      revert "mm: fix-up zone present pages" · 5576646f
      Andrew Morton authored
      Revert commit 7f1290f2
      
       ("mm: fix-up zone present pages")
      
      That patch tried to fix a issue when calculating zone->present_pages,
      but it caused a regression on 32bit systems with HIGHMEM.  With that
      change, reset_zone_present_pages() resets all zone->present_pages to
      zero, and fixup_zone_present_pages() is called to recalculate
      zone->present_pages when the boot allocator frees core memory pages into
      buddy allocator.  Because highmem pages are not freed by bootmem
      allocator, all highmem zones' present_pages becomes zero.
      
      Various options for improving the situation are being discussed but for
      now, let's return to the 3.6 code.

      tmpfs: change final i_blocks BUG to WARNING · 0f3c42f5
      Hugh Dickins authored
      
      
      Under a particular load on one machine, I have hit shmem_evict_inode()'s
      BUG_ON(inode->i_blocks), enough times to narrow it down to a particular
      race between swapout and eviction.
      
      It comes from the "if (freed > 0)" asymmetry in shmem_recalc_inode(),
      and the lack of coherent locking between mapping's nrpages and shmem's
      swapped count.  There's a window in shmem_writepage(), between lowering
      nrpages in shmem_delete_from_page_cache() and then raising swapped
      count, when the freed count appears to be +1 when it should be 0, and
      then the asymmetry stops it from being corrected with -1 before hitting
      the BUG.
      
      One answer is coherent locking: using tree_lock throughout, without
      info->lock; reasonable, but the raw_spin_lock in percpu_counter_add() on
      used_blocks makes that messier than expected.  Another answer may be a
      further effort to eliminate the weird shmem_recalc_inode() altogether,
      but previous attempts at that failed.
      
      So far undecided, but for now change the BUG_ON to WARN_ON: in usual
      circumstances it remains a useful consistency check.

      Thanks to Johannes for pointing to truncation: free_swap_and_cache()
      only does a trylock on the page, so the page lock we've held since
      before confirming swap is not enough to protect against truncation.
      
      What cleanup is needed in this case? Just delete_from_swap_cache(),
      which takes care of the memcg uncharge.

      mm: highmem: don't treat PKMAP_ADDR(LAST_PKMAP) as a highmem address · 498c2280
      Will Deacon authored
      
      
      kmap_to_page returns the corresponding struct page for a virtual address
      of an arbitrary mapping.  This works by checking whether the address
      falls in the pkmap region and using the pkmap page tables instead of the
      linear mapping if appropriate.
      
      Unfortunately, the bounds checking means that PKMAP_ADDR(LAST_PKMAP) is
      incorrectly treated as a highmem address and we can end up walking off
      the end of pkmap_page_table and subsequently passing junk to pte_page.
      
      This patch fixes the bound check to stay within the pkmap tables.

      mm: revert "mm: vmscan: scale number of pages reclaimed by reclaim/compaction based on failures" · 96710098
      Mel Gorman authored
      Jiri Slaby reported the following:
      
      	(It's an effective revert of "mm: vmscan: scale number of pages
      	reclaimed by reclaim/compaction based on failures".) Given kswapd
      	had hours of runtime in ps/top output yesterday in the morning
      	and after the revert it's now 2 minutes in sum for the last 24h,
      	I would say, it's gone.
      
      The intention of the patch in question was to compensate for the loss of
      lumpy reclaim.  Part of the reason lumpy reclaim worked is because it
      aggressively reclaimed pages and this patch was meant to be a sane
      compromise.
      
      When compaction fails, it gets deferred and both compaction and
      reclaim/compaction is deferred avoid excessive reclaim.  However, since
      commit c6543459 ("mm: remove __GFP_NO_KSWAPD"), kswapd is woken up
      each time and continues reclaiming which was not taken into account when
      the patch was developed.
      
      Attempts to address the problem ended up just changing the shape of the
      problem instead of fixing it.  The release window gets closer and while
      a THP allocation failing is not a major problem, kswapd chewing up a lot
      of CPU is.
      
