From 1f11a7610e50982150b90b31d1f749f6217fbde6 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Sat, 3 Oct 2020 20:20:08 -0300 Subject: RDMA: Check create_flags during create_qp Each driver should check that the QP attrs create_flags is supported. Unfortuantely when create_flags was added to the QP attrs the drivers were not updated. uverbs_ex_cmd_mask was used to block it - even though kernel drivers use these flags too. Check that flags is zero in all drivers that don't use it, remove IB_USER_VERBS_EX_CMD_CREATE_QP from uverbs_ex_cmd_mask. Fix the error code to be EOPNOTSUPP.
