      AppArmor: Use GFP_KERNEL for __aa_kvmalloc(). · a7f6c1b6
      Tetsuo Handa authored
      Calling kmalloc(GFP_NOIO) with order == PAGE_ALLOC_COSTLY_ORDER is not
      recommended because it might fall into infinite retry loop without
      invoking the OOM killer.
      
      Since aa_dfa_unpack() is the only caller of kvzalloc() and
      aa_dfa_unpack() which is calling kvzalloc() via unpack_table() is
      doing kzalloc(GFP_KERNEL), it is safe to use GFP_KERNEL from
      __aa_kvmalloc().
      
      Since aa_simple_write_to_buffer() is the only caller of kvmalloc()
      and aa_simple_write_to_buffer() is calling copy_from_user() which
      is GFP_KERNEL context (see memdup_user_nul()), it is safe to use
      GFP_KERNEL from __aa_kvmalloc().
      
      Therefore, replace GFP_NOIO with GFP_KERNEL. Also, since we have
      vmalloc() fallback, add __GFP_NORETRY so that we don't invoke the OOM
      killer by kmalloc(GFP_KERNEL) with order == PAGE_ALLOC_COSTLY_ORDER.

      mm: workingset: fix use-after-free in shadow node shrinker · ea07b862
      Johannes Weiner authored
      Several people report seeing warnings about inconsistent radix tree
      nodes followed by crashes in the workingset code, which all looked like
      use-after-free access from the shadow node shrinker.
      
      Dave Jones managed to reproduce the issue with a debug patch applied,
      which confirmed that the radix tree shrinking indeed frees shadow nodes
      while they are still linked to the shadow LRU:
      
        WARNING: CPU: 2 PID: 53 at lib/radix-tree.c:643 delete_node+0x1e4/0x200
        CPU: 2 PID: 53 Comm: kswapd0 Not tainted 4.10.0-rc2-think+ #3
        Call Trace:
           delete_node+0x1e4/0x200
           __radix_tree_delete_node+0xd/0x10
           shadow_lru_isolate+0xe6/0x220
           __list_lru_walk_one.isra.4+0x9b/0x190
           list_lru_walk_one+0x23/0x30
           scan_shadow_nodes+0x2e/0x40
           shrink_slab.part.44+0x23d/0x5d0
           shrink_node+0x22c/0x330
           kswapd+0x392/0x8f0
      
      This is the WARN_ON_ONCE(!list_empty(&node->private_list)) placed in the
      inlined radix_tree_shrink().
      
      The problem is with 14b46879 ("mm: workingset: move shadow entry
      tracking to radix tree exceptional tracking"), which passes an update
      callback into the radix tree to link and unlink shadow leaf nodes when
      tree entries change, but forgot to pass the callback when reclaiming a
      shadow node.
      
      While the reclaimed shadow node itself is unlinked by the shrinker, its
      deletion from the tree can cause the left-most leaf node in the tree to
      be shrunk.  If that happens to be a shadow node as well, we don't unlink
      it from the LRU as we should.
      
      Consider this tree, where the s are shadow entries:
      
             root->rnode
                  |
             [0       n]
              |       |
           [s    ] [sssss]
      
      Now the shadow node shrinker reclaims the rightmost leaf node through
      the shadow node LRU:
      
             root->rnode
                  |
             [0        ]
              |
          [s     ]
      
      Because the parent of the deleted node is the first level below the
      root and has only one child in the left-most slot, the intermediate
      level is shrunk and the node containing the single shadow is put in
      its place:
      
             root->rnode
                  |
             [s        ]
      
      The shrinker again sees a single left-most slot in a first level node
      and thus decides to store the shadow in root->rnode directly and free
      the node - which is a leaf node on the shadow node LRU.
      
        root->rnode
             |
             s
      
      Without the update callback, the freed node remains on the shadow LRU,
      where it causes later shrinker runs to crash.
      
