The following patch introduces an annoying WARN
when a device is removed from the SAS topology:
[SCSI] libsas: prevent domain rediscovery competing with ata error handling
A sample WARN is as follows:

(this can be really huge when an expander is unplugged)
The problem is with the process of sas_port and domain_device
destruction in domain revalidation. There is a 2-stage process:
In domain revalidation (which runs in work queue context), if a
domain_device is discovered to be gone, then the following happens:
- the domain_device is queued for destruction in a separate work item
- the associated sas_port is destroyed immediately
This causes a problem in that the sas_port associated with
a domain_device is destroyed prior the domain_device: this causes
the sysfs WARN. Essentially the "rug has been pulled from underneath".
Also, likewise, when a root port is deformed due to loss of signal,
we have the same issue.
To solve, destroy the sas_port in a separate work item to which
we do the domain revalidation with a new discovery event, as follows:
- When a domain_device is detected to be gone, the domain_device is
queued for destruction in a separate work item. The associated
sas_port is also queued for destruction in another separate work item
(needs to be queued 2nd)
- the domain_device is destroyed
- the sas_port is destroyed
[similar is done for loss of signal event, in sas_port_deformed()].

rediscovery competing with ata error handling

Are there any views on this patch? I would have thought that the parties
who use the drivers based on libsas would be interested in fixing this bug.
BTW, We are internally testing, hence the RFC.
Thanks in advance,

I should have added the before and after logs earlier, so the issue is
illustrated. Now attached. When a 24-port expander is unplugged we get

BTW, We are internally testing, hence the RFC.

I might be mistaken, but this patch seems functionally identical to
this attempt:
http://marc.info/?l=linux-scsi&m=143459794823595&w=2
i.e. it moves the port destruction to the workqueue and still suffers
from the flutter problem:
http://marc.info/?l=linux-scsi&m=143801026028006&w=2
http://marc.info/?l=linux-scsi&m=143801971131073&w=2
Perhaps we instead need to quiet this warning?

Alternatively we need a mechanism to cancel in-flight port shutdown
requests when we start re-attaching devices before queued port
destruction events have run.

Hi Dan,
They're not the same. I don't see how your solution properly deals with
remote sas_port deletion.
When we unplug a device connected to an expander, can't the sas_port be
deleted twice, in sas_unregister_devs_sas_addr() from domain
revalidation and also now in sas_destruct_devices()? I think that this
gives a NULL dereference.
And we still get the WARN as the sas_port has still been deleted before
the device.
In my solution, we should always delete the sas_port after the attached
device.

I have not seen the flutter issue. I am just trying to solve the
horrible WARN dump.
However I do understand that there may be a issue related to how we
queue the events; there was a recent attempt to fix this, but it came to
nothing:

We found libsas hotplug several problems:
1. sysfs warning calltrace(like the case you found);
2. hot-add and hot-remove work events may process out of order;
3. in some extreme cases, libsas may miss some events, if the same event is still pending in workqueue.
It's a complex issue, we posted two patches, try to fix these issues, but now few people are interested in it :(

IIRC, you sent as RFC and got a "reviewed-by" from Hannes, so I'm not
sure what else you want. BTW, I thought that the changes were quite drastic.

I did it, I think your solution to fix the sysfs calltrace issue is ok, and what I worried about is we still need to fix
the rest issues. So it's better if we could fix all issues one time.

Qilin Chen and Yousong He help me to reproduce it, I told them to reply this mail to tell you the test steps.
Some tests we did is make sas phy link flutter, so hardware would post phy down and phy up events sequentially.
1. scsi host workqueue receive phy down and phy up events. in process new added
2. sas_deform_port would post a new destruct event to scsi host workqueue, so things in workqueue like [phy down-----phy up -----destruct]
So the phy down logic is separated by phy up, and it's not atomic, not safe, something unexpected would happen.
For case 3, we make hardware burst post lots pair of phy up and phy down events, so if libsas is processing the phy up event, the next
phy up event can not queue to scsi host workqueue again, it will lost, it's not we expect.

I agree, the changes seems something drastic. But I think current libsas hotplug framework has a big flaw.

To me this adds a bug to quiet a benign, albeit noisy, warning.

What is the bug which is being added?
And it's a very noisy warning, as in 6K lines on the console when an
expander is unplugged.

The bug where we queue a port teardown, but see a port formation event

Does something like this modulate the failure?

As I understand, this vulnerability already exists:
http://marc.info/?l=linux-scsi&m=143801026028006&w=2
I actually don't understand how libsas dealt with flutter (which I take
to mean a burst of up and down events) before these changes, as it can
only queue simultaneously one up and one down event per port. So, if we
get a flutter, then the events are lost and we get indeterminate state.

The events are not lost. The new problem this patch introduces is
delaying sas port deletion where it was previously immediate. So now
we can get into a situation where the port has gone down and can start
processing a port up event before the previous deletion work has run.

In sas_queue_event(), if there is a particular event pending for a
port/PHY, we cannot queue further same event types for that port/PHY. I
think my colleagues found issue where we try to enqueue multiple
complementary events.

No, I just tested it on a root port and we get the same WARN.
