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.

Subject: [PATCH] libmultipath: check udev_device_get_* return value to avoid
segfault
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.

Subject: [PATCH] libmultipath: avoid infinite loop with bad vpd page 83
identifier
If a device with a scsi name identifier has an unknown prefix,
parse_vpd_pg83() needs to advance to the next identifier, instead of
simply trying the same one again in an infinite loop.

Subject: [PATCH] RH: mpathconf: correctly handle spaces after option names
mpathconf was either accepting any number of spaces, including zero,

"mpathpersist -oCK <reservation_key> <device>" will return success if it

The -L command will fail, but it should give up sooner, and with a more

Subject: [PATCH] multipathd: don't access path if it was deleted
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.
