       "Syzbot found a use-after-free bug in seccomp due to flags that should
        not be allowed to be used together.
      
        Tycho fixed this, I updated the self-tests, and the syzkaller PoC has
        been running for several days without triggering KASan (before this
        fix, it would reproduce). These patches have also been in -next for
        almost a week, just to be sure.
      
         - Add logic for making some seccomp flags exclusive (Tycho)
      
         - Update selftests for exclusivity testing (Kees)"

      x86: make ZERO_PAGE() at least parse its argument · 80871482
      Linus Torvalds authored
      This doesn't really do anything, but at least we now parse teh
      ZERO_PAGE() address argument so that we'll catch the most obvious errors
      in usage next time they'll happen.
      
      See commit 6a5c5d26 ("rdma: fix build errors on s390 and MIPS due to
      bad ZERO_PAGE use") what happens when we don't have any use of the macro
      argument at all.

      rdma: fix build errors on s390 and MIPS due to bad ZERO_PAGE use · 6a5c5d26
      Linus Torvalds authored
      The parameter to ZERO_PAGE() was wrong, but since all architectures
      except for MIPS and s390 ignore it, it wasn't noticed until 0-day
      reported the build error.

      selinux: use kernel linux/socket.h for genheaders and mdp · dfbd199a
      Paulo Alcantara authored
      When compiling genheaders and mdp from a newer host kernel, the

      Pull powerpc fixes from Michael Ellerman:
       "A one-liner to make our Radix MMU support depend on HUGETLB_PAGE. We
        use some of the hugetlb inlines (eg. pud_huge()) when operating on the
        linear mapping and if they're compiled into empty wrappers we can
        corrupt memory.
      
        Then two fixes to our VFIO IOMMU code. The first is not a regression
        but fixes the locking to avoid a user-triggerable deadlock.
      
        The second does fix a regression since rc1, and depends on the first
        fix. It makes it possible to run guests with large amounts of memory
        again (~256GB).
      
        Thanks to Alexey Kardashevskiy"
