-------- Forwarded Message -------- Subject: Possible bug in test_mr.py Date: Sun, 28 Mar 2021 22:52:01 -0500 From: Bob Pearson <rpearsonhpe@xxxxxxxxx> To: Jason Gunthorpe <jgg@xxxxxxxxxx>, Zhu Yanjun <zyjzyj2000@xxxxxxxxx>, linux-rdma@xxxxxxxxxxxxxx Testing ibv_rereg_mr() I noticed that the test uses the rkey originally assigned to the MR by ibv_reg_mr() and not the rkey subsequently assigned after calling ibv_rereg_mr(). This matters when the original MR did not have remote memory access and rkey was set to zero. If the rereg changes access to allow remote memory access then the rkey is set when the verb returns. But the test code never looks again after setting up the original MRs. In rxe setting rkey = lkey always gets the first rereg test case to pass. bob