      Pass the node updater callback into __radix_tree_delete_node() in case
      the deletion causes the left-most branch in the tree to collapse too.
      
      Also add warnings when linked nodes are freed right away, rather than
      wait for the use-after-free when the list is scanned much later.
      
      Fixes: 14b46879 ("mm: workingset: move shadow entry tracking to radix tree exceptional tracking")

      mm: stop leaking PageTables · b0b9b3df
      Hugh Dickins authored
      4.10-rc loadtest (even on x86, and even without THPCache) fails with
      "fork: Cannot allocate memory" or some such; and /proc/meminfo shows
      PageTables growing.
      
      Commit 953c66c2 ("mm: THP page cache support for ppc64") that got
      merged in rc1 removed the freeing of an unused preallocated pagetable
      after do_fault_around() has called map_pages().
      
      This is usually a good optimization, so that the followup doesn't have
      to reallocate one; but it's not sufficient to shift the freeing into
      alloc_set_pte(), since there are failure cases (most commonly
      VM_FAULT_RETRY) which never reach finish_fault().
      
      Check and free it at the outer level in do_fault(), then we don't need
      to worry in alloc_set_pte(), and can restore that to how it was (I
      cannot find any reason to pte_free() under lock as it was doing).
      
      And fix a separate pagetable leak, or crash, introduced by the same
      change, that could only show up on some ppc64: why does do_set_pmd()'s
      failure case attempt to withdraw a pagetable when it never deposited
      one, at the same time overwriting (so leaking) the vmf->prealloc_pte?
      Residue of an earlier implementation, perhaps? Delete it.

      Pull ACPI fixes from Rafael Wysocki:
       "These fix a device enumeration problem related to _ADR matching and an
        IOMMU initialization issue related to the DMAR table missing, remove
        an excessive function call from the core ACPI code, update an error
        message in the ACPI WDAT watchdog driver and add a way to work around
        problems with unhandled GPE notifications.
      
        Specifics:
      
         - Fix a device enumeration issue leading to incorrect associations
           between ACPI device objects and platform device objects
           representing physical devices if the given device object has both
           _ADR and _HID (Rafael Wysocki).
      
         - Avoid passing NULL to acpi_put_table() during IOMMU initialization
           which triggers a (rightful) warning from ACPICA (Rafael Wysocki).
      
         - Drop an excessive call to acpi_dma_deconfigure() from the core code
           that binds ACPI device objects to device objects representing
           physical devices (Lorenzo Pieralisi).
      
         - Update an error message in the ACPI WDAT watchdog driver to make it
           provide more useful information (Mika Westerberg).
      
         - Add a mechanism to work around issues with unhandled GPE
           notifications that occur during system initialization and cannot be
           prevented by means of sysfs (Lv Zheng)"

      Pull power management fixes from Rafael Wysocki:
       "These fix a few issues in the intel_pstate driver, a documetation
        issue, a false-positive compiler warning in the generic power domains
        framework and two problems in the devfreq subsystem. They also update

           attribute values in sysfs in sync (Rafael Wysocki).
      
         - Drop confusing kernel-doc references related to power management
           and ACPI from the driver API manual (Rafael Wysocki).
      
         - Make a false-positive compiler warning in the generic power domains
           framework go away (Augusto Mecking Caringi).
      
         - Fix two initialization issues in the devfreq subsystem and update
           the MAINTAINERS entry for it (Chanwoo Choi).

      swiotlb: Export swiotlb_max_segment to users · 7453c549
      Konrad Rzeszutek Wilk authored
      So they can figure out what is the optimal number of pages
      that can be contingously stitched together without fear of
      bounce buffer.
      
      We also expose an mechanism for sub-users of SWIOTLB API, such
      as Xen-SWIOTLB to set the max segment value. And lastly
      if swiotlb=force is set (which mandates we bounce buffer everything)
      we set max_segment so at least we can bounce buffer one 4K page
      instead of a giant 512KB one for which we may not have space.
