Date: Thu, 6 Mar 2008 16:34:24 -0500 From: Allan Stephens <allan.stephens@...driver.com> To: David Miller <davem@...emloft.net> Cc: netdev@...r.kernel.org, allan.stephens@...driver.com Subject: [PATCH 2/7 net-2.6.26] [TIPC]: Add argument validation for shutdown() This patch validates that the "how" argument to shutdown() is SHUT_RDWR, since this is the only form that TIPC supports.
