From mboxrd@z Thu Jan 1 00:00:00 1970 From: Leon Romanovsky Subject: [PATCH mlx5-next v1 6/7] net/mlx5: Set uid as part of DCT commands Date: Thu, 20 Sep 2018 21:35:25 +0300 Message-ID: <20180920183526.13995-7-leon@kernel.org> References: <20180920183526.13995-1-leon@kernel.org> Return-path: In-Reply-To: <20180920183526.13995-1-leon@kernel.org> Sender: netdev-owner@vger.kernel.org To: Doug Ledford , Jason Gunthorpe Cc: Leon Romanovsky , RDMA mailing list , Yishai Hadas , Saeed Mahameed , linux-netdev List-Id: linux-rdma@vger.kernel.org From: Yishai Hadas Set uid as part of DCT commands so that the firmware can manage the DCT object in a secured way. That will enable using a DCT that was created by verbs application to be used by the DEVX flow in case the uid is equal.
