            Bug ID: 1306560
           Summary: Accessing program list in build_prog_details () should
                    be lock protected
           Product: GlusterFS
           Version: mainline
         Component: rpc
          Assignee: bugs at gluster.org

Description of problem:

Currently build_prog_details() iterates over the rpcsvc's program list and
constructs a local linked list. However the same happens with out any lock
protection and hence this can cause a crash if some other writer threads modify
the same list.
