cpu
      variable.
      
      	DEFINE_PER_CPU(int, y);
      	int x = __get_cpu_var(y)
      
         Converts to
      
      	int x = __this_cpu_read(y);
      
      4. Retrieve the content of a percpu struct
      
      	DEFINE_PER_CPU(struct mystruct, y);
      	struct mystruct x = __get_cpu_var(y);
      
         Converts to
      
      	memcpy(&x, this_cpu_ptr(&y), sizeof(x));
      
      5. Assignment to a per cpu variable
      
      	DEFINE_PER_CPU(int, y)
      	__get_cpu_var(y) = x;
      
         Converts to
      
      	__this_cpu_write(y, x);
      
      6. Increment/Decrement etc of a per cpu variable
      
      	DEFINE_PER_CPU(int, y);
      	__get_cpu_var(y)++
      
         Converts to
      
      	__this_cpu_inc(y)

      fanotify: check file flags passed in fanotify_init · 48149e9d
      Heinrich Schuchardt authored
      Without this patch fanotify_init does not validate the value passed in
      event_f_flags.
      
      When a fanotify event is read from the fanotify file descriptor a new
      file descriptor is created where file.f_flags = event_f_flags.
      
      Internal and external open flags are stored together in field f_flags of
      struct file.  Hence, an application might create file descriptors with
      internal flags like FMODE_EXEC, FMODE_NOCMTIME set.
      
      Jan Kara and Eric Paris both aggreed that this is a bug and the value of
      event_f_flags should be checked:
        https://lkml.org/lkml/2014/4/29/522
        https://lkml.org/lkml/2014/4/29/539
      
      This updated patch version considers the comments by Michael Kerrisk in
        https://lkml.org/lkml/2014/5/4/10
      
      With the patch the value of event_f_flags is checked.
      When specifying an invalid value error EINVAL is returned.
      
      Internal flags are disallowed.
      
      File creation flags are disallowed:
      O_CREAT, O_DIRECTORY, O_EXCL, O_NOCTTY, O_NOFOLLOW, O_TRUNC, and O_TTY_INIT.
      
      Flags which do not make sense with fanotify are disallowed:
      __O_TMPFILE, O_PATH, FASYNC, and O_DIRECT.
      
      This leaves us with the following allowed values:
      
      O_RDONLY, O_WRONLY, O_RDWR are basic functionality. The are stored in the
      bits given by O_ACCMODE.
      
      O_APPEND is working as expected. The value might be useful in a logging
      application which appends the current status each time the log is opened.
      
      O_LARGEFILE is needed for files exceeding 4GB on 32bit systems.
      
      O_NONBLOCK may be useful when monitoring slow devices like tapes.
      
      O_NDELAY is equal to O_NONBLOCK except for platform parisc.
      To avoid code breaking on parisc either both flags should be
      allowed or none. The patch allows both.
      
      __O_SYNC and O_DSYNC may be used to avoid data loss on power disruption.
      
      O_NOATIME may be useful to reduce disk activity.
      
      O_CLOEXEC may be useful, if separate processes shall be used to scan files.
      
      Once this patch is accepted, the fanotify_init.2 manpage has to be updated.

      Before the patch, read creates FAN_ACCESS_PERM and FAN_ACCESS events,
      readdir creates only FAN_ACCESS_PERM events.
      
      This is inconsistent.
      
      After the patch, readdir creates FAN_ACCESS_PERM and FAN_ACCESS events.

      fanotify: FAN_MARK_FLUSH: avoid having to provide a fake/invalid fd and path · 0a8dd2db
      Heinrich Schuchardt authored
      Originally from Tvrtko Ursulin (https://lkml.org/lkml/2011/1/12/112)
      
      Avoid having to provide a fake/invalid fd and path when flushing marks
      
      Currently for a group to flush marks it has set it needs to provide a
      fake or invalid (but resolvable) file descriptor and path when calling
      fanotify_mark.  This patch pulls the flush handling a bit up so file
      descriptor and path are completely ignored when flushing.
      
      I reworked the patch to be applicable again (the signature of
      fanotify_mark has changed since Tvrtko's work).

