10fd71780f SCSI misc on 20190919 
This is mostly update of the usual drivers: qla2xxx, ufs, smartpqi,
 lpfc, hisi_sas, qedf, mpt3sas; plus a whole load of minor updates.
 The only core change this time around is the addition of request
 batching for virtio.  Since batching requires an additional flag to
 use, it should be invisible to the rest of the drivers.

3e414b5bd2 - crypto and DM crypt advances that allow the crypto API to reclaim 
implementation details that do not belong in DM crypt.  The wrapper
   template for ESSIV generation that was factored out will also be used
   by fscrypt in the future.
 
 - Add root hash pkcs#7 signature verification to the DM verity target.
 
 - Add a new "clone" DM target that allows for efficient remote
   replication of a device.
 
 - Enhance DM bufio's cache to be tailored to each client based on use.
   Clients that make heavy use of the cache get more of it, and those
   that use less have reduced cache usage.
 
 - Add a new DM_GET_TARGET_VERSION ioctl to allow userspace to query the
   version number of a DM target (even if the associated module isn't yet
   loaded).
 
 - Fix invalid memory access in DM zoned target.
 
 - Fix the max_discard_sectors limit advertised by the DM raid target; it
   was mistakenly storing the limit in bytes rather than sectors.
 
 - Small optimizations and cleanups in DM writecache target.
 
 - Various fixes and cleanups in DM core, DM raid1 and space map portion
   of DM persistent data library.

Merge tag 'drm-next-2019-09-18' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
 "This is the main pull request for 5.4-rc1 merge window. I don't think
  there is anything outstanding so next week should just be fixes, but
  we'll see if I missed anything. I landed some fixes earlier in the
  week but got delayed writing summary and sending it out, due to a mix
  of sick kid and jetlag!

  There are some fixes pending, but I'd rather get the main merge out of
  the way instead of delaying it longer.

  It's also pretty large in commit count and new amd header file size.
  The largest thing is four new amdgpu products (navi12/14, arcturus and
  renoir APU support).

  Otherwise it's pretty much lots of work across the board, i915 has
  started landing tigerlake support, lots of icelake fixes and lots of
  locking reworking for future gpu support, lots of header file rework
  (drmP.h is nearly gone), some old legacy hacks (DRM_WAIT_ON) have been
  put into the places they are needed.

Pull input updates from Dmitry Torokhov:

 - input core allows hardware drivers to specify a [more precise]
   timestamp (normally taken in top half) to better track velocity of
   contacts

 - input_dev instances now support "polling" mode so that drivers could
   use the same object for polled and interrupt-driven operation. The
   plan is to convert existing drivers and retire input_polled_dev API

 - a new driver for the FlySky FS-iA6B RC receiver

 - a refresh of BU21013 touchpad driver

 - w90x900 keyboard and touchpad drivers are removed as the platform is
   gone

 - assorted fixes

Merge tag 'for-5.4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs updates from David Sterba:
 "This continues with work on code refactoring, sanity checks and space
  handling. There are some less user visible changes, nothing that would
  particularly stand out.

  User visible changes:
   - tree checker, more sanity checks of:
       - ROOT_ITEM (key, size, generation, level, alignment, flags)
       - EXTENT_ITEM and METADATA_ITEM checks (key, size, offset,
         alignment, refs)
       - tree block reference items
       - EXTENT_DATA_REF (key, hash, offset)

   - deprecate flag BTRFS_SUBVOL_CREATE_ASYNC for subvolume creation
     ioctl, scheduled removal in 5.7

   - delete stale and unused UAPI definitions
     BTRFS_DEV_REPLACE_ITEM_STATE_*

   - improved export of debugging information available via existing
     sysfs directory structure

   - try harder to delete relations between qgroups and allow to delete
     orphan entries

   - remove unreliable space checks before relocation starts

  Core:
   - space handling:
       - improved ticket reservations and other high level logic in
         order to remove special cases
       - factor flushing infrastructure and use it for different
         contexts, allows to remove some special case handling
       - reduce metadata reservation when only updating inodes
       - reduce global block reserve minimum size (affects small
         filesystems)
       - improved overcommit logic wrt global block reserve

   - tests:
       - fix memory leaks in extent IO tree
       - catch all TRIM range

  Fixes:
   - fix ENOSPC errors, leading to transaction aborts, when cloning
     extents

