      NFS: Add deferred cache invalidation for close-to-open consistency violations · 1c341b77
      Trond Myklebust authored
      If the client detects that close-to-open cache consistency has been
      violated, and that the file or directory has been changed on the
      server, then do a cache invalidation when we're done working with
      the file.
      The reason we don't do an immediate cache invalidation is that we
      want to avoid performance problems due to false positives. Also,
      note that we cannot guarantee cache consistency in this situation
      even if we do invalidate the cache.

      NFSv4: Handle the special Linux file open access mode · 44942b4e
      Trond Myklebust authored
      According to the open() manpage, Linux reserves the access mode 3
      to mean "check for read and write permission on the file and return
      a file descriptor that can't be used for reading or writing."
      
      Currently, the NFSv4 code will ask the server to open the file,
      and will use an incorrect share access mode of 0. Since it has
      an incorrect share access mode, the client later forgets to send
      a corresponding close, meaning it can leak stateids on the server.

      NFSv4: Handle open for execute correctly · 1bf85d8c
      Trond Myklebust authored
      When mapping the NFSv4 context to an open mode and access mode,
      we need to treat the FMODE_EXEC flag differently. For the open
      mode, FMODE_EXEC means we need read share access. For the access
      mode checking, we need to verify that the user actually has
      execute access.

         - Fix a silly typo in virt_addr_valid which led to completely bogus

           behavior of scripts/package/builddeb.
      
         - Handle an execution hazard in TLB exceptions that use KScratch
           registers, which could inadvertently clobber the $1 register on
           some generally higher-end out-of-order CPUs.
