Bug #11225: r50776 + r50780 + r50781 changes behavior on systems without HAVE_STRUCT_MSGHDR_MSG_CONTROL

[ngoto (Naohisa Goto)]

On systems without HAVE_STRUCT_MSGHDR_MSG_CONTROL such as Solaris 10,
when passing 3 or more arguments to rsock_bsock_sendmsg and rsock_bsock_sendmsg_nonblock that internally call bsock_sendmsg_internal,

r50775 or before: NotImplementedError is raised as follows.

	rb_raise(rb_eNotImpError, "control message for sendmsg is unimplemented");

after r50776: ArgumentError is raised in rb_scan_args(argc, argv, "12", ...)

I think the behavior change is not intended.

• Status changed from Open to Closed

Applied in changeset r50784.

---

• ext/socket/ancdata.c (bsock_sendmsg_internal): all arguments are
  parsed even on systems without HAVE_STRUCT_MSGHDR_MSG_CONTROL
  to prevent SEGV caused by passing Qnil to RARRAY_LENINT and
  to preserve behavior before r50776.