   - several fixes for inode number cache (mount option inode_cache)

   - fix potential soft lockups during send when traversing large trees

   - fix unaligned access to space cache pages with SLUB debug on
     (PowerPC)

  Other:
   - refactoring public/private functions, moving to new or more
     appropriate files

   - defines converted to enums

   - error handling improvements

   - more assertions and comments

   - old code deletion"

f60c55a94e fs-verity for 5.4 
Please consider pulling fs-verity for 5.4.
 
 fs-verity is a filesystem feature that provides Merkle tree based
 hashing (similar to dm-verity) for individual readonly files, mainly for
 the purpose of efficient authenticity verification.
 
 This pull request includes:
 
 (a) The fs/verity/ support layer and documentation.
 
 (b) fs-verity support for ext4 and f2fs.
 
 Compared to the original fs-verity patchset from last year, the UAPI to
 enable fs-verity on a file has been greatly simplified.  Lots of other
 things were cleaned up too.
 
 fs-verity is planned to be used by two different projects on Android;
 most of the userspace code is in place already.  Another userspace tool
 ("fsverity-utils"), and xfstests, are also available.  e2fsprogs and
 f2fs-tools already have fs-verity support.  Other people have shown
 interest in using fs-verity too.
 
 I've tested this on ext4 and f2fs with xfstests, both the existing tests
 and the new fs-verity tests.  This has also been in linux-next since
 July 30 with no reported issues except a couple minor ones I found
 myself and folded in fixes for.
 
 Ted and I will be co-maintaining fs-verity.

734d1ed83e fscrypt update for 5.4 
This is a large update to fs/crypto/ which includes:
 
 - Add ioctls that add/remove encryption keys to/from a filesystem-level
   keyring.  These fix user-reported issues where e.g. an encrypted home
   directory can break NetworkManager, sshd, Docker, etc. because they
   don't get access to the needed keyring.  These ioctls also provide a
   way to lock encrypted directories that doesn't use the vm.drop_caches
   sysctl, so is faster, more reliable, and doesn't always need root.
 
 - Add a new encryption policy version ("v2") which switches to a more
   standard, secure, and flexible key derivation function, and starts
   verifying that the correct key was supplied before using it.  The key
   derivation improvement is needed for its own sake as well as for
   ongoing feature work for which the current way is too inflexible.
 
 Work is in progress to update both Android and the 'fscrypt' userspace
 tool to use both these features.  (Working patches are available and
 just need to be reviewed+merged.)  Chrome OS will likely use them too.
 
 This has also been tested on ext4, f2fs, and ubifs with xfstests -- both
 the existing encryption tests, and the new tests for this.  This has
 also been in linux-next since Aug 16 with no reported issues.  I'm also
 using an fscrypt v2-encrypted home directory on my personal desktop.

e444d51b14 TTY/Serial driver changes for 5.4-rc1 
Even in this age, people are still making new serial port silicon,
 why...
 
 Anyway, here's the TTY and Serial driver update for 5.4-rc1.  Lots of
 changes in here for a number of embedded serial port devices that are
 being worked on because people really like to see those console logs...
 
 Other than that, nothing major here, no core tty changes that anyone
 should care about.
 
 All of these have been in linux-next for a while with no reported
 issues.

c6b48dad92 USB changes for 5.4-rc1 
Here is the big set of USB patches for 5.4-rc1.
 
 Two major chunks of code are moving out of the tree and into the staging
 directory, uwb and wusb (wireless USB support), because there are no
 devices that actually use this protocol anymore, and what we have today
 probably doesn't work at all given that the maintainers left many many
 years ago.  So move it to staging where it will be removed in a few
 releases if no one screams.
 
 Other than that, lots of little things.  The usual gadget and xhci and
 usb serial driver updates, along with a bunch of sysfs file cleanups due
 to the driver core changes to support that.  Nothing really major, just
 constant forward progress.
 
 All of these have been in linux-next for a while with no reported
 issues.

