Subject: [PATCH] libmultipath: never allocate an alias that's already taken
If the bindings file is changed in a way that multipathd can't handle
(e.g. by swapping the aliases of two maps), multipathd must not try
to re-use an alias that is already used by another map. Creating
or renaming a map with such an alias will fail. We already avoid
this for some cases, but not for all. Fix it.

The name of the temp file is unlikely to be helpful for users,
and hard to predict in the unit test. Omit it.

Subject: [PATCH] libmultipath: keep bindings in memory
Rather than opening the bindings file every time we must retrieve
a binding, keep the contents in memory and write the file only
if additions have been made. This simplifies the code, and should speed up
alias lookups significantly. As a side effect, the aliases will be stored
sorted by alias, which changes the way aliases are allocated if there are
unused "holes" in the sequence of aliases. For example, if the bindings file
contains mpathb, mpathy, and mpatha, in this order, the next new alias used to
be mpathz and is now mpathc.
Another side effect is that multipathd will not automatically pick up changes
to the bindings file at runtime without a reconfigure operation. It is
questionable whether these on-the-fly changes were a good idea in the first
place, as inconsistent configurations may easily come to pass. It desired,
it would be feasible to implement automatic update of the bindings using the
existing inotify approach.
The new implementation of get_user_friendly_alias() is slightly different
than before. The logic is summarized in a comment in the code. Unit tests
will be provided that illustrate the changes.

Subject: [PATCH] libmultipath: adapt to new semantics of dm_get_uuid()
dm_get_uuid() will return 1 for non-existing maps. Thus we don't need
to call dm_map_present() any more in alias_already_taken(). This changes
our semantics: previously we'd avoid using an alias for which dm_get_uuid()
had failed. Now we treat failure in dm_get_uuid() as indication that the
map doesn't exist. This is not dangerous because dm_task_get_uuid() cannot
fail, and thus the modified dm_get_uuid() will fail if and only if
dm_map_present() would return false.
This makes the "failed alias" test mostly obsolete, as "failed" is now
treated as "unused".

Subject: [PATCH] libmultipath: sort aliases by length and strcmp
The current sort order of aliases is alphabetical, which is does not match
the actual order of aliases, where "mpathaa" > "mpathz". Change the ordering as
follows: first sort by string length, then alphabetically. This will make
sure that for aliases with the same prefix, alias order is correct ("mpathaaa"
will be sorted after "mpathzz", etc). Even for mixed prefixes, the alias
order will be correct for every individual prefix, even though aliases with
different prefixes may alternate in the file.

Subject: [PATCH] multipath-tools tests: add test for ordering of bindings
As the assignment of free aliases now relies on the bindings being
properly sorted, add some unit tests to make sure the sorting algorithm
works.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Martin Wilck <mwilck@suse.com>

Subject: [PATCH] multipathd: watch bindings file with inotify + timestamp
Since "libmultipath: keep bindings in memory", we don't re-read the
bindings file after every modification. Add a notification mechanism
that makes multipathd aware of changes to the bindings file. Because
multipathd itself will change the bindings file, it must compare
timestamps in order to avoid reading the file repeatedly.
Because select_alias() can be called from multiple thread contexts (uxlsnr,
uevent handler), we need to add locking for the bindings file. The
timestamp must also be protected by a lock, because it can't be read
or written atomically.
Note: The notification mechanism expects the bindings file to be
atomically replaced by rename(2). Changes must be made in a temporary file and
applied using rename(2), as in update_bindings_file(). The inotify
mechanism deliberately does not listen to close-after-write events
that would be generated by editing the bindings file directly. This
Note also: new bindings will only be read from add_map_with_path(),
i.e. either during reconfigure(), or when a new map is created during
runtime. Existing maps will not be renamed if the binding file changes,
unless the user runs "multipathd reconfigure". This is not a change
wrt the previous code, but it should be mentioned anyway.

Subject: [PATCH] multipath-tools tests: mock pthread_mutex_{lock,unlock}
If some test fails with a lock held, cmocka doesn't deal well with
pthread_cleanup_pop(). Such tests can cause deadlock with the locking
primitives in the alias code, because locks don't get properly unlocked. Just
mock the lock/unlock functions and generate an error if they weren't paired at
the end of the test.

Subject: [PATCH] multipath-tools Makefile: sanitize paths for configuration
files
Make the path to multipath.conf configurable, and use the same prefix
by default for multipath.conf and multipath/conf.d. For "usr-merged"
distributions with immutable /usr, we'll want to have the configuration
under a different prefix. This can be achieved by using e.g.
make prefix=/usr etc_prefix=""
Note that with prefix=/usr, before this patch the code would use
/usr/etc/multipath/conf.d, but /etc/multipath.conf. If this (rather
inconsistent) behavior is desired, use the following command line:
make prefix=/usr configfile=/etc/multipath.conf

Instead of hard-conding "/etc/multipath" as the path for the state
files "bindings", "prkeys", and "wwids", make this path configurable
via the "statedir" compile-time option. The default is currently still
/etc, it might change to /var/lib or similar in the future.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

Subject: [PATCH] libmultipath: avoid -Warray-bounds error in uatomic
operations
The use of uatomic_xchg() in alias.c causes a -Warray-bounds error
on distributions using gcc 12, such as Fedora 37. This is a similar
error to 2534c4f ("libmultipath: avoid -Warray-bounds error with gcc
12 and musl libc"). This happens only with liburcu 0.13 and earlier,
and only with certain gcc versions. See liburcu commit 835b9ab
("Fix: x86 and s390 uatomic: __hp() macro warning with gcc 11").
Enhance the fix for 2534c4f by a adding a workaround for uatomic_xchg(),
and introduce the macro URCU_VERSION (originally only used for multipathd)
globally.

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
