Subject: [PATCH] libmultipath: keep track of queueing state in features
Make multipathd update mpp->features when in enables or disables
queuing. This patch handles all the cases except failed removes by
dm_suspend_and_flush_map(), which is never called by multipathd.

Subject: [PATCH] libmultipath: change flush_on_last_del to fix a multipathd
hang
Commit 9bd3482e ("multipathd: make flush_map() delete maps like the
multipath command") fixed an issue where deleting a queueing multipath
device through multipathd could hang because the multipath device had
outstanding IO, even though the only openers of it at the time of
deletion were the kpartx partition devices. However it is still possible
to hang multipathd, because autoremoving the device when all paths have
been deleted doesn't disable queueing. To reproduce this hang:
1. create a multipath device with a kpartx partition on top of it and
no_path_retry set to either "queue" or something long enough to run all
the commands in the reproducer before it disables queueing.
2. disable all the paths to the device with something like:
# echo offline > /sys/block/<path_dev>/device/state
3. Write directly to the multipath device with something like:
# dd if=/dev/zero of=/dev/mapper/<mpath_dev> bs=4K count=1
4. delete all the paths to the device with something like:
# echo 1 > /sys/block/<path_dev>/device/delete
Multipathd will hang trying to delete the kpartx device because, as the
last opener, it must flush the multipath device before closing it.
Because it hangs holding the vecs_lock, multipathd will never disable
queueing on the device, so it will hang forever, even if no_path_retry
is set to a number.
This hang can occur, even if deferred_remove is set. Since nothing has
the kpartx device opened, device-mapper does an immediate remove, which
will still hang. This means that even if deferred_remove is set,
multipathd still cannot delete a map while queueing is enabled. It must
either disable queueing or skip the autoremove.
Mulitpath can currently be configured to avoid this hang by setting
flush_on_last_del yes
However there are good reasons why users wouldn't want to set that. They
may need to be able to survive having all paths getting temporarily
deleted. I should note that this is a pretty rare corner case, since
multipath automatically sets dev_loss_tmo so that it should not trigger
before queueing is disabled.
This commit avoids the hang by changing the possible values for
flush_on_last_del to "never", "unused", and "always", and sets the
default to "unused". "always" works like "yes" did, "never" will not
disable queueing, and "unused" will only disable queueing if nothing has
the kpartx devices or the multipath device open. In order to be safe, if
the device has queue_if_no_paths set (and in case of "unused", the
device is in-use) the autoremove will be skipped. Also, instead of just
trusting the lack of "queue_if_no_paths" in the current mpp->features,
multipathd will tell the kernel to disable queueing, just to be sure it
actually is.
I chose "unused" as the default because this should generally only cause
multipathd to work differently from the users perspective when nothing
has the multipath device open but it is queueing and there is
outstanding IO. Without this change, it would have hung instead of
failing the outstanding IO. However, I do understand that an argument
could be made that "never" makes more sense as default, even though it
will cause multipathd to skip autoremoves in cases where it wouldn't
before. The change to the behavior of deffered_remove will be
noticeable, but skipping an autoremove is much better than hanging.

Subject: [PATCH] libmultipath: pad dev_loss_tmo to avoid race with
no_path_retry
Currently multipath makes sure that dev_loss_tmo is at least as long as
the configured no path queueing time. The goal is to make sure that path
devices aren't removed while the multipath device is still queueing in
hopes that they will become usable again.
This is racy. Multipathd may take longer to check the paths than
configured. If strict_timing isn't set, it will definitely take longer.
To account for this, pad the minimum dev_loss_tmo value by five seconds
(one default checker interval) plus one second per minute of no path
queueing time.

Subject: [PATCH] libmultipath: change the vend/prod/rev printing
The %s multipath and path wildcards both say they print the device
vend/prod/rev string, but neither of them do. The multipath wildcards
already provide a way to print the revision string and the %s wildcard
is used in the multipath -l output, so leave the wildcard output alone,
and change the description to only mention the vendor and product. There
is no other way to print the revision by path, and the path %s wildcard
is only used in the verbose multipath output, so make it actually print
the revision. Also check for unset strings, and print "##" instead of
nothing.
