Subject: blktests failures with v7.1-rc1 kernel
Date: Tue, 28 Apr 2026 18:13:17 +0900 [thread overview]
Message-ID: <afB5syZbUrppgsDQ@shinmob> (raw)
Hi all,
I ran the latest blktests (git hash: ea5472c1adc8) with the v7.1-rc1 kernel. I
observed 8 failures listed below. Comparing with the previous report for the
v7.0 kernel [1], 2 failures are new (nvme/045, scsi/002). Your actions for fix
will be welcomed as always.
[1] https://lore.kernel.org/linux-block/aeCDXI5hY_ivSWm4@shinmob/
List of failures
================
#1: nvme/005,063 (tcp transport)
#2: nvme/045 (new)(kmemleak)
#3: nvme/058 (fc transport)(hang)(kmemleak)
#4: nvme/060
#5: nvme/061 (rdma transport, siw driver)(kmemleak)
#6: nvme/061 (fc transport)
#7: nbd/002
#8: scsi/002 (new)
Failure description
===================
#1: nvme/005,063 (tcp transport)
The test cases nvme/005 and 063 fail for tcp transport due to the lockdep
WARN related to the three locks q->q_usage_counter, q->elevator_lock and
set->srcu. The failure was reported first time for nvme/063 and v6.16-rc1
kernel [2].
Chaitanya provided a fix patch (thanks!), and it is queued for v7.1-rcX tags
[3]. However, nvme/005 and 063 still fail even when I apply the fix patch to
v7.1-rc1 kernel. The call traces of the lockdep WARN are different between
"v7.1-rc1" kernel [4] and "v7.1-rc1+the fix patch" kernel [5]. I guess that
there exist two lockdep problems with similar symptoms and patch [3] fixed
one of them. I guess that still one problem is left.

#2: nvme/045 (new)(kmemleak)
When the test case nvme/045 is repeated twice for any transport on the
kernel with CONFIG_DEBUG_KMEMLEAK enabled, it causes kmemleak. The 2nd
run does not fail but records the kmemleak in results/start.kmemleak [6].
#3: nvme/058 (fc transport)(kmemleak)
When the test case nvme/058 is repeated for fc transport, it fails or hangs.
When the hang happens, a lockdep WARN and a "BUG: null pointer dereference"
are reported [7]. I reported similar hang for v7.0-rc1 kernel [8], but did
not observe if for v7.0 kernel, probably because the hang is sporadic.
When the kernel enables CONFIG_DEBUG_KMEMLEAK, the test case sometimes
causes kmemleak. Due to the hang, kmemleak recreation is rather difficult.
When it happens, it does not reported as failure of the test case, but
recorded in results/start.kmemleak. The memory leak report looks similar as
those I reported for v7.0-rc1 kernel [8].
[8] https://lore.kernel.org/linux-block/aZ_-cH8euZLySxdD@shinmob/
#4: nvme/060 (rdma transport)
When the test case is repeated for rdma transport around 50 times, the test
case fails. As reported for v7.0 kernel, there are two failure symptoms [1].
Both symptoms do not look kernel side problems, but blktests side problems.
I will allocate time to look into them.
#5: nvme/061 (rdma transport, siw driver)(kmemleak)
When the test case nvme/061 is repeated twice for the rdma transport and the
siw driver on the kernel v6.19 with CONFIG_DEBUG_KMEMLEAK enabled, it causes
kmemleak that is detected at the beginning of the 2nd run. Refer to the
nvme/061 failure report for v6.19 kernel [9].
[9] https://lore.kernel.org/linux-block/aY7ZBfMjVIhe_wh3@shinmob/
#6: nvme/061 (fc transport)
When the test case nvme/061 is repeated around 50 times for the fc
transport, the test process fails after Oops and KASAN null-ptr-deref. It
had hanged with v7.0-rc1 kernel. I did not observed the hang with v7.0
kernel by some reason, but it was observed with v7.1-rc1 kernel again.
Refer to the report for the v7.0-rc1 kernel [8].
#7: nbd/002
The test case nbd/002 fails due to the lockdep WARN related to
sk_lock-AF_INET6, cmd->lock and nsock->txlock [9]. The lockdep WARN of this
test case has been reported since v6.18-rc1 kernel [10]. In the past,
related locks were mm->mmap_lock, sk_lock-AF_INET6 and fs_reclaim, which are
different from those are observed with the v7.1-rc1 kernel.
[10] https://lore.kernel.org/linux-block/ynmi72x5wt5ooljjafebhcarit3pvu6axkslqenikb2p5txe57@ldytqa2t4i2x/
#8: scsi/002
The test case fails with the message below. The failure cause is sg node
file open failure. A fix patch is already queued for v7.1-rcX tags [11].
