      s390/mm: limit STACK_RND_MASK for compat tasks · e143fa93
      Martin Schwidefsky authored
      For compat tasks the mmap randomization does not use the maximum
      randomization value from mmap_rnd_mask but the fixed value of 0x7ff.
      This needs to be respected in the definition of STACK_RND_MASK as

      s390/cpum_sf: add diagnostic sampling event only if it is authorized · 0a648150
      Hendrik Brueckner authored
      The SF_CYCLES_BASIC_DIAG is always registered even if it is turned of in the
      current hardware configuration.  Because diagnostic-sampling is typically not
      turned on in the hardware configuration, do not register this perf event by
      default.  Enable it only if the diagnostic-sampling function is authorized.

      memcg: disable hierarchy support if bound to the legacy cgroup hierarchy · 7feee590
      Vladimir Davydov authored
      If the memory cgroup controller is initially mounted in the scope of the
      default cgroup hierarchy and then remounted to a legacy hierarchy, it will
      still have hierarchy support enabled, which is incorrect.  We should
      disable hierarchy support if bound to the legacy cgroup hierarchy.

      mm: reorder can_do_mlock to fix audit denial · a5a6579d
      Jeff Vander Stoep authored
      A userspace call to mmap(MAP_LOCKED) may result in the successful locking
      of memory while also producing a confusing audit log denial.  can_do_mlock
      checks capable and rlimit.  If either of these return positive
      can_do_mlock returns true.  The capable check leads to an LSM hook used by
      apparmour and selinux which produce the audit denial.  Reordering so
      rlimit is checked first eliminates the denial on success, only recording a
      denial when the lock is unsuccessful as a result of the denial.

      kasan, module, vmalloc: rework shadow allocation for modules · a5af5aa8
      Andrey Ryabinin authored
      Current approach in handling shadow memory for modules is broken.
      Shadow memory could be freed only after memory shadow corresponds it is no
      longer used.  vfree() called from interrupt context could use memory its
      freeing to store 'struct llist_node' in it:
          void vfree(const void *addr)
              if (unlikely(in_interrupt())) {
                  struct vfree_deferred *p = this_cpu_ptr(&vfree_deferred);
                  if (llist_add((struct llist_node *)addr, &p->list))
      Later this list node used in free_work() which actually frees memory.
      Currently module_memfree() called in interrupt context will free shadow
      before freeing module's memory which could provoke kernel crash.
      So shadow memory should be freed after module's memory.  However, such
      deallocation order could race with kasan_module_alloc() in module_alloc().
      Free shadow right before releasing vm area.  At this point vfree()'d
      memory is not used anymore and yet not available for other allocations.
      New VM_KASAN flag used to indicate that vm area has dynamically allocated
      shadow memory so kasan frees shadow only if it was previously allocated.

      fanotify: fix event filtering with FAN_ONDIR set · b3c1030d
      Suzuki K. Poulose authored
      With FAN_ONDIR set, the user can end up getting events, which it hasn't
      marked.  This was revealed with fanotify04 testcase failure on
      Linux-4.0-rc1, and is a regression from 3.19, revealed with 66ba93c0
      ("fanotify: don't set FAN_ONDIR implicitly on a marks ignored mask").
         # /opt/ltp/testcases/bin/fanotify04
         [ ... ]
        fanotify04    7  TPASS  :  event generated properly for type 100000
        fanotify04    8  TFAIL  :  fanotify04.c:147: got unexpected event 30
        fanotify04    9  TPASS  :  No event as expected
      The testcase sets the adds the following marks : FAN_OPEN | FAN_ONDIR for
      a fanotify on a dir.  Then does an open(), followed by close() of the
      directory and expects to see an event FAN_OPEN(0x20).  However, the
      fanotify returns (FAN_OPEN|FAN_CLOSE_NOWRITE(0x10)).  This happens due to
      the flaw in the check for event_mask in fanotify_should_send_event() which
      	if (event_mask & marks_mask & ~marks_ignored_mask)
      		return true;
      where, event_mask == (FAN_ONDIR | FAN_CLOSE_NOWRITE),
             marks_mask == (FAN_ONDIR | FAN_OPEN),
             marks_ignored_mask == 0
      Fix this by masking the outgoing events to the user, as we already take
      care of FAN_ONDIR and FAN_EVENT_ON_CHILD.

