+Subject: [PATCH] libmutipath: don't close fd on dm_lib_release
+
+If dm_hold_control_open() isn't set, when dm_lib_release() is called, it
+will close the control fd. The control fd will get re-opened on the next
+dm_task_run() call, but if there is a dm_task_run() call already
+in progress in another thread, it can fail. Since many of the
+device-mapper callouts happen with the vecs lock held, this wasn't too
+noticeable, but there is code that calls dm_task_run() without the
+vecs lock held, notably the dmevent waiter code.
+
+Since, as Martin pointed out, dm_hold_control_open() hasn't always
+existed in libdevmapper, check if it's supported on compilation,
+and update the version requirements if so.

+Subject: [PATCH] libmultipath: allow force reload with no active paths
+
+If the partition information has changed on multipath devices (say,
+because it was updated on another node that has access to the same
+storage), users expect that running "multipathd reconfigure" will update
+that.  However, if the checkers for the multipath device are pending for
+too long when the the device is reconfigured, multipathd will give up
+waiting for them, and refuse to reload the device, since there are no
+active paths. This means that no kpartx update will be triggered.
+
+Multipath is fully capable of reloading a multipath device that has no
+active paths. This has been possible for years. If multipath is supposed
+to reload the device, it should do so, even if there are no active paths.
+
+Generally, when multipath is force reloaded, kpartx will be updated.
+However when a device is reloaded with no paths, the udev rules won't
+run kpartx.  But they also weren't running kpartx when the first valid
+path appeared, even though the dm activation rules get run in this case.
+This changes 11-dm-mpath.rules to run kpartx when a device goes from no
+usable paths to having usable paths.

-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] libmultipath: fix parser issue with comments in strings
+
+If a quoted string starts with '#' or '!', the parser will stop
+parsing the line, thinking that it's a comment.  It should only
+be checking for comments outside of quoted strings. Fixed this and
+added unit tests to verify it.

+Subject: [PATCH] libmultipath: invert regexes that start with exclamation
+ point
+
+The number of devices that multipath needs to blacklist keeps growing,
+and the udev rules already have
+
+KERNEL!="sd*|dasd*|nvme*", GOTO="end_mpath"
+
+so they only work correctly with these device types.  Instead of
+individually blacklisting every type of device that can't be
+multipathed, multipath's default blacklist should work like the udev
+rule, and blacklist all devices that aren't scsi, dasd, or nvme.
+Unfortunately, the c regex library doesn't support negative lookahead.
+Instead, multipath should treat "!" at the beginning of
+blacklist/exceptions regexes as inverse matching the rest of the regex.
+If users need to match a literal '!' as the first character of their
+regex, they can use "\!" instead. This allows multipath to change the
+default devnode blacklist regex to "!^(sd[a-z]|dasd[a-z]|nvme[0-9])".
+
+Extra tests have been added to the blacklist unit tests to verify the
+inverse matching code and the new default blacklist.

+Subject: [PATCH] libmultipath: make dm_get_map/status return codes symbolic
+
+dm_get_map() and dm_get_status() now use symbolic return codes. They
+also differentiate between failing to get information from device-mapper
+and not finding the requested device. These symboilc return codes are
+also used by update_multipath_* functions.

+Subject: [PATCH] multipathd: fix check_path errors with removed map
+
+If a multipath device is removed during, or immediately before the call
+to check_path(), multipathd can behave incorrectly. A missing multpath
+device will cause update_multipath_strings() to fail, setting
+pp->dmstate to PSTATE_UNDEF.  If the path is up, this state will cause
+reinstate_path() to be called, which will also fail.  This will trigger
+a reload, restoring the recently removed device.
+
+If update_multipath_strings() fails because there is no multipath
+device, check_path should just quit, since the remove dmevent and uevent
+are likely already queued up. Also, I don't see any reason to reload the
+multipath device if reinstate fails. This code was added by
+fac68d7a99ef17d496079538a5c6836acd7911ab, which clamined that reinstate
+could fail if the path was disabled.  Looking through the current kernel
+code, I can't see any reason why a reinstate would fail, where a reload
+would help. If the path was missing from the multipath device,
+update_multipath_strings() would already catch that, and quit
+check_path() early, which make more sense to me than reloading does.

+Subject: [PATCH] libmultipath: make dm_flush_maps only return 0 on success
+
+dm_flush_maps() returned both 0 and 1 on error, depending on which part
+of the function it was in, but the caller was always treating 0 as a
+success. Make dm_flush_maps() always return 1 on error and 0 on success.