6ab8ad3160 sound updates for 5.4 
As shown in diffstat and logs, it was again a busy development
 cycle at this time, too.  The most significant changes are still
 on-going refactoring / modernization works for ASoC core and
 drivers, but there are lots of other changes as well.  Here we go,
 some highlights below:
 
 ASoC:
 - Quite lots of cleanup / refactoring of ASoC core and APIs;
   most of them are systematic, but also including cleanups and
   modernization
 
 - A bulk of updates for some ASoC platforms, Freescale, sunxi and
   Intel SST/SOF
 
 - Initial support for Sound Open Firmware on i.MX8
 
 - Removal of deprecated w90x900 and nuc900 drivers
 
 - New support for Cirrus Logic CS47L15 and CS47L92, Freescale i.MX
   7ULP and 8MQ, Meson G12A and NXP UDA1334
 
 USB-audio:
 - More validations of descriptor units for hardening against bugs
   reported by fuzzers
 
 - PCM device assignment workaround for a past call-order change
 
 - Scarlett Gen2 mixer interface, a few more more quirks
 
 HD-audio:
 - Support for audio component with AMD/ATI and Nvidia HDMI codecs
 
 - Clean up HD-audio core and remove indirect access ops for Intel SOF
 
 - DMIC detection at probe; it would make systems automatically falling
   back to SST/SOF driver on devices that need DMIC handling.
   Needs a new Kconfig to set, and beware that it's still new and a bit
   experimental
 
 FireWire:
 - Lots of code refactoring and cleanups

 "Although there isn't tonnes of code in terms of line count, there are
  a fair few headline features which I've noted both in the tag and also
  in the merge commits when I pulled everything together.

  time around, which feels like a big jump from the usual small group of
  core arm64 arch developers. Hopefully they all enjoyed it so much that
  they'll continue to contribute, but we'll see.

  It's probably worth highlighting that we've pulled in a branch from
  the risc-v folks which moves our CPU topology code out to where it can
  be shared with others.

9f2f13f4ff ethtool: implement Energy Detect Powerdown support via phy-tunable 
The `phy_tunable_id` has been named `ETHTOOL_PHY_EDPD` since it looks like
this feature is common across other PHYs (like EEE), and defining
`ETHTOOL_PHY_ENERGY_DETECT_POWER_DOWN` seems too long.

The way EDPD works, is that the RX block is put to a lower power mode,
except for link-pulse detection circuits. The TX block is also put to low
power mode, but the PHY wakes-up periodically to send link pulses, to avoid
lock-ups in case the other side is also in EDPD mode.

Currently, there are 2 PHY drivers that look like they could use this new
PHY tunable feature: the `adin` && `micrel` PHYs.

The ADIN's datasheet mentions that TX pulses are at intervals of 1 second
default each, and they can be disabled. For the Micrel KSZ9031 PHY, the
datasheet does not mention whether they can be disabled, but mentions that
they can modified.

The way this change is structured, is similar to the PHY tunable downshift
control:
* a `ETHTOOL_PHY_EDPD_DFLT_TX_MSECS` value is exposed to cover a default
  TX interval; some PHYs could specify a certain value that makes sense
* `ETHTOOL_PHY_EDPD_NO_TX` would disable TX when EDPD is enabled
* `ETHTOOL_PHY_EDPD_DISABLE` will disable EDPD

As noted by the `ETHTOOL_PHY_EDPD_DFLT_TX_MSECS` the interval unit is 1
millisecond, which should cover a reasonable range of intervals:
 - from 1 millisecond, which does not sound like much of a power-saver
 - to ~65 seconds which is quite a lot to wait for a link to come up when
   plugging a cable

9c66d15646 taprio: Add support for hardware offloading 
This allows taprio to offload the schedule enforcement to capable
network cards, resulting in more precise windows and less CPU usage.

The gate mask acts on traffic classes (groups of queues of same
priority), as specified in IEEE 802.1Q-2018, and following the existing
taprio and mqprio semantics.
It is up to the driver to perform conversion between tc and individual
netdev queues if for some reason it needs to make that distinction.

Full offload is requested from the network interface by specifying
"flags 2" in the tc qdisc creation command, which in turn corresponds to
the TCA_TAPRIO_ATTR_FLAG_FULL_OFFLOAD bit.

The important detail here is the clockid which is implicitly /dev/ptpN
for full offload, and hence not configurable.

A reference counting API is added to support the use case where Ethernet
drivers need to keep the taprio offload structure locally (i.e. they are
a multi-port switch driver, and configuring a port depends on the
settings of other ports as well). The refcount_t variable is kept in a
private structure (__tc_taprio_qopt_offload) and not exposed to drivers.

