      David Hildenbrand authored 
      There was insufficient review and no agreement that this is the right
approach.

There are serious flaws with the implementation that make processes using
mlock() not even work with simple fork() [1] and we get reliable crashes
when rebooting.

Further, simply because we might be unmapping a single PTE of a large
mlocked folio, we shouldn't zero out the whole folio.

... especially because the code can also *corrupt* urelated memory because
	kernel_init_pages(page, folio_nr_pages(folio));

Could end up writing outside of the actual folio if we work with a tail
page.

Let's revert it.  Once there is agreement that this is the right approach,
the issues were fixed and there was reasonable review and proper testing,
we can consider it again.

      mm/page_table_check: fix crash on ZONE_DEVICE · 8bb592c2
      Peter Xu authored 
      Not all pages may apply to pgtable check.  One example is ZONE_DEVICE
pages: they map PFNs directly, and they don't allocate page_ext at all
even if there's struct page around.  One may reference
devm_memremap_pages().

When both ZONE_DEVICE and page-table-check enabled, then try to map some
dax memories, one can trigger kernel bug constantly now when the kernel
was trying to inject some pfn maps on the dax device:

 kernel BUG at mm/page_table_check.c:55!

While it's pretty legal to use set_pxx_at() for ZONE_DEVICE pages for page
fault resolutions, skip all the checks if page_ext doesn't even exist in
pgtable checker, which applies to ZONE_DEVICE but maybe more.

      gcc: disable '-Warray-bounds' for gcc-9 · 8e5bd4ea
      Yury Norov authored 
      '-Warray-bounds' is already disabled for gcc-10+.  Now that we've merged
bitmap_{read,write), I see the following error when building the kernel
with gcc-9.4 (Ubuntu 20.04.4 LTS) for x86_64 allmodconfig:

drivers/pinctrl/pinctrl-cy8c95x0.c: In function `cy8c95x0_read_regs_mask.isra.0':
include/linux/bitmap.h:756:18: error: array subscript [1, 288230376151711744] is outside array bounds of `long unsigned int[1]' [-Werror=array-bounds]
  756 |  value_high = map[index + 1] & BITMAP_LAST_WORD_MASK(start + nbits);
      |               ~~~^~~~~~~~~~~

The immediate reason is that the commit b4475970 ("bitmap: make
bitmap_{get,set}_value8() use bitmap_{read,write}()") switched the
bitmap_get_value8() to an alias of bitmap_read(); the same for 'set'.

Now; the code that triggers Warray-bounds, calls the function like this:

  #define MAX_BANK 8
  #define BANK_SZ 8
  #define MAX_LINE        (MAX_BANK * BANK_SZ)
  DECLARE_BITMAP(tval, MAX_LINE); // 64-bit map: unsigned long tval[1]

  read_val |= bitmap_get_value8(tval, i * BANK_SZ) & ~bits;

bitmap_read() is implemented such that it may conditionally dereference a
pointer beyond the boundary like this:

	unsigned long offset = start % BITS_PER_LONG;
        unsigned long space = BITS_PER_LONG - offset;

        if (space >= nbits)
                return (map[index] >> offset) & BITMAP_LAST_WORD_MASK(nbits);

        value_low = map[index] & BITMAP_FIRST_WORD_MASK(start);
        value_high = map[index + 1] & BITMAP_LAST_WORD_MASK(start + nbits);
        return (value_low >> offset) | (value_high << space);

In case of bitmap_get_value8(), it's impossible to violate the boundary
because 'space >= nbits' is never the true for byte-aligned 8-bit access. 
So, this is clearly a false-positive.

The same type of false-positives break my allmodconfig build in many
places.  gcc-8, is clear, however.

      ocfs2: fix NULL pointer dereference in ocfs2_abort_trigger() · 685d03c3
      Joseph Qi authored 
      bdev->bd_super has been removed and commit 8887b94d change the usage
from bdev->bd_super to b_assoc_map->host->i_sb.  Since ocfs2 hasn't set
bh->b_assoc_map, it will trigger NULL pointer dereference when calling
into ocfs2_abort_trigger().

Actually this was pointed out in history, see commit 74e364ad.  But
I've made a mistake when reviewing commit 8887b94d and then
re-introduce this regression.

Since we cannot revive bdev in buffer head, so fix this issue by
initializing all types of ocfs2 triggers when fill super, and then get the
specific ocfs2 trigger from ocfs2_caching_info when access journal.

      Joseph Qi authored 
      bdev->bd_super has been removed and commit 8887b94d change the usage
from bdev->bd_super to b_assoc_map->host->i_sb.  This introduces the
following NULL pointer dereference in ocfs2_journal_dirty() since
b_assoc_map is still not initialized.  This can be easily reproduced by
running xfstests generic/186, which simulate no more credits.

Fix it by only aborting transaction and journal in ocfs2_journal_dirty()