      Commit 786235ee ("kthread: make kthread_create() killable") meant
      for allowing kthread_create() to abort as soon as killed by the

      hugetlb: restrict hugepage_migration_support() to x86_64 · c177c81e
      Naoya Horiguchi authored
      Currently hugepage migration is available for all archs which support
      pmd-level hugepage, but testing is done only for x86_64 and there're
      bugs for other archs.  So to avoid breaking such archs, this patch
      limits the availability strictly to x86_64 until developers of other
      archs get interested in enabling this feature.
      
      Simply disabling hugepage migration on non-x86_64 archs is not enough to
      fix the reported problem where sys_move_pages() hits the BUG_ON() in
      follow_page(FOLL_GET), so let's fix this by checking if hugepage
      migration is supported in vma_migratable().

      Pull ACPI and power management updates from Rafael Wysocki:
       "ACPICA is the leader this time (63 commits), followed by cpufreq (28
        commits), devfreq (15 commits), system suspend/hibernation (12
        commits), ACPI video and ACPI device enumeration (10 commits each).
      
        We have no major new features this time, but there are a few
        significant changes of how things work.  The most visible one will
        probably be that we are now going to create platform devices rather
        than PNP devices by default for ACPI device objects with _HID.  That
        was long overdue and will be really necessary to be able to use the
        same drivers for the same hardware blocks on ACPI and DT-based systems
        going forward.  We're not expecting fallout from this one (as usual),
        but it's something to watch nevertheless.
      
        The second change having a chance to be visible is that ACPI video
        will now default to using native backlight rather than the ACPI
        backlight interface which should generally help systems with broken
        Win8 BIOSes.  We're hoping that all problems with the native backlight
        handling that we had previously have been addressed and we are in a
        good enough shape to flip the default, but this change should be easy
        enough to revert if need be.
      
        In addition to that, the system suspend core has a new mechanism to
        allow runtime-suspended devices to stay suspended throughout system
        suspend/resume transitions if some extra conditions are met
        (generally, they are related to coordination within device hierarchy).
        However, enabling this feature requires cooperation from the bus type
        layer and for now it has only been implemented for the ACPI PM domain
        (used by ACPI-enumerated platform devices mostly today).
      
        Also, the acpidump utility that was previously shipped as a separate
        tool will now be provided by the upstream ACPICA along with the rest
        of ACPICA code, which will allow it to be more up to date and better
        supported, and we have one new cpuidle driver (ARM clps711x).
      
        The rest is improvements related to certain specific use cases,
        cleanups and fixes all over the place.
      
        Specifics:
      
         - ACPICA update to upstream version 20140424.  That includes a number
           of fixes and improvements related to things like GPE handling,
           table loading, headers, memory mapping and unmapping, DSDT/SSDT
           overriding, and the Unload() operator.  The acpidump utility from
           upstream ACPICA is included too.  From Bob Moore, Lv Zheng, David
           Box, David Binderman, and Colin Ian King.
      
         - Fixes and cleanups related to ACPI video and backlight interfaces
           from Hans de Goede.  That includes blacklist entries for some new
           machines and using native backlight by default.
      
         - ACPI device enumeration changes to create platform devices rather
           than PNP devices for ACPI device objects with _HID by default.  PNP
           devices will still be created for the ACPI device object with
           device IDs corresponding to real PNP devices, so that change should
           not break things left and right, and we're expecting to see more
           and more ACPI-enumerated platform devices in the future.  From
           Zhang Rui and Rafael J Wysocki.
      
         - Updates for the ACPI LPSS (Low-Power Subsystem) driver allowing it
           to handle system suspend/resume on Asus T100 correctly.  From
           Heikki Krogerus and Rafael J Wysocki.
      
         - PM core update introducing a mechanism to allow runtime-suspended
           devices to stay suspended over system suspend/resume transitions if
           certain additional conditions related to coordination within device
           hierarchy are met.  Related PM documentation update and ACPI PM
           domain support for the new feature.  From Rafael J Wysocki.
      