      nilfs2: fix deadlock of segment constructor during recovery · 283ee148
      Ryusuke Konishi authored
      According to a report from Yuxuan Shui, nilfs2 in kernel 3.19 got stuck
      during recovery at mount time.  The code path that caused the deadlock was
      as follows:
              * Do roll-forwarding, attach segment constructor for recovery,
                and kick it.
                 * A lock is held with nilfs_transaction_lock()
                                       nilfs_transaction_lock() --> deadlock
      This can happen if commit 7ef3ff2f ("nilfs2: fix deadlock of segment
      constructor over I_SYNC flag") is applied and roll-forward recovery was
      performed at mount time.  The roll-forward recovery can happen if datasync
      write is done and the file system crashes immediately after that.  For
      instance, we can reproduce the issue with the following steps:
       < nilfs2 is mounted on /nilfs (device: /dev/sdb1) >
       # dd if=/dev/zero of=/nilfs/test bs=4k count=1 && sync
       # dd if=/dev/zero of=/nilfs/test conv=notrunc oflag=dsync bs=4k
       count=1 && reboot -nfh
       < the system will immediately reboot >
       # mount -t nilfs2 /dev/sdb1 /nilfs
      The deadlock occurs because iput() can run segment constructor through
      writeback_single_inode() if MS_ACTIVE flag is not set on sb->s_flags.  The
      above commit changed segment constructor so that it calls iput()
      asynchronously for inodes with i_nlink == 0, but that change was
      This fixes the another deadlock by deferring iput() in segment constructor
      even for the case that mount is not finished, that is, for the case that
      MS_ACTIVE flag is not set.

      mm: cma: fix CMA aligned offset calculation · 850fc430
      Danesh Petigara authored
      The CMA aligned offset calculation is incorrect for non-zero order_per_bit
      For example, if cma->order_per_bit=1, cma->base_pfn= 0x2f800000 and
      align_order=12, the function returns a value of 0x17c00 instead of 0x400.
      This patch fixes the CMA aligned offset calculation.
      The previous calculation was wrong and would return too-large values for
      the offset, so that when cma_alloc looks for free pages in the bitmap with
      the requested alignment > order_per_bit, it starts too far into the bitmap
      and so CMA allocations will fail despite there actually being plenty of
      free pages remaining.  It will also probably have the wrong alignment.
      With this change, we will get the correct offset into the bitmap.
      One affected user is powerpc KVM, which has kvm_cma->order_per_bit set to
      KVM_CMA_CHUNK_ORDER - PAGE_SHIFT, or 18 - 12 = 6.

      mm, oom: do not fail __GFP_NOFAIL allocation if oom killer is disabled · e009d5dc
      Michal Hocko authored
      Tetsuo Handa has pointed out that __GFP_NOFAIL allocations might fail
      after OOM killer is disabled if the allocation is performed by a kernel
      thread.  This behavior was introduced from the very beginning by
      7f33d49a ("mm, PM/Freezer: Disable OOM killer when tasks are frozen").
       This means that the basic contract for the allocation request is broken
      and the context requesting such an allocation might blow up unexpectedly.
      There are basically two ways forward.
      1) move oom_killer_disable after kernel threads are frozen.  This has a
         risk that the OOM victim wouldn't be able to finish because it would
         depend on an already frozen kernel thread.  This would be really tricky
         to debug.
      2) do not fail GFP_NOFAIL allocation no matter what and risk a
         potential Freezable kernel threads will loop and fail the suspend.
         Incidental allocations after kernel threads are frozen will at least
         dump a warning - if we are lucky and the serial console is still active
         of course...
      This patch implements the later option because it is safer.  We would see
      warning rather than allocation failures for the kernel threads which would
      blow up otherwise and have a higher chances to identify __GFP_NOFAIL users
      from deeper pm code.

      drivers/rtc/rtc-s3c.c: add .needs_src_clk to s3c6410 RTC data · 8792f777
      Javier Martinez Canillas authored
      Commit df9e26d0 ("rtc: s3c: add support for RTC of Exynos3250 SoC")
      added an "rtc_src" DT property to specify the clock used as a source to
      the S3C real-time clock.
      Not all SoCs needs this so commit eaf3a659 ("drivers/rtc/rtc-s3c.c:
      fix initialization failure without rtc source clock") changed to check
      the struct s3c_rtc_data .needs_src_clk to conditionally grab the clock.
      But that commit didn't update the data for each IP version so the RTC
      broke on the boards that needs a source clock. This is the case of at
      least Exynos5250 and Exynos5440 which uses the s3c6410 RTC IP block.
      This commit fixes the S3C rtc on the Exynos5250 Snow and Exynos5420
      Peach Pit and Pi Chromebooks.

