Ilya DryomovandGreg Kroah-Hartman 91542d131b ceph: validate snapdirname option length when mounting ...

commit 12eb22a5a6 upstream.

It becomes a path component, so it shouldn't exceed NAME_MAX
characters.  This was hardened in commit c152737be2 ("ceph: Use
strscpy() instead of strcpy() in __get_snap_name()"), but no actual
check was put in place.
