      mm: bootmem: fix free_all_bootmem_core() with odd bitmap alignment · 10d73e65
      Max Filippov 提交于
      Currently free_all_bootmem_core ignores that node_min_pfn may be not
      multiple of BITS_PER_LONG.  Eg commit 6dccdcbe ("mm: bootmem: fix
      checking the bitmap when finally freeing bootmem") shifts vec by lower
      bits of start instead of lower bits of idx.  Also
      
        if (IS_ALIGNED(start, BITS_PER_LONG) && vec == ~0UL)
      
      assumes that vec bit 0 corresponds to start pfn, which is only true when
      node_min_pfn is a multiple of BITS_PER_LONG.  Also loop in the else
      clause can double-free pages (e.g.  with node_min_pfn == start == 1,
      map[0] == ~0 on 32-bit machine page 32 will be double-freed).
      
      This bug causes the following message during xtensa kernel boot:
      
        bootmem::free_all_bootmem_core nid=0 start=1 end=8000
        BUG: Bad page state in process swapper  pfn:00001

      The fix is the following:
       - always align vec so that its bit 0 corresponds to start
       - provide BITS_PER_LONG bits in vec, if those bits are available in the
         map
       - don't free pages past next start position in the else clause.

      mm: use aligned zone start for pfn_to_bitidx calculation · c060f943
      Laura Abbott 提交于
      The current calculation in pfn_to_bitidx assumes that (pfn -
      zone->zone_start_pfn) >> pageblock_order will return the same bit for
      all pfn in a pageblock.  If zone_start_pfn is not aligned to
      pageblock_nr_pages, this may not always be correct.
      
      Consider the following with pageblock order = 10, zone start 2MB:
      
        pfn     | pfn - zone start | (pfn - zone start) >> page block order
        ----------------------------------------------------------------
        0x26000 | 0x25e00	   |  0x97
        0x26100 | 0x25f00	   |  0x97
        0x26200 | 0x26000	   |  0x98
        0x26300 | 0x26100	   |  0x98
      
      This means that calling {get,set}_pageblock_migratetype on a single page
      will not set the migratetype for the full block.  Fix this by rounding
      down zone_start_pfn when doing the bitidx calculation.
      
      For our use case, the effects of this bug were mostly tied to the fact
      that CMA allocations would either take a long time or fail to happen.
      Depending on the driver using CMA, this could result in anything from
      visual glitches to application failures.

      fs/exec.c: work around icc miscompilation · 6d92d4f6
      Xi Wang 提交于
      The tricky problem is this check:
      
      	if (i++ >= max)
      
      icc (mis)optimizes this check as:
      
      	if (++i > max)
      
      The check now becomes a no-op since max is MAX_ARG_STRINGS (0x7FFFFFFF).
      
      This is "allowed" by the C standard, assuming i++ never overflows,
      because signed integer overflow is undefined behavior.  This
      optimization effectively reverts the previous commit 362e6663
      ("exec.c, compat.c: fix count(), compat_count() bounds checking") that
      tries to fix the check.
      
      This patch simply moves ++ after the check.

      mm: compaction: fix echo 1 > compact_memory return error issue · 7964c06d
      Jason Liu 提交于
      when run the folloing command under shell, it will return error
      
        sh/$ echo 1 > /proc/sys/vm/compact_memory
        sh/$ sh: write error: Bad address
      
      After strace, I found the following log:
      
        ...
        write(1, "1\n", 2)               = 3
        write(1, "", 4294967295)         = -1 EFAULT (Bad address)
        write(2, "echo: write error: Bad address\n", 31echo: write error: Bad address
        ) = 31
      
      This tells system return 3(COMPACT_COMPLETE) after write data to
      compact_memory.
      
      The fix is to make the system just return 0 instead 3(COMPACT_COMPLETE)
      from sysctl_compaction_handler after compaction_nodes finished.

      mm: memblock: fix wrong memmove size in memblock_merge_regions() · c0232ae8
      Lin Feng 提交于
      The memmove span covers from (next+1) to the end of the array, and the
      index of next is (i+1), so the index of (next+1) is (i+2).  So the size
      of remaining array elements is (type->cnt - (i + 2)).
      
