        [CIFS] Avoid open on possible directories since Samba now rejects them

      [CIFS] Avoid open on possible directories since Samba now rejects them · 8db14ca1
      Steve French authored
      Small change (mostly formatting) to limit lookup based open calls to
      file create only.
      After discussion yesteday on samba-technical about the posix lookup
      regression,  and looking at a problem with cifs posix open to one
      particular Samba version, Jeff and JRA realized that Samba server's
      behavior changed in this area (posix open behavior on files vs.
      directories).   To make this behavior consistent, JRA just made a
      fix to Samba server to alter how it handles open of directories (now
      returning the equivalent of EISDIR instead of success). Since we don't
      know at lookup time whether the inode is a directory or file (and
      thus whether posix open will succeed with most current Samba server),
      this change avoids the posix open code on lookup open (just issues
      posix open on creates).    This gets the semantic benefits we want
      (atomicity, posix byte range locks, improved write semantics on newly
      created files) and file create still is fast, and we avoid the problem
      that Jeff noticed yesterday with "openat" (and some open directory
      calls) of non-cached directories to one version of Samba server, and
      will work with future Samba versions (which include the fix jra just
      pushed into Samba server).  I confirmed this approach with jra
      yesterday and with Shirish today.
      Posix open is only called (at lookup time) for file create now.
      For opens (rather than creates), because we do not know if it
      is a file or directory yet, and current Samba no longer allows
      us to do posix open on dirs, we could end up wasting an open call
      on what turns out to be a dir. For file opens, we wait to call posix
      open till cifs_open.  It could be added here (lookup) in the future
      but the performance tradeoff of the extra network request when EISDIR
      or EACCES is returned would have to be weighed against the 50%
      reduction in network traffic in the other paths.
