Subject: [PATCH] libmultipath: make set_int take a range for valid values
If a value outside of the valid range is passed to set_int, it caps the
value at appropriate limit, and issues a warning.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Benjamin Marzinski <bmarzins@redhat.com>
Date: Wed, 29 Sep 2021 12:56:04 -0500
Subject: [PATCH] libmultipath: improve checks for set_str
multipath always requires absolute pathnames, so make sure all file and
directory names start with a slash. Also check that the directories
exist. Finally, some strings, like the alias, will be used in paths.
These must not contain the slash character '/', since it is a forbidden
character in file/directory names. This patch adds seperate handlers for
these three cases. If a config line is invalid, these handlers retain
the existing config string, if any.

Subject: [PATCH] libmultipath: deprecate file and directory config options
Having multipath able to select pathnames for the files and directories
it needs causes unnecessary maintainer headaches. Mark these as
deprecated, but still support them for now.

Subject: [PATCH] libmultipath: split set_int to enable reuse
Split the code that does the actual value parsing out of set_int(), into
a helper function, do_set_int(), so that it can be used by other
handlers. These functions no longer set the config value at all, when
they have invalid input.

Subject: [PATCH] libmultipath: cleanup invalid config handling
Add error reporting to the remaining config handlers. If the value is
invalid, do not change the existing config option's value. Also print
an error whenever 0 is returned for an invalid value. When the handler
returns 1, config processing already fails with an error message.

Subject: [PATCH] libmultipath: don't return error on invalid values
do_set_int and set_uint return 1 for invalid values. This can cause
multipath to fail completely, while reading the config. The config
handlers should only return a non-zero value if there is an internal
error, not if there is just an invalid value.

Subject: [PATCH] multipathd: avoid unnecessary path read-only reloads
A mulitpath device can only be reloaded read/write when all paths are
read/write. Also, whenever a read-only device is rescanned, the scsi
subsystem will first unconditionally issue a uevent with DISK_RO=0
before checking the read-only status, and if it the device is still
read-only, issuing another uevent with DISK_RO=1. These uevents cause
pointless reloads when read-only paths are rescanned. To avoid this,
check to see if all paths are read/write before changing a multipath
device from read-only to read/write.