      Since the remaining elements of the memblock array are move forward by
      one element and there is only one additional element caused by this bug.
      So there won't be any write overflow here but read overflow.  It may
      read one more element out of the array address if the array happens to
      be full.  Commonly it doesn't matter at all but if the array happens to
      be located at the end a memblock, it may cause a invalid read operation
      for the physical address doesn't exist.
      
      There are 2 *happens to be* here, so I think the probability is quite
      low, I don't know if any guy is haunted by this bug before.
      
      Mostly I think it's user-invisible.

      drivers/video/ssd1307fb.c: fix bit order bug in the byte translation function · 552f0cc7
      Maxime Ripard 提交于
      This was leading to a strange behaviour when using the fbcon driver on
      top of this one: the letters were in the right order, but each letter
      had a vertical symmetry.
      
      This was because the addressing was right for the byte, but the
      addressing of each individual bit was inverted.

      mm: migrate: check page_count of THP before migrating · 04fa5d6a
      Mel Gorman 提交于
      Hugh Dickins pointed out that migrate_misplaced_transhuge_page() does
      not check page_count before migrating like base page migration and
      khugepage.  He could not see why this was safe and he is right.
      
      The potential impact of the bug is avoided due to the limitations of
      NUMA balancing.  The page_mapcount() check ensures that only a single
      address space is using this page and as THPs are typically private it
      should not be possible for another address space to fault it in
      parallel.  If the address space has one associated task then it's
      difficult to have both a GUP pin and be referencing the page at the same
      time.  If there are multiple tasks then a buggy scenario requires that
      another thread be accessing the page while the direct IO is in flight.
      This is dodgy behaviour as there is a possibility of corruption with or
      without THP migration.  It would be
      
      While we happen to be safe for the most part it is shoddy to depend on
      such "safety" so this patch checks the page count similar to anonymous
      pages.  Note that this does not mean that the page_mapcount() check can
      go away.  If we were to remove the page_mapcount() check the the THP
      would have to be unmapped from all referencing PTEs, replaced with
      migration PTEs and restored properly afterwards.

      lib: cpu_rmap: avoid flushing all workqueues · 896f97ea
      David Decotigny 提交于
      In some cases, free_irq_cpu_rmap() is called while holding a lock (eg
      rtnl).  This can lead to deadlocks, because it invokes
      flush_scheduled_work() which ends up waiting for whole system workqueue
      to flush, but some pending works might try to acquire the lock we are
      already holding.
      
      This commit uses reference-counting to replace
      irq_run_affinity_notifiers().  It also removes
      irq_run_affinity_notifiers() altogether.

      It includes one critical fix - wrong flexcan2 clock will hang system
      when the port gets brought up.  The other two are non-critical fixes,

      s390/3215: partially revert tty close handling fix · 6673cd0b
      Heiko Carstens 提交于
      Partially revert ae289dc1 "s390/3215: fix tty close handling", since this
      leads sometimes to hanging agetty processes and therefore systems that get
      stuck while starting.
      
      This was magically fixed (bisected) by a common code patch from Alan Cox:
      36b3c070 "tty: Move the handling of the tty release logic", however it was
      unrelated.
      
      Since the removed code worked for a decade, nobody knows anymore why it was
      in there in the first place and debugging the observed hang is non-trivial
      (at least for me :) ), let's just re-add the removed code before we see
      other side effects.

      s390/irq: remove split irq fields from /proc/stat · 420f42ec
      Heiko Carstens 提交于
      Now that irq sum accounting for /proc/stat's "intr" line works again we
      have the oddity that the sum field (first field) contains only the sum
      of the second (external irqs) and third field (I/O interrupts).
      The reason for that is that these two fields are already sums of all other
      fields. So if we would sum up everything we would count every interrupt
      twice.
      This is broken since the split interrupt accounting was merged two years
      ago: 052ff461 "[S390] irq: have detailed
      statistics for interrupt types".
      To fix this remove the split interrupt fields from /proc/stat's "intr"
      line again and only have them in /proc/interrupts.
      
      This restores the old behaviour, seems to be the only sane fix and mimics
      a behaviour from other architectures where /proc/interrupts also contains
      more than /proc/stat's "intr" line does.
