Subject: [PATCH] multipath: fix systemd timers in the initramfs
The systemd timers created for "find_multipaths smart" conflict with
shutdown.target, but not with initrd-cleanup.service. This can make
these timers trigger after the inirtd has started shutting down,
restarting multipathd (which then stops initrd-cleanup.service, since it
conflicts). To avoid this, make sure the timers and the unit they
trigger conflict with inird-cleanup.service. Also don't make them start
multipathd. "multipath -u" will not return "maybe" if multipathd isn't
running or set to run, and since we no longer wait for udev-settle,
multipathd starts up pretty quickly, so it shouldn't be a problem to
not trigger it here.

Subject: [PATCH] multipathd: Handle losing all path in update_map
Its possible that when a multipath device is being updated, it will end
up that all the paths for it are gone. This can happen if paths are
added and then removed again before multipathd processes the uevent for
the newly created multipath device. In this case multipathd wasn't
taking the proper action for the case where all the paths had been
removed. If flush_on_last_del was set, multipathd wasn't disabling
flushing and if deferred_remove was set, it wasn't doing a deferred
remove. Multipathd should call flush_map_nopaths(), just like
ev_remove_path() does when the last path is removed.

Subject: [PATCH] multipath-tools: use /run instead of /dev/shm
/dev/shm may have unsafe permissions. Use /run instead.
Use systemd's tmpfiles.d mechanism to create /run/multipath
early during boot.
For backward compatibilty, make the runtime directory configurable
via the "runtimedir" make variable.

Subject: [PATCH] kpartx: hold device open until partitions have been created
kpartx was closing the whole device after it read the partition
information off it. This allowed a race, where the device could be
removed and another one created with the same major:minor, after kpartx
read the partition information but before it created the partition
devices.

Subject: [PATCH] libmultipath: cleanup remove_feature
remove_feature() didn't correctly handle feature strings that used
whitespace other than spaces, which the kernel allows. It also didn't
check if the feature string to be removed was part of a larger feature
token. Finally, it did a lot of unnecessary work. By failing if the
feature string to be removed contains leading or trailing whitespace,
the function can be significanly simplified.

Subject: [PATCH] libmultipath: cleanup add_feature
add_feature() didn't correctly handle feature strings that used
whitespace other than spaces, which the kernel allows. It also didn't
allow adding features with multiple tokens. When it looked to see if the
feature string to be added already existed, it didn't check if the match
was part of a larger token. Finally, it did unnecessary work. By using
asprintf() to create the string, the function can be signifcantly
simplified.

Subject: [PATCH] libmultipath: fix queue_mode feature handling
device-mapper is not able to change the queue_mode on a table reload.
Make sure that when multipath sets up the map, both on regular reloads
and reconfigures, it keeps the queue_mode the same.

Read the transport protocol from /sys/block/nvmeXnY/device/transport.
Update protocol_name[] and bus_protocol_id() to store the nvme protocol
names after the scsi protocol names.

Date: Fri, 7 Oct 2022 12:35:44 -0500
Subject: [PATCH] libmultipath: enforce queue_mode bio for nmve:tcp paths
nvme:tcp devices set BLK_MQ_F_BLOCKING (they are the only block devices
which multipath supports that do so), meaning that block_mq expects that
they can block at certain points while servicing a request. However,
due to the way device-mapper sets up its queue, it is not able to set
BLK_MQ_F_BLOCKING when it includes paths that set this flag. Patches
were written to address this issue but they were rejected upstream
https://lore.kernel.org/linux-block/YcH%2FE4JNag0QYYAa@infradead.org/T/#t
The proposed solution was to have multipath use the bio queue_mode for
multipath devices that include nvme:tcp paths.
Multipath devices now automatically add the "queue_mode bio" feature if
they include nvme:tcp paths. If a multipath devices was created with
"queue_mode rq", it will disallow the addition of nvme:tcp paths.

Subject: [PATCH] multipath.conf(5): remove io-affinity information
The multpath-tools do not support the io-affinity path selector. We
always add a repeat count as the path argument. The io-affinity selector
doesn't take one. Instead it takes a bit map of CPUs that a path can
run on. This isn't something that lends itself to the kind of
auto-assembling that multipathd does. But even if we did want to
try to support this path-selector, until we do, we shouldn't be listing
it in the multipath.conf documentation.

Subject: [PATCH] libmutipath: validate the argument count of config strings
The features, path_selector, and hardware_handler config options pass
their strings directly into the kernel. If users omit the argument
counts from these strings, or use the wrong value, the kernel's table
parsing gets completely messed up, and the error messages it prints
don't reflect what actully went wrong. To avoid messing up the
kernel table parsing, verify that these strings correctly set the
argument count to the number of arguments they have.

Subject: [PATCH] libmultipath: select resize action even if reload is forced
The ACT_RESIZE action is the same as the ACT_RELOAD action, except that
it flushes outstanding IO because the device size is changing and
the new size might be too small for some of the outstanding IO. If we've
detected a size change, and a forced reload is requested, we still need
to flush the IO because the reload will change the device size.

Subject: [PATCH] libmultipath: keep renames from stopping other multipath
actions
If select_action() is called and a multipath device needs to be renamed,
the code currently checks if force_reload is set, and if so, does the
reload after the rename. But if force_reload isn't set, only the rename
happens, regardless of what other actions are needed. This can happen if
multipathd starts up and a device needs both a reload and a rename.
Make multipath check for resize, reload, and switch pathgroup along with
rename, and do both if necessary.

Subject: [PATCH] multipath.rules: fix "smart" bug with failed valid path check
If "multipath -u" fails, udev doesn't import any values from the
program. This means that multipath.rules will continue to use the values
for DM_MULTIPATH_DEVICE_PATH and FIND_MULTIPATHS_WAIT_UNTIL that it has
already imported from the database. This is the correct thing to do for
every case except the MAYBE case for "find_multipaths smart". In that
case, DM_MULTIPATH_DEVICE_PATH will be set to 1, and the rules will
assume that the device has been definitively claimed.
In this case, we know that the device shouldn't have been claimed
before, but we don't know if it should be claimed now, or if we have hit
the timeout and it should be released, since we didn't get any
information from multipath. The safest thing to do is assume that this
was the timeout, and the device shouldn't be claimed. The only time when
this could be the wrong answer is when we first see a new multipath
device, and it could only cause problems if there is metadata on the
device that will cause it to get autoassembled by something else, before
multipathd can autoassemble it. If we assume that it is a multipath
device, or we assume that this wasn't actually the timeout uevent, we
can keep a necessary device from getting released to the reset of the
system.

Subject: [PATCH] libmultipath: limit paths that can get wwid from environment
Currently, whenever getting the uid_attribute from udev database fails,
multipath will try to get it from the environment variables. This
normally isn't a problem, since either multipath -u is getting called
from a uevent, and the environment will have the correct value in that
variable, or that variable won't be set. However, when find_multipaths
is configured to "smart", this causes problems. For maybe devices,
multipath needs to get the WWIDs of all the other block devices, to see
if they match the maybe device wwid. If one of those devices doesn't
have uid_attribute set in its udev database, multipath will check the
environment for it, and it will find that variable set to the WWID
of the maybe device that this uevent is for. This means that all
devices with no WWID will end up appearing to have the same WWID as
the maybe device, causing multipath to incorrectly claim it.
