      Revert fb_ioctl "fix" with extreme prejudice. · a8588521
      Linus Torvalds authored
      As Arjan points out, the patch does exactly the opposite
      of what it was claimed to do.

      [PATCH] loop_set_fd() sendfile check fix · cd546897
      Andrew Morton authored
      From: Yury Umanets <torque@ukrpost.net>
      
      I have found small inconsistency in loop_set_fd().  It checks if
      ->sendfile() is implemented for passed block device file.  But in fact,
      loop back device driver never calls it.  It uses ->sendfile() from backing
      store file.

      [PATCH] i386 hugetlb tlb correction · 57a3170c
      Andrew Morton authored
      From: William Lee Irwin III <wli@holomorphy.com>
      
      i386 does hardware interpretation of pagetables, so pte_clear() can't be
      used on present ptes, as it sets the upper half of the hugepte prior to
      setting the lower half (which includes the valid bit).  i.e.  there is a
      window where having a hugepage mapped at 56GB and doing pte_clear() in
      unmap_hugepage_range() allows other threads of the process to see a
      hugepage at 0 in place of the original hugepage at 56GB.
      
      This patch corrects the situation by using ptep_get_and_clear(), which
      clears the lower word of the pte prior to clearing the upper word.
      
      There is another nasty where huge_page_release() needs to wait for TLB
      flushes before returning the hugepages to the free pool, analogous to the
      issue tlb_remove_page() and tlb_flush_mm() repair.

      Arrange for ioctl(FBIOPUTCMAP) to do copy_to_user() rather than memcpy.

      [PATCH] selinux: remove hardcoded policy assumption from get_user_sids() logic · ed328082
      Andrew Morton authored
      From: Stephen Smalley <sds@epoch.ncsc.mil>
      
      This patch removes a hardcoded policy assumption from the get_user_sids logic
      in the SELinux module that was preventing it from returning contexts that had
      the same type as the caller even if the policy allowed such a transition.  The
      assumption is not valid for all policies, and can be handled via policy
      configuration and userspace rather than hardcoding it in the module logic.

      [PATCH] selinux: add runtime disable · c59f3ad7
      Andrew Morton authored
      From: Stephen Smalley <sds@epoch.ncsc.mil>
      
      This patch adds a kernel configuration option that enables writing to a new
      selinuxfs node 'disable' that allows SELinux to be disabled at runtime prior
      to initial policy load.  SELinux will then remain disabled until next boot.
      This option is similar to the selinux=0 boot parameter, but is to support
      runtime disabling of SELinux, e.g.  from /sbin/init, for portability across
      platforms where boot parameters are difficult to employ (based on feedback by
      Jeremy Katz).

      [PATCH] selinux: change context_to_sid handling for no-policy case · 77782961
      Andrew Morton authored
      From: Stephen Smalley <sds@epoch.ncsc.mil>
      
      This patch changes the behavior of security_context_to_sid in the no-policy
      case so that it simply accepts all contexts and maps them to the kernel SID
      rather than rejecting anything other than an initial SID.  The change avoids
      error conditions when using SELinux in permissive/no-policy mode, so that any
      file contexts left on disk from prior use of SELinux with a policy will not
      cause an error when they are looked up and userspace attempts to set contexts
      can succeed.

      [PATCH] lockfs - xfs bits · 46f76939
      Andrew Morton authored
      From: Christoph Hellwig <hch@lst.de>
      
      Remove all the code now in the VFS, make XFS's freeze ioctls use the new
      infastructure and reorganize some code.
      
      This code needs some work so the source files shared with 2.4 aren't
      exposed to the new VFS interfaces directly.  You'll get an update once this
      has been discussed with the other XFS developers and is implemented.  Note
      that the current patch works fine and I wouldn't complain if it gets into
      Linus' tree as-is.

      [PATCH] lockfs - vfs bits · 137718ec
      Andrew Morton authored
      From: Christoph Hellwig <hch@lst.de>
      
      These are the generic lockfs bits.  Basically it takes the XFS freezing
      statemachine into the VFS.  It's all behind the kernel-doc documented
      freeze_bdev and thaw_bdev interfaces.
      
      Based on an older patch from Chris Mason.
