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")

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.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] multipathd: make pr registration consistent
multipathd was inconsistent on what it did with persistent reservations
when a multipath device was created. If a multipath device with a
configured reservation key was created during configure(), multipathd
would try to read the registered keys using an active path. If it saw a
matching key, it would set the prflag, but not attempt to register the
key on any of the other paths. This means that if a new path had
appeared while multipathd was not running, it wouldn't register the key
on this path.
If the multipath device was created during ev_add_path(), multipathd
would used the added path to check if there was a matching key and if
there was, register the key only on the added path and then set the
prflag. This could be problematic if the device was created with
multiple paths, for instance because find_mutipaths was set to "yes" and
a second path just appeared. In this case, if the device happened to be
only registered on the second path, it would not get registered on the
first path.
If the multipath device was added to multipathd during a call to
ev_add_map(), multipathd wouldn't set the prflag or register the key on
any paths.
After a device was created with the prflag set, if a new path appeared
before the creation uevent, and multipathd was forced to delay adding
it, when it finally updated the multipath device, the key would be
registered on all paths, fixing any paths missed during creation.
However, if a new path appeared after the creation uevent, the key would
only be registered on that new path. Any paths that were missed on
creation would stay missed.
persistent key registration needs to be handled consistently. This
patch does so by making sure that however a multipath device is added to
multipathd, it will check to see if the configured key is registered. If
it is, multipathd will set the prflag and register the key on all the
currently active paths.
When a new path is added, multipathd will use it to check for active
keys, as before. But if it finds a matching key and prflag isn't
currently set, it will register the key on all paths.

Subject: [PATCH] multipathd: handle no active paths in update_map_pr
When a multipath device is first created, if it has a reservation key
configured, update_map_pr() will check for a matching key on the active
paths. If there were no active paths to check with, multipathd was
leaving mpp->prflag in PRFLAG_UNSET, as if there were no matching keys.
It's possible that when update_map_pr() is called, all the paths will be
in the PATH_PENDING state because the checkers haven't completed yet. In
this case, multipathd was treating the device as having no registered
keys without ever checking.
To solve this, multipath devices now start with prflag = PRFLAG_UNKNOWN.
It will remain in this state until multipathd actually tries to get the
registered keys down a path. If the map is in this state, it will check
newly active paths, and if it finds a matching key, it will register
the key down all active paths.

Subject: [PATCH] multipathd: Added support to handle FPIN-Li events for
FC-NVMe
This patch adds the support to handle FPIN-Li for FC-NVMe.
On receiving the FPIN-Li events this patch moves the devices paths
which are affected due to link integrity to marginal path groups.
The paths which are set to marginal path group will be unset
on receiving the RSCN events

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] multipathd: Make sure to disable queueing if recovery has
failed.
If a multipath device has no_path_retry set to a number and has lost all
paths, gone into recovery mode, and timed out, it will disable
queue_if_no_paths. After that, if the device is reloaded by multipath
outside of multipathd, it will re-enable queuieng on the device. When
multipathd later calls set_no_path_retry() to update the queueing state,
it will not disable queue_if_no_paths, since the device is still in the
recovery state, so it believes no work needs to be done. The device will
remain in the recovery state, with retry_ticks at 0, and queueing
enabled, even though there are no usable paths.
To fix this, in set_no_path_retry(), if no_path_retry is set to a number
and the device is queueing but it is in recovery mode and out of
retries with no usable paths, manually disable queue_if_no_path.