+Since there can be problems with removing maps outside of multipathd,
+multipath should attempt to delegate this command to multipathd.
+However, multipathd doesn't attempt to suspend the device, in order
+to avoid potential hangs. If delegating to multipathd fails, multipath

+Subject: [PATCH] libmultipath: fix sysfs dev_loss_tmo parsing
+
+dev_loss_tmo is a u32 value. However the kernel sysfs code prints it as
+a signed integer. This means that if dev_loss_tmo is above INT_MAX, the
+sysfs value will be a negative number. Parsing this was causing
+sysfs_set_rport_tmo() to fail.

+Subject: [PATCH] kpartx: read devices with direct IO
+
+If kpartx is used on top of shared storage, and a device has its
+partition table changed on one machine, and then kpartx is run on
+another, it may not see the new data, because the cache still contains
+the old data, and there is nothing to tell the machine running kpartx to
+invalidate it. To solve this, kpartx should read the devices using
+direct io.
+
+One issue with how this code has been updated is that the original code
+for getblock() always read 1024 bytes. The new code reads a logical
+sector size chunk of the device, and returns a pointer to the 512 byte
+sector that the caller asked for, within that (possibly larger) chunk.
+This means that if the logical sector size is 512, then the code is now
+only reading 512 bytes.  Looking through the code for the various
+partition types, I can't see a case where more than 512 bytes is needed
+and getblock() is used.  If anyone has a reason why this code should be
+reading 1024 bytes at minmum, I can certainly change this.  But when I
+looked, I couldn't find a case where reading 512 bytes would cause a
+problem.

+Subject: [PATCH] libmultipath: fix checker detection for nvme devices
+
+In order to fix hwhandler autodetection, commit 8794a776 made
+detect_alua() differentiate between failures to detect whether alua was
+supported, and successfully detecting that it was not supported.
+However, this causes nvme devices to get the TUR checker assigned to
+them. This is because there is nothing in detect_alua() to make it only
+work on scsi devices, and select_checker wasn't updated to handle
+detect_alua() failing without setting pp->tpgs to TPGS_NONE.
+
+detect_alua() should automatically set pp->tpgs to TPGS_NONE and exit on
+non-scsi devices. Also, select_checker() should not assume that a
+devices is ALUA, simply because if failed to detect if alua was
+supported.
+
+Fixes: 8794a776 "libmultipath: fix ALUA autodetection when paths are

- historical-service-time PS
-
-The historical-service-time path selector prints out 2 path group status
-arguments. This is the only path selector that uses the group status
-arguments. All the others only have path status arguments.
-disassemble_status() was expecting the number of group status arguments
-to always be zero, causing it to fail at disassembling the status of
-devices that use historical-service-time path selector. Now multipath
-actually checks the number of group arguments, and skips them.

+Subject: [PATCH] libmultipath: count pending paths as active on loads
+
+When multipath loads a table, it signals to udev if there are no active
+paths.  Multipath wasn't counting pending paths as active.  This meant
+that if all the paths were pending, udev would treat the device as not
+ready, and not run kpartx on it.  Even if the pending paths later
+because active and were reinstated, the kernel would not send a new
+uevent, because from its point of view, they were always up.
+
+The alternative would be to continue to treat them as failed in the udev
+rules, but then also tell the kernel that they were down, so that it
+would trigger a uevent when they were reinstated. However, this could
+lead to newly created multipath devices failing IO, simply because the
+path checkers hadn't returned yet. Having udev assume that the the
+device is up, like the kernel does, seems like the safer option.

+
+delegate_to_multipathd() was returning success, even if the multipathd

+Subject: [PATCH] libmultipath: limit reading 0xc9 vpd page
+
+Only rdac arrays support 0xC9 vpd page inquiries. All other arrays will
+return a failure. Only do the rdac inquiry when detecting array
+capabilities if the array's path checker is explicitly set to rdac, or
+the path checker is not set, and the array reports that it supports vpd
+page 0xC9 in the Supported VPD Pages (0x00) vpd page.
+
+Multipath was doing the check if either the path checker was set to
+rdac, or no path checker was set.  This means that for almost all
+non-rdac arrays, multipath was issuing a bad inquiry. This was annoying
+users.

+
+Since fast_io_fail is part of the multipath struct, its symbolic values
+belong in structs.h. Also, make it an instance of a general enum, which
+will be used again in future patches, and change the set/print functions
+which use it to use the general enum instead.

+Subject: [PATCH] libmultipath: add eh_deadline multipath.conf parameter
+
+There are times a fc rport is never lost, meaning that fast_io_fail_tmo
+and dev_loss_tmo never trigger, but scsi commands still hang. This can
+cause problems in cases where users have string timing requirements, and
+the easiest way to solve these issues is to set eh_deadline. Since it's
+already possible to set fast_io_fail_tmo and dev_loss_tmo from
+multipath.conf, and have multipath take care of setting it correctly for
+the scsi devices in sysfs, it makes sense to allow users to set
+eh_deadline here as well.

