From mboxrd@z Thu Jan 1 00:00:00 1970 From: Latchesar Ionkov Subject: [PATCH] IB/core: Pass imm_data from ib_uverbs_send_wr to ib_send_wr correctly when sending UD messages Date: Sat, 19 Oct 2013 15:55:41 -0600 Message-ID: <20131019215540.GA8544@moria> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Content-Disposition: inline Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: linux-rdma@vger.kernel.org Currently, the infiniband subsystem doesn't copy the immediate data from the userspace struct to the kernel one when UD messages are being sent. This patch makes sure that the immediate data is set correctly.
