From fa20105e09e97e81aadf02f722c31195e4a75c84 Mon Sep 17 00:00:00 2001 From: Guy Shapiro Date: Thu, 22 Oct 2015 15:20:10 +0300 Subject: IB/cma: Add support for network namespaces Add support for network namespaces in the ib_cma module. This is accomplished by: 1. Adding network namespace parameter for rdma_create_id. This parameter is used to populate the network namespace field in rdma_id_private. rdma_create_id keeps a reference on the network namespace. 2. Using the network namespace from the rdma_id instead of init_net inside of ib_cma, when listening on an ID and when looking for an ID for an incoming request. 3. Decrementing the reference count for the appropriate network namespace when calling rdma_destroy_id. In order to preserve the current behavior init_net is passed when calling from other modules.
