      rapidio/tsi721: fix tasklet termination in dma channel release · 04379dff
      Alexandre Bounine authored
      This patch is a modification of the patch originally proposed by
      Xiaotian Feng <xtfeng@gmail.com>: https://lkml.org/lkml/2012/11/5/413
      This new version disables DMA channel interrupts and ensures that the
      tasklet wil not be scheduled again before calling tasklet_kill().
      
      Unfortunately the updated patch was not released at that time due to
      planned rework of Tsi721 mport driver to use threaded interrupts (which
      has yet to happen).  Recently the issue was reported again:
      https://lkml.org/lkml/2014/2/19/762.
      
      Description from the original Xiaotian's patch:
      
       "Some drivers use tasklet_disable in device remove/release process,
        tasklet_disable will inc tasklet->count and return.  If the tasklet is
        not handled yet under some softirq pressure, the tasklet will be
        placed on the tasklet_vec, never have a chance to be excuted.  This
        might lead to a heavy loaded ksoftirqd, wakeup with pending_softirq,
        but tasklet is disabled.  tasklet_kill should be used in this case."
      
      This patch is applicable to kernel versions starting from v3.5.

      hfsplus: fix remount issue · bd2c0035
      Vyacheslav Dubeyko authored
      Current implementation of HFS+ driver has small issue with remount
      option.  Namely, for example, you are unable to remount from RO mode
      into RW mode by means of command "mount -o remount,rw /dev/loop0
      /mnt/hfsplus".  Trying to execute sequence of commands results in an
      error message:
      
        mount /dev/loop0 /mnt/hfsplus
        mount -o remount,ro /dev/loop0 /mnt/hfsplus
        mount -o remount,rw /dev/loop0 /mnt/hfsplus
      
        mount: you must specify the filesystem type
      
        mount -t hfsplus -o remount,rw /dev/loop0 /mnt/hfsplus
      
        mount: /mnt/hfsplus not mounted or bad option
      
      The reason of such issue is failure of mount syscall:
      
        mount("/dev/loop0", "/mnt/hfsplus", 0x2282a60, MS_MGC_VAL|MS_REMOUNT, NULL) = -1 EINVAL (Invalid argument)
      
      Namely, hfsplus_parse_options_remount() method receives empty "input"
      argument and return false in such case.  As a result, hfsplus_remount()
      returns -EINVAL error code.
      
      This patch fixes the issue by means of return true for the case of empty
      "input" argument in hfsplus_parse_options_remount() method.

      sh: prefix sh-specific "CCR" and "CCR2" by "SH_" · a5f6ea29
      Geert Uytterhoeven authored
      Commit bcf24e1d ("mmc: omap_hsmmc: use the generic config for
      omap2plus devices"), enabled the build for other platforms for compile
      testing.
      
      sh-allmodconfig now fails with:
      
          include/linux/omap-dma.h:171:8: error: expected identifier before numeric constant
          make[4]: *** [drivers/mmc/host/omap_hsmmc.o] Error 1
      
      This happens because SuperH #defines "CCR", which is one of the enum
      values in include/linux/omap-dma.h.  There's a similar issue with "CCR2"
      on sh2a.
      
      As "CCR" and "CCR2" are too generic names for global #defines, prefix
      them with "SH_" to fix this.

      ocfs2: fix quota file corruption · 15c34a76
      Jan Kara authored
      Global quota files are accessed from different nodes.  Thus we cannot
      cache offset of quota structure in the quota file after we drop our node
      reference count to it because after that moment quota structure may be
      freed and reallocated elsewhere by a different node resulting in
      corruption of quota file.
      
      Fix the problem by clearing dq_off when we are releasing dquot structure.
      We also remove the DB_READ_B handling because it is useless -
      DQ_ACTIVE_B is set iff DQ_READ_B is set.

      kallsyms: fix absolute addresses for kASLR · 0f55159d
      Andy Honig authored
      Currently symbols that are absolute addresses are incorrectly displayed
      in /proc/kallsyms if the kernel is loaded with kASLR.
      
      The problem was that the scripts/kallsyms.c file which generates the
      array of symbol names and addresses uses an relocatable value for all
      symbols, even absolute symbols.  This patch fixes that.
      
      Several kallsyms output in different boot states for comparison:
      
        $ egrep '_(stext|_per_cpu_(start|end))' /root/kallsyms.nokaslr

      scripts/gen_initramfs_list.sh: fix flags for initramfs LZ4 compression · 5ec384d4
      Daniel M. Weeks authored
      LZ4 as implemented in the kernel differs from the default method now
      used by the reference implementation of LZ4.  Until the in-kernel method
      is updated to support the new default, passing the legacy flag (-l) to
      the compressor is necessary.  Without this flag the kernel-generated,
      LZ4-compressed initramfs is junk.
      
      Kyungsik said:

        ---[ end trace a0088dcf07ae10f2 ]---
      
      because munlock_vma_pages_range() thinks it's unexpectedly in the middle
      of a THP page.  This can be reproduced with default config since 3.11
      kernels.  A reproducer can be found in the kernel's selftest directory
      for networking by running ./psock_tpacket.
      
      The problem is that an order=2 compound page (allocated by
      alloc_one_pg_vec_page() is part of the munlocked VM_MIXEDMAP vma (mapped
      by packet_mmap()) and mistaken for a THP page and assumed to be order=9.
      
