      fanotify: Fix use after free for permission events · 85816794
      Jan Kara authored
      Currently struct fanotify_event_info has been destroyed immediately
      after reporting its contents to userspace. However that is wrong for
      permission events because those need to stay around until userspace
      provides response which is filled back in fanotify_event_info. So change
      to code to free permission events only after we have got the response
      from userspace.

      fsnotify: Do not return merged event from fsnotify_add_notify_event() · 83c0e1b4
      Jan Kara authored
      The event returned from fsnotify_add_notify_event() cannot ever be used
      safely as the event may be freed by the time the function returns (after
      dropping notification_mutex). So change the prototype to just return
      whether the event was added or merged into some existing event.

      fanotify: Fix use after free in mask checking · 13116dfd
      Jan Kara authored
      We cannot use the event structure returned from
      fsnotify_add_notify_event() because that event can be freed by the time
      that function returns. Use the mask argument passed into the event
      handler directly instead. This also fixes a possible problem when we
      could unnecessarily wait for permission response for a normal fanotify
      event which got merged with a permission event.
      
      We also disallow merging of permission event with any other event so
      that we know the permission event which we just created is the one on
      which we should wait for permission response.

      ceph: Fix up after semantic merge conflict · 4db658ea
      Linus Torvalds authored
      The previous ceph-client merge resulted in ceph not even building,
      because there was a merge conflict that wasn't visible as an actual data
      conflict: commit 7221fe4c ("ceph: add acl for cephfs") added support
      for POSIX ACL's into Ceph, but unluckily we also had the VFS tree change
      a lot of the POSIX ACL helper functions to be much more helpful to
      filesystems (see for example commits 2aeccbe9 "fs: add generic
      xattr_acl handlers", 5bf3258f "fs: make posix_acl_chmod more useful"
      and 37bc1539 "fs: make posix_acl_create more useful")
      
      The reason this conflict wasn't obvious was many-fold: because it was a
      semantic conflict rather than a data conflict, it wasn't visible in the
      git merge as a conflict.  And because the VFS tree hadn't been in
      linux-next, people hadn't become aware of it that way.  And because I
      was at jury duty this morning, I was using my laptop and as a result not
      doing constant "allmodconfig" builds.
      
      Anyway, this fixes the build and generally removes a fair chunk of the
      Ceph POSIX ACL support code, since the improved helpers seem to match
      really well for Ceph too.  But I don't actually have any way to *test*
      the end result, and I was really hoping for some ACK's for this.  Oh,
      well.
      
      Not compiling certainly doesn't make things easier to test, so I'm
      committing this without the acks after having waited for four hours...
      Plus it's what I would have done for the merge had I noticed the
      semantic conflict..

      mtd: gpmi: add sanity check when mapping DMA for read_buf/write_buf · 0ff76a92
      Huang Shijie authored
      The buffer pointer passed from the upper layer may points to
      a buffer in the stack or a buffer allocated by vmalloc, and etc..
      
      This patch adds more sanity check to this buffer.
      After this patch, if we meet a buffer which is allocated by vmalloc or
      a buffer in the stack, we will use our own DMA buffer @data_buffer_dma
      to do the DMA operations. If the buffer is not the cases above, we will
      map it for DMA operations directly.
