PATCH 1/1 Revert "dm mpath: remove unnecessary NVMe branching in favor of scsi_dh checks"

This patch fixes the following kernel crash:

INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.

Fixes 8d47e65948dd ("dm mpath: remove unnecessary NVMe branching in favor of scsi_dh checks")
Signed-off-by Bart Van Assche <[email protected]>

Sorry for your troubles but reverting isn't the proper way to handle this (yet).

Could you provide more details on your setup?

Obviously you're using "queue_mode mq", what are your underlying paths?

Given the trace it would seem you're hitting multipath_clone_and_map()'s blk_queue_dying(q) error path that calls activate_or_offline_path().

Would be useful to know the crash utility's output for:
dis -l pg_init_done+0x100

But I'd imagine it isn't happy here:
wake_up(&m->pg_init_wait);

Given the commit in question, I am assuming there is something about this setup_scsi_dh() code that is causing m->pg_init_wait to not be initialized:

                        /*
                         * Init fields that are only used when a scsi_dh is attached
                         */
                        if (!test_and_set_bit(MPATHF_QUEUE_IO, &m->flags)) {
                                atomic_set(&m->pg_init_in_progress, 0);
                                atomic_set(&m->pg_init_count, 0);
                                m->pg_init_delay_msecs = DM_PG_INIT_DELAY_DEFAULT;
                                init_waitqueue_head(&m->pg_init_wait);
                        }

Wonder if having made that initialization conditional is the culprit... that was needed because setup_scsi_dh() is called multiple times now. Whereas before this commit it was only done once as part of the initial multipath table load (in alloc_multipath_stage2).

I'll keep looking at this.

Hello Mike,

The reported kernel crash was triggered by running the following command:

srp-test/run_tests -c -d -r 10 -t 02-mq

The srp-test software is available at https://github.com/bvanassche/srp-test.
All patches necessary to run that script in a virtual machine (RoCE support for the SRP initiator and target drivers) will be sent to Linus during the kernel v4.17 merge window. These patches are already available in linux-next today. Although I have not tried this myself, I expect that if you run the above command against a kernel built from the linux-next code that that will allow you to reproduce what I reported.

Thanks,

Bart.

OK, that test again. I clearly need to invest time to making it run on my testbed. But that will take time (though hopefully I can cut through it tomorrrow).

Anyway, I'm hopeful I fixed the issue you reported. Please feel free to test the 2 topmost commits I've staged in linux-next, via dm-4.16:

So far I haven't seen the crash I reported yesterday in my tests with dm-4.16 of this morning. But I see hanging dm requests. I did not see any such issue yesterday with the revert I posted applied on top of dm-4.16. What I see today in the logs is the following:

Anyway, I'm hopeful I fixed the issue you reported. Please feel free to test the 2 topmost commits I've staged in linux-next, via dm-4.16:
https://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git/log/?h=dm-4.16
So far I haven't seen the crash I reported yesterday in my tests with dm-4.16 of this morning. But I see hanging dm requests. I did not see any such issue yesterday with the revert I posted applied on top of dm-4.16. What I see today in the logs is the following:

Just a thought: Maybe dm-4.16 (rc4 based) is missing a blk-mq fix?

Might be worth cherry-picking the 2 topmost commits from dm-4.16 into the linus-based (rc5) tree you reported the original issue against?

(looking at jens' rc5 block pull request, it seems unlikely but...)

Hello Mike,

Even if that would be the case, that can't have been the cause of what I reported. Before I run any dm tests I merge the block layer, SCSI and RDMA changes that are scheduled for the next kernel version into the dm tree.

Hello Mike,

Well I've rebased dm-4.16 ontop of v4.15-rc5. If you udate to latest dm-4.16 and look at the following diff it is pretty clear that these changes will not compromise dm-mpath's "mq" mode (which you're using):

git diff 8d47e65948ddea4398892946d9e50778a316b397^..e8f74a0f00113d74ac18d6de13096f9e2f95618a -- drivers/md/dm-mpath.c

I see no reason why you'd hit hangs with requests lingering on the requeue_list

Hello Mike,

I agree with you that the hanging requests shouldn't be related to the most recent dm changes. I will try to find some time to root-cause this myself.

Could you provide more details on your setup?
Obviously you're using "queue_mode mq", what are your underlying paths?
Given the trace it would seem you're hitting multipath_clone_and_map()'s blk_queue_dying(q) error path that calls activate_or_offline_path().
Hello Mike,
The reported kernel crash was triggered by running the following command:
srp-test/run_tests -c -d -r 10 -t 02-mq

Quoted 7 lines

The srp-test software is available at https://github.com/bvanassche/srp-test.
All patches necessary to run that script in a virtual machine (RoCE support for the SRP initiator and target drivers) will be sent to Linus during the kernel v4.17 merge window. These patches are already available in linux-next today. Although I have not tried this myself, I expect that if you run the above command against a kernel built from the linux-next code that that will allow you to reproduce what I reported.

A pointer to the commit ids in question would be helpful so I can appreciate the details better.

Why is there need for a virtual machine?
Just using extra isolation so as not to conflict with anything on the host?

Anyway, I followed srp-test's README.md

But sadly, today's linux-next (next-20180313) is a mess (lots of macro expansion breakage, for me anyway).

But I realized that was with an old srp-test build.. so I tried to make again.. seems your buildrequires has expanded:

Why does it need shellcheck? On RHEL, having to pull in EPEL packages sucks.

And even once installed via EPEL (so ShellCheck-0.3.5-1.el7.x86_64):

# make
...
shellcheck -x -f gcc run_tests bin/getuid_callout lib/functions \
tests/*[^~]

  -V                --version                Print version information

make: *** [shellcheck] Error 3

In general this srp-test suite is way too exotic with its requirements. Barrier to entry from a dumb user like me is _way_ too high.

That's weird. I will see whether I can reproduce this with linux-next, since I have not yet tried to run srp-test against linux-next myself.

But I realized that was with an old srp-test build.. so I tried to make again.. seems your buildrequires has expanded:
Why does it need shellcheck? On RHEL, having to pull in EPEL packages sucks.

Shellcheck is only required for someone who wants to edit the srp-test scripts and who wants to verify these scripts with shellcheck. Shellcheck is not needed to run the srp-test scripts.

That's weird. I will see whether I can reproduce this with linux-next, since I have not yet tried to run srp-test against linux-next myself.

OK, I appreciate it (you'll need to revert thos commits I shared in the other linux-next thread).

Hello Mike,

The bug that caused this failure has been fixed and is in linux-next. The srp-test software runs fine on my setup against linux-next. See also

A pointer to the commit ids in question would be helpful so I can appreciate the details better.

Not sure whether this list is complete, but this is the most important one:

Why is there need for a virtual machine?
Just using extra isolation so as not to conflict with anything on the host?

Running these tests directly on the host is also fine. I wanted to explain that no InfiniBand hardware is required.

Bart.