In the future, the private structure might also be expanded with a
backpointer to taprio_sched *q, to implement the notification system
described in the patch (of when admin became oper, or an error occurred,
etc, so the offload can be monitored with 'tc qdisc show').

Pull pidfd/waitid updates from Christian Brauner:
 "This contains two features and various tests.

  First, it adds support for waiting on process through pidfds by adding
  the P_PIDFD type to the waitid() syscall. This completes the basic
  functionality of the pidfd api (cf. [1]). In the meantime we also have
  a new adition to the userspace projects that make use of the pidfd
  api. The qt project was nice enough to send a mail pointing out that
  they have a pr up to switch to the pidfd api (cf. [2]).

  Second, this tag contains an extension to the waitid() syscall to make
  it possible to wait on the current process group in a race free manner
  (even though the actual problem is very unlikely) by specifing 0
  together with the P_PGID type. This extension traces back to a
  discussion on the glibc development mailing list.

  There are also a range of tests for the features above. Additionally,
  the test-suite which detected the pidfd-polling race we fixed in [3]
  is included in this tag"

f9af2dbbfe tcp: Add TCP_INFO counter for packets received out-of-order 
For receive-heavy cases on the server-side, we want to track the
connection quality for individual client IPs. This counter, similar to
the existing system-wide TCPOFOQueue counter in /proc/net/netstat,
tracks out-of-order packet reception. By providing this counter in
TCP_INFO, it will allow understanding to what degree receive-heavy
sockets are experiencing out-of-order delivery and packet drops
indicating congestion.

Please note that this is similar to the counter in NetBSD TCP_INFO, and
has the same name.

Also note that we avoid increasing the size of the tcp_sock struct by
taking advantage of a hole.

33f2c35a54 md: add feature flag MD_FEATURE_RAID0_LAYOUT 
Due to a bug introduced in Linux 3.14 we cannot determine the
correctly layout for a multi-zone RAID0 array - there are two
possibilities.

It is possible to tell the kernel which to chose using a module
parameter, but this can be clumsy to use.  It would be best if
the choice were recorded in the metadata.
So add a feature flag for this purpose.
If it is set, then the 'layout' field of the superblock is used
to determine which layout to use.

If this flag is not set, then mddev->layout gets set to -1,
which causes the module parameter to be required.

823eb2a3c4 PTP: add support for one-shot output 
Some controllers allow for a one-shot output pulse, in contrast to
periodic output. Now that we have extensible versions of our IOCTLs, we
can finally make use of the 'flags' field to pass a bit telling driver
that if we want one-shot pulse output.

415606588c PTP: introduce new versions of IOCTLs 
The current version of the IOCTL have a small problem which prevents us
from extending the API by making use of reserved fields. In these new
IOCTLs, we are now making sure that flags and rsv fields are zero which
will allow us to extend the API in the future.

Netfilter updates for net-next

The following patchset contains Netfilter updates for net-next:

1) Fix error path of nf_tables_updobj(), from Dan Carpenter.

2) Move large structure away from stack in the nf_tables offload
   infrastructure, from Arnd Bergmann.

3) Move indirect flow_block logic to nf_tables_offload.

4) Support for synproxy objects, from Fernando Fernandez Mancera.

5) Support for fwd and dup offload.

6) Add __nft_offload_get_chain() helper, this implicitly fixes missing
   mutex and check for offload flags in the indirect block support,
   patch from wenxu.

7) Remove rules on device unregistration, from wenxu. This includes
   two preparation patches to reuse nft_flow_offload_chain() and
   nft_flow_offload_rule().

Large batch from Jeremy Sowden to make a second pass to the
CONFIG_HEADER_TEST support and a bit of housekeeping:

8) Missing include guard in conntrack label header, from Jeremy Sowden.

9) A few coding style errors: trailing whitespace, incorrect indent in
   Kconfig, and semicolons at the end of function definitions.

10) Remove unused ipt_init() and ip6t_init() declarations.

11) Inline xt_hashlimit, ebt_802_3 and xt_physdev headers. They are
    only used once.

12) Update include directive in several netfilter files.

13) Remove unused include/net/netfilter/ipv6/nf_conntrack_icmpv6.h.

