NVM Express 1.2.1 section 7.9, NVMe Qualified Names, specifies that the
UUID format of NQN uses a UUID based on RFC 4122.
RFC 4122 specifies that the UUID is encoded in big-endian byte order.
Switch the NVMe over Fabrics host ID field from little-endian UUID to
big-endian UUID to match the specification.

Per NVMe-over-Fabrics 1.0 spec, sqsize is represented as
a 0-based value.
Also per spec, the RDMA binding values shall be set
to sqsize, which makes hsqsize 0-based values.
Thus, the sqsize during NVMf connect() is now:
[root@fedora23-fabrics-host1 for-48]# dmesg
[ 318.720645] nvme_fabrics: nvmf_connect_admin_queue(): sqsize for
admin queue: 31
[ 318.720884] nvme nvme0: creating 16 I/O queues.
[ 318.810114] nvme_fabrics: nvmf_connect_io_queue(): sqsize for i/o
queue: 127
Finally, current interpretation implies hrqsize is 1's based
so set it appropriately.

Upon admin queue connect(), the rdma qp was being
set based on NVMF_AQ_DEPTH. However, the fabrics layer was
using the sqsize field value set for I/O queues for the admin
queue, which threw the nvme layer and rdma layer off-whack:
root@fedora23-fabrics-host1 nvmf]# dmesg
[ 3507.798642] nvme_fabrics: nvmf_connect_admin_queue():admin sqsize
being sent is: 128
[ 3507.798858] nvme nvme0: creating 16 I/O queues.
[ 3507.896407] nvme nvme0: new ctrl: NQN "nullside-nqn", addr
192.168.1.3:4420
Thus, to have a different admin queue value, we use
NVMF_AQ_DEPTH for connect() and RDMA private data
as the minimum depth specified in the NVMe-over-Fabrics 1.0 spec
(and in that RDMA private data we treat hrqsize as 1's-based
value, per current understanding of the fabrics spec).

small reads
Under extreme conditions this might cause data corruptions. By doing that
we we repost the buffer and then post this buffer for the device to send.
If we happen to use shared receive queues the device might write to the
buffer before it sends it (there is no ordering between send and recv
queues). Without SRQs we probably won't get that if the host doesn't
mis-behave and send more than we allowed it, but relying on that is not
really a good idea.

When configuring a device attached listener, we may
see device removal events. In this case we return a
non-zero return code from the cm event handler which
implicitly destroys the cm_id. It is possible that in
the future the user will remove this listener and by
that trigger a second call to rdma_destroy_id on an
already destroyed cm_id -> BUG.
In addition, when a queue bound (active session) cm_id
generates a DEVICE_REMOVAL event we must guarantee all
resources are cleaned up by the time we return from the
event handler.
Introduce nvmet_rdma_device_removal which addresses
(or at least attempts to) both scenarios.

Relying on ctrl state in nvme_rdma_shutdown_ctrl is wrong because
it will never be NVME_CTRL_LIVE (delete_ctrl or reset_ctrl invoked it).
Instead, check that the admin queue is connected. Note that it is safe
because we can never see a copmeting thread trying to destroy the admin
queue (reset or delete controller).

If we wait until we free the controller (free_ctrl) we might
lose our rdma device without any notification while we still
have open resources (tags mrs and dma mappings).
Instead, destroy the tags with their rdma resources once we
delete the device and not when freeing it.
Note that we don't do that in nvme_rdma_shutdown_ctrl because
controller reset uses it as well and we want to give active I/O
a chance to complete successfully.

Device removal sequence may have crashed because the
controller (and admin queue space) was freed before
we destroyed the admin queue resources. Thus we
want to destroy the admin queue and only then queue
controller deletion and wait for it to complete.
More specifically we:
1. own the controller deletion (make sure we are not
competing with another deletion).
2. get rid of inflight reconnects if exists (which
also destroy and create queues).
3. destroy the queue.
4. safely queue controller deletion (and wait for it
to complete).

On an ordered target shutdown, the target can send a AEN on a namespace
removal, this will trigger the host to queue ns-list query. The shutdown
will trigger error recovery which will attepmt periodic reconnect.
We can hit a race where the ns rescanning fails (error recovery kicked
in and we're not connected) causing removing all the namespaces and when
we reconnect we won't see any namespaces for this controller.
So, queue a namespace rescan after we successfully reconnected to the target.

