      net/appletalk: Fix kernel memory disclosure · ce7e40c4
      Vlad Tsyrklevich authored
      ipddp_route structs contain alignment padding so kernel heap memory
      is leaked when they are copied to user space in
      ipddp_ioctl(SIOCFINDIPDDPRT). Change kmalloc() to kzalloc() to clear
      that memory.

      phy state machine: failsafe leave invalid RUNNING state · 811a9191
      Zefir Kurtisi authored
      While in RUNNING state, phy_state_machine() checks for link changes by
      comparing phydev->link before and after calling phy_read_status().
      This works as long as it is guaranteed that phydev->link is never
      changed outside the phy_state_machine().
      
      If in some setups this happens, it causes the state machine to miss
      a link loss and remain RUNNING despite phydev->link being 0.
      
      This has been observed running a dsa setup with a process continuously
      polling the link states over ethtool each second (SNMPD RFC-1213
      agent). Disconnecting the link on a phy followed by a ETHTOOL_GSET
      causes dsa_slave_get_settings() / dsa_slave_get_link_ksettings() to
      call phy_read_status() and with that modify the link status - and
      with that bricking the phy state machine.
      
      This patch adds a fail-safe check while in RUNNING, which causes to
      move to CHANGELINK when the link is gone and we are still RUNNING.

      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:

           __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.

      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.

      net: phy: dp83867: fix irq generation · 5ca7d1ca
      Grygorii Strashko authored
      For proper IRQ generation by DP83867 phy the INT/PWDN pin has to be
      programmed as an interrupt output instead of a Powerdown input in
      Configuration Register 3 (CFG3), Address 0x001E, bit 7 INT_OE = 1. The
      current driver doesn't do this and as result IRQs will not be generated by
      DP83867 phy even if they are properly configured in DT.
      
      Hence, fix IRQ generation by properly configuring CFG3.INT_OE bit and
      ensure that Link Status Change (LINK_STATUS_CHNG_INT) and Auto-Negotiation
      Complete (AUTONEG_COMP_INT) interrupt are enabled. After this the DP83867
      driver will work properly in interrupt enabled mode.

      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.