      This patch reverts commit 83fde0f2
      
       ("mm: vmscan: scale number of
      pages reclaimed by reclaim/compaction based on failures") and will be
      revisited in the future.

      memcg: fix hotplugged memory zone oops · bea8c150
      Hugh Dickins authored
      
      
      When MEMCG is configured on (even when it's disabled by boot option),
      when adding or removing a page to/from its lru list, the zone pointer
      used for stats updates is nowadays taken from the struct lruvec.  (On
      many configurations, calculating zone from page is slower.)
      
      But we have no code to update all the lruvecs (per zone, per memcg) when
      a memory node is hotadded.  Here's an extract from the oops which
      results when running numactl to bind a program to a newly onlined node:
      
        BUG: unable to handle kernel NULL pointer dereference at 0000000000000f60
        IP:  __mod_zone_page_state+0x9/0x60
        Pid: 1219, comm: numactl Not tainted 3.6.0-rc5+ #180 Bochs Bochs
        Process numactl (pid: 1219, threadinfo ffff880039abc000, task ffff8800383c4ce0)
        Call Trace:
          __pagevec_lru_add_fn+0xdf/0x140
          pagevec_lru_move_fn+0xb1/0x100
          __pagevec_lru_add+0x1c/0x30
          lru_add_drain_cpu+0xa3/0x130
          lru_add_drain+0x2f/0x40
         ...
      
      The natural solution might be to use a memcg callback whenever memory is
      hotadded; but that solution has not been scoped out, and it happens that
      we do have an easy location at which to update lruvec->zone.  The lruvec
      pointer is discovered either by mem_cgroup_zone_lruvec() or by
      mem_cgroup_page_lruvec(), and both of those do know the right zone.
      
      So check and set lruvec->zone in those; and remove the inadequate
      attempt to set lruvec->zone from lruvec_init(), which is called before
      NODE_DATA(node) has been allocated in such cases.
      
      Ah, there was one exceptionr.  For no particularly good reason,
      mem_cgroup_force_empty_list() has its own code for deciding lruvec.
      Change it to use the standard mem_cgroup_zone_lruvec() and
      mem_cgroup_get_lru_size() too.  In fact it was already safe against such
      an oops (the lru lists in danger could only be empty), but we're better
      proofed against future changes this way.
      
      I've marked this for stable (3.6) since we introduced the problem in 3.5
      (now closed to stable); but I have no idea if this is the only fix
      needed to get memory hotadd working with memcg in 3.6, and received no
      answer when I enquired twice before.

      memcg: oom: fix totalpages calculation for memory.swappiness==0 · 9a5a8f19
      Michal Hocko authored
      oom_badness() takes a totalpages argument which says how many pages are
      available and it uses it as a base for the score calculation.  The value
      is calculated by mem_cgroup_get_limit which considers both limit and
      total_swap_pages (resp.  memsw portion of it).
      
      This is usually correct but since fe35004f
      
       ("mm: avoid swapping out
      with swappiness==0") we do not swap when swappiness is 0 which means
      that we cannot really use up all the totalpages pages.  This in turn
      confuses oom score calculation if the memcg limit is much smaller than
      the available swap because the used memory (capped by the limit) is
      negligible comparing to totalpages so the resulting score is too small
      if adj!=0 (typically task with CAP_SYS_ADMIN or non zero oom_score_adj).
      A wrong process might be selected as result.
      
      The problem can be worked around by checking mem_cgroup_swappiness==0
      and not considering swap at all in such a case.

      mm: fix build warning for uninitialized value · 1756954c
      David Rientjes authored
      
      
      do_wp_page() sets mmun_called if mmun_start and mmun_end were
      initialized and, if so, may call mmu_notifier_invalidate_range_end()
      with these values.  This doesn't prevent gcc from emitting a build
      warning though:
      
        mm/memory.c: In function `do_wp_page':
        mm/memory.c:2530: warning: `mmun_start' may be used uninitialized in this function
        mm/memory.c:2531: warning: `mmun_end' may be used uninitialized in this function
      
      It's much easier to initialize the variables to impossible values and do
      a simple comparison to determine if they were initialized to remove the
      bool entirely.

