Subject: v5.14 RXE driver broken?
Date: Mon, 23 Aug 2021 20:01:03 -0700	[thread overview]

Hi Bob,

If I run the following test against Linus' master branch then that test
passes (commit d5ae8d7f85b7 ("Revert "media: dvb header files: move some
headers to staging"")):

# export use_siw=1 && modprobe brd && (cd blktests && ./check -q srp/002)
srp/002 (File I/O on top of multipath concurrently with logout and login (mq)) [passed]
    runtime    ...  48.849s

The following test fails:

# export use_siw= && modprobe brd && (cd blktests && ./check -q srp/002)
srp/002 (File I/O on top of multipath concurrently with logout and login (mq)) [failed]
    runtime  48.849s  ...  15.024s

     Configured SRP target driver

The only difference between these two tests is that test (1) use the siw
(soft-iWARP) driver while test (2) uses the rdma_rxe driver (soft-RoCE).
Both tests run reliably against previous Linux kernel versions, e.g.
v5.13. Can you take a look at this? The blktests software is available at
https://github.com/osandov/blktests/.

Thanks,

Bart.