On a system with sparse node ids, eg. a powerpc system with 4 nodes
numbered like so:
node 0: [mem 0x0000000000000000-0x00000007ffffffff]
node 1: [mem 0x0000000800000000-0x0000000fffffffff]
node 16: [mem 0x0000001000000000-0x00000017ffffffff]
node 17: [mem 0x0000001800000000-0x0000001fffffffff]
The code in rand_initialize() will allocate 4 pointers for the pool
array, and initialise them correctly.
However when go to use the pool, in eg. extract_crng(), we use the
numa_node_id() to index into the array. For the higher numbered node ids
this leads to random memory corruption, depending on what was kmalloc'ed
adjacent to the pool array.
Fix it by using nr_node_ids to size the pool array.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull userns vfs updates from Eric Biederman:
"This tree contains some very long awaited work on generalizing the
user namespace support for mounting filesystems to include filesystems
with a backing store. The real world target is fuse but the goal is
to update the vfs to allow any filesystem to be supported. This
patchset is based on a lot of code review and testing to approach that
goal.
While looking at what is needed to support the fuse filesystem it
became clear that there were things like xattrs for security modules
that needed special treatment. That the resolution of those concerns
would not be fuse specific. That sorting out these general issues
made most sense at the generic level, where the right people could be
drawn into the conversation, and the issues could be solved for
everyone.
At a high level what this patchset does a couple of simple things:
- Add a user namespace owner (s_user_ns) to struct super_block.
- Teach the vfs to handle filesystem uids and gids not mapping into
to kuids and kgids and being reported as INVALID_UID and
INVALID_GID in vfs data structures.
By assigning a user namespace owner filesystems that are mounted with
only user namespace privilege can be detected. This allows security
modules and the like to know which mounts may not be trusted. This
also allows the set of uids and gids that are communicated to the
filesystem to be capped at the set of kuids and kgids that are in the
owning user namespace of the filesystem.
One of the crazier corner casees this handles is the case of inodes
whose i_uid or i_gid are not mapped into the vfs. Most of the code
simply doesn't care but it is easy to confuse the inode writeback path
so no operation that could cause an inode write-back is permitted for
such inodes (aka only reads are allowed).
This set of changes starts out by cleaning up the code paths involved
in user namespace permirted mounts. Then when things are clean enough
adds code that cleanly sets s_user_ns. Then additional restrictions
are added that are possible now that the filesystem superblock
contains owner information.
These changes should not affect anyone in practice, but there are some
parts of these restrictions that are changes in behavior.
- Andy's restriction on suid executables that does not honor the
suid bit when the path is from another mount namespace (think
/proc/[pid]/fd/) or when the filesystem was mounted by a less
privileged user.
- The replacement of the user namespace implicit setting of MNT_NODEV
with implicitly setting SB_I_NODEV on the filesystem superblock
instead.
Using SB_I_NODEV is a stronger form that happens to make this state
user invisible. The user visibility can be managed but it caused
problems when it was introduced from applications reasonably
expecting mount flags to be what they were set to.
There is a little bit of work remaining before it is safe to support
mounting filesystems with backing store in user namespaces, beyond
what is in this set of changes.
- Verifying the mounter has permission to read/write the block device
during mount.
- Teaching the integrity modules IMA and EVM to handle filesystems
mounted with only user namespace root and to reduce trust in their
security xattrs accordingly.
- Capturing the mounters credentials and using that for permission
checks in d_automount and the like. (Given that overlayfs already
does this, and we need the work in d_automount it make sense to
generalize this case).
Furthermore there are a few changes that are on the wishlist:
- Get all filesystems supporting posix acls using the generic posix
acls so that posix_acl_fix_xattr_from_user and
posix_acl_fix_xattr_to_user may be removed. [Maintainability]
- Reducing the permission checks in places such as remount to allow
the superblock owner to perform them.
- Allowing the superblock owner to chown files with unmapped uids and
gids to something that is mapped so the files may be treated
normally.
I am not considering even obvious relaxations of permission checks
until it is clear there are no more corner cases that need to be
locked down and handled generically.
Many thanks to Seth Forshee who kept this code alive, and putting up
with me rewriting substantial portions of what he did to handle more
corner cases, and for his diligent testing and reviewing of my
changes"

The workqueue "workq" provides support for sd/mmc async request, which
makes next request do dma_map_sg() while previous request transferring
data.
The workqueue has a single workitem(&host->work) and hence doesn't require
ordering. Also, it is not being used on a memory reclaim path. Hence,
the singlethreaded workqueue has been replaced with the use of system_wq.
System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.
Work item has been flushed in rtsx_pci_sdmmc_drv_remove() to ensure that
there are no pending tasks while disconnecting the driver.

The rtsx_pci driver is using a fixed 3s timeout for R1B responses, which
in some cases isn't suffient. For example, erase/discard requests may
require longer timeouts.
Instead of always using a fixed timeout, let's use the per request
calculated busy timeout from the mmc core.

Move the system PM callbacks within #ifdef CONFIG_PM_SLEEP as to avoid

Within this context it also makes sense to move the declaration of the

SET_SYSTEM_SLEEP_PM_OPS deals with this. This further simplifies the code.

Pull libnvdimm updates from Dan Williams:
- Replace pcommit with ADR / directed-flushing.
The pcommit instruction, which has not shipped on any product, is
deprecated. Instead, the requirement is that platforms implement
either ADR, or provide one or more flush addresses per nvdimm.
ADR (Asynchronous DRAM Refresh) flushes data in posted write buffers
to the memory controller on a power-fail event.
Flush addresses are defined in ACPI 6.x as an NVDIMM Firmware
Interface Table (NFIT) sub-structure: "Flush Hint Address Structure".
A flush hint is an mmio address that when written and fenced assures
that all previous posted writes targeting a given dimm have been
flushed to media.
- On-demand ARS (address range scrub).
Linux uses the results of the ACPI ARS commands to track bad blocks
in pmem devices. When latent errors are detected we re-scrub the
media to refresh the bad block list, userspace can also request a
re-scrub at any time.

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v4.8 kernel cycle.
Nothing stands out as especially exiting: new drivers, new subdrivers,
lots of cleanups and incremental features.
Business as usual.
New drivers:
- New driver for Oxnas pin control and GPIO. This ARM-based chipset
is used in a few storage (NAS) type devices.
- New driver for the MAX77620/MAX20024 pin controller portions.
- New driver for the Intel Merrifield pin controller.
New subdrivers:
- New subdriver for the Qualcomm MDM9615
- New subdriver for the STM32F746 MCU
- New subdriver for the Broadcom NSP SoC.
Cleanups:
- Demodularization of bool compiled-in drivers.
Apart from this there is just regular incremental improvements to a
lot of drivers, especially Uniphier and PFC"