      EPT] introduced the unconditional access to SECONDARY_VM_EXEC_CONTROL,
      and this triggers kernel warnings like below on old CPUs:
      
          vmwrite error: reg 401e value a0568000 (err 12)

      control to avoid these warnings.

       1) tx_filtered/ps_tx_buf queues need to be accessed with the SKB queue
          lock, from Arik Nemtsov.
      
       2) Don't call 802.11 driver's filter configure method until it's
          actually open, from Felix Fietkau.
      
       3) Use ieee80211_free_txskb otherwise we leak control information.
          From Johannes Berg.
      
       4) Fix memory leak in bluetooth UUID removal,f rom Johan Hedberg.
      
       5) The shift mask trick doesn't work properly when 'optname' is out of
          range in do_ip_setsockopt().  Use a straightforward switch statement
          instead, the compiler emits essentially the same code but without
          the missing range check.  From Xi Wang.
      
       6) Fix when we call tcp_replace_ts_recent() otherwise we can
          erroneously accept a too-high tsval.  From Eric Dumazet.
      
       7) VXLAN bug fixes, mostly to do with VLAN header length handling, from
          Alexander Duyck.
      
       8) Missing return value initialization for IPV6_MINHOPCOUNT socket
          option handling.  From Hannes Frederic.
      
       9) Fix regression in tasklet handling in jme/ksz884x/xilinx drivers,
          from Xiaotian Feng.
      
      10) At smsc911x driver init time, we don't know if the chip is in word
          swap mode or not.  However we do need to wait for the control
          register's ready bit to be set before we program any other part of
          the chip.  Adjust the wait loop to account for this.  From Kamlakant
          Patel.
      
      11) Revert erroneous MDIO bus unregister change to mdio-bitbang.c
      
      12) Fix memory leak in /proc/net/sctp/, from Tommi Rantala.
      
      13) tilegx driver registers IRQ with NULL name, oops, from Simon Marchi.
      
      14) TCP metrics hash table kzalloc() based allocation can fail, back
          down to using vmalloc() if it does.  From Eric Dumazet.

      John W. Linville says:
      
      ====================
      This batch of fixes is intended for the 3.7 stream...
      
      This includes a pull of the Bluetooth tree.  Gustavo says:
      
      "A few important fixes to go into 3.7. There is a new hw support by Marcos
      Chaparro. Johan added a memory leak fix and hci device index list fix.
      Also Marcel fixed a race condition in the device set up that was prevent the
      bt monitor to work properly. Last, Paulo Sérgio added a fix to the error
      status when pairing for LE fails. This was prevent userspace to work to handle
      the failure properly."
      
      Regarding the mac80211 pull, Johannes says:
      
      "I have a locking fix for some SKB queues, a variable initialization to
      avoid crashes in a certain failure case, another free_txskb fix from
      Felix and another fix from him to avoid calling a stopped driver, a fix
      for a (very unlikely) memory leak and a fix to not send null data
      packets when resuming while not associated."
      
      Regarding the iwlwifi pull, Johannes says:
      
      "Two more fixes for iwlwifi ... one to use ieee80211_free_txskb(), and
      one to check DMA mapping errors, please pull."
      
      On top of that, Johannes also included a wireless regulatory fix
      to allow 40 MHz on channels 12 and 13 in world roaming mode.  Also,
      Hauke Mehrtens fixes a #ifdef typo in brcmfmac.

      net-rps: Fix brokeness causing OOO packets · baefa31d
      Tom Herbert authored
      In commit c445477d
      
       which adds aRFS to the kernel, the CPU
      selected for RFS is not set correctly when CPU is changing.
      This is causing OOO packets and probably other issues.

      Included fixes are:
      - update the client entry status flags when using the "early client
        detection". This makes the Distributed AP isolation correctly work;
      - transfer the client entry status flags when recovering the translation
        table from another node. This makes the Distributed AP isolation correctly
        work;
      - prevent the "early client detection mechanism" to add clients belonging to
        other backbone nodes in the same LAN. This breaks connectivity when using this
        mechanism together with the Bridge Loop Avoidance
      - process broadcast packets with the Bridge Loop Avoidance before any other
        component. BLA can possibly drop the packets based on the source address. This
        makes the "early client detection mechanism" correctly work when used with
        BLA.