-Subject: [PATCH] libmultipath: fix printing native nvme multipath topology.
-
-Since commit 2f05df4 ("libmultipath: use strbuf in print.c"), when
-multipath prints the topology of native nvme devices, instead of
-printing the multipath device information, it prints "w [G]:d s". This
-is because nvme_style() switched from calling snprintf(), which supports
-format specifiers, to append_strbuf_str(), which doesn't, while still
-keeping the same string, "%%w [%%G]:%%d %%s". Remove the extra percent
-signs, since they don't need to be escaped in append_strbuf_str().
-
-Fixes: 2f05df4 ("libmultipath: use strbuf in print.c")

+Subject: [PATCH] libmultipath: don't dlclose tur checker DSO
+
+The multipathd tur checker thread is designed to be able to finish at
+any time, even after the tur checker itself has been freed. The
+multipathd shutdown code makes sure all the checkers have been freed
+before freeing the checker_class and calling dlclose() to unload the
+DSO, but this doesn't guarantee that the checker threads have finished.
+If one hasn't, the DSO will get unloaded while the thread still running
+code from it, causing a segfault. Unfortunately, it's not possible to be
+sure that all tur checker threads have ended during shutdown, without
+making them joinable.
+
+However, since libmultipath will never be reinitialized after it has
+been uninitialzed, not dlclosing the tur checker DSO once a thread is
+started has minimal cost (keeping the DSO code around until the program
+exits, which usually happens right after freeing the checkers).

-Subject: [PATCH] multipathd: Don't keep starting TUR threads, if they always
- hang.
-
-If tur thead hangs, multipathd was simply creating a new thread, and
-assuming that the old thread would get cleaned up eventually. I have
-seen a case recently where there were 26000 multipathd threads on a
-system, all stuck trying to send TUR commands to path devices. The root
-cause of the issue was a scsi kernel issue, but it shows that the way
-multipathd currently deals with stuck threads could use some refinement.
-
-Now, when one tur thread hangs, multipathd will act as it did before.
-If a second one in a row hangs, multipathd will instead wait for it to
-complete before starting another thread. Once the thread completes, the
-count is reset.

+Subject: [PATCH] multipathd: avoid io_err_stat crash during shutdown
+
+The checker thread is reponsible for enqueueing paths for the
+io_err_stat thread to check. During shutdown, the io_err_stat thread is
+shut down and cleaned up before the checker thread.  There is no code
+to make sure that the checker thread isn't accessing the io_err_stat
+pathvec or its mutex while they are being freed, which can lead to
+memory corruption crashes.
+
+To solve this, get rid of the io_err_stat_pathvec structure, and
+statically define the mutex.  This means that the mutex is always valid
+to access, and the io_err_stat pathvec can only be accessed while
+holding it.  If the io_err_stat thread has already been cleaned up
+when the checker tries to access the pathvec, it will be NULL, and the
+checker will simply fail to enqueue the path.
+
+This change also fixes a bug in free_io_err_pathvec(), which previously
+only attempted to free the pathvec if it was not set, instead of when it
+was set.

+Subject: [PATCH] multipathd: avoid io_err_stat ABBA deadlock
+
+When the checker thread enqueues paths for the io_err_stat thread to
+check, it calls enqueue_io_err_stat_by_path() with the vecs lock held.
+start_io_err_stat_thread() is also called with the vecs lock held.
+These two functions both lock io_err_pathvec_lock. When the io_err_stat
+thread updates the paths in vecs->pathvec in poll_io_err_stat(), it has
+the io_err_pathvec_lock held, and then locks the vecs lock. This can
+cause an ABBA deadlock.
+
+To solve this, service_paths() no longer updates the paths in
+vecs->pathvec with the io_err_pathvec_lock held.  It does this by moving
+the io_err_stat_path from io_err_pathvec to a local vector when it needs
+to update the path. After releasing the io_err_pathvec_lock, it goes
+through this temporary vector, updates the paths with the vecs lock
+held, and then frees everything.
+
+This change fixes a bug in service_paths() where elements were being
+deleted from io_err_pathvec, without the index being decremented,
+causing the loop to skip elements. Also, service_paths() could be
+cancelled while holding the io_err_pathvec_lock, so it should have a
+cleanup handler.

+Subject: [PATCH] multipathd: cleanup logging for marginal paths
+
+io_err_stat logged at level 2 whenever it enqueued a path to check,
+which could happen multiple times while a path was marginal.  On the
+other hand if marginal_pathgroups wasn't set, multipathd didn't log when
+paths were set to marginal. Now io_err_stat only logs at level 2 when
+something unexpected happens, but multipathd will always log when a
+path switches its marginal state.
+
+This patch also fixes an issue where paths in the delayed state could
+get set to the pending state if they could not be checked in time.
+Aside from going against the idea the paths should not be set to pending
+if they already have a valid state, this caused multipathd to log a
+message whenever the path state switched to from delayed to pending and
+then back.