         - Fixes and improvements related to the "freeze" sleep state.  They
           affect several places including cpuidle, PM core, ACPI core, and
           the ACPI battery driver.  From Rafael J Wysocki and Zhang Rui.
      
         - Miscellaneous fixes and updates of the ACPI core from Aaron Lu,
           Bjørn Mork, Hanjun Guo, Lan Tianyu, and Rafael J Wysocki.
      
         - Fixes and cleanups for the ACPI processor and ACPI PAD (Processor
           Aggregator Device) drivers from Baoquan He, Manuel Schölling, Tony
           Camuso, and Toshi Kani.
      
         - System suspend/resume optimization in the ACPI battery driver from
           Lan Tianyu.
      
         - OPP (Operating Performance Points) subsystem updates from Chander
           Kashyap, Mark Brown, and Nishanth Menon.
      
         - cpufreq core fixes, updates and cleanups from Srivatsa S Bhat,
           Stratos Karafotis, and Viresh Kumar.
      
         - Updates, fixes and cleanups for the Tegra, powernow-k8, imx6q,
           s5pv210, nforce2, and powernv cpufreq drivers from Brian Norris,
           Jingoo Han, Paul Bolle, Philipp Zabel, Stratos Karafotis, and
           Viresh Kumar.
      
         - intel_pstate driver fixes and cleanups from Dirk Brandewie, Doug
           Smythies, and Stratos Karafotis.
      
         - Enabling the big.LITTLE cpufreq driver on arm64 from Mark Brown.
      
         - Fix for the cpuidle menu governor from Chander Kashyap.
      
         - New ARM clps711x cpuidle driver from Alexander Shiyan.
      
         - Hibernate core fixes and cleanups from Chen Gang, Dan Carpenter,
           Fabian Frederick, Pali Rohár, and Sebastian Capella.
      
         - Intel RAPL (Running Average Power Limit) driver updates from Jacob
           Pan.
      
         - PNP subsystem updates from Bjorn Helgaas and Fabian Frederick.
      
         - devfreq core updates from Chanwoo Choi and Paul Bolle.
      
         - devfreq updates for exynos4 and exynos5 from Chanwoo Choi and
           Bartlomiej Zolnierkiewicz.
      
         - turbostat tool fix from Jean Delvare.
      
         - cpupower tool updates from Prarit Bhargava, Ramkumar Ramachandra
           and Thomas Renninger.

      Pull KVM updates from Paolo Bonzini:
       "At over 200 commits, covering almost all supported architectures, this
        was a pretty active cycle for KVM.  Changes include:
      
         - a lot of s390 changes: optimizations, support for migration, GDB
           support and more
      
         - ARM changes are pretty small: support for the PSCI 0.2 hypercall
           interface on both the guest and the host (the latter acked by
           Catalin)
      
         - initial POWER8 and little-endian host support
      
         - support for running u-boot on embedded POWER targets
      
         - pretty large changes to MIPS too, completing the userspace
           interface and improving the handling of virtualized timer hardware
      
         - for x86, a larger set of changes is scheduled for 3.17.  Still, we
           have a few emulator bugfixes and support for running nested
           fully-virtualized Xen guests (para-virtualized Xen guests have
           always worked).  And some optimizations too.
      
        The only missing architecture here is ia64.  It's not a coincidence
        that support for KVM on ia64 is scheduled for removal in 3.17"

       "This must be about the smallest merge window patch set ever for GFS2.
        It is probably also the first one without a single patch from me.
        That is down to a combination of factors, and I have some things in
        the works that are not quite ready yet, that I hope to put in next
        time around.
      
        Returning to what is here this time...  we have 3 patches which fix
        various warnings.  Two are bug fixes (for quotas and also a rare
        recovery race condition).  The final patch, from Ben Marzinski, is an
        important change in the freeze code which has been in progress for
        some time.  This removes the need to take and drop the transaction
        lock for every single transaction, when the only time it was used, was
        at file system freeze time.  Ben's patch integrates the freeze
        operation into the journal flush code as an alternative with lower
        overheads and also lands up resolving some difficult to fix races at
        the same time"