      ocfs2: make append_dio an incompat feature · 18d585f0
      Mark Fasheh authored
      It turns out that making this feature ro_compat isn't quite enough to
      prevent accidental corruption on mount from older kernels.  Ocfs2 (like
      other file systems) will process orphaned inodes even when the user mounts
      in 'ro' mode.  So for the case of a filesystem not knowing the append_dio
      feature, mounting the filesystem could result in orphaned-for-dio files
      being deleted, which we clearly don't want.
      So instead, turn this into an incompat flag.
      Btw, this is kind of my fault - initially I asked that we add a flag to
      cover the feature and even suggested that we use an ro flag.  It wasn't
      until I was looking through our commits for v4.0-rc1 that I realized we
      actually want this to be incompat.

      Pull seq-buf/ftrace fixes from Steven Rostedt:
       "This includes fixes for seq_buf_bprintf() truncation issue.  It also
        contains fixes to ftrace when /proc/sys/kernel/ftrace_enabled and
        function tracing are started.  Doing the following causes some issues:
          # echo 0 > /proc/sys/kernel/ftrace_enabled
          # echo function_graph > /sys/kernel/debug/tracing/current_tracer
          # echo 1 > /proc/sys/kernel/ftrace_enabled
          # echo nop > /sys/kernel/debug/tracing/current_tracer
          # echo function_graph > /sys/kernel/debug/tracing/current_tracer
        As well as with function tracing too.  Pratyush Anand first reported
        this issue to me and supplied a patch.  When I tested this on my x86
        test box, it caused thousands of backtraces and warnings to appear in
        dmesg, which also caused a denial of service (a warning for every
        function that was listed).  I applied Pratyush's patch but it did not
        fix the issue for me.  I looked into it and found a slight problem
        with trampoline accounting.  I fixed it and sent Pratyush a patch, but
        he said that it did not fix the issue for him.
        I later learned tha Pratyush was using an ARM64 server, and when I
        tested on my ARM board, I was able to reproduce the same issue as
        Pratyush.  After applying his patch, it fixed the problem.  The above
        test uncovered two different bugs, one in x86 and one in ARM and
        ARM64.  As this looked like it would affect PowerPC, I tested it on my
        PPC64 box.  It too broke, but neither the patch that fixed ARM or x86
        fixed this box (the changes were all in generic code!).  The above
        test, uncovered two more bugs that affected PowerPC.  Again, the
        changes were only done to generic code.  It's the way the arch code
        expected things to be done that was different between the archs.  Some
        where more sensitive than others.
        The rest of this series fixes the PPC bugs as well"

      Pull networking fixes from David Miller:
       1) nft_compat accidently truncates ethernet protocol to 8-bits, from
          Arturo Borrero.
       2) Memory leak in ip_vs_proc_conn(), from Julian Anastasov.
       3) Don't allow the space required for nftables rules to exceed the
          maximum value representable in the dlen field.  From Patrick
       4) bcm63xx_enet can accidently leave interrupts permanently disabled
          due to errors in the NAPI polling exit logic.  Fix from Nicolas
       5) Fix OOPSes triggerable by the ping protocol module, due to missing
          address family validations etc.  From Lorenzo Colitti.
       6) Don't use RCU locking in sleepable context in team driver, from Jiri
       7) xen-netback miscalculates statistic offset pointers when reporting
          the stats to userspace.  From David Vrabel.
       8) Fix a leak of up to 256 pages per VIF destroy in xen-netaback, also
          from David Vrabel.
       9) ip_check_defrag() cannot assume that skb_network_offset(),
          particularly when it is used by the AF_PACKET fanout defrag code.
          From Alexander Drozdov.
      10) gianfar driver doesn't query OF node names properly when trying to
          determine the number of hw queues available.  Fix it to explicitly
          check for OF nodes named queue-group.  From Tobias Waldekranz.
      11) MID field in macb driver should be 12 bits, not 16.  From Punnaiah
          Choudary Kalluri.
      12) Fix unintentional regression in traceroute due to timestamp socket
          option changes.  Empty ICMP payloads should be allowed in
          non-timestamp cases.  From Willem de Bruijn.
      13) When devices are unregistered, we have to get rid of AF_PACKET
          multicast list entries that point to it via ifindex.  Fix from
          Francesco Ruggeri.
