Subject: [PATCH] multipathd: fix missing persistent reseravtion for active
path
There are two paths(sucu as sda and adb) for one LUN. The two
paths log in, but before the two uevents have been processed
(for example there are many uevent), users use multipathd add
path /dev/sda to cause mpatha and use mpathpersist -o -I to
register prkey for mpatha. The add map uevent is after add path
uevent, the the uevent(add sdb) will delay and missing persistent
reseravtion check.
Here, we add persistent reseravtion check in update_map() which
is called ev_add_map().

Subject: [PATCH] multipathd.socket: add missing conditions from service unit
This aligns 'multipathd' socket and service units, by adding the
start conditions that are set on the service but not on the socket.
It should help avoiding situations where the socket unit ends up
marked as failed after hitting its retry-limit.

Subject: [PATCH] Revert "multipath-tools: make EMC/Invista config work with
alua and multibus"
This reverts commit 309ff281aaa07e862540d3d645a8263f3e9baaed.
Mail from <Wayne.Berthiaume@dell.com>, 20210930:
"OPM is no longer supported in the Dell VPLEX product. If we at Dell had
wished to change the default device stanzas for any of our products they
would have been done when the product and/or feature is released.
Please remove this patch as well. It is not needed."

Subject: [PATCH] multipathd: don't fail to remove path once the map is removed
In ev_remove_path(), if update_mpp_paths() fails, we delete the entire
map. However, since update_mpp_paths() happens before we call
set_path_removed(), pp->initialized isn't set to INIT_REMOVED, so
remove_map_and_stop_waiter() doesn't remove the path when in removes the
map. But with the map removed, there's nothing to keep us from removing
the path.
Call set_path_removed() before update_mpp_paths() to avoid the odd case
of ev_remove_path() removing the map but not the path.

Mail from "berthiaume, wayne" <Wayne.Berthiaume@dell.com>, 210930:
"As a representative of Dell I request this patch be withdrawn. If we had
wanted the default stanza changed we would have already implemented it.
Also for your information we only advertise the entire enterprise storage
product line (DMX, VMAX, VMAX AFA, PowerMax) as SYMMETRIX in the VPD page.
The ALUA capability is only used for mobility devices in an SRDF/Metro
configuration and the current device stanza still works well in all of our
testing."

Subject: [PATCH] multipathd: fix ev_remove_path return code handling
When ev_remove_path() returned success, callers assumed that the path
(and possibly the map) had been removed. When ev_remove_path() returned
failure, callers assumed that the path had not been removed. However,
the path could be removed on both success or failure. This could cause
callers to dereference the path after it was removed.
To deal with this, make ev_remove_path() return a different symbolic
value for each outcome, and make the callers react appropriately for
the different values. Found by coverity.

Subject: [PATCH] multipathd: don't rescan_path on wwid change in
uev_update_path
If get_uid() is returning a different wwid in uev_update_path(), then
the uid_attribute must have already gotten updated, which was the
purpose behind calling rescan_path() in the first place.

From: Benjamin Marzinski <bmarzins@redhat.com>
Date: Fri, 9 Jul 2021 14:30:10 -0500
Subject: [PATCH] RH: mpathconf: correctly handle spaces after option names
mpathconf was either accepting any number of spaces, including zero,
after option names, or it was only accepting one space. It should
accept one or more spaces. Also, fix enable_foreign handling. It was
still working like it did in RHEL8, where the default was to enable
all foreign devices.

Subject: [PATCH] mpathpersist: fail commands when no usable paths exist
"mpathpersist -oCK <reservation_key> <device>" will return success if it
is run on devices with no usable paths, but nothing is actually done.
The -L command will fail, but it should give up sooner, and with a more
helpful error message.

Subject: [PATCH] libmultipath: deal with dynamic PTHREAD_STACK_MIN
Starting in glibc-2.34 (commit 5d98a7da), PTHREAD_STACK_MIN is defined
as sysconf(_SC_THREAD_STACK_MIN) if _GNU_SOURCE is defined. sysconf()
returns a long and can, at least in theory, return -1. This change
causes compilation to fail in setup_thread_attr() due to a comparision
with different signedness, since stacksize is a size_t.

Subject: [PATCH] RH: make parse_vpd_pg83 match scsi_id output
Red Hat sets ID_SERIAL based on the result of scsi_id, instead of using
the result of sg_inq and 55-scsi-sg3_id.rules. Make parse_vpd_pg83 match
that.

Subject: [PATCH] multipathd: cli_handlers: cleanup setting reply length
Create a macro for setting the reply length for string literals
correctly, and use it where necessary.
In cli_del_path(), don't change the function's return code
if just the buffer allocation for the reply failed.

Subject: [PATCH] libmultipath: add section name to invalid keyword output
If users forget the closing brace for a section in multipath.conf,
multipath has no way to detect that. When it sees the keyword at the
start of the next section, it will complain that there is an invalid
keyword, because that keyword doesn't belong in previous section (which
was never ended with a closing brace). This can confuse users. To make
this easier to understand, when multipath prints an invalid keyword
message, it now also prints the current section name, which can give
users a hint that they didn't end the previous section.

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.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001

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.
