      XZ: Fix incorrect XZ_BUF_ERROR · 9c1f8594
      Lasse Collin authored 
      xz_dec_run() could incorrectly return XZ_BUF_ERROR if all of the
following was true:

 - The caller knows how many bytes of output to expect and only provides
   that much output space.

 - When the last output bytes are decoded, the caller-provided input
   buffer ends right before the LZMA2 end of payload marker.  So LZMA2
   won't provide more output anymore, but it won't know it yet and thus
   won't return XZ_STREAM_END yet.

 - A BCJ filter is in use and it hasn't left any unfiltered bytes in the
   temp buffer.  This can happen with any BCJ filter, but in practice
   it's more likely with filters other than the x86 BCJ.

This fixes <https://bugzilla.redhat.com/show_bug.cgi?id=735408> where
Squashfs thinks that a valid file system is corrupt.

This also fixes a similar bug in single-call mode where the uncompressed
size of a block using BCJ + LZMA2 was 0 bytes and caller provided no
output space.  Many empty .xz files don't contain any blocks and thus
don't trigger thi...

      init: carefully handle loglevel option on kernel cmdline. · 808bf29b
      Alexander Sverdlin authored 
      

When a malformed loglevel value (for example "${abc}") is passed on the
kernel cmdline, the loglevel itself is being set to 0.

That then suppresses all following messages, including all the errors
and crashes caused by other malformed cmdline options.  This could make
debugging process quite tricky.

This patch leaves the previous value of loglevel if the new value is
incorrect and reports an error code in this case.

      teach /proc/$pid/numa_maps about transparent hugepages · 32ef4384
      Dave Hansen authored 
      

This is modeled after the smaps code.

It detects transparent hugepages and then does a single gather_stats()
for the page as a whole.  This has two benifits:
 1. It is more efficient since it does many pages in a single shot.
 2. It does not have to break down the huge page.

      break out numa_maps gather_pte_stats() checks · 3200a8aa
      Dave Hansen authored 
      

gather_pte_stats() does a number of checks on a target page
to see whether it should even be considered for statistics.
This breaks that code out in to a separate function so that
we can use it in the transparent hugepage case in the next
patch.

      make /proc/$pid/numa_maps gather_stats() take variable page size · eb4866d0
      Dave Hansen authored 
      

We need to teach the numa_maps code about transparent huge pages.  The
first step is to teach gather_stats() that the pte it is dealing with
might represent more than one page.

Note that will we use this in a moment for transparent huge pages since
they have use a single pmd_t which _acts_ as a "surrogate" for a bunch
of smaller pte_t's.

I'm a _bit_ unhappy that this interface counts in hugetlbfs page sizes
for hugetlbfs pages and PAGE_SIZE for normal pages.  That means that to
figure out how many _bytes_ "dirty=1" means, you must first know the
hugetlbfs page size.  That's easier said than done especially if you
don't have visibility in to the mount.

But, that's probably a discussion for another day especially since it
would change behavior to fix it.  But, just in case anyone wonders why
this patch only passes a '1' in the hugetlb case...

      xfrm: Perform a replay check after return from async codepaths · bcf66bf5
      Steffen Klassert authored 
      

When asyncronous crypto algorithms are used, there might be many
packets that passed the xfrm replay check, but the replay advance
function is not called yet for these packets. So the replay check
function would accept a replay of all of these packets. Also the
system might crash if there are more packets in async processing
than the size of the anti replay window, because the replay advance
function would try to update the replay window beyond the bounds.

This pach adds a second replay check after resuming from the async
processing to fix these issues.

add new fib rule can cause BUG_ON happen
the reproduce shell is
ip rule add pref 38
ip rule add pref 38
ip rule add to 192.168.3.0/24 goto 38
ip rule del pref 38
ip rule add to 192.168.3.0/24 goto 38
ip rule add pref 38

then the BUG_ON will happen
del BUG_ON and use (ctarget == NULL) identify whether this rule is unresolved
