Subject: v5.15-rc1 issue with the soft-iWARP driver
Date: Tue, 14 Sep 2021 21:54:27 -0700	[thread overview]
Message-ID: <> (raw)


If I run test srp/015 from the blktests suite then the following appears
in the kernel log:

BUG: KASAN: null-ptr-deref in __list_del_entry_valid+0x4d/0xe0
Read of size 8 at addr 0000000000000000 by task kworker/u16:3/161

CPU: 5 PID: 161 Comm: kworker/u16:3 Not tainted 5.15.0-rc1-dbg+ #2
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 04/01/2014
Workqueue: iw_cm_wq cm_work_handler [iw_cm]
Call Trace:
  _cma_cancel_listens+0x49/0x230 [rdma_cm]
  _destroy_id+0x4e/0x420 [rdma_cm]
  destroy_id_handler_unlock+0xc4/0x200 [rdma_cm]
  iw_conn_req_handler+0x335/0x370 [rdma_cm]
  cm_conn_req_handler+0x546/0x7d0 [iw_cm]
  cm_work_handler+0x419/0x480 [iw_cm]

I think this is a regression. This happened with commit a17a1faf5d3e
("RDMA/cma: Fix listener leak in rdma_cma_listen_on_all() failure").
