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.

Subject: [PATCH] libmultipath: get nvme path transport protocol
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] libmultipath: copy mpp->hwe from pp->hwe
Since f0462f0 ("libmultipath: use vector for for pp->hwe and mp->hwe"),
we've been trying to fix issues caused by paths getting freed and mpp->hwe
dangling. This approach couldn't work because we need mpp->hwe to persist,
even if all paths are removed from the map. Before f0462f0, a simple
assignment worked, because the lifetime of the hwe wasn't bound to the
path. But now, we need to copy the vector. It turns out that we need to set
mpp->hwe only in two places, add_map_with_path() and setup_map(), and
that the code is simplified overall.
Even now, it can happen that a map is added with add_map_without_paths(),
and has no paths. In that case, calling do_set_from_hwe() with a NULL
pointer is not a bug, so remove the message.
Fixes: f0462f0 ("libmultipath: use vector for for pp->hwe and mp->hwe")

If set_path() or set_str_noslash() are called with a bad value, they
ignore it and continue to use the old value. But they weren't freeing
the bad value, causing a memory leak.

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.
