    Description

      The command:

      lctl --net tcp push

      will cause a host with any active lustre connections to crash.  Code in ksocknal_push() has an incorrect termination condition and falls off the end of a linked lists, dereferencing an invalid pointer.

      Precise results vary.  e.g. an LASSERT failure in ksocknal_connsock_addref(), or a NULL pointer dereference.
