      x86/mm/64: Initialize CR4.PCIDE early · c7ad5ad2
      Andy Lutomirski 提交于
      cpu_init() is weird: it's called rather late (after early
      identification and after most MMU state is initialized) on the boot
      CPU but is called extremely early (before identification) on secondary
      CPUs.  It's called just late enough on the boot CPU that its CR4 value
      isn't propagated to mmu_cr4_features.
      
      Even if we put CR4.PCIDE into mmu_cr4_features, we'd hit two
      problems.  First, we'd crash in the trampoline code.  That's
      fixable, and I tried that.  It turns out that mmu_cr4_features is
      totally ignored by secondary_start_64(), though, so even with the
      trampoline code fixed, it wouldn't help.
      
      This means that we don't currently have CR4.PCIDE reliably initialized
      before we start playing with cpu_tlbstate.  This is very fragile and
      tends to cause boot failures if I make even small changes to the TLB
      handling code.
      
      Make it more robust: initialize CR4.PCIDE earlier on the boot CPU
      and propagate it to secondary CPUs in start_secondary().
      
      ( Yes, this is ugly.  I think we should have improved mmu_cr4_features
        to actually control CR4 during secondary bootup, but that would be
        fairly intrusive at this stage. )

      x86/hibernate/64: Mask off CR3's PCID bits in the saved CR3 · f34902c5
      Andy Lutomirski 提交于
      Jiri reported a resume-from-hibernation failure triggered by PCID.
      The root cause appears to be rather odd.  The hibernation asm
      restores a CR3 value that comes from the image header.  If the image
      kernel has PCID on, it's entirely reasonable for this CR3 value to
      have one of the low 12 bits set.  The restore code restores it with
      CR4.PCIDE=0, which means that those low 12 bits are accepted by the
      CPU but are either ignored or interpreted as a caching mode.  This
      is odd, but still works.  We blow up later when the image kernel
      restores CR4, though, since changing CR4.PCIDE with CR3[11:0] != 0
      is illegal.  Boom!
      
      FWIW, it's entirely unclear to me what's supposed to happen if a PAE
      kernel restores a non-PAE image or vice versa.  Ditto for LA57.

      xfs: XFS_IS_REALTIME_INODE() should be false if no rt device present · b31ff3cd
      Richard Wareing 提交于
      If using a kernel with CONFIG_XFS_RT=y and we set the RHINHERIT flag on
      a directory in a filesystem that does not have a realtime device and
      create a new file in that directory, it gets marked as a real time file.
      When data is written and a fsync is issued, the filesystem attempts to
      flush a non-existent rt device during the fsync process.
      
      This results in a crash dereferencing a null buftarg pointer in
      xfs_blkdev_issue_flush():
      
        BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
        IP: xfs_blkdev_issue_flush+0xd/0x20
        .....
        Call Trace:
          xfs_file_fsync+0x188/0x1c0

          entry_SYSCALL64_slow_path+0x25/0x25
      
      Setting RT inode flags does not require special privileges so any
      unprivileged user can cause this oops to occur.  To reproduce, confirm
      kernel is compiled with CONFIG_XFS_RT=y and run:
      
        # mkfs.xfs -f /dev/pmem0
        # mount /dev/pmem0 /mnt/test
        # mkdir /mnt/test/foo
        # xfs_io -c 'chattr +t' /mnt/test/foo
        # xfs_io -f -c 'pwrite 0 5m' -c fsync /mnt/test/foo/bar
      
      Or just run xfstests with MKFS_OPTIONS="-d rtinherit=1" and wait.
      
      Kernels built with CONFIG_XFS_RT=n are not exposed to this bug.

      f2fs: clear radix tree dirty tag of pages whose dirty flag is cleared · 0abd8e70
      Daeho Jeong 提交于
      On a senario like writing out the first dirty page of the inode
      as the inline data, we only cleared dirty flags of the pages, but
      didn't clear the dirty tags of those pages in the radix tree.
      
      If we don't clear the dirty tags of the pages in the radix tree, the
      inodes which contain the pages will be marked with I_DIRTY_PAGES again
      and again, and writepages() for the inodes will be invoked in every
      writeback period. As a result, nothing will be done in every
      writepages() for the inodes and it will just consume CPU time
      meaninglessly.

      Pull namespace updates from Eric Biederman:
       "Life has been busy and I have not gotten half as much done this round
        as I would have liked. I delayed it so that a minor conflict
        resolution with the mips tree could spend a little time in linux-next
        before I sent this pull request.
      
        This includes two long delayed user namespace changes from Kirill
        Tkhai. It also includes a very useful change from Serge Hallyn that
        allows the security capability attribute to be used inside of user
        namespaces. The practical effect of this is people can now untar
        tarballs and install rpms in user namespaces. It had been suggested to
        generalize this and encode some of the namespace information
        information in the xattr name. Upon close inspection that makes the
        things that should be hard easy and the things that should be easy
        more expensive.
      
        Then there is my bugfix/cleanup for signal injection that removes the
        magic encoding of the siginfo union member from the kernel internal
        si_code. The mips folks reported the case where I had used FPE_FIXME
        me is impossible so I have remove FPE_FIXME from mips, while at the
        same time including a return statement in that case to keep gcc from
        complaining about unitialized variables.
      
        I almost finished the work to get make copy_siginfo_to_user a trivial
        copy to user. The code is available at:
      
           git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git neuter-copy_siginfo_to_user-v3
      
        But I did not have time/energy to get the code posted and reviewed
        before the merge window opened.
      
        I was able to see that the security excuse for just copying fields
        that we know are initialized doesn't work in practice there are buggy
        initializations that don't initialize the proper fields in siginfo. So
        we still sometimes copy unitialized data to userspace"

      Revert "firmware: add sanity check on shutdown/suspend" · f007cad1
      Linus Torvalds 提交于
      This reverts commit 81f95076.
      
      It causes random failures of firmware loading at resume time (well,
      random for me, it seems to be more reliable for others) because the
      firmware disabling is not actually synchronous with any particular
      resume event, and at least the btusb driver that uses a workqueue to
      load the firmware at resume seems to occasionally hit the "firmware
      loading is disabled" logic because the firmware loader hasn't gotten the
      resume event yet.
      
      Some kind of sanity check for not trying to load firmware when it's not
      possible might be a good thing, but this commit was not it.
      
      Greg seems to have silently suffered the same issue, and pointed to the
      likely culprit, and Gabriel C verified the revert fixed it for him too.

      m68k: Add braces to __pmd(x) initializer to kill compiler warning · 4c2b5e0f
      Geert Uytterhoeven 提交于
      With gcc 4.1.2:
      
          include/linux/swapops.h: In function ‘swp_entry_to_pmd’:
          include/linux/swapops.h:294: warning: missing braces around initializer
          include/linux/swapops.h:294: warning: (near initialization for ‘(anonymous).pmd’)
      
      Due to a GCC zero initializer bug (#53119), the standard "(pmd_t){ 0 }"
      initializer is not accepted by all GCC versions.
      In addition, on m68k pmd_t is an array instead of a single value, so we
      need "(pmd_t){ { 0 }, }" instead of "(pmd_t){ 0 }".
      
      Based on commit 9157259d ("mm: add pmd_t initializer __pmd() to
      work around a GCC bug.") for sparc32.