+Subject: [PATCH] libmpathpersist: fix thread safety of default functions
+
+commit a839e39e ("libmpathpersist: factor out initialization and
+teardown") made mpath_presistent_reserve_{in,out} use share variables
+for curmp and pathvec.  There are users of this library that call these
+functions in a multi-threaded process, and this change causes their
+application to crash. config and udev are also shared variables, but
+libmpathpersist doesn't write to the config in
+mpath_presistent_reserve_{in,out}, and looking into the libudev code, I
+don't see any place where libmpathpersist uses the udev object in a way
+that isn't thread-safe.
+
+This patch makes mpath_presistent_reserve_{in,out} go back to using
+local variables for curmp and pathvec, so that multiple threads won't
+be operating on these variables at the same time.

+Subject: [PATCH] kpartx: free loop device after listing partitions
+
+If "kpartx -l" is run on a file that doesn't already have a loop device
+associated with it, it will create a loop device to run the command.
+Starting with da59d15c6 ("Fix loopback file with kpartx -av"), it will
+not free the loop device when exitting. This is because it checks if the
+the file it stat()ed is a regular file, before freeing the loop device.
+However, after da59d15c6, stat() is rerun on the loop device itself, so
+the check fails.  There is no need to check this, if loopcreated is
+true, then the file will be a kpartx created loop device, and should be
+freed.
+
+Also, keep kpartx from printing that the loop device has been removed
+at normal verbosity.
+
+Fixes: da59d15c6 ("Fix loopback file with kpartx -av")

+Subject: [PATCH] libmultipath: select_action(): don't drop map if alias
+ clashes
+
+If for a given map, if we find that the requested alias is already
+used by a map with different WWID, while the map's own WWID is
+not used yet, give up the alias and use the WWID instead. This
+is safer than trying to destroy the existing map, which is likely
+to fail.
+
+This allows us to make use const for the "curmp" parameter.

+Subject: [PATCH] libmultipath: check if user_friendly_name is in use
+
+If there are multipath devices that have user_friendly_names but do not
+have their bindings in the bindings_file, get_user_friendly_alias() can
+currently give out those names again. This can result in an incorrect
+entry in the bindings file, and a device that gets created with a WWID
+alias instead of a user_friendly_name. This situation can happen after
+the pivot root, if a multipath device is created in the initramfs.  If
+this device doesn't have a binding in the regular filesystem
+bindings_file and a new multipath device is created before it can add
+its binding, the new device can steal that user_friendly_name during
+multipathd's initial configure.
+
+To solve this, get_user_friendly_alias() now calls lookup_binding() with
+a new paramter, telling it to check if the id it found is already in use
+by a diffent device. If so, lookup_binding() will continue to check open
+ids, until it finds one that it not currently in use by a dm device.

+
+The udev_device_get_* function may return NULL, and it will be
+deregerenced in str* and sscanf func. We check the return value
+to avoid segfault. Fix all.

+Subject: [PATCH] multipathd: add recheck_wwid option to verify the path wwid
+
+There are cases where the wwid of a path changes due to LUN remapping
+without triggering uevent for the changed path. Multipathd has no method
+for trying to catch these cases, and corruption has resulted because of
+it.
+
+In order to have a better chance at catching these cases, multipath now
+has a recheck_wwid option. If this is set to "yes", when a failed path
+has become active again, multipathd will recheck its wwid. If multipathd
+notices that a path's wwid has changed, it will remove and re-add the
+path, just like the existing wwid checking code for change events does.
+In cases where the no uevent occurs, both the udev database entry and
+sysfs will have the old wwid, so the only way to get a current wwid is
+to ask the device directly. Currently multipath only has code to
+directly get the wwid for scsi devices, so this option only effects scsi
+devices, and they must be configured to be able to use the uid_fallback
+methods. To make sure both the sysfs and udev database values are
+updated, multipathd triggers a both a rescan of the device and a udev
+add event.

-
-The multpath-tools do not support the io-affinity path selector.  We
-always add a repeat count as the path argument. The io-affinity selector
-doesn't take one. Instead it takes a bit map of CPUs that a path can
-run on. This isn't something that lends itself to the kind of
-auto-assembling that multipathd does. But even if we did want to
-try to support this path-selector, until we do, we shouldn't be listing
-it in the multipath.conf documentation.

+
+ev_remove_path() could fail and still delete the path. This could cause
+problems for handle_path_wwid_change(), which expected that a failure
+meant that the path still existed. ev_remove_path now returns a
+different error code for failure to reload the multipath device, so that
+it can be differentiated from cases where the path was no removed.
