      Merge sys_clone()/sys_unshare() nsproxy and namespace handling · e3222c4e
      Badari Pulavarty authored
      sys_clone() and sys_unshare() both makes copies of nsproxy and its associated
      namespaces.  But they have different code paths.
      
      This patch merges all the nsproxy and its associated namespace copy/clone
      handling (as much as possible).  Posted on container list earlier for
      feedback.
      
      - Create a new nsproxy and its associated namespaces and pass it back to
        caller to attach it to right process.
      
      - Changed all copy_*_ns() routines to return a new copy of namespace
        instead of attaching it to task->nsproxy.
      
      - Moved the CAP_SYS_ADMIN checks out of copy_*_ns() routines.
      
      - Removed unnessary !ns checks from copy_*_ns() and added BUG_ON()
        just incase.
      
      - Get rid of all individual unshare_*_ns() routines and make use of
        copy_*_ns() instead.