      The checks for THP in munlock came with commit ff6a6da6 ("mm:
      accelerate munlock() treatment of THP pages"), i.e.  since 3.9, but did
      not trigger a bug.  It just makes munlock_vma_pages_range() skip such
      compound pages until the next 512-pages-aligned page, when it encounters
      a head page.  This is however not a problem for vma's where mlocking has
      no effect anyway, but it can distort the accounting.
      
      Since commit 7225522b ("mm: munlock: batch non-THP page isolation
      and munlock+putback using pagevec") this can trigger a VM_BUG_ON in
      PageTransHuge() check.
      
      This patch fixes the issue by adding VM_MIXEDMAP flag to VM_SPECIAL, a
      list of flags that make vma's non-mlockable and non-mergeable.  The
      reasoning is that VM_MIXEDMAP vma's are similar to VM_PFNMAP, which is
      already on the VM_SPECIAL list, and both are intended for non-LRU pages
      where mlocking makes no sense anyway.  Related Lkml discussion can be
      found in [2].

      memcg: reparent charges of children before processing parent · 4fb1a86f
      Filipe Brandenburger authored
      Sometimes the cleanup after memcg hierarchy testing gets stuck in
      mem_cgroup_reparent_charges(), unable to bring non-kmem usage down to 0.
      
      There may turn out to be several causes, but a major cause is this: the
      workitem to offline parent can get run before workitem to offline child;
      parent's mem_cgroup_reparent_charges() circles around waiting for the
      child's pages to be reparented to its lrus, but it's holding
      cgroup_mutex which prevents the child from reaching its
      mem_cgroup_reparent_charges().
      
      Further testing showed that an ordered workqueue for cgroup_destroy_wq
      is not always good enough: percpu_ref_kill_and_confirm's call_rcu_sched
      stage on the way can mess up the order before reaching the workqueue.
      
      Instead, when offlining a memcg, call mem_cgroup_reparent_charges() on
      all its children (and grandchildren, in the correct order) to have their
      charges reparented first.

      memcg: fix endless loop in __mem_cgroup_iter_next() · ce48225f
      Hugh Dickins authored
      Commit 0eef6156 ("memcg: fix css reference leak and endless loop in
      mem_cgroup_iter") got the interaction with the commit a few before it
      d8ad3055 ("mm/memcg: iteration skip memcgs not yet fully
      initialized") slightly wrong, and we didn't notice at the time.
      
      It's elusive, and harder to get than the original, but for a couple of
      days before rc1, I several times saw a endless loop similar to that
      supposedly being fixed.
      
      This time it was a tighter loop in __mem_cgroup_iter_next(): because we
      can get here when our root has already been offlined, and the ordering
      of conditions was such that we then just cycled around forever.

      dma debug: account for cachelines and read-only mappings in overlap tracking · 3b7a6418
      Dan Williams authored
      While debug_dma_assert_idle() checks if a given *page* is actively
      undergoing dma the valid granularity of a dma mapping is a *cacheline*.
      Sander's testing shows that the warning message "DMA-API: exceeded 7
      overlapping mappings of pfn..." is falsely triggering.  The test is
      simply mapping multiple cachelines in a given page.
      
      Ultimately we want overlap tracking to be valid as it is a real api
      violation, so we need to track active mappings by cachelines.  Update
      the active dma tracking to use the page-frame-relative cacheline of the
      mapping as the key, and update debug_dma_assert_idle() to check for all
      possible mapped cachelines for a given page.
      
      However, the need to track active mappings is only relevant when the
      dma-mapping is writable by the device.  In fact it is fairly standard
      for read-only mappings to have hundreds or thousands of overlapping
      mappings at once.  Limiting the overlap tracking to writable
      (!DMA_TO_DEVICE) eliminates this class of false-positive overlap
      reports.
      
      Note, the radix gang lookup is sub-optimal.  It would be best if it
      stopped fetching entries once the search passed a page boundary.
      Nevertheless, this implementation does not perturb the original net_dma
      failing case.  That is to say the extra overhead does not show up in
      terms of making the failing case pass due to a timing change.

      mm: close PageTail race · 668f9abb
      David Rientjes authored
      Commit bf6bddf1 ("mm: introduce compaction and migration for
      ballooned pages") introduces page_count(page) into memory compaction
      which dereferences page->first_page if PageTail(page).
      
      This results in a very rare NULL pointer dereference on the
      aforementioned page_count(page).  Indeed, anything that does
      compound_head(), including page_count() is susceptible to racing with
      prep_compound_page() and seeing a NULL or dangling page->first_page
      pointer.
      
      This patch uses Andrea's implementation of compound_trans_head() that
      deals with such a race and makes it the default compound_head()
      implementation.  This includes a read memory barrier that ensures that
      if PageTail(head) is true that we return a head page that is neither
      NULL nor dangling.  The patch then adds a store memory barrier to
      prep_compound_page() to ensure page->first_page is set.
      
      This is the safest way to ensure we see the head page that we are
      expecting, PageTail(page) is already in the unlikely() path and the
      memory barriers are unfortunately required.
      
      Hugetlbfs is the exception, we don't enforce a store memory barrier
      during init since no race is possible.