14) Move nf_ip6_ext_hdr() to include/linux/netfilter_ipv6.h

15) Move several synproxy structure definitions to nf_synproxy.h

16) Move nf_bridge_frag_data structure to include/linux/netfilter_bridge.h

17) Clean up static inline definitions in nf_conntrack_ecache.h.

18) Replace defined(CONFIG...) || defined(CONFIG...MODULE) with IS_ENABLED(CONFIG...).

19) Missing inline function conditional definitions based on Kconfig
    preferences in synproxy and nf_conntrack_timeout.

20) Update br_nf_pre_routing_ipv6() definition.

21) Move conntrack code in linux/skbuff.h to nf_conntrack headers.

22) Several patches to remove superfluous CONFIG_NETFILTER and
    CONFIG_NF_CONNTRACK checks in headers, coming from the initial batch
    support for CONFIG_HEADER_TEST for netfilter.

64f658ded4 devlink: add unknown 'fw_load_policy' value 
Similar to the 'reset_dev_on_drv_probe' devlink parameter, it is useful
to have an unknown value which can be used by drivers to report that the
hardware value isn't recognized or is otherwise invalid instead of
failing the operation.

This is especially useful for u8/enum parameters.

7396d337cf KVM: x86: Return to userspace with internal error on unexpected exit reason 
Receiving an unexpected exit reason from hardware should be considered
as a severe bug in KVM. Therefore, instead of just injecting #UD to
guest and ignore it, exit to userspace on internal error so that
it could handle it properly (probably by terminating guest).

In addition, prefer to use vcpu_unimpl() instead of WARN_ONCE()
as handling unexpected exit reason should be a rare unexpected
event (that was expected to never happen) and we prefer to print
a message on it every time it occurs to guest.

Furthermore, dump VMCS/VMCB to dmesg to assist diagnosing such cases.

27e022a9c6 btrfs: replace: BTRFS_DEV_REPLACE_ITEM_STATE_x defines should go 
The BTRFS_DEV_REPLACE_ITEM_STATE_x defines, as shown in [1], are
unused in both kernel and btrfs-progs (except for one instance of
BTRFS_DEV_REPLACE_ITEM_STATE_NEVER_STARTED in kernel).

[1]
btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_FINISHED        2
btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_CANCELED        3
btrfs.h:#define BTRFS_IOCTL_DEV_REPLACE_STATE_SUSPENDED       4

Further these define-values are different form its counterpart
BTRFS_IOCTL_DEV_REPLACE_STATE_x series as shown in [2].

[2]
btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_SUSPENDED   2
btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_FINISHED    3
btrfs_tree.h:#define BTRFS_DEV_REPLACE_ITEM_STATE_CANCELED    4

So this patch deletes the BTRFS_DEV_REPLACE_ITEM_STATE_x altogether, and
one instance of BTRFS_DEV_REPLACE_ITEM_STATE_NEVER_STARTED is replaced
with BTRFS_IOCTL_DEV_REPLACE_STATE_NEVER_STARTED in the kernel.

In commit c11d2c236c ("Btrfs: add ioctl to get and reset the device

Shortly thereafter, in commit b27f7c0c15 ("btrfs: join DEV_STATS
ioctls to one") , the flags field was added.  However, the calculation
for unused padding space was not updated, which also invalidated the
comment.

implementing this.

92f35b751c KVM: arm/arm64: vgic: Allow more than 256 vcpus for KVM_IRQ_LINE 
While parts of the VGIC support a large number of vcpus (we
bravely allow up to 512), other parts are more limited.

One of these limits is visible in the KVM_IRQ_LINE ioctl, which
only allows 256 vcpus to be signalled when using the CPU or PPI
types. Unfortunately, we've cornered ourselves badly by allocating
all the bits in the irq field.

Since the irq_type subfield (8 bit wide) is currently only taking
the values 0, 1 and 2 (and we have been careful not to allow anything
else), let's reduce this field to only 4 bits, and allocate the
remaining 4 bits to a vcpu2_index, which acts as a multiplier:

  vcpu_id = 256 * vcpu2_index + vcpu_index

With that, and a new capability (KVM_CAP_ARM_IRQ_LINE_LAYOUT_2)
allowing this to be discovered, it becomes possible to inject
PPIs to up to 4096 vcpus. But please just don't.

Whilst we're there, add a clarification about the use of KVM_IRQ_LINE
on arm, which is not completely conditionned by KVM_CAP_IRQCHIP.
